I’m gonna go look it up now, but for those who follow behind me: can you explain what an S1 is?

Edit to add (emphasis mine):
SEC Form S-1 is the initial registration form for new securities required by the SEC for public companies that are based in the U.S. Any security that meets the criteria must have an S-1 filing before shares can be listed on a national exchange, such as the New York Stock Exchange. Companies typically file SEC Form S-1 when planning their initial public offering (IPO). SEC Form S-1 requires companies to explain the use of capital, outline their business model and competition, and provide a brief prospectus of the security, including pricing and any dilution of other securities.

SEC Form S-1 is also known as the registration statement under the Securities Act of 1933. Additionally, companies must disclose any significant business dealings with directors and outside counsel. Investors can view S-1 filings online to research new offerings before they are issued.
