Revenue growth is driven by positive, relatively high elasticities to R&D and SG&A investments, with 1% more R&D boosting revenue by 1.70% and 1% more SG&A boosting revenue by 1.54%, making R&D the more potent driver of topline growth. The log-log model achieves a 6.6% MAPE and held out with a predicted $5.3B versus actual $5.3B, translating to about 1.6% error, indicating credible near-term forecasting performance. With a quarterly revenue of about $5.35B, the FY revenue forecast is $24B, representing a 20.8% year-over-year increase, underpinned by the ongoing revenue responsiveness to spend in R&D and SG&A. The ROI implication is that R&D investment drives stronger revenue uplift than SG&A, supporting a constructive growth outlook while margin outcomes will hinge on the efficiency of SG&A spending and the cost structure as demand evolves.
