This Amendment No. 1 on Form 10-K/A, or the Amendment, amends Impinj, Inc. ’ s annual report on Form 10-K for the year ended December 31, 2018, originally filed with the Securities and Exchange Commission, or SEC, on February 28, 2019, or the Original Filing. We are amending and refiling Part III to include information required by Items 10, 11, 12, 13 and 14 because our definitive proxy statement will not be filed within 120 days after December 31, 2018, the end of the fiscal year covered by our annual report on Form 10-K.

Pursuant to the rules of the SEC, we have also included as exhibits currently dated certifications required under Section 302 of The Sarbanes-Oxley Act of 2002.

We are amending and refiling Part IV to reflect the inclusion of those certifications, along with any changes to Part IV that occurred after the date of the Original Filing.

In addition, we made certain revisions to the cover page, including the deletion of the reference to our proxy statement and inclusion of updated outstanding share information.

Except as described above, no other changes have been made to the Original Filing. Except as otherwise indicated herein, this Amendment continues to speak as of the date of the Original Filing, and we have not updated the disclosures contained therein to reflect any events that occurred subsequent to the date of the Original Filing.

There are no family relationships among any of the directors or executive officers.

Tom A. Alberg has served as a member of our board of directors since September 2000. Mr. Alberg has been a managing director of Madrona Venture Group, LLC, a venture capital firm, since September 1999, and a principal in Madrona Investment Group, LLC, a private investment firm, since January 1996.

Since 1996, Mr. Alberg has served as a director of Amazon.com, Inc., a publicly traded online retailer. Mr. Alberg received a B.A. in international affairs from Harvard College and a J.D. from Columbia Law School. We believe Mr. Alberg ’ s experience as a venture capitalist investing in technology companies, through which he gained experience with emerging technologies, his experience as a lawyer, and skills relating to financial statement and accounting matters, qualify him to serve as director.

Clinton Bybee has served as a member of our board of directors since January 2008 and chair of our compensation committee since July 2014. He is a managing director of ARCH Venture Partners, a venture capital firm he joined in June 1994.

Previously, Mr. Bybee held various engineering positions with Amoco Corporation. Mr. Bybee received a B.S. in petroleum engineering from Texas A&M University and an M.B.A. from the University of Chicago. We believe that Mr. Bybee ’ s experience as a venture capital investor, including his service on the board of directors of multiple companies, qualifies him to serve as director.

Chris Diorio, Ph.D., one of our co-founders, has served as a member of our board of directors since April 2000, as chief executive officer since November 2014 and as vice chair since September 2013. Previously, he served as our chief strategy and technology officer from September 2013 to November 2014, chief technology officer from November 2006 to September 2013, chair from April 2000 to January 2013, vice president of engineering from 2004 to 2006 and as a consultant to us from April 2000 to June 2004.

We believe Dr. Diorio ’ s perspective, experience and institutional knowledge as our co-founder, vice chair and chief executive officer qualify him to serve as director.

Gregory Sessler has served as a member of our board of directors and as chair of our audit committee since April 2011. Mr. Sessler is the president and chief executive officer and former chief financial officer of Spiration, Inc., a medical device company (acquired by Olympus Corporation of the Americas in 2010), which he joined in 2002.

Graduate School of Business. We believe Mr. Sessler ’ s financial and accounting expertise, in cluding his service as chief financial officer of four publicly-traded companies, qualify him to serve as director and as audit committee chair.

Peter van Oppen has served as our chair and a member of our board of directors since January 2013. Mr. van Oppen has been a partner at Trilogy Partnership, a private investment firm focused on technology and telecommunications, since 2006. Prior to joining Trilogy, Mr. van Oppen served as chair and chief executive officer of Advanced Digital Information Corporation, or ADIC, a publicly-traded storage management software company, from 1994 through its acquisition by Quantum Corp. in 2006.

He is also a former director of Seattle Branch, Federal Reserve Bank of San Francisco. Mr. van Oppen received a B.A. in political science from Whitman College and an M.B.A. from Harvard Business School where he was a Baker Scholar. We believe Mr. van Oppen is qualified to serve as chair because of his experience as a chair and chief executive officer of a global data storage company for over a decade, his extensive management and consulting experience, as well as his experience as a director of other public and private companies.

Theresa Wise has served as a member of our board of directors since May 2016.

Prior to joining Delta, Ms. Wise held a number of positions at Northwest Airlines Corporation, a former publicly traded airline company, including serving as the company ’ s chief information officer from 2001 until Northwest Airlines Corporation ’ s merger with Delta Air Lines in 2008. Ms. Wise received a B.A. in mathematics and chemistry from St. Olaf College and a Ph.D. and M.S. in applied math from Cornell University. We believe Ms. Wise ’ s experience as a senior officer at public companies qualifies her to serve as a director.

Daniel Gibson has served has a member of our board of directors since June 2018. He is a founding partner of Sylebra Capital Management, has been a portfolio manager since June 2011 and chief investment officer since January 2018.

Other than as described herein, there are no arrangements or understandings between Mr. Gibson, on the one hand, and us or any other persons, on the other hand, pursuant to which Mr. Gibson was selected as a director. We believe Mr. Gibson’s financial and investment management expertise as well as extensive experience in the semiconductor and consumer industries qualify him to serve as a director.

CORPORATE GOVERNANCE

Code of Conduct and Ethics

Our board of directors has adopted corporate governance guidelines. These guidelines address, among other items, the responsibilities of our directors, the structure and composition of our board of directors and corporate governance policies and standards applicable to us in general. In addition, our board of directors has adopted a code of business conduct and ethics that applies to all of our employees, officers and directors, including our chief executive officer, chief financial officer, and other executive and senior financial officers. The full text of our corporate governance guidelines and code of business conduct and ethics is posted on the Corporate Governance portion of our website at https://investor.impinj.com/governance. We will post amendments to our code of business conduct and ethics or waivers of our code of business conduct and ethics for directors and executive officers on the same website.

Audit Committee

The members of our audit committee are Messrs. Sessler, Alberg and Bybee, each of whom is a non-employee member of our board of directors. Our audit committee chair, Mr. Sessler, is our audit committee financial expert, as that term is defined under the SEC rules implementing Section 407 of the Sarbanes-Oxley Act of 2002, and possesses financial sophistication, as defined under the rules of The Nasdaq Global Select Market

Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended (the “ Exchange Act ” ). Under the rules of The Nasdaq Global Select Market, a director will only qualify as an “ independent director ” if, in the opinion of that company ’ s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

To be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors or any other board committee: (1) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries or (2) be an affiliated person of the listed company or any of its subsidiaries.

Our board of directors has undertaken a review of its composition, the composition of its committees and the independence of Mr. Sessler and considered whether Mr. Sessler has a material relationship with us that could compromise his ability to exercise independent judgment in carrying out his responsibilities. Based upon information requested from and provided by Mr. Sessler concerning his background, employment and affiliations, including family relationships, our board of directors has determined that Mr. Sessler does not have a relationship that would interfere with the exercise of independent judgment in carrying out his responsibilities and that Mr. Sessler is “ independent ” defined under the rules of The Nasdaq Global Select Market. Our board of directors also determined that Mr. Sessler, who is a member of our audit committee, satisfies the independence standards for such committee established by applicable SEC rules and the rules of The Nasdaq Global Select Market.

In making this determination, our board of directors considered the relationships Mr. Sessler has with us and all other facts and circumstances our board of directors deemed relevant in determining his independence, including his beneficial ownership of our capital stock.

Our audit committee oversees our corporate accounting and financial reporting process and assists our board of directors in monitoring our financial systems. Our audit committee also:


	•		approves the hiring, discharging and compensation of our independent registered public accounting firm;


	•		oversees the work of our independent registered public accounting firm;


	•		approves engagements of the independent registered public accounting firm to render any audit or permissible non-audit services;


	•		reviews the qualifications, independence and performance of the independent registered public accounting firm;


	•		reviews our consolidated financial statements and reviews our critical accounting policies and estimates;


	•		reviews the adequacy and effectiveness of our internal controls; and


	•		reviews and discusses with management and the independent registered public accounting firm the results of our annual audit, our quarterly consolidated financial statements and our publicly filed reports.

Non-Equity Incentive Plan Compensation

2017 Bonus Program and 2018 Bonus Program

Our 2017 Bonus Program and 2018 Bonus Program provide participating executive officers and other members of our management team the opportunity to receive annual formula-based incentive payments for 2017 and 2018 performance, respectively. The payments are based on a target incentive amount for each participating employee.

The 2017 Bonus Program and 2018 Bonus Program provide for incentive compensation based upon our achievement of budgeted bookings goals for 2017 and 2018, respectively. The budget bookings goals include threshold, target and maximum levels of achievement. Between the threshold and target level of achievement, participating employees are eligible to receive a bonus based on a percentage from 0% to 100% of their target incentive amount. Between the target and maximum level of achievement, participating employees are eligible to receive a bonus based on a percentage from 100% and 175% of their target incentive amount. Participating employees must remain employed with us through the date bonuses are paid to receive a bonus under the 2017 Bonus Program or 2018 Bonus Program.

Following the end of 2017, the compensation committee and board of directors reviewed our achievement against the budgeted bookings goals under the 2017 Bonus Program, and determined that our achievement in budgeted bookings for 2017 was below the minimum levels under the 2017 Bonus Program resulting in no bonus payouts.

Following the end of 2018, the compensation committee and board of directors reviewed our achievement against the budgeted bookings goal under the 2018 Bonus Program and determined that approximately 80% of each participating executive’s target incentive amount was earned. The actual bonus payments paid to our named executive officers for achievement under the 2018 Bonus Program are listed in the “Non-Equity Incentive Compensation” column of the Summary Compensation Table above.

Executive Employment Arrangements

Chris Diorio, Ph.D.

This agreement has no specific term and constitutes at-will employment. Effective as of July 3, 2017, Dr. Diorio ’ s annual base salary was increased from $345,000 to $365,000. Effective July 2018, Dr. Diorio became eligible for an annual incentive payment equal to 100% of his base salary, subject to achievement of performance metrics. Dr. Diorio ’ s 2018 bonus opportunity reflects the 85% rate as applied up to July 3, 2018 and the new rate thereafter.

Outside Director Compensation Policy

In connection with our initial public offering in 2016, the board of directors, upon the recommendation of the compensation committee, adopted our outside director compensation policy for the compensation of our outside directors.

The outside director compensation policy was developed in consultation with Compensia, Inc., an independent compensation consulting firm ( “ Compensia ” ). Compensia provided recommendations and competitive outside director compensation data and analyses. Our compensation committee considered and discussed these recommendations and data, and considered the specific duties and committee responsibilities of particular directors. We believe the outside director compensation policy provides our outside directors with reasonable and appropriate compensation that is commensurate with the services they provide and competitive with compensation paid by our peers to their outside directors.

The compensation committee periodically reviews the type and form of compensation paid to our outside directors to ensure the outside director compensation program is competitive and provides compensation that is appropriate for retaining and attracting qualified directors. No changes have been made to our outside director compensation policy since its adoption.

Our outside director compensation policy provides for the following cash compensation to our outside directors:


	•		$25,000 per year for service as a member of the board of directors;


	•		$15,000 per year for service as chair of the board of directors;


	•		$15,000 per year for service as chair of the audit committee;


	•		$10,000 per year for service as chair of the compensation committee;


	•		$5,000 per year for service as chair of the nominating and governance committee; and


	•		$5,000 per year for service as a member of a committee of the board of directors.

- 12 -

Table of Contents

All cash payments to outside directors are paid quarterly in arrears on a pro-rated basis.

This outside director compensation policy provides for the following equity compensation to our outside directors, subject to any limits in our 2016 Equity Incentive Plan, or the 2016 Plan as described in the paragraph below:


	•		on the first day a person becomes an outside director (other than by appointment on the date of each annual meeting of our stockholders), such person will be granted an award of restricted stock units in the amount equal to (1) $60,000 multiplied by a fraction (a) the numerator of which is (x) 12 minus (y) the number of months between the date of the last annual meeting of stockholders and the date the individual became an outside director and (b) the denominator of which is 12; divided by (2) the per share value (as defined below), which is referred to in herein as an initial award;


	•		on the date of each annual meeting of our stockholders, each outside director will be granted an award of restricted stock units in the amount equal to (1) $60,000 divided by (2) the per share value, which is referred to herein as an annual award; and


	•		on the date of each annual meeting of our stockholders, an outside director who is serving as chair of the board of directors and is eligible for an annual award will be granted, in addition to an annual award, an award of restricted stock units in the amount equal to (1) $15,000 divided by (2) the per share value, which is referred to herein as a board-chair annual award, and an outside director who is serving or is appointed as chair of the board of directors and is eligible for an initial award will be granted, in addition to the initial award, a board-chair annual award pro-rated in the same manner as an initial award.

The 2016 Plan provides that in any given year, a non-employee director may not receive awards having a grant date fair value greater than $500,000, as determined under GAAP. This maximum limit does not reflect the intended size of any potential grants or a commitment to make grants in the future.

Each award described in the preceding bullet points, which is referred to herein as an outside director award, vests upon the one year anniversary of the date such award was granted, subject to the director ’ s continuing to be a service provider; however, in the event of a change in control (as defined in the 2016 Plan), all outside director awards shall vest in full.

As used above, per share value generally means the average trading price for a share of our common stock over the ten trading days beginning on the next day following the date we announce fourth quarter earnings for the fiscal year immediately prior to the grant date of an award.

Outside directors may be permitted to defer the delivery of the shares of our common stock subject to an outside director award subject to the terms of our outside director compensation policy.

Outside directors may not sell, pledge, assign, hypothecate, transfer or dispose of in any manner other than by will or by the laws of descent or distribution, shares of our common stock issued pursuant to an outside director award while the outside director continues to serve as a director, other than in order to pay for any tax obligations arising from the vesting and/or settlement of such award.

We also will continue to reimburse our outside directors for reasonable, customary and documented travel expenses incurred in connection with attending board and board-committee meetings.

Compensation Risk

Our compensation programs are designed to balance risk and reward in relation to our overall business strategy. Our management assesses and discusses with our Compensation Committee our compensation policies and practices for our employees as they relate to our risk management, and based upon this assessment, we believe that such policies and practices do not create any risks that are reasonably likely to have a material adverse effect on us in the future.

We have determined beneficial ownership in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, the rules take into account shares of common stock issuable pursuant to the exercise of stock options or warrants that are either immediately exercisable or exercisable on or before the 60th day after March 31, 2019. Certain of the options granted to our named executive officers may be exercised prior to the vesting of the underlying shares. We refer to such options as being “ early exercisable. ” Shares of common stock issued upon early exercise are subject to our right to repurchase such shares until such shares have vested. These shares are deemed to be outstanding and beneficially owned by the person holding those options or a warrant for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the persons or entities identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them, subject to applicable community property laws.

Item 13.	Certain Relationships and Related Transactions, and Director Independence

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

The following is a summary of transactions since January 1, 2018 to which we have been a party in which the amount involved exceeded $120,000 and in which any of our executive officers, directors, promoters or beneficial holders of more than 5% of our capital stock had or will have a direct or indirect material interest, other than compensation arrangements which are described under the section of this filing captioned “ Executive Compensation. ”

Policies and Procedures for Transactions with Related Persons

We have adopted a formal, written policy that our executive officers, directors (including director nominees), holders of more than 5% of any class of our voting securities and any member of the immediate family of or any entities affiliated with any of the foregoing persons, are not permitted to enter into a related party transaction with us without the prior approval or, in the case of pending or ongoing related party transactions, ratification of our audit committee. For purposes of our policy, a related party transaction is a transaction, arrangement or relationship where we were, are or will be involved and in which a related party had, has or will have a direct or indirect material interest.

Certain transactions with related parties, however, are excluded from the definition of a related party transaction including, but not limited to:


	•		transactions involving the purchase or sale of products or services in the ordinary course of business, not exceeding $20,000;


	•		transactions where a related party ’ s interest derives solely from his or her service as a director of another entity that is a party to the transaction;


	•		transactions where a related party ’ s interest derives solely from his or her ownership of less than 10% of the equity interest in another entity that is a party to the transaction; and


	•		transactions where a related party ’ s interest derives solely from his or her ownership of a class of our equity securities and all holders of that class received the same benefit on a pro rata basis.

No member of the audit committee may participate in any review, consideration or approval of any related party transaction where such member or any of his or her immediate family members is the related party. In approving or rejecting the proposed agreement, our audit committee shall consider the relevant facts and circumstances available and deemed relevant to the audit committee, including, but not limited to:


	•		the benefits and perceived benefits to us;


	•		the materiality and character of the related party ’ s direct and indirect interest;


	•		the availability of other sources for comparable products or services;


	•		the terms of the transaction; and


	•		the terms available to unrelated third parties under the same or similar circumstances.

In reviewing proposed related party transactions, the audit committee will only approve or ratify related party transactions that are in, or not inconsistent with, the best interests of us and our stockholders.

The transactions described below were consummated prior to our adoption of the formal, written policy described above, and therefore the foregoing policies and procedures were not followed with respect to the transactions. However, we believe that the terms obtained or consideration that we paid or received, as applicable, in connection with the transactions described were comparable to terms available or the amounts that would be paid or received, as applicable, in arm ’ s-length transactions.

Investors’ Rights Agreement

We have entered into an investors ’ rights agreement with certain holders of our common stock, including Dr. Diorio, our co-founder, vice chair and chief executive officer and entities affiliated with ARCH Venture Partners. Pursuant to the

- 18 -

Table of Contents

agreement, certain holders of our common stock have the right to demand that we file a registration statement, including a registration statement on Form S-3 if we qualify, or request that their shares be covered by a registration statement that we are otherwise filing. We will pay all expenses r elating to any demand registrations, Form S-3 registrations and piggyback registrations, other than underwriting discounts and selling commissions. As of March 31, 2019 , the holders of approximately 2,398,546 shares of our common stock are entitled to righ ts with respect to the registration of their shares under the Securities Act of 1933, as amended.

Voting Agreement

Prior to our IPO, the election of the members of the board of directors was governed by a voting agreement with certain of the holders of our outstanding capital stock, including Dr. Diorio and entities affiliated with ARCH Venture Partners. Upon the completion of our IPO, the obligations of the parties to the voting agreement terminated, and none of our stockholders has any special rights regarding the nomination, election or designation of members of the board of directors.

Sylebra Letter Agreement

On June 20, 2018, we entered into a letter agreement with Sylebra HK Company Limited, one of our significant stockholders, and Mr. Gibson. Among other things, pursuant to the letter agreement, we increased the size of our board to seven and appointed Mr. Gibson so serve as a director with a term expiring at our 2018 annual meeting of stockholders. Furthermore, we agreed, in connection with the 2018 annual meeting of stockholders, to nominate Mr. Gibson to stand for election. Other than as described herein, there are no arrangements or understandings between Mr. Gibson, on the one hand, and us or any other persons, on the other hand, pursuant to which Mr. Gibson was selected as a director.

Other Transactions

We have entered into employment agreements with our executive officers that, among other things, provide for certain severance and change of control benefits. For a description of these agreements, see “ Executive Compensation — Executive Employment Arrangements. ”

We have granted stock options to our executive officers. Pursuant to our outside director compensation policy, we have paid cash compensation and granted restricted stock units to our non-employee directors. For a description of these arrangements, see “ Executive Compensation. ”

We have entered into indemnification agreements with our directors and executive officers.

Limitations on Director and Officer Liability and Indemnification

Our certificate of incorporation and bylaws provide the indemnification of our directors and officers to the fullest extent permitted under the Delaware General Corporation Law. In addition, the certificate of incorporation provides that our directors shall not be personally liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director and that if the Delaware General Corporation Law is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of our directors shall be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law, as so amended.

As permitted by the Delaware General Corporation Law, we have entered into separate indemnification agreements with each of our directors and certain of our officers that require us, among other things, to indemnify them against certain liabilities which may arise by reason of their status as directors, officers or certain other employees. We maintain insurance policies under which our directors and officers are insured, within the limits and subject to the limitations of those policies, against certain expenses in connection with the defense of, and certain liabilities that might be imposed as a result of, actions, suits or proceedings to which they are parties by reason of being or having been directors or officers. The coverage provided by these policies may apply whether or not we would have the power to indemnify such person against such liability under the provisions of the Delaware General Corporation Law.

We believe that these provisions and agreements are necessary to attract and retain qualified persons as our officers and directors. At present, there is no pending litigation or proceeding involving our directors or officers for whom indemnification is required or permitted, and we are not aware of any threatened litigation or proceeding that may result in a claim for indemnification.

DIRECTOR INDEPENDENCE

Our common stock is listed on The Nasdaq Global Select Market. Under the rules of The Nasdaq Global Select Market, independent directors must comprise a majority of a listed company ’ s board of directors. In addition, the rules of The Nasdaq Global Select Market require that, subject to specified exceptions, each member of a listed company ’ s audit, compensation and nominating and governance committees must be independent. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended, or the Exchange Act. Under the rules of The Nasdaq Global Select Market, a director will only qualify as an “ independent director ” if, in the opinion of that company ’ s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Our board of directors has undertaken a review of its composition, the composition of its committees and the independence of our directors and considered whether any director has a material relationship with us that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our board of directors has determined that, other than Dr. Diorio, none of our current directors, has a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “ independent ” as that term is defined under the rules of The Nasdaq Global Select Market. Our board of directors also determined that Messrs. Sessler, Alberg and Bybee, who comprise our audit committee; Messrs. Bybee and Sessler and Ms. Wise, who comprise our compensation committee; and Messrs. van Oppen, Alberg and Bybee who comprise our nominating and governance committee, satisfy the independence standards for those committees established by applicable SEC rules and the rules of The Nasdaq Global Select Market. In making this determination, our board of directors considered the relationships that each non-employee director has with us and all other facts and circumstances our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director.
