SunocoCorp to Move SUNC Common Units From NYSE to Texas Stock Exchange

What happened

SunocoCorp LLC approved the voluntary withdrawal of its common units from listing on the New York Stock Exchange and the transfer of that listing to the Texas Stock Exchange, according to a Form 8-K filed with the SEC on September 10, 2026.

The filing says the company expects listing and trading of the common units on the NYSE to end at market close on October 2, 2026, and trading to begin on the TXSE at market open on October 5, 2026. The ticker symbol, SUNC, will not change.

The company also issued a press release dated September 10, 2026 about the transfer, attached to the filing as Exhibit 99.1 and disclosed under Regulation FD. The filing states the decision was approved on September 3, 2026.

SUNC closed at $81.18 on the event date, down 1.46% from the previous close of $82.38, according to the price data.

The filing does not state why the company decided to move the listing.

What this means

SunocoCorp LLC is registered as a petroleum refining business and is organized as a limited liability company rather than a corporation. What trades on the exchange is not stock but common units representing limited liability company interests. A unit works much like a share: it represents an ownership stake, and its holders are members of the LLC rather than shareholders of a corporation. The company's managing member is SunocoCorp Management LLC.

The filing is a Form 8-K, a current report that public companies file with the SEC when something material happens between quarterly reports. Companies do not file an 8-K on a fixed schedule; they file one when an event listed in the form's numbered items occurs, and they must file within four business days of the event. The item numbers in the header of this filing show which triggers were used.

Item 3.01 is the trigger for notice of a delisting, a failure to meet a continued listing rule or standard, or a transfer of a listing. That last category is what applies here. The units are not being delisted in the sense of losing a listing and becoming untradeable; the listing is moving from one exchange to another. Item 3.01 exists so investors learn about a change in where a security trades while it is still pending.

Item 7.01 is Regulation FD disclosure. Regulation FD, or Fair Disclosure, is an SEC rule requiring that when a company gives material information to certain outside parties, it must also make that information public rather than letting selected investors hear it first. Filing the press release under Item 7.01 is how the company satisfies that obligation. Item 9.01 is the exhibit list.

One detail of Item 7.01 is worth noting. The filing states that information furnished under this item is not deemed "filed" for purposes of Section 18 of the Exchange Act and is not automatically incorporated by reference into other filings. That means the press release is made public but does not carry the same legal liability as the rest of the report. Companies routinely use Item 7.01 for this purpose.

The Texas Stock Exchange is a newer exchange, and this filing treats it as the destination venue for the units. The filing does not say what prompted the move, and nothing in the provided sources explains the company's reasoning, so that question is left open here.

The sequence to watch is set out in the filing itself: NYSE trading ends at market close on October 2, 2026, and TXSE trading begins at market open on October 5, 2026. Because the ticker is unchanged, the practical change for anyone holding or tracking the units is the exchange on which they trade, not the symbol.
