Notes to Condensed Consolidated Financial Statements (Unaudited)

1. Organization, Basis of Presentation and Significant Accounting Policies

Gladstone Commercial Corporation is a real estate investment trust, or REIT, that was incorporated under the General Corporation Laws of the State of Maryland on February 14, 2003, primarily for the purpose of investing in and owning net leased industrial, commercial and retail real property and selectively making long-term industrial and commercial mortgage loans. Subject to certain restrictions and limitations, our business is managed by Gladstone Management Corporation, a Delaware corporation, or the Adviser, and administrative services are provided by Gladstone Administration, LLC, a Delaware limited liability company, or the Administrator, each pursuant to a contractual arrangement with us. Our Adviser and Administrator collectively employ all of our personnel and pay their salaries, benefits, and general expenses directly.

All further references herein to “we,” “our,” “us” and the “Company” mean Gladstone Commercial Corporation and its consolidated subsidiaries, except where it is made clear that the term means only Gladstone Commercial Corporation. All references to the number of properties and square footage are unaudited.

Subsidiaries

Gladstone Commercial Corporation conducts substantially all of its operations through a subsidiary, Gladstone Commercial Limited Partnership, a Delaware limited partnership, or the Operating Partnership. As Gladstone Commercial Corporation currently owns all of the general and limited partnership interests of the Operating Partnership through two of its subsidiaries, GCLP Business Trust I and II, the financial position and results of operations of the Operating Partnership are consolidated within Gladstone Commercial Corporation’s financial statements.

GCLP Business Trust I and GCLP Business Trust II, each a subsidiary and business trust of Gladstone Commercial Corporation, were formed under the laws of the Commonwealth of Massachusetts on December 28, 2005. Gladstone Commercial Corporation transferred its 99% limited partnership interest in the Operating Partnership to GCLP Business Trust I in exchange for 100 shares of the trust. Gladstone Commercial Partners, LLC transferred its 1% general partnership interest in the Operating Partnership to GCLP Business Trust II in exchange for 100 trust shares.

Gladstone Commercial Lending, LLC, a Delaware limited liability company, or Gladstone Commercial Lending, a subsidiary of Gladstone Commercial Corporation, was created to conduct all operations related to Gladstone Commercial Corporation’s real estate mortgage loans. As the Operating Partnership currently owns all of the membership interests of Gladstone Commercial Lending, the financial position and results of operations of Gladstone Commercial Lending are consolidated with Gladstone Commercial Corporation.

Gladstone Commercial Advisers, Inc., a Delaware corporation, or Commercial Advisers, and a wholly-owned subsidiary of Gladstone Commercial Corporation, is a taxable REIT subsidiary, or TRS, which was created to collect any non-qualifying income related to our real estate portfolio. There has been no such income earned to date. Since Gladstone Commercial Corporation owns 100% of the voting securities of Commercial Advisers, the financial position and results of operations of Commercial Advisers are consolidated within Gladstone Commercial Corporation’s financial statements.

Interim Financial Information

Our interim financial statements are prepared in accordance with U.S. generally accepted accounting principles, or GAAP, for interim financial information and pursuant to the requirements for reporting on Form 10-Q and in accordance with Article 10 of Regulation S-X. Accordingly, certain disclosures accompanying annual financial statements prepared in accordance with GAAP are omitted. The year-end balance sheet data presented herein was derived from audited financial statements, but does not include all disclosures required by GAAP. In the opinion of our management, all adjustments, consisting solely of normal recurring accruals, necessary for the fair presentation of financial statements for the interim period, have been included. The interim financial statements and notes thereto should be read in conjunction with the financial statements and notes thereto included in our Form 10-K for the year ended December 31, 2014, as filed with the U.S. Securities and Exchange Commission on February 18, 2015. The results of operations for the three months ended March 31, 2015 are not necessarily indicative of the results that may be expected for other interim periods or for the full fiscal year.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could materially differ from those estimates.

Real Estate and Lease Intangibles

We record investments in real estate at cost and capitalize improvements and replacements when they extend the useful life or improve the efficiency of the asset. We expense costs of repairs and maintenance as such costs are incurred. We compute depreciation using the straight-line method over the estimated useful life, or 39 years, for buildings and improvements, 5 to 20 years for equipment and fixtures, and the shorter of the useful life or the remaining lease term for tenant improvements and leasehold interests.

Certain of our acquisitions involve sale-leaseback transactions with newly-originated leases, which we account for as asset acquisitions under Accounting Standards Codification, or ASC, 805, “Business Combinations.” In the case of an asset acquisition, we will capitalize the transaction costs incurred in connection with the acquisition. Other of our acquisitions involve the acquisition of properties that are already being operated as rental properties, which we will generally consider to be a business combination under ASC 805. Business combination guidance is generally applicable to us when properties are acquired with leases in place at the time of acquisition. When an acquisition is considered a business combination, ASC 805 requires that the purchase price of real estate be allocated to the acquired tangible assets and liabilities, consisting of land, building, tenant improvements, long-term debt assumed and identified intangible assets and liabilities, typically the value of above-market and below-market leases, the value of in-place leases, the value of unamortized lease origination costs and the value of tenant relationships, based in each case on their fair values. ASC 805 also requires that all expenses related to an acquisition accounted for as a business combination to be expensed as incurred, rather than capitalized into the cost of the acquisition.

Management’s estimates of fair value are made using methods similar to those used by independent appraisers (e.g. discounted cash flow analysis). Factors considered by management in its analysis include an estimate of carrying costs during hypothetical expected lease-up periods considering current market conditions and costs to execute similar leases. We also consider information obtained about each property as a result of our pre-acquisition due diligence, marketing and leasing activities in estimating the fair value of the tangible and intangible assets acquired and liabilities assumed. In estimating carrying costs, management also includes lost reimbursement of real estate taxes, insurance and other operating expenses as well as estimates of lost rentals at market rates during the hypothetical expected lease-up periods, which primarily range from 9 to 18 months, depending on specific local market conditions. Management also estimates costs to execute similar leases, including leasing commissions, legal and other related expenses to the extent that such costs are not already incurred in connection with a new lease origination as part of the transaction.

Table of Contents

We allocate purchase price to the fair value of the tangible assets of an acquired property by valuing the property as if it were vacant. The “as-if-vacant” value is allocated to land, building and tenant improvements based on management’s determination of the relative fair values of these assets on the date of acquisition. Real estate depreciation expense on these tangible assets was $5.2 million and $4.4 million for the three months ended March 31, 2015 and 2014, respectively.

Above-market and below-market in-place lease fair values for owned properties are recorded based on the present value (using an interest rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of the lease. When determining the non-cancelable term of the lease, we evaluate which fixed-rate renewal options, if any, should be included. The capitalized above-market lease values, included in the accompanying condensed consolidated balance sheets as part of deferred rent receivable, are amortized as a reduction of rental income over the remaining non-cancelable terms of the respective leases. Total amortization related to above-market lease values was $0.1 million, for both the three months ended March 31, 2015 and 2014, respectively. The capitalized below-market lease values, included in the accompanying condensed consolidated balance sheets as part of deferred rent liability, are amortized as an increase to rental income over the remaining non-cancelable terms of the respective leases, including any below market renewal periods. Total amortization related to below-market lease values was $0.2 million, for both the three months ended March 31, 2015 and 2014, respectively.

The total amount of the remaining intangible assets acquired, which consists of in-place lease values, unamortized lease origination costs, and customer relationship intangible values, are allocated based on management’s evaluation of the specific characteristics of each tenant’s lease and our overall relationship with that respective tenant. Characteristics to be considered by management in determining these values include the nature and extent of our existing business relationships with the tenant, growth prospects for developing new business with the tenant, the tenant’s credit quality and our expectations of lease renewals (including those existing under the terms of the lease agreement), among other factors.

The value of in-place leases and lease origination costs are amortized to expense over the remaining term of the respective leases, which generally range from 10 to 15 years. The value of customer relationship intangibles, which is the benefit to us resulting from the likelihood of an existing tenant renewing its lease, are amortized to expense over the remaining term and any anticipated renewal periods in the respective leases, but in no event does the amortization period for intangible assets exceed the remaining depreciable life of the building. Total amortization expense related to these intangible assets and liabilities was $3.0 million and $2.3 million for the three months ended March 31, 2015 and 2014, respectively.

Should a tenant terminate its lease, the unamortized portion of the above-market and below-market lease values would be charged to rental income and the unamortized portion of in-place lease values, lease origination costs and customer relationship intangibles would be immediately charged to amortization expense.

Real Estate Held for Sale and Discontinued Operations

ASC 360-10, “Property, Plant, and Equipment,” requires that any properties which are held for sale, be presented separately in the condensed consolidated balance sheet. Real estate assets held for sale are measured at the lower of the carrying amount or the fair value, less the cost to sell, and are listed separately on our condensed consolidated balance sheet. Once properties are classified as held for sale, no further depreciation is recorded.

Under Accounting Standards Update No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity,” only disposals representing a strategic shift in operations, such as a disposal of a major geographic area, a major line of business, or a major equity method investment, will be presented as discontinued operations. We evaluated our held for sale assets according to this criteria, and determined we were not required to present our assets classified as held for sale during the quarter ended March 31, 2015 as discontinued operations.

Impairment Charges

We account for the impairment of real estate, including intangible assets, in accordance with ASC 360-10-35, “Property, Plant, and Equipment,” which requires us to periodically review the carrying value of each property to determine if circumstances indicate whether impairment of the carrying value of the investment exists or that depreciation periods should be modified. If circumstances indicate the possibility of impairment, we prepare a projection of the undiscounted future cash flows, without interest charges, of the specific property and determine if the carrying value of the investment in such property is recoverable. In performing the analysis, we consider such factors as each tenant’s payment history and financial condition, the likelihood of lease renewal, business conditions in the industry in which the tenants operate, whether there are indications that the fair value of the real estate has decreased and our intended holding period of the property. If the carrying amount is more than the aggregate undiscounted future cash flows, we would recognize an impairment loss to the extent the carrying amount exceeds the estimated fair value of the property.

We evaluate our entire portfolio of properties each quarter for any impairment indicators and perform an impairment analysis on those select properties that have an indication of impairment. We performed this evaluation and analysis and concluded that none of our properties were impaired as of March 31, 2015; however, we determined that our property located in Dayton, Ohio is at risk to become impaired in the future. The lease with the tenant in this property terminates on June 30, 2015. There is a possibility we may have to impair this property during 2015 if we do not find a replacement tenant.

Deferred Financing Costs

Deferred financing costs consist of costs incurred to obtain financing, including legal fees, origination fees and administrative fees. The costs are deferred and amortized using the straight-line method, which approximates the effective interest method, over the term of the secured financing. We made payments of $0.2 million and $0.4 million for deferred financing costs during the three months ended March 31, 2015 and 2014, respectively. Total amortization expense related to deferred financing costs is included in interest expense and was $0.4 million, for both the three months ended March 31, 2015 and 2014, respectively.

Revenue Recognition

Rental revenue includes rents that each tenant pays in accordance with the terms of its respective lease reported evenly over the non-cancelable term of the lease. Most of our leases contain rental increases at specified intervals. We recognize such revenues on a straight-line basis. Deferred rent receivable in the accompanying condensed consolidated balance sheet includes the cumulative difference between rental revenue, as recorded on a straight-line basis, and rents received from the tenants in accordance with the lease terms, along with the capitalized above-market or in-place lease values of certain acquired properties. Accordingly, we determine, in our judgment, to what extent the deferred rent receivable applicable to each specific tenant is collectable. We review deferred rent receivable, as it relates to straight line rents, on a quarterly basis and take into consideration the tenant’s payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the geographic area in which the property is located. In the event that the collectability of deferred rent with respect to any given tenant is in doubt, we record an allowance for uncollectable accounts or record a direct write-off of the specific rent receivable. No such reserves or direct write offs were recorded during the three months ended March 31, 2015, and 2014, respectively.

Tenant recovery revenue includes payments from tenants as reimbursements for franchise taxes, management fees, insurance, maintenance and repairs, utilities, and ground lease payments. We recognize tenant recovery revenue in the same periods that we incur the related expenses.

Mortgage Note Receivable

Management considers its loans and other lending investments to be held-for-investment. We reflect our loans classified as long-term investments at amortized cost, less allowance for loan losses, acquisition premiums or discounts, and deferred loan fees. On occasion, we may acquire loans at small premiums or discounts based on the credit characteristics of such loans. These premiums or discounts would be recognized as yield adjustments over the lives of the related loans. Loan origination fees, as well as direct loan origination costs, are also deferred and recognized over the lives of the related loans as yield adjustments. If loans with premiums, discounts, or loan origination fees are prepaid, we would immediately recognize the unamortized portion as a decrease or increase in the prepayment gain or loss. Interest income is recognized using the effective interest method applied on a loan-by-loan basis. Prepayment penalties or yield maintenance payments from borrowers are recognized as additional income when received.

Asset Retirement Obligations

ASC 410, “Asset Retirement and Environmental Obligation,” requires an entity to recognize a liability for a conditional asset retirement obligation when incurred if the liability can be reasonably estimated. ASC 410-20-20 clarifies that the term “Conditional Asset Retirement Obligation” refers to a legal obligation (pursuant to existing laws or by contract) to perform an asset retirement activity in which the timing and/or method of settlement are conditional on a future event that may or may not be within the control of the entity. ASC 410-20-25-6 clarifies when an entity would have sufficient information to reasonably estimate the fair value of an asset retirement obligation. We have accrued a liability at the present value of the estimated payments expected to be made and corresponding increase to the cost of the related properties for disposal related to all properties constructed prior to 1985 that have, or may have, asbestos present in the building. The liabilities are accreted to their estimated obligation over the life of the leases for the respective properties. We accrued approximately $20,000 in liabilities in connection with acquisitions during the three months ended March 31, 2015. There were no liabilities accrued during the three months ended March 31, 2014. We recorded expense of $0.04 million and $0.03 million during the three months ended March 31, 2015 and 2014 respectively, to general and administrative expense. Costs of future expenditures for obligations are discounted to their present value. The aggregate undiscounted obligation on all properties is $9.4 million and the discount rates used in the calculations range from 2.5% to 7.6%. We do not expect to make any payments in conjunction with these obligations in each of the next five years.

Comprehensive Income (Loss)

For the three months ended March 31, 2015 and 2014, comprehensive income (loss) equaled net income (loss); therefore, a separate statement of comprehensive income (loss) is not included in the accompanying condensed consolidated financial statements.

Segment Reporting

We manage our operations on an aggregated, single segment basis for purposes of assessing performance and making operating decisions, and, accordingly, have only one reporting and operating segment.

Recently Issued Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers,” which supersedes or replaces nearly all GAAP revenue recognition guidance. The new guidance establishes a new control-based revenue recognition model, changes the basis for deciding when revenue is recognized over time or at a point in time and will expand disclosures about revenue. We are currently assessing the impact of ASU 2014-09. ASU 2014-09 is effective for annual reporting periods that begin after December 15, 2016 and interim periods within those years. Early adoption is not permitted.

In February 2015, the FASB issued ASU 2015-02, “Amendments to the Consolidation Analysis” (“ASU-2015-02”), which amends or supersedes the scope and consolidation guidance under existing GAAP. The new standard changes the way a reporting entity evaluates whether a) limited partnerships and similar entities should be consolidated, b) fees paid to decision makers or service provides are variable interests in

10

Table of Contents

a variable interest entity, or VIE, and c) variable interests in a VIE held by related parties require the reporting entity to consolidate the VIE. ASU 2015-02 also eliminates the VIE consolidation model based on majority exposure to variability that applied to certain investment companies and similar entities. We are currently assessing the impact of ASU 2015-02, which is effective for annual and interim reporting periods beginning after December 15, 2015. Early adoption is permitted.

In April 2015, the FASB issued ASU 2015-03, “Simplifying the Presentation of Debt Issuance Costs” (“ASU-2015-03”), which simplifies the presentation of debt issuance costs. We are currently assessing the impact of ASU 2015-03 and do not anticipate a material impact on our financial position, results of operations or cash flows from adopting this standard. ASU 2015-03 is effective for annual and interim reporting periods beginning after December 15, 2015. Early adoption is permitted.

2. Related-Party Transactions

Gladstone Management and Gladstone Administration

We are externally managed pursuant to contractual arrangements with our Adviser and our Administrator, which collectively employ all of our personnel and pay their salaries, benefits, and general expenses directly. Both our Adviser and Administrator are affiliates of ours, as their parent company is controlled by Mr. David Gladstone, our chairman and chief executive officer. We have an advisory agreement with our Adviser, or the Advisory Agreement, and an administration agreement with our Administrator, or the Administration Agreement. The management and administrative services and fees under the Advisory and Administration Agreements are described below. At March 31, 2015 and December 31, 2014, $1.7 million and $0.9 million, respectively, was collectively due to our Adviser and Administrator.

Advisory Agreement

The Advisory Agreement provides for an annual base management fee equal to 2% of our total stockholders’ equity, less the recorded value of any preferred stock and adjusted to exclude the effect of any unrealized gains, losses or other items that do not affect realized net income (including impairment charges), or common stockholders’ equity, and an incentive fee based on funds from operations, or FFO. For the three months ended March 31, 2015 and 2014, we recorded a base management fee of $0.9 million, and $0.6 million, respectively.

For purposes of calculating the incentive fee, FFO includes any realized capital gains and capital losses, less any distributions paid on preferred stock and Senior Common Stock, but FFO does not include any unrealized capital gains or losses (including impairment charges). The incentive fee rewards the Adviser if our quarterly FFO, before giving effect to any incentive fee, or pre-incentive fee FFO, exceeds 1.75%, or 7% annualized, or the hurdle rate, of total common stockholders’ equity. The Adviser receives 100% of the amount of the pre-incentive fee FFO that exceeds the hurdle rate, but is less than 2.1875% of our common stockholders’ equity. The Adviser also receives an incentive fee of 20% of the amount of our pre-incentive fee FFO that exceeds 2.1875% of common stockholders’ equity.

For the three months ended March 31, 2015, and 2014, we recorded an incentive fee of $1.7 million, and $1.2 million, respectively, offset by credits related to unconditional, voluntary and irrevocable waivers issued by the Adviser of $1.2 million and $1.2 million, respectively, resulting in a net incentive fee for the three months ended March 31, 2015, and 2014, of $0.5 million, and $40,000, respectively. Our Board of Directors accepted the Adviser’s offer to waive, on a quarterly basis, a portion of the incentive fee for the three months ended March 31, 2015, and 2014, in order to support the current level of distributions to our stockholders. This waiver may not be recouped by the Adviser in the future.

Administration Agreement

Pursuant to the Administration Agreement, we pay for our allocable portion of the Administrator’s expenses in performing services to us, including, but not limited to, rent and the salaries and benefits of its personnel, including our chief financial officer, treasurer, chief compliance officer, general counsel and secretary (who also serves as our Administrator’s president), and their respective staffs. Prior to July 1, 2014,

11

Table of Contents

our allocable portion was generally derived by multiplying that portion of the Administrator’s expenses allocable to all funds managed by the Adviser by the percentage of our total assets at the beginning of each quarter in comparison to the total assets of all funds managed by the Adviser. As approved by our Board of Directors, effective July 1, 2014, our allocable portion of the Administrator’s expenses is derived by multiplying our Administrator’s total expenses by the approximate percentage of time the Administrator’s employees perform services for us in relation to their time spent performing services for all companies serviced by our Administrator under contractual agreements. For the three months ended March 31, 2015, and 2014, we recorded an administration fee of $0.4 million, and $0.5 million, respectively.

Gladstone Securities

Gladstone Securities, LLC, or Gladstone Securities, is a privately held broker dealer registered with the Financial Industry Regulatory Authority and insured by the Securities Investor Protection Corporation. Gladstone Securities is an affiliate of ours, as its parent company is controlled by Mr. David Gladstone, our chairman and chief executive officer. Mr. Gladstone also serves on the board of managers of Gladstone Securities.

Dealer Manager Agreement

In connection with the offering of our Senior Common Stock (see Note 10, “Stockholders’ Equity,” for further details) we entered into a Dealer Manager Agreement, dated March 25, 2011, or the Dealer Manager Agreement, with Gladstone Securities pursuant to which Gladstone Securities agreed to act as our exclusive dealer manager in connection with the offering. Pursuant to the terms of the Dealer Manager Agreement, Gladstone Securities was entitled to receive a sales commission in the amount of 7.0% of the gross proceeds of the shares of Senior Common Stock sold, plus a dealer manager fee in the amount of 3.0% of the gross proceeds of the shares of Senior Common Stock sold. Gladstone Securities, in its sole and absolute discretion, was permitted to re-allocate all of its selling commissions attributable to a participating broker-dealer and also re-allocate a portion of its dealer manager fee earned in respect of the proceeds generated by the participating broker-dealer to any participating broker-dealer as a non-accountable marketing allowance. In addition, we agreed to indemnify Gladstone Securities against various liabilities, including certain liabilities arising under the federal securities laws. We made approximately $0.3 million, and $40,000 of payments during the three months ended March 31, 2015, and 2014 respectively, to Gladstone Securities pursuant to this agreement, which are reflected as a component of Senior Common Stock costs in the condensed consolidated statement of stockholders’ equity. The Dealer Manager Agreement terminated according to its terms on March 28, 2015, and we wrote-off $0.1 million of deferred offering costs related to the termination of the agreement to general and administrative expense.

Mortgage Financing Arrangement Agreement

We also entered into an agreement with Gladstone Securities, effective June 18, 2013, for it to act as our non-exclusive agent to assist us with arranging mortgage financing for properties we own. In connection with this engagement, Gladstone Securities may from time to time solicit the interest of various commercial real estate lenders or recommend to us third party lenders offering credit products or packages that are responsive to our needs. We pay Gladstone Securities a financing fee in connection with the services it provides to us for securing mortgage financing on any of our properties. The amount of these financing fees, which are payable upon closing of the financing, are based on a percentage of the amount of the mortgage, generally ranging from 0.15% to a maximum of 1.0% of the mortgage obtained. The amount of the financing fees may be reduced or eliminated, as determined by us and Gladstone Securities, after taking into consideration various factors, including, but not limited to, the involvement of any third party brokers and market conditions. We paid financing fees to Gladstone Securities of $38,000 during the three months ended March 31, 2015, which are reflected as deferred financing costs in the condensed consolidated balance sheets, on total mortgages secured of $14.6 million, or 0.26%. We did not pay any financing fees to Gladstone Securities during the three months ended March 31, 2014. The agreement is scheduled to terminate on August 31, 2015, unless renewed or earlier terminated pursuant to the provisions contained therein.

3. Loss per Share of Common Stock

The following tables set forth the computation of basic and diluted loss per share of common stock for each of the three months ended March 31, 2015 and 2014. We computed basic loss per share for the three months ended March 31, 2015 and 2014 using the weighted average number of shares outstanding during the periods. Diluted loss per share for the three months ended March 31, 2015 and 2014, reflects additional shares of common stock related to our convertible Senior Common Stock (if the effect would be dilutive), that would have been outstanding if dilutive potential shares of common stock had been issued, as well as an adjustment to net income available to common stockholders as applicable to common stockholders that would result from their assumed issuance (dollars in thousands, except per share amounts).

Significant Real Estate Activity on Existing Assets

On January 29, 2015, we modified leases with two tenants occupying space in our Indianapolis, Indiana property. One tenant, occupying 3,546 square feet, extended its lease term for an additional seven years, through March 2023. The original lease term would have expired in February 2016. This lease contains prescribed rent escalations over its life with annualized straight line rents of approximately $0.06 million, unchanged from the previous lease. In connection with the extension of the lease and modification of certain of its terms, we provided $0.06 million in tenant improvements. The other tenant, previously occupying 7,639 square feet, added an additional suite to its lease, increasing its leased square footage to 8,275. The lease expiration date is unchanged at January 2018. The new lease contains prescribed rent escalations over the life of the lease with annualized straight line rents of approximately $0.1 million, a slight increase over the previous lease.

On February 9, 2015, we modified the leases with the tenant occupying two of our properties, both located in Raleigh, North Carolina. The leases covering these properties were extended for an additional five years each, through July 2020. Both leases were originally set to expire in July 2015. The tenant was previously fully occupying both buildings, totaling 174,426 square feet, but had reduced its space requirement in the industrial building by 94,200 square feet. Both leases contain prescribed rent escalations over the life of the lease, with annualized straight line rents of approximately $0.9 million, as compared to annualized straight line rents of $1.3 million under the previous terms of the lease. The tenant has two options to renew both leases for an additional period of five years each. In connection with the extension of the lease and modification of certain terms of the lease, we paid $0.2 million in leasing commissions, and paid $0.1 million in tenant improvements.

On February 20, 2015, we entered into a purchase and sale agreement with a third party to acquire our Columbus, Ohio property for $2.8 million, which is greater than the current carrying value of the property of $2.4 million. The lease on this property is scheduled to terminate in October 2015 and the current tenant has notified us of its plan to vacate. We anticipate the sale to be completed in November 2015. We considered this asset to be non-core to our long term strategy, and we will re-deploy the proceeds from this sale into future acquisitions.

On February 27, 2015, we modified the lease with the tenant occupying our property located in San Antonio, Texas. The modification provided the tenant a termination option, which allows the tenant to terminate its lease effective December 31, 2017, upon paying a termination penalty of approximately $1.0 million on or before March 31, 2017. All other terms and conditions of the lease remain in full force and effect.

5. Real Estate Held for Sale

Real Estate Held for Sale

As of March 31, 2015, we classified one of our properties located in Columbus, Ohio as held for sale under the provisions of ASC 360-10, which requires that the assets and liabilities of any such properties, be presented separately in our condensed consolidated balance sheet in the current period presented. We executed a purchase and sale agreement with the third party purchaser, and we anticipate the sale to close during November 2015. The agreed upon purchase price, net of expected costs to sell, is in excess of the carrying value of the property as of March 31, 2015, and thus the property was measured at its carrying value in our condensed consolidated balance sheet as of March 31, 2015 in accordance with ASC 360-10.

6. Mortgage Note Receivable

On July 25, 2014, we closed a $5.6 million second mortgage development loan for the construction of an 81,371 square foot, build-to-suit transitional care facility located on a major hospital campus in Phoenix, Arizona. Construction is scheduled to be completed in September 2015 and we will earn 9.0% interest, paid currently in cash, on the loan during construction and through maturity. Prior to completion of the facility, we will be granted a right of first offer to purchase the property at fair value. If we do not purchase the property we will receive an exit fee upon maturity of the loan in an amount sufficient for us to earn an internal rate of return of 22% on the second mortgage development loan, inclusive of interest earned. The loan is scheduled to mature in July 2016, but has a one-year extension option. We have recognized approximately $0.3 million in both cash interest income and accrued exit fee revenue during the three months ended March 31, 2015.

Our mortgage notes payable and line of credit as of March 31, 2015 and December 31, 2014 are summarized below (dollars in thousands):

N/A—Not Applicable

Mortgage Notes Payable

As of March 31, 2015, we had 42 mortgage notes payable, collateralized by a total of 78 properties and the net book value of these collateralized properties was $669.6 million. Gladstone Commercial Corporation has limited recourse liabilities that could result from any one or more of the following circumstances: a borrower voluntarily filing for bankruptcy, improper conveyance of a property, fraud or material misrepresentation, misapplication or misappropriation of rents, security deposits, insurance proceeds or condemnation proceeds, or physical waste or damage to the property resulting from a borrower’s gross negligence or willful misconduct. We will also indemnify lenders against claims resulting from the presence of hazardous substances or activity involving hazardous substances in violation of environmental laws on a property. The weighted-average interest rate on the mortgage notes payable as of March 31, 2015 was 5.26%.

During the three months ended March 31, 2015, we issued one long-term mortgage, collateralized by a single property, which is summarized below (dollars in thousands):

Scheduled principal payments of mortgage notes payable for the remainder of 2015, and each of the five succeeding fiscal years and thereafter are as follows (dollars in thousands):

Interest Rate Cap

We have entered into an interest rate cap agreement with Wells Fargo that caps the interest rate on the note payable for our Champaign, Illinois property at a certain interest rate when one-month LIBOR is in excess of 3.0%. The fair value of the interest rate cap agreement is recorded in Other assets on our accompanying condensed consolidated balance sheets. We record changes in the fair value of the interest rate cap agreement quarterly based on the current market valuations at quarter end as Other income (loss) on our accompanying condensed consolidated statements of operations. Generally, we will estimate the fair value of our interest rate cap using estimates of value provided by the counterparty and our own assumptions in the absence of observable market data, including estimated remaining life, counterparty credit risk, current market yield and interest rate spreads of similar securities as of the measurement date. At March 31, 2015 and December 31, 2014, our interest rate cap agreement was valued using Level 3 inputs. The following table summarizes the key terms of each interest rate cap agreement (dollars in thousands):

Fair Value

The fair value of all mortgage notes payable outstanding as of March 31, 2015, excluding mortgage notes payable on real estate held for sale, was $485.2 million, as compared to the carrying value stated above of $469.0 million. The fair value is calculated based on a discounted cash flow analysis, using interest rates based on management’s estimate of market interest rates on long-term debt with comparable terms and loan to value ratios. The fair value was calculated using Level 3 inputs of the hierarchy established by ASC 820, “Fair Value Measurements and Disclosures.”

Line of Credit

In August 2013, we procured a $60.0 million senior unsecured revolving credit facility, or the Line of Credit, which was expanded to $75.0 million in November 2014, with KeyBank National Association (serving as a revolving lender, a letter of credit issuer and an administrative agent) and added Citizens Bank of Pennsylvania as an additional lender. Comerica Bank was subsequently added as another lender in

Table of Contents

December 2013. In March 2014, we amended our Line of Credit to extend the maturity date by one year to August 2017. We also modified certain terms under the Line of Credit, including the calculation of the total asset value and unencumbered asset value. The applicable LIBOR margins were also reduced 25 basis points at each pricing level. As a result of these modifications, the availability under our Line of Credit increased by $1.3 million.

The Line of Credit initially matures in August 2017; however, we have a one-year extension option subject to the payment of an extension fee equal to 25 basis points on the initial maturity date and certain other customary conditions.

The Line of Credit has a letter of credit sublimit of up to $20.0 million. In addition, we may expand the Line of Credit up to a total of $100.0 million upon satisfaction of certain conditions and payment of the associated up front and arrangement fees at the time of such increase. The interest rate per annum applicable to the Line of Credit is equal to the London Interbank Offered Rate, or LIBOR, plus an applicable margin of up to 3.25%, depending upon our leverage. The leverage ratio used in determining the applicable margin for interest on the Line of Credit is recalculated quarterly. We are subject to an annual maintenance fee of $0.03 million per year and an unused commitment fee of 25 basis points per year, which accrues quarterly. Our ability to access this source of financing is subject to our continued ability to meet customary lending requirements, such as compliance with financial and operating covenants and our meeting certain lending limits. One such covenant requires us to limit distributions to our stockholders to 100% of our FFO, with acquisition-related costs required to be expensed under ASC 805 added back to FFO. In addition, the maximum amount we may draw under the Line of Credit is based on a percentage of the value of a pool of unencumbered properties, which must meet agreed upon eligibility standards.

If and when long-term mortgages are arranged for properties in the unencumbered pool, the banks will reduce the availability under the Line of Credit by the amount advanced against that property’s value. Conversely, as we purchase new properties meeting the eligibility standards, we may add these new properties to the unencumbered pool to obtain additional availability under the Line of Credit. The availability under the Line of Credit is also reduced by letters of credit used in the ordinary course of business. We may use the advances under the Line of Credit for both general corporate purposes and the acquisition of new investments.

As of March 31, 2015, there was $41.3 million outstanding under our Line of Credit at an interest rate of approximately 2.93% and $4.5 million outstanding under letters of credit at a weighted average interest rate of 2.75%. As of May 4, 2015, the maximum additional amount we could draw was $18.9 million. We were in compliance with all covenants under the Line of Credit as of March 31, 2015.

8. Mandatorily Redeemable Preferred Stock

In February 2012, we completed a public offering of 1,540,000 shares of 7.125% Series C Cumulative Term Preferred Stock, par value $0.001 per share, or the Term Preferred Stock, at a public offering price of $25.00 per share. Gross proceeds of the offering totaled $38.5 million and net proceeds, after deducting offering expenses borne by us, were $36.7 million and were used to repay a portion of outstanding borrowings under our Line of Credit, for acquisitions of real estate and for working capital. The Term Preferred Stock is traded under the ticker symbol GOODN on the NASDAQ Global Select Market, or the NASDAQ. The Term Preferred Stock is not convertible into our common stock or any other security of ours. Generally, we may not redeem shares of the Term Preferred Stock prior to January 31, 2016, except in limited circumstances to preserve our status as a REIT. On or after January 31, 2016, we may redeem the shares at a redemption price of $25.00 per share, plus any accumulated and unpaid dividends to and including the date of redemption. The shares of the Term Preferred Stock have a mandatory redemption date of January 31, 2017. We incurred $1.8 million in total offering costs related to these transactions, which have been recorded as deferred financing costs on the condensed consolidated balance sheet and will be amortized through interest expense over the redemption period ending January 31, 2017.

The Term Preferred Stock is recorded as liability in accordance with ASC 480, “Distinguishing Liabilities from Equity,” which states that mandatorily redeemable financial instruments should be classified as liabilities and therefore the related dividend payments are treated as a component of interest expense in the condensed consolidated statements of operations.

Table of Contents

The fair value of our Term Preferred Stock as of March 31, 2015, was $39.9 million, as compared to the carrying value stated above of $38.5 million. The fair value is calculated based on the closing share price as of March 31, 2015 of $25.92. The fair value was calculated using Level 1 inputs of the hierarchy established by ASC 820, “Fair Value Measurements and Disclosures.”

Ongoing Activity

On September 2, 2014 we entered into an open market sale agreement, or the ATM Program, with Cantor Fitzgerald & Co., or Cantor Fitzgerald, pursuant to which we may, from time to time, offer to sell shares of our common stock with an aggregate sales price of up to $100.0 million on the open market through Cantor Fitzgerald, acting as sales agent and/or principal. During the three months ended March 31, 2015, we raised approximately $15.1 million in net proceeds under the ATM Program. As of March 31, 2015, under the existing program, we have sold a total of 2.7 million shares with aggregate gross proceeds of $47.8 million, and have a remaining capacity to sell up to $52.2 million of common stock under the ATM Program with Cantor Fitzgerald.

In March 2011, we commenced an offering of an aggregate of 3,500,000 shares of our Senior Common Stock, par value $0.001 per share, at a price to the public of $15.00 per share, of which 3,000,000 shares were intended to be offered pursuant to the primary offering and 500,000 shares were intended to be offered pursuant to our senior common distribution reinvestment plan, or the DRIP. We elected not to extend this offering, which terminated according to its terms on March 28, 2015. During the three months ended March 31, 2015, we sold 189,052 shares of our Senior Common Stock at $15.00 per share and issued 5,239 shares of our Senior Common Stock under the Dividend Reinvestment Plan, or DRIP, program. The net proceeds, after deducting the underwriting discount and commission, were $2.6 million. At the conclusion of the offering on March 28, 2015, we had sold 927,994 shares of Senior Common Stock, for gross proceeds of $13.9 million, and issued an additional 27,861 shares of Senior Common Stock under the DRIP program.

Note to Employee

The following table is a summary of the outstanding note issued to an employee of the Adviser for the exercise of stock options (dollars in thousands):

The employee stock option program terminated in 2006. In accordance with ASC 505-10-45-2, “Equity,” receivables from employees for the issuance of capital stock to employees prior to the receipt of cash payment should be reflected in the balance sheet as a reduction to stockholders’ equity. Therefore, this note was recorded as a full recourse loan to the employee and is included in the equity section of the accompanying condensed consolidated balance sheets. As of March 31, 2015, this loan maintained its full recourse status.

Phoenix, Arizona: On April 14, 2015, we closed a $0.3 million interim financing loan for the acquisition of land to be used for redevelopment and expansion of a medical center campus in Phoenix, Arizona. This loan is collateralized by proceeds from the sale of the transitional care facility for which we provided a mortgage development loan on July 25, 2014 (see Note 6). We will earn interest of 22% per annum through the maturity date, with all accrued interest and principal payable upon maturity. This loan matures upon the earlier of April 2016 or the sale of the transitional care facility, which is anticipated to occur in November 2015.

Austin, Texas: On April, 28 2015, we modified the lease with the tenant occupying one of our properties located in Austin, Texas. The modification provided the tenant a termination option, which allows the tenant to terminate its lease effective December 31, 2017, upon paying a termination penalty of approximately $1.1 million on or before March 31, 2017. This modification forfeits the tenant’s right to $0.6 million in tenant improvement allowance, provided in an earlier amendment. All other terms and conditions of the lease remain in full force and effect.

General

We are an externally-advised real estate investment trust, or REIT, that was incorporated under the General Corporation Law of the State of Maryland on February 14, 2003, primarily for the purpose of investing in and owning net leased industrial, commercial and retail real property and selectively making long-term industrial and commercial mortgage loans. Our portfolio of real estate is leased to a wide cross section of tenants ranging from small businesses to large public companies, many of which are corporations that do not have publicly-rated debt. We have historically entered into, and intend in the future to enter into, purchase agreements for real estate having triple net leases with terms of approximately 10 to 15 years and built in rental rate increases. Under a triple net lease, the tenant is required to pay all operating, maintenance and insurance costs and real estate taxes with respect to the leased property. We actively communicate with buyout funds, real estate brokers and other third parties to locate properties for potential acquisition or to provide mortgage financing in an effort to build our portfolio. We currently own 98 properties totaling 10.8 million square feet, which have a total gross and net carrying value, including intangible assets and properties held for sale, of $889.4 million and $749.1 million, respectively. We also currently have one mortgage loan receivable outstanding for $5.6 million.

Business Environment

The strength of the global economy and the U.S. economy in particular, continues to be uncertain and volatile, and we remain cautious about a long-term economic recovery. Vacancy rates have decreased for both office and industrial properties in most markets as increased user demand with restrained new construction activity has led to improved conditions. In fact, vacancy rates in many markets have been reduced to levels seen at the latest peak before the recession. Construction activity, particularly for industrial properties, is on the rise as a result of increased demand for facilities to satisfy the increased demand in the e-commerce sector. However, vacancy rates in certain secondary markets are still higher than pre-recession levels, as job growth has yet to return to all areas of the country even though the national unemployment rate has dropped over the past 12 months. Interest rates have decreased since the beginning of the year and remain at historic lows. This continued low interest rate environment is leading to increasing competition for new acquisitions. In addition, the uncertainty surrounding the ability of the federal government to address its fiscal condition in both the near and long term has increased domestic and

Table of Contents

global economic instability. These developments and our government’s credit concerns in general, could cause interest rates and borrowing costs to rise, which may negatively impact our ability to access both the debt and equity markets on favorable terms. In addition, a further decrease to the U.S. credit rating could create broader financial turmoil and uncertainty, which may weigh heavily on our stock price. Continued adverse economic conditions could have a material adverse effect on one or more of our tenants, or our business, financial condition and results of operations.

We continue to focus on re-leasing vacant space, renewing upcoming lease maturities and acquiring additional properties. Currently, we have two fully vacant buildings located in Baytown, Texas and Newburyport, Massachusetts and one partially vacant building located in Bolingbrook, Illinois. Our Baytown, Texas tenant vacated upon its lease termination in April 2013 and our Newburyport, Massachusetts tenant vacated upon its lease termination in April 2015. Our Bolingbrook, Illinois tenant vacated upon their lease termination in December 2014 and we have a partial space tenant for this property, which took occupancy in December 2014. We originally had 12 leases expiring in 2015, and we have successfully extended the leases for 7 of these tenants, one in negotiation with the current tenant, and one in which we agreed to sell the property to a third party. We have been notified that 3 of the 12 tenants will leave. We are aggressively pursuing new tenants for the 3 properties of which the tenants are vacating. These properties comprise less than 3% of our projected 2015 rental income, and 50% of this income does not terminate until December 2015. While we originally had 12 leases expiring in 2015, we only have 4 leases expiring in 2016, 6 in 2017 and 4 in 2018, which are each less than 2% of annualized rents for each respective year.

Our available vacant space at March 31, 2015 comprises less than 0.5% of our total square footage and the annual carrying costs are approximately $0.2 million. We continue to actively seek new tenants for these properties.

Our ability to make new investments is highly dependent upon our ability to procure external financing. Our principal sources of external financing generally include the issuance of equity securities, long-term mortgage loans secured by properties and borrowings under our line of credit, or the Line of Credit. The market for long-term mortgages continues to improve and long-term mortgages are readily obtainable. The collateralized mortgage backed securities, or CMBS, market remains active but it is more conservative and restrictive than it was prior to the recession and uncertainty with regard to interest rates has made the CMBS market less predictable. We continue to look to regional banks, insurance companies and other non-bank lenders, in addition to the CMBS market to issue mortgages to finance our real estate activities.

In addition to obtaining funds through borrowing, we have been active in the equity markets during 2015. We have issued shares of common stock through our at-the-market program, or ATM Program, pursuant to our open market sale agreement with Cantor Fitzgerald & Co., or Cantor Fitzgerald, discussed in more detail below. In addition, we have issued shares of our convertible senior common stock, or the Senior Common Stock, also discussed in more detail below.

Recent Developments

2015 Investment Activity

Richardson, Texas: On March 6, 2015, we acquired a 155,984 square foot office building located in Richardson, Texas for $24.7 million, excluding related acquisition expenses of $0.1 million. We funded this acquisition with existing cash on hand and the issuance of $14.6 million of mortgage debt on the property. The tenant has leased the property for 9.5 years and has 2 options to renew the lease for an additional 5 years each. The lease provides for prescribed rent escalations over the life of the lease, with annualized straight line gross rents of $2.7 million.

Birmingham, Alabama: On March 20, 2015, we acquired a 30,850 square foot office building located in Birmingham, Alabama for $3.6 million, excluding related acquisition expenses of $0.1 million. We funded this acquisition with existing cash on hand. The tenant has leased the property for 8.5 years and has 1 option to renew the lease for an additional 5 years. The lease provides for prescribed rent escalations over the life of the lease, with annualized straight line rents of $0.3 million.

Table of Contents

Phoenix, Arizona: On April 14, 2015, we closed a $0.3 million interim financing loan for the acquisition of land to be used for redevelopment and expansion of a medical center campus in Phoenix, Arizona. This loan is collateralized by proceeds from the sale of the transitional care facility for which we provided a mortgage development loan on July 25, 2014 (see Note 6 in footnotes to the financial statements). We will earn interest of 22% per annum through the maturity date, with all accrued interest and principal payable upon maturity. This loan matures upon the earlier of April 2016 or the sale of the transitional care facility, which is anticipated to occur in November 2015.

2015 Sale Activity

Columbus, Ohio: On February 20, 2015, we entered into a purchase and sale agreement with a third party to acquire our Columbus, Ohio property for $2.8 million, which is greater than the current carrying value of the property. The lease on this property is scheduled to terminate in October 2015 and the current tenant has notified us of its plan to vacate. We anticipate the sale to be completed in November 2015. We considered this asset to be non-core to our long term strategy, and we will re-deploy the proceeds from this sale into future acquisitions.

2015 Financing Activity

The following is a summary of our recent financings:

PNC Bank: On March 6, 2015, through a wholly-owned subsidiary, we borrowed $14.6 million pursuant to a long-term note payable from PNC Bank National Association, which is collateralized by a security interest in one of our properties. The note accrued interest at a fixed rate of 3.86% per year and has a maturity date of April 1, 2025. We used the proceeds from the note to acquire the property in Richardson, Texas on the same date.

2015 Leasing Activities

Indianapolis, Indiana: On January 29, 2015, we modified leases with two tenants occupying space in our Indianapolis, Indiana property. One tenant, occupying 3,546 square feet, extended its lease term for an additional seven years, through March 2023. The original lease would have expired in February 2016. This lease contains prescribed rent escalations over its life with annualized straight line rents of approximately $0.06 million, unchanged from the previous lease. In connection with the extension of the lease and modification of certain of its terms, we provided $0.06 million in tenant improvements. The other tenant, previously occupying 7,639 square feet, added an additional suite to its lease, increasing its leased square footage to 8,275. The lease expiration date is unchanged at January 2018. The new lease contains prescribed rent escalations over the life of the lease with annualized straight line rents of approximately $0.1 million, a slight increase over the previous lease.

Raleigh, North Carolina:

Raleigh, North Carolina: On February 9, 2015, we modified the leases with the tenant occupying two of our properties, both located in Raleigh, North Carolina. The leases covering these properties were extended for an additional five years each, through July 2020. Both leases were originally set to expire in July 2015. The tenant was previously fully occupying both buildings, totaling 174,426 square feet, but had reduced its space requirement in the industrial building by 94,200 square feet. Both leases contain prescribed rent escalations over the life of the lease, with annualized straight line rents of approximately $0.9 million, as compared to annualized straight line rents of $1.3 million under the previous terms of the lease. The tenant has two options to renew both leases for an additional period of five years each option. In connection with the extension of the lease and modification of certain terms of the lease, we paid $0.2 million in leasing commissions, and paid $0.1 million in tenant improvements.

San Antonio, Texas: On February 27, 2015, we modified the lease with the tenant occupying our property located in San Antonio, Texas. The modification provided the tenant a termination option, which allows the tenant to terminate their lease effective December 31, 2017, upon paying a termination penalty of approximately $1.0 million on or before March 31, 2017. All other terms and conditions of the lease remain in full force and effect.

Austin, Texas: On April, 28 2015, we modified the lease with the tenant occupying one of our properties located in Austin, Texas.

2015 Equity Activities

The equity issuances summarized below were issued under our universal shelf registration statement (File No. 333-190931) that was effective and on file with the Securities and Exchange Commission at the time of each respective issuance.

ATM Programs: During the three months ended March 31, 2015, we sold 0.9 million shares, raising an aggregate of $15.1 million in net proceeds under our ATM Program with Cantor Fitzgerald. Proceeds from these sales were used to acquire real estate, repay indebtedness and for other general corporate purposes. Under the ATM Program we may, from time to time, offer to sell shares of our common stock with an aggregate sales price of up to $100.0 million on the open market through Cantor Fitzgerald, as agent, or to Cantor Fitzgerald, as principal, based upon our instructions (including any price, time or size limits or other customary parameters or conditions that we may impose). We raised $47.1 million in net proceeds under the ATM Program from September 2014 to date. Sales of shares of our common stock through our ATM Program are executed by means of ordinary brokers’ transactions on the NASDAQ Global Select Market, or the NASDAQ, or otherwise at market prices, in privately negotiated transactions, crosses or block transactions, as may be agreed between us and Cantor Fitzgerald, including a combination of any of these transactions.

Senior Common Equity: During the three months ended March 31, 2015, we sold 189,052 shares of our Senior Common Stock at $15.00 per share and issued 5,239 shares of our Senior Common Stock under the Dividend Reinvestment Plan, or DRIP, program. The net proceeds, after deducting the underwriting discount and commission, were $2.6 million. This offering terminated according to its terms on March 28, 2015, and we wrote-off $0.1 million of deferred offering costs related to such termination. Proceeds from this offering were used to acquire real estate and for general corporate purposes.
