American Stock Transfer & Trust Company

American Stock Transfer & Trust Company, now branded as EQ, is a transfer agent and shareholder services provider headquartered in the United States. The firm was originally founded to handle stock transfer and registration, and today serves corporate issuers, equity plan sponsors, and individual shareholders. EQ's core business is administering the ownership records of public and private companies. EQ offers a suite of platforms, including a Cap Table Management product, an Ownership Intelligence platform, a corporate and mutual fund proxy campaign tool, and a lost asset recovery service. These tools serve clients across corporate actions, shareholder communications, and data reconciliation. The firm emphasizes responsible business practices—collaboration, equity, and sustainability—as part of its operational ethos. The company's website provides separate portals for individuals, corporate clients, and brokers/attorneys, indicating a multi-stakeholder service model. No named principals, team size, AUM, or recent material events are disclosed on the public site. The firm appears to focus on infrastructure and administration, not asset management or investment. EQ's structural differentiator is its focus on transfer agency and shareholder data management, a niche distinct from investment management. This positions the firm as a technology-enabled services provider for corporate governance and equity administration, rather than a capital allocator.
