GE Aerospace shares barely budged Tuesday after the jet-engine maker flagged a possible durability problem with a seal on its GE9X engine, which powers Boeing’s long-delayed 777X. The stock inched up 0.04% to $308.83 by 12:59 p.m. EST, fluctuating between $306.73 and $312.40 earlier. Boeing has already booked over $15 billion in charges tied to the 777X and still aims for first deliveries in 2027.
