Suncor has amended such Tender Offers to increase the previously announced Pool 1 Maximum Amount from C$700,000,000 aggregate purchase price, excluding accrued and unpaid interest, to C$1,000,000,000 aggregate principal amount and the Pool 2 Maximum Amount from C$100,000,000 aggregate purchase price, excluding accrued and unpaid interest, to C$100,000,000 aggregate principal amount. All other terms of the Tender Offers as previously announced in the offer to purchase dated September 19, 2024 (as amended and supplemented hereby, the "Offer to Purchase") remain unchanged. Suncor refers investors to the Offer to Purchase for the complete terms and conditions of the Tender Offers.

As of the previously announced early tender date and time of 5:00 p.m., New York City time, on October 2, 2024 (the "Early Tender Date"), according to information provided by Global Bondholder Services Corporation, in its capacity as information agent and tender agent for the Tender Offers for the US$ Notes (as defined below), and Computershare Investor Services Inc., in its capacity as tender agent for the Tender Offers for the C$ Notes (as defined below), the aggregate principal amount of each series of Notes listed in the table below had been validly tendered and not validly withdrawn in each Tender Offer. Withdrawal rights for the Notes expired at 5:00 p.m., New York City time, on the Early Tender Date.

1. The 6.50% Notes due 2038, 6.80% Notes due 2038, 6.00% Notes due 2042, 5.35% Notes due 2033 and 5.95% Notes due 2035 are referred to herein as the "US$ Notes." The 3.10% Series 6 Medium Term Notes due 2029, 3.00% Series 5 Medium Term Notes due 2026, 5.00% Series 7 Medium Term Notes due 2030 and 5.39% Series 4 Medium Term Notes due 2037 are referred to herein as the "C$ Notes."
2. Subject to the Maximum Amounts and proration, if applicable, the principal amount of each series of Notes that is purchased in each Tender Offer will be determined in accordance with the applicable Acceptance Priority Level (in numerical priority order) specified in this column in the manner described in the Offer to Purchase.
3. C$1,000,000,000 represents the maximum aggregate principal amount being purchased in respect of the Pool 1 Notes that may be purchased in the Tender Offers. C$100,000,000 represents the maximum aggregate principal amount being purchased in respect of the Pool 2 Notes that may be purchased in the Tender Offers. For purposes of calculating the portion of the Maximum Amounts attributable to each series of US$ Notes, the aggregate principal amount of US$ Notes tendered in the applicable Tender Offer shall be converted to Canadian dollars based on the exchange rate of one U.S. dollar for Canadian dollars, as shown on the FXC page displayed on the Bloomberg Pricing Monitor at 11:00 a.m., New York City time, on the Price Determination Date (as defined below).
4. Such Notes were issued by Petro-Canada; Suncor assumed the obligations for such Notes in 2009.
5. Such Notes were issued by Canadian Oil Sands Limited; Suncor assumed the obligations for such Notes in 2016.

The terms and conditions of the Tender Offers are described in the Offer to Purchase. Suncor expects to elect to exercise its right to make payment on October 7, 2024 (the "Early Settlement Date") for Notes validly tendered prior to or at the Early Tender Date and accepted for purchase. Suncor intends to fund the purchase of validly tendered and accepted Notes on the Early Settlement Date with cash on hand.

Because the Pool 1 Notes validly tendered and not validly withdrawn prior to or at the Early Tender Date have an aggregate principal amount that is expected to exceed the Pool 1 Maximum Amount, Suncor does not expect to accept for purchase all Pool 1 Notes that have been validly tendered and not validly withdrawn prior to or at the Early Tender Date. Rather, subject to the Pool 1 Maximum Amount and the Acceptance Priority Levels set forth in the table above, in each case as further described in the Offer to Purchase, Suncor expects to accept for purchase all of the 6.50% Notes due 2038 validly tendered and not validly withdrawn prior to or at the Early Tender Date. Suncor expects to accept for purchase the 6.80% Notes due 2038 validly tendered and not validly withdrawn prior to or at the Early Tender Date on a prorated basis using a proration factor to be announced following the determination of the Total Consideration (as defined below). As described further in the Offer to Purchase, Notes tendered and not accepted for purchase will be promptly credited to the tendering holder's account. Additionally, because the Pool 1 Notes validly tendered and not validly withdrawn prior to or at the Early Tender Date have an aggregate principal amount that is expected to exceed the Pool 1 Maximum Amount, Suncor does not expect to accept for purchase any Pool 1 Notes tendered after the Early Tender Date on a subsequent settlement date. The Tender Offers for the Pool 1 Notes will expire at 5:00 p.m., New York City time, on October 18, 2024, or any other date and time to which Suncor extends the applicable Tender Offer, unless earlier terminated.

Because the Pool 2 Notes validly tendered and not validly withdrawn prior to or at the Early Tender Date have an aggregate principal amount that is expected to exceed the Pool 2 Maximum Amount, Suncor does not expect to accept for purchase all Pool 2 Notes that have been validly tendered and not validly withdrawn prior to or at the Early Tender Date. Rather, subject to the Pool 2 Maximum Amount and the Acceptance Priority Levels set forth in the table above, in each case as further described in the Offer to Purchase, Suncor expects to accept for purchase all of the 3.10% Series 6 Medium Term Notes due 2029, 3.00% Series 5 Medium Term Notes due 2026 and 5.35% Notes due 2033 validly tendered and not validly withdrawn prior to or at the Early Tender Date. Suncor expects to accept for purchase the 5.95% Notes due 2035 validly tendered and not validly withdrawn prior to or at the Early Tender Date on a prorated basis using a proration factor to be announced following the determination of the Total Consideration. Suncor does not expect to accept for purchase any 5.00% Series 7 Medium Term Notes due 2030 or 5.39% Series 4 Medium Term Notes due 2037. As described further in the Offer to Purchase, Notes tendered and not accepted for purchase will be promptly credited to the tendering holder's account. Additionally, because the Pool 2 Notes validly tendered and not validly withdrawn prior to or at the Early Tender Date have an aggregate principal amount that is expected to exceed the Pool 2 Maximum Amount, Suncor does not expect to accept for purchase any Pool 2 Notes tendered after the Early Tender Date on a subsequent settlement date. The Tender Offers for the Pool 2 Notes will expire at 5:00 p.m., New York City time, on October 18, 2024, or any other date and time to which Suncor extends the applicable Tender Offer, unless earlier terminated.

The applicable U.S. consideration (the "U.S. Total Consideration") offered per US$1,000 principal amount of each series of US$ Notes validly tendered prior to or at the Early Tender Date and accepted for purchase pursuant to the applicable Tender Offer will be determined in the manner described in the Offer to Purchase by reference to the applicable fixed spread plus the applicable yield based on the bid-side price of the applicable U.S. reference security as displayed on the applicable Bloomberg Reference Page at 11:00 a.m., New York City time, on October 3, 2024 (the "Price Determination Date"). The applicable Canadian consideration (the "Canadian Total Consideration" and, together with the U.S. Total Consideration, the "Total Consideration") offered per C$1,000 principal amount of each series of C$ Notes validly tendered prior to or at the Early Tender Date and accepted for purchase pursuant to the applicable Tender Offer will be determined in the manner described in the Offer to Purchase by reference to the applicable fixed spread plus the applicable yield based on the bid-side price of the applicable Canadian reference security as displayed on the applicable Bloomberg Reference Page at 11:00 a.m., New York City time, on the Price Determination Date. Only holders of Notes who validly tendered and did not validly withdraw their Notes prior to or at the Early Tender Date are eligible to receive the applicable Total Consideration, which is inclusive of the applicable early tender payment, for Notes accepted for purchase. Holders will also receive accrued and unpaid interest on Notes validly tendered and accepted for purchase from the applicable last interest payment date up to, but not including, the Early Settlement Date.

Promptly following the Price Determination Date, Suncor will issue a news release specifying, among other things, (i) the aggregate principal amount of each series of Notes validly tendered and not validly withdrawn as of the Early Tender Date and expected to be accepted for purchase in each Tender Offer, (ii) the proration factor for the 6.80% Notes due 2038 and the 5.95% Notes due 2035 and (iii) the Total Consideration for each series of Notes expected to be accepted for purchase.

All Notes accepted for purchase will be retired and cancelled and will no longer remain outstanding obligations of Suncor.

The Tender Offers are subject to the satisfaction or waiver of certain conditions, which are specified in the Offer to Purchase. The Tender Offers are not conditioned on any minimum principal amount of Notes being tendered.
