Crown Castle owns and leases roughly 40,000 cell towers in the United States. It also owns more than 90,000 route miles of fiber. It leases space on its towers to wireless service providers, which install equipment on the towers to support their wireless networks. Crown Castle’s towers and fiber are predominantly in the largest US cities. The company has a very concentrated customer base, with about 75% of its revenue from the Big Three US mobile carriers. Crown Castle operates as a real estate investment trust. It has announced plans to divest its fiber business, which should be finalized in 2026. After that, Crown will be a stand-alone tower operator.
P/FFO (Price to Funds From Operations) is calculated by adding amortization and depreciation to the net income and then deducting the gains on the sale of properties. P/FFO can be quoted as the entire entity's figure in full or on a per-share basis.
In REITs, as the accounting net income is distorted, it ends up being inefficient to use the Earnings per share (EPS), so the FFO is used in the formula instead of the Net Income.
