Horizon Quantum completes its dMY Squared SPAC merger and begins trading on Nasdaq (HQ), raising ~$120M
On 2026-03-20 Horizon Quantum Computing - a developer of software infrastructure for quantum applications - completed its business combination with dMY Squared Technology Group (shareholders approved 2026-03-17) and began trading on Nasdaq under the ticker HQ (warrants HQWWW), with approximately $120 million in gross proceeds to fund R&D, its hardware testbed and its Triple Alpha integrated development environment. This consummates the 2025-12-05 PIPE-supported combination.
Completing the SPAC listing converts Horizon's go-public plan into ~$120M of public capital for its quantum-software-and-IDE roadmap, adding another listed quantum-software name; it is a completed, principal-confirmed capital event in the mid band given the modest proceeds.
A public listing funds Horizon's compiler/IDE (Triple Alpha) and hardware-testbed strategy and gives the quantum-software layer another public comparable alongside Classiq's private financings; execution against the Beryllium/Triple Alpha roadmap is the proof point.
