On July 9, 2026, MV Oil Trust (the “Trust”) issued a press release announcing that, because the payment of the previously announced distribution of $0.593844 per unit payable July 24, 2026 to unitholders of record as of July 15, 2026 (the “Trust distribution”) represents more than 25% of the price of the Trust units when announced, The New York Stock Exchange (“NYSE”) has advised the Trust that the Trust units will trade with “due bills” representing an assignment of the right to receive the Trust distribution from the record date of July 15, 2026 through the closing of trading on the NYSE on July 24, 2026, which is the payment date and the last day of trading before the July 27, 2026 suspension date (this period of time representing the “Dividend Right Period”).

Unitholders who sell their Trust units during the Dividend Right Period (July 15, 2026 through July 24, 2026) will be selling their right to the Trust distribution, and such unitholders will not be entitled to receive the Trust distribution on July 24, 2026. Due bills obligate a seller of Trust units to deliver the Trust distribution payable on such Trust units to the buyer (the “Dividend Right”).

 The Trust distribution record date of July 15, 2026 will be used as the date for establishing the due bill tracking of the Dividend Right to the holder of Trust units. Due bill obligations are customarily settled between the brokers representing the buyers and the sellers of securities. The Trust has no obligation for either the amount of the due bill or the processing of the due bill. Buyers and sellers of the Trust units should consult their brokers before trading to be sure they understand the effect of the NYSE’s due bill procedures.
