BlackRock Science and Technology Trust (BST) and BlackRock Science and Technology Term Trust (BSTZ) Announce Special Distributions

BlackRock Science and Technology Trust (NYSE:BST) and BlackRock Science and Technology Term Trust (NYSE:BSTZ) (each, a "Fund" and together, the "Funds") announced today the declaration of special distributions, payable on September 30, 2026 to shareholders of record as of September 15, 2026 (ex-date September 15, 2026).

The special distributions reflect substantial realized gains generated by the Funds' strong investment performance, including cumulative fiscal year-to-date returns of 32.7% for BST and 44.5% for BSTZ, and three-year annualized returns of 27.8% for BST and 30.4% for BSTZ¹. These gains reflect the investment team's disciplined approach to identifying and capturing opportunities across public and private companies in the technology ecosystem. Through investments in both public and private technology companies, BST and BSTZ offer shareholders access to long-term innovation themes such as artificial intelligence. By declaring these special distributions mid-year, the Funds are returning a portion of realized gains to shareholders while helping manage year-end tax distribution requirements.

The special distributions, which are in addition to each Fund’s regular monthly distributions previously declared for September 2026, are summarized in the tables below:

Note: The final distribution dollar amount will be finalized on the ex-date based upon current shares outstanding and subject to rounding.

*In order to comply with the requirements of Section 19 of the Investment Company Act of 1940, as amended (the "1940 Act"), each of the Funds noted above posted to the DTC bulletin board and sent to its shareholders of record as of the applicable record date a Section 19 notice with the previous distribution payment. The Section 19 notice was provided for informational purposes only and not for tax reporting purposes. This information can be found in the "Closed-End Funds" section of www.blackrock.com. As applicable, the final determination of the source and tax characteristics of all distributions in 2026 will be made after the end of the year.

The fixed amounts distributed per share or distribution rate, as applicable, are subject to change at the discretion of each Fund’s Board of Directors/Trustees. Under its Plan, each Fund will distribute all available investment income to its shareholders, consistent with its investment objectives and as required by the Internal Revenue Code of 1986, as amended (the "Code"). If sufficient income (inclusive of net investment income and short-term capital gains) is not available monthly, a Fund will distribute long-term capital gains and/or return capital to its shareholders in order to maintain a level distribution.

Each Fund’s estimated sources of distributions payable July 31, 2026, and for its current fiscal year are as follows:

The amounts and sources of the distribution reported are only estimates and are being provided to you pursuant to regulatory requirements and are not being provided for tax reporting purposes. The actual amounts and sources of the amounts for tax reporting purposes will depend upon the Fund’s investment experience during the remainder of its fiscal year and may be subject to changes based on tax regulations. The Fund will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions for federal income tax purposes.

Shareholders should not draw any conclusions about the Fund’s investment performance from the amount of the Fund’s current distributions or from the terms of the Fund’s Plan.
