ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

For discussion of 2023 items and year-over-year comparisons between 2024 and 2023 that are not included in this 2025 Form 10-K, refer to "Item 7. – Management Discussion and Analysis of Financial Condition and Results of Operations" found in our Form 10-K for the year ended December 31, 2024, that was filed with the Securities and Exchange Commission on February 20, 2025.

Executive Overview

General

Our industry relies on two key statistics to measure performance. The benefit ratio, which is computed by taking total benefits expense as a percentage of premiums revenue, represents a statistic used to measure underwriting profitability. The operating cost ratio, which is computed by taking total operating costs, excluding depreciation and amortization, as a percentage of total revenue less investment income, represents a statistic used to measure administrative spending efficiency.

Employer Group Commercial Medical Products Business Exit

During 2025, we finalized our exit from the Employer Group Commercial Medical Products business, which included all fully insured, self-funded and Federal Employee Health Benefit medical plans, as well as associated wellness and rewards programs. No other Humana health plan offerings were materially affected. Following a strategic review, we determined the Employer Group Commercial Medical Products business was no longer positioned to sustainably meet the needs of commercial members over the long term or support our long-term strategic plans.

Value Creation Initiatives and Impairment Charges

In order to create capacity to fund growth in our businesses, we committed to drive additional value for the enterprise through cost saving and productivity initiatives. In addition, in response to sustained macroeconomic, regulatory and competitive pressures impacting the industry, we initiated a substantial multi-year transformation program designed to re-align our cost structure, operating model and technology footprint with evolving market conditions.

As a result of these initiatives, we recorded charges of $449 million, $281 million and $436 million in 2025, 2024 and 2023, respectively, primarily within operating costs in the consolidated statements of income. We expect to incur additional charges over the course of the program.

The value creation initiative charges primarily relate to $329 million, $25 million and $199 million in severance and other employee related charges in connection with workforce optimization in 2025, 2024 and 2023, respectively, as well as $40 million, $256 million and $237 million in asset impairments in 2025, 2024 and 2023, respectively. The remainder of the 2025 charges primarily relate to external consulting spend.

In addition, we recorded impairment charges of $253 million, $200 million and $91 million in 2025, 2024 and 2023, respectively. The impairment charges included impairment of indefinite-lived intangible assets for $128 million, $200 million and $55 million in 2025, 2024 and 2023, respectively, included within operating costs in our consolidated statements of income. The remaining impairment charges were included within investment income in our consolidated statements of income.

In addition to the value creation initiatives, we also recorded severance charges of $70 million in 2023 within operating costs in our consolidated statement of income as a result of our exit from the Employer Group Commercial Medical Products business.

Business Segments

Our tworeportable segments, Insurance and CenterWell, are based on a combination of the type of health plan customer and adjacent businesses centered on well-being solutions for our health plans and other customers, as described below. Our Chief Executive Officer, the Chief Operating Decision Maker, utilizes these segment groupings and results of each segment, measured by income (loss) from operations, to assess performance and allocate resources primarily during our annual budget process and periodic forecast updates. For segment financial information, refer to Note 18 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

The Insurance segment consists of Medicare benefits, marketed to individuals or directly via group Medicare accounts, as well as our contract with CMS to administer the Limited Income Newly Eligible Transition, or LI-NET, prescription drug plan program and contracts with various states to provide Medicaid, dual eligible demonstration, and Long-Term Support Services benefits, which we refer to collectively as our state-based contracts. This segment also includes products consisting of specialty health insurance benefits marketed to individuals and employer groups, including dental, vision, and other supplemental health benefits. In addition, our Insurance segment includes our Military services business, primarily our T-5 East Region contract, as well as the operations of our PBM business.

The CenterWell segment includes our pharmacy solutions, primary care, and home solutions operations. Services offered by this segment are designed to enhance the overall healthcare experience. These services may lead to lower utilization associated with improved member health and/or lower drug costs.

Transactions between reportable segments primarily consist of sales of products and services rendered by our CenterWell segment, primarily pharmacy solutions, primary care, and home solutions, to our Insurance segment customers. Intersegment sales and expenses are recorded primarily at fair value and eliminated in consolidation. Members served by our segments often use the same provider networks, enabling us in some instances to obtain more favorable contract terms with providers. Our segments also share indirect costs and assets. As a result, the profitability of each segment is interdependent. We allocate most operating expenses to our segments. Assets and certain corporate income and expenses are not allocated to the segments, including the portion of investment income not supporting segment operations, interest expense on corporate debt, and certain other corporate expenses. These items are managed at a corporate level. These corporate amounts are reported separately from our reportable segments and are included with intersegment eliminations.

Seasonality

Our Medicare benefit costs rise as members pay their contractual portion of claims responsibility, progress through their annual deductible and maximum out-of-pocket expenses, as well as incurring higher episodic cost of care resulting in a higher benefit ratio throughout the year.

Our quarterly Insurance segment earnings and operating cash flows are impacted by the Medicare Part D benefit design and changes in the composition of our stand-alone prescription drug plan, or PDP, membership. The Medicare Part D benefit design results in coverage that varies as a member’s cumulative out-of-pocket costs pass through successive stages of a member’s plan period, which begins annually on January 1 for renewals. Effective January 1, 2025, the Medicare Part D coverage gap was eliminated as mandated by the Inflation Reduction Act of 2022, or IRA. The benefit design changes reduced out-of-pocket costs for beneficiaries, resulting in greater cost sharing and a leveling of net prescription costs throughout the year as compared to the historical seasonal decline prior to the IRA. In addition, the number of low income senior members as well as year-over-year changes in the mix of membership in our stand-alone PDP products affects the quarterly benefit ratio pattern.

The Insurance segment also experiences seasonality in the operating cost ratio as a result of costs incurred in the second half of the year associated with the Medicare marketing season.

Highlights

•Our strategy is to offer our members affordable health care combined with a positive consumer experience in growing markets. At the core of this strategy is our integrated care delivery model, which unites quality care, high member engagement, and sophisticated data analytics. Our approach to primary, physician-directed care for our members aims to provide quality care that is consistent, integrated, cost-effective, and member-focused, provided by both employed physicians and physicians with network contract arrangements. The model is designed to improve health outcomes and affordability for individuals and for the health system as a whole, while offering our members a simple, seamless healthcare experience. We believe this strategy is positioning us for long-term growth in both membership and earnings. We offer providers a continuum of opportunities to increase the integration of care and offer assistance to providers in transitioning from a fee-for-service to a value-based arrangement. These include performance bonuses, shared savings and shared risk relationships. At December 31, 2025, approximately 3,586,100 members, or 68%, of our individual Medicare Advantage members were in value-based relationships under our integrated care delivery model, as compared to 3,994,300 members, or 71%, at December 31, 2024.

•Net income attributable to Humana was $1.2 billion, or $9.84 per diluted common share, and $1.2 billion, or $9.98 per diluted common share, in 2025 and 2024, respectively. This comparison was significantly impacted by put/call valuation adjustments associated with non-consolidating minority interest investments, charges associated with value creation initiatives, impairment charges, loss on sale of business and settlement of certain litigation expenses. The impact of these adjustments to our consolidated income before income taxes and equity in net earnings and diluted earnings per common share was as follows for the 2025 and 2024 periods:

(in millions)

Consolidated income before income taxes and equity in net losses:

Value creation initiatives 449 281

Loss on sale of business 67 —

Settlement of certain litigation expenses 15 —

Value creation initiatives 3.72 2.33

Loss on sale of business 0.55 —

Settlement of certain litigation expenses 0.13 —

Cumulative net tax impact (3.36) (1.50)

Regulatory Environment

We are and will continue to be regularly subject to new laws and regulations, changes to existing laws and regulations, and judicial determinations that impact the interpretation and applicability of those laws and regulations. The Health Care Reform Law, the Families First Act, the CARES Act, and the Inflation Reduction Act, and related regulations, are examples of laws which haveenacted significant reforms to various aspects of the U.S. health insurance industry, including, among others, mandated coverage requirements, mandated benefits and guarantee issuance associated with insurance products, rebates to policyholders based on minimum benefit ratios, adjustments to Medicare Advantage premiums, the establishment of federally facilitated or state-based exchanges coupled with programs designed to spread risk among insurers, and the introduction of plan designs based on set actuarial values, and changes to the Part D prescription drug benefit design.

It is reasonably possible that these laws and regulations, as well as other current or future legislative, judicial or regulatory changes including restrictions on our ability to manage our provider network, manage and sell our products, or otherwise operate our business, or restrictions on profitability, including reviews by regulatory bodies that may compare our Medicare Advantage profitability to our non-Medicare Advantage business profitability, or compare the profitability of various products within our Medicare Advantage business, and require that they remain within certain ranges of each other, increases in member benefits or changes to member eligibility criteria without corresponding increases in premium payments to us, further restrictions on service arrangements and fee payments between intercompany or vertically-integrated assets, increases in regulation of our prescription drug benefit businesses, reductions in reimbursement rates, or changes to the Part D prescription drug benefit design (and uncertainty arising from the implementation of these changes) in the aggregate may have a material adverse effect on our results of operations (including restricting revenue, enrollment and premium growth in certain products and market segments, restricting our ability to expand into new markets, increasing our medical and operating costs, further lowering our Medicare payment rates and increasing our expenses associated with assessments); our financial position (including our ability to maintain the value of our goodwill); and our cash flows.

We intend for the discussion of our financial condition and results of operations that follows to assist in the understanding of our financial statements and related changes in certain key items in those financial statements from year to year, including the primary factors that accounted for those changes. Transactions between reportable segments primarily consist of sales of products and services rendered by our CenterWell segment, primarily pharmacy solutions, primary care, and home solutions, to our Insurance segment customers and are described in Note 18 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

Comparison of Results of Operations for 2025 and 2024

The following discussion primarily details our results of operations for the year ended December 31, 2025, or the 2025 period, and the year ended December 31, 2024, or the 2024 period.

(a)Represents total benefits expense as a percentage of premiums revenue.

(b)Represents total operating costs, excluding depreciation and amortization, as a percentage of total revenues less investment income.

Premiums Revenue

Consolidated premiums revenue increased $10.7 billion, or 9.6%, from $112.1 billion in the 2024 period to $122.8 billion in the 2025 period primarily due to higher per member Medicare premiums, largely driven by an increased direct subsidy due to the IRA, and higher per member state-based contracts premiums, as well as membership growth in the state-based contracts and stand-alone PDP businesses. These factors were partially offset by the membership decline within the individual Medicare Advantage business, inclusive of the decision to exit certain unprofitable plans and counties in 2025.

Services Revenue

Consolidated services revenue increased $1.4 billion, or 31.6%, from $4.4 billion in the 2024 period to $5.8 billion in the 2025 period primarily due to higher revenues associated with external growth in the primary care and pharmacy solutions businesses, partially offset by the impact of the v28 risk model revision impacting the primary care business.

Investment Income

Investment income decreased $0.2 billion, or 17.9%, from $1.2 billion in the 2024 period to $1.0 billion in the 2025 period primarily due to lower interest income on our debt securities, as well as non-cash impairment charge in the fourth quarter of 2025 related to our minority ownership interest in a joint-venture investment, deemed unrecoverable based on recent market activity.

Benefits Expense

Consolidated benefits expense increased $10.1 billion, or 10.1%, from $100.7 billion in the 2024 period to $110.8 billion in the 2025 period. The consolidated benefit ratio increased 40 basis points from 89.8% in the 2024 period to 90.2% in the 2025 period primarily due to a shift in line of business mix resulting from growth in the state-based contracts and stand-alone PDP businesses that carry a higher benefit ratio, combined with a reduction in individual Medicare Advantage membership, incremental investments to improve member and patient outcomes and support operational excellence, and the year-over-year increase in the Medicare stand-alone PDP benefit ratio driven by the impact of the IRA. These factors were partially offset by individual Medicare Advantage pricing inclusive of plan exits and benefit design changes that more than offset claims trend and the funding environment, as well as the anticipated higher favorable prior-period medical claims development in the 2025 period.

Consolidated benefits expense included $1.0 billion of favorable prior-period medical claims reserve development in the 2025 period and $701 million of favorable prior-period medical claims reserve development in the 2024 period. Prior-period medical claims reserve development decreased the consolidated benefit ratio by approximately 80 basis points in the 2025 period and decreased the consolidated benefit ratio by approximately 60 basis points in the 2024 period. Prior-period medical claims reserve development excludes the effects of provider risk-sharing arrangements, which are accounted for separately based on contractual settlement terms.

Operating Costs

Our segments incur both direct and shared indirect operating costs. We allocate the indirect costs shared by the segments primarily as a function of revenues. As a result, the profitability of each segment is interdependent.

Consolidated operating costs increased $1.8 billion, or 12.8%, from $13.7 billion in the 2024 period to $15.5 billion in the 2025 period. The consolidated operating cost ratio increased 20 basis points from 11.8% in the 2024 period to 12.0% in the 2025 period primarily due to business mix changes, including within the CenterWell segment that runs a significantly higher operating cost ratio than the Insurance segment, the operating leverage impact associated with the loss of individual Medicare Advantage membership, as well as higher charges associated with the value creation plan. These factors were partially offset by administrative cost efficiencies resulting from the value creation initiatives, operating leverage associated with increased revenues from the impact of the IRA, and a lesser operating cost impact from impairment costs in the 2025 period compared to the 2024 period.

Depreciation and Amortization

Depreciation and amortization decreased $141 million, or 16.8%, from $839 million in the 2024 period to $698 million in the 2025 period primarily due to decreased capital spending.

Interest Expense

Interest expense decreased $29 million, or 4.4%, from $660 million in the 2024 period to $631 million in the 2025 period primarily due to decrease in interest rates and average debt balances.

Income Taxes

Our effective tax rate was 17.4% and 25.5% for the 2025 period and 2024 period, respectively. The 2025 period effective income tax rate reflects the impact of a tax loss on sale of business, which exceeded the book loss. The related tax benefit is realizable via capital loss carryback. For a complete reconciliation of the federal statutory rate to the effective tax rate, refer to Note 12 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

Income from operations

Insurance segment income from operations increased $0.4 billion, or 29.1%, from $1.3 billion in the 2024 period to $1.7 billion in the 2025 period primarily due to the same factors impacting the Insurance segment's benefit and operating cost ratios as more fully described below.

Enrollment

Individual Medicare Advantage membership decreased 412,500 members, or 7.3%, from 5,661,800 members as of December 31, 2024 to 5,249,300 members as of December 31, 2025 inclusive of the decision to exit certain unprofitable plans and counties in 2025. Individual Medicare Advantage membership includes 760,500 D-SNP members as of December 31, 2025, a net decrease of 176,600 D-SNP members, or 18.8%, from 937,100 members as of December 31, 2024. For the full year 2026, we anticipate net membership growth in our individual Medicare Advantage offerings of approximately 25%.

Group Medicare Advantage membership increased 22,700 members, or 4.2%, from 545,700 members as of December 31, 2024 to 568,400 members as of December 31, 2025 consistent with expectations as we maintain pricing discipline in a competitive market. For the full year 2026, we anticipate net membership growth in our group Medicare Advantage offerings of approximately 150,000 members.

Medicare stand-alone PDP membership increased 174,400 members, or 7.6%, from 2,288,200 members as of December 31, 2024 to 2,462,600 members as of December 31, 2025 reflecting shifting competitive dynamics. For the full year 2026, we anticipate net membership growth in our Medicare stand-alone PDP offerings of approximately 1,000,000 members.

State-based contracts and other membership increased 155,700 members, or 10.7%, from 1,459,900 members as of December 31, 2024 to 1,615,600 members as of December 31, 2025 primarily due to the Virginia contract implemented in 2025 and the allocation of additional membership in Kentucky. For the full year 2026, we anticipate net membership growth in our state-based contracts of in a range of 25,000 to 100,000 members.

Specialty membership increased 180,600 members, or 4.0%, from 4,562,000 members as of December 31, 2024 to 4,742,600 members as of December 31, 2025 primarily reflecting growth in group dental and vision products.

Premiums revenue

Insurance segment premiums revenue increased $10.7 billion, or 9.6%, from $112.1 billion in the 2024 period to $122.8 billion in the 2025 period primarily due to higher per member Medicare premiums, largely driven by an increased direct subsidy due to the IRA, and higher per member state-based contracts premiums, as well as membership growth in the state-based contracts and stand-alone PDP businesses. These factors were partially offset by the membership decline within the individual Medicare Advantage business, inclusive of the decision to exit certain unprofitable plans and counties in 2025.

Services revenue

Insurance segment services revenue increased $0.1 billion, or 5.3%, from $966 million in the 2024 period to $1 billion in the 2025 period.

Benefits expense

The Insurance segment benefit ratio was unchanged at 90.4% in the 2024 and 2025 periods primarily due to a shift in line of business mix resulting from growth in the state-based contracts and stand-alone PDP businesses that carry a higher benefit ratio, combined with a reduction in individual Medicare Advantage membership, incremental investments to improve member and patient outcomes and support operational excellence, and the year-over-year increase in the Medicare stand-alone PDP benefit ratio driven by the impact of the IRA. These factors were offset by individual Medicare Advantage pricing inclusive of plan exits and benefit design changes that more than offset claims trend and the funding environment, as well as the anticipated higher favorable prior-period medical claims development in the 2025 period.

The Insurance segment benefits expense included $1.0 billion of favorable prior-period medical claims reserve development in the 2025 period and $701 million of favorable prior-period medical claims reserve development in the 2024 period. Prior-period medical claims reserve development decreased the Insurance segment benefit ratio by approximately 80 basis points in the 2025 period and decreased the Insurance segment benefit ratio by

approximately 60 basis points in the 2024 period. Prior-period medical claims reserve development excludes the effects of provider risk-sharing arrangements, which are accounted for separately based on contractual settlement terms.

Operating costs

The Insurance segment operating cost ratio decreased 10 basis points from 9.2% in the 2024 period to 9.1% in the 2025 period primarily due to administrative cost efficiencies resulting from the value creation initiatives and operating leverage associated with increased revenues from the impact of the IRA. These factors were partially offset by the operating leverage impact associated with the loss of individual Medicare Advantage membership.

Income from operations

CenterWell income from operations was relatively unchanged at $1.3 billion in the 2024 and 2025 periods, reflecting the same factors impacting the CenterWell segment's revenue and operating cost ratio as more fully described below.

Services revenue

CenterWell services revenue increased $1.4 billion, or 39.0%, from $3.5 billion in the 2024 period to $4.8 billion in the 2025 period primarily due to higher revenues associated with growth in the primary care and pharmacy solutions businesses, partially offset by the impact of the v28 risk model revision impacting the primary care business.

Intersegment revenues

CenterWell intersegment revenues increased $1.2 billion, or 7.2%, from $16.5 billion in the 2024 period to $17.7 billion in the 2025 period primarily due to higher revenues associated with growth in the pharmacy solutions business.

Operating costs

The CenterWell segment operating cost ratio increased 90 basis points from 92.2% in the 2024 period to 93.1% in the 2025 period primarily resulting from the continued phase-in of the v28 risk model revision within the primary care business, as well as the uptick of volume within CenterWell Specialty Pharmacy that carries a higher operating cost ratio than the traditional pharmacy business. These factors were partially offset by continued maturation of the v28 mitigation activities within the primary are business and administrative cost efficiencies resulting from the value creation initiatives.

Liquidity

Historically, our primary sources of cash have included receipts of premiums, services revenue, and investment and other income, as well as proceeds from the sale or maturity of our investment securities, and borrowings. Our primary uses of cash historically have included disbursements for claims payments, operating costs, interest on

borrowings, taxes, purchases of investment securities, acquisitions, capital expenditures, repayments on borrowings, dividends, and share repurchases. As premiums generally are collected in advance of claim payments by a period of up to several months, our business normally should produce positive cash flows during periods of increasing premiums and enrollment. Conversely, cash flows would be negatively impacted during periods of decreasing premiums and enrollment. From period to period, our cash flows may also be affected by the timing of working capital items including premiums receivable, benefits payable, and other receivables and payables. Our cash flows are impacted by the timing of payments to and receipts from CMS associated with Medicare Part D subsidies for which we do not assume risk. The use of cash flows may be limited by regulatory requirements of state departments of insurance (or comparable state regulators) which require, among other items, that our regulated subsidiaries maintain minimum levels of capital and seek approval before paying dividends from the subsidiaries to the parent. Our use of cash flows derived from our non-insurance subsidiaries, such as in our CenterWell segment, is generally not restricted by state departments of insurance (or comparable state regulators).

For additional information on our liquidity risk, please refer to Part I, Item 1A, "Risk Factors" of this Form 10-K.

Cash and cash equivalents increased to $4.2 billion at December 31, 2025 from $2.2 billion at December 31, 2024. The change in cash and cash equivalents for the years ended December 31, 2025, 2024 and 2023 is summarized as follows:

(in millions)

Net cash provided by operating activities $ 921 $ 2,966 $ 3,981

Net cash provided by (used in) investing activities 2,273 (2,952) (3,492)

Net cash used in financing activities (1,215) (2,487) (856)

Increase (decrease) in cash and cash equivalents $ 1,979 $ (2,473) $ (367)

Cash Flow from Operating Activities

Cash flows provided by operations of $0.9 billion in the 2025 period decreased $2.0 billion from cash flows provided by operations of $3.0 billion in the 2024. The decrease in our operating cash flows primarily reflected timing impacts, including the year-over-year increase in receivables due to the IRA and the unfavorable impact of working capital items.

The most significant drivers of changes in our working capital are typically the timing of payments of benefits expense and receipts for premiums. Benefits expense includes claim payments, capitation payments, pharmacy costs net of rebates, allocations of certain centralized expenses and various other costs incurred to provide health insurance coverage to members, as well as estimates of future payments to hospitals and others for medical care and other supplemental benefits provided on or prior to the balance sheet date. For additional information regarding our benefits payable and benefits expense recognition, refer to Note 2 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

Change in receivables per cash flow statement $ 570 $ 669

The changes in Medicare receivables for the 2025 period reflects higher per member Medicare premiums, partially offset by lower individual Medicare Advantage membership. The change in Medicare receivables for the 2024 period reflects individual Medicare Advantage membership growth. In addition, both periods further reflect the typical pattern caused by the timing of accruals and related collections associated with the CMS risk-adjustment model. Significant collections occur with the mid-year and final settlements with CMS in the second and third quarter.

Cash Flow from Investing Activities

During the 2025, 2024 and 2023 periods, we acquired various businesses for approximately $81 million, $89 million and $233 million, respectively, net of cash and cash equivalents received. Net proceeds from the sale of business were $115 million in the 2025 period.

Our ongoing capital expenditures primarily relate to our information technology initiatives, support of services in our primary care operations including medical and administrative facility improvements necessary for activities such as the provision of care to members, claims processing, billing and collections, wellness solutions, care coordination, regulatory compliance and customer service. Total net capital expenditures, excluding acquisitions, were $523 million, $568 million and $794 million in the 2025, 2024 and 2023 periods, respectively.

Net proceeds of investment securities were $2.8 billion in the 2025 period. Net purchases of investment securities were $2.2 billion and $2.5 billion in the 2024 and 2023 periods, respectively.

Cash Flow from Financing Activities

Our financing cash flows are significantly impacted by the timing of claims payments and the related receipts from CMS associated with Medicare Part D claim subsidies for which we do not assume risk. Monthly prospective payments from CMS for reinsurance and low-income cost subsidies are based on assumptions submitted with our annual bid. Settlement of the reinsurance and low-income cost subsidies is based on a reconciliation made approximately 9 months after the close of each calendar year. Claim payments were higher than receipts from CMS associated with Medicare Part D claim subsidies for which we do not assume risk by $1 billion and $1.8 billion in the 2025 and 2024 periods, respectively, and receipts from CMS associated with Medicare Part D claim subsidies for which we do not assume risk were higher than claim payments by $0.8 billion in the 2023 period. Our net receivable from CMS for subsidies and brand name prescription drug discounts was $1.5 billion at December 31, 2025 compared to a net receivable of $530 million at December 31, 2024.

Under our administrative services only TRICARE contract, health care costs payments for which we do not assume risk exceeded reimbursements from the federal government by $74 million and $92 million in the 2025 and 2024 periods, respectively, and reimbursements from the federal government exceeded health care costs payments for which we do not assume risk by $57 million in the 2023 period.

In March 2025, we issued $750 million of 5.550% unsecured senior notes due May 1, 2035, $500 million of 6.000% unsecured senior notes due May 1, 2055, and an additional $250 million of our existing 5.375% unsecured senior notes due April 15, 2031. Our net proceeds, reduced for the underwriters' discounts and commissions paid, were $1.481 billion. We used the net proceeds of these offerings to repay the remaining $577 million aggregate principal amount of our 4.500% unsecured senior notes on their maturity date of April 1, 2025. The remaining net proceeds will be used for general corporate purposes, which may include the repayment of our existing indebtedness, including borrowings under our commercial paper program.

In November 2024, we repaid our $500 million 5.700% unsecured senior notes due March 13, 2026.

In March 2024, we issued $1.5 billion of 5.375% unsecured senior notes due April 15, 2031 and $1.0 billion of 5.750% unsecured senior notes due April 15, 2054. Our net proceeds, reduced for the underwriters' discounts and commissions paid, were $2.2 billion. We used the net proceeds for general corporate purposes, which included the repayment of existing indebtedness, including borrowings under our commercial paper program.

In November 2023, we issued $500 million of 5.750% unsecured senior notes due December 1, 2028 and $850 million of 5.950% unsecured senior notes due March 15, 2034. Our net proceeds, reduced for the underwriters' discounts and commissions paid, were $1.3 billion.

In March 2023, we issued $500 million of 5.700% unsecured senior notes due March 13, 2026 and $750 million of 5.500% unsecured senior notes due March 15, 2053. Our net proceeds, reduced for the underwriters' discounts and commissions paid, were $1.2 billion. We used the net proceeds to repay outstanding amounts under our $500 million Delayed Draw Term Loan. The remaining net proceeds were used for general corporate purposes, which included the repayment of existing indebtedness, including borrowings under our commercial paper program.

In May 2025, we entered into a Rule 10b5-1 Repurchase Plan to repurchase a portion of our $750 million aggregate principal amount of 1.350% senior notes maturing in February 2027 and a portion of our $600 million aggregate principal amount of 3.950% senior notes maturing in March 2027 during the period beginning on May 1, 2025 and ending on August 29, 2025. For the year ended December 31, 2025, we repurchased $200 million principal amount of these senior notes for approximately $194 million cash.

In October 2025, we entered into a Rule 10b5-1 Repurchase Plan to repurchase a portion of our $750 million aggregate principal amount of 2.150% senior notes maturing in February 2032, a portion of our $500 million aggregate principal amount of 3.125% senior notes maturing in August 2029 and a portion of our $750 million aggregate principal amount of 3.700% senior notes maturing in March 2029 during the period beginning on October 3, 2025 and ending on December 31, 2025. For the period ended December 31, 2025, we repurchased $200 million principal amount of these senior notes for approximately $177 million cash.

In August 2023, we entered into a Rule 10b5-1 Repurchase Plan to repurchase a portion of our $750 million aggregate principal amount of 1.350% senior notes maturing in February 2027, our $600 million aggregate principal amount of 3.950% senior notes maturing in March 2027, our $750 million aggregate principal amount of 3.700% senior notes maturing in March 2029, and our $500 million aggregate principal amount of 3.125% senior notes maturing in August 2029 during the period beginning on August 7, 2023 and ending on November 15, 2023. For the year ended December 31, 2023, we repurchased $339 million principal amount of these senior notes for approximately $310 million cash.

In March 2023, we entered into a Rule 10b5-1 Repurchase Plan to repurchase a portion of our $1.5 billion aggregate principal amount of 0.650% senior notes maturing in August 2023 and our $600 million aggregate principal amount of 3.850% senior notes maturing in October 2024 during the period beginning on March 13, 2023 and ending on July 21, 2023. For the year ended December 31, 2023, we repurchased $361 million principal amount of these senior notes for approximately $358 million cash. We repaid the remaining $1.2 billion aggregate principal amount of our 0.650% senior notes due on their maturity date of August 3, 2023. We repaid the remaining $559 million aggregate principal amount of our 3.850% senior notes on their maturity date of October 1, 2024.

We participate in a securities lending program where we loan certain investment securities for short periods of time in exchange for collateral. Net proceeds from the securities lending program were $220 million and $418 million in 2025 and 2024, respectively. We have previously entered into an uncommitted receivables purchase facility under which certain pharmaceutical rebate receivables may be sold on a non-recourse basis to a financial institution. Net repayments from the uncommitted receivables purchase facility were $123 million in 2025. Net proceeds provided by the uncommitted receivables purchase facility were $123 million in 2024.

We participate in a commercial paper program. Net repayments from issuance of commercial paper were $5 million in 2025 and the maximum principal amount outstanding at any one time during 2025 was $1.2 billion. Net repayments from the issuance of commercial paper were $907 million in 2024 and the maximum principal amount outstanding at any one time during 2024 was $2.7 billion. Net proceeds from issuance of commercial paper were $211 million in 2023 and the maximum principal amount outstanding at any one time during 2023 was $3.3 billion.

We received a short-term cash advance of $100 million from FHLB with certain of our marketable securities as collateral and subsequently repaid the outstanding balance in December 2023.

We repurchased common shares for $151 million, $817 million and $1.6 billion in 2025, 2024 and 2023, respectively, under share repurchase plans authorized by the Board of Directors and in connection with employee stock plans.

We paid dividends to stockholders of $430 million in 2025, $431 million in 2024, and $431 million in 2023.

Acquisitions & Divestitures

For a detailed discussion regarding acquisitions and divestitures, refer to Note 3 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

Liquidity Requirements

We believe our cash balances, investment securities, operating cash flows, and funds available under our credit agreement and our commercial paper program or from other public or private financing sources, taken together, provide adequate resources to fund ongoing operating and regulatory requirements, acquisitions, future expansion opportunities, and capital expenditures for at least the next twelve months, as well as to refinance or repay debt, and repurchase shares.

Adverse changes in our credit rating may increase the rate of interest we pay and may impact the amount of credit available to us in the future. Our investment-grade credit rating at December 31, 2025 was BBB according to Standard & Poor’s Rating Services, or S&P, and Baa2 according to Moody’s Investors Services, Inc., or Moody’s. A downgrade by S&P to BB+ or by Moody’s to Ba1 triggers an interest rate increase of 25 basis points with respect to $250 million of our senior notes. Successive one notch downgrades increase the interest rate an additional 25 basis points, or annual interest expense by approximately $1 million, up to a maximum 100 basis points, or annual interest expense by approximately $3 million.

In addition, we operate as a holding company in a highly regulated industry. Humana Inc., our parent company, is dependent upon dividends and administrative expense reimbursements from our subsidiaries, most of which are subject to regulatory restrictions. We continue to maintain significant levels of aggregate excess statutory capital and surplus in our state-regulated operating subsidiaries. Cash, cash equivalents, and short-term investments at the parent company were $1.5 billion at December 31, 2025 compared to $0.6 billion at December 31, 2024. This increase primarily reflects working capital changes, net proceeds from the issuance of senior notes, and proceeds from sale of business,partially offset by repayments of senior notes, capital contributions to certain subsidiaries, cash dividends to shareholders, capital expenditures, and common stock repurchases. Our use of operating cash derived from our non-insurance subsidiaries, such as our CenterWell segment, is generally not restricted by departments of insurance (or comparable state regulators). Our regulated insurance subsidiaries paid dividends to our parent company of $1.1 billion in 2025, $1.5 billion in 2024, and $1.8 billion in 2023. Subsidiary capital requirements from significant premium growth may impact the amount of regulated subsidiary dividends. Refer to our parent company financial statements and accompanying notes in Schedule I - Parent Company Financial Information. The amount of ordinary dividends that may be paid to our parent company in 2026 is approximately $1.1 billion, in the aggregate. Actual dividends paid may vary due to consideration of excess statutory capital and surplus and expected future surplus requirements related to, for example, premium volume and product mix.

On February 13, 2026, we completed the acquisition of a primary care business for consideration of approximately $941 million.

Regulatory Requirements

Off-Balance Sheet Arrangements

As of December 31, 2025, we were not involved in any special purpose entity, or SPE, transactions. For a detailed discussion of off-balance sheet arrangements, please refer to Note 17 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations is based upon our consolidated financial statements and accompanying notes, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these financial statements and accompanying notes requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We continuously evaluate our estimates and those critical accounting policies primarily related to benefits expense and revenue recognition as well as accounting for impairments related to our investment securities, goodwill, indefinite-lived and long-lived assets. These estimates are based on knowledge of current events and anticipated future events and, accordingly, actual results ultimately may differ from those estimates. We believe the following critical accounting policies involve the most significant judgments and estimates used in the preparation of our consolidated financial statements.

Benefits Expense Recognition

Benefits expense is recognized in the period in which services are provided and includes an estimate of the cost of services which have been incurred but not yet reported, or IBNR. Our reserving practice is to consistently recognize the actuarial best point estimate within a level of confidence required by actuarial standards. For further discussion of our reserving methodology, including our use of completion and claims per member per month trend factors to estimate IBNR, refer to Note 2 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

The completion and claims per member per month trend factors are the most significant factors impacting the IBNR estimate. The portion of IBNR estimated using completion factors for claims incurred prior to the most recent two months is generally less variable than the portion of IBNR estimated using trend factors. The following table illustrates the sensitivity of these factors, experience and the estimated potential impact on our operating results caused by reasonably likely changes in these factors based on December 31, 2025 data:

Completion Factor (a): Claims Trend Factor (b):

(dollars in millions)

(a)Reflects estimated potential changes in benefits payable at December 31, 2025 caused by changes in completion factors for incurred months prior to the most recent two months.

(b)Reflects estimated potential changes in benefits payable at December 31, 2025 caused by changes in annualized claims trend used for the estimation of per member per month incurred claims for the most recent two months.

(c)The factor change indicated represents the percentage point change.

The following table provides a historical perspective regarding the accrual and payment of our benefits payable. Components of the total incurred claims for each year include amounts accrued for current year estimated benefits expense as well as adjustments to prior year estimated accruals. Refer to Note 11 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K for information about incurred and paid claims development as of December 31, 2025 as well as cumulative claim frequency and the total of IBNR included within the net incurred claims amounts.

The following table summarizes the changes in estimate for incurred claims related to prior years attributable to our key assumptions. As previously described, our key assumptions consist of trend and completion factors. The amounts below represent the difference between our original estimates and the actual benefits expense ultimately incurred as determined from subsequent claim payments.

Favorable Development by Changes in Key Assumptions

(dollars in millions)

(a)The factor change indicated represents the percentage point change.

As previously discussed, our reserving practice is to consistently recognize the actuarial best estimate of our ultimate liability for claims, which generally results in favorable reserve development, or reserves that are considered redundant. We experienced favorable medical claims reserve development related to prior fiscal years of $1.0 billion in 2025, $701 million in 2024, and $872 million in 2023.

The favorable medical claims reserve development for 2025, 2024, and 2023 primarily reflects the consistent application of trend and completion factors.

Our favorable development for each of the years presented above is discussed further in Note 11 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K.

We continually adjust our historical trend and completion factor experience with our knowledge of recent events that may impact current trends and completion factors when establishing our reserves. Because our reserving practice is to consistently recognize the actuarial best point estimate as required by actuarial standards, there is a reasonable possibility that variances between actual trend and completion factors and those assumed in our December 31, 2025 estimates would fall within the ranges previously presented in our sensitivity table.

Revenue Recognition

Our Medicare contracts with CMS renew annually. We generally establish one-year specialty membership contracts, subject to cancellation on a 30-day written notice. Our military services contracts with the federal government and certain contracts with various state Medicaid programs generally are multi-year contracts subject to annual renewal provisions.

We receive monthly premiums from the federal government and various states according to government specified payment rates and various contractual terms. We bill and collect member premiums on a monthly basis. Changes in Medicare premium revenues resulting from the periodic changes in risk-adjustment scores derived from medical diagnoses for our membership are estimated by projecting the ultimate annual premium and recognized ratably during the year with adjustments each period to reflect changes in the ultimate premium.

Premiums revenue is estimated by multiplying the membership covered under the various contracts by the contractual rates. Premiums revenue is recognized as income in the period members are entitled to receive services, and is net of estimated uncollectible amounts, retroactive membership adjustments, and adjustments to recognize rebates under the minimum benefit ratios required under the Patient Protection and Affordable Care Act and The Health Care and Education Reconciliation Act of 2010, which we collectively refer to as the Health Care Reform Law. Medicare Advantage and Medicaid products are subject to minimum benefit ratio requirements. Estimated calendar year rebates recognized ratably during the year are revised each period to reflect current experience. Retroactive membership adjustments result from enrollment changes not yet processed, or not yet reported by the federal government and various states. We routinely monitor the collectability of specific accounts, the aging of receivables, historical retroactivity trends, estimated rebates, as well as prevailing and anticipated economic conditions, and reflect any required adjustments in current operations. Premiums received prior to the service period are recorded as unearned revenues.

Medicare Risk-Adjustment Provisions

CMS uses a risk-adjustment model that adjusts premiums paid to Medicare Advantage, or MA, plans according to health status of covered members. The risk-adjustment model, which CMS implemented pursuant to the Balanced Budget Act of 1997 (BBA) and the Benefits Improvement and Protection Act of 2000 (BIPA), generally pays more where a plan's membership has higher expected costs. Under this model, rates paid to MA plans are based on actuarially determined bids, which include a process whereby our prospective payments are based on our estimated cost of providing standard Medicare-covered benefits to an enrollee with a "national average risk profile." That baseline payment amount is adjusted to account for certain demographic characteristics and health status of our enrolled members. Under the risk-adjustment methodology, all MA plans must collect from providers and submit the necessary diagnosis code information to CMS within prescribed deadlines. The CMS risk-adjustment model uses the diagnosis data, collected from providers, to calculate the health status-related risk-adjusted premium payment to MA plans, which CMS further adjusts for coding pattern differences between the health plans and the government fee-for-service (FFS) program. We generally rely on providers, including certain providers in our network who are our employees, to code their claim submissions with appropriate diagnoses, which we send to CMS as the basis for our health status-adjusted payment received from CMS under the actuarial risk-adjustment model. We also rely on these providers to document appropriately all medical data, including the diagnosis data submitted with claims. In addition, we conduct medical record reviews as part of our data and payment accuracy compliance efforts, to more accurately reflect diagnosis conditions under the risk adjustment model. For additional information, refer to Note 17 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" and Part I, Item 1A, "Risk Factors" of this Form 10-K.

Investment Securities

Investment securities totaled $16.2 billion, or 33% of total assets at December 31, 2025, and $18.6 billion, or 40% of total assets at December 31, 2024. The investment portfolio was primarily comprised of debt securities, detailed below, at December 31, 2025 and December 31, 2024. The fair value of investment securities were as follows at December 31, 2025 and 2024:

(dollars in millions)

U.S. Treasury and other U.S. government corporations and agencies:

Tax-exempt municipal securities 428 2.6 % 526 2.8 %

Mortgage-backed securities:

Approximately 97% of our debt securities were investment-grade quality, with a weighted average credit rating of AA- by S&P at December 31, 2025. Most of the debt securities that were below investment-grade were rated B. Tax-exempt municipal securities were diversified among general obligation bonds of states and local municipalities in the United States as well as special revenue bonds issued by municipalities to finance specific public works projects such as utilities, water and sewer, transportation, or education. Our general obligation bonds are diversified across the United States with no individual state exceeding approximately 1% of our total debt securities. Our investment policy limits investments in a single issuer and requires diversification among various asset types.

Gross unrealized losses and fair values aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position were as follows at December 31, 2025:

Mortgage-backed securities:

Under the current expected credit losses model, or CECL, credit losses on available for sale debt securities are recognized through an allowance for credit losses rather than as reductions in the amortized cost of the securities. For debt securities whose fair value is less than their amortized cost which we do not intend to sell or are not required to sell, we evaluate the expected cash flows to be received as compared to amortized cost and determine if an expected credit loss has occurred. In the event of an expected credit loss, only the amount of the impairment associated with the expected credit loss is recognized in income with the remainder, if any, of the loss recognized in other comprehensive income. To the extent we have the intent to sell the debt security or it is more likely than not we will be required to sell the debt security before recovery of our amortized cost basis, we recognize an impairment loss in income in an amount equal to the full difference between the amortized cost basis and the fair value.

Potential expected credit loss impairment is considered using a variety of factors, including the extent to which the fair value has been less than cost; adverse conditions specifically related to the industry, geographic area or financial condition of the issuer or underlying collateral of a debt security; changes in the quality of the debt security's credit enhancement; payment structure of the debt security; changes in credit rating of the debt security by the rating agencies; failure of the issuer to make scheduled principal or interest payments on the debt security and changes in prepayment speeds. For debt securities, we take into account expectations of relevant market and economic data. For example, with respect to mortgage and asset-backed securities, such data includes underlying loan level data and structural features such as seniority and other forms of credit enhancements. We estimate the amount of the expected credit loss component of a debt security as the difference between the amortized cost and the present value of the expected cash flows of the security. The present value is determined using the best estimate of future cash flows discounted at the implicit interest rate at the date of purchase. The expected credit loss cannot exceed the full difference between the amortized cost basis and the fair value.

obligation to return the collateral within trade accounts payable and accrued expenses on our consolidated balance sheet at the end of the reporting period. Collateral received in the form of securities is not recorded in our consolidated balance sheets because, absent default by the borrower, we do not have the right to sell, pledge or otherwise reinvest securities collateral. Loaned securities continue to be carried as investment securities on the consolidated balance sheet at the end of the reporting period. Earnings on the invested cash collateral, net of expense, associated with the securities lending payable are recorded as investment income.

The risks inherent in assessing the impairment of an investment include the risk that market factors may differ from our expectations, facts and circumstances factored into our assessment may change with the passage of time, or we may decide to subsequently sell the investment. The determination of whether a decline in the value of an investment is related to a credit event requires us to exercise significant diligence and judgment. The discovery of new information and the passage of time can significantly change these judgments. The status of the general economic environment and significant changes in the national securities markets influence the determination of fair value and the assessment of investment impairment. There is a continuing risk that declines in fair value may occur and additional material realized losses from sales or expected credit loss impairments may be recorded in future periods.

All issuers of debt securities we own that were trading at an unrealized loss at December 31, 2025 remain current on all contractual payments. After taking into account these and other factors previously described, we believe these unrealized losses primarily were caused by an increase in market interest rates in the current markets since the time these debt securities were purchased. At December 31, 2025, we did not intend to sell any debt securities with an unrealized loss position in accumulated other comprehensive income, and it is not likely that we will be required to sell these debt securities before recovery of their amortized cost basis. Additionally, we did not record any material credit allowances for debt securities that were in an unrealized loss position at December 31, 2025, 2024 or 2023.

Goodwill, Indefinite-lived and Long-lived Assets

At December 31, 2025, goodwill, indefinite-lived and other long-lived assets represented 27% of total assets and 74% of total stockholders’ equity, compared to 29% and 83%, respectively, at December 31, 2024. The decrease in goodwill, indefinite-lived and other long-lived assets as a percentage of total assets is primarily attributable to the increase in cash and cash equivalents and other assets, partially offset by the decrease in investment securities. The decrease in goodwill, indefinite-lived and other long-lived assets as a percentage of total stockholders' equity is primarily attributable to the increase in retained earnings and the decrease in accumulated other comprehensive loss.

For goodwill, we are required to test at least annually for impairment at a level of reporting referred to as the reporting unit, and more frequently if adverse events or changes in circumstances indicate that the asset may be impaired. A reporting unit either is our operating segments or one level below the operating segments, referred to as a component, which comprise our reportable segments. A component is considered a reporting unit if the component constitutes a business for which discrete financial information is available that is regularly reviewed by management. We are required to aggregate the components of an operating segment into one reporting unit if they have similar economic characteristics. Goodwill is assigned to the reporting unit that is expected to benefit from a specific acquisition.

We perform a quantitative assessment to review goodwill for impairment to determine both the existence and amount of goodwill impairment, if any. Our strategy, long-range business plan, and annual planning process support our goodwill impairment tests. These tests are performed, at a minimum, annually in the fourth quarter, and are based on an evaluation of future discounted cash flows. We rely on this discounted cash flow analysis to determine fair value. However, outcomes from the discounted cash flow analysis are compared to other market approach valuation methodologies for reasonableness. We use discount rates that correspond to a market-based weighted-average cost of capital and terminal growth rates that correspond to long-term growth prospects, consistent with the long-term inflation rate. Key assumptions in our cash flow projections, including changes in membership, premium yields, medical and operating cost trends, and certain government contract extensions, are consistent with those utilized in our long-range business plan and annual planning process. If these assumptions differ from actual, including the impact of the Health Care Reform Law or changes in government reimbursement rates, the estimates

underlying our goodwill impairment tests could be adversely affected. The fair value of our reporting units with significant goodwill exceeded carrying amounts by a substantial margin. However, unfavorable changes in key assumptions or combinations of assumptions including a significant increase in the discount rate, decrease in the long-term growth rate or substantial reduction in our underlying cash flow assumptions, including revenue expectations and growth rates, operating cost trends, and projected operating income could have a significant negative impact on the estimated fair value of our home solutions reporting unit, which accounted for $4.4 billion of goodwill. Impairment tests completed for 2025, 2024, and 2023 did not result in an impairment loss.

Indefinite-lived intangible assets relate to Certificate of Needs (CON) and Medicare licenses acquired in connection with our CenterWell Home Health (formerly Kindred at Home) acquisition with a carrying value of $1.1 billion at December 31, 2025. Like goodwill, we are required to test at least annually for impairment and more frequently if adverse events or changes in circumstances indicate that the asset may be impaired. These tests are performed, at a minimum, annually in the fourth quarter. If the carrying amount of an indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized. Fair values of indefinite-lived intangible assets are determined based on the income approach. For our CON intangible assets, unfavorable changes in key assumptions or combinations of assumptions, including a significant increase in the discount rate, decrease in the long-term growth rate or substantial reduction in the underlying cash flow assumptions, including revenue growth rates, operating cost trends, and projected operating income could have a significant negative impact on the estimated fair value of our CON intangible assets, which account for $790 million of our intangible assets. Impairment tests completed on our indefinite-lived intangible assets for 2025, 2024 and 2023 resulted in impairment charges of $128 million, $200 million and $55 million, respectively. These charges reflect the amount by which the carrying value exceeded its estimated fair value. The fair values of the assets were measured using Level 3 inputs, such as projected revenues and operating cash flows.

Long-lived assets consist of property and equipment and other definite-lived intangible assets. These assets are depreciated or amortized over their estimated useful life, and are subject to impairment reviews. We periodically review long-lived assets whenever adverse events or changes in circumstances indicate the carrying value of the asset may not be recoverable. In assessing recoverability, we must make assumptions regarding estimated future cash flows and other factors to determine if an impairment loss may exist, and, if so, estimate fair value. We also must estimate and make assumptions regarding the useful life we assign to our long-lived assets. If these estimates or their related assumptions change in the future, we may be required to record impairment losses or change the useful life, including accelerating depreciation or amortization for these assets. Other than the impairment charges as described in Footnote 2 to the audited Consolidated Financial Statements included in Part II, Item 8, "Financial Statements and Supplementary Data" of this Form 10-K, there were no other impairment losses in the last three years.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Our earnings and financial position are exposed to financial market risk, including those resulting from changes in interest rates.

The level of our pretax earnings is subject to market risk due to changes in interest rates and the resulting impact on investment income and interest expense. We have entered into interest-rate swap agreements with major financial institutions to convert our interest-rate exposure on some of our senior notes payable from fixed rates to variable rates, based on Secured Overnight Financing Rate (SOFR), to align interest costs more closely with floating interest rates received on our cash equivalents and investment securities Under the revolving credit agreements, at our option, we can borrow on either a competitive advance basis or a revolving credit basis. The revolving credit portion bears interest at either Term SOFR or the base rate plus a spread. The competitive advance portion of any borrowings will bear interest at market rates prevailing at the time of borrowing on either a fixed rate or a floating rate based on Term SOFR, at our option. There were no borrowings outstanding under our credit agreements at December 31, 2025 or December 31, 2024.

Interest rate risk also represents a market risk factor affecting our consolidated financial position due to our significant investment portfolio, consisting primarily of fixed maturity securities of investment-grade quality with a weighted average S&P credit rating of AA- at December 31, 2025. Our net unrealized loss position decreased $562

million from a net unrealized loss position of $1.4 billion at December 31, 2024 to a net unrealized loss position of $0.8 billion at December 31, 2025. At December 31, 2025, we had gross unrealized losses of $0.9 billion on our investment portfolio primarily due to an increase in market interest rates since the time the securities were purchased. We did not record any material credit allowances for debt securities that were in an unrealized loss position during 2025 and 2024. While we believe that these impairments will be recovered and we currently do not have the intent to sell such securities, given the current market conditions and the significant judgments involved, there is a continuing risk that future declines in fair value may occur and material realized losses from sales or credit loss impairments may be recorded in future periods.

Duration is the time-weighted average of the present value of the bond portfolio’s cash flow. Duration is indicative of the relationship between changes in fair value and changes in interest rates, providing a general indication of the sensitivity of the fair values of our fixed maturity securities to changes in interest rates. However, actual fair values may differ significantly from estimates based on duration. The average duration of our investment portfolio, including cash and cash equivalents, was approximately 3.6 years as of December 31, 2025 and 3.8 years as of December 31, 2024. Based on the duration including cash equivalents, a 1% increase in interest rates would generally decrease the December 31, 2025 fair value of our securities by approximately $723 million.

We have also evaluated the impact on our investment income and interest expense resulting from a hypothetical change in interest rates of 100, 200, and 300 basis points over the next twelve-month period, as reflected in the following table. The evaluation was based on our investment portfolio, outstanding indebtedness, and outstanding swap contract portfolio at December 31, 2025 and 2024. Our investment portfolio consists of cash, cash equivalents, and investment securities. The modeling technique used to calculate the pro forma net change in pretax earnings considered the cash flows related to fixed income investments and debt, which are subject to interest rate changes during a prospective twelve-month period. This evaluation measures parallel shifts in interest rates and may not account for certain unpredictable events that may affect interest income, including unexpected changes of cash flows into and out of the portfolio, changes in the asset allocation, including shifts between taxable and tax-exempt securities, spread changes specific to various investment categories and the mix of short-term versus long-term debt. In the past ten years, changes in 10 year US treasury rates during the year have not exceeded 300 basis points, have changed between 200 and 300 basis points one time, have changed between 100 and 200 basis points five times, and have changed by less than 100 basis points four times.

(in millions)

(a)As of December 31, 2025 and 2024, none of our investments had interest rates below 1%.

(b)The interest rate under our senior notes, which represents 100% at December 31, 2025 and 2024, respectively, of total debt, is fixed, unaffected by changes in interest rates.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. REPORTING ENTITY

Nature of Operations

Humana Inc., headquartered in Louisville, Kentucky, is committed to putting health first – for our teammates, our customers, and our company. Through our Humana insurance services, and our CenterWell health care services, we make it easier for the millions of people we serve to achieve their best health – delivering the care and service they need, when they need it. These efforts are leading to a better quality of life for Medicare and Medicaid participants, families, individuals, military service personnel, and communities at large. References throughout these notes to consolidated financial statements to “we,” “us,” “our,” “Company,” and “Humana,” mean Humana Inc. and its subsidiaries. We derived approximately 83% of our total premiums and services revenue from contracts with the federal government in 2025, including 14% related to our federal government contracts with the Centers for Medicare and Medicaid Services, or CMS, to provide health insurance coverage for individual Medicare Advantage members in Florida. CMS is the federal government’s agency responsible for administering the Medicare program.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

Our financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America. Our consolidated financial statements include the accounts of Humana Inc. and subsidiaries that the Company controls, including variable interest entities associated with medical practices for which we are the primary beneficiary. We do not own many of our medical practices but instead enter into exclusive management agreements with the affiliated Professional Associations, or P.A.s, that operate these medical practices. Based upon the provisions of these agreements, these affiliated P.A.s are variable interest entities and we are the primary beneficiary, and accordingly we consolidate the affiliated P.A.s. All significant intercompany balances and transactions have been eliminated.

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires us to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The areas involving the most significant use of estimates are the estimation of benefits payable, the impact of risk adjustment provisions related to our Medicare contracts, the valuation and related impairment recognition of investmentsecurities, and the valuation and related impairment recognition of long-lived assets, including goodwill and indefinite-lived intangible assets. These estimates are based on knowledge of current events and anticipated future events, and accordingly, actual results may ultimately differ materially from those estimates.

Cash and Cash Equivalents

Cash and cash equivalents include cash, time deposits, money market funds, commercial paper, other money market instruments, and certain U.S. Government securities with an original maturity of three months or less. Carrying value approximates fair value due to the short-term maturity of the investments.

Investment Securities

Investment securities, which consist of debt securities, are stated at fair value. Our debt securities have been categorized as available for sale. Debt securities available for current operations, as well as our equity securities, are classified as current assets, and debt securities available to fund our professional and other self-insurance liability requirements, as well as restricted statutory deposits, are classified as long-term assets. For the purpose of determining realized gross gains and losses for debt securities sold, that are included as a component of investment income in the consolidated statements of income, the cost of investment securities sold is based upon specific identification. Unrealized holding gains and losses for debt securities, net of applicable deferred taxes, are included in other comprehensive income or loss as a component of stockholders’ equity until realized from a sale or an expected credit loss is recognized. For the purpose of determining gross gains and losses for equity securities, changes in fair value at the reporting date are included as a component of investment income in the consolidated statements of income.

Humana Inc.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

economic data. For example, with respect to mortgage and asset-backed securities, such data includes underlying loan level data and structural features such as seniority and other forms of credit enhancements. We estimate the amount of the expected credit loss component of a debt security as the difference between the amortized cost and the present value of the expected cash flows of the security. The present value is determined using the best estimate of future cash flows discounted at the implicit interest rate at the date of purchase. The expected credit loss cannot exceed the full difference between the amortized cost basis and the fair value.

We participate in a securities lending program to optimize investment income. We loan certain investment securities for short periods of time in exchange for collateral initially equal to at least 102% of the fair value of the investment securities on loan. The fair value of the loaned investment securities is monitored on a daily basis, with additional collateral obtained or refunded as the fair value of the loaned investment securities fluctuates. The collateral, which may be in the form of cash or U.S. Government securities, is deposited by the borrower with an independent lending agent. Any cash collateral, which is reinvested by the lending agent primarily in short-term, highly liquid investments, is recorded as a securities lending collateral asset within other current assets on our consolidated balance sheet at the end of the reporting period. We record a corresponding liability to reflect our obligation to return the collateral within trade accounts payable and accrued expenses on our consolidated balance sheet at the end of the reporting period. Collateral received in the form of securities is not recorded in our consolidated balance sheets because, absent default by the borrower, we do not have the right to sell, pledge or otherwise reinvest securities collateral. Loaned securities continue to be carried as investment securities on the consolidated balance sheet at the end of the reporting period. Earnings on the invested cash collateral, net of expense, associated with the securities lending payable are recorded as investment income.

Receivables and Revenue Recognition

Premiums Revenue

Humana Inc.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Medicare Part D

We cover prescription drug benefits in accordance with Medicare Part D under multiple contracts with CMS. The payments we receive monthly from CMS and members, which are determined from our annual bid, represent amounts for providing prescription drug insurance coverage. We recognize premiums revenue for providing this insurance coverage ratably over the term of our annual contract. Our CMS payment is subject to risk sharing through the Medicare Part D risk corridor provisions. Receipts for reinsurance, low-income cost subsidies, and manufacturer discounts on certain prescription drugs represent payments for prescription drug costs for which we are not at risk.

The risk corridor provisions compare costs targeted in our bids to actual prescription drug costs, limited to actual costs that would have been incurred under the standard coverage as defined by CMS. Variances exceeding certain thresholds may result in CMS making additional payments to us or require us to refund to CMS a portion of the premiums we received. As risk corridor provisions are considered in our overall annual bid process, we estimate and recognize an adjustment to premiums revenue related to these provisions based upon pharmacy claims experience. We record a receivable or payable at the contract level and classify the amount as current or long-term in our consolidated balance sheets based on the timing of expected settlement.

Reinsurance and low-income cost subsidies represent funding from CMS in connection with the Medicare Part D program for which we assume no risk. Reinsurance subsidies represent funding from CMS for its portion of prescription drug costs which exceed the member’s out-of-pocket threshold, or the catastrophic coverage level. Low-income cost subsidies represent funding from CMS for all or a portion of the deductible, the coinsurance and co-payment amounts above the out-of-pocket threshold for low-income beneficiaries. Monthly prospective payments from CMS for reinsurance and low-income cost subsidies are based on assumptions submitted with our annual bid. A reconciliation and related settlement of CMS’s prospective subsidies against actual prescription drug costs we paid is made after the end of the year. The Health Care Reform Law mandated consumer discounts of 75% on brand name and generic prescription drugs for Part D plan participants in the coverage gap prior to January 1, 2025. These discounts were funded by CMS and pharmaceutical manufacturers while we administered the application of these funds. Effective January 1, 2025, the Medicare Part D coverage gap was eliminated as mandated by the Inflation Reduction Act of 2022. The standard Part D benefit now comprises three phases: the deductible phase, the initial coverage phase and the catastrophic coverage phase. Beneficiaries' out-of-pocket expenses for covered prescription drugs are capped at $2,000, after which they incur no additional cost sharing for the remainder of the year. In addition, the Coverage Gap Discount Program was replaced by the Manufacturer Discount Program, requiring pharmaceutical manufacturers to provide discounts on brand name drugs during both the initial coverage and catastrophic phases.

We account for the funding of subsidies and discounts for which we assume no risk as a deposit in our consolidated balance sheets and as a financing activity under receipts (payments) from contract deposits, net in our consolidated statements of cash flows.

(in millions)

We do not recognize premiums revenue or benefit expenses for these subsidies or discounts. Receipt and payment activity is accumulated at the contract level and recorded in our consolidated balance sheets in other current assets or trade accounts payable and accrued expenses depending on the contract balance at the end of the reporting period.

Settlement of the reinsurance and low-income cost subsidies as well as the risk corridor payment is based on a reconciliation made approximately 9 months after the close of each calendar year. Settlement with CMS for brand name prescription drug discounts is based on a reconciliation made approximately 14 to 18 months after the close of

Humana Inc.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

each calendar year. We continue to revise our estimates with respect to the risk corridor provisions based on subsequent period pharmacy claims data. For additional information regarding amounts recorded to our consolidated balance sheets related to the risk corridor settlement and subsidies from CMS with respect to the Medicare Part D program, refer to Note 7.

Patient services revenue

Patient services include services related to pharmacy solutions, primary care, and home solutions and other services and capabilities to promote wellness and advance population health.

For our pharmacy solutions business, external pharmacy revenues include the cost of pharmaceuticals (net of rebates), a negotiated dispensing fee and customer co-payments for drugs dispensed through our CenterWell Pharmacy (our mail-order pharmacy business), CenterWell Specialty Pharmacy, and retail pharmacies jointly located within CenterWell Senior primary care clinics. Pharmacy products are billed to customers based on the number of transactions occurring during the billing period. Services revenues related to product revenues from dispensing prescriptions are recorded when the prescription or product is shipped.

Our primary care business recognizes revenues for certain value-based arrangements. Under these value-based arrangements, we enter into agreements with health plans to stand ready to deliver, integrate, direct and control the administration and management of certain health care services for our patients. In exchange, we receive a premium that is typically paid on a per member per month basis. These value-based arrangements represent a single performance obligation where revenues are recognized in the period in which we are obligated to provide integrated health care services to our patients. Fee-for-service revenue is recognized at agreed upon rates, net of contractual allowances, as the performance obligation is completed on the date of service.

For our home solutions business, revenues include net patient services revenue recorded based upon established billing rates, net of contractual allowances, discounts, or other implicit price concessions, and are recognized as performance obligations are satisfied, which is in the period services are rendered.

For the year ended December 31, 2025, revenue recognized from performance obligations related to prior periods (for example, due to changes in transaction price), was not material. Further, revenue expected to be recognized in any future year related to remaining performance obligations is not material.

Other services revenue

Services revenue includes the processing of claims, offering access to our provider networks and clinical programs, and responding to customer service inquiries from members of self-funded groups. Services revenue is recognized in the period services are performed and are net of estimated uncollectible amounts. We routinely monitor the collectability of specific accounts, the aging of receivables, as well as prevailing and anticipated economic conditions, and reflect any required adjustments in current operations. Services revenue received prior to the service period is recorded as unearned revenue.

Under our TRICARE contracts with the Department of Defense (DoD) we provide administrative services, including offering access to our provider networks and clinical programs, claim processing, customer service, enrollment, and other services, while the federal government retains all of the risk of the cost of health benefits. We account for revenues under our contracts net of estimated health care costs similar to an administrative services fee only agreement. Our contracts include fixed administrative services fees and incentive fees and penalties. Administrative services fees are recognized as services are performed.

Our TRICARE members are served by both in-network and out-of-network providers in accordance with our contracts. We pay health care costs related to these services to the providers and are subsequently reimbursed by the DoD for such payments.We account for the payments of the federal government’s claims and the related reimbursements under deposit accounting in our consolidated balance sheets and as a financing activity under receipts (payments) from contract deposits, net in our consolidated statements of cash flows.

Receivables

Receivables, including premium receivables, patient services revenue receivables, and other services revenue receivables, are shown net of allowances for estimated uncollectible accounts, retroactive membership adjustments, and contractual allowances.

At December 31, 2025 and 2024, accounts receivable related to services were $367 million and $360 million, respectively. For the years ended December 31, 2025, 2024 and 2023, we had no material bad-debt expense and there were no material contract assets, contract liabilities or deferred contract costs recorded on the consolidated balance sheet at December 31, 2025 and 2024.

Other Current Assets

Other current assets include amounts associated with Medicare Part D, rebates due from pharmaceutical manufacturers and other amounts due within one year. We accrue pharmaceutical rebates as they are earned based on contractual terms and usage of the product. The balance of pharmaceutical rebates receivable was $1.9 billion and $1.7 billion at December 31, 2025 and 2024, respectively.

In October 2024, we entered an uncommitted receivables purchase facility, or the Facility, under which certain pharmaceutical rebate receivables may be sold on a non-recourse basis to a financial institution. Although the sale is made without recourse, we provide collection services related to the transferred assets without compensation. The Facility's initial total capacity was $1.19 billion with a one year term, unless terminated early or extended. In October 2025, we extended the Facility for an additional one year term and updated its capacity to $1.09 billion. As control of, and risk related to, the receivables are transferred to the financial institution, the transactions under the Facility are accounted for as a true sale. The derecognition of our receivables transferred to a financial institution reduce our net pharmaceutical rebate receivable balance included in “Other current assets” on our accompanying consolidated balance sheets and generate a loss on discounted receivables included in “Operating costs” on our accompanying consolidated statements of income. As servicer of the purchased receivables, we establish a payable to the financial institution included in “Trade accounts payable and accrued expenses” on our accompanying consolidated balance sheets for rebates collected from manufacturers not yet remitted to the financial institution. Cash proceeds from the sale of receivables to the financial institution are classified as an operating activity included in “Changes in other assets” and rebates collected from manufacturers not yet remitted to the financial institution are classified as a financing activity included in “Changes in rebate factor payable” on our accompanying consolidated statement of cash flows. For the year ended December 31, 2025, we sold $1.5 billion of pharmaceutical rebate receivables under the Facility and the loss on discounted receivables was not material. During 2025, we collected $1.0 billion, of the $1.5 billion sold, from manufacturers and remitted back to the financial institution. For the year ended December 31, 2024, we sold $639 million of pharmaceutical rebate receivables under the Facility and the loss on discounted receivables was not material. As of December 31, 2024, we collected $168 million from manufacturers, $123 million of which had not been remitted to the financial institution. During 2025, the $123 million was remitted back to the financial institution and the remaining $471 million receivables sold were collected from the manufacturers and remitted back to the financial institution.

Policy Acquisition Costs

Policy acquisition costs are those costs that relate directly to the successful acquisition of new and renewal insurance policies. Such costs include commissions, costs of policy issuance and underwriting, and other costs we incur to acquire new business or renew existing business. We expensed policy acquisition costs related to our

Humana Inc.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Medicare Advantage prepaid health services policies as incurred. These short-duration Medicare Advantage prepaid health services policies typically have a 1-year term and may be canceled upon 30 days notice.

Long-Lived Assets

Property and equipment is recorded at cost. Gains and losses on sales or disposals of property and equipment are included in operating costs in our consolidated income statements. Certain costs related to the development or purchase of internal-use software are capitalized. Depreciation is computed using the straight-line method over estimated useful lives ranging from 3 to 10 years for equipment, 3 to 5 years for computer software, and 10 to 20 years for buildings. Improvements to leased facilities are depreciated over the shorter of the remaining lease term or the anticipated life of the improvement.

We periodically review long-lived assets, including property and equipment and other definite-lived intangible assets, for impairment whenever adverse events or changes in circumstances indicate the carrying value of the asset may not be recoverable. Losses are recognized for a long-lived asset to be held and used in our operations when the undiscounted future cash flows expected to result from the use of the asset are less than its carrying value. We recognize an impairment loss based on the excess of the carrying value over the fair value of the asset. A long-lived asset held for sale is reported at the lower of the carrying amount or fair value less costs to sell. Depreciation expense is not recognized on assets held for sale. Losses are recognized for a long-lived asset to be abandoned when the asset ceases to be used. In addition, we periodically review the estimated lives of all long-lived assets for reasonableness.

Equity Method Investments

We use the equity method of accounting for equity investments in companies where we are able to exercise significant influence, but not control, over operating and financial policies of the investee. Judgment regarding the level of influence over each equity method investment includes considering key factors such as our ownership interest, representation on the board of directors, organizational structure, participation in policy-making decisions and material intra-entity transactions.

Generally, under the equity method, original investments in these entities are recorded at cost and subsequently adjusted by our share of equity in income or losses after the date of acquisition as well as capital contributions to and distributions from these companies. Our proportionate share of the net income or loss of these companies is included in consolidated net income. Investment amounts in excess of our share of an investee’s net assets are amortized over the life of the related asset creating the excess. Excess goodwill is not amortized.

We evaluate equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable. Factors considered by us when reviewing an equity method investment for impairment include the length of time (duration) and the extent (severity) to which the fair value of the equity method investment has been less than carrying value, the investee’s financial condition and near-term prospects and the intent and ability to hold the investment for a period of time sufficient to allow for anticipated recovery. An impairment that is other-than-temporary is recognized in the period identified.

For additional information regarding our equity method investments, refer to Note 4.

Goodwill and Intangible Assets

Goodwill represents the unamortized excess of cost over the fair value of the net tangible and other intangible assets acquired. We are required to test at least annually for impairment at a level of reporting referred to as the reporting unit, and more frequently if adverse events or changes in circumstances indicate that the asset may be impaired. A reporting unit either is our operating segments or one level below the operating segments, referred to as a component, which comprise our reportable segments. A component is considered a reporting unit if the component constitutes a business for which discrete financial information is available that is regularly reviewed by management. We aggregate the components of an operating segment into one reporting unit if they have similar

Humana Inc.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

economic characteristics. Goodwill is assigned to the reporting units that are expected to benefit from the specific synergies of the business combination.

We perform a quantitative assessment to review goodwill for impairment to determine both the existence and amount of goodwill impairment, if any. Impairment tests are performed, at a minimum, in the fourth quarter of each year supported by our long-range business plan and annual planning process. We rely on an evaluation of future discounted cash flows to determine fair value of our reporting units. The fair value of our reporting units with significant goodwill exceeded carrying amounts. However, unfavorable changes in key assumptions or combinations of assumptions including a significant increase in the discount rate, decrease in the long-term growth rate or substantial reduction in our underlying cash flow assumptions, including revenue expectations and growth rates, operating cost trends, and projected operating income could have a significant negative impact on the estimated fair value of our home solutions reporting unit, which accounted for $4.4 billion of goodwill. Impairment tests completed for 2025, 2024, and 2023 did not result in an impairment loss.

Intangible assets with indefinite lives relate to Certificate of Needs (CON) and Medicare licenses acquired as part of our acquisition of CenterWell Home Health (formerly Kindred at Home) are included within other long-term assets in the consolidated balance sheet at December 31, 2025 and December 31, 2024. We are required to annually compare the fair values of other indefinite-lived intangible assets to their carrying amounts. If the carrying amount of an indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized. Fair values of indefinite-lived intangible assets are determined based on the income approach. For our CON intangible assets, unfavorable changes in key assumptions or combinations of assumptions, including a significant increase in the discount rate, decrease in the long-term growth rate or substantial reduction in the underlying cash flow assumptions, including revenue growth rates, operating cost trends, and projected operating income could have a significant negative impact on the estimated fair value of our CON intangible assets, which account for $790 million of our intangible assets. Impairment tests completed on our indefinite-lived intangible assets for 2025, 2024 and 2023 resulted in impairment charges of $128 million, $200 million and $55 million, respectively. These charges reflect the amount by which the carrying value exceeded its estimated fair value. The fair values of the assets were measured using Level 3 inputs, such as projected revenues and operating cash flows.

Definite-lived intangible assets primarily relate to acquired customer contracts/relationships and are included with other long-term assets in the consolidated balance sheets. Definite-lived intangible assets are amortized over the useful life generally using the straight-line method. We review definite-lived intangible assets for impairment under our long-lived asset policy.

Benefits Payable and Benefits Expense Recognition

Benefits expense includes claim payments, capitation payments, pharmacy costs net of rebates, allocations of certain centralized expenses and various other costs incurred to provide health insurance coverage to members, as well as estimates of future payments to hospitals and others for medical care and other supplemental benefits provided on or prior to the balance sheet date. Capitation payments represent monthly contractual fees disbursed to primary care and other providers who are responsible for providing medical care to members. Pharmacy costs represent payments for members’ prescription drug benefits, net of rebates from drug manufacturers. Receivables for such pharmacy rebates are included in other current assets in our consolidated balance sheets. Other supplemental benefits include dental, vision, and other supplemental health products.

We estimate the costs of our benefits expense payments using actuarial methods and assumptions based upon claim payment patterns, medical cost inflation, historical developments such as claim inventory levels and claim receipt patterns, and other relevant factors, and record benefit reserves for future payments. We continually review estimates of future payments relating to claims costs for services incurred in the current and prior periods and make necessary adjustments to our reserves.

Benefits expense is recognized in the period in which services are provided and includes an estimate of the cost of services which have been incurred but not yet reported, or IBNR. Our reserving practice is to consistently recognize the actuarial best point estimate within a level of confidence required by actuarial standards. Actuarial standards of practice generally require a level of confidence such that the liabilities established for IBNR have a

Humana Inc.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

greater probability of being adequate versus being insufficient. Therefore, in many situations, the claim amounts ultimately settled will be less than the estimate that satisfies the actuarial standards of practice.

We develop our estimate for IBNR using actuarial methodologies and assumptions, primarily based upon historical claim experience. Depending on the period for which incurred claims are estimated, we apply a different method in determining our estimate. For periods prior to the most recent two months, a completion factor method uses historical paid claims patterns to estimate the percentage of claims incurred during a given period that have historically been adjudicated as of the reporting period. Changes in claim inventory levels and known changes in claim payment processes are taken into account in these estimates. For the most recent two months, the incurred claims are estimated primarily from a trend analysis based upon per member per month claims trends developed from our historical experience in the preceding months, adjusted for known changes in estimates of hospital admissions, recent hospital and drug utilization data, provider contracting changes, changes in benefit levels, changes in member cost sharing, changes in medical management processes, product mix, and workday seasonality.

The completion factor method is used for the months of incurred claims prior to the most recent two months because the historical percentage of claims processed for those months is at a level sufficient to produce a consistently reliable result. Conversely, for the most recent two months of incurred claims, the volume of claims processed historically is not at a level sufficient to produce a reliable result, which therefore requires us to examine historical trend patterns as the primary method of evaluation. Changes in claim processes, including recoveries of overpayments, receipt cycle times, claim inventory levels, outsourcing, system conversions, and processing disruptions due to weather or other events affect views regarding the reasonable choice of completion factors. Claim payments to providers for services rendered are often net of overpayment recoveries for claims paid previously, as contractually allowed. Claim overpayment recoveries can result from many different factors, including retroactive enrollment activity, audits of provider billings, and/or payment errors. Changes in patterns of claim overpayment recoveries can be unpredictable and result in completion factor volatility, as they often impact older dates of service. The receipt cycle time measures the average length of time between when a medical claim was initially incurred and when the claim form was received. Increases in electronic claim submissions from providers decrease the receipt cycle time. If claims are submitted or processed on a faster (slower) pace than prior periods, the actual claim may be more (less) complete than originally estimated using our completion factors, which may result in reserves that are higher (lower) than required.

Medical cost trends potentially are more volatile than other segments of the economy. The drivers of medical cost trends include increases in the utilization of hospital facilities, physician services, new higher priced technologies and medical procedures, and new prescription drugs and therapies, as well as the inflationary effect on the cost per unit of each of these expense components. Other external factors such as government-mandated benefits or other regulatory changes, the tort liability system, increases in medical services capacity, direct to consumer advertising for prescription drugs and medical services, an aging population, lifestyle changes including diet and smoking, catastrophes, public health emergencies, epidemics and pandemics (such as COVID-19) also may impact medical cost trends. Internal factors such as system conversions, claims processing cycle times, changes in medical management practices and changes in provider contracts also may impact our ability to accurately predict estimates of historical completion factors or medical cost trends. All of these factors are considered in estimating IBNR and in estimating the per member per month claims trend for purposes of determining the reserve for the most recent two months. Additionally, we continually prepare and review follow-up studies to assess the reasonableness of the estimates generated by our process and methods over time. The results of these studies are also considered in determining the reserve for the most recent two months. Each of these factors requires significant judgment by management.

We reassess the profitability of our contracts for providing insurance coverage to our members when current operating results or forecasts indicate probable future losses. We establish a premium deficiency reserve in current operations to the extent that the sum of expected future costs, claim adjustment expenses, and maintenance costs exceeds related future premiums under contracts. For purposes of determining premium deficiencies, contracts are grouped in a manner consistent with our method of acquiring, servicing, and measuring the profitability of such contracts. Losses recognized as a premium deficiency result in a beneficial effect in subsequent periods as operating losses under these contracts are charged to the liability previously established. Because the majority of our member

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

contracts renew annually, we would not record a material premium deficiency reserve, except when unanticipated adverse events or changes in circumstances indicate otherwise.

We believe our benefits payable are adequate to cover future claims payments required. However, such estimates are based on knowledge of current events and anticipated future events. Therefore, the actual liability could differ materially from the amounts provided.

Future policy benefits payable

Future policy benefits payable includes liabilities for long-duration insurance policies primarily related to certain blocks of insurance assumed in acquisitions, primarily life and annuities in run-off status, and are included in our consolidated balance sheet within other long-term liabilities. Most of these policies are subject to reinsurance. For additional information regarding reinsurance, refer to Note 19.

Book Overdraft

Under our cash management system, checks issued but not yet presented to banks that would result in negative bank balances when presented are classified as a current liability in the consolidated balance sheets. Changes in book overdrafts from period to period are reported in the consolidated statement of cash flows as a financing activity.

Income Taxes

We recognize an asset or liability for the deferred tax consequences of temporary differences between the tax bases of assets or liabilities and their reported amounts in the consolidated financial statements. These temporary differences will result in taxable or deductible amounts in future years when the reported amounts of the assets or liabilities are recovered or settled. We also recognize the future tax benefits such as net operating and capital loss carryforwards as deferred tax assets. A valuation allowance is provided against these deferred tax assets if it is more likely than not that some portion or all of the deferred tax assets will not be realized. Future years’ tax expense may be increased or decreased by adjustments to the valuation allowance or to the estimated accrual for income taxes. Deferred tax assets and deferred tax liabilities are further adjusted for changes in the enacted tax rates.

We record tax benefits when it is more likely than not that the tax return position taken with respect to a particular transaction will be sustained. A liability, if recorded, is not considered resolved until the statute of limitations for the relevant taxing authority to examine and challenge the tax position has expired, or the tax position is ultimately settled through examination, negotiation, or litigation. We classify interest and penalties associated with uncertain tax positions in our provision for income taxes.

Noncontrolling Interests

The consolidated financial statements include all assets, liabilities, revenues and expenses of less than 100% owned affiliates that we control. Accordingly, we record noncontrolling interests in the earnings and equity of such entities. We record adjustments to noncontrolling interests for the allocable portion of income or loss to which the noncontrolling interest holders are entitled based upon their portion of the subsidiaries they own. Distributions to holders of noncontrolling interests are adjusted to the respective noncontrolling interest holders’ balances. Noncontrolling interests, which relate to the minority ownership held by third-party investors in certain of our businesses within our Insurance and CenterWell segments, are reported below net income under the heading “Net (income) loss attributable to noncontrolling interests” in the consolidated statements of income and presented as a component of equity in the consolidated balance sheets.

Stock-Based Compensation

We generally recognize stock-based compensation expense, as determined on the date of grant at fair value, on a straight-line basis over the period during which an employee is required to provide service in exchange for the award (the vesting period). In addition, for awards with both time and performance-based conditions, we generally recognize compensation expense on a straight line basis over the vesting period when it is probable that the

Humana Inc.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

performance condition will be achieved. We estimate expected forfeitures and recognize compensation expense only for those awards which are expected to vest. We estimate the grant-date fair value of stock options using the Black-Scholes option-pricing model.

For additional information regarding our stock-based compensation plans, refer to Note 14.

Earnings Per Common Share

We compute basic earnings per common share on the basis of the weighted-average number of unrestricted common shares outstanding. Diluted earnings per common share is computed on the basis of the weighted-average number of unrestricted common shares outstanding plus the dilutive effect of outstanding employee stock options and restricted shares, or units, using the treasury stock method.

For additional information regarding our earnings per share, refer to Note 15.

Fair Value

Assets and liabilities measured at fair value are categorized into a fair value hierarchy based on whether the inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our own assumptions about the assumptions market participants would use. The fair value hierarchy includes three levels of inputs that may be used to measure fair value as described below.

Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 1 assets and liabilities include securities that are traded in an active exchange market.

Level 2 – Observable inputs other than Level 1 prices such as quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments as well as debt securities whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data.

Level 3 – Unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. Level 3 includes assets and liabilities whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques reflecting our own assumptions about the assumptions market participants would use as well as those requiring significant management judgment.

Fair value of actively traded debt and equity securities are based on quoted market prices. Fair value of other debt securities are based on quoted market prices of identical or similar securities or based on observable inputs like interest rates generally using a market valuation approach, or, less frequently, an income valuation approach and are generally classified as Level 2. Fair value of privately held investment grade debt securities are estimated using a variety of valuation methodologies, including both market and income approaches, where an observable quoted market does not exist and are generally classified as Level 3. For privately-held investment grade debt securities, such methodologies include reviewing the value ascribed to the most recent financing, comparing the security with securities of publicly-traded companies in similar lines of business with similar credit characteristics, and reviewing the underlying financial performance including estimating discounted cash flows.

We obtain at least one price for each security from a third-party pricing service. These prices are generally derived from recently reported trades for identical or similar securities, including adjustments through the reporting date based upon observable market information. When quoted prices are not available, the third-party pricing service may use quoted market prices of comparable securities or discounted cash flow analysis, incorporating inputs that are currently observable in the markets for similar securities. Inputs that are often used in the valuation methodologies include benchmark yields, reported trades, credit spreads, broker quotes, default rates, and

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

prepayment speeds. We are responsible for the determination of fair value and as such we perform analysis on the prices received from the third-party pricing service to determine whether the prices are reasonable estimates of fair value. Our analysis includes a review of monthly price fluctuations as well as a quarterly comparison of the prices received from the pricing service to prices reported by our third-party investment adviser. In addition, on a quarterly basis we examine the underlying inputs and assumptions for a sample of individual securities across asset classes, credit rating levels, and various durations.

Recently Issued Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In December 2023, the FASB issued Accounting Standards Update No. 2023-09 — Income Taxes (Topic 740): Improvements to Income Tax Disclosures, effective for annual 2025 year-end financial statements. The updated guidance requires additional disclosure and disaggregated information in the income tax rate reconciliation along with qualitative explanation of individually significant reconciling items. The updated guidance also requires disclosure of the income taxes paid (net of refunds received) disaggregated by jurisdiction. Our income tax footnote was updated to reflect the adoption of the standard, which did not have a material impact on our disclosures.

Accounting Pronouncements Effective in Future Periods

In November 2024, the FASB issued Accounting Standards Update No. 2024-03 — Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The new guidance requires significant additional disclosures disaggregating certain costs and expenses including purchases of inventory, employee compensation, depreciation, and intangible asset amortization. The new guidance requires prospective application (with retrospective application permitted). The new guidance will be effective for us beginning with our annual 2027 year-end financial statements, with early adoption permitted. We are currently evaluating the impact on our disclosures.

In September 2025, the FASB issued Accounting Standards Update No. 2025-06 — Intangibles — Goodwill and Other — Internal Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. The new guidance modernizes consideration of different methods of software development, updating the requirements for capitalization of software costs. The new guidance requires prospective application (with retrospective application permitted). The new guidance will be effective for us beginning with our interim 2028 financial statements, with early adoption permitted. We are currently evaluating the impact on our consolidated results of operations, financial position, and cash flows.

There are no other recently issued accounting standards that apply to us or that are expected to have a material impact on our results of operations, financial condition, or cash flows.

3. ACQUISITIONS AND DIVESTITURES

During 2025, 2024, and 2023, we acquired various health and wellness related businesses, and divested of a business during 2025, that individually or in the aggregate, have not had a material impact on our results of operations, financial condition, or cash flows. The results of operations and financial condition of these businesses acquired have been included in our consolidated statements of income and consolidated balance sheets from the respective acquisition dates. Acquisition and divestiture related costs recognized in 2025, 2024 and 2023 were not material to our results of operations. For asset acquisitions, the goodwill acquired is partially amortizable as deductible expenses for tax purposes. The pro forma financial information assuming the acquisitions had occurred as of the beginning of the calendar year prior to the year of acquisition, as well as the revenues and earnings generated during the year of acquisition, was not material for disclosure purposes.

On February 13, 2026, we completed the acquisition of a primary care business for consideration of approximately $941 million.

4. EQUITY METHOD INVESTMENTS

We completed the sale of a 60% interest in Gentiva Hospice on August 11, 2022 and we account for our remaining minority ownership in Gentiva Hospice using the equity method of accounting. At December 31, 2025 and 2024, we owned approximately 35%. This investment was reflected in equity method investments in our December 31, 2025 and 2024 consolidated balance sheets, with our share of loss reported as equity in net losses in our consolidated statements of income for the years ended December 31, 2025, 2024, and 2023.

The summarized balance sheets at December 31, 2025 and 2024 and statements of income for the years ended December 31, 2025, 2024, and 2023 of Gentiva Hospice were as follows:

Our primary care business previously entered into a strategic partnership with Welsh, Carson, Anderson & Stowe, or WCAS, to accelerate the expansion of our primary care model through the development of clinics. As of December 31, 2025, there were 146 primary care clinics operating under the partnership. In addition, the agreements include a series of put and call options through which WCAS may require us to purchase their interest in the entity, and through which we may acquire WCAS’s interest, over the next 1 to 9 years. We have the option to purchase the first two cohorts of clinics in 2026 for approximately $1.0 billion to $1.5 billion based on current projections. All existing cohorts can be called by us from 2026 to 2033 or put to us by WCAS from 2027 to 2034 and could require $3.0 billion to $5.0 billion to purchase based on current projections. These estimates are dependent on multiple factors including the actual timing of when the put or call options are exercised, expected revenue growth at each center within the respective cohort and future capital contributions, among other factors. For additional information on inputs relevant to these put and call options, refer to Note 6.

Other equity method investments

We have several other individually immaterial equity method investments included within equity method investments in our consolidated balance sheets as of December 31, 2025 and 2024 with our share of income or loss reported as equity in net losses in our consolidated statements of income for the years ended December 31, 2025, 2024 and 2023.

We own certain corporate debt securities of Gentiva Hospice. The book value and fair value are $381 million and $383 million, respectively, at December 31, 2025. The book value and fair value were $381 million and $396 million, respectively, at December 31, 2024.

We participate in a securities lending program where we loan certain investment securities for short periods of time in exchange for collateral, consisting of cash or U.S. Government securities, initially equal to at least 102% of the fair value of the investment securities on loan. Collateral with a fair value of $638 million was held at December 31, 2025. At December 31, 2025, collateral from lending our investment securities was reinvested in short-term, highly liquid assets. In addition, we participated in non-cash securities lending with a fair value of $193 million at December 31, 2025.

Gross unrealized losses and fair values aggregated by investment category and length of time of individual debt securities that have been in a continuous unrealized loss position for which no allowances for credit loss has been recorded were as follows at December 31, 2025 and 2024, respectively:

Approximately 97% of our debt securities were investment-grade quality, with a weighted average credit rating of AA- by Standard & Poor's Rating Service, or S&P at December 31, 2025. Our remaining debt securities below investment grade were primarily rated B. Tax-exempt municipal securities were diversified among general

Humana Inc.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

obligation bonds of states and local municipalities in the United States as well as special revenue bonds issued by municipalities to finance specific public works projects such as utilities, water and sewer, transportation, or education. Our general obligation bonds are diversified across the United States with no individual state exceeding approximately 1% of our total debt securities. Our investment policy limits investments in a single issuer and requires diversification among various asset types.

Our unrealized losses from all debt securities were generated from approximately 1,150 positions out of a total of approximately 2,110 positions at December 31, 2025. All issuers of debt securities we own that were trading at an unrealized loss at December 31, 2025 remain current on all contractual payments. After taking into account these and other factors previously described, we believe these unrealized losses primarily were caused by an increase in market interest rates in the current markets since the time these debt securities were purchased. At December 31, 2025, we did not intend to sell any debt securities with an unrealized loss position in accumulated other comprehensive income, and it is not likely that we will be required to sell these debt securities before recovery of their amortized cost basis. Additionally, we did not record any material credit allowances for debt securities that were in an unrealized loss position at December 31, 2025, 2024 or 2023.

The detail of (losses) gains related to investment securities and included within investment income was as follows for the years ended December 31, 2025, 2024, and 2023:
