May 13 (Reuters) - Parcel locker company InPost INPST.AS, target of a takeover offer by a FedEx- and Advent-led consortium, reported first-quarter core profit ahead of market expectations on Wednesday, as growth in Poland and the euro zone helped offset the costs of integrating Yodel in Britain.

Adjusted earnings before interest, taxes, depreciation and amortisation (EBITDA) were 902.2 million zlotys ($249.0 million) in the quarter, above a company-compiled consensus estimate of 856 million zlotys.

InPost's Poland business, still its main profit engine, saw first-quarter delivery volumes rise 8% to 188 million parcels while revenue grew 9.2% to 1.8 billion zlotys. Poland now contributes 47% of the company's revenue, with international markets bringing in a combined 53%.

Yodel integration costs stem mainly from the parcel transformation in Britain following the 2025 acquisition, with focus on cost-per-parcel optimisation, logistics network consolidation and middle-mile efficiency work, InPost said.

InPost handled 359 million parcels in the first quarter, up 32% from a year ago, as Yodel's consolidation led to a 220% surge in the UK and Ireland, while euro zone volumes grew 28% and those of Poland jumped 8%.

It expects mid- to high-teens percentage growth in second-quarter volumes.

The company confirmed its outlook for 2026, aiming to increase its market share with mid- to high-teens growth in processed parcel volumes and mid-teens growth in overall revenue.
