Dear Baron First Principles ETF ^® Shareholder,

Performance

Baron First Principles ETF ^® ((the Fund)) had a disappointing start to 2026, with a decline of 8.51% (NAV) compared with a 9.54% loss for the Russell 3000 Growth Index ((the Benchmark)). The declines were due to continued concerns about the effects of AI on many businesses throughout the portfolio as well as worries about the impact of the Iran war on inflation, interest rates, and consumer spending. These declines were partially offset by Space Exploration Technologies Corp. (SPACE) (SpaceX) and its deal to acquire X. AI Holdings Corp. (X.AI) (xAI), which resulted in the revaluation of the combined business at a significantly higher enterprise value.

While we are disappointed with the start of the year, we continue to see opportunities throughout the portfolio. Our portfolio companies continue to do quite well and are generating strong growth and cash flow for additional investments in their businesses to accelerate growth further with excess cash being returned to shareholders through share buybacks and dividends.

Our companies all have strong balance sheets with many operating with financial leverage below their targeted levels, giving them additional liquidity to lever up and buy back more stock should they desire.

Many stocks in the portfolio are now trading at historically low valuations, and we believe there is a disconnect between where these businesses trade today and what they can become over time. As a result, this past quarter we saw an accelerated rate of insider purchases from executives and directors at Verisk Analytics, Inc. (VRSK) , Birkenstock Holdings plc, Vail Resorts, Inc. (MTN) , FactSet Research Systems Inc. (FDS) , and MSCI Inc. (MSCI) When we see these insider purchases, it gives us further confidence in our investment theses for these growth businesses and reinforces our belief that valuations are attractive. As a result, during the quarter we increased our positions in many of these stocks while adding a couple of new names as well. We are continuing to make sure the portfolio remains focused while being cognizant that positions are appropriately sized for risk in this concentrated Fund.

.

We believe this combination of strong revenue growth with well-positioned balance sheets and attractive valuations offers multiple avenues for potential returns for investors. As a result, we view the portfolio as compelling, with a favorable risk/reward profile.

Further, we believe there is still a ton of capital remaining on the sidelines waiting to be invested, including private equity firms who continue to raise new funds. We believe as rates continue to move lower over the next year, public to private transactions and strategic acquisitions should accelerate, which should further support valuations and our investments.

We continue to believe these businesses have strong competitive advantages with underpenetrated growth opportunities ahead of them and robust balance sheets to finance their growth.

While it is only the Fund’s first full quarter of performance, we believe the Fund should generate significant excess returns over time with much less than market risk. This is due to the balanced nature of the portfolio with approximately 35% invested in high-growth disruptive investments that can generate revenue growth of as much as 20% to 30%; between 15% and 20% of the portfolio in real irreplaceable assets that trade at significant discounts to replacement cost and where they would sell to private equity or another strategic buyer; between 20% and 25% in financials businesses, many of which are financial data providers that have recurring revenue and earnings given the embedded nature of their products in the workflow of their customers; and the balance in core double-digit revenue growing businesses that are more mature in their lifecycle and generate earnings growth while using excess cash for dividend increases, share buybacks, and additional investments in the business to accelerate growth further.

Total returns by investment type for the quarter

Total returns by investment type for the quarter

Aside from two of our private investments, SpaceX and xAI successfully completing their combination at a valuation significantly higher than previous marks, performance in the first quarter was hurt by continued concerns about the introduction of AI into the economy and those businesses that could be impacted most from the new competition. These included our subscription-based software and platform investments such as Spotify Technology S. A. , FactSet, and Guidewire Software, Inc. However, while the increased competition hurt the valuation of these stocks in the quarter, it has not impacted financials, and these companies continue to generate strong revenue growth and margins in line with company and investor expectations.

Further losses were seen in our exposure to consumer-focused investments given worries about the escalation of the war in Iran and what that could mean for inflation, interest rates, and consumer spending. These included companies such as Red Rock Resorts, Inc. , Hyatt Hotels Corporation , and On Holding AG . However, despite worries about the war and its impact on the consumer, these companies continue to do quite well as the consumer remains resilient despite macro concerns.

Global digital music streaming platform Spotify declined by 17.4% in the first quarter and detracted 77 bps from performance as investors were concerned about the impact AI music could have on the conversion of free subscribers to paying subscribers as well as how it could impact time on the platform. In addition, further concerns about the timing of price increases and resulting margin expansion also frustrated investors. However, the company continues to institute price increases across multiple regions and complete negotiations with major record labels. User growth remains strong growing at a double-digit rate with high engagement and low churn even with price increases. The company remains on a path to increase gross margins through its high-margin artist promotions marketplace, growing podcast contribution, and ongoing investments in advertising where revenue growth is expected to accelerate this year. We continue to view Spotify as a long-term winner in music streaming with potential to reach 1 billion-plus subscribers by 2030.

Property and casualty (P&C) insurance software vendor Guidewire declined 24.7% in the first quarter and detracted 84 bps from performance. The declines were due to continued AI concerns and potential future competition. However, the company continues to do quite well and after a multi-year transition period, the company’s cloud transition is substantially complete, and insurers are upgrading to the cloud at an accelerated rate. We believe that cloud will be the sole path forward, with annual recurring revenue (ARR) benefiting from new customer wins and migrations of the existing customer base to the company’s Insurance Suite Cloud. We also expect the company to shift R&D resources to product development from infrastructure investment, which should help drive cross-sales into its sticky installed base and potentially accelerate ARR over time. We are encouraged by Guidewire’s subscription gross margin expansion, which improved by approximately 580 bps in its most recently reported quarter. We believe Guidewire will be the critical software vendor for the global P&C insurance industry, capturing 30% to 50% of its $15 billion to $30 billion total addressable market and generating margins above 40%.

Shares of global hotelier Hyatt declined 8.6% and hurt performance by 34 bps in the first quarter as investors were concerned with a potential deceleration in revenue per available room (RevPAR) growth due to the Middle East conflict as well as cartel uprisings in Mexico that could hurt travel to those parts of the world. However, according to Hyatt management, the Middle East is only 3% of total fees and Mexico, while it represents approximately 7% of global rooms, is seeing travelers switch and rebook for other places including its Caribbean properties. There has been no impact on unit growth, and the company still expects to grow units between 6% and 7% this year. We believe this growth combined with low single-digit RevPAR growth and slight margin improvement should lead to double-digit EBITDA growth this year. This should generate strong free cash flow, which the company can use for further share buybacks and reinvestment back into the business. The company still has a strong investment grade balance sheet with 90% of the business coming through fees that should allow them to overcome any short-term outside disruptions to its business. Hyatt trades at a discount to peers despite a similar growth and mix of business. We believe this discount should narrow over time as investors see the continued growth and resilience of its business model.

Shares of Las Vegas Local casino operator, Red Rock Resorts, declined 11.2% in the first quarter and hurt performance by 44 bps as investors were concerned with a potential slowdown in Las Vegas gaming revenue brought about by the macro uncertainty from the war in Iran. Combine this slowdown with construction disruption due to many renovation and expansion projects occurring at its properties and current earnings could decelerate. However, the company continues to spend at its resorts as management sees further opportunities for growth from continued population growth and a higher net worth individual coming to Las Vegas. The company continues to generate strong cash flow that should produce accelerated growth in the coming years. We continue to believe the stock remains attractively valued as the company’s founders recently bought stock at current levels giving us further confidence in the company’s accelerated growth prospects.

Top contributors to performance for the quarter

Space Exploration Technologies Corp. (SpaceX) is a high-profile private company founded by Elon Musk. The company’s primary focus is on developing and launching advanced rockets, satellites, and spacecrafts, with the ambitious long-term goal of making life multi-planetary. SpaceX is generating significant value with the rapid expansion of its Starlink broadband service. The company is successfully deploying a vast constellation of Starlink satellites in Earth’s orbit, reporting substantial growth in active users, and regularly deploying new and more efficient hardware technology. Furthermore, SpaceX has established itself as a leading launch provider by offering highly reliable and cost-effective launches, leveraging the company’s reusable launch technology. SpaceX capabilities extend to strategic services such as human spaceflight missions. Moreover, SpaceX is making tremendous progress on its newest rocket, Starship, which is the largest, most powerful rocket ever flown. This next-generation vehicle represents a significant leap forward in reusability and space exploration capabilities. We value SpaceX using prices of recent financing transactions.

FIGS, Inc. designs and sells scrubwear for health care professionals through a digitally native, direct-to-consumer strategy. Shares rose following robust fourth-quarter results and upbeat 2026 guidance. Revenue expanded 33% to $201.9 million, reflecting broad-based momentum across categories and geographies and exceeding expectations. Holiday demand was strong throughout the season and remained elevated through quarter-end. U. S. revenue rose 28.7% to $164.2 million, while international revenue accelerated 55% to $37.7 million, with scrubs and non-scrubwear contributing gains of 35% and 26%, respectively. This topline strength translated to profitability, with EBITDA rising 29.8% to $26.7 million. Building on this momentum, revenue is expected to grow in the low-20% range in the first quarter and 10% to 12% for the full year. Additional drivers include accelerating international expansion, new store openings (both the ramping 2025 cohort and four locations planned for 2026), and continued traction in TEAMS (FIGS’ enterprise and group ordering business). The company maintains a strong balance sheet, with no debt and roughly $300 million in cash and marketable securities.

Global hotel franchisor Choice Hotels International, Inc. contributed to performance during the quarter as the company saw a slight acceleration in revenue per available room across its portfolio. Choice continues to grow units at a low-single-digit rate and is benefiting from higher royalty rates on new franchise contracts, driving mid-single-digit growth in earnings and free cash flow. The company is using this cashflow to return capital through share repurchases. We continue to believe the stock offers compelling value, trading at a roughly five multiple-point discount to its historical average. Choice maintains a strong balance sheet, providing flexibility for additional share buybacks, particularly when the stock trades below the company’s view of intrinsic value. Choice’s steady growth profile, both domestically and internationally, should further support attractive shareholder returns over time.

Top detractors from performance for the quarter

Tesla, Inc. designs, manufactures, and sells fully electric vehicles (EVs), solar products, and energy storage solutions, while developing advanced real-world AI technologies. Following robust gains in late 2025, shares fell as investors awaited progress on robotaxis and assessed the company’s sizable investments in manufacturing and AI. Operationally, Tesla delivered strong quarterly results amid a challenging EV environment. Automotive gross margins improved sequentially and beat expectations, the energy storage business maintained robust momentum with best-in-class margins, and battery cell production ramped. The company continues to advance its AI and autonomous driving initiatives at a rapid pace. Management anticipates meaningful robotaxi expansion in 2026 and continues to finalize the Optimus Gen 3 design and build out large-scale manufacturing capacity for humanoid robots. Tesla is also releasing major Full Self-Driving enhancements, scaling AI training compute, and deepening vertical integration in semiconductor design and production. These initiatives, while increasing near-term capital spending, underscore Tesla’s pivot toward becoming a leader in physical AI.

CoStar Group, Inc. is the leading provider of information and marketing services to the commercial and residential real estate industries. Shares fell due to multiple compression driven by rising AI fears. The market has come to view AI as an existential risk for a growing number of industries—including software, business services, information services, and video games—despite no evidence of any fundamental impact to these sectors. This “shoot first and ask questions later” dynamic has resulted in meaningful share price declines. We continue to own CoStar given its differentiated data assets and significant growth opportunities in providing enhanced real estate information, analytics, and marketplace offerings. CoStar boasts an enviable business model with high levels of recurring revenue and meaningful cash flow generation potential. While near-term cash flow is obscured by elevated investment in Homes. com, we expect spending to moderate and cash flow to improve over the next several years. The company also maintains a substantial cash balance, which we are hopeful will be used to aggressively repurchase shares at current depressed valuation levels.

Syndicated research provider Gartner, Inc. detracted from performance as valuation multiples compressed amid rising concerns around AI. Investors have increasingly viewed AI as a potential existential risk across a widening range of industries—including software, business services, information services, and video games—despite no evidence of any fundamental impact to these sectors. This “shoot first and ask questions later” dynamic has driven meaningful share price declines across the group. Against this backdrop, shares of Gartner came under pressure after the company reported contract value growth that was just 0.5% below expectations, underscoring the dramatic valuation compression at play. We continue to own Gartner given its large addressable market, significant competitive advantages, and robust free cash flow generation, which we expect management to deploy toward share repurchases at depressed valuation levels. We also view Gartner as an AI beneficiary, as it can leverage emerging tools to extract deeper insights from its vast trove of proprietary data and deliver it to customers in chatbot-type formats that meaningfully enhance its value proposition.

Portfolio Structure

We are steadfast in our commitment to long-term investing in competitively advantaged, growth businesses. We run a balanced portfolio of uncorrelated businesses to help reduce portfolio risk. We believe this portfolio strategy is an effective way to mitigate risk and increase the purchasing power of your savings. While there will always be market volatility, we believe we can reduce that volatility via this portfolio due to its balanced nature.

As of March 31, 2026, the Fund owned 24 investments. From a quality standpoint, the Fund’s investments have generally strong long-term sales growth and margins with the ability to possibly double earnings and cash flow over the next four to five years. Many of our portfolio companies generate recurring earnings and cash flow with low churn rates giving them enhanced visibility into growth and significant pricing power. Many of our portfolio companies continue to invest in their businesses to accelerate growth further. While this hurts current margins, we believe they should generate strong returns on invested capital, and the investments will accelerate further growth in the future.

While focused, the Fund is diversified by sector. The Fund’s weightings are significantly different than those of the Benchmark. For example, the Fund is heavily weighted to Consumer Discretionary businesses with 35.6% of its net assets in this sector versus 12.9% for the Benchmark. The Fund has no exposure to Energy, Materials, or Utilities. We believe companies in these sectors can be cyclical, linked to commodity prices, and/or have little if any competitive advantage. The Fund also has lower exposure to Health Care stocks at 1.9% versus 8.4% for the Benchmark. The performance of many stocks in the Health Care sector can change quickly due to exogenous events or binary outcomes (e. g. , biotechnology and pharmaceuticals). As a result, we do not invest a large amount in these stocks in this focused portfolio. In Health Care, we invest in competitively advantaged companies that are leaders in their industries such as IDEXX Laboratories, Inc. , the leading provider of diagnostics to the veterinary industry and who is benefiting from the increase in pets that people acquired during the COVID pandemic, especially as these pets age. The Fund is further diversified by investments in businesses at different stages of growth and development.

Disruptive Growth Companies

Disruptive Growth firms accounted for 35.8% of the Fund’s net assets. On current metrics, these businesses may appear expensive; however, we think they will continue to grow significantly and, if we are correct, they have the potential to generate exceptional returns over time. Examples of these companies include EV leader Tesla, Inc. , commercial satellite and launch company, Space Exploration Technologies Corp. , and audio streaming service provider Spotify Technology S. A. These companies all have large underpenetrated addressable markets and are well financed with significant equity stakes by these founder-led companies, giving us further conviction in our investment.

Core Growth Investments

Core Growth investments, steady growers that continually invest in their businesses for growth and return excess cash-flow to shareholders, represented 24.7% of net assets. An example would be FIGS, Inc. , the largest provider of scrubs and other attire to health care workers. The company continues to add new customers and increase the level of spending per customer as they add new articles of clothing and open new stores both domestically and abroad. This has allowed them to grow their addressable market and improve client retention and cash flow. FIGS continues to invest its cash flow in its business to accelerate growth further, which we believe should generate strong returns over time.

Financials Investments

Financials investments accounted for 23.9% of the Fund’s net assets. These businesses generate strong recurring earnings through subscriptions and premiums that generate highly predictable earnings and cash flow. These businesses use cash flows to continue to invest in new products and services, while returning capital to shareholders through share buybacks and dividends. These companies include Arch Capital Group Ltd. , FactSet Research Systems Inc. , and MSCI Inc.

Investments with Real/Irreplaceable Assets

Companies that own what we believe are Real/Irreplaceable Assets represent 15.5% of net assets. Vail Resorts, Inc. , owner of the premier ski resort portfolio in the world, upscale lodging brand Hyatt Hotels Corporation , and Red Rock Resorts, Inc. , the largest player in the Las Vegas Locals casino gaming market, are examples of companies we believe possess meaningful brand equity and barriers to entry that equate to pricing power over time.

Portfolio Holdings

As of March 31, 2026, the Fund’s top 10 holdings represented 64.9% of net assets. We have a long history of investing in many of these businesses across the Firm and believe they continue to offer significant appreciation potential, although we cannot guarantee that will be the case.

The top five positions in the portfolio, Tesla, Inc. , Space Exploration Technologies Corp. , MSCI Inc. , Shopify Inc. , and Verisk Analytics, Inc. , all have, in our view, significant competitive advantages due to strong brand awareness, technologically superior industry expertise, or exclusive data that is integral to their operations. We think these businesses cannot be easily duplicated and have large market opportunities to penetrate further, which enhances their potential for superior earnings growth and shareholder returns.
