Item 1 Comment:
Explanatory Note: The common shares (the "Common Shares") of Thomson Reuters Corporation ("Thomson Reuters") that are the subject matter of this Amendment 24 to Schedule 13D are beneficially owned by Thomson Investments Limited, The Woodbridge Company Limited ("Woodbridge"), 1908720 Ontario Limited, 1000706525 Ontario Limited, 1396164 Ontario Limited, 1925124 Ontario Limited, Woodbridge Investments Corporation, KRT Investments Corp., DKRT Family Corp., DKRT Investments Corp., DKRT Funding Corp., 1000920847 Ontario Limited, MB Finance Corp., TT Investments Corp., TLT Investments Corp., TLT Issue Holdco A Corp., TLT Issue Holdco Corp., 1761173 Ontario Limited, 2677295 Ontario Limited, 1000919995 Ontario Limited, 1754693 Ontario Limited, PJT Investments Corp., 1000920848 Ontario Limited, PGF Investments Corp., PGF Family Corp., LCC Investments Corp., 1000078931 Ontario Limited, 1000421133 Ontario Limited, LLD Investments Corp., 2806335 Ontario Limited, JRD Investments Corp., 2754783 Ontario Limited, GED Investments Corp., SEG Investments Corp., 1000031857 Ontario Limited, SEG Family Corp., TCM Investments Corp., DYM Investments Corp., BG Investments Corp., ACG Investments Corp., 1001404651 Ontario Limited and 2808194 Ontario Limited (each a "Reporting Person" and collectively, the "Reporting Persons"). Woodbridge, a private company, is the primary investment vehicle for members of the family of the late Roy H. Thomson, the first Lord Thomson of Fleet. Prior to his death in 2006, Kenneth R. Thomson controlled Thomson Reuters through Woodbridge. He did so by holding shares of a holding company of Woodbridge, Thomson Investments Limited. Under his estate arrangements, the 2003 TIL Settlement, a trust of which The Bank of Nova Scotia Trust Company (the "Trust Company") is trustee and members of the family of the late first Lord Thomson of Fleet are beneficiaries, holds those holding company shares. Kenneth R. Thomson established these arrangements to provide for long-term stability of the business of Woodbridge. The equity of Woodbridge continues to be owned by members of successive generations of the family of the first Lord Thomson of Fleet. Under the Kenneth R. Thomson estate arrangements, the directors and officers of Woodbridge are responsible for its business and operations. In certain limited circumstances, including very substantial dispositions of Common Shares by Woodbridge, the estate arrangements provide for approval of the Trust Company, as trustee, to be obtained. As of April 9, 2026, Thomson Investments Limited is the beneficial owner of 312,518,088 Common Shares, representing approximately 70.56% of the outstanding Common Shares. Of those Common Shares, Woodbridge is the beneficial owner of 300,790,959 Common Shares, representing approximately 67.91% of the outstanding Common Shares. This Amendment No. 24 to Schedule 13D is being filed to report certain information under Item 2, Item 4, Item 5, Item 6, Item 7 and Schedule A (attached as Exhibit 3) hereto. This Schedule 13D amends, restates and updates the amendment to Schedule 13D filed by Woodbridge on November 10, 2025. There has been no material change in the Thomson family's beneficial ownership of Common Shares since then. | ||
