BITA AI Inference Chip Select Index
The Index aims to capture the performance of global publicly listed securities issued by companies that are leaders in the development of artificial intelligence (“AI”) inference technologies. The Index constituents are primarily engaged in the design, fabrication, or integrated manufacturing of specialized chips, including GPUs, ASICs, and Neuromorphic processors, specifically optimized for the execution of AI models. Eligible constituents must demonstrate significant thematic exposure to the Index’s theme based on its total revenue derived from, or through its material involvement in, the following segments:
Inference GPUs: Companies that design or manufacture highly parallelized processing units. While originally for graphics, these chips are essential for AI inference due to their ability to handle the massive simultaneous mathematical throughput required by neural networks.
Custom AI ASICs: Companies focused on purpose-built silicon designed for a single, specific AI application. These chips are engineered from the ground up to provide maximum efficiency and performance for specific inference tasks, often outperforming general-purpose hardware.
FPGA-based AI Accelerators: Companies providing integrated circuits designed to be configured by a customer or a designer after manufacturing. In the AI context, these allow for hardware-level acceleration of inference algorithms that can be updated or re-programmed as AI models evolve.
AI-Optimized CPUs: Companies developing general-purpose processors with integrated AI acceleration capabilities, such as dedicated instructions, tensor-processing components, or neural processing engines. These processors support AI inference by
accelerating neural-network computations and performing the logical control, task orchestration, and sequential processing required to manage complex inference workloads.
Accelerator Modules: Companies that produce integrated hardware systems or plug-in boards that combine multiple AI chips, memory, and high-speed interconnects into a single unit designed to be deployed in high-performance data centers for massive-scale inference.
Neuromorphic Chips: Companies engaged in the development of brain-inspired computing hardware. These processors mimic the neuro-biological architectures of the human nervous system by using spiking neural networks, to achieve ultra-low power consumption, making them ideal for edge-device inference.
To provide an objective measure of the level of exposure of a company to a thematic segment, BITA GmbH, the Fund’s index provider (“Index Provider”) applies a proprietary scoring system to determine a company’s revenue-based exposure and material involvement. Revenue-based scoring is determined through an in-depth analysis of a company’s business footprint via the collection of publicly available data provided by the company in regulatory filings (such as annual reports, 10-Ks, 10-Qs, 20-Fs, 8-Ks), quarterly earnings reports, investor presentations, official earnings conference call transcripts, as well as credible news sources. A company’s material involvement is determined using the Index Provider’s evidence-based materiality scoring system that measures the company’s strategic importance to the Index theme, and assesses revenue exposure, disclosed investments, research & development activity, strategic partnerships, government contracts, or patent filings. The materiality score is weighted based on (i) strategic/market centrality (how central a company’s market position is within an index segment), (ii) enabling technology/IP criticality (whether a company holds technology or intellectual property (IP) that materially enables the index segment’s growth, independent of its own revenue from it), (iii) supply chain criticality/substitutability (how difficult it would be for the value chain to substitute the company if it exited), and (iv) ecosystem influence (whether the company shapes industry standards, partnerships, or platform dynamics beyond its own transactions).
Each Index constituent must (i) derive at least 50% of its total revenue from, or demonstrate material involvement in, at least one of the thematic segments listed above; (ii) be listed on one of the following exchanges: Australian Stock Exchange, Vienna Stock Exchange, Euronext Brussels, Canadian Securities Exchange, Toronto Stock Exchange, TSX Venture Exchange, Shanghai Stock Exchange, Shenzhen Stock Exchange, Nasdaq Copenhagen, Nasdaq Helsinki, Euronext Paris Exchange, Deutsche Börse, Hong Kong Stock Exchange, Euronext Irish Stock Exchange, Tel-Aviv Stock Exchange, Borsa Italiana, Tokyo Stock Exchange, Euronext Amsterdam Stock Exchange, New Zealand Stock Exchange, Euronext Oslo Børs, Euronext Lisbon, Singapore Exchange, Korea Exchange, Bolsas y Mercados Espanoles, Nasdaq Stockholm, SIX Swiss Exchange, Taiwan Stock Exchange, London Stock Exchange, Nasdaq, or New York Stock Exchange, (iii) have a market capitalization of at least $100 million; (iv) have a free-float percentage of at least 10%; and (v) have a 3-month average daily traded value of at least $1 million (“AI Chip Companies”).
The Index is rebalanced and reconstituted quarterly after the close of business on the third Friday of March, June, September, and December each year based on data as of the close of business of the first Friday of the rebalancing month. However, between quarterly rebalances, the Index Provider may, in accordance with the Index methodology, (i) add immediately, as Index constituents, initial public offerings (“IPOs”) or companies pivoting to activities related to an Index segment with a proven thematic exposure higher than the minimum requirement; and/or (ii) substitute an Index constituent or perform an extraordinary adjustment to the Index upon the occurrence of an extraordinary event as deemed by the Index Provider (e.g., a company files a shareholder report with the SEC that reflects at least 50% of the company’s total revenue from at least one of the segments listed above, or demonstrates material involvement in any of the segments listed above). In such cases, the Index Provider will announce the extraordinary Index adjustment with a notice period of at least two trading days (with respect to the affected constituent) and proceed to its implementation after the close of business on the effective date specified in the announcement.
As of June 19, 2026, the Index had 26 constituents, 12 of which were listed on a non-U.S. exchange. As of June 19, 2026, the Index had significant exposure to companies domiciled in the United States and Taiwan. The Index’s geographic exposure may change significantly with each reconstitution or based on market movements in between reconstitutions.
At the time of each rebalance and reconstitution of the Index, each constituent is weighted by its free-float market capitalization and cannot exceed 20% of the total Index weight. The cumulative weight of all constituents with a weighting of more than 4.5% cannot exceed 40% of the total weight of the Index. Excess weight is re-distributed proportionally among the uncapped constituents. Additionally, the weight of each Index constituent may rise and/or fall between Index rebalance dates.
The Index was established in 2026 and is owned by the Index Provider. The Fund’s Index Provider is not affiliated with the Fund’s adviser, sub-adviser, administrator, or distributor.
The Fund’s Investment Strategy
Under normal circumstances, at least 80% of the Fund’s net assets (plus borrowings for investment purposes) will be invested in AI Chip Companies, as defined above. The Fund’s investments in AI Chip Companies will primarily consist of equity securities (domestic and foreign) but may include total return swap agreements that provide exposure to AI Chip Companies.
The Fund will generally use a “replication” strategy to achieve its investment objective, meaning the Fund will generally invest in all of the component securities of the Index in the same approximate proportions as in the Index. However, the Fund may use a “representative sampling” strategy, meaning it may invest in a sample of the securities in the Index whose risk, return, and other characteristics closely resemble the risk, return, and other characteristics of the Index as a whole, when the Fund’s sub-adviser believes it is in the best interests of the Fund (e.g., when replicating the Index involves practical difficulties or substantial costs, an Index constituent becomes temporarily illiquid, unavailable, or less liquid, or as a result of legal restrictions or limitations that apply to the Fund but not to the Index).
The Fund generally may invest in securities or other investments not included in the Index, but which the Fund’s sub-adviser believes will help the Fund track the Index. For example, the Fund may invest in securities that are not components of the Index to reflect various corporate actions and other changes to the Index (such as reconstitutions, additions, and deletions).
The Fund may invest in: (i) U.S. Government securities, such as bills, notes and bonds issued by the U.S. Treasury; (ii) money market funds; and/or (iii) corporate debt securities, such as commercial paper and other short-term unsecured promissory notes issued by businesses that are rated investment grade or determined by the Defiance ETFs, LLC (the “Adviser”) or sub-adviser to be of comparable quality (collectively, “Collateral”). Such Collateral is designed to provide liquidity, serve as margin or otherwise collateralize the Fund’s investments in the derivatives positions.
The Fund is considered to be non-diversified, which means that it may invest more of its assets in the securities of a single issuer or a smaller number of issuers than if it were a diversified fund. To the extent the Index concentrates (i.e., invests more than 25% of its net assets) in the securities of a particular industry or group of related industries, the Fund will concentrate its investments to approximately the same extent as the Index. As of June 19, 2026, the Index was concentrated in the semiconductors industry within the information technology sector.

BITA AI Advanced Packaging and Testing Index
The Index seeks to track the performance of publicly traded companies with material involvement in the provision of specialized packaging and testing for artificial intelligence (“AI”) semiconductors. The Index captures both suppliers of critical materials, substrates, equipment, and test systems, as well as outsourced semiconductor assembly and test (“OSATs”), foundries, and integrated database management system (“IDMs”) that offer advanced packaging services. Eligible constituents must demonstrate significant thematic exposure to the Index’s theme based on its total revenue derived from, or through its material involvement in, the following segments:
Process Control & Metrology: Companies that provide inspection, measurement, and defect-detection systems for semiconductor wafers and packages. They use optical, electron-beam, and X-ray techniques to verify critical dimensions, film thickness, overlay accuracy, and surface quality at nanometre scales, enabling high yields in advanced packaging production lines.
Wafer-Level Back-End Processing: Companies that perform post-front-end processes while chips are still on the silicon wafer, including redistribution layer (RDL) formation, under-bump metallisation (UBM), copper pillar plating, and through-silicon via (TSV) creation. These steps are essential for fan-out, wafer-level chip-scale packaging (WLCSP), and 3D-IC stacking.
Die Bonding & Assembly: Companies that develop and operate precision pick-and-place, die attach, and thermocompression bonding equipment used to mount individual semiconductor dies onto substrates, interposers, or other dies. They enable high-density interconnection in multi-chip modules, chiplet-based designs, and memory stacks.
Factory Automation & Wafer Handling: Companies that supply automated material handling systems, equipment front end modules (EFEMs), wafer transfer robots, load ports, and stockers for cleanroom environments. Their solutions move wafers, reconstituted wafers, and panels between process tools while maintaining contamination control and traceability.
Silicon Photonics & Co-Packaged Optics (CPO) Equipment: Companies that manufacture assembly, alignment, and test equipment for optical integrated circuits. This includes precision fibre attach, edge coupler alignment, grating coupler testing, and hybrid integration tools that combine electronic and photonic dies into a single package, enabling high-bandwidth, low-power data transmission for AI clusters and high-performance computing.
Test & Burn-In: Companies that provide automated test equipment (ATE), probe cards, load boards, and burn-in systems for semiconductor devices. Their technologies perform functional, parametric, and reliability testing at wafer, singulated die, and package levels, including high-temperature operating life (HTOL) stress to screen early failures in AI, HPC, and memory chips.
Advanced Packaging Substrates & Interposers: Companies that design and fabricate high-density organic, ceramic, or glass substrates and silicon interposers. These components provide fine-pitch interconnect layers (e.g., ABF build-up films), passive routing, and power delivery between chiplets and printed circuit boards, forming the backbone of 2.5D and 3D advanced packages.
Panel-Level Packaging (PLP) Equipment: Companies that develop processing tools (lithography, plating, etching, lamination, bonding) adapted for large rectangular panels rather than circular wafers. Their equipment improves material utilisation and throughput for fan-out packaging on panel substrates up to 600×600 mm or larger, reducing cost per unit for high-volume applications.
Advanced Packaging Materials: Companies that produce specialised chemicals, films, pastes, and underfill materials used in advanced assembly. Key products include dielectric build-up films (e.g., ABF), non-conductive pastes (NCP), capillary underfill (CUF), thermal interface materials (TIM), and wafer-level moulding compounds that ensure electrical insulation, mechanical stability, and heat dissipation.
Memory Packaging & Test: Companies focused on the unique assembly and test requirements of high-bandwidth memory (HBM), DDR5, and 3D NAND. This includes die stacking with through-silicon vias, hybrid bonding, and system-level test solutions for memory-intensive AI accelerators, graphics processors, and server modules.

The Adviser expects that the Index, and consequently the Fund, will generally be concentrated in the securities of the Air, Liquid and Gas Control Equipment Industry Group, and have significant exposure to the Equipment and Supplies Distributors Industry Group, Power Generation and Support Products Industry Group, and Specialty Contracting Services Industry Group.
