Corning plunges 12% on $2B equity offering, dragging AI optics peers down sharply.

Corning's shares dropped 12% after announcing a $2 billion at-the-market equity offering, causing a selloff in the AI optical sector. This move introduces uncertainty as Corning can sell shares at any time and price, diluting existing shareholders. Peers like Coherent, Lumentum, and Fabrinet also fell due to sector-wide concerns and recent comments urging slower AI spending. Investors should watch Corning's future disclosures on share sales and the broader AI investment debate for further market impact.
