What types of issuers conduct at-the-market offerings? At-the-market offerings recently have become more common, as issuers seek alternative sources of funding. At-the-market offerings are particularly useful for issuers that:
• frequently need to raise additional capital, including REITS, mortgage REITs, biotech companies, and energy and utility companies;
• wish to engage in regular balance sheet maintenance;
• seek to raise small amounts of organic growth capital;
• seek to finance a small acquisition or series of small acquisitions; and
• have insiders that wish to sell registered securities
