Our journey is just beginning, but I am so proud of all we have done in just under two years. ”

Of all responsibilities that fall within my role, I think authentic, meaningful engagement with my colleagues at Safe Harbor is one of the most important.

A corporate sustainability program, even if informed by external benchmarks, should emanate from the intrinsic values of our people – my job is to harness that energy. What ideas do our Teammates have for environmental stewardship? What is their vision for our properties, and how does that vision overlap with Safe Harbor’s global sustainability commitments?

This report showcases some of the ways our Teammates contributed to environmental stewardship even before our program launched – so in many ways, the motivation for a cleaner, sustainable future was at Safe Harbor before my time. That said, I am thrilled that so many Teammates have stepped up to be involved in our new corporate initiatives, like the Coastal Habitat Restoration Program ("CHRP") and our sustainability-related working groups.

Nevertheless, we are not shy about the challenges ahead. The regulatory landscape is changing quickly, and not every

sustainability challenge in our industry has a clear-cut solution.

At each juncture, however, we are rising to the challenge and asking first, ‘what is the right thing to do,’ and second, ‘what is the right solution to the problem?’

Our journey is just beginning, but I am so proud of all we have done in just under two years.

PRIORITIES & ENGAGEMENT

Ongoing materiality assessments are conducted at the enterprise and business unit levels of our parent company, Sun. Consistent with Sun’s approach, Safe Harbor conducts its own ongoing materiality assessments to identify sustainability topics that are important to key stakeholders. Consideration is given to each topic regarding the potential impact on our business, whether direct or indirect, through our engagement with stakeholders.

Currently, our top material topics are:

• Coastal & marine ecosystem conservation

• Environmental compliance

• Teammate well-being

• Member service

• Health & safety

We take advantage of opportunities to engage stakeholders – including Teammates, Members, regulators, and local communities – as they arise in the course of developing our sustainability programming.

Additionally, we communicate with Teammates about ongoing sustainability programming and achievements through several internal communications platforms, including The Bridge, internal newsletters, and communications from leadership.

We aim to lead by example when it comes to caring for the natural environment in which we operate. In this section, you will learn about our efforts to reduce our overall emissions footprint over time, manage and adapt to climate-related risks, reduce electricity consumption, and invest in renewable energy and electrification. You will also learn about our approach to enhancing coastal and marine habitats at or near our operations, as well as some of our Teammates who embody an exceptional stewardship ethic in their day-to-day roles at Safe Harbor.

OUR CLIMATE STORY

Decarbonization: Charting a Course

Today, every business must consider climate mitigation and adaptation as part of its strategy for operating in the 21st century. In 2022, our parent company, Sun, committed to achieving:

Carbon neutral by Net zero emissions by

We plan to contribute to these goals through various actions that align with our Framework, including investments in energy efficiency measures, zero emission technology and renewable energy projects where feasible.

Climate Risk & Resilience

We cannot ignore the physical risks to our people and places posed by climate change. Those risks hit home in 2022 as Hurricane Ian devastated the west coast of Florida, severely damaging properties and communities, and disrupting the lives of our Teammates in the Southeast.

Safe Harbor is working toward alignment with the Recommendations of the Task Force on Climate-Related Financial Disclosures ("TCFD"). Like our parent company Sun, we use TCFD to organize our response to climate impacts and to ensure appropriate management and consideration of a broad range of climate-related risks and opportunities. Also, the TCFD disclosure process helps us identify areas of climate risk management that require further improvement. For more information on how Safe Harbor aligns to the TCFD, please contact cajax@shmarinas.com.

Second, we regularly invest in construction and repair of critical infrastructure at our properties, including docks, seawalls, bulkheads, and stormwater management systems as needed. In 2022, we invested in:

Bulkhead & seawall replacements Docks upgraded from fixed to floating

But that is only part of the story. In late 2022, we set out to develop a formal climate risk management and resilience strategy for our business.

2023 GOAL: Complete GIS mapping of physical climate risks & develop preliminary resilience plan for three pilot marinas.

As the world's largest owner & operator of marina properties, we cannot ignore the physical risks to our people and places posed by climate change.

In 2023 we aim to: This process will provide:

UNDERSTAND ACCURATE INFORMATION

Our exposure to physical climate risks like flooding and sea level rise

ANALYZE

The long-term threats to our properties using globallyrecognized climate scenarios

About existing and potential exposure to physical climaterelated risk

INFORMED ANALYSIS

About where capital allocations for new resilience-related projects, upgrades and retrofits are most urgently needed

IDENTIFY IDEAS & OPPORTUNITIES

Marina-specific sensitivity factors that contribute to increased exposure

To address risks related to the to resilience and the transition to a low carbon economy

The environmental focus of our framework is characterized in large part by a commitment to improving coastal and marine habitats at or near our operations.

ENHANCING MARINE & COASTAL HABITATS

As the world moves toward a better understanding of the link between nature and financial stability, we have committed to reducing our impact on a key stakeholder — the environment.

In 2022, we made significant strides toward developing our approach to stewarding the environments in which we operate. We hired an expert technical team of Foth Infrastructure and Environment, Horsley Witten Group and RPS Group to help design and implement a scalable Coastal Habitat Restoration Program ("CHRP"), beginning with a pilot program in Rhode Island.

This program involves:

• Categorizing our marinas based on operational characteristics and potential for habitat enhancement projects.

• Developing a list of potential projects, ranging from green stormwater infrastructure to “living” breakwaters, that can be matched with our marinas based on above categorizations.

• Choosing appropriate Key Performance Indicators ("KPIs") to measure the success of each project over time.

We are thrilled to report that the CHRP pilot is off to a strong start.

By the end of 2022, the Safe Harbor and Foth teams conducted four internal stakeholder meetings, 16 property visits, and reviewed specific project proposals for select properties in the Rhode Island pilot program. We also held one meeting of our Coastal Conservation Advisory Board (“CCAB”), consisting of industry and nonprofit representatives, and solicited feedback on preliminary project proposals and overall progress.

We expect the pilot program will culminate in distinct projects at 3-4 properties that will enhance natural habitat at the marinas and in the surrounding environment.

A strong conservation ethic is not new for many of our Teammates, however. Many of our General Managers are involved in local environmental partnerships and projects that predate acquisition by Safe Harbor.

STEVE ROWE GM OF SAFE HARBOR GREAT ISLAND

The Gulf of Maine, home to five Safe Harbor properties, is one of the fastest-warming bodies of water on Earth, endangering both marine environments and the local communities that depend on them for fishing, lobstering, tourism and recreation.

It comes as no surprise, then, that Steve Rowe, General Manager of Safe Harbor Great Island is constantly thinking

about how our company can better manage its environmental impacts.

“I have always personally had an interest in environmental issues,” he said. “As we get bigger and have a larger footprint on the water, we need to push the envelope on environmental controls.”

Safe Harbor Great Island sits within the Quahog Bay, one of the many inlets off of the much larger Gulf of Maine. But Steve is not just concerned about the threats to marine biodiversity.

Sustainability is very much about the local community too. Steve’s marina is one of the biggest employers in the town of Harpswell, Maine.

“ We need to be able to reassure the local community that as Safe Harbor expands, we are doing so in a way that is beneficial to the environment.

“We need to be able to reassure the local community that as Safe Harbor expands, we are doing so in a way that is beneficial for the environment,” he said. “I want to tell people that the (Quahog) Bay will getter better, cleaner as we get bigger and provide more jobs. Engagement of Members and local communities is critical.”

INTRODUCTION 1 | SAFE HARBOR SUSTAINABILITY 2 | PLACES & STEWARDSHIP SAFE HARBOR SUSTAINABILITY | 2022 32

One could say that Steve’s inclination toward environmental concerns is natural given his background. After nearly fifteen years managing air quality controls and running the Environmental Services Division of General Electric, Steve and his family took a chance at a new beginning.

“My wife and I looked at ski areas, vineyards, and boatyards – we wanted to return to an entrepreneurial lifestyle and to run our own services business,” he said. “We found Great Island Boat Yard in 2005, bought it, packed our bags and left Kansas City for Maine!”

Steve is enthusiastic about Safe Harbor’s sustainability focus, especially as other industry-wide environmental standards have fallen short.

“There used to be a really strong Maine Clean Marina program and the Division of Environmental Protection would do inspections with the marine trades association, but that program fell apart,” he said. “So environmental best practices were left up to each individual marina, which was less than ideal.”

Given his background, Steve understands the challenges that lie ahead.

POWERING OUR NETWORK

Energy Overview

Global events of 2022 highlighted the urgent need to reduce energy consumption and make key investments in energy efficiency measures and clean energy alternatives.

The section includes several examples of our progress in these areas.

Total electricity consumption in 2022

Total water consumption in 2022

Green Summer Initiative

In response to the soaring costs of global energy prices, our team set ambitious goals to reduce electricity usage and cut utility costs in the latter half of 2022.

First, our Operations leaders coordinated with General Managers to communicate goals and expectations to Teammates and Members at our properties and to crowdsource ideas on how to cut consumption and improve efficiency. We circulated “pro tips” to Teammates, which included such measures as turning off lights when not in use, switching computers to “sleep” mode, and changing thermostat settings. Members were also encouraged to reduce electricity usage on their vessels.

Our targets included a 5% reduction in July followed by a 10% month-tomonth reduction for August through December 2022. Through this initiative, we exceeded those targets and achieved 10.8% overall reduction in electricity use in the last two quarters of 2022.

Solar

Our biggest opportunities for on-site generation lie with our large upland storage buildings. We are nearing completion of the 3.74 GW per year, 200,000 square foot rooftop solar installation at Lauderdale Marine Center (LMC) in Florida – the power generated by the panels accounts for approximately 24% of LMC’s overall energy needs.

Additionally, in late 2022, Safe Harbor engaged outside firms to analyze our properties for scalable solar opportunities based on original building construction, utility costs, available rebates and state incentives programs. As we move forward, our aim is to initiate more projects at qualified properties based on the data from these site assessments, especially at larger service properties that require more energy to operate.

Electrification

We have seen rising demand for electric vehicle ("EV") charging infrastructure at many properties in our network. Given the upfront costs, discrepancies in demand, and variable incentives available across the United States, scaling this infrastructure presents strategic challenges. We will continue to engage with vendors to determine the feasibility of installing EV chargers in select locations.

Our electrification efforts are not limited to EVs, however. We are at the forefront of piloting all-electric heavy equipment and vessels where feasible. The following are a few examples of larger investments made in 2021-22:

In the future, our team will consider bulk product purchases based on proven performance, cost, and scalability.

PROMOTING CLEAN OPERATIONS

Excellent environmental compliance practices are essential to our long-term vision for sustainability at Safe Harbor Marinas.

Our business is subject to a variety of environmental laws and regulations, including the Clean Water Act and associated stormwater regulations. Among other things, each marina has a proper Stormwater Pollution Prevention Plan ("SWPPP") and Spill Prevention Control and Countermeasure Plan ("SPCC") in place, where applicable.

Our policy is that Teammates and Members properly manage used oil, antifreeze, off-spec fuel and other universal waste, in addition to black and gray water. We take care to manage materials that are abandoned on-site, such as unidentified aerosols, by identifying, testing (if needed), and following proper procedures for disposal.

Excellent environmental compliance practices are essential to our long-term vision for sustainability at Safe Harbor Marinas.

Clean Marina Certification

Over the last two years, we have made consistent progress toward network-wide Clean Marina certification.

Currently, properties may choose between pursuing certification through the Association of Marine Industries’ ("AMI") Clean and Resilient Marina program, the equivalent state Clean Marina program if available, or both. Our Environment, Health and Safety ("EHS") Department leaders are trained and certified as “Clean and Resilient Marina” professionals, and as such, authorized to conduct certification audits.

The AMI Clean Marina checklist requirements are rigorous and exceed basic compliance standards. Checklist items include habitat restoration and conservation measures, use of “environmentally-neutral” materials, “green” stormwater management, and nature-based landscaping. Beginning in 2023, new acquisitions will be required to implement all Clean and Resilient Marina Best Management Practices ("BMPs").

2023 GOAL: 100% properties Clean Marina certified through AMI or equivalent state program.

Waste Management

The nature of our business includes handling and disposal of various waste types, including gas, diesel fuel, used oil, black water and hazardous waste. We have internal policies and procedures to properly manage these wastes in compliance with applicable laws and regulations.

Waste management is an area in which we aim to improve. Late last year, we engaged Engie Impact to assist with waste characterization audits and developing a waste baseline. This service will allow us to (i) better understand our various waste streams and collect baseline operational waste estimates, and (ii) develop a strategy to increase waste diversion practices throughout our business.

We have internal policies and procedures to properly manage various waste types in compliance with applicable laws and regulations.

RESPONDING TO HURRICANE IAN

Our Preparation

When it comes to preparing for hazardous weather events like Hurricane Ian, our people always come first. In late 2022, our preparedness efforts for Ian involved notifying Members and shutting down operations in advance of landfall. This and other actions gave our Teammates the necessary time to make personal preparations for the storm.

With regard to our properties, more preparation lessens the overall impact. To that end, we maintain a Hazardous Weather Plan (“Plan”) that details management practices to prepare individual properties for severe storms.

Pursuant to the Plan, key Safe Harbor personnel held daily calls with Operations leaders in affected regions and provided regular briefings on changing weather conditions and preparation measures in the days and hours leading up to Ian making landfall. Priority actions included removal of vessels from critical areas. Our team was also diligent about shutting off electricity and water, draining fuel lines where they passed over water, as well as securing Hazardous Materials Management (HAZMAT) containers.

The Aftermath

In the immediate aftermath, many Safe Harbor Teammates gathered in Fort Myers, Florida to assess damage and mitigate further hardship.

Having engaged remediation contractors and vessel salvage services prior to the storm, we were able to start clearing flooded structures of wreckage and raise sunken vessels almost immediately. Within just a few days, all seven affected Safe Harbor properties were deemed safe and reopened to the public.

Additionally, the crew of Safe Harbor Pineland on hard-hit Pine Island teamed up with emergency management officials and the US Coast Guard to ferry residents off of the island using the marina’s water taxi fleet, a process which lasted well into the following week.

Hurricane recovery cannot proceed with boats strewn on land and throughout navigable waterways. Moreover, damaged vessels that remain in water present significant environmental hazards and business risks.

To help solve this problem, we converted a 7-acre leased property into a temporary vessel triage center near downtown Fort Myers, aptly named “Port Phoenix.” Prior to bringing salvaged vessels on site, our team swiftly developed and implemented appropriate environmental, safety and compliance plans. Other preparation included bringing in storage tanks for contaminated bilge water, pumps to drain fuel from vessels, HAZMAT containers and spill supplies, as well as constructing a basin for bottom washing.

At the time of publishing this report, Safe Harbor Port Phoenix continues to provide a location for hurricane-damaged vessels to be hauled out, stored and repaired, leveraging our team’s industry-leading knowledge in marine services and creating multiple jobs in the process.

As General Manager of a property that sits on the edge of a large threatened ecosystem, Jaret Rogers knows firsthand the destructive effects of poor environmental stewardship… and extreme weather.

Safe Harbor Burnt Store was heavily damaged by high winds and storm surge from Hurricane Ian, which devastated large portions of Florida’s west coast in late September 2022. Among other things, Jaret’s property suffered losses that included the destruction of docks, seawalls and numerous vessels.

“There was so much debris that you couldn’t even reach with heavy equipment,” he said. “There were also parts of houses and cars that were leaking oil and gas slowly into the bay. Each day we took our workboats out to collect debris that was floating, but the tide would just come back in and there would be so much more.”

JARET ROGERS GM OF SAFE HARBOR BURNT STORE

Unfortunately, marine debris was just the beginning.

“Storm surge brings a lot of nastiness from onshore and moves it offshore. It is possible that we will see some bad red tides and massive fish kills as a result.”

Jaret is all too familiar with the problems that red tides create for the marina and surrounding community.

“In the past, the local residential community around our marina was not really aware of the water quality issues affecting the marine environment next to us,” he said. “But about four years ago, red tide actually made it to our marina, and the fish kill was very visible. When residents’ front porches smelled like dead fish, that’s when the locals really understood the impact. We literally spent thousands of dollars scooping up dead fish.”

SAFE HARBOR BURNT STORE

Gulf of Mexico

Hurricane Ian may have exacerbated certain environmental hazards, but raising awareness about environmental impacts is not new for Jaret and his team.

Safe Harbor Burnt Store sits within the Charlotte Harbor estuary, an approximately 270 square mile bay on the west coast of Florida fed by the Caloosahatchee River, among others. Jaret explained that pesticides and fertilizers used in agriculture end up in the river, which filter into the bay before entering the Gulf of Mexico. The excess nitrogen creates serious water quality issues, including red tides.

“My concern is, first and foremost, for Mother Nature,” he said. “Our water and fisheries are unhealthy and dying, and sometimes it seems that no one really cares.”

Jaret and his team have made several efforts to raise awareness

I think our role is to raise awareness, because that is key. The health of the natural environment is about our future – my son's future.

among Members and neighbors. In 2022, his team hosted an Earth Day party, complete with metal straws, leaf-based confetti, and recycled paper tablecloths.

Safe Harbor Burnt Store also hosts an annual meeting for Members and local residents to learn about local water quality issues and has nine 96-gallon recycling totes at strategic locations across the marina with signage encouraging Members to recycle.

“I pick up plastic grocery bags around our marina every day,” he said. “We do the best we can.”

The marina is also home to several artificial reefs and reef balls below

the seawall and under two of the docks, though Jaret is not sure whether they moved during Hurricane Ian.

When asked about important lessons for Safe Harbor in the wake of Ian, Jaret thought for a moment.

“These storms are only getting worse, so the more we can do to prepare, the better,” he said. “We are making some important changes like replacing wood and fiberglass pilings with steel.”

Jaret is also optimistic that Safe Harbor, with its large footprint, can have a positive impact on the environment going forward.

“I think our role is to raise awareness, because that is key,” he said. “The health of the natural environment is about our future – my son’s future.”

JAMES PHYFE CHIEF RESOURCE OFFICER

Safe Harbor has developed a unique culture in a short period of time. Because we have grown tremendously with acquisitions over the past seven years, it is not always easy to assimilate new faces so they feel immediately valued and respected. ‘One Safe Harbor’ is our company’s approach to welcoming new Teammates into the company by sharing both the excitement of what we set out to achieve and the magnitude of the work in front of us.

Everyone who joins Safe Harbor knows that we derive great pleasure from our accomplishments. We want our people to share that enthusiasm, and we are not afraid to celebrate our successes with them. That builds a culture of motivation that constantly challenges us to outperform our previous achievements. And that is addictive.

“

Everyone who joins Safe Harbor knows that we derive great pleasure from our accomplishments. We want our people to share that enthusiasm, and we are not afraid to celebrate our successes with them. ”

In our efforts to continuously improve, we launched a Teammate engagement survey in 2022 to measure how well we are spreading this enthusiasm through the company. Designed in a way that will allow repetition over time, this survey should not only provide a window into engagement today but also into changes we can make in the future. At Safe Harbor we believe we are doing something truly transformational and we hope everyone will share in that excitement.”

TEAMMATES

Strength in Diversity

At Safe Harbor, we seek the best for every Teammate we serve. That means we hire, train and invest into individuals whose values and character add to our culture of high intensity, high reward, and genuine care for one another. We welcome ALL without bias toward race, religion, age, national origin, veteran status, sexual orientation, or any other categorization.

We believe that we are able to fulfill our unique company mission because our Teammates reflect diversity of thought, background, and experience.

Our Teammates earn and retain their roles through their demonstrated desire and ability to serve one another and our Members with excellence. Once we have made an employment offer to a Teammate, we commit to training and developing that person with the aim of being party to their vocational and personal flourishing.

In sum, our differences allow us to meet today’s business challenges through innovation born of constructive dialogue between Teammates with varied experiences and skill sets, but a common objective to build something special in the world for our Members and for each other.

Hiring and retaining Teammates with strong character is a top priority for Safe Harbor. Strong character is, among other things, the ability to put others first, particularly in times of great adversity.

Nowhere is this better exemplified than by our Teammates in Arkansas who, in the wake of tragedy, have found hope and offered it to others.

Several Teammates from Safe Harbor Brady Mountain (AR) recently founded ‘Braydon House1,’ a foundation external and independent of Safe Harbor to honor the life and legacy of Braydon Anderson, a son, brother, friend, mentor and Safe Harbor Teammate.

The Braydon House mission is to provide a safe haven to inspire, mentor and empower individuals to achieve lifelong success. Specifically, the organization aims to provide stability, mentorship, scholarships and other resources to enable people to achieve prosperous careers.

“As a young man, Braydon would take everyone under his wing,” said Steven Anderson, Braydon’s father and General Manager of Safe Harbor Brady Mountain. “My wife and I often say that we would ‘bring home the strays.’ These were often young men who did not have friends or stable home lives. Braydon would bring them home to us. It was just the person he was.”

Braydon tragically passed away in 2021 at age 19.

1Braydon House is an unaffiliated 501(c)(3) charity organization.

Braydon & Steven Anderson

“Some parents say that things get harder when your kid becomes a teenager, but that just wasn’t what it was like for Braydon and me,” said Steven. “He already knew what it meant to respect others.”

In 2022, the Braydon House team organized the First Annual Braydon House Golf Tournament to support Braydon House. The event raised $21,000 with 22 sponsors and 22 players. The Tournament, which will be held annually, is the first step in a much bigger plan to raise funds for Braydon House.

“ ...

we want to provide employment opportunities at the marina and help young people build careers in marine services if they want to.

“Steven and I have worked together as GMs for years,” said Sean McNamara, Regional Vice President for the Southwest Region. “Some of the guys on Steven’s team have had hard home lives and were given a chance to prove themselves and grow into fine young men. They are just naturally doing it without trying up there at the marina –they are natural mentors with great attitudes and kindness.”

“Right after it happened, Sean called me and said, ‘I want to do this,’” said Steven. “We don’t do things like this because it looks good for us – we do it because it’s the right thing to do.”

”

help young people build careers in marine services if they want to. Through Braydon House, we could also provide scholarships if they have other interests.”

But Steven’s first priority is giving back to those that were there for his family in their darkest moments.

“We are currently working with the intensive care nurses that cared for Braydon in the hospital. They were so good to us,” said Steven. “We want to provide the first Braydon House scholarships to their kids, or for them personally if they want to pursue additional education.”

Braydon House presented the first $6,000 in scholarships in December 2022.

While the loss is still felt profoundly by Braydon’s family and the entire team at Safe Harbor Brady Mountain, Steven says that the creation of Braydon House offers hope.

“It will never get easier to talk about. But when someone else recognizes that what we’re doing is the right thing for young people in need, that makes all the difference.”

Serving Our People

As our business grows, we want to ensure that every Teammate has the opportunity to thrive at Safe Harbor.

This year, we conducted our first ever Teammate engagement survey to assess the state of employee well-being at our company and identify areas for improvement. Topics covered included job satisfaction, benefits, diversity and company culture. This data allows us to further refine our relationship with our greatest asset – our people – in a cycle of continuous improvement.

Safe Harbor provides a comprehensive benefits package to full-time employees that includes a 401(k) retirement

plan and match, eight-week paid parental leave, medical, dental, and vision insurance, as well as generous paid time off ("PTO") allowances for hourly and exempt (non-hourly) Teammates. As part of our commitment to Teammate growth, we also provide 30, 60, and 90- day performance reviews to new Teammates and annual performance reviews to all.

Moreover, we want to give all Teammates access to the training they need to grow and develop new skills in their respective roles within our company.

We believe that we are able to fulfill our unique company mission because our Teammates reflect diversity of thought, background, and experience.

Training & Professional Development

Safe Harbor’s training and professional development program underwent a major overhaul in 2022.

We began by surveying Teammates on training needs and preferences. Based in part on that data, we rolled out a comprehensive Monthly Training Calendar that shifted training programs onto a centralized, accessible platform for all Teammates. This new approach facilitates better data collection and visibility, allowing us to expand on training topics and address gaps in our offerings as needed.

In 2022, we also launched The Bridge, a web-based tool developed to consolidate all company systems and resources in one place. In addition to providing quick access to all

platforms used in our operations, The Bridge includes a training database and video library, as well as online forms for direct Teammate feedback. This resource allows us to work smarter and onboard new Teammates more easily by removing inefficiencies.

2023 GOAL: Develop holistic General Manager training.

Investing in Marine Technicians

One of our biggest business risks is the industry-wide shortage of skilled marine technicians. Through our relationships with several top marine trade schools throughout the country, we aim to be part of the solution by reducing barriers to entry into the industry.

Students in these programs learn skills such as advanced composite manufacturing, digital modeling, and marine systems. Students from IYRS, for example, also have the opportunity to participate in a month-long externship at one of our nearby properties.

In addition to scholarships, we offer mentorship from some of the best technicians in the business and a career path for motivated students interested in entering the field and launching their career with us.

Creating Local Jobs

Safe Harbor’s vast national footprint provides many economic opportunities for local communities. Our operations require a variety of skills, ranging from carpentry and rigging, to accounting and marketing services, among other things.

Additionally, as we acquire new properties, our normal practice is to integrate existing marina management and service teams. This approach helps our business maintain strong connections to the cities, towns and regions in which we operate.

OSHA Incident Rates

WORKPLACE SAFETY

Workplace safety at Safe Harbor is paramount because the nature of our business requires operation and handling of heavy equipment and hazardous materials, among other things.

Overview

A copy of our OSHA-compliant environment, health and safety (“EHS”) manual, also called the “Orange Book,” is located at every property in the network. We require all full-time, part-time, and seasonal employees, as well as Members, contractors, and third-party vendors servicing vessels on our properties, to comply with Orange Book guidelines at all times.

Leadership is notified immediately of any incidents or compliance issues as they arise. Every property in the Safe Harbor network has a designated EHS Coordinator that receives regular OSHA training.

Additionally, we maintain a formal EHS Committee that meets regularly to review current EHS practices and potential improvements.

What's New

Our company saw several key EHS developments in 2022. Beginning in 2022, all monthly EHS Coordinator trainings were advertised in general business communications, which increased visibility of safety trainings and reinforced baseline EHS expectations for all Teammates.

We also launched the Regional Vice President ("RVP") “Safety Scorecard” system, which tracks environmental and safety performance at individual properties.

Performance indicators include things like hazardous waste inspections, use of proper personal protective equipment ("PPE"), training frequency and more. In addition to enhancing monthly EHS oversight for specific properties, the Scorecard system ensures that newly-acquired properties identify compliance gaps and remedy them quickly.

Lastly, we further developed our virtual EHS training library that includes recorded training sessions on a wide range of EHS topics.

Safety Training

We require job-specific safety trainings for Teammates where applicable. At present, our monthly EHS Coordinator trainings are offered in both English and Spanish, and we expect to offer more Spanish-language trainings by the end of 2023. Those trainings include:

• Monthly EHS Coordinator trainings

• Marine Travelift Operator training

• Forklift “train-the-trainer” program

• OSHA 10 Certification Trainings

• Shipyard Confident Person ("SCP") training (expected in 2023)

Promoting Member Safety

All Safe Harbor EHS policies and procedures apply to Members servicing their own vessels on our properties in addition to Teammates. To ensure expectations are clearly conveyed, our properties are equipped with proper signage, illumination, and demarcation for vessel maintenance and repair.

Ultimately, our General Managers are responsible for setting an example and enforcing EHS best practices at their individual marinas. Likewise, it is also the responsibility of our General Managers to address safety concerns with Members directly as they arise.

Incident Response

While our goal is always to reduce or eliminate the number of injuries that happen at our operations, incidents occasionally do occur.

When this happens, marina or regional management is the first point of contact, followed by our Human Resources department. Incident reports are then forward to our Risk Management department through an online portal in our risk management platform, Origami Risk, and are shared immediately with leadership. For high-consequence workplace injuries, Safe Harbor investigates and conducts a “root cause” analysis, the results of which are also shared with leadership.

Lastly, in order to promote awareness and future prevention following an incident, we use a company-wide Safety Alert system to notify General Managers when a notable incident occurs.

To ensure safety expectations are clearly conveyed, our properties are equipped with proper signage, illumination, and demarcation for vessel maintenance and repair.

CARMEN GILLS SENIOR FINANCE & ACCOUNTING MANAGER

Prior to interviewing for a new role as Finance and Accounting Manager at Safe Harbor, Carmen Gills was nervous.

However, upon seeing her resume – and the impressive list of leadership and community service roles on it – Chief Accounting Officer Meagan Thompson told her:

“Yeah. I think you can do this.”

“That was nice to hear – it gave me confidence.” Carmen said. “I’ve always been so involved and wanted to continue with that after joining Safe Harbor.”

It did not take long for Carmen to make an impression and to earn greater responsibility. Today, she manages multiple properties on the international team.

But it’s the extra responsibilities that Carmen takes on outside of work that make her stand out.

Carmen has served as Community Affairs Director for a local accounting organization where she has leveraged both her accounting and community leadership skills to improve the everyday lives of people in the greater Dallas community –and she is making a big impact.

In 2022, for example, her local chapter donated over 7,000 school supplies to families in need through the Drive Thru MLK Back to School Fair serving the South Dallas community. Her chapter also prepared over 2,360 meals that were donated and distributed to the homeless.

“I try to find unique areas where I can insert myself and fulfill my passion for service,” said Carmen. “And I think Safe Harbor goes beyond being supportive. I especially love the flexibility and support that Safe Harbor gives me to stay engaged and give back to my community.”

“

Carmen does not stop there. She also participates in a young girls’ college preparatory program through her active involvement with her sorority, coordinates tax service programs for elderly and low-middle income populations in the West Dallas area, and previously organized a donation drive for a local domestic violence shelter.

“All my life I have been a part of programs and organizations that helped shape the individual I am today,” said Carmen. “I truly believe in the saying ‘it takes a village to raise a child.’ My ‘village’ taught me the value of giving back through my time and resources in order to positively impact the lives of others. When I put the focus off of me and onto others, I get a sense of joy and fulfillment that makes my daily life more special.”

I especially love the flexibility and support that Safe Harbor gives me to stay engaged and give back to my community. ”

HOW WE LEAD

As a wholly-owned subsidiary of Sun Communities (“Sun”), Safe Harbor’s highest governing body is a three-person Executive Committee, which includes our CEO, Sun’s CEO and one member of Sun’s Board of Directors.

All executive-level Safe Harbor Teammates, including our CEO, are directly engaged in sustainability oversight by serving on Safe Harbor’s ESG Council (“Council”), the highest sustainability-related governance body at Safe Harbor.

Safe Harbor’s Vice President of ESG is charged with building out sustainability strategy, annual reporting, managing cross-departmental working groups and external consultants, engaging internal and external stakeholders, managing progress against goals, and providing regular semiannual updates to the Council.

Additionally, the Vice President of ESG is responsible for educating the Council on regulatory developments affecting our sustainability program and the business in general.

Our Parent Company

As a member of the Sun portfolio, Safe Harbor’s ESG data and annual highlights are also included in Sun’s portfolio-wide ESG report alongside other Sun subsidiaries. The Sun report can be found here.

While Sun and Safe Harbor collaborate on ESG data collection, Safe Harbor’s Framework is unique and tailored to address Safe Harbor’s material non-financial impacts and opportunities.

ESG Council

Our commitment to growing responsibly can only be realized if our sustainability-related efforts are not siloed within the company.

To that end, the Council consists of representatives from all major business units within Safe Harbor, bringing together the authority and expertise necessary to operationalize all programming and provide oversight;

The Council also convenes semiannually for progress updates on Safe Harbor’s performance and to approve program or investment proposals submitted by the Vice President of ESG. In order to best fulfill these duties, Members of the Council maintain a direct and open line of communication with the Vice President of ESG at all times.

Policies

We expect the highest degree of professionalism from all Teammates, contractors, third parties and joint venture partners at Safe Harbor. To that end, all parties listed above must abide by our Code of Ethics and Business Conduct (“Code”), which includes all policies and guidelines necessary to ensure that our business operates in an ethical and compliant manner.

Our Code is comprehensive, and includes policies and procedures pertaining to the following:

• Ethics reporting

• Non-retaliation

• Diversity & non-discrimination

• Anti-harassment

• Workplace health & safety

• Honest & fair dealing

• Due diligence

• Conflicts of interest

• Gifts & entertainment

• Rules for working with government

• Information & asset protection

• Anti-corruption & bribery

• Anti-money laundering

Information Security

In the fast-changing world of information security and cybercrime, businesses face new threats almost daily. Our information security policies are in alignment with those of Sun and our team incorporates all Sarbanes-Oxley requirements in its policies and procedures. This includes requiring password protection, user access controls, termination of users, a “least privileged access” policy, and a review of user roles each year. Our policy is to maintain

a strong security posture at all times. To that end, we partner with cybersecurity experts to help us protect not just the perimeter, but every email received by Safe Harbor Teammates, and everything in between. Lastly, we maintain strict procedures for addressing data breaches if they occur. We look forward to constantly improving our systems to keep pace with best practices.

We maintain strict procedures for addressing data breaches if they occur. We look forward to constantly improving our systems to keep pace with best practices.

Committees

We depend on close relationships and resource-sharing between key departments within Safe Harbor to make good on our commitments. Key departments include but are not limited to Environment, Health and Safety ("EHS"), Risk, Training, Accounting and Operations.

To that end, some Teammates, including the VP of ESG, serve on more than one of the following oversight committees simultaneously:

• ESG Council

• Enterprise Risk Management ("ERM") Committee

• Environment, Health & Safety ("EHS") Committee

• Coastal & Marine Stewardship Working Group

• Teammate Well-Being Working Group

Industry Leadership

Our Teammates are among the most talented and experienced in the marine services industry.

Because of that expertise, we actively encourage our people to represent Safe Harbor in a variety of local, national and international forums. We are especially eager to be part of the evolving conversation on sustainability in marine services and adjacent industries.

Toward Aligned Procurement

Integrating sustainable principles into our procurement approach is a critical step in ensuring we engage with vendors that meet operational needs and share our vision for a better future.

Safe Harbor works with a vast network of suppliers and third-party contractors, including many small businesses. Beginning in 2023, our goal is to work toward centralizing procurement data by identifying top suppliers and major product categories as a first step.

We recognize that providing information on environmental performance may be challenging for many small businesses we work with. As part of a long-term strategy, we aspire to develop programming to help small suppliers and service providers collect and disclose environmental performance data as needed.

Tax

Oversight of tax obligations is the responsibility of senior Safe Harbor and Sun personnel, working jointly. Our Code provides processes for reporting known or suspected illegal or unethical behavior regarding tax or any other part of the business. Where applicable, we outsource tax compliance to qualified third parties. In Puerto Rico, an unincorporated United States territory with its own tax structure, we partner with local tax specialists to ensure compliance with local tax regimes.

CAROLINA CORRAL RVP OF INTERNATIONAL SOUTH

Growing up on the Commonwealth of Puerto Rico, Carolina Corral understands the importance of caring for the natural environment in business and everyday life.

level rise, for example, affect the amount of land available for growing food, as well as the health of local fisheries. But that’s not all.

“I would watch my mom do small things, like pick up garbage on the beach and recycle glass… just small things,” Carolina said, “You can say those values were inculcated in me at a young age. Today, I compost and recycle, even though Puerto Rico does not have a formal recycling program in place.”

I see a need to do everything we can personally, and as a business, to conduct ourselves responsibly. Every little bit counts.

“Safe Harbor Puerto Del Rey is located on a Caribbean island, so we are in much closer proximity to extreme storms, which are happening more frequently,” she said. “We are also more exposed to the ocean plastics problem and coastal erosion. So, I see a need to do everything we can personally, and as a business, to conduct ourselves responsibly. Every little bit counts.”

Carolina brought that stewardship ethic to the marina business long before assuming her current role as Regional Vice President of International South, based at Safe Harbor Puerto Del Rey.

“Once I entered the industry, I understood that the ocean was our business, and that there is no way that we will survive long-term at the rate we’re going,” said Carolina.

The threats to island nations like Puerto Rico are many. Warming oceans and sea

Her passion for stewardship, in addition to Safe Harbor Puerto Del Rey’s strategic location in the middle of international superyacht routes to and from Safe Harbor properties like Safe Harbor Lauderdale Marine Center and Safe Harbor Charleston City, made Carolina a perfect addition to the Board of Directors of Water Revolution Foundation (“WRF”), an international organization dedicated to promoting sustainability in the superyacht industry through collaborative projects and educational resources.

While many Board members represent the yacht design and manufacturing industry, Carolina recognized that more representation was needed from the marine services side –she now fills that gap.

With her knowledge of the business, she has been able to help identify areas of superyacht service that require improvement, including reducing the number of boxes and plastic containers used to transport items to and from superyacht vessels and trainings for captains and crew on how to use onboard generators more efficiently.

Carolina’s contributions were included in WRF’s recent “Three-Year Plan,” which notably includes an educational program aimed specifically at marina sustainability.

Carolina feels that Safe Harbor has made her involvement with WRF possible.

“Safe Harbor has been so supportive of me, but I think Safe Harbor is supportive in general. I am so excited about our corporate commitments to the environment. “

In addition to Carolina’s continued involvement with WRF, she attended the Monaco Yacht Show in fall 2022. Of particular interest was the Sustainability Forum, which showcased a variety of different vendors operating at the

Safe Harbor Puerto Del Rey

intersection of yachting and sustainability. WRF team members were responsible for vetting vendors to ensure their products actually met the criteria necessary for the Sustainability Forum.

While in Monaco, Carolina was also able to meet WRF team and Board members in person and engage in conversations about marina sustainability assessments and the roll out of the Yacht Environmental Transparency Index ("YETI"), a revolutionary scoring tool used to rate and compare the sustainability performance of yachts.

Seeing how the Superyacht Industry is interested in sustainable solutions and developments was motivating... It makes me proud to work for a company that is addressing it as well.

“The Monaco Yacht Show was an unforgettable experience,” said Carolina. “Seeing how the Superyacht Industry is interested in sustainable solutions and developments was motivating. Not only vendors, vessels, and suppliers, but even the European governments are playing a part in addressing sustainability. It makes me proud to work for a company that is addressing it as well.”

At Safe Harbor, caring for our people and the natural environment we operate in is integral to the success of our business. Despite the economic headwinds we faced in 2022 and early 2023, our commitment to sustainable growth is unwavering.

Similarly, our mindset is one of constant improvement.

In 2023, we aim to ensure that our strategic Framework remains aligned with key stakeholder preferences and business priorities. In addition to striving toward the goals laid out in this report, we will work toward addressing gaps in our reporting and actionable concerns raised through our Teammate Engagement process.
