New York, Belfast and London, 29 July 2026 - Diaceutics PLC (AIM: DXRX), a leading technology and solutions provider to the pharma and biotech industry, today provides a trading update for the half year to 30 June 2026 ('H1 2026'), highlighting strong revenue growth, continued addressable market capture and record forward revenue visibility.

Ryan Keeling, Diaceutics' Chief Executive Officer, commented: "I am more confident than ever in Diaceutics and the long-term value we can create for shareholders. H1 revenue grew 22% at constant currency to £17.5 million, alongside a material improvement in the quality and visibility of that growth.

ARR reached £28.8 million, increasing 75% period-on-period and 45% since December 2025. NRR increased to 146%, while gross churn fell from 19% to just 9%. Customers are staying longer, expanding their relationships and committing through recurring, multi-year contracts, creating a more predictable and durable business with high revenue visibility.

We are demonstrating good operating leverage. Revenue is growing faster than the underlying cost base, gross margin increased to 87%, and we expect to report H1 Adjusted EBITDA of £1.1 million.

Precision for All is expanding our addressable market, while PMx is creating deeper enterprise relationships and longer-duration recurring revenue. Our proprietary diagnostic data, technology and application of AI provide a differentiated platform from which to capture this opportunity.

We enter H2 with record forward visibility. Our £43.7 million order book includes £15.7 million of revenue contracted for H2, which including weighted pipeline, gives 91% visibility on achieving FY 2026 median analyst consensus revenue estimates.

We are growing revenues, increasing recurring revenue, retaining and expanding customers, and building our order book to record levels. That combination gives me strong confidence in delivery for FY 2026 and in our continued ability to create significant long-term shareholder value."

Underpinning this ARR growth was Net Revenue Retention ('NRR') of 146%, and gross ARR churn of 9% (30 June 2025: NRR of 118% and gross churn of 19%). Recurring revenue represented 61% of total revenues over a Trailing Twelve Month ('TTM') period (58% for TTM ended 30 June 2025).

Delivering on median consensus revenue estimates would see a 38:62 H1:H2 split of 2026 revenue, similar to and supportive of prior year seasonality (FY 2025: 38:62).

Adjusted EBITDA* is expected to be £1.1 million, compared with £0.1 million in H1 2025, while gross margin increased and is expected to be 87% (H1 2025: 83%).
