Smart Money Convergence

REGN does not currently show a 13F-and-insider convergence signal — its insider confidence score is 0/100, below the threshold this product uses to flag combined buying pressure.

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.

This 8-K is largely a procedural filing: it attaches that press release as Exhibit 99.1 and 'furnishes' it to the SEC. The excerpt doesn't contain the actual revenue or profit numbers—those would be in the attached release.
