Exhibit 1.01

Roku, Inc.

2025 Conflict Minerals Report

Roku, Inc. (“Roku”) has prepared this Conflict Minerals Report under Rule 13p-1 of the Securities Exchange Act of 1934, as amended. This report covers the period January 1, 2025 to December 31, 2025.

Rule 13p-1 requires disclosure when cassiterite, columbite-tantalite (coltan), gold, and wolframite, and their derivatives, tantalum, tin, and tungsten (“Conflict Minerals”), are “necessary to the functionality or production” of the products that a company manufactures or contracts to manufacture. Rule 13p-1 relates to the sourcing of Conflict Minerals from the Democratic Republic of the Congo, the Republic of the Congo, the Central African Republic, South Sudan, Uganda, Rwanda, Burundi, Tanzania, Zambia, and Angola (the “Covered Countries”).

Conflict Minerals are necessary to the functionality or production of certain Roku products. Roku does not manufacture any products. Instead, Roku contracts with its direct suppliers—contract manufacturers and original design manufacturers—to manufacture or design its products to Roku’s specifications. During 2025, all hardware products that Roku contracted to manufacture contained Conflict Minerals necessary to the functionality or production of those products, including Roku-made TVs, players, remotes, audio equipment, smart home products, and other electronics (collectively, “Covered Products”). This report applies to Covered Products that were manufactured during 2025.

Reasonable Country-of-Origin Inquiry

For 2025, Roku conducted a good-faith reasonable country-of-origin inquiry into which Covered Products incorporate Conflict Minerals. That inquiry was reasonably designed to determine whether any of the Conflict Minerals originated in the Covered Countries or came from recycled or scrap sources. To conduct the inquiry, Roku principally requested its direct suppliers of Covered Products (“Suppliers”) to provide country-of-origin information on the Conflict Minerals used in Covered Products. Based on the information received, Roku has reason to believe that some of the Conflict Minerals contained in the Covered Products may have originated from Covered Countries.

Conflict Minerals Due Diligence Program Design

Roku designed its Conflict Minerals due diligence program to conform, in all material respects, to the Organisation for Economic Co-operation and Development (“OECD”) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas and the related Supplement on Gold and Supplement on Tin, Tantalum and Tungsten, consistent with Roku’s position as a downstream company.

OECD Guidance Step 1: Maintain Strong Company Management Systems

•Roku has adopted a written policy statement on Conflict Minerals, available at https://www.roku.com/investor/governance.

•An internal team with members from Roku’s operations, legal, and finance organizations oversees the Conflict Minerals program.

•The Conflict Minerals team reports its findings to the Chief Accounting Officer and the General Counsel.

•Roku requests that Suppliers report annually on the use of Conflict Minerals in their products using the Conflict Minerals Reporting Template (“CMRT”) published by the Responsible Minerals Initiative (“RMI”).

•Roku maintains a grievance hotline for reporting policy violations.

OECD Guidance Step 2: Identify and Assess Risks in the Supply Chain

•Roku requests that each Supplier submit a completed CMRT.

•Roku follows up with Suppliers on incomplete or inconsistent CMRT submissions.

•Roku attempts to identify high-risk smelters and refiners in its supply chain. Roku compares the smelters and refiners identified by Suppliers as potentially supplying Conflict Minerals for use in the Covered Products against the list of smelters and refiners that are identified as “conformant” or “active” with the RMI’s Responsible Minerals Assurance Process (“RMAP”) assessment protocols and against the list of refiners identified on the current Good Delivery List of the London Bullion Market Association (“LBMA”).

OECD Guidance Step 3: Design and Implement a Strategy to Respond to Identified Risks

•Roku contacts Suppliers that report using smelters or refiners that are not identified by RMAP as “conformant” or “active” or on the LBMA Good Delivery List to confirm whether they have discontinued use of such smelter or refiner.

•Roku asks Suppliers to encourage smelters or refiners that are not conformant with RMAP to participate in the RMAP.

•If Roku determines that a Supplier is sourcing Conflict Minerals that may be financing armed conflict or human rights abuses in the Covered Countries, Roku will determine an appropriate course of action to engage with that Supplier, which may include requesting that the Supplier remove an identified smelter or refiner from its supply chain.

OECD Guidance Step 4: Support the Development and Implementation of Independent Third-Party Audits

•Roku does not have a direct relationship with the smelters and refiners and relies on the independent audits of smelters and refiners that the RMI (and similar organizations) conduct through the RMAP or that are coordinated through the LMBA’s Responsible Sourcing Programme.

OECD Guidance Step 5: Report on Supply Chain Due Diligence

•Roku publishes its Conflict Minerals Report annually, available at https://www.roku.com/investor/sec-filings.

Due Diligence Results

Smelters and Refiners Identified

Roku received a CMRT from each Supplier. Based on the information Suppliers provided for 2025, Roku has reason to believe that some of the Conflict Minerals used in the Covered Products originated from Covered Countries. In certain cases, the information the Suppliers provided was incomplete or unverifiable and may not have included responses from all their suppliers. Further, Roku was unable to determine the country of origin of all the Conflict Minerals needed to manufacture the Covered Products. In addition, some Suppliers provided smelter and refiner information on a company-wide basis, not on a product-specific basis, so some of the smelters or refiners identified may not actually have supplied Conflict Minerals for use in the Covered Products.

The Suppliers identified 209 smelters and refiners, and Roku evaluated each against the RMAP audit and the LBMA Good Delivery List. As of April 1, 2026, of these smelters and refiners, 207 were identified by RMAP as “conformant” and one was considered “active,” or undergoing assessment, for 2025. One smelter was not identified by RMAP as either “conformant” or “active.” Roku asked the relevant Supplier to encourage the smelter to become RMAP-conformant or, if that was not feasible, to transition to an alternative RMAP-conformant smelter. The Supplier then transitioned to an alternative RMAP-conformant smelter.

Below are the results of Roku’s due diligence as of April 1, 2026 on the Conflict Minerals used in Covered Products for 2025, based on the information the Suppliers provided:


	Tin	Tantalum	Tungsten	Gold	Total
Total number of smelters or refiners	53	34	30	92	209
Total number (%) of smelters or refiners identified by RMAP as “Conformant” or “Active”	52 (98%)	34 (100%)	30 (100%)	92 (100%)	208 (>99%)
Total number (%) of “Conformant” smelters or refiners	52 (98%)	34 (100%)	30 (100%)	91 (99%)	207 (>99%)
Total number (%) of “Active” smelters or refiners	0	0	0	1 (1%)	1 (<1%)

The supply chain for the Covered Products is complex. As a downstream purchaser, Roku is many steps removed from the mining and smelting or refining of the Conflict Minerals and does not have direct relationships with smelters and refiners of Conflict Minerals. Roku believes the smelters and refiners are in the best position in the supply chain to determine the origin of the ores, and tracing these minerals to their sources is a challenge that requires Roku to enlist its Suppliers in its efforts to achieve supply chain transparency, including its efforts to obtain information regarding the origin of the Conflict Minerals. The information provided by Suppliers may be inaccurate or incomplete or subject to other irregularities. Because of Roku’s relative location within the supply chain in relation to the actual extraction, transport, smelting, and refinement of Conflict Minerals, Roku’s ability to verify the accuracy of information reported by Suppliers is limited. Roku also relies on third-party organizations to determine the accuracy of representations that upstream producers are “conflict-free,” and is not in a position to independently determine the “conflict-free” nature of Conflict Minerals used in the Covered Products for 2025. Appendix A lists the smelters and refiners that Suppliers reported for 2025.

Efforts to Determine Mine or Location of Origin

Roku requested mine or location-of-origin information from each Supplier to determine the country of origin of the Conflict Minerals in its supply chain. Based on country-of-origin information provided by the Suppliers:

•The Conflict Minerals contained in Covered Products that may have originated from the Covered Countries may have come from the Democratic Republic of the Congo, Rwanda, Tanzania, or Uganda. In some cases, the locations of the mines were unknown and not identified in the CMRT. In other cases, the responses indicated that the minerals were from the Covered Countries but did not identify specific countries.

•The Conflict Minerals contained in Covered Products that may have originated outside the Covered Countries may have come from Australia, Austria, Belgium, Bolivia, Brazil, Canada, Chile, China, Colombia, Czech Republic, Estonia, Germany, India, Indonesia, Italy, Japan, Kazakhstan, Malaysia, Mexico, Netherlands, Peru, Philippines, Poland, Republic of Korea, Singapore, South Africa, Spain, Sweden, Switzerland, Taiwan, Thailand, Turkey, United States, Uzbekistan, or Vietnam.

•Some Conflict Minerals contained in Covered Products may have come from recycled and scrap sources.

•Some Conflict Minerals contained in Covered Products may have originated from the conflict-affected and high-risk areas.

Roku does not have privity of contract with any smelter or refiner listed on Appendix A or control over the origin of the sourcing of any Conflict Minerals processed by any smelter or refiner listed on Appendix A.

The country-of-origin information Suppliers provided was incomplete. Although Roku contacted Suppliers to obtain more complete country-of-origin information, as of the date of this report, Roku has been unable to obtain complete country-of-origin information. As with the list of smelters and refiners, many Supplier responses were provided at the company level, which means this list of countries may include more countries of origin than actual sources of the Conflict Minerals in the Covered Products.

Steps to be Taken to Mitigate Risk

Roku has taken, or intends to take, the following actions to mitigate the risk that the Conflict Minerals in the Covered Products could finance armed groups in the Covered Countries:

•Roku will continue to engage with Suppliers to obtain additional visibility into the sourcing of Conflict Minerals in its supply chain.

•Roku will continue to encourage Suppliers to engage with their upstream smelters and refiners to ensure that they become or remain RMAP-conformant.

•If incidents or allegations arise concerning Conflict Minerals in Roku’s supply chain, Roku will assess and take appropriate responsive action.
