BlackRock Science and Technology Term Trust (NYSE: BSTZ) Dear Shareholder: I am writing with important information about your upcoming 2024 Annual Shareholder Meeting for BlackRock Science and Technology Term Trust (NYSE: BSTZ) (the “Fund”). In the next few weeks, you will receive BSTZ’s proxy statement and WHITE proxy card. I urge you to review the proposals and protect your long-term investment by promptly voting your shares on the WHITE proxy card when you receive it. Your fund is under attack This year, your voice matters more than ever. A well-known activist hedge fund, Saba Capital Management L.P. (“Saba”), is once again attacking your long-term investment and threatening actions that we believe would harm the Fund and all shareholders by attempting to: • Take control of the Fund’s board with a slate of inexperienced, hand-picked candidates • Fire BlackRock as investment advisor to the Fund This would deprive shareholders of BlackRock’s and the Board’s expertise and potentially imperil the Fund’s ability to generate your consistent income and returns. In addition, if Saba were to succeed, it may seek to appoint itself as investment advisor and/or fundamentally disrupt BSTZ’s investment objectives and strategies, all to enrich itself. Your experienced Board and distinguished management team have consistently worked to meet BSTZ’s investment objectives to provide total return and income through a combination of current income, current gains and long-term capital appreciation. Under their stewardship, the Fund has enhanced shareholder value through share repurchases and attractive monthly payments to shareholders. Your Board and management team are committed to protecting and advancing the interests of all shareholders, not just a few. BSTZ delivers for all shareholders… 18% shareholder return year to date in 2024, Independent, experienced and proven Board outperforming 98% of all closed-end funds 19% shareholder return in 2023, $42 million in share repurchases at a discount, outperforming 80% of all closed-end funds enhancing value for shareholders Income alternative for investors seeking 100% liquidity at net asset value via term structure access to leading artificial intelligence technologies including private companies We ask all shareholders to support their long-term investment in the fund. As always, we will continue to prioritize your best interests and help you meet your financial goals. Thank you for your continued loyalty and support. Sincerely, John M. Perlowski President and Chief Executive Officer 1
