Tidal Trust II – Defiance Daily Target 2X Long AMPX ETF is a non-diversified, actively managed exchange-traded fund that seeks to provide daily investment results, before fees and expenses, equal to 200% of the daily percentage change in the share price of Amprius Technologies, Inc. (NYSE: AMPX). The Fund provides leveraged long exposure to AMPX through derivative instruments, including swap agreements and listed options contracts, rather than direct investment solely in the underlying issuer’s common stock. Its offerings consist of a single-stock leveraged ETF designed for active and tactical investors seeking short-term bullish exposure to Amprius Technologies, a developer and manufacturer of high-performance lithium-ion batteries based on proprietary silicon-anode technology for aviation, defense, drone, electric-vehicle and other electrification applications. The Fund’s objective applies to a single trading day only and is not intended to track twice the cumulative return of AMPX over periods longer than one day; returns over longer holding periods may differ materially from the stated daily target as a result of daily rebalancing, volatility and compounding. The Fund is sponsored by Defiance ETFs LLC and advised by Tidal Investments LLC, operates in the U.S. exchange-traded-products market, is domiciled in the United States, and is listed for trading under the ticker symbol AMPU. AMPU was formed and commenced operations on May 5, 2026. Its principal customer base comprises U.S. investors, traders and financial-market participants seeking exchange-traded, margin-free access to leveraged daily exposure to Amprius Technologies shares. The Fund’s principal recent strategic development is its May 2026 launch by Defiance ETFs as the first daily 2x long ETF focused on Amprius Technologies, expanding Defiance ETFs’ lineup of single-stock leveraged products and providing a specialized vehicle for investors seeking amplified daily exposure to developments in advanced lithium-ion battery technology and related commercial and defense end markets.
