Jabil beats Corning on AI chip-demand play—cheaper valuation, faster growth

Jabil Inc. and Corning Incorporated occupy complementary positions in the AI data-center supply chain, yet their business models and growth trajectories diverge in ways that matter for investors. Jabil is one of the largest global suppliers of electronics manufacturing services (EMS), offering not only contract manufacturing but also networking, photonics, power and cooling solutions tailored for AI infrastructure. The company operates across 100 locations in 30 countries, giving it geographic diversification and the operational flexibility to serve customers across multiple regions. Management is actively improving working capital and integrating AI and ML capabilities into its internal processes—a reflection of the company's ambition to enhance efficiency as demand for AI infrastructure accelerates. Jabil's top line is expected to benefit from strength in AI data-center infrastructure, capital equipment, and warehouse automation, while long-term tailwinds include the adoption of 5G wireless and cloud computing.

Corning, by contrast, has narrowed its strategic focus around five Market-Access Platforms: Mobile Consumer Electronics, Optical Communications, Automotive, Life Sciences, and Display. Its primary contribution to AI infrastructure is optical fiber and connectivity technologies essential for high-speed AI data-center networks. Beyond this, Corning is known for Gorilla Glass and manufactures specialty materials including glass, glass ceramics, fluoride crystals, glass substrates for LCD and PC displays, automotive glass, and laboratory equipment. The company has reorganized its operating structure to align business teams around these platforms, creating opportunities for asset and capability reuse across market ecosystems. Corning has demonstrated a leadership position in each of its five markets, and this reorganization has increased efficiency.

From a growth perspective, both companies show solid momentum for 2026. Jabil's Zacks Consensus Estimate projects sales growth of 17.3% and EPS growth of 30.7% on a year-over-year basis, with EPS estimates up 3.6% over the past 60 days. Corning's estimate stands at 15.8% sales growth and 29.8% EPS growth, with EPS estimates increased 2.5% over the past 60 days. The gap between them is narrow—JBL leads in both metrics by roughly 1.5 percentage points for sales and 0.9 percentage points for EPS.

Valuation tells a starkly different story. Jabil trades at 20.56 times forward earnings, while Corning trades at 40.61 times. Over the past year, Corning has gained 140%, compared with Jabil's 46.2%, indicating that the market has substantially repriced Corning's growth prospects. However, both companies face material risks. Jabil operates in a highly competitive landscape alongside domestic and international rivals like Sanmina, and geopolitical tensions between the United States and China, along with conflicts in Europe and the Middle East, create supply-chain and margin headwinds. Consumer-centric market weakness is also weighing on profitability. Corning's exposure is more concentrated: the Display and Optical segments account for more than half of total revenues, with Display dependent on consumer spending on LCD TVs and mobile PCs. Corning also faces tariff risk in China amid U.S.-China trade friction. Despite these risks, both companies are well-positioned for the sustained AI infrastructure demand expected in 2026. Jabil carries a Zacks Rank #1 (Strong Buy), while Corning holds a Zacks Rank #3 (Hold), suggesting that analysts view Jabil as the more attractive entry point for new capital.
