Parabellum Acquisition Corp. (NYSE: PRBM, PRBMW) operates as a blank check company whose principal business activity is to effect a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or similar business combination with one or more businesses, with a focus on companies possessing proprietary technologies and business models transforming the Internet of Things (IoT) across consumer, industrial, automotive, medical, and other sectors; it does not currently conduct significant operations or generate revenues. The company, founded in 2021 and headquartered in Dallas, Texas, went public in September 2021 with a $125 million initial public offering. As a special purpose acquisition company (SPAC), it targets IoT-related opportunities without specified ongoing products or services beyond its acquisition mandate.
In November 2022, Parabellum entered into a definitive business combination agreement with EnOcean GmbH, a Germany-based leader in energy harvesting wireless IoT sensor technology for smart buildings, valuing the deal at approximately $167 million including up to $146.5 million in gross proceeds; the transaction aimed to take EnOcean public as EnOcean Holdings N.V. Shareholders approved extensions of the business combination deadline multiple times, pushing it to September 30, 2023.
However, in April 2023, EnOcean terminated the agreement due to Parabellum's failure to secure at least $30 million in PIPE financing by February 28, 2023, following high redemptions of 83% leaving only $24.78 million in trust; Parabellum announced the mutual unwind, liquidation of its trust, redemption of all outstanding public shares, and dissolution, with no further pursuit of alternative targets ahead of its May 2023 deadline. Post-termination, the company's common stock trades over-the-counter (OTC: PRBM), and warrants (PRBMW) continue to reflect expired or low-value status as of late 2025. No subsequent mergers, acquisitions, funding rounds, or strategic shifts have been announced, positioning Parabellum as a liquidated SPAC with no active operations.
