Madison Small Cap Fund stated the following regarding Cogent Communications Holdings, Inc. (NASDAQ:CCOI) in its fourth quarter 2025 investor letter:
“We decided to exit our position in Cogent Communications Holdings, Inc. (NASDAQ:CCOI). Our thesis hinged on the company cutting its dividend, a move widely anticipated by the market, and reestablishing growth in EBITDA. These combined moves would have reversed several quarters of increased leverage following the acquisition and integration of assets from T-Mobile. Instead, the company focused on EBITDA and was forced to suspend its dividend temporarily. Although we believe the dividend suspension is the right move, without that valuation ballast, the stock will trade on an uncertain EBITDA multiple. Without this ballast and combined with elevated leverage on the balance sheet, small variations in the multiple can lead to extreme swings in the equity value. We’ve decided to step back and wait until leverage improves.”
