• The ability of Horizon Quantum's coding languages to provide additional abstraction when compared to other quantum computing solutions.
• The ability to successfully or timely consummate the private placement of an aggregate of approximately $110 million of Holdco's Class A ordinary shares.
• The entry into the Side Letter, dated December 4, 2025, among Horizon Quantum, Holdco, dMY, and IonQ, Inc., and the ability to recognize its benefits.

Future Outlook

Horizon Quantum expects Beryllium to provide higher levels of abstraction and utility to its users and be portable across any hardware system. The company also expects to integrate access to its testbed with its Triple Alpha system. The overall mission is to unlock broad quantum advantage by building software infrastructure that empowers developers to use quantum computing to solve complex computational problems.

Management Comments

• "At Horizon Quantum, we believe that enabling conventional software developers to harness quantum computers will be key to unlocking new applications." Dr. Joe Fitzsimons, founder and CEO of Horizon Quantum.
• "We believe Beryllium is an important milestone, as we introduce the abstraction needed to bridge the gap between classical and quantum programming." Dr. Joe Fitzsimons.

Industry Context

The announcement positions Horizon Quantum as a pioneer in software infrastructure for quantum applications, aiming to bridge the gap between classical programming and quantum computing. The introduction of Beryllium, a high-level, hardware-agnostic language, addresses a key industry challenge: making quantum computing more accessible to a broader developer base beyond quantum experts. This aligns with a broader industry trend towards developing more user-friendly tools and abstraction layers to accelerate quantum software development and adoption.

Comparison to Industry Standards

• Beryllium's object-oriented and hardware-agnostic design aims to provide higher levels of abstraction compared to existing lower-level quantum programming solutions, which often require deep quantum expertise and are hardware-specific.
• The integration of Beryllium into Horizon's Triple Alpha IDE, alongside languages like Helium (BASIC-like for concurrent classical/quantum workflow) and Hydrogen (assembly-like for general control flow), suggests a more comprehensive and layered approach to quantum software development than many single-language or hardware-bound offerings.
• The focus on "information structure rather than qubits and low-level processing details" directly contrasts with the current state of much quantum programming, which often necessitates direct management of quantum states and hardware specifics.

Stakeholder Impact

• **Developers/Programmers**: Beryllium aims to make quantum software development more accessible, reducing the need for deep quantum expertise, thereby expanding the pool of potential quantum developers.
• **Shareholders (dMY)**: The Business Combination and the associated private placement could impact the value of their shares. They will also vote on the Business Combination.
• **Investors**: The announcement provides insight into Horizon Quantum's technological progress and strategic direction, which is relevant for investment decisions.
• **Quantum Computing Industry**: The development of high-level, hardware-agnostic languages like Beryllium could accelerate the adoption and practical application of quantum computing.

Next Steps

• Horizon Quantum will preview Beryllium this week at Q2B Silicon Valley.
• Horizon Quantum will introduce additional technological progress across its software stack at Q2B Silicon Valley.
• Horizon Quantum Holdings Ltd. (Holdco) and Horizon Quantum will file a registration statement on Form F-4 relating to the Business Combination.
• After the Registration Statement is declared effective, dMY will mail a definitive proxy statement/prospectus to its shareholders for voting on the Business Combination.
• A special meeting of shareholders of dMY will be held to vote on the Business Combination.
• dMY, Holdco, and Horizon Quantum may file other documents with the SEC regarding the Business Combination.
