The Company’s press release contains non-GAAP financial measures. Pursuant to the requirements of Regulation G, the Company has provided reconciliations within the press release of the non-GAAP financial measures to the most directly comparable GAAP financial measures. Disclosure regarding definitions of these measures used by the Company and why the Company’s management believes the measures provide useful information to investors is also included in the press release.

The Company will conduct a conference call to discuss its financial results on Thursday, November 13, 2025, at 5:00 p.m. Eastern Time.

The information under Item 2.02 of this Report, including Exhibit 99.1 attached hereto, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, nor shall it be deemed incorporated by reference into any filing under the Securities Act of 1933, except as shall be expressly set forth by specific reference in such filing.

This report may contain “forward-looking statements” – that is, statements related to future – not past – events, plans, and prospects. In this context, forward-looking statements may address matters such as our expected future business and financial performance, and often contain words such as “guidance,” “prospects,” “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “should,” or “will.” Forward-looking statements by their nature address matters that are, to different degrees, uncertain. Particular uncertainties that could adversely or positively affect the Company's future results include: we may not have sufficient resources to fund our business and may need to issue debt or equity to obtain additional funding; our reliance on a significant portion of our revenues from a limited number of customers and our ability to diversify our customer base; risks relating to operating in a highly competitive industry; risks relating to supply chain challenges; risk related to changes in labor market conditions; risks related to the implementation of a new enterprise resource IT system; risk related to the development of our procurement and reseller services business; risks relating to rapid technological, structural, and competitive changes affecting the industries we serve; risks involved in properly managing complex projects; risks relating to the possible cancellation of customer contracts on short notice; risks relating our ability to continue to implement our strategy, including having sufficient financial resources to carry out that strategy; and other risks and uncertainties disclosed in our filings with the Securities and Exchange Commission, including the Annual Report on Form 10-K for the fiscal year ended December 31, 2024. These uncertainties may cause our actual future results to be materially different than those expressed in our forward-looking statements. We do not undertake to update our forward-looking statements.
