ATLANTA, November 1, 2016 --Piedmont Office Realty Trust, Inc. ("Piedmont" or the "Company") (NYSE:PDM), an owner of primarily Class A office properties located in select sub-markets of major U.S. cities, today announced its results for the quarter ended September 30, 2016.

Highlights for the Three Months Ended September 30, 2016:

• Due to transactional activity, reported Net Loss Applicable to Common Stockholders of $0.09 per diluted share, as compared with $0.01 per diluted share for the three months ended September 30, 2015;
• Achieved Core Funds From Operations ("Core FFO") of $0.42 per diluted share, as compared with $0.41 per diluted share for the three months ended September 30, 2015;
• Completed over 700,000 square feet of leasing, of which almost half related to new tenant leases;
• Achieved a quarter-end leased percentage of 93.4%;
• Disposed of four non-core assets, generating approximately $107 million in sales proceeds; and
• Completed two acquisition transactions in the Company's targeted sub-markets.

Donald A. Miller, CFA, President and Chief Executive Officer, commented, "The third quarter was a busy one for us from both a leasing and transactional perspective. We completed over 700,000 square feet of leasing, with almost half of that leasing related to new tenants, resulting in net absorption for the quarter. We also continued to enhance the quality of the portfolio by selling off four non-strategic assets and thoughtfully reinvesting the proceeds in properties that are synergistic with our existing portfolio. Overall, we are pleased with our third quarter results and our momentum headed into the last quarter of the year."

Results for the Quarter ended September 30, 2016

Piedmont recognized net loss applicable to common stockholders for the three months ended September 30, 2016 of $12.7 million, or $0.09 per diluted share, as compared with a net loss of  $1.9 million, or $0.01 per diluted share, for the three months ended September 30, 2015. The three months ended September 30, 2016 included a non-cash impairment charge of $22.6 million, or $0.16 per diluted share, associated with the decision to sell 9200 and 9211 Corporate Boulevard, located in Rockville, MD, during the quarter. The same quarter of the prior year also included a non-cash impairment charge as well as gains on sale associated with various dispositions during the period.

Funds From Operations ("FFO"), which removes the impact of the impairment losses and gains on sales noted above, as well as depreciation and amortization, was $0.41 per diluted share for both the three months ended September 30, 2016 and 2015. Core FFO, which further removes the impact of acquisition costs and recovery from a casualty event was $0.42 per diluted share for the three months ended September 30, 2016, comparable to $0.41 per diluted share for the three months ended September 30, 2015. Adjusted Funds From Operations ("AFFO") was $50.5 million for the three months ended September 30, 2016, comparable to $52.4 million for the three months ended September 30, 2015.

Revenues for the three months ended September 30, 2016 were $138.5 million, as compared to $148.8 million for the same period a year ago, primarily due to the sale of thirteen assets since July 1, 2015, including our largest asset, Aon Center, during the fourth quarter of 2015. The decrease was partially offset by the acquisition of seven assets subsequent to July 1, 2015, new leases commencing, and overall occupancy gains over the last twelve months.

Property operating costs decreased approximately $6.8 million, from $61.7 million for the three months ended September 30, 2015 to $54.9 million for the three months ended September 30, 2016, primarily due to the asset sales mentioned above, partially offset by new properties acquired. Amortization expense increased by approximately $4.6 million for the three months ended September 30, 2016 as compared with the same quarter of the previous year due to intangible assets associated with new properties acquired since July 1, 2015.

General and administrative expense was $7.4 million for the three months ended September 30, 2016, compared to $8.3 million for the same period in 2015, primarily as a result of decreased accruals for potential stock based compensation expense during the current period. Due to the use of net proceeds from dispositions to pay down debt, interest expense decreased $3.3 million for the three months ended September 30, 2016 as compared to the three months ended September 30, 2015.

Leasing Update

The Company's leasing volume for the three months ended September 30, 2016 totaled over 700,000 square feet, of which almost one-half related to new tenant leasing. Leasing highlights for the quarter included an approximately 119,000 square foot, 12-year renewal and expansion with Synchronoss Technologies, Inc. at 200 Bridgewater Crossing in Bridgewater, NJ; an approximately 88,000 square foot new, 11-year lease with a technology division of a large, multi-national company at 4250 North Fairfax in Arlington, VA; an approximately 55,000 square foot 4+ year renewal and expansion at 80 Central Street in Boxborough, MA, with Lightower Fiber Networks, LLC; an approximately 54,000 square foot, 11+ year, new lease at 500 West Monroe Street in Chicago, IL; and an approximately 7+ year renewal of Convergys Customer Management Group, Inc's 50,000 square feet at 5601 Hiatus Road in Tamarac, FL.

The Company's overall portfolio was approximately 93.4% leased as of September 30, 2016, up 280 basis points from 90.6% a year ago, primarily as a result of transactional activity and the lease-up of vacant space during the quarter. Weighted average lease term remaining was approximately 7.0 years, up from 6.9 years at June 30, 2016. Same Store Cash NOI was $70.2 million for the three months ended September 30, 2016, up 4.5% compared to the same period in the prior year. Details outlining Piedmont's significant upcoming lease expirations, the status of current leasing activity, and a schedule of significant near-term abatement periods can be found in the Company's quarterly supplemental information package available at www.piedmontreit.com.

Transactional Activity

During the three months ended September 30, 2016, Piedmont acquired:

• A 99% interest in the entity that owns CNL Towers I and II, two trophy office buildings located in the heart of Orlando, FL's central business district, for a net purchase price of $166.7 million; and
   
• One Wayside Road, an approximately 200,000 square foot office building situated on 8.9 acres adjacent to Piedmont's 5&15 Wayside Road assets in Burlington, MA, for a net purchase price of $62.9 million.

Also during the quarter, Piedmont sold:

• 150 West Jefferson, an approximately 490,000 square foot, 88% leased, 25-story, office tower located in downtown Detroit, MI for $81.5 million; and
   
• 9200, 9211, and 9221 Corporate Boulevard, three four-story office buildings located in the same office park, totaling approximately 340,000 square feet. The buildings were sold in two separate transactions totaling $25.9 million and completed Piedmont's exit from the Rockville, MD submarket.

Subsequent to quarter end, Piedmont acquired Galleria 200, an 89% leased, multi-tenant, 20-story, approximately 430,000 square-foot, office building situated on 4.9 acres within Atlanta's master-planned "Galleria" development located directly across I-285 from the new Atlanta Braves stadium, SunTrust Park, for $69.6 million. The acquisition of Galleria 200 complements Piedmont's fourth quarter 2015 adjacent acquisition of Galleria 300 in that same office park.

Fourth Quarter Dividend Declaration

On November 1, 2016, the board of directors of Piedmont declared dividends for the fourth quarter of 2016 in the amount of $0.21 per share on its common stock to stockholders of record as of the close of business on November 25, 2016, payable on January 3, 2017.

Guidance for 2016

Based on completed capital markets transactions and leasing activity year to date, as well as management's expectations for the rest of 2016, the Company narrows its previous guidance for full-year 2016 as follows:

These estimates reflect management's view of current market conditions and incorporate certain economic and operational assumptions and projections. Actual results could differ materially from these estimates based on a variety of factors, including those discussed under "Forward Looking Statements" below. Note that individual quarters may fluctuate on both a cash basis and an accrual basis due to lease commencements and expirations, abatement periods, the timing of repairs and maintenance, capital expenditures, capital markets activities, seasonal general and administrative expenses, and one-time revenue or expense events. In addition, the Company's guidance is based on information available to management as of the date of this release.

Non-GAAP Financial Measures

To supplement the presentation of the Company's financial results prepared in accordance with U.S. generally accepted accounting principles ("GAAP"), this release and the accompanying quarterly supplemental information as of and for the period ended September 30, 2016 contain certain financial measures that are not prepared in accordance with GAAP, including FFO, Core FFO, AFFO, Same Store Cash NOI, Property NOI (cash basis) and Core EBITDA. Definitions and reconciliations of each of these non-GAAP measures to their most comparable GAAP metrics are included below and in the accompanying quarterly supplemental information.

Each of the non-GAAP measures included in this release and the accompanying quarterly supplemental financial information has limitations as an analytical tool and should not be considered in isolation or as a substitute for an analysis of the Company's results calculated in accordance with GAAP. In addition, because not all companies use identical calculations, the Company's presentation of non-GAAP measures in this release and the accompanying quarterly supplemental information may not be comparable to similarly titled measures disclosed by other companies, including other REITs. The Company may also change the calculation of any of the non-GAAP measures included in this news release and the accompanying supplemental financial information from time to time in light of its then existing operations to include other adjustments that may affect its operations.
