Southern Union Company (the “Company”) today issued a press release reporting its 2010 second quarter results and confirming an investor call scheduled for 9 a.m. (ET) 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, 2010. 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.

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 provides a full Regulation G reconciliation of the non-GAAP financial measures used to evaluate Company and segment performance in the press  release.
