01:37 PM EDT, 06/11/2024 (MT Newswires) -- Boeing ( BA ) on Tuesday posted lower deliveries and orders for May from a year earlier, sending the plane maker's stock slumping.

The company delivered 24 jets last month, including 19 737 Max aircraft. May's total deliveries matched the previous month's tally, but were down from 50 a year earlier, according to data posted on the company's website.

Boeing ( BA ) booked four gross orders last month, down from seven in April and 69 a year earlier. The company didn't book any orders for its best-selling 737 Max jet for the second consecutive month, the data showed.

Boeing ( BA ) shares were down 2.9% in afternoon trading.

In April, the company logged an unexpected narrower first-quarter loss, while revenue declined annually. The company said at the time it reduced output of its 737 program to below 38 planes per month to implement quality management system improvements and ease traveled work within its factory and supply chain.

In January, the US Federal Aviation Administration launched an investigation into Boeing ( BA ) after a 737 Max 9 operated by Alaska Air ( ALK ) suffered a mid-air panel blowout.

So far in 2024, Boeing ( BA ) has delivered 131 jetliners and booked 142 gross orders. As of May 31, it had 6,188 unfilled orders, the data showed.

Earlier this month, Boeing's ( BA ) European rival Airbus said it delivered 53 aircraft in May, bringing its 2024 total so far to 256, while its gross orders reached 27 last month.

The companies' order activity is likely to get a boost from next month's Farnborough Airshow, Truist Securities said in a Tuesday note. However, "weak" original equipment manufacturer delivery activity is expected to persist in the coming months, the brokerage said. "The weak deliveries, specifically on the narrow-body side, will likely to be an area of investor focus into (the second-quarter) earnings season."
