ITEM 1. BUSINESS
 
     Litton Industries, Inc. (hereafter together with its consolidated
subsidiaries referred to as the "Company" or "Litton" unless the context
otherwise indicates) is a high-technology electronics company which provides
advanced electronic, defense, marine and technology-based information systems
and products to military, non-defense governmental, civil and commercial
customers. In addition, the Company is a primary builder of large multimission
surface combatant ships and a provider of overhaul, repair, modernization,
design and engineering services, primarily for the U.S. Navy. Litton is also an
international supplier of connectors, multilayer circuit boards, solder
materials, laser crystals and other electronic components used primarily in the
telecommunications, industrial and computer markets. The Company was founded in
California in 1953 and has evolved into a major international organization with
approximately 34,900 employees at more than 26 divisions and seven countries.
 
     The Company's businesses are reported in four business segments: Advanced
Electronics, Information Systems, Marine Engineering and Production, and
Electronic Components and Materials. Information about the Company's business
segments appears on pages F-20 and F-21 of this Annual Report on Form 10-K. This
information includes sales and service revenues, operating profit and
identifiable assets for each of the three years ended July 31, 1998. Effective
August 1, 1997, Information Systems, previously reported with the Advanced
Electronics segment, has been reported as a separate segment. Accordingly, the
segment information for prior periods presented herein has been restated to
reflect this change.
 
  Advanced Electronics
 
     The Advanced Electronics segment is a major supplier and integrator of
electronic systems and related services to the U.S. and international military
and commercial markets. The principal businesses comprising the Advanced
Electronics segment are navigation, guidance and control systems, marine
electronics and electronic warfare systems. The primary products include
inertial navigation systems, IFF (identification friend or foe) systems, marine
bridge, steering and machinery control systems, displays, computers, laser range
finders and target designators, threat warning and electro-optical systems,
microwave tubes and military air traffic control systems. The Company also
provides and integrates shipboard engineering, information and communications
control systems and avionics systems.
 
     Sales backlog for the Advanced Electronics segment was $1.463 billion and
$1.612 billion at July 31, 1998 and 1997. Of the backlog at July 31, 1998, $303
million is expected to be realized as sales in years after fiscal year 1999 and
$960 million is related to worldwide defense contract backlog.
 
     Approximately 48% of the Advanced Electronics segment's revenues in fiscal
year 1998 were derived from sales to the U.S. Government.
 
  Information Systems
 
     The Information Systems segment is a leading supplier of information
systems, technology and related services to the U.S. Government (for both
defense and non-defense applications), as well as state, local and commercial
customers. In addition to systems integration and networking solutions, this
segment supplies tactical command, control and communication systems to military
customers and provides systems and related services and support to other
non-defense governmental and commercial customers. The acquisition of TASC, Inc.
("TASC") in April 1998 provides access to the national intelligence sector and
enhanced the Company's opportunities in the expanding C(4)ISR markets (command,
control, communications, computer, intelligence, surveillance and
reconnaissance).
 
     Firm backlog for the Information Systems segment was $877.7 million and
$518.1 million at July 31, 1998 and 1997. Of the backlog at July 31, 1998, $299
million is expected to be realized as sales in years after fiscal year 1999 and
$434 million is related to defense contract backlog. In addition, PRC Inc.
("PRC", a
 
                                        1
<PAGE>   4
 
subsidiary of the Company) and TASC had unfunded backlog with potential future
contract values totaling approximately $1.8 billion at July 31, 1998 compared
with $1.5 billion for PRC at July 31, 1997.
 
     Approximately 86% of the revenues for the Information Systems segment in
fiscal year 1998 were derived from sales to the U.S. Government.
 
  Marine Engineering and Production
 
     The Marine Engineering and Production segment is engaged in the building of
large multimission surface combatant ships and is a provider of overhaul,
repair, modernization, ship design and engineering services primarily for the
U.S. Navy. Since 1975, the Company has delivered a total of 76 new destroyers,
cruisers and amphibious assault ships to the U.S. Navy. The Company is also
exploring opportunities in commercial vessels, offshore drilling rigs and
production platforms and has been under contract to build multiple offshore
supply vessels for a company engaged in marine supply services.
 
     Sales backlog for the Marine Engineering and Production segment was $3.472
billion and $3.231 billion at July 31, 1998 and 1997, respectively. Of the
backlog at July 31, 1998, approximately $2.407 billion is expected to be
realized as sales in years after fiscal 1999.
 
     Approximately 97% of the revenues for the Marine Engineering and Production
segment in fiscal year 1998 were derived from sales to the U.S. Government.
 
  Electronic Components and Materials
 
     The Electronic Components and Materials segment designs and manufactures
backpanel assemblies, printed circuit boards, specialty motors, slip rings and
signal, power and fiber optic connectors and produces soldering materials, laser
crystals, gallium arsenide substrates and microwave components for primarily
commercial markets worldwide.
 
     Sales backlog for the Electronic Components and Materials segment was
$228.7 million and $164.6 million at July 31, 1998 and 1997, respectively.
Substantially all of the backlog at July 31, 1998 is expected to be realized in
sales in the next fiscal year.
 
  Methods of Distribution
 
     The Company principally markets its products and services throughout the
world through the home offices and branch offices of its various operations. In
general, each of the Company's operations is responsible for selecting,
implementing and maintaining an efficient and effective marketing program.
 
  Raw Materials
 
     The Company uses a wide variety of raw materials in the manufacture of its
many products. The availability of any individual raw material is not critical
to the Company's operations.
 
  Patents
 
     The Company owns a large number of patents, trademarks and copyrights
relating to its manufactured products, which have been obtained over a period of
years. The Company considers these patents, trademarks and copyrights, in the
aggregate, to be valuable to its operations. However, the Company does not
believe that the conduct of its businesses, as a whole, is materially dependent
upon any single patent, trademark or copyright.
 
  Competition
 
     Competition exists with respect to all products manufactured and services
rendered by the Company, particularly with respect to the defense related
businesses. Competition ranges from companies which produce a single product or
offer a single service to some of the world's largest corporations. The Company
is continuing to enhance its competitive position by developing new applications
for its technologies as well as
                                        2
<PAGE>   5
 
pursuing commercial opportunities and developing strategic alliances.
Additionally, recent acquisitions have provided the Company access to
non-defense markets, including the systems integration market, that offer growth
opportunities.
 
  U.S. Government Contracts
 
     Approximately 66% of the Company's total sales and service revenues for
fiscal year 1998 were from U.S. Government contracts and subcontracts.
Approximately 70% of these revenues related to fixed-price type contracts. As is
common with U.S. Government contracts, the Company's U.S. defense contracts are
unilaterally terminable at the option of the U.S. Government with compensation
for work completed and costs incurred. Contracts with the U.S. Government are
subject to certain laws and regulations, the noncompliance with which may result
in various sanctions. In the current government contracting environment,
contractors, sometimes without their knowledge, are subject to investigations by
the U.S. Government initiated in various ways. Most investigations result in no
action being taken or administrative resolution. Litton is aware of ongoing
investigations and is cooperating in those investigations. Should any
investigation result in the filing of formal charges against the Company by the
U.S. Government, disclosure will be made if the amount involved or the relief
sought is deemed by the Company to be material.
 
  Research and Development
 
     Worldwide expenditures on research and development activities amounted to
$233.8 million, $241.8 million and $217.0 million, of which approximately 33%,
29% and 30% was Company-sponsored in the years ended July 31, 1998, 1997 and
1996, respectively. In fiscal 1998, the Advanced Electronics segment accounted
for 61%, of the total research and development expenditures.
 
  Environmental Protection
 
     During the fiscal year ended July 31, 1998, the amounts incurred to comply
with federal, state and local regulations pertaining to environmental standards
did not have a material effect upon the capital expenditures or earnings of the
Company. For additional information with respect to environmental matters, see
Items 3, 7, and 8 of this Annual Report on Form 10-K.
 
  Number of Employees
 
     At July 31, 1998, the Company had approximately 34,900 full-time employees.
Employment by business segment was as follows:

ITEM 3. LEGAL PROCEEDINGS
 
     (a) Litton is suing Honeywell, Inc. ("Honeywell") for patent infringement
relating to the manufacture of ring laser gyro navigation systems which are used
in commercial aircraft. After trial of that case in the U.S. District Court for
the Central District of California, on August 31, 1993, the jury rendered a
verdict in favor of Litton in the amount of $1.2 billion. On January 9, 1995,
the District Court released a Memorandum of Decision finding Litton's patent
invalid and rejecting the jury verdict. Litton appealed to the U.S. Court of
Appeals for the Federal Circuit. On July 3, 1996, the Court of Appeals rendered
a decision reversing the District Court's decision, finding the patent valid and
infringed by Honeywell. The Court of Appeals reinstated the jury's verdict on
liability including the findings of interference with contract and prospective
business advantage and ordered a new trial on the amount of damages sustained by
Litton in the District Court. On March 17, 1997, the U.S. Supreme Court vacated
the Court of Appeals ruling and remanded the case to the Court of Appeals for
further consideration in view of the Supreme Court's decision in Warner-Jenkins
Co. v. Hilton Davis Chemical Co. On April 7, 1998, the Court of Appeals
reinstated its finding that the patent was
 
                                        4
<PAGE>   7
 
valid and ordered a new trial on both liability and damages for the patent and
interference with contract and prospective business advantage claims. The
Company has requested a trial date in December of 1998.
 
     Litton is also suing Honeywell on antitrust grounds in the same U.S.
District Court. On February 29, 1996, a jury rendered a verdict in favor of
Litton. On July 25, 1996, the District Court upheld the jury's verdict that
Honeywell attempted to illegally monopolize and did monopolize the market for
inertial reference systems for large commercial air transport, commuter and
business aircraft. However, the District Court declined to enter the $234
million jury verdict on the basis that Litton's damage study as presented failed
to disaggregate damages between illegal and legal acts. A new trial limited to
the issue of the amount of damages sustained by Litton attributable to
Honeywell's unlawful conduct has been ordered by the District Court. The
District Court set a trial date of October 28, 1998.
 
     (b) The Company and certain of its divisions or subsidiaries have been
named as potentially responsible parties by the United States Environmental
Protection Agency, various state environmental agencies, and other potentially
responsible parties for costs associated with cleanup of a number of sites to
which they may have contributed wastes. Also, the Company and certain of its
divisions and subsidiaries have incurred costs, which have not had a material
impact on the Company's consolidated financial statements in any one year, for
cleaning up a number of sites, presently or formerly owned or leased by the
Company (or by subsidiaries or divisions thereof). In addition, the Company and
certain of its divisions or subsidiaries have been named as defendants in
certain lawsuits for personal injuries and property damage allegedly resulting
from environmental contamination.
 
     At this time, the Company believes that its ultimate liability for
additional expenditures associated with these matters will not materially
adversely affect its consolidated financial statements.
 
     There are various other litigation proceedings in which the Company is
involved. Although the results of litigation proceedings cannot be predicted
with certainty, it is the opinion of the General Counsel that the ultimate
resolution of these other proceedings will not have a material adverse effect on
the Company's financial statements.

     There were no matters submitted to a vote of security holders, through the
solicitation of proxies or otherwise, during the fourth quarter of the fiscal
year ended July 31, 1998.

ITEM 7. FINANCIAL REVIEW AND ANALYSIS
 
     The Company is a high-technology electronics company which provides
advanced electronic, defense, marine and technology-based information systems
and products to military, non-defense governmental, civil and commercial
customers. In addition, the Company is a primary builder of large multimission
surface combatant ships and a provider of overhaul, repair, modernization,
design and engineering services, primarily for the U.S. Navy. Litton is also an
international supplier of connectors, multilayer circuit boards, solder
materials, laser crystals and other electronic components used primarily in the
telecommunications, industrial and computer markets.
 
     Effective August 1, 1997, the Information Systems businesses have been
reported as a separate segment. Accordingly, the segment information relating to
prior fiscal years discussed herein has been restated to reflect this change.
 
     Segment information can be found on pages F-20 and F-21.
 
  Fiscal Year 1998 Compared To 1997
 
     The Company reported sales and operating profit of $4.40 billion and $410.0
million for fiscal year 1998 compared with $4.18 billion and $369.6 million,
respectively, for fiscal year 1997. Operating margins improved for the Advanced
Electronics, Marine Engineering and Production and Electronic Components and
Materials segments. Net earnings and earnings per share rose 12% to $181.4
million and $3.82, respectively, compared with $162.0 million and $3.40,
respectively, for the prior fiscal year.
 
     The Advanced Electronics segment reported sales and operating profit of
$1.59 billion and $110.6 million for fiscal year 1998 compared with $1.53
billion and $96.5 million, respectively, for the fiscal year 1997. The
improvements in sales and operating profit for the current fiscal year were
primarily attributable to higher volume on programs in the integrated avionics
systems and radar warning systems businesses and the acquisition of Racal Marine
Group("Decca") in February 1997. Operating profit also benefited from reduced
program costs in certain defense electronics programs. Backlog for this segment
at July 31, 1998 was $1.46 billion compared with $1.61 billion at July 31, 1997.
 
     The Information Systems segment reported sales and operating profit of
$1.24 billion and $70.4 million for fiscal year 1998 compared with $1.08 billion
and $74.9 million for fiscal year 1997. The increase in sales was mainly due to
the acquisitions of TASC in April 1998, as described in Note B, and SAI
Technology ("SAIT") in March 1997. TASC provides a broad spectrum of
technology-based information services and products to the national intelligence
sector, the U.S. Department of Defense and to non-defense government and
commercial customers. The increase in sales from these acquisitions was offset
by lower than expected volume under the PRC Inc. subsidiary's Super-Minicomputer
contract with various U.S. Government agencies to provide computer systems
integration and networking solutions. Operating profit was also impacted by an
increasingly competitive federal procurement environment and by investments in
new programs and technology made to address new market opportunities associated
with software used in mobile command and control systems and displays and
computer products. Firm backlog at July 31, 1998 for the Information Systems
segment increased to $877.7 million from $518.1 million at July 31, 1997 due
mainly to the acquisition of TASC. In addition, TASC and PRC have unfunded
backlog with potential contract values of up to $1.8 billion at July 31, 1998
compared with $1.5 billion for PRC at July 31, 1997.
 
     The Marine Engineering and Production segment reported sales and operating
profit of $1.03 billion and $134.4 million for fiscal year 1998 compared with
$1.11 billion and $135.0 million for fiscal year 1997. The decline in sales
reflected contracts completed during fiscal years 1997 and 1998 including an
Aegis destroyer and a LHD class amphibious assault ship delivered in the third
and fourth quarter, respectively, of the current fiscal year. This sales decline
was partially offset by other contracts moving into more advanced stages of
production, including a seventh LHD class amphibious assault ship and three
Aegis destroyers. Operating margins improved as a result of increased earnings
rates on programs maturing in the production process and continued production
efficiencies. Current construction activities include four Aegis destroyers, one
LHD class amphibious assault ship, and multiple offshore supply vessels for a
commercial customer. During fiscal year
 
                                        9
<PAGE>   12
 
1998, the U.S. Navy awarded the Company a contract to build six additional Aegis
destroyers with options for two more. Two of the six Aegis destroyers awarded
have been funded for construction and contributed to an increase in backlog to
$3.48 billion at July 31, 1998 from $3.23 billion at July 31, 1997.
 
     The Electronic Components and Materials segment reported sales and
operating profit of $595.8 million and $98.6 million for the current fiscal year
compared with $508.3 million and $69.7 million for the prior year. These
improvements were driven by continued strong demand for this segment's
commercial electronics products as a result of the trend of outsourcing by
original equipment manufacturers (OEMs) in the telecommunications and computer
industries. Process improvements and cost reduction also contributed to the
improved results. The Company is responding to the strong demand by investing in
product development and expanding production capacity.
 
  Fiscal Year 1997 Compared To 1996
 
     Total sales and operating profit for fiscal year 1997 were $4.18 billion
and $369.6 million, respectively, representing increases of 16% and 15%,
respectively, over the prior year's results. Net earnings increased 7% to $162.0
million after an increase in interest expense for fiscal year 1997 compared with
net earnings of $150.9 million for fiscal year 1996.
 
     The increase in sales and operating profit for the Advanced Electronics
segment primarily reflected the acquisitions of Sperry Marine Inc. ("Sperry
Marine"), a leading supplier of marine electronic navigation and guidance
systems, in May 1996 and Decca, a provider of marine electronic equipment, in
February 1997. The combined technologies and capabilities of Sperry Marine and
Decca have enabled the Company to provide systems-wide solutions to the marine
markets for both defense and commercial applications. Backlog for the Advanced
Electronics segment was $1.61 billion at July 31, 1997 compared with $1.66
billion at July 31, 1996.
 
     Sales and operating profit for the Information Systems segment were
significantly higher primarily as a result of the acquisition of PRC in February
1996. PRC is a diversified information technology company that designs,
develops, integrates and supports computer-based information handling and
processing systems and reengineers business processes for the U.S. Government
and other customers. PRC generates a significant portion of its revenues from
providing systems integration and computer-based solutions to the non-defense
federal, state and local government markets. The Company also strengthened its
position in the electronic display market with the acquisition of SAIT in March
1997. SAIT provides customized and ruggedized mobile computing equipment and
systems for commercial and military operations worldwide. Firm backlog for the
Information Systems segment at July 31, 1997 amounted to $518.1 million compared
with $569.2 million at July 31, 1996. In addition, PRC had unfunded backlog with
potential contract values totaling approximately $1.5 billion at July 31, 1997
compared with $1.0 billion at July 31, 1996.
 
     Sales for the Marine Engineering and Production segment for fiscal year
1997 decreased due to a lower level of construction activities as a result of
contracts being completed, including two Aegis destroyers during each of fiscal
years 1997 and 1996 and a fifth LHD class amphibious assault ship in fiscal year
1997. This decline was partially offset by other contracts moving into more
advanced stages of production and the startup of production on a seventh LHD
class amphibious assault ship. Operating margins improved as a result of
increased earnings rates on programs maturing in the production process and
continued cost reduction efforts. During fiscal year 1997, the U.S. Navy awarded
the Company a contract to begin advance procurement of material to be used in
the construction of Aegis destroyers, for which a contract to build six
additional Aegis destroyers, along with options for two more, was awarded during
fiscal year 1998. The Company also received two contract awards in fiscal year
1997 to build multiple offshore supply vessels for a customer in the commercial
ship chartering industry. Backlog for the Marine Engineering and Production
segment at July 31, 1997 was $3.23 billion compared with $3.29 billion at July
31, 1996.
 
     The Electronic Components and Materials segment contributed with improved
sales and operating profit in fiscal year 1997. This segment benefited from the
growth in the markets which it serves, particularly from the strong demand in
the telecommunication-related markets for its commercial electronic products.
Cost reduction efforts and process improvements have also contributed to the
improved operating margins.
 
                                       10
<PAGE>   13
 
  Liquidity and Capital Resources
 
     In connection with the acquisition of TASC in April 1998, the Company
issued $100 million principal amount of 6.05% Senior Notes due 2003, $200
million principal amount of 6.75% Senior Debentures due 2018 and sold commercial
paper (see Note C). The aforementioned borrowings incurred for the acquisition
of TASC as well as borrowings in connection with a payment of prior years' taxes
were the primary reasons for the increase in interest expense in fiscal year
1998 compared with 1997. During the year, cash flow from operations provided the
funds to meet operating needs, make capital expenditures and repurchase 822,100
shares of Common stock. During fiscal year 1998, the Company entered into a new
revolving credit agreement totaling $400 million which serves as a back-up
facility for its commercial paper program. The Company also has unused credit
commitments of $400 million under a revolving credit agreement with various
banks available for its general use and replacement of existing debt.
 
  Environmental Matters
 
     As previously reported, the Company or certain of its divisions or
subsidiaries has been named as a potentially responsible party in respect to
various sites to which certain of its operations may have contributed wastes.
Also, the Company and certain of its divisions and subsidiaries have incurred
costs, which have not had a material impact on the Company's consolidated
financial statements in any one year, for cleaning up a number of sites now or
formerly owned or leased by the Company. At this time, the Company believes that
its ultimate liability for additional expenditures associated with such owned or
leased sites and other sites to which it may have contributed wastes will not
have a material adverse effect on its consolidated financial position. In the
first quarter of fiscal year 1998, the Company adopted Statement of Position
96-1 ("SOP 96-1"), "Environmental Remediation Liabilities", issued by the
American Institute of Certified Public Accountants. The adoption of SOP 96-1 did
not have an impact on the Company's results of operations or financial position.
 
  Market Risk Disclosure
 
     The Company has exposures to interest rate risk primarily from its
short-term and long-term borrowings and to exchange rate risk with respect to
its foreign operations and from foreign currency transactions. In general, the
Company's long-term borrowings are fixed rate debt and the short-term borrowings
are variable rate debt. See Note C for components of the Company's short-term
and long-term obligations. At July 31, 1998, the carrying value of the long-term
fixed rate borrowings was $699.5 million compared with an estimated fair value
of $731.8 million. If the interest rates were 10% lower, the projected fair
value at July 31, 1998 would have been $789.3 million. Based on short-term
borrowings outstanding at July 31, 1998 and the weighted-average interest rates
related to such borrowings as of July 31, 1998, a hypothetical 10% increase to
the interest rates would not have a significant impact on the Company's results
of operations or cash flows.
 
     The Company from time to time enters into foreign currency exchange
contracts to hedge certain foreign currency transactions and commitments and to
reduce its exposure resulting from investments in certain foreign operations.
These contracts were not significant at July 31, 1998. A hypothetical 10% change
in the relevant currency rates at July 31, 1998 would not have a material impact
on the Company's results of operations or cash flows.
 
  Year 2000
 
     The Company has developed plans and a program to address the potential
impact of the Year 2000 on its business systems, facilities and products which
may include imbedded software. Each of these areas has been inventoried for
potential Year 2000 impact. Detailed implementation plans are in place for the
required modifications or replacements. The process and progress is monitored on
a regular basis by a special corporate task group of management, audit and legal
personnel and reported to management and the Audit and Compliance Committee of
the Board of Directors. Implementation of the required changes to critical
systems, facilities and products is expected to be completed during fiscal year
1999. The Company is in contact with major suppliers and customers and is
developing backup and contingency plans both in relation to internal
 
                                       11

systems, facilities and products and third parties. Incremental costs to address
and achieve Year 2000 compliance are expensed as incurred. Such costs are
approximately $9 million through July 31, 1998 and expected to total $22
million. In addition, the Company has continued its process of replacing
manufacturing and business systems with more efficient and technologically up to
date systems that are also Year 2000 compliant. The Company believes it is
taking reasonable steps to prevent a material adverse operational or financial
impact from a non-compliant situation. The effect, if any, on the Company's
results of operations if the Company, any of its customers or suppliers is not
Year 2000 compliant is not reasonably estimable. This discussion contains
forward-looking statements containing such words as "expected", "estimated",
"believes" and "reasonably estimable". The actual results may differ if
implementation plans, the backup and contingency plans are not implemented by
third parties or the information provided by third parties is incorrect.

              MANAGEMENT'S RESPONSIBILITY FOR FINANCIAL REPORTING
 
     The consolidated financial statements of Litton Industries, Inc. and
subsidiary companies, and related financial information included in this Annual
Report, have been prepared by the Company, whose management is responsible for
their integrity. These statements, which necessarily reflect estimates and
judgments, have been prepared in conformity with generally accepted accounting
principles.
 
     The Company maintains a system of internal controls to provide reasonable
assurance that assets are safeguarded and transactions are properly executed and
recorded. As part of this system, the Company has an internal audit staff to
monitor the compliance with and the effectiveness of established procedures.
 
     Deloitte & Touche LLP, an independent auditing firm, is engaged to audit
the consolidated financial statements of the Company and issue a report thereon.
They have informed management and the Audit and Compliance Committee of the
Board of Directors that their audits were conducted in accordance with generally
accepted auditing standards that require a review and evaluation of internal
controls to determine the nature, timing, and extent of audit testing. The
Independent Auditors' Report is on page F-2 of this report.
 
     The Audit and Compliance Committee of the Board of Directors, which
consists solely of directors who are not employees of the Company, meets
periodically with management, the independent auditors and the Company's
internal auditors to review the scope of their activities and reports relating
to internal controls and financial reporting matters. The independent and
internal auditors have full and free access to the Audit and Compliance
Committee and meet with the Committee both with and without the presence of
Company management.

                          INDEPENDENT AUDITORS' REPORT
 
Board of Directors and Shareholders
Litton Industries, Inc.
Woodland Hills, California
 
     We have audited the accompanying consolidated balance sheets of Litton
Industries, Inc. and subsidiary companies as of July 31, 1998 and 1997, and the
related consolidated statements of operations, shareholders' investment, and
cash flows for each of the three years in the period ended July 31, 1998. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Litton Industries, Inc. and
subsidiary companies as of July 31, 1998 and 1997, and the results of their
operations and their cash flows for each of the three years in the period ended
July 31, 1998 in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE A:  SIGNIFICANT ACCOUNTING POLICIES
 
     PRINCIPLES OF CONSOLIDATION  The accounts of Litton Industries, Inc. and
its wholly-owned subsidiaries (the "Company" or "Litton") are included in the
accompanying consolidated financial statements. Intercompany accounts and
transactions have been eliminated. Certain reclassifications of prior period
information were made to conform to the current year presentation.
 
     USE OF ESTIMATES  The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions, including estimates of anticipated contract costs and
revenues utilized in the earnings recognition process, that affect the reported
amounts in the financial statements and accompanying notes. Due to the inherent
uncertainty involved in making estimates, actual results could differ from those
estimates.
 
     CASH AND MARKETABLE SECURITIES  Cash and marketable securities consist of
the following:

     Cash equivalents consist of securities purchased within three months of
their maturity date and amounted to $16.2 million and $4.1 million in time
deposits at July 31, 1998 and 1997, respectively.
 
     The Company's marketable securities at July 31, 1998 and 1997 consisted of
obligations issued by the U.S. Government with an estimated fair market value of
$19.4 million for both periods, based on quoted market prices, compared with a
carrying amount of $15.8 million for both periods. These investments have been
classified as held-to-maturity securities.
 
     EARNINGS PER SHARE  The Company adopted Statement of Financial Accounting
Standards No. 128, "Earnings per Share" ("SFAS 128"), during fiscal year 1998.
SFAS 128 replaced the previously reported primary and fully diluted earnings per
share ("EPS") with basic and diluted EPS. Basic EPS is calculated based on the
weighted-average number of shares outstanding and diluted EPS includes the
effects of dilutive potential common shares. EPS amounts for prior periods
presented have been restated to conform to the requirements of SFAS 128.
 
     The following table sets forth the computation of basic and diluted
earnings per share:

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     INVENTORIES, LONG-TERM CONTRACTS AND REVENUE RECOGNITION  Inventory costs
under long-term contracts generally reflect actual or average costs and include
general and administrative costs of the Marine Engineering and Production
segment. For the Company's other business segments, general and administrative
costs are expensed as incurred. Inventories other than costs under long-term
contracts are stated at the lower of cost or market, generally using the average
or actual cost method. Progress payments received are first offset against the
related balance of unbilled receivables and inventories with any remainder
included in "Contract liabilities and customer deposits".
 
     Product revenues and profits on long-term contracts, performed over
extended periods of time, are recognized under the percentage-of-completion
method of accounting, principally based on direct labor dollars incurred for the
Marine Engineering and Production segment and generally on the costs incurred or
units-of-delivery basis for the Company's other operations. Service revenues
from fixed price and fixed price incentive contracts are recognized under the
percentage of completion method on the basis of costs incurred to estimated
total costs. Service revenues on cost reimbursement type contracts and time and
materials contracts are recognized as costs are incurred or as work is
performed. Revenues and profits on long-term contracts are based on the
Company's estimates to complete and are reviewed periodically, with adjustments
recorded in the period in which the revisions are made. Any anticipated losses
on contracts are charged to operations as soon as they are determinable.
 
     RESEARCH AND DEVELOPMENT  Worldwide expenditures on research and
development activities amounted to $233.8 million, $241.8 million and $217.0
million, of which 33%, 29% and 30% was Company-sponsored, in the years ended
July 31, 1998, 1997 and 1996, respectively. Company-sponsored research and
development expenditures are charged to expense as incurred.
 
     PROPERTY, PLANT AND EQUIPMENT  Investment in property, plant and equipment
is stated at cost. Allowances for depreciation and amortization, computed
generally by the straight-line method for financial statement purposes, are
provided over the estimated useful lives of the related assets.
 
     FOREIGN CURRENCIES  The currency effects of translating the financial
statements of those non-U.S. subsidiaries and divisions of the Company which
operate in local currency environments are included in the "Cumulative currency
translation adjustment" component of Shareholders' Investment. Gains and losses
resulting from foreign currency transactions are included in results of
operations and were not material in each of the three years in the period ended
July 31, 1998.
 
     GOODWILL AND OTHER INTANGIBLES  For financial statement purposes, goodwill
and other intangibles are generally amortized using the straight-line method
over their estimated useful lives, not exceeding 40 years. Goodwill at July 31,
1998 and 1997 was $1,064.6 million and $722.0 million, respectively. The current
and future profitability of the operations to which the goodwill relates are
evaluated at least annually. These factors, along with management's plans with
respect to the operations and the projected undiscounted cash flows, are
considered in assessing the recoverability of the goodwill.
 
     ENVIRONMENTAL COSTS  Provisions for environmental costs are recorded when
the Company determines its responsibility for remedial efforts or environmental
liability and such amounts are reasonably estimable. The Company's exposure may
be mitigated by potential insurance reimbursements and recovery under the
Company's U.S. Government contracts, to the extent recoverable. These
reimbursements and recoveries are not recorded until collection is probable.
 
     FINANCIAL INSTRUMENTS  In addition to the previously discussed cash and
marketable securities and certain long-term notes and debentures discussed in
Note C, the Company's other financial instruments include accounts receivable,
accounts payable, short-term debt and other miscellaneous long-term assets and
liabilities. The carrying amounts of the short-term assets and liabilities
approximate their market values due to their short maturity. Differences between
the recorded amounts and market value of the remainder of the financial
instruments were not material. The Company, from time to time, enters into
foreign currency

                            LITTON INDUSTRIES, INC.
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
exchange contracts to reduce its exposure resulting from net investments in
certain foreign operations. Gains and losses are included in "Cumulative
currency translation adjustment". There were no outstanding contracts at July
31, 1998 and 1997. The Company also occasionally enters into foreign currency
exchange contracts to hedge certain foreign currency transactions and firm
commitments. The aggregate notional amounts of these contracts were not material
at July 31, 1998 and 1997. As discussed in Note I, the Company also has off-
balance sheet guarantees and letter of credit agreements with notional values
totaling $453 million at July 31, 1998, relating principally to the guarantee of
future performance on foreign government contracts.
 
     OTHER NEW ACCOUNTING STANDARDS  In June 1998, the Financial Accounting
Standards Board ("FASB") issued Statement of Financial Accounting Standards
("SFAS") No. 133, "Accounting for Derivative Instruments and Hedging
Activities", which requires that all derivatives be recognized as assets or
liabilities in the consolidated balance sheet and measured at fair value. SFAS
133 is effective for the Company starting in its fiscal year 2000, but currently
is not expected to have a significant impact.
 
     In February 1998, the FASB issued SFAS No. 132, "Employers' Disclosures
about Pensions and Other Postretirement Benefits -- an amendment of FASB
Statements No. 87, 88 and 106", which revises the disclosure requirements for
pensions and other postretirement benefits. SFAS 132 is effective for the
Company starting in its fiscal year 1999.
 
     In 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information", which establishes new requirements on the
reporting of information about operating segments, products and services,
geographic areas and major customers. Although SFAS 131, which is effective for
the Company starting in its fiscal year 1999, will require additional reporting
and expanded disclosures, the Company does not anticipate significant changes to
its reportable segments.
 
     In 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive Income",
which establishes standards for reporting and display of comprehensive income
and its components. Comprehensive income includes "all changes in equity during
a period except those resulting from investments by owners and distributions to
owners". SFAS 130 is effective for the Company starting in its fiscal year 1999
and is expected to impact the Company's reporting of currency effects from
translating the financial statements of non-U.S. subsidiaries and divisions
currently included as a component of Shareholders' Investment.
 
NOTE B:  ACQUISITIONS
 
     On April 1, 1998, the Company acquired TASC from Primark Corporation for a
preliminary purchase price of $432 million in cash. TASC, with revenues of
approximately $440 million for its fiscal year ended December 31, 1997, is a
leading provider of information technology and services to the national
intelligence sector, the Department of Defense and non-defense and commercial
customers. The acquisition has been accounted for under the purchase method of
accounting and reflected herein based upon preliminary allocations of the
purchase price which is subject to finalization.
 
     During fiscal year 1997, the Company completed the acquisitions of Decca
and SAIT. Decca, headquartered in the U.K., provides diverse marine electronic
equipment, including radars, electronic chart systems, chart video plotting
systems and bridge monitoring systems. SAIT manufactures customized and
ruggedized mobile computing equipment and systems for military and commercial
applications worldwide. Acquisitions made during fiscal year 1996 included PRC
and Sperry Marine. PRC is a diversified information technology company that
designs, develops, integrates and supports computer-based information handling
and processing systems and reengineers business processes for the U.S.
Government, commercial customers and state and local governments. Sperry Marine
is a provider of advanced electronic navigation and guidance systems to
commercial and military customers for marine uses. Other acquisitions made
during each of the three fiscal years ended July 31, 1998 are considered
integral to the Company's goals, but did not significantly affect the
consolidated financial statements.

NOTE H: PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS
 
     PENSION BENEFITS  The majority of the Company's U.S. employees are covered
by contributory defined benefit plans under which employees are eligible for
benefits at age 65. Generally, benefits are determined under a formula based
primarily on the participant's total plan contributions. The Company's funding
policy is to make annual contributions to the extent such contributions are
actuarially determined and tax deductible.
 
     The Company has a defined contribution voluntary savings plan for eligible
U.S. employees. This 401(K) plan is designed to enhance the existing retirement
programs for participating employees. The Company matches 50% of a certain
portion of participants' contributions to the plan. Additionally, PRC and TASC
have various defined contribution pension plans covering substantially all of
their employees, some of which provide for discretionary contributions.
 
     The Company's non-U.S. subsidiaries also have retirement plans for
long-term employees. These plans are not considered to be significant
individually or in the aggregate to the Company's consolidated financial
position. The pension liabilities and their related costs are computed in
accordance with the laws of the individual nations and appropriate actuarial
practices.
 
     A summary of the components of net periodic pension income (cost) for the
U.S. defined benefit plans and costs for defined contribution plans and non-U.S.
pension plans for fiscal years 1998, 1997 and 1996 is as follows:

     Actuarial assumptions used to measure the accumulated postretirement
benefit obligation include a discount rate of 7 1/4% and 7 3/4% at July 31, 1998
and 1997, respectively. The assumed health care cost trend rate for fiscal year
1999 is 9.33%, decreasing over 19 years to 6% where it is expected to remain
thereafter. The assumed health care cost trend rates for fiscal years 1998 and
1997 were 9.5% and 10.3%, respectively, decreasing over 20 and 21 years,
respectively, to 6%. The effect of a one-percentage-point increase in the
assumed health care cost trend rate on the service cost and interest cost
components of the net periodic postretirement benefit cost is not material. A
one-percentage-point change in the assumed health care cost trend rate would
impact the accumulated benefit obligation by approximately $13.2 million.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE I:  DEFENSE CONTRACTS, LITIGATION AND CONTINGENCIES
 
     Approximately 66%, 67% and 71% of total sales and service revenues of the
Company for the years ended July 31, 1998, 1997 and 1996 were from U.S.
Government contracts and subcontracts. Approximately 70% of these revenues for
1998 related to fixed-price type contracts. As is common with U.S. Government
contracts, the Company's U.S. defense contracts are unilaterally terminable at
the option of the U.S. Government with compensation for work completed and costs
incurred. Contracts with the U.S. Government are subject to certain laws and
regulations, the noncompliance with which may result in various sanctions. In
the current government contracting environment, contractors, sometimes without
their knowledge, are subject to investigations by the U.S. Government initiated
in various ways. Most investigations result in no action being taken or
administrative resolution. Litton is aware of ongoing investigations and is
cooperating in those investigations. Should any investigation result in the
filing of formal charges against the Company by the U.S. Government, disclosure
will be made if the amount involved or the relief sought is deemed by the
Company to be material.
 
     Litton is suing Honeywell, Inc. ("Honeywell") for patent infringement
relating to the manufacture of ring laser gyro navigation systems which are used
in commercial aircraft. After trial of that case in the U.S. District Court for
the Central District of California, on August 31, 1993, the jury rendered a
verdict in favor of Litton in the amount of $1.2 billion. On January 9, 1995,
the District Court released a Memorandum of Decision finding Litton's patent
invalid and rejecting the jury verdict. Litton appealed to the U.S. Court of
Appeals for the Federal Circuit. On July 3, 1996, the Court of Appeals rendered
a decision reversing the District Court's decision, finding the patent valid and
infringed by Honeywell. The Court of Appeals reinstated the jury's verdict on
liability including the findings of interference with contract and prospective
business advantage and ordered a new trial on the amount of damages sustained by
Litton in the District Court. On March 17, 1997, the U.S. Supreme Court vacated
the Court of Appeals ruling and remanded the case to the Court of Appeals for
further consideration in view of the Supreme Court's decision in Warner-Jenkins
Co. v. Hilton Davis Chemical Co. On April 7, 1998, the Court of Appeals
reinstated its finding that the patent was valid and ordered a new trial on both
liability and damages for the patent and interference with contract and
prospective business advantage claims. The Company has requested a trial date in
December of 1998.
 
     Litton is also suing Honeywell on antitrust grounds in the same U.S.
District Court. On February 29, 1996, a jury rendered a verdict in favor of
Litton. On July 25, 1996, the District Court upheld the jury's verdict that
Honeywell attempted to illegally monopolize and did monopolize the market for
inertial reference systems for large commercial air transport, commuter and
business aircraft. However, the District Court declined to enter the $234
million jury verdict on the basis that Litton's damage study as presented failed
to disaggregate damages between illegal and legal acts. A new trial limited to
the issue of the amount of damages sustained by Litton attributable to
Honeywell's unlawful conduct has been ordered by the District Court. The
District Court set a trial date of October 28, 1998.
 
     There are various other litigation proceedings in which the Company is
involved. Although the results of litigation proceedings cannot be predicted
with certainty, it is the opinion of the General Counsel that the ultimate
resolution of these other proceedings will not have a material adverse effect on
the Company's financial statements.
 
     The Company has issued or is a party to various guarantees and letter of
credit agreements totaling $453 million at July 31, 1998, relating principally
to the guarantee of future performance on foreign government contracts.

NOTE J:  BUSINESS SEGMENT REPORTING
 
     The Company's primary operations are reported in the following four
segments: Advanced Electronics, Information Systems, Marine Engineering and
Production, and Electronic Components and Materials. The Information Systems
businesses, formerly reported with the Advanced Electronics segment, have been
reported as a separate segment effective August 1, 1997. Accordingly, the
segment information for fiscal years 1997 and 1996 as presented herein has been
restated to reflect this change.
 
     The Advanced Electronics segment designs, develops and manufactures
inertial navigation, guidance and control, IFF (identification friend or foe)
and marine electronic systems. This segment also provides command, control and
communications and electronic warfare systems and integrates avionics systems
and shipboard information and communication systems.
 
     The Information Systems segment designs, develops, integrates and supports
computer-based information systems and provides information technology and
services. This segment is also engaged in the reengineering of business
processes.
 
     The Marine Engineering and Production segment is engaged in the building of
large multimission surface combatant ships and is a provider of overhaul,
repair, modernization, ship design and engineering services.
 
     The U.S. Government is a significant customer of the Advanced Electronics,
Information Systems and Marine Engineering and Production segments (see Note I).
 
     The Electronic Components and Materials segment is an international
supplier of laser crystals, connectors, mutilayer circuit boards, solder
materials and other electronic components used primarily in the
telecommunication, industrial and computer markets.
 
     Export sales were $578.3 million, $489.1 million and $406.8 million in
fiscal years 1998, 1997 and 1996, respectively. Intersegment sales and sales
between geographic areas are not material. All internal sales and transfers are
based on negotiated prices.
 
     Costs for Corporate, Interest and Other include unallocated expenses and
net interest expense, and its assets consist primarily of cash, marketable
securities and deferred tax assets.
