quantum-computingHorizon Quantum clarifies details of its March merger
Horizon Quantum Computing has clarified details regarding its share structure following a period of market uncertainty. As of September 14, 2026, the company reports 34,811,740 Class An Ordinary Shares and 19,744,585 Class B Ordinary Shares outstanding. These shares are subject to lock-up agreements extending until March 19, 2028, for most shareholders, with one agreement expiring earlier on September 19, 2027, following the March 2026 merger with dMY Squared Technology Group. Founded in 2018 and now publicly listed on Nasdaq, Horizon Quantum develops software tools translating classical code into quantum circuits and operates its own quantum hardware. Business Combination Lock-Up Agreements Extend to March 19, 2028 Lock-up agreements extend to March 19, 2028, for the majority of Horizon Quantum’s shareholders, a detail clarified following recent market activity. The lock-up period, lasting twenty-four months after the merger’s close, aims to maintain market stability and demonstrate long-term investor confidence in Horizon Quantum’s trajectory, the company says. This timeframe aligns with standard practices for companies emerging from special purpose acquisition company (SPAC) mergers, providing a buffer against immediate selling pressure. One shareholder benefits from an earlier release, with their lock-up agreement expiring eighteen months after the closing date, or September 19, 2027. The company’s decision to publicly address these agreements comes after a period of market uncertainty, proactively assuring investors of the existing restrictions on share sales. This transparency is particularly relevant given Horizon Quantum’s status as the first publicly traded company focused solely on quantum software, a field attracting significant investment and attention.
