Use of non-GAAP financial measures

Bel Fuse’s earnings releases discuss the use of non-GAAP financial measures such as Non-GAAP net earnings attributable to Bel shareholders, Non-GAAP EPS, Non-GAAP Operating Income and Adjusted EBITDA.

Bel Fuse has also described revisions to its definitions of Adjusted EBITDA and Non-GAAP EPS to exclude stock-based compensation, amortization of intangibles associated with historical acquisitions (including Enercon) and unrealized foreign currency exchange gains or losses.
