Fortitude, a mining company spun out from Foundry, plans to go public on Nasdaq through a merger with HeartSciences, with the combined company expected to trade under the ticker TUDE. According to Foresight News, The Wall Street Journal reported that the transaction is expected to be completed in the second half of 2026.

Fortitude was established in early 2025 after being separated from the self-mining division of Foundry, a mining company under Digital Currency Group (DCG). The company’s business includes seeking early proof-of-work (PoW) emerging token opportunities described as high-growth and high-return.

The report also said Fortitude is one of the largest miners of Zcash.
