Background: There are 3 US cell tower eREITs: American Tower Corporation (AMT), SBA Communications Corporation (SBAC) and Crown Castle Inc. (CCI). They differ considerably in the composition of their cell portfolios (macro towers vs. small cells), geographic reach (US only vs. worldwide) and diversification across technology sectors (cell towers, data centers, fiber lines).
Rationale: Cell tower eREITs can improve their future growth prospects by focusing on those world regions that are behind in the wireless technology rollout or by branching out into other technology sectors.
Action: Compare the cell portfolios, geographic focus and breadth of technologies of the 3 US cell tower eREITs.
