The sale of 12m shares in Glanbia by Tirlán has resulted in proceeds of approximately €257.6m for the co-op.

The shares were sold at €21.47 each, which is lower than the price the shares closed at on the stock market the day the sale was announced.

It is usual for there to be a discount when a large number of shares are sold together.

Glanbia used its share buyback scheme to purchase €50m of the shares on offer, with the balance bought by institutional investors.

Following the transaction, Tirlán holds 31.5m shares in Glanbia worth just below €700m at today’s market price.

Chair of the co-op Ger O’Brien said: “It is the board’s intention to re-invest the funds raised, over time, in the longer-term best interests of the co-op,” adding that “we retain strong confidence in Glanbia plc’s strategy, performance and future outlook, and we remain its largest shareholder.”

Diversified investment portfolio

O’Brien did not go into any specifics about how Tirlán would invest the money raised.

The statement announcing the sale said the transaction is a step towards having a more diversified investment portfolio.

Shares in Glanbia have risen more than 50% so far in 2026, and are more than 70% higher than they were a year ago.

In October 2025, Tirlán sold 17m shares in Glanbia to settle an outstanding bond.

That sale of shares completed at €13.55, raising €230m.
