EXHIBIT 99.1 PRESS RELEASE S1 CORPORATION ANNOUNCES PRELIMINARY FINANCIAL RESULTS FOR FIRST QUARTER 2003 ATLANTA, April 7 -- S1 Corporation (Nasdaq: SONE - News), a leading global provider of Enterprise solutions for the financial services industry, announced an update to its financial outlook for first quarter 2003. S1 expects its first quarter 2003 loss to be within the range of ($0.11) to ($0.13) per share, as compared with its previously announced expectations for earnings within a range of a loss of ($0.02) per share to a profit of $0.01 per share. The expected loss includes charges of ($0.11) per share resulting from costs associated with restructuring and cost containment measures described below. S1's first quarter 2003 revenue is expected to be $58 million to $60 million, versus its previous revenue guidance of $57 million to $60 million. The company will discuss its expectations for financial results for the full year 2003 during its quarterly earnings conference call scheduled for May 1. "We met our revenue goals for Q1; however we continue to experience an economic environment that elongates sales and implementation cycles," said Jaime Ellertson, S1 Chief Executive Officer. "Our principal focus for 2003 centers on building a long-term stable Enterprise customer base. This focus in combination with the current difficult market conditions leads us to re-evaluate our revenue expectations for the remainder of the 2003 calendar year. We will update our revenue and earnings guidance on our first quarter earnings conference call." A combination or restructuring and other cost containment measures during the first quarter will result in a net impact of ($0.09) per share on first quarter earnings and an expected net impact of $0.02 per share on second quarter earnings. An explanation of the impact of these charges on the company's financial results follows: Q1 2003 Q2 2003 --------------- -------------- (in millions except per share data) Acceleration of contract (1) Revenue from customer contract $1.6 $4.7 Direct costs associated with contract (0.4) (0.4) Net impact of contract acceleration $1.2 $4.3 EPS impact of contract acceleration $0.02 $0.06 Restructuring Expense Costs associated with consolidation of global data center (2) (2.3) (2.5) Loss on excess facilities (3) (2.6) -- Other restructuring charges (4) (2.7) -- Net impact of restructuring charges ($7.6) ($2.5) EPS impact of restructuring ($0.11) ($0.04) Shares used in calculation 69.0 69.0 (1) During the first quarter, S1 amended its contract with a major European customer to shorten the term over which revenue will be recognized and payments received associated with the provision of data center services by S1.
