Corning said surging optical-communications demand linked to AI data-center expansion propelled third-quarter sales and core earnings, prompting management to raise its fourth-quarter outlook and accelerate the company’s Springboard expansion plan.
Results Led by Optical Communications
Corning reported GAAP sales of $4.9 billion for the quarter ended September 30, 2026, up 18.0% year over year, and core sales of $5.1 billion, up 19.0%. Core earnings per share (EPS) rose 36.0% to $0.91, exceeding company guidance. The company presented GAAP and non-GAAP core measures side by side.
Optical Communications was the main growth driver, with sales of about $2.4 billion, up 44.0% year over year. Management attributed this to strong demand for optical-connectivity products tied to generative-AI data centers, identifying the segment as the chief source of momentum.
Guidance, Springboard Expansion, and Capacity Investment
Management forecast fourth-quarter core sales of $5.2 billion to $5.3 billion, about 19.0% higher year over year, and core EPS of $0.96 to $1.00, roughly 36.0% above the prior year. The outlook reflects continued strength in optical communications and the next phase of the Springboard expansion plan.
The company reported a core gross margin of 40.5%, up 150 basis points year over year; a core operating margin of 22.7%, up 310 basis points; and a core return on invested capital of 16.7%, up 330 basis points. Adjusted free cash flow was $661 million after investing more than $500 million in capacity to meet demand.
Management said third-quarter results supported accelerating the "20-30-40 Springboard" plan and that Corning had reached a sales run rate of about $20.3 billion, surpassing a prior $20.0 billion target for the end of 2026. This run rate underpins the company’s stepped-up expansion efforts focused on optical communications.
The company also reported that television units declined 4.0% and notebooks and handheld devices fell about 20.0% in the quarter. Related sales totaled $1.5 billion, down $54 million, or 3.0% year over year. Corning filed a Form 8-K on October 27, 2026, attaching the results release as Exhibit 99.
