Check out the companies making headlines in midday trading. United Airlines , Boeing — United Airlines tumbled 9%. The action came after the Federal Aviation Administration said it would audit Boeing ‘s production line following the partial blowout of a Boeing 737 Max 9 during an Alaska Airlines flight. Boeing shares slipped 2% on the back of the probe. United said it already found loose hardware on planes of the same type. Delta Air Lines — Shares of the airline slid 8% after Delta trimmed its full-year profit outlook for 2024.

The company also said on Thursday that it would temporarily halt production at its factory in Germany over supply chain constraints stemming from attacks in the Red Sea. CVS Health — Shares slid 2.5% after the pharmacy chain said it was shuttering select pharmacies inside Target stores early this year. CVS didn’t disclose the number of closures, although The Wall Street Journal reported on Thursday that it would be in the “dozens.” UnitedHealth , Humana — The health insurance giant slipped 3.6% after its bottom-line results were pressured by increased medical costs, which management said was seasonal and due in part to Covid.
