Cipher Digital Inc. (NASDAQ: CIFR) shares fell nearly 13% on Tuesday after the data center developer announced plans to raise $850 million through zero-interest convertible debt due in 2032 while separately preparing to exchange part of its existing 2030 notes for common stock.
The stock closed at $11.34 after touching a new 52-week low of $10.68. Trading volume reached approximately 123.5 million shares, nearly 3.7 times its 90-day average of 33.43 million, as the financing announcement brought the company’s capital requirements and potential shareholder dilution into focus.
The proposed financing comes as Cipher estimates it needs approximately $750 million in additional project equity to support its expanded Barber Lake data center agreement, which extends the property’s contracted lease term to 20 years.
$850 Million Offering Supports Barber Lake’s Expanded Funding Needs
According to the press release, the company plans to sell $850 million in senior unsecured convertible notes to qualified institutional buyers, with the offering’s initial purchasers receiving an option to buy another $150 million. Full exercise would increase the offering to $1 billion.
The notes will pay no regular interest and mature on November 1, 2032, unless converted, redeemed or repurchased earlier. Investors holding the new bonds can also require Cipher to buy them back for cash at face value on November 1, 2030, subject to the offering’s terms.
The principal remains a repayment obligation unless the notes are converted or otherwise settled. Cipher can settle conversions in cash, common shares, or a combination of both, meaning any dilution from the new notes would depend on the settlement method and the number of shares ultimately issued.
Cipher intends to use part of the proceeds for capped-call transactions designed to reduce potential share dilution when the notes convert. The remaining funds will support additional equity investment in Barber Lake, construction across its high-performance computing pipeline, development-site expansion, and general corporate purposes.
The funding requirement follows Cipher’s September amendment to its existing 10-year Barber Lake lease with Fluidstack and a separate binding commitment with a leading AI lab to lease the facility for the following decade. Together, the arrangements bring Barber Lake’s aggregate contracted term to 20 years. The expansion increased expected contracted revenue at the Texas facility from approximately $3.8 billion to $9.1 billion, including $5.2 billion tied to the additional decade.
In its October investor presentation, Cipher estimated approximately $750 million of additional project equity would be required to support the lease expansion and associated costs. That amount is a project-level funding estimate, rather than a disclosed allocation of the entire convertible offering.
The expanded agreement also includes a construction-cost-sharing arrangement negotiated with Fluidstack and the AI lab. Cipher’s October investor presentation lists Barber Lake’s original project budget at $2.157 billion. Cipher will bear the first $359.3 million in costs above the initial budget, while 50% of further excess costs will be reimbursed through additional rent over the 20-year contracted period.
Concurrent 2030 Debt Exchange Adds a Separate Dilution Consideration
Alongside the offering, Cipher expects to enter into privately negotiated agreements with a limited number of holders of its outstanding 1.75% convertible senior notes due May 15, 2030, who would exchange a portion of those notes for Cipher common shares.
The company reported $172.5 million in outstanding principal on the 2030 convertible notes as of June 30, according to its second-quarter SEC filing. It has not disclosed how much of that balance will be exchanged or how many shares participating holders will receive.
The transaction would reduce debt principal and related interest obligations on the exchanged notes, but it would also increase the number of common shares outstanding. Unlike the potential dilution associated with the new 2032 bonds, these shares would be issued directly through the exchange.
The planned capped calls, designed to reduce conversion-related dilution on the new notes subject to a cap, would not cover shares issued through the separate 2030 debt exchange.
The company also cautioned that participating bondholders and financial institutions involved in the capped calls may buy or sell shares or adjust hedging positions as the transactions proceed, potentially affecting the stock’s trading price.
The proposed offering remains subject to market conditions. Final conversion pricing, the size of the 2030 debt exchange, and the number of shares ultimately issued have not yet been established, leaving the financing package’s full impact on Cipher’s capital structure undetermined.
