Insights

Equity market & insider-transactions analyst

Routine, pre-planned insider sale of a small share amount.

Director David R. Epstein sold 250 shares of Tempus AI, Inc. Class A Common Stock in an open-market transaction at $49.40 per share. Following the sale, he continues to hold 31,464 shares directly, so the transaction is small relative to his reported position.

The filing states the sale was made under a Rule 10b5-1 trading plan adopted on August 27, 2024. Such plans are established in advance and execute automatically according to preset instructions, which generally reduces the informational value of the precise timing of the trade.

There are no derivative exercises or complex instruments reported in this filing, and the derivative position table is empty. Subsequent company filings may provide additional context on any future transactions or changes in Epstein’s holdings.

Class A Common Stock financial

"executed a small open-market sale of 250 shares of Class A Common Stock"

Class A common stock is a category of a company’s shares that carries a specific set of ownership rights—most commonly defined voting power and claims on dividends—set out in the company’s charter. For investors it matters because the class determines how much influence you have over corporate decisions, the share’s likely dividend and trading behavior, and how it compares in value to other share classes, like choosing a particular seat with different privileges at the company’s decision-making table.

open-market sale financial

"executed a small open-market sale of 250 shares"

An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.

Rule 10b5-1 trading plan regulatory

"The sale was carried out pursuant to a pre-arranged Rule 10b5-1 trading plan"

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.
