THIS SUMMARY DOES NOT CONTAIN ALL OF THE INFORMATION THAT YOU SHOULD CONSIDER
BEFORE INVESTING IN OUR COMMON STOCK. REFERENCES IN THIS PROSPECTUS TO

                          SOUTHWALL TECHNOLOGIES INC.

    We are a leading developer, manufacturer and marketer of thin-film coatings
for the electronic display, automotive glass, and residential and commercial
building glass markets. Using our core thin-film sputtering technology, we have
developed a variety of products that selectively absorb, reflect or transmit
light, and electromagnetic and infrared emissions. Our products consist of
anti-reflective films for computer and television screens, including flat panel
and plasma displays, transparent conductive films for use in touch screen and
liquid crystal displays, and transparent insulation and solar-control films for
automotive and building glass.

    Recent advances in manufacturing processes coupled with improved thin-film
deposition techniques in the electronic display and automotive markets are
decreasing production costs, which allows thin-film coated substrates to more
cost-effectively address the following markets:

    ELECTRONIC DISPLAYS.  The thin-film coated substrates we sell in this market
primarily reduce glare caused by reflection from glass surfaces, improve
contrast and image quality, and reduce electromagnetic emission and build up of
static charge on computer display screens. Thin-film coated substrates are used
in computer display tubes, or CDTs, liquid crystal and plasma displays, and in
applications such as touch screens, wireless telephones and automated teller
machines. The market for 17 inch and larger flat screen CDTs is anticipated to
grow from 4 million units in 1999 to 32 million units in 2003, according to
Stanford Resources, Inc.

    AUTOMOTIVE GLASS.  The thin-film coated substrates we sell in this market
reflect infrared heat and reduce ultra-violet light. These coatings allow
carmakers to use more glass and to increase the energy efficiency and comfort of
their vehicles. We sell thin-film coated substrates in this market primarily to
original equipment manufacturers for sale to European manufacturers of new cars.
These products are used in cars manufactured by Mercedes Benz, Renault, Audi,
BMW, Volvo, Volkswagon and the PSA Group, among other companies.

    RESIDENTIAL AND COMMERCIAL BUILDINGS.  The thin-film coated substrates we
sell in this market are primarily used to control the transmission of heat
through window glass and to limit ultra-violet light damage. The primary source
of heat build-up and loss in buildings is through glass windows. According to
The Freedonia Group, the market for new and replacement glass sold for use in
residential buildings is expected to increase from approximately 2.1 billion
square feet in 1998 to approximately 2.7 billion square feet in 2008. Also
according to Freedonia, the market for new and replacement glass for use in
commercial buildings is expected to increase from approximately 680 million
square feet in 1998 to approximately 1.3 billion square feet in 2008.

    Our strategy is to enhance our position as a leading developer, manufacturer
and marketer of thin-film coatings on flexible substrates for our target
markets.

    To address market demands, we are currently expanding our operations
aggressively. We recently opened a new facility in Dresden, Germany and are
commissioning two new production machines in Dresden. We are also in the process
of increasing the commercial production of our second production machine in
Tempe, Arizona. The following are key elements of our strategy:

                                       1
<PAGE>
       - capitalize on expanding flat screen display market;

       - expand production capacity to meet current demand in the electronic
         display and automotive markets;

       - increase automotive market penetration and expand customer base;

       - develop new applications for the automotive glass market; and

       - integrate new production technology.

    We were formed in 1979 as a Delaware corporation. Our principal executive
offices are located at 1029 Corporation Way, Palo Alto, California 94303, and
our telephone number is (650) 962-9111. Our corporate web site is located at

                      SUMMARY CONSOLIDATED FINANCIAL DATA
                     (IN THOUSANDS, EXCEPT PER SHARE DATA)

    The following tables summarize consolidated statements of operations and
consolidated balance sheet data for our business. You should read this
information together with "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and our consolidated financial statements
and the related notes included elsewhere in this prospectus. The pro forma as
adjusted consolidated balance sheet data reflects the sale of 2,500,000 shares
of common stock offered by us at an assumed public offering price of $10.50,
after deducting estimated underwriting discounts and commissions and estimated
offering expenses.

    The consolidated statements of operations data for the five years ended
December 31, 1999 are derived from our consolidated financial statements audited
by PricewaterhouseCoopers LLP, independent accountants. The consolidated
statements of operations data for the three months ended April 4, 1999 and
April 2, 2000 and the consolidated balance sheet data as of April 2, 2000 have
not been audited. In the opinion of our management, such unaudited financial
statements have been prepared on the same basis as the audited financial
statements referred to above and include all adjustments, consisting only of
normal recurring adjustments, necessary for a fair presentation of results of
operations for the indicated period. Results of operations for the three months
ended April 2, 2000 are not necessarily indicative of the results that may be
expected for the full year.

                                  RISK FACTORS

    AN INVESTMENT IN OUR COMMON STOCK INVOLVES A HIGH DEGREE OF RISK. YOU SHOULD
CONSIDER CAREFULLY THE FOLLOWING RISKS, TOGETHER WITH ALL OTHER INFORMATION
INCLUDED IN THIS PROSPECTUS, BEFORE YOU DECIDE TO BUY OUR COMMON STOCK. IF ANY
OF THE FOLLOWING RISKS ACTUALLY OCCUR, OUR BUSINESS, PROSPECTS, FINANCIAL
CONDITION OR RESULTS OF OPERATIONS WOULD LIKELY SUFFER MATERIALLY. AS A RESULT,
THE TRADING PRICE OF OUR COMMON STOCK MAY DECLINE, AND YOU COULD LOSE ALL OR
PART OF THE MONEY YOU PAID TO BUY OUR COMMON STOCK.

                   RISKS RELATED TO OUR INDUSTRY AND BUSINESS

OUR QUARTERLY REVENUE AND OPERATING RESULTS ARE VOLATILE AND DIFFICULT TO
PREDICT. IF WE FAIL TO MEET THE EXPECTATIONS OF PUBLIC MARKET ANALYSTS OR
INVESTORS, THE MARKET PRICE OF OUR COMMON STOCK MAY DECREASE SIGNIFICANTLY.

    Our quarterly revenue and operating results have varied significantly in the
past and will likely vary significantly in the future. Our revenue and operating
results may fall below the expectations of securities analysts or investors in
future periods. Our failure to meet these expectations would likely adversely
affect the market price of our common stock.

    Our quarterly revenue and operating results may vary depending on a number
of factors, including:

    - manufacturing and operational difficulties that may arise due to, among
      other things, expansion of our production capacity, the transfer of
      equipment and personnel to our international manufacturing facility, and
      the hiring and training of additional staff;

    - our possible ability to introduce new products and technologies on a
      timely basis, and the increased research, development and engineering
      costs and marketing expenses associated with new product introductions;

    - fluctuating customer demand, which is influenced by a number of factors,
      including general economic conditions in the sputtered thin-film coatings
      industry, market acceptance of our products and the products of our
      customers, changes in the product mix demanded and offered, and the
      timing, cancellation or delay of customer orders and shipments;

    - competition, including the introduction or announcement of new products by
      competitors, the adoption of competitive technologies by our customers,
      the addition of new production capacity by competitors and competitive
      pressures on prices of our products and those of our customers; and

    - the timing of our recognition of revenues from product orders which can
      materially affect our operating results on a quarterly basis due to the
      size of a particular order.

PLANNED GROWTH OF OUR BUSINESS WILL STRAIN ON OUR FINANCIAL, MANAGEMENT AND
PRODUCTION RESOURCES.

    In order to grow, we must expand our manufacturing capacity by adding
additional production machines, which will place a strain on our financial
resources. We spent approximately $23.5 million in capital expenditures in 1999
and anticipate that we will spend approximately $17.0 million in capital
expenditures in 2000. Our proceeds from this offering will not be sufficient to
meet all of our anticipated needs for capital expenditures and working capital.
Accordingly, we will need to finance a large portion of these future
expenditures through external sources, including borrowings. Currently, we do
not have sufficient credit facilities in place to provide this financing. We
cannot assure you we will be able to secure credit facilities or other sources
of financing that will address our future capital needs, or that such credit
facilities will be on terms as favorable to us as we have budgeted.

    In addition, growth of our business will increase the work load and
responsibilities of our existing management and require us to expand our
management team. We cannot assure you that the present

                                       4
<PAGE>
size of our management team will enable us to expand our business or that we
will be able to recruit enough experienced managers.

    Most of our products are manufactured by a limited number of production
machines that are currently running at or near capacity. We do not have plans to
develop redundancy for much of our production capability. Therefore, a breakdown
or damage to certain machines would severely and adversely affect our business.
In addition, it can take up to 12 to 18 months to replace a production machine.
If we do not implement our plans to expand our manufacturing capacity on a
timely basis, we could face production shortfalls. Further, if we rapidly
increase production, we may experience decreased manufacturing yields, which may
lower our margins.

WE MAY NOT BE ABLE TO BRING NEW MACHINES ONLINE EFFECTIVELY IN OUR MANUFACTURING
OPERATIONS TO MEET INCREASING CAPACITY REQUIREMENTS.

    We are expanding our manufacturing capacity through the purchase of two new
productions machines for our Tempe facility in 1999, one of which began
production in the first quarter of 2000 and the other of which is scheduled to
begin production in early 2001. In addition, we expect the first machine in our
new Dresden manufacturing facility to begin commercial production in the third
quarter of 2000 and the second to begin production in the first quarter of 2001.
In the past, we have experienced significant problems during the start-up of new
machines. In particular, we recorded substantial write-offs of inventory and
incurred substantial expenses in connection with the resolution of these
problems for PM 5 in Tempe. If we encounter similar problems with new machines,
our production capability and our operating results will suffer.

WE DEPEND ON A SMALL NUMBER OF CUSTOMERS FOR A SUBSTANTIAL PORTION OF OUR SALES,
AND THE LOSS OF A LARGE CUSTOMER COULD HURT OUR REVENUES OR OPERATING RESULTS.

    Our ten largest customers accounted for approximately 64.2%, 74.2%, 69.2%
and 79.5% of net product sales in 1997, 1998, 1999 and the first quarter of
2000, respectively. In the first quarter of 2000, one customer in the electronic
display market, with which we have no long term contract, accounted for
approximately one-third of our revenues. We expect to continue to derive a
significant portion of our net product sales from a relatively small number of
customers. Accordingly, the loss of a large customer could materially hurt our
business, and the deferral or loss of anticipated orders from a small number of
customers could materially damage our revenue and operating results in any
period. In addition, we do not have long-term contracts or purchase orders with
most of our customers, and customers may cancel their orders, change production
quantities from forecast volumes, request that we defer production or delay
payment for any reason.

WE DEPEND ON OUR OEM CUSTOMERS FOR THE SALE OF OUR PRODUCTS AND FOR INFORMATION
RELATING TO THE DEVELOPMENT OF NEW PRODUCTS.

    We sell a substantial portion of our products to a relatively small number
of original equipment manufacturers, or OEMs. The timing and amount of sales to
these customers ultimately depend on sales levels and shipping schedules for the
OEM products into which our products are incorporated. We have no control over
the shipping dates or volume of products shipped by our OEM customers, and we
cannot be certain that our OEM customers will continue to ship products that
incorporate our products at current levels or at all. Failure of our OEM
customers to achieve significant sales of products incorporating our products
and fluctuations in the timing and volume of such sales could be harmful to our
business. Failure of these customers to inform us of changes in their production
needs in a timely manner could also hinder our ability to effectively manage our
business.

    In addition, we rely on our OEM customers to inform us of opportunities to
develop new products that serve end-user demands. If our OEM customers do not
present us with market opportunities early

                                       5
<PAGE>
enough for us to develop products to meet end-user needs in a timely fashion, or
if the OEMs fail to anticipate end-user needs at all, we may fail to develop new
products or modify our existing products for our end-user markets. In addition,
if our OEM customers fail to accurately anticipate end-user demands, we may
spend resources on products that are not commercially successful.

WE ARE DEPENDENT ON KEY SUPPLIERS OF MATERIALS WHICH MAY PREVENT US FROM
DELIVERING PRODUCT IN A TIMELY MANNER.

    We manufacture all of our products using materials procured from third-party
suppliers. Certain of these materials are obtained from a limited number of
sources. For example, the substrates we use in the manufacture of our Heat
Mirror product is only currently available from one qualified source, Teijin
Limited, holder of approximately 8.1% of our common stock. The substrates used
in the manufacture of our anti-reflective film are currently available from only
two qualified sources, Teijin and Di Nippon Printing. The loss of either of
these current sources could adversely affect our ability to meet our scheduled
product deliveries to customers. In addition, any interruption in the operations
of vendors of certain other materials could also adversely affect our ability to
meet our scheduled product deliveries to customers. If we are unable to obtain a
sufficient supply of materials from our current sources, we could experience
difficulties in obtaining alternative sources quickly or in altering product
designs to use alternative materials. In the case of several materials, it
generally takes several months to qualify new suppliers. Delays or reductions in
product shipments could damage our relationships with customers. Further, a
significant increase in the price of one or more of the materials used in our
products could have a material adverse effect on our operating results.

WE ARE DEPENDENT ON A LIMITED NUMBER OF MANUFACTURERS OF OUR PRODUCTION MACHINES
WHICH MAY PREVENT US FROM DELIVERING PRODUCT ON A TIMELY BASIS.

    Our production machines are large, complex and difficult to manufacture. It
can take up to a year from the time we order a machine until it is delivered.
Following delivery, it can take us, with the assistance of the manufacturer, up
to six additional months to test and prepare the machine for commercial
production. There are a very limited number of companies that are capable of
manufacturing these machines to our specifications. Our inability to have new
production machines manufactured and prepared for commercial production in a
timely manner would have a material adverse effect on our business.

WE MUST CONTINUE TO DEVELOP NEW PRODUCTS AND ENHANCE EXISTING PRODUCTS ON A
TIMELY BASIS TO COMPETE SUCCESSFULLY IN A RAPIDLY CHANGING MARKETPLACE.

    The market for thin-film coated glass and coating equipment is characterized
by rapid change, especially in the electronic display market. Our future success
depends upon our ability to introduce new products, improve existing products
and processes to keep pace with technological and market developments, and to
address the increasingly sophisticated and demanding needs of our customers.
Technological changes, process improvements, or operating improvements that
could adversely affect us include:

    - the development of new technologies that improve the manufacturing
      efficiency of our competitors;

    - changes in product requirements of our customers;

    - changes in the way coatings are applied to alternative substrates such as
      tetra acetate cellulose, or TAC;

    - the development of new materials that improve the performance of thin-film
      coated glass; and

    - improvements in the alternatives to the sputtering technology we use to
      produce our products.

                                       6
<PAGE>
    We may not have sufficient funds to devote to research and development, or
our research and development efforts may not be successful in developing
products in the time, or with the characteristics, necessary to meet customer
needs. If we do not adapt to technological changes, or process or operating
improvements, our competitive position, operations and prospects would be
materially adversely affected.

WE FACE INTENSE COMPETITION, WHICH COULD AFFECT OUR ABILITY TO INCREASE OUR
REVENUE, MAINTAIN OUR MARGINS AND INCREASE OUR MARKET SHARE.

    The market for each of our products is intensely competitive and we expect
competition to increase in the future. Competitors vary in size and in the scope
and breadth of the products they offer. Many of our current and potential
competitors have significantly greater financial, technical, marketing and other
resources than we have. In addition, many of our competitors have
well-established relationships with our current and potential customers and have
extensive knowledge of our industry. Current and potential competitors have
established or may establish cooperative relationships among themselves or with
third parties to increase the ability of their products to address customer
needs.

    ELECTRONIC DISPLAY MARKET.  Competitors in the anti-reflective coatings
market include customers who have the capability to use wet coating technology,
as well as competitors who supply sputter coated films similar to those produced
by us. One of the largest manufacturers of flat-face computer display tubes, or
CDTs, Sony Corporation, has its own sputter coating film technology which it
uses to provide anti-reflective characteristics on CDTs.

    AUTOMOTIVE GLASS MARKET.  Solar control products in the automotive OEM
market are provided by large, worldwide glass laminators who typically have
divisions also selling products to the commercial flat glass industry. Several
of these companies, such as PPG, Pilkington PLC, Sekurit St. Gobain, Asahi,
Guardian, and Glaverbel, have direct to glass sputtering capability. In the
applied film segment of the automotive market, companies such 3M, Material
Sciences Corporation, CP Films, and Courtaulds PLC produce competitive solar
control products that are widely accepted in the market.

    RESIDENTIAL AND COMMERCIAL WINDOW MARKET.  Since our introduction of our
Heat Mirror suspended film product in 1979, large glass producers such as
Guardian, PPG, Viracon, Glaverbel, and Asahi, have produced their own
direct-to-glass sputtered products that provide solar control and energy
conservation similar to our Heat Mirror product.

OUR ABILITY TO SERVICE OUR BORROWINGS AND MAINTAIN CREDIT FACILITIES WILL DEPEND
UPON OUR FUTURE CASH FLOWS AND COVENANT COMPLIANCE.

    We have financed a large portion of our capital expenditures through
borrowings and expect to continue to do so. Our inability to make timely
payments of interest or principal under these facilities due to fluctuations in
our cash flow or otherwise, could materially adversely affect our ability to
borrow money under existing credit facilities or to secure additional
borrowings. In addition, our current credit facilities contain, and our future
credit facilities will contain, financial and operating covenants that will
limit our discretion with respect to business matters. Among other things, these
covenants may restrict our ability to incur additional indebtedness, create
liens or other encumbrances, and make certain payments including dividends and
capital expenditures. These credit facilities also contain financial covenants
and events of default that could require us to pay off indebtedness before its
maturity. The restrictions imposed by these credit facilities or the failure of
lenders to advance funds under these facilities could adversely affect our
ability to fund our growth.

                                       7
<PAGE>
IF WE FAIL TO RECRUIT AND RETAIN A SIGNIFICANT NUMBER OF QUALIFIED TECHNICAL
PERSONNEL, WE MAY NOT BE ABLE TO DEVELOP, ENHANCE AND INTRODUCE OUR PRODUCTS ON
A TIMELY BASIS, AND OUR BUSINESS WILL BE HARMED.

    We require the services of a substantial number of qualified technical
personnel. The market for skilled technical personnel is characterized by
intense competition and aggressive recruiting, as well as a high-level of
employee mobility. These characteristics make it particularly difficult for us
to attract and retain the qualified technical personnel we require. We have
experienced, and we expect to continue to experience, difficulty in hiring and
retaining highly skilled employees with appropriate technical qualifications. It
is especially difficult for us to recruit qualified personnel to work in Palo
Alto because of the high-cost of living. If we are unable to recruit and retain
a sufficient number of qualified technical employees, we may not be able to
complete the development of, or enhance, our products in a timely manner. As a
result, our business may be harmed and our operating results may suffer.

WE MAY BE UNABLE TO ATTRACT OR RETAIN THE OTHER HIGHLY SKILLED EMPLOYEES THAT
ARE NECESSARY FOR THE SUCCESS OF OUR BUSINESS.

    In addition to our dependence on our technical personnel, our success also
depends on our continuing ability to attract and retain other highly skilled
employees. We depend on the continued services of our senior management,
particularly Thomas G. Hood, our President and Chief Executive Officer, and Bill
R. Finley, our Chief Financial Officer. We do not have key person life insurance
covering any officer or employee. Competition for personnel in our industry
where we operate is intense. We have experienced, and we expect to continue to
experience, difficulty in hiring and retaining highly skilled employees with
appropriate qualifications. If we do not succeed in attracting or retaining the
necessary personnel, our business could be adversely affected.

WE MAY NOT BE ABLE TO PROTECT OUR INTELLECTUAL PROPERTY.

    Our success depends in large part upon our proprietary technology. We rely
on our know-how, as well as a combination of patent, trademark and trade secret
protection, to establish and protect our intellectual property rights. We seek
to avoid disclosure of our know-how and trade secrets through a number of means,
including requiring those persons with access to our proprietary information to
execute nondisclosure agreements with us. We also seek to protect our
technology, documentation and other written materials under trade secret and
copyright laws, which afford only limited protection. Some foreign countries in
which we do business afford significantly less protection for intellectual
property than the United States.

    Despite our efforts to protect our proprietary rights, unauthorized parties
may attempt to copy aspects of our products or to obtain and use information
that we regard as proprietary. Policing unauthorized use of our products is
difficult and our means of protecting our proprietary rights may not be
adequate. In addition, our competitors may independently develop similar
technology, duplicate our products, or design around our proprietary
intellectual property.

OUR BUSINESS IS SUSCEPTIBLE TO NUMEROUS RISKS ASSOCIATED WITH INTERNATIONAL
OPERATIONS.

    We have expanded our operations and hired additional personnel to address
international markets for the thin-film coatings industry. International
revenues amounted to approximately 65%, 68%, 77% and 84% of our net revenues
during 1997, 1998, 1999 and the three months ended April 2, 2000, respectively.
To achieve acceptance in international markets, our products must be modified to
handle a variety of factors specific to each international market as well as
local regulations. We may also be subject to a number of other risks associated
with international business activities. These risks include:

    - unexpected changes in and the burdens and costs of compliance with a
      variety or foreign laws and regulatory requirements;

                                       8
<PAGE>
    - currency exchange rate fluctuations;

    - tariffs and other trade barriers;

    - longer accounts receivable payment cycles and difficulties in collecting
      accounts receivable;

    - difficulties in managing and staffing international operations;

    - potentially adverse tax consequences, including restrictions on the
      repatriation of earnings; and

    - global economic turbulence and political instability.

WE EXPECT TO BE SUBJECT TO INCREASED FOREIGN CURRENCY RISK IN OUR INTERNATIONAL
OPERATIONS.

    Our international sales are currently invoiced and collected in U.S.
dollars. A strengthening in the dollar relative to the currencies of those
countries in which we do business would increase the prices of our products as
stated in those currencies and could hurt our sales in those countries.
Significant fluctuations in the exchange rates between the U.S. dollar and
foreign currencies could cause us to lower our prices and thus reduce our
profitability. These fluctuations could also cause prospective customers to
delay orders because of the increased relative cost of our products.

    We expect that, within the next twelve months, the customers of our Dresden
operation will begin to make payments in euros or other foreign currencies. In
addition, in the future, other of our customers may also make payments in
foreign currencies. Accepting payments in foreign currency may require us to
begin to hedge these currencies in order to reduce the risk to us of fluctuating
exchange rates.

PERFORMANCE, RELIABILITY OR QUALITY PROBLEMS WITH OUR PRODUCTS MAY CAUSE OUR
CUSTOMERS TO REDUCE OR CANCEL THEIR ORDERS.

    We manufacture our electronic display and automobile glass products based on
specific, technical requirements of each of our customers. We believe our
ability to obtain future orders of our products will depend on our maintenance
of the performance, reliability and quality standards our customers require. If
our products have performance, reliability or quality problems, then we may
experience:

    - delays in collecting accounts receivable;

    - higher manufacturing costs;

    - additional warranty and service expenses; and

    - reduced or cancelled orders.

WE MAY FACE COSTLY DAMAGES OR LITIGATION COSTS IF A THIRD PARTY CLAIMS THAT WE
INFRINGE ITS INTELLECTUAL PROPERTY.

    Third parties may claim that we or our current or potential future products
infringe upon their intellectual property. Any claims, with or without merit,
could be time consuming, result in costly litigation, cause product shipment
delays or require us to enter into royalty or licensing agreements. Royalty or
licensing agreements, if required, may not be available on terms acceptable to
us or at all, which could seriously harm our business.

IF WE FAIL TO COMPLY WITH ENVIRONMENTAL REGULATIONS, OUR OPERATIONS COULD BE
ADVERSELY AFFECTED.

    We use hazardous chemicals in producing our products. As a result, we are
subject to a variety of local, state and federal governmental regulations
relating to the storage, discharge, handling, emission, generation, manufacture
and disposal of toxic or other hazardous substances, compliance with which is
expensive. Our failure to comply with current or future environmental
regulations could result in the

                                       9
<PAGE>
imposition of substantial fines on us, suspension of production, alteration of
our manufacturing processes or cessation of operations. Compliance with these
regulations also may require us to acquire costly equipment or to incur other
significant expenses.

WE RELY ON OUR INTERNATIONAL AND DOMESTIC SALES REPRESENTATIVES, WITHOUT WHOM
OUR SALES MAY SUFFER.

    We sell our products in Japan, China and Korea through sales
representatives. We also market and sell our Heat Mirror products in North
America primarily through sales representatives. These sales representatives
could reduce or discontinue sales of our products. They may not devote the
resources necessary to provide effective sales and marketing support to us. In
addition, we depend upon the continued viability and financial resources of
these representatives, many of which are small organizations with limited
working capital. These representatives, in turn, depend substantially on general
economic conditions and other factors affecting the markets for the products
they sell. We believe that our success will continue to depend upon these sales
representatives. If some or all of our sales representatives experience
financial difficulties, or otherwise become unable or unwilling to promote and
sell our products, our business could be harmed.

                         RISKS RELATED TO THIS OFFERING

THE PRICE OF OUR COMMON STOCK AFTER THIS OFFERING MAY BE LOWER THAN THE PRICE
YOU PAY.

    If you purchase shares of our common stock in this offering, you will pay a
price that we negotiated with the representative of the underwriters. The price
of our common stock that will prevail in the market after this offering may be
higher or lower than the price you pay in this offering. See "Underwriting."

OUR STOCK PRICE COULD FLUCTUATE WIDELY IN RESPONSE TO VARIOUS FACTORS, MANY OF
WHICH ARE BEYOND OUR CONTROL.

    The trading price of our common stock may be highly volatile. Our stock
price could fluctuate widely in response to factors such as the following:

    - actual or anticipated variations in our quarterly revenues or operating
      results;

    - announcements of new products or services by us or our competitors, or new
      competing technologies;

    - our addition or loss of significant customers;

    - changes in financial estimates or recommendations by securities analysts;

    - our announcement of significant acquisitions or strategic partnerships;

    - discussions about us in internet chat rooms;

    - additions or departures of our key personnel;

    - future equity or debt offerings by us or our announcements of such
      offerings; and

    - general market and economic conditions.

    In addition, in recent years the stock markets in general, and the Nasdaq
National Market and the market for technology companies in particular, have
experienced large price and volume fluctuations. These fluctuations have often
been seemingly unrelated or disproportionate to the operating performance of
these technology companies. These market and industry factors may materially and
adversely affect our stock price, regardless of our operating performance. In
the past, securities class action litigation has often been brought against a
company following periods of volatility in the market price of its stock. We may
in the future be the target of similar litigation. Securities litigation could

                                       10
<PAGE>
result in substantial costs or large judgments against us and divert
management's attention and resources.

CERTAIN PROVISIONS OF OUR CHARTER, BY-LAWS AND DELAWARE LAW MAKE A TAKEOVER
DIFFICULT.

    Certain provisions of our corporate charter and by-laws and Delaware law,
might discourage, delay or prevent a change of control or a change in our
management, even if such changes would be beneficial to our stockholders. These
provisions include the ability of our board of directors, without stockholder
approval, to issue any class or series of preferred stock with dividend rights,
dividend rates, conversion rights, redemption rights, preferences on liquidation
or dissolution, voting rights and any other preferences, which could adversely
affect the voting and other rights of the holders of common stock. These
provisions could also discourage proxy contests and make it more difficult for
you and other stockholders to elect directors and take other corporate actions.
The existence of these provisions could limit the price that investors might be
willing to pay for shares of our common stock and could deprive you of an
opportunity to receive a premium for your common stock as part of a sale of
Southwall. See "Description of Capital Stock."

THE MARKET PRICE OF OUR COMMON STOCK MAY DROP SIGNIFICANTLY WHEN THE
RESTRICTIONS ON RESALE BY OUR EXISTING SECURITYHOLDERS LAPSE.

    Following this offering, we will have approximately 10.4 million shares of
common stock outstanding. Holders of       shares have agreed not to sell these
shares for at least 180 days following the date of this prospectus. As these
restrictions on resale end, the market price of our common stock could drop
significantly if holders of these shares sell them or if the market perceives
they intend to sell them. These sales also may make it difficult for us to sell
equity securities in the future at a time and price that we deem appropriate.
See "Shares Eligible for Future Sale."

    We estimate our net proceeds from the sale of 2,500,000 shares of common
stock that we are offering by means of this prospectus will be approximately
$24.2 million, at an assumed public offering price of $10.50 per share, after
deducting estimated underwriting discounts and commissions, and offering
expenses. If the underwriters' over-allotment option is exercised in full, we
estimate our net proceeds will be approximately $28.6 million. We will not
receive any proceeds from the sale of shares by the selling stockholders.

    We intend to use our net proceeds from this offering as follows:

    - approximately $10.0 million to repay the outstanding balance on our bank
      line of credit, which bears interest at the lender's prime rate (which was
      9.5% on June 14, 2000) plus 1% per annum, and matures in June 2001;

    - approximately $5.0 million to repay bank debt, which bears interest at the
      London Interbank Offer Rate (which was 6.81% on June 14, 2000) plus
      0.4375% per annum, and, as a result of such repayment, matures in November
      2001; and

    - the balance for funding of working capital and capital expenditures.

    We entered into our current bank line of credit in June 2000. This line
replaced our prior line, which we entered in June 1999. We borrowed
approximately $2.7 million to repay senior subordinated indebtedness and
approximately $1.0 million to fund the initial capitalization of our German
subsidiary under our prior line, and used the remaining formerly outstanding
balance for working capital purposes.

    While the amounts indicated above reflect what we currently expect to spend
on these matters, opportunities may arise that cause us to change the allocation
of proceeds. Pending these proposed uses, we intend to invest our net proceeds
from this offering in short-term, interest-bearing, investment-grade securities,
certificates of deposit or direct or guaranteed obligations of the United
States.

                                DIVIDEND POLICY

    We have never declared or paid any cash dividends on our common stock, and
we do not anticipate paying cash dividends in the foreseeable future. We
currently intend to retain future earnings, if any, to fund the expansion and
growth of our business. In addition, our current bank line of credit limits our
ability to pay cash dividends or make other distributions on our common stock.
Payment of future cash dividends, if any, will be at the discretion of our board
of directors after taking into account various factors, including our financial
condition, operating results, current and anticipated cash needs and plans for
expansion.

                                 CAPITALIZATION

    The following table sets forth our capitalization as of April 2, 2000:

    - on an actual basis; and

      of $10.50 per share, after deducting estimated underwriting discounts and
      commissions and estimated offering expenses payable by us.

    This information should be read in conjunction with our consolidated
financial statements and notes thereto, appearing elsewhere in this prospectus.
This information excludes 1,406,159 shares, which consist of:

    - 1,059,700 shares subject to outstanding options under our 1997 stock
      incentive plan, with a weighted average exercise price of $5.26 per share;
      and

    - 346,459 shares subject to outstanding options under our 1998 stock option
      plan for employees and consultants, with a weighted average exercise price
      of $5.59 per share.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

    THE FOLLOWING DISCUSSION AND ANALYSIS OF OUR FINANCIAL CONDITION AND RESULTS
OF OPERATIONS SHOULD BE READ IN CONJUNCTION WITH "SELECTED CONSOLIDATED
FINANCIAL DATA" AND OUR CONSOLIDATED FINANCIAL STATEMENTS AND NOTES THERETO
APPEARING ELSEWHERE IN THIS PROSPECTUS. THIS DISCUSSION AND ANALYSIS CONTAINS
FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND UNCERTAINTIES. YOU SHOULD NOT
PLACE UNDUE RELIANCE ON THESE FORWARD-LOOKING STATEMENTS. OUR ACTUAL RESULTS MAY
DIFFER MATERIALLY FROM THOSE ANTICIPATED IN THESE FORWARD-LOOKING STATEMENTS AS
A RESULT OF CERTAIN IMPORTANT FACTORS, INCLUDING, BUT NOT LIMITED TO, THOSE SET
FORTH UNDER "RISK FACTORS" ON PAGE 4 OF THIS PROSPECTUS.

OVERVIEW

    We are a leading designer and manufacturer of technologically advanced
thin-film coatings that selectively absorb, reflect or transmit light and
electromagnetic and infrared emissions. Our products are used in a number of
electronic, automotive and building products to enhance optical and thermal
performance characteristics, improve user comfort and reduce energy costs. From
our founding in 1979 through the early 1990's, we developed and produced
thin-film coated substances primarily for residential and commercial buildings,
and for military applications. In the early 1990's, we began to develop products
for the electronic display and automotive markets.

    In 1996, we realized our first material revenue from the electronic display
and automotive markets. Currently electronic display products account for almost
one half of our revenues. We expect most of our revenue growth to continue to
come from the electronic display and automotive markets. In 1999, international
revenues accounted for approximately 77% of our net revenues.

    Several factors affect our gross margins, including manufacturing
efficiencies, product mix, product differentiation, inventory management, volume
pricing, and the start-up of equipment and new plants. Over the past several
years, each of these factors has contributed to margin volatility as we have
added new capacity to meet the demand of our electronics and automotive markets.
As new capacity is brought to full commercial operation, we believe we will be
able to maintain or improve our operating margins.

CAPITAL EXPENDITURES

    In 1999, we invested approximately $23.5 million in capital expenditures
primarily to meet anticipated higher demand for our electronic display and
automotive products. In 2000, we expect to spend approximately $17.5 million for
capital expenditures to increase production capacity in our Tempe and new
Dresden operations. From the time we order a new production machine, it
typically takes 12 to 18 months until we are able to produce in commercial
volumes. The last six months of this period are typically spent testing the
machine to make sure it meets our product quality requirements and those of our
customers. During this period the new production machines typically produce
minimal revenues. In accordance with generally accepted accounting principles,
all substrate, target and material costs incurred prior to a machine beginning
any commercial production are expensed as incurred and classified as costs of
sales. In addition, interest costs associated with borrowings for capital
expenditures are capitalized until these assets begin commercial production
commences.

    In the first quarter of 2000, our second machine at Tempe (PM 6) began to
produce limited amounts of film for commercial use. We ordered an additional
machine (PM 7) for delivery to Tempe in the second quarter of 2000. This
production machine is expected to commence commercial production in the first
half of 2001. Additionally, we took possession of our new facility in Dresden in
May 2000, which will contain two new production machines (PM 8 and PM 9). We
expect these two production machines to commence commercial production in the
second half of 2000 and the first half of 2001, respectively.

    In general, we have experienced significant start-up costs in connection
with bringing new production machines into commercial viability. In 1998, our
operating results were adversely affected by quality problems associated with
the electronic display film product produced by a new production machine (PM 5)
in Tempe. In the fourth quarter of 1998, we discovered quality issues with
product that had been shipped to Sony and other electronic display film that was
still in inventory in Tempe that did not meet Sony's specifications. We recorded
a $4.0 million provision in the fourth quarter of 1998 to account for product
returns from Sony and the related write-off of inventory. During 1999, we
continued to experience ongoing production problems with the Sony electronic
display film. In March 1999, we amended the terms of the supply agreement to
eliminate purchase and supply requirements. Sales to Sony through the first
three quarters of 1999 declined significantly. We discontinued the manufacture
and sale of coated anti-reflective film to Sony in September 1999.

    Due to the unprofitable relationship with Sony and our increased capital
expenditures, we have been operating with minimal cash balances. We have been
using cash available from operations, German government grants, bank borrowings
and other long-term debt to finance our increased capital expenditures.

QUARTER ENDED APRIL 4, 1999 COMPARED WITH THE QUARTER ENDED APRIL 2, 2000

NET REVENUES

    Net revenues increased $6.7 million, or 62.5%, from $10.9 million for the
first three months of 1999 to $17.6 million for the first three months of 2000.
This increase in net revenues was partially offset by a decrease of
$0.7 million in sales of our automotive glass products. During the first quarter
of 1999, our Tempe facility had minimal production as a result of the
re-certification of production processes for product provided to Sony. Following
the September 1999 termination of our relationship with Sony, the Tempe
production machine was converted to the production of a similar anti-reflective

                                       18
<PAGE>
product for new customers. The increase in net revenues was primarily
attributable to a $7.4 million increase in sales of electronic display films,
primarily due to the successful yield improvements in our production machines
located in Palo Alto and Tempe.

COSTS AND EXPENSES

    COST OF SALES.  Cost of sales expense consists primarily of materials,
production labor and machine overhead. Cost of sales increased $3.4 million, or
38.2%, from $8.9 million in the first quarter of 1999 to $12.3 million for the
similar period of 2000. As a percentage of net revenues, cost of sales decreased
from 82.1% of net revenues in the first quarter of 1999, to 69.8% of net
revenues for the similar period of 2000. The percentage reduction in cost of
sales was due to improved yields and increased machine throughput of electronic
display films during the first quarter of 2000. Cost of sales also improved in
the recent period due to the return to commercial production of PM 5 which had
been shut down for product re-certification in the first quarter of 1999.

    RESEARCH AND DEVELOPMENT.  Our research and development spending increased
$0.3 million, or 22.5%, from $1.2 million in the first quarter of 1999 to
$1.5 million in the first quarter of 2000. Research and development expenses
decreased from 11.4% of net revenues for the first three months of 1999, to 8.6%
of net revenues for the similar period in 2000. The increase in the first
quarter of 2000 was primarily attributable to additional travel and personnel
costs associated with supporting installation of the new production machines in
the Tempe and Dresden plants. In addition, we incurred additional costs during
the first quarter of 2000 in the development of a prototype antenna and a
heatable windshield for automobiles using our XIR films.

    SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative
expenses consist primarily of corporate and administrative overhead, selling
commissions, advertising costs and occupancy costs. These expenses increased
$0.4 million, or 22.7%, from $2.0 million in the first quarter of 1999 to
$2.4 million in the first quarter of 2000. Selling, general and administrative
expenses decreased from 18.1% of net revenues for the first three months of
1999, to 13.7% of net revenues for the similar period of 2000. The $0.4 million
increase in the first three months of 2000 was primarily related to our hiring
of additional sales personnel and preparation of marketing materials to support
our higher planned production capacities. Additionally, travel and communication
expenses also increased as the additional sales personnel devoted themselves to
international sales.

INCOME (LOSS) FROM OPERATIONS.

    Income from operations increased $2.7 million from a loss of $1.3 million
for the first quarter of 1999 to a profit of $1.4 million for the comparable
period in 2000. The return to profitability was primarily a result of PM 5's
return to full commercial production.

INTEREST INCOME (EXPENSE), NET.

    Net interest expense increased $0.2 million from $0.3 million for the first
quarter of 1999 compared to $0.5 million for the similar period in 2000.
Interest expense increased from 1999 due to an increase in borrowings from debt
and bank credit lines at a higher average annual interest rate.

INCOME (LOSS) BEFORE PROVISION FOR INCOME TAXES.

    We reported a pre-tax loss of $1.5 million for the first quarter of 1999,
compared to pre-tax income of $0.9 million for the corresponding period in 2000.
The return to profitability was primarily a result of PM 5's resumption of full
commercial production.

FISCAL 1998 COMPARED TO FISCAL 1999

NET REVENUES

    Net revenues increased $5.3 million, or 10.6%, from $50.0 million in 1998,
to $55.3 million in 1999. In 1999, sales of electronic display products
decreased by $0.7 million. This decrease was the result of approximately
$4.4 million of lower sales from Sony and a $2.3 million provision for product
returns from Sony. The decrease was partially offset by an increase of
approximately $6.2 million of sales to new customers. Sales of our automotive
glass film increased $6.6 million, primarily due to the receipt of a significant
purchase order from a European automobile glass OEM. We made no sales to Sony
after September 30, 1999.

COSTS AND EXPENSES

    COST OF SALES.  Excluding the $1.7 million provision related to the product
produced for Sony, cost of sales decreased $2.8 million, or 6.3%, from
$44.3 million in 1998 to $39.8 million in 1999. Excluding the provision for
Sony, cost of sales for 1998 was 85.0% of net revenues compared to 71.9% of net
revenues for 1999. This decrease was primarily due to improved throughput and
yields of our products.

    RESEARCH AND DEVELOPMENT.  Total research and development expenses increased
$1.3 million, or 35.8%, from $3.9 million in 1998 to $5.2 million in 1999.
Research and development expenses, as a percentage of net revenues, increased
from 7.7% for 1998, to 9.5% for 1999. The increase in these expenses was
primarily attributable to costs associated with re-certifying PM 5 for
commercial production, the costs associated with retrofitting PM 1, and the
costs incurred to design and install two new production machines (PM 6 and
PM 8).

    SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative
expenses decreased $0.5 million, or 6.4%, from $9.0 million in 1998 to
$8.5 million in 1999. Selling, general and administrative expenses, as a
percentage of net revenues, decreased from 18.1% in 1998, to 15.3% in 1999. The
primary reason for the decrease in these expenses was the elimination of certain
positions related to the sales and service functions for after-market building
products. In 1999, we contracted with an independent distributor which agreed to
perform these functions.

INCOME (LOSS) FROM OPERATIONS.

    Income from operations increased $9.0 million from a loss of $7.1 million
for 1998 to a profit of $1.8 million for 1999. Increased income from operations
was primarily due to increased sales of automotive products, the adverse affect
on 1998 results of the provision for Sony and the discontinuance of unprofitable
sales of electronic display products to Sony.

INTEREST INCOME (EXPENSE), NET.

    Net interest expense increased $0.6 million from $0.7 million for 1998 to
$1.3 million for 1999, primarily due to our borrowing approximately
$7.5 million of additional debt and overall higher interest rates.

INCOME (LOSS) BEFORE PROVISION FOR INCOME TAXES

    We reported a pre-tax loss of $7.8 million for 1998, compared to pre-tax
income of $0.6 million for 1999. We attained profitability in 1999 primarily due
to the increase in sales of automotive products and the elimination of
unprofitable electronic display product sales.

FISCAL 1997 COMPARED TO FISCAL 1998

NET REVENUES

    Net revenues decreased by $0.1 million, or 0.1%, from $50.1 million in 1997
to $50.0 million in 1998. Sales of our automotive glass products in 1998
increased approximately $6.2 million from 1997. Sales to an OEM glass
manufacturer increased by $8.1 million, partially offset by a decrease of
$1.9 million in sales to GMX as a result of the economic recession in Asia.
Sales of our electronic display products in 1998 decreased by $5.0 million
primarily due to a reduction in sales to Sony of approximately $3.0 million and
a provision of $2.3 million related to the return of product from Sony. This
decrease was partially offset by sales to one new customer of approximately
$2.6 million.

COSTS AND EXPENSES

    COST OF SALES.  Cost of sales increased $10.5 million, or 25.5%, from
$35.3 million in 1997 to $44.3 million in 1998. As a percentage of net revenues,
cost of sales for 1997 was 70.5% compared to 88.4% for 1998. The increase was
primarily due to the write-off of anti-reflective film produced for Sony in 1998
and low yields on electronic display products manufactured for Sony in Tempe in
1998.

    RESEARCH AND DEVELOPMENT.  Research and development expenses increased by
$0.7 million, or 24.0%, from $3.1 million in 1997 to $3.9 million in 1998.
Research and development expenses, as a percentage of net revenues, increased
from 6.2% for 1997 to 7.7% for 1998. The increase was largely attributable to
the hiring of 19 additional research and development personnel to support
increased new product development, primarily in film for new electronic display,
laminated automotive and Solis products.

    SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative
expenses decreased $0.2 million, or 1.8%, from $9.2 million in 1997 to
$9.0 million in 1998. As a percentage of net revenue, these expenses decreased
from 18.4% in 1997 to 18.1% in 1998. The decrease in these expenses was due to a
reduction in administrative personnel and cost control measures adopted in the
second half of 1998.

INCOME (LOSS) FROM OPERATIONS.

    Income from operations decreased $9.5 million from a profit of $2.4 million
for 1997 to a loss of $7.1 million for 1998. The principal reason for the loss
in 1998 was the $4.0 million provision for products produced for Sony and low
production yields associated with the manufacture of electronic display product
for Sony.

INTEREST INCOME (EXPENSE), NET.

    Net interest expense increased from an immaterial amount in 1997 to
$0.7 million for 1998 primarily due to higher average outstanding borrowings in
1998.

INCOME (LOSS) BEFORE PROVISION FOR INCOME TAXES.

    We reported pre-tax income of $2.4 million for 1997, compared to a pre-tax
loss of $7.8 million for 1998. The principal reason for the loss in 1998 was the
$4.0 million provision for products produced for Sony and low production yields
associated with the manufacture of electronic display product for Sony.

    For the quarter ended December 27, 1998 we recorded a $4.0 million provision
to account for $2.3 million of product returns from Sony and $1.7 million for
the related write-off of inventory.

LIQUIDITY AND CAPITAL RESOURCES

LIQUIDITY

    Since 1998, we have funded our operations from cash provided by operating
activities. Working capital at December 31, 1999 was $3.0 million, which
increased to $5.6 million at April 2, 2000. We expect working capital to
increase after the offering and, primarily due to our anticipated capital
expenditures discussed below, further expect working capital to decrease to a
level slightly above our current level in the year following this offering.

    Operating activities generated approximately $4.3 million in both 1998 and
1999. Cash used in operating activities for the three month period ended
April 2, 2000 was approximately $4.8 million. This decrease in comparison to the
amount of cash used in operating activities for the similar period of 1999 was
primarily due to receivables and inventory growth to support increased sales of
electronic display products. Capital expenditures were approximately
$7.2 million, $23.5 million and $3.5 million for 1998, 1999 and the first
quarter of 2000, respectively.

(1) We recently obtained a new bank credit line of $10.0 million to replace the
    credit line in place at April 2, 2000. The new line bears interest at the
    rate of prime (9.5% at June 14, 2000) plus 1%. The line will expire in June
    2001 and is secured by receivables, inventory and other assets not otherwise
    collateralized. We expect that we will borrow up to the full amount
    available under the new line prior to the closing of this offering and apply
    a portion of the proceeds from this offering to repay that amount.

(2) We are required to make 48 equal monthly payments through December 2000.

(3) We are required to make equal semi-annual repayments from November 2000
    through November 2002. Prepayments of principal will be applied in reverse
    order of maturity.

(4) We are required to make equal monthly principal payments over the 36 month
    term of this financing.

(5) We are required to make equal monthly principal payments over the 24 month
    term of this financing.

(6) We are required to make equal semi-annual principal payments beginning ten
    years from the date of the loan through May 2019.

(7) We are required to make equal semi-annual principal payments beginning five
    years from the date of the loan through May 2009.

    Our bank line of credit subjects us to financial and other covenants,
including covenants related to our tangible net worth, our total liabilities to
tangible net worth, our profitability and the ratio of our current assets to
current liabilities. We have granted the lender a security interest in our
receivables, inventory and other assets not otherwise collateralized. Our loans
from German banks also subject us to covenants, including covenants relating to
the progress of the development of our Dresden facility and the minimum number
of our employees at Dresden by 2003. We have granted the German banks security
interests in our Dresden facility and the assets located at the facility.

    The promissory note dated December 16, 1996 is payable to a leasing company.
The borrowings are collateralized by certain production equipment and subject us
to certain financial covenants. At April 2, 2000, we were not in compliance with
certain of these financial covenants. We received a waiver from the leasing
company for failure to comply with these covenants through the remaining term of
the loan.

                                       23
<PAGE>
    The promissory note dated May 6, 1997 is payable to a bank and guaranteed by
Teijin Limited, a stockholder and one of our suppliers. The Teijin guarantee is
secured by PM 5 and our inventory to the extent necessary to cover 120% of the
outstanding loan balance based on the net book value of the inventory. The
guarantee subjects us to certain financial and other covenants, including
covenants relating to our tangible net worth, our debt to tangible net worth,
and the ratio of our cash, cash equivalents and short term investments to our
total current liabilities. At April 2, 2000, we were not in compliance with the
financial covenants relating to the ratio of our debt to equity and the ratio of
our cash, cash equivalents and short term investments to current liabilities.
Teijin delivered to us a waiver of these covenants at April 2, 2000 and through
July 2, 2001.

    We have provided the lessor under our sales-leaseback financings a
$0.5 million irrevocable standby letter of credit to collateralize our
obligations under the sales-leaseback agreements. The letter of credit will not
expire before January 1, 2002. In addition, $1.0 million of the amount received
from the lessor is in an escrow account and will be released upon our meeting
certain financial conditions.

CAPITAL EXPENDITURES

    Since 1998, we have used borrowings, German government grants and cash from
operations to fund our capital expenditures. During 1999, we invested
approximately $23.5 million in capital expenditures, including approximately
$9.8 million of progress payments for our new manufacturing facility and first
production machine (PM 8) in Dresden, approximately $7.5 million for two new
production machines (PM 6 and PM 7) and leasehold improvements for our Tempe
facility, and approximately $6.2 million for the upgrade of two production
machines (PM 1 and PM 2) in Palo Alto. These investments were financed by
$10.5 million of short and long term debt, $6.6 million in sales-leaseback
financings, $4.9 million in German government grants, and $4.3 million of cash
from operations. The German government grants subject us to a number of
covenants, including covenants that the proceeds be earmarked towards financing
our facility to manufacture film for the automotive glass industry in Dresden,
Germany, the total investment in our Dresden facility be at least
$37.6 million, our project create at least 150 jobs, and the construction be
completed by March 14, 2002. The German government may reclaim the grants if we
fail to meet any of the covenants. For the quarter ended April 2, 2000, we
invested approximately $3.5 million in capital expenditures, primarily to expand
production capacity in our Tempe manufacturing facility and to open and equip
our Dresden facility.

    We anticipate spending approximately $17.0 million for capital expenditures
in 2000, approximately $12.0 million of which will consist of final progress
payments on our two new production machines (PM 8 and PM 9) in Dresden and the
completion of our Dresden facility. We expect to finance our capital
expenditures in Germany primarily through the receipt of grants from the German
government, additional bank loans and the release of $3.1 million of cash
currently restricted by the German government to use in the financing the
completion of our Dresden facility.

    We expect to spend up to $5.0 million in capital expenditures primarily on
PM 7 and leasehold improvements at Tempe. We anticipate these expenditures will
be financed with an increased line of credit, cash generated from operations and
the proceeds of this offering.

    We expect our operating expenses to increase significantly, especially in
sales, marketing, and research and development. Although we do not have
sufficient credit facilities and government grants in place to cover all of our
operating needs, we currently anticipate that our existing capital resources,
borrowings, government grants and the proceeds from this offering will meet our
operating and investing needs for at least 18 months. After that time, we cannot
be certain that additional funding will be available on acceptable terms or at
all. If we require additional capital resources to grow our business, execute
our operating plans, or acquire complimentary technologies or businesses, we may

                                       24
<PAGE>
seek to sell additional equity or debt securities or secure additional lines of
credit, which may result in additional dilution to our stockholders.

QUALITATIVE AND QUANTITATIVE DISCLOSURE ABOUT MARKET RISK

FINANCING RISK

    Our exposure to market rate risk for changes in interest rates relates
primarily to our term loan, specifically our loan with Sanwa Bank, which is tied
to the London Interbank Offered Rate, and our bank line of credit that is tied
to an interest rate of the prime rate plus 1% per annum. Fluctuations in
interest rates may adversely affect our expected interest expense. Interest rate
fluctuations did not have a material impact on us in 1999.

INVESTMENT RISK

    We invest our excess cash in certificates of deposit and money market
accounts and, by policy, limit the amount of money invested with any one
institution. Investments in both fixed rate and floating rate interest earning
instruments carry a degree of interest rate risk. Fixed rate securities may have
their fair market value adversely impacted due to a rise in interest rates,
while floating rate securities may produce less income than expected if interest
rates fall.

FOREIGN CURRENCY RISK

    International revenues amounted to approximately 77% of our total sales in
1999 and, by policy, we have limited foreign currency risk by requiring all
sales to be denominated in U.S. dollars. However in the future, we may allow
customers of our Dresden operation to make payments for local sales in euros.
Our international business is subject to risks typical of an international
business, including, but not limited to differing economic conditions, changes
in political climate, differing tax structures, other regulations and
restrictions, and foreign exchange rate volatility. Accordingly, our future
results could be materially adversely impacted by changes in these or other
factors. Foreign exchange rate fluctuations did not have a material impact on us
in 1999. With respect to the local sale of products produced at our Dresden
facility, we expect to incur foreign currency risks and to begin to hedge
foreign currencies in response.

RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1998, the Financial Accounting Standards Board issued SFAS 133,
"Accounting for Derivative Instruments and Hedging Activities" (SFAS 133").
SFAS 133 was effective for all fiscal quarters beginning with the quarter ending
June 30, 1999. SFAS 133 establishes new standards of accounting and reporting
for derivative instruments, including certain derivative instruments embedded in
other contracts, and hedging activities. In July 1999, the Financial Accounting
Standards Board issued SFAS No. 137 "Accounting for Derivative Instruments and
Hedging Activities. Deferral of the Effective Date of FASB Statement No. 133"
("SFAS 137"). SFAS 137 deferred the effective date until the first fiscal
quarter ending June 30, 2000. The company does not currently hold derivative
instruments or engage in hedging activities.

    In December 1999, the Securities and Exchange Commission issued SAB
No. 101, "Revenue Recognition in Financial Statements," which provides guidance
on the recognition, presentation, and disclosure of revenue in financial
statements filed with the Securities and Exchange Commission. SAB No. 101
outlines the basic criteria that must be met to recognize revenue and provides
guidance for disclosures related to revenue recognition policies. SAB No. 101 is
effective for fiscal years beginning after December 15, 1999. We believe that
the adoption of SAB No. 101 will not have a material impact on our financial
position, results of operations or cash flow.

    In March 2000, the FASB issued FASB Interpretation No. 44 (FIN 44),
"Accounting for Certain Transactions involving Stock Compensation, an
interpretation of APB Opinion No. 25." FIN 44 clarifies the application of APB
Opinion No. 25 with respect to (a) the definition of employee for purposes of
applying Opinion No. 25, (b) the criteria for determining whether a plan
qualifies as a noncompensatory plan, (c) the accounting consequence for various
modifications to the terms of a previously fixed stock option or award, and
(d) the accounting for an exchange of stock compensation awards in a business
combination.

    FIN 44 is effective July 1, 2000, but certain of its conclusions cover
specific events that have occurred after either December 15, 1998, or
January 12, 2000. We believe the impact of FIN 44 will not have a material
effect on our financial position or results of operations.

                                    BUSINESS

    We are a leading developer, manufacturer and marketer of thin-film coatings
for the electronic display, automotive glass, and residential and commercial
building glass markets. Using our core thin-film sputtering technology, we have
developed a variety of products that reduce light reflection and improve image
quality in electronic display products, and conserve energy and control sunlight
in automotive and building glass products. Our products consist of
anti-reflective films for computer and television screens, including flat panel
and plasma displays, transparent conductive films for use in touch screen and
liquid crystal displays, transparent insulation and solar-control films for
automotive and building glass, and various other coatings.

INDUSTRY BACKGROUND

    Large area, single layer, thin-film coatings were developed in the early
1960s using vacuum evaporation, a less precise precursor to sputter coating.
With the invention of the planar magnetron sputter source in the early 1970s,
multi-layer coatings for large substrates became possible. Magnetron sputtering
has been used in a large number of applications which high quality, uniform
coatings need to be deposited on large surfaces or on many smaller surfaces
simultaneously. Examples of sputter coating are the deposition of various metal
and metal oxide layers on wafers in the semiconductor industry, coatings in the
hard disk industry, and optical coatings on transparent surfaces in the
electronic display, automotive glass, and residential and commercial building
markets.

    Thin-film coatings are used in a wide variety of surface applications to
control the transmission and reflection of light and electromagnetic emissions.
Thin-film coatings can modify the transmission and reflection of both visible
and non-visible light, such as infrared and ultra-violet light, to enhance the
performance and characteristics of the surface.

THIN-FILM PROCESS TECHNOLOGIES

    The three most common methods for commercially producing thin-film coatings
on glass and flexible substrates are:

    - WET COATING. The wet coating process generally involves depositing a thin
      layer of material onto glass by a spin coating technique. In the case of
      spin coating, which is sometimes used for computer display tubes, or CDTs,
      a small amount of liquid is placed at the center of a spinning CDT,
      forcing the liquid from the center towards the outside edge. Once a
      uniform thin-film layer is thus applied, the film is bake-dried at a
      moderate temperature. This technique is typically used for smaller sized
      displays where lower performance characteristics are acceptable. We are
      not aware of the commercially viable use of this process in connection
      with the manufacture of displays larger than 17 inches.

    - DIRECT COATING ONTO GLASS SUBSTRATES. Direct coating onto glass can be
      accomplished by sputtering and by pyrolytic means. Direct-to-glass
      sputtering is a mature, well-known process for applying thin-film coatings
      to glass. Products using this technology to retain heat within a structure
      are common in the building glass market. Pyrolytic coatings are formed
      directly on the glass as it is produced on a float line. The process uses
      the heat of the molten glass to make a single layer, metal oxide coating
      from a solution sprayed onto the glass. Because this technique produces
      only single layer coatings, the solar performance is limited. Glass with
      pyrolytic coatings is only used in residential and commercial buildings
      with less demanding thermal requirements. In addition, the display
      industry employs direct sputtering to coat the face plates of some CDTs.

    - SPUTTER COATING ONTO FLEXIBLE FILM SUBSTRATES. The sputter coating
      process, which is the process we primarily employ, deposits a thin layer
      of materials, generally metals and metal oxides, onto the

                                       26
<PAGE>
      surface of a flexible substrate. The substrate can then be either
      laminated in or applied to glass or suspended between panes of glass.

    The thin-film coating process begins with a clear base substrate which is
typically glass or a flexible polyester film. When using a flexible film, a hard
coat is applied to prevent undesired interactions between the materials to be
deposited and the base substrate. Various materials are then deposited in very
thin layers on the substrate. The process of building up the various layers
results in a "stack." The stack consists of layers of materials that produce the
desired optical and transmission effects. Once the stack is completed, a top
coat is applied to protect the various layers from the outside environment. In
some applications, primarily with flexible films, adhesive or protective layers
may be applied to the back of the substrate.

thin-film coated product.]

OUR MARKETS

    Primary markets for the thin-film coated substrates that we manufacture are
the electronic display, the automotive glass, and the residential and commercial
building glass markets. Advances in manufacturing processes coupled with
improved thin-film deposition technologies in the electronic display and
automotive markets are decreasing production costs, allowing thin-film coated
substrates to more cost-effectively address these markets.

    ELECTRONIC DISPLAYS.  Thin-film coated substrates sold in this market
primarily reduce glare caused by reflection from glass surfaces, improve
contrast and image quality, and reduce electromagnetic emission and build up of
static charge on the computer display screen. Thin-film coated substrates are
used in CRTs, liquid crystal and plasma displays, and in applications such as
touch screens, wireless telephones and automated teller machines. The market for
17 inch and larger flat screen CRTs is anticipated to grow from 4 million units
in 1999 to 32 million units in 2003, according to Stanford

                                       27
<PAGE>
Resources, Inc. Thin-film coated substrates in this market are generally sold to
OEMs, which apply the film to flat screens.

    The use of thin-films in the electronic display market is increasing
primarily due to:

    - growing consumer demand for displayed information, driven largely by the
      availability of information and entertainment on the internet, as well as
      strong growth in the sales of wireless and portable communication devices;

    - growing production of 17 inch and larger flat screens that are ideally
      suited to the application of our films; and

    - the introduction of new products incorporating thin-film technology,
      including active matrix liquid crystal and plasma display screens used in
      industrial and consumer products.

    We began commercial production for the electronic display market in 1996. We
estimate that in 1999, our coated substrates were applied to approximately 33%
of the 17 inch and larger flat screen CRT market, based on information from
Stanford Resources, Inc. and our customers.

    AUTOMOTIVE GLASS.  Thin-film coated substrates sold in this market reflect
infrared heat and reduce ultra-violet light. These coatings allow carmakers to
use more glass and increase energy efficiency by reducing the demand on a
vehicle's air conditioning system, as well as reducing noise levels in vehicles
by up to 50%. Thin-film coated substrates in this market are sold primarily to
original equipment manufacturers for sale to European manufacturers of new cars
for worldwide distribution. These substrates are also sold to original equipment
manufacturers and independent manufacturers as part of a large aftermarket for
retrofit and replacement automobile glass. In addition, thin-film coated
substrates for application to the inside surface of a vehicle window are sold
through resellers who install the film.

    We estimate the average car uses approximately 48 square feet of glass.
Based on such estimate and Standard & Poor's DRI World Car Industry Report
(June 1999), we believe approximately 2.1 billion square feet of glass were
installed in new cars in 1999. Approximately one half of the automotive glass
market uses some form of solar control, a small portion of which currently uses
our product. In addition, we believe the annual retro-fit market for replacement
automobile glass is approximately the same size as the annual market for glass
manufactured for new automobiles.

    The growth in the use of thin-films in the automotive glass market is being
driven primarily by:

    - newly-developed thin-film technologies and production processes, which
      permit the production of less expensive products that are more attractive
      to automobile manufacturers;

    - growing demand for thin-film coated substrates in glass for the automobile
      glass retrofit market, which constitutes approximately one-half of the
      overall annual automotive glass market according to Standard & Poor's DRI
      World Car Industry Report (June 1999); and

    - rising gasoline prices combined with consumer demand for comfort, which
      have created a need for thin-film coatings to provide solar control,
      improve the efficiency of air conditioning and increase gas mileage.

    We began volume production for this market in 1996, and we estimate that in
1999, approximately 6% of the glass used for new luxury automobiles manufactured
in Europe contained our product.

    RESIDENTIAL AND COMMERCIAL BUILDINGS.  Thin-film coated substrates sold into
this market are primarily used to control the transmission of heat through
window glass, as well as to limit ultra-violet light damage. Glass is a
particularly poor thermal barrier. The primary source of heat build-up and loss
in buildings is through the glass windows.

                                       28
<PAGE>
    According to The Freedonia Group, the market for new and replacement glass
sold for use in residential buildings is expected to increase from approximately
2.1 billion square feet in 1998 to approximately 2.7 billion square feet in
2008. According to the Freedonia Group, the market for new and replacement glass
sold for use in commercial buildings is expected to increase from approximately
680 million square feet in 1998 to approximately 1.3 billion square feet in
2008.

    The use of thin-films in the commercial and residential building glass
market is characterized by modest growth driven by:

    - increasing energy conservation concerns;

    - increasing amounts of new and replacement glass sold for use in
      residential buildings; and

    - increasing amounts of new and replacement glass sold for use in commercial
      buildings.

    Our original business, in which we began volume production in 1979, focused
on this market. In 1999, we estimate that our products were used in less than 2%
of the replacement glass used in residential and commercial buildings.

MARKET TRENDS

    The needs of our customers and end-users are driving the evolution of the
thin-film coating industry. Manufacturers in the electronic display, automotive
and building glass markets are increasingly interested in the uses of thin-film
coated substrates as a way to lower investment in tooling and increase
production yields.

    Significant trends in the electronic display market include:

    - GROWING DEMAND FOR FLAT SURFACE TUBES. Flat surface monitors and TVs,
      which offer wider viewing areas and improved viewing images, are becoming
      more popular. Thin-film coated substrates, which cannot be applied to CRTs
      with spherically curved surfaces, can be readily used to improve the
      performance of products with flat surfaces.

    - INCREASING DISPLAY SIZE. As the cost of larger display screens decrease,
      consumers can better afford and often prefer larger screens for improved
      viewing of higher resolution images. Larger display screens require the
      use of more film. Popular screen sizes are increasing from 15, to 17 and
      19 inches. From 1999 to 2003, the compound annual growth rate for flat
      screen 17 inch and larger displays is forecast to be 73.9%, according to
      Stanford Resources, Inc.

    - COMMERCIALIZATION OF FLAT PANEL TECHNOLOGIES. The adoption of advanced
      display technologies such as liquid crystal and plasma displays, which
      require thin-film coated substrates.

    - PREFERENCE FOR HIGHER RESOLUTION DISPLAYS. An increasing portion of the
      electronic products industry is moving to higher resolution displays,
      which are enhanced by advanced thin-film technologies.

    - REDUCTION OF HARMFUL OR UNDESIRABLE EMISSIONS. Electronic product
      manufacturers are seeking ways to mitigate electromagnetic and infrared
      interference, driving the need for coatings that can reduce undesirable or
      potentially harmful radiation emissions by reflecting them back into the
      display without affecting functionality of the display.

    Significant trends in the automotive glass market include:

    - ADVANCED AUTOMOTIVE DESIGNS. New automotive glass designs, such as larger
      and more steeply sloped windows, have resulted in increased heat build-up
      and ultraviolet damage in automobiles, which can be reduced by thin-film
      coatings.

    - ENHANCED FUNCTIONALITY. Automobile manufacturers are looking for ways in
      which thin-film coatings can support new windshield features such as
      electrical defrost and antenna functions,

                                       29
<PAGE>
      including receipt of radio, GPS satellite signals and wireless
      communications. We believe automotive glass with these capabilities will
      be commercially available within three to five years.

    Trends in the residential and commercial building markets include:

    - ENHANCED EFFICIENCY. Demand for heating and cooling efficiency have driven
      the need for thin-film coatings that provide energy savings. These
      concerns include controlling solar radiation, improving the efficiency of
      air conditioning, and offering insulating properties that reduce heat loss
      in cold climates and heat gain in hot climates while reducing ultra-violet
      damage.

    - GROWTH OF REMODELING MARKET. Remodeling of existing structures has
      increased the use of more modern materials, including the use of glass
      that increases thermal and UV protection and provides insulation from
      noise.

STRATEGY

    Our strategy is to enhance our position as a leading developer, manufacturer
and marketer of thin-film coatings on flexible substrates for the electronic
display, automotive glass, and residential and commercial building glass
markets. The following are key elements of our strategy:

EXPAND PRODUCTION CAPACITY TO MEET CURRENT DEMAND IN THE ELECTRONIC DISPLAY AND
  AUTOMOTIVE MARKETS

    We are expanding our electronic display production capacity in our Tempe
manufacturing facility. The latest production machine (PM 6) began to
commercially produce limited amounts of film in the first quarter of 2000. An
additional machine (PM 7) is scheduled for delivery in the second quarter of
2000 and is expected to commence commercial production in the first half of
2001.

    In addition, we intend to expand our production capacity through the opening
of our new manufacturing facility in Dresden. We expect the first production
machine in Dresden (PM 8) will commence commercial production in the second half
of 2000 and the second (PM 9) will commence commercial production by the first
half of 2001. These production machines will primarily produce films for the
European automotive market. We are currently evaluating the need for another
production machine (PM 10) in Dresden.

CAPITALIZE ON EXPANDING FLAT SCREEN DISPLAY MARKET

    We will endeavor to maintain a leading position in the production of
thin-film coated substrates for the flat screen display market, which we expect
will grow substantially over the next five years. We intend to increase our
share of this market by:

    - working closely with dominant players in the sector to successfully
      integrate our solutions into their products;

    - dedicating the financing necessary to meet expanding capacity demand;

    - continuing to explore technology-driven advantages; and

    - diligently pursuing cost reduction in material costs and manufacturing
      programs.

    We seek to acquire a leading share of the rapidly growing LCD market by
establishing relationships with LCD manufacturers to provide thin-film coatings
for more of their products. Further, we will devote resources towards the
development of additional coatings and processes to address the broader LCD
market. These include developing processes to apply our coatings to other
materials used in LCDs, such as tetra acetate cellulose, or TAC.

INCREASE AUTOMOTIVE MARKET PENETRATION AND EXPAND CUSTOMER BASE

    Vehicles using our sputtered thin-film coated products include models by
European automakers Audi, BMW, Mercedes, Volvo, Peugeot-Citroen and Renault. Our
thin-film coated products are sold to these car makers through the two largest
automotive glass laminators operating in Europe, Sekurit St. Gobain and
Pilkington PLC. Our strategy is to use these relationships to increase the use
of our thin-film coated products by customers of these two laminators in other
geographic markets. In addition, we intend to target other major OEMs in the
automotive glass industry in Japan, North America and South America to similarly
integrate our products into their glass components. We believe this laminating
process is easily transferable to most automotive glass lines.

DEVELOP NEW APPLICATIONS FOR THE AUTOMOTIVE GLASS MARKET

    We are using our thin-film expertise to develop new products for the
automotive glass market. For example, we are working with Visteon Corporation,
the largest supplier of automotive glass in the United States, to develop a
heatable automobile windshield using our XIR film as the electrically conductive
medium in the laminated windshield. When development work is complete, the new
product will be capable of de-icing, defrosting and demisting the windshield,
thus improving cold start visibility and reducing the need to scrape ice from
the windshield. In addition, we are working with MegaWave Corporation to build a
prototype antenna for automobile windshields using our XIR film technology. When
completed, the new product would serve as an invisible windshield antenna that
could be used to receive and transmit radio, GPS and wireless communications
signals.

INTEGRATE NEW PRODUCTION TECHNOLOGY

    We are commercializing a deposition technique for our optical coatings
called plasma enhanced chemical vapor deposition, or PECVD. This is commonly
used in the semiconductor and disk drive industries for deposition of active,
interconnected elements or magnetic materials in which high-quality, relatively
thick coatings need to be deposited. The attractiveness of this technique is its
very high deposition rate and the much lower material cost for the coatings, as
compared to sputtering.

    A production machine (PM 7) based on this technology scheduled to be
delivered in the second half of 2000 will be our first system that employs
PECVD. This machine is scheduled to be assembled and tested this year, with
commercial production expected to begin in the first half of 2001. In the
initial phase, the system will be used for the deposition of the silicon dioxide
layer in our electronic display products. Other coatings, both for the
electronic display product line as well as the automotive and residential and
commercial building product lines, may be produced by PECVD in the future.

TECHNOLOGY

    In a sputtering process, a solid target (which provides the coating
material) and a substrate are placed in a vacuum chamber. By adding a small
amount of process gas, typically argon, to the chamber and negatively charging
the target, the process gas is ionized and a plasma discharge is formed. The
positively charged gas ions strike the solid target with enough force to eject
atoms from its surface. The ejected target atoms condense on the substrate and a
thin-film coating is constructed atom by atom. By placing a magnet behind the
target, the electrons in the ionized plasma are confined to a specific region on
the target enhancing the creation of ionized gas atoms and increasing the
efficiency of the target atom ejection process. By using different targets as
the substrate moves through the vacuum chamber, we can create a multi-layered
coating, or stack.

    If the process gas is inert, such as argon, the coating will have the same
composition as the target material. As an example, many of our coatings have a
layer of silver in the stack. However, by adding a reactive gas such as oxygen
or nitrogen to the process, it is possible to create metal oxide or metal

                                       31
<PAGE>
nitride coatings from a metal target. Our XIR coatings are multiple layered
coatings consisting of alternating layers of silver and indium oxide.

    The advantages of our sputtering process include the high density of the
formed coatings and the high degree of uniformity control that we can achieve.

    While predominantly relying on sputter coating technology, we are actively
developing new technologies and processes such as PECVD. The PECVD technique
uses a gas rather than a solid target as the base material for the coating. The
gas in the deposition chamber is excited into a very reactive plasma, using the
energy from a microwave source mounted onto the chamber. A chemical reaction
involving the excitement of gas molecules at the surface of the substrate then
creates the thin-film coating. In the past, this technique lacked the uniformity
control necessary to make it useful for optical coatings, where uniformities of
a few percent are required. New developments in this area have improved PECVD
uniformity levels to the point that PECVD can now be explored for optical
coatings. We plan to employ our new PECVD technology in our new production
machine (PM 7) in Tempe. However, since this system embodies a completely new
technology, we expect and have budgeted for, a much slower start-up of this
system compared to our standard sputter coating systems.

    In addition to the vacuum-based deposition techniques described above, we
have developed the ability to deposit wet chemistry based coatings under
atmospheric conditions. In this technique, the active component of the thin-film
is in a solution and is applied to the substrate by rotating cylinder. After
applying the wet film, the substrate is heated, evaporating the solvent and
leaving a thin-film of the active component behind. In Tempe, this technology is
used to apply an anti-smudge coating on top of our sputtered anti-reflective
films. The function of the anti-smudge coating is to make the final product more
resistant to fingerprints and to make it easier to clean. Other coatings can be
applied through this technique as well, and programs are in place to develop
adhesive coatings and other coatings that enhance the mechanical durability of
our products.

    We primarily rely upon trade secrets and know-how to develop and maintain
our competitive position. We have 28 patents and 8 patent applications pending
in the United States that cover materials, processes, products and production
equipment. We also have patents and patent applications pending in other
countries covering the same technology. Expiration dates for our various patents
range from May 2001 to August 2018. We consider our proprietary technology, as
well as its patent protection, to be a significant factor in our business. In
addition, other companies and universities have obtained patents covering film
configurations and processes. We have obtained licenses under some of these
patents and may from time to time require licenses under additional patents.

ELECTRONIC DISPLAYS

    We believe our sputter coated substrates offer a number of advantages over
alternative technologies available in the electronic display market. Our
products offer the high optical quality necessary for higher resolution
displays. Our substrates can be easily cut into different shapes and sizes,
providing increased flexibility for our customers for use in connection with
thinner displays in a variety of sizes. In addition, our products can
effectively reduce undesirable or potentially harmful emissions without
affecting the resolution of the display.

    ANTI-REFLECTIVE FILMS.  Our anti-reflective films minimize reflection of
visible light, and electromagnetic and infrared emissions, while allowing high
picture quality. Our anti-reflective absorbing, or ARA, films are pigmented and
used in flat screen monitors and televisions. Our anti-reflective clear, or ARC,
films are clear and used in LCD screens.

    SILVER REFLECTING FILMS.  Our light-weight silver reflecting film is a
mirror-like product used as a reflector in large screen televisions and in LCD
backlit screens.

    XIR 70/ARC.  Our XIR 70/ARC product is a clear, conductive version of our
ARA film primarily used in plasma display panels.

    TRANSPARENT CONDUCTORS.  Our ALTAIR-M films are used in products such as
touch panels, liquid crystal displays and electroluminescent displays where the
circuit or conductive material must not obscure the screen. ALTAIR films are
also used in electromagnetic interference shielding, infrared rejection and
electrostatic discharge packaging applications.

AUTOMOTIVE GLASS PRODUCTS

    The sputter coating of substrates offers a more uniform coating than the wet
coating process, providing better optical qualities as required by the
automotive glass market. Direct-to-glass sputtering for automotive windshields
is not well developed because of the need to bend the glass before it can be
applied to an automobile. Coating flat glass and then bending it to match
complex automobile designs is difficult due, in part, to the stress on the
thin-film during the bending, heating and cooling process. Some direct-to-glass
sputtering machines are designed to apply materials to glass already bent to the
final shape of the windshield. To be economical, these machines must be used to
sputter mass quantities of one design of windshield. Sputter coated substrates
can also be applied to windshields with different curvatures and incorporated
into any in-line windshield production process.

    INFRARED REFLECTIVE FILMS.  Our XIR coated solar-control film is a
transparent, sputter-coated, polyester film used in laminated glass for
automobiles. The film has a patented, transparent solar-control coating on one
side and a proprietary adhesion-promotion layer on the other.

    APPLIED SOLAR-CONTROL FILMS.  Our Solis/V-KOOL solar-control films for
aftermarket installation for automotive glass utilizes our XIR technology. The
product is applied to existing windows and has a protective hard coat over the
patented, transparent solar-control coating on one side and the adhesion layer
on the other.

RESIDENTIAL AND COMMERCIAL BUILDING PRODUCTS

    Windows containing our Heat Mirror product have two to five times the
insulating capacity of conventional double-pane windows. They also provide high
levels of solar shading while transmitting a high percentage of visible light.
In addition, our products also offer ultraviolet protection and reduce noise and
condensation build-up. Residential and commercial glass manufacturers are
looking for ways to improve insulation without adding numerous panes of glass
that are impractical to lift and can not

                                       34
<PAGE>
be supported by a structure's frame. This drives the need for thin-film inside
the glass that is a high performance insulator at a fraction of the weight of
the glass.

    SUSPENDED HEAT MIRROR FILMS.  Our Heat Mirror films provide a variety of
shading and insulating properties as well as ultraviolet damage protection.
Windows are the primary areas of heat loss in winter and a major source of heat
gain in summer. Heat Mirror films, which are sold in rolls to window
manufacturers, are suspended in the airspace between sealed double-pane
residential and commercial windows. We have developed and patented this
film-mounting technology, which we license to window fabricators. We currently
offer a variety of different Heat Mirror films for residential and commercial
building applications.

    LAMINATED FILMS.  Our thin-film coated flexible substrates are laminated
between panes of glass and perform similarly to our XIR solar control films for
automobiles. This film is currently sold primarily to fabricators of laminated
window glass for large commercial building applications such as airports, office
buildings, and museums.

    APPLIED SOLAR-CONTROL FILMS.  Our XIR coating for building applications is
Solis/V-Kool solar-control films for the building glass aftermarket. This
product is applied to existing windows and has a protective hard coat over the
patented, transparent solar-control coating on one side and an adhesion layer on
the other.

SALES AND MARKETING

    We sell our electronic display and automobile products primarily to OEMs in
North America, Europe, the Middle East and Asia, principally through our own
direct sales force and sales representatives. Mitsui Chemicals and Marubeni
Corporation are our distributors for Heat Mirror and certain of our electronic
products in Japan. Mitsui also has exclusive manufacturing rights for certain of
our electronic products in Japan using our proprietary sputtering technology.
Samsung Corning is our sales representative in South Korea and China.

    We supply our Heat Mirror building products to approximately 60 insulated
glass and window fabricators and distributors worldwide. Our proprietary
mounting technology is licensed to our customers, who must acquire or build
specialized mounting equipment for the manufacture of Heat Mirror-equipped
windows. Our field services organization trains customers in the manufacture of
Heat Mirror-equipped windows. In North America, we also promote our Heat Mirror
product line through approximately 30 regionally based building glass sales
representatives. We plan to open a Japanese sales office within the next
12 months.

    We have manufacturing and distribution agreements with GMX Associates
Pte. Ltd. which grants GMX an exclusive world-wide license to distribute our
after-market applied film for the automotive and the residential and commercial
glass markets. Our agreement, which is scheduled to expire in 2007, requires GMX
to operate a minimum number of retail stores and to purchase an increasing
annual amount of our products.

    International revenues amounted to approximately 65%, 68%, 77% and 84% of
our net revenues during 1997, 1998, 1999 and the three months ended April 2,
2000, respectively. The principal foreign markets for our products in 1999 were
Japan ($13.3 million), France ($9.7 million), German ($6.7 million) and South
Korea ($3.7 million).

CUSTOMERS

    Our customers include many of the world's leading OEMs in the electronic
display and automotive glass markets. We primarily use resellers and a single
distributor, GMX, for our automotive, and residential and commercial building
aftermarket products.

                                       35
<PAGE>
    Our customers in the electronic display market include Mitsubishi Electric
Corporation, Samsung Devices Company and Marubeni Corporation. Our customers in
the automotive glass market include Sekurit St. Gobain and Pilkington PLC, which
sell automobile glass to automobile manufacturers including Mercedes-Benz,
Renault, Audi, BMW, Volvo, Volkswagen and the PSA Group. Our customers in the
residential and commercial building glass market include approximately 35
fabricators of insulated glass units and laminated glass for commercial
applications.

    A small number of customers have accounted for a substantial portion of our
revenues. Our ten largest customers accounted for 64.2%, 74.2%, 69.2% and 79.5%
of our net product sales in 1997, 1998, 1999 and the first quarter of 2000,
respectively. In 1999, three customers, Sekurit St. Gobain, Pilkington and
MELCO, each accounted for more than 10% of our net revenues. The timing and
amount of sales to these customers depends on sales levels and shipping
schedules for the OEM products into which our products are incorporated. We have
no control over the shipping dates or volume of products shipped by our OEM
customers, and we cannot be certain that they will continue to ship products
that incorporate our products at current levels or at all. In addition, we rely
on our OEM customers to timely inform us of opportunities to develop new
products that serve end-user demands.

RESEARCH AND DEVELOPMENT

    Our research and development activities are focused upon the development of
new proprietary products, thin-film materials science, and deposition process
optimization and automation. Our research and development expenditures totaled
$3.1 million, $3.9 million, $5.2 million and $1.5 million, or 6.1%, 7.8%, 8.5%
and 9.4% of total net revenues, during 1997, 1998, 1999 and the first quarter of
2000, respectively.

    Historically, our research and development efforts have been driven by
customer requests for the development of new applications for thin-film coated
substrates. To meet the future needs of our customers, we continually seek to
improve the quality and functionality of our current products and enhance our
core technology. For example, we are working with Visteon Corporation to develop
a heatable automobile windshield using our XIR film capable of de-icing,
defrosting and demisting the windshield, thus improving cold start visibility
and reducing the need to scrape ice from the windshield. In addition, we are
working with MegaWave Corporation to build a prototype antenna for integration
into an automobile windshield which would be capable of receiving and
transmitting radio, GPS and wireless telephone signals. We have recently
invested time and resources in creating a structured process for undertaking all
product development projects, from the research through a process scale-up and
into a production phase.

    We also maintain a dedicated group in our engineering department,
responsible for designing new production equipment and upgrading existing
systems. Although our production systems are built by outside vendors, we work
closely with our vendors on the detailed implementation of the production
machine designs. Our experience with designing production systems is critical
for the proper construction of these machines. Once a new machine is installed
and accepted from our vendor, our Process Development Group is responsible for
starting up the process and transitioning the system into commercial production.

(1)  We sold PM 3 to an unrelated party in 1995.

(2)  PECVD-based production machine.

(3)  We may order, but have not yet committed to buy, this machine.

    We also have two small-scale sputtering machines in Palo Alto which are used
for pre-production qualification and limited production, when they are not used
for their primary research and development function. In Tempe, we also employ a
wet coating and laminating machine, which is used to apply various topcoats and
adhesives, and for lamination of liner films.

    We recently received ISO 9001 certification of our Palo Alto facilities. We
have begun the ISO 9001 certification process for our Tempe facility.

ENVIRONMENTAL MATTERS

    We use hazardous materials in our research and manufacturing operations and
have air and water emissions that require controls. As a result, we are subject
to stringent federal, state and local regulations governing the storage, use and
disposal of wastes. We have implemented a program to monitor our past and
present compliance with environmental laws and regulations. Although we believe
we are currently in material compliance with such laws and regulations, current
or future laws and regulations may require us to make expenditures for
compliance with chemical exposure, waste treatment or disposal regulations.

SOURCES OF SUPPLY

    We manufacture our products using materials procured from third-party
suppliers. We obtain certain of these materials from limited sources. For
example, the substrates we use in the manufacture of the Heat Mirror product is
only currently available from one qualified source, Teijin, holder of
approximately 10.6% of our common stock. The substrates used in the manufacture
of our anti-reflective film are currently available from only two qualified
sources, Teijin and Di Nippon

                                       37
<PAGE>
Printing. In each case, alternative sources of supply are being pursued;
however, it takes approximately 12 to 18 months for us to qualify a new supplier
and we may not be able to successfully develop alternative sources of supply.

    Furthermore, our production machines are large, complex and difficult to
design and assemble. It can take up to a year from the time we order a machine
until it is delivered. Following delivery, it can take us, with the assistance
of the manufacturer, up to six additional months to test and prepare the machine
for commercial production. There are a limited number of companies that are
capable of manufacturing these machines to our specifications. Our inability in
the future to have new production machines manufactured and prepared for
commercial production in a timely manner would have a material adverse effect on
our business.

BACKLOG

    As of December 31, 1999 and June 15, 2000, we had a backlog of orders able
to be shipped over the next 12 months of approximately $27.0 million and $24.4
million, respectively. None of these orders currently outstanding are firm
orders and all are subject to cancellation. For these reasons, these orders may
not be indicative of our future revenues.

COMPETITION

    The thin-film coatings industry and the markets in which our customers
compete experience rapid technological change, especially in the electronic
display market. Adoption by our competitors of new equipment or process
technologies could adversely affect us.

    We have a number of present and potential competitors, many of which have
greater financial resources and greater selling, marketing and technical
resources than we possess. Other U.S. companies serving some of our markets
include Material Sciences Corporation and CP Films, a business unit of
Solutia, Inc. One of the largest U.K. polymer film companies, Courtaulds PLC,
entered the automotive and commercial building product aftermarket in the
mid-1980's by acquiring a U.S. thin-film manufacturers. Many of our current and
expected future customers of our XIR automotive film product, including Sekurit
St. Gobain, Pilkington PLC, PPG Industries, are capable of producing sputtered
coatings on glass that could compete with our sputter coatings on flexible
substrates.

    We believe competition for our residential and commercial building products
comes primarily from other types of films, various chemical coatings and solar
control coatings deposited directly on glass, as well as heat absorbing glass.
We believe we compete principally on the basis of:

    - a tested process of creating superior sputtered thin-film coatings for
      products in several markets;

    - our ability to easily cut our products, providing our customers with
      inventory versatility and higher production yields;

    - our expertise in substrates and coating materials;

    - our access to specialized design and manufacturing technology expertise,
      giving us the ability to customize our products to meet customer
      specifications; and

    - our ability to make continuous process and system improvements resulting
      in cost savings, better yields, and more efficient production.

EMPLOYEES

    As of May 1, 2000, we had 340 full-time employees, of whom 52 were engaged
in engineering, 231 in manufacturing, and 57 in selling, general management,
finance and administration. We are highly

                                       38
<PAGE>
dependent upon the continuing services of certain technical and management
personnel. None of our employees is represented by a labor union. We consider
our employee relations to be good.

PROPERTIES

    Our administrative, marketing, engineering and manufacturing facilities are
located in six buildings totaling approximately 119,000 square feet in Palo
Alto, California, and one building of approximately 55,000 square feet in Tempe,
Arizona. The buildings in Palo Alto are occupied under leases that expire from
2002 to 2005, with options to extend some of these leases for terms expiring
through 2009. The lease for the building in Tempe expires in 2007, with options
to extend through 2017. We took possession of our new 60,000 square foot
building in Dresden in May 2000.

LEGAL PROCEEDINGS

    We have been named a defendant in a lawsuit filed on April 5, 1996 by Four
Seasons in the United States District Court for the Eastern District of New
York. The lawsuit alleges certain unfair competition, tort and contractual
violations by us and seeks relief in an aggregate amount in excess of
$32 million.

    We have also been named a defendant in a lawsuit filed on March 9, 1998 by
Richard McKernan in the Superior Court in the State of California, County of
Santa Clara. The lawsuit alleges certain strict product liability, fraudulent
concealment, negligence and unfair business practice violations by our company.
A third amended complaint was filed on December 7, 1999, limiting the negligence
claim to California class members.

    In addition, we are involved in certain other legal actions arising in the
ordinary course of business. We believe, however, that none of these actions,
either individually or in the aggregate, will have a material adverse effect on
our business or our consolidated financial position or results of operations.

(1)  Option grants were made under our 1997 stock incentive plan. The options
     vest in four equal annual installments, beginning one year after the grant
     date. In the event of certain corporate transactions such as an acquisition
     or sale of our assets, the outstanding options of our named executive
     officers will become immediately exercisable for fully vested shares of
     common stock, unless the options are assumed or substituted with a
     comparable option by the acquiring company or its parent. In any event, the
     human resources committee has the discretion to accelerate the vesting of
     outstanding options upon certain corporate transactions or involuntary
     terminations following a corporate transaction.

(2) All options were granted at an exercise price equal to the fair market value
    of the common stock on the date of grant. The exercise price may be paid in
    cash or cash equivalents, in shares of the common stock valued at fair
    market value on the exercise date or in a same-day sale program with the
    assistance of a designated brokerage firm.

(3) The potential realizable value at assumed 5% and 10% annual rates of
    compounded stock price appreciation in the table above are required by rules
    of the Securities and Exchange Commission and are based on the fair market
    value or deemed fair market value of the common stock used by us for
    accounting purposes, as applicable, and do not represent our estimates or
    projections of our future stock prices. Actual gains, if any, on stock
    option exercises will be dependent on the future performance of our common
    stock.

AGGREGATED OPTION EXERCISES IN LAST FISCAL YEAR AND FISCAL YEAR-END OPTION
VALUES

    The following table sets forth information concerning option exercises and
unexercised stock options for our fiscal year ended December 31, 1999 with
respect to each named executive officer. The value of unexercised in-the-money
options has been calculated by determining the difference between the exercise
price per share payable upon exercise of these options and the fair market value
of our common stock at the end of 1999 ($4.63 per share). The value realized has
been calculated by determining the difference between exercise price per share
paid upon exercise of the options and the fair market value of the shares on the
date of exercise of the options.

1997 STOCK INCENTIVE PLAN AND 1998 STOCK OPTION PLAN FOR EMPLOYEES AND
CONSULTANTS

    Effective May 21, 1997, we adopted the 1997 stock incentive plan and
authorized an aggregate of 400,000 shares of our common stock to be reserved for
issuance under the plan. The share reserve automatically increases at the
beginning of each year by 250,000 shares. As of June 1, 2000, there were
outstanding options to purchase a total of 1,068,780 shares of common stock
under this plan. The 1997 stock incentive plan is administered by the board of
directors. The board of directors has the authority to construe and interpret
this plan and any agreement made under the plan, grant awards and make all other
determinations necessary or advisable for administration of this plan.

    In August 1998, we adopted the 1998 stock option plan for employees and
consultants and authorized an aggregate of 250,000 shares of our common stock to
be reserved for issuance under the plan. The share reserve automatically
increases at the beginning of each year by 150,000 shares. As of June 1, 2000,
there were outstanding options to purchase a total of 376,459 shares of common
stock under this plan. The 1998 stock option plan is administered by the human
resources committee. The human resources committee has the authority to construe
and interpret this plan and any agreement made under the plan, grant awards and
make all other determinations necessary or advisable for the administration of
this plan.

1997 EMPLOYEE STOCK PURCHASE PLAN

    In March 1997, the 1997 employee stock purchase plan was adopted by our
board of directors and stockholders. 100,000 shares of common stock were
reserved for issuance under this plan. The board of directors and stockholders
approved the issuance of an additional 75,000 shares on May 25, 2000.

                           RELATED PARTY TRANSACTIONS

TEIJIN

    On April 9, 1997, we signed a comprehensive set of collaborative agreements
with a major supplier of our raw materials, Teijin Limited. The agreements
provided for, among other things, the purchase by Teijin of 667,000 shares of
our common stock at a price of $7.50 per share; a guarantee by Teijin of a
$10.0 million loan to us; and an agreement to collaborate to achieve closer
marketing and product development ties between the two companies. We pay a loan
guarantee fee to Teijin at the rate of 0.5625% per year on the outstanding
balance of the loan guaranteed by Teijin. We paid a loan guarantee fee of
$57,500 to Teijin during 1999. Teijin also received warrants to purchase an
additional 158,000 shares of our common stock at $9.00 per share, which expired
in May 2000. We intend to repay $5.0 million of the loan guaranteed by Teijin
with the proceeds of this offering. See "Use of Proceeds."

    Pursuant to these agreements, Teijin has nominated a representative to our
board of directors since 1997. Mr. Hideo Nakamori, President and CEO of Metton
America, Inc., a subsidiary of Teijin, was appointed to our board of directors
in May 1999 and served as a member of the board until May 2000. Mr. Tadahiro
Murakami, President of Teijin-Bayer Polytec Ltd., a subsidiary of Teijin, was
appointed to our board of directors in May 2000. Also, subsequent to the
agreements, Teijin has become a customer for certain of our products, and we
have acquired a license from Teijin for rights to manufacture and sell under
certain patents owned by Teijin in Japan. During 1999, we paid Teijin $100,000
for license fees and approximately $10.7 million for purchases of raw material
substrates.

TRANSACTIONS INVOLVING DIRECTORS

    In April, 1997, we entered into a development and technology agreement with
Energy Conversion Devices, Inc., or ECD. The agreement provides that we will
jointly pursue the commercialization of the process of sputter coating on
flexible substrates with ECD. We paid ECD $40,000 under the agreement for
development activities in 1998 and nothing in 1999 or the first quarter of 2000.
The agreement further provides that we will pay ECD a royalty in an amount which
is based upon the volume of product produced through the PECVD process. To date,
the process has not been commercialized and we have not paid ECD any royalties
under the agreement. In February 1999, we contracted with ECD to retrofit a
production machine (PM 7) to incorporate the PECVD process. This machine will be
shipped to Tempe in the second half of 2000. We paid ECD approximately $930,250
in 1999 in connection with its conversion of PM 7 to the use of PECVD
technology. Robert C. Stempel, a director of our Company since May 2000, is the
Chairman of ECD.

    Bruce J. Alexander, one of our directors, is a managing director of
Needham & Company, Inc. the managing underwriter for this offering. In his
capacity as a managing director of Needham & Company, Inc., Mr. Alexander may be
deemed to benefit indirectly from the underwriting commission to be paid by us
to the underwriters in connection with in this offering.

LOANS TO OFFICERS AND DIRECTORS

    During 1999, we lent certain amounts to Bruce J. Alexander ($39,375), Thomas
G. Hood ($25,313), and Catherine B. Poliak ($4,125) to permit them to exercise
Southwall stock options held by each of them. In each case the indebtedness is
represented by a note payable to us due one year after the loan bearing interest
at the rate of 7.0% per annum. Interest is payable at the time the loan is due.
Loans may be extended for one year terms if approved by the board of directors.
In addition, Messrs. Alexander and Hood were indebted to us during 1999 for
additional amounts lent to them prior to 1999 to permit them to exercise
options. Such indebtedness is also represented by notes payable to us which have
been extended to December 31, 2000 bearing interest at the rate of 7.0% per
annum. The largest amount of indebtedness outstanding under such notes at any
time during 1999 was $381,164 in the case of Mr. Alexander, $73,050 in the case
of Mr. Hood and $22,136 in the case of

                                       46
<PAGE>
Ms. Poliak. As of April 17, 2000, the amount of indebtedness under such notes
was $0 in the case of Mr. Alexander, $73,050 in the case of Mr. Hood and $11,836
in the case of Ms. Poliak.

    We believe that all transactions described above were made on terms no less
favorable to us than would have obtained from unaffiliated third parties. All
future transactions, if any, with our executive officers, directors and
affiliates will be on terms no less favorable to us than could be obtained from
unrelated third parties and will be approved by a majority of the board of
directors and by a majority of the disinterested members of the board of
directors.

                          DESCRIPTION OF CAPITAL STOCK

AUTHORIZED AND OUTSTANDING CAPITAL STOCK

    Effective upon the closing of this offering, our authorized capital stock
will consist of 20,000,000 shares of common stock, par value $.001 per share.

    The following summary description of our capital stock, as of the closing of
this offering, is qualified by reference to the provisions of applicable law and
to our Restated Certificate of Incorporation filed as an exhibit to the
registration statement of which this prospectus is a part.

COMMON STOCK

    As of April 2, 2000, there were approximately 7,888,674 shares of our common
stock outstanding and held of record by approximately 296 stockholders. Based
upon the number of shares outstanding as of April 2, 2000 and giving effect to
the issuance of the shares of common stock offered by Southwall hereby, there
will be approximately 10,388,674 shares of common stock outstanding upon the
closing of this offering. In addition, as of June 1, 2000, there were
outstanding stock options to purchase a total of 1,445,329 shares of our common
stock.

ANTI-TAKEOVER EFFECTS OF PROVISIONS OF OUR RESTATED CERTIFICATE OF INCORPORATION
AND BY-LAWS

    Our Restated Certificate of Incorporation and By-Laws and the Delaware
General Corporation Law contain certain provisions that could discourage, delay
or prevent a change in control of Southwall or our acquisition at a price which
many stockholders may find attractive. The existence of these provisions could
limit the price that investors might be willing to pay in the future for shares
of common stock.

CERTIFICATE OF INCORPORATION AND BY-LAWS

    Certain provisions of our corporate charter and by-laws, which will be in
effect after the closing of this offering, might discourage, delay or prevent a
change of control or a change in our management, even if such changes would be
beneficial to our stockholders. The most important provision is the ability of
our board of directors, without stockholder approval, to issue any class or
series of preferred stock with dividend rights, dividend rates, conversion
rights, redemption rights, preferences on liquidation or dissolution, voting
rights and any other preferences, which could adversely affect the voting power
of the holders of common stock. The existence of this provision could limit the
price that investors might be willing to pay in the future for shares of our
common stock and could deprive you of an opportunity to receive a premium for
your common stock as part of a sale.

EFFECT OF DELAWARE ANTI-TAKEOVER STATUTE

    We are subject to Section 203 of the General Corporation Law of Delaware
which, subject to some exceptions, prohibits a publicly held Delaware
corporation from engaging in any business combination with any interested
stockholder for a period of three years following the date that the stockholder
became an interested stockholder.

    Section 203 does not apply if:

    - prior to that date, the board of directors of the corporation approved
      either the business combination or the transaction which resulted in the
      stockholder becoming an interested stockholder;

    - upon consummation of the transaction which 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

                                       50
<PAGE>
      determining the number of shares outstanding those shares owned by persons
      who are directors and also officers and 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

    - 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 two-thirds of the outstanding voting stock which is not owned by the
      interested stockholder.

    The application of Section 203 may limit the ability of stockholders to
approve a transaction that they may deem to be in their best interests.

    Section 203 defines "business combination" to include:

    - any merger or consolidation involving the corporation and the interested
      stockholder;

    - any sale, transfer, pledge or other disposition of 10% or more of the
      assets of the corporation to or with the interested stockholder;

    - subject to some exceptions, any transaction which results in the issuance
      or transfer by the corporation of any stock of the corporation to the
      interested stockholder;

    - any transaction involving the corporation which 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

    - the receipt by the interested stockholder of the benefit of any loans,
      advances, guarantees, pledges or other financial benefits provided by or

    In general, Section 203 defines an "interested stockholder" as any entity or

LIMITATION OF LIABILITY

    Our charter provides that none of our directors shall be personally liable
to us or to our stockholders for monetary damages for breach of fiduciary duty
as a director, except that the limitation shall not eliminate or limit liability
to the extent that the elimination or limitation of the liability is not
permitted by the Delaware General Corporation Law as the same exists or may
hereafter be amended.

    Our by-laws provide for the indemnification of our directors and officers to
the fullest extent permitted by the General Corporation Law of Delaware. A
principal effect of these provisions is to limit or eliminate the potential
liability of our directors for monetary damages arising from breaches of their
duty of care, subject to certain exceptions. These provisions may also shield
directors from liability under federal and state securities laws.

STOCK TRANSFER AGENT

    The transfer agent and registrar for our common stock is Boston EquiServe,
Canton, Massachusetts.

                        SHARES ELIGIBLE FOR FUTURE SALE

    Upon completion of this offering, we will have outstanding 10,388,674 shares
of common stock. Of these shares,       shares (plus any shares issued upon
exercise of the underwriters' over-allotment option) will be freely tradable
without restriction under the Securities Act, unless purchased by "affiliates"
of ours as that term is defined in Rule 144 under the Securities Act. Affiliates
generally include officers, directors or 10% stockholders. Shares eligible to be
sold by affiliates pursuant to Rule 144 are subject to volume restrictions as
described below.

    The remaining       shares outstanding are "restricted securities" within
the meaning of Rule 144 under the Securities Act. These shares may be sold in
the public market only if registered or if they qualify for an exemption from
registration under Rules 144 or 144(k) under the Securities Act, which are
summarized below. Sales of these shares in the public market, or the
availability of the shares for sale, could cause the market price of our common
stock to decline.

    Our officers, directors, and some of our other stockholders have entered
into lock-up agreements generally providing that they will not offer, sell,
contract to sell or grant any option to purchase or otherwise dispose of our
common stock or any securities exercisable for or convertible into our common
stock owned by them (other than the shares they may purchase and sell on the
open market) for a period of 180 days after the effective date of the
registration statement filed pursuant to this offering. As a result of these
contractual restrictions, notwithstanding possible earlier eligibility for sale
under the provisions of Rules 144 and 144(k), shares subject to lock-up
agreements will not be salable until the agreements expire or are waived. Taking
into account the lock-up agreements, the following shares will be eligible for
sale in the public market at the following times:

    - beginning on the effective date, only the shares sold in the offering and
      those already in the public market will be immediately available for sale
      in the public market;

    - beginning 180 days after the effective date, approximately       shares
      will be eligible for sale pursuant to Rules 144 and 144(k), of which all
      but       shares are held by affiliates; and

    - an additional       shares will be eligible for sale pursuant to Rule 144
      on       , 2000.

RULE 144

    Under Rule 144, beginning 180 days after the effective date of the
registration statement of which this prospectus is a part, a person or persons
whose shares are aggregated, who has beneficially owned restricted shares for at
least one year, which includes the holding period of any prior owner other than
an affiliate, would generally be entitled to sell within any three-month period
a number of shares that does not exceed the greater of:

    - 1% of the outstanding shares of our common stock then outstanding, which
      will equal approximately       shares immediately after this offering; or

    - the average weekly trading volume of our common stock on the Nasdaq
      National Market during the four calendar weeks preceding the filing of a
      notice on Form 144 with respect to the sale.

    Sales under Rule 144 are also subject to manner of sale provisions and
notice requirements and to the availability of current public information about
us.

RULE 144(k)

    Under Rule 144(k), a person who was not an affiliate of us at any time
during the 180 days preceding a sale, and who has beneficially owned the shares
proposed to be sold for at least two years, which includes the holding period of
any prior owner except an affiliate, is entitled to sell these shares

                                       52

without complying with the manner for sale, public information, volume
limitation or notice provisions of Rule 144.

    The underwriting agreement provides that the obligations of the several
underwriters to purchase the shares of common stock offered hereby are subject
to certain conditions precedent and that the underwriters will purchase all
shares of the common stock offered hereby, other than those covered by the
over-allotment option described below, if any of these shares are purchased.

    The underwriters propose to offer the shares of common stock to the public
at the public offering price set forth on the cover of this prospectus and to
dealers at a price that represents a concession not in excess of $         per
share under the public offering price. The underwriters may allow, and these
dealers may re-allow, a concession of not more than $      per share to other
dealers. After the public offering, the representative of the underwriters may
change the offering price and other selling terms.

    We have granted to the underwriters an option, exercisable no later than 30
days after the date of this prospectus, to purchase up to 450,000 additional
shares of common stock at the public offering price less the underwriting
discounts and commissions set forth on the cover page of this prospectus. The
underwriters may exercise this option only to cover over-allotments made in
connection with the sale of the common stock offered hereby. To the extent that
the underwriters exercise this option, each of the underwriters will become
obligated, subject to conditions, to purchase approximately the same percentage
of additional shares of common stock as the number of shares of common stock to
be purchased by it in the above table bears to the total number of shares of
common stock offered hereby. We will be obligated, pursuant to the option, to
sell these additional shares of common stock to the underwriters to the extent
the option is exercised. If any additional shares of common stock are purchased,
the underwriters will offer the additional shares on the same terms as those on
which the 3,000,000 shares are being offered.

    The underwriting fee is equal to the public offering price per share of
common stock less the amount paid by the underwriters to us per share of common
stock. The underwriting fee is currently expected to be approximately    % of
the public offering price. We have agreed to pay the

                                       54

underwriters the following compensation, assuming either no exercise or full

    In addition, we estimate that our share of the total expenses of this
offering, excluding underwriting discounts and commissions, will be
approximately $500,000.

    We have agreed to indemnify the underwriters against some specified types of
liabilities, including liabilities under the Securities Act, and to contribute
to payments the underwriters may be required to make in respect of any of these
liabilities.

    Our directors, officers and some of our other stockholders have agreed not
to offer, sell, contract to sell or otherwise dispose of, or enter into any
transaction that is designed to or could be expected to, result in the
disposition of any shares of our common stock or other securities convertible
into or exchangeable or exercisable for shares of our common stock or
derivatives of our common stock owned by these persons prior to this offering or
common stock issuable upon exercise of options or warrants held by these persons
for a period of 180 days after the effective date of the registration statement
of which this prospectus is a part without the prior written consent of
Needham & Company, Inc. This consent may be given any time without public
notice. We have entered into a similar agreement with the representatives of the
underwriters, except that we may grant options and sell shares pursuant to our
1998 stock option plan, the 1997 stock incentive plan or the 1997 employee stock
purchase plans, without its consent.

    Bruce J. Alexander, a member of our Board of Directors since May 1981,
presently serves as a Managing Director of Needham & Company, Inc. From
March 1987 to July 1991, he was President and Chief Executive Officer of
Southwall, and from February 1982 to March 1987, he held various offices with
us, including Executive Vice President, Vice Chairman of the Board, Chairman and
acting Chief Executive Officer, and Chief Financial Officer.

    In order to facilitate the offering of our common stock, the underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
market price of our common stock. Specifically, the underwriters may over-allot
shares of our common stock in connection with this offering, thus creating a
short position in our common stock for their own account. A short position
results when an underwriter sells more shares of common stock than that
underwriter is committed to purchase. Additionally, to cover these
over-allotments or to stabilize the market price of our common stock, the
underwriters may bid for, and purchase, shares of our common stock in the open
market. Finally, Needham & Company, Inc., on behalf of the underwriters, may
also reclaim selling concessions allowed to an underwriter or dealer if the
underwriting syndicate repurchases shares distributed by that underwriter or
dealer. Any of these activities may maintain the market price of our common
stock at a level above that which might otherwise prevail in the open market.
These transactions may be effected on the Nasdaq National Market or otherwise.
The underwriters are not required to engage in these activities and, if
commenced, may end any of these activities at any time.

    In connection with this offering, certain underwriters and selling group
members (if any), or their respective affiliates who are qualifying registered
market makers on the Nasdaq National Market, may engage in passive market making
transactions in our common stock on the Nasdaq National Market in accordance
with Regulation M under the Securities Exchange Act of 1934 during the two
business day

                                       55

period before commencement of offers or sales of the common stock offered by
means of this prospectus. The passive market making transactions must comply
with applicable volume and price limits, and be identified as such. In general,
a passive market maker may display its bid at a price not in excess of the
highest independent bid for the security; if all independent bids are lowered
below the passive market maker's bid, however, such bid must then be lowered
when certain purchase limits are exceeded.

    Our common stock listed on The Nasdaq Stock Market's National Market under
the symbol "SWTX."

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of

Southwall Technologies Inc.

    In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of stockholders' equity and of cash flows
present fairly, in all material respects, the financial position of Southwall
Technologies Inc. (the "Company") and its subsidiaries at December 31, 1999 and
1998, and the results of their operations and their cash flows for each of the
three years in the period ended December 31, 1999 in conformity with accounting
principles generally accepted in the United States. 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 of these statements in accordance with auditing standards
generally accepted in the United States, which 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,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

    The consolidated financial statements include the accounts of Southwall
Technologies, Inc. and its wholly owned subsidiaries. All significant
intercompany balances and transactions have been eliminated on consolidation.

MANAGEMENT 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
disclosures 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.

COMPREHENSIVE INCOME (LOSS)

    The Company has adopted the provisions of Statement of Financial Accounting
Standards No. 130 "Reporting Comprehensive Income," ("SFAS No. 130"). SFAS
No. 130 establishes standards for reporting and display in the financial
statements of total net income and the components of all other non-owner changes
in equity, referred to as comprehensive income (loss). Accordingly, the Company
has reported translation loss from consolidation of its foreign subsidiary in
comprehensive income (loss).

CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS

    Cash equivalents and short-term investments consist of Eurodollar
certificates of deposit, money market and mutual funds. Investments with
maturities of three months or less from the date of purchase are included in
cash equivalents.

    The Company has classified its short-term investments as "available-for-sale
securities". At December 31, 1999, the difference between cost and fair market
value was insignificant and the gains/ losses on sales of securities during the
year were insignificant.

NOTE 1--THE COMPANY AND A SUMMARY OF ITS SIGNIFICANT ACCOUNTING POLICIES:
(CONTINUED)
FAIR VALUE DISCLOSURES OF FINANCIAL INSTRUMENTS

    The Company has estimated the fair value amounts of its financial
instruments using available market information and valuation methodologies
considered to be appropriate and have determined that the book value of the
Company's debt at December 31, 1998 and 1999 approximates fair value.

CONCENTRATION OF CREDIT RISK

    Financial instruments that potentially subject the Company to significant
concentrations of credit risk consist principally of cash equivalents,
short-term investments and trade accounts receivable.

    The Company invests in a variety of financial instruments such as
certificates of deposits and money market funds. The Company, by policy, limits
the amount of credit exposure to any one financial institution or commercial
issuer.

    The Company sells its products throughout the world. The Company performs
ongoing credit evaluations of its customers' financial condition and, generally,
requires no collateral from its customers. The Company maintains an allowance
for uncollectible accounts receivable based upon expected collectibility of all
accounts receivable. The write-off of uncollectible amounts has been
insignificant.

    At December 31, 1998, receivables from two customers represented 25% and 20%
of the Company's accounts receivables, respectively. At December 31, 1999,
receivables from three customers represented 19%, 17% and 12% of the Company's
accounts receivable, respectively.

REVENUE RECOGNITION

    Revenues from product sales are recognized upon product shipment, provided
that no significant obligations remain and collectibility is probable.
Provisions for estimated cost of warranty repairs and returns and allowances are
recorded at the time products are shipped.

    The Company has agreements under which it receives fees for certain rights
to technology and products. License revenues associated with these agreements
are recognized when earned and collected or is certain to a reasonable degree.

RESEARCH AND DEVELOPMENT EXPENSE

    Research and development costs are expensed as incurred in accordance with
Statement of Financial Position Standard No.2, "Accounting for Research and
Development Costs".

INVENTORIES

    Inventories are stated at the lower of cost (determined by the first-in,
first-out method) or market. Cost includes materials, labor and manufacturing
overhead.

NOTE 1--THE COMPANY AND A SUMMARY OF ITS SIGNIFICANT ACCOUNTING POLICIES:
(CONTINUED)
PROPERTY AND EQUIPMENT

    Property and equipment are stated at cost. The Company uses the
units-of-production method for calculating depreciation on certain of its
production machines and the straight-line method for all other property and
equipment. Estimated useful lives of the assets range from five to ten years. On
its large-scale production machines for which the units-of-production
depreciation method is used, the Company records minimum annual depreciation of
at least one-half of the depreciation that would have been recorded utilizing
the straight-line depreciation method over a ten-year life. Leasehold
improvements are amortized using the term of the related lease or the economic
life of the improvements, if shorter.

    Additions, major renewals and betterments are included in the asset accounts
at cost. Ordinary maintenance and repairs are charged to expense as incurred.
Gains or losses from disposal are included in earnings.

IMPAIRMENT OF LONG-LIVED ASSETS

    The Company evaluates the recoverability of its long-lived assets in
accordance with Statement of Financial Accounting Standards ("SFAS")No. 121,
"Accounting for Impairment of Long-Lived Assets and for Long-Lived Assets to be
disposed of." SFAS No. 121 requires recognition of impairment of long-lived
assets in the event the net book value of such assets exceeds the future
undiscounted cash flows attributable to such assets. No such losses have been
recognized through December 31, 1999.

INTANGIBLE ASSETS

    Patents, licenses and trademarks relating to the Company's commercial
products are stated at cost less accumulated amortization. Amortization is
computed on the straight-line basis over terms of up to 17 years. At
December 31, 1997, 1998 and 1999, patents, licenses and trademarks are included
in other assets in the amount of $843, $852 and $723, net of accumulated
amortization of $930, $947 and $1,119, respectively. Amortization expense for
1997, 1998 and 1999 was $113, $176 and $172, respectively.

STOCK-BASED COMPENSATION EXPENSE

    The Company accounts for stock based compensation to employees using the
intrinsic value method in accordance with Accounting Principle Board Opinion
No. 25, ("APB 25"), "Accounting for Stock Issued to Employees", as permitted
under the provisions of Statement of Financial Accounting Standards No. 123,
("SFAS 123"), "Accounting for Stock-Based Compensation". The Company also
provides additional pro forma disclosures as required under SFAS 123.

INCOME TAXES

    The Company accounts for income taxes under the liability method, which
recognizes deferred tax assets and liabilities for the expected tax consequences
of temporary differences between the tax basis of assets and liabilities and
their financial statement reported amount.

NOTE 1--THE COMPANY AND A SUMMARY OF ITS SIGNIFICANT ACCOUNTING POLICIES:
(CONTINUED)
NET INCOME (LOSS) PER SHARE

    Basic net income (loss) per share is computed as net income (loss) available
to common stockholders divided by the weighted-average number of common shares
outstanding. Diluted net income per share is computed as net income available to
common stockholders divided by the weighted-average number of common shares
outstanding and dilutive potential common shares outstanding, including stock
options, restricted stock awards, warrants and other convertible securities.
Diluted net loss per share is computed the same as basic net income (loss) per
share since the inclusion of potential common shares would result in an
anti-dilutive (lower) loss per share amount. All options outstanding during 1998
were excluded from the diluted net loss per share calculations because they were
anti-dilutive in view of the losses incurred by the Company.

    During the years ended December 31, 1997, 1998 and 1999 there were no
differences between the numerators used for the basic and diluted net income
(loss) per share calculations. The total amount of the differences in the
denominator in 1997 and 1999 is attributable to the effect of dilutive common
stock options.

FOREIGN CURRENCY TRANSLATION

    The Company's German subsidiary uses its local currency as its functional
currency. Assets and liabilities are translated at exchange rates in effect at
the balance sheet date and income and expense accounts at average exchange rates
during the year. Resulting translation adjustments are recorded directly to a
separate component of stockholders' equity.

RECENT ACCOUNTING PRONOUNCEMENTS

    In June 1998, the Financial Accounting Standards Board issued SFAS
No. 133,"Accounting for Derivatives and Hedging Activities" ("SFAS 133").
SFAS 133 was effective for all fiscal quarters beginning with the quarter ending
June 30, 1999. SFAS 133 establishes accounting and reporting standards of
derivative instruments, including certain derivative instruments embedded in
other contracts, and for hedging activities. In July 1999, the Financial
Accounting Standards Board issued SFAS No. 137 "Accounting for Derivative
Instruments and Hedging Activities--Deferral of the Effective Date of FASB
Statement No. 133"("SFAS 137") SFAS 137 deferred the effective date until the
first fiscal quarter ending June 30, 2000. The Company has not engaged in
hedging activities or invested in derivative instruments.

    In December 1999, the Securities and Exchange Commission issued SAB
No. 101, "Revenue Recognition in Financial Statements," which provides guidance
on the recognition, presentation, and disclosure of revenue in financial
statements filed with the SEC. SAB No. 101 outlines the basic criteria that must
be met to recognize revenue and provides guidance for disclosures related to
revenue recognition policies. SAB 101 will be effective for fiscal years
beginning after December 15, 1999. The Company believes that adoption of SAB
No. 101 will not have a material impact on its financial position, results of
operations or cash flows.

NOTE 3--BANK LINE OF CREDIT

    The Company has a $7 million receivable financing line of credit ("line of
credit") with a bank. The amount of borrowing is based upon 80% of the approved
accounts receivable balance, and bears a finance fee of 0.088% per month
(approximately 12% per annum) of the average daily account balance outstanding
during the settlement period. In lieu of the line of credit, the Company granted
to the bank a continuing lien upon and security interest in, and right of set

    The promissory note dated December 16, 1996 is payable to a leasing company.
The borrowings are collateralized by certain production equipment, bear interest
at an annual rate of 9.7037% and are subject to certain financial covenants. The
Note is payable in monthly installments plus interest for a term of 48 months.
At December 31, 1999 the Company was not in compliance with certain of the
financial covenants pertaining to this promissory note. The Company has received
a waiver from the leasing company for failure to comply with such covenants
through the remaining term of the loan. The amount is repayable in the next
12 months and has been classified as current.

    The promissory note dated May 6, 1997 is payable to a bank. The note
payments are guaranteed by Teijin Limited of Japan ("Teijin"), a stockholder and
supplier of the Company (See Note 10). The Teijin guarantee is collateralized by
certain equipment located in the Company's Tempe, Arizona manufacturing facility
and inventory to the extent necessary to provide 120% net book value coverage of
the outstanding loan balance. The interest rate on the loan is re-set
semi-annually at LIBOR plus 0.4375%, (6.1313% at December 31, 1999), and the
Company is subject to certain financial covenants. A loan guarantee service fee
is payable to Teijin semi-annually on the outstanding balance at the rate of
0.5625%. The note provides for semi-annual payments of interest only during the
first four years, followed by semi-annual installments plus interest for the
remaining three and one half year term. At December 31, 1998, the Company was
not in compliance with certain of the financial covenants, therefore, the full
principal amount was classified as a current liability. At December 31, 1999 the
Company was not in compliance with certain of the financial covenants pertaining
to this promissory note, however, the Company has received a waiver from Teijin
through December 31, 1999. During 1999 the Company negotiated new financial
covenants for the years 2000 and 2001. The long-term principal amount at
December 31, 1999 has been classified according to the terms of this agreement.

    During 1999, the Company entered into two equipment sale-leaseback
agreements with a leasing company ("Lessor"). Because the Company has an option
to purchase the equipment at a price to be determined between the Company and
the Lessor at the end of the lease period, the sale-leaseback

NOTE 4--LONG-TERM DEBT (CONTINUED)
agreements have been treated as financing. One lease agreement has a lease term
of three years and the other lease agreement has an initial lease term of two
years with an option to extend it an additional year. At December 31, 1999, the
Company had a total of $6,590 outstanding and due under the leases. The leases
are collateralized by the leased equipment and certain other production
equipment of the Company. The effective interest rate of both leases is
approximately 13% per annum and they are repayable over their term commencing in
May 2000. Additionally, the Company has provided the Lessor an irrevocable
standby letter of credit in the amount of $500 to collateralize all of the
Company's obligations under these agreements. The letter of credit shall not
expire before January 1, 2002. In addition, $1 million of the amount received
from the Lessor is in an escrow account and will be released to the Company
pending the Company meeting certain financial conditions at December 31, 1999.
Due to the uncertainty of compliance with these financial conditions, the
Company has classified this amount under "Other Assets."

    On May 28, 1999, the Company entered into a loan agreement with a German
bank that provides for borrowings up to $6.4 million (DM 12.5 million). Under
the terms of this agreement, the funds will be used solely for capital
investment by the German subsidiary. The term of the loan is for 20 years and
the principle is repayable after the end of 10 years in 20 equal semi-annual
payments. The loan bears interest at 7.10% per annum for the first ten years,
and will be revised to the prevailing rate at the end of the tenth year.

    On August 14, 1999, the Company entered into a loan agreement with a German
bank that provides for borrowings up to $1.7 million (DM 3.3 million). Under the
terms of this agreement, the funds will be used solely for capital investment by
the German subsidiary. The principle balance is due in a single installment on
June 30, 2009 and bears interest at a rate of 5.75% per annum. The interest is
payable quarterly. 50% of the loan is restricted in an escrow account for the
duration of the loan period and was, therefore, classified as a non-current
"Other Asset."

    Other long-term debt consists of capitalized leases related primarily to
certain computer equipment used by the Company.

    In June 1999, the Company repaid a $2,650 convertible debenture to a related
party. Interest paid on the debenture during 1999 was $93.

    Principal reductions of long-term debt are scheduled as follows:

NOTE 4--LONG-TERM DEBT (CONTINUED)
    The Company incurred total interest expense of $892, $1,162 and $1,408 in
1997, 1998 and 1999, respectively. Of these amounts, the Company capitalized
$464 in 1997, $0 in 1998 and $1,115 in 1997, 1998 and 1999, respectively, as
part of the costs related to the construction of certain production machines,
equipment and facilities.

NOTE 5--GOVERNMENT GRANT

    In May 1999, the Company received the approval to receive a grant award (the
"Grant") from the State Government of Saxony in Germany (the "Grantor") for a
maximum amount of approximately $9,467 (DM 18,472).

    The awarding of the Grant is subject to the following requirements:

a)  The grant is earmarked to co-finance the costs of the construction of a
    facility to manufacture Heat Mirror XIR film for the automotive glass
    industry, located at Grossroehrsdorf, Germany.

b)  The construction period for the project is from March 15, 1999 to March 14,
    2002.

c)  The total investment should be at least $37.6 million (DM 73,296).

d)  The project must create at least 143 permanent jobs and 7 apprenticeships.

    In the event that the Company fails to meet the above requirements, the
Grantor has the right to reclaim the Grant.

    During the year ended December 31, 1999, the Company received approximately
$4.9 million (DM 9,600) under this Grant. The Company is scheduled to receive
the remaining balance in 2002.

NOTE 6--INCOME TAXES

    The income tax provision in 1997 resulted primarily from minimum tax
liabilities related to federal taxes and foreign withholding taxes on royalty
payments. The income tax provision in 1999 and 1998 relates primarily to foreign
withholding taxes on royalty payments. The effective income tax rate differs
from the federal statutory rate primarily as a result of the utilization of net
operating loss carryforwards in 1997 and 1999 and the reserves established for
deferred tax assets in 1998. The deferred tax assets valuation allowance at
December 31, 1997, 1998, and 1999 is attributable to federal and state deferred
tax assets. Management believes that sufficient uncertainty exists with regard
to the realizability of these tax assets such that a full valuation allowance is
necessary. These factors include the lack of a significant history of consistent
profits and the lack of carryback capacity to realize these assets. Based on
this absence of objective evidence management is unable to assert that it is
more likely than not that the Company will generate sufficient taxable income to
realize the Company's deferred tax assets.

</TABLE>

    At December 31, 1999 the Company had net federal operating loss
carryforwards of approximately $23.5 million that expire at various dates from
2000 through 2019. The net operating loss carryforwards include approximately
$3.5 million resulting from employee exercises of non-incentive stock options or
disqualifying dispositions, the tax benefit of which, when realized, will be
accounted for as an addition to capital in excess of par value, rather than as a
reduction of the provision for income taxes. Research and development,
investment tax and foreign tax credit carryovers of approximately $0.3 million
are also available to reduce future federal and state income taxes and expire at
various dates through 2004. If certain substantial changes in the Company's
ownership occur, there would be an annual limitation on the amount of the
carryforwards that can be utilized.

NOTE 7--BENEFIT PLANS

STOCK OPTION PLANS

    The Company has granted stock options under various option plans and
agreements in the past and currently under the 1997 Stock Incentive Plan and the
1998 Stock Option Plan for Employees and Consultants. The 1998 Stock Option Plan
for Employees and Consultants was adopted by the Board of Directors on
August 6, 1998. The plans and agreements are administered by the Board of
Directors. The exercise price of options granted under the 1997 and 1998 plans
must be at least 85% of the fair market value of the stock at the date of grant.
All options granted to date under these two plans have been at the fair market
value of the Company's stock on the date of the grant.

    Options under the plans generally vest at a rate of 25% per year, are
non-transferable and generally expire over terms not exceeding ten years from
the date of grant or three months after the optionee terminates their
relationship with the Company.

    During 1997, 1998 and 1999, certain employees, officers and directors of the
Company exercised stock options under the plans by issuing full recourse notes
to the Company with an annual rate of interest of generally 7%. During 1997,
1998 and 1999 outstanding notes to certain of those employees, officers and
directors were extended from terms of one year to terms of two years. Both the
principal and the interest accrued on the notes are due at the end of the term
of each note. These notes aggregate $656, $1,020 and $906 at December 31, 1997,
1998 and 1999, respectively.

EMPLOYEE STOCK PURCHASE PLAN

    In April 1988, the Company adopted the Employee Stock Purchase Plan ("the
Purchase Plan") and reserved 150 shares of Common Stock for issuance thereunder.
In March 1997, the Company adopted the 1997 Employee Stock Purchase Plan ("the
1997 Plan") and reserved 100 shares of Common Stock for issuance thereunder.
Employees of the Company, subject to certain limitations, may purchase shares at
85% of the lower of the fair market value of the Common Stock at the beginning
of the six-month offering period, or the last day of the purchase period. During
1997, 1998 and 1999, 33, 32 and 36 shares, respectively, were sold under the
Purchase Plan and the 1997 Plan. At December 31, 1999 there were no shares
remaining available for issuance under the 1988 Purchase Plan and 11 shares
available for issuance under the 1997 Plan.

ACCOUNTING FOR STOCK-BASED COMPENSATION

    The Company has stock option plans which reserve shares of Common Stock for
issuance to employees, officers, directors and consultants. The Company applies
APB Opinion 25 and related Interpretations in accounting for its plans.
Accordingly, no compensation cost has been recognized for the stock option
plans, except for $123 related to certain transactions in 1996. The Company has
adopted the disclosure-only provisions of SFAS No. 123, Accounting for
Stock-Based Compensation. Had compensation cost for the Company's stock option
plans and stock purchase plans been determined based on the fair value at the
grant date for awards granted in 1997, 1998 and 1999 under

    For the stock option plans, the fair value of each option grant is estimated
on the date of grant using the Black-Scholes option-pricing model for the
multiple option approach with the following weighted average assumptions used
for grants in 1997, 1998 and 1999, respectively. Expected volatility of 60% in
1997, 58% in 1998 and 110% in 1999; risk-free interest rate of 6.4%, 4.5% and
5.4%; and expected lives from vesting date of 0.54, 1.11 and 3.23 years. The
Company has not paid dividends and assumed no dividend yield. The weighted
average fair value of stock options granted in 1997, 1998 and 1999 was $6.86,
$2.51 and $2.60 per share, respectively.

    For the employee stock purchase plans, the fair value of each purchase right
is estimated at the beginning of the offering period using the Black-Scholes
option-pricing model with the following weighted-average assumptions used in
1997, 1998 and 1999, respectively. Expected volatility of 60%, 68%, and 139%;
risk-free interest rate of 5.5%, 5.0% and 5.8%; and expected lives of 0.5 years
in each year. The Company has not paid dividends and assumed no dividend yield.
The weighted-average fair value of those purchase rights granted in 1997, 1998
and 1999 was $2.16, $2.33 and $1.98 per right, respectively.

NOTE 7--BENEFIT PLANS (CONTINUED)
401(K) PLAN

    In 1998, the Company sponsored a 401(k) defined contribution plan covering
eligible employees who elect to participate. The Company is allowed to make
discretionary profit sharing and 401(k) matching contributions as defined in the
plan and as approved by the Board of Directors. The Company matches 25% of each
eligible participant's 401(k) contribution up to a maximum of 20% of the
participant's compensation, not to exceed one thousand dollars per year. The
Company's actual contribution may be reduced by certain available forfeitures,
if any, during the plan year. No discretionary or profit sharing contributions
were made for the years ending December 31, 1997, 1998 and 1999. 401(k) matching
contributions for the years ended December 31, 1997, 1998 and 1999 were $109,
$139 and $230, respectively. The Company has no intention to terminate the plan.

NOTE 8--SEGMENT REPORTING

    In 1998, the Company adopted Statement of Financial Accounting Standards
No. 131 ("SFAS 131"), "Disclosures about Segments of an Enterprise and Related
Information." SFAS 131 supercedes SFAS 14, "Financial Reporting for Segments of
a Business Enterprise" replacing the "industry segment" approach with the
"management" approach. The management approach designates the internal
organization that is used by management for making operating decisions and
assessing performance as the source of the Company's reportable segments.
SFAS 131 also requires disclosures about products and services, geographic
areas, and major customers. The adoption of SFAS 131 did not affect results of
operations or financial position or the segments reported in 1997. The Company
is organized on the basis of products and services. Each of the Company's
product lines (Electronic Display, Automotive Glass and Building Products) has
been aggregated into one operating segment.

and 1999.

CONTINGENCIES

    The Company has been named a defendant in a purported class action lawsuit.
Plaintiffs contend that heat mirror glass units manufactured throughout the
country are subject to clouding and discoloration. The Company is in the process
of filing demurrers and setting pleadings. In addition, several of the Company's
co-defendants have settled their portions of the case. At this point, the
Company intends to vigorously defend this lawsuit by moving to defeat the class
action certification.

    In 1997, the Company was named a defendant in a lawsuit with a manufacturer
of insulated glass units wherein the plaintiff claimed that the insulated glass
manufactured with the use of coated film manufactured by the Company was subject
to various failures and deficiencies, giving rise to warranty and other consumer
claims. Plaintiff is claiming damages for past replacement cost and future
potential claims. The Company is in the process of negotiating a settlement of
these claims.

    The company has been named a defendant in a lawsuit filed on April 5, 1996
by one of its customers in the United States District Court for the Eastern
District of New York. The lawsuit alleges

NOTE 9--COMMITMENTS AND CONTINGENCIES (CONTINUED)
certain unfair competition, tort and contractual violations by the Company and
seeks relief in an aggregate amount in excess of $32 million. In addition, the
Company is involved in a number of other legal actions arising in the ordinary
course of business.

    The Company believes, that the various asserted claims and litigation in
which it is involved will not materially affect its consolidated financial
position, future operating results or cash flows.

    In 1995 the Company started selling its anti-reflective film under a Supply
Agreement to Sony Corporation of Japan ("Sony"). In the fourth quarter of 1998
the Company experienced some quality problems related to the anti-reflective
film that did not meet Sony's specifications. The Company further did not meet
the minimum shipping requirements stated in the Supply Agreement. As a result,
in the fourth quarter of 1998, the Company recorded a $4.0 million charge to
cover any loss contingency, involving write-off of inventory, sales returns and
any penalties associated with the shipment shortfall. During the second quarter
of 1999, the Company reached a settlement with Sony, wherein Sony agreed to
release the Company from any and all penalties, claims, demands and liabilities
that Sony has or will have against the Company in connection with the shipment
shortfall experienced in 1998. In consideration of Sony's waiver, the Company
agreed to wave its claims for payment of the outstanding accounts receivable
with Sony totaling $2.5 million brought forward from 1998. The amount was
written off against the sales return reserve booked in 1998. As of
September 30, 1998, Southwall terminated all production of anti-reflective film
for Sony, as mutually agreed under an amended Supply Agreement, and there were
no further shipments to Sony.

    The Company has the following transactions with related parties in which the

Form 10-K for the year ended December 31, 1999. The condensed consolidated
balance sheet at December 31, 1999 has been derived from the audited financial
statements as of that date. The results of operations for the interim periods

NOTE 3--LINE OF CREDIT AGREEMENT:

    The Company has an $8.0 million receivable financing line of credit with a
bank. Availability under the line of credit is based on 80% of the approved
accounts receivable balances. The line of credit also bears a finance fee of
0.088% per month (approximately 12% per annum) of the average daily outstanding
account balance during the settlement period. In connection with the line of
credit, the Company has granted the bank, a continuing lien upon and security
interest in, and right of set off with respect to all of the Company's rights,
title and interest in all accounts receivable, inventory, monies, remittances
and fixed assets.

NOTE 4--NET INCOME (LOSS) PER SHARE: (CONTINUED)
income per share is computed as net income available to common stockholders
divided by the weighted-average number of common shares outstanding and dilutive
potential common shares outstanding, including stock options, restricted stock
awards, warrants and other convertible securities. Diluted net loss per share is
computed the same as basic net income (loss) per share since the inclusion of
potential common shares would result in an anti-dilutive (lower) loss per share
amount. For the period ended April 4, 1999, there is no difference in the basic
and dilutive loss per share as the Company is in a net loss position, and there
will not be any potentially dilutive common shares.

    During the period ended April 2, 2000, the total amount of the differences
in the denominator is attributable to the effect of 813,000 outstanding,
non-exercised, dilutive common stock options.

NOTE 5--LONG-TERM DEBT:

    The Company's long-term debt consists of the following at April 2, 2000:

    The promissory note dated December 16, 1996 is payable to a leasing company.
The borrowings are collateralized by certain production equipment, bear interest
at an annual rate of 9.7037% and are subject to certain financial covenants. The
Note is payable in monthly installments plus interest for a term of 48 months.
At April 2, 2000 the Company was not in compliance with certain of the financial
covenants pertaining to this promissory note. The Company has received a waiver
from the leasing company for failure to comply with such covenants through the
remaining term of the loan. The amount outstanding is repayable within the year
and has been classified as current debt.

    The promissory note dated May 6, 1997 is payable to a bank. The note
payments are guaranteed by Teijin Limited in Japan ("Teijin"), a stockholder and
supplier of the Company. The Teijin guarantee is collateralized by certain
equipment located in the Company's Tempe, Arizona manufacturing facility and
inventory, to the extent necessary to provide 120% net book value coverage of
the outstanding loan balance. The interest rate on the loan is re-set
semi-annually at LIBOR plus 0.4375%, (6.1313% at April 2, 2000). The Company is
subject to certain financial covenants. A loan guarantee service fee is payable
to Teijin semi-annually on the outstanding balance at the rate of 0.5625%. The
note provides for semi-annual payments of interest only during the first four
years, followed by semi-annual

installments plus interest for the remaining three and one half year term.
Teijin also received warrants in 1997 to purchase 158,000 shares of the
Company's common stock at $9.00 per share. These warrants expire on May 30,
2000. At April 2, 2000 the Company was not in compliance with certain of the
financial covenants with Teijin, the guarantor, pertaining to this promissory
note. The Company received a waiver from Teijin through June 30, 2001.

    During 1999, the Company entered into two equipment sale-leaseback
agreements with a leasing company ("Lessor"). Because the Company has an option
to purchase the equipment at a price to be determined between the Company and
the Lessor at the end of the lease period, the sale-leaseback agreements have
been treated as financing. One lease agreement has a lease term of three years
and the other lease agreement has an initial lease term of two years with an
option to extend it for an additional year. At April 2, 2000, the Company had a
total of $6,534 outstanding and due under the leases. The leases are
collateralized on the leased equipment and certain other production equipment of
the Company. The effective interest rate of both leases is approximately 13% per
annum and they are repayable over their term commencing in May 2000.
Additionally, the Company has provided the Lessor an irrevocable standby letter
of credit in the amount of $0.5 million to collateralize all of the Company's
obligations under these agreements. The letter of credit shall not expire before
January 1, 2002. In addition, $1 million of the amounts received from the Lessor
is in an escrow account and will be released upon the Company meeting certain
financial conditions. Due to the uncertainty of compliance with these financial
conditions, the Company has classified the amount in escrow under non-current
"Other Assets."

    On May 28, 1999, the Company entered into a loan agreement with a German
bank that provides for borrowings up to $6.4 million (DM 12.5 million). Under
the terms of this agreement, the funds will be used solely for capital
investment by the German subsidiary. The term of the loan is for 20 years and
the principal is repayable after the end of 10 years in 20 equal semi-annual
payments. The loan bears interest at 7.10% per annum for the first ten years,
and will be revised to the prevailing rate at the end of the tenth year. The
loan is repayable in Deutschemarks.

    On May 12, 1999, the Company entered into a loan agreement with a German
bank that provides for borrowings up to $2.9 million (DM 6.0 million). Under the
terms of this agreement, the funds will be used solely for capital investment by
the German subsidiary. The term of the loan is for a period of 10 years and the
principal is repayable after the end of 5 years in 10 equal semi-annual
payments. The loan bears interest at 7.10% per annum for the first five years,
and will be revised to the prevailing rate at the end of the fifth year. The
loan is repayable in Deutschemarks.

    An additional loan for $733 (DM 1.5 million) was received from the German
bank discussed above. This loan is an advance on a government grant to be
received approximately August 2001. The proceeds of the grant are collateral for
the loan and, per legal arrangements, will be paid directly to the bank by the
government. Payments of interest only are due until then at 7.10% per annum.

    The preceding three loans are collateralized by the production equipment,
building and land owned by the German subsidiary.

NOTE 5--LONG-TERM DEBT: (CONTINUED)
    On August 14, 1999, the Company entered into a loan agreement with a German
bank that provides for borrowings up to $1.7 million (DM 3.3 million). Under the
terms of this agreement, the funds will be used solely for capital investment by
the German subsidiary. The principal balance is due in a single payment on
June 30, 2009 and bears interest at a rate of 5.75% per annum. The interest is
payable quarterly. 50% of the loan is restricted in an escrow account for the
duration of the loan period and was, therefore, classified as a non-current
"Other Asset." The loan is repayable in Deutschemarks.

    Other long-term debt consists of capitalized leases related primarily to
certain computer equipment used by the Company.

    Principal reductions of long-term debt are scheduled as follows:

    The Company incurred total interest expense of $1,478 and $287 in the first
quarter of 2000 and 1999 respectively. Of these amounts, the Company capitalized
$1,065 and nil in the first quarter of 2000 and 1999, respectively, as part of
the costs related to the construction of new manufacturing facilities in Tempe.

NOTE 6--CONTINGENCIES:

    The Company has been named a co-defendant in a purported class action
lawsuit. Plaintiffs contend that heat mirror glass units manufactured throughout
the country are subject to clouding and discoloration. The Company is in the
process of filing demurrers and setting pleadings. In addition, several of the
Company's co-defendants have settled their portions of the case. At this point,
the Company intends to vigorously defend this lawsuit by moving to defeat the
class action certification.

    In 1997, the Company was named a defendant in a lawsuit with a manufacturer
of insulated glass units wherein the plaintiff claimed that the insulated glass
manufactured, with the use of coated film, manufactured by the Company was
subject to various failures and deficiencies, giving rise to warranty and other
consumer claims. Plaintiff is claiming damages for past replacement cost and
future potential claims. The Company is in the process of negotiating a
settlement of these claims.

    The Company has been named a defendant in a lawsuit filed on April 5, 1996
by one of its customers in the United States District Court for the Eastern
District of New York. The lawsuit alleges

position, future operating results or cash flows.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    The Delaware General Corporation Law and the company's charter and by-laws
provide for indemnification of the company's directors and officers for
liabilities and expenses that they may incur in their capacities. In general,
directors and officers are indemnified with respect to actions taken in good
faith in a manner reasonably believed to be in, or not opposed to, the best
interests of Southwall and, with respect to any criminal action or proceeding,
actions that the indemnitee had no reasonable cause to believe were unlawful.
Reference is made to Southwall's charter and by-laws filed as Exhibits 3.1 and
3.2 hereto, respectively.

    The underwriting agreement provides that the underwriters are obligated,
under certain circumstances, to indemnify directors, officers and controlling
persons of the company against certain liabilities, including liabilities under
the Securities Act of 1933, as amended (the "Securities Act"). Reference is made
to the form of underwriting agreement filed as Exhibit 1.1 hereto.

    In addition, Southwall has a directors and officers liability insurance
policy.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.

    The following sets forth information with respect to securities sold or
issued which were not registered under the Securities Act. No underwriters were
involved in the following sales of securities. These sales were made in reliance
upon an exemption from the registration provisions of the Securities Act set
forth in Section 4(2) thereof relative to sales by an issuer not involving any
public offering or the rules and regulations thereunder. All of the foregoing
securities are deemed restricted securities for purposes of the Securities Act.

    1.  On April 9, 1997, Southwall signed a comprehensive set of collaborative
       agreements with a major supplier of its raw materials, Teijin Limited.
       The agreements provided for, among other things, the purchase by Teijin
       of 667,000 shares of Southwall's common stock at a price of $7.50 per
       share.

    2.  Also in connection with the agreements, Teijin received warrants to
       purchase an additional 158,000 shares of Southwall's common stock at
       $9.00 per share, exercisable within three years from the date of grant.
       These warrants have expired.

ITEM 17. UNDERTAKINGS.

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described in Item 14 above, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission this indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable. In the event that a
claim for indemnification against these liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by a director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether this
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of the issue.

    The undersigned registrant hereby undertakes (1) to provide to the
underwriters at the closing specified in the underwriting agreement,
certificates in the denominations and registered in the names as required by the
underwriters to permit prompt delivery to each purchaser; (2) that for purposes
of determining any liability under the Securities Act, the information omitted
from the form of prospectus filed as part of this registration statement in
reliance upon Rule 430A and contained in a form of prospectus filed by the
registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act
shall be deemed to be part of this registration statement as of the time it was
declared effective; and (3) that for the purpose of determining any liability
under the Securities Act, each post-effective amendment that contains a form of
prospectus shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of the securities at that time
shall be deemed to be the initial bona fide offering thereof.
