Boeing Co. shares were down 3.6% to $229.74 after the company said it identified additional rework needed on undelivered 787s, and said 787 production will temporarily be lower than five per month.

Boeing said it has been talking with the U.S. Federal Aviation Administration on verification methodology for 787 fuselages and conducting inspections and rework. The company said it identified additional rework needed on undelivered 787s.

Boeing said it is reprioritizing production resources for a few weeks and the 787 production rate will fall below five per month before gradually returning to that rate. Boeing said it now expects to deliver fewer than half of the 787s currently in inventory this year.

The Wall Street Journal, citing people familiar with the matter, had reported Monday that a new production problem has surfaced with Boeing's 787 Dreamliner, likely further delaying deliveries.

Boeing said Tuesday its 787 deliveries in the second quarter were 12, with 14 year to date. Among its major commercial airplane programs, the company delivered 79 in the quarter and 156 in the year-to-date period.

Vertical Research Partners in a note said it is retaining its Hold rating on the stock.

"While the sub-par delivery number for 2Q21 should come as no surprise to investors, we think that there will be some disappointment about the additional 787 issues, and cut to the delivery/production forecast," Vertical Research Partners said.

"This again gives the impression that Boeing has not got its house in order, and that it is falling further behind as other aerospace companies start to enjoy the early signs of an aerospace recovery," the Vertical Research note said.

"We plan to formally update our Boeing estimates in our 2Q21 earnings preview this week, but the delivery numbers and updated 787 forecast clearly put downward pressure on our numbers," Vertical Research said.
