Dividend Kings—companies with 50+ years of annual dividend hikes—are rare, but ExxonMobil, NNN REIT, and Medtronic are getting close. ExxonMobil has upped dividends for 42 years, backed by strong growth plans and new energy investments. NNN REIT's simple net-lease model has 36 years of increases, fueled by steady retailer relationships and conservative finances. Medtronic, at 48 years, is restructuring to focus on core business lines, setting up for continued growth. All three have the balance sheet strength to keep raising payouts, making them potential future Dividend Kings.
