## Exhibit 1.01

**Exhibit 1.01**

**Impinj, Inc.**

**Conflict Minerals Report**

**For the Reporting Period from January 1, 2025 to December 31, 2025**

**Part I. Introduction**

This Conflict Minerals Report of Impinj, Inc. for the reporting period January 1, 2025 to December 31, 2025 (the "Reporting Period") has been prepared in accordance with Rule 13p-1 and Form SD promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act").

Rule 13p-1 requires disclosure of certain information when a company manufactures or contracts to manufacture products where the minerals specified in Rule 13p-1 are necessary to the functionality or production of those products. The specified minerals are referred to as "Conflict Minerals," which include columbite-tantalite (coltan), cassiterite, gold, wolframite or their derivatives, which are limited to tantalum, tin and tungsten. The "Covered Countries" for purposes of Rule 13p-1 and this report are the Democratic Republic of Congo, or any adjoining country.

This report and Form SD can be found on our website at investor.impinj.com.

**Part II. Company Overview**

We are a leading provider of RAIN RFID solutions that, together with our partner ecosystem, designs, develops, manufactures and markets RAIN endpoint and reader integrated circuits, reader and gateway products, and test and measurement products ("Covered Products"). We outsource most of our manufacturing of Covered Products to third parties that build to our specifications. We directly manufacture a limited portion of our Covered Products, principally components to some of our test and measurement solutions. We are aware that certain Covered Products contain tin, tantalum, tungsten and gold metals that may be necessary to the functionality or production of those products. We have determined, in good faith, that, for the Reporting Period, the Covered Products require tungsten, tin, tantalum and gold for their production or functionality. To this end, we work with our suppliers to identify the sources of such metals used in the Covered Products. If any of these metals originate from the Covered Countries, then further investigation is required.

We have also adopted a Conflict Minerals Policy and require our suppliers to acknowledge and comply with this policy. If a supplier indicates any noncompliance, we work to quickly investigate and appropriately remediate the matter. Our Conflict Minerals Policy can be found on our website at investor.impinj.com.

**Part III. Reasonable Country of Origin Inquiry** 

We have taken steps to conduct in good faith a reasonable country of origin inquiry ("Inquiry") with respect to the Covered Products that we manufactured or contracted to be manufactured during the Reporting Period. The Inquiry is reasonably designed to determine if any of the Conflict Minerals in the Covered Products originated in the Covered Countries or are from recycled or scrap sources. We have:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•adopted a Conflict Minerals Policy;

oreviewed and evaluated the responses that we received from such suppliers for completeness and accuracy;

oconducted necessary follow-up communications with such suppliers when the information provided appeared to be incomplete and when such suppliers failed to respond within a reasonable period of time;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•evaluated the Covered Products to determine if Conflict Minerals are necessary to the functionality or production of those products; and

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•created processes to (i) determine the country of origin for the Covered Products which were found to contain Conflict Minerals and (ii) identify the use of Conflict Minerals used in new product designs.

We regularly conduct these measures and survey our suppliers using the CMRT for the Covered Products, in addition to newly developed products.

As described in Part IV below, we undertook additional due diligence measures to determine if the Conflict Minerals used in the Covered Products originated in the Covered Countries.

**Part IV. Due Diligence** 

Based on the information provided to us by our suppliers, we undertook additional due diligence processes and efforts based on the RMI in order to determine if any Conflict Minerals included in our Covered Products may have originated in the Covered Countries.

We performed the following due diligence measures:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•established a risk management system to support our ongoing efforts to identify, assess and respond to risks in our supply chain;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•engaged external advisers to assist and consult on our Conflict Minerals due diligence and reporting process;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•surveyed our external suppliers for information concerning whether Conflict Minerals are necessary to the functionality or production of our products and the source and chain of custody of any Conflict Minerals in our supply chain;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•communicated with suppliers, directly or through third-party partners, to determine the source of the Conflict Minerals for the Covered Products; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•monitored, directly or in partnership with third-party providers, the progress of responses, and related follow-up procedures, to internal and external surveys, regarding the use of Conflict Minerals.

**Part V. Due Diligence Results** 

During the Reporting Period, we required our suppliers to perform and report on their supply chain due diligence through the CMRT. For any suppliers that were unresponsive, we performed multiple follow-ups and proactively followed-up via email and/or telephone with such suppliers. We relied on our direct suppliers to provide us with the necessary information about the source of Conflict Minerals contained in the Covered Products that they manufactured for us. Our suppliers similarly relied on their suppliers to provide information regarding the country of origin of Conflict Minerals that were included in the Covered Products. There is a risk that the final information provided to us and upon which we relied was incomplete or inaccurate. Based on the information provided to us by our suppliers, we believe that, to the extent reasonably determinable, the Conflict Minerals necessary for the functionality or production used in the Covered Products were not sourced from Covered Countries.

**Part VI. Risk Mitigation / Future Due Diligence Measures**

We have communicated our expectations to our suppliers regarding our commitment to sourcing minerals for our products in a manner that does not finance or benefit armed groups in the Covered Countries. We plan to continue our Inquiry method to collect and report on conflict minerals due diligence activities. We also continue to work with our suppliers to improve the quality and completeness of information provided by continuing to review our supplier responses and provide feedback as necessary. We encourage our suppliers to remain committed to conflict-free sources and engage with our relevant suppliers in order to build their knowledge and capacity so they are able to provide us with complete and accurate information on the source and chain of custody of Conflict Minerals in our supply chain.
