DEAR FRIENDS, In a socially distant world in which devices offer instanta- neous information and constant distraction, Rockland Trust remains committed to developing personal relationships with our colleagues, customers, and the communities we serve. We firmly believe that relationship banking, built upon a foundation of care and respect, is more important now than ever because it connects us to each other and brings deeper meaning to our work. Throughout 2021, we found meaning by supporting our colleagues, serving and advocating for our customers, and strengthening our communities. We remain inspired by our vision to be the Bank Where Each Relationship Matters®—a purpose that has unleashed energy, fueled a desire to excel, and led to a year of incredible achievements and record results. In 2021, we announced and successfully completed our largest acquisition to date, welcoming over 300 colleagues and more than 65,000 customer households from East Boston Savings Bank. Within 48 hours of the closing, our remarkable team accomplished a systems and account conversion, transformed our new branches, and established the network infrastructure for our new colleagues. The com- bination of our two institutions increased Rockland Trust’s presence in new communities throughout Greater Boston with 26 traditional branches, our first ever mobile branch, and 41 additional automated teller machines. When we set out to unite our two community banks, we believed that our shared set of values made us the right fit. This belief was upheld by the rich bonds that have formed between colleagues from both organizations. These connections were made during a busy transition and were grounded in trust, patience, and an openness to learn from one another. With the addition of our new East Boston Savings Bank colleagues and footprint, we are a stronger, more diverse organization, serving more diverse customers and communities than ever before. We look forward to deepening our relationships with the families, businesses, and neighborhoods we now have the honor of supporting for many years to come. Bolstered by the acquisition of East Boston Savings Bank, we reached record levels of growth year-over-year across our CHRISTOPHER ODDLEIFSON CEO, INDEPENDENT BANK CORP. & ROCKLAND TRUST balance sheet and ended the year with: • $20.4 billion in assets, up 55% from $13.2 billion • $13.6 billion in total loans, up 45% from $9.4 billion • $16.9 billion in deposits, up 54% from $11 billion • A tangible book value of $42.25, up $6.66 or 19% driven by the immediate positive impact of the East Boston Savings Bank acquisition In addition to all of the effort and planning related to the East Boston Savings Bank acquisition, we remained steadfast in focusing on our core community banking strategies, as evidenced by the following record accomplishments: • Originating nearly $2 billion in commercial loans and small business loans, excluding Paycheck Protection Program loans • Closing over $1 billion in residential mortgages and over $400 million in home equity • Generating $671 million in Investment Management Group new business volume, bringing our assets under administration to roughly $5.7 billion • Opening record levels of new consumer checking accounts, resulting in organic core deposit growth of $2.7 billion The combination of all these achievements led to an adjusted operating net income of $187.6 million in 2021, an increase of 54% versus $121.7 million in the prior year, while return on average assets on an adjusted operating basis increased by 30% to 1.26%. Additionally, loan delinquency and nonperforming assets levels remained low, resulting in minimal net charge-off activity, which as a percent of average loans totaled only 0.01% for the year. The successful acquisition and execution of our strategic priorities that made these financial results possible was the result of thousands of hours of work, late nights, early morn- ings, and considerable effort from nearly every department across the Bank. And all the while, impressive progress was being made on many other important initiatives.

KAREN REBAZA VP, COMMUNITY DEVELOPMENT OFFICER YOURBANKERSM OUR VIRTUAL CUSTOMER ASSISTANCE TOOL INDEPENDENT BANK CORP. | 2021 ANNUAL REPORT 5 In 2021, we also advanced our Diversity, Equity, and Inclu- sion (DEI) journey. We enhanced our diversity dashboard and our colleague sourcing, development, and retention efforts. We also provided DEI education, training, and awareness programming, tracked DEI information in our charitable giving, further developed our supplier diversity program, and implemented marketplace strate- gies. A highlight of these efforts was the launch of a new development program to help professionals of color make progress toward their career aspirations. Another signifi- cant milestone was the Racial Equity Grant Program offered through our affiliated charitable foundations, through which 45 local nonprofits received funding to advance racial equity within their organizations and communities. At the heart of our DEI mission is the need to develop and sustain an inclusive workplace where all colleagues have the ability and opportunity to succeed. Our colleagues’ commitment to making Rockland Trust a great place to work and a great place to bank was once again hailed by third parties. For the 13th year in a row we were named a "Top Place to Work" by The Boston Globe, and for the 7th consecutive year, we were rated by the Human Rights Campaign Foundation as one of the "Best Places to Work for LGBTQ Equality." In addition to our work- place awards, we were recognized for achieving exception- ally high satisfaction ratings for both retail and commercial banking, and we were once again rated the "#1 Bank in Massachusetts" according to Forbes World’s Best Banks list. I am extremely proud of the people I work with every day, who consistently go above and beyond to serve one another, our customers, and our communities with zeal and compassion. At Rockland Trust, we have a long history of creating an environment of highly engaged employees who produce consistently strong performance. I’ve discussed our Cycle of Engagement in previous letters and the important role it plays: engaged employees provide exemplary service to our customers, who reward us with more business, which enables us to reinvest in our colleagues, customers, and communities. This cycle doesn’t just happen; it is formed, nurtured, cultivated, and fed by our healthy culture. 6 INDEPENDENT BANK CORP. | 2021 ANNUAL REPORT ENGAGED EMPLOYEES PROVIDE EXEMPLARY SERVICE TO OUR CUSTOMERS, WHO REWARD US WITH MORE BUSINESS, WHICH ENABLES US TO REINVEST IN OUR COLLEAGUES, CUSTOMERS, AND COMMUNITIES. “This cycle doesn’t just happen; it is formed, nurtured, cultivated, and fed by our healthy culture.” Where Each Relationship Matters® There are many programs that contribute to our award-winning culture, including employee resource groups, comprehensive training programs, leadership development programs, employee recognition programs, and an attractive benefits package. What I find interesting is that while many companies, particularly large ones with nearly unlimited resources, have the same offerings and more, they do not have Rockland Trust’s reputation of being a great place to work. So why is Rockland Trust special? The answer transcends programs or desirable benefits. The fact is, every one of my colleagues makes a very personal decision to bring their most caring and respectful selves to work every day. Our customers often tell me about the collegial welcoming atmosphere they observe at Rockland Trust. This type of dedication can’t be easily replicated and is only possible because of the underlying foundation of safety and trust we’ve worked so hard to create. This environment of safety and trust leads to connected relationships between leaders and colleagues. When colleagues believe their leaders have their best interests at heart, they are more likely to work to their full potential. With the support of their managers, our colleagues look for opportunities to innovate and share new and honest perspectives, which result in productive discussions and more thoughtful decision-making. This empowerment instills positive feelings about our workplace and leads to individuals, at all levels of our organization, taking personal accountability for our shared purpose of making each relationship matter. “The fact is, every one of my colleagues makes a very personal decision to bring their most caring and respectful selves to work every day.” LIVING OUT OUR PROMISES OUR STOUGHTON BRANCH THANKING FIRST RESPONDERS WHO WORKED OVERTIME TO KEEP THE COMMUNITY SAFE LIVING OUT OUR PROMISES OUR ROCKLAND TRUST PAN-MASS CHALLENGE TEAM RAISED OVER $370K FOR DANA-FARBER AND THE JIMMY FUND INDEPENDENT BANK CORP. | 2021 ANNUAL REPORT 7 Toward the end of 2021, I asked some of my colleagues to reflect on what this purpose means to them. Here are a few examples of what I heard: “Where Each Relationship Matters® means exceeding customer expectations by delivering superior service and meeting the unique needs of the many communities we serve. Each of our markets is different, and our ability to understand those needs helps us gain the confidence of new customers and build on our existing relationships.” - JIM SMITH RETAIL BANKING “If we do the right thing, the rest will follow. We are empowered at Rockland Trust to spend time with customers that need our help regardless if a sales opportunity exists or not. We all have an opportunity to impact someone’s day in a positive way by doing the right thing for them and making them feel important.” - CHARLIE GRAY BUSINESS BANKING “Since hearing of the merger, I was wondering if my purpose with Rockland Trust would be the same as it was with East Boston Savings Bank. I’ve realized my purpose to serve my customers to the best of my ability and volunteer in my community is the same. The only thing that has changed is the name on my building.” - FELICIA PUOPOLO RETAIL BANKING 8 INDEPENDENT BANK CORP. | 2021 ANNUAL REPORT “Everyone genuinely wants to help one another. True, long-lasting friendships are forged here, unlike any place I’ve ever worked, and I am so proud to be a member of the Rockland Trust team.” - SUSAN DAILEADER INVESTMENT MANAGEMENT GROUP “The Rockland Trust culture embraces individuality, strength, and collaboration. It’s an environment that begins and is sustained by remarkable leadership. I am honored and proud to be a member of the Rockland Trust team.” - ROSE BUCKLEY COMMERCIAL LENDING As I reflect on the past year, I am filled with pride and gratitude for my colleagues who powered through many challenges with poise and determination. We are thrilled to have welcomed three new Rockland Trust board members: Warren Fields, James O’Shanna Morton, and Susan Perry O’Day, each of whom has brought unique talent, insight, and experience. As I look back on 2021, it has never been clearer to me that organizations don’t endure hardship, people do. We emerged from 2021, thankful for each other and stronger than ever in our steadfast pursuit of being the Bank and workplace Where Each Relationship Matters®. I am tremendously grateful for the trust and loyalty our customers and shareholders continue to place in me and Rockland Trust as we look forward to another successful year!
