ORGANIZATION AND NATURE OF BUSINESS	ORGANIZATION AND NATURE OF BUSINESS Nature of Business and Operations Securitize, Inc. and its subsidiaries (“Securitize”, “Company”, and “our”), founded in 2017, is a Delaware corporation that operates a comprehensive platform for issuing, managing, and trading private market securities using blockchain technology. The Company provides a compliance-driven infrastructure that enables the tokenization of private securities, supporting functions such as dividends, distributions, share buy-backs, and investor servicing. The platform offers issuer services, including securities issuance and management, end-to-end document handling, and investor communications, as well as investor services, such as accreditation, wallet management, an investor dashboard, and token distribution. Additionally, the Company operates a registered broker-dealer and alternative trading system (ATS), facilitating compliant trading of digital asset securities. The Company is headquartered in Miami, Florida, with a global presence, maintaining offices in New York, Nevada, Spain, Israel, and Japan. On March 20, 2024, the Company announced the launch of the first tokenized fund in conjunction with the BlackRock USD Institutional Digital Liquidity Fund (BUIDL), which is issued on a public blockchain and managed by BlackRock Financial Management, Inc. On April 15, 2025, the Company completed the acquisition of MG Stover & Co. (“MG Stover”), a leading fund administrator for digital assets. The acquisition enhances the Company’s institutional fund administration services and positions Securitize as a leading provider in the U.S. digital asset market. The Company is subject to a number of risks, including limited operating history, dependence on key individuals, rapid technological changes, competition from larger companies, new entrants, the need for adequate financing to fund future operations, and the need for successful development and marketing of its products and services. Potential Business Combination with Cantor Equity Partners II, Inc.

The proposed transaction values the Company’s equity at approximately $1,250,000,000 and includes provisions for equity conversion and potential earn-out shares. The agreement also contemplates a concurrent private placement targeting $225,000,000 in gross proceeds and a minimum available cash condition of $100,000,000 at closing, which may be waived by the Company. Completion of the transaction is subject to customary conditions, including regulatory and shareholder approvals, and there is no assurance that the transaction will be consummated. The Business Combination will be accounted for as a reverse recapitalization, with no goodwill or other intangible assets recorded. Under this method of accounting, CEPT does not meet the Accounting Standards Codification (“ASC”) 805, Business Combinations (“ASC 805”) definition of a “business” and is treated as the “acquired” company for financial reporting purposes.
