Insights

CEO/Chair and 10% owner sells shares under a 10b5-1 plan while retaining very large indirect holdings.

The filing reports open-market sales of Class A common stock by the CEO, Chairman, and 10% owner of Tempus AI, Inc.. Two transactions on 11/24/2025 disposed of 33,250 and 133,000 shares, both coded "S" for sales, at a weighted average price of about $ 74.1 per share, executed under a Rule 10b5‑1 trading plan adopted on March 4, 2025. These sales reduced positions held indirectly through Gray Media, LLC and Blue Media, LLC.

Despite these sales, the reporting person continues to show very large beneficial ownership across several entities, including multi‑million‑share positions through Gray Media, Blue Media, and other affiliated vehicles, plus additional holdings via a family GRAT and foundation. The Rule 10b5‑1 designation signals that these trades followed a pre‑set plan rather than ad hoc timing. That framework can limit concerns about opportunistic trading, while still reflecting incremental diversification of personal holdings.

Key items to watch are any pattern of continued sales from these entities and any future changes in the reporting person’s role as Director, CEO, Chairman, or 10% owner. Subsequent Form 4 filings will show whether these transactions are isolated or part of a larger, ongoing disposition program over the coming quarters.
