Box 7108 401 N. 31st Street Billings, MT 59103 INDEPENDENT AUDITORS' REPORT To the Administrator of the Stillwater Mining Company 401(k) Plan and Trust: We have audited the accompanying statements of net assets available for benefits of Stillwater Mining Company 401(k) Plan and Trust (the "Plan") as of December 31, 2001 and 2000 and the related statement of changes in net assets available for benefits for the year ended December 31, 2001. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2001 and 2000, and the changes in net assets available for benefits for the year ended December 31, 2001 in conformity with accounting principles generally accepted in the United States of America. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of Schedule H, line 4i -- schedule of assets (held at end of year) as of December 31, 2001 and Schedule G, Part III -- schedule of nonexempt transactions for the year ended December 31, 2001 are presented for the purpose of additional analysis and are not a required part of the basic financial statements but are supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. These supplemental schedules are the responsibility of the Plan's management. The supplemental schedules have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole. /s/ KPMG LLP Billings, Montana July 23, 2002 STILLWATER MINING COMPANY 401(K) PLAN AND TRUST Statements of Net Assets Available for Benefits December 31, 2001 and 2000 <Table> <Caption> 2001 2000 ------------ ------------ Assets: Cash $ -- 106,885 Investments, at fair value (note 3): Common stock 993,374 1,617,366 Mutual funds 12,968,335 12,399,686 Common/collective trust fund 371,128 -- Participant loans 472,662 460,283 ------------ ------------ Total investments 14,805,499 14,477,335 Receivables: Employer contributions 57,528 37,582 Participant contributions and loan repayments 83,729 58,336 ------------ ------------ Total receivables 141,257 95,918 ------------ ------------ Net assets available for benefits $ 14,946,756 14,680,138 ============ ============ </Table> See accompanying notes to financial statements.

STILLWATER MINING COMPANY 401(K) PLAN AND TRUST Notes to Financial Statements December 31, 2001 and 2000 (1) DESCRIPTION OF THE PLAN On June 1, 1993, Stillwater Mining Company (the "Company") established the Stillwater Mining Company 401(k) Plan and Trust (the "Plan"). The following description of the Plan provides general information only. Participants should refer to the Plan document for a more complete description of the Plan's provisions. (a) GENERAL The Plan is a defined contribution plan covering all non-union employees of the Company, as defined in the Plan document, and is subject to the provisions of the Employee Retirement Income Security Act ("ERISA"). Employees are eligible to participate in the Plan at the beginning of the month following the employee's date of hire. (b) PLAN AND TRUST ADMINISTRATION The administration of the Plan is the responsibility of the Company. The assets of the Plan are maintained in a trust fund that is administered under a trust agreement with Smith Barney Corporate Trust Company (the "Trustee"). (c) CONTRIBUTIONS Each participant has the option to make pre-tax "elective deferral contributions" to the Plan of not less than 1% nor more than 10% of eligible compensation as defined by the Plan agreement. The Company contributes an amount equal to 200% of each participant's elective deferral contribution, up to 3% of the participant's compensation for the contribution period. Each participant also has the option to make after-tax contributions to the Plan of not less than 1% nor more than 10% of eligible compensation. The Company may make annual discretionary profit sharing contributions during each Plan year. Profit sharing contributions will be allocated to participants based on the ratio of each participant's eligible compensation to the total compensation paid to all eligible participants for the Plan year. There were no discretionary contributions during the year ended December 31, 2001. Participant rollovers include transfers of $436,792 from the Stillwater Mining Company Bargaining Unit 401(k) Plan and Trust for the year ended December 31, 2001. (d) PARTICIPANT ACCOUNTS Each participant's account is credited with the participant's contribution and allocation of (a) the Company's matching contribution, (b) Plan earnings and losses, and (c) discretionary contributions by the Company. Allocations of Plan earnings and losses are based on individual participant account balances in relation to the total of all participant account balances. (e) VESTING Participants are at all times fully vested in their voluntary contributions plus actual earnings thereon. Vesting in employer contributions is based on years of continuous service. Participants become 100% vested after three years of service. 1 (continued) STILLWATER MINING COMPANY 401(K) PLAN AND TRUST Notes to Financial Statements December 31, 2001 and 2000 (f) PARTICIPANT LOANS Participant loans shall not exceed the lesser of: (a) $50,000 reduced by the excess of the highest outstanding balance of loans during the one year period ending on the day before the loan is made, over the outstanding balance of loans from the Plan on the date the loan is made; or (b) 50% of the participant's vested balance. Participant loans bear an interest rate comparable to the rate charged by commercial lenders in the geographical area for similar loans. All participant loans must be repaid within five years, unless the loan is utilized by the participant for the purchase of a principal residence, in which case the term of the loan must be repaid over a reasonable period of time, not to exceed ten years. Interest rates on the participant loans outstanding at December 31, 2001 ranged from 6.75% to 10.0%. (g) PAYMENT OF BENEFITS Upon termination, retirement or death, participants or their beneficiaries may elect to receive an amount equal to the vested value of his or her account in either a lump-sum amount or in installments determined by the participant or their beneficiary. Distributions and withdrawals include $80,573 of transfers to the Stillwater Mining Company Bargaining Unit 401(k) Plan and Trust for the year ended December 31, 2001. (h) FORFEITURES Forfeitures of terminated participants' nonvested accounts are retained in the Plan and used first to pay administrative expenses and then to reduce future employer matching contributions. At December 31, 2001 and 2000, forfeited nonvested accounts totaled $23,766 and $35,934, respectively. During 2001 and 2000, $34,250 and $27,160, respectively, of employer matching contributions were forfeited by employees who terminated before those amounts became vested. The amount of forfeitures used to pay administrative expenses in 2001 totaled $47,303. (2) SUMMARY OF ACCOUNTING POLICIES (a) BASIS OF ACCOUNTING The Plan's financial statements are prepared on the accrual basis of accounting. (b) APPRECIATION (DEPRECIATION) OF INVESTMENTS The Plan presents in the statement of changes in net assets the net appreciation (depreciation) in the fair value of its investments, which consists of the realized gains (losses) and the unrealized appreciation (depreciation) of those investments. (c) USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates. 2 (continued) STILLWATER MINING COMPANY 401(K) PLAN AND TRUST Notes to Financial Statements December 31, 2001 and 2000 (d) RISKS AND UNCERTAINTIES The Plan may invest in various types of investment securities. Investment securities are exposed to various risks, such as interest rate, market, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect the amounts reported in the statement of net assets available for plan benefits. (e) INVESTMENT VALUATION AND INCOME RECOGNITION Plan investments are valued at fair value based on the market value or share price at the end of the year. Purchases and sales of investments are recorded on the trade date. Dividends are recorded as of the ex-dividend date. Interest income is recorded on the accrual basis. Participant loans are valued at principal amount, which approximates fair value. The carrying amounts approximate fair value because of the short maturity of those instruments and the rates of interest associated with payments under the agreements approximate the current borrowing rates available to participants for agreements with similar characteristics. Interest income is recorded on the accrual basis. (f) CASH As of December 31, 2000, the Plan had cash which was restricted for the purchase of common stock. (g) EXPENSES OF THE PLAN The Company may reimburse expenses incurred in the administration of the Plan at its discretion. Substantially all expenses are paid by the Company. (h) PAYMENT OF BENEFITS Benefits are recorded when paid. 3 (continued) STILLWATER MINING COMPANY 401(K) PLAN AND TRUST Notes to Financial Statements December 31, 2001 and 2000 (3) INVESTMENTS The following table presents the fair values of investments that represent 5 percent or more of the Plan's net assets as determined by quoted market prices as of December 31: <Table> <Caption> 2001 2000 --------------------------- --------------------------- NUMBER OF NUMBER OF SHARES, UNITS SHARES, UNITS OR LOANS FAIR VALUE OR LOANS FAIR VALUE ------------- ----------- ------------- ----------- Stillwater Mining Company Stock -- Common Stock 53,695 $ 993,374 41,102 $ 1,617,366 Mutual Funds: Janus Fund 69,582 1,713,488 69,054 2,298,799 Dreyfus Premier Core Value Fund 56,919 1,629,750 40,120 1,240,900 Dreyfus Appreciation Fund 34,010 1,293,202 32,791 1,408,047 Janus Twenty Fund 25,823 1,000,303 -- -- Scudder International Fund 25,523 936,450 21,133 1,063,221 Smith Barney Government Portfolio 910,623 910,623 740,594 740,594 Royce Premier 81,889 863,238 55,045 541,089 Janus Enterprise Fund 25,840 828,665 23,819 1,268,839 10,169,093 10,178,855 Other investments less than 5% of the Plan's net assets Participant loans 71 472,662 46 460,283 Other 4,163,744 3,838,197 $ 14,805,499 $ 14,477,335 ============ ============ </Table> During 2001, the Plan's investments (including gains and losses on investments bought and sold, as well as held during the year) depreciated in value by $3,112,417 as follows: <Table> Common Stock $ 1,032,250 Mutual Funds 2,080,167 ------------- $ 3,112,417 ============= </Table> (4) PLAN TERMINATION Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. However, no such action may deprive any participant or beneficiary under the Plan of any vested right. (5) RELATED PARTY TRANSACTIONS Certain Plan investments are shares of mutual funds managed by subsidiaries of Citigroup Inc. Smith Barney Corporate Trust Company, the trustee as defined by the Plan, is also a subsidiary of Citigroup Inc. and, therefore, these transactions qualify as party-in-interest transactions. Administrative fees paid by the Plan to CitiStreet Associates, LLC, the recordkeeper, amounted to $50,653 for the year ended December 31, 2001. 4 (continued) STILLWATER MINING COMPANY 401(K) PLAN AND TRUST Notes to Financial Statements December 31, 2001 and 2000 (6) TAX STATUS The Internal Revenue Service has determined and informed the Company by letter dated May 18, 1995 that the Plan and related trust are designed in accordance with applicable sections of the Internal Revenue Code (IRC). The Plan has been amended since receiving the determination letter. However, the Plan administrator and the Plan's tax counsel believe that the Plan is designed and is currently being operated in compliance with the applicable requirements of the IRC. (7) NONEXEMPT TRANSACTIONS There were unintentional delays by the Company in submitting certain 2001 contributions in the aggregate amount of $1,909 to the Trustee due to a computer program error. The Company remitted the contributions and reimbursed the Plan for lost investment income in the amount of $214 in 2002. There was one unintentional delay by the Company in submitting contributions in the amount of $3,795 to the Trustee during 2001 due to employee bonus compensation that was erroneously omitted from 401(k) eligible wages. The Company remitted the contributions and reimbursed the Plan for lost investment income in the amount of $581 in 2002. There were unintentional delays by the Company in submitting certain 2000 contributions in the aggregate amount of $8,759 to the Trustee due to a computer program error. The Company remitted the contributions and reimbursed the Plan for lost investment income in the amount of $2,013 in 2001. There was one unintentional delay by the Company in submitting certain 1999 contributions in the aggregate amount of $70,109 to the Trustee. The Company reimbursed the Plan for lost investment income in the amount of $2,143 in 2001. (8) SUBSEQUENT EVENTS In November 2001, the Company resolved to provide that employer contributions may be made in common stock of the Company, effective January 1, 2002. No stock contributions were made in 2001. Effective January 1, 2002, the Plan was amended to change allowable participant pre-tax "elective deferral contributions" to the plan from "not less than 1% nor more than 10%" of eligible compensation as defined by the Plan agreement to "not less than 1% nor more than 20%." Company contributions were also changed from 200% of each participant's elective deferral contribution, up to 3% of the participant's compensation for the contribution period to 100% of each participant's elective deferral contribution, up to 6% of the participant's compensation for the contribution period. 5 (continued) SCHEDULE 1 STILLWATER MINING COMPANY 401(K) PLAN AND TRUST Schedule H, line 4i - Schedule of Assets (Held at End of Year) December 31, 2001 <Table> <Caption> (a) (b) IDENTITY OF ISSUE, (c) DESCRIPTION OF INVESTMENT INCLUDING BORROWER, LESSOR MATURITY DATE, RATE OF INTEREST, COLLATERAL, (d) NUMBER OF (e) CURRENT OR SIMILAR PARTS' PAR OR MATURITY VALUE UNITS VALUE ------ ---------------------- -------------------------------------------- ------------- ----------- Janus Capital Corp.
