Item 7.01. Regulation FD Disclosure

Southern Union Company (the "Company") issued a press release on May 11, 2009, reporting its 2009 first quarter results and confirming an investor call scheduled for 9 a.m. (ET) today to discuss those results. The Company is furnishing the press release, attached as Exhibit 99.1, pursuant to Item 2.02 and Item 7.01.

The press release contains earnings guidance affirming expected financial performance for the year ending December 31, 2009. The earnings guidance presented in the press release under Item 7.01 shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, except as expressly set forth by specific reference in such a filing.

In the earnings release, the Company uses earnings before interest and taxes (EBIT) and adjusted EBIT, non-GAAP financial measures, as performance measures to evaluate Company and segment performance. As defined in Regulation G, "Conditions for Use of Non-GAAP Financial Measures," a non-GAAP financial measure is a numerical measure of a company's historical or future performance, financial position or cash flow that excludes (includes) amounts, or is subject to adjustments that have the effect of excluding (including) amounts, that are included (excluded) in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles (GAAP).

The Company defines EBIT as net earnings (loss) available for common shareholders, adjusted for: (i) items that do not impact earnings (loss) from continuing operations, such as extraordinary items, discontinued operations and the impact of accounting changes; (ii) income taxes; (iii) interest; (iv) dividends on preferred stock; and (v) loss on extinguishment of preferred stock. EBIT may not be comparable to measures used by other companies. Additionally, EBIT should be considered in conjunction with net earnings and other performance measures such as operating income or operating cash flow. In the earnings release, the Company reported adjusted EBIT for its 2009 first quarter results by (i) excluding mark-to-market unrealized losses on open economic hedges of 2009 processing spreads; (ii) including mark-to-market gains recognized in a prior accounting period, but excluded from the prior period's adjusted earnings; and (iii) excluding a charge to increase repair and abandonment costs related to certain of the Company's offshore facilities resulting from Hurrican Ike damage.
