EXPLANATORY NOTE

This Amendment No. 10 to Schedule 13D amends and supplements the Schedule 13D originally filed with the United States Securities and Exchange Commission (the “SEC”) on February 1, 2016 (as amended, the “Schedule 13D”), relating to the common units representing limited partner interests in the Issuer (the “Common Units”) of Summit Midstream Partners, LP (the “Issuer”). Capitalized terms used herein without definition shall have the meaning set forth in the Schedule 13D.

 

Item 4.

Purpose of Transaction.

Item 4 of the Schedule 13D is hereby amended and supplemented as follows:

Purchase Agreement

On May 28, 2020 (the “Closing Date”), pursuant to a purchase agreement, dated as of May 3, 2020 (the “Purchase Agreement”), by and among the Issuer, and the parties thereto, the Issuer purchased all the outstanding limited liability company interests of Summit Midstream Partners, LLC (“Summit Investments”), which is the sole member of Summit Midstream Partners Holdings, LLC (“SMP Holdings”), which in turn owns (a) 45,318,866 Common Units and (b) the right of SMP Holdings to receive the deferred purchase price obligation under the contribution agreement by and between the Issuer and SMP Holdings, dated February 25, 2016, as amended, in exchange for approximately $28.2 million in cash and warrants for the purchase of up to an aggregate of 8,059,609 Common Units issued to SMP TopCo, LLC.

Also pursuant to the Purchase Agreement, the Issuer purchased 5,915,827 Common Units held by SMLP Holdings, LLC (“SMLP”), in exchange for approximately $6.8 million in cash and warrants for the purchase of up to an aggregate of 1,940,391 Common Units issued to SMLP (together with warrants for the purchase of up to an aggregate of 8,059,609 Common Units, the “Warrants”).

As a result of these transactions, Summit Investments became a wholly owned subsidiary of the Issuer. Further pursuant to the Purchase Agreement, on the Closing Date, each of Mr. Peter Labbat, Mr. Chris Leininger, Mr. Matthew Delaney, Mr. Francesco Ciabatti and Mr. Thomas Lane resigned from the board of directors of Summit Midstream Partners GP, LLC, the general partner of the Issuer.

The exercise price under the Warrants is $1.023 per Common Unit. The Warrants provided that the Issuer will file a registration statement to register the Common Units issuable upon exercise of the Warrants no later than 90 days following the Closing Date and use commercially reasonable efforts to cause such registration statement to become effective.

On November 10, 2020, the Issuer effected a 1-for-15 reverse stock split. As a result, the Warrants were then exercisable for the purchase of an aggregate of 666,667 Common Units at a strike price of $15.345 per Common Unit.


CUSIP No. 866142102    13D    Page 10 of 15 pages

 

The foregoing description of the Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of such agreement, which is attached as an exhibit to this Schedule 13D and is incorporated herein by reference.

Conversion of Warrants and Distribution

On August 5, 2021, each of SMP TopCo, LLC and SMLP effected a cashless exercise of the Warrants and received 334,028 Common Units and 80,419 Common Units, respectively.

In September 2021, SMP TopCo, LLC voluntarily dissolved and, in connection with the dissolution, SMP TopCo, LLC made a liquidating distribution of the Common Units as follows: 5,136 Common Units to Energy Capital Partners II, LP (“ECP II”), 167,307 Common Units to Energy Capital Partners II-A, LP (“ECP II-A”), 76,267 Common Units to Energy Capital Partners II-B IP, LP (“ECP II-B”), 61,539 Common Units to Energy Capital Partners II-C (Summit IP), LP (“ECP II-C”), and 20,870 Common Units to Energy Capital Partners II (Summit Co-Invest), LP (“ECP Summit Co-Invest” and together with ECP II, ECP II-A, ECP II-B and ECP II-C, the “ECP Funds”).

General

The Reporting Persons acquired the securities pursuant to the transactions as described in this Schedule 13D. The Reporting Persons currently intend to sell all of the Common Units now held in the open market or in privately negotiated transactions. Other than as described, the Reporting Persons do not currently have any plans or proposals that relate to, or would result in, any of the matters listed in Items 4(a)–(j) of Schedule 13D, although, depending on the factors discussed herein, the Reporting Persons may change their purpose or formulate different plans or proposals with respect thereto at any time.

Item 5 of this Schedule 13D is hereby amended and restated in its entirety as follows:

(a) – (b)

The following sets forth, as of the date of this Schedule 13D, the aggregate number of Common Units and percentage of Common Units beneficially owned by each of the Reporting Persons, as well as the number of Common Units as to which each Reporting Person has the sole power to vote or to direct the vote, shared power to vote or to direct the vote, sole power to dispose or to direct the disposition of, or shared power to dispose or to direct the disposition of, as of the date hereof, based on 6,744,926 Common Units outstanding as of August 1, 2021, as reported in the Issuer’s quarterly report on Form 10-Q filed with the SEC on August 9, 2021:
