 **INVESTMENT OBJECTIVE**<br>

**Janus Henderson Small Cap Growth Alpha ETF** seeks investment results that correspond generally, before fees and expenses, to the performance of its underlying index, the Janus Henderson Small Cap Growth Alpha Index (the "Underlying Index").

 **FEES AND EXPENSES OF THE FUND**<br>

This table describes the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. Investors may pay brokerage commissions and other fees to financial intermediaries on their purchases and sales of Fund shares, which are not reflected in the table or in the example below.

---

| | |
|:---|:---|
| **ANNUAL FUND OPERATING EXPENSES** <br> (expenses that you pay each year as a percentage of the value of your investment) | |
|  Management Fees | 0.30% |
|  Other Expenses | 0.00% |
|  Total Annual Fund Operating Expenses | 0.30% |

---

**EXAMPLE:** 

The Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then sell 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 Fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

---

| | | | |
|:---|:---|:---|:---|
| **1 Year** | **3 Years** | **5 Years** | **10 Years** |
| $&nbsp;&nbsp;&nbsp;&nbsp;31 | $&nbsp;&nbsp;&nbsp;&nbsp;97 | $&nbsp;&nbsp;&nbsp;&nbsp;169 | $&nbsp;&nbsp;&nbsp;&nbsp;381 |

---

**Portfolio Turnover:** The Fund 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 Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 107% of the average value of its portfolio.

 **PRINCIPAL INVESTMENT STRATEGIES**<br>

The Fund pursues its investment objective by normally investing at least 80% of its net assets (plus any borrowings for investment purposes) in the securities that comprise the Janus Henderson Small Cap Growth Alpha Index ("Underlying Index").

The Underlying Index is composed of common stocks of small-sized companies that are included in the Solactive Small Cap Index, a universe of 2,000 small-sized capitalization stocks. The Solactive Small Cap Index uses the total public market value, or "free-float," capitalization of a stock to determine whether to include such stock in the Solactive Small Cap Index. The Underlying Index is designed to select small-sized capitalization stocks that are poised for "smart growth" by evaluating each company's performance in three critical areas: growth, profitability, and capital efficiency. Using a proprietary quantitative methodology, such stocks are scored based on fundamental measures of their growth, profitability, and capital efficiency, and the top 10% of such eligible stocks scoring the highest become the constituents of the Underlying Index. To arrive at the top 10%, for each security in the stated universe, the quantitative methodology assigns a score in each of 10 different fundamental factors, relative to other eligible securities. The fundamental factors include measures that the Adviser believes are tied to a stock's outperformance relative to other small cap stocks,

1<sub>½</sub>Janus Henderson Small Cap Growth Alpha ETF

------

and indicate a company's performance with respect to growth (such as the revenue growth rate over 2- 5- and 8- year periods), profitability (such as margin expansion, profit margin and earnings per share over time) and capital efficiency (such as returns on invested capital). The scores for each stock within a factor are then added together across the 10 factors, with equal weighting, to arrive at an overall score for each stock. The stocks with the highest 10% of scores are then weighted within the Underlying Index according to their market capitalization. Finally, the stocks are sector-weighted to reflect the sector allocation weight of Janus Henderson Venture Fund, based on its most recent publicly available holdings. A stock may not represent more than 3% of the Underlying Index. The Underlying Index seeks risk adjusted outperformance relative to a market capitalization weighted universe of small-sized capitalization growth stocks. Market capitalizations within the Underlying Index will vary, but as of October 31, 2022, they ranged from approximately $5 million to $6.5 billion. The Underlying Index is rebalanced on a quarterly basis based on the methodology described above.

The Fund uses a "passive," index-based approach in seeking performance that corresponds to the performance of the Underlying Index. The Fund generally will use a replication methodology, meaning it will invest in the securities composing the Underlying Index in proportion to the weightings in the Underlying Index. However, the Fund may utilize a sampling methodology under various circumstances in which it may not be possible or practicable to purchase all of the securities in the Underlying Index.

The Adviser expects that over time, if the Fund has sufficient assets, the correlation between the Fund's performance, before fees and expenses, and that of the Underlying Index will be 95% or better. A figure of 100% would indicate perfect correlation.

The Fund may also invest in investments that are not included in the Underlying Index, but which the Adviser believes will help the Fund track the Underlying Index. Such investments include stocks, shares of other investment companies, cash and cash equivalents, including affiliated or non-affiliated money market funds (or unregistered cash management pooled investment vehicles that operate as money market funds).

To the extent the Underlying Index concentrates (i.e., holds 25% or more of its total assets) in the securities of a particular industry or group of industries, the Fund will concentrate its investments to approximately the same extent as the Underlying Index. As of October 31, 2022, the Underlying Index did not concentrate in a particular industry or group of industries. For more recent information, see the Fund's daily portfolio holdings posted on the ETF portion of the Janus Henderson website.

The Fund may seek to earn additional income through lending its securities to certain qualified broker-dealers and institutions on a short-term or long-term basis, in an amount equal to up to one-third of its total assets as determined at the time of the loan origination.

The Underlying Index is compiled and administered by Janus Henderson Indices LLC ("JH Indices" or the "Index Provider"). JH Indices is affiliated with the Fund and the Adviser.

 **PRINCIPAL INVESTMENT RISKS**<br>

The biggest risk is that the Fund's returns will vary, and you could lose money. The Fund is designed for long-term investors interested in an index-based portfolio of equity investments, including common stocks. Common stocks tend to be more volatile than many other investment choices. The principal risks associated with investing in the Fund are set forth below.

***Market Risk.*** The value of the Fund's portfolio may decrease due to short-term market movements and over more prolonged market downturns. As a result, the Fund's net asset value ("NAV") may decrease. Market risk may affect a single issuer, industry, economic sector, or the market as a whole. The Underlying Index focuses on the small-sized capitalization sector of the stock market, and therefore at times the Fund may underperform the overall stock market. Market risk may be magnified if certain social, political, economic and other conditions and events (such as terrorism, conflicts, including related sanctions, social unrest, natural disasters, epidemics and pandemics, including COVID-19) adversely interrupt the global economy and financial markets. It is important to understand that the value of your investment may fall, sometimes sharply, in response to changes in the market, and you could lose money.

***Equity Investing Risk.*** The Fund's investment in the securities composing the Underlying Index involves risks of investing in a portfolio of equity securities, such as market fluctuations, changes in interest rates and perceived trends in stock prices.

***Small-Sized Companies Risk.*** The Fund's investments in securities issued by small-sized companies, which can include smaller, start-up companies offering emerging products or services, may involve greater risks than are customarily associated with larger, more established companies. Securities issued by small-sized companies tend to be more volatile and somewhat more speculative than securities issued by larger or more established companies and may underperform as compared to the securities

2<sub>½</sub>Janus Henderson Small Cap Growth Alpha ETF

------

of larger or more established companies. Securities issued by micro-capitalization companies tend to be significantly more volatile, and more vulnerable to adverse business and economic developments, than those of larger companies. For example, small- and micro-capitalization companies may be more likely to merge with or be acquired by another company, resulting in de-listing of the securities held by the Fund.

***Growth Securities Risk.*** Securities of companies perceived to be "growth" companies may be more volatile than other stocks and may involve special risks. If the perception of a company's growth potential, based on the quantitative methodology applied in constructing the Underlying Index, is not realized, the securities purchased may not perform as expected, reducing the Fund's returns. In addition, because different types of stocks tend to shift in and out of favor depending on market and economic conditions, "growth" stocks may perform differently from the market as a whole and other types of securities. 

***Investment Style Risk.*** Returns from small-sized capitalization stocks may trail returns from the overall stock market. Small-cap stocks may go through cycles of doing better or worse than other segments of the stock market or the stock market in general. These cycles may continue for extended periods of time.

***Concentration Risk.*** The Fund's assets will generally be concentrated in an industry or group of industries to the extent that the Fund's Underlying Index concentrates in a particular industry or group of industries. To the extent the Fund invests a substantial portion of its assets in an industry or group of industries, market or economic factors impacting that industry or group of industries could have a significant effect on the value of the Fund's investments. Companies in the same or similar industries may share common characteristics and are more likely to react similarly to industry-specific market or economic developments. The Fund's performance may be more volatile when the Fund's investments are less diversified across industries. The Fund's assets will not be concentrated if the Underlying Index does not concentrate in a particular industry or group of industries.

***Early Close/Trading Halt Risk.*** An exchange or market may close or issue trading halts on specific securities, or the ability to buy or sell certain securities or financial instruments may be restricted, which may result in the Fund being unable to buy or sell certain securities or financial instruments. In such circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses.

***Index Tracking Risk.*** The Fund's return may not match or achieve a high degree of correlation with the return of the Underlying Index. To the extent the Fund utilizes a sampling approach, it may experience tracking error to a greater extent than if the Fund sought to replicate the Underlying Index. In addition, the Fund may hold fewer than the total number of securities in the Underlying Index. Further, the Fund may hold securities or other investments not included in the Underlying Index but which the Adviser believes will help the Fund track the Underlying Index. Such investments may not perform as expected.

***Index Provider Risk.*** The Fund seeks to achieve returns that generally correspond, before fees and expenses, to the performance of the Underlying Index, as published by the Index Provider. There is no assurance that the Index Provider will compile the Underlying Index accurately, or that the Underlying Index will be determined, composed or calculated accurately. While the Index Provider gives descriptions of what the Underlying Index is designed to achieve, the Index Provider generally does not provide any warranty or accept any liability in relation to the quality, accuracy or completeness of data in such index, and it generally does not guarantee that the Underlying Index will be in line with its methodology. The Index Provider may unilaterally take certain actions that materially change the operation or expected composition of the Underlying Index (including altering the frequency of index rebalances). Additionally, errors made by the Index Provider with respect to the quality, accuracy and completeness of the data within the Underlying Index may occur from time to time and may not be identified and corrected by the Index Provider for a period of time, if at all. Therefore, gains, losses or costs associated with Index Provider errors or operational discretion will generally be borne by the Fund and its shareholders.

***Methodology and Model Risk.*** Neither the Fund nor the Adviser can offer assurances that tracking the Underlying Index will maximize returns or minimize risk, or be appropriate for every investor seeking a particular risk profile. Underlying Index risks include, but are not limited to, the risk that the factors used to determine the components of the Underlying Index, as applied by the Index Provider in accordance with the Underlying Index methodology, might not select securities that individually, or in the aggregate, outperform the broader small-sized capitalization universe. In addition, the Underlying Index was designed based on historically relevant fundamental factors and may not provide risk-adjusted outperformance in the future.

***Passive Investment Risk.*** The Fund is not actively managed and therefore the Fund might not sell shares of a security due to current or projected underperformance of a security, industry or sector, unless that security is removed from the Underlying Index or the selling of shares is otherwise required upon a rebalancing of the Underlying Index.

***Portfolio Turnover Risk***. Increased portfolio turnover may result in higher costs which may have a negative effect on the Fund's performance. In addition, higher portfolio turnover may result in the acceleration of capital gains and the recognition of greater levels of short-term capital gains, which are taxed at ordinary federal income tax rates when distributed to shareholders.

***Securities Lending Risk.*** Securities lending involves a risk of loss because the borrower may fail to return the securities in a timely manner or at all. If the Fund lends its securities and is unable to recover the securities loaned, it may sell the collateral and purchase a replacement security in the market. Lending securities entails a risk of loss to the Fund if and to the extent that the market value of the loaned securities increases and the collateral is not increased accordingly. Any cash received as collateral for loaned securities will be invested in an affiliated cash management vehicle or time deposits. This investment is subject to market appreciation or depreciation and the Fund will bear any loss on the investment of its cash collateral.

***Exchange Listing and Trading Issues Risk.*** Although Fund shares are listed for trading on the NASDAQ (the "Exchange"), there can be no assurance that an active trading market for such shares will develop or be maintained. The lack of an active market for Fund shares, as well as periods of high volatility, disruptions in the creation/redemption process, or factors affecting the liquidity of the underlying securities held by the Fund, may result in the Fund's shares trading at a premium or discount to its NAV.

Trading in Fund shares may be halted due to market conditions or for reasons that, in the view of the Exchange, make trading in Fund shares inadvisable. In addition, trading is subject to trading halts caused by extraordinary market volatility pursuant to the Exchange's "circuit breaker" rules. There can be no assurance that the requirements of the Exchange necessary to maintain the Fund's listing will continue to be met or will remain unchanged.

***Fluctuation of NAV and Market Price Risk.*** The NAV of the Fund's shares will generally fluctuate with changes in the market value of the Fund's securities holdings. The market prices of the Fund's shares will generally fluctuate in accordance with changes in the Fund's NAV and supply and demand of shares on the Exchange. Volatile market conditions, an absence of trading in shares of the Fund, or a high volume of trading in the Fund, may result in trading prices in the Fund's shares that differ significantly from the Fund's NAV. Additionally, during a "flash crash," the market prices of the Fund's shares may decline suddenly and significantly, resulting in Fund shares trading at a substantial discount to NAV. Such a decline may not reflect the performance of the portfolio securities held by the Fund. Flash crashes may cause Authorized Participants and other market makers to limit or cease trading in the Fund's shares for temporary or longer periods, which may result in an increase in the variance between market prices of the Fund's shares and the Fund's NAV. Shareholders could suffer significant losses to the extent that they sell shares at these temporarily low market prices.

It cannot be predicted whether Fund shares will trade below, at or above the Fund's NAV. Further, the securities held by the Fund may be traded in markets that close at a different time than the Exchange. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the Exchange is open but after the applicable market closing or fixing settlement times, bid-ask spreads and the resulting premium or discount to the Fund shares' NAV is likely to widen. Similarly, the Exchange may be closed at times or days when markets for securities held by the Fund are open, which may increase bid-ask spreads and the resulting premium or discount to the Fund shares' NAV when the Exchange re-opens. The Fund's bid-ask spread and the resulting premium or discount to the Fund's NAV may also be impacted by the liquidity of the underlying securities held by the Fund, particularly in instances of significant volatility of the underlying securities.

***Authorized Participant Risk.*** The Fund may have a limited number of financial institutions that may act as Authorized Participants ("APs"). Only APs who have entered into agreements with the Fund's distributor may engage in creation or redemption transactions directly with the Fund. These APs have no obligation to submit creation or redemption orders and, as a result, there is no assurance that an active trading market for the Fund's shares will be established or maintained. This risk may be heightened to the extent that the securities underlying the Fund are traded outside of a collateralized settlement system. In that case, APs may be required to post collateral on certain trades on an agency basis (i.e., on behalf of other market participants), which only a limited number of APs may be willing or able to do. Additionally, to the extent that those APs exit the business or are unable to process creation and/or redemption orders, and no other AP is able to step forward to create and redeem in either of these cases, shares may trade like closed-end fund shares at a premium or a discount to NAV and possibly face delisting.

*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.*

 **MANAGEMENT**<br>

**Investment Adviser:** Janus Henderson Investors US LLC

**Scott M. Weiner**, DPhil, is Co-Portfolio Manager of the Fund, which he has co-managed since inception.

 **PURCHASE AND SALE OF FUND SHARES**<br>

Unlike shares of traditional mutual funds, shares of the Fund are not individually redeemable and may only be purchased or redeemed directly from the Fund at NAV in large increments called "Creation Units" through APs. The Adviser may modify the Creation Unit size with prior notification to the Fund's APs. See the ETF portion of the Janus Henderson website for the Fund's current Creation Unit size. Creation Unit transactions are conducted in exchange for the deposit or delivery of a designated portfolio of in-kind securities with a cash balancing amount and/or all cash. Except when aggregated in Creation Units, Fund shares are not redeemable securities of the Fund. Shares of the Fund are listed and trade on the Exchange, and individual investors can purchase or sell shares in much smaller increments for cash in the secondary market through a broker-dealer. These transactions, which do not involve the Fund, are made at market prices that may vary throughout the day and differ from the Fund's NAV. As a result, you may pay more than NAV (at a premium) when you purchase shares, and receive less than NAV (at a discount) when you sell shares, in the secondary market.

Investors purchasing or selling shares in the secondary market may also incur additional costs, including brokerage commissions and an investor may incur costs attributable to the difference between the highest price a buyer is willing to pay to purchase shares of the Fund (bid) and the lowest price a seller is willing to accept for shares of the Fund (ask) when buying or selling shares in the secondary market (the "bid-ask spread"). Historical information regarding the Fund's bid/ask spread can be accessed on the Fund's website at janushenderson.com/performance by selecting the Fund.

 **TAX INFORMATION**<br>

The Fund's distributions are generally taxable, and will be taxed as ordinary income or capital gains, unless you are investing through a tax-advantaged arrangement, such as a 401(k) plan or an individual retirement account (in which case you may be taxed at ordinary income tax rates upon withdrawal of your investment from such account). A sale of Fund shares may result in a capital gain or loss.

 **PAYMENTS TO BROKER-DEALERS AND OTHER FINANCIAL INTERMEDIARIES**<br>

If you purchase the Fund through a broker-dealer or other financial intermediary (such as a bank), the Adviser and/or its affiliates may pay broker-dealers or intermediaries for the sale and/or maintenance of Fund shares and related services. These payments may create a conflict of interest by influencing the broker-dealer or other intermediary and your salesperson to recommend the Fund over another investment. Ask your salesperson or visit your financial intermediary's website for more information.
