Thank you, operator. Thank you all for joining us to discuss Impinj's first quarter 2019 results. On today's call, Chris Diorio, Impinj's Co-Founder and CEO will provide a brief overview of our market opportunity and performance. Eric Brodersen, Impinj's President, COO and Principal Financial Officer, will follow with a detailed review of our first quarter 2019 financial results and second quarter 2019 outlook. We will then open the call for questions. Impinj's CFO Consultant, Linda Breard; and Impinj's Executive Vice President of Sales and Marketing, Jeff Dossett, are also on the call and will join Chris and Eric in the Q&A session. Management's prepared remarks, along with transit financial data are available on the company's website. Before we start, note that we'll make certain statements during this call that are not historical facts, including those regarding our plans, objectives and expected performance. To the extent we make such statements, they are forward-looking within the meaning of the Private Securities Litigation Reform Act of 1995. Any such forward looking statements represent our outlook only as of the date of this conference call. While we believe any forward-looking statements we make are reasonable, our actual results could differ materially because any statements based on current expectations are subject to risks and uncertainties. Please see the Risk Factors section in the annual and quarterly reports we file with the SEC for additional information about these risks. We do not undertake, and expressly disclaims, any obligation to update or alter our forward-looking statements, whether as a result of new information, future events or otherwise except as required by applicable law. During today's call, all financial numbers we discuss, except for revenue, or where we explicitly state otherwise, are non-cash financial measures. Balance sheet and cash flow metrics are on a GAAP basis. Also note that in fourth quarter 2017, Impinj took a $3.2 million accounting reserve related to a one-time product exchange, for which we recognized an equal amount of revenue in first quarter 2018. Please see the exhibit attached to the written version of these remarks on our Investor Relations website for our first quarter 2018 and first quarter 2019 revenue comparisons reflecting non-GAAP adjustments related to this exchange. Before moving to the financial results, I'd like to announce that the company will attend the Oppenheimer Emerging Growth Conference on May 14th in New York City. We hope to see many of you there. I will now turn the call to Chris Diorio, Impinj's Co-Founder and Chief Executive Officer. Chris?
