An earnings call is a teleconference, or webcast, in which a public company discusses the financial results of a reporting period ("earnings guidance"). The name comes from earnings per share (EPS), the bottom line number in the income statement divided by the number of shares outstanding. The US-based National Investor Relations Institute (NIRI) says that 92% of companies represented by their members conduct earnings calls and that virtually all of these are webcast. Transcripts of calls may be made available either by the company or a third party.
