Where this comes from

A company that wants to sell shares to the public in the United States files a registration statement with the SEC: Form S-1 for a US company, Form F-1 for a foreign one. It amends that statement as the figures and terms are filled in, usually adding the expected price range shortly before the offering. Once the offering is priced it files its final prospectus under Rule 424(b)(4). A company that decides not to go ahead can ask for the registration statement to be withdrawn on Form RW.

Every row on this page is one of those filings, linked to the filing itself. The facts are the company's own sentences, quoted from the filing named beside each one and never reworded; where no filing states a fact in a sentence that can be read exactly, this page leaves it out. A filing is the company's statement of its plans and its figures, not a verification of them, and nothing here is investment advice.
