About iShares Energy Storage & Materials ETF

IBAT holds a portfolio of US and non-US companies related to energy storage solutions including hydrogen, fuel cells, and batteries. The index selects relevant companies by assessing revenue and patent exposure. For revenue exposure, the index uses granular data to break down revenue sources of eligible companies and identify those most exposed to the theme. For patent-based exposure, specialized metrics are used to screen for companies with high-quality patents and patent specialization linked to the theme. Companies are divided into tiers, depending on revenue and patent exposure. The index applies exclusionary ESG screens to filter out companies non-compliant with global standards, involved with controversial business activities, and have severe controversy ratings. The resulting portfolio is price-weighted with weighting factors based on market capitalization, subject to tier group, company, and concentration capping. The index reconstitutes annually and rebalances quarterly.
