Olin and Huntsman Announce Transformative \$12+ Billion All-Stock Merger of Equals: Key Details for Investors
Executive Summary
Olin Corporation (NYSE: OLN) and Huntsman Corporation (NYSE: HUN) have entered into a definitive agreement to combine in an all-stock “merger of equals.” The new entity will be called OlinHuntsman Corporation, positioning itself as a leading integrated North American chemicals company with a projected \$12.5 billion in pro forma 2025 revenues. This is a major consolidation move within the chemicals industry, with significant implications for shareholders, employees, and the competitive landscape.
Key Highlights of the Merger
- All-Stock Merger of Equals: Huntsman shareholders will receive 0.5476 Olin shares for each Huntsman share. Upon closing, Olin shareholders will own approximately 54.5% and Huntsman shareholders about 45.5% of the combined company.
- Combined Scale and Scope: The merged company, OlinHuntsman, will have expanded geographical reach, notably in the U.S. Gulf Coast, Europe, and Asia, and claim a structurally lower cost position.
- Synergies and Financial Benefits: The companies have identified over \$400 million in actionable cost synergies and integration benefits, with \$300 million expected to be realized within 24 months and the full amount by the end of year three. An additional \$100 million in raw material integration benefits is targeted for 2031. A further \$125 million in cash tax benefits are anticipated from the acceleration of Net Operating Losses.
- Vertical Integration: The merger will combine Olin’s upstream manufacturing and feedstock capabilities (e.g., chlorine, caustic soda) with Huntsman’s downstream products and formulation expertise, enabling improved margins, greater flexibility, and enhanced value creation throughout the cycle.
- Leadership and Governance: Ken Lane (current Olin CEO) will serve as CEO of OlinHuntsman, while Peter Huntsman (current Huntsman CEO) will become the non-executive Chairman. The board will have equal representation from both companies. The headquarters will be in The Woodlands, Texas.
- Winchester Ammunition Business: Olin’s Winchester segment will continue as a core business, maintaining its industry-leading position in sporting, law enforcement, and military markets.
Strategic and Financial Rationale
- Resilient, Value-Focused Company: Integration is designed to create a more resilient chemicals company, able to outperform through industry cycles and deliver stronger cash flows and growth options.
- Disciplined Capital Allocation: OlinHuntsman will focus on maintaining a strong balance sheet, sustaining dividends, near-term deleveraging, and directing excess cash toward shareholder returns and high-return growth projects.
- Merger Structure: The exchange ratio was set at the market using a 30-day volume-weighted average price as of June 12, 2026, providing a premium to Huntsman’s shareholders while smoothing volatility for Olin’s shareholders.
Timeline and Approvals
- The merger has been unanimously approved by both Boards of Directors.
- Closing is expected in the first half of 2027, subject to regulatory approvals and the approval of Olin and Huntsman shareholders.
Advisors
- Lazard is Olin’s financial advisor; Cravath, Swaine & Moore LLP and Sidley Austin LLP provide legal counsel.

Shareholder Impact & Potential Price-Sensitive Factors
- Significant Synergies and Cost Savings: Realization of substantial cost synergies and integration benefits (over \$400 million) is likely to be highly price-sensitive and could drive future profitability and share price appreciation.
- Premium to Huntsman Shareholders: The exchange ratio delivers a premium compared to historical averages, which could be viewed favorably by the market.
- Combined Company’s Financial Profile: The anticipated stronger cash flow, efficient cost structure, and disciplined capital allocation may support a higher valuation multiple.
- Regulatory and Execution Risks: The merger is subject to regulatory and shareholder approvals, and any delays or failure to close could negatively affect the share prices of both companies.
Important Considerations for Shareholders
- Integration and Realization Risks: While management is confident about synergies, any delays or underperformance in integration could reduce expected benefits.
- Leadership Continuity: Key management roles have been assigned, including a Chief Integration Officer to oversee synergy realization, potentially reducing integration risks.
- Forward-Looking Statements: Multiple forward-looking statements are present; actual results may vary materially due to numerous risks detailed in the companies’ filings, including economic conditions, regulatory approvals, and industry dynamics.
- Non-GAAP Financial Metrics: The synergy and pro forma financial estimates are non-GAAP measures and should not be considered in isolation from audited financials.
