Welcome to our dedicated page for DMY Squared Tech SEC filings (Ticker: DMYY), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
The SEC filings of dMY Squared Technology Group, Inc. (DMYY) provide detailed information about its structure as a special purpose acquisition company and the status of its proposed business combination with Horizon Quantum Computing Pte. Ltd. As a SPAC, dMY Squared’s regulatory disclosures focus on its charter and trust arrangements, extension mechanisms, listing status, and the terms of its business combination agreements rather than on traditional operating results.
Among the most significant documents for DMYY are its current reports on Form 8‑K. These filings describe events such as the execution of the Business Combination Agreement with Horizon Quantum Computing and a Singapore holding company, the filing of investor presentations, the announcement of a PIPE financing to support the transaction, and the confidential submission of a draft registration statement on Form F‑4 by the holding company and Horizon. Other 8‑K filings detail monthly extensions of the deadline to complete an initial business combination, including the associated deposits into the trust account.
dMY Squared’s proxy materials, including its definitive proxy statement for the December 15, 2025 special meeting, explain proposals to amend the company’s charter and trust agreement. These documents outline the rationale for extending the date by which the company must consummate a business combination, the voting thresholds required for approval, and the potential consequences if the extensions are not granted.
Another key filing is the Form 25‑NSE submitted by NYSE American LLC, which documents the removal of dMY Squared’s securities from listing and registration on that exchange after the company did not complete a business combination within the exchange’s 36‑month timeframe for SPACs. Related disclosures in the proxy statement describe the subsequent trading of DMYY securities on OTC markets.

dMY Squared Technology Group, Inc. extended the deadline to complete its initial business combination by one month, moving the date from February 28, 2026 to March 29, 2026. This is the second of up to five one-month extensions the board is allowed to approve.
The company’s Amended and Restated Articles of Organization permit up to five monthly extensions, which could push the final deadline to June 29, 2026 if all are used. The extension was approved by the board of directors via resolution under this existing authority.
dMY Squared Technology Group is asking shareholders to approve a business combination with Singapore-based Horizon Quantum Computing via a new holding company, Horizon Quantum Holdings Ltd. The registration covers the issuance of up to 24,166,557 Holdco Class A ordinary shares, alongside Class B shares and warrants tied to the merger.
The deal includes an estimated $503 million equity valuation for Horizon, a PIPE investment of $110.4 million at the SPAC redemption price, and additional SAFE financing. Post‑closing, Horizon’s founder is expected to control about 64.1% of the voting power through a dual‑class structure, while public shareholders would own about 4.3% of Holdco shares and 2.5% of voting power, implying significant dilution and concentrated control.
DMY Squared Technology Group, Inc. received an amended beneficial ownership report showing that J. Goldman & Co., L.P., J. Goldman Capital Management, Inc., and Jay G. Goldman now report 0 shares of Class A common stock beneficially owned, representing 0% of the class.
The filing, dated for an event on 12/31/2025, confirms that these securities, previously held through J. Goldman Master Fund, L.P. and J. Goldman Enhanced Master Fund, L.P., are no longer beneficially owned. The reporting persons certify the holdings were in the ordinary course of business and not for influencing control of the company.
dMY Squared Technology Group, Inc. extended the deadline to complete its initial business combination by one month, moving the date from January 29, 2026 to February 28, 2026. This is the first of up to five one-month extensions the board may approve.

Horizon Quantum discusses its planned business combination with dMY Squared Technology Group and how its new quantum computer supports future growth. CEO Joseph Fitzsimons explains that the company has invested about
He notes the system is already fostering new software and hardware skills and supporting team expansion in Singapore and Ireland, although specific headcount targets are not disclosed. Horizon Quantum expects real-world quantum applications to emerge in roughly two to four years, with potential impact in chemistry, pharma, finance and AI. The filing also highlights a previously announced Business Combination and an approximately
Horizon Quantum Computing describes how it has built its first in‑house quantum computer in Singapore as a hardware testbed for its Triple Alpha software tools. The company says it invested about $2.6 million in constructing the processor and surrounding test electronics so developers can compile programs from its languages down to a proprietary quantum assembly language and run them both on cloud systems and on Horizon’s own hardware.
Management explains that operating its own system helps deepen local skills across software, hardware integration and operations, and supports team expansion in Singapore and Ireland, though no headcount targets are disclosed. The CEO notes industry expert surveys that place commercially meaningful quantum applications roughly two to four years away, with potential uses in areas like chemistry, pharma, finance and AI.
The communication also references Horizon Quantum’s previously announced business combination with dMY Squared Technology Group via Holdco and an associated PIPE financing of approximately $110 million of Class A ordinary shares, which remain subject to shareholder approvals, regulatory clearances and other closing conditions.
Horizon Quantum discusses its role in quantum computing and its pending merger with dMY Squared Technology Group, a blank-check company. CEO Joe Fitzsimons explains that Horizon builds hardware-agnostic quantum software infrastructure, including the Triple Alpha development environment and the new Beryllium object-oriented language, to let developers program quantum computers more like classical systems and target multiple hardware platforms.
The discussion highlights recent progress in quantum error correction, the diversity of hardware modalities, and Horizon’s AWS-like usage-based business model for cloud access, with on-prem models likened to Windows Server or VMware. The text notes a previously announced business combination among Horizon Quantum, Horizon Quantum Holdings Ltd. and dMY Squared, supported by a registration statement on Form F-4 and a contemplated private placement of approximately $110 million of Holdco Class A ordinary shares, with shareholders to receive a proxy statement/prospectus before voting at a special meeting.
Horizon Quantum Computing and dMY Squared are advancing a previously announced business combination supported by an approximately $110 million PIPE financing for Holdco’s Class A ordinary shares. This communication shares a detailed interview with Horizon’s CEO, who explains the company’s strategy to build a hardware-agnostic quantum software stack that turns emerging quantum devices into practical, programmable computers. Horizon’s Triple Alpha environment and its new object-oriented language, Beryllium, aim to let mainstream developers write quantum programs at higher levels of abstraction while targeting multiple hardware modalities such as superconducting, trapped-ion, photonic, and neutral-atom systems.
The discussion emphasizes that quantum hardware has recently reached key milestones in error correction and scale, but that software remains critical for delivering real-world applications in fields like chemistry, finance, AI, and energy. Horizon outlines a cloud-style, usage-based business model similar to major infrastructure software providers, with long-term potential for high-margin, software-like economics. The filing also highlights extensive risk factors, including the possibility the business combination or PIPE could be terminated, shareholder redemptions, listing uncertainties, technical challenges operating Horizon’s quantum processor, and the many conditions that must be satisfied before the deal can close.
