** Brokerage Wells Fargo upgrades wireless tower operators American Tower AMT.N to "overweight" from "equal weight" and Crown Castle CCI.N to "equal weight" from "underweight"

** Raises PT of AMT to $230 from $210 and CCI to $105 from $85

** Brokerage is increasingly favorable on the tower sector throughout 2025 and heading into 2026, with optimism that carrier activity and domestic billings should improve

** Says steadily improving organic billings as new colocations and leases ramp up, particularly from AT&T T.N, but also selectively with T-Mobile US TMUS.O to help growth for AMT

** Says CCI's fiber and small cell divestiture enables the company to focus solely on the U.S. tower operations and drive long-term growth while increasing its valuation multiples

** Up to last close, AMT stock up 5.9% and CCI stock down 2.8% in the past 12 months
