• Potential Improvements in 2023 1 We continue to expect 2023 to be substantially better than 2022, based on the following: • Brazil –Both vessels expected to be working in intervention mode at profitable rates in 2023; expected EBITDA improvement $55 to $65 million in 2023 • Q7000 –vessel expected to have improved rates during 2023 inclusive of paid mobilization with expected EBITDA improvement $17 to $27 million • Shallow Water Abandonment –Full year of contribution by Helix Alliance in 2023, with EBITDA expected to be $30 to $50 million in 2023, which would represent an incremental EBITDA benefit of $15 to $35 million compared to 2022 outlook • Utilization – Well Intervention increased utilization expected in 2023 compared to 2022, including the Q7000 , due to anticipated fewer days of regulatory maintenance and transit • Rates –Overall Well Intervention rates expected to be up 30% to 45% for full year 2023 compared to rates at the beginning of 2022 • Robotics –Higher ROV utilization expected in 2023 • Production Facilities –Expect continuation of Helix Producer I for 2023; ongoing oil and gas production from acquired interest in Thunder Hawk Field and decommissioning backlog with remaining Droshky wells 1 These potential improvements include key assumptions and estimates. Any significant variation from these key assumptions andestimates could limit our ability to achieve such improvements. BEYOND 2022 33
