(“NuVista” or the “Company”) (TSX:NVA) is pleased to announce record-setting reserves, financial and operating results for the three months and year ended December 31, 2022, and to provide an update on a number of key strategic initiatives. The results of our 2022 program demonstrate the quality and capacity of our asset base to deliver outsized returns and the ability of our team to do so in a disciplined manner, while remaining focused upon safety and sustainability. We enter 2023 financially strong, and in a position to continue our program of returning capital to our shareholders, reducing debt, and delivering on our value-adding growth strategy concurrently.

Fourth Quarter and Full Year 2022 Operational and Financial Highlights

During the quarter and year ended December 31, 2022, NuVista:

• Achieved our highest ever annual average production rate of 68,690 Boe/d, a 31% increase from 2021 and at the top end of our guidance range of 68,000 – 69,000 Boe/d. Annual production consisted of 33% condensate, 9% NGLs, and 58% natural gas, reaching an average of 74,252 Boe/d for the fourth quarter;
• Generated record annual adjusted funds flow(1) of $892.8 million ($3.94/share, basic(4)), a 178% increase from 2021. This included $257.0 million of adjusted funds flow in the fourth quarter alone;
• Delivered our highest ever free adjusted funds flow(2) of $464.0 million for the year ($2.05/share, basic(4)), a $437.4 million increase from 2021. This included $183.0 million of free adjusted funds flow in the fourth quarter;
• Achieved annual net earnings of $631.0 million ($2.78/share, basic), a 138% increase from 2021;
• Improved our operating netback(3) to $38.33/Boe and corporate netback(3) to $35.60/Boe, an 83% and 112% increase, respectively, from 2021;
• Realized an average natural gas price of $7.39/Mcf, an improvement of 33% compared to the average AECO monthly index price of $5.56/Mcf for the year, as a result of our natural gas diversification strategy;  
• Executed a successful capital expenditure(2) program, investing $419.5 million in well and facility activities including the drilling of 49 gross (47.5 net) wells and the completion of 45 gross (44.4 net) wells in our condensate rich Wapiti Montney play;
• Exited the year with $41.9 million of available cash and zero drawn on our $440 million credit facility. Net debt(1) at year end was $171.8 million, a 64% reduction from $480.2 million at year end 2021 and below the previously announced net debt target of $200 million(5). NuVista’s net debt to annualized fourth quarter adjusted funds flow(1) was 0.2x;
• Repurchased and subsequently cancelled 13.5 million common shares for an aggregate cost of $157.4 million or $11.67/share under the terms of our NCIB. Subsequent to year-end we repurchased and subsequently cancelled an additional 1.0 million common shares, completing 80% of the NCIB;
• Continued to significantly advance our progress in the areas of environmental, social and governance (“ESG”), including the release of our 2021 ESG report, which is available on our Company website. Importantly, the report contains continued evidence of our significant reductions in methane and greenhouse gas (“GHG”) emissions, a journey that we have committed to continuing; and
• Achieved FID approval for a cogeneration project at the NuVista Wembley Gas Plant for startup by early 2024, which will significantly reduce operating costs, fuel consumption, and GHG emissions.

Record Achievements in Reserve Metrics

NuVista is pleased to report the year end 2022 independent evaluation of our reserves by GLJ Ltd. (“GLJ”) (the “GLJ Report”). With the infrastructure investment in our assets now largely behind us, our focus has shifted to building production volumes and maximizing the velocity at which invested capital is returned through exceptional half-cycle returns. The quality of our asset base is reflected in additional positive technical revisions to our production base and the highly efficient growth in reserves. Our established track record of improvement and the depth and quality of running room in our undeveloped reserves reinforce our ability to provide a differentiated level of value creation for our shareholders both short and long term.

Highlights of our 2022 reserves report include the following accomplishments:

• Reported Proved Developed Producing (“PDP”) reserves of 142.7 MMBoe, a year-over-year increase of 17%. Total Proved plus Probable (“TP+PA”) reserves reached 604.4 MMBoe, a year-over-year increase of 7%. This growth in reserves was due in part to new locations being booked in the Lower Montney zone at Gold Creek;
• Replaced 183% and 247% of 2022 production on a PDP and TP+PA basis, respectively, while allocating less than 50% of our adjusted funds flow toward capital expenditures;
• Technical revisions of +3% were achieved on PDP reserves, primarily due to continued well outperformance, particularly in the Pipestone area, which saw a technical revision of +6%;
• Delivered PDP Finding and Development Costs (“F&D”)(1) that exceeded our expectations at $9.09/Boe due to strong well performance and resulting positive technical revisions. TP+PA F&D was robust at $8.38/Boe due to the continued addition of high-quality reserves, positive technical revisions and only seeing an increase in future development capital of 4% due to conservative prior well cost bookings and our continued inflation mitigation efforts;
• Achieved a PDP recycle ratio of 5.0x, based on our 2022 operating netback, excluding realized loss on financial derivative contracts;
• Continued to successfully convert undeveloped locations to production while maintaining total developed and undeveloped well count at 1,418, which includes 306 developed wells, 338 undeveloped TP+PA locations and 774 undeveloped Contingent locations. Our undeveloped inventory represents 25 years of development at our current pace of drilling;
• Increased our PDP before-tax net present value per share, discounted at 10% (NPV10)(2), by 44% to $9.47 at December 31, 2022; and
• Increased our TP+PA NPV10 per share(2) by 46% to $27.93 at December 31, 2022.

Notes:
(1)	Each of “F&D costs”, “recycle ratio”, “operating netback” and “net present value per share ” are non-GAAP financial ratios. See "Oil and Gas Advisories" and "Non-GAAP and Other Financial Measures" in this press release for information relating to these specified financial measures.
(2)	Reference to “net present value per share” is supplementary financial measures. Reference should be made to the section entitled “Non-GAAP and Other Financial Measures” in this press release.

The detailed summary of our year end 2022 reserves disclosure is included below, and further information will be included in our Annual Information Form which will be filed on or before March 30, 2023 at www.sedar.com.

Excellence in Operations

Operations in the field continue to progress successfully as planned. The cadence of the three-rig program has underpinned our ability to manage the inflationary environment that persisted throughout 2022. We are proud that we were successfully able to manage inflationary pressures on our well costs to just 10% in 2022 and are confident that our outlook for 5% incremental inflation in 2023 is achievable. We are beginning to see early signs of cost pressures easing, likely to manifest toward mid-year 2023.

One rig is currently drilling in the Wapiti area while two rigs have moved back into Pipestone and are drilling a 6-well pad. Completion operations are going extremely well. A 5-well pad at Gold Creek has been successfully completed and is currently being tested. A 6-well pad at Elmworth which finished drilling at the end of 2022 is currently being completed.

Well performance and on-stream schedule has continued favorably as planned. IP30 volumes from the 3-well pad at Wapiti (Bilbo Block) which was brought on stream in January averaged 1,525 Boe/d per well, including 60% condensate. This is an important multi-zone pad in the southwest corner of the block that includes a Montney C-Zone well. In addition, a new IP365 milestone has been reached on a 6-well Pad in Pipestone (referenced in NuVista’s Corporate Presentation). This Pad averaged 1,160 Boe/d (including 32% condensate) per well over the first year of production, which is 55% above the historic average production for the area. This is another important datapoint that reinforces our long-term outlook toward continued 3-zone development in the Pipestone area.

Balance Sheet Strength, Rapid Debt Reduction and Return of Capital to Shareholders

As noted in the highlights section, we succeeded in rapidly reducing net debt to below our long term target of less than $200 million during 2022. In 2023, we expect the continued reduction in our net debt but at a moderated rate, as we have increased our rate of return of capital to shareholders.

As a result of achieving our target net debt level, we previously announced an increase of the return of capital to shareholders to approximately 75% of free adjusted funds flow, with the remainder allocated to reducing net debt. We continue to believe that the best method for return of capital to shareholders is initially to repurchase shares, however we will re-evaluate the uses of free adjusted funds flow through 2023 as our growth plan proceeds. This evaluation will consider commodity prices, the economic and tax environment, and will include all options including continued disciplined growth to facility capacity of 105,000 Boe/d, share repurchases, prudent targeted acquisitions or infrastructure repurchases, and dividend payments.

Environment, Social & Governance (“ESG”) Highlights

Approximately 60% of our current production is comprised of natural gas which has the lowest carbon footprint of any hydrocarbon. Our ongoing efforts to reduce GHG emissions led to a 16% reduction in our Scope 1 & 2 GHG intensity for 2021 relative to our 2020 baseline year. This was a significant step in achieving our stated goal of realizing a 20% reduction in GHG intensity by 2025. In August 2022, we released our 2021 ESG report which highlights our performance through 2021. We have made significant progress on our ESG targets and continue to advance projects that support and enhance our objectives. For more information regarding our ESG performance and targets, please refer to our 2021 ESG report which is available on our website at www.nuvistaenergy.com. On June 9, 2022, we successfully incorporated sustainability linked performance features into our credit facility and as a result of our ongoing ESG initiatives, we are on track to meet or exceed these established sustainability performance targets (“SPTs”).

We also progressed in matters of Social and Governance including continued headway on diversity and inclusion on several fronts. More details are available in our 2022 management discussion and analysis and our 2021 ESG report.

2023 Guidance Update

As discussed above, NuVista is pleased to note that operations and performance have been strong while both condensate and natural gas prices have been favorable through 2022. We are in an extremely fortunate position of having top tier assets and economics, and with disciplined execution we have been spending approximately half of free adjusted funds flow on capital to execute our plans. This means that despite the significant moderation of natural gas pricing during the first quarter of 2023, free adjusted funds flow is reduced but still highly positive. We have hedged approximately 35% of projected natural gas production for this summer with floor and ceiling prices of C$4.17/Mcf and $7.31/Mcf (hedged and exported volumes converted to an AECO equivalent price). We have less than 2% exposure to AECO prices this summer due our hedges and our diversified sales portfolio. Due to our high condensate weighting, our execution economics remain very strong. As such, we will continue with our capital execution plans unchanged while still returning free adjusted funds flow to shareholders and reducing net debt.

Full year production and capital spending guidance is reaffirmed at 79,000 – 83,000 Boe/d and $425 to $450 million, respectively. Due to the continued efficiency gains mentioned above and strong well performance our first quarter volumes are still expected to fall within our previous guidance range of 71,000 – 74,000, but likely near the bottom of the range due to unplanned outages at three separate third party midstream facilities which impacted quarterly production by 1,500 Boe/d. All repairs were completed and the facilities are now back online. Daily production levels have currently reached 78,000 Boe/d due to a number of new wells commencing production, however we are temporarily prevented from increasing production further due to the ongoing restrictions on the NGTL pipeline network in the Upstream James River Area. The restrictions are expected to subside through mid-March, and the remaining three quarters of the year are each expected to average well over 80,000 Boe/d.

We intend to continue our track record of carefully directing free adjusted funds flow towards a prudent balance of return to shareholders and debt reduction, while investing in production growth until our existing facilities are filled and debottlenecked to maximum efficiency. NuVista has an exceptional business plan that maximizes free adjusted funds flow and the return of capital to shareholders when our existing facilities are debottlenecked and filled to maximum efficiency at production levels of approximately 100,000 to 105,000 Boe/d. With facilities optimized, returns are enhanced further with corporate netbacks which are expected to grow by approximately $2-$3/Boe due to the efficiencies of scale which will reduce our unit operating, transportation, and interest expenses.

NuVista has top quality assets and a management team focused on relentless improvement. We have the necessary foundation and liquidity to continue adding significant value for our shareholders. We will continue to adjust to the environment in order to maximize the value of our asset base and ensure the long-term sustainability of our business. We would like to thank our staff, contractors, and suppliers for their continued dedication and delivery, and we thank our Board of Directors and our shareholders for their continued guidance and support.

Please note that our corporate presentation will be available at www.nuvistaenergy.com on March 8, 2023. NuVista’s financial statements, notes to the financial statements and management’s discussion and analysis for the year ended December 31, 2022, will be filed on SEDAR (www.sedar.com) under NuVista Energy Ltd. on March 8, 2023 and can also be accessed on NuVista’s website.

NOTE:

(1)

F&D costs and FD&A are used as a measure of capital efficiency. The calculation for F&D costs includes all exploration and development capital for that period as outlined in the Company’s year-end financial statements plus the change in future development capital for that period. This total capital including the change in the future development capital is then divided by the change in reserves for that period including revisions for that same period. The aggregate of the exploration and development costs incurred in the most recent financial year and the change during the year in estimated future development costs generally will not reflect total finding and development costs related to reserve additions for the year. FD&A costs are calculated in the same manner except in addition to exploration and development capital and the change in future development capital, acquisition capital is also included in the calculation.

Summary of Corporate Net Present Value Data

The estimated net present values of future net revenue before income taxes associated with NuVista’s reserves effective December 31, 2022 and based on published 3 Consultants’ Average price forecast as at January 1, 2023 as set forth below are summarized in the following table:

The estimated future net revenue contained in the following table does not necessarily represent the fair market value of the reserves. There is no assurance that the forecast price and cost assumptions contained in the GLJ Report will be attained and variations could be material.

(3)	NuVista’s future realized gas prices are forecasted based on a combination of various benchmark prices in addition to the AECO benchmark in order to reflect the favorable price diversification to other markets which NuVista has undertaken. Pricing at these markets has been accounted for in the GLJ Report. Additional information on NuVista’s gas marketing diversification will be available in our corporate presentation.

Advisories Regarding Oil and Gas Information 

BOEs may be misleading, particularly if used in isolation. A BOE conversion ratio of 6 Mcf: 1 Bbl is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. As the value ratio between natural gas and crude oil based on the current prices of natural gas and crude oil 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.

This press release contains a number of oil and gas metrics prepared by management, including F&D costs, FD&A costs, recycle ratio, reserves replacement and DCET costs, which does not have standardized meanings or standard methods of calculation and therefore such measures may not be comparable to similar measures used by other companies. Such metrics have been included herein to provide readers with additional measures to evaluate NuVista's performance on a comparable basis with prior periods; however, such measures are not reliable indicators of the future performance of NuVista and future performance may not compare to the performance in previous periods. Details of how F&D costs, FD&A costs and recycle ratios are calculated are set forth under the heading “Non-GAAP and Other Financial Measures – Non-GAAP Ratios”. Reserves replacement is calculated as reserves divided by estimated production. DCET includes all capital spent to drill, complete equip and tie-in a well.

Any references in this press release to initial production rates are useful in confirming the presence of hydrocarbons, however, such rates are not determinative of the rates at which such wells will continue production and decline thereafter. While encouraging, readers are cautioned not to place reliance on such rates in calculating the aggregate production for NuVista.

Reference to current strip prices for 2023 in this press release reflect February 15, 2023 pricing: WTI US$77.85/Bbl, NYMEX US$3.20/MMBtu, AECO 7A Index $2.94/GJ, 1.34 CAD:USD FX; 2024 pricing: WTI US$73.51/Bbl, NYMEX US$3.62/MMBtu, AECO $2.95/GJ, 1.33 CAD:USD FX.

This press release discloses NuVista's drilling locations in two categories: (i) undeveloped proved plus probable (2P) drilling locations; and (ii) undeveloped contingent resources (2C) drilling locations. Undeveloped 2P drilling locations are derived from a report prepared by GLJ, NuVista's independent qualified reserves evaluator, evaluating NuVista's reserves as of December 31, 2022 (the "GLJ Report"), and account for undeveloped drilling locations that have associated proved and/or probable reserves, as applicable. Undeveloped 2C drilling locations are derived from a report prepared by GLJ evaluating NuVista's contingent resources as of December 31, 2022 ("GLJ Contingent Resource Report"), and account for undeveloped drilling locations that have associated contingent resources based on a best estimate of such contingent resources. There is no certainty that we will drill all drilling locations and if drilled there is no certainty that such locations will result in additional oil and gas production. The drilling locations on which we actually drill wells will ultimately depend upon the availability of capital, regulatory approvals, seasonal restrictions, oil and natural gas prices, costs, actual drilling results, additional reservoir information that is obtained and other factors. Contingent resources are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from known accumulations using established technology or technology under development, but which are not currently considered to be commercially recoverable due to one or more contingencies. In the case of the contingent resources estimated in the GLJ Contingent Resource Report, contingencies include: (i) further delineation of interest lands; (ii) corporate commitment, and; (iii) final development plan. To further delineate interest lands additional wells must be drilled and tested to demonstrate commercial rates on the resource lands. Reserves are only assigned in close proximity to demonstrated productivity. As continued delineation drilling occurs, a portion of the contingent resources are expected to be reclassified as reserves. Confirmation of corporate intent to proceed with remaining capital expenditures within a reasonable timeframe is a requirement for the assessment of reserves. Finalization of a development plan includes timing, infrastructure spending and the commitment of capital.

Basis of presentationUnless otherwise noted, the financial data presented in this press release has been prepared in accordance with Canadian generally accepted accounting principles (“GAAP”) also known as International Financial Reporting Standards (“IFRS”). The reporting and measurement currency is the Canadian dollar. National Instrument 51-101 - "Standards of Disclosure for Oil and Gas Activities" includes condensate within the product type of natural gas liquids. NuVista has disclosed condensate values separate from natural gas liquids herein as NuVista believes it provides a more accurate description of NuVista's operations and results therefrom.

Production split for Boe/d amounts referenced in the press release are as follows:

Reference	Total Boe/d	Natural Gas%	Condensate%	NGLs%
Q4 2022 production - actual	74,252	58%	34%	8%
Q4 2022 production guidance	72,000 – 74,000	62%	30%	8%
2022 annual production - actual	68,690	58%	33%	9%
2022 annual production guidance	68,000 - 69,000	59%	32%	9%
Q1 2023 production guidance	71,000 - 74,000	61%	30%	9%
2023 annual production guidance	79,000 - 83,000	62%	29%	9%

Reserves advisories

The reserves estimates prepared herein have been evaluated by an independent qualified reserves evaluator in accordance with National Instrument 51-101 – Standards of Disclosure for Oil and Gas Activities and the Canadian Oil and Gas Evaluation Handbook ("COGE Handbook") and are effective as of December 31, 2022. All reserves information has been presented on a gross basis, which is the Company's working interest share before deduction of royalties and without including any royalty interests of the Company. The reserves have been categorized accordance with the reserves definitions as set out in the COGE Handbook. The recovery and reserve estimates contained herein are estimates only and there is no guarantee that the estimated reserves will be recovered.

Non-GAAP and other financial measures

This press release uses various specified financial measures (as such terms are defined in National Instrument 52-112 – Non-GAAP Disclosure and Other Financial Measures Disclosure ("NI 51-112")) including "non-GAAP financial measures", "non-GAAP ratios”, “capital management measures" and “supplementary financial measures” (as such terms are defined in NI 51-112), which are described in further detail below. Management believes that the presentation of these non-GAAP measures provide useful information to investors and shareholders as the measures provide increased transparency and the ability to better analyze performance against prior periods on a comparable basis.

Non-GAAP financial measures

NI 52-112 defines a non-GAAP financial measure as a financial measure that: (i) depicts the historical or expected future financial performance, financial position or cash flow of an entity; (ii) with respect to its composition, excludes an amount that is included in, or includes an amount that is excluded from, the composition of the most directly comparable financial measure disclosed in the primary financial statements of the entity; (iii) is not disclosed in the financial statements of the entity; and (iv) is not a ratio, fraction, percentage or similar representation.

These non-GAAP financial measures are not standardized financial measures under IFRS and might not be comparable to similar measures presented by other companies where similar terminology is used. Investors are cautioned that these measures should not be construed as alternatives to or more meaningful than the most directly comparable IFRS measures as indicators of NuVista's performance. Set forth below are descriptions of the non-GAAP financial measures used in this press release.

(1) Free adjusted funds flow

Free adjusted funds flow is adjusted funds flow less capital and asset retirement expenditures. Refer to disclosures under the headings "Adjusted funds flow" and "Capital expenditures" for a description of each component of free adjusted funds flow, which components are a capital management measure and a non-GAAP financial measure, respectively. Management uses free adjusted funds flow as a measure of the efficiency and liquidity of its business, measuring its funds available for capital investment to manage debt levels, pay dividends, and return capital to shareholders. By removing the impact of current period capital and asset retirement expenditures, management believes this measure provides an indication of the funds the Company has available for future capital allocation decisions.

The following tables set out our free adjusted funds flows compared to the most directly comparable GAAP measure of cash provided by operating activities less cash used in investing activities for the period:

	Three months ended December 31				Year ended December 31
($ thousands)	2022		2021		2022		2021
Cash provided by operating activities	226,688		110,063		844,816		338,578
Cash used in investing activities	(79,310	)	(42,620	)	(442,091	)	(176,258	)
Excess cash provided by operating activities over cash used in investing activities	147,378		67,443		402,725		162,320
Adjusted funds flow	256,983		151,665		892,801		320,974
Capital expenditures	(72,743	)	(86,402	)	(419,476	)	(288,846	)
Asset retirement expenditures	(1,223	)	(809	)	(9,302	)	(5,478	)
Free adjusted funds flow	183,017		64,454		464,023		26,650

(2) Capital expenditures

Capital expenditures are equal to cash used in investing activities, excluding changes in non-cash working capital, other receivable and property dispositions. Any expenditures on the other receivable are being refunded to NuVista and are therefore included under current assets. NuVista considers capital expenditures to be a useful measure of cash flow used for capital reinvestment.

The following table provides a reconciliation between the non-GAAP measure of capital expenditures to the most directly comparable GAAP measure of cash used in investing activities for the period:

	Three months endedDecember 31				Year endedDecember 31
($ thousands)	2022		2021		2022		2021
Cash used in investing activities	(79,310	)	(42,620	)	(442,091	)	(176,258	)
Changes in non-cash working capital	6,567		(44,254	)	22,615		(15,249	)
Other receivable expenditures	—		(562	)	—		(4,795	)
Property dispositions	—		1,034		—		(92,544	)
Capital expenditures	(72,743	)	(86,402	)	(419,476	)	(288,846	)

Non-GAAP ratios

NI 52-112 defines a non-GAAP ratio as a financial measure that: (i) is in the form of a ratio, fraction, percentage or similar representation; (ii) has a non-GAAP financial measure as one or more of its components; and (iii) is not disclosed in the financial statements of the entity. Set forth below is a description of the non-GAAP ratios used in this press release.

These non-GAAP ratios are not standardized financial measures under IFRS and might not be comparable to similar measures presented by other companies where similar terminology is used. Investors are cautioned that these ratios should not be construed as alternatives to or more meaningful than the most directly comparable IFRS measures as indicators of NuVista's performance.

Non-GAAP ratios presented on a "per Boe" basis may also be considered to be supplementary financial measures (as such term is defined in NI 51-112).

(1) Operating netback and corporate netback ("netbacks"), per Boe

NuVista calculated netbacks per Boe by dividing the netbacks by total production volumes sold in the period. Each of operating netback and corporate netback are non-GAAP financial measures. Operating netback is calculated as petroleum and natural gas revenues including realized financial derivative gains/losses, less royalties, transportation and operating expenses. Corporate netback is operating netback less general and administrative, deferred share units, interest and lease finance expense.

Management believes both operating and corporate netbacks are key industry benchmarks and measures of operating performance for NuVista that assists management and investors in assessing NuVista's profitability, and are commonly used by other petroleum and natural gas producers. The measurement on a Boe basis assists management and investors with evaluating NuVista's operating performance on a comparable basis.

(2) F&D costs

NuVista calculated F&D costs as the sum of development costs plus the change in future development costs ("FDC") for the period when appropriate, divided by the change in reserves within the applicable reserves category, excluding those reserves acquired or disposed.

NuVista calculated TP+PA 3-year average F&D costs as the arithmetical average of the F&D costs over the last three completed financial years.

(3) FD&A costs

NuVista calculated FD&A costs are calculated as the sum of development costs plus net acquisition costs plus the change in FDC for the period when appropriate, divided by the change in reserves within the applicable reserves category, inclusive of changes due to acquisitions and dispositions.

(4) Recycle Ratio 

NuVista calculates recycle ratio as the sum of changes in reserves (exploration and development, technical revisions, acquisitions, dispositions and economic factors) divided by annual production for the applicable period and reserve category.

Capital management measures

NI 52-112 defines a capital management measure as a financial measure that: (i) is intended to enable an individual to evaluate an entity’s objectives, policies and processes for managing the entity’s capital; (ii) is not a component of a line item disclosed in the primary financial statements of the entity; (iii) is disclosed in the notes to the financial statements of the entity; and (iv) is not disclosed in the primary financial statements of the entity.

Please refer to Note 18 "Capital Management" in NuVista's financial statements for additional disclosure net debt and adjusted funds flow, and net debt to annualized fourth quarter adjusted funds flow ratio, each of which are capital management measures used by the Company in this press release.

NuVista calculated annualized fourth quarter adjusted funds flow ratio by dividing net debt by the annualized adjusted funds flow for the fourth quarter.

Supplementary financial measures

This press release may contain certain supplementary financial measures. NI 52-112 defines a supplementary financial measure as a financial measure that: (i) is intended to be disclosed on a periodic basis to depict the historical or expected future financial performance, financial position or cash flow of an entity; (ii) is not disclosed in the financial statements of the entity; (iii) is not a non-GAAP financial measure; and (iv) is not a non-GAAP ratio.

NuVista calculates: (i) “adjusted funds flow per share” by dividing adjusted funds flow for a period by the number of weighted average common shares of NuVista for the specified period; (ii) “operating netback per share” by dividing operating netback for a period by the number of weighted average common shares of NuVista for the specified period; (iii) “corporate netback per share” by dividing operating netback for a period by the number of weighted average common shares of NuVista for the specified period; (iv) “net debt to adjusted funds flow” by dividing the net debt at the end of a period by the adjusted funds flow for such period; and (v) “net present value per share” is the net present value (discounted at 10%) in the reserve category divided by the basic common shares outstanding at the end of the period.
