PART I

Overview

Apollo Medical Holdings, Inc. is a leading physician-centric, technology-powered, risk-bearing healthcare company. Leveraging its proprietary end-to-end technology solutions, ApolloMed operates an integrated healthcare delivery platform that enables providers to successfully participate in value-based care arrangements, thus empowering them to deliver high-quality care to patients in a cost-effective manner. We, together with our affiliated physician groups and consolidated entities, are a physician-centric integrated population health management company providingprovide coordinated outcomes-based medical care in a cost-effective manner andprimarily serving patients in California, 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. We provide 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. Our physician network consists of primary care physicians, specialist physicians, physician and specialist extenders, and hospitalists. We operate primarily through Apollo Medical Holdings, Inc. (“ApolloMed”)ApolloMed and the following subsidiaries: Network Medical Management, Inc. (“NMM”), Apollo Medical Management, Inc. (“AMM”), APAACO and Apollo Care Connect, Inc. (“Apollo Care Connect”),APAACO, and their consolidated entities, including consolidated VIEs.

Led by a management team with several decades of experience, we have built a company and culture that is focused on physicians providing high-quality medical care, population health management, and care coordination for patients. WeAs a result, we are well-positioned to take advantage of the growing trendsshift in the U.S. healthcare industry towardstoward providing value-based and results-oriented healthcare focusingwith a focus on the triple aim of patient satisfaction, high-quality care, and cost efficiency.

Through our NGACO modelIn December 2017, ApolloMed merged with NMM, a California corporation formed in 1994 (the “2017 Merger”). As a result of the 2017 Merger, NMM became a wholly owned subsidiary of ApolloMed. The combined company operates under the Apollo Medical Holdings, Inc. name, but NMM is the larger entity in terms of assets, revenues, and a networkearnings. In addition, as of independentthe closing of the 2017 Merger, the majority of the board of directors of the combined company was comprised of former NMM directors and directors nominated for election by NMM. Accordingly, ApolloMed is considered to be the legal acquirer (and accounting acquiree), whereas NMM is considered to be the accounting acquirer (and legal acquiree).

Through our accountable care organization (“ACO”) and network of IPAs with more than 7,000approximately 11,000 contracted physicians,healthcare providers, which physician groups have agreements with various health plans, hospitals, and other HMOs, we are responsible for coordinating the care for over 980,000of approximately 1.3 million patients, in California, as of December 31, 2019.2022. These covered patients are comprised of managed care members whose health coverage is provided through their employers, or who have acquired health coverage directly from a health plan or as a result of their eligibility for Medicaid or Medicare benefits. Our managed patients benefit from an integrated approach that places physicians at the center of patient care and utilizes sophisticated risk management techniques and clinical protocols to provide high-quality, cost effectivecost-effective care. To implement a patient-centered, physician-centric experience, we also have other integrated and synergistic operations, including (i) management service organizations (“MSOs”)MSOs that provide management and other services to our affiliated IPAs, (ii) outpatient clinics, and (iii) hospitalists that coordinate the care of patients in hospitals.

If an entity is determined to be a VIE, we evaluate whether we are the primary beneficiary. The primary beneficiary analysis is a qualitative analysis based on power and benefits. We consolidate a VIE if we have both power and benefits – that is, (i) we have the power to direct the activities of a VIE that most significantly influence the VIE’s economic performance, and (ii) we have the obligation to absorb losses of, or the right to receive benefits from, the VIE that could potentially be significant to the VIE. See Note 18 – “Variable Interest Entities (VIEs)” to our consolidated financial statements for information on our entities

Some states have laws that prohibit business entities with non-physician owners from practicing medicine, which are generally referred to as the corporate practice of medicine laws. States that have corporate practice of medicine laws require that only physicians tocan practice medicine, exercise control over medical decisions, or engage in certain arrangements with other physicians, such as fee-splitting. California is a corporate practice of medicine state.

Therefore, in addition to our subsidiaries, we mainly operate by maintaining long-term MSAs with our affiliated IPAs, which are owned and operated by a network of independent primary care physicians and specialists, and which employ or contract with additional physicians to provide medical services. Under such agreements, we provide and perform non-medical management and administrative services, including financial management, information systems, marketing, risk management, and administrative support.

NMM has entered into MSAs with several affiliated IPAs, including Allied Physicians of California IPA d.b.a. Allied Pacific of California IPA (“APC”), Alpha Care Medical Group, Inc.

In return, APC Alpha Care, and Accountable Health Care arrangearranges for the delivery of health carehealthcare services by contracting with physicians or professional medical corporations for primary care and specialty care services. APC Alpha Care, and Accountable Health Care assumeassumes the financial risk of the cost of delivering health carehealthcare services in excess of the fixed amounts received. The risk is subject to stop-loss provisions in contracts with HMOs. Some risk is transferred to the contracted physicians or professional corporations. The physicians in the IPA are exclusively in control of, and responsible for, all aspects of the practice of medicine for enrolled patients. In accordance with relevant accounting guidance, APC Alpha Care, and Accountable Health Care, havehas been determined to be VIEsa VIE of NMM, as NMM is theirits primary beneficiary with the ability, through majority representation on the APC Joint Planning Board and otherwise, to direct the activities (excluding clinical decisions) that most significantly affect theirAPC’s economic performance.

Our Industry

U.S. healthcare spending has increased steadily over the past 20 years. According toapproximately two decades. CMS the estimatedestimates that total U.S. healthcare expenditures are expected to grow by 5.5%at an average annual rate of 5.1% from 20182021 to 20272030 and towill reach $6.0$6.8 trillion by 2027.2030. Health spending is projected to grow 0.8%1.8% faster than the U.S. gross domestic product per year on average over the 2018-2027 projection period,2021-2030, and as a result, the healthcare share of gross domestic product is expected to risestay consistent from 17.9%19.7% in 20172020 to 19.4% by 2027.19.6% in 2030. Medicare spending increased 6.4%by 8.4% to $750.2$900.8 billion and Medicaid spending increased by 3.0%9.2% to $597.4$734.0 billion in 2018,2021, which accounted for 21% and 16%17% of total health expenditures, respectively. Private health insurance spending increased by 5.8% to $1.2 trillion in 2018,2021, accounting for 34%28% of total health expenditures. Growth in Medicare (7.4%) and Medicaid (5.5%) are both substantial contributorsspending is expected to have the fastest growth (7.3% per year for 2021-2030) primarily due to the rate of national health expenditure growth for the projection period. Both trends reflect the impact of an aging population, but in different ways. For Medicare, projected enrollment growth is a primary driver; for Medicaid, it is an increasing projected share of aged and disabled enrollees.growth.

Managed care health plans were developed in the U.S., primarily during the 1980s, in an attempt to mitigate the rising cost of providing health carehealthcare to populations covered by health insurance. These managed care health plans enroll members through their employers in connection with federal Medicare benefits or state Medicaid programs. As a result of the prevalence of these health plans, many seniors now becoming eligible for Medicare have been interacting with managed care companies through their employers for the last 30 years. Individuals now turning 65 are likely more familiar with the managed care setting than previous Medicare populations. The healthcare industry, however, is highly regulated by various government agencies and heavily relies on reimbursement and payments from government sponsoredgovernment-sponsored programs such as Medicare and Medicaid. Companies in the healthcare industry therefore have to organize, and operate around, and face challenges from idiosyncratic laws and regulations.

Many health plans recognize both the opportunity for growth from adding members, as well as the potential risks and costs associated with managing additional members. In California, many health plans subcontract a significant portion of the responsibility for managing patient care to integrated medical systems such as usApolloMed and our affiliated physician groups. These integrated health carehealthcare systems offer a comprehensive medical delivery system, and sophisticated care management know-how, and infrastructure to more efficiently provide for the health carehealthcare needs of the population enrolled with that health plan. While reimbursement models for these arrangements vary around the U.S., health plans often prospectively pay the integrated health carehealthcare system a fixed capitation payment, which is oftenfrequently based on a percentage of the amount received by the health plan. Capitation payments to integrated health carehealthcare systems, in the aggregate, represent a prospective budget from which the system manages care-related expenses on behalf of the population enrolled with that system. To the extent that these systems manage such expenses under the capitated levels, the system realizes an operating profit. On the other hand, if the expenses exceed projected levels, the system will realize an operating deficit. Since premiums paid represent a substantial amount per person, there is a significant revenue opportunity for an integrated medical system that is able to effectively manage health carehealthcare costs for the capitated arrangements entered into by its affiliated physician groups.

We believe that the healthcare industry is undergoing a significant transformation and the demand for our offerings is driven by the confluence of a number of fundamental healthcare industry trends, including:

Integrated medical systems that are able to pool a large number of patients, such as ourthe Company and ourits affiliated physician groups, are positioned to take advantage of industry trends, meet patient and government demands, and benefit from cost advantages resulting from their scale of operation and integrated approach of care delivery. In addition, integrated medical systems with years of managed care experience can leverage their expertise and sizeable medical data to identify specific treatment strategies and interventions, improve the quality of medical care and lower cost. Many integrated medical systems have also established physician performance metrics that allow them to monitor quality and service outcomes achieved by participating physicians in order to reward efficient, high qualityhigh-quality care delivered to members and initiate improvement efforts for physicians whose performance can be enhanced.

Ambulatory surgery centers and other outpatient clinics are healthcare facilities that specialize in performing outpatient surgeries, ambulatory treatments, and diagnostic and other services in local communities. As medical care has increasingly been delivered in clinic settings, many integrated medical systems also operate healthcare facilities primarily focused on the diagnosis and/or care of outpatients, including those with chronic conditions such as heart disease and diabetes, to cover the primary healthcare needs of local communities.

Hospitalists are doctors specialized in the care of patients in the hospital. Hospitalists assume the inpatient care responsibilities otherwise provided by primary care or other attending physicians and are reimbursed through the same billing procedures as other physicians. Hospitalists tend to focus exclusively on inpatient care. By practicing in the same facilities, hospitalists perform consistent functions, interact regularly with the same healthcare professionals, and thus are familiar with specific and unique hospital processes, which can result in greater efficiency, less process variability, and better outcomes. Through managing the treatment of a large number of patients with similar clinical needs, hospitalists generally develop practice expertise

Population health management (“PHM”) is a central trend within healthcare delivery, which includes the aggregation of patient data across multiple health information technology resources, the analysis of that data into a single, actionable patient record, and the actions through which care providers can improve both clinical and financial outcomes. PHM seeks to improve the health outcomes by monitoring and identifying individual patients, aggregating data, and providing a comprehensive clinical picture of each patient. Using that data, providers can track, and hopefully improve, clinical outcomes while lowering costs. A successful PHM platform requires a robust care and risk management infrastructure, a cohesive delivery system, and a well-managed partnership network.

Our Business Operations

Each of our affiliated IPAs is comprised ofcomprises a network of independent primary care physicians and specialists who collectively care for patients and contract with HMOs to provide physician services to their enrollees typically under capitated arrangements. Under the capitated model, aan HMO pays the IPA a capitation payment and assigns it the responsibility for providing physician services required by patients. The IPA physicians are exclusively in control of, and responsible for, all aspects of the practice of medicine for enrolled patients. Most of the HMO agreements have an initial term of two years renewing automatically for successive one-year terms. The HMO agreements generally allow either party to terminate the HMO agreements without cause typically with a four to six months advance notice and provide for a termination for cause by the HMO at any time.

Our MSOs generally provide services to our affiliated IPAs or ACOs under long-term MSAs, pursuant to which they manage certain non-medical services for the physician groups and have exclusive authority over all non-medical decision makingdecision-making related to ongoing business operations. These services include but are not limited to:

In February 2022, CMS announced that APAACO was approved to participate in the NGACOGPDC Model and APAACO began operations under this new model.model in 2022. Under the current Administration, changes were made to the model, and it was renamed the ACO Realizing Equity, Access, and Community Health Model. The ACO REACH Model commenced on January 1, 2023. We havehad devoted and expect to continue to devote, significant effort and resources, financial and otherwise, to the NGACO Model. APAACO isGPDC Model in PY2022, and have now transitioned to the ACO REACH Model in its fourth year of participation under itsPY2023. APAACO’s new Participation Agreement with CMS.for the ACO REACH Model runs through PY2026. The Company continues to be eligible to receive any shared savings or deficit under the GPDC Model for PY2022. The Company will be eligible to receive any shared savings or deficit under the ACO REACH Model for Performance Years 2023-2026.

In advance of its participation in the NGACOACO REACH Model, APAACO entered into agreements with over 750approximately 850 medical care providers, including physicians, hospitals, nursing facilities and multiple labs, radiology centers, outpatient surgery centers, dialysis clinics, and other service providers. APAACO negotiated discounted rates and such providers agreed to receive 100% of their claims for beneficiaries reimbursed by APAACO.

Under the Participation Agreement, APAACO must require its participantsParticipant and preferred providersPreferred Providers to make medically necessary covered services available to beneficiaries in accordance with applicable laws, regulations, and guidance,guidance. During each Performance Year, from PY2021 (April-December 2021) through PY2026 (Calendar Year 2026), ACOs and APAACOtheir Participant Providers may not simultaneously participate in the Medicare Shared Savings Program. The determination of whether such an overlap exists during PY2021 – PY2026 will be made at the TIN level. During the GPDC / ACO REACH Model’s performance years (PY2021 – PY2026), Participant Providers may not simultaneously participate in the GPDC / ACO REACH Model and its participantsanother model tested or expanded under section 1115A of the Act that involves shared savings, or any other Medicare initiative that involves shared savings unless otherwise permitted by CMS. For example, Participant Providers may not participate in any other Medicarethe Kidney Care Choices model or the Vermont All-Payer ACO Model. In addition, for the Primary Care First model, Independence at Home demonstration, and the Maryland Primary Care Program, which have similar payment structures to the GPDC / ACO REACH Model, overlap is prohibited even though they are not shared savings initiatives. For each of these initiatives, overlap is determined based on the TIN/NPI combination of the participating clinicians.

There are different levels of financial risk and reward that an ACO may select under the NGACOGPDC / ACO REACH Model, and the extent of risk and reward may be limited on a percentage basis. The NGACOGPDC / ACO REACH Model offers two risk arrangement options.options: the Professional risk track and the Global risk track.

Under the GPDC model, this discount was 2% of the benchmark. Under the ACO REACH model, this discount is 3% of the benchmark for PY2023-24, increasing to 3.5% for PY2025-26. APA ACO has opted for Risk Arrangement A and a shared savings and losses cap of 5%.the Global risk track.

APAACO opted for, and was approved by CMS effective on April 1, 2017 to participate in, TCC, under the AIPBPGlobal risk track, which is the most advanced risk-taking payment model. When approved, APAACO was the only ACO participatingmodel in the AIPBP track, out of 44 ACOs approved for the NGACO ModelGPDC / ACO REACH program. Under TCC in the U.S. Under the AIPBPGlobal risk track, CMS estimates the total annual expenditures for APAACO’s beneficiaries and then pays that projected amount to APAACO on a PBPM basis.

Throughout the GPDC and ACO REACH programs, a substantial portion of APAACO’s spending benchmark is held at-risk by CMS, subject to APAACO receiving approximately $9.3 million per month frommeeting certain quality measures as determined by CMS.

Our Revenue Streams

Our revenue reflected in the accompanying consolidated financial statements includes revenue generated by our subsidiaries and consolidated entities. Revenue generated by consolidated entities, however, does not necessarily result in available or distributable cash for ApolloMed. Some revenue is generated from Excluded Assets that remain solely for the benefit of APC and its shareholders. Our revenue streams flow from various multi-year renewable contractual arrangements that vary by type of business operation as follows:

Our capitation revenue consists primarily of capitated fees for medical services we provide under capitated arrangements made directly with various managed care providers, including HMOs. Capitation revenues arerevenue is typically prepaid monthly to us based on the number of enrollees selecting us as their healthcare provider. Capitation is a fixed payment amount per patient per unit of time paid in advance for the delivery of health carehealthcare services, whereby the service providers are generally liable for excess medical costs. The actual amount paid is determined by the ranges of services provided, the number of patients enrolled, and the

Per member per month (“PMPM”) managed care contracts generally have a term of one year or longer. All managed care contracts have a single performance obligation that constitutes a series for the provision of managed healthcare services for a population of enrolled members for the duration of the contract. The transaction price for PMPM contracts is variable, as it primarily includes PMPM fees associated with unspecified membership that fluctuates throughout the term of the contract. In certain contracts, PMPM fees also include adjustments for items such as performance incentives, performance guarantees, and risk shares.

Capitation arrangements are supplemented by risk sharingrisk-sharing arrangements. We have two different types of capitation risk sharingrisk-sharing arrangements: full riskfull-risk and shared riskshared-risk arrangements.

We enter into full riskfull-risk capitation arrangements with certain health plans and local hospitals, which are administered by a related party, where the hospital is responsible for providing, arranging, and paying for institutional risk. We are responsible for providing, arranging, and paying for professional risk. Under a full risk pool sharingfull-risk pool-sharing agreement, we generally receive a percentage of the net surplus from the affiliated hospital’s risk pools with HMOs after deductions for the affiliated hospital’s costs. Advance settlement payments are typically made quarterly in arrears if there is a surplus. Risk pool settlements under arrangements with health plans and hospitals are recognized using the most likely amount methodology and amounts are only included in revenue to the extent that it is probable that a significant reversal of cumulative revenue will not occur once any uncertainty is resolved. The assumptions for medical loss ratios (“MLR”), incurred but not reported (“IBNR”) completion factor and constraint percentages were used by management in applying the most likely amount methodology.

Under capitation arrangements with certain HMOs, we participate in one or more shared riskshared-risk arrangements relating to the provision of institutional services to enrollees (shared risk(shared-risk arrangements) and thus can earn additional revenue or incur losses based upon the enrollee utilization of institutional services. Shared riskShared-risk capitation arrangements are entered into with certain health plans, which are administered by the health plan, where we are responsible for rendering professional services, but the health plan does not enter into a capitation arrangement with a hospital and therefore, the health plan retains the institutional risk. Shared riskShared-risk deficits, if any, are not payable until and unless (and only to the extent of any) risk sharingrisk-sharing surpluses are generated. At the termination of the HMO contract, any accumulated deficit will be extinguished.

In addition to risk-sharing revenues, we also receive incentives under “pay-for-performance” programs for quality medical care, based on various criteria. As an incentive to control enrollee utilization and to promote quality care, certain HMOs have designed quality incentive programs and commercial generic pharmacy incentive programs to compensate us for our efforts to improve the quality of services and to promote the efficient and effective use of pharmacy supplemental benefits provided to HMO members. The incentive programs track specific performance measures and calculate payments to us based on the performance measures.

Generally, for the foregoing arrangements, the final settlement is dependent on each distinct day’s performance within the annual measurement period, but cannot be allocated to specific days until the full measurement period has occurred and performance can be assessed.

Management fee income encompasses fees paid for management, physician advisory, healthcare staffing, administrative, and other non-medical services provided by us to IPAs, hospitals, and other healthcare providers. Such fees may be in the form of billings at agreed-upon hourly rates, percentages of revenue, or fee collections, or amounts fixed on a monthly, quarterly, or annual basis. The revenue may include variable arrangements measuring factors such as hours staffed, patient visits, or collections per visit against benchmarks, and, in certain cases, may be subject to achieving quality metrics or fee collections.

Through APAACO, we participate in the Global Risk track with TCC in the GPDC / ACO REACH Model sponsored by CMS. Under the GPDC / ACO REACH Model, we recruit a group of Participant and Preferred (in-network) Providers. Based on the Participant Providers that join our ACO, CMS grants us a pool of Traditional Medicare patients (beneficiaries) to manage. Our beneficiaries will receive services from physicians and other medical service providers that are both in-network and out-of-network. Under TCC, CMS estimates an average of in-network monthly expenditures for APAACO’s aligned beneficiaries and pays that projected amount to us in monthly installments. We are then responsible for paying our in-network providers for all Part A and Part B expenditures incurred by our beneficiaries with those providers. In addition, we bear risk on all Part A and Part B expenditures (both in-network and out-of-network) based on a budgetary benchmark established with CMS. Claims from out-of-network providers are processed and paid by CMS. Our shared savings or losses in managing our beneficiaries are generally determined on an annual basis after reconciliation with CMS. Pursuant to our risk-share agreement with CMS, we will be eligible to receive the surplus (shared savings) or be liable for the deficit (shared losses) according to the budgetary benchmark established by CMS based on our efficiency or lack thereof, in managing the expenditures associated with beneficiaries aligned to us by CMS. We recognize such savings or deficit upon substantial completion of reconciliation and determination of the amounts. We also recognize the final budgetary benchmark established by CMS, net of discounts, and retrospective trend adjustments, as revenue. Our maximum shared savings or losses are determined by the risk track we elect with CMS. Under the Global Risk track, we are responsible for 100% of shared savings or losses up to 25% of the total budgetary benchmark established by CMS, with adjusted risk corridors taking effect for any proportion of shared savings / losses exceeding 25% of the benchmark—for savings/losses of 25-35% of the benchmark, we assume 50% risk responsibility,

Through APAACO, we participated in the AIPBP track of the NGACO Model sponsored by CMS. Under the NGACO Model, CMS grantsgranted us a pool of patients to manage (direct care and pay providers) based on a budgetary benchmark established

Our Key Payors

We have a few keyA limited number of payors that represent a significant portion of our net revenue. For the years ended December 31, 2019, 20182022, 2021 and 2017,2020, four payors accounted for an aggregate of 51.6%59.0%, 61.5%49.6%, and 54.6%53.4% of our total net revenue, respectively.

Our Strengths and Advantages

The following are some of the material opportunities that we believe exist for our company.company:

We believe our key strength lies in our combined clinical, administrative, and technology capabilities. While many companies separately provide clinical, MSO, or technology support services, to our knowledge there are currently very few organizations like us that provide all three types of services to over 980,000approximately 1.3 million patients as of December 31, 2019.2022.

Through our subsidiaries, consolidated affiliates, and invested entities, we have been able to reduce our business risk and increase revenue opportunities by diversifying our service offerings and expanding our ability to manage patient care across a horizontally integrated care network. Our revenue is spread across our operations. Additionally, with our ability to monitor and manage care within our wide network, we are an attractive business partner to health plans, hospitals, IPAs, and other medical groups seeking to provide better care at lower costs.

As of December 31, 2019,2022, our physician network consisted of over 7,000approximately 11,000 contracted physicians, including primary care physicians, specialist physicians, and hospitalists, through our affiliated physician groups and ACOs.

In addition to delivering premium health care,healthcare, we believe in the importance of providing services that are sensitive to the needs of local communities, including their cultural affinities. This value is shared by physicians within our affiliated IPAs and medical groups, and promotes patient comfort in communicating with care providers.

We have developed long-standing relationships with and have earned trust from multiple health plans, hospitals, IPAs, and other medical groups that have helped to generate recurring contractual revenue for us.

We offer comprehensive and effective healthcare management programs to patients. We have developed expertise in population health management and care coordination, and in proper medical coding, which results in improved Risk Adjustment Factor (“RAF”) scores and higher payments from health plans, and in improving quality metrics in both inpatient and outpatient settings and thus patient satisfaction and CMS scores. Using our own proprietary risk assessment scoring tool, we have also developed our own protocol for identifying high-risk patients.

Competition

The healthcare industry is highly competitive and fragmented. We compete for customers across all of our services with other health carehealthcare management companies, including MSOs and healthcare providers, such as local, regional, and national networks of physicians, medical groups, and hospitals, many of which are substantially larger than us and have significantly greater financial and other resources, including personnel, than we have.

Our affiliated IPAs compete with other IPAs, medical groups, and hospitals, many of which have greater financial, personnel, and other resources available to them. In the greater Los Angeles area, such competitors include Regal Medical Group and Lakeside Medical group,Group, which are part of Heritage Provider Network (“Heritage”), as well as Optum (f.k.a. HealthCare Partners, which was recently acquired byPartners), a subsidiary of UnitedHealth Group.

Our NGACO, APAACO competes with other sophisticated provider groups in the creation, administration, and management of ACOs, including MSSP ACOs and NGACOs, many of which have greater financial, personnel, and other resources available to them. In the greater Los Angeles area, majorMajor competitors of APAACO include Heritage California ACOPrivia Health and DaVita Medical ACO California.Aledade.

Our outpatient clinics compete with large ambulatory surgery centers and/or diagnostic centers such as Foothill Cardiology (California Heart Medical Group), RadNet and Envision Healthcare, many of which have greater financial, personnel, and other resources available to them, as well as smaller clinics that have ties to local communities. Optum (f.k.a. HealthCare PartnersPartners) also has its own urgent care centers, clinics, and diagnostic centers.

Because individual physicians may provide hospitalist services if they have necessary credentials and privileges, the markets for hospitalist services are highly fragmented. Our affiliated hospitalist groups face competition primarily from numerous small inpatient practices in existing and expanding markets, but also compete with large physician groups, many of which have greater financial, personnel, and other resources available to them. Some of such competitors operate on a national level, including EmCare, Team Health, and Sound Physicians.

Regulatory Matters

As a healthcare company, our operations and relationships with healthcare providers, such as hospitals, other healthcare facilities, and healthcare professionals, are subject to extensive and increasing regulation by numerous federal, state, and local government agencies, including the Office of Inspector General, (“OIG”), the Department of Justice, CMS, and various state authorities. These laws and regulations often are interpreted broadly and enforced aggressively. Imposition of liabilities associated with a violation of any of these healthcare laws and regulations could have a material adverse effect on our business, financial condition, or results of operations. We cannot guarantee that our practices will not be subject to government scrutiny or be found to violate certain healthcare laws. Government investigations and prosecutions, even if we are ultimately found to be without fault, can be costly and disruptive to our business. Moreover, changes in healthcare legislation or government regulation may restrict our existing operations, limit our expansion, or impose additional compliance requirements and costs, any of which could have a material adverse effect on our business, financial condition, or results of operations. Below are brief descriptions of some, but not all, of such laws and regulations that affect our business operations.

Our consolidated financial statements include our subsidiaries and VIEs. Some states have laws that prohibit business entities with non-physician owners, such as ApolloMed and its subsidiaries, from practicing medicine, employing physicians to practice medicine, or exercising control over medical decisions by physicians; whichphysicians. These laws are generally referred to as corporate practice of medicine laws. States that have corporate practice of medicine laws requirepermit only physicians to practice medicine, exercise control over medical decisions, or engage in certain arrangements, such as fee-splitting, with physicians. In these states, a violation of the corporate practice of medicine prohibition constitutes the unlawful practice of medicine, which is a public offense punishable by fines and other criminal penalties. In addition, any physician who participates in a scheme that violates the state’s corporate practice of medicine prohibition may be punished for aiding and abetting a lay entity in the unlawful practice of medicine.

California is a corporate practice of medicine state, and we operate by maintaining long-term MSAs with our affiliated IPAs and medical groups, each of which is owned and operated by physicians only, and employs or contracts with additional physicians to provide medical services. Under such MSAs, our wholly owned MSOs are contracted to provide non-medical management and administrative services, such as financial and risk management, as well as information systems, marketing, and administrative support to the IPAs and medical groups. The MSAs typically have an initial term of 3-301-10 years and are generally not terminable by our affiliated IPAs and medical groups except in the case of bankruptcy, gross negligence, fraud, or other illegal acts by the contracting MSO.

Through the MSAs and the relationship with the physician owners of our medical affiliates, we have exclusive authority over all non-medical decisions related to the ongoing business operations of those affiliates. Consequently, ApolloMed consolidates the revenue and expenses of such affiliates as their primary beneficiary from the date of execution of the applicable MSA. When necessary, our Co-Chief Executive Officers, Dr. Kenneth Sim andOfficer, Dr. Thomas Lam, serveserves as nominee shareholders,shareholder of affiliated

Under these arrangements, our MSOs perform only non-medical functions, do not represent to offer medical services, and do not exercise influence or control over the practice of medicine by physicians. The California Medical Board, as well as other state’sstates’ regulatory bodies, has taken the position that MSAs that confer too much control over a physician practice to MSOs may violate the prohibition against corporate practice of medicine. Some of the relevant laws, regulations, and agency interpretations in California and other states that have corporate practice prohibitions have been subject to limited judicial and regulatory interpretation. Moreover, state laws and regulatory interpretations are subject to change and regulatory authorities.change. Other parties, including our affiliated physicians, may assert that, despite these arrangements, ApolloMed and its subsidiaries are engaged in the prohibited corporate practice of medicine or that such arrangements constitute unlawful fee-splitting between physicians and non-physicians. If this occurred, we could be subject to civil or criminal penalties, our MSAs could be found legally invalid and unenforceable in whole or in part, and we could be required to restructure arrangements with our affiliated IPAs and medical groups. If we were required to change our operating structures due to determination that a corporate practice of medicine violation existed, such a restructuring might require revising our MSOs’ management fees.

The False Claims Act, 31 U.S.C. §§ 3729 - 3733, imposes civil liability on individuals or entities that submit false or fraudulent claims for payment to the federal government. The False Claims Act provides, in part, that the federal government may bring a lawsuit against any person whom it believes has knowingly or recklessly presented, or caused to be presented, a false or fraudulent request for payment from the federal government, or who has made a false statement or used a false record to get a claim for payment approved. Private parties may initiate qui tam whistleblower lawsuits against any person or entity under the False Claims Act in the name of the federal government and may share in the proceeds of a successful suit. The federal government has used the False Claims Act to prosecute a wide variety of alleged false claims and fraud allegedly perpetrated against Medicare and state healthcare programs. By way of illustration, these prosecutions may be based upon alleged coding errors, billing for services not rendered, billing services at a higher payment rate than appropriate, and billing for care that is not considered medically necessary. The federal government and a number of courts have taken the position that claims presented in violation of certain other statutes, including the federal Anti-Kickback Statute or the Stark Law, can also be considered a violation of the False Claims Act based on the theory that a provider impliedly certifies compliance with all applicable laws, regulations, and other rules when submitting claims for reimbursement.

Penalties for False Claims Act violations include substantial fines ranging from $5,500 to $11,000 for each false claim, plus up to three times the amount of damages sustained by the government. A False Claims Act violation may provide the basis for the imposition of administrative penalties as well as exclusion from participation in governmental healthcare programs, including Medicare and Medicaid. In addition to the provisions of the False Claims Act, which provide for civil enforcement, the federal government also can use several criminal statutes to prosecute persons who are alleged to have submitted false or fraudulent claims to the government for payments.

A number of states including California have enacted laws that are similar to the federal False Claims Act. Under Section 6031 of the Deficit Reduction Act of 2005 (“DRA”), as amended, if a state enacts a false claims act that is at least as stringent as the federal statute and that also meets certain other requirements, the state will be eligible to receive a greater share of any monetary recovery obtained pursuant to certain actions brought under the state’s false claims act. As a result, more states are expected to enact laws that are similar to the federal False Claims Act in the future along with a corresponding increase in state false claims enforcement efforts. In addition, sectionSection 6032 of the DRA requires entities that make or receive annual Medicaid payments of $5.0 million or more from any one state to provide their employees, contractors, and agents with written policies and employee handbook materials on federal and state False Claims Acts and related statues.

The federal Anti-Kickback Statute is a provision of the Social Security Act of 1972 that prohibits as a felony offense the knowing and willful offer, payment, solicitation or receipt of any form of remuneration in return for, or to induce, (1) the referral of a patient for items or services for which payment may be made in whole or part under Medicare, Medicaid, or other federal healthcare programs, (2) the furnishing or arranging for the furnishing of items or services reimbursable under Medicare, Medicaid, or other federal healthcare programs or (3) the purchase, lease, or order or arranging or recommending the purchasing, leasing, or ordering of any item or service reimbursable under Medicare, Medicaid, or other federal healthcare programs. The Patient Protection and Affordable Care Act (“ACA”) amended section 1128B of the Social Security Act to make it clear that a person need not have actual knowledge of the statute, or specific intent to violate the statute, as a predicate for a violation. The OIG, which has the authority to impose administrative sanctions for violation of the statute, has adopted as its standard for review a judicial interpretation,

Due to the breadth of the Anti-Kickback Statute’s broad prohibitions, statutory exceptions exist that protect certain arrangements from prosecution. In addition, the OIG has published safe harbor regulations that specify arrangements that are deemed protected from prosecution under the Anti-Kickback Statute, provided all applicable criteria are met. The failure of an activity to meet all of the applicable safe harbor criteria does not necessarily mean that the particular arrangement violates the Anti-Kickback Statute, but these arrangements may be subject to scrutiny and prosecution by enforcement agencies. We may be less willing than some competitors to take actions or enter into arrangements that do not clearly satisfy the OIG safe harbors and suffer a competitive disadvantage.

Some states have enacted statutes and regulations similar to the Anti-Kickback Statute, but which may be applicable regardless of the payor source for the patient. These state laws may contain exceptions and safe harbors that are different from and/or more limited than those of the federal law and that may vary from state to state. For example, California has adopted the Physician Ownership and Referral Act of 1993 (“PORA”). PORA makes it unlawful for physicians, surgeons, and other licensed professionals to refer a person for certain health carehealthcare services if they have a financial interest with the person or entity that receives the referral. While PORA also provides certain exemptions from this prohibition, failure to fit within an exemption in violation of PORA can lead to a misdemeanor offense that may subject a physician to civil penalties and disciplinary action by the Medical Board of California.
    

We cannot assure that the applicable regulatory authorities will not determine that some of our arrangements with physicians violate the federal Anti-Kickback Statute or other applicable laws. An adverse determination could subject us to different liabilities, including criminal penalties, civil monetary penalties, and exclusion from participation in Medicare, Medicaid, or other health carehealthcare programs, any of which could have a material adverse effect on our business, financial condition, or results of operations.

The federal Stark Law, 42 U.S.C. 1395nn, also known as the physician self-referral law, generally prohibits a physician from referring Medicare and Medicaid patients to an entity (including hospitals) providing ‘‘designated“designated health services,’’” if the physician or a member of the physician’s immediate family has a ‘‘financial relationship’’“financial relationship” with the entity, unless a specific exception applies. Designated health services include, among other services, inpatient hospital services, outpatient prescription drug services, clinical laboratory services, certain imaging services (e.g., MRI, CT, ultrasound), and other services that our affiliated physicians may order for their patients. The prohibition applies regardless of the reasons for the financial relationship and the referral;referral, and therefore, unlike the federal Anti-Kickback Statute, intent to violate the law is not required. Like the Anti-Kickback Statute, the Stark Law contains statutory and regulatory exceptions intended to protect certain types of transactions and arrangements. Unlike safe harbors under the Anti-Kickback Statute with which compliance is voluntary, an arrangement must comply with every requirement of a Stark Law exception or the arrangement is in violation of the Stark Law.

Because the Stark Law and implementing regulations continue to evolve and are detailed and complex, while we attempt to structure its relationships to meet an exception to the Stark Law, there can be no assurance that the arrangements entered into by us with affiliated physicians and facilities will be found to be in compliance with the Stark Law, as it ultimately may be implemented or interpreted. The penalties for violating the Stark Law can include the denial of payment for services ordered in violation of the statute, mandatory refunds of any sums paid for such services, and civil penalties of up to $15,000 for each violation, double damages, and possible exclusion from future participation in the governmental healthcare programs. A person who engages in a scheme to circumvent the Stark Law’s prohibitions may be fined up to $100,000face substantial fines for each applicable arrangement or scheme.

Some states have enacted statutes and regulations against self-referral arrangements similar to the federal Stark Law, but which may be applicable to the referral of patients regardless of their payor source and which may apply to different types of services. These state laws may contain statutory and regulatory exceptions that are different from those of the federal law and that may vary from state to state. For example, California has adopted the Physician Ownership and Referral Act of 1993 (“PORA”). PORA makes it unlawful for physicians, surgeons, and other licensed professionals to refer a person for certain healthcare services if they have a financial interest with the person or entity that receives the referral. While PORA also provides certain exemptions from this prohibition, failure to fit within an exemption in violation of PORA can lead to a misdemeanor offense that may subject a physician to civil penalties and disciplinary action by the Medical Board of California.

An adverse determination under these state laws and/or the federal Stark Law could subject us to different liabilities, including criminal penalties, civil monetary penalties, and exclusion from participation in Medicare, Medicaid, or other health carehealthcare programs, any of which could have a material adverse effect on our business, financial condition, or results of operations.

The privacy regulations promulgated under the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), as amended, contain detailed requirements concerning the use and disclosure of individually identifiable patient health information (“PHI”) by entities like our MSOs and affiliated IPAs and medical groups. HIPAA covered entities must implement certain administrative, physical, and technical security standards to protect the integrity, confidentiality, and availability of certain electronic health information received, maintained, or transmitted. HIPAA also implemented standard transaction code sets and standard identifiers that covered entities must use when submitting or receiving certain electronic healthcare transactions, including billing and claim collection activities. New health information standards could have a significant effect on the manner in which we do business, and the cost of complying with new standards could be significant.

Violations of the HIPAA privacy and security rules may result in civil and criminal penalties, including a tiered system of civil money penalties that range from $100 to $50,000 per violation, with a cap of $1.5 million per year for identical violations.penalties. A HIPAA coveredHIPAA-covered entity must also promptly notify affected individuals where a breach affects more than 500 individuals and report annually any breaches affecting fewer than 500 individuals.

State attorneys general may bring civil actions on behalf of state residents for violations of the HIPAA privacy and security rules, obtain damages on behalf of state residents, and enjoin further violations. Many states also have laws that protect the privacy and security of confidential, personal information, which may be similar to or even more stringent than HIPAA. Where state laws are more protective than HIPAA, we have to comply with the stricter provisions. Some of these state laws may impose fines and penalties on violators and may afford private rights of action to individuals who believe their personal information has been misused. California’s patient privacy laws, for example, provide for monetary penalties and permit injured parties to sue for damages. Both state and federal laws are subject to modification or enhancement of privacy protection at any time.

If we fail to comply with HIPAA or similar state laws, we could incur substantial civil monetary or criminal penalties. We expect increased federal and state privacy and security enforcement efforts.

The Knox-Keene Health Care Service Plan Act of 1975 (Health and Safety Code Section 1340, et seq.), as amended (the “Knox-Keene Act”), is the California law that regulates managed care plans. Neither our MSOs nor their managed medical groups and IPAs hold a Knox-Keene license. Some of the medical groups and IPAs that have entered into MSAs with our MSOs have historically contracted with health plans and other payors to receive capitation payments and assumed the financial responsibility for professional services. In many of these cases, the health plans or other payors separately enter into contracts with hospitals that receive payments and assume some type of contractual financial responsibility for their institutional services. In some instances, our affiliated medical groups and IPAs have been paid by their contracting payorpayors or hospitals for the financial outcome of managing the care costs associated with both the professional and institutional services received by patients, and have recognized a percentage of the surplus of institutional revenues less institutional expense as the medical groups’ and IPAs’ net revenuesrevenues; and, has beenunder certain circumstances, may be responsible for a percentage of any short-fallshortfall in the event that institutional expenses exceed institutional revenues. While our MSOs and their managed medical groups and IPAs are not contractually obligated to pay claims to hospitals or other institutions under these arrangements, if it is determined that our MSOs or the medical groups and IPAs have been inappropriately taking financial risk for institutional and professional services without Knox-Keene licenseslicense or regulatory exemption as a result of their hospital and physician arrangements, we may be required to obtain limiteda restricted Knox-Keene licenseslicense to resolve such violations and we could be subject to civil and criminal liability, any of which could have a material adverse effect on our business, financial condition, or results of operations.

In addition, some states require ACOs to be registered or otherwise comply with state insurance laws. Our ACOs do not currently take financial risk, and are therefore not registered with any state insurance agency. If it is determined that we have been inappropriately operating an ACO without state registration or licensure, we may be required to obtain such registration or licensure to resolve such violations and we could be subject to liability, which could have a material adverse effect on our business, financial condition, or results of operations.

We are subject to federal, state, and local regulations governing the storage, use, and disposal of waste materials and products. Although we believe that our safety procedures for storing, handling, and disposing of these materials and products comply with the standards prescribed by law and regulation, we cannot eliminate the risk of accidental contamination or injury from those hazardous materials. In the event of an accident, we could be held liable for any damages that result and any liability could exceed the limits or fall outside the coverage of our insurance policies, which we may not be able to maintain on acceptable terms, or at all. We could incur significant costs and the attention of our management could be diverted to comply with current or future environmental laws and regulations. Federal regulations promulgated by the Occupational Safety and Health Administration impose additional requirements on us, including those protecting employees from exposure to elements such as blood-borne pathogens. We cannot predict the frequency of compliance, monitoring, or enforcement actions to which we may be subject as those regulations are being implemented, which could adversely affect our operations.

We are also subject to other federal and state healthcare laws that could have a material adverse effect on our business, financial condition, or results of operations. The Health Care Fraud Statute prohibits any person from knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, which can be either a government or private payor plan. Violation of this statute, even in the absence of actual knowledge of or specific intent to violate the statute, may be charged as a felony offense and may result in fines, imprisonment, or both. The Health Care False Statement Statute prohibits, in any matter involving a federal health carehealthcare program, anyone from knowingly and willfully falsifying, concealing, or covering up, by any trick, scheme, or device, a material fact, or making any materially false, fictitious, or fraudulent statement or representation, or making or using any materially false writing or document knowing that it contains a materially false or fraudulent statement. A violation of this statute may be charged as a felony offense and may result in fines, imprisonment, or both. Under the Civil Monetary Penalties Law of the Social Security Act, a person (including an organization) is prohibited from knowingly presenting or causing to be presented to any United States officer, employee, agent, or department, or any state agency, a claim for payment for medical or other items or services where the person knows or should know (a) the items or services were not provided as described in the coding of the claim, (b) the claim is a false or fraudulent claim, (c) the claim is for a service furnished by an unlicensed physician, (d) the claim is for medical or other items or service furnished by a person or an entity that is in a period of exclusion from the program, or (e) the items or services are medically unnecessary items or services. Violations of the law may result in substantial penalties, of up to $10,000 per claim, treble damages, and exclusion from federal healthcare programs. In addition, the OIG may impose civil monetary penalties against any physician who knowingly accepts payment from a hospital (as well as against the hospital making the payment) as an inducement to reduce or limit medically necessary services provided to Medicare or Medicaid program beneficiaries. Further, except as permitted under the Civil Monetary Penalties Law, a person who offers or transfers to a Medicare or Medicaid beneficiary any remuneration that the person knows or should know is likely to influence the beneficiary’s selection of a particular provider of Medicare or Medicaid payable items or services may be liable for civil money penalties of up to $10,000 for each wrongful act.

In addition to the state laws previously described, we may also be subject to other state fraud and abuse statutes and regulations if we expand our operations beyond California. Many states have adopted a form of anti-kickback law, self-referral prohibition, and false claims and insurance fraud prohibition. The scope and interpretations of these laws and the interpretations of them vary from state to state and are enforced by state courts and regulatory authorities, each with broad discretion. Generally, state laws reach to all healthcare services and not just those covered under a governmental healthcare program. A determination of liability under any of these laws could result in fines, and penalties, and restrictions on our ability to operate in these states. We cannot assure that our arrangements or business practices will not be subject to government scrutiny or be found to violate applicable fraud and abuse laws.

Licensure, Certification, Accreditation, and Related Laws and Guidelines

Our clinical personnel are subject to numerous federal, state, and local licensing laws and regulations, relating to, among other things, professional credentialing and professional ethics. Clinical professionals are also subject to state and federal regulation regarding prescribing medication and controlled substances. Our affiliated physicians and hospitalists must satisfy and maintain their individual professional licensing in each state where they practice medicine, including California, and many states require that nurse practitioners and physician assistants work in collaboration with or under the supervision of a physician. Each state defines the scope of practice of clinical professionals through legislation and through the respective Boards of Medicine and Nursing. Activities that qualify as professional misconduct under state law may subject our clinical personnel to sanctions, or to even lose their license and could, possibly, subject us to sanctions as well. Some state boards of medicine impose reciprocal discipline, that is, if a physician is disciplined for having committed professional misconduct in one state where he or she isthey are licensed, another state where he or she isthey are also licensed may impose the same discipline even though the conduct occurred in another state. Since we and our affiliated medical groups perform services at hospitals and other healthcare facilities, we may indirectly be subject to laws, ethical guidelines, and operating standards of professional trade associations and private accreditation commissions (such as the American Medical Association and The Joint Commission) applicable to those entities. Penalties for non-compliance with these laws and standards include loss of professional license, civil or criminal fines and penalties, loss of hospital admitting privileges, and exclusion from participation in various governmental and other third-party healthcare programs. In addition, our affiliated facilities are subject to state and local licensing regulations ranging from the adequacy of medical care to compliance with building codes and environmental protection laws. Our ability to operate profitably will depend, in part, upon our ability, and the ability of our affiliated physicians and facilities, to obtain and maintain all necessary licenses and other approvals and operate in compliance with applicable health carehealthcare and other laws and regulations that evolve rapidly. We provide home health, hospice, and palliative care, which require compliance with additional regulatory requirements. Reimbursement for palliative care and house call services is generally conditioned on clinical professionals providing the correct procedure and diagnosis codes and properly documenting both the service and the medical necessity for the service. Incorrect or incomplete documentation and billing information, or the incorrect selection of codes for the level and type of service provided, could result in non-payment for services rendered or lead to allegations of billing fraud. We must also comply with laws relating to hospice care eligibility, development, and maintenance of care plans and coordination with nursing homes or assisted living facilities where patients live.

Professional Liability and Other Insurance Coverage

Our business has an inherent and significant risk of claims of medical malpractice against us and our affiliated physicians. We and our affiliated physician groups pay premiums for third-party professional liability insurance that provides indemnification on a claims-made basis for losses incurred related to medical malpractice litigation in order to carry out our operations. Our physicians are required to carry first dollar coverage with limits of liability equal to not less than $1.0 million for claims based on occurrence up to an aggregate of $3.0 million per year. Our IPAs purchase stop-loss insurance, which will reimburse them for claims from service providers on a per enrollee basis. The specific retention amount per enrollee per policy period is $60,000$45,000 to $75,000$100,000 for professional coverage. We also maintain worker’sworkers’ compensation, director and officer, and other third-party insurance coverage subject to deductibles and other restrictions that we believe are in accordance with industry standards. While we believe that our insurance coverage is adequate based upon claims experience and the nature and risks of our business, we cannot be certain that our insurance coverage will be adequate to cover liabilities arising out of pending or future claims asserted against us or our affiliated physician groups in the future where the outcomes of such claims are unfavorable. The ultimate resolution of pending and future claims in excess of our insurance coverage may have a material adverse effect on our business, financial position, results of operations, or cash flows.

We believe we enjoyare committed to supporting the professional development of our employees, providing competitive compensation and benefits and a good working relationshipsafe and inclusive workplace. We measure employee engagement on an ongoing basis to create a more innovative, productive, and profitable company. The results from engagement surveys are used to implement programs and processes designed to support employee retention and satisfaction. The Company believes a diverse workforce fosters innovation and cultivates an environment filled with our staff.unique perspectives and growth. Respect for human rights is fundamental to the Company’s business and its commitment to ethical business conduct.

We maintain a website at www.apollomed.net and make available there, free of charge, our periodic reports filed with the Securities and Exchange Commission (SEC),SEC, as soon as is reasonably practicable after filing. The SEC maintains a website at http://www.sec.gov that contains reports, proxy and information statements, and other information regarding issuers such as us that file electronically with the SEC.

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below, together with all of the other information in this Annual Report on Form 10-K, including the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part II, Item 7, and our consolidated financial statements and related notes, before making a decision to invest in our common stock. The risks and uncertainties described below may not be the only ones we face. If any of the risks actually occur, our business, financial condition, operating results, and prospects could be materially and adversely affected.

Risks Relating to Our General Business and Operations.

The    In 2019, the Company, AP-AMH, and APC recently consummated a series of interrelated transactions that may expose the Company and its subsidiaries and VIEs to additional risks, including the inability to repay a significant loan made in connection with such transactions.

The APC Transactions may expose the Company, its subsidiaries and its VIEs to additional risks, including without limitation, the following: AP-AMH may never be able to repay the AP-AMH Loan; even if AP-AMH does not, or cannot repay the loan, the Company will be obligated to pay principal and interest on the $290.0 millionAmended Credit Facility; in connection with the Credit Facility, the lenders were granted a first priority perfected security interest over all of the assets of the Company and its subsidiaries, and such lenders have the right to foreclose on those assets if the Company defaults on its obligations under the Amended Credit Facility; a disconnect could arise between APC achieving net income, declaring and paying dividends to AP-AMH, and AP-AMH making its required payments to the Company, which disconnect could materially impact the Company'sCompany’s financial results and its ability to make its required payments under the Amended Credit Facility; APC may be prohibited from paying, or may be unable to pay the dividends on its Series A Preferred Stock, including under the California Corporations Code; regulators could determine that the current, post-APC Transactions consolidated structure amounts to the Company violating California’s corporate practice of medicine doctrine; and the Company may be deemed an investment company, which could impose burdensome compliance requirements on the Company and restrict its future activities.

Section 404 of the Sarbanes-Oxley Act of 2002 requires us to evaluate the effectiveness of our internal controls over financial reporting as of the end of each fiscal year, and to include a management report assessing the effectiveness of our internal controls over financial reporting in our annual reportAnnual Report on Form 10-K for that fiscal year. Section 404 also requires our independent registered public accounting firm to attest to, and report on, management’s assessment of our internal controls over financial reporting. Our management, including our principal executive officer and principal financial officer, does not expect that our internal controls over financial reporting will prevent all errors and all fraud. A control system, no matter how well designedwell-designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud involving a company have been, or will be, detected. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and we cannot assure you that any design will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become ineffective because of changes in conditions or deterioration in the degree of compliance with policies or procedures. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. We cannot assure you that we or our independent registered public accounting firm will not identify a material weakness in our internal controls in the future. A material weakness in our internal controls over financial reporting would require management and our independent registered public accounting firm to consider our internal controls as ineffective. If our internal controls over financial reporting are not considered effective, we may experience a loss of public confidence, which could have an adverse effect on our business and on the market price of our common stock.

We may in the future require additional capital to grow our business and may have to raise additional funds by selling equity, issuing debt, borrowing, refinancing our existing debt, or selling assets or subsidiaries. These alternatives may not be available on acceptable terms to us or in amounts sufficient to meet our needs. The failure to obtain any required future financing may require us to reduce or curtail certain existing operations.

If a corporation undergoes an “ownership change” within the meaning of Section 382 of the Internal Revenue Code of 1986, as amended, its net operating loss carryforwards and certain other tax attributes arising from before the ownership change are subject to limitations on use after the ownership change. In general, an ownership change occurs if there is a cumulative change in the corporation’s equity ownership by certain stockholders that exceeds 50 percentage points over a rolling three-year period. Similar rules may apply under state tax laws. The Merger likely resulted in an ownership change for us and, accordingly, our net operating loss carryforwards and certain other tax attributes will be subject to use limitations after the Merger. Additional ownership changes in the future could result in additional limitations on our net operating loss carryforwards. Consequently, we may not be able to utilize a material portion of our net operating loss carryforwards and other tax attributes, to offset our tax liabilities, which could have a material adverse effect on our cash flows and results of operations.

A downturn in economic conditions could have a material adverse effect on our results of operations, financial condition, business prospects, and stock price. Historically, government budget limitations have resulted in reduced spending. Given that Medicaid is a significant component of state budgets, an economic downturn would put continued cost containment pressures on Medicaid outlays for healthcare services in California. The existing federal deficit and continued deficit spending by the federal government can lead to reduced government expenditures, including for government-funded programs in which we participate such as Medicare. An economic downturn and sustained unemployment may also impact the number of enrollees in managed care programs and the profitability of managed care companies, which could result in reduced reimbursement rates. Although we attempt to stay informed, any sustained failure to identify and respond to these trends could have a material adverse effect on our results of operations, financial condition, business, and prospects.

Throughout the pandemic, COVID-19 impacted certain aspects of our business as community self-isolation practices and shelter-in-place requirements reduced our inpatient visits. Continued shelter-in-place, quarantine, executive order, or related measures to combat the spread of COVID-19, as well as the perceived need by a nationalindividuals to continue such practices to avoid infection, among other factors, have impacted and are expected to continue to impact certain aspects of our results of operations, business, and financial condition. These measures and practices resulted in temporary closures of outpatient clinics, and may result in delays in entry into new markets and expansion in existing markets. Governmental authorities in California began reopening and lifting or localized outbreakrelaxing shelter-in-place and quarantine measures only to revert back to such restrictions in the face of a highly contagious disease or other public health crisis,increases in new COVID-19 cases. In addition, due to the shelter-in-place orders across the country, we have implemented work-from-home policies for many employees, which may impact productivity and a pandemic outsidedisrupt our business operations.

Healthcare organizations around the world, including our medical offices, have faced, and will continue to face, substantial challenges in treating patients with COVID-19, such as the diversion of hospital staff and resources from ordinary functions to the treatment of COVID-19, supply, resource, and capital shortages, and overburdening of staff and resource capacity. In the United States, governmental authorities have also recommended, and in certain cases required, that elective, specialty, and other procedures and appointments, including certain primary care services, be suspended or canceled to avoid non-essential patient exposure to medical environments and potential infection with COVID-19, and to focus limited resources and personnel capacity toward the treatment of COVID-19. Some of these measures and challenges will likely continue for the duration of the pandemic, which is uncertain, and will harm the results of operations, liquidity, and financial condition of these healthcare organizations, including certain of our health network partners. We cannot accurately predict at this time the ultimate severity or duration that the foregoing measures and challenges may have on these healthcare organizations, including us and our health network partners.

The COVID-19 pandemic and similar crises could also adversely impactdiminish the public’s trust in healthcare facilities, especially facilities that fail to accurately or timely diagnose, or are treating (or have treated) patients affected by infectious diseases. As certain of our business.

The global outbreak of COVID-19 continues to rapidly evolve. The ultimate impact of the COVID-19 pandemic or a similar health crisis nationally orepidemic is highly uncertain and subject to change. We cannot at this time precisely predict what effects the markets where we operate could adversely affectCOVID-19 outbreak will have on certain aspects of our business, results of operations, and financial results.  For example,condition, including due to uncertainties relating to the recent outbreakseverity of the 2019 Novel Coronavirus (COVID-19), which has been declared a globaldisease, the duration of the pandemic, has caused governments and the private sectorgovernmental responses to take a number of drastic measures to contain the spread of the coronavirus, including the suspension of classes at various colleges and universities, the cancellation of public events and other nonessential mass gatherings and the implementation of workplace telecommuting policies.  Such measures may have a substantial impact on employee attendance or productivity, which in turn may adversely affect our operations, including our ability to effectively provide MSO services to our affiliated IPAs and contracted physician groups in compliance with regulatory requirements.  An extended outbreak may also result in disruptions to critical infrastructures and our supply chains and the supply chains of our affiliated IPAs and contracted physician groups, including the supply of pharmaceuticals and medical supplies.  The duration and extent of the impact from the coronavirus outbreak depends on future developments that cannot be accurately predicted at this time, such as the severity and transmission rate of the virus, the extent and effectiveness of containment actions. If we are not able to respond to and manage the impact of such events effectively, our business could be harmed.pandemic.

There can be no assurances that all material issues that may be present in our operations, including from prior to the 2017 Merger, have been uncovered, or that factors outside of our control will not later arise. As a result, we may be forced to write-down or write-off assets, restructure operations, or incur impairment or other charges that could result in losses. Unexpected risks may arise and previously known risks may materialize in a manner not consistent with each company’s preliminary risk analysis. Even though these charges may not have an immediate impact on our liquidity, the fact that we report charges of this nature could contribute to negative market perceptions about us or our securities and may make our future financing difficult to obtain on favorable terms or at all.

From time to time, our intangible assets are subject to impairment testing. Under current accounting standards, our goodwill, including acquired goodwill, is tested for impairment on an annual basis and may be subject to impairment losses as circumstances change (e.g., after an acquisition). If we record an impairment loss, it could have a material adverse effect on our results of operations for the year in which the impairment is recorded. 

Our operations and performance depend primarily on California and U.S. economic conditions and their impact on purchases of, or capitated rates for, our healthcare services, and our business is significantly exposed to risks associated with government spending and private payor reimbursement rates. As a result of inflation and the global financial crisis that began in 2008,current impact on the market and the COVID-19-related 2020 recession, general economic conditions deteriorated significantly. Although the markets have improved significantly, the overall economic recovery since that time has been uneven. Declines in consumer and business confidence, as well as private and government spending, together with significant reductions in the availability and increases in the cost of credit and volatility in the capital and credit markets, have adversely affected the business and economic environment in which we operate and our profitability. Market disruption, increases in interest rates, and/or sluggish economic growth in any future period could adversely affect our patients’ spending habits, private payors’ access to capital, and governmental budgetary processes, which, in turn, could result in reduced revenue for us. The continuation or recurrence of any of these conditions may adversely affect our cash flows, results of operations, and financial condition. As economic uncertainty may continue in future periods, our patients, private payors, and government payors may alter their purchasing activities of healthcare services. Our patients may scale back healthcare spending, and private and government payors may reduce reimbursement rates, which may also cause delay or cancellation of consumer spending for discretionary and non-reimbursed healthcare. This uncertainty may also affect our ability to prepare accurate financial forecasts or meet specific forecasted results, and we may be unable to adequately respond to or forecast further changes in demand for healthcare services. Volatility and disruption of capital and credit markets may adversely affect our access to capital and increase our cost of capital. Should current economic and market conditions deteriorate, our ability to finance ongoing operations and our expansion may be adversely affected, we may be unable to raise necessary funds, our cost of debt or equity capital may increase significantly, and future access to capital markets may be adversely affected.

In our case, the VIE consolidation model applies to our controlled, but not owned, physician affiliatedphysician-affiliated entities. Our determination regarding the consolidation of our affiliates, however, could be challenged, which could have a material adverse effect on our operations. In addition, in the event of a change in accounting rules or FASB’s interpretations thereof, or if there were an adverse determination by a regulatory agency or a court or a change in state or federal law relating to the ability to maintain present agreements or arrangements with our affiliated physician groups, we may not be permitted to continue to consolidate the revenues of our VIEs.

As a routine part of our business, we utilize information security and information technology systems and websites that allow for the secure storage and transmission of proprietary or private information regarding our patients, employees, vendors, and others, including individually identifiable health information. A security breach of our network, hosted service providers, or vendor systems, may expose us to a risk of loss or misuse of this information, litigation, and potential liability. Hackers and data thieves are increasingly sophisticated and operate large-scale and complex automated attacks, including on companies within the healthcare industry. Although we believe that we take appropriate measures to safeguard sensitive information within our possession, we may not have the resources or technical sophistication to anticipate or prevent rapidly-evolvingrapidly evolving types of cyber-attacks targeted at us, our patients, or others who have entrusted us with information. Actual or anticipated attacks may cause us to incur costs, including costs to deploy additional personnel and protection technologies, train employees, and engage third-party experts and consultants. We invest in industry standardindustry-standard security technology to protect personal information. Advances in computer capabilities, new technological discoveries, or other developments may result in the technology used by us to protect personal information or other data being breached or compromised. In addition, data and security breaches can also occur as a result of non-technical failures. To our knowledge, we have not experienced any material breach of our cybersecurity systems. If we or our third-party service providers systems fail to operate effectively or are damaged, destroyed, or shut down, or there are problems with transitioning to upgraded or replacement systems, or there are security breaches in these systems, any of the aforementioned could occur as a result of natural disasters, software or equipment failures, telecommunications failures, loss or theft of equipment, acts of terrorism, circumvention of security systems, or other cyber-attacks,cyberattacks, we could experience delays or decreases in service, and reduced efficiency of our operations. Additionally, any of these events could lead to violations of privacy laws, loss of customers, or loss, misappropriation or corruption of confidential information, trade secrets or data, which could expose us to potential litigation, regulatory actions, sanctions, or other statutory penalties, any or all of which could adversely affect our business, and cause it to incur significant losses and remediation costs.

We are increasingly dependent on technology systems to operate our business, reduce costs, and enhance customer service. These systems include complex software systems and hosted applications that are provided by third parties. Software systems need to be updated on a regular basis with patches, bug fixes, and other modifications. Hosted applications are subject to service availability and reliability of hosting environments. We also migrate from legacy systems to new systems from time to time. Maintaining existing software systems, implementing upgrades, and converting to new systems are costly and require personnel and other resources. The implementation of these systems upgrades, and conversions is a complex and time-consuming project involving substantial expenditures for implementation activities, consultants, system hardware and software, often requires transforming our current business and processes to conform to new systems, and therefore, may take longer, be more disruptive, and cost more than forecast and may not be successful. If the implementation is delayed or otherwise is not successful, it may hinder our business operations and negatively affect our financial condition and results of operations. There are many factors that may materially and adversely affect the schedule, cost, and execution of the implementation process, including, without limitation,

We operate several leased premises. There is no assurance that we will be able to continue to occupy such premises in the future. For example, we currently rent our corporate headquarters on a month-to-month basis. We could thus spend substantial resources to meet the current landlords’ demands or look for other premises. We may be unable to timely renew such leases or renew them on favorable terms, if at all. If any current lease is terminated or not renewed, we may be required to relocate our operations at substantial costs or incur increased rental expenses, which could adversely affect our business, financial condition, and results of operations.

We onlyprimarily operate in California. Any material changes with respect to consumer preferences, taxation, reimbursements, financial requirements, or other aspects of the healthcare delivery in California or the state’s economic conditions could have an adverse effect on our business, results of operations, and financial condition.

Although we expect to provide a broad and competitive range of services, there can be no assurance of acceptance of current services by the marketplace. Our ability to procure new contracts may be dependent upon the continuing results achieved at the current facilities, upon pricing and operational considerations, and the potential need for continuing improvement to our existing services. Moreover, the markets for our new services may not develop as expected nor can there be any assurance that we will be successful in marketing any such services.

Risks Relating to Our Growth Strategy and Business Model.

Our business strategy is to grow rapidly by building a network of medical groups and integrated physician networks and is significantly dependent on locating and acquiring, partnering or contracting with medical practices to provide health carehealthcare delivery services. We seek growth opportunities both organically and through acquisitions of or alliances with other medical service providers. As part of our growth strategy, we regularly review potential strategic opportunities. Identifying and establishing suitable strategic relationships are time-consuming and costly. There can be no assurance that we will be successful. We cannot guarantee that we will be successful in pursuing such strategic opportunities or assure the consequences of any strategic transactions. If we fail to evaluate and execute strategic transactions properly, we may not achieve anticipated benefits and may incur increased costs.

Our strategic transactions involve a number of risks and uncertainties, including that:including:

We may be required to make certain contingent payments in connection with strategic transactions from time to time. The fair value of such payments is re-evaluatedreevaluated periodically based on changes in our estimate of future operating results and changes in market discount rates. Any changes in our estimated fair value are recognized in our results of operations. The actual payments, however, may exceed our estimated fair value. Increases in actual contingent payments compared to the amounts recognized may have an adverse effect on our financial condition.

There can be no assurance that we will be able to effectively integrate strategic relationships into our business, which may negatively impact our business model, revenues, results of operations, and financial condition. In addition, strategic transactions are time-intensive, requiring significant commitment of our management’s focus. If our management spends too much time on assessing potential opportunities, completing strategic transactions, and integrating strategic relationships, our management may not have sufficient time to focus on our existing operations. This diversion of attention could have material and adverse consequences on our operations and profitability.

The terms of our credit agreements and other indebtedness from time to time require us to comply with a number of financial and other obligations, which may include maintaining debt service coverage and leverage ratios and maintaining insurance coverage, that impose significant operating and financial restrictions on us, including restrictions on our ability to take actions that may be in our interests. These obligations may limit our flexibility in our operations, and breaches of these obligations could result in defaults under the agreements or instruments governing the indebtedness, even if we had satisfied our payment obligations. Moreover, if we defaulted on these obligations, creditors having security interests over our assets could exercise various remedies,

We may not be able to successfully grow and expand. Successful implementation of our business plan will require management of growth, including potentially rapid and substantial growth, which could result in an increase in the level of responsibility for management personnel and strain on our human and capital resources. To manage growth effectively, we will be required, among other things, to continue to implement and improve our operating and financial systems, procedures, and controls and to expand, train, and manage our employee base. If we are unable to implement and scale improvements to our existing systems and controls in an efficient and timely manner or if we encounter deficiencies, we will not be able to successfully execute our business plans. Failure to attract and retain sufficient numbers of qualified personnel could also impede our growth. If we are unable to manage our growth effectively, it will have a material adverse effect on its business, results of operations, and financial condition.

The evolving nature of our business and rapid changes in the healthcare industry makes it difficult to anticipate the nature and amount of medical reimbursements, third partythird-party private payments, and participation in certain government programs and thus to reliably predict our future growth and operating results.

Under a capitation contract, a health plan typically prospectively pays an IPA periodic capitation payments based on a percentage of the amount received by the health plan. Capitation payments, in the aggregate, represent a prospective budget from which an IPA manages care-related expenses on behalf of the population enrolled with that IPA. If our affiliated IPAs are able to manage care-related expenses under the capitated levels, we realize operating profits from capitation contracts. However, if care-related expenses exceed projected levels, our affiliated IPAs may realize substantial operating deficits, which are not capped and could lead to substantial losses. Additionally, factors beyond our control, such as natural disasters, the potential effects of climate change, major epidemics, pandemics, or newly emergent viruses (such as the 2019 novel coronavirus, COVID-19), could reduce our ability to effectively manage the costs of providing health care.healthcare.

There are various state laws, including laws in California, regulating the corporate practice of medicine, which prohibit us from directly owning medical professional entities. These prohibitions are intended to prevent unlicensed persons from interfering with or inappropriately influencing a physician’s professional judgment. These and other laws may also prevent fee-splitting, which is the sharing of professional service income with non-professional or business interests. The interpretation and enforcement of these laws vary significantly from state to state. We currently derive revenues from MSAs or similar arrangements with our affiliated IPAs, whereby we provide management and administrative services to them. If these agreements and arrangements were held to be invalid under laws prohibiting the corporate practice of medicine and other laws or if there are new laws that prohibit such agreements or arrangements, a significant portion of our revenues will be lost, resulting in a material adverse effect on our results of operations and financial condition.

Because of corporate practice of medicine laws, we entered into contractual arrangements to manage certain affiliated physician practice groups, which allow us to consolidate those groups for financial reporting purposes. We do not have direct ownership interests in any of our VIEs and are not able to exercise rights as an equity holder to directly change the members of the boards of directors of these entities so as to affect changes at the management and operational level. Under our arrangements with our VIEs, we must rely on their equity holders to exercise our control over the entities. If our affiliated entities or their equity holders fail to perform as expected, we may have to incur substantial costs and expend additional resources to enforce such arrangements.

Our affiliated physician practice groups are owned by individual physicians who could die, become incapacitated, or become no longer affiliated with us. Although our MSAs with these affiliates provide that they will be binding on successors of

Our operations are dependent on a concentrated number of payors. Four payors accounted for an aggregate of 51.6%59.0% and 61.5%49.6% of our total net revenue for the years ended December 31, 20192022 and 2018,2021, respectively. We believe that a majority of our revenues will continue to be derived from a limited number of key payors, which may terminate their contracts with us, or our physicians credentialed by them, upon the occurrence of certain events. They may also amend the material terms of the contracts under certain circumstances. Failure to maintain such contracts on favorable terms, or at all, would materially and adversely affect our results of operations and financial condition.

A material decline in the number of patients that we and our affiliated physician groups serve, whether a government or a private entity is paying for their healthcare, could have a material adverse effect on our results of operations and financial condition, which could result from increased competition, new developments in the healthcare industry, or regulatory overhauls. In light of the repeal of the individual mandate requirement under the Patient Protection and Affordable Care Act of 2010 (also known as Affordable Care Act or Obamacare) via the Tax Cuts and Jobs Act of 2017, starting in 2019, some people are expected to lose their health insurance and thus may not continue to afford services by our managed medical groups. In addition, due to potential decreased availability of healthcare through private employers, the number of patients who are uninsured or participate in governmental programs may increase. A shift in payor mix from managed care and other private payors to government payors or the uninsured may result in a reduction in our rates of reimbursement or an increase in our uncollectible receivables or uncompensated care, with a corresponding decrease our net revenue. Changes in the eligibility requirements for governmental programs could also change the number of patients who participate in such programs or the number of uninsured patients. For those patients who remain with private insurance, changes in those programs could increase patient responsibility amounts, resulting in a greater risk for uncollectible receivables. Such events could have a material adverse effect on our business, results of operations and financial condition.

Our success depends to a significant extent on the continued contributions of our key management personnel, particularly our Executive Chairman and Co-Chief Executive Officer, Dr. Sim, and our Co-Chief Executive Officer and President, Dr. Lam, and our Co-Chief Executive Officer Brandon Sim for the management of our business and implementation of our business strategy. The loss of their services could have a material adverse effect on our business, financial condition, and results of operations.

There are various state laws, including laws in California, regulating the corporate practice of medicine, which prohibitsprohibit us from owning various healthcare entities. These corporate practice of medicine prohibitions are intended to prevent unlicensed persons from interfering with or inappropriately influencing a physician’s professional judgment. The interpretation and enforcement of these laws vary significantly from state to state. As a result, many of our affiliated physician practice groups are either wholly-ownedwholly owned or primarily owned by Dr. Lam as the nominee shareholder for our benefit. If these arrangements were held to be invalid under applicable laws, which may change from time to time, a significant portion of our consolidated revenues would be affected, which may result in a material adverse effect on our results of operations and financial condition. Similarly, if Dr. Lam died, was incapacitated, or otherwise was no longer affiliated with us, our relationships and arrangements with those VIEs could be in jeopardy, and our business could be adversely affected.

Our business relies in part on referrals from third parties for our services. We receive referrals from community medical providers, emergency departments, payors, and hospitals in the same manner as other medical professionals receive patient referrals. We do not provide compensation or other remuneration to referral sources for referring patients to us. A decrease in these referrals due to competition, concerns about our services and other factors could result in a significant decrease in our revenues and adversely impact our financial condition. Similarly, we cannot assure that we will be able to obtain or maintain preferred provider status

Our hospitalist physician services net revenue is derived from contracts directly with hospitals and other inpatient and post-acute care facilities. Our current partner facilities may decide not to renew contracts with, impose unfavorable terms on, or reduce fees paid to our affiliated physician groups. Any of these events may impact the ability of our affiliated physician groups to operate at such facilities, which would negatively impact our revenues, results of operations, and financial condition.

Many of our agreements with hospitals and medical groups are limited in their terms or may be terminated without cause by providing advance notice. If such agreements are not renewed or terminated, we would lose the revenue generated by them. Any such events could have a material adverse effect on our results of operations, financial condition, and future business plans. Because many of such agreements with hospitals and medical groups prohibit us from acquiring physicians or patients from or competing with them, our ability to hire physicians, attract patients, or conduct business in certain areas may be limited in some cases.

We depend on a complex, specialized, integrated management information system and standardized procedures for operational and financial information, as well as for our billing operations. We may be unable to enhance existing management information systems or implement new management information systems when necessary. We may experience unanticipated delays, complications, or expenses in implementing, integrating, and operating our systems. Our management information systems may require modifications, improvements, or replacements that may require both substantial expenditures, as well as interruptions in operations. Our ability to create and implement these systems depends on the availability of technology and skilled personnel. Our failure to successfully implement and maintain all of our systems could undermine our ability to receive payments and otherwise have a material adverse effect on our business, results of operations, and financial condition. Our failure to successfully operate our billing systems could also lead to potential violations of healthcare laws and regulations.

Risks Relating to the Healthcare Industry.

We compete directly with national, regional, and local providers of inpatient healthcare for patients and physicians. There are many other companies and individuals currently providing health carehealthcare services, many of which have been in business longer and/or have substantially more resources. Since there are virtually no substantial capital expenditures required for providing health carehealthcare services, there are few financial barriers to entry into the healthcare industry. Other companies could enter the healthcare industry in the future and divert some or all of our business. On a national basis, our competitors include, but are not limited to, Team Health, EmCare, DaVita Medical GroupOptum, and Heritage, each of which has greater financial and other resources available to them. We also compete with physician groups and privately-owned health carehealthcare companies in local markets. In addition, our relationships with governmental and private third-party payors are not exclusive and our competitors have established or could seek to establish relationships with such payors to serve their covered patients. Competitors may also seek to compete with us for acquisitions, which could have the effect of increasing the price and reducing the number of suitable acquisitions, which would have an adverse impact on our growth strategy. Individual physicians, physician groups, and companies in other healthcare industry segments, including those with which we have contracts, and some of which have greater financial, marketing, and staffing resources, may become competitors in providing health carehealthcare services, and this competition may have a material adverse effect on our business operations and financial position.

We therefore may be unable to compete successfully and even after we expend significant resources.

Each time a new physician joins us or our affiliated groups, we must enroll the physician under our applicable group identification number for Medicare and Medicaid programs and for certain managed care and private insurance programs before we can receive reimbursement for services the physician renders to beneficiaries of those programs. The estimated time to receive approval for the enrollment is sometimes difficult to predict and, in recent years, the Medicare program carriers often have not issued these numbers to our affiliated physicians in a timely manner. These practices result in delayed reimbursement that may adversely affect our cash flows.

In general, our affiliated physicians may only provide services in a hospital where they have maintained certain credentials, also known as privileges, which are granted by the medical staff according to the bylaws of the hospital. The medical staff could decide that our affiliated physicians can no longer receive privileges to practice there. Such a decision would limit our ability to furnish services at the hospital, decrease the number of our affiliated physicians, or preclude us from entering new hospitals. In addition, hospitals may attempt to enter into exclusive contracts for certain physician services, which would reduce our access to patient populations within the hospital.

The medical services industry is undergoing significant changes with government and other third-party payors that are taking measures to reduce reimbursement rates or, in some cases, denying reimbursement altogether. There is no assurance that government or other third-party payors will continue to pay for the services provided by our affiliated medical groups. Furthermore, there has been, and continues to be, a great deal of discussion and debate about the repeal and replacement of existing government reimbursement programs, such as the ACA. As a result, the future of healthcare reimbursement programs is uncertain, making long-term business planning difficult and imprecise. The failure of government or other third partythird-party payors to cover adequately the medical services provided by us could have a material adverse effect on our business, results of operations, and financial condition.

Our business may be significantly and adversely affected by legislative initiatives aimed at or having the effect of reducing healthcare costs associated with Medicare and other government healthcare programs and changes in reimbursement policies. In order to participate in the Medicare program, weour affiliated provider groups must comply with stringent and often complex enrollment and reimbursement requirements.requirements, failing which the provider group’s participation in the federal health care programs may be terminated, or civil and/or criminal penalties may be imposed. These programs generally provide for reimbursement on a fee-schedule basis rather than on a charge-related basis. As a result, we cannot increase our revenue by increasing the amount that we and our affiliates charge for services. To the extent that our costs increase, we may not be able to recover the increased costs from these programs. In addition, cost containment measures in non-governmental insurance plans have generally restricted our ability to recover, or shift to non-governmental payors, these increased costs. In attempts to limit federal and state spending, there have been, and we expect that there will continue to be, a number of proposals to limit or reduce Medicare reimbursement for various services. For example, the Medicare Access and CHIP Reauthorization Act of 2015 made numerous changes to Medicare, Medicaid, and other healthcare relatedhealthcare-related programs, including new systems for establishing annual updates to Medicare rates for physicians’ services.

We derive significant revenue from third-party payors, and delays in payment or refunds to payors may adversely impact our net revenue. We assume the financial risks relating to uncollectible and delayed payments. In particular, we rely on some key governmental payors. Governmental payors typically pay on a more extended payment cycle, which could require us to incur substantial expenses prior to receiving corresponding payments. In the current healthcare environment, as payors continue to control expenditures for healthcare services, including through revising their coverage and reimbursement policies, we may continue to experience difficulties in collecting payments from payors that may seek to reduce or delay such payments. If we are not timely paid in full or if we need to refund some payments, our revenues, cash flows, and financial condition could be adversely affected.

Decreases in payor rates, either prospectively or retroactively, could have a significant adverse effect on our revenues, cash flows, and results of operations.

We use third-party collection agencies whom we do not control to collect from patients any co-payments and other payments for services that our physicians provide. The federal Fair Debt Collection Practices Act of 1977 (the “FDCPA”) restricts the methods that third-party collection companies may use to contact and seek payment from consumer debtors regarding past due accounts. State laws vary with respect to debt collection practices, although most state requirements are similar to those under the FDCPA. Therefore, such agencies may not be successful in collecting payments owed to us and our affiliated physician groups. If practices of collection agencies utilized by us are inconsistent with these standards, we may be subject to actual damages and penalties. These factors and events could have a material adverse effect on our business, results of operations, and financial condition.

We establish reserves for estimated IBNR claims. IBNR estimates are developed using actuarial methods and are based on many variables, including the utilization of health carehealthcare services, historical payment patterns, cost trends, product mix, seasonality, changes in membership, and other factors. The estimation methods and the resulting reserves are periodically reviewed and updated.

Many of our contracts are complex in nature and may be subject to differing interpretations regarding amounts due for the provision of various services. Such interpretations may not come to light until a substantial period of time has passed. The inherent difficulty in interpreting contracts and estimating necessary reserves could result in significant fluctuations in our estimates from period to period. Our actual losses and related expenses therefore may differ, even substantially, from the reserve estimates reflected in our financial statements. If actual claims exceed our estimated reserves, we may be required to increase reserves, which would lead to a reduction in our assets or net income.

We depend on our affiliated physicians to provide services and generate revenue. We compete with many types of healthcare providers, including teaching, research and government institutions, hospitals, and other practice groups, for the services of clinicians and management personnel. The limited number of residents and other licensed providers on the job market with the expertise necessary to provide services within our business makes it challenging to meet our hiring needs and may require us to train new employees, contract temporary physicians, or offer more attractive wage and benefit packages to experienced professionals, which could decrease our profit margins. The limited number of available residents and other licensed providers also impacts our ability to renew contracts with existing physicians on acceptable terms. As a result, our ability to provide services could be adversely affected. Even though our physician turnover rate has remained stable over the last three years, if the turnover rate were to increase significantly, our growth could be adversely affected. Moreover, unlike some of our competitors who sometimes pay additional compensation to physicians who agree to provide services exclusively to that competitor, our affiliated IPAs have historically not entered into such exclusivity agreements and have allowed our affiliated physicians to affiliate with multiple IPAs. This practice may place us at a competitive disadvantage regarding the hiring and retention of physicians relative to those competitors who do enter into such exclusivity agreements.

The role of technology is greatly increasing in the delivery of healthcare, which makes it difficult for traditional physician-driven companies, such as us, to adopt and integrate electronic health records, databases, cloud-based billing systems, and many other technology applications in the delivery of healthcare services. Additionally, consumers are using mobile applications and care and cost research in selecting and usage of healthcare services. We may need to incur significant costs to implement these technology applications and comply with applicable laws. For example, the nature of our business and the requirements of healthcare privacy laws impose significant obligations on us to maintain privacy and protection of patient medical information. We rely on employees and third parties with technology knowledge and expertise and could be at risk if technology applications are not properly established, maintained, or secured. Any cybersecurity incident, even unintended, could expose us to significant fines and remediation costs and materially impair our business operations and financial position.

Due to the importance of the healthcare industry in the lives of all Americans, federal, state, and local legislative bodies frequently pass legislation and promulgate regulations relating to healthcare reform or that affect the healthcare industry. As has been the trend in recent years, it is reasonable to assume that there will continue to be increased government oversight and regulation of the healthcare industry in the future. We cannot assure our stockholders as to the ultimate content, timing, or effect of any new healthcare legislation or regulations, nor is it possible at this time to estimate the impact of potential new legislation or regulations on our business. It is possible that future legislation enacted by Congress or state legislatures, or regulations promulgated by regulatory authorities at the federal or state level, could adversely affect our business or could change the operating environment of the hospitals and other facilities where our affiliated physicians provide services. It is possible that the changes to the Medicare, Medicaid, or other governmental healthcare program reimbursements may serve as precedent to possible changes in other payors’ reimbursement policies in a manner adverse to us. Similarly, changes in private payor reimbursements could lead to adverse changes in Medicare, Medicaid, and other governmental healthcare programs, which could have a material adverse effect on our business, financial condition, and results of operations.

Although we do not anticipate that a single-payer national health insurance system will be enacted by the current Congress, several legislative initiatives have been proposed by members of Congress and presidential candidates that would establish some form of a single public or quasi-public agency that organizes healthcare financing, but under which healthcare delivery would remain private. If enacted, such a system could adversely affect our business.

Risks Relating to NGACO.GPDC/ACO REACH.

Under the AIPBPTCC mechanism, CMS estimates the total annual Part A and Part B Medicare expenditures of our assigned Medicare beneficiaries and paypays us that projected amount in per beneficiary per month payments. We chose “Risk Arrangement A,” comprising 80%the Global risk track, under which we assume 100% risk for Part A and Part B Medicare expenditures and awhere shared savings and losses capare less than 25% of 5% (or a 4% effectivethe benchmark, with adjusted risk corridors taking effect for any portion of shared savingssavings/losses equaling or exceeding 25% of the benchmark—for savings/losses of 25-35%, we assume 50% risk, for savings/losses 35%-50% we assume 25% of the risk, and for savings/losses cap when factoring in 80% risk impact).exceeding 50% of the benchmark, we assume only 10% of the risk. Our preliminary benchmark for Medicare Part A and Part B expenditures for beneficiaries for the 20192023 performance year, areper CMS, is approximately $410.0 million, and$629.2 million. Therefore, under “Risk Arrangement A”the Global risk track of the AIPBPTCC mechanism, we could therefore have profits or be liable for losses of up to 4%100% of the first 25% of such benchmarked expenditures, or approximately $16.4 million.$157.3 million, with adjusted risk corridors taking effect afterwards. While performance can be monitored throughout the year, end results for the 2019any given performance year will not be known until mid-2020.the third quarter of the subsequent year.

AIPBPGPDC / ACO REACH operations and benchmarking calculations are complex and can lead to errors in the application of the NGACOGPDC / ACO REACH Model, which could create reimbursement delays to our contracted, in-network providers and adversely affect our performance and results of operations. For example, historically under the NGACO program, we discovered a feature in the AIPBP claim processing system that doesdid not allow us to break down certain claims amounts by individual patient codes. This has created confusion for our in-network providers in reconciling payments, causing some providers to terminate their agreements with us. This featureThere is no guarantee that similar obstacles and other complexities withinwill be absent from the AIPBP mechanismGPDC / ACO REACH models, and could also create uncertainties for our operations, including under agreements with our contracted, in-network providers providers.

Through the NGACOGPDC / ACO REACH Model, CMS provides an opportunity to provider groups that are willing to assume higher levels of financial risk and reward, to participate in this new attribution-based risk sharingrisk-sharing model. The NGACOGPDC / ACO REACH Model uses a prospectively-set costprospectively set preliminary benchmark whichthat is established prior toretrospectively adjusted at the startend of eachthe performance year. The preliminary benchmark is based on various factors, includingbaseline historical expenditures by Participant Providers in the benchmark years trended forward using the US Per Capita Cost (“USPCC”) growth trend, and subsequently blended with regional expenditure rates, which are contained in the ACO REACH / Kidney Care Choices (“KCC”) Rate Book. The benchmark years are set at CY2017-2019 for the duration of the model. In PY2023, historical baseline expenditures withare weighted at 65%, regional expenditures are weighted at 35%, and historical expenditures will be weighted less in future performance years. For full details on how the baseline updated eachpreliminary benchmark is calculated, please refer to CMS documentation. After the performance year to reflectconcludes, the NGACO’s participant listpreliminary benchmark is adjusted for numerous factors, such as the ACO’s final risk score and beneficiaries who became ineligible for the givenprogram over the course of the performance year. Our 2019 performance year baselineIf necessary at this stage, a Retrospective Trend Adjustment (“RTA”) may be applied as well. An RTA is basedapplied if the USPCC trend differs by at least 1% from the observed expenditure trend in the National Reference Population. It adjusts the benchmark by the difference between the observed expenditure trend and the predicted USPCC trend. Once all adjustments are made to the preliminary benchmark, APAACO’s expenditures will be compared to this final benchmark to calculate shared savings or shared losses. For full details on calendar year 2018 expenditures that are risk adjusted and trended. A discounthow the final benchmark is then applied that incorporates regional and national efficiency. The benchmarked expenditures therefore could potentially underestimate our actual expenditures for assigned Medicare beneficiaries and there can be no assurance that we could successfully

Medicare beneficiaries in the NGACOGPDC / ACO REACH Model are not required to receive care from a specified network of contracted providers and facilities, which could make it difficult for us to control the financial risks of those beneficiaries. CMS notified us that its Medicare beneficiaries historically had received approximately 62% of care at non-contracted, out-of-network (“OON”) providers. While we are not responsible for directly paying claims for OONout-of-network providers, we may have difficulty managing patient care and costs in relation to such OONout-of-network providers as compared to contracted, in-network providers, which, could adversely impact our financial results as we are responsible for savings and losses of assigned beneficiaries, irrespective of whether they are using in-network or OONout-of-network providers. In addition, even if we are successful in encouraging more assigned patients to receive care from our contracted, in-network providers, there is the possibility that the monthly AIPBPTCC from CMS will be insufficient to cover our expenditures, since the AIPBPTCC is generally based on historical in-network/out-of-network ratios. If CMS fails to monitor the in-network/OONout-of-network provider ratio for our assigned patients on a frequent basis, or CMS’ reconciliation payments to us are not timely made, this could result in negative cash flows for us, especially if increased payments will need to be made to our contracted, in-network providers.

Managed care providers experienced in coordinating care for populations of patients compete with each other to be selected by CMS to participate in the NGACOACO REACH Model. Since MSSP and pioneer ACOs began in 2012, the number of Medicare ACOs continues to rise and have grown to several hundred nationwide, but there are still a growing number of ACOs in different program types that compete with us for resources and patients.

APAACO and CMS entered into a Next Generation ACO Model Participation Agreement (the “Participation Agreement”) with a term of twofour performance years through December 31, 2018.2020. Subsequently due to the COVID-19 Public Health Emergency, the Next Generation ACO Model Participation Agreement was amended to add one additional 12-month Performance Year, such that the final Performance Year ended on December 31, 2021. For PY2022, we were approved to participate in the GPDC Model, which was subsequently transitioned to ACO REACH for performance year 2023. APAACO participated in the GPDC Model in 2022 and has an active participation agreement with CMS and APAACO has renewedfor 2023. However, the Participation Agreement for an additional year with the option for a second renewal year through December 31, 2020. In addition, the Participation AgreementGPDC / ACO REACH Model may be terminated sooner by CMS as specified therein and CMS has the flexibility to alter or change the program over time. Among many requirements to be eligible to participate in the NGACOACO REACH Model, we must have at least 10,0005,000 aligned Medicare beneficiaries and must maintain that number throughout each performance year. Although we started the 2019 performance year with more than 29,000 aligned Medicare beneficiaries, there can be no assurance that we will maintain the required number of assigned Medicare beneficiaries. If that number were not maintained, we would become ineligible for the NGACOACO REACH Model. In addition, we are required to comply with all applicable laws and regulations regarding provider-based risk-bearing entities. If these laws or regulations change, for example, to require a Knox-Keene license in California, which we do not currently have, we could be required to cease our NGACOACO REACH operations. We could be terminated from the NGACOACO REACH Model at any time if we do not continue to comply with the NGACOACO REACH participation requirements. In October 2017, CMS notified us that our participation in the AIPBP mechanism for performance year 2018 would not be renewed due to alleged deficiencies in performance by us. We submitted a request for reconsideration to CMS. In December 2017, we received the official decision on our reconsideration request that CMS reversed the prior decision against our continued participation in the AIPBP mechanism. As a result, we were again eligible to receive monthly AIPBP from CMS. We, however, will need to continue to comply with all terms and conditions in the Participation Agreement and various regulatory requirements to be eligible to participate in the AIPBP

Risks Relating to Regulatory Compliance.

Some states have laws that prohibit business entities from practicing medicine, employing physicians to practice medicine, exercising control over medical decisions by physicians (also known collectively as the corporate practice of medicine) or engaging in some arrangements, such as fee-splitting, with physicians. In some states these prohibitions are expressly stated in a statute or regulation, while in other states the prohibition is a matter of judicial or regulatory interpretation. California is one of the states that prohibit the corporate practice of medicine.

In California, we operate by maintaining contracts with our affiliated physician groups, which are each owned and operated by physicians, and which employ or contract with additional physicians to provide physician services. Under these arrangements, we or our subsidiaries provide management services, receive a management fee for providing management services, do not represent to offer medical services, and do not exercise influence or control over the practice of medicine by the physicians or the affiliated physician groups.

In addition to the above management arrangements, in certain instances, we have contractual rights relating to the transfer of equity interests in our affiliated physician groups under physician shareholder agreements that we entered into with the controlling equity holder of such affiliated physician groups. However, even in such instances, such equity interests cannot be transferred to or held by us or by any non-professional organization. Accordingly, we do not directly own any equity interests in any affiliated physician groups in California. In the event that any of these affiliated physician groups or their equity holders fail to comply with these management or ownership transfer arrangements, these arrangements are terminated, we are unable to enforce such arrangements, or these arrangements are invalidated under applicable laws, there could be a material adverse effect on our business, results of operations, and financial condition and we may have to restructure our organization and change our arrangements with our affiliated physician groups, which may not be successful.

As a company involved in providing healthcare services, we are subject to numerous federal, state, and local laws and regulations. There are significant costs involved in complying with these laws and regulations. If we are found to have violated any applicable laws or regulations, we could be subject to civil and/or criminal damages, fines, sanctions, or penalties, including exclusion from participation in governmental healthcare programs, such as Medicare and Medicaid, and we may be required to change our method of operations and business strategy. These consequences could be the result of our current conduct or even conduct that occurred a number of years ago, including prior to the completion of the 2017 Merger. We could incur significant costs to defend ourselves if we become the subject of an investigation or legal proceeding alleging a violation of these laws and regulations. We cannot predict whether a federal, state, or local government will determine that we are not operating in accordance with law, or whether, when or how the laws will change in the future and impact our business. The following is a non-exhaustive list of some of the more significant healthcare laws and regulations that could affect us:

Any violation or alleged violation of any of these laws or regulations by us or our affiliates could have a material adverse effect on our business, financial condition and results of operations.

Any changes in healthcare laws or regulations that reduce, curtail, or eliminate payments, government-subsidized programs, government-sponsored programs, and/or the expansion of Medicare or Medicaid, among other actions, could have a material adverse effect on our business, results of operations, and financial condition.

For example, the ACA dramatically changed how healthcare services are covered, delivered, and reimbursed. The ACA requires insurers to accept all applicants, regardless of pre-existing conditions, cover an extensive list of conditions and treatments, and charge the same rates, regardless of pre-existing condition or gender. The ACA and the Health Care and Education Reconciliation Act of 2010 (collectively, the “Health Care Reform Acts”) also mandated changes specific to home health and hospice benefits under Medicare. In 2012, the U.S. Supreme Court upheld the constitutionality of the ACA, including the “individual mandate” provisions of the ACA that generally require all individuals to obtain healthcare insurance or pay a penalty. However, the U.S. Supreme Court also held that the provision of the ACA that authorized the Secretary of the U.S. Department of Health and Human Services (“HHS”) to penalize states that choose not to participate in the expansion of the Medicaid program by removing all of its existing Medicaid funding was unconstitutional. In response to the ruling, a number of state governors opposed its state’s participation in the expanded Medicaid program, which resulted in the ACA not providing coverage to some low-income persons in those states. In addition, several bills have been, and are continuing to be, introduced in U.S. Congress to amend all or significant provisions of the ACA, or repeal and replace the ACA with another law. In December 2017, the individual mandate was repealed via the Tax Cuts and Jobs Act of 2017. Afterwards, legal and political challenges as to the constitutionality of the remaining provisions of the ACA resumed. Just as the fate of the ACA is uncertain, so is the future of care organizations established under the ACA such as ACOs and NGACOs. Under its NGACO Participation Agreement with CMS, our operations are always subject to the nation’s healthcare laws, as amended, repealed, or replaced from time to time.

The net effect of the ACA on our business is subject to numerous variables, including the law’s complexity, lack of complete implementing regulations and interpretive guidance, gradual and potentially delayed implementation, or possible amendment, as well as the uncertainty as to the extent to which states will choose to participate in the expanded Medicaid program. The continued implementation of provisions of the ACA, the adoption of new regulations thereunder and ongoing challenges thereto, also added uncertainty about the current state of U.S. healthcare laws and could negatively impact our business, results of operations, and financial condition.

Due to our and our affiliates’ participation in government and private healthcare programs, we are from time to time involved in inquiries, reviews, audits, and investigations by governmental agencies and private payors of our business practices, including assessments of our compliance with coding, billing, and documentation requirements. Federal and state government agencies have active civil and criminal enforcement efforts against healthcare companies, and their executives and managers. The DRA, which provides a financial incentive to states to enact their own false claims acts, and similar laws encourage investigations against healthcare companies by different agencies. These investigations could also be initiated by private whistleblowers. Responding to audit and investigative activities are costly and disruptive to our business operations, even when the allegations are without merit. If we are subject to an audit or investigation, a finding could be made that we or our affiliates erroneously billed or were incorrectly reimbursed, and we may be required to repay such agencies or payors, may be subjected to pre-payment reviews, which can be time-consuming and result in non-payment or delayed payments for the services we or our affiliates provide, and may be subject to financial sanctions or required to modify our operations.

Controls imposed by Medicare, Medicaid, and private payors designed to reduce admissions and lengths of stay, commonly referred to as “utilization review,” have affected and are expected to continue to affect our operations. Federal law contains numerous provisions designed to ensure that services rendered by hospitals and other care providers to Medicare and Medicaid patients meet professionally recognized standards and are medically necessary and that claims for reimbursement are properly filed. These provisions include a requirement that a sampling of admissions of Medicare and Medicaid patients must be reviewed by quality improvement organizations, which review the appropriateness of Medicare and Medicaid patient admissions and discharges, the quality of care provided, and the appropriateness of cases of extraordinary length of stay or cost on a post-discharge basis. Quality improvement organizations may deny payment for services or assess fines and also have the authority to recommend to the HHS that a provider is in substantial noncompliancenon-compliance with the standards of the quality improvement organization and should be excluded from participation in the Medicare program. The ACA potentially expands the use of prepayment review by Medicare contractors by eliminating statutory restrictions on its use, and, as a result, efforts to impose more stringent cost controls are expected to continue. Utilization review is also a requirement of most non-governmental managed care organizations and other third-party payors. Inpatient utilization, average lengths of stay and occupancy rates continue to be negatively affected by payor-required preadmissionpre-admission authorization and utilization review and by third partythird-party payor pressure to maximize outpatient and alternative healthcare delivery services for less acutely ill patients. Although we are unable to predict the effect these controls and any changes thereto may have on our operations, significant limits on the scope of our services reimbursed and on reimbursement rates and fees could have a material, adverse effect on our business, financial position, and results of operations.

The Knox-Keene Health Care Service Plan Act of 1975 was passed by the California State Legislature to regulate California managed care plans and is currently administered by the DMHC. A Knox-Keene Act license is required to operate a health carehealthcare service plan, e.g., an HMO, or an organization that accepts global risk, i.e., accepts full risk for a patient population, including risk related to institutional services, e.g., hospital, and professional services. Applying for and obtaining such a license is a time consumingtime-consuming and detail-oriented undertaking. We currently do not hold any Knox-Keene license. If the DMHC were to determine that we have been inappropriately taking risk for institutional and professional services as a result of our various hospital and physician arrangements without having any Knox-Keene license or applicable regulatory exemption, we may be required to obtain a Knox-Keene license and could be subject to civil and criminal liability, any of which could have a material adverse effect on our business, results of operations, and financial condition.

The DMHC has instituted financial solvency regulations. The regulations that are intended to provide a formal mechanism for monitoring the financial solvency and operational performance of a RBO in California, including capitated physician groups. Under current DMHC regulations, our affiliated physician groups, as applicable, are required to, among other things:

In the event that a physician group is not in compliance with any of the above criteria, it would be required to describe in a report submitted to the DMHC the reasons for non-compliance and actions to be taken to bring it into compliance. Under such regulations, the DMHC can also make some of the information contained in the reports public, including, but not limited to, whether or not a particular physician organization met each of the criteria. In the event any of our affiliated physician groups are not able to meet certain of the financial solvency requirements, and fail to meet subsequent corrective action plans, it could be subject to sanctions, or limitations on, or removal of, its ability to do business in California. There can be no assurance that our affiliated physician groups, such as our IPAs, will remain in compliance with DMHC requirements or be able to timely and

We rely upon our affiliated physicians to appropriately and accurately complete necessary medical record documentation and assign appropriate reimbursement codes for their services. Reimbursement is conditioned upon, in part, our affiliated physicians providing the correct procedure and diagnosis codes and properly documenting the services themselves, including the level of service provided and the medical necessity for the services. If our affiliated physicians have provided incorrect or incomplete documentation or selected inaccurate reimbursement codes, this could result in nonpaymentnon-payment for services rendered or lead to allegations of billing fraud. This could subsequently lead to civil and criminal penalties, including exclusion from government healthcare programs, such as Medicare and Medicaid. In addition, third-party payors may disallow, in whole or in part, requests for reimbursement based on determinations that certain amounts are not covered, services provided were not medically necessary, or supporting documentation was not adequate. Retroactive adjustments may change amounts realized from third-party payors and result in recoupments or refund demands, affecting revenue already received.

It is common in the medical services industry for primary care physicians to be affiliated with multiple IPAs. Our affiliated IPAs therefore may enter into agreements with physicians who are also affiliated with our competitors. However, some of our competitors at times have agreements with physicians that require the physician to provide exclusive services. Our affiliated IPAs often have no knowledge, and no way of knowing, whether a physician is subject to an exclusivity agreement without being informed by the physician. Competitors have initiated lawsuits against us alleging in part interference with such exclusivity arrangements, and may do so again in the future. An adverse outcome from any such lawsuit could adversely affect our business, cash flows, and financial condition.

Individuals and entities can be excluded from participating in the Medicare and Medicaid programs for violating certain laws and regulations, or for other reasons such as the loss of a license in any state, even if the person retains other licensure. This means that the excluded person and others are prohibited from receiving payments for such person’s services rendered to Medicare or Medicaid beneficiaries, and if the excluded person is a physician, all services ordered (not just provided) by such physician are also non-covered and non-payable. Entities whichthat employ or contract with excluded individuals are prohibited from billing the Medicare or Medicaid programs for the excluded individual’s services, and are subject to civil penalties if it does. The U.S. Department of Health and Human Services Office of the Inspector General maintains a list of excluded persons. Although we have instituted policies and procedures to minimize such risks, there can be no assurance that we will not inadvertently hire or contract with an excluded person, or that our employees or contracts will not become excluded in the future without our knowledge. If this occurs, we may be subject to substantial repayments and civil penalties, and the hospitals at which we furnish services may also be subject to repayments and sanctions, for which they may seek recovery from us, which could adversely affect our business, cash flows, and financial condition.

We must comply with various federal and state laws and regulations governing the collection, dissemination, access, use, security, and confidentiality of PHI, including HIPAA and HITECH. As part of our medical record keeping, third-party billing, and other services, we collect and maintain PHI in paper and electronic format. Privacy and data security laws and regulations thus could have a significant effect on the manner in which we handle healthcare-related data and communicates with payors. In addition, compliance with these standards could limit our ability to offer services, thereby negatively impacting the business opportunities available to us. Despite our efforts to prevent privacy and security breaches, it may still occur. If any non-compliance with such laws and regulations results in privacy or security breaches, we could be subject to monetary fines, suits, penalties, or sanctions. As a result of the expanded scope of HIPAA through HITECH, we may incur significant costs in order to minimize the amount of “unsecured PHI” that we handle and retain, and/or to implement improved administrative, technical, or physical safeguards to protect PHI. We may have to demonstrate and document our compliance efforts, even if there is a low probability that PHI has been compromised, in order to overcome the presumption that an impermissible use or disclosure of PHI results in a reportable breach. We may incur significant costs to notify the relevant individuals, government entities and, in some cases, the media, in the event of a breach and to provide appropriate remediation and monitoring to mitigate any potential damage.

A plaintiffs’ securities law firm announced that it was investigating ApolloMed and its pre-Mergerpre-2017 Merger board of directors for potential federal law violations and breaches of fiduciary duties in connection with the 2017 Merger. This investigation purportedly focused on whether ApolloMed and its board of directors violated federal securities laws or breached their fiduciary duties to ApolloMed’s stockholders by failing to properly value the 2017 Merger and failing to disclose all material information in connection with the 2017 Merger. As of filing of this Annual Report on Form 10-K, no lawsuit has been filed against us by that firm.

We cannot preclude the possibility that claims or lawsuits brought relating to any alleged securities law violations or breaches of fiduciary duty in connection with the 2017 Merger could potentially require significant time and resources to defend and/or settle and distract our management and board of directors from focusing on our business.

We are exposed to and become involved in various litigation matters arising out of our business, including from time to time, actual or threatened lawsuits. Malpractice lawsuits are common in the healthcare industry. The medical malpractice legal environment varies greatly by state. The status of tort reform, availability of non-economic damages, or the presence or absence of other statutes, such as elder abuse or vulnerable adult statutes, influence the incidence and severity of malpractice litigation. We may also be subject to other types of lawsuits, such as those initiated by our competitors, stockholders, employees, service providers, contractors, or by government agencies, including when we terminate relationships with them, which may involve large claims and significant defense costs. Many states have joint and several liabilities for providers who deliver care to a patient and are at least partially liable. As a result, if one provider is found liable for medical malpractice for the provision of care to a particular patient, all other providers who furnished care to that same patient, including possibly us and our affiliated physicians, may also share in the liability, which could be substantial individually or in aggregate.

The defense of litigation, including fees of legal counsel, expert witnesses, and related costs, is expensive and difficult to forecast accurately. Such costs may be unrecoverable even if we ultimately prevail in litigation and could consume a significant portion of our limited capital resources. To defend lawsuits, it may also be necessary for us to divert officers and other employees from our normal business functions to gather evidence, give testimony, and otherwise support litigation efforts. If we lose any material litigation, we could face material judgments or awards against them. An unfavorable resolution of one or more of the proceedings in which we are involved now or in the future could have a material adverse effect on our business, cash flows, and financial condition. We may also in the future find it necessary to file lawsuits to recover damages or protect our interests. The cost of such litigation could also be significant and unrecoverable, which may also deter us from aggressively pursuing even legitimate claims.

We currently maintain malpractice liability insurance coverage to cover professional liability and other claims for certain hospitalists and clinic physicians. All of our affiliated physicians are required to carry first dollar coverage with limits of coverage equal to $1,000,000$1.0 million for all claims based on occurrence up to an aggregate of $3,000,000$3.0 million per year. We cannot be certain that our insurance coverage will be adequate to cover liabilities arising out of claims asserted against us, our affiliated professional organizations, or our affiliated physicians. Liabilities incurred by us or our affiliates in excess of our insurance coverage, including coverage for professional liability and other claims, could have a material adverse effect on our business, financial condition, and results of operations. Our professional liability insurance coverage generally must be renewed annually and may not continue to be available to us in future years at acceptable costs and on favorable terms, which could increase our exposure to litigation.

Certain regulations not specifically targeting the healthcare industry also could have material effects on our operations. For example, the California Finance Lenders Law (the “CFLL”), Division 9, Sections 22000-22780 of the California Financial Code, could be applied to us as a result of our various affiliate and subsidiary loans and similar arrangements. If a regulator were to take the position that such loans were covered by the California Finance Lenders Law, we could be subject to regulatory action whichthat could impair our ability to continue to operate and may have a material adverse effect on our profitability and business as we currently do not hold a CFLL licensure. Pursuant to an exemption under the CFLL, a person may make five or fewer commercial loans in a 12-month period without a CFLL licensure if the loans are “incidental” to the business of the person. This exemption, however, creates some uncertainty as to which loans could be deemed as incidental to our business. In addition, a person without

Risks Relating to the Ownership of ApolloMed’s Common Stock.

As a public company, ApolloMed is required to comply with various regulatory and reporting requirements, including those required by the SEC. AfterBecause ApolloMed uplisted to NASDAQ in December 2017, it is also subject to NASDAQ listing rules. Complying with these requirements is time-consuming and expensive. No assurance can be given that ApolloMed can continue to meet the SEC reporting and NASDAQ listing requirements.

The trading price of ApolloMed’s common stock was volatile and may continue to be so from time to time. The price at which ApolloMed’s common stock trades could be subject to significant fluctuation and may be affected by a variety of factors, including the trading volume, our results of operations, the announcement and consummation of certain transactions, our ability or inability to raise additional capital and the terms thereof, and therefore could fluctuate, and decline, significantly. Other factors that may cause the market price of ApolloMed’s common stock to fluctuate include:

There may continue to be a limited trading market for ApolloMed’s common stock. A lack of an active market may contribute to stock price volatility or supply/demand imbalances, make an investment in ApolloMed’s common stock less attractive to certain investors, and/or impair the ability of ApolloMed’s stockholders to sell shares at the time they desire or at a price that they consider favorable. The lack of an active market may also reduce the fair market value of ApolloMed’s common stock, impair our ability to raise capital by selling shares of ApolloMed’s common stock, or use such stock as consideration to attract and retain talent or engage in business transactions.

The trading market for ApolloMed’s common stock will rely in part on the availability of research and reports that third-party analysts publish about us. There are many large companies active in the healthcare industry, which make it more difficult for us to receive widespread coverage. Furthermore, if one or more of the analysts who do cover us downgrade ApolloMed’s common stock, its price would likely decline. If one or more of these analysts cease coverage of us, we could lose market visibility, which in turn could cause ApolloMed’s stock price to decline.

As of December 31, 2019,2022, our executive officers, directors, five percent or greater stockholders, and their respective affiliated entities in the aggregate own approximately 43.4%25.2% of our outstanding common stock. As a result, these stockholders, who are entitled to vote their shares in their own interests, acting together, exert a significant degree of influence over our management and affairs and over matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions. This concentration of ownership may have the effect of delaying or preventing a change of control, merger, consolidation, sale of all or substantially all of our assets or other corporate transactions that other stockholders may view as beneficial, or conversely, this concentrated control could result in the consummation of a transaction that other stockholders may not support. This may harm the value of our shares and discourage investors from investing in us.

ApolloMed is subject to Section 203 of the Delaware General Corporation Law, which makes the acquisition of ApolloMed and the removal of its incumbent officers and directors more difficult for potential acquirers by prohibiting stockholders holding 15% or more of its outstanding voting stock from acquiring it without the consent of its board of directors for at least three years from the date they first hold 15% or more of the voting stock. These provisions and others that could be adopted in the future could deter unsolicited takeovers or delay or prevent changes in ApolloMed’s control or management, including transactions in which ApolloMed’s stockholders might otherwise receive a premium for their shares over then current market prices. These provisions may also limit the ability of ApolloMed’s stockholders to approve transactions that they may deem to be in their best interests.

Additionally, ApolloMed’s charter and bylaws contain additional provisions, such as the authorization for its board of directors to issue one or more classes of preferred stock and determine the rights, preferences, and privileges of the preferred stock, which could cause substantial dilution to a person or group that attempts to acquire ApolloMed on terms not approved by the board, and the ownership requirement for ApolloMed’s stockholders to call special meetings, that could deter, discourage, or make it more difficult for a change in control of ApolloMed or for a third party to acquire ApolloMed, even if such a change in control could be deemed in the interest of ApolloMed’s stockholders, or if such an acquisition would provide ApolloMed’s stockholders with a substantial premium for their shares over the market price of ApolloMed’s common stock.

As such, these provisions could discourage a potential acquirer from acquiring us or otherwise attempting to obtain our control and increase the likelihood that our incumbent directors and officers will retain their positions.

None.

Our corporate headquarters isare located in Alhambra, California, where we lease and occupy approximately 35,000 square feet of office spaces in two neighboringadjacent buildings from an entity that shares certain common ownership with ApolloMed. The current lease for our headquarters is wholly owned and consolidated by APC as a result of an acquisition that occurred on a month-to-month basis and requires monthly rental payment of approximately $84,000.

We lease approximately 8,800 square feet of space in San Gabriel, California, which is the primary office for SCHC. The base rent for the space is approximately $33,000 per month, subject to adjustments, and for a term expiring in 2024 (or subject to the terms of the lease, in 2021).
