Netflix’s Ad Surge Can’t Mask a Cooling Growth Engine as Analysts Tap the Brakes

Netflix faces a pivotal moment as ad revenue doubles but core subscription growth decelerates, prompting a downgrade from Erste Group amid a 30% stock decline.

Netflix is caught in a tug-of-war between a red-hot advertising business and a core subscription engine that is losing steam. The streaming giant’s shares have taken a hit after a key downgrade, even as its ad revenue is on track to double this year. The tension between these two forces is now the central question for investors.

Erste Group Bank lowered its rating on the stock from Buy to Hold on Monday, triggering a slight dip in the share price on unusually low trading volume. The downgrade comes on the heels of a separate price target cut by Bernstein, which slashed its target to $110 while maintaining a Buy recommendation. Despite the caution, the broader analyst community remains largely bullish, with a consensus price target of roughly $114 and only one sell rating among 38 analysts covering the stock.

The root of the concern lies in Netflix’s latest quarterly report, which signaled a clear deceleration. Management has guided for second-quarter revenue of approximately $12.6 billion, representing 13% growth. That is a notable step down from the 16% expansion recorded in the first quarter, when revenue hit $12.3 billion. For the full year, Erste Group projects top-line growth in the 12% to 15% range, a marked slowdown from the torrid pace of earlier periods.

The stock currently trades around $91.91, more than 30% below its 52-week high and roughly 32% off its all-time peak. Erste Group cited the stock’s “significantly higher” valuation relative to the broader sector as a key reason for the downgrade, arguing that further near-term upside is limited.

Operationally, however, Netflix remains in solid shape. First-quarter operating income climbed 18% to $4.0 billion, while the operating margin improved to 32.3% from 31.7% a year earlier. The company’s full-year margin target of 31.5% remains intact, though management has warned that the current quarter will see peak content costs, which could temporarily compress margins. The second half of the year is expected to bring lower spending.

The real wild card is advertising. Netflix expects ad revenue to hit roughly $3 billion in 2026, doubling from 2025 levels. The number of active advertising partners has surged 70% to over 4,000, and in markets where an ad-supported tier is available, more than 60% of new subscribers now choose the cheaper, ad-funded option. The company is deepening its ties with major platforms such as Amazon, Google, and The Trade Desk to better monetize its growing reach. The Asia-Pacific region is proving to be a particularly strong growth driver.

MoffettNathanson analyst Robert Fishman points to Netflix’s underlying operational strength and sees no signs that the broader economy is hurting its ad business. Still, the advertising segment carries structurally higher margins, and the question is whether it can scale fast enough to compensate for the softening core subscriber dynamics.

All eyes are now on July 16, 2026, when Netflix reports its second-quarter results. That report will test whether the ad business is accelerating quickly enough to justify a premium valuation in a slowing growth environment.
