ULTRALIFE CORP

Adjusted EBITDA

In evaluating our business, we consider and use adjusted EBITDA, a non-GAAP financial measure, as a supplemental measure of our operating performance in addition to U.S. Generally Accepted Accounting Principles (“GAAP”) financial measures. We define adjusted EBITDA as net income attributable to Ultralife Corporation before net interest expense, provision (benefit) for income taxes, depreciation and amortization, and stock-based compensation expense, plus/minus expense/income that we do not consider reflective of our ongoing continuing operations. We reconcile adjusted EBITDA to net income attributable to Ultralife Corporation, the most comparable financial measure under GAAP. Neither current nor potential investors in our securities should rely on adjusted EBITDA as a substitute for any GAAP measures and we encourage investors to review the following reconciliation of adjusted EBITDA to net income attributable to Ultralife Corporation.
