Shares in PTSB have notched up the biggest gain of any company on the Euronext Dublin’s Iseq 20, having risen 112pc so far in 2025. They were boosted as the bank put itself up for sale in October, with the announcement sending its shares 23pc higher.

PTSB, whose chief executive is Eamonn Crowley, has said a new owner would support the bank in its next phase of growth. It would also provide a cash windfall for the Exchequer. The State still owns 57pc of the bank, which currently has a near €1.7bn market capitalisation.

Bank of Ireland is the second-best-performing company on the exchange this year. Its shares have climbed 82pc since January 1. In July, the bank reaffirmed its medium-term guidance but saw its pre-tax profit fall by a third to €721m in the first half of the year as it was impacted by lower European Central Bank interest rates and a €137m impairment charge related to a US unit.

Healthcare services group Uniphar is the third-best performer on the exchange, with its shares 72pc higher this year.

AIB is fourth, rising 66pc so far in 2025. The State sold its last remaining stake in AIB during the summer, disposing of 2pc of the bank for €305m.

Shares in Ryanair slip in as the fifth-best performer on the Iseq 20 so far this year, having advanced 44pc. During the year, group chief executive Michael O’Leary saw a more than €100m bonus crystallise.

Food group Greencore, listed in London, has advanced 28pc so far this year, while diversified group DCC, listed on the FTSE100, has fallen 1.5pc

He qualified for the payout after Ryanair stock traded above €21 for a 28th straight day. He stands to eventually receive 10 million shares for €11.12 apiece, or €111.2m in total. Based on the €27.53 closing price on Friday this week, the stock would be worth €275m, making for a paper profit of €164m.

Although no longer listed in Dublin, shares in Ireland’s biggest company, CRH, have advanced 31pc so far this year in New York. The US is the company’s single biggest market and it moved its primary listing to the New York Stock Exchange in 2023.

Food group Greencore, listed in London, has advanced 28pc so far this year, while diversified group DCC, listed on the FTSE100, has fallen 1.5pc.

Shares in Paddy Power and FanDuel owner Flutter Entertainment, have had a torrid year. It moved its primary listing to New York last year.

But the shares have declined more than 18pc this year. Last month, the gambling firm cut its full-year forecasts as customers beat the odds leading to higher payouts by the group.

The biggest decliner so far this year on the Iseq 20 is Kenmare Resources. The mining firm’s shares have fallen 24pc.

It owns the Moma ilmenite mine in Mozambique, one of the largest such mines in the world. Ilmenite is used to make titanium oxide. A takeover approach for Kenmare led by its former boss, Michael Carvill, was rejected by the company’s board in March this year. It valued the group at €565m. The shares are currently trading at €2.90 in Dublin and £2.60 in London, compared with the £5.30 that was being tabled in the approach.
