18. Segments The accounting policies of the segments are the same as those described in Note 1, “Organization and Significant Accounting Policies.” The operating segments do not make sales to each other. Effective May 1, 2024, segment adjusted gross margin is the measure of profitability used by the CODM for purposes of making decisions about allocating resources to the segments and assessing performance. Segment adjusted gross margin is defined as gross margin before intangible amortization expense including amortization of purchase accounting adjustments. Prior period segment information has been revised to align with the new segment measure of profitability. | | | | | | | | | | | | | | | Three Months Ended July 27, 2024 | | | UxS | | LMS | | MW | | Total | Revenue: | | | | | | | | | | | | | Product sales | | $ | 112,301 | | $ | 47,180 | | $ | 23 | | $ | 159,504 | Contract services | | | 7,675 | | | 4,793 | | | 17,511 | | | 29,979 | | | $ | 119,976 | | $ | 51,973 | | $ | 17,534 | | $ | 189,483 | | | | | | | | | | | | | | Segment adjusted gross margin | | $ | 67,252 | | $ | 13,272 | | $ | 4,657 | | $ | 85,181 | | | | | | | | | | | | | | Depreciation and amortization | | $ | 6,901 | | $ | 800 | | $ | 1,151 | | $ | 8,852 |
