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, 2022, 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, 2022 filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 28, 2023. 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,” “we,” “us,” or “our” 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 September 30, 2023, we wholly owned 78 operating properties and nine operating properties through an unconsolidated joint venture (the “JV”) in the United States, encompassing approximately 8.6 million leased square feet, including 86 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 September 30, 2023, our operating properties were 97 % 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 88.5 % of the aggregate limited partnership interests in the Operating Partnership (“common units”) at September 30, 2023. 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 September 30, 2023 and December 31, 2022, the consolidated results of operations for the three and nine months ended September 30, 2023 and 2022, and the consolidated cash flows for the nine months ended September 30, 2023 and 2022. 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, the results of which form the basis for making judgments 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 conditions.

On February 3, 2023, we entered into three SOFR-based interest rate swaps each with a notional value of $ 100.0 million that were designated as cash flow hedges of interest rate risk. Two of the interest rate swaps, with an aggregate notional value of $ 200.0 million, became effective in June 2023 . The third swap, with a notional value of $100.0 million, became effective in September 2023. See Note 6 for more information on our interest rate swaps. On May 30, 2023, we entered into the third amendment to our second amended and restated credit agreement, dated as of July 23, 2021 and into the sixth amendment to our senior unsecured term loan agreement, dated as of September 29, 2016. These amendments added a daily simple SOFR-based option to the term SOFR-based floating interest rate option as a benchmark rate for borrowings denominated in U.S. dollars for all purposes under the credit and term loan agreements, including, in each case, a credit spread adjustment of 0.10 %. On July 20, 2023, we exercised in full the $ 50.0 million delayed draw option on our 2018 term loan facility, increasing our 2018 term loan facility commitments from $ 150.0 million to $ 200.0 million, and transferred $ 50.0 million of our interest rate swap with a notional value of $ 100.0 million, from our revolving credit facility to the $ 50.0 million delayed draw. Financial Covenant Considerations As of September 30, 2023, we were in compliance with all financial and other covenants related to our debt.

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 we determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by us and our counterparties. We have determined that the significance of the impact of the credit valuation adjustments made to our 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 our derivatives held as of September 30, 2023 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 our assets measured at fair value on a recurring basis as of September 30, 2023, aggregated by the level in the fair value hierarchy within which those measurements fall (amounts in thousands): As of September 30, 2023 Balance Sheet Line Item Level 1 Level 2 Level 3 Interest rate swaps $ — $ 5,003 $ — 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 September 30, 2023, 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 September 30, 2023 Financial liabilities Carrying Amount (1) Fair Value (2) Revolving credit facility $ — $ — 2016 term loan facility $ 100,000 $ 100,000 2018 term loan facility $ 200,000 $ 200,000 Notes payable $ 700,000 $ 570,336 Mortgages payable $ 221,686 $ 204,129 (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 Incentive Plan	8. Equity Incentive Plan Restricted Shares We award 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 awards vest upon the earlier of the anniversary of the date of the grant or the next annual stockholder meeting, subject to the grantee's continued service with the Company through 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. Compensation expense related to restricted common stock awards was $ 0.1 million for both the three months ended September 30, 2023 and 2022 and $ 0.4 million and $ 0.5 million for the nine months ended September 30, 2023 and 2022, respectively. The fair value of restricted stock that vested was $ 0.4 million and $ 1.5 million during the nine months ended September 30, 2023 and 2022, respectively, based on the market price at the vesting date. The balance of unamortized restricted stock expense as of September 30, 2023 was $ 0.4 million, which is expected to be recognized over a weighted average period of 0.9 years. A summary of the status of our restricted shares as of September 30, 2023 and changes during the nine months ended September 30, 2023 is presented below: Restricted Shares Restricted Shares Weighted Average Grant Date Outstanding, December 31, 2022 41,315 $ 19.94 Vested ( 30,987 ) 19.43 Granted 32,486 14.18 Forfeited — — Outstanding, September 30, 2023 42,814 $ 15.94 LTIP Units We grant 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 awards vest upon the earlier of the anniversary of the date of the grant or the next annual stockholder meeting, subject to the grantee's continued service with the Company through such date. Performance-based LTIP units are earned subject to us achieving certain thresholds, including absolute total shareholder returns, relative total shareholder returns, or operational hurdles through the performance period. Service-based LTIP units vest 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 nine months ended September 30, 2023: Award Grant Performance Period Vest Date Units Granted Service January 3, 2023 — December 31, 2025 219,859 Operational January 3, 2023 December 31, 2025 1 127,291 Performance January 3, 2023 December 31, 2025 1 148,633 Service March 2, 2023 — March 2, 2026 3,438 Service May 9, 2023 — 2 16,244 2023 LTIP Grant 515,465 (1) Earned units will vest on the date of compensation committee determination of performance. (2) Units will vest on the earlier of the anniversary of the grant date or the 2024 stockholder meeting. We value our operational LTIP unit awards that are subject to us 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 us 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 for performance-based LTIP units during the nine months ended September 30, 2023: Expected volatility 29.0 % Dividend yield 5.6 % Risk-free interest rate 4.2 % Expected life 3 years The fair value of LTIP units that vested were $ 4.0 million and $ 5.5 million during the nine months ended September 30, 2023 and 2022 , respectively, based on the market price at the vesting date. Compensation expense related to LTIP unit awards was $ 1.5 million and $ 1.5 million for the three months ended September 30, 2023 and 2022 , respectively, and $ 4.2 million and $ 4.4 million for the nine months ended September 30, 2023 and 2022, respectively. The balance of unamortized LTIP expense as of September 30, 2023 was $ 8.3 million, which is expected to be recognized over a weighted average period of 1.7 years. As of September 30, 2023, management considers it probable that the operational performance conditions on four of our five unvested grants will be achieved. A summary of the status of our LTIP units as of September 30, 2023 and changes during the nine months ended September 30, 2023 are presented below: LTIP Units (1) LTIP Units Weighted Average Grant Date Fair Value Per Share Outstanding, December 31, 2022 896,665 $ 19.90 Vested ( 204,570 ) 21.50 Granted 515,465 12.25 Forfeited ( 85,352 ) 18.30 Outstanding, September 30, 2023 1,122,208 $ 16.21 (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, we completed an underwritten public offering of 6,300,000 shares of common stock offered on a forward basis. In connection with the offering, we 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 our common stock. On December 28, 2021, we issued 3,991,000 shares of our 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. During the three months ended March 31, 2023, we issued 2,309,000 shares of common stock under the Forward Sale Agreements and received net cash proceeds of approximately $ 46.8 million. As of September 30, 2023, all shares of common stock under the Forward Sales Agreements had been issued and settled. ATM Programs We 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 we may issue and sell shares of our 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 of 1933, as amended (the “Securities Act”). Under each of the ATM Programs, we 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 our common stock on a forward basis. The following table sets forth certain information with respect to issuances under the 2019 ATM Program during the nine months ended September 30, 2023 (amounts in thousands except share amounts): 2019 ATM Program For the three months ended Number of Shares Issued (1) Net Proceeds (1) March 31, 2023 250,000 $ 5,562 June 30, 2023 — — September 30, 2023 1,700,000 33,717 Total 1,950,000 $ 39,279 (1) Shares were all issued in settlement of forward sales transactions. As of September 30, 2023 , we had settled all of our outstanding forward sales transactions under the 2019 ATM Program. We accounted for the forward sale transactions as equity. No sales of shares of our common stock were made under the 2021 ATM Program during the nine months ended September 30, 2023. We used the net proceeds received from sales under our 2019 ATM Program for general corporate purposes. As of September 30, 2023, we had approximately $ 300.0 million of gross sales of our common stock available under the 2021 ATM Program and $ 87.4 million of gross sales of common stock available under the 2019 ATM Program. Share Repurchase Program On April 28, 2022, our Board of Directors authorized a share repurchase program whereby we may repurchase up to 4,538,994 shares of our common stock, or approximately 5 % of our outstanding shares as of the authorization date. We are not required to purchase shares under the share repurchase program, but may choose to do so in the open market or through privately negotiated transactions at times and amounts based on our evaluation of market conditions and other factors. No repurchases of shares of our common stock were made under the share repurchase program during the nine months ended September 30, 2023. Contribution of Property for Common Units On January 25, 2023, the Operating Partnership issued 12,391 common units and fully settled a contingent earn-out liability in connection with our acquisition of FBI / DEA - El Paso on May 26, 2020. The issuance of the common units was effected in reliance upon an exemption from registration provided by Section 4(a)(2) under the Securities Act.

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 our basic and diluted earnings per share of common stock for the three and nine months ended September 30, 2023 and 2022 (amounts in thousands, except per share amounts): For the three months ended September 30, For the nine months ended September 30, 2023 2022 2023 2022 Numerator Net income $ 6,081 $ 749 $ 16,273 $ 17,142 Less: Non-controlling interest in Operating Partnership ( 707 ) ( 107 ) ( 1,905 ) ( 1,962 ) Net income available to Easterly Government Properties, Inc. 5,374 642 14,368 15,180 Less: Dividends on participating securities ( 151 ) ( 137 ) ( 450 ) ( 410 ) Net income available to common stockholders $ 5,223 $ 505 $ 13,918 $ 14,770 Denominator for basic EPS 93,537,121 90,772,706 92,674,039 90,560,471 Dilutive effect of share-based compensation awards 14,363 11,455 18,483 20,646 Dilutive effect of LTIP units (1) 297,960 335,211 245,699 304,991 Dilutive effect of shares issuable under forward sale agreements (2) — — — — Denominator for diluted EPS 93,849,444 91,119,372 92,938,221 90,886,108 Basic EPS $ 0.06 $ 0.01 $ 0.15 $ 0.16 Diluted EPS $ 0.06 $ 0.01 $ 0.15 $ 0.16 (1) During both the three and nine months ended September 30, 2023 , there were 387,010 unvested performance-based LTIP units that were not included in the computation of diluted EPS because to do so would have been antidilutive for the period. During both the three and nine months ended September 30, 2022 , there were 314,529 unvested performance-based LTIP units that were not included in the computation of diluted EPS because to do so would have been antidilutive for the period. (2) During both the three and nine months ended September 30, 2023 , there were no shares of underlying unsettled forward sales transactions. During both the three and nine months ended September 30, 2022 , there were 4,259,000 shares of underlying unsettled forward sales transactions that were not included in the computation of diluted EPS because to do so would have been antidilutive for the period.

Leases [Abstract]
Leases	11. Leases Lessor We lease 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 19.3 years as of September 30, 2023), the mission-critical focus of the properties subject to the leases and the current level of operations at such 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.

Risks and Uncertainties [Abstract]
Concentrations Risk	13. Concentrations Risk Concentrations of credit risk arise for us when multiple of our tenants 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 obligations owed to us. We regularly monitor our tenant base to assess potential concentrations of credit risk. As stated in Note 1 above, we lease commercial space to the U.S. Government or non-governmental tenants. At September 30, 2023 , the U.S. Government accounted for approximately 98.5 % of our total annualized lease income and non-governmental tenants accounted for the remaining approximately 1.5 %. Seventeen of our 87 wholly-owned and unconsolidated operating properties are located in California, accounting for approximately 14.9 % of our total leased square feet and approximately 19.8 % of our total annualized lease income as of September 30, 2023 . 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.

Effective interest rates are as follows: VA – Golden 5.03 %, USFS II – Albuquerque 3.92 %, ICE – Charleston 3.93 %, VA – Loma Linda 3.78 %, CBP – Savannah 4.12 %, USCIS – Kansas City 2.05 %. Entered into one interest rate swap with an effective date of September 29, 2023 with a notional value of $ 100.0 million to effectively fix the interest rate at 5.05 % annually, based on our consolidated leverage ratio, as defined in our 2016 term loan facility agreement.
