Canadian Solar (CSIQ) saw its stock plummet by 9.45% during the intraday session on Thursday, following the company's announcement of a proposed offering of $200 million convertible senior notes due 2031.

The offering, which includes an overallotment option of up to $30 million, is intended to fund investments in U.S. manufacturing capacity and general corporate purposes. Investors reacted negatively due to concerns about potential dilution of existing shareholders' equity and the added debt burden, leading to the sharp decline in the stock price.
