• Earlier in January 2026, Canadian Solar Inc. secured a decisive win at the US Patent Trial and Appeal Board, which invalidated all Maxeon Solar Pte. Ltd. patent claims at issue and followed the company’s completion of a US$200,000,000 convertible senior unsecured notes offering due 2031.

What Is Canadian Solar's Investment Narrative?

To own Canadian Solar today, you have to believe in its ability to convert a large, low-margin solar and storage footprint into more durable profitability, while managing policy, financing and competitive pressures. The recent PTAB win against Maxeon removes an overhang around key US patents and reinforces the idea that its IP portfolio is an operational asset, not just a legal cost center, which could support confidence in its reshoring push and new product launches. Paired with the US$200,000,000 convertible notes, it also slightly shifts the near term story toward balance sheet flexibility and execution risk on new North American capacity, rather than headline legal risk. That said, the share price volatility and thin net margins mean the biggest questions still sit squarely around earnings quality and cash generation.

However, one key financial risk here is easier to miss at first glance. Canadian Solar's share price has been on the slide but might be dropping deeper into value territory. Find out whether it's a bargain at this price.
