Executive Summary

On November 2, 2026, John Fesko, an Officer of Natera, Inc., filed a Form 144 notice of proposed sale covering 291 shares of common stock with an aggregate market value of approximately $120,561.30. The securities are slated to be sold through ETrade Corporation around November 2, 2026.

Transaction & Holding Context

• Nature of Acquisition: The 291 shares being liquidated derive from an RSU grant of 11,832 shares that vested on October 31, 2026, as compensation for services rendered.
• Transaction Size: The proposed disposition of 291 shares represents a negligible fraction of the company's 144,144,170 outstanding shares.
• Recent Prior Sales: Over the preceding three months, Fesko sold:
  • 898 shares on October 28, 2026 ($382,853.32)
  • 781 shares on October 27, 2026 ($317,086.11)
  • 6,517 shares on August 10, 2026 ($2,095,411.01)
  • 295 shares on August 3, 2026 ($79,056.86)

Significance

The planned sale is rated as Low trading significance given the minimal share count and dollar value relative to both Natera's market capitalization and the officer's prior quarterly transaction volume. The timing aligns with typical tax-withholding or routine post-vesting equity management following the October 31 RSU vesting date.
