BioSig Technologies, Inc. and Streamex Exchange Corporation said ealier today they have reached a definitive agreement with a leading institutional investor for up to $1.1 billion in growth financing.
The deal includes $100 million in senior secured convertible debentures and a $1 billion equity line of credit.
The move aims to make the merged company one of Nasdaq’s largest public holders of gold bullion and to accelerate its plan to bring the $142 trillion commodities market on-chain through real-world asset tokenisation.
Financing Details
Under the agreement, BioSig and Streamex will sell $100 million in senior secured convertible debentures that mature 24 months after issuance. The notes carry an interest rate of 4 % per year, which will rise to 18 % if the company fails to meet its obligations until the default is cured.
The debentures will be issued at 96 % of their face value. They can convert into common stock, and the company will grant a first‑priority lien on certain assets as security.
In addition, the companies have an equity line of credit allowing them to sell up to $1 billion of common shares over 36 months at their option. BioSig and Streamex will file a registration statement with the SEC to cover the shares issued on conversion or sale.
The initial closing of $75 million in debentures and the equity line of credit is expected on or about October 7, 2025, subject to shareholder approvals required by Nasdaq rules and other closing conditions.
The remaining $25 million in debentures will close once the resale registration statement is effective and other conditions are met.
Strategic Vision
The financing supports the companies’ shared goal of reshaping global finance by tokenising real-world assets. BioSig CEO and Streamex co‑founder Henry McPhie said combining physical gold with blockchain innovation will build a firm backed by a trusted store of value.
He added that the platform will unlock liquidity, transparency and wider access across the commodities market.
Streamex co‑founder and BioSig chairman Morgan Lekstrom said on‑chain integration of gold and other commodities offers a new value proposition for token holders and marks a key innovation in finance.

Gold Treasury Model
BioSig and Streamex plan to hold large amounts of gold bullion in allocated vaults with a top‑tier bullion bank. They intend to denominate most of their balance sheet in vaulted physical gold rather than fiat currency.
The companies believe that pairing gold holdings with their Solana blockchain tokenisation will create a recurring revenue model and generate strong returns.
Their integrated platform aims to issue a range of gold‑backed tokens that offer low‑cost access to gold investments and support financing structures with the potential for returns that beat plain bullion holdings.
Leadership and Advisors
The executive team is led by CEO Henry McPhie and Chief Investment Officer Mitch Williams. Their backgrounds include roles at OppenheimerFunds, Credit Suisse, Wafra Inc., Laconic, Rio Tinto, NexMetals and Freeport‑McMoRan.
The board also includes strategic advisors such as mining financier Frank Giustra, who called gold the ultimate hedge against economic and geopolitical risks, and entrepreneur Sean Roosen, who said the company represents the next step in mining finance by linking projects to new investors.
This $1.1 billion financing positions BioSig and Streamex to secure a leading role in gold treasury and real-world asset tokenisation. By blending physical bullion with blockchain, the merged firm aims to offer investors new ways to access and invest in commodities.
