Fesko John 4

What Happened

• John Fesko, President and Chief Business Officer of Natera (NTRA), received 1,774 restricted stock units (RSUs) on 2026-03-09 that were fully vested at issuance. Each RSU represents a right to one share.
• To satisfy tax withholding obligations tied to that vesting, Fesko sold 707 shares in an open market transaction on 2026-03-10 at $204.13 per share, generating proceeds of $144,322. This sale appears to be a routine disposition to cover taxes rather than a market-timing purchase.

Key Details

• Grant/Acquisition: 1,774 RSUs issued/vested on 2026-03-09 (no purchase price; RSUs convert to one share each) (Footnotes F1, F2).

• Purpose/Plan: The sale was effected to satisfy tax withholding and was made pursuant to a written instruction intended to satisfy the affirmative-defense conditions of Rule 10b5-1(c) under the Exchange Act (per the filer’s Stock Unit Agreement).

Context

• RSU vesting and subsequent sell-to-cover for taxes is a common, routine insider action and does not necessarily indicate a change in the insider’s view of the company.
• The sale being tied to tax withholding and executed under a written instruction/10b5-1 framework further indicates it was a prearranged, administrative disposition rather than an opportunistic trade.
