Thrivent All Cap Portfolio

------

Investment Objective

The investment objective of Thrivent All Cap Portfolio (the "Portfolio") is to seek long-term growth of capital.

Fees and Expenses

The table below describes the fees and expenses that you may pay if you buy, hold and/or sell shares of the Portfolio. If you own a variable annuity contract or variable life insurance contract, you will have additional fees and expenses. Please refer to the prospectus for your variable contract for additional information about fees and expenses associated with your contract.

**Shareholder Fees** 

(fees paid directly from your investment)

---

| |
|:---|
| &nbsp;&nbsp; Maximum Sales Charge (load) Imposed On <br> Purchases (as a % of offering price)<br>|
| &nbsp;&nbsp; Maximum Deferred Sales Charge (load) (as a % of <br> the net asset value)<br>|

---

**Annual Portfolio Operating Expenses**

(expenses that you pay each year as a percentage of the value of your investment)

---

| | |
|:---|:---|
| Management Fees | 0.55% |
| Other Expenses | 0.11% |
| Total Annual Portfolio Operating Expenses | 0.66% |

---

**Example**

The example below is intended to help you compare the cost of investing in the Portfolio with the cost of investing in other mutual funds. The Portfolio is an investment option for variable contracts, and the example does not include charges imposed by variable contracts. If variable contract charges were included, your expenses would be higher than those shown. The example assumes that you invest $10,000 in the Portfolio for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year, and that the Portfolio's operating expenses remain the same. Although your actual cost may be higher or lower, based on the foregoing assumptions, your cost would be:

---

| | | | |
|:---|:---|:---|:---|
| **1 Year** | **3 Years** | **5 Years** | **10 Years** |
| $67 | $211 | $368 | $822 |

---

**Portfolio Turnover**

The Portfolio pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Portfolio shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the Portfolio's performance. During the most recent fiscal year, the Portfolio's portfolio turnover rate was 131% of the average value of its portfolio.

Principal Strategies

The Portfolio seeks to achieve its objective by investing primarily in common stocks of companies of any market capitalization or investment style. In buying and selling securities for the Portfolio, the Adviser uses an active strategy. This strategy consists of a disciplined approach that involves computer-aided, quantitative analysis of fundamental, technical and risk-related factors. The Adviser's factor model (a method of analyzing and combining multiple data sources) systematically reviews thousands of stocks, using data such as historical earnings growth and expected future growth, valuation, price momentum, and other quantitative factors to forecast return potential. Then, risk characteristics of potential investments and covariation among securities are analyzed along with the return forecasts in determining the Portfolio's holdings.

Principal Risks

The Portfolio is subject to the following principal investment risks, which you should review carefully and in entirety. An investment in the Portfolio is not a deposit or other obligation of Thrivent Trust Company, Thrivent Bank, or any bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other federal agency. The Portfolio may not achieve its investment objective and you could lose money by investing in the Portfolio.

**Equity Security Risk.** Equity securities held by the Portfolio may decline significantly in price, sometimes rapidly or unpredictably, over short or extended periods of time, and such declines may occur because of declines in the equity market as a whole, or because of declines in only a particular country, geographic region, company, industry, or sector of the market. From time to time, the Portfolio may invest a significant portion of its assets in companies in one particular country or geographic region or one or more related sectors or industries, which would make the Portfolio more vulnerable to adverse developments affecting such countries, geographic regions, sectors or industries. Equity securities generally do not move in the same direction at the same time and are generally more volatile than most debt securities.

**Market Risk.** Over time, securities markets generally tend to move in cycles with periods when security prices rise and periods when security prices decline. The value of the Portfolio's investments may move with these cycles and, in some instances, increase or decrease more than the applicable market(s) as measured by the Portfolio's benchmark index(es). The securities markets may also decline because of factors that affect a particular industry or market sector, or due to impacts from domestic or global events, including regulatory events, economic downturn, government shutdowns, the spread of infectious illness such as the outbreak of COVID-19, public health crises, war, terrorism, social unrest, recessions, natural disasters or similar events.

**Large Cap Risk.** Large-sized companies may be unable to respond quickly to new competitive challenges such as changes in technology. They may also not be able to attain the high growth rate of successful smaller companies, especially during extended periods of economic expansion.

**Investment Adviser Risk.** The Portfolio is actively managed and the success of its investment strategy depends significantly on

------

the skills of the Adviser in assessing the potential of the investments in which the Portfolio invests. The assessment of potential Portfolio investments may prove incorrect, resulting in losses or poor performance, even in rising markets. Poor investments by the Adviser may cause a Portfolio to underperform relative to its benchmark or similar funds. There is also no guarantee that the Adviser will be able to effectively implement the Portfolio's investment objective.

**Issuer Risk.** Issuer risk is the possibility that factors specific to an issuer to which the Portfolio is exposed will affect the market prices of the issuer's securities and therefore the value of the Portfolio.

**Mid Cap Risk.** Medium-sized companies often have greater price volatility, lower trading volume, and less liquidity than larger, more-established companies. These companies tend to have smaller revenues, narrower product lines, less management depth and experience, smaller shares of their product or service markets, fewer financial resources, and less competitive strength than larger companies.

**Portfolio Turnover Rate Risk.** The Portfolio may engage in active and frequent trading of portfolio securities in implementing its principal investment strategies. A high rate of portfolio turnover (100% or more) involves correspondingly greater expenses which are borne by the Portfolio and its shareholders and may also result in short-term capital gains taxable to shareholders.

**Quantitative Investing Risk.** Securities selected according to a quantitative analysis methodology can perform differently from the market as a whole based on the model and the factors used in the analysis, the weight placed on each factor and changes in the factor's historical trends. Such models are based on assumptions relating to these and other market factors, and the models may not take into account certain factors, or perform as intended, and may result in a decline in the value of the Portfolio's portfolio. Among other risks, results generated by such models may be impaired by errors in human judgment, data imprecision, software or other technology systems malfunctions, or programming flaws. Such models may not perform as expected or may underperform in periods of market volatility.

**Sector Risk.** Companies with similar characteristics may be grouped together in broad categories called sectors. From time to time, the Portfolio may have significant positions in one or more sectors of the market. To the extent the Portfolio invests more heavily in particular sectors than others, its performance may be more susceptible to developments that significantly affect those sectors. Individual sectors may be more volatile, and may perform differently, than the broader market. The industries that constitute a sector may all react in the same way to economic, political or regulatory events.

**Small Cap Risk.** Smaller, less seasoned companies often have greater price volatility, lower trading volume, and less liquidity than larger, more established companies. These companies tend to have small revenues, narrower product lines, less management depth and experience, small shares of their product or service markets, fewer financial resources, and less competitive strength than larger companies. Such companies seldom pay significant dividends that could soften the impact of a falling market on returns.

Performance

The following bar chart and table beneath it provide some indication of the risks of investing in the Portfolio. The bar chart and table include the effects of Portfolio expenses, but not

charges or deductions against your variable contract. They also assume that you sold your investment at the end of the period. The bar chart shows the Portfolio's performance from year to year while the table shows how the Portfolio's average annual returns for the indicated periods compare with those of an appropriate broad-based securities market index and a more narrowly based index. Because shares of the Portfolio are offered through variable life insurance and variable annuity contracts, you should carefully review the variable contract prospectus for information on applicable charges and expenses. If the charges and deductions against your variable contract were included, returns would be lower than those shown.

The Portfolio's past performance is not necessarily an indication of how it will perform in the future. Updated performance information is available on the Portfolio's website at thrivent.com or by calling 800-847-4836.

The Portfolio compares its performance to the Russell 3000<sup>®</sup> Index, an appropriate broad-based securities market index that represents the overall domestic equity market in which the Portfolio may invest. The Portfolio also compares its performance to the S&P Composite 1500<sup>®</sup> Index, which more closely reflects the market segments in which the Portfolio invests. The index descriptions appear in the "Index Descriptions" section of the prospectus.

Payments to Broker-Dealers and Other Financial Intermediaries

If you purchase your variable contract through a broker-dealer or other financial intermediary, Thrivent, the other issuing insurance company or their related companies may pay the intermediary for the sale of the contract, the selection of the Portfolio and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your financial professional to recommend the Portfolio over another investment. Ask your financial professional or visit your financial intermediary's website for more information.
