TeraWulf Inc.

TeraWulf Inc. (Nasdaq: WULF) is an Easton, Maryland-based owner and operator of vertically integrated, grid-connected data center campuses. Founded as a zero-carbon bitcoin miner anchored by hydro and nuclear power on the New York grid, the company has pivoted hard into high-performance computing (HPC), repositioning its flagship Lake Mariner site in Barker, NY into a turnkey colocation campus that leases critical-IT capacity to AI and hyperscale tenants under long-term contracts.

The model is that of a power landlord, not a cloud operator: TeraWulf owns the land, the grid interconnects, and the data center shells, and delivers powered, cooled, turnkey critical-IT to tenants who bring their own GPUs. Its two anchor customers are Fluidstack (an AI cloud platform whose obligations are backstopped by Google, which holds an ~14% pro-forma equity stake) and Core42, the US arm of Abu Dhabi's G42. As of Q1 2026, 60 MW was energized for Core42 at Lake Mariner, and HPC lease revenue ($21.0M) exceeded bitcoin mining revenue for the first time.

The company describes a ~2.3 GW HPC portfolio spanning Lake Mariner plus acquired or ground-leased expansion sites — Abernathy, TX (JV); Cayuga/Lake Hawkeye in Lansing, NY; Hawesville, KY (a former smelter with 480 MW of grid-connected power); and the Chesapeake/Morgantown, MD generating station (210 MW, expandable). Every Megawatt counts 1.51 GW of named, owned/committed capacity, excluding ~0.79 GW of uncommitted 'open capacity' still under evaluation.

The whole thesis is power, and the scarcity is real: large blocks of grid-connected, near-term-energizable power in interconnection-constrained markets are the binding constraint on AI buildout, and TeraWulf controls several. Lake Mariner sits on a former coal site with existing high-voltage interconnect; Hawesville KY (480 MW) and Morgantown MD (210 MW, up to 1 GW) are acquired industrial/generation sites where the power already exists. Owning the interconnect — rather than waiting years in a utility queue — is what let TeraWulf sign $3.7B of Fluidstack revenue and a Google backstop that now totals ~$3.2B. A reported contracted revenue backlog north of $12.8B against a ~$11B market cap is the bull's headline number.

The bear case is execution and the gap between paper and power. Only 60 MW (0.06 GW) is actually energized today; 462 MW is under construction against signed leases targeting 2026 delivery, and the rest of the 'portfolio' is acquired sites needing capital, FERC approval (Morgantown's data-center load interconnection is still pending), and customers it does not yet have. Q1 2026 adjusted EBITDA was negative $(4.1)M and the company posted a $427.6M net loss while carrying multi-billion-dollar debt. The equity is effectively a leveraged call option on flawless 2026 construction execution.

The differentiated risk is customer concentration dressed as diversification. Strip away the names and the backlog rests on two counterparties — Fluidstack (only creditworthy because Google stands behind it) and Core42/G42. If Google's appetite cools or Fluidstack stumbles before the backstop fully vests, the financing chain that makes the buildout bankable is exposed. Bulls say Google's 14% stake aligns incentives; bears note that a backstop is not the same as a hyperscaler signing its own name to a 10-year lease.

Owns campuses, grid interconnects and data-center shells; delivers powered, cooled critical-IT to tenants who bring their own GPUs. Not a pure land lessor (it builds and operates the facilities) but not a neocloud either — Fluidstack and Core42 own the compute.
