BACKGROUND OF THE LITIGATION 3 The parties understand and agree that the entity described in this litigation as “Banco Nacional de México, S.A., Institución de Banca Múltiple, Grupo Financiero Banamex” refers to Banco Nacional de Mexico, S.A., integrante del Grupo Financiero Banamex. 4 Deutsche Bank Mexico came under the ownership of Grupo Financiero Citi México, S.A. de C.V. and Citi GSCP Inc., both of which are indirect, wholly owned subsidiaries of Citigroup Inc. Deutsche Bank Mexico was renamed Banco Citi México, S.A. Institución de Banca Múltiple, Grupo Financiero Citi México, which is now an indirect, wholly owned subsidiary of Citigroup Inc. 5 Capitalized terms, not otherwise defined herein, shall have the same meanings assigned to them in the Settlement Agreement, as applicable. QUESTIONS? CALL 1-877-829-2941 OR VISIT WWW.MGBANTITRUSTSETTLEMENT.COM PAGE 2 OF 9 A. The Nature of the Litigation Plaintiffs allege that each Defendant,6 from January 1, 2006 through April 19, 2017, inclusive, conspired to fix the prices for Mexican Government Bonds issued by the Mexican government through the Bank of Mexico (“Banxico”). Plaintiffs allege that each Defendant transacted in price-fixed MGBs at artificial prices with market participants like Plaintiffs and the Class. Plaintiffs’ lawsuit contends that Defendants fixed MGB prices through several interrelated means. First, Defendants allegedly sold newly issued MGBs purchased at auction into the secondary market at artificially high, price- fixed terms. Plaintiffs allege that Defendants controlled a significant market share of MGBs through privileges associated with their market maker status. Defendants allegedly manipulated the MGB market by communicating prices, pooling information about expected customer flows, and exchanging other confidential bank information through interbank chatrooms, telephone calls, and in-person meetings. Plaintiffs claim that Defendants’ conspiracy caused Plaintiffs and the Class to pay higher prices for newly issued MGBs sold into the secondary market than they otherwise would have. Second, Defendants allegedly agreed to fix the “bid-ask spread” artificially wider when offering to buy or sell MGBs in secondary market trading with Plaintiffs and the Class. Plaintiffs allege that Defendants fixed bid-ask spreads by communicating prices, expected customer flows, and sensitive bank information through interbank chatrooms, telephone calls, and in-person meetings. Plaintiffs claim that the result of Defendants’ alleged conspiracy was that investors were underpaid by Defendants’ suppression of the “bid price,” the price at which Defendants offered to buy MGBs from investors, and overcharged by Defendants’ inflation of the “ask price,” the price at which Defendants offered to sell MGBs to investors. Plaintiffs have asserted legal claims under federal antitrust law and common law. Plaintiffs and Plaintiffs’ Lead Counsel believe that Settlement Class Members have been damaged by Defendants’ alleged conduct. Settling Defendants do not agree with the allegations made by Plaintiffs, believe that they have meritorious defenses to Plaintiffs’ allegations, and believe that Plaintiffs’ claims would have been rejected prior to trial, at trial (had Plaintiffs successfully certified a class and survived summary judgment motions), or on appeal. As a result, Settling Defendants believe Settlement Class Members would have received nothing if the litigation had continued to trial. The Court has not decided in favor of Plaintiffs or the Settling Defendants. Instead, Plaintiffs’ Lead Counsel engaged in negotiations with Settling Defendants to reach a negotiated resolution of the claims against Settling Defendants in this Action. The Settlement allows Plaintiffs and Settling Defendants to avoid the risks and costs of lengthy litigation and the uncertainty of pre-trial proceedings, a trial, and appeals. If approved, the Settlement would permit eligible Settling Class Members, who file timely and valid Claim Forms, to receive some compensation, rather than risk ultimately receiving nothing. Plaintiffs and Plaintiffs’ Lead Counsel believe the Settlement is in the best interest of all Settlement Class Members. The Settling Defendants have collectively agreed to pay $86.4 million (the “Settlement Amount”) in cash for the benefit of the proposed Settlement Class. If the Settlement is approved, the Settlement Amount, plus interest earned from the date it was established, less any Taxes, any Notice and Administration Costs, any Court-awarded attorneys’ fees, litigation costs and expenses, and service awards for Plaintiffs, and any other costs or fees approved by the Court (the “Net Settlement Fund”), will be divided among all Settling Class Members who file valid Claim Forms. If the Settlement is approved, the Action will conclude. If the Settlement is not approved, Settling Defendants will remain as defendants in the Action, and Plaintiffs will continue to pursue their claims against Settling Defendants. B.

CALL 1-877-829-2941 OR VISIT WWW.MGBANTITRUSTSETTLEMENT.COM PAGE 3 OF 9 On March 30, 2018, Plaintiffs Oklahoma Firefighters Pension & Retirement System and Electrical Workers Pension Fund Local 103, I.B.E.W. filed the first class action complaint in this Action against the Settling Defendants and other defendants. Five additional class action complaints relating to the same facts and circumstances of this Action were filed in May 2018 against Settling Defendants and other defendants. On June 18, 2018, the Court granted an order consolidating the six related class action complaints and appointing Lowey Dannenberg, P.C. as interim class counsel. Thereafter, on July 18, 2018, Plaintiffs filed a first amended consolidated class action complaint (“FAC”), adding Plaintiffs Manhattan and Bronx Surface Transit Operating Authority Pension Plan, Metropolitan Transportation Authority Defined Benefit Pension Plan Master Trust, Boston Retirement System, Southeastern Pennsylvania Transportation Authority Pension Plan, United Food and Commercial Workers Union and Participating Food Industry Employers Tri- State Pension Fund, and Government Employees’ Retirement System of the Virgin Islands. Defendants filed their motions to dismiss the FAC on September 17, 2018, which Plaintiffs opposed. On September 30, 2019, the Court granted Defendants’ motion to dismiss the FAC for failure to state a claim and directed Plaintiffs to file a letter seeking leave to file a further amended complaint within twenty-one days. Plaintiffs submitted a letter motion seeking leave to file a proposed Second Amended Class Action Complaint on October 21, 2019, to which Defendants responded. On October 25, 2019, the Court granted Plaintiffs’ letter motion, and on December 9, 2019, Plaintiffs filed a Second Amended Consolidated Class Action Complaint (“SAC”). Defendants filed their motion to dismiss the SAC on February 21, 2020, which Plaintiffs again opposed. On November 30, 2020, the Court granted Defendants’ motion to dismiss the SAC for lack of personal jurisdiction. On June 1, 2020, Plaintiffs filed their motion for preliminary approval of settlements with Barclays and JPMorgan, which the Court granted on December 16, 2020. On September 9, 2021, Plaintiffs filed their motion for final approval of the Barclays and JPMorgan settlements and Lead Counsel’s motion for attorneys’ fee and payment of expenses. The Court granted both motions and entered judgment in October 2021. On May 20, 2021, Plaintiffs filed their motion for reconsideration of the Court’s November 30, 2020 order dismissing the SAC, which the Court denied on March 30, 2022. On August 17, 2022, the Court entered judgment in favor of Bank of America Mexico, BBVA Bancomer, Citibanamex, Deutsche Bank Mexico, HSBC Mexico and Santander Meixco. Plaintiffs appealed the Court’s judgment and orders to the United States Court of Appeals for the Second Circuit on September 15, 2022. After the appeal was fully briefed and following oral argument, the Second Circuit vacated the Court’s judgment and remanded the case on February 9, 2024. The Court reopened the case on April 3, 2024, and Plaintiffs filed their Third Amended Complaint (“TAC”) on June 12, 2024. Settling Defendants filed a motion to dismiss the TAC on July 29, 2024, which Plaintiffs again opposed. After the motion was fully briefed, the Court denied Settling Defendants’ motion to dismiss the TAC on January 15, 2025. Settling Defendants thereafter filed their answers to the TAC. On May 11, 2026, Plaintiffs and Settling Defendants reached an agreement in principle to settle Plaintiffs’ claims against Settling Defendants for $86,400,000. Plaintiffs and Settling Defendants negotiated the material terms and executed the Settlement Agreement on August 12, 2026. The Court granted preliminary approval of the Settlement on August 19, 2026. Settling Defendants deny the allegations in the pleadings in the case, deny that they have engaged in any wrongdoing and vigorously dispute that Plaintiffs and the Class are entitled to any relief, but nevertheless agree to resolve the case to eliminate the uncertainties, burden, expense and delay of further litigation. C. The Definition of the Settlement Class In the Preliminary Approval Order, the Court preliminarily approved the following Settlement Class, defined as: All Persons that entered into a Mexican Government Bond Transaction with a Defendant or an affiliate of a Defendant between at least January 1, 2006, and April 19, 2017, where such persons were either domiciled in the United States or its territories or, if domiciled outside the United States or its territories, transacted in the United States or its territories. Excluded from the Class are Defendants and their employees, agents, affiliates, parents, subsidiaries and co-conspirators, whether or not named in the Complaint in this Action, and the United States and Mexican governments; provided, however, that Investment Vehicles shall not be excluded from the definition of “Class” or “Settlement Class” solely on the basis of being deemed to be Defendants or affiliates or subsidiaries of Defendants. Notwithstanding the sentence above that “[e]xcluded from the Class are the Defendants and their employees, agents, affiliates, parents, subsidiaries, and co-conspirators, whether or not named in the Complaint in this Action, and the United States and Mexican governments,” and solely for purposes of this Settlement and this Settlement Class, Investment Vehicles shall not be excluded from the Settlement Class solely on the basis of being deemed to be Defendants or affiliates or subsidiaries of Defendants; provided, however, that under no circumstances may a Defendant (or any of its direct or indirect parents, subsidiaries, affiliates, or divisions) receive a distribution from the Settlement Fund through an Investment Vehicle.

Settling Defendants’ Payments for the Benefit of the Settlement Class a. No Right to Reversion The Settlement Agreement does not provide Settling Defendants with a right of reversion. That is, no matter how many Class Members fail to file a Claim Form or choose to opt-out, if the Settlement is not terminated and is finally approved by the Court, none of the Settlement monies will revert to the Settling Defendants. This is not a claims-made settlement; there will be no reversion. b. Settling Defendants’ Potential Right To Termination Section 20 of the Settlement Agreement describes Settling Defendants’ right to terminate the Settlement if certain events occur. With respect to each such event, Settling Defendants have the right (as qualified in the Settlement Agreement), but not the obligation, to determine to exercise, in its sole discretion, its right to terminate if the event occurs. c. Distribution Plan The Distribution Plan is available for review on the Settlement Website at www.MGBAntitrustSettlement.com. Changes, if any, to the Distribution Plan based on newly available data or information will be promptly posted on the Settlement Website. Please see the Settlement Website for the most up-to-date information about the Distribution Plan. Members of the Settlement Class are strongly encouraged to review the Settlement Website for any changes to the Distribution Plan. d. Changes or Further Orders by the Court Any change by the Court of the Distribution Plan, the time and place of the Fairness Hearing, or any other matter and all further orders or requirements by the Court will be posted on the Settlement Website at www.MGBAntitrustSettlement.com as soon as practicable. It is important that you refer to the Settlement Website as no other notice may be published of such changes. 2. The Release and Covenant Not to Sue under the Settlement Agreement IF YOU HAVE NOT VALIDLY REQUESTED TO BE EXCLUDED FROM THE SETTLEMENT CLASS, WHEN THE SETTLEMENT BECOMES FINAL YOU WILL BE RELEASING THE CLAIMS DESCRIBED BELOW, AND YOU WILL BE BOUND BY THE RELEASES IN THE SETTLEMENT AGREEMENT INCLUDING THE COVENANT NOT TO SUE—EVEN IF YOU DO NOT FILE A PROOF OF CLAIM AND RELEASE.

Upon the Effective Date, the Releasing Parties shall release and be deemed to release and forever discharge and shall be forever enjoined from prosecuting the Released Claims against the Released Parties, regardless of whether such Releasing Party executes and delivers a Claim Form. The capitalized terms used in this paragraph are defined in the Settlement Agreement, Preliminary Approval Order, or this Notice. For easy reference, certain of these terms are copied below: • “Released Parties” or “Released Party” means Settling Defendants and each of their respective past and present direct and indirect corporate parents (including holding companies), subsidiaries, related entities, affiliates, associates (all as defined in SEC Rule 12b-2 promulgated pursuant to the Securities Exchange Act of 1934), divisions, joint ventures, predecessors, and successors, and each of their respective past or present officers, directors, partners, members, managers, managing directors, employees, agents, contractors, attorneys, legal or other representatives, trustees, trusts, heirs, beneficiaries, estates, executors, administrators, insurers, shareholders, advisors, and assigns of each of the foregoing. • “Releasing Parties” means, individually and collectively, Plaintiffs and each Settling Class Member, on behalf of themselves and any of their respective predecessors, successors and assigns, direct and indirect parents, subsidiaries and affiliates, and on behalf of their respective past or present officers, directors, stockholders, agents, employees, legal representatives, partners, principals, members, participants, associates, trustees, beneficiaries, parents, subsidiaries, divisions, QUESTIONS? CALL 1-877-829-2941 OR VISIT WWW.MGBANTITRUSTSETTLEMENT.COM PAGE 5 OF 9 affiliates, and the heirs, executors, administrators, purchasers, predecessors, successors, and assigns of each of the foregoing, whether or not they object to the Settlement and whether or not they make a claim for payment from the Net Settlement Fund. • “Released Claims” means any and all manner of claims, rights, demands, obligations, damages, actions or causes of action, cross-claims, counterclaims, judgments, suits, obligations, debts, setoffs, rights of recovery, charges or liabilities of any kind whatsoever (however denominated), of every nature and description, whether known or unknown, suspected or unsuspected, asserted or unasserted, whether class, derivative or individual, whether fixed or contingent, in law or in equity, whether arising under federal, state, common, statutory or foreign law or regulation (including Fed. R. Civ. P. 11), whether directly, representatively, derivatively, or in any other capacity, which any member of the Settlement Class ever had, now have, or hereafter can, shall, or may have that arise out of or relate in any way to the acts, facts, statements, or omissions that were or could have been alleged or asserted by Plaintiffs or any member of the Settlement Class in the Action, including, but not limited to, any claims arising from or related to (a) any purported conspiracy, collusion, racketeering activity, or other improper conduct related to Mexican Government Bonds or Mexican Government Bond Transactions, (b) any alleged manipulation of the prices of Mexican Government Bonds or Mexican Government Bond Transactions, or (c) the sharing or exchange of customer information or confidential information, including, but not limited to, customer identity, trading patterns, net positions, or orders with respect to Mexican Government Bonds or Mexican Government Bond Transactions. For the avoidance of doubt, Released Claims do not include claims relating to enforcement of the Settlement and do not include claims arising under foreign law based solely on transactions executed entirely outside of the United States by members of the Settlement Class domiciled outside the United States. You are automatically a member of a Settling Class if you fit the Settlement Class description. However, if you do not submit a timely and valid Claim Form, you will not receive any payment from the Settlement. You will be bound by past and any future Court rulings, including rulings on the Settlement and Released Claims. Unless you exclude yourself, you will not be able to start a lawsuit, continue with a lawsuit, or be a part of any other lawsuit against Settling Defendants or any of the other Released Parties on the basis of the Released Claims. ***** The Settlement Agreement does not settle or compromise any claims other than those set out therein.
