Boeing said on Wednesday that it was making progress toward increasing production of its commercial planes and stabilizing its business after a quality crisis last year, but the company is facing new threats of disruption from President Trump’s trade war.

Boeing said it lost $31 million in the first three months of this year, a smaller loss than analysts had expected. In the same quarter last year, the company lost more than $350 million.

Boeing’s most recent crisis began when a poorly installed panel blew away from a relatively new Boeing plane during a flight in January 2024. A two-month worker strike in the fall also stalled production of the 737 Max, Boeing’s best-selling plane.

The company has delivered 130 planes in the first quarter, up from 83 in the same period a year ago. It also made progress elsewhere, including securing a major contract to build the Air Force’s newest fighter jet, the F-47, Boeing’s chief executive, Kelly Ortberg, said in a message to employees. Boeing brought in $19.5 billion in revenue during the quarter, an 18 percent rise from last year.

“From delivering more airplanes to scoring a transformational win for the fighter of the future, there is a lot of good work happening across our teams, and we are seeing positive results,” Mr. Ortberg said.

Boeing’s share price jumped in premarket trading, gaining more than 4 percent.

Revenue at Boeing’s commercial unit was up 75 percent in the first quarter, compared with a year earlier, while its defense unit saw a 9 percent fall. Sales at its services unit, which has the biggest profit margins, were flat.
