Business/Financial Results (Form 8-K)

Fellow Shareholders,

April 30, 2026

We delivered an outstanding first quarter. Platform revenue grew 28% year over year (YoY), driven by strength in Advertising and Subscriptions - two operating segments we have begun breaking out separately to give investors greater visibility into our business. We continued to increase profitability, generating Net Income of $86 million, Adjusted EBITDA of $148 million, up 165% YoY, and an all-time high of Free Cash Flow (TTM). We also repurchased $100 million of shares in Q1, for a total of $250 million since Q3, under our $400 million stock repurchase program. These results affirm our path to sustaining double-digit Platform revenue growth, expanding margins, and growing our north star metric of Free Cash Flow per share.

Roku Q1 2026 Shareholder Letter

Platform

Platform revenue grew 28% YoY to $1.13 billion, with gross margin of 51.6%. The strong performance was driven by meaningful contributions from both Advertising and Subscriptions, demonstrating the increasing diversity of our monetization. The Roku Experience, which includes our Home Screen, content discovery features, and AI-powered recommendations, continues to be a powerful competitive advantage, driving engagement, advertising, and subscriptions across our platform.

Advertising

Advertising revenue grew 27% YoY to $613 million, with gross margin of 60.5%. In particular, video advertising growth on our platform outpaced both the U.S. OTT and digital ad markets1. We believe this outperformance reflects the growing recognition among advertisers that Roku's unique combination of scale, first-party data, and innovative ad technology delivers measurable outcomes that help businesses grow.

As we grow advertising demand and expand our programmatic capabilities, we are increasing fill rate and the share of Roku video impressions purchased through programmatic channels. Ad spend through third-party programmatic partners increased more than 40% YoY, fueled by deepening integrations with major demand-side platforms (DSPs). For example, in March, we announced an expanded integration with DV360 (Google's Display & Video 360 DSP), which enabled enhanced targeting and measurement through Google's Confidential Publisher Match and Campaign Manager 360. This addition to our existing partnerships, including Amazon DSP, The Trade Desk, Yahoo, and FreeWheel, means advertisers can now access Roku's premium ad inventory through virtually every major buying platform.

Roku Ads Manager, our self-service ad platform for performance and SMB2 advertisers, is another way we're diversifying advertising demand and quickly adding net-new advertisers to our platform. The number of advertisers using Ads Manager in Q1 more than doubled YoY. Roku Ads Manager makes it simple to create, launch, and measure TV streaming campaigns. With generative AI reducing the cost and complexity of producing video creative, we see a significant long-term opportunity to target a meaningful share of the approximately $600 billion in annual SMB ad spend3.

Roku Ads Manager helps businesses drive impact. For example, Blu Dot, the modern home furniture designer, manufacturer, and retailer, drove results around its annual sale by leveraging the Roku Ads Manager Shopify Integration to track full-funnel attribution. Blu Dot was able to link CTV ad views directly to purchases made on mobile or desktop devices. It employed a tiered ad strategy to build awareness and urgency around the sale, engage viewers with interactive Action Ads, and convert high-intent site visitors. During an 11-week campaign, Blu Dot achieved an overall ROAS (return on ad spend) of over 2,000%.

We also continue to expand the advertising categories we serve with our high-visibility, high-margin ads that appear throughout the Roku Experience (RX). In Q1, ad spend from non-Media and Entertainment (M&E) brands reached nearly 30% of total RX advertising revenue, an all-time high, reflecting our strategy to diversify RX revenue beyond M&E partners. Marquee Ad Video (MAV) has been a key driver of that diversification. Positioned on our Home Screen, MAV offers broad reach and strong engagement and serves as a centerpiece of larger brand campaigns on our platform. Though MAV is still small as a portion of total Advertising, the number of advertisers deploying MAV doubled YoY and ad spend tripled YoY in Q1, both of which underscore the value our Home Screen delivers for advertisers.

Subscriptions

Our increased focus on Subscriptions drove strong results, with revenue growing 30% YoY to $519 million and gross margin of 41.1%. Excluding Frndly, Subscriptions revenue grew 23% YoY. Q1 was our highest quarter ever for Premium Subscription sign-ups.

We also continued to scale our owned and operated subscription services. We recently expanded the distribution of Howdy™, our premium, ad-free SVOD4 service for just $3/month, with launches as a subscription option on Prime Video and as a standalone mobile app for iOS and Android. We also launched Howdy on our platform in Mexico.

The Howdy mobile app brings on-the-go access to a curated library of fan favorites.

The success of Super Bowl LX and the Milan Cortina 2026 Olympic Winter Games on Roku underscored the power of our platform. Our ability to combine content discovery, seamless sign-up, and targeted advertising delivers outsized value for our streaming service partners, with more than half of Peacock sign-ups on the Roku platform in February originating from RX. We launched Apple TV and Peacock within Premium Subscriptions, in March and April, respectively. With Premium Subscriptions, viewers can access these services through The Roku Channel, enabling them to enjoy a broad variety of great entertainment in a single app. We see a large opportunity to continue growing Premium Subscriptions, as the experience provides ease and

value for both our viewers and our content partners. In the broader SVOD category, which includes Premium Subscriptions and direct-to-consumer app services, Roku was the fastest-growing distributor of third-party billed subscriptions5.

In April, we launched Peacock within Premium Subscriptions on The Roku Channel.

Devices

In April, we achieved a significant milestone: more than 100 million Streaming Households6 worldwide use a device powered by the Roku TV operating system (OS), a testament to the growing role Roku plays as streaming becomes the primary way people watch TV.

Devices revenue was $118 million, down 16% YoY, with gross margin of (16.3)%, driven primarily by lower player unit sales and promotional pricing. As a reminder, our Devices revenue is generated from the sale of our players and Roku-made TVs (designed, made, and sold by Roku). Devices revenue does not include Roku TV models made by our OEM7 licensing partners, which account for the largest portion of our overall unit volume. We remain well-positioned with a diversified portfolio of streaming players, TVs, and projectors. Roku-made TV unit sales grew YoY, powered by the continued ramp of Hiro Roku TVs at Target, successful relaunches at Best Buy, and strength on Amazon.

On the macro front, we are closely monitoring pricing pressure from tightening memory chip supply that is impacting the entire electronics industry. While we expect higher memory costs will weigh on Device margins in the second half of the year, the Roku TV OS requires significantly less dynamic memory (DRAM) and storage memory (Flash) than competing platforms. We believe this widening cost differential will drive more TV OEMs to partner with us. We are actively expanding and diversifying our OEM licensing agreements and expect new partnerships to begin contributing to Roku TV model unit volume in the second half of 2026.

Outlook

For Q2, we anticipate Platform revenue growing approximately 20% YoY and Devices revenue down high-single digits YoY. We expect this to result in Total net revenue of $1.3 billion, up nearly 17% YoY, with Total gross profit of $580 million and Adjusted EBITDA of $170 million.

For the full year, we are raising our outlook. We now expect Platform revenue to grow nearly 21% YoY to $5.0 billion, and Devices revenue of approximately $535 million, for Total net revenue of $5.5 billion. We anticipate Platform gross margin at the high end of our 51% to 52% range and Devices gross margin in the high (20)% range. Despite our expectation for elevated memory costs in the second half, our overall Devices investment across both gross profit and OpEx remains the same as our prior outlook. For OpEx, we continue to expect it to be more heavily weighted in the second half of the year due to the timing of distribution expenses, and we still anticipate mid-single-digit YoY growth for the full year. As a result, we expect Adjusted EBITDA of $675 million, representing margin improvement of approximately 330 basis points YoY.

We are executing against our monetization initiatives and remain well-positioned to drive sustained double-digit Platform growth and achieve $1 billion of Free Cash Flow by 2028, if not sooner.

Happy Streaming™!

Use of Non-GAAP Measures

In addition to financial information prepared in accordance with generally accepted accounting principles in the United States (GAAP), this shareholder letter includes certain non-GAAP financial measures. These non-GAAP measures include Adjusted EBITDA and Free Cash Flow (FCF). In order for our investors to be better able to compare our current results with those of previous periods, we have included a reconciliation of GAAP to non-GAAP financial measures in the tables at the end of this letter. The Adjusted EBITDA reconciliation excludes total other income, net, stock-based compensation expense, depreciation and amortization, restructuring charges, and income tax (benefit) expense from the net income (loss) of the period, and the FCF reconciliation excludes capital expenditures and effects of exchange rates from the cash flow from operations of the period, in each case where applicable. We believe these non-GAAP financial measures are useful as a supplement in evaluating our ongoing operational performance and enhancing an overall understanding of our past financial performance. However, these non-GAAP financial measures have limitations, and should not be considered in isolation or as a substitute for our GAAP financial information.
