STUTTGART (dpa-AFX) - The multi-billion dollar costs associated with extending the lifespan of internal combustion engines almost entirely wiped out sports car manufacturer Porsche's profits in 2025. After-tax earnings plummeted by 91.4 percent year-on-year to 310 million euros, according to the Volkswagen Group subsidiary. The dividend is expected to be reduced from 2.31 euros per preferred share to 1.01 euros./jwe/DP/men
