WINDSOR, CT, October 29, 2014 (GLOBE NEWSWIRE) – SS&C Technologies Holdings, Inc. (NASDAQ: SSNC), a global provider of investment and financial software-enabled services and software, today announced its financial results for the quarter that ended September 30, 2014.

Financial Highlights:

“SS&C continues to perform and during Q3 we closed two large and complex fund administration deals – a testament to the dedication and persistence of our team. We continue to see momentum in Q4 and have already sold services to two of the world’s largest asset managers this quarter, with significant cross-sell and up-sell potential” said Bill Stone, Chairman and CEO of SS&C Technologies. “We are building a considerable number of new software systems including: regulatory compliance, investor communications, REIT processing and powerful new features and functions in our portal and mobile applications. SS&C is aggressively hiring talented new employees at all levels and we are relentlessly focused on client satisfaction.”

Results

SS&C reported GAAP revenue of $192.6 million for the third quarter of 2014, compared to $179.5 million in the third quarter of 2013, a 7.3 percent increase. GAAP operating income for the third quarter of 2014 was $54.4 million, or 28.2 percent of revenue. This represents an increase of 13.6 percent compared to $47.9 million, or 26.7 percent of revenue, in the third quarter of 2013. GAAP net income for the third quarter of 2014 was $40.8 million compared to $43.5 million in the third quarter of 2013, a 6.1 percent decrease. On a fully diluted GAAP basis, earnings per share in the third quarter of 2014 were $0.47.

Adjusted operating income (a non-GAAP measure defined in note 2 to the attached Condensed Consolidated Financial Information) in the third quarter of 2014 was $78.6 million, or 40.8 percent of revenue. This represents a 10.5 percent increase compared to $71.1 million, or 39.6 percent of revenue, in the third quarter of 2013. Adjusted net income (a non-GAAP measure defined in note 4 to the attached Condensed Consolidated Financial Information) for the third quarter of 2014 was $53.3 million compared to $44.5 million in 2013’s third quarter, a 19.8 percent increase. Adjusted diluted earnings per share (a non-GAAP measure defined in note 4 to the attached Condensed Consolidated Financial Information) in the third quarter of 2014 were $0.61 compared to $0.52 in the third quarter of 2013, a 17.3 percent increase.

Operating Cash Flow

SS&C generated net cash from operating activities of $164.3 million for the nine months ended September 30, 2014, compared to $154.3 million for the same period in 2013, representing a 6.5 percent increase. SS&C ended the quarter with $75.1 million in cash, and $608.0 million in gross debt, for a net debt balance of $532.9 million. SS&C’s leverage ratio as defined in our credit agreement stood at 1.71 times consolidated EBITDA as of September 30, 2014.

Annual Run Rate Basis

Annual Run Rate Basis (ARRB) recurring revenue, defined as the sum of maintenance and software-enabled services revenue for the quarter on an annualized basis, was $699.5 million based on maintenance and software-enabled services revenue of $174.9 million for the third quarter of 2014. This represents an increase of 6.4 percent from $164.3 million and $657.2 million annual run-rate in the same period in 2013 and an increase of 2.1 percent from $171.2 million for the second quarter of 2014, an annual run rate of $685.0 million. We believe ARRB of our recurring revenue is a good indicator of visibility into future revenue.

Notes to Condensed Consolidated 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 March 2012, 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 alternatives to operating income, net income or cash flows from operating activities as indicators of our operating performance. The following is a reconciliation of EBITDA, consolidated EBITDA and adjusted consolidated EBITDA to 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. The following is a reconciliation between adjusted net income and adjusted diluted earnings per share and net income and diluted earnings per share.
