Aristotle Small Cap Equity Fund Jack McPherson and Dave Adams | “MACOM Technology Solutions is a designer and manufacturer of high-performance semiconductor products. The stock benefitted from strong earnings results and forward guidance featuring co” | BULL | Q2 2026 Aug 10, 2026 | View Pitch |
Artisan Partners Small Cap Fund Jay Warner | “MACOM designs and manufactures high-performance semiconductors. The company has benefited from a favorable profit cycle across its data center, industrial, defense and telecom end markets, supported by strength in optical networking, satellite communications and defense systems. Shares rose after the company delivered better-than-expected revenue and issued stronger-than-expected guidance, driven by strength in data center hardware, industrial and defense demand. We harvested some capital as the company's market capitalization moved beyond the parameters of our small-cap strategy, while maintaining our conviction in the franchise and its profit cycle. Although valuation expectations have increased, we believe they remain reasonable from a multiyear perspective.” | NEUTRAL | Q2 2026 Jul 21, 2026 | View Pitch |
Artisan Global Discovery Jason White | “MACOM designs and manufactures high-performance semiconductors. Shares rose after the company delivered in-line results and issued a stronger-than-expected Q1 outlook. Its results included sequential gross margin improvement and one of its strongest booking quarters in years, as demand remained robust across key end markets, including data infrastructure and satellite communications. The company continues to execute on its strategy of expanding margins through differentiated compound semiconductor solutions and product cycles. We trimmed the position in line with our valuation discipline. BSD Analysis: MACOM is a key beneficiary of the high-speed networking and AI infrastructure boom, providing high-performance semiconductor solutions for data centers and telecommunications. The company's 2026 outlook is supported by surging revenue growth, driven by its industry-leading optical and radio frequency (RF) components. Its "fab-rite" manufacturing model allows it to maintain a flexible cost structure and achieve superior gross margins compared to traditional integrated manufacturers. For 2026, the investment thesis centers on the massive rollout of 800G and 1.6T networking products, which are essential for connecting the next generation of AI clusters. Institutional interest is rising as the company consistently beats earnings expectations and expands its design wins among top-tier cloud providers. With a strong balance sheet and a focus on long-lifecycle products, MACOM offers a high-quality way to play the expansion of global digital connectivity.” | BULL | Q4 2025 Jan 27, 2026 | View Pitch |
Artisan Partners Small Cap Fund Jay Warner | “MACOM designs and manufactures high-performance semiconductors. Last quarter, the stock was among our bottom three contributors, but we believed pressures on the profit cycle were temporary and added capital to the position. Those issues proved to be transitory, and the company continues to execute on its strategy of expanding margins through differentiated compound semiconductor solutions and product cycles. We have since trimmed the position in line with our valuation discipline. BSD Analysis: MACOM supplies high-performance analog semiconductors into defense, aerospace, and data infrastructure where reliability is non-negotiable. Products are deeply engineered and qualified, making switching slow and costly. Demand is lumpy due to program timing, not consumer cycles. Investors treat MACOM like a generic chip name and miss its specialty nature. Margins reflect customization and IP depth. Defense exposure adds durability through cycles. When programs ramp, earnings leverage is meaningful. This is niche silicon with real barriers. Complexity quietly pays.” | BULL | Q4 2025 Jan 21, 2026 | View Pitch |
Artisan Partners Small Cap Fund Jay Warner | “MACOM designs and manufactures high-performance semiconductors. The company delivered better-than-expected quarterly results. However, it was required to assume operational control of the fabrication facility acquired from Wolfspeed approximately six months ahead of schedule, following Wolfspeed's bankruptcy filing. This accelerated transition has temporarily weighed on MACOM's near-term margin outlook, though we believe the impact will be short-lived. We took advantage of the resulting share price weakness to increase our position. BSD Analysis: The thesis is that temporary fab transition headwinds mask solid demand and execution. With strong design-in pipeline across optical/defense and improving mix, margins should recover; pullback offered an attractive add.” | BEAR | Q3 2025 Oct 20, 2025 | View Pitch |
Artisan Partners Small Cap Fund Jay Warner | “MACOM designs and manufactures high-performance semiconductors. The company has been taking steps to accelerate top-line growth and expand margins by addressing smaller, long-duration product cycle markets in which it can provide a differentiated offering, especially in compound semis (those made from two or more elements). Demand remains strong across MACOM's key end markets, including US and European defense, data center and even telecom—spanning both long-haul and satellite segments. Moreover, MACOM's above-average semiconductor production footprint within the US likely reduces its exposure to potential industrywide disruptions related to any potential tariff risks. BSD Analysis: MACOM benefits from accelerating demand across defense, data-center and telecom markets, positioning it as a differentiated supplier in compound semiconductors. Its U.S.-based footprint mitigates geopolitical and tariff risks, supporting more stable margins. With increasing exposure to long-cycle markets, revenue visibility is improving, and MACOM trades at a reasonable EV/EBITDA relative to secular semiconductor peers. Continued design wins and margin expansion are likely catalysts. Key risks include supply-chain timing and sector cyclicality.” | BULL | Q2 2025 Jul 22, 2025 | View Pitch |
