Olin Corporation (OLN) Stock Price & How to Invest

Olin Corporation, incorporated in Virginia in 1892 and headquartered in Clayton, Missouri, is a vertically integrated global manufacturer and distributor of chemical products and the leading U.S. manufacturer of ammunition. Its largest business, Chlor Alkali Products and Vinyls, produces chlorine, caustic soda, ethylene dichloride (EDC), vinyl chloride monomer, chlorinated organics, hydrochloric acid, hydrogen, and bleach, and represented about 54% of 2025 sales. Olin is one of the world's largest chlor alkali producers, with roughly a fifth of North American capacity. The Epoxy segment (about 20% of 2025 sales) makes epoxy resins and precursors such as allyl chloride, epichlorohydrin, and phenol and acetone aromatics. The Winchester segment (about 26% of sales) produces sporting, law-enforcement, and small-caliber military ammunition, reloading components, and clay targets, and in April 2025 completed the acquisition of the small caliber ammunition assets of AMMO, Inc., adding a 185,000 square foot plant in Manitowoc, Wisconsin.

Olin's economics are commodity-driven and highly sensitive to the electrochemical unit (ECU) value of chlorine and caustic soda, epoxy resin spreads, raw material and energy costs, and ammunition demand. Because chlorine and caustic soda are co-produced in fixed ratios, the mix of demand between them heavily influences profitability. On June 15, 2026, Olin and Huntsman Corporation announced an all-stock merger of equals under which Huntsman holders would receive 0.5476 Olin shares each; special shareholder meetings were set for August 25, 2026 with a July 9, 2026 record date, and the companies targeted a first-half 2027 close and a combined workforce of roughly 14,000. Until the deal closes or terminates, it is the dominant driver of how the stock behaves.

Olin's earnings are highly cyclical and commodity-priced, so weak chlorine, caustic soda, EDC, and epoxy pricing can push results to a loss quickly, as the first quarter 2026 net loss of about $83 million showed. The company carries meaningful debt and high operating leverage, which amplifies both downturns and recoveries. The announced Huntsman merger introduces deal-completion risk, including shareholder approval, regulatory review, and integration execution, and a fixed exchange ratio means the value received moves with the two share prices. Legacy environmental and legal liabilities, including litigation charges tied to a VCM customer dispute, and exposure to energy, ethylene, and metals input costs add further uncertainty. Ammunition demand and the timing of military contracts can also swing the Winchester segment.

A simple financial snapshot. These are approximations and refresh quarterly; for current figures see Olin Corporation's investor relations page or your broker.

• Revenue (Full Year 2025): ~$6.7 billion
• Revenue (Q1 2026): ~$1.58 billion (down ~4% year over year)
• Net Income (Q1 2026): ~-$83 million (loss), ~-$0.73 per diluted share
• Adjusted EBITDA (Q1 2026): ~$86 million (down from ~$186 million a year earlier)
• Market Capitalization: ~$2.3 billion
• Trailing P/E / Dividend: Negative on trailing loss; dividend ~$0.80 per share annually (~4% yield)

Olin's trailing price-to-earnings ratio is negative because the trailing twelve months include losses, so investors lean on normalized mid-cycle earnings, EV/EBITDA, and the pending Huntsman exchange ratio instead of reported P/E. The share price near the low $20s and a market capitalization around $2.3 billion reflect a cyclical trough in chlor alkali and epoxy pricing plus deal uncertainty. These figures are approximate and move with commodity prices and merger developments.

There are three common ways to get OLN exposure. Buy shares (or fractional shares) directly at any major broker. Hold an ETF that includes it, which spreads the position across many companies. Or build it into a focused thematic basket, so OLN sits alongside other stocks that express the same thesis.

Walnut takes the basket route. Describe a thesis where OLN fits (for example “AI infrastructure” or “dividend-growth large-caps”) and the AI proposes 5 to 6 constituents with target weights. You review the plan and fund it through your own broker when you're ready.

Olin is a commodity-chemicals and ammunition producer at a cyclical low, with 2026 first quarter results swinging to a net loss as caustic soda, EDC, and epoxy pricing stayed soft. The story is now dominated by the announced merger of equals with Huntsman (fixed exchange ratio of 0.5476 Olin shares per Huntsman share, targeted to close in the first half of 2027), so the shares increasingly trade on deal spread, chlorine and caustic soda price recovery, and Winchester ammunition demand rather than standalone fundamentals. Trailing earnings are negative because of the recent loss, the market capitalization sits near $2.3 billion, and the dividend has held at $0.20 per quarter. The considerations are commodity-price timing, deal-completion risk, and heavy operating and financial leverage.

Whether OLN is worth buying today depends more on your time horizon and what you already hold than on any single call. We walk through valuation, what would have to go right, and the risks in is OLN a buy?, and where the stock could go from here in the OLN stock forecast.
