Proxy advisor Glass Lewis has recommended shareholders vote against the reelection of three directors to Boeing’s board, including outgoing CEO Dave Calhoun, citing dissatisfaction over the efforts to transform the safety culture at the planemaker.

Glass Lewis also recommended Boeing shareholders vote to approve top executives’ 2023 compensation, under which CEO Calhoun’s pay package rose about 45% to nearly $33 million. The vote, however, is not binding on Boeing.
