LABCORP HOLDINGS INC. AND SUBSIDIARIES
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(dollars and shares in millions, except per share data)

1.    BASIS OF FINANCIAL STATEMENT PRESENTATION
Labcorp® Holdings Inc. (Labcorp® or the Company) is a global leader of innovative and comprehensive laboratory services that provides vital information to help doctors, hospitals, pharmaceutical companies, researchers, and patients make clear and confident decisions. By leveraging its unparalleled diagnostics and drug development capabilities, the Company provides insights and accelerates innovations to improve health and improve lives.
On April 25, 2024, the Company announced plans to implement a new public holding company structure, with Labcorp Holdings Inc. as the new holding company. On May 17, 2024, the Company completed the holding company reorganization (Reorganization) and Labcorp Holdings Inc. became the successor issuer to Laboratory Corporation of America Holdings (LCAH). The new holding company has no independent assets or operations and its sole ownership interest is in LCAH.
The Company reports its business in two segments, Diagnostics Laboratories (Dx) and Biopharma Laboratory Services (BLS), formerly Drug Development. For further financial information about these segments, see Note 12 (Business Segment Information) to the Condensed Consolidated Financial Statements. During the three months ended September 30, 2024, Dx and BLS contributed approximately 78% and 22%, respectively, of revenues to the Company. During the nine months ended September 30, 2024, Dx and BLS contributed approximately 78% and 22%, respectively, of revenues to the Company.
The accompanying condensed consolidated financial statements of the Company are unaudited. In the opinion of management, all adjustments necessary for a fair statement of results of operations, cash flows, and financial position have been made. Except as otherwise disclosed, all such adjustments are of a normal recurring nature. Interim results are not necessarily indicative of results for a full year. The year-end condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by generally accepted accounting principles.
The condensed consolidated financial statements and notes are presented in accordance with the rules and regulations of the Securities and Exchange Commission (SEC) and do not contain certain information included in the Company’s fiscal year 2023 Annual Report on Form 10-K (Annual Report). Therefore, these interim statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report.
The condensed consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries for which it exercises control. Long-term investments in affiliated companies in which the Company exercises significant influence, but which it does not control, are accounted for using the equity method. Investments in which the Company does not exercise significant influence (generally, when the Company has an investment of less than 20.0% and no representation on the investee's board of directors) are accounted for at fair value, or at cost minus impairment adjusted for observable price changes in orderly transactions for an identical or similar investment of the same issuer for those investments that do not have readily determinable fair values. All significant inter-company transactions and accounts have been eliminated. The Company does not have any significant variable interest entities or special purpose entities whose financial results are not included in the condensed consolidated financial statements.
The financial statements of the Company's operating foreign subsidiaries are measured using the local currency as the functional currency. Assets and liabilities are translated at exchange rates as of the balance sheet date. Revenues and expenses are translated at average monthly exchange rates prevailing during the period. Resulting translation adjustments are included in “Accumulated other comprehensive income (loss).”
2.    DISCONTINUED OPERATIONS
On June 30, 2023 (the Distribution Date), Labcorp completed the previously announced separation (the Separation or spin-off) from the Company of Fortrea Holdings Inc. (Fortrea), formerly the Company's Clinical Development and Commercialization Services (CDCS) business, into a separate, publicly-traded company. All historical operating results of Fortrea are presented as Discontinued Operations, net of tax, in the Condensed Consolidated Statements of Operations. The spin-off is expected to be treated as tax-free for the Company and its shareholders for U.S. federal income tax purposes.
The spin-off of Fortrea from Labcorp was achieved through the Company’s pro-rata distribution of 100% of the outstanding shares of Fortrea common stock to holders of record of Labcorp common stock. Each holder of record of Labcorp common stock received one share of Fortrea common stock for every share of Labcorp common stock held at 5:00 p.m., Burlington, North Carolina, time on June 20, 2023, the record date for the distribution.
In June 2023, Fortrea, prior to the Separation and while a subsidiary of the Company, issued $570.0 of 7.500% senior secured notes due 2030 (the Fortrea Notes). The proceeds from the Fortrea Notes were used to fund cash payments of
7

LABCORP HOLDINGS INC. AND SUBSIDIARIES
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(dollars and shares in millions, except per share data)
approximately $1,600.0 to the Company in connection with the Separation. The Company does not guarantee the Fortrea Notes following the Separation. Also in June 2023, Fortrea entered into three floating secured overnight financing rate (SOFR) credit facilities totaling $1,520.0. These are comprised of a $450.0 Revolver maturing June 30, 2028; a $500.0 Term Loan A maturing June 30, 2028; and a $570.0 Term Loan B maturing June 30, 2030.
In connection with the spin-off, the Company entered into several agreements with Fortrea on or prior to the Distribution Date that, among other things, provide a framework for the Company’s relationship with Fortrea after the spin-off, including a separation and distribution agreement, a tax matters agreement, an employee matters agreement, and a transition services agreement. These agreements contain the key provisions relating to the spin-off, including provisions relating to the principal intercompany transactions required to effect the spin-off, the conditions to the spin-off and provisions governing the relationship between Fortrea and the Company after the spin-off. The costs to provide these services are included in operating income but the service fees are included in other income.
Financial Information of Discontinued Operations
Earnings from discontinued operations, net of tax in the Consolidated Statements of Operations reflect the after-tax results of Fortrea's business and Separation-related fees, and do not include any allocation of general corporate overhead expense or interest expense of the Company.

Diluted earnings per share is computed by dividing net earnings including the impact of dilutive adjustments by the weighted average number of common shares outstanding plus potentially dilutive shares, as if they had been issued at the earlier of the date of issuance or the beginning of the period presented. Potentially dilutive common shares result primarily from the Company’s outstanding stock options, restricted stock awards, restricted stock units, and performance share awards.

6.    GOODWILL AND INTANGIBLE ASSETS
The changes in the carrying amount of goodwill for the nine months ended September 30, 2024, were as follows:
DxBLSTotal
Balance as of December 31, 2023$4,813.9 $1,328.6 $6,142.5 
Goodwill acquired during the period349.5  349.5 
Foreign currency impact and other adjustments to goodwill(9.5)(0.1)(9.6)
Balance as of September 30, 2024$5,153.9 $1,328.5 $6,482.4 
The Company assesses goodwill and indefinite-lived intangibles for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The Company recognizes an impairment charge for the amount by which the reporting unit's carrying amount exceeds its fair value.
Although the Company believes that the current assumptions and estimates used in its goodwill analysis are reasonable, supportable, and appropriate, the Company's business could be impacted by unfavorable changes, including those that impact the existing assumptions used in the impairment analysis. Various factors could reasonably be expected to unfavorably impact existing assumptions: primarily, a worsening economic environment and protracted economic downturn and related impacts, including delays in revenue from new customers; increases in customer termination activity; or increases in operating costs. Accordingly, there can be no assurance that the estimates and assumptions made for the purposes of the goodwill impairment analysis will prove to be accurate predictions of future performance.
The Company will continue to monitor the financial performance of, and assumptions for, its reporting units. A significant increase in the discount rate, decrease in the revenue and terminal growth rates, decreased operating margin, or substantial reductions in end markets and volume assumptions, could have a negative impact on the estimated fair value of the reporting units. A future impairment charge for goodwill or intangible assets could have a material effect on the Company's consolidated financial position and results of operations.

Credit Facilities
The Company maintains a senior revolving credit facility, which was amended and restated on January 13, 2023. It consists of a five-year facility in the principal amount of up to $1,000.0, with the option of increasing the facility by up to an additional $500.0, subject to the agreement of one or more new or existing lenders to provide such additional amounts and certain other customary conditions. The revolving credit facility also provides for a subfacility of up to $100.0 for swing line borrowings and a subfacility of up to $150.0 for issuances of letters of credit. The Company is required to pay a facility fee on the aggregate commitments under the revolving credit facility, at a per annum rate ranging from 0.10% to 0.225%, depending on the Company's debt ratings. The revolving credit facility is permitted to be used for general corporate purposes, including working capital, capital expenditures, funding of share repurchases and certain other payments, acquisitions, and other investments. The revolving credit facility also provides for the issuance of letters of credit without a reduction of the availability of borrowings

(dollars and shares in millions, except per share data)
under the facility. There was $0.0 outstanding on the Company's current revolving credit facility and $91.9 in outstanding letters of credit on the Company's subfacility as of September 30, 2024. As of September 30, 2024, the effective interest rate on the revolving credit facility was 6.26%. The credit facility expires on April 30, 2026.
Under the revolving credit facility, the Company is subject to negative covenants limiting subsidiary indebtedness and certain other covenants typical for investment grade-rated borrowers, and the Company is required to maintain certain leverage ratios. The Company was in compliance with all covenants in the revolving credit facility at September 30, 2024, and expects that it will remain in compliance with its existing debt covenants for the next twelve months.
On August 23, 2024, the Company and a bankruptcy-remote special purpose vehicle (SPV) entered into an accounts receivable securitization facility (AR Facility) with PNC Bank, National Association (PNC) with a three-year term. The AR Facility allows the Company to borrow from PNC an amount of up to $300.0 through August of 2027 and may increase up to $700.0, subject to the satisfaction of certain conditions.
The SPV is a variable interest entity (VIE) for which the Company is the primary beneficiary. The SPV's sole business consists of the continuous purchase of receivables from the Company which is used as collateral for the loan with PNC. Although the SPV is included in the Company's consolidated financial statements, it is a separate legal entity with separate creditors.
Upon the transfer of ownership and control of the receivables to the SPV, the Company has no retained interests in the receivables sold and they become unavailable to the Company's creditors should the relevant seller become insolvent. The Company has collection and administrative responsibilities for the receivables sold to the SPV.
During the three months ended September 30, 2024, the Company received loan proceeds of $300.0 under the AR Facility, which is included in cash from financing activities in the Condensed Consolidated Statement of Cash Flows.
Senior Notes
On September 23, 2024, LCAH entered into an indenture with U.S. Bank Trust Company, National Association, as trustee (the Trustee) (the Indenture). Also, on September 23, 2024, the Company, LCAH, and the Trustee entered into certain first, second, and third supplemental indentures to the Indenture under each of which LCAH issued, and the Company guaranteed, $650.0 aggregate principal amount of 4.35% Senior Notes due 2030 (the 2030 Notes), $500.0 aggregate principal amount of 4.55% Senior Notes due 2032 (the 2032 Notes) and $850.0 aggregate principal amount of 4.80% Senior Notes due 2034, respectively (the 2034 Notes and, together with the 2030 Notes and the 2032 Notes, the Notes), totaling $2,000.0. Interest on the Notes is payable semi-annually on April 1 and October 1 of each year, commencing April 1, 2025. Net proceeds from the offering of the Notes were approximately $1,982.1 after deducting underwriting discounts and other estimated expenses of the offering. The net proceeds will be used to redeem or repay indebtedness and, to the extent not used for such purpose, for other general corporate purposes. Indebtedness to be redeemed or repaid at or prior to maturity were the Company's 2.30% senior notes due 2024, its 3.60% senior notes due 2025 and $350.0 of borrowings under its revolving credit facility.

9.    COMMITMENTS AND CONTINGENCIES
The Company (and/or its subsidiaries and affiliates) is involved from time to time in various claims and legal actions, including arbitrations, class actions, and other litigation (including those described in more detail below), arising in the ordinary course of business. Some of these actions involve claims that are substantial in amount. These matters include, but are not limited to, intellectual property disputes, commercial and contract disputes, professional liability claims, employee-related matters, transaction-related disputes, securities and corporate law matters, and inquiries, including subpoenas and other civil investigative demands, from governmental agencies, Medicare or Medicaid payers and managed care organizations (MCOs) reviewing billing practices or requesting comment on allegations of billing irregularities that are brought to their attention through billing audits or third parties. The Company receives civil investigative demands or other inquiries from various governmental bodies in the ordinary course of its business. Such inquiries can relate to the Company or other parties, including physicians and other health care providers. The Company works cooperatively to respond to appropriate requests for information.
The Company also is named from time to time in suits brought under the qui tam provisions of the False Claims Act and comparable state laws. These suits typically allege that the Company has made false statements and/or certifications in connection with claims for payment from U.S. federal or state healthcare programs. The suits may remain under seal (hence, unknown to the Company) for some time while the government decides whether to intervene on behalf of the qui tam plaintiff. Such claims are an inevitable part of doing business in the healthcare field today.
The Company believes that it is in compliance in all material respects with all statutes, regulations, and other requirements applicable to its commercial laboratory operations and biopharma laboratory services. These industries are, however, subject to extensive regulation, and the courts have not interpreted many of the applicable statutes and regulations. Therefore, the applicable statutes and regulations could be interpreted or applied by a prosecutorial, regulatory, or judicial authority in a manner that would adversely affect the Company. Potential sanctions for violation of these statutes and regulations include significant civil and criminal penalties, fines, the loss of various licenses, certificates and authorizations, additional liabilities from third-party claims, and/or exclusion from participation in government programs.
Many of the current claims and legal actions against the Company are in preliminary stages, and many of these cases seek an indeterminate amount of damages. The Company records an aggregate legal reserve, which is determined using calculations based on historical loss rates and assessment of trends experienced in settlements and defense costs. In accordance with FASB Accounting Standards Codification Topic 450 “Contingencies,” the Company establishes reserves for judicial, regulatory, and arbitration matters outside the aggregate legal reserve if and when those matters present loss contingencies that are both
15

LABCORP HOLDINGS INC. AND SUBSIDIARIES
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(dollars and shares in millions, except per share data)
probable and reasonably estimable. When loss contingencies are not both probable and reasonably estimable, the Company does not establish separate reserves.
The Company is unable to estimate a range of reasonably probable loss for the proceedings described in more detail below in which damages either have not been specified or, in the Company's judgment, are unsupported and/or exaggerated and (i) the proceedings are in early stages, (ii) there is uncertainty as to the outcome of pending appeals or motions, (iii) there are significant factual issues to be resolved, and/or (iv) there are novel legal issues to be presented. For these proceedings, however, the Company does not believe, based on currently available information, that the adverse outcomes are probable and reasonably estimable, and it does not believe they will have a material adverse effect on the Company's financial statements.
The Company has received various subpoenas and other civil investigative demands related to Medicaid billing. In October 2013, the Company received a Civil Investigative Demand from the State of Texas Office of the Attorney General requesting documents related to its billing to Texas Medicaid. The Company cooperated with this request. On October 5, 2018, the Company received a second Civil Investigative Demand from the State of Texas Office of the Attorney General requesting documents related to its billing to Texas Medicaid. The Company cooperated with this request. On January 26, 2021, the Company was notified that a qui tam Petition was pending under seal in the District Court, 250th Judicial District, Travis County, Texas, and that the State of Texas had intervened. On April 14, 2021, the Petition was unsealed. The Petition alleges that the Company submitted claims for reimbursement to Texas Medicaid that were higher than permitted under Texas Medicaid’s alleged “best price” regulations, and that the Company offered remuneration to Texas health care providers in the form of discounted pricing for certain laboratory testing services in exchange for the providers’ referral of Texas Medicaid business to the Company. The Petition seeks actual and double damages and civil penalties, as well as recovery of costs, attorney's fees, and legal expenses. On August 1, 2022, the District Court entered an order granting the Company's Motion for Partial Summary Judgment with respect to the claim that the Company submitted claims for reimbursement to Texas Medicaid that were higher than permitted under Texas Medicaid's alleged “best price” regulations. Plaintiffs filed a Notice of Non-Suit and Motion for Entry of Final Judgment and, on November 11, 2022, the court entered a Judgment. Plaintiffs filed a Notice of Appeal with respect to the court's order granting the Company's Motion for Partial Summary Judgment, referenced above. The Company will vigorously defend the lawsuit.
On August 31, 2015, the Company was served with a putative class action lawsuit, Patty Davis v. Laboratory Corporation of America, et al., filed in the Circuit Court of the Thirteenth Judicial Circuit for Hillsborough County, Florida. The complaint alleges that the Company violated the Florida Consumer Collection Practices Act by billing patients who were collecting benefits under the Workers' Compensation Statutes. The lawsuit seeks injunctive relief and actual and statutory damages, as well as recovery of attorney's fees and legal expenses. In April 2017, the Circuit Court granted the Company’s Motion for Judgment on the Pleadings. The Plaintiff appealed the Circuit Court’s ruling to the Florida Second District Court of Appeal. On October 16, 2019, the Florida Second District Court of Appeal reversed the Circuit Court’s dismissal, but certified a controlling issue of Florida law to the Florida Supreme Court. On February 17, 2020, the Florida Supreme Court accepted jurisdiction of the lawsuit. The court held oral arguments on December 9, 2020. On May 26, 2022, the Florida Supreme Court issued an opinion approving the result of the Florida Second District Court of Appeal in favor of the Plaintiff. The Company will vigorously defend the lawsuit.
On December 29, 2021, the Company was served with a putative class action lawsuit, Nathaniel J. Nolan, et al. v. Laboratory Corporation of America Holdings, filed in the U.S. District Court for the Middle District of North Carolina. The complaint alleges that the Company's patient acknowledgement of estimated financial responsibility form is misleading. The lawsuit seeks a declaratory judgment under the consumer protection laws of Nevada and Florida that the form is materially misleading and deceptive, an injunction barring the use of the form, damages on behalf of an alleged class, and attorney's fees and expenses. On February 28, 2022, the Company filed a Motion to Dismiss all claims. On February 13, 2023, the court entered an order granting the Company's Motion to Dismiss. On March 13, 2023, Plaintiffs filed a Notice of Appeal. On April 10, 2024, the U.S. Court of Appeals for the Fourth Circuit issued an order affirming in part, reversing in part, and remanding the case to the District Court for further proceedings. The Company will vigorously defend the lawsuit.
On April 1, 2019, Covance Research Products was served with a Grand Jury Subpoena issued by the Department of Justice (DOJ) in Miami, Florida requiring the production of documents related to the importation into the United States of live non-human primate shipments originating from or transiting through China, Cambodia, and/or Vietnam from April 1, 2014 through March 28, 2019. The Company is cooperating with the DOJ.
On May 14, 2019, Retrieval-Masters Creditors Bureau, Inc. d/b/a American Medical Collection Agency (AMCA), an external collection agency, notified the Company about a security incident AMCA experienced that may have involved certain personal information about some of the Company’s patients (the AMCA Incident). The Company referred patient balances to
16

LABCORP HOLDINGS INC. AND SUBSIDIARIES
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(dollars and shares in millions, except per share data)
AMCA only when direct collection efforts were unsuccessful. The Company’s systems were not impacted by the AMCA Incident. Upon learning of the AMCA Incident, the Company promptly stopped sending new collection requests to AMCA and stopped AMCA from continuing to work on any pending collection requests from the Company. AMCA informed the Company that it appeared that an unauthorized user had access to AMCA’s system between August 1, 2018, and March 30, 2019, and that AMCA could not rule out the possibility that personal information on AMCA’s system was at risk during that time period. Information on AMCA’s affected system from the Company may have included name, address, and balance information for the patient and person responsible for payment, along with the patient’s phone number, date of birth, referring physician, and date of service. The Company was later informed by AMCA that health insurance information may have been included for some individuals, and because some insurance carriers utilize the Social Security Number as a subscriber identification number, the Social Security Number for some individuals may also have been affected. No ordered tests, laboratory test results, or diagnostic information from the Company were in the AMCA affected system. The Company notified individuals for whom it had a valid mailing address. For the individuals whose Social Security Number was affected, the notice included an offer to enroll in credit monitoring and identity protection services that was provided free of charge for 24 months.
Twenty-three putative class action lawsuits were filed against the Company related to the AMCA Incident in various U.S. District Courts. Numerous similar lawsuits have been filed against other health care providers who used AMCA. These lawsuits were consolidated into a multidistrict litigation in the District of New Jersey. On November 15, 2019, the Plaintiffs filed a Consolidated Class Action Complaint in the U.S. District Court of New Jersey. The consolidated Complaint generally alleged that the Company did not adequately protect its patients’ data and failed to timely notify those patients of the AMCA Incident. The Complaint asserted various causes of action, including but not limited to negligence, breach of implied contract, unjust enrichment, and the violation of state data protection statutes. The Complaint sought damages on behalf of a class of all affected Company customers. On January 22, 2020, the Company filed Motions to Dismiss all claims. On December 16, 2021, the court granted in part and denied in part the Company's Motion to Dismiss. On March 31, 2022, the Plaintiffs filed an Amended Complaint alleging claims for negligence, negligence per se, breach of confidence, invasion of privacy, and various state statutory claims, including a claim under the California Confidentiality of Medical Information Act. The Company filed a Motion to Dismiss certain claims of the Amended Complaint. On May 5, 2023, the court granted in part and denied in part the Company's Motion to Dismiss. The Company will vigorously defend the remaining claims in the multi-district litigation.
The Company was served with a shareholder derivative lawsuit, Raymond Eugenio, Derivatively on Behalf of Nominal Defendant, Laboratory Corporation of America Holdings v. Lance Berberian, et al., filed in the Court of Chancery of the State of Delaware on April 23, 2020. The complaint asserts derivative claims on the Company’s behalf against the Company’s board of directors and certain executive officers. The complaint generally alleges that the defendants failed to ensure that the Company utilized proper cybersecurity safeguards and failed to implement a sufficient response to data security incidents, including the AMCA Incident. The complaint asserts derivative claims for breach of fiduciary duty and seeks relief including damages, certain disclosures, and certain changes to the Company’s internal governance practices. On June 2, 2020, the Company filed a Motion to Stay the lawsuit due to its overlap with the multi-district litigation referenced above. On July 2, 2020, the Company filed a Motion to Dismiss. On July 14, 2020, the court entered an order staying the lawsuit pending the resolution of the multi-district litigation. The Company will vigorously defend the lawsuit.
Certain governmental entities have requested information from the Company related to the AMCA Incident. The Company received a request for information from the Office for Civil Rights (OCR) of the Department of Health and Human Services. On April 28, 2020, OCR notified the Company of the closure of its inquiry. The Company has also received requests from a multi-state group of state Attorneys General and is cooperating with these requests for information.
On January 31, 2020, the Company was served with a putative class action lawsuit, Luke Davis and Julian Vargas, et al. v. Laboratory Corporation of America Holdings, filed in the U.S. District Court for the Central District of California. The lawsuit alleges that visually impaired patients are unable to use the Company's touchscreen kiosks at Company patient service centers in violation of the Americans with Disabilities Act and similar California statutes. The lawsuit seeks statutory damages, injunctive relief, and attorney's fees and costs. On March 20, 2020, the Company filed a Motion to Dismiss Plaintiffs' Complaint and to Strike Class Allegations. In August 2020, the Plaintiffs filed an Amended Complaint. On April 26, 2021, the Plaintiffs and the Company each filed Motions for Summary Judgment and the Plaintiffs filed a Motion for Class Certification. On May 23, 2022, the court entered an order granting Plaintiffs’ Motion for Class Certification. On June 6, 2022, the Company filed a Petition for Permission to Appeal the Order Granting Class Certification with the U.S. Court of Appeals for the Ninth Circuit. On September 22, 2022, the Ninth Circuit granted the Company's Petition for Permission to Appeal the Order Granting Class Certification. On February 8, 2024, the Ninth Circuit affirmed the trial court’s decision to certify both a California damages class and a nationwide injunctive class. On March 25, 2024, the Company filed a Petition for Rehearing En Banc with the Ninth Circuit. On April 18, 2024, the Ninth Circuit denied the Petition for Rehearing En Banc. On September 13, 2024, the

Company filed a Petition for Writ of Certiorari with the United States Supreme Court. The Company will vigorously defend the lawsuit.
On October 16, 2020, Ravgen Inc. filed a patent infringement lawsuit, Ravgen Inc. v. Laboratory Corporation of America Holdings, in the U.S. District Court for the Western District of Texas, alleging infringement of two Ravgen-owned U.S. patents. The lawsuit seeks monetary damages, enhancement of those damages for willfulness, and recovery of attorney’s fees and costs. On September 28, 2022, a jury rendered a verdict in favor of the Plaintiff on the remaining patent at issue, finding that the Company willfully infringed Ravgen's patent, and awarded damages of $272.0. Plaintiff filed post-trial motions seeking enhanced damages of up to $817.0 based on the finding of willfulness, as well as attorney's fees and costs. On May 12, 2023, the court issued an order granting Plaintiff's motion in part and awarding enhanced damages of $100.0. The Company strongly disagrees with the verdict, based on a number of legal factors, and will vigorously defend the lawsuit through the appeal process. On June 4, 2021, the Company also instituted proceedings before the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office challenging the validity of the Ravgen patent at issue in the trial. In November 2022, the Patent Trial and Appeal Board issued a decision upholding the validity of the Ravgen patent, and the Company has filed an appeal of this decision.
On May 14, 2020, the Company was served with a putative class action lawsuit, Jose Bermejo v. Laboratory Corporation of America (Bermejo I) filed in the Superior Court of California, County of Los Angeles Central District, alleging that certain non-exempt California-based employees were not properly compensated for driving time or properly paid wages upon termination of employment. The Plaintiff asserts these actions violate various California Labor Code provisions and Section 17200 of the Business and Professional Code. The lawsuit seeks monetary damages, civil penalties, and recovery of attorney’s fees and costs. On June 15, 2020, the lawsuit was removed to the U.S. District Court for the Central District of California. On June 16, 2020, the Company was served with a Private Attorney General Act lawsuit by the same plaintiff in Jose Bermejo v.

The Company has a noncontrolling interest put related to its Ontario subsidiary that has been classified as mezzanine equity in the Company’s condensed consolidated balance sheets. The noncontrolling interest put is valued at its contractually determined value, which approximates fair value.
The Company offers certain employees the opportunity to participate in an employee-funded deferred compensation plan (DCP). A participant's deferrals are allocated by the participant to one or more of multiple measurement funds, which are indexed to externally managed funds. From time to time, to offset the cost of the growth in the participant's investment accounts, the Company purchases life insurance policies, with the Company named as beneficiary of the policies. Changes in the cash surrender value of the life insurance policies are based upon earnings and changes in the value of the underlying investments, which are typically invested in a similar manner to the participant's allocations. Changes in the fair value of the DCP obligation are derived using quoted prices in active markets based on the market price per unit multiplied by the number of units. The cash surrender value and the DCP obligations are classified within Level 2 because their inputs are derived principally from observable market data by correlation to the hypothetical investments.
Contingent accrued earn-out business acquisition consideration liabilities are measured at fair value using Level 3 valuations. These contingent consideration liabilities were recorded at fair value on the acquisition date and are remeasured quarterly based on the then assessed fair value and adjusted if necessary. The increases or decreases in the fair value of contingent consideration payable can result from changes in anticipated revenue levels and changes in assumed discount periods and rates. As the fair value measure is based on significant inputs that are not observable in the market, they are categorized as Level 3.
The carrying amounts of cash and cash equivalents, accounts receivable, income taxes receivable, and accounts payable are considered to be representative of their respective fair values due to their short-term nature. The fair market value of the senior notes, based on market pricing, was approximately $6,314.0 and $4,850.4 as of September 30, 2024, and December 31, 2023, respectively. The Company's note and debt instruments are classified as Level 2 instruments, as the fair market values of these instruments are determined using other observable inputs.

GENERAL (dollars in millions, except per share data)
Revenues for the nine months ended September 30, 2024, were $9,679.5, an increase of 6.0% from $9,128.3 during the nine months ended September 30, 2023. The increase was due to organic revenue of 3.4%, acquisitions, net of divestitures, of 2.4%, and favorable foreign currency translation of 0.2%. The 3.4% increase in organic revenue was driven by a 4.5% increase in the Company's organic Base Business, partially offset by a 1.1% decrease in COVID-19 PCR testing (COVID-19 Testing). Base Business includes Labcorp's operations except for COVID-19 Testing.
The Company defines organic growth as the increase in revenue excluding the year-over-year impact of acquisitions, divestitures, and currency. Acquisition and divestiture impact is considered for a twelve month period following the close of each transaction.

As permitted under Rule 13-01(a)(4)(vi) of Regulation S-X, we have excluded the summarized financial information for LCAH because the assets, liabilities and results of operations of LCAH are not materially different than the corresponding amounts in the Company’s consolidated financial statements and management believes such summarized financial information would be repetitive and would not provide incremental value to investors.

Foreign Currency Exchange Rates
Approximately 13.6% of the Company’s revenues for the nine months ended September 30, 2024, and approximately 13.7% of the Company’s revenue for the nine months ended September 30, 2023, were denominated in currencies other than the U.S. Dollar (USD). The Company’s financial statements are reported in USD and, accordingly, fluctuations in exchange rates will affect the translation of revenues and expenses denominated in foreign currencies into USD for purposes of reporting the Company’s consolidated financial results. In the third quarter of 2024 and the year ended December 31, 2023, the most significant currency exchange rate exposures were to the Canadian dollar, Swiss Franc, Euro and British Pound. Excluding the
33

impacts from any outstanding or future hedging transactions, a hypothetical change of 10% in average exchange rates used to translate all foreign currencies to USD would have impacted income before income taxes for the nine months ended September 30, 2024, by approximately $20.8. Gross accumulated currency translation adjustments recorded as a separate component of shareholders’ equity were $78.3 and $(56.0) for the quarter ended September 30, 2024 and 2023, respectively. The Company does not have significant operations in countries in which the economy is considered to be highly inflationary.
The Company earns revenue from service contracts over a period of time, ranging from months to years. Accordingly, exchange rate fluctuations during this period may affect the Company’s profitability with respect to such contracts. The Company is also subject to foreign currency transaction risk for fluctuations in exchange rates during the period of time between the consummation and cash settlement of transactions. The Company limits its foreign currency transaction risk through exchange rate fluctuation provisions stated in some of its contracts with customers, or it may hedge transaction risk with foreign currency forward contracts. At September 30, 2024, the Company had 9 open foreign exchange forward contracts with various amounts maturing monthly through October 2024 with a notional value totaling approximately $382.0. At December 31, 2023, the Company had 9 open foreign exchange forward contracts with various amounts maturing monthly through January 2024 with a notional value totaling approximately $305.8.
The Company is party to USD to Swiss Franc cross-currency swap agreements with an aggregate notional amount of $1,200.0, $300.0 maturing in 2029, 300.0 maturing in 2031 and 600.0 maturing in 2034, as a hedge against the impact of foreign exchange movements on its net investment in a Swiss Franc functional currency subsidiary.
Interest Rates
Some of the Company’s debt from time to time is subject to interest at variable rates. As a result, fluctuations in interest rates can affect the business. The Company attempts to manage interest rate risk and overall borrowing costs through an appropriate mix of fixed and variable rate debt including by the utilization of derivative financial instruments, primarily interest rate swaps.
Borrowings under the Company’s term loan credit facility, now repaid, and revolving credit facility are subject to variable interest rates, unless fixed through interest rate swaps or other agreements.
In May 2021, to hedge against changes in the fair value portion of the Company’s long-term debt, the Company entered into fixed-to-variable interest rate swap agreements for the 2.70% senior notes due 2031 with an aggregate notional value of $500.0 and variable interest rates based on three-month SOFR plus 1.0706%.
ITEM 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
As of the end of the period covered by this Quarterly Report on Form 10-Q, the Company carried out, under the supervision and with the participation of the Company’s management, including the Company’s principal executive officer and principal financial officer, an evaluation of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rules13a-15 and 15d-15(e) under the Securities Exchange Act of 1934, as amended). Based upon this evaluation, the Company’s principal executive officer and principal financial officer concluded that the Company’s disclosure controls and procedures were effective as of September 30, 2024.
Changes in Internal Control Over Financial Reporting
There were no changes in the Company’s internal control over financial reporting (as defined in Rules13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended) that occurred during the quarter ended September 30, 2024, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

LABCORP HOLDINGS INC. AND SUBSIDIARIES
PART I - OTHER INFORMATION
Item 1. Legal Proceedings
See Note 9 (Commitments and Contingencies) to the Company’s condensed consolidated financial statements, above, which is incorporated herein by reference.
Item 1A. Risk Factors
The risk factors set forth below revise and supplement the corresponding risk factors set forth in the Company's Annual Report on Form 10-K for the year ended December 31, 2023. With the exception of the following, there have been no material changes in the risk factors that appear in the Company's Annual Report on Form 10-K for the year ended December 31, 2023.
U.S. Food and Drug Administration (FDA) regulation of diagnostic products, increased FDA regulation of laboratory-developed tests (LDTs), and regulation by other countries of diagnostic tests and related products could result in increased costs and the imposition of fines or penalties, and could have a material adverse effect upon the Company’s business.
The FDA has regulatory responsibility for instruments, test kits, reagents and other devices used by clinical laboratories. The FDA enforces laws and regulations that govern the development, testing, manufacturing, performance, labeling, advertising, marketing, distribution, and surveillance of diagnostic products, and it regularly inspects and reviews the manufacturing processes and product performance of diagnostic products. Dx’s point-of-care testing devices are subject to regulation by the FDA.
LDTs developed by high complexity clinical laboratories are currently generally offered as services to health care providers under the CLIA regulatory framework administered by CMS, without the requirement for FDA clearance or approval. However, since the 1990s, the FDA has asserted that it has authority to regulate LDTs as medical devices but has exercised enforcement discretion to refrain from systematic regulation of LDTs. In 2014, the FDA issued draft guidance describing how it intended to discontinue its enforcement discretion policy and begin regulating LDTs as medical devices; however, that draft guidance was not finalized, and the FDA instead continued its enforcement discretion policy and indicated that it intended to work with Congress to enact comprehensive legislative reform of diagnostics oversight. In February 2020, the FDA issued a statement with a table of pharmacogenetic associations setting forth certain gene-drug interactions that the agency determined are supported by the scientific literature to help ensure that claims being made for pharmacogenetic tests are grounded in sound science, thereby reducing the risk of enforcement actions with respect to LDTs offering claims consistent with the table. The FDA noted that it could take enforcement actions under the current medical device framework regarding diagnostic claims the agency determines not to be sufficiently supported. In addition, in 2021, the Verifying Accurate, Leading-edge, IVCT Development (VALID) Act was introduced in Congress and provided a framework to regulate in vitro diagnostics and LDTs as in vitro clinical tests. In 2022, the VALID Act was incorporated into the Senate user fee bill but was not included in the year-end Consolidated Appropriations Act of 2022. On March 29, 2023, the VALID Act was reintroduced and remains pending. On April 29, 2024, the FDA released a final rule purporting to clarify its authority to regulate LDTs as medical devices under the federal Food, Drug, and Cosmetic Act, under which it will phase out its general enforcement discretion approach for LDTs under a four-year period subject to certain continuing enforcement discretion policies. More specifically, among other policies, the final rule provides that the FDA will continue to exercise discretion not to enforce premarket review and most FDA quality system requirements for unmodified LDTs first marketed prior to issuance of the final rule; will continue to exercise discretion not to enforce premarket review requirements for LDTs approved by the State of New York; and will continue to exercise discretion not to enforce premarket review and most FDA quality system requirements for LDTs developed and performed by a laboratory integrated into a health system for unmet needs for patients under the care of the same health system, where no FDA cleared or approved test is available. The final rule was published on May 6, 2024, and in the absence of a successful legal challenge, will become effective on May 6, 2025. On May 29, 2024, the American Clinical Laboratory Association (ACLA) and its member company, HealthTrackRx, filed a lawsuit against the FDA in the United States District Court for the Eastern District of Texas, challenging the FDA's final rule. While the lawsuit may change the final rule or delay or prevent its enforcement, the issuance of the final rule presents an increased risk of FDA enforcement actions for laboratory tests offered by companies without FDA clearance or approval that do not fall within the ongoing enforcement discretion policies. However, the outcome and its ultimate impact on the Company’s business remain difficult to predict at this time.
Current FDA regulation of the Company’s diagnostic products and the potential for future increased regulation of the Company’s LDTs could result in increased costs and administrative and legal actions for noncompliance, including warning letters, fines, penalties, product suspensions, product recalls, injunctions, and other civil and criminal sanctions, and could impair the development and commercialization of new tests, which could have a material adverse effect upon the Company.
35

Regulation of diagnostics products in jurisdictions outside the U.S. in which the Company operates may impact laboratory testing offered by the Company in both Dx and BLS. For example, the European Union In Vitro Diagnostics Regulation (Regulation (EU) 2017/746 (EU IVDR)) established a new legislative framework for in vitro diagnostic devices that are used in certain circumstances, and includes a rule-based classification and quality and safety standards. The EU IVDR, where applicable to BLS's services, could impact BLS's ability to support trials, result in increased costs and administrative and legal actions, and have an adverse effect.
Item 2. Unregistered Sales of Equity Securities and Use of Proceeds (dollars and shares in millions, except per share data)

Labcorp® Holdings Inc. (Labcorp® or the Company) is a global leader of innovative and comprehensive laboratory services that provides vital information to help doctors, hospitals, pharmaceutical companies, researchers, and patients make clear and confident decisions. By leveraging its unparalleled diagnostics and drug development capabilities, the Company provides insights and accelerates innovations to improve health and improve lives.
On April 25, 2024, the Company announced plans to implement a new public holding company structure, with Labcorp Holdings Inc. as the new holding company. On May 17, 2024, the Company completed the holding company reorganization (Reorganization) and Labcorp Holdings Inc. became the successor issuer to Laboratory Corporation of America Holdings (LCAH). The new holding company has no independent assets or operations and its sole ownership interest is in LCAH.
The Company reports its business in two segments, Diagnostics Laboratories (Dx) and Biopharma Laboratory Services (BLS), formerly Drug Development. For further financial information about these segments, see Note 12 (Business Segment Information) to the Condensed Consolidated Financial Statements. During the three months ended September 30, 2024, Dx and BLS contributed approximately 78% and 22%, respectively, of revenues to the Company. During the nine months ended September 30, 2024, Dx and BLS contributed approximately 78% and 22%, respectively, of revenues to the Company.
The accompanying condensed consolidated financial statements of the Company are unaudited. In the opinion of management, all adjustments necessary for a fair statement of results of operations, cash flows, and financial position have been made. Except as otherwise disclosed, all such adjustments are of a normal recurring nature. Interim results are not necessarily indicative of results for a full year. The year-end condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by generally accepted accounting principles.
The condensed consolidated financial statements and notes are presented in accordance with the rules and regulations of the Securities and Exchange Commission (SEC) and do not contain certain information included in the Company’s fiscal year 2023 Annual Report on Form 10-K (Annual Report). Therefore, these interim statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report.
The condensed consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries for which it exercises control. Long-term investments in affiliated companies in which the Company exercises significant influence, but which it does not control, are accounted for using the equity method. Investments in which the Company does not exercise significant influence (generally, when the Company has an investment of less than 20.0% and no representation on the investee's board of directors) are accounted for at fair value, or at cost minus impairment adjusted for observable price changes in orderly transactions for an identical or similar investment of the same issuer for those investments that do not have readily determinable fair values. All significant inter-company transactions and accounts have been eliminated. The Company does not have any significant variable interest entities or special purpose entities whose financial results are not included in the condensed consolidated financial statements.
The financial statements of the Company's operating foreign subsidiaries are measured using the local currency as the functional currency. Assets and liabilities are translated at exchange rates as of the balance sheet date. Revenues and expenses are translated at average monthly exchange rates prevailing during the period. Resulting translation adjustments are included in “Accumulated other comprehensive income (loss).”

Earnings Per Share [Abstract]  
Earnings Per Share EARNINGS PER SHARE
Basic earnings per share is computed by dividing net earnings attributable to the Company by the weighted average number of shares of the Company's common stock outstanding. Diluted earnings per share is computed by dividing net earnings including the impact of dilutive adjustments by the weighted average number of common shares outstanding plus potentially dilutive shares, as if they had been issued at the earlier of the date of issuance or the beginning of the period presented. Potentially dilutive common shares result primarily from the Company’s outstanding stock options, restricted stock awards, restricted stock units, and performance share awards.
The following represents a reconciliation of basic earnings per share to diluted earnings per share for the three and nine months ended September 30:

The Company has a noncontrolling interest put related to its Ontario subsidiary that has been classified as mezzanine equity in the Company’s condensed consolidated balance sheets. The noncontrolling interest put is valued at its contractually determined value, which approximates fair value.
The Company offers certain employees the opportunity to participate in an employee-funded deferred compensation plan (DCP). A participant's deferrals are allocated by the participant to one or more of multiple measurement funds, which are indexed to externally managed funds. From time to time, to offset the cost of the growth in the participant's investment accounts, the Company purchases life insurance policies, with the Company named as beneficiary of the policies. Changes in the cash surrender value of the life insurance policies are based upon earnings and changes in the value of the underlying investments, which are typically invested in a similar manner to the participant's allocations. Changes in the fair value of the DCP obligation are derived using quoted prices in active markets based on the market price per unit multiplied by the number of units. The cash surrender value and the DCP obligations are classified within Level 2 because their inputs are derived principally from observable market data by correlation to the hypothetical investments.
Contingent accrued earn-out business acquisition consideration liabilities are measured at fair value using Level 3 valuations. These contingent consideration liabilities were recorded at fair value on the acquisition date and are remeasured quarterly based on the then assessed fair value and adjusted if necessary. The increases or decreases in the fair value of contingent consideration payable can result from changes in anticipated revenue levels and changes in assumed discount periods and rates. As the fair value measure is based on significant inputs that are not observable in the market, they are categorized as Level 3.
The carrying amounts of cash and cash equivalents, accounts receivable, income taxes receivable, and accounts payable are considered to be representative of their respective fair values due to their short-term nature. The fair market value of the senior notes, based on market pricing, was approximately $6,314.0 and $4,850.4 as of September 30, 2024, and December 31, 2023, respectively. The Company's note and debt instruments are classified as Level 2 instruments, as the fair market values of these instruments are determined using other observable inputs.

Segment Reporting Disclosure [Text Block] BUSINESS SEGMENT INFORMATION
The following table is a summary of segment information for the three and nine months ended September 30, 2024, and 2023. The “management approach” has been used to present the following segment information. This approach is based upon the way the management of the Company organizes segments within an enterprise for making operating decisions and assessing performance. Financial information is reported on the basis that it is used internally by the chief operating decision maker (CODM) for evaluating segment performance and deciding how to allocate resources to segments. The Company’s chief executive officer has been identified as the CODM.
Segment asset information is not presented because it is not used by the CODM at the segment level. The Corporate costs not allocated to segments include the costs of centralized functions, other charges such as acquisition expenses, spin-off costs, remaining unallocated costs of the CDCS business, and COVID-19 related costs unrelated to the segment. Centralized functions include corporate governance, executive management and related human resources, finance, legal, risk management, and information technology functions.

2.    DISCONTINUED OPERATIONS
On June 30, 2023 (the Distribution Date), Labcorp completed the previously announced separation (the Separation or spin-off) from the Company of Fortrea Holdings Inc. (Fortrea), formerly the Company's Clinical Development and Commercialization Services (CDCS) business, into a separate, publicly-traded company. All historical operating results of Fortrea are presented as Discontinued Operations, net of tax, in the Condensed Consolidated Statements of Operations. The spin-off is expected to be treated as tax-free for the Company and its shareholders for U.S. federal income tax purposes.
The spin-off of Fortrea from Labcorp was achieved through the Company’s pro-rata distribution of 100% of the outstanding shares of Fortrea common stock to holders of record of Labcorp common stock. Each holder of record of Labcorp common stock received one share of Fortrea common stock for every share of Labcorp common stock held at 5:00 p.m., Burlington, North Carolina, time on June 20, 2023, the record date for the distribution.
In June 2023, Fortrea, prior to the Separation and while a subsidiary of the Company, issued $570.0 of 7.500% senior secured notes due 2030 (the Fortrea Notes). The proceeds from the Fortrea Notes were used to fund cash payments of
approximately $1,600.0 to the Company in connection with the Separation. The Company does not guarantee the Fortrea Notes following the Separation. Also in June 2023, Fortrea entered into three floating secured overnight financing rate (SOFR) credit facilities totaling $1,520.0. These are comprised of a $450.0 Revolver maturing June 30, 2028; a $500.0 Term Loan A maturing June 30, 2028; and a $570.0 Term Loan B maturing June 30, 2030.
In connection with the spin-off, the Company entered into several agreements with Fortrea on or prior to the Distribution Date that, among other things, provide a framework for the Company’s relationship with Fortrea after the spin-off, including a separation and distribution agreement, a tax matters agreement, an employee matters agreement, and a transition services agreement. These agreements contain the key provisions relating to the spin-off, including provisions relating to the principal intercompany transactions required to effect the spin-off, the conditions to the spin-off and provisions governing the relationship between Fortrea and the Company after the spin-off. The costs to provide these services are included in operating income but the service fees are included in other income.
Financial Information of Discontinued Operations
Earnings from discontinued operations, net of tax in the Consolidated Statements of Operations reflect the after-tax results of Fortrea's business and Separation-related fees, and do not include any allocation of general corporate overhead expense or interest expense of the Company.

The changes in the carrying amount of goodwill for the nine months ended September 30, 2024, were as follows:
DxBLSTotal

The Company assesses goodwill and indefinite-lived intangibles for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The Company recognizes an impairment charge for the amount by which the reporting unit's carrying amount exceeds its fair value.
Although the Company believes that the current assumptions and estimates used in its goodwill analysis are reasonable, supportable, and appropriate, the Company's business could be impacted by unfavorable changes, including those that impact the existing assumptions used in the impairment analysis. Various factors could reasonably be expected to unfavorably impact existing assumptions: primarily, a worsening economic environment and protracted economic downturn and related impacts, including delays in revenue from new customers; increases in customer termination activity; or increases in operating costs. Accordingly, there can be no assurance that the estimates and assumptions made for the purposes of the goodwill impairment analysis will prove to be accurate predictions of future performance.
The Company will continue to monitor the financial performance of, and assumptions for, its reporting units. A significant increase in the discount rate, decrease in the revenue and terminal growth rates, decreased operating margin, or substantial reductions in end markets and volume assumptions, could have a negative impact on the estimated fair value of the reporting units. A future impairment charge for goodwill or intangible assets could have a material effect on the Company's consolidated financial position and results of operations.

The Company assesses goodwill and indefinite-lived intangibles for impairment at least annually or whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The Company recognizes an impairment charge for the amount by which the reporting unit's carrying amount exceeds its fair value.
Although the Company believes that the current assumptions and estimates used in its goodwill analysis are reasonable, supportable, and appropriate, the Company's business could be impacted by unfavorable changes, including those that impact the existing assumptions used in the impairment analysis. Various factors could reasonably be expected to unfavorably impact existing assumptions: primarily, a worsening economic environment and protracted economic downturn and related impacts, including delays in revenue from new customers; increases in customer termination activity; or increases in operating costs. Accordingly, there can be no assurance that the estimates and assumptions made for the purposes of the goodwill impairment analysis will prove to be accurate predictions of future performance.
The Company will continue to monitor the financial performance of, and assumptions for, its reporting units. A significant increase in the discount rate, decrease in the revenue and terminal growth rates, decreased operating margin, or substantial reductions in end markets and volume assumptions, could have a negative impact on the estimated fair value of the reporting units. A future impairment charge for goodwill or intangible assets could have a material effect on the Company's consolidated financial position and results of operations.
