Forward looking statements by their nature address matters that are, to different degrees, uncertain, and often contain words such as “may,” “could,” “expect,” “intend,” “plan,” “seek,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” or “continue.” These statements involve known and unknown risks and uncertainties that may cause the events we discuss not to occur or to differ significantly from what we expect. More information about factors that could affect Morningstar’s business and financial results are in our filings with the SEC, including our most recent 8-K, 10-K and 10-Q. Morningstar undertakes no obligation to publicly update any forward-looking statements as a result of new information, future events, or otherwise, except as required by law. In addition, this presentation references non-GAAP financial measures including, but not limited to, organic revenue, adjusted EBITDA and free cash flow. These non-GAAP measures may not be comparable to similarly titled measures reported by other companies.
