Corning Falls 16% After Q2 Earnings, Optical Stocks Drop
Corning shares plunged about 16% after the company reported second-quarter results that beat EPS and revenue estimates but issued revenue guidance below Street consensus. Corning reported EPS of $0.78 (vs. $0.76 estimate) and revenue of $4.74 billion (vs. $4.61 billion estimate), while forecasting core revenue growth of about 16% with a range of $4.9 billion to $5.0 billion — below FactSet consensus of $5.0 billion. The sell-off in Corning weighed on other optical-component stocks including Marvell, Lumentum, AXT and Coherent, which fell double digits. The story notes Corning’s growing role in AI data center networking and a recent multi-year deal with Amazon to connect data centers.
Public earnings and forward revenue guidance from a major supplier tied to AI data center infrastructure led to a large stock move and pressured related optical-component stocks; this signals demand/capex trends relevant to technology supply chains.

Corning Secures Multibillion Optical-Fiber Deal with Amazon
Corning announced a major multibillion-dollar supply agreement with Amazon for optical fiber to support Amazon’s growing data-center and AI infrastructure. The deal will enable Corning to expand production and is expected to create about 1,000 jobs at its North Carolina manufacturing facilities. Corning’s stock jumped on the news, and the company highlighted recent strength in its optical communications segment after other large supply partnerships with hyperscalers such as Meta and a recent supply agreement plus $500 million investment from Nvidia. Corning CEO Wendell Weeks has said additional large agreements with hyperscalers are in place, though the company allows customers to disclose details on their own timelines.
Cisco stock drops despite earnings beat
Cisco reported fiscal Q4 results that beat expectations—adjusted EPS $1.22 vs $1.17 expected and revenue $17.25 billion (about an 18% year‑over‑year increase) vs $16.82 billion expected—and guided current‑quarter revenue to $18.0–$18.2 billion versus the $16.8 billion LSEG consensus. Hyperscalers placed roughly $4 billion of infrastructure orders in the quarter, bringing fiscal‑year hyperscaler orders to $9.3 billion; Cisco expects hyperscaler‑related revenue to rise to about $7.5 billion in fiscal 2027. Net income rose 51% year‑over‑year to $3.9 billion (97 cents a share). Despite the beat and above‑consensus guidance, shares fell about 9% on Aug. 13, 2026. Some analysts (Piper Sandler) called the guidance conservative while KeyBanc remained bullish; management described the period as a record quarter but urged prudence entering the new fiscal year.
