Altice USA

Dennis Mathew leads Altice USA, a telecommunications and media company serving 4.4 million customers across 21 states with fiber internet and local news.

Altice USA

Altice USA was formed from the acquisition of Cablevision by the Altice group in 2016. It operates under the Optimum brand following a rebranding initiative. The company is led by Dennis Mathew and serves residential and business customers with internet, TV, phone, and mobile services. The firm invests significant capital into network infrastructure, including the deployment of a new 100% Fiber Internet network capable of symmetrical speeds up to 8 Gig. Asset classes involved include private infrastructure (fiber networks), telecommunications services, and advertising solutions through Optimum Media. The company also operates News 12, a hyper-local news organization providing coverage in the New York tri-state area. Its geographic footprint spans 21 states, with a concentrated presence in the Northeast and mid-Atlantic regions. Altice USA reported approximately 4.4 million customers as of the latest public filings (per company materials, 2025). The company maintains offices in Menlo Park, Palo Alto, New York, Dallas, Seattle, and San Francisco. It supports community initiatives such as DonorsChoose and FIRST Robotics, and has programs to bridge the digital divide. Altice USA operates as a publicly traded cable MSO — distinct from a traditional family office. Its capital deployment is largely driven by infrastructure buildout costs and subscriber acquisition, not external LP capital or fund structures. The company's governance follows a public corporation board model, not a single-family office architecture.
