On December 27, 2018, American Midstream Partners, L.P., a Delaware limited partnership (the “Partnership”) entered into that certain Second Amendment to Second Amended and Restated Credit Agreement (the “Amendment”) with American Midstream, LLC, a Delaware limited liability company (the “AMID Borrower”), Blackwater Investments, Inc., a Delaware corporation (together with the AMID Borrower, the “Borrowers”), the other Loan Parties party thereto, the Lenders party thereto and Bank of America, N.A., as Administrative Agent, to that Second Amended and Restated Credit Agreement, dated as of March 8, 2017 (as amended, supplemented or otherwise modified from time to time prior to the date of the Amendment, the “Original Credit Agreement”), among the Borrowers, the Partnership, the Lenders party thereto, and the Administrative Agent.

The Amendment amends the Original Credit Agreement to, among other things:

As a result of the amendment described in the second bullet above, the Partnership is not permitted to declare or pay any cash distributions until its Consolidated Total Leverage Ratio is reduced to less than 5.00:1.00, as shown in the Compliance Certificate required to be delivered together with audited financial statements for the most recently completed fiscal year and unaudited financial statements for the most recently completed quarter. Therefore, the Partnership does not expect to make any cash distributions on its common units or preferred units with respect to the fourth quarter of 2018.

The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the Amendment, which will be filed with the Partnership’s Annual Report on Form 10-K for the year ending December 31, 2018. Any capitalized terms used but not defined herein have the meanings ascribed thereto in the Amendment or the Original Credit Agreement, as the context may require.

This Current Report includes “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended, including statements related to the Partnership’s expectations distributions. We have used the words “expect,” “intend,” “may,” “would,” “plan” and similar terms and phrases to identify forward-looking statements. Although we believe the assumptions upon which these forward-looking statements are based are reasonable, any of these assumptions could prove to be inaccurate and the forward-looking statements based on these assumptions could be incorrect. Many of the factors that will determine these results are beyond our ability to control or predict. These factors include the risk factors described in Part I, Item 1A. in our Annual Report on Form 10-K for the year ended December 31, 2017, filed with the SEC on April 9, 2018, and our other filings with the SEC. All future written and oral forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the previous statements. The forward-looking statements herein speak as of the date of this press release. We undertake no obligation to update such statements for any reason, except as required by law.
