May 5 - Huntington Ingalls, the U.S. military shipbuilder, reported a decline in its first-quarter operating margin as elevated costs and trade volatility eroded profitability.
The company said its overall operating margin slipped to 5.0% from 5.9% a year earlier. Quarterly earnings per share held steady at $3.79, while total revenue for the quarter reached $3.1 billion, outpacing Wall Street expectations of $3.02 billion based on data compiled by LSEG.
Management pointed to rising input costs and broader market uncertainty as key drags on profitability. The overall cost of product sales rose 20% to $1.74 billion, a jump that the company said contributed materially to the margin decline.
Segment performance and drivers
Newport News, Huntington Ingalls' shipbuilding business, reported a notable increase in sales for the quarter ending March 31. Sales at the Newport News yard rose 19.3% to $1.67 billion. Despite that top-line growth, the segment's operating margin tightened by 80 basis points to 5.3%.
Company commentary pointed to the combined effect of inflationary pressures and volatility in global trade as factors that have deepened strain on supply chains across sectors, including defense. The report noted that U.S. tariffs on major trading partners have added to market uncertainty and further stressed supply chains.
Market reaction and demand context
Shares of Huntington Ingalls were down nearly 3% in premarket trading following the results. The company continues to face mounting cost pressures even as demand for large naval platforms remains robust. Huntington highlighted continued strong U.S. demand for submarines and aircraft carriers amid concerns over China’s growing naval presence and broader geopolitical tensions.
While revenue outperformed estimates and EPS remained flat, the combination of higher product costs and compressed margins underscores the near-term profitability challenges the shipbuilder faces.
Outlook considerations
The company’s results emphasize the tension between robust defense demand and near-term cost inflation. Huntington Ingalls' ability to manage supply-chain disruptions and cost increases will be central to restoring margin levels in subsequent periods.
