Zoom Communications (NASDAQ: ZM) delivered a modest beat in Q2 FY2027. Revenue hit $1.277 billion, topping consensus by roughly $10 million. Non-GAAP EPS of $1.55 came in $0.07 above estimates. These headline numbers fit the gradual re-acceleration narrative Zoom has been selling for a year. The real story, however, is buried in the margin structure and the composition of that growth.
Enterprise revenue rose 7.8% year over year to $787.5 million. That is the strongest growth rate in three years, and for good reason. The enterprise segment now accounts for 61.7% of total revenue, up from 60.0% a year ago. The shift is real. Online revenue was essentially flat at $489.7 million, up just 0.6% YoY. The entire growth engine is coming from larger, stickier customers.
The trailing 12-month net dollar expansion rate for enterprise customers improved to 99% from 98% a year ago. Still below the 100% threshold that signals net retention, but the direction is encouraging. Zoom is not yet expanding spend within its existing enterprise base, but it is losing less ground. The number of customers contributing over $100,000 in trailing 12-month revenue grew 8.2% to 4,625. This suggests the company is adding higher-value accounts faster than it is losing wallet share in existing ones.
Non-GAAP operating margin contracted 130 basis points year over year to 40.0%. GAAP operating margin fell 180bps to 24.6%. The compression is not a surprise. Zoom has been investing aggressively in AI and product development, and the numbers confirm it. Research and development expense rose 17.5% YoY to $242.5 million, far outpacing revenue growth. As a percentage of revenue, R&D hit 19.0%, up from 17.0% a year ago. This is a deliberate trade-off. Management is betting that its AI-first customer experience portfolio—products like Zoom Virtual Agent (customer count up 256% YoY), ZoomMate, and the recently acquired Common Room and BrightHire—will drive the next leg of enterprise growth.
The bet is defensible, but the margin trajectory bears watching. Non-GAAP operating margin has now declined in three of the last four quarters. At 40.0%, it remains best-in-class among enterprise software companies, but the direction is down. The FY27 guidance implies non-GAAP operating margin of roughly 40.6% at the midpoint, essentially flat with the first half. This suggests management believes the R&D spend has peaked as a percentage of revenue, or at least that revenue growth will catch up.
GAAP net income of $1.54 billion was inflated by $1.6 billion in gains on strategic investments, mostly unrealized. Strip those out, and non-GAAP net income actually declined slightly year over year to $464.0 million from $471.3 million. The operating cash flow story is similar. Free cash flow fell to $472.4 million from $508.0 million a year ago, a 7.0% decline. The free cash flow margin contracted to 37.0% from 41.7%. This is partly a function of higher capex (purchases of property and equipment more than doubled to $22.4 million) and partly a working capital drag from higher accounts receivable and deferred contract acquisition costs.
Zoom repurchased 3.7 million shares for roughly $361 million in Q2, with $1.3 billion remaining under the current authorization. The buyback pace has moderated from the prior year, when the company spent $465 million in the same quarter. At the current run rate, the remaining authorization would cover roughly three more quarters. The buyback is a meaningful return of capital, but it is not accelerating despite the stock trading at roughly 22x forward non-GAAP earnings.
Guidance for Q3 and full-year FY27 was largely in line with expectations. Q3 revenue of $1.275 billion to $1.280 billion implies roughly 4.7% growth at the midpoint, a slight deceleration from Q2's 4.9%. Full-year revenue of $5.085 billion to $5.095 billion implies about 5% growth. Non-GAAP EPS guidance of $6.08 to $6.12 for the full year is roughly in line with consensus. The free cash flow guidance of $1.78 billion to $1.82 billion implies a margin of roughly 35.4%, down from 38.7% in the first half. That suggests management expects some working capital normalization in the back half.
The question for Zoom is whether the enterprise re-acceleration can sustain itself without further margin compression. The Q2 print shows the enterprise engine is working, but the cost of that growth is visible in the P&L. If the AI investments convert into higher net dollar expansion rates and faster enterprise revenue growth, the current trade-off will look prescient. If enterprise growth plateaus at 7-8% while R&D stays elevated, the margin story becomes a headwind. The next two quarters will tell which path Zoom is on.
