Contract Extension with Cadent

Crimson Tide plc (AIM: TIDE), the provider of the mpro5 operational compliance platform, is pleased to announce that it has agreed a 12-month uplifted extension to its contract with Cadent Gas Limited ("Cadent"), the UK's largest gas distribution network.

The extension takes the contract through to 30 September 2027 and represents annual recurring revenue ("ARR") of £486k, an increase of 4 % from the previous contract.

Cadent is a longstanding customer of Crimson Tide and has integrated mpro5 into its day to day operational and compliance workflows. The extension reflects the continued value that the platform delivers across Cadent's operations and the strength of the relationship between the two organisations.

The renewal is further evidence of the Company's customer retention strategy, which continues to secure and extend agreements with a number of the Group's largest customers.

Commenting on the contract extension, Jon Clarke, Chief Executive Officer of Crimson Tide plc, said:

"We are delighted to extend our relationship with Cadent, one of our most significant customers. This renewal demonstrates the mission-critical role that mpro5 plays in supporting the operations of large, complex enterprises, and reflects the tangible return on investment our platform delivers to customers every day. Securing extensions of this scale with our largest customers is central to our retention strategy and provides a strong, recurring foundation for future growth."
