Shares of RTX (RTX) slumped Tuesday as the defense contractor warned new Trump administration tariffs will impact results. Rival Northrop Grumman (NOC)'s stock also dropped sharply on costs related to the B-21 bomber. Shares of Lockheed Martin (LMT) fell, too, even though the comp𒉰any's results topped estimates as it benefited from higher demand for its weapons.

RTX, whose shares sank 9% soon after the opening bell, said if the tariffs last the year, it may see a negative impact on 澳洲幸运5开奖号码历史查询:operating profit of more than three-quarters of a billion dollars. It sees $250 million drops because of levies on Canada and Mexico, plus another $250 million hit from those on China and from China. Global reciprocal tariffs could cause an additional $300 million decline, and steel and aluminum tariffs would add another $50 million.

Northrop Grumman, whose shares dropped 12% to lead early 澳洲幸运5开奖号码历史查询:S&P 500 decliners, reported first-quarter profit slumped 47% year-over-year, with 澳洲幸运5开奖号码历史查询:earnings per share (EPS) of $3.32 nearly 50% below estimates of analysts surveyed by Visible Alpha. Sales sank 7% to $9.47 billion, also short of forecasts.

The company blamed the weak results on a pre-tax loss of $477 million ($397 million after-tax or $2.74 per diluted share) because of five low-rate initial production (LRIP) options related to the B-21 program. It noted the slide was primarily caused by "a process change made by the company to enable an accelerated production ramp, as well as increases in the projected cost and quantity of general procurement materials."

However, Lockheed Martin posted EPS of $7.28 on revenue that rose 4.5% to $17.96 billion, with both exceeding forecasts. The company's Aeronautics division, which makes the F-35 fighter, reported a sales gain of 3% to $7.06 billion.

Both Lockheed Martin and RTX affirmed their full-year outlooks, although RTX’s guidance didn’t incorporate more recent tariffs.
