Trading and Publisher Expansion Update

Revenues In-Line and Improved Gross Margin Performance

Return to growth and profitability in H2 25

Dianomi, a leading provider of digital advertising services to premium clients in the Business, Finance and Lifestyle sectors, is pleased to provide an update on trading for the 12 months to 31 December 2025 ("FY25").

The Group expects to deliver revenues of £27.4 million (FY24: £28.0 million), in line with market expectations*. Strongly improved gross margin performance led to a year on year increase in gross profit to £7.5 million (FY24: £7.3 million), and an improved EBITDA loss of approximately £0.3 million (FY24: £0.3 million), substantially ahead of market forecasts*. Cash at year end was £5.8 million (FY24: £8.8 million) reflecting a return to profitability in the second half of the year. All FY25 figures are subject to audit.

While trading was held back by a subdued market reflecting broader macroeconomic conditions, Dianomi improved its margin performance through ongoing operational optimisations. The Group also expanded its product offering and continues to offer a very compelling proposition, underpinned by excellent distribution capability, reaching 500 million digital devices each month across a network of more than 250 premium publishers.

Looking forward, following successful trials and subsequent onboarding in FY24, post year end Dianomi has expanded its partnerships with both CNN News and Associated Press, adding additional units on new pages to its existing footprint across both publishers' wider sites, highlighting the attractiveness of Dianomi's solution to its publishing partners. The benefits from the expansion with both CNN News and Associated Press are expected to flow from Q2 FY26 onwards.

Furthermore, reflecting the focus on new product development and AI, a new partnership with AI media infrastructure company Dappier, was announced earlier this week, to launch an advertising monetised AI-powered financial answers engine designed for premium publisher websites. By combining Dappier's conversational AI and monetization technology with Dianomi's scaled distribution across premium finance publishers and its financial advertising marketplace, the aim is to build a distributed AI answers network across the sector.

The Company looks forward to announcing its FY25 results in May 2026.

\* The Company believes market expectations for FY 2025 to be for revenues of £27.5 million, gross profit of £7.0 million and EBITDA loss of £1.1 million

Rupert Hodson, CEO of Dianomi, said:

"2025 saw a subdued market in which we traded well in the second half of the year following a challenging first half, returning to both growth and profitability. During the year we focused on investing in and developing our capabilities and our products. I believe the growth in our partnerships with CNN and Associated Press clearly demonstrate the value of the Dianomi proposition at the premium end of the market and the trust our partners place in our platform. Our focus is to fully leverage this opportunity. 2026 has seen some positive developments and we look forward to building on this momentum as the year progresses."
