Forward-Looking Statements

We make statements in this Supplemental Information Package that are considered “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act, which are usually identified by the use of words such as “anticipates,” “believes,” “estimates,” “expects,” “intends,” “may,” “plans,” “projects,” “seeks,” “should,” “will,” and variations of such words or similar expressions. We intend these forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 and are including this statement in this Supplemental Information Package for purposes of complying with those safe harbor provisions. These forward-looking statements reflect our current views about our plans, intentions, expectations, strategies and prospects, which are based on the information currently available to us and on assumptions we have made. Although we believe that our plans, intentions, expectations, strategies and prospects as reflected in or suggested by those forward-looking statements are reasonable, we can give no assurance that the plans, intentions, expectations or strategies will be attained or achieved. Furthermore, actual results may differ materially from those described in the forward-looking statements and will be affected by a variety of risks and factors that are beyond our control including, without limitation: risks associated with our dependence on the U.S. Government and its agencies for substantially all of our revenues, including credit risk and risk that the U.S. Government reduces its spending on real estate or that it changes its preference away from leased properties, including as a result of or in connection with any shutdown of the U.S. Government; risks associated with ownership and development of real estate; the risk of decreased rental rates or increased vacancy rates; the loss of key personnel; general volatility of the capital and credit markets and the market price of our common stock; the risk we may lose one or more major tenants; difficulties in completing and successfully integrating acquisitions; failure of acquisitions or development projects to occur at anticipated levels or yield anticipated results; risks associated with our joint venture activities; risks associated with actual or threatened terrorist attacks; intense competition in the real estate market that may limit our ability to attract or retain tenants or re-lease space; insufficient amounts of insurance or exposure to events that are either uninsured or underinsured; uncertainties and risks related to adverse weather conditions, natural disasters and climate change; exposure to liability relating to environmental and health and safety matters; limited ability to dispose of assets because of the relative illiquidity of real estate investments and the nature of our assets; exposure to litigation or other claims; risks associated with breaches of our data security; risks associated with our indebtedness, including failure to refinance current or future indebtedness on favorable terms, or at all, failure to meet the restrictive covenants and requirements in our existing and new debt agreements, fluctuations in interest rates and increased costs to refinance or issue new debt; risks associated with derivatives or hedging activity; risks associated with mortgage debt or unsecured financing or the unavailability thereof, which could make it difficult to finance or refinance properties and could subject us to foreclosure; adverse impacts from any future pandemic, epidemic or outbreak of any highly infectious disease on the U.S., regional and global economies and the financial condition and results of operations of the Company; and other risks and uncertainties detailed in the “Risk Factors” section of our Form 10-K for the year ended December 31, 2025, filed with the Securities and Exchange Commission, or the SEC, on February 23, 2026 and included under the heading “Risk Factors” in our other public filings. In addition, our qualification as a real estate investment trust involves the application of highly technical and complex provisions of the Internal Revenue Code of 1986, or the Code, and depends on our ability to meet the various requirements imposed by the Code through actual operating results, distribution levels and diversity of stock ownership. We assume no obligation to update publicly any forward-looking statements, whether as a result of new information, future events or otherwise.

Ratings

Ratings are not recommendations to buy, sell or hold the Company’s securities.

The following discussion related to the consolidated financial statements of the Company should be read in conjunction with the financial statements for the quarter ended March 31, 2026 that will be released in our Form 10-Q to be filed with the SEC on or about April 27, 2026.

This section contains definitions of certain non-GAAP financial measures and other terms that the Company uses in this Supplemental Information Package and, where applicable, the reasons why management believes these non-GAAP financial measures provide useful information to investors about the Company’s financial condition and results of operations and the other purposes for which management uses the measures. These measures should not be considered in isolation or as a substitute for measures of performance in accordance with GAAP. Additional detail can be found in the Company’s most recent quarterly report on Form 10-Q and the Company’s most recent annual report on Form 10-K, as well as other documents filed with or furnished to the SEC from time to time. We present certain financial information and metrics “at Easterly’s Share,” which is calculated on an entity-by-entity basis. “At Easterly’s Share” information, which we also refer to as being “at share,” “pro rata,” “our pro rata share” or “our share” is not, and is not intended to be, a presentation in accordance with GAAP.

Annualized lease income is defined as the annualized contractual base rent for the last month in a specified period, plus the annualized straight-line rent adjustments for the last month in such period and the annualized net expense reimbursements earned by us for the last month in such period.

Cash Available for Distribution (CAD) is a non-GAAP financial measure that is not intended to represent cash flow for the period and is not indicative of cash flow provided by operating activities as determined under GAAP. CAD is calculated in accordance with the current Nareit definition as FFO minus normalized recurring real estate-related expenditures and other non-cash items, nonrecurring expenditures and the unconsolidated real estate venture’s allocated share of these adjustments. CAD is presented solely as a supplemental disclosure because the Company believes it provides useful information regarding the Company’s ability to fund its dividends. Because all companies do not calculate CAD the same way, the presentation of CAD may not be comparable to similarly titled measures of other companies.

Cash fixed charge coverage ratio is calculated as EBITDA divided by the sum of principal amortization and interest expense, excluding amortization of premiums / discounts and deferred financing fees, for the most recent quarter.

Cash interest coverage ratio is calculated as EBITDA divided by interest expense, excluding amortization of premiums / discounts and deferred financing fees, for the most recent quarter.

Core Funds from Operations (Core FFO) adjusts FFO to present an alternative measure of the Company's operating performance, which, when applicable, excludes items which it believes are not representative of ongoing operating results, such as liability management related costs (including losses on extinguishment of debt and modification costs), catastrophic event charges, depreciation of non-real estate assets, provision for (recovery of) credit losses, and the unconsolidated real estate venture's allocated share of these adjustments. In future periods, the Company may also exclude other items from Core FFO that it believes may help investors compare its results. The Company believes Core FFO more accurately reflects the ongoing operational and financial performance of the Company's core business.

EBITDA is calculated as the sum of net income (loss) before interest expense, taxes, depreciation and amortization, (gain) loss on the sale of operating properties, impairment loss, and the unconsolidated real estate venture’s allocated share of these adjustments. EBITDA is not intended to represent cash flow for the period, is not presented as an alternative to operating income as an indicator of operating performance, should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP, is not indicative of operating income or cash provided by operating activities as determined under GAAP and may be presented on a pro forma basis. EBITDA is presented solely as a supplemental disclosure with respect to liquidity because the Company believes it provides useful information regarding the Company's ability to service or incur debt. Because all companies do not calculate EBITDA the same way, the presentation of EBITDA may not be comparable to similarly titled measures of other companies.

Fully diluted basis assumes the exchange of all outstanding common units representing limited partnership interests in the Company’s operating partnership, or common units, the full vesting of all shares of restricted stock, and the exchange of all earned and vested LTIP units in the Company’s operating partnership for shares of common stock on a one-for-one basis, which is not the same as the meaning of “fully diluted” under GAAP.

Funds From Operations (FFO) is defined, in accordance with the Nareit FFO White Paper - 2018 Restatement, as net income (loss), calculated in accordance with GAAP, excluding depreciation and amortization related to real estate, gains and losses from the sale of certain real estate assets, gains and losses from change in control and impairment write-downs of certain real estate assets and investments in entities when the impairment is directly attributable to decreases in the value of depreciable real estate held by the entity. FFO includes the Company’s share of FFO generated by unconsolidated affiliates. FFO is a widely recognized measure of REIT performance. Although FFO is a non-GAAP financial measure, the Company believes that information regarding FFO is helpful to shareholders and potential investors.

Net Debt and Adjusted Net Debt Net Debt represents the Company's consolidated debt and its share of unconsolidated debt adjusted to exclude its share of unamortized premiums and discounts and deferred financing fees, less its share of cash and cash equivalents and property acquisition closing escrow, net of deposit. By excluding these items, the result provides an estimate of the contractual amount of borrowed capital to be repaid, net of cash available to repay it. The Company believes this calculation constitutes a beneficial supplemental non-GAAP financial disclosure to investors in understanding its financial condition. Adjusted Net Debt is Net Debt reduced by 1) for each project under construction or in design, the lesser of i) outstanding lump-sum reimbursement amounts and ii) the cost to date, 2) 40% times the amount by which the cost to date exceeds total lump-sum reimbursement amounts for each project under construction or in design and 3) outstanding lump-sum reimbursement amounts for projects previously completed. These adjustments are made to 1) remove the estimated portion of each project under construction, in design or previously completed that has been financed with debt which may be repaid with outstanding cost reimbursement payments from the US Government and 2) remove the estimated portion of each project under construction or in design, in excess of total lump-sum reimbursements, that has been financed with debt but has not yet produced earnings. See page 28 for further information. The Company’s method of calculating Net Debt and Adjusted Net Debt may be different from methods used by other REITs and may be presented on a pro forma basis. Accordingly, the Company's method may not be comparable to such other REITs.

Net Operating Income (NOI) and Cash NOI NOI is calculated as net income adjusted to exclude depreciation and amortization, acquisition costs, corporate general and administrative costs, recovery of credit losses, interest expense, gains or losses from sales of property, impairment loss, and the unconsolidated real estate venture’s allocated share of these adjustments. Cash NOI excludes from NOI straight-line rent, amortization of above-/below-market leases, amortization of deferred revenue (which results from landlord assets funded by tenants), and the unconsolidated real estate venture’s allocated share of these adjustments. NOI and Cash NOI presented by the Company may not be comparable to NOI and Cash NOI reported by other REITs that define NOI and Cash NOI differently. The Company believes that NOI and Cash NOI provide investors with useful measures of the operating performance of its properties. NOI and Cash NOI should not be considered an alternative to net income as an indication of the Company's performance or to cash flows as a measure of the Company's liquidity or its ability to make distributions.
