Message from Rich Kinder

The dog days of summer will be coming to a close, another football season is upon us and Kinder Morgan is on its way to becoming a simpler, single entity which should help us grow more and faster in the future.

The reaction from Wall Street to our announcement to combine the Kinder Morgan companies has been overwhelmingly positive as evidenced by the uplift in our stock prices and analyst reports projecting a future price target at KMI of $45 to $50.  This is obviously good news for all of us as shareholders.  We also believe this transaction will help us grow more and faster in the future since we will have a lower cost of capital.  The rating agencies also like the pending transaction.  Moody’s issued an announcement in late August saying that an investment grade rating at KMI is likely, stating that KMI will have “a strong business profile supported by high-quality cash flow.”

There have been some questions (and speculation) about the tax implications, mostly in regard to KMP unitholders.  While each individual’s tax situation will obviously differ, we believe that, on average, KMP and EPB unit holders will be substantially better off on both a pre-tax and an after-tax basis versus continuing to hold KMP or EPB at the status quo when all aspects are taken into consideration.  As a newspaper columnist accurately pointed out, no one can escape death and taxes.  For those having to pay tax as a result of this transaction, it means that they made a profit.

We believe that it’s imperative to look at the entire transaction, not just the tax element, when evaluating the transaction.  With the premiums that all unitholders and shareholders will receive above the closing price of the equities the day before the transaction was announced, and the future growth projected for KMI’s dividend, we believe the transaction is beneficial to all.

We anticipate the approximately $70 billion transaction will be completed by year end following shareholder and unitholder votes at KMI, KMP, KMR and EPB, and standard regulatory approvals.  In late August, KMI was granted early termination of the waiting period under the Hart-Scott-Rodino (HSR) Antitrust Improvements Act for our proposed acquisition of KMP.  HSR approval is not needed for KMI’s purchase of KMR and EPB.

As a company, our goals remain unchanged.  We want to strive for both financial and operational excellence and to continue to grow the company and return value to our shareholders and unitholders.  I continue to believe that much of the success of a company is built on 5 percent inspiration and 95 percent perspiration and not caring who gets the credit when things go well.  We must remain focused on the details, operate our assets safely and efficiently and meet our customers’ needs.  Doing so will enable us to continue to be one of the premier midstream companies in the energy industry.  I truly believe the best is yet to come!
