2 Safe Harbor Statement These slides, and the accompanying oral discussion (together, this “presentation”), contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements include, but are not limited to, statements concerning future sales and earnings, which involve known and unknown risks, uncertainties and other factors that could cause the actual results of the Company to differ materially from the results expressed or implied by such statements, including the ability of the Company to complete the acquisition of Dorner, the integration of Dorner into the Company to achieve cost and revenue synergies, the ability of the Company and Dorner to achieve revenue expectations, the ability of the Company to execute its financing plans in connection with the Dorner acquisition, global economic and business conditions including the impact of COVID-19, conditions affecting the industries served by the Company and its subsidiaries, conditions affecting the Company's customers and suppliers, competitor responses to the Company's products and services, the overall market acceptance of such products and services, the ability to expand into new markets and geographic regions, and other factors disclosed in the Company's periodic reports filed with the Securities and Exchange Commission. The Company assumes no obligation to update the forward-looking information contained in this release. Non-GAAP Financial Measures This presentation will discuss some non-GAAP (“adjusted”) financial measures which we believe are useful in evaluating our performance. You should not consider the presentation of this additional information in isolation or as a substitute for results compared in accordance with GAAP. The non-GAAP (“adjusted”) measures are notated, and we have provided reconciliations of comparable GAAP to non-GAAP measures in tables found in the Supplemental Information portion of this presentation. Use of Forward-looking Non-GAAP Financial Metrics This presentation presents forward-looking statements regarding non-GAAP Adjusted EBITDA margin. The Company is unable to present a quantitative reconciliation of these forward-looking non-GAAP financial measures to their most directly comparable forward-looking GAAP financial measures because such information is not available, and management cannot reliably predict the necessary components of such GAAP measures without unreasonable effort or expense. In addition, the Company believes that such reconciliations would imply a degree of precision that would be confusing or misleading to investors. The unavailable information could have a significant impact on the Company’s financial results. These non-GAAP financial measures are preliminary estimates and are subject to risks and uncertainties, including, among others, changes in connection with post-closing adjustments and the factors described above. Any variation between the Company’s actual results and preliminary financial data described in this presentation may be material.

3 Additional Information The Company intends to refinance a portion of the debt to be incurred to finance the Dorner acquisition through an underwritten public offering of shares of its common stock. Any such offering will be subject to market and other conditions, and there can be no assurance as to whether or when the offering may be completed, or as to the actual size or terms of the offering. A shelf registration statement (File No. 333-231827) relating to the Company’s common stock was previously filed with the Securities and Exchange Commission (the “SEC”) and became effective on July 2, 2019. Any offering of shares of the Company’s common stock will be made only by means of a written prospectus and prospectus supplement that form a part of the registration statement. Copies of the preliminary prospectus supplement and accompanying prospectus relating to such offering will be filed with the SEC and, when available, may be obtained by contacting the investment banking firms designated as representatives of the underwriting syndicate for such offering (as to which representatives, additional details will be made available by the Company at a later date). This presentation shall not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of such securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.
