TO OURSTOCKHOLDERS
Dear Stockholders,
We are proud to share Mack-Cali’s inaugural Corporate Responsibility Report to provide you with a better understanding of what we put into practice every day: care, respect, and responsible
stewardship for our properties, our people, and our community. We are a real estate company with a business focus on generating revenues from physical assets. However, we recognize and value
all the individuals that make our business thrive every day – our customers, our residents, our employees, and the members of the communities we serve. It is our sensitivity and respect for the
ecosystems in which we operate that provided the impetus for Mack-Cali to be an early adopter of sustainability standards, as we established a Corporate Energy Group focused on energy
consumption and efficient buildings long before “ESG” became a focal point of the investment community.
Beyond the bricks and mortar, we are an active player in trying to reduce carbon emissions by providing ride sharing subsidies to tenants and residents from our communities to mass transit
nodes. We championed and subsidized the establishment of a ferry service at our Harborside property to augment mass transit options for the workers and residents of Jersey City. Many of our
properties feature electric car charging stations and bike sharing options. Our activities also extend to fostering a feeling of community in both our office and residential properties by programming
wellness events and social gatherings, such as concerts and food fairs, that knit our properties closer to the towns and cities in which we operate.
Diversity thrives at Mack-Cali spanning race, gender, ethnicity, age, physical ability, and experience, as sixty percent of our employees have been with the company for longer than five years. We
are proud of these metrics and attribute our retention longevity to some of the programs we extend to our associates, including continuous training and development, tuition assistance, and an
enhanced safety net in the event of unforeseen health issues. We care about our people and our communities.
With respect to corporate philanthropy, we specifically channel our contributions to charities, learning institutions, art, and cultural centers. Our contributions go beyond financial support, as many
of our associates and senior management are actively engaged in volunteering their time to sustain the vibrancy of our communities. Our spirit of service and stewardship extends to our
governance, where we have made meaningful strides to ensure that all our stakeholders have a voice and that their concerns are recognized and considered.
Sustainability is a journey. We are excited to embrace the sustainability challenge to ensure the success of Mack-Cali for years to come.
Sincerely,
