Canadian Solar's (CSIQ) stock plummeted 5.59% during Wednesday's trading session following the company's announcement of a proposed offering of $200 million convertible senior notes due 2031. The offering includes an overallotment option of up to $30 million, with proceeds intended to fund U.S. manufacturing capacity and general corporate purposes.

Investors reacted negatively to the news, as convertible notes offerings often lead to dilution of existing shareholders' equity. The market's concern over the potential dilution and increased debt burden contributed to the sharp decline in the stock price. Analysts noted that such capital raises can weigh on short-term stock performance, especially when the company's valuation is already under scrutiny.
