NG ENERGY ANNOUNCES ARUCHARA-6 WELL RESULTS AT MARIA CONCHITA AND SPUDDING OF ENCANTADO-1X AT SINU-9

NG Energy International Corp. has released the initial results from the Aruchara-6 well at the company's Maria Conchita block in Colombia, and has provided an operational update on the Sinu-9 block. The company's contractual interest in both the Maria Conchita block and the Sinu-9 block is held through its indirect wholly owned subsidiary, Operadora NG Energy International S.A. (Operadora NGE), which operates in Colombia through its registered branch.

• Aruchara-6 successfully drilled, completed and tied into the CPF at Maria Conchita, and is now producing.
• The well has produced at rates of up to 8.7 MMcf/d (million cubic feet per day) gross (6.96 MMcf/d net) during initial flow tests done through the CPF, with a choke of 30/64 and average tubing head pressure of 780 psi (pounds per square inch).
• Total field production at Maria Conchita with the addition of this well is expected to increase to 23.0 MMcf/d gross (18.4 MMcf/d net), against installed processing capacity of 30.0 MMcf/d.
• Incremental volumes above the company's 15.0 MMcf/d gross contracted offtake at Maria Conchita are being sold into the Colombian spot market at average prices of approximately $14.00 (U.S.) to $16.00 (U.S.)/Mcf, with some volumes realizing in excess of $20.00 (U.S.)/Mcf.
• Combined company net production across Maria Conchita and Sinu-9 is expected to increase to 29.1 MMcf/d.
• Additional upgrades under way at the CPF, including an additional compressor and improvements to the heat exchangers, cooling and dehydration facilities, to increase plant reliability as the facility operates at or near capacity.
• At Sinu-9, the Encantado-1X well was spudded on Oct. 6, 2026, and drilling is currently under way.
• commissioning of the Sinu-9 pipeline loop is now complete, increasing gross transportation capacity to 40 to 45 MMcf/d (15.6 to 17.6 MMcf/d net).
• Following Encantado-1X, the Sinu-9 consortium (as defined herein) expects at least one additional well to be drilled at Sinu-9 in 2026.

Maria Conchita block -- Aruchara-6 well results

The Aruchara-6 well has been successfully drilled to a total depth of 9,352 feet, hitting the H1 target as designed and passing through the H2, H3, H4, H5 and H6 zones, with all zones showing positive results of gas at surface and through wireline logs. The well has been completed and connected to the central processing facility (CPF), with well performance evaluation now under way through the CPF and new gas volumes being sold into the Colombian marketplace.

During initial flow testing through the CPF, Aruchara-6 produced at rates of up to 8.7 MMcf/d gross (6.96 MMcf/d net), on a 30/64 choke at an average tubing head pressure of 780 psi. The well is now on production, with gas volumes being sold into the Colombian marketplace.

With Aruchara-6 on production, total field production at Maria Conchita is expected to increase to 23.0 MMcf/d gross (18.4 MMcf/d net), compared with 16.0 MMcf/d gross (12.8 MMcf/d net) prior to the addition of the well. This is expected to bring the combined company net production across Maria Conchita and Sinu-9 to approximately 29.1 MMcf/d. Net production volumes for Maria Conchita reflect the company's 80-per-cent working interest under private agreements, rather than the contractual interest registered with Agencia Nacional de Hidrocarburos (the ANH).

Gas volumes in excess of those sold under the company's existing contracted offtake agreements are being sold into the Colombian marketplace at average prices of approximately $14.00 (U.S.) to $16.00 (U.S.)/Mcf, with some volumes exceeding $20.00 (U.S.)/Mcf, reflecting the premium Colombian natural gas pricing environment. The company's contracted offtake agreements at Maria Conchita cover volumes up to 15.0 MMcf/d gross, with all incremental volumes above this threshold sold at spot prices.

Maria Conchita block -- CPF upgrades

As total field production at Maria Conchita approaches the CPF's 30 MMcf/d processing capacity, the company's infrastructure partner, GTX International Corp., is advancing a series of upgrades designed to increase the reliability of the CPF as it operates at or near capacity. Prior to the end of October, an additional compressor will be installed to accommodate upcoming production volumes with a greater level of reliability. GTX is also in the process of implementing improvements to the heat exchangers and the cooling facility, with further upgrades to the dehydration facility expected to be completed by the end of October, 2026.

Together, these investments are intended to ensure the CPF operates reliably as the facility approaches full capacity, supporting sustained production growth from the Aruchara well series while enhancing uptime and operating efficiency across the Maria Conchita block.

Sinu-9 block -- operational update

At the Sinu-9 block, Maurel & Prom Colombia Sociedad Ltd., as operator of the consortium formed with the company through Operadora NGE, spudded the Encantado-1X well on Oct. 6, 2026. Encantado-1X is the next well in the Sinu-9 consortium's 2026 drilling program, and drilling is currently under way. The Sinu-9 consortium expects that, following completion of Encantado-1X, at least one additional well will be drilled at Sinu-9 this year.

The company views Encantado-1X as an important well for the continued delineation of the Sinu-9 block for several reasons. The well is expected to help define the southern limits of the reservoir and provide depth calibration across the block. The area is anticipated to be of higher pressure than previously drilled locations, which management expects to have a positive impact on production rates. Encantado-1X is also expected to confirm the presence of natural gas in the pre-CDO formation and verify the potential for liquids within the reservoir.

In support of the Sinu-9 consortium's drilling program, commissioning of the first loop of the pipeline from the Jobo connection point, constructed by the company's infrastructure partner Infraes SAS ESP, is now complete. Gross transportation capacity at the Sinu-9 block has increased from 30.0 MMcf/d to between 40.0 and 45.0 MMcf/d, representing net entitlement to the company of between 15.6 and 17.6 MMcf/d.

Jorge Fonseca, chief executive officer of NGE, commented: "Aruchara-6 has delivered positive gas results and is now tied into our main processing facility and producing, having flowed at up to 8.7 MMcf/d during well testing. The addition of the well is expected to bring total field production at Maria Conchita up to 23.0 MMcf/d. With the block now approaching the capacity of our processing facility, the upgrades GTX is completing over the coming weeks will ensure the CPF runs reliably at these higher throughput levels. At Sinu-9, Maurel & Prom Colombia Sociedad Ltd., as operator of the Sinu-9 consortium, spudded Encantado-1X on Oct. 6 and drilling is now under way -- a well we believe is important for defining the southern limits of the reservoir, testing a higher-pressure area of the block and confirming the presence of gas in the pre-CDO formation. With at least one further well planned by the Sinu-9 consortium before year-end, we are finishing 2026 with real momentum across both of our assets."
