#### S\&P 500

The S\&P 500 Index is a free-float capitalization-weighted equity index that tracks the performance of 500 leading publicly traded companies listed in the United States. The index represents large capitalization U.S. equities across all major sectors, including technology, healthcare, financials, consumer discretionary, energy, and industrials, and accounts for approximately 80% of total U.S. market capitalization. It is widely regarded as the primary benchmark for the U.S. large-cap equity market. S\&P Dow Jones Indices has exclusively licensed the S\&P 500 Index<sup>1</sup> to trade\[XYZ] to launch the only officially licensed perpetual contract based on the S\&P 500.

#### XYZ100

The XYZ U.S. 100 Index (XYZ100) is a modified capitalization-weighted equity index that tracks 100 large, non-financial companies listed on a U.S. exchange. The index is designed to concentrate exposure in growth oriented sectors while excluding traditional financial institutions, resulting in a more technology tilted profile relative to broad U.S. benchmarks.
