Symptom
Gross margin improved 12 points while operating expenses grew 18% in absolute terms — the ratio is improving but the cost base is expanding.
Cause
Gross margin and absolute operating expense growth live in separate reports and are rarely placed on the same axis — the dilution mechanism is invisible in standard financial dashboards.
Impact
When revenue growth decelerates the fixed cost floor reasserts — net margin compresses toward zero or below because the improvement was never structural efficiency.
