Exhibit 99.2 INVESTOR PRESENTATION Third Quarter Fiscal 2026 May 6, 2026

FORWARD-LOOKING STATEMENTS This presentation contains forward-looking

statements relating to future events and expectations, including our expectations regarding our estimates and projections for our business outlook for the fourth quarter of fiscal 2026, each of which is based on certain assumptions and

contingencies. The forward-looking statements are made pursuant to the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995 and relate to the Company’s performance on a going-forward basis. The forward-looking

statements in this investor presentation involve risks and uncertainties, which could cause actual results, performance, or trends to differ materially from those described in this presentation. The Company believes that all forward-looking

statements made by it in this presentation have a reasonable basis, but there can be no assurance that management’s expectations, beliefs, or projections as expressed in the forward-looking statements will actually occur or prove to be

correct. In addition to general industry and global economic conditions, factors that could cause actual results to differ materially from those discussed in the forward-looking statements in this presentation include but are not limited to: (i) the

failure of any one or more of the assumptions stated herein to prove to be correct; (ii) changes in demand in the Company’s end markets along with the Company’s ability to respond to such market changes; (iii) our failure to accurately

estimate customer demand and future sales accurately and/or fluctuations in purchasing patterns of customers and end users; (iv) the ability of the Company to retain and hire key employees; (v) the terms of the Company’s indebtedness and

ability to service such debt; (vi) the timely release of new products and acceptance of such new products by the market; (vii) the introduction of new products by competitors and other competitive responses; (viii) the risks to realizing the

benefits of investments in R&D and commercialization of innovations; (ix) the risks that the Company’s stock price will not trade in line with industrial technology leaders; (x) T1the impact of international conflict (such as the current

armed conflict in the Middle East) and economic volatility in either domestic or foreign markets, including T2risks related to the impact of trade protection measures, such as import tariffs by the United States or retaliatory actions taken by other

countries; and/or (xi) the risks relating to forward-looking statements and other “Risk Factors” identified from time to time in our filings with the Securities and Exchange Commission (“SEC”), including our Annual Report on

Form 10-K for the fiscal year ended June 30, 2025, and our subsequently filed Quarterly Reports on Form 10-Q, which filings are available from the SEC. The Company disclaims any obligation to update information contained in these forward-looking

statements, whether as a result of new information, future events or developments, or otherwise. Unless otherwise indicated in this presentation, all information in this presentation is as of May 6, 2026. This presentation contains non-GAAP

financial measures and key metrics relating to the Company’s past performance. We believe the presentation of these non-GAAP financial measures enhances investors' overall understanding of our historical financial performance and assists

investors in comparing our performance across reporting periods. These non-GAAP financial measures are in addition to, and not a substitute for or superior to, measures of financial performance prepared in accordance with U.S. GAAP. There are a

number of limitations related to the use of these non-GAAP financial measures versus their nearest GAAP equivalents. For example, other companies may calculate non-GAAP financial measures differently or may use other measures to evaluate their

performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. As required by Regulation G, we have provided reconciliations of those measures to the most directly comparable GAAP measures in the

section captioned “GAAP to NON-GAAP RECONCILIATION.” The Company has not provided a quantitative reconciliation of forward-looking non-GAAP gross margin percentage, non-GAAP operating expenses, non-GAAP tax rate and non-GAAP earnings per

share, because we cannot, without unreasonable efforts, forecast certain items required to develop comparable GAAP measures. These items include, without limitation, restructuring charges; integration, site consolidation and other expenses; foreign

exchange gains (losses); and share based compensation expense. The variability of these items could significantly impact our future GAAP financial results and we believe that the inclusion of any such reconciliations would imply a degree or

Underlines use the same word lists the scores use. AI, recession and tariffs follow Palanor’s word counter, so those counts match it exactly on the same text. Layoffs and buybacks use the terms the model was given. The model’s count is an estimate by meaning, not by string, so it can differ from the underlines.
