Jabil vs. Corning: Which AI Infrastructure Stock is the Better Buy?

Jabil Inc. JBL and Corning Incorporated GLW are prominent beneficiaries of the AI data-center buildout. Jabil is one of the largest global suppliers of electronics manufacturing services (EMS) solutions. It also offers networking, photonics, power and cooling solutions for AI infrastructure.

Corning supplies optical fiber and connectivity technologies essential for high-speed AI data-center networks. In addition to being a pioneer in Gorilla Glass technology, the company manufactures specialty materials, including various formulations for glass, glass ceramics and fluoride crystals for specific industrial and commercial applications. It also manufactures optical fibers, glass substrates for LCD and PC displays, automotive glass solutions and various laboratory equipment.

With domain-specific expertise in core areas, both Jabil and Corning are strategically positioned in the tech-adjacent manufacturing landscape and have the means to cater to the evolving demands of business enterprises and AI/ML technology. 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 JBL

With a presence across 100 locations in 30 countries, Jabil is likely to gain from secular growth drivers with strong margins 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.

Management’s focus on improving working capital management and integrating sophisticated AI and ML capabilities to enhance the efficiency of its internal processes is a major tailwind. Jabil’s top line is expected to benefit from strength in AI data center infrastructure, capital equipment and warehouse automation markets. The company is likely to gain from the rapid adoption of 5G wireless and cloud computing in the long run. It is benefiting from solid demand in key end markets, together with excellent operational execution and skillful management of supply-chain dynamics. 

However, Jabil operates in a highly competitive environment, facing competition from both domestic and international electronic manufacturers, manufacturing service providers and designers like Sanmina Corporation SANM. 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.

The Case for GLW

Corning is benefiting from improved demand and the commercialization of its innovations. Its capabilities are becoming increasingly vital to diverse industries. The fiber optic solutions business is likely to be the key growth driver for GLW, aided by the increasing use of mobile devices that require efficient data transfer and networking systems. Supporting this trend is the proliferation of clouds, resulting in increased storage and even virtual computing.

Since both consumers and enterprises are using networks more extensively, and the generated data is increasingly being used to train AI models, there is a solid demand for Corning’s innovative optical connectivity products for generative AI applications.

GLW’s operating structure has been reorganized to align executive management and business teams around five Market-Access Platforms to unlock opportunities for valuable synergies. These are Mobile Consumer Electronics, Optical Communications, Automotive, Life Sciences and Display. Corning has a leadership position in each of these markets, which, along with focused marketing efforts, has proved conducive to growth. In addition, the reorganization has increased efficiency by creating the opportunity to reuse assets and capabilities developed for customers in one market ecosystem to serve customers in another.

However, end market diversification is limited within the Display and Optical segments, which account for more than half of total revenues. Since the Display Technologies and Specialty Materials segments are primarily dependent on consumer spending, particularly on LCD TVs and mobile PCs, this narrows down the market. Building a significant market position in China amid a bitter U.S.-China trade relationship with heightened risk of the imposition of tariffs can adversely impact its operations.
