Tallgrass Energy Partners Announces Follow-On Public Offering of Common Units

Tallgrass Energy Partners, LP (NYSE:TEP) (“TEP” or the “Partnership”) announced today the commencement, subject to market conditions, of an underwritten public offering of 10,000,000 common units representing limited partner interests. The Partnership also intends to grant the underwriters a 30-day option to purchase up to an additional 1,500,000 common units.

TEP intends to use the net proceeds from the offering to fund a portion of the consideration for the potential acquisition from a subsidiary of Tallgrass Development of an additional 33.3% interest in Tallgrass Pony Express Pipeline, LLC (“Pony Express”). The potential acquisition would increase TEP’s ownership of Pony Express to 66.7%. No definitive transaction agreement for the potential acquisition of an interest in Pony Express has been executed at this time and the proposed transaction remains subject to final review, negotiations and approval by the conflicts committee and the board of directors of TEP’s general partner. Pending the use of proceeds for such purpose, TEP intends to use the net proceeds of the offering to repay borrowings under TEP’s revolving credit facility with any excess to be used for general partnership purposes.

BofA Merrill Lynch, Deutsche Bank Securities, Barclays, Citigroup, Credit Suisse, Goldman, Sachs & Co., Morgan Stanley, RBC Capital Markets and Wells Fargo Securities are acting as the joint book-running managers for the offering. BBVA, Capital One Securities and Regions Securities are acting as the co-managers for the offering.

The common units will be offered and sold pursuant to an effective shelf registration statement previously filed with the Securities and Exchange Commission. This press release does not constitute an offer to sell or the solicitation of an offer to buy the securities described herein, nor shall there be any sale of these securities in any state or jurisdiction in which such an offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.
