Tallgrass Energy Reports Strong First Quarter 2018 Results

•$340 million of strategic acquisitions and organic growth projects announced during the quarter

•Healthy distribution coverage of 1.30x at TEP

•Conservative financial leverage of approximately 3.1x at TEP

LEAWOOD, Kan.--(BUSINESS WIRE)--May 3, 2018--Tallgrass Energy Partners, LP (NYSE: TEP) ("TEP") and Tallgrass Energy GP, LP (NYSE: TEGP) ("TEGP") today reported financial and operating results for the first quarter of 2018.

“Tallgrass Energy once again delivered the strong quarterly financial results that our unitholders and shareholders have come to expect,” said President and CEO David Dehaemers Jr. “These results were driven by consistent performance in our Natural Gas and Crude Oil transportation segments and continued growth in our Gathering, Processing and Terminalling segment, all of which led to our 19th and 11th consecutive distribution increases at TEP and TEGP, respectively.

"Our team remains focused on growing Tallgrass through strategic acquisitions and organically developed growth projects that will continue to expand our assets and footprint," added Dehaemers. "In addition, our team is also focused on completing TEGP’s pending acquisition of the publicly held TEP units that will result in a single unified public company, Tallgrass Energy, LP or TGE. We believe this streamlined entity, with shareholders receiving dividends and 1099s, will attract wider and more cost-effective capital investment to enhance shareholder returns on our commercial growth plans."

First Quarter Distributions

Tallgrass Energy Partners, LP

As previously announced, the board of directors of TEP's general partner declared a quarterly cash distribution of $0.975 per common unit for the first quarter of 2018. This quarterly distribution represents $3.90 on an annualized basis, a sequential increase of 1.0 percent from the fourth quarter 2017 distribution and an increase of 16.8 percent from the first quarter 2017 distribution. The quarterly distribution will be paid on May 15, 2018, to unitholders of record as of the close of business on April 30, 2018.

Tallgrass Energy GP, LP

Also, as previously announced, the board of directors of TEGP's general partner declared a quarterly cash dividend of $0.4875 per Class A share for the first quarter of 2018. This quarterly dividend represents $1.95 per Class A share on an annualized basis, a sequential increase of 32.7 percent from the fourth quarter 2017 dividend and an increase of 69.6 percent from the first quarter 2017 dividend. The quarterly dividend will be paid on May 15, 2018, to Class A shareholders of record as of the close of business on April 30, 2018.

Merger Transaction

In connection with the merger agreement announced on March 26, 2018, pursuant to which TEGP will acquire the TEP common units held by the public in a share-for-unit merger transaction that is taxable for U.S. federal income purposes at a ratio of 2.0 TEGP Class A shares for each outstanding TEP common unit, TEGP filed a registration statement on Form S-4 with the Securities and Exchange Commission (“SEC”) that includes a preliminary proxy statement for TEP unitholders. The registration statement has not yet been declared effective, although we anticipate that such registration statement will be declared effective and TEP will mail the definitive proxy statement to its unitholders in the coming weeks.

TEP has scheduled a special meeting of its unitholders to vote on the merger agreement and the transactions related thereto on June 26, 2018, at 10 a.m., Central Time, at the Hilton Garden Inn, 5800 College Boulevard, Overland Park, Kan. 66211. All holders of TEP common units as of the close of business on May 18, 2018, will be entitled to vote at such special meeting.

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 and financial statements of our subsidiaries and unconsolidated investments, 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, net cash provided by operating activities 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 generally 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 also use Distributable Cash Flow, which we generally define as Adjusted EBITDA, plus deficiency payments received from or utilized by our customers, less cash interest costs, maintenance capital expenditures, distributions to noncontrolling interests in excess of earnings allocated to noncontrolling interests, and certain cash reserves permitted by our partnership agreement. For a reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measures, please see "Summary Financial Information" above.

Cautionary Note Concerning Forward-Looking Statements

Disclosures in this press release contain “forward-looking statements.” All statements, other than statements of historical facts, included in this press release that address activities, events or developments that management expects, believes or anticipates will or may occur in the future are forward-looking statements. Without limiting the generality of the foregoing, forward-

looking statements contained in this press release specifically include whether the registration statement on Form S-4 TEGP filed with the SEC will be declared effective and the pending acquisition of TEP by TEGP will close and, if the transaction closes, whether it will attract wider and more cost-effective capital investments or enhance shareholder returns on our commercial growth plans. Forward looking statements may also include the expectations of plans, strategies, objectives and growth and anticipated financial and operational performance of TEP, TEGP and their subsidiaries, including: the ability to pursue expansions and other opportunities for incremental volumes; natural gas and crude oil production growth in TEP's operating areas; expected future benefits of acquisitions or expansion projects; timing of anticipated spending on planned expenses and maintenance capital projects; and distribution rate and growth, including variability of quarterly distribution coverage. These statements are based on certain assumptions made by TEP and TEGP based on management’s experience and perception of historical trends, current conditions, anticipated future developments and other factors believed to be appropriate. Such statements are subject to a number of assumptions, risks and uncertainties, many of which are beyond the control of TEP and TEGP, which may cause actual results to differ materially from those implied or expressed by the forward-looking statements. These include risks relating to TEP and TEGP’s financial performance and results, availability of sufficient cash flow to pay distributions and execute their business plans, the demand for natural gas storage, processing and transportation services and for crude oil transportation services, operating hazards, the effects of government regulation, tax position and other risks incidental to transporting, storing and processing natural gas or transporting crude oil and other important factors that could cause actual results to differ materially from those projected, including those set forth in reports filed by TEP and TEGP with the Securities and Exchange Commission. Any forward-looking statement applies only as of the date on which such statement is made and TEP and TEGP do not intend to correct or update any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law.

Tax Considerations

This release is intended to be a qualified notice to nominees and brokers under Treasury Regulation Sections 1.1446-4(b)(4) and (d). All of TEP’s distributions to foreign investors are attributable to income that is effectively connected with a United States trade or business. Accordingly, TEP’s distributions to foreign investors are subject to federal income tax withholding at the highest effective tax rate.
