02/11/2021 - Helix Energy Solutions Group Inc.: 2021 Corporate Sustainability Report

Without the resilience and innovation of our teams we would not have had the successful year we had, demonstrated by our solid results and strong safety metrics.

Resilience

Like many, our onshore offices were shut down globally in the face of the pandemic. Our offshore workforce was required to quarantine, test for COVID-19, and wear masks, among other protocols. Despite the changes and our ever-evolving responses to keep our people safe, our employees rose to the occasion and were resilient against not only a pandemic that changed almost every aspect of their lives but also significant uncertainty in the energy market. We were able to persevere both personally and professionally, relying on our core values of Safety, Sustainability and Value Creation.

Safety

As a company and as management, it is our duty to provide our employees with the necessary tools to succeed, and in 2020 the health and safety of our employees, customers, suppliers and their respective families at home and at work were at the forefront of our operations each and every day. Despite a challenging atmosphere we saw our Total Recordable Incident Rate ("TRIR") remain effectively flat and our safety metrics continuously improve. We bolstered our traditional safety requirements with COVID-specific protocols and implemented those protocols through Helix's 4 Pillars

of Beliefs, Language, Workplace and Methodology.

Sustainability

In 2020, we tracked our Greenhouse Gas ("GHG") Emissions for 2019 and 2020 to establish our baseline carbon footprint globally. This Corporate Sustainability Report ("Report") discloses not only our 2020 results but also our 2019 results. 2020 provided a more comprehensive view into our emissions data to validate our baseline information, while 2019 is more representative of a typical year for Helix. Our 2020 GHG results, while positive in reflecting lower emission numbers than those of 2019, do not necessarily depict Helix's current GHG Emissions picture and the progress we are targeting in the coming years. The lower emissions numbers in 2020 are due to a variety of factors, including lower vessel utilization during the pandemic and the downturn in the oil and gas market, but these factors may not be replicated in subsequent years. As a result, we determined 2019 was more representative than 2020 and should be used as the baseline to measure our target emissions reductions over the coming years. We believe this will provide our stakeholders with the most accurate picture of our emission targets and sustainability efforts.

Value Creation

At Helix, we create value through not only the revenues from our services, but also our support of more carbon-neutral energy sources, all presented with accountability and transparency to our stakeholders. This Report sets out tangible targets designed to maintain our accountability for future action and provides transparency that the investor community rightfully demands. While we continue to provide oil and gas support services, over the past decade we have expanded our support of the offshore renewables sector. In tandem with this expanded focus, we have concentrated on our GHG Emissions and the important role they play in our overarching goals to provide value to our stakeholders. We understand that setting targets to decrease our GHG Emissions provides value to us as a company, but it is also valued by those who support us and invest their time, money and energy with us, including our employees, investors and the community at large. In sum, the model we strive to create value for our stakeholders is multi-faceted and is built on our services, revenues, disclosures, transparency and accountability.

Innovation

While 2020 challenged us with a variety of obstacles, it also forced us to innovate to protect the health of our workforce and maintain our commitments to our customers. Our Quality, Safety, Health and Environmental ("QHSE") teams were instrumental in proscribing the protocols necessary to maintain the health and safety of our workforce on- and offshore. For Helix this meant closing

all our onshore offices globally and working from home for over a year. At this time, our US and UK onshore offices have reopened fully and we continue to evaluate phased reopenings in Brazil and Singapore.

For our offshore workforce, this meant quarantining and testing prior to any mobilization to a vessel, mask wearing while on the vessel, frequent temperature tests and social distancing. The safety of our workforce was our primary goal in 2020, and our safety statistics demonstrate our commitment to that goal.

In 2020, we protected our vessels against the mobilization of 289 people who failed their initial COVID-19pre-screen and administered over 10,000 COVID-19 tests through third-party contractors to offshore employees and subcontractors. This was in addition to testing undertaken by our clients.

While 2020 was a challenge, we as a company, through the hard work and resilience of our employees, met that challenge and persevered. We continue to use the lessons learned from our experiences in 2020 to promote Safety, Sustainability and Value Creation for all our stakeholders, and look forward to reporting back on our continued sustainability initiatives for years to come.
