Item 8.01 Other Events.

On June 29, 2026, Global Partners LP (NYSE: GLP) (the “Partnership”) issued a notice of full redemption to the holders of the Partnership’s Series B Fixed Rate Cumulative Redeemable Perpetual Preferred Units (NYSE: GLP pr B) (CUSIP No. 37946R307) (the “Series B Preferred Units”) notifying such holders that the Partnership intends to redeem all of its issued and outstanding Series B Preferred Units on July 30, 2026 (the “Redemption Date” and such redemption, the “Redemption”). After the Redemption, Series B Preferred Units will no longer be outstanding and all rights of the holders of Series B Preferred Units will terminate, except the right of such holders to receive the Redemption Price (as defined below). Furthermore, because all of the issued and outstanding shares of Series B Preferred Units are being redeemed, trading of the Series B Preferred Units on the New York Stock Exchange will cease prior to market open on the Redemption Date.

The redemption price will be equal to $25.00 per redeemed Series B Preferred Unit, plus an amount equal to all unpaid and accrued distributions thereon to, but excluding, the Redemption Date, less any applicable tax withholding as required by law (the “Redemption Price”), which will be payable in cash on the Redemption Date. All of the Series B Preferred Units are maintained in book-entry form registered in the name of The Depository Trust Company or its nominee and will be redeemed in accordance with the applicable procedures of The Depository Trust Company or such nominee.

Equiniti Trust Company, LLC is acting as the redemption agent for the Redemption and its address is: 28 Liberty Street, 53^rd Floor, New York, New York 10005, Attn: Corporate Actions.

This report does not constitute a notice of redemption of the Series B Preferred Units and this report does not constitute an offer to sell or buy or the solicitation of an offer to buy or sell any security. This report contains forward-looking statements as defined under the federal securities laws, including statements regarding the Redemption and amounts to be used for the Redemption. Although management believes that expectations reflected in such forward-looking statements are reasonable, no assurance can be given that such expectations will prove to be correct. In addition, these statements are subject to certain risks, uncertainties and other assumptions that are difficult to predict and may be beyond our control. If any of these risks or uncertainties materialize, or if underlying assumptions prove incorrect, the Partnership’s actual results may vary materially from what management forecasted, anticipated, estimated, projected or expected.
