Revenue is driven primarily by SG&A spending, which the linear model ties to long-run revenue at about $16.20 generated per $1 of SG&A, reflecting strong expense-to-growth leverage observed across 62 quarters of data. The model shows decent but imperfect predictive accuracy, with a holdout forecast of $3.6B vs. $3.9B actual (8% error) and an overall MAPE of 8.2%. For the full year, management guidance implies roughly $15B in revenue, up about 4.2% year over year, indicating steady growth at the current spend efficiency. Outlook: if SG&A-driven leverage remains intact, the revenue path should stay modestly positive, though the lack of visible R&D data adds some uncertainty around other growth drivers and potential upside.
