ITEM 2.02 — RESULTS OF OPERATIONS AND FINANCIAL CONDITION

On February 4, 2026, Crown Castle Inc. ("Company") issued a press release disclosing its financial results for the fourth quarter and full year ended December 31, 2025. A copy of the press release is furnished herewith as Exhibit 99.1.

ITEM 2.05 — COSTS ASSOCIATED WITH EXIT OR DISPOSAL ACTIVITIES

On February 4, 2026, the Company initiated a restructuring plan ("Plan") as part of the Company's efforts to enhance the efficiency and effectiveness of its towers business. The Plan primarily includes reducing the Company's tower and corporate employee headcount recorded in continuing operations (as reported in the Company's consolidated statement of operations) by approximately 20%. In connection with the Plan, the Company estimates it will incur aggregate restructuring charges of approximately $30 million, most of which the Company expects to incur in the first and second quarters of 2026. With respect to the employee headcount reductions, the Company estimates it will incur restructuring charges of approximately $20 million in the first quarter of 2026, substantially all of which would be cash expenditures, consisting primarily of employee severance and other one-time termination benefits. In addition, the Company estimates it will incur up to $10 million in other cash charges related to its headcount realignment actions, such as consolidating office space and downsizing certain information technology license-based contracts. The actions associated with the Plan are expected to be substantially completed by the second quarter of 2026 and payments are expected to be completed by the end of the first quarter of 2027. Charges related to the Plan will be reported in "Restructuring charges" in the Company's consolidated statement of operations. Because of its status as a REIT, the Company does not expect to record any tax benefit associated with the charges recorded in connection with the Plan. The implementation of the Plan and the timing and estimated charges noted above are subject to certain assumptions and risks, including those described below. The Company may incur other charges or cash expenditures not currently contemplated due to unanticipated events that may occur, including in connection with the implementation of the Plan. Should underlying assumptions prove incorrect or risks materialize, actual amounts and timing may differ materially from those expected.
