The Board also resolved to recommend that the Company’s stockholders vote to adopt the Merger Agreement.

The Merger

Pursuant to the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of common stock, par value $0.01 per share, of the Company (each, a “Common Share”) and each share of preferred stock, par value $0.01 per share designated as Series A Preferred Shares (the “Series A Preferred Shares”), in each case, issued and outstanding immediately prior to the Effective Time (other than shares owned by (i) Parent or Merger Sub or any of their respective Subsidiaries, (ii) the Company as treasury stock (each such share referred to in clauses (i) and (ii), an “Excluded Share” and, collectively, the “Excluded Shares”) and (iii) holders of Common Shares (“Dissenting Stockholders”) who have not voted in favor of the Merger or consented thereto and have properly exercised and perfected and not withdrawn, waived or lost a demand for appraisal rights pursuant to Section 262 of the Delaware General Corporation Law), will be converted into the right to receive:

•

with respect to each Common Share, $0.09 per Common Share in cash, without interest thereon (the “Common Stock Merger Consideration” and the aggregate of such amount for all Common Shares, the “Aggregate Merger Consideration”); and

•

with respect to each Series A Preferred Share, (1) an amount equal to the quotient of (x) the product of (a) the Aggregate Merger Consideration plus the aggregate consideration payable to the holders of Cash-Settled RSUs and Cash-Settled PSUs pursuant to the Merger Agreement, multiplied by (b) two (2), divided by (y) the total number of issued and outstanding Series A Preferred Shares as of immediately prior to the Effective Time, in cash, without interest thereon and (2) the number of fully paid and nonassessable units representing limited liability company interests of Parent to be issued by Parent such that immediately following such issuance and the Effective Time, the former holders of all Series A Preferred Shares shall hold, in the aggregate, 3.5% of Parent’s common equity (the “Preferred Stock Merger Consideration”, and together with the Common Stock Merger Consideration, the “Merger Consideration”).

Treatment of Equity Awards

At the Effective Time, each outstanding equity award will be treated as follows:

•

Each outstanding time-based restricted stock unit (a “Company Restricted Stock Unit”) that was granted under the Company’s 2018 Equity Incentive Plan (the “Company Stock Plan”) that is outstanding as of immediately prior to the Effective Time, whether vested or unvested, will become fully vested and will terminate and be automatically cancelled as of immediately prior to the Effective Time in exchange for the right to receive a lump sum cash payment of an amount equal to the product of (i) the number of Common Shares underlying such Company Restricted Stock Unit, multiplied by (ii) the Common Stock Merger Consideration.

•

Each outstanding performance-based restricted stock unit (a “Company Performance Stock Unit”) that was granted under the Company Stock Plan that is outstanding as of immediately prior to the Effective Time, whether vested or unvested, will become fully vested as if the applicable level of performance was achieved at target and will terminate and be automatically cancelled as of immediately prior to the Effective Time in exchange for the right to receive a lump sum cash payment of an amount equal to the product of (i) the number of Common Shares subject to such Company Performance Stock Unit that would vest based on the applicable target level of achievement of the performance metrics, multiplied by (ii) the Common Stock Merger Consideration.

Termination

The Merger Agreement contains certain customary termination rights for the Company and Parent, including (i) the right of the Company to terminate the Merger Agreement to enter into an Alternative Acquisition Agreement with respect to a Superior Proposal, subject to specified limitations and requirements, and (ii) the right of Parent to terminate the Merger Agreement if the Board changes its recommendation that the Company’s stockholders vote to adopt the Merger Agreement as described in the Merger Agreement. Subject to certain limitations, either party may terminate the Merger Agreement if the Merger is not consummated by November 22, 2025 (the “Termination Date”); provided, that, if as of the Termination Date all of the closing conditions, other than certain conditions related to obtaining consents and approvals from governmental entities, are satisfied or waived, or are capable of being satisfied at such time, the Termination Date shall automatically be extended until December 22, 2025 (or until January 22, 2026 if a subsequent extension is required to satisfy such conditions). In addition to the foregoing termination rights and certain other termination rights set forth in the Merger Agreement, Parent has the right to terminate the Merger Agreement if (a) the preliminary proxy statement has not been filed by the Company with the SEC on or prior to July 29, 2025, (b) the Company Requisite Vote has not been obtained by certain dates, (c) the RSA (as defined below) is terminated, (d) the Company commences or becomes subject to any chapter 11 bankruptcy proceedings, (e) either of the parties receive a request for additional information under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (f) any transaction litigation pending before a governmental entity is not resolved within certain timeframes, (g) any Voting and Support Agreement (as described below) is terminated, materially modified in a manner not approved by Parent, breached under certain circumstances or the Company waives any rights under a Voting and Support Agreement or (h) the Company has not received executed copies of certain contracts in form and substance reasonably acceptable to Parent within a certain timeframe.

The foregoing description of the Merger Agreement and the Merger does not purport to be complete, and is subject to and is qualified in its entirety by the terms and conditions of the Merger Agreement and any related agreements. The Merger Agreement contains representations, warranties and covenants that the respective parties made to each other as of the date of such agreement or other specific dates. The assertions embodied in those representations, warranties and covenants were made for purposes of the contract among the respective parties and are subject to important qualifications and limitations agreed to by the parties in connection with negotiating such agreement. The Merger Agreement will be provided to give investors information regarding its terms. It is not intended to provide any other factual information about the Company, Parent or any other party to the Merger Agreement or any related agreement. In particular, the representations, warranties, covenants and agreements contained in the Merger Agreement, which were made only for purposes of such agreement and as of specific dates, were for the benefit of the parties to the Merger Agreement, may be subject to limitations agreed upon by the contracting parties (including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the Merger Agreement instead of establishing these matters as facts) and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors and security holders. Investors and security holders are not third-party beneficiaries under the Merger Agreement and should not rely on the representations, warranties, covenants and agreements, or any descriptions thereof, as characterizations of the actual state of facts or condition of any party to the Merger Agreement. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures.

A copy of the Merger Agreement will be filed as an exhibit to an amendment of this Current Report on Form 8-K, and the foregoing description of the Merger Agreement is qualified in its entirety by reference thereto.

Voting and Support Agreements

Concurrently with the execution of the Merger Agreement on July 8, 2025, the Company entered into Voting and Support Agreements (the “Voting and Support Agreements”) with each of TPG Growth III Sidewall, L.P. (“TPG”) and certain directors, officers and other stockholders (collectively, the “Common Supporting Stockholders” and, together with TPG, the “Supporting Stockholders” and, individually, a “Supporting Stockholder”) with respect to shares owned of record or beneficially by each Supporting Stockholder (collectively, the “Owned Shares”).

The Supporting Stockholders have agreed to vote all of their Owned Shares:

•

in favor of the Merger, the adoption of the Merger Agreement, each of the other actions contemplated by the Merger Agreement or necessary or desirable in furtherance of the Merger and the other transactions contemplated by the Merger Agreement;

•

against any action or agreement that could reasonably be expected to result in any of the conditions to the consummation of the Merger under the Merger Agreement not being fulfilled or result in a breach of any covenant, representation or warranty or any other obligation or agreement of the Company contained in the Merger Agreement; and

•

against any Acquisition Proposal (which is not a Superior Proposal or an Acquisition Proposal for which the Board has made a Change in Recommendation) or any agreement, transaction or other matter that is intended to, or would reasonably be expected to, impede or interfere with the consummation of the Merger and the other transactions contemplated by the Merger Agreement.

In the event the Board makes a Change in Recommendation, each Supporting Stockholder may vote its shares with respect to the above matters in any manner it chooses.

Each Supporting Stockholder has agreed not to take certain actions, including (i) tendering any Owned Shares into any tender or exchange offer, (ii) transferring any Owned Shares (subject to certain exceptions), (iii) granting any proxies or powers of attorney or (iv) taking any action that would make any representation or warranty of such Supporting Stockholder contained in the Voting and Support Agreement untrue or incorrect in any material respect or have the effect of delaying, preventing or disabling such Supporting Stockholder from performing its obligations under the Voting and Support Agreement in any material respect.

In addition, TPG has agreed that the receipt of the aggregate amount of the Preferred Stock Merger Consideration pursuant to the terms of the Merger Agreement will constitute payment in full for all shares of Preferred Stock owned by TPG. TPG has agreed to waive (i) until the Effective Time or the termination of the Voting and Support Agreement, any and all rights to dividends it is entitled to receive as a holder of Series A Preferred Stock and (ii) any and all rights and remedies in connection with or related to the Merger (and any other transactions entered into by the Company in connection therewith, including the transactions contemplated by the Subscription Agreement (as described below)) other than rights and remedies arising under the Merger Agreement or related documents or transactions themselves, and/or the incurrence of indebtedness under the Company’s existing credit agreements it may have.

The Voting and Support Agreements will terminate upon the earliest to occur of (i) the Effective Time, (ii) the valid termination of the Merger Agreement in accordance with its terms and (iii) solely in the case of TPG, the occurrence of (a) a decrease in the Preferred Stock Merger Consideration, (b) the termination of the RSA with respect to the Company or the Consenting Lenders (as defined below) or (c) one or more chapter 11 bankruptcy proceedings are commenced by the Company or its subsidiaries or other parties commence chapter 11 bankruptcy proceedings regarding the Company or its subsidiaries and are not dismissed within 30 days.

The foregoing description of each Voting and Support Agreement does not purport to be complete and is subject to, and is qualified in its entirety by reference to each such Voting and Support Agreement, the forms of which will be filed as exhibits to an amendment of this Current Report on Form 8-K.

Subscription Agreement

Concurrently with the execution of the Merger Agreement on July 8, 2025, the Company entered into a Subscription Agreement (the “Subscription Agreement”) with Parent, pursuant to which Parent has agreed to purchase, and the Company has agreed to issue and sell to Parent, (i) 7,600,000 Common Shares (the “Subscription Shares”) or (ii) such other number of Common Shares as may be mutually agreed by the Company and Parent, in each case, for a purchase price of $0.09 per share.

The purchase of the Subscription Shares will take place one Business Day prior to the record date for the meeting of the Company’s stockholders to consider and vote on the adoption of the Merger Agreement. The Subscription Agreement contains representations, warranties, covenants and conditions to closing that are customary for an agreement of this nature.

In addition, if the Company enters into an Alternative Acquisition Agreement as permitted by the Merger Agreement, Parent has agreed to vote its Subscription Shares at any meeting of Company stockholders:

•

in favor of the transaction contemplated by such Alternative Acquisition Agreement (the “Alternative Acquisition”), and each of the other actions contemplated by the Alternative Acquisition Agreement or necessary or desirable in furtherance of the Alternative Acquisition and the other transactions contemplated by the Alternative Acquisition Agreement;

•

against any action or agreement that could reasonably be expected to result in any of the conditions to the consummation of the Alternative Acquisition under the Alternative Acquisition Agreement not being fulfilled or result in a breach of any covenant, representation or warranty or any other obligation or agreement of the Company contained in the Alternative Acquisition Agreement; and

•

against any proposal to enter into any other transaction, or any agreement, transaction or other matter that is intended to, or would reasonably be expected to, impede or interfere with the consummation of the Alternative Acquisition and the other transactions contemplated by the Alternative Acquisition Agreement.

In the event the Company engages in an Alternative Acquisition as permitted by the Merger Agreement, Parent will be entitled to receive at the closing of such Alternative Acquisition as consideration for the Subscription Shares to be paid in connection with such Alternative Acquisition, an amount that is equal to the purchase price that Parent paid to acquire the Subscription Shares.

The Subscription Shares being sold to Parent pursuant to the Subscription Agreement are exempt from registration pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”).

The foregoing description of the Subscription Agreement does not purport to be complete and is subject to, and is qualified in its entirety by reference to the Subscription Agreement, a copy of which will be filed as an exhibit to an amendment of this Current Report on Form 8-K.

Recapitalization Support Agreement

Concurrently with the execution of the Merger Agreement on July 8, 2025, the Company and each of its subsidiaries (together with the Company, the “Company Group”) entered into a Recapitalization Support Agreement (the “RSA”) with the lenders holding 100% of the term loan debt under the Existing Term Loan Credit Agreement (the “Consenting Term Loan Lenders” and, collectively, with any other party that executes a joinder to the RSA that subsequently becomes effective, the “Consenting Parties”).

Pursuant to the RSA, the Consenting Parties have agreed to support a transaction (the “Transaction”) involving (i) the partial equitization of the term loans under the Existing Term Loan Credit Agreement and (ii) a recapitalization of the Company, subject to the terms and conditions of the RSA and the recapitalization term sheet attached thereto as Exhibit A (the “Term Sheet”).

The RSA provides that the Transaction will be implemented on either (i) a consensual out-of-court basis (the “Out-of-Court Structure”), without recourse to proceedings under chapter 11 of title 11 of the United States Code (the “Bankruptcy Code”) or (ii) an in-court basis (the “Chapter 11 Structure”) through prepackaged or prearranged cases for the Company and certain other of its subsidiaries, if any (collectively, the “Debtors”), under chapter 11 of the Bankruptcy Code (the “Chapter 11 Cases”).

The Term Sheet contemplates, among other things:

•

The Transaction will be implemented either (i) through the Out-of-Court Structure through the Merger Agreement or (ii) through the Chapter 11 Structure if the following milestones are not met:

•

(y) the Company fails to file the preliminary proxy statement on or prior to July 29, 2025; or

•

(z) the Merger is not approved by the required vote at a duly called meeting of the stockholders of the Company (or any adjournment or postponement thereof) prior to:

•

October 1, 2025, if the SEC informs the Company that it will not review the proxy statement; or

•

October 31, 2025, if the SEC informs the Company that it will review the proxy statement and issues any comments in such review.

•

Each Consenting Term Loan Lender will consent to:

•

the conversion, on a dollar-for-dollar basis, to Take Back Term Loans (as defined in the Term Sheet) of an amount of its Existing Term Loan Claims (as defined in the Term Sheet) that will result in (x) the aggregate principal amount of funded debt, preferred equity or other securities entitled to recover before the New Common Equity (as defined in the Term Sheet), in each case, of Reorganized Superior (as defined in the Term Sheet), and its subsidiaries immediately following the Effective Time less (y) the aggregate amount of unrestricted cash and cash equivalents of Reorganized Superior, and its subsidiaries immediately following the Effective Time, not exceeding $125,000,000; and

•

if the Transaction is implemented through the Out-of-Court Structure, the contribution of the balance of its Existing Term Loan Claims to New TopCo in exchange for 100% of the New Common Equity, subject to dilution by the Out-of-Court Preferred Shareholder Equity Distribution and the MIP (each as defined in the Term Sheet); or

•

if the Transaction is implemented pursuant to the Chapter 11 Structure, as part of the chapter 11 plan, the full satisfaction and extinguishment of the balance of its claims in exchange for 100% of the New Common Equity, subject to dilution by the In-Court Preferred Shareholder Equity Distribution (as defined in the Term Sheet), if applicable, and the MIP.

•

The Series A Preferred Shares will be cancelled, released, and extinguished, and TPG will receive:

•

if the Transaction is implemented through the Out-of-Court Structure, the Preferred Stock Merger Consideration; or

•

if the Transaction is implemented through Chapter 11 Cases, either:

•

if (A) TPG votes to accept the chapter 11 plan and (B) all classes of creditors senior to TPG vote to accept, or are deemed to accept, the chapter 11 plan, 1.75% of the New Common Equity, subject to dilution by the MIP (as defined in the Term Sheet); or

•

if (X) TPG votes to reject the chapter 11 plan or (Y) any class of creditors votes to reject, or is deemed to reject, the chapter 11 plan, no distribution or consideration.

•

The existing Common Shares will be cancelled, released, and extinguished, and each holder of Common Shares will receive:

•

if the Transaction is implemented through the Out-of-Court Structure, the Common Stock Merger Consideration; or

•

if the Transaction is implemented through the Chapter 11 Structure, no distribution or consideration.

•

The Company shall, at the option of the Requisite Consenting Term Loan Lenders (as defined in the RSA), (a) execute an amendment to the Existing Revolving Credit Agreement (as defined in the RSA) in form and substance reasonably acceptable to the Requisite

Consenting Term Loan Lenders that results in the Existing Revolving Credit Facility (as defined in the RSA) remaining outstanding upon and after the Effective Time on terms not materially less favorable to the Company than the Existing Revolving Credit Facility or otherwise reasonably acceptable to the Requisite Consenting Term Loan Lenders, including with respect to any waivers and/or consents (including in respect of a change of control) necessary to effectuate the Transaction or (b) refinance the Existing Revolving Credit Facility with a new super-priority revolving credit facility of a similar size and on terms not materially less favorable to the Company than the Existing Revolving Credit Facility or otherwise reasonably acceptable to the Requisite Consenting Term Loan Lenders.

•

If the Transaction is implemented through the Out-of-Court Structure, (i) all other claims against the Company Group will be satisfied in the ordinary course of business or otherwise be unimpaired and (ii) pursuant to the Subscription Agreement (as described above), the Company shall issue 7,600,000 Common Shares (or such other number of Common Shares as may be mutually agreed by the Company and Parent) to Parent at the same price per share in cash as the Common Merger Consideration.

The RSA also contemplates the following milestones with respect to a Transaction implemented through a Chapter 11 Structure:

•

in the event of prepackaged Chapter 11 Cases, no later than seven Business Days (as defined in the RSA) prior to the Petition Date (as defined in the RSA), the Company shall commence the Solicitation (as defined in the RSA);

•

in the event of prepackaged Chapter 11 Cases, no later than two Business Days prior to the Petition Date, the Company shall complete the Solicitation;

•

no later than the Commencement Deadline (as defined in the RSA), the Petition Date shall have occurred.

•

in the event of prepackaged or prearranged Chapter 11 Cases, no later than one day after the Petition Date, the Debtors shall have filed the Plan, Disclosure Statement, and motion seeking approval of the DIP Financing, (each as defined in the RSA), if applicable;

•

no later than five days after the Petition Date, the Bankruptcy Court (as defined in the RSA) shall have entered an interim DIP Order (as defined in the RSA), if applicable;

•

no later than 30 days after the Petition Date, the Bankruptcy Court shall have entered a final DIP Order, if applicable; and

•

(1) in the event of prepackaged Chapter 11 Cases, no later than 60 days after the Petition Date, the Bankruptcy Court shall have entered the Confirmation Order (as defined in the RSA) the Disclosure Statement Order (as defined in the RSA), or (2) in the event of prearranged Chapter 11 Cases, no later than 60 days after the Petition Date, the Bankruptcy Court shall have entered the Disclosure Statement Order and no later than 120 days after the Petition Date, the Bankruptcy shall have entered the Confirmation Order.

The RSA contains certain covenants on the part of each of the Consenting Parties, including, among other things, (i) commitments to support, and to use commercially reasonable efforts and timely take all reasonable actions necessary to support, implement and consummate the Transaction and (ii) commitments to negotiate in good faith and use commercially reasonable efforts to execute and implement definitive documents that are consistent with the RSA.

Pursuant to the RSA, the Consenting Parties have agreed to implement the Transaction by no later than 120 calendar days after the Petition Date in the event of prepackaged Chapter 11 Cases or 150 calendar days after the Petition Date in the event of prearranged Chapter 11 Cases, in each case, if the Effective Time has not occurred, which deadlines may be extended or waived in writing by the Requisite Consenting Term Loan Lenders in their sole discretion.

Forward Looking-Statements

This Current Report on Form 8-K contains statements that are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include all statements that do not relate solely to historical or current facts and can generally be identified by the use of future dates or words such as “assumes,” “may,” “should,” “could,” “will,” “expects,” “expected,” “seeks to,” “anticipates,” “plans,” “believes,” “estimates,” “foresee,” “intends,” “guidance,” “predicts,” “projects,” “projecting,” “potential,” “targeting,” “will likely result,” or “continue,” or the negative of such terms and other comparable terminology. These forward-looking statements involve a number of risks and uncertainties, some of which are beyond Superior’s control, including, without limitation, future fluctuations in the Company’s market capitalization and stockholders’ equity; and the expected timing and process for listing on the Pink Open Market. Therefore, actual outcomes and results may differ materially from what is expressed or forecasted in such forward-looking statements due to numerous factors, risks, and uncertainties discussed in Superior’s SEC filings and reports.

New risks and uncertainties arise from time to time, and it is impossible for us to predict these events or how they may affect Superior. The Company disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events and/or otherwise, except as may be required by law.

2Cautionary Statement Regarding Forward-Looking Statements

This current report on Form 8-K contains “forward-looking statements” within the meaning of the federal securities laws, including Section 27A of the Securities Act and Section 21E of the Exchange Act. In this context, forward-looking statements often address future business and financial events, conditions, expectations, plans or ambitions, and often include, but are not limited to, words such as “believe,” “expect,” “may,” “will,” “should,” “could,” “would,” “anticipate,” “estimate,” “intend,” “plan,” “seek,” “see,” “target” or similar expressions, or variations or negatives of these words, but not all forward-looking statements include such words. Forward-looking statements by their nature address matters that are, to different degrees, uncertain, such as statements about the consummation of the proposed transactions contemplated by the Merger Agreement, the RSA and the related documents (the “Proposed Transactions”), including the expected time period to consummate the Proposed Transactions, and the anticipated benefits thereof. All such forward-looking statements are based upon current plans, estimates, expectations and ambitions that are subject to risks, uncertainties and assumptions, many of which are beyond the control of the Company and Parent, that could cause actual results to differ materially from those expressed in such forward-looking statements. Important risk factors that may cause such a difference include, but are not limited to: the substantial doubt regarding the Company’s ability to continue as a going concern; the consummation of the Proposed Transactions on the anticipated terms and timing, or at all, including obtaining regulatory approvals and receipt of the approval of the Company’s stockholders; the achievement of the milestones set forth in the RSA by their respective deadlines or at all; the occurrence of any event, change or other circumstance that could give rise to the termination of the definitive transaction agreements; the anticipated tax treatment of the Proposed Transactions; the possibility that any of the anticipated benefits of the Proposed Transactions will not be realized or will not be realized within the expected time period; potential litigation relating to the

Proposed Transactions; the risk that disruptions from the Proposed Transactions will harm the Company’s business, including current plans and operations and that management’s time and attention will be diverted on transaction-related issues; potential adverse reactions or changes to business relationships, including with employees, suppliers, customers, competitors or credit rating agencies, resulting from the announcement or completion of the Proposed Transactions; the potential for modification or adjustment of the Merger Agreement or the RSA; the parties’ ability to satisfy their respective conditions and consummate the Proposed Transactions; certain restrictions during the pendency of the Proposed Transactions that may impact the Company’s financial performance, operating results, ability to pursue certain business opportunities or strategic transactions or otherwise operate its business; fees, costs and expenses and the possibility that the Proposed Transactions may be more expensive to complete than anticipated, including as a result of unexpected factors or events; the events of industry, market, economic, political or regulatory conditions outside of the Company’s control; future fluctuations in the Company’s market capitalization and stockholders’ equity; the expected timing and process for the delisting of the Common Shares from the NYSE and deregistration under the Securities Act; other risks related to the Proposed Transactions that will be included in the proxy statement on Schedule 14A filed with the SEC in connection with the Merger (the “Proxy Statement”); and those risks described in Item 1A of Part I of the Company’s Annual Report on Form 10-K, filed with the SEC on March 6, 2025, in Item 1A of Part II of the Company’s Quarterly Report on Form 10-Q, filed with the SEC on May 12, 2025, and the Company’s other filings with the SEC. These disclosures are incorporated by reference in this communication. While the list of factors presented here is considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Readers are cautioned not to place undue reliance on this forward-looking information, which is as of the date of this communication. The Company does not intend to update these statements unless required by the securities or other applicable laws to do so, and the Company undertakes no obligation to publicly release the result of any revisions to any such forward-looking statements that may be made to reflect events or circumstances after the date of this communication.
