A Delaware court has ruled on a significant merger dispute involving American Midstream GP, LLC, now known as Third Coast Midstream Holdings, LLC. The case, Craig W. Thomas v. American Midstream GP, LLC n/k/a Third Coast Midstream Holdings, LLC, was decided on September 11, 2026, and it addresses the validity of a merger that many former unitholders contested. This ruling is crucial as it impacts how conflicts of interest are managed in corporate governance, particularly in the energy sector.

The case centers around the merger of American Midstream Partners, LP, a master limited partnership (MLP) that owned various midstream energy assets, and its general partner, American Midstream GP, LLC. The merger raised questions about whether the general partner acted in the best interests of the partnership and its unitholders, especially given the financial struggles the partnership faced leading up to the merger.

The plaintiff, Craig W. Thomas, a former unitholder, argued that the general partner failed to uphold its duties under the partnership's limited partnership agreement (LPA). The dispute arose after the general partner sought approval for the merger from a conflicts committee, which is designed to ensure that such transactions are handled fairly and transparently. The case eventually made its way to the Delaware Court of Chancery, where it was heard by Vice Chancellor Zurn.

The court's ruling focused on whether the conflicts committee granted special approval for the merger in good faith. The court found that the conflicts committee members believed the merger was in the best interests of the partnership. The opinion stated, "The plaintiff has failed to rebut the presumption that special approval was granted in good faith and effective." This ruling suggests that the court upheld the validity of the conflicts committee's approval process.

The court's decision emphasized the importance of the conflicts committee's role in overseeing transactions that involve potential conflicts of interest. The ruling highlighted that the committee was composed of independent members who acted with due diligence. The court noted that the committee had taken substantial steps to evaluate the merger, including hiring independent financial advisors and conducting extensive meetings to discuss the implications of the merger.

This ruling has significant implications for corporate governance, particularly for MLPs and similar entities. It reinforces the idea that conflicts committees can provide a shield against judicial review if they act in good faith and follow the proper procedures outlined in the partnership agreements. The court's decision could set a precedent for how similar cases are handled in the future, particularly in the energy sector where mergers and acquisitions are common.

Going forward, this ruling may affect how partnerships and their general partners approach transactions that involve conflicts of interest. It underscores the necessity for independent oversight and thorough evaluation processes to ensure that all parties' interests are adequately protected. The ruling may also influence how unitholders and investors view the governance structures of MLPs and similar entities.

As for what’s next, the ruling can potentially be appealed, although details were not available in the court filing. The outcome of this case may also influence related cases involving corporate governance and fiduciary duties in the energy sector.
