Comcast (CMCSA) Stock Analysis 2026 × 5.5x PE, $57 Graham Number vs. $29.63, April 23 Earnings

Comcast Corp (NASDAQ: CMCSA) is trading at $29.63 with a trailing P/E of 5.5x — a valuation more typical of distressed retailers than the owner of Xfinity broadband (~32 million subscribers), NBCUniversal (NFL Sunday Night Football, Bravo, CNBC, Peacock), and Universal theme parks. At $108 billion in market capitalization, Comcast is one of the five or six cheapest large-cap stocks in the S&P 500 on an earnings-multiple basis.

With Q1 2026 earnings scheduled for April 23 — five days from now — the central question is whether the 5.5x PE reflects genuine undervaluation or a structural erosion in the cable business that the market has already correctly priced in. Equity Rank's screener assigns an Overall Score of 76.5, Risk Score of 31.7 (Low), and a Combined Margin of Safety of +75.0%, placing Comcast firmly in the high-value zone among large-caps.

CMCSA Quick-Snapshot (April 2026)

Three Business Segments

Comcast operates three core divisions. Understanding each is essential to evaluating the valuation gap.

Cable Communications (Xfinity) — the profit engine. Xfinity broadband is the core asset. With roughly 32 million residential internet subscribers across 39 states, Comcast operates a near-monopoly or duopoly in most of its service territory. Broadband EBITDA margins run approximately 40–45%. Internet-only revenue continues to grow as video subscribers decline. This segment generates the majority of Comcast's free cash flow and is the primary driver of long-term intrinsic value.

NBCUniversal — content and theme parks. NBCU owns NBC broadcast, cable networks (CNBC, MSNBC, Bravo, USA Network, E!), Universal Pictures film studio, Peacock streaming (36M+ paid subscribers), and Universal theme parks (Hollywood, Orlando, and the newly opened Epic Universe in Orlando). Theme parks are growing rapidly. Peacock has scale but remains unprofitable — streaming investment is the primary drag on current EPS. Sports rights (NFL Sunday Night Football, Big Ten Conference, Paris and LA Olympics) represent durable programming moats through 2032.

Sky — European cable and content. Sky operates satellite and streaming pay-TV across the UK, Germany, and Italy (~22 million customer relationships). The 2018 acquisition cost $39 billion — a premium that has faced persistent questions given currency headwinds, fiber overbuilding in the UK, and competitive pressure from Netflix and Disney+. Sky represents the segment with the most strategic uncertainty.

Equity Rank Valuation: 11 Methods

At $29.63, Comcast's valuations span a wide range depending on methodology. The Conservative methods cluster near $33–$57; the multiple-expansion methods project $100+.

EPV of $33.94 is the most conservative anchor. Earnings Power Value normalizes operating income to remove growth assumptions and asks: what is this business worth if it never grows again? At $29.63, Comcast trades only 13% below EPV — meaning even under a zero-growth scenario, the stock appears modestly undervalued. This is the floor.

Graham Number of $57.23 is almost double the current price. Graham's formula (v22.5 — EPS — Book Value Per Share) at $5.39 trailing EPS and book value per share of ~$27 produces $57.23. The 48% margin of safety relative to the Graham Number is among the widest for any $100B+ company in the screener. Graham's formula was designed for asset-intensive businesses; Comcast's cable infrastructure qualifies.

DDM of $39.07 capitalizes the current dividend ($1.24/year annualized, ~4.2% yield at this price) using a dividend discount approach. Comcast has increased its dividend consistently for over a decade. At $39 DCF-implied value, the current yield and dividend growth trajectory justify a price 32% above current.

PE and DCF at $100+ apply Communication Services sector peer multiples (~19x) to trailing EPS. This approach overstates forward intrinsic value because Comcast's EPS is declining from $5.39 trailing to an estimated $3.70 forward — driven primarily by Peacock investment and video subscriber losses. The trailing PE fair value is informative but should be weighted less than the EPV and Graham Number in the current environment.

Combined Margin of Safety: +75.0%. The Equity Rank model blends all 11 methods into a consensus that strips outliers and weights methods by confidence score. The +75% consensus reflects that even the most conservative methods show meaningful undervaluation.

Why Comcast Trades at 5.5x PE

The discount is not accidental. Four structural concerns explain it:

1. Cord-cutting is structural and accelerating. Comcast lost approximately 2.3 million video subscribers in 2024 and continues to lose ~400K–600K per quarter. Linear TV/cable revenue is in permanent secular decline. The market assigns a low multiple to any business losing its largest revenue category, regardless of offsetting broadband strength.

2. Fiber overbuild by AT&T and T-Mobile. AT&T Fiber has passed ~28 million homes, directly overlapping Comcast's highest-ARPU broadband subscribers. T-Mobile's fixed wireless internet now serves 6M+ households at ~$50/month — competing on price against Comcast's ~$85/month service. Broadband net add stagnation or outright losses are the market's primary concern. If Comcast begins losing broadband subscribers at scale, the entire EPV/DCF thesis breaks.

3. Peacock losses suppress EPS. Comcast guided to peak Peacock losses in 2024; streaming investment remains elevated. The delta between trailing EPS ($5.39) and forward EPS ($3.70) is largely explained by streaming content investment, not operational deterioration in the core cable business. If Peacock reaches profitability by 2027–2028, the EPS gap reverses.

4. Sky acquisition premium unrecovered. The $39B Sky acquisition in 2018 has not generated the synergies initially projected. Impairments and FX headwinds have weighed on reported earnings. The book value impact of writing down Sky is factored into P/B of 1.09x — which is historically cheap for a media/cable conglomerate.

Risk Profile: Low Beta, High Debt

Comcast's Risk Score of 31.7 (lower = safer) reflects a business with defensive cash flow characteristics despite the structural headwinds above.

Why the risk score is low:

• Beta 0.79 — Comcast moves less than the S&P 500; defensive in drawdowns
• Gross margin 71.75% — subscription revenue with high incremental margins
• ROE 21.4% — efficient capital deployment relative to book value
• EV/EBITDA 4.2x — deeply discounted; even utility-grade infrastructure typically trades at 7–9x
• Revenue growth +1.2% — not declining at the top line; broadband ARPU growth offsets subscriber pressure

Why the risk score is not zero:

• ~$100 billion in long-term debt from Sky, NBC, and cable infrastructure financing
• Peacock losses constrain near-term FCF allocation
• Fixed wireless and fiber overbuilding represents a multi-year competitive threat
• Any broadband subscriber loss announcement would likely be harshly punished by the market given how central broadband is to the bull thesis

April 23 Earnings Preview: What Matters

Q1 2026 earnings on April 23 will be judged almost entirely on broadband metrics. The consensus expectations:

Broadband net adds/losses: This is the most watched metric. Any positive net add number is bullish; any net loss — even small — would signal that competition has tipped. The market is pricing in approximately flat to slightly negative broadband net adds in 2026.

Peacock subscribers and revenue vs. losses: Investors want to see Peacock approaching breakeven on the path to 2027 profitability. Revenue growth alone is not enough — the loss trajectory matters.

ARPU trends: Average revenue per broadband user. If ARPU continues rising despite flat subscriber counts, it validates Comcast's pricing power narrative.

Theme park update: Epic Universe Orlando opened in May 2025; Q1 2026 is the first full-quarter comparison. Park revenue growth has been the single brightest spot in Comcast's earnings over the past two years.

Buyback pace: Comcast has been repurchasing shares aggressively at these valuations. The pace of buybacks and remaining authorization matter for EPS trajectory.

Equity Rank Screener Profile

Comcast vs. Cable and Telecom Peers

Comcast's 5.5x trailing PE stands out even against other discounted names in Communication Services:

Comcast at 4.2x EV/EBITDA is meaningfully below its cable peer Charter at ~7x. The gap is explained partly by the Sky drag and Peacock losses — but also by a market that has structurally re-rated cable conglomerates toward utility valuations. If Comcast's EV/EBITDA simply mean-reverts to Charter's level, the stock would be in the $50–$60 range.

Calculator Tools: Model Your Own CMCSA

The Graham Number Calculator lets you verify the $57.23 intrinsic value. Enter trailing EPS of $5.39 and book value per share of approximately $27.18 (P/B 1.09x at $29.63 implies BVPS — $29.63 × 1.09 = $27.18) to confirm the $57.23 output. Then stress-test with forward EPS of $3.70 to see how the Graham Number shifts under declining earnings.

The PE Ratio Calculator reveals the market's implied earnings assumption. At $29.63 and a normalized cable sector PE of 15x, the implied EPS would be $1.98 — far below actual trailing EPS of $5.39. This math shows the market is pricing in either a massive earnings decline or that Comcast permanently deserves a 5x multiple. Enter different PE assumptions (8x, 12x, 15x) to see the fair value range.

The DCF Calculator allows you to model Comcast's broadband cash flow durability. Start with $125B revenue at 1% growth, a 22% FCF margin, and a 9% discount rate. Then stress-test by reducing growth to -1% (broadband net loss scenario) and the FCF margin to 18% (Peacock investment persisting) to see how sensitive intrinsic value is to those assumptions.

All scores, margin of safety estimates, and metrics are model-based outputs subject to estimation uncertainty. The trailing P/E of 5.5x is based on GAAP trailing-twelve-month earnings; the forward P/E of 8.01x uses analyst consensus forward estimates that may not materialize. The PE fair value of $102.41 applies Communication Services sector average multiples to trailing EPS and likely overstates intrinsic value given Comcast's structural headwinds, Peacock investment losses, and expected EPS decline from $5.39 (TTM) to approximately $3.70 (forward). The EPV of $33.94 represents the most conservative normalized earnings power estimate and is the recommended floor for valuation purposes. Comcast carries approximately $95–100 billion in long-term debt from its Sky acquisition (2018, $39B), NBCUniversal acquisition (2011, $30B), and cable infrastructure financing; elevated debt limits financial flexibility and amplifies downside risk if broadband revenue contracts materially. Cord-cutting is a structural, irreversible secular trend; linear video subscriber losses are permanent and represent a declining revenue stream that will not recover. Fixed wireless internet (T-Mobile, Verizon) and fiber overbuilding by AT&T Fiber represent permanent competitive pressure on Comcast's core broadband business. Peacock streaming is not yet profitable and continues to require significant content and marketing investment, suppressing near-term EPS below the trailing run-rate. Revenue growth of 1.2% reflects a slow-growth or maturing business; past growth rates are not indicative of future performance. Beta of 0.79 implies below-market volatility historically but does not eliminate downside risk in a broadband subscriber loss scenario. The $39B Sky acquisition has not generated the synergies initially projected and has been a source of earnings drag and impairment risk.
