PENGROWTH ENTERS INTO AGREEMENT TO SELL REMAINING SWAN HILLS ASSETS FOR $185 MILLION

(Calgary, April 25, 2017) – Pengrowth Energy Corporation (the “Company” or “Pengrowth”) today announced that it has entered into an agreement for the sale of the remaining portion of its Swan Hills assets in North Central Alberta for total cash consideration of $185 million, subject to customary closing conditions and adjustments.

The divested assets generated average daily production of approximately 5,150 barrels of oil equivalent per day (boe per day) (weighted approximately 94 percent towards liquids) during the fourth quarter of 2016 and had Proved plus Probable reserves of 21.0 million boe assigned to them as at December 31, 2016, according to the independent reserve evaluators GLJ Petroleum Consultants Ltd.

This transaction essentially completes Pengrowth’s exit from the Swan Hills area and provides the company with additional financial flexibility to further reduce indebtedness. When combined with the $522 million of proceeds from the previously announced Lindbergh GORR, Swan Hills and Bernadet asset sales, the $185 million of proceeds from this sale of the remaining Swan Hills assets result in total disposition proceeds of $707 million to date in 2017.

The effective date of the sale is January 1, 2017 and closing is expected to occur on May 31, 2017, subject to the receipt of all necessary regulatory approvals and the satisfaction of other customary closing conditions.

The Company expects to use the proceeds from this sale to further reduce its indebtedness, including prepaying the remaining outstanding US $100 million (equivalent Cdn $134 million) of the 6.35% senior term notes which are scheduled to mature on July 26, 2017. The prepayment is expected to be completed before the end of the second quarter following which the Company will have no further term debt due until August 2018.

Upon closing of all announced dispositions and application of proceeds to debt repayment, Pengrowth’s debt would fall to approximately Cdn $700 million, representing a decline in debt levels of approximately 60 percent since December 31, 2016.

The sale of the remaining Swan Hills assets is expected to impact full year 2017 average production guidance by approximately 3,400 boe per day, resulting in revised 2017 production to be between 43,500 and 45,500 boe per day. The remaining changes to 2017 guidance resulting from the sale are outlined in the table below:

	Previous Guidance		Date Guidance
Average daily production (boe per day)	47,000 to 49,000		43,500 to 45,500
Total capital expenditures ($ millions)		125		125
Funds flow from operations1 ($ millions)		170		160

2017 Hedging Update

Prior to the recent strengthening in crude oil prices, Pengrowth elected to cancel its 2017 light oil risk management contracts it had in place and presently has no oil production hedged. The Company also entered into new natural gas risk management contracts to provide downside protection against potential declines in natural gas prices. As at March 31, 2017, the Company had the following risk management contracts in place for the remainder of 2017:

Natural Gas		Q2, 2017		Q3 2017		Q4 2017

Advisory Regarding Reserves and Production Information

All reserves  and production information herein is based upon Pengrowth’s company interest (Pengrowth’s working interest share of reserves or production plus Pengrowth’s royalty interest, being Pengrowth’s interest in production and payment that is based on the gross production at the wellhead), before deduction of royalty obligations and using GLJ’s January 1, 2017 forecast prices and costs as disclosed herein. Numbers presented may not add due to rounding.

Caution Regarding Engineering Terms:

When used herein, the term "boe" means barrels of oil equivalent on the basis of one boe being equal to one barrel of oil or NGLs or 6,000 cubic feet of natural gas (6 mcf: 1 bbl). Barrels of oil equivalent may be misleading, particularly if used in isolation. A conversion ratio of six mcf of natural gas to one boe is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead.
