References to “product backlog” means the amount of product sales that have been committed to by customers, but have not yet been completed, shipped, or invoiced. The Company's product backlog can be materially impacted by supply chain constraints, a shift in customer ordering patterns whereby customers place orders in anticipation of extended product delivery lead times, or other customer order delivery request modifications. Furthermore, because the Company partners closely with a number of its customers to produce high-performance, quality components that are often designed into customers’ end products, immediate substitution of the Company’s products is neither typically desired by customers nor necessarily feasible. As such, the Company has not historically experienced significant order cancellations, and the Company does not expect significant order cancellations in the future. The Company closely monitors product backlog and its potential impact on the Company’s financial performance.

References to “EBITDA” mean net loss, before considering interest income and expense, provision for income taxes, depreciation and amortization. References to “Adjusted EBITDA” excludes irregular or non-recurring items and are not directly related to the Company’s core operating performance. EBITDA and Adjusted EBITDA are not measures of financial performance under U.S. GAAP. Management believes EBITDA and Adjusted EBITDA, in addition to operating profit, net income and other U.S. GAAP measures, are useful to investors to evaluate the Company’s results because they exclude certain items that may, or could, have a disproportionate positive or negative impact on our results for any particular period. Investors should recognize that EBITDA and Adjusted EBITDA might not be comparable to similarly-titled measures of other companies. These measures should be considered in addition to, and not as a substitute for or superior to, any measure of performance prepared in accordance with U.S. GAAP. A reconciliation of non-U.S. GAAP EBITDA and Adjusted EBITDA to the most directly comparable U.S. GAAP measure in accordance with SEC Regulation G follows:
