Why Applied Optoelectronics Stock Dived by Almost 14% on Monday

Applied Optoelectronics announced a new $600 million at-the-market (ATM) share offering, causing its stock to plunge nearly 14% on Monday. This is the company's second major capital raise in 2026, following a $250 million offering in February that was upsized to $500 million. While the offering itself isn't highly dilutive given the company's $9.1 billion market cap, investors are concerned about repeated equity offerings and the company's pattern of fully utilizing its allotments.
