Item 1.02 Termination of a Material Definitive Agreement.

In connection with the consummation of the Merger (defined below), on December 5, 2019, SemGroup Corporation, a Delaware corporation (the “Company” or “SemGroup”), terminated all commitments under that certain Amended and Restated Credit Agreement (as amended, supplemented or otherwise modified, the “Credit Agreement”) dated as of September 30, 2016 among SemGroup, as borrower, a syndicate of banks and financial institutions, as lenders, and Wells Fargo Bank, National Association, as administrative and collateral agent. In connection with the termination of the Credit Agreement, on December 5, 2019, all outstanding obligations for principal, interest and fees under the Credit Agreement were paid off in full and all liens securing any obligations under the Credit Agreement were released.

Item 2.01. Completion of Acquisition or Disposition of Assets.

On December 5, 2019, Energy Transfer LP, a Delaware limited partnership (“ET”), completed the acquisition of the Company, pursuant to the terms of the Agreement and Plan of Merger, dated as of September 15, 2019 (the “Merger Agreement”), by and among the Company, ET and Nautilus Merger Sub LLC, a Delaware limited liability company and a wholly owned subsidiary of ET (“Merger Sub”). Under the terms of the Merger Agreement, Merger Sub merged with and into the Company (the “Merger”), with the Company surviving the Merger as a direct wholly owned subsidiary of ET.

At the effective time of the Merger on December 5, 2019 (the “Effective Time”), each share of the Company’s Class A Common Stock, par value $0.01 per share (the “Common Stock”), issued and outstanding immediately prior to the Effective Time was converted into the right to receive (x) $6.80 in cash, without interest (the “Per Share Cash Amount”) and (y) 0.7275 (the “Exchange Ratio”) of a common unit representing a limited partner interest in ET (the “ET Common Units” and together with the Per Share Cash Amount, the “Merger Consideration”). No fractional ET Common Units were issued in the Merger, and the Company’s stockholders received cash in lieu of fractional ET Common Units.

The issuance of ET Common Units in connection with the Merger was registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to ET’s registration statement on Form S-4 (File No. 333-234080), declared effective by the Securities and Exchange Commission (the “SEC”) on October 30, 2019. The Company’s proxy statement/prospectus (the “Proxy Statement/Prospectus”) included in ET’s registration statement contains additional information about the Merger.

The foregoing description of the Merger and the Merger Agreement and the transactions contemplated thereby is not complete and is subject to and qualified in its entirety by reference to the Merger Agreement, a copy of which is attached hereto as Exhibit 2.1 and is incorporated herein by reference.

Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

In connection with the consummation of the Merger, the New York Stock Exchange (the “Exchange”) was notified that each outstanding share of the Company’s Common Stock was converted into the right to receive the Merger Consideration described above, subject to the terms and conditions of the Merger Agreement. SemGroup requested that the Exchange file a notification of removal from listing on Form 25 with the SEC with respect to the delisting of the Company’s shares of Common Stock. The Company’s Common Stock ceased being traded following the close of trading on December 4, 2019 and will no longer be listed on the Exchange. Furthermore, the Company intends to file with the SEC a Form 15 requesting that the reporting obligations of the Company under Sections 13(a) and 15(d) of the Exchange Act be suspended.

Item 3.03. Material Modification to Rights of Security Holders.

The information set forth in Items 2.01, 3.01 and 5.01 of this Current Report on Form 8-K is incorporated by reference into this Item 3.03.

Pursuant to the terms of the Merger Agreement, each share of the Company’s Common Stock issued and outstanding immediately prior to the Effective Time was converted into the right to receive the Merger Consideration as described above. At the Effective Time, holders of the Company’s shares of Common Stock ceased to have any rights as stockholders of the Company, other than the right to receive the Merger Consideration as set forth above.


SemGroup equity awards were treated as follows in connection with the Merger:

  Each award of SemGroup restricted share units, vested or unvested (other than those held by non-employee directors of SemGroup) (a “SemGroup RSU Award”), that was outstanding immediately prior to the Effective Time was assumed by ET and converted into a restricted unit award to receive a number of ET Common Units (an “Assumed RSU Award”) equal to the number of shares of Common Stock subject to such SemGroup RSU Award immediately prior to the Effective Time multiplied by a ratio equal to the Per Share Cash Amount divided by the closing price of one ET Common Unit on the Exchange on the date prior to the closing date plus the Exchange Ratio, rounded up or down to the nearest whole ET Common Unit. Each Assumed RSU Award (i) is otherwise subject to same terms and conditions as were applicable to the corresponding original SemGroup RSU Award and (ii) will fully accelerate upon a termination without “cause,” for “good reason” or as a result of the holder’s death or disability.

  Each award of SemGroup restricted stock (other than those held by non-employee directors of SemGroup) (a “SemGroup Restricted Stock Award”) that was outstanding immediately prior to the Effective Time was assumed by ET and converted into a restricted unit award representing a contractual right upon vesting to receive a number of ET Common Units (an “Assumed Restricted Stock Award”) equal to the product obtained by multiplying (x) the number of shares of Common Stock subject to such SemGroup Restricted Stock Award immediately prior to the Effective Time by (y) the Exchange Ratio, rounded up or down to the nearest whole ET Common Unit. Each Assumed Restricted Stock Award (i) is otherwise subject to the same terms and conditions as were applicable to the corresponding original SemGroup Restricted Stock Award and (ii) will fully accelerate upon a termination without “cause,” for “good reason” or as a result of the holder’s death or disability.

  Each award of SemGroup restricted stock and SemGroup restricted share units held by a non-employee director of SemGroup was fully vested and settled with shares of SemGroup’s Common Stock prior to consummation of the Merger. As of the Effective Time, such shares of SemGroup’s Common Stock converted into the right to receive the Merger Consideration pursuant to the terms of the Merger Agreement.

  Each award of SemGroup performance share units was fully vested with performance deemed achieved at target and settled with shares of SemGroup’s Common Stock prior to consummation of the Merger. As of the Effective Time, such shares of SemGroup’s Common Stock converted into the right to receive the Merger Consideration pursuant to the terms of the Merger Agreement.

Item 5.01. Changes in Control of Registrant.

As a result of the Merger, a change of control of SemGroup occurred on December 5, 2019, and SemGroup is now a direct wholly owned subsidiary of ET.

The information in Item 2.01, 3.03 and 5.02 is incorporated herein by reference.

Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

At the Effective Time, each member of the Company’s board of directors resigned from the board and ceased to be directors of the Company. The members of the Company’s board immediately prior to the Effective Time were Ronald A. Ballschmiede, Sarah M. Barpoulis, Carlin G. Conner, Karl F. Kurz, James H. Lytal, William J. McAdam and Thomas R. McDaniel. None of these resignations were a result of any disagreement with the Company, its management or its board of directors.

Effective on December 5, 2019, Kelcy L Warren and Thomas E. Long were elected to the Company’s board of directors pursuant to the terms of the Merger Agreement.

Also at the Effective Time, each of the Company’s existing officers, including Carlin G. Conner, Robert N. Fitzgerald, Susan S. Lindberg, Timothy R. O’Sullivan, Thomas F. DeLorbe and Thomas D. Sell, were replaced with officers of Merger Sub pursuant to the terms of the Merger Agreement.

Effective on December 5, 2019, Kelcy L Warren was appointed Chief Executive Officer of the Company and Thomas E. Long was appointed Chief Financial Officer of the Company.

With respect to each of Messrs. Warren and Long, there are no arrangements or understandings between such director and any other persons pursuant to which he will serve as a director (other than the Merger Agreement). Mr. Warren is the Chief Executive Officer and Chairman of the general partner of ET and the Chief Executive Officer and Chairman of the general partner of Energy Transfer Operating, L.P., a Delaware limited partnership and a subsidiary of ET (“ETO”). Mr. Long is the Chief Financial Officer of the general partner of ET and the Chief Financial Officer of the general partner of ETO. There are no relationships between Messrs. Warren and Long and the Company or any related person of the Company that would require disclosure pursuant to Item 404(a) of Regulation S-K.

Item 5.07. Submission of Matters to a Vote of Security Holders.

On December 4, 2019, the Company held a special meeting of stockholders (the “Special Meeting”) in Tulsa, Oklahoma to consider certain proposals related to the Merger Agreement. A total of 79,606,089 shares of Common Stock were entitled to vote as of October 25, 2019, the record date for the Special Meeting (the “Record Date”). There were 63,809,553 shares of Common Stock present, in person or by proxy, at the Special Meeting (or 82.7% of the outstanding shares of Common Stock). As of the Record Date, there were 350,000 shares of the Company’s Series A Cumulative Perpetual Convertible Preferred Stock (“Preferred Stock”) outstanding. Holders of shares of Preferred Stock were entitled to vote together with the holders of shares of Common Stock as a single class. Each holder of shares of Preferred Stock was entitled to a number of votes equal to the number of votes such holder would have had if all shares of Preferred Stock held by such holder had been converted into shares of Common Stock as of the Record Date. As of the Record Date, the outstanding shares of Preferred Stock were convertible into an aggregate of 11,987,820 shares of Common Stock and such amount represented an equal number of votes that holders of Preferred Stock were entitled to cast, in person or by proxy, at the Special Meeting. Giving effect to the Preferred Stock on an as-converted basis, there were 11,646,578 shares of Preferred Stock present, in person or by proxy, at the Special Meeting.

DRAFT V.3

Energy Transfer and SemGroup Announce Successful Completion of Merger

Energy Transfer Expands Vast Pipeline Network and

Acquires Strategic Position on the Houston Ship Channel

DALLAS and TULSA, OK, December 5, 2019 — Energy Transfer LP (NYSE: ET) and SemGroup Corporation (NYSE: SEMG) today announced the completion of their previously announced merger, which resulted in the acquisition of Tulsa-based SemGroup by Dallas-based Energy Transfer. The terms of the agreement were approved by the holders of a majority of SemGroup’s outstanding voting stock at a special meeting of SemGroup stockholders on December 4, 2019. As a result of the merger, Energy Transfer issued approximately 57.6 million of its common units to SemGroup stockholders.

Effective with the opening of the market today, SemGroup will cease to be a publicly traded company and its common stock will discontinue trading on the NYSE.

The combined operations of the two companies are expected to generate annual run-rate efficiencies of more than $170 million, consisting of commercial and operational synergies of $80 million, financial savings of $50 million and cost savings of $40 million.

Energy Transfer’s acquisition of SemGroup’s Houston Fuel Oil Terminal (HFOTCO) strengthens its crude oil transportation, terminalling and export capabilities, and provides Energy Transfer a strategic position on the Houston Ship Channel. HFOTCO is a world-class crude oil terminal with more than 18 million barrels of crude oil storage capacity, five deep-water ship docks and seven barge docks.

To provide shippers further access from the Houston Ship Channel to markets along the Gulf Coast, Energy Transfer is constructing the Ted Collins pipeline, a 75-mile crude line that will connect HFOTCO to Energy Transfer’s Nederland terminal. The pipeline is expected to be in service in 2021, and will have an initial capacity of 500 [thousand] barrels per day.

This acquisition expands Energy Transfer’s pipeline footprint by adding crude oil and NGL gathering systems and transmission lines in the DJ Basin in Colorado and the Anadarko Basin in Oklahoma and Kansas with connections to crude oil terminals in Cushing, Oklahoma. The acquisition will also provide a significant natural gas gathering and processing presence in the Alberta Basin in western Canada.


Energy Transfer LP (NYSE: ET) owns and operates one of the largest and most diversified portfolios of energy assets in the United States, with a strategic footprint in all of the major domestic production basins. ET is a publicly traded limited partnership with core operations that include complementary natural gas midstream, intrastate and interstate transportation and storage assets; crude oil, NGL and refined product transportation and terminalling assets; NGL fractionation; and various acquisition and marketing assets. ET, through its ownership of Energy Transfer Operating, L.P., also owns Lake Charles LNG Company, as well as the general partner interests, the incentive distribution rights and 28.5 million common units of Sunoco LP (NYSE: SUN), and the general partner interests and 46.1 million common units of USA Compression Partners, LP (NYSE: USAC). For more information, visit the Energy Transfer LP website at www.energytransfer.com.

SemGroup Corporation moves energy across North America through a network of pipelines, processing plants, refinery-connected storage facilities and deep-water marine terminals with import and export capabilities. SemGroup serves as a versatile connection between upstream oil and gas producers and downstream refiners and end users. Key areas of operation and growth include western Canada, the Mid-Continent and the Gulf Coast. SemGroup is committed to safe, environmentally sound operations.
