Advantage Announces First Quarter 2013 Results

Solid Operating and Financial Results Supports Development Plan to Double Production at Glacier

(TSX: AAV, NYSE: AAV)

CALGARY, May 9, 2013 /PRNewswire/ - Advantage Oil & Gas Ltd. ("Advantage" or the "Corporation") is pleased to announce the financial and operating results for the three months ended March 31, 2013. The following press release summarizes and discusses the unconsolidated financial and operating highlights for Advantage (excludes Longview Oil Corp).

Stable Production, Increased Funds from Operations and Reduced Bank Indebtedness

• On April 30, 2013, Advantage announced that it had closed the Questfire Energy Corp. ("Questfire") transaction which constituted the sale of substantially all of Advantage's non-core assets. Accordingly, all financial and operating results in the first quarter of 2013 include results from the non-core assets.
• Funds from operations for the first quarter of 2013, excluding dividends received from Longview Oil Corp. ("Longview"), was $21.5 million or $0.13 per share, an increase of 27% as compared to the fourth quarter of 2012 and an increase of 73% as compared to the second quarter of 2012. Funds from operations improved significantly due to an increase in realized natural gas prices. Advantage's realized natural gas price contains deductions for TransCanada pipeline firm service transportation commitments including costs for any unutilized service at Glacier.
• The tax-free dividend income received from Longview amounted to $3.2 million ($0.02 per share) during the first quarter of 2013 as a result of Advantage's 45.1% ownership in the common shares of Longview.
• Production during the first quarter of 2013 averaged 21,257 boe/d (93% natural gas) and was comparable to the fourth quarter of 2012. Production during the second quarter of 2013 will include production from the non-core assets for the month of April 2013.
• Advantage's average royalty rate was 4.5% for the first quarter of 2013 compared to 7.9% during the same period of 2012. Advantage's royalty rates have decreased due to lower average royalties attributed to production from Glacier.
• Operating expense for the three months ended March 31, 2013 was $5.18/boe ($0.86/mcf) compared to $5.74/boe during the same period of 2012. The reduction in operating costs reflects the continued efficiencies created by processing our natural gas production through our 100% owned Glacier gas plant.
• Total capital expenditures for the three months ended March 31, 2013 was incurred primarily at Glacier and amounted to $54.1 million. During the first quarter of 2013, we employed revised completion designs and completed 7 Upper Montney wells and 2 Lower Montney wells which remained from our previous 2011/2012 drilling season. In addition, 3 new Middle Montney wells which were drilled in the second half of 2012 were completed during the fourth quarter 2012 and first quarter of 2013. Productivity from these wells is anticipated to maintain Glacier production at approximately 100 mmcf/d for the remainder of 2013. Capital expenditures also included modifications to increase the water disposal capacity at our Glacier gas plant and included the drilling of a water disposal well which will further reduce operating costs.
• As of March 31, 2013, bank indebtedness was $164.0 million on a $300 million credit facility. Concurrent with the closing of our non-core asset sales on April 30, 2013, we announced that our credit facility was revised to $230 million with a pro-forma bank debt of approximately $125 million as of March 31, 2013. This leaves an undrawn credit facility of $105 million or 46% of our current credit facility.
• In addition to Glacier, Advantage's other major assets includes a 45.1% ownership in the shares of Longview valued at approximately $101 million, a $32.6 million Convertible Senior Secured Questfire Debenture and 1,500,000 Class B Shares of Questfire.
• Advantage's pro-forma tax pools as of December 31, 2012 are approximately $1.1 billion of which approximately $800 million are deductible at a rate of 100%.

Looking Forward - Focused on Glacier Development Plan to Double Production by 2015

• On April 30, 2013, Advantage announced the closing of the Questfire Transaction which represents substantially all of Advantage's remaining non-core assets. Advantage is now a pure play company focused on our signature Glacier Montney property.
• We are currently working on the two year development plan that will increase natural gas throughput at Glacier to approximately 140 mmcf/d by the spring of 2014 and 200 mmcf/d by the spring of 2015. Preliminary estimates for this plan is included in our current investor presentation that is available on our website. Capital requirements will be funded through growing cash flow, undrawn credit facilities and current Advantage investments. Operational activities will include drilling of additional Upper Montney wells and further delineation of the Middle and Lower Montney intervals where only 2.2% and 27.6% of the total acreage, respectively, has been assigned reserves at year end 2012. Options to process and extract liquids from the Middle Montney will also be evaluated and included in the development plan.
• We anticipate announcing our capital program and budget for the period July 1, 2013 to June 30, 2014 before mid-year 2013.

Commodity Hedging Program

• Advantage has entered into a number of natural gas hedges in support of our two year Glacier development plan. Our natural gas hedges will reduce the volatility of future cash flows for the period from January 2013 to March 2016 and are summarized in the following table:

With respect to forward-looking statements contained in this press release, Advantage has made assumptions regarding: conditions in general economic and financial markets; effects of regulation by governmental agencies; current commodity prices and royalty regimes; future exchange rates; royalty rates; future operating costs; availability of skilled labor; availability of drilling and related equipment; timing and amount of capital expenditures; the impact of increasing competition; the price of crude oil and natural gas; that the Corporation will have sufficient cash flow, debt or equity sources or other financial resources required to fund its capital and operating expenditures and requirements as needed; that the Corporation's conduct and results of operations will be consistent with its expectations; that the Corporation will have the ability to develop the Corporation's crude oil and natural gas properties in the manner currently contemplated; current or, where applicable, proposed assumed industry conditions, laws and regulations will continue in effect or as anticipated; and the estimates of the Corporation's production and reserves volumes and the assumptions related thereto (including commodity prices and development costs) are accurate in all material respects.

These forward-looking statements are made as of the date of this press release and Advantage disclaims any intent or obligation to update publicly any forward-looking statements, whether as a result of new information, future events or results or otherwise, other than as required by applicable securities laws.

References in this press release to initial production test rates, initial "productivity", initial "flow" rates, "flush" production rates and "behind pipe production" are useful in confirming the presence of hydrocarbons, however such rates are not determinative of the rates at which such wells will commence production and decline thereafter and are not indicative of long term performance or of ultimate recovery. While encouraging, readers are cautioned not to place reliance on such rates in calculating the aggregate production for Advantage.

Barrels of oil equivalent (boe) may be misleading, particularly if used in isolation. A boe conversion ratio has been calculated using a conversion rate of six thousand cubic feet of natural gas to one barrel of oil. A boe conversion ratio of 6 mcf:1 bbls is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. Given that the value ratio based on the current price of crude oil as compared to natural gas is significantly different from the energy equivalency of 6:1, utilizing a conversion on a 6:1 basis may be misleading as an indication of value.

The Corporation discloses several financial measures that do not have any standardized meaning prescribed under IFRS. These financial measures include funds from operations and cash netbacks. Management believes that these financial measures are useful supplemental information to analyze operating performance and provide an indication of the results generated by the Corporation's principal business activities. Investors should be cautioned that these measures should not be construed as an alternative to net income, cash provided by operating activities or other measures of financial performance as determined in accordance with IFRS. Advantage's method of calculating these measures may differ from other companies, and accordingly, they may not be comparable to similar measures used by other companies.
