SECTION 7.  REGULATION FD.

Item 7.01 Regulation FD Disclosure.

On May 25, 2006, Harold M. Korell, President and Chief Executive Officer of Southwestern Energy Company (the "Company") will be making a presentation at the Company's Annual Meeting of Shareholders that will include year-to-date operating information relating to the Fayetteville Shale play and net cash provided by operating activities before changes in operating assets and liabilities ("Discretionary Cash Flow") and earnings before income taxes, depreciation, depletion and amortization ("EBITDA").  Discretionary Cash Flow and EBITDA are non-GAAP measures that are reconciled below. A copy of the presentation is furnished herewith as Exhibit 99.1.

Net cash provided by operating activities before changes in operating assets and liabilities is presented because of its acceptance as an indicator of an oil and gas exploration and production company’s ability to internally fund exploration and development activities and to service or incur additional debt. The company has also included this information because changes in operating assets and liabilities relate to the timing of cash receipts and disbursements which the company may not control and may not relate to the period in which the operating activities occurred. Net cash provided by operating activities before changes in operating assets and liabilities should not be considered in isolation or as a substitute for net cash provided by operating activities prepared in accordance with generally accepted accounting principles.  The table below reconciles actual net cash provided by operating activities before changes in operating assets and liabilities with net cash provided by operating activities as derived from the company's financial information.

	3 Months Ended March 31,		12 Months Ended December 31,
	2006	2005	2005	2004
	(in thousands)
Net Cash provided by operating activities before changes in operating assets and liabilities	$125,369	$73,616	$321,758	$237,706
Add back (deduct):
Change in operating assets and liabilities	18,000	29,483	(17,276)	191
Net cash provided by operating activities	$143,369	$103,099	$304,482	$237,897

EBITDA is defined as net income plus interest, income tax expense, depreciation, depletion and amortization. Southwestern has included information concerning EBITDA because it is used by certain investors as a measure of the ability of a company to service or incur indebtedness and because it is a financial measure commonly used in the energy industry.  EBITDA should not be considered in isolation or as a substitute for net income, net cash provided by operating activities or other income or cash flow data prepared in accordance with generally accepted accounting principles or as a measure of the company's profitability or liquidity. EBITDA as defined above may not be comparable to similarly titled measures of other companies. Net income is a financial measure calculated and presented in accordance with generally accepted accounting principles. The table below reconciles historical EBITDA with historical net income.

	12 Months Ended December 31,

Depreciation, depletion and amortization	96,641	74,919	56,833		54,095	53,003	47,505		41,707

(1)    2000 amounts exclude unusual items of $109.3 million for the Hales judgment and $2.0 million for other litigation.

(2)    Provision for income taxes for 2003 includes the tax benefit associated with the cumulative effect of adoption of accounting principle.
