How Platinum Equity still controls McGraw HillMcGraw Hill had 191,276,168 common shares outstanding on June 4, 2026. Platinum affiliated investment vehicles beneficially owned 165,160,216 of them. That majority stake makes McGraw Hill a controlled company under NYSE rules. Platinum can nominate a majority of the board while it owns at least 40% of the outstanding shares. PE Mav Holdings is the record holder named in the ownership table. Stock market access did not shift control away from Platinum. Did Robert Maxwell ever own McGraw Hill?No. Robert Maxwell owned Macmillan, not McGraw Hill. In 1989, McGraw Hill and Macmillan formed theMacmillan/McGraw Hill joint venture. After Maxwell Communications went bankrupt, McGraw Hill bought Macmillan’s share of that venture for $160. 8 million in 1993. The narrow connection is this: Macmillan, while owned by Maxwell’s company, shared one school publishing venture with McGraw Hill. McGraw Hill later bought out Macmillan’s share, so Maxwell was never the owner of McGraw Hill itself. Why McGraw Hill and S&P Global get mixed upThe McGraw Hill name once sat inside a larger public company that also owned Standard & Poor’s, Platts, Capital IQ and other financial data businesses. In 2013, McGraw Hill Financial completed the sale of McGraw Hill Education to Apollo Global Management for$2. 4 billion in cash. The remaining financial data company became McGraw Hill Financial and later S&P Global. S&P Global came from the old parent. It does not own the education company that now trades as MH. How McGraw Hill changed handsThe McGraw Hill brand traces its roots to James H. McGraw and John A. Hill. McGraw bought a railway trade publication in 1888, Hill built a separate publishing business, and the two publishing groups merged in 1917. 1888James H. McGraw buys American Journal of Railway Appliances. 1917The McGraw and Hill publishing companies merge. 1966The broader McGraw Hill company buys Standard & Poor’s. 2013Apollo buys the education business for $2. 4 billion in cash. 2021Platinum Equity completes the McGraw Hill acquisition for about $4. 5 billion. 2025McGraw Hill prices its IPO at$17. 00 per sharefor 24,390,000 shares, or about $415 million before expenses. The IPO returned McGraw Hill to public trading. It also left Platinum with a large majority position. What Platinum controls todayPlatinum’s public case for buying McGraw Hill centered on digital learning and expansion: McGraw Hill was positioned for thecontinued shift to digital, had room for growth and innovation, and could expand through complementary acquisitions and international markets. Platinum was buying more than a textbook name. McGraw Hill sells curriculum, digital courseware, adaptive learning tools, professional medical content and education software. For fiscal 2026, McGraw Hill reported $2. 10 billion in revenue across K-12, higher education, professional and international markets. Platinum’s stake covers that operating education and software business, beyond the textbook imprint many readers know. Who runs McGraw Hill day to day?Philip Moyer became McGraw Hill’s president and chief executive on February 9, 2026, under aCEO succession plan. Simon Allen retired as chief executive and remained board chairman. Platinum controls shareholder votes and board nominations. Moyer and his executive team run the education business day to day. Is McGraw Hill publicly traded?Yes. McGraw Hill became a public company in July 2025 and trades on the NYSE as MH. The public market owns the smaller slice. Exchange trading gives investors access to MH shares while Platinum keeps company control. As of June 4, 2026, the ownership answer is Platinum Equity control through affiliated investment vehicles, with PE Mav Holdings as record holder and public investors holding a minority. Robert Maxwell and S&P Global explain two common ownership confusions, and neither is McGraw Hill’s current owner.
