New Admission Date

Windar Photonics plc (AIM: WPHO), a wind energy technology company specialising in LiDAR‑based wind measurement and turbine performance optimisation, is pleased to announce that, further to the announcement made at 3:21pm on 24 August 2026 and following the publication of its FY25 Accounts, the Company has raised gross proceeds of approximately £0.76 million pursuant to the Directors' Intended Participation through the issue of 15,284,334 new Ordinary Shares (the "Directors' Shares") at the Issue Price of 5 pence per Ordinary Share.

As a result of settlement mechanics, David Lis is unable settle his full proposed investment of £250k through the Directors' Intended Subscription. To accommodate David's full proposed investment amount, David has subscribed for 4,100,000 new Ordinary Shares through the Directors' Intended Subscription and 900,000 new Ordinary Shares through the Retail Offer. As a result, the Retail Offer is being upsized by £45k to accommodate this. Further details will be included in the closing of Retail Offer announcement expected at 7.00 a.m. tomorrow.

In order to accommodate further participation from interested investors in the Fundraise, Paul Hodges has reduced his proposed investment by approximately £56k. Accordingly, the Placing and Direct Subscription, as announced at 6:24pm on 24 August 2026, has increased to a total of £4.11 million through the issue of 82,215,666 New Ordinary Shares at the Issue Price.

Each Director Share will have one warrant attached, exercisable at 10 pence for a period of 3 years (the "Fundraising Warrants"). The Fundraising Warrants will not be admitted to trading on AIM.

David Lis (Non-Executive Chairman), Paul Hodges (Non-Executive Director), Gavin Manson (Non-Executive Director) and Andreas Berg Nielsen (Chief Executive Officer) have participated in the Fundraise by subscribing for, in aggregate, 15,284,334 New Ordinary Shares at the Issue Price.

It is important to note that the aggregate amount to be raised under the Fundraise is unchanged.

The table below summarises the participation of each of the above-mentioned Directors in the Fundraising and further details are set out at the end of this announcement.

¹This figure does not include the 900,000 Ordinary Shares that David Lis will subscribe for pursuant to the Retail Offer.

² For the avoidance of doubt, this does not include any Ordinary Shares to be issued pursuant to the Retail Offer as announced at 7:00am on 25 August 2026

In addition, Tove Feld, whose appointment as a Non-Executive Director of the Company will become effective from Admission, has participated in the Fundraise by subscribing for 400,000 New Ordinary Shares at the Issue Price.

The table below summarises the participation of Tove Feld in the Fundraising and her resulting shareholding.
