Bitcoin Miner TeraWulf Announces $400M Private Notes – Data Center Push, $60M Upsize Option

Bitcoin miner TeraWulf Inc. announced that it intends to raise $400 million through a private offering of convertible senior notes due 2031, according to a press release published on August 18.

The company said the offering will be made to qualified institutional buyers under Rule 144A of the Securities Act of 1933. Initial purchasers will also have the option to buy up to an additional $60 million of the notes within 13 days of issuance.

TeraWulf Explains Use of Proceeds

TeraWulf said proceeds from the sale will be used in part to cover costs of capped call transactions, with the remainder directed toward expanding its data centers and other corporate purposes. The company described the notes as senior unsecured obligations carrying semi-annual interest payments beginning March 1, 2026, and maturing on September 1, 2031, unless repurchased, redeemed, or converted earlier.

The notes will be convertible into cash, shares of common stock, or a combination of both, at the company’s election. Any conversion into shares will depend on stockholder approval for an increase in the authorized common stock.

In connection with the pricing, TeraWulf said it expects to enter into capped call transactions with financial institutions, designed to reduce potential dilution of its common stock upon conversion.

These institutions or their affiliates may purchase shares or enter derivative positions in the company’s stock to hedge their exposure, which could affect market prices of both the shares and the notes.

The securities have not been registered under the Securities Act and may only be offered in the U.S. under an applicable exemption. The company noted that the offering’s completion depends on market conditions.

Options to Repurpose Data Centers

Bitcoin mining companies are seeking new financing channels to scale operations amid rising competition for computing power. Access to capital markets through convertible notes provides miners with funding flexibility without immediately diluting shareholders, a strategy several peers have also employed.

Analysts are watching whether expanded data center investments could strengthen miners’ positioning in the broader digital infrastructure sector.

With demand for high-performance computing growing across artificial intelligence and blockchain applications, the ability to allocate capacity beyond cryptocurrency mining could shape longer-term revenue models.
