Unless otherwise indicated in this presentation, all information in this presentation is as of October 28, 2025. This presentation includes certain non-GAAP financial measures as defined by SEC rules. 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. Some numbers may not foot due to rounding. There are a number of limitations related to the use of these non-GAAP financial measures versus their nearest U.S. 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 our non-GAAP financial measures to the most directly comparable U.S. GAAP financial measures in the Appendix to this presentation. Bloom has not provided a quantitative reconciliation of forward-looking non-GAAP gross margin and non-GAAP operating income measures to the corresponding U.S. GAAP measures without unreasonable efforts due to the uncertainty regarding, and the potential variability of, reconciling items such as stock-based compensation expense. The variability of these items could significantly impact our future U.S. GAAP financial results and we believe that any reconciliation provided would imply a degree of precision that could be confusing or misleading to investors.
