Gary M. Pfeiffer, a director at Quest Diagnostics, has reported the sale of 1,203 shares of the company's stock. This transaction, executed on October 26, 2026, is part of a Rule 10b5-1 sales plan, which allows insiders to sell shares at predetermined times to avoid accusations of insider trading. The sale reflects Pfeiffer's ongoing financial management, as he continues to hold 29,802 shares following the transaction.

Quest Diagnostics, incorporated in Delaware, operates within the medical laboratories sector, providing diagnostic testing services. The company is headquartered in Secaucus, New Jersey, and is recognized under the ticker symbol DGX. The recent filing, dated October 28, 2026, is categorized as a Form 4, which reports changes in ownership by insiders.

According to the filing, the sale was executed at a price of $243 per share. This indicates a calculated move by Pfeiffer, who has been actively managing his holdings in the company. The filing states, "This sale reported was effected pursuant to a Rule 10b5-1 sales plan adopted by the reporting person."
