PART II

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
         RESULTS OF OPERATIONS.

RESULTS OF OPERATIONS

Overview

         The Company's business is both capital intensive and volume sensitive,
making capacity planning and efficient capacity use imperative.  Physical
capacity, utilization of this physical capacity, yields and average unit sales
price constitute the key determinants of the Company's profitability.  Of these
key determinants, price and utilization are the most sensitive to changes in
product demand.  If capacity and product price are fixed at a given level and
demand is sufficient to support a higher level of output, then increased output
attained through improved utilization rates and higher manufacturing yields
will translate directly into increased sales and improved gross margins.
Alternatively, if demand for the Company's products decreases, falling average
selling prices and lower capacity utilization could adversely effect the
results of the Company's operations.


Comparisons of 1994, 1993 and 1992 Results of Operations

         The Company's consolidated results of operations for 1994 represent
the Company's thin-film media operations exclusively.  In contrast, results of
operations for 1993 and 1992 consolidate the operating results of the Company's
thin-film media operations and Dastek, Inc., the Company's thin-film head joint
venture with Asahi Glass America, Inc. ("Asahi America").  In the fourth
quarter of 1993, the Company recorded a $39.0 million restructuring charge
related to the cessation of Dastek's inductive thin-film head operations.
Approximately one-half of the restructuring charge provided for estimates of
losses to be incurred during the 1994 wind down of Dastek's operations.  The
remaining charge primarily represented reductions of assets and liabilities to
their estimated net realizable value.  Dastek ceased all production activities,
sold all of its assets at various public auctions, concluded settlements with
its creditors, and was dissolved in 1994.  Based upon results of these actual
shutdown activities, no significant adjustment was required to the aggregate
restructuring charge recorded in 1993.  Actual operating losses incurred in
1994 were approximately one-third higher than estimated in the 1993
restructuring charge.  However, net losses from the sale of Dastek's assets and
the settlement of its liabilities were lower by a comparable amount.

         The following discussion compares the 1994, 1993 and 1992 results of
operations, excluding the results of Dastek, as presented above.


1994 vs. 1993

Net Sales

         Unit sales of thin-film media increased nearly 40% in 1994 relative to
1993. The effect on thin-film media revenue from this substantial increase in
unit sales volume was reduced by a 16% decrease in the overall average unit
selling price between the years. Declining prices are characteristic of the hard
disk drive industry and maintenance of the overall average selling price
generally occurs only as the result of product mix shifts to higher-priced, more
technologically advanced products. In 1994, the Company began a transition to
more advanced 1800 Oe product offerings. The transition to this high performance
disk was more challenging and required more time than previous product
transitions. Shipments for qualification of these products began in the third
quarter of 1994 and the Company exited the year with unit sales of these
higher-priced, higher-density products accounting for approximately 14% of unit
sales volume. As a result of the more lengthy product transition time, the
effects of traditionally declining prices for individual product offerings
reduced the overall average selling price between the years. In addition to the
slow transition to 1800 Oe disks, a portion of the decrease in the overall
average selling price was attributable to sales price reductions made in the
first quarter of 1994 in conjunction with the Company's long-term strategy to
increase market share. Industry demand for high performance 1800 Oe disks
currently exceeds industry supply. The Company plans to aggressively ramp its
production of this product class in 1995 at both its U.S. and Malaysian
facilities, exiting the year with over 80% of unit shipments in this product
class. Successful execution of this product transition should mitigate the
decline in the overall average selling price in 1995.


                                      4
<PAGE>   5
         Distribution sales of product manufactured by Asahi Komag Co., Ltd.
("AKCL"), the Company's Japanese thin-film media joint venture with Asahi Glass
Co., Ltd., decreased to $9.4 million in 1994 from $17.1 million in 1993. The
Company purchased smaller quantities of product from AKCL in 1994 as demand
within the Japanese thin-film media market absorbed more of AKCL's capacity. The
Company anticipates that distribution sales of AKCL product in 1995 will be
minimal.

         The increase in unit production volume required to support the increase
in unit sales volume for 1994 relative to 1993 was primarily achieved through a
combination of increased capacity and improved production yields and utilization
rates. Approximately 80% of the increase in unit production volume in 1994
relative to 1993 was provided through increases in effective production
capacity. Improvements in yields and utilization rates accounted for the
remaining increase in unit production volume. Historically, the Company has
increased effective production capacity through the addition of new production
lines and implementation of process improvement programs designed to improve
unit output of existing production lines. Successful process improvement
programs provide capacity increases at a significantly lower cost than the
addition of physical capacity. Shortened sputtering cycle times and other
process improvements provided approximately 40% of the 80% increase in effective
production capacity in 1994 relative to 1993. The addition of the Company's
eleventh, twelfth and thirteenth sputtering lines in October 1993, January 1994
and August 1994, respectively, provided the remainder of the increase in
production capacity between the years.

         During the fourth quarter of 1994, the Company began a series of
process improvements designed to support production of future advanced disk
products. These improvements should enhance product performance and should
enable increased unit output through reduced process cycle times. As part of
this program the Company removed one of its thirteen sputtering machines from
production in early November in order to retrofit the machine. Lost unit output
from the removal of this line, coupled with increased unit output from reduced
sputtering cycle times on certain of the Company's existing lines and the full
use of a new sputtering line installed in the third quarter of 1994, resulted in
a small sequential decrease in unit output in the fourth quarter relative to the
third quarter of 1994.

         In 1995 the Company expects to commence production on its fourteenth
and fifteenth production sputtering lines during the first and third quarters,
respectively. The Company plans to begin production on the first retrofitted
machine in the first quarter of 1995 but will sequentially convert three
additional sputtering lines during the year. As such, the return to production
of the retrofitted sputtering line will not increase the number of machines
available for production in 1995 relative to the fourth quarter of 1994.
Continued focus on process improvement programs, including further reductions in
sputtering cycle times, is expected to increase unit output beyond the
incremental output gains from the two new production lines.


Gross Margin

         The thin-film media gross margin percentage decreased to 32.0% for 1994
from 32.7% for 1993. Excluding distribution sales of product manufactured by
AKCL for resale to the Company's customers, the gross margin percentage
decreased to 32.7% from 34.1% between the years. The substantial decrease in the
overall average selling price outpaced solid improvements in the average unit
production cost and resulted in the lower gross margin percentage for 1994.
Manufacturing efficiencies, such as reduced cycle times and yield and
utilization improvements, were the primary drivers in reducing the average unit
production cost.

         The Company exited 1994 with net sales of $98.7 million, a 31.4% gross
margin and net income of $14.1 million in the fourth quarter. The Company
expects a slightly lower gross margin percentage on increased sales in the first
quarter of 1995 compared to the fourth quarter of 1994. A higher overall average
selling price is expected in the first quarter of 1995 due to a higher mix of
1800 Oe product. Unit 





                                      5
<PAGE>   6
output is also expected to increase in the first quarter of 1995 relative to the
fourth quarter of 1994. However, start-up costs to accelerate production of 1800
Oe products at the Company's Malaysian manufacturing facility during the first
quarter will most likely lead to a higher average unit cost of production.
Similar start-up costs were incurred during the fourth quarter of 1994 at the
Company's U.S. facilities. In addition, equipment transition issues will
continue to constrain U.S. production of 1800 Oe products for a portion of the
first quarter of 1995, thus increasing the cost of production. As a result of
the anticipated lower gross margin in the first quarter of 1995, the Company's
earnings may be relatively flat compared to the fourth quarter of 1994. The
Company anticipates that margin expansion and sequential earnings growth could
begin as early as the second quarter of 1995 with further acceleration during
the second half of 1995. Increased sales and earnings in 1995 will depend on
general industry conditions and the Company's ability to reduce cycle times,
successfully implement a series of equipment transitions, and cost-effectively
attain high volume production of 1800 Oe thin-film media.


Operating Expenses

         Research, development and engineering ("R&D") expenses increased $3.5
million in 1994 compared to 1993. The increase between the years was mainly due
to development costs for advanced thin-film media, including costs associated
with the Company's thin-film media pilot production line. Selling, general and
administrative ("SG&A") expenses increased $2.6 million in 1994 relative to
1993. SG&A expenses (excluding provisions for bad debt allowances, a
nonrecurring charge incurred in 1993 to terminate a patent dispute and the
Company's bonus and profit sharing programs) increased approximately $0.2
million. The increase was the net result of higher administrative costs to
support the growth in the business and a reduction of approximately $0.8 million
in legal and consulting costs in 1994 relative to 1993. Higher legal and
consulting costs were incurred in 1993 as a result of the patent dispute and
formation of the Company's Malaysian manufacturing facility. Provisions for bad
debt allowances decreased $0.1 million in 1994 compared to 1993. Provisions for
the Company's bonus and profit sharing programs increased $3.3 million between
the years due primarily to the higher operating profitability for the Company's
thin-film media operations.


Interest Income/Expense and Other Income

         Interest income increased $0.6 million in 1994 relative to 1993. The
increase was due to the combination of higher interest rates and higher average
investment balances in 1994. Interest expense decreased $1.1 million. In 1993,
the Company reversed previously capitalized interest related to the construction
of its thin-film media manufacturing facility in Malaysia, thus increasing 1993
interest expense. Excluding this reversal, interest expense decreased $0.2
million primarily due to a lower average outstanding debt balance for 1994.
Approximately $0.3 million of the decrease related to lower charges for the
Company's interest rate swap agreement. Other income,net decreased $0.6 million
in 1994 mainly due to higher losses on disposal of equipment in 1994 relative to
1993.


Income Taxes

         The effective income tax rate for 1994 of 30% was lower than the 1994
combined federal and state statutory rate of 41% and the effective income tax
rate of 37% in 1993 primarily as a result of a tax holiday granted to the
Company's wholly-owned thin-film media operation in Malaysia. Komag USA
(Malaysia) Sdn. ("KMS") has been granted a five-year tax holiday by the
Malaysian government. The impact of the tax holiday was to increase net income
by approximately $6,400,000 ($0.28 per share) in 1994. Losses incurred prior to
the commencement of the tax holiday, approximately $6,237,000, are available for
carryforward to years following the expiration of the tax holiday. The Company
has generated $15,000,000 of pretax earnings for which no U.S. tax has been
provided. No U.S. tax has been provided on these earnings as the Company has no
plans to repatriate these funds to the U.S. The 





                                      6
<PAGE>   7
Company anticipates that the effective income tax rate for 1995 will decrease as
KMS installs additional capacity and generates a larger percentage of the
Company's consolidated profit than in 1994.


   
As of January 1, 1995 a 60% owned subsidiary of the Company, Dastek Holding 
Company, had a federal tax net operating loss carryforward of approximately 
$96 million. The Company has fully reserved for the potential future federal 
tax benefit of this net operating loss in the deferred tax asset valuation 
allowance due to the fact that its utilization is limited to the subsidiary's 
separately computed future taxable income and that the subsidiary has no 
history of operating profits.
    

Minority Interest in Consolidated Subsidiary/Equity in Unconsolidated
Joint
Venture

         The minority interest in the net income of consolidated subsidiary
represented Kobe Steel USA Holdings Inc.'s ("Kobe USA") 45% share of Komag
Material Technology, Inc.'s ("KMT's") net income. KMT recorded net income of
$2.4 million and $1.1 million in 1994 and 1993, respectively.

         The equity in net income of unconsolidated joint venture reflected the
Company's 50% interest in AKCL's net income. AKCL reported net sales and net
income of $131.3 million and $11.0 million for 1994, up from $119.4 million and
$9.8 million for 1993. AKCL's functional currency is the Japanese yen. The
Company translates AKCL's yen-based income statements to U.S. dollars at the
average exchange rate in effect for each quarterly period. The Japanese yen
strengthened approximately 8% in 1994 relative to 1993. AKCL's net sales and net
income would have been approximately $120.4 million and $10.0 million,
respectively, in 1994 had the yen-based income statement been translated at the
average rate in effect for 1993.

         AKCL invested in Headway Technologies, Inc. ("Headway") in the third
quarter of 1994 and recorded a partial writedown ($0.5 million, net of tax) of
its investment in Headway in the fourth quarter of 1994. Headway is a
development stage company and AKCL will continue such writedowns until Headway
emerges from the development stage. These partial writedowns are a function of
losses incurred at Headway. Fifty percent of this writedown is included in the
Company's equity in net income of unconsolidated subsidiary on the Consolidated
Statement of Operations for 1994.


Other

         The Company operates facilities in the U.S. and Malaysia and sells
products in a variety of international locations. In order to minimize the risks
associated with foreign currency fluctuations, the Company denominates its sales
in U.S. dollars and periodically enters into foreign exchange contracts to hedge
firm purchase commitments. No such foreign exchange contracts were open as of
January 1, 1995. Gains and losses created by the remeasurement of the financial
statements of the Company's Malaysian operations into U.S. dollars from
Malaysian ringgits have not had a significant effect on the consolidated results
of operations.

         The January 1995 earthquake in Kobe, Japan, has had little, if any,
effect on the Company's operations. AKCL's facilities, located approximately 370
miles northeast of the city of Kobe, were unaffected by the earthquake. Kobe
Steel Co., Ltd's manufacturing facility for aluminum substrate blanks, located
approximately 300 miles northeast of the city of Kobe, did not sustain any
quake-related damage. Other Japanese vendors in the general Kobe-Osaka area
remain in operation and are using alternative shipping methods to deliver their
products.

   
         In 1994 the Company adopted Financial Accounting Standard No. 115
"Accounting for certain Investments in Debt and Equity Securities". The adoption
of FAS 115 did not have a material impact on the Company's financial position or
results of operations. Beginning January 2, 1995, the Company will be required 
to adopt Statement of Financial Accounts Standard No. 121, "Accounting for the 
Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed." The 
Company does not expect the adoption of SFAS No. 121 to have a material impact 
on the Company's financial position or results of operations.

1993 vs. 1992

Net Sales

         The 20% increase in thin-film media revenue for 1993 relative to 1992
was primarily due to a 21% increase in unit sales volume in 1993. The overall
average unit selling price for media decreased only slightly between the years.
In 1993, sales mix shifts into higher-density product offerings largely offset
the effect of traditionally declining prices. Distribution sales of product
manufactured by AKCL decreased to $17.1 million in 1993 from $36.4 million in
1992. Increases in sales of the Company's internally produced media more than
offset the revenue decrease resulting from the lower distribution sales.

         Thin-film media unit production volume increased significantly in 1993
relative to 1992 and accounted for the majority of the increase in media unit
sales between the years. Capacity utilization and manufacturing yields were
relatively unchanged between the comparable years. The Company added its ninth
production sputtering line in April 1992 and a pilot production sputtering line
in December 1992. The availability of these lines for all of 1993 and the July
1993 addition of the Company's first sputtering line in Penang, Malaysia,
provided most of the increase in unit production output in 1993.


Gross Margin

         The media gross margin percentage increased to 32.7% in 1993 from 28.0%
in 1992. Excluding distribution sales of product manufactured by AKCL for resale
to the Company's customers, the gross margin percentage increased to 34.1% from
30.4% between the years. Process improvements resulting in higher media
production efficiency accounted for most of this increase. Additionally, the
Company's Malaysian thin-film media manufacturing facility, which incurred a
negative gross margin for 1992 related to the operation's start-up, generated an
improved but slightly negative gross margin for fiscal year 1993.


Operating Expenses

         Research, development and engineering expenses increased $4.7 million
(35%) in 1993 relative to 1992. The addition of the Company's thin-film media
pilot production line in December 1992 and focus on the development of advanced
thin-film media accounted for the majority of the increase. Selling, general and
administrative expenses increased $6.8 million in 1993 relative to 1992.
Provisions for the Company's bonus and profit sharing programs in 1993 increased
$3.0 million due to stronger results in the thin-film media operations while
provisions for doubtful accounts were $0.9 million higher in 1993 than in 1992.
Excluding these charges, selling, general and administrative expenses increased
$2.9 million. Of this amount approximately one-third of the increase related to
costs incurred in 1993 to terminate a patent dispute. Higher administrative
costs associated with the growth of the business, including the administration
costs for the Company's new Malaysian facility, accounted for the remainder of
the increase.


Interest Income/Expense and Other Income

         Interest income decreased $0.8 million in 1993 relative to 1992 due to
lower interest rates and a shift toward lower-yielding tax-exempt investments.
The average investment balance was relatively unchanged between the years.
Interest expense increased $2.2 million in 1993 relative to 1992 primarily due
to higher average outstanding debt balances and a reversal of previously
capitalized interest related to the Company's media manufacturing facility in
Malaysia. Other income in 1993 decreased $1.2 million from 1992. The decrease
was primarily due to the cessation of technology royalties from AKCL which ended
in the fourth quarter of 1992 upon reaching the contractual limit.


                                      8

Income Taxes

         The Company's tax provision for 1993 of 37.4% was slightly higher than
the 36.1% recorded for 1992. The higher effective tax rate primarily reflected
an increase in the federal statutory rate in effect for 1993.


Minority Interest in Consolidated Subsidiary/Equity in Unconsolidated Joint
Venture

         The minority interest in net income of consolidated subsidiary for 1993
represented Kobe USA's 45% share of KMT's net income for 1993. KMT recorded net
income of $1.1 million and $1.6 million in 1993 and 1992, respectively. The
Company's 50% share of AKCL's net income was recorded as equity in net income of
unconsolidated joint venture. AKCL reported sales and net income of $119.4
million and $9.8 million for 1993, up from $91.7 million and $6.4 million for
1992. The lower profitability in 1992 was due to AKCL operating below capacity
through the first half of the year.

         The yen strengthened approximately 10% in 1993 relative to 1992. AKCL's
net sales and net income for 1993 would have been approximately $105.6 million
and $8.8 million, respectively, had the yen-based income statement been
translated at the average rate in effect for 1992.


Comparison of Dastek's 1993 and 1992 Results of Operations

         Thin-film head revenue increased to $50.9 million in 1993 from $47.3
million in 1992. The increase in revenue in 1993 was primarily due to the
addition of headstack assembly production which began in late 1992. There was
also a slight increase in 1993 in the overall average selling price from a
combination of a unit sales mix shift to newer-generation microslider products
and favorable end-of-life pricing for minislider products. The negative gross
margin from thin-film head operations increased significantly relative to 1992
due to lower manufacturing product yields on newer-generation microsliders and
sharply lower unit sales volumes in the last half of 1993. Favorable market
conditions in the disk drive industry ended abruptly in mid 1993 and supply of
recording heads surpassed demand. As a result, the Company experienced a sharp
decrease in demand and intense pricing pressure from head manufacturers with
lower priced, older technology products. Additionally, delays in customer
qualification of new smaller-sized nanoslider thin-film heads in the fourth
quarter of 1993 negatively affected operating results. These significant market
changes and the resulting significant continuing operating losses resulted in
Dastek's decision in late 1993 to exit the inductive thin-film head business.



LIQUIDITY AND CAPITAL RESOURCES

         Consolidated cash and short-term investments of $93.9 million at the
end of 1994 increased slightly from $91.6 million at the end of 1993.
Consolidated operating activities generated $97.2 million in cash in 1994. The
winding down of Dastek's operations consumed $13.3 million in operating cash
flow during the year. Excluding Dastek's cash outflows, the Company generated
$110.5 million from its media operations and more than funded its $102.4 million
of capital spending for 1994. Sales of Common Stock under the Company's stock
option and stock purchase programs during this period generated $12.0 million,
while net repayments of short-term notes and long-term obligations used $17.5
million. Proceeds from the disposal of property, plant and equipment, primarily
related to dispositions of assets at Dastek, generated $12.1 million.





                                      9
<PAGE>   10
         Total capital expenditures for 1995 are currently planned at
approximately $150 million. Construction of a 230,000 square-foot manufacturing
plant on a 55 acre site in the Malaysian state of Sarawak, process improvement
programs in the U.S. and Malaysia, installation of two additional sputtering
lines and payments on an additional sputtering line (expected to be installed in
Malaysia in 1996) are the major components of the capital plan. Non-cancellable
commitments at January 1, 1995 total approximately $54.2 million.

         The Company believes that existing cash balances and credit facilities,
coupled with anticipated cash flow from operations, will fund its 1995 capital
spending plans and allow maintenance of adequate cash balances. The Company has
$80.0 million available under various revolving credit agreements including a
three-year term $35.0 million facility and two one-year term lines aggregating
$45.0 million. The Company will continue to review its cash requirements and
evaluate its need for additional financing.

                REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Stockholders
Komag, Incorporated

     We have audited the accompanying consolidated balance sheets of Komag,
Incorporated as of January 1, 1995 and January 2, 1994, and the related
consolidated statements of operations, stockholders' equity, and cash flows for
each of the three years in the period ended January 1, 1995. Our audits also
included the financial statement schedule listed in the Index at Item 14(a).
These financial statements and schedule are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements and schedule based on our audits. We did not audit the financial
statements of Asahi Komag Co., Ltd. (a corporation in which the Company has a
50% interest) as of January 1, 1995 and January 2, 1994, and for each of the
three years in the period ended January 1, 1995. Those financial statements were
audited by other auditors whose report has been furnished to us, and our
opinion, insofar as it relates to data included for Asahi Komag Co., Ltd. as of
January 1, 1995 and January 2, 1994, and for each of the three years in the
period ended January 1, 1995, is based solely on the report of the other
auditors.

     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 and the report of other auditors provide a reasonable
basis for our opinion.

     In our opinion, based on our audits and the report of other auditors, the
financial statements referred to above present fairly, in all material respects,
the consolidated financial position of Komag, Incorporated at January 1, 1995
and January 2, 1994, and the consolidated results of its operations and its cash
flows for each of the three years in the period ended January 1, 1995, in
conformity with generally accepted accounting principles. Also, in our opinion,
the related financial statement schedule, when considered in relation to the
basic financial statements taken as a whole, presents fairly in all material
respects the information set forth therein.

                               KOMAG, INCORPORATED
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Consolidation: The consolidated financial statements include the
accounts of the Company, its wholly-owned and majority-owned subsidiaries (see
Notes 9 and 10) and equity in its unconsolidated joint venture (see Note 11).
All significant intercompany accounts and transactions have been eliminated in
consolidation.

Foreign Currency Translation: The functional currency of the Company's
unconsolidated joint venture is the Japanese yen. Translation adjustments
relating to the translation of these statements are included as a separate
component of stockholders' equity and not included in net income. The functional
currency for the Company's Malaysian operation is the U.S. dollar. Remeasurement
gains and losses, resulting from the process of remeasuring these foreign
currency financial statements into U.S. dollars, are included in operations.

   
Foreign Exchange Gains and Losses: The Company enters into foreign currency
forward exchange contracts to reduce the impact of currency fluctuations on firm
purchase order commitments for equipment and construction-in-process. Gains and
losses related to these contracts are included in the cost of the assets
acquired. The Company had no foreign exchange contracts outstanding at 
January 1, 1995 or January 2, 1994. The Company had approximately $9 million of
unhedged Japanese yen based firm purchase commitments at January 1, 1995 and
January 2, 1994.
    

Cash Equivalents: The Company considers as a cash equivalent any highly liquid
investment that matures within three months of its purchase date.

Short-Term Investments: The Company invests its excess cash in high-quality,
short-term debt instruments. Short-term investments consist primarily of
AAA-rated, municipal auction rate preferred stock with maturities greater than
90 days; however, none of the Company's debt security investments have
maturities greater than one year.

In 1994 the Company adopted Statement of Financial Accounting Standard No. 115,
"Accounting for Certain Investments in Debt and Equity Securities" ("FAS 115").
Under FAS 115, the Company determines the appropriate classification of debt
securities at the time of purchase and reevaluates such designation as of each
balance sheet date. At January 1, 1995 all short-term investments are designated
as available for sale. Interest and dividends on the investments are included in
interest income. The adoption of FAS 115 did not have a material impact on the
Company's financial position or results of operations.

   
The following is a summary of the Company's investments by major security type
at amortized cost, which approximates fair value:

                                                        -------
</TABLE>

There were no realized gains or losses on the Company's investments during 1994
as all investments were held to maturity during the year.
    

Inventories: Inventories are stated at the lower of cost (first-in, first-out
method) or market.

Property, Plant and Equipment: Property, plant and equipment, except
construction-in-process, are stated at cost less accumulated depreciation and
amortization. Depreciation is computed by the straight-line method over the
estimated useful lives of the assets. The estimated useful life of the Company's
building is 30 years. Furniture and equipment are generally depreciated over 
5 years and leasehold improvements are amortized over the shorter of the lease
term or the useful life.







Revenue Recognition: The Company records sales upon shipment and provides an
allowance for estimated returns of defective products.

Research and Development: Research and development costs are expensed as
incurred.


                                       19
<PAGE>   20
Income Taxes: The provision for income taxes is based on pretax financial
accounting income. Deferred tax assets and liabilities are recognized for the
expected tax consequences of temporary differences between the tax and book
basis of assets and liabilities.

Income (Loss) Per Share: Income per share has been computed using the weighted
average number of shares of Common Stock and dilutive common stock equivalents
outstanding during the period. Common stock equivalents include shares issuable
upon the assumed exercise of options reflected under the treasury stock method.
Loss per share has been computed using the weighted average number of shares of
Common Stock outstanding during the period.

Reclassification: Certain reclassifications have been made to the 1993
Consolidated Balance Sheet, Statement of Cash Flows, and related notes to
conform to the current year presentation.

Fiscal Year: The Company uses a 52-53 week fiscal year ending on the Sunday
closest to December 31. The years ended January 1, 1995 and January 2, 1994 were
each comprised of 52 weeks and the year ended January 3, 1993 was comprised of
53 weeks.

NOTE 3.  STOCK OPTION PLANS AND STOCK PURCHASE PLAN

Under the Company's stock option plan ("Plan"), options to purchase up to
6,320,000 shares of Common Stock may be granted to key employees and directors.
The Plan provides for issuing both incentive stock options, which must be
granted at fair market value at the date of grant, and non-qualified stock
options, which may be granted at not less than 85% of fair market value at the
date of grant. Outstanding options generally vest over four years and expire no
later than ten years from the date of grant. Options may be exercised in
exchange for cash or outstanding shares of the Company's Common Stock.
Approximately 5,000 shares of the Company's Common Stock were received in
exchange for option exercises in 1994. No such exchanges occurred in 1993 or
1992. At January 1, 1995


                                       21
<PAGE>   22

approximately 880,000 options were available for grant and 3,172,000 shares of
Common Stock were reserved for future issuance under these Plans. At January 1,
1995 and January 2, 1994 approximately 641,000 and 959,000, respectively, of the
outstanding options were exercisable.

Under an option plan for employees of Dastek, Inc. ("Dastek"), a former joint
venture of the Company (see Note 9), options to purchase 1,000,000 shares of the
Company's Common Stock were authorized and reserved for issuance. At January 1,
1995, 230,000 options had been exercised and 50,000 options were exercisable
under the Dastek plan. No additional options will be granted under the Dastek
plan due to the cessation of Dastek's operations.

As of January 1, 1995 a 60% owned subsidiary of the Company, Dastek Holding
Company, had a federal tax net operating loss carryforward of approximately $96
million. The Company has fully reserved for the potential future federal tax 
benefit of this net operating loss in the deferred tax asset valuation 
allowance due to the fact that its utilization is limited to the subsidiary's
separately computed future taxable income and that the subsidiary has no
history of operating profits. The deferred tax asset valuation allowance
increased $7,308,000, $11,719,000 and $7,112,000 in fiscal years 1994, 1993 and
1992, respectively. The $96,000,000 net loss expires at various dates through
2010.
    

A reconciliation of the income tax provision at the federal statutory rate (35%
for 1994 and 1993; 34% for 1992) to the income tax provision at the effective
rate is as follows:

Foreign pretax income (loss) was $23,882,000, ($15,511,000) and ($6,424,000) in
1994, 1993 and 1992, respectively.

The Company's share of undistributed earnings of the Company's unconsolidated
joint venture (see Note 11 to Consolidated Financial Statements), for which the
Company has provided no U.S. income taxes, aggregate $16,600,000 net of Japanese
income taxes at January 1, 1995. These earnings are considered to be permanently
invested in the joint venture.

Komag USA (Malaysia) Sdn., the Company's wholly-owned thin-film media operation

commencing in July 1993. The impact of this tax holiday was to increase net
income by approximately $6,400,000 ($0.28 per share) in 1994. Losses incurred
prior to the commencement of the tax holiday, approximately $6,237,000, are
available for carryforward to years following the expiration of the tax holiday.
The Company has generated $15,000,000 of pretax earnings for which no U.S. tax
has been provided.

At January 1, 1995 long-term debt matures as follows: 1995--$13,232,000;
1996--$6,250,000; 1998--$10,000,000; no maturities occur in 1997.

The Company's credit facilities total $80,000,000 and include a three-year term
$35,000,000 line of credit and two one-year term lines aggregating $45,000,000.
The three-year term line of credit agreement expires in December 1997 but may be
extended, subject to bank approval, annually for an additional year, thus
perpetuating its three-year term. The entire $80,000,000 under these unsecured
credit facilities remains available.

Certain of the notes payable require the Company to maintain certain financial
ratios and comply with covenants which include a prohibition on the payment of
dividends.

At January 2, 1994, the Company had $3,000,000 of short-term debt payable to
banks bearing interest at 4.5%.

NOTE 7.  FAIR VALUE OF FINANCIAL INSTRUMENTS

Cash and Short-term Investments, Accounts Receivable and Certain Other
Liabilities: The carrying values on the Consolidated Balance Sheets approximate
fair value at January 1, 1995 and January 2, 1994 due to the relatively short
period to maturity of the instruments.

Debt: The carrying values on the Consolidated Balance Sheets approximate fair
value at January 1, 1995 and January 2, 1994. Rates currently available to the
Company for long-term borrowings with similar terms and remaining maturities
were used to estimate the fair value of existing borrowings as the present value
of expected cash flows.

Interest-Rate Swap Agreement: The Company uses an interest-rate swap agreement
to effectively convert a portion of its floating rate debt to a fixed rate
basis, thus reducing the impact of interest rate changes on future income.
Approximately 25% ($7,000,000) of the Company's variable rate term debt was
subject to the interest rate swap agreement at January 1, 1995. The Company
expensed $406,000, $709,000 and $812,000 under this agreement in 1994, 1993 and
1992, respectively. The fair value of the interest rate swap agreement,
estimated as the amount that the bank would receive to terminate the agreement,
was $91,000 at January 1, 1995.

NOTE 8.  LEASES AND COMMITMENTS

The Company leases most of its production facilities under operating leases that
expire at various dates between 1996 and 2001. Certain of these leases include
renewal options varying from five to ten years.

At January 1, 1995 the future minimum commitments for all non-cancellable
operating leases are as follows (in thousands):

Rental expense for all operating leases amounted to $4,319,000, $5,471,000 and
$5,173,000 in 1994, 1993 and 1992, respectively.

The Company has current non-cancellable capital commitments of approximately
$54,183,000.

NOTE 9.  DASTEK HOLDING COMPANY

In December 1991 the Company completed a merger with Dastek, Inc. ("Dastek"), a
manufacturer of thin-film magnetic recording heads for use in Winchester disk
drives. In February 1992, the Company formed a joint venture to produce and
market thin-film magnetic recording heads with Asahi Glass America, Inc. ("Asahi
America"), a U.S. subsidiary of Asahi Glass Co., Ltd. of Japan. Under the joint
venture agreement, the Company contributed to the joint venture both the stock
of Dastek and the assets of its existing thin-film head development program.
Asahi America in turn contributed to the joint venture nearly $60,000,000 in
cash and notes. The notes were paid to the joint venture in 1992 and 1993. Based
on these contributions, the Company and Asahi America obtained interests in the
joint venture of 60% and 40%, respectively. During 1993 the Company and a
subsidiary of Asahi America loaned the Dastek joint venture an additional
$24,000,000 and $16,000,000, respectively.

These loans were revalued to their estimated settlement amounts in late 1993 as
a result of the restructuring of the thin-film head operations. In December 1993
the Company recorded a one-time charge of $38,956,000 as a result of Dastek's
decision to exit the inductive thin-film head business. The net impact of the
restructuring charge, after related minority interest and income tax
adjustments, was $35,389,000 ($1.66 loss per share for the year ended January 2,
1994). Approximately one-half of the restructuring charge related to the
reduction of assets and liabilities to net realizable value. The remaining
portion provided for estimated operating losses to be incurred during the
completion of existing customer orders and the wind down of Dastek's operations.
Dastek ceased its inductive thin-film head operations, sold its equipment at
various public auctions, settled with its creditors and was legally dissolved
prior to the end of 1994. Based upon the results of these actual shutdown
activities, no significant adjustment was required to the aggregate
restructuring charge recorded in 1993. Actual operating losses incurred in 1994
were approximately one-third higher than estimated in the 1993 restructuring
charge. However, net losses from the sale of Dastek's assets and the settlement
of its liabilities were lower by a comparable amount.

NOTE 10.  KOMAG MATERIAL TECHNOLOGY, INC.

The Company's financial statements include the consolidation of the financial
results of Komag Material Technology, Inc. ("KMT"), which manufactures and sells
aluminum disk substrate products for high-performance magnetic storage media.
KMT is owned 55% by the Company and 45% by Kobe Steel USA Holdings Inc. ("Kobe
USA"), a U.S. subsidiary of Kobe Steel, Ltd. ("Kobe").

Under a joint venture agreement, Kobe has agreed to supply disk substrate blanks
to KMT while the Company has agreed to purchase KMT's entire output of finished
substrates. The Company also purchases finished substrates directly from Kobe or
its distributors. All parties have also agreed to conduct joint research on the
development of aluminum alloy-based blank finishing technologies.

Other transactions between Kobe or its distributors and the Company were as
follows:

NOTE 11.  UNCONSOLIDATED JOINT VENTURE

In 1987 the Company formed a partnership, Komag Technology Partners
("Partnership"), with the U.S. subsidiaries of two Japanese companies and
simultaneously formed a subsidiary, Asahi Komag Co., Ltd. ("AKCL"). The Company
contributed technology in exchange for a 50% interest in the Partnership, and
the subsidiaries of the Japanese companies contributed approximately 1.5 billion
yen (approximately $11 million) in exchange for a 50% interest in the
Partnership. The Partnership then contributed all the cash and licensed the
technology to AKCL in exchange for all of its stock and a limited royalty of 5%
of product produced and sold by AKCL. The Partnership and its subsidiary (joint
venture) established a facility in Japan to manufacture and sell the Company's
thin-film media products in Japan. AKCL also sells its products to the Company
for resale outside of Japan.

The Company's share of the joint venture's net income was $5,457,000, $4,860,000
and $3,172,000 in 1994, 1993 and 1992, respectively. Additionally, the Company
recorded royalty income of $1,786,000 in 1992. Royalty income, included in other
income in the consolidated statements of operations, ceased in 1992 when the
contractual limit was reached.

In 1992 AKCL recorded a positive cumulative effect adjustment of $747,000 as a
result of a change in accounting method due to the adoption of Statement of
Financial Accounting Standard No. 109 (FAS 109) "Accounting for Income Taxes".

NOTE 12.  PARTICIPATION IN HEADWAY TECHNOLOGIES, INC.

   
In September 1994 the Company announced its participation in Headway
Technologies, Inc. ("Headway"), a new company formed to research, develop, and
manufacture advanced magnetoresistive ("MR") heads for the data storage
industry. Hewlett-Packard Company ("HP") and AKCL (see Note 11) provided the
initial cash funding to Headway in exchange for equity interests. The Company
and Asahi America licensed to Headway MR technology developed by Dastek and
contributed certain research and production equipment in exchange for equity. As
a result of these transactions the Company holds a voting interest (direct and
indirect combined) in Headway of less than 20%. The Company has no cost basis in
its investment in Headway; consequently, anticipated initial losses at Headway
will not directly affect the Company's earnings. The Company has not guaranteed
any obligation of Headway and is not otherwise committed to provide financial
support to Headway.
    

AKCL invested in Headway in the third quarter of 1994 and recorded a partial
writedown of its investment in Headway in the fourth quarter of 1994. Headway is
a development stage company and AKCL will continue such writedowns until Headway
emerges from the development stage. These partial writedowns are a function of
losses incurred at Headway. AKCL's net income for 1994 included a writedown of
approximately $480,000, net of tax, of its investment in Headway.

         (b) REPORTS ON FORM 8-K.

         Not Applicable

UNDERTAKING

         For the purposes of complying with the amendments to the rules
governing Form S-8 (effective July 13, 1990) under the Securities Act of 1933,
the undersigned registrant hereby undertakes as follows:

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers or controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
1933 Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such 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 such director, officer or controlling person in
connection with the securities being registered on the Form S-8 identified
below, 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 such indemnification by it is against public
policy as expressed in the 1933 Act and will be governed by the final
adjudication of such issue.

         The preceding undertaking shall be incorporated by reference into
registrant's Registration Statements on Form S-8 Nos. 33-16625 (filed August 19,
1987), 33-19851 (filed January 28, 1988), 33-25230 (filed October 28, 1988),
33-41945 (filed July 29, 1991), 33-45469 (filed February 3, 1992), 33-53432
(filed October 16, 1992) and 33-80594 (filed June 22, 1994).

                        REPORT OF INDEPENDENT ACCOUNTANTS

The Board of Directors and Stockholders
Asahi Komag Co., Ltd.

     We have audited the accompanying balance sheet of Asahi Komag Co., Ltd. as
of December 31, 1994 and 1993, and the related statements of income, cash flows
and stockholders' equity for each of the three years in the period ended
December 31, 1994. 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 did not audit the financial
statements of Headway Technologies, Inc. ("Headway"), the Company's investment
in which, recorded using the cost method, represents eight percent of the
Company's total assets as of December 31, 1994. Those statements were audited by
other auditors whose report has been provided to us and our opinion, insofar as
it relates to the amounts included for Headway, is based solely on the report of
the other auditors.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. These 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, based on our audit and the report of other auditors, the
financial statements referred to above present fairly, in all material respects,
the financial position of Asahi Komag Co., Ltd. as of December 31, 1994 and
1993, and the results of its operations and its cash flows for each of the three
years in the period ended December 31, 1994 in conformity with generally
accepted accounting principles applicable in the United States of America.

     As discussed in Note 2g to the financial statements, the Company changed
its method of accounting for income taxes in 1992.
