Workday shares rose 18% Thursday to close near $270, adding $7.8 billion in market capitalization after Bloomberg reported Silver Lake Partners held preliminary acquisition discussions with the human-capital-management software provider. The move puts Workday's enterprise value near $51 billion including net debt, a figure that would eclipse Vista Equity's $16.5 billion take-private of Citrix Systems in September 2022 and mark the largest enterprise-software LBO on record.

Silver Lake, which holds a $103 billion portfolio including stakes in Endeavor Group and Qualtrics, has not made a formal offer. Workday's board has not retained advisors. The company trades at 5.2x forward revenue, a 38% discount to its five-year average multiple of 8.4x, despite posting 17% subscription-revenue growth in the January quarter and guiding to 16% growth for fiscal 2027. The discount reflects broader SaaS repricing since the Federal Reserve began tightening in March 2022, when Workday traded above $310 per share. The stock bottomed at $156 in October 2023.

A deal at this scale tests three structural questions allocators have watched since Thoma Bravo abandoned its $10.7 billion Anaplan acquisition in June 2022. First, whether large-cap private equity can syndicate $35 billion to $40 billion in debt for a software asset in a market where leveraged-loan appetite remains selective. Second, whether Silver Lake can credibly model 200 to 300 basis points of EBITDA-margin expansion from a business already running at 24% operating margin, the efficiency level that historically justifies software LBO premiums. Third, whether Workday's 42% renewal rate among Fortune 500 customers and 96% gross retention provide the revenue durability to service eight-figure annual interest expense without growth deceleration.

Operators and allocators should monitor three follow-on events. Workday reports fiscal Q1 earnings on May 22, where management will face questions on the $1.2 billion remaining performance obligation growth rate and any commentary on strategic alternatives. Silver Lake's syndication capacity will become visible if a consortium structure emerges within 30 to 45 days, likely including co-investors such as KKR, Thoma Bravo, or sovereign wealth capital. Finally, watch whether Oracle or SAP, Workday's primary HCM competitors, surface as strategic counter-bidders, a low-probability outcome given both companies' cloud-infrastructure priorities but one that would reset SaaS M&A pricing across the sector.

The $7.8 billion single-day value creation sits inside a $490 billion net capital overhang across the 20 largest buyout funds raised since 2021, capital that has rotated toward infrastructure and credit as software multiples compressed. A signed Workday deal would reopen the large-cap software LBO market that has been functionally closed since the Citrix transaction 31 months ago.
