News Release FOR IMMEDIATE RELEASE DUKE REALTY REPORTS SECOND QUARTER 2021 RESULTS 36.2 Percent Growth in Net Effective Rents on Quarterly Leasing Activity In-Service Portfolio 97.9 Percent Leased 2021 Earnings and Development Guidance Increased (INDIANAPOLIS, July 28, 2021) – Duke Realty Corporation (NYSE: DRE), the largest domestic-only logistics REIT, today reported results for the second quarter of 2021. "I am happy to announce our second quarter operating results, which were highlighted by record performance for rent growth and in-service portfolio leasing percentage," said Jim Connor, Chairman and Chief Executive Officer. "We finished the quarter with our in- service portfolio 97.9 percent leased, which was the highest ever. We also recorded our highest quarterly rent growth ever on second generation leasing activity, with 36.2 percent growth in net effective rents and 19.2 percent growth on a cash basis. Growth in same- property net operating income of 5.5 percent for the quarter, compared to the second quarter of 2020, was mainly driven by rental rate growth and the expiration of free rent periods, which was especially impressive when considering that average occupancy in our same-property portfolio was 30 basis points lower than the very high level during the second quarter of 2020. As a result of our strong second quarter performance and improved outlook for the balance of the year, we are increasing our earnings guidance, along with positively adjusting guidance for several other related operational metrics." "We continued to access a variety of sources of capital to fund our increasing development pipeline," stated Mark Denien, Executive Vice President and Chief Financial Officer. "We generated $156 million of net cash proceeds through our ATM program and $183 million of proceeds from building sales during the second quarter. Additionally, we pre-funded further development activities by generating an additional $431 million of net cash proceeds from building sales and joint venture contributions completed during July, which includes our share of joint venture financing proceeds." Exhibit 99.1

Quarterly Highlights • A complete reconciliation, in dollars and per share amounts, of net income to funds from operations ("FFO"), as defined by Nareit, as well as to Core FFO, is included in the financial tables included in this release. • Net income was $0.47 per diluted share for the second quarter of 2021, compared to $0.11 per diluted share for the second quarter of 2020. Net income per diluted share for the quarter increased from the second quarter of 2020 due to higher gains on property sales, overall improved operating results and lower losses on debt extinguishment. • FFO, as defined by Nareit, was $0.43 per diluted share for the second quarter of 2021, compared to $0.33 per diluted share for the second quarter of 2020. The increased FFO, as defined by Nareit, was primarily driven by improved in-service occupancy, rental rate growth, new developments being leased and lower losses on debt extinguishment. • Core FFO was $0.44 per diluted share for the second quarter of 2021, compared to $0.38 per diluted share for the second quarter of 2020. The increased Core FFO per diluted share was primarily driven by improved occupancy, rental rate growth and new developments being leased. • Key indicators of the company's operating performance were as follows: – The company's stabilized in-service portfolio was 98.2 percent leased at June 30, 2021 compared to 98.1 percent leased at March 31, 2021 and 97.3 percent leased at June 30, 2020. – The company's total in-service portfolio was 97.9 percent leased at June 30, 2021 compared to 97.6 percent leased at March 31, 2021 and 96.7 percent leased at June 30, 2020. – The company's total portfolio, including properties under development, was 94.6 percent leased at June 30, 2021 compared to 95.5 percent leased at March 31, 2021 and 95.3 percent leased at June 30, 2020. – Tenant retention was 77.5 percent for the three months ended June 30, 2021 and 93.9 percent after considering immediate backfills. – Same-property net operating income growth was 5.5 percent and 6.2 percent for the three and six month periods ended June 30, 2021 compared to the same periods in 2020. Same-property net operating income growth for the quarter was primarily due to rental rate growth and the expiration of free rent Duke Realty Reports Second Quarter 2021 Results July 28, 2021 Page 2 of 9

periods, partially offset by a 30 basis point decrease in occupancy within our same-property portfolio. – Total leasing activity was 7.6 million square feet for the quarter. – Overall cash and annualized net effective rent growth on new and renewal leases was 19.2 percent and 36.2 percent, respectively, for the quarter. • Capital transactions included: – Five new speculative development projects with expected costs of $197 million started during the quarter; – Income producing real estate acquisitions totaling $260 million for the quarter; – Building dispositions totaling $183 million for the quarter; – Extinguishment of $84 million of unsecured notes that bore interest at a 3.93 percent effective rate and were scheduled to mature in October 2022; – Issuance of 3.4 million shares during the quarter, generating $156 million of net proceeds, under the company's ATM program at an average price of $46.35 per share. Real Estate Investment Activity “We started five speculative projects, with expected costs of $197 million, during the second quarter and our development projects under construction were 49 percent leased at June 30, 2021, including these second quarter speculative development starts," said Mr. Connor. "Our track record for leasing speculative developments has been impressive, as evidenced by the fact that we have leased 10 out of our last 12 speculative developments in Southern California prior to, or immediately after, being placed in service. Another very recent success is the 582,000 square foot building that we started on a speculative basis in Columbus early in the second quarter, for which we signed a full-building lease in July. The leasing prospects for our other second quarter speculative starts are very strong. As of June 30, 2021, 97 percent of our undeveloped land inventory was concentrated in coastal Tier One markets, where most of our future speculative developments will take place. To continue to replenish our land inventory in coastal markets and maintain our pace of development we have several additional sites under contract and in various stages of due diligence and permitting. During the quarter, we acquired a 766,000 square foot property in Southern California as well as a 38 acre container storage yard in Northern New Jersey. The Southern California building is a unique, big box asset with extra trailer parking and is near the Ontario airport in the Inland Empire West submarket. The property in Northern New Jersey is within one Duke Realty Reports Second Quarter 2021 Results July 28, 2021 Page 3 of 9

mile of the ports of New York and New Jersey. Both properties have leases in place that are significantly below market, providing future rental growth opportunities. As separately announced yesterday, we created a new joint venture with CBRE Global Investors, to which we will contribute certain identified single tenant properties, which are leased to Amazon, in three tranches. The closing of the first tranche of properties contributed to this joint venture took place earlier this week and generated net cash proceeds of $141 million, which includes our share of joint venture financing proceeds. The second tranche will consist of two buildings and one trailer storage lot in Baltimore and is expected to close by the end of the third quarter. The third tranche, which we expect to close early next year, will consist of three properties in South Florida, Eastern Pennsylvania and Seattle. On July 22, we closed on the sale of 14 buildings and 15 acres of undeveloped land in St. Louis, receiving net cash proceeds of $290 million. With this sale, we have completed our exit from the St. Louis market." Development The second quarter included the following development activity: Consolidated Properties • The company started four speculative development projects, with expected costs of $160 million, totaling 1.6 million square feet. These development starts included two projects in Southern California totaling 372,000 square feet; a 371,000 square foot project in Chicago and an 820,000 square foot project in Savannah. • Two projects, totaling 1.5 million square feet, were placed in service during the second quarter that were comprised of a 100 percent leased, 1.1 million square foot project in Southern California and a 100 percent leased, 415,000 square foot project in Eastern Pennsylvania. Unconsolidated Joint Venture Properties • A 582,000 square foot speculative development project was started in Columbus by a 50 percent-owned joint venture. In July 2021, a lease with a single user was signed for the entire building. Acquisitions Income producing real estate acquisitions totaled $260 million in the second quarter and included the following properties: • A 766,000 square foot, 100 percent leased property in Southern California; and • A 38 acre, 100 percent-leased, container storage yard in Northern New Jersey.

Building Dispositions Building dispositions totaled $183 million in the second quarter and included the following: Consolidated Properties • Two 100 percent leased projects in Raleigh totaling 298,000 square feet; and • An 855,000 square foot, 100 percent leased, project in St. Louis. Unconsolidated Joint Venture Properties • A 358,000 square foot, 100 percent leased, project in Columbus was sold by a 50 percent-owned joint venture. Distributions Declared The company's board of directors declared a quarterly cash distribution on its common stock of $0.255 per share, or $1.02 per share on an annualized basis. The second quarter dividend will be payable on August 31, 2021 to shareholders of record on August 16, 2021. 2021 Earnings Guidance A reconciliation of the company's guidance for diluted net income per common share to FFO, as defined by Nareit, and to Core FFO is included in the financial tables to this release. The company issued revised guidance for net income of $2.13 to $2.39 per diluted share, compared to the previous range of $1.86 to $2.24 per diluted share. The company issued revised guidance for FFO, as defined by Nareit, of $1.62 to $1.68 per diluted share, compared to the previous range of $1.60 to $1.70 per diluted share. "As the result of our exceptional performance thus far in 2021, we have revised our guidance in several areas," said Mr. Denien. "Our 2021 guidance for Core FFO has been revised to $1.69 to $1.73 per diluted share, compared to the previous range of $1.65 to $1.71 per diluted share. At the midpoint, this represents 12.5 percent growth over 2020. Our guidance for growth in Adjusted Funds from Operations ("AFFO"), on a share adjusted basis, has been revised to between 10.1 percent and 13.0 percent, compared to the previous range of 8.0 percent to 12.3 percent. Our increased guidance is the result of our strong leasing performance thus far, with total leasing volume of 15.1 million square feet for the first six months of the year, which is especially impressive considering our already high level of occupancy. Our expectation is for continued strong leasing activity for the remainder of the year and minimal bad debt expense and tenant defaults. Accordingly, we have also revised our guidance for the average percentage leased of our stabilized portfolio to a range of 97.8 percent to 98.6 percent, compared to the previous range of 97.2 percent to 98.6 percent, and revised our Duke Realty Reports Second Quarter 2021 Results July 28, 2021 Page 5 of 9

guidance for the average percentage leased of our total in-service portfolio to a range of 97.1 percent to 97.9 percent, compared to the previous range of 96.3 percent to 97.7 percent. These factors, along with strong rental rate growth on recently executed leases, resulted in revised guidance for growth in same-property net operating income (cash basis) to between 4.75 percent and 5.25 percent, compared to the previous range of 4.1 percent to 4.9 percent. We also increased our guidance for same-property net operating income (net effective basis) to between 3.75 percent and 4.25 percent, compared to the previous range of between 3.1 percent and 3.9 percent. Our guidance for dispositions of properties has been revised to between $1.00 billion and $1.20 billion, compared to the previous range of $900 million to $1.10 billion. The increase in disposition proceeds is a result of better-than-expected pricing. We have already closed on the sale of our entire St. Louis portfolio along with closing the first tranche of properties being contributed to our newly formed 20 percent-owned joint venture. Our guidance for 2021 development starts has been revised to between $1.10 billion and $1.30 billion, compared to the previous range of $950 million to $1.15 billion, with a continuing target to maintain the pipeline at a healthy level of pre-leasing. We have increased our guidance for development starts based on leasing success thus far, our expectation of continuing to lease speculative space as well as our solid pipeline of build- to-suit prospects." Other guidance changes are as follows: • Acquisitions of properties in a range of $350 million to $550 million, concentrated on coastal in-fill markets, compared to the previous range of between $300 million and $500 million. • General and administrative expenses ranging from $61 million to $65 million, compared to the previous range of between $57 million and $61 million. More specific assumptions and components of the company's 2021 guidance will be available by 6 p.m. Eastern Time today through the Investor Relations section of the company's website. FFO and AFFO Reporting Definitions FFO: FFO is a non-GAAP performance measure computed in accordance with standards established by the National Association of Real Estate Investment Trusts (“Nareit"). It is calculated as net income attributable to common shareholders computed in accordance with generally accepted accounting principles (“GAAP"), excluding depreciation and amortization related to real estate, gains and losses on sales of real estate assets (including real estate assets incidental to our business), gains and losses from change in Duke Realty Reports Second Quarter 2021 Results July 28, 2021 Page 6 of 9

control, impairment charges related to real estate assets (including real estate assets incidental to our business) and similar adjustments for unconsolidated joint ventures and partially owned consolidated entities, all net of related taxes. We believe FFO to be most directly comparable to net income attributable to common shareholders as defined by GAAP. FFO does not represent a measure of liquidity, nor is it indicative of funds available for our cash needs, including our ability to make cash distributions to shareholders. Core FFO: Core FFO is computed as FFO adjusted for certain items that can create significant earnings volatility and do not directly relate to our core business operations. The adjustments include gains or losses on debt transactions, gains or losses from involuntary conversion from weather events or natural disasters, promote income, severance and other charges related to major overhead restructuring activities and the expense impact of costs attributable to successful leasing activities. Although our calculation of Core FFO differs from Nareit’s definition of FFO and may not be comparable to that of other REITs and real estate companies, we believe it provides a meaningful supplemental measure of our operating performance. AFFO: AFFO is defined by the company as the Core FFO (as defined above), less recurring building improvements and total second generation capital expenditures (the leasing of vacant space that had previously been under lease by the company is referred to as second generation lease activity) related to leases commencing during the reporting period, and adjusted for certain non-cash items including straight line rental income and expense, non-cash components of interest expense including interest rate hedge amortization, stock compensation expense and after similar adjustments for unconsolidated partnerships and joint ventures. Same-Property Performance The company includes same-property net operating income growth as a property-level supplemental measure of performance. The company utilizes same-property net operating income growth as a supplemental measure to evaluate property-level performance, and jointly-controlled properties are included at the company's ownership percentage. A reconciliation of income from continuing operations before income taxes to same- property net operating income is included in the financial tables to this release. A description of the properties that are excluded from the company’s same-property net operating income measure is included on page 16 of its June 30, 2021 supplemental information.
