Arfan Khan, Chief Executive Officer of Nostrum Oil & Gas, commented:

"2023 has been a transformative year for Nostrum, as it commenced execution of its mixed-asset energy strategy by implementing key catalyst projects.

We successfully completed the restructuring of our bonds, leading to a strengthened balance sheet and helping to safeguard our cash reserves. This financial stability enabled us to expand our upstream portfolio, notably through the acquisition of the Stepnoy Leopard fields and commencement of a limited-scale drilling program at the Chinarevskoye field. In our midstream business, we achieved a major milestone by starting to process third-party feedstock from Ural Oil & Gas ("Ural O&G") in our gas treatment facility.

The financial performance of the Group in 2023 was helped by the improved production performance from the gas-lift expansion and improved netbacks under new off-take agreements. However, revenues decreased year-on-year by 40% due to the continued high production declines of the mature Chinarevskoye field, in combination with lower average Brent prices of $82/bbl compared with $101/bbl for 2022. Consequently, our EBITDA was reduced to US$42 million, with an EBITDA margin of 35.2%, reflecting the impact of reduced revenues against a largely fixed operating cost base.

In 2023, we further strengthened our ESG task force. As evaluated by Sustainalytics, our ESG Risk Rating improved to 30.1 from 40.1 in 2022, transitioning Nostrum to within 0.1 point of the "Medium Risk" categoryand ranking Nostrum among the top 10% best ESG performing companies in the Oil & Gas Exploration and Production sector according to Sustainalytics ranking.

As we transition into 2024, I am enthusiastic about the future and the forthcoming commercial opportunities. Nostrum is poised to advance its strategic objectives, contributing to regional development, supporting Kazakhstan's energy transition, and enhancing value for our investors and stakeholders."

2023 Highlights

Financial

· Revenues of US$119.6m with average 2023 Brent prices of US$82/bbl (FY2022: revenues of US$199.7m, average Brent price of US$101/bbl). From 2023, the Company negated the adverse impact of Urals-Brent spread on oil and gas condensate exports, by using alternative delivery routes and destinations which resulted in improved netbacks in 2023 vs 2022.

· EBITDA1 of US$42.1m (2022: US$115.7m) and EBITDA1 margin of 35.2% (FY2022: 57.9%).

US$25.2m remained as restricted cash at 31 December 2023 (31 December 2022: US$31.0m), including US$16.5m held in a debt service retention account under the terms of the bond trust deeds (31 December 2022: US$22.8m in escrow account under the forbearance agreement).

· The Group continued focusing on cost optimisation to help manage liquidity, with increases necessary to support the growth projects such as Ural O&G processing and Stepnoy Leopard appraisal and project development.

· Daily sales volumes averaged 8,874 boepd (2022: 12,524 boepd).

· Two-well drilling programme commenced to keep the balance between investment in risk-based opportunities and maintaining our license commitments for the Chinarevskoye field.

· Successfully launched the expansion of Gas lift system, almost doubling thew total field gas lift capacity and helped to slow down the production decline from the Chinarevskoye field.

· Total Proven plus Probable ("2P") reserves of 23.2 million barrels of oil equivalent ("mmboe") and together with 8.2 mmboe of Possible reserves a total "3P" reserves of 31.4 mmboe, based on the management's estimates updated from the annual reserves audit conducted by Ryder Scott as of 31 December 2022.

Ural Oil & Gas Processing

The tie-back project commenced with 300 th.m3 of raw gas per day from U-21 well in December 2023 and continues to ramp-up. Ural O&G plan to connect an additional four wells during H2 2024 with an estimated 1.5mn m3 of raw gas per day from these four wells.

This collaboration with Ural O&G represents a pivotal moment for us as we expand the utilisation of our world-class treatment facilities and position ourselves as a preferred partner for handling and processing third-party gas in Western Kazakhstan. Our state-of-the-art infrastructure is designed to process up to 4.2 bcm per annum or more of third-party gas, offering faster processing solutions at significantly reduced costs compared to other alternatives. The realisation of the Ural O&G tie-back project is a proof-of- concept for commercialisation of the stranded gas-fields in West Kazakhstan that would otherwise not be economic as stand-alone developments.

GTU-3 Gas Plant Re-start

The Company successfully re-started its c.$750 million state-of-the-art GTU-3 gas plant, with an additional 2.5 billion cubic metres per annum gas processing capacity and resulting in improved efficiency in the extraction of LPG by 15%-20%.
