Highlights:

“SS&C closed out 2016 with over $1.5 billion in adjusted revenues, and adjusted consolidated EBITDA margins above 40 percent” says Bill Stone, Chairman and Chief Executive Officer. “Our year is marked by our acquisitions of Citi Alternative Investor Services, Salentica, Wells Fargo Global Fund Services, and Conifer Financial Services – expanding our reach and capability in fund administration and RIAs. The talent we acquired, both organically and through acquisitions, increase our market opportunity and our ability to win bigger, more complex mandates from top financial institutions.”

Annual Run Rate Basis

Annual Run Rate Basis (ARRB) recurring revenue, defined as adjusted recurring revenue on an annualized basis, was $1,473.8 million based on adjusted recurring revenue $368.5 million for the fourth quarter of 2016. This represents an increase of 24.9 percent from $295.0 million and $1,180.0 million run-rate in the same period in 2015 and an increase of 2.3 percent from $360.3 million for the third quarter of 2016, an annual run rate of $1,441.3 million. We believe ARRB of our recurring revenue is a good indicator of visibility into future revenue.

Operating Cash Flow

SS&C ended the year with $117.6 million in cash, and $2,559.6 million in gross debt for a net debt balance of $2,442.0 million. Net cash from operating activities was $181.4 million in Q4 2016, a 64.8 percent increase from $110.1 million in Q4 2015.

Notes to Condensed Consolidated Financial Information

Note 1. Reconciliation of Revenues to Adjusted Revenues

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

The following is a breakdown of recurring and non-recurring revenues and adjusted recurring and non-recurring revenues.

Note 2. Reconciliation of Operating Income to Adjusted Operating Income

Adjusted operating income represents operating income adjusted for amortization of acquisition-related intangible assets, stock-based compensation, 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 July 2016, 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, other unusual and non-recurring items, purchase accounting adjustments, and loss on extinguishment of debt 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.
