UNITED STATES DISTRICT COURT EASTERN DISTRICT OF TENNESSEE AT CHATTANOOGA

STEPHEN CAHILL, et al., ) individually and on behalf of all others ) similarly situated ) ) Case No.: 1:23-cv-168 Plaintiffs, ) ) Judge Curtis L. Collier v. ) Magistrate Judge Christopher H. Steger ) MEMORIAL HEART INSTITUTE, LLC ) d/b/a The Chattanooga Heart Institute ) ) Defendant. )

M E M O R A N D U M Before the Court is a motion by Plaintiffs Stephen Cahill, Sheila Edwards, Sidney Jackson, Gisele Reed Allen, Jeff Bryden, and Elyn Painter (collectively “Plaintiffs”) for an order preliminarily approving the Rule 23 settlement agreement in this action. (Doc. 66.) Plaintiffs also request that the Court appoint Plaintiffs as class representatives, appoint Plaintiffs’ counsel as class counsel, order the class notice be distributed to the settlement class, and schedule a final approval hearing. (Doc. 67 at 2–3.) Defendant Memorial Heart Institute, LLC does not oppose the motion. (See Doc. 67-1.) I. BACKGROUND

This action arises from a data breach occurring between March 8, 2023, and March 16, 2023. (Doc. 67 at 2.) Defendant discovered the breach on approximately April 17, 2023. (Doc. 24 ¶ 9.) After discovering the breach, Defendant sent notice of the breach to approximately 460,000 individuals whose private information was accessed or potentially accessed. (Doc 67 at 3.) Of those 460,000 individuals, a subset of 287,000 individuals also potentially had their Social Security numbers compromised. (Id.) Following the data breach, Karakurt, a financially motivated cybercrime group that steals data and demands payments from individuals by threatening disclosure of their personal information, claimed responsibility for the data breach. (Doc. 24 ¶ 14.) Plaintiff Stephen Cahill filed a complaint on behalf of himself and others similarly situated.

(Doc. 1; Doc. 67 at 3.) Soon after, several other individuals filed complaints with similar allegations and the related cases were consolidated. (Id.) On November 2, 2023, Plaintiffs filed a consolidated class action complaint (“CAC”). (Doc. 24.) The complaint stated, among other allegations, that Defendant maintained Plaintiffs’ private information in a reckless manner, failed to take preventative measures to safeguard patient private information, and failed to provide timely and adequate notice to Plaintiffs and other class members. (Id. at 4.) While discovery was ongoing, the parties underwent a full-day virtual mediation on September 9, 2025, in which the parties “reached an agreement in principle to the material terms of a class-wide settlement.” (Doc. 67 at 4.) The settlement creates two classes: the “Total Class” and the “SSN Class.” (Doc. 67 at 5.)

The Total Class is “all living individuals in the United States whose Private Information was identified as accessed or accessible in the Data Incident,” and consists of approximately 460,000 members. (Id.) The SSN Class is a subset of the Total Class and is defined as “all living individuals in the United States who are members of the Total Class and whose Social Security number was identified as accessed or accessible during the Data Incident.” (Id.) The agreement also creates two funds: the Total Class Fund, which is a claims made fund that benefits the entire settlement class including the SSN class, and the SSN Class fund, which is a non-reversionary common fund for the benefit of those whose social security numbers were potentially compromised. (Id. at 6.) Defendant agrees to pay $2,000,000 into the non-reversionary SSN class fund. (Id.) Following the payment of costs and fees, this fund will provide members of the SSN Class the ability to seek a prorated cash payment. (Id.) Defendant also agrees to pay a claims-made settlement fund of up to $1,750,000 into the Total Class Fund. (Id.) This will be used to pay

claims for up to $5,500 per Settlement Class member and two years of medical monitoring from CyEx on a claims-made basis. (Id.) The parties agree that Kroll Settlement Administration should serve as the settlement administrator. (Id.) Defendant will provide Kroll with a list of class members, and Kroll will establish a settlement website to provide class members with all relevant information and send notices to each settlement class member. (Id. at 6–7.) Should a member wish to opt out of the settlement or object to the settlement, they have 60 days to mail such an opt-out or objection. (Id. at 7.) The parties now move the Court for preliminary approval of the settlement agreement. Defendant does not oppose the motion. (See id. at 26–27.) The Court will first address whether

the settlement agreement should be preliminarily approved. The Court will then address the proposed class notice, as well as the proposed class appointments. II. DISCUSSION The parties seek preliminary approval of the settlement agreement under Rule 23 of the Federal Rules of Civil Procedure. Approval of a Rule 23 class-action settlement occurs in three steps: “(1) the court must preliminarily approve the settlement; (2) the class members must be given notice of the proposed settlement; and (3) the court must hold a hearing to determine whether the proposed settlement is fair, reasonable and adequate.” Thacker v. Chesapeake Appalachia, L.L.C., 259 F.R.D. 262, 270 (E.D. Ky. 2009) (citing Tenn. Ass’n of Health Maint. Orgs., Inc. v. Grier, 262 F.3d 559, 565–66 (6th Cir. 2001)). A. Rule 23 Preliminary Approval of Settlement At the preliminary approval stage, the Court must determine whether it “will likely be able

to: (i) approve the proposal under Rule 23(e)(2); and (ii) certify the class for purposes of judgment on the proposal.” Fed. R. Civ. P. 23(e)(1)(B). At this stage, “the questions are simpler, and the court is not expected to, and probably should not, engage in analysis as rigorous as is appropriate for final approval.” Lott v. Louisville Metro Gov’t, No. 3:19-cv-271, 2023 WL 2562407, at *1 (W.D. Ky. Mar. 17, 2023) (quoting Spine & Sports Chiropractic, Inc. v. ZirMed, Inc., No. 3:13- cv-00489, 2015 WL 1976398, at *1 (W.D. Ky. May 4, 2015)). The Court will address both requirements. 1. Likelihood of Approval To preliminarily approve the settlement agreement under Rule 23(e)(2), the proposed settlement must be fair, reasonable, and adequate. To determine this, the Court considers whether:

(A) the class representatives and class counsel have adequately represented the class;

(B) the proposal was negotiated at arm’s length;

(C) the relief provided for the class is adequate, taking into account:

(i) the costs, risks, and delay of trial and appeal;

(ii) the effectiveness of any proposed method of distributing relief to the class, including the method of processing class-member claims;

(iii) the terms of any proposed award of attorney’s fees, including timing of payment; and

(iv) any agreement required to be identified under Rule 23(e)(3); and

(D) the proposal treats class members equitably relative to each other. Fed. R. Civ. P. 23(e)(2)(A)–(D). “The first two factors are procedural in nature, while the latter two direct the Court to examine the substance of the settlement.” In re OnePoint Patient Care LLC, Data Breach Litigation, No. 3:24-cv-649, 2026 WL 74403, at *3 (W.D. Ky. Jan. 9, 2026).
