Exhibit 99.3

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

This pro forma information should be read in conjunction with the historical consolidated financial statements and notes thereto of CatchMark Timber Trust, Inc. (“CatchMark”) included in its annual report filed on Form 10-K for the year ended December 31, 2017 and its quarterly report on Form 10-Q for the three months ended March 31, 2018 and the historical combined carve-out financial statements of Crown Pine Timber 1, L.P. and affiliated entities (“Crown Pine”) which are contained in the current report filed on Form 8-K that contains these unaudited pro forma condensed consolidated financial statements.

On May 14, 2018, CatchMark Timber Operating Partnership, L.P, our wholly owned subsidiary, entered into a letter agreement (the “CTT Equity Commitment Letter”) providing for a $227.5 million equity investment in Creek Pine Holdings, LLC (“Holdings”), to be funded using a combination of cash-on-hand and borrowings under our credit facility (the “Investment”). Also on that date, Holdings entered into letter agreements with affiliates of BTG Pactual Timberland Investment Group, Highland Capital Management, Medley Capital LLC and other equity investors (collectively, the “Outside Investors”) providing for aggregate investments of $665 million before deducting original issuance discounts by the Outside Investors into Holdings in connection with the establishment of a joint venture, TexMark Timber Treasury (“Triple T Timberlands”).

The purpose of Triple T Timberlands is to complete the transactions contemplated by the Crown Pine Purchase Agreement (“Crown Pine Purchase Agreement”) by and among Holdings, Crown Pine, Crown Pine Parent, L.P., Crown Pine REIT, Inc. and GPT1 LLC. The Crown Pine Purchase Agreement provides for the acquisition by Holdings of all of the outstanding partnership interests in Crown Pine for approximately $1.39 billion in cash (the “Acquisition”), subject to certain adjustments. Crown Pine and its subsidiaries are the fee simple owners of 1,099,875 gross acres of fee simple lands located in Southeast Texas.

The purchase price will be financed through the proceeds of the equity contributions to Holdings described above and up to a $650 million, seven-year term loan to be made pursuant to the terms and conditions of a debt commitment letter, dated May 14, 2018 between Holdings and CoBank ACB. Borrowings under the term loan will bear interest at a floating rate equal to LIBOR or a base rate, plus a margin determined based upon a loan-to-value ratio and will be secured by all of the assets of Triple T Timberlands and Crown Pine.

In connection with the establishment of Triple T Timberlands, an indirect subsidiary of CatchMark is expected to enter into an asset management agreement, pursuant to which such CatchMark subsidiary will receive an initial asset management fee equal to approximately 1.1% of the purchase price for the Acquisition multiplied by the Outside Investor’s relative equity percentage. The fee is subject to step-down if certain return thresholds are not met with respect to the Outside Investors.

The following unaudited pro forma condensed consolidated financial statements give effect to the Investment and related financings as if they had been completed on March 31, 2018 with respect to the pro forma consolidated balance sheet and as of January 1, 2017 with respect to the pro forma consolidated statement of operations. Pro forma adjustments are included only to the extent they are factually supportable and, with respect to the unaudited pro forma consolidated statement of operations, expected to have a continuing impact on the results of operations of CatchMark.

The unaudited pro forma consolidated statement of operations for the year ended December 31, 2017 and the three months ended March 31, 2018 have been developed from CatchMark’s historical consolidated statement of operations for such year and three-month period and Crown Pine’s historical combined carve-out statement of operations for such year and three-month period. The unaudited pro forma consolidated balance sheet has been developed from CatchMark’s historical consolidated balance sheet as of March 31, 2018 and Crown Pine’s historical combined carve-out balance sheet as of March 31, 2018.

Adjustments to the Unaudited Pro Forma Condensed Consolidated Financial Statements

The unaudited pro forma consolidated balance sheet as of March 31, 2018 and the unaudited pro forma consolidated statements of operations for the three months ended March 31, 2018 and the year ended December 31, 2017 reflect the following adjustments:

Represents cash on-hand used by CatchMark to partially fund the Investment, which in turn will be used by Triple T Timberlands to pay a portion of the $1.38 billion purchase price for the Acquisition.

Represents the elimination of historical balances of Crown Pine as CatchMark accounts for the Investment using the equity method of accounting. See note D for additional information on the equity method and CatchMark’s Investment in Unconsolidated Joint Ventures.

Represents the elimination of the historical balance of Crown Pine ($4.2 million) plus the reclassification of deferred joint venture pursuit costs incurred by CatchMark to its investment in unconsolidated joint ventures ($2.3 million).

For joint ventures that it does not control but exercises significant influence, CatchMark uses the equity method of accounting. Under the equity method, the investment in a joint venture is recorded at cost and adjusted for equity in earnings and cash contributions and distributions. Income or loss and cash distributions from an unconsolidated joint venture are allocated according to the provisions of the respective joint venture agreement, which may be different from its stated ownership percentage. CatchMark’s equity in earnings (losses) of the unconsolidated Triple T Timberlands joint venture is determined using the hypothetical liquidation-at-book value (“HLBV”) method.

The pro forma adjustment represents the book basis of CatchMark’s investment in the unconsolidated Triple T Timberlands joint venture assuming an initial $227.5 million contribution and its pro forma equity in earnings (losses) for the three months ended March 31, 2018 determined using HLBV. The following table summarizes the pro forma adjustments made to Investment in Unconsolidated Joint Ventures related to the Investment as of March 31, 2018 (in thousands):

See note F for additional information on the determination of CatchMark’s equity in earnings (losses) of the unconsolidated Triple T Timberlands joint venture.

Represents borrowings from CatchMark’s credit facilities used to partially fund the Investment, which in turn will be contributed to and used by Triple T Timberlands to pay a portion of the $1.38 billion purchase price for the Acquisition.

Represents CatchMark’s equity in earnings (losses) of the unconsolidated Triple T Timberlands joint venture determined using HLBV as if the Investment and Acquisition had been completed on March 31, 2018, the date of the unaudited pro forma consolidated balance sheet. CatchMark’s pro forma equity in earnings (losses) of Triple T Timberlands determined using HLBV results primarily from distribution preferences and transaction costs incurred by Triple T Timberlands in the period of Acquisition and are not consistent with the historical results of operations of Crown Pine. The following table summarizes the pro forma adjustment made to Accumulated Deficit and Distributions related to the Investment as of March 31, 2018 (in thousands):

Represents management fee revenue in the amount of approximately 1.1% of the purchase price of the Acquisition multiplied by the Outside Investors’ relative equity percentage.

Represents interest expense on proceeds drawn from credit facilities of CatchMark to partially fund the Investment, which in turn will be contributed to and used by Triple T Timberlands to pay a portion of the $1.38 billion purchase price for the Acquisition. CatchMark’s credit facilities bear interest at London Interbank Offered Rate, or LIBOR, plus a spread of 1.50% to 2.20%, depending on loan-to-value ratio, as defined per the credit agreements. For purposes of pro forma adjustments, such borrowings bore interest at a weighted-average variable rate of approximately 3.63% and 3.09% for the three months ended March 31, 2018 and the year ended December 31, 2017,

respectively. A 1.0% change in interest rates would result in a change in interest expense of approximately $0.5 million and $2.2 million for the three months ended March 31, 2018 and the year ended December 31, 2017, respectively.

Represents CatchMark’s income (loss) from unconsolidated joint ventures based on its equity in earnings (losses) of the unconsolidated Triple T Timberlands joint venture determined using HLBV as if the Investment and Acquisition had been completed on January 1, 2017. CatchMark’s pro forma equity in earnings (losses) of Triple T Timberlands determined using HLBV results primarily from distribution preferences and transaction costs incurred by Triple T Timberlands in the period of Acquisition and are not consistent with the historical results of operations of Crown Pine. The following table summarizes the pro forma adjustment made to Income from Unconsolidated Joint Ventures for the three months ended March 31, 2018 and the year ended December 31, 2017 (in thousands):

Represents interest expense savings, net of the associated $1.4 million write-off of deferred financing costs in the year ended December 31, 2017, related to the repayment of $69.0 million of outstanding debt in March 2018 with net proceeds from CatchMark’s public equity offering conducted in March 2018. This debt repayment is reflected in CatchMark’s historical notes payable and lines of credit balance as of March 31, 2018.

Pro forma weighted-average common shares outstanding – basic and diluted represent the number of shares outstanding at the end of the period as if they were issued and outstanding during the entire period after giving effect to CatchMark’s public equity offering conducted in March 2018.
