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,
autoimmune disorders 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. We expect to launch a second indication, T-Detect Lyme,
during this year's Lyme season. 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 products and services, including other indications for
T-Detect.

Our therapeutic product candidates, being developed under the Genentech
Agreement, leverage our platform to identify specific receptors on immune cells
to develop into cellular therapies in oncology. We also extended our platform to
identify highly potent neutralizing antibodies against SARS-CoV-2 and we believe
this differentiated approach may be leveraged across multiple disease states.

Our first clinical diagnostic product, clonoSEQ, is the first test authorized by
the Food and Drug Administration for the detection and monitoring of MRD 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 now 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 expand the use
of our clonoSEQ diagnostic tests, develop and commercialize T-Detect 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.

                      Adaptive Biotechnologies Corporation


We are actively pursuing opportunities to deepen our relationships with current
customers and initiate relationships with new customers. We have an experienced,
specialty salesforce that is targeting department heads, laboratory directors,
principal investigators, core facility directors, clinicians, payors, research
scientists and pathologists at leading academic and research institutions,
biopharmaceutical companies and contract research organizations. As MRD
assessment becomes standard practice for patient management across a range of
blood cancers, we believe it will be essential for clinicians and patients to
have access to a highly accurate, sensitive and standardized MRD assessment
tool. We are focused on establishing and maintaining collaborative relationships
with payors, developing health economic evidence and building billing and
patient access infrastructure to expand reimbursement coverage for our clinical
diagnostics. We continue to seek expanded coverage of our clonoSEQ diagnostic
test and have successfully expanded coverage through contractual agreements or
positive medical policies with Medicare and several of the largest national
private health insurers in the United States.

We recognized revenue of $38.6 million and $38.4 million for the three months
ended March 31, 2022 and 2021, respectively. Net loss attributable to Adaptive
Biotechnologies Corporation was $62.7 million and $40.6 million for the three
months ended March 31, 2022 and 2021, respectively. We have funded our
operations to date principally from the sale of convertible preferred stock and
common stock and, to a lesser extent, revenue. As of March 31, 2022 and December
31, 2021, we had cash, cash equivalents and marketable securities of $500.7
million and $570.2 million, respectively.

Reduction in Workforce



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 estimate that we will incur aggregate restructuring costs of approximately
$2.0 million, all of which has been recognized in the three months ended March
31, 2022. These costs primarily relate to one-time termination benefits and
ongoing benefit arrangements, both of which include severance payments and
extended benefits coverage support and are contingent upon the impacted
employees' execution and non-revocation of separation agreements. Our estimated
aggregate restructuring costs also include certain contract termination costs.

The activities related to our reduction in workforce were primarily completed in
March 2022 and $1.4 million of the $2.0 million aggregate restructuring costs
were paid as of March 31, 2022. The remaining $0.6 million in cash payments are
expected to be disbursed in the year ended December 31, 2022.

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. 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 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 upfront 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.

                                       24
--------------------------------------------------------------------------------
                      Adaptive Biotechnologies Corporation


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 Genentech Agreement.

For our clinical customers, we primarily derive revenue from providing our
clonoSEQ report to ordering physicians. We bill medical institutions and
commercial and government payors based on reports delivered to ordering
physicians. Amounts paid for clonoSEQ by medical institutions and commercial and
government 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. 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
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 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 Genentech Agreement are a component
of our research and development expenses.

We expect cost of revenue to increase in absolute dollars as we grow our sample
testing volume and make investments in laboratory automation and facilities, 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, 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 do not track research and development expenses by
specific product candidates.

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.

                                       25
--------------------------------------------------------------------------------
                      Adaptive Biotechnologies Corporation


We expect research and development expenses to experience moderate increases in
the short term. However, we expect research 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 consist primarily of personnel-related expenses 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 moderate increases in
the short term. In the long term, we expect sales and marketing expenses to
increase in absolute dollars as we expand our commercial sales, marketing and
business development teams and 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 consist primarily of 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 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 our general and administrative expenses to experience moderate decreases in the short term driven by reduced headcount. In the long term, we expect these expenses to decrease as a percentage of revenue as revenue increases.
