The RBB Fund, Inc. (RBB) operates as the oldest and largest independent multiple series trust, providing a turnkey platform for exchange-traded funds (ETFs) and mutual funds that enables investment advisers to focus on asset management while RBB handles establishment, servicing, and corporate governance; the firm oversees approximately $28 billion in assets across over 70 offerings from 12 investment advisers and more than 20 unaffiliated sub-advisors. Founded in 1988 and headquartered in Wilmington, Delaware, RBB supports a diverse range of passively and actively managed funds targeting fixed income, equity, and alternative strategies for institutional and retail investors primarily in the United States. Core products include specialized U.S. Treasury ETFs such as the US Treasury 7 Year Note ETF (USVN; launched March 2023; tracks the Bloomberg US Treasury Bellwethers 7-Year Total Return Index), alongside the US Treasury 30 Year Bond ETF (UTHY), 10 Year Bond ETF, 5 Year Bond ETF, 3 Year Bond ETF, and 1 Year Treasury Bill ETF; additional offerings encompass equity-focused mutual funds and ETFs like the F/m Investments Large Cap Focused Fund, Adara Smaller Companies Fund, and active strategies in sectors including life sciences, special situations, and thematic investments such as EV materials futures. In recent developments, RBB has accelerated its ETF platform growth through strategic partnerships, including launches with First Eagle Investments (two active ETFs in late 2024), Emerald Advisers and F/m Investments (F/m Emerald Life Sciences Innovation ETF in October 2024 and F/m Emerald Special Situations ETF or SPIT), and Tweedy, Browne's entry into ETFs; the platform expanded from $18.5 billion to $28 billion in assets within two years, driven by ETF demand, conversions, and semi-transparent models amid regulatory shifts like proposed multi-share class structures. RBB continues to prioritize scalability, cost efficiencies, and innovative adviser onboarding, positioning it for further U.S. market expansion and potential international growth.
