**Horizon Quantum Announces First Quarter 2026 Financial Results** 

May 5, 2026

 

**SINGAPORE** — **(BUSINESS WIRE)** — **May 5, 2026** — Horizon Quantum Holdings Ltd. (Nasdaq: HQ) ("Horizon Quantum," "we," "us," or "our"), a pioneer of software infrastructure for quantum applications, today reported financial results for the fiscal quarter ended March 31, 2026.

**First Quarter and Recent Business Highlights (all figures presented in USD):**

● Successful completion of a business combination with dMY Squared Technology Group, Inc., with trading on Nasdaq commencing on March 20, 2026 in Horizon Quantum's Class A Ordinary Shares and Warrants under ticker symbols "HQ" and "HQWWW," respectively.

● Operating loss for the first quarter of 2026 on an as-reported basis of $6.5 million compared to $4.7 million for the first quarter of 2025.

● Net loss for the first quarter of 2026 on an as-reported basis of $3.6 million, or $0.09 per ordinary share, compared to a loss of $4.8 million in the prior year, or $0.12 per ordinary share in the first quarter of 2025.

● Adjusted EBITDA was a loss of $4.1 million as compared to a loss of $1.8 million in the first quarter of 2025.

● Cash and cash equivalents were $96.6 million on March 31, 2026.

● A strategic agreement with IonQ has been announced, which includes the purchase of a 256-qubit trapped-ion quantum computer. Horizon Quantum believes this strengthens its hardware testbed capabilities by adding a frontier system alongside its existing superconducting system.

● AQT collaboration announced seeking to integrate a leading European trapped-ion provider's hardware with Horizon Quantum's software infrastructure.

● Alice & Bob collaboration announced seeking to integrate A&B's emulated cat qubit system with Triple Alpha to facilitate the development and deployment of fault-tolerant quantum software.

**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 Completion of 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) - Triple Alpha**

 

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

 

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

● <u>Object-oriented quantum programming:</u> In the first quarter of 2026, Horizon Quantum's research and development efforts included extending Beryllium, Triple Alpha's object-oriented programming language, to a more stable and feature-complete state following its initial preview in December.

● <u>Testbed improvements:</u> First quarter 2026 research and development efforts also involved preparing Horizon Quantum's testbed system, Ember-1, for use by Triple Alpha early access users.

**Hardware Partners**

 

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

● <u>Alice & Bob - fault-tolerant computing collaboration:</u> In January 2026, Horizon Quantum announced a strategic collaboration with Alice & Bob, a leading developer of fault-tolerant quantum computers, to integrate their cat qubit emulators with Triple Alpha. This collaboration is intended to streamline the development of fault-tolerant quantum software, helping to position Horizon Quantum's Triple Alpha as one of the first platforms to be able to deploy applications to Alice & Bob's planned, error-correction-capable, quantum processing units.

● <u>IonQ - strategic agreement to unlock quantum potential:</u> In April 2026, Horizon Quantum announced a strategic agreement with IonQ, including the purchase of a 256-qubit trapped-ion system. This will position Horizon Quantum as one of a very small number of efforts globally to operate commercial quantum systems of multiple modalities, and it is expected to allow Horizon Quantum to make further progress towards its goal of building the most capable, hardware-agnostic quantum software development tools.

● <u>AQT - hardware collaboration:</u> In April 2026, Horizon Quantum announced a strategic collaboration with AQT (Alpine Quantum Technologies) involving the integration of Triple Alpha with AQT's trapped-ion quantum processors to leverage synergies between the two companies. The collaboration will allow developers to use Triple Alpha to write, compile, and deploy quantum programs directly onto AQT processors.

**Testbed**

 

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

● <u>Initial testbed system - Industry-first hardware integration testbed</u>: 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.

● <u>Second testbed system - tightly integrating Triple Alpha with a frontier quantum computing system</u>: 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.

**First Quarter Financial Results** 

All results presented prior to the closing of the business combination on March 19, 2026, reflect the financial results of Horizon Quantum Computing Pte. Ltd. Results as of March 31, 2026, reflect those of Horizon Quantum Holdings Ltd.

● Total operating expenses for the first quarter of 2026 were $6.5 million compared to $4.7 million for the first quarter of 2025.

● R&D expenses for the first quarter of 2026 were $2.1 million compared to $3.3 million for the first quarter of 2025, representing a decrease of 36%. The decline was largely due to a one-time share-based compensation catch-up expense of $2.5 million in the first quarter of 2025. Excluding the one-time share-based compensation expense, R&D expenses increased 135% from a year ago driven by increased hiring of scientists and engineers and costs from the setup of the hardware testbed.

● Sales and marketing expenses for the first quarter of 2026 were $0.5 million, up 40% year over year compared to $0.3 million for the first quarter of 2025. When excluding share-based compensation of $0.05 million and $0.1 million respectively from each period, the year-over-year increase in sales and marketing was 85% and was attributable to increases in trade show activity and industry engagement.

● General and administrative expenses for the first quarter of 2026 were $3.6 million compared to $0.9 million for the first quarter of 2025, representing an increase of 300%. Excluding share-based compensation and one-time business combination expenses of $1.9 million and $0.3 million from the first quarter of 2026 and 2025, respectively, G&A increased 191% year over year. The year-over-year expense increase was due to needed increases in headcount and systems associated with becoming a public company.

● Reported operating loss for the first quarter of 2026 was $6.5 million compared to $4.7 million for the first quarter of 2025, representing an increase of $1.8 million, primarily due to increased hiring.

● Reported net loss for the first quarter of 2026 was $3.6 million, or $0.09 per ordinary share, as compared to a net loss of $4.8 million, or $0.12 per ordinary share, in the first quarter of 2025. EBITDA for the first quarter of 2026 was a $3.3 million loss versus a $4.7 million loss in the first quarter of 2025. Adjusted EBITDA, which excludes share-based compensation, change in fair value of derivative liabilities and one-time expenses related to the business combination, was a $4.1 million loss as compared to a $1.8 million loss in the first quarter of 2025.

● Recognized a non-cash gain of $3.0 million for the first quarter of 2026, of which a $2.3 million loss attributed to fair value remeasurement and subsequent settlement of SAFE liabilities into Horizon Quantum's Class A ordinary shares was offset by a $5.3 million gain attributed to fair value remeasurement of DMY's warrant liabilities assumed by Horizon Quantum at the close of the business combination.

● Cash and cash equivalents were $96.6 million as of March 31, 2026, an increase of $96.4 million from $0.2 million as of December 31, 2025. The increase in cash and cash equivalents was the result of the PIPE transaction and business combination which closed on March 19, 2026.

**Conference Call Information**

As previously announced, the company will hold a conference call to discuss its first quarter on May 5 at 8:00 a.m. ET. The conference call will be broadcast live over the internet and can be accessed at https://investors.horizonquantum.com/news-events. For those unable to listen to the live broadcast, an archived version will be available at the same location for one year.

**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.
