Recent Acquisitions

RSP recently acquired additional acreage prospective for horizontal development located in Martin, Glasscock, and Dawson counties for an aggregate purchase price of approximately $79 million in three separate transactions. The transactions were financed under RSP’s revolving credit facility.

East Cowden Acquisition

On February, 24th, RSP closed on the acquisition of a 17.5% non-operated working interest in producing properties. The properties are located between RSP Permian’s operated leasehold positions in Martin County, Texas. The properties include 6,451 gross (1,125 net) acres, and net production, on a two-stream basis, averaged approximately 500 barrels of oil equivalent (“Boe”) per day (76% oil) for the month of February from 147 vertical wells. The operator of these properties has indicated it has identified 196 horizontal drilling locations in six target intervals including the Middle Spraberry, Lower Spraberry, Wolfcamp A, Wolfcamp B, Wolfcamp D (Cline), and Clearfork.

Dude Acquisition

In Glasscock County, RSP acquired a 100% operated working interest in 961 acres of undeveloped leasehold.  RSP has identified 30 horizontal locations located on these properties located in the Middle Spraberry, Lower Spraberry, Wolfcamp A, Wolfcamp B, and Wolfcamp D (Cline) formations.

Verde “Bolt-on” Acquisition

RSP also added to its position in Dawson County, closing on an additional 3,766 gross (3,230 net) undeveloped acres in the Company’s Verde area, bringing the Company’s total acreage in Dawson to 13,230 gross (11,345 net) acres. The Company has identified approximately 61 additional net horizontal locations in the Middle Spraberry, Lower Spraberry, and Wolfcamp A/B formations.

“These opportunistic acquisitions expand our horizontal inventory in properties that are located primarily adjacent to our existing leasehold, further blocking up contiguous acreage in our area of operations,” said RSP Permian’s Chief Executive Officer Steve Gray. “These acquisitions were accomplished using our deep rooted relationships within the Permian Basin, which we believe is a core strength of the RSP organization and will lead to future attractive acquisition opportunities in our core areas. We look forward to executing on the horizontal development program on these properties, targeting multiple prospective zones. ”

Statement of Operations

8

(1)         RSP Permian, L.L.C. was formed as a holding company in October 2010, and did not conduct any material business operations until December 2010. RSP Permian, Inc. is a C-Corp. under the Code, and is subject to income taxes. The Company computed a pro forma income tax provision for 2012 and 2013 as if RSP Permian, L.L.C. and Rising Star were subject to income taxes since January 1, 2012. For 2013 and 2012 comparative purposes, we have included pro forma financial data to give effect to income taxes assuming the earnings of the RSP Permian, L.L.C. and Rising Star had been subject to federal income tax as a C-Corp. since inception. The unaudited pro forma data is presented for informational purposes only and does not purport to project our results of operations for any future period or our financial position as of any future date. The pro forma tax provision has been calculated at a rate based upon a federal corporate level tax rate and a state tax rate, net of federal benefit, incorporating permanent differences.

(2)         Adjusted EBITDAX is a non-GAAP financial measure. For a definition of Adjusted EBITDAX and a reconciliation of Adjusted EBITDAX to net income, see “Use of Non-GAAP Financial Measures” below.

Use of Non-GAAP Financial Measures

We define Adjusted EBITDAX as net income (loss) before interest expense, income taxes, depreciation, depletion and amortization, exploration expense, (gains) losses on derivative instruments excluding net cash receipts (payments) on settled derivative instruments and premiums paid on put options that settled during the period, impairment of oil and natural gas properties, non-cash equity based compensation, asset retirement obligation accretion expense, gains and losses from the sale of assets and other non-cash operating items.

Management believes Adjusted EBITDAX is useful because it allows it to more effectively evaluate our operating performance and compare the results of our operations from period to period without regard to our financing methods or capital structure. We exclude the items listed above from net income in arriving at Adjusted EBITDAX because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDAX should not be considered as an alternative to, or more meaningful than, net income as determined in accordance with GAAP or as an indicator of our operating performance or liquidity. Certain items excluded from Adjusted EBITDAX are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic costs of depreciable assets, none of which are components of Adjusted EBITDAX. Our computations of Adjusted EBITDAX may not be comparable to other similarly titled measures of other companies.

The following table presents a pro forma reconciliation of the non-GAAP financial measure of Adjusted EBITDAX to the GAAP financial measure of net income (loss).
