Shares of Northrop Grumman fell roughly 5% on January 7, 2026, following a Truth Social post by former President Donald Trump calling out massive dividends and stock buybacks across the U.S. defense industry. Trading volume spiked to 1.8 times the 30-day average as investors weighed the risk of political pressure on capital allocation priorities. Trump specifically warned that buybacks were occurring “at the expense and detriment of investing in plants and equipment,” flagging potential delays in modernization programs such as the B-21 Raider and next-generation radar systems. Analysts estimate Northrop Grumman repurchased over $4 billion of its own shares in the last four quarters, representing more than 3% of its market capitalization, while allocating $2.7 billion to R&D and capital expenditure. The sell-off reflects growing concern that heightened scrutiny could trigger legislative proposals to limit buybacks or redirect funds toward domestic manufacturing projects under the Department of Defense budget review now underway in Congress.
