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 of these statements in accordance with auditing standards generally accepted in the United States of America, which require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of assets held for investment purposes and reportable transactions 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/ PricewaterhouseCoopers LLP Atlanta, Georgia June 8, 2001 3 S1 CORPORATION 401(K) SAVINGS PLAN STATEMENTS OF NET ASSETS AVAILABLE FOR BENEFITS DECEMBER 31, 2000 1999 ASSETS Investments $21,455,293 $21,294,853 Restricted S1 Corporation common stock 758,332 -- ----------- ----------- Total investments 22,213,625 21,294,853 ----------- ----------- Receivables Participant contributions 202,479 86,260 Employer contributions 92,512 23,288 ----------- ----------- Total receivables 294,991 109,548 ----------- ----------- Net assets available for benefits $22,508,616 $21,404,401 =========== =========== The accompanying notes are an integral part of these financial statements. 2 4 S1 CORPORATION 401(K) SAVINGS PLAN STATEMENT OF CHANGES IN NET ASSETS AVAILABLE FOR BENEFITS FOR THE YEAR ENDED DECEMBER 31, 2000 Additions to net assets attributed to Interest and dividends $ 1,623,083 ------------ Contributions Participant 6,412,819 Employer 2,878,174 Rollovers from other plans 1,598,569 ------------ Total contributions 10,889,562 ------------ Total additions 12,512,645 ------------ Deductions from net assets attributed to Net depreciation in fair value of investments (22,301,520) Benefits paid to participants (3,440,309) ------------ Total deductions (25,741,829) ------------ Net decrease in net assets available for benefits before transfers from merged plans (13,229,184) Transfers of net assets available for plan benefits from merged plans 14,333,399 ------------ Net increase in net assets available for benefits 1,104,215 Net assets available for benefits Beginning of period 21,404,401 ------------ End of period $ 22,508,616 ============ The accompanying notes are an integral part of these financial statements. 3 5 S1 CORPORATION 401(K) SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS 1. DESCRIPTION OF THE PLAN The following description of the S1 Corporation 401(k) Savings Plan (the "Plan") provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions. GENERAL The Plan, which commenced on July 1, 1996, is a defined contribution plan covering all eligible employees of S1 Corporation (the "Company"). Employees are eligible to participate immediately upon hire. Enrollment in the Plan occurs as soon as administratively feasible. The Plan is subject to certain provisions of the Employee Retirement Income Security Act of 1974 (ERISA), as amended. AMENDMENTS The Company changed its name from Security First Technologies, Inc. to S1 Corporation in November 1999. During January 2000, the Plan was amended to change its name from the Security First Technologies, Inc. 401(k) Savings Plan to the S1 Corporation 401(k) Savings Plan. Also in January 2000, the custodian and recordkeeper was changed from Principal Life Insurance Company ("Principal") to T. Rowe Price Trust Company ("T. Rowe Price"). All net assets previously held by Principal were transferred into T. Rowe Price funds in January 2000. CONTRIBUTIONS Participants may contribute from 1% to 15% of their pretax earnings, up to a maximum of $10,500 in 2000 and $10,000 in 1999. Rollover contributions from other qualified plans are permitted. Effective January 2000, the Company makes matching contributions of $1.00 for every dollar that participants elect to contribute, up to a defined limit. Employer contributions are limited to the first 4% of the employee's eligible compensation and are made in the form of S1 Corporation common stock. Participants are restricted from transferring employer contributions until 12 calendar months following the date the contribution was made. During 1999, the Company made matching contributions of $.25 for every dollar that participants elected to contribute to investments other than the S1 Corporation Common Stock Fund and $1.00 for every dollar that participants elected to contribute to the S1 Corporation Common Stock Fund, up to a defined limit. Employer contributions were limited to the first 4% of the employee's eligible compensation. ROLLOVERS FROM OTHER PLANS Transfers of account balances from other qualified retirement plans by newly employed participants are presented as "rollovers from other plans" in the Statement of Changes in Net Assets Available for Benefits. PARTICIPANT ACCOUNTS All contributions made to the selected investment funds are participant directed with the exception of employer matching contributions made to S1 Corporation common stock. Each participant's account is credited with the participant's contribution and allocations of (a) the Company's contribution and (b) Plan earnings. Allocations are based on participant 4 6 S1 CORPORATION 401(K) SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant's vested account. INVESTMENTS The Plan's assets are invested in mutual funds and S1 Corporation common stock. Participants may change their investment allocation, as well as elections on future investments, at any time. Investment transfers from the S1 Corporation Common Stock Fund are subject to certain restrictions, as defined in the Plan agreement. The Plan allocates earnings to participants based on the ratio of the participant's account balance in each investment fund to the total of all participants' account balances in each investment fund. Earnings allocations to participant accounts occur at various intervals throughout the year and depend on which funds the participant has invested. For a description of the Plan's investment options, participants should refer to the Plan document and each fund's most current prospectus. VESTING Participants vest immediately in their contributions plus earnings thereon. Retroactively effective January 1, 2000, Company contributions plus earnings thereon vest at a rate of 25% per year starting with the first year of participation. Participants become fully vested in Company contributions upon reaching normal retirement age, total and permanent disability, or death. Prior to January 1, 2000, employees vested in their Company contributions at a rate of 33-1/3% per year starting with the third year of participation. As discussed in Note 4, the net assets of the Edify Corporation employee retirement plan were merged into the Plan during January 2000. Employees of Edify Corporation hired prior to January 1, 2000, will follow the vesting schedule of the Edify Corporation 401(k) Profit Sharing Plan (the "Edify Plan") for all balances transferred, together with earnings thereon, from the Edify Plan. The Edify Plan vests ratably over three years beginning with the first year of participation. DISTRIBUTION OF BENEFITS Participants who separate from service for any reason other than retirement and whose value of all vested accounts is $5,000 or less may have the value of their vested contributions distributed to them in a lump sum or elect a rollover distribution. If the vested account balance is greater than $5,000, the participant may elect to receive a lump sum distribution, make a rollover distribution or delay receiving the distribution until normal retirement age. Distribution of benefits to retired participants can be made in either lump sum or periodic payments. If participants die before receiving distribution of their accounts, the full amount of their accounts will be paid to their designated beneficiaries. As discussed in Note 4, the net assets of the Edify Corporation employee retirement plan were merged into the Plan during January 2000. Former Edify Corporation employees who have account balances as of December 31, 1999, are subject to special provisions. If the participant was married on the date benefits are to begin, the participant will automatically receive a joint and survivor annuity, unless he elects otherwise. If the participant was single on the date elections are to begin, the participant will receive a single life annuity, unless he elects otherwise. Participants may make a written election to waive the annuity form of payment during the 90-day period before the annuity is to begin. 5 7 S1 CORPORATION 401(K) SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS PARTICIPANT LOANS Beginning in January 2000, participants are allowed to borrow from their vested account balances. Participants may borrow at a minimum $1,000 and at a maximum the lesser of (a) $50,000 reduced by the participants' highest outstanding Plan loan balances during the 12 months preceding the date of the loan or (b) one-half the value of the participants' vested interests in their accounts. Interest on the loans is 1% over the prime rate on the first business day of the calendar quarter immediately preceding the date as of which the loan is issued. Participants may have only one loan outstanding at any time. FORFEITURES Participants forfeit the nonvested portion of the employer matching contributions upon the earlier of (a) the distribution of the vested portion of their accounts, or (b) when the participant incurs five consecutive years with a break in service. Forfeitures are used by the Company to pay administrative expenses. Forfeitures not used to pay expenses shall be applied to reduce the earliest employer contributions made after the forfeitures are determined. Forfeitures amounted to $147,000 and $166,000 in 2000 and 1999, respectively. ADMINISTRATIVE EXPENSES Administrative expenses in excess of forfeitures are paid by the Company. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION The accompanying financial statements have been prepared on the modified accrual basis. INVESTMENTS Investments are stated at fair value. Shares of registered investment companies are valued at quoted market prices, which represent the net asset value of shares held by the Plan at year-end. The Company's stock is valued at its quoted market price. Purchases and sales of investments are recorded on a trade-date basis. Net depreciation in fair value of investments, including realized gains and losses, represents the change in fair value during the year and realized gains and losses on investments sold or distributed during the year. CONTRIBUTIONS Employee and employer contributions are generally recorded in the period after the Company makes payroll deductions from the participants' earnings. At period end, receivables are recorded to reflect contributions made but not yet received. USE OF ESTIMATES The preparation of the 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 disclosures of contingent assets and liabilities. Actual results could differ from those estimates. 6 8 S1 CORPORATION 401(K) SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS PAYMENT OF BENEFITS Benefits are recorded when paid. RISKS AND UNCERTAINTIES The Plan's investments are subject to market risk due to changes in securities prices. In particular, the Plan's investments in S1 Corporation common stock are exposed to significant market risk due to the high volatility of the Company's common stock price. At December 31, 2000 and 1999, the Plan has a significant investment balance in S1 Corporation common stock. Depending on the Company's common stock price, the Plan could experience significant fluctuations in asset values due to market volatility. 3. INVESTMENTS The following table presents investments that represent 5 percent or more of the Plan's net assets: DECEMBER 31, 2000 1999 ------------ ------------ Janus Fund $ 1,272,478 $ -- T. Rowe Price Value Fund 1,466,656 -- T. Rowe Price Equity Index 500 Fund 2,534,198 -- T. Rowe Price Science & Technology Fund 2,876,563 -- T. Rowe Price Mid-Cap Growth Fund 1,978,682 -- T.

Rowe Price Blue Chip Growth Fund 2,645,091 -- S1 Corporation Common Stock 2,210,007 17,850,623 The S1 Corporation Common Stock balance includes amounts contributed based on participant elections and employer matching contributions. As discussed in Note 1, employer matching contributions are restricted for a period of 12 calendar months from the date of contribution. 4. PLAN MERGERS In November 1999, the Company completed the acquisitions of Edify Corporation ("Edify"), FICS Group, N.V. ("FICS") and VerticalOne Corporation ("VerticalOne"). In April 2000, the Company completed the acquisitions of Q-Up Systems, Inc. ("Q-Up") and Davidge Data Systems Corporation ("Davidge"). In November 2000, the Company completed the acquisition of LevelNext, Inc. ("LevelNext"). The employee retirement plans of Q-Up, Davidge and LevelNext were terminated and participants were given the option to enroll in the Plan upon acquisition. The assets of Edify's, FICS' (domestic operations only) and VerticalOne's employee retirement plans were merged into the Plan in January 2000. As a result of the Plan mergers, the number of participants increased from approximately 600 at December 31, 1999 to approximately 1,600 at December 31, 2000. The following table presents the value of plan net assets transferred into the Plan from the respective acquired company's plan: 7 9 S1 CORPORATION 401(K) SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS Edify $12,313,768 FICS 1,801,214 VerticalOne 218,417 Generally, the participants in these plans are given full credit for their service with their previous employers for purposes of both eligibility and vesting in the Plan. 5. 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. In the event of plan termination, participants will become 100 percent vested in their accounts. 6. TAX STATUS The Internal Revenue Service has determined and informed the Company by a letter dated August 2, 1999, that the Plan and related trust are designed in accordance with applicable sections of the Internal Revenue Code (IRC). Although the Plan has been amended since receiving the determination letter, 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. RELATED PARTY TRANSACTIONS At December 31, 2000 and 1999, the Plan holds 420,954 and 228,488 shares of S1 Corporation common stock with a market value of $2,210,007 and $17,850,623, respectively. In January 2000, the custodian and recordkeeper changed to T. Rowe Price. Certain Plan investments are shares of mutual funds managed by T. Rowe Price and therefore, these transactions qualify as party-in-interest transactions. During 1999, certain Plan investments were shares of mutual funds managed by Principal. Principal was the custodian and the recordkeeper of the Plan during 1999 and, therefore, these transactions qualify as party-in-interest transactions. Fees incurred for administrative expenses amounted to approximately $20,000 and $62,000 for the years ended December 31, 2000 and 1999, respectively. 8. SUBSEQUENT EVENT On January 18, 2001, the Company sold VerticalOne, a wholly-owned subsidiary of the Company, to Yodlee.com, Inc. As a result, all individuals who were employees of VerticalOne and were Plan participants were severed from Plan participation effective January 18, 2001. The Plan net assets attributable to the employees of VerticalOne will be transferred out of the Plan in accordance with the terms of the sale agreement. 8 10 S1 CORPORATION 401(K) SAVINGS PLAN SCHEDULE H, LINE 4I - SCHEDULE OF ASSETS HELD FOR INVESTMENT PURPOSES DECEMBER 31, 2000 DESCRIPTION OF CURRENT IDENTITY OF ISSUE INVESTMENT SHARES COST VALUE - ----------------- ------------------- ------- ---------- ----------- Participant Loans - Interest rates of 7.5% to 10.5% Participant Loans N/A $ -- $ 252,636 Janus Fund Mutual Fund 38,224 1,676,498 1,272,478 * T.
