NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(dollars and shares in millions, except per share data)

1.    BASIS OF FINANCIAL STATEMENT PRESENTATION

Laboratory Corporation of America® Holdings (Labcorp® or the Company) is a leading global life sciences company that provides vital information to help doctors, hospitals, pharmaceutical companies, researchers, and patients make clear and confident decisions. By leveraging its strong diagnostics and drug development capabilities, the Company provides insights and accelerates innovations to improve health and improve lives.

The Company reports its business in two segments, Labcorp Diagnostics (Dx) and Labcorp Drug Development (DD). For further financial information about these segments, see Note 11 (Business Segment Information) to the Condensed Consolidated Financial Statements. During the three months ended September 30, 2022, Dx and DD contributed approximately 61% and 39%, respectively, of revenues to the Company. During the nine months ended September 30, 2022, Dx and DD contributed approximately 61% and 39%, respectively, of revenues to the Company.

On July 28, 2022, the Company announced that its board of directors authorized the Company to pursue a spin-off of its wholly owned Clinical Development business, which includes parts of its DD segment focused on providing Phase I-IV clinical trial management, market access, and technology solutions to pharmaceutical and biotechnology organizations. The planned spin-off will result in two independent, publicly traded companies. The spin-off is intended to be a tax-free transaction to the Company and its stockholders for United States (U.S.) federal income tax purposes and is expected to be effected through a dividend of the Clinical Development business’ shares to the Company's shareholders. The Company anticipates that, consistent with any applicable legal and tax requirements, there will be ongoing transitional and commercial arrangements to provide for a seamless delivery of services to the customers and other stakeholders of the independent companies following the spin-off. The Company is targeting completion of the spin-off with an accelerated timeframe of mid-2023. The spin-off will be subject to the satisfaction of certain customary conditions, including, among others, the receipt of final approval by the Company's board of directors, the receipt of appropriate assurances regarding the tax-free nature of the separation, and the effectiveness of any required filings with the U.S. Securities and Exchange Commission (SEC).

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).”

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 SEC and do not contain certain information included in the Company’s fiscal year 2021 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.

Recently Adopted Accounting Guidance

In October 2021, the Financial Accounting Standards Board (FASB) issued a new accounting standard, Accounting Standards Update 2021-08, to improve the accounting for acquired revenue contracts with customers in a business combination. The Company early adopted this standard effective January 1, 2022. The adoption of this standard did not have a material impact on the consolidated financial statements.

Within DD, revenues of $6.6 and $10.1 were recognized during the three months ended September 30, 2022 and 2021, respectively, and revenues of $75.8 and $38.9 were recognized during the nine months ended September 30, 2022 and 2021, respectively, from performance obligations that were satisfied in previous periods. This revenue primarily relates to adjustments related to changes in scope in full service clinical studies, and to a lesser extent, changes in estimates.

`3.    BUSINESS ACQUISITIONS

During the nine months ended September 30, 2022, the Company acquired several businesses and related assets for approximately $1,013.6 in cash. The purchase consideration for these acquisitions has been allocated under the acquisition method of accounting to the estimated fair market value of the net assets acquired, including approximately $407.4 in identifiable intangible assets and a residual amount of non-tax deductible goodwill of approximately $571.3. The amortization periods for intangible assets acquired from the businesses range from 5 to 23 years for customer relationships, non-compete agreements, technology, and trade names. These acquisitions were made primarily to complement and accelerate the Company’s existing liquid biopsy capabilities and expand the Company’s clinical laboratory services. The preliminary valuation of acquired assets and assumed liabilities, include the following:

The purchase price allocation for several transactions are still preliminary and subject to change. The areas of the purchase price allocation that are not yet finalized relate primarily to contingent purchase price valuation, intangible assets, goodwill, and the impact of finalizing deferred taxes. Accordingly, adjustments may be made as additional information is obtained about the facts and circumstances that existed as of the valuation date. Any adjustments will be recorded in the period in which they are identified.

During the nine months ended September 30, 2021, the Company acquired a business and related assets for approximately $326.0 in cash. The purchase consideration for the acquisition in the nine months ended September 30, 2021, has been allocated under the acquisition method of accounting to the estimated fair market value of the net assets acquired, including approximately $142.5 in identifiable intangible assets and a residual amount of non-tax deductible goodwill of approximately $219.2. The amortization periods for intangible assets acquired from the business range from 5 to 15 years for customer relationships, non-compete agreements, technology and trade names. The acquisition was made primarily to expand the Company's services for hospitals and health system laboratories. The excess of the fair value of the consideration conveyed over the fair value of the net assets acquired was recorded as goodwill. The goodwill reflects the Company's expectations to utilize the acquired business' workforce and established relationships and the benefits of being able to leverage operational efficiencies with favorable growth opportunities in these markets.

Pro Forma Information

Had the Company's total 2021 and 2022 acquisitions been completed as of January 1, 2021, the Company's pro forma results would have been as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2022		2021		2022		2021
Revenues	$	3,754.1	$	4,071.5	$	11,663.8	$	12,104.1
Net earnings attributable to Laboratory Corporation of America Holdings	$	352.0	$	584.6	$	1,201.8	$	1,811.1

4.    EARNINGS PER SHARE

Basic earnings per share is computed by dividing net earnings attributable to Laboratory Corporation of America Holdings by the weighted average number of common shares 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:

	Three Months Ended September 30,										Nine Months Ended September 30,

Diluted earnings per share represent the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. These potential shares include dilutive stock options and unissued restricted stock awards. The following table summarizes the potential common shares not included in the computation of diluted earnings per share because their impact would have been antidilutive:

	Three Months Ended September 30,		Nine Months Ended September 30,
	2022	2021	2022	2021
Employee stock options and awards	0.2	—	0.2	0.1

5.    GOODWILL AND INTANGIBLE ASSETS

The changes in the carrying amount of goodwill for the nine months ended September 30, 2022, are as follows:

	Dx		DD		Total
Balance as of December 31, 2021	$	4,046.2	$	3,912.7	$	7,958.9
Goodwill acquired during the period	453.5		117.8		571.3
Foreign currency impact and other adjustments to goodwill	(70.2)		(242.4)		(312.6)
Balance as of September 30, 2022	$	4,429.5	$	3,788.1	$	8,217.6

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 April 30, 2021. 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 0.23%, 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 under the facility. There were no balances outstanding on the Company's current revolving credit facility as of September 30, 2022 and December 31, 2021. As of September 30, 2022, the effective interest rate on the revolving credit facility was 4.14%. 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, 2022, and expects that it will remain in compliance with its existing debt covenants for the next twelve months.

There were $79.8 in outstanding letters of credit as of September 30, 2022.

At inception, the Company paid $1,000.0 and received 2.7 shares based on a calculation using 80% of the shares calculated at the price at the inception of the ASR agreements with two different banks, Goldman Sachs & Co. LLC (Goldman Sachs) and Barclays Bank PLC (Barclays). The initial shares received under the ASR were removed from the outstanding share count in 2021. In March 2022, the Company received 0.6 shares of its common stock, arising from a partial acceleration with Barclays and a final settlement from Goldman Sachs, based on the average daily volume weighted average price per share of $277.40. In April 2022, the Company received 0.2 shares of its common stock for final settlement from Barclays based on the average volume-weighted average price per share of $275.51.

8.    COMMITMENTS AND CONTINGENCIES

The Company 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 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 drug development support services. The healthcare diagnostics and drug development 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 probable and estimable and would exceed the aggregate legal reserve. When loss contingencies are not both probable and 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 estimable, and it does not believe they will have a material adverse effect on the Company's financial statements.

As previously reported, the Company responded to an October 2007 subpoena from the U.S. Department of Health & Human Services Office of Inspector General's regional office in New York. On August 17, 2011, the U.S. District Court for the Southern District of New York unsealed a False Claims Act lawsuit, United States of America ex rel. NPT Associates v. Laboratory Corporation of America Holdings, which alleges that the Company offered UnitedHealthcare kickbacks in the form

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(dollars and shares in millions, except per share data)

of discounts in return for Medicare business. The Plaintiff's Third Amended Complaint further alleges that the Company's billing practices violated the False Claims Acts of 14 states and the District of Columbia. The lawsuit seeks actual and treble damages and civil penalties for each alleged false claim, as well as recovery of costs, attorney's fees, and legal expenses. The Company's Motion to Dismiss was granted in October 2014 and Plaintiff was granted the right to replead. On January 11, 2016, Plaintiff filed a motion requesting leave to file an amended complaint under seal and to vacate the briefing schedule for the Company's Motion to Dismiss, while the government reviewed the amended complaint. The Court granted the motion and vacated the briefing dates. Plaintiff then filed the Amended Complaint under seal. On August 24, 2021, the U.S. government filed a notice indicating that it did not intend to intervene in the matter. On October 27, 2021, the Fourth Amended Complaint was unsealed. The Fourth Amended Complaint is similar to the Third Amended Complaint in that it alleges that the Company offered UnitedHealthcare kickbacks in the form of discounts in return for Medicare and Medicaid business, and it further alleges that the Company unlawfully charged Medicare amounts substantially in excess of its alleged usual charges. Similar to the Third Amended Complaint, the Fourth Amended Complaint alleges violations of the federal False Claims Act and the False Claims Act of 14 states and the District of Columbia. On February 3, 2022, the Company filed a Motion to Dismiss all claims. On August 29, 2022, the Court entered an order granting the Motion to Dismiss and declining to exercise supplemental jurisdiction over the state law claims. Should the Plaintiff seek an appeal, the Company will vigorously defend the lawsuit.

In addition, the Company has received various other subpoenas since 2007 related to Medicaid billing. In October 2009, the Company received a subpoena from the State of Michigan Department of Attorney General seeking documents related to its billing to Michigan Medicaid. The Company cooperated with this request. 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. 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.

In December 2014, the Company received a Civil Investigative Demand issued pursuant to the U.S. False Claims Act from the U.S. Attorney's Office for South Carolina, which requested information regarding alleged remuneration and services provided by the Company to physicians who also received draw and processing/handling fees from competitor laboratories Health Diagnostic Laboratory, Inc. (HDL) and Singulex, Inc. (Singulex). The Company cooperated with the request. On April 4, 2018, the U.S. District Court for the District of South Carolina, Beaufort Division, unsealed a False Claims Act lawsuit, United States of America ex rel. Scarlett Lutz, et al. v. Laboratory Corporation of America Holdings, which alleges that the Company's financial relationships with referring physicians violate federal and state anti-kickback statutes. The Plaintiffs' Fourth Amended Complaint further alleges that the Company conspired with HDL and Singulex in violation of the Federal False Claims Act and the California and Illinois insurance fraud prevention acts by facilitating HDL's and Singulex's offers of illegal inducements to physicians and the referral of patients to HDL and Singulex for laboratory testing. The lawsuit seeks actual and treble damages and civil penalties for each alleged false claim, as well as recovery of costs, attorney's fees, and legal expenses. Neither the U.S. government nor any state government has intervened in the lawsuit. The Company filed a Motion to

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 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. On January 22, 2020, the Company filed Motions to Dismiss all claims. 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 sought damages on behalf of a class of all affected Company customers. 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 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 lawsuit will be vigorously defended.

Certain governmental entities have requested information from the Company related to the AMCA Incident.

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 16 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 $4,921.2 and $5,841.1 as of September 30, 2022, and December 31, 2021,

19

(dollars and shares in millions, except per share data)

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.

Cross Currency Swap

During the fourth quarter of 2018, the Company entered into U.S. Dollar (USD) to Swiss Franc cross-currency swap agreements with an aggregate notional value of $600.0. During the second quarter of 2022, the Company terminated $300.0 of those cross-currency swap agreements and entered into new USD to Swiss Franc cross-currency swap agreements with an aggregate notional value of $300.0 that mature in 2024. In May 2022, the Company reclassified a gain of $0.9 to the Consolidated Statement of Operations within other, net, due to the exit of $300.0 of the cross-currency swap agreements. These instruments are designated as a hedge against the impact of foreign exchange movements on its net investment in a Swiss subsidiary. These cross currency swaps are included in other long-term liabilities as appropriate with an aggregate fair value of $8.1 and $32.8 as of September 30, 2022 and December 31, 2021, respectively. Changes in the fair value of the cross-currency swaps are charged or credited through accumulated other comprehensive income in the Consolidated Balance Sheet until the hedged item is recognized in earnings. The cumulative amount of the fair value hedging adjustments are recognized as currency translation within the Consolidated Statement of Comprehensive Earnings.

GENERAL (dollars in millions, except per share data)

Revenues for the nine months ended September 30, 2022, were $11,202.6, a decrease of 7.1% from $12,064.8 during the nine months ended September 30, 2021. The decrease was due to lower organic revenue of 6.9% and unfavorable foreign currency translation of 0.9%, partially offset by acquisitions net of divestitures of 0.6%. The 6.9% decline in organic revenue includes a 8.9% decrease in COVID-19 PCR and antibody testing (COVID-19 Testing), partially offset by a 2.0% increase in the Company's organic Base Business. Base Business includes the Company's business 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.

Proposed Spin-Off of Clinical Development Business

On July 28, 2022, the Company announced that its board of directors authorized the Company to pursue a spin-off of its wholly owned Clinical Development business, which includes the parts of its DD segment focused on providing Phase I-IV clinical trials, market access, and technology solutions to pharmaceutical and biotechnology organizations. The planned spin-off would result in two independent, publicly traded companies. The spin-off is intended to be a tax-free transaction to the Company and its stockholders for U.S. federal income tax purposes and is expected to be effected through a dividend of the Clinical Development business' shares to the Company's shareholders. The Company anticipates that, consistent with any applicable legal and tax requirements, there will be ongoing transitional and commercial arrangements to provide for a seamless delivery of services to the customers and other stakeholders of the independent companies following the spin-off. The Company is targeting completion of the spin-off with an accelerated timeframe of mid-2023, subject to the satisfaction of certain customary conditions, including receipt of final approval by the Company's board of directors, receipt of appropriate assurances regarding the tax-free nature of the transaction, and the effectiveness of any required filings with the SEC. There can be no assurances regarding the ultimate timing of the transaction or that the spin-off will be completed.

RESULTS OF OPERATIONS (dollars in millions)

Three months ended September 30, 2022, compared with three months ended September 30, 2021

Revenues

	Three Months Ended September 30,
	2022		2021		Change
Dx	$	2,207.6	$	2,617.5	(15.7)	%
DD	1,405.8		1,459.5		(3.7)	%
Intercompany eliminations and other	(7.3)		(14.4)		49.3	%
Total	$	3,606.1	$	4,062.6	(11.2	%)

Total revenues for the three months ended September 30, 2022, were $3,606.1, a decrease of 11.2% over $4,062.6 in the third quarter of 2021. The decrease was due to lower organic revenue of 10.7% and unfavorable foreign currency translation of 1.3%, partially offset by acquisitions of 0.8%. The 10.7% decrease in organic revenue was driven by a 11.8% decrease in COVID-19 Testing, partially offset by a 1.1% increase in the Company's organic Base Business.

Dx revenues for the three months ended September 30, 2022, were $2,207.6, a decrease of 15.7% over $2,617.5 in the third quarter of 2021. The decrease was primarily due to organic revenue of 16.4% and unfavorable foreign currency translation of

24

0.1%, partially offset by acquisitions of 0.9%. The 16.4% decrease in organic revenue was due to a 18.4% decrease in COVID-19 Testing, partially offset by a 1.9% increase in the Base Business. Total Base Business growth compared to the Base Business in the prior year was 3.7%.

Dx total volume (measured by requisitions) for the three months ended September 30, 2022, decreased by 10.3% as organic volume decreased by 10.9% and acquisition volume contributed 0.6%. Organic volume was impacted by an 12.8% decrease in COVID-19 Testing, partially offset by a 1.9% increase in Base Business. Price/mix decreased by 5.4% due to a decrease in COVID-19 Testing of 5.5%. Base Business volume was up 3.1% compared to the Base Business last year, while price/mix was up 0.6%.

DD revenues for the three months ended September 30, 2022, were $1,405.8, a decrease of 3.7% over $1,459.5 in the third quarter of 2021. The decrease was primarily due to unfavorable foreign currency translation of 3.4%. The benefit of acquisitions of 0.5% was offset by a 0.7% decline in Base Business organic growth, which was negatively impacted by approximately 5.0% due to reduced COVID-19 related work and the Ukraine/Russia crisis. COVID-19 related work includes lower COVID-19 vaccine and therapeutic studies as well as reduced clinical development kits shipped and returned due to supply chain issues and labor constraints.

Cost of Revenues

	Three Months Ended September 30,
	2022			2021			Change
Cost of revenues	$	2,546.4		$	2,677.1		(4.9)	%
Cost of revenues as a % of revenues	70.6		%	65.9		%

Cost of revenues as a percentage of revenues during the three months ended September 30, 2022, increased to 70.6% as compared to 65.9% in the corresponding period in 2021. This increase in cost of revenues as a percent of revenues was primarily due to a reduction in COVID-19 Testing revenues, higher personnel expenses, and other inflationary costs, partially offset by organic Base Business growth and LaunchPad savings.

Selling, General and Administrative Expenses

	Three Months Ended September 30,
	2022			2021			Change
Selling, general and administrative expenses	$	510.0		$	519.9		(1.9)	%

Selling, general and administrative expenses as a percentage of revenues were 14.1% and 12.8% during the three months ended September 30, 2022, and 2021, respectively. The increase is primarily due to a reduction in COVID-19 Testing revenues, partially offset by LaunchPad savings.

DD	32.7		62.9		(48.1)	%
Total amortization of intangibles and other assets	$	65.2	$	92.2	(29.3)	%

The decrease in amortization of intangibles and other assets primarily reflects the completion of the accelerated amortization related to the Covance trade name as a result of a rebranding initiative that resulted in $30.2 of expense in the three months ended September 30, 2021, offset by additional amortization for assets acquired subsequent to September 30, 2021.

Restructuring and Other Charges

	Three Months Ended September 30,

The charges were comprised of $2.5 related to severance and other personnel costs and $11.4 in facility closures, lease terminations, and general integration activities. The charges were adjusted by the increase of $1.5 of previously established severance liabilities and the reversal of previously established liability of $0.3 in unused facility-related costs.

During the three months ended September 30, 2021, the Company recorded net restructuring and other charges of $6.5: $3.3 within Dx and $3.2 within DD. The charges were comprised of $3.3 related to severance and other personnel costs and

Interest Expense

	Three Months Ended September 30,
	2022		2021		Change
Interest expense	$	(46.3)	$	(42.2)	9.9	%

The increase in interest expense for the three months ended September 30, 2022, as compared with the corresponding period in 2021, is primarily due to the increased interest rates on variable rate debt, and lower benefit from cross currency swaps, partly offset by the impact of higher interest rates on cash.

Equity Method Income

	Three Months Ended September 30,
	2022		2021		Change
Equity method income, net	$	1.7	$	8.4	(79.3)	%

 Equity method income represents the Company's ownership share in joint venture partnerships along with equity investments in other companies in the health care industry. The decrease in income for the three months ended September 30, 2022, as compared with the corresponding period in 2021, was primarily due to the decreased profitability of the Company's joint ventures in 2022.

Other, net

	Three Months Ended September 30,
	2022		2021		Change
Other, net	$	(7.3)	$	31.9	(123.0)	%

 The change in Other, net for the three months ended September 30, 2022, as compared to the three months ended September 30, 2021, is primarily due to investment losses of $5.2 for the three months ended September 30, 2022 compared to investment gains of $36.9 for the corresponding period of 2021.

	2022			2021			Change
Income tax expense	$	68.4		$	180.4		(62.1)	%
Income tax expense as a % of earnings before income taxes	16.2		%	23.5		%

The current year effective tax rate was favorably impacted by the Company's foreign income inclusion and research and development tax credits. During the quarter, the Company completed a detailed research and development tax credit analysis for the 2019, 2020, and 2021 tax years that resulted in an incremental income tax benefit. The prior year effective tax rate was favorably impacted by stock-based compensation arrangements that was offset by the deferred revaluation related to the United Kingdom rate change.

	2022			2021			Change
Dx operating income	$	378.7		$	722.7		(47.6)	%

The decrease in adjusted operating income and adjusted operating margin was primarily due to a reduction in COVID-19 Testing, higher personnel expense, and other inflationary costs, partially offset by organic Base Business growth and LaunchPad savings.

DD operating income was $156.7 for the three months ended September 30, 2022, an increase of $15.2 over operating income of $141.6 in the corresponding period of 2021. The increase was primarily due to less amortization expense in 2022 as a

26

result of the completion of the accelerated amortization related to the Covance trade name, organic Base Business growth, and LaunchPad savings, partially offset by a reduction in COVID-19 related work, the Ukraine/Russia crisis, inflationary costs, and the mix impact of acquisitions.

General corporate expenses are comprised primarily of administrative services such as executive management, human resources, legal, finance, corporate affairs, and information technology. Corporate expenses were $66.0 for the three months ended September 30, 2022, a decrease of $31.4 over corporate expenses of $97.4 in the corresponding period of 2021, primarily due to lower personnel costs, bonus allocation, and research and development costs.

General corporate expenses	(206.1)			(191.8)			(14.3)
Total operating income	$	1,683.2		$	2,528.9		$	(845.7)

Dx operating income was $1,457.5 for the nine months ended September 30, 2022, a decrease of $817.9 from operating income of $2,275.4 in the corresponding period of 2021, and Dx operating margin decreased 830 basis points year-over-year. The decrease in adjusted operating income and adjusted operating margin was primarily due to a reduction in COVID-19 Testing, higher personnel expense, and other inflationary costs, partially offset by organic Base Business growth and LaunchPad savings.

DD operating income was $431.8 for the nine months ended September 30, 2022, a decrease of $13.4 from operating income of $445.3 in the corresponding period of 2021. The decrease was primarily due to a reduction in COVID-19 Testing, a reduction in COVID-19 related work, the interruption of some clinical trial activity due to the conflict in Ukraine, higher personnel expense, and other inflationary costs. These impacts were partially offset by less amortization expense as a result of the completion of the accelerated amortization related to the Covance trade name, organic Base Business growth and LaunchPad savings.

General corporate expenses are comprised primarily of administrative services such as executive management, human resources, legal, finance, corporate affairs, and information technology. Corporate expenses were $206.1 for the nine months ended September 30, 2022, an increase of $14.3 over corporate expenses of $191.8 in the corresponding period of 2021, primarily due to higher personnel costs, bonus allocation, research and development costs, and other costs.

The Company remains on track to deliver approximately $350.0 of net savings from its three-year LaunchPad initiative by the end of 2024.

LIQUIDITY AND CAPITAL RESOURCES (dollars and shares in millions)

The Company's cash-generating ability and financial condition typically have provided ready access to capital markets. The Company's principal source of liquidity is operating cash flow, supplemented by proceeds from debt offerings. The Company's senior unsecured revolving credit facility is further discussed in Note 6 (Debt) to the Company's condensed consolidated financial statements.

29

In summary, the Company's cash flows were as follows for the nine months ended September 30, 2022, and 2021, respectively:

	Nine Months Ended September 30,
	2022		2021
Net cash provided by operating activities	$	1,302.3	$	2,412.1
Net cash used for investing activities	(1,378.9)		(630.1)
Net cash used for financing activities	(949.6)		(1,057.2)
Effect of exchange rate changes on cash and cash equivalents	(36.6)		(9.1)
Net increase (decrease) in cash and cash equivalents	$	(1,062.8)	$	715.7

Cash and Cash Equivalents

Cash and cash equivalents at September 30, 2022, and 2021, totaled $409.9 and $2,036.5, respectively. Cash and cash equivalents consist of highly liquid instruments, such as time deposits, commercial paper, and other money market investments, which have original maturities of three months or less.

Cash Flows from Operating Activities 

During the nine months ended September 30, 2022, the Company's operations provided $1,302.3 of cash as compared to $2,412.1 during the same period in 2021. The $1,109.8 decrease in cash provided from operations in 2022 as compared with the corresponding 2021 period is primarily due to lower cash earnings and unfavorable working capital requirements.

Cash Flows from Investing Activities

Net cash used for investing activities for the nine months ended September 30, 2022, was $1,378.9 as compared to $630.1 for the nine months ended September 30, 2021. The change in cash used for investing activities was primarily due to an increase in business acquisitions and higher capital expenditures during the nine months ended September 30, 2022. Capital expenditures were $364.0 and $310.4 for the nine months ended September 30, 2022, and 2021, respectively.

Cash Flows from Financing Activities

Net cash used by financing activities for the nine months ended September 30, 2022, was $949.6 as compared to $1,057.2 for the nine months ended September 30, 2021. The change in cash flows from financing activities for the nine months ended September 30, 2022, as compared to the nine months ended September 30, 2021, was primarily due to the repayment of the 2019 Term Loan in 2021, the payment of dividends of $131.6 in 2022, and an increase of $131.5 in share repurchases.

At September 30, 2022, the Company had $409.9 of cash and $1,000.0 of available borrowings under its revolving credit facility, which does not mature until 2026. Under the Company's 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 under the revolving credit facility at September 30, 2022, and expects that it will remain in compliance with its existing debt covenants for the next twelve months.

For the nine months ended September 30, 2022, the Company purchased 3.3 shares of its common stock at a total cost of $800.0. As of September 30, 2022, the Company had an outstanding authorization from the board of directors to purchase up to $831.5 more of the Company's common stock with no expiration date.

For the nine months ended September 30, 2022, the Company paid $131.6 in common stock dividends. On October 12, 2022, the Company announced a cash dividend of $0.72 per share of common stock for the fourth quarter, or approximately $64.9 in the aggregate. The dividend will be payable on December 9, 2022, to stockholders of record of all issued and outstanding shares of common stock as of the close of business on November 17, 2022. The declaration and payment of any future dividends will be at the discretion of the Company's board of directors.

Credit Ratings

The Company’s investment grade debt ratings from Moody’s and from Standard and Poor’s (S&P) contribute to its ability to access capital markets.

ITEM 3. Quantitative and Qualitative Disclosures about Market Risk (dollars in millions)

Market risk is the potential loss arising from adverse changes in market rates and prices, such as foreign currency exchange rates, interest rates, and other relevant market rate or price changes. In the ordinary course of business, the Company is exposed to various market risks, including changes in foreign currency exchange and interest rates, and the Company regularly evaluates its exposure to such changes. The Company addresses its exposure to market risks, principally the market risks associated with changes in foreign currency exchange rates and interest rates, through a controlled program of risk management that includes,

30

from time to time, the use of derivative financial instruments such as foreign currency forward contracts, and interest rate and cross currency swap agreements.

Foreign Currency Exchange Rates

Approximately 15.1% of the Company's revenues for the nine months ended September 30, 2022, and approximately 15.2% of the Company's revenue for the nine months ended September 30, 2021, 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 2022 and the year ended December 31, 2021, the most significant currency exchange rate exposures were to the Canadian dollar, Swiss Franc, Euro and British Pound. Excluding the 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, 2022, by approximately $20.6. Gross accumulated currency translation adjustments recorded as a separate component of shareholders’ equity were $(572.2) and $(114.6) at September 30, 2022 and 2021, 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, 2022, the Company had 24 open foreign exchange forward contracts relating to service contracts with various amounts maturing monthly through October 2022 with a notional value totaling approximately $670.3. At December 31, 2021, the Company had 28 open foreign exchange forward contracts relating to service contracts with various amounts maturing monthly through January 2022 with a notional value totaling approximately $600.7.

The Company is party to U.S. to Swiss Franc cross-currency swap agreements with an aggregate notional amount of $600.0, $300.0 maturing in 2024 and $300.0 maturing in 2025, 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 LIBOR 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(e) 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, 2022.

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, 2022, that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

See Note 8 (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, 2021. 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, 2021.

The planned spin-off of the Company’s Clinical Development business may not be completed on the terms or timeline currently contemplated, if at all, and may not achieve the intended results.

The Company intends to pursue a spin-off of its wholly owned Clinical Development business, which includes the parts of its DD segment focused on providing Phase I-IV clinical trial management, market access, and technology solutions to pharmaceutical and biotechnology organizations, which would result in two independent, publicly traded companies. Unanticipated issues including, but not limited to, the failure to obtain regulatory approval, obtain appropriate assurances regarding the tax-free nature of the spin-off, or have the Form 10 registration statement that will be filed with the SEC declared effective on a timely basis or at all, could delay, prevent, or otherwise adversely affect the planned spin-off. There can be no assurance that the conditions of the spin-off will be satisfied or that Company will be able to complete the spin-off on the terms or on the anticipated timeline, or at all.

The Company expects that pursuing and implementing the spin-off will continue to require significant expenses and management time and effort, may divert management’s attention from the Company and Clinical Development's ongoing business operations and may adversely impact relationships with customers, suppliers, employees, and other business counterparties. The Company may experience delays, business disruption, increased costs, including from lost synergies or from restructuring transactions, negative market reaction to the announcement and planning for the transaction, change in market receptiveness to effect transactions in the capital markets, and other challenges during or following the spin-off, which could adversely affect the Company’s business, financial condition, and results of operations. The Company may also experience increased challenges in attracting, retaining, and motivating key personnel during the pendency of the spin-off and following its completion, which could harm the Company’s business. The Company anticipates that, consistent with any applicable legal and tax requirements, there will be ongoing transitional and commercial arrangements to provide for a seamless delivery of services to the customers and other stakeholders of the independent companies following the spin-off, but those arrangements may not meet the intended objectives, which could negatively impact the Company’s and Clinical Development’s business, including relationships with customers and other business counterparties.

Further, if the planned spin-off is completed, the anticipated benefits of the transaction may not be realized within the expected time periods or at all. Failure to implement the planned spin-off effectively or the negative reaction of customers, the Company’s employees, and other stakeholders could also result in a decline in value of one or both of the companies.

Increased regulations and restrictions on the import of research animals, limitations of supply of research animals, and actions of animal rights activists may have an adverse effect on the Company.

DD's preclinical services utilize animals in preclinical testing of the safety and efficacy of drugs and devices. Such activities are required for the development of new medicines and medical devices under regulatory regimes in the U.S., Europe, Japan, and other countries. Increased regulations and restrictions on the import of research animals into various countries, as well as limitations of supply, could impact DD’s ability to conduct preclinical research and could have an adverse effect on DD’s financial condition, results of operations, and cash flows. In addition, acts of vandalism and other acts by animal rights activists who object to the use of animals in drug development could have an adverse effect on the Company.

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 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.

32

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 has not been finalized, and the FDA has instead continued its enforcement discretion policy and has indicated that it intends to work with Congress to enact comprehensive legislative reform of diagnostics oversight. As such, LDTs developed by high complexity clinical laboratories are currently generally offered as services to health care providers under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) regulatory framework administered by the Centers for Medicare and Medicaid Services (CMS), without the requirement for FDA clearance or approval. There are other regulatory and legislative proposals that would increase general FDA oversight of clinical laboratories and LDTs. The outcome and ultimate impact of such proposals on the business is difficult to predict at this time. On February 20, 2020, the FDA issued a statement with a table of pharmacogenetic associations setting forth certain gene-drug interactions that the agency has 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 while it is committed to work with Congress on new comprehensive diagnostic oversight reform legislation, it could still take enforcement actions under the current medical device framework regarding diagnostic claims the agency determines not to be sufficiently supported. Even without issuance of a finalized LDT oversight framework, in light of the April 4, 2019, FDA warning letter issued to Inova Genomics Laboratory related to certain LDTs that Inova offered, as well as the February 2020 pharmacogenetics statement, there may be an increased risk of FDA enforcement actions for laboratory tests offered by companies without FDA clearance or approval.

Current FDA regulation of the Company’s diagnostic products and the potential for future increased regulation of the Company’s LDTs in the future 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, which could have a material adverse effect upon the Company.

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 DD. For example, the European Union In Vitro Diagnostics Regulation (Regulation (EU) 2017/746 (EU IVDR)), which became applicable on May 26, 2022, establishes 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 DD's services, could impact DD's ability to support trials, and could result in increased costs and administrative and legal actions, and have an adverse effect on DD's financial condition, results of operations, and cash flows.

BASIS OF FINANCIAL STATEMENT PRESENTATION

Laboratory Corporation of America® Holdings (Labcorp® or the Company) is a leading global life sciences company that provides vital information to help doctors, hospitals, pharmaceutical companies, researchers, and patients make clear and confident decisions. By leveraging its strong diagnostics and drug development capabilities, the Company provides insights and accelerates innovations to improve health and improve lives.

The Company reports its business in two segments, Labcorp Diagnostics (Dx) and Labcorp Drug Development (DD). For further financial information about these segments, see Note 11 (Business Segment Information) to the Condensed Consolidated Financial Statements. During the three months ended September 30, 2022, Dx and DD contributed approximately 61% and 39%, respectively, of revenues to the Company. During the nine months ended September 30, 2022, Dx and DD contributed approximately 61% and 39%, respectively, of revenues to the Company.

On July 28, 2022, the Company announced that its board of directors authorized the Company to pursue a spin-off of its wholly owned Clinical Development business, which includes parts of its DD segment focused on providing Phase I-IV clinical trial management, market access, and technology solutions to pharmaceutical and biotechnology organizations. The planned spin-off will result in two independent, publicly traded companies. The spin-off is intended to be a tax-free transaction to the Company and its stockholders for United States (U.S.) federal income tax purposes and is expected to be effected through a dividend of the Clinical Development business’ shares to the Company's shareholders. The Company anticipates that, consistent with any applicable legal and tax requirements, there will be ongoing transitional and commercial arrangements to provide for a seamless delivery of services to the customers and other stakeholders of the independent companies following the spin-off. The Company is targeting completion of the spin-off with an accelerated timeframe of mid-2023. The spin-off will be subject to the satisfaction of certain customary conditions, including, among others, the receipt of final approval by the Company's board of directors, the receipt of appropriate assurances regarding the tax-free nature of the separation, and the effectiveness of any required filings with the U.S. Securities and Exchange Commission (SEC).

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.

BASIS OF FINANCIAL STATEMENT PRESENTATION

Laboratory Corporation of America® Holdings (Labcorp® or the Company) is a leading global life sciences company that provides vital information to help doctors, hospitals, pharmaceutical companies, researchers, and patients make clear and confident decisions. By leveraging its strong diagnostics and drug development capabilities, the Company provides insights and accelerates innovations to improve health and improve lives.

The Company reports its business in two segments, Labcorp Diagnostics (Dx) and Labcorp Drug Development (DD). For further financial information about these segments, see Note 11 (Business Segment Information) to the Condensed Consolidated Financial Statements. During the three months ended September 30, 2022, Dx and DD contributed approximately 61% and 39%, respectively, of revenues to the Company. During the nine months ended September 30, 2022, Dx and DD contributed approximately 61% and 39%, respectively, of revenues to the Company.

On July 28, 2022, the Company announced that its board of directors authorized the Company to pursue a spin-off of its wholly owned Clinical Development business, which includes parts of its DD segment focused on providing Phase I-IV clinical trial management, market access, and technology solutions to pharmaceutical and biotechnology organizations. The planned spin-off will result in two independent, publicly traded companies. The spin-off is intended to be a tax-free transaction to the Company and its stockholders for United States (U.S.) federal income tax purposes and is expected to be effected through a dividend of the Clinical Development business’ shares to the Company's shareholders. The Company anticipates that, consistent with any applicable legal and tax requirements, there will be ongoing transitional and commercial arrangements to provide for a seamless delivery of services to the customers and other stakeholders of the independent companies following the spin-off. The Company is targeting completion of the spin-off with an accelerated timeframe of mid-2023. The spin-off will be subject to the satisfaction of certain customary conditions, including, among others, the receipt of final approval by the Company's board of directors, the receipt of appropriate assurances regarding the tax-free nature of the separation, and the effectiveness of any required filings with the U.S. Securities and Exchange Commission (SEC).

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 SHAREBasic earnings per share is computed by dividing net earnings attributable to Laboratory Corporation of America Holdings by the weighted average number of common shares 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:

Diluted earnings per share represent the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock. These potential shares include dilutive stock options and unissued restricted stock awards. The following table summarizes the potential common shares not included in the computation of diluted earnings per share because their impact would have been antidilutive:

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 16 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 $4,921.2 and $5,841.1 as of September 30, 2022, and December 31, 2021,

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.

BUSINESS SEGMENT INFORMATION

The following table is a summary of segment information for the three and nine months ended September 30, 2022, and 2021. 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 as 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. Operating earnings of each segment represent revenues less directly identifiable expenses to arrive at operating income for the segment. General management and administrative corporate expenses are included in general corporate expenses below.

5.    GOODWILL AND INTANGIBLE ASSETS

The changes in the carrying amount of goodwill for the nine months ended September 30, 2022, are as follows:

	Dx		DD		Total
Balance as of December 31, 2021	$	4,046.2	$	3,912.7	$	7,958.9
Goodwill acquired during the period	453.5		117.8		571.3

Balance as of September 30, 2022	$	4,429.5	$	3,788.1	$	8,217.6

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 components of identifiable intangible assets are as follows:

	September 30, 2022						December 31, 2021
	Gross Carrying Amount		Accumulated Amortization		Net		Gross Carrying Amount		Accumulated Amortization		Net

The Company expects to recognize revenue over the remaining contract term of the individual projects, with contract terms generally ranging from 1 to 8 years.

Within DD, revenues of $6.6 and $10.1 were recognized during the three months ended September 30, 2022 and 2021, respectively, and revenues of $75.8 and $38.9 were recognized during the nine months ended September 30, 2022 and 2021, respectively, from performance obligations that were satisfied in previous periods. This revenue primarily relates to adjustments related to changes in scope in full service clinical studies, and to a lesser extent, changes in estimates.

The changes in the carrying amount of goodwill for the nine months ended September 30, 2022, are as follows:

	Dx		DD		Total
Balance as of December 31, 2021	$	4,046.2	$	3,912.7	$	7,958.9

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 components of identifiable intangible assets are as follows:

	September 30, 2022						December 31, 2021
	Gross Carrying Amount		Accumulated Amortization		Net		Gross Carrying Amount		Accumulated Amortization		Net

Amortization of intangible assets for the three and nine months ended September 30, 2022, and 2021, was $65.2 and $92.2 and $198.7 and $276.7, respectively. The amortization expense for the net carrying amount of intangible assets is estimated to be $58.6 for the remainder of fiscal 2022, $264.4 in fiscal 2023, $258.9 in fiscal 2024, $244.2 in fiscal 2025, $234.5 in fiscal 2026, and $2,194.2 thereafter.
