Blank Check Company
A blank check company is a development stage company that has no specific business plan or purpose or has indicated its business plan is to engage in a merger or acquisition with an unidentified company or companies, other entity, or person. These very small companies typically involve speculative investments and often fall within the SEC’s definition of "penny stocks" or are considered "microcap stocks."
Because of the nature of blank check companies, the SEC does not allow them to use some of the exemptions from the registration requirements when selling their securities. For more information about these exemptions, read our brochure, Q&A: Small Business & the SEC.
