Yes, ESS Tech, Inc. (ticker: GWH), a provider of long-duration iron flow battery energy storage solutions, has not had a standard stock split in the sense of a public market adjustment. However, it is important for investors to distinguish between standard stock splits and the complex share restructuring that often occurs during a company's transition to a public entity via a Special Purpose Acquisition Company (SPAC) merger. In the case of GWH, its market entry was marked by such a SPAC combination, which involves a pre-set conversion ratio for shares. Any significant change in the number of outstanding shares is typically the result of this initial merger structure or subsequent capital raises, rather than a voluntary board-approved stock split intended to manipulate the price per share for retail accessibility.
