Comcast’s largest business supplies households with broadband, mobile phone service and television packages, sold separately or in bundles that customers typically pay for monthly. Comcast Business also sells internet access and networks connecting business locations. In the United States, Comcast mainly delivers broadband over its own cable and fiber network; in the United Kingdom and Italy, it relies largely on other operators’ networks and offers services under Sky. Its U.S. residential mobile service uses Verizon’s network alongside Comcast Wi-Fi hotspots, so providing that service depends on its agreement with Verizon.
Comcast also owns television and streaming businesses, including NBC, Telemundo, Sky Sports and Peacock. Advertisers pay to reach their audiences, television providers pay to carry programming, and Peacock customers pay subscription fees directly or through other sellers. Its studios, including Universal Pictures, produce films and television shows and earn mainly by licensing them to networks and streaming services; cinema releases also bring in a share of ticket sales. These businesses depend on attracting audiences and securing programming and sports rights. As viewers move from traditional television to streaming, Comcast loses television subscribers and the associated subscription and distribution revenue.
Universal theme parks in the United States and Asia earn primarily from visitors buying tickets, food and merchandise. This business depends on travel and consumers’ willingness to spend on leisure. Comcast also licenses the Universal Studios brand and other intellectual property to third-party operators.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
Comcast’s content business also depends on major licensing relationships with Warner Bros. and Paramount, neither of which appears in this list.
Charter and Comcast face similar pressures on customer-paid broadband, mobile and TV bundles, mostly in separate service areas, and jointly operate the Xumo streaming platform. Charter’s ability to retain internet customers through mobile bundling offers a comparison for Comcast’s own retention efforts.
Comcast relies on Verizon’s network to serve its U.S. residential mobile customers even as Verizon competes for broadband and mobile subscribers. Verizon’s fiber and home internet delivered over mobile networks are the products to watch for pressure on Comcast’s broadband business.
AT&T competes directly for Comcast’s connectivity customers with expanding fiber broadband, home internet delivered over wireless networks and mobile bundles. Its fiber rollout and combined home-and-mobile offers are worth watching against Comcast’s efforts to retain broadband customers.
T-Mobile US competes for Comcast’s mobile and broadband customers with mobile service and home internet delivered over its wireless network, while that network is scheduled to support Comcast’s business wireless service beginning in 2026. Its 5G home broadband offering is a concrete measure of the alternative facing Comcast’s internet customers.
Walt Disney competes with Comcast for streaming subscriptions, television advertising, cinema audiences and theme-park visitors. Disney’s streaming subscription and advertising revenue provides a comparison for Peacock, while park visitors’ spending matters to Comcast’s Universal parks.
Netflix competes with Comcast’s Peacock and TV packages for viewers’ monthly subscription spending, and with its studios for licensed and original content. Netflix’s membership revenue is a useful comparison for the paid-subscriber growth Comcast seeks at Peacock.
Optimum Communications, Inc. and Comcast face similar subscriber and pricing pressures on broadband, TV and mobile bundles sold to households and businesses over cable and fiber networks. Optimum’s broadband retention and pricing offer a comparison for Comcast as it uses mobile offers to keep internet customers.
Cable One, Inc. and Comcast both depend on retaining household and business internet customers while upgrading their cable broadband networks against competing technologies. Cable One’s internet subscriber trends and rollout of faster service provide a comparison for Comcast’s own network upgrades.
Liberty Global competes with Comcast’s Sky for UK broadband and mobile customers through its half-owned Virgin Media O2. Virgin Media O2’s fiber expansion and broadband-and-mobile offers are the relevant developments to watch, rather than Liberty Global’s other European operations.
Versant Media Group, Inc., spun off from Comcast in January 2026, now competes with Comcast’s remaining TV networks for advertisers’ budgets and the fees providers pay to carry channels. Its network advertising and distribution revenue provides a comparison for the declining linear-TV audience Comcast is trying to offset through Peacock.
Alphabet competes with Comcast on two fronts: YouTube TV seeks subscribers to TV packages, while YouTube seeks advertisers’ budgets alongside Comcast’s television and streaming businesses. YouTube advertising revenue is the line to watch for that advertising rivalry.
EchoStar competes with Comcast for paying TV subscribers through its DISH channel packages, while both face viewers moving to streaming. DISH subscription trends offer a comparison for the customer losses behind Comcast’s expected video revenue decline.
Comcast buys equipment for its cable-access and wireless networks from Vistance Networks, Inc., and accounted for approximately 35% of Vistance’s 2025 net sales. Sales to Comcast are the clearest line to watch for spending on the equipment behind its broadband service.
Space Exploration Technologies competes with Comcast for consumer and enterprise broadband customers through Starlink, which delivers internet by satellite rather than terrestrial networks. Starlink’s coverage, capacity and pricing are the developments to watch for the alternative it offers Comcast customers.
Roku competes with Comcast’s Xumo for streaming households by selling streaming devices and TVs and providing the software that runs connected TVs. Roku’s streaming households and viewing hours indicate the competition Xumo faces for users.
Comcast pays ITG, Inc. to install, engineer and maintain broadband infrastructure, generating 35% of ITG’s 2025 revenue. ITG’s revenue from Comcast provides a direct view of spending on network work and customer installations.
Comcast pays Dycom to build, install and maintain its networks, contributing $413.1 million of Dycom’s fiscal 2026 revenue. Dycom’s Comcast contract revenue is the relevant measure of this network-work relationship, rather than its total sales across other customers.
NetFlix Inc earningsNFLX
Netflix’s paid memberships and membership revenue will show the strength of viewers’ willingness to pay for streaming, a measure of the competition Comcast’s Peacock faces for subscribers.
Read Netflix’s paid membership and membership revenue trends together. Growth in both would show Netflix expanding its paying audience and revenue, intensifying competition for Peacock’s subscribers, content and viewing time; weakness in both would show slower growth at Netflix, not prove that Peacock is growing or declining.
AT&T Inc. earningsT
AT&T’s report will show whether its fiber and wireless home-internet offers are drawing households away from the broadband market Comcast serves.
Watch changes in AT&T’s fiber and wireless home-internet customers alongside growth in those services. Rising customers and stronger business would show that household broadband alternatives are expanding, increasing pressure on Comcast to retain customers; weaker customer or business trends would show less momentum for those offers, not prove Comcast is gaining customers.
Comcast Corp earningsThis company
Comcast’s report will show whether higher rates and wireless growth can support its residential connectivity revenue and profit as broadband customers leave.
Read residential broadband customer changes alongside Residential Connectivity & Platforms revenue and adjusted EBITDA, Comcast’s measure of segment performance, and check whether wireless lines continue to grow. Narrower customer losses with steady revenue and adjusted EBITDA would show that pricing and wireless growth are cushioning the decline; faster losses with weakening revenue or adjusted EBITDA would show the cushion is insufficient and the customer base is eroding.
Alphabet Inc. earningsGOOG
Alphabet’s report will show how YouTube ad revenue is changing, a measure of online video’s competition for Comcast’s TV and streaming advertisers.
Watch the growth in YouTube advertising revenue. Stronger revenue would show online video attracting more advertising spend, intensifying competition for the advertisers and rates that support Comcast’s TV and streaming businesses; weaker revenue would mean slower growth at YouTube, not prove that the spending is moving to Comcast.
Liberty Global Ltd. earningsLBTYA
Liberty Global’s report will show how Virgin Media O2’s fiber expansion and broadband-mobile offers challenge Sky for UK household customers.
Focus on Virgin Media O2’s broadband customer trends and the progress of its fiber expansion and broadband-mobile offers. Customer growth and stronger offers would mean more pressure on Sky to retain UK broadband and mobile users; weak customer or service growth would suggest a less forceful rival, not guarantee that Sky is adding customers.
Versant Media Group, Inc. earningsVSNT
Versant Media Group’s advertising and distribution revenue will show the market for the ad spending and carriage fees that also support Comcast’s remaining TV networks.
Read Versant’s network advertising and distribution revenue together. Stability or growth would show that these linear channels can still attract advertisers and fees from TV distributors; declines in both would suggest that audience losses may keep weakening the advertising and distribution income of Comcast’s remaining networks.
EchoStar Corporation earningsECHO
EchoStar’s DISH subscription trends will show whether households are still leaving paid TV packages, the same shift that pressures Comcast’s video customers and distribution revenue.
Watch changes in DISH subscribers alongside EchoStar’s discussion of its pay-TV business. Faster losses would show households continuing to leave traditional paid TV packages, a similar pressure on Comcast’s video customers and distribution revenue; narrower losses would show slower cancellations at this rival, not prove that Comcast’s video customers have stabilized.
Roku, Inc. earningsROKU
Roku’s streaming households and viewing hours will show how strongly its TV platform attracts users and viewing time, the same audience Comcast’s Xumo seeks.
Read Roku’s streaming households and viewing hours together. Growth in both would show more households using Roku and spending more time on its platform, intensifying Xumo’s competition for connected-TV users and viewing time; weakness in both would show slower momentum at Roku, not prove that users are moving to Xumo.
Vistance Networks, Inc. earningsVISN
Vistance Networks’ sales to Comcast will show whether Comcast is sustaining purchases of equipment for its cable-access and wireless networks.
Watch Vistance’s sales tied to Comcast, not just its total sales. Growth in those sales would show increased Comcast purchases from this network-equipment supplier, consistent with continued network buildout or upgrades; a decline would show reduced purchases from this vendor, but alone would not establish that Comcast is cutting total network investment.
Charter Comm Inc Del earningsCHTR
Charter’s broadband retention and mobile bundles will show whether a cable operator can use mobile service to keep internet customers, a challenge Comcast also faces.
Read Charter’s broadband customer changes alongside mobile growth. Stable broadband customers with a growing mobile business would suggest that bundles can help a cable operator retain households, supporting the logic of Comcast’s approach; continued broadband losses despite mobile growth would show that adding mobile lines may not stop internet customers from leaving.
The Walt Disney Company earningsDIS
Disney’s park attendance and guest spending will show whether visitor demand is supporting the ticket and in-park sales that matter to Comcast’s Universal parks.
Read Disney’s park attendance alongside spending per guest. Stability or growth in both would show that major parks are still drawing visitors who spend, a supportive demand signal for Universal’s tickets, food and merchandise; declines in both would point to weaker attendance or willingness to spend, putting more pressure on those Universal revenues.
ITG, Inc. earningsITG
ITG’s revenue from Comcast will show how much broadband installation, engineering and maintenance work Comcast is sending to this contractor.
Focus on ITG’s revenue from Comcast rather than its entire business. Growth in that revenue would show more broadband engineering, installation or maintenance work flowing to this contractor; a decline would mean less Comcast work for ITG, but would not necessarily mean that Comcast is reducing total network construction or spending.
