**FOR IMMEDIATE DISTRIBUTION** 

**GEOPARK COMMENTS ON ENGAGEMENT WITH PAREX RESOURCES<br>** 

<br> **GEOPARK ENGAGED SUBSTANTIVELY AND PROVIDED AMPLE INCREMENTAL INFORMATION TO PAREX TO SUPPORT AN IMPROVED OFFER ABOVE $9.00 PER SHARE<br>GEOPARK REMAINS CONFIDENT IN ITS STRATEGY AND FUTURE GROWTH PROSPECTS<br>** 

<br> Bogota, Colombia – December 9, 2025 - GeoPark Limited ("GeoPark" or the "Company") (NYSE: GPRK), a leading independent energy company with over 20 years of successful operations across Latin America, today commented on Parex Resources Inc.'s ("Parex") announcement that it has halted discussions with GeoPark regarding a potential transaction:

&nbsp;&nbsp;&nbsp;&nbsp;· GeoPark's Board and management team have
always been open to entering into transactions that maximize value for our shareholders. As such, we entered into discussions with Parex
in good faith, aiming to negotiate a mutually agreeable transaction. From the outset of negotiations, we have communicated our belief
that Parex's September 4, 2025, offer of $9.00 per share undervalues GeoPark.

&nbsp;&nbsp;&nbsp;&nbsp;· Over six weeks of extensive Special Committee
and Board sessions and numerous meetings between our respective senior management teams, we provided Parex and its advisors access to
substantial and comprehensive, non-public technical and financial information relevant to our ongoing operations and future upside potential
– all of which is clearly incremental to the facts upon which Parex's original offer was founded. Importantly, Parex's
$9.00 per share offer ascribed no value to GeoPark's transformative Vaca Muerta acquisition which was announced on September 25,
2025. The Board has communicated that any credible or constructive engagement going forward would require a revised proposal beginning
in the double-digits.

This incremental information includes:

&nbsp;&nbsp;&nbsp;&nbsp;· Certified 2025 reserves report showing total 2P reserves increased 38% year-over-year
to 121 mmboe (including an increase in Colombia as well as the addition of the Argentinian asset), with reserve replacement ratios for
1P, 2P and 3P all exceeding 100% – underscoring GeoPark's ability to fully replace production and continue building long-term
asset value.

This represents a 48% increase in 2P reserves versus the 82 mmboe available at the time of Parex's original offer (2024 2P reserves of 87.6 mmboe, net of previously announced 2025 divestments)

&nbsp;&nbsp;&nbsp;&nbsp;· Data supporting an additional ~18 mmboe of risked reserves across the Llanos
34 and Llanos 123 blocks in Colombia (pending certification), further enhancing GeoPark's near-term production and value outlook.

&nbsp;&nbsp;&nbsp;&nbsp;· A reserves report certifying a 22% increase (206 million barrels) in 2P OOIP
in the Llanos 34 block, confirming a larger resource base and strengthening the asset's long-term upside.

&nbsp;&nbsp;&nbsp;&nbsp;· Detailed information demonstrating that the Vaca Muerta transaction materially
strengthens GeoPark's asset base and growth trajectory, adding ~37 mmboe of 2P reserves, extending the Company's 2P reserve
life index to 12.7 years.

In an effort to ensure that GeoPark shareholders also had the latest information, the Company released its <u>2025 Reserves Report</u> and <u>2026-2028 Guidance</u> publicly.

**Background and Engagement with Parex**

As announced on October 29, 2025, the GeoPark Board unanimously rejected an unsolicited, non-binding proposal from Parex to acquire GeoPark in an all-cash transaction for $9.00 per share, received on September 4, 2025. Parex's initial offer was submitted mere weeks before GeoPark's transformative transaction in Vaca Muerta, which materially enhanced GeoPark's asset base and growth trajectory. After engaging in a comprehensive evaluation process, the Board concluded the proposal undervalued the Company and was not in the best interests of GeoPark or its shareholders. GeoPark's discussions with its shareholders have supported this view.

Following the completion of GeoPark's transformative transaction in Vaca Muerta and the public reiteration of Parex's $9.00 per share offer, GeoPark's Board formed a Special Committee of independent directors to evaluate any potential revised offer from Parex and other value-maximizing alternatives for the Company. In addition, the GeoPark Board authorized the Company to move expeditiously to execute a non-disclosure agreement and establish a virtual data room (VDR) through which it provided Parex with access to extensive technical and financial information relevant to GeoPark's operations and growth prospects, which was clearly incremental to the facts upon which Parex's September 4 offer was founded.

Through the course of GeoPark's engagement with Parex, Parex communicated that it is only interested in GeoPark's Colombian assets given its limited familiarity with unconventional resource development, including in Argentina, and its reservations more broadly regarding operating in Argentina based on past experience. GeoPark believes these factors constrain Parex's ability to reflect the full value of the Company's diversified portfolio in any revised proposal.

GeoPark subsequently was disappointed to learn from Parex's CEO on December 1, 2025 that Parex did not intend to increase its offer to acquire GeoPark for more than $9.00 per share. The GeoPark Board, consistent with its desire to maximize value for shareholders and seriously explore all options to do so, opened a direct line of communication with the Parex Board.

The GeoPark Board urged the Parex Board to reconsider its original offer and re-engage in negotiations with a view to reaching an outcome that is in the best interests of both companies' shareholders.

**<br> Outlook**

GeoParks expects Adjusted EBITDA to more than double by 2028, driving a larger enterprise value supported by increased cash flow, lower leverage, and a broader, more diversified asset base. GeoPark will continue to focus on its operational strengths, financial discipline, and portfolio of high-quality assets, including executing its two-pronged strategy in Colombia and Argentina:

&nbsp;&nbsp;&nbsp;&nbsp;· **Maximizing Core Production and Cash Generation in Colombia**: The Company is focused on sustaining and improving the performance of its flagship Llanos 34 block and other key operated
and non-operated assets. Following a strong 2025 and positive developments since GeoPark's 2025 Investor Day, Colombian production
has reached a positive inflection point earlier than expected. Production is set to grow, supported by disciplined development, base optimization,
enhanced recovery techniques, and strong results from recent wells. Colombia will continue to provide a solid foundation to generate sustainable
free cash flow, balance sheet strength, and shareholder returns.

&nbsp;&nbsp;&nbsp;&nbsp;· **Returning to Growth with Vaca Muerta, Argentina**:
With the successful integration of the Loma Jarillosa Este and Puesto Silva Oeste blocks, GeoPark is confident it can unlock material
long-term growth from its position in the unconventional Neuquén Basin. The team is focusing on accelerating drilling activity
to deliver a step-change in production and cash flow. Vaca Muerta is expected to become a core growth platform in GeoPark's portfolio
by year-end 2028.

GeoPark remains open to considering offers that appropriately value the Company.
