On July 31, Corning rose 3.16% in after-hours trading, trading at $139.5/share, with turnover of $279 million, extending a rebound following a cumulative decline of over 20% across two prior trading sessions.

On the news front, multiple institutions including UBS and Oppenheimer maintained buy ratings despite cutting price targets, calling the prior selloff overdone. UBS lowered its target to $196 from $228, while Oppenheimer trimmed to $200 from $230. Both firms emphasized that the long-term growth thesis around AI data center fiber optic demand remains intact, and that the current valuation has become more attractive after the sharp correction. UBS noted that while Corning's strategy of locking in more long-term offtake contracts may limit near-term margin expansion, it provides greater stability in earnings growth.

Corning had previously reported Q2 core sales of $4.74 billion, up 17% year-over-year, with optical communications revenue surging 32%. However, its Q3 guidance midpoint of $4.95 billion fell slightly below the consensus estimate of $5.0 billion, triggering massive profit-taking given the stock's near-100% YTD gain and approximately 44x PE valuation at the time.
