Lennox (LII) Highlighted as Cash-Rich Buy; Affirm (AFRM), Northern Oil (NOG) Disappoint

StockStory flagged Lennox International (NYSE:LII) as a standout cash-producing stock on June 5, 2026, while casting doubt on Affirm Holdings (NASDAQ:AFRM) and Northern Oil and Gas (NYSE:NOG) due to poor capital allocation. Lennox, the HVACR manufacturer, delivered a trailing 12-month free cash flow margin of 12.8% and effectively converts cash into shareholder value. Its shares trade at $518.13, or 20.7 times forward earnings. Affirm, despite a 19.8% free cash flow margin, fell short in its capital-allocation review. The payments network’s stock sits at $68.40, a 17.7x forward P/E. Northern Oil and Gas, with a 13.8% margin, trades at $21.80 (5.3x forward P/E) but raised concerns over its cash utilization as a non-operating stakeholder in U.S. shale.
