The RBB Fund, Inc. SGI U.S. Large Cap Core ETF

SGLC actively invests in US large-cap stocks, selected through business strengthening metrics and quantitative factors. The typical valuation metrics considered are earnings variability, debt, return on assets, competition customers, industry, leverage, volatility, price to book, and price to cash flow ratio. The fund may also invest in preferred stocks, warrants, convertibles, and ETFs. Additionally, the fund adviser performs an idiosyncratic risk assessment involving ESG ratings and returns potential in its investment decisions. SGLC is an actively managed, non-transparent fund that discloses its full holdings quarterly, with a 60-day lag. A proxy portfolio is published daily on its website as a substitute for the actual portfolio. While the fund discloses its actual portfolio holdings daily, it does not reveal the exact quantities or weightings. Investors should note that a non-transparent structure could result in wider spreads.
