24.3 billion USD stock-swap merger! Two North American chemical giants merge—hidden industry pain point: the intractable dilemma of chlor-alkali co-production. Can it truly be resolved?

On June 16, Olin Corporation—the largest chlor-alkali producer in the United States—announced a full-stock, share-for-share merger with Huntsman Corporation. The exchange ratio is 0.5476 shares of Olin stock for each share of Huntsman stock, valuing the transaction at approximately USD 2.43 billion. Upon completion, Olin shareholders will hold 54.5% of the combined entity, while Huntsman shareholders will hold 45.5%. The merged company will become a North American chemical powerhouse, with combined 2025 revenues estimated at roughly USD 12.5 billion. Superficially, this appears to be a typical scale-driven consolidation within the chemical industry. Yet, anyone familiar with the fundamental constraints of the chlor-alkali industry will recognize an almost inevitable industrial logic behind this deal—the answer lies in a production ratio known as the ECU (Electrochemical Unit). The捆绑困境 of the chlor-alkali industry To understand this merger, one must first grasp a core constraint of chlor-alkali manufacturing: the ECU ratio (Electrochemical Unit). In chlor-alkali electrolysis, producing 1 ton of chlorine gas (Cl₂) simultaneously yields approximately 1.1 tons of caustic soda (NaOH) and 0.03 tons of hydrogen gas (H₂). These three products are inherently co-produced—you cannot independently adjust output of any single product, nor can you halt chlorine production while continuing to produce caustic soda. This constraint creates immense commercial pressure in practice. Caustic soda demand originates from relatively stable sectors such as papermaking, textiles, and aluminum smelting; chlorine demand, however, concentrates heavily in volatile downstream markets—including polyvinyl chloride (PVC) and phosgene-based chemicals (e.g., MDI, TDI). When chlorine markets soften, chlor-alkali producers face a painful dilemma: either cut production (reducing caustic soda output too, resulting in dual losses), or slash chlorine prices. Yet chlorine is a hazardous gas with limited transport radius and cannot be stored long-term in bulk—it must be consumed locally. Olin Corporation epitomizes a firm long-struggling under this constraint. A globally recognized vertically integrated chemical manufacturer and distributor—and also a leading U.S. ammunition producer—Olin’s core chemical products include chlorine, caustic soda, vinyl products, epoxy resins, chlorinated organics, bleach, hydrogen, and hydrochloric acid. Its Winchester brand manufactures and sells sporting ammunition, law enforcement ammunition, heavy-duty components, small-caliber military rounds and accessories, industrial ammunition, and clay targets. As America’s largest chlor-alkali producer, Olin sources 76% of its electricity from natural gas and hydropower—keeping power costs relatively manageable. Yet persistent difficulty finding outlets for its chlorine has consistently weighed on profitability. Intensifying global competition among chlorine derivatives has forced Olin, at times, to offload chlorine at steep discounts in the spot market. Screenshot from Olin’s official website Huntsman’s true identity: The largest chlorine consumer Within the chemical industry, Huntsman is commonly positioned as a polyurethane and epoxy resin company. It operates three major business units: Polyurethanes, Advanced Materials, and Functional Products. Yet viewed through the lens of chlor-alkali chemistry, Huntsman holds another, more critical identity: one of the world’s primary consumers of chlorine.

Daily Financial Knowledge: Relative Stock Valuation—An investment technique every ordinary investor must master.

Many retail investors fall into a common trap when trading stocks: they focus solely on price movements, chase rumors and hot topics, and never assess whether a stock is 'expensive' or 'cheap.' This is the core reason most individual investors lose money: gambling on luck instead of making decisions grounded in valuation analysis. At its heart, stock investing boils down to just one principle: a good company + a good price. Assessing company quality relies on fundamental analysis; judging whether the price is right hinges on relative valuation. Today, we’ll explain the seven key relative valuation methods in plain, universally accessible language—using a single, consistent real-life analogy throughout. After reading this, you’ll move beyond 'blind stock trading' and truly learn how to use data to determine whether a stock is overvalued, fairly valued, or undervalued. I. First, understand: What is relative stock valuation? Many beginners overcomplicate valuation. In reality, the core logic of relative valuation can be summed up in four words: 'Compare like with like.' You don’t need complex formulas to calculate a company’s precise intrinsic value. Instead, simply apply a standardized 'comparative yardstick'—comparing peers within the same industry or comparing against the company’s own historical valuations—to determine whether the stock is currently overvalued, fairly valued, or undervalued. In simple terms: • Absolute valuation asks: 'What is the company truly worth?' • Relative valuation asks: 'Is it expensive to buy now?' Relative valuation is the most practical, frequently used, and simplest investment technique for ordinary investors—without exception. II. Unified real-life analogy (used throughout) To ensure clarity for all readers, we’ll avoid obscure financial jargon and instead use a relatable, concrete scenario: selling a bubble tea shop—mapping directly onto all corporate financial concepts. Assume: A profitable, stable bubble tea shop • Book value (net assets): RMB 1 million (equipment, interior decoration, deposits, cash—after settling all debts) • Annual revenue (total sales): RMB 2 million • Annual net profit (pure earnings): RMB 200,000 (includes RMB 20,000 in accounts receivable not yet collected) • Annual operating cash flow (actual cash received): RMB 180,000 (some sales are on credit, so not all revenue has been converted to cash) • Shop liabilities: RMB 500,000 loan • Cash reserves: RMB 200,000 • EBITDA (core operating profit: after rent, raw materials, wages, utilities—but before interest, taxes, and depreciation): RMB 400,000 • EBIT (profit after depreciation: subtracting RMB 100,000 for equipment wear and decor aging): RMB 300,000 • Equity sale price (equivalent to market capitalization): RMB 2 million Summary: · Revenue: RMB 2 million · Daily operating costs (raw materials, rent, salaries, etc.): RMB 1.6 million · Depreciation (annual wear-and-tear on equipment and decor): RMB 100,000 · Loan interest: RMB 50,000 · Corporate income tax: RMB 50,000 · Accounts receivable (sales booked but cash not yet collected): RMB 20,000 (included in profit, but no cash inflow yet) · Net profit retained: RMB 180,000 All valuation metrics below will be explained using this bubble tea shop example—ensuring even absolute beginners grasp them instantly. III. Seven Core Relative Valuation Methods (plain-language explanations + examples + applicable scenarios) 1. PE Ratio (Price-to-Earnings)—Measures payback period Core logic: At the company’s current earnings pace, how many years would it take to recoup your investment? Formula: Market Capitalization ÷ Annual Net Profit Bubble tea shop example: RMB 2 million (sale price) ÷ RMB 200,000 (annual net profit) = 10x PE Plain-language interpretation: This bubble tea shop reliably earns RMB 200,000 per year—no growth, no losses, and all profits distributed to you. You’d recover your entire investment in 10 years.
