UK digital advertising group Dianomi plc reported a return to growth in the first half of 2026, with revenue up 2% year-on-year to £13.4 million and gross margin climbing to 28.9%. Expanded partnerships with CNN News and Associated Press, 67 new premium advertisers and positive post-period trading underpinned the improvement, while the company cut its EBITDA loss sharply and maintained a debt-free balance sheet with £6.0 million in cash.
Dianomi H1 Revenue Rises 2% to £13.4m as Margins Expand and Publisher Deals Drive Growth
Revenue for the six months to 30 June 2026 reached £13.4 million, compared with £13.2 million in H1 2025. On a constant-currency basis the increase was 4.5%. Gross profit rose to £3.9 million from £3.3 million as the gross margin expanded to 28.9% from 25.5%. The EBITDA loss narrowed to £0.1 million from £0.6 million a year earlier, and the loss per share improved to 1.64 pence from 2.63 pence.
Cash stood at £6.0 million at the period end (31 December 2025: £5.8 million; 30 June 2025: £5.7 million), with no borrowings. Impressions delivered across the platform increased 10% to 22.6 billion from 20.6 billion, driven largely by deeper placements with CNN News and Associated Press that began contributing from the second quarter.
Dianomi added 67 new premium advertisers, a 56% year-on-year rise, taking the total to 225 (H1 2025: 197). It onboarded eight new publishers (versus six a year earlier), bringing the publisher count to 294 from 285. Average advertising spend was £109,000 (H1 2025: £113,000). Programmatic supply revenue fell to £116,000 from £857,000, reflecting the non-repeat of a significant one-off campaign in the prior period.
The company launched Dianomi Interactive (new interactive ad formats), established a dedicated Investor Relations and Corporate Communications vertical with a new Head of Insights, and partnered with AI firm Dappier to develop a monetised AI-powered financial answers engine for publisher sites. Further strategic investment continued in people, AI tools and the core platform.
Post-period trading remained positive: revenue in July and August rose 14% year-on-year, and a further 15 advertisers joined the platform after 30 June.
Investors Likely to View Dianomi’s Return to Growth and Stronger Margins Positively
As a small AIM-listed company with a market capitalisation of approximately £7.8 million (share price recently around 26p), Dianomi’s results are closely watched for evidence of stabilisation after prior periods of soft demand and traffic pressure. The combination of a clear return to revenue growth, a substantial margin expansion, a sharply reduced loss and continued positive cash generation is likely to be viewed constructively by investors focused on operational recovery and balance-sheet strength. The 14% July–August revenue uplift and ongoing advertiser pipeline provide near-term momentum signals. No material negative surprises emerged on cash or debt, supporting confidence in the company’s ability to fund further product and partnership investment.
Dianomi: AIM-Listed Premium Ad Platform Serving 294 Publishers, FY25 Revenue £27.4m, US Delivers £10.6m in H1
Dianomi, founded in 2003 and listed on AIM, provides contextual and native digital advertising focused on premium business, finance and lifestyle audiences. It reaches audiences across more than 250–294 premium publishers (including Reuters, CNN Business, The Times and WSJ) and serves advertisers such as Charles Schwab, Invesco and Baillie Gifford. The group operates from London, New York and Sydney.
Full-year 2025 revenue was resilient at £27.4 million (2024: £28.0 million), with a return to growth and profitability in the second half of that year. The broader digital publishing sector has faced structural headwinds from AI-generated summaries and “zero-click” search, which reduced traffic and contributed to a 14% drop in impressions in 2025. Dianomi has responded by deepening relationships with major global publishers, expanding into multi-format and interactive ads, building proprietary audience and insights products, and investing in AI capabilities (including the Dappier partnership and internal AI bidding and categorisation tools).
Geographic revenue in H1 2026 showed the US remaining dominant at £10.641 million (H1 2025: £10.227 million), with EMEA at £2.378 million and APAC at £0.382 million.
Dianomi Eyes H2 Momentum with Debt-Free Balance Sheet, Expanding AI & Interactive Products Amid Cautious Market
Management expects the cautious advertiser environment and ongoing structural shifts in digital publishing to persist. However, the company believes its premium publisher network, expanding product suite (including interactive formats and the IR/corporate communications vertical) and AI initiatives position it to capture opportunities as the market evolves. Positive trading momentum into the second half, a building advertiser pipeline and a strong, debt-free balance sheet support continued investment. Full-year performance will depend on sustaining the recent growth trajectory and converting the expanded CNN/AP and new-product pipelines.
