Baron Partners Fund declined 5.33% in Q1 2026 but outperformed its Russell Midcap Growth benchmark which fell 6.35%. The fund's concentrated portfolio continues to be led by SpaceX at 33% weighting, which appreciated 24.5% following its merger announcement with xAI, creating a combined $1.25 trillion valuation. However, many portfolio companies faced pressure from AI disruption concerns, with customers delaying large deals pending clarity on AI impact. This affected holdings across sectors including FactSet, Gartner, and CoStar. Tesla also declined on concerns about increased capex spending exceeding $20 billion in 2026, though management believes this investment will solidify competitive advantages and enable autonomous driving progress. The managers maintain conviction in their concentrated approach, noting similar periods where reinvestment cycles initially pressured performance before delivering strong returns. They expect current depressed valuations to contribute positively once AI concerns resolve and major investment initiatives bear fruit. The fund's long-term track record remains strong with 17.45% annualized returns since 2003 conversion.
Concentrated portfolio of high-quality growth businesses with sustainable competitive advantages trading at attractive prices despite temporary headwinds from AI disruption concerns and reinvestment cycles.
Manager expects growth trends to improve as AI disruption concerns resolve and companies complete major investment cycles. Believes current depressed valuations in AI-affected holdings will contribute to future performance once negative sentiment shifts and earnings initiatives are realized.

| TICKER | COMMENTARY |
|---|---|
| TSLA | Tesla, Inc. designs, manufactures, and sells fully 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 (FSD) 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. |
| CSGP | 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. |
| IT | 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. |
| FDS | FactSet, a leading provider of investment management tools, has continued to be under pressure due to a combination of industry-wide concerns about AI and management transition. We maintain conviction in FactSet due to the large addressable market, sticky customer base (95%-plus retention rates), consistent execution on both new product development, financial results, and robust free cash flow generation. The most recent results have exceeded investors' expectations for revenue growth, free cash flow generation, and stock repurchases. As clients utilize AI, they are becoming more (not less) reliant on FactSet's trusted and high-quality data sets. This value makes the company less dependent on seat-based contracts, which has been reduced to less than 20% of annual subscription value (ASV). We continue to believe that new CEO Sanoke Viswanathan is a highly capable leader who is focused on reaccelerating growth and driving a stronger sense of urgency across the organization. |
| CHH | 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. |
| ACGL | Specialty insurer Arch Capital Group Ltd. contributed to performance as property and casualty (P&C) insurance stocks broadly outpaced the market amid heightened volatility. P&C insurance stocks tend to be resilient during turbulent markets and are less exposed to the AI-related concerns weighing on other sectors. In addition, Arch reported better-than-expected quarterly earnings, and management expects a continuation of double-digit growth in book value per share. We continue to own the stock due to Arch's strong management team and our expectation of continued growth in earnings and book value over time. |
