A story on the same day is not a cause, and a group move is not proof either. Group: the median of IDXX, LNTH, CLDX and NTLA that day, the largest companies in NEOG’s SEC industry; “moved with NEOG” means the same direction and at least half the size.

What’s next · results

Before the next report: what the first day after the last four did

Six trading days after each results filing (SEC 8-K, Item 2.02). NEOG reports before the open, so day 1 is that day’s close. Each time, day 6 ended on the same side as day 1.

Same industry

NEOG against four same-industry peers, a year at 100

NEOG is up 2.2 times in a year. All four did less: Lantheus Holdings (+87.1%), Celldex Therapeutics (+21.7%), Idexx Laboratories (−14.5%) and Intellia Therapeutics (−48.0%). Weekly closes, Oct 10, 2025 = 100, on a log scale so a 2.2-fold rise and a 48.0% fall both read honestly.

End-of-day closes (Databento EOD), the last close of each week. The four peers are the largest US-listed companies by market value in NEOG’s SEC industry (In Vitro & In Vivo Diagnostic Substances) with a year of closes. It shows what the closes did; a move here is not a cause, a forecast or a call.
