Windar Photonics (LSE:WPHO) has opened a retail share offer through the BookBuild platform as part of a wider fundraising initiative ahead of the planned resumption of trading in its shares on AIM. The company is seeking to raise up to £200,000 by issuing as many as 4,000,000 new ordinary shares at 5 pence each.
The offer price represents a substantial discount to the company’s final closing share price before trading was suspended on AIM. Investors participating in the retail offer will also receive a three-year warrant for each new share subscribed, exercisable at 10 pence per share.
Participation is restricted to existing Windar Photonics shareholders in the UK and is being made available through eligible intermediaries participating in the BookBuild platform. The structure is intended to give retail shareholders an opportunity to participate alongside investors involved in the company’s separate placing and direct subscription.
Completion of the retail offer is dependent on several conditions. These include successful completion of the placing, publication of Windar Photonics’ audited accounts for 2025, the lifting of the current AIM trading suspension and admission of the newly issued shares to trading. Admission is currently targeted for 28 August 2026.
By including a dedicated retail component in the broader capital raise, Windar Photonics is seeking to provide existing individual shareholders with access to the fundraising while securing additional capital for its operations. The transaction also forms part of the steps being taken by the company towards restoring trading in its shares.
The company is using applicable regulatory exemptions governing public share offers to conduct the retail fundraising. Together with the institutional placing and direct subscription, the structure is designed to maintain participation across management, institutional investors and the existing retail shareholder base.
Windar Photonics continues to face financial and market-related challenges, with weak underlying financial performance and bearish technical indicators weighing on its outlook. Negative valuation metrics add further pressure, while recent strategic and corporate developments provide some positive momentum but have yet to outweigh the company’s broader financial and technical difficulties.
