A company page draws on the SAFxCHANGE record: the agreement table (2013 to late 2023), the plants table (December 2023) and what the reader has found in the news since, marked unverified until checked. The categories follow the SAFxCHANGE value-chain map; they were assigned from the company's role in the deals and plants and from what is written about it, and a company can fill more than one. Names are matched by their words, so a company recorded under two very different names may show on two pages.
