1. Organization and Description of Business

~~OrganizationandDescription of Business~~

Adaptive Biotechnologies Corporation (“we,” “us” or “our”) is a commercial-stage company advancing the field of immune medicine by harnessing the inherent biology of the adaptive immune system to transform the diagnosis and treatment of disease. We believe the adaptive immune system is nature’s most finely tuned diagnostic and therapeutic for most diseases, but the inability to decode it has prevented the medical community from fully leveraging its capabilities. Our immune medicine platform applies our proprietary technologies to read the diverse genetic code of a patient’s immune system and aims to understand precisely how the immune system detects and treats disease in that patient. We capture these insights in our dynamic clinical immunomics database, which is underpinned by computational biology and machine learning, and use them to develop and commercialize clinical products and services that we are tailoring to each individual patient. We have commercial products and services and a robust pipeline of clinical products and services that we are designing to diagnose, monitor and enable the treatment of diseases, such as cancer and autoimmune ~~disorders and infectious diseases.~~disorders.

We were incorporated in the State of Washington on September 8, 2009 under the name Adaptive TCR Corporation. On December 21, 2011, we changed our name to Adaptive Biotechnologies Corporation. We are headquartered in Seattle, Washington.

Basisof Presentation and Principles of Consolidation

The unaudited condensed consolidated financial statements include the accounts of Adaptive Biotechnologies Corporation, Adaptive Biotechnologies B.V., our wholly-owned subsidiary, and Digital Biotechnologies, Inc., a corporate subsidiary we have ~~70%~~70% ownership interest in. The remaining interest in Digital Biotechnologies, Inc., held by certain of our related parties and their related family trusts, are shown in the unaudited condensed consolidated financial statements as noncontrolling interest. All intercompany transactions and balances ~~between Adaptive Biotechnologies Corporation, our wholly-owed subsidiary and Digital Biotechnologies, Inc.~~ have been eliminated upon consolidation.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the condensed consolidated financial statements, as well as the reported amounts of revenues and expenses during the periods presented. We base our estimates on historical experience and other relevant assumptions that we believe to be reasonable under the circumstances. Estimates are used in several areas including, but not limited to, estimates of progress to date for certain performance obligations and the transaction price for certain contracts with customers, share-based compensation, ~~including the fair value of stock,~~imputing interest for our revenue interest purchase agreement (the “Purchase Agreement”) that we entered into in September 2022, the provision for income taxes, including related reserves, and the analysis of goodwill impairment, among others. These estimates generally involve complex issues and require judgments, involve the analysis of historical results and prediction of future trends, can require extended periods of time to resolve and are subject to change from period to period. Actual results may differ materially from management’s estimates.

Unaudited Interim Condensed Consolidated Financial Statements

In our opinion, the accompanying unaudited condensed consolidated financial statements have been prepared in accordance with GAAP for interim financial information. These unaudited condensed consolidated financial statements include all adjustments necessary to fairly state our financial position and the results of our operations and cash flows for interim periods in accordance with GAAP. All such adjustments were of a normal, recurring nature. Interim-period results are not necessarily indicative of results of operations or cash flows for a full year or any subsequent interim period.

The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, ~~2021~~2022 filed with the ~~SEC~~Securities and Exchange Commission (“SEC”) on February ~~15, 2022.~~14, 2023.

~~Reclassification~~

We previously disclosed revenue bifurcated into sequencing and development financial statement captions. Beginning with the reporting period ended March 31, 2022, we changed how we classify revenue and now present total revenue on the unaudited condensed consolidated statements of operations. See Note 3, Revenue for additional disaggregation of revenue under our Immune Medicine and MRD market opportunities.

Restricted Cash

We had a restricted cash balance of ~~$2.4~~$2.9 million and ~~$2.1~~$2.4 million as of June 30, ~~2022~~2023 and December 31, ~~2021,~~2022, respectively. Our restricted cash primarily relates to certain balances we are required to maintain under lease arrangements for some of our property and facility leases.

~~Concentrations~~Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

Concentrations of Risk

We are subject to a concentration of risk from a limited number of suppliers, or in certain cases, single suppliers, for some of our laboratory instruments and materials. This risk is managed by targeting a quantity of surplus stock.

Cash, cash equivalents and marketable securities are financial instruments that potentially subject us to concentrations of credit risk. We invest in money market funds, United States (“U.S.”) government ~~debt securities, U.S. government~~treasury and agency securities, corporate bonds and commercial paper ~~and corporate bonds~~ with high-quality accredited financial institutions.

~~We recognize revenue in accordance with Accounting Standards Codification (“ASC”) Topic 606 (“ASC 606”),~~ Revenue ~~from Contracts with Customers~~Recognition~~. Under ASC 606, for~~

For all revenue-generating contracts, we perform the following steps to determine the amount of revenue to be recognized: (1) identify the contract or contracts; (2) determine whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (3) measure the transaction price, including the constraint on variable consideration; (4) allocate the transaction price to the performance obligations based on estimated selling prices; and (5) recognize revenue when (or as) we satisfy each performance obligation.

We derive revenue by providing diagnostic and research services in our Immune Medicine and ~~MRD~~Minimal Residual Disease (“MRD”) market opportunities. Our Immune Medicine revenue consists of revenue generated from (1) providing sample testing services for our commercial research product, immunoSEQ, to biopharmaceutical customers and academic institutions; (2) ~~providing our T-Detect COVID tests to clinical customers; and (3)~~ our collaboration agreements with Genentech, Inc. (“Genentech”) and other biopharmaceutical customers in areas of drug and target ~~discovery.~~discovery; and (3) providing our T-Detect COVID tests to clinical customers. Our MRD revenue consists of revenue generated from (1) providing our clonoSEQ report to clinical customers; (2) providing MRD sample testing services to biopharmaceutical customers and certain academic institutions, including investigator-led clinical trials; and (3) providing our clonoSEQ report or results to certain international laboratory sites through technology transfers.

For research customers who utilize either immunoSEQ or our MRD services, contracts typically include an amount billed in advance of services (“upfront”) and subsequent billings as sample results are delivered to the customer. Upfront amounts received are recorded as deferred revenue, which we recognize as revenue upon satisfaction of performance obligations. We have identified two typical performance obligations under the terms of our research service contracts: (1) the delivery of our immunoSEQ or MRD data for customer provided samples; and (2) related data analysis. We recognize revenue for both identified performance obligations as sample results are delivered to the customer. In periods where our sample estimates are reduced or a customer project is cancelled and, in either case, we have remaining related deferred revenue, we recognize revenue using a cumulative catch-up approach based on the proportion of samples delivered to date relative to the remaining samples expected to be delivered.

For agreements where we provide our clonoSEQ report to ordering physicians, we have identified one performance obligation: the delivery of a clonoSEQ report. We bill and receive payments for these transactions from commercial, government and medical ~~institutions and commercial and government third-party~~institution payors. As payment from the respective payors may vary based on the various reimbursement rates and patient responsibilities, we consider the transaction price to be variable and record an estimate of the transaction price, subject to the constraint for variable consideration, as revenue at the time of delivery. The estimate of transaction price is based on historical and expected reimbursement rates with the various payors, which are monitored in subsequent periods and adjusted, as necessary, based on actual collection experience.

Regarding our clonoSEQ coverage under Medicare, we bill an episode of treatment when we deliver the first eligible test report. This billing contemplates all necessary tests required during a patient’s treatment cycle, which is currently estimated at approximately four tests per patient, including the initial sequence identification test. Revenue recognition commences at the time the initial billable test report is delivered and is based upon cumulative tests delivered to date. We estimate the number of tests we expect to deliver over a patient’s treatment cycle based on historical testing frequencies for patients by indication. These estimates are subject to change as we develop more information about utilization over time. Any unrecognized revenue from the initial billable test is recorded as deferred revenue and is recognized either as we deliver our estimate of the remaining tests in a patient’s treatment cycle or when the likelihood becomes remote that a patient will receive additional testing.

The contract transaction price for agreements we enter into with biopharmaceutical customers to further develop and commercialize their therapeutics may consist of a combination of non-refundable upfront fees, separately priced MRD testing fees and milestone fees earned upon our customers’ achievement of certain regulatory approvals. Depending on the contract, these agreements include single or multiple performance obligations. Such performance obligations include providing services to support our customers’ therapeutic development efforts, including regulatory support for our technology intended to be utilized as part of our customers’ registrational trials, developing analytical plans for our data, participating on joint research committees, ~~and~~ assisting in completing a regulatory submission and providing MRD testing services related to customer-provided samples for ~~their~~our customers' regulatory submissions. Generally, the support services, excluding MRD testing services, are not distinct within the context of the contract and thus are accounted for as a single performance obligation. The transaction price allocated to the respective performance obligations is estimated using an adjusted market assessment approach for the regulatory support services and a standalone selling price for the estimated MRD testing services. At contract inception, we fully constrain any consideration related to regulatory milestones, as the achievement of such milestones is subject to third-party regulatory approval and the customers’ own submission decision-making. When MRD sample testing services are separately priced customer options, we assess if a material right exists and, if not, the customer option to purchase additional MRD sample testing services is not considered part of the contract. We recognize revenue related to MRD testing services over time using an output method based on the proportion of sample results delivered relative to the total amount of sample results expected to be delivered, when expected to be a faithful depiction of progress. We use the same method to recognize the regulatory support services. When an output method based on the proportion of sample results delivered is not expected to be a faithful depiction of progress, we utilize an input method using a cost-based model based on estimates of effort completed. Selecting the measure of progress and estimating progress to date requires significant judgment. Except for any non-refundable upfront fees, the other forms of compensation represent variable consideration. At contract inception, we fully constrain any consideration related to regulatory milestones, as the achievement of such milestones is subject to third-party regulatory approval and the customers’ own submission decision-making. Variable consideration related to regulatory milestones is estimated using the most likely amount method, where variable consideration is constrained until it is probable that a significant reversal of cumulative revenue ~~recognized~~ will not occur. Milestone payments for regulatory approvals, which are not within our customers’ control, are not considered probable of being achieved until those approvals are received. Determining whether regulatory milestone payments are probable is an area that requires significant judgment. In making this assessment, we evaluate scientific, clinical, regulatory and other risks, as well as the level of effort and investment required to achieve the respective milestone.

3. Revenue

~~Net Loss Per Share Attributable to Adaptive Biotechnologies Corporation Common Shareholders~~

We calculate basic net loss per share attributable to our common shareholders by dividing net loss attributable to us by our weighted-average number of shares of common stock outstanding for the period. The diluted net loss per share attributable to our common shareholders is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period determined using the treasury stock method. For purposes of this calculation, outstanding common stock warrants, outstanding stock options, nonvested restricted stock units and the maximum nonvested market-based restricted stock units eligible to be earned are considered common stock equivalents but have been excluded from the calculation of diluted net loss per share attributable to our common shareholders, as their effect is anti-dilutive.

During the ~~three~~six months ended June 30, ~~2021,~~2023, we recognized ~~$3.1~~$2.7 million in revenue related to ~~changes in estimates of total samples to be provided under certain of our agreements,~~ Medicare reimbursements resulting from our determination that the likelihood of additional testing for specific patients was remote, ~~and~~ cancelled customer contracts ~~all~~and a change in estimate of total samples to be provided under certain of our agreements, $0.4 million of which was recognized as Immune Medicine service revenue and $2.3 million of which was recognized as MRD service revenue.

During the six months ended June 30, 2022, we recognized ~~$2.8~~$2.8 million in revenue related to Medicare reimbursements resulting from our determination that the likelihood of additional testing for specific patients was remote, changes in estimates of total samples to be provided under certain of our agreements and cancelled customer contracts, ~~$0.2~~$0.2 million of which was recognized as Immune Medicine service revenue and ~~$2.6~~$2.6 million of which was recognized as MRD service revenue.

GenentechCollaboration Agreement

In December 2018, we entered into a worldwide collaboration and license agreement with Genentech (the “Genentech Agreement”) to leverage our capability to develop cellular therapies in oncology. Subsequent to receipt of regulatory approval in January 2019, we received a non-refundable, upfront payment of ~~$300.0~~$300.0 million in February 2019 and may be eligible to receive more than ~~$1.8~~$1.8 billion over time, including payments of up to ~~$75.0~~$75.0 million upon the achievement of specified regulatory milestones ($10.0 million of which was achieved in the three months ended June 30, 2023), up to ~~$300.0~~$300.0 million upon the achievement of specified development milestones and up to ~~$1,430.0~~$1,430.0 million upon the achievement of specified commercial milestones. In addition, we are separately able to receive tiered royalties at a rate ranging from the mid-single digits to the mid-teens on aggregate worldwide net sales of products arising from the strategic collaboration, subject to certain reductions, with aggregate minimum floors. Under the ~~agreement,~~Genentech Agreement, we are pursuing two product development pathways for novel T cell immunotherapies in which Genentech intends to use T cell receptors (“TCRs”) screened by our immune medicine platform to engineer and manufacture cellular medicines:

•

~~Shared Products. The shared products will use “off-the-shelf” TCRs identified against cancer antigens shared among patients (“Shared Products”).~~

•

Shared Products. The shared products will use “off-the-shelf” TCRs identified against cancer antigens shared among patients (“Shared Products”).

•

Personalized Product. The personalized product will use patient-specific TCRs identified by real-time screening of TCRs against cancer antigens in each patient (“Personalized Product”).

~~AdaptiveBiotechnologiesCorporation~~

~~Notesto Unaudited Condensed Consolidated Financial Statements (Continued)~~

~~(unaudited)~~

Under the terms of the ~~agreement,~~Genentech Agreement, we granted Genentech exclusive worldwide licenses to develop and commercialize TCR-based cellular therapies in the field of oncology, including licenses to existing shared antigen data packages. Additionally, Genentech has the right to determine which product candidates to further develop for commercialization purposes. We determined that this arrangement meets the criteria set forth in ~~ASC~~Accounting Standards Codification (“ASC”) Topic 808, Collaborative Arrangements (“ASC 808”), because both parties are active participants in the activity and are exposed to significant risks and rewards depending on the activity’s commercial failure or success. Because ASC 808 does not provide guidance on how to account for the activities under a collaborative arrangement, we applied the guidance in ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”) to account for the activities related to the Genentech Agreement.

In applying ASC 606, we identified the following performance obligations at the inception of the agreement:

We determined that none of the licenses, research and development services or obligations to participate on various committees were distinct within the context of the contract, given such rights and activities were highly interrelated and there was substantial additional research and development to further develop the licenses. We considered factors such as the stage of development of the respective existing antigen data packages, the subsequent development that would be required to both identify and submit a potential target for investigational new drug acceptance under both product pathways and the variability in research and development pathways given Genentech’s control of product commercialization. Specifically, under the ~~agreement,~~Genentech Agreement, Genentech is not required to pursue development or commercialization activities pertaining to both product pathways and may choose to proceed with one or the other. Accordingly, we determined that all of the identified performance obligations were attributable to one general performance obligation, which is to further the development of our TCR-specific platform, including data packages, and continue to make our TCR identification process available to Genentech to pursue either product pathway.

Separately, we have a responsibility to Genentech to enter into a supply and manufacturing agreement for patient-specific TCRs as it pertains to any Personalized Product therapeutic. We determined this was an option right of Genentech should they pursue commercialization of a Personalized Product therapy. Because of the uncertainty resulting from the early stage of development, the novel approach of our collaboration with Genentech and our rights to future commercial milestones and royalty payments, we determined that this option right was not a material right that should be accounted for at inception. As such, we will account for the supply and manufacturing agreement when entered into between the parties.

We determined the initial transaction price shall be made up of only the ~~$300.0~~$300.0 million upfront, non-refundable payment, as all potential regulatory and development milestone payments were probable of significant revenue reversal given their achievement was highly dependent on factors outside our control. As a result, these payments were fully constrained and were not included in the initial transaction price. In May 2023, one of the regulatory milestones was achieved, resulting in a $10.0 million addition to the transaction price, $7.7 million of which was recognized as ofrevenue in the three months ended June 30, ~~2022.~~2023 and $2.3 million of which was added to deferred revenue. We ~~excluded~~continue to exclude the commercial milestones and potential royalties from the transaction price, as those items relate predominantly to the license rights granted to Genentech and will be assessed when and if such events occur.

As there are potential substantive developments necessary, which Genentech may be able to direct, we determined that we would apply a proportional performance model to recognize revenue for our performance obligation. We measure proportional performance using an input method based on costs incurred relative to the total estimated costs of research and development efforts to pursue both the Shared Products and Personalized Product pathways. When any of the potential regulatory and development milestones are no longer fully constrained and are included in the transaction price, such amounts will be recognized using the cumulative catch-up method based on proportional performance at such time. We currently expect to recognize the revenue over a period of approximately ~~seven~~eight to ~~eight~~nine years from the effective date. This estimate of the research and development period considers pursuit options of development activities supporting both the Shared Products and ~~the~~ Personalized Product, but may be reduced or increased based on the various activities as directed by the joint committees, decisions made by Genentech, regulatory feedback or other factors not currently known.

WeIn total, we recognized ~~$13.8~~$17.5 million and ~~$17.2~~$13.8 million in Immune Medicine collaboration revenue during the three months ended June 30, ~~2022~~2023 and ~~2021,~~2022, respectively, and ~~$26.0~~$26.7 million and ~~$32.8~~$26.0 million in Immune Medicine collaboration revenue during the six months ended June 30, ~~2022~~2023 and ~~2021,~~2022, respectively, related to the Genentech Agreement. Costs related to the Genentech Agreement are included in research and development expenses.

4. Deferred Revenue

~~Deferred Revenue~~

Deferred revenue from ~~our~~the Genentech Agreement represents ~~$53.9~~$23.0 million and ~~$70.1~~$47.7 million of the current and non-current deferred revenue balances, respectively, as of June 30, ~~2022~~2023 and ~~$56.1~~$31.8 million and ~~$94.0~~$55.5 million of the current and non-current deferred revenue balances, respectively, as of December 31, ~~2021.~~2022. We expect our current deferred revenue to be recognized as revenue within 12 months. We expect the majority of our non-current deferred revenue to be recognized as revenue over a period of approximately four ~~to five~~ years from June 30, ~~2022.~~2023. This period of time represents an estimate of the research and development period to develop cellular therapies in oncology, which may be reduced or increased based on ~~the~~ various research and development activities.

We periodically review our available-for-sale securities to assess for credit impairment. Some of the factors considered in assessing impairment include the extent to which the fair value is less than the amortized cost basis, adverse conditions related to the security, an industry or geographic area, changes to security ratings or sector credit ratings and other relevant market data.

As of June 30, ~~2022,~~2023, we did not intend, nor were we more likely than not to be required, to sell our available-for-sale investments before the recovery of their amortized cost basis, which may be maturity. Based on our assessment, we concluded all impairment as of June 30, ~~2022~~2023 to be due to factors other than credit loss, such as changes in interest rates. A credit allowance was not recognized and the impairment of our available-for-sale securities was recorded in other comprehensive loss.

8. Revenue Interest Purchase Agreement

In September 2022, we entered into the Purchase Agreement with OrbiMed Royalty & Credit Opportunities IV, LP (“OrbiMed”), an affiliate of OrbiMed Advisors LLC, as collateral agent and administrative agent for the purchasers party thereto (the “Purchasers”). Pursuant to the Purchase Agreement, we received $125.0 million from the Purchasers at closing, less certain transaction expenses. We are also entitled to receive up to $125.0 million in subsequent installments as follows: (i) $75.0 million upon our request occurring no later than September 12, 2025 and (ii) $50.0 million upon our request in connection with certain permitted acquisitions occurring no later than September 12, 2025, in each case subject to certain funding conditions.

As consideration for such payments, the Purchasers have a right to receive certain revenue interests (the “Revenue Interests”) from us based on a percentage of all GAAP revenue. Payments in respect of the Revenue Interests shall be made quarterly within 45 days following the end of each fiscal quarter (each, a “Revenue Interest Payment”).

Accounting Treatment

We accounted for the transaction as long-term debt recorded at amortized cost using the effective interest rate method.

Adaptive Biotechnologies Corporation

Notes to Unaudited Condensed Consolidated Financial Statements (Continued)

(unaudited)

To determine the amortization of the Purchase Agreement obligation, we are required to estimate the amount and timing of future Revenue Interest Payments based on our estimate of the timing and amount of future revenues and calculate an effective interest rate which will amortize the obligation to zero over the amortization period. The calculated effective interest rate as of June 30, 2023 was 11.4%.

In connection with the Purchase Agreement, we incurred debt issuance costs of $0.6 million. Debt issuance costs have been recorded to long-term debt and are being amortized over the estimated term of the debt using the effective interest method, adjusted on a prospective basis for changes in the underlying assumptions and inputs.

The assumptions used in determining the expected repayment term of the obligation and amortization period of the issuance costs requires that we make estimates that could impact the short- and long-term classification of these costs, as well as the period over which these costs will be amortized. We periodically assess the amount and timing of expected Revenue Interest Payments based on internal forecasts. To the extent such payments are greater or less than our initial estimates or the timing of such payments is materially different than our original estimates, we will prospectively adjust the amortization of the revenue interest liability and the effective interest rate.

The following table sets forth the revenue interest liability, net activity during the six months ended June 30, 2023 (in thousands):


Revenue interest liability, net at December 31, 2022	$	125,360
Interest expense		3,531
Revenue interest payable		(1,883	)
Revenue interest liability, net at March 31, 2023		127,008
Interest expense		3,605
Revenue interest payable		(2,446	)

9. Commitments and Contingencies

~~Commitments and Contingencies~~

Legal Proceedings

We are subject to claims and assessments from time to time in the ordinary course of business. We will accrue a liability for such matters when it is probable that a liability has been incurred and the amount can be reasonably estimated. When only a range of possible loss can be established, the most probable amount in the range is accrued. If no amount within this range is a better estimate than any other amount within the range, the minimum amount in the range is accrued. We were not party to any material legal proceedings as of June 30, ~~2022.~~2023.

Indemnification Agreements

In the ordinary course of business, we may provide indemnification of varying scope and terms to vendors, lessors, customers and other parties with respect to certain matters including, but not limited to, losses arising out of breach of our agreements with them or from intellectual property infringement claims made by third parties. In addition, we have entered into indemnification agreements with members of our board of directors and certain of our executive officers that will require us to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. The maximum potential amount of future payments that we could be required to make under these indemnification agreements is, in many cases, unlimited. We have not incurred any material costs as a result of such indemnifications and are not currently aware of any indemnification claims.

11. Equity Incentive Plans

2009 Equity Incentive Plan

We adopted an equity incentive plan in 2009 (“2009 Plan”) that provided for the issuance of incentive and nonqualified common stock options and other share-based awards for employees, directors and consultants. Under the 2009 Plan, the exercise price for incentive and nonqualified stock options were not to be less than the fair market value of our common stock at the date of grant. Stock options granted under this plan expire no later than ten years from the grant date and vesting was established at the time of grant. Pursuant to the terms of the 2019 Plan, any shares subject to outstanding stock options originally granted under the 2009 Plan that terminate, expire or lapse for any reason without the delivery of shares to the holder thereof shall become available for issuance pursuant to awards granted under the 2019 Plan. While 0no shares are available for future ~~issuance~~grant under the 2009 Plan, it continues to govern outstanding equity awards granted thereunder.

2019 Equity Incentive Plan

The 2019 Plan became effective immediately prior to the closing of our initial public offering in July 2019. The 2019 Plan provides for the issuance of awards in the form of stock options and other share-based awards for employees, directors and consultants. Under the 2019 Plan, the stock option exercise price per share shall not be less than the fair market value of a share of stock on the effective date of grant, as defined by the 2019 Plan, unless explicitly qualified under the provisions of Section 409A or Section 424(a) of the Internal Revenue Code of 1986. Additionally, unless otherwise specified, stock options granted under this plan expire no later than ten years from the grant date and vesting is established at the time of grant. Except for certain stock option and restricted stock unit grants made to non-employee directors, stock options and restricted stock units granted under the 2019 Plan generally vest over a four-year period, subject to continuous service through each applicable vesting date. As of June 30, ~~2022,~~2023, we had ~~29,279,180~~35,014,382 shares of common stock authorized for issuance under the 2019 Plan.

Market-Based Restricted Stock Units

In addition to the restricted stock units described above, our board of directors approved ~~an award~~awards of market-based restricted stock units to our chief executive officer and chief scientific officer in March ~~2022.~~2023. The shares of common stock that may be earned under the ~~award,~~awards, each ranging from 0zero shares to ~~494,234~~709,220 shares, are calculated based upon our total shareholder return during a three-year performance period as measured against that of the group of companies comprising the S&P Biotechnology Select Industry Index as of the grant date, subject to certain adjustments to such index group. Except as expressly provided in the terms of ~~the award~~each award's agreement, vesting is subject to ~~our chief executive officer's~~the respective grantee's continuous service through the end of the three-year performance period. These market-based restricted stock units, along with those granted to our chief executive officer in March 2022, under which zero shares to 494,234 shares may be earned, remain outstanding as of June 30, 2023.

Grant Date Fair Value of Stock Options, Restricted Stock Units and Market-Based Restricted Stock Units Granted

The estimated grant date fair values of stock options granted during the six months ended June 30, ~~2022~~2023 and ~~2021~~2022 were estimated using the Black-Scholes option-pricing model with the following assumptions:


	Six Months Ended June 30,				Six Months Ended June 30,
	2022		2021		2023		2022
Fair value of common stock	$7.30 - $14.95		$34.41 - $66.50		$8.46		$7.30 - $14.95
Expected term (in years)	5.27 - 6.08		5.27 - 6.08		5.27 - 6.08		5.27 - 6.08
Risk-free interest rate	1.7% - 3.0%		0.5% - 1.1%		4.2% - 4.3%		1.7% - 3.0%
Expected volatility	68.2% - 71.0%		67.1% - 68.7%		71.2% - 71.6%		68.2% - 71.0%

The determination of the grant date fair value of stock options granted using a Black-Scholes option-pricing model is affected by the fair value of our common stock, as well as assumptions regarding a number of variables that are complex, subjective and generally require ~~significant~~ judgment to determine. The valuation assumptions were determined as follows:

Fair value of common stock—The fair value of each share of common stock is based on the closing price of our common stock on the date of grant, or other relevant determination date, as reported on The Nasdaq Global Select Market.

Expected term—The expected term of stock options granted to employees and non-employee directors is determined using the “simplified” method, as illustrated in ASC Topic 718, Compensation—Stock Compensation, as we do not have sufficient exercise history to determine a better estimate of expected term. Under this approach, the expected term is based on the midpoint between the vesting date and the end of the contractual term of the stock option.

Risk-free interest rate—We utilize a risk-free interest rate in the option valuation model based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected terms of the stock options.

Expected volatility—As we do not have sufficient trading history for our common stock, expected volatility is based on the historical volatility of our publicly traded industry peers utilizing a period of time consistent with our estimate of expected term.

Expected dividend yield—We do not anticipate paying any cash dividends in the foreseeable future and, therefore, use an expected dividend yield of 0zero in the option valuation model.

The weighted-average grant date fair value per share of stock options granted during the six months ended June 30, 2023 and 2022 was $5.61and ~~2021 was $7.36 and $26.52,~~$7.36, respectively.

~~Restructuring~~

In March 2022, we began implementing a restructuring plan to reduce operating costs and drive future growth aligned with the strategic reorganization of our business around our MRD and Immune Medicine market opportunities. Under this restructuring plan, we reduced our workforce by approximately 100 employees.

We incurred aggregate restructuring costs of $2.0 million, all of which was recognized in the six months ended June 30, 2022. These costs primarily related to one-time termination benefits and ongoing benefit arrangements, both of which included severance payments and extended benefits coverage support and were contingent upon the impacted employees’ execution and non-revocation of separation agreements. Our aggregate restructuring costs also included certain contract termination costs.

~~The activities related to our reduction in workforce were primarily completed in March 2022 and the $2.0 million aggregate restructuring costs were paid as of June 30, 2022.~~

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion and analysis of our financial condition and results of operations together with the unaudited condensed consolidated financial statements and related notes and the other financial information appearing elsewhere in this report, as well as the other financial information we file with the SEC from time to time. Some of the information contained in this discussion and analysis or set forth elsewhere in this report, including information with respect to our plans and strategy for our business and related financing, includes forward-looking statements that involve risks and uncertainties relating to our future plans, objectives, expectations, intentions and financial performance and the assumptions that underlie these statements.

As a result of many factors, including those factors set forth in the “Risk Factors” section of this report, our actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

Overview

We are advancing the field of immune medicine by harnessing the inherent biology of the adaptive immune system to transform the diagnosis and treatment of disease. We believe the adaptive immune system is nature’s most finely tuned diagnostic and therapeutic for most diseases, but the inability to decode it has prevented the medical community from fully leveraging its capabilities. Our immune medicine platform applies our proprietary technologies to read the diverse genetic code of a patient’s immune system and aims to understand precisely how the immune system detects and treats disease in that patient. We capture these insights in our dynamic clinical immunomics database, which is underpinned by computational biology and machine learning, and use them to develop and commercialize clinical products and services that we are tailoring to each individual patient. We have commercial products and services and a robust pipeline of clinical products and services that we are designing to diagnose, monitor and enable the treatment of diseases, such as cancer and autoimmune ~~disorders~~disorders. Our existing and ~~infectious diseases.~~

Our immune medicine platform is the foundation for our expanding suite of products and services. The cornerstone of our platform and core immunosequencing product, immunoSEQ, serves as our underlying research and development engine and generates revenue from biopharmaceutical and academic customers.

Leveraging our collaboration with Microsoft, we are creating the TCR-Antigen Map. We are using this map to develop research solutions by disease, called immunoSEQ T-MAP, and a diagnostic product for many diseases from a single blood test, called T-Detect.

Regarding our specific products and pipeline, T-Detect COVID, for which we have received Emergency Use Authorization, is designed to confirm past SARS-CoV-2 infection, the virus that causes COVID-19. It is the first indication for the T-Detect product line. In June 2022, we launched a second indication, T-Detect Lyme, which is designed to help diagnose early Lyme disease. In addition, we have confirmed signals in Crohn’s disease, celiac disease and multiple sclerosis, and we have identified signals in ulcerative colitis and rheumatoid arthritis. In the future ~~we intend to sell other diagnostic~~commercial products and services ~~including other indications for T-Detect.~~are aligned to two markets which we refer to as MRD and Immune Medicine.

Our first clinical diagnostic product, clonoSEQ, is the first test authorized by the Food and Drug Administration for the detection and monitoring of ~~MRD~~minimal residual disease in patients with multiple myeloma, B cell acute lymphoblastic leukemia and chronic lymphocytic leukemia, and is also available as a CLIA-validated laboratory developed test for patients with other lymphoid cancers. We disclose our clonoSEQ test volume, which includes the number of clonoSEQ reports and results we have provided to ordering physicians in the United States and international technology transfer sites. These volumes do not include sample results from our biopharmaceutical customers or academic institutions utilizing our MRD services.

Historically, we have sold immunoSEQ as a fee-for-service offering. These research offerings have comprised the majority of our revenue to date, although our business is pursuing broader opportunities. As we continue to expandcancers, including diffuse large B-cell lymphoma. With the use of ~~our~~ clonoSEQ, ~~diagnostic tests, develop T-Detect~~we are transforming how lymphoid cancers are treated by working with providers, pharmaceutical partners and develop and commercialize therapeutic product candidates with our drug discovery collaborator, we expect our mix of revenue to shift to clinical products and services, which we believe will become our largest sources of revenue.

Immune Medicine leverages our platform’s proprietary ability to sequence, map, pair and characterize T cell receptors (“TCRs”) and B cell receptors (“BCRs”) at scale to drive opportunities in cancer, autoimmune disorders, infectious diseases and neurodegenerative disorders. The cornerstone of our platform and core immunosequencing product, immunoSEQ, serves as our underlying research and development engine and generates revenue from biopharmaceutical and academic customers. Leveraging our collaboration with Microsoft Corporation, we are creating the TCR-Antigen Map. We are ~~actively pursuing opportunities~~using the TCR-Antigen Map to ~~deepen our relationships with current customers~~identify and initiate relationships with new customers.

~~The activities related to our reduction in workforce were primarily completed in March 2022 and the $2.0 million aggregate restructuring costs were paid as of June 30, 2022.~~

~~Revenue Reclassification and clonoSEQ Test Volume~~

We previously disclosed revenue bifurcated into sequencing and development financial statement captions. Beginning with the reporting period ended March 31, 2022, we changed how we classify revenue and now present total revenue on the unaudited condensed consolidated statements of operations included elsewhere in this report. We disaggregate revenue under our Immune Medicine and MRD market opportunities in Note 3 of the accompanying notes to the unaudited condensed consolidated financial statements included elsewhere in this report.

Components of Results of Operations

Revenue

We derive revenue by providing diagnostic and research services in our Immune Medicine and MRD market opportunities. Our Immune Medicine revenue consists of revenue generated from (1) providing sample testing services for our commercial research product, immunoSEQ, to biopharmaceutical customers and academic institutions; (2) ~~providing our T-Detect COVID tests to clinical customers; and (3)~~ our collaboration agreements with Genentech and other biopharmaceutical customers in areas of drug and target ~~discovery.~~discovery; and (3) providing our T-Detect COVID tests to clinical customers. Our MRD revenue consists of revenue generated from (1) providing our clonoSEQ report to clinical customers; (2) providing MRD sample testing services to biopharmaceutical customers and certain academic institutions, including investigator-led clinical trials; and (3) providing our clonoSEQ report or results to certain international laboratory sites through technology transfers. We disclose our clonoSEQ test volume, which includes the number of clonoSEQ reports and results we have provided to ordering physicians in the United States and international technology transfer sites. These volumes do not include sample results from our biopharmaceutical customers or academic institutions utilizing our MRD services.

For our research customers, which include biopharmaceutical customers and academic institutions for both our immunoSEQ and MRD services, delivery of the respective test results may include some level of professional support and analysis. Terms with biopharmaceutical customers generally include non-refundable payments made in advance of services (“upfront ~~payments,~~payments”), which we record as deferred revenue. For all research customers, we recognize revenue as we deliver sequencing results. From time to time, we offer discounts in order to gain rights and access to certain datasets. Revenue is recognized net of these discounts and costs associated with these services are reflected in cost of revenue. In periods where our sample estimates are reduced or a customer project is cancelled and, in either case, we have remaining related deferred revenue, we recognize revenue using a cumulative catch-up approach based on the proportion of samples delivered to date relative to the remaining samples expected to be delivered. Certain of our MRD revenue arrangements with biopharmaceutical customers include consideration in the form of regulatory milestones upon regulatory approval of the respective biopharmaceutical partners’ therapeutics. Such revenue is constrained from recognition until it becomes probable that such milestone will be achieved.

Under certain agreements with our biopharmaceutical customers who seek access to our platform to support their therapeutic development activities, revenues are generated from research and development support services that we provide. These agreements may include substantial non-refundable upfront payments, which we recognize over time as we perform the respective services. Revenue recognized from these activities relate primarily to ~~our~~the Genentech Agreement.

For our clinical customers, we primarily derive revenue from providing our clonoSEQ report to ordering physicians. We bill commercial, government and medical ~~institutions and commercial and government~~institution payors based on reports delivered to ordering physicians. Amounts paid for clonoSEQ by commercial, government and medical ~~institutions and commercial and government~~institution payors vary based on respective reimbursement rates and patient responsibilities, which may differ from our targeted list price. We recognize clinical revenue by evaluating customer payment history, contracted reimbursement rates, if applicable, and other adjustments to estimate the amount of revenue that is collectible.

For our clonoSEQ coverage under Medicare, we bill an episode of treatment when we deliver the first eligible test report. This billing contemplates all necessary tests required during a patient’s treatment cycle, which is currently estimated at approximately four tests per patient, including the initial sequence identification test. Revenue recognition commences at the time the initial billable test report is delivered and is based upon cumulative tests delivered to date. Any unrecognized revenue from the initial billable test is recorded as deferred revenue and recognized either as we deliver our estimate of the remaining tests in a patient’s treatment cycle or when the likelihood becomes remote that a patient will receive additional testing.

We expect revenue to increase over the long term, particularly as the mix of revenue migrates to clinical diagnostics and drug discovery. The pace by which this mix migrates will be determined by the level of customer adoption and frequency of use of our products and services.term. Our revenue may fluctuate from period to period due to the uncertain nature of delivery of our products and services, the achievement of milestones by our customers, timing of expenses incurred, changes in estimates of total anticipated costs related to ~~our~~the Genentech Agreement and other events not within our control, such as the delivery of customer samples or customer decisions to no longer pursue their development initiatives.

Due to the ongoing uncertainties related to the COVID-19 pandemic, we may experience variability in revenue in the near term as our customers’ abilities to procure samples for their research initiatives change, as customer initiatives evolve and as clinical testing is impacted by the pandemic.

Cost of Revenue

Cost of revenue includes the cost of materials, personnel-related expenses (including salaries, benefits and share-based compensation), shipping and handling expenses, equipment costs, ~~and~~ allocated facility costs associated with processing samples and professional support ~~for~~costs related to our service revenue activities. Allocated facility costs include depreciation of laboratory equipment, as well as allocated facility occupancy and information technology costs. Costs associated with processing samples are recorded as expense, regardless of the timing of revenue recognition. As such, cost of revenue and related volume does not always trend in the same direction as revenue recognition and related volume. Additionally, costs to support ~~our~~the Genentech Agreement are a component of our research and development expenses.

Adaptive Biotechnologies Corporation

~~BiotechnologiesCorporation~~

We expect cost of revenue to increase in absolute dollars as we grow our sample testing volume and make near-term investments in laboratory ~~automation and facilities,~~consolidation, but the cost per sample to decrease over the long term due to the efficiencies we may gain as assay volume increases from improved utilization of our laboratory capacity, automation and other value engineering initiatives. If our sample volume throughput is reduced, ~~as a result of the COVID-19 pandemic or otherwise,~~ cost of revenue as a percentage of total revenue may be adversely impacted due to fixed overhead costs.

Research and Development Expenses

Research and development expenses consist of laboratory materials costs, personnel-related expenses (including salaries, benefits and share-based compensation), equipment costs, allocated facility costs, information technology expenses and contract service expenses. Research and development activities support further development and refinement of existing assays and products, discovery of new technologies and investments in our immune medicine platform. We also include in research and development expenses the costs associated with software development of applications to support future commercial opportunities, as well as development activities to support laboratory scaling and workflow. We are currently conducting research and development activities for several products and services and we typically use our laboratory materials, personnel, facilities, information technology and other development resources across multiple development programs. Additionally, certain of these research and development activities benefit more than one of our product opportunities. We dohave not ~~track~~historically tracked research and development expenses by specific product candidates.

AThe costs to support the Genentech Agreement are a component of our research and development expenses. Additionally, a component of our research and development expenses are costs supporting clinical and analytical validations to obtain regulatory approval for future clinical products and services. ~~Additionally, the costs to support our Genentech Agreement are a component of our research and development expenses.~~ Some of these activities have generated and may in the future generate ~~Immune Medicine collaboration~~ revenue.

We expect research and development expenses to ~~experience modest increases~~decrease in the short ~~term. However, we expect research~~term and ~~development expenses~~ to decrease as a percentage of revenue in the long term, although the percentage may fluctuate from period to period due to the timing and extent of our development and commercialization efforts.

Sales and Marketing Expenses

Sales and marketing expenses include personnel-related expenses (including salaries, benefits and share-based compensation) for commercial sales, product and account management, marketing, reimbursement, medical education and business development personnel that support commercialization of our platform products. In addition, these expenses include external costs such as advertising expenses, customer education and promotional expenses, market analysis expenses, conference fees, travel expenses and allocated facility costs.

We expect ~~our~~ sales and marketing expenses to experience ~~modest increases~~moderate decreases in the short term. In the long term, we expect sales and marketing expenses to increase in absolute dollars as we increase marketing activities to drive awareness and adoption of our products and services. However, we expect sales and marketing expenses to decrease as a percentage of revenue in the long term, subject to fluctuations from period to period due to the timing and magnitude of these expenses.

General and Administrative Expenses

General and administrative expenses include personnel-related expenses (including salaries, benefits and share-based compensation) for our personnel in executive, legal, finance and accounting, human resources and other administrative functions, including third-party clinical billing services. In addition, these expenses include insurance costs, external legal costs, accounting and tax service expenses, consulting fees and allocated facility costs.

We expect ~~minimal growth in our~~ general and administrative expenses to experience moderate decreases in the short ~~term. In the long~~ term ~~we expect these expenses~~and to decrease as a percentage of revenue asin the long term.

Interest expense includes costs associated with our revenue ~~increases.~~interest liability related to the Purchase Agreement and noncash interest costs associated with the amortization of the related deferred issuance costs. We impute the related interest expense using the effective interest rate method. We calculate an effective interest rate which will amortize our related obligation to zero over the anticipated repayment period. A significant increase or decrease in or changes in timing of forecasted revenue will prospectively impact our interest expense.

Adjusted EBITDA

Adjusted EBITDA is a non-GAAP financial measure that we define as net loss attributable to Adaptive Biotechnologies Corporation adjusted for interest and other income, net, interest expense, income tax (expense) benefit, depreciation and amortization expense, restructuring expense and share-based compensation expense.

Management uses Adjusted EBITDA to evaluate the financial performance of our business and the effectiveness of our business strategies. We present Adjusted EBITDA because we believe it is frequently used by analysts, investors and other interested parties to evaluate companies in our industry and it facilitates comparisons on a consistent basis across reporting periods. Further, we believe it is helpful in highlighting trends in our operating results because it excludes items that are not indicative of our core operating performance.

Adjusted EBITDA has limitations as an analytical tool and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. We may in the future incur expenses similar to the adjustments in the presentation of Adjusted EBITDA. In particular, we expect to incur meaningful share-based compensation expense in the future. Other limitations include that Adjusted EBITDA does not reflect:

•

all expenditures or future requirements for capital expenditures or contractual commitments;

•

changes in our working capital needs;

•

interest expense, which is an ongoing element of our costs to operate;

•

income tax (expense) benefit, which may be a necessary element of our costs and ability to operate;

•

the costs of replacing the assets being depreciated and amortized, which will often have to be replaced in the future;

•

the noncash component of employee compensation expense; and

•

the impact of earnings or charges resulting from matters we consider not to be reflective, on a ~~smaller portfolio.~~recurring basis, of our ongoing operations, such as our March 2022 restructuring and reduction in workforce.

Adaptive Biotechnologies Corporation

In addition, Adjusted EBITDA may not be comparable to similarly titled measures used by other companies in our industry or across different industries.

The following is a reconciliation of net loss attributable to Adaptive Biotechnologies Corporation, the most directly comparable GAAP financial measure, to Adjusted EBITDA for the periods presented (in thousands):

See Note 11 of the accompanying notes to the unaudited condensed consolidated financial statements included elsewhere in this report for details on our share-based compensation expense.

Liquidity and Capital Resources

We have incurred losses since inception and have incurred negative cash flows from operations since inception through June 30, ~~2022,~~2023, with the exception of certain 2019 periods for which we had positive cash flows from operations. As of June 30, ~~2022~~,2023, we had an accumulated deficit of ~~$833.7~~$1,024.6 million.

We have funded our operations to date principally from the sale of convertible preferred stock and common stock, and, to a lesser extent, ~~revenue.~~revenue and proceeds from the Purchase Agreement. Pursuant to the Purchase Agreement entered into in September 2022, we received net cash proceeds of $124.4 million, after deducting issuance costs. We are also entitled to receive up to $125.0 million in subsequent installments as follows: (i) $75.0 million upon our request occurring no later than September 12, 2025 and (ii) $50.0 million upon our request in connection with certain permitted acquisitions occurring no later than September 12, 2025, in each case subject to certain funding conditions. As of June 30, ~~2022,~~2023, we had cash, cash equivalents and marketable securities of ~~$450.7~~$417.2 million.

~~AdaptiveBiotechnologiesCorporation~~

We believe our existing cash, cash equivalents and marketable securities will be sufficient to fund our operating expenses and capital expenditure requirements through at least the next 12 months. We may consider raising additional capital to expand our business, to pursue strategic investments, to take advantage of financing opportunities or for other reasons.

If our available cash, cash equivalents and marketable securities balances and anticipated cash flows from operations are insufficient to satisfy our liquidity requirements, we may seek to sell additional equity or convertible debt securities, enter into a credit facility or another form of third-party funding or seek other debt financing. The sale of equity and convertible debt securities may result in dilution to our shareholders and, in the case of preferred equity securities or convertible debt, those securities could provide for rights, preferences or privileges senior to those of our common stock. The terms of debt securities issued or borrowings pursuant to a credit agreement could impose significant restrictions on our operations. This additional capital may not be available on reasonable terms, or at all.

We plan to utilize the existing cash, cash equivalents and marketable securities on hand primarily to fund our continued research and development initiatives for our ~~pipeline candidates and~~ drug discovery initiatives, ~~our ongoing investments in our immune medicine platform and~~ our commercial and marketing activities associated with clonoSEQ and our ~~clinical products and services. We also expect to make capital expenditures~~continued investments in ~~the near term related to~~streamlining our laboratory ~~space and expect to continue investing in laboratory equipment and operations to support our anticipated growth.~~operations. Cash in excess of immediate requirements is invested in accordance with our investment policy, primarily with a view to capital preservation and liquidity. Currently, our funds are held in money market funds and marketable securities consisting of ~~U.S.~~United States government ~~debt securities~~treasury and ~~corporate bonds.~~agency securities.

Adaptive Biotechnologies Corporation

While we may experience variability in revenue in the near term, over the long-term we expect revenue from our current and future products and services to grow. Accordingly, we expect our accounts receivable and inventory balances to increase. Our levels of accounts receivable may fluctuate relative to our revenue for a number of reasons, including the timing of milestone triggers and related payment of those milestones, as well as reductions in revenue derived from the upfront payment received under the Genentech Agreement and an increase in revenue generated from clinical customers, which may result in more billings in arrears as opposed to upfront payments. Any increase in accounts receivable and inventory may not be completely offset by increases in accounts payable and accrued expenses, which could result in greater working capital requirements.

Contractual Obligations

There have been no material changes outside the ordinary course of business to our contractual obligations and commitments as previously disclosed in our Annual Report on Form 10-K for the year ended December 31, ~~2021~~ 2022 filed with the SEC on February ~~15, 2022.~~ 14, 2023.

See N~~ote~~Note 7 and Note 8 of the accompanying notes to the unaudited condensed consolidated financial statements included elsewhere in this report for more information regarding our contractual obligations relating to lease ~~agreements.~~agreements and the Purchase Agreement, respectively.

While we may experience variability in revenue in the near term, as long-term revenue from sales of our current and future products and services is expected to grow, we expect our accounts receivable and inventory balances to increase.

~~Cash Flows~~

	2022			2021			2023			2022

Net cash provided by financing activities		6,739			20,942			2,141			6,739

Operating Activities

Cash used in operating activities during the six months ended June 30, 2023 was $82.7 million, which was primarily attributable to a net loss of $105.5 million and a net change in operating assets and liabilities of $24.0 million, partially offset by noncash share-based compensation of $32.0 million, noncash depreciation and amortization of $7.5 million, noncash lease expense of $3.6 million, noncash interest expense related to the Purchase Agreement of $2.8 million and inventory reserve expense of $0.8 million. The net change in operating assets and liabilities was primarily driven by a $13.9 million reduction in deferred revenue related primarily to revenue recognized from the Genentech Agreement, a $7.9 million reduction in accounts payable and accrued liabilities driven largely by the payout of our corporate bonus during the three months ended March 31, 2023, a $6.5 million increase in inventory and a $4.5 million decrease in operating lease right-of-use assets and liabilities. These changes were partially offset by an $8.5 million decrease in accounts receivable, net primarily related to collections from our biopharmaceutical customers.

Cash used in operating activities during the six months ended June 30, 2022 was $111.5 million, which was primarily attributable to a net loss of $114.9 million and a net change in our operating assets and liabilities of $41.7 million, partially offset by noncash share-based compensation of $27.0 million, noncash depreciation and amortization of $11.7 million, noncash lease expense of $3.6 million and a research and development inventory reserve charge of $2.8 million. The net change in our operating assets and liabilities was primarily due to a $24.2 million reduction in deferred revenue primarily related to revenue recognized from the Genentech Agreement, a reduction in accounts payable and accrued liabilities of $9.0 million driven largely by the payout of our corporate bonus during the three months ended March 31, 2022, an increase in accounts receivable of $6.3 million, which includes the $1.0 million regulatory milestone recognized during the three months ended June 30, 2022, and an increase in inventory of $2.3 million.

Investing Activities

Cash ~~used in operating~~provided by investing activities during the six months ended June 30, ~~2021~~2023 was ~~$95.5~~$100.3 million, which was primarily attributable to ~~a net loss~~proceeds from maturities of ~~$89.9 million and a net change in our operating assets and liabilities~~marketable securities of ~~$38.5~~$295.4 million, partially offset by ~~noncash share-based compensation~~purchases of ~~$19.7 million, noncash depreciation and amortization~~marketable securities of ~~$9.8~~$188.5 million and ~~noncash lease expense~~purchases of ~~$3.5~~property and equipment of $6.6 million. The net change in our operating assets and liabilities was primarily due to a $33.7 million reduction in deferred revenue primarily related to revenue recognized from the Genentech Agreement, an increase in inventory of $4.5 million, an increase in accounts receivable of $4.1 million and a reduction in accounts payable and accrued liabilities of $2.5 million, all of which were partially offset by an increase in operating lease liabilities of $4.5 million and reductions in prepaid expenses and other assets of $2.0 million.

~~AdaptiveBiotechnologiesCorporation~~

~~Investing Activities~~

Cash provided by investing activities during the six months ended June 30, 2022 was $42.4 million, which was primarily attributable to proceeds from maturities of marketable securities of $136.0 million, partially offset by purchases of marketable securities of $85.2 million and purchases of property and equipment of $8.4 million.

Financing Activities

Cash provided by ~~investing~~financing activities during the six months ended June 30, ~~2021~~2023 was ~~$135.3~~$2.1 million, which was ~~primarily~~ attributable to proceeds from ~~maturities~~the exercise of ~~marketable securities of $269.5 million, partially offset by purchases of marketable securities of $96.4 million and purchases of property and equipment of $37.9 million.~~stock options.

~~Financing Activities~~

Cash provided by financing activities during the six months ended June 30, 2022 was $6.7 million, which was attributable to proceeds from the exercise of stock options.

~~Cash provided by financing activities during the six months ended June 30, 2021 was $20.9 million, which was primarily attributable to proceeds from the exercise of stock options of $20.5 million.~~

Net Operating Loss Carryforwards

Utilization of our net operating loss (“NOL”) carryforwards and credits may be subject to a substantial annual limitation due to the ownership change limitations provided by Section 382 of the Internal Revenue Code of 1986 (“Section 382”) and similar state provisions. The annual limitation may result in the expiration of NOL carryforwards and credits before utilization. If there should be an ownership change, our ability to utilize our NOL carryforwards and credits could be limited. We have completed a Section 382 analysis for changes in ownership through December 31, 2020 and continue to monitor for changes that could trigger a limitation. Based on this analysis, we do not expect to have any permanent limitations on the utilization of our federal NOLs. Under the Tax Cuts and Jobs Act of 2017, federal NOLs incurred in 2018 and future years may be carried forward indefinitely, but the deductibility of such federal NOLs is subject to an annual limitation. NOLs generated prior to 2018 are eligible to be carried forward up to 20 years. Based on the available objective evidence, management determined that it was more likely than not that the net deferred tax assets would not be realizable as of December 31, ~~2021.~~2022. Accordingly, management applied a full valuation allowance against net deferred tax assets as of December 31, ~~2021.~~2022.

Critical Accounting Policies and Estimates

We have prepared the unaudited condensed consolidated financial statements in accordance with GAAP. Our preparation of these unaudited condensed consolidated financial statements requires us to make estimates, assumptions and judgments that affect the reported amounts of assets, liabilities and related disclosures at the date of the unaudited condensed consolidated financial statements, as well as revenue and expense recorded during the reporting periods. We evaluate our estimates and judgments on an ongoing basis. We base our estimates on historical experience and or other relevant assumptions that we believe to be reasonable under the circumstances. Estimates are used in several areas, including, but not limited to, estimates of progress to date for certain performance obligations and the transaction price for certain contracts with customers, imputing interest for the Purchase Agreement, the provision for income taxes, including related reserves, and the analysis of goodwill impairment, among others. These estimates generally involve complex issues and require judgments, involve the analysis of historical results and prediction of future trends, can require extended periods of time to resolve and are subject to change from period to period. Actual results may differ materially from management’s estimates.

While our significant accounting policies are described in more detail in our Annual Report on Form 10-K for the year ended December 31, ~~2021~~2022 filed with the SEC on February ~~15, 2022,~~14, 2023, as well as in Note 2 of the accompanying notes to the unaudited condensed consolidated financial statements included elsewhere in this report, we believe the following accounting policies are critical to the judgments and estimates used in the preparation of the unaudited condensed consolidated financial statements:

•

revenue recognition;

•

imputing interest for the Purchase Agreement; and

•

goodwill.

•

~~revenue recognition; and~~

•

~~goodwill.~~

There have been no material changes to our critical accounting policies and estimates as previously disclosed in our Annual Report on Form 10-K for the year ended December 31, ~~2021~~2022 filed with the SEC on February ~~15, 2022.~~14, 2023.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

We are exposed to market risk for changes in interest rates related primarily to our cash and cash equivalents and marketable securities. As of June 30, ~~2022,~~2023, there have been no material changes to our market risks as previously disclosed in our Annual Report on Form 10-K for the year ended December 31, ~~2021~~2022 filed with the SEC on February ~~15, 2022.~~14, 2023. We do not enter into investments for trading purposes and have not used any derivative financial instruments to manage our interest rate risk exposure.

Item 4. Controls and Procedures

Under the supervision and with the participation of our management, including our chief executive officer and chief financial officer, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) as of the end of the period covered by this report. Based on that evaluation, our chief executive officer and chief financial officer have concluded that our disclosure controls and procedures were effective as of June 30, ~~2022.~~2023. There was not any change in our internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) during the three months ended June 30, ~~2022~~2023 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we may be subject to legal proceedings. We are not currently a party to or aware of any proceedings that we believe will have, individually or in the aggregate, a material adverse effect on our business, financial condition or results of operations. Regardless of outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Item 1A. Risk Factors

Investing in our common stock involves a high degree of risk. We operate in a rapidly changing environment that involves a number of risks that could materially affect our business, financial condition or future results, some of which are beyond our control. In addition to the other information set forth in this report, the risks and uncertainties that we believe are most important for you to consider are discussed in Part I, Item 1A under the caption “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, ~~2021~~2022 filed with the SEC on February ~~15, 2022.~~14, 2023. The risk factors may be important to understanding other statements in this report and should be read in conjunction with the unaudited condensed consolidated financial statements and related notes in this report. The occurrence of any single risk or any combination of risks could materially and adversely affect our business, operations, product pipeline, operating results, financial condition or liquidity, and consequently, the value of our securities. Further, additional risks that we currently do not know about or that we currently believe to be immaterial may also impair our business, financial condition, operating results and prospects.

There have been no material changes to the risk factors described in our Annual Report on Form 10-K for the year ended December 31, ~~2021~~2022 filed with the SEC on February ~~15, 2022.~~14, 2023.
