Description of Business	Description of Business Overview Unless the context dictates otherwise, references in these notes to the financial statements to the “Company,” “we,” “us,” “our,” and similar words are references to Astrana Health, Inc. (“Astrana”), formerly known as Apollo Medical Holdings, Inc., and its consolidated subsidiaries and affiliated entities, as appropriate, including its consolidated variable interest entities (“VIEs”). Headquartered in Alhambra, California, Astrana is a leading provider-centric, technology-powered, risk-bearing healthcare company. Leveraging its proprietary end-to-end technology solutions, Astrana operates an integrated healthcare delivery platform that enables providers to successfully participate in value-based care arrangements, thus empowering them to deliver accessible, high-quality care to patients in a cost-effective manner. Together with Astrana’s affiliated physician groups and consolidated subsidiaries and VIEs, the Company provides value-based care enablement services and care delivery with its consolidated care partners to serve patients in California, Nevada, and Texas, the majority of whom are covered by private or public insurance provided through Medicare, Medicaid, and health maintenance organizations (“HMOs”), with a small portion of our revenue coming from non-insured patients. The Company provides care coordination services to each major constituent of the healthcare delivery system, including patients, families, primary care physicians, specialists, acute care hospitals, alternative sites of inpatient care, physician groups, and health plans. The Company’s physician network consists of primary care physicians, specialist physicians, physician and specialist extenders, and hospitalists. Segments The Company’s three reportable segments are Care Partners, Care Delivery and Care Enablement, which are described as follows: Care Partners The Care Partners segment is focused on building and managing high-quality and high-performance provider networks by partnering with, empowering, and investing in strong provider partners aligned on a shared vision for coordinated care delivery. By leveraging the Company’s unique care enablement platform and ability to recruit, empower, and incentivize physicians to effectively manage total cost of care, the Company is able to organize partnered providers into successful multi-payer risk-bearing organizations that take on varying levels of risk based on total cost of care across membership in all lines of business, including Medicare fee for service (“FFS”), Medicare Advantage, Medicaid, Commercial, and Exchange. Through the Company’s network of “independent practice associations” (“IPAs”), “accountable care organizations” (“ACOs”), and Restricted Knox-Keene licensed health plan, the Company’s healthcare delivery entities are responsible for coordinating and delivering high-quality care to the Company’s patients and ensuring continuity of care in Astrana’s ecosystem across age, stage of life, or life circumstance. Beginning in 2024, in addition to participating in the ACO REACH Model, the Company began participating in the Medicare Shared Savings Program (“MSSP”). The MSSP was created to promote accountability and improve coordination of care for Medicare beneficiaries. Care Delivery The Company’s Care Delivery segment is a patient-centric, data-driven care delivery organization focused on delivering high-quality and accessible care to all patients. The Company’s care delivery organization includes primary care, multi-specialty care, and ancillary care services. This segment includes the following: •Primary care clinics, including post-acute care services; •Multi-specialty care clinics and medical groups, including hospitalist, intensivist, and physician advisory services, cardiac care and diagnostic testing, and specialized care for women’s health; and •Ancillary service providers, such as urgent care centers, outpatient imaging centers, ambulatory surgery centers, and full-service labs. Care Enablement The Company’s Care Enablement segment is an integrated, end-to-end clinical, operational, financial, and administrative platform powered by the Company’s proprietary technology suite that enhances the delivery of high-quality, value-based care to patients and leads to superior clinical and financial outcomes. The Company provides solutions to providers, including independent physicians, provider and medical groups, accountable care organizations, and payers, including health plans and other risk-bearing organizations. The Company’s platform meets providers and payers where they are, with a wide spectrum of solutions across the total cost of care risk spectrum, ranging from solutions for fee-for-service entities to hospital-shared risk-bearing entities, and across patient types, including Medicare, Medicaid, Commercial, and Exchange patients. This segment includes the Company’s wholly owned subsidiaries which operate as management services organizations (“MSOs”), which enter into long-term management and/or administrative services agreements with IPAs, ACOs, clinics, or independent providers. By leveraging the Company’s care enablement platform, providers and payers can improve their ability to deliver high-quality care to their patients and achieve better patient outcomes.
