iSun, Inc., trading under the ticker JSYN, filed its S-1 registration statement with the SEC on November 23, 2015, marking the company's entry into the public markets as a blank check vehicle targeting acquisition opportunities in the technology and services sectors. The filing, carrying accession number 0001615774-15-003413, reflects the early formation stage typical of SPAC structures organized during the mid-2010s wave of blank check company activity. The entity later evolved through a business combination into iSun, Inc., a company focused on solar energy installation and EV charging infrastructure. The SPAC's 2015 IPO year places it among a cohort of smaller blank check vehicles that preceded the broader SPAC boom of 2020 and 2021.
