The 2025 stall reached three independent lines, not just the federal book

• Key finding: Gartner's U.S. federal Insights contract value fell from about $225 million in March 2025 to $114 million in March 2026 (roughly halved, ~250bps of the CV-growth drag), but the weakness did not stay federal: GBS wallet retention — a channel with almost no federal exposure — rolled to 98.6% in the fourth quarter of 2025, ex-federal CV growth still decelerated to 3.5% by the first quarter of 2026, and Consulting's labor-based revenue fell 5% in 2025 before total Consulting revenue dropped 15% to $119 million in the first quarter of 2026, a second non-federal, non-Insights line showing the same client decision-hesitation.
• What it costs the cyclical read: the ~6.5-point swing in GTS currency-neutral CV growth on a ~$3.9B book is about $250M of annualized growth foregone, yet federal is only ~4% of contract value and ~250bps of the Q1 2026 drag — a self-lapping-federal story cannot by itself explain GBS wallet at 98.6% or Consulting down 15%.
• The counter, in the same breath: GTS wallet retention ticked from 96.0% to 96.5%, its first sequential improvement; management calls the federal book "rebaselined" and the Consulting softness "more timing-related than structural." One quarter is not a trend.

Generative AI is Gartner's highest-demand client topic and its top disclosed risk

• The demand side: management frames AI as the subject clients most want help with; AI content and its AskGartner tool are cited as drivers of engagement and renewal uplift, not yet of churn.
• The substitution side: the annual report escalated its risk language from FY2022 to FY2025 to name large-language-model substitution of syndicated advice directly — the structural reading the demand figures cannot rule out.
• Where it would show: pricing and wallet retention. Loss-reason tracking does not yet attribute lost renewals to AI, so the erosion is disclosed but not visible in the numbers — the bear case needs only buyer hesitation while AI is tested, not replacement today.

The only pure-play peer is shrinking on the very same model

• Scale and trajectory: Gartner is roughly 16x the revenue of Forrester, its only same-model peer, built on a 2,400-analyst research flywheel and a 40-year brand; since 2021 Gartner grew revenue about 37% while Forrester fell about 20%.
• Margins diverged: Gartner's operating margin moved 20.1% to 15.8%; Forrester's went 6.1% to negative 28.5% after a $110.7M impairment, with contract value down 6% to $292M and wallet retention at 87%.
• The two-edged read: the scale gap is real evidence of the moat, but the same wallet-retention weakness that surfaced at Gartner has run through Forrester for four years, and both firms attribute it to cyclical causes while neither names AI.

The business converts more than all its earnings into cash

Clients prepay 80-85% of Insights subscriptions up front, so Gartner runs on customer float rather than its own capital, and free-cash conversion has topped 100% of earnings every year since 2021. Two caveats temper the picture: 2024's headline cash flow was flattered by a $300M event-cancellation insurance gain, and the float's cash contribution turned negative — about $42M — in 2025 as contract value went flat. The engine is genuine and unusually clean, but no longer a growing tailwind.

A record buyback, funded partly with debt, at prices now underwater

• The policy: essentially all free cash flow goes to repurchases and none to a dividend; share count is down about 17% cumulatively, from roughly 92 million in 2018 to 75.6 million.
• The 2025 stretch: $2.0B bought back — about 1.5x operating cash flow — funded in part by $800M of new senior notes; book equity fell from $1.36B to $0.32B, with net leverage near 1.05x EBITDA.
• Mixed record: repurchases were accretive in 2019-2021, but the 2024-2025 peak buys sit roughly 50-70% underwater, and management calls buybacks "one of the bigger drivers" of its double-digit EPS-growth ambition — compounding to a bull, engineering to a bear.
