Toll on Ad Spend

Toll on Ad Spend

The Trade Desk sells no advertising inventory. It rents advertisers a buying platform and keeps a fee on whatever they spend through it — $2.90 billion of revenue in FY2025 on $13.39 billion of client spend, a 21.6% cut [1]. The business is profitable, debt-free and generates cash. The stock is down 87.6% from its December 2024 peak. The gap between those two sentences is what this report is about.

What the company does

Digital advertising is bought in two broadly different ways. Inside the "walled gardens" — Google, Meta, Amazon's own retail properties — an advertiser buys inventory the platform itself owns and sells. Everywhere else, on what the industry calls the open internet, inventory is auctioned. The Trade Desk is a demand-side platform, or DSP [2]: the software an ad buyer uses to bid in those auctions across connected TV, video, mobile, display and audio [3].

Its clients are advertising agencies and brands, contracted under master services agreements, and the revenue mechanic is simple: "a platform fee generally based on a percentage of our clients' total platform spend," plus fees for data and value-added services layered on top [4]. The company owns no inventory, which is the whole pitch — it argues it can pick the best impression for a buyer because it has no impressions of its own to favour [5].

The addressable pool is large and growing. Digital advertising is reported at over $700 billion of annual spend and more than 70% of the total advertising market; global advertising TAM passed $1 trillion for the first time in 2024; and viewing continues to migrate from linear television to connected TV [6]. That is the tailwind the equity story has always leaned on.

Source: Q1 2026 prepared remarks, CFO commentary — video "a low-50s percent," mobile "a high-28s percent," display "a low double-digit share," audio "around 6%"; midpoints plotted [7].

Two concentrations matter. Video, which includes CTV, is roughly half the business and still rising as a share of mix; and the United States was about 82% of Q1 FY2026 revenue, leaving international at 18% despite a decade of investment [8]. The company ended FY2025 with 3,843 full-time employees in 21 countries, and its own competition disclosure names Google and Amazon as the large, well-established rivals [9].

Client stickiness has historically been the franchise's best evidence. The FY2024 10-K reports a client retention rate above 95% in each of the last eleven years — though the same paragraph notes those master agreements typically run one year and are terminable on 60 days' notice, so retention is a behavioural fact rather than a contractual one [10].

Volume and the cut

Because the fee is a percentage of spend, the business has two independent drivers: how much money flows across the platform, and what share of it the company keeps. Management discloses the first as gross spend and has disclosed the second, historically, as take rate.

Through FY2024 those two moved together. Gross spend compounded at 24–25% a year for three consecutive years and the take rate sat in a narrow band around 20.3% [11][12][13]. FY2025 broke the pattern. Gross spend grew 11%. Revenue grew 18% [14].

Sources: FY2025 10-K [15]; FY2024 10-K [16]; FY2023 10-K [17]; FY2022 10-K [18]; FY2021 10-K [19].

The seven-point wedge between those two bars is the take rate rising, and the company says as much. FY2025 revenue growth was driven by the 11% spend increase plus "a higher proportion of revenue earned from client spend due to increased utilization of our value-added services and data; and higher platform fees," with Kokai — the platform's major upgrade — and "increased pricing associated with value-added services and data" named explicitly [20]. The Q1 FY2026 10-Q repeats the construction for the March quarter's 12% revenue increase, again crediting "increased pricing associated with value-added services" [21].

Source: derived from reported revenue and gross spend, FY2021–FY2025 10-Ks [22][23][24].

My read is that gross spend, not revenue, is the cleaner measure of whether this franchise is winning, and on that measure FY2025 was a step down of a different order than the reported 18% suggests. Volume growth halved while price did the work.

Two things cut against reading that as structural decay. First, FY2022 saw a comparable take-rate step — from 19.4% to 20.4% — and gross spend growth then held at 24–25% for two more years, so a rising cut is not by itself a distress signal [25][26]. Second, the mix genuinely is shifting toward higher-priced data and measurement services, which is a real product story and not only a pricing lever. What would change my read in the other direction is a further year of single-digit gross spend growth: pricing can substitute for volume once, not repeatedly.

One disclosure detail is worth recording: the gross spend footnote's standing sentence telling readers to expect the take rate to fluctuate, carried from FY2021 through FY2024 [27][28][29][30], is gone from the FY2025 10-K, the year the take rate moved 130 basis points, replaced by a cross-reference [31], a retirement documented in full across three calls and the FY2025 10-K in Pricing and Take Rate; gross spend itself is still disclosed annually and still not quantified in the quarterlies [32].

The deceleration, quarter by quarter

Revenue growth has fallen in every quarter since the start of FY2025, and the guided June 2026 quarter continues the sequence.

Sources: quarterly revenue as reported in each quarter's Form 10-Q [33][34][35][36], with Q4 FY2025 derived as the full year less the first three quarters [37]; 2Q26 from the "at least $750 million" guide given on the Q1 2026 call [38].

Q1 FY2026 delivered $689 million of revenue at 12% growth and $206 million of adjusted EBITDA, a 30% margin; management guided the June quarter to "at least $750 million" of revenue [39] and roughly $260 million of adjusted EBITDA [40]. Against the $694 million booked a year earlier, that guide implies about 8% growth. Management's account of the slowdown is macro and vertical-specific: geopolitical uncertainty, CPG brands facing consumer softness and input-cost inflation, and tariffs restraining automotive [41]. Full-year 2026 adjusted EBITDA margin is still guided to at least 40%, roughly level with 2025 [42].

Asked directly whether competitive pressure had increased, the CEO's answer was no — "I think Google was a far better competitor than Amazon is today or, frankly, will likely ever be" — arguing that Amazon's economics tie it to selling its own inventory [43] and that the market has become more fragmented and noisier rather than more hostile [44]. The company's own risk factors are less sanguine, noting that walled-garden inventory providers "may exclusively sell their own inventory directly to advertisers, which prevents us from competing with them entirely for such inventory" [45]. Both statements can be true; they do not settle whether the 11% is macro or share.

What the accounts look like

Sources: FY2025 revenue and operating income, FY2025 10-K [46]; free cash flow derived as FY2025 operating cash flow of $993 million [47] less $197 million of purchases of property and equipment [48]; net cash is cash, equivalents and short-term investments at March 31, 2026 with no debt outstanding [49].

FY2025 turned $2.90 billion of revenue into $589 million of operating income — a 20% GAAP operating margin, up from 17% — and $443 million of net income [50], or $0.90 per diluted share [51]. Operating cash flow was $993 million, up 34% [52]. There is no debt: the credit facility was undrawn at year-end with $445 million available, so the company carries no near-term funding requirement [53].

Three features of the accounts shape how the numbers should be read.

The balance sheet is mostly other people's money in transit. At December 2025, receivables were $3.77 billion against payables of $3.01 billion [54] — both far larger than annual revenue, because the company invoices clients for the full cost of the media and remits it to suppliers. Total assets of $6.15 billion are dominated by that float, not by operating capital.

Adjusted EBITDA and GAAP earnings diverge by roughly the cost of the workforce's equity. FY2025 adjusted EBITDA of $1.20 billion reconciles to $443 million of net income mainly by adding back $491 million of stock-based compensation, plus $116 million of depreciation and $215 million of tax [55]. Stock compensation exceeded net income. The same wedge appears quarterly: Q1 FY2026 GAAP earnings were $0.08 per diluted share against $0.28 adjusted [56]. Any multiple quoted on this company needs its basis stated.

Buybacks have been large and, so far, badly timed. FY2025 saw 26.2 million Class A shares retired for $1.4 billion — an average of roughly $53 a share against a July 2026 price of $17.29, so that outlay would buy the same shares today for about $453 million [57]. Repurchases continued at $164 million in Q1 FY2026 [58]. The buying reduced the share count, and it was funded from cash flow rather than borrowing; it was also done at three times the current price.

Control sits with insiders. Class B shares carry ten votes each, and Class B holders — officers, employees, directors and affiliates — held approximately 49.9% of total voting power at December 2025, with automatic conversion to Class A not scheduled until December 2035 [59]. Co-founder Jeff Green remains CEO. What that concentration is worth to an outside holder depends on the record of the decisions it has produced, which this chapter does not settle.

The price and the arithmetic

The de-rating runs to 87.6% from the December 2024 peak, and it has been continuous rather than a single gap.

Source: daily closing prices as reported, month-end observations; all-time closing high of $139.51 on December 4, 2024.

The shares closed at $17.29 on July 24, 2026, against an all-time closing high of $139.51 on December 4, 2024 — a decline of 87.6%. FY2024 ended at $117.53 and FY2025 at $37.96, so the fall spans two calendar years of continuous compression rather than one event. Over the same period revenue rose from $2.44 billion to $2.90 billion and net income from $393 million to $443 million [60].

At $17.29 on 471.0 million shares outstanding at March 31, 2026, the equity is worth about $8.14 billion; net of $1.41 billion of cash and short-term investments and with no debt, enterprise value is roughly $6.74 billion [61].

Sources: derived from the July 24, 2026 close of $17.29 and 471.0 million shares outstanding [62]; FY2025 operating income and net income [63] and diluted earnings per share [64]; adjusted EBITDA and stock compensation [65]; operating cash flow [66] and capital expenditure [67]; FY2026 consensus per analyst estimates.

The spread down that column is where the disagreement sits. On adjusted EBITDA the business changes hands at 5.6 times enterprise value. On GAAP operating income, which charges the $491 million of equity compensation that keeps 3,843 employees in place, it is 11.4 times. Neither number describes a company priced for the 20%-plus growth of FY2024, and the second is not obviously cheap for a business guiding to 8% revenue growth in the current quarter. These three rows are orientation only; the full eight-row ladder, including the after-stock-compensation measures, sits in Cash and Share Count.

Consensus has moved with the price rather than ahead of it. Sell-side estimates put FY2026 revenue near $3.18 billion and FY2027 near $3.48 billion — growth of roughly 10% in each year, against 18% delivered in FY2025 — and FY2026 adjusted EPS around $1.85, with downward revisions outnumbering upward ones by roughly nineteen to two over the preceding month. The average published target is $24.32, and the analyst body covering the name is split, with more holds than buys and five outright sell ratings.

What this report tests

The facts above describe a business and a price that have moved in opposite directions. The Trade Desk is a debt-free, cash-generative, founder-controlled percentage-fee intermediary in programmatic advertising that has lost 87.6% of its market value while its revenue and profits rose, and in the year the shares fell hardest gross spend grew 11% rather than 25%, with pricing making up the difference.

This report tests: is the halving of gross-spend growth on The Trade Desk's platform — from 24–25% a year through FY2024 to 11% in FY2025 and single-digit guided revenue growth by mid-2026 — a repairable macro and execution stumble, or the onset of durable share loss to the walled gardens; and does the price at $17.29, roughly 11 times GAAP operating profit with $1.4 billion of net cash behind it, already pay for the pessimistic answer?

The evidence needed to settle it is specific and mostly knowable: whether gross spend reaccelerates or stays in single digits; whether take rate keeps rising and whether clients tolerate it; whether the CTV and retail-data mix shift is winning budget or merely repricing the budget already there; whether the leadership turnover of 2025–26 reflects an upgrade or instability; and what a business growing at 10% with a 40% adjusted-EBITDA margin and $491 million of annual equity compensation is actually worth. Those are the threads the chapters that follow pick up.
