If Washington REIT were to conduct an offering of securities in the future, it will be made under an effective registration statement filed with the Securities and Exchange Commission and only by means of a prospectus supplement and accompanying prospectus. In such an event, a copy of the prospectus and the applicable preliminary prospectus supplement and final prospectus supplement, as well the final term sheet, relating to such transaction will be able to be obtained from the Securities and Exchange Commission atwww.sec.gov, by the underwriters in that offering, or by contacting Washington REIT at 202-774-3200.

Forward-Looking Statements

Certain statements in this presentation are "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements relate to expectations, beliefs, projections, future plans and strategies, anticipated events or trends and similar expressions concerning matters that are not historical facts. In some cases, you can identify forward looking statements by the use of forward-looking terminology such as "may," "will," "should," "expects," "intends," "plans," "anticipates," "believes," "estimates," "predicts,"or "potential" or the negative of these words and phrases or similar words or phrases which are predictions of or indicate future events or trends and which do not relate solely to historical matters. Such statements involve known and unknown risks, uncertainties, and other factors which may cause the actual results, performance, or achievements of WashREIT to be materially different from future results, performance or achievements expressed or implied by such forward looking statements. Currently, one of the most significant factors is the potential adverse effect of the COVID-19 virus and ensuing economic turmoil on the financial condition, results of operations, cash flows and performance of the WashREIT, particularly our ability to collect rent, on the financial condition, results of operations, cash flows and performance of our tenants, and on the global economy and financial markets. The extent to which COVID-19 impacts WashREIT and its tenants will depend on future developments, which are highly uncertain and cannot be predicted with confidence, including the scope, severity and duration of the pandemic, the actions taken to contain the pandemic or mitigate its impact, and the direct and indirect economic effects of the pandemic and containment measures, among others. Moreover, investors are cautioned to interpret many of the risks identified in the risk factors discussed in our Annual Report on Form 10-K for the year ended December 31, 2019, as amended by Amendment No. 1 to the Annual Report on Form 10-K, filed on March 6, 2020, as well as the risks set forth below, as being heightened as a result of the ongoing and numerous adverse impacts of COVID-19. Additional factors which may cause the actual results, performance, or achievements of WashREIT to be materially different from future results, performance or achievements expressed or implied by such forward-looking statements include, but are not limited to the risks associated with the ownership of real estate in general and our real estate assets in particular; the economic health of the greater Washington metro region; the risk of failure to enter into/and or complete contemplated acquisitions and dispositions at all, within the price ranges anticipated and on the terms and timing anticipated; changes in the composition of our portfolio; fluctuations in interest rates; reductions in or actual or threatened changes to the timing of federal government spending; the risks related to use of third-party providers and joint venture partners; the ability to control our operating expenses; the economic health of our tenants; the supply of competing properties; shifts away from brick and mortar stores to ecommerce; compliance with applicable laws, including those concerning the environment and access by persons with disabilities; terrorist attacks or actions and/or cyber-attacks; weather conditions, natural disasters and pandemics; ability to maintain key personnel; failure to qualify and maintain our qualification as a REIT and the risks of changes in laws affecting REITs; and other risks and uncertainties detailed from time to time in our filings with the SEC, including our 2019 Form 10-K, as amended by Amendment No. 1 to the Annual Report on Form 10-K, filed on March 6, 2020, and subsequent Quarterly Reports on Form 10-Q. While forward-looking statements reflect our good faith beliefs, they are not guarantees of future performance. We undertake no obligation to update our forward-looking statements or risk factors to reflect new information, future events, or otherwise.

Use of Non-GAAP Financial Measures and other Definitions

This presentation contains certain non-GAAP financial measures and other terms that have particular definitions when used by us. The definitions and calculations of these non-GAAP financial measures and other terms may differ from those used by other REITs and, accordingly, may not be comparable. Please refer to the definitions and calculations of these terms and the reasons for their use, and reconciliations to the most directly comparable GAAP measures included later in this investor presentation.

Reconciliation

This presentation also includes certain forward-looking non-GAAP information. Due to the high variability and difficulty in making accurate forecasts and projections of some of the information excluded from these estimates, together with some of the excluded information not being ascertainable or accessible, the Company is unable to quantify certain amounts that would be required to be included in the most directly comparable GAAP financial measures without unreasonable efforts.

Market Data

Market data and industry forecasts are used in this presentation, including data obtained from publicly available sources. These sources generally state that the information they provide has been obtained from sources believed to be reliable, but the accuracy and completeness of the information is not assured. The Company has not independently verified any such information.

RESEARCH-DRIVEN CAPITAL ALLOCATION

Research-led multifamily investment strategy has strengthened and stabilized our portfolio and reduced risk

Multifamily Investment Strategy:

•  Maximize Class B rental growth by uncovering submarkets that offer the widest differential, i.e. "affordability gap," between Class A and Class B unit rents

•  Invest in submarkets near major job centers that have limited competitive supply

•  Bolster rent growth with value-add unit renovations at compelling returns

•  Capitalized on excess parking fields by adding on-site density (Trove, 401 units) and future opportunity to add 767 units at Riverside

Multifamily Investments:

•  The Wellington, Arlington, VA in 2015

•  Riverside Apartments, Alexandria, VA in 2016

•  The Assembly Portfolio in VA + MD in 2019

•  Cascade at Landmark, Alexandria, VA in 2019

•  Delivered Trove development in Arlington, VA in 2020

$1.1 Billion of Value-Oriented Multifamily Investments since 2015

Since 2013, we have completed ~$3.7bn of strategic portfolio transactions to increase our exposure to value-oriented multifamily investments while reducing concentrations of non-core retail and office assets

AFFORDABILITY STRATEGY OVERVIEW

WashREIT's strategy seeks to maximize Class B rental growth by uncovering submarkets offering a wider than average differential, i.e. "affordability gap," between Class A and Class B unit rents. These provide an opportunity for Class B unit renovations with a mid-teen return on investment.

ESG INITIATIVES

Urban Ecosystem

We have an entire food system housed in one building - from the bees pollinating the garden to the restaurant harvesting the produce and the building compost completing the circle.

Employee & Community Engagement

We believe the most valuable investments we make are in our people and community. We place great value on employee growth and development. And we give back to our community, most visibly through our annual company-wide community service day.

Supporting our Community with Clean EnergyRisk Management

We have solar panels on the roof of our headquarters building and the clean energy produced is credited to low-and moderate-income families at Jubilee Housing, a provider of deeply affordable housing in Washington, D.C.

We have established a company-wide focus on business continuity preparedness and cybersecurity prevention over the past several years. Our robust tools and resources have allowed us to work and collaborate remotely, performing to the highest standards without disruption during the global health crisis.

SAME-STORE PORTFOLIO FROM Q4 2020 SUPPLEMENT

1) For a list of non same-store, discontinued operations and other properties, see "Same-Store Portfolio Net Operating Income (NOI) Growth 2020 vs 2019"

DEFINITIONS

Adjusted EBITDA (a non-GAAP measure) is earnings before interest expense, taxes, depreciation, amortization, gain/loss on sale of real estate, casualty gain/loss, real estate impairment, gain/loss on extinguishment of debt, restructuring expenses (which include severance, accelerated share-based compensation and other expenses related to a restructuring of corporate personnel), acquisition expenses and gain from non-disposal activities.

Annualized base rent ("ABR") is calculated as monthly base rent (cash basis) per the lease, as of the reporting period, multiplied by 12.

Average occupancy is based on monthly occupied net rentable square footage as a percentage of total net rentable square footage, except for the rows labeled "Multifamily (calculated on a unit basis)," on which average occupancy is based on average monthly occupied units as a percentage of total units. The square footage for multifamily properties only includes residential space. The occupied square footage for office and retail properties includes temporary lease agreements.

Debt service coverage ratio is computed by dividing earnings attributable to the controlling interest before interest expense, taxes, depreciation, amortization, real estate impairment, gain on sale of real estate, gain/loss on extinguishment of debt, severance expense, relocation expense, acquisition and structuring expenses and gain/loss from non-disposal activities by interest expense (including interest expense from discontinued operations) and principal amortization.

Debt to total market capitalization is total debt divided by the sum of total debt plus the market value of shares outstanding at the end of the period.

Earnings to fixed charges ratio is computed by dividing earnings attributable to the controlling interest by fixed charges. For this purpose, earnings consist of income from continuing operations (or net income if there are no discontinued operations) plus fixed charges, less capitalized interest. Fixed charges consist of interest expense (excluding interest expense from discontinued operations), including amortized costs of debt issuance, plus interest costs capitalized.

Ending Occupancy is calculated as occupied square footage as a percentage of total square footage as of the last day of that period. Multifamily unit basis ending occupancy is calculated as occupied units as a percentage of total units as of the last day of that period.

NAREIT Funds from operations ("NAREIT FFO") is defined by National Association of Real Estate Investment Trusts, Inc. ("NAREIT") in its NAREIT FFO White Paper - 2018 Restatement, as net income (computed in accordance with generally accepted accounting principles ("GAAP") excluding gains (or losses) associated with sales of property, impairment of depreciable real estate and real estate depreciation and amortization. We consider NAREIT FFO to be a standard supplemental measure for equity real estate investment trusts ("REITs") because it facilitates an understanding of the operating performance of our properties without giving effect to real estate depreciation and amortization, which historically assumes that the value of real estate assets diminishes predictably over time. Since real estate values have instead historically risen or fallen with market conditions, we believe that NAREIT FFO more accurately provides investors an indication of our ability to incur and service debt, make capital expenditures and fund other needs. Our FFO may not be comparable to FFO reported by other real estate investment trusts. These other REITs may not define the term in accordance with the current NAREIT definition or may interpret the current NAREIT definition differently. NAREIT FFO is a non-GAAP measure.

Core Funds From Operations ("Core FFO") is calculated by adjusting NAREIT FFO for the following items (which we believe are not indicative of the performance of Washington REIT's operating portfolio and affect the comparative measurement of Washington REIT's operating performance over time): (1) gains or losses on extinguishment of debt, (2) expenses related to acquisition and structuring activities, (3) executive transition costs, severance expenses and other expenses related to corporate restructuring and related to executive retirements or resignations, (4) property impairments, casualty gains and losses, and gains or losses on sale not already excluded from NAREIT FFO, as appropriate, and (5) relocation expense. These items can vary greatly from period to period, depending upon the volume of our acquisition activity and debt retirements, among other factors. We believe that by excluding these items, Core FFO serves as a useful, supplementary measure of Washington REIT's ability to incur and service debt, and distribute dividends to its shareholders. Core FFO is a non-GAAP and non-standardized measure, and may be calculated differently by other REITs.

Funds Available for Distribution ("FAD") is calculated by subtracting from NAREIT FFO (1) recurring expenditures, tenant improvements and leasing costs, that are capitalized and amortized and are necessary to maintain our properties and revenue stream (excluding items contemplated prior to acquisition or associated with development / redevelopment of a property) and (2) straight line rents, then adding (3) non-real estate depreciation and amortization, (4) non-cash fair value interest expense and (5) amortization of restricted share compensation, then adding or subtracting the (6) amortization of lease intangibles, (7) real estate impairment and (8) non-cash gain/loss on extinguishment of debt, as appropriate. FAD is included herein, because we consider it to be a performance measure of a REIT's ability to incur and service debt and to distribute dividends to its shareholders. FAD is a non-GAAP and non-standardized measure, and may be calculated differently by other REITs.

Core Funds Available for Distribution ("Core FAD") is calculated by adjusting FAD for the following items (which we believe are not indicative of the performance of Washington REIT's operating portfolio and affect the comparative measurement of Washington REIT's operating performance over time): (1) gains or losses on extinguishment of debt, (2) costs related to the acquisition of properties, (3) non-share-based executive transition costs, severance expenses and other expenses related to corporate restructuring and related to executive retirements or resignations, (4) property impairments, casualty gains and losses, and gains or losses on sale not already excluded from FAD, as appropriate, and (5) relocation expense. These items can vary greatly from period to period, depending upon the volume of our acquisition activity and debt retirements, among other factors. We believe that by excluding these items, Core FAD serves as a useful, supplementary performance measure of Washington REIT's ability to incur and service debt, and distribute dividends to its shareholders. Core FAD is a non-GAAP and non-standardized measure, and may be calculated differently by other REITs.

Net Operating Income ("NOI") is a non-GAAP measure defined as real estate rental revenue less real estate expenses. NOI is calculated as net income, less non-real estate revenue and the results of discontinued operations (including the gain or loss on sale, if any), plus interest expense, depreciation and amortization, general and administrative expenses, acquisition costs, real estate impairment, casualty gains and losses, and gain or loss on extinguishment of debt. We also present NOI on a cash basis ("Cash NOI") which is calculated as NOI less the impact of straightlining of rent and amortization of market intangibles. We provide each of NOI and cash NOI as a supplement to net income calculated in accordance with GAAP. As such, neither should be considered an alternative to net income as an indication of our operating performance. They are the primary performance measures we use to assess the results of our operations at the property level.

Recurring capital expenditures represent non-accretive building improvements and leasing costs required to maintain current revenues. Recurring capital expenditures do not include acquisition capital that was taken into consideration when underwriting the purchase of a building or which are incurred to bring a building up to "operating standard."

Rent increases on renewals and rollovers are calculated as the difference, weighted by square feet, of the net ABR due the first month after a term commencement date and the net ABR due the last month prior to the termination date of the former tenant's term. Beginning in Q4 2018, in cases where the space has been remeasured in accordance with criteria set by the Building Owners and Managers Association ("BOMA"), the square feet former tenant's space is adjusted to be equivalent to the square feet of the new/renewing tenant's space.

Same-store portfolio properties include properties that were owned for the entirety of the years being compared, and exclude properties under redevelopment or development and properties acquired, sold or classified as held for sale during the years being compared. We define development properties as those for which we have planned or ongoing major construction activities on existing or acquired land pursuant to an authorized development plan. We consider a property's development activities to be complete when the property is ready for its intended use. The property is categorized as same-store when it has been ready for its intended use for the entirety of the years being compared. We define redevelopment properties as those for which have planned or ongoing significant development and construction activities on existing or acquired buildings pursuant to an authorized plan, which has an impact on current operating results, occupancy and the ability to lease space with the intended result of a higher economic return on the property. We categorize a redevelopment property as same-store when redevelopment activities have been complete for the majority of each year being compared.

Same-store portfolio NOI growth is the change in the NOI of the same-store portfolio properties from the prior reporting period to the current reporting period.
