The following graph compares the cumulative total returns of LII’s common stock with the cumulative total returns of the Standard & Poor’s 500 Index, a broad index of large U.S. companies of which the Company is a part, and with a revised peer group of U.S. industrial manufacturing and service companies in the HVACR businesses. The graph assumes that $100 was invested on December 31, 2020, with dividends reinvested. Our revised peer group includes AAON, Inc., Carrier Global Corp., CSW Industrials, Inc., Trane Technologies plc, and Watsco, Inc. (“New Peer Group”).
