Inergy Announcement FAQ

 

1. What was announced?

 

  We have completed the first steps in our previously announced agreement to combine Crestwood and Inergy to create a fully integrated midstream partnership with a total enterprise value of approximately $7 billion.

 

  Crestwood Holdings has acquired the general partner, and thus control, of Inergy, L.P.

 

  Additionally, Crestwood Gas Services Holdings LLC, a wholly owned subsidiary of Crestwood Holdings, contributed 100% of its interest in Crestwood Gas Services GP LLC, the general partner of Crestwood Midstream that also owns 100% of the incentive distribution rights of Crestwood Midstream Partners LP for common units and subordinated units in Inergy, L.P.

 

  As outlined in prior announcements, Robert G. Phillips, current Chairman, President and Chief Executive Officer of Crestwood Midstream, has been named Chairman, President and Chief Executive Officer of Inergy, L.P. and Inergy Midstream, effective immediately.

 

  Prior Inergy Chairman and Chief Executive Officer, John J. Sherman, and President, R. Brooks Sherman, Jr., have stepped down from day-to-day management roles.

 

  John Sherman will continue to serve on the Boards of Directors of Inergy, L.P. and Inergy Midstream.

 

  Until the completion of the merger, both Crestwood Midstream and Inergy Midstream will continue to operate as separate, independent companies under a common corporate owner.

 

2. What does this mean? Is the merger of Inergy and Crestwood completed?

 

  As noted when this transaction was announced in early May, this process will require several steps before culminating with the final transaction, the merger of Crestwood Midstream with Inergy Midstream.

 

  We expect the final step of the merger process to be completed in the third quarter of 2013.

 

  Until then, the Crestwood and Inergy Midstream MLPs will continue operating as separate, independent companies under a common corporate owner.

 

3. Has the Board of Directors of Inergy changed? How?

 

  Yes. As was planned and outlined in prior announcements, Bob Phillips, current Chairman, President and CEO of Crestwood Midstream, has been named the Chairman, President and Chief Executive Officer of Inergy, LP and Inergy Midstream, effective immediately.

 

  Prior Inergy Chairman and Chief Executive Officer, John Sherman and President, Brooks Sherman, have stepped down from day-to-day management roles, though John Sherman will continue to serve on the Boards of Directors of Inergy, L.P. and Inergy Midstream.

 

  In addition to Mr. Phillips, Michael G. France, Managing Director at First Reserve and Managing Member of Crestwood Holdings, has been named to the Boards of Directors of Inergy, L.P. and Inergy Midstream, and Phillip L. Elbert has stepped down from the Board of Directors of Inergy, L.P.


  Prior to completion of the merger, Crestwood Holdings and Inergy, L.P. will designate three additional directors to each of the respective Boards of Directors of Inergy, L.P. and Inergy Midstream.

 

4. Has the management team of Inergy changed? How?

  Prior Inergy Chairman and Chief Executive Officer, John Sherman and President, Brooks Sherman, have stepped down from day-to-day management roles, and John Sherman will continue to serve on the Boards of Directors of Inergy, L.P. and Inergy Midstream.

 

  The executive management team of the combined company, which is expected to include senior executives from both companies, will be announced prior to completion of the merger.

 

5. I am an Inergy unitholder. How does this announcement impact me?

 

  Until the final transaction closes, which is expected to occur in the third quarter of 2013, unitholders of Crestwood Midstream Partners LP, Inergy, L.P. and Inergy Midstream, L.P. will see no change—the companies will operate and trade as separate, independent companies.

 

  Inergy, L.P. and Inergy Midstream, L.P. will continue to trade on the NYSE under the tickers NRGY and NRGM, respectively.

 

6. Will this have an impact on how Inergy does business? Will customers or vendors see any changes?

 

  This announcement should have no impact on Inergy’s day-to-day operations. Day-to-day contacts at the Company will remain the same for customers and vendors.

 

  Until the final merger is completed, the Crestwood and Inergy Midstream MLPs will continue to operate as separate, independent companies.
