Huntsman CORP (HUN) SEC Filings, May-Jun 2026

Huntsman Corporation provided customer and supplier communications about its proposed merger of equals with Olin Corporation, describing the transaction as a definitive agreement and stating that operations remain separate until closing. The message emphasizes continuity of service and that updates will be provided through official channels.

The communication includes the legal caution that transaction materials will be filed with the SEC, references an anticipated Olin Form S-4 containing a joint proxy statement/prospectus, and lists SEC filings and dates for background on directors and officers.

Huntsman Corporation agreed to combine businesses with Olin Corporation in a merger of equals announced on June 16, 2026. The companies target closing in 1H 2027 and plan a combined workforce of approximately 14,000 associates. Until required approvals and closing, both companies will operate independently and employees should continue normal duties. The communication states some role duplications are expected as part of targeted synergies and that Huntsman associates will receive compensation no less favorable and substantially comparable benefits for at least 12 months after closing. The parties intend to file an Olin registration statement on Form S-4 including a joint proxy statement/prospectus and urge shareholders to read those materials when filed.

Olin Corporation and Huntsman Corporation presented an investor call describing an all-stock merger of equals to form OlinHuntsman Corporation. Under the agreement, Huntsman shareholders will receive 0.576 Olin shares per Huntsman share, producing ~54.5% Olin / 45.5% Huntsman ownership. The companies said the combined business would be a greater-than-$12 billion chemicals company, with a 2025 pro forma revenue of $12.5 billion and pro forma adjusted EBITDA of about $1.3 billion including expected cost synergies. Management identified more than $400 million of cost synergies and integration benefits ($300 million near-term; an incremental $100 million tied to contracts expiring in 2031) and estimated cash costs to achieve synergies of approximately $150 million to $200 million. The transaction is expected to close in the first half of 2027, subject to regulatory and shareholder approvals. Management emphasized deleveraging, a stable dividend policy, maintenance capital of about $400 million per year, and use of free cash flow for priority allocation.

Huntsman Corporation announced that its Board unanimously approved an agreement to merge with Olin Corporation in an all‑stock transaction. Management describes the deal as combining complementary strengths to create a larger, more competitive company. The communication says regulatory review and shareholder approval are required and currently anticipates the process may run until sometime within the first half of 2027. The company directed associates to a shareholder webcast and internal town halls and noted filings with the SEC, including an Olin registration statement on Form S‑4 that will include a joint proxy statement/prospectus.

Huntsman Corporation announced a proposed all-stock merger of equals with Olin Corporation to form OlinHuntsman, a North American chemicals company with more than $12+ billion in combined scale. Huntsman shareholders will receive 0.5476 Olin shares for each Huntsman share, giving Olin shareholders about 54.5% and Huntsman shareholders about 45.5% of the combined company.

The transaction targets over $400 million in identifiable cost synergies and integration benefits. Ken Lane, Olin’s CEO, will lead OlinHuntsman, while Peter Huntsman will be non-executive Chairman. The deal has been unanimously approved by both boards and is expected to close in the first half of 2027, subject to regulatory and shareholder approvals.

Huntsman CORP Division President Steen Weien Hansen reported a small, routine share disposition tied to tax withholding. On vesting of restricted stock, 883 shares of common stock were automatically withheld at $14.99 per share to satisfy tax obligations, rather than sold on the open market.

After this tax-withholding disposition, Hansen directly holds 177,944 shares of Huntsman common stock. Because this F-code transaction reflects mandatory tax withholding on equity compensation, it carries little informational value about his view of the stock.

Huntsman Corporation reported the results of its 2026 Annual Meeting of Stockholders held on April 29, 2026. All nominated directors were re-elected to serve until the 2027 annual meeting, based on strong support from shares present or represented by proxy.

Stockholders approved, on an advisory basis, the compensation of the company’s named executive officers, and ratified the appointment of Deloitte & Touche LLP as independent registered public accounting firm for the fiscal year ending December 31, 2026. A stockholder proposal requesting an independent board chair policy did not receive sufficient votes for approval.

Huntsman Corporation reported a net loss for the quarter ended March 31, 2026 as operating conditions softened and one-time benefits seen last year did not recur. Total revenues were $1,420 million, slightly up from $1,410 million a year earlier, with Polyurethanes, Performance Products and Advanced Materials all contributing.

Higher cost of goods sold and increased restructuring, impairment and plant closing costs reduced profitability, and 2025 had benefited from income associated with a litigation matter that did not repeat. Net loss attributable to Huntsman Corporation widened to $53 million from $5 million, with basic and diluted loss per share at $(0.31) versus $(0.03).

Operating cash flow from continuing operations was a use of $53 million, compared with a use of $71 million in the prior-year period, reflecting working capital movements and noncash items. Cash and cash equivalents were $369 million and total debt was $2,056 million, including a new $800 million secured revolving credit facility of which $367 million was drawn.
