STIPULATION AND AGREEMENT OF SETTLEMENT

This Stipulation and Agreement of Settlement dated October 24, 2025 (the “Stipulation”) is made and entered into by and among the following parties, by and through their respective counsel: (1) plaintiffs in the above-captioned stockholder derivative actions (the “Actions”) pending in the United States District Court for the District of Kansas (the “Court”), Fabrizio Morelli (“Morelli”) and George Assad (“Assad”) (the “Plaintiffs”); (2) individual defendants Kevin S. Crutchfield, Edward C. Dowling, Jr., Lorin Crenshaw, Jennifer (Jenny) Hood, Richard

P. Dealy, Jonathan (Jon) Chisholm, Jill Gardiner, Gareth Joyce, Melissa M. Miller, Joseph E. Reece, Lori A. Walker, James Standen, and Shane Wagnon (collectively, the “Individual Defendants”); and (3) nominal defendant Compass Minerals International, Inc. (“Compass” or the “Company,” and together with the Individual Defendants, “Defendants”) (the “Parties” refers collectively to Plaintiffs and Defendants).

This Stipulation, subject to the approval of the Court, is intended to fully, finally, and forever resolve, discharge, and settle any and all Released Claims (as defined herein) upon the terms and subject to the conditions set forth herein.

I.FACTUAL AND PROCEDURAL BACKGROUND

Plaintiffs allege that, inter alia, between February 8, 2023, and March 25, 2024, the Individual Defendants breached their fiduciary duties by issuing and/or causing the Company to issue false and misleading statements and omissions and failing to disclose and/or causing the Company to fail to disclose to the investing public, among other things, that testing on the Company’s proprietary magnesium chloride-based aerial fire retardants did not confirm such fire retardants’ safety, thus overstating the prospects of the U.S. Forest Service awarding Compass a renewed contract for using such fire retardants for the 2024 fire season.

2

A.The Actions

On October 30, 2024, plaintiff Morelli filed a Verified Shareholder Derivative Complaint on behalf of Compass in the Court against certain of the Individual Defendants alleging claims for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, waste of corporate assets, and for violations of Section 14(a) of the Exchange Act, and against certain of the Individual Defendants for contribution under Sections 10(b) and 21D of the Exchange Act, captioned Morelli v. Crutchfield, et al., Case No. 2:24-cv-02496-DDC-BGS (the “Morelli Action”) (Morelli Action, ECF No. 1).

On December 5, 2024, the parties in the Morelli Action filed a stipulation and joint motion to stay the Morelli Action until: (i) the Securities Class Action (defined herein) was dismissed with prejudice; or (ii) the motion to dismiss in the Securities Class Action was denied in whole or in part. (Morelli Action, ECF No. 13), which the Court so-ordered on December 17, 2024. (Morelli Action, ECF No. 18).

On April 9, 2025, plaintiff Assad filed a Verified Shareholder Derivative Complaint on behalf of Compass in the Court against certain of the Individual Defendants alleging claims for breach of fiduciary duty and violations of Section 14(a) of the Exchange Act, captioned Assad v. Crutchfield, et al., Case No. 2:25-cv-02186-DDC-ADM (the “Assad Action”). (Assad Action, ECF No. 1).

On May 30, 2025, the Parties filed a joint motion to consolidate the Morelli Action and Assad Action, appoint co-lead counsel for Plaintiffs, and set a briefing schedule for the Actions (Morelli Action, ECF No. 23, Assad Action, ECF No. 19).

On June 3, 2025, the Court consolidated the Morelli Action and Assad Action for purposes of discovery and ordered, inter alia, that Plaintiffs “shall file a consolidated complaint by June 30, 2025” and that Defendants “shall answer, move to dismiss, or otherwise respond to”

3

such consolidated complaint by July 28, 2025. (Morelli Action, ECF No. 24, Assad Action, ECF No. 26).

On June 24, 2025, the Parties filed a joint motion for extension of time, requesting that the Court extend the deadlines for Plaintiffs to file their consolidated complaint and for Defendants to respond to such complaint by sixty days in light of the Parties’ ongoing efforts to resolve the Actions. (Morelli Action, ECF No. 27).

On June 25, 2025, the Court ordered Plaintiffs to file a consolidated complaint by July 30, 2025, and Defendants to respond to such consolidated complaint by August 29, 2025. (Morelli Action, ECF No. 28).

On July 30, 2025, Plaintiffs filed their Verified Amended Consolidated Shareholder Derivative Complaint against the Individual Defendants in both Actions. (Morelli Action, ECF No. 29, Assad Action, ECF No. 28).

On August 11, 2025, the Parties filed a joint motion (the “Joint Motion”) to stay the Actions pending the submission of a formal settlement agreement and motion for preliminary approval, which documents the Parties represented they would submit to the Court in “approximately sixty (60) days.” (Morelli Action, ECF No. 30).

On August 12, 2025, the Court granted the Joint Motion, staying all deadlines in the Actions until October 10, 2025, and further ordering that “[i]f the parties have not filed a settlement agreement by October 10, 2025, they are directed to either file a joint motion seeking extension of the stay or a joint status report that includes a proposed revised schedule of deadlines.” (Morelli Action, ECF No. 31).

4

On October 8, 2025, the Court granted a joint motion seeking a 14-day extension of the stay, thereby extending the deadline to file a settlement agreement or a joint status report until October 24, 2025. (Morelli Action, ECF. No. 33).

B.The Securities Class Action

On April 24, 2024, plaintiff John Valentine filed a securities class action in the Court against the Company and defendants Kevin S. Crutchfield, Edward C. Dowling, Jr., Lorin Crenshaw, and Jennifer Hood for violations of the Securities Exchange Act of 1934 (the “Exchange Act”), alleging substantially the same false and misleading statements that are alleged in the Actions, captioned Valentine v. Compass Minerals International, Inc., et al., Case No. 2:24-cv-02165-EFM-ADM (the “Securities Class Action”).

On February 10, 2025, plaintiffs in the Securities Class Action filed an amended complaint, which, inter alia, named James Standen as an additional defendant (Securities Class Action, ECF No. 24).

On June 30, 2025, the parties to the Securities Class Action filed an Unopposed Motion for Preliminary Approval of Class Action Settlement. (Securities Class Action, ECF No. 32). On July 25, 2025, the Court preliminarily approved the settlement in the Securities Class Action. (Securities Class Action, ECF No. 35). A hearing on the Unopposed Motion for Preliminary Approval of Class Action Settlement is scheduled on November 18, 2025. (Securities Class Action, ECF No. 37).

C.Settlement Negotiations

On May 20, 2025, Plaintiffs sent a settlement demand letter to Defendants that, inter alia, proposed a settlement framework that included corporate governance reforms to be implemented by Compass that were designed to address what Plaintiffs allege were the governance deficiencies that resulted in the wrongdoing alleged in the Actions. On July 21, 2025, following

5

the exchange of numerous settlement proposals and counterproposals during the prior two months, the Parties reached an agreement in principle on the material terms of a settlement of the Actions, including the agreed to governance reforms (the “Reforms”), subject to Court approval.

Following the Parties’ agreement in principle on the material terms of the settlement, the Parties agreed to participate in a virtual mediation (the “Mediation”) on September 12, 2025, with a highly respected and nationally known mediator, Michelle Yoshida, Esq. of Phillips ADR (the “Mediator”), to negotiate the attorneys’ fees and expenses that would be payable by Compass’s insurers to Plaintiffs’ Counsel in recognition of the substantial benefits achieved through the settlement.

On September 5, 2025, the Parties exchanged with each other and submitted to the Mediator their respective mediation statements.

On September 12, 2025, the Parties attended the Mediation. At the end of the Mediation, the Parties accepted a double-blind proposal made by the Mediator for Compass’s insurers to pay

$850,000.00 in attorneys’ fees and expenses to Plaintiffs’ Counsel, subject to Court approval.

II.PLAINTIFFS’ CLAIMS AND THE BENEFITS OF SETTLEMENT

Plaintiffs believe that the derivative claims in the Actions have substantial merit and Plaintiffs’ entry into this Stipulation is not intended to be and shall not be construed as an admission or concession concerning the relative strength or merit of the claims alleged in the Actions. However, Plaintiffs and Plaintiffs’ Counsel recognize and acknowledge the significant risk, expense, and length of continued proceedings necessary to prosecute the derivative claims against the Individual Defendants through trial and possible appeals. Plaintiffs’ Counsel also have taken into account the uncertain outcome and the risk of any litigation, especially in complex cases such as the Actions, as well as the difficulties and delays inherent in such litigation. Plaintiffs’ Counsel are also mindful of the inherent problems of establishing standing in derivative litigation and the possible defenses to the claims alleged in the Actions.

6

Plaintiffs’ Counsel have conducted extensive investigation and analysis, including, inter alia: (i) reviewing and analyzing Compass press releases, public statements, and filings with the

U.S. Securities and Exchange Commission (“SEC”); (ii) reviewing and analyzing securities analysts’ reports and advisories and media reports about the Company; (iii) reviewing and analyzing the pleadings and orders in the Securities Class Action; (iv) researching the applicable law with respect to the claims alleged and the potential defenses thereto; (v) preparing and filing initial complaints and an amended complaint in the Actions; (vi) researching and evaluating factual and legal issues relevant to the claims; (vii) engaging in settlement negotiations with Defendants’ counsel regarding the specific facts, and perceived strengths and weaknesses of the Actions, and other issues in an effort to facilitate negotiations; (viii) researching the Company’s corporate governance structure in connection with settlement efforts; (ix) preparing a comprehensive written settlement demand and modified demands over the course of the Parties’ settlement negotiations; and (x) negotiating and drafting this Stipulation.

Based on Plaintiffs’ Counsel’s thorough review and analysis of the relevant facts, allegations, defenses, and controlling legal principles, Plaintiffs’ Counsel believe that the Settlement set forth in this Stipulation is fair, reasonable, and adequate, and confers substantial benefits upon Compass. Based upon Plaintiffs’ Counsel’s evaluation, Plaintiffs have determined that the Settlement is in the best interests of Compass and its stockholders and have agreed to settle the Actions upon the terms and subject to the conditions set forth herein.

7

III.INDIVIDUAL DEFENDANTS’ DENIALS OF WRONGDOING AND LIABILITY

Throughout the Actions, the Individual Defendants have denied, and continue to deny, any and all of the claims alleged in the Actions, including any allegations of wrongdoing, fault, negligence, liability, or damage to the Plaintiffs, the Company, or the Company’s stockholders. Specifically, the Individual Defendants expressly have denied, and continue to deny, that they engaged in any wrongdoing or violation of the law; that they breached any fiduciary duty, including the duty of care or duty of loyalty; that they wasted corporate assets, were unjustly enriched, engaged in gross mismanagement; that the Company’s disclosures were deficient in any way; that they violated any securities laws; and that they acted in bad faith or improperly in any way. The Individual Defendants assert that, at all relevant times, they acted in good faith and in a manner they reasonably believed to be in the best interests of Compass and its shareholders. The Individual Defendants maintain that they have meritorious defenses to all claims alleged in the Actions.

Nonetheless, taking into account the uncertainty and risks inherent in any litigation, especially in complex cases such as the Actions, Defendants have concluded that further litigation of the Actions could be protracted, burdensome, and expensive, and that it is desirable and beneficial that the claims asserted in, or that could be asserted in, the Actions be fully and finally settled and terminated in the manner and upon the terms and conditions set forth in this Stipulation. Nothing in this Stipulation shall be construed as any admission or concession by the Individual Defendants of any wrongdoing, fault, negligence, liability, or damages whatsoever. Neither the Settlement nor any of the terms of this Stipulation shall be construed or deemed to be evidence of or constitute an admission, concession, or finding with respect to any claim or

8

allegation of any fault, negligence, liability, wrongdoing, or damage whatsoever, or any infirmity in the defenses that the Defendants have, or could have, asserted.

16

Compass shall be solely responsible for paying the costs and expenses related to providing notice of the Settlement set forth in this paragraph or as otherwise required by the Court. The Parties believe the form and manner of the notice procedures set forth in this paragraph constitute adequate and reasonable notice to Compass stockholders pursuant to applicable law and due process.

4.ATTORNEYS’ FEES AND REIMBURSEMENT OF EXPENSES

4.1 In consideration of the substantial benefits conferred upon Compass by the Reforms as a direct result of Plaintiffs’ and Plaintiffs’ Counsel’s efforts in connection with the Actions, and subject to Court approval, the Company’s insurers shall pay to Plaintiffs’ Counsel, collectively, their attorneys’ fees and costs in the amount of eight hundred fifty thousand dollars ($850,000.00) (the “Fee and Expense Amount”).

4.2 The Fee and Expense Amount shall be paid to The Brown Law Firm, P.C.’s escrow account (the “Escrow Account”) within twenty (20) days after the later of (i) the date of entry of the Preliminary Approval Order, or (ii) the date on which Plaintiffs’ Counsel provides written payment instructions and a W-9 form to Defendants’ Counsel, and which amount, to the extent approved by the Court, shall be released from the Escrow Account once the Court enters the

17

Judgment and an order approving the Fee and Expense Amount—notwithstanding the existence of any collateral attacks on the Settlement, including, without limitation, any objections or appeals—to the firms comprising Plaintiffs’ Counsel. Plaintiffs’ Counsel shall allocate the Fee and Expense Amount as agreed among themselves. Defendants are not responsible for the allocation of the Fee and Expense Amount among Plaintiffs’ Counsel. Plaintiffs’ Counsel shall make no request to the Court for (and hereby release any right they may otherwise have to seek) attorneys’ fees and/or costs beyond the Fee and Expense Amount. Approval of this Stipulation and entry of Judgment thereon pursuant to Federal Rule of Civil Procedure 54(b) is not conditioned on and need not await any ruling by the Court pertaining solely to the Fee and Expense Amount; and any appeal or proceeding seeking subsequent judicial review pertaining solely to the Fee and Expense Amount shall not in any way delay or affect the Judgment from becoming Final or otherwise preclude the Judgment from becoming Final.

4.3 In the event that the Judgment fails to become Final as defined in section IV, paragraph 1.11, if a collateral attack is successful or the Settlement is otherwise terminated, or to the extent that the Court does not approve Plaintiffs’ Counsel’s application for an award of attorneys’ fees and costs in the full amount of the Fee and Expense Amount, Plaintiffs’ Counsel must refund the Fee and Expense Amount to the extent it is denied or reduced to Compass’s insurers within thirty (30) days from receiving notice from Defendants’ Counsel or from a court of appropriate jurisdiction.

4.4 Plaintiffs’ Counsel may apply to the Court for service awards of up to one thousand five hundred dollars ($1,500.00) for each of the two Plaintiffs to be paid from the Fee and Expense Amount in recognition of Plaintiffs’ participation and effort in the prosecution of the Actions (the “Service Awards”). Defendants shall not object to the application for the Service Awards.

18

Approval of this Stipulation and entry of Judgment thereon pursuant to Federal Rule of Civil Procedure 54(b) is not conditioned on and need not await any ruling by the Court pertaining solely to the Service Award; and any appeal or proceeding seeking subsequent judicial review pertaining solely to the Service Award shall not in any way delay or affect the Judgment from becoming Final or otherwise preclude the Judgment from becoming Final.

4.5 Any order or proceeding (or any portion thereof) relating to the Fee and Expense Amount or the Service Award, or any appeal from any order (or any portion thereof) relating thereto or reversal or modification thereof, shall have no effect on the Settlement and shall not operate to terminate or cancel this Stipulation or to affect or delay the finality of the Judgment approving this Stipulation. Except as provided in the Stipulation, Defendants shall bear no other expenses, costs, damages or fees incurred by the Plaintiffs, Plaintiffs’ Counsel, or any of their attorneys, experts, advisers, agents or representatives. Defendants and Defendants’ Counsel shall have no responsibility for or liability with respect to the allocation among any counsel for any Plaintiffs of the Fee and Expense Amount as approved by the Court, and Defendants take no position with respect to such matters. The Fee and Expense Amount represents the entirety of Defendants’ or their insurers’ financial obligations under this Stipulation and in connection with this Settlement.

4.6 For the avoidance of doubt, no order of the Court or modification or reversal on appeal of any order of the Court concerning the Fee and Expense Amount or Service Award shall operate to terminate or cancel this Stipulation, constitute grounds for cancellation or termination of the Stipulation.

19

Summary

On October 24, 2025, Compass, in its capacity as a nominal defendant, entered into the Stipulation to resolve the Actions, which Stipulation was filed in the Court. The Actions were brought derivatively on behalf of Compass against certain current and former directors and officers of the Company. Compass was named as a nominal defendant in the Actions. The Stipulation, and the settlement contemplated therein (the “Settlement”), subject to the approval of the Court, are intended by the Parties to fully, finally, and forever compromise, resolve, discharge, and settle the Released Claims and to result in the complete dismissal of the Actions with prejudice, upon the terms and subject to the conditions set forth in the Stipulation. The proposed Settlement requires the Company to adopt and maintain certain corporate governance reforms and procedures, as outlined in Exhibit A to the Stipulation (the “Reforms”), subject to Court approval.

In recognition of the substantial benefits conferred upon Compass as a direct result of the Reforms achieved through the prosecution and Settlement of the Actions, the Parties agreed on September 12, 2025, that Compass’s insurers shall pay to Plaintiffs’ Counsel attorneys’ fees and expenses in the amount of eight hundred fifty thousand dollars ($850,000.00) (the “Fee and Expense Amount”), subject to Court approval. Plaintiffs’ Counsel shall also apply to the Court for service awards to be paid to the two Plaintiffs in an amount of up to one thousand five hundred dollars ($1,500.00) each (the “Service Awards”), to be paid out of the Fee and Expense Amount.

This notice is a summary only and does not describe all of the details of the Stipulation and its exhibits. For full details of the matters discussed in this summary, please see the full Stipulation and its exhibits posted on the Investor Relations portion of the Company’s website, www., contact Plaintiffs’ Counsel as set forth below, or inspect the full Stipulation and its exhibits filed with the Clerk of the Court.

What are the Lawsuits About?

The Actions are brought derivatively on behalf of nominal defendant Compass and allege that, inter alia, between February 8, 2023, and March 25, 2024, at least, the Individual Defendants breached their fiduciary duties by issuing and/or causing Compass to issue false and misleading statements and omissions and failing to disclose and/or causing the Company to fail to disclose to the investing public, among other things, that testing on the Company’s proprietary magnesium chloride-based aerial fire retardants did not confirm such fire retardants’ safety and, thus, overstating the prospects of the U.S. Forest Service awarding Compass a renewed contract for using its proprietary magnesium chloride-based aerial fire retardants for the 2024 fire season.

Why is there a Settlement of the Actions?

The Court has not decided in favor of Defendants or the Plaintiffs. Instead, the Parties agreed to the Settlement to avoid the distraction, costs, and risks of further litigation, and because the Parties agree, and the Company determined, that the Reforms that the Company will adopt, implement, and maintain as part of the Settlement provide substantial benefits to Compass and its stockholders.

Individual Defendants have denied and continue to deny each and all of the claims and contentions alleged by the Plaintiffs in the Actions. Individual Defendants have expressly denied and continue to deny all charges of wrongdoing or liability against them arising out of any of the conduct, statements, acts, or omissions alleged, or that could have been alleged, in the Actions. Nonetheless, Defendants have concluded that it is desirable for the Actions to be fully and finally settled in the matter and upon the terms and conditions set forth in this Stipulation.

The Settlement Hearing, and Your Right to Object to the Settlement

The Court entered an order preliminarily approving the Stipulation and the Settlement contemplated therein (the “Preliminary Approval Order”) and providing for notice of the Settlement to be provided to current Compass stockholders who owned Compass stock as of October 24, 2025 (“Current Compass Stockholders”).
