Invesco S&P MidCap 400 Pure Growth ETF (RFG) Exchange: NYSE ARCA

The Fund generally will invest at least 90% of its total assets in the securities that comprise the Underlying Index. Strictly in accordance with its guidelines and mandated procedures, S&P Dow Jones Indices LLC (“S&P DJI” or the “Index Provider”) compiles, maintains and calculates the Underlying Index, which is composed of a subset of securities from the S&P MidCap 400® Index (the “Parent Index”) that exhibit strong growth characteristics. First, each security in the Parent Index is assigned two “style scores” – one for growth and one for value – based on the characteristics of the issuer. The “growth score” is measured using three factors: three-year sales per share growth, three-year ratio of earnings per share change to price per share, and momentum (the 12-month percentage change in price). The “value score” is measured using three other factors: book-value-to-price ratio, earnings-to-price ratio, and sales-to-price ratio. The securities in the Parent Index are ranked based on their scores. Unlike other style indices that may contain all securities within the Parent Index, including overlapping constituents that exhibit both growth and value characteristics, the Underlying Index is narrower in focus and excludes any overlapping securities demonstrating both growth and value characteristics. The Underlying Index uses a “style-attractiveness weighting” scheme, such that securities demonstrating the strongest growth characteristics receive proportionally greater weights. As of June 30, 2020, the Underlying Index was comprised of 90 constituents with market capitalizations ranging from $1.4 billion to $14 billion. The Fund employs a “full replication” methodology in seeking to track the Underlying Index, meaning that the Fund generally invests in all of the securities comprising the Underlying Index in proportion to their weightings in the Underlying Index. The Fund is “non-diversified” and, therefore, is not required to meet certain diversification requirements under the Investment Company Act of 1940, as amended (the “1940 Act”). Concentration Policy. The Fund will concentrate its investments (i.e., invest more than 25% of the value of its net assets) in securities of issuers in any one industry or group of industries only to the extent that the Underlying Index reflects a concentration in that industry or group of industries. The Fund will not otherwise concentrate its investments in securities of issuers in any one industry or group of industries. As of April 30, 2020, the Fund had significant exposure to the information technology sector. The Fund’s portfolio holdings, and the extent to which it concentrates its investments, are likely to change over time.
