Piedmont Office Realty Trust Reports Fourth Quarter and Annual 2012 Results and 2013 Guidance

ATLANTA, February 7, 2013 --Piedmont Office Realty Trust, Inc. ("Piedmont" or the "Company") (NYSE:PDM), an owner of primarily Class A properties located predominantly in the ten largest U.S. office markets, today announced its results for the quarter and year ended December 31, 2012.

Highlights for the Three Months and Year Ended December 31, 2012:

• Completed 898,000 square feet of leasing during the fourth quarter bringing total year to date leasing to approximately 3.4 million square feet;  

• Achieved Core Funds From Operations ("CFFO") of $0.36 per diluted share and $1.43 per diluted share for the quarter and year ended December 31, 2012, respectively;

• Continued to advance our portfolio repositioning strategy during 2012 by selling seven assets at a gain of $27.6 million, allowing us to exit two additional markets and dispose of our last two industrial assets;

• Repurchased 0.5 million shares of our common stock at an average price of $17.48 per share during the quarter, bringing the total shares repurchased since commencing the program in December 2011 to 5.5 million shares at an average price of $16.83;

• Paid off $185 million in secured debt and replaced our expiring unsecured line of credit with a comparable $500 million line;

• Expanded the capability and experience of our executive team with the addition of two officers;

• Received a favorable motion for summary judgment and a motion to dismiss in two class action lawsuits.

Donald A. Miller, CFA, President and Chief Executive Officer stated, “I am pleased with what we have accomplished this past year. We made strides in many different areas that I believe will all be beneficial to the Company as we move into 2013 and beyond. Although 2012 was a big year of lease expirations, our occupancy percentage actually increased as we successfully completed a large number of renewals and new leases. We also made progress in continuing to pare down the number of markets we operate in, while realizing meaningful gains for our stockholders. We were able to redeploy some of the proceeds from those asset sales into repurchases of our common stock on favorable terms. In addition, our balance sheet is in great shape, we've expanded our management team and tentatively settled two lawsuits. All of those items taken together make us well positioned to move forward.”

Results for the Fourth Quarter ended December 31, 2012

Piedmont's net income available to common stockholders for the fourth quarter of 2012, was $14.4 million, or $0.09 per diluted share, as compared with $119.0 million, or $0.69 per diluted share, for the fourth quarter of 2011. The prior year included $5.6 million, or $0.03 per diluted share, in operating income associated with eight properties that were sold during or subsequent to the fourth quarter of 20ll. The largest of these sold properties, the 35 W. Wacker Drive building, was sold during the fourth quarter of 2011 and resulted in the recognition of a $96.1 million, or $0.55 per diluted share, gain on sale during the fourth quarter of 2011. In addition, the current quarter's results include approximately $5.2 million, or

$0.03 per diluted share, in net casualty loss associated with losses incurred at certain of the Company's assets as a result of Hurricane Sandy.

Revenues for the quarter ended December 31, 2012 were $136.1 million, as compared with $135.6 million for the same period a year ago, primarily reflecting increased revenues associated with the commencement of several significant leases during the year ended 2012, offset by a reduction in reimbursement income associated with increased vacancy and abatement periods at certain properties.

Property operating costs were $55.1 million for the quarter ended December 31, 2012 which was comparable to the prior period. General and administrative expense decreased $1.1 million to $5.1 million due to lower compensation expense recorded during the current quarter.

FFO for the current quarter, which includes the $0.03 per diluted share casualty loss mentioned above, totaled $54.8 million, or $0.33 per diluted share, as compared with $65.9 million, or $0.38 per diluted share, for the quarter ended December 31, 2011. The prior quarter included $0.03 per diluted share in FFO contribution associated with eight properties that were sold during or subsequent to the fourth quarter of 20ll.

Core FFO, which excludes the casualty loss mentioned above, as well as $53,000 in transaction costs associated with a land acquisition during the quarter, totaled $60.1 million, or $0.36 per diluted share, for the current quarter, as compared to $65.3 million, or $0.38 per diluted share, for the quarter ended December 31, 2011. The prior quarter included $0.03 per diluted share in Core FFO contribution associated with eight properties that were sold during or subsequent to the fourth quarter of 20ll.

Adjusted FFO (“AFFO”) for the fourth quarter of 2012 totaled $31.3 million, or $0.19 per diluted share, as compared to $44.7 million, or $0.26 per diluted share, in the fourth quarter of 2011.

Results for the Year Ended December 31, 2012

Piedmont's net income available to common stockholders for the year ended 2012 was $93.2 million, or $0.55 per diluted share, as compared with $225.0 million, or $1.30 per diluted share, for the prior year. The prior year included $140.0 million, or $0.81 per diluted share, in operating income and gain on sales associated with ten properties that were sold subsequent to January 1, 20ll, whereas the current year only included $29.4 million, or $.17 per diluted share, of such income. Additionally, the current year's results include approximately $12.7 million, or $0.07 per diluted share, in net casualty losses and litigation settlement expense, whereas the prior year's results include approximately $9.1 million, or $0.05 per diluted share, in non-recurring income associated with the foreclosure and consolidation of the 500 W. Monroe building and higher lease termination income.

Revenues for the year ended December 31, 2012 were $536.4 million, as compared with $533.5 million for the prior year, primarily reflecting increased revenues associated with the commencement of several significant leases during the year ended 2012, offset by a reduction in reimbursement income associated with vacancies or rent abatements at certain properties and a $3.7 million reduction in lease termination income.

Property operating expenses were $212.9 million for the year ended December 31, 2012, as compared with $207.2 million for the prior year, primarily reflecting increased property tax expense as the prior year results included certain one time refunds due to successful appeals. General and administrative expense decreased $4.3 million from $25.1 million for the year ended December 31, 2011 to $20.8 million for the

year ended December 31, 2012, primarily due to decreased legal expense and decreased compensation expense recorded in the current year.

FFO for the current year totaled $230.4 million, or $1.35 per diluted share, which includes the $0.07 per diluted share in casualty losses and litigation settlement expense mentioned above, as compared with $271.3 million, or $1.57 per diluted share, for the year ended December 31, 2011. Additionally, the prior year included $0.16 per diluted share more in FFO contribution associated with ten properties that were sold subsequent to January 1, 20ll, as well as approximately $0.04 per diluted share in non-recurring FFO contribution associated with the foreclosure and consolidation of the 500 W. Monroe building and higher lease termination income.

Core FFO, which excludes the casualty and litigation settlement expenses mentioned above, as well as $141,000 in transaction costs associated with two land acquisitions during the year, totaled $243.2 million, or $1.43 per diluted share, for the current year, as compared to $271.6 million, or $1.57 per diluted share, for the year ended December 31, 2011. The prior year included $0.16 per diluted share more in Core FFO contribution associated with ten properties that were sold subsequent to January 1, 20ll as well as approximately $0.04 in non-recurring Core FFO contribution associated with the foreclosure and consolidation of the 500 W. Monroe building and higher lease termination income.

AFFO for the year ended December 31, 2012 totaled $138.0 million, or $0.81 per diluted share, as compared to $202.6 million, or $1.17 per diluted share, for the year ended December 31, 2011, reflecting the impact of the above items as well as increased capital expenditures associated with the commencement of certain large leases during the current year.

Leasing Update

During the fourth quarter of 2012, the Company executed approximately 898,000 square feet of leasing throughout its markets bringing Piedmont's year to date total square footage leased to approximately 3.4 million. Of the leases signed during the quarter, 616,000 square feet, or 69%, was renewal-related and 282,000 square feet, or 31%, was with new tenants.

Same store net operating income (on a cash basis) for the quarter was $70.9 million compared to $69.4 million for the quarter ended December 31, 2011, reflecting the positive effect of recent leasing activity.

Details outlining Piedmont's significant upcoming lease expirations and the status of current leasing activity can be found in the Company's quarterly supplemental information package.

Capital Markets, Financing and Other Activities

During the quarter, the Company purchased 0.5 million shares of its common stock at an average purchase price of $17.48 per share, bringing the total

Net debt to annualized core EBITDA ratio was 4.6 times and the Company`s fixed charge coverage ratio was 4.7 times. As of December 31, 2012, Piedmont had cash and capacity on its unsecured line of credit of approximately $364.5 million.

During the quarter ended December 31, 2012, the Company paid a quarterly dividend in the amount of $0.20 per share, bringing total dividends paid for the year ended December 31, 2012, to $0.80 per share. The Company anticipates announcing its first quarter 2013 dividend following its next regularly scheduled quarterly board meeting later this month.

Guidance for 2013

Based on management's expectations, the Company introduced its financial guidance for full-year 2013 as follows:

Low    High

Net Income                        $80 --    98 Million

Add: Depreciation and Amortization            $155 -- 160 Million

Deduct: Estimated Insurance Recoveries        $10 -- 15 Million

Core FFO                        $225 -    243 Million

Core FFO per diluted share                $1.35 - $1.45

These estimates reflect management's view of current market conditions and incorporate certain economic and operational assumptions and projections such as the anticipated move out of a significant governmental tenant and the decrease in net operations as a result of the sale of seven assets during 2012. This annual guidance includes the continued repositioning of the portfolio with dispositions approximating $300 million and acquisitions estimated to be $400 million during 2013. Actual results could differ from these estimates. Note that individual quarters may fluctuate on both a cash basis and an accrual basis due to lease commencements and expirations, the timing of repairs and maintenance, capital expenditures, capital markets activities 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.

⁽¹⁾  Includes adjustments for consolidated properties, including discontinued operations, and for our proportionate share of amounts attributable to unconsolidated joint ventures.

⁽²⁾  Excludes depreciation of non real estate assets.

⁽³⁾  Capital expenditures of a recurring nature related to tenant improvements and leasing commissions that do not incrementally enhance the underlying assets' income generating capacity. Tenant improvements, leasing commissions, building capital and deferred lease incentives incurred to lease space that was vacant at acquisition, leasing costs for spaces vacant for greater than one year, leasing costs for spaces at newly acquired properties for which in-place leases expire shortly after acquisition, improvements associated with the expansion of a building and renovations that change the underlying classification of a building are excluded from this measure.

*Definitions

Funds From Operations ("FFO"):FFO is calculated in accordance with the current National Association of Real Estate Investment Trusts ("NAREIT") definition. NAREIT currently defines FFO as net income (computed in accordance with GAAP), excluding gains or losses from sales of property and impairment losses, adding back depreciation and amortization on real estate assets, and after the same adjustments for unconsolidated partnerships and joint ventures. These adjustments can vary among owners of identical assets in similar conditions based on historical cost accounting and useful-life estimates. FFO may provide valuable comparisons of operating performance between periods and with other REITs. FFO is a non-GAAP financial measure and should not be viewed as an alternative measurement of our operating performance to net income. We believe that FFO is a beneficial indicator of the performance of an equity REIT. However, other REITs may not define FFO in accordance with the NAREIT definition, or may interpret the current NAREIT definition differently than we do; therefore, our computation of FFO may not be comparable to that of such other REITs.

Core Funds From Operations ("Core FFO"):We calculate Core FFO by starting with FFO, as defined by NAREIT, and adjusting for certain non-recurring items such as gains or losses on the early extinguishment of debt, acquisition-related costs and other significant non-recurring items. Such items create significant earnings volatility. We believe Core FFO provides a meaningful measure of our operating performance and more predictability regarding future earnings potential. Core FFO is a non-GAAP financial measure and should not be viewed as an alternative measurement of our operating performance to net income; therefore, it should not be compared to other REITs' equivalent to Core FFO.

Adjusted Funds From Operations ("AFFO"):AFFO is calculated by deducting from Core FFO non-incremental capital expenditures and acquisition-related costs and adding back non-cash items including non-real estate depreciation, straight lined rents and fair value lease revenue, non-cash components of interest expense and compensation expense, and by making similar adjustments for unconsolidated partnerships and joint ventures. Although AFFO may not be comparable to that of other REITs, we believe it provides a meaningful indicator of our ability to fund cash needs and to make cash distributions to equity owners. AFFO is a non-GAAP financial measure and should not be viewed as an alternative measurement of our operating performance to net income, as an alternative to net cash flows from operating activities or as a measure of our liquidity.

*Definitions

Core EBITDA: Core EBITDA is defined as net income before interest, taxes, depreciation and amortization and incrementally removing any impairment losses, gains or losses from sales of property, or other significant non-recurring items. We do not include impairment losses in this measure because we feel these types of losses create volatility in our earnings and make it difficult to determine the earnings generated by our ongoing business. We believe Core EBITDA is a reasonable measure of our liquidity. Core EBITDA is a non-GAAP financial measure and should not be viewed as an alternative measurement of cash flows from operating activities or other GAAP basis liquidity measures. Other REITs may calculate Core EBITDA differently and our calculation should not be compared to that of other REITs.

Property Net Operating Income (cash basis) ("Property NOI"):Property NOI is defined as real estate operating income with the add-back of corporate general and administrative expense, depreciation and amortization, and impairment losses and the deduction of income and expense associated with lease terminations and income associated with property management performed by Piedmont for other organizations. We present this measure on a cash basis, which eliminates the effects of straight lined rents and fair value lease revenue. The company uses this measure to assess its operating results and believes it is important in assessing operating performance. Property NOI is a non-GAAP measure which does not have any standard meaning prescribed by GAAP and therefore may not be comparable to similar measures presented by other companies.

Same Store Net Operating Income ("Same Store NOI"):Same Store NOI is calculated as the Core NOI attributable to the properties owned or placed in service during the entire span of the current and prior year reporting periods. Same Store NOI excludes amounts attributable to industrial properties and unconsolidated joint venture assets. We present this measure on an accrual basis and a cash basis, which eliminates the effects of straight lined rents and fair value lease revenue. We believe Same Store NOI is an important measure of comparison of our properties' operating performance from one period to another. Other REITs may calculate Same Store NOI differently and our calculation should not be compared to that of other REITs.
