Olin Corporation (OLN) Earnings: Q3 2026 Results and Next Report Date

The quarter ended September 30, 2026 and Olin published the results on October 29, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison.

• On June 15, 2026, Olin agreed to an all-stock merger of equals with Huntsman to form OlinHuntsman Corporation. Huntsman holders would receive 0.5476 Olin shares per share, and Olin expects the deal to close in the first quarter of 2027. Q3 2026 results include $13.7 million of acquisition-related costs for it.
• The Blue Water Alliance joint venture, whose trading volumes were part of Chlor Alkali Products and Vinyls sales, ended operations at the end of 2025.

How Olin splits revenue in its own release, under its own labels, for Q3 2026 against Q3 2025. Indented lines are parts of the line above them.

• Olin's Chlor Alkali Products and Vinyls revenue was $851 million in Q3 2026, down 8% from $924 million in Q3 2025, 49% of total revenue.
• Olin's Epoxy revenue was $412 million in Q3 2026, up 18% from $350 million in Q3 2025, 24% of total revenue.
• Olin's Winchester revenue was $485 million in Q3 2026, up 10% from $440 million in Q3 2025, 28% of total revenue.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

From the earnings release

Olin's next report is expected around January 28, 2027, a date estimated from its reporting history that the company has not yet confirmed. This page will show Q3 2026 until those results are out and have been checked against the release.

Each quarter keeps its own page with the figures as reported, so a link to one stays pointed at the same numbers after the next report.

• Q3 2026 (this page), reported Oct 29, 2026

Olin reports three segments. In Q3 2026, Chlor Alkali Products and Vinyls had sales of $850.8 million, Winchester ammunition $484.7 million and Epoxy $412.2 million, for total sales of $1,747.7 million, up $34.5 million, or 2%, from $1,713.2 million. (Olin Q3 2026 release, Oct 29, 2026; Olin Form 10-Q, Q3 2026, Oct 30, 2026)

Chlor Alkali Products and Vinyls sales fell from $924.0 million because of lower volumes, mainly lower trading volumes from the Blue Water Alliance joint venture, which ended at the end of 2025, and lower VCM volumes, partly offset by higher pricing. Caustic soda sales were $363.2 million, against $410.2 million, and chlorine, chlorine derivatives and other products $487.6 million, against $513.8 million. Olin said operating issues at its Freeport, Texas VCM plant cost $32.1 million in higher costs and lost sales. (Olin Q3 2026 release, Oct 29, 2026; Olin Form 10-Q, Q3 2026, Oct 30, 2026)

Epoxy sales rose to $412.2 million from $349.6 million on higher volumes and pricing. Aromatics and allylics brought in $169.8 million and epoxy resins and formulated solutions $242.4 million. (Olin Q3 2026 release, Oct 29, 2026; Olin Form 10-Q, Q3 2026, Oct 30, 2026)

Winchester sales rose to $484.7 million from $439.6 million. Commercial ammunition sales were $206.6 million, against $168.9 million, and military and law enforcement $278.1 million, against $270.7 million. Winchester runs the Lake City Army Ammunition Plant in Independence, Missouri, making 5.56mm, 7.62mm and .50 caliber military rounds under a U.S. Army contract. (Olin Form 10-Q, Q3 2026, Oct 30, 2026; Olin Form 10-K, 2025, Feb 20, 2026)

Olin's sales are mostly domestic. United States customers accounted for $1,223.3 million of Q3 2026 sales, or about 70%, with $142.1 million from Europe and $382.3 million from other foreign markets. (Olin Form 10-Q, Q3 2026, Oct 30, 2026)

Olin reports GAAP EPS only, with no adjusted EPS. Q3 2026 diluted EPS was $0.13, against $0.37 a year earlier, on net income of $14.4 million, against $42.8 million. The quarter carried $13.7 million of acquisition-related costs for the Huntsman merger and $1.7 million of restructuring charges. (Olin Q3 2026 release, Oct 29, 2026)

Chlor Alkali Products and Vinyls earnings included a $5.0 million pretax benefit, against $32.0 million a year earlier, mainly from the Section 45V clean hydrogen production tax credit. Olin's effective tax rate was 15.8% on income before taxes of $17.1 million, against a negative rate of 5.3% in Q3 2025. (Olin Q3 2026 release, Oct 29, 2026; Olin Form 10-Q, Q3 2026, Oct 30, 2026)

Average diluted shares were 115.0 million, against 115.1 million. Olin repurchased no stock in the first nine months of 2026, against $40.4 million a year earlier, and paid a $0.20 quarterly dividend. (Olin Q3 2026 release, Oct 29, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

Olin gives a one-quarter adjusted EBITDA range in its release and no sales or EPS outlook. For Q4 2026 it expects adjusted EBITDA of $80 million to $100 million, against $191.4 million in Q3 2026, citing normal seasonality, year-end customer destocking in Chemicals, higher feedstock costs, subsidized Asian exports and planned maintenance turnarounds. (Olin Q3 2026 release, Oct 29, 2026)

In its 10-Q Olin said it expects about $35 million to $40 million of acquisition-related costs for the Huntsman merger in 2026 and environmental expenses of $25 million to $30 million. (Olin Form 10-Q, Q3 2026, Oct 30, 2026)

A consensus figure is the average of the models published by the analysts who cover Olin, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones Olin's own release and filings put weight on for Q3 2026, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning OLN is on is OLN a buy or a sell?, what analysts expect next is on the OLN forecast, and what the company does is on the Olin Corporation (OLN) stock page.

Every number on this page can be traced to a document Olin published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
