The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and in conjunction with the rules and regulations of the Securities and Exchange Commission (“SEC”). Any references in this report to the number of properties is outside the scope of our independent registered public accounting firm’s audit of our financial statements, in accordance with the standards of the Public Company Accounting Oversight Board. In the opinion of management, all adjustments of a normal and recurring nature necessary for a fair presentation of the consolidated financial statements have been made.

The Company consolidates real estate partnerships and other entities that are not variable interest entities (“VIEs”) in accordance with Accounting Standards Codification (“ASC”) 810, Consolidation (“ASC 810”), when it owns, directly or indirectly, a majority interest in the entity or is otherwise able to control the entity. Entities that are not VIEs and for which the Company owns an interest but does not consolidate are accounted for under the equity method of accounting as an investment in an unconsolidated entity and are included

The Company consolidates VIEs in accordance with ASC 810 if it is the primary beneficiary of the VIE as determined by its power to direct the VIE’s activities and the obligation to absorb its losses or the right to receive its benefits, which are potentially significant to the VIE. The Company holds investments in venture capital funds and deposits with land banking entities, which were determined to be VIEs. As the Company does not control the activities that most significantly impact the economic performance of these entities, the Company was deemed not to be the primary beneficiary and therefore did not consolidate the entities. The investments in the unconsolidated venture capital funds are accounted for under the equity method of accounting and included in escrow deposits, prepaid expenses and other assets within the consolidated balance sheets. As of December 31, 2022, the carrying value of the investments in these venture capital funds was $12.0 million and the Company’s maximum exposure to loss was $16.1 million, which includes all future capital funding requirements. See Land Option Contracts below for a further discussion of the deposits with land banking entities.

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

AMH has elected to be taxed as a REIT for U.S. federal income tax purposes under Sections 856 to 860 of the Internal Revenue Code of 1986, as amended (the “Code”), commencing with our taxable year ended December 31, 2012. We believe that we have operated, and continue to operate, in such a manner as to satisfy the requirements for qualification as a REIT. Provided that we qualify as a REIT and our distributions to our shareholders equal or exceed our REIT taxable income (determined without regard to the deduction for dividends paid and including any net capital gains), we generally will not be subject to U.S. federal income tax.

Qualification and taxation as a REIT depend upon our ability to meet the various qualification tests imposed under the Code, including tests related to the percentage of income that we earn from specified sources and the percentage of our earnings that we distribute to our shareholders. Accordingly, no assurance can be given that we will continue to be organized or be able to operate in a manner so as to remain qualified as a REIT. If we fail to qualify as a REIT in any taxable year and do not qualify for certain statutory relief provisions, we would be subject to U.S. federal income tax and state income tax on our taxable income at regular corporate tax rates, and we would likely be precluded from qualifying for treatment as a REIT until the fifth calendar year following the year in which we fail to qualify.

Even if we qualify as a REIT, we may be subject to certain state or local income and capital taxes and U.S. federal income and excise taxes on our undistributed REIT taxable income, if any. Certain of our subsidiaries are subject to taxation by U.S. federal, state and local authorities for the periods presented. We made joint elections to treat certain subsidiaries as taxable REIT subsidiaries which are subject to U.S. federal, state and local taxes on their income at regular corporate rates. The tax years from 2017 to present generally remain open to examination by the taxing jurisdictions to which the Company is subject.

We believe that our Operating Partnership is properly treated as a partnership for U.S. federal income tax purposes. As a partnership, the Operating Partnership is not subject to U.S. federal income tax on our income. Instead, each of the Operating Partnership’s partners, including AMH, is allocated, and may be required to pay tax with respect to, its share of the Operating Partnership’s income. As such, no provision for U.S. federal income taxes has been included for the Operating Partnership.

ASC 740-10, Income Taxes, requires recognition of deferred tax assets for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. We recognize tax benefits of uncertain tax positions only if it is more likely than not that the tax position will be sustained, based solely on its technical merits, with the taxing authority having full knowledge of all relevant information. The measurement of a tax benefit for an uncertain tax position that meets the more likely than not threshold is based on a cumulative probability model under which the largest amount of tax benefit recognized is the amount with a greater than 50%

As a REIT, we generally are required to distribute annually to our shareholders at least 90% of our REIT taxable income (determined without regard to the deduction for dividends paid and any net capital gains) and to pay tax at regular corporate rates to the extent that we annually distribute less than 100% of our REIT taxable income (determined without regard to the deduction for dividends paid and including any net capital gains). The Operating Partnership funds the payment of distributions. AMH had a net operating loss (“NOL”) for U.S. federal income tax purposes of an estimated $11.8 million as of December 31, 2022 and $25.4 million as of December 31, 2021. We intend to use our NOL (to the extent available) to reduce our REIT taxable income to the extent that REIT taxable income is not reduced by our deduction for dividends paid.

Purchases of single-family properties are treated as asset acquisitions and, as such, are recorded at their purchase price, including acquisition costs, which is allocated to land and building based upon their relative fair values at the date of acquisition. Fair value is determined in accordance with ASC 820, Fair Value Measurements and Disclosures, and is primarily based on unobservable data inputs. In making estimates of fair values for purposes of allocating the purchase price of individually acquired properties subject to an existing lease, the Company utilizes its own market knowledge obtained from historical transactions, its internal construction program (the “AMH Development Program”) and published market data. In this regard, the Company also utilizes information obtained from county tax assessment records to assist in the determination of the fair value of the land and building. Typically, we allocate between 10% to 30% of the purchase price of properties to land. For the year ended December 31, 2022, the Company purchased 1,605 single-family properties treated as asset acquisitions for accounting purposes for a total purchase price of $571.8 million, net of holding costs, which was included in cash paid for single-family properties within the consolidated statement of cash flows.

We incur costs to prepare properties acquired through our traditional acquisition channels for rental. These costs, along with related holding costs, are capitalized to the cost of the property during the period the property is undergoing activities to prepare it for its intended use. We capitalize interest costs as a cost of the property only during the period for which activities necessary to prepare an asset for its intended use are ongoing, provided that expenditures for the asset have been made and interest costs have been incurred. Upon completion of the renovation of our properties, all costs of operations, including repairs and maintenance, are expensed as incurred.

Land and construction in progress for our AMH Development Program are presented separately in single-family properties under development and development land within the consolidated balance sheets. Our capitalization policy on development properties follows the guidance in ASC 835-20, Capitalization of Interest, and ASC 970, Real Estate-General. Costs directly related to the development of properties are capitalized and the costs of land and buildings under development include specifically identifiable costs. We also capitalize interest, real estate taxes, insurance, utilities, and payroll costs for land and construction in progress under active development once the applicable GAAP criteria have been met.

Single-family properties and land lots are classified as held for sale when they meet the applicable GAAP criteria in accordance with ASC 360-10, Property, Plant, and Equipment—Overall, including, but not limited to, the availability of the home for immediate sale in its present condition, the existence of an active program to locate a buyer and the probable sale of the home within one year. Single-family properties and land lots are classified as held for sale are reported at the lower of their carrying value or estimated fair value less costs to sell, and are presented separately in single-family properties held for sale, net within the consolidated balance sheets. As of December 31, 2022 and 2021, the Company had 1,115 and 659 single-family properties, respectively, classified as held for sale, and recorded $2.5 million, $0.2 million and $2.0 million of impairment on single-family properties held for sale for the years ended December 31, 2022, 2021 and 2020, respectively, which is included in gain on sale and impairment of single-family properties and

other, net within the consolidated statements of operations. The results of operations of properties that have either been sold or classified as held for sale, if due to a strategic shift that has (or will have) a major effect on our operations or financial results, are reported in the consolidated statements of operations as discontinued operations for both current and prior periods presented through the date of the applicable disposition in accordance with ASC 205-20, Presentation of Financial Statements—Discontinued Operations. During the years ended December 31, 2022, 2021 and 2020, none of the properties classified as held for sale met the criteria to be reported as a discontinued operation.

We evaluate our long-lived assets for impairment periodically or whenever events or circumstances indicate that their carrying amount may not be recoverable. Significant indicators of impairment may include, but are not limited to, declines in home values, rental rates and occupancy percentages, as well as significant changes in the economy. If an impairment indicator exists, we compare the expected future undiscounted cash flows against the net carrying amount. If the sum of the estimated undiscounted cash flows is less than the net carrying amount, we record an impairment loss for the difference between the estimated fair value of the individual property and the carrying amount of the property at that date. No significant impairments on operating properties were recorded during the years ended December 31, 2022, 2021 and 2020.

We enter into land option contracts to acquire the right to purchase land for our AMH Development Program. Under these contracts, we typically make a specified option payment or deposit in consideration for the right to purchase land in the future, usually at a predetermined price. We analyze these land option contracts under the variable interest model to determine whether the land seller is a VIE and, if so, whether we are the primary beneficiary. Although the Company does not have legal title to the underlying land, we may be required to consolidate the related VIE if we are deemed to be the primary beneficiary. Deposits with land banking entities determined to be VIEs but not consolidated because we are not the primary beneficiary are at held at cost and included in escrow deposits, prepaid expenses and other assets within the consolidated balance sheets. As of December 31, 2022 and 2021, the carrying value of these deposits and the Company’s maximum exposure to loss was $14.5 million and zero, respectively.

We also consider whether the land option contracts should be accounted for as financing arrangements when the land banking entity is not consolidated under the variable interest model, as may be required if the land banking entity or other third-party acquires specific land parcels directly from us, on our behalf or at our direction or where we make improvements to the underlying land during the option period. During the year ended December 31, 2022, the Company entered into land option agreements whereby it sold land to a third party with an option to repurchase finished lots on a predetermined schedule. Because of our options to repurchase the finished lots, in accordance with ASC 606-10-55-70, we accounted for these transactions as financing arrangements rather than a sale. Consolidated land not owned is included in escrow deposits, prepaid expenses and other assets and the liability for consolidated land not owned, which represents proceeds received from the third party net of our deposits on the optioned land, is included in accounts payable and accrued expenses in the consolidated balance sheets (see Note 5. Escrow Deposits, Prepaid Expenses and Other Assets and Note 8. Accounts Payable and Accrued Expenses).

We lease commercial office space from third parties for use in our corporate and property management operations. Commercial office leases are accounted for as operating leases in accordance with ASC 842, Leases, which requires us to recognize right-of-use assets and lease liabilities within the consolidated balance sheets for the rights and obligations created from these leases. Operating lease right-of-use assets and lease liabilities are recognized based on the present value of future minimum lease payments over the expected lease term at commencement date. As the implicit rate is generally not determinable, the right-of-use assets and lease liabilities are measured using our incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments at commencement date. The expected lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise such options. Lease expense for operating leases is recognized on a straight-line basis over the expected lease term in general and administrative expense within the consolidated statements of operations.

Finite-lived intangible assets are amortized on a straight-line basis over their estimated economic lives. The Company reviews finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the sum of the estimated future cash flows expected to result from the use and eventual disposition of an asset is less than its net book value, an impairment loss is recognized. Measurement of an impairment loss is based on the fair value of an asset. No impairment was recorded during the years ended December 31, 2022, 2021 and 2020.

Goodwill represents the fair value in excess of the tangible and separately identifiable intangible assets that were acquired in connection with the internalization of the Company’s management function in June 2013, including all administrative, financial, property management, marketing and leasing personnel, including executive management. Goodwill has an indefinite life and is therefore not amortized. The Company analyzes goodwill for impairment on an annual basis pursuant to ASC 350, Intangibles—Goodwill and Other, which permits us to assess qualitative factors to determine whether it is more likely than not that the fair value of the reporting unit is less than the carrying amount as a basis to determine whether an impairment test is necessary. This qualitative assessment requires judgment to be applied in evaluating the effects of multiple factors, including macroeconomic conditions, industry and market conditions, cost factors, overall financial performance, other relevant entity-specific events, events affecting the reporting unit, and whether or not there has been a sustained decrease in the Company’s stock price. We also have the option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the goodwill impairment test. The impairment test compares the fair value of the reporting unit with its carrying amount. If the carrying amount exceeds the fair value, the impairment loss is determined as the excess of the carrying amount of the goodwill reporting unit over the fair value of that goodwill, not to exceed the carrying amount. Impairment charges, if any, are recognized in operating results. Based on our assessment of qualitative factors on December 31, 2022, we concluded it was more likely than not that the Company’s recorded goodwill balance of $120.3 million was not impaired and did not perform the quantitative test. No goodwill impairment was recorded during the years ended December 31, 2022, 2021 and 2020.

Financing costs related to the origination of the Company’s debt instruments are deferred and amortized as interest expense under the effective interest method over the contractual term of the applicable financing. Financing costs related to the origination of the Company’s revolving credit facility are presented net of accumulated amortization and included in escrow deposits, prepaid expenses and other assets within the consolidated balance sheets. Financing costs related to the origination of the Company’s unsecured senior notes and asset-backed securitizations are presented net of accumulated amortization and are netted against the related debt instrument under liabilities within the consolidated balance sheets.

We consider all demand deposits, cashier’s checks, money market accounts and certificates of deposit with a maturity of three months or less to be cash equivalents. We maintain our cash and cash equivalents and escrow deposits at financial institutions. The combined account balances typically exceed the Federal Deposit Insurance Corporation insurance coverage, and, as a result, there is a concentration of credit risk related to amounts on deposit. We believe that the risk is not significant.

Escrow deposits include refundable and non-refundable cash earnest money deposits for the purchase of properties and deposits related to land option contracts (see Land Option Contracts above). In addition, escrow deposits include amounts paid for single-family properties in certain states which require a judicial order when the risks and rewards of ownership of the property are transferred and the purchase is finalized.

Investments in unconsolidated joint ventures are recorded initially at cost, and subsequently adjusted for equity in earnings and cash contributions and distributions. Under the equity method of accounting, our net equity investment is included in investments in unconsolidated joint ventures within the consolidated balance sheets, and our share of net income or loss from the joint ventures is included within other income and expense, net in the consolidated statements of operations. Our recognition of joint venture income or loss is generally based on ownership percentages, which may change upon the achievement of certain investment return thresholds. The ultimate realization of the investment in unconsolidated joint ventures is dependent on a number of factors, including the performance of each investment and market conditions. We classify distributions received from our unconsolidated joint ventures using the “cumulative earnings” approach, under which distributions up to the amount of cumulative equity in earnings recognized will be classified as cash inflows from operating activities, and those in excess of that amount will be classified as cash inflows from investing activities in our consolidated statements of cash flows.

Our investments in unconsolidated joint ventures are reviewed for impairment periodically and we will record an impairment charge when events or circumstances change indicating that a decline in the fair values below the carrying values has occurred and such decline is other-than-temporary. During the year ended December 31, 2020, the Company recognized a $4.9 million impairment charge, of which $3.5 million was recognized in gain on sale and impairment of single-family properties and other, net and $1.4 million was recognized in other income and expense, net within the consolidated statements of operations, associated with the liquidation of legacy joint ventures, which were acquired as part of the American Residential Properties, Inc. (“ARPI”) merger in February 2016.

The Company obtained promissory notes in connection with two bulk dispositions of our single-family properties. The promissory note obtained during the second quarter of 2019 was paid in full during the year ended December 31, 2022 and the promissory note obtained during the first quarter of 2017 matured in the first quarter of 2022 and is still being actively collected. The promissory notes are secured by first priority mortgages on the disposed homes, contain certain covenants and require monthly or quarterly interest payments with the full principal due at maturity.

Notes receivable are presented net of discounts in escrow deposits, prepaid expenses and other assets within the consolidated balance sheets. Interest income from the notes, including amortization of discounts, is presented in other income and expense, net within the consolidated statements of operations. Upon adoption of Accounting Standards Update (“ASU”) 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, on January 1, 2020, we are required to estimate and recognize lifetime expected losses, rather than incurred losses, on these notes receivable, which results in the earlier recognition of credit losses even if the expected risk of credit loss is remote. Notes receivable are also presented net of the allowance for expected

credit losses, which the Company estimates on a quarterly basis based on (i) credit quality indicators such as the borrower’s historical performance, including the borrower’s financial results and satisfaction of scheduled payments, (ii) current conditions, including macroeconomic conditions and other conditions affecting the borrower, and (iii) other reasonable and supportable forecasts about the future. As part of the monitoring process, we may meet with a borrower’s management to better understand such borrower’s financial performance and its future plans on an as-needed basis. A note receivable will be categorized as non-performing if a borrower experiences financial difficulty and has failed to make scheduled payments. Changes to the allowance for expected credit losses are recognized in other income and expense, net within the consolidated statements of operations.

We lease single-family properties that we own directly to tenants who occupy the properties under operating leases, generally, with a term of one year. In accordance with ASC 842, Leases, the Company classifies our single-family property leases as operating leases and elects to not separate the lease component, comprised of rents from single-family properties, from the associated non-lease component, comprised of fees from single-family properties and tenant charge-backs. The combined component is accounted for under ASC 842, while certain tenant charge-backs are accounted for as variable payments under ASC 606, Revenue from Contracts with Customers. Rental revenue, net of any concessions, is recognized on a straight-line basis over the term of the lease, which is not materially different than if it were recorded when due from tenants and recognized monthly as it is earned. Tenant charge-backs, which are primarily related to cost recoveries on utilities, are recognized as revenue on a gross basis in the period during which the expenses are incurred.

Gains or losses on sales of properties and upon contributions to our unconsolidated joint ventures are recognized pursuant to the provisions included in ASC 610-20, Other Income. Under ASC 610-20, we must first determine whether the transaction is a sale to a customer or non-customer. We typically sell properties on a selective basis and not within the ordinary course of our operating business and therefore expect that our sale transactions will not be contracts with customers. We next determine whether we have a controlling financial interest in the property after the sale, consistent with the consolidation model in ASC 810, Consolidation. If we determine that we do not have a controlling financial interest in the real estate, we evaluate whether a contract exists under ASC 606 and whether the buyer has obtained control of the asset that was sold. We recognize a full gain or loss on sale, which is presented in gain on sale and impairment of single-family properties and other, net within the consolidated statements of operations, when the derecognition criteria under ASC 610-20 have been met.

Accounts payable and accrued expenses consists primarily of trade payables, accrued interest, distribution payables, resident security deposits, prepaid rent, construction and maintenance liabilities, HOA fees, operating lease liabilities and property tax accruals as of the end of the respective period presented. It also consists of liabilities for consolidated land not owned (see Land Option Contracts above) and contingent loss accruals, if any, when such losses are both probable and estimable. When it is reasonably possible that a significant contingent loss has occurred, we disclose the nature of the potential loss and, if estimable, a range of exposure.

Our 2012 Equity Incentive Plan and 2021 Equity Incentive Plan (collectively, the “Plans”) are accounted for under the provisions of ASC 718, Compensation—Stock Compensation. Noncash share-based compensation costs related to options to purchase our Class A common shares, restricted share units (“RSUs”) and performance-based restricted share units (“PSUs”) issued to members of the Company’s board of trustees and employees is based on the fair value of the options, RSUs and PSUs on the grant date and generally amortized over the service period. At the time of grant, the Company takes into consideration the timing of the equity award and evaluates for conditions that could result in the award to be considered spring-loaded, in which case the fair value would be adjusted.

The Plans allow for continued release of awards based on the original vesting schedule, rather than forfeiture, of unvested share-based grants upon termination of service for employees who meet certain retirement eligibility criteria, including age and years of service. Retirement eligible employees must also provide a notice of intent to retire at least six months prior to retirement date and the Human Capital and Compensation Committee (“HCC Committee”) must approve the continued release of awards. As a result of the six month notice requirement, compensation cost is recognized over six months from the grant date to the extent an employee is retirement eligible on the grant date and compensation cost is accelerated to the extent that an employee will become retirement eligible before six months prior to the end of the contractual life of their share-based grants.

The fair value of a financial instrument is the amount at which the instrument could be exchanged in an orderly transaction between two willing parties. Fair value is a market-based measurement, and should be determined based on the assumptions that market participants would use in pricing an asset or liability. The GAAP valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The three levels are defined as follows:

From time to time, we may use interest rate cap agreements or other derivative instruments for interest rate risk management purposes. We assess these derivatives at inception and on an ongoing basis for the effectiveness of qualifying cash flow hedges. For derivative instruments that are designated and qualify as a cash flow hedge, the gain or loss on the derivative instrument is reported as a component of other comprehensive income and reclassified into earnings as interest expense during the period in which the hedged transaction affects earnings.

During the year ended December 31, 2022, the Company reassessed its operating segments as a result of changes in information presented to its chief operating decision maker (“CODM”). We operate in one operating segment with activities related to acquiring, renovating, developing, leasing and managing single-family homes as rental properties. ASC 280, Segment Reporting, requires the use of the “management approach” to align segment reporting with our internal reporting, and our CODM regularly reviews core funds from operations at the total portfolio level as the primary measure for assessing the Company’s performance and allocating resources. Property acquisition and disposition decisions are made at the individual property level and development decisions are made at the community level across a geographically diversified portfolio based on criteria consistent with our objective of generating attractive risk-adjusted returns for our shareholders.
