StoneBridge Acquisition II is a Special Purpose Acquisition Company (SPAC), also called a blank check company, listed on Nasdaq under the ticker "APAC." StoneBridge has no operations or revenues — it raised $57.5M through an IPO in October 2025 at $10 per unit, with proceeds held in a trust account invested in short-term U.S. Treasuries or money market funds. StoneBridge's sole purpose is to identify and merge with a private company, effectively taking it public via StoneBridge's Nasdaq listing. StoneBridge is targeting international businesses in the APAC and EMEA regions across six verticals: Ecommerce, Fintech, SaaS, Renewable Energy, Mining, and IT and IT-Enabled Services. The stated rationale is "valuation arbitrage" — the idea that international private companies may be undervalued relative to what they could achieve by listing on a U.S. exchange. The sponsor acquired founder shares (Class B Ordinary Shares) for a nominal ~$25,000; these convert to Class A shares upon deal close, giving the sponsor a large equity stake in the resulting public company. Public shareholders have the right to redeem shares at approximately $10 plus interest if they dislike the deal or no deal is completed. StoneBridge has until April 1, 2027, to complete an acquisition (extendable to October 1, 2027 via sponsor-funded extension payments of $575K per increment), or it must liquidate and return trust funds to shareholders. As of the filing date, no acquisition target has been identified.
