All Sankey flows are reported GAAP amounts. Product-platform descriptions are qualitative filing context only; Astera does not disclose product-level revenue. Revenue growth, customer concentration, gross margin and R&D intensity come directly from filing tables.
Labels and narrative explain the filing. A category marked “arithmetic bridge” or “residual” is calculated from reported totals, rather than a separately reported line.
