Organization and Basis of Presentation	1. Organization and Basis of Presentation The information contained in the following notes to the consolidated financial statements is condensed from that which would appear in the annual consolidated financial statements; accordingly, the consolidated financial statements included herein should be reviewed in conjunction with the consolidated financial statements for the fiscal year ended December 31, 2021, and related notes thereto, included in the Annual Report on Form 10-K of Easterly Government Properties, Inc. (the “Company”) for the year ended December 31, 2021 filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 28, 2022. The Company is a Maryland corporation that has elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”), commencing with its taxable year ended December 31, 2015. The operations of the Company are carried on primarily through Easterly Government Properties LP (the “Operating Partnership”) and the wholly owned subsidiaries of the Operating Partnership. As used herein, the “Company refer to Easterly Government Properties, Inc. and its consolidated subsidiaries and partnerships, including the Operating Partnership, except where context otherwise requires. We are an internally managed REIT, focused primarily on the acquisition, development, and management of Class A commercial properties that are leased to U.S. Government agencies that serve essential functions. We generate substantially all of our revenue by leasing our properties to such agencies, either directly or through the U.S. General Services Administration (“GSA”). Our objective is to generate attractive risk-adjusted returns for our stockholders over the long-term through dividends and capital appreciation. We focus on acquiring, developing and managing U.S. Government leased properties that are essential to supporting the mission of the tenant agency and strive to be a partner of choice for the U.S. Government, working closely with the tenant agency to meet its needs and objectives. As of March 31, 2022, we wholly owned 85 operating properties and four operating properties through an unconsolidated joint venture (the “JV”) in the United States, encompassing approximately 8.6 million leased square feet, including 88 operating properties that were leased primarily to U.S. Government tenant agencies and one operating property that was entirely leased to a private tenant. As of March 31, 2022, our operating properties were 99% leased. For purposes of calculating percentage leased, we exclude from the denominator total square feet that was unleased and to which we attributed no value at the time of acquisition. In addition, we wholly owned one property under development that we expect will encompass approximately 0.2 million leased square feet upon completion. The Operating Partnership holds substantially all of our assets and conducts substantially all of our business. We are the sole general partner of the Operating Partnership. We owned approximately 89.0% of the aggregate limited partnership interests in the Operating Partnership (“common units”) at March 31, 2022. We believe that we have operated and have been organized in conformity with the requirements for qualification and taxation as a REIT for U.S. federal income tax purposes commencing with our taxable year ended December 31, 2015. Principles of Consolidation The accompanying consolidated financial statements are presented on the accrual basis of accounting in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include the accounts of the Company, Easterly Government Properties TRS, LLC, Easterly Government Services, LLC, the Operating Partnership and its other subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. Basis of Presentation The condensed consolidated financial statements included herein are unaudited; however, they include all adjustments (consisting only of normal recurring adjustments) which, in the opinion of management, are necessary to state fairly the consolidated financial position of the Company at March 31, 2022 and December 31, 2021, the consolidated results of operations for the three months ended March 31, 2022 and 2021, and the consolidated cash flows for the three months ended March 31, 2022 and 2021. The year-end condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by GAAP. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for the full year. The preparation of the consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the date of the balance sheet, and the reported amounts of revenues and expenses during the reporting period. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, including the impact of extraordinary events such as the novel coronavirus (COVID-19) pandemic, the results of which form the basis for making judgements about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or condition s .

Fair Value Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	7. Fair Value Measurements Accounting standards define fair value as the exit price, or the amount that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The standards also establish a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability developed based on market data obtained from sources independent of us. Unobservable inputs are inputs that reflect our assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances. The hierarchy of these inputs is broken down into three levels: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. Categorization within the valuation hierarchy is based upon the lowest level of input that is most significant to the fair value measurement. Recurring fair value measurements The fair values of our interest rate swaps are determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities in such interest rates. While the Company determined that the majority of the inputs used to value its derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. The Company has determined that the significance of the impact of the credit valuation adjustments made to its derivative contracts, which determination was based on the fair value of each individual contract, was not significant to the overall valuation. As a result, all of the Company’s derivatives held as of March 31, 2022 were classified as Level 2 of the fair value hierarchy. The carrying values of cash and cash equivalents, restricted cash, accounts receivable, other assets and accounts payable and accrued expenses are reasonable estimates of fair values because of the short maturities of these instruments. The table below presents the Company’s assets and liabilities measured at fair value on a recurring basis as of March 31, 2022, aggregated by the level in the fair value hierarchy within which those measurements fall (amounts in thousands): As of March 31, 2022 Balance Sheet Line Item Level 1 Level 2 Level 3 Interest rate swaps - Asset $ — $ 1,136 $ — Interest rate swaps - Liability $ — $ (1,330 ) $ — For our disclosure of debt fair values, we estimated the fair value of our 2016 term loan facility and our 2018 term loan facility based on the variable interest rate and credit spreads (categorized within Level 3 of the fair value hierarchy) and estimated the fair value of our other debt based on the discounted estimated future cash payments to be made on such debt (categorized within Level 3 of the fair value hierarchy); the discount rates used approximate current market rates for loans, or groups of loans, with similar maturities and credit quality, and the estimated future payments included scheduled principal and interest payments. Fair value estimates are made as of a specific point in time, are subjective in nature and involve uncertainties and matters of significant judgment. Settlement at such fair value amounts may not be possible and may not be a prudent management decision. Financial assets and liabilities not measured at fair value As of March 31, 2022, all financial instruments and liabilities were reflected in our balance sheets at amounts which, in our estimation, reasonably approximated their fair values, except for the following: As of March 31, 2022 Financial liabilities Carrying Amount (1) Fair Value (2) Revolving credit facility $ 35,000 $ 35,000 2016 term loan facility $ 100,000 $ 100,000 2018 term loan facility $ 150,000 $ 150,000 Notes payable $ 700,000 $ 690,623 Mortgages payable $ 250,158 $ 250,363 (1) The carrying amount consists of principal only. (2) We deem the fair value measurement of the financial liability instrument a Level 3 measurement.

Equity [Abstract]
Equity Incentive Plan	8. Equity Incentive Plan Restricted Shares The Company awards restricted stock to certain members of management and non‑employee directors. Management awards generally vest over a range of two to four years. Non‑employee director shares vest upon the earlier of the anniversary of the date of the grant or the next annual stockholder meeting, as long as the grantee remains a director or employee on such date. Restricted stock awards issued under the 2015 Equity Incentive Plan, as amended (the “2015 Equity Incentive Plan”) may not be sold or otherwise transferred until restrictions have lapsed, as established by the compensation committee. We value our non-vested restricted share awards at the grant date fair value, which was the market price of our common stock as of the applicable grant date. We recognized $0.2 million in compensation expense related to restricted common stock awards for each of the three months ended March 31, 2022 and 2021. The fair value of restricted stock that vested was $1.1 million and $0.4 million during the three months ended March 31, 2022 and 2021, respectively based on the market price at the vesting date. The balance of unamortized restricted stock expense as of March 31, 2022, was $0.4 million, which is expected to be recognized over a weighted‑average period of 1.7 years. A summary of the status of our restricted shares as of March 31, 2022 and changes during the three months ended March 31, 2022 is presented below: Restricted Shares Restricted Shares Weighted Average Grant Date Fair Value Per Share Outstanding, December 31, 2021 86,006 $ 19.16 Vested (48,408 ) 17.69 Granted 7,353 20.68 Forfeited — — Outstanding, March 31, 2022 44,951 $ 21.00 LTIP Units The Company grants LTIP units to certain members of management and non‑employee directors. Management awards generally vest immediately or over a range of two to four years. Non‑employee director shares vest upon the earlier of the anniversary of the date of the grant or the next annual stockholder meeting, as long as the grantee remains a director or employee on such date. Performance-based LTIP units are earned subject to the Company achieving certain thresholds, including absolute total shareholder returns, relative total shareholder returns, or operational hurdles through the performance period. Service-based LTIP units are earned over time, subject to continued employment and other terms of the awards. The following is a summary of our granted LTIP unit awards during the three months ended March 31, 2022: Award Type Grant Date Performance Period End Date Vest Date Units Granted Service January 3, 2022 December 31, 2024 December 31, 2024 110,906 Operational January 3, 2022 December 31, 2024 1 80,160 Performance January 3, 2022 December 31, 2024 1 158,535 2022 LTIP Grant 349,601 (1) Earned units will vest on date of compensation committee determination of performance. We value our operational LTIP unit awards that are subject to the Company achieving certain performance conditions at the grant date fair value, which is the market price of our common stock as of the applicable grant date. We value our service-based LTIP unit awards at the grant date fair value, which is the market price of our common stock as of the applicable grant date, discounted by the risk related to the timing of book-up events. For the performance LTIP unit awards granted that are subject to the Company achieving certain total shareholder return thresholds, we used a Monte Carlo Simulation (risk-neutral approach) to determine the grant date fair value. The following is a summary of the significant assumptions used to value the total shareholder return performance-based LTIP units during the three months ended March 31, 2022: Expected volatility 27.0 % Dividend yield 4.8 % Risk-free interest rate 1.0 % Expected life 3 years The fair value of LTIP units that vested were $5.3 million and $4.5 million during the three months ended March 31, 2022 and 2021, respectively, based on the market price at the vesting date. We recognized $1.4 million and $1.1 million in compensation expense related to LTIP unit awards for the three months ended March 31, 2022 and 2021, respectively. The balance of unamortized LTIP expense as of March 31, 2022 was $10.7 million, which is expected to be recognized over a weighted‑average period of 2.2 years. As of March 31, 2022, management considers it probable that the operational performance conditions on our unvested grants will be achieved. A summary of the status of our LTIP units as of March 31, 2022 and changes during the three months ended March 31, 2022 are presented below: LTIP Units (1) LTIP Units Weighted Average Grant Date Fair Value Per Share Outstanding, December 31, 2021 651,238 $ 21.02 Vested (108,765 ) 18.75 Granted 349,601 17.53 Forfeited — — Outstanding, March 31, 2022 892,074 $ 19.93 (1) Reflects the number of LTIP units issued to the grantee on the date which may be different from the number of LTIP units actually earned in the case of performance-based LTIP units.

After the end of the performance period, the number of LTIP units, both vested and unvested, that LTIP award recipients have earned, if any, are entitled to receive dividends in an amount per LTIP unit equal to dividends, both regular and special, payable per common unit. Holders of LTIP units that are not subject to the attainment of performance goals are entitled to receive dividends per LTIP unit equal to 100% of the dividend paid per common unit beginning on the grant date. Offering of Common Stock on a Forward Basis On August 11, 2021, the Company and the Operating Partnership completed an underwritten public offering of 6,300,000 shares of common stock offered on a forward basis. In connection with the offering, the Company also entered into separate forward sale agreements with each of the forward purchasers (the “Forward Sales Agreements”), pursuant to which the forward purchasers borrowed and sold to the underwriters an aggregate of 6,300,000 shares of the Company’s common stock. On December 28, 2021, the Company issued 3,991,000 shares of its common stock for net proceeds of $85.0 million, which shares were issued in partial settlement of the Forward Sales Agreements entered into in connection with the underwritten public offering. No shares were issued during the three months ended March 31, 2022. The Company expects to physically settle the remaining Forward Sales Agreements and receive proceeds, subject to certain adjustments, from the sale of those shares of common stock upon one or more such physical settlements within approximately one year from the date of the offering. Although the Company expects to settle the Forward Sales Agreements entirely by the physical delivery of shares of its common stock for cash proceeds, the Company may also elect to cash or net-share settle all or a portion of its obligations under the Forward Sales Agreements, in which case, the Company may receive, or may owe, cash or shares of its common stock from or to the forward purchasers. The Forward Sales Agreements provide for an initial forward price of $21.64 per share, subject to certain adjustments pursuant to the terms of each of the Forward Sales Agreements. The Forward Sales Agreements are subject to early termination or settlement under certain circumstances. ATM Programs The Company entered into separate equity distribution agreements on each of December 20, 2019 (the “2019 ATM Program”) and June 22, 2021 (the “2021 ATM Program” and, together with the 2019 ATM Program, the “ATM Programs”) with various financial institutions pursuant to which it may issue and sell shares of its common stock having an aggregate offering price of up to $300.0 million under each ATM Program from time to time in negotiated transactions or transactions that are deemed to be “at the market” offerings as defined in Rule 415 under the Securities Act. Under each of the ATM Programs, the Company may enter into one or more forward transactions (each, a “forward sale transaction”) under separate master forward sale confirmations and related supplemental confirmations with each of the various financial institutions party to the respective ATM Program for the sale of shares of its common stock on a forward basis. The following table sets forth certain information with respect to issuances under the 2019 ATM Program during the quarter ended March 31, 2022 (amounts in thousands except share amounts): 2019 ATM Program For the Three Months Ended: Number of Shares Issued (1) Net Proceeds (1) March 31, 2022 434,925 $ 9,409 Total 434,925 $ 9,409 (1) Shares issued by the Company, which were all issued in settlement of forward sales transactions. Additionally, as of March 31, 2022, the Company had entered into forward sales transactions under the 2019 ATM Program for the sale of an additional 1,950,000 shares of its common stock that have not yet been settled. Subject to its right to elect net share settlement, the Company expects to physically settle the forward sales transactions by the maturity dates set forth in each applicable forward sale transaction placement notice, which dates range from June 2022 to January 2023. Assuming the forward sales transactions are physically settled in full utilizing a net weighted average initial forward sales price of $21.82 per share, the Company expects to receive net proceeds of approximately $42.6 million, after deducting offering costs, subject to adjustments in accordance with the applicable forward sale transaction. The Company accounted for the forward sale agreements as equity. No sales of shares of the Company’s common stock were made under the 2021 ATM Program during the quarter ended March 31, 2022. The Company used the net proceeds received from such sales for general corporate purposes. As of March 31, 2022, the Company had approximately $300.0 million of gross sales of its common stock available under the 2021 ATM Program and $87.4 million of gross sales of its common stock available under the 2019 ATM Program.

Earnings Per Share [Abstract]
Earnings Per Share	10. Earnings Per Share Basic earnings or loss per share of common stock (“EPS”) is calculated by dividing net income attributable to common stockholders by the weighted average shares of common stock outstanding for the periods presented. Diluted EPS is computed after adjusting the basic EPS computation for the effect of dilutive common equivalent shares outstanding during the periods presented. Unvested restricted shares of common stock and unvested LTIP units are considered participating securities, which require the use of the two-class method for the computation of basic and diluted earnings per share. The following table sets forth the computation of the Company’s basic and diluted earnings per share of common stock for the three months ended March 31, 2022 and 2021 (amounts in thousands, except per share amounts): For the three months ended March 31, 2022 2021 Numerator Net income $ 8,263 $ 7,880 Less: Non-controlling interest in Operating Partnership (922 ) (889 ) Net income available to Easterly Government Properties, Inc. 7,341 6,991 Less: Dividends on participating securities (135 ) (114 ) Net income available to common stockholders $ 7,206 $ 6,877 Denominator for basic EPS 90,150,518 82,120,353 Dilutive effect of share-based compensation awards 36,929 55,822 Dilutive effect of LTIP units (1) 304,861 411,434 Dilutive effect of shares issuable under forward sale agreements (2) 79,263 8,988 Denominator for diluted EPS 90,571,571 82,596,597 Basic EPS $ 0.08 $ 0.08 Diluted EPS $ 0.08 $ 0.08 (1) (2)

Leases [Abstract]
Leases	11. Leases Lessor The Company leases commercial space to the U.S. Government through the GSA or other federal agencies or nongovernmental tenants. These leases may contain extension options that are predominately at the sole discretion of the tenant. Certain of our leases contain a “soft-term” period of the lease, meaning that the U.S. Government tenant agency has the right to terminate the lease prior to its stated lease end date. While certain of our leases are contractually subject to early termination, we do not believe that our tenant agencies are likely to terminate these leases early given the build-to-suit features at the properties subject to the leases, the weighted average age of these properties based on the date the property was built or renovated-to-suit, where applicable (approximately 17.4 years properties. Certain lease agreements include variable lease payments that, in the future, will vary based on changes in inflationary measures, real estate tax rates, usage, or share of expenditures of the leased premises . The following table summarizes the maturity of fixed lease payments under the Company’s leases as of March 31, 2022 (amounts in thousands): Payments due by period Total 2022 (1) 2023 2024 2025 2026 Thereafter Fixed lease payments $ 1,996,172 169,737 213,084 195,681 183,142 174,013 1,060,515 (1) The table below sets forth our composition of lease revenue recognized between fixed and variable components (amounts in thousands): For the three months ended March 31, 2022 2021 Fixed $ 65,447 $ 59,640 Variable 4,992 4,539 Property rental revenue 70,439 64,179 Lessee The Company leases corporate office space under operating lease arrangements in Washington, D.C. and San Diego, CA. The San Diego, CA operating lease is set to expire in March 2023 with the option to terminate in October 2022. The option to terminate was included in the term used in determining the right-of-use asset balance. The leases include variable lease payments that, in the future, will vary based on changes in real estate tax rates, usage, or share of expenditures of the leased premises. The Company has elected not to separate lease and non-lease components for its corporate office leases. As of March 31, 2022 and December 31, 2022, the unamortized balances associated with the Company’s right-of-use operating lease asset and operating lease liability were $1.5 million and $1.6 million, respectively. The Company used its incremental borrowing rate, which was arrived at utilizing prevailing market rates and the spread on its revolving credit facility, in order to determine the net present value of the minimum lease payments. The following table provides quantitative information for the Company’s commenced operating leases for the three months ended March 31, 2022 and 2021 (amounts in thousands): For the three months ended March 31, 2022 2021 Cash flows from operating lease costs $ 101 $ 149 In addition, the maturity of fixed lease payments under the Company’s commenced corporate office leases as of March 31, 2022 is summarized in the table below (amounts in thousands): Corporate office leases Payments due by period 2022 (1) 277 2023 277 2024 446 2025 456 2026 309 Thereafter — Total future minimum lease payments $ 1,765 Imputed interest (128 ) Total $ 1,637 (1) Represents the nine months ended December 31, 2022.

The duration of the majority of tenant construction project reimbursement arrangements are less than a year and payment is typically due once a project is complete and work has been accepted by the tenant. There were no projects on-going as of March 31, 2022 with a duration of greater than one year. During each of the three months ended March 31, 2022 and 2021, the Company recognized $0.1 million in parking garage income generated from the operations of parking garages situated on the Various GSA – Buffalo property and on the Various GSA – Portland property. The monthly and transient daily parking revenue falls within the scope of Revenue from Contracts with Customers (“ASC 606”) and is accounted for at the point in time when control of the goods or services transfers to the customer and the Company’s performance obligation is satisfied. The balance in Accounts receivable related to parking garage income was less than $0.1 million as of each of March 31, 2022 and December 31, 2021. During the three months ended March 31, 2022 and 2021, the Company recognized $0.1 million and $0.3 million, respectively, in income for providing COVID-19 related cleaning services to certain tenants. The income falls within the scope of ASC 606 and is recognized over time as the performance obligation is satisfied. The balance in Accounts receivable related to these services was less than $0.1 million as of March 31, 2022, and $0.1 million as of December 31, 2021. There were no contract assets or liabilities as of March 31, 2022 or December 31, 2021.

Risks And Uncertainties [Abstract]
Concentrations Risk	13. Concentrations Risk Concentrations of credit risk arise for the Company when multiple tenants of the Company are engaged in similar business activities, are located in the same geographic region or have similar economic features that impact in a similar manner their ability to meet contractual obligations, including those to the Company. The Company regularly monitors its tenant base to assess potential concentrations of credit risk. As stated in Note 1 above, the Company leases commercial space to the U.S. Government or non-governmental tenants. At March 31, 2022, the U.S. Government accounted for approximately 97.6% of our total annualized lease income and non-governmental tenants accounted for the remaining approximately 2.4%. Seventeen of our 89 wholly-owned and unconsolidated operating properties are located in California, accounting for approximately 15.5% of our total leased square feet and approximately 21.0% of our total annualized lease income as of March 31, 2022. To the extent that weak economic or real estate conditions or natural disasters affect California more severely than other areas of the country, our business, financial condition and results of operations could be significantly impacted.
