Statement on Tirlán Equity Placement and Off Market Purchase

Glanbia plc, the Better Nutrition company ("Glanbia" or the "Company"), has been informed by Tirlán Co-operative Society Limited ("Tirlán") that it intends to sell approximately 12 million ordinary shares in the capital of Glanbia by way of:

1.   a private placement to institutional investors to be executed through an accelerated bookbuild offering process (the "Equity Placement"); and

2.   an off-market sale by Tirlán to the Company of shares up to an aggregate value of EUR 50 million (the "Off Market Purchase"") pursuant to the directed buyback contract (the "Directed Buyback Contract") between the Company and Tirlán approved by shareholders at the annual general meeting of the Company held on 29 April 2026 (the "2026 AGM"),

(together, the "Transaction").

The Off-Market Purchase will be conducted within the limits of the Company's authority to repurchase shares off market, as set out in Resolution 13 approved by shareholders at the 2026 AGM, in conjunction with, and conditional upon, the completion of the Equity Placement. Any shares purchased by the Company pursuant to the Directed Buyback Contract will be cancelled.

The consideration for the Off-Market Purchase will, in accordance with the Directed Buyback Contract, be determined by reference to the price established through the bookbuilding process in the Equity Placement.

The shares subject to the Transaction represent approximately 5.00% of Glanbia's issued share capital.

On 25 February 2026, the Company announced that the Board had approved a €100 million share buyback programme, of which €50 million was commenced on the same date. The €50 million programme which commenced on 25 February 2026 remains ongoing. The Off-Market Purchase will utilise the remaining €50 million of the authorised €100 million buyback programme.

Goodbody Stockbrokers UC ("Goodbody") and Coöperatieve Rabobank U.A. in cooperation with Kepler Cheuvreux S.A. ("Rabobank-Kepler Cheuvreux") are acting as joint global coordinators and joint bookrunners in connection with the Equity Placement (Goodbody and Rabobank-Kepler Cheuvreux together the "Joint Global Coordinators").

The Company confirms that it currently has no unpublished inside information.

Further details of the Off-Market Purchase, including the number of shares acquired and the price per share, will be published following completion of the Transaction.
