According to the latest Form 4 filing, Eric P Lefkofsky, CEO, Chairman, Director and over 10% shareholder of Tempus AI, Inc. (ticker: TEM), executed multiple planned sales of Class A Common Stock on July 28, 2026 under a Rule 10b5‑1 trading plan adopted on March 8, 2026. Through various entities he controls or for which he serves as trustee (including Gray Media, LLC, Blue Media, LLC, Lefkofsky Family Foundation, Vas.org Foundation and others), he sold an aggregate of approximately 249,000 shares in numerous transactions at weighted average prices ranging from about $40.79 to $43.13 per share. Following these sales, he continues to beneficially own several million shares through different LLCs, foundations and GRATS. While the trades are pre‑planned and may reflect portfolio and liquidity management, sizable insider sales by a key executive and major shareholder can be viewed as a potentially bearish signal for market sentiment, and investors should monitor future filings and ownership changes.
