Page 16 2 PSLRA SUMMARY OF THE NOTICE Statement of the Settlement Class’s Recovery 1. Lead Plaintiffs have entered into the proposed Settlement with the Defendants which, if approved by the Court, will resolve the Action in its entirety. Subject to Court approval, Lead Plaintiffs, on behalf of the Settlement Class, have agreed to settle the Action in exchange for a payment of $85,000,000 in cash (the “Settlement Amount”), which will be deposited into an interest-bearing Escrow Account (the “Settlement Fund”). Based on Lead Plaintiffs’ consulting damages expert’s estimate of the number of shares of Everbridge publicly traded common stock eligible to participate in the Settlement, and assuming that all investors eligible to participate in the Settlement do so, it is estimated that the average recovery, before deduction of any Court-approved fees and expenses, such as attorneys’ fees, Litigation Expenses, Taxes, and Notice and Administration Expenses, would be approximately $2.32 per allegedly damaged share. If the Court approves Lead Counsel’s Fee and Expense Application (discussed below), the average recovery would be approximately $1.65 per allegedly damaged share. These average recovery amounts are only estimates and Settlement Class Members may recover more or less than these estimates. A Settlement Class Member’s actual recovery will depend on, for example: (i) the number and value of claims submitted; (ii) the amount of the Net Settlement Fund; (iii) when and how many shares of Everbridge publicly traded common stock the Settlement Class Member purchased; and (iv) whether and when the Settlement Class Member sold Everbridge publicly traded common stock. See the Plan of Allocation beginning on page 12 for information about the calculation of your Recognized Claim. Statement of Potential Outcome of Case if the Action Continued to Be Litigated 2. The Parties disagree about both liability and damages and do not agree about the amount of damages that would be recoverable if Lead Plaintiffs were to prevail on each claim. The issues on which the Parties disagree include, for example: (i) whether Defendants made any statements or omissions that were materially misleading or were otherwise actionable under the federal securities laws; (ii) whether any such statements or omissions were made with the requisite level of intent; (iii) the amount by which the price of Everbridge publicly traded common stock was allegedly artificially inflated, if at all, during the Class Period; and (iv) the extent to which factors such as general market, economic and industry conditions influenced the trading price of Everbridge publicly traded common stock at various times. 3. Defendants have denied and continue to deny any and all allegations of wrongdoing or fault asserted in the Action, deny that they have committed any act or omission giving rise to any liability or violation of law, and deny that Lead Plaintiffs and the Settlement Class have suffered any loss attributable to Defendants’ actions or omissions. Statement of Attorneys’ Fees and Expenses Sought 4. Lead Counsel, on behalf of Plaintiffs’ Counsel,2 will apply to the Court for attorneys’ fees from the Settlement Fund in an amount not to exceed 28% of the Settlement Fund, which includes any accrued interest, or $23,800,000, plus accrued interest. Lead Counsel will also apply for payment of Litigation Expenses incurred in prosecuting the Action in an amount not to exceed $675,000, plus accrued interest, which may include an application pursuant to the Private Securities Litigation Reform Act of 1995 (“PSLRA”) for the reasonable costs and expenses (including lost wages) of Plaintiffs directly related to their representation of the Settlement Class. If the Court approves Lead Counsel’s Fee and Expense Application in full, the average amount of fees and expenses is estimated to be approximately $0.67 per allegedly damaged share of Everbridge common stock. A copy of the Fee and Expense Application will be posted on www.EverbridgeSecuritiesSettlement.com after it has been filed with the Court. Reasons for the Settlement 5. For Lead Plaintiffs, the principal reason for the Settlement is the guaranteed cash benefit to the Settlement Class. This benefit must be compared to, among other factors, the uncertainty of being able to prove the allegations in the Operative Complaint and certify a litigation class; the difficulties and delays inherent in completing discovery; the risk that the Court may grant some or all of the anticipated summary judgment motions to be filed by Defendants; the risks of litigation, especially in complex securities actions like this; as well as the difficulties and delays inherent in such litigation (including any trial and appeals). For Defendants, who deny all allegations of wrongdoing or liability whatsoever and deny that Settlement Class Members were damaged, the principal reasons for entering into the Settlement are to end the burden, expense, uncertainty, and risk of further litigation. Accordingly, the Settlement may not be construed as an admission of any wrongdoing by Defendants. 2 “Plaintiffs’ Counsel” are Labaton Keller Sucharow LLP, Robbins Geller Rudman & Dowd LLP, and David M. Goldstein. 3 Identification of Representatives 6. Lead Plaintiffs and the Settlement Class are represented by Lead Counsel, Michael H. Rogers, Esq., Labaton Keller Sucharow LLP, 140 Broadway, New York, NY 10005, 888-219-6877, www.labaton.com, settlementquestions@labaton.com. 7. Further information regarding the Action, the Settlement, and this Notice may be obtained by contacting the Claims Administrator: Everbridge Securities Settlement, c/o Verita Global, LLC, P.O. Box 301170, Los Angeles, CA 90030-1170, 888-808-1850, www.EverbridgeSecuritiesSettlement.com. Please Do Not Call the Court with Questions About the Settlement. BASIC INFORMATION 1. Why did I get the Postcard Notice? 8. You may have received a Postcard Notice about the proposed Settlement. This long-form Notice provides additional information about the Settlement and related procedures. The Court authorized that the Postcard Notice be sent to you because you or someone in your family may have purchased or acquired Everbridge publicly traded common stock during the Class Period. Receipt of the Postcard Notice does not mean that you are a Member of the Settlement Class or that you will be entitled to receive a payment. The Parties to the Action do not have access to your individual investment information. If you wish to be eligible for a payment, you are required to submit the Claim Form that is available at www.EverbridgeSecuritiesSettlement.com. See Question 9 below. 9. The Court directed that the Postcard Notice be sent to Settlement Class Members because they have a right to know about the proposed Settlement of this class action lawsuit, and about all of their options, before the Court decides whether to approve the Settlement. 10. The Court in charge of the Action is the United States District Court for the Central District of California, and the case is known as Sylebra Capital Partners Master Fund LTD, et al. v. Everbridge, Inc., et al., No. 2:22-cv-02249- FWS-RAO (C.D. Cal.). The Action is assigned to the Honorable Fred W. Slaughter, United States District Judge. 2. How do I know if I am part of the Settlement Class? 11. The Court directed that everyone who fits the following description is a Settlement Class Member and subject to the Settlement, unless they are an excluded person (see Question 3 below) or take steps to exclude themselves from the Settlement Class (see Question 11 below): All persons and entities who or which purchased or otherwise acquired the publicly traded common stock of Everbridge during the period from February 18, 2020 through February 24, 2022, both dates inclusive, and were allegedly damaged thereby. 12. If one of your mutual funds purchased Everbridge publicly traded common stock during the Class Period, that does not make you a Settlement Class Member, although your mutual fund may be. You are a Settlement Class Member only if you individually purchased Everbridge publicly traded common stock during the Class Period. Check your investment records or contact your broker to see if you have any eligible purchases or acquisitions. The Parties to the Action do not independently have access to your trading information. 3. Are there exceptions to being included? 13. Yes. There are some individuals and entities who are excluded from the Settlement Class by definition. Excluded from the Settlement Class are: (i) Defendants; (ii) members of the Immediate Family of any Defendant who is an individual; (iii) any person who was an officer, director, or control person of Everbridge during the Class Period; (iv) any firm, trust, corporation, or other entity in which any Defendant has or had a controlling or beneficial interest; (v) Everbridge’s employee retirement and benefit plan(s) and their participants or beneficiaries, to the extent they made purchases through such plan(s); and (vi) the legal representatives, affiliates, heirs, successors-in-interest, or assigns of any such excluded person. Also excluded from the Settlement Class are those Persons who or which submit a timely and valid request for exclusion from the Settlement Class in accordance with the procedures described in Question 11 below. 4. Why is this a class action? 14. In a class action, one or more persons or entities (in this case, Lead Plaintiffs) sue on behalf of people and entities who have similar claims. Together, these people and entities are a “class,” and each is a “class member.” A class action allows one court to resolve, in a single case, many similar claims that, if brought separately by individual people, might be too small economically to litigate. One court resolves the issues for all class members at the same time, except for those who exclude themselves, or “opt out,” from the class. In this Action, the Court has appointed Sylebra Capital Partners Master Fund Ltd, Sylebra Capital Parc Master Fund, and Sylebra Capital Menlo Master Fund as Lead Plaintiffs and Labaton Keller Sucharow LLP to serve as Lead Counsel. 4 5. What is this case about and what has happened so far? 15. Everbridge was founded in 2002 as a company that offered a Mass Notification software, which sent messages via telephone, text, and email to an entire population in the event of a threat or emergency. To generate long-term growth, Everbridge developed a Critical Event Management suite, which it described as a collection of various products that enable organizations to assess, manage, and respond to distinct threats and emergencies, all on a single platform. 16. The case alleges that Defendants made materially misleading statements and omissions surrounding Everbridge’s acquisitions during the Class Period, including the acquisition of an IT service platform called xMatters. The Operative Complaint alleges that Defendants made allegedly false or misleading statements regarding the progress of Everbridge’s integration of these acquisitions and xMatters’ contribution to Everbridge’s revenue in 2021. 17. By an Order dated July 8, 2022, the Court: (i) appointed Sylebra Funds as Lead Plaintiffs; and (ii) approved Labaton Sucharow LLP (n/k/a Labaton Keller Sucharow LLP) (“Labaton”) as Lead Counsel and Robbins Geller Rudman & Dowd LLP (“Robbins Geller”) as Liaison Counsel. 18. Lead Plaintiffs, through Lead Counsel, conducted a thorough investigation relating to the claims, defenses, and underlying events and transactions that are the subject of the Action. This process has included reviewing and analyzing: (i) regulatory filings made by Everbridge with the U.S. Securities and Exchange Commission (“SEC”); (ii) Company press releases, transcripts of earnings calls, and other public statements issued and disseminated by the Company; (iii) Company website and marketing materials; (iv) price and volume data for Everbridge common stock; (v) research reports from securities and financial analysts; (vi) news and media reports concerning the Company and other facts related to this Action; (vii) interviews with approximately 40 former Everbridge employees (several of whom provided information used in complaints as confidential witnesses); (viii) consultation with experts on loss causation, damages, and accounting issues; (ix) other publicly available material and data; and (x) the applicable law governing the claims and potential defenses. 19. On September 16, 2022, Lead Plaintiffs filed an Amended Class Action Complaint for Violation of the Federal Securities Laws (“First Amended Complaint” or “FAC”), asserting claims pursuant to Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 (the “Exchange Act”) and Rule 10b-5 promulgated thereunder, against Everbridge, Jaime Ellertson, and the Individual Defendants. Among other things, the FAC alleged that defendants made materially false and misleading statements and omissions during the period from November 4, 2019 through February 24, 2022 concerning the integration of Everbridge’s acquisitions and the revenue contribution of xMatters. 20. On October 31, 2022, defendants filed their motion to dismiss the FAC, memorandum of points and authorities in support thereof, and related request for judicial notice. On December 15, 2022, Lead Plaintiffs filed their opposition to defendants’ motion to dismiss and response to defendants’ request for judicial notice. On January 17, 2023, defendants filed their reply in support of the motion to dismiss and request for judicial notice and filed a supplemental request for judicial notice. 21. On May 9, 2023, the Court issued an order granting defendants’ motion to dismiss the FAC without prejudice and with leave to amend. The Court in its order concluded that the FAC did not adequately plead the necessary elements of scienter or falsity and dismissed Lead Plaintiffs’ claims. 22. On June 30, 2023, Lead Plaintiffs filed a Second Amended Class Action Complaint for Violation of the Federal Securities Laws (“Second Amended Complaint” or “SAC”) asserting claims pursuant to Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 promulgated thereunder against Everbridge, Ellertson, and the Individual Defendants. 23. On August 14, 2023, defendants filed their second motion to dismiss and related request for judicial notice. On September 28, 2023, Lead Plaintiffs filed their opposition to defendants’ second motion to dismiss. On October 30, 2023, defendants filed their reply in support of the motion to dismiss and request for judicial notice. On January 4, 2024, the Court heard oral argument on defendants’ second motion to dismiss and took the motion under submission. 24. On March 18, 2024, the Court issued an order granting defendants’ motion to dismiss the SAC without prejudice and with leave to amend. The Court in its motion to dismiss order concluded the SAC did not adequately plead scienter or falsity and dismissed Lead Plaintiffs’ claims under Section 10(b) and Rule 10b-5, citing reasons similar to those in its order on defendants’ motion to dismiss the FAC. The order also dismissed the SAC’s Section 20(a) claim against the individual defendants. 5 25. On April 16, 2024, Lead Plaintiffs filed a notice of appeal to the United States Court of Appeals for the Ninth Circuit (the “Ninth Circuit”). 26. On October 8, 2024, Lead Plaintiffs submitted their opening brief with the Ninth Circuit. Defendants filed their answering brief on January 16, 2025. Lead Plaintiffs filed their reply brief on February 6, 2025. On May 20, 2025, the appeal regarding defendants’ motion to dismiss the SAC was argued by the parties in Pasadena, California before Ninth Circuit Judges Wardlaw, Graber, and Johnstone. 27. On July 15, 2025, the Ninth Circuit issued its decision, reversing and remanding, in part, the order of the Court dismissing the SAC. The Ninth Circuit held that Lead Plaintiffs adequately alleged scienter and falsity of certain statements but agreed with the Court that the SAC failed to adequately plead statements concerning Everbridge’s general acquisition strategy. In so holding, the Ninth Circuit also effectively shortened the class period to February 18, 2020 through February 24, 2022, inclusive. 28. On October 15, 2025, Lead Plaintiffs filed a revised Second Amended Class Action Complaint for Violation of the Federal Securities Laws. In accordance with the Ninth Circuit order, this complaint alleged claims arising during a class period of February 18, 2020 through February 24, 2022, inclusive. On November 10, 2025, Defendants Everbridge, Meredith, and Brickley filed their Answer to the complaint, and defendant Ellertson separately filed his Answer to the complaint. 29. On November 19, 2025, Defendant Ellertson filed a motion for judgment on the pleadings and memorandum of points and authorities in support thereof. On December 5, 2025, Lead Plaintiffs filed their opposition to Defendant Ellertson’s motion, and on December 16, 2025, Defendant Ellertson filed his reply in support of his motion. 30. On January 6, 2026, the parties filed a stipulation of dismissal of Defendant Ellertson with prejudice as to the Section 10(b) claim and without prejudice as to the Section 20(a) claim. On January 23, 2026, the parties filed a joint stipulation in support of the filing of a further revised complaint following the stipulation of dismissal of Defendant Ellertson. On January 26, 2026, the Court approved the joint stipulation and ordered Lead Plaintiffs to file a further revised version of the complaint and for Defendants to file an answer thereto. 31. On January 28, 2026, Lead Plaintiffs filed a Corrected Operative Second Amended Class Action Complaint for Violation of the Federal Securities Laws (the “Operative Complaint”) asserting claims pursuant to Sections 10(b) and 20(a) of the Exchange Act and Rule 10b-5 promulgated thereunder against Everbridge, Meredith and Brickley. On February 9, 2026, Defendants Everbridge, Meredith, and Brickley filed their answer to the Operative Complaint. 32. On March 12, 2026, Lead Plaintiffs and proposed additional class representative Central Laborers’ Pension Fund (“Central Laborers”) filed their motion for class certification and appointment of class representatives and co- class counsel (the “Class Certification Motion”). Thereafter, Defendants deposed Lead Plaintiffs and Central Laborers, Central Laborers’ external investment manager, and their loss causation and market efficiency expert. On May 18, 2026, Defendants filed their opposition to the Class Certification Motion. Lead Plaintiffs were preparing their reply brief in further support of the Class Certification Motion when the Parties agreed to settle the Action. 33. In connection with fact discovery, Lead Plaintiffs and Defendants served and responded to multiple requests for the production of documents and interrogatories, respectively, which included responses and objections thereto. Lead Plaintiffs also noticed the depositions of six former Everbridge employees, and prepared to take depositions of those individuals. Lead Plaintiffs also prepared to take the deposition of Everbridge’s Rule 30(b)(6) deponent. 34. In connection with formal discovery, Defendants produced approximately 201,000 documents (approximately 1,032,000 pages) to Plaintiffs, and Plaintiffs produced approximately 15,000 documents (approximately 102,000 pages) to Defendants. Additionally, third parties produced approximately 6,100 documents (approximately 51,000 pages). In total, approximately 222,100 documents (approximately 1,185,000 pages) were produced by the Parties and third parties in formal discovery. 35. The Parties began exploring the possibility of a negotiated resolution in the Spring of 2026. Specifically, the Parties agreed to participate in a mediation and retained David M. Murphy of Phillips ADR Enterprises to act as the mediator in the case (the “Mediator”). On June 1, 2026, Plaintiffs’ Counsel and Defendants’ Counsel, among others, participated in a full-day, in-person mediation session before the Mediator. In advance of that session, the Parties submitted detailed mediation statements to the Mediator, together with numerous supporting exhibits. 6 36. The June 1, 2026 mediation session ended without an agreement being reached. The Parties continued discussions with the Mediator following the mediation to further explore the possibility of a settlement. 37. On June 13, 2026, the Parties accepted the Mediator’s double-blind recommendation and, in so agreeing, reached a settlement-in-principle to resolve all claims in the Action, and related claims, on a class-wide basis for $85,000,000 in cash. 38. The Parties’ settlement in principle was subsequently memorialized in a confidential term sheet executed and finalized as of July 8, 2026 (the “Term Sheet”), subject to the execution of a customary “long form” stipulation and agreement of settlement and related papers. The Stipulation was executed as of August 10, 2026. 6. What are the reasons for the Settlement? 39. The Court did not finally decide in favor of Lead Plaintiffs or Defendants. Instead, both sides agreed to a settlement. Lead Plaintiffs and Lead Counsel believe that the claims asserted in the Action have merit. They recognize, however, the expense and length of continued proceedings needed to pursue the claims through trial and appeals, as well as the difficulties in establishing liability and damages. Assuming the claims proceeded to trial, the Parties would present factual and expert testimony on each of the disputed issues, and there is risk that the Court or jury would resolve these issues unfavorably against Lead Plaintiffs and the class. In light of the Settlement and the guaranteed cash recovery to the Settlement Class, Lead Plaintiffs and Lead Counsel believe that the proposed Settlement is fair, reasonable, and adequate, and in the best interests of the Settlement Class. 40. Defendants have denied and continue to deny any and all allegations of wrongdoing or liability arising out of any of the conduct, statements, acts or omissions alleged, or that could have been alleged, in the Action, including, but not limited to, all contentions concerning Defendants’ business, conduct and public statements, as well as contentions that any such conduct or events constitute wrongdoing or give rise to legal liability. Defendants also have denied and continue to deny, inter alia, the allegations that Lead Plaintiffs or Settlement Class Members have suffered damages or were otherwise harmed in any way by any of the Defendants or by the conduct alleged in the Action. Defendants further have asserted and continue to assert that, at all times, they acted in good faith and in a manner they reasonably believed to be in accordance with applicable rules, regulations, and laws. Nonetheless, Defendants have concluded that continuation of the Action would be protracted and expensive, and have taken into account the uncertainty and risks inherent in any litigation, especially a complex case like this Action. THE SETTLEMENT BENEFITS 7. What does the Settlement provide? 41. In exchange for the Settlement and the release of the Released Plaintiffs’ Claims against the Released Defendant Parties (see Question 10 below), Defendants have agreed to pay, or cause the payment of, $85,000,000, which, along with any interest earned, will be distributed, after deduction of Court-awarded attorneys’ fees and Litigation Expenses, Notice and Administration Expenses, Taxes, and any other fees or expenses approved by the Court (the “Net Settlement Fund”), to Settlement Class Members who submit valid and timely Claim Forms and are found to be eligible to receive a distribution from the Net Settlement Fund. 8. What might happen if there were no Settlement? 42. If there were no Settlement and Plaintiffs failed to establish any essential legal or factual element of their claims against Defendants, neither Plaintiffs nor the other Settlement Class Members would recover anything from Defendants. Also, if Defendants were successful in proving any of their defenses, either at trial or on appeal, the Settlement Class could recover less than the amount provided in the Settlement, or nothing at all. 9. How can I receive a payment? 43. To qualify for a payment from the Net Settlement Fund, you must submit a timely and valid Claim Form. A Claim Form may be obtained from the websites www.EverbridgeSecuritiesSettlement.com and www.labaton.com or you can submit a claim online at www.EverbridgeSecuritiesSettlement.com. You can also request that a Claim Form be mailed to you by calling the Claims Administrator toll-free at 888-808-1850. 44. Please read the instructions contained in the Claim Form carefully, fill out the form, include all the documents the form requests, sign it, and mail or submit it online to the Claims Administrator so that it is postmarked or received no later than November 25, 2026. 7 10. What am I giving up to receive a payment and by staying in the Settlement Class? 45. If you are a Settlement Class Member and do not timely and validly exclude yourself from the Settlement Class, you will remain in the Settlement Class and that means that, upon the Effective Date of the Settlement, you will release all Released Plaintiffs’ Claims against the Released Defendant Parties. All of the Court’s orders about the Settlement, whether favorable or unfavorable, will apply to you and legally bind you. (a) “Released Plaintiffs’ Claims” means any and all claims and causes of action of every nature and description, whether known or Unknown Claims (as defined herein), suspected or unsuspected, contingent or absolute, mature or not mature, liquidated or unliquidated, accrued or not accrued, concealed or hidden, regardless of legal or equitable theory and whether arising under federal, state, common, or foreign law that Lead Plaintiffs or any other member of the Settlement Class: (a) asserted in the Action or (b) could have asserted in the Action, or in any forum, that arise out of or are based upon both: (i) the allegations, acts, transactions, facts, matters or occurrences, representations or omissions involved, set forth, or referred to in any complaint filed in the Action, and (ii) the purchase or acquisition of Everbridge publicly traded common stock during the Class Period. For the avoidance of doubt, Released Plaintiffs’ Claims shall not include claims to enforce the Settlement. (b) “Released Defendant Parties” means Defendants, Jaime Ellertson, and each of their respective former, present or future parents, subsidiaries, divisions, controlling persons, associates, related entities, and affiliates and each and all of their respective present and former employees, members, partners, principals, officers, directors, controlling shareholders, agents, attorneys, advisors (including financial or investment advisors), accountants, auditors, consultants, underwriters, investment bankers, commercial bankers, general or limited partners or partnerships, limited liability companies, members, joint ventures, insurers and reinsurers, predecessors, successors, estates, Immediate Family Members, heirs, executors, trustees, administrators, legal representatives, and assigns, in their capacities as such; and the predecessors, successors, estates, Immediate Family Members, heirs, executors, trustees, administrators, agents, legal representatives, and assigns of each of them, in their capacities as such, as well as any trust of which any Released Defendant Party is the settlor or which is for the benefit of any of their Immediate Family Members. (c) “Unknown Claims” means any and all Released Plaintiffs’ Claims that Lead Plaintiffs, or any other Settlement Class Member, does not know or suspect to exist in his, her, or its favor at the time of the release of the Released Defendant Parties, and any and all Released Defendants’ Claims that any Defendant does not know or suspect to exist in his, her, or its favor at the time of the release of the Released Plaintiff Parties, which if known by him, her, or it might have affected his, her, or its decision(s) with respect to the Settlement, including the decision to object to the terms of the Settlement or to exclude himself, herself, or itself from the Settlement Class. With respect to any and all Released Plaintiffs’ Claims and Released Defendants’ Claims, the Parties stipulate and agree that, upon the Effective Date, Lead Plaintiffs and Defendants shall expressly, and each other Settlement Class Member shall be deemed to have, and by operation of the Judgment or Alternative Judgment shall have, to the fullest extent permitted by law, expressly waived and relinquished any and all provisions, rights, and benefits conferred by any law of any state or territory of the United States or foreign law, or principle of common law, which is similar, comparable, or equivalent to Cal. Civ. Code § 1542, which provides: A general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her favor at the time of executing the release and that, if known by him or her, would have materially affected his or her settlement with the debtor or released party. Lead Plaintiffs, other Settlement Class Members, or Defendants may hereafter discover facts, legal theories, or authorities in addition to or different from those which any of them now knows or believes to be true with respect to the Action, the Released Plaintiffs’ Claims or the Released Defendants’ Claims, but Lead Plaintiffs and Defendants shall expressly, fully, finally, and forever settle and release, and each Settlement Class Member shall be deemed to have fully, finally, and forever settled and released, and upon the Effective Date and by operation of the Judgment or Alternative Judgment shall have settled and released, fully, finally, and forever, any and all Released Plaintiffs’ Claims and Released Defendants’ Claims as applicable, without regard to the subsequent discovery or existence of such different or additional facts, legal theories, or authorities. Lead Plaintiffs and Defendants acknowledge, and other Settlement Class Members by operation of law shall be deemed to have acknowledged, that the inclusion of “Unknown Claims” in the definition of Released Plaintiffs’ Claims and Released Defendants’ Claims was separately bargained for and was a material element of the Settlement. (d) The “Effective Date” will occur when an Order entered by the Court approving the Settlement becomes Final and is not subject to appeal (see Stipulation at ¶39). 46. Upon the Effective Date, Defendants will also provide a release of any claims against Plaintiffs, the Settlement Class, and Plaintiffs’ Counsel in accordance with the terms of the Stipulation. 8 EXCLUDING YOURSELF FROM THE SETTLEMENT CLASS 47. If you want to keep any right you may have to sue or continue to sue Defendants and the other Released Defendant Parties on your own concerning the Released Plaintiffs’ Claims, then you must take steps to remove yourself from the Settlement Class. This is called excluding yourself or “opting out.” Please note: If you decide to exclude yourself from the Settlement Class, there is a risk that any lawsuit you may file to pursue claims alleged in the Action may be dismissed, including because the suit is not filed within the applicable time periods required for filing suit. Defendants have the option to terminate the Settlement if a certain amount of Settlement Class Members request exclusion. 11. How do I exclude myself from the Settlement Class? 48. To exclude yourself from the Settlement Class, you must mail a signed letter stating that you request to be “excluded from the Settlement Class in Sylebra Capital Partners Master Fund LTD, et al. v. Everbridge, Inc., et al., No. 2:22-cv-02249-FWS-RAO (C.D. Cal.).” You cannot exclude yourself by telephone or email. Each request for exclusion must also: (i) state the name, address, telephone number, and email address (if any) of the Person seeking exclusion; (ii) state the date(s), price(s), and number(s) of shares of all purchases and sales of Everbridge publicly traded common stock during the Class Period; (iii) state the number of shares held at the opening of trading on February 18, 2020 and the close of trading on May 25, 2022; and (iv) be signed by the Person requesting exclusion. A request for exclusion must be mailed so that it is received no later than November 25, 2026 at: Everbridge Securities Settlement c/o Verita Global, LLC EXCLUSIONS P.O. Box 301170 Los Angeles, CA 90030-1170 49. This information is needed to determine whether you are a member of the Settlement Class. Your exclusion request must comply with these requirements in order to be valid. 50. If you ask to be excluded, do not submit a Claim Form because you cannot receive any payment from the Net Settlement Fund. Also, you cannot object to the Settlement because you will not be a Settlement Class Member and the Settlement will not affect you. If you submit a timely and valid exclusion request, you will not be legally bound by anything that happens in the Action, and you may be able to sue (or continue to sue) Defendants and the other Released Defendant Parties in the future. 12. If I do not exclude myself, can I sue Defendants and the other Released Defendant Parties for the same reasons later? 51. No. Unless you properly exclude yourself, you will give up any rights to sue Defendants and the other Released Defendant Parties for any and all Released Plaintiffs’ Claims. If you have a pending lawsuit against any of the Released Defendant Parties, speak to your lawyer in that case immediately. You must exclude yourself from this Settlement Class to continue your own lawsuit. Remember, the exclusion deadline is November 25, 2026. THE LAWYERS REPRESENTING YOU 13. Do I have a lawyer in this case? 52. Labaton Keller Sucharow LLP is Lead Counsel in the Action and represents all Settlement Class Members. You will not be separately charged for these lawyers. The Court will determine the amount of attorneys’ fees and Litigation Expenses, which will be paid from the Settlement Fund. If you want to be represented by your own lawyer, you may hire one at your own expense. 14. How will the lawyers be paid? 53. Lead Counsel, together with the other Plaintiffs’ Counsel, has been prosecuting the Action on a contingent basis and has not been paid for any of its work. Lead Counsel, on behalf of itself and the other Plaintiffs’ Counsel, will seek an attorneys’ fee award of no more than 28% of the Settlement Fund, which will include accrued interest. Lead Counsel has agreed to share the awarded attorneys’ fees with other Plaintiffs’ Counsel. Lead Counsel will also seek payment of Litigation Expenses incurred by Plaintiffs’ Counsel in the prosecution of the Action of no more than $675,000, plus accrued interest, which may include an application in accordance with the PSLRA for the reasonable costs and expenses (including lost wages) of Plaintiffs directly related to their representation of the Settlement Class. As explained above, any attorneys’ fees and expenses awarded by the Court will be paid from the Settlement Fund. 9 OBJECTING TO THE SETTLEMENT, THE PLAN OF ALLOCATION, OR THE FEE AND EXPENSE APPLICATION 15. How do I tell the Court that I do not like something about the proposed Settlement? 54. If you are a Settlement Class Member, you can object to the Settlement or any of its terms, the proposed Plan of Allocation of the Net Settlement Fund, and/or Lead Counsel’s Fee and Expense Application. You may write to the Court about why you think the Court should not approve any or all of the Settlement terms or related relief. If you would like the Court to consider your views, you must file a proper objection within the deadline, and according to the following procedures. 55. To object, you must send a signed letter stating that you object to the proposed Settlement, the Plan of Allocation, and/or the Fee and Expense Application in “Sylebra Capital Partners Master Fund LTD, et al. v. Everbridge, Inc., et al., No. 2:22-cv-02249-FWS-RAO (C.D. Cal.).” The objection must also: (i) state the name, address, telephone number, and email address (if any) of the objector and must be signed by the objector; (ii) state the objection(s) and the specific reasons for each objection, including whether it applies only to the objector, to a specific subset of the Settlement Class, or to the entire Settlement Class, and any legal and evidentiary support, and witnesses, the Settlement Class Member wishes to bring to the Court’s attention; and (iii) include documents sufficient to show the objector’s membership in the Settlement Class, including the number of shares of Everbridge publicly traded common stock purchased and sold during the Class Period, as well as the dates and price per share of each such purchase and/or sale. Objectors who are represented by counsel must also provide the name, address, and telephone number of all counsel, if any, who represent them; the number of times the objector and their counsel have filed an objection to a class action settlement in the last five years; the nature of each such objection in each such case; and the name and docket number of each such case. Unless otherwise ordered by the Court, any Settlement Class Member who does not object in the manner described in this Notice will be deemed to have waived any objection and will be unable to make any objection to the proposed Settlement, the Plan of Allocation, and/or Lead Counsel’s Fee and Expense Application. 56. Your objection must be filed with the Court no later than November 25, 2026 and be mailed or delivered to the following counsel so that it is received no later than November 25, 2026: Court Lead Counsel Defendants’ Counsel Clerk of the Court Labaton Keller Sucharow LLP Kirkland & Ellis LLP U.S. District Court Michael H. Rogers, Esq. Jules H. Cantor, Esq. Central District of California 140 Broadway 333 W. Wolf Point Plaza Ronald Reagan Federal Building New York, NY 10005 Chicago, IL 60654 United States Courthouse Courtroom 10D, 10th Floor 411 W. 4th St Santa Ana, CA 92701 57. You do not need to attend the Settlement Hearing to have your written objection considered by the Court. However, any Settlement Class Member who has complied with the procedures described in this Question 15 and below in Question 19 may appear at the Settlement Hearing and be heard about their objection, to the extent allowed by the Court. An objector may appear in person or arrange, at his, her, or its own expense, for a lawyer to represent him, her, or it at the Settlement Hearing. 16. What is the difference between objecting and seeking exclusion? 58. Objecting is telling the Court that you do not like something about the proposed Settlement, Plan of Allocation, or Lead Counsel’s Fee and Expense Application. You can still recover money from the Settlement. You can object only if you stay in the Settlement Class. Excluding yourself is telling the Court that you do not want to be part of the Settlement Class. If you exclude yourself from the Settlement Class, you have no basis to object because the Settlement and the Action no longer affect you. 10 THE SETTLEMENT HEARING 17. When and where will the Court decide whether to approve the Settlement? 59. The Court will hold the Settlement Hearing on December 17, 2026 at 10:00 a.m. (Pacific Time) at the United States District Court for the Central District of California, Ronald Reagan Federal Building and United States Courthouse, Courtroom 10D, 10th Floor, 411 W. 4th St, Santa Ana, CA 92701. 60. At this hearing, the Honorable Fred W. Slaughter will consider whether: (i) the Settlement is fair, reasonable, adequate, and should be approved; (ii) the Plan of Allocation is fair and reasonable, and should be approved; and (iii) the application for an award of attorneys’ fees and payment of Litigation Expenses is reasonable and should be approved. The Court will take into consideration any written objections filed in accordance with the instructions in Question 15 above. We do not know how long it will take the Court to make these decisions. 61. The Court may change the date and time of the Settlement Hearing, or hold the hearing remotely, without another individual notice being sent to Settlement Class Members. If you want to attend the hearing, you should check with Lead Counsel beforehand to be sure that the date and/or time has not changed, or periodically check the Settlement website at www.EverbridgeSecuritiesSettlement.com to see if the Settlement Hearing has stayed as scheduled or has changed. 18. Do I have to come to the Settlement Hearing? 62. No. Lead Counsel will answer any questions the Court may have. But, you are welcome to attend at your own expense. If you submit a valid and timely objection, the Court will consider it and you do not have to come to Court to discuss it. You may have your own lawyer attend (at your own expense), but it is not required. If you do hire your own lawyer, he or she must file and serve a Notice of Appearance in the manner described in the answer to Question 19 below no later than November 25, 2026. 19. May I speak at the Settlement Hearing? 63. You may ask the Court for permission to speak at the Settlement Hearing. To do so, you must, no later than November 25, 2026, submit a statement that you, or your attorney, intend to appear in “Sylebra Capital Partners Master Fund LTD, et al. v. Everbridge, Inc., et al., No. 2:22-cv-02249-FWS-RAO (C.D. Cal.).” If you intend to present evidence at the Settlement Hearing, you must also include in your objections (prepared and submitted according to the answer to Question 15 above) the identities of any witnesses you may wish to call to testify and any exhibits you intend to introduce into evidence at the Settlement Hearing. You may not speak at the Settlement Hearing if you exclude yourself from the Settlement Class or if you have not provided written notice of your intention to speak at the Settlement Hearing in accordance with the procedures described in this Question 19 and in Question 15 above. IF YOU DO NOTHING 20. What happens if I do nothing at all? 64. If you do nothing and you are a member of the Settlement Class, you will receive no money from this Settlement and you will be precluded from starting a lawsuit, continuing with a lawsuit, or being part of any other lawsuit against Defendants and the other Released Defendant Parties concerning the Released Plaintiffs’ Claims. To share in the Net Settlement Fund, you must submit a Claim Form (see Question 9 above). To start, continue, or be a part of any other lawsuit against Defendants and the other Released Defendant Parties concerning the Released Plaintiffs’ Claims, you must exclude yourself from the Settlement Class (see Question 11 above). GETTING MORE INFORMATION 21. Are there more details about the Settlement? 65. This Notice summarizes the proposed Settlement. More details are in the Stipulation.

Please do not call the Court with questions about the Settlement. 11 PLAN OF ALLOCATION OF THE NET SETTLEMENT FUND 22. How will my claim be calculated? 67. As discussed above, the Settlement Amount and any interest it earns constitute the Settlement Fund. The Settlement Fund, after the deduction of Court-approved attorneys’ fees and Litigation Expenses, Notice and Administration Expenses, Taxes, and any other fees or expenses approved by the Court, is the Net Settlement Fund. If the Settlement is approved by the Court, the Net Settlement Fund will be distributed to Authorized Claimants – i.e., members of the Settlement Class who timely submit valid Claim Forms that are accepted for payment – in accordance with the following proposed Plan of Allocation, or such other plan of allocation as the Court may approve. Settlement Class Members who do not timely submit valid Claim Forms will not share in the Net Settlement Fund but will otherwise be bound by the Settlement. The Court may approve this proposed Plan of Allocation, or modify it, without additional individual notice to the Settlement Class. Any order modifying the Plan of Allocation will be posted on www.EverbridgeSecuritiesSettlement.com and www.labaton.com. 68. The objective of this Plan of Allocation is to distribute the Net Settlement Fund equitably among those Settlement Class Members who allegedly suffered economic losses as a result of the alleged violations of the federal securities laws during the Class Period. To design the Plan of Allocation, Lead Counsel conferred with Lead Plaintiffs’ consulting damages expert. The Plan of Allocation, however, is not a formal damages analysis. The calculations made pursuant to the Plan of Allocation are not intended to estimate, or be indicative of, the amounts that Settlement Class Members might have been able to recover as damages after a trial. The calculations, including the Recognized Loss formulas, are also not intended to estimate the amounts that will be paid to Authorized Claimants. The computations under the Plan of Allocation are only a method to weigh the claims of Authorized Claimants against one another for the purposes of making pro rata allocations of the Net Settlement Fund and the Recognized Claim amounts are the basis upon which the Net Settlement Fund will be proportionately allocated to Authorized Claimants. An individual Settlement Class Member’s recovery will depend on, for example: (i) the total number and value of claims submitted; (ii) when the Claimant purchased or acquired Everbridge publicly traded common stock; and (iii) whether and when the Claimant sold his, her, or its Everbridge publicly traded common stock. The Claims Administrator will determine each Authorized Claimant’s pro rata share of the Net Settlement Fund based upon each Authorized Claimant’s “Recognized Claim.” 69. For losses to be compensable damages under the federal securities laws, the disclosure of the allegedly misrepresented information must be the cause of the decline in the price of the securities at issue. In this case, Lead Plaintiffs allege that Defendants issued false statements and omitted material facts during the Class Period which allegedly artificially inflated the price of Everbridge common stock. It is alleged that corrective information released to the market after market close on December 9, 2021 and February 24, 2022, negatively impacted the market price of Everbridge common stock on December 10, 2021 and on February 25, 2022 in a statistically significant manner and removed alleged artificial inflation from the price of Everbridge publicly traded common stock on those days. Accordingly, in order to have a compensable loss in this Settlement, Everbridge publicly traded common stock must have been purchased or acquired during the Class Period and held through at least one of the alleged corrective disclosure dates listed above. CALCULATION OF RECOGNIZED LOSS AMOUNTS 70. For purposes of determining whether a Claimant has a Recognized Claim, purchases, acquisitions, and sales of Everbridge publicly traded common stock will first be matched on a First In/First Out (“FIFO”) basis. Class Period sales will be matched first against any holdings at the beginning of the Class Period and then against purchases/acquisitions in chronological order, beginning with the earliest purchase/acquisition made during the Class Period. 71. A “Recognized Loss Amount” will be calculated as set forth herein for each purchase of Everbridge publicly traded common stock during the Class Period (February 18, 2020 through February 24, 2022) that is listed in the Claim Form and for which adequate documentation is provided. To the extent that the calculation of a Claimant’s Recognized Loss Amount results in a negative number (a gain), that number shall be set to zero. 72. For each share of Everbridge publicly traded common stock purchased or otherwise acquired during the Class Period and sold before the close of trading on May 25, 2022, an “Out of Pocket Loss” will be calculated. Out of Pocket Loss is defined as the purchase price (excluding all fees, taxes, and commissions) minus the sale price (excluding all fees, taxes, and commissions). To the extent that the calculation of the Out of Pocket Loss results in a negative number (a gain), that number shall be set to zero. 73. The sum of a Claimant’s Recognized Loss Amounts will be the Claimant’s “Recognized Claim.” 74. For each share of Everbridge publicly traded common stock purchased from February 18, 2020 through and including February 24, 2022, and: A. Sold before December 10, 2021, the Recognized Loss Amount for each share shall be zero. B. Sold from December 10, 2021 through February 24, 2022, the Recognized Loss Amount for each share shall be the lesser of: 12 i. the alleged dollar artificial inflation applicable to each such share on the date of purchase/acquisition as set forth in Table 1 below minus the alleged dollar artificial inflation applicable to each such share on the date of sale as set forth in Table 1 below; or ii. the Out of Pocket Loss. C. Sold from February 25, 2022 through May 25, 2022, the Recognized Loss Amount for each such share shall be the least of: i. the alleged dollar artificial inflation applicable to each such share on the date of purchase/acquisition as set forth in Table 1 below; or ii. the actual purchase/acquisition price of each such share minus the average closing price from February 25, 2022, up to the date of sale as set forth in Table 2 below; or iii. the Out of Pocket Loss. D. Held as of the close of trading on May 25, 2022, the Recognized Loss Amount for each such share shall be the lesser of: i. the alleged dollar artificial inflation applicable to each such share on the date of purchase/acquisition as set forth in Table 1 below; or ii. the actual purchase/acquisition price of each such share minus $42.16.3 TABLE 1 Everbridge Publicly Traded Common Stock Alleged Artificial Inflation for Purposes of Calculating Purchase and Sale Inflation Transaction Date Alleged Artificial Inflation Per Share February 18, 2020 - December 9, 2021 $70.76 December 10, 2021 - February 24, 2022 $16.29 TABLE 2 Everbridge Publicly Traded Common Stock Closing Price and Average Closing Price February 25, 2022 – May 25, 2022 Average Closing Average Closing Price From Price From Closing February 25, 2022 Closing February 25, 2022 Date Price to Date Shown Date Price to Date Shown 2/25/2022 $30.61 $30.61 4/12/2022 $50.50 $41.21 2/28/2022 $39.52 $35.07 4/13/2022 $51.50 $41.51 3/1/2022 $38.29 $36.14 4/14/2022 $49.80 $41.75 3/2/2022 $37.98 $36.60 4/18/2022 $48.58 $41.94 3/3/2022 $36.81 $36.64 4/19/2022 $49.87 $42.15 3/4/2022 $36.46 $36.61 4/20/2022 $48.17 $42.31 3/7/2022 $35.56 $36.46 4/21/2022 $46.63 $42.42 3/8/2022 $36.19 $36.43 4/22/2022 $45.74 $42.51 3 Pursuant to Section 21D(e)(1) of the Exchange Act, “in any private action arising under this title in which the plaintiff seeks to establish damages by reference to the market price of a security, the award of damages to the plaintiff shall not exceed the difference between the purchase or sale price paid or received, as appropriate, by the plaintiff for the subject security and the mean trading price of that security during the 90-day period beginning on the date on which the information correcting the misstatement or omission that is the basis for the action is disseminated to the market.” Consistent with the requirements of the Exchange Act, Recognized Loss Amounts are reduced to an appropriate extent by taking into account the closing prices of Everbridge common stock during the “90-day look-back period,” February 25, 2022 through May 25, 2022. The mean (average) closing price for Everbridge common stock during this 90-day look-back period was $42.16. 13 Average Closing Average Closing Price From Price From Closing February 25, 2022 Closing February 25, 2022 Date Price to Date Shown Date Price to Date Shown 3/9/2022 $37.22 $36.52 4/25/2022 $47.18 $42.62 3/10/2022 $36.06 $36.47 4/26/2022 $45.35 $42.69 3/11/2022 $32.80 $36.14 4/27/2022 $44.27 $42.72 3/14/2022 $31.45 $35.75 4/28/2022 $45.81 $42.79 3/15/2022 $33.98 $35.61 4/29/2022 $43.10 $42.80 3/16/2022 $36.59 $35.68 5/2/2022 $46.67 $42.88 3/17/2022 $41.35 $36.06 5/3/2022 $46.01 $42.95 3/18/2022 $40.86 $36.36 5/4/2022 $46.89 $43.03 3/21/2022 $42.19 $36.70 5/5/2022 $43.01 $43.03 3/22/2022 $44.01 $37.11 5/6/2022 $39.94 $42.97 3/23/2022 $44.45 $37.49 5/9/2022 $35.82 $42.83 3/24/2022 $45.18 $37.88 5/10/2022 $38.21 $42.74 3/25/2022 $43.05 $38.12 5/11/2022 $36.94 $42.63 3/28/2022 $43.13 $38.35 5/12/2022 $37.63 $42.54 3/29/2022 $46.91 $38.72 5/13/2022 $40.73 $42.51 3/30/2022 $44.96 $38.98 5/16/2022 $38.24 $42.43 3/31/2022 $43.64 $39.17 5/17/2022 $38.61 $42.36 4/1/2022 $44.60 $39.38 5/18/2022 $38.57 $42.30 4/4/2022 $48.19 $39.71 5/19/2022 $40.71 $42.27 4/5/2022 $46.74 $39.96 5/20/2022 $41.18 $42.25 4/6/2022 $46.39 $40.18 5/23/2022 $40.95 $42.23 4/7/2022 $47.45 $40.42 5/24/2022 $39.25 $42.18 4/8/2022 $47.31 $40.64 5/25/2022 $40.91 $42.16 4/11/2022 $49.53 $40.92 14 ADDITIONAL PROVISIONS 75. Purchases, acquisitions, and sales of Everbridge common stock shall be deemed to have occurred on the “contract” or “trade” date as opposed to the “settlement” or “payment” or “sale” date. The receipt or grant by gift, inheritance, or operation of law of Everbridge common stock during the Class Period shall not be deemed a purchase, acquisition, or sale for the calculation of a Claimant’s Recognized Claim, nor shall the receipt or grant be deemed an assignment of any claim relating to the purchase or acquisition of such shares of Everbridge common stock unless: (i) the donor or decedent purchased or otherwise acquired such shares of Everbridge common stock during the Class Period; (ii) no Claim Form was submitted by or on behalf of the donor, on behalf of the decedent, or by anyone else with respect to such shares of Everbridge common stock; and (iii) it is specifically so provided in the instrument of gift or assignment. 76. In accordance with the Plan of Allocation, the Recognized Loss Amount on any portion of a purchase or acquisition that matches against (or “covers”) a “short sale” is zero. The Recognized Loss Amount on a “short sale” that is not covered by a purchase or acquisition is also zero. If a Claimant has an opening short position in Everbridge common stock at the start of the Class Period, the earliest Class Period purchases or acquisitions shall be matched against such opening short position in accordance with the FIFO matching described above and any portion of such purchases or acquisitions that covers such short sales will not be entitled to recovery. If a Claimant newly establishes a short position during the Class Period, the earliest subsequent Class Period purchase or acquisition shall be matched against such short position on a FIFO basis and will not be entitled to a recovery. 77. Everbridge publicly traded common stock purchased or acquired from February 18, 2020 through February 24, 2022, both dates inclusive, is the only security eligible for a recovery under the Plan of Allocation. With respect to Everbridge publicly traded common stock purchased or sold through the exercise of an option, the purchase/sale date of the Everbridge common stock is the exercise date of the option, and the purchase/sale price is the exercise price of the option. 78. An Authorized Claimant’s Recognized Claim shall be the amount used to calculate the Authorized Claimant’s pro rata share of the Net Settlement Fund. If the sum total of Recognized Claims of all Authorized Claimants who are entitled to receive payment out of the Net Settlement Fund is greater than the Net Settlement Fund, each Authorized Claimant shall receive his, her, or its pro rata share of the Net Settlement Fund. The pro rata share shall be the Authorized Claimant’s Recognized Claim divided by the total of Recognized Claims of all Authorized Claimants, multiplied by the total amount in the Net Settlement Fund. 79. If the Net Settlement Fund exceeds the sum total amount of the Recognized Claims of all Authorized Claimants entitled to receive payment out of the Net Settlement Fund, the excess amount in the Net Settlement Fund shall be distributed pro rata to all Authorized Claimants entitled to receive payment. 80. The Net Settlement Fund will be allocated among all Authorized Claimants whose prorated payment is $10.00 or greater. If the prorated payment to any Authorized Claimant calculates to less than $10.00, it will not be included in the calculation and no distribution will be made to that Authorized Claimant. 81. Settlement Class Members who do not submit acceptable Claim Forms will not share in the distribution of the Net Settlement Fund, however they will nevertheless be bound by the Settlement and the final Judgment of the Court dismissing this Action and related claims. 82. Distributions will be made to Authorized Claimants after all claims have been processed and after the Court has finally approved the Settlement and the Settlement has reached its Effective Date. If there is any balance remaining in the Net Settlement Fund (whether by reason of tax refunds, uncashed checks or otherwise) after at least six (6) months from the date of initial distribution of the Net Settlement Fund, Lead Counsel shall, if feasible and economical after payment of Notice and Administration Expenses, Taxes, and outstanding attorneys’ fees and expenses, redistribute such balance among Authorized Claimants who have cashed their checks in an equitable and economic fashion. These redistributions shall be repeated until the balance in the Net Settlement Fund is no longer feasible and economical to distribute. Any balance that still remains in the Net Settlement Fund after re-distribution(s), which is not feasible or economical to reallocate, after payment of Notice and Administration Expenses, Taxes, and any unpaid attorneys’ fees and expenses, shall be contributed to the Consumer Federation of America, a non-profit, non-sectarian organization, or such other organization designated by Lead Plaintiffs and approved by the Court. 83. Payment pursuant to the Plan of Allocation, or such other plan as may be approved by the Court, shall be conclusive against all Claimants.
