Nostrum Oil & Gas PLC

Nostrum Oil & Gas Finance B.V. and Nostrum Oil & Gas B.V. have extended the expiration date of their tender offer for senior secured notes to 5:00 p.m. New York City time on September 2, 2026, from the previous deadline of August 21, 2026. The extension follows the announcement on August 17, 2026, that the issuer entered into a sale and purchase agreement to sell its participating interests in Zhaikmunai LLP and POSITIV Invest LLP, along with rights under certain related loan agreements, to Altaris Holding Ltd., which is owned by Fincraft Energy Holding Limited and Alturion Holding Limited. The offeror considers the sale may constitute a material change with respect to the tender offer, and the extension provides additional time for eligible holders to consider the offer. Valid tender instructions previously received and not validly withdrawn do not need to be resubmitted, and all other terms and conditions of the tender offer remain unchanged.
