CVS HEALTH Corp

Endnotes

(1)The Company defines adjusted operating income as operating income (loss) (GAAP measure) excluding the impact of amortization of intangible assets, net realized capital gains or losses and other items, if any, that neither relate to the ordinary course of the Company’s business nor reflect the Company’s underlying business performance, such as acquisition-related integration costs, the Omnicare guarantee, goodwill impairment charges, Health Care Delivery clinic closure charges, opioid litigation charges, certain legacy litigation charges, losses on Accountable Care assets and office real estate optimization charges. The chief operating decision maker (the “CODM”) uses adjusted operating income as its principal measure of segment performance as it enhances the CODM’s ability to compare past financial performance with current performance and analyze underlying business performance and trends. The consolidated measure is not determined in accordance with GAAP and should not be considered a substitute for, or superior to, the most directly comparable GAAP measure, consolidated operating income (loss). See “Non-GAAP Financial Information” earlier in this press release for additional information regarding the items excluded from consolidated operating income (loss) in determining consolidated adjusted operating income.

(2)GAAP diluted earnings (loss) per share and Adjusted EPS, respectively, are calculated by dividing net income (loss) attributable to CVS Health and adjusted income attributable to CVS Health by the Company’s weighted average diluted shares outstanding. The Company defines adjusted income attributable to CVS Health as net income (loss) attributable to CVS Health (GAAP measure) excluding the impact of amortization of intangible assets, net realized capital gains or losses and other items, if any, that neither relate to the ordinary course of the Company’s business nor reflect the Company’s underlying business performance, such as acquisition-related integration costs, the Omnicare guarantee, goodwill impairment charges, Health Care Delivery clinic closure charges, opioid litigation charges, certain legacy litigation charges, losses on Accountable Care assets, office real estate optimization charges, the gain on deconsolidation of subsidiary, as well as the corresponding income tax benefit or expense related to the items excluded from adjusted income attributable to CVS Health. Adjusted EPS for the three and nine months ended September 30, 2025 is calculated utilizing weighted average diluted shares outstanding, which include potential common shares in each period, as the impact of the potential common shares was dilutive. The potential common shares were excluded from the calculations of GAAP loss per share for the three and nine months ended September 30, 2025, as the shares would have had an anti-dilutive effect as a result of the GAAP net loss in each period. See “Non-GAAP Financial Information” earlier in this press release for additional information regarding the items excluded from net income (loss) attributable to CVS Health in determining adjusted income attributable to CVS Health.

(3) Medical benefit ratio is calculated by dividing the Health Care Benefits segment’s health care costs by premium revenues and represents the percentage of premium revenues spent on medical benefits for the segment’s insured members. Management uses MBR to assess the underlying business performance and underwriting of its insurance products, understand variances between actual results and expected results and identify trends in period-over-period results. MBR provides management and investors with information useful in assessing the operating results of the Health Care Benefits segment’s insured products.

(4) Medical membership represents the number of members covered by the Health Care Benefits segment’s insured and ASC medical products and related services at a specified point in time. Management uses this metric to understand variances between actual medical membership and expected amounts as well as trends in period-over-period results. This metric provides management and investors with information useful in understanding the impact of medical membership on the Health Care Benefits segment’s total revenues and operating results.

(5) Pharmacy claims processed represents the number of prescription claims processed through the Company’s pharmacy benefits manager and dispensed by either its retail network pharmacies or the Company’s mail and specialty pharmacies. Prescriptions filled represents the number of prescriptions dispensed through the Pharmacy & Consumer Wellness segment’s retail pharmacies and infusion services operations, as well as through the Omnicare long-term care pharmacies prior to their deconsolidation in September 2025. Management uses these metrics to understand variances between actual claims processed and prescriptions dispensed, respectively, and expected amounts as well as trends in period-over-period results. These metrics provide management and investors with information useful in understanding the impact of pharmacy claim volume and prescription volume, respectively, on segment total revenues and operating results.

(6)Includes an adjustment to convert 90-day prescriptions to the equivalent of three 30-day prescriptions. This adjustment reflects the fact that these prescriptions include approximately three times the amount of product days supplied compared to a normal prescription.

(7)Days claims payable is calculated by dividing the Health Care Benefits segment’s health care costs payable at the end of each quarter by its average health care costs per day during such quarter. Management and investors use this metric as one of the indicators of the adequacy of the health care costs payable liability at the end of each quarter.

(8) Gross profit is calculated as the segment’s total revenues less its cost of products sold, and, for the Health Services segment, health care costs. Gross margin is calculated by dividing the segment’s gross profit by its total revenues and represents the percentage of total revenues that remains after incurring direct costs associated with the segment’s products sold and services provided. Gross margin provides investors with information that may be useful in assessing the operating results of the Company’s Health Services and Pharmacy & Consumer Wellness segments.

(9) Same store sales and prescription volume represent the change in revenues and prescriptions filled in the Company’s retail pharmacy stores that have been operating for greater than one year and digital sales initiated online or through mobile applications and fulfilled through the Company’s distribution centers, expressed as a percentage that indicates the increase or decrease relative to the comparable prior period. Same store metrics exclude revenues and prescriptions from infusion services operations and long-term care pharmacies. Management uses these metrics to evaluate the performance of existing stores on a comparable basis and to inform future decisions regarding existing stores and new locations. Same-store metrics provide management and investors with information useful in understanding the portion of current revenues and prescriptions resulting from organic growth in existing locations versus the portion resulting from opening new stores.
