Normally investing primarily in common stocks. Normally investing at least 80% of assets in blue chip companies (companies that, in Fidelity Management & Research Company LLC (FMR)'s view, are well-known, well-established and well-capitalized), which generally have large or medium market capitalizations. Investing in companies that FMR believes are undervalued in the marketplace in relation to factors such as assets, sales, earnings, growth potential, or cash flow, or in relation to securities of other companies in the same industry (stocks of these companies are often called "value" stocks). Investing in domestic and foreign issuers. Using fundamental analysis of factors such as each issuer's financial condition and industry position, as well as market and economic conditions, to select investments. Effective December 11, 2025, normally investing at least 80% of assets in securities of blue chip value companies. Blue chip companies are companies that, in the Adviser's view, are well-known, well-established and well-capitalized, which, for purposes of this fund, are companies with a higher market capitalization than the lowest capitalized company in any of the S&P 500 Index, Russell 1000 Index, or Dow Jones Industrial Average. Although blue chip companies generally have large or medium market capitalizations, the Adviser may invest in companies that it believes have good, long-term prospects to become blue chip companies. Value companies are companies the Adviser believes are undervalued in the marketplace. The Adviser considers traditional and other measures of value, such as whether the company is included in a third-party value benchmark or classified as a value company by a third-party vendor, whether the company's free cash flow yield is above the equity market median, whether the company's enterprise value (the total value of a company's outstanding equity and debt) relative to earnings is below the equity market median, or whether the company's price-to-book (P/B) ratio or projected price-to-earnings (P/E) ratio is below the equity market median. An issuer may be determined to be a value company under any of these factors. Derivative instruments that provide investment exposure to the investments above or exposure to one or more market risk factors associated with such investments are included in the fund's 80% policy, consistent with the fund's investment policies and limitations with respect to investments in derivatives. Proposed Reorganization . The Board of Trustees of Fidelity Advisor Series VIII has unanimously approved an Agreement and Plan of Reorganization ("Agreement") between Fidelity Advisor® Value Leaders Fund and Fidelity® Blue Chip Value Fund pursuant to which Fidelity Advisor® Value Leaders Fund would be reorganized on a tax-free basis with and into Fidelity® Blue Chip Value Fund.  As a result of the proposed Reorganization, shareholders of Fidelity Advisor® Value Leaders Fund would receive, respectively, corresponding shares of Fidelity® Blue Chip Value Fund. The Agreement provides for the transfer of all of the assets of Fidelity Advisor® Value Leaders Fund in exchange for corresponding shares of Fidelity® Blue Chip Value Fund equal in value to the net assets of Fidelity Advisor® Value Leaders Fund and the assumption by Fidelity® Blue Chip Value Fund of all of the liabilities of Fidelity Advisor® Value Leaders Fund. After the exchange, Fidelity Advisor® Value Leaders Fund will distribute the Fidelity® Blue Chip Value Fund shares to its shareholders pro rata, in liquidation of Fidelity Advisor® Value Leaders Fund. As a result, shareholders of Fidelity Advisor® Value Leaders Fund will become shareholders of Fidelity® Blue Chip Value Fund (these transactions are collectively referred to as the "Reorganization").  A Special Meeting (the "Meeting") of the Shareholders of Fidelity Advisor® Value Leaders Fund is expected to be held during the second quarter of 2025 and approval of the Agreement will be voted on at that time. A combined proxy statement and prospectus containing more information with respect to the Reorganization will be provided to shareholders of record of Fidelity Advisor® Value Leaders Fund in advance of the meeting. If the Agreement is approved at the Meeting and certain conditions required by the Agreement are satisfied, the Reorganization is expected to take place on or about May 9, 2025. If shareholder approval of the Agreement is delayed due to failure to meet a quorum or otherwise, the Reorganization will become effective, if approved, as soon as practicable thereafter.  Effective after the close of business on or about May 8, 2025, new positions in the fund may no longer be opened. Existing shareholders may continue to hold their shares and purchase additional shares through the reinvestment of dividend and capital gain distributions until the fund's Reorganization takes place.   The foregoing is not a solicitation of any proxy.
