WINDSOR, CT — May 12, 2010 — SS&C Technologies Holdings, Inc. (Nasdaq: SSNC), a global provider of financial services software and software-enabled services, today announced results for the quarter ended March 31, 2010. Revenue on a GAAP basis for the first quarter of 2010 was $78.2 million. This is an increase of $14.5 million, or 22.7%, from revenues over the same period in 2009. Net income, on a GAAP basis, for the first quarter of 2010, was $9.0 million, an increase of $5.1 million, or 131.4%, over the same period in 2009. Diluted earnings per share for Q1 2010 were $0.14, 133.3% higher than the Q1 2009 $0.06 diluted earnings per share (EPS).

Adjusted revenue, which is adjusted for one-time purchase accounting adjustments (a non-GAAP measure defined in note 1 to the attached Consolidated Condensed Financial Information), was $78.3 million, an increase of $14.5 million or 22.8% from $63.7 million in the same period of 2009.

Adjusted operating income (a non-GAAP financial measure defined in note 2 to the attached Consolidated Condensed Financial Information) was $30.1 million for the three months ended March 31, 2010, compared to $23.9 million in the first quarter of the prior year, an increase of 26.2%. GAAP operating income in the first quarter of 2010 was $19.4 million and includes amortization of $8.7 million and stock-based compensation of $1.4 million, compared to $14.5 million of operating income for the same period in 2009, an increase of 34.2%. Adjusted Consolidated EBITDA (a non-GAAP financial measure defined in note 3 to the Consolidated Condensed Financial Information) for the first quarter of 2010 was $31.6 million, compared to $25.0 million in the first quarter of 2009, an increase of 26.2%.

Adjusted net income and adjusted diluted earnings per share (non-GAAP measures defined in note 4 to the attached Consolidated Condensed Financial Information) was $14.1 million and $0.22 compared to $9.8 million and $0.16 in Q1 2009.

“We are pleased with our first quarter results and our 22.8% increase in adjusted revenues,” said Bill Stone, Chairman and CEO, SS&C Technologies. “We continue to execute on our strategy to grow our software-enabled services revenues, both

organically and from our acquisitions, and in Q1 achieved a 32.3% increase in software-enabled services revenues over the same period last year.”

“Our strong 34% increase in operating income is an indication we are beginning to reap the rewards of our focus over the past 12 months to improve our operating margins,” continued Stone.

Cash Flow

SS&C generated net cash from operating activities of $15.5 million for the three months ended March 31, 2010, compared to $11.0 million for the same period in 2009, representing a 40.9% increase.

“Our balance sheet and cash flow position is strong and the quality of our earnings is high. We generated $15.5 million in net cash from operations during the first quarter,” said Stone. “We continue to focus on paying down debt and in May we will be using a portion of the cash proceeds from the initial public offering of SS&C Technologies Holdings, Inc. to redeem $71,750,000 in aggregate principal amount outstanding of our 11 3/4% Senior Subordinated Notes due 2013.”

Acquisitions

“During the past two quarters, SS&C completed three acquisitions,” said Stone. “In the first quarter, we acquired certain assets of Geller Investment Partnership Services. Geller Investment Partnership Services (GIPS) provides accounting and reporting, performance, tax, administrative and investor services for private equity funds, funds of hedge funds and limited partners that invest in alternatives,” continued Stone. “This transaction favorably positions us, in combination with our existing private equity fund administration business as well as our Q4 2009 acquisition of TheNextRound private equity software, to further establish private equity as a major growth initiative.”

”On December 31, 2009, we acquired New York City based Tradeware Global Corp., a leading broker-neutral solution provider. The acquisition is part of our plan to round out our trading capabilities and we are excited about this strategic fit and future opportunities,” said Stone. “In February of this year, SS&C unveiled Antares Trader™, an integrated buy-side Order and Execution Management System (OEMS). Antares Trader™ is a successful integration of our trade order management system, Antares™, with enhanced execution management capabilities of Tradeware^®,

Outlook

Based on the information available as of May 12, 2010, we currently expect second quarter revenues to be in the range of $80.0 to $81.0 million, and adjusted net income to be in the range of $15.8 to $16.2 million, assuming an effective tax rate of 35% and 74.5 to 75.0 million diluted shares outstanding for the quarter ending June 30, 2010. For full year 2010, our expectation is for revenues to be in the range of $324.0 to $328.0 million and adjusted net income in the range of $62.0 to $63.0 million. We currently expect the number of diluted shares outstanding to increase by approximately 0.5 million per quarter for the third and the fourth quarters of 2010.

Notes to Consolidated Condensed Financial Information

Note 1. Reconciliation of Revenue to Adjusted Revenue

Adjusted revenue represents revenue adjusted for one-time purchase accounting adjustments to fair value deferred revenue acquired in business combinations. Adjusted revenue is presented because we use this measure to evaluate performance of our business against prior periods and believe it is a useful indicator of the underlying performance of the Company. Adjusted revenue is not a recognized term under generally accepted accounting principles (GAAP). Adjusted revenue does not represent revenue, as that term is defined under GAAP, and should not be considered as an alternative to revenue as an indicator of our operating performance. Adjusted revenue as presented herein is not necessarily comparable to similarly titled measures. The following is a reconciliation between adjusted revenue and revenue, the GAAP measure we believe to be most directly comparable to adjusted revenue.

Note 2. Reconciliation of Operating Income to Adjusted Operating Income

Adjusted operating income represents operating income adjusted for amortization of acquisition-related intangible assets and purchase accounting adjustments for deferred revenue and other expenses. Adjusted operating income is presented because we use this measure to evaluate performance of our business and believe it is a useful indicator of the underlying performance of the Company. Adjusted operating income is not a recognized term under GAAP. Adjusted operating income does not represent operating income, as that term is defined under GAAP, and should not be considered as an alternative to operating income as an indicator of our operating performance. Adjusted operating income as presented herein is not necessarily comparable to similarly titled measures. The following is a reconciliation between adjusted operating income and operating income, the GAAP measure we believe to be most directly comparable to adjusted operating income.

Note 3. Reconciliation of Net Income to EBITDA, Consolidated EBITDA and Adjusted Consolidated EBITDA

EBITDA represents net income before interest expense, income taxes, depreciation and amortization. Consolidated EBITDA, defined under our Credit Agreement entered into in November 2005, is used in calculating covenant compliance, and is EBITDA adjusted for certain items. Consolidated EBITDA is calculated by subtracting from or adding to EBITDA items of income or expense described below. Adjusted consolidated EBITDA is calculated by subtracting acquired EBITDA from consolidated EBITDA. EBITDA, consolidated EBITDA and adjusted

consolidated EBITDA are presented because we use these measures to evaluate performance of our business and believe them to be useful indicators of an entity’s debt capacity and its ability to service debt. EBITDA, consolidated EBITDA and adjusted consolidated EBITDA are not recognized terms under GAAP and should not be considered in isolation or as an alternative to operating income, net income or cash flows from operating activities. EBITDA, consolidated EBITDA and adjusted consolidated EBITDA do not represent net income, as that term is defined under GAAP, and should not be considered as an alternative to net income as an indicator of our operating performance. The following is a reconciliation between EBITDA, consolidated EBITDA and adjusted consolidated EBITDA and net income.

Note 4. Reconciliation of Net Income to Adjusted Net Income and Diluted Earnings Per Share to Adjusted Diluted Earnings Per Share

Adjusted net income and adjusted diluted earnings per share represent net income and earnings per share before amortization of intangible assets and deferred financing costs, stock-based compensation, capital-based taxes and other unusual and non-recurring items. Adjusted net income and adjusted diluted earnings per share are not recognized terms under GAAP, do not represent net income or diluted earnings per share, as those terms are defined under GAAP, and should not be considered as alternatives to net income or diluted earnings per share as indicators of our operating performance. Adjusted net income and adjusted diluted earnings per share are important to management and investors because they represent our operational performance exclusive of the effects of amortization of intangible assets and deferred financing costs, stock-based compensation, capital-based taxes and other unusual and non-recurring items that are not operational in nature or comparable to those of our competitors. Adjusted net income and adjusted diluted earnings per share as presented herein are not necessarily comparable to similarly titled measures. The following is a reconciliation between adjusted net income and adjusted diluted earnings per share and net income and diluted earnings per share.
