Management Commentary

“Nortech delivered another quarter of meaningful operational and financial progress, marking our third consecutive period of positive operating and EBITDA results reflecting the positive execution of our strategic restructuring initiatives. The continued improvements we are seeing in gross margins, manufacturing efficiency, and world-class quality metrics reflect the disciplined execution of our long-term strategy and the dedication of our global team,” said President & CEO, Jay D. Miller.

“Our growing customer backlog, combined with the successful transfer of key programs to our optimized facilities, is strengthening the foundation for sustained performance improvement. We are especially proud of the AS9100:D certification achieved at our Monterrey facility - a significant milestone that further enhances our competitiveness in aerospace, and other high-reliability markets. With the closure of our new debt financing last week, and our strong North American and Asian footprint, we believe we are well-positioned to support customers pursuing nearshore manufacturing strategies. I am grateful for the hard work of our employees across the globe, and we remain optimistic about the opportunities ahead as we continue to execute our strategy into 2026,” Miller said.

Forward-Looking Statements

This press release contains forward-looking statements made pursuant to the safe harbor provision of the Private Securities Litigation Reform Act of 1995 including without limitation statements regarding future financial results including increased gross margin, our ability to generate positive EBITDA, increased plant utilization and manufacturing efficiency, growth of our backlog, continuing improvement of quality metrics, success in moving production from on facility to another Company owned facility, nearshoring as a strategic advantage, successful execution of our long-term strategy, our enhanced competitiveness in aerospace, defense, and other high-reliability markets, effects of restructuring and consolidating manufacturing facilities, sustained long-term health and growth, and optimism about customer pipeline. While this release is based on management’s best judgment and current expectations, actual results may differ materially from those expressed or implied and involve a number of risks and uncertainties. Important factors that could cause actual results to differ materially from the forward-looking statements include, without limitation: (1) commodity cost increases coupled with challenges in raising prices and/or customer pressure to reduce prices; (2) supply chain disruptions leading to shortages of critical components; (3) volatility in market conditions which may affect demand for the Company’s products; (4) increased competition and/or reduced demand; (5) changes in the reliability and efficiency of operating facilities or those of third parties; (6) risks related to the availability of labor; (7) the unanticipated loss of any key member of senior management; (8) geopolitical, economic, financial and business conditions including changing tariff environment; (9) the Company’s ability to steadily improve manufacturing output and product quality; (10) the impact of global health epidemics on our customers, employees, manufacturing facilities, suppliers, the capital markets and our financial condition; (11) challenges with customers with respect to moving production from one facility to another Company-owned facility or (12) financing cost increases and continued availability. Some of the above-mentioned factors are described in further detail in the section entitled “Risk Factors” in our annual and quarterly reports, as applicable. You should assume the information appearing in this document is accurate only as of the date hereof, or as otherwise specified, as our business, financial condition, results of operations and prospects may have changed since such date. Except as required by applicable law, including the securities laws of the United States and the rules and regulations of the United States Securities and Exchange Commission, we undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, to reflect actual results or changes in factors or assumptions affecting such forward-looking statements.

Reconciliation of Generally Accepted Accounting Principles (“GAAP”) Measures to Non-GAAP Financial Measure

EBITDA is a non-GAAP financial measure used by management that we believe provides useful information to investors because it reflects ongoing performance excluding certain non-recurring items during comparable periods and facilitates comparisons between peer companies since interest, taxes, depreciation, and amortization can differ greatly between different organizations as a result of differing capital structures and tax strategies. EBITDA is defined as net income (loss) plus interest expense, plus income tax expense plus depreciation expense and amortization expense. EBITDA should be considered in addition to, not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. Adjusted EBITDA reflects the impact of restructuring and non-recurring items. EBITDA and Adjusted EBITDA are not a measurement of our financial performance under GAAP and should not be considered an alternative to net sales or net income (loss), as applicable, or any other performance measures derived in accordance with GAAP and may not be comparable to other similarly titled measures of other businesses. EBITDA and Adjusted EBITDA have limitations as an analytical metric, and you should not consider it in isolation or as a substitute for analysis of our operating results as reported under GAAP.
