EBITDA was above the midpoint of our guidance, despite a challenging environment in the Middle East. Our intense focus on execution and cost management produced a 200-basis point sequential improvement in EBITDA margin to over 22%. We converted over 60% of EBITDA to cash, 10-percentage points higher than in Q1 2025, demonstrating the improvement in the quality of our earnings driven by our strong focus on operational efficiency and working capital management. After repurchasing $107m of our shares, we increased our net cash position to $67m at the end of the quarter. “While there is much uncertainty around the situation in the Middle East and the impact on global economic growth, I am confident that our business can adapt more rapidly than before and take advantage of the improving medium-term outlook we see ahead. Our local presence in key markets, including Saudi Arabia and the UAE, enables us to continue serving our largest customers in the region. Meanwhile, our teams are working closely with customers to find alternative solutions for deliveries served from outside the region, mitigating the negative impact on our volumes. “In International markets outside the Middle East, we see high levels of tendering activity for offshore and deep-water projects which underpins our expectation for higher bookings in the second half of 2026 and beyond. “In the US, bookings remain highly robust, and we are seeing early signs of activity growth. OCTG imports continue to decline, especially for seamless products, while new trade investigations will further enforce fair competition in the market. Improving fundamentals in this market will lead to pricing upside in the third quarter. “In New Energies, we signed a record Long-Term Supply Agreement with Fervo Energy worth up to $800 million in potential revenue by the end of the decade. This follows the announcement in January of our partnership with XGS, further demonstrating the clear commercial momentum in geothermal energy driven by the need for reliable, clean, baseload energy to facilitate datacenter build-out in the US. I am pleased to announce that Vallourec will host a deep dive on the geothermal market and our favorable positioning on June 15th to further illuminate this long-term opportunity for our investors. “Looking ahead, we expect our customers to respond to rapidly tightening oil &amp; gas supply fundamentals and countries around the world to prioritize energy security. This gives us confidence that we will see higher levels of drilling activity in both the short and medium term. With our industrial footprint close to our markets and premium technology offer, alongside ongoing efforts to improve Vallourec’s operations and capture rapidly expanding addressable markets in New Energies, we are well positioned to drive further value creation.
