Why is Olin Corp. (OLN) stock moving?

OLN rallied from about $15.5 on Oct 22 to a $18.15 close on Nov 2, peaking at $18.555 intraday on Nov 5, after Q3 results on Oct 29. Q3 EPS of $0.13 beat the $0.12 estimate, but sales of $1.748B missed the $1.834B estimate, and adjusted EBITDA and net income fell year over year even though sales rose. The stock jumped 9.6% to $17.60 on Oct 30 on 6.67M shares, the largest volume in the window. Several brokers then raised targets (RBC and Citigroup to $19, Truist and Wells Fargo to $17, Deutsche Bank to $19 with Hold), and the stock has since eased to $17.50 on Nov 10. Volume has dropped to about 2.0-2.2M shares over the last two sessions versus 4-6M earlier, which suggests fading momentum. Structural news is mixed: the EPA finalized PVC emission standards that Olin says give regulatory certainty, and Huntsman plans to close the Olin merger in early 2027 with a $300M synergy target. The Nov 4 amendment extends the receivables facility to July 31, 2028, and the Oct 27 credit agreement amendment depends on the merger closing. Current prices sit near the middle of recent targets, so the upside case rests on the merger and synergy delivery, which are still ahead.

News behind the analysis

About Olin Corp.

Materials · Commodity Chemicals (chlor-alkali, vinyls, epoxy) and Ammunition

Olin is a US-based maker of chlorine, caustic soda, vinyls and epoxy resins, and it also owns Winchester, one of the largest US ammunition makers. It is unusual in pairing a cyclical commodity-chemicals business with an ammunition arm, and it has agreed to an all-stock merger of equals with Huntsman (HUN), with the combined company to be called OlinHuntsman and the deal expected to close in Q1 2027.

How it makes money

Total revenue is roughly $6.7 billion a year (approximate, trailing). Most of it comes from chemicals. Chlor-alkali products and vinyls (chlorine, caustic soda, bleach, hydrochloric acid, vinyl chloride feedstocks) are usually the largest segment, followed by epoxy resins. Winchester brings in roughly a quarter to a third of revenue by selling sporting and law-enforcement ammunition, plus military ammunition, including running the US Army's Lake City plant under contract. Olin pays a quarterly dividend of about $0.20 per share.
