Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Principles of Consolidation	Note 1—Basis of Presentation and Principles of Consolidation The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). These accounting principles were applied on a basis consistent with those of the audited Consolidated Financial Statements contained in our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the Securities and Exchange Commission (the “SEC”) on February 28, 2024 (the “2023 Form 10-K”). In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements contain all adjustments (consisting of only normal recurring adjustments, except as noted elsewhere in the notes to the Condensed Consolidated Financial Statements) necessary for a fair statement of our financial position as of March 31, 2024, the results of our operations for the three months ended March 31, 2024 and 2023, and our cash flows for the three months ended March 31, 2024 and 2023. These statements do not include all of the information and footnotes required by GAAP for annual financial statements. The Condensed Consolidated Financial Statements contained herein should be read in conjunction with the audited Consolidated Financial Statements and footnotes as of and for the year ended December 31, 2023, which were included in the 2023 Form 10-K. The December 31, 2023 Consolidated Balance Sheet data were derived from audited financial statements but do not include all disclosures required by GAAP for annual financial statements. The results of operations for the three months ended March 31, 2024 are not necessarily indicative of the expected results for any subsequent quarters or the full year. The accompanying unaudited condensed consolidated financial statements include the accounts of SS&C Technologies Holdings, Inc. and its subsidiaries, including a variable interest entity (“VIE”) for which we are the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. Recent Accounting Pronouncements Not Yet Effective In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The standard is applicable to all public entities, including public entities with a single reportable segment, and requires enhanced reportable segment disclosures. The disclosures include significant segment expenses regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss. The standard also requires disclosure of the title and position of the CODM as well as how the CODM uses the reported measures of a segment’s profit or loss to assess segment performance and decide how to allocate resources. The new standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 31, 2024. Early adoption is permitted. We are currently evaluating the potential impact the standard will have on our disclosures. In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures (Topic 740) . The standard requires more enhanced disclosures specifically related to effective tax rate reconciliation and income taxes paid. The new requirements will be effective for fiscal years beginning after December 15, 2024, on a prospective basis. Early adoption and retrospective application are permitted. We are currently evaluating the potential impact the standard will have on our income tax disclosures.

Unrealized gains for our equity securities are as follows (in millions): Three Months Ended March 31, 2024 2023 Unrealized gains on equity securities held as of the end of the period $ 0.9 $ 2.3 Fair Value Measurement Authoritative accounting guidance on fair value measurements establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs for which little or no market data exists, therefore requiring an entity to develop its own assumptions. As of March 31, 2024 and December 31, 2023, we held certain investment assets and certain liabilities that are required to be measured at fair value on a recurring basis. These investments include money market funds and marketable equity securities where fair value is determined using quoted prices in active markets. Accordingly, the fair value measurements of these investments have been classified as Level 1 in the tables below. Investments for which we elected net asset value as a practical expedient for fair value and investments measured using the fair value measurement alternative are excluded from the tables below. Fair value for deferred compensation liabilities that are credited with deemed gains or losses of the underlying hypothetical investments, primarily equity securities, have been classified as Level 1 in the tables below. The following tables present assets and liabilities measured at fair value on a recurring basis (in millions): Fair Value Measurements at Reporting Date Using March 31, 2024 Quoted prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Money market funds (1) $ 1,781.6 $ 1,781.6 $ — $ — Seed capital investments (2) 26.3 26.3 — — Marketable equity securities (2) 22.5 22.5 — — Deferred compensation liabilities (3) ( 12.3 ) ( 12.3 ) — — Total $ 1,818.1 $ 1,818.1 $ — $ — Fair Value Measurements at Reporting Date Using December 31, 2023 Quoted prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Money market funds (1) $ 2,212.6 $ 2,212.6 $ — $ — Seed capital investments (2) 26.1 26.1 — — Marketable equity securities (2) 23.1 23.1 — — Deferred compensation liabilities (3) ( 11.7 ) ( 11.7 ) — — Total $ 2,250.1 $ 2,250.1 $ — $ — (1) As of March 31, 2024 , included $ 112.3 million of cash and cash equivalents, $ 1.6 million of restricted cash and $ 1,667.7 million of funds receivable and funds held on behalf of clients on the Condensed Consolidated Balance Sheet.

(2) Included in Investments on the Condensed Consolidated Balance Sheet . (3) Included in Other long-term liabilities on the Condensed Consolidated Balance Sheet . We have partnership interests in various private equity funds that are not included in the tables above. Our inve stments in private equity funds were $ 10.9 million and $ 11.5 million at March 31, 2024 and December 31, 2023 , respectively, of which $ 9.3 million and $ 9.2 million, respectively, were measured using net asset value as a practical expedient for fair value and $ 1.6 m illion and $ 2.3 million, respectively, were accounted for under the equity method of accounting. The investments in private equity funds represent underlying investments in domestic and international markets across various industry sectors. Generally, our investments in private equity funds are non-transferable or are subject to long holding periods, and withdrawals from the private equity firm partnerships are typically not permitted. The maximum risk of loss related to our private equity fund investments is limited to the carrying value of its investments in the entities.

Revenue from Contract with Customer [Abstract]
Revenues	Note 9—Revenues We generate revenues primarily through our software-enabled services. Our software-enabled services are generally provided under contracts with initial terms of one to five years that require monthly or quarterly payments and are subject to automatic annual renewal at the end of the initial term unless terminated by either party. We also generate revenues by licensing our software to clients through either perpetual or term licenses and by selling maintenance services. We classify license revenues related to sales-based royalty arrangements as term license revenue. Maintenance services are generally provided under annually renewable contracts. Our pricing typically scales as a function of our clients’ assets under management, the complexity of asset classes managed, the volume of transactions and the level of service the client requires. Revenues from professional services consist mostly of services provided on a time and materials basis. Deferred revenues primarily represent unrecognized fees billed or collected for maintenance and professional services. Deferred revenues are recognized as (or when) we perform under the contract. Deferred revenues are recorded on a net basis with contract assets at the contract level. Accordingly, as of March 31, 2024 and December 31, 2023 , approximately $68.5 million and $ 72.0 million, respectively, of deferred revenue is presented net within contract assets arising from the same con tracts. The amount of revenues recognized in the period that was included in the opening deferred revenues balance was $158.2 million for the three months ended March 31, 2024. As of March 31, 2024, revenue of approximately $1,005.2 million is expected to be recognized from remaining performance obligations for license, maintenance and related revenues, of which $496.2 million is expected to be recognized over the next twelve months. We record revenue net of any taxes assessed by governmental authorities.
