Parex Resources Announces 12 Consecutive Years of Reserves Per Share Growth, a 50% Increase to the Regular Dividend and Provides 2023 Guidance Update

Parex Resources Inc. ("Parex" or the "Company") (TSX: PXT) is pleased to announce the results of its annual independent reserves assessment as at December 31, 2022, as well as a corporate update. The financial and operational information contained below is based on the Company's unaudited estimated results for year-end December 31, 2022. All currency amounts are in United States dollars unless otherwise stated. The following reserves categories are discussed in this news release: proved developed producing ("PDP"); proved ("1P"); proved plus probable ("2P"); and proved plus probable plus possible ("3P").

Key Highlights

• Twelve consecutive years of PDP, 1P and 2P reserves per share growth (on a boe basis), with double digit percentage increases from 2021.
• Achieved a strong 1P reserve replacement ratio of 128%.
• Strategically deployed $100 million of working capital to complete a voluntary, internal corporate entity restructuring that increases 2023 funds flow and free funds flow guidance by $65 million (midpoint) as well as provides the Company with an increased outlook through 2027.
• Declared a Q1 2023 regular dividend of C$0.375 per share or C$1.50 per share annualized, representing a 50% increase from the Company's Q4 2022 regular dividend; Parex first initiated a regular dividend at C$0.125 per share quarterly in 2021.
• Repurchased approximately 1 million shares year-to-date 2023 under the current normal course issuer bid.
• Recognized for leadership in ESG, where Parex was one of three Canadian-listed exploration and production companies included in the 2023 Bloomberg Gender-Equality Index.

Imad Mohsen, President and Chief Executive Officer, commented: "Parex achieved strong reserve replacement ratios in 2022 from the implementation of new technology and focused investments that are resulting in an outlook for reduced maintenance capital and further optimized production from key assets. The results that we are seeing today, in addition to our positive outlook for the business, gives us the confidence to sustainably increase our regular dividend to shareholders. With investments across our world-class Colombian asset base, the portfolio is well positioned to deliver a step-change in capital efficiency and continue being the foundation for increased shareholder returns."

2022 Year-End Corporate Reserves Report: Highlights

For year-ended December 31, 2022, Parex:

• Grew reserves per share (on a boe basis) across PDP, 1P and 2P for the 12 ^th consecutive year:
  • PDP: 13% increase from 2021;
  • 1P: 15% increase from 2021;
  • 2P: 12% increase from 2021.
• More than replaced total 2022 production (approximately 19.0 million barrels of oil equivalent ("MMboe")) with reserve replacement ratios of:
  • PDP: 112%, with reserve additions of 21.2 MMboe;
  • 1P: 128%, with reserve additions of 24.4 MMboe;
  • 2P: 110%, with reserve additions of 20.9 MMboe.
• Realized estimated finding, development & acquisition ("FD&A") costs (using estimated 2022 adjusted funds flow from operations of $42.43 per boe ^{( 1)} ) of:
  • PDP: $25.35 per boe resulting in a 1.7x recycle ratio ^{( 1)} ;
  • 1P: $25.92 per boe resulting in a 1.6x recycle ratio ^{( 1)} ;
  • 2P: $28.39 per boe resulting 1.5x recycle ratio ^{( 1)} .
• Realized growth in its after-tax net asset value ("NAV") per share (discounted at 10% and using the GLJ Brent forecast) even after incorporating the estimated impact of the recent Colombia government tax reform:
  • PDP: C$23.83 (6% increase from 2021) ^{( 1)} ;
  • 1P: C$31.63 (9% increase from 2021) ^{( 1)} ;
  • 2P: C$43.45 (13% increase from 2021) ^{( 1)} .
• After accounting for the 2022 drilling campaign, expanded corporate gross 2P future locations to 147 from 108 last year, demonstrating significant running room.
• Added 1P and 2P reserves at the Cabrestero Block (100% W.I.) of 8.9 and 8.8 MMboe, respectively.
• Increased its Q4 2022 average production by approximately 9% over the comparative quarter in 2021 and maintained a 2P reserve life index of over 10 years.

Production Update

2022 Review

(1) Production volumes for the three months ended December 31, 2022, and for the year-ended December 31, 2022, are estimated.

• Q4 2022 average production is estimated to be 54,257 boe/d, up 9% from Q4 2021.
• FY 2022 average production is estimated to be 52,049 boe/d, an increase of 11% from FY 2021.

2023 Outlook

• In the Northern Llanos, on January 21, 2023, the Company proactively shut-in its Capachos Block (50% W.I.) and halted drilling operations at the Arauca Block (50% W.I.), due to heightened security concerns related to peace talks at the Federal Government level in Colombia.
  • As a result of this shut-in, net production is being impacted by approximately 6,000 boe/d and is affecting the pace that new wells can be drilled and brought online.
  • The Company is actively engaging with national and regional stakeholders and is optimistic that it will be able to resume full operations in the Northern Llanos in Q1 2023; however, the Company's top priority is the safety of our employees and contractors.
• Parex's average production guidance of 57,000 to 63,000 boe/d for FY 2023 had been widened relative to previous years in order to better account for above ground factors that can at times impact Colombian operations.
  • Due to the Northern Llanos shut-in, for Q1 2023 Parex expects its production to be below its 2023 annual average production guidance range, subject to the length of the shut-in and halted drilling operations; however, Parex expects to be within its 2023 annual average production guidance range in Q2 2023 and for the full year 2023.
  • Prior to the heightened security concerns, Parex was making steady progress at the Arauca Block (50% W.I.), where civil work activities were ongoing in 2022 and the first well of a material, multi-year drilling campaign was successfully spud in early January 2023.

Voluntary Restructuring Increases 2023 Funds Flow and Free Funds Flow Guidance as well as Outlook Through 2027

Parex has completed a voluntary, internal corporate entity restructuring to consolidate certain assets in the Southern Llanos into one corporate entity for operational and administrative optimization.

The financial impact of this restructuring is that the Company will incur Colombia capital gains taxes in Q4 2022, while gaining an expected increase of $325 million to the Company's deferred tax asset balance as at year-end December 31, 2022, which is anticipated to provide benefits over the 2023-2027 fiscal year period. The restructuring has an estimated cost, in the form of an increased current tax expense for Q4 2022, of $100 million. The Company's Q4 2022 current tax expense is now expected to be roughly $175 million, compared to the Company's original internal forecast of approximately $75 million; full-year 2022 net income will increase by approximately $225 million due to a deferred tax recovery, offset by the incremental Q4 2022 current tax expense of $100 million.

As a result of the restructuring, the Company expects a lower effective tax rate over the 2023-2027 fiscal year period. At the previously budgeted $80 per barrel Brent oil price assumption and existing Colombian tax regulations, the expected benefits of the lower effective tax rate in 2023, which are higher funds flow provided by operations and free funds flow, are reflected in the updated 2023 guidance below.

Return of Capital Update

50% Increase to the Q1 2023 Dividend

Parex's Board of Directors has approved a Q1 2023 regular dividend of C$0.375 per share to be paid on March 31, 2023, to shareholders of record on March 15, 2023, representing a 50% increase from the Company's Q4 2022 regular dividend of C$0.25 per share. The Company first initiated a regular dividend at C$0.125 per share quarterly in 2021.

This quarterly dividend payment to shareholders is designated as an "eligible dividend" for purposes of the Income Tax Act (Canada).

Commenced 2023 Share Buybacks under Current Normal Course Issuer Bid

As at January 31, 2023, Parex has repurchased approximately 1 million shares under its normal course issuer bid ("NCIB") at an average price of C$21.70 per share, for total consideration of roughly C$21.7 million. Over and above the increased regular dividend, the Company intends on continuing to utilize its current NCIB in line with Parex's commitment to return 100% of free funds flow to its shareholders.

Parex Resources Included in the 2023 Bloomberg Gender-Equality Index

Parex has joined 483 other companies as a member of the 2023 Bloomberg Gender-Equality Index (GEI), a modified market capitalization-weighted index developed to gauge the performance of public companies dedicated to reporting gender-related data. The Company submitted a social survey created by Bloomberg, in collaboration with subject matter experts globally. Those included on this year's index scored at or above a global threshold established by Bloomberg to reflect disclosure and the achievement or adoption of best-in-class statistics and policies.

Reserves Advisory

The recovery and reserve estimates of crude oil reserves provided in this news release are estimates only, and there is no guarantee that the estimated reserves will be recovered. Actual crude oil reserves may eventually prove to be greater than, or less than, the estimates provided herein. All December 31, 2022 reserves presented are based on GLJ's forecast pricing effective January 1, 2023. All December 31, 2021 reserves presented are based on GLJ's forecast pricing effective January 1, 2022. All December 31, 2020 reserves presented are based on GLJ's forecast pricing effective January 1, 2021.

It should not be assumed that the estimates of future net revenues presented herein represent the fair market value of the reserves. There are numerous uncertainties inherent in estimating quantities of crude oil, reserves and the future cash flows attributed to such reserves.

"Proved Developed Producing Reserves" are those reserves that are expected to be recovered from completion intervals open at the time of the estimate. These reserves may be currently producing or, if shut-in, they must have previously been on production, and the date of resumption of production must be known with reasonable certainty.

"Proved Developed Non-Producing Reserves" are those reserves that either have not been on production or have previously been on production but are shut-in and the date of resumption of production is unknown.

"Proved Undeveloped Reserves" are those reserves expected to be recovered from known accumulations where a significant expenditure (e.g. when compared to the cost of drilling a well) is required to render them capable of production. They must fully meet the requirements of the reserves category (proved, probable, possible) to which they are assigned.

"Proved" reserves are those reserves that can be estimated with a high degree of certainty to be recoverable. It is likely that the actual remaining quantities recovered will exceed the estimated proved reserves.

"Probable" reserves are those additional reserves that are less certain to be recovered than proved reserves. It is equally likely that the actual remaining quantities recovered will be greater or less than the sum of the estimated proved plus probable reserves.

"Possible" reserves are those additional reserves that are less certain to be recovered than probable reserves. There is a 10 percent probability that the quantities actually recovered will equal or exceed the sum of proved plus probable plus possible reserves. It is unlikely that the actual remaining quantities recovered will exceed the sum of the estimated proved plus probable plus possible reserves.

The term "Boe" means a barrel of oil equivalent on the basis of 6 Mcf of natural gas to 1 barrel of oil ("bbl"). Boe's may be misleading, particularly if used in isolation. A boe conversation 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. Given 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 ratio at 6:1 may be misleading as an indication of value.

Light crude oil is crude oil with a relative density greater than 31.1 degrees API gravity, medium crude oil is crude oil with a relative density greater than 22.3 degrees API gravity and less than or equal to 31.1 degrees API gravity, and heavy crude oil is crude oil with a relative density greater than 10 degrees API gravity and less than or equal to 22.3 degrees API gravity.

With respect to F&D costs, the aggregate of the exploration and development costs incurred in the most recent financial year and the change during that year in estimated future development costs generally will not reflect total F&D costs related to reserve additions for that year.

The estimates of reserves and future net revenue for individual properties may not reflect the same confidence level as estimates of reserves and future net revenue for all properties, due to the effects of aggregation.

This press release contains several oil and gas metrics, including reserve replacement, reserve additions including acquisitions, and RLI. In addition, the following non-GAAP financial measures and non-GAAP ratios, as described below under "Non-GAAP and Other Financial Measures", can be considered to be oil and gas metrics: F&D costs, FD&A costs, F&D recycle ratio, FD&A recycle ratio, funds flow provided by operations, funds flow from operations netback, reserve replacement and NAV. Such oil and gas metrics have been prepared by management and do not have standardized meanings or standard methods of calculation and therefore such measures may not be comparable to similar measures used by other companies and should not be used to make comparisons. Such metrics have been included herein to provide readers with additional measures to evaluate the Company's performance; however, such measures are not reliable indicators of the future performance of the Company and future performance may not compare to the performance in previous periods and therefore such metric should not be unduly relied upon. Management uses these oil and gas metrics for its own performance measurements and to provide security holders with measures to compare the Company's operations over time. Readers are cautioned that the information provided by these metrics, or that can be derived from the metrics presented in this news release, should not be relied upon for investment or other purposes. A summary of the calculations of reserve replacement and RLI are as follows, with the other oil and gas metrics referred to above being described herein under "Non-GAAP and Other Financial Measures":

• Reserve replacement is calculated by dividing the annual reserve additions by the annual production.
  
  
• Reserve additions including acquisitions is calculated by the change in reserves category and adding current year annual production.
  
  
• RLI is calculated by dividing the applicable reserves category by the annualized fourth quarter production.
  

The following abbreviations used in this press release have the meanings set forth below:

Unaudited Financial Information

Certain financial and operating results included in this news release, including capital expenditures, production information, funds flow provided by operations, operating costs and the deferred tax asset balance are based on unaudited estimated results. These estimated results are subject to change upon completion of the Company's audited financial statements for the year ended December 31, 2022, and any changes could be material. Parex anticipates filing its audited financial statements and related management's discussion and analysis for the year ended December 31, 2022 on SEDAR on or before March 31, 2023.

Non-GAAP and Other Financial Measures Advisory

This press release uses various "non-GAAP financial measures", "non-GAAP ratios", "financial measures" and "capital management measures" (as such terms are defined in NI 52-112), which are described in further detail below. Such measures are not standardized financial measures under IFRS and might not be comparable to similar financial measures disclosed by other issuers. Investors are cautioned that non-GAAP financial measures should not be construed as alternatives to or more meaningful than the most directly comparable GAAP measures as indicators of Parex' performance.

These measures facilitate management's comparisons to the Company's historical operating results in assessing its results and strategic and operational decision-making and may be used by financial analysts and others in the oil and natural gas industry to evaluate the Company's performance. Further, management believes that such financial measures are useful supplemental information to analyze operating performance and provide an indication of the results generated by the Company's principal business activities.

Please refer to the Company's Management's Discussion and Analysis of the financial condition and results of operations for the period ended September 30, 2022 dated November 3, 2022 (the "MD&A"), which is available at the Company's website at www.parexresources.com and on the Company's profile on SEDAR at www.sedar.com for additional information about such financial measures, including reconciliations to the nearest GAAP measures, as applicable.

Set forth below is a description of the non-GAAP financial measures, non-GAAP ratios, supplementary financial measures and capital management measures used in this press release.

Non-GAAP Financial Measures

Capital expenditures, is a non-GAAP financial measure which the Company uses to describe its capital costs associated with oil and gas expenditures. The measure considers both property, plant and equipment expenditures and exploration and evaluation asset expenditures which are items in the Company's statement of cash flows for the period. In Q3 2022, the Company changed how it presents exploration and evaluation expenditures. Amounts have been restated for prior periods to conform to the current year's presentation, refer to note 2 of the Company's consolidated interim financial statements for the period ended September 30, 2022.

Free funds flow, is a non-GAAP financial measure that is determined by funds flow provided by operations less capital expenditures. In Q3 2022, the Company changed how it presents exploration and evaluation expenditures included in total capital expenditures. Amounts have been restated for prior periods to conform to the current year's presentation, refer to note 2 of the Company's consolidated interim financial statements for the period ended September 30, 2022. The Company considers free funds flow or free cash flow to be a key measure as it demonstrates Parex' ability to fund return of capital, such as the NCIB or dividends, without accessing outside funds and is calculated as follows:

Non-GAAP Financial Ratios

Funds flow provided by operations per boe or funds flow netback per boe , is a non-GAAP ratio that includes all cash generated from operating activities and is calculated before changes in non-cash working capital, divided by produced oil and natural gas sales volumes. The Company considers funds flow netback to be a key measure as it demonstrates Parex' profitability after all cash costs relative to current commodity prices.

Finding & development Costs (F&D costs) and finding, development and acquisition Costs (FD&A costs), is a non-GAAP ratio that helps to explain the cost of finding and developing additional oil and gas reserves. F&D costs are determined by dividing capital expenditures plus the change in FDC in the period divided by BOE reserve additions in the period. FD&A costs are determined by dividing capital expenditures in the period plus the change in FDC plus acquisition costs divided by BOE reserve additions in the period.

(1) All reserves are presented as Parex working interest before royalties. Please refer to the "Reserves Advisory" section for a description of each reserve category.
(2) Calculated using unaudited estimated capital expenditures for the period ended December 31, 2022.

Recycle ratio, is a non-GAAP ratio that measures the profit per barrel of oil to the cost of finding and developing that barrel of oil. The recycle ratio is determined by dividing the annual funds flow provided by operations per boe by the F&D costs and FD&A costs in the period.

(1) Recycle ratio is calculated as funds flow provided by operations per boe divided by F&D or FD&A as applicable. Three-year funds flow provided by operations on a per boe basis is calculated using weighted average sales volumes.
(2) Adjusted estimated 2022 funds flow per boe reflects the one-time $100 million tax transaction cost related to the voluntary, internal corporate entity restructuring.

Net Asset Value per share, is a non-GAAP ratio that combines the 51-101 NPV10 value after tax with the Company's estimated working capital at the period end date divided by common shares outstanding at the period end date. The Company uses the Net Asset Value per share as a way to reflect the Company's value considering both existing working capital on hand plus the NPV10 after tax value on Oil and Gas Reserves. NAV per share is stated in CAD dollars using an exchange rate of USDCAD= 1.3544 . Net asset value is defined as total assets less total liabilities.

Capital Management Measures

Funds flow provided by operations, is a capital management measure that includes all cash generated from operating activities and is calculated before changes in non-cash working capital.
