Quantinuum Files Preliminary S-1 for Proposed IPO, Discloses Financials and Structure
Quantinuum, a vertically integrated quantum computing company formed by the merger of Honeywell Quantum Solutions and Cambridge Quantum, has publicly released a preliminary S-1 filing with the U.S. SEC for a proposed Initial Public Offering. While share pricing remains undisclosed, the filing reveals significant financial and structural details. For the fiscal year ended December 31, 2025, Quantinuum reported $30.9 million in net revenue against a $192.6 million net loss, with $79.3 million in bookings. The company holds $677 million in cash after investing over $2 billion in R&D. The IPO will utilize an Up-C structure, featuring a Tax Receivable Agreement requiring payments to continuing unitholders, primarily Honeywell and Cambridge Quantum shareholders. Honeywell retains controlling influence with 55% ownership pre-IPO and rights to designate board members. The filing also highlights a product roadmap including the Lumos processor, targeted for release post-2030 with over one million physical qubits. Key risk factors include heavy customer concentration, with RIKEN accounting for 60% of 2025 revenue, and dependencies related to national security agreements governing sensitive quantum technologies.
