Charter (CHTR) Q2 2026 earnings review
Broadband Bleed Accelerates as Margins Crack
Charter's core broadband business is deteriorating faster than expected. Despite management's narrative that mobile convergence and aggressive pricing guarantees ($1,000 savings) would stem the tide, Q2 26 saw internet subscriber losses accelerate to 172,000. Compounding the volume loss, Adjusted EBITDA fell 4.3% YoY—a sharp deceleration from the ~1.5% declines seen in recent quarters—driven by higher mobile device and service costs. The pending Cox acquisition and the promise of a massive CapEx step-down post-2026 remain the pillars of the bull thesis, but current operational realities reflect a company struggling to defend its moat against fixed wireless and fiber competitors.
🐂 Bull Case
Spectrum Mobile added 406,000 lines, re-accelerating from Q1's 368,000. Mobile service revenue surged 18.9% YoY to $1.09B, providing a crucial top-line offset to legacy video and voice declines.
Management reaffirmed the ~$11.4B FY26 CapEx target. Investors are looking past current EBITDA pressure toward the anticipated post-2026 drop in capital intensity, which is expected to unlock massive free cash flow generation.
🐻 Bear Case
Losing 172,000 Internet customers marks a severe deterioration from the ~120,000 range of the last three quarters, indicating competitive pressures from FWA and fiber are intensifying, not stabilizing.
A 4.3% drop in Adjusted EBITDA reflects a business model in transition. As high-margin broadband subs leave and lower-margin mobile device/service revenues grow, overall margin is compressing (40.3% down from 41.4% YoY).
⚖️ Verdict: 🔴
Bearish. The core engine is shrinking faster than before. While mobile momentum is a bright spot, the accelerating internet losses and resulting EBITDA compression severely weaken the bridge to the post-2026 free cash flow promised land.
Key Themes
Broadband Losses Contradict Retention Narrative
Management has consistently claimed that their converged mobile/broadband bundle offers the 'best overall value' and drives structural retention improvements. The Q2 data directly contradicts this: Internet subscriber losses accelerated to 172,000 (vs. 116,000 a year ago and 120,000 last quarter). The 'game of inches' strategy is currently losing ground to market realities.
Margin Compression Taking Hold
Adjusted EBITDA decelerated sharply, falling 4.3% YoY. While programming costs fell due to accounting shifts (streaming apps netted against revenue), 'Other costs of revenue' spiked 11.3% ($186M). This indicates the shift toward mobile device sales and MVNO service costs is acting as a structural drag on margins as high-margin broadband revenues contract.
Macro Environment & Competitive Intensity
The macro backdrop remains hostile for cable incumbents. Low housing move rates continue to stifle the 'top of funnel' gross adds, while fixed wireless access (FWA) and fiber overbuilders aggressively siphon off existing customers. Charter is relying on heavy promotional activity, like the $1,000 savings guarantee, but it has not yet stemmed the bleeding.
Mobile Remains the Primary Growth Pillar
Spectrum Mobile remains the undisputed bright spot, crossing 12.5 million total lines. Mobile Service revenue accelerated to $1.09B (+18.9% YoY). Charter's ability to offload the vast majority of mobile traffic onto its own Wi-Fi/CBRS network continues to support the economics of this rapidly scaling segment.
Subsidized Rural Network Expansion
Charter activated 127,000 subsidized rural passings in Q2, bringing total passings to 58.98M (+2.5% YoY). Within this rural footprint, customer relationships grew by 47,000 in the quarter. This subsidized expansion remains one of the few reliable vectors for organic volume growth.
Cox Acquisition & Integration Synergies
Management continues to frame the pending Cox transaction as transformative. The thesis relies on pushing Spectrum's superior mobile and converged pricing into Cox's low-penetration footprint to drive growth. Previous quarters noted an upward revision of expected Opex synergies to 'at least $800M,' though navigating the migration of higher-ARPU Cox broadband customers carries immense execution risk.
ARPU Under Pressure
Monthly residential revenue per residential customer declined 1.8% YoY to $117.52. While heavily impacted by the $251M accounting reclassification for programmer streaming apps, underlying pricing power is clearly constrained by the need to offer aggressive convergence discounts to combat churn.
Other KPIs
Declined 7.4% ($77M) YoY. Lower Adjusted EBITDA and an unfavorable change in accrued expenses related to capital expenditures outweighed lower cash taxes. Free cash flow generation is the ultimate benchmark for the company's deleveraging and buyback narrative.
Up 12.3% YoY, entirely driven by cyclical political ad spend. Excluding political revenue, advertising sales actually decreased 4.6% YoY, highlighting the underlying weakness in the linear video advertising market.
Flat YoY (-0.1%). Lower line extension spending was offset by higher upgrade/rebuild costs associated with the company's symmetrical network evolution initiative.
Guidance
Stable. The guidance excludes impacts from the pending Cox transaction. This level of spend represents the tail end of Charter's peak investment cycle before a guided multi-year reduction to below $8B by 2028.
Key Questions
Broadband Floor Reassessment
With Internet losses accelerating to 172,000 this quarter, where does management see the true floor for subscriber declines, and at what point does the 'top of funnel' marketing strategy need a fundamental overhaul?
Margin Trough Visibility
Adjusted EBITDA fell 4.3% as lower-margin mobile device/service revenues replaced high-margin broadband. How much further will margins compress before the scale of the MVNO economics offsets the broadband bleed?
Cox Integration Execution Risk
Given the accelerating deterioration in the standalone Charter business, how confident is management in smoothly migrating Cox's higher-ARPU customers without triggering a massive churn event?
