General	1. General Basis of Presentation The consolidated financial statements of Magellan Health, Inc., a Delaware corporation (“Magellan”), include Magellan and its subsidiaries (together with Magellan, the “Company”). All significant intercompany accounts and transactions have been eliminated in consolidation. On December 31, 2020, Magellan Health, Inc. (the “Company”) completed the sale of its Magellan Complete Care business (the “MCC Business”) to Molina Healthcare, Inc. (“Molina”), pursuant to a Stock and Asset Purchase Agreement, dated as of April 30, 2020, by and between the Company and Molina, for cash in the amount of $850 million plus closing adjustments of $158 million (subject to post-closing adjustments, if any), and the assumption by Molina of liabilities of the MCC Business (the “MCC Sale”). The MCC Business was the Company’s business of contracting with state Medicaid agencies and the U.S. Centers for Medicare and Medicaid Services to manage total medical benefits or long-term support services for Medicaid and dual eligible Medicaid and Medicare populations. On January 4, 2021, the Company and Centene Corporation (“Centene”) entered into an Agreement of Plan of Merger (the “Merger Agreement”) by and among the Company, Centene, and Mayflower Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Centene (“Merger Sub”), pursuant to which, subject to the terms and conditions set forth therein, Merger Sub will merge with and into the Company, with the Company surviving such merger as a wholly-owned subsidiary of Centene. The Company expects to complete the transaction in the second half of 2021. Business Overview The Company provides managed care and pharmacy solutions for some of the most complex areas of healthcare. The Company offers innovative solutions that combine analytics, technology and clinical rigor to drive better decision making, positively impact members’ health outcomes and optimize the cost of care for the customers Magellan serves. The Company provides services to health plans and other managed care organizations (“MCOs”), employers, labor unions, various military and governmental agencies and third-party administrators (“TPAs”). Magellan operates three segments: Healthcare, Pharmacy Management and Corporate. Healthcare Segment The Healthcare segment (“Healthcare”) previously consisted of two reporting units – Behavioral & Specialty Health and Magellan Complete Care (“MCC”). As a result of the sale of the MCC Business to Molina, the Healthcare segment now only includes the Behavioral and Specialty Health reporting unit. The Behavioral & Specialty Health reporting unit’s customers include health plans, accountable care organizations (“ACOs”), employers, the United States military and various federal government agencies for whom Magellan provides carve-out management services for (i) behavioral health, (ii) employee assistance plans (“EAP”) and (iii) other areas of specialty healthcare including diagnostic imaging, musculoskeletal management, cardiac and physical medicine. These management services can be applied broadly across commercial, Medicaid and Medicare populations, or on a more targeted basis for our health plans and ACO customers. The Behavioral & Specialty Health unit also includes Magellan’s carve-out behavioral health contracts with various state Medicaid agencies, as well as certain provider assets that deliver primary care and behavioral healthcare services through an integrated approach. The MCC Business, which is now reflected as discontinued operations, contracts with state Medicaid agencies and the Centers for Medicare and Medicaid Services (“CMS”) to manage care for beneficiaries under various Medicaid and Medicare programs. MCC manages a wide range of services from total medical cost to carve out long-term support services. MCC largely focuses on managing care for more acute special populations including individuals with serious mental illness (“SMI”), dual eligibles, aged, blind and disabled (“ABD”) and other populations with unique and often complex healthcare needs. Magellan’s coordination and management of these healthcare and long-term support services are provided through its comprehensive network of medical and behavioral health professionals, clinics, hospitals, skilled nursing facilities, home care agencies and ancillary service providers. This network of credentialed providers is integrated with clinical and quality improvement programs to improve access to care and enhance the healthcare experience for individuals in need of care, while at the same time making the cost of these services more affordable for our customers. In addition to the Company’s provider assets where it provides treatment services in certain geographies, the Company also employs licensed behavioral health counselors to deliver non-medical counseling under certain government contracts. The Company provides its Healthcare management services primarily through: (i) risk-based contractual arrangements, where the Company assumes all or a substantial portion of the responsibility for the cost of providing treatment services in exchange for a fixed per member per month (“PMPM”) fee, or (ii) administrative services only (“ASO”) contractual arrangements, where the Company provides services such as utilization review, claims administration and/or provider network management, but does not assume full responsibility for the cost of the treatment services, in exchange for an administrative fee and, in some instances, a gain share. Pharmacy Management The Pharmacy Management segment (“Pharmacy Management”) is comprised of services that provide clinical and financial management of pharmaceuticals paid under both the medical and the pharmacy benefit. Pharmacy Management’s customer solutions include: (i) pharmacy benefit management (“PBM”) services, including pharmaceutical dispensing operations and Medicare Part D; (ii) pharmacy benefit administration (“PBA”) for state Medicaid and other government sponsored programs; (iii) clinical and formulary management programs; (iv) medical pharmacy management programs; and (v) programs for the integrated management of specialty drugs across both the medical and pharmacy benefit that treat complex conditions, regardless of site of service, method of delivery, or benefit reimbursement. These services are available individually, in combination, or in a fully integrated manner. The Company markets its pharmacy management services to managed care organizations, employers, third party administrators, state governments, Medicare Part D, and other government agencies, exchanges, brokers and consultants. In addition, the Company will continue to upsell its pharmacy services to its existing customers and market its pharmacy solutions to the Healthcare customer base. Pharmacy Management contracts with its customers for services using risk-based, gain share or ASO arrangements. In addition, Pharmacy Management provides services to the Healthcare segment for most of the MCC business. On May 11, 2020, the Company announced its decision to exit the Medicare Part D business at the end of 2020. The Company will retain its Medicare Employer Group Waiver Plan as well as full capabilities to serve the PBM needs of its existing and prospective Medicare customers. Corporate This segment of the Company is comprised primarily of amounts not allocated to the Healthcare and Pharmacy Management segments that are largely associated with costs related to being a publicly traded company.

Business Overview

The Company provides managed care and pharmacy solutions for some of the most complex areas of healthcare. The Company offers innovative solutions that combine analytics, technology and clinical rigor to drive better decision making, positively impact members’ health outcomes and optimize the cost of care for the customers Magellan serves. The Company provides services to health plans and other managed care organizations (“MCOs”), employers, labor unions, various military and governmental agencies and third-party administrators (“TPAs”). Magellan operates three segments: Healthcare, Pharmacy Management and Corporate.

Healthcare Segment

The Healthcare segment (“Healthcare”) previously consisted of two reporting units – Behavioral & Specialty Health and Magellan Complete Care (“MCC”). As a result of the sale of the MCC Business to Molina, the Healthcare segment now only includes the Behavioral and Specialty Health reporting unit.

The Behavioral & Specialty Health reporting unit’s customers include health plans, accountable care organizations (“ACOs”), employers, the United States military and various federal government agencies for whom Magellan provides carve-out management services for (i) behavioral health, (ii) employee assistance plans (“EAP”) and (iii) other areas of specialty healthcare including diagnostic imaging, musculoskeletal management, cardiac and physical medicine. These management services can be applied broadly across commercial, Medicaid and Medicare populations, or on a more targeted basis for our health plans and ACO customers. The Behavioral & Specialty Health unit also includes Magellan’s carve-out behavioral health contracts with various state Medicaid agencies, as well as certain provider assets that deliver primary care and behavioral healthcare services through an integrated approach.

The MCC Business, which is now reflected as discontinued operations, contracts with state Medicaid agencies

and the Centers for Medicare and Medicaid Services (“CMS”) to manage care for beneficiaries under various Medicaid and Medicare programs. MCC manages a wide range of services from total medical cost to carve out long-term support services. MCC largely focuses on managing care for more acute special populations including individuals with serious mental illness (“SMI”), dual eligibles, aged, blind and disabled (“ABD”) and other populations with unique and often complex healthcare needs.

Magellan’s coordination and management of these healthcare and long-term support services are provided through its comprehensive network of medical and behavioral health professionals, clinics, hospitals, skilled nursing facilities, home care agencies and ancillary service providers. This network of credentialed providers is integrated with clinical and quality improvement programs to improve access to care and enhance the healthcare experience for individuals in need of care, while at the same time making the cost of these services more affordable for our customers. In addition to the Company’s provider assets where it provides treatment services in certain geographies, the Company also employs licensed behavioral health counselors to deliver non-medical counseling under certain government contracts.

The Company provides its Healthcare management services primarily through: (i) risk-based contractual arrangements, where the Company assumes all or a substantial portion of the responsibility for the cost of providing treatment services in exchange for a fixed per member per month (“PMPM”) fee, or (ii) administrative services only (“ASO”) contractual arrangements, where the Company provides services such as utilization review, claims administration and/or provider network management, but does not assume full responsibility for the cost of the treatment services, in exchange for an administrative fee and, in some instances, a gain share.
