Baron Discovery Fund returned 10.96% in 2025, trailing the Russell 2000 Growth Index by 2.05% due to market preference for low-quality, momentum-driven stocks over the fund's high-quality, long-term holdings. The fund's systematic approach focuses on competitively advantaged companies with significant growth potential, maintaining concentrated positions in software, healthcare, and defense sectors. Key contributors included Exact Sciences, which received a buyout offer from Abbott Laboratories, and Establishment Labs, benefiting from successful U.S. market penetration of innovative breast implants. The managers remain optimistic about 2026 prospects, citing favorable economic conditions including declining inflation, massive AI infrastructure investment, deregulation, GDP growth, and Federal Reserve rate cuts. Despite short-term headwinds from quality factor underperformance and AI disruption concerns in software, the fund maintains conviction in its anti-momentum strategy and expects the market environment to become more favorable for their disciplined, research-driven investment process.
The fund employs a systematic, long-term growth investing approach focused on competitively advantaged, well-managed companies with large untapped market opportunities, targeting 15% compounded returns through disciplined research and risk management processes.
We are extremely optimistic regarding the prospects for each holding in the Fund, and we look forward to a high growth, low inflation set-up for the 2026 economy.

| TICKER | COMMENTARY |
|---|---|
| CWAN | With Clearwater, the market was overly focused on the debt and large acquisitions while missing how core Clearwater was growing strongly still and had a tailwind from rate cuts. Clearwater Analytics ended getting bought out and would've netted me a large gain but in the meantime due to the size of the position I took and the options leverage, the weak performance was causing me to question my conviction until I decided to sell my position for a 30% loss, 2 weeks before the buyout news came through. |
| CWST | The fortunes of Casella Waste Systems waxed and waned during the quarter. At the beginning of the quarter, Casella's shares slipped ahead of its fiscal quarterly report. After showing revenues and earnings higher than anticipated, along with better full-year guidance, its share price recovered and ended the quarter up 3% for this provider of solid waste collection, transfer, disposal, and recycling services for residential, commercial, municipal, and industrial customers. |
| DKNG | If you want to place some action on a college football game or an NFL team, you can do so legally in 38 states through online sportsbooks such as DraftKings, FanDuel, or Hard Rock |
| DT | Dynatrace detracted from relative quarterly performance |
| ESTA | Establishment Labs sells next-generation Motiva breast implants that have meaningfully lower safety risks and aesthetic benefits compared to competitors. In particular, Motiva implants cause significantly less capsular contracture (where surrounding tissue squeezes the implant) and no known cancer risks. Motiva also comes in a more natural Ergonomix shape with a natural-feeling softer fill as well as potentially a smaller implant scar. The company's implants have captured significant share in many international markets, and the U.S. launch is now underway and progressing well, having already captured about 20% of U.S. aesthetic breast augmentation market. |
| EXAS | Exact Sciences Corp. is a cancer diagnostics company best known for Cologuard, its at-home screening test for colorectal cancer. The stock initially rose during the quarter on signs of reinvigorated growth and the introduction of a new test that drove revenue higher. Performance was further boosted in November when Abbott announced plans to acquire Exact Sciences at a significant premium. |
| FROG | Lastly was JFrog Ltd., the portfolio's strongest performer this quarter. JFrog manages the software supply chain and enables organizations to securely deliver software updates across their enterprises. Demand for security increased following the recent NPM supply chain attack. JFrog's security add-on—which secures open-source packages before organizations onboard them—has seen significant pipeline growth, driving a 32% rally in its shares. |
| GCI | During the quarter, we initiated a position in GCI Liberty, Inc. GCI is the leading broadband cable provider in Alaska. GCI generates revenue from broadband and wireless services. Roughly 97% of the Alaskans live within GCI's network footprint and about 80% have access to high-speed tiers (2.5 Gbps+). We estimate that GCI has 70% to 80% market share of high-speed broadband in Alaska. However, our decision to invest in GCI extends beyond the attractive free cash flow characteristics. A guiding principle of the firm is we invest in people and GCI offers the opportunity to participate in one of the final acts of John Malone's legendary career. |
| GTLB | We initiated a new investment position in GitLab (GTLB), a Dev/Sec/Ops software platform vendor that helps software developers plan, build, and monitor code for new and existing applications. The stock has been under severe pressure for some time, largely due to the belief that AI-powered 'Vibe Coding' software companies will displace GTLB solutions. We fundamentally reject this thesis and believe that as software development becomes easier and more productive, more code will be generated, increasing the need for planning, development, and monitoring tools like GitLab's. We estimate GTLB's intrinsic value is $75 per share. |
| LLYVA | Liberty Live Holdings, Inc. was a detractor during the period. Shares traded sharply lower following Live Nation's third quarter earnings release. During the quarter, concert segment earnings fell short of investor expectations, a divergence from a string of significant earnings beats in the business line. Management also lowered its outlook for ticketing in 2026 due to measures taken in response to regulatory action around ticket buying bots and costs associated with the FTC lawsuit. |
| PRMB | Longtime portfolio holding Primo Brands (PRMB), saw its stock price cut in half. We acquired PRMB back in 2020. We like the water delivery business, we believe it exhibits all the traits we look for in a quality business. In 2025, the company decided to accelerate the integration and pull forward the cost savings. This proved to be a poor decision and during the summer of 2025 the company faced several logistical challenges with late or missed deliveries and subscription cancellations. This was exacerbated by a tornado that damaged one of their critical bottling plants in Texas. We believe the business is on track to deliver on all its opportunities from the combination and the current stock price represents an excellent investment opportunity. |
| RGEN | RGEN shares rallied as the bioprocessing market showed signs of stabilization and renewed demand for its life sciences tools. |
| TREX | Trex is a US-listed supplier of outdoor composite decking and is currently experiencing an extended downturn in repair-and-remodel demand. In addition to a weaker-than-expected sales trajectory, in November the company unexpectedly announced incremental investment in sales and marketing for FY26 which will meaningfully impact profit margins. Notably, this followed the acquisition of its closest peer, AZEK, by James Hardie, suggesting the incremental investment may be defensive in nature. |
| VRNS | security software company Varonis and Wix.com, a website and application creation platform, both of which had minor disappointments that led to material stock price overreactions. We continue to have conviction in the idiosyncratic growth opportunities at each of these profitable and attractively valued businesses, both of which can benefit from the proliferation of AI adoption. |
| WAY | We initiated a position in Waystar Holding Corp., which provides a full spectrum of revenue cycle management software to health care providers. The company services 30,000 clients, representing over 1 million distinct providers. And it processes 6 billion transactions per year, including over $1.8 trillion in annual gross claims which span about 50% of all U.S. patients. The software smooths the claims process in three distinct areas: (1) Intake (insurance eligibility checks, cost estimation, prior-authorization approval and co-pay collection); (2) Clinical Visitation (documentation integrity, showing medical necessity, accuracy of documentation and coding); and (3) Post Care (clean claim submission, claim monitoring, patient payments, denial/appeal, and payor remittance). |
