Trends and Uncertainties:

Opioid-Related Litigation and Claims

As described in the discussion of opioid-related matters in Financial Note 17, “Commitments and Contingent Liabilities,” to the consolidated financial statements included in this Annual 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. Other than as to the settlements described in Financial Note 17, “Commitments and Contingent Liabilities,”, 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.

Rite Aid Bankruptcy Proceedings

During fiscal 2024, 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. As a result, we recorded a provision for bad debts of $725 million for the year ended March 31, 2024, representing the uncollected trade accounts receivable from sales to Rite Aid 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 year ended March 31, 2025, 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 $206 million recorded within “Selling, distribution, general, and administrative expenses” in our Consolidated Statements of Operations and included within our U.S. Pharmaceutical segment. During the year ended March 31, 2025, 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 Consolidated Balance Sheet. On May 5, 2025, Rite Aid filed a second voluntary petition under Chapter 11 of the Bankruptcy Code.

We believe the reserves maintained and any adjustments recorded 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 included in this Financial Review.
