Taboola on September 18 announced an offer to acquire Dianomi, the UK-listed native ad network built for finance and business publishers, in a cash deal worth up to £27 million. Dianomi shares opened 74% higher in London on Friday, at 66.00p. Directors and other holders representing 75.3% of the register, of which 10.4% is the board itself, have already backed the bid.
The mechanics are straightforward and revealing. Taboola Europe Limited is paying 64 pence per share in cash, valuing Dianomi at roughly £19 million, with up to 24 pence per share of contingent consideration tied to Dianomi’s publishers adopting elements of Taboola’s standard commercial terms. MediaPost pegs the total between $34.3 million and $36.1 million depending on where sterling settles. Taboola expects to close before the end of 2026, subject to regulatory approval and a shareholder vote.
What Taboola is actually buying isn’t scale. Its Realize platform already claims more than 600 million daily active users across partners like NBC News and Yahoo, and it was upgraded in April with agentic capabilities that run campaigns autonomously against advertiser goals. What Dianomi brings is a curated network of more than 600 advertisers and publishers built around a single vertical: Reuters, The Wall Street Journal, CNN Business, and The Times on the supply side; Charles Schwab, Invesco, and Bank of America on the demand side. It’s one of the last remaining places on the open web where finance inventory is priced and packaged as its own thing.
The timing matters. Taboola posted Q2 2026 revenue of $476.8 million against analyst expectations of $499.4 million, cut its full-year guide from $2.03 billion to a $1.93–$1.96 billion range, and watched the stock drop 26% on the print. A £27 million tuck-in that plugs a premium vertical into an agentic performance platform is precisely the kind of move a company reaches for when the top of the funnel needs a story.
There’s a second-order consequence worth flagging. Dianomi’s finance placements have historically been agency-mediated and priced for the Schwabs of the world. Realize is self-serve and already runs at SMB spend levels. If the combined entity keeps Dianomi’s inventory inside a self-serve buying surface after close, the finance-context native lane, long walled off, becomes reachable for small B2B advertisers selling into fintech, insurance, and wealth management. For context on how sharply performance budgets are already rotating toward customer acquisition this year, see the IAB’s revised 2026 U.S. ad forecast and the parallel story of ChatGPT Ads opening self-serve globally.
The earnout clause tells you where the friction will land. Taboola isn’t paying full price until Dianomi’s publishers accept its commercial terms, which is another way of saying the Reuters and WSJ relationships are the actual asset, and they know it.
