Fortitude will draw its new $50 million credit line in the coin it mines
The undrawn $31 million of Fortitude's enlarged facility is to be taken in ZEC, putting part of the cost of capital on the same price as the revenue, ahead of a planned Nasdaq listing. The original line cost 11 percent.
The Investor · Invest desk
What happened
- Fortitude Mining Holdings, a Digital Currency Group subsidiary, lifted its credit facility from $26 million to $50 million on September 23, 2026, adding 92 percent to its borrowing capacity.
- Roughly $31 million of the enlarged facility is undrawn, and Fortitude plans to pull it down in ZEC instead of dollars, with further ZEC-denominated draws contemplated through fiscal 2027.
- The stated use of proceeds is 9,000 Bitmain Antminer Z15 Pro machines, together with new data centers and the power infrastructure to run them.
- Fortitude has announced a business combination with Nasdaq-listed HeartSciences that would take it public under the ticker TUDE.
Compiled by The InvestorSomething wrong?How this is made
Why it matters
- decision Additional ZEC-denominated draws are authorized through fiscal 2027, so every tranche becomes a timing call on the coin's price on the day it is taken, made by a company whose revenue is that same coin.
- contradiction cryptobriefing presents the ZEC draw as a natural hedge, and the same report has the facility secured on equipment and real estate, so a fall in the coin relieves the principal and impairs the security at once.
- exposure Should the HeartSciences deal close, public shareholders arriving under the TUDE ticker inherit a liability quoted in Zcash and due June 2028, and its terms get priced in the deal documents.
- constraint Owning the sites is central to the roughly $40 per coin target. The margin case rests on capital sunk into buildings and power that cannot be moved if the economics change.
Subtract the roughly $31 million still available from the $50 million ceiling and about $19 million has been drawn since June 1 [1][4][2]. The line before the amendment was $26 million, so roughly $7 million of it was untouched when Fortitude went back for more [1][3]. The request came under four months after signing [8][2][4].
Nine thousand Z15 Pro machines against $31 million is about $3,400 apiece [5][4][5]. The same money is meant to build new data centers and power infrastructure [5], so the hardware budget sits below that.
The original facility costs 11 percent and matures in June 2028, secured against the acquired equipment and select real estate [8]. That maturity is 21 months out from the amendment [8]. Eleven percent on a fully drawn $50 million is $5.5 million a year [6], and at the roughly $40 per ZEC that Fortitude targets as its mining cost, $5.5 million is the cost of producing 137,500 coins [7][9]. cryptobriefing does not name the lender, and it does not say whether the enlarged facility keeps the 11 percent rate [13].
Fortitude is buying the machines with 11 percent coin-denominated debt, and the equity it could issue into the HeartSciences combination goes unused [10].
Fortitude has crossed 60 megawatts across its U.S. sites, 12 of those megawatts added at Grand Island, Nebraska and 12.5 at Prosser [6]. Sixty megawatts running full-time at the $0.045 per kilowatt-hour rate the company optimizes for is about $23.7 million of electricity a year [7][7]. Electricity is billed in dollars. cryptobriefing calls the ZEC draw a natural hedge, on the reasoning that a rising ZEC price lifts the dollar value of the loan and the dollar value of production together, and that the reverse holds on the way down [12].
In a rally the ZEC draw is the expensive capital in hindsight, because the dollar cost of the machines is already fixed while the coins owed cost more dollars to buy back, and that appreciation accrues to the lender [4]. In a drawdown it works the other way, with the principal falling alongside the coin, though the security behind it is equipment built for one algorithm, Equihash [8][11]. Coverage decides which of those matters more. If annual output is several multiples of 137,500 coins, whether the loan is owed in coin or in dollars barely matters, and if it is close to that, June 2028 is a refinancing question [8][9].
What to watch
- Whether the HeartSciences combination closes, and what the merger disclosure says about the lender and the amended interest rate.
- The size and timing of the first additional ZEC-denominated draw authorized through fiscal 2027, and ZEC's price on the day it is taken.
- Any production or hashrate figure from Fortitude that would let the 11 percent coupon be measured against annual coin output.
