Total Fundraise of US$40 million

Result of Retail Offer and Restoration of Trading

Savannah, the developer of the Barroso Lithium Project in Portugal, a 'Strategic Project' under the European Critical Raw Materials Act and Europe's largest spodumene lithium deposit, announced on 22 September 2026 the launch of a fundraising comprising a Placing and Subscription in conjunction with a Retail Offer.

The Company is pleased to announce that the Retail Offer successfully completed and closed at 5.00 p.m. on 24 September 2026 and that it has conditionally raised £2,192,628 in the Retail Offer through the issue of 39,865,966 new Ordinary Shares at the Issue Price of 5.5 pence per share.

As a result of the Retail Offer, substantial shareholders, AMG Lithium B.V. and Telmory LDA have subscribed for 8,937,380 and 5,741,429 additional Subscription Shares respectively to ensure their percentage shareholdings in the Company are maintained on completion of the Fundraise. Further subscriptions have also been received from other parties including £20,000 from Rick Anthon, the Company’s Chair, altogether resulting in 17,562,356 additional Subscription Shares, bringing the total number of Subscription Shares to 189,660,099conditionally raising approximately £10,431,305 via the Subscription.

Following the close of the Placing, the Retail Offer and the Subscription, the Company has conditionally raised gross proceeds of £30,088,587 (US$40,225,384) at the Issue Price via the Fundraising. The Company will therefore be required to issue and allot a total of 547,065,215 new Ordinary Shares to satisfy the aggregate demand of the Fundraise.

Savannah's Chief Executive Officer, Emanuel Proença said:"The level of interest shown in the Fundraise by hundreds of new and existing private investors through the Retail Offer is great to see and all at Savannah are extremely grateful for this support. The diversity in our shareholder base, from large institutions to private shareholders, spread across multiple countries demonstrates the wide levels of interest that exist in the development of the Barroso Lithium Project. The Savannah team and I are committed to creating further value for all our shareholders through the delivery of this exciting Project.

"The US$2.9 million invested through the Retail Offer takes total gross proceeds from the Fundraise to US$40.2 million. These funds, coupled with our existing cash and short term treasuries, give Savannah reserves of over US$53.0 million providing the financial strength to move with even greater purpose towards the start of construction next year."
