Its profit amounted to 402 million Swiss francs (about 415 million euros) against 460 million in the first half of last year.
In the first half, sales of the group, which manufactures showers, toilets and bathroom equipment, were quite good, at 1,9 billion Swiss francs, an increase of 5,5%.
But inflation has pushed up its costs: "sales price adjustments can only be made with a delay, which means that it has not been possible to fully compensate for the increase in the price of raw materials and energy over the period," Geberit said in its press release.
For the third quarter, Geberit expects costs to rise further with inflation, which should lead to further price increases.
In addition, the group, which sells a large part of its products in Europe, particularly in Germany, was affected by the rise in the Swiss franc against the euro, a negative impact estimated at 106 million Swiss francs.
Geberit, which had taken advantage of the consumer enthusiasm for home furnishings and renovation during the pandemic, is seeing this trend decline, particularly in France.
Geberit's operating margin was chipped away from almost 30% in the first half of 2021 to 25% in the first half of 2022.
For the rest of the year Geberit expects "single-digit growth" in sales and an Ebitda margin (operating profitability without taking into account calculated expenses) at 28%.
Geberit had suspended its activities in Ukraine and Russia in March after the outbreak of the war: it employed some 590 people in Ukraine and 70 people in Russia.
