Organization and Description of Business | 1. Organization and Description of Business MDB Capital Holdings, LLC (“the Company” or “MDB”), a Delaware limited liability company, is a holding company that has three wholly-owned subsidiaries: MDB CG Management Company (“MDB Management”); Public Ventures, LLC, d/b/a MDB Capital (“Public Ventures”); and PatentVest, Inc. (“PatentVest”), and MDB Minnesota One (“M1”). MDB Management is principally an “administrative” entity whose purpose is to conduct, and wherever possible, to consolidate shared services/resources, for our US-based operations. Public Ventures is a U.S. registered broker-dealer under the Securities Exchange Act of 1934, and is a member of the Financial Industry Regulatory Authority (“FINRA”) and the Texas State Securities Board. Public Ventures operates on a fully disclosed basis with a nonrelated FINRA member firm, Interactive Brokers, LLC (“Interactive Brokers”), and is not required to maintain a clearing deposit. Interactive Brokers is the clearing firm and custodian of investments maintained by Public Ventures. PatentVest is a wholly-owned subsidiary that performs intellectual property validation services for Public Ventures’, due diligence functions on the intellectual property of partner and prospective partner companies, and creates an intellectual property roadmap for such partner companies. M1 is a majority owned subsidiary and was formed with the purpose of developing pharmaceuticals, based on patents and licensed technology from Mayo Foundation for Medical Education and Research (“Mayo”). The objective of the License Agreement is for Minnesota One to develop a small molecule senescence platform. On September 20, 2023, MDB completed an initial public offering, consisting of the sale of 1.67 million shares of Class A Common Shares at $12.00 per share, for gross proceeds of $20.0 million. Accordingly, the Company received total gross proceeds of $20.0 million from the sale of 1.67 million shares of Class A Common Shares, or $17.4 million net of $2.6 million of offering expenses. In conjunction with the IPO, the Company issued warrants to the placement agent to purchase 16.7 thousand shares of Class A Common Shares, exercisable upon issuance for a period of 5 years at $15.00 per share, for a cash consideration of $0.001/share. The placement agent’s warrants had a fair value of $65.4 thousand, as calculated pursuant to the Black-Scholes option-pricing model and accounted for as issuance costs that were accounted for as equity instruments and recorded against paid in capital. The inputs used to determine the fair value was Common Stock price of $12.00, option exercise price of $15.00, expected life in years of 2.45 years, with a contract life of 5 years, risk-free rate of 4.79%, expected annual volatility of 59.99%, and annual rate of dividends of $0. On July 1, 2024, the founding ownership of M1 had MDB owning 67% and Mayo owning 33% of the issued and outstanding common stock. M1 was formed with the purpose of developing pharmaceuticals, based on patents and licensed technology from Mayo. After the initial formation of M1 and finalization and entry into a license agreement between Mayo and M1, MDB entered into a Term Equity Purchase Agreement (“Purchase Agreement”) to provide capital for operations of M1 in exchange for the issuance of shares of common stock of M1 to MDB. The objective of the License Agreement is for M1 to develop a small molecule senescence platform. Under the terms of the License Agreement M1 has paid an up-front license fee to Mayo of One Hundred Fifty Thousand Dollars ($150 thousand). To maintain its rights under the License Agreement, M1 is subject to achieving certain developmental and funding milestones within designated time periods and to paying Mayo royalties on net sales of licensed products. Under the terms of the Purchase Agreement, MDB may invest up to $5.0 million over a five-year period into M1 in amounts and increments tied to its business operating requirements. In an ancillary agreement to the license agreement, Mayo has the right of participation in future financings of M1.
