• Ryan Fukushima, CEO and Head of Data at Tempus AI (TEM), reported selling a total of 30,846 shares in open-market transactions on September 1, 2026, for aggregate proceeds of approximately $1,934,244. The sales were in four tranches: 13,046 shares @ $62.12 = $810,418; 10,900 shares @ $62.64 = $682,776; 5,900 shares @ $63.80 = $376,420; and 1,000 shares @ $64.63 = $64,630. These were disposals (sales), which are often routine rather than a buy signal.

Key Details

• Transaction date: September 1, 2026. Form 4 filed September 3, 2026 (timely within typical two-business-day requirement).
• Total shares sold: 30,846; total proceeds: ~$1.93M.
• Per-tranche notes: reported prices are weighted averages; underlying per-share prices ranged as follows: 61.33–62.32; 62.33–63.32; 63.33–64.31; and 64.34–65.00 (the filing offers to provide full breakdowns on request).
• Notable footnote: one tranche (and/or the trades) was executed pursuant to a Rule 10b5-1 trading plan adopted by the reporting person’s spouse on March 12, 2026.
• Shares owned after the transaction: not provided in the excerpted filing.

Context

• Sales by executives can be routine (diversification, tax planning, pre-set plans). Because at least some of these sales were executed under a 10b5-1 plan established by the spouse, they may have been pre-arranged. This filing reports disposals, not purchases—purchases typically carry stronger signals about insider sentiment.
