S-1 filings, read

A company going public in the US files a prospectus with the SEC: the S-1 (F-1 for a foreign company), then amendments, then the final one with the price. Each page here reads one of them page by page, in a fixed order: is revenue really growing, does it fund its own growth, is the debt sane, does the profit show up as cash, and only then the price. Every figure carries the page it was printed on.

Left out: 14 filings by companies already public, which register shares for resale rather than list for the first time, and 6 blank-check companies (SPACs) and funds.
