12:48 PM EDT, 09/13/2024 (MT Newswires) -- Moody's Ratings said Friday it has placed all of Boeing's ( BA ) ratings on review for downgrade following the start of a strike earlier in the day by the company's aircraft mechanics and assemblers.

The ratings agency said it will evaluate the duration of the strike, its impact on Boeing's ( BA ) cash flow and whether the company will undertake any equity capital raising to enhance its liquidity. Moody's also said it will assess the extent to which the strike and ongoing production challenges of Boeing's ( BA ) 737 and 787 aircraft impact the timing of production growth rates and the scale and pace of improvements to the planemaker's cash flow. The ratings agency added it will weigh the costs for the company to complete the fixed-price contracts in its defense business.

"A prolonged strike would fracture the recovery of the Commercial Airplanes business, which remains in its early stages," Moody's said.

Boeing ( BA ) did not immediately reply to a request for comment from MT Newswires.

BA shares were down 4% in recent trading.
