Direct Answer

UnitedHealth Group Incorporated (NYSE: UNH) reported total revenues of approximately $400.3 billion in fiscal year 2024 (the calendar year ending December 31, 2024), making it the largest healthcare company in the world by revenue. The company operates two segments: UnitedHealthcare (health insurance, approximately $298 billion in revenues) and Optum (health services, approximately $102 billion in revenues). Net earnings attributable to shareholders were approximately $14.4 billion. Diluted GAAP EPS was approximately $15.10; adjusted (non-GAAP) diluted EPS was approximately $27.66. Operating margin was approximately 5.1%, which is thin by cross-sector standards but typical for managed care organizations whose revenues are gross premiums. A ransomware attack on the Change Healthcare subsidiary in February 2024 caused approximately $870 million in direct costs and disrupted pharmacy claims processing nationwide for several weeks.

Business segments (FY2024)

SegmentFY2024 revenues (approx.)Key sub-businessesMembers / customers served
UnitedHealthcare ~$298B Employer & Individual (commercial plans); Medicare & Retirement (Medicare Advantage, Medicare Supplement); Medicaid managed care; Global (Brazil, UK) ~49.4 million members
Optum ~$102B OptumHealth (physician groups, value-based care); OptumInsight (analytics, technology, revenue cycle, Change Healthcare); OptumRx (pharmacy benefit management) ~22M patients (OptumHealth); ~67M people (OptumRx)

UnitedHealthcare is the health insurance arm of the enterprise. It covers employer-sponsored commercial plans for working-age individuals and their dependents, individual marketplace plans, Medicare Advantage (the privately administered alternative to traditional Medicare), Medicare Supplement (Medigap), and Medicaid managed care contracts administered on behalf of state governments. UnitedHealthcare is the largest Medicare Advantage insurer in the United States by enrollment. Its global division offers health insurance in Brazil (Amil) and the United Kingdom, among other markets.

Optum is the health services arm and operates across three distinct businesses. OptumHealth employs or affiliates with physician groups and care delivery networks, focusing on value-based care arrangements where payment is tied to patient outcomes rather than fee-for-service volume. OptumInsight provides data analytics, technology platforms, and revenue cycle management services to hospitals, health systems, and government agencies. OptumRx is a pharmacy benefit manager (PBM) that administers prescription drug benefits on behalf of health plan sponsors, negotiating drug prices and managing formularies for approximately 67 million people. Optum generates higher operating margins than UnitedHealthcare, reflecting the different cost structures of services versus insurance underwriting.

Key financial metrics (FY2023 vs. FY2024)

MetricFY2023FY2024

UnitedHealthcare revenues~$281B~$298B
Optum revenues~$91B~$102B
Operating income~$22.4B~$20.4B

Total revenues grew from approximately $371.6 billion in FY2023 to approximately $400.3 billion in FY2024, an increase of approximately 7.7%. However, GAAP net earnings fell sharply from approximately $22.4 billion in FY2023 to approximately $14.4 billion in FY2024, primarily because FY2023 included significant gains from asset sales and divestitures that did not recur, while FY2024 absorbed the direct costs of the Change Healthcare cybersecurity incident (approximately $870 million) plus elevated medical cost ratios across the commercial and Medicare Advantage books of business.

The gap between GAAP diluted EPS ($15.10) and adjusted diluted EPS ($27.66) in FY2024 reflects the company's non-GAAP adjustments, which primarily exclude amortization of intangible assets acquired in transactions such as the Change Healthcare acquisition, restructuring charges, and the direct costs of the cybersecurity incident. Investors should read UnitedHealth Group's SEC filings directly to understand the full reconciliation between GAAP and non-GAAP figures.

Operating margin of approximately 5.1% in FY2024 looks narrow compared to many sectors, but this is characteristic of managed care organizations, where revenues consist largely of gross insurance premiums and medical costs represent the largest expense. A medical care ratio (the share of premium revenue paid out as medical claims) of around 85% leaves limited margin for administrative costs, operating income, and earnings. Small changes in the medical care ratio have a large dollar impact on earnings because the premium revenue base is so large.

Change Healthcare cybersecurity incident (February 2024)

In February 2024, Change Healthcare, a unit within UnitedHealth Group's OptumInsight business, suffered a ransomware attack that disrupted pharmacy claims processing, clinical decision support, and revenue cycle management services across the U.S. healthcare system for several weeks. The attack affected pharmacies, hospitals, physician practices, and other healthcare providers that relied on Change Healthcare's clearinghouse and payment processing platforms to submit and receive reimbursement for patient care.

UnitedHealth Group acquired Change Healthcare in 2022 for approximately $7.8 billion, following a period of antitrust scrutiny. The February 2024 incident was the largest confirmed cyberattack on a U.S. healthcare entity by systemic impact at the time of its occurrence.

The company reported that the direct financial impact of the incident was approximately $870 million in FY2024. This figure included costs such as rebuilding and securing the affected systems, providing assistance to healthcare providers and pharmacies that experienced payment disruptions, and responding to regulatory inquiries. Business disruption costs to providers, insurers, and patients across the broader healthcare system extended beyond the amounts recorded on UnitedHealth Group's income statement and were not fully quantifiable from the company's own financial disclosures.

Regulatory and congressional scrutiny of the incident continued through 2024 and into 2025. The U.S. Department of Health and Human Services investigated whether the breach violated HIPAA protections for protected health information. UnitedHealth Group's disclosures to the SEC regarding the incident are publicly available through the SEC EDGAR system.

Optum's role as a diversification strategy

UnitedHealth Group has built Optum over more than a decade as a distinct health services business that generates revenues separately from health insurance premiums. This structure gives the enterprise two revenue streams with different margin profiles and different sensitivities to regulatory and competitive pressures.

Insurance underwriting (UnitedHealthcare) is subject to annual rate negotiations with employers and regulators, medical cost trends that are only partially predictable, and regulatory requirements such as minimum medical loss ratios under the Affordable Care Act. OptumHealth's value-based care contracts shift some financial risk from fee-for-service patterns toward capitated or risk-sharing arrangements, which reward the physician network for keeping patients healthy rather than for volume of procedures. OptumInsight's analytics and technology clients include competitors of UnitedHealthcare, which creates a structural separation: OptumInsight is intended to function as a healthcare IT company that serves the broader market, not only as a captive vendor. OptumRx negotiates rebates and formulary placement on behalf of its plan sponsor clients, and the economics of pharmacy benefit management have attracted significant legislative attention regarding how those rebates are structured and shared.

Optum's operating margin of approximately 7 to 8 percent in FY2024 exceeded UnitedHealthcare's operating margin, reflecting the lower capital requirements and less volatile cost structure of services-oriented businesses relative to insurance underwriting at scale. The combined enterprise uses earnings from Optum to partly offset variability in insurance underwriting results across different coverage years.

Dividend history and policy

UnitedHealth Group paid a quarterly dividend of $2.10 per share as of FY2024, equivalent to $8.40 per share on an annualized basis. At a share price of approximately $560, the dividend yield was approximately 1.5%. The company has increased its dividend for more than 15 consecutive years.

Dividend decisions are made by the board of directors and are not guaranteed. Investors seeking the current dividend rate and payment schedule should consult UnitedHealth Group's investor relations materials or SEC filings rather than relying on any figure that may have been superseded by a subsequent board action.
