Abacus Achieves Recognition on the 2026 Inc. 5000 List

Abacus, a global managed IT and cybersecurity service provider, proudly announces that it has been ranked No. 1,568 on the prestigious 2026 Inc. 5000 list, which showcases America's fastest-growing private companies. This accolade is particularly significant as it marks the fifth year that Abacus has received this honor, reflecting the company’s sustained growth and resilience in a competitive landscape.

The Inc. 5000 list is determined by the percentage revenue growth of private companies over a three-year period, specifically from 2022 to 2025 in this case. For Abacus, this recognition is not merely the result of a single successful year, but rather a testament to years of consistent performance and strategic execution.

Anthony J. D’Ambrosi, the CEO of Abacus, expressed his pride regarding the company's achievement, stating, "Getting on the Inc. 5000 list for the fifth time means a lot to all of us at Abacus. It’s a reflection of our team's dedication to providing exceptional services to our clients. Our ethos of being 'Always Ahead' drives us to navigate challenges in our industry into opportunities for innovation and value delivery. This recognition encourages us to continue investing in the advanced technologies that are vital for our clients’ success."

In addition to its overall ranking, Abacus earned a remarkable position of No. 144 in the New York-Newark-Jersey City metro area, and was also featured at No. 126 among all honorees based in New York. In the context of IT Services companies, Abacus achieved the No. 66 ranking nationwide, further solidifying its standing as a leading force in the managed services domain.

Abacus specializes in providing IT and cybersecurity solutions tailored to meet the stringent needs of highly regulated industries such as financial services and healthcare. The firm has experienced significant growth in the past two years, largely attributed to strategic mergers and acquisitions. Notable moves include the acquisition of Entara, a prominent managed service provider with incident response capabilities, and a merger with Medicus IT, which has enhanced Abacus' offering in healthcare services.

As part of its continuous evolution, Abacus has diversified its service offerings to include AI orchestration, cybersecurity governance, emergency incident response, and advisory services. This expansion is indicative of the company’s commitment to evolving alongside technological advancements and client needs.
