Are Benjamin Moore and Sherwin-Williams the same company?

No, Benjamin Moore and Sherwin-Williams are not the same company, they are separate independent paint companies and major competitors, with Benjamin Moore owned by Berkshire Hathaway since 2000 and Sherwin-Williams being independent publicly traded company, though both are leading premium paint brands in US. Benjamin Moore and Co, founded in 1883 in Brooklyn, New York, USA by Benjamin Moore, headquartered in Montvale, New Jersey, is premium paint manufacturer sold through independent retailers, not big box stores, known for high-quality paints like Regal Select, Aura, and Ben, with revenue around 1 to 2 billion dollars, owned by Berkshire Hathaway since Warren Buffett acquired it in 2000 for 1 billion dollars, operating as subsidiary with independent management. Sherwin-Williams Company, founded in 1866 in Cleveland, Ohio, USA by Henry Sherwin and Edward Williams, headquartered in Cleveland, Ohio, is largest paint company in US and world by revenue over 23 billion dollars, publicly traded on NYSE as SHW, owned by shareholders, with over 5,000 company-owned stores and brands including Sherwin-Williams, Valspar, Minwax, sold at Sherwin-Williams stores and Lowe's, with wide range of architectural and industrial coatings. Both are competitors in premium paint market, with Benjamin Moore often considered higher quality for interior by painters, Sherwin-Williams larger with more stores and industrial coatings, but separate companies with different ownership, headquarters, and distribution. So Benjamin Moore and Sherwin-Williams are not same company, they are separate competitors, Benjamin Moore owned by Berkshire Hathaway, Sherwin-Williams public company.
