Impact Evaluation

• Market Cap Context: The $11.5M sale is minor relative to Tempus AI's $12.18 billion market capitalization. The transaction value constitutes less than 0.1% of the company's total market value, indicating a low financial impact.
• Ownership Concentration: While the insider is a major stockholder, this specific sale represents a very small portion (under 0.1%) of the 172.86 million shares outstanding, having no material effect on ownership concentration.
• Transaction Significance: Based on quantitative metrics, the transaction's significance is low. Both the value as a percentage of market cap and the shares as a percentage of outstanding float fall below the 0.1% threshold for low significance.

Market Impact Analysis

Stock Impact Prediction

• Direction: Neutral
• Reasoning: The sale is being conducted under a 10b5-1 trading plan adopted on March 4, 2025. Such plans are established in advance to allow insiders to sell shares over time without being accused of trading on non-public information. This removes much of the negative sentiment typically associated with insider selling.

Volume & Sentiment

• Expected Volume Impact: Minimal. The number of shares is unlikely to cause significant price pressure or unusual volume spikes given the company's size.
• Sentiment Indicator: Neutral. The market generally views sales under 10b5-1 plans as routine liquidity events for insiders rather than a bearish signal on the company's future prospects.

Additional Context

Transaction Notes

• Special Circumstances: The filing explicitly notes the sale is pursuant to a 10b5-1 trading plan. The remarks also clarify the sale is being made by two LLCs, Blue Media, LLC and Gray Media, LLC, for which Mr. Lefkofsky is the sole manager. This is an indirect sale.
• Recent History: The filing discloses several multi-million dollar sales by these same entities in the preceding three months, establishing a clear pattern of planned dispositions.
