Return on AI: Weekly Digest — September 9, 2026
Seven findings this week span manufacturing, retail, financial services, and enterprise software. Midea used AI to compress air conditioning design cycles enough to beat rivals into European markets. Convenience stores running AI-assisted SKU planning are seeing 2 to 5 percent margin gains, and Westpac cut a data migration that previously took six weeks down to hours using AI agents. On the adoption and returns side, McKinsey finds only 37 percent of firms are seeing any EBIT lift despite wide agent deployment, Forrester finds factory floors are outperforming other settings for agent value, 80 percent of Fortune 500 companies run agentic AI but few have scaled it, and Globant held AI spend growth to 2.2x while growing token usage 6.7x through intelligent routing.
Key Takeaway of the Week
Deployment breadth does not determine financial return. McKinsey's finding that only 37% of firms see EBIT improvement despite widespread agent adoption makes this the defining ROI reality of the week, and it is reinforced by Globant's counter-example: intelligent token routing produced a 6.7x increase in usage while spend rose just 2.2x, proving that architectural discipline, not adoption volume, is what converts AI activity into margin. CFOs and CIOs should now measure AI programs by cost-per-output efficiency and EBIT contribution, and treat any deployment that cannot show that math as unfinished work.
