Meanwhile, Congress has vowed to investigate the cause of the crashes. And families of at least two dozen crash victims are suing the company.
Fighting to stem the fallout from the crashes, Muilenburg called President Donald Trump Tuesday, vowing that the planes were safe and that there was no reason to ground them. Eventually, the Federal Aviation decided to do so anyway.
"The safety of the American people, and all our people, is our paramount concern," Trump said in explaining his decision.
Still, analysts have said the crisis is unlikely to have a long-term effect on the company's finances. Despite the crash in October last year, the company finished 2018 with record revenue that beat its goal, profit of $10 billion and a healthy order book for future growth.
In 2017, Boeing's stock climbed nearly 90 per cent, and for the first two months this year, it was up nearly 35 per cent.
In the SEC filing, Boeing's compensation model for its executives is "designed to drive near-term program execution, operational excellence and sustainable growth." By those measures, Boeing's CEO had a banner year, the filing said.
"Mr. Muilenburg's leadership in successfully executing Boeing's business strategies in 2018, as evidenced by record operating cash flow, revenue, operating earnings and commercial airplane deliveries," it said.
