Also on Tuesday, Favre and CEO Patrick Koller issued annual targets at the low end of forecasts, citing caution linked to Chinese lockdowns and the war in Ukraine.
The combined group should generate sales of about 23 billion to 24 billion euros this year with a profit margin of 4 to 5 percent, Faurecia said in its first financial guidance since the Hella deal was sealed in January.
Analysts had on average predicted combined sales of 24 billion euros for 2022 -- a 54 percent jump from Faurecia's revenues last year -- with a profit margin of 6 percent.
The supplier said its guidance was based on cautious estimates on worldwide automotive production, which have been revised down due to global supply disruptions linked to the war in Ukraine and new COVID lockdowns in China.
"Components are not the problem," Favre, who will be chief executive at the Hella division, told journalists in a call.
"The problem is knowing what the final demand will be, and the situation in China, which is both a production and a demand problem," Favre said.
Lockdowns to manage growing COVID-19 flare-ups in the world's largest auto market are stranding workers, shutting factories and clogging up ports, disrupting supply chains already shaken by two years of pandemic and Russia's war on Ukraine.
Favre also noted inflation and continued risks to semiconductor chips supplies, but said shortages in Ukrainian-made wire harnesses, which had hampered production for customers such as Volkswagen and BMW, were being mitigated by back-up production in Romania and North Africa.
