Report of Independent Auditors

To the shareholders of Gladstone Land Corporation

We have audited the accompanying Historical Statement of Revenues (the “Historical Statement”) of Espinosa Road (the “Property”) for the year ended December 31, 2014.

Management’s Responsibility for the Financial Statement

Management of Gladstone Land Corporation (the “Company”) is responsible for the preparation and fair presentation of the financial statement in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s Responsibility

Our responsibility is to express an opinion on the Historical Statement based on our audit. We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the Historical Statement is free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the Historical Statement. The procedures selected depend on our judgment, including the assessment of the risks of material misstatement of the Historical Statement, whether due to fraud or error. In making those risk assessments, we consider internal control relevant to the Company’s preparation and fair presentation of the Historical Statement in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the Historical Statement. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the Historical Statement referred to above presents fairly, in all material respects, the revenues, as described in Note 2, of the Property for the year ended December 31, 2014, in conformity with accounting principles generally accepted in the United States of America.

Other Matter

The accompanying Historical Statement was prepared for the purpose of complying with the rules and regulations of the Securities and Exchange Commission as described in Note 2 and is not intended to be a complete presentation of the Property’s revenues. Our opinion is not modified with respect to this matter.

Espinosa Road

Notes to Statement of Revenues

The accompanying historical statement of revenues relates to the operations of Espinosa Road (the “Property”), consisting of the revenue of one 331-acre farm located in Monterey County, California. Gladstone Land Corporation, through its wholly-owned operating partnership, Gladstone Land Limited Partnership (collectively, the “Company”), acquired the Property from an unaffiliated party on January 5, 2015, for total consideration of approximately $17.0 million.

The accompanying historical statement of revenues was prepared for the purpose of complying with Rule 3-14 of Regulation S-X, as promulgated by the Securities and Exchange Commission, in connection with the Company’s acquisition of the Property. The historical statement is not representative of the actual operations of the Property for the period presented, nor indicative of future operations; however, the Company is not aware of any material factors relating to the Property that would cause the reported financial information to not be indicative of future operating results. In addition, certain expenses, primarily amortization and interest expense, which may not be comparable to the expenses expected to be incurred by the Company in future operations of the Property, have been excluded. Additionally, the Company’s lease with the tenant is structured in such a way that the tenant is responsible for substantially all of the Property’s operating expenses. The Company does not expect to incur any significant operating expenses in the future operations of the Property, so those expenses have been excluded from this historical statement.

Revenue Recognition

The lease is accounted for as an operating lease, and revenue is recognized on a straight-line basis in accordance with the terms of the related lease.

Use of Estimates

The preparation of this historical statement in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amounts of revenue during the reporting period. Actual results may differ from these estimates.

On September 14, 2009, the Property entered into a 3-year lease agreement (the “Original Lease”) with a single tenant (the “Tenant”) for the entire Property. The Original Lease commenced on November 1, 2009, and was scheduled to expire on October 31, 2012. On September 19, 2012, the Property and the Tenant entered into an amendment to the Original Lease, which, among other things, extended the term by four years, to October 31, 2016 (the “Renewal Term”), and amended the amount of rent due during the Renewal Term.

As of December 31, 2014, aggregate future minimum rental payments to be received by the Property under the lease were as follows:

Major Tenant

During the year ended December 31, 2014, the Property’s total rental income of $750,265 was attributable to only one tenant.

The Company evaluated all events that have occurred subsequent to December 31, 2014, through March 6, 2015, the date the historical statement was issued.

GLADSTONE LAND CORPORATION

UNAUDITED PRO-FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

On January 5, 2015, Gladstone Land Corporation, through its wholly-owned operating partnership, Gladstone Land Limited Partnership (collectively with Gladstone Land Corporation, the “Company”), acquired a farm totaling approximately 331 gross acres located in Monterey County, California (the “Property”), for approximately $17.0 million, exclusive of acquisition-related costs of approximately $16,000. The Company funded this acquisition with $10.2 million of proceeds it received through a bond issuance under its facility with Federal Agricultural Mortgage Corporation and by drawing $8.0 million on its line of credit with Metropolitan Life Insurance Company. In evaluating the Property as a potential acquisition and determining the appropriate amount of consideration to be paid, the Company considered a variety of factors, including location, water and soil quality, credit quality of the tenant, terms of the in-place lease, comparative land values and comparative rents. At closing, the Company assumed the existing lease on the Property with a tenant that has leased the Property for over four years. The assumed lease expires on October 31, 2016, and provides for annualized, straight-line rents of $778,342. Had the Company acquired the Property on January 1, 2014, the remaining term of the lease would have provided for annualized, straight-line rents of $767,414.

The pro-forma condensed consolidated balance sheet as of December 31, 2014, and the pro-forma condensed consolidated statement of operations for the year ended December 31, 2014, have been prepared to comply with Article 11 of Regulation S-X, as promulgated by the Securities and Exchange Commission. The pro-forma condensed consolidated balance sheet as of December 31, 2014, is presented as if the acquisition of the Property was completed on December 31, 2014. The pro-forma condensed consolidated statement of operations for the year ended December 31, 2014, is presented as if the acquisition of the Property was completed on January 1, 2014. The pro-forma condensed consolidated balance sheet as of December 31, 2014, and the pro-forma condensed consolidated statement of operations for the year ended December 31, 2014, are not necessarily indicative of what the actual financial position and operating results would have been had the Property acquired in the current year been acquired on December 31, 2014, and January 1, 2014, respectively, nor do they purport to represent the Company’s future financial position or operating results.

The unaudited pro-forma condensed consolidated financial statements should be read in conjunction with the consolidated financial statements of Gladstone Land Corporation and the accompanying notes thereto in its Annual Report on Form 10-K for the year ended December 31, 2014, filed with the Securities and Exchange Commission on February 24, 2015, and the historical statement of revenues, filed in accordance with Rule 3-14 of Regulation S-X, of Espinosa Road, for the year ended December 31, 2014. In the Company’s opinion, all adjustments necessary to reflect the effect of the Property acquired have been made.
