Forward-Looking Statements

Certain statements in this press release may be considered “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 including, but not limited to, CuriosityStream’s expectations or predictions of future financial or business performance or conditions and the information under the heading “Financial Outlook” in this press release. Forward-looking statements are inherently subject to risks, uncertainties and assumptions. Generally, statements that are not historical facts, including statements concerning possible or assumed future actions, business strategies, events or results of operations, are forward-looking statements. These statements may be preceded by, followed by or include the words “believes,” “estimates,” “expects,” “projects,” “forecasts,” “may,” “will,” “should,” “seeks,” “plans,” “scheduled,” “anticipates,” “predicts” or “intends” or similar expressions. Such forward-looking statements involve risks and uncertainties that may cause actual events, results or performance to differ materially from those indicated by such statements. Certain of these risks are identified and discussed under “Risk Factors” in CuriosityStream’s Annual Report on Form 10-K for the year ended December 31, 2020, filed with the Securities and Exchange Commission (the “SEC”) on March 31, 2021, as amended by the amended Annual Report on Form 10-K/A, filed with the SEC on May 7, 2021, and in CuriosityStream’s other SEC filings. These risk factors will be important to consider in determining future results and should be reviewed in their entirety. Forward-looking statements are based on the current belief of the management of CuriosityStream, based on currently available information, as to the outcome and timing of future events, and involve factors, risks, and uncertainties that may cause actual results in future periods to differ materially from such statements. However, there can be no assurance that the events, results or trends identified in these forward-looking statements will occur or be achieved. Forward-looking statements speak only as of the date they are made, and CuriosityStream is not under any obligation, and expressly disclaims any obligation to update, alter or otherwise revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law. Readers should carefully review the statements set forth in the reports that CuriosityStream has filed or will file from time to time with the SEC.

In addition to factors previously disclosed in CuriosityStream’s reports filed with the SEC and those identified elsewhere in this communication, the following factors, among others, could cause actual results to differ materially from forward-looking statements or historical performance: (i) risks related to CuriosityStream’s limited operating history; (ii) the effects of pending and future legislation; (iii) risks of the internet, online commerce and media industry; (iv) the highly competitive nature of the internet, online commerce and media industry and CuriosityStream’s ability to compete therein; (v) litigation, complaints, and/or adverse publicity; (vi) the ability to meet Nasdaq’s listing standards and (vii) privacy and data protection laws, privacy or data breaches, or the loss of data.

Non-GAAP Financial Measures

To supplement our unaudited condensed consolidated statement of operations, which is prepared in accordance with GAAP, we present EBITDA in this press release. Our use of non-GAAP financial measures has limitations as an analytical tool, and these measures should not be considered in isolation or as a substitute for analysis of financial results as reported under GAAP.

We use this non-GAAP financial measure in conjunction with financial measures prepared in accordance with GAAP for planning purposes, including in the preparation of our annual operating budget, as a measure of our core operating results and the effectiveness of our business strategy, and in evaluating our financial performance. This measure provides consistency and comparability with past financial performance, facilitates period-to-period comparisons of core operating results, and also facilitates comparisons with other peer companies, many of which use similar non-GAAP financial measures to supplement their GAAP results. In addition, EBITDA is widely used by investors and securities analysts to measure a company’s operating performance. We exclude the following items from one or more of our non-GAAP financial measures: other income (expense), income taxes, depreciation and amortization, and loss / (gain) on change in fair value on warrants.

Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool. In particular, (1) although depreciation and amortization expense are non-cash charges, the assets subject to depreciation and amortization may have to be replaced in the future, and EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements, and (2) EBITDA does not reflect: (a) changes in, or cash requirements for, our working capital needs; or (b) tax payments that may represent a reduction in cash available to us. The non-GAAP measure we use may be different from non-GAAP financial measures used by other companies, limiting their usefulness for comparison purposes. We compensate for these limitations by providing specific information regarding the GAAP items excluded from these non-GAAP financial measures. A reconciliation of these non-GAAP measures has been provided in the financial statement tables included in this press release and investors are encouraged to review the reconciliation.
