About Investor

Alpha G Investment Management (formerly Teton Advisors) underwent significant restructuring in 2025, including reincorporation from Delaware to Wyoming and the strategic sale of Keeley Teton Advisors assets to GAMCO Investors for proceeds of at least $11.5 million. The firm now operates as a focused smaller-company investment manager with $292 million in assets under management as of September 30, 2025, down from a peak of $2.7 billion in 2019. The company manages four mutual funds following the asset sale: TETON Westwood Mighty Mites Fund, TETON Westwood Balanced Fund, TETON Convertible Securities Fund, and TETON Westwood Equity Fund. Founded in 1994 and headquartered in Greenwich, Connecticut, the firm operates through two registered investment advisor subsidiaries and maintains strong cash reserves of $30.3 million. The Board has approved up to $1.5 million for development of new alternative investment products including hedge funds, venture capital funds, and exchange-traded products as part of its strategic repositioning. The company trades on OTCQX under ticker TETAA with high insider ownership and a current book value per share of $21.55.
