Parex Resources Provides Update on Northern Llanos Operations as well as Announces Timing of Q4 2023 Results

Parex Resources Inc. (“Parex” or the “Company”) (TSX: PXT) provides an update on its Northern Llanos operations, which are being affected by ongoing social protests in the region that began on January 22, 2024. The Company also announces that it will release its Q4 2023 and FY 2023 financial and operating results, as well as its independent reserves assessment as at December 31, 2023, after markets close on Thursday, February 29, 2024.

Ongoing Social Protests that are Affecting Operations in the Northern Llanos

As reported by Colombian media outlets, the operations of energy companies that operate in the Northern Llanos region of Colombia are being impacted by ongoing social protests.

As a result of the protests, on January 22, 2024, Parex shut-in its operations at the Capachos Block(1), as well as halted drilling and testing operations at the Arauca Block(2). For the period of January 1, 2024, to February 11, 2024, estimated average Company production was approximately 53,200 boe/d(3) and current average production is roughly 50,000 boe/d(4). The Company's average production guidance for FY 2024, ranging from 54,000 to 60,000 boe/d (57,000 boe/d midpoint), remains unchanged due to production contingencies incorporated into the guidance range.

The Company has activated internal security protocols and is actively working to resume operations by engaging with stakeholders at all levels. Parex acknowledges the efforts and leadership of the Colombian national government, including various ministries and agencies, as we strive to find a mutually beneficial solution through an established engagement process.

Such statements represent Parex's internal projections, estimates or beliefs concerning, among other things, future growth, results of operations, production, future capital and other expenditures (including the amount, nature and sources of funding thereof), competitive advantages, plans for and results of drilling activity, environmental matters, business prospects and opportunities. These statements are only predictions and actual events or results may differ materially. Although the Company’s management believes that the expectations reflected in the forward-looking statements are reasonable, it cannot guarantee future results, levels of activity, performance or achievement since such expectations are inherently subject to significant business, economic, competitive, political and social uncertainties and contingencies. Many factors could cause Parex's actual results to differ materially from those expressed or implied in any forward-looking statements made by, or on behalf of, Parex.

In particular, forward-looking statements contained in this document include, but are not limited to, statements with respect to: the Company’s focus, plans, priorities and strategies; that Parex is working towards resuming operations at the Capachos and Arauca Blocks; the Company's annual average production guidance for 2024; the anticipated timing of when Parex will release its full year and fourth quarter 2023 financial and operating guidance and independent reserves assessment; and the anticipated timing of Parex's conference call to discuss its full year and fourth quarter 2023 results.

These forward-looking statements are subject to numerous risks and uncertainties, including but not limited to, the impact of general economic conditions in Canada and Colombia; prolonged volatility in commodity prices; industry conditions including changes in laws and regulations including adoption of new environmental laws and regulations, and changes in how they are interpreted and enforced in Canada and Colombia; determinations by OPEC and other countries as to production levels; competition; lack of availability of qualified personnel; the results of exploration and development drilling and related activities; obtaining required approvals of regulatory authorities in Canada and Colombia; the risks associated with negotiating with foreign governments as well as country risk associated with conducting international activities; volatility in market prices for oil; fluctuations in foreign exchange or interest rates; environmental risks; changes in income tax laws or changes in tax laws and incentive programs relating to the oil industry; changes to pipeline capacity; ability to access sufficient capital from internal and external sources; failure of counterparties to perform under contracts; the risk that Brent oil prices may be lower than anticipated; the risk that Parex's evaluation of its existing portfolio of development and exploration opportunities may not be consistent with its expectations; the risk that Parex may not resume operations at the Capachos Block or the Arauca Block when anticipated, or at all; the risk that Parex's average annual production in 2024 may be less than anticipated; the risk that Parex may not meet its production guidance for the year ended December 31, 2024; the risk that production growth does not occur as forecasted; the risk that Parex may not release its full year and fourth quarter 2023 financial and operating guidance and independent reserves assessment when anticipated, or at all; the risk that Parex may not hold a conference call to discuss its full year and fourth quarter 2023 results when anticipated, or at all; and other factors, many of which are beyond the control of the Company. Readers are cautioned that the foregoing list of factors is not exhaustive.

Oil & Gas Matters Advisory

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 Mcf: 1Bbl, utilizing a conversion ratio at 6 Mcf: 1 Bbl may be misleading as an indication of value.

References to conventional natural gas, heavy crude oil and light and medium crude oil in this press release refer to conventional natural gas, heavy crude oil and light and medium crude oil product types, respectively, as defined in National Instrument 51-101 – Standards of Disclosure for Oil and Gas Activities.
