Thank you, Chris, and good afternoon, everyone. I want to start by taking a moment to reflect on 2021. On the surface, it was a fantastic year for Impinj. We delivered record revenue, adjusted EBITDA and bookings, with revenue and profitability significantly exceeding our expectations. We saw strong bookings momentum throughout the year, capped by a record fourth quarter. Below the surface, however, our team wrestled with Covid-19, supply chain challenges and wafer shortfalls, constraining our ability to fully capitalize on record demand. I can only imagine how much stronger 2021 would have been with more supply. Today, more than ever, I am energized by our massive opportunity. And with the strength of our team, I am optimistic we will capitalize on our record backlog when the supply constraints ease. Fourth quarter revenue was $52.6 million, up 16% sequentially compared with $45.2 million in third quarter 2021 and up 44% year-over-year from $36.4 million in fourth quarter 2020. Fourth quarter endpoint IC revenue was $38.4 million, up 20% sequentially compared with $32 million in third quarter 2021 and up 35% year-over-year from $28.5 million in fourth quarter 2020. Quarter-over-quarter endpoint IC revenue growth significantly outpaced typical seasonal declines. Our specialty and industrial product mix proved richer than our original assumptions, driving revenue above our expectations. Looking forward, we expect first quarter 2022 endpoint IC revenue to decline slightly sequentially, driven by a smaller percentage of specialty and industrial ICs. Fourth quarter systems revenue was $14.2 million, up 7% sequentially compared with $13.2 million in third quarter 2021 and up 79% year-over-year from $7.9 million in fourth quarter 2020. Systems revenue exceeded our expectations, due to our contract manufacturer delivering readers earlier than we expected. On a quarter-over-quarter basis, reader IC and gateway revenue increased while reader revenue declined. On a year-over-year basis reader IC, reader and gateway revenue all increased. We expect first quarter 2022 systems revenue to follow seasonal trends, declining slightly sequentially. 2021 revenue was $190.3 million, up 37% year-over-year compared with $138.9 million in 2020. Endpoint IC revenue grew 36% year-over-year, driven by strength in omnichannel fulfillment, new deployments, expansion of existing deployments and Covid-19 recovery. Systems revenue grew 39% year-over-year, driven by loss prevention and broad-based demand for readers and gateways. Fourth quarter gross margin was 58.2%, compared with 53.3% in third quarter 2021 and 50.4% in fourth quarter 2020. The quarter-over-quarter increase was driven by underlying product margins, partially offset by a smaller contribution from sales of fully reserved inventory. The year-over-year increase was driven by underlying product margins and product mix. Beyond the margin-rich industrial and specialty products, the M700 series became our volume runner, providing a gross margin tailwind in the fourth quarter. The fourth quarter 2021 benefit from selling fully reserved inventory was 130 basis points. Full year 2021 gross margin set an annual record at 54.2%, compared with 49.0% in 2020, with the increase due primarily to lower E&O charges, sales of fully reserved inventory and higher underlying product margins. The 2021 benefit from selling fully reserved inventory was 150 basis points. Total fourth quarter operating expense was $25.3 million, compared with $24.4 million in third quarter 2021 and $21.5 million in fourth quarter 2020. Research and development expense was $12.3 million. Sales and marketing expense was $6.8 million. General and administrative expense was $6.2 million. 2021 operating expense totaled $94.1 million, compared with $79.6 million in 2020. Fourth quarter adjusted EBITDA was a profit of $5.3 million, compared with a loss of $400,000 in third quarter 2021 and a loss of $3.1 million in fourth quarter 2020. 2021 adjusted EBITDA was a profit of $9.1 million, compared with a loss of $11.5 million in 2020. Fourth quarter GAAP net loss was $20 million. Fourth quarter non-GAAP net profit was $4.3 million, or $0.16 per share, using a weighted-average diluted share count of 26.8 million shares. 2021 GAAP net loss was $51.3 million. 2021 non-GAAP net profit was $6.4 million, or $0.25 per share, using a weighted-average diluted share count of 25.9 million shares. Turning to the balance sheet, we ended the fourth quarter with cash, cash equivalents and investments of $207.6 million, compared with $113.3 million in third quarter 2021 and $106.1 million in fourth quarter 2020. In fourth quarter 2021, we issued 1.125% convertible notes due November 2027, generating $287.5 million in gross proceeds and $94.2 million in net proceeds after fees and retiring almost 90% of our 2% convertible notes due December 2026. Inventory totaled $22 million, up $3.5 million from the prior quarter, with the increase primarily from systems. Fourth quarter net cash used in operating activities was $3.9 million. Property and equipment purchases totaled $2.1 million. Free cash flow was negative $6 million. For the full year, net cash provided by operating activities was $6.5 million. Property and equipment purchases totaled $16.2 million. Free cash flow was negative $9.8 million. Before I turn to our first quarter guidance, I want to highlight items unique to fourth quarter and give an update on a few of our strategic initiatives. First, a margin-rich mix of industrial and specialty endpoint ICs, combined with the benefit from selling fully reserved inventory and M700 volume nearly doubling, drove our record fourth quarter gross margin. We expect a slightly less favorable mix of industrial and specialty endpoint ICs in first quarter, driving margins down sequentially. In second quarter 2022, we expect that mix to normalize. Second, back in 2019, to conserve cash, we pivoted our incentive compensation to 100% stock. Since then, we strengthened our balance sheet and, in 2021, delivered record adjusted EBITDA. In 2022, we will pivot our incentive compensation back to a mix of cash and stock. We have reflected the increase in operating expense in our first quarter 2022 guidance. Third, we delivered business-model leverage in an environment where revenue was supply constrained, setting adjusted EBITDA records in fourth quarter and full year 2021. Even as we continue investing in our business in 2022, we remain focused on delivering adjusted EBITDA breakeven or better. Finally, we expect first and second quarter revenue to be supply constrained, with those constraints likely continuing throughout 2022. From today’s vantage point, demand far outstrips our supply. Turning to our outlook, we expect first quarter revenue to be between $50 million and $52 million, a 13% year-over-year increase at the midpoint of the range compared with $45.2 million in first quarter 2021. We expect an adjusted EBITDA profit between $100,000 and $1.6 million. On the bottom line, we expect non-GAAP net income between a loss of $1.1 million and profit of $400,000, reflecting non-GAAP earnings per share between a loss of $0.05 and a profit of $0.01 on a weighted-average diluted share count between 24.9 million and 27.2 million shares. In closing, I want to thank our Impinj team, our customers, our suppliers and you, our investors, for your ongoing support. I will now turn the call to the operator to open the question-and-answer session. Chuck?
