Such statements are based upon current plans, estimates and expectations of management that are subject to various risks and uncertainties that could cause actual results to differ materially from such statements. The inclusion of forward-looking

Ouster&#146;s fourth quarter earnings call all constitute forward-looking statements. All forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially from those that we expected, including,
but not limited to, risks related to the completion of Ouster&#146;s financial closing procedures; Ouster&#146;s ability to recruit and retain key personnel and other important factors discussed in the Company&#146;s Annual Report on Form <FONT
