December 14, 2017

HOUSTON–(BUSINESS WIRE)–American Midstream Partners, LP (NYSE: AMID) (the “Partnership”)
announced today the pricing of $125 million aggregate principal amount
of 8.50% Senior Notes due 2021 at an offering price equal to 102.375% of
par. The notes are an additional issue of the Partnership’s outstanding
8.50% Senior Notes due 2021, which were issued in an aggregate principal
amount of $300 million on December 28, 2016. The two offerings comprise
total aggregate principal amount outstanding of $425 million and, except
for notes sold pursuant to Regulation S under the Securities Act of
1933, as amended (the “Securities Act”), the notes will trade under the
existing CUSIP numbers.

The Partnership expects the offering to close on December 19, 2017,
subject to the satisfaction of customary closing conditions, and expects
to use the net proceeds from the offering to reduce borrowings under its
revolving credit facility. As of September 30, 2017, after giving effect
to the offering and the use of proceeds therefrom, the Partnership would
have had approximately $290 million of available liquidity to meet its
strategic growth objectives.

The notes have not been registered under the Securities Act, or any
state securities laws. Unless so registered, the securities may not be
offered or sold in the United States except pursuant to an exemption
from, or in a transaction not subject to, the registration requirements
of the Securities Act and applicable state securities laws.

The notes have been offered and sold to qualified institutional buyers
in the United States pursuant to Rule 144A under the Securities Act, and
to persons, other than U.S. persons, outside of the United States
pursuant to Regulation S under the Securities Act.

This press release is being issued pursuant to Rule 135c under the
Securities Act, and is neither an offer to sell nor a solicitation of an
offer to purchase the notes or any other securities, and shall not
constitute an offer to sell, a solicitation of an offer to buy, or a
sale of, the notes or any other securities in any state or jurisdiction
in which such an offer, solicitation or sale would be unlawful.
