The Fund uses a “passive” or indexing approach to try to achieve the Fund’s investment objective. Unlike many investment companies, the Fund does not try to “beat” the Index and does not seek temporary defensive positions when markets decline or appear overvalued. The Fund generally expects to use a replication strategy. A replication strategy is an indexing strategy that involves investing in the securities of the Index in approximately the same proportions as in the Index. However, the Fund may utilize a representative sampling strategy with respect to the Index when a replication strategy might be detrimental to shareholders, such as when there are practical difficulties or substantial costs involved in compiling a portfolio of equity securities to follow the Index, in instances in which a security in the Index becomes temporarily illiquid, unavailable or less liquid, or as a result of legal restrictions or limitations (such as tax diversification requirements) that apply to the Fund but not the Index.

Under normal circumstances, the Fund will invest at least 80% of its net assets (plus borrowings for investment purposes) in the securities of companies that comprise the Index. In pursuing this investment strategy, the Fund invests 80% of its net assets in companies actively involved in providing cyber security technology and services, in accordance with the ISE Cyber Security® Industry classification. The Index will consist of a selection of constituents in the Nasdaq ISE Cyber Security Index (the “Parent Index”).

The Parent Index tracks the performance of the common stock (or corresponding American Depositary Receipts (“ADRs”) or Global Depositary Receipts (“GDRs”)) of companies (i) that are a direct service provider (hardware/software developer) for cyber security and for which cyber security business activities are a key driver of the business (“Infrastructure Providers”) or (ii) whose business

model is defined by its role in providing cyber security services and for which cyber security business activities are a key driver of the business (“Service Providers”, and collectively with “Infrastructure Providers,” the “Cyber Security Companies”). Cyber security refers to products (hardware/software) and services designed to protect computer hardware, software, networks and data from unauthorized access, vulnerabilities, attacks and other security breaches. The securities of each company in the Index must also be listed on a securities exchange. The categories of Infrastructure Providers and Service Providers are referred to herein as “sectors”.

To be included in the Index, companies from the Parent Index must derive at least 90% of their revenues from cyber security and must have a Revenue Contribution score of at least 1.25%. The Revenue Contribution Score is the product of a company’s market capitalization and the percentage of a company’s revenue derived from cyber security or cyber security-related activities. The Revenue Contribution Score is derived from the Parent Index prior to applying any additional eligibility screens. Eligible constituents are screened for investability (e.g., must not be listed on an exchange in a country which employs certain restrictions on foreign capital investment), a minimum market capitalization of US$1billion, a free-float equivalent to at least 20% of shares outstanding, and a minimum three-month average daily dollar trading volume of US$1million.

The Index has a quarterly review in March, June, September, and December of each year at which times the Index is reconstituted and rebalanced by Nasdaq, Inc. (the “Index Provider”). Component changes are made effective after the market close on the third Friday of March, June, September, and December.

The Index is owned, calculated, and maintained by the Index Provider, which is independent of the Fund, Amplify Investments LLC, the Fund’s investment adviser (the “Adviser” or “Amplify Investments”), and Penserra Capital Management (“Penserra” or the “Sub-Adviser”). The Index Provider may make adjustments to the constituents or their weights in the Index in between scheduled rebalances and reconstitutions of the Index as the Index Provider deems appropriate to ensure the integrity of the Index.

As of September30, 2025, the Index was comprised of 26 constituents and had significant exposure to the information technology sector.

The Fund rebalances its portfolio in accordance with its Index, and, therefore, any changes to the Index’s rebalance schedule will result in corresponding changes to the Fund’s rebalance schedule.

Concentration Policy. The Fund will not concentrate its investments (i.e., invest more than 25% of the value of its total assets) in securities of issuers in any one industry or group of industries, except to the extent that the Index concentrates in an industry or group of industries. As of the date of this prospectus, the Index is concentrated in the software industry.

Diversification Status. The Fund is classified as a “non-diversified company” under the Investment Company Act of 1940, as amended (the “1940 Act”).
