Columbia Seligman Premium Technology Growth Fund Inc. declared a special fourth quarter distribution, beyond its typical quarterly managed distribution policy, in the amount of $0.2669 per share. 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 current fiscal year exceeds the amounts previously distributed pursuant to the Fund?s quarterly managed distribution policy.

The Fund is distributing this excess income so that it will not incur the 4% federal excise tax in 2023. The distribution will be paid on January 23, 2024 (the Payment Date) to stockholders of record on December 18, 2023 (the Record Date). The ex-dividend date is December 15, 2023.
