Trends and Uncertainties:

Opioid-Related Litigation and Claims

As described in the discussion of opioid-related matters in Financial Note 10, “Commitments and Contingent Liabilities,” to the condensed consolidated financial statements accompanying this Quarterly Report, we are a defendant in many legal proceedings asserting claims related to the distribution of controlled substances (opioids) in federal and state courts throughout the U.S., and in Puerto Rico and Canada. The plaintiffs in these actions have included state attorneys general, county and municipal governments, tribal nations, hospitals, health and welfare funds, third-party payors, and individuals. We believe we have valid legal defenses in all opioid-related matters, including claims not covered by settlement agreements, and we intend to mount a vigorous defense. Other than as to the settlements described in Financial Note 10, we have not concluded a loss is probable in any of the matters; nor is any possible loss or range of loss reasonably estimable. An adverse judgment or negotiated resolution in any of these matters could have a material adverse impact on our financial position, cash flows or liquidity, or results of operations.

During the nine months ended December 31, 2024, we made payments totaling $500 million associated with various settlement agreements for opioid-related claims of states, subdivisions, and Native American tribes. Our total estimated liability for opioid-related claims was $6.4 billion as of December 31, 2024, of which $775 million was included within “Other accrued liabilities” for the amount estimated to be paid within the next twelve months, and the remaining liability was included in “Long-term litigation liabilities” in our Condensed Consolidated Balance Sheet.

Rite Aid Bankruptcy Proceedings

In October 2023, our customer Rite Aid Corporation (including certain of its subsidiaries, “Rite Aid”) filed a voluntary petition for reorganization under Chapter 11 of the Bankruptcy Code. Consequently, during the second quarter of fiscal 2024, we recorded a provision for bad debts of $210 million, which represented the uncollected trade accounts receivable balance as of September 30, 2023 due from Rite Aid. During the nine months ended December 31, 2023, we recorded a provision for bad debts totaling $725 million, of which $515 million was recorded in the third quarter of fiscal 2024 representing the uncollected trade accounts receivable from sales to Rite Aid through October 2023 prior to its bankruptcy petition filing.

Rite Aid's restructuring plan was approved by the court and the company successfully emerged from bankruptcy in August 2024. During the nine months ended December 31, 2024, we reassessed our initial estimates made in conjunction with the previously reserved prepetition balances, including cash received during the period, resulting in a reversal of $203 million recorded within “Selling, distribution, general, and administrative expenses” in our Condensed Consolidated Statements of Operations and included in our U.S. Pharmaceutical segment. During the nine months ended December 31, 2024, we released $237 million of allowance for doubtful accounts against trade accounts receivables, representing the write-off of uncollectible receivables related to the Rite Aid provision in the Condensed Consolidated Balance Sheet.

We believe the reserves maintained and expenses and credits recorded in fiscal 2025 and fiscal 2024 for Rite Aid trade accounts receivable are appropriate and consistent with our accounting policy and assessment of the information currently available. We evaluate our reserves periodically and as circumstances warrant which may result in changes to our reserves. For additional disclosure of our policy regarding allowances for credit losses, refer to the “Critical Accounting Estimates” section within Item 7 - Management’s Discussion and Analysis of Financial Condition and Results of Operations in Part II of our 2024 Annual Report.
