Here are 1-3 brief analogies to describe Celestica (CLS):

• Celestica is like Foxconn, but specializing in manufacturing electronics for industrial, enterprise, and medical companies instead of primarily consumer gadgets.
• Celestica is like Magna International, but for electronic components and systems across diverse industries like aerospace, healthcare, and capital equipment.
• Celestica is like TSMC, but for assembling complete electronic products and systems for various brands, rather than just manufacturing semiconductor chips.

• Design & Engineering Services: Provides product design, development, prototyping, and testing services for electronic products across various industries.
• Electronics Manufacturing Services (EMS): Offers comprehensive manufacturing solutions including printed circuit board assembly (PCBA), system assembly, integration, and final product testing.
• Supply Chain Management: Manages global supply chains for customers, encompassing strategic sourcing, procurement, logistics, and inventory management.
• Aftermarket Services: Delivers post-manufacturing support such as product repair, refurbishment, warranty management, and recycling solutions.
• Joint Design & Manufacturing (JDM): Collaborates with customers on product design and then manufactures those products, often taking a more significant role in the initial product definition and architecture.

Celestica (symbol: CLS) primarily sells its services and solutions to other companies (B2B) rather than directly to individuals. As an electronics manufacturing services (EMS) provider, Celestica partners with Original Equipment Manufacturers (OEMs) and other companies across various industries to design, manufacture, and provide supply chain solutions for their electronic products.

Celestica generally does not publicly disclose the specific names of its major customer companies due to confidentiality agreements and competitive reasons. Therefore, it is not possible to list individual customer names and their symbols. However, based on their reported market segments, their customer base consists of companies operating in the following key industries:

• Aerospace & Defense: Companies producing avionics, satellite systems, defense electronics, and related equipment.
• Communications: Providers of telecommunications infrastructure, networking equipment, and other communication technologies.
• Enterprise: Manufacturers of servers, storage systems, enterprise computing solutions, and networking hardware.

The key risks to Celestica Inc. (CLS) are:

1. Customer Concentration: Celestica is highly dependent on a limited number of customers, particularly in its Connectivity & Cloud Solutions (CCS) segment. For instance, the top 10 customers represented 73% of total revenue in 2024, and in the second quarter of 2025, two customers alone accounted for 44% of sales. This significant reliance means that any reduction in orders or a shift by these key customers to in-house solutions could have a material adverse effect on Celestica's operating results, financial position, and cash flows.
2. Supply Chain Disruptions and Constraints: The company relies heavily on third-party suppliers for raw materials and components. Disruptions in the global supply chain, which can stem from geopolitical events, conflicts, or shortages (such as silicon), pose a significant risk. These disruptions can negatively impact Celestica's operations, lead to increased costs, and hinder its ability to meet customer demand and maintain its reputation.
3. Intense Competition and Margin Pressures: Celestica operates in a highly competitive Electronics Manufacturing Services (EMS) industry, facing rivals such as Foxconn, Flex, Jabil, and Sanmina. This competitive landscape exerts continuous pressure on pricing, profit margins, and the need for ongoing technological innovation. While Celestica's margins have been improving, they remain in the single digits on a GAAP basis, necessitating flawless execution to sustain profitability and compete effectively.

The accelerating trend among original equipment manufacturers (OEMs) towards establishing more regionalized and highly automated manufacturing facilities, either in-house or through partnerships with specialized, technology-first regional providers. This shift is driven by a desire for enhanced supply chain resilience, proximity to end markets, and the increasing viability of automation over low-cost labor. Such a paradigm shift could reduce the demand for large-scale, globally distributed electronics manufacturing services (EMS) companies like Celestica, as OEMs may choose to bypass traditional global EMS providers for certain product lines or regions, opting instead for agile, automated, and localized production.
