DCF Suggests $300 Value, But Legacy-Plan Migration Risk Warrants Patience

What happened

A recent DCF analysis values T-Mobile at $300 per share, well above the current $168.50, implying significant upside. However, the DeepValue report highlights a critical near-term risk: the mid-July 2026 forced migration of over 8 million legacy-plan customers, which could spike churn and compress cash flow. Q1 2026 postpaid account churn already rose to 1.04% from 0.94% a year ago, and the migration coincides with Verizon's simpler pricing, increasing switching incentives. The base-case valuation of $175 relies on churn remaining near 1.05% and ARPA at $152, but a bear case of $125 is plausible if churn steps up materially. Until Q3 2026 churn data is reported in late October, the stock lacks a clean catalyst for re-rating, making the DCF-based upside contingent on flawless execution.

Implication

The DCF-derived $300 target assumes successful monetization of legacy customers without a churn spike—a premise that the upcoming forced migration will test. Investors should monitor Q3’26 postpaid account churn (target ≤1.10%) and ARPA (≥$152) to validate the thesis. If churn holds, the current valuation offers a compelling entry; if churn rises, the risk of capital impairment is real given leverage of 3.7x net debt/EBITDA. Position sizing should reflect this binary outcome, and only accumulate after the late-October earnings reveal sustained retention.

Thesis delta

The DCF article introduces a bullish valuation anchor that is not reflected in the master report's base case. However, the near-term migration risk overrides that upside until churn data confirms pricing power. No fundamental shift; the WAIT stance remains appropriate.
