Delaet Ingrid, Chief Regulatory Officer at Neurocrine Biosciences (NBIX), has filed 63 Form 4 transactions, all in a single company, with a pronounced sell-side bias. Across the entire filing history, her open-market sales total roughly $6.69 million, while she has recorded zero open-market purchases. The most recent activity, spanning July 7–10, 2026, shows a cluster of seven sales and matching option exercises, with sale values ranging from $488,672 to $1,507,135 per transaction. Combined, those four sales alone brought in approximately $3.39 million, each paired with an option exercise (code M) of a lower dollar amount, a pattern consistent with exercising options and immediately selling the shares.
The transaction structure is largely mechanical. The July 2026 sales are each accompanied by an option exercise on the same date, and earlier filings show routine grants (code A) and shares withheld for taxes (code F), such as the February 13, 2026, filings where $1.33 million in shares were withheld to cover tax obligations. A smaller sale of $61,695 occurred on July 10, 2025, and another of $88,125 on February 13, 2025, both also paired with option exercises. There is no evidence of open-market buying at any point in the record, and the only non-sale, non-exercise transactions are compensation-related grants and automatic tax withholdings.
The data reveals a consistent, recurring pattern of option exercises followed by same-day sales, concentrated in the weeks after quarterly vesting or grant dates. The most recent cluster in early July 2026 is the largest by dollar volume, with total sales of roughly $3.39 million over four days. While the absence of purchases and the steady cadence of sales could be interpreted as a bearish signal, the mechanical pairing with option exercises and tax withholdings suggests these are routine liquidity events tied to equity compensation rather than discretionary market timing. No purchases have been recorded at any point, leaving the overall bias firmly on the sell side.
