Rabinowitz Matthew, serving as executive chairman of Natera, Inc. (NTRA), has been a consistent seller of company stock over the past year, with SEC Form 4 filings showing 70 total transactions—all sales—totaling roughly $82.1 million. The most recent activity, clustered in June and July 2026, shows a heavy concentration of open-market sales (code "S") across multiple dates. On June 12, 2026, he executed a series of sales totaling approximately $8.2 million, with individual transactions ranging from $352,069 to $2.58 million. A larger batch followed on June 15, 2026, with 11 separate sales aggregating roughly $11.1 million, including a single transaction worth $2.56 million. The pattern continued into July, with sales of $280,000 on July 6 and $447,523 on July 27, 2026. Notably, Rabinowitz has recorded zero open-market purchases (code "P") and no acquisitions (code "A") during this period, aside from a single zero-value grant on May 5, 2026, which is compensation rather than a conviction buy. The absence of any buying activity—even token—alongside a steady stream of sales suggests a clear selling bias. The transactions are exclusively in NTRA, and the dollar values are substantial, with the largest single sale hitting $2.57 million. While the filings do not indicate the reason for the sales, the volume and frequency—particularly the concentrated June activity—point to a deliberate, ongoing liquidation of a significant stake in the company.
