Workday (NASDAQ: WDAY) delivered a fiscal Q2 that beat both top and bottom line estimates. The real signal, however, is in the composition of that beat. Revenue of $2.649B came in 0.5% above the $2.636B consensus, while non-GAAP diluted EPS of $2.75 cleared estimates by $0.14. The headline numbers are solid. The story is the accelerating AI monetization and the margin expansion that accompanied it.
Subscription revenue rose 13.9% year over year to $2.471B, a slight deceleration from the 14.2% growth in Q1 but still ahead of expectations. The more telling metric: over 25% of new annual contract value came from AI. More than 5,500 customers now use at least one of Workday's organic agents, up over 35% from last quarter. This is not a pilot program anymore. AI is becoming a measurable growth engine within the core subscription base.
The margin story is equally important. Non-GAAP operating margin hit 31.1%, expanding 210 basis points year over year and coming in above the 30% threshold management had previously signaled as a target. GAAP operating margin improved to 11.8% from 10.6%, a narrower gain because of the heavy stock-based compensation Workday excludes from its non-GAAP calculation. The $462M in SBC in the quarter alone was more than the entire GAAP operating income. That gap between GAAP and non-GAAP profitability remains a structural feature of the model, not a temporary one.
GAAP diluted EPS of $2.57 included a $1.52 per share tax benefit from an intra-entity transfer of intellectual property rights during an internal legal entity restructuring. Strip that out, and GAAP EPS would have been roughly $1.05, still up from $0.84 a year ago but far below the non-GAAP figure. The $374M deferred tax asset created by this restructuring will reduce future cash taxes, but it's a one-time accounting event, not an operating improvement.
The guidance raise is the strongest signal management could send. Full-year FY2027 subscription revenue guidance was lifted to $9.940B to $9.950B, implying 13% growth at the midpoint. Non-GAAP operating margin guidance was raised to 31.0% from prior levels. This is a deliberate statement: Workday believes it can sustain both mid-teens growth and expanding margins simultaneously. The Q3 subscription revenue guidance of $2.515B, representing 12% growth, suggests a slight sequential deceleration, but the full-year raise implies confidence in the back half.
The $4.0B share repurchase authorization and the $1.3B in buybacks executed during the quarter are notable. Workday repurchased roughly 9.8 million shares at an average price of about $133, using a combination of cash and debt. The company's cash and marketable securities stood at $3.4B at quarter end, down from $5.4B at the start of the fiscal year, as the buyback program consumed $2.9B in the first half. The balance sheet still carries $3.0B in debt, but net cash remains positive. The buyback pace looks aggressive given the stock's valuation, but management is signaling that they see the shares as undervalued relative to the AI-driven growth trajectory.
The 12-month subscription revenue backlog grew 14.2% year over year to $9.034B, providing visibility into the next four quarters. Total backlog of $27.4B grew 8.0%, a slower rate that reflects the mix shift toward shorter-term contracts. Free cash flow of $460M was down from $588M a year ago, driven by higher capital expenditures and working capital timing. That's a metric to watch in the back half.
What to watch next: whether the AI-driven ACV mix continues to accelerate or plateaus, and whether the 31% non-GAAP margin becomes a floor or a ceiling. The guidance raise suggests management sees room for both growth and margin expansion, but the GAAP-to-non-GAAP gap and the heavy buyback spending are risks that the headline beat doesn't capture.
