("Rosslyn" or the "Company")

Grant and Cancellation of Options

Rosslyn (AIM: RDT), the provider of a leading cloud-based spend intelligence platform, announces the grant of options over ordinary shares of 0.1p each in the Company ("Ordinary Shares") and the concurrent cancellation of options over Ordinary Shares. This includes the grant of options to, and cancellation of options held by, a Director and a PDMR of the Company.

Following a review of employee incentives, the Remuneration Committee of the Board recommended that, given the prevailing share price of the Company and the increase in the issued share capital following the recent fundraise, the existing awards of share options were no longer a reasonable incentive and should be replaced to re-align the option scheme with the current share price and share capital.

Accordingly, on 22 July 2026, the Company cancelled, in aggregate, 8,230,942 options over Ordinary Shares ("Historical Options"), including those held by a Director and a PDMR of the Company as detailed below. The holders of the Historical Options have agreed to their cancellation with immediate effect.

On the same date, the Company granted, in aggregate, 13,026,380 options over Ordinary Shares (the "New Options"), a portion of which are to replace the Historical Options. This includes the grant of options to a Director and PDMR of the Company as detailed below.

Director/PDMR	Number of New Options granted	Exercise price of New Options granted	Number of Historic Options cancelled	Total number of options held following the grant and cancellation of options
Paul Watts, CEO	6,475,119	1.85p	4,899,371	6,475,119
Ed Riddell, CFO	3,631,497	1.85p	2,449,686	3,631,497

The New Options vest on the third anniversary of the grant date, expire on the tenth anniversary of the grant date, and are exercisable subject to the individual remaining an employee of the Company.

Following the cancellation of the Historical Options and grant of the New Options, the Company now has options outstanding over a total of 13,026,380 Ordinary Shares, representing 11.0% of the current issued share capital of the Company.
