This press release and its attachments include certain non-GAAP supplemental performance measures. The presentation of this financial information is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP.

SiTime believes that the presentation of non-GAAP financial measures provides important supplemental information to management and investors regarding financial and business trends relating to SiTime’s financial condition and results of operations. SiTime believes that these non-GAAP financial measures provide additional insight into SiTime’s ongoing performance and core operational activities and has chosen to provide these measures for more consistent and meaningful comparison between periods. These measures should only be used to evaluate SiTime’s results of operations in conjunction with the corresponding GAAP measures. The non-GAAP financial measures exclude stock-based compensation expense, amortization of acquired intangibles, and acquisition-related expenses which include transaction and certain other cash costs associated with business acquisition as well as changes in the estimated fair value of earn out liabilities and accretion of acquisition consideration payable. The reconciliation between GAAP and non-GAAP financial results is provided in the financial statements portion of this release.
