Cogent Communications is a multinational Tier 1 Internet Service Provider (ISP) providing high-speed Internet, Ethernet, and colocation services to corporate and net-centric customers. Founded in 1999 and headquartered in Washington DC, Cogent operated a lean, profitable business until May 2023 when it completed the transformational (and risky) acquisition of T-Mobile's wireline network assets for ~$1 in cash plus debt assumption — one of the most unusual M&A transactions in recent telecom history.

The T-Mobile wireline acquisition (formerly Sprint's wireline network) added ~$350M of revenue but also massive integration costs, stranded assets, and a complex Transition Services Agreement (TSA) where T-Mobile continues running CCOI's acquired network during migration. The TSA is the make-or-break event — successful completion unlocks significant cost savings; failure creates ongoing expense drag.

Critical milestone: TSA expiration in 2025-2026 is the central value catalyst. When the TSA ends, CCOI loses T-Mobile infrastructure support but gains $100-150M/yr of cost savings on its own network operations. However, the migration has faced delays. Dividend was slashed from $1.005/qtr to $0.02/qtr in Q3 2025 — capital is being redirected to fund the network transition. This is the defining near-term risk/opportunity.

⚠️ THIS IS A CRITICAL POSITION REVIEW: Cogent was acquired as an income stock paying ~$3.92/yr in dividends. That dividend no longer exists — cut 98% in November 2025. The position (1,895 shares, avg cost $54.88) is deeply underwater ($23.07 vs $54.88 = -58%). This should be reviewed against the income mandate of the High Yield bucket.

Bull Case — TSA Synergy Unlock: If the T-Mobile network migration completes successfully in 2026, EBITDA could normalize from $169M to $280-300M by 2027, with FCF turning positive. The $62 outlier PT reflects this scenario. Cogent's fiber network has real strategic value — as a Tier 1 IP carrier, it could be an acquisition target. At $23/share, you're buying the synergy option cheaply.

Bear Case — Execution Risk + Debt Burden: $2.66B in debt at 6% costs $160M/yr in interest — already exceeding EBITDA in prior years. If migration delays persist, cash burn continues (~$200M/yr), and the company may need to raise equity (dilutive) or restructure debt. Revenue is declining (-5.8% in FY2025) as T-Mobile migrates off the network. This is essentially a turnaround bet, not an income investment.

Recommendation: Reduce. This position no longer fits the High Yield income mandate (yield <1%). The thesis has fundamentally changed from 'income compounder' to 'turnaround speculation.' Consider trimming position and redeploying to income-generating alternatives. Hold only a small speculative position if conviction exists in TSA delivery.
