Celestica Inc. CLS and Jabil Inc. JBL are two leading players in the electronics manufacturing services (EMS) industry. Celestica is one of the largest EMS companies in the world, primarily serving original equipment manufacturers, cloud-based and other service providers, and business enterprises across several industries. It offers a comprehensive range of manufacturing and supply-chain solutions that support various customer requirements, from low-volume, high-complexity custom products to high-volume commodity products.

On the other hand, Jabil is one of the largest global suppliers of EMS solutions. The company offers electronics design, production, product management and after-market services to customers in the aerospace, automotive, computing, consumer, defense, industrial, instrumentation, medical, networking, peripherals, storage and telecommunications industries. 

With domain-specific expertise in core areas, both Celestica and Jabil are strategically positioned in the EMS landscape and have the wherewithal to cater to the evolving demands of business enterprises. Let us delve a little deeper into the companies’ competitive dynamics to understand which of the two is relatively better placed in the industry.

The Case for Celestica

With more than 25 years of experience in manufacturing, backed by a simplified and optimized global network, Celestica is committed to delivering next-generation, cloud-optimized data storage and industry-leading networking solutions to help customers balance performance, power efficiency and space as technologies evolve. The company had benefited from the ongoing generative AI (artificial intelligence) boom, thanks to the solid demand trends for AI/ML (machine learning) compute and networking products from hyperscale customers.

By integrating next-generation networking products with silicon photonics packaging solutions, Celestica aims to optimize supply chain solutions to reduce time to market. The data center switches combined with optical transceivers have the potential to handle and sustain high volumes of both inbound and outbound network traffic and cater to the demand for data center bandwidth for supporting AI/ML and data analytics applications. These state-of-the-art products have translated into solid top-line growth in recent years.

However, the company remains plagued by margin woes. Celestica’s products are highly sophisticated and typically based on the latest technological innovations, which have historically led to high research and development costs. High operating expenses have contracted margins. Moreover, besides Jabil, Celestica faces stiff competition from industry giants like Foxconn, Flex and Sanmina Corporation SANM. The highly cyclical nature of the semiconductor industry further remains an overhang, particularly in the aftermath of reciprocal tariffs.

The Case for Jabil

With a presence across 100 locations in 30 countries, Jabil is likely to gain from secular growth drivers with strong margin and cash flow dynamics. Moreover, its unmatched end-market experience, technical and design capabilities, manufacturing know-how, supply chain insights and global product management expertise have put it in good stead. An extensive global footprint is further strengthened by a centralized procurement process, which, coupled with a single Enterprise Resource Planning system, aids customers with end-to-end supply chain visibility.

Jabil’s focus on end-market and product diversification is a key catalyst. The company’s target that “no product or product family should be greater than 5% operating income or cash flows in any fiscal year” is commendable. The diversification increases the reliability of the company’s earnings and revenues, thereby driving returns for investors in the long term. In addition, Jabil’s top-line growth is expected to benefit from strength in healthcare, cloud, retail and industrial. The company is likely to gain from the rapid adoption of 5G wireless and cloud computing. 

However, Jabil operates in a highly competitive environment, facing competition from both domestic and international electronic manufacturers, manufacturing service providers and designers like Sanmina. The tense geopolitical situation between the United States and China and the wars in Europe and the Middle East remain headwinds. Against the backdrop of this global uncertainty, low demand in some consumer-centric markets is negatively impacting its margins.
