Britain’s competition watchdog has approved Boeing’s planned acquisition of Spirit AeroSystems, ruling out an in-depth probe into potential anti-competitive effects.

The decision is expected to reassure investors following a string of crises that have weakened Boeing’s finances, hurt staff morale, and eroded public confidence.

Boeing did not immediately respond to a request for comment, according to Reuters.

A Spirit spokesperson said the deal is expected to close in the fourth quarter of this year.

The UK’s Competition and Markets Authority gave no further details in its initial statement but confirmed the probe would not proceed to a “phase 2” review, citing available evidence.

It added that the full decision would be published shortly.

Boeing agreed last year to reacquire Spirit in a $4.7 billion all-stock deal aimed at streamlining operations and strengthening quality control, years after spinning off the supplier.

The deal ends nearly two decades of independence for the world’s largest standalone aerostructures manufacturer.
