Press Releases

OKLAHOMA CITY, OKLAHOMA, MARCH 1, 2011 – Chesapeake Midstream Partners, L.P. (NYSE:CHKM) today announced financial results for the 2010 fourth quarter. The results include the Partnership's acquisition of the Springridge gathering system from Chesapeake Energy Corporation ("Chesapeake") (NYSE:CHK), which closed on December 21, 2010. In addition, the Partnership reaffirmed its 2011 outlook and capital program.

Net income for the 2010 fourth quarter totaled $89.9 million, an increase of $39.2 million versus the 2009 fourth quarter. The Partnership's adjusted ebitda for the 2010 fourth quarter was $115.6 million and distributable cash flow ("DCF") was $96.7 million. Financial terms are defined on page 3 of this release. Fourth quarter results include operations of the Springridge assets from the closing of the acquisition on December 21, 2010 through the end of the year as well as associated transaction costs. DCF for the 2010 full year resulted in a 1.15 coverage ratio as compared to the minimum quarterly distribution.

Total throughput for the 2010 fourth quarter was 151.1 billion cubic feet (bcf) of natural gas or 1.642 bcf per day, an increase of 6% from the 2009 fourth quarter throughput of 1.550 bcf per day. The increase is the result of 427 new wells connected to the Partnership's gathering systems during 2010 (excluding wells added as a result of the Springridge acquisition) and new Springridge volumes. Revenue for the 2010 fourth quarter was $162.5 million, an increase of 51% from 2009 fourth quarter revenue of $107.4 million. Revenue includes $56.8 million and $7.7 million from the Partnership's minimum volume commitments ("MVCs") in 2010 and 2009, respectively. Revenue for the 2010 fourth quarter increased 6% excluding the impact of MVCs.

The Partnership invested approximately $59.8 million on capital expenditures during the 2010 fourth quarter, including maintenance capital expenditures of approximately $17.5 million. Maintenance capital expenditures consist primarily of well connect costs required to replace natural declines in gathering volumes.

Partnership Completes First Acquisition

On December 21, 2010, the Partnership closed on its first asset acquisition, acquiring from Chesapeake a 100% ownership in the Springridge gathering system which consists of 226 miles of gathering pipeline in Caddo and De Soto parishes, Louisiana. At the end of 2010, the system's throughput was over 440 mmcf per day. The acquisition allows the Partnership to broaden its operating footprint and provides access to the Haynesville Shale, which is one of the largest and lowest cost natural gas fields in the United States.

Partnership Declares Cash Distribution

On January 28, 2011, the Board of Directors of the Partnership's general partner declared a quarterly cash distribution of $0.3375 per unit for the 2010 fourth quarter. The distribution was paid on February 14, 2011 to unitholders of record at the close of business on February 10, 2011. Adjusted distributable cash flow for the 2010 fourth quarter was $48.9 million, which provided distribution coverage of 1.03 times the amount required for the Partnership to fund the distribution to both the general and limited partners.

Outlook for 2011 Unchanged

The Partnership is projecting ebitda for the twelve months ended December 31, 2011 to be $332 million with expansion capital expenditures of $256 million and maintenance capital expenditures of $74 million. The ebitda projection includes revenue related to MVCs of $21 million. The MVCs are contractually calculated on an annual basis and are not recognized until the fourth quarter of each year. Thus, revenue related to these commitments will not be recognized during the first three quarters of each year.

Management Comments

J. Mike Stice, Chesapeake Midstream Partners' Chief Executive Officer, commented, "I'm pleased to announce our operating and financial results continue to be in line with our projections. The implied 2010 full-year coverage ratio was 1.15, right on target for our business model. We were able to close the Springridge acquisition before the end of the year and more importantly, to fully integrate the system's operations so we are prepared to deliver immediate volume growth in 2011. Throughput on the Springridge system during the first two months following the acquisition has exceeded our original expectations, confirming the attractiveness of this premier growth asset."

Use of Non-GAAP Financial Measures

This press release and accompanying schedules include the non-GAAP financial measures of adjusted ebitda and distributable cash flow. The accompanying schedules provide reconciliations of these non-GAAP financial measures to their most directly comparable financial measure calculated and presented in accordance with GAAP. Non-GAAP financial measures should not be considered as an alternative to GAAP measures such as net income, net cash provided by operating activities or any other measure of liquidity or financial performance calculated and presented in accordance with GAAP. Investors should not consider adjusted ebitda or distributable cash flow in isolation or as a substitute for analysis of the Partnership's results as reported under GAAP. Because these non-GAAP financial measures may be defined differently by other companies in our industry, the Partnership's definition of adjusted ebitda and distributable cash flow may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

Adjusted Ebitda. The Partnership defines adjusted ebitda as net income (loss) before income tax expense, interest expense, depreciation and amortization expense and certain other items management believes affect the comparability of operating results. Adjusted ebitda is a non-GAAP financial measure that management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies, may use to assess:

• The Partnership's operating performance as compared to other publicly traded partnerships in the midstream energy industry, without regard to capital structure, historical cost basis or financing methods;
• The Partnership's ability to incur and service debt and fund capital expenditures;
• The ability of the Partnership's assets to generate sufficient cash flow to make distributions to unitholders; and
• The viability of acquisitions and other capital expenditure projects and the returns on investment of various investment opportunities.

Management believes it is appropriate to exclude certain items from ebitda because management believes these items affect the comparability of operating results. The Partnership believes that the presentation of adjusted ebitda in this press release provides information useful to investors in assessing its financial condition and results of operations. The GAAP measure most directly comparable to adjusted ebitda is net income.

Distributable Cash Flow. The Partnership defines distributable cash flow as adjusted ebitda attributable to the Partnership adjusted for:

• Addition of interest income;
• Subtraction of net cash paid for interest expense;
• Subtraction of maintenance capital expenditures; and
• Subtraction of income taxes.

Management compares the distributable cash flow the Partnership generates to the cash distributions it expects to pay its partners. Using this metric, management computes a distribution coverage ratio. Distributable cash flow is an important non-GAAP financial measure for our limited partners since it serves as an indicator of our success in providing a cash return on investment. Specifically, this financial measure indicates to investors whether or not the Partnership is generating cash flows at a level that can sustain or support an increase in its quarterly cash distributions. Distributable cash flow is also a quantitative standard used by the investment community with respect to publicly traded partnerships because the value of a partnership unit is in part measured by its yield, which is based on the amount of cash distributions a partnership can pay to a unitholder. The GAAP measure most directly comparable to distributable cash flow is net cash provided by operating activities.
