Former Qualcomm chief Steve Mollenkopf will make his first public appearance as chairman at the virtual gathering. Boeing is dealing with a sprawling crisis that includes multiple investigations, possible prosecution for past actions and slumping production of its strongest-selling jet. Mollenkopf is leading the search to replace Calhoun, who said he would retire by year-end as part of a management shakeup following a January mid-air blowout on a new 737 MAX 9.
