Atlantic Management Company

What Atlantic Management Company does

Atlantic Management Company, Inc. is a privately held, nationally recognized valuation and transaction advisory firm founded in 1968 and headquartered at One New Hampshire Avenue, Suite 125, Portsmouth, NH. The firm operates with approximately 10 team members organized around four integrated service lines: Valuation Services (business valuations, fairness opinions, and solvency opinions), ESOP Services (planning, formation, annual administration, and strategic alternatives such as dividend recapitalization and terminations), Merger & Acquisition Services (seller and buyer representation, and strategic corporate finance advice), and Ownership Transition Services (succession planning, generational transfers, and management buyouts). Its core technology consists of professional valuation methodologies executed in accordance with American Society of Appraisers, Institute of Business Appraisers, NACVA, AICPA, and USPAP standards, with credibility supported by professional credentials held across the staff (ASA, CVA, ABV, MCBA, CBA, CPA, CGMA).

The firm serves a primarily enterprise client base including companies exploring or pursuing employee ownership through ESOPs, ESOP fiduciaries and trustees, business owners and corporate executives needing valuation opinions for tax, financial reporting, and litigation purposes, and parties to M&A and ownership-transition transactions. Revenue is generated through professional advisory fees on engagement-based work — including initial assessments, feasibility studies, valuations, fairness opinions, solvency opinions, transaction structuring, and ongoing administration services — under a quote-based pricing model. There is no public pricing, no disclosed revenue, and no technology product or SaaS component; the offering is pure professional services.

Go-to-market is relationship- and community-led, relying on direct engagement through established networks of attorneys, accountants, ESOP trustees, third-party administrators, and bankers, supplemented by active speaking and panel participation at national and regional ESOP conferences and staff support for The ESOP Association (national and New England chapter), NCEO, and the Vermont Employee Ownership Center. As of November 3, 2025, the firm is being acquired by Chartwell to expand Chartwell's Northeast presence and enhance its ESOP advisory platform, signaling a pending structural change in ownership rather than an organic shift in the firm's service model.
