CEO Commentary

“Rapid advancement in quantum computing hardware coupled with recent breakthroughs in error correction may suggest the field is reaching an inflection point, with quantum advantage drawing nearer. We believe that the successful completion of our business combination with dMY Squared Technology Group, Inc., will allow us to significantly accelerate progress in building the software infrastructure to power quantum applications. We anticipate that the business combination has provided us with the financial runway required to support our strategic priorities for the foreseeable future, while enabling increased investments in R&D, allowing us to advance our integrated development environment, Triple Alpha, and push towards quantum advantage with the extension of our testbed. Together, we believe these initiatives will significantly strengthen our ability to unlock the full potential of quantum computing, positioning us to develop and grow revenue as the industry drives towards quantum advantage,” said Horizon Quantum CEO and Founder Dr. Joe Fitzsimons.

He continued, “During the first quarter in 2026, we became a public company and made meaningful progress on several fronts. We enhanced the stability and feature set of our object-oriented programming language Beryllium. We announced collaborations with leading hardware providers Alice & Bob and AQT, and we inaugurated the first quantum system in our hardware testbed. We also announced the purchase of our second quantum system, one that may very well be capable of solving some challenging computational problems. Taking the step of hosting both solid-state and atom-based systems provides us with a multi-modality testbed that few commercial organizations can match. It allows us to build quantum software infrastructure that is genuinely hardware-agnostic, not because it ignores the hardware, but because it is developed in direct contact with very different quantum computing technologies.”

Successful Completionof Business Combination

●

During the first quarter of 2026, Horizon Quantum announced that it completed its previously announced business combination with dMY Squared Technology Group, Inc., a publicly traded special purpose acquisition company. The Business Combination was approved by dMY’s shareholders at dMY’s special meeting held on March 17, 2026. On March 20, 2026, the combined company’s Class A ordinary shares and warrants began trading on Nasdaq under the ticker symbols “HQ” and “HQWWW”, respectively.

Operational Highlights

Integrated Development Environment (IDE) - TripleAlpha

Triple Alpha—Horizon Quantum’sintegrated development environment—enables developers to build complex, hardware-agnostic quantum programs. Built with proprietaryTuring-complete languages and an optimizing compiler, it empowers programmers to work at multiple levels of abstraction.

Triple Alpha gives developers access to advancedcapabilities supported by Horizon Quantum’s underlying execution and deployment infrastructure. Users can code, compile, and optimizeprograms across a range of processors and simulators, with built-in resource analysis and single-step API deployment.

●	Object-oriented quantum programming: In the first<br>quarter of 2026, Horizon Quantum’s research and development efforts included extending Beryllium, Triple Alpha’s object-oriented<br>programming language, to a more stable and feature-complete state following its initial preview in December.
●	Testbed improvements: First quarter 2026 research<br>and development efforts also involved preparing Horizon Quantum’s testbed system, Ember-1, for use by Triple Alpha early access<br>users.
---	---

Hardware Partners

By tightly integrating its software infrastructurewith a variety of hardware platforms, Horizon Quantum aims to provide developers with the most direct path to broad quantum advantageand help ensure that their quantum applications remain useful—no matter which modality emerges as a frontrunner.

●	Alice<br> & Bob - fault-tolerant computing collaboration: In January 2026, Horizon Quantum<br> announced a strategic collaboration with Alice & Bob, a leading developer of fault-tolerant<br> quantum computers, to integrate their cat qubit emulators with Triple Alpha. This collaboration<br> is intended to streamline the development of fault-tolerant quantum software, helping to<br> position Horizon Quantum’s Triple Alpha as one of the first platforms to be able to<br> deploy applications to Alice & Bob’s planned, error-correction-capable, quantum<br> processing units.
●	IonQ<br> - strategic agreement to unlock quantum potential: In April 2026, Horizon Quantum announced<br> a strategic agreement with IonQ, including the purchase of a 256-qubit trapped-ion system.<br> This will position Horizon Quantum as one of a very small number of efforts globally to operate<br> commercial quantum systems of multiple modalities, and it is expected to allow Horizon Quantum<br> to make further progress towards its goal of building the most capable, hardware-agnostic<br> quantum software development tools.
---	---
●	AQT - hardware<br> collaboration: In April 2026, Horizon Quantum announced a strategic collaboration with<br> AQT (Alpine Quantum Technologies) involving the integration of Triple Alpha with AQT’s<br> trapped-ion quantum processors to leverage synergies between the two companies. The collaboration<br> will allow developers to use Triple Alpha to write, compile, and deploy quantum programs<br> directly onto AQT processors.
---	---

Testbed

Horizon Quantum is currently the only quantumsoftware company to operate its own quantum computer. This gives Horizon Quantum full control over both quantum hardware and softwarestacks, providing a testbed for the integration of its software directly with hardware systems, and allowing Horizon Quantum to developreal-time execution capabilities that go beyond what is possible over cloud connections. This represents a possible critical advantagein pursuing quantum advantage, where tight integration between hardware and software is expected to be critical to early success. Withthe acquisition of a second testbed system, Horizon Quantum intends to extend its hardware capabilities beyond solid state qubits to alsoencompass atom-based systems. The anticipated performance of the new system is expected to be an important resource for both in-housescientists and external Triple Alpha users pursuing quantum advantage.

●

Initial testbed system - Industry-first hardware integration testbed: In January 2026, Horizon Quantum held the inauguration of its first quantum computer, Ember-1, having completed the assembly and integration of a fully operational, multi-vendor system at its Singapore headquarters. This system gives Horizon Quantum full control of both the quantum hardware and software stacks, allowing the company to integrate its software infrastructure directly with control systems, and avoiding latency issues that prevent fast feed-forward operations in remote settings.

●

Second testbed system - tightly integrating Triple Alpha with a frontier quantum computing system: In April 2026, Horizon Quantum announced its purchase of IonQ’s 6th-generation, chip-based 256-qubit trapped-ion system. With this, Horizon Quantum plans to expand the capabilities of its quantum hardware testbed beyond its initial superconducting system with a second, technologically distinct hardware modality. This is anticipated to allow Horizon Quantum to expand support for trapped-ion systems in Triple Alpha and to enhance the real-time runtime capabilities within its execution infrastructure. Horizon Quantum expects to enable advanced execution functionality, including support for general control flow, dynamic memory allocation, and concurrent classical and quantum function evaluation, aiming to empower developers to go beyond the limits of static circuit execution and create adaptive, expressive quantum programs.

Non-GAAP Financial Measures

To supplement Horizon Quantum’s condensed financial statements presented in accordance with GAAP, the Company uses non-GAAP measures of certain components of financial performance. EBITDA and Adjusted EBITDA are financial measures that are not required by or presented in accordance with GAAP. Management believes that these measures provide investors an additional meaningful method to evaluate certain aspects of the company’s results period over period. EBITDA is defined as net loss before net interest income or expense, depreciation and amortization expenses, and income tax expense and Adjusted EBITDA is defined as net loss before net interest income or expense, depreciation and amortization expenses, income tax expense, share-based compensation, change in fair value of derivative liabilities and non-recurring business combination expenses. The Company uses EBITDA and Adjusted EBITDA to measure the operating performance of its business, by excluding specifically identified items that management does not believe directly reflect the Company’s core operations and may not be indicative of its recurring operations. The presentation of non-GAAP financial measures is not meant to be considered in isolation or as a substitute for the financial results prepared in accordance with GAAP, and the Company’s non-GAAP measures may be different from non-GAAP measures used by other companies. For Horizon Quantum’s investors to be better able to compare its current results with those of previous periods, the Company has shown a reconciliation of GAAP to non-GAAP financial measures at the end of this release.
