Exhibit 99.1

ENERGY TRANSFER PARTNERS, L.P.

UNAUDITED PRO FORMA FINANCIAL INFORMATION

The following unaudited pro forma consolidated financial information of Energy Transfer Partners, L.P. (“ETP”) reflects the pro forma impacts of (i) ETP’s proposed transaction to contribute its propane operations to AmeriGas Partners, L.P. (“AmeriGas”) in exchange for approximately $2.9 billion in cash and common units representing limited partner interests in AmeriGas (the “Propane Transaction”) and (ii) ETP’s proposed Citrus Transaction (as defined below). These transactions are described more fully below.

The unaudited pro forma condensed consolidated balance sheet gives effect to the Propane Transaction and the Citrus Transaction as if both had occurred on September 30, 2011; the unaudited pro forma condensed consolidated statements of operations assume that both transactions were consummated on January 1, 2010. The unaudited pro forma condensed consolidated financial statements should be read in conjunction with (i) ETP’s Annual Report on Form 10-K for the year ended December 31, 2010, as filed with the Securities and Exchange Commission (the “SEC”) on February 28, 2011, and (ii) ETP’s quarterly report on Form 10-Q for the nine months ended September 30, 2011, as filed with the SEC on November 7, 2011.

The unaudited pro forma condensed consolidated financial statements are for illustrative purposes only and are not necessarily indicative of the financial position that would have been obtained or the financial results that would have occurred if the Propane Transaction and/or Citrus Transaction had been consummated on the dates indicated, nor are they necessarily indicative of the financial position or results of operations in the future. The pro forma adjustments, as described in the accompanying notes, are based upon available information and certain assumptions that are believed to be reasonable as of the date of this document.

Propane Transaction

On October 15, 2011, ETP, Energy Transfer Partners GP, L.P. (“ETP GP”), Heritage ETC, L.P. (“Heritage”) and AmeriGas entered into a Contribution and Redemption Agreement (the “Agreement”). Pursuant to the Agreement, ETP has agreed to contribute to AmeriGas the subsidiaries which operate ETP’s retail propane business, consisting of Heritage Operating, L.P. and Titan Energy Partners, L.P. (the “Propane Business”), in exchange for consideration of approximately $2.9 billion.

The initial consideration consisted of $1.5 billion in cash (the “Cash Consideration”) and common units of AmeriGas valued at $1.32 billion at the time of execution (the “Equity Consideration”), plus the assumption of certain liabilities of the Propane Business as specified in the Agreement.

On December 29, 2011, ETP and AmeriGas submitted to the Federal Trade Commission, or the FTC, an agreement in principle pursuant to which ETP and AmeriGas agreed to amend the Agreement. This amendment, which remains subject to FTC approval, provides that, immediately prior to the closing of the propane business contribution, ETP will cause Heritage Operating, L.P., or HOLP, to transfer HOLP’s interest in the assets of HOLP’s 20-pound propane cylinder exchange business to a wholly owned subsidiary of ETP. The amendment also contemplates that, promptly after the execution of the amendment, ETP will use its best efforts to sell the cylinder exchange business to a third party. Under the terms of the amendment, the purchase price under the Agreement will be reduced by an amount equal to $40 million, subject to a customary post-closing adjustment pursuant to the terms of the Agreement.

Consummation of the Propane Transaction is subject to customary conditions, including, without limitation, (i) the expiration or early termination of the waiting period applicable to the consummation of the Propane Transaction under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”); (ii) the absence of any law, order or injunction prohibiting the Propane Transaction and the related transactions; and (iii) the increase in the amount of loan commitments under AmeriGas’s credit facility to a maximum aggregate amount of $500 million and the approval of certain other amendments to its revolving credit agreement. AmeriGas’s obligation to consummate the Propane Transaction is also conditioned on AmeriGas obtaining debt financing in an amount not less than the Cash Consideration on certain agreed upon terms. On January 5, 2012, AmeriGas announced the pricing by its finance subsidiaries of a public offering of $550.0 million of 6.75% senior notes due 2020 and $1.0 billion of 7.0% senior notes due 2022. AmeriGas’ ability to consummate the debt financing will be subject to customary closing conditions and, should AmeriGas be unable to consummate its pending notes offering, there can be no assurance that AmeriGas will be able to secure other debt financing in accordance with terms at least as favorable to AmeriGas as such agreed upon terms or at all. Subject to such conditions, the Propane Transaction is expected to close in January 2012.

One of ETP’s closing deliverables under the Agreement is that ETP enters into and delivers a support agreement with AmeriGas to provide contingent, residual support of intercompany debt that mirrors the terms of AmeriGas’ senior notes priced on January 5, 2012 (with maturity terms not to exceed 12 months) to finance the cash portion of the purchase price. The support agreement will provide a limited, indirect guarantee of AmeriGas’ senior notes. The support agreement will incorporate by reference certain covenants for ETP’s benefit contained in the indenture governing the outstanding series of AmeriGas’ senior notes, which include items limiting liens, additional indebtedness, sale and leaseback transactions, and asset sales, among other restrictions.

Citrus Transaction

On July 19, 2011, Energy Transfer Equity, L.P. (“ETE”), which owns the general partner of ETP, entered into a Second Amended and Restated Agreement and Plan of Merger (the “Second Amended SUG Merger Agreement”) with Sigma Acquisition Corporation, a Delaware corporation and wholly owned subsidiary of ETE (“Merger Sub”), and Southern Union Company, a Delaware corporation (“SUG”).

Under the terms of the Second Amended SUG Merger Agreement, Merger Sub will merge with and into SUG, with SUG continuing as the surviving entity and becoming a wholly owned subsidiary of ETE (the “SUG Merger”), subject to certain conditions to closing.

Consummation of the SUG Merger is subject to customary conditions, including, without limitation: (i) the adoption of the Second Amended SUG Merger Agreement by the stockholders of SUG, which was obtained on December 9, 2011, (ii) the expiration or early termination of the waiting period applicable to the SUG Merger under the HSR Act, and any required approvals thereunder, (iii) the effectiveness of a registration statement on Form S-4 relating to the common units of ETE to be issued in the SUG Merger, which occurred on October 27, 2011 and (iv) the absence of any law, injunction, judgment or ruling prohibiting or restraining the SUG Merger or making the consummation of the SUG Merger illegal. ETE and SUG have made filings with the Missouri Public Service Commission and expect to receive its approval in the first quarter of 2012.

On July 19, 2011, ETP entered into an Amended and Restated Agreement and Plan of Merger with ETE, SUG and certain of their respective subsidiaries (the “Amended Citrus Merger Agreement”). Under the Amended Citrus Merger Agreement, it is anticipated that SUG will cause the contribution to ETP of a 50% interest in Citrus Corp., which owns 100% of the Florida Gas Transmission pipeline system and is currently jointly owned by SUG and El Paso Corporation (the “Citrus Transaction”). The Citrus Transaction will be affected through the merger of Citrus ETP Acquisition, L.L.C., a Delaware limited liability company and wholly owned subsidiary of ETP, with a wholly owned subsidiary of SUG that indirectly owns a 50% interest in Citrus Corp. In exchange for the interest in Citrus Corp., SUG will receive approximately $2.0 billion, consisting of $1.895 billion in cash and $105 million of ETP common units. In connection with this transaction, ETE has agreed to relinquish its rights to approximately $220 million of the incentive distributions from ETP that ETE would otherwise be entitled to receive over 16 consecutive quarters following the closing of the Citrus Transaction.

Consummation of the Citrus Transaction is subject to customary conditions, including, without limitation: (i) satisfaction or waiver of the closing conditions set forth in the Second Amended SUG Merger Agreement, (ii) the receipt by ETP of any necessary waivers or

amendments to its credit agreement, (iii) the amendment of ETP’s partnership agreement to reflect the agreed upon relinquishment by ETE of incentive distributions from ETP discussed above, and (iv) the absence of any order, decree, injunction or law prohibiting or making the consummation of the transactions contemplated by the Amended Citrus Merger Agreement illegal. The Amended Citrus Merger Agreement contains certain termination rights for both ETE and ETP, including among others, the right to terminate if the Citrus Transaction is not completed by December 31, 2012 or if the Second Amended SUG Merger Agreement is terminated.

The Citrus Transaction is subject to certain risks, which include, but are not limited to risks related to the integration of the acquired assets with ETP’s current operations.

Pursuant to the Amended Citrus Merger Agreement, ETE has granted ETP the right of first offer with respect to any disposition by ETE or SUG of Southern Union Gas Services, a subsidiary of SUG that owns and operates a natural gas gathering and processing system serving the Permian Basin in west Texas and New Mexico.

NOTES TO UNAUDITED PRO FORMA INFORMATION

The unaudited pro forma condensed consolidated statements of operations also include adjustments to equity in earnings of affiliates to reflect net impact of (i) ETP’s proportionate share of limited partners’ interest in net income attributable to AmeriGas and (ii) amortization of the pro forma excess fair value associated with ETP’s interest in AmeriGas. For purposes of the unaudited pro forma condensed consolidated statements of operations, ETP’s equity in the earnings of AmeriGas is calculated by applying a one-quarter lag to the limited partners’ interest in net income attributable to AmeriGas, due to the timing of availability of financial information. Accordingly, ETP’s equity in earnings of AmeriGas reflected in its unaudited pro forma condensed consolidated statements of operations for the nine months ended September 30, 2011 and the year ended December 31, 2010 are based on the earnings of AmeriGas for the nine months ended June 30, 2011 and the twelve months ended September 30, 2010, respectively.
