Northrop Grumman’s first quarter was marked by operational headwinds and financial results that fell short of Wall Street’s expectations, leading to a significant negative market reaction. Management largely attributed the underperformance to delays in government contract awards and a substantial pretax loss from the B-21 bomber program, which resulted from higher manufacturing and material costs as the company scaled up production. CEO Kathy Warden described the financial impact as “disappointing,” but emphasized ongoing progress in testing and production for key programs.

While we enjoy listening to the management's commentary, our favorite part of earnings calls are the analyst questions. Those are unscripted and can often highlight topics that management teams would rather avoid or topics where the answer is complicated. Here is what has caught our attention.

Our Top 5 Analyst Questions Northrop Grumman’s Q1 Earnings Call

• Kristine Liwag (Morgan Stanley) pressed CEO Kathy Warden for clarity on B-21 program risks and the potential for further charges due to tariffs. Warden explained that most cost risks are now reflected but acknowledged ongoing macroeconomic pressures.
• Ronald Epstein (Bank of America) asked if B-21 charges might recur in future years. Warden stated the process changes are complete, reducing future risk, but did not rule out additional inflation-driven impacts.
• Sheila Kahyaoglu (Jefferies) inquired about tariff impacts and Mission Systems profitability. CFO Ken Crews noted most tariff-related costs are managed contractually and predicted Mission Systems margins would improve as higher-margin programs ramp up.
• Myles Walton (Wolfe Research) questioned confidence in the expected second-half sales ramp despite Q1 delays. Crews cited existing backlog, anticipated contract awards, and material timing as reasons for the growth outlook.
• Ken Herbert (RBC Capital Markets) asked about international sales momentum and F-35 production assumptions. Warden highlighted broad-based international demand and confirmed no change in F-35 production expectations.

Catalysts in Upcoming Quarters

In the coming quarters, our analyst team will closely monitor (1) the pace at which delayed U.S. government contracts are awarded and converted into revenue, (2) margin recovery efforts in light of ongoing cost pressures, especially in the B-21 program, and (3) continued expansion in international markets, where sales and bookings momentum will be key to offsetting domestic uncertainties. Execution on key program milestones and new contract wins will also be important indicators.
