Quantum Space S-4 Declared Effective Ahead of Planned NYSE Listing

Quantum Space and Inflection Point Acquisition Corp. VI (IPFX ) announced on October 29, 2026 that the U.S. Securities and Exchange Commission has declared effective the Registration Statement on Form S-4 (File No. 333-299286) covering their planned business combination, and that Inflection Point shareholders will vote on the transaction at an extraordinary general meeting on November 20, 2026.

The meeting is scheduled for 10:00 a.m. Eastern Time at the offices of White & Case LLP, 1221 Avenue of the Americas, New York, with participation also available via live webcast. Shareholders of record as of the close of business on October 26, 2026 will vote on proposals to approve the business combination and the other proposals described in the definitive proxy statement/prospectus included in the registration statement, which Inflection Point will mail to shareholders of record.

If the proposals are approved, the business combination is expected to close shortly thereafter, subject to the satisfaction or waiver of all other closing conditions and regulatory review, the companies stated. Upon closing, the combined company will be renamed Quantum Space, Inc. and expects to trade on the NYSE, subject to NYSE approval.

Quantum Space CEO Jim Bridenstine called the milestone “a significant step in Quantum Space’s journey toward becoming a public company.” He said that with approximately US$300 million of committed PIPE financing, the company expects to scale development and production of its Ranger and Scout spacecraft across its facilities in Rockville, Maryland; Hawthorne, California; and Tulsa, Oklahoma.

SEC Filing Record

The SEC’s Notice of Effectiveness records an effectiveness date of October 28, 2026, with the filing accepted at 00:15:18 on October 29, 2026. The notice identifies three co-registrants: IPFX PubCo, Inc. under File No. 333-299286, Quantum Space, LLC under File No. 333-299286-01 and Inflection Point Acquisition Corp. VI under File No. 333-299286-02. The companies’ announcement likewise states that the registration statement was declared effective on October 28, 2026.

SEC filing records for the file number show the registration statement was initially filed on October 5, 2026, amended on October 23 and October 27, 2026, and followed by a 424B3 prospectus filed on October 29, 2026.

Transaction Terms

The parties entered into the business combination agreement on June 8, 2026. The merger announcement issued that day states that Quantum Space has a pre-money equity value of $600 million and an expected post-transaction equity value of approximately $1.2 billion, assuming no redemptions by Inflection Point’s public shareholders. The transaction includes approximately $253 million held in Inflection Point’s trust account, also assuming no redemptions, plus commitments for a convertible PIPE of approximately $300 million at $12 per share, led by Inflection Point Asset Management with participation from additional new institutional investors. Existing Quantum Space equity holders are expected to retain approximately 50% ownership of the pro forma company.

Both companies’ boards of directors unanimously approved the transaction, which the June announcement said was then expected to close in the fourth quarter of 2026. The companies stated that proceeds will fund accelerated production of the Ranger platform and expansion of manufacturing facilities. Cantor is serving as lead placement agent and exclusive financial advisor to Quantum Space, with Moelis & Company (MC ) LLC as joint placement agent. White & Case LLP is serving as legal advisor to Inflection Point, Reed Smith LLP as legal advisor to Quantum Space, and DLA Piper LLP as legal counsel to Cantor and Moelis.

On October 22, 2026, the parties amended the agreement to provide that they intend to list the combined company’s Class A-1 common stock and warrants on the NYSE rather than Nasdaq, according to a Form 8-K filed by Inflection Point on October 23, 2026. The amendment also replaced the agreement’s fixed seven-director post-closing board requirement with a number of directors to be determined by Quantum Space with Inflection Point’s approval, which the filing states is not to be unreasonably withheld, delayed or conditioned, and it made conforming changes to the listing covenant, the NYSE listing condition to closing and the director independence requirement. The June announcement had stated that the combined company expected to be listed on the Nasdaq under the QSPC ticker.

Quantum Space, based in Rockville, Maryland, is developing advanced maneuverable spacecraft for national security, civil and commercial missions. The company was co-founded by Executive Chairman Dr. Kam Ghaffarian and is led by Bridenstine, a former NASA Administrator. According to the company, its flagship Ranger vehicle pairs single-fuel, multi-mode propulsion with a storable fuel capacity of more than 4,000 kilograms, a refuellable and modular architecture and an operational life of up to 15 years, and is being engineered to reach geosynchronous orbit and beyond at up to 70% lower cost than conventional architectures beyond low Earth orbit, based on management estimates and internal analysis. The companies’ risk disclosures state that Ranger is currently in development and has not been manufactured, operated or sold to date.

Quantum Space states that it has six contracts and pending proposals with the U.S. Space Force, the Department of War, DARPA and the Air Force Research Laboratory, and that its management estimates an unweighted pipeline of more than $5 billion across national security, civil and commercial markets. That portfolio includes a contract award under the Space Force’s Andromeda program, an IDIQ vehicle with a $6.2 billion ceiling representing the maximum shared contract value across 14 awardees; the company states it has not yet been allocated any specific funding under the contract. Its operations are anchored by an engineering and mission development facility in Rockville and a propulsion and integration test facility in Hawthorne, with a spacecraft manufacturing center in Tulsa currently in development.

Inflection Point Acquisition Corp. VI is a special purpose acquisition company led by the management team of Inflection Point Asset Management, and the sponsor team’s prior transactions include Intuitive Machines (LUNR ) and USA Rare Earth (USAR ).
