Use of Non-GAAP (Adjusted) Financial Measures

The information provided in this press release includes the non-GAAP financial measures “Adjusted EBITDA” and “Adjusted EBITDA margin” of IXYS. These non-GAAP financial measures exclude the effect of certain expenses and income not related directly to the underlying performance of fundamental business operations and should not be considered in isolation or a substitute for the comparable GAAP measure. A reconciliation of these non-GAAP financial measures to the most directly comparable GAAP measure is included in the appendix of this press release.

Management believes that Adjusted EBITDA and Adjusted EBITDA margin provide useful information to investors regarding operational performance because they enhance an investor’s overall understanding of core financial performance and facilitate comparisons to historical results of operations, by excluding items that are not related directly to the underlying performance of fundamental business operations or were not part of business operations during a comparable period. Management believes that these non-GAAP financial measures are commonly used by financial analysts and others in the industries in which the companies operate, and thus further provide useful information to investors. Management additionally uses these measures when assessing the performance of the business and for business planning purposes. Note that definitions of these non-GAAP financial measures differ from those terms as defined or used by IXYS Corporation and may differ from those terms as defined or used by other companies.
