“Celestica has transitioned from its legacy roots as an IBM captive manufacturer to become a design and technology integration leader within the AI and cloud infrastructure space. The company's strategy is an acquisition model for the next two decades, acquiring various electronics and computer peripherals manufacturing and supply companies, highly tied to major OEMs like IBM, Avaya, and Lucent. At the beginning of the AI boom, the company found itself incredibly well positioned to provide specialized design, operational, and engineering services to large technology companies looking to build data centers or associated integrated rack systems. Within the CCS segment, the company serves enterprise AI companies and the hyperscalers, including Google, Meta, Dell, HPE, IBM, Juniper Networks, and Oracle Corporation, among others. Its customer base has significant near-term customer concentration among hyperscalers. In the first quarter of 2026, Celestica's top three customers individually accounted for 35%, 15%, and 15% of total revenue, representing a collective 65% concentration. To mitigate this risk and further entrench the company into hyperscalers, Celestica has integrated its operations into its customers' long-term capacity roadmaps. The company expanded its domestic manufacturing capacity in the United States, scheduled for completion in 2027, to support Google's U.S. production of complex TPU systems and secure multi-year program visibility. To be clear, Celestica is extremely tied to Google's TPU architecture success; any investor in Celestica should be bullish on Google's TPU systems. Celestica's business model combines global manufacturing capabilities, specialized engineering services, supply chain orchestration, and aftermarket lifecycle support, giving the company exposure to both data center design and construction as well as ongoing service and support. The core differentiator within the CCS segment is the Hardware Platform Solutions (HPS) portfolio (previously called Joint Design and Manufacturing (JDM)). HPS builds custom system-level rack integrations, which command higher margins than its traditional design process. Celestica is undergoing a structural margin expansion driven by its shift away from standard, low-margin contract manufacturing toward proprietary JDM services-led monetization. By co-developing proprietary, highly complex hardware with customers, the company compresses product launch cycles by approximately 30% per IR materials while capturing premium engineering margins. This HPS strategy allows Celestica to capture higher ASPs and secure customer stickiness through co-designed intellectual property. The financial success of this strategy is evident in the company's profitability progression with non-GAAP adjusted operating margins expanding from historical ranges of 4.0% to 5.0% to a record 8.0% in the first quarter of 2026, supporting further margin expansion. Overall, the management team is a group of long-tenured Celestica executives who have been with the company throughout its transition into this new AI landscape. Robert Mionis has served as President and Chief Executive Officer since August 2015 and assumed the role of Chair of the Board in 2026. Mionis brings a deep operational background, having served as President and CEO of StandardAero. He also held senior leadership positions at Honeywell, Honeywell Aerospace, and GE. Over his ten-year tenure at Celestica, Mionis has realigned the company's physical footprint with customer demand, reducing the company's manufacturing footprint by consolidating underutilized sites. He also holds over 1M shares in Celestica, almost 1% of the company. Chief Financial Officer Mandeep Chawla leads the company's capital allocation and financial risk management and has been with the company since 2010. Overall, the financial management of the company is conservative with a debt-to-EBITDA ratio of 0.6x. The company repaid over $530M of debt in the last year, which was a near term major use of excess cash. The company also has periodically executed share buybacks with excess cash over the last 5 years, reducing shares outstanding by 8% since 2020. Celestica is well-positioned for multi-year revenue and profitability growth, driven by secular tailwinds in AI data center expansion specifically leveraged to 1.6T networking and Co-packaged Optics (CPO), both of which are burgeoning trends in data center architecture. The primary driver of Celestica's long-term growth is the rapid expansion of AI applications and the associated data center infrastructure required. As hyperscalers scale their cloud networks to support complex large language models, demand for integrated AI/ML compute, high-density storage platforms, and complex rack systems are growing. The global data center networking market is projected to expand at a compound annual growth rate (CAGR) of 17.2% from 2025 to 2033. Celestica is a key hardware partner in this ecosystem, providing custom rack integrations, AI servers, and high-speed switches directly to hyperscaler clouds. The company's visibility is supported by non-cancelable, non-returnable long-term agreements, which provide superior revenue and capacity planning compared to previous technology cycles. The transition within data communication networks from 400G to 800G and next-generation 1.6T networking platforms represents a significant near-term catalyst for the company. Within its HPS portfolio, Celestica is ramping up production of its DS5000 800GbE switches, capturing higher average selling prices and superior margin profiles compared to legacy systems. Looking further ahead, the company has secured three separate 1.6 Terabit switching platform program awards with major hyperscaler customers, with initial production volumes scheduled to begin ramping in 2027. Additionally, Celestica has secured a strategic CPO Ethernet switch design win with a leading hyperscaler (likely Meta). At a current share price of approximately $340, Celestica trades at a forward EV/EBITDA multiple of 20.8x. Relative to other AI-datacenter-leveraged GARP companies (VRT, ANET, APH, FN, ALAB), this multiple is very cheap, especially when you consider the company is forecasted to grow 53% in 2026 and 40% in 2027. My assumption is that the margin improvements will continue into 2027 as CPO and 1.6T program ramps occur. This valuation gap suggests the market may still view Celestica as a traditional contract manufacturer rather than a custom hardware and systems integration partner. Analyst sentiment remains strongly positive, with all but one analyst rating the company a Strong Buy or Buy. Overall, I still believe the AI data center ramp has at least three years left in it, with very significant architecture changes driving huge demand across all hyperscalers in 2027 and 2028. These are the years that architecture in data centers begin to push the envelope of technology and physics, which requires specialty design, engineering, and manufacturing that Celestica specializes in. Celestica is the cheapest way to invest in growth in these AI trends; believe me I have looked at the entire space.” | BULL | Q2 2026 Jul 17, 2026 | View Pitch | |
ACATIS Investment Dr. Hendrik Leber | “Celestica is an electronic technology company that assumes tasks ranging from product development, prototyping and manufacturing (assembly, testing and integration) to logistics, returns and repairs as well as after-sales services on behalf of original equipment manufacturers. To this end, the company services growing industries in high-value segments such as cloud and AI infrastructure, smart energy, communication solutions, health and defense technology. Celestica has the potential to become more deeply involved in the development cycle of its clients, to strengthen customer loyalty and to become an increasingly important supplier for the infrastructure of digital trends. BSD Analysis: Celestica is currently navigating a period of technical consolidation in 2026, with the stock recently breaking through the floor of its long-term rising trend channel. This shift suggests a move toward a more horizontal development, as the stock trades between a support level of $250 and resistance at $343. Despite the slower rate of price increase, the firm remains a critical beneficiary of the ongoing shift toward advanced electronics manufacturing for AI data centers and communication infrastructure. Technical indicators like the RSI suggest some near-term bearish momentum, potentially offering an entry point for value investors as the firm's fundamental data remains healthy.

BlackRock Science And Technology Term Trust Tony Kim, Reid Menge | “The top contributor to portfolio performance was Celestica in Canada, which delivered a strong quarter on the back of continued robust demand from hyperscaler customers, particularly for 400G and 800G networking switches. Strong data center demand pushed operating margins to record levels and reinforced the company's leverage to secular growth in cloud infrastructure and AI networking. Management continues to execute well against these end markets, and the company remains well positioned to benefit as spending on high-speed networking equipment expands. BSD Analysis: Celestica is a high-growth electronics manufacturing services (EMS) leader whose stock is a leveraged bet on the multi-year AI data center buildout. The core thesis is driven by a massive, structural shift: the company's Connectivity & Cloud Solutions (CCS) segment is indispensable for hyperscalers and AI customers, driving surging demand. This momentum has fueled an approximate 260% twelve-month gain. The company raised its 2025 revenue guidance to about $12.2 billion and is focused on driving margin and EPS targets higher. Analysts emphasize its deep integration in AI infrastructure, highlighting 12-15 months plus of committed customer visibility. Celestica is a powerful, high-conviction exposure to the non-discretionary CapEx of the AI era.” | BULL | Q2 2025 Jun 30, 2025 | View Pitch |
