PrimaryBid Offer

Big Yellow (LON: BYG), is pleased to announce a conditional offer for subscription of new ordinary shares of 10 pence each in the capital of the Company ("Ordinary Shares") via PrimaryBid (the "PrimaryBid Offer"). The Company is also conducting a placing of new Ordinary Shares by way of an accelerated bookbuilding process (the "Placing") as announced by the Company earlier today. The issue price of the new Ordinary Shares to be issued pursuant to the PrimaryBid Offer and the Placing will be determined following the close of the bookbuilding process.

The PrimaryBid Offer is conditional on the new Ordinary Shares to be issued pursuant to the PrimaryBid Offer and the Placing being admitted to the premium listing segment of the Official List of the Financial Conduct Authority and admitted to trading on the main market for listed securities of London Stock Exchange plc ("Admission"). Admission is expected to take place at 8.00 a.m. on 13 October 2023. The PrimaryBid Offer will not be completed without the Placing also being completed.

The Company will use the gross proceeds to build out the Group's existing pipeline of stores.

Reason for the PrimaryBid Offer

While the Placing has been structured as a non-pre-emptive offer within the Company's existing authorities from shareholders for non-pre-emptive offers so as to minimise cost and time to completion, the Company values its retail investor base and is therefore pleased to provide retail investors with the opportunity to participate in the PrimaryBid Offer in line with the Pre-Emption Group guidelines.

There is a minimum subscription amount of £250 per investor in the PrimaryBid Offer.
