ILLINOIS BELL TELEPHONE CO
The historic Illinois Bell Telephone Co. remains rooted in the telecommunications heritage of the 4813/4812 SIC universe, supplying local and long-distance voice services plus legacy infrastructure maintenance to municipalities, small businesses, and legacy enterprise customers across its once vast Midwestern footprint; while today the company’s precise modern offerings are shrouded in limited disclosures, it still must manage regulatory oversight from the FCC and state utility commissions charged with ensuring reliable dial-tone, emergency access, and fair intercarrier compensation even as capital-intensive upgrades to fiber and IP networks raise cost pressures, and its dependency on aging copper plant heightens vulnerability to physical degradation, storm outages, and evolving cybersecurity mandates. Material risk also stems from the cyclical nature of regulated tariffs and the need to comply with the extensive record-keeping and disclosure expectations of the SEC, especially since the latest filing remains unpublished; CIK 49789 positions the firm within these oversight frameworks, so view live SEC filings on Earnings Feed to track updates.
