SIER

Sierra Lake Acquisition Corp

A "blank check" company, or special purpose acquisition company (SPAC), formed to raise money from investors and then merge with or buy an existing business. It went public on the Nasdaq in September 2021 under the ticker SIERU, led by executives with backgrounds in the waste and recycling industry. Like many SPACs of that era, it never found a company to combine with, and it dissolved and returned its money to shareholders in December 2022.
