Columbia Seligman Premium Technology Growth Fund Announces a Fourth Quarter Distribution

Today, Columbia Seligman Premium Technology Growth Fund, Inc. (NYSE: STK) (the Fund) declared a fourth quarter distribution, that is beyond its typical quarterly managed distribution, in the total amount of $1.3280 per share of common stock (which includes the Fund’s typical quarterly $0.4625 per share distribution). A federal excise tax of 4% applies to funds that do not distribute substantially all of their annual income (including net gains) before the end of their fiscal year. The Fund’s income for the 2025 fiscal year exceeds the amounts previously distributed pursuant to the Fund’s quarterly managed distribution policy. The Fund is including this excess income – beyond the Fund’s typical quarterly distribution – in the fourth quarter distribution so that it will not incur the 4% federal excise tax in 2025.

The distribution will be paid on December 9, 2025 (the Payment Date) to stockholders of record on November 17, 2025 (the Record Date). The ex-dividend date is November 17, 2025. Because all of the distribution is expected to be a special capital gain distribution, it will automatically be paid in stock except that any Record Date stockholder may elect to receive the distribution in cash by contacting, as applicable, their financial advisor (for shareholders who hold shares through a financial intermediary, such as a broker-dealer) or the Fund’s stockholder servicing agent, Equiniti Trust Company, LLC, whose contact information appears below (for shareholders who hold shares directly with the Fund), by 5 pm Eastern Time on December 2, 2025. It is anticipated that the Fund will make its next distribution under its managed distribution policy in the month of February.

The following table sets forth the estimated breakdown of the distribution noted above, on a per share basis, from the following sources: net investment income; net realized short-term capital gains; net realized long-term capital gains; and return of capital or other capital source.
