Global chip shortage will slash Ford’s production by about half in the second quarter.

Ford Motor said on Wednesday that the global shortage of computer chips will take a greater toll on its business than previously expected and would likely cut its vehicle production in the second quarter by about half.

“The effects of the shortage have grown,” Ford’s chief financial officer, John Lawler, said during a conference call with reporters. “We now expect the semiconductor shortage to get worse and bottom out in the second quarter but continue to put pressure on our operating results in the second half of the year.”

Ford expects the shortage to lower its operating profit this year by $2.5 billion, to between $5.5 billion to $6.5 billion. It had previously said the impact of the shortage would be between $1 billion to $2.5 billion.

The shortage was exacerbated in March by a fire at a plant owned by a Japanese electronics supplier, Renesas.

The grim outlook was delivered as part of a strong earnings report by Ford. The company made a $3.3 billion profit in the first quarter, a turnaround from a year ago when the company lost $2 billion as the coronavirus pandemic was starting to shut down much of the world’s economy.

“There’s no question, we’re becoming a stronger, more resilient company,” Ford’s chief executive, James Farley, said in a statement.

The shortage of computer chips has forced automakers to idle factories around the world. Ford said it produced about 200,000 fewer vehicles than originally planned in the first quarter. But the ability to command higher prices helped Ford’s bottom line, as did lower warranty costs and a $900 million gain related to its stake in Rivian, an electric vehicle start-up.

While it hopes to be able to make up some of the lost production later in the year, Ford will likely produce 1.1 million fewer vehicles in 2021 than it had planned to, Mr. Lawler said.

Ford has been trying to streamline its operations and raise its profits for several years with modest success until now. In 2020, it named Mr. Farley to the top job, charging him with accelerating the turnaround.

The automaker has developed vehicles that could revitalize profits. It redesigned its F-150 pickup truck, the top-selling vehicle in the United States. It has also gotten strong reviews for a new Bronco sport-utility vehicle and the Mustang Mach E, an electric S.U.V. styled to resemble the company’s famous sports car.

But the chip shortage has crimped its plans. In the first three months of the year, Ford has had to pause or slow production at a variety of plants, including some that make the F-150, which generates a large chunk of its profits.
