Fiat Chrysler Automobiles on Thursday posted a 61 percent gain in fourth-quarter net income to $1.47 billion along with revenue growth of 6 percent to $34.7 billion.
For the full year, FCA's net income rose 3 percent to $4.1 billion.
FCA said its 44,000 UAW-represented workers in the U.S. will receive average profit-sharing payments of $6,000 -- a $500 increase from the year before -- on March 8.
The 2018 profit-sharing payment is based on the company's adjusted earnings performance in North America. FCA said its UAW hourly employees have received more than $29,000 in profit sharing, on average, since 2009.
The company said it invested more than $10 billion and created nearly 30,000 jobs in the U.S. in the last decade.
Meanwhile, FCA shares were down about 10 percent in Europe because the company issued weaker-than-expected guidance for profits and industrial free cash flow for 2019, raising doubts about the automaker's longer-term financial targets. FCA shares in New York were down 9.6 percent in premarket trading to $15.68 as of 8:15 a.m.
The world's seventh-largest carmaker said in the report that it expected 2019 adjusted earnings before interest and tax -- excluding the Magneti Marelli parts unit it has agreed to sell -- of more than $7.6 billion, below analysts' average forecast of about $8.3 billion.
FCA also said it expects industrial free cash flow in 2019 of more than $1.7 billion, which is lower than the $5 billion reached at the end of last year, due to higher capital expenditures along with cash payments for fines and other costs related to its U.S. settlement for diesel emissions infringements.
