Investment objective & strategy

As of Jan. 5, 2026 · prospectus

Objective. The investment objective of the F/m Ultrashort Treasury Inflation-Protected Security (TIPS) ETF (the F/m Ultrashort TIPS Fund or the Fund) is to seek investment results that correspond (before fees and expenses) generally to the price and yield performance of the Bloomberg U.S. Ultrashort TIPS 1-13 Months Total Return Unhedged USD Index (I39232US).

Strategy. The Fund is a passively-managed exchange-traded fund (ETF) that seeks investment results, before fees and expenses, that correspond generally to the price and yield performance of the Bloomberg U.S. Ultrashort TIPS 1-13 Months Total Return Unhedged USD Index (I39232US) (the Underlying Index), which measures the performance of U.S. Treasury Inflation-Protected Securities (TIPS) with maturities from 1 month up to (but not including) 13 months. TIPS are income-generating instruments whose interest and principal payments are adjusted for inflation. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, the non-seasonally adjusted Consumer Price Index for All Urban Consumers (CPI-U), and TIPS principal payments are adjusted according to changes in the CPI-U.

TIPS are income-generating instruments whose interest and principal payments are adjusted for inflation. The inflation adjustment, which is typically applied monthly to the principal of the bond, follows a designated inflation index, the non-seasonally adjusted Consumer Price Index for All Urban Consumers (CPI-U), and TIPS principal payments are adjusted according to changes in the CPI-U. A fixed coupon rate is applied to the inflation-adjusted principal so that, as inflation rises, both the principal value and the interest payments increase. This can provide a hedge against inflation, as it helps preserve the purchasing power of an investment. Because of this inflation adjustment feature, inflation-protected bonds typically have lower yields than conventional fixed-rate bonds. Under normal market conditions, F/m Investments LLC (the Adviser) seeks to achieve the Funds investment objective by investing at least 80% of the Funds net assets (plus any borrowings for investment purposes) in TIPS with maturities of 1-13 months. bonds typically have lower yields than conventional fixed-rate bonds. Under normal market conditions, F/m Investments LLC (the Adviser) seeks to achieve the Funds investment objective by investing at least 80% of the Funds net assets (plus any borrowings for investment purposes) in TIPS with maturities of 1-13 months. The Adviser uses a representative sampling indexing strategy in seeking to achieve the Funds investment objective. Under normal market conditions, the Fund invests substantially all of its assets in the securities comprising the Underlying Index and in securities that the Adviser determines to have economic characteristics that are substantially identical to the economic characteristics of the securities that comprise the Underlying Index, including, but not limited to, bonds that are capital-indexed and linked to a commonly used domestic inflation index. In seeking to track the Underlying Index, the Fund may invest in securities that are not included in the Underlying Index, cash and cash equivalents and/or money market instruments, such as repurchase agreements and money market funds. The Fund is non-diversified, which means it may invest a greater percentage of its assets in the securities of a single issuer than a diversified fund. The Underlying Index The Underlying Index was incepted in January 2025, with history back to January 1, 2015, by Bloomberg Finance LP (the Index Provider). The Underlying Index is composed of equally weighted sub-components that have a remaining maturity from one (1) month up to (but not including) thirteen (13) months ( e.g. , 1-2 month maturities, 2-3 maturities, etc.). Federal Reserve holdings of TIPS are excluded from the face amount outstanding of each bond in the Underlying Index. The Underlying Index has a minimum liquidity requirement of $500M USD par amount outstanding (not adjusted for index duration). The bonds included in the Underlying Index are capital-indexed and linked to a commonly used domestic inflation index. Principal and interest are inflation-linked and denominated in U.S. dollars. The bonds are rated investment grade (Baa3/BBB-/BBB- or higher) using the middle rating of Moodys Investors Service, Inc.(Moodys), Fitch Ratings, Inc. (Fitch) and Standard & Poors Financial Services LLC (S&P); when a rating from only two agencies is available, the lower is used; when only one agency rates a bond, that rating is used. In cases where explicit bond level ratings are not available, the Index Provider may use other sources to classify securities by credit quality. The Underlying Index is rebalanced by the Index Provider on the last business day of each month. The Underlying Index is calculated and administered by the Index Provider, which is not affiliated with the Fund or the Adviser. The Index Provider calculates the Underlying Index and Parent Index on a total return basis. Additional information regarding the Underlying Index, including its value, is available at https://assets.bbhub.io/professional/sites/27/Bloomberg-US-Ultrashort-TIPS-1-13-Months-Index.pdf. The Fund may invest in securities of other affiliated and unaffiliated ETFs registered under the Investment Company Act of 1940, as amended, that invest primarily in Fund eligible investments (collectively, Underlying Funds) to the extent permitted by applicable law and subject to certain restrictions. The Fund may also seek to increase its income by lending securities. These loans will be secured by collateral (consisting of cash, U.S. government securities, or irrevocable letters of credit) maintained in an amount equal to at least 100% of the market value, determined daily, of the loaned securities. Cash collateral received by the Fund in connection with its lending of portfolio securities will be invested in short-term investments, including money market funds. The Fund has elected to qualify each year for treatment as a regulated investment company (RIC) under Subchapter M of Subtitle A, Chapter 1, of the Internal Revenue Code of 1986, as amended (the Code).
