<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Arial" style="font-size:11.0pt;">Suncor recorded second quarter 2017 operating earnings of $199&nbsp;million ($0.12 per common share) compared to a $565&nbsp;million operating loss ($0.36 per common share) in the prior year quarter. Highlights of the quarter included improved crude oil pricing, increased production from E&amp;P and R&amp;M, and continued focus on costs in all areas. Results in the current period were impacted by a facility incident at Syncrude occurring late in the first quarter of 2017 and planned maintenance at the majority of the company&#146;s Oil Sands assets. Results in the prior year period were impacted by production being shut in as a result of forest fires in the Fort McMurray area, partially offset by an R&amp;M first-in, first-out&nbsp;gain.</font></p>

Net earnings for the second quarter of 2017 included an unrealized after-tax foreign exchange gain of $278&nbsp;million on the revaluation of U.S.&nbsp;dollar denominated debt, an after-tax charge of $10&nbsp;million for early payment of debt, net of associated realized foreign currency hedge gains, and a non-cash after-tax loss of $32&nbsp;million on forward interest rate swaps and foreign currency derivatives.

Excluding these two factors, total operating, selling and general expense was lower in the current quarter as controllable cost savings more than offset an increase in energy input costs that resulted from higher natural gas&nbsp;prices.</font></p>

Although the ramp-up following the turnaround at Firebag was longer than anticipated, the extension of this turnaround cycle to five years has provided an overall net benefit to the company through the experience gained, which will be leveraged during future turnaround cycles. Production at Oil Sands operations returned to normal operating rates by the end of the&nbsp;quarter.</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Arial" style="font-size:11.0pt;">Oil Sands operations cash operating costs per barrel were $27.80 in the second quarter of 2017, reflecting major maintenance in the period and the positive impact of the company&#146;s cost reduction initiatives, compared to $46.80 in the prior year quarter. The quarter-over-quarter improvement was primarily due to the increased production and lower controllable costs.</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Arial" style="font-size:11.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Arial" style="font-size:11.0pt;">Suncor&#146;s share of Syncrude production was 61,000&nbsp;bbls/d in the second quarter of 2017, compared to 35,600&nbsp;bbls/d in the prior year quarter. The increase is attributed to the negative impact of the forest fires during the second quarter of 2016 combined with an additional working interest acquired partway through the second quarter of 2016. Production in the second quarter of 2017 was significantly impacted by a facility incident that occurred late in the first quarter of 2017, a planned upgrader turnaround and the advancement of coker maintenance originally planned for the fourth quarter of 2017, which was accelerated to coincide with the unplanned outage in an effort to maximize annual production. Syncrude cash operating costs per barrel in the second quarter of 2017 were $97.80, a decrease from $113.55 in the prior year quarter, with both periods being impacted by the previously noted production outages. Syncrude has completed the required facility repairs and the planned upgrader turnaround and expects to return to normal operating rates by early August, following the completion of coker maintenance.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Arial" style="font-size:11.0pt;">Production volumes in E&amp;P increased to 125,500&nbsp;boe/d in the second quarter of 2017, compared to 117,600&nbsp;boe/d in the prior year quarter, primarily due to lower planned maintenance at Terra Nova, production from new wells at Hibernia and production from Libya, partially offset by natural declines at&nbsp;Buzzard.</font></p>
<p style="margin:0in 0in .0001pt;"><font size="2" face="Arial" style="font-size:11.0pt;">&nbsp;</font></p>
<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Arial" style="font-size:11.0pt;">Overall production guidance for 2017 remains unchanged as increased production from E&amp;P is expected to offset the impact of the facility incident at&nbsp;Syncrude.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Arial" style="font-size:11.0pt;">Strong operational performance contributed to increased refinery crude throughput of 435,500&nbsp;bbls/d, compared to 400,200&nbsp;bbls/d in the prior year quarter, and also reflected lower planned maintenance and improved crude availability. Average refinery utilization in the second quarter of 2017 was 94%, compared with 87% in the prior year quarter. Results in R&amp;M also benefited from strong retail sales volumes in the second quarter of 2017, contributing to a year-to-date record for the first half of&nbsp;2017.</font></p>

<p style="font-size:11.0pt;margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Arial"><font style="font-size:11.0pt;">Fort Hills project construction was 90% complete at the end of the second quarter of 2017, with turnover of the ore processing and main primary extraction assets to operations occurring in the period. Activity in the quarter also included the utilities plant entering into the completion and turnover to operations phase. Construction at the secondary extraction facility, which is the final area to be completed to bring the project to first oil, continued in the quarter, and the project remains on target to start production at the end of 2017. Expenditures in the second quarter of 2017 were also focused on</font>  </font>early-works sustaining activities that will support the execution of the Fort Hills mine and tailings plan following the commencement of production. Subsequent to the end of the quarter, the company commissioned the East Tank Farm Development and will begin readying the terminal for the receipt of Fort Hills bitumen at the end of&nbsp;2017.</p>

<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Arial" style="font-size:11.0pt;">The Hebron project achieved a major milestone in the second quarter of 2017, with the platform towed out to its final offshore location and successfully positioned on the sea floor. Drilling activities at Hebron are on schedule, and first oil remains on track for late 2017. Activity in the second quarter in E&amp;P also included continued development drilling at Hibernia and White Rose and development work on the Norwegian Oda&nbsp;project.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Arial" style="font-size:11.0pt;">Syncrude sustaining capital in the second quarter of 2017 was primarily focused on the planned upgrader turnaround, advanced coker maintenance previously scheduled for the fourth quarter of 2017 and repairs associated with the facility incident from the first quarter of 2017. The company expects to receive insurance proceeds to offset a significant portion of the expenditures associated with the facility incident.</font></p>

<p style="margin:0in 0in .0001pt;text-autospace:none;"><font size="2" face="Arial" style="font-size:11.0pt;">Suncor has updated its production, capital and other information in its 2017 corporate guidance, previously issued on April&nbsp;26, 2017. The full year outlook for Syncrude production has been updated from 135,000&nbsp;&#150; 150,000&nbsp;bbls/d to 130,000&nbsp;&#150; 145,000&nbsp;bbls/d, and the full year outlook range for Syncrude cash operating costs has been updated from $36.00&nbsp;&#150; $39.00/bbl to $42.00&nbsp;&#150; $45.00/bbl, to reflect the extended return to operations following the facility incident that occurred late in the first quarter of 2017. In addition, the full year outlook range for E&amp;P production has been updated from 110,000&nbsp;&#150; 120,000&nbsp;boe/d to 115,000&nbsp;&#150; 125,000&nbsp;boe/d due to improved asset performance, resulting in no change to the full year outlook range for total Suncor production.</font></p>
