Investing involves risk, principal loss is possible. Unlike mutual funds, ETFs may trade at a premium or discount to their net asset value. Harbor ETFs are new and have limited operating history to judge.

Shares are bought and sold at market price not net asset value (NAV). Market price returns are based upon the closing composite market price and do not represent the returns you would receive if you traded shares at other times.

There is no guarantee that the investment objective of the Fund will be achieved.  Stock markets are volatile and equity values can decline significantly in response to adverse issuer, political, regulatory, market and economic conditions. Since the Fund may hold foreign securities, it may be subject to greater risks than funds invested only in the U.S. These risks are more severe for securities of issuers in emerging market regions. Foreign currencies can decline in value and can adversely affect the dollar value of the fund. Since the Fund typically invests in a limited number of companies, an adverse event affecting a particular company may hurt the Fund's performance more than if it had invested in a larger number of companies. Health Care Industry Risk: Because the Fund seeks to invest all, or substantially all, of its assets in the health care industry, the value of its shares will depend on the general condition of the that industry. The health care industry may be affected by any number of factors, including, but not limited to, lapsing patent protection, industry innovation, extensive government regulation, restrictions on government reimbursement for medical expenses, research and development costs, limited product lines, product liability litigation, an increased emphasis on outpatient services, and competitive forces. Authorized Participant Concentration/Trading Risk: Only authorized participants ("APs") may engage in creation or redemption transactions directly with the Fund. The Fund is classified as non-diversified, a non-diversified Fund may invest a greater percentage of its assets in securities of a single issuer, and/or invest in a relatively small number of issuers, it is more susceptible to risks associated with a single economic, political or regulatory occurrence than a more diversified portfolio. New Fund Risk: There can be no assurance that the Fund will grow to or maintain an economically viable size, in which case the Board of Trustees may determine to liquidate the Fund. Small and Mid Cap Risk: The Fund's performance may be more volatile because it may invest in issuers that are smaller companies.
