Notice of Proposed Class Action Settlement Howard v. Laboratory Corp. of Am., Case No. 1:23-cv-758-WO-JEP (M.D.N.C.). A federal court authorized this notice. This is not a solicitation from a lawyer. • A proposed class action settlement has been reached in a lawsuit called Howard v. Laboratory Corp. of America, Case No. 1:23-cv-758-WO-JEP, pending in the Middle District of North Carolina. The proposed settlement, if approved, would resolve the case and provide benefits to Settlement Class Members. • The lawsuit alleges that defendants Laboratory Corporation of America and Laboratory Corporation of America Holdings (together “Labcorp”) violated California and Pennsylvania wiretapping laws by facilitating, through third-party tracking technologies, the interception of personally identifiable information and searches that users conducted on Labcorp’s website. Labcorp denies these and all other allegations of wrongdoing and liability, and denies all claims asserted against it. The Court has not determined who is right or wrong. • The settlement, if approved, would resolve the case and require Labcorp to implement certain business practices regarding the use of tracking technologies on its website, summarized below. The settlement does not provide monetary compensation to Settlement Class Members, and Settlement Class Members do not release any claims for damages or other monetary relief. • Generally, you are a member of the Settlement Class if you live in California or Pennsylvania and conducted search queries on Labcorp’s website (www.labcorp.com or any subpages on this website) from May 1, 2021 to April 1, 2026. If you are a member of the Settlement Class, your legal rights will be affected. Please read this notice carefully. The complete terms of the proposed settlement (including definitions for capitalized terms appearing in this notice) are set forth in the Settlement Agreement, which is available at www.LaboratoryCorporationWebsiteSettlement.com. BASIC INFORMATION 1. Why was this notice issued? A federal court authorized this notice to inform you of a proposed class action settlement. This notice explains the litigation, the proposed settlement, and your legal rights. It’s important that you read this notice carefully because your rights will be affected by this settlement. 2. What is a class action settlement? In a class action, one or more people called class representatives sue on behalf of people who have similar claims. All these people are called class members. A class action settlement is an agreement to resolve a lawsuit that applies to all the class members, not just the people who filed the lawsuit. A class action settlement is only legally effective if a court approves it as fair, reasonable, and adequate. Questions?

The Court has preliminarily approved that settlement and authorized this notice to inform you of your rights. The Court will hold a hearing on December 14, 2026 at 10:00 A.M. to decide whether to grant final approval to the settlement. 3. What is this lawsuit about? Plaintiffs allege that Labcorp violated California and Pennsylvania wiretapping laws by facilitating, through third-party tracking technologies, the interception of personally identifiable information and searches that users conducted on Labcorp’s website. Labcorp denies these and all other allegations of wrongdoing and liability, and denies all claims asserted against it. The Court has not decided who is right or wrong. Plaintiffs and Labcorp have now agreed to a settlement to resolve this lawsuit, as described below. By agreeing to the settlement, Labcorp has not admitted that it is liable or that there is any merit to the allegations and claims made in this case. Instead, the proposed settlement, if finally approved, will resolve the lawsuit without deciding who is right or wrong. This lawsuit is called Howard v. Laboratory Corp. of America, Case No. 1:23-cv-758-WO-JEP. The United States District Court for the Middle District of North Carolina is overseeing this lawsuit. WHO IS IN THE SETTLEMENT 4.

What am I giving up in exchange for the settlement benefits?

Among other things, the Settlement Agreement describes the claims you are releasing (called the “Released Claims”). YOUR RIGHTS AND OPTIONS 8. Can I opt-out or exclude myself from the settlement? No. Because the plaintiffs are seeking only injunctive relief (e.g., business practice terms) and because Labcorp is only agreeing to injunctive relief, Settlement Class Members cannot opt out of the settlement. This means that all members of the Settlement Class will be bound by the settlement, if the Court approves it. Questions?

You cannot ask the Court to order a different settlement; the Court can only approve or reject the settlement.
