• No Proceeds to the Company

  All shares are being sold by the selling stockholder; McGraw Hill will not receive any proceeds from the sale.

Platinum Equity, the controlling stockholder with 86.3% of McGraw Hill's outstanding shares, has filed a shelf registration to sell up to 165.2 million shares — essentially its entire position. The registration does not mean a sale is imminent, but it clears the way for Platinum to exit completely over time. At the proposed maximum offering price of $9.265 per share, the total offering could reach $1.53 billion. McGraw Hill receives no proceeds; all shares are being sold by the selling stockholder. For a company that just returned to profitability and announced a $50 million buyback, the overhang of a potential control-block liquidation is a significant market-moving event.
