Tirlán has announced its financial results for 2025, recording an increase in revenue of 10% to €2.94 billion.

The co-ops operating profit for last year stood at €63.7 million, which it said was within its target range.

Tirlán closed the year with core net debt of €126 million, which it said was down on €138 million last year, and which was its lowest figure in over a decade.

The business said its milk collections increased by 7% last year, while milk solids increased by 9%.

In 2025, Tirlán spun-out 15 million Glanbia plc shares worth €253 million, based on Glanbia plc share price as of April 2; and paid €9 million in co-op dividends.

Growth occurred across its three categories of agribusiness, consumer and ingredients.

According to Tirlán, it processed around one-third of Ireland's milk pool last year, with 3.2 billion litres processed.

Its average milk price for 2025 was 54.4c/L, compared to 52c/L in 2024.

The business also took in 234,000t of green grain last year, paying out a total of €1.8 billion in both milk and grain cheques.

According to Tirlán, almost half of the green grain it received qualified for premium payments.

2025 also saw the close-out of the co-op's exchangeable bond, which it said concluded the strategic financing 'journey' that funded the purchase of the Glanbia Ireland processing business and the subsequent establishment of Tirlán.

The co-op retains a 17.9% shareholding in Glanbia plc, valued at €734 million.

Tirlán said that, since 2012, 63 million Glanbia plc shares have been distributed to members.

The business said that its Avonmore brand saw a strong retail performance in 2025, supported by "protein led-innovation".

Tirlán saw sales of 415,000t of dairy ingredients to international markets, with revenue in that category up 13%, despite "particularly challenging market conditions in the fourth quarter of the year".

Other developments Tirlán cited for 2025 included its €15 million Generational Renewal Programme; a €5 million TB Support Programme; and a €126 million investment at its Ballyragget plant in Co. Kilkenny to expand capacity in whey protein ingredients.

Tirlán said that the Generational Renewal Programme, which pays new entrants a 2c/L bonus on all milk supplied in the first three years of production, has proven successful, with 52 new entrants expected this year, a "near record annual number".

Acknowledging a key sector-wide development in 2025, Tirlán said the extension of the nitrates derogation for a further three years, which was confirmed in December, was a "crucial outcome for the viability of family farms and the continuation of sustainable, grass-based food production".

Commenting on the publication of Tirlán's annual results for 2025, co-op chairperson John Murphy said: "This performance was achieved on the back of excellent supply volumes, alongside disciplined cost and cash management."

On the derogation, Murphy thanked farmers for their "ongoing efforts to protect and enhance water quality".

He said that this work "must continue with a sustained focus on reducing nutrient losses from all sources, including agriculture".
