While I could not locate a specific 13G/A filing by Eric P. Lefkofsky on May 9, 2025, that explicitly states a 17.55% decrease in his reported ownership, an analysis of recent SEC filings for Tempus AI, Inc., where Mr. Lefkofsky serves as CEO, indicates a notable change in his beneficial ownership around that timeframe.
According to a Definitive Proxy Statement (DEF 14A) filed by Tempus AI, Inc. on April 7, 2025, Eric P. Lefkofsky's beneficial ownership of Class A Common Stock was reported as 39,825,028 shares as of March 18, 2025.1 In an earlier S-1 Registration Statement filed on February 25, 2025, his beneficial ownership of Class A Common Stock was 47,482,532 shares as of February 21, 2025.2
This represents a decrease of 7,657,504 shares of Class A Common Stock between February 21, 2025, and March 18, 2025, which translates to approximately a 16.12% reduction in his Class A Common Stock holdings. This percentage is in close proximity to the 17.55% decrease you mentioned. The discrepancy could be due to varying calculation bases (e.g., including or excluding Class B shares), rounding, or a slightly different reporting period.
Generally, a decrease in reported ownership in SEC filings such as a 13G/A (or other beneficial ownership reports like Form 4, DEF 14A, or S-1) can occur for several reasons:
- Sale of Shares: The most common reason is the direct sale of shares by the individual or entities they control.
- Distribution or Transfer of Shares: Shares might be distributed from an entity controlled by the individual to other entities or individuals, or transferred to trusts or foundations where the individual no longer holds direct beneficial ownership for reporting purposes.
- Dilution from New Issuances: If the company issues new shares (e.g., through an offering or employee stock plans), existing shareholders' ownership percentages can decrease even if they haven't sold any shares.
- Reclassification of Shares: Changes in share classes, voting rights, or the structure of holdings can sometimes impact reported ownership percentages.
It is important to note that 13G/A filings are typically filed by passive investors who own more than 5% of a company's stock.3 For a CEO, changes in ownership are often reported on Form 4 (Statement of Changes in Beneficial Ownership) or disclosed in proxy statements (DEF 14A) or registration statements (S-1), which provide detailed beneficial ownership tables.
