Rhea-AI Filing Summary

Disc Medicine, Inc. (IRON) filed a Form 144 indicating a proposed sale of 53,215 common shares through Merrill Lynch. At the most recent market price used in the filing, the shares are valued at $3.23 million. The filing lists total shares outstanding at 34,634,295, so the planned sale represents roughly 0.15 % of outstanding stock, a modest proportion that limits potential market impact.

The seller acquired the stock on 05 May 2020 via a private placement for cash. In the past three months related entities—Atlas Venture Fund X, L.P. and Atlas Venture Opportunity Fund I, L.P.—sold a combined 1,848 shares for gross proceeds of $112,964. The anticipated sale date for the new block is 23 July 2025, and the shares are expected to be sold on the Nasdaq exchange.

Disc Medicine, Inc. (IRON) ha presentato un Modulo 144 che indica una proposta di vendita di 53.215 azioni ordinarie tramite Merrill Lynch. Al prezzo di mercato più recente utilizzato nella comunicazione, le azioni sono valutate a 3,23 milioni di dollari. Il documento riporta un totale di azioni in circolazione pari a 34.634.295, quindi la vendita prevista rappresenta circa lo 0,15% del capitale azionario, una quota modesta che limita l'impatto potenziale sul mercato.

Il venditore ha acquisito le azioni il 5 maggio 2020 tramite un collocamento privato a fronte di un pagamento in contanti. Negli ultimi tre mesi, entità correlate — Atlas Venture Fund X, L.P. e Atlas Venture Opportunity Fund I, L.P. — hanno venduto complessivamente 1.848 azioni per un ricavo lordo di 112.964 dollari. La data prevista per la vendita del nuovo blocco è il 23 luglio 2025 e le azioni dovrebbero essere vendute sul mercato Nasdaq.

Disc Medicine, Inc. (IRON)는 Form 144를 제출했습니다 이 서류는 Merrill Lynch를 통해 53,215 보통주 매각을 제안하는 내용입니다. 제출서류에 사용된 최근 시장 가격 기준으로, 해당 주식의 가치는 323만 달러에 달합니다. 총 발행 주식 수는 34,634,295주로 기재되어 있어, 이번 매각은 전체 발행 주식의 약 0.15%에 해당하는 소규모 비중으로, 시장에 미치는 잠재적 영향은 제한적입니다.

매도인은 2020년 5월 5일 현금 사모 배정을 통해 주식을 취득했습니다. 최근 3개월 동안 관련 기관인 Atlas Venture Fund X, L.P.와 Atlas Venture Opportunity Fund I, L.P.는 총 1,848주를 매도하여 총 수익 112,964달러를 올렸습니다. 새 매각 예정일은 2025년 7월 23일이며, 주식은 나스닥 거래소에서 매각될 예정입니다.

Positive
  • Sale represents only ~0.15 % of shares outstanding, suggesting minimal dilution and limited potential impact on the float.
Negative
  • Insider/affiliate intends to liquidate $3.23 M in stock, which could introduce modest selling pressure and signal reduced insider exposure.

Insights

TL;DR: Small insider block (0.15 %) worth $3.2 M slated for 7/23/25; limited dilution but indicates liquidity event.

The Form 144 signals that Atlas-affiliated funds intend to sell 53,215 IRON shares via Merrill Lynch. Given the company’s 34.6 M shares outstanding, the planned disposition is immaterial from a dilution standpoint and unlikely to pressure prices significantly under normal trading volumes. Nonetheless, insider sales can be interpreted as profit-taking or portfolio rebalancing. Investors may monitor whether the transaction completes as scheduled and whether further filings follow.

The Company's Diagnostic Solutions ("DS") group, which represents the balance of the Company's consolidated net revenues, includes the Company's risk assessment services business, which offers solutions for insurers, and the Company's healthcare information technology businesses, which offer solutions for healthcare providers and payers.

2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    Basis of Presentation
    
    The interim unaudited consolidated financial statements reflect all adjustments which in the opinion of management are necessary for a fair statement of results of operations, comprehensive income, financial condition, cash flows and stockholders' equity for the periods presented. Except as otherwise disclosed, all such adjustments are of a normal recurring nature. Operating results for the interim periods are not necessarily indicative of the results that may be expected for the full year. These interim unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company’s 2024 Annual Report on Form 10-K. The year-end balance sheet data was derived from the audited consolidated financial statements as of December 31, 2024 but does not include all the disclosures required by accounting principles generally accepted in the United States (“GAAP”).

    The accounting policies of the Company are the same as those set forth in Note 2 to the audited consolidated financial statements contained in the Company’s 2024 Annual Report on Form 10-K.

    Use of Estimates
    
    The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

    Earnings Per Share

    The Company's unvested restricted stock units that contain non-forfeitable rights to dividends are participating securities and, therefore, are included in the earnings allocation in computing earnings per share using the two-class method. Basic earnings per common share is calculated by dividing net income attributable to Quest Diagnostics, adjusted for earnings allocated to participating securities, by the weighted average number of common shares outstanding. Diluted earnings per common share is calculated by dividing net income attributable to Quest Diagnostics, adjusted for earnings allocated to

(in millions, unless otherwise indicated)


participating securities, by the weighted average number of common shares outstanding after giving effect to all potentially dilutive common shares outstanding during the period. Potentially dilutive common shares include the dilutive effect of outstanding stock options and performance share units granted under the Company's Amended and Restated Employee Long-Term Incentive Plan (“ELTIP”) and its Amended and Restated Non-Employee Director Long-Term Incentive Plan (“DLTIP”), as well as the dilutive effect of accelerated share repurchase agreements, if applicable. Earnings allocable to participating securities include the portion of dividends declared as well as the portion of undistributed earnings during the period allocable to participating securities.

    New Accounting Standards to be Adopted

    In December 2023, the Financial Accounting Standards Board ("FASB") issued a new accounting standard which will require companies to make additional income tax disclosures. The pronouncement is effective for annual filings for the year ended December 31, 2025. The Company does not expect the adoption of this standard to have a material impact on its results of operations, financial position or cash flows.

    In November 2024, the FASB issued a new accounting standard which will require companies to disaggregate certain income statement expenses. The pronouncement is effective for annual filings for the year ended December 31, 2027 and for interim periods within the year ended December 31, 2028. The Company does not expect the adoption of this standard to have a material impact on its results of operations, financial position or cash flows.

    In July 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted. The OBBBA makes permanent key elements of the Tax Cuts and Jobs Act of 2017, including 100% bonus depreciation, domestic research cost expensing and the business interest expense limitation, among other tax changes. Many of the tax provisions of the OBBBA are designed to accelerate tax deductions, which could lead to lower cash tax payments. The new legislation has multiple effective dates, with certain provisions effective in 2025 and others in the future. While the Company continues to assess the impact of the tax provisions of the OBBBA on its consolidated financial statements, the Company currently believes that the tax provisions of the legislation are not expected to have a material impact on the Company’s statement of operations.

4.    RESTRUCTURING ACTIVITIES AND IMPAIRMENT CHARGES

    Invigorate Program

    The Company is engaged in a multi-year program called Invigorate, which includes structured plans to drive savings and improve productivity across the value chain, including in such areas as patient services, logistics and laboratory operations, revenue services, information technology and procurement. The Invigorate program aims to deliver 3% annual cost savings and productivity improvements to partially offset pressures from the current inflationary environment, including labor and benefit cost increases and reimbursement pressures. The Company is leveraging automation and artificial intelligence to improve productivity and also improve quality across the entire value chain, not just in the laboratory. Other areas of focus include reducing denials and patient concessions, enhancing the digital experience, and selecting and retaining talent.

    The Company's pre-tax restructuring charges for the three and six months ended June 30, 2025 included $1 million and $12 million, respectively, of employee separation costs associated with various workforce reduction initiatives as the Company continued to restructure its organization. Additionally, during the three and six months ended June 30, 2025, the Company recorded a $24 million impairment charge on certain long-lived assets related to the potential exit of a business. Of the total restructuring and impairment charges incurred during the three months ended June 30, 2025, $1 million and $24 million were recorded in selling, general and administrative expenses and other operating (income) expense, net, respectively. Of the total restructuring and impairment charges incurred during the six months ended June 30, 2025, $6 million, $6 million and $24 million were recorded in cost of services, selling, general and administrative expenses, and other operating (income) expense, net, respectively.

    The Company's pre-tax restructuring charges for the three and six months ended June 30, 2024 were $8 million and $14 million, respectively, entirely related to employee separation costs associated with various workforce reduction initiatives as the Company continued to restructure its organization. Of the total restructuring charges incurred during the three months ended June 30, 2024, $4 million and $4 million were recorded in cost of services and selling, general and administrative expenses, respectively. Of the total restructuring charges incurred during the six months ended June 30, 2024, $8 million and $6 million were recorded in cost of services and selling, general and administrative expenses, respectively.
    
    Charges for all periods presented were primarily recorded in the Company's DIS business.

    The restructuring liability as of June 30, 2025 and December 31, 2024, which is included in accounts payable and accrued expenses, was $12 million and $13 million, respectively.

5.     BUSINESS ACQUISITIONS

    On August 23, 2024, the Company acquired all of the issued and outstanding common shares of LifeLabs Inc. and all of the partnership interests of BPC Lab Finance LP (collectively, "LifeLabs") in an all-cash transaction for approximately CAN $1.35 billion (approximately USD $1 billion), net of cash acquired. LifeLabs provides laboratory diagnostic information and digital health connectivity systems in Canada. The Company recorded the assets acquired and liabilities assumed based on a preliminary purchase price allocation. During the six months ended June 30, 2025, the Company revised its preliminary purchase price allocation and recorded a $9 million increase to deferred income tax assets and a corresponding decrease to goodwill. The measurement period adjustment did not have a material impact on the Company's consolidated results of operations. The preliminary purchase price allocation is based upon a preliminary valuation and the Company's estimates and assumptions are subject to change within the measurement period as the valuation is finalized.

    The following unaudited pro forma combined financial information reflects the consolidated statement of operations of the Company as if the acquisition of LifeLabs had occurred as of January 1, 2023. The pro forma information includes adjustments primarily related to the amortization of acquired intangible assets, interest expense associated with debt of LifeLabs which was extinguished prior to the acquisition, interest expense associated with senior notes issued to fund the acquisition, the impact on depreciation expense of recording acquired property, plant and equipment at fair value, and transaction costs related to the LifeLabs acquisition. The pro forma combined financial information does not include the estimated annual synergies expected to be realized upon completion of the integration of LifeLabs and therefore is not indicative of the results of operations as they would have been had the transaction been effected on the assumed date (in millions, except per share data).

    During February 2025, the Company entered into a definitive agreement to acquire select assets of Fresenius Medical Care's wholly-owned Spectra Laboratories, a leading provider of renal-specific laboratory testing services in the U.S. The transaction, which is expected to close in the second half of 2025, remains subject to customary closing conditions.

    For details regarding the Company's 2024 acquisitions, see Note 6 to the audited consolidated financial statements in the Company's 2024 Annual Report on Form 10-K.

    A detailed description regarding the Company's fair value measurements is contained in Note 7 to the audited consolidated financial statements in the Company's 2024 Annual Report on Form 10-K.    

    The Company offers certain employees the opportunity to participate in a non-qualified supplemental deferred compensation plan. A participant's deferrals, together with Company matching credits, are invested in a variety of participant-directed stock and bond mutual funds that are classified as trading securities. The trading securities are classified within Level 1 of the fair value hierarchy because the changes in the fair value of these securities are measured using quoted prices in active

(in millions, unless otherwise indicated)


markets based on the market price per unit multiplied by the number of units held, exclusive of any transaction costs. A corresponding adjustment for changes in fair value of the trading securities is also reflected in the changes in fair value of the deferred compensation obligation. The deferred compensation liabilities are classified within Level 2 of the fair value hierarchy because their inputs are derived principally from observable market data by correlation to the trading securities.

    The Company offers certain employees the opportunity to participate in a non-qualified deferred compensation program. A participant's deferrals, together with Company matching credits, are “invested” at the direction of the employee in a hypothetical portfolio of investments which are tracked by an administrator. The Company purchases life insurance policies, with the Company named as beneficiary of the policies, for the purpose of funding the program's liability. Changes in the cash surrender value of the life insurance policies are based upon earnings and changes in the value of the underlying investments. Changes in the fair value of the deferred compensation 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 deferred compensation obligation are classified within Level 2 of the fair value hierarchy because their inputs are derived principally from observable market data by correlation to the hypothetical investments. Deferrals under the plan currently may only be made by participants who made deferrals under the plan in 2017.

    The fair value measurements of the Company's fixed-to-variable interest rate swaps, classified within Level 2 of the fair value hierarchy, are model-derived valuations as of a given date, in which all significant inputs are observable in active markets including certain financial information and certain assumptions regarding past, present and future market conditions.

     During June 2023, the Company acquired Haystack Oncology, Inc. ("Haystack"), an early-stage oncology company focused on minimal residual disease testing to aid in the detection of residual or recurring cancer and better inform therapy decisions. In connection with the acquisition there is a contingent consideration obligation under which the seller can receive up to $100 million of additional consideration dependent upon the achievement of certain revenue benchmarks through 2028 and up to an additional $50 million of consideration dependent upon the Company receiving reimbursement coverage from the Centers for Medicare and Medicaid Services ("CMS"). The portion of the contingent consideration obligation which is dependent upon the achievement of certain revenue benchmarks was measured at fair value using a Monte Carlo method and is classified within Level 3 of the fair value hierarchy as the fair value is determined based on significant inputs that are not observable. Significant inputs include management’s estimate of revenue and other market inputs, including comparable company revenue volatility (35%) and a discount rate (10.5%). The portion of the contingent consideration obligation which is dependent upon the Company receiving reimbursement coverage from the CMS is also classified within Level 3 of the fair value hierarchy as the fair value is principally determined based on management's estimate, which is a significant input that is not observable. Additionally, the fair value of the entire contingent consideration obligation is also impacted by a market discount rate (5%) which adjusts the estimated payments to present value. The fair value of the contingent consideration obligation is not overly sensitive to movements in the comparable company revenue volatility or the discount rate used for the portion of the obligation that is dependent upon the achievement of certain revenue benchmarks. For example, changing the comparable company revenue volatility from 35% to 25% impacts the fair value by $4 million (assuming no other inputs are modified) and changing the discount rate from 10.5% to 7.0% impacts the fair value by $2 million (assuming no other inputs are modified).
    
    The Company has additional contingent consideration obligations in connection with other acquisitions. The liabilities related to such obligations are included in the amounts below.

    The following table provides a reconciliation of the beginning and ending balances of liabilities using significant unobservable inputs (Level 3):
Contingent Consideration

    Of the aggregate $112 million contingent consideration obligation as of June 30, 2025, $84 million and $28 million were included in other liabilities and accounts payable and accrued expenses, respectively, in the Company's consolidated balance sheet. Of the aggregate $106 million contingent consideration obligation as of December 31, 2024, $101 million and $5 million were included in other liabilities and accounts payable and accrued expenses, respectively, in the Company's consolidated balance sheet.

    During the three months ended June 30, 2025, the Company recorded a $24 million impairment charge on certain long-lived assets related to the potential exit of a business. The fair value measurement was classified within Level 3 of the fair value hierarchy as it was based on significant inputs that are not observable.

    In connection with the sale of an 18.9% noncontrolling interest in a subsidiary to UMass Memorial Medical Center ("UMass") on July 1, 2015, the Company granted UMass the right to require the Company to purchase all of its interest in the subsidiary at fair value commencing July 1, 2020. As of June 30, 2025, the redeemable noncontrolling interest was presented at its fair value. The fair value measurement of the redeemable noncontrolling interest is classified within Level 3 of the fair value hierarchy because the fair value is based on a discounted cash flow analysis that takes into account, among other items, the joint venture's expected future cash flows, long term growth rates, and a discount rate commensurate with economic risk.
    
    The carrying amounts of cash and cash equivalents, accounts receivable, and accounts payable and accrued expenses approximate fair value based on the short maturities of these instruments. As of June 30, 2025 and December 31, 2024, the fair value of the Company’s debt was estimated at $5.6 billion and $6.1 billion, respectively. Principally all of the Company's debt is classified within Level 1 of the fair value hierarchy because the fair value of the debt is estimated based on rates currently offered to the Company with identical terms and maturities, using quoted active market prices and yields, taking into account the underlying terms of the debt instruments.

7.    DEBT
    
    During April 2025, the Company amended the agreement for its $750 million senior unsecured revolving credit facility (the “Credit Facility” or "Senior Unsecured Revolving Credit Facility") to extend the maturity to April 2030, while maintaining the borrowing capacity under the facility at $750 million. Under the Credit Facility, the Company can issue letters of credit totaling $150 million (see Note 11). Issued letters of credit reduce the available borrowing capacity under the Credit Facility. Additionally, the Credit Facility includes an additional $500 million uncommitted accordion which, if utilized, brings the total capacity under the facility to $1.3 billion. Interest on the Credit Facility is based on certain published rates plus an applicable margin based on changes in the Company's public debt ratings. At the option of the Company, it may elect to lock into Term Secured Overnight Financing Rate ("Term SOFR")-based interest rate contracts for periods up to six months. For interest on any U.S. Dollar-denominated outstanding amounts not covered under Term SOFR-based interest rate contracts, the Company can opt for an alternate base rate, which is calculated by reference to the prime rate, the federal funds rate or an adjusted Term SOFR rate. The Company also has the option to borrow in other currencies. As of June 30, 2025, the Company's borrowing rate for Term SOFR-based loans under the Credit Facility was adjusted Term SOFR plus 1.00%. The Credit Facility contains various covenants, including the maintenance of a financial leverage ratio, which could impact the Company's ability to, among other things, incur additional indebtedness. As of both June 30, 2025 and December 31, 2024, there were no outstanding borrowings under the Senior Unsecured Revolving Credit Facility.

    During the six months ended June 30, 2025, the Company repaid in full the outstanding indebtedness under the Company's $600 million of 3.50% senior notes, which matured on March 30, 2025.

    The Company has $500 million of 3.45% senior notes due June 2026. The senior notes are included in current portion of long-term debt in the Company's June 30, 2025 consolidated balance sheet. Such notes were included in long-term debt in the Company's December 31, 2024 consolidated balance sheet.

    For further details regarding the Company's debt, see Note 13 to the audited consolidated financial statements in the Company's 2024 Annual Report on Form 10 K.

8.    FINANCIAL INSTRUMENTS

    The Company uses derivative financial instruments, from time to time, to manage its exposure to market risks for changes in interest rates and foreign currencies. This strategy includes the use of interest rate swap agreements, forward-starting interest rate swap agreements, interest rate lock agreements and foreign currency forward contracts to manage its exposure to movements in interest and currency rates. The Company has established policies and procedures for risk assessment and the approval, reporting and monitoring of derivative financial instrument activities. These policies prohibit holding or issuing derivative financial instruments for speculative purposes. The Company does not enter into derivative financial instruments that contain credit-risk-related contingent features or requirements to post collateral.

    Interest Rate Risk
    
    The Company is exposed to interest rate risk on its cash and cash equivalents and its debt obligations. Interest income earned on cash and cash equivalents may fluctuate as interest rates change; however, due to their relatively short maturities, the Company does not hedge these assets or their investment cash flows and the impact of interest rate risk is not material. The Company's debt obligations consist of fixed-rate and, from time to time, variable-rate debt instruments. The Company's primary objective is to achieve the lowest overall cost of funding while managing the variability in cash outflows within an acceptable range. In order to achieve this objective, the Company has historically entered into interest rate swap agreements.

    Interest rate swaps involve the periodic exchange of payments without the exchange of underlying principal or notional amounts. Net settlements between the counterparties are recognized as an adjustment to interest expense, net.

    Interest Rate Derivatives – Cash Flow Hedges

    From time to time, the Company has entered into various interest rate lock agreements and forward-starting interest rate swap agreements to hedge part of the Company's interest rate exposure associated with the variability in future cash flows attributable to changes in interest rates.
    
    Interest Rate Derivatives – Fair Value Hedges

    The Company maintains various fixed-to-variable interest rate swaps to convert a portion of the Company's long-term debt into variable interest rate debt.

    A summary of the notional amounts of these interest rate swap agreements as of June 30, 2025 and December 31, 2024 was as follows:
Notional Amount
Debt InstrumentJune 30, 2025December 31, 2024
5.00% Senior Notes due December 2034

2.80% Senior Notes due June 2031
550  
6.40% Senior Notes due November 2033
400  
$1,800 $700 
    The fixed-to-variable interest rate swap agreements in the table above have variable interest rates ranging from SOFR minus 1.36% to SOFR plus 2.48%.
    
    As of June 30, 2025 and December 31, 2024, the following amounts were recorded on the consolidated balance sheets related to cumulative basis adjustments for fair value hedges included in the carrying amount of long-term debt:

    Redeemable Noncontrolling Interest

    In connection with the sale of an 18.9% noncontrolling interest in a subsidiary to UMass on July 1, 2015, the Company granted UMass the right to require the Company to purchase all of its interest in the subsidiary at fair value commencing July 1, 2020. The subsidiary performs diagnostic information services in a defined territory within the state of Massachusetts. Since the redemption of the noncontrolling interest is outside of the Company's control, it has been presented outside of stockholders' equity at the greater of its carrying amount or its fair value. As of June 30, 2025 and December 31, 2024, the redeemable noncontrolling interest was presented at its fair value. For further details regarding the fair value of the redeemable noncontrolling interest, see Note 6.

11.     COMMITMENTS AND CONTINGENCIES

    Letters of Credit

    The Company can issue letters of credit under its Secured Receivables Credit Facility and Senior Unsecured Revolving Credit Facility. For further discussion regarding the facilities, see Note 7 above and Note 13 to the audited consolidated financial statements in the Company's 2024 Annual Report on Form 10-K.
    
    In support of its risk management program, $77 million in letters of credit under the Secured Receivables Credit Facility were outstanding as of June 30, 2025, providing collateral for current and future automobile liability and workers’ compensation loss payments.

    Contingent Lease Obligations
    
    The Company remains subject to contingent obligations under certain real estate leases for which no liability has been recorded. For further details, see Note 18 to the audited consolidated financial statements in the Company’s 2024 Annual Report on Form 10-K.

    Certain Legal Matters

    The Company may incur losses associated with these proceedings and investigations, but it is not possible to estimate the amount of loss or range of loss, if any, that might result from adverse judgments, settlements, fines, penalties, or other resolution of these proceedings and investigations based on the stage of these proceedings and investigations, the absence of specific allegations as to alleged damages, the uncertainty as to the certification of a class or classes and the size of any certified class, if applicable, and/or the lack of resolution of significant factual and legal issues. The Company has insurance coverage rights in place (limited in amount; subject to deductible) for certain potential costs and liabilities related to these proceedings and investigations.
    
    In 2020, two putative class action lawsuits were filed in the U.S. District Court for New Jersey against the Company and other defendants with respect to the Company’s 401(k) plan. The complaint alleges, among other things, that the fiduciaries of the 401(k) plan breached their duties by failing to disclose the expenses and risks of plan investment options, allowing unreasonable administration expenses to be charged to plan participants, and selecting and retaining high cost and poor performing investments. In October 2020, the court consolidated the two lawsuits under the caption In re: Quest Diagnostics ERISA Litigation and plaintiffs filed a consolidated amended complaint. In May 2021, the court denied the Company's motion to dismiss the complaint. After discovery was completed, the Company filed a motion for summary judgment, which was granted. The matter is on appeal.

    On June 3, 2019, the Company reported that Retrieval-Masters Creditors Bureau, Inc./American Medical Collection Agency (“AMCA”) had informed the Company and Optum360 LLC that an unauthorized user had access to AMCA’s system between August 1, 2018 and March 30, 2019 (the “AMCA Data Security Incident”). Optum360 provides revenue management services to the Company, and AMCA provided debt collection services to Optum360. AMCA first informed the Company of the AMCA Data Security Incident on May 14, 2019. AMCA’s affected system included financial information (e.g., credit card numbers and bank account information), medical information and other personal information (e.g., social security numbers). Test results were not included. Neither Optum360’s nor the Company’s systems or databases were involved in the incident. AMCA also informed the Company that information pertaining to other laboratories’ customers was also affected. Following announcement of the AMCA Data Security Incident, AMCA sought protection under the U.S. bankruptcy laws. The bankruptcy proceeding has been dismissed.

    Numerous putative class action lawsuits were filed against the Company related to the AMCA Data Security Incident. The U.S. Judicial Panel on Multidistrict Litigation transferred the cases that were then still pending to, and consolidated them for pre-trial proceedings in, the U.S. District Court for New Jersey. In November 2019, the plaintiffs in the multidistrict proceeding filed a consolidated putative class action complaint against the Company and Optum360 that named additional individuals as plaintiffs and that asserted a variety of common law and statutory claims in connection with the AMCA Data Security Incident. In January 2020, the Company moved to dismiss the consolidated complaint; the motion to dismiss was granted in part and denied in part. Plaintiffs filed an amended complaint, which the Company also moved to dismiss. The motion was granted in part and denied in part. Discovery and class certification proceedings are ongoing.

    In addition, a group of state attorney general offices are investigating the Company in connection with the AMCA Data Security Incident. The Company is cooperating with the investigation.

    The Company is subject to a putative class action entitled Cole, et al. v Quest Diagnostics Incorporated, which was filed in the U. S. District Court for the Eastern District of California, for allegedly conspiring with Facebook to track customers’ internet communications on Company web platforms without authorization, in violation of the California Invasion of Privacy Act ("CIPA") and the California Confidentiality of Medical Information Act ("CMIA"). The complaint alleged that the Company’s actions were an invasion of privacy and contributed to a loss of value in plaintiffs’ personally identifiable information. The Company moved to dismiss the case or, in the alternative, transfer venue to the U.S. District Court for New Jersey. Subsequently, plaintiffs filed an amended complaint, which the Company also moved to dismiss. The Company's motion to transfer the case was granted. The Company refiled its motion to dismiss with the New Jersey District Court. The motion to dismiss was granted without prejudice as to the CMIA claim and denied as to the CIPA claim. Thereafter, the Company filed a motion for reconsideration as to the CIPA claim, which was granted. The matter is on appeal.

    As previously disclosed, in August 2011, the Company had received a subpoena from the U.S. Attorney for the Northern District of Georgia seeking various business records, including records related to the Company's compliance program, certain marketing materials, certain product offerings, and certain test ordering and other policies. The Company cooperated with the request. In 2021, a third amended complaint in a qui tam action filed in the U.S. District Court for the Northern District of Georgia was unsealed, which is related to the matter underlying the August 2011 subpoena. Both the U.S. Department of Justice and the State of Georgia declined to intervene in the action. The Company moved to dismiss the complaint and the complaint was dismissed without prejudice in August 2022. The relator subsequently filed a fourth amended complaint, which the Company has moved to dismiss. On August 23, 2024, the district court dismissed the complaint with prejudice. On appeal, the Eleventh Circuit affirmed the district court's dismissal.

    The Company also received subpoenas from the U.S. Attorney for the District of New Jersey. The subpoenas seek various records relating to the Company’s relationship with the New York Giants and adherence to certain company policies and federal laws. The Company is cooperating with the investigation.

    The Company has also received subpoenas from the New York Attorney General’s Office that seek information about, among other things, the ordering and billing of certain test panels to Medicaid programs in New York. The Company is cooperating with the investigation.

    Other Legal Matters

    In the normal course of business, the Company has been named, from time to time, as a defendant in various legal actions, including arbitrations, class actions and other litigation, arising in connection with the Company's activities as a provider of diagnostic testing, information and services. These actions could involve claims for substantial compensatory and/or punitive damages or claims for indeterminate amounts of damages, and could have an adverse impact on the Company's client base and reputation.

    The Company is also involved, from time to time, in other reviews, investigations and proceedings by governmental agencies regarding the Company's business which may result in adverse judgments, settlements, fines, penalties, injunctions or other relief.

    The federal or state governments may bring claims based on the Company's current practices, which it believes are lawful. In addition, certain federal and state statutes, including the qui tam provisions of the federal False Claims Act, allow private individuals to bring lawsuits against healthcare companies on behalf of government or private payers. The Company is aware of lawsuits, and from time to time has received subpoenas, related to billing or other practices based on the False Claims Act or other federal and state statutes, regulations or other laws. The Company understands that there may be other pending qui tam claims brought by former employees or other "whistleblowers" as to which the Company cannot determine the extent of any potential liability.

    Management cannot predict the outcome of such matters. Although management does not anticipate that the ultimate outcome of such matters will have a material adverse effect on the Company's financial condition, given the high degree of judgment involved in establishing loss estimates related to these types of matters, the outcome of such matters may be material to the Company's consolidated results of operations or cash flows in the period in which the impact of such matters is determined or paid.

    These matters are in different stages. Some of these matters are in their early stages. Matters may involve responding to and cooperating with various government investigations and related subpoenas. As of June 30, 2025, the Company does not believe that material losses related to legal matters are probable.

    Reserves for legal matters totaled $6 million and $4 million as of June 30, 2025 and December 31, 2024, respectively.

    Reserves for General and Professional Liability Claims

    As a general matter, providers of clinical testing services may be subject to lawsuits alleging negligence or other similar legal claims. These suits could involve claims for substantial damages. Any professional liability litigation could also have an adverse impact on the Company's client base and reputation. The Company maintains various liability insurance coverages for, among other things, claims that could result from providing, or failing to provide, clinical testing services, including inaccurate testing results, and other exposures. The Company's insurance coverage limits its maximum exposure on individual claims; however, the Company is essentially self-insured for a significant portion of these claims.

    The Company is subject to a series of individual claims brought by persons in Ireland related to allegations stemming from pap smear screening services performed by the Company. In general, claimants have alleged that the results of certain pap smear screening tests performed by the Company and other providers, pursuant to a program coordinated by the Irish government, were incorrect for individuals who were later diagnosed with cervical cancer. The Irish government and an independent scoping inquiry commissioned by the Irish government found that the Company’s performance of its screening services for the Irish cervical cancer screening program were in accordance with both Ireland’s requirements and international standards. The Company has settled claims made by certain individuals, is a party in multiple lawsuits and may be served as a party in additional lawsuits. The Company does not believe that the resolution of existing or future claims will have a material adverse effect on its financial position or liquidity, but the ultimate outcomes of these claims are unpredictable and subject to significant uncertainties.

    Reserves for general and professional liability claims matters, including those associated with both asserted and incurred but not reported claims, are established on an undiscounted basis by considering actuarially determined losses based upon the Company's historical and projected loss experience. Such reserves totaled $168 million and $169 million as of June 30, 2025 and December 31, 2024, respectively.

    While the basis for claims reserves is actuarially determined losses based upon the Company's historical and projected loss experience, the process of analyzing, assessing and establishing reserve estimates relative to these types of claims involves a high degree of judgment. Although the Company believes that its present reserves and insurance coverage are sufficient to cover currently estimated exposures, it is possible that the Company may incur liabilities in excess of its recorded reserves or insurance coverage. Changes in the facts and circumstances associated with claims could have a material impact on the Company’s results of operations (principally costs of services), cash flows and financial condition in the period that reserve estimates are adjusted or paid.

12.    BUSINESS SEGMENT INFORMATION

    The Company's DIS business is the only reportable segment based on the manner in which the Chief Executive Officer, who is the Company's Chief Operating Decision Maker ("CODM"), assesses performance and allocates resources across the organization. The CODM uses the reported measurement of segment profit (loss) in assessing segment performance versus budget and when deciding how to allocate resources to segments. The DIS business provides diagnostic information services to a broad range of customers within its primary customer channels - physicians, hospitals, and patients and consumers. The DIS business accounted for greater than 97% of net revenues in both 2025 and 2024.

    All other operating segments include the Company's DS businesses, which consist of its risk assessment services and healthcare information technology businesses. The Company's DS businesses offer solutions for insurers and offer solutions for healthcare providers and payers.
        
    As of June 30, 2025, substantially all of the Company’s services were provided within the United States, and substantially all of the Company’s assets were located within the United States. See Note 6 to the audited consolidated financial statements contained in the Company’s 2024 Annual Report on Form 10-K for a discussion of the Company's acquisition of LifeLabs in Canada during August 2024.

    The following table is a summary of segment information for the three and six months ended June 30, 2025 and 2024. Segment asset information is not presented since it is not received by the CODM at the operating segment level. The CODM regularly reviews certain consolidated expenses, including employee compensation costs. "Other segment items" principally consist of costs for obtaining, transporting and testing specimens, facility costs used for the delivery of the Company's services, costs associated with the Company's sales and marketing efforts, and costs related to billing operations. Operating income (loss) of each segment represents net revenues less directly identifiable expenses. General corporate activities included in the table below are comprised of general management and administrative corporate expenses, amortization and impairment of intangibles assets and other operating income and expenses, net of certain general corporate activity costs that are allocated to the DIS and DS businesses. The accounting policies of the segments are the same as those of the Company as set forth in Note 2 to the audited consolidated financial statements contained in the Company’s 2024 Annual Report on Form 10-K and Note 2 to the interim unaudited consolidated financial statements.

13.    REVENUE RECOGNITION

    DIS

    Net revenues in the Company’s DIS business accounted for over 97% of the Company’s total net revenues for the three and six months ended June 30, 2025 and 2024 and are primarily comprised of a high volume of relatively low-dollar transactions. The DIS business, which provides clinical testing services and other services, satisfies its performance obligations and recognizes revenues primarily upon completion of the testing process (when results are reported) or when services have been rendered. The Company estimates the amount of consideration it expects to be entitled to receive from payer customer groups in exchange for providing services using the portfolio approach. These estimates include the impact of contractual allowances (including payer denials), and patient price concessions. The portfolios determined using the portfolio approach consist of the following groups of payer customers: healthcare insurers, government payers (including Medicare and Medicaid programs), client payers and patients.

    For further details regarding revenue recognition in the Company's DIS business, see Note 3 to the audited consolidated financial statements in the Company's 2024 Annual Report on Form 10-K.

Our Company

    Diagnostic Information Services

    Quest Diagnostics works across the healthcare ecosystem to create a healthier world, one life at a time. Our diagnostic information services ("DIS") business provides diagnostic insights from the results of our laboratory testing to empower people, physicians, and organizations to take action to improve health outcomes. Derived from one of the world's largest databases of de-identifiable clinical lab results, our diagnostic insights reveal new avenues to identify and treat disease, inspire healthy behaviors and improve healthcare management. In the right hands and with the right context, our diagnostic insights can inspire actions that transform lives and create a healthier world. We provide services to a broad range of customers within our primary customer channels - physicians (including those associated with accountable care organizations and Federally Qualified Health Centers), hospitals, and patients and consumers. Our other customers include health plans, employers, emerging retail healthcare providers, government agencies, pharmaceutical companies and other commercial clinical laboratories. We offer broad access to clinical testing through a nationwide network of laboratories, patient service centers, phlebotomists in physician offices, and our connectivity resources, including call centers and mobile phlebotomists, nurses and other health and wellness professionals. Our large in-house staff of medical and scientific experts, including medical directors, scientific directors, genetic counselors and board-certified geneticists, provide medical and scientific consultation to healthcare providers and patients regarding our tests and test results, and help them best utilize our services to improve outcomes and enhance satisfaction. Our DIS business makes up greater than 97% of our consolidated net revenues.

    We assess our revenue performance for our DIS business based upon, among other factors, volume (measured by test requisitions) and revenue per requisition. Each test requisition accompanies patient specimens, indicating the test(s) to be performed and the party to be billed for the test(s). Revenue per requisition is impacted by various factors, including, among other items, the impact of fee schedule changes (i.e., unit price), test mix, payer mix, business mix and the number of tests per requisition. Management uses number of requisitions and revenue per requisition data to assist with assessing the growth and performance of the business, including understanding trends affecting number of requisitions, pricing and test mix. Therefore, we believe that information related to changes in these metrics from period to period are useful information for investors as it allows them to assess the performance of the business.

    Diagnostic Solutions

    Our diagnostic solutions ("DS") group, which represents the balance of our consolidated net revenues, includes our risk assessment services business, which offers solutions for insurers, and our healthcare information technology businesses, which offer solutions for healthcare providers and payers.

    For further discussion of the year-over-year changes for the three months ended June 30, 2025 compared to the three months ended June 30, 2024, see "Results of Operations" below.

Invigorate Program
        
    We are engaged in a multi-year program called Invigorate, which includes structured plans to drive savings and improve productivity across the value chain, including in such areas as patient services, logistics and laboratory operations, revenue services, information technology and procurement. The Invigorate program aims to deliver 3% annual cost savings and productivity improvements to partially offset pressures from the current inflationary environment, including labor and benefit cost increases and reimbursement pressures. We are leveraging automation and artificial intelligence to improve productivity and also improve quality across our entire value chain, not just in the laboratory. Other areas of focus include reducing denials and patient concessions, enhancing the digital experience, and selecting and retaining talent.

    For the six months ended June 30, 2025, we incurred $26 million of pre-tax charges in connection with restructuring and integration activities, including $12 million of employee separation costs, with the remainder including integration costs. Most of the charges will result in cash expenditures. Additional restructuring and integration charges may be incurred in future periods, including as we identify additional opportunities to achieve further savings and productivity improvements.

Outlook and Trends

    In July 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted. The OBBBA and other possible legislation is expected to impact healthcare providers in the United States, including us, primarily through changes to Medicaid and the Affordable Care Act (“ACA”). These changes could lead to reduced funding, increased regulatory burdens and potential shifts in patient populations among payer types and utilization. Additional federal and state guidance is expected to be issued in order to implement the various provisions of the OBBBA, many of which have effective dates in 2027 and 2028. In addition, if Congress does not act to extend the enhanced Premium Tax Credits (“PTC”) that were part of the Inflation Reduction Act of 2022, which have helped drive an increase in Individual Public Exchange enrollment, they will expire at the end of 2025 and could also have an impact on patient populations and result in shifts among payer types and utilization.

    Revenues generated under Medicaid and managed Medicaid programs, and through the ACA related Exchange Plans, represented approximately 8% and less than 5%, respectively, of consolidated revenues for 2024. Based on the provisions of the new legislation (including various effective dates), we currently believe that the OBBBA, and expiration of the enhanced PTCs, are not likely to have a material impact on our consolidated revenues for 2025 and 2026. In addition, we currently estimate that for 2026 through 2028 the OBBBA and the planned expiration of the enhanced PTCs at the end of 2025 could reduce our consolidated revenues by up to 50-60 basis points by 2028, compared to 2025, primarily reflecting the impact on our ACA related Exchange Plans revenues.


28

Table of Contents
    While the impacts outlined above represent our current estimates, we continue to assess the impact of the OBBBA and the planned expiration of the enhanced PTCs on our outlook for the remainder of 2025 through 2028.

    The OBBBA also makes permanent key elements of the Tax Cuts and Jobs Act of 2017, including 100% bonus depreciation, domestic research cost expensing and the business interest expense limitation, among other tax changes. Many of the tax provisions of the OBBBA are designed to accelerate tax deductions, which could lead to lower cash tax payments. The new legislation has multiple effective dates, with certain provisions effective in 2025 and others in the future. While we continue to assess the impact of the tax provisions of the OBBBA on our consolidated financial statements, we currently believe that the tax provisions of the legislation are not expected to have a material impact on our statement of operations.

    For additional discussion regarding regulatory trends and uncertainties, and the risk factors that could cause actual results to differ materially from those described above, see Part I, Item 1, “Business – The Clinical Testing Industry,” and “Business – Regulation”, Part I, Item 1A, “Risk Factors” and the “Outlook and Trends” section of Part II, Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our 2024 Annual Report on Form 10-K.    

Critical Accounting Policies
    
    There have been no significant changes to our critical accounting policies from those disclosed in our 2024 Annual Report on Form 10-K.
    
Impact of New Accounting Standards

    The adoption of new accounting standards, if any, is discussed in Note 2 to the interim unaudited consolidated financial statements.

    The impact of recent accounting pronouncements not yet effective on our consolidated financial statements, if any, is also discussed in Note 2 to the interim unaudited consolidated financial statements.

    DIS revenues for the three months ended June 30, 2025 increased by 15.7% compared to the prior year period. For the three months ended June 30, 2025:

The increase in DIS revenues compared to the prior year period was driven primarily by the impact of recent acquisitions and, to a lesser extent, organic growth. For the three months ended June 30, 2025, recent acquisitions contributed approximately 10.3% to DIS revenues.
DIS volume increased by 16.3% compared to the prior year period driven by the impact of recent acquisitions, which contributed approximately 14.2% to DIS volume, with organic volume up by 2.1%.

32

Table of Contents
Total revenue per requisition was down 0.4% versus the prior year period, driven primarily by the impact of the LifeLabs acquisition, which carries a lower revenue per requisition. On an organic basis, revenue per requisition was up 3.3% in the quarter versus the prior year period driven primarily by an increase in the number of tests per requisition and test mix.

    DS revenues for the three months ended June 30, 2025 decreased by 3.1% compared to the prior year period principally due to lower revenues associated with our risk assessment services offered to insurers.
    
    Net revenues for the six months ended June 30, 2025 increased by 13.7% compared to the prior year period. For the six months ended June 30, 2025, organic growth was 3.8% compared to the prior year period.

    DIS revenues for the six months ended June 30, 2025 increased by 14.2% compared to the prior year period. For the six months ended June 30, 2025:

DIS volume increased by 14.3% compared to the prior year period driven by the impact of recent acquisitions, which contributed approximately 13.7% to DIS volume, with organic volume up by 0.6%.
Revenue per requisition was flat compared to the prior year period. The impact of LifeLabs, which has a lower revenue per requisition, was offset by an increase in the number of tests per requisition. On an organic basis, revenue per requisition increased 3.5% during the period.

    DS revenues for the six months ended June 30, 2025 decreased by 5.5% compared to the prior year period principally due to lower revenues associated with our risk assessment services offered to insurers.

    Cost of Services

    Cost of services consists principally of costs for obtaining, transporting and testing specimens as well as facility costs used for the delivery of our services.

    For the three months ended June 30, 2025, cost of services increased by $225 million compared to the prior year period. The increase was primarily driven by the impact of recent acquisitions, wage increases, and, to a lesser extent, higher supplies expense, partially offset by cost savings and productivity improvements from our Invigorate program.

    For the six months ended June 30, 2025, cost of services increased by $419 million compared to the prior year period. The increase was primarily driven by the impact of recent acquisitions, wage increases, and, to a lesser extent, higher supplies expense, partially offset by cost savings and productivity improvements from our Invigorate program.
        
    Selling, General and Administrative Expenses ("SG&A")
    
    SG&A consist principally of the costs associated with our sales and marketing efforts, billing operations, credit loss expense and general management and administrative support as well as administrative facility costs.
    
    For the three months ended June 30, 2025, SG&A increased by $70 million compared to the prior period. The increase was primarily driven by the impact of recent acquisitions, and, to a lesser extent, higher costs associated with changes in the fair value of our deferred compensation obligations.

    For the six months ended June 30, 2025, SG&A increased by $106 million compared to the prior period. The increase was primarily driven by the impact of recent acquisitions, and, to a lesser extent, wage increases.
        
    The changes in the value of our deferred compensation obligations is largely offset by changes in the value of the associated investments, which are recorded in other income, net. For further details regarding our deferred compensation plans, see Note 17 to the audited consolidated financial statements included in our 2024 Annual Report on Form 10-K.

Quantitative and Qualitative Disclosures About Market Risk

    We address our exposure to market risks, principally the risk of changes in interest rates, through a controlled program of risk management that includes the use of derivative financial instruments. We do not hold or issue derivative financial instruments for speculative purposes. We seek to mitigate the variability in cash outflows that result from changes in interest rates by maintaining a balanced mix of fixed-rate and variable-rate debt obligations. In order to achieve this objective, we have historically entered into interest rate swap agreements. Interest rate swap agreements involve the periodic exchange of payments without the exchange of underlying principal or notional amounts. Net settlements are recognized as an adjustment to interest expense, net. We believe that our exposures to foreign exchange impacts and changes in commodity prices are not material to our consolidated results of operations, financial position or cash flows.
    
    As of June 30, 2025 and December 31, 2024, the fair value of our debt was estimated at approximately $5.6 billion and $6.1 billion, respectively, principally using quoted prices in active markets and yields for the same or similar types of borrowings, taking into account the underlying terms of the debt instruments. As of June 30, 2025 and December 31, 2024, the estimated fair value was less than the carrying value of the debt by $26 million and $112 million, respectively. A hypothetical 10% increase in interest rates (representing 47 basis points and 35 basis points as of June 30, 2025 and December 31, 2024, respectively) would potentially reduce the estimated fair value of our debt by approximately $149 million and $184 million, respectively, as of June 30, 2025 and December 31, 2024.

    Borrowings under our secured receivables credit facility and our senior unsecured revolving credit facility are subject to variable interest rates. Interest on our secured receivables credit facility is based on either commercial paper rates for highly-rated issuers or the adjusted Term Secured Overnight Financing Rate ("Term SOFR"), plus a spread. Interest on our senior unsecured revolving credit facility is based on certain published rates plus an applicable margin based on changes in our public debt ratings. As such, our borrowing cost under this credit arrangement is subject to fluctuations in interest rates and changes in our public debt ratings. As of June 30, 2025, the borrowing rates under these debt instruments were: for our secured receivables credit facility, commercial paper rates for highly-rated issuers or the adjusted Term SOFR, plus a spread of 0.80%; and for our senior unsecured revolving credit facility, the adjusted Term SOFR, plus 1.00%. As of June 30, 2025, there were no borrowings outstanding under either the secured receivables credit facility or the senior unsecured revolving credit facility.

    The notional amount of fixed-to-variable interest rate swaps outstanding as of June 30, 2025 and December 31, 2024 was $1.8 billion and $700 million, respectively. The aggregate fair value of the fixed-to-variable interest rate swaps was $17 million and $(34) million, in an asset (liability) position, as of June 30, 2025 and December 31, 2024, respectively.

    Based on our net exposure to interest rate changes, a hypothetical 10% change to the variable rate component of our variable-rate indebtedness would not materially change our annual interest expense. A hypothetical 10% change in the SOFR curve (representing a 36 basis points change in the weighted average yield) would potentially change the fair value of our fixed- to-variable interest rate swaps by $46 million.

    For further details regarding our outstanding debt, see Note 7 to the interim unaudited consolidated financial statements and Note 13 to the audited consolidated financial statements included in our 2024 Annual Report on Form 10-K. For details regarding our financial instruments and hedging activities, see Note 8 to the interim unaudited consolidated financial statements and Note 15 to the audited consolidated financial statements included in our 2024 Annual Report on Form 10-K.

    Risk Associated with Investment Portfolio

    Our investment portfolio primarily includes equity investments comprised mostly of strategic holdings in companies concentrated in the life sciences and healthcare industries. Equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) with readily determinable fair values are measured at fair value in our consolidated balance sheet with changes in fair value recorded in current earnings in our consolidated statement of operations. Equity investments that do not have readily determinable fair values (which consist of investments in preferred and common shares of private companies) are measured at cost minus impairment, if any, plus or minus changes resulting from observable price changes.

    We regularly evaluate equity investments that do not have readily determinable fair values to determine if there are any indicators that the investments are impaired. The carrying value of our equity investments that do not have readily determinable fair values was $36 million as of June 30, 2025. In conjunction with the preparation of our June 30, 2025 financial statements, we considered whether the carrying values of our investments were impaired and concluded that no such impairment existed.

    We do not hedge our equity price risk. The impact of an adverse movement in equity prices on our holdings in privately held companies cannot be easily quantified as our ability to realize returns on investments depends on, among other things, the enterprises’ ability to raise additional capital or derive cash inflows from continuing operations or through liquidity events such as initial public offerings, mergers or private sales.

    Cash and Cash Equivalents

    Cash and cash equivalents consist of cash and highly-liquid short-term investments with original maturities, at the time of acquisition, of three months or less. Cash and cash equivalents as of June 30, 2025 totaled $319 million, compared to $549 million as of December 31, 2024.

    As of June 30, 2025, approximately 29% of our $319 million of consolidated cash and cash equivalents were held outside of the United States.

    Cash Flows from Operating Activities

    Net cash provided by operating activities for the six months ended June 30, 2025 and 2024 was $858 million and $514 million, respectively. The $344 million increase in net cash provided by operating activities for the six months ended June 30, 2025, compared to the prior year period, was primarily a result of increased operating income, the timing of receipts and payments, and the payroll tax credit under the CARES Act.
    
    Days sales outstanding, a measure of billing and collection efficiency, was 47 days as of June 30, 2025, 48 days as of December 31, 2024 and 50 days as of June 30, 2024.

    Cash Flows from Investing Activities

    Net cash used in investing activities for the six months ended June 30, 2025 and 2024 was $239 million and $413 million, respectively. This $174 million decrease in net cash used in investing activities for the six months ended June 30, 2025, compared to the prior year period, was a result of decreased cash used for business acquisitions, partially offset by slightly higher capital expenditures.

    Cash Flows from Financing Activities

    Net cash used in financing activities for the six months ended June 30, 2025 and 2024 was $854 million and $516 million, respectively. This $338 million increase in net cash used in financing activities for the six months ended June 30, 2025, compared to the prior year period, was primarily a result of repaying in full the outstanding indebtedness under our $600 million of 3.50% senior notes at maturity. The six months ended June 30, 2024 included the repayment in full of the outstanding indebtedness under our $300 million of 4.25% senior notes at maturity.

     During the six months ended June 30, 2025, we borrowed $400 million under our secured receivables credit facility, which was repaid prior to June 30, 2025. During the six months ended June 30, 2025, there were no borrowings or repayments under our senior unsecured revolving credit facility. During the six months ended June 30, 2024, there were no borrowings or repayments under our secured receivables credit facility and our senior unsecured revolving credit facility.

    During each of the first and second quarters of 2025, our Board of Directors declared a quarterly cash dividend of $0.80 per common share. During each of the four quarters of 2024, our Board of Directors declared a quarterly cash dividend of $0.75 per common share.
    
    Share Repurchase Program

    As of June 30, 2025, $0.9 billion remained available under our share repurchase authorization. The share repurchase authorization has no set expiration or termination date.

    Share Repurchases

    For both the six months ended June 30, 2025 and 2024, we repurchased no shares of our common stock.

    Contractual Obligations

    A description of the terms of our indebtedness and related debt service requirements is contained in Note 13 to the audited consolidated financial statements included in our 2024 Annual Report on Form 10-K.

    A discussion of our lease obligations is contained in Note 14 to the audited consolidated financial statements included in our 2024 Annual Report on Form 10-K.

    A discussion of our noncancellable commitments to purchase products or services is contained in Note 18 to the audited consolidated financial statements included in our 2024 Annual Report on Form 10-K.

    Equity Method Investees

    Our equity method investees primarily consist of a diagnostic information services joint venture and an investment in a fund that purchases strategic holdings in private companies in the healthcare industry. Such investees are accounted for under the equity method of accounting. Our investment in equity method investees is less than 5% of our consolidated total assets. Our proportionate share of income before income taxes associated with our equity method investees is less than 5% of our consolidated income before income taxes and equity in earnings of equity method investees. We have no material unconditional obligations or guarantees to, or in support of, our equity method investees and their operations.

    In conjunction with the preparation of our June 30, 2025 financial statements, we considered whether the carrying values of our equity method investments were impaired and concluded that no such impairment existed.

    Requirements and Capital Resources

    We estimate that we will invest approximately $500 million during 2025 for capital expenditures, to support and grow our existing operations, principally related to investments in laboratory equipment and facilities, including laboratory automations and information technology to support our diagnostic offerings.

    In February 2025, we committed to a multi-year project ("Project Nova") to modernize our "Order-to-Cash" business processes including related information technology infrastructure and underlying enabling technologies. We expect to deliver value throughout the implementation of Project Nova, as it unlocks a variety of streamlined operational benefits, reduced technology-related operating costs, accelerated revenue opportunities and improvements to the customer and patient experience. See our 2024 Annual Report on Form 10-K for further details.

    We have $500 million of 3.45% senior notes due June 2026.
    
    As of June 30, 2025, we had $1.3 billion of borrowing capacity available under our existing credit facilities, including $523 million available under our secured receivables credit facility and $750 million available under our senior unsecured revolving credit facility. There were no borrowings outstanding under either the secured receivables credit facility or the senior unsecured revolving credit facility as of June 30, 2025. In support of our risk management program, $77 million in letters of credit under the secured receivables credit facility were outstanding as of June 30, 2025.

    Our secured receivables credit facility is subject to customary affirmative and negative covenants, and certain financial covenants with respect to the receivables that comprise the borrowing base and secure the borrowings under the facility. Our

senior unsecured revolving credit facility is also subject to certain financial covenants and limitations on indebtedness. As of June 30, 2025, we were in compliance with all such applicable financial covenants.

    We believe that our cash and cash equivalents and cash from operations, together with our borrowing capacity under our credit facilities, will provide sufficient financial flexibility to fund seasonal and other working capital requirements, capital expenditures, debt service requirements and other obligations, cash dividends on common shares, share repurchases and additional growth opportunities, including acquisitions, for the foreseeable future. However, should it become necessary, we believe that our credit profile should provide us with access to additional financing in order to fund normal business operations, make interest payments, fund additional growth opportunities, including acquisitions, and satisfy upcoming debt maturities.
