ROBY Investment Objective and Strategy

YieldMax® RoboTech & Automation Portfolio Option Income ETF describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Tidal Trust II.

Investment objective

The Funds primary investment objective is to seek current income.

Principal investment strategy

The Fund is an actively managed exchange-traded fund (ETF) that seeks defined income (i.e., a set annual income target as discussed below) and capital appreciation. The Funds strategy involves: (1) constructing a portfolio of U.S.-listed equity securities of RoboTech & Automation Companies (each, an Underlying Security) (the Equity Strategy); and (2) generating income through an options portfolio (the Options Strategies), which involve using options contracts on Underlying Securities and/or RoboTech & Automation ETFs (described below). Additionally, the Fund will maintain a minor allocation to cash, money market funds or U.S. Treasuries, not exceeding ten percent of its total assets. Equity Strategy Tidal Investments LLC (the Adviser) selects RoboTech & Automation Companies in which the Fund will invest.

RoboTech & Automation Companies are companies engaged in the following: ? Hardware & Components Companies : Companies that design, manufacture, or supply semiconductors, sensors, electrical/mechanical equipment, actuators, and precision instruments that are primarily used in, or integral to, robotics systems and industrial or service automation applications. ? Systems & Integration Companies : Companies that develop, produce, or integrate industrial machinery, factory automation, robotics integrators, autonomous mobility systems, and logistics/warehouse automation. ? Software & Control Companies : Companies that develop, provide, or enable automation control software, robotics operating systems, computer vision, AI/perception tools, and electronic instrumentation supporting automated processes.

To enable the Fund to effectively implement its Options Strategies, the Adviser evaluates the liquidity of a potential companys common stock and the liquidity of its options contracts. The Fund is generally unconstrained, meaning it may invest in companies of any market capitalization size. The Adviser will also evaluate price level and implied volatility (i.e., a measure of how much the market believes the price of a stock or other underlying asset will move in the future) when selecting companies for investment and will monitor for these factors when determining whether to select new companies or remove existing companies from the portfolio. RoboTech & Automation Companies may include companies from foreign countries, including emerging markets. The Underlying Securities may include such companies U.S.-listed depositary receipts, such as American Depositary Receipts (ADRs) and Global Depositary Receipts (GDRs).

The Fund will be concentrated in the same industry or industries as those of the RoboTech & Automation Companies, which subjects the Fund to specific industry-related risks. The Funds portfolio will generally be comprised of between fifteen and fifty companies. Dividends, if any, paid by the Funds portfolio holdings will contribute to the Funds income generation. The Fund will, under normal circumstances, invest in Underlying Securities directly. However, from time to time, the Fund may invest in Underlying Securities synthetically for tactical reasons or to comply with regulatory requirements. To invest synthetically, the Fund will use options contracts on Underlying Securities (considered indirect or synthetic long holdings of the Underlying Securities) to gain exposure to the share price performance of the Underlying Securities.

Options Strategies Seeking Premiums Separately, the Fund employs various options strategies on some or all of the Underlying Securities focused on generating premiums. Also, depending on the Advisers assessment of one or more of the Underlying Securities options contracts (e.g., they are insufficiently liquid or too costly), the Fund may employ options strategies using options on a RoboTech & Automation ETF (i.e., a passively-managed, U.S.-listed ETF that seeks to track the performance of a RoboTech & Automation Index (described below)). Generally speaking, the Fund sells (writes) options on some or all of the Underlying Securities, receiving premiums from counterparties that pay for the right to buy or sell at a set price. These premiums are an important driver of the Funds distributions.

On a periodic basis, generally weekly to monthly (but subject to market conditions), the Adviser uses one or more options strategies to seek to generate net premiums (i.e., option premiums received, less option premiums paid). Receipt of an option premium does not always represent income; depending on the outcome of the overall options transaction. Premium levels are influenced by market conditions, particularly volatility, and the Adviser may adjust the Funds options strategies depending on the outlook for the Underlying Securities. While option selling may provide premium opportunities, it may also limit upside gains or increase downside risk. The options strategy most frequently utilized by the Fund is called a covered call spread, which is a type of selling credit spread. The Fund uses covered call spreads to earn premium by selling a call option while buying another at a higher strike, with both profit and loss capped.

See the prospectus section titled Additional Information About the Funds for a list of the options strategies that the Fund may utilize, together with a description of each options strategy. Treasuries In addition, the Fund will hold cash or short-term U.S. Treasury securities. These securities serve a dual purpose: providing collateral for the Options Strategies and contributing to the Funds income generation. Additional Fund Attributes The Fund is classified as non-diversified under the 1940 Act. The Funds investment strategy is expected to result in high portfolio turnover on an annual basis. Under normal circumstances, the Fund will invest at least 80% of the value of its assets, plus borrowings for investment purposes, in the equity securities of RoboTech & Automation Companies and in options contracts on RoboTech & Automation Companies and RoboTech & Automation ETFs.

For purposes of the foregoing, the Fund defines a RoboTech & Automation Company as a company that derives 50% or more of its revenue in one or more of the following themes: (i) Hardware & Components semiconductors, sensors, electrical/mechanical equipment, actuators, and precision instruments, (ii) Systems & Integration industrial machinery, factory automation, robotics integrators, autonomous mobility systems, and logistics/warehouse automation, (iii) Software & Control automation control software, robotics operating systems, computer vision, AI/perception tools, and electronic instrumentation supporting automated processes. The Fund defines a RoboTech & Automation ETF as a US-listed ETF that seeks to track the performance of a RoboTech & Automation Strategy or Index.

Lastly, the Fund defines a RoboTech & Automation Strategy or Index as a strategy or benchmark that invests in a selection of stocks from companies operating in any of the RoboTech & Automation sectors. The Fund will seek to provide weekly cash distributions. Distributions may include a significant portion classified as return of capital (ROC). ROC generally represents a return of a shareholders invested capital rather than traditional income such as dividends or interest. See the prospectus section titled Additional Information About the Funds for more information about option premiums and ROC. There is no guarantee that the Funds investment strategy will be properly implemented, and an investor may lose some or all of its investment.
