Middle Coast Investing on Telephone and Data Systems, Inc.

Thesis

TDS is shifting its telecom business from copper into fiber while holding an 82% interest in Array Digital, formerly U.S. Cellular. Array now focuses on cellular towers and has monetized spectrum assets, sending dividends back to TDS. The investor believes this has left a strong balance sheet and reduced the remaining time needed to unlock sum-of-the-parts value, buying shares near $33.

“TDS has a great balance sheet, and two clean business lines.”
