Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? American Century Diversified Corporate Bond ETF returned 10.26% for the reporting period ended August 31, 2024. The fund seeks to provide current income. The commentary below refers to the fund’s performance compared to the Bloomberg U.S. Intermediate Corporate Bond Index. • Treasury yields declined and inflation moderated for the 12-month period, which supported widespread gains across the U.S. fixed-income market. Corporate bonds generally outperformed the broad market, as economic growth and corporate earnings remained resilient and credit spreads tightened. • Security selection was a primary driver of fund performance. The financial institutions sector was a top contributor, largely due to our selections among banks, real estate investment trusts and finance companies. Holdings among retailers and technology companies also boosted results. Our selections in the consumer noncyclical sector modestly detracted, mostly due to the food and beverage industry. • Our longer-than-index duration position also aided fund performance. This strategy proved helpful as yields declined for the period. • Sector allocation also broadly contributed to performance. An out-of-index position in high-yield corporate bonds, which outperformed investment-grade corporates for the period, was the main contributor. Additionally, an out-of-index stake in government bonds and an underweight position in the technology sector also boosted results.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? American Century Diversified Municipal Bond ETF returned 6.75% for the reporting period ended August 31, 2024. The fund seeks current income that is exempt from federal income tax. The commentary below refers to the fund’s performance compared to the S&P National AMT-Free Municipal Bond Index. • Municipal bonds (munis) delivered solid gains for the 12-month period. Falling Treasury yields, moderating inflation and generally healthy demand for munis provided a positive backdrop for the asset class. • Sector allocation was a key contributor to performance, largely due to out-of-index exposure to corporate munis, retirement communities and hospital bonds. Additionally, an out-of-index stake in high-yield munis, which outperformed investment-grade munis for the period, boosted fund performance. • Our longer-than-index duration position also aided fund performance. This strategy proved helpful as yields declined for the period. • In addition, our security selection efforts lifted fund performance. Selections in the local general obligation (GO), special tax and public university sectors were top contributors. These holdings more than offset slightly negative selection effects in the public power, state GO and private university sectors.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? American Century Emerging Markets Bond ETF returned 12.83% for the reporting period ended August 31, 2024. The fund seeks to provide current income and capital appreciation. The commentary below refers to the fund’s performance compared to the JPMorgan EMBI Global Diversified Index. • Emerging markets (EM) bonds rallied for the 12-month period amid falling global interest rates, resilient U.S. economic growth and improving growth prospects in several EM countries. Additionally, growing expectations for the Federal Reserve to cut interest rates supported gains among EM bonds. • Our sector allocation decisions detracted from fund performance, particularly out-of-index positions in corporate securities. An underweight position versus the index in sovereign securities, particularly distressed sovereigns, also weighed on results. A position in high-yield credit default swaps, which we used to hedge the fund’s high-yield exposure, detracted from performance as high-yield securities outperformed. • Meanwhile, our security selection efforts aided performance, led by sovereign securities in the Middle East, the Asia/Pacific region and Europe. Our choices in these regions more than offset negative selection effects from sovereigns in Africa and Latin America. Our selections among quasi-sovereigns in the Asia/Pacific region and in Latin America lifted results. • The fund’s duration, which remained longer than the index’s, modestly contributed to performance in the declining rate environment.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? American Century Focused Dynamic Growth ETF returned 32.14% for the reporting period ended August 31, 2024. The fund seeks long-term capital growth. The commentary below refers to the fund’s performance compared to the Russell 1000 Growth Index. • A risk-on environment over much of the 12-month period broadly favored large-cap stocks, particularly those related to artificial intelligence. This was despite elevated interest rates and worries about a recession that did not happen. Concerns about AI investment and slowing economic conditions led to a rotation to lower volatility and higher-quality stocks near the end of the period. • Some of the leading contributions to performance came from communication services stocks. Amid economic uncertainty, investors sought strong growth and dependable free cash flows. This explains the outperformance of Meta Platforms and Netflix. Among individual contributors, an overweight position in NVIDIA benefited from the build-out in AI. • Stock choices among health care stocks were another source of strength. The sector broadly benefited from solid earnings growth and attractive valuations. Our overweight holdings in robotic surgical device maker Intuitive Surgical and biotechnology company Regeneron Pharmaceuticals also drove strong results and stock performance through innovation and new product cycles. • Selection and allocation decisions meant the consumer staples sector detracted most from performance. Beverage companies Constellation Brands and The Boston Beer Co. lagged, citing macroeconomic headwinds to their business. The leading individual detractor was electric vehicle maker Tesla, which also suffered from weakening economic conditions and high interest rates.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? American Century Focused Large Cap Value ETF returned 20.29% for the reporting period ended August 31, 2024. The fund seeks long-term capital growth. The commentary below refers to the fund’s performance compared to the Russell 1000 Value Index. • A risk-on environment over much of the period broadly favored large-cap stocks, particularly those related to artificial intelligence. This occurred despite elevated interest rates and worries about a recession that did not happen. Concerns about AI investment and slowing economic conditions led to a rotation toward lower volatility and higher-quality stocks near the end of the period. • Allocation in the health care sector weighed on performance. The fund is overweight health care, particularly in industries like health care equipment and supplies that have been beset by investors’ concerns about new weight-loss drugs. These treatments have been a drag on some medical device companies’ share prices. We believe this is a transitory issue and utilization should normalize. • Choices of investments in the industrials sector also curbed performance. While the fund is broadly underweight in the sector, an overweight holding in the air freight and logistics industry—specifically, United Parcel Service—detracted from relative results. Underweight positions in the electrical equipment and machinery industries also slowed performance. • Allocation among names in the energy sector contributed to the fund’s performance. Falling oil prices generally pressured stocks in the oil, gas and consumable fuels industry, so the fund’s underweight position and allocation among names in the industry helped results. Not owning names in the energy equipment and services industry also aided relative performance.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? American Century Low Volatility ETF returned 20.05% for the reporting period ended August 31, 2024. The fund seeks capital appreciation. The commentary below refers to the fund’s performance compared to the S&P 500 Index. • Lower-volatility equities have historically done well relative to the broader market when stocks fall, but lag when they rally. Stocks performed very well during the fiscal year, repeatedly reaching record highs, led by the so-called Magnificent Seven mega-cap technology stocks. Consistent with managing the risk of unprecedented market concentration, we underweighted these seven names. • The relative lack of exposure to the Magnificent Seven can be seen in the list of the portfolio’s leading detractors from performance compared with the benchmark. The number-one relative detractor was NVIDIA, to which the portfolio had no exposure. Other notable relative detractors were underweight positions in Meta Platforms (parent of Facebook) and Microsoft. • Some of the key contributions to relative results came from industrials and materials stocks, which benefited from fading recession fears and hopes for an economic soft landing. Returning to the Magnificent Seven, having no exposure to electric vehicle maker Tesla significantly benefited relative results. The stock performed very well in 2023 but gave back some of those gains in 2024.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? American Century Mid Cap Growth Impact ETF returned 26.29% for the reporting period ended August 31, 2024. This fund seeks long-term capital growth. The commentary below refers to the fund’s performance compared to the Russell Midcap Growth Index. • A risk-on environment over much of the 12-month period broadly favored large-cap stocks, particularly those related to artificial intelligence. This was despite elevated interest rates and worries about a recession that did not happen. Concerns about AI investment and slowing economic conditions led to a rotation to lower volatility and higher-quality stocks near the end of the period. • Stock picks in the industrials sector contributed to the fund’s performance during the 12-month period. Investment in Vertiv Holdings helped drive outperformance as the company, which provides electrical cooling infrastructure equipment, benefited from enthusiasm for AI. Strategic selections in the building products industry also gave results a lift. • Choices of investments in the health care sector contributed to performance. In particular, the biotechnology industry, led by an overweight position in Viking Therapeutics, helped relative results. Shares in Viking advanced on encouraging data for its weight-loss drug. In addition, avoiding certain names in the health care technology and pharmaceuticals industries proved fortuitous. • Security selection in the financials sector slowed results. The fund is broadly underweight in the sector and allocation among names in the financial services and banking industries curbed performance.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? American Century Multisector Floating Income ETF returned 6.99% for the reporting period ended August 31, 2024. The fund seeks income. As a secondary objective, the fund seeks long-term capital appreciation. The commentary below refers to the fund’s performance compared to the Bloomberg U.S. 1-3 Month Treasury Bill Index. • Treasury yields declined and inflation moderated for the 12-month period, which supported widespread gains across the U.S. fixed-income market. Credit-sensitive securities generally outperformed government securities for the period. Against this backdrop, our out-of-index allocation to the securitized sector aided performance. • Our collateralized loan obligations, non-agency commercial mortgage-backed securities and non-agency collateralized mortgage obligations (CMOs) were top contributors. Exposure to asset-backed securities and agency CMOs also aided performance, but to a smaller degree. • An underweight position versus the index in government securities modestly detracted from performance.

The commentary below refers to the fund’s performance compared to the Bloomberg U.S. Aggregate Bond Index. • Treasury yields declined and inflation moderated for the 12-month period, which supported widespread gains across the U.S. fixed-income market. Credit-sensitive securities generally outperformed government securities for the period. Against this backdrop, our sector allocations broadly aided performance. • An overweight position versus the index in investment-grade credit, which outperformed the broader U.S. bond market, was a top contributor to performance. Additionally, an out-of-index position in high-yield credit, which outperformed investment-grade credit, further boosted results. • Our overweight position in the securitized sector also was a main contributor to performance. Our focus on credit-sensitive subsectors, including asset-backed securities, non-agency collateralized mortgage obligations, non-agency commercial mortgage-backed securities and collateralized loan obligations, drove the sector’s results. • Our allocation to emerging markets debt and an underweight in U.S. government securities also contributed to performance.

Interest rates increased and remained elevated to combat inflation, which gradually declined. Equities markets were generally strong during the period, due largely to enthusiasm for artificial intelligence. Concerns about the sturdiness of the U.S. economy led to a rotation into lower-volatility securities later in the period. • The fund’s higher positive delta — an estimate of how much the price changes for a derivative based on price movements for the underlying security — relative to the index throughout the 12-month period was the main contributor to the fund’s performance. • The fund’s focus on what we believe are higher-quality issuers added value and contributed to the fund’s performance throughout the period. • The fund’s lower duration relative to the index aided relative performance, particularly during the first eight months of the period when rates were rising.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? American Century Quality Diversified International ETF returned 20.91% for the reporting period ended August 31, 2024. The commentary below refers to the fund’s performance compared to the MSCI World ex USA Index. • Global stocks in developed markets outside the U.S. broadly advanced during the 12-month period. Enthusiasm for artificial intelligence helped propel global equities in the information technology sector. At the same time, stocks for health care companies involved in the development of new and promising pharmaceutical treatments to effectively treat obesity also gained. • Strategic stock selections in the consumer staples sector contributed to the fund’s performance. The fund is underweight in the food products industry, which was under pressure during the period, and avoiding exposure to Nestle helped drive results. • Information technology benefited from significant investments in AI, so the fund’s overweight position, combined with security selection in the sector, also contributed to performance. The semiconductors industry is a prime beneficiary of AI, so our overweight and stock picks in the space gave results a boost. • Holdings in the materials sector slowed performance. The fund is overweight in materials and security selection in the sector dampened results. Stock picks in the metals and mining industry weighed on performance as an overweight position in Fortescue was a key detractor during the period.

American Century Quality Preferred ETF returned 11.98% for the reporting period ended August 31, 2024. The fund seeks current income and capital appreciation. The commentary below refers to the fund’s performance compared to the ICE Exchange-Listed Preferred & Hybrid Securities Index. • Preferred securities gained during the period as bond yields fell. Inflation gradually cooled, as did economic growth during the latter half of the period. Equities were strong during the period due largely to enthusiasm for artificial intelligence. Concerns about AI investments and the sturdiness of the U.S. economy led to a rotation into lower-volatility securities later in the period. • Spreads narrowed during the 12-month period, which detracted from the fund’s relative performance. The fund’s allocation to institutional preferred securities also weighed on performance, given that exchange-traded preferred securities outperformed. • The fund’s short duration versus the index contributed to relative performance, particularly during the first eight months of the period when rates were rising. • The fund’s focus on what we believe are higher-quality issuers also gave performance a lift. Strong security selection in the utilities aided results as the sector broadly benefited from advancements in AI, which is expected to increase demand for electricity.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? American Century Select High Yield ETF returned 10.89% for the reporting period ended August 31, 2024. The fund seeks to provide high current income. The commentary below refers to the fund’s performance compared to the ICE BofA US High Yield Constrained (BB-B) Index. • Changing expectations for Federal Reserve (Fed) rate cuts led to Treasury market volatility during the period. But, as inflation slowly moderated and the labor market weakened, a Fed policy shift appeared imminent, and Treasury yields declined overall. High-yield earnings generally remained resilient, and high-yield bonds delivered solid gains for the period. • An underweight position versus the index in Rakuten Group, a Japan-based e-commerce company, weighed on results. The company reentered high-yield benchmarks in January and reported improvements. We remained cautious toward company management. • Exposure in the pharmaceuticals sector also detracted from results. Specifically, an underweight in specialty pharmaceutical and medical device company Bausch Health Cos., which rallied in May, weighed on performance. Uncertainties around the company’s plans to spin off its eye care business and concerns about liability management prompted our underweight. • Positioning in the support services sector aided results, largely due to our position in office supplies retailer Staples. The company extended its recovery via margin expansion and free cash flow improvements. A position in specialty chemicals company Solenis, which consistently reported strong operating performance and deleveraging progress, also boosted performance.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? American Century Short Duration Strategic Income ETF returned 7.98% for the reporting period ended August 31, 2024. The fund seeks income. As a secondary objective, the fund seeks long-term capital appreciation. The commentary below refers to the fund’s performance compared to the Bloomberg U.S. 1-3 Year Government/Credit Bond Index. • Treasury yields declined and inflation moderated for the 12-month period, which supported widespread gains across the U.S. fixed-income market. Credit-sensitive securities generally outperformed government securities for the period. Against this backdrop, our sector allocations broadly aided performance. • An overweight position versus the index in investment-grade credit, which outperformed the broader U.S. bond market, was a top contributor to performance. Additionally, an out-of-index position in high-yield credit, which outperformed investment-grade credit, further boosted results. • Our overweight position in the securitized sector also was a main contributor to performance. Our focus on credit-sensitive subsectors, including asset-backed securities, collateralized loan obligations, non-agency commercial mortgage-backed securities and non-agency collateralized mortgage obligations drove the sector’s results. • Our allocation to emerging markets debt and an underweight in U.S. government securities also contributed to performance.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? American Century Sustainable Equity ETF returned 24.77% for the reporting period ended August 31, 2024. The fund seeks long-term capital growth. The commentary below refers to the fund’s performance compared to the S&P 500 Index. • A risk-on environment over much of the 12-month period broadly favored large-cap stocks, particularly those related to artificial intelligence. This was despite elevated interest rates and worries about a recession that did not happen. Concerns about AI investment and slowing economic conditions led to a rotation to lower volatility and higher-quality stocks near the end of the period. • Positioning in the health care sector contributed most to performance. These stocks benefited from solid earnings growth and attractive valuations given uncertainty about the economy. Biotechnology stocks performed well amid a surge in innovation, which saw progress on treatments for some of mankind’s most intractable diseases, including drugs for obesity, Alzheimer’s and heart disease. • Stock choices in the information technology sector detracted most from performance compared with the benchmark. While our positioning among the so-called Magnificent Seven stocks was beneficial overall, we were underweight in select communications equipment, electronic equipment and semiconductor stocks, which benefited from investor focus on AI-related technology. • Energy stocks also detracted. Oil prices fell beginning in late 2023 because of uncertainty around the pace of global economic growth. That weighed on energy producers and equipment and services companies. Elsewhere, it hurt to be underweight real estate investment trusts, which rebounded during the period as investors began to anticipate Federal Reserve interest rate cuts.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? American Century Sustainable Growth ETF returned 28.41% for the reporting period ended August 31, 2024. The fund seeks capital appreciation. The commentary below refers to the fund’s performance compared to the Russell 1000 Growth Index. • A risk-on environment over much of the 12-month period broadly favored large-cap stocks, particularly those related to artificial intelligence. This was despite elevated interest rates and worries about a recession that did not happen. Concerns about AI investment and slowing economic conditions led to a rotation to lower volatility and higher-quality stocks near the end of the period. • Stock picks and an underweight in the industrials sector contributed most to the fund’s performance, led by positioning among ground transportation stocks. Consumer discretionary was another source of strength. Stock selection contributed, and it helped to be underweight this lagging sector. Both sectors were vulnerable to worries about a potential economic slowdown. • Stock choices in the information technology sector detracted most from performance compared with the benchmark. While our positioning among the so-called Magnificent Seven stocks was beneficial overall, we were underweight in select semiconductor, communications equipment and electronic equipment stocks, which benefited from investor focus on AI-related technology. • Financials stocks also detracted. Our choices among financial services stocks detracted most in the sector. We favored the stocks of electronic payment networks such as Visa, Mastercard and Block (formerly Square). Unfortunately, these companies were hit by worries about the effect on their business of a potential economic slowdown.

American Century U.S. Quality Growth ETF returned 27.27% for the reporting period ended August 31, 2024. The commentary below refers to the fund’s performance compared to the Russell 1000 Growth Index. • A risk-on environment over much of the 12-month period broadly favored large-cap stocks, particularly those related to artificial intelligence. This was despite elevated interest rates and worries about a recession that did not happen. Concerns about AI investment and slowing economic conditions led to a rotation to lower volatility and higher-quality stocks near the end of the period. • Consumer discretionary stocks contributed the most to performance. It helped to be underweight in electric vehicle maker Tesla specifically and the automobiles industry more broadly. High interest rates and worries about the economy meant many automakers resorted to price cuts to boost automobile sales. Elsewhere in the sector, select holdings among specialty retailers performed well. • Positioning in the information technology sector detracted most from relative performance. Semiconductor stocks, which benefited from investor focus on AI-related technology, performed very well. Unfortunately, two of the top three overall detractors were underweight positions in semiconductor companies NVIDIA and Broadcom.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? American Century U.S. Quality Value ETF returned 22.91% for the reporting period ended August 31, 2024. The commentary below refers to the fund’s performance compared to the Russell 1000 Value Index. • A risk-on environment during the period broadly favored large-cap stocks, particularly those related to artificial intelligence. This occurred despite elevated interest rates and worries about a recession that did not happen. Concerns about AI investment and slowing economic conditions led to a rotation toward lower volatility and higher-quality stocks near the end of the period. • Holdings in the information technology sector, for which the fund is overweight relative to the benchmark, contributed to performance during the 12-month period. Stock picks in the semiconductors industry buoyed results. Holdings in companies like Broadcom and Qualcomm aided performance, as did a lack of exposure to Intel, which posted disappointing earnings and suspended its dividend. • Allocation among names in the energy sector also contributed to the fund’s performance. Falling oil prices generally pressured stocks in the oil, gas and consumable fuels industry, so the fund’s underweight position and allocation among names in the industry helped results. Not owning names in the energy equipment and services industry also aided relative performance. • The fund’s underweight position relative to the benchmark in the financials sector curbed performance. Not owning large banks like JPMorgan Chase & Co., Bank of America and Wells Fargo & Co. weighed on results as shares in those institutions broadly advanced during the period. Underweight positions in the capital markets and insurance industries also detracted.

Avantis All Equity Markets ETF returned 21.16% for the reporting period ended August 31, 2024. The fund seeks long-term capital appreciation. The commentary below refers to the fund’s performance compared to the MSCI ACWI IMI. • Global stocks rallied for the 12-month period, which was characterized by weak economic growth, falling interest rates, moderating inflation and resilient corporate earnings results. Large-cap stocks generally fared better than small caps, and growth broadly outpaced value. • Overweight positions versus the benchmark in large-, mid- and smaller-cap companies, which underperformed, detracted from performance. An underweight to mega caps, which outperformed, also detracted from results. • The fund’s underweight in companies with the lowest combined profitability and book-to-market characteristics, which outperformed, weighed on performance. An overweight to companies with the highest profitability and book-to-market metrics, which underperformed, also detracted. • Country weightings aided performance, largely due to an overweight position in the U.S. and an underweight in France.

Corporate bonds generally outperformed the broad market, as economic growth and corporate earnings remained resilient and credit spreads tightened. • Yield curve positioning and asset allocation were the primary drivers of fund performance. The fund maintained a duration position in line with the benchmark’s. • The fund’s overweight to the corporate sector aided performance as credit spreads tightened during the 12-month period. • The fund’s positioning on the yield curve and exposure to bonds with higher carry and roll-down also contributed to performance.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? Avantis Core Municipal Fixed Income ETF returned 5.10% for the reporting period ended August 31, 2024. The fund seeks current income that is exempt from federal income tax. The commentary below refers to the fund’s performance compared to the S&P National AMT-Free Municipal Bond Index. • Aided by a late-2023 rally, municipal bonds generally delivered gains for the 12-month period. • The fund’s underweight duration positioning compared to the benchmark was the primary driver of performance. • To maintain exposure to the bonds with highest carry and roll-down, the fund primarily invested in bonds with less than 20 years to maturity. The underweight to bonds with maturities greater than 20 years detracted from performance. These bonds were the highest performing among the municipal cohort for the reporting period, given the broad rally in fixed income across the entire municipal bond curve.

The commentary below refers to the fund’s performance compared to the MSCI Emerging Markets IMI. • Against a backdrop of modest global growth and moderating global inflation, emerging markets (EM) stocks rallied for the 12-month period but lagged developed markets stocks. Within the EM universe, the value style broadly outperformed growth. • The fund’s overweight versus the index in companies with the highest profitability and book-to-market characteristics, which outperformed, contributed to performance. An underweight to companies with the lowest profitability and book-to-market characteristics, which underperformed, also aided results. • The fund’s underweight to mega-cap stocks, which outperformed for the period, detracted from results. Additionally, overweight exposure to mid- and small-cap stocks weighed on performance.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? Avantis Emerging Markets Small Cap Equity ETF returned 12.02% for the reporting period ended August 31, 2024. The fund seeks long-term capital appreciation. The commentary below refers to the fund’s performance compared to the MSCI Emerging Markets Small Cap Index. • Global stocks rallied for the fiscal year. Despite underperforming their developed markets peers, largely due to losses in China, emerging markets stocks broadly delivered solid gains. Within the emerging markets asset class, small-cap stocks generally outperformed large-cap stocks, and the value style outpaced growth. • Overweight positions versus the index in micro- and small-cap stocks weighed on results for the period from the fund’s inception through its August 31 fiscal year-end. Underweight positions in mid-, large- and mega-cap stocks also detracted. • Country exposure detracted from performance. Specifically, an overweight position in China and an underweight in India weighed on results. • The fund’s emphasis on stocks with high profitability and book-to-market characteristics aided performance. Similarly, its focus on underweighting companies with unattractive profitability and book-to-market metrics lifted results.

The commentary below refers to the fund’s performance compared to the MSCI Emerging Markets IMI Value. • Against a backdrop of modest global growth and moderating global inflation, emerging markets (EM) stocks rallied for the 12-month period but lagged developed markets stocks. Within the EM universe, the value style broadly outperformed growth. • The fund’s overweight versus the index in companies with the highest combined profitability and book-to-market characteristics, which outperformed for the period, contributed to performance. An underweight to companies with the lowest profitability and book-to-market traits, which underperformed, also boosted results. • The fund’s underweight position in mega-cap stocks, which outperformed, and overweight in smaller-cap stocks, which underperformed, detracted from performance.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? Avantis Moderate Allocation ETF returned 16.68% for the reporting period ended August 31, 2024. The fund seeks long-term capital appreciation. The commentary below refers to the fund’s performance compared to the custom index, which consists of 65% MSCI ACWI IMI/35% Bloomberg U.S. Government/Credit 1-5 Year Index. • Global stocks rallied for the 12-month period, which was characterized by weak economic growth, falling interest rates, moderating inflation and resilient corporate earnings results. Against this backdrop, U.S. stocks delivered solid gains but lagged global stocks. • Within the fund’s equity portfolio, overweights versus the index in large-, mid- and smaller-cap stocks, which underperformed, weighed on results. An underweight position in mega caps, which outperformed, also detracted. • The fund’s underweight in companies with the lowest combined profitability and book-to-market characteristics, which outperformed, weighed on performance. An overweight to companies with the highest profitability and book-to-market metrics, which underperformed, detracted modestly. • Within the fixed-income component, an overweight to the corporate sector aided performance as credit spreads tightened during the 12-month period. The fund’s positioning on the yield curve and exposure to bonds with higher carry and roll-down also contributed to performance.

The fund’s overweight to companies with the highest profitability and book-to-market traits, which outperformed, also aided results. • Overall, country exposure contributed to performance, mainly due to overweight positions in Taiwan and India and avoiding Saudi Arabia.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? Avantis Short-Term Fixed Income ETF returned 6.74% for the reporting period ended August 31, 2024. The fund seeks to maximize total return. The commentary below refers to the fund’s performance compared to the Bloomberg U.S. Government/Credit 1-5 Year Index. • Treasury yields declined and inflation moderated for the 12-month period, which supported widespread gains across the U.S. fixed-income market. However, credit spread performance was somewhat mixed among short-dated corporate bonds. Credit spreads widened for bonds with less than two years to maturity and tightened for bonds with maturities between three to five years. • Duration positioning and asset allocation were the primary drivers of fund performance. • The fund’s overweight versus the benchmark to the corporate sector aided performance. The fund’s positioning on the yield curve across various maturities also contributed to performance. • To maintain exposure to the bonds with highest carry and roll-down, the fund maintained a duration slightly shorter than the benchmark’s. This detracted from performance.

Within the EM universe, the value style broadly outperformed growth. • The fund’s overweight versus the index in companies with the highest profitability and book-to-market characteristics, which outperformed, contributed to performance. An underweight to companies with the lowest profitability and book-to-market characteristics, which underperformed, also aided results. • The fund’s underweight to mega-cap stocks, which outperformed for the period, detracted from results. Additionally, overweight exposure to mid- and smaller-cap stocks weighed on performance.

The commentary below refers to the fund’s performance compared to the MSCI World ex USA IMI. • Non-U.S. developed markets stocks rallied for the 12-month period, which was characterized by weak global growth, falling interest rates, moderating inflation and resilient corporate earnings results. Large-cap stocks generally fared better than small caps, and value broadly outpaced growth. • Performance across book-to-market and profitability quartiles was mixed. The fund’s underweight versus the index in companies with the lowest combined profitability and book-to-market characteristics contributed to performance. The fund's overweight to the highest profitability and book-to-market companies detracted from results. • Avoiding real estate investment trusts, which underperformed for the period, modestly aided results. • The fund’s underweight to mega-cap stocks, which outperformed for the period, detracted from performance. Additionally, overweights to mid- and small-cap stocks, which underperformed, weighed on results.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? Avantis International Equity Fund G Class returned 19.14% for the reporting period ended August 31, 2024. The fund seeks long-term capital appreciation. The commentary below refers to the fund’s performance compared to the MSCI World ex USA IMI. • Non-U.S. developed markets stocks rallied for the 12-month period, which was characterized by weak global growth, falling interest rates, moderating inflation and resilient corporate earnings results. Large-cap stocks generally fared better than small caps, and value broadly outpaced growth. • Performance across book-to-market and profitability quartiles was mixed. The fund’s underweight versus the index in companies with the lowest combined profitability and book-to-market characteristics contributed to performance. The fund's overweight to the highest profitability and book-to-market companies detracted from results. • Avoiding real estate investment trusts, which underperformed for the period, modestly aided results. • The fund’s underweight to mega-cap stocks, which outperformed for the period, detracted from performance. Additionally, overweights to mid- and small-cap stocks, which underperformed, weighed on results.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance?

The commentary below refers to the fund’s performance compared to the Bloomberg U.S. Government/Credit 1-5 Year Index. • Treasury yields declined and inflation moderated for the 12-month period, which supported widespread gains across the U.S. fixed-income market. However, credit spread performance was somewhat mixed among short-dated corporate bonds. Credit spreads widened for bonds with less than two years to maturity and tightened for bonds with maturities between three to five years. • Duration positioning and asset allocation were the primary drivers of fund performance. • The fund’s overweight versus the benchmark to the corporate sector aided performance. The fund’s positioning on the yield curve across various maturities also contributed to performance. • To maintain exposure to the bonds with highest carry and roll-down, the fund maintained a duration slightly shorter than the benchmark’s. This detracted from performance.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? Avantis U.S. Equity Fund Institutional Class returned 23.72% for the reporting period ended August 31, 2024. The fund seeks long-term capital appreciation. The commentary below refers to the fund’s performance compared to the Russell 3000 Index. • U.S. stocks rallied for the 12-month period, which was characterized by resilient economic growth, falling Treasury yields, moderating inflation and generally healthy corporate earnings results. Within the U.S. market, stocks of companies with the largest market capitalizations broadly outperformed their smaller peers, while growth and value styles were mixed. • Against this backdrop, the fund’s underweight versus the index in mega-cap stocks, which outperformed, weighed on results. Overweight positions in large-, mid-, small- and micro-cap stocks also detracted from results. • The fund’s sector weightings modestly detracted, largely due to an overweight to energy and an underweight to information technology. • The fund’s underweight to companies with the lowest profitability and book-to-market characteristics and overweight to companies with the highest profitability and book-to-market traits aided performance. Avoiding real estate investment trusts, which underperformed for the period, modestly boosted results.

Factors Affecting Performance [Text Block]			What were the key factors that affected the fund’s performance? Avantis U.S. Small Cap Value Fund Institutional Class returned 19.76% for the reporting period ended August 31, 2024. The fund seeks long-term capital appreciation. The commentary below refers to the fund’s performance compared to the Russell 2000 Value Index. • U.S. stocks rallied for the 12-month period, which was characterized by resilient economic growth, falling Treasury yields, moderating inflation and generally healthy corporate earnings results. Within the small-cap universe, value stocks broadly outperformed their growth-stock counterparts. • Against this backdrop, the fund’s focus on companies with the highest combined profitability and book-to-market characteristics contributed to performance. An underweight position versus the index in the lowest profitability and book-to-market companies also boosted results. • An overweight position in small- and mid-cap stocks and an underweight in micro-cap stocks aided results. Avoiding real estate investment trusts, which underperformed for the period, also contributed to performance.
