Legal Proceedings Regarding the Merger with Tallgrass Energy GP, LP

As previously disclosed, on March 26, 2018, Tallgrass Energy GP, LP, a Delaware limited partnership (“TEGP”), Tallgrass Equity, LLC, a Delaware limited liability company (“Tallgrass Equity”), Tallgrass Energy Partners, LP, a Delaware limited partnership (“TEP”), Razor Merger Sub, LLC, a Delaware limited liability company and wholly owned subsidiary of TEP (“Merger Sub”), and Tallgrass MLP GP, LLC, a Delaware limited liability company (“TEP GP”), entered into a definitive Agreement and Plan of Merger (“Merger Agreement”). Subject to the satisfaction or waiver of certain conditions in the Merger Agreement, Merger Sub will merge with and into TEP, with TEP surviving the merger as a wholly owned subsidiary of Tallgrass Equity and its subsidiaries (the “Merger”). At the effective time of the Merger, each issued and outstanding common unit representing a limited partner interest in TEP (collectively, the “TEP Common Units”), except for any TEP Common Units held by Tallgrass Equity, Tallgrass Equity Investments, LLC, a wholly owned subsidiary of Tallgrass Equity, or TEP, will be converted into the right to receive 2.0 Class A shares representing limited partner interests in TEGP (collectively, the “TEGP Class A Shares”).

On May 18, 2018, TEP filed a definitive proxy statement (the “Proxy Statement”) with the Securities and Exchange Commission (“SEC”) for the solicitation of proxies in connection with the special meeting of TEP’s unitholders to be held on June 26, 2018 to consider and vote on a proposal to approve the Merger Agreement and the Merger.

As previously described in the Proxy Statement, in April 2018, two public common unitholders of TEP filed separate lawsuits under the federal securities laws in the United States District Court for the District of Delaware challenging the sufficiency of the disclosures made in the registration statement on Form S-4 filed by TEGP, of which the Proxy Statement forms a part, in connection with the Merger. These cases are captioned Leadford v. Tallgrass Energy Partners, LP, et al., Case No. 1:18-cv-00545-RGA (D. Del.) (the “Leadford Action”) and Dake v. Tallgrass Energy Partners, LP, et al., Case No. 1:18-cv-00580-RGA (D. Del.) (the “Dake Action”). The Leadford Action is asserted on behalf of a putative class of holders of TEP Common Units other than those held by Tallgrass Equity, Tallgrass Equity Investments, LLC or TEP, while the Dake Action is brought only on behalf of the named plaintiff.

Both actions allege violations of Sections 14(a) and 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 14a-9 promulgated thereunder based on various alleged omissions of material information from the registration statement on Form S-4 filed by TEGP, of which the Proxy Statement forms a part. The Leadford Action names as defendants TEP and each of TEP GP’s directors, individually. It seeks to compel TEP to issue revised disclosures, to enjoin the Merger, damages, and an award of costs and attorneys’ and experts’ fees. On April 24, 2018, the plaintiff in the Leadford Action filed a motion for preliminary injunction seeking to enjoin the TEP unitholder vote to approve the Merger. The Dake Action names as defendants TEP and each of TEP GP’s directors, individually. It seeks to enjoin the Merger (or, in the alternative, rescission or an award of rescissory damages in the event the Merger is completed), to compel TEP to issue revised disclosures, a declaration that the defendants violated Sections 14(a) and 20(a) of the Exchange Act and Rule 14a-9 promulgated thereunder, and an award of costs and attorneys’ and experts’ fees. On May 21, 2018, the plaintiff in the Dake Action filed a motion for a preliminary injunction seeking to enjoin the TEP unitholder vote to approve the Merger.

In order to moot what TEP considers to be unmeritorious disclosure claims, alleviate the costs, risks and uncertainties inherent in litigation and provide additional information to its unitholders, TEP has determined to voluntarily supplement the Proxy Statement as described in this Current Report on Form 8-K. Nothing in this Current Report on Form 8-K shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. To the contrary, TEP specifically denies all allegations in the foregoing complaints, including without limitation that any additional disclosure was or is required. As a result of the supplemental disclosures set forth herein, plaintiffs in the Leadford Action and the Dake Action have agreed to withdraw their motions for a preliminary injunction.

SUPPLEMENT TO THE DEFINITIVE PROXY STATEMENT

TEP is providing additional information regarding the Proxy Statement to its unitholders. These disclosures should be read in connection with the Proxy Statement, which should be read in its entirety. To the extent that the information set forth herein differs from or updates information contained in the Proxy Statement, the information set forth herein shall supersede or supplement the information in the Proxy Statement. Defined terms used but not defined herein have the meanings set forth in the Proxy Statement. Without admitting in any way that the disclosures below are material or otherwise required by law, TEP makes the following amended and supplemental disclosures (with additional language in bold and underlined text below):
