FCF margin guided from 28.8% to high-teens — investment lag, or the new run-rate?

• The machine that was. FY2025 free cash flow $574M on $1.99B revenue — a 28.8% margin, the highest in company history and among the best in its public SaaS peer set (GoDaddy ran 31.8%). Every bull comp anchors on that number.
• The reset that came. Q1 2026 FCF margin fell to 21% from 30% the year before; GAAP operating margin swung from +9.0% in Q2-25 to -12.9% in Q1-26. Management then guided FY26 to high-teens FCF margin post-tender — an 800-1,000 bp compression by their own number.
• The date that decides it. Q2 2026 prints around August 5. TTM FCF margin above 22% on a stable opex ratio would be consistent with investment lag; at or below 15% would be consistent with a structural reset. Both sides have named this print as their resolution trigger.

Management retired 30% of shares at $92 — six weeks before the stock printed $53.

Funded with a $500M revolver, $1.15B of 2030 convertibles, and an externally-confirmed ~$250M PIPE from Durable Capital at a 5% discount (warrant strike of $104.73 referenced by Sherlock/specialist work but not externally confirmed) — equity sold at a discount in the same window the company bought stock back at a ~71% premium to today's $53.70. Three plaintiff firms opened pre-litigation investigations the week after the May 13 print. The action ages well if FY2026 FCF clears roughly $400M; below $350M, the capital structure is the constraint that matters.

Wix's own 20-F now names seven AI-native rivals — and Base44 proved the editor barrier collapses in twelve months.

• The first frontier shoe dropped. A major frontier-model vendor shipped a free AI-native website builder in mid-April 2026; the stock fell 31% the launch week. The 2025 20-F lists seven AI-native builders as Base44 competitors — the threat is now named in the filings, not just the bear deck.
• The Base44 paradox. Wix's own acquired AI app builder went from zero to $150M ARR in twelve months, off a six-month-old single-founder startup bought for $80M cash + $115M earn-out. Bulls call that owning the AI-native winner; the variant read is that it is empirical proof a 19-year editor moat now takes a year to replicate by anyone with subsidized compute.
• Operating data still works — for now. CMS share +33% YoY per W3Techs (March 2026), net revenue retention 105%, payments take-rate climbing from 1.5% to 1.7% over two years. The freemium funnel holds until a frontier-model owner pairs free generation with integrated payments.

Cheapest in the public peer set on every cash multiple, despite the highest FCF margin.

GoDaddy is the cleanest comp — same SMB website-builder model, comparable low-teens growth, near-identical FCF margin (31.8%). It trades at 2.4× Wix's EV/Revenue and 2.3× Wix's P/E. Either GoDaddy is wrong, or Wix is being priced for AI commoditization that has not yet shown up in the operating data. The balance-sheet cushion the tender consumed was what would have absorbed a wrong answer.

The bull's '5.6× forward FCF/share' and the bear's 'high-teens FCF' reference the same flattered cash number.

• Strip the stock-based comp. SBC ran $237M in FY25 — 11.9% of revenue and 4.4× GAAP net income. SBC-adjusted FCF is $337M, a 16.9% margin, not 28.8%. Treasury-stock recycling absorbs the dilution at variable cost, but the gap to peer non-GAAP definitions is real.
• Strip the earn-out lift. FY25 operating cash flow was lifted by a $156M increase in accrued/prepaid/other current liabilities (vs +$12M in FY24) — largely Base44 contingent-consideration cycled from R&D back into CFO ($114M of acquisition-related expense flowed through R&D). The $583M operating cash flow understates how much of FY25's headline conversion was acquisition-accrual mechanics rather than recurring engine power.
• What the GAAP line really says. FY25 GAAP net income of $51M was almost entirely a one-time $51M deferred-tax-asset release; pre-tax GAAP income was $1.1M. The 'earned the cost of capital' milestone is more a tax-timing event than an operating one.
