Analysis · HVII · Energy & Transportation
The development pipeline for ONE Nuclear, the target in HVII's pending $1B SPAC merger, has grown from a single announced project (Cayman) to a three-project, 5 GW Louisiana portfolio. The newly disclosed Amberjack SMR campus (1 GW) and Barracuda integrated datacenter energy park (1.2 GW) materially broaden the combined company's addressable opportunity and development risk profile. All figures are planning-level targets subject to permitting, financing, and customer contracts; no construction decisions have been made. The announcement comes two weeks after HVII shareholders approved the merger and just weeks before the September 30, 2026 merger deadline, reinforcing the growth narrative ahead of the anticipated close in H2 2026.
