Operational Highlights By Segment

• The ongoing COVID-19 pandemic and its impact on the global economy have resulted in volatility and significant disruption in the oil and gas market • The pandemic negatively affected the global economy and the oil and gas market; while the global economy as well as oil and gas prices have begun to recover, there is a lag in the recovery in the demand and pricing for our services to this sector, which is expected to remain weak in 2021 and possibly beyond • We have responded by responsibly reducing our cost base, including warm stacking our vessels during idle periods and cutting capital expenditures and targeted SG&A spending • We continue to take what we believe to be appropriate steps to protect our employees, customers and balance sheet COVID & MARKET EVENTS 10

22 The ongoing COVID pandemic and its effect on the offshore oil and gas market, combined with sector uncertainty relating to regulatory changes by the new U.S. administration, suggest a year that will be more challenging than 2020. Our customers’ spending levels currently remain low, providing even more challenges in a year in which three of our long-term Well Intervention contracts expire. Key expectations / assumptions for 2021 include the following: • Total backlog at June 30, 2021 of approximately $291 million; $153 million expected to be realized during remainder of 2021 • North Sea – prioritizing work and expecting good seasonal utilization on the Well Enhancer, balancing customer requirements and scheduling needs; targeted opportunities on the Seawell in Q3, • Gulf of Mexico – prioritizing utilization on the Q5000, balancing customer requirements and scheduling needs, with expected gaps in schedule on both vessels • Brazil – 120-day contract extension on the Siem Helix 1 with Petrobras into mid-August at reduced rates; Siem Helix 2 on contract into mid-December • Robotics – intermittent renewables work with expected fewer site clearance days compared to 2020 2021 OUTLOOK

23 2021 OUTLOOK – WELL INTERVENTION • Q4000 (Gulf of Mexico) – vessel has contracted backlog during Q3 with intermittent scheduling gaps and expected utilization into Q4; identified opportunities thereafter on various work scopes • Q5000 (Gulf of Mexico) – vessel has contracted work through mid-August with identified opportunities thereafter with expected scheduling gaps • IRS rental units (Gulf of Mexico) – 15K IRS opportunities identified in Q4; 10K IRS expected to remain idle • Well Enhancer (North Sea) – vessel has contracted backlog through mid-August with opportunities identified into Q4 • Seawell (North Sea) – vessel idle during July with scheduled backlog beginning August and into September; subsequently available in the spot market with identified opportunities into Q4 • Q7000 (West Africa) – vessel operational in Nigeria with contracted work expected into October; subsequent West Africa opportunities identified • Siem Helix 1 (Brazil) – under contract with Petrobras through mid-August; regulatory dry dock expected following the end of the contract extension • Siem Helix 2 (Brazil) – under contract for Petrobras through mid-December

24 • Grand Canyon II (Asia Pacific) – vessel expected to perform ROV support work for decommissioning project offshore Thailand through the remainder of 2021 • Grand Canyon III (North Sea) – vessel expected to continue performing trenching work in the North Sea into December with good utilization expected during the remainder of 2021 • Renewables site clearance – site clearance work (boulder removal) on North Sea wind farm utilizing one vessel of opportunity expected to continue into Q4; follow-on site clearance work expected into December • Spot vessels – cable installation project in Guyana beginning August; other spot vessel opportunities including UXO work identified during second half 2021 2021 OUTLOOK - ROBOTICS

25 2021 Capital additions are currently forecasted at $20-$35 million, consisting of the following: • Maintenance Capex – $15-30 million related to regulatory inspection costs of our systems and equipment and other maintenance capital • Recompletion Capex – $5 million of recompletion costs on one of our Droshky wells • Capital additions during remainder of 2021 expected to be $10-$25 million Balance Sheet • Our total funded debt1 level is expected to decrease by $32 million (from $346 million at June 30, 2021 to $314 million at December 31, 2021) as a result of scheduled principal payments • Credit Facility expiration and $28 million Term Loan maturity date December 31, 2021 • Tax refund related to the CARES Act of $12 million expected in the next 12 months ($7 million collected during Q1 2021) 2021 OUTLOOK: CAPITAL ADDITIONS & BALANCE SHEET 1 Excludes unamortized issuance costs

Non-cash impairment losses on goodwill and other long-lived assets and gains and losses on equity investments are also added back if applicable. To arrive at our measure of Adjusted EBITDA, we exclude the gain or loss on disposition of assets and the general provision for current expected credit losses, if any. In addition, we include realized losses from foreign currency exchange contracts not designated as hedging instruments, which are excluded from EBITDA as a component of net other income or expense. We define free cash flow as cash flows from operating activities less capital expenditures, net of proceeds from sale of assets. We use EBITDA and free cash flow to monitor and facilitate internal evaluation of the performance of our business operations, to facilitate external comparison of our business results to those of others in our industry, to analyze and evaluate financial and strategic planning decisions regarding future investments and acquisitions, to plan and evaluate operating budgets, and in certain cases, to report our results to the holders of our debt as required by our debt covenants. We believe that our measures of EBITDA and free cash flow provide useful information to the public regarding our operating performance and ability to service debt and fund capital expenditures and may help our investors understand and compare our results to other companies that have different financing, capital and tax structures. Other companies may calculate their measures of EBITDA, Adjusted EBITDA and free cash flow differently from the way we do, which may limit their usefulness as comparative measures. EBITDA, Adjusted EBITDA and free cash flow should not be considered in isolation or as a substitute for, but instead are supplemental to, income from operations, net income, cash flows from operating activities, or other income or cash flow data prepared in accordance with GAAP. Users of this financial information should consider the types of events and transactions that are excluded from these measures.

We continue to implement and improve Environmental, Social and Governance (“ESG”) initiatives and disclosures throughout our business. We understand we have an important role to play as a steward of the people, communities and environments we serve, and we regularly look for ways to emphasize and improve our own ESG record. We incorporate ESG initiatives into our core business values and priorities of safety, sustainability and value creation with a top-down approach led by management and our Board of Directors. We emphasize constant improvement by continually striving to improve our safety record, reducing our environmental impact, and increasing transparency. In 2020, we maintained a low Total Recordable Incident Rate and expanded our business with renewable energy customers. Our efforts are published in our Corporate Sustainability Report and Corporate Sustainability Summary Update, copies of which are available on our website at www.HelixESG.com/about- helix/corporate-sustainability.
