Fesko John, President and Chief Business Officer, has demonstrated a consistent pattern of selling shares in Natera Inc. (NTRA) over the past two years, with no recorded purchases in SEC filings. His 27 reported transactions since early 2024 have all been sales, totaling approximately $7 million in aggregate value. The most significant single transaction occurred on January 20, 2026, when he sold shares worth $4.18 million—by far the largest disposal in the series. Other notable sales include $558,203 and $272,075 on February 3, 2026, and $239,072 on July 28, 2025. Smaller but repeated disposals, such as $144,322 on March 10, 2026, and $188,577 on January 27, 2026, suggest an ongoing divestment strategy rather than isolated liquidity events. The transactions are interspersed with occasional "A" coded filings indicating awards or acquisitions at zero cost, likely representing equity compensation. However, these non-purchase events do not offset the clear selling trend. Fesko’s activity is concentrated solely in NTRA, with no diversification across other securities. The frequency of sales—18 in the most recent period—points to a deliberate reduction in his position, though the filings do not disclose whether the disposals were prearranged or discretionary. The absence of any buy transactions over this extended period reinforces a one-directional pattern of decreasing his stake in the company.
