Financials figures presented for 2025 are unaudited.

Forward-looking statements do not guarantee future performance and involve risks and uncertainties. Actual results may differ materially from projected results due to certain risks and uncertainties. Further information about these risks and uncertainties are set forth in our most recent annual report for the year ending December 31, 2024.

Land Drilling preserved cash generation despite reduced activity

However, oil takeaway capacity from Vaca Muerta grows rapidly #thousand bpd capacity¹

Key takeaways

Current focus is on infrastructure and takeaway capacity	▪ Investments and cash allocation towards export capacity is current priority for operators ▪ Significant increase in oil and gas export pipeline and port capacity is ongoing ▪ Increased drilling activity required to fill pipelines
Growth in drilling set to rebound from 2026	▪ Rig count in Argentina down by about 20% YTD ▪ Oil production in Vaca Muerta up 24% YoY (Q2) ▪ We expect growth to rebound in H2 2026 as focus again shifts towards drilling and completion activity
Land Drilling managed to preserve cash flow generation	▪ Rightsizing of business in the south completed with modest positive net impact on cash flow in 2025 ▪ Both Vaca Muerta and the South is cash positive ▪ 75-80% of Land Drilling EBITDA and cash flow comes from Vaca Muerta business
