If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that neither EigenQ nor SVAQ presently knows or that EigenQ and SVAQ currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect EigenQ’s and SVAQ’s expectations, plans or forecasts of future events and views as of the date of this Current Report. EigenQ and SVAQ anticipate that subsequent events and developments will cause EigenQ’s and SVAQ’s assessments to change. However, while EigenQ and SVAQ may elect to update these forward-looking statements at some point in the future, EigenQ and SVAQ specifically disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing EigenQ’s and SVAQ’s assessments as of any date after the date of this Current Report. Accordingly, undue reliance should not be placed upon the forward-looking statements. Item 9.01. Financial Statements and Exhibits. (c) Exhibits.
