Q3 Results Confirm Mixed Progress: Peacock Strength and Wireless Growth Offset Ongoing Broadband Decline

What happened

Comcast's Q3 2026 results showed flat pro forma revenue and a 1% increase in adjusted EBITDA, as continued profitability at Peacock and strong wireless line growth offset persistent weakness in domestic broadband. Connectivity & Platforms revenue declined 2.6%, indicating that broadband monetization remains under pressure despite improved subscriber trends. The results are consistent with the company's strategy of using wireless cross-sell and streaming profitability to compensate for broadband erosion, but they do not yet provide clear evidence that broadband revenue is stabilizing. Management's earlier guidance had called for proof of paid conversion of free wireless lines and a narrowing broadband revenue decline; while wireless growth appears robust, the segment-level decline suggests broadband revenue may still be falling at a meaningful rate. Overall, the quarter reflects incremental progress on the non-broadband pillars but falls short of confirming the thesis that broadband economics are turning.

Implication

Investors should view Q3 as confirmation that the wireless and Peacock pillars are performing, but they do not resolve the primary investment question of whether broadband revenue can stop declining without sacrificing long-term pricing power. The 2.6% decline in Connectivity & Platforms revenue, despite strong wireless adds, implies that broadband revenue is still contracting at a pace that undermines the post-spin connectivity growth story. While the low 7x P/E and double-digit free cash flow provide downside support, the stock is unlikely to re-rate meaningfully until broadband revenue shows consecutive quarters of improving year-over-year trends. The spin-off of NBCUniversal and Sky remains a medium-term catalyst, but its value is contingent on the remaining connectivity business demonstrating durable economics. Therefore, maintaining a WAIT rating is prudent; a more constructive stance requires evidence of broadband revenue stabilization below 3% decline and clear disclosure of paid wireless conversion rates.

Thesis delta

The investment thesis remains unchanged: Comcast needs to prove that broadband stabilization is economic, not promotional. Q3 results show continued strength in wireless and Peacock, which supports the diversification narrative, but the ongoing decline in Connectivity & Platforms revenue indicates broadband pressure persists. Therefore, the WAIT rating is reaffirmed; the next catalyst is evidence of broadband revenue improvement and paid conversion metrics.
