Brian Rudick

Senior Vice President, General Counsel & Corporate Secretary

At the effective time of the Mergers, each Element Solutions restricted stock unit (“RSU”) held by an individual who is party to an Element Solutions Change in Control Agreement or a non-employee director and each Element Solutions RSU granted in 2024 and each Element Solutions performance stock unit (“PSU”) held by an individual who is party to an Element Solutions Change in Control Agreement and each Element Solutions PSU granted in 2024, whether vested or unvested, will accelerate and vest in full (with the number of shares subject to each such Element Solutions PSU determined based on performance deemed achieved at (i) 200% of the target performance level for awards granted in 2024 and 2026 and (ii) 300% of the target performance level for awards granted in 2025) and be canceled and converted into the right to receive the Merger Consideration, subject to applicable tax withholdings.

Each other outstanding and unvested Element Solutions RSU and Element Solutions PSU, except as provided otherwise in the Element Solutions Disclosure Schedule, will be assumed and converted into a number of Solstice RSUs, rounded up to the nearest whole share (each, a “Converted RSU” or “Converted PSU,” as applicable), equal to the product of the number of shares of Element Solutions Common Stock subject to such award (with performance for Converted PSUs deemed achieved at 300% of the target performance level for 2025 grants and 200% of the target performance level for 2026 grants), multiplied by the Conversion Ratio. Each Converted RSU and Converted PSU will continue to vest on the same schedule as the corresponding Element Solutions RSU and Element Solutions PSU, subject to continued service, and will be settled in Solstice Common Stock upon vesting, subject to applicable tax withholdings; provided that if any holder is terminated without Cause or resigns for Good Reason, such holder’s Converted RSUs or Converted PSUs will immediately vest in full. The “Conversion Ratio” is equal to the sum of (i) the Exchange Ratio plus (ii) the quotient obtained by dividing the Per Share Cash Amount by the volume weighted average trading price of a share of Solstice Common Stock on the Nasdaq Stock Market for the five consecutive trading days ending on the trading day immediately preceding the Closing Date (the “Parent Measurement Price”).

In addition, each Element Solutions option with a per share exercise price less than the Company Measurement Price, whether vested or unvested, that is outstanding immediately prior to the First Merger Effective Time will accelerate and vest in full and be canceled and converted into a number of shares of Element Solutions Common Stock equal to the product of (i) the number of shares of Element Solutions Common Stock applicable to such Element Solutions option, multiplied by (ii) the difference between (a) the Company Measurement Price and (b) the per share exercise price applicable to such Element Solutions option, divided by the Company Measurement Price, with any fractional shares rounded up to the nearest whole share, with such amount in turn converted into the right to receive the Merger Consideration, subject to applicable tax withholdings. Each Element Solutions option with a per share exercise price equal to or greater than the Company Measurement Price will be canceled for no consideration. “Company Measurement Price” means an amount equal to the volume weighted average trading price of a share of Element Solutions Common Stock on the New York Stock Exchange for the five consecutive trading days ending on the trading day immediately preceding the Closing Date.

Representations, Warranties and Covenants

The Merger Agreement contains customary representations and warranties of Solstice and the Merger Subs, on the one hand, and Element Solutions, on the other hand, relating to their respective businesses and public filings, among other matters, in each case generally subject to certain customary qualifications. In addition, the Merger Agreement provides for customary pre-closing covenants, including covenants by each of Solstice and Element Solutions to use reasonable best efforts to (i) conduct its business in the ordinary course in all material respects during the period between the signing of the Merger Agreement and the closing of the Mergers (subject to certain exceptions), (ii) refrain from taking certain actions without the other party’s consent and (iii) cooperate and use reasonable best efforts with respect to seeking regulatory approvals (subject to certain specified limitations). Both Solstice and Element Solutions have agreed not to solicit proposals from, provide information to, or enter into discussions with, third parties, in each case, relating to specified alternative transaction proposals.

Notwithstanding the restrictions related to alternative transactions, prior to obtaining the approval of their respective stockholders, each of Solstice and Element Solutions may under certain circumstances provide non-public information to, and participate in discussions with, third parties with respect to any unsolicited alternative transaction proposals that the Solstice Board or the Element Solutions Board, as applicable, has, among other things, determined (i) did not result from a material breach of its non-solicitation obligations under the Merger Agreement and (ii) constitutes or would reasonably be expected to result in a Superior Company Proposal or a Superior Parent Proposal, as applicable, after taking into account the advice of an independent financial advisor and its outside legal counsel. A “Superior Parent Proposal” or a “Superior Company Proposal” is an unsolicited, bona fide written offer by a third party concerning an alternative transaction acquisition proposal that did not result from a material breach of the relevant provisions of the Merger Agreement and is on terms and conditions that the Element Solutions Board or Solstice Board, as applicable, has determined in good faith, after taking into account the advice of an independent financial advisor and its outside legal counsel and the likelihood and timing of consummation of the transaction contemplated by such offer, to be more favorable from a financial point of view to such party’s stockholders than the Mergers.

Prior to obtaining the relevant stockholder approval, the Element Solutions Board or the Solstice Board, as applicable, may change its recommendation to its stockholders in connection with the Mergers, subject to complying with certain notice and other specified conditions contained in the Merger Agreement, including giving the other party an opportunity to propose revisions to the terms of the Merger Agreement during a match right period.

In addition, Solstice has agreed to take all necessary actions to cause, effective as of the First Merger Effective Time, the Solstice Board to consist of eleven directors comprising eight directors of Solstice as of immediately prior to the First Merger Effective Time and three Element Solutions designees from the existing Element Solutions Board.

Conditions to the Transactions

Consummation of the Mergers is subject to the satisfaction or waiver of certain conditions, including, among others, (a) adoption of the Merger Agreement by Element Solutions’ stockholders; (b) the approval of the issuance of Solstice Common Stock in the Mergers (the “Solstice Stock Issuance”) by Solstice’s stockholders; (c) the effectiveness of a registration statement on Form S-4 to be filed with the SEC by Solstice in connection with the issuance of Solstice Common Stock in the Mergers; (d) the approval for listing of the shares of Solstice Common Stock to be issued in the Mergers on the Nasdaq Stock Market; and (e) the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), and certain other regulatory approvals. The obligation of each party to consummate the Mergers is also conditioned upon, among other things, the accuracy of the other party’s representations and warranties (subject to certain materiality exceptions), the other party having performed in all material respects its covenants and obligations under the Merger Agreement, the absence of a “Material Adverse Effect” on the other party (as defined in the Merger Agreement), and the receipt by such party of an opinion of counsel to the effect that the Mergers will qualify for their intended tax treatment.

Termination

The Merger Agreement also provides the parties with rights to terminate the Merger Agreement in certain circumstances, including (i) by mutual written consent of Solstice and Element Solutions; (ii) by either party if the Mergers have not been consummated by July 6, 2027 (the “End Date”), subject to an automatic extension until January 5, 2028 under certain circumstances for the purposes of obtaining certain regulatory approvals; (iii) by either party if a governmental body of competent jurisdiction issues a final and non-appealable order permanently restraining, enjoining or otherwise prohibiting the Mergers, or if a law is enacted that makes consummation of the Mergers illegal; (iv) by either party if Element Solutions’ stockholders fail to adopt the Merger Agreement or Solstice’s stockholders fail to approve the Solstice Stock Issuance; (v) by either party in the event of certain uncured breaches by the other party of its representations, warranties or covenants (subject, in each case, to a 30-day cure period for curable breaches, provided that the terminating party is not then itself in material breach); (vi) by Element Solutions if the consent required to be provided by Honeywell International Inc. (“Honeywell”) pursuant to the Tax Matters Agreement (as defined in the Merger Agreement) (the “RemainCo Consent”) is withdrawn, Honeywell initiates a RemainCo Action, or the RemainCo Consent is otherwise not in full force or effect (subject to a waiting period equal to the earlier of 60 days or one business day prior to the End Date); (vii) by Solstice or Element Solutions, within ten business days of the Solstice Board or Element Solutions Board, as applicable, changing its recommendation in connection with the Mergers or having failed to make or reaffirm such recommendation in certain circumstances; or (viii) by Solstice or Element Solutions prior to obtaining the applicable stockholder approval, to enter into a definitive agreement with respect to a Superior Parent Proposal or a Superior Company Proposal, as applicable, in each case subject to compliance with the applicable provisions of the Merger Agreement.

If the Merger Agreement is terminated under certain circumstances, Element Solutions would be obligated to pay Solstice a termination fee of $376,000,000 (the “Element Solutions Termination Fee”) in cash. The Element Solutions Termination Fee would be payable, among other circumstances, if (i) the Merger Agreement is terminated by Solstice following the Element Solutions Board changing or withdrawing its recommendation regarding the Mergers; (ii) Element Solutions terminates the Merger Agreement to enter into a definitive agreement with respect to a superior proposal; or (iii) following the public disclosure of an alternative acquisition proposal with respect to Element Solutions, the Merger Agreement is terminated for failure to obtain Element Solutions’ stockholder approval and, within 12 months after such termination, Element Solutions enters into a definitive agreement for, or consummates, certain alternative acquisition transactions.

If the Merger Agreement is terminated under certain circumstances, Solstice would be obligated to pay Element Solutions a termination fee of $385,000,000 (the “Solstice Termination Fee”) in cash. The Solstice Termination Fee would be payable, among other circumstances, if (i) the Merger Agreement is terminated by Element Solutions following the Solstice Board changing or withdrawing its recommendation regarding the Solstice Stock Issuance; (ii) Solstice terminates the Merger Agreement to enter into a definitive agreement with respect to a superior proposal; or (iii) following the public disclosure of an alternative acquisition proposal with respect to Solstice, the Merger Agreement is terminated for failure to obtain Solstice’s stockholder approval and, within 12 months after such termination, Solstice enters into a definitive agreement for, or consummates, certain alternative acquisition transactions.

In addition, if Element Solutions terminates the Merger Agreement due to the withdrawal of the RemainCo Consent or the initiation of certain legal proceedings by Honeywell, and Solstice has delivered a valid unqualified tax opinion to Element Solutions and Honeywell confirming that the Mergers will not cause Honeywell to recognize gain under Section 355(e) of the Internal Revenue Code of 1986, as amended, which remains in full force and effect prior to such termination, then Solstice would be obligated to pay Element Solutions a termination fee of $385,000,000 in cash. If Element Solutions terminates the Merger Agreement due to the withdrawal of the RemainCo Consent or the initiation of certain legal proceedings by Honeywell, and Solstice fails to deliver such a valid unqualified tax opinion prior to such termination, then Solstice would be obligated to pay Element Solutions a termination fee of $513,000,000 in cash. No termination fee would be payable by Solstice in either case if the withdrawal of the RemainCo Consent or such legal proceedings result from a breach by Element Solutions of its tax representation letter delivered in connection with its own unqualified tax opinion that the Mergers will qualify for their intended tax treatment.

In no event will either party be required to pay its applicable termination fee on more than one occasion.

Except as otherwise expressly provided in the Merger Agreement, all fees and expenses incurred in connection with the Merger Agreement and the transactions contemplated thereby will be paid by the party incurring such fees and expenses, whether or not the Mergers are consummated, except that Solstice will bear all filing fees incurred by the parties in connection with the premerger notification and report forms under the HSR Act and filings under applicable foreign antitrust, competition or foreign direct investment laws.

The foregoing description of the Merger Agreement is qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which is attached as Exhibit 2.1 to this Current Report on Form 8-K (the “Report”) and is incorporated herein by reference.

The Merger Agreement has been attached to provide investors with information regarding its terms. It is not intended to provide any other factual information about the parties. In particular, the assertions embodied in the representations and warranties contained in the Merger Agreement are qualified by information in confidential disclosure schedules provided by each party in connection with the signing of the Merger Agreement. These confidential disclosure schedules contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the Merger Agreement. Moreover, certain representations and warranties in the Merger Agreement were used for the purpose of allocating risk between the parties rather than establishing matters as facts. Investors are not third-party beneficiaries under the Merger Agreement and should not rely on the representations, warranties, and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the parties thereto or any of their respective subsidiaries or affiliates. Moreover, information concerning the subject matter of representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the parties’ public disclosures. Accordingly, you should not rely on the representations and warranties in the Merger Agreement as characterizations of the actual state of facts about the parties.

Item 8.01 Other Events.

Debt Financing

In connection with entering into the Merger Agreement, on July 6, 2026, Solstice entered into a commitment letter (the “Bridge Commitment Letter”) with Goldman Sachs Bank USA and Goldman Sachs Lending Partners LLC (the “Commitment Parties”), pursuant to which the Commitment Parties have agreed, subject to the terms and conditions set forth therein, to provide Solstice with certain committed financing in order to fund all or a portion of the cash consideration payable at the closing of the Transactions pursuant to the Merger Agreement, to consummate the refinancing of certain existing indebtedness of Element Solutions and to pay related fees and expenses.

The Bridge Commitment Letter provides for (i) a first lien senior secured 364-day bridge term loan credit facility (the “Bridge Facility”) in an aggregate principal amount of up to $4,685,000,000 and (ii) a $1,000,000,000 backstop senior secured revolving credit facility (the “Backstop Revolving Facility” and together with the Bridge Facility, the “Facilities”), only to be established in the event that a proposed amendment to Solstice’s existing revolving credit agreement required to permit the Bridge Facility does not become effective on or prior to the closing of the Transactions. The Bridge Facility is intended to be available to Solstice to finance, together with other sources of funds, the acquisition, the refinancing of certain existing indebtedness of Element Solutions and related fees and expenses in connection with the Transactions, in the event that Solstice has not obtained the Permanent Financing (as defined below) on or prior to the closing of the Transactions. The Facilities are subject to customary conditions precedent to funding, including the consummation of the Transactions in all material respects in accordance with the terms of the Merger Agreement and other customary funding conditions for facilities of this type. The Facilities contain customary representations, warranties, covenants and indemnification provisions for transactions of this nature.

The Bridge Commitment Letter also contemplates that Solstice will seek to obtain permanent financing in the form of a senior secured term loan B facility and unsecured notes in public or private offering(s) prior to the closing of the Transactions (collectively, the “Permanent Financing”). Commitments under the Bridge Facility will be reduced by the amount of any Permanent Financing as well as certain other events. The receipt of financing by Solstice is not a condition to Solstice’s obligation to consummate the Transactions.

Voting Agreement

In connection with the execution of the Merger Agreement, on July 6, 2026, Solstice entered into a voting and support agreement (the “Voting Agreement”) with Sir Martin E. Franklin (the “Supporting Stockholder”), under which the Supporting Stockholder agreed, among other things, to vote, or cause to be voted, all of the shares of Element Solutions Common Stock, directly or beneficially owned by such Supporting Stockholder, as of the applicable record date and as of the stockholder meeting date, in favor of the adoption of the Merger Agreement and the approval of the transactions contemplated thereby. The Voting Agreement will terminate in certain circumstances, including, among other circumstances, upon the occurrence of the Second Merger Effective Time, the termination of the Merger Agreement, the entry, without the Supporting Stockholder’s consent, into any amendment, waiver or modification to the Merger Agreement, or the Element Solutions Board changing its recommendation in favor of the adoption of the Merger Agreement.

Cautionary Statement Regarding Forward-Looking Statements

This Current Report on Form 8-K contains certain forward-looking statements within the meaning of the federal securities laws made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 with respect to the proposed transaction between Solstice and Element Solutions, that involve substantial risks and uncertainties. These statements can be identified by the fact that they do not relate strictly to historical or current facts, but rather are based on current expectations, estimates, assumptions and projections regarding, among other things, the anticipated benefits and timing of the proposed transaction, synergies, expected future financial position, total addressable market, position in specialty chemicals and advanced materials verticals and the industry, business and financial results of each company and the combined company, including the combined company’s expected Adjusted EBITDA and Adjusted EBITDA margin, expected synergies, net debt and net leverage, anticipated de-leveraging, expected accretion to Adjusted EPS and expected growth, margins and free cash flow. Forward-looking statements often include words such as “anticipates,” “estimates,” “expects,” “positioned,” “projects,” “forecasts,” “intends,” “plans,” “continues,” “could,” “believes,” “may,” “will,” “would,” “should,” “goals,” “pro forma” and words and terms of similar substance in connection with discussions of the proposed transaction and the future operating or financial performance of the combined company. As with any projection or forecast, forward-looking statements are inherently susceptible to uncertainty and changes in circumstances. Solstice’s, Element Solutions’ or the combined company’s actual results may vary materially from those expressed or implied in the forward-looking statements. Accordingly, undue reliance should not be placed on any forward-looking statement made by Solstice or on its behalf. Although Solstice and Element Solutions believe that the forward-looking statements contained in this communication are based on reasonable assumptions, you should be aware that a variety of factors, many of which are difficult to predict and outside of Solstice’s or Element Solutions’ control, could affect Solstice’s, Element Solutions’ or the combined company’s actual financial results or results of operations and could cause actual results to differ materially from those in such forward-looking statements, including, but not limited to: the completion of the proposed transaction on the anticipated terms and timing, including obtaining stockholder, regulatory and other approvals, anticipated tax treatment, unforeseen liabilities, future capital expenditures, revenues, expenses, earnings, synergies, economic performance, indebtedness, financial condition, future prospects, business and management strategies, expansion and growth of Solstice’s and Element Solutions’ businesses and other conditions to the completion of the proposed transaction; failure to realize the anticipated benefits of the proposed transaction, or that such benefits may take longer to realize or be more costly to achieve than expected, including as a result of delay in completing the proposed transaction, Solstice’s ability to integrate Element Solutions’ operations and product lines or due to unexpected costs, liabilities or delays; the ability of the parties to obtain or consummate financing related to the proposed transaction upon acceptable terms or at all; the dilution caused by Solstice’s issuance of additional shares of its common stock in connection with the consummation of the proposed transaction; the risk of a downgrade of the credit rating of Solstice’s indebtedness; a material adverse change in the financial condition of Solstice, Element Solutions or the combined company; potential litigation relating to the proposed transaction that could be instituted against Solstice, Element Solutions or their respective directors; Solstice’s and Element Solutions’ ability to implement their business strategies; the risk that disruptions from the proposed transaction will harm Solstice’s or Element Solutions’ respective businesses, including current plans and operations; the ability of Solstice or Element Solutions to retain and hire key personnel; potential adverse reactions or changes to business relationships resulting from the announcement or completion of the proposed transaction; uncertainty as to the long-term value of Solstice’s common stock; risks associated with third party contracts containing consent and/or other provisions triggered by the proposed transaction; legislative, regulatory, political and economic developments affecting Solstice’s, Element Solutions’ or the combined company’s respective businesses; the evolving legal, regulatory and tax regimes under which Solstice and Element Solutions operate; potential business uncertainty, including changes to existing business relationships, during the pendency of the proposed transaction that could affect Solstice’s and/or Element Solutions’ financial performance; restrictions during the pendency of the proposed transaction that may impact Solstice’s or Element Solutions’ ability to pursue certain business opportunities or strategic transactions; an overall decline in the health of the economy and the industries in which Solstice and Element Solutions operate, including as a result of inflation, tariffs and other trade barriers and restrictions, market volatility, geopolitical instability and social unrest, the possibility of an economic downturn or recession or other macroeconomic factors; unpredictability and severity of catastrophic events, including, but not limited to, acts of terrorism or outbreak of war or hostilities, as well as Solstice’s and Element Solutions’ response to any of the aforementioned factors; failure to receive the approval of the stockholders of Solstice and/or Element Solutions; and the occurrence of any event, change or other circumstance that could give rise to the termination of the Merger Agreement. The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties that affect the businesses of Solstice and Element Solutions described in the “Risk Factors” section of their respective Annual Reports on Form 10-K for the year ended December 31, 2025, Quarterly Reports on Form 10-Q and other documents filed by either of them from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those implied by forward-looking statements in this communication. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and Solstice and Element Solutions assume no obligation and do not intend to update or revise these forward-looking statements, whether as a result of new information, future events or otherwise, except as otherwise required by securities or other applicable law. Neither Solstice nor Element Solutions gives any assurance that either Solstice or Element Solutions will achieve its expectations.
