As previously disclosed, on June 15, 2026, Olin Corporation, a Virginia corporation (“Olin”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Huntsman Corporation, a Delaware corporation (“Huntsman”), Olympus Merger Sub, Inc., a Delaware corporation and a direct wholly owned subsidiary of Olin (“First Merger Sub”), and Hook Merger Sub LLC, a Delaware limited liability company and a direct wholly owned subsidiary of Olin (“Second Merger Sub”), providing for, on the terms and subject to the conditions included in the Merger Agreement, the merger of equals business combination of Olin and Huntsman, either (a) through the merger of Huntsman with and into Olin, with Olin as the surviving entity (the “Direct Merger”), or (b) through (i) the merger of First Merger Sub with and into Huntsman (the “First Subsidiary Merger”), with Huntsman surviving as a direct, wholly owned subsidiary of Olin (the “Initial Surviving Company”), and (ii) immediately following the First Subsidiary Merger, and as part of the same overall transaction as the First Subsidiary Merger, the Initial Surviving Company will be merged with and into Second Merger Sub (the “Second Subsidiary Merger” and, together with the First Subsidiary Merger, the “Subsidiary Merger”), with Second Merger Sub surviving as a direct wholly owned subsidiary of Olin (we collectively refer to the Direct Merger and the Subsidiary Merger as the “Merger”).
In connection with the Merger, on July 2, 2026, Olin filed a registration statement on Form S-4 (File No. 333-297236) (as amended on July 10, 2026, the “Registration Statement”) with the Securities and Exchange Commission (the “SEC”). On July 13, 2026, the Registration Statement was declared effective by the SEC. Also on July 13, 2026, Olin and Huntsman each filed a definitive joint proxy statement/prospectus (the “Joint Proxy Statement/Prospectus”) with the SEC for the solicitation of proxies in connection with (i) the special meeting of Huntsman stockholders to be held on August 25, 2026 and (ii) the special meeting of Olin shareholders to be held on August 25, 2026, in each case, to vote upon matters necessary to complete the Merger and the other transactions contemplated by the Merger Agreement.
Two complaints have been filed in the Supreme Court of the State of New York by purported stockholders of Huntsman (the “Huntsman Complaints”) styled Jackson v. Huntsman Corporation et al., Index No. 654468/2026 (Sup. Ct. New York County July 30, 2026) and Thompson v. Huntsman Corporation et al., Index No. 654474/2026 (Sup. Ct. New York County July 30, 2026), against Huntsman and members of the Huntsman board relating to the Merger, alleging, among other things, that the Joint Proxy Statement/Prospectus omitted certain material information and asserting claims for negligent misrepresentation and concealment and negligence in violation of New York law. The Huntsman Complaints generally seek, among other things, (i) to enjoin the Huntsman stockholder vote or the Merger until defendants make corrective disclosures and (ii) in the event the stockholder vote and Merger is consummated, to recover damages therein. Additionally, Huntsman has received certain demand letters (collectively, the “Huntsman Demands”) from purported Huntsman stockholders generally alleging material omissions or misstatements in the disclosures in the preliminary joint proxy statement/prospectus filed by Olin with the SEC on July 2, 2026 or the Joint Proxy Statement/Prospectus and demanding that Huntsman file corrective disclosures prior to the special meeting of Huntsman stockholders.
Separately, as of the date hereof, a complaint has been filed in the Circuit Court of Cole County, Missouri by purported shareholders of Olin (the “Olin Complaint” and, together with the Huntsman Complaints, the “Complaints”) styled Palmer v. Babcock, et al., No. 26AC-CC00452 (Mo. Cir. Ct. Cole County Aug. 11, 2026), against Olin, members of the Olin board, and Huntsman relating to the Merger, alleging, among other things, that defendants violated the Missouri Securities Act and that the Joint Proxy Statement/Prospectus omitted certain material information and asserting claims for negligent misrepresentation and concealment and negligence in violation of Missouri law.
Olin, Huntsman and the other defendants believe that the allegations in the Complaints and the Huntsman Demands are without merit, that the Joint Proxy Statement/Prospectus fully complies with the Exchange Act and all other applicable law, and that no further disclosure is required. However, solely in order to avoid the risk of delaying or otherwise adversely affecting the consummation of the Merger and to minimize the expense and distraction of defending such actions, Olin hereby voluntarily amends and supplements the Joint Proxy Statement/Prospectus as set forth in this Current Report on Form 8-K. Nothing in the supplemental disclosures set forth below should be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein.
It is possible that additional, similar complaints may be filed, that the complaints described above may be amended or that additional demand letters will be received by Olin and/or Huntsman. If this occurs, Olin does not intend to announce the filing or receipt of each additional, similar complaint or demand letter or any amended complaint unless required by law.
2
The Olin board continues to unanimously recommend that Olin shareholders vote “FOR” the Olin direct merger proposal, “FOR” the Olin subsidiary merger proposal, “FOR” the Olin advisory compensation proposal and “FOR” the Olin adjournment proposal, each as defined and described in the Joint Proxy Statement/Prospectus.

For purposes of its analyses, Citi assumed approximately 178 million fully diluted shares of Huntsman common stock and approximately 118 million fully diluted shares of Olin common stock based on information provided by Huntsman management and Olin management, respectively.
The disclosure that is under the heading “Discounted Cash Flow Analyses” is hereby supplemented by adding the underlined disclosure and deleting the text that is struck through under that heading on pages 112 and 113 of the Joint Proxy Statement/Prospectus:
Huntsman. With respect to Citi’s discounted cash flow analysis of Huntsman, Citi calculated the estimated present value of the unlevered, after-tax free cash flows that Huntsman was forecasted to generate during the last three quarters of calendar year 2026 through calendar year 2030, based on the Huntsman standalone projections. The estimated range of terminal values of Huntsman was calculated by applying a selected range of perpetuity growth rates of 1.5% to 2.5% to Huntsman’s estimated unlevered, after-tax free cash flows for the terminal year. The forecasted unlevered, after-tax free cash flows for Huntsman for the last three quarters of calendar year 2026 through calendar year 2030 and the derived range of terminal values were then discounted to present values, as of March 31, 2026, using a mid-year convention and discount rates ranging from 8.5% to 9.4%, which Citi derived based on estimates of Huntsman’s weighted average cost of capital taking into account, among other things, a risk free rate, market risk premiums and betas. For purposes of this analysis, adjusted earnings before interest and taxes (“Adj.
4
EBIT”) was calculated as adjusted earning before interest, taxes, depreciation and amortization (burdened by stock-based compensation), which we refer to in this section as “Adj. EBITDA,” less depreciation and amortization, and unlevered free cash flows were calculated as Adj. EBIT less taxes, plus depreciation and amortization, less capital expenditures, plus or minus change in net working capital, and less certain other cash restructuring and integration payments, pension contribution in excess of EBITDA, non-controlling interest contribution, maintenance and other items. The present values of the unlevered, after-tax free cash flows and the range of derived terminal values, together with the estimated present value of certain tax attributes of Huntsman (which Citi estimated to be between approximately $145 million and $156 million based on information provided by Huntsman management), were then adjusted for Huntsman’s net approximately $2,067 million of debt and other balance sheet items$369 million of cash and cash equivalents as of March 31, 2026, as provided by Huntsman’s management, and then divided by the number of fully diluted shares of Huntsman common stock as derived from information provided by Huntsman’s management using the treasury stock method to derive an implied reference range of equity values for the Huntsman common stock of approximately $15.20 to $21.80 per share (rounded to the nearest $0.05). Citi noted that the estimated value of the tax attributes was approximately $0.82 to $0.88 per share.
Olin. With respect to Citi’s discounted cash flow analysis of Olin, Citi calculated the estimated present value of the unlevered, after-tax free cash flows that Olin was forecasted to generate during the last three quarters of calendar year 2026 through calendar year 2031, based on the Olin standalone projections. The estimated range of terminal values of Olin was calculated by applying a selected range of perpetuity growth rates of 1.5% to 2.5% to Olin’s estimated unlevered, after-tax free cash flows for the terminal year. The forecasted unlevered, after-tax free cash flows for Olin for the last three quarters of calendar year 2026 through calendar year 2031 and the derived range of terminal values were then discounted to present values, as of March 31, 2026, using a mid-year convention and discount rates ranging from 8.9% to 9.9%, which Citi derived based on estimates of Olin’s weighted average cost of capital taking into account, among other things, a risk free rate, market risk premiums and betas. For purposes of this analysis, unlevered free cash flows were calculated as Adj. EBIT less taxes, plus depreciation and amortization, less capital expenditures, plus or minus change in net working capital, and less restructuring and legacy litigation costs. The present values of the unlevered, after-tax free cash flows and the range of derived terminal values were then adjusted for Olin’s net debt and other balance sheet items approximately $3,016 million of debt, $192 million of cash and cash equivalents, $0.4 million non-controlling interest and $14 million of settled stock awards as of March 31, 2026, as provided by Olin’s management, and then divided by the number of fully diluted shares of Olin common stock derived from information provided by Olin management using the treasury stock method to derive an implied reference range of equity values for the Olin common stock of approximately $41.40 to $56.30 per share (rounded to the nearest $0.05).
The disclosure that is under the heading “Selected Public Companies Analyses” is hereby supplemented by adding the underlined disclosure, deleting the text that is struck through and adding the underlined figures and disclosure in the below tables under that heading on pages 113 and 114 of the Joint Proxy Statement/Prospectus:
Huntsman. In its selected public companies analysis of Huntsman, Citi reviewed certain financial and stock market information relating to Huntsman and the following five selected entities that Citi considered generally relevant as publicly traded companies with operations in the specialty and commodity chemicals industry, which are collectively referred to in this section as the “Huntsman selected companies”:
| • | Celanese Corporation |
| • | Eastman Chemical Company |
| • | Olin Corporation |
| • | The Chemours Company |
| • | Tronox Holdings plc |
Citi reviewed, among other information, estimated firm value, calculated as equity value (based on closing stock prices of the Huntsman selected companies on June 12, 2026) plus debt, less cash and cash equivalents and other adjustments, which we refer to in this section as “FV,” as a multiple of Adj. EBITDA for calendar year 2026 and calendar year 2027 (burdened by stock-based compensation). Financial data of the Huntsman selected companies were based on publicly available consensus estimates of FactSet analysts, public filings and other publicly available information. Financial data of Huntsman was based on the Huntsman standalone projections, publicly available consensus estimates of FactSet analysts, public filings and other publicly available information.

The overall low to high calendar year 2026 and calendar year 2027 estimated FV to adjusted EBITDA multiples observed for the Huntsman selected companies were as follows:
| • | calendar year 2026 estimated FV to Adj. EBITDA multiples: 8.0x to 13.1x (with a median of 8.6x); and |
| • | calendar year 2027 estimated FV to Adj. EBITDA multiples: 7.2x to 9.7x (with a median of 7.9x). |
Citi then applied a selected range of calendar year 2026 estimated FV to Adj. EBITDA multiples of 8.6x to 13.1x and a selected range of calendar year 2027 estimated FV to Adj. EBITDA multiples of 7.9x to 9.7x, in each case reflecting the median to high multiples of the Huntsman selected companies and based on Citi’s professional judgment and experience, to the corresponding Adj. EBITDA of Huntsman of $346 million (calendar year 2026) and $501 million (calendar year 2027) based on the Huntsman standalone projections.
From this analysis, using its professional judgment, Citi derived implied equity value reference ranges for the Huntsman common stock (rounded to the nearest $0.05) of $7.20 to $15.90 per share based on calendar year 2026 estimated Adj. EBITDA and $12.70 to $17.60 per share based on calendar year 2027 estimated Adj. EBITDA.
Olin. In its selected public companies analysis of Olin, Citi reviewed certain financial and stock market information relating to Olin and the following six selected entities that Citi considered generally relevant as publicly traded companies with operations in the specialty and commodity chemicals industry, which are collectively referred to in this section as the “Olin selected companies”:
| • | Dow Inc. |
| • | Huntsman Corporation |
| • | LyondellBasell Industries N.V. |

Financial data of the Olin selected companies were based on publicly available consensus estimates of FactSet analysts, public filings and other publicly available information. Financial data of Olin was based on the Olin standalone projections, publicly available consensus estimates of FactSet analysts, public filings and other publicly available information.
The overall low to high calendar year 2026 and calendar year 2027 estimated FV to Adj. EBITDA multiples observed for the Olin selected companies were 5.7x to 13.1x (calendar year 2026, with a median of 7.9x) and 6.7x to 10.2x (calendar year 2027, with a median of 7.5x).

The disclosure that is under the heading “Huntsman Discounted Equity Value Analysis” is hereby supplemented by adding the underlined disclosure under that heading on pages 122 and 123 of the Joint Proxy Statement/Prospectus:
To calculate the discounted equity value for Huntsman, Morgan Stanley utilized estimated 2028 Adj. EBITDA (“2028E Adj. EBITDA”) from the Huntsman standalone projections. Based upon the application of its professional judgment and experience, Morgan Stanley applied a range of multiples of aggregate value to next-twelve-months (“NTM”) estimated Adj. EBITDA of 5.5x to 7.5x derived from the AV/Cycle Average Adj. EBITDA multiples described under “Comparable Companies Analysis” above, added the cumulative value of Huntsman’s projected dividends of $0.0875 per share per quarter (based on the Huntsman standalone projections), and discounted the resulting values to present value at a discount rate of 11.0%, which rate was selected based on the estimated cost of equity for Huntsman determined using the capital asset pricing model taking into account, among other things, a risk free rate, a market risk premium and a beta. Based on this analysis, Morgan Stanley derived the following range of implied equity value per share of Huntsman common stock on a fully diluted basis (rounded to the nearest $0.25):
| AV / 2028E Adj. EBITDA | Implied Equity Value Per Share Range | |
| Huntsman Management Case |
$12.00 - $19.25 |
The disclosure that is under the heading “Olin Discounted Equity Value Analysis” is hereby supplemented by adding the underlined disclosure under that heading on page 123 of the Joint Proxy Statement/Prospectus:
To calculate the discounted equity value for Olin, Morgan Stanley utilized 2028E Adj. EBITDA from the Olin standalone projections. Based upon the application of its professional judgment and experience, Morgan Stanley applied a range of multiples of aggregate value to NTM estimated Adj. EBITDA of 5.5x to 7.5x derived from the AV/Cycle Average Adj. EBITDA multiples described under “—Comparable Companies Analysis” above, added the cumulative value of Olin’s projected dividends of $0.20 per share per quarter (based on the Wall Street consensus research estimates), and discounted the resulting values to present value at a discount rate of 10.5%, which rate was selected based on the estimated cost of equity for Olin determined using the capital asset pricing model taking into account, among other things, a risk free rate, a market risk premium and a beta. Based on this analysis, Morgan Stanley derived the following range of implied equity value per share of Olin common stock on a fully diluted basis (rounded to the nearest $0.25):
| AV / NTM 2028E EBITDA | Implied Equity Value Per Share Range | |
| Olin Management Case |
$29.00 - $45.75 |

The disclosure that is under the heading “Huntsman Discounted Cash Flow Analysis” is hereby supplemented by adding the underlined disclosure under that heading on page 124 of the Joint Proxy Statement/Prospectus:
Morgan Stanley calculated terminal values for Huntsman by applying a range of perpetuity growth rates of 1.0% to 2.0%, based on Morgan Stanley’s professional judgment. Morgan Stanley then discounted the unlevered free cash flows and terminal value to present value as of March 31, 2026 using a mid-year convention and a range of discount rates from 7.1% to 8.3%, which were selected based on Morgan Stanley’s professional judgment to reflect an estimate of Huntsman’s weighted average cost of capital based on the capital asset pricing model and other factors taking into account, among other things, a risk free rate, market risk premiums and betas. The resulting aggregate value was then increased by the present value of Huntsman’s estimated net operating loss carryforwards (which Morgan Stanley estimated to be between approximately $159 million and $175 million based on information provided by Huntsman management) and adjusted for actual net debt of Huntsman of approximately $1,698 million as of March 31, 2026 to derive the implied equity value. To calculate the implied per share equity value, Morgan Stanley then divided the implied equity value by the number of fully diluted shares of Huntsman common stock outstanding as of June 12, 2026 derived from information provided by Huntsman management using the treasury stock method.
The disclosure that is under the heading “Olin Discounted Cash Flow Analysis” is hereby supplemented by adding the underlined disclosure under that heading on page 124 of the Joint Proxy Statement/Prospectus:
Morgan Stanley calculated terminal values for Olin by applying a range of perpetuity growth rates of 0.5% to 1.5%, based on Morgan Stanley’s professional judgment. Morgan Stanley then discounted the unlevered free cash flows and terminal value to present value as of March 31, 2026 using a mid-year convention and a range of discount rates from 6.8% to 7.8%, which were selected based on Morgan Stanley’s professional judgment to reflect an estimate of Olin’s weighted average cost of capital based on the capital asset pricing model and other factors taking into account, among other things, a risk free rate, market risk premiums and betas. The resulting aggregate value was then adjusted for actual net debt of Olin of approximately $2,838 million as of March 31, 2026 to derive the implied equity value. To calculate the implied per share equity value, Morgan Stanley then divided the implied equity value by the number of fully diluted shares of Olin common stock outstanding as of June 12, 2026 derived from information provided by Olin management using the treasury stock method.
The disclosure that is under the heading “Huntsman Standalone Projections” is hereby supplemented by adding the underlined disclosure under that heading on page 132 of the Joint Proxy Statement/Prospectus:
The Huntsman standalone projections were prepared by Huntsman management in connection with the evaluation of a potential transaction by the Huntsman board. Initial Huntsman standalone projections were prepared and provided to the Huntsman board on April 29, 2026 (the “initial Huntsman standalone projections”). Huntsman management made certain adjustments to such projections (including to the free cash flow projections) and adjusted and extrapolated such forecasts, and Huntsman management provided to the Huntsman board such adjusted and extrapolated projections in June 2026, which were approved by the Huntsman board for use and were used and relied on at the direction of the Huntsman board by Citi and Morgan Stanley in connection with their respective financial analyses and opinions. Except with respect to unlevered free cash flow, the Huntsman standalone projections were provided to Olin. The Huntsman standalone projections were based on numerous estimates, expectations, beliefs, opinions and assumptions with respect to Huntsman’s business, including its results of operations and financial condition, customer requirements and competition, and with respect to general business, economic, market, regulatory and financial conditions and other future events, all of which are difficult to predict and many of which are beyond Huntsman’s control and may not be realized. Huntsman management believes that the estimates, expectations, beliefs, opinions and assumptions used as a basis for the Huntsman standalone projections were reasonable based on the information available to Huntsman management at the time prepared. However, the Huntsman standalone projections are not a guarantee of actual future performance. The future financial results of Huntsman’s business may differ materially from those expressed in the Huntsman standalone projections due to various factors, including factors that are beyond Huntsman’s ability to control or predict.
The differences between the initial Huntsman standalone projections and the Huntsman standalone projections did not reflect any material change in Huntsman management’s view of the business or its operating outlook. Rather, the updates were primarily mechanical in nature and related to certain non-operating assumptions, changes in the presentation, and calculation of certain cash flow metrics.
Revenue projections for 2027E through 2030E were unchanged between the initial Huntsman projections and the Huntsman standalone projections, while 2026E revenue was reduced from $6,287 million to $6,150 million. Adjusted EBITDA was also effectively unchanged, with the only revisions consisting of a $1 million decrease in 2029E Adjusted EBITDA (from $915 million to $914 million) and a $1 million decrease in 2030E Adjusted EBITDA (from $1,161 million to $1,160 million). Capital expenditures, depreciation and amortization, and change in net working capital assumptions remained consistent across the two versions.
Beyond these largely unchanged operating assumptions, the additional updates primarily related to non-operating cash flow assumptions rather than changes to Huntsman’s business outlook. Key changes included modest adjustments to cash tax rates (~1% per annum), lower projected pension contributions over the forecast period, and an updated definition of unlevered free cash flow to reflect the treatment of dividends and minority interest contributions. As a result, differences in projected unlevered free cash flow were driven by these assumption and methodology changes, rather than any material change in management’s expectations for the business.

Important Note about Combined and Non-GAAP Financial Information
The financial information for the combined businesses of Olin and Huntsman is based on management’s estimates, assumptions and projections and has not been prepared in conformance with the applicable requirements of Regulation S-X relating to pro forma financial information, and the required pro forma adjustments have not been applied and are not reflected therein. This information is provided for illustrative purposes only and should not be considered in isolation from, or as a substitute for, the historical financial statements of Olin or Huntsman. These measures are provided for illustrative purposes and are based on an arithmetic sum of the relevant historical financial measures of Olin and Huntsman. These measures do not reflect what the combined company’s financial condition or results of operations would have been had the proposed transaction occurred on or prior to the dates indicated. Various factors could cause actual future results to differ materially from those currently estimated by management, including, but not limited to, the risks described above and in each of Olin’s and Huntsman’s respective filings with the SEC.
This Current Report on Form 8-K also includes certain financial measures not calculated in accordance with U.S. generally accepted accounting principles (“GAAP”), such as synergies and integration benefits. Non-GAAP financial measures have limitations as an analytical tool and are not meant to be considered in isolation from, or as a substitute for, the comparable GAAP measures. There are limitations to non-GAAP financial measures because they are not prepared in accordance with GAAP and may not be comparable to similarly titled measures of other companies due to potential differences in methods of calculation and items being excluded. Olin and Huntsman caution you not to place undue reliance on these non-GAAP financial measures.
