AI Insider Summary

Michael Brophy's Natera record carries an obvious data artifact — two option-exercise (M) lines dated 2029 — but underneath it the genuine 2026 activity is straightforward: a series of NTRA open-market sales in late April and early May 2026 (482 shares at $210.49, 313 at $206.16, 200 at $197.26) totaling part of a 927K-share cumulative disposition. The future-dated rows should be ignored, not summarized.

Strip them out and the real picture is clean. The valid recent tape is a run of NTRA open-market sales in spring 2026 — 482 shares at $210.49 on May 4, 313 at $206.16 on May 1, 200 at $197.26 on April 29 — small lots clearing in the high-$190s to low-$210s. Over the full history the record shows about 927,000 shares sold with no recorded buys, so Brophy reads as a steady, modest seller of his Natera stake.

The takeaway for NTRA watchers is twofold: first, the 2029 rows are noise and any tool surfacing them is mis-dating a derivative event; second, the underlying behavior is unremarkable scheduled selling into a $200-ish stock, consistent with diversification rather than a signal about the company.
