Smart Money Convergence

NBIX does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.

13F data as of 2026-09-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

2026-07-31 (/A)

This 8-K from Neurocrine Biosciences (NBIX) is mostly a procedural financial-disclosure filing tied to its pending acquisition of Soleno Therapeutics. It folds in Soleno's audited financial statements for the year ended Dec. 31, 2025, its unaudited interim statements for the three months ended March 31, 2026, and unaudited pro forma combined income statements for Neurocrine/Soleno covering the six months ended June 30, 2026 and the year ended Dec. 31, 2025. The exhibits also include the merger agreement dated April 5, 2026 and a credit agreement dated May 14, 2026. One quirk: the filing text mentions a pro forma period that ends after the May 14, 2026 report date, which looks like a typo or a bad excerpt, but the filing itself doesn't clarify it.
