Beginning in September SEALSQ will enter the second phase of deploying its $200 million budgeted allocation of capital, an internal strategic initiative through which SEALSQ allocates its own capital resources, targeting strategic Quantum assets to further strengthen and scale the platform and accelerate development of its post-quantum and quantum technology capabilities.   Second Phase of Deployment of the $200 Million Commitment Begins in September Building on the more than $65 million already deployed out of the SEALQuantum.com initiative’s $200 million budget allocation, an additional $100 million has been earmarked for closing through the end of 2027. SEALSQ confirmed that, starting in September 2026, SEALQUANTUM.com will begin the second phase of allocation of its $200 million Quantum initiative. This next phase is intended to add further strategic assets to the Quantum Vertical Sovereign Stack, extending the ecosystem's coverage across post-quantum semiconductors, quantum-resistant cryptographic infrastructure, secure communications and digital identity, edge computing and embedded AI, and satellite and space-based infrastructure. The Company has identified several opportunities for these next investments, currently at various stages of discussion and negotiation. “With the Quantum Vertical Sovereign Stack, our objective is to build a scalable, sovereign quantum platform that can translate today’s capital deployment into tomorrow’s recurring revenue and strategic moat,” said Carlos Moreira, Chairman and CEO of SEALSQ. “GlobalFoundries provides a trusted, high-volume manufacturing base, while Quobly and EeroQ give us two complementary, CMOS-compatible paths to quantum processors on that same foundation. As we enter the second phase of deployment of our $200 million SEALQuantum initiative in September, our focus is on adding assets that are accretive to this Root-to-Qubit-to-Space architecture, deepen our control of critical layers in the stack, and position SEALSQ to capture the long-term economic value of the SEALQUANTUM.com ecosystem.” One Stack, Many Partners: How the Quantum Vertical Sovereign Stack Connects the Ecosystem SEALSQ's Stack is designed as a "Root-to-Qubit" architecture that links every layer of the quantum value chain, secure semiconductors, post-quantum cryptographic infrastructure, digital identity, embedded AI, and satellite and space-based infrastructure, into a single, interoperable framework. Rather than functioning on a standalone basis, portfolio companies and partners including EeroQ, Quobly, ColibriTD, IC'ALPS, WISeSat.Space, Wecan Group, Miraex and Quantix Edge Security are being progressively woven into this common Stack, each contributing a distinct technology layer that connects upward and downward to its neighbors. At the foundation of the Stack sits SEALSQ's certified secure-semiconductor and PKI base, developed together with manufacturing and process partners such as GlobalFoundries (Nasdaq: GFS) ("GF"), under a strategic Memorandum of Understanding covering secure semiconductor platforms, post-quantum cryptography and CryoCMOS technologies for quantum computing. Above that foundation, emerging quantum-processor technologies, including Quobly's silicon spin-qubit architecture and EeroQ's electrons-on-helium (eHe) architecture, plug into the same trusted, CMOS-compatible manufacturing base, while ColibriTD's quantum-as-a-service layer and IC'ALPS' ASIC design capabilities translate that hardware into deployable products. WISeSat.Space and the planned Quantum Spatial Orbital Cloud (QSOC) then extend the same root of trust into orbit, and Wecan Group and Quantix Edge Security bring quantum-resilient identity, compliance and cybersecurity services to end customers. The result is intended to be a single, auditable chain of trust running from the semiconductor wafer to the satellite constellation. Because both Quobly's silicon spin-qubit devices and EeroQ's electrons-on-helium devices are engineered for CMOS-compatible fabrication, the Quantum Vertical Sovereign Stack is designed to let both processor families draw on the same class of secure, high-volume semiconductor manufacturing and control-electronics capability that SEALSQ is developing together with GF, giving SEALSQ two complementary, industrially scalable paths to quantum hardware, wrapped in a common layer of certified secure semiconductors and post-quantum cryptography.
