- Chief Financial Officer Brian West said the financial impact of the strike will depend on how long it lasts, but noted it will affect the company's production of its bestselling planes.
- Boeing workers overwhelmingly rejected a tentative labor agreement and walked off the job after midnight on Friday.
- The potential production disruption comes as the plane maker has been facing a slew of issues.
Boeing CFO Brian West said the labor strike that began just after midnight Friday will hurt aircraft deliveries and "jeopardize" the company's recovery, hours after factory workers overwhelmingly rejected a new labor contract and walked off the job.
West said the financial impact of the strike will depend on how long it lasts, but that it will affect the company's production of its bestselling planes, including its cash cow bestseller, the 737 Max, which is produced in Renton, Washington.
"The strike will impact production and deliveries and our operations and will jeopardize our recovery," West said at a Morgan Stanley conference on Friday. "So our immediate focus is to the laser-like focus on actions to conserve cash, and we will."
He said Boeing's priority is to get back to the bargaining table and "reach an agreement that's good for our people, their families, our community."

Boeing shares fell sharply on Friday after Moody's put all of Boeing's credit ratings on review for a downgrade and Fitch Ratings said a prolonged strike could put Boeing at risk of a downgrade, actions that could drive up the borrowing costs of a manufacturer that already has mounting debt.

Boeing shares closed nearly 4% lower Friday.
West declined to say whether the company could meet a rate of producing 38 737 Max planes per month by the end of the year.
Jefferies aerospace analyst Sheila Kahyaoglu had previously estimated that a 30-day strike could be a $1.5 billion hit for Boeing.
West said Boeing's immediate focus would be "on actions to conserve cash" and added that new CEO Kelly Ortberg would be working to restore relationships with the union.
Boeing and the International Association of Machinists and Aerospace Workers had unveiled a tentative labor agreement on Sunday that included 25% wage increases over four years and other improvements to health-care and retirement benefits. But workers had been looking for raises of 40% and argued that it didn't cover the increased cost of living.
Workers in the Seattle area and in Oregon voted 94.6% to reject the proposal, and 96% voted in favor of a strike.
They walked off the job after midnight on Friday.
Boeing machinists last went on strike in 2008, a work stoppage that lasted nearly two months.
The potential production disruption comes as the manufacturer has been facing a slew of issues. It's struggled to ramp up production and restore its reputation following safety crises.
A door plug blowout on a nearly new Boeing 737 Max 9 in January led the Federal Aviation Administration to bar Boeing from increasing output of its Max planes and the FAA to boost inspections at production plants, until the regulator is satisfied with its safety and quality procedures there.
An FAA spokeswoman told CNBC on Friday that the agency will keep its inspectors at Boeing facilities during the strike.
