Cautionary Note Regarding Forward-Looking Statements

 

This Current Report on Form 8-K and the exhibit hereto include “forward-looking statements” with respect to dMY, Holdco, and Horizon. The expectations, estimates, and projections of the businesses of Holdco, Horizon and dMY may differ from their actual results and consequently, you should not rely on these forward-looking statements as predictions of future events. Words such as “expect,” “estimate,” “anticipate,” “intend,” “may,” “will,” “could,” “should,” “potential,” “plan” and similar expressions are intended to identify such forward-looking statements. Forward-looking statements involve significant risks and uncertainties that could cause the actual results to differ materially from the expected results and are subject to, without limitation, (i) known and unknown risks, including the risks and uncertainties indicated from time to time in the dMY Annual Report, dMY’s other filings with the SEC, and the Registration Statement and Proxy Statement, including those under “Risk Factors” therein, and other documents filed or to be filed with the SEC by dMY, Holdco, or Horizon; (ii) uncertainties; (iii) assumptions; and (iv) other factors beyond dMY’s, Holdco’s, or Horizon’s control that are difficult to predict because they relate to events and depend on circumstances that will occur in the future. They are neither statements of historical fact nor promises or guarantees of future performance. Therefore, actual results may differ materially and adversely from those expressed or implied in any forward-looking statements and dMY, Holdco, and Horizon therefore caution against placing undue reliance on any of these forward-looking statements.

 

Many of these factors are outside of the control of dMY, Holdco, and Horizon and are difficult to predict. Factors that may cause such differences include, but are not limited to: (1) the occurrence of any event, change or other circumstances that could give rise to the termination of the business combination agreement, dated as of September 9, 2025, by and among dMY, Horizon and Holdco and the other parties thereto (the “Business Combination Agreement”); (2) the ability to successfully or timely consummate the private placement of an aggregate of approximately $111.9 million of Holdco’s Class A ordinary shares with certain institutional and accredited investors, qualified institutional buyers and strategic investors (the “PIPE Transaction”); (3) the outcome of any legal proceedings that may be instituted against the parties following the announcement of the Business Combination and the Business Combination Agreement; (4) the inability to complete the Business Combination, including due to the failure to obtain approval of the shareholders of Horizon and dMY or other conditions to closing the Business Combination; (5) changes to the structure of the Business Combination that may be required or appropriate as a result of applicable laws or regulations or as a condition to obtaining regulatory approval of the Business Combination; (6) Holdco’s ability to scale and grow its business, including through the use of proceeds of the PIPE Transaction, and the advantages and expected growth of Holdco; (7) the cash position of Holdco following the closing of the Business Combination; (8) the inability to obtain or maintain the listing of Horizon Quantum’s securities on the New York Stock Exchange, the NYSE American, or Nasdaq following the Business Combination; (9) the risk that the announcement and pendency of the Business Combination disrupts Horizon’s current plans and operations; (10) the ability to recognize the anticipated benefits of the Business Combination and PIPE Transaction, which may be affected by, among other things, competition, the ability of Holdco to grow and manage growth profitably and source and retain its key employees; (11) costs related to the Business Combination; (12) changes in applicable laws and regulations or political and economic developments; (13) the possibility that Holdco may be adversely affected by other economic, business and/or competitive factors; (14) Holdco estimates of expenses and profitability; (15) the amount of redemptions by dMY public shareholders; (16) difficulties operating Holdco’s quantum processor and the possibility that the quantum processor does not provide the advantages that Holdco expects; (17) the ability to successfully or timely consummate the PIPE Transaction; (18) the ability of Holdco to integrate access to its quantum computing test bed within its Triple Alpha platform; (19) the ability of our coding languages to provide additional abstraction when compared to other quantum computing solutions; (20) the entry into the Side Letter and our ability to recognize the benefits of the Side Letter; (21) other risks and uncertainties included in the “Risk Factors” sections of the dMY Annual Report, dMY’s other filings with the SEC, and the Registration Statement and other documents filed or to be filed with the SEC by Holdco, Horizon and dMY. The foregoing list of factors is not exclusive. You should not place undue reliance upon any forward-looking statements, which speak only as of the date made. Holdco, Horizon and dMY do not undertake or accept any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements to reflect any change in their expectations or any change in events, conditions, or circumstances on which any such statement is based, except as required by law.

Horizon Quantum Delivers Achievements that Demonstrate Company’s Momentum in the Quantum Industry

 

SINGAPORE AND LAS VEGAS, NV, March 10, 2026 — Horizon Quantum Computing Pte. Ltd. (“Horizon Quantum”), a pioneer of software infrastructure for quantum applications, has recently achieved a number of important milestones as it seeks to complete its proposed business combination (the “Business Combination”) with dMY Squared Technology Group, Inc. (“dMY”) (OTC: “DMYY”, “DMYYU” and “DMYYW”).

 

“Horizon has made great progress in recent months in strengthening our operations and governance and further advancing our mission to build software infrastructure for the quantum industry,” said Horizon Quantum Founder and CEO Dr. Joe Fitzsimons. “We are excited to be nearing the completion of our business combination with dMY and believe these recent developments will position Horizon for success as a publicly-traded company.”

 

Recent Business Highlights

 

Horizon has achieved significant milestones as it prepares to complete the Business Combination:

 

  Oversubscribed PIPE financing with strategic investors: More than doubled original PIPE target of $50mn, with lead investors including (a) IonQ, one of the world’s leading quantum computing companies; (b) a Fortune 50 technology company; and (c) several leading institutional investors. The larger PIPE is expected to enable the acceleration of investments in research and development, the strengthening of Horizon Quantum’s hardware testbed, and further advances of Triple Alpha, Horizon Quantum’s web-based integrated development environment (IDE) for writing complex quantum software.

 

  Announces expected world-class appointments to the board of directors of Horizon Quantum Holdings Ltd. (“Horizon”), which will become the holding company of Horizon Quantum:

 

  Danielle Lambert, the former VP of Human Resources at Apple, who helped build out key teams including iPod, iPhone, iPad and Apple Retail Stores. She later played a pivotal role in the founding of Nest Labs Inc., as an investor and advisor through the company’s rapid growth and acquisition by Alphabet Inc.

 

  Peter Oey, the Chief Financial Officer of Grab, a prominent Southeast Asia superapp. He previously served as CFO of LegalZoom.com Inc. prior to its IPO and as CFO of MyLife.com Inc. Earlier in his career he held several finance leadership roles at Activision Blizzard Inc.

 

  Jill Turner, the Chief Human Resources Officer of Broadcom, has more than 20 years of experience in global human resources leadership roles in Fortune 500 technology companies. She previously held executive positions at Honeywell International Inc. and Lumen Technologies Inc. (formerly CenturyLink Inc.).

 

  Harry You, the Chairman of dMY, is also a member of Broadcom’s board. Previously, he was Lead Independent Director of IonQ Inc. He is also an experienced public company officer, having held CFO roles at Accenture plc and Oracle Corporation and an EVP role at EMC Corporation, among others.

 

 

 

 

  Industry-first hardware integration testbed: Became the first quantum software company to own and operate a quantum computer, completing assembly and integration of a fully operational system at its Singapore headquarters, providing Horizon with a testbed system over which it has full control of both the hardware and software stack.

 

  Strategic fault-tolerant computing collaboration: Announced a strategic collaboration with Alice & Bob, a leading developer of fault-tolerant quantum computers, to integrate their cat qubit emulators with Triple Alpha. It is expected that this collaboration will position Horizon Quantum’s Triple Alpha as one of the first platforms to deploy applications to quantum processing units capable of executing quantum error correction tasks, potentially accelerating the path to scalable, fault-tolerant quantum computing.

 

  Object-oriented quantum programming: Launched Beryllium, a hardware-agnostic, object-oriented programming language that is designed to enable more efficient development of sophisticated quantum applications and allow for a greater level of abstraction. Beryllium complements Triple Alpha’s existing Helium and Hydrogen languages, seeking to provide a comprehensive software stack that bridges classical programming and quantum-accelerated implementation, with advanced capabilities including pulse-level control and direct execution on quantum hardware control systems.

 

We have been impressed by the tremendous progress Horizon has made on its strategic priorities and in bringing together a world-class team to execute on its mission to unlock the full potential of quantum computers,” said Harry You, Chairman of dMY. “We remain optimistic on the future for Horizon and believe it is well positioned to generate meaningful value for shareholders.”

 

Important Upcoming Dates:

 

dMY Squared will hold a special meeting of its stockholders on March 17, 2026, to vote on proposals related to the Business Combination. Subject to the approval of dMY’s stockholders and the satisfaction of other customary closing conditions, the transaction is expected to close during the first quarter of 2026.

 

Horizon will host a live X Spaces conversation today, Tuesday, March 10th at 1:30 ET, featuring Dr. Joe Fitzsimons, Founder and CEO of Horizon, and Niccolo de Masi, CEO of IonQ, Inc. They will discuss IonQ’s investment in Horizon and the company’s role in the evolving quantum computing ecosystem — follow @horizon_quantum and tap ‘Set Reminder’ to join.
