Invinity Energy Systems: Proposed Fundraise and Capital Access Window

· Issued by Invinity Energy Systems PLC via RNS

Summary by 6ix AI

Invinity Energy Systems plc, a maker of vanadium flow batteries for energy storage, intends to raise minimum gross proceeds of approximately £20.0 million through a subscription and an institutional placing at 10 pence per new ordinary share. It also intends to launch a separate retail offer at the same price.

Key details

  • Invinity's ordinary shares entered a Capital Access Window as at 7.30 a.m. on October 19, 2026, and trading in them is temporarily suspended. This is a voluntary trading pause allowed under the AIM Rules for Companies (the rules of the stock market where the shares are listed), meant to make it easier to reach a broader range of investors during a fundraise.
  • The company says it has received indications of interest from existing shareholders and potential new investors to support the subscription and placing.
  • The placing is being arranged by Canaccord Genuity Limited, Panmure Liberum Limited and VSA Capital Limited as joint bookrunners (the banks managing the share sale).

What’s still pending

  • Completion of the fundraise is subject to, among other things, shareholder approval at a general meeting. Notice of the meeting will be in a shareholder circular sent after the fundraise is finalised.
  • The company expects to announce the details of the fundraise, including its terms and conditions, at a later point.
  • The trading pause will last until the fundraise concludes, after which trading is expected to be restored.

Proposed Fundraise and Capital Access Window

Invinity Energy Systems plc (AIM: IES), a global leader in vanadium flow battery (“VFB”) technology, is pleased to announce its intention to undertake a subscription (the “Subscription”) and an institutional placing (the “Placing”) to raise, in aggregate, minimum gross proceeds of approximately £20.0 million.

Alongside the Subscription and Placing, the Company also intends to launch a separate retail offer (the "Retail Offer") (together with the Subscription and Placing, the “Proposed Fundraise”). The Proposed Fundraise will all be conducted at an issue price of 10 pence per new ordinary share.

The Company has received strong indications of interest from existing shareholders and potential new investors to support the Subscription and Placing.

Completion of the Proposed Fundraise will be subject to, among other things, shareholder approval at a General Meeting of the Company. Notice of the General Meeting will be included in a shareholder circular, which will be posted to shareholders after the Proposed Fundraise has been finalised.

Capital Access Window

The Company has decided to utilise a Capital Access Window for the Proposed Fundraise. The Capital Access Window is a voluntary pause in trading of a company's shares permitted under the AIM Rules for Companies, designed to make it easier for companies to reach a broader range of investors during a fundraise.

Accordingly, the Company's ordinary shares will enter a Capital Access Window as at 7.30 a.m. today and trading in the ordinary shares will be temporarily suspended. The Company expects to announce the details of the Proposed Fundraise, including the terms and conditions, in due course. The Capital Access Window will remain open until the conclusion of the Proposed Fundraise, after which trading in the ordinary shares is expected to be restored.

The Placing is being arranged by Canaccord Genuity Limited, Panmure Liberum Limited and VSA Capital Limited (the “Joint Bookrunners”).

This announcement does not constitute an offer of securities in any jurisdiction. Further announcements will be made as and when appropriate.
