(Unaudited)

Under the managed distribution policy of Columbia Seligman Premium Technology Growth Fund, Inc. (the Fund) and subject to the approval of the Fund’s Board of Directors (the Board), the Fund expects to make quarterly cash distributions (in February, May, August and November) to holders of common stock (Common Stockholders). The Fund’s most recent distribution under its managed distribution policy (paid on August 25, 2026) amounted to $0.4625 per share, which is equal to a quarterly rate of 0.9421% (3.77% annualized) of the Fund’s market price of $49.09 per share as of July 31, 2026. You should not draw any conclusions about the Fund’s investment performance from the amount of the distributions or from the terms of the Fund’s managed distribution policy. Historically, the Fund has at times 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”. The Fund’s Board may determine in the future that the Fund’s managed distribution policy and the amount or timing of the distributions should not be continued in light of changes in the Fund’s portfolio holdings, market or other conditions or factors, including that the distribution rate under such policy may not be dependent upon the amount of the Fund’s earned income or realized capital gains. The Board could also consider amending or terminating the current managed distribution policy because of potential adverse tax consequences associated with maintaining the policy. In certain situations, returns of capital could be taxable for federal income tax purposes, and all or a portion of the Fund’s capital loss carryforwards from prior years, if any, could effectively be forfeited. The Board may amend or terminate the Fund’s managed distribution policy at any time without prior notice to Fund stockholders; any such change or termination may have an adverse effect on the market price of the Fund’s shares.

See Notes to Financial Statements for additional information related to the Fund’s managed distribution policy.

FUND INVESTMENT OBJECTIVE, STRATEGIES, POLICIES AND PRINCIPAL RISKS

(Unaudited)

Fund Investment Objective

The Fund’s investment objective is to seek growth of capital and current income. The Fund’s investment objective is

non-fundamental

and may be changed by the Board without approval of the Fund’s stockholders.

Fund Investment Strategies and Policies

Under normal market conditions, the Fund invests at least 80% of its “Managed Assets” (as defined below) in a portfolio of equity securities of technology and technology-related companies that Columbia Management Investment Advisers, LLC (the Investment Manager) believes offer attractive opportunities for capital appreciation. Under normal market conditions, the Fund’s investment program consists primarily of (i) investing in a portfolio of common stocks of technology and technology-related companies that seeks to exceed the total return, before fees and expenses, of the S&P North American Technology Sector Index (described further below) and (ii) writing call options on the NASDAQ 100 Index

, an unmanaged index of the 100 largest

non-financial

domestic and international companies listed on the NASDAQ Stock Market based on market capitalization, or an exchange-traded fund (ETF) equivalent (the NASDAQ 100) on a

month-to-month

basis, with an aggregate notional amount typically ranging from

0%-90%

of the underlying value of the Fund’s holdings of common stock (the Rules-based Option Strategy, as further described below). The Fund expects to generate current income from premiums received from writing call options on the NASDAQ 100. The Fund concentrates its investments in technology and technology-related stocks. The Fund may invest in companies of any size, including small-,

mid-,

and

large-cap

companies, as well as foreign companies.

Technology and technology-related companies in which the Fund invests are companies operating in the information technology and communications services sectors, as well as other related industries, applying a global industry classification standard, as it may be amended from time to time, to determine industry/sector classifications. These related industry companies may also include companies operating in the consumer discretionary and healthcare sectors, particularly those that are principally engaged in offering or developing products, processes, or services that benefit significantly from technological advances and improvements. By way of example, technology and technology-related companies may include semiconductor, semiconductor equipment, technology hardware, storage and peripherals, software, communication equipment and services, electronic equipment and instruments, internet services and infrastructure, media, health care equipment and supplies, and medical technology companies. The Fund tends to focus its technology and technology-related investments on companies in the information technology sector and/or the semiconductor and semiconductor equipment industry.

In determining the level (i.e., 0% to 90%) of call options to be written on the NASDAQ 100, the Investment Manager’s Rules-based Option Strategy is based on the CBOE

NASDAQ-100

Volatility IndexSM (the VXN Index). The VXN Index measures the market’s expectation of

30-day

volatility implicit in the prices of near-term NASDAQ 100 Index options. The VXN Index, which is quoted in percentage points (e.g., 19.36), is a leading barometer of investor sentiment and market volatility relating to the NASDAQ 100 Index. In general, the Investment Manager intends to write more call options when market volatility, as represented by the VXN Index, is high (and premiums received for writing the option are high) and write fewer call options when market volatility, as represented by the VXN Index, is low (and premiums for writing the option are low).

The Fund’s Rules-based Option Strategy with respect to writing call options is as follows:


When the VXN Index is:	Aggregate Notional Amount of Written Call Option as a Percentage of the Fund’s Holdings in Common Stocks
17 or less		25	%
Greater than 17, but less than 18		Increase up to 50	%
At least 18, but less than 33		50	%
At least 33, but less than 34		Increase up to 90	%
At least 34, but less than 55		90	%
At 55 or greater		0% to 90	%


4		Columbia Seligman Premium Technology Growth Fund, Inc. \| 2026

FUND INVESTMENT OBJECTIVE, STRATEGIES, POLICIES AND PRINCIPAL RISKS (continued)

(Unaudited)

In addition to the Rules-based Option Strategy, the Fund may write additional calls with aggregate notional amounts of up to 25% of the value of the Fund’s holdings in common stock (to a maximum of 90% when aggregated with the call options written pursuant to the Rules-based Option Strategy) when the Investment Manager believes call premiums are attractive relative to the risk of the price of the NASDAQ 100. The Fund may also close (or buy back) a written call option if the Investment Manager believes that a substantial amount of the premium (typically, 70% or more) to be received by the Fund has been captured before exercise, potentially reducing the call position to 0% of total equity until additional calls are written. The Fund, subject to the above-mentioned aggregate notional amount of 90% of the underlying value of the Fund’s holdings of common stock, may also buy or write other call and put options on securities, indices, ETFs and market baskets of securities to generate additional income or return or to provide the portfolio with downside protection.

The S&P North American Technology Sector Index is a benchmark that represents U.S. securities classified under the GICS

information technology sector as well as the internet and direct marketing retail, interactive home entertainment, and interactive media and services

sub-industries.

The Fund’s investment policy of investing at least 80% of its Managed Assets in equity securities of technology and technology-related companies and its policy with respect to the use of the Rules-based Option Strategy on a

month-to-month

basis may be changed by the Board without stockholder approval only with 60 days’ prior written notice to stockholders.

The Fund is a

non-diversified

fund. A

non-diversified

fund is permitted to invest a greater percentage of its total assets in fewer issuers than a diversified fund. This policy may not be changed without a stockholder vote.

The Fund has a fundamental policy of investing at least 25% of the value of its Managed Assets in technology and technology-related stocks. This policy may not be changed without a stockholder vote. The Fund may also invest: up to 15% of its Managed Assets in illiquid securities (i.e., securities that at the time of purchase are not readily marketable); up to 20% of its Managed Assets in debt securities (including convertible and

non-convertible

debt securities), such as debt securities issued by technology and technology-related companies and obligations of the U.S. Government, its agencies and instrumentalities, and government-sponsored enterprises, as well as below-investment grade securities (i.e., high-yield or junk bonds); and up to 25% of its Managed Assets in equity securities of companies organized outside of the United States. The Fund may hold foreign securities of issuers located or doing substantial business in emerging markets. Each of these policies may be changed by the Board without stockholder approval.

The Fund has other fundamental policies that may not be changed without a stockholder vote. Under these policies, the Fund may not:

•

Purchase or sell commodities or commodity contracts, except to the extent permissible under applicable law and interpretations, as they may be amended from time to time, and except this shall not prevent the Fund from buying or selling options, futures contracts and foreign currency or from entering into forward currency contracts or from investing in securities or other instruments backed by, or whose value is derived from, physical commodities;

•

Issue senior securities or borrow money, except as permitted by the Investment Company Act of 1940, as amended (1940 Act) or any rule thereunder, any Securities and Exchange Commission (SEC) or SEC staff interpretations thereof or any exemptions therefrom which may be granted by the SEC;

•

Make loans, except as permitted by the 1940 Act or any rule thereunder, any SEC or SEC staff interpretations thereof or any exemptions therefrom which may be granted by the SEC;

•

Underwrite the securities of other issuers, except insofar as the Fund may be deemed an underwriter under the Securities Act of 1933 (1933 Act) in disposing of a portfolio security or in connection with investments in other investment companies;

•

Buy or sell real estate, unless acquired as a result of ownership of securities or other instruments, except this shall not prevent the Fund from investing in securities or other instruments backed by real estate or securities of companies engaged in the real estate business or real estate investment trusts; and


Columbia Seligman Premium Technology Growth Fund, Inc. \| 2026			5

FUND INVESTMENT OBJECTIVE, STRATEGIES, POLICIES AND PRINCIPAL RISKS (continued)

(Unaudited)

•

Invest 25% or more of its Managed Assets (as defined below), at market value, in the securities of issuers in any particular industry, except that the Fund will invest at least 25% of the value of its Managed Assets in technology and technology-related stocks (in which the Fund intends to concentrate) and may invest without limit in securities issued or guaranteed by the U.S. Government, its agencies or instrumentalities, or government-sponsored enterprises, as described in the Fund’s prospectus, which may be amended from time to time.

“Managed Assets” means the net asset value of the Fund’s outstanding common shares plus any liquidation preference of any issued and outstanding shares of Fund preferred stock (“Preferred Shares”) and the principal amount of any borrowings used for leverage.

Certain of the Fund’s fundamental policies set forth above prohibit transactions “except as permitted by the 1940 Act or any rule thereunder, any SEC or SEC staff interpretations thereof or any exemptions therefrom which may be granted by the SEC.” The following discussion summarizes the flexibility that the Fund currently gains from these exceptions. To the extent the 1940 Act or the rules and regulations thereunder may, in the future, be amended to provide greater flexibility, or to the extent the SEC may in the future grant exemptive relief providing greater flexibility, the Fund will be able to use that flexibility without seeking shareholder approval of its fundamental policies.

Issuing senior securities — A “senior security” is an obligation with respect to the earnings or assets of a company that takes precedence over the claims of that company’s common stock with respect to the same earnings or assets. The 1940 Act limits a

closed-end

fund’s issuance of senior securities, but Rule

18f-4

provides relief from that prohibition as to certain transactions that could be considered issuances of senior securities, provided that the Fund complies with its conditions. The exception in the fundamental policy allows the Fund to operate in accordance with Rule

18f-4.

Borrowing money — The 1940 Act permits the Fund to borrow up to 33 1/3% of its Managed Assets, plus an additional 5% of its Managed Assets for temporary purposes. The Fund’s compliance with its policy on borrowing is not determined by applying the time of purchase standard.

Making loans — The 1940 Act generally prohibits the Fund from making loans to affiliated persons but does not otherwise restrict the Fund’s ability to make loans.

Under the 1940 Act, the Fund’s fundamental policies may not be changed without the approval of the holders of a “majority of the outstanding” common shares and, if issued, preferred shares voting together as a single class, and of the holders of a “majority of the outstanding” preferred shares voting as a separate class. When used with respect to particular shares of the Fund, a “majority of the outstanding” shares means the lesser of: (i) 67% or more of the shares present at a stockholder meeting, if the holders of more than 50% of the outstanding shares are present at the meeting or represented by proxy, or (ii) more than 50% of the outstanding shares of the Fund.

Principal Risks

An investment in the Fund involves risks. The principal risks of investing in the Fund are provided below. There is no assurance that the Fund will achieve its investment objective and you may lose money. The value of the Fund’s holdings may decline, and the Fund’s net asset value (NAV) and share price may go down. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The significance of any specific risk to an investment in the Fund will vary over time depending on the composition of the Fund’s portfolio, market conditions, and other factors. You should read all of the risk information below carefully, because any one or more of these risks may result in losses to the Fund. See also the Fund’s “Risks and uncertainties” in the Notes to Financial Statements section.

Active Management Risk.

The Fund is actively managed and its performance therefore will reflect, in part, the ability of the portfolio managers to make investment decisions that seek to achieve the Fund’s investment objective. Due to its active management, the Fund could underperform its benchmark index and/or other funds with similar investment objectives and/ or strategies.


6		Columbia Seligman Premium Technology Growth Fund, Inc. \| 2026

FUND INVESTMENT OBJECTIVE, STRATEGIES, POLICIES AND PRINCIPAL RISKS (continued)

(Unaudited)

Counterparty Risk.

The risk exists that a counterparty to a transaction in a financial instrument held by the Fund or by a special purpose or structured vehicle in which the Fund invests may become insolvent or otherwise fail to perform its obligations, including making payments to the Fund, due to financial difficulties. The Fund may obtain no or limited recovery in a bankruptcy or other reorganizational proceedings, and any recovery may be significantly delayed. Transactions that the Fund enters into may involve counterparties in the financial services sector and, as a result, events affecting the financial services sector may cause the Fund’s NAV to fluctuate.

Credit Risk.

Credit risk is the risk that the value of debt instruments may decline if the issuer thereof defaults or otherwise becomes unable or unwilling, or is perceived to be unable or unwilling, to honor its financial obligations, such as making payments to the Fund when due. Various factors could affect the actual or perceived willingness or ability of the issuer to make timely interest or principal payments, including changes in the financial condition of the issuer or in general economic conditions. Credit rating agencies, such as S&P Global Ratings, Moody’s Ratings, Fitch, DBRS and KBRA, assign credit ratings to certain debt instruments to indicate their credit risk. A rating downgrade by such agencies can negatively impact the value of such instruments. Lower-rated or unrated instruments held by the Fund may present increased credit risk as compared to higher-rated instruments.

Non-investment

grade debt instruments may be subject to greater price fluctuations and are more likely to experience a default than investment grade debt instruments and therefore may expose the Fund to increased credit risk. If the Fund purchases unrated instruments, or if the ratings of instruments held by the Fund are lowered after purchase, the Fund will depend on analysis of credit risk more heavily than usual.

Derivatives Risk.

Derivatives may involve significant risks. Derivatives are financial instruments, traded on an exchange or in the

over-the-counter

(OTC) markets, with a value in relation to, or derived from, the value of an underlying asset(s) (such as a security, commodity or currency) or other reference, such as an index, rate or other economic indicator (each an underlying reference). Derivatives may include those that are privately placed or otherwise exempt from SEC registration, including certain Rule 144A eligible securities. Derivatives could result in Fund losses if the underlying reference does not perform as anticipated. Use of derivatives is a highly specialized activity that can involve investment techniques, risks, and tax planning different from those associated with more traditional investment instruments. The Fund’s derivatives strategy may not be successful and use of certain derivatives could result in substantial, potentially unlimited, losses to the Fund regardless of the Fund’s actual investment. A relatively small movement in the price, rate or other economic indicator associated with the underlying reference may result in substantial losses for the Fund. Derivatives may be more volatile than other types of investments. Derivatives can increase the Fund’s risk exposure to underlying references and their attendant risks, including the risk of an adverse credit event associated with the underlying reference (credit risk), the risk of an adverse movement in the value, price or rate of the underlying reference (market risk), the risk of an adverse movement in the value of underlying currencies (foreign currency risk) and the risk of an adverse movement in underlying interest rates (interest rate risk). Derivatives may expose the Fund to additional risks, including the risk of loss due to a derivative position that is imperfectly correlated with the underlying reference it is intended to hedge or replicate (correlation risk), the risk that a counterparty will fail to perform as agreed (counterparty risk), the risk that a hedging strategy may fail to mitigate losses, and may offset gains (hedging risk), the risk that the return on an investment may not keep pace with inflation (inflation risk), the risk that losses may be greater than the amount invested (leverage risk), the risk that the Fund may be unable to sell an investment at an advantageous time or price (liquidity risk), the risk that the investment may be difficult to value (pricing risk), and the risk that the price or value of the investment fluctuates significantly over short periods of time (volatility risk). The value of derivatives may be influenced by a variety of factors, including national and international political and economic developments. Potential changes to the regulation of the derivatives markets may make derivatives more costly, may limit the market for derivatives, or may otherwise adversely affect the value or performance of derivatives.

Derivatives Risk – Options Risk.

Options are derivatives that give the purchaser the option to buy (call) or sell (put) an underlying reference from or to a counterparty at a specified price (the strike price) on or before an expiration date. The Fund may purchase or write (i.e., sell) put and call options on an underlying reference it is otherwise permitted to invest in. When writing options, the Fund is exposed to the risk that it may be required to buy or sell the underlying reference at a disadvantageous price on or before the expiration date. If the Fund sells a put option, the Fund may be required to buy the underlying reference at a strike price that is above market price, resulting in a loss. If the Fund sells a call option, the Fund may be required to sell the underlying reference at a strike price that is below market price, resulting in a loss. If the Fund


Columbia Seligman Premium Technology Growth Fund, Inc. \| 2026			7

FUND INVESTMENT OBJECTIVE, STRATEGIES, POLICIES AND PRINCIPAL RISKS (continued)

(Unaudited)

sells a call option that is not covered (it does not own the underlying reference), the Fund’s losses are potentially unlimited. Options may involve economic leverage, which could result in greater volatility in price movement. Options may be traded on a securities exchange or in the

over-the-counter

market. At or prior to maturity of an options contract, the Fund may enter into an offsetting contract and may incur a loss to the extent there has been adverse movement in options prices. Options can increase the Fund’s risk exposure to underlying references and their attendant risks such as credit risk, market risk, foreign currency risk and interest rate risk, while potentially exposing the Fund to correlation risk, counterparty risk, hedging risk, inflation risk, leverage risk, liquidity risk, pricing risk and volatility risk.

Foreign Securities Risk.

Investments in or exposure to securities of foreign companies may involve heightened risks relative to investments in or exposure to securities of U.S. companies. For example, foreign markets can be extremely volatile. Foreign securities may also be less liquid, making them more difficult to trade, than securities of U.S. companies so that the Fund may, at times, be unable to sell foreign securities at desirable times or prices. Brokerage commissions, custodial costs and other fees are also generally higher for foreign securities. The Fund may have limited or no legal recourse in the event of default with respect to certain foreign securities, including those issued by foreign governments. In addition, foreign governments may impose withholding or other taxes on the Fund’s income, capital gains or proceeds from the disposition of foreign securities, which could reduce the Fund’s return on such securities. In some cases, such withholding or other taxes could potentially be confiscatory. Other risks include: possible delays in the settlement of transactions or in the payment of income; generally less publicly available information about foreign companies; the impact of economic, political, social, diplomatic or other conditions or events (including, for example, military confrontations and actions, war, other conflicts, terrorism and disease/virus outbreaks and epidemics), possible seizure, expropriation or nationalization of a company or its assets or the assets of a particular investor or category of investors; accounting, auditing and financial reporting standards that may be less comprehensive and stringent than those applicable to domestic companies; the imposition of economic and other sanctions against a particular foreign country, its nationals or industries or businesses within the country; and the generally less stringent standard of care to which local agents may be held in the local markets. In addition, it may be difficult to obtain reliable information about the securities and business operations of certain foreign issuers. Governments or trade groups may compel local agents to hold securities in designated depositories that are not subject to independent evaluation. The less developed a country’s securities market is, the greater the level of risks. Economic sanctions may be, and have been, imposed against certain countries, organizations, companies, entities and/or individuals. Economic sanctions and other similar governmental actions could, among other things, effectively restrict or eliminate the Fund’s ability to purchase or sell securities, and thus may make the Fund’s investments in such securities less liquid or more difficult to value. In addition, as a result of economic sanctions, the Fund may be forced to sell or otherwise dispose of investments at inopportune times or prices, which could result in losses to the Fund and increased transaction costs. These conditions may be in place for a substantial period of time and enacted with limited advance notice to the Fund. The risks posed by sanctions against a particular foreign country, its nationals or industries or businesses within the country may be heightened to the extent the Fund invests significantly in the affected country or region or in issuers from the affected country that depend on global markets. Additionally, investments in certain countries may subject the Fund to a number of tax rules, the application of which may be uncertain. Countries may amend or revise their existing tax laws, regulations and/or procedures in the future, possibly with retroactive effect. Changes in or uncertainties regarding the laws, regulations or procedures of a country could reduce the

after-tax

profits of the Fund, directly or indirectly, including by reducing the

after-tax

profits of companies located in such countries in which the Fund invests, or result in unexpected tax liabilities for the Fund. The performance of the Fund may also be negatively affected by fluctuations in a foreign currency’s strength or weakness relative to the U.S. dollar, particularly to the extent the Fund invests a significant percentage of its assets in foreign securities or other assets denominated in currencies other than the U.S. dollar. Currency rates in foreign countries may fluctuate significantly over short or long periods of time for a number of reasons, including changes in interest rates, imposition of currency exchange controls and economic or political developments in the U.S. or abroad. The Fund may also incur currency conversion costs when converting foreign currencies into U.S. dollars and vice versa.

Interest Rate Risk.

Interest rate risk is the risk of losses attributable to changes in interest rates. In general, if interest rates rise, the values of debt instruments tend to fall, and if interest rates fall, the values of debt instruments tend to rise. Changes in the value of a debt instrument usually will not affect the amount of income the Fund receives from it but will generally affect the value of your investment in the Fund. Changes in interest rates may also affect the liquidity of the


8		Columbia Seligman Premium Technology Growth Fund, Inc. \| 2026

FUND INVESTMENT OBJECTIVE, STRATEGIES, POLICIES AND PRINCIPAL RISKS (continued)

(Unaudited)

Fund’s investments in debt instruments. In general, the longer the maturity or duration of a debt instrument, the greater its sensitivity to changes in interest rates. For example, a three-year duration means a bond is expected to decrease in value by 3% if interest rates rise 1% and increase in value by 3% if interest rates fall 1%. Interest rate declines also may increase prepayments of debt obligations, which, in turn, would increase prepayment risk (the risk that the Fund will have to reinvest the money received in securities that have lower yields). The Fund is subject to the risk that the income generated by its investments may not keep pace with inflation. Actions by governments and central banking authorities can result in increases or decreases in interest rates. Higher periods of inflation could lead such authorities to raise interest rates. Such actions may negatively affect the value of debt instruments held by the Fund, resulting in a negative impact on the Fund’s performance and NAV. Any interest rate increases could cause the value of the Fund’s investments in debt instruments to decrease.

Issuer Risk.

An issuer in which the Fund invests or to which it has exposure may perform poorly or below expectations and the value of its securities may therefore decline, which may negatively affect the Fund’s performance. Underperformance of an issuer may be caused by poor management decisions, competitive pressures, breakthroughs in technology, reliance on suppliers, labor problems or shortages, corporate restructurings, fraudulent disclosures, natural disasters, military confrontations and actions, war, other conflicts, terrorism, disease/virus outbreaks, epidemics or other events, conditions and factors which may impair the value of your investment in the Fund and could result in a greater premium or discount between the market price and the NAV of the Fund’s shares and/or wider bid/ask spreads than those experienced by other

closed-end

funds.

Small- and

Mid-Cap

Stock Risk.

Securities of small- and

mid-cap

companies can, in certain circumstances, have a higher potential for gains than securities of larger companies but are more likely to have more risk than larger companies. For example, small- and

mid-cap

companies may be more vulnerable to market downturns and adverse business or economic events than larger companies because they may have more limited financial resources and business operations. Small- and

mid-cap

companies are also more likely than larger companies to have more limited product lines and operating histories and to depend on smaller and generally less experienced management teams. Securities of small- and

mid-cap

companies may trade less frequently and in smaller volumes and may be less liquid and fluctuate more sharply in value than securities of larger companies. When the Fund takes significant positions in small- and

mid-cap

companies with limited trading volumes, the liquidation of those positions, particularly in a distressed market, could be prolonged and result in Fund investment losses that would affect the value of your investment in the Fund. In addition, some small- and

mid-cap

companies may not be widely followed by the investment community, which can lower the demand for their stocks.

Large-Cap

Stock Risk.

Investments in larger, more established companies (larger companies), may involve certain risks associated with their larger size. For instance, larger companies may be less able to respond quickly to new competitive challenges, such as changes in consumer tastes or innovation from smaller competitors. Also, larger companies are sometimes less able to achieve as high growth rates as successful smaller companies, especially during extended periods of economic expansion.

Market Risk.

The Fund may incur losses due to declines in the value of one or more securities in which it invests. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally. In addition, turbulence in financial markets and reduced liquidity in equity, credit and/or fixed income markets may negatively affect many issuers, which could adversely affect the Fund’s ability to price or value

hard-to-value

assets in thinly traded and closed markets and could cause operational challenges. Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, other conflicts, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions and could result in a greater premium or discount between the market price and the NAV of the Fund’s shares and/or wider bid/ask spreads than those experienced by other

closed-end

funds.

FUND INVESTMENT OBJECTIVE, STRATEGIES, POLICIES AND PRINCIPAL RISKS (continued)

(Unaudited)

Market Trading Discount Risk.

The Fund’s Common Shares can and have traded at a discount to the Fund’s NAV. The shares of

closed-end

management investment companies frequently trade at a discount from their NAV. This is a risk separate and distinct from the risk that the Fund’s NAV may decrease.

Non-Diversified

Fund Risk.

The Fund is

non-diversified,

which generally means that it may invest a greater percentage of its total assets in the securities of fewer issuers than a “diversified” fund. This increases the risk that a change in the value of any one investment held by the Fund could affect the overall value of the Fund more than it would affect that of a diversified fund holding a greater number of investments. Accordingly, the Fund’s value will likely be more volatile than the value of a more diversified fund.

Offering Risk.

The provisions of the 1940 Act generally require that the public offering price of an investment company’s common shares (less any underwriting commissions and discounts) must equal or exceed the NAV per share of an investment company’s common stock (calculated within 48 hours of pricing), plus any sales commission charged in connection with the offering. In the offering described in the Fund’s current Prospectus, the Fund may, subject to market conditions, raise additional equity capital by issuing new Common Shares from time to time in varying amounts at a net price at or above the Fund’s NAV per Common Share (calculated within 48 hours of pricing). To the extent that Fund Common Shares do not trade at a premium, the Fund may be unable to issue additional Common Shares, and may incur costs associated with maintaining an “at the market” program without the potential benefits. The offering described in the Fund’s Prospectus may allow the Fund to pursue additional investment opportunities without the need to sell existing portfolio investments and will increase the asset size of the Fund and thus cause the Fund’s fixed expenses to be spread over a larger asset base. However, the issuance may not necessarily result in an increase to net income for stockholders, which depends upon available investment opportunities and other factors. The Fund cannot predict whether its Common Shares will trade in the future at a premium to Fund NAV per Common Share. Shares of common stock of

closed-end

investment companies frequently trade at a discount from NAV, which may increase investors’ risk of loss. In no event will Common Shares be issued at a price below the Fund’s NAV per Common Share (calculated within 48 hours of pricing) plus any sales commission charged in connection with the offering. The offering described in the Fund’s Prospectus entails potential risks to existing common stockholders. Although the issuance of additional Common Shares may facilitate a more active market in the Fund’s Common Shares by increasing the amount of Common Shares outstanding, the issuance of additional Common Shares may also have an adverse effect on prices for the Fund’s Common Shares in the secondary market by increasing the supply of Common Shares available for sale. The issuance of additional Common Shares will dilute the voting power of already outstanding Common Shares.

Secondary Market for the Common Shares Risk.

The issuance of Common Shares through the Fund’s Prospectus offering may have an adverse effect on the secondary market for the Common Shares. The increase in the amount of the Fund’s outstanding Common Shares resulting from this offering may put downward pressure on the market price for the Common Shares of the Fund. Common Shares will not be issued pursuant to the offering at any time when Common Shares are trading at a price lower than a price equal to the Fund’s NAV per Common Share plus the per Common Share amount of commissions. The Fund also issues Common Shares of the Fund through its Dividend Investment Plan. See “Dividend Investment Plan” in the Fund’s Prospectus. Common Shares may be issued under the plan at a discount to the market price for such Common Shares, which may put downward pressure on the market price for Common Shares of the Fund. When the Common Shares are trading at a premium, the Fund may also issue Common Shares of the Fund that are sold through transactions effected on the NYSE. The increase in the amount of the Fund’s outstanding Common Shares resulting from that offering may also put downward pressure on the market price for the Common Shares of the Fund. The voting power of current Common Stockholders will be diluted to the extent that such stockholders do not purchase shares in any future Common Share offerings or do not purchase sufficient shares to maintain their percentage interest. In addition, if the Investment Manager is unable to invest the proceeds of such offering as intended, the Fund’s per share distribution may decrease (or may consist of return of capital) and the Fund may not participate in market advances to the same extent as if such proceeds were fully invested as planned.

Sector Risk.

At times, the Fund may have a significant portion of its assets invested in securities of companies conducting business in a related group of industries within one or more economic sectors, including the communication services sector and information technology sector. Companies in the same sector may be similarly affected by economic, regulatory, political or market events or conditions, which may make the Fund vulnerable to unfavorable developments in that group of industries or economic sector.


10		Columbia Seligman Premium Technology Growth Fund, Inc. \| 2026

FUND INVESTMENT OBJECTIVE, STRATEGIES, POLICIES AND PRINCIPAL RISKS (continued)

(Unaudited)

Communication Services Sector and Information Technology Sector.

The Fund is vulnerable to the particular risks that may affect companies in the communication services sector and the information technology sector. Companies in these sectors are subject to certain risks, including the risk that new services, equipment or technologies will not be accepted by consumers and businesses or will become rapidly obsolete. Performance of such companies may be affected by factors including obtaining and protecting patents (or the failure to do so) and significant competitive pressures, including aggressive pricing of their products or services, new market entrants, competition for market share and short product cycles due to an accelerated rate of technological developments. Such competitive pressures may lead to limited earnings and/or falling profit margins. As a result, the value of their securities may fall or fail to rise. In addition, many communication services sector and information technology sector companies have limited operating histories and prices of these companies’ securities historically have been more volatile than other securities, especially over the short term. Some companies in these sectors are facing increased government and regulatory scrutiny and may be subject to adverse government or regulatory action, which could negatively impact the value of their securities.

Semiconductor and Semiconductor Equipment Industry Risk.

The Fund’s investment in the semiconductor and semiconductor equipment industry subjects the Fund to the risks of investments in the industry, including: intense competition, both domestically and internationally, including competition from subsidized foreign competitors with lower production costs; wide fluctuations in securities prices due to risks of rapid obsolescence of products and related technology; economic performance of the customers of semiconductor and related companies; their research costs and the risks that their products may not prove commercially successful; and thin capitalization and limited product lines, markets, financial resources or quality management and personnel. Semiconductor design and process methodologies are subject to rapid technological change requiring large expenditures, potentially requiring financing that may be difficult or impossible to obtain, for research and development in order to improve product performance and increase manufacturing yields. These companies rely on a combination of patents, trade secret laws and contractual provisions to protect their technologies. The process of seeking patent protection can be long and expensive. The industry is characterized by frequent litigation regarding patent and other intellectual property rights, which may require such companies to defend against competitors’ assertions of intellectual property infringement or misappropriation. Some companies are also engaged in other lines of business unrelated to the semiconductor business, and these companies may experience problems with these lines of business that could adversely affect their operating results. The international operations of many companies expose them to the risks associated with instability and changes in economic and political conditions, foreign currency fluctuations, changes in foreign regulations, tariffs, and trade disputes. Business conditions in this industry can change rapidly from periods of strong demand to periods of weak demand. Any future downturn in the industry could harm the business and operating results of these companies. The stock prices of companies in the industry have been and will likely continue to be volatile relative to the overall market.

Transactions in Derivatives.

The Fund may enter into derivative transactions or otherwise have exposure to derivative transactions through underlying investments. Derivatives are financial contracts whose values are, for example, based on (or “derived” from) traditional securities (such as a stock or bond), assets (such as a commodity like gold or a foreign currency), reference rates (such as the Secured Overnight Financing Rate (commonly known as SOFR)) or market indices (such as the Standard & Poor’s 500

Index). The use of derivatives is a highly specialized activity which involves investment techniques and risks different from those associated with ordinary portfolio securities transactions. Derivatives involve special risks and may result in losses or may limit the Fund’s potential gain from favorable market movements. Derivative strategies often involve leverage, which may exaggerate a loss, potentially causing the Fund to lose more money than it would have lost had it invested in the underlying security or other asset directly. The values of derivatives may move in unexpected ways, especially in unusual market conditions, and may result in increased volatility in the value of the derivative and/or the Fund’s shares, among other consequences. The use of derivatives may also increase the amount of taxes payable by stockholders holding shares in a taxable account. See the Taxation section in the Fund’s Statement of Additional Information for more information. Other risks arise from the Fund’s potential inability to terminate or to sell derivative


Columbia Seligman Premium Technology Growth Fund, Inc. \| 2026			11

FUND INVESTMENT OBJECTIVE, STRATEGIES, POLICIES AND PRINCIPAL RISKS (continued)

(Unaudited)

positions. A liquid secondary market may not always exist for the Fund’s derivative positions at times when the Fund might wish to terminate or to sell such positions.

Over-the-counter

instruments (investments not traded on an exchange) may be illiquid, and transactions in derivatives traded in the

over-the-counter

market are subject to the risk that the other party will not meet its obligations. The use of derivatives also involves the risks of mispricing or improper valuation and that changes in the value of the derivative may not correlate perfectly with the underlying security, asset, reference rate or index. The Fund also may not be able to find a suitable derivative transaction counterparty, and thus may be unable to engage in derivative transactions when it is deemed favorable to do so, or at all. The U.S. government and the European Union (and some other jurisdictions) have enacted regulations and similar requirements that prescribe clearing, margin, reporting and registration requirements for participants in the derivatives market. These requirements are evolving and their ultimate impact on the Fund remains unclear, but such impact could include restricting and/or imposing significant costs or other burdens upon the Fund’s participation in derivatives transactions. Additionally regulations governing the use of derivatives by registered investment companies, such as the Fund require, among other things, that a fund that invests in derivative instruments beyond a specified limited amount apply a

value-at-risk-based

limit to its portfolio and establish a comprehensive derivatives risk management program. As of the date of this report, the Fund is required to maintain a comprehensive derivatives risk management program. For more information on the risks of derivative investments and strategies, see the Statement of Additional Information.

FEES AND EXPENSES AND SHARE PRICE DATA

June 30, 2026 (Unaudited)

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy, hold and sell Common Shares. You may pay other fees, such as brokerage commissions and other fees to financial intermediaries, which are not reflected in the tables and examples below.


Stockholder Transaction Expenses
Dividend Investment Plan and Stock Repurchase Program Fees		None (a)


Annual Expenses (as a percentage of net assets attributable to common shares)
Management fees (b)	1.06	%
Other expenses	0.06	%
Acquired fund fees and expenses	0.00	%

Total Annual Expenses (c)	1.12	%

(a)

There are no service or brokerage charges to participants in the dividend investment plan; however, the Fund reserves the right to amend the plan to include a service charge payable to the Fund by the participants. The Fund reserves the right to amend the plan to provide for payment of brokerage fees by the plan participants in the event the plan is changed to provide for open market purchases of Fund Common Stock on behalf of plan participants. You will pay brokerage charges if you direct your broker or the plan agent to sell your Common Shares that you acquired pursuant to this plan. The expenses of administering the Fund’s Dividend Investment Plan and Stock Repurchase Program are included in “Other Expenses” of the Fund. You may also pay a pro rata share of brokerage commissions incurred in connection with open-market purchases pursuant to the Fund’s Stock Repurchase Program.

(b)

The Fund’s management fee is 1.06% of the Fund’s average daily Managed Assets (which means the net asset value of Fund’s outstanding common stock plus the liquidation preference of any issued and outstanding preferred stock of the Fund and the principal amount of any borrowing used for leverage). The management fee rate noted in the table reflects the rate paid by Common Stockholders as a percentage of the Fund’s net assets attributable to Common Stock. As of the date of this report, the Fund has not issued securities other than Common Shares.

(c)

“Total Annual Expenses” include acquired fund fees and expenses (expenses the Fund incurs indirectly through its investments in other investment companies) and may be higher than “Total gross expenses” shown in the

Financial Highlights

section of this report because “Total gross expenses” does not include acquired fund fees and expenses.

Example

The following example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The example illustrates the hypothetical expenses that you would incur over the time periods indicated, and assumes that:

•

you invest $1,000 in the Fund for the periods indicated,

•

your investment has a 5% return each year, and

•

the Fund’s total annual operating expenses remain the same as shown in the Annual Fund Operating Expenses table above. Although your actual costs may be higher or lower, based on the assumptions listed above, your costs would be:


	1 year		3 years		5 years		10 years
Columbia Seligman Premium Technology Growth Fund, Inc. Common Stock	$	21	$	45	$	71	$	145

The purpose of the tables above is to assist you in understanding the various costs and expenses you will bear directly or indirectly.

Fair value measurements

The Fund categorizes its fair value measurements according to a three-level hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs by prioritizing that the most observable input be used when available. Observable inputs are those that market participants would use in pricing an investment based on market data obtained from sources independent of the reporting entity. Unobservable inputs are those that reflect the Fund’s assumptions about the information market participants would use in pricing an investment. An investment’s level within the fair value hierarchy is based on the lowest level of any input that is deemed significant to the asset’s or liability’s fair value measurement. The input levels are not necessarily an indication of the risk or liquidity associated with investments at that level. For example, certain U.S. government securities are generally high quality and liquid, however, they are reflected as Level 2 because the inputs used to determine fair value may not always be quoted prices in an active market.

Fair value inputs are summarized in the three broad levels listed below:

•

Level 1 — Valuations based on quoted prices for investments in active markets that the Fund has the ability to access at the measurement date. Valuation adjustments are not applied to Level 1 investments.

•

Level 2 — Valuations based on other significant observable inputs (including quoted prices for similar securities, interest rates, prepayment speeds, credit risks, etc.).

•

Level 3 — Valuations based on significant unobservable inputs (including the Fund’s own assumptions and judgment in determining the fair value of investments).

Inputs that are used in determining fair value of an investment may include price information, credit data, volatility statistics, and other factors. These inputs can be either observable or unobservable. The availability of observable inputs can vary between investments, and is affected by various factors such as the type of investment, and the volume and level of activity for that investment or similar investments in the marketplace. The inputs will be considered by Columbia Management Investment Advisers, LLC (the Investment Manager), along with any other relevant factors in the calculation of an investment’s fair value. The Fund uses prices and inputs that are current as of the measurement date, which may include periods of market dislocations. During these periods, the availability of prices and inputs may be reduced for many investments. This condition could cause an investment to be reclassified between the various levels within the hierarchy.

Values of foreign equity securities actively traded in markets where there is a significant delay in the local close relative to the New York Stock Exchange may include an adjustment to reflect the impact of market movements following the close of local trading, as described in Note 2 to the financial statements – Security valuation. When such adjustments have been made, the foreign equity securities are classified as Level 2.

Investments falling into the Level 3 category, if any, are primarily supported by quoted prices from brokers and dealers participating in the market for those investments. However, these may be classified as Level 3 investments due to lack of market transparency and corroboration to support these quoted prices. Additionally, valuation models may be used as the pricing source for any remaining investments classified as Level 3. These models may rely on one or more significant unobservable inputs and/ or significant assumptions by the Investment Manager. Inputs used in valuations may include, but are not limited to, financial statement analysis, capital account balances, discount rates and estimated cash flows, and comparable company data.

The Fund’s Board of Directors (the Board) has designated the Investment Manager, through its Valuation Committee (the Committee), as valuation designee, responsible for determining the fair value of the assets of the Fund for which market quotations are not readily available using valuation procedures approved by the Board. The Committee consists of voting and

non-voting

members from various groups within the Investment Manager’s organization, including operations and accounting, trading and investments, compliance, risk management and legal.

The Committee meets at least monthly to review and approve valuation matters, which may include a description of specific valuation determinations, data regarding pricing information received from approved pricing vendors and brokers and the results of Board-approved valuation policies and procedures (the Policies). The Policies address, among other things, instances when market quotations are or are not readily available, including recommendations of third party pricing vendors and a determination of appropriate pricing methodologies; events that require specific valuation determinations and assessment of fair value techniques; securities with a potential for stale pricing, including those that are illiquid, restricted, or in default; and the effectiveness of third party pricing vendors, including periodic reviews of vendors. The Committee meets more frequently, as needed, to discuss additional valuation matters, which may include the need to review back-testing results, review timesensitive information or approve related valuation actions. Representatives of the Investment Manager report to the Board at each of its regularly scheduled meetings to discuss valuation matters and actions during the period, similar to those described earlier.

The Fund’s assets assigned to the Level 2 input category are generally valued using the market approach, in which a security’s value is determined through reference to prices and information from market transactions for similar or identical assets. These assets include certain foreign securities for which a third party statistical pricing service may be employed for purposes of fair market valuation. The model utilized by such third party statistical pricing service takes into account a security’s correlation to available market data including relevant general and sector indices, currency fluctuations, depositary receipts, and futures, as applicable.

FINANCIAL HIGHLIGHTS

The Fund’s financial highlights are presented below. Per share operating performance data is designed to allow investors to trace the operating performance, on a per Common Stock share basis, from the beginning net asset value to the ending net asset value, so that investors can understand what effect the individual items have on their investment, assuming it was held throughout the period. Generally, the per share amounts are derived by converting the actual dollar amounts incurred for each item, as disclosed in the financial statements, to their equivalent per Common Stock share amounts, using average Common Stock shares outstanding during the period.

Total return measures the Fund’s performance assuming that investors purchased Fund shares at market price or net asset value as of the beginning of the period, reinvested all their distributions, and then sold their shares at the closing market price or net asset value on the last day of the period. The computations do not reflect taxes or any sales commissions investors may incur on distributions or on the sale of Fund shares. Total returns and portfolio turnover are not annualized for periods of less than one year. The ratios of expenses and net investment income are annualized for periods of less than one year. The portfolio turnover rate is calculated without regard to purchase and sales transactions of short-term instruments and certain derivatives, if any. If such transactions were included, a Fund’s portfolio turnover rate may be higher. A zero balance may reflect an amount rounding to less than $0.01 or 0.01%.

NOTES TO FINANCIAL STATEMENTS

June 30, 2026 (Unaudited)

Note 1. Organization

Columbia Seligman Premium Technology Growth Fund, Inc. (the Fund) is a

non-diversified

fund. The Fund is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as a

closed-end

management investment company.

The Fund was incorporated under the laws of the State of Maryland on September 3, 2009, and commenced investment operations on November 30, 2009. The Fund had no investment operations prior to November 30, 2009 other than those relating to organizational matters and the sale to Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), of 5,250 shares of Common Stock at a cost of $100,275 on October 14, 2009. As of December 31, 2009, the Fund issued 14,300,000 shares of Common Stock, including 13,100,000 shares of Common Stock in its initial public offering and 1,200,000 shares of Common Stock purchased by the Fund’s underwriters pursuant to an over-allotment option granted to the underwriters in connection with the initial public offering. On January 13, 2010, the Fund’s underwriters purchased an additional 545,000 shares of Common Stock pursuant to the over-allotment option, resulting in a total of 14,845,000 shares of Common Stock issued by the Fund in its initial public offering, including shares purchased by the underwriters pursuant to the over-allotment option. With the closing of this additional purchase of Common Stock, the Fund’s total

raise-up

in its initial public offering was an aggregate of $296.9 million. The Fund has one billion authorized shares of Common Stock. The issued and outstanding Common Stock trades on the New York Stock Exchange under the symbol “STK”.

On June 26, 2024, the Fund filed a registration statement on Form

N-2

(File

No. 333-280485)

with the Securities and Exchange Commission (the SEC), relating to the offer and sale of up to 8,000,000 shares of Fund Common Stock, from time to time, through ALPS Distributors, Inc., as agent for the Fund (the Distributor), in transactions that are deemed to be

“at-the-market”

as defined in Rule 415 under the Securities Act of 1933, as amended. On November 15, 2024, the SEC declared this registration statement to be effective. Offering costs of the registration were paid by the Investment Manager and therefore are not included in the fees or expenses of the Fund. With respect to the Fund’s

at-the-market

offering, the Fund compensates the Distributor with respect to sales of the Common Stock at a commission rate of up to 1.0% of the gross proceeds of the sale of Common Stock. The Distributor may enter into

sub-placement

agent agreements with one or more selected dealers for the offer and sale of Common Stock under the Fund’s

at-the-market

offering. In that regard, the Distributor entered into a

sub-placement

agreement with UBS Securities LLC.

The Fund currently has outstanding Common Stock. Each outstanding share of Common Stock entitles the holder thereof to one vote on all matters submitted to a vote of the Common Stockholders, including the election of directors. Because the Fund has no other classes or series of stock outstanding, Common Stock possesses exclusive voting power. All of the Fund’s shares of Common Stock have equal dividend, liquidation, voting and other rights. The Fund’s Common Stockholders have no preference, conversion, redemption, exchange, sinking fund, or appraisal rights and have no preemptive rights to subscribe for any of the Fund’s securities.

Although the Fund has no current intention to do so, the Fund is authorized and reserves the flexibility to use leverage to increase its investments or for other management activities through the issuance of Preferred Stock and/or borrowings. The costs of issuing Preferred Stock and/or a borrowing program would be borne by Common Stockholders and consequently would result in a reduction of net asset value of Common Stock.

Note 2. Summary of significant accounting policies

Basis of preparation

The Fund is an investment company that applies the accounting and reporting guidance in the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946,

Financial Services - Investment Companies (ASC 946)

. The financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP), which require management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from those estimates.

NOTES TO FINANCIAL STATEMENTS (continued)

June 30, 2026 (Unaudited)

The following is a summary of significant accounting policies followed by the Fund in the preparation of its financial statements.

Segment reporting

The intent of FASB Accounting Standards Update

2023-07,

Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures is to enable investors to better understand an entity’s overall performance and to assess its potential future cash flows through improved segment disclosures. The chief operating decision maker (CODM) for the Fund is Columbia Management Investment Advisers, LLC through its Investment Oversight Committee and Global Executive Group, which are responsible for assessing performance and making decisions about resource allocation. The CODM has determined that the Fund has a single operating segment because the CODM monitors the operating results of the Fund as a whole and the Fund’s long-term strategic asset allocation is

pre-determined

in accordance with the terms of its prospectus, based on a defined investment strategy which is executed by the Fund’s portfolio managers as a team. The financial information provided to and reviewed by the CODM is consistent with that presented within the Fund’s financial statements.

Security valuation

Equity securities listed on an exchange are valued at the closing price or last trade price on their primary exchange at the close of business of the New York Stock Exchange. Securities with a closing price not readily available or not listed on any exchange are valued at the mean between the closing bid and ask prices. Listed preferred stocks convertible into common stocks are valued using an evaluated price from a pricing service.

Foreign equity securities are valued based on the closing price or last trade price on their primary exchange at the close of business of the New York Stock Exchange. If any foreign equity security closing prices are not readily available, the securities are valued at the mean of the latest quoted bid and ask prices on such exchanges or markets. Foreign currency exchange rates are determined at the scheduled closing time of the New York Stock Exchange. Many securities markets and exchanges outside the U.S. close prior to the close of the New York Stock Exchange; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after such close but before the close of the New York Stock Exchange. In those situations, foreign securities will be fair valued pursuant to a policy approved by the Board of Directors. Under the policy, the Fund may utilize a third-party pricing service to determine these fair values. The third-party pricing service takes into account multiple factors, including relevant general and sector indices, currency fluctuations, depositary receipts, and futures, as applicable, to determine a good faith estimate that reasonably reflects the current market conditions as of the close of the New York Stock Exchange. The fair value of a security is likely to be different from the quoted or published price, if available.

Investments in

open-end

investment companies (other than exchange-traded funds (ETFs)) are valued at the latest net asset value reported by those companies as of the valuation time.

Option contracts are valued at the mean of the latest quoted bid and ask prices on their primary exchanges. Option contracts, including

over-the-counter

option contracts, with no readily available market quotations are valued using midmarket evaluations from independent third-party vendors.

Investments for which market quotations are not readily available, or that have quotations which management believes are not reflective of market value or reliable, are valued at fair value as determined in good faith under procedures approved by the Board of Directors. If a security or class of securities (such as foreign securities) is valued at fair value, such value is likely to be different from the quoted or published price for the security, if available.

The determination of fair value often requires significant judgment. To determine fair value, management may use assumptions including but not limited to future cash flows and estimated risk premiums. Multiple inputs from various sources may be used to determine fair value.

GAAP requires disclosure regarding the inputs and valuation techniques used to measure fair value and any changes in valuation inputs or techniques. In addition, investments shall be disclosed by major category. This information is disclosed following the Fund’s Portfolio of Investments.

NOTES TO FINANCIAL STATEMENTS (continued)

Foreign currency transactions and translations

The values of all assets and liabilities denominated in foreign currencies are generally translated into U.S. dollars at exchange rates determined at the close of regular trading on the New York Stock Exchange. Net realized and unrealized gains (losses) on foreign currency transactions and translations include gains (losses) arising from the fluctuation in exchange rates between trade and settlement dates on securities transactions, gains (losses) arising from the disposition of foreign currency and currency gains (losses) between the accrual and payment dates on dividends, interest income and foreign withholding taxes.

For financial statement purposes, the Fund does not distinguish that portion of gains (losses) on investments which is due to changes in foreign exchange rates from that which is due to changes in market prices of the investments. Such fluctuations are included with the net realized and unrealized gains (losses) on investments in the Statement of Operations.

Derivative instruments

The Fund may invest in certain derivative instruments, which are transactions whose values depend on or are derived from (in whole or in part) the value of one or more other assets, such as securities, currencies, commodities or indices. The Fund uses a rules-based call option writing strategy on the NASDAQ 100 Index

, an unmanaged index that includes the largest and most active nonfinancial domestic and international companies listed on the Nasdaq Stock Market, or its exchange-traded fund equivalent (NASDAQ 100) on a

month-to-month

basis.

The Fund may also seek to provide downside protection by purchasing puts on the NASDAQ 100 when premiums on these options are considered by the Investment Manager to be low and, therefore, attractive relative to the downside protection provided.

The Fund may also buy or write other call and put options on securities, indices, ETFs and market baskets of securities to generate additional income or return or to provide the portfolio with downside protection. In this regard, options may include writing

“in-”

“out-of-the-money”

put options or buying or selling options in connection with closing out positions prior to expiration of any options. However, the Fund does not intend to write “naked” call options on individual stocks (i.e., selling a call option on an individual security not owned by the Fund) other than in connection with implementing the options strategies with respect to the NASDAQ 100. The put and call options purchased, sold or written by the Fund may be exchange-listed or

over-the-counter.

The notional exposure of a financial instrument is the nominal or face amount that is used to calculate payments made on that instrument and/or changes in value for the instrument. The notional exposure is a hypothetical underlying quantity upon which payment obligations are computed. Notional exposures provide a gauge for how the Fund may behave given changes in the underlying rate, asset or reference instrument and individual markets. The notional amounts of derivative instruments, if applicable, are not recorded in the financial statements. A derivative instrument may suffer a mark to market loss if the value of the contract decreases due to an unfavorable change in the market rates or values of the underlying instrument. Losses can also occur if the counterparty does not perform under the contract. Options written by the Fund do not typically give rise to counterparty credit risk, as options written generally obligate the Fund and not the counterparty to perform. With exchange-traded purchased options, there is less counterparty credit risk to the Fund than in the case of an

over-the-counter

derivative, since the exchange’s clearinghouse, as counterparty to such instruments, provides some protection in the case of clearing member default. The clearinghouse stands between the buyer and the seller of the contract; therefore, the primary counterparty credit risk is the risk of failure of the clearinghouse. However, credit risk still exists in exchange traded or cleared derivatives with respect to any collateral that is held in a broker’s customer accounts. While clearing brokers are required to segregate customer collateral from their own assets, in the event that a clearing broker becomes insolvent or goes into bankruptcy and at that time there is a shortfall in the aggregate amount of collateral held by the broker for all its clients, U.S. bankruptcy laws will typically allocate that shortfall on a

pro-rata

basis across all the clearing broker’s customers (including the Fund) by account class, potentially resulting in losses to the Fund.

In connection with certain

over-the-counter

derivatives, the Fund may enter into an International Swaps and Derivatives Association, Inc. Master Agreement (ISDA Master Agreement) or similar agreement with its derivatives counterparties. An ISDA Master Agreement is a bilateral agreement between a Fund and a counterparty that governs

over-the-counter


28		Columbia Seligman Premium Technology Growth Fund, Inc. \| 2026

NOTES TO FINANCIAL STATEMENTS (continued)

June 30, 2026 (Unaudited)

derivatives and forward foreign exchange contracts and contains, among other things, collateral posting terms and netting provisions in the event of a default and/or termination event. Under an ISDA Master Agreement, the Fund may, under certain circumstances, offset with the counterparty certain derivative financial instrument’s payables and/or receivables with collateral held and/or posted and create one single net payment. The provisions of the ISDA Master Agreement typically permit a single net payment in the event of default

(close-out

netting) including the bankruptcy or insolvency of the counterparty. Note, however, that bankruptcy or insolvency laws of a particular jurisdiction may impose restrictions on or prohibitions against the right of offset in bankruptcy, insolvency or other events. Collateral (margin) requirements differ by type of derivative. Collateral terms for most

over-the-counter

derivatives are subject to regulatory requirements to exchange variation margin with trading counterparties and may have contract specific margin terms as well. Margin requirements are established by the exchange for exchange traded options and by the CCP for futures and options on futures. Brokers can ask for margin in excess of the minimum in certain circumstances. To the extent amounts due to the Fund from its counterparties are not fully collateralized, contractually or otherwise, the Fund bears the risk of loss from counterparty nonperformance. The Fund may also pay interest expense on cash collateral received from the broker or receive interest income on cash collateral pledged to the broker. The Fund attempts to mitigate counterparty risk by only entering into agreements with counterparties that it believes have the financial resources to honor their obligations and by monitoring the financial stability of those counterparties.

Investments in derivative instruments may expose the Fund to certain additional risks, including those detailed below.

Options contracts

Options are contracts which entitle the holder to purchase or sell securities or other identified assets at a specified price, or in the case of index option contracts, to receive or pay the difference between the index value and the strike price of the index option contract. Option contracts can be either exchange-traded or

over-the-counter.

The Fund may use options that are written or purchased to enhance returns or to hedge an existing position or future investment. A Fund may write call and put options on securities and financial derivative instruments it owns or in which it may invest. Writing put options tends to increase a Fund’s exposure to the underlying instrument. Writing call options tends to decrease a Fund’s exposure to the underlying instrument. When a Fund writes a call or put, an amount equal to the premium received is recorded and subsequently marked to market to reflect the current value of the option written. These instruments may be used for other purposes in future periods. Completion of transactions for option contracts traded in the

over-the-counter

market depends upon the performance of the other party. Collateral may be collected or posted by the Fund to secure

over-the-counter

option contract trades. Collateral held or posted by the Fund for such option contract trades must be returned to the broker or the Fund upon closure, exercise or expiration of the contract.

Option contracts purchased are recorded as investments. When a Fund writes an options contract, the premium received is recorded as an asset and an amount equivalent to the premium is recorded as a liability in the Statement of Assets and Liabilities and is subsequently adjusted to reflect the current fair value of the option written. Changes in the fair value of the written option are recorded as unrealized appreciation or depreciation until the contract is exercised or has expired. A Fund realizes a gain or loss when the option contract is closed or expires. When option contracts are exercised, the proceeds on sales for a written call or purchased put option contract, or the purchase cost for a written put or purchased call option contract, is adjusted by the amount of premium received or paid.

For

over-the-counter

options purchased, a Fund bears the risk of loss of the amount of the premiums paid plus the positive change in market values net of any collateral held by a Fund should the counterparty fail to perform under the contracts. Option contracts written by a Fund do not typically give rise to significant counterparty credit risk, as options written generally obligate a Fund and not the counterparty to perform. The risk in writing a call option contract is that a Fund gives up the opportunity for profit if the market price of the security increases above the strike price and the option contract is exercised. The risk in writing a put option contract is that a Fund may incur a loss if the market price of the security decreases below the strike price and the option contract is exercised. Exercise of a written option could result in the Fund purchasing or selling a security or foreign currency when it otherwise would not, or at a price different from the current market value. In purchasing and writing options, the Fund bears the risk of an unfavorable change in the value of the underlying instrument or the risk that the Fund may not be able to enter into a closing transaction due to an illiquid market.

NOTES TO FINANCIAL STATEMENTS (continued)

June 30, 2026 (Unaudited)

Security transactions

Security transactions are accounted for on the trade date. Cost is determined and gains (losses) are based upon the specific identification method for both financial statement and federal income tax purposes.

Income recognition

Corporate actions and dividend income are generally recorded net of any

non-reclaimable

tax withholdings, on the ex-dividend date or upon receipt of an

ex-dividend

notification in the case of certain foreign securities.

Awards from class action litigation are recorded as a reduction of cost basis if the Fund still owns the applicable securities on the payment date. If the Fund no longer owns the applicable securities on the payment date, the proceeds are recorded as realized gains.

The Fund may receive distributions from holdings in equity securities, business development companies (BDCs), exchange-traded funds (ETFs), limited partnerships (LPs), other regulated investment companies (RICs), and real estate investment trusts (REITs), which report information as to the tax character of their distributions annually. These distributions are allocated to dividend income, capital gain and return of capital based on actual information reported. Return of capital is recorded as a reduction of the cost basis of securities held. If the Fund no longer owns the applicable securities, return of capital is recorded as a realized gain. With respect to REITs, to the extent actual information has not yet been reported, estimates for return of capital are made by Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). The Investment Manager’s estimates are subsequently adjusted when the actual character of the distributions is disclosed by the REITs, which could result in a proportionate change in return of capital to stockholders.

Determination of net asset value

The net asset value per share of the Fund is computed by dividing the value of the net assets of the Fund by the total number of outstanding shares of the Fund, rounded to the nearest cent, at the close of regular trading (ordinarily 4:00 p.m. Eastern Time) every day the New York Stock Exchange is open.

Federal income tax status

The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Internal Revenue Code, as amended, and will distribute substantially all of its investment company taxable income and net capital gain, if any, for its tax year, and as such will not be subject to federal income taxes. In addition, the Fund intends to distribute in each calendar year substantially all of its ordinary income, capital gain net income and certain other amounts, if any, such that the Fund should not be subject to federal excise tax. Therefore, no federal income or excise tax provision is recorded.

Foreign taxes

The Fund may be subject to foreign taxes on income, gains on investments or currency repatriation, a portion of which may be recoverable. The Fund will accrue such taxes and recoveries, as applicable, based upon its current interpretation of tax rules and regulations that exist in the markets in which it invests.

Realized gains in certain countries may be subject to foreign taxes at the Fund level, based on statutory rates. The Fund accrues for such foreign taxes on realized and unrealized gains at the appropriate rate for each jurisdiction, as applicable. The amount, if any, is disclosed as a liability in the Statement of Assets and Liabilities.

Dividends to stockholders

In November 2010, the Fund paid its first dividend under the Fund’s managed distribution policy adopted by the Fund’s Board of Directors. 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 1940 Act, the Fund could not distribute long-term capital gains, as defined in the Internal Revenue Code of 1986, 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 distribute long-term capital gains more often than once in any one taxable year. After consideration by the Fund’s Board of Directors, the Fund


30		Columbia Seligman Premium Technology Growth Fund, Inc. \| 2026

NOTES TO FINANCIAL STATEMENTS (continued)

June 30, 2026 (Unaudited)

adopted the managed distribution policy which allows the Fund to make periodic distributions of long-term capital gains. Under its managed distribution policy, the Fund intends to make quarterly distributions to Common Stockholders at a rate that reflects the past and projected performance of the Fund. 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 a portion of an investor’s original investment. A return of capital is not taxable, but it reduces a Stockholder’s tax basis in his or her shares, thus reducing any loss or increasing any gain on a subsequent taxable disposition by the Stockholder of his or her shares. Distributions may vary, 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 described above. The net investment income of the Fund consists of all income (other than net short-term and long-term capital gains) less all expenses of the Fund.

The Board of Directors 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, as the Fund’s portfolio and market conditions change, 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. Over time, the Fund will distribute all of its net investment income and net short-term capital gains. In addition, at least annually, the Fund intends to distribute any net capital gain (which is the excess of net long-term capital gain over net short-term capital loss) or, alternatively, to retain all or a portion of the year’s net capital gain and pay federal income tax on the retained gain.

Dividends and other distributions to stockholders are recorded on

ex-dividend

dates.

The Fund has an investment objective to seek growth of capital and current income. In the latter regard, in 2025, the Fund’s managed distribution policy provided stockholders with current income through quarterly distributions of $0.4625 per share, comprised of $0.2082 in short-term capital gains and $1.6418 in long-term capital gains. In order to avoid federal excise tax in 2025, the Fund also paid a special fourth quarter capital gain distribution, beyond its typical quarterly managed distribution policy, in the amount of $0.8655 per share, comprised fully of long-term capital gains. No portion of the Fund’s 2025 distributions, including such special distribution, consisted of a return of capital. 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. The Fund was fully invested throughout 2025, implementing its technology and options investing strategies so as to position the Fund to achieve its capital appreciation investment objective, as evidenced by the Fund’s NAV return of 29.39% in 2025, which outperformed the Fund’s benchmark, the S&P North American Technology Sector Index’s return of 27.82% for the same period.

Guarantees and indemnifications

Under the Fund’s organizational documents and, in some cases, by contract, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the Fund. In addition, certain of the Fund’s contracts with its service providers contain general indemnification clauses. The Fund’s maximum exposure under these arrangements is unknown since the amount of any future claims that may be made against the Fund cannot be determined, and the Fund has no historical basis for predicting the likelihood of any such claims.

Note 3. Fees and other transactions with affiliates

Management services fees

The Fund has entered into a Management Agreement with Columbia Management Investment Advisers, LLC (the Investment Manager), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial). Under the Management Agreement, the Investment Manager provides the Fund with investment research and advice and is responsible for administrative and accounting services. The management services fee is payable as a percentage of the Fund’s daily Managed Assets that declines from 1.06% to 0.85% as the Fund’s Managed Assets increase. The annualized effective management services fee rate for the six months ended June 30, 2026, was 1.06% of the Fund’s average daily Managed Assets. “Managed Assets” means the net asset value of the Fund’s outstanding Common Stock plus the liquidation preference of any issued and outstanding preferred stock of the Fund and the principal amount of any borrowings used for leverage. To date, the Fund has not issued preferred stock and during the period there were no borrowings used for leverage.

June 30, 2026 (Unaudited)

Compensation of Board members

Members of the Board of Directors who are not officers or employees of the Investment Manager or Ameriprise Financial are compensated for their services to the Fund as disclosed in the Statement of Operations. Under a Deferred Compensation Plan (the Deferred Plan), these members of the Board of Directors may elect to defer payment of up to 100% of their compensation. Deferred amounts are treated as though equivalent dollar amounts had been invested in shares of certain funds managed by the Investment Manager. The Fund’s liability for these amounts is adjusted for market value changes and remains in the Fund until distributed in accordance with the Deferred Plan. All amounts payable under the Deferred Plan constitute a general unsecured obligation of the Fund. The expense for the Deferred Plan, which includes Directors’ fees deferred during the current period as well as any gains or losses on the Directors’ deferred compensation balances as a result of market fluctuations, is included in “Deferred compensation of board members” in the Statement of Operations.

Compensation of Chief Compliance Officer

The Board of Directors has appointed a Chief Compliance Officer for the Fund in accordance with federal securities regulations. As disclosed in the Statement of Operations, a portion of the Chief Compliance Officer’s total compensation is allocated to the Fund, along with other allocations to affiliated registered investment companies managed by the Investment Manager and its affiliates, based on relative net assets.

Note 4. Federal tax information

The timing and character of income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP because of temporary or permanent book to tax differences.

At June 30, 2026, the approximate cost of all investments for federal income tax purposes and the aggregate gross approximate unrealized appreciation and depreciation based on that cost was:


Tax cost ($)		Gross unrealized appreciation ($)		Gross unrealized (depreciation) ($)			Net unrealized appreciation ($)
	495,375,000		562,385,000		(42,563,000	)		519,822,000

Tax cost of investments and unrealized appreciation/(depreciation) may also include timing differences that do not constitute adjustments to tax basis.

Management of the Fund has concluded that there are no significant uncertain tax positions in the Fund that would require recognition in the financial statements. However, management’s conclusion may be subject to review and adjustment at a later date based on factors including, but not limited to, new tax laws, regulations, and administrative interpretations (including relevant court decisions). Generally, the Fund’s federal tax returns for the prior three fiscal years remain subject to examination by the Internal Revenue Service.

Note 5. Portfolio information

The cost of purchases and proceeds from sales of securities, excluding short-term investments and derivatives, for the six months ended June 30, 2026, were as follows:


Non-U.S. government purchases ($)		Non-U.S. government proceeds from sales ($)
249,926,557		327,609,968

The amount of purchase and sale activity impacts the portfolio turnover rate reported in the Financial Highlights.

NOTES TO FINANCIAL STATEMENTS (continued)

June 30, 2026 (Unaudited)

Note 6. Capital Stock Transactions

The Fund, in connection with its Dividend Investment Plan (the Plan), issues shares of its own Common Stock, as needed, to satisfy the Plan requirements. A total of 7,400 shares were issued to the Plan participants during the six months ended June 30, 2026, for proceeds of $323,658, a weighted average discount of (3.78)% from the net asset value of those shares.

Pursuant to the Plan, unless a Common Stockholder elects otherwise, all cash dividends, capital gains distributions, and other distributions are automatically reinvested in additional Common Stock. If you hold your shares in street name or other nominee (i.e., through a broker), you should contact them to determine their policy, as the broker firm’s policy with respect to Fund distributions may be to default to a cash payment. Common Stockholders who elect not to participate in the Plan (including those whose intermediaries do not permit participation in the Plan by their customers) will receive all dividends and distributions payable in cash directly to the Common Stockholder of record (or, if the shares of Common Stock are held in street or other nominee name, then to such nominee). Common Stockholders may elect not to participate in the Plan and to receive all distributions of dividends and capital gains or other distributions in cash by sending written instructions to Equiniti Trust Company, LLC (Equiniti), EQ Shareowner Services, Attn: OnBase, P.O. Box 500, Newark, NJ 07101. Participation in the Plan may be terminated or resumed at any time without penalty by written notice if received by Equiniti, prior to the record date for the next distribution. Otherwise, such termination or resumption will be effective with respect to any subsequently declared distribution. The income tax consequences of participation in the Plan are the same whether you participate in the Plan and reinvest your Fund distributions or you elect not to participate in the Plan and receive all your Fund distributions in cash (i.e., capital gains and income are realized, although cash is not received by the shareholder).

Under the Plan, Common Stockholders receive shares of Common Stock in lieu of cash distributions unless they have elected otherwise as described above. Common Stock will be issued in lieu of cash by the Fund from previously authorized but unissued Common Stock. If the market price of a share on the

ex-dividend

date of such a distribution is at or above the Fund’s net asset value per share on such date, the number of shares to be issued by the Fund to each Common Stockholder receiving shares in lieu of cash distributions will be determined by dividing the amount of the cash distribution to which such Common Stockholder would be entitled by the greater of the net asset value per share on such date or 95% of the market price of a share on such date. If the market price of a share on such an

ex-dividend

date is below the net asset value per share, the number of shares to be issued to such Common Stockholders will be determined by dividing such amount by the per share market price. The issuance of Common Stock at less than net asset value per share will dilute the net asset value of all Common Stock outstanding at that time. Market price on any day means the closing price for the Common Stock at the close of regular trading on the New York Stock Exchange on such day or, if such day is not a day on which the Common Stock trades, the closing price for the Common Stock at the close of regular trading on the immediately preceding day on which trading occurs.

The Fund reserves the right to amend or terminate the Plan as applied to any distribution paid subsequent to written notice of the change sent to participants in the Plan at least 90 days before the record date for such distribution. There are no service or brokerage charges to participants in the Plan; however, the Fund reserves the right to amend the Plan to include a service charge payable to the Fund by the participants. The Fund reserves the right to amend the Plan to provide for payment of brokerage fees by the Plan participants in the event the Plan is changed to provide for open market purchases of Common Stock on behalf of the Plan participants. All correspondence concerning the Plan should be directed to Equiniti.

The Fund has entered into the Distribution Agreement with ALPS Distributors, Inc. (the Distributor), pursuant to which the Fund may offer and sell up to 8,000,000 shares of Fund Common Stock, from time to time, through the Distributor, in transactions that are deemed to be

“at-the-market”

as defined in Rule 415 under the 1933 Act. There is no guarantee that there will be any sales of Common Stock pursuant to the Prospectus relating to this offering. There is no guarantee that the Fund will sell all of the Common Stock available for sale or that there will be any sales of Common Stock under this offering. The minimum price at which Common Stock may be sold will not be less than an amount at least equal to the then current NAV per share of Common Stock plus the per share of Common Stock amount of the commission to be paid to the Distributor (Minimum Price). The Fund along with the Distributor and the sub placement agent will not authorize sales of Common Stock if the price per share of the Common Stock is less than the Minimum Price. The Fund may elect not to authorize sales of Common Stock on a particular day even if the price per share of the Common Stock is equal to or greater than the Minimum Price or may only authorize a fixed number of shares of Common Stock to be sold on any particular day.


Columbia Seligman Premium Technology Growth Fund, Inc. \| 2026			33

NOTES TO FINANCIAL STATEMENTS (continued)

June 30, 2026 (Unaudited)

The Fund has full discretion regarding whether sales of shares of Common Stock will be authorized on a particular day and, if so, in what amounts. A total of 26,343 shares were issued under the

at-the-market

offering during the six months ended June 30, 2026, for proceeds of $1,479,229, a weighted average premium of 1.69% from the net asset value of those shares.

In September 2025, the Fund’s Board approved the Fund’s stock repurchase program. The Fund, under its stock repurchase program, currently intends to make open market purchases of its Common Stock from time to time when the Fund’s Common Stock is trading at a discount to its net asset value, in an amount approximately sufficient to offset the growth in the number of shares of Common Stock issued as a result of the reinvestment of the portion of its distributions to Common Stockholders that are attributable to distributions received by the Fund from its underlying portfolio investments less fund expenses; however, in order to facilitate the required distributions, no repurchases will be made during the period between the declaration date and the

ex-dividend

date for Fund distributions. For the six months ended June 30, 2026, no shares were purchased in the open market.

Note 7. Affiliated money market fund

The Fund invests in Columbia Short-Term Cash Fund, an affiliated money market fund established for the exclusive use by the Fund and other affiliated funds (the Affiliated MMF). The income earned by the Fund from such investments is included as Dividends - affiliated issuers in the Statement of Operations. As an investing fund, the Fund indirectly bears its proportionate share of the expenses of the Affiliated MMF. The Affiliated MMF prices its shares with a floating net asset value. The Securities and Exchange Commission has adopted amendments to money market fund rules requiring institutional prime money market funds like the Affiliated MMF to be subject to a discretionary liquidity fee of up to 2% if the imposition of such a fee is determined to be in the best interest of the Affiliated MMF and to a mandatory liquidity fee if daily net redemptions exceed 5% of net assets.

Note 8. Interfund Lending

Pursuant to an exemptive order granted by the Securities and Exchange Commission, the Fund entered into a master interfund lending agreement (the Interfund Program) with certain other funds advised by the Investment Manager or its affiliates (each a Participating Fund). The Interfund Program allows each Participating Fund to lend money directly to and, other than

closed-end

funds (including the Fund) and money market funds, borrow money directly from other Participating Funds for temporary purposes through the Interfund Program (each an Interfund Loan).

A Participating Fund may make unsecured borrowings under the Interfund Program if its outstanding borrowings from all sources, including those outside of the Interfund Program, immediately after such unsecured borrowing under the Interfund Program are equal to or less than 10% of its total assets, provided that if the borrowing Participating Fund has a secured loan outstanding from any other lender, including but not limited to another Participating Fund, the borrowing Participating Fund’s borrowing under the Interfund Program will be secured on at least an equal priority basis with at least an equivalent percentage of collateral to loan value as any outstanding loan that requires collateral. A Participating Fund may not borrow through the Interfund Program or from any other source if its total outstanding borrowings immediately after a borrowing would be more than 33 1/3% of its total assets or any lower threshold provided for by a Participating Fund’s fundamental or

non-fundamental

policy restriction.

No Participating Fund may lend to another Participating Fund through the Interfund Program if the loan would cause the lending Participating Fund’s aggregate outstanding loans under the Interfund Program to exceed 15% of its current net assets at the time of the loan. A Participating Fund’s Interfund Loans to any one Participating Fund may not exceed 5% of the lending Participating Fund’s net assets at the time of the loan. The duration of Interfund Loans will be limited to the time required to receive payment for securities sold, but in no event more than seven days. Interfund Loans effected within seven days of each other will be treated as separate loan transactions for purposes of this limitation. Each Interfund Loan may be called on one business day’s notice by a lending Participating Fund and may be repaid on any day by a borrowing Participating Fund.


34		Columbia Seligman Premium Technology Growth Fund, Inc. \| 2026

NOTES TO FINANCIAL STATEMENTS (continued)

June 30, 2026 (Unaudited)

Loans under the Interfund Program are subject to the risk that the borrowing Participating Fund could be unable to repay the loan when due, and a delay in repayment to the lending Participating Fund could result in a lost opportunity by the lending Participating Fund to invest those loaned assets and additional lending costs. Because the Investment Manager provides investment management services to both borrowing and lending Participating Funds, the Investment Manager may have a potential conflict of interest in determining that an Interfund Loan is comparable in credit quality to other high-quality money market instruments. The Participating Fund has adopted policies and procedures that are designed to manage potential conflicts of interest, but the administration of the Interfund Program may be subject to such conflicts.

As noted above, the Fund may only participate in the Interfund Program as a lending fund. The Fund did not lend money under the Interfund Program during the six months ended June 30, 2026.

Note 9. Investments in illiquid investments

The Fund may not acquire any illiquid investment if, immediately after the acquisition, the Fund would have invested more than 15% of Managed Assets in illiquid investments that are assets. For these purposes, an “illiquid investment” means any investment that the Fund reasonably expects cannot be sold or disposed of in current market conditions in seven calendar days or less without the sale or disposition significantly changing the market value of the investment.

Note 10. Risks and uncertainties

An investment in the Fund involves risks, including market risk and concentration risk, among others. The value of the Fund’s holdings and the Fund’s net asset value may go down. These declines may be due to factors affecting a particular issuer, or the result of, among other things, political, regulatory, market, economic or social developments affecting the relevant market(s) more generally.

Global economies and financial markets are increasingly interconnected, and conditions and events in one country, region or financial market may adversely impact issuers in a different country, region or financial market. These risks may be magnified if certain events or developments adversely interrupt the global supply chain; in these and other circumstances, such risks might affect companies worldwide. As a result, local, regional or global events such as terrorism, war, other conflicts, natural disasters, disease/virus outbreaks and epidemics or other public health issues, recessions, depressions or other events – or the potential for such events – could have a significant negative impact on global economic and market conditions.

To the extent that the Fund concentrates its investment in particular issuers, countries, geographic regions, industries or sectors, the Fund may be subject to greater risks of adverse developments in such areas of focus than a fund that invests in a wider variety of issuers, countries, geographic regions, industries, sectors or investments.

Note 11. Subsequent events

Management has evaluated the events and transactions that have occurred through the date the financial statements were issued and noted no items requiring adjustment of the financial statements or additional disclosure.

Note 12. Information regarding pending and settled legal proceedings

Ameriprise Financial and certain of its affiliates are involved in the normal course of business in legal proceedings which include regulatory inquiries, arbitration and litigation, including class actions concerning matters arising in connection with the conduct of their activities as part of a diversified financial services firm. Ameriprise Financial believes that the Fund is not currently the subject of, and that neither Ameriprise Financial nor any of its affiliates are the subject of, any pending legal, arbitration or regulatory proceedings that are likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund. Ameriprise Financial is required to make quarterly

(10-Q),

annual

(10-K)

and, as necessary,

8-K

filings with the Securities and Exchange Commission (SEC) on legal and regulatory matters that relate to Ameriprise Financial and its affiliates. Copies of these filings may be obtained by accessing the SEC website at www.sec.gov.

Although we believe proceedings are not likely to have a material adverse effect on the Fund or the ability of Ameriprise Financial or its affiliates to perform under their contracts with the Fund, these proceedings are subject to uncertainties

and, as such, it is inherently difficult to determine whether any loss is probable or even reasonably possible, or to reasonably estimate the amount of any loss that may result from such matters. An adverse outcome in one or more of these proceedings could result in adverse judgments, settlements, fines, penalties or other relief, and may lead to further claims, examinations, adverse publicity or reputational damage, each of which could have a material adverse effect on the consolidated financial condition or results of operations or financial condition of Ameriprise Financial or one or more of its affiliates that provide services to the Fund.

APPROVAL OF MANAGEMENT AGREEMENT

June 30, 2026 (Unaudited)

Columbia Management Investment Advisers, LLC (the Investment Manager, and together with its domestic and global affiliates, Columbia Threadneedle Investments), a wholly-owned subsidiary of Ameriprise Financial, Inc. (Ameriprise Financial), serves as the investment manager to Columbia Seligman Premium Technology Growth Fund, Inc. (the Fund). Under a management agreement (the Management Agreement), the Investment Manager provides investment advice and other services to the Fund. The Investment Manager also provides investment advice and other services to other funds in the Columbia Fund family (collectively, the Funds).

On an annual basis, the Fund’s Board of Trustees (the Board), including the independent Board members (the Independent Trustees), considers renewal of the Management Agreement. The Investment Manager prepared detailed reports for the Board and its Contracts Committee (including its Contracts Subcommittee) in March, April and June 2026, including reports providing the results of analyses performed by a third-party data provider, Broadridge Financial Solutions, Inc. (Broadridge), and comprehensive responses by the Investment Manager to written requests for information by independent legal counsel to the Independent Trustees (Independent Legal Counsel), to assist the Board in making this determination. In addition, throughout the year, the Board (or its committees or subcommittees) regularly meets with portfolio management teams and senior management personnel and reviews information prepared by the Investment Manager addressing the services the Investment Manager provides and Fund performance. The Board also accords appropriate weight to the work, deliberations and conclusions of the various committees (including their subcommittees), such as the Contracts Committee, the Investment Review Committee, the Audit Committee and the Compliance Committee, in determining whether to continue the Management Agreement.

The Board, at its June 18, 2026 Board meeting (the June Meeting), considered the renewal of the Management Agreement for an additional

one-year

term. At the June Meeting, Independent Legal Counsel reviewed with the Independent Trustees various factors relevant to the Board’s consideration of advisory agreements and the Board’s legal responsibilities related to such consideration. The Independent Trustees considered such information as they, their legal counsel or the Investment Manager believed reasonably necessary to evaluate and to approve the continuation of the Management Agreement. Among other things, the information and factors considered included the following:

•

Information on the investment performance of the Fund relative to the performance of a group of funds determined to be comparable to the Fund by Broadridge, as well as performance relative to one or more benchmarks;

•

Information on the Fund’s management fees and total expenses, including information comparing the Fund’s expenses to those of a group of comparable funds, as determined by Broadridge;

•

Terms of the Management Agreement;

•

Descriptions of various services performed by the Investment Manager under the Management Agreement, including portfolio management and portfolio trading practices;

•

Information regarding the resources of the Investment Manager, including information regarding senior management, portfolio managers and other personnel;

•

Information regarding the capabilities of the Investment Manager with respect to compliance monitoring services;

•

The profitability to the Investment Manager and its affiliates from their relationships with the Fund; and

•

Report provided by the Board’s independent fee consultant, JDL Consultants, LLC (JDL).

Following an analysis and discussion of the foregoing, and the factors identified below, the Board, including all of the Independent Trustees, approved the renewal of the Management Agreement.

Nature, extent and quality of services provided by the Investment Manager

The Board analyzed various reports and presentations it had received detailing the services performed by the Investment Manager, as well as its history, expertise, resources and relative capabilities, and the qualifications of its personnel.

APPROVAL OF MANAGEMENT AGREEMENT (continued)

June 30, 2026 (Unaudited)

The Board specifically considered the many developments during recent years concerning the services provided by the Investment Manager. Among other things, the Board noted the organization and depth of the equity and credit research departments. The Board further observed the enhancements to the investment risk management department’s processes, systems and oversight over the past several years. The Board also took into account the broad scope of services provided by the Investment Manager to the Fund, including, among other services, investment, risk and compliance oversight. The Board also took into account the information it received concerning the Investment Manager’s ability to attract and retain key portfolio management personnel and that it has sufficient resources to provide competitive and adequate compensation to investment personnel.

In connection with the Board’s evaluation of the overall package of services provided by the Investment Manager, the Board also considered the nature, quality and range of administrative services provided to the Fund by the Investment Manager, as well as the achievements in 2025 in the performance of administrative services, and noted the various enhancements anticipated for 2026. In evaluating the quality of services provided under the Management Agreement, the Board also took into account the organization and strength of the Fund’s and its service providers’ compliance programs. The Board also reviewed the financial condition of the Investment Manager and its affiliates and each entity’s ability to carry out its responsibilities under the Management Agreement.

In addition, the Board discussed the acceptability of the terms of the Management Agreement, noting that no changes were proposed from the form of agreement previously approved. The Board also noted the wide array of legal and compliance services provided to the Fund under the Management Agreement.

After reviewing these and related factors (including investment performance as discussed below), the Board concluded, within the context of their overall conclusions, that the nature, extent and quality of the services provided to the Fund under the Management Agreement supported the continuation of the Management Agreement.

Investment performance

The Board carefully reviewed the investment performance of the Fund, including detailed reports providing the results of analyses performed by each of the Investment Manager, Broadridge and JDL collectively showing, for various periods (including since manager inception): (i) the performance of the Fund (on a NAV and market basis), (ii) the Fund’s performance relative to peers and benchmarks and (iii) the net assets of the Fund. The Board observed that the Fund’s performance for certain periods ranked above median relative to its peers based on information provided by Broadridge.

The Board also reviewed a description of the third-party data provider’s methodology for identifying the Fund’s peer groups for purposes of performance and expense comparisons.

The Board also considered the Investment Manager’s performance and reputation generally. After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the performance of the Fund and the Investment Manager, in light of other considerations, supported the continuation of the Management Agreement.

Comparative fees, costs of services provided and the profits realized by the Investment Manager and its affiliates from their relationships with the Fund

The Board reviewed comparative fees and the costs of services provided under the Management Agreement. The Board members considered detailed comparative information set forth in an annual report on fees and expenses, including, among other things, data (based on analyses conducted by Broadridge and JDL) showing a comparison of the Fund’s expenses with median expenses paid by funds in its comparative peer universe, as well as data showing the Fund’s contribution to the Investment Manager’s profitability.

The Board considered the reports of JDL, which assisted in the Board’s analysis of the Funds’ performance and expenses and the reasonableness of the Funds’ fee rates. The Board accorded particular weight to the notion that a primary objective of the level of fees is to achieve a rational pricing model applied consistently across the various product lines in the Fund family, while assuring that the overall fees for each Fund (with certain exceptions) are generally in line with the current “pricing philosophy” such that Fund total expense ratios, in general, approximate or are lower than the median expense ratios of funds in the same Lipper comparison universe. With respect to the Fund, a

closed-end

Fund, the Board observed that although the Fund’s expense ratio was higher than the comparative

closed-end

fund peer group’s median expense ratio, the Fund is the only technology-focused fund in the universe. The Board further observed that, unlike many technology-focused

open-end

funds, the Fund employs a unique options-writing strategy designed to cushion its downside performance.

APPROVAL OF MANAGEMENT AGREEMENT (continued)

June 30, 2026 (Unaudited)

After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the levels of management fees and expenses of the Fund, in light of other considerations, supported the continuation of the Management Agreement.

The Board also considered the profitability of the Investment Manager and its affiliates in connection with the Investment Manager providing management services to the Fund. With respect to the profitability of the Investment Manager and its affiliates, the Independent Trustees referred to information discussing the profitability to the Investment Manager and Ameriprise Financial from managing the Funds. The Board considered that the profitability generated by the Investment Manager in 2025 had increased slightly from 2024 levels due to a variety of factors, including the increased assets under management of the Funds. It also took into account the indirect economic benefits flowing to the Investment Manager or its affiliates in connection with managing the Funds, such as the enhanced ability to offer various other financial products to Ameriprise Financial customers, soft dollar benefits and overall reputational advantages. The Board noted that the fees paid by the Fund should permit the Investment Manager to offer competitive compensation to its personnel, make necessary investments in its business and earn an appropriate profit. After reviewing these and related factors, the Board concluded, within the context of their overall conclusions, that the costs of services provided and the profitability to the Investment Manager and its affiliates from their relationships with the Fund supported the continuation of the Management Agreement.

Economies of scale

The Board considered the economies of scale that might be realized as the Fund’s net asset level grows and took note of the extent to which Fund shareholders might also benefit from such growth. In this regard, the Board took into account that management fees decline as Fund assets exceed various breakpoints, all of which have not been surpassed. The Board observed that the Management Agreement thus provides for breakpoints in the management fee rate schedule that allow opportunities for shareholders to realize lower fees as Fund assets grow and that there are additional opportunities through other means for sharing economies of scale with shareholders. The Board observed, however, that there is limited potential for economies of scale that would inure to the benefit of shareholders, given the

closed-end

nature of the Fund.

Conclusion

The Board reviewed all of the above considerations in reaching its decision to approve the continuation of the Management Agreement. In reaching its conclusions, no single factor was determinative.

On June 18, 2026, the Board, including all of the Independent Trustees, determined that fees payable under the Management Agreement were fair and reasonable in light of the extent and quality of services provided and approved the renewal of the Management Agreement.
