AI Insider Summary

Jonathan Sheena's Form 4 record at Natera, Inc. is entirely on the selling side: 789 transactions since 2015, with 2,070,093 shares sold and zero bought. His recent activity follows a systematic, multi-tranche selling pattern — small sales spread across a range of prices on each trading date rather than one lump transaction. May 13, 2026 saw six tranches (9 to 360 shares each) at prices between $199.43 and $203.30. By June 15, sales of 300 to 1,750 shares landed between $210.29 and $213.54. June 17 brought nine separate tranches ranging from 15 to 301 shares, priced between $218.14 and $222.14. And July 13, 2026 — his most recent recorded transactions — saw six tranches of 400 to 800 shares each, priced between $262.72 and $268.39. Taken together, the sale prices embedded in this routine, scheduled selling program show Natera's stock climbing roughly 33% between mid-May and mid-July 2026.

A granular, multi-tranche selling pattern

Rather than selling a single block on any given date, Sheena's recent transactions are consistently split into several smaller tranches priced individually — the hallmark of an algorithmic or broker-executed sale spread across a trading session. May 13, 2026 shows six separate sales (9, 285, 360, 96, 30, and 290 shares) at prices from $199.43 to $203.30. June 15, 2026 brings four tranches (300, 500, 600, and 1,750 shares) between $210.29 and $213.54. June 17, 2026 is the most fragmented: nine separate sales ranging from 15 to 301 shares, priced between $218.14 and $222.14.
