$UPS delivered a “flat volume, fatter profits” report in the third quarter: consolidated revenue rose 6.7% year over year to $22.9 billion. The growth may look modest, but its drivers merit a closer look. U.S. domestic package volume was nearly flat, with growth driven entirely by a 6.1% increase in revenue per package; international revenue per package climbed even more, up 15.0%, while Supply Chain Solutions revenue grew 18.2%, led mainly by healthcare and freight. On the earnings front, adjusted diluted EPS was $1.69 on a non-GAAP basis, and the company raised its full-year revenue guidance to about $92.6 billion and adjusted free cash flow guidance to about $6.1 billion. In terms of capital and efficiency, the company has completed its “glide-down” of lower-quality Amazon volume, while network automation is lowering unit costs. Premium mix has replaced volume as the profit engine. However, goodwill impairment dragged the Supply Chain Solutions operating margin down to 3.1%, a reminder that the transformation still comes with growing pains. As e-commerce package volumes peak, how long can profits supported by pricing and automation keep growing?
