“FTAI Aviation Ltd., Astera Labs, Inc., and Western Digital Corporation were among the top detractors from performance.”
Astera Labs - New positionClearbridge Investments Growth StrategySeptember 2026
“We also initiated and built a position in Astera Labs, which provides high-speed connectivity solutions that help enable data to move quickly and reliably between GPUs, CPUs, memory, storage and networking components within AI data centers.”
Astera Labs - New positionBaillie Gifford Global AlphaSeptember 2026
“That is where some of our semiconductor-equipment holdings come in. We have increased positions in DISCO, KOKUSAI, Lasertec and Besi. They operate in different niches, but the investment logic is similar: as chips become more complex and increasingly three-dimensional, the manufacturing processes required to produce them become more demanding, increasing the value of the specialist equipment these companies provide. And during the quarter, we bought Astera Labs, which helps data move efficiently between processors, memory and switches inside increasingly large AI systems.”
Astera Labs - September 2026
“Astera Labs (ALAB) is the leader in high-speed compute connectivity solutions. The stock earnings missed elevated expectations and investors questioned historically high valuations. Vertiv (VRT) is a global leader in power and thermal management solutions. VRT underperformed primarily due to missing revenue expectations, citing project execution and supply chain challenges. Intel (INTC) is one of the world’s largest semiconductor chip makers. Intel underperformed along with other semiconductor makers amid elevated valuations and investor concerns about AI spending durability. Casey’s General Stores (CASY) is a convenience store chain operator. The stock underperformed as same-store sales slowed notably and management did not raise guidance amid elevated expectations. Large Cap Growth Commentary: 3rd Quarter 2026 3 jagcap.com Portfolio Activity New Buys Full Sells Company Sector Palantir Information Technology Visa Financials Atlassian Information Technology Palantir (PLTR) is a leading data analytics and enterprise software company. We are re-establishing the position as US commercial revenue growth continues to accelerate as enterprises adopt the company’s industry-leading AI solutions. Additionally, the stock should benefit from improving sentiment surrounding Software as peak AI disruption fears fade. Visa (V) is the world’s leading payment processing network. We believe the stock is well positioned to outperform tied to healthy consumer demand and undemanding valuations. Atlassian (TEAM) is a leading provider of work collaboration software. Recent earnings showed growth acceleration across key metrics as Atlassian’s AI offerings are gaining traction. Additionally, the stock should benefit from improving sentiment surrounding Software as peak AI disruption fears fade. Company Sector Bloom Energy Industrials Intel Information Technology Walmart Consumer Staples XPO Industrials Astera Labs Information Technology Bloom Energy (BE) is an onsite power provider. We exited our position as relative strength continued to deteriorate and as the company could face challenges in scaling production given limitations on the supply of scandium. Intel (INTC) is one of the world’s leading semiconductor companies. We divested our position following significant outperformance as the upside potential is limited due to elevated expectations, in our view. Walmart (WMT) is the leading US retailer. We liquidated our position after the company delivered weaker-than- expected forward guidance in their most recent earnings report, which makes us less confident in the short/intermediate term outlook for the shares. XPO (XPO) is a leading less-than-truckload (LTL) trucking firm. We divested our position given deteriorating relative strength and mounting macro headwinds, including higher interest rate yields and elevated fuel costs. Astera Labs (ALAB) is the leader in high-speed compute connectivity solutions. We divested our position as relative strength continued to deteriorate after the company missed its quarterly earnings expectations.”
Astera Labs - September 2026
“Astera Labs designs semiconductor connectivity products that enable processors, memory, and networking equipment to communicate efficiently within artificial intelligence data centers.”
Astera Labs - June 2026
“Portfolio performance was also notably broad-based. While technology remained an important contributor, returns were generated across multiple sectors and investment themes. Taiwan Semiconductor, Applied Materials, Analog Devices, NVIDIA, Astera Labs and Seagate contributed meaningfully as part of our Compute Infrastructure theme.”
Astera Labs - June 2026
“Astera Labs (ALAB): A pure-play investment in the physical bottlenecks of AI infrastructure.”
Astera Labs - June 2026
“• Astera Labs designs high-speed semiconductor connectivity solutions for AI and cloud data centers. Its products, spanning PCIe, CXL, and Ethernet technologies, enable efficient data movement and signal integrity between GPUs, CPUs, and memory — effectively solving the bottleneck of how AI models communicate and operate within massive server environments at rack scale. We believe the company is positioned at the heart of the AI infrastructure buildout, given its expanding relationships with major hyperscale cloud providers and a rapidly growing product portfolio that addresses a large and growing market. Shares contributed positively to performance, supported by first- quarter results in which better-than-expected revenues were driven by hyperscale customers expanding their AI computing capacity, fueling strong demand for the company’s latest generation of connectivity products.”

Astera Labs - June 2026
“Astera Labs is a fabless provider of connectivity chips designed to address data, network and memory bandwidth bottlenecks in AI data centers. Quarterly results exceeded expectations, driven by continued strength in Peripheral Component Interconnect Express (PCIe) connectivity products and accelerating adoption of its Scorpio switch platform. The company also continues to invest in next-generation optical connectivity solutions, which we believe positions it well to benefit from longer term AI-driven infrastructure growth. We trimmed the position on valuation.”

“At the stock level. Progress has also been striking. Astera Labs is a good example.”
Astera Labs - March 2026
“During the quarter, shares detracted from performance despite a strong fiscal fourth-quarter earnings report that exceeded expectations on both revenue and earnings.”
Astera Labs - September 2025
“Astera Labs is a fabless provider of connectivity chips designed to address data, network and memory bandwidth bottlenecks in data centers. The company reported strong quarterly results and issued robust guidance, driven by rising demand for its AI-optimized products and sustained strength in data center spending. These results helped ease investor concerns about potential market share losses and order delays from a major customer. We remain confident in our investment thesis and believe Astera will continue to benefit from the expansion of data centers—driven by both cloud migration and increasing AI-related compute intensity. However, we exited our position during the quarter as its market capitalization exceeded the limits of our small-cap mandate.”

Astera Labs - MentionedPolen US SMID Cap GrowthDecember 2025
“Despite beating expectations on the top and bottom line, the stock sold off on the back of its earnings report given conservative Q3 and full-year guidance. We like Monday’s steady push up- market from SMB to enterprise customers, its expanding platform reach, and long-term vast market opportunities relative to its current size. Finally, not owning Astera Labs—up more than 100% during the quarter—represented another notable detractor to relative performance.”
