Here's What Key Metrics Tell Us About Comcast (CMCSA) Q3 Earnings

Comcast (CMCSA) posted a split quarter: an EPS beat alongside a revenue decline that landed just under consensus.

The company reported Q3 2026 revenue of $29.3 billion, down 6.1% year-over-year and slightly below consensus estimates. Earnings per share came in at $1.07 against a $0.98 estimate, a beat of $0.09, or roughly 9%.

The underlying metrics tell a weaker story than the headline EPS number. Zacks Investment Research flagged headwinds across wireless line additions, video customer losses, and significant declines in media and video revenues. Zacks assigned CMCSA a Rank #4 (Sell).

Interpretation: a 6.1% revenue contraction paired with an EPS beat suggests the profit upside came from somewhere other than top-line strength. The source does not break out the drivers, so traders should treat the beat as lower quality until the cost and margin picture is clear. The video customer losses and falling media revenues point to pressure in legacy segments, while the wireless line addition shortfall removes one possible offset.

The Zacks Rank #4 signals that estimate revisions are trending negative, which typically weighs on near-term sentiment.
