ISSUE OF SUPPLEMENTARY PROSPECTUS

Further to the announcement made by Northern 3 VCT PLC (“the Company”) on 8 December 2025 in conjunction with Northern Venture Trust PLC and Northern 2 VCT PLC, in respect of the offers of new ordinary shares for subscription in the 2025/26 tax year, the Company has today published a supplementary prospectus (the "Supplementary Prospectus").

The Supplementary Prospectus refers to the increase in the size of its offer (inclusive of already-utilised over-allotment facilities) from £20 million to £30 million in the 2025/2026 tax year (the “Company’s Offer”).

Applications for new shares in the Company will be dealt with on a “first-come, first-served” basis. In recognition of the loyalty of the Northern VCT shareholders, existing shareholders on the register of members of any of the Northern VCTs as at 16 June 2025, along with their spouse or civil partner, whose applications for shares in any of the Northern VCTs are accepted, will benefit from a reduction of 0.5% in the offer costs applicable to their subscription. The Company’s Offer will remain open until 12 noon on 31 March 2026, unless fully subscribed at an earlier date and subject to the Directors’ right to close the Company’s Offer at any time.

The Supplementary Prospectus has been approved by the Financial Conduct Authority and a copy will shortly be available for inspection at the National Storage Mechanism.
