Selling securities to the public, commonly called an Initial Public Offering (IPO), involves a structured process regulated by securities laws to ensure transparency and protect investors. Here's a basic overview of the procedure:

1. Preparation and Decision:
   The company decides to go public, usually to raise capital for expansion, reduce debt, or improve liquidity. It assesses its readiness by evaluating financial health, compliance, and market positioning.
2. Engaging Advisors:
   The company hires investment banks to act as underwriters. These professionals guide the IPO process, determine pricing, and help sell the securities.
3. Regulatory Compliance:
   The company prepares a detailed prospectus outlining its business model, financial performance, risks, and the purpose of the capital raised. This document is filed with the securities regulatory authority, such as the SEC in the U.S., for review and approval.
4. Roadshow:
   The company and underwriters conduct presentations to potential investors to generate interest. This phase helps gauge market demand and refine pricing.
5. Pricing and Offering:
   Based on investor feedback, the company finalizes the price of the securities. Once approved, the securities are offered to the public through stock exchanges.
6. Post-IPO Activities:
   After listing, the company complies with ongoing reporting requirements to maintain investor confidence and meet regulatory standards.
