Tallgrass Energy Partners, LP (NYSE: TEP) ("TEP") and Tallgrass Energy GP, LP (NYSE: TEGP) ("TEGP") today reported financial and operating results for the second quarter of 2015. TEP and TEGP are collectively referred to as Tallgrass Energy.

"We are reporting another record quarter at TEP and announcing TEGP's results for its first quarter as a public company," said David G. Dehaemers, Jr., President and CEO of Tallgrass Energy. "Our second quarter distribution increased 11.5 percent compared to the first quarter of 2015, thanks to solid performance at each of our business segments and our ownership of a 66.7 percent membership interest in Pony Express. As a result, TEP has already met our 20 percent distribution growth guidance for the full year 2015 with half of the year still remaining. Since our beginning in 2012, the Tallgrass Energy team has successfully executed our plan and delivered exceptional results, even in the challenging environment recently facing the energy commodity markets."

The financial results for all periods presented in the table below include the applicable results of operations of our 33.3 percent membership interest in Tallgrass Pony Express Pipeline, LLC (“Pony Express”), which was acquired by TEP effective September 1, 2014, except for the period under the column "As Reported in 2014." The acquisition of an additional 33.3 percent membership interest in Pony Express effective March 1, 2015, is presented prospectively from the date of acquisition, and as a result, financial information for periods prior to March 1, 2015, have not been recast to reflect the additional 33.3 percent membership interest. The financial results for all periods presented in the table below, including the period "As Reported in 2014," include the results of Trailblazer Pipeline Company LLC, which was acquired by TEP effective April 1, 2014.

Summary Financial Information

The "As Reported in 2014" columns for the three and six months ended June 30, 2014, include the impact of the distributions paid on the 8.05 million units issued on July 25, 2014. Excluding the impact of the distributions paid on the 8.05 million units, coverage would have been 0.94x and 1.18x for the three and six months ended June 30, 2014.

Segment Overview

The second quarter 2015 results by segment are summarized below:

The segment reporting in the table above does not include corporate general and administrative costs or intersegment eliminations. The Crude Oil Transportation & Logistics segment includes figures for 2014 although Pony Express Pipeline was not owned by TEP and did not generate revenue during the three or six month periods ending June 30, 2014.

Adjusted EBITDA in the Natural Gas Transportation & Logistics segment for the second quarter of 2015 was $16.6 million, representing an increase of $1.5 million as compared to the second quarter of 2014 primarily due to lower operating costs and expenses. Average firm contracted transportation capacity of 1,520 MMcf/d for the second quarter of 2015 was slightly higher than the 1,494 MMcf/d for the second quarter of 2014. When comparing the Natural Gas Transportation & Logistics segment's Adjusted EBITDA for the second quarter of 2015 to its $19.2 million of Adjusted EBITDA for the first quarter of 2015, the decrease of $2.6 million is primarily attributable to lower transportation revenues and higher operating costs.

The Crude Oil Transportation & Logistics segment Adjusted EBITDA was $46.3 million for the second quarter of 2015, representing the operating results of the Pony Express mainline and the lateral in Northeast Colorado, which were placed into commercial service in October 2014 and April 2015, respectively. There were no operating results for the second quarter of 2014 as Pony Express had not yet commenced commercial operations. The Adjusted EBITDA for the second quarter of 2015 represents an increase of $20.8 million over the first quarter of 2015 which was primarily the result of the acquisition of an additional 33.3 percent membership interest in Pony Express on March 1, 2015, the full operation of one of the upstream pipelines that delivers volumes to Pony Express and a decrease in property tax expense estimates during the second quarter of 2015. TEP received distributable cash flow from Pony Express of $40.3 million for its 66.7 percent membership interest for the second quarter of 2015 which is greater than the minimum quarterly preference payment of $36.7 million.

The Processing & Logistics segment generated Adjusted EBITDA of $7.1 million for the second quarter of 2015, representing an increase of $1.6 million as compared to the second quarter of 2014. The increase was primarily due to increased revenues at the water services business during the second quarter of 2015. Approximate average inlet volumes at the processing facilities were 130 MMcf/day for the second quarter of 2015 as compared to 136 MMcf/day for the second quarter of 2014. When comparing the Processing & Logistics segment's $7.1 million of Adjusted EBITDA for the second quarter of 2015 to its Adjusted EBITDA of $8.7 million for the first quarter of 2015, the decrease is primarily attributable to lower average inlet volumes at the processing facilities.

TEP's Non-GAAP Measures

Adjusted EBITDA and distributable cash flow are non-GAAP supplemental financial measures that TEP management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies, may use to assess:

• our operating performance as compared to other publicly traded partnerships in the midstream energy industry, without regard to historical cost basis or, in the case of Adjusted EBITDA, financing methods;

• the ability of our assets to generate sufficient cash flow to make distributions to our unitholders;

• our ability to incur and service debt and fund capital expenditures; and

• the viability of acquisitions and other capital expenditure projects and the returns on investment of various expansion and growth opportunities.

We believe that the presentation of Adjusted EBITDA and distributable cash flow provides useful information to investors in assessing our financial condition and results of operations. Adjusted EBITDA and distributable cash flow should not be considered alternatives to net income, operating income, cash from operations or any other measure of financial performance or liquidity presented in accordance with GAAP, nor should Adjusted EBITDA and distributable cash flow be considered alternatives to available cash, operating surplus, distributions of available cash from operating surplus or other definitions in our partnership agreement. Adjusted EBITDA and distributable cash flow have important limitations as analytical tools because they exclude some but not all items that affect net income and net cash provided by operating activities. Additionally, because Adjusted EBITDA and distributable cash flow may be defined differently by other companies in our industry, our definition of Adjusted EBITDA and distributable cash flow may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

We define Adjusted EBITDA as net income excluding the impact of interest, income taxes, depreciation and amortization, non-cash income or loss related to derivative instruments, non-cash long-term compensation expense, impairment losses, gains or losses on asset or business disposals or acquisitions, gains or losses on the repurchase, redemption or early retirement of debt, and earnings from unconsolidated investments, but including the impact of distributions from unconsolidated investments. We define distributable cash flow as Adjusted EBITDA, plus preferred distributions received from Pony Express in excess of its distributable cash flow attributable to our net interest and adjusted for deficiency payments received from or utilized by Pony Express shippers, less cash interest expense, maintenance capital expenditures, and distributions to noncontrolling interests in excess of earnings allocated to noncontrolling interests. For a reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measures, please see "Summary Financial Information" above.
