Our calculation of adjusted EBITDA may not be consistent with similarly titled measures of other companies and should be used in conjunction with GAAP measurements. Management believes that the non-GAAP (U.S. Generally Accepted Accounting Principles) information excluding items such as integration, realignment and restructuring charges, transaction costs, executive transition costs and asset impairment charges are useful to understand the Company's fiscal 2026 financial performance and increases comparability. Specifically, Management believes that removing the impact of these items allows for a meaningful comparison of current period operating performance with the operating results of prior periods. Management also believes that such measures are used by those analyzing performance of companies in the staffing industry to compare current performance to prior periods and to assess future performance. These non-GAAP measures may have limitations as analytical tools because they exclude items which can have a material impact on cash flow and earnings per share. As a result, Management considers these measures, along with reported results, when it reviews and evaluates the Company's financial performance. Management believes that these measures provide greater transparency to investors and provide insight into how Management is evaluating the Company's financial performance. Non-GAAP measures should not be considered a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.

Through our ongoing focus on growth and efficiency, we are well prepared to navigate the evolving macroeconomic environment and capitalize when demand rebounds. Second Quarter of 2026 • Revenue – expect year-over-year improvement relative to Q1, with overall revenue decline of 7% to 9%, which includes at least 100 bps of improvement on an underlying basis excluding discrete customer impacts • Adjusted EBITDA margin – expect at least 2.5%, representing approximately 100 bps improvement relative to Q1 and significant reduction in year-over-year decline relative to the past two quarters Second Half of the Year – Assuming no new material impacts, expect relative improvement in year-over-year performance each successive quarter for both revenue and adjusted EBITDA margin resulting in modest year-over-year revenue growth and measurable adjusted EBITDA margin expansion.
