Richard Chen, the President and Chief Medical Officer of Personalis, Inc. (NASDAQ: PSNL), executed a significant divestment of company equity on July 15, 2026. The transaction involved the sale of 100,000 shares, generating proceeds of $1,515,000. This activity was facilitated by a Rule 10b5-1 trading plan adopted in late December 2025, allowing for the automated execution of sales regardless of market conditions or insider status.
The sale followed the exercise of stock options previously granted to Chen, which were fully vested and carried an expiration date of May 24, 2027. The exercise of these options required a capital outlay of $244,000, calculated at a strike price of $2.44 per share. Following this transaction, Chen's direct ownership in Personalis stands at 173,880 shares.
The timing of this sale occurs as the stock trades near its 52-week high of $16.15, reflecting a substantial 146% return over the preceding year. Market analysis suggests the stock may be trading at a premium relative to its calculated fair value. The shares were sold at prices ranging from $15.01 to $15.45, with a weighted average price of $15.15 per share.
In other recent developments, Personalis has secured critical regulatory approvals that expand its operational footprint. The company received UKCA marking for its NeXT Personal Dx test, permitting clinical use across England, Wales, and Scotland. This regulatory clearance enables pharmaceutical companies to utilize the test in multinational clinical trials spanning both U.S. and UK sites.
Additionally, Personalis obtained Class A CE-IVD marking for its EDTA Blood Collection Kit and cfDNA Blood Collection Kit under the European Union’s In Vitro Diagnostic Regulation. This approval facilitates the use of these collection tools in clinical trials within the European Union and Great Britain. These regulatory milestones are significant for the healthcare and diagnostics sectors, as they remove barriers to entry in key international markets.
On the coverage front, Personalis gained expanded Medicare coverage for its NeXT Personal minimal residual disease test. The coverage now includes monitoring treatment response to neoadjuvant therapy in patients with Stage II-III Triple-Negative Breast Cancer or HER2-positive breast cancer. Moreover, Medicare coverage has been extended to include immunotherapy monitoring for patients with late-stage solid tumors, following a study with the Vall d’Hebron Institute of Oncology.
At its recent annual meeting, Personalis shareholders elected directors and approved various proposals, with 87.76% of the company’s outstanding shares represented. This level of shareholder participation indicates active governance engagement.
