The Trade Desk, Inc. TTD

Key data

The business

The Trade Desk sells software that ad buyers, mostly agencies and large brands, use to place digital ads across streaming TV, websites, mobile apps, and podcasts. It is a demand-side platform: the buyer sets a budget and rules, and the system bids on individual ad slots in milliseconds. TTD keeps a fee, roughly a fifth of what flows through, and owns none of the media itself. That independence is the whole pitch. Google and Amazon run the same kind of auction but also sell their own inventory and audience data, so a buyer worried about the fox guarding the henhouse has historically chosen the neutral party. UID2, its identity system, and Kokai, its buying interface, are the tools meant to keep that buyer inside. The moat is the network of ad buyers and the identity graph beneath them: more spend routed through means better targeting and higher switching cost. The crack is that Amazon now offers a rival platform tied to the purchase history of hundreds of millions of shoppers, and it is taking share in exactly the streaming-TV budgets TTD leans on.

The numbers

Growth was the entire story here, and it broke this year.

The inflection is Q1 2026. After years above 20%, revenue rose only 3.0% in Q2 2026 against a year earlier while net income fell 29%, from $90M to $64M, and operating income slipped to $101.6M from $116.8M. The company came in under analyst estimates in both 2026 quarters, its first misses in years. Q4 2025, the seasonally biggest quarter, saw revenue jump to $846.8M and net income to $187.0M, making the first-half 2026 drop sharper still.

Revenue compounded about 25% a year from 2021 to 2025 and more than doubled; net income grew more than eightfold off the 2022 low. Then the engine downshifted hard. First-half 2026 revenue grew 7.2% while net income fell 25.9%, so the company is spending more to grow less: sales and marketing rose $33M, or 10%, faster than sales. At $14.43 the stock is priced at about 17 times trailing earnings and 8 times free cash flow, having thrown off $796M of free cash in 2025 on $2.90B of revenue. Cheap on the past, dear on the future the Street now models: consensus 2028 revenue is $2.88B, barely above 2025. The variant here: if streaming-TV budgets keep shifting to programmatic and TTD holds even a slipping share of a growing pool, $2.88B in three years is too low, and four quarters of double-digit growth would settle it.

Management

Founder-CEO Jeff Green bought $148M of his own stock over the trailing 12 months, including $136M across three consecutive days in early March 2026, into the collapse, against $5.8M of insider sales in the prior year. Those are discretionary purchases, not a pre-set plan, and they are the loudest signal in this file. Set against it is a buyback record that looks worse by the day: the company repurchased $1.38B of stock in 2025, more than its entire free cash flow, at prices that now read as the peak, plus $647M back in 2023. Capital returned above $50 that could have been deployed at $14. The balance sheet leaves room to keep going: $1.12B cash, net cash after debt, interest cover near 48 times. Pay leans on incentive targets reset this year, which the filing says drove the jump in personnel cost.

How it fails or surprises you

Amazon takes the streaming budgets. Amazon DSP bundles the same programmatic buying with first-party shopping data and undercuts on price. If TTD's share of connected-TV spend keeps slipping, 3% growth is the new floor, not the trough. The tell: another quarter under 10% revenue growth in Q3 2026, reported early November, with S&M still climbing faster than sales.

The margin the numbers explain least. Net income fell 26% in the first half while revenue grew 7% and S&M rose 10%. If that compression is structural, competition forcing both price and spend, then 17x earnings is a trap because the E is heading down. The bear is proven by operating margin back below the ≈14% of 1H 2026 in Q3.

CTV reaccelerates and the multiple re-rates (right tail). The company still will not disclose gross spend, CTV share, or retention, and that opacity held straight through the latest filings, so the market is blind on the one number that matters. If streaming budgets keep moving to programmatic and Kokai holds the big agencies, revenue can snap back to the mid-teens. At net cash with $796M of free cash flow, almost nothing is priced for that. The tell: one quarter back above 12% growth with steady margins, off a base where the founder just bought $148M.

Closing thoughts

The next two quarters will show whether this is Amazon winning or just a rough patch. The business still makes cash, sits on net cash, and is run by a founder who just staked $148M of his own money on the bounce. What the market cannot see, because the company will not show it, is whether TTD is losing the streaming-TV war to Amazon or merely digesting a platform transition and a hard comparison. The next two quarters of revenue growth answer it. If Q3 and Q4 2026 stay under 10%, the near-flat 2028 consensus is right and 17x is a mirage over falling earnings. If either prints double digits with stable margins, the stock is priced for a decline that is not happening. The left tail is real but not fatal: no debt and deep cash make the downside dead money and a value trap, not a wipeout. The right tail is a re-rate off a nine-year-low multiple.

The bet is still that agencies and brands keep routing their ad money through The Trade Desk instead of Amazon or Google, and keep paying it a cut. What breaks it is Amazon taking the streaming-TV budgets, and the pair to watch is quarterly revenue growth against the sales-and-marketing line: if spend keeps rising faster than sales while growth sits near 3%, the neutral-platform pitch is losing, whatever the founder paid.
