Titan Energy 8-K/A Financial Statements and Exhibits

Exhibit 99.5

UNAUDITED PRO FORMA FINANCIAL INFORMATION

The following unaudited pro forma consolidated combined financial data reflects Atlas Resource Partners, L.P.’s (the “Partnership”) historical results as adjusted on a pro forma basis to give effect to its acquisitions of (i) certain assets from Carrizo Oil & Gas, Inc. (NASDAQ: CRZO; “Carrizo”) on April 30, 2012 and the related issuance of 6.0 million common limited partner units in a private placement to partially fund the purchase price, and (ii) certain proved reserves and associated assets from Titan Operating, L.L.C. (“Titan”) on July 25, 2012 for 3.8 million Partnership common units and 3.8 million convertible Class B preferred units, as well as $15.4 million in cash for closing adjustments. The estimated adjustments to effect the acquisitions are described in the notes to the unaudited pro forma financial data.

The unaudited pro forma consolidated balance sheet information as of June 30, 2012 reflects the acquisition of Titan for 3.8 million Partnership common units and 3.8 million convertible Class B preferred units, as well as $15.4 million in cash for closing adjustments, which was funded through borrowings under the Partnership’s revolving credit facility. In addition, Carrizo was included in the historical balance sheet as the acquisition occurred on April 30, 2012.

The unaudited pro forma consolidated combined statements of operations information for the six months ended June 30, 2012 and the twelve months ended December 31, 2011 reflect the following transactions as if they occurred as of the beginning of the respective period:

• the acquisition of Titan for 3.8 million Partnership common units and 3.8 million convertible Class B preferred units, as well as $15.4 million in cash for closing adjustments, which was funded through borrowings under the Partnership’s revolving credit facility; and

• the acquisition from Carrizo for gross cash consideration of $190.0 million, net of $3.0 million of purchase price reductions for working capital and other amounts, which was funded through (i) the private placement of 6,027,945 common limited partner units to investors at a negotiated purchase price of $20.00 per unit and (ii) borrowings of $67.5 million under the Partnership’s revolving credit facility.

The unaudited pro forma consolidated balance sheet and the pro forma consolidated combined statements of operations were derived by adjusting the Partnership’s historical consolidated combined financial statements. However, management of the Partnership believes that the adjustments provide a reasonable basis for presenting the significant effects of the transactions described above. The unaudited pro forma financial data presented is for informational purposes only and is based upon available information and assumptions that management of the Partnership believes are reasonable under the circumstances. This unaudited pro forma financial information is not necessarily indicative of what the financial position or results of operations of the Partnership would have been had the transactions been consummated on the dates assumed, nor are they necessarily indicative of any future operating results or financial position. The Partnership may have performed differently had the transactions actually occurred on the dates assumed.

The Partnership was formed in October 2011 by Atlas Energy, L.P. (“ATLS”), a publicly traded master-limited partnership (NYSE: ATLS), to own and operate substantially all of ATLS’s exploration and production assets, which were transferred to the Partnership on March 5, 2012. In February 2012, the board of directors of ATLS’s general partner approved the distribution of 5.24 million of the Partnership’s common limited partner units which were distributed on March 13, 2012 to ATLS’ unitholders using a ratio of 0.1021 of the Partnership’s common limited partner units for each of ATLS’ common units owned on the record date of February 28, 2012.

The Partnership’s historical consolidated balance sheet at June 30, 2012 and the portion of its historical consolidated combined statement of operations for the six months ended June 30, 2012 subsequent to the transfer of assets on March 5, 2012 include its and its wholly-owned subsidiaries accounts. The portion of the Partnership’s historical consolidated combined statements of operations for the six months ended June 30, 2012 prior to the transfer of assets on March 5, 2012 and the combined statement of operations for the year ended December 31, 2011 were derived from the separate records maintained by ATLS and may not necessarily be indicative of the conditions that would have existed if the Partnership had been operated as an unaffiliated entity. Accounting principles general accepted in the United States of America require management to make estimates and assumptions that affect the amounts reported in consolidated combined balance sheets and related consolidated combined statements of operations. Such estimates included allocations made from the historical

43

accounting records of ATLS, based on management’s best estimates, in order to derive the Partnership’s financial statements for the periods presented prior to the transfer of assets. Actual balances and results could be different from those estimates.

On February 17, 2011, ATLS acquired its exploration and production assets (the “Transferred Business”) from Atlas Energy, Inc. (“AEI”), the former owner of ATLS’s general partner. Upon its acquisition, ATLS’s management determined that the acquisition constituted a transaction between entities under common control. In comparison to the acquisition method of accounting, whereby the purchase price for the asset acquisition would have been allocated to identifiable assets and liabilities of the Transferred Business with any excess treated as goodwill, transfers between entities under common control require that assets and liabilities be recognized by the acquirer at historical carrying value at the date of transfer, with any difference between the purchase price and the net book value of the assets recognized as an adjustment to partners’ capital. Also, in comparison to the acquisition method of accounting, whereby the results of operations and the financial position of the Transferred Business would have been included in ATLS’s consolidated combined financial statements from the date of acquisition, transfers between entities under common control require the acquirer to reflect the effect of the assets acquired and liabilities assumed and the related results of operations at the beginning of the period during which it was acquired and retrospectively adjust its prior year financial statements to furnish comparative information. As such, ATLS reflected the impact of the acquisition of the Transferred Business on its consolidated combined financial statements, which are the basis of the Partnership’s consolidated combined financial statements for the period prior to the transfer of assets on March 5, 2012, in the following manner:

• Recognized the assets acquired and liabilities assumed from the Transferred Business at their historical carrying value at the date of transfer, with any difference between the purchase price and the net book value of the assets recognized as an adjustment to partners’ capital; and

• Retrospectively adjusted its consolidated combined financial statements for any date prior to February 17, 2011, the date of the Transferred Business acquisition, to reflect its results on a consolidated combined basis with the results of the Transferred Business as of or at the beginning of the respective period. The Transferred Business’ historical financial statements prior to the date of acquisition reflect an allocation of general and administrative expenses determined by AEI to the underlying business segments, including the Transferred Business. ATLS has reviewed AEI’s general and administrative expense allocation methodology, which is based on the relative total assets of AEI and the Transferred Business, for the Transferred Business’ historical financial statements prior to the date of acquisition and believes the methodology is reasonable and reflects the approximate general and administrative costs of its underlying business segments.

With regard to the calculation of pro forma net income (loss) per common limited partner unit, the general partner’s Class A unit interest in net income (loss) is calculated on a quarterly basis based upon its 2% Class A ownership interest and incentive distributions, with a priority allocation of net income in an amount equal to the general partner’s actual incentive distributions for the respective period, in accordance with the partnership agreement, and the remaining net income or loss is allocated with respect to the general partner’s and limited partners’ ownership interests.
