Non-GAAP Information

This release includes EBITDA and adjusted EBITDA, which are non-GAAP financial measures, for the periods presented. EBITDA is defined as net loss adjusted to exclude interest income, income tax expense and depreciation and amortization. Adjusted EBITDA is defined as net loss adjusted to exclude interest income, income tax expense, depreciation and amortization, litigation settlement costs, net of recoveries, other income/expense, net, and stock-based compensation expense. These non-GAAP measures are not in accordance with, or an alternative for, measures prepared in accordance with generally accepted accounting principles (GAAP) and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles. We believe that these non-GAAP financial measures, when considered together with our financial information prepared in accordance with GAAP, can enhance investors’ and analysts’ ability to meaningfully compare our results from period to period and to our forward-looking guidance, and to identify operating trends in our business. However, non-GAAP information is not superior to financial measures calculated in accordance with GAAP, is presented for supplemental informational purposes only, has limitations as an analytical tool and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. A reconciliation table of the most comparable GAAP financial measure to the non-GAAP financial measures is included at the end of this press release.

A reconciliation of adjusted EBITDA for the fourth quarter of fiscal 2026 to a corresponding GAAP financial guidance measure is not available on a forward-looking basis because the Company does not provide guidance on GAAP net loss and is not able to present the various reconciling cash and non-cash items between GAAP net loss and adjusted EBITDA without unreasonable effort. In particular, stock-based compensation expense is impacted by the Company’s future hiring and retention needs, as well as the future fair market value of its

common stock, all of which is difficult to predict and is subject to change. The actual amount of these expenses during the fourth quarter of fiscal 2026 will have a significant impact on Twist’s future GAAP financial results.
