Rabinowitz Matthew 4

What Happened

• Matthew Rabinowitz, Executive Chairman and Director of Natera, sold a total of 100,000 NTRA shares in open-market transactions (code S) executed on June 12 and June 15, 2026. The combined proceeds were approximately $21.45 million (about $21,447,308). Individual trades report weighted-average prices; the overall sale prices ranged roughly from $208.88 to $219.98 per share.
• These were sales (liquidations), not purchases or option exercises. The reporting indicates the transactions were effected pursuant to a Rule 10b5-1 trading plan adopted by Rabinowitz on March 13, 2026, which generally means the sales were pre-planned.

Context

• Rule 10b5-1 plans allow insiders to schedule trades in advance and are commonly used to avoid accusations of trading on nonpublic information; sales under such plans are generally viewed as pre-planned rather than immediate signals of the insider’s current view.
• For retail investors: purchases by insiders can be more informative about confidence in future prospects than routine sales; here the filing documents a sizable, planned sale by the company’s Executive Chairman.
