The Derating

The Derating

Gartner is a subscription research and advisory business that grew revenue from $4.1 billion in 2020 to $6.5 billion in 2025, and the stock still lost roughly three-quarters of its value — from an intraday peak of $551.80 in November 2024 to $140.19 in July 2026 [1]. This chapter establishes what the company is, how it earns, why the market repriced it, and the question the rest of this report exists to answer.

What Gartner is

Gartner sells research and advice by subscription. It serves more than 13,000 enterprises across roughly 90 countries, and reports in three segments: Business and Technology Insights (renamed from "Research" in 2025), Conferences, and Consulting [2]. The core is Insights: recurring subscriptions that give executives access to Gartner's analysts, proprietary research, and decision tools. That segment produced $5.07 billion of 2025 revenue at a 77% gross contribution margin — the economic engine of the company [3]. Conferences ($645 million) and Consulting ($552 million) round out the model but are secondary [4].

The model has genuinely attractive properties. Subscriptions are prepaid and renew on a rolling basis; the marginal cost of serving one more seat with existing research is low, which is why Insights carries a mid-70s gross contribution margin. For most of the last decade this compounded: revenue rose every year from 2016 to 2025, and the share count fell as the company returned cash. That is the picture — a wide-margin, cash-generative franchise — against which the market repriced the stock.

What the market did

The share price rose roughly seven-fold from its 2018 year-end ($128) to its 2024 peak, then gave nearly all of the late-cycle gain back. From the November 2024 high of $551.80, the stock fell to $140 by mid-2026 — a decline of about 75% — with the sharpest legs down after the mid-2025 and early-2026 results [8].

At $140, the market values Gartner's equity at about $10.6 billion — roughly 15 times the $9.65 of GAAP earnings the company reported for 2025 [9]. A business that grew revenue every year now trades at a multiple that prices in little further earnings growth. The reason the market gives is visible in the operating data.

The crack in the franchise

Contract value — the annualized run-rate of subscriptions in force — is the leading indicator for a business that recognizes revenue over the life of a subscription. It stalled in 2025. Global Technology Sales (GTS) contract value, the larger of the two sales engines, was flat at $3.91 billion, and total Insights contract value grew just 1% [10]. More telling, wallet retention — how much existing clients spend on renewal versus a year earlier — fell below 100% for the first time in years: GTS dropped to 96% from 102%, and Global Business Sales (GBS) to 99% from 106% [11]. A figure below 100% means the installed base is contracting in dollars, not expanding.

Management attributes the slippage to two forces it names directly. The first is the US public sector, especially the federal government, where contract value fell by double digits and dragged on the whole book [13]. The second is broader: "decreased spending from existing clients" — enterprises trimming discretionary research budgets [14]. Layered on top is an investor debate the filings do not settle: whether large-language-model tools erode the value of paying for human research and advice. Public-sector cyclicality and a structural question about the product are difficult to separate in a single year of data — and the market, so far, has priced them together.

The earnings line looks worse than the operating reality, which is worth separating out. GAAP net income fell from $1.25 billion to $0.73 billion and diluted EPS from $16.00 to $9.65, but two items distort the comparison: a $150 million goodwill impairment on the Digital Markets unit in 2025 (sold in February 2026 for about $110 million), and a large event-cancellation insurance gain that had lifted 2024 [15]. Operating income fell 11% to $1.03 billion, and roughly $150 million of that decline was the non-cash impairment [16]. The real deterioration is not yet in reported profit; it is in the run-rate.

What is still intact

Whatever the market fears, it is not solvency. Gartner generated $1.29 billion of operating cash flow in 2025, held $1.7 billion of cash, and had about $1.0 billion of undrawn revolver capacity [18]. Against roughly $2.98 billion of long-term debt, that leaves net debt near $1.26 billion — under one year of operating cash flow [19]. The subscription model collects cash in advance, so working capital funds itself. Bankruptcy risk, for this business at this leverage, is remote.

The company has also spent heavily on its own stock. In 2025 it repurchased 7.0 million shares for about $2.0 billion — reducing the diluted share count that has fallen from about 92 million in 2018 toward 76 million today [20]. That buyback was executed at an average price near $286 — well above where the shares now trade, a fact the capital-allocation chapter will need to weigh. The machine that shrinks the share count is intact; whether it was pointed at the right price is a separate question.

The question this report answers

Gartner arrives as a fallen star: a high-margin, cash-generative franchise that the market once priced for durable double-digit growth and now prices for stagnation, after contract value flatlined and wallet retention slipped below 100% for the first time in years. The central question this report exists to answer is whether that roughly 75% derating correctly prices a permanent, AI- and budget-driven impairment of the research-subscription franchise, or overshoots a still-cash-generative, lightly levered business suffering a mostly cyclical stall in its growth engine.

Everything that follows tests one side of that question or the other: how the subscription economics actually behave, how much of the slowdown is the US public sector versus the whole book, whether the AI threat shows up in the numbers, what management has done with capital, who owns the stock and how they are paid, and what price today implies. The evidence is genuinely two-sided, and the chapters ahead are built to weigh it rather than to settle it by assertion.
