The ProShares Bitcoin/Blockchain Strategy ETF contains portfolio investments that are primarily listed on foreign markets. To the extent the Fund’s portfolio investments trade in foreign markets on days when the Fund is not open for business or when the primary exchange for its shares is not open, the value of the Fund’s assets may vary on days when shareholders may not be able to purchase or sell Fund shares and Authorized Participants may not be able to create or redeem Creation Units. Also, certain portfolio investments may not be traded on days the Fund is open for business.
