At&t Inc. T

AT&T’s FY revenue of $122B fell 3.3% YoY, and our econometric model shows SG&A elasticity of 0.91x, meaning SG&A spend moves revenue nearly proportionally. With the topline shrinking, this suggests SG&A is a near-term growth lever, but it isn’t delivering topline growth on its own—any rebound would likely require favorable pricing/mix or subscriber gains beyond just higher selling/admin spend. The holdout miss—predicted $30.5B vs actual $33.5B, an 8.9% error—highlights modest forecast reliability and potential model misspecification around the latest dynamics. While a 5.9% MAPE is reasonable, the growth-rate risk remains outsized given the telecom’s heavy fixed-cost base and ongoing capex for 5G/fiber, which could amplify margin pressure if revenue doesn’t recover.
