By Christoph Steitz FRANKFURT (Reuters) -German luxury sports car maker Porsche slashed a series of forecasts for 2025, hit by weakness in its main market, China, rising supply chain costs and U.S. tariffs that are disrupting the global car industry.

Porsche AG expects its profit margin to slip into single digits this year, with the luxury-car maker warning about US tariffs and higher costs from weak electric-vehicle adoption.

The premium sports-car maker cut its sales and profitability guidance for the year due in part to a hit from U.S. import tariffs.
