    THE  FOLLOWING SUMMARY  IS QUALIFIED  IN ITS  ENTIRETY BY  THE MORE DETAILED
INFORMATION, INCLUDING "RISK  FACTORS" AND  THE FINANCIAL  STATEMENTS AND  NOTES
THERETO,  APPEARING  ELSEWHERE  IN  THIS  PROSPECTUS.  THE  DISCUSSION  IN  THIS
PROSPECTUS  CONTAINS   FORWARD-LOOKING  STATEMENTS   THAT  INVOLVE   RISKS   AND
UNCERTAINTIES. THE COMPANY'S ACTUAL RESULTS AND THE TIMING OF CERTAIN EVENTS MAY
DIFFER   SIGNIFICANTLY  FROM  THE  RESULTS   DISCUSSED  IN  THE  FORWARD-LOOKING
STATEMENTS. FACTORS THAT COULD CAUSE OR CONTRIBUTE TO SUCH DIFFERENCES  INCLUDE,
BUT  ARE  NOT  LIMITED  TO, THOSE  DISCUSSED  IN  "RISK  FACTORS," "MANAGEMENT'S
DISCUSSION AND ANALYSIS OF  FINANCIAL CONDITION AND  RESULTS OF OPERATIONS"  AND
"BUSINESS."
 
                                  THE COMPANY
 
    Conductus,  Inc. ("Conductus"  or the "Company")  develops, manufactures and
markets electronic  components  and  subsystems based  on  superconductors.  The
unique  properties of superconductors provide  the basis for electronic products
with  significant  potential  performance  advantages  over  products  based  on
competing  materials  such  as  copper  and  semiconductors.  Depending  on  the
application, these advantages  include enhanced  sensitivity, efficiency,  speed
and  operating frequency, as well as reduced power consumption, size, weight and
cost. Conductus is currently focusing significant development, manufacturing and
marketing  efforts  on  applications  for   superconductors  in  the  areas   of
communications, healthcare and instrumentation.
 
    Superconductors  are materials that have the ability to transport electrical
energy with little or no loss when cooled below a "critical" temperature.  Since
its founding in 1987, the Company has focused its product development efforts on
high-temperature  superconducting ("HTS") materials discovered in the 1980s that
can  be   cooled  more   conveniently   and  economically   than   earlier-known
superconducting  materials. Based upon publicly available information, Conductus
believes that its technologies are more  advanced than those of other  companies
or  research  laboratories.  Conductus  combines  advanced  HTS  technology with
expertise  in  electronic  device  and  component  design,  analog  and  digital
electronic  engineering, cryogenic packaging,  mechanical engineering and system
integration.  Conductus   believes  that   systems  containing   superconductive
electronic  technology, if  successfully commercialized,  will offer performance
that is  unavailable  from  competing  technology,  will  reduce  the  costs  of
performing desired functions, or, in many cases, will do both.
 
    In  the communications market, Conductus is developing filter subsystems for
cellular and  personal  communication  services  ("PCS")  base  stations.  These
superconducting  filter subsystems  could provide  significant benefits  in base
station performance and reduce the size of the filter components. The Company is
developing and testing prototype integrated  subsystems that are designed to  be
easily integrated into new base stations or to allow cost-effective retrofitting
of  existing base  stations. Laboratory  and initial  field tests  of Conductus'
cellular  filter   subsystems  conducted   by  industry   representatives   have
demonstrated  performance improvements  over conventional  technology, including
enhanced base  station  receiver range.  Conductus  expects to  make  its  first
shipments  of  cellular filter  subsystems  in late  1996.  For the  PCS market,
Conductus is developing an integrated filter subsystem under a joint development
agreement with Lucent Technologies, Inc. ("Lucent"). The first field test of the
initial prototype of the  receiver portion of the  Conductus subsystem has  been
conducted  by Lucent. The Company believes  that providing its technology at the
subsystem level to selected OEM systems manufacturers such as Lucent will  allow
it to most rapidly and efficiently expand both its product line and its customer
base.
 
    In  the  healthcare market,  Conductus is  developing and  testing prototype
superconductive receiver  subsystems for  several  types of  magnetic  resonance
instruments.  Conductus is developing  a family of  probe subsystems for nuclear
magnetic  resonance   ("NMR")  spectroscopy   systems  for   Varian   Associates
("Varian"),  a leading manufacturer  of these systems.  In March 1996, Conductus
began manufacturing and selling two NMR probe types through Varian. The  Company
anticipates that it will introduce a third NMR probe type for commercial sale by
the  end of 1996. Conductus also  is developing receiver subsystems for magnetic
resonance imaging  ("MRI") scanners  under a  joint development  agreement  with
Siemens AG ("Siemens").
 
    In  the instrumentation  market, Conductus currently  manufactures and sells
superconducting sensors  called  Superconducting  Quantum  Interference  Devices
("SQUIDs"),  which can be used in electronic instruments to detect and precisely
locate  extremely  weak  magnetic  signals.  Conductus  is  also  marketing  and
developing  a variety of electronic components  and instruments based upon SQUID
technology.
 
    Conductus has leveraged its resources by developing superconductive products
in collaboration with corporate partners that are market and technology leaders,
research laboratories and government agencies. Since its inception, the  Company
has  received approximately $25.5  million in external  funding for research and
development, primarily from agencies of  the U.S. government, and currently  has
approximately  $3.4 million in  contracts and grants and  $7.8 million in awards
for future research and development.
 
    Conductus was incorporated in  Delaware in 1987.  Its principal offices  are
located  at 969 W. Maude Avenue,  Sunnyvale, California 94086, and its telephone
number is (408) 523-9950.

                                  RISK FACTORS
 
    IN  ADDITION  TO  THE  OTHER  INFORMATION  IN  THIS  PROSPECTUS, PROSPECTIVE
INVESTORS SHOULD CONSIDER THE FOLLOWING  RISK FACTORS INHERENT IN AND  AFFECTING
THE  BUSINESS  OF  THE  COMPANY.  THE  DISCUSSION  IN  THIS  PROSPECTUS CONTAINS
FORWARD-LOOKING STATEMENTS THAT INVOLVE  RISKS AND UNCERTAINTIES. THE  COMPANY'S
ACTUAL  RESULTS AND THE  TIMING OF CERTAIN EVENTS  MAY DIFFER SIGNIFICANTLY FROM
THE RESULTS  DISCUSSED IN  THE FORWARD-LOOKING  STATEMENTS. FACTORS  THAT  COULD
CAUSE  OR CONTRIBUTE TO SUCH DIFFERENCES INCLUDE,  BUT ARE NOT LIMITED TO, THOSE
DISCUSSED BELOW  AND  IN  "MANAGEMENT'S DISCUSSION  AND  ANALYSIS  OF  FINANCIAL
CONDITION AND RESULTS OF OPERATIONS" AND "BUSINESS."
 
    EARLY  STAGE  OF  THE  SUPERCONDUCTIVE ELECTRONICS  MARKET.    Conductus was
founded in September 1987 and to  date has been engaged principally in  research
and  development  activities.  Although  Conductus has  introduced  a  number of
superconductive electronic products,  most of Conductus'  revenues to date  have
been  derived from research and development contracts. See "Risk Factors -- High
Degree of Dependence upon Government Contracts." The superconductive electronics
market is new, with limited product  commercialization to date. There can be  no
assurance  that  Conductus will  successfully  introduce any  products currently
under  development,  that  Conductus  will  be  able  to  manufacture   adequate
quantities  of any products it introduces at commercially acceptable costs or on
a timely basis or that any such products will offer sufficient price/performance
advantages to achieve market acceptance.  The Company's failure to  successfully
develop,   manufacture   and  commercialize   products  that   offer  sufficient
price/performance advantages  to  achieve  significant market  acceptance  on  a
timely  and cost-effective  basis would  have a  material adverse  effect on the
Company's business, operating results and financial condition. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
    ACCUMULATED DEFICIT AND ANTICIPATED FUTURE LOSSES; UNCERTAINTY OF  FINANCIAL
RESULTS.    As of  March 31,  1996, the  Company had  accumulated net  losses of
approximately $25.6 million. Conductus  expects to incur substantial  additional
losses  at least during 1996 as  it expands operations. Continued development of
the Company's products may  require the commitment  of substantial resources  to
research and development, establishment of additional pilot and commercial-scale
fabrication  processes  and  facilities  and  development  of  enhanced  quality
control, marketing, sales and administrative  capabilities. In order to  achieve
profitability,  Conductus,  on  its  own or  with  collaborative  partners, must
successfully develop, manufacture, introduce and market its potential  products.
There  can  be  no assurance  that  the Company  will  ever be  able  to achieve
profitable  operations  or,  if  profitability  is  achieved,  that  it  can  be
sustained.
 
    QUARTERLY  FLUCTUATIONS.    The  Company's  operating  results  have  varied
substantially on  a  quarterly  basis  and such  fluctuations  are  expected  to
continue  and  perhaps  increase  in  future periods  as  the  Company  seeks to
commercialize its  products. Factors  that may  affect the  Company's  operating
results  include the timing of government  funding awards, the timing and market
acceptance of new  products or  technological advances  by the  Company and  its
competitors,  the timing of significant orders  from and shipments to customers,
changes in  pricing policies  by the  Company and  its competitors,  the mix  of
distribution  channels  through  which  the  Company's  products  are  sold, the
accuracy of resellers'  forecasts of  end user demand,  regulatory changes,  the
ability  of the Company and its  subcontractors to obtain sufficient supplies of
limited- or  sole-source  components  for the  Company's  products  and  general
economic  conditions  both domestically  and internationally.  See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
    HIGH DEGREE OF DEPENDENCE UPON OTHER COMPLEMENTARY TECHNOLOGIES.  Commercial
uses of  superconductive  products  will  depend  generally  on  the  commercial
availability  of a number  of other technologies  such as specialized mechanical
refrigeration systems, cryogenically-cooled semiconductor technology and  large-
area  compatible wafer substrates,  some of which are  in the development stage.
Conductus currently does not intend to devote significant effort or resources to
developing these technologies, and is dependent on the development activities of
third parties in these areas. There can be no assurance that these  technologies
will  be successfully  developed and commercialized,  or that  they will achieve
market acceptance.
 
    RELIANCE ON  LIMITED-  OR  SOLE-SOURCE SUPPLIERS.    Certain  components  of
Conductus'  subsystems,  including cryocoolers,  are  currently obtained  from a
single  source   or  a   limited   number  of   suppliers.  The   inability   of
 
                                       6
<PAGE>
the  Company to develop  alternative sources, if required,  an inability to meet
demand, a prolonged interruption in supply or a significant increase in price of
one or more  components would have  a material adverse  effect on the  Company's
business, operating results and financial condition.
 
    DEPENDENCE   ON  INCORPORATION   OF  POTENTIAL   PRODUCTS  IN   THIRD  PARTY
SYSTEMS.  Many of Conductus' potential products, if successfully developed,  are
likely  to be used as components or  subsystems in systems manufactured and sold
by third party systems manufacturers. There can be no assurance that these third
parties will elect to incorporate  superconductive electronic products in  these
systems  or,  if  they  do,  that  related  system  requirements,  such  as data
processing software  and  hardware capabilities,  can  or will  be  successfully
developed.  Failure of third parties to successfully commercialize complementary
technologies or to incorporate the  Company's products into their systems  would
have  a material  adverse effect on  Conductus' business,  operating results and
financial condition.
 
    EXTENSIVE  RELIANCE   ON  COLLABORATIVE   RELATIONSHIPS.     Conductus   has
established  and continues to seek  to establish collaborative arrangements with
corporate  partners,  government  agencies  and  public  and  private   research
institutions  to  develop,  manufacture  and  market  superconductive electronic
products. Conductus' success  will depend in  large part on  the development  of
successful  collaborative  arrangements  with  third  parties,  their  strategic
interest in the potential  products under development  and their willingness  to
purchase  any such products.  There can be  no assurance that  Conductus will be
able to enter into collaborative arrangements on commercially reasonable  terms,
that  these arrangements, if established, will  result in successful programs to
develop, manufacture or market superconductive electronic products or, if  these
programs are successful, that Conductus' collaborative partners will not seek to
manufacture   jointly  developed   products  themselves  or   obtain  them  from
alternative sources. In addition, these programs may require Conductus to  share
control   over  its  development,  manufacturing   and  marketing  programs  and
relinquish rights to its technology, may be subject to unilateral termination by
the Company's  collaborative partners  and may  restrict Conductus'  ability  to
engage in certain areas of product development, manufacturing and marketing. See
"--  High  Degree  of Dependence  Upon  Government Contracts"  and  "Business --
Strategic Alliances and Development Agreements."
 
    RAPID TECHNOLOGICAL CHANGE.  The field of superconductivity is characterized
by rapidly advancing technology. The future  success of the Company will  depend
in  large  part upon  its ability  to keep  pace with  advancing superconductive
technology, including  superconducting  materials and  processes,  and  industry
standards.  The Company has focused its  development efforts to date principally
on yttrium barium  copper oxide ("YBCO").  There can be  no assurance that  YBCO
will  ultimately prove  commercially competitive  against other  currently known
materials or materials that  may be discovered in  the future. The Company  will
have  to  continue  to develop  and  integrate  advances in  technology  for the
fabrication of electronic  circuits and  devices and  manufacture of  commercial
quantities  of its products. The  Company will also need  to continue to develop
and integrate advances in complementary technologies. There can be no  assurance
that the Company's development efforts will not be rendered obsolete by research
efforts  and technological advances made by  others or that materials other than
those currently  used by  Conductus will  not prove  more advantageous  for  the
commercialization of superconductive electronic products.
 
    INTENSE  COMPETITION.    The  market for  electronic  products  is intensely
competitive. Although the  market for superconductive  electronics currently  is
small  and in  the early stages  of development, Conductus  believes this market
will become intensely competitive if products with significant market  potential
are  successfully developed. A  number of large  American, Japanese and European
companies,  many  of  which  have  substantially  greater  financial  resources,
research  and development  staffs and  manufacturing and  marketing capabilities
than  the  Company,  are  engaged  in  programs  to  develop  and  commercialize
superconductive   electronic  technology  and  products.  A  number  of  smaller
companies  are  also  engaged  in   various  aspects  of  the  development   and
commercialization  of superconductive electronic products. Furthermore, academic
institutions, governmental  agencies  and  other  public  and  private  research
organizations  are engaged in development programs  that may lead to competitive
arrangements  for  commercializing   superconductive  electronic  products.   In
addition,  if the superconductor industry develops further, new competitors with
significantly greater  resources  are  likely to  enter  the  field.  Conductus'
ability  to  compete  successfully  will  require  it  to  develop  and maintain
technologically  advanced  products,   attract  and   retain  highly   qualified
 
                                       7
<PAGE>
personnel, obtain patent or other protection for its technology and products and
manufacture  and market its products,  either on its own  or with third parties.
The Company's inability to  compete successfully would  have a material  adverse
effect on the Company's business, operating results and financial condition. See
"Business -- Competition."
 
    COMPETING  TECHNOLOGIES.   The Company's  planned products,  if successfully
developed, will compete directly with other existing and subsequently  developed
products   which   use  competing   technologies.  In   wireless  communications
applications, there are  a number  of competing approaches  and technologies  to
increase  the  capacity  and improve  the  quality of  wireless  networks. These
approaches include  increasing the  number of  base stations,  increasing  tower
heights,  locating  filters and  amplifiers  at the  top  of antennas  and using
advanced antenna technology.  In healthcare imaging  and analysis  applications,
alternative  approaches  and  technologies  in  magnetic  resonance  instruments
include using  more  powerful magnets,  and  improving receiver  sensitivity  by
refrigerating conventional copper receiver coils. In magnetic sensing instrument
applications,  alternative  approaches  and  technologies  may  be  available to
perform functions addressable  by magnetic sensing  technology. Improvements  in
existing alternative approaches or the development and introduction of competing
approaches  or technologies  to the  Company's potential  products could  have a
material adverse  effect  on  the  Company's  business,  operating  results  and
financial  condition.  Failure of  the Company's  potential products  to compete
successfully with products  using competing technologies  would have a  material
adverse  effect  on  the  Company's business,  operating  results  and financial
condition.
 
    UNCERTAINTY OF PATENTS AND PROPRIETARY RIGHTS; RISK OF
LITIGATION.  Conductus  has received  17 U.S.  patents and  one related  foreign
patent  with  unexpired terms  ranging from  13 to  18 years  and has  18 patent
applications pending before the U.S. Patent  and Trademark Office. One of  those
patents,  for an MRI  coil, is currently involved  in an interference proceeding
before  the  U.S.  Patent   and  Trademark  Office.   See  "Business  --   Legal
Proceedings."  International counterparts of several  of these issued patents or
pending applications have been filed under the Patent Cooperation Treaty with  a
number  of applications  currently in  various countries  worldwide. The Company
will continue to file  other U.S. and key  international patent applications  as
part  of its  business strategy.  There can be  no assurance,  however, that its
pending applications will  result in issued  patents, that the  validity of  its
issued  patents will not be subject to  challenge or that third parties will not
be able to  design around the  patented aspects of  the Company's products.  The
Company   also  relies  upon  trade  secrets,  unpatented  know-how,  continuing
technological innovation, employee and third-party non-disclosure agreements and
the pursuit  of licensing  opportunities in  order to  develop and  enhance  its
competitive  position. The Company's  efforts to protect  its proprietary rights
may not be successful, however, in preventing their misappropriation or ensuring
that these  rights  will  provide  the Company  with  a  competitive  advantage.
Additionally,  certain of the issued patents and patent applications are jointly
owned by the  Company and  third parties.  Any party  has the  right to  license
rights  under such patents and applications, which could result in Conductus not
having exclusive control over such inventions.
 
    The  Company  believes  that,   since  the  discovery  of   high-temperature
superconductors  ("HTS") in 1986, several thousand patent applications have been
filed worldwide  and over  a thousand  patents  have been  granted in  the  U.S.
relating  to  superconductivity.  There  are  interference  proceedings  pending
regarding rights to inventions claimed in some of the applications. Accordingly,
the patent positions of companies using HTS technology, including Conductus, are
uncertain and involve  both complex legal  and factual questions.  Consequently,
there  is significant  risk that others,  including competitors  of the Company,
have obtained or will obtain patents relating to the Company's planned  products
or technology.
 
    A  patent issue  of particular importance  to the Company  relates to copper
oxides or "cuprates,"  that are used  to make HTS  products, including the  YBCO
compound  which is currently the basis  for the Company's business and products.
Conductus has neither obtained  any issued patents nor  has it filed any  patent
applications  covering the composition  of any cuprates  or other HTS materials.
However, several U.S. and  foreign patent applications filed  by IBM, AT&T,  the
University  of Houston,  the Naval  Research Laboratory  and others  are pending
regarding the composition of YBCO and  related HTS. See "Business --  Background
- --  Conductus'  Approach." The  Company understands  that  several of  such U.S.
applications are the subject of an interference proceeding currently pending  in
the  U.S. Patent and Trademark  Office (Interference No. 101,981). Additionally,
E. I.  du Pont  de  Nemours &  Co. ("DuPont")  has  notified Conductus  that  it
 
                                       8
<PAGE>
is  the exclusive licensee of  patents issued in Israel,  Sweden, Taiwan and the
United Kingdom covering the composition of YBCO  and a method for using YBCO  in
superconducting  applications.  DuPont  has  stated  that  it  is  interested in
sublicensing such  patents  to Conductus,  and  would consider  sublicensing  to
Conductus,  as  they  issue,  any other  foreign  and  U.S.  patent applications
licensed to DuPont by the University of Houston. The Company anticipates that it
will be required  to obtain  a license to  use YBCO  from one or  more of  these
parties in order to continue to develop and sell products based on YBCO.
 
    There  can be no assurance that the Company would be able to obtain licenses
to patents covering  YBCO compositions,  when issued,  or to  any other  patents
applicable  to the Company's business on  commercially reasonable terms. In such
an event,  the Company  could be  required to  expend significant  resources  to
develop  non-infringing  technology alternatives  or to  obtain licenses  to the
technology that  the  Company infringes  or  would  infringe. There  can  be  no
assurance  that the  Company would be  able to successfully  design around these
third party patents  or to obtain  licenses to technology  that it may  require.
Furthermore, there can be no assurance that the Company will not be obligated to
defend  itself at substantial cost against  allegations of infringement of third
party patents. An adverse outcome  in such a suit  could subject the Company  to
significant  liabilities to third parties, or require the Company to cease using
such technology. In  addition, aside from  the merits  of a claim,  the cost  of
defending  any  such suit  would  constitute a  major  financial burden  for the
Company that would  have a material  adverse effect on  the Company's  business,
operating results and financial condition. See "Business -- Patents, Proprietary
Technology and Trademarks."
 
    DEPENDENCE  ON  LICENSED TECHNOLOGY.    Successful marketing  of  a material
portion of Conductus' products depends in part on nonexclusive licenses obtained
from various licensors. There can be no assurance that such licenses will not be
terminated by licensors  or that  Conductus will  be able  to develop  alternate
products that do not require these or other licenses.
 
    SUBSTANTIAL  FUTURE CAPITAL NEEDS.  The Company to date has received limited
revenues from product sales. The  development of the Company's planned  products
will require a commitment of substantial additional funds. Conductus anticipates
that  its existing available cash, together with the estimated net proceeds from
this offering, should be  adequate to fund the  Company's operations through  at
least  the end of 1998. The Company's future capital requirements will depend on
many factors,  including  continued progress  in  its research  and  development
programs,  the  magnitude of  these  programs, the  time  and costs  involved in
obtaining any required  regulatory approvals, the  costs involved in  preparing,
filing, prosecuting, maintaining and enforcing patents, successful completion of
technological,  manufacturing  and  market  requirements,  changes  in  existing
research relationships, the availability of funding under government  contracts,
the  ability of the Company to establish collaborative arrangements and the cost
of manufacturing  scale-up and  the amount  and timing  of future  revenues.  If
adequate  funds  are  not  available,  the Company  may  be  required  to delay,
scale-back or eliminate one or more of its research and development programs  or
obtain funds through arrangements with collaborative partners or others that may
require  the  Company to  relinquish rights  to certain  of its  technologies or
potential products that the Company would not otherwise relinquish. There can be
no assurance that additional financing will be available on acceptable terms  or
at  all,  if and  when required.  See "Management's  Discussion and  Analysis of
Financial  Condition  and  Results  of  Operations  --  Liquidity  and   Capital
Resources."
 
    LIMITED  COMMERCIAL MANUFACTURING  CAPABILITY.  Conductus  has established a
limited production facility.  To date,  Conductus has focused  primarily on  the
development   of  its  fabrication  processes  and  the  production  of  limited
quantities of  superconducting thin  films and  components. Although  Conductus'
processing  technology is  derived principally  from semiconductor manufacturing
technology, the fabrication  of HTS components  entails additional  difficulties
because  of  specific  properties  unique  to HTS  materials.  There  can  be no
assurance that Conductus can develop enhanced processing technology necessary to
develop more advanced  superconducting devices  and circuits,  that the  Company
will  be able to attain  commercial yields in the  future, that the Company will
not suffer  recurring  yield problems  caused  by mask  defects,  impurities  in
materials  and  other factors  or that  the Company  can expand  its processing,
production control,  assembly, testing  and  quality assurance  capabilities  to
produce existing or planned superconductive
 
                                       9
<PAGE>
electronic  products in adequate commercial quantities. The Company's failure to
develop an adequate manufacturing capacity would have a material adverse  effect
on  the  Company's  business,  operating results  and  financial  condition. See
"Business -- Manufacturing."
 
    NEED TO DEVELOP INFRASTRUCTURE TO SUPPORT COMMERCIALIZATION.  Conductus  has
very  limited  experience  in  commercial  sales,  marketing  and  distribution.
Expanded sales, marketing  and customer  service capabilities  are also  needed.
There  can be  no assurance that  it will  be able to  establish adequate sales,
marketing and  distribution  capabilities or  be  successful in  gaining  market
acceptance for any of its potential products.
 
    LIMITED  OUTLETS FOR CERTAIN PRODUCTS.  The market for NMR systems is highly
concentrated, with estimates that approximately  85% of the worldwide market  is
divided  between Varian Associates ("Varian")  and Bruker Instruments. There can
be no assurance that Varian  will be successful in  marketing the NMR probes  or
systems  containing  Conductus probe  subsystems, that  Varian will  continue to
market the probes  or systems or  that the Company  will be able  to market  the
probes  or  systems through  other channels  should distribution  through Varian
prove  unsuccessful.  See  "Business  --  Strategic  Alliances  and  Development
Agreements."
 
    HIGH  DEGREE OF DEPENDENCE UPON GOVERNMENT CONTRACTS.  A significant portion
of the Company's revenues has been  derived from contracts with agencies of  the
U.S.   government.  The  Company's  revenue  from  government-related  contracts
represented approximately 85%, 77%, 82% and 78% of total revenue for the quarter
ended March  31, 1996  and for  fiscal 1995,  1994 and  1993, respectively.  The
Company's  contracts  involving the  U.S. government  are or  may be  subject to
various risks,  including: unilateral  termination for  the convenience  of  the
government;   reduction  or  modification  in  the   event  of  changes  in  the
government's requirements  or  budgetary constraints;  increased  or  unexpected
costs   causing  losses  or  reduced  profits  under  fixed-price  contracts  or
unallowable  costs  under  cost  reimbursement  contracts;  risks  of  potential
disclosure  of Conductus' confidential information to third parties; the failure
or  inability  of  the  prime  contractor  to  perform  its  prime  contract  in
circumstances  where Conductus is a subcontractor; the failure of the government
to  exercise  options   provided  for   in  the   contracts;  the   government's
nonexclusive,  royalty-free license to use  technology developed pursuant to the
contracts by  or on  behalf  of the  government  in certain  circumstances;  and
exercise  of "march-in" rights  by the government. March-in  rights refer to the
right of the  U.S. government  or government agency  to require  the Company  to
license to third parties patented technology developed under contracts funded by
the  government if the  contractor fails to continue  to develop the technology.
The programs in which  Conductus participates in many  cases extend for  several
years,  but are normally  funded on an  annual basis. There  can be no assurance
that the U.S. government will continue  its commitment to programs to which  the
Company's  development projects are applicable,  particularly in light of recent
legislative initiatives  to  reduce  the  funding  of  various  U.S.  government
agencies  and programs, or  that the Company can  compete successfully to obtain
funding pursuant to such programs. Conductus does not anticipate that government
contract revenues will grow at historical rates  in the future and there can  be
no  assurance that revenues from government  contracts will continue at historic
levels. A  reduction  in,  or  discontinuance of,  such  commitment  or  of  the
Company's participation in such programs would have a material adverse effect on
the Company's business, operating results and financial condition. See "Business
- -- Research and Development -- Government Contracts."
 
    HIGHLY  REGULATED  POTENTIAL PRODUCT  APPLICATIONS.   Some of  the Company's
potential products may be used as subsystems in medical devices, such as MRI and
NMR devices, which are subject to extensive governmental regulation in the  U.S.
by  the  Food and  Drug Administration  ("FDA")  and other  government agencies.
Regulation of medical  devices outside the  U.S. varies widely  from country  to
country.  The  clearance  and approval  process  for  both the  FDA  and foreign
regulatory authorities can be costly and time consuming and the Company will  be
largely  dependent upon the efforts of manufacturers of instruments that utilize
the Company's  subsystems  to  obtain  necessary  approvals.  There  can  be  no
assurance that any buyers of the Company's subsystems will be able to obtain any
necessary governmental approvals, or otherwise comply with applicable government
regulations.
 
    In  addition,  in some  states,  a certificate  of  need ("CON")  or similar
regulatory approval is  required prior  to acquisition of  medical equipment  or
introduction of a new service by hospitals or healthcare
 
                                       10
<PAGE>
providers.  CON regulations limiting the number  of new MRI machines or limiting
the  acquisition  of  magnetoencephalography  devices  could  adversely   impact
commercialization   of  those   products,  whether   or  not   they  incorporate
superconducting products supplied by the Company.
 
    In the communications area, the operation of cellular and PCS base  stations
is  regulated  in the  United States  by  the Federal  Communications Commission
("FCC"). Base stations and equipment marketed for use therein must meet specific
technical standards. The  Company's ability  to sell its  HTS filter  subsystems
will  depend upon  the ability  of base  station equipment  manufacturers and of
cellular base station operators to obtain and retain the necessary FCC approvals
and licenses. Any failure or delay of base station manufacturers or operators in
obtaining necessary  approvals  could have  a  material adverse  effect  on  the
Company's business, operating results and financial condition.
 
    ENVIRONMENTAL  REGULATIONS.  The Company is  subject to a number of federal,
state and local governmental regulations related to the use, storage,  discharge
and  disposal of  toxic, volatile or  otherwise hazardous chemicals  used in its
business. Any failure to comply with present or future regulations could  result
in  fines being  imposed on the  Company and  the suspension of  production or a
cessation of  operations.  In  addition, such  regulations  could  restrict  the
Company's  ability  to expand  or could  require the  Company to  acquire costly
equipment or to incur  other significant expenses  to comply with  environmental
regulations or to clean up prior discharges.
 
    ATTRACTION  AND RETENTION OF KEY EMPLOYEES.  The Company is highly dependent
upon the efforts of  its senior management  and technical team,  as well as  the
contributions  of its Scientific Advisory Board. The loss of the services of one
or more  members of  the  senior management  and  technical team  or  Scientific
Advisory   Board  could  impede  the  achievement  of  product  development  and
commercialization objectives. Due  to the  specialized technical  nature of  the
Company's  business, the  Company is also  highly dependent upon  its ability to
attract and retain qualified technical  and key management personnel.  Moreover,
the  Company is targeting its products  towards markets, such as communications,
healthcare and instrumentation, that require substantial industry knowledge  and
expertise.  The Company currently has limited expertise in these areas and it is
essential to  attract  qualified  personnel  with  expertise  in  manufacturing,
marketing,  sales and support in each of  its targeted markets. There is intense
competition for qualified personnel in the areas of the Company's activities and
there can be no assurance that the  Company will be able to continue to  attract
and  retain qualified personnel  necessary for the  development of its business.
See "Business -- Employees."
 
    VOLATILITY OF STOCK  PRICE.  There  has been significant  volatility in  the
market  price of  securities of  technology companies,  particularly those that,
like the Company, are still engaged primarily in product development activities.
See "Price  Range  of  Common  Stock  and  Dividend  Policy."  Factors  such  as
technology and product announcements by the Company or its competitors, disputes
relating to patents and proprietary rights and variations in quarterly operating
results  may have a significant impact on  the market price of the Common Stock.
In addition, the securities markets  have experienced volatility which is  often
unrelated  to the  operating performance of  particular companies.  In the past,
following periods of volatility in the  market price of a company's  securities,
securities  class action  lawsuits have  been instituted  against a  company. If
brought, such litigation could have a  material adverse effect on the  Company's
business, results of operations and financial condition.
 
    EFFECT  OF  CERTAIN  CHARTER PROVISIONS;  ANTITAKEOVER  EFFECTS  OF RESTATED
CERTIFICATE OF INCORPORATION  AND BYLAW  PROVISIONS AND  OF DELAWARE  LAW.   The
Board  of  Directors  has the  authority  to  issue up  to  1,000,000  shares of
Preferred Stock and to determine the price, rights, preferences, privileges  and
restrictions,  including voting rights, of those shares without any further vote
or action by the stockholders. The rights of the holders of Common Stock will be
subject to, and may be adversely affected  by, the rights of the holders of  any
Preferred  Stock that  may be  issued in the  future. The  issuance of Preferred
Stock could have the  effect of making  it more difficult for  a third party  to
acquire  a majority of the outstanding voting  stock of the Company. The Company
has no  present plans  to  issue shares  of  Preferred Stock.  Further,  certain
provisions of the Company's Restated Certificate of Incorporation and Bylaws and
of  Delaware corporate law could  delay or make more  difficult a merger, tender
offer  or  proxy  contest  involving  the  Company.  Among  other  things,   the
 
                                       11
<PAGE>
Company's  Restated Certificate of Incorporation does not permit stockholders to
act by written consent.  See "Description of Capital  Stock -- Preferred  Stock"
and  "--  Antitakeover  Effects of  Provisions  of the  Restated  Certificate of
Incorporation and Bylaws and of Delaware Law."
 
    SHARES  ELIGIBLE  FOR  FUTURE  SALE;  REGISTRATION  RIGHTS.    Sales  of   a
substantial number of shares of Common Stock in the public market following this
offering could adversely affect the market price for the Company's Common Stock.
The  number of shares of Common Stock available for sale in the public market is
limited by  restrictions under  the  Securities Act  of  1933, as  amended  (the
"Securities  Act"), and lock-up  agreements under which  certain holders of such
shares have agreed not to sell or otherwise dispose of any of their shares for a
period of 90 days after  the effective date of  this offering without the  prior
written   consent  of  Tucker  Anthony  Incorporated.  However,  Tucker  Anthony
Incorporated may, in its sole discretion and at any time without notice, release
all or any portion of the securities subject to lock-up agreements. As a  result
of  these  restrictions,  based on  shares  outstanding  as of  March  31, 1996,
5,308,123 shares of Common Stock will be freely tradable without restriction  or
further  registration under the Securities Act, unless purchased by "affiliates"
of the Company, as that  term is defined in Rule  144 under the Securities  Act,
including  the 1,000,000 shares of Common Stock offered hereby, 1,500,000 shares
registered pursuant  to  the Company's  initial  public offering  and  2,808,123
shares that have either been registered on Form S-8 or are restricted securities
that can be sold pursuant to Rule 144(k) or Rule 701 under the Securities Act. A
total  of 1,424,866 shares are  held by persons who  may be deemed affiliates of
the Company and will be eligible for sale on the date of this Prospectus subject
to the  restrictions of  Rule 144  ("Affiliate Shares").  All of  the  Affiliate
Shares  will  be  subject  to  lock-up  arrangements.  Furthermore,  holders  of
approximately 2,017,000 shares of Common  Stock and warrants to purchase  33,534
shares  of Common  Stock will  be entitled  to certain  registration rights with
respect to  such  shares. If  such  holders, by  exercising  their  registration
rights,  cause a large number of shares to  be registered and sold in the public
market, the sale  of such shares  could have  a material adverse  effect on  the
market  price for the Company's  Common Stock and would  have a material adverse
effect the Company's ability  to raise additional capital  when or if  required.
See  "Shares  Eligible for  Future Sale"  and "Description  of Capital  Stock --
Registration Rights."
 
    ABSENCE OF DIVIDENDS.   The Company has never  paid cash dividends and  does
not  anticipate paying  cash dividends  on the  Common Stock  in the foreseeable
future. See "Price Range of Common Stock and Dividend Policy."
 
    DILUTION.  The public offering price  will be substantially higher than  the
book  value  per  share of  the  currently outstanding  Common  Stock. Investors
purchasing  shares  in  this  offering  will  therefore  suffer  immediate   and
substantial  dilution. See "Dilution."  In addition, the exercise  of any of the
currently outstanding  warrants  or  stock  options would  likely  result  in  a
dilution of the value of the Common Stock. Moreover, the Company may at any time
in  the  future  sell  additional  securities  and/or  rights  to  purchase such
securities,  grant  additional  warrants,  stock  options  or  other  forms   of
equity-based incentive compensation to the Company's management and/or employees
to  attract and  retain such  personnel or in  connection with  the obtaining of
non-equity financing,  such  as  debt or  leasing  arrangements  accompanied  by
warrants  to purchase  equity securities  of the  Company. Any  of these actions
would have a dilutive effect upon the holders of the Common Stock.
 
   
    BROAD DISCRETION OF MANAGEMENT TO  ALLOCATE OFFERING PROCEEDS.  The  Company
anticipates  that the proceeds of this offering will be used for working capital
required to support expansion of its operations, new manufacturing equipment and
general corporate purposes. The amounts identified for the foregoing uses  under
"Use  of Proceeds"  in this  Prospectus are  estimates and  the amounts actually
expended for each  such purpose  and the timing  of such  expenditures may  vary
depending  upon  numerous  factors.  The Company's  management  will  have broad
discretion  in  determining  the  amount  and  timing  of  expenditures  and  in
allocating   the  net  proceeds  of  this  offering.  Such  discretion  will  be
particularly broad  with  respect to  the  40%  or $3,940,000  of  the  proceeds
available  for use for working capital and general corporate purposes. There can
be no assurance that the Company will allocate the net proceeds of this offering
in a manner that achieves  a positive rate of return  on such net proceeds.  See
"Use of Proceeds."

                                USE OF PROCEEDS
 
   
    The  net proceeds to  the Company from  the sale of  the 1,000,000 shares of
Common Stock offered hereby are estimated to be $9,940,000, at a public offering
price of $11.00  per share  and after  deducting the  underwriting discount  and
estimated offering expenses.
    
 
   
    The  Company anticipates that a significant portion of the net proceeds will
be used for  working capital  required to  support expansion  of its  operations
including increases in inventory and receivables, improvements in facilities and
expansion  of  manufacturing. The  Company currently  expects  to use  less than
$500,000  for  facilities  improvements  and  $2,500,000  on  new  manufacturing
equipment  during the next 24 months. The  Company also expects to use a portion
of the net  proceeds to repay  all amounts  outstanding under its  bank line  of
credit,   which  the  Company  anticipates   may  total  approximately  $500,000
immediately prior to the closing. As of March 31, 1996, there were no borrowings
under this credit  facility which  provides for borrowing  up to  the lesser  of
$2,000,000  or 75% of  eligible receivables, bears interest  at prime plus 0.50%
and expires in February 1997.  The Company also anticipates using  approximately
$2,500,000  of  the  net proceeds  for  the development  of  its superconducting
products. The  Company anticipates  that  the balance  of  the net  proceeds  of
$3,940,000  (40% of net proceeds) will be  added to working capital and used for
general corporate purposes, including research and development and expansion  of
the  manufacturing,  sales and  marketing  infrastructure. Management  will have
broad discretion  in  the application  of  the  net proceeds.  The  Company  may
consider using the net proceeds for the acquisition of complementary businesses,
products  or technologies. However, the Company  currently has no specific plans
with respect to any such acquisition. Pending such uses, the Company intends  to
invest  the  net  proceeds  in  short-term,  investment-grade,  interest-bearing
securities. See  "Risk Factors  -- Broad  Discretion of  Management to  Allocate
Offering Proceeds."

                                    DILUTION
 
   
    As  of  March  31,  1996, the  Company  had  a net  tangible  book  value of
$4,430,000, or approximately $0.77 per  share of outstanding Common Stock.  "Net
tangible  book value" represents the amount  of total tangible assets less total
liabilities. Without taking into account any  other changes in the net  tangible
book value after March 31, 1996, other than to give effect to the receipt by the
Company  of the net proceeds from the sale of the shares of Common Stock offered
by the Company hereby at  a public offering price of  $11.00 per share, the  pro
forma  net tangible book  value of the Company  as of March  31, 1996 would have
been $14,370,000, or $2.13 per share.  This represents an immediate increase  in
net  tangible book  value of  $1.36 per  share to  existing stockholders  and an
immediate dilution in net tangible book  value of $8.87 per share to  purchasers
of  Common Stock  in the offering  ("New Investors"). Dilution  is determined by
subtracting net tangible book value per share after the offering from the amount
of cash  paid by  a New  Investor for  a share  of Common  Stock. New  Investors
participating  in this offering will incur immediate, substantial dilution. This
is illustrated in the following table:

exercise of  outstanding  options and  warrants  as of  March  31, 1996  with  a
weighted  average exercise price  of $5.04 per  share. To the  extent options or

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    THIS MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS SECTION AND OTHER PARTS OF THIS PROSPECTUS CONTAIN FORWARD-LOOKING
STATEMENTS  THAT INVOLVE RISKS  AND UNCERTAINTIES. THE  COMPANY'S ACTUAL RESULTS
AND THE  TIMING OF  CERTAIN EVENTS  MAY DIFFER  SIGNIFICANTLY FROM  THE  RESULTS
DISCUSSED  IN  THE  FORWARD-LOOKING  STATEMENTS.  FACTORS  THAT  COULD  CAUSE OR
CONTRIBUTE TO SUCH DIFFERENCES INCLUDE, BUT ARE NOT LIMITED TO, THOSE  DISCUSSED
BELOW AND IN "RISK FACTORS" AND "BUSINESS."
 
OVERVIEW
 
    Conductus  develops,  manufactures  and  markets  electronic  components and
systems  based  on  superconductors  for  applications  in  the  communications,
healthcare  and instrumentation markets. In May 1993, Conductus acquired Tristan
Technologies, Inc. ("Tristan"), a San Diego, California-based company founded in
1991, that designed, manufactured and sold large-scale magnetic sensing  systems
and  instrumentation. In  June 1994, Tristan  became the  Conductus Instrument &
Systems Division. As  of March  31, 1996,  Conductus had  accumulated losses  of
approximately $25,602,000 and expects to incur additional losses at least during
1996  due to the Company's planned  expansion of operations. Conductus, alone or
with collaborative partners, must  successfully develop, manufacture,  introduce
and  market its potential products in  order to achieve profitability. Conductus
does not  expect to  recognize meaningful  product sales  until it  successfully
develops  and commercializes superconductive  components, systems and subsystems
that address significant market needs. See "Risk Factors."
 
RESULTS OF OPERATIONS
 
  QUARTERS ENDED MARCH 31, 1996 AND 1995
 
    The Company's total revenues increased  to $2,611,000 for the first  quarter
of  1996, a 30% increase over the $2,013,000  for the same period in 1995. Total
revenues consisted  primarily  of contract  revenue  and, to  a  lesser  extent,
product sales. Revenues under U.S. government research and development contracts
increased  to $2,214,000 in the period from $1,644,000 in the same period in the
prior year  and  represented 85%  and  82% of  total  revenue for  the  periods,
respectively.  The increase  in contract  revenues was  primarily due  to higher
levels of  government funded  research  and development  activity in  the  three
months  ended March  31, 1996,  compared with the  three months  ended March 31,
1995. At March 31, 1996, Conductus had approximately $3,364,000 in contracts and
grants and  $7,760,000  in  awards  for future  research  and  development.  The
recognition  of revenue and  receipt of payment pursuant  to these contracts and
awards are subject to numerous risks.
 
    Revenues from sales of large-scale superconducting magnetic systems, SQUIDs,
HTS thin films and other products increased to $397,000 in the first quarter  of
1996,  an 8% increase over  the $369,000 of product sales  in same period in the
prior year. The increase in  the first quarter of  1996 is primarily related  to
increased  sales of  magnetic sensing systems  and instruments.  Revenues in the
three months ended March 31, 1996 were  lower than revenues in the three  months
ended December 31, 1995 due primarily to the impact of delays in shipment of two
large  magnetic  sensing  systems  in  the  first  three  months  of  1996.  The
large-scale magnetic sensing systems have large unit prices and are sold in  low
volumes,  and thus significant fluctuations in  sales of these systems may occur
between quarters. Conductus  does not  expect to  recognize significant  product
sales   until  it  successfully   develops  and  commercializes  superconductive
components and systems addressing significant markets.
 
    Cost of products increased to $256,000 for the first quarter of 1996, a  54%
increase  over the $166,000 for the same period in 1995. The increase in cost of
products  was  directly  related  to  increased  product  sales.  Gross  margins
decreased  to 36%  in the  first quarter  of 1996  from an  unusually high gross
margin of 55% in
 
                                       17
<PAGE>
the comparable period  for the  prior year.  The reduction  reflects changes  in
commercial  product mix between the two quarters. Large systems margins may vary
based on options  included and  may have  downward impacts  on overall  margins.
Costs of contract revenues are included in research and development expenses.
 
    Research  and  development expenses  increased  to $2,743,000  in  the first
quarter of 1996, a 6% increase over the $2,578,000 for the same period in  1995.
The  increase is  directly related  to the  development of  commercial products,
particularly in both the cellular  and PCS communications markets. The  contract
cost  portion increased  ratably from period  to period. The  Company expects to
continue to incur significant research and  development expenses as it seeks  to
develop additional products.
 
    Selling, general and administrative expenses increased to $1,007,000 for the
first  quarter of 1996 from  $827,000 for the same  quarter in 1995. These costs
increased in 1996  compared to the  prior quarter due  to increased sales  costs
associated  with the representative network  for magnetic sensing and instrument
products  and  the  increasing  size  of  the  Company's  operations.  Headcount
increased to 105 at March 31, 1996 from 102 at March 31, 1995. To the extent the
Company  increases sales of commercial products,  there will be additional sales
and marketing costs over those incurred in the first quarter of 1996.
 
    Interest income was $27,000 in the first quarter of 1996 compared to $80,000
during the same quarter in 1995. The primary reason for the decrease was a lower
amount of cash and investments which was partly offset by higher interest rates.
Interest charges  increased on  the Company's  debt financing  to  approximately
$36,000 in the first quarter of 1996 compared to $24,000 for the same quarter in
1995,  due  to higher  outstanding debt  balances  incurred to  purchase capital
equipment.
 
    As a result of incurring losses, the Company has not incurred any income tax
liability. The  Company  has  established  a  valuation  allowance  against  its
deferred tax assets and reviews this allowance on a periodic basis. At such time
that  the Company believes that it is more likely than not that the deferred tax
asset will be realized, the valuation allowance will be reduced.
 
  YEARS ENDED DECEMBER 31, 1995, 1994 AND 1993
 
    The results of  operations of the  Company for the  year ended December  31,
1993  do  not  include  the  results  of  operations  of  Tristan  prior  to its
acquisition by Conductus on May 28, 1993.
 
    Total revenues increased to $10,582,000 in 1995 from $8,636,000 in 1994  and
$6,479,000 in 1993. Total revenues consist primarily of contract revenue and, to
a  lesser extent, product  sales. Revenues for  1993 do not  include revenues of
Tristan before May 28, 1993, which were $602,000 for the period. Revenues  under
U.S.  government research and  development contracts increased  to $8,148,000 in
1995 from $7,048,000 in 1994 and $5,070,000 in 1993 and represented 77%, 82% and
78% of  total revenue  in 1995,  1994 and  1993, respectively.  The increase  in
contract  revenues during 1995 and 1994 was largely attributable to the addition
of several  new  multi-year  government  contracts.  The  decrease  in  contract
revenues as a percentage of total revenues in 1995 compared with 1994 was due to
increasing  product sales.  Revenues under these  new contracts  are expected to
offset planned declines in revenues from contracts approaching the end of  their
terms.  The Company  had $3,930,000 and  $2,353,000 in contracts  and grants and
$9,228,000 and $4,838,000 in awards from U.S. government agencies as of December
31, 1995 and 1994, respectively.  Conductus does not anticipate that  government
contract  revenues will grow at historical  rates in the future. The recognition
of revenue and  receipt of payment  pursuant to these  contracts and awards  are
subject to numerous risks. See Note 12 of Notes to Financial Statements.
 
    Revenue  from sales of large-scale superconductive magnetic sensing systems,
SQUIDs, HTS thin films and other  products increased to $2,434,000 in 1995  from
$1,588,000 in 1994 and $1,409,000 in 1993, primarily due to an increase in sales
of magnetic sensing systems and instruments introduced late in 1994 and in 1995.
The  large-scale magnetic sensing systems have large unit prices and are sold in
low volumes, and  thus, the timing  of individual sales  and shipments of  these
systems  could result in significant period  to period fluctuations in revenues,
such as  the  fluctuation which  resulted  from the  delay  in shipment  of  two
magnetic sensing systems in the first quarter of 1996. Product sales for 1993 do
not  include $602,000 realized by Tristan from sales of superconducting magnetic
systems before May 28, 1993.
 
                                       18
<PAGE>
    Cost of product  sales were  $1,430,000, $975,000 and  $1,175,000 for  1995,
1994  and 1993, respectively. Gross margins were 41%, 39% and 17% for 1995, 1994
and 1993,  respectively. Gross  margins increased  in 1995  and 1994  over  1993
primarily due to lower margins in 1993 on initial system products which included
startup  costs. Startup costs on the  introduction of new products also affected
margins in  1995 but,  due  to broader  product lines,  the  effect was  not  as
substantial.
 
    The  Company's research and development expenses, including cost of contract
revenues, increased to $9,819,000 in 1995 from $9,201,000 in 1994 and $7,080,000
in 1993,  representing 65%,  68% and  67%, of  total operating  expenses in  the
respective  years. The increases in 1995 and  1994 reflected the increase in the
Company's overall research and development  activities, and emphasis on  efforts
in  communications  and  healthcare.  Research  and  development  includes  both
externally and  internally  funded  projects.  Externally  funded  research  and
development  programs,  primarily  under  contracts with  agencies  of  the U.S.
government, accounted for approximately  $9,176,000 of research and  development
expenses  in  1995,  $8,717,000  in  1994  and  $6,500,000  in  1993, reflecting
increased government  contract  and  research activity  throughout  the  period.
Current  levels  of expenditures  are expected  to  continue for  development of
commercial products, particularly in the communication and healthcare areas. Net
expenses do not include  a non-recurring charge of  $705,000 resulting from  the
acquisition  of  Tristan  in 1993.  The  Company  expects to  continue  to incur
significant research and development expenses  and these expenses are likely  to
increase as it seeks to develop additional products.
 
    Selling,  general  and  administrative expenses  increased  to approximately
$3,756,000 in 1995 from $3,336,000  in 1994 and $1,589,000  in 1993 or 25%,  25%
and 15%, respectively, of total operating expenses in 1995, 1994 and 1993. These
costs  increased in 1995 and 1994 compared to  1993 due to the increased size of
the Company as  a result of  the acquisition of  Tristan, significant  headcount
additions  and increasing  sales and  marketing activities.  Total headcount has
increased to 99  at December 31,  1995 from 96  at December 31,  1994 and 66  at
December  31, 1993. Increases in  1995 over 1994 also  include the selling costs
associated with expanding  the Company's representative  network of  independent
distributors  of magnetic sensing and instrumentation products. Included in 1994
expenses is a non-recurring charge  of approximately $230,000 for severance  and
recruitment   expenses  associated   with  management   changes  and  additions.
Additionally, the Company expects  sales and marketing  expenses to continue  to
increase as it begins to market commercial products.
 
    The Company's total operating expenses increased to $15,005,000 in 1995 from
$13,513,000 in 1994 and $10,549,000 in 1993. Operating expenses for 1993 include
a non-recurring charge of $705,000 associated with purchased technology from the
acquisition of Tristan.
 
    Losses  from operations were $4,423,000, $4,876,000 and $4,070,000 for 1995,
1994 and  1993, respectively.  Excluding the  non-recurring charge  of  $705,000
resulting  from the  acquisition of Tristan,  the loss from  operations for 1993
would have been  $3,365,000. The decreasing  loss in 1995  compared to 1994  was
primarily  related  to planned  increases in  revenues  offset by  headcount and
contract costs  as  the  Company moved  toward  developing  and  commercializing
products.
 
    Interest income from cash equivalents and investments were $249,000 in 1995,
$344,000  in 1994  and $166,000  in 1993.  The primary  reasons for  the changes
between years were  changes in levels  of cash equivalents  and investments,  as
approximately  $13 million was received in the Company's initial public offering
in August 1993, and thereafter there have been reductions to support  operations
through 1994 and 1995.
 
    Interest charges were $156,000, $56,000 and $176,000 in 1995, 1994 and 1993,
respectively.  Interest  charges related  to the  Company's equipment  term loan
financing which commenced in September 1994  were reflected for the entire  year
compared to a minimal amount in 1994. The decrease in interest charges from 1993
to  1994 was primarily  due to the  maturing of portions  of the three equipment
lease lines. As of year end, only two lease line obligations remain at a reduced
level due to  maturities. Additionally,  in 1993 the  Company incurred  interest
charges of $86,000 related to its bridge loan financing.

    As a result of incurring losses, the Company has not incurred any income tax
liability.  The  Company  has  established  a  valuation  allowance  against its
deferred tax assets and reviews this allowance on a periodic basis. At such time
that the Company believes that it is more likely than not that the deferred  tax
asset will be realized, the valuation allowance will be reduced.
 
    Conductus  does not believe that inflation has  had a material effect on its
financial condition or results of operations during the past three fiscal years.
However, there  can be  no assurance  that the  Company's business  will not  be
affected by inflation in the future.
 
    During  March 1995, the Financial  Accounting Standards Board ("FASB")issued
Statement No. 121, "Accounting for the  Impairment of Long-Lived Assets and  for
Long-Lived  Assets  to  Be  Disposed  Of" ("SFAS  121").  SFAS  121  will become
effective for  the Company's  year ending  December 31,  1996. The  Company  has
studied  the implications of SFAS 121 and, based on its initial evaluation, does
not expect it to have a material impact on the Company's financial condition  or
results of operations.
 
    During  October 1995,  the FASB  issued Statement  No. 123,  "Accounting for
Stock-Based Compensation"  ("SFAS 123")  which established  a fair  value  based
method  of accounting for stock-based compensation plans and requires additional
disclosures for  those  companies who  elect  not to  adopt  the new  method  of
accounting.  The Company will  continue to account  for employee purchase rights
and stock options  under APB  Opinion No. 25,  "Accounting for  Stock Issued  to
Employees." SFAS 123 disclosures will be effective for the Company's year ending
December 31, 1996.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    As  of March  31, 1996, the  Company's aggregate cash,  cash equivalents and
short-term and long-term investments  totaled $2,110,000 compared to  $3,153,000
as  of December 31, 1995 and $7,538,000 as of December 31, 1994. The Company has
financed its operations  since inception  primarily through  $13,251,000 in  net
proceeds  from  its initial  public  offering of  Common  Stock in  August 1993,
$14,645,000 raised  in  private  financings, $25,529,000  from  U.S.  government
contracts,  $4,823,000 in aggregate borrowings under three equipment lease lines
of credit and equipment term loan and $3,183,000 in interest income.
 
    Net cash used in  operations was $4,625,000,  $3,578,000 and $2,795,000  for
1995,  1994 and 1993, respectively. The increase  in net cash used in operations
in 1995  over  the prior  years  was due  primarily  to increased  size  of  the
Company's  operations  including headcount  and other  related costs,  which was
partially offset by increased revenues. A significant portion of the increase is
related to increased  receivables on government  contracts and prepaid  expenses
and  other current assets, offset to some extent by increased accounts payables.
The prior  year was  also affected  by the  non-recurring charge  for  purchased
technology of $705,000.
 
    Net  cash used in operations was $1,061,000  for the first quarter period of
1996. The net cash used in operating activities in the first quarter of 1996 was
primarily due to operating losses and to a lesser extent increases in  inventory
which  were partially offset  by reductions in  accounts receivables and prepaid
expenses and  other  current  assets  and  other  related  costs.  Increases  in
inventory  were due to an increase in  inventory related to new NMR products and
sensor products  and a  delay in  the first  quarter in  shipment of  two  large
magnetic  sensing systems. The Company  anticipates that its accounts receivable
from revenues under  U.S. government  contracts and  product sales,  as well  as
inventories, may increase during 1996. Any such increases will result in the use
of additional cash in operating activities.
 
   
    During  1995 and 1994, net cash of $2,670,000 and $1,743,000 was provided by
investing activities  from  the reduction  in  investments partially  offset  by
purchases  of property and  equipment. During 1993, net  cash of $10,458,000 was
used in  investing  activities  from  funding received  on  the  initial  public
offering.  Purchases  of  property and  equipment  in 1995  were  $1,568,000, an
increase of $342,000 over  the prior year  primarily reflecting expenditures  to
expand  the  Company's  facilities  in  1995  which  approximated  $681,000  and
increased equipment needs for research and development and operations.
    
 
    Net cash from investing activities was  $1,129,000 for the first quarter  of
1996.  Net  cash  was  provided by  net  reductions  in  short-term investments,
partially offset by purchases of property and equipment.
 
                                       20
<PAGE>
    Net cash from financing activities was $1,722,000, $269,000 and  $14,933,000
in  1995, 1994 and 1993, respectively. Net cash provided by financing activities
in 1995 and 1994 was primarily  due to borrowings under the Company's  equipment
term  loan  offset by  principal payments  under  capital lease  obligations and
proceeds from issuance of  shares under the 1994  Employee Stock Purchase  Plan.
Net  cash provided  by financing  activities in  1993 was  primarily due  to the
Company's initial public offering in August 1993, its private placement in  June
1993, and bridge loan financings which were converted into equity in the private
placement,  offset  by  principal  payments  under  capital  lease  obligations,
equipment term loan and debt assumed in the Tristan acquisition.
 
    Net cash from  financing activities was  $241,000 for the  first quarter  of
1996, primarily due to borrowings under the Company's equipment term loan offset
by principal payments under capital lease obligations.
 
    Conductus  anticipates that its existing available  cash, its line of credit
of $2,000,000 and term  loan facility for fixed  assets of $1,000,000 should  be
adequate  to fund the Company's operations through at least the end of 1996. See
Note 10 of Notes to Financial Statements and "Use of Proceeds." There can be  no
assurance  that additional funding, if required, will be available on acceptable
terms or at all.
 
    The actual amount of the  Company's future capital requirements will  depend
on  many factors, including  continued progress in  its research and development
programs, the  magnitude of  these  programs, the  time  and costs  involved  in
obtaining  any required regulatory  approvals, the costs  involved in preparing,
filing, prosecuting, maintaining and enforcing patents, successful completion of
technological, manufacturing  and marketing  requirements, changes  in  existing
research  relationships, the availability of funding under government contracts,
the ability of the Company to establish collaborative arrangements and the  cost
of  manufacturing scale-up and the amount of future revenues. The development of
the Company's potential products will require a commitment of substantial  funds
to  conduct  further  research  and development  and  testing  of  its potential
products,  to  establish  commercial-scale  manufacturing  and  to  market   any
resulting  products. The Company expects to  use significant amounts of cash for
capital equipment and  to support operations  until sufficient product  revenues
are  generated. There can be no assurance that the U.S. government will continue
its commitment  to programs  to  which the  Company's development  projects  are
applicable,  particularly in light  of recent legislative  initiatives to reduce
the funding  of various  U.S.  government agencies  and  programs, or  that  the
Company  can compete successfully  to obtain funding  pursuant to such programs.
Conductus does not  anticipate that  government contract revenues  will grow  at
historical  rates in the future and there can be no assurance that revenues from
government contracts  will  continue at  historic  levels. A  reduction  in,  or
discontinuance  of, such  commitment or of  the Company's  participation in such
programs would  have  a  material  adverse effect  on  the  Company's  business,
operating results and financial condition.

    Conductus develops,  manufactures  and  markets  electronic  components  and
subsystems  based on  superconductors. The unique  properties of superconductors
provide the basis for electronic products with significant potential performance
advantages over  products  based  on  competing materials  such  as  copper  and
semiconductors.  Depending on the application, these advantages include enhanced
sensitivity, efficiency, speed and operating frequency as well as reduced  power
consumption, size, weight and cost.
 
    Conductus   is  currently   focusing  significant   development  efforts  on
applications   for   superconductors    in   communications,   healthcare    and
instrumentation.  In the  communications market, Conductus  is developing filter
subsystems  for  cellular  and  personal  communication  services  ("PCS")  base
stations.  These  superconducting  filter subsystems  could  provide significant
benefits in  base  station  performance  and  reduce  the  size  of  the  filter
components.  In  the  healthcare  market, Conductus  is  developing  and testing
prototype superconductive  receiver subsystems  for  several types  of  magnetic
resonance    instruments,   including   nuclear   magnetic   resonance   ("NMR")
spectrometers and  magnetic  resonance  imaging ("MRI")  scanners.  The  Company
currently  manufactures and sells  a limited number  of superconducting receiver
probe subsystems for NMR spectrometers. In the instrumentation market, Conductus
currently manufactures and sells superconducting sensors called  Superconducting
Quantum  Interference Devices ("SQUIDs"), which can  be used to build electronic
instruments that detect  and precisely locate  extremely weak magnetic  signals.
Conductus  is also marketing  and developing a  variety of electronic components
and instruments based on SQUID technology.
 
BACKGROUND
 
  SUPERCONDUCTORS
 
    Superconductors are materials that have the ability to transport  electrical
energy  with little  or no  loss when  cooled to  a "critical"  temperature. The
intrinsic properties of superconductors are unique in nature and offer potential
performance  benefits  to  electrical  and  electronic  systems.  These  include
low-loss   signal  transmission,  extreme  magnetic  sensitivity  and  efficient
high-speed switching. When electrical currents flow through ordinary  materials,
they  encounter resistance which consumes energy by converting electrical energy
into heat energy. Depending on whether direct or alternating current is applied,
superconductors have  the  ability  to  transport  electrical  current  with  no
resistance at all or with only a tiny fraction (typically less than one percent)
of what is found in the best conventional conductors. This property is extremely
beneficial in electronic components whose increased efficiency leads to enhanced
signal  strength,  improved signal  resolution  and reduced  component  size and
weight. Other intrinsic properties of superconductors enable the fabrication  of
unique  electronic devices, including high-speed  electronic switches and ultra-
sensitive magnetic sensors.
 
    From 1911,  when superconductivity  was first  discovered, until  1986,  the
critical  temperatures  for  all  known  superconductors  did  not  exceed  23 K
(-418 DEG. F). As a result, superconductivity was not widely used in  commercial
applications  because of the high cost and complexities associated with reaching
and maintaining such low temperatures. In  1986, a new class of  superconducting
materials,   referred  to  as   high-temperature  superconductors  ("HTS"),  was
discovered having critical temperatures  above 77 K (-320  DEG. F), the  boiling
point  of liquid nitrogen. These high  critical temperatures allow HTS materials
to be  cooled  to  a  superconducting state  using  liquid  nitrogen,  which  is
inexpensive  and relatively easy  to use, or  using relatively simple mechanical
refrigerators. Conductus believes that  this ability to  obtain the benefits  of
superconducting  technology at  more easily  achieved temperatures  enables much
broader commercial applications.

  CONDUCTUS' APPROACH
 
    Conductus develops,  manufactures  and  markets  superconductive  electronic
devices  and  components  using  thin-film technology  based  upon  the material
yttrium barium copper oxide  ("YBCO"), which the Company  has judged to be  best
suited  for electronic applications.  Conductus combines what  it believes to be
the world's most advanced YBCO thin-film technology with expertise in electronic
device  and  component  design,  analog  and  digital  electronic   engineering,
cryogenic  packaging, mechanical  engineering and  system integration. Conductus
believes that  systems  containing superconductive  electronic  technology  will
offer performance that is unavailable from competing technology, will reduce the
costs of performing desired functions, or, in many cases, do both.
 
    CHOICE  OF MATERIAL.  Although  a number of high-temperature superconductors
have been identified,  Conductus has focused  upon the development  of YBCO  for
electronic  applications.  See  "Risk  Factors  --  Uncertainty  of  Patents and
Proprietary Rights; Risk of Litigation." YBCO is the only HTS material for which
there has  been both  significant development  and successful  demonstration  of
multilayer  technology, i.e., the use  of multiple thin-film materials deposited
one upon  another.  Conductus  believes  that  such  multilayer  structures  are
important for many electronic components and devices, where they can be used for
better  film quality and stability  and enhanced device functionality. Conductus
has developed  several  proprietary  processes  for  producing  YBCO  and  other
thin-film  materials as well  as for fabricating  superconducting components and
devices. These processes include thin-film growth, photolithography, etching and
other standard procedures used in the manufacture of electronic devices.
 
    THIN-FILM EXPERTISE.  Conductus produces superconducting components using  a
thin-film  fabrication  approach.  The  Company's  superconductive  circuits and
components are fabricated on the  surface of wafers using vapor-phase  thin-film
growth   and  standard  circuit  processing  steps  similar  to  those  used  to
manufacture  semiconductor  devices.   Furthermore,  the   fabrication  of   HTS
components  and circuits entails specialized processes, which are the subject of
Conductus' patents or proprietary know-how, in  order for HTS materials such  as
YBCO  to  exhibit  desirable  superconducting  properties.  Conductus,  in  many
instances, has performed pioneering work in materials, processes and  structures
based  on thin-film superconductive  technology, and has  developed processes it
believes are capable of routinely producing  a variety of high quality films  in
quantity  for several applications, including multiple layer thin-film materials
suitable for  more  complex devices  and  components. Compared  to  "thick-film"
approaches  and ceramic  fabrication techniques,  the Company  believes that the
thin-film approach is more  versatile and provides  more compact components  and
that  the superconducting properties  of the materials produced  in this way are
superior.
 
    FOCUS ON  COMPLETE  SOLUTIONS.    Conductus  believes  that  superconductive
component technology can best be provided to customers in the form of integrated
subsystems  that incorporate the components,  additional electronic circuits and
devices, and the self-contained  refrigeration equipment and packaging  required
to maintain the reduced temperatures necessary to sustain superconductivity. For
this  reason,  in  addition  to  its  thin-film  expertise,  Conductus  has also
established significant expertise  and know-how  in areas that  it believes  are
necessary   for  the  commercial   development  of  superconductive  technology,
including electronic device and component design, analog and digital  electronic
engineering, cryogenic packaging (including cryoelectronics, thermal management,
vacuum   engineering  and   cryocoolers),  mechanical   engineering  and  system
integration. Conductus  seeks  to  make  the  presence  of  superconductive  and
cryogenic  components an entirely internal feature of its products that requires
no special expertise or skill on the  part of the user. By skillful  integration
of  the  refrigeration  system  into its  communications  filter  subsystem, for
example, and by selection  of a refrigeration  approach with proven  durability,
Conductus  believes  that  its  products can  be  easily  accommodated  and well
accepted by end  users. Similarly,  the Company's NMR  probe is  designed to  be
readily  installed into existing  NMR systems in essentially  the same manner as
conventional probes. The Company believes  that providing its technology at  the
subsystem  level to  system manufacturers in  specific markets will  allow it to
rapidly and efficiently expand both its product line and its customer base.

    SIGNIFICANT  COMPANY  MILESTONES.     Since   establishing  its   laboratory
facilities  in 1989, Conductus  has made significant  and continuous progress in
establishing the enabling  technologies for its  target applications. The  table

BUSINESS AND DEVELOPMENT STRATEGY
 
    Conductus'    strategy   for   developing,   manufacturing   and   marketing
superconductive electronics products includes the following key elements:
 
    MAINTAIN TECHNOLOGY LEADERSHIP.  Conductus has devoted significant resources
to developing proprietary HTS thin-film manufacturing and process  technologies.
Based   on  publicly  available  information,  the  Company  believes  that  its
technologies are  more  advanced  than  those of  other  companies  or  research
laboratories.  The  Company  has successfully  developed  and  marketed products
including single- and  multilayer YBCO films,  superconducting NMR  spectroscopy
probes  and SQUID  sensors and  systems. Conductus  has utilized  its technology
skills to develop filters,  low-noise amplifiers, radio-frequency receivers  and
other devices. Conductus has also established significant expertise and know-how
in areas essential to product commercialization, including electronic device and
component   design,  analog   and  digital   electronic  engineering,  cryogenic
packaging, mechanical engineering and system integration. Conductus has received
17 U.S. patents and  one related foreign patent  and has 18 patent  applications
pending  in the U.S. and related patents  pending in other countries relating to
various aspects of its technologies.
 
    Since its inception,  Conductus has maintained  a Scientific Advisory  Board
composed  of  experts in  superconducting materials,  devices and  science. This
group continues  to contribute  to  the activities  and  knowledge base  of  the
Company.
 
    COMMERCIALIZE   PRODUCTS  WITH  SIGNIFICANT  MARKET  POTENTIAL.    Conductus
believes that the largest  potential near-term markets for  superconductor-based
products  exist in  wireless communications  and healthcare  applications and is
actively developing HTS component-based subsystems for these markets. See  table
on  page  26. In  the cellular  market, Conductus  has completed  laboratory and
initial field  tests  of  its  low-noise receiver  filter  subsystems  for  base
stations  and expects to commence commercial sales in late 1996. In the emerging
PCS  market,   Conductus  is   developing  integrated   transceiver   subsystems
incorporating  HTS transmit and receive filters, cryocooled low-noise amplifiers
and refrigeration equipment. In the  healthcare market, Conductus has  developed
and  currently sells several types of  probe subsystems for NMR spectrometers on
an OEM  basis  to  Varian. In  addition,  the  Company plans  to  develop  other
spectrometer  probe types during 1996 as  well as demonstrate prototype receiver
coil subsystems for MRI machines in late 1996.
 
    LEVERAGE  STRATEGIC  ALLIANCES.    Conductus'  strategy  is  to  enter  into
collaborative arrangements with market leaders in its target markets in order to
allow  the  Company to  focus primarily  on  the development  of superconductive
components and  subsystems  for use  in  products that  address  these  markets.
Conductus   has   entered  into   joint   development  agreements   with  Lucent
Technologies, Inc. in PCS communications, Varian Associates in NMR  spectroscopy
and  Siemens AG in MRI. It has  also entered into agreements whose primary focus
is technology development for a range of applications, including agreements with
TRW, Inc. ("TRW") and Northrop-Grumman Corporation (originally with Westinghouse
Electric Corporation) for development of digital electronics technology; and the
High-temperature Superconductor  Thin-film Manufacturing  Alliance ("HTMA")  for
development  of commercial, thin-film HTS manufacturing processes. Additionally,
Conductus has funded its development  programs and enhanced its development  and

    PROVIDE   COMPLETE  SOLUTIONS.    Conductus  believes  that  superconductive
component technology can best be provided to customers in the form of integrated
subsystems that incorporate the  components, additional electronic circuits  and
devices,  and the self-contained refrigeration  equipment and packaging required
to  maintain  the  operating  temperatures  necessary  for  the  superconductive
components.  Conductus  seeks  to  make  the  presence  of  superconductive  and
cryogenic  components   an   entirely   internal   feature   of   its   products

that requires no special expertise or skill on the part of the user. The Company
believes  that  providing  its  technology  at  the  subsystem  level  to system
manufacturers in specific markets will allow it to most rapidly and  efficiently
expand both its product line and its customer base.
 
    DEVELOP COMMERCIAL INFRASTRUCTURE.  Conductus is building the manufacturing,
sales  and  marketing infrastructure  it believes  is  necessary to  support the
commercialization of its products in  target markets. This includes  development
of  thin-film deposition techniques suitable for volume manufacture, acquisition
and build-out  of manufacturing  and assembly  areas, hiring  of employees  with
significant marketing experience in key product areas and expansion of its sales
team.  The  Company's  sales and  marketing  strategy is  to  use manufacturers'
representatives supplemented by a small  direct sales organization for sales  of
its  laboratory  instrument  products and  to  rely  primarily on  OEMs  for its
subsystem  products  for  the  communications,  healthcare  and  instrumentation
markets.

CONDUCTUS' TARGET APPLICATIONS
 
    The  unique properties of  superconductors provide the  basis for electronic
products with significant potential  performance advantages over products  based
on competing materials such as copper and semiconductors. Conductus is currently
focusing  significant development  efforts on  products for  applications in the
communications, healthcare  and instrumentation  markets for  which it  believes
there  is the greatest near-term market  potential. Conductus is also developing
additional technology for longer-term  applications such as high-speed  circuits
for  the communications  market and NMR  microscopes for  the healthcare market.
Conductus' products  are designed  to be  used as  components or  subsystems  in
systems manufactured by third party systems manufacturers in the communications,
healthcare  and instrumentation markets. The following discussion identifies the
broader market for the applications  of Conductus' potential customers and  then
specifies the Conductus solution targeted to those applications.
 
  COMMUNICATIONS
 
    Cellular  and  PCS communications  systems  use radio  frequency  signals to
establish communications between customers  using portable or mobile  telephones
and base stations operated by service providers. Cellular telephone networks are
divided  into specific  coverage areas  called cells, each  of which  has a base
station for  sending and  receiving voice  and other  communications within  the
cell.  The  base  station contains  electronic  equipment required  to  send and
receive radio signals. In setting up a base station, the service provider  seeks
to  install  equipment with  sufficient  sensitivity within  the  frequency band
assigned to it to handle communications with the lowest power handsets over  its
entire  geographical area and  with sufficient selectivity  to avoid interfering
signals from adjacent frequency bands. Filters within these base stations select
frequencies  within   the  operators'   assigned  bands   and  reject   unwanted
frequencies.  Amplifiers boost the strength of signals  coming in and out of the
base station. The operator's  assigned frequency range  is then allocated  using
one of several schemes to provide telephone service to multiple subscribers. The
capacity  of the system depends upon the  number of effective channels, that is,
channels whose  signal quality  is sufficient  to satisfy  customer demands  for
clear communications.
 
    Cellular  base stations currently face a number of operating problems. These
include signal  interference caused  by multiple  communications channels,  poor
signal  quality  resulting from  lower-power,  handheld telephones  and strained
capacity due  to the  growing demand  for cellular  service. The  advent of  PCS
technology  will place  additional demands on  the performance  of wireless base
stations and upon the size of the hardware therein. Power losses resulting  from
the use of components made from conventional conductors have limited the ability
of   the   industry  to   address  these   problems.  Conductus   believes  that
superconductive filters used in conjunction with cryogenically-cooled amplifiers
have the potential to offer solutions to several operating problems in  cellular
base  stations  as  well as  to  provide  solutions to  anticipated  problems in
forthcoming PCS base stations.
 
    CELLULAR  MARKET.    According  to  Federal  Communications  Commission  and
industry reports, there are more than 22,000 installed cellular base stations in
the United States. Of the U.S. installed base, Conductus estimates approximately
2,000-3,000   are  located  in   a  rural  environment.   The  present  cellular
communications network, operating at frequencies  near 850 MHz, was  established
at  a time  when the  typical cellular  telephone was  a mobile  unit capable of
transmitting up to  3 watts of  radio frequency  power and the  total number  of
subscribers  was relatively low. Today, portable handsets that transmit only 0.6
watts  are  increasingly  replacing  higher-power  mobile  telephones,   thereby
decreasing the effective receiving range of existing base stations. As a result,
in  rural  areas  where base  stations  are widely  separated,  current cellular
customers can experience dropped calls due  to "dead zones" in coverage. At  the
same  time, the increasing demand for cellular service in urban areas has led to
the utilization by  service providers  of a  greater number  of channels  within
their   allotted   frequency  bands,   thereby   increasing  the   incidence  of
interference.
 
    In rural areas, where the primary  problem is base station range,  solutions
that  increase the strength of the received  signal or decrease the system noise
level can provide  enhanced reception, and  thus reduce the  occurrence of  dead
zones.  One solution, which entails significant costs, is to increase the number
of base stations and thereby reduce the required range for each station. Another
solution, which is potentially more
 
                                       28
<PAGE>
economical, is to enhance the signal reception and noise filtering  capabilities
of  existing base  stations. Approaches to  enhance the  performance of existing
base stations include increasing  the height of towers  or locating filters  and
amplifiers  at the tops of towers to reduce the loss of electrical energy as the
signals travel through cables  from the antenna to  the receiver. Each of  these
solutions  has  shortcomings  with respect  to  such issues  as  cost, servicing
logistics and ultimate performance.  Accordingly, rural systems operators  could
significantly benefit from a system that provides greatly improved filtering and
very low noise amplification at reasonable cost.
 
    In  urban  areas, the  high density  of cellular  users creates  problems of
interference and system capacity. In every area, there are two cellular  service
providers, each allotted their own operating band within the frequency spectrum.
Near  the edges of each provider's operating frequency range, the performance of
cellular systems can be hampered by interference from the competing carrier  and
from  a variety  of other  signal sources.  Carriers can  attempt to  avoid this
interference by  not using  channels  at the  edges  of their  operating  bands,
however this diminishes system capacity. Interference is also addressed by using
highly  selective filters in  the base station receiver.  The ideal filter would
filter out  all signals  outside the  targeted operating  band without  reducing
signal  strength  inside the  band. Filters  are made  more selective  by adding
additional resonators or  "poles" to  the filter.  However, in  filters made  of
conventional  materials, adding additional poles introduces more energy loss and
thereby  reduces  the  strength  of  the  desired  signals.  For  this   reason,
conventional filters generally do not incorporate more than eight or nine poles,
thus  achieving  only  a  certain  level  of  selectivity.  With superconducting
materials, which exhibit extremely  low energy loss,  filters can be  fabricated
with a higher number of poles, thereby increasing filter selectivity.
 
    PCS  MARKET.   PCS is a  newer urban-based communication  system designed to
provide wireless  telephone  service  utilizing radio  frequency  signals  in  a
frequency  band near 2 GHz.  This all-digital system will  be designed to handle
both voice and data transmissions,  including features such as Internet  access.
Although  it utilizes the same  basic building blocks as  a cellular system, the
higher operating frequency of PCS compared with the cellular network limits  the
range  of  its signal  transmission.  Because of  this  limited range  of signal
transmission, based on information from third party sources Conductus  estimates
that  the forthcoming PCS buildout will result in more than 70,000 new installed
base stations throughout the U.S. by the end of the year 2005.
 
    The projected large number and primarily urban location of PCS base stations
drive the needs for equipment cost and size reduction. However, signal losses in
base station components such as filters, antennas and cables are exacerbated  by
higher  frequency operation. Conventional  receiver components limit sensitivity
and therefore base  station range.  Conventional filters tend  to be  physically
large  and proposed PCS base station architectures  call for the use of multiple
filters in each station. Collectively, these  issues present a difficult set  of
requirements for the designers of forthcoming PCS base station equipment.
 
    CONDUCTUS'  SOLUTIONS.  Conductus believes  that the performance of cellular
base stations and PCS base stations could be improved significantly by using HTS
components in both their receivers and their transmitters. Communication filters
made using thin-film  superconductor technology  have the  potential to  provide
extraordinary  frequency  selectivity  while  maintaining  excellent  efficiency
because of their inherent low insertion losses. On the receiver side, the use of
superconducting filters along with cryogenically-cooled low-noise amplifiers has
the potential to lower the noise figure of the receiver and thereby increase its
sensitivity. Increased sensitivity translates into increased range for the  base
station  which could be utilized to improve the performance of existing stations
or to allow fewer base stations to serve a new geographic area. In addition, HTS
filters with enhanced selectivity over conventional designs could  significantly
reduce signal interference in base station receivers with minimal signal loss.
 
    In  the cellular market,  Conductus is focusing  on development of low-noise
receiver subsystems  for  rural  base stations  that  incorporate  HTS  filters,
cryocooled  low-noise amplifiers and refrigeration equipment into a rack-mounted
package. Initial laboratory and field tests have demonstrated the ability of the
subsystem to increase receiver sensitivity, thereby increasing the range of base
stations as  well as  their overall  performance.  See table  on p.  27,  Target
Markets  and  Commercialization  Status.  As a  result,  by  using  these filter
systems, cellular service providers in rural environments may require fewer base
stations in order to serve a
 
                                       29
<PAGE>
given geographic area. Initial field  tests with these filter systems  completed
in  early 1996 show range  expansions of 20% to  60%. Conductus expects that the
subsystem will undergo  increasingly rigorous  testing during  1996, leading  to
potential  deliveries of  the first commercial  units for retrofit  use in rural
base stations in late 1996. While the Company has demonstrated functionality  in
its  prototype units,  additional engineering will  be required  to complete the
development of commercial communications subsystems. See "Risk Factors --  Early
Stage  of  the Superconductive  Electronics Market"  and "--  Limited Commercial
Manufacturing Capability."
 
    Base stations avoid the transmission of unwanted and interfering  distortion
signals  by the use of costly ultra-linear (extremely low distortion) amplifiers
in their  transmitters. For  the PCS  market, Conductus  believes that  low-loss
superconducting transmit filters offer the potential to "clean up" the output of
lower-quality amplifiers by removing unwanted signals at a lower overall cost to
the  base station operator. Conductus' work on  transmit filters has been a part
of the  activities of  the Consortium  for Superconductor  Electronics  wireless
program,  which primarily  involves Conductus, American  Telephone and Telegraph
Company, MIT  Lincoln  Laboratories  and CTI-Cryogenics,  a  division  of  Helix
Technology Corporation.
 
    Conductus  is developing  an integrated  transceiver subsystem  for PCS base
stations consisting  of  HTS receiver  filters,  cryogenically-cooled  low-noise
amplifiers  and  HTS transmit  filters  that potentially  may  provide increased
range, increased  call capacity,  reduced interference  between bands,  improved
call  quality  and  reduced  size  compared  to  subsystems  using  conventional
technology. Additionally,  the HTS  components utilized  in the  subsystem  have
permitted  the inclusion of  as many as 19  poles, compared to  eight or nine in
conventional filters,  which results  in significant  selectivity  enhancements.
Conductus  intends to work  with PCS system manufacturers,  such as Lucent, with
the goal  of  designing superconductive  filter  subsystems into  new  PCS  base
stations.  The first field test of  Conductus' initial prototype of the receiver
portion of  the system  has been  conducted with  Lucent. Conductus  expects  to
conduct   additional  tests  of  increasingly  complex  prototypes  with  Lucent
throughout 1996 and 1997 and does  not anticipate first commercial sales  before
late 1997 or early 1998.
 
    FUTURE   APPLICATIONS.    Pursuant   to  government-sponsored  research  and
development programs, Conductus is exploring the application of  superconductive
electronic  technology to problems  in high-speed, high-bandwidth communications
switching. The high-speed,  low-power properties of  Josephson junctions,  which
are  active switching  devices made  from superconductors,  could be  applied to
communications systems  to significantly  improve  data transmission  rates  and
reduce  system power  requirements and  costs. These  devices are  several times
faster than the fastest semiconductor transistor and consume thousands of  times
less  power. Josephson  junction circuit  technology is  in the  early stages of
development, and  significant additional  advancements will  be required  before
superconductive  products incorporating this  technology could become available.

    Instruments based on NMR technology  determine the structure and  properties
of chemical and biological materials by measuring the response of such materials
to  electromagnetic  fields. In  these  instruments, a  powerful  magnetic field
magnetizes atoms in the sample  being studied, radio-frequency pulses cause  the
atoms to emit characteristic signals and sensitive radio-frequency receivers are
used  to detect these  signals. Existing magnetic  resonance instruments contain
radio-frequency receivers that use specialized copper coils to sense the signals
from the  object  being  studied.  The principal  applications  of  NMR  are  in
spectrometers,  which are  used for analyzing  the composition  and structure of
complex chemical  compounds, and  in MRI  scanners, which  are used  to  provide
detailed  images of  the human body  without invasive procedures  or exposure to
harmful radiation, such as x-rays.
 
    For  both  of  these  instruments,  the  signal-to-noise  ratio   ultimately
determines  the sensitivity  of the  instrument. A  higher signal-to-noise ratio
results in better data quality and a reduction in the amount of time required to
obtain  the   data.  There   are  two   basic  approaches   to  increasing   the
signal-to-noise ratio of the
 
                                       30

instruments:  increasing the signal  or field strength by  using a more powerful
magnet, or increasing the sensitivity by  reducing inherent noise levels in  the
receiver. Increasing field strength can be prohibitively expensive. On the other
hand,  significant gains in receiver sensitivity  are difficult to achieve using
conventional technology.  HTS technology  offers  three potential  benefits  for
these  healthcare  imaging  and analysis  instruments:  much  greater instrument
sensitivity, much  faster  data  acquisition  time  and,  in  the  case  of  NMR
spectroscopy systems, the ability to study smaller amounts of costly samples.
 
    NMR  SPECTROMETERS.   NMR spectroscopy  is a  well-established technique for
chemical analysis that enables the user to determine the structures of even very
complex proteins and large  molecules such as those  used in the development  of
pharmaceuticals.  A  conventional  NMR spectrometer  includes  a superconducting
magnet to supply a  powerful magnetic field and  a copper or other  conventional
metal receiver coil to detect the signals from the sample.
 
    With conventional NMR technology, major increases in sensitivity can only be
obtained  with  disproportionate  increases in  cost  associated  with providing
increasingly powerful magnets.  Some large  magnet systems  cost as  much as  $1
million.  One alternative  to increasing the  field strength is  to increase the
sensitivity of the receiver.  However, conventional coil design  is at a  fairly
mature   stage  and   significant  further  improvements   in  sensitivity  from
modification of current receiver technology are unlikely. Another alternative is
to reduce the temperature of  conventional receiver components to near  absolute
zero,  in order to  reduce resistance and decrease  noise, but the refrigeration
necessary to  reach  the  required  temperatures  would  be  costlier  and  more
elaborate  than is needed for HTS probes. Such cold conventional metal receivers
have not been made commercially available.
 
    CONDUCTUS' SOLUTION.  Conductus has shown that the use of HTS receiver coils
in spectrometers  dramatically  improves  the  sensitivity  of  the  instrument.
Compared  to existing  receivers based  on specialized  copper coils, Conductus'
low-loss superconducting receiver coils significantly enhance probe  performance
by  improving the signal-to-noise ratio, which leads to either improved chemical
sensitivity or faster chemical measurements. As a result, users can examine less
sample material and still obtain the  same or more information than is  possible
using conventional technology. For this application, Conductus' probe technology
has  demonstrated  up  to a  four  fold signal-to-noise  ratio  improvement over
conventional probes enabling up to a four fold reduction in sample size for  the
same  analysis time or up to a  16-fold increase in sample throughput. Conductus
is currently working with Varian to develop a family of low-loss  superconductor
receiver  coils for use  as probes in  NMR spectrometers to  meet the demand for
high sensitivity analysis. Conductus introduced its first NMR probe products  in
March  1996, pursuant to an OEM arrangement with Varian. See table p. 27, Target
Markets and Commercialization Status. Currently, Conductus is manufacturing  and
selling  through Varian two NMR  probe types, each of  which is available in two
frequencies. The  Company anticipates  introducing a  third NMR  probe type  for
commercial  sale by the  end of 1996.  See "Risk Factors  -- Limited Outlets for
Certain Products",  "--  Competing  Technologies",  "--  Extensive  Reliance  on
Collaborative Relationships" and "-- Highly Regulated Product Applications."
 
    MRI.    Magnetic  resonance  imaging  is  an  important  diagnostic  medical
technique that provides detailed images of internal organs and structures within
the body without invasive procedures or exposure to harmful radiation. Important
applications include imaging soft tissues,  diagnosing certain brain and  spinal
cord  disorders  and  diagnosing joint  and  muscle  injuries. The  cost  of MRI
machines is  significant, with  prices  often over  $1 million.  More  recently,
"low-field"  and "mid-field" MRI machines  have become available. These machines
have the  advantage  of  being  less  confining to  the  patient  and  are  less
expensive,  but provide  significantly poorer  images than  high-field machines.
Government and healthcare provider cost containment initiatives are discouraging
the use of larger magnets for MRI. As cost controls have become more  pervasive,
the  majority  of  new  installations  have  been  of  less  costly, lower-field
machines.
 
    CONDUCTUS' SOLUTION.  Conductus has shown that the use of HTS receiver coils
can significantly improve the signal-to-noise  ratio in low-field MRI  machines,
potentially  allowing them to produce an image similar in quality to that of the
more  expensive  machines.  The  development  of  higher-performance   low-field
machines  may lead  to the  use of MRI  in a  wider range  of diagnostic imaging
applications, such  as routine  screening for  breast cancer.  In January  1996,
Conductus  entered  into  a  non-exclusive  agreement  with  Siemens  to develop
 
                                       31
<PAGE>
HTS receiver coil subsystems for a  Siemens' low-field MRI machine. The  Company
has  also received support from the Naval Research Laboratory and the Department
of  Defense  Advanced  Research  Projects  Agency  to  develop   superconducting
technology  for MRI  breast cancer  screening in  collaboration with researchers
from Stanford University.
 
    FUTURE  APPLICATIONS.    HTS  receiver   technology  can  be  used  in   NMR
microscopes,  which are  essentially high-resolution MRI  machines for examining
small objects in high  detail. Biological specimens  such as pathology  samples,
which are currently sliced, stained and examined with optical microscopes, could
be placed whole in the imager and a complete three-dimensional data set could be
constructed.  The pathologist  could have  the computer  slice the  image in any
plane, which is not  possible using the current  techniques, even with  computer
assistance,  because  of the  dramatic and  variable  shrinkage of  the samples.
Presently, NMR microscopy  is only  a research tool  because the  use of  copper
receiver coils can require data collection times of one to two days to obtain an
acceptable  image. The enhancement in signal-to-noise  ratio provided by HTS and
cryoelectronic technologies could reduce this  data collection time to a  matter
of  minutes. Conductus is developing receiver subsystems for this application in
collaboration with Duke  University under government  contract funding from  the
National  Institutes  of  Health.  See  "Risk  Factors  --  Early  Stage  of the
Superconductive Electronics Market."
 
  INSTRUMENTATION
 
    Superconductive magnetic  sensors known  as SQUIDs  are used  in  electronic
instruments to detect signals thousands of times smaller than can be detected by
conventional  magnetometers.  With appropriate  control electronics,  SQUIDs can
discern magnetic  signals one  hundred billion  times smaller  than the  earth's
magnetic   field.  A  number  of   different  types  of  instruments,  including
specialized laboratory  equipment, non-destructive  test equipment,  geophysical
surveying   instruments  and   advanced  medical   diagnostic  instruments,  can
potentially utilize magnetic sensors  to detect and  locate magnetic signals  of
interest.
 
    Magnetic  sensors are  used in  some circumstances  to locate  oil and other
mineral deposits. In this application, SQUID technology offers the advantage  of
portability  by  virtue of  the  small size  of  its sensors  compared  to bulky
conventional copper coils used as magnetometers. SQUID sensors can also be  used
to  detect electrical currents as well  as any intrinsic magnetism in materials.
As a result, they can potentially be used in a variety of instruments to inspect
and analyze materials and  structures on the basis  of magnetic signatures  that
cannot  be effectively measured using  competing technologies. These instruments
can measure materials  that are hidden  or submerged, such  as mines or  storage
drums;  detect flaws  in metallic structures,  such as  components of buildings,
nuclear power plants or airplanes, without physically invading or contacting the
structure; and  measure  electrical  currents  in,  for  example,  semiconductor
integrated circuits.
 
    SQUID  sensors can also detect electrical  impulses in the heart without the
use of electrodes  or other  contacts to  the patient  required by  conventional
EKGs,  using a technique called  magnetocardiography ("MCG"). Conductus believes
that MCG potentially may require far less time and effort from medical personnel
than electrocardiography  and therefore  reduce the  cost of  obtaining  cardiac
diagnostic  information. For example, MCG  could become a significant diagnostic
tool for disorders caused by cardiac arrhythmias (i.e., irregular heart beats).
 
    Improving the sensitivity of magnetic sensor technology in general, as  well
as  providing HTS versions of SQUID sensors  in particular, has the potential to
significantly improve the performance of several existing instruments as well as
enable magnetic sensing technology to be used for important new applications.
 
    CONDUCTUS' SOLUTION.  Conductus currently manufactures and sells SQUIDs  and
laboratory  instruments  based  on  SQUIDs and  is  developing  additional SQUID
sensors, electronics  and  complete  sensing subsystems  for  customers  in  the
geophysical,  non-destructive evaluation and  medical markets. See  table p. 27,
Target  Markets  and  Commercialization  Status.  Conductus'  standard  products
include  magnetic sensing components  sold under the  tradenames "iMAG" and "Mr.
SQUID" and a complete magnetometer system sold under the tradename "xMAG."  List
prices   for   complete   iMAG   systems   generally   range   from   $7,000  to
 
                                       32
<PAGE>
over $40,000  depending on  the configuration.  Mr. SQUID  has a  list price  of
approximately $2,000. List prices for complete xMAG systems generally range from
$87,000 to over $140,000 depending on the configuration.
 
    Conductus  has also  built and sold  limited numbers  of custom multichannel
low-temperature superconducting ("LTS") SQUID  systems for non-destructive  test
applications.  While Conductus manufactures some of its instrumentation products
using well-established LTS  materials, the  Company believes that  the cost  and
operating  difficulties  associated with  using liquid  helium or  other complex
refrigeration techniques  required  to cool  LTS  materials have  limited  their
commercial  potential. Conductus believes that the portability and relative ease
of use inherent in HTS SQUID technology greatly enhances its utility in multiple
applications.
 
    While historically the  Company's sales  have been  primarily to  laboratory
customers, Conductus believes that the greatest opportunities for growth for its
magnetic  sensing products will be with OEM customers for specific applications.
Currently, Conductus  is developing  HTS  geophysical systems  under  government
contracts  from two different  agencies and is working  with Geometrics, Inc., a
manufacturer  of  geophysical  surveying   equipment,  to  develop  and   market
commercial  instruments for these  applications. Conductus is  also working with
researchers at Kanazawa Institute of Technology in Japan to develop  SQUID-based
instruments  for seismic studies.  Conductus has also  sold sensors, electronics
and cryogenic vessels to customers developing biomedical applications of SQUIDs.
See "Risk Factors -- Early Stage of the Superconductive Electronics Market", "--
Dependence  on   Licensed  Technology"   and   "--  Highly   Regulated   Product
Applications."
 
    The  field  of  superconductivity  is  characterized  by  rapidly  advancing
technology. The future success of the Company will depend in large part upon its
ability to  keep  pace  with  advancing  superconductive  technology,  including
superconducting materials and processes, and industry standards. The Company has
focused  its development  efforts to date  principally on  yttrium barium copper
oxide ("YBCO").  There can  be  no assurance  that  YBCO will  ultimately  prove
commercially  competitive against  other currently known  materials or materials
that may be  discovered in  the future.  The Company  will have  to continue  to
develop  and integrate advances in technology  for the fabrication of electronic
circuits and devices and manufacture  of commercial quantities of its  products.
The  Company will  also need  to continue to  develop and  integrate advances in
complementary technologies.  There  can  be  no  assurance  that  the  Company's
development  efforts  will  not be  rendered  obsolete by  research  efforts and
technological advances  made  by  others  or that  materials  other  than  those
currently   used  by  Conductus  will  not   prove  more  advantageous  for  the
commercialization of superconductive electronic  products. In addition, many  of
Conductus'  potential products, if successfully developed, are likely to be used
as components or  subsystems in  systems manufactured  and sold  by third  party
systems  manufacturers. There can be no  assurance that these third parties will
elect to incorporate superconductive electronic products in these systems or, if
they do, that related system requirements, such as data processing software  and
hardware  capabilities, can or will be  successfully developed. Failure of third
parties  to  successfully   commercialize  complementary   technologies  or   to
incorporate  the Company's  products into  their systems  would have  a material
adverse  effect  on  Conductus'   business,  operating  results  and   financial
condition.
 
STRATEGIC ALLIANCES AND DEVELOPMENT AGREEMENTS
 
    Conductus   is  party  to  a   number  of  collaborative  arrangements  with
corporations and research institutions with respect to the research, development
and marketing of certain of its  potential products. Conductus evaluates, on  an
ongoing  basis, potential collaborative relationships and intends to continue to
pursue  such   relationships.  The   Company's   future  success   will   depend
significantly on its collaborative arrangements with third parties. There can be
no  assurance  that these  arrangements will  result in  commercially successful
products.  See   "Risk   Factors   --  Extensive   Reliance   on   Collaborative
Relationships," and "-- Limited Outlets for Certain Products."
 
    LUCENT  TECHNOLOGIES,  INC.    Conductus and  Lucent  entered  into  a joint
development and  licensing agreement  in April  1996, under  which Conductus  is
developing  a superconductive transceiver  filter subsystem for  the PCS market.
Both Conductus  and Lucent  are to  provide technical  support to  the  program.
Initial
 
                                       33
<PAGE>
tests  of a prototype of the receiver portion of the subsystem were conducted in
April 1996.  Each party  will  retain rights  to  the intellectual  property  it
develops  under the program, subject to certain nonexclusive licensing rights of
the other party,  and jointly  developed intellectual property  will be  jointly
owned.
 
    VARIAN  ASSOCIATES.  Conductus  and Varian entered  into a joint development
and  licensing  agreement  in  1994,  under  which  they  jointly  developed   a
superconducting probe for NMR instruments for high-resolution spectroscopy. Both
Conductus and Varian provided technical support to the program, and each retains
rights  to  intellectual property  it developed  under  the program,  subject to
certain nonexclusive licensing rights of  the other party. The program  resulted
in  the  commercial introduction,  in March  1996,  of probes  incorporating HTS
receiver subsystems manufactured by  the Company and  sold by Varian.  Conductus
and  Varian currently are negotiating a  sales agreement under which Varian will
likely have a period  of exclusivity from the  date of commercial  introduction.
Conductus  and Varian  continue to  cooperate in  the development  of additional
probes for NMR spectroscopy.
 
    SIEMENS AG.  Conductus is  developing a general-purpose superconducting  MRI
receiver  coil for  a Siemens'  low-field MRI  system under  a joint development
agreement effective  December  1, 1995.  Under  that agreement,  Conductus  will
design  a coil and  test it on  Siemens' instruments, while  Siemens will assist
Conductus  by  providing   information  and  access   to  instrumentation.   All
intellectual   property  rights  will  remain  with  the  party  developing  the
intellectual property, and jointly developed property will be jointly owned.
 
    CTI-CRYOGENICS.    Conductus  and   CTI-Cryogenics,  a  division  of   Helix
Technology  Corporation,  entered into  a  collaboration agreement  in September
1995, under which CTI will work with Conductus to design interfaces between  CTI
cryocoolers and Conductus subsystems.
 
    HIGH-TEMPERATURE SUPERCONDUCTOR THIN-FILM MANUFACTURING ALLIANCE.  Conductus
is  a principal member of the HTMA, which was formed in November 1995 to develop
cost-effective manufacturing  methods for  YBCO thin-films  for  radio-frequency
applications,  establish  industry  standards  and  provide  second-sourcing and
technology transfer among the companies under a program currently funded in part
by the  Department  of  Defense Advanced  Research  Projects  Agency  ("DARPA").
Superconductor  Technologies, Inc. ("STI") is the  other principal member of the
HTMA. Other  members  include  Stanford  University  and  the  Georgia  Research
Corporation, Focused Research, Microelectronic Control and Sensing Incorporated,
IBIS and BDM Federal. Under the HTMA, each party will have certain access to the
technology of the other parties that is developed under the program.
 
    KANAZAWA INSTITUTE OF TECHNOLOGY.  In September 1995, Conductus entered into
an  OEM  agreement with  Kanazawa Institute  of  Technology ("KIT")  under which
Conductus is to be KIT's exclusive  supplier, subject to certain conditions,  of
LTS  and HTS SQUIDs  for use in  instruments that it  is developing. KIT intends
that its  initial product  will be  for seismology.  Conductus has  received  an
initial  order for  LTS SQUIDs under  this agreement. The  agreement contains no
minimum purchase  requirement, and  there  can be  no  assurance that  KIT  will
successfully  develop and market instruments using Conductus' SQUID products or,
if it does develop such products, that a significant market will exist for those
products. Futhermore, there can be no  assurance that Conductus will be able  to
meet  KIT's design requirements,  in which case  KIT shall be  free to use other
suppliers of SQUIDs.
 
    GEOMETRICS.   Conductus  is working  with  Geometrics, Inc.,  a  geophysical
instrumentation  company, under two government  contracts to develop SQUID-based
instruments for geophysical exploration. If  successful, the project could  lead
to the development of commercial geophysical instruments incorporating Conductus
SQUIDs and SQUID electronics.
 
RESEARCH AND DEVELOPMENT
 
   
    GOVERNMENT  CONTRACTS.  The  Company's research and  development expenses in
the three months ended March 31, 1996, and fiscal years 1995, 1994 and 1993 were
approximately $2,743,000, $9,819,000,  $9,201,000 and $7,080,000,  respectively.
Externally  funded research and development  programs, primarily under contracts
with agencies of  the U.S. government,  accounted for approximately  $2,855,000,
$9,176,000,
    
 
                                       34
<PAGE>
$8,717,000  and $6,500,000 of these expenses in the three months ended March 31,
1996, and fiscal years 1995, 1994 and 1993, respectively. The Company's  revenue
from  government-related contracts  represented approximately 85%,  77%, 82% and
78% of total revenue for the three months ended March 31, 1996 and fiscal  years
1995,  1994 and 1993, respectively. Conductus  believes that it will continue to
be heavily dependent on U.S. government contracts to fund a significant  portion
of  its research and development  programs. The Company's strategy  is to fund a
significant portion of its research  and development, particularly for  wireless
communications  and  digital  electronics applications,  through  contracts with
agencies of the U.S. government. As of March 31, 1996, the Company had  received
aggregate  awards  since its  inception of  approximately $36,652,000  from U.S.
government agencies, including approximately  $25,529,000 recognized as  revenue
by  the Company through  March 31, 1996, and  approximately $7,760,000 in awards
for which it has not yet entered into research contracts. As of March 31,  1996,
Conductus  had approximately $3,364,000 under existing U.S. government contracts
which provide that most of  the research and development  is to be performed  in
the  next  12 months.  See "Management's  Discussion  and Analysis  of Financial
Condition and Results of Operations -- Results of Operations."
 
    As shown in the  examples below, these contract  programs and others  enable
Conductus  to  develop its  core  technologies and  support  Conductus' business
areas.

    The Company's contracts involving the U.S. government are or may be  subject
to   numerous  risks.  These  risks  include:  unilateral  termination  for  the
convenience of the government; reduction or modification in the event of changes
in  the  government's  requirements  or  budgetary  constraints;  increased   or
unexpected  costs causing losses or  reduced profits under fixed-price contracts
or unallowable  costs under  cost reimbursement  contracts; risks  of  potential
disclosure  of Conductus' confidential information to third parties; the failure
or  inability  of  the  prime  contractor  to  perform  its  prime  contract  in
circumstances where Conductus is a sub-contractor; the failure of the government
to   exercise  options   provided  for   in  the   contracts;  the  government's
nonexclusive, royalty-free license to use  technology developed pursuant to  the
contracts  by  or on  behalf  of the  government  in certain  circumstances; and
exercise of "march-in" rights  by the government. March-in  rights refer to  the

there can be no assurance that the U.S. government will continue its  commitment
to  programs  to  which  the  Company's  development  projects  are  applicable,
particularly in light of recent legislative initiatives to reduce the funding of
various U.S. government agencies and programs,  or that the Company can  compete

    SCIENTIFIC ADVISORY BOARD.   Since its founding,  Conductus has engaged  the
services  of a Scientific Advisory Board  composed of experts in superconducting
materials, devices  and  science who  advise  the Company  concerning  long-term
scientific  planning, research  and development.  The members  of the Scientific
Advisory Board  provide  research,  investigation  and  consulting  services  to
Conductus  in exchange  for consulting fees.  Seven members  have had consulting
agreements with the Company since 1987 and have equity ownership in the  Company
as a result of option grants.
 
    The  Scientific  Advisory  Board  is  chaired by  Dr.  John  M.  Rowell, who
previously served as the  Chief Technical Officer of  Conductus from 1988  until
August 1995. Dr. Rowell has been a leading figure in superconductive electronics
for  over 30  years. The  membership of  the Scientific  Advisory Board includes
Professor  Malcolm  R.  Beasley,   Stanford  University;  Dr.  Leonard   Cutler,
Hewlett-Packard  Company;  Dr.  Robert  C. Dynes,  Chancellor  of  University of
California,  San  Diego;  Professor  John  Clarke,  University  of   California,
Berkeley;  Professor  Emeritus  Theodore H.  Geballe,  Stanford  University; Dr.
Robert H. Hammond,  Stanford University; Professor  Aharon Kapitulnik,  Stanford
University;  Professor Paul L. Richards, University of California, Berkeley; and
Professor Theodore  Van Duzer,  University of  California, Berkeley.  See  "Risk
Factors -- Attraction and Retention of Key Employees."
 
PATENTS, PROPRIETARY TECHNOLOGY AND TRADEMARKS
 
    Conductus  has received 17 U.S. patents and one related foreign patent which
have unexpired terms ranging from 13 to 18 years and has 18 patent  applications
pending  before the U.S. Patent and Trademark  Office. One of those patents, for
an MRI coil,  is currently involved  in an interference  proceeding in the  U.S.
Patent and Trademark Office. See "Legal Proceedings." International counterparts
of several of these pending applications or issued patents have been filed under
the Patent Cooperation Treaty with a number of applications currently pending in
various  countries  worldwide.  These  patents  and  patent  applications  cover
Conductus processes and products  in many aspects of  its business. The  Company
will  continue to file  other U.S. and key  international patent applications as
part of its business  strategy to protect technology  it considers important  to
providing  a competitive market advantage for  its technologies. There can be no
assurance, however, that its  applications will result  in issued patents,  that
the  validity of  its issued patents  will not  be subject to  challenge or that
third parties will  not be able  to design  around the patented  aspects of  the
Company's  products.  The Company  also  relies upon  trade  secrets, unpatented
know-how,  continuing   technological  innovation,   employee  and   third-party
nondisclosure  agreements and the pursuit of licensing opportunities in order to
develop and maintain its competitive position. The Company's efforts to  protect
its  proprietary rights may not be successful, prevent their misappropriation or
ensure that these rights will provide the Company with a competitive  advantage.
Additionally,  certain of the issued patents and patent applications are jointly
owned by the  Company and  third parties.  Any party  has the  right to  license
rights  under such patents and applications, which could result in Conductus not
having exclusive control over such inventions.
 
    The Company  believes that,  since the  discovery of  HTS in  1986,  several
thousand  patent  applications have  been filed  worldwide  and over  a thousand
patents have been granted in the  U.S. relating to superconductivity. There  are
interference  proceedings pending regarding rights to inventions claimed in some
of the applications. Accordingly,  the patent positions  of companies using  HTS
technology,  including Conductus, are  uncertain and involve  both complex legal
and factual  questions. Consequently,  there is  significant risk  that  others,
including  competitors  of the  Company, have  obtained  or will  obtain patents
relating to the Company's planned products or technology.
 
    A patent issue  of particular importance  to the Company  relates to  copper
oxides  or  "cuprates," that  are  used to  make  HTS products,  including YBCO.
Conductus has neither obtained  any issued patents nor  has it filed any  patent
applications  covering the composition  of any cuprates  or other HTS materials.
However, several U.S.  and foreign patent  applications, including  applications
filed by IBM, AT&T, the University of Houston, the Naval Research Laboratory and
others,  are pending  that cover  the composition of  YBCO and  related HTS. See
"Business -- Background -- Conductus' Approach." The Company understands that at
least several  of such  U.S. applications  are the  subject of  an  interference
proceeding   currently  pending  in   the  U.S.  Patent   and  Trademark  Office
(Interference No.  101,981).  Additionally, E.  I.  du  Pont de  Nemours  &  Co.

("DuPont")  has notified Conductus that it  is the exclusive licensee of patents
issued in Israel, Sweden, Taiwan and the United Kingdom covering the composition
of YBCO and a method for using YBCO in superconducting applications. Dupont  has
stated  that it  is interested  in sublicensing  such patents  to Conductus, and
would consider sublicensing to Conductus, as  they issue, any other foreign  and
U.S.  patent applications licensed  to DuPont by the  University of Houston. The
Company anticipates that it  will be required  to obtain a  license to use  YBCO
from  one or  more of  these parties in  order to  continue to  develop and sell
products based on YBCO.
 
    There can be no assurance that the Company would able to obtain licenses  to
patents  covering  YBCO  compositions,  when issued,  or  to  any  other patents
applicable to the Company's business  on commercially reasonable terms. In  such
an  event,  the Company  could be  required to  expend significant  resources to
develop non-infringing  technology alternatives  or to  obtain licenses  to  the
technology  that  the  Company infringes  or  would  infringe. There  can  be no
assurance that the  Company would be  able to successfully  design around  these
third  party patents or  to obtain licenses  to technology that  it may require.
Furthermore, there can be no assurance that the Company will not be obligated to
defend itself at substantial cost  against allegations of infringement of  third
party  patents. An adverse outcome  in such a suit  could subject the Company to
significant liabilities to third parties, or require the Company to cease  using
such  technology. In  addition, aside from  the merits  of a claim,  the cost of
defending any  such suit  would  constitute a  major  financial burden  for  the
Company  that would  have a material  adverse effect on  its business, operating
results and financial condition. See "Risk Factors -- Uncertainty of Patents and
Proprietary Rights; Risk of Litigation."
 
    Conductus has  granted to  various entities  non-exclusive,  royalty-bearing
licenses  to  certain  of its  proprietary  technology for  the  manufacture and
distribution of various equipment, including rotating target holders,  substrate
heaters  and  mutual  inductance  probes to  be  used  in  cryogenic measurement
systems. Through its strategic relationships,  Conductus has received rights  to
certain  intellectual property developed by its partners, as well as commitments
from  those  partners  to  offer  licenses  to  certain  background  technology.
Conductus  cannot, however, be certain that such  licenses will be on terms that
allow Conductus to compete effectively in the marketplace. See "Risk Factors  --
Uncertainty of Patents and Proprietary Rights; Risk of Litigation."
 
    Additionally,  successful  marketing  of a  material  portion  of Conductus'
products  depends  in  part  on  nonexclusive  licenses  obtained  from  various
licensors.  There can be no assurance that  such licenses will not be terminated
by licensors or that Conductus will  be able to develop alternate products  that
do not require these or other licenses.
 
    Conductus  owns  the United  States  registered trademarks  "CONDUCTUS," the
Conductus logo, "Mr. SQUID"  and "iMAG" and claims  the rights to the  trademark

MANUFACTURING
 
    Conductus   has  performed  pioneering  work  in  materials,  processes  and
structures based  on thin-film  superconducting  technology, and  has  developed
processes   it  believes  are  capable  of  routinely  producing  a  variety  of
high-quality films  for  several applications,  including  multilayer  thin-film
materials  suitable  for  more  complex devices  and  components.  Conductus has
established a  pilot  production  facility at  its  headquarters  in  Sunnyvale,
California  to  fabricate,  test  and  assemble  HTS  and  LTS  thin  films  and
components. The  Company fabricates  two-, three-  and four-inch  wafers in  two
cleanroom  areas that consist,  in the aggregate,  of approximately 2,600 square
feet and that have ratings of subclass 1,000 and 10,000 (meaning there are fewer
than 1,000 or 10,000 particles larger than  0.5 microns per cubic foot of  air).
See  "Business --  Properties." Conductus  combines what  it believes  to be the
world's most advanced YBCO thin-film technology with expertise in electronic and
device component design,  analog and digital  electronic engineering,  cryogenic
packaging, mechanical engineering and system integration.
 
    The  primary  materials and  equipment used  in Conductus'  products include
substrates, YBCO and processing equipment.  The Company procures its  substrates
from  several suppliers. The Company procures  its YBCO source material from two
suppliers  and  believes  that   YBCO  can  be  obtained   from  at  least   two
 
                                       37
<PAGE>
other  vendors.  For  certain  processes,  Conductus  utilizes  elemental metals
(yttrium, barium and  copper) to  produce YBCO. These  substances are  available
from  numerous  vendors. The  Company's processing  equipment is  assembled from
off-the-shelf components which can be obtained from multiple sources.
 
    Conductus believes  that most  of its  products for  the communications  and
healthcare   markets  will  be  in  the  form  of  subsystems  that  incorporate
superconducting and cryoelectronic components  with cryogenic refrigerators  and
conventional  electronic assemblies.  Apart from  the superconducting components
which are manufactured  by Conductus,  the Company anticipates  that most  other
components  of  its  subsystems  will be  purchased  as  standard  products from
commercial vendors or  specially ordered from  various suppliers. These  include
cryogenic  refrigerators, printed  circuit boards,  product cases  and housings,
vacuum  vessels  and   other  components.  Certain   components  of   Conductus'
subsystems,  including cryocoolers, are currently  obtained from a single source
or a limited number of suppliers. Although the Company does not believe that  it
is  ultimately dependent upon any supplier of  these components as a sole source
or limited source for any critical  components, the inability of the Company  to
develop  alternative  sources,  if  required, an  inability  to  meet  demand, a
prolonged interruption in supply  or a significant increase  in price of one  or
more  components would have a material adverse effect on the Company's business,
operating results and financial condition. See  "Risk Factors -- High Degree  of
Dependence  Upon Other Complementary Technologies"  and "-- Reliance on Limited-
or Sole-Source Suppliers."
 
    Conductus is focusing on the development of its production processes and  is
manufacturing limited quantities of superconducting components and prototypes at
its Sunnyvale, California facility. Apart from the production of superconducting
components,  the Company's manufacturing activities generally will be limited to
cleaning, final  assembly,  vacuum bakeout  and  test procedures.  Conductus  is
producing  these products in limited commercial  quantities and is continuing to
expand its capabilities. See "Risk  Factors -- Limited Commercial  Manufacturing
Capability."  At its Instrument  and Systems Division  in San Diego, California,
Conductus designs and manufactures large-scale superconductive magnetic  sensing
systems  using these superconductive components.  This facility also designs and
manufactures electronic  instruments  and  circuitry used  in  conjunction  with
superconductive components.
 
COMPETITION
 
    Although  the market for superconductive  electronics currently is small and
in the early stages of development,  Conductus believes this market will  become
intensely   competitive  if  products  with  significant  market  potential  are
successfully developed.
 
    A number of large American, Japanese  and European companies are engaged  in
research  and development programs  that the Company believes  could lead to the
development and/or  commercialization  of superconductive  electronic  products.
These  include, among others: DuPont, IBM, TRW, and Northrop-Grumman Corporation
in the U.S.;  and Fujitsu Ltd.,  Hitachi Ltd., NEC  Corp. and Sumitomo  Electric
Industries,  Ltd. in Japan. The  Company also believes that  a number of smaller
companies  are   engaged   in   various   aspects   of   the   development   and
commercialization  of superconductive electronics products. These include, among
others, Biomagnetic  Technology,  Inc.  and Quantum  Design,  Inc.  in  magnetic
sensing products; Hypres, Inc. in digital circuits; and Illinois Superconducting
Corp.,  Superconducting Core Technologies,  Inc. and Superconductor Technologies
Inc.   in   wireless   communications.   Furthermore,   academic   institutions,
governmental  agencies and other  public and private  research organizations are
engaged in development programs which  may lead to competitive arrangements  for
commercializing  superconductive  electronics  products.  In  addition,  if  the
superconductor industry does develop further, new competitors with significantly
greater resources are likely to enter  the field. Conductus' ability to  compete
successfully  will require it  to develop and  maintain technologically advanced
products, attract and retain highly qualified personnel, obtain patent or  other
protection  for  its  technology and  products  and manufacture  and  market its
products, either  alone or  with third  parties. See  "Risk Factors  --  Intense
Competition."
 
    The   Company's  existing  collaborative  arrangements  permit,  and  future
arrangements also may permit, the Company and each partner to use the technology
developed under these  arrangements. Accordingly, the  Company may compete  with
its  partners  for  commercial  sales  of  any  products  developed  under these
arrangements.
 
                                       38
<PAGE>
    The Company's  potential products,  if successfully  developed, may  compete
directly   with  other  existing  and   subsequently  developed  products  using
competitive, conventional  technologies.  There can  be  no assurance  that  the
Company's  products will have sufficient performance advantages over these other
products to attract significant commercial  interest. These and related  factors
may   limit   market  acceptance   of  products   incorporating  superconductive
technology. See "Risk Factors -- Competing Technologies."
 
    Conductus believes that the principal competitive factors in the market  for
superconductive  electronics  will  be  the following:  the  ability  to develop
commercial applications  of  superconductive  technology;  product  performance,
including,  where appropriate,  speed, sensitivity, size  and power dissipation;
price; product quality and reputation. Conductus believes that it is competitive
with  respect   to  these   factors.  Nonetheless,   because  the   market   for
superconductive  electronics  is at  an  early stage,  the  relative competitive
position of the Company in the future is difficult to predict.
 
SALES AND MARKETING
 
    Although  Conductus  has   limited  experience  in   sales,  marketing   and
distribution,  it has been expanding its expertise and activities in these areas
in order to successfully commercialize  its potential products. Conductus  sells
its  products through  a combination  of OEM  relationships, direct  sales and a
network of  independent  manufacturer's representatives  and  distributors.  The
Company's  sales and marketing strategy is to use manufacturers' representatives
and  distributors  for  sales  of  its  magnetic  sensor-based  and   laboratory
instrument products and to rely primarily on OEMs for its subsystem products for
communications,  healthcare and  instrumentation. The Company  has established a
domestic and international network of independent manufacturer's representatives
who have  primary responsibility  for selling  magnetic sensing  and  laboratory
instrumentation  products. As of March 31, 1996, 11 domestic and 8 foreign firms
were manufacturer's representatives and distributors, covering 41 states and  18
foreign  countries including a majority of western Europe, Japan, Australia, New
Zealand and  India. See  "Risk  Factors --  Need  to Develop  Infrastructure  to
Support Commercialization."
 
    The  Company currently employs a sales and marketing staff of nine full-time
equivalents. These employees are actively engaged in direct marketing to OEM and
potential OEM customers, as well as in sales and marketing support. The  Company
actively  markets its products through advertisements  in trade journals as well
as through demonstration of its technology and products at industry trade shows,
including trade  shows  related  to telecommunications,  NMR  spectroscopy,  MRI
imaging and magnetic sensing. The Company's employees have published the results
of  their  research  at  Conductus  widely  in  trade  and  technical  journals.
Additionally,  Conductus'   employees  have   frequently  presented   Conductus'
technology as invited speakers at conferences worldwide.
 
    For  the three months ended  March 31, 1996 and  fiscal years 1995, 1994 and
1993, commercial sales  to one  customer of $241,000,  $1,172,000, $732,000  and
$816,000 were 9%, 11%, 8% and 13% of total revenues, respectively. This customer
acts primarily as a distributor of the Company's products, selling to end-users.
 
ENVIRONMENTAL MATTERS
 
    The   Company  uses  certain   hazardous  materials  in   its  research  and
manufacturing operations. As a  result, Conductus is  subject to federal,  state
and local governmental regulations. Conductus believes that it has complied with
all regulations and has all permits necessary to conduct its business. See "Risk
Factors -- Environmental Regulations."

PROPERTIES
 
    The  Company's principal facility, including  its pilot production facility,
is located  in  two buildings  providing  approximately 40,000  square  feet  of
available  space in Sunnyvale, California. In  November 1994, the Company signed
new leases  on  both  buildings which  will  expire  in August  2000  and  2001,
respectively.  The increase in space will facilitate expansion for manufacturing
and development efforts. Conductus also leases approximately 10,000 square  feet
in  San Diego, California under a lease  expiring in 1998 for its Instrument and
Systems Division. The Company believes its existing facilities are adequate  and
suitable  for  its  current  needs,  and additional  space  can  be  obtained on
commercially reasonable terms as needed to expand the Company's operations.
 
LEGAL PROCEEDINGS
 
    One  Conductus  patent  covering  technology  related  to  certain  magnetic
resonance  probe coils is currently subject to an interference proceeding with a
competitor, Superconductor Technologies, Inc.,  before the Patent and  Trademark
Office.  Based on  the Company's current  product development  plan, the Company
does not  believe that  an adverse  resolution of  the proceeding  would have  a
material   adverse  effect  on  its  business  operating  results  or  financial
condition. The Company  is not a  party to  any material litigation  and is  not
aware  of any  pending or threatened  litigation against the  Company that could
have a material adverse effect upon the Company's business, operating results or
financial condition. See "Risk Factors -- Uncertainty of Patents and Proprietary
Rights; Risk of Litigation."
 
EMPLOYEES
 
    As of March 31, 1996,  the Company had a  total of 105 full-time  equivalent
employees  of which 46 hold advanced  degrees. Of the total full-time employees,
65 were engaged in research and  product development, 11 in manufacturing,  nine
in  sales  and  marketing, three  in  operations  and 17  in  administration and
finance. None of the  Company's employees is represented  by a labor union.  The
Company  has not experienced any work stoppages and considers its relations with
its employees to be good.

- ------------------------
(1)  The options granted to Dr. Simon and Mr. Tamblyn are immediately subject to
    a right of repurchase in  favor of the Company  that lapses as follows:  20%
    upon  the completion of the  first year of service  measured from January 1,
    1995 and an additional  1.67% upon the completion  of each month of  service
    elapsed  thereafter,  until  the  option  shall  be  fully  vested  upon the
    completion of the fifth year of  service from the vesting date. The  options
    were granted January 24, 1995, and began vesting on January 1, 1995.
 
(2)  The exercise price may be paid in cash, in shares of Common Stock valued at
    fair market  value on  the  exercise date  or  through a  cashless  exercise
    procedure involving a same-day sale of the purchased shares. The Company may
    also finance the option exercise by loaning the optionee sufficient funds to
    pay  the exercise price for  the purchased shares and  the federal and state
    income tax  liability  incurred by  the  optionee in  connection  with  such
    exercise.  The  Compensation Committee  has  the discretionary  authority to
    reprice outstanding options  through the cancellation  of those options  and
    the  grant of replacement options with an  exercise price equal to the lower
    fair market value of the option shares on the regrant date.
 
(3) The 5% and 10% assumed  annual rates of compounded stock price  appreciation
    are mandated by rules of the Securities and Exchange Commission. There is no
    assurance  provided  to any  executive officer  or any  other holder  of the
    Company's securities  that  the actual  stock  price appreciation  over  the
    10-year option term will be at the assumed 5% and 10% levels or at any other
    defined  level. Unless the market price of the Common Stock appreciates over
    the option term, no value  will be realized from  the option grants made  to
    the executive officers.

    shares purchased  under the  option will  be subject  to repurchase  by  the
    Company,  at  the original  exercise price  per  share, upon  the optionee's
    cessation of service  prior to vesting  in such shares.  As of December  31,
    1995,  the  Company's  repurchase  right  had  lapsed  with  respect  to the
    following number of option shares: Mr.  Shalvoy -- 69,998; Mr. MacMillan  --
    28,333; Dr. Simon -- 33,806; and Mr. Tamblyn -- 13,666.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    John  F. Shoch,  who became  a member of  the Compensation  Committee of the
Board of Directors in May 1993, is  a general partner of AMC Partners 84,  which
is the general partner of Asset Management Associates 1984, the beneficial owner
of  more  than 5%  of  the Company's  Common Stock.  Dr.  Shoch served  as Chief
Executive Officer of the Company from September 1987 until October 1988.
 
    For information concerning grants of options to certain non-employee members
of the Board  of Directors, including  Dr. Shoch and  Mr. McKenna, see  "Certain
Transactions -- Option Grants."
 
    The  Company has entered  into separate indemnification  agreements with its
directors and  officers.  These  agreements require  the  Company,  among  other
things,  to indemnify them against certain  liabilities that may arise by reason
of their  status  or service  as  directors or  officers  and to  advance  their
expenses  incurred as a result  of any proceeding against  them as to which they
could be indemnified.
 
EMPLOYMENT CONTRACTS
 
    None of the  Company's executive  officers (other than  Charles E.  Shalvoy)
have  employment  agreements  with  the Company,  and  their  employment  may be
terminated at any time at the discretion of the Board. The Company entered  into
an  agreement  with Mr.  Shalvoy, the  Company's  President and  Chief Executive
Officer, on May 3,  1994, which provides for  accelerated vesting of his  option
shares  as if he remained employed for one additional year in the event that his
employment is terminated without  cause following certain mergers,  acquisitions
or  sales of all  or substantially all of  the assets of  the Company. Under the
1992 Stock Option/Stock Issuance Plan (the "1992 Plan"), upon the occurrence  of
a  merger, reverse merger or  sale of all or substantially  all of the assets of
the Company, outstanding  options held by  the Chief Executive  Officer and  the
Company's  other  executive officers  will automatically  accelerate and  may be
exercised as  fully  vested shares,  unless  such  options are  assumed  by  the
successor corporation. In addition, the Compensation Committee has the authority
as Plan Administrator of the 1992 Plan to provide for the accelerated vesting of
the  shares of  Common Stock  subject to outstanding  options held  by the Chief
Executive Officer and  the Company's other  executive officers, whether  granted
under that plan or any

predecessor plan, in the event that a Change in Control (as hereinafter defined)
occurs  or in  the event  that their employment  were to  be terminated (whether
involuntarily or through a forced resignation) following a Change in Control.  A
Change  in  Control is  a hostile  takeover  of the  Company effected  through a
successful tender offer for  more than 50% of  the Company's outstanding  Common
Stock  or through a change  in the majority of  the Board as a  result of one or
more contested elections for Board membership.
 
1992 STOCK OPTION/STOCK ISSUANCE PLAN
 
    The Company's 1992 Stock  Option/Stock Issuance Plan  (the "1992 Plan")  was
adopted  by the  Board of  Directors on  January 11,  1992, and  approved by the
stockholders on April 25, 1992  as the successor to  the 1987 Stock Option  Plan
and 1989 Stock Option Plan ("Predecessor Plans"). The 1992 Plan has been amended
on  numerous occasions, most recently in January  1996 to increase the number of
shares issuable  under  the  1992  Plan. The  January  1996  amendment  received
stockholder  approval  at  the 1996  annual  meeting  in May  1996.  A  total of
1,880,000 shares of  Common Stock have  been authorized for  issuance under  the
1992  Plan. As of March 31, 1996, 310,784  shares had been issued under the 1992
Plan,  options  for  1,157,026   shares  were  outstanding  (including   options
incorporated  from the Predecessor Plans)  and 412,190 shares remained available
for future  grant.  Shares  of  Common Stock  subject  to  outstanding  options,
including options granted under the Predecessor Plans, which expire or terminate
prior to exercise will be available for future issuance under the 1992 Plan.
 
    The   1992  Plan  is  divided  into   three  separate  components:  (i)  the
Discretionary  Option  Grant  Program  under  which  key  employees   (including
officers)  and  independent  consultants  may, at  the  discretion  of  the Plan
Administrator, be  granted options  to purchase  shares of  Common Stock  at  an
exercise  price per share  not less than 85%  of fair market  value on the grant
date, (ii) the Stock Issuance Program  under which such individuals may, in  the
plan  administrator's  discretion, be  issued shares  of Common  Stock directly,
through the purchase of such  shares at a price per  share not less than 85%  of
fair market value per share at the time of issuance or as a fully-paid bonus for
services  rendered the  Company; and  (iii) the  Automatic Option  Grant Program
under which option grants  will automatically be made  at periodic intervals  to
eligible  non-employee Board  members to purchase  shares of Common  Stock at an
exercise price equal to 100%  of the fair market value  of the option shares  on
the grant date.
 
    The  Discretionary Option Grant  Program and the  Stock Issuance Program are
administered by  the  Compensation  Committee of  the  Board.  The  Compensation
Committee, as plan administrator, has complete discretion, subject to applicable
law,  to determine  which eligible individuals  are to receive  option grants or
stock issuances, the time  or times when such  option grants or stock  issuances
are to be made, the number of shares subject to each such grant or issuance, the
status  of any granted  option as either  an incentive stock  or a non-statutory
stock option under the Federal  tax laws, the vesting  schedule to be in  effect
for  the  option grant  or stock  issuance and  the maximum  term for  which any
granted option  is to  remain outstanding.  In no  event, however,  may any  one
participant  in the 1992 Plan  acquire more than 240,000  shares of Common Stock
under the 1992 Plan, exclusive of any option grants or share issuances  received
prior to January 1, 1994.
 
    The  exercise price for options  granted under the 1992  Plan may be paid in
cash or in outstanding shares of Common Stock. Options may also be exercised  on
a  cashless  basis  through  the  same-day sale  of  the  purchased  shares. The
Compensation Committee may also  permit the optionee to  pay the exercise  price
through  a promissory note or  installment payments over a  period of years. The
amount financed may  include any Federal  or state income  and employment  taxes
incurred by reason of the option exercise.
 
    Each  option granted to an officer of the Company subject to the short-swing
profit restrictions  of  the  Federal  securities laws  may  include  a  special
cash-out  right which provides that, upon the  acquisition of 50% or more of the
Company's outstanding  voting stock  pursuant to  a hostile  tender offer,  such
option,  if outstanding for at least six months, will automatically be cancelled
in exchange for a cash distribution to  the officer based upon the tender  offer
price.
 
                                       46
<PAGE>
    The  Compensation Committee has the authority  to effect, from time to time,
the cancellation of outstanding  options under the 1992  Plan in return for  the
grant  of new options for the same or  different number of option shares with an
exercise price per share based upon the fair market value of the Common Stock on
the new grant date.
 
    In the event the Company is acquired by merger, consolidation or asset sale,
the shares of Common Stock subject to each option outstanding at the time  under
the  1992 Plan will immediately vest in full, except to the extent the Company's
repurchase rights  with  respect to  those  shares are  to  be assigned  to  the
acquiring  entity, and options will accelerate to  the extent not assumed by the
acquiring entity. The Compensation Committee also has discretion to provide  for
the  acceleration  of  one  or  more outstanding  options  under  the  1992 Plan
(including options incorporated from the  Predecessor Plans) and the vesting  of
shares  subject to  outstanding options upon  the occurrence  of certain hostile
tender offers. Such accelerated vesting  may be conditioned upon the  subsequent
termination of the affected optionee's service.
 
    Under the automatic grant program, each individual serving as a non-employee
director on January 23, 1995, and each individual who first joins the Board as a
non-employee  director  on or  after that  date,  will receive  at that  time an
automatic option grant for 15,000 shares of Common Stock. Each option will  have
an  exercise price  equal to the  fair market value  of the Common  Stock on the
automatic grant  date  and a  maximum  term of  ten  years, subject  to  earlier
termination following the optionee's cessation of Board service. The option will
be  immediately exercisable for all of the shares but the shares will be subject
to repurchase  at  original cost.  The  repurchase  right shall  lapse  and  the
optionee  vest in a series  of annual and monthly  installments over a five-year
period, beginning one year from the  grant date. However, vesting of the  shares
will  automatically accelerate upon (i) an acquisition of the Company by merger,
consolidation, or asset sale, or (ii) a hostile takeover of the Company effected
by tender offer  for more  than 50%  of the  outstanding voting  stock or  proxy
contest for Board membership.
 
    In  the event that more  than 50% of the  Company's outstanding voting stock
were to be acquired  pursuant to a hostile  tender offer, each automatic  option
grant  which has been outstanding for at  least six months may be surrendered to
the Company in return for  a cash distribution from  the Company based upon  the
tender  offer  price  per share  of  Common Stock  at  the time  subject  to the
surrendered option.
 
    The Board may amend or modify the 1992 Plan at any time. The 1992 Plan  will
terminate on January 10, 2002 unless sooner terminated by the Board.
 
EMPLOYEE STOCK PURCHASE PLAN
 
    On  August 1, 1994, the Company adopted an Employee Stock Purchase Plan (the
"Purchase Plan"). A total of 200,000  shares of Common Stock have been  reserved
for  issuance under the Purchase  Plan. The Purchase Plan,  which is intended to
qualify under Section  423 of the  Internal Revenue Code,  has been  implemented
through  a series of  offering periods, each  with a maximum  duration of twelve
months, commencing  on August  1, 1994,  with purchases  generally occurring  at
six-month  intervals.  The Purchase  Plan  is administered  by  the Compensation
Committee of  the Board.  Employees  are eligible  to  participate if  they  are
employed  by the Company for at  least 20 hours per week  for more than 5 months
per calendar year  and have been  employed by  the Company for  at least  ninety
days.  The Purchase  Plan permits  eligible employees  to purchase  Common Stock
through  payroll  deductions,  which  may  not  exceed  10%  of  an   employee's
compensation,  nor more than 2,500 shares  per participant on any purchase date.
The price of stock purchased under the Purchase Plan will be 85% of the lower of
the fair market value of the Common Stock at the beginning of the offering or on
the semi-annual  purchase date.  Employees may  end their  participation in  the
offering  at  any  time  during  the  purchase  period,  and  participation ends
automatically on termination  of employment with  the Company. Each  outstanding
purchase  right will be exercised immediately prior to a merger or consolidation
unless assumed by the  acquiring corporation. The Board  may amend or  terminate
the  Purchase Plan immediately after the  close of any purchase period. However,
the Board may not, without stockholder approval, materially increase the  number
of  shares  of Common  Stock  available for  issuance  or materially  modify the
eligibility  requirements  for  participation  or  the  benefits  available   to
participants.

401(K) PROFIT SHARING PLAN
 
    Effective  January 1, 1988, the Company  adopted a retirement profit sharing
plan (the "401(k) Plan") that covers all employees of the Company in the U.S. An
employee may elect to defer, in the form of contributions to the 401(k) Plan, up
to 15% of the total compensation that  would otherwise be paid to the  employee,
currently  not to exceed  $9,500 per calendar  year (adjusted for cost-of-living
increases). Employee contributions are invested in selected equity mutual  funds
or  a money market fund at the  direction of the employee. The contributions are
fully vested and nonforfeitable at all times.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
    The Company's Restated Certificate of Incorporation limits the liability  of
its directors for monetary damages arising from a breach of their fiduciary duty
as  directors, except to  the extent otherwise required  by the Delaware General
Corporation Law. Such limitation of  liability does not affect the  availability
of  equitable remedies  such as injunctive  relief or  rescission. The Company's
Bylaws provide that the  Company shall indemnify its  directors and officers  to
the  fullest extent  permitted by  Delaware law,  including in  circumstances in
which indemnification is otherwise discretionary under Delaware law. The Company
has also entered  into indemnification agreements  with its officers,  directors
and  certain employees containing provisions that may require the Company, among
other things,  to  indemnify  such officers,  directors  and  employees  against
certain  liabilities that  may arise  by reason  of their  status or  service as
directors, officers or  employees (other than  liabilities arising from  willful
misconduct of a culpable nature), to advance their expenses incurred as a result
of  any proceeding against  them as to  which they could  be indemnified, and to
obtain directors' and officers' insurance if available on reasonable terms.  The
Company  believes that these provisions and  agreements are necessary to attract
and retain qualified directors, executive officers and certain employees.
 
    At present,  there is  no  pending litigation  or proceeding  involving  any
director,  officer, employee or agent of  the Company where indemnification will
be required or permitted. The Company is not aware of any threatened  litigation
or proceeding that might result in a claim for such indemnification.
 
                              CERTAIN TRANSACTIONS
 
RELATIONSHIP WITH H-P
 
    In  June 1993, the Company and  H-P modified a previous Coordinated Research
Program Agreement (the "Prior H-P Agreement")  by entering into a new  five-year
agreement  (the "Current H-P Agreement"), which  agreement is subject to earlier
termination by H-P  if H-P's ownership  of the Company's  stock falls below  7%.
Under  the Prior H-P Agreement, H-P and Conductus were involved in several joint
development projects, including  the development  of a  stable, low  phase-noise
oscillator  for microwave test and instrumentation applications using resonators
developed by Conductus, and the development of a variety of digital LTS circuits
for high-speed digital electronic applications. All rights to technology arising
out of joint development projects are owned  jointly by H-P and Conductus. As  a
result,  both  Conductus  and H-P  will  be entitled  to  commercialize products
incorporating such technology.
 
    Any royalties received by either  H-P or Conductus for technology  developed
under  the Prior H-P Agreement will be  divided equally between the two parties,
except that Conductus generally may not  license third parties to make  circuits
based  on  circuit designs  made  solely by  H-P employees  as  part of  a joint
development project or  sell such  circuits to third  parties for  incorporation
into  products for resale. H-P is  a party to certain cross-license arrangements
and may  in the  future enter  into similar  cross-licenses. Consequently,  such
third  parties  may  have  non-exclusive rights  in  technology  developed under
research projects  under  the Prior  H-P  Agreement.  H-P also  has  the  right,
beginning  two years after  information developed under  the Prior H-P Agreement
and three years  after other confidential  information is disclosed  to H-P,  to
disclose  such  information  to  third  parties  or  to  the  public  (including
information disclosed to H-P by Conductus). Conductus has comparable license and
information disclosure rights.
 
                                       48
<PAGE>
    The Current H-P Agreement requires Conductus and H-P to exchange reviews and
assessments of Conductus' technical and applications developments,  particularly
with  respect to their potential application to H-P's product lines. H-P has the
right to appoint an H-P employee (the "H-P Member") as a member of the Company's
Scientific Advisory Board. H-P will jointly own with Conductus any invention  by
the  H-P Member  acting pursuant  to the  H-P Agreement  or using  the Company's
confidential information.
 
    Mr. Anderson,  Vice  President and  General  Manager of  the  Microwave  and
Communication  Group at  H-P, was  nominated for election  as a  director of the
Company by  H-P pursuant  to the  Series B  Preferred Stock  Purchase  Agreement
between  the  Company  and  H-P.  See  "Management  --  Directors  and Executive
Officers."
 
    Between January 1990  and June  1993, Conductus  and H-P  entered into  four
equipment lease lines, pursuant to which Conductus leased equipment and incurred
monthly payments in the aggregate of approximately $166,500, including principal
and interest. Three of the four lease lines expired in May 1993.
 
SELECTED PREVIOUS FINANCINGS
 
    In  October  1992  and January  1993,  the  Company raised  an  aggregate of
$2,000,000  to  finance  its  operations  through  the  issuance  of  $1,980,000
principal  amount of  convertible promissory  notes bearing  interest at  9% per
annum (the  "Promissory Notes"),  and warrants  to purchase  Series B  Preferred
Stock  that converted into warrants to purchase an aggregate of 33,460 shares of
Common Stock at the closing of the Company's initial public offering (the "IPO")
in August 1993. The warrants had an effective exercise price of $8.96 per  share
of  Common Stock. The Promissory Notes and warrants were issued to affiliates of
the following persons,  each of  which beneficially owned  more than  5% of  the
Company's Common Stock as of March 31, 1996:

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
    The  Company's Restated Certificate of Incorporation limits the liability of
its directors for monetary damages arising from a breach of their fiduciary duty
as directors, except to  the extent otherwise required  by the Delaware  General
Corporation  Law. Such limitation of liability  does not affect the availability
of equitable remedies  such as  injunctive relief or  rescission. The  Company's
Bylaws  provide that the  Company shall indemnify its  directors and officers to
the fullest  extent permitted  by Delaware  law, including  in circumstances  in
which indemnification is otherwise discretionary under Delaware law. The Company
has  also entered into  indemnification agreements with  its officers, directors
and certain employees containing provisions that may require the Company,  among
other   things,  to  indemnify  such  officers  and  directors  against  certain
liabilities that may arise by reason of their status or service as directors  or
officers,  to  advance their  expenses incurred  as a  result of  any proceeding
against them as to which they could be indemnified, and to obtain directors' and
officers' insurance  if  available  on  reasonable  terms.  See  "Management  --
Limitation of Liability and Indemnification Matters."
 
OPTION GRANTS
 
    On  January 23,  1995, the  Company granted  each of  Dr. Shoch  and Messrs.
Cooper, McKenna and Sun an option to  purchase 15,000 shares of Common Stock  at
an  exercise price  of $4.93  per share pursuant  to the  Automatic Option Grant
Program under  the 1992  Plan. On  January  25, 1996,  the Company  granted  Mr.
Saldich an option to purchase 15,000 shares of Common Stock at an exercise price
of  $6.50 per share pursuant to the  same program. See "Management -- 1992 Stock
Option/Stock Issuance Plan."
 
    On May  3, 1994,  the Company  granted Mr.  Shalvoy options  to purchase  an
aggregate  of 250,000 shares of  Common Stock at an  exercise price of $5.50 per
share, including 240,000 shares granted pursuant to the 1992 Plan, in connection
with Mr. Shalvoy joining the Company  as President and Chief Executive  Officer.

or more series and to fix  the rights, preferences, privileges and  restrictions
thereof,  including dividend  rights, dividend rates,  conversion rights, voting
rights, terms of redemption, redemption prices, liquidation preferences and  the
number  of shares  constituting any  series or  the designation  of such series,
without further  vote or  action  by the  stockholders.  See "  --  Antitakeover
Effects  of Provisions of  the Restated Certificate  of Incorporation and Bylaws
and of Delaware Law -- Restated  Certificate of Incorporation." At present,  the
Company has no plans to issue any of the Preferred Stock.
 
ANTITAKEOVER EFFECTS OF PROVISIONS OF THE RESTATED CERTIFICATE OF INCORPORATION
AND BYLAWS AND OF DELAWARE LAW
 
  RESTATED CERTIFICATE OF INCORPORATION
 
    Under  the  Company's Restated  Certificate of  Incorporation, the  Board of
Directors has the power to authorize the  issuance of up to 1,000,000 shares  of
Preferred  Stock and to determine the price, rights, preferences, privileges and
restrictions, including voting rights, of  those shares without further vote  or
action  by the  stockholders. The issuance  of Preferred  Stock, while providing
desirable  flexibility  in  connection  with  possible  acquisitions  and  other
corporate  purposes, may have the effect  of delaying, deferring or preventing a
change in control of the Company, may discourage bids for the Common Stock at  a
premium over the market price of the Common Stock and may have an adverse effect
on  the market price  of and the voting  and other rights of  the holders of the
Common Stock. In  addition, the Restated  Certificate of Incorporation  provides
that  all stockholder actions must be effected  at a duly called meeting and not
by a  consent  in writing.  These  provisions  of the  Restated  Certificate  of
Incorporation  could discourage potential acquisition  proposals and could delay
or prevent a change in control of the Company. These provisions are intended  to
enhance  the likelihood  of continuity and  stability in the  composition of the
Board of Directors and in the policies formulated by the Board of Directors  and
to  discourage  certain types  of  transactions that  may  involve an  actual or
threatened change of control  of the Company. These  provisions are designed  to
reduce  the vulnerability of the Company to an unsolicited acquisition proposal.
These provisions are also intended
 
                                       53
<PAGE>
to discourage certain tactics  that may be used  in proxy fights. However,  such
provisions  could  have the  effect of  discouraging  others from  making tender
offers for the  Company's shares and,  as a consequence,  they also may  inhibit
fluctuations in the market price of the Company's shares which could result from
actual or rumored takeover attempts. Such provisions also may have the effect of
preventing changes in the management of the Company. See "Risk Factors -- Effect
of  Certain Charter Provisions; Antitakeover  Effects of Restated Certificate of
Incorporation and Bylaw Provisions and of Delaware Law."
 
  DELAWARE TAKEOVER STATUTE
 
    The Company is subject  to Section 203 of  the Delaware General  Corporation
Law  ("Section 203"), which, subject to certain exceptions, prohibits a Delaware
corporation from  engaging  in  any business  combination  with  any  interested
stockholder for a period of three years following the date that such stockholder
became  an interested stockholder, unless: (i) prior  to such date, the board of
directors of the  corporation approved  either the business  combination or  the
transaction that resulted in the stockholder becoming an interested stockholder;
(ii)  upon  consummation of  the transaction  that  resulted in  the stockholder
becoming an interested  stockholder, the interested  stockholder owned at  least
85%  of  the  voting  stock  of the  corporation  outstanding  at  the  time the
transaction commenced,  excluding  for purposes  of  determining the  number  of
shares  outstanding those shares owned (x) by persons who are directors and also
officers and (y) by employee stock  plans in which employee participants do  not
have  the right to  determine confidentially whether shares  held subject to the
plan will be tendered in a tender  or exchange offer; or (iii) on or  subsequent
to such date, the business combination is approved by the board of directors and
authorized  at an annual or special meeting  of stockholders, and not by written
consent, by the affirmative vote of at  least 66 2/3% of the outstanding  voting
stock that is not owned by the interested stockholder.
 
    Section  203  defines business  combination to  include:  (i) any  merger or
consolidation involving the corporation and the interested stockholder; (ii) any
sale, transfer, pledge or other disposition of 10% or more of the assets of  the
corporation  involving  the  interested stockholder;  (iii)  subject  to certain
exceptions, any transaction  that results  in the  issuance or  transfer by  the
corporation  of any stock of the corporation to the interested stockholder; (iv)
any transaction involving the corporation that has the effect of increasing  the
proportionate  share of  the stock  of any  class or  series of  the corporation
beneficially owned by  the interested  stockholder; or  (v) the  receipt by  the
interested  stockholder  of  the  benefit of  any  loans,  advances, guarantees,
pledges or other financial benefits provided  by or through the corporation.  In
general,  Section 203 defines an interested  stockholder as any entity or person
beneficially owning  15%  or  more  of  the  outstanding  voting  stock  of  the
corporation  and  any  entity  or  person  affiliated  with  or  controlling  or
controlled by such entity or person.
 
REGISTRATION RIGHTS
 
    Pursuant to the  Second Amended and  Restated Registration Rights  Agreement
among   the  Company   and  certain   stockholders  (the   "Registration  Rights
Agreement"), holders of approximately 1,877,000  shares of Common Stock and  any
shares  of Common Stock issued as a  dividend or other distribution with respect
to, in exchange for, or in  replacement of, such approximately 1,877,000  shares
of  Common Stock and 18,534  shares issuable upon exercise  of a certain warrant
(collectively, the "Registrable Securities") will be entitled to certain  rights
with  respect  to  the  registration of  the  Registrable  Securities  under the
Securities Act. Under  the terms of  the Registration Rights  Agreement, if  the
Company  proposes to register any of its securities under the Securities Act for
its own  account, holders  of the  Registrable Securities,  as well  as  139,813
shares of Common Stock held by seven consultants and 15,000 shares issuable upon
exercise  of a certain warrant  (collectively, the "Consultant Securities"), are
entitled to  notice of  such  registration and  are  entitled to  include  their
Registrable   Securities  and/or   Consultant  Securities   therein  ("piggyback
registration"). Holders of the Registrable Securities and Consultant  Securities
waived  their  rights  under  the  Registration  Rights  Agreement  to piggyback
registration in connection with this  offering. Beginning four months after  the
effective  date of this offering and  subject to certain dollar limitations, the
holders of Registrable Securities may also require the Company, on no more  than
two  occasions, to file  a registration statement under  the Securities Act with
respect to their Registrable Securities and  the Company is required to use  its
best efforts
 
                                       54
<PAGE>
to  effect  such  registration  ("requested  registration").  In  addition, upon
qualification of the Company to file  registration statements on Form S-3  under
the  Securities  Act  and  subject to  certain  dollar  limitations,  holders of
Registrable  Securities  are   entitled  to  request   the  Company  to   effect
registrations  of the Registrable  Securities on Form  S-3 ("S-3 registration").
The foregoing  rights to  registration are  subject to  certain limitations  and
conditions, including the underwriters' right to limit the number of Registrable
Securities  and  Consultant Securities  being  registered pursuant  to piggyback
registrations and the Company's right to delay requested and S-3 registration in
good faith. The Company is required  to bear the expenses relating to  requested
and  piggyback registrations and the first two S-3 registrations, except for the
selling stockholders'  pro  rata  portion  of  the  underwriting  discounts  and
commissions.
 
    The  following entities which may be considered "affiliates" of the Company,
as that term is defined in the  Securities Act, own a total of 1,398,474  shares

on the Nasdaq National Market during the four (4) calendar weeks preceding  such
sale.  Sales  under  Rule  144  are  also  subject  to  certain  manner  of sale
provisions,  notice  requirements  and   the  availability  of  current   public
information  about the affiliate  of the Company  at any time  during the ninety
(90) days preceding a sale, and who  has beneficially owned shares for at  least

holders), would be entitled to sell such shares under Rule 144(k) without regard
to the  volume  limitations,  manner  of  sale  provisions,  public  information
requirements or notice requirements.

    The  Underwriters will purchase  all shares of  Common Stock offered hereby,
other than  over-allotment shares,  if any  of such  shares are  purchased.  The
Underwriting Agreement provides that the obligations of the several Underwriters
are subject to conditions precedent specified therein. In the event of a default
by  an  Underwriter,  the  commitment  set  forth  above  of  the non-defaulting
Underwriter may be increased or the Underwriting Agreement may be terminated.
 
   
    The Company has been  advised by the  Representatives that the  Underwriters
propose  to offer the shares of Common Stock to the public at the offering price
set forth on the cover  page of this Prospectus and  to certain dealers at  such
price  less a  concession not  in excess  of $0.32  per share.  Such dealers may
reallow, a concession not in excess of $0.10 per share to certain other dealers.
After the public offering, the public offering price, concession and reallowance
to dealers may be changed by the Underwriters.
    
 
    The Company has granted  to the Underwriters an  option, exercisable by  the
Underwriters not later than 30 days after the effective date of this Prospectus,
to  purchase  up to  150,000 additional  shares  of Common  Stock at  the public
offering price, less the  underwriting discount set forth  on the cover page  of
this Prospectus. The Underwriters may exercise such option, in whole or in part,
only  to cover over-allotments made in connection  with the sale of Common Stock
offered hereby. To the extent that  the Underwriters exercise such option,  each
Underwriter  will become obligated,  subject to certain  conditions, to purchase
approximately the same percentage  thereof that the number  of shares of  Common
Stock  to be purchased by it shown in  the above table bears to the total shown,
and the Company will be obligated, pursuant  to the option, to sell such  shares
to the Underwriters.
 
    In  connection with  this offering,  certain underwriters  and selling group
members may engage in passive market making transactions in the Common Stock  on
the  Nasdaq National  Market immediately prior  to the commencement  of sales in
this offering, in accordance with Rule 10b-6A under the Securities Exchange  Act
of  1934,  as  amended  ("Exchange  Act").  Passive  market  making  consists of
displaying bids  on the  Nasdaq National  Market limited  by the  bid prices  of
independent  market makers and purchases limited  by such prices and effected in
response to order flow. Net purchases by a passive market maker on each day  are
limited  to a specified  percentage of the passive  market maker's average daily
trading volume  in  the Common  Stock  during a  specified  period and  must  be
discontinued when such limit is reached. Passive market making may stabilize the
market  price of the  Common Stock at  a level above  that which might otherwise
prevail and, if commenced, may be discontinued at any time.
 
    The Company  has  agreed  to  indemnify  the  Underwriters  against  certain
liabilities, including liabilities under the Securities Act and to contribute to
certain payments that the Underwriters may be required to make.
 
    The  Company has agreed that during the 90-day period commencing on the date
hereof, the  Company will  not,  without the  prior  written consent  of  Tucker
Anthony Incorporated, as Representative of the Underwriters, issue, offer, agree
to  sell, sell, grant any option for  the sale of, transfer or otherwise dispose
of any  shares of  Common Stock  other than  pursuant to  currently  outstanding
options,  warrants or convertible securities  (other than employee stock options
and  Common  Stock   currently  authorized  under   the  Company's  1992   Stock
Option/Stock  Issuance  Plan and  Employee Stock  Purchase Plan).  The Company's
officers, directors and certain stockholders have agreed that during the  90-day
period commencing on the date hereof
 
                                       56
<PAGE>
they will not, without the prior written consent of Tucker Anthony Incorporated,
as  Representative of the  Underwriters, offer, pledge,  contract to sell, sell,
grant any option for the sale of, transfer or otherwise dispose of any shares of
Common Stock other  than gifts or  transfers by will  or intestacy to  immediate
family  members,  shareholders  of  a corporate  stockholder  or  partners  of a
stockholder that is a  partnership, provided that the  transferee agrees to  the
same limitations.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
Conductus, Inc.:
 
    We  have audited  the accompanying balance  sheets of Conductus,  Inc. as of
December  31,  1995  and  1994,  and  the  related  statements  of   operations,
stockholders'  equity and cash flows  for each of the  three years in the period
ended December 31, 1995.  These financial statements  are the responsibility  of
the  Company's management. Our responsibility is  to express an opinion on these
financial statements based on our audits.
 
    We conducted  our  audits in  accordance  with generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence  supporting
the  amounts and disclosures in the financial statements. An audit also includes
assessing the  accounting  principles used  and  significant estimates  made  by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial  statements referred to above present  fairly,
in  all  material respects,  the  financial position  of  Conductus, Inc.  as of
December 31, 1995 and 1994, and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 1995, in conformity
with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
           (INFORMATION AS OF MARCH 31, 1996 AND FOR THE THREE MONTHS
      ENDED MARCH 31, 1996 AND 1995 AND AFTER MARCH 31, 1996 IS UNAUDITED)
 
1.  FORMATION AND BUSINESS OF THE COMPANY:
    The  Company was formed  to develop, manufacture  and market superconductive
electronic devices, circuits  and systems for  sensor, communications, test  and
instrumentation,  and digital electronics applications. Effective June 28, 1994,
the Company  dissolved its  subsidiary, Tristan  Technologies, Inc.  ("Tristan")
acquired in May 1993 and the former Tristan operations have become the Company's
Instrument  and Systems Division. At that  date, the Company discontinued use of
"Consolidated" in the financial statements.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
    FISCAL YEAR:
 
    The Company uses a 52-53 week fiscal  year ending on the last Friday of  the
month.  For convenience  of presentation, the  accompanying financial statements
have been shown as ending on December 31 of each applicable period.
 
    USE OF ESTIMATES:
 
    The  preparation  of  financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions that  affect the  reported  amounts of  assets and  liabilities  and
disclosure  of contingent  assets and liabilities  at the date  of the financial
statements and  the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.
 
    CERTAIN RISKS AND CONCENTRATIONS:
 
    The  Company's superconducting  products are concentrated  in the electronic
component industry which  is highly competitive  and rapidly changing.  Revenues
for  the Company's products are concentrated with a relatively limited number of
customers and  supplies for  certain  components are  concentrated among  a  few
providers.   The  development  of  new   technologies  or  commercialization  of
superconductive products  by  any  competitor  could  affect  operating  results
adversely.
 
    CASH, CASH EQUIVALENTS AND INVESTMENTS:
 
    The  Company  considers  all  highly liquid  investments  purchased  with an
original maturity of three months or  less to be cash equivalents.  Investments,
which  consist  primarily of  U.S. government  obligations, corporate  bonds and
commercial paper, are stated at fair market value. Management believes that  the
financial institutions in which it maintains such deposits are financially sound
and,  accordingly, minimal  credit risk exists  with respect  to these deposits.
Additionally, cash and cash equivalents are held by two major banks.
 
    Other financial  instruments,  principally accounts  receivable  and  leases
payable,  are considered to approximate fair  value based upon comparable market
information available at respective balance sheet dates.
 
    As of April 1, 1994, the  Company adopted Statement of Financial  Accounting
Standards  No. 115 ("SFAS 115"), "Accounting for Certain Investments in Debt and
Equity Securities" which  requires a change  in the method  used to account  for
certain  investments. All investments at April 1, 1994 were deemed by management
to be available-for-sale and  therefore are reported at  fair market value  with
net  unrealized losses reported as a separate component of stockholders' equity.
Available-for-sale marketable securities with maturities less than one year from
the balance sheet date  are classified as short-term  and those with  maturities
greater  than one year from the balance  sheet date are classified as long term.
Adoption of SFAS 115 did not have  a material effect on the Company's  financial
statements.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
           (INFORMATION AS OF MARCH 31, 1996 AND FOR THE THREE MONTHS
      ENDED MARCH 31, 1996 AND 1995 AND AFTER MARCH 31, 1996 IS UNAUDITED)
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    INVENTORIES:
 
    Inventories  are  stated at  the lower  of cost  (determined on  a first-in,
first-out basis) or market. Appropriate consideration is given to  obsolescence,
excessive  levels, deterioration and other  factors in evaluating net realizable
value.
 
    PROPERTY AND EQUIPMENT:
 
    Property and equipment are recorded at cost, net of accumulated depreciation
and amortization.
 
    Depreciation of property and equipment are computed using the  straight-line
method  over  estimated  useful lives  of  four  to six  years.  Amortization of
leasehold improvements  is  computed using  the  straight-line method  over  the
shorter of the useful life of the assets and the related lease term.
 
    REVENUE RECOGNITION:
 
    Product revenues are recognized at the time of shipment.
 
    RESEARCH AND DEVELOPMENT CONTRACTS:
 
    The  Company has entered into contracts  to perform research and development
for the U.S. government. Revenues from these contracts are recognized  utilizing
the  percentage-of-completion  method  measured  by  the  relationship  of costs
incurred  to  total  contract  costs.  Costs  include  direct  engineering   and
development costs and applicable overhead.
 
    RESEARCH AND DEVELOPMENT:
 
    Internally  funded  research  and development  expenditures  are  charged to
operations as incurred.
 
    INCOME TAXES:
 
    The Company utilizes the liability method of accounting for income taxes, as
set forth  in Statement  of  Financial Accounting  Standards ("SFAS  No.  109"),
"Accounting  for Income Taxes."  Under the liability  method, deferred taxes are
determined based on the difference between the financial statement and tax bases
of assets and  liabilities using enacted  tax rates  in effect in  the years  in
which the differences are expected to reverse.
 
    UNAUDITED INTERIM FINANCIAL STATEMENTS:
 
    The accompanying unaudited interim financial statements for the three months
ended  March 31, 1996 and  1995 have been prepared  in accordance with generally
accepted  accounting  principles  for  interim  financial  information  and  the
instructions  to Article 10 of Regulation  S-X. Accordingly, they do not include
all of  the information  and  notes required  by generally  accepted  accounting
principles for complete financial statements. In the opinion of the Company, all
adjustments  (consisting of only normal recurring accruals) considered necessary
to present fairly the financial position as of March 31, 1996 and the statements
of operations, stockholders' equity and cash  flows for the three month  periods
ended March 31, 1996 and 1995 have been included.
 
    RECLASSIFICATIONS:
 
    Certain  amounts in the December 31, 1994 and 1993 financial statements have
been reclassified  to conform  to the  presentation at  December 31,  1995.  The
reclassifications  had no impact on previously reported net losses, total assets
or net cashflows.
 
    COMPUTATION OF NET LOSS PER COMMON SHARE:
 
    Net loss  per common  share is  based upon  the weighted  average number  of
common  shares outstanding. Common  equivalent shares have  not been included in
the per share calculations as the effect would not be dilutive.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    RECENT PRONOUNCEMENTS:
 
    During March 1995, the Financial Accounting Standards Board issued Statement
No. 121 ("SFAS 121"),  "Accounting for the Impairment  of Long-Lived Assets  and
for Long-Lived Assets to Be Disposed Of." SFAS 121 will become effective for the
Company's   year  ending  December  31,  1996.   The  Company  has  studied  the
implications of SFAS 121 and, based  on its initial evaluation, does not  expect
it  to have a material impact on the Company's financial condition or results of
operations.
 
    During  October  1995,  the  Financial  Accounting  Standards  Board  issued
Statement  No. 123 ("SFAS 123"), "Accounting for Stock-Based Compensation" which
established a fair value based method of accounting for stock-based compensation
plans and requires additional disclosures for  those companies who elect not  to
adopt  the new method  of accounting. The  Company will continue  to account for
employee purchase rights and stock options under APB Opinion No. 25, "Accounting
for Stock Issued to Employees." SFAS  No. 123 disclosures will be effective  for
fiscal years beginning after December 15, 1995.

10. LONG-TERM DEBT AND OTHER BORROWINGS:
    In March 1996, the Company added to its $2,000,000 equipment credit facility
with a financial institution to finance costs associated with the acquisition of
equipment by adding a second facility for $1,000,000. All borrowings under these
credit facilities are at the bank's prime rate plus 1.00% (9.50% at December 31,
1995)  with  interest  paid  monthly,  and  are  collateralized  by  the related
equipment.  Principal  installments  under  the  $2,000,000  facility  commenced
September  1995  and mature  over  a thirty-six  (36)  month period  as follows:
$687,736, $687,736  and  $458,491  in  1996, 1997  and  1998,  respectively.  At
December  31, 1995,  no additional amounts  were available  under the $2,000,000
credit facility. The  $1,000,000 facility matures  over a 34  month period.  The
Company is restricted from paying cash dividends but may pay stock dividends.
 
    The  Company in March 1996 modified its  line of credit facility with a bank
to expire February  28, 1997. The  agreement provides for  borrowings up to  the
lesser  of  $2,000,000  or 75%  of  eligible receivables.  Borrowings  under the
agreement bear interest at the bank's prime rate plus 0.50% (9% at December  31,
1995)  and are collateralized by accounts receivable, equipment and other assets
of the Company. At December  31, 1995, the Company  has no borrowings under  the
agreement  and had $1,000,000 available under  the line of credit. In connection
with this modification, on March 8, 1996, the Company issued the lender warrants
to acquire 15,000 shares of the Company's common stock at a price of $11.25  per
share.  These warrants  may be  exercised by  the holder  at any  time until the
expiration date, March 8, 2001.
 
    The two equipment credit facilities and line of credit facility require that
the Company provide financial information to the lender, obtain approval of  the
lender  for any  material disposition of  the collateral except  in the ordinary
course of  business and  meet  certain financial  ratios, minimum  tangible  net
worth, minimum cash and investments and other covenants.
 
    Warrants  to acquire 33,460 shares of common  stock, at a price of $8.96 per
share, issued in connection with the issuance of convertible promissory notes in
1993 and 1992, expired in August 1995.
 
11. COMMITMENTS:
    The Company  leases  its administrative,  sales,  marketing,  manufacturing,
research   and  development  facilities  under  noncancelable  operating  leases
expiring in February  1998 and  August 2000  and 2001.  Under the  terms of  the
leases, the Company is responsible for certain expenses and taxes.

reassignment right upon termination of the Agreement.
 
    COORDINATED RESEARCH PROGRAM:
 
    In May  1993, the  Company and  Hewlett-Packard Company  ("H-P") modified  a
previous  Coordinated Research Program ("CRP") agreement  by entering into a new
five-year agreement.

assessments   of   the  Company's   technical  and   applications  developments,
particularly with respect to their potential application to H-P's products.  H-P
has the right to appoint an H-P employee as a member of the Company's Scientific
Advisory  Board,  and the  Company agreed  to use  its best  efforts to  cause a
nominee to be elected to the Board of Directors. Under this agreement, H-P  will
not  have rights to any of the Company's inventions, except that it will jointly
own with the Company any invention developed  by the H-P Member pursuant to  the
agreement  or using the Company's confidential information. As a result, H-P and
the Company will each be entitled to

    CONSORTIUM FOR SUPERCONDUCTING ELECTRONICS:
 
    The Company is a  member of the  Consortium for Superconducting  Electronics
formed  to conduct research and development  programs leading to applications of
superconductive electronics. The Company  is presently participating with  other
members  of  the  Consortium in  two  projects  relating to  the  development of
superconductive wireless communications.
 
    The Company has been  granted a non-exclusive, royalty  free license to  all
intellectual  property  conceived  or  first  actually  reduced  to  practice in
connection with  any  work under  a  Consortium  project in  which  the  Company
participates  while the  Company is  a member. The  Company must  pay a one-time
license fee  for commercializing  any invention  covered by  a  "commercialized"
patent  licensed to it  by a university member  or government laboratory member.
The fee is  $50,000 or, in  some cases, $25,000.  (A patent is  "commercialized"
when  the Company's  revenues from  external sales  of products  covered by such
patent exceed $2,000,000). The Company may also be required to pay a license fee
for commercializing any  invention covered by  a "highly commercialized"  patent
licensed  to it by a university member, if the patent is owned solely or jointly
by a university or government laboratory member and if the patent is  determined
to  be a "basic" patent  (i.e., a patent is "basic"  if it represents a singular
contribution of profound commercial  significance) under procedures  established
by  the Consortium. The  initial fee may  not exceed $1,000,000.  In addition, a
second fee  may  be  established  after  five  years  in  accordance  with  such
procedures which may not exceed $5,000,000. (A patent is "highly commercialized"
if the Company's revenues from external sales of products covered by such patent
exceed $10,000,000).
 
    ADVANCED TECHNOLOGY PROGRAM:
 
    In  August 1992, the Company, acting as administrator for and on behalf of a
joint  venture  formed  to  conduct  research  to  develop  a  prototype  hybrid
superconductor/semiconductor  computer under the Department of Commerce Advanced
Technology Program, entered into a  cost-sharing cooperative agreement with  the
U.S.  government. The  U.S. government  is expected  to financially  support the
project in one-year increments over a total five-year period. Under the terms of
the first-four years of the agreement, the U.S. government agreed to share costs
of the  joint  venture's research  effort  up  to an  aggregate  of  $5,959,596,
including  subcontractor costs. The estimated cost of the total research efforts
in 1995, 1994 and 1993 were $3,719,572, $3,174,740 and $2,743,148, respectively.
Revenue  of  $1,920,020,  $1,520,390   and  $1,369,928  which  represented   the
government's  cost-sharing portion of 42.60%,  48.30% and 49.94%, was recognized
under this contract for 1995, 1994 and 1993, respectively.

and 9,664 shares  of common  stock, at  a price per  share of  $6.08 and  $8.96,
respectively.  As of  March 31,  1996, warrants for  16,447 and  1,087 shares of
common  stock  remain  exercisable,  respectively.  The  warrants,  which   were
immediately exercisable, expire August 5, 1998.
 
    1992 STOCK OPTION/STOCK ISSUANCE PLAN:
 
    The  Company's 1992 Stock Option/Stock Issuance  Plan (the "Plan") serves as
the successor equity  incentive program  to the  Company's 1987  and 1989  Stock
Option  Plans (the "Predecessor Plans"). All outstanding stock options under the
Predecessor Plans will continue  to be governed by  the terms and conditions  of
the Predecessor Plans and the specific instruments evidencing those options, but
no additional options will be granted under the Predecessor Plans.
 
    A  total of  1,580,000 shares  of common  stock are  authorized for issuance
under the  Plan  as of  December  31, 1995.  Such  authorized share  reserve  is
comprised  of 7,812  shares originally  approved under  the Plan,  the aggregate
outstanding shares under the Plan (approximately 689,912 shares) and an increase
of 882,276 shares  under amendments  to the  Plan. The  individuals eligible  to
receive  option grants or  stock issuances pursuant  to the Plan  are limited to
employees (including officers and directors)  and consultants of the Company  or
any  parent or subsidiary corporations. Each non-employee Board member who first
becomes a non-employee Board  member at any  time on or  after January 23,  1995
shall  automatically  be  granted  at  the  time  of  such  initial  election or
appointment an option to purchase 15,000 shares of common stock.
 
    The Plan is divided into two  separate components: the option grant  program
and  the  stock  issuance  program. Under  the  option  grant  program, eligible
individuals may be granted incentive stock options or nonstatutory options.  The
exercise  price of  incentive stock  options granted under  the Plan  must be at
least equal to the fair market value of the common stock of the Company on  date
of grant. The exercise price of nonstatutory options granted under the Plan must
be  not less than 85%  of the fair market  value of the common  stock on date of
grant.  The  stock  issuance  program  allows  eligible  individuals  to  effect
immediate  purchases of the Company's  common stock at fair  market value or for
such consideration as the Compensation Committee deems advisable.
 
    Options granted under the  Plan may be immediately  exercisable for all  the
option  shares, on either a vested or  unvested basis, or may become exercisable
for fully  vested shares  in one  or more  installments over  the  participant's
period  of service. Shares issued under the stock issuance program may either be
vested upon issuance or subject to a vesting schedule tied to the  participant's
period of future service or to the attainment of designated performance goals.
 
    No option may be granted with a term exceeding ten years. However, each such
option  may  be  subject  to  earlier  termination  within  a  designated period
following the optionee's cessation of service with the Company.
 
    In 1992, the Company recognized a compensation charge of $295,000, which  is
being  amortized to the statement  of operations over the  vesting period of the
related options as a  result of a  "deemed" fair market value  in excess of  the
exercise  price of the options in connection with the initial public offering of
the Company's stock. As of December 31, 1995, $91,127 remains to be amortized.
