Business Description

Corporate Information We were incorporated in the state of Delaware on January 3, 2011. Our wholly owned subsidiaries as of December 31, 2025 include HealthCare Pharmaceuticals Pty Ltd. (“HCP Australia”), Leap Securities Corp., Flame Biosciences LLC, and Leap Therapeutics, Inc. (“Leap”). Prior to October 2025, we devoted substantially all of our resources to development efforts related to biomarker-targeted antibody therapies designed to treat patients with cancer. Our clinical stage program is sirexatamab (DKN-01), a monoclonal antibody that inhibits Dickkopf-related protein 1, or DKK1, for the treatment of colorectal cancer patients. We also have a preclinical antibody program, FL-501, that is designed to treat cachexia-related indications. In October 2025, we announced a $58.88 million private placement, led by Winklevoss Capital, and the intent to initiate a digital asset treasury strategy. Immediately following the financing, we initiated a strategy to deploy a portion of our capital raised that is not required to provide working capital for our ongoing operations to accumulate digital assets, focused on Zcash. Zcash is a protocol and blockchain network of connected devices all over the world, working together to validate transactions and maintain the Zcash ledger. ZEC is the monetary unit, or coin, of Zcash. Zcash allows for transactional privacy, providing users with options for fully shielded transactions in which the sender, recipient, and amount are encrypted. On November 12, 2025, we changed our name from “Leap Therapeutics, Inc.” to “Cypherpunk Technologies Inc.” and changed our trading symbol from “LPTX” to “CYPH”. We were renamed to Cypherpunk to reflect the strategic focus on acquiring ZEC, participating in the development of Zcash, and the values of privacy and liberty. Our ongoing biotechnology research and development operations are conducted under a wholly-owned subsidiary named “Leap Therapeutics, Inc.”. We are a privacy technology company implementing a digital asset treasury strategy anchored by Zcash and, through our subsidiary Leap, are developing novel therapies for patients with cancer. Overview of Cypherpunk Cypherpunk is a privacy technology company. Our mission is to advance technologies that guarantee privacy for all humans on the internet. Our vision is a future where technology defends self-sovereignty and secures human freedom. We are not a typical digital asset treasury company. While we hold digital assets as part of our strategy, our core business is identifying, developing, investing in, and, where appropriate, acquiring or building privacy-enhancing technologies. Our initial and primary focus is the Zcash ecosystem, which we believe represents the most mature implementation of private digital money. Over time, we intend to assemble a portfolio of complementary privacy technologies that, together, are designed to secure privacy for individuals across the digital economy. We believe that privacy is a precondition for the meaningful exercise of individual freedoms, including freedom of speech, thought, and association. As digital systems expand and personal data generation accelerates, we believe demand for privacy-preserving infrastructure will grow and that the companies and protocols best positioned to provide it will capture significant long-term value. There are public companies focused on delivery, social networking, search, payments, and entertainment, among other sectors. To our knowledge, there is no publicly traded company whose core mission is the advancement of privacy technology. We intend to fill that gap. Our strategy is to combine disciplined capital allocation with active investment in privacy infrastructure, positioning the Company to benefit from what we believe is a structural increase in global demand for privacy-preserving technologies as digital surveillance capabilities expand and the volume of personal data generated continues to grow. 4 Table of Contents Privacy Strategy We are focused on identifying, developing, and investing in privacy-enhancing technologies that address the growing global demand for data protection, digital autonomy, and secure communications. We believe that privacy is an increasingly vital component of the digital economy and that technologies enabling responsible data protection, user control, and cryptographic security will play a critical role in future digital infrastructure.…
