Documents the company has filed with the SEC for this offering.
What is an IPO?
An initial public offering is the first time a private company sells shares to the public. The company files a registration statement (an S-1) with the SEC, sets a target price range with its underwriters, and shares begin trading on an exchange on the pricing date.
Price range
A non-binding range from the prospectus. Underwriters set the final price the night before trading opens — it can land above, below, or inside the range based on order book demand. The first trade on the exchange (the open) often differs from this price.
Shares offered
The number of shares the company plans to sell at the IPO. This excludes the over-allotment option (the 'greenshoe', typically up to 15% extra) that underwriters can exercise if demand is strong.
Estimated raise
A rough estimate of how much the company will raise — midpoint price multiplied by shares offered. Actual gross proceeds depend on final pricing; net proceeds are lower after underwriting fees and expenses.
SIC industry code
The Standard Industrial Classification code (1040) is the SEC's bucket for the company's primary line of business — here: Gold and Silver Ores. It's used for peer comparisons and regulatory filings.
State of incorporation
Where the company is legally chartered (here: DE). It governs corporate law — shareholder rights, board duties, takeover defenses — and is independent of where the business actually operates. Most US issuers incorporate in Delaware.
Lock-up periods. Insiders, early investors, and employees usually agree not to sell for 90–180 days after the IPO. Once the lock-up expires, additional supply can hit the market.
First-day pop or drop. The opening trade on the exchange is set by demand, not the underwriters' price. It can be substantially above or below the IPO price; subsequent days are often volatile as price discovery continues.
Limited trading history. A newly-listed company has no public-market price history, no analyst consensus, and limited float — many of the technical and statistical signals used elsewhere on this site only become meaningful after several weeks of trading.
Read the S-1. The prospectus is the only legally binding source for risk factors, use of proceeds, financials, and ownership. Anything you read elsewhere — including this page — is a summary at best.
