Dear Shareholders,
Over the last year, we   ve worked to deliver the best testing for patients
and clinicians, both in terms of testing accuracy and in the service
provided. In order to accomplish this goal, the entire company focused
on improving every aspect of our core product offering, AVISE CTD.
We were successful in accomplishing the goals we set for 2023 and have
positioned ourselves to achieve further progress towards operating a
profitable company.

Key Metrics
ASP is the Opportunity
Our primary focus this past year, which will continue into 2024, was to improve the realized
reimbursed rate we obtain for AVISE CTD, which we commonly refer to as our average selling price,
or ASP. When I joined the company, we were in the midst of a pricing and coverage discussion with
CMS, our trailing twelve-month ASP sat at $285 at the end of 2022 and was in the process of moving
lower due to repricing by Medicare, which was expected to occur in January of 2023. The team here
at Exagen has worked extremely hard to not only make up for this headwind, but to further improve
our TTM ASP from 2022 levels. As we look back at 2023, we dramatically overhauled our revenue
cycle operations, changing personnel, processes and systems. We held claims in the first half of the
year in order to better manage filing deadlines with commercial payors and this allowed us to

improve our processes without sacrificing efficacy as the year went on. Our primary goal with
improving revenue cycle operations is not only to win individual appeals, but it has strategic
implications and specifically, we are working to create awareness at the payor level of who we are,
how our tests are critical to patient care and why it   s a financial benefit to be included in their suite
of covered services, all of which is included with each appeal. We are still in the infancy of our new
appeals efforts, which increased 162% in 2023 and have set ourselves up well for 2024 and beyond.
Improvement in our TTM ASP will be key in evaluating the success of our strategy and it   s a metric
we watch and report on consistently.

As part of our focus on revenue cycle operations, we needed effective documentation of the clinical
utility of each test ordered on a per patient basis to initiate an effective appeal effort. This necessitated
us to change the requirements for ordering an AVISE test, such that progress notes, specifically citing
the clinical presentation of the patient are needed. This can be cumbersome for office staff in the
clinic, which are evermore under constraints to operate efficiently, but are essential in communicating
effectively with payors and in pursuing adequate payment of our test. The net impact of these
changes has been what I expect to be a one-time reset of our test volume growth trajectory. While we
opened 2023 with consecutive quarters of test volume growth, we ended the year with consecutive
quarters of test volume more consistent with 2021/2022 performance. Your field-based sales team is
working diligently with each of our customers to find the most efficient and effective way to satisfy the
needs of insurers with minimal burden to the daily practice of rheumatologic care in their clinics.
This adjustment takes time, but we believe the clinical value gained in the use of AVISE CTD for
patients who have typically waited on average 6-years or more to arrive at a diagnosis will outweigh
the documentation needs we   ve now imposed. In 2024, I expect the growth at Exagen to be both a
combination of improving ASP paired with growth in test volume as we progress to a more profitable
and sustainable business model.
Additionally, this year we   ve substantially revamped our research and development efforts and believe
we are now better equipped to devote resources and capital to projects which will have improved
prospects of contributing to the success of Exagen in the long-term. From late 2022 to early 2023, we
set about a rigorous review of all pipeline efforts, specifically evaluating them against pre-set criteria.
We are focused on opportunities which best fit existing customer needs, as identified through
exhaustive voice of customer efforts. We have a very good understanding of where Rheumatologists
prefer additional information in their clinical practice, and we are working to develop these assets.
As a smaller esoteric diagnostic company, we will be successful in the long-term if we develop
proprietary offerings; we lack the infrastructure advantages of larger laboratories and therefore need
proprietary offerings with unique value propositions to operate effectively in the market. We are also
committed to charting out the evidence development pathway at time of undertaking an
opportunity. We have thought through how to prove, and what resources are likely to be required in
proving, clinical utility of an offering.
This has become an ever-increasing evidentiary threshold for payors, including Medicare. We plan
to have Medicare coverage and pricing prior to commercial launch, as it serves as a significant
anchor in private payor discussions, given the public nature of CMS   s processes and the fact that
most commercial insurers service some portion of managed Medicare patients and therefore are
required to adhere to coverage policies, when finalized. Lastly, and parallel to the importance of
clinical utility, we will have a concerted effort to establish guideline support for new products from
the very beginning. We believe that evaluating opportunities against these criteria substantially
reduces risk of poor long-term performance, but time will be needed to bear-out our beliefs.
Path to Profitability
In 2023, your company improved its current and long-term prospects of being a dominant
contributor to the autoimmune testing ecosystem. The team at Exagen worked extremely hard to
execute as quickly and effectively as possible in making Exagen a profitable organization, and real
progress was made. Our adjusted EBITDA, which is a reasonable approximation of cash needed to
operate the business on an annual basis, reduced by more than half in 2023 vs. 2022. With this
progress, your company continued to grow top line revenue, by just over 15% and delivered
marked improvement in TTM ASP. We are proud of these accomplishments which have pushed
our current operating runway into 2026 with our existing cash balance, but we are not satisfied
and will be working hard in 2024 to improve this further.
