Note 12 — Contingencies

Legal Proceedings

We and the Partnership are parties to various legal, administrative and regulatory proceedings that have arisen in the ordinary course of our business. We and the Partnership are also parties to various proceedings with governmental environmental agencies, including, but not limited to the U.S. Environmental Protection Agency (the “EPA”), Texas Commission on Environmental Quality, Oklahoma Department of Environmental Quality, New Mexico Environment Department, Louisiana Department of Environmental Quality and North Dakota Department of Environmental Quality, which assert monetary sanctions for alleged violations of environmental regulations, including air emissions, discharges into the environment and reporting deficiencies, related to events that have arisen at certain of our facilities in the ordinary course of our business.

On July 24, 2023, we received a Notice of Violation (the “New Mexico NOV”) from the New Mexico Environment Department (the “NMED”), Air Quality Bureau, relating to alleged air permit violations at the Red Hills gas processing facility. The alleged air permit violations occurred primarily between August 1, 2021 and June 30, 2022, while the facility was owned by Lucid Energy Delaware, LLC (“Lucid”), a subsidiary we acquired in July 2022 and renamed Targa Northern Delaware LLC. On December 5, 2024, we received a proposed Administrative Compliance Order (the “ACO”) from the NMED relating to the violations identified in the New Mexico NOV and certain other alleged violations. The ACO includes a proposed civil penalty of approximately $47.8 million and requires certain capital improvements to address the operations and excess air emissions at the Red Hills processing facility. These capital improvements, totaling approximately $140 million, were substantially completed by December 31, 2024.

On January 3, 2025, we filed a Request for Hearing with the NMED with respect to the ACO. We have cooperated with the NMED in identifying and correcting legacy environmental issues since our acquisition of Lucid, and we expect to continue to engage with the NMED to resolve this matter. Although this matter is ongoing and we cannot predict its ultimate outcome, we believe we have valid defenses to many of the NMED allegations and intend to vigorously defend this matter.

On October 26, 2023, we received a final judgment in a lawsuit alleging a breach of contract related to the major winter storm in February 2021. The damages awarded against us are approximately $6.9 million, not including pre-judgment interest. Both parties are appealing the judgment. We were named as defendants in other breach of contract cases related to force majeure events arising during the major winter storm in February 2021. These cases were settled by the parties for an aggregate amount of approximately $12.7 million, not including pre-judgment interest.

In April 2024, we received an administrative Notice of Violation (the “EPA NOV”) from the EPA and a request for the production of documents from the United States Attorney’s Office for North Dakota relating to alleged violations of the Clean Air Act (“CAA”), at certain Targa Badlands LLC compressor stations. The EPA NOV and subpoena stem from inspections the EPA conducted at the compressor stations on June 15, 2023, as well as related records reviews. In October 2024, we began negotiations with the U.S. Attorney’s Office with respect to resolution of a single-count information alleging a violation of the CAA related to untimely installation of monitoring equipment at one compressor station, which carries a maximum fine of $500,000, and we entered into a Plea Agreement on December 16, 2024 reflecting these terms. In early July 2025, we entered into a Consent Agreement and Final Order with the EPA that

resolves the allegations contained in the EPA NOV by requiring, among other things, payment of an administrative penalty in the amount of approximately $3.2 million.
