Shareholders of Owens Corning
Owens Corning’s company profile lists one shareholder record on file — Vanguard Group Inc, shown at a 19.1% stake as of 4 September 2026 — though this figure differs from the stakes most recently reported directly by Vanguard’s SEC-registered reporting entities (see below); readers should rely on the primary SEC filings for the current position. Because Owens Corning is a New York Stock Exchange-listed public company, only beneficial owners whose stake exceeds 5% of outstanding common stock must be individually disclosed under SEC Schedule 13G/13D rules; the great majority of Owens Corning’s shareholders, including individual investors and smaller institutional holders, are not named on the public record.
Current SEC Schedule 13G filings identify BlackRock, Inc. as the largest publicly disclosed holder, reporting beneficial ownership of 8,069,391 shares (10.0%) as of 4 June 2026. Vanguard-affiliated entities also hold reportable stakes, disclosed separately following an internal SEC-reporting realignment effective 12 January 2026: Vanguard Portfolio Management LLC reported 5,532,481 shares (6.88%) and Vanguard Capital Management reported 4,243,450 shares (5.27%), both as of 31 March 2026, together representing approximately 12.15% of outstanding shares. All of these positions are disclosed as passive investments, without a stated intent to influence or control the company.
Data availability
Availability for Owens Corning is best described as major shareholders only: SEC disclosure rules require public identification of beneficial owners exceeding the 5% threshold, so only institutional holders crossing that level are individually named, and the complete shareholder register is not publicly available.
