Impinj, Inc. (PI) is a leading provider of radio frequency identification (RFID) solutions and a pioneer in the Internet of Things (IoT) space. Founded in 2000 by Caltech professor Carver Mead and his student Chris Diorio, the company has been at the forefront of transforming the way businesses and consumers interact with everyday items through its innovative RAIN RFID technology.
History and Business Overview
Impinj was established with the vision of creating a "Boundless Internet of Things," where every item that enterprises manufacture, transport, and sell, and that people own, use, and recycle, is wirelessly and ubiquitously connected to the cloud. The company's mission is to connect every "thing" and deliver item visibility and improved operational efficiencies across a wide range of industries.
Impinj pioneered the development of the RAIN RFID standard, which enables wireless connectivity for everyday items. In its early years, the company focused on developing its core RAIN RFID technology and building relationships with partners to drive broader RAIN adoption. Impinj spearheaded the development of the RAIN air-interface standard and worked to secure radio spectrum allocation for RAIN technology globally, laying the foundation for its leadership in the RAIN RFID market.
Over time, Impinj expanded its product portfolio beyond RAIN endpoint ICs, adding reader ICs, readers, gateways, and software solutions. This allowed the company to provide a more comprehensive platform for RAIN-based enterprise solutions. Impinj has built a global ecosystem of partners, including original equipment manufacturers (OEMs), original design manufacturers (ODMs), systems integrators, and value-added resellers, to deliver these solutions to end customers.
Throughout its history, Impinj has faced various challenges, including managing inventory supply and demand, navigating the pace of RAIN market adoption, and defending its intellectual property. In 2011, the company encountered a setback when patent litigation filed against end users temporarily impacted RAIN demand. However, Impinj persevered, continued innovating, and ultimately prevailed in its patent litigation battles.
Financial Performance and Key Metrics
Financials
Impinj has demonstrated consistent revenue growth, reporting a 19.2% increase in total revenue from 2023 to 2024, reaching a record $366.1 million. This growth was primarily driven by a 30% year-over-year increase in endpoint IC revenue, which accounted for the majority of the company's total revenue.
For the fiscal year 2024, Impinj reported: - Revenue: $366.09 million - Net Income: $40.84 million - Operating Cash Flow: $128.31 million - Free Cash Flow: $111.20 million
In the most recent quarter (Q4 2024), Impinj reported: - Revenue: $91.57 million, down 4% sequentially but up 30% year-over-year - Net Income: -$2.69 million
The sequential decline in revenue was due to lower endpoint IC shipment volumes, partially offset by higher systems revenue. The year-over-year increase was driven by strong endpoint IC and licensing revenue.
The company's strong financial performance is also reflected in its profitability metrics. In 2024, Impinj reported a gross margin of 54%, a significant improvement from the 51.9% reported in 2023. This increase was largely attributed to the contribution of high-margin licensing revenue.
Furthermore, Impinj's adjusted EBITDA reached a record $65.9 million in 2024, representing an impressive 18% adjusted EBITDA margin. The company's free cash flow generation also reached new heights, with $66.2 million in 2024, excluding the $45 million income from the litigation settlement.
Liquidity
Impinj's financial strength is underpinned by its large and diversified customer base, which includes some of the world's leading enterprises. In 2024, the company's top three customers accounted for 60% of total revenue, reflecting the deep relationships Impinj has established with its key partners.
As of December 31, 2024, Impinj reported: - Debt/Equity ratio: 1.95 - Cash and investments: $164.71 million - Current ratio: 0.99 - Quick ratio: 0.69
Geographic Performance
Impinj generates the majority of its revenue from the Americas (30% in 2024) and Asia Pacific (57% in 2024) regions. The company has a smaller presence in Europe, Middle East and Africa (13% in 2024). China and Hong Kong together accounted for 44% of total revenue in 2024.
Product Segments
Impinj's platform comprises three main product segments: Endpoint ICs, Systems, and Services.
Endpoint ICs
Impinj's Endpoint IC product family consists of miniature radios-on-a-chip that are embedded into or attached to various items to enable wireless connectivity and identification. These endpoint ICs store a unique serialized number to wirelessly identify the item they are attached to. Impinj's partners embed these endpoint ICs into products, packaging, or other items across a wide range of industries, including retail, supply chain and logistics, healthcare, automotive, and more.
Endpoint IC sales represent the majority of Impinj's revenue, comprising $305.92 million, or 83.6% of total revenue, in 2024. The company has seen strong growth in endpoint IC sales volumes, with a 27% compounded annual growth rate from 2010 to 2024. However, the pace of endpoint IC adoption has been uneven across different markets, leading to variability in Impinj's financial performance.
Systems
Impinj's Systems segment includes reader ICs, finished readers and gateways, test and measurement solutions, and supporting software and cloud services. Impinj's reader ICs are used by OEM and ODM partners in their own mobile, handheld, fixed, and gateway reader products. Impinj's finished readers and gateways integrate the company's reader ICs with beamforming antennas and software to provide high-performance, easy-to-deploy solutions for enterprises.
The company's test and measurement solutions, acquired through the Voyantic Oy acquisition in 2023, enable partners to design, manufacture, and test RAIN-based inlays and labels. Systems revenue was $60.17 million, or 16.4% of total revenue, in 2024. Systems revenue can be volatile, as it is often driven by large-scale deployments with enterprise customers.
Services
In addition to its hardware products, Impinj generates a small portion of revenue from software, extended warranties, enhanced maintenance, support services, and non-recurring engineering (NRE) development services. These service offerings are designed to complement Impinj's platform and enable partners and customers to successfully deploy RAIN-based solutions.
Market Opportunities and Growth Drivers
The growth of the IoT market presents a significant opportunity for Impinj. According to industry estimates, the number of IoT connected devices is expected to continue growing at a rapid pace, reaching over 18 billion units by 2025, representing a 13% year-over-year increase.

Gen2X dramatically improves the performance and security of RAIN systems, creating new opportunities for Impinj to expand its footprint and gain market share.
Risks and Challenges
While Impinj has demonstrated strong growth and financial performance, the company is not without its challenges. The global macroeconomic environment, including geopolitical tensions and trade uncertainties, can impact the company's operations and supply chain.
For example, Impinj's revenue is heavily dependent on the Chinese market, which accounted for 44.4% of the company's total revenue in 2024. Geopolitical tensions and potential trade disruptions between the United States and China could pose a significant risk to Impinj's business.
Additionally, the company's reliance on a limited number of large customers, who accounted for 60% of total revenue in 2024, introduces concentration risk. Any changes in these customers' purchasing patterns or business strategies could have a significant impact on Impinj's financial performance.
Impinj's ability to continue its growth trajectory and maintain its market leadership will also depend on its capacity to successfully navigate the complex and rapidly evolving IoT landscape, as well as its ability to develop and introduce new products and solutions that meet the evolving needs of its customers.
Future Outlook and Guidance
For Q1 2025, Impinj expects: - Revenue between $70 million and $73 million - Adjusted EBITDA between $1.1 million and $2.6 million - Non-GAAP net income between $1.7 million and $3.2 million, reflecting non-GAAP fully diluted earnings per share between $0.06 and $0.11
Impinj expects Q1 2025 endpoint IC revenue to decline sequentially, primarily driven by volume as the channel burns through a few weeks of inventory. The company anticipates Q1 2025 gross margin to be the low point for the year, with Q2 product gross margin benefiting from higher M800 mix and lower-cost wafers.
The company is taking a prudent approach due to current market uncertainty, assuming fewer turns at the midpoint of their Q1 2025 revenue guidance. While Impinj sees strong industry tailwinds and a robust enterprise pipeline, they noted that they are in a "bit of a lull" in terms of new large program ramps, especially in the first half of 2025.
