H1 2023 Highlights:

Financial

• Revenues of US$52.8m (H1 2022: US$107.8m) against average realised Brent oil price of US$79.9/bbl (H1 2022: US$104.7/bbl). Decrease in revenues compared to H1 2022 resulted from declining production and relatively lower average product prices.

• EBITDA¹ of US$15.5m (H1 2022: US$68.8m) with EBITDA¹ margin of 29.4% (H1 2022: 63.8%).

• The Group’s unrestricted cash position as at 30 June 2023 was US$192m (31 March 2023: US$191m). Restricted cash balance was US$16.3m as at 30 June 2023 (31 March 2023: US$22.6m), which decreased due to US$6.2m interests payments for the period from 9 February 2023 to 29 June 2023, and was replenished subsequently to cover the next two interest payments. The next semi-annual cash interest payment is scheduled for December 2023.

• Pursuant to the terms of the Restructuring, the interest accrued on the SSNs and the SUNs from 1 January 2022. Accordingly, cash interest accrued to 9 February 2023 in the amount of US$17.5 million was paid in cash to the Noteholders upon the issuance of the SSNs and the SUNs.

• The Group continues to focus on cost optimisation to help manage liquidity.

Operational

• Daily production after treatment averaged 10,048 boepd (H1 2022: 14,167 boepd).

• Daily sales volumes averaged 9,020 boepd (H1 2022: 13,102 boepd).

• Following the end of the reporting period, the Group completed the acquisition of an 80% interest in Positiv Invest LLP, which holds the subsoil use right for the Stepnoy Leopard fields. Management estimates that the Stepnoy Leopard fields hold between 50 mmboe and 150 mmboe of recoverable volumes which are considered contingent resources, with over 20% estimated to be liquids. The Company launched an appraisal programme with the intention of preparing a technical expert’s report which could allow re-classification of certain of the hydrocarbon resources into reserves.

• Following the end of the reporting period, the Group successfully launched the expansion of its Gas lift system with the new compressor doubling its capacity and helping to slow down production decline from its maturing Chinarevkoye field. The initial production gains exceed management’s expectations and further updates on production guidance will be provided as part of the Q3 2023 operational update.

• The GTU-3 restart is progressing according to the plan with wet gas introduction expected during H2 2023, following which all gas is planned to be processed through the 3^rd train of the gas treatment unit to assess its efficiency.

• The Group continues its well and reservoir management strategy through well workovers and rigless well intervention in 2023.

• Following the end of the reporting period, the Board of Directors approved a limited-scale drilling programme for the Chinarevskoye field to be executed over 2023-2024, which is in line with the commitments of the Company’s subsidiary Zhaikmunai LLP under its production sharing agreement. The programme will leverage existing wellbores to reduce costs and carries a level of uncertainties and risks as the planned subsurface targets contain multiple exploration, appraisal, and development objectives. The total cost of the programme is estimated at around US$26 million.

• The Group is progressing with a tie-back project, budgeted for c.US$5m of capital expenditures. It will allow for the first ever third-party feedstock from Ural Oil & Gas LLP (“Ural OG”) to be received for treatment in the Group’s facilities with an expected start in Q4 2023.

• Whilst not itself a target of sanctions imposed in connection with the conflict in Ukraine, Nostrum continues to monitor the current and evolving lists of individuals and entities who are subject to sanctions with a view to compliance by the Group with all applicable sanctions and to ensuring that the Group’s ongoing activities are not materially affected by such sanctions.

• Safety of all staff and contractors as well as focus on conducting sustainable operations remain the Group’s priority.

Sustainability

• Zero fatalities among employees and contractors during operations in H1 2023 (H1 2022: zero).

• Zero Lost Time Injury (“LTI”) in H1 2023 (H1 2022: zero).

• One Total Recordable Incident (“TRI”) in H1 2023 (H1 2022: two).

• 2,277 tonnes of air emissions emitted in H1 2023 against 6,309 tonnes permitted for 2023 under the Kazakhstan Environmental Code.

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

“We are continuing with the execution of our operational programme and pleased with the milestones we have achieved during this reporting period.

The second half of 2023 has already started with the busy schedule with the launch of an appraisal programme at the Stepnoy Leopard Fields, the initial production gains following the recent launch of our Gas lift system expansion as well as the approval of the limited-scale drilling programme at our Chinarevskoye Field.

Our focus will remain on our cost optimisation to help manage liquidity while progressing with the execution of our mixed-asset energy strategy and realising value for all our stakeholders.”

Sales volumes
The sales volume split for H1 2023 was as follows:

The difference between production and sales volumes is primarily due to the internal consumption of gas.
