Rupert Hodson, Chief Executive Officer of Dianomi, said:

"We are pleased with the progress made during the first half of 2026, with a return to revenue growth, a significant improvement in gross margin and a substantially reduced EBITDA loss. This performance was achieved despite an advertising market that remains cautious and the continuing structural changes affecting the publishing industry, including the growing adoption of AI and 'zero-click' search.

"During the period, we continued to strengthen the business, attracting 67 new premium advertisers, expanding our relationships with leading global publishers including CNN News and Associated Press, and broadening our proposition through the launch of Dianomi Interactive and our new Investor Relations and Corporate Communications vertical. Our partnership with Dappier also demonstrates how we are responding to changes in the way audiences discover and consume content and seeking to create new opportunities from the growing adoption of AI.

"We continue to invest in the business with confidence in the strength of the Dianomi platform and its differentiated position in the market. Over more than 20 years, we have built a network of premium publishers which enables leading brands to reach valuable and difficult-to-access audiences in trusted environments. Together with our strong, debt-free balance sheet, expanding product offering and continued investment in technology, this provides a strong foundation from which to develop the business.

"Trading since the period end has remained positive and we enter the second half with encouraging momentum. While we remain mindful of the wider market environment, we are focused on executing our strategy and capitalising on the opportunities available to Dianomi as the digital advertising market continues to evolve."

Chief Executive's Statement

Introduction

We have made encouraging progress through the first half of 2026. Our expanded partnerships with CNN News and Associated Press ("AP") began contributing to revenue from Q2 2026 onwards and, together with the continued development of our multi-format digital advertising platform, supported a return to revenue growth in the period.

The market backdrop remains both economically and structurally challenging, but we have continued to attract new premium advertisers and publishers to the Dianomi platform and to deepen a number of our existing relationships. This reflects the continued appeal of our premium, contextual and increasingly multi-format proposition. Combined with a strong, debt-free balance sheet, we believe the Group remains well positioned to continue investing in its platform, products and commercial capabilities and to pursue the opportunities available within a changing digital advertising market.

Operating Review

Readership levels declined materially across parts of the digital publishing market during 2025, which affected Dianomi and contributed to a 14% reduction in impressions during that year. This reflected, among other factors, changing patterns of content consumption, including the increasing use of AI-generated and so-called "zero-click" summaries which can reduce the need for users to visit publisher websites directly.

Against this backdrop, impressions delivered across the Dianomi platform increased by 10% in H1 2026 to 22.6 billion, compared with 20.6 billion in H1 2025, principally reflecting the expansion of our relationships with CNN News and AP. This demonstrates the ability of the Group to mitigate some of the wider pressure on publisher traffic by broadening and strengthening its supply relationships with high-quality global publishers.

Advertiser and publisher engagement across the Dianomi platform remained positive. Average advertising spend was £109k during the period (H1 2025: £113k). During the period, 67 new advertisers and eight new publishers joined the platform, compared with 43 and 6 respectively in H1 2025, reflecting continued new business activity even as decision-making among some advertisers remains cautious in the current market environment. The number of publishers and advertisers in the period stood at 294 and 225 respectively, compared to 285 and 197 in H1 2025.

During the period, we continued to strengthen our relationships with globally recognised publishing partners, expanding our partnerships with both CNN News and AP and adding Dianomi units to new pages across their wider sites. As indicated at the time of our FY25 results, the benefits of these expanded relationships began to flow through from Q2 2026 and both partnerships provide further opportunities for the Group as they continue to scale. They also demonstrate Dianomi's ability to establish and develop relationships with some of the world's leading media brands.

In April, we successfully launched Dianomi Interactive, new advertising formats which are designed to enable audiences to interact directly with an advertising unit, whether by exploring products further, participating in a poll or engaging with other interactive elements. By encouraging greater engagement with advertising content, Dianomi Interactive has the potential to increase dwell time and click-through rates while also generating additional engagement data. Initial feedback from premium advertisers and publishers has been encouraging, with a growing pipeline of campaigns currently in development.

We also launched a dedicated Investor Relations and Corporate Communications vertical, designed to help listed companies communicate more effectively with key investor audiences across institutional investors, financial advisers and the increasingly important retail investor community. This proposition has been further strengthened by the appointment of a new Head of Insights, who will lead the development of enhanced audience intelligence and data-driven insights to help clients better understand and engage their target investor base. Together, these developments broaden Dianomi's proposition within an adjacent specialist market that is closely aligned with the Group's longstanding expertise in financial services.

Our proprietary products also continued to gain traction. Dianomi Audiences, which provides buyable audiences built using curated publisher lists, contextual keyword targeting and Dianomi's first-party historical campaign data, experienced increased advertiser engagement during the period. Dianomi Insights, our analytics tool that helps brands understand how their media coverage compares with industry peers, published 7 industry reports during the period. We are also increasingly using AI to enhance the categorisation of publisher pages, providing advertisers with deeper insight into their brands, audiences and the sectors in which they operate.

Programmatic supply revenue reduced to £116k during the period from £857k in H1 2025. H1 2025 benefited from a significant one-off campaign delivered programmatically which did not repeat during H1 2026.

Market Commentary

Over recent years, we have sought to broaden and strengthen Dianomi's proposition in response to a rapidly evolving digital advertising landscape. This has included developing the Group from its historically native-led offering towards a broader multi-format platform, investing in programmatic capabilities and launching new products and services. We have also continued to deepen relationships with major publishing partners and to extend our advertiser proposition into adjacent verticals, including premium lifestyle and investor relations and corporate communications.

We believe these initiatives have strengthened the underlying business and broadened the opportunities available to the Group. However, the market in which we operate continues to undergo significant structural change.

The wider advertising market remains cautious against an uncertain macroeconomic backdrop, while the accelerating adoption of artificial intelligence and "zero-click" search functionality continue to influence how audiences discover and consume digital content and, in turn, traffic levels across parts of the publishing industry.

Dianomi is adapting its proposition in response to these changes. In March, we announced a partnership with AI media infrastructure company Dappier to develop a monetised, AI-powered financial answers engine designed to be embedded directly within publisher websites. As AI-generated news summaries and conversational interfaces reshape the way users consume financial information, publishers increasingly need to find new ways of retaining audience engagement within their own environments. The partnership is intended to enable publishers to use their journalism and archives to power conversational AI experiences hosted on their own sites, retaining audiences while creating a new advertising-led revenue opportunity for publishers and financial brands. There are ongoing conversations with publishers regarding units within their websites and advertisers are also showing strong interest in the brand agents ad units as a new, controlled conversational ad unit.

Internally, we are also investing selectively in AI to improve the effectiveness and efficiency of the Dianomi platform. These initiatives include a proprietary AI-driven bidder trained on Dianomi's historical campaign data to optimise bids while managing campaign budgets and pacing constraints, together with an AI-powered content categorisation tool designed to improve targeting and provide richer insights for advertisers.

We believe our established relationships with premium publishers and advertisers, specialist expertise in financial services, proprietary data and contextual technology leave Dianomi well placed to respond to the changes taking place across the digital advertising industry.

Financial Review

Group revenue increased by 2% to £13.4 million (H1 2025: £13.2 million), and by 4.5% on a constant currency basis. This follows FY25 revenue of £27.4 million (FY24: £28.0 million) and represents a return to revenue growth, reflecting continued new business activity together with the CNN News and AP relationships beginning to contribute from Q2 2026, as anticipated at the time of our FY25 results.

Gross margin increased to 28.9% (H1 2025: 25.3%), continuing the improvement seen during the second half of FY25. Gross profit consequently increased by 18% to £3.9 million (H1 2025: £3.3 million), compared with £7.5 million generated in FY25 as a whole. The improvement reflects both the changing revenue mix and the Group's continued focus on disciplined publisher economics.

The improved gross profit performance resulted in a significantly reduced EBITDA* loss of £0.1 million (H1 2025: loss of £0.6 million), building on the improvement seen during the second half of FY25. FY25 EBITDA was a loss of £0.3 million, in line with FY24 despite the reduction in revenue.

Loss before tax reduced to £0.3 million (H1 2025: loss of £0.7 million). The tax charge for the period was £0.06 million (H1 2025: £0.07 million), principally relating to the Group's US subsidiary, resulting in a loss after tax of £0.35 million (H1 2025: loss of £0.8 million). Basic loss per share was 1.17 pence (H1 2025: loss of 2.63 pence).

Cash generated from operations was £0.05 million during the period, compared with cash used in operations of £2.6 million in H1 2025. As at 30 June 2026, the Group had no borrowings and cash of £6.0 million (H1 2025: £5.7 million; 31 December 2025: £5.8 million), maintaining a strong, debt-free balance sheet which provides the Group with the financial flexibility to continue investing selectively in its platform and growth initiatives.

Net assets at 30 June 2026 were £6.7 million (31 December 2025: £6.8 million; 30 June 2025: £7.3 million).

Outlook

The digital advertising ecosystem continues to evolve rapidly, bringing both challenges and opportunities. Against this backdrop, our strategy remains focused on the areas in which Dianomi has established differentiated strengths: connecting premium brands with valuable audiences in trusted publisher environments, while continuing to broaden our formats, products and addressable markets.

The progress made during the first half demonstrates the benefits beginning to emerge from the investments and commercial initiatives undertaken over recent periods. In particular, the expansion of our relationships with CNN News and AP, the development of our multi-format proposition, increasing adoption of our proprietary products and our investment in new opportunities including AI, Investor Relations and Corporate Communications provide a broader base from which to develop the business.

Trading since the half year has remained positive and has continued the progress seen during the first half. Although advertiser decision-making remains cautious and we expect the wider market environment and structural changes affecting publisher traffic to continue to present challenges, demand for Dianomi's premium, contextual proposition remains resilient.

With an expanded publisher footprint, a broader product offering and a strong, debt-free balance sheet, we believe Dianomi is well positioned to continue executing its strategy and pursuing the opportunities available to the Group.
