What Allegro Merger does

Allegro Merger Corp is a Delaware-incorporated Special Purpose Acquisition Company (SPAC) — commonly referred to as a "blank check" company — formed on August 7, 2017 with the sole objective of identifying and acquiring one or more operating businesses through a merger, share exchange, asset acquisition, stock purchase, recapitalization, or similar business combination. The company completed its initial public offering on July 6, 2018, issuing 14,950,000 units (each comprising one common share, a fractional convertible right, and a warrant) and listed on Nasdaq under the ticker "ALGR." Allegro terminated its initial merger agreement with TGI Fridays on March 31, 2020 and subsequently liquidated its trust account, becoming dormant.

The company currently has no commercial products, services, or revenue-generating operations. Its principal activity consists of pursuing and closing a definitive merger agreement announced on January 16, 2026 with SEEQC, Inc., a developer and manufacturer of scalable digital chips for quantum computing systems. Under the transaction structure, SEEQC will form a merger subsidiary that combines with Allegro, leaving Allegro as a wholly-owned subsidiary of SEEQC; the deal is valued at approximately $1 billion enterprise value and includes roughly $65 million of PIPE (Private Investment in Public Equity) financing, with closing expected in Q2 2026 subject to regulatory and shareholder approvals. Cantor and BTIG are lead book-running managers for the concurrent IPO, with Needham & Company and Craig-Hallum acting as co-underwriters.

Allegro maintains a skeleton corporate footprint (1-10 employees) led by CEO David Sgro, domiciled in Manhattan, and operates as an SEC reporting entity with no parent company. Upon closing of the SEEQC transaction, Allegro will cease to exist as an independent public company and SEEQC's business will become the operating entity under a new public listing.

Direct peers

• CF Acquisition Corp. IV: CF Acquisition Corp IV was a SPAC led by Cantor Fitzgerald that merged with Satellogic in 2022. Comparable as a blank-check vehicle pursuing a technology target via de-SPAC, with similar lead underwriter involvement.
• Ace Consolidator Acquisition Corp. Ace Consolidator Acquisition Corp is a small-cap blank-check SPAC that pursued business combinations in similar size ranges. Comparable as a direct peer SPAC with similar shell structure and small-employee footprint to Allegro.
• DPCM Capital, Inc. DPCM Capital was a SPAC that merged with D-Wave Quantum in 2022, providing another quantum-computing public-listing pathway. Directly comparable peer for Allegro given similar quantum SPAC merger mechanic and target company type.
• Churchill Capital Corp IV: Churchill Capital IV was a high-profile SPAC that merged with Lucid Motors in 2021. Comparable as a similarly structured blank-check company executing a de-SPAC merger, though in the EV rather than quantum sector.
• dMY Technology Group, Inc. dMY Technology Group was a SPAC that merged with IonQ in 2021, taking the quantum computing company public at an early commercial stage. It is the most directly comparable peer to Allegro given the matching quantum-computing SPAC structure and similar de-SPAC mechanics.
• Supernova Partners Acquisition Co. II: Supernova Partners II was a SPAC that merged with Rigetti Computing in 2022, another quantum-computing hardware developer going public via the SPAC route. Highly comparable given identical quantum-computing SPAC-merger structure to Allegro's SEEQC transaction.

Emerging players

• SEEQC, Inc. SEEQC is the digital quantum-classical chip developer entering into a definitive merger agreement with Allegro at approximately $1 billion EV. Most directly comparable emerging player as the target absorbing Allegro as a wholly-owned subsidiary.

Broad incumbents

• BTIG, LLC: BTIG is a global financial services firm specializing in institutional trading, investment banking, and SPAC advisory. Comparable as a broad incumbent serving as lead book-running manager for Allegro's pending SEEQC transaction.
• Cantor Fitzgerald, L.P. Cantor Fitzgerald is a global financial services firm that operates as a lead underwriter, market maker, and SPAC sponsor/advisor. Comparable as a broad incumbent in the SPAC and capital markets ecosystem that Allegro relies on for transaction execution.
• Needham & Company, LLC: Needham & Company is an investment bank with deep SPAC and emerging-technology advisory practice. Comparable as a broad incumbent co-underwriting Allegro's SEEQC merger transaction.
