Some Tempus AI, Inc. (NASDAQ:TEM) shareholders may be a little concerned to see that the Independent Director, Theodore Leonsis, recently sold a substantial US$3.1m worth of stock at a price of US$69.90 per share. That sale reduced their total holding by 33% which is hardly insignificant, but far from the worst we’ve seen.
The Last 12 Months Of Insider Transactions At Tempus AI
Over the last year, we can see that the biggest insider sale was by the Co-Founder, Eric Lefkofsky, for US$82m worth of shares, at about US$58.75 per share. That means that an insider was selling shares at slightly below the current price (US$73.78). When an insider sells below the current price, it suggests that they considered that lower price to be fair. That makes us wonder what they think of the (higher) recent valuation. While insider selling is not a positive sign, we can’t be sure if it does mean insiders think the shares are fully valued, so it’s only a weak sign. We note that the biggest single sale was only 4.3% of Eric Lefkofsky’s holding.
