SpaceX is generating significant value through rapid expansion of Starlink broadband service and establishing itself as a leading launch provider with reusable technology. The company is making tremendous progress on Starship, the largest most powerful rocket ever flown, representing a significant leap forward in space exploration capabilities. Eli Lilly's portfolio of Mounjaro/Zepbound GLP-1/GIP drugs are important treatments for diabetic and non-diabetic obese patients. This drug class should become the standard of care for both diabetes and obesity and grow to at least a $150 billion category. The market is in early innings of uptake with adoption driving Lilly to nearly double revenues by 2030. Microsoft has built a $135 billion run-rate cloud business including Azure cloud infrastructure and Office 365 applications. The company remains well positioned across overlapping software, cloud computing, and AI landscapes with its vertically integrated technology stack and broad sales distribution, driving durable long-term double-digit growth. NVIDIA has been more than a 10-bagger for the Fund, with Baron being early investors over four years before the ChatGPT moment. Broadcom has been a 2.5-bagger resulting from explosive growth not multiple expansion. These investments represent successful positioning in the infrastructure layer of AI computing. Spotify continues to demonstrate double-digit user growth and industry-leading engagement levels with evident pricing power as customer retention held despite recent price hikes. The company is on a path to structurally higher gross margins aided by high-margin artist-promotions marketplace and scaling podcast offering, with potential to reach over 1 billion monthly active users. | View | |

The consumer remains quite resilient despite concerns about higher inflation, interest rates, and tighter labor market. Consumer-oriented investments including FIGS, Hyatt Hotels, and On Holding showed strength in the quarter. The fund sees continued resilience in consumer demand for health care apparel and premium products.

The fund views Tesla as a disruptive growth company with large underpenetrated addressable markets, well financed with significant equity stakes by founder-led management giving further conviction in the investment. | DUOL CSGP SPOT ONON H FIGS GWRE |

| 2025 Q4 | Jan 22, 2026 | Sands Capital Technology Innovators Fund | 6.2% | 14.7% | AMZN, APP, ASML, AVGO, AXON, CPNG, CVNA, DASH, DDOG, DUOL, GOOGL, IOT, MELI, META, MSFT, NFLX, NOW, NU, NVDA, PANW, PLTR, RBLX, SE, SHOP.TO, SPOT, SQ, TEAM, TSM, V | AI, defense, global, growth, innovation, Robotics, semiconductors, technology | AI continues to transform industries and drive market leadership, with infrastructure buildout continuing despite concerns about bubble-like excesses. The firm maintains meaningful exposure to AI enablers including semiconductors and digital advertising while staying disciplined on valuation and business quality. Semiconductor demand continues to outpace supply with visibility for AI-related spending extending into 2027. The portfolio maintains selective exposure focused on leading-edge logic chips and custom AI chip design services, with companies like TSMC and Broadcom positioned as key beneficiaries. Defense technology is entering a structural growth phase driven by rising geopolitical risk and convergence of military and commercial innovation. Focus areas include autonomous systems, space sensing, secure communications, and software that connects these pieces. Advances in AI compute power are pushing robotics forward with near-term opportunities in logistics and warehouse environments. The focus is on companies that make robots reliable, safe, and economically compelling rather than just headline-grabbing. Energy transition is blending with new power demand from data centers and AI infrastructure, creating a multiyear investment cycle across the entire power value chain. Opportunities emerging in companies that combine scale, speed, and technology to address grid complexity. Cyberattacks have become more frequent, costly, and sophisticated as more activity moves to the cloud and AI tools spread. Security is now a core operating requirement and foundation for trust with customers, regulators, and partners. Space is becoming part of everyday life with satellites supporting internet, defense, navigation, and climate monitoring. Costs are falling, tools are easier to use, and demand is rising, creating growing businesses with steady long-term revenue potential. | PLTR AVGO GOOGL MSFT NFLX NU SHOP KVYO CVNA TSM |

| 2025 Q4 | Jan 15, 2026 | ClearBridge Investments Small Cap Growth Strategy | 0.0% | 0.0% | BE, BETA, BHVN, DUOL, DYN, ELF, GKOS, IBP, INSM, LRN, NVS, PEN, PTGX, QLYS, RBC, SGRY, SSD, TREX, VRNS, WIX | active management, AI, Biotechnology, Capital markets, earnings, growth, small cap, Valuations | The manager expects 2026 could mark a period where productivity and monetization benefits of AI become more visible across industries. Several holdings are actively leveraging AI to improve efficiency, offer new products, or provide solutions to secure and manage critical data that AI utilizes. Biotech sector rebounded strongly behind positive clinical and commercial outcomes, healthy M&A activity, performance mean reversion and lower interest rates. The Russell 2000 Growth Biotech Index returned 28.1% in Q4, with the manager adding modestly to relative performance despite benchmark biotech constituents being up over 40% for the year. Capital markets appear to be accelerating with IPO activity improving after a multiyear lull and M&A volumes rebounding. This environment is historically favorable to the strategy, with recent transactions highlighting sophisticated buyers deploying capital at depressed valuations. Small cap earnings growth is forecasted to handily exceed large caps in 2026, with the third quarter marking the first time in over a decade that small caps exceeded large caps in earnings growth. The manager believes the asset class is poised for stronger performance with relative valuations still at attractive levels. | SIMP PTGX |

| 2025 Q4 | Jan 13, 2026 | Infuse Partners | -7.2% | 0.0% | DUOL, MELI, NU, SNWV, TMDX | E-Commerce, Education, Fintech, growth, Latin America, long-term, Medical Devices, technology | MercadoLibre continues to demonstrate exceptional execution with its e-commerce/payments flywheel spinning fast even at $25 billion revenue. The company has successfully outcompeted strong marketplaces like Amazon, Shopee, Temu and TikTokShop using vertical integration and fast delivery times. Management thinks genuinely long-term unlike most companies that only give lip service to long-term decision making. Nu Holdings is gradually becoming a super app with strong traction in Mexico after receiving full banking license, proving the model is replicable outside Brazil. The company's lean cost structure enables better rates, leading to more customers and economies of scale. Success has come despite Brazil's terrible macro backdrop over 15 years, with battle-tested lending algorithms positioned for expansion into more stable geographies. Sanuwave operates a razor and blades business model with the UltraMist device for treating diabetic foot ulcers. Despite a Q3 growth hiccup while building sales organization, growth should resume as there aren't many profitable medtech companies growing faster than 30%. TransMedics has revolutionized organ transplant process, owning 22 private jets and performing 30 organ transplants daily, with increasing density creating competitive advantages. Duolingo should be viewed as an engagement machine that happens to educate rather than just a language learning app. With almost 40% of monthly users logging in daily (compared to Snapchat's 50%), the company has built exceptional engagement muscle. As it broadens into math, music, chess and other subjects, retention should increase further, potentially becoming a must-have app for learning all sorts of things. | DUOL MELI TMDX NU |
