During fiscal 2024, sales to the Company’s ten largest customers, including group purchasing organizations (“GPOs”), accounted for approximately 69% of its total consolidated revenues and approximately 43% of total trade accounts receivable at March 31, 2024. Sales to the Company’s largest customer, CVS Health Corporation (“CVS”), accounted for approximately 28% of its total consolidated revenues in fiscal 2024 and comprised approximately 24% of total trade accounts receivable at March 31, 2024. As a result, the Company’s sales and credit concentration is significant. The Company has agreements with GPOs, each of which functions as a purchasing agent on behalf of member hospitals, pharmacies, and other healthcare providers, as well as with government entities and agencies. The accounts receivable balances are with individual members of the GPOs, and therefore no significant concentration of credit risk exists. A material default in payment, a material reduction in purchases from GPOs or any other large customers, or the loss of a large customer or customer groups could have a material adverse impact on the Company’s financial condition, results of operations, and liquidity. In addition, trade accounts receivables are subject to concentrations of credit risk with customers in the institutional, retail, and healthcare provider sectors, which can be affected by a downturn in the economy, changes in reimbursement policies, and other factors. This credit risk is mitigated by the size and diversity of the Company’s customer base as well as its geographic dispersion.</span></div>
