6 terms

managed distribution policy financial

"declared a second-quarter distribution, pursuant to its managed distribution policy, in the amount of $0.4625 per share"

A managed distribution policy is a company’s plan to pay regular cash to shareholders at a set rate by combining income, dividends and occasional return of capital. Think of it as a scheduled withdrawal from a household account: it can provide steady income for investors, but part of the payment may come from savings rather than ongoing earnings, so investors should watch how those payments are funded and whether they are sustainable over time.

net realized long-term capital gains financial

"Net Realized Long-Term Capital Gains | | | | 100.00 | %"

Net realized long-term capital gains are the total profit an investor actually locks in from selling assets held more than one year, after subtracting any losses or adjustments. Think of it like the net cash you keep after selling a long-owned item and paying off related losses or costs; it matters because these gains determine taxable income and after-tax investment returns, influence dividend capacity and tax planning, and usually face lower tax rates than short-term gains.

return of capital financial

"A return of capital distribution does not necessarily reflect the Fund’s investment performance"

Return of capital is when an investor receives money from their investment that is not considered profit or earnings but rather a portion of the original amount they invested. It’s similar to getting back part of your initial savings rather than gains from it. This matters because it can affect how much money an investor still has in the investment and may have tax implications.

average annual total NAV return financial

"the average annual total return of a share of the Fund’s common stock at net asset value (NAV) for the 5-year period"

closed-end investment company financial

"The Fund is a closed-end investment company that trades on the New York Stock Exchange."

A closed-end investment company is a pooled investment fund that issues a fixed number of shares in a one-time offering and then has those shares bought and sold on an exchange like a stock; a professional manager runs the portfolio of assets. It matters to investors because the market price can move above or below the value of the underlying holdings, affecting returns and income, and shares may be less flexible to issue or redeem compared with open-ended funds—think of buying a slice of a privately baked pie whose market price can differ from the pie’s actual ingredients value.

distribution rate financial

"Annualized Distribution Rate as a Percentage of April 30, 2026 NAV Price"

Distribution rate is the percentage that shows how much income an investment pays out to holders over a year, usually expressed relative to the fund’s share price or net asset value. It tells investors the income they can expect—similar to the interest rate on a savings account—and helps gauge whether a security is delivering steady cash flow or relying on capital to pay distributions, which can signal higher risk.

Columbia Seligman Premium Technology Growth Fund

Announces a Second Quarter Distribution:

9.25% Annual Rate for IPO Investors

Boston, MA – May 8, 2026 – Today, Columbia Seligman Premium Technology Growth Fund, Inc. (NYSE: STK) (the Fund) declared a second-quarter distribution, pursuant to its managed distribution policy, in the amount of $0.4625 per share, which is equal to a quarterly rate of 2.3125% (9.25% annualized) of the $20.00 offering price in the Fund’s initial public offering in November 2009. The first-quarter distribution of $0.4625 per share is equal to a quarterly rate of 0.946% (3.78% annualized) of the Fund’s market price of $48.89 per share as of April 30, 2026.

The distribution will be paid on May 26, 2026 (the Payment Date) to Stockholders of record on May 18, 2026. The ex-dividend date is May 18, 2026. It is anticipated that the Fund will make a subsequent distribution under its managed distribution policy in the month of August.

Prior to the managed distribution policy, the Fund paid distributions pursuant to a level rate distribution policy. Under its former distribution policy and consistent with the Investment Company Act of 1940, as amended, the Fund could not distribute long-term capital gains more often than once in any one taxable year.

In October 2010, the Fund received exemptive relief from the Securities and Exchange Commission that permits the Fund to make periodic distributions of long-term capital gains more often than once in any one taxable year. After consideration by the Fund’s Board, the Fund adopted the current managed distribution policy which allows the Fund to make distributions of long-term capital gains more than once in any taxable year.

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.

		Breakdown of Distribution
Sources		%										US Dollar
Net Investment Income				0.00	%									$0.0000
Net Realized Short-Term Capital Gains				0.00	%									$0.0000
Net Realized Long-Term Capital Gains				100.00	%									$0.4625
Return of Capital or other Capital Source				0.00	%									$0.0000
Total				100.00	%									$0.4625

The following table sets forth the estimated breakdown, on a per share basis, of all distributions made by the Fund during the year-to-date period ended on the Payment Date of the above distributions (includes the distribution payment noted in the table above) 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.

		Breakdown of All Distributions Paid Through Year-To-Date Period Ended on the Payment Date of the Current Distribution
Sources		%										US Dollar
Net Investment Income				0.00	%									$0.0000
Net Realized Short-Term Capital Gains				0.00	%									$0.0000
Net Realized Long-Term Capital Gains				100.00	%									$0.9250
Return of Capital or other Capital Source				0.00	%									$0.0000
Total				100.00	%									$0.9250

In certain years since the Fund’s inception, the Fund has distributed more than its income and net realized capital gains, which has resulted in Fund distributions substantially consisting of return of capital or other capital source. A return of capital may occur, for example, when some or all of the money that you invested in the Fund is paid back to you. A return of capital distribution does not necessarily reflect the Fund’s investment performance and should not be confused with “yield” or “income.” As of the payment date of the current distribution, all Fund distributions paid in 2026 (as estimated by the Fund based on current information) are from the earnings and profits of the Fund and not a return of capital. This could change during the remainder of the year, as further described below.

The amounts, sources and percentage breakdown of the distributions reported above are only estimates and are not being provided for, and should not be used for, tax reporting purposes. The actual amounts, sources and percentage breakdown of the distribution for tax reporting purposes, which may include return of capital, 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 following table sets forth (i) the average annual total return of a share of the Fund’s common stock at net asset value (NAV) for the 5-year period ended April 30, 2026 and (ii) the Fund’s annualized distribution rate for the year-to-date period ended April 30, 2026, expressed as a percentage of the NAV price of a share of the Fund’s common stock at April 30, 2026.

Average Annual Total NAV Return for the 5-year Period Ended April 30, 2026		21.18%
Annualized Distribution Rate as a Percentage of April 30, 2026 NAV Price  (For the Year-to-Date Period ended April 30, 2026)		2.76%

The following table sets forth (i) the cumulative total return (at NAV) of a share of the Fund’s common stock for the year-to-date period ended April 30, 2026, and (ii) the Fund’s distribution rate, for the same period, expressed as a percentage of the NAV price of a share of the Fund’s common stock at April 30, 2026

Cumulative Total NAV Return for the Year-to-Date Period Ended April 30, 2026		34.17%
Distribution Rate as a Percentage of April 30, 2026, NAV Price  (For the Year-to-Date Period Ended April 30, 2026)		0.92%

You should not draw any conclusions about the Fund’s investment performance from the amount of the distributions noted in the tables above or from the terms of the Fund’s distribution policy.

The Fund or your financial professional will send you a Form 1099-DIV for the calendar year that will tell you how to report these distributions on your US federal income tax return. For tax purposes, the Fund is required to report unrealized gains or losses on certain non-US investments as ordinary income or loss, respectively. Accordingly, the amount of the Fund’s total distributions that will be taxable as ordinary income may be different than the amount of the distributions from net investment income reported above.

The Board may change the Fund’s distribution policy and the amount or timing of the distributions, based on a number of factors, including, but not limited to, the amount of the Fund’s undistributed net investment income and net short- and long-term capital gains and historical and projected net investment income and net short- and long-term capital gains.

The Fund is a closed-end investment company that trades on the New York Stock Exchange.

Past performance does not guarantee future results.

Important Disclosures:

You should consider the investment objectives, risks, charges, and expenses of the Fund carefully before investing. A prospectus containing information about the Fund (including its investment objectives, risks, charges, expenses, and other information) may be obtained by contacting your financial advisor or the Fund’s transfer agent at 866-666-1532 or visiting columbiathreadneedleus.com. The prospectus can also be found on the Securities and Exchange Commission’s EDGAR database. The prospectus should be read carefully before investing in the Fund. There is no guarantee that the Fund’s investment goals/objectives will be met or that distributions will be made, and you could lose money.

The Fund expects to receive all or some of its current income and gains from the following sources: (i) dividends received by the Fund that are paid on the equity and equity-related securities in its portfolio; and (ii) capital gains (short-term and long-term) from option premiums and the sale of portfolio securities. It is possible that the Fund’s distributions will at times exceed the earnings and profits of the Fund and therefore all or a portion of such distributions may constitute a return of capital as described below. A return of capital is a return of your original investment. A return of capital distribution does not necessarily reflect the Fund’s investment performance and should not be confused with “yield” or “income.” You should not draw any conclusions about the Fund’s investment performance from the amount of this distribution or from the Fund’s distribution policy.

Distributions that qualify as a return of capital are a return of some or all of your original investment in the Fund. A return of capital reduces a stockholder’s tax basis in his or her shares. Once the tax basis in your shares has been reduced to zero, any further return of capital may be taxable as capital gain. Shareholders should consult their tax advisor or tax attorney for proper treatment.

Distributions may be variable, and the Fund’s distribution rate will depend on a number of factors, including the net earnings on the Fund’s portfolio investments and the rate at which such net earnings change as a result of changes in the timing of, and rates at which, the Fund receives income from the sources noted above. As portfolio and market conditions change, the rate of distributions on the shares and the Fund’s distribution policy could change.

Market risk may affect a single issuer, sector of the economy, industry or the market as a whole. The products of technology companies may be subject to severe competition and rapid obsolescence, and their stocks may be subject to greater price fluctuations. Investments in small- and mid-cap companies involve risks and volatility greater than investments in larger, more established companies. Foreign investments subject the fund to risks, including political, economic, market, social and others within a particular country, as well as to currency instabilities and less stringent financial and accounting standards generally applicable to U.S. issuers. As a non-diversified fund, fewer investments could have a greater effect on performance. The Fund’s derivatives strategies may not be successful and could result in significant Fund losses.

The Fund should only be considered as one element of a complete investment program. An investment in the Fund should be considered speculative. The Fund’s investment policy of investing in technology and technology-related companies and writing call options involves a high degree of risk.

There is no assurance that the Fund will meet its investment objectives or that distributions will be made. You could lose some or all of your investment. In addition, closed-end funds frequently trade at a discount to their net asset values, which may increase your risk of loss.

The Fund is not insured by the FDIC, NCUA or any federal agency, is not a deposit or obligation of, or guaranteed by any financial institution, and involves investment risks including possible loss of principal and fluctuation in value.
