This is an initial public offering of shares of common stock by Carlsmed, Inc. We are offering 6,700,000 shares of common stock, par value $0.00001 per share (“common stock”). The initial public offering price is $15.00 per share.
Our common stock has been approved for listing on The Nasdaq Global Select Market under the symbol “CARL.”
Upon completion of this offering, our executive officers, directors, owners of 5% or more of our capital stock and their respective affiliates will own, in the aggregate, approximately 57.1% of our common stock (assuming no exercise of the underwriters’ option to purchase additional shares and no purchase of shares in this offering by anyone in this group). These stockholders will be able to exercise significant control over matters requiring stockholder approval, including the election of directors, amendment of our organizational documents, and approval of any merger, sale of assets, and other major corporate transaction.
We are an “emerging growth company” and a “smaller reporting company” under the U.S. federal securities laws, and, as such, we have elected to comply with certain reduced public company reporting requirements for this prospectus and may elect to do so for future filings.
