Prime Number Acquisition I Corp. (PNACR) operates as a blank check company, or special purpose acquisition company (SPAC), focused on effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or similar business combination with one or more businesses. The company targets technology-enabled financial sectors, including blockchain, datacenter infrastructure, non-fungible tokens, ecommerce, and other technology-related infrastructure sectors; it does not engage in significant independent operations prior to completing an initial business combination. Incorporated in 2021 and headquartered at 1129 Northern Blvd., Suite 404, Manhasset, New York, PNACR raised $64.5 million in its initial public offering on May 13, 2022.
In August 2023, PNACR completed a $1.35 billion reverse merger business combination with noco-noco Pte. Ltd., a Singapore-based early-stage decarbonization solutions provider, through which PNACR became a wholly-owned subsidiary of newly formed PubCo, noco-noco Inc. (Nasdaq: NCNC), with noco-noco determined as the accounting acquirer; the combined entity now trades under NCNC and NCNCW tickers following shareholder approval on August 16, 2023, and closing on August 25, 2023. This transaction marked PNACR's primary strategic shift from a pre-combination SPAC to integration within noco-noco's operations, which emphasize battery separator technologies like X-SEPA™ for high heat-resistant performance and a carbon-neutral leasing platform to support global energy transition solutions. No further major acquisitions, funding rounds, or operational changes for PNACR have been reported since the 2023 merger.
