May 6 (Reuters) – Danish wind turbine maker Vestas reported an unexpectedly large first-quarter profit rise on Wednesday as it ramped up production for the ‌offshore sector, but warned of geopolitical and tariff-related risks.

“Last year in Q1 we ‌hadn’t put a single one of our new offshore turbines up,” Vestas Chief Financial Officer Jakob Wegge Larsen ​told Reuters in an interview.

“What we really see in Q1, in the revenue increase, is that the offshore ramp-up is progressing positively. We are now installing and manufacturing offshore turbines at a significantly higher level compared to last year,” he added.

Shares in Vestas were 1.5% higher at ‌0849 GMT, helping their year-to-date gain ⁠to 13.4%.

Vestas has been aiming to sell more to offshore power developers, but high costs have held back manufacturing. After struggling with supply ⁠chain disruptions, high offshore ramp-up costs and other cost inflation, it is now seeking to boost margins despite U.S. wind policy and tariff uncertainty.

The Danish company repeated guidance from February for a full-year ​operating ​margin before special items of 6% to 8% ​on sales of between 20 billion ‌and 22 billion euros. In 2025, the margin was 5.7% on sales of 18.8 billion euros.

Vestas said the outlook forecast was based on the assumption that the geopolitical environment does not significantly change business conditions.

“We achieved the highest first-quarter profitability since 2018,” said Vestas CEO Henrik Andersen in a statement, adding that geopolitical uncertainty and the energy crisis “underline the need for ‌affordable, secure, and sustainable energy”.

Vestas reported an increase ​in order intake, to 4.50 gigawatts (GW) from 3.14 GW, ​although this was slightly less than analysts ​had expected.

In the first quarter, operating profit before special items was ‌127 million euros ($149 million) against a year-earlier ​14 million and a ​mean forecast of 71 million in an analyst poll shared by Vestas. The margin widened to 3.2%.

Turnover in the quarter, the sector’s seasonally slowest, increased 14% to 3.97 ​billion euros, slightly above expectations, ‌as sales of offshore turbines picked up.

Vestas also announced a new 100 million ​euro share buyback programme.
