Artisan Mid Cap Fund Matt Kamm, Jason White, Jim Hamel, Angela Wu, Jay Warner | “Astera Labs is a fabless provider of connectivity chips designed to address data, network and memory bandwidth bottlenecks in data centers. Modern GPUs and CPUs often cannot operate at full performance due to limitations in how they connect to memory and networks, and Astera's chips help remove these constraints to improve system efficiency. The company also enables communication across different types of chips, supporting the industry's shift toward heterogeneous computing. With continued cloud growth and rising AI demand driving rapid data center expansion, we believe Astera has a strong long-term growth opportunity. We took advantage of a recent pullback to start a GardenSM position. BSD Analysis: Astera Labs sits in a critical but underappreciated corner of AI infrastructure: high-speed connectivity between compute, memory, and accelerators. As AI systems scale, bottlenecks move away from raw compute and toward data movement — exactly where Astera plays. Its silicon and software solutions are tightly coupled, creating stickiness once designed in. Customer concentration is real, but that's the price of selling into hyperscale ecosystems. Growth is explosive today, but expectations are already aggressive. Execution and roadmap delivery matter more than TAM narratives from here. Margins reflect high-value IP rather than commodity silicon. This is not a “picks and shovels” cliché — it's a choke point. If AI keeps scaling, Astera stays relevant.” | BULL | Q4 2025 Jan 15, 2026 | View Pitch |
Alger Mid Cap Focus Fund Amy Zhang | “Astera Labs designs semiconductor solutions that help large-scale computing systems move data quickly and efficiently. Its products reduce bottlenecks that occur when data flow slows down inside servers or between chips. The company's Intelligent Connectivity Platform combines specialized hardware with its COSMOS software to create flexible, cost-effective solutions. These technologies are critical for connecting servers, GPUs, and AI accelerators. We believe Astera is well positioned in fast-growing markets like AI and cloud computing, supported by strong partnerships with leading technology providers. Shares gained after Q2 results beat estimates and revenue guidance was raised. Management expects next-gen X-series switches to become a major revenue contributor starting in 2026. BSD Analysis: Astera Labs is a pure-play on AI interconnect demand. With > 60% gross margins and rapid design-win momentum, the company should compound revenue > 35% annually as data-center buildouts expand. Trading near 12× FY26 sales like peer Mellanox at IPO, valuation is supported by secular tailwinds in PCIe and CXL standards. Catalysts include X-series launch and new OEM adoptions.” | BULL | Q3 2025 Oct 7, 2025 | View Pitch |
Spyglass Capital Management Portfolio Manager | “Astera Labs achieved outstanding revenue growth and cash flows while securing significant design wins for its next-generation fabric switches. However, because the stock price surged close to its estimated intrinsic value, the manager disciplinedly exited the holding. The manager maintains a positive fundamental outlook on the company and plans to monitor it for future entry points.” | BEAR | Q3 2025 Sep 30, 2025 | View Pitch |
Columbia Global Technology Growth Fund Columbia Management Investment Advisers, LLC | “Shares of leading AI connectivity specialist Astera Labs (ALAB) more than doubled during the quarter, driven by exceptional quarterly results and growing investor enthusiasm around the company's expanding role in next-generation AI data centers. The semiconductor company reported record revenue growth during the quarter, driven by insatiable demand for its new Scorpio line of products — which quickly became the fastest-growing product line in the company's history, after ramping up in production. Astera Labs has positioned itself as a mission-critical enabler for hyperscalers transitioning to AI computing, and its products play a key role in overcoming significant infrastructure challenges related to connectivity bottlenecks. BSD Analysis: Astera sits at the epicenter of AI infrastructure — PCIe, CXL, and high-speed connectivity for data centers that are getting choked by bandwidth limitations. Hyperscalers are throwing money at Astera because its connectivity silicon unlocks performance bottlenecks in GPU clusters. Revenue is exploding, design wins are piling up, and the company is scaling at Silicon Valley speed. This is a pure-play on data center interconnect growth, one of the strongest secular trends in tech. Astera is early, aggressive, and positioned directly in front of a multi-year AI capex wave.” | BULL | Q3 2025 Sep 30, 2025 | View Pitch |
Spyglass Capital Management Portfolio Manager | “Astera Labs beat consensus figures on top and bottom lines, with its stock gaining additional support as investors grew more confident in the persistent demand for AI infrastructure and custom ASICs. Despite trimming some shares after the rally, the manager believes the upcoming release of a new switch product offers a substantial growth runway.” | BULL | Q2 2025 Jun 30, 2025 | View Pitch |
