Analysis ROKU
Roku's ads drove 92% of gross profit growth. Why so much?
Higher hardware losses absorbed part of the advertising gain. A planned rise in TV distribution spending will test how much reaches operating profit in Q4.
Roku's advertising and subscription revenue each grew about 23% in the third quarter. Advertising produced much more of the extra gross profit, the revenue left after direct costs.
Research by Ticker Byline shows that advertising supplied about 92% of Roku's $123.6 million increase in total gross profit from a year earlier. Subscription gains also helped, while larger hardware losses absorbed part of the improvement.
Similar sales growth, different margins
Advertising revenue reached $727.4 million. Its gross profit rose to $459.4 million from $345.5 million, as Roku kept a larger share of each advertising dollar. The company attributed that improvement mainly to a shift toward advertising products with higher margins.
Subscriptions generated $580.9 million in revenue and $237.7 million in gross profit, up from $202.3 million. Their margin narrowed, which Roku attributed mainly to the mix of Premium Subscriptions sold through its platform.
The table shows gross profit as a share of revenue for the three months ended September 30.
| Gross margin | 2026 | 2025 |
|---|---|---|
| Advertising | 63.2% | 58.4% |
| Subscriptions | 40.9% | 42.7% |
Hardware took back part of the gain
Device revenue increased to $193.7 million from $146.0 million. Its gross loss widened to $48.6 million from $22.9 million. Roku pointed mainly to higher memory costs.
Roku sells streaming players and televisions to expand the audience it can later earn money from through advertising and subscriptions. Growing hardware sales therefore do not necessarily produce an immediate profit.
Across the company, revenue rose 24% to $1.502 billion and gross profit reached $648.5 million. The overall gross margin slipped to 43.2% from 43.4%, despite advertising's improvement.
The spending test moves into Q4
Roku expects costs to distribute licensed Roku TV models to be weighted toward the fourth quarter. In August, it had already said this spending would be heavier in the second half than in the first.
Those operating expenses come after gross profit. The next question is how much of the stronger advertising margin Roku retains after that spending.
