Should L3Harris Stock Holders Look At Lockheed Martin Instead?

L3Harris (LHX) and Lockheed Martin (LMT) benefit from missile production demand. LMT raised 2026 revenue and free cash flow forecasts, while LHX increased revenue and EPS forecasts but cut 2028 cash flow. LMT trades at a lower P/E and has less debt. LHX has higher net margins and longer-term growth. Both are investing in missile capacity, with LMT securing a $4.7B contract with LHX.
