GE Aerospace (NYSE: GE) shares jumped 5.10% in pre-market trading on Tuesday after the jet engine maker reported first-quarter earnings that surpassed analyst expectations and reaffirmed its full-year outlook despite tariff headwinds.

The company posted adjusted earnings per share of $1.49 for the quarter, significantly beating the $1.27 consensus estimate. Revenue climbed 11% year-over-year to $9.94 billion, also topping analysts' projections of $9.05 billion. The strong performance was driven by robust demand in GE's commercial engines and services segment, which saw revenues rise 14.5% to $6.98 billion.

Despite concerns over the impact of recently announced tariffs, GE Aerospace maintained its 2025 guidance. The company continues to expect adjusted earnings per share of $5.10 to $5.45 and low double-digit revenue growth for the full year. Management stated that the outlook now incorporates the effects of announced tariffs, net of mitigating actions being taken.

"GE Aerospace had a strong start to 2025 with orders and revenue up double digits, driven by commercial services, and adjusted EPS up 60%. We continue to drive improvements through FLIGHT DECK, tackling supply chain constraints head on to accelerate deliveries throughout 2025," said GE Aerospace Chairman and CEO H. Lawrence Culp, Jr. in a statement.

The company is benefiting from a favorable market environment where ongoing production setbacks at major aircraft manufacturers have extended delivery timelines for new planes. This has prompted airlines to rely more heavily on older fleets that require frequent maintenance, driving demand for GE's high-margin aftermarket parts and services.
