Check out the companies making headlines before the stock market opens. Boeing — The airplane maker slipped slipped 1.3% after preliminary fourth-quarter financial results reflected ongoing struggles. Boeing said it expects to report a loss of $5.46 per share for the fourth quarter on revenue of $15.2 billion, less than analysts’ expectations, according to LSEG estimates. Boeing, which has not posted an annual profit since 2018, said it likely burned through $3.5 billion in cash during the quarter, partly due to a labor strike and new workforce agreement.

Baird upgraded the stock to an outperform from neutral and said it came away from the company’s event confident ahead of its fourth-quarter results. CSX — The Jacksonville, Fla. – based railroad slipped 3.5% after saying revenue fell last quarter due to a lower fuel surcharge and smaller coal revenue.
