GET DAILY SIGNALSCLS vs FN: Celestica and Fabrinet Positions in the AI Infrastructure Build
Key Takeaways
- CLS (Celestica) and FN (Fabrinet) are both manufacturing partners to the AI (artificial intelligence) and data center supply chain, but they occupy different roles within it.
- Celestica is a larger, diversified electronics manufacturing services (EMS) player focused on hyperscaler compute and networking hardware; Fabrinet is a smaller precision optical packaging specialist.
- Both companies are growing rapidly, with Celestica posting roughly 62% year-over-year revenue growth in its most recent quarter and Fabrinet growing revenue 36% for its latest fiscal year.
- Celestica has shown stronger recent share-price momentum, while Fabrinet delivered a large earnings beat but a more mixed market reaction.
- Customer concentration is a shared risk: a handful of large hyperscaler and networking customers account for a significant share of revenue at both companies.
- Their relative positioning largely hinges on whether investors favor broader AI-compute exposure (Celestica) or precision optical packaging (Fabrinet).
Introduction
Celestica and Fabrinet sit at the center of one of the market's most closely watched themes: the build-out of AI infrastructure. Although both are contract manufacturers serving the same broad technology ecosystem, their business models, growth drivers, and risk profiles differ meaningfully. Celestica is a diversified electronics manufacturer supplying compute, storage, and networking hardware to large cloud and enterprise customers. Fabrinet specializes in advanced optical packaging and precision manufacturing for optical communications, data center interconnect, and other complex devices. For traders and investors weighing relative performance and market positioning, this stock comparison examines how each company has performed in recent weeks and what is shaping sentiment in the current environment.
Celestica Overview and Recent Performance
CLS, Celestica, is a global design, engineering, and manufacturing partner serving the data center, communications, aerospace and defense, industrial, and healthcare markets. Its most important near-term growth engine is the Connectivity & Cloud Solutions (CCS) segment, which supplies Hardware Platform Solutions (HPS) — including compute, storage, and networking systems — to hyperscaler and enterprise customers. Recent financial results underscore strong demand. In its latest reported quarter, Celestica grew revenue roughly 62% year over year to about $4.7 billion, led by an 84% increase in CCS revenue, and raised its full-year 2026 outlook to approximately $20.5 billion to $21 billion in revenue. Management has pointed to accelerating hyperscaler AI and cloud demand, scaling 800G switching, and the ramp of 1.6T (terabit) programs as key catalysts. Celestica has also disclosed collaborations tied to AI compute platforms, including advanced AI racks developed with Broadcom to support OpenAI's custom accelerator roadmap and a design-and-manufacturing role in AMD's Helios platform. A multibillion-dollar equity raise has supported expanded manufacturing capacity. This momentum has contributed to strong share-price gains in recent weeks, though customer concentration — three customers accounted for 36%, 15%, and 12% of revenue in one recent quarter — remains a central risk. I also checked this using Tickeron’s AI Screener to see how the stock compares to others in the industry.
Fabrinet Overview and Recent Performance
FN, Fabrinet, is a leading provider of advanced optical packaging and precision optical, electro-mechanical, and electronic manufacturing services. Headquartered in Thailand, it serves original equipment manufacturers of optical communication components and modules, automotive components, medical devices, and industrial lasers. Its core strength is high-precision, high-complexity manufacturing, increasingly anchored by data center demand. Fabrinet's latest fiscal quarter showed record results: revenue rose about 45% year over year to $1.32 billion, and non-GAAP (non-GAAP, or adjusted, measures exclude certain items) earnings per share (EPS) increased roughly 55% to $4.10, beating analyst estimates. For the full fiscal year, revenue grew 36% to about $4.6 billion. Data center revenue became the company's largest category at 51% of sales, with data center interconnect (DCI) exceeding a $1 billion annualized run rate. Operating margin reached a three-year high of 10.9%. The company is expanding capacity aggressively, including a major new Thailand facility expected to add billions of dollars in annual revenue capacity. Notably, despite the strong results, Fabrinet's shares fell in after-hours trading following its latest earnings report, reflecting elevated expectations and concentration risk among major customers such as Cisco, Nvidia, Nokia, and Amazon.
Head-to-Head Comparison
The clearest contrast between these two stocks is their position in the AI value chain. Celestica supplies complete hardware platforms — racks, servers, storage, and switches — giving it broad, direct exposure to hyperscaler compute spending. Fabrinet focuses on precision optical packaging and interconnects, a more specialized layer of the same build-out. This translates into different scale and growth profiles: Celestica is targeting a roughly $20 billion-plus annual revenue run rate, while Fabrinet is exiting its fiscal year at a far smaller base of about $5 billion. Recent momentum has favored Celestica. The stock has posted strong gains in recent weeks on the back of raised guidance and new program wins, whereas Fabrinet delivered a substantial earnings beat but experienced a more muted market response — a sign that expectations were already elevated. Risk factors also differ in emphasis. Both companies face customer concentration, but Celestica's reliance on a few hyperscalers and its exposure to tariff and trade dynamics are notable, while Fabrinet's gross margin of roughly 12% reflects the lower-margin, high-volume nature of its manufacturing model. Sector exposure is another distinction: Celestica is more diversified across cloud, aerospace, industrial, and healthcare, while Fabrinet is more concentrated in optical communications and data center interconnect.
Tickeron AI Verdict
Based on observable factors, Tickeron's AI would likely tilt toward CLS in the current environment. Celestica combines stronger recent trend consistency, upward revisions to its full-year outlook, and a broader set of AI-compute catalysts, including the ramp of 1.6T programs and new hyperscaler collaborations. Fabrinet's fundamentals remain robust, with record revenue and expanding margins, but its post-earnings price reaction suggests a more demanding setup and less decisive short-term momentum. That said, positioning is inherently probabilistic rather than definitive, and each stock carries meaningful concentration and execution risks. Investors focused on precision optical packaging may still find FN compelling, even as the current trend evidence appears marginally more favorable for Celestica.
