Chapman Steven Leonard, CEO and President of Natera (NTRA), has filed 78 Form 4 transactions, all of them sales. The total value of those sales is roughly $97 million. There are no open-market purchases, no acquisitions, and no exercises of options in the record. Every transaction is coded S, meaning an open-market sale. The selling is concentrated and recent. Leonard filed 25 sales between April 27 and August 3, 2026. The largest single day was June 4, when he reported 13 separate sales totaling about $8.9 million. Individual transactions that day ranged from $176,732 to $1.52 million. He also sold $909,572 on July 28, $570,474 on July 27, and $728,854 on April 27. The most recent cluster, on August 3, includes seven sales worth a combined $817,430. The pattern is one-directional. Leonard has not bought a share of NTRA in any filing covered by this data, and his recent activity is entirely on the sell side. The dollar values are large, but the transactions are routine open-market sales by a CEO with a concentrated position. There is no indication of gifts, tax withholdings, or option exercises, which often appear in insider filings. The record is simply a steady stream of sales across five months.
