Datadog, United Therapeutics Executives Sell Stock Under Pre-Arranged Plans

Top executives at Datadog and United Therapeutics sold millions of dollars in company stock, according to regulatory filings disclosed on Monday, July 27. The transactions were conducted under pre-arranged trading plans, while other filings revealed a significant purchase at Energizer Holdings by a major shareholder.

Notable Insider Sales

At the cloud monitoring firm Datadog (DDOG), two key insiders sold substantial amounts of stock on July 23. Chief Executive Officer Olivier Pomel sold 47,054 shares for a total of approximately $11.5 million, while Director Amit Agarwal sold 20,000 shares for roughly $4.9 million. Both sets of transactions were executed pursuant to pre-established 10b5-1 trading plans.

These sales come as Datadog's stock has performed strongly, gaining 85% year-to-date, according to the source data. The filings also noted that both executives converted an equivalent number of Class B shares into the Class A shares that were sold.

Similarly, United Therapeutics (UTHR) Chairperson and CEO Martine A. Rothblatt sold 9,500 shares for approximately $5.04 million on July 27. This transaction, which also involved exercising stock options, was conducted under a 10b5-1 plan adopted in November 2025. The sale followed a period of strong performance for the stock, which has returned 77% over the past year.

Other significant sales included:

• Safety Insurance Group (SAFT): 10% owner SRB Corp sold 38,835 shares for a total of $4 million on July 24.

Several other insiders made smaller, open-market purchases, which can be interpreted as a sign of confidence in their companies' prospects.

• Metropolitan Bank Holding Corp. (MCB): CFO Daniel F. Dougherty acquired 1,000 shares for $89,980 on July 23.
• Oak Valley Bancorp (OVLY): Director Gary Strong bought 2,000 shares for $65,000 on July 27.

Context for Investors

Insider transactions are closely monitored by investors for insights into executive sentiment. While purchases are often viewed as a bullish signal, sales do not necessarily indicate a negative outlook. Insiders sell shares for numerous reasons, including portfolio diversification, tax planning, and personal financial management.

The use of 10b5-1 plans, as seen in the Datadog and United Therapeutics sales, allows insiders to schedule transactions in advance. This provides an affirmative defense against potential accusations of trading on material non-public information. Therefore, investors typically view sales under these plans as less indicative of an insider's current view on the company's short-term prospects.
