ITEM 1.     BUSINESS

Overview

PART I

We  are  a  commercial-stage  medical  device  company  that  designs,  manufactures,  and  sells  real-time  high-definition  image-guided,  minimally
invasive catheter-based systems that are used by physicians to treat patients with peripheral artery disease (“PAD”). Patients with PAD have a build-up of
plaque in the arteries that supply blood to areas away from the heart, particularly the pelvis and legs. Our mission is to significantly improve the treatment
of vascular disease through the introduction of products based on our Lumivascular platform, the only intravascular real-time high-definition image-guided
system available in this market.

We  design,  manufacture,  and  sell  a  suite  of  products  in  the  United  States  and  select  international  markets.  We  are  located  in  Redwood  City,
California. Our current Lumivascular platform consists of products including our Lightbox imaging console, the Ocelot and Tigereye family of devices,
which are image-guided devices designed to allow physicians to penetrate a total blockage in an artery, known as a chronic total occlusion (“CTO”), and
the Pantheris family of catheters, our image-guided atherectomy catheters which are designed to allow physicians to precisely remove arterial plaque in
PAD patients.

We are in the process of developing CTO crossing devices to target the coronary CTO market. However, the market for medical devices in the
coronary  artery  disease  (“CAD”)  space  is  highly  competitive,  dynamic,  and  marked  by  rapid  and  substantial  technological  development  and  product
innovation and there is no guarantee that we will be successful in developing and commercializing any new CAD product. At this stage, we are working on
understanding market requirements, and initiated the development process for the new CAD product, which we anticipate will require additional expenses.

We obtained CE Marking for our original Ocelot product in September 2011 and received from the FDA 510(k) clearance in November 2012. We
received  510(k)  clearance  from  the  FDA  for  commercialization  of  Pantheris  in  October  2015.  We  also  received  an  additional  510(k)  clearance  for  an
enhanced version of Pantheris in March 2016 and commenced sales of Pantheris in the United States and select European countries promptly thereafter. In
May 2018, we received 510(k) clearance from the FDA for our current next-generation version of Pantheris. In April 2019, we received 510(k) clearance
from the FDA for our Pantheris Small Vessel (“SV”), a version of Pantheris targeting smaller vessels, and commenced sales in July 2019. In September
2020, we received 510(k) clearance of Tigereye, a next-generation CTO crossing system utilizing Avinger’s proprietary image-guided technology platform.
Tigereye is a product line extension of Avinger’s Ocelot family of image-guided CTO crossing catheters. In January 2022, we received 510(k) clearance
from the FDA for our Lightbox 3 imaging console, an advanced version of our Lightbox that allows for easy portability and offers significant reductions in
size, weight, and production cost in comparison to the incumbent version.

In  April  2023,  we  received  510(k)  clearance  from  the  FDA  for  Tigereye  Spinning  Tip  (“ST”),  a  next-generation  image-guided  CTO  crossing
system. Tigereye ST is a line extension of our Ocelot and Tigereye family of CTO crossing catheters. This new image-guided catheter incorporates design
upgrades  to  the  tip  configuration  and  catheter  shaft  to  increase  crossing  power  and  procedural  success  in  challenging  lesions,  as  well  as  design
enhancements for ease of image interpretation during the procedure. The low-profile Tigereye ST has a working length of 140 cm and 5 French sheath. We
initiated a limited launch of Tigereye ST in the second quarter of 2023 and subsequently expanded to full commercial availability within the United States
during the third quarter of 2023.

In June 2023, we received 510(k) clearance from the FDA for Pantheris Large Vessel (“LV”), a next generation image guided atherectomy system
for the treatment of larger vessels, such as the superficial femoral artery (“SFA”) and popliteal arteries. Pantheris LV is a line extension of our Pantheris and
Pantheris SV family of atherectomy products. This catheter offers higher speed plaque excision for efficient removal of challenging occlusive tissue and
multiple  features  to  streamline  and  simplify  user-operation,  including  enhanced  tissue  packing  and  removal,  a  radiopaque  gauge  to  measure  volume  of
plaque excised during the procedure, and enhanced guidewire management. We initiated a limited launch of the Pantheris LV during the third quarter of
2023 and expect to expand to full commercial availability within the United States around mid-year 2024.

Current treatments for PAD, including bypass surgery, can be costly and may result in complications, high levels of post-surgery pain, and lengthy
hospital stays and recovery times. Minimally invasive, or endovascular, treatments for PAD include stenting, angioplasty, and atherectomy, which is the use
of  a  catheter-based  device  for  the  removal  of  plaque.  These  treatments  all  have  limitations  in  their  safety  or  efficacy  profiles  and  frequently  result  in
recurrence of the disease, also known as restenosis. We believe one of the main contributing factors to high restenosis rates for PAD patients treated with
endovascular technologies is the amount of vascular injury that occurs during an intervention. Specifically, these treatments often disrupt the membrane
between the outermost layers of the artery, which is referred to as the external elastic lamina (“EEL”).

Table of Contents

We believe our Lumivascular platform is the only technology that offers radiation free, high-definition real-time visualization of the inside of the
artery during PAD treatment through the use of optical coherence tomography (“OCT”), a high resolution, light-based, radiation-free imaging technology.
Our  Lumivascular  platform  provides  physicians  with  high-definition  real-time  OCT  images  from  the  inside  of  an  artery,  and  we  believe  Ocelot  and
Pantheris  are  the  first  products  to  offer  intravascular  visualization  during  CTO  crossing  and  atherectomy,  respectively.  We  believe  this  approach  will
significantly improve patient outcomes by providing physicians with a clearer picture of the artery using radiation-free image guidance during treatment,
enabling them to better differentiate between plaque and healthy arterial structures. Our Lumivascular platform is designed to improve patient safety by
enabling physicians to direct treatment towards the plaque, while avoiding damage to healthy portions of the artery.

During  the  first  quarter  of  2015,  we  completed  enrollment  of  patients  in  VISION,  a  clinical  trial  designed  to  support  our  August  2015
510(k)  submission  to  the  FDA  for  our  Pantheris  atherectomy  device.  VISION  was  designed  to  evaluate  the  safety  and  efficacy  of  Pantheris  to  perform
atherectomy  using  intravascular  imaging  and  successfully  achieved  all  primary  and  secondary  safety  and  efficacy  endpoints.  We  believe  the  data  from
VISION allows us to demonstrate that avoiding damage to healthy arterial structures, and in particular disruption of the external elastic lamina, which is the
membrane between the outermost layers of the artery, reduces the likelihood of restenosis, or re-narrowing, of the diseased artery. Although the original
VISION study protocol was not designed to follow patients beyond six months, we worked with 18 of the VISION sites to re-solicit consent from previous
clinical trial patients in order for them to evaluate patient outcomes through 12 and 24 months following initial treatment. Data collection for the remaining
patients from participating sites was completed in May 2017, and we released the final 12- and 24-month results for a total of 89 patients in July 2017.

During the fourth quarter of 2017, we began enrolling patients in INSIGHT, a clinical trial designed to support a submission to the FDA to expand
the  indication  for  our  Pantheris  atherectomy  device  to  include  the  treatment  of  in-stent  restenosis.  Patient  enrollment  began  in  October  2017  and  was
completed in July 2021. Patient outcomes were evaluated at thirty days, six months and one year following treatment. In November 2021, we received
510(k) clearance from the FDA for this new clinical indication for treating in-stent restenosis with Pantheris using the data collected and analyzed from
INSIGHT.  We  expect  this  will  expand  our  addressable  market  for  Pantheris  to  include  a  high-incidence  disease  state  for  which  there  are  few  available
indicated or effective treatment options.

We are pursuing additional clinical data programs including a post-market study, IMAGE-BTK, that is designed to evaluate the safety and efficacy
of Pantheris SV in the treatment of PAD lesions below-the-knee. We completed patient enrollment in 2023. Patient outcomes are being evaluated at thirty
days, six months and one year following treatment. We expect this will bolster the application of Pantheris SV as a primary interventional tool to address
below-the-knee lesions for which there are few available effective treatment options.

We focus our direct sales force, marketing efforts and promotional activities on interventional cardiologists, vascular surgeons and interventional
radiologists. We also work on developing strong relationships with physicians and hospitals that we have identified as key opinion leaders. Although our
sales and marketing efforts are directed at these physicians because they are the primary users of our technology, we consider the hospitals and medical
centers where the procedure is performed to be our customers, as they typically are responsible for purchasing our products. We are designing additional
future  products  to  be  compatible  with  our  Lumivascular  platform,  which  we  expect  to  enhance  the  value  proposition  for  hospitals  to  invest  in  our
technology.  Pantheris  qualifies  for  existing  reimbursement  codes  currently  utilized  by  other  atherectomy  products,  further  facilitating  adoption  of  our
products.

We  have  assembled  a  team  with  extensive  medical  device  development  and  commercialization  experience  in  both  start-up  and  large,  multi-
national medical device companies. We assemble all of our catheter products at our manufacturing facility but certain critical processes, such as coating and
sterilization, are performed by outside vendors. Our Lightbox 3 imaging console is assembled through a qualified contract manufacturer. We expect our
current manufacturing facility in California, will be sufficient through at least 2024. We generated revenues of $10.1 million in 2021, $8.3 million in 2022
and  $7.7  million  in  2023.  Revenue  in  2020  was  adversely  affected  by  COVID-19  as  hospitals  deferred  elective  procedures,  which  among  other  things,
created unpredictability in case volume. This unpredictability created more volatility in our revenues which continued to adversely affect our business in
2021  and  to  a  lesser  extent,  in  2022.  The  decline  in  revenue  in  2022  and  2023  was  primarily  attributable  to  the  adverse  effects  of  staffing  shortages,
resource constraints on our customers, and the impact of a very competitive market for talent on the retention of our commercial team.

Lumivascular Platform Overview

Our  Lumivascular  platform  integrates  OCT  (optical  coherence  tomography)  visualization  with  interventional  devices  and  is  the  industry’s  only
system that provides radiation free, high definition real-time intravascular imaging simultaneously with treatment in PAD procedures. Our Lumivascular
platform consists of a capital component, Lightbox, and a variety of disposable catheter products, including the Ocelot, Tigereye and Pantheris family of
catheters.

Lightbox

Lightbox is our proprietary video imaging console, which enables the use of Lumivascular devices during PAD procedures. The console contains
an optical transceiver that transmits light into the artery through an optical fiber and displays a cross-sectional image of the vessel to the physician on a
high-definition monitor during the procedure.

Lightbox displays a cross-sectional view of the vessel, which provides physicians with detailed information about the orientation of the catheter
and the surrounding artery and plaque. Layered structures represent relatively healthy portions of the artery and non-layered structures represent the plaque
that is blocking blood flow in the artery. Navigational markers allow the physician to orient the catheter toward the treatment area, helping to avoid damage
to the healthy arterial structures during a procedure. Lightbox received FDA 510(k) clearance in November 2012 and CE Marking in Europe in September
2011.

In January 2022, we received 510(k) clearance from the FDA for our next generation Lightbox 3 imaging console, the Lightbox 3, a version of our
Lightbox  that  delivers  important  advancements  in  imaging,  portability  and  capability  in  comparison  to  the  incumbent  version.  Lightbox  3  incorporates
advanced  features,  including  an  advanced  solid-state  laser  for  enhanced  high-definition  OCT  imaging,  a  more  powerful  computing  platform,  and  a
redesigned software system with a highly intuitive user interface that emphasizes efficiency and ease-of-use into a significantly smaller size and weight
console. We initiated a limited launch of Lightbox 3 in the United States in the first quarter of 2022 and expanded to full commercial availability in the
subsequent quarter.

Pantheris

We believe Pantheris is the first atherectomy device to incorporate radiation free high-definition real-time OCT intravascular imaging to guide the
procedure.  Pantheris  may  be  used  alone  or  following  a  CTO  crossing  procedure  using  Ocelot  or  other  products.  Pantheris  is  a  single-use  product  and
provides physicians with the ability to see a cross-sectional view of the peripheral artery to guide the removal of blockages throughout the procedure. The
Pantheris device restores blood flow by shaving strips of plaque using a high-speed directional cutting mechanism that enables physicians to specifically
target the portion of the artery where the plaque resides while minimizing disruption to healthy arterial structures. The excised plaque is deposited, collected
and contained into the nosecone of the Pantheris device and removed from the artery within the device.

In October 2015, we received 510(k) clearance from the FDA for commercialization of Pantheris. We made modifications to Pantheris after the
completion of the VISION trial and commenced sales in the United States and select international markets following receipt of FDA approval for this initial
version of Pantheris in March 2016. We first received CE Marking for Pantheris in June 2015. We received CE Marking in December 2017 and 510(k)
clearance in May 2018 for a next-generation version of Pantheris, which includes new features and design improvements to the handle, shaft, balloon and
nosecone  of  the  device.  The  next-generation  Pantheris  atherectomy  device  is  currently  available  for  commercial  sale  in  the  United  States  and  select
international markets. All previous versions of Pantheris have been discontinued.

We  also  offer  a  line  extension  of  our  Pantheris  image-guided  atherectomy  platform,  Pantheris  SV,  a  lower  profile  version  of  Pantheris.  The
Pantheris  SV  has  a  smaller  diameter  and  longer  length  and  is  designed  for  use  in  smaller  vessels  2.0  to  4.0  millimeters  in  diameter.  We  received  CE
Marking in October 2018 and 510(k) clearance in April 2019 for this product and commenced sales in the United States in July 2019.

Another line extension of our Pantheris platform is Pantheris LV. The Pantheris LV has a larger diameter and shorter length than the Pantheris SV
and is designed for use in larger vessels 3.0 to 7.0 millimeters in diameter. We received 510(k) clearance for this product in June 2023 and commenced a
limited  commercial  launch  in  the  United  States  during  the  third  quarter  of  2023  and  expect  to  expand  to  full  commercial  availability  within  the  United
States around mid-year 2024.

Ocelot and Tigereye

Ocelot  is  the  first  CTO  crossing  catheter  to  incorporate  radiation  free  high-definition  real-time  OCT  intravascular  imaging,  which  allows
physicians to see the inside of a peripheral artery during a CTO crossing procedure. Physicians have traditionally relied solely on fluoroscopy and tactile
feedback to guide interventional catheters through complicated blockages. Ocelot allows physicians to accurately navigate through CTOs by utilizing the
OCT images to precisely guide the device through the arterial blockage, while minimizing disruption to the healthy arterial structures. A successful CTO
crossing and placement of a guidewire allows the physician to subsequently treat the vessel with a minimally invasive therapeutic device. We received CE
Marking for Ocelot in September 2011 and received FDA 510(k) clearance in November 2012.

We also offer Ocelot PIXL, a lower profile CTO crossing device for below-the-knee arteries and Ocelot MVRX, which offers a different tip design
for peripheral arteries above-the-knee. We received CE Marking for Ocelot PIXL in October 2012 and received FDA 510(k) clearance in December 2012.
We received FDA 510(k) clearance for Ocelot MVRX in December 2012.

Tigereye ST is another product line extension of our Ocelot family of image-guided CTO crossing devices. This new image-guided catheter has an
integrated  outer  spinning  tip  that  pairs  with  the  rotation  of  the  inner  tip  to  penetrate  challenging  blockages  and  CTO  caps.  Tigereye  ST  incorporates  an
advanced shaft design for pushability and torque response and a three-marker system, similar to Ocelot's, to facilitate consistent image interpretation across
the platform. We received 510(k) clearance for Tigereye ST April 2023.

Tigereye is a product line extension of our Ocelot family of image-guided CTO crossing devices. Its design elements include an upgrade of the
image capture rate to provide high definition, real-time intravascular video imaging similar to the Pantheris image-guided atherectomy system and a user-
controlled deflectable tip designed to assist in steerability across the blockage. We received CE Marking for Tigereye in December 2019 and received FDA
510(k) clearance in September 2020. We discontinued selling this product in light of the enhancements we made to this device with the next generation,
Tigereye ST.         

Clinical Development

We have conducted several clinical trials to evaluate the safety and efficacy of our products in both pre-market and post-market assessments. We
received FDA clearance for the Ocelot CTO crossing device in 2012, for the Pantheris device for atherectomy in peripheral arteries in October 2015 and
then in November 2021 for the indication for use of the Pantheris device to include treatment of in-stent restenosis following completion of clinical trials of
these devices.

CONNECT II (Ocelot)

Our clinical trial for Ocelot, known as CONNECT II, was a prospective, multi-center, non-randomized trial that evaluated the safety and efficacy
of Ocelot in crossing CTOs in arteries of the upper leg using OCT intravascular imaging. The CONNECT II trial enrolled 100 patients with CTOs at 13
centers in the United States and 2 centers in Europe. Patients were followed for 30 days post-procedure and an independent group of physicians verified the
results to confirm the primary efficacy and safety endpoints. Results from the CONNECT II trial demonstrated that Ocelot surpassed its primary efficacy
endpoint  by  successfully  crossing  the  CTO  in  97%  of  the  cases  following  unsuccessful  attempts  to  cross  with  standard  guidewire  techniques.  Ocelot
achieved these rates with 98% freedom from major adverse events (“MAEs”).

VISION (Pantheris)

VISION was our pivotal, non-randomized, prospective, single-arm trial to evaluate the safety and effectiveness of Pantheris across 20 sites within
the United States and Europe. The objective of the clinical trial was to demonstrate that Pantheris can be used to effectively remove plaque from diseased
lower extremity arteries while using on-board visualization as an adjunct to fluoroscopy. Two groups of patients were treated in VISION: (1) optional roll-
ins, which are typically the first two procedures at a site, and (2) the primary cohort, which are the analyzable group of patients. The data for these two
groups were reported separately in our 510(k) submission to the FDA. Based on final enrollment, the primary cohort included 130 patients. In March 2015,
we completed enrollment of patients in the VISION clinical trial and we submitted for 510(k) clearance from the FDA in August 2015. In October 2015, we
received 510(k) clearance from the FDA for commercialization of Pantheris. We made modifications to Pantheris subsequent to the completion of VISION
and received 510(k) clearance an enhanced version of Pantheris in March 2016, and received 510(k) clearance in May 2018 for a next-generation version of
Pantheris, which included new features and design improvements to the handle, shaft, balloon, and nose cone of the device as well as 510(k) clearance in
April 2019 for Pantheris SV, a lower profile Pantheris.

VISION’s primary efficacy endpoint required that at least 87% of lesions treated by physicians using Pantheris have a residual stenosis of less than
50%, as verified by an independent core laboratory. The primary safety endpoint required that less than 43% of patients experience an MAE through six-
month  follow-up  as  adjudicated  by  an  independent  Clinical  Events  Committee  (“CEC”).  MAEs  as  defined  in  VISION  included  cardiovascular-related
death,  unplanned  major  index  limb  amputation,  clinically  driven  target  lesion  revascularization,  or  TLR,  heart  attack,  clinically  significant  perforation,
dissection, embolus, and pseudoaneurysm. Results from the VISION trial demonstrated that Pantheris surpassed its primary efficacy and safety endpoints;
residual restenosis of less than 50% was achieved in 96.3% of lesions treated in the primary cohort, while MAEs were experienced in 16.6% of patients.

Final VISION trial data are summarized in the table below.

Although  not  mandated  by  the  FDA  to  support  the  market  clearance  of  Pantheris,  the  protocol  for  the  VISION  trial  allowed  for  routine
histopathological analysis of the tissue extracted by Pantheris to be conducted. This process allowed us to determine the amount of adventitia present in the
tissue,  which  in  turn  indicated  the  extent  to  which  the  external  elastic  lamina  had  been  disrupted  during  Pantheris  procedures.  We  completed
histopathological  analysis  on  tissue  from  129  patients  in  the  primary  cohort,  representing  162  lesions,  and  determined  that  the  average  percent  area  of
adventitia  in  the  total  excised  tissue  was  only  1.0%.  Research  shows  that  a  low  level  of  arterial  wall  disruption  correlates  to  lower  restenosis  rates  and
improved long-term outcomes for patients treated with Pantheris. The results of this histopathological analysis in conjunction with the primary safety and
efficacy endpoint data from the VISION trial were published in the Journal of Endovascular Therapy in 2017.

Although the original VISION study protocol was not designed to follow patients beyond six months, in 2016 we began working with 18 of the
VISION  sites  to  re-consent  patients  in  order  for  them  to  be  evaluated  for  patient  outcomes  through  12  and  24  months  following  initial  treatment.  Data
collection for patients from participating sites was completed in May 2017, and we released the final 12- and 24-month results for a total of 73 patients and
89 lesions in July 2017. The key metrics reported for this group were freedom from target lesion revascularization, or TLR, at 12 months and 24 months,
which were 82% and 74% by patient and 83% and 76% by lesion, respectively, based on Kaplan-Meier curve assessments.

INSIGHT (Pantheris)

The INSIGHT Trial was a prospective, global, single-arm, multi-center trial to evaluate the safety and effectiveness of Pantheris for treating in-
stent  restenosis  (“ISR”)  in  lower  extremity  arteries.  ISR  occurs  when  a  blocked  artery  previously  treated  with  a  stent  becomes  narrowed  again,  thereby
reducing  blood  flow.  Physicians  often  face  challenges  when  treating  ISR  both  in  terms  of  safety  and  efficacy.  From  a  safety  standpoint,  limitations  in
imaging techniques, such X-ray fluoroscopy, and the inability to control the directionality of other atherectomy devices create concerns about impacting the
integrity  of  the  stent  during  the  procedure.  In  terms  of  efficacy,  current  therapies  for  in-stent  restenosis,  such  as  balloon  angioplasty,  have  high  rates  of
recurrent narrowing within stents.

The INSIGHT trial enrolled 97 patients at sites in the United States and Europe. Patient enrollment began in October 2017 and concluded in July

2021. Patients were evaluated at thirty days, six months and one year following treatment.

The  primary  safety  endpoint  was  defined  as  freedom  from  a  composite  of  MAEs  through  30  days  after  the  procedure,  as  adjudicated  by  an
independent CEC. The primary effectiveness endpoint was technical success, defined as the percent of target lesions that have a residual diameter stenosis ≤
50% after use of the Pantheris device alone, as assessed by an independent angiographic core laboratory. The secondary safety endpoint was absence of
new  or  worsening  stent  fracture  following  use  of  the  Pantheris  catheter.  A  secondary  powered  effectiveness  endpoint  was  freedom  from  target  lesion
revascularization  (“TLR”)  at  6  months  following  the  index  procedure.  Additional  secondary  effectiveness  included  procedural  success,  defined  as  the
percent of target lesions that have residual diameter stenosis ≤ 30% post-Pantheris and any other adjunctive therapy, as determined by an independent core
lab, and changes in Ankle- Brachial Index (“ABI”), and Rutherford Classes at 30 days and 6 months after the procedure in relation to the measurements
prior to the procedure.

The subjects enrolled in the INSIGHT trial presented with documented symptomatic in-stent restenosis (stenosis >70% by visual estimation) and
met all eligibility criteria. The target in-stent restenotic lesion had to be located in vessels with diameters of > 3 mm and < 7 mm and were not to exceed 30
cm in length. Subjects were followed through 30 days and six months post-procedure for purposes of the FDA submission to expand the indication for use
statement. The clinical data for 97 subjects enrolled that reported for clinic visits 30 days and 85 subjects who reported for clinic visits 6 months after the
index procedure were analyzed.

The  primary  safety  endpoint  was  defined  as  freedom  from  a  composite  of  MAEs  through  30  days  after  the  procedure,  as  adjudicated  by  an
independent CEC. Only 3 subjects (accounting for 3%) experienced a MAE, with 97% of subjects free from MAEs within 30 days. With only 3% subjects
reporting an MAE and a 95% one-sided upper confidence bound of 6.5%, the primary safety performance goal of MAEs occurring in < 20% of subjects
was met.

The  secondary  safety  endpoint  was  absence  of  new  or  worsening  stent  fracture  following  use  of  the  Pantheris  catheter.  Only  one  (1)  catheter
inadvertently made contact with a stent during the 97 procedures, a rate of 1%. This endpoint was not established with a sample size requirement, so this
performance goal was met not only due to its extremely low incidence rate but also by the experience that after re-training the one physician who had this
event on the use of real-time optical coherence tomography imaging during the procedure the physician completed 12 subsequent cases with no further
events.

The  primary  effectiveness  endpoint  of  this  study  was  technical  success,  defined  as  the  percent  of  target  lesions  that  have  a  residual  diameter
stenosis ≤ 50% after use of the Pantheris device alone, as assessed by an independent angiographic core laboratory. In this analysis, 86 out of 97 (89%)
subjects  had  <50%  residual  stenosis  following  use  of  the  Pantheris  catheter  alone,  with  a  95%  one-sided  upper  confidence  bound  of  95%  and  a  lower
confidence bound of 82%, which met the adjusted performance goal of > 79%.

A secondary powered effectiveness endpoint was freedom from TLR at 6 months following the index procedure. The freedom from TLR of the 85
subjects that have completed their 6-month follow-up visits after the index procedure was 93% (79/85), with a 95% one-sided upper confidence bound of
98% and a lower bound of 87%, which met the performance goal of > 61%.

Additional secondary effectiveness included procedural success, defined as the percent of target lesions that have residual diameter stenosis ≤ 30%
post-Pantheris and any other adjunctive therapy, as determined by an independent core lab, and changes in Ankle- Brachial Index (ABI), and Rutherford
Classes at 30 days and 6 months after the procedure in relation to the measurements prior to the procedure.

Procedural success was determined if the residual diameter stenosis was < 30% following adjunctive treatment. In this cohort 78 of the 97 subjects

(80%) were determined to have a residual stenosis < 30% following review of angiograms by the core lab, with a mean stenosis of 15% ±10.1%.

Table of Contents

The ABI measures improved 39% from baseline by the time of the 6-month visit and the Rutherford Classification measures improved by 71% at

the same time.

Adjunctive devices used in the procedure were primarily balloons (83%), with balloon angioplasty followed by placement of a stent occurring in

13% of the cases, and no adjunctive treatment provided in 4% of the procedures.

The results from the INSIGHT trial demonstrated that the Pantheris catheter is safe and effective when used to address in-stent restenosis. The
study endpoints achieved the effectiveness performance goals while demonstrating a strong safety profile indicating that the Pantheris catheter can be used
to safely excise tissue from occluded vascular stents with precision. The study results also demonstrate extremely low, acute device-related adverse events.

A 510(k) application to the FDA was submitted in June 2021 and we received clearance to add ISR treatment to the indication for use for the

Pantheris catheter in November 2021.

Other Studies

We  are  pursuing  additional  clinical  data  programs,  including  a  post-market  study,  IMAGE-BTK,  that  is  designed  to  evaluate  the  safety  and
efficacy of Pantheris SV in the treatment of PAD lesions below-the-knee. Enrollment has been completed; patient outcomes are being evaluated at thirty
days, six months and one year following treatment. We expect this will bolster the application of Pantheris SV as a primary interventional tool to address
below-the-knee lesions for which there are few available effective treatment options.

Sales and Marketing

We focus our sales and marketing efforts primarily on the approximately 10,000 interventional cardiologists, vascular surgeons and interventional
radiologists in the United States that are potential users of our Lumivascular platform products. Our marketing efforts are focused on developing strong
relationships with physicians and hospitals that we have identified as key opinion leaders based on their knowledge of our products, clinical expertise and
reputation.  We  also  use  continuing  medical  education  programs  and  other  opportunities  to  train  interventional  cardiologists,  vascular  surgeons,  and
interventional radiologists in the use of our Lumivascular platform products and educate them as to the benefits of our products as compared to alternative
procedures such as angioplasty, stenting, bypass surgery or other atherectomy procedures. In addition, we work with physicians to help them develop their
practices and with hospitals to market themselves as centers of excellence in PAD treatment by making our products available to physicians for treating
patients.

Our  sales  team  currently  consists  of  a  Chief  Commercial  Officer,  Vice  President,  Regional  Directors,  Territory  Sales  Managers,  Clinical
Specialists, and one Vice President of International Sales. Territory Sales Managers are responsible for all product sales, which include disposable devices
and  sale  and  service  of  our  Lightbox  console,  while  Clinical  Specialists  are  primarily  responsible  for  case  coverage  and  account  support.  We  have  an
extensive hands-on sales training program, focused on our technologies, Lumivascular image interpretation, case management, sales processes, sales tools
and implementing our sales and marketing programs and compliance with applicable federal and state laws and regulations. Our sales team is supported by
our marketing team, which focuses primarily on clinical training and education, marketing communications and product management. We have partnered
with a third-party field service firm for the installation, service and maintenance of our Lightbox consoles.

For the year ended December 31, 2023, we had one customer that represented approximately 17% of revenues. For the year ended December 31,

2022, we had one customer that represented approximately 14% of revenues.

Competition

The  medical  device  industry  is  highly  competitive,  subject  to  rapid  change  and  significantly  affected  by  new  product  introductions,  results  of
clinical research, reimbursement dynamics, corporate combinations and other factors relating to our industry. Because of the market opportunity and the
high  growth  potential  of  the  PAD  treatment  market,  competitors  and  potential  competitors  have  historically  dedicated,  and  will  continue  to  dedicate,
significant resources to aggressively develop and commercialize their products.

10

 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

Our products compete with a variety of products or devices for the treatment of PAD, including other CTO crossing devices, stents, balloons and
atherectomy  catheters,  as  well  as  products  used  in  vascular  surgery.  Large  competitors  in  the  CTO  crossing,  stent  and  balloon  market  segments  include
Abbott  Laboratories,  AngioDynamics,  Becton  Dickinson,  Boston  Scientific,  Cardinal  Health,  Cook  Medical,  Medtronic  and  Philips.  Competitors  in  the
atherectomy  market  include  AngioDynamics,  Boston  Scientific,  Cardiovascular  Systems,  Medtronic  and  Philips.  Some  competitors  have  attempted  to
combine  intravascular  imaging  with  atherectomy  and  although  we  are  not  aware  of  any  active  initiatives  in  this  area,  these  and  other  companies  may
attempt to incorporate on-board visualization into their products in the future or may have ongoing programs of which we are not aware. Other competitors
include  pharmaceutical  companies  that  manufacture  drugs  for  the  treatment  of  symptoms  associated  with  mild  to  moderate  PAD  and  companies  that
provide products used by surgeons in peripheral and coronary bypass procedures. These competitors and other companies may introduce new products that
compete with our solution.

Many of our competitors have substantially greater financial, manufacturing, marketing and technical resources than we do. Furthermore, many of
our competitors have well-established brands, widespread distribution channels and broader product offerings, and have established stronger and deeper
relationships with target customers.

To compete effectively, we have to demonstrate that our products are attractive alternatives to other devices and treatments on the basis of:

● procedural safety and efficacy;

● acute and long-term outcomes;

● ease of use and procedure time;

● third-party reimbursement;

● size, effectiveness, and productivity of sales force;

● radiation exposure for physicians, hospital staff and patients; and

● price.

Intellectual property

In order to remain competitive, we must develop and maintain protection of the proprietary aspects of our technologies. We rely on a combination

of patents, copyrights, trademarks, trade secret laws and confidentiality and invention assignment agreements to protect our intellectual property rights.

It is our policy to require our employees, consultants, contractors, outside scientific collaborators and other advisors to execute non-disclosure and
assignment of invention agreements on commencement of their employment or engagement. Agreements with our employees also forbid them from using
the proprietary rights of third parties in their work for us. We also require confidentiality or material transfer agreements from third parties that receive our
confidential data or materials.

As of December 31, 2023, we held 64 issued and allowed U.S. patents, 1 U.S. pending provisional application, 18 U.S. utility patent applications
and  3  PCT  applications  pending.  As  of  December  31,  2023,  we  also  had  83  issued  and  allowed  patents  from  outside  of  the  United  States.  As  of
December 31, 2023, we had 22 pending patent applications outside of the United States, including in Australia, Canada, China, Europe, India, Japan and
Mexico. As we continue to research and develop our products and technology, we intend to file additional U.S. and foreign patent applications related to the
design, manufacture and therapeutic uses of our devices. Our issued patents expire between the years 2028 and 2040.

Our patent applications may not result in issued patents and our patents may not be sufficiently broad to protect our technology. Any patents issued
to  us  may  be  challenged  by  third  parties  as  being  invalid,  or  third  parties  may  independently  develop  similar  or  competing  technology  that  avoids  our
patents. The laws of certain foreign countries do not protect our intellectual property rights to the same extent as do the laws of the United States.

As of December 31, 2023, we held six registered U.S. trademarks. In Europe, we hold one registered trademark. In the United Kingdom, we hold
one registered trademark. In addition, we held one International Registration under the Madrid Protocol with granted extensions to China, Europe, Japan,
and Korea (reflected in the one European registrations noted above).

Research and Development

Our ongoing research and development activities are primarily focused on improving and enhancing our Lumivascular platform, specifically our
core competency of integrating OCT intravascular imaging onto therapeutic catheters. Our research objectives target areas of unmet clinical need, increase
the utility of the Lumivascular platform and adoption of our products by healthcare providers.

● Product line improvements and extensions. We are developing improvements to our Lumivascular platform, including additional catheters for use
in different clinical applications. For example, we are developing next-generation CTO crossing devices to target both the peripheral and coronary
CTO markets.

● Additional treatment indications. We intend to seek additional regulatory clearances from FDA to expand the indications for which our products

can be marketed. This includes both expanding the marketed indications for our current products, as well as development of new products.

● Improved software and user interface. We intend to further develop our software to provide more information and control to our end users during a

procedure. We use physician and staff feedback to improve the features and user functionality of our Lumivascular platform

In addition to our internal team, we retain third-party contractors from time to time to provide us with assistance on specialized projects. We also

work closely with experts in the medical community to supplement our internal research and development resources.

Manufacturing

All of our products are manufactured in-house using components and sub-assemblies fabricated both at our facility in Redwood City, California
and by key qualified outside vendors. We assemble all of our finished catheter products at our manufacturing facility but certain critical processes such as
coating and sterilization are done by specialized outside vendors. We expect our current manufacturing facility will be sufficient through at least 2024.

Order quantities and lead times for components purchased from outside suppliers are based on our forecasts derived from historical demand and
anticipated future demand. Lead times for components may vary significantly depending on the size of the order, time required to fabricate and test the
components, specific supplier requirements and current market demand for the components and subassemblies. To date, we have experienced some delays
in  obtaining  some  of  our  components  and  subassemblies.  Any  significant  delay  or  interruption  in  our  supply  chain  could  impair  our  ability  to  meet  the
demands of our customers and could harm our business.

We rely on single and limited source suppliers for several of our components and sub-assemblies. For example, we rely on single vendors for our
optical fiber, coating and drive cables that are key components of our catheters, and we rely on single vendors for our laser and data acquisition card that are
key  components  of  our  Lightbox,  as  well  as  assembly  of  our  Lightbox  3.  These  components  are  critical  to  our  products  and  there  are  relatively  few
alternative sources of supply for them. Identifying and qualifying additional or replacement suppliers for any of the components used in our products could
involve significant time and cost. Any supply or service interruption from our vendors or failure to obtain additional vendors for any of the components or
services used to manufacture our products would limit our ability to manufacture our products and could therefore harm our business, financial condition
and  results  of  operations.  We  assess  supply  chain  risk  on  an  ongoing  basis  and  take  appropriate  actions  as  needed,  including  identifying  &  qualifying
second source suppliers.

Our manufacturing operations are subject to regulatory requirements of 21 CFR part 820 of the Federal Food, Drug and Cosmetic Act, or FFDCA;
the  Quality  System  Regulation,  or  QSR,  for  medical  devices  sold  in  the  United  States,  which  is  enforced  by  FDA;  the  Medical  Devices  Directive
93/42/EEC, and EU-MDD to EU-MDR Transition provisions, which are both currently required for doing business in the European Union; and applicable
requirements  relating  to  the  environment,  waste  management  and  health  and  safety  matters,  including  measures  relating  to  the  release,  use,  storage,
treatment, transportation, discharge, disposal and remediation of hazardous substances, and the sale, labeling, collection, recycling, treatment and disposal
of products containing hazardous substances. We cannot ensure that we will not incur material costs or liability in connection with our operations, or that
our past or future operations will not result in claims by or injury to employees or the public.

We  have  registered  with  FDA  as  a  medical  device  manufacturer  and  have  obtained  a  manufacturing  license  from  the  California  Department  of
Public Health, or CDPH. We and our component suppliers are required to manufacture our products in compliance with FDA’s QSR in 21 CFR part 820 of
the  FFDCA.  The  QSR  regulates  extensively  the  methods  and  documentation  of  the  design,  testing,  control,  manufacturing,  labeling,  quality  assurance,
packaging, storage and shipping of our products. FDA enforces the QSR through periodic unannounced inspections that may include the manufacturing
facilities of our subcontractors. In 2019, 2020 and 2021, BSI conducted multiple routine audits including surveillance audit, Microbiology audit, a MDSAP
re-certification audit and an unannounced audit in September 2019. Our Quality System has undergone more than 20 external audits by third parties and
regulatory authorities since 2009. We were audited in March 2022 as part of ISO 13485:2016 & MDSAP re-certification. The audit was conducted by BSI
at the behest of US-FDA. No major non-conformances were identified. Non-conformances identified in the audits have been addressed via Avinger’s CAPA
system and are being reviewed by our notified body for closure. Most recently, we were audited in January 2023 by BSI as part of our annual surveillance
for ISO 13485, EU-MDD, MDR Transitional provisions & MDSAP requirements. This audit did not identify any non-conformances.

Our  failure  or  the  failure  of  our  component  suppliers  to  maintain  compliance  with  the  QSR  requirements  could  result  in  the  shutdown  of  our
manufacturing operations or the recall of our products, which would harm our business. In the event that one of our suppliers fails to maintain compliance
with our or governmental quality requirements, we may have to qualify a new supplier and could experience manufacturing delays as a result. We have
opted to maintain quality assurance and quality management certifications to enable us to market our products in the member states of the European Union,
the European Free Trade Association and countries which have entered into Mutual Recognition Agreements with the European Union. Our Redwood City
facilities  meet  the  requirements  set  forth  by  ISO  13485:2016  Medical  devices—Quality  management  systems—Requirements  for  regulatory  purposes,
MDD 93/42/EEC European Union Council Medical Device Directive and EU-MDR 2017/745 transitional provisions. We are actively engaged with our
notified body to obtain EU-MDR certification for our current products that were part of our application in 2021. New products we have launched in US
starting in 2021 will be submitted for review for European approval under EU-MDR once certification is complete.

Government Regulation

In general, medical device companies must navigate a challenging regulatory environment. In the United States the FDA regulates the medical
device  market  to  ensure  the  safety  and  efficacy  of  these  products.  The  FDA  allows  two  primary  pathways  for  a  medical  device  to  gain  approval  for
commercialization:  (i)  a  pre-market  notification  or  510(k)  submission  based  upon  being  equivalent  to  a  device  already  in  commercial  distribution  (a
predicate device) or (ii) a pre-market approval (“PMA”). A completely novel product must go through the more rigorous PMA process if it cannot receive
authorization through a 510(k) submission. The FDA has established three different classes of medical devices that indicate the level of risk associated with
using a device and consequent degree of regulatory controls needed to govern its safety and efficacy. Class I and Class II devices are considered to have
minimal risk to the user. Some Class I and almost all Class II devices gain clearance for commercial distribution following review of an application to the
FDA,  generally  known  as  the  510(k)  process.  The  devices  regarded  as  the  highest  risk  by  the  FDA  are  designated  Class  III  and  generally  require  the
submission of a PMA application for approval prior to commercialization. Class III devices generally include life-sustaining, life-supporting, or implantable
devices or devices without a known predicate technology already approved by the FDA.

The 510(k) clearance path can be significantly less time-consuming and less arduous than the PMA path, making this route generally preferable
for a medical device company. A 510(k) application must include documentation that its device is substantially equivalent to a technology already cleared
through a 510(k) or in distribution before May 28, 1976, and for which the FDA has not required a PMA submission. The FDA has 90 days from the date
of the pre-market equivalence acceptance to authorize or decline commercial distribution of the device. However, similar to the PMA process, clearance
may take longer than this three-month window, as the FDA can request additional data to support the submission. If the FDA resolves that the product is
not substantially equivalent to a predicate device, then the device acquires a Class III designation, and a PMA must be approved before the device can be
commercialized.  All  of  our  currently  marketed  products  have  received  commercial  clearance  and  associated  indications  for  use  through  the
510(k) regulatory pathway, some with the support of clinical data.

After  a  device  receives  510(k)  clearance,  any  modification  that  could  significantly  affect  its  safety  or  effectiveness,  or  that  would  constitute  a
change in its intended use, requires an additional 510(k) submission and clearance before the modified device can be commercialized. The FDA allows
each manufacturer to make this determination initially, but the FDA can review any such decision and can disagree with the manufacturer’s determination.
If the FDA disagrees with the determination not to seek a new 510(k) clearance or PMA the FDA may retroactively require a new 510(k) clearance or pre-
market approval for the modified device. The FDA could also require a manufacturer to cease marketing and distribution of the modified device and/or
recall the modified device until 510(k) clearance or PMA approval is obtained. Also, in these circumstances, a manufacturer may be subject to significant
regulatory fines, penalties, and enforcement actions.

13

 
 
 
 
 
 
 
Table of Contents

A PMA application must include reasonable scientific and clinical data that demonstrates the device is safe and effective for the intended uses and
indications being sought. The application must also include preclinical testing, technical, manufacturing, and labeling information. If the FDA determines
the  application  can  undergo  substantive  review,  it  has  180  days  to  review  the  submission,  but  it  can  typically  take  longer  (up  to  several  years)  as  this
regulatory  body  can  request  additional  information  or  clarifications.  The  FDA  may  also  impose  additional  regulatory  hurdles  for  a  PMA,  including  the
institution of an advisory panel of experts to assess the application or provide recommendations as to whether to approve the device. Although the FDA in
the end approves or disapproves the device, in nearly all cases the FDA follows the recommendation from the advisory panel. As part of this process, the
FDA will usually inspect the manufacturing facilities and operations prior to approval to verify compliance with quality control regulations. Significant
changes in the manufacturing of a device, or changes in the intended use, indications and labeling or design of a product require new PMA applications or
PMA supplements for a product originally approved under a PMA. This creates substantial regulatory risk for devices undergoing the PMA route.

Pervasive and Continuing Regulation

After a device is placed on the market, numerous regulatory requirements continue to apply. These include:

  ● the FDA’s quality system regulation (“QSR”) that requires manufacturers, including third-party manufacturers, to follow stringent design, testing,

control, documentation, and other quality assurance procedures during all aspects of the manufacturing process;

  ● labeling regulations and FDA prohibitions against the promotion of products for uncleared, unapproved or off-label uses;

  ● clearance or approval of product modifications that could significantly affect safety or efficacy or that would constitute a major change in intended

use;

  ● medical device reporting, or MDR, regulations, that require manufacturers report to the FDA if their device may have caused or contributed to a
death or serious injury or malfunctioned in a way that would likely cause or contribute to a death or serious injury if the malfunction were to recur;
and

  ● post-market surveillance regulations, which apply when necessary to protect the public health or to provide additional safety and effectiveness data

for the device.

We are registered with the FDA as a medical device manufacturer and have obtained a manufacturing license from the CDPH. The FDA has broad
post-market  and  regulatory  enforcement  powers.  We  are  subject  to  unannounced  inspections  by  the  FDA  and  the  Food  and  Drug  Branch  of  CDPH  to
determine our compliance with the QSR and other regulations, and these inspections may include the manufacturing facilities of our suppliers. Our current
facility has been inspected by the FDA in 2009, 2011 and 2013, and two, three and zero observations, respectively, were noted during those inspections. In
the  latest  FDA  audit  in  2013,  there  were  no  observations  that  involved  a  material  violation  of  regulatory  requirements,  and  no  non-conformances  were
noted. Our responses to the observations noted in 2009 and 2011 were accepted by the FDA, and we believe that we are in substantial compliance with the
QSR. BSI, our European Notified Body, inspected our facility several times between 2010 and 2015 and found zero non-conformances. BSI conducted four
external audits in 2016 and zero non-conformances were found in all except for one audit, for which four minor non-conformances were found. In 2016, we
joined  the  medical  device-single  audit  program,  or  MDSAP  that  permits  audits  by  our  Notified  Body  to  substitute  for  routine  FDA  inspections.  Our
Notified Body audit performed in January 2017 resulted in zero non-conformances and an unannounced audit in September 2019, noted only two minor
non-conformances, that were addressed promptly and resolved. In 2019, 2020 and 2021, BSI conducted multiple routine audits including surveillance audit,
a  Microbiology  audit,  a  MDSAP  re-certification  audit  and  an  unannounced  audit  in  September  2019.  Our  quality  system  has  undergone  more  than  20
external audits by third-party and regulatory authorities since 2009. Most recently, we were audited in March 2022 as part of ISO 13485:2016 & MDSAP
re-certification.  The  audit  was  conducted  by  BSI  at  the  behest  of  the  FDA.  No  major  non-conformances  were  identified.  Minor  non-conformances
identified in the audits have been addressed via Avinger’s CAPA system and are being reviewed by our notified body for closure. As of the date of this
filing, we have no outstanding unresolved major non-conformances or findings pending with any regulatory body.

Failure  to  comply  with  applicable  regulatory  requirements  can  result  in  enforcement  action  by  FDA,  which  may  include  any  of  the  following

sanctions:

● warning letters, adverse publicity, fines, injunctions, consent decrees and civil penalties;

● repair, replacement, refunds, recall or seizure of our products;

● operating restrictions, partial suspension or total shutdown of production;

● refusing our requests for 510(k) clearance or pre-market approval of new products, new intended uses or modifications to existing products;

● withdrawing 510(k) clearance or pre-market approvals that have already been granted; and

● criminal prosecution.

Regulatory System for Medical Devices in Europe

The system of regulating medical devices operates by way of a certification for each medical device. Each certificated device is given CE marking
that  shows  the  device  has  a  Certificat  de  Conformité.  There  are  national  bodies  known  as  Competent  Authorities  in  each  member  state  in  the  EU  that
oversee the implementation of the EU’s medical device directive, or MDD, within its jurisdiction. The means of achieving the requirements for CE marking
varies according to the nature of the device. Devices are classified in accordance with their perceived risks, similarly to the U.S. system. The class of a
product  determines  the  requirements  to  be  fulfilled  before  CE  marking  can  be  placed  on  a  product,  known  as  a  conformity  assessment.  Currently
conformity assessments for our products are carried out as required by the MDD. Each member state can appoint Notified Bodies within its jurisdiction. If a
Notified Body of one member state has issued a Certificat de Conformité, the device can be distributed throughout the European Union without further
conformance tests being required by other member states.

In March 2019, we successfully transferred all current product certificates from BSI-UK to BSI-Netherlands in anticipation of the UK leaving the
European  Union.  Our  products  currently  with  CE  marking  are  distributed  in  the  EU,  subject  to  the  EU’s  medical  devices  directive,  or  MDD  with
certification renewed in May 2021. In May 2021, we successfully extended the validity of the MDD certificates by 3-years, which will provide certification
until we fully certify to the new EU-MDR, expected to become effective after calendar year 2027. We have made significant progress towards achieving
MDR  certification,  however,  the  certification  process  is  ongoing  and  we  expect  to  obtain  certification  in  the  near  term.  Until  such  time  as  we  are  fully
certified to EU MDR, we will be highly limited in our ability to make significant product changes to existing design and intended purposes of products (for
distribution in the EU only) and/or will be unable to launch new products in the EU. Such limitations could harm our business, financial condition, and
operating results.

Federal, State and Foreign Fraud and Abuse Laws

Because  of  the  significant  federal  funding  involved  in  Medicare  and  Medicaid,  Congress  and  the  states  have  enacted,  and  actively  enforce,  a
number of laws to eliminate fraud and abuse in federal healthcare programs. Our business is subject to compliance with these laws. In March 2010, the
Patient Protection and Affordable Care Act, as amended by the Healthcare and Education Affordability Reconciliation Act, which we refer to collectively
as the Affordable Care Act, was enacted in the United States. The provisions of the Affordable Care Act are effective on various dates. The Affordable Care
Act expands the government’s investigative and enforcement authority and increases the penalties for fraud and abuse, including amendments to both the
Anti-Kickback  Statute  and  the  False  Claims  Act,  to  make  it  easier  to  bring  suit  under  these  statutes.  The  Affordable  Care  Act  also  allocates  additional
resources  and  tools  for  the  government  to  police  healthcare  fraud,  with  expanded  subpoena  power  for  HHS,  additional  funding  to  investigate  fraud  and
abuse across the healthcare system and expanded use of recovery audit contractors for enforcement.

Anti-Kickback Statutes.        The  federal  Anti-Kickback  Statute  prohibits  persons  from  knowingly  and  willfully  soliciting,  offering,  receiving  or
providing remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual, or the furnishing or arranging for a good or
service, for which payment may be made under a federal healthcare program such as Medicare or Medicaid. Violation of the Anti-Kickback Statue is a
criminal  felony,  and  can  result  in  criminal  sanctions,  civil  penalties,  enforcement  under  the  False  Claims  Act,  and  exclusion  from  federal  healthcare
programs.

The definition of “remuneration” has been broadly interpreted to include anything of value, including, for example, gifts, certain discounts, the
furnishing  of  free  supplies,  equipment  or  services,  credit  arrangements,  payment  of  cash  and  waivers  of  payments.  Several  courts  have  interpreted  the
statute’s intent requirement to mean that if any one purpose of an arrangement involving remuneration is to induce referrals of federal healthcare covered
businesses, the statute has been violated. Penalties for violations include criminal penalties and civil sanctions such as fines, imprisonment and possible
exclusion from Medicare, Medicaid and other federal healthcare programs. In addition, some kickback allegations have been claimed to violate the Federal
False Claims Act, discussed in more detail below.

The  Anti-Kickback  Statute  is  broad  and  prohibits  many  arrangements  and  practices  that  are  otherwise  lawful  in  businesses  outside  of  the
healthcare  industry.  Recognizing  that  the  Anti-Kickback  Statute  is  broad  and  may  technically  prohibit  many  innocuous  or  beneficial  arrangements,
Congress authorized the Office of Inspector General, or OIG, of HHS to issue a series of regulations known as “safe harbors.” These safe harbors set forth
provisions that, if all their applicable requirements are met, will assure healthcare providers and other parties that they will not be prosecuted under the
Anti-Kickback  Statute.  The  failure  of  a  transaction  or  arrangement  to  fit  precisely  within  one  or  more  safe  harbors  does  not  necessarily  mean  that  it  is
illegal or that prosecution will be pursued. However, conduct and business arrangements that do not fully satisfy an applicable safe harbor may result in
increased scrutiny by government enforcement authorities such as OIG.

Many states have adopted laws similar to the Anti-Kickback Statute. Some of these state prohibitions apply to referral of recipients for healthcare

items or services reimbursed by any source, not only the Medicare and Medicaid programs.

Government  officials  have  focused  their  enforcement  efforts  on  the  marketing  of  healthcare  services  and  products,  among  other  activities,  and
recently  have  brought  cases  against  companies,  and  certain  individual  sales,  marketing  and  executive  personnel,  for  allegedly  offering  unlawful
inducements to potential or existing customers in an attempt to procure their business.

Federal False Claims Act.    Another development affecting the healthcare industry is the increased use of the federal False Claims Act by federal
prosecutors, and in particular, action brought pursuant to the False Claims Act’s “whistleblower” or “qui tam” provisions. The False Claims Act imposes
liability on any person or entity that, among other things, knowingly presents, or causes to be presented, a false or fraudulent claim for payment by a federal
healthcare program. The qui tam provisions of the False Claims Act allow a private individual to bring actions on behalf of the federal government alleging
that the defendant has violated the False Claims Act and to share in any monetary recovery. In recent years, the number of suits brought against healthcare
providers by private individuals has increased substantially. In addition, various states have enacted false claims laws analogous to the False Claims Act,
and many of these state laws apply where a claim is submitted to any third-party payor and not just a federal healthcare program.

When an entity is determined to have violated the False Claims Act, it may be required to pay up to three times the actual damages sustained by
the government, plus civil penalties of between $11,665-$23,331 for each separate instance of false claim. As part of any settlement, the government may
ask  the  entity  to  enter  into  a  corporate  integrity  agreement,  which  imposes  certain  compliance,  certification,  and  reporting  obligations.  There  are  many
potential bases for liability under the False Claims Act. Liability arises, primarily, when an entity knowingly submits, or causes another to submit, a false
claim for reimbursement to the federal government. The federal government has used the False Claims Act to assert liability on the basis of inadequate
care,  kickbacks  and  other  improper  referrals,  and  improper  use  of  Medicare  numbers  when  detailing  the  provider  of  services,  in  addition  to  the  more
predictable allegations as to misrepresentations with respect to the services rendered. In addition, the federal government has prosecuted companies under
the  False  Claims  Act  in  connection  with  off-label  promotion  of  products.  Our  future  activities  relating  to  the  reporting  of  wholesale  or  estimated  retail
prices of our products, the reporting of discount and rebate information and other information affecting federal, state, and third-party reimbursement of our
products and the sale and marketing of our products may be subject to scrutiny under these laws.

While  we  are  unaware  of  any  current  matters,  we  are  unable  to  predict  whether  we  will  be  subject  to  actions  under  the  False  Claims  Act  or  a
similar state law, or the impact of such actions. However, the costs of defending such claims, as well as any sanctions imposed, could significantly affect
our financial performance.

The Sunshine Act.    The Physician Payment Sunshine Act, or the Sunshine Act, which was enacted as part of the Affordable Care Act, requires all
United States manufacturers of a prescription drug, device, biologic or other medical supply that has been approved or cleared by the FDA, and is available
for coverage by Medicare, Medicaid or the Children’s Health Insurance Program to report annually to the Secretary of HHS: (i) payments or other transfers
of value made by that entity, or by a third-party as directed by that entity, to physicians and teaching hospitals or to third parties on behalf of physicians or
teaching hospitals; and (ii) physician ownership and investment interests in the drug and device manufacturing entity. The payments required to be reported
include the cost of meals provided to a physician, travel reimbursements and other transfers of value, including those provided as part of contracted services
such as speaker programs, advisory boards, consultation services and clinical trial services. Failure to comply with the reporting requirements can result in
significant civil monetary penalties ranging from $1,000 to $10,000 for each payment or other transfer of value that is not reported (up to a maximum per
annual  report  of  $150,000)  and  from  $10,000  to  $100,000  for  each  knowing  failure  to  report  (up  to  a  maximum  per  annual  report  of  $1,150,000).
Additionally,  there  are  criminal  penalties  if  an  entity  intentionally  makes  false  statements  in  such  reports.  We  are  subject  to  the  Sunshine  Act  and  the
information we disclose may lead to greater scrutiny, which may result in modifications to established practices and additional costs. Additionally, similar
reporting requirements have also been enacted on the state level domestically, and an increasing number of countries worldwide either have adopted or are
considering similar laws requiring transparency of interactions with healthcare professionals.

Foreign Corrupt Practices Act.    The Foreign Corrupt Practices Act, or FCPA, prohibits any United States individual or business from paying,
offering, or authorizing payment or offering of anything of value, directly or indirectly, to any foreign official, political party, or candidate for the purpose
of  influencing  any  act  or  decision  of  the  foreign  entity  in  order  to  assist  the  individual  or  business  in  obtaining  or  retaining  business.  The  FCPA  also
obligates companies whose securities are listed in the United States to comply with accounting provisions requiring us to maintain books and records that
accurately and fairly reflect all transactions of the corporation, including international subsidiaries, if any, and to devise and maintain an adequate system of
internal accounting controls for international operations.

International Laws.        In  Europe,  various  countries  have  adopted  anti-bribery  laws  providing  for  severe  consequences,  in  the  form  of  criminal
penalties and/or significant fines, for individuals and/or companies committing a bribery offense. Violations of these anti-bribery laws, or allegations of
such violations, could have a negative impact on our business, results of operations and reputation. For instance, in the United Kingdom, under the Bribery
Act 2010, which went into effect in July 2011, a bribery occurs when a person offers, gives, or promises to give a financial or other advantage to induce or
reward another individual to improperly perform certain functions or activities, including any function of a public nature. Bribery of foreign public officials
also falls within the scope of the Bribery Act 2010. Under the new regime, an individual found in violation of the Bribery Act of 2010, faces imprisonment
of up to 10 years. In addition, the individual can be subject to an unlimited fine, as can commercial organizations for failure to prevent bribery.

There are also international privacy laws that impose restrictions on the access, use, and disclosure of health information. All of these laws may
impact  our  business.  Our  failure  to  comply  with  these  privacy  laws  or  significant  changes  in  the  laws  restricting  our  ability  to  obtain  required  patient
information could significantly impact our business and our future business plans.

U.S. Healthcare Reform

Changes in healthcare policy could increase our costs and subject us to additional regulatory requirements that may interrupt commercialization of
our current and future solutions. Changes in healthcare policy could increase our costs, decrease our revenues, and impact sales of and reimbursement for
our current and future solutions. The Affordable Care Act substantially changes the way healthcare is financed by both governmental and private insurers,
and  significantly  impacts  our  industry  principally  by  moving  healthcare  reimbursement  towards  more  value-based  and  quality-based  payment
methodologies.  The  Act  contains  a  number  of  provisions  that  impact  our  business  and  operations,  some  of  which  in  ways  we  cannot  currently  predict,
including those governing enrollment in federal healthcare programs and reimbursement changes.

There  will  continue  to  be  proposals  by  legislators  at  both  the  federal  and  state  levels,  regulators  and  third-party  payors  to  reduce  costs  while
expanding  individual  healthcare  benefits.  Certain  of  these  changes  could  impose  additional  limitations  on  the  prices  we  will  be  able  to  charge  for  our
current  and  future  solutions  or  the  amounts  of  reimbursement  available  for  our  current  and  future  solutions  from  governmental  agencies  or  third-party
payors. Furthermore, the current presidential administration and Congress may again attempt broad sweeping changes to the current healthcare laws. We
face uncertainties that might result from modification or repeal of any of the provisions of the Affordable Care Act, including as a result of current and
future executive orders and legislative actions. The impact of those changes on us and potential effect on the medical device industry as a whole is currently
unknown. But any changes to the Affordable Care Act are likely to have an impact on our results of operations and may have a material adverse effect on
our results of operations. We cannot predict what other healthcare programs and regulations will ultimately be implemented at the federal or state level or
the effect any future legislation or regulation in the United States may have on our business.

Third-Party Reimbursement

Payment  for  patient  care  in  the  United  States  is  generally  made  by  third-party  payors,  including  private  insurers  and  government  insurance
programs, such as Medicare and Medicaid. The Medicare program, the largest single payor in the United States, is a federal governmental health insurance
program  administered  by  the  Centers  for  Medicare  and  Medicaid  Services,  or  CMS,  and  covers  certain  medical  care  expenses  for  eligible  elderly  and
disabled individuals. Because a large percentage of the population with PAD includes Medicare beneficiaries, and private insurers may follow the coverage
and payment policies of Medicare, Medicare’s coverage and payment policies are significant to our operations.

Medicare  pays  PAD  treatment  facilities,  including  hospitals  and  physician  office-based  labs,  pre-determined  amounts  for  each  procedure

performed. These payment amounts differ based on a variety of factors, including:

•

•

•

•

•

Type of procedure performed—angioplasty, stent or atherectomy;

Patient-specific complexities and comorbidities;

Type of facility—hospital, teaching hospital or office-based lab;

Inpatient or outpatient status; and

Geographic region.

We receive payment from the treatment facility for our products, and the Medicare reimbursement to the facility is intended to cover the overall
cost of treatment, including the cost of products used during the procedure as well as the overhead cost associated with the facility where the procedure is
performed. For procedures performed in hospitals, the physician who performs the procedure is reimbursed separately under the Medicare physician fee
schedule. Claims for PAD procedures are typically submitted by the treatment facility and physician to Medicare or other health insurers using established
billing codes. These codes identify the procedures performed and are relied upon to determine third-party payor reimbursement amounts.

Medicare  reimbursement  for  hospital  outpatient  PAD  procedures  that  include  atherectomy  for  2023  ranged  between  approximately  $10,000  to
greater than $17,000. These amounts include the cost of disposable devices such as Ocelot and Pantheris. While reimbursement varies based on the type of
procedure performed (e.g., angioplasty, stent or atherectomy), additional device-specific reimbursement is not available. The amount of reimbursement can
vary substantially by geographical region and by facility. Payment rates of other third-party payors may follow Medicare rates, or they may be higher or
lower, depending on their particular reimbursement methodology. Because of the wide variability, it is not possible to identify an average rate for third-
party payors other than Medicare.

Human Capital

As  of  December  31,  2023,  we  had  72  employees,  including  21  in  manufacturing  and  operations,  28  in  sales  and  marketing,  8  in  research  and
development and clinical and regulatory affairs, 5 in quality assurance and 10 in finance, general administrative and executive administration. Of these 72
employees, 4 are part time employees.

None  of  our  employees  are  represented  by  a  labor  union  or  covered  by  a  collective  bargaining  agreement.  We  have  never  experienced  any

employment-related work stoppages and we consider our employee relations to be good.

We are optimistic about the potential to expand our workforce and create a more inclusive environment for all of our employees.

Diversity, Equity and Inclusion

We understand the importance of diversity in our workforce. We will continue to focus on building a pipeline of opportunities for both the hiring
and  advancement  of  qualified  individuals,  including  for  women,  persons  with  disabilities,  and  minority  groups  that  are  underrepresented  in  science  and
engineering industries. We believe that diverse perspectives will help empower our employees, patients and industry.

Communications and Engagement

Our  success  depends  on  employees  understanding  our  strategic  vision  as  well  as  our  day-to-day  objectives.  To  that  end,  we  employ  a  mix  of
communication  and  engagement  channels,  including  all-hands  meetings,  regular  leadership  meetings,  and  quarterly  updates  on  our  progress  against  our
strategic goals. We have also created a cross-functional team focused on improving the employee experience and driving engagement.

A  central  part  of  our  communications  and  engagement  efforts  are  connecting  people  to  purpose.  To  this  end,  we  regularly  share  stories  of
physicians and patients that have been treated with our devices with our employees. Their experiences reinforce our commitment to expand our reach into
new patient populations, geographies and markets.

Risks Related to Our Business

Our  quarterly  and  annual  results  may  fluctuate  significantly,  may  not  fully  reflect  the  underlying  performance  of  our  business  and  may  result  in
decreases in the price of our common stock.

Our quarterly and annual results of operations, including our revenues, profitability and cash flow, may vary significantly in the future and period-
to-period comparisons of our operating results may not be meaningful. Accordingly, the results of any one quarter or period should not be relied upon as an
indication of future performance. Our quarterly and annual financial results may fluctuate as a result of a variety of factors, many of which are outside our
control and, as a result, may not fully reflect the underlying performance of our business. Fluctuation in quarterly and annual results may decrease the value
of our common stock. Factors that may cause fluctuations in our quarterly and annual results include, without limitation:

● our  ability  to  obtain  and  maintain  FDA  clearance  and  approval  from  foreign  regulatory  authorities  for  our  products,  and  the  timing  of  such

clearances and approvals, particularly with respect to current and future generations of Pantheris, Tigereye and Ocelot product families;

● market acceptance of our Lumivascular platform and products, including Pantheris, Ocelot, Tigereye and Lightbox;

● the availability of reimbursement for our Lumivascular platform products;

● our ability to attract new customers and increase the amount of business we generate from existing customers;

● results of our clinical trials;

● the timing and success of new product and feature introductions by us or our competitors or any other change in the competitive dynamics of our

industry, including consolidation among competitors, customers or strategic partners;

● the amount and timing of costs and expenses related to the maintenance and expansion of our business and operations;

● changes in our pricing policies or those of our competitors;

● general economic, political, industry and market conditions;

● the regulatory environment;

● the hiring, training and retention of key employees, including our sales team;

● the cost and potential outcomes of any litigation;

● our ability to obtain additional financing; and

● advances and trends in new technologies and industry standards.

In addition, we rely on estimates and forecasts of our expenses and revenues to provide guidance and inform our business strategies, and some of
our  past  estimates  and  forecasts  have  not  been  accurate.  The  evolving  nature  of  our  business  makes  forecasting  operating  results  difficult.  If  we  fail  to
accurately  forecast  our  expenses  and  revenues,  our  business,  prospects,  financial  condition  and  results  of  operations  may  suffer,  and  the  value  of  our
business may decline. If our estimates and forecasts prove incorrect, we may not be able to adjust our operations quickly enough to respond to lower-than-
expected sales which, for example, could result in higher than anticipated inventory levels, or higher-than-expected expenses which, for example, could be
the result of building excess capacity.

Based upon the factors above and others beyond our control, we have a limited ability to forecast our future revenue, costs and expenses. If we fail
to  meet  or  exceed  the  operating  results  expectations  of  analysts  and  investors  or  if  analysts  and  investors  have  estimates  and  forecasts  of  our  future
performance that are unrealistic or that we do not meet, the market price of our common stock could decline. In addition, if one or more of the analysts who
cover us adversely change their recommendation regarding our stock, the market price of our common stock could decline. In the past, companies that have
experienced volatility in the market price of their stock have been subject to securities litigation. We may be the target of this type of litigation in the future,
which could result in substantial costs and divert our management’s attention from other business concerns.

You should consider our business in light of the risks and difficulties we may encounter, as described above and elsewhere in this “Risk Factors”

section. If we fail to address the risks and difficulties that we face, our business and operating results will be adversely affected.

We have a history of net losses and we may not be able to achieve or sustain profitability.

We have incurred significant losses in each period since our inception in 2007. We incurred net losses of $18.3 million in 2023 and $17.6 million
in 2022. As of December 31, 2023, we had an accumulated deficit of approximately $420.7 million. These losses and our accumulated deficit reflect the
substantial investments we have made to develop our Lumivascular platform and acquire customers.

We  expect  our  losses  to  continue  for  the  foreseeable  future  as  we  continue  to  make  significant  future  expenditures  to  develop  and  expand  our
business. In addition, as a public company, we will continue to incur significant legal, accounting and other expenses. Accordingly, we cannot assure you
that  we  will  achieve  profitability  in  the  future  or  that,  if  we  do  become  profitable,  we  will  sustain  profitability.  Our  failure  to  achieve  and  sustain
profitability would negatively impact the market price of our common stock.

There is substantial doubt about our ability to continue as a going concern, and we will need additional financing to execute our business plan, to fund
our operations and to continue as a going concern, and, if we are unable to obtain additional financing, may be required to pursue a reorganization
proceeding under applicable bankruptcy or insolvency laws, including under Chapter 11 of the U.S. Bankruptcy Code.

Since inception, we have experienced recurring operating losses and negative cash flows and we expect to continue to generate operating losses
and  consume  significant  cash  resources  for  the  foreseeable  future.  There  is  substantial  doubt  regarding  our  ability  to  continue  as  a  going  concern.  Our
independent  registered  public  accounting  firm  has  expressed  in  its  auditors’  report  on  our  2023  financial  statements,  included  in  this  Annual  Report  on
Form 10-K, an emphasis of matter paragraph relating to our ability to continue as a “going concern,” meaning that our recurring losses from operations and
negative cash flows from operations raise substantial doubt regarding our ability to continue as a going concern. We have prepared our financial statements
on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business.
Our financial statements do not include any adjustment to reflect the possible future effects on the recoverability and classification of assets or the amounts
and classification of liabilities that may result from the outcome of this uncertainty, with the exception that all borrowings are classified as current on the
balance sheets.

Under our Term Loan Agreement (the “Loan Agreement”) with CRG Partners III L.P. and certain of its affiliated funds (collectively “CRG”), a
“Material  Adverse  Change”  or  “Material  Adverse  Effect”  (each  as  defined  in  the  Loan  Agreement)  is  an  “Event  of  Default”  thereunder,  which  gives
Majority Lenders (as defined in the Loan Agreement) the right to declare amounts outstanding under the Loan Agreement immediately due and payable.
Due to the substantial doubt about our ability to continue operating as a going concern and the Event of Default that could result due to a Material Adverse
Change under the Loan Agreement, the entire amount of borrowings at December 31, 2023 and December 31, 2022 are classified as current. In addition, we
may not be able to generate sufficient liquidity or revenue to satisfy minimum liquidity and minimum revenue covenants under the Loan Agreement. If we
fail  to  satisfy  such  requirements,  we  will  be  in  default  under  the  Loan  Agreement  and  all  outstanding  amounts  under  the  Loan  Agreement  will  become
immediately due.

Majority Lenders have not purported that an Event of Default has occurred as a result of a Material Adverse Change or breach of other financial
covenants. However, there can be no guarantee that Majority Lenders will not invoke such Event of Default in the future, or that we will not experience
other Material Adverse Changes or other Material Adverse Effects, or otherwise breach our financial or other covenants under the Loan Agreement, that
could give rise to an Event of Default under the Loan Agreement.

If we are unable to generate sufficient revenue and liquidity to service our debt, we may be required to pursue a reorganization proceeding under
applicable bankruptcy or insolvency laws, including protection (“Bankruptcy Protection”) under Chapters 7 or 11 of the U.S. Bankruptcy Code. Holders of
our common stock will likely not receive any value or payments in a restructuring or similar scenario.

23

 
 
 
 
 
 
 
 
 
 
Table of Contents

In the event we pursue Bankruptcy Protection, we will be subject to the risks and uncertainties associated with such proceedings.

In the event we file for relief under the United States Bankruptcy Code, our operations, our ability to develop and execute our business plan and
our  continuation  as  a  going  concern  will  be  subject  to  the  risks  and  uncertainties  associated  with  bankruptcy  proceedings,  including,  among  others:  our
ability  to  execute,  confirm  and  consummate  a  plan  of  reorganization;  the  high  costs  of  bankruptcy  proceedings  and  related  fees;  our  ability  to  obtain
sufficient  financing  to  allow  us  to  emerge  from  bankruptcy  and  execute  our  business  plan  post-emergence,  and  our  ability  to  comply  with  terms  and
conditions  of  that  financing;  our  ability  to  continue  our  operations  in  the  ordinary  course;  our  ability  to  maintain  our  relationships  with  our  customers,
business partners, counterparties, employees and other third parties; our ability to obtain, maintain or renew contracts that are critical to our operations on
reasonably acceptable terms and conditions; our ability to attract, motivate and retain key employees; the ability of third parties to use certain limited safe
harbor  provisions  of  the  United  States  Bankruptcy  Code  to  terminate  contracts  without  first  seeking  Bankruptcy  Court  approval;  and  the  actions  and
decisions of our stakeholders and other third parties who have interests in our bankruptcy proceedings that may be inconsistent with our operational and
strategic  plans.  Any  delays  in  our  bankruptcy  proceedings  would  increase  the  risks  of  our  being  unable  to  reorganize  our  business  and  emerge  from
bankruptcy proceedings and may increase our costs associated with the bankruptcy process or result in prolonged operational disruption for us. Also, we
would  need  the  prior  approval  of  the  bankruptcy  court  for  transactions  outside  the  ordinary  course  of  business  during  the  course  of  any  bankruptcy
proceedings,  which  may  limit  our  ability  to  respond  timely  to  certain  events  or  take  advantage  of  certain  opportunities.  Because  of  the  risks  and
uncertainties associated with any bankruptcy proceedings, we cannot accurately predict or quantify the ultimate impact of events that could occur during
any such proceedings. There can be no guarantees that if we seek Bankruptcy Protection, we will emerge from Bankruptcy Protection as a going concern or
that holders of our common stock will receive any recovery from any bankruptcy proceedings.

In  the  event  we  are  unable  to  pursue  Bankruptcy  Protection  under  Chapter  11  of  the  United  States  Bankruptcy  Code,  or,  if  pursued,  successfully
emerge from such proceedings, it may be necessary to pursue Bankruptcy Protection under Chapter 7 of the United States Bankruptcy Code for all or
a part of our businesses.

In the event we are unable to pursue Bankruptcy Protection under Chapter 11 of the United States Bankruptcy Code, or, if pursued, successfully
emerge from such proceedings, it may be necessary for us to pursue Bankruptcy Protection under Chapter 7 of the United States Bankruptcy Code for all
or a part of our businesses. In such event, a Chapter 7 trustee would be appointed or elected to liquidate our assets for distribution in accordance with the
priorities  established  by  the  United  States  Bankruptcy  Code.  We  believe  that  liquidation  under  Chapter  7  would  result  in  significantly  smaller
distributions being made to our stakeholders than those we might obtain under Chapter 11 primarily because of the likelihood that the assets would have
to be sold or otherwise disposed of in a distressed fashion over a short period of time rather than in a controlled manner and as a going concern.

We may not be able to secure additional financing on favorable terms, or at all, to meet our future capital needs and our failure to obtain additional
financing when needed could force us to delay, reduce or eliminate our product development programs and commercialization efforts or cause us to
become insolvent.

On March 5, 2024, we entered into a financing as part of a broader strategic collaboration with Zylox-Tonbridge Medical Technology Co., Ltd.
(“Zylox-Tonbridge”) in which we received an aggregate of $7.5 million before any commissions, legal and accounting fees, and other ancillary expenses.
We believe that our cash and cash equivalents at December 31, 2023, together with the aforementioned financing, debt and other financing activities and
expected  revenues  from  operations,  will  be  sufficient  to  satisfy  our  capital  requirements  and  fund  our  operations  through  the  second  quarter  of  2024.
Even though we received net proceeds of approximately $6.7 million from the sale of our Series D Convertible Preferred Stock in January 2022, $4.4
million from the sale of our common stock in August 2022, and $5.1 million from the sale of our common stock under our at-the-market program that we
entered into on May 20, 2022, we will need to raise additional funds through future equity or debt financings in the near future to meet our operational
needs and capital requirements for product development, clinical trials and commercialization, and to regain compliance with the Equity Requirement
under the Nasdaq Listing Rules. We can provide no assurance that we will be successful in raising funds pursuant to additional equity or debt financings
or that such funds will be raised at prices that do not create substantial dilution for our existing stockholders. Given the volatility of our stock price, any
financing  that  we  undertake  could  cause  substantial  dilution  to  our  existing  stockholders.  Macroeconomic  challenges  and  volatility  in  capital  markets
could further limit our ability to raise capital when needed on terms favorable to us, or at all. In addition, while we have been able to raise capital from
the sale of shares under our at-the-market program, the limitations under instruction I.B.6 of Form S-3, as well as possible low volume of trading in our
securities, will limit our ability to continue raising funds through such program.

24

 
 
 
 
 
 
 
Table of Contents

To date, we have financed our operations primarily through sales of our products and net proceeds from the issuance of our preferred stock and
debt financings, our initial public offering (“IPO”), private offerings, strategic investment, and our follow-on public offerings of our securities. We do not
know when or if our operations will generate sufficient cash to fund our ongoing operations. We cannot be certain that additional capital will be available as
needed on acceptable terms, or at all. In the future, we may require additional capital in order to (i) continue to conduct research and development activities,
(ii)  conduct  post-market  clinical  studies,  as  well  as  clinical  trials  to  obtain  regulatory  clearances  and  approvals  necessary  to  commercialize  our
Lumivascular platform products, (iii) expand our sales and marketing infrastructure, (iv) acquire complementary businesses technologies or products; or (v)
respond  to  business  opportunities,  challenges,  a  decline  in  sales,  increased  regulatory  obligations  or  unforeseen  circumstances.  Our  future  capital
requirements will depend on many factors, including:

● the  degree  of  success  we  experience  in  commercializing  our  Lumivascular  platform  products,  particularly  Pantheris,  Ocelot,  Tigereye  and  any

future versions of such products;

● the costs, timing and outcomes of clinical trials and regulatory reviews associated with our future products;

● the costs and expenses of maintaining or expanding our sales and marketing infrastructure and our manufacturing operations;

● the  costs  and  timing  of  developing  variations  of  our  Lumivascular  platform  products  and,  if  necessary,  obtaining  FDA  clearance  of  such

variations;

● the  costs  and  timing  of  developing  our  Coronary  products,  timing  and  outcomes  of  clinical  trials  and  regulatory  reviews  associated  with  this

product and eventual timing and expenses related to obtaining FDA clearance;

● the extent to which our Lumivascular platform is adopted by hospitals for use by interventional cardiologists, vascular surgeons and interventional

radiologists in the treatment of PAD;

● the number and types of future products we develop and commercialize;

● the costs of defending ourselves against future litigation;

● the costs of preparing, filing and prosecuting patent applications and maintaining, enforcing and defending intellectual property-related claims;

and

● the extent and scope of our general and administrative expenses.

We may attempt to raise additional funds in equity or debt financings or enter into credit facilities in order to access funds for our capital needs.
Any debt financing obtained by us in the future would cause us to incur additional debt service expenses and could include restrictive covenants relating to
our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and pursue
business opportunities. In addition, due to our current level of debt, future equity investors may require that we convert all or a portion of our debt to equity,
and our debtholders may not agree to such terms. If we raise additional funds through further issuances of equity or convertible debt securities, and/or if we
convert  all  or  a  portion  of  our  existing  debt  to  equity,  our  existing  stockholders  could  suffer  significant  dilution  in  their  percentage  ownership  of  our
company, and any new equity securities we issue could have rights, preferences and privileges senior to those of holders of our common stock.

If  we  are  unable  to  obtain  adequate  financing  or  financing  on  terms  satisfactory  to  us  when  we  require  it,  we  may  terminate  or  delay  the
development of one or more of our products, delay clinical trials necessary to market our products, delay establishment of sales and marketing capabilities
or  other  activities  necessary  to  commercialize  our  products,  and  significantly  scale  back  our  operations,  or  we  may  become  insolvent.  In  addition,  as
described  above  under  the  risk  factor  “Nasdaq  may  delist  our  securities  from  its  exchange,  which  could  harm  our  business  and  limit  our
stockholders’ liquidity,”  if  we  are  unable  to  raise  capital  in  a  manner  accretive  to  our  stockholders’  equity,  our  common  stock  could  be  delisted  from
Nasdaq. If this were to occur, our ability to continue to grow and support our business and to respond to business challenges could be significantly limited.

We have entered into a license agreement and related collaboration agreement with respect to the development and commercialization of certain of our
products in the Greater China region. There can be no guarantee that such strategic partnership will be successful and we may not be able to capitalize
on the market potential of our products in the Greater China region or realize other benefits from such arrangement.

In March 2024, we entered into a license agreement and collaboration agreement with Zylox-Tonbridge, pursuant to which we agreed to license
and  distribute  certain  of  our  products  to  Zylox-Tonbridge  in  the  Greater  China  region,  including  mainland  China,  Hong  Kong,  Macao,  and  Taiwan  (the
“Territory”). Zylox-Tonbridge will lead all regulatory and commercialization activities for our products in the Territory. We have limited control over the
amount and timing of resources that Zylox-Tonbridge will dedicate to such efforts and there can be no guarantee that Zylox-Tonbridge will be successful in
obtaining required regulatory approvals or commercializing such products in the Territory. As a result, we may never realize any royalty payments under
such license agreement.

In addition, as part of this strategic partnership, Zylox-Tonbridge agreed to invest $7.5 million to purchase shares of a new Series G convertible
preferred  stock,  provided  that  the  following  milestones  are  achieved:  (i)  the  successful  registration  and  listing  under  21  CFR  part  807  with  the  FDA  of
Zylox-Tonbridge and one of its designated affiliates to manufacture our products, and (ii) us achieving an aggregate of $10 million in gross revenue within
any four consecutive fiscal quarters, excluding any gross revenue achieved under the license agreement. There can be no guarantee that such milestones
will be achieved and, therefore, we may never receive such additional investment.

Furthermore, the collaboration agreement we entered into with Zylox-Tonbridge contemplates that, after required regulatory approvals have been
obtained,  Zylox-Tonbridge  will  manufacture  our  products.  There  can  be  no  guarantee  that  such  regulatory  approvals  will  be  obtained  and  that  Zylox-
Tonbridge will be able to manufacture our products. Even if Zylox-Tonbridge is able to manufacture our products, there can be no guarantee that they will
be able to do so at costs that will be advantageous to us.

We have a significant amount of debt, which may adversely affect our ability to operate our business and our financial position and our ability to secure
additional financing in the future.

As of December 31, 2023, we had $14.3 million in principal, back-end fees and interest outstanding under the Loan Agreement, with CRG. Our

significant amount of debt may:

● increase our vulnerability to adverse changes in general economic, industry and competitive conditions;

● require us to dedicate a substantial portion of our cash flow from operations to make payments on our debt, thereby reducing the availability of our

cash flow to fund working capital, capital expenditures and other general corporate purposes;

● limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate;

● restrict us from exploiting business opportunities;

● make it more difficult to satisfy our financial obligations, including payments on the Loan Agreement;

● place us at a competitive disadvantage compared to our competitors that have less debt obligations; and

● limit  our  ability  to  borrow  additional  funds  for  working  capital,  capital  expenditures,  acquisitions,  debt  service  requirements,  execution  of  our

business strategy or other general corporate purposes on satisfactory terms or at all.

The existence of a substantial amount of debt may make it difficult for us to run our business effectively or raise the capital we need to continue

our operations.

Table of Contents

Covenants under the Loan Agreement will restrict our business in many ways.

The Loan Agreement contains various covenants that limit, subject to certain exceptions, our ability to, among other things:

● incur or assume liens;

● incur additional debt or provide guarantees in respect of obligations of other persons;

● issue redeemable stock and preferred stock;

● pay dividends or make distributions on capital stock, repurchase, redeem or make payments on capital stock or repay, repurchase, redeem, retire,

defease, acquire or cancel debt prior to the stated maturity thereof;

● make loans, investments or acquisitions;

● create or permit restrictions on the ability of our subsidiaries to pay dividends or make other distributions to us or to guarantee our debt, limit our

or any of our subsidiaries ability to create liens, or make or pay intercompany loans or advances;

● enter into certain transactions with affiliates;

● sell, transfer, license, lease or dispose of our or our subsidiaries’ assets, including the capital stock of our subsidiaries; and

● dissolve, liquidate, consolidate or merge with or into, or sell substantially all of our assets to another person.

In particular, the Loan Agreement, as most recently amended in March 2024, includes a covenant that we maintain a minimum of $3.5 million of
cash and certain cash equivalents, which was temporarily reduced to a minimum of $1.0 million until April 1, 2024. Thereafter, we will be subject to the
minimum liquidity requirement of $3.5 million. There can be no assurance as to our future compliance with the covenants under the Loan Agreement, as
amended. We currently anticipate that, if we are unable to raise additional capital, our cash balance will fall below the required minimum of $3.5 million in
the  second  quarter  of  2024.  If  our  cash  balance  falls  below  the  required  minimum  and  we  are  unable  to  negotiate  a  waiver  or  amendment  to  the  Loan
Agreement, we would be in default of our covenants under the Loan Agreement, which would adversely affect on our financial position and operations.

The covenants contained in the Loan Agreement could also adversely affect our ability to execute our business strategies by restricting our ability
to make capital expenditures, engage in strategic acquisitions, refinance our outstanding indebtedness, or obtain additional financing. Such restrictions may
make it difficult to plan for or react to changes in market conditions, such as future downturns in our business or the economy in general.

In addition, potential sources of equity financing may decline to invest in our company given the amount of debt and the rights that debt holders
have to get paid before equity holders. In order to facilitate equity investments, future equity investors may require that we convert all or a portion of our
debt to equity, and our debtholders may not agree to such terms. The amount of debt could therefore affect our ability to finance our company and prevent
us from obtaining necessary operating capital as a result.

We may not be able to generate sufficient cash to service our obligations under the Loan Agreement. If we default on payments or otherwise fail to
comply with our obligations under our Loan Agreement, the lenders thereunder may be able to accelerate amounts owed under the loan facility and
may foreclose upon the assets securing our obligations.

Borrowings under our Loan Agreement are secured by substantially all of our personal property, including our intellectual property. The existing
collateral pledged under the Loan Agreement may prevent us from being able to secure additional debt or equity financing on favorable terms, or at all, or
to pursue business opportunities, including potential acquisitions. Our ability to make scheduled payments, comply with our debt covenants, or to refinance
our  debt  obligations  depends  on  numerous  factors,  including  the  amount  of  our  cash  reserves  and  our  actual  and  projected  financial  and  operating
performance.  These  amounts  and  our  performance  are  subject  to  numerous  risks,  including  the  risks  in  this  section,  some  of  which  may  be  beyond  our
control.  We  cannot  assure  you  that  we  will  maintain  a  level  of  cash  reserves  or  cash  flows  from  operating  activities  sufficient  to  permit  us  to  pay  the
principal,  premium,  if  any,  and  interest  on  our  existing  or  future  indebtedness.  If  our  cash  flows  and  capital  resources  are  insufficient  to  fund  our  debt
service obligations, we may be forced to reduce or delay capital expenditures, sell assets or operations, seek additional capital or restructure or refinance
our indebtedness. We cannot assure you that we would be able to take any of these actions, or that these actions would permit us to meet our scheduled debt
service  obligations.  In  addition,  in  the  event  of  our  breach  of  the  Loan  Agreement,  we  may  be  required  to  repay  any  outstanding  amounts  earlier  than
anticipated. If we fail to comply with our obligations under the Loan Agreement, the lender would be able to accelerate the required repayment of amounts
due and, if they are not repaid, could foreclose upon our assets securing our obligations under the Loan Agreement.

The Series E and Series F convertible preferred stock have a liquidation preference senior to our common stock, Series A-1 convertible preferred stock
and Series B convertible preferred stock.

Our outstanding shares of Series E and Series F preferred stock have a liquidation preference that gets paid prior to any payment on our common
stock (including shares issuable upon the exercise of our outstanding warrants) , Series A-1 and Series B preferred stock. The payment of the liquidation
preferences could result in common stockholders, A-1 and Series E preferred stockholders and warrant holders not receiving any consideration if we were
to liquidate, dissolve or wind up, either voluntarily or involuntarily. This liquidation preference may increase over time based on the payment of dividends.

The existence of the liquidation preferences may reduce the value of our common stock, make it harder for us to sell shares of common stock in

offerings in the future, or prevent or delay a change of control.

We have outstanding shares of convertible preferred stock, some of which contain “full-ratchet” anti-dilution protection, which may cause significant
dilution to our stockholders.

As of December 31, 2023, we had outstanding 1,279,928 shares of common stock. As of that date we had outstanding 1,920 shares of Series E
convertible preferred stock convertible into an aggregate of 178,560 share of common stock, 85 shares of Series B convertible preferred stock convertible
into an aggregate of 14,790 shares of common stock; and subsequent to December 31, 2023, we issued 10,000 shares of Series A-1 convertible preferred
stock  convertible  into  an  aggregate  of  2,729,258  shares  of  common  stock  and  7,224  shares  of  Series  F  convertible  preferred  stock  convertible  into  an
aggregate of approximately 1,971,616 shares of common stock. The issuance of shares of common stock upon the conversion of such shares of preferred
stock would dilute the percentage ownership interest of all stockholders, might dilute the book value per share of our common stock and would increase the
number of our publicly traded shares, which could depress the market price of our common stock. The shares of Series B preferred stock contain a “full-
ratchet” anti-dilution provision which, subject to limited exceptions, would reduce the conversion price of the Series B preferred stock (and increase the
number of shares issuable) in the event that we in the future issue common stock, or securities convertible into or exercisable to purchase common stock, at
price per share lower than the conversion price then in effect. Our outstanding 85 shares of Series B preferred stock were convertible into 14,790 shares of
common stock at a conversion price of $5.732 per share as of December 31, 2023.

Certain  of  our  outstanding  warrants  and  preferred  investment  options  include  put  rights  upon  the  occurrence  of  a  fundamental  transaction,  which
could make it difficult for us to complete a fundamental transaction that would otherwise be beneficial to our stockholders.

Certain  of  our  outstanding  warrants,  including  the  warrants  issued  in  February  2018,  November  2018,  and  January  2022  and  the  preferred
investment  options  issued  in  August  2022,  include  provisions  that,  in  the  event  of  certain  fundamental  transactions  defined  in  the  relevant  agreements,
provide  the  holders  of  such  warrants  and  preferred  investment  options  with  the  right  to  require  us,  or  the  successor  company  in  such  transaction,  to
repurchase any unexercised portion of such warrants or preferred investment options from the holder at their Black-Scholes value. In some circumstance
this  repurchase  must  be  made  in  cash.  Such  Black-Scholes  value  may  be  significant  and  the  requirement  to  pay  such  amount  could  prevent  us  from
completing a transaction which would otherwise be accretive to shareholders or make such transaction more costly and reduce the value of such transaction
to holders of our common stock.

Our success depends in large part on a limited number of products, particularly the Pantheris product family, all of which have a limited commercial
history. If these products fail to gain, or lose, market acceptance, our business will suffer.

Ocelot, Ocelot PIXL, Ocelot MVRX, Tigereye, Tigereye ST, Lightbox 3, Pantheris, Pantheris SV and Pantheris LV are our only products currently
cleared for sale, and our current revenues are wholly dependent on them. In addition, the long-term viability of our company is largely dependent on the
successful  commercialization  and  continued  development  of  the  Pantheris  product  family  and  we  expect  that  sales  of  our  other  current  and  future
Lumivascular platform products in the United States will account for substantially all of our revenues for the foreseeable future. Accordingly, our success
depends on the continued and growing acceptance and use of Lumivascular platform products by the medical community.

All of our products have a limited commercial history. For example, we received 510(k) clearance from the FDA to commercialize Pantheris in
October 2015 as well as a separate FDA clearance to market enhanced versions of Pantheris in March 2016 and May 2018 and those versions of Pantheris
became commercially available in the United States and select international markets promptly thereafter. Pantheris SV launched in July 2019 after having
received FDA clearance in April 2019. Tigereye launched in October 2020 after having received FDA clearance in September 2020. Tigereye ST launched
in  September  2023  after  having  received  FDA  clearance  in  April  2023.  Pantheris  LV  is  currently  in  a  limited  launch  phase  after  having  received  FDA
clearance in June 2023.Our limited commercialization experience and number of approved products make it difficult to evaluate our current business and
predict  our  future  prospects.  We  have  encountered  and  will  continue  to  encounter  risks  and  difficulties  frequently  experienced  by  companies  in  rapidly
changing industries.

Our ability to successfully market Lumivascular platform products will also be limited due to a number of factors including regulatory restrictions
in our labeling. We cannot assure demand for Lumivascular platform products will continue to grow or that our products will significantly penetrate current
or  new  markets.  Market  demand  for  our  Lumivascular  platform  products  and  physician  adoption  of  these  products  also  may  be  negatively  impacted  by
product performance issues and the need to replace certain products in accordance with our warranty policy. Utilization of our products has been less than
we anticipated historically. If demand for our Lumivascular platform products does not increase and we cannot sell our products as planned, our financial
results will be harmed. In addition, market acceptance may be hindered if physicians are not presented with compelling data from long-term studies of the
safety  and  efficacy  of  our  Lumivascular  platform  products  compared  to  alternative  procedures,  such  as  angioplasty,  stenting,  bypass  surgery  or  other
atherectomy  procedures.  For  example,  if  patients  undergoing  treatment  with  our  Lumivascular  platform  products  have  retreatment  rates  higher  than  or
comparable with the retreatment rates of alternative procedures, it will be difficult to demonstrate the value of our Lumivascular platform products. Any
studies we may conduct comparing our Lumivascular platform with alternative procedures will be expensive, time consuming and may not yield positive
results. Physicians will also need to appreciate the value of real-time imaging in improving patient outcomes in order to change current methods for treating
PAD  patients.  In  addition,  demand  for  our  Lumivascular  platform  products  may  decline  or  may  not  increase  as  quickly  as  we  expect.  Failure  of  our
Lumivascular platform products to significantly penetrate current or new markets, or our failure to successfully commercialize our products, would harm
our business, financial condition and results of operations.

29

We are also aware of certain characteristics and features of our Lumivascular platform that may prevent widespread market adoption. For example,
in procedures using the current model of Pantheris, some physicians may prefer to have a technician or second physician assisting with the operation of the
catheter  as  well  as  a  separate  technician  to  operate  the  Lightbox,  potentially  making  it  less  financially  attractive  for  physicians  and  their  hospitals  and
medical  facilities.  It  may  take  significant  time  and  expense  to  modify  our  products  to  allow  a  single  physician  to  operate  the  entire  system  and  we  can
provide no guarantee that we will be able to make such modifications or obtain any additional and necessary regulatory clearances for such modifications.
Although the OCT images created by our Lightbox may make it possible for physicians to reduce the degree to which fluoroscopy and contrast dye are used
when using our Lumivascular platform products compared to competing endovascular products, physicians are still using both fluoroscopy and contrast dye
in  these  procedures.  As  a  result,  risks  of  complications  from  radiation  and  contrast  dye  are  still  present  and  may  limit  the  commercial  success  of  our
products. Finally, it requires training of technicians and physicians to effectively operate our Lumivascular platform products, including interpreting the
OCT images created by our Lightbox, which may affect adoption of our products by physicians.

Our Lumivascular products are highly complex, and the failure of relatively minor components could result in product failure or other significant
performance issues that may not be discovered until after delivery to customers, which could give rise to claims from our customers or their patients. We
have in the past, and may in the future, become aware of performance issues with our products. For example, prior to becoming commercially available on
March 1, 2016, Pantheris had been used in clinical trials mainly in controlled situations. Since its commercialization and as more physicians have used
Pantheris, we have received additional feedback on its performance, both positive and negative. We have attempted to address certain of these concerns
with our current version of Pantheris. However, there can be no assurance that the changes and improvements will fully address the performance issues that
have  been  raised  by  earlier  versions  of  Pantheris.  Our  revenue  has  been  adversely  impacted  by  these  product  performance  issues.  We  also  had  to  incur
additional  expenses  to  make  product  changes  and  improvements,  and  to  replace  products  in  accordance  with  our  warranty  policy.  If  future  product
performance issues are not resolved and physician concerns not addressed, our reputation could suffer, which could lead to decreased sales of our products.

We rely heavily on our sales professionals to market and sell our products. If we are unable to hire, effectively train, manage, improve the productivity
of, and retain our sales professionals, our business will be harmed, which would impair our future revenue and profitability.

Our success largely depends on our ability to hire, train, manage and improve the productivity levels of our sales professionals. Competition for
sales professionals who are familiar with and trained to sell our products continues to be strong and our larger competitors are able to offer compensation
and benefits that we are not able to. We have experienced and continue to experience significant turnover of our sales professionals. Significant turnover of
our sales professionals makes it difficult for us to maintain an adequate presence in some markets and to preserve institutional expertise among our sales
teams. While we train our new sales professionals to better understand our existing and new product technologies and how they can be positioned against
our competitors’ products, it takes time for the sales professionals to become productive following their hiring and training and there can be no assurance
that newly hired sales professionals will reach adequate levels of productivity, or that we will not continue to experience significant levels of attrition in the
future. Measures we implement to improve the productivity of our sales professionals may not be successful and may instead cause additional departures
from  our  sales  organization.  Such  attrition  could  further  reduce  our  revenue,  profitability,  and  harm  our  business  and  our  stock  price  may  be  adversely
impacted as a result. 

In addition, the loss of any member of our sales team’s senior management could weaken our sales expertise and harm our business, and we may
not be able to find adequate replacements on a timely basis, or at all. Attrition in our senior management team over sales that have occurred over the past
several  years  have  created  and  likely  will  continue  to  create  instability  in  our  sales  force,  which  could  lead  to  further  attrition  in  our  team  of  sales
professionals. If we are unable to retain experienced sales professionals, our ability to market and sell our products in our target markets will be adversely
affected, which will adversely affect our sales and results of operations.

We depend on our senior management team and the loss of one or more key employees or an inability to attract and retain highly skilled employees
could harm our business.

Our success largely depends upon the continued services of our executive management team and key employees and the loss of one or more of our
executive officers or key employees could harm us and directly impact our financial results. Our employees may terminate their employment with us at any
time. Changes in our executive management team resulting from the hiring or departure of executives could disrupt our business. For example, our Chief
Financial Officer resigned from the Company effective May 12, 2022. Nabeel Subainati, our Vice President of Finance, has been designated as Principal
Financial Officer and Principal Accounting Officer effective as of July 21, 2022. If we are unable to hire one or more replacement employees for officers
who have departed or may depart, or otherwise fill their responsibilities, our ability to effectively manage our business could be adversely affected.

We must attract and retain highly qualified personnel. Competition for skilled personnel is intense, especially for engineers with high levels of
experience in designing and developing medical devices and for sales professionals. We have, from time to time, experienced, and we expect to continue to
experience, difficulty in hiring and retaining employees with appropriate qualifications. Many of the companies with which we compete for experienced
personnel have greater resources than we have. If we hire employees from competitors or other companies, their former employers may attempt to assert
that these employees or we have breached legal obligations, resulting in a diversion of our time and resources and, potentially, damages. In addition, job
candidates and existing employees, particularly in the San Francisco Bay Area, often consider the value of the stock awards they receive in connection with
their employment. If the perceived value of our stock awards declines or if we do not make grants of stock-based incentive awards, it may harm our ability
to recruit and retain highly skilled employees. In addition, we invest significant time and expense in training our employees, which increases their value to
competitors who may seek to recruit them. If we fail to attract new personnel or fail to retain and motivate our current personnel, our business would be
harmed.

Our ability to compete is highly dependent on demonstrating the benefits of our Lumivascular platform to physicians, hospitals and patients and our
ability to innovate new and improved products.

In order to generate sales, we must be able to clearly demonstrate that our Lumivascular platform is a more effective treatment system than the
alternatives  offered  by  our  competitors.  If  we  are  unable  to  convince  physicians  that  our  Lumivascular  platform  leads  to  significantly  lower  rates  of
restenosis, or narrowing of the artery, and leads to fewer adverse events during treatment than those using competing technologies, our business will suffer.
We must convince hospitals and physicians that our Lumivascular platform results in significantly better patient outcomes at a competitive overall cost. For
example, we may need to demonstrate that the investment hospitals must make of purchasing our Lightbox and the incremental costs of having a technician
or  a  second  individual  operate  Pantheris  can  be  justified  based  on  the  benefits  to  patients,  physicians  and  hospitals.  If  we  are  unable  to  develop  robust
clinical  data  to  support  these  claims,  we  will  be  unable  to  convince  hospitals  and  third-party  payors  of  these  benefits  and  our  business  will  suffer.  In
addition, attrition among our sales professionals may make it difficult to maintain relationships with physicians and hospitals, which could adversely affect
our sales and results of operations.

Our value proposition to physicians and hospitals is largely dependent upon our contention that the rate of arterial damage when physicians are
using  our  imaging  products  is  lower  than  with  non-imaging  competing  products.  If  minimizing  arterial  damage  does  not  significantly  impact  patient
outcomes, meaning either (i) that restenosis is often triggered without disrupting healthy arterial structures or (ii) arteries can be damaged during treatment
without triggering restenosis, then we may be unable to demonstrate our Lumivascular platform’s benefits are any different than competing technologies.
Furthermore, physicians may find our imaging system difficult to use, and we may not be able to provide physicians with adequate training to be able to
realize the benefits of our Lumivascular platform. If physicians do not value the benefits of on-board imaging and the enhanced visualization enabled by
our products during an endovascular intervention as compared to our competitors’ products, or do not believe that such benefits improve clinical outcomes,
our Lumivascular platform products may not be widely adopted.

In order to remain competitive, we must also continue to develop new product offerings and enhancements to our existing Lumivascular platform
products.  The  market  for  medical  devices  in  general,  and  in  the  PAD  market  in  particular,  is  highly  competitive,  dynamic,  and  marked  by  rapid  and
substantial technological development and product innovation. If we are unable to innovate successfully, our Lumivascular platform products could become
obsolete, and our revenues would decline as our customers purchase our competitors’ products. In addition, our innovation efforts may not result in new
products that generate additional revenue. For example, we believe that our next-generation Pantheris, Pantheris SV, Pantheris LV and any future iterations
of these products are important to our future revenues, and we are devoting a significant portion of our resources to their continued development. However,
we do not yet know whether these or any other new offerings will be well received and broadly accepted by physicians, and if so, whether sales will be
sufficient  for  us  to  offset  costs  of  development,  implementation,  support,  operation,  sales  and  marketing.  Additionally,  new  products  may  subject  us  to
additional  risks  of  product  performance,  market  adoption,  customer  complaints  and  litigation.  If  sales  of  our  new  product  offerings  are  lower  than  we
expect, fail to gain anticipated market acceptance or cause us to expend additional resources to fix unforeseen problems and develop modifications, our
revenues and results of operations may not improve, and our business will be adversely affected.

Our ability to develop, market, and sell our products depends in part upon our working relationships with physicians, and any events that damage those
relationships, or make it more difficult to build and maintain those relationships, could harm our business.

The development, marketing, and sale of our products depends upon our ability to maintain strong working relationships with physicians. We rely
on  these  professionals  to  provide  us  with  considerable  knowledge  and  experience  regarding  the  development,  marketing  and  sale  of  our  products.
Physicians assist us in clinical trials and as researchers, marketing and product consultants and public speakers. If we cannot maintain our strong working
relationships with these professionals and continue to receive their advice and input, the development and marketing of our products could suffer, which
could  harm  our  business,  financial  condition  and  results  of  operations.  The  medical  device  industry’s  relationship  with  physicians  is  under  increasing
scrutiny by the Office of Inspector General, or OIG, the Department of Justice, or DOJ, state attorneys general, and other foreign and domestic government
agencies.  Changes  to  or  our  failure  to  comply  with  laws,  rules  and  regulations  governing  our  relationships  with  physicians,  or  an  investigation  into  our
compliance by the OIG, DOJ, state attorneys general and other government agencies, could significantly harm our business by damaging our reputation
among, or restricting our ability to work with, physicians.

In addition, we target our sales efforts to interventional cardiologists, vascular surgeons and interventional radiologists because they are often the
physicians diagnosing and treating both coronary artery disease and PAD. If these physicians are not made aware of our Lumivascular platform products,
those patients may instead be surgically treated or treated with an alternative interventional procedure. In addition, there is a significant correlation between
PAD and coronary artery disease, and many physicians do not routinely screen for PAD while screening for coronary artery disease. If we are not successful
in educating physicians about screening for PAD and about the capabilities of our Lumivascular platform products, our ability to increase our revenues may
be impaired.

We  compete  against  companies  that  have  longer  operating  histories,  more  established  products  and  greater  resources,  which  may  prevent  us  from
achieving significant market penetration, increasing our revenues or becoming profitable.

Our products compete with a variety of products and devices for the treatment of PAD, including other CTO crossing devices, stents, balloons and
atherectomy  catheters,  as  well  as  products  used  in  vascular  surgery.  Large  competitors  in  the  CTO  crossing,  stent  and  balloon  markets  include  Abbott
Laboratories, AngioDyamics, Boston Scientific, Cardinal Health, Cook Medical, Becton Dickinson and Medtronic. Competitors in the atherectomy market
include  AngioDyamics,  Boston  Scientific,  Cardiovascular  Systems,  Medtronic  and  Philips.  Some  competitors  have  previously  attempted  to  combine
intravascular imaging with atherectomy and may have current programs underway to do so. These and other companies may attempt to incorporate on-
board visualization into their products in the future and may remain competitive with us in marketing traditional technologies. Other competitors include
pharmaceutical  companies  that  manufacture  drugs  for  the  treatment  of  symptoms  associated  with  mild  to  moderate  PAD  and  companies  that  provide
products used by surgeons in peripheral and coronary bypass procedures. These competitors and other companies may introduce new products that compete
with our products. Many of our competitors have significantly greater financial and other resources than we do and have well-established reputations, as
well as broader product offerings and worldwide distribution channels that are significantly larger and more effective than ours. In addition, competitors
with greater financial resources than ours could acquire other companies to gain enhanced name recognition and market share, as well as new technologies
or products that could effectively compete with our existing products, which may cause our revenues to decline and would harm our business. Competition
with  these  companies  could  result  in  price-cutting,  reduced  profit  margins  and  loss  of  market  share,  any  of  which  would  harm  our  business,  financial
condition and results of operations.

If we are unable to effectively differentiate our products or company from those of our competitors and our business may be adversely affected.

If our manufacturing facility becomes damaged or inoperable, or we are required to vacate the facility, or our electronic systems are compromised, our
ability to manufacture and sell our Lumivascular platform products and to pursue our research and development efforts may be jeopardized.

We currently manufacture and assemble our Lumivascular platform products in-house. Our products are comprised of components sourced from a
variety of contract manufacturers, with final assembly completed at our facility in Redwood City, California. Our facility and equipment, or those of our
suppliers,  could  be  harmed  or  rendered  inoperable  by  natural  or  man-made  disasters,  including  fire,  earthquake,  terrorism,  flooding  and  power  outages.
Further, our electronic systems may experience service interruptions, denial-of-service and other cyber-attacks, computer viruses or other events. Any of
these may render it difficult or impossible for us to manufacture products, pursue our research and development efforts or otherwise run our business for
some period of time. If our facility is inoperable for even a short period of time, the inability to manufacture our current products, and the interruption in
research  and  development  of  any  future  products,  may  result  in  harm  to  our  reputation,  increased  costs,  lower  revenues  and  the  loss  of  customers.
Furthermore, it could be costly and time-consuming to repair or replace our facilities and the equipment we use to perform our research and development
work and manufacture our products.

We depend on third-party vendors to manufacture some of our components, coating and sub-assemblies, including some single source suppliers, which
could make us vulnerable to supply shortages and price fluctuations that could harm our business.

We  currently  manufacture  some  of  our  components  and  sub-assemblies  at  our  Redwood  City  facility  and  rely  on  third-party  vendors  for  other
components and sub-assemblies used in our Lumivascular platform. For several of our components and sub-assemblies we rely on single and limited source
suppliers. For example, we rely on single vendors for our optical fiber, coatings and drive cables that are key components of our catheters, and we rely on
single vendors for our laser and data acquisition card that are key components of our Lightbox. These components are critical to our products and there are
relatively few alternative sources of supply. Further, we do not carry a significant inventory of these components. If our suppliers of these materials cease
doing  business,  reduce  their  production  capacity,  or  otherwise  limit  the  amount  of  materials  we  can  purchase,  we  may  be  unable  to  acquire  necessary
materials on favorable terms, or at all. If we are unable to purchase required inputs for our production, our business will be adversely affected.

Our reliance on third-party vendors subjects us to a number of risks that could impact our ability to manufacture our products and harm our business.

We rely on third-party vendors to supply us with raw materials, as well as certain components and sub-assemblies used in the manufacture of our

products. Our reliance on such third parties subjects us to a number of risks that could adversely affect our operations, including:

interruption of supply resulting from modifications to, or discontinuation of, a supplier’s operations;
delays  in  shipments  resulting  from  slowdowns  in  manufacturing  due  to  a  pandemic  or  other  causes,  such  as  government  restrictions  on  the
movement of people and goods;
delays  in  product  shipments  resulting  from  uncorrected  defects,  reliability  issues  or  a  supplier’s  failure  to  consistently  produce  quality
components;
price fluctuations due to a lack of long-term supply arrangements with our suppliers for key components;
inability to obtain adequate supply in a timely manner or on commercially reasonable terms;
difficulty identifying and qualifying alternative or additional suppliers for components in a timely manner;
inability of the manufacturer or supplier to comply with QSR as enforced by the FDA and state regulatory authorities;
inability to control the quality of products manufactured by third parties;
production delays related to the evaluation and testing of products from alternative suppliers and corresponding regulatory qualifications; and
delays in delivery by our suppliers due to changes in demand from us or their other customers.

The indirect and direct effects of the COVID-19 pandemic, including subsequent variants, and measures taken in response by governments and
businesses worldwide to contain its spread, including quarantines, facility closures, travel and logistics restrictions, border controls, and shelter in place or
stay  at  home  and  social  distancing  orders,  have  historically  adversely  impacted  and  are  in  some  ways  expected  to  continue  to  adversely  impact  global
supply chain, manufacturing, and logistics operations. Shipping and freight delays have also been increasing in response to port closures, port congestion,
shipping container and ship shortages, and global conflicts. To the extent events such as another pandemic or other disruptive event results the worsening of
manufacturing and shipping delays and constraints, our suppliers of raw materials and other components may have difficulty obtaining and providing the
materials we require to manufacture our products, which could adversely affect our ability to acquire and maintain adequate inventory and meet demand for
our products.

Some of our suppliers have begun requiring us to provide longer-term forecasts of our supply requirements. If our assumptions about customer
demand are incorrect, the forecasts we provide to our suppliers may result in excess inventory due to reduced demand or insufficient inventory to meet
demand, which would adversely affect our business and results of operations. We also compete with other manufacturers who require the same components
as us, or inputs used in producing the components that we purchase. Other purchasers may be able to leverage stronger relationships or greater purchasing
power than we have to gain advantages over us in the supply chain.

We do not currently intend to devote significant additional resources in the near-term to market our Lumivascular platform internationally, which will
limit our potential revenues from our Lumivascular platform products.

Marketing  our  Lumivascular  platform  outside  of  the  United  States  would  require  substantial  additional  sales  and  marketing,  regulatory  and
personnel  expenses.  As  part  of  our  product  development  and  regulatory  strategy,  we  plan  to  expand  into  select  international  markets,  but  we  do  not
currently intend to devote significant additional resources to market our Lumivascular platform internationally in order to focus our resources and efforts on
the  U.S.  market.  Our  decision  to  market  our  products  primarily  in  the  United  States  in  the  near-term  will  limit  our  ability  to  reach  all  of  our  potential
markets and will limit our potential sources of revenue. In addition, our competitors will have an opportunity to further penetrate and achieve market share
outside of the United States until such time, if ever, that we devote significant additional resources to market our Lumivascular platform products or other
products internationally.

Our ability to utilize our net operating loss carryforwards may be limited.

As of December 31, 2023, we had federal and state net operating loss carryforwards, or NOLs, due to prior period losses of $357.7 million and
$218.7 million, respectively, which if not utilized will begin to expire in 2027 for federal purposes and 2024 for state purposes. Out of the total Federal net
operating loss carryforwards, $100.2 million were generated in years after December 31, 2017 and have no expiration. Subject to certain limitations, NOLs
can be used to offset taxable income for U.S. federal income tax purposes. However, Section 382 of the Internal Revenue Code of 1986, as amended, may
limit the NOLs we may use in any year for U.S. federal income tax purposes in the event of certain changes in ownership of our company. A Section 382
“ownership change” generally occurs if one or more stockholders or groups of stockholders who own at least 5% of our stock increase their ownership by
more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. Similar rules may apply under state tax laws. It is
possible that prior transactions with respect to our stock may have caused, and that future issuances or sales of our stock (including certain transactions
involving our stock that are outside of our control) could cause, an “ownership change.” A number of our common and preferred stock financings over the
past year may affect our ability to use NOLs. If an “ownership change” occurs, Section 382 would impose an annual limit on the amount of pre-ownership
change NOLs and other tax attributes we can use to reduce our taxable income, potentially increasing and accelerating our liability for income taxes, and
also  potentially  causing  those  tax  attributes  to  expire  unused.  Any  limitation  on  using  NOLs  could  (depending  on  the  extent  of  such  limitation  and  the
NOLs previously used) result in our retaining less cash after payment of U.S. federal income taxes during any year in which we have taxable income (rather
than  losses)  than  we  would  be  entitled  to  retain  if  such  NOLs  were  available  as  an  offset  against  such  income  for  U.S.  federal  income  tax  reporting
purposes, which could harm our profitability.

On December 22, 2017, the Tax Cuts and Jobs Act, or Tax Act, was enacted into law with many significant changes to the U.S. tax laws. The Tax
Act limits the utilization of NOLs arising in tax years beginning after December 31, 2017 to 80% of taxable income per year. However, existing NOLs that
arose in years prior to December 31, 2017 are not affected by these provisions. Our ability to utilize NOLs arising in future tax periods may be limited by
the Tax Act.

Outbreaks of contagious diseases, such as the novel coronavirus, COVID-19, and other public health crises may impact our business and operations,
which could materially adversely affect our financial condition and results of operations.

We have historically experienced a disruption in procedures using our products and in our operations as a result of the COVID-19 outbreak. Public
health crises, including an outbreak of a contagious disease, such as COVID-19, particularly to the extent it becomes a pandemic like COVID-19, could
significantly disrupt our business. The effects of such a public health crisis are difficult to predict, but may include a decrease in procedure volumes due to
restrictions and guidelines implemented by facilities and governmental entities; reduced availability of physicians or lab space to treat patients using our
products  and/or  different  treatment  prioritizations  of  those  physicians;  increased  cost  pressures  and  burdens  on  the  overall  healthcare  infrastructure  that
result in reallocation of resources; changed treatment decisions by patients who may elect to defer or avoid treatment for procedures that use our products
due to concerns about the potential spread of diseases in facilities; the suspension of clinical trial activity; restrictions on the ability of our personnel and
personnel of our distribution partners and sales agents to travel and to access customers and medical facilities for sales activities, training and case support;
delays in approvals by regulatory bodies; delays in product development efforts, which will also disrupt or delay our ability to launch affected products;
reallocation of company resources from our strategic priorities; supply chain disruptions that limit, delay or prevent us from acquiring the components used
to manufacture our products or ship those products once manufactured; disruptions in our relationships with our distributors and sales agents due to the
impact  of  the  outbreak  on  their  operations;  temporary  closures  of  our  facilities;  loss  of  employee  productivity;  government  requirements  to  “shelter  at
home” or other incremental mitigation efforts that may further impact our capacity to manufacture, sell and support the use of our products; legal actions
threatened  or  commenced  against  us  by  employees,  customers  or  others  who  allege  that  our  actions  or  inactions  relating  to  safety  measures  led  to  their
exposure to COVID-19 or other personal injury; and adverse impacts on the national and global economies.

The extent of pandemics such as COVID-19, may be further aggravated by the spread of new, more viral or deadly variants. Public health crises
and  pandemics,  such  as  the  outbreak  of  COVID-19,  also  affect  the  economy  generally,  which  may  affect  our  stock  price,  our  ability  to  borrow  or  raise
additional capital, and the funding of health systems that purchase our products, among other potential effects. The United States and world economies
could enter into periods of sustained recession or depression, which could materially adversely affect our business. The total impact of these disruptions
could have a material adverse impact on our financial condition and results of operations, we cannot predict the specific extent, or duration, of the impact of
such an outbreak of a contagious disease or other public health crisis on our financial condition and results. Furthermore, the extent of a global impact from
a pandemic cannot fully be known or quantified. The full extent to which a public health crisis will directly or indirectly impact our business and results
will  depend  on  future  developments  that  are  highly  uncertain  and  difficult  to  predict.  Finally,  to  the  extent  a  public  health  crisis  adversely  affects  our
business, results and prospects, it may also have the effect of heightening many of the other risks described in this section.

Disruptions of supply chains could have a material adverse effect on our operating and financial results

Disruption of supply chains due to trade restrictions, political instability, severe weather, natural disasters, public health crises such as the COVID-
19  pandemic,  terrorism,  product  recalls,  port  closures,  labor  supply  or  stoppages,  the  financial  or  operational  instability  of  key  suppliers  and  carriers,
government restrictions or measures, or other reasons could impair our ability to distribute our products, or cause the demand for our products to decrease.
Many  industries,  including  our  own,  faced  and  continue  to  face  supply  chain  challenges  resulting  from  COVID-19  and  other  macroeconomic  issues,
including  reduced  freight  availability  and  increased  costs,  port  disruption,  manufacturing  facility  closures,  labor  shortages  and  other  supply  chain
disruptions.  For  example,  hospitals  reported  a  shortage  of  an  iodinated  contract  medium  used  in  X-rays,  radiography  and  CT  scans  due  to  Shanghai’s
lockdowns during the COVID-19 pandemic. A shortage of such products could lead to a reduced number of surgeries and decrease the demand for our
products.

In addition, we have and continue to experience supply chain challenges related to extended lead times from certain key suppliers. Should these
challenges  persist  or  worsen,  we  may  be  unable  to  manufacture  enough  inventory  to  meet  the  current  demand  for  our  Lumivascular  products  and
consequently  incur  significant  adverse  effects  on  our  operating  and  financial  results.  To  the  extent  we  are  unable  to  mitigate  the  likelihood  or  potential
impact of such events, there could be a material adverse effect on our operating and financial results.

We may acquire other companies or technologies or be the target of strategic transactions, which could divert our management’s attention, result in
additional dilution to our stockholders and otherwise disrupt our operations and harm our operating results.

We  may  in  the  future  seek  to  acquire  or  invest  in  businesses,  applications  or  technologies  that  we  believe  could  complement  or  expand  our
Lumivascular  platform,  enhance  our  technical  capabilities  or  otherwise  offer  growth  opportunities.  The  pursuit  of  potential  acquisitions  may  divert  the
attention of management and cause us to incur various costs and expenses in identifying, investigating and pursuing suitable acquisitions, whether or not
they are consummated. We may not be able to identify desirable acquisition targets or be successful in entering into an agreement with any particular target
or obtain the expected benefits of any acquisition or investment.

To  date,  our  technology  and  product  development  efforts  have  been  organic,  and  we  have  no  experience  in  acquiring  other  businesses.  In  any
acquisition,  we  may  not  be  able  to  successfully  integrate  acquired  personnel,  operations  and  technologies,  or  effectively  manage  the  combined  business
following the acquisition. Acquisitions could also result in dilutive issuances of equity securities, the use of our available cash, or the incurrence of debt,
which  could  harm  our  operating  results.  In  addition,  if  an  acquired  business  fails  to  meet  our  expectations,  our  operating  results,  business  and  financial
condition may suffer.

In addition, we sometimes receive inquiries relating to potential strategic transactions, including from third parties who may seek to acquire us. We
will continue to consider and discuss such transactions as we deem appropriate. Such potential transactions may divert the attention of management, and
cause us to incur various costs and expenses in investigating and evaluating such transactions, whether or not they are consummated.

New product development for the coronary artery disease market may be challenging, expensive and carries no guarantee of an approved commercial
product.

In  order  to  create  more  opportunities  to  grow  our  revenue  base,  we  must  continue  to  develop  new  product  offerings  and  enhancements  to  our
existing Lumivascular platform products. The market for medical devices in general, and in the CAD market, is highly competitive, dynamic, and marked
by  rapid  and  substantial  technological  development  and  product  innovation.  We  believe  that  a  Lumivascular  product  developed  for  the  CAD  market  is
important to our future revenues, and we are beginning to devote a significant portion of our resources to its development. Consequently, we anticipate we
will need additional capital to finance this endeavor encompassing the research and development, clinical trials and eventual promotion of any new CAD
product. Even if we are able to obtain additional capital, we may not be successful in the development any new CAD product.

35

 
 
 
 
 
 
 
 
 
 
 
Table of Contents

Our team may not have all the necessary qualifications and experience for the development of such a product. Therefore, we may need to attract
and retain highly qualified personnel with specific experience in the coronary industry. Competition for skilled personnel is intense, especially for engineers
with high levels of experience in designing and developing these types of medical devices, and we may not be successful in hiring and retaining employees
with appropriate qualifications. Many of the companies with which we compete for experienced personnel have greater resources than we have. We may
also  may  not  be  able  to  complete  development  of  such  products  or  choose  to  allocate  our  financial  and  other  resources  elsewhere  due  to  unforeseen
circumstances.

Should we develop a CAD product, we will need to conduct a clinical trial. Clinical development is a long, expensive, and uncertain process and is
subject  to  delays  and  the  risk  that  this  product  may  ultimately  prove  unsafe  or  ineffective  in  treating  the  indications  for  which  they  it  will  be  designed.
Completion of clinical trials may take several years or more and failure of the trial can occur at any time. We cannot provide any assurance that our clinical
trials will meet their primary endpoints or that such trials or their results will be accepted by the FDA or foreign regulatory authorities. Even if we achieve
positive early or preliminary results in clinical trials, these results do not necessarily predict final results, and positive results in early trials may not indicate
success in later trials. Many companies in the medical device industry have suffered significant setbacks in late-stage clinical trials, even after receiving
promising results in earlier trials or in the preliminary results from these late-stage clinical trials.

Furthermore,  we  do  not  yet  know  whether  any  new  CAD  product,  if  developed  and  approved,  will  be  well  received  and  broadly  accepted  by
physicians,  and  if  so,  whether  sales  will  be  sufficient  for  us  to  offset  costs  of  development,  implementation,  support,  operation,  sales  and  marketing.
Additionally, such products may subject us to additional risks of product performance, market adoption, customer complaints and litigation. If sales of this
coronary device are lower than we expect, fail to gain anticipated market acceptance or cause us to expend additional resources to fix unforeseen problems
and develop modifications, our revenues and results of operations may not improve and our business will be adversely affected.

Adverse  developments  affecting  the  financial  services  industry,  including  events  or  concerns  involving  liquidity,  defaults  or  non-performance  by
financial institutions, could adversely affect our business, financial condition or results of operations.

Actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions or the financial
services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future adversely
affect our liquidity. For example, on March 10, 2023, the Federal Deposit Insurance Corporation (“FDIC”) announced that Silicon Valley Bank had been
closed by the California Department of Financial Protection and Innovation. At that time, all of our cash and cash equivalents were held at Silicon Valley
Bank and our access to such funds was limited until the United States Department of the Treasury announced in a joint statement with the Federal Reserve
and FDIC that depositors of Silicon Valley Bank will have access to all of their money starting March 13, 2023. While we have regained access to our funds
at Silicon Valley Bank, later acquired by First Citizens Bank, and are evaluating our banking relationships, our access to funding sources and other credit
arrangements in amounts adequate to finance or capitalize our current and projected future business operations could be significantly impaired by events
such as liquidity constraints or failures, disruptions or instability in the financial services industry or financial markets, or concerns or negative expectations
about  the  prospects  for  companies  in  the  financial  services  industry.  These  factors  may  also  adversely  affect  our  ability  to  access  our  cash  and  cash
equivalents at affected financial institutions.

In  addition,  investor  concerns  regarding  the  U.S.  or  international  financial  systems  could  result  in  less  favorable  commercial  financing  terms,
including  higher  interest  rates  or  costs  and  tighter  financial  and  operating  covenants,  or  systemic  limitations  on  access  to  credit  and  liquidity  sources,
thereby making it more difficult for us to acquire financing on terms favorable to us, or at all. Any decline in available funding or access to our cash and
liquidity  resources  could,  among  other  things,  adversely  impact  our  ability  to  meet  our  operating  expenses,  financial  obligations  or  fulfill  our  other
obligations, result in breaches of our contractual obligations or result in violations of federal or state wage and hour laws. Any of these impacts, or any
other impacts resulting from the factors described above or other related or similar factors not described above, could have material adverse impacts on our
liquidity and our business, financial condition or results of operations.

Risks Related to Our Use of Technology and Intellectual Property

If our technology infrastructure is compromised, damaged or interrupted by a cybersecurity incident, data security breach or other security problems,
our operating results and financial condition could be adversely affected.

We  use  technology  in  substantially  all  aspects  of  our  business  operations,  and  our  ability  to  serve  customers  most  effectively  depends  on  the
reliability of our technology systems. Cybersecurity incidents can include computer viruses, computer denial-of-service attacks, worms, and other malicious
software programs or other attacks, covert introduction of malware to computers and networks, impersonation of authorized users, and efforts to discover
and  exploit  any  design  flaws,  bugs,  security  vulnerabilities  or  security  weaknesses,  as  well  as  intentional  or  unintentional  acts  by  employees  or  other
insiders with access privileges, intentional acts of vandalism by third parties and sabotage.

36

 
 
 
 
 
 
 
 
 
 
Table of Contents

In  addition,  our  technology  infrastructure  and  systems  are  vulnerable  to  damage  or  interruption  from  natural  disasters,  power  loss  and
telecommunications failures. Any such disruption to our systems, or the technology systems of third parties on which we rely, the failure of these systems to
otherwise  perform  as  anticipated,  or  the  theft,  destruction,  loss,  misappropriation,  or  release  of  sensitive  and/or  confidential  information  or  intellectual
property, could require us to notify affected individuals, federal or state agencies or media outlets of the incident and could result in business disruption,
negative publicity, loss of customers, potential liability, including litigation or other legal actions against us or the imposition of penalties, fines, fees or
liabilities, which may not be covered by our insurance policies, and competitive disadvantage, any or all of which would potentially adversely affect our
customer service, decrease the volume of our business and result in increased costs and lower profits. Moreover, a cybersecurity breach could require us to
devote  significant  management  resources  to  address  the  problems  associated  with  the  breach  and  to  expend  significant  additional  resources  to  upgrade
further the security measures we employ to protect information against cyber-attacks and other wrongful attempts to access such information, which could
result in a disruption of our operations.

While  we  have  invested,  and  continue  to  invest,  in  technology  security  initiatives  and  other  measures  to  prevent  security  breaches  and  cyber
incidents, as well as disaster recovery plans, these initiatives and measures may not be entirely effective to insulate us from technology disruption that could
result in adverse effects on our results of operations.

We may in the future be a party to intellectual property litigation or administrative proceedings that could be costly and could interfere with our ability
to sell our Lumivascular platform products.

The  medical  device  industry  has  been  characterized  by  extensive  litigation  regarding  patents,  trademarks,  trade  secrets,  and  other  intellectual
property rights, and companies in the industry have used intellectual property litigation to gain a competitive advantage. It is possible that U.S. and foreign
patents  and  pending  patent  applications  or  trademarks  controlled  by  third  parties  may  be  alleged  to  cover  our  products,  or  that  we  may  be  accused  of
misappropriating  third  parties’  trade  secrets.  Additionally,  our  products  include  hardware  and  software  components  that  we  purchase  from  vendors,  and
may include design components that are outside of our direct control. Our competitors, many of which have substantially greater resources and have made
substantial investments in patent portfolios, trade secrets, trademarks, and competing technologies, may have applied for or obtained or may in the future
apply for or obtain, patents or trademarks that will prevent, limit or otherwise interfere with our ability to make, use, sell and/or export our products or to
use  product  names.  They  may  devote  substantial  resources  towards  obtaining  claims  that  cover  the  design  of  our  atherectomy  products  to  prevent  the
marketing and selling of competitive products. We may become a party to patent or trademark infringement or trade secret claims and litigation as a result
of these and other third-party intellectual property rights being asserted against us. The defense and prosecution of these matters are both costly and time
consuming.  Vendors  from  whom  we  purchase  hardware  or  software  may  not  indemnify  us  in  the  event  that  such  hardware  or  software  is  accused  of
infringing a third-party’s patent or trademark or of misappropriating a third-party’s trade secret.

Further,  if  such  patents,  trademarks,  or  trade  secrets  are  successfully  asserted  against  us,  this  may  harm  our  business  and  result  in  injunctions
preventing us from selling our products, license fees, damages and the payment of attorney fees and court costs. In addition, if we are found to willfully
infringe  third-party  patents  or  trademarks  or  to  have  misappropriated  trade  secrets,  we  could  be  required  to  pay  treble  damages  in  addition  to  other
penalties.  Although  patent,  trademark,  trade  secret,  and  other  intellectual  property  disputes  in  the  medical  device  area  have  often  been  settled  through
licensing or similar arrangements, costs associated with such arrangements may be substantial and could include ongoing royalties. We may be unable to
obtain necessary licenses on satisfactory terms, if at all. If we do not obtain necessary licenses, we may not be able to redesign our Lumivascular platform
products to avoid infringement.

Similarly, interference or derivation proceedings provoked by third parties or brought by the U.S. Patent and Trademark Office, or USPTO, may be
necessary to determine the priority of inventions or other matters of inventorship with respect to our patents or patent applications. We may also become
involved  in  other  proceedings,  such  as  re-examination,  inter  partes  review,  or  opposition  proceedings,  before  the  USPTO  or  other  jurisdictional  body
relating to our intellectual property rights or the intellectual property rights of others. Adverse determinations in a judicial or administrative proceeding or
failure to obtain necessary licenses could prevent us from manufacturing and selling our Lumivascular platform products or using product names, which
would have a significant adverse impact on our business.

Additionally, we may need to commence proceedings against others to enforce our patents or trademarks, to protect our trade secrets or know-how,
or to determine the enforceability, scope and validity of the proprietary rights of others. These proceedings would result in substantial expense to us and
significant diversion of effort by our technical and management personnel. We may not prevail in any lawsuits that we initiate and the damages or other
remedies awarded, if any, may not be commercially meaningful. We may not be able to stop a competitor from marketing and selling products that are the
same or similar to our products or from using product names that are the same or similar to our product names, and our business may be harmed as a result.

37

 
 
 
 
 
 
 
 
Table of Contents

We are aware of patents held by third parties that may be asserted against us in litigation that could be costly and could limit our ability to sell our
Lumivascular platform products.

We are aware of patent families related to catheter positioning, optical coherence tomography, occlusion cutting and atherectomy owned by third
parties.  With  regard  to  atherectomy  patents,  one  of  our  founders,  Dr.  John  Simpson,  founded  FoxHollow  Technologies  prior  to  founding  our  company.
FoxHollow  Technologies  developed  an  atherectomy  device  that  is  currently  sold  by  Medtronic,  and  Dr.  Simpson  and  our  Chief  Technology  Officer,
Himanshu Patel, are listed as inventors on patents covering that device that are now held by Medtronic. We are not currently aware of any claims Medtronic
has  made  or  intends  to  make  against  us  with  respect  to  Pantheris  or  any  other  product  or  product  under  development.  Because  of  a  doctrine  known  as
“assignor estoppel,” if any of Dr. Simpson’s earlier patents are asserted against us by Medtronic, we may be prevented from asserting an invalidity defense
regarding those patents, and our defense may be compromised. Medtronic has significantly greater financial resources than we do to pursue patent litigation
and could assert these patent families against us at any time. Adverse determinations in any such litigation could prevent us from manufacturing or selling
Pantheris or other products or products under development, which would significantly harm our business.

Intellectual property rights may not provide adequate protection, which may permit third parties to compete against us more effectively.

In order to remain competitive, we must develop and maintain protection of the proprietary aspects of our technologies. We rely on a combination
of patents, copyrights, trademarks, trade secret laws and confidentiality and invention assignment agreements to protect our intellectual property rights. As
of December 31, 2023, we held 64 issued and allowed U.S. patents, 1 U.S. pending provisional application, 18 U.S. utility patent applications and 3 PCT
applications pending. As of December 31, 2023, we also had 83 issued and allowed patents from outside of the United States. As of December 31, 2023, we
had 22 pending patent applications outside of the United States, including in Australia, Canada, China, Europe, India, Japan and Mexico. Our patents and
patent  applications  include  claims  covering  key  aspects  of  the  design,  manufacture  and  therapeutic  use  of  OCT  imaging  catheters,  occlusion-crossing
catheters, atherectomy devices and our imaging console. Our patent applications may not result in issued patents and our patents may not be sufficiently
broad to protect our technology. Any patents issued to us may be challenged by third parties as being invalid, or third parties may independently develop
similar  or  competing  technology  that  avoids  our  patents.  Should  such  challenges  be  successful,  competitors  might  be  able  to  market  products  and  use
manufacturing processes that are substantially similar to ours. We may not be able to prevent the unauthorized disclosure or use of our technical knowledge
or  other  trade  secrets  by  consultants,  vendors  or  former  or  current  employees,  despite  the  existence  generally  of  confidentiality  agreements  and  other
contractual restrictions. Monitoring unauthorized use and disclosure of our intellectual property is difficult, and we do not know whether the steps we have
taken to protect our intellectual property will be adequate. In addition, the laws of many foreign countries will not protect our intellectual property rights to
the same extent as the laws of the United States. Consequently, we may be unable to prevent our proprietary technology from being exploited abroad, which
could  affect  our  ability  to  expand  to  international  markets  or  require  costly  efforts  to  protect  our  technology.  To  the  extent  our  intellectual  property
protection  is  incomplete,  we  are  exposed  to  a  greater  risk  of  direct  competition.  In  addition,  competitors  could  purchase  our  products  and  attempt  to
replicate  some  or  all  of  the  competitive  advantages  we  derive  from  our  development  efforts  or  design  around  our  protected  technology.  Our  failure  to
secure, protect and enforce our intellectual property rights could substantially harm the value of our Lumivascular platform, brand and business.

We use certain open source software in all versions of our Lightbox. We may face claims from companies that incorporate open source software
into their products or from open source licensors, claiming ownership of, or demanding release of, the source code, the open source software or derivative
works that were developed using such software, or otherwise seeking to enforce the terms of the applicable open source license. These claims could result
in litigation and could require us to cease offering Lightbox unless and until we can re-engineer it to avoid infringement. This re-engineering process could
require  significant  additional  research  and  development  resources,  and  we  may  not  be  able  to  complete  it  successfully.  These  risks  could  be  difficult  to
eliminate or manage, and, if not addressed, could harm our business, financial condition and operating results.

Regulatory and Litigation Risks

If we fail to obtain and maintain necessary regulatory clearances or approvals for our Lumivascular platform products, or if clearances or approvals
for future products and indications are delayed or not issued, our commercial operations would be harmed.

Our Lumivascular platform products are medical devices that are subject to extensive regulation by FDA in the United States and by regulatory

agencies in other countries where we do business. Government regulations specific to medical devices are wide-ranging and govern, among other things:

● product design, development and manufacture;

● laboratory, preclinical and clinical testing, labeling, packaging, storage and distribution;

● pre-marketing clearance or approval;

● record keeping;

● product marketing, promotion and advertising, sales and distribution; and

● post-marketing surveillance, including reporting of deaths or serious injuries and recalls and correction and removals.

Before a new medical device, or a new intended use for, an existing product can be marketed in the United States, a company must first submit and
receive  either  510(k)  clearance  or  pre-marketing  approval  from  FDA,  unless  an  exemption  applies.  Either  process  can  be  expensive,  lengthy  and
unpredictable. We may not be able to obtain the necessary clearances or approvals or may be unduly delayed in doing so, which could harm our business.
Furthermore, even if we are granted regulatory clearances or approvals, they may include significant limitations on the indicated uses for the product, which
may limit the market for the product. Although we have obtained 510(k) clearance to market our Pantheris family of catheters for atherectomy, and our
Ocelot and Tigereye family of catheters for crossing sub and total occlusions in the peripheral vasculature, our clearance can be revoked if safety or efficacy
problems develop. Delays in obtaining clearance or approval could increase our costs and harm our revenues and growth.

In  addition,  we  are  required  to  timely  file  various  reports  with  the  FDA,  including  medical  device  reports,  or  MDRs,  if  our  devices  may  have
caused  or  contributed  to  a  death  or  serious  injury  or  malfunctioned  in  a  way  that  would  likely  cause  or  contribute  to  a  death  or  serious  injury  if  the
malfunction were to recur. If these MDRs are not filed timely, regulators may impose sanctions and sales of our products may suffer, and we may be subject
to product liability or regulatory enforcement actions, all of which could harm our business.

If  we  initiate  a  correction  or  removal  for  one  of  our  devices  to  reduce  a  risk  to  health  posed  by  the  device,  we  would  be  required  to  submit  a
publicly available Correction and Removal report to the FDA and in many cases, similar reports to other regulatory agencies. This report could be classified
by the FDA as a device recall that could lead to increased scrutiny by the FDA, other international regulatory agencies and our customers regarding the
quality  and  safety  of  our  devices.  Furthermore,  the  submission  of  these  reports  has  been  and  could  be  used  by  competitors  against  us  in  competitive
situations and cause customers to delay purchase decisions or cancel orders and would harm our reputation.

The FDA and the Federal Trade Commission, or FTC, also regulate the advertising and promotion of our products to ensure that the claims we
make are consistent with our regulatory clearances, that there are adequate and reasonable scientific data to substantiate the claims and that our promotional
labeling and advertising is neither false nor misleading in any respect. If the FDA or FTC determines that any of our advertising or promotional claims are
misleading, not substantiated or not permissible, we may be subject to enforcement actions, including Warning Letters, adverse publicity, and we may be
required to revise our promotional claims and make other corrections or restitutions.

The  FDA  and  state  authorities  have  broad  enforcement  powers.  Our  failure  to  comply  with  applicable  regulatory  requirements  could  result  in
enforcement  action  by  the  FDA  or  state  agencies,  which  may  include,  among  other  things,  harm  to  our  reputation;  fines,  injunctions,  civil  penalties,  or
criminal  prosecution;  product  replacements  or  recalls;  or  rejecting  our  requests  for  future  510(k)  clearance  or  pre-market  approval  or  withdrawal  of  a
previously granted 510(k) clearance. If any of these events were to occur, our business and financial condition would be harmed.

Material modifications to our Lumivascular platform products may require new 510(k) clearances or pre-market approvals or may require us to recall
or cease marketing our Lumivascular platform products until clearances or approvals are obtained.

Material  modifications  to  the  intended  use  or  technological  characteristics  of  our  Lumivascular  platform  products  will  require  new
510(k) clearances or pre-market approvals or require us to recall or cease marketing the modified devices until these clearances or approvals are obtained if
such  changes  were  made  via  the  “Letter-to-File”  process  of  internal  documentation.  Based  on  published  FDA  guidelines,  the  FDA  requires  device
manufacturers to initially make and document a determination of whether or not a modification requires a new approval, supplement or clearance; however,
the  FDA  can  review  a  manufacturer’s  decision.  Any  modification  to  an  FDA-cleared  device  that  would  significantly  affect  its  safety  or  efficacy  or  that
would constitute a major change in its intended use would require a new 510(k) clearance or possibly a pre-market approval. We may not be able to obtain
additional  510(k)  clearances  or  pre-market  approvals  for  new  products  or  for  modifications  to,  or  additional  indications  for,  our  Lumivascular  platform
products in a timely fashion, or at all. Delays in obtaining required future clearances would harm our ability to introduce new or enhanced products in a
timely manner, which in turn would harm our future growth. We have made modifications to our Lumivascular platform products in the past and will make
additional modifications in the future that we believe do not or will not require additional clearances or approvals. If the FDA disagrees and requires new
clearances  or  approvals  for  the  modifications,  we  may  be  required  to  recall  and  to  stop  selling  or  marketing  our  Lumivascular  platform  products  as
modified,  which  could  harm  our  operating  results  and  require  us  to  redesign  our  Lumivascular  platform  products.  In  these  circumstances,  we  may  be
subject  to  significant  enforcement  actions.  Future  versions  of  are  Lumivascular  platform  incorporating  enhancements  may  require  additional  regulatory
clearances or approvals.

Our ability to market our current products in the United States is limited to use in peripheral vessels, and if we want to market our products for other
uses, we will need to file for FDA clearances or approvals and may need to conduct trials to support expanded use, which would be expensive, time-
consuming and may not be successful.

Our current products are cleared in the United States only for crossing sub-total and chronic total occlusions and for performing atherectomy in the
peripheral  vasculature.  These  FFDCA  clearances  prohibits  us  from  marketing  or  advertising  our  products  for  any  other  indication  within  the  peripheral
vasculature,  which  restricts  our  ability  to  sell  these  products  and  could  affect  our  growth.  Additionally,  our  products  are  contraindicated  for  use  in  the
cerebral, carotid, coronary, iliac, and renal arteries. While off-label use of medical devices is common and the FDA does not regulate physicians’ choice of
treatments, the FDA does restrict a manufacturer’s communications regarding such off-label use. We are not allowed to actively promote or advertise our
products for off-label use. In addition, we cannot make comparative claims regarding the use of our products against any alternative treatments without
conducting head-to-head comparative clinical studies, which would be expensive and time consuming. If our promotional activities fail to comply with the
FDA’s regulations or guidelines, we may be subject to warnings or enforcement action by the FDA and other government agencies. In the future, if we want
to market a variation of Ocelot, Tigereye or Pantheris product families in the United States for use in other applications for which we do not currently have
clearance, such as the coronary arteries, we will need to make modifications to these products, conduct further clinical trials and obtain new clearances or
approvals from the FDA. There can be no assurance that we will successfully develop these modifications, that future clinical studies will be successful or
that the expense of these activities will be offset by additional revenues.

If our clinical trials are unsuccessful or significantly delayed, or if we do not complete our clinical trials, our business may be harmed.

Clinical development is a long, expensive, and uncertain process and is subject to delays and the risk that products may ultimately prove unsafe or
ineffective in treating the indications for which they are designed. Completion of clinical trials may take several years or more and failure of the trial can
occur  at  any  time.  We  cannot  provide  any  assurance  that  our  clinical  trials  will  meet  their  primary  endpoints  or  that  such  trials  or  their  results  will  be
accepted  by  the  FDA  or  foreign  regulatory  authorities.  Even  if  we  achieve  positive  early  or  preliminary  results  in  clinical  trials,  these  results  do  not
necessarily predict final results, and positive results in early trials may not indicate success in later trials. Many companies in the medical device industry
have suffered significant setbacks in late-stage clinical trials, even after receiving promising results in earlier trials or in the preliminary results from these
late-stage clinical trials.

We  may  experience  numerous  unforeseen  events  during,  or  because  of,  the  clinical  trial  process  that  could  delay  or  prevent  us  from  receiving

regulatory clearance or approval for new products or modifications of existing products, including new indications for existing products, including:

● negative or inconclusive results that may cause us to decide, or regulators may require us, to conduct additional clinical and/or preclinical testing

which may be expensive and time consuming;

● trial results that do not meet the level of statistical significance required by the FDA or other regulatory authorities;

● findings by the FDA or similar foreign regulatory authorities that the product is not sufficiently safe for investigational use in humans;

● interpretations of data from preclinical testing and clinical testing by the FDA or similar foreign regulatory authorities that may be different from

our own;

● delays or failure to obtain approval of our clinical trial protocols from the FDA or other regulatory authorities;

● delays in obtaining institutional review board approvals or government approvals to conduct clinical trials at prospective sites;

● findings by the FDA or similar foreign regulatory authorities that our or our suppliers’ manufacturing processes or facilities are unsatisfactory;

● changes in the review policies of the FDA or similar foreign regulatory authorities or the adoption of new regulations that may negatively affect or

delay our ability to bring a product to market or receive approvals or clearances to treat new indications;

● trouble in managing multiple clinical sites;

● delays in agreeing on acceptable terms with third-party research organizations and trial sites that may help us conduct the clinical trials; and

● the suspension or termination by us, or regulators, of our clinical trials because the participating patients are being exposed to unacceptable health

risks.

Failures or perceived failures in our clinical trials will delay and may prevent our product development and regulatory approval process, damage

our business prospects and negatively affect our reputation and competitive position.

From time to time, we engage outside parties to perform services related to certain of our clinical studies and trials, and any failure of those parties to
fulfill their obligations could increase costs and cause delays.

From  time  to  time,  we  engage  consultants  to  help  design,  monitor,  and  analyze  the  results  of  certain  of  our  clinical  studies  and  trials.  The
consultants we engage interact with clinical investigators to enroll patients in our clinical trials. We depend on these consultants and clinical investigators to
help facilitate the clinical studies and trials and monitor and analyze data from these studies and trials under the investigational plan and protocol for the
study  or  trial  and  in  compliance  with  applicable  regulations  and  standards,  commonly  referred  to  as  good  clinical  practices.  We  may  face  delays  in  our
regulatory  approval  process  if  these  parties  do  not  perform  their  obligations  in  a  timely,  compliant  or  competent  manner.  If  these  third  parties  do  not
successfully carry out their duties or meet expected deadlines, or if the quality, completeness or accuracy of the data they obtain is compromised due to the
failure to adhere to our clinical trial protocols or for other reasons, our clinical studies or trials may be extended, delayed or terminated or may otherwise
prove to be unsuccessful, and we may have to conduct additional studies, which would significantly increase our costs, in order to obtain the regulatory
clearances that we need to commercialize our products.

We  have  limited  long-term  data  regarding  the  safety  and  efficacy  of  our  Lumivascular  platform  products.  Any  long-term  data  that  is  generated  by
clinical trials involving our Lumivascular platform may not be positive or consistent with our short-term data, which would harm our ability to obtain
clearance to market and sell our products.

Our Lumivascular platform is a novel system, and our success depends on its acceptance by the medical community as being safe and effective,
and improving clinical outcomes. Important factors upon which the efficacy of our Lumivascular platform products, including Pantheris, will be measured
are long-term data on the rate of restenosis following our procedure, and the corresponding duration of patency, or openness of the artery, and publication of
that data in peer-reviewed journals. Another important factor that physicians will consider is the rate of reintervention, or retreatment, following the use of
our Lumivascular platform products. The long-term clinical benefits of procedures that use our Lumivascular platform products are not known.

The  results  of  short-term  clinical  experience  of  our  Lumivascular  platform  products  do  not  necessarily  predict  long-term  clinical  benefit.
Restenosis rates typically increase over time. We believe that physicians will compare the rates of long-term restenosis and reintervention for procedures
using our Lumivascular platform products against alternative procedures, such as angioplasty, stenting, bypass surgery and other atherectomy procedures. If
the  long-term  rates  of  restenosis  and  reintervention  do  not  meet  physicians’  expectations,  our  Lumivascular  platform  products  may  not  become  widely
adopted and physicians may consider alternative treatments for their patients. Another significant factor that physicians will consider is acute safety data on
complications that occur during the use of our Lumivascular platform products. If the results obtained from any post-market studies that we conduct or
post-clearance surveillance indicate that the use of our Lumivascular platform products are not as safe or effective as other treatment options or as current
short-term  data  would  suggest,  adoption  of  our  product  may  suffer  and  our  business  would  be  harmed.  In  addition,  we  are  responsible  for  the  costs
associated with conducting studies to obtain safety and efficacy data. If we are unable to obtain sufficient financing, whether through our operations or from
third parties, we will not be able to conduct the studies necessary to obtain long-term data regarding the safety and efficacy of our products.

Even if we believe the data collected from clinical studies or clinical experience indicate positive results, each physician’s actual experience with our
products  will  vary.  Physicians  who  are  technically  proficient  participate  in  our  clinical  trials  and  are  high-volume  users  of  our  Lumivascular  platform
products.  Consequently,  the  results  of  our  clinical  trials  and  their  experiences  using  our  products  may  lead  to  better  patient  outcomes  than  those  of
physicians that are less proficient, perform fewer procedures or who use our products infrequently.

If we or our suppliers fail to comply with the FDA’s QSR, our manufacturing operations could be delayed or shut down and Lumivascular platform
sales could suffer.

Our manufacturing processes and those of our third-party suppliers are required to comply with the FDA’s QSR, which covers the procedures and
documentation  of  the  design,  testing,  production,  control,  quality  assurance,  labeling,  packaging,  storage  and  shipping  of  our  Lumivascular  platform
products. We are also subject to similar state requirements and licenses. In addition, we must engage in extensive recordkeeping and reporting and must
make  available  our  manufacturing  facilities  and  records  for  periodic  unannounced  inspections  by  governmental  agencies,  including  the  FDA,  state
authorities and comparable agencies in other countries. If we fail a QSR inspection, our operations could be disrupted and our manufacturing interrupted.
Failure to take adequate corrective action in response to an adverse QSR inspection could result in, among other things, a shut-down of our manufacturing
operations,  significant  fines,  suspension  of  marketing  clearances  and  approvals,  seizures  or  recalls  of  our  device,  operating  restrictions  and  criminal
prosecutions, any of which would cause our business to suffer. Furthermore, our key component suppliers may not currently be or may not continue to be in
compliance with applicable regulatory requirements, which may result in manufacturing delays for our products and cause our revenues to decline.

We have registered with the FDA as a medical device manufacturer and have obtained a manufacturing license from the CDPH. The FDA has
broad post-market and regulatory enforcement powers. We are subject to unannounced inspections by the FDA and the Food and Drug Branch of CDPH to
determine our compliance with the QSR and other regulations, and these inspections may include the manufacturing facilities of our suppliers. We have
undergone numerous audits, inspections, and reviews by the FDA, CDPH, and BSI, our European Notified Body, in the past, some of which resulted in the
identification of instances of non-compliance which we were required to correct. We expect that we will undergo additional audits, inspections, and reviews
in the future, which could result in further corrective actions.

We  can  provide  no  assurance  that  we  will  continue  to  remain  in  substantial  compliance  with  the  QSR.  If  the  FDA,  CDPH  or  BSI  inspect  our
facility  and  discover  major  compliance  problems,  we  may  have  to  shut  down  our  facility  and  cease  manufacturing  until  we  can  take  the  appropriate
remedial  steps  to  correct  the  audit  findings.  Taking  corrective  action  may  be  expensive,  time  consuming  and  a  distraction  for  management  and  if  we
experience a shutdown or delay at our manufacturing facility, we may be unable to produce our Lumivascular platform products, which would harm our
business.

Our Lumivascular platform products may in the future be subject to product recalls that could harm our reputation.

FDA and similar governmental authorities in other countries have the authority to require the recall of commercialized products in the event of
material regulatory deficiencies or defects in design or manufacture. A government mandated or voluntary recall by us could occur as a result of component
failures,  manufacturing  errors  or  design  or  labeling  defects.  Recalls  of  our  Lumivascular  platform  products  or  products  we  commercialize  in  the  future
would divert managerial attention, be expensive, harm our reputation with customers and harm our financial condition and results of operations. A recall
announcement would negatively affect our stock price.

Changes  in  coverage  and  reimbursement  for  procedures  using  our  Lumivascular  platform  products  could  affect  the  adoption  of  our  Lumivascular
platform and our future revenues.

Currently, our Lumivascular platform procedure is typically reimbursed by third-party payors, including Medicare and private healthcare insurance
companies, under existing reimbursement codes. These payors may change their coverage and reimbursement policies, as well as payment amounts, in a
way  that  would  prevent  or  limit  reimbursement  for  our  products,  which  would  significantly  harm  our  business.  Also,  healthcare  reform  legislation  or
regulation may be proposed or enacted in the future, which may adversely affect such policies and amounts. We cannot predict whether and to what extent
existing coverage and reimbursement will continue to be available. If physicians, hospitals and other providers are unable to obtain adequate coverage and
reimbursement  for  procedures  performed  using  our  Lumivascular  platform  products,  they  are  significantly  less  likely  to  use  our  Lumivascular  platform
products and our business would be harmed.

Healthcare reform measures could hinder or prevent our planned products’ commercial success.

In the United States, there have been, and we expect there will continue to be, a number of legislative and regulatory changes to the healthcare
system in ways that could harm our future revenues and profitability and the future revenues and profitability of our potential customers. Federal and state
lawmakers regularly propose and, at times, enact legislation that would result in significant changes to the healthcare system, some of which are intended to
contain or reduce the costs of medical products and services. The current presidential administration and Congress may continue to attempt broad sweeping
changes to the current healthcare laws. We face uncertainties that might result from modifications or repeal of any of the provisions of the Affordable Care
Act,  including  as  a  result  of  current  and  future  executive  orders  and  legislative  actions.  The  impact  of  those  changes  on  us  and  potential  effect  on  the
medical device industry as a whole is currently unknown. Any changes to the Affordable Care Act are likely to have an impact on our results of operations
and may have a material adverse effect on our results of operations. We cannot predict what other healthcare programs and regulations will ultimately be
implemented at the federal or state level or the effect of any future legislation or regulation in the United States may have on our business.

The continuing efforts of the government, insurance companies, managed care organizations and other payors of healthcare services to contain or

reduce costs of healthcare may harm:

● our ability to set a price that we believe is fair for our products;

● our ability to generate revenues and achieve or maintain profitability; and

● the availability of capital.

If  we  fail  to  comply  with  healthcare  regulations,  we  could  face  substantial  penalties  and  our  business,  operations  and  financial  condition  could  be
adversely affected.

Even  though  we  do  not  and  will  not  control  referrals  of  healthcare  services  or  bill  directly  to  Medicare,  Medicaid  or  other  third-party  payors,
certain federal and state healthcare laws and regulations pertaining to fraud and abuse and patients’ rights are and will be applicable to our business. We are
subject to many healthcare fraud and abuse and patient privacy regulations by both the federal government and the states in which we conduct our business.
The regulations that affect how we operate include:

● the federal healthcare program Anti-Kickback Statute, which prohibits, among other things, any person from knowingly and willfully offering,
soliciting, receiving or providing remuneration, directly or indirectly, in exchange for or to induce either the referral of an individual for, or the
purchase,  order  or  recommendation  of,  any  good  or  service  for  which  payment  may  be  made  under  federal  healthcare  programs,  such  as  the
Medicare and Medicaid programs;

● the federal False Claims Act, which prohibits, among other things, individuals or entities from knowingly presenting, or causing to be presented,

false claims, or knowingly using false statements, to obtain payment from the federal government;

● federal criminal laws that prohibit executing a scheme to defraud any healthcare benefit program or making false statements relating to healthcare

matters;

● the  Sunshine  Act,  created  under  the  Affordable  Care  Act,  and  its  implementing  regulations,  which  require  manufacturers  of  drugs,  medical
devices, biologicals and medical supplies for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program
to report annually to the HHS information related to payments or other transfers of value made to physicians and teaching hospitals, as well as
ownership and investment interests held by physicians and their immediate family members;

● HIPAA, as amended by the HITECH Act, which protects the security and privacy of protected health information; and

● state  law  equivalents  of  each  of  the  above  federal  laws,  such  as  anti-kickback  and  false  claims  laws  which  may  apply  to  items  or  services

reimbursed by any third-party payor, including commercial insurers.

The Affordable Care Act, among other things, amends the intent requirement of the Federal Anti-Kickback Statute and criminal healthcare fraud
statutes. A person or entity no longer needs to have actual knowledge of this statute or specific intent to violate it. In addition, the Affordable Care Act
provides that the government may assert that a claim including items or services resulting from a violation of the Federal Anti-Kickback Statute constitutes
a false or fraudulent claim for purposes of the False Claims Act.

Efforts  to  ensure  that  our  business  arrangements  will  comply  with  applicable  healthcare  laws  may  involve  substantial  costs.  It  is  possible  that
governmental and enforcement authorities will conclude that our business practices do not comply with current or future statutes, regulations or case law
interpreting applicable fraud and abuse or other healthcare laws and regulations. If any such actions are instituted against us, and we are not successful in
defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal and
administrative penalties, damages, disgorgement, monetary fines, possible exclusion from participation in Medicare, Medicaid and other federal healthcare
programs, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations, any of which could harm our
ability to operate our business and our results of operations. In addition, the clearance or approval and commercialization of any of our products outside the
United States will also likely subject us to foreign equivalents of the healthcare laws mentioned above, among other foreign laws.

Compliance with environmental laws and regulations could be expensive. Failure to comply with environmental laws and regulations could subject us
to significant liability.

Our research and development and manufacturing operations involve the use of hazardous substances and are subject to a variety of federal, state,
local  and  foreign  environmental  laws  and  regulations  relating  to  the  safe  storage,  use,  discharge,  disposal,  remediation  of,  and  human  exposure  to,
hazardous substances and the sale, labeling, collection, recycling, treatment and disposal of products containing hazardous substances, such as isopropyl
alcohol and other solvents. In addition, our research and development may acquire biological waste materials, such as human and animal tissue, for the sole
use of product design testing. Upon completion of the product testing, these biological wastes are safely disposed of following all federal, state, local and
foreign environmental laws and regulations. These operations are permitted by regulatory authorities, and the resultant waste materials are disposed of in
material  compliance  with  environmental  laws  and  regulations.  Liability  under  environmental  laws  and  regulations  can  be  joint  and  several  and  without
regard  to  fault  or  negligence.  Compliance  with  environmental  laws  and  regulations  may  be  expensive  and  non-compliance  could  result  in  substantial
liabilities, fines and penalties, personal injury and third-party property damage claims and substantial investigation and remediation costs. Environmental
laws  and  regulations  could  become  more  stringent  over  time,  imposing  greater  compliance  costs  and  increasing  risks  and  penalties  associated  with
violations. We cannot assure you that violations of these laws and regulations will not occur in the future or have not occurred in the past as a result of
human error, accidents, equipment failure or other causes. The expense associated with environmental regulation and remediation could harm our financial
condition and operating results.

The use, misuse or off-label use of the products in our Lumivascular platform may result in injuries that lead to product liability suits, which could be
costly to our business.

We require limited training in the use of our Lumivascular platform products because we market primarily to physicians who are experienced in
the interventional techniques required to use our device. If demand for our Lumivascular platform continues to grow, less experienced physicians will likely
use  the  devices,  potentially  leading  to  more  injury  and  an  increased  risk  of  product  liability  claims.  The  use  or  misuse  of  our  Lumivascular  platform
products has in the past resulted, and may in the future result, in complications, including damage to the treated artery, infection, internal bleeding, and limb
loss, potentially leading to product liability claims. Our Lumivascular platform products are contraindicated for use in the carotid, cerebral, iliac, or renal
arteries. Our sales force does not promote the use of our products for off-label indications, and our U.S. instructions for use specify that our Lumivascular
platform products are not intended for use in the carotid, cerebral, coronary, iliac or renal arteries. However, we cannot prevent a physician from using our
Lumivascular platform products for these off-label applications. The application of our Lumivascular platform products to coronary arteries, as opposed to
peripheral arteries, is more likely to result in complications that have serious consequences. For example, if excised plaque were not captured properly in
our device, it could be carried by the bloodstream to a narrower location, blocking a coronary artery, leading to a heart attack, or blocking an artery to the
brain, leading to a stroke. If our Lumivascular platform products are defectively designed, manufactured or labeled, contain defective components or are
misused,  we  may  become  subject  to  costly  litigation  initiated  by  our  customers  or  their  patients.  Product  liability  claims  are  especially  prevalent  in  the
medical device industry and could harm our reputation, divert management’s attention from our core business, be expensive to defend and may result in
sizable damage awards against us. Although we maintain product liability insurance, the amount or breadth of our coverage may not be adequate for the
claims that are made against us.

The  expense  and  potential  unavailability  of  insurance  coverage  for  liabilities  resulting  from  our  products  could  harm  us  and  our  ability  to  sell  our
Lumivascular platform products.

We may not have sufficient insurance coverage for future product liability claims. We may not be able to obtain insurance in amounts or scope
sufficient to provide us with adequate coverage against all potential liabilities. Any product liability claims brought against us, with or without merit, could
increase our product liability insurance rates or prevent us from securing continuing coverage, harm our reputation in the industry, significantly increase our
expenses, and reduce product sales. Product liability claims in excess of our insurance coverage would be paid out of cash reserves, harming our financial
condition and operating results.

Some of our customers and prospective customers may have difficulty in procuring or maintaining liability insurance to cover their operations and
use  of  our  Lumivascular  platform  products.  Medical  malpractice  carriers  are  also  withdrawing  coverage  in  certain  states  or  substantially  increasing
premiums. If this trend continues or worsens, our customers may discontinue using our Lumivascular platform products and potential customers may opt
against purchasing our Lumivascular platform products due to the cost or inability to procure insurance coverage.

Risks Related to Our Organizational Structure

Our stock price may be volatile, and purchasers of our common stock could incur substantial losses.

Our stock price has fluctuated significantly since our IPO and is likely to continue to fluctuate substantially. As a result of this price fluctuation,
investors may experience losses on their investments in our stock. In addition, the development stage of our operations may make it difficult for investors to
evaluate the success of our business to date and to assess our future viability. The market price for our common stock may be influenced by many factors,
including:

● sales of stock by our existing stockholders, including our affiliates;

● market acceptance of our Lumivascular platform and products;

● the results of our clinical trials;

● changes  in  analysts’  estimates,  investors’  perceptions,  recommendations  by  securities  analysts  or  our  failure  to  achieve  analysts’  and  our  own

estimates;

● the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections;

● actual or anticipated fluctuations in our financial condition and operating results;

● quarterly variations in our or our competitors’ results of operations;

● general market conditions and other factors unrelated to our operating performance or the operating performance of our competitors;

● changes in operating performance and stock market valuations of other technology companies generally, or those in the medical device industry in

particular;

● the loss of key personnel, including changes in our board of directors and management;

● legislation or regulation of our business;

● lawsuits threatened or filed against us;

● the announcement or approvals of new products or product enhancements by us or our competitors;

● announcements related to patents issued to us or our competitors and to litigation; and

● developments in our industry.

From time to time, our affiliates may sell stock for reasons due to their personal financial circumstances. These sales may be interpreted by other
stockholders  as  an  indication  of  our  performance  and  result  in  subsequent  sales  of  our  stock  that  have  the  effect  of  creating  downward  pressure  on  the
market price of our common stock. In addition, the stock prices of many companies in the medical device industry have experienced wide fluctuations that
have often been unrelated to the operating performance of those companies.

The market price and trading volume of our common stock has been volatile over the past year, and it may continue to be volatile. During the year
ended December 31, 2023, our common stock has closed as low as $2.61 and as high as $22.95 per share. We cannot predict the price at which our common
stock will trade in the future and it may decline. The price at which our common stock trades may fluctuate significantly and may be influenced by many
factors,  including  our  financial  results;  developments  generally  affecting  our  industry;  general  economic,  industry  and  market  conditions;  the  depth  and
liquidity  of  the  market  for  our  common  stock;  investor  perceptions  of  our  business;  reports  by  industry  analysts;  announcements  by  other  market
participants, including, among others, investors, our competitors, and our customers; regulatory action affecting our business; and the impact of other “Risk
Factors” discussed in this Annual Report. In addition, changes in the trading price of our common stock may be inconsistent with our operating results and
outlook. The volatility of the market price of our common stock may adversely affect investors’ ability to purchase or sell shares of our common stock.

We may fail to meet our publicly announced guidance or other expectations about our business and future operating results, which would cause our
stock price to decline.

We have provided in the past and may provide guidance in the future about our business and future operating results. In developing this guidance,
our management must make certain assumptions and judgments about our future performance, including projected revenues and the timing of regulatory
approvals.  Furthermore,  analysts  and  investors  may  develop  and  publish  their  own  projections  of  our  business,  which  may  form  a  consensus  about  our
future  performance.  Our  business  results  may  vary  significantly  from  such  guidance  or  that  consensus  due  to  a  number  of  factors,  many  of  which  are
outside  of  our  control,  and  which  could  adversely  affect  our  operations  and  operating  results.  Furthermore,  if  we  make  downward  revisions  of  our
previously announced guidance, or if our publicly announced guidance of future operating results fails to meet expectations of securities analysts, investors
or other interested parties, the price of our common stock would decline. 

If securities or industry analysts do not publish research or reports about our business, or publish negative reports about our business, our share price
and trading volume could decline.

The trading market for our common stock will depend in part on the research and reports that securities or industry analysts publish about us or our
business, our market and our competitors. We do not have any control over these analysts. The analysts who previously published research reports on our
stock following our IPO have discontinued coverage. We do not currently have analyst coverage. If analysts do not begin regularly publishing reports on us,
we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.

Sales of a substantial number of shares of our common stock in the public market, including by our existing stockholders, could cause our stock price
to fall.

Sales of a substantial number of shares of our common stock in the public market, or the perception that these sales might occur, could depress the
market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the
effect that these sales and others may have on the prevailing market price of our common stock.

We will need to raise additional funds through future equity or debt financings to meet our operational needs and capital requirements for product
development, clinical trials and commercialization. We can provide no assurance that we will be successful in raising funds pursuant to additional equity or
debt financings or that such funds will be raised at prices that do not create substantial dilution for our existing stockholders. Given our stock price, any
financing that we undertake in the future could cause substantial dilution to our existing stockholders.

On  March  28,  2022,  we  filed  a  universal  shelf  registration  statement  (the  “Shelf  Registration  Statement”)  to  offer  up  to  $50.0  million  of  our
securities, which expires on March 29, 2025. On May 20, 2022, we entered into an “at-the-market” agreement pursuant to which we may offer and sell
shares of our common stock pursuant to the Shelf Registration Statement. Due to the SEC’s “baby shelf rules,” which prohibit companies with a public
float of less than $75 million from issuing securities under a shelf registration statement in excess of one-third of such company’s public float in a twelve-
month period, we are limited in our ability to use the Shelf Registration Statement.

Our  directors  and  employees  may  sell  our  stock  through  10b5-1  trading  plans  or  in  the  market  during  open  windows  under  our  insider  trading
policy  without  such  plans  in  place.  Sales  of  our  common  stock  by  our  directors  and  employees  could  be  perceived  negatively  by  investors  or  cause
downward  pressure  on  our  common  stock  and  cause  a  reduction  in  the  price  of  our  common  stock  as  a  result.  We  have  also  registered  shares  of  our
common stock that we may issue under our employee equity incentive plans. These shares will be able to be sold freely in the public market upon issuance.

The  requirements  of  being  a  public  company  may  strain  our  resources,  divert  management’s  attention  and  affect  our  ability  to  attract  and  retain
executive management and qualified board members.

As a public company, we are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act, the
Sarbanes-Oxley Act, the Dodd-Frank Act, the listing requirements of Nasdaq and other applicable securities laws, rules and regulations. Compliance with
these laws, rules and regulations have increased our legal and financial compliance costs and will make some activities more difficult, time-consuming or
costly and increase demand on our systems and resources, particularly after we are no longer an “emerging growth company.” The Exchange Act requires,
among other things, that we file annual, quarterly and current reports with respect to our business and operating results. The Sarbanes-Oxley Act requires,
among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. In order to maintain and, if
required,  improve  our  disclosure  controls  and  procedures  and  internal  control  over  financial  reporting  to  meet  this  standard,  significant  resources  and
management  oversight  may  be  required.  Our  management  and  other  personnel  now  need  to  devote  a  substantial  amount  of  time  to  these  compliance
initiatives. As a result, management’s attention may be diverted from other business concerns and our costs and expenses will increase, which could harm
our business and operating results. We may need to hire more employees in the future or engage outside consultants to comply with these requirements,
which will increase our costs and expenses.

In addition, changing laws, regulations and standards relating to corporate governance and public disclosure are creating uncertainty for public
companies, increasing legal and financial compliance costs and making some activities more time consuming. These laws, regulations and standards are
subject to varying interpretations, in many cases due to their lack of specificity and, as a result, their application in practice may evolve over time as new
guidance  is  provided  by  regulatory  and  governing  bodies.  This  could  result  in  continuing  uncertainty  regarding  compliance  matters  and  higher  costs
necessitated  by  ongoing  revisions  to  disclosure  and  governance  practices.  We  intend  to  invest  resources  to  comply  with  evolving  laws,  regulations  and
standards,  and  this  investment  may  result  in  increased  general  and  administrative  expenses  and  a  diversion  of  management’s  time  and  attention  from
revenue-generating activities to compliance activities. If our efforts to comply with new laws, regulations and standards differ from the activities intended
by regulatory or governing bodies due to ambiguities related to their application and practice, regulatory authorities may initiate legal proceedings against
us and our business may be harmed.

We will incur additional compensation costs in the event that we decide to pay our executive officers cash compensation closer to that of executive
officers  of  other  public  medical  device  companies,  which  would  increase  our  general  and  administrative  expense  and  could  harm  our  profitability.  Any
future equity awards will also increase our compensation expense. We also expect that being a public company and compliance with applicable rules and
regulations will make it more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur
substantially higher costs to obtain coverage. These factors could also make it more difficult for us to attract and retain qualified executive officers and
members of our board of directors, particularly to serve on our audit committee and compensation committee.

As a result of disclosure of information in this Annual Report on Form 10-K and in other filings required of a public company, our business and
financial condition will become more visible, which could be advantageous to our competitors and clients and could result in threatened or actual litigation,
including by competitors and other third parties. If such claims are successful, our business and operating results could be harmed, and even if the claims
are resolved in our favor, these claims, and the time and resources necessary to resolve them, could divert the resources of our management and harm our
business and operating results.

Nasdaq may delist our securities from its exchange, which could harm our business and limit our stockholders’ liquidity.

Our common stock is currently listed on the Nasdaq Capital Market (“Nasdaq”), which has qualitative and quantitative listing criteria. However,
we cannot assure you that our common stock will continue to be listed on Nasdaq in the future. In order to continue listing our common stock on Nasdaq,
we must maintain certain financial, distribution and stock price levels. Generally, we must maintain a minimum amount in stockholders’ equity, a minimum
number of holders of our common stock and a minimum bid price.

On April 25, 2023, we received notice (the “Bid Price Deficiency Letter”) from the Listing Qualifications Department (the “Staff”) of The Nasdaq
Stock Market, LLC (“Nasdaq”) notifying us that we were not in compliance with Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Requirement”), as the
minimum bid price for our listed securities was less than $1.00 for the previous 30 consecutive business days. We had a period of 180 calendar days, or
until October 23, 2023, to regain compliance with the rule referred to in this paragraph. As part of our efforts to regain compliance with the aforementioned
rule, we effected a 1-for-15 reverse stock split on September 12, 2023.

On September 27, 2023, we received a letter from Nasdaq notifying us that the Staff had determined that the closing bid price of our common
stock had been at $1.00 per share or greater for at least 10 consecutive business days and, accordingly, that we had regained compliance with the Bid Price
Requirement. While we have regained compliance with the Bid Price Requirement, there can be no assurance that we will be able to maintain compliance
with the Bid Price Requirement, or other continued listing requirements of Nasdaq, in the future.

On  May  18,  2023,  we  received  notice  (the  “Stockholders’  Equity  Deficiency  Letter”)  from  the  Staff  that  we  no  longer  satisfy  the  $2.5  million
stockholders’ equity requirement for continued listing on The Nasdaq Capital Market, or the alternatives to that requirements – a $35 million market value
of listed securities or $500,000 in net income in the most recent fiscal year or two of the last three fiscal years – as required by Nasdaq Listing Rule 5550(b)
(the “Equity Requirement”).

As  with  the  Bid  Price  Deficiency  Letter,  the  Stockholders’  Equity  Deficiency  Letter  had  no  immediate  effect  on  our  continued  listing  on  The
Nasdaq Capital Market. In accordance with the Nasdaq Listing Rules, we were provided 45 calendar days, or until July 3, 2023, to submit a plan to regain
compliance with the Equity Requirement (the “Compliance Plan”). We submitted the Compliance Plan to Nasdaq on July 3, 2023. On July 31, 2023, we
received a letter from Nasdaq notifying us that the Staff had determined to grant us an extension of 180 calendar days from the date of the Staff’s notice, or
November 14, 2023, to regain compliance with the Equity Requirement.

On  November  21,  2023,  the  Staff  formally  notified  us  that  the  Staff  had  determined  that  we  were  unable  to  demonstrate  compliance  with  the
Equity Requirement and that our securities would be delisted at the open of business on November 30, 2023, unless we timely requested a hearing before
the Nasdaq Hearings Panel (the “Panel”). On November 28, 2023, we requested and were granted a hearing before the Panel which took place on February
20, 2024. At the hearing, we presented a plan to regain and sustain compliance with the Equity Requirement and requested an extension to do so. On March
14,  2024,  the  results  from  the  hearing  were  rendered  in  which  we  were  granted  an  extension  by  the  Panel.  This  extension  stayed  any  further  action  by
Nasdaq with respect to our continued listing until May 20, 2024.

We anticipate we will need to issue additional shares of capital stock through various other financing transactions in order to regain compliance
with the Equity Requirement. However, we may not be successful in executing such transactions on terms favorable to us, or at all. In addition, there can be
no guarantee that such efforts will succeed in helping us regain compliance with the Nasdaq Listing Rules. There can be no assurance that we will evidence
compliance within the extension period that was granted by the Panel.

If Nasdaq delists our common stock from trading on its exchange and we are not able to list our securities on another national securities exchange,
we expect our securities could be quoted on an over-the-counter market. If this were to occur, we could face significant material adverse consequences,
including:

● a limited availability of market quotations for our securities;

● reduced liquidity for our securities;

● a determination that our common stock is a “penny stock” which will require brokers trading in our common stock to adhere to more stringent

rules and possibly result in a reduced level of trading activity in the secondary trading market for our securities;

● a limited amount of news and analyst coverage; and

● a decreased ability to issue additional securities or obtain additional financing in the future.

The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of
certain  securities,  which  are  referred  to  as  “covered  securities.”  If  our  common  stock  continues  to  be  listed  on  NASDAQ,  our  common  stock  will  be  a
covered  security.  Although  the  states  are  preempted  from  regulating  the  sale  of  our  securities,  the  federal  statute  does  allow  the  states  to  investigate
companies if there is a suspicion of fraud, and, if there is a finding of fraudulent activity, then the states can regulate or bar the sale of covered securities in
a particular case.

Anti-takeover provisions in our amended and restated certificate of incorporation and bylaws and Delaware law could discourage a takeover.

Our amended and restated certificate of incorporation and bylaws contain provisions that might enable our management to resist a takeover. These

provisions include:

● a classified board of directors;

● advance notice requirements applicable to stockholders for matters to be brought before a meeting of stockholders and requirements as to the form

and content of a stockholder’s notice;

● a supermajority stockholder vote requirement for amending certain provisions of our amended and restated certificate of incorporation and bylaws;

● the right to issue preferred stock without stockholder approval, which could be used to dilute the stock ownership of a potential hostile acquirer;

● allowing stockholders to remove directors only for cause;

● a requirement that the authorized number of directors may be changed only by resolution of the board of directors;

● allowing all vacancies, including newly created directorships, to be filled by the affirmative vote of a majority of directors then in office, even if

less than a quorum, except as otherwise required by law;

● a requirement that our stockholders may only take action at annual or special meetings of our stockholders and not by written consent;

● limiting the forum for certain litigation against us to Delaware; and

● limiting the persons that can call special meetings of our stockholders to our board of directors, the chairperson of our board of directors, the chief

executive officer or the president (in the absence of a chief executive officer).

These provisions might discourage, delay or prevent a change in control of our company or a change in our management. The existence of these
provisions could adversely affect the voting power of holders of common stock and limit the price that investors might be willing to pay in the future for
shares of our common stock. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware
General  Corporation  Law,  which  generally  prohibits  a  Delaware  corporation  from  engaging  in  any  of  a  broad  range  of  business  combinations  with  any
“interested” stockholder for a period of three years following the date on which the stockholder became an “interested” stockholder.

Our  amended  and  restated  certificate  of  incorporation  provides  that  the  Court  of  Chancery  of  the  State  of  Delaware  will  be  the  sole  and  exclusive
forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for
disputes with us or our directors, officers or employees.

Our amended and restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court
of  Chancery  of  the  State  of  Delaware  is  the  sole  and  exclusive  forum  for  (i)  any  derivative  action  or  proceeding  brought  on  our  behalf,  (ii)  any  action
asserting a claim of breach of fiduciary duty owed by any of our directors, officers or other employees to us or to our stockholders, (iii) any action asserting
a claim arising pursuant to the Delaware General Corporation Law or our certificate of incorporation or bylaws (iv) any action to interpret, apply, enforce
or determine the validity of our certificate of incorporation or bylaws, or (v) any action asserting a claim governed by the internal affairs doctrine. This
exclusive forum provision would not apply to suits brought to enforce any liability or duty created by the Securities Act or the Exchange Act or any other
claim for which the federal courts have exclusive jurisdiction. To the extent that any such claims may be based upon federal law claims, Section 27 of the
Exchange  Act  creates  exclusive  federal  jurisdiction  over  all  suits  brought  to  enforce  any  duty  or  liability  created  by  the  Exchange  Act  or  the  rules  and
regulations thereunder. Furthermore, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to
enforce any duty or liability created by the Securities Act or the rules and regulations thereunder.

This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or
our directors, officers or employees, which may discourage such lawsuits against us and our directors, officers or employees. If a court were to find the
choice  of  forum  provision  contained  in  our  certificate  of  incorporation  to  be  inapplicable  or  unenforceable  in  an  action,  we  may  incur  additional  costs
associated  with  resolving  such  action  in  other  jurisdictions,  which  could  have  a  material  adverse  effect  on  our  business,  financial  condition,  results  of
operations and prospects.

We have not paid cash dividends in the past and do not expect to pay cash dividends in the future, and any return on investment may be limited to the
value of our stock.

We have never paid cash dividends and do not anticipate paying cash dividends in the foreseeable future. The payment of dividends will depend on
our  earnings,  capital  requirements,  financial  condition,  prospects  and  other  factors  our  board  of  directors  may  deem  relevant.  In  addition,  our  Loan
Agreement with CRG prohibits us from, among other things, paying any dividends or making any other distribution or payment on account of our common
stock.  The  terms  of  our  Series A  preferred  stock,  Series  B  preferred  stock  and  Series  E  preferred  stock  provide  that  we  may  not  pay  dividends  on  our
common  stock  without  concurrently  declaring  dividends  on  each.  If  we  do  not  pay  dividends,  our  stock  may  be  less  valuable  because  a  return  on  your
investment will only occur if you sell our common stock after our stock price appreciates. For more information on restrictions governing our ability to pay
dividends, see the section titled “Dividend Policy” below.

CRG has the ability to exert significant control over matters pursuant to the protective provisions therein as well as the covenants and other restrictions
in the Loan Agreement.

Our  Series  E  preferred  stock  has  protective  provisions  that  will  require  CRG  to  consent  to  certain  significant  Company  events.  For  example,
CRG’s consent would be necessary to create additional shares of Series E preferred stock, amend our organizational documents, or approve any merger,
sale of assets, or other major corporate transaction. This consent requirement could delay or prevent any acquisition of our company on terms that other
stockholders may desire, and may adversely affect the market price of our common stock.

Zylox-Tonbridge has the ability to exert significant control over our business due to their substantial interest in us, as well as their relationship with us
through the license agreement and collaboration agreement previously entered into.

In connection with their entry into the license agreement and collaboration agreement, Zylox-Tonbridge purchased securities, including common
stock and Series F preferred stock, from us representing approximately 19.9% of our outstanding voting power. If stockholder approval is obtained relating
to the conversion of the Series F preferred stock, their ownership interest could represent up to 49.9% of our outstanding voting power. In addition, we are
subject to a number of covenants and agreements under the license agreement and collaboration agreement, which could allow Zylox-Tonbridge to exercise
influence over our business.

In addition, our Series F preferred stock has protective provisions that will require Zylox-Tonbridge to consent to certain significant Company
events.  For  example,  Zylox-Tonbridge’s  consent  would  be  necessary  to  create  additional  shares  of  Series  F  preferred  stock,  amend  our  organizational
documents, or approve any merger, sale of assets, or other major corporate transaction. This consent requirement could delay or prevent any acquisition of
our company on terms that other stockholders may desire, and may adversely affect the market price of our common stock.

Zylox-Tonbridge’s  interests  may  conflict  with  your  interests  as  a  stockholder.  Zylox-Tonbridge’s  ability  to  influence  our  business  could  make
some transactions, including mergers or other changes in control, more difficult or impossible without the support of Zylox-Tonbridge and could discourage
others from making tender offers, which could prevent stockholders from receiving a premium for their shares. As a result, the market price of our common
stock may be affected.

We depend on our board of directors and the loss of one or more or our board members or an inability to attract and retain highly qualified members
could harm our business.

Our success largely depends upon the continued services and involvement of the members of our board of directors and the loss of one or more of
our directors could adversely affect us. Additionally, changes in the composition of our board resulting from the addition or departure of members could
disrupt our business.

We  must  attract  and  retain  highly  qualified  board  members.  Competition  for  these  individuals  can  be  intense.  We  have,  from  time  to  time,
experienced,  and  we  may  experience  in  the  future,  difficulty  in  adding  and  retaining  members  of  our  board  with  appropriate  qualifications.  In  addition,
some states and other regulatory authorities, including Nasdaq, have adopted board diversity requirements, which mandate that companies have a minimum
number  of  directors  who  meet  specified  diversity  criteria,  or  otherwise  require  that  companies  disclose  board  diversity  information.  If  we  are  unable  to
attract  and  retain  qualified  board  members  who  meet  such  diversity  criteria,  we  will  be  unable  to  comply  with  such  requirements  and  could  face
enforcement or other regulatory actions.

ITEM 1C.   CYBERSECURITY

Risk Management and Strategy

Because  it  is  essential  to  our  operations  and  business  strategy  that  our  website,  technology  and  network  infrastructure  remain  secure,  we  have
processes  in  place  for  assessing,  identifying,  and  managing  material  risks  from  cybersecurity  threats.  We  have  integrated  these  processes  into  our
cybersecurity risk management program.

The key processes, or components, of our cybersecurity risk management include:

● conducting periodic risk assessments to assist in identifying cybersecurity threats or risks;

● cybersecurity strategic roadmap;

● security  and  IT  infrastructure  management  team,  responsible  for  managing  our  cybersecurity  processes,  implementing  security  applications  and

protocols, monitoring and executing security or network controls, and responding to incidents or threats;

● cybersecurity training programs and cybersecurity awareness events for employees;

● incident response plan, including assessing and monitoring potential cyber threats;

● similar processes or applications to mitigate or manage cybersecurity risk from third-party service providers;

We  sometimes  engage  external  cybersecurity  experts,  or  applications,  to  enhance  our  cybersecurity  program.  These  serve  to  assist  our  internal

cybersecurity team in mitigating cyber threats, in addition to monitoring and responding to potential cyber incidents.

Additional  information  regarding  risks  from  cybersecurity  threats  is  discussed  in  Part  I,  Item  IA,  “Risk  Factors,”  under  the  heading  “If  our
technology  infrastructure  is  compromised,  damaged  or  interrupted  by  a  cybersecurity  incident,  data  security  breach  or  other  security  problems,  our
operating results and financial condition could be adversely affected,” which should be read in conjunction with the information herein.

Governance

Cybersecurity risk management is an important priority integrated into our overall governance structure. Our Board of Directors oversees risks

from cybersecurity threats and includes the involvement of the Audit Committee in the governance strategy.

Our  IT  security  management  team,  led  by  certain  key  functional  leaders  in  our  organization,  who  reports  quarterly  in  meetings  to  our  Audit
Committee and periodically to our Board of Directors regarding updates to our cybersecurity program and related risks. Topics in the meetings include
discussion of the company-wide risks, protocols to mitigate such risks, and the progress of initiatives in the cybersecurity program. Specific cybersecurity
briefing areas may include topics such as security, infrastructure, cybersecurity tooling/applications, and compliance.

ITEM 2.    PROPERTIES

The  Company’s  operating  lease  obligations  primarily  consist  of  leased  office,  laboratory,  and  manufacturing  space  under  a  non-cancelable
operating  lease  located  in  Redwood  City,  California.  In  addition  to  the  minimum  future  lease  commitments  presented  below,  the  lease  requires  the
Company to pay property taxes, insurance, maintenance, and repair costs. The lease includes a rent holiday concession and escalation clauses for increased
rent  over  the  lease  term.  Rent  expense  is  recognized  in  accordance  with  the  Financial  Accounting  Standards  Board  (“FASB”),  Accounting  Standards
Codification (“ASC”), 842, Leases, using the straight-line method over the term of the lease.

The  lease  will  expire  on  November  30,  2024.  The  Company  is  obligated  to  pay  approximately  $5.8  million  in  base  rent  payments  through

November 2024, beginning on December 1, 2019. The weighted average remaining lease term as of December 31, 2023 is 0.9 years.

On March 6, 2024, the Company entered into an amendment to the lease which extended the lease term for a period of one year, subsequent to the
original expiration of November 30, 2024. As amended, the lease will expire on November 30, 2025. Under the terms of the amendment, the Company will
be  obligated  to  pay  approximately  $1.3  million  in  base  rent  payments  through  November  2025,  beginning  on  December  1,  2024.  This  amendment  also
provides an optional one year extension of the lease following the end of the current term, as amended.

We believe that our current facilities are adequate for our current and anticipated future needs through at least 2024.

ITEM 3.    LEGAL PROCEEDINGS

We are not involved in any pending legal proceedings that we believe could have a material adverse effect on our financial condition, results of
operations or cash flows. From time to time we may be involved in legal proceedings or investigations, which could harm our reputation, business and
financial condition and divert the attention of our management from the operation of our business.

ITEM 5.    MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF
EQUITY SECURITIES

Our  common  stock  began  trading  on  the  Nasdaq  Global  Market  on  January  30,  2015  and  was  transferred  to  the  Nasdaq  Capital  Market  on

January 19, 2018, where it trades under the symbol “AVGR”.

HOLDERS OF RECORD

As of March 8, 2024, there were 1,586,434 shares of our common stock held by 128 holders of record of our common stock. The actual number of
stockholders is greater than this number of record holders, and includes stockholders who are beneficial owners, but whose shares are held in street name
by brokers and other nominees. This number of holders of record also does not include stockholders whose shares may be held in trust by other entities.

DIVIDEND POLICY

Our Series A preferred stock carried an 8% cumulative dividend, which accumulated and was compounded annually. This cumulative dividend
was payable in arrears on December 31 of each year, commencing with December 31, 2018, and at our option was payable in additional shares of Series A
preferred  stock.  Our  Series  E  preferred  stock  carries  an  8%  cumulative  dividend,  which  accumulates  and  is  compounded  annually.  This  cumulative
dividend is payable in arrears on December 31 of each year, commencing with December 31, 2024, and at our option is payable in additional shares of
Series E preferred stock or cash.

On  September  29,  2023,  the  Company  entered  into  a  Waiver  Agreement  with  CRG,  who  hold  all  of  the  outstanding  shares  of  the  Company’s
Series A and Series E preferred stock. Pursuant to the Waiver Agreement, CRG waived their rights to receive the Series A and Series E preferred dividends
for the year ending December 31, 2023. Such waived preferred dividends were not cumulative or accrued.

In  connection  with  the  strategic  collaboration,  on  March  5,  2024,  the  Company  entered  into  a  securities  purchase  agreement  with  CRG  to
exchange all outstanding shares of its Series A preferred stock for 10,000 shares of Series A-1 preferred stock. The Series A-1 preferred stock does not
accrue or pay dividends payable solely on the Series A-1 preferred stock.

On March 5, 2024, the Company entered into a stock purchase agreement which in part, resulted in the issuance of a newly authorized Series F
convertible preferred stock. Our Series F convertible preferred stock carries a 5% cumulative dividend, which accumulates and is compounded annually
until the third anniversary of their issuance date and 8% cumulative dividend, which accumulates and is compounded annually thereafter. This cumulative
dividend is payable in arrears on December 31 of each year, commencing with December 31, 2024, and at our option is payable in additional shares of
Series F convertible preferred stock or cash through the third anniversary of the issuance date and is payable in additional shares of Series F convertible
preferred stock or cash at the option of the holder thereafter.

The  terms  of  our  Series  B  preferred  stock,  Series  E  preferred  stock  and  Series  F  convertible  preferred  stock  provide  that  we  may  not  declare
dividends on the common stock without concurrently declaring dividends on such series of preferred stock in an amount equal to that payable had they been
converted to common stock prior to the dividend. We have issued a total of 19,076 shares of Series A preferred stock to pay the preferred dividend to the
holder of Series A preferred stock through December 31, 2023. Other than the preferred dividend on Series A preferred stock, we have never declared or
paid any cash dividends on any of our capital stock.

Except  with  respect  to  the  Series  E  and  Series  F  preferred  stock’s  cumulative  dividends,  we  do  not  anticipate  paying  any  dividends  in  the
foreseeable  future  and  currently  intend  to  retain  all  available  funds  and  any  future  earnings  for  use  in  the  operation  of  our  business  and  to  finance  the
growth and development of our business. Future determination as to the declaration and payment of dividends, if any, will be at the discretion of our board
of directors and will depend on then existing conditions, including our operating results, financial condition, contractual restrictions, capital requirements,
business prospects and other factors our board of directors may deem relevant. In addition, our Loan Agreement with CRG prohibits us from paying any
dividends or making any other distribution or payment on account of our common stock.

You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements

forward-looking statements that involve risks and uncertainties, such as statements of our plans, objectives, expectations and intentions, that are based on
the beliefs of our management, as well as assumptions made by, and information currently available to, our management. Our actual results could differ
materially from those discussed in these forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited
to, those discussed in the section of this Annual Report on Form 10-K entitled “Risk factors.”

Overview

We  are  a  commercial-stage  medical  device  company  that  designs,  manufactures,  and  sells  real-time  high-definition  image-guided,  minimally
invasive catheter-based systems that are used by physicians to treat patients with peripheral artery disease (“PAD”). Patients with PAD have a build-up of
plaque in the arteries that supply blood to areas away from the heart, particularly the pelvis and legs. Our mission is to significantly improve the treatment
of vascular disease through the introduction of products based on our Lumivascular platform, the only intravascular real-time high-definition image-guided
system available in this market.

We  design,  manufacture,  and  sell  a  suite  of  products  in  the  United  States  and  select  international  markets.  We  are  located  in  Redwood  City,
California. Our current Lumivascular platform consists of products including our Lightbox imaging console, the Ocelot and Tigereye family of devices,
which are image-guided devices designed to allow physicians to penetrate a total blockage in an artery, known as a chronic total occlusion (“CTO”), and the
Pantheris family of catheters, our image-guided atherectomy catheters which are designed to allow physicians to precisely remove arterial plaque in PAD
patients.

We are in the process of developing CTO crossing devices to target the coronary CTO market. However, the market for medical devices in the
coronary  artery  disease  (“CAD”)  space  is  highly  competitive,  dynamic,  and  marked  by  rapid  and  substantial  technological  development  and  product
innovation and there is no guarantee that we will be successful in developing and commercializing any new CAD product. At this stage, we are working on
understanding market requirements, and initiated the development process for the new CAD product, which we anticipate will require additional expenses.

We obtained CE Marking for our original Ocelot product in September 2011 and received from the U.S. Food and Drug Administration (“FDA”),
510(k) clearance in November 2012. We also received 510(k) clearance from the FDA for commercialization of Pantheris in October 2015. We received an
additional 510(k) clearance for an enhanced version of Pantheris in March 2016 and commenced sales of Pantheris in the United States and select European
countries promptly thereafter. In May 2018, we received 510(k) clearance from the FDA for our current next-generation version of Pantheris. In April 2019,
we received 510(k) clearance from the FDA for our Pantheris Small Vessel (“SV”), a version of Pantheris targeting smaller vessels, and commenced sales
in July 2019. In September 2020, we received 510(k) clearance of Tigereye, a next-generation CTO crossing system utilizing Avinger’s proprietary image-
guided technology platform. Tigereye is a product line extension of Avinger’s Ocelot family of image-guided CTO crossing catheters. In January 2022, we
received  510(k)  clearance  from  the  FDA  for  our  Lightbox  3  imaging  console,  an  advanced  version  of  our  Lightbox  that  allows  for  easy  portability  and
offers significant reductions in size, weight, and production cost in comparison to the incumbent version.

In  April  2023,  we  received  510(k)  clearance  from  the  FDA  for  Tigereye  Spinning  Tip  (“ST”),  a  next-generation  image-guided  CTO  crossing
system. Tigereye ST is a line extension of our Ocelot and Tigereye family of CTO crossing catheters. This new image-guided catheter incorporates design
upgrades  to  the  tip  configuration  and  catheter  shaft  to  increase  crossing  power  and  procedural  success  in  challenging  lesions,  as  well  as  design
enhancements for ease of image interpretation during the procedure. The low-profile Tigereye ST has a working length of 140 cm and 5 French sheath. We
initiated a limited launch of Tigereye ST in the second quarter of 2023 and subsequently expanded to full commercial availability within the United States
during the third quarter of 2023.

In June 2023, we received 510(k) clearance from the FDA for Pantheris Large Vessel (“LV”), a next generation image guided atherectomy system
for the treatment of larger vessels, such as the superficial femoral artery (“SFA”) and popliteal arteries. Pantheris LV is a line extension of our Pantheris and
Pantheris SV family of atherectomy products. This catheter offers higher speed plaque excision for efficient removal of challenging occlusive tissue and
multiple  features  to  streamline  and  simplify  user-operation,  including  enhanced  tissue  packing  and  removal,  a  radiopaque  gauge  to  measure  volume  of
plaque excised during the procedure, and enhanced guidewire management. We initiated a limited launch of the Pantheris LV during the third quarter of
2023 and expect to expand to full commercial availability within the United States around mid-year 2024.

Current treatments for PAD, including bypass surgery, can be costly and may result in complications, high levels of post-surgery pain, and lengthy
hospital stays and recovery times. Minimally invasive, or endovascular, treatments for PAD include stenting, angioplasty, and atherectomy, which is the use
of  a  catheter-based  device  for  the  removal  of  plaque.  These  treatments  all  have  limitations  in  their  safety  or  efficacy  profiles  and  frequently  result  in
recurrence of the disease, also known as restenosis. We believe one of the main contributing factors to high restenosis rates for PAD patients treated with
endovascular technologies is the amount of vascular injury that occurs during an intervention. Specifically, these treatments often disrupt the membrane
between the outermost layers of the artery, which is referred to as the external elastic lamina (“EEL”).

We believe our Lumivascular platform is the only technology that offers radiation free, high-definition real-time visualization of the inside of the
artery during PAD treatment through the use of optical coherence tomography (“OCT”), a high resolution, light-based, radiation-free imaging technology.
Our  Lumivascular  platform  provides  physicians  with  high-definition  real-time  OCT  images  from  the  inside  of  an  artery,  and  we  believe  Ocelot  and
Pantheris  are  the  first  products  to  offer  intravascular  visualization  during  CTO  crossing  and  atherectomy,  respectively.  We  believe  this  approach  will
significantly improve patient outcomes by providing physicians with a clearer picture of the artery using radiation-free image guidance during treatment,
enabling them to better differentiate between plaque and healthy arterial structures. Our Lumivascular platform is designed to improve patient safety by
enabling physicians to direct treatment towards the plaque, while avoiding damage to healthy portions of the artery.

During  the  first  quarter  of  2015,  we  completed  enrollment  of  patients  in  VISION,  a  clinical  trial  designed  to  support  our  August  2015
510(k)  submission  to  the  FDA  for  our  Pantheris  atherectomy  device.  VISION  was  designed  to  evaluate  the  safety  and  efficacy  of  Pantheris  to  perform
atherectomy  using  intravascular  imaging  and  successfully  achieved  all  primary  and  secondary  safety  and  efficacy  endpoints.  We  believe  the  data  from
VISION allows us to demonstrate that avoiding damage to healthy arterial structures, and in particular disruption of the external elastic lamina, which is the
membrane between the outermost layers of the artery, reduces the likelihood of restenosis, or re-narrowing, of the diseased artery. Although the original
VISION study protocol was not designed to follow patients beyond six months, we worked with 18 of the VISION sites to re-solicit consent from previous
clinical trial patients in order for them to evaluate patient outcomes through 12 and 24 months following initial treatment. Data collection for the remaining
patients from participating sites was completed in May 2017, and we released the final 12- and 24-month results for a total of 89 patients in July 2017.

During the fourth quarter of 2017, we began enrolling patients in INSIGHT, a clinical trial designed to support a submission to the FDA to expand
the  indication  for  our  Pantheris  atherectomy  device  to  include  the  treatment  of  in-stent  restenosis.  Patient  enrollment  began  in  October  2017  and  was
completed in July 2021. Patient outcomes were evaluated at thirty days, six months and one year following treatment. In November 2021, we received
510(k) clearance from the FDA for this new clinical indication for treating in-stent restenosis with Pantheris using the data collected and analyzed from
INSIGHT.  We  expect  this  will  expand  our  addressable  market  for  Pantheris  to  include  a  high-incidence  disease  state  for  which  there  are  few  available
indicated or effective treatment options.

We are pursuing additional clinical data programs including a post-market study, IMAGE-BTK, that is designed to evaluate the safety and efficacy
of Pantheris SV in the treatment of PAD lesions below-the-knee. We completed enrollment during 2023. Patient outcomes are being evaluated at thirty
days, six months and one year following treatment. We expect this will bolster the application of Pantheris SV as a primary interventional tool to address
below-the-knee lesions for which there are few available effective treatment options.

We focus our direct sales force, marketing efforts and promotional activities on interventional cardiologists, vascular surgeons and interventional
radiologists. We also work on developing strong relationships with physicians and hospitals that we have identified as key opinion leaders. Although our
sales and marketing efforts are directed at these physicians because they are the primary users of our technology, we consider the hospitals and medical
centers where the procedure is performed to be our customers, as they typically are responsible for purchasing our products. We are designing additional
future  products  to  be  compatible  with  our  Lumivascular  platform,  which  we  expect  to  enhance  the  value  proposition  for  hospitals  to  invest  in  our
technology.  Pantheris  qualifies  for  existing  reimbursement  codes  currently  utilized  by  other  atherectomy  products,  further  facilitating  adoption  of  our
products.

We  have  assembled  a  team  with  extensive  medical  device  development  and  commercialization  experience  in  both  start-up  and  large,  multi-
national medical device companies. We assemble all of our catheter products at our manufacturing facility but certain critical processes, such as coating and
sterilization, are performed by outside vendors. Our Lightbox 3 imaging console is assembled through a qualified contract manufacturer. We expect our
current manufacturing facility in California, will be sufficient through at least 2024.

We generated revenues of $10.1 million in 2021, $8.3 million in 2022 and $7.7 million in 2023. Revenues during these years were tangentially
affected  by  COVID-19  as  hospitals  continued  to  defer  elective  procedures  in  certain  jurisdictions  while  increasing  volume  to  accommodate  previously
deferred  procedures  in  others,  which  among  other  things,  created  unpredictability  in  case  volume.  This  unpredictability  created  more  volatility  in  our
revenues which continued to affect our business in the aforementioned years. The decline in revenue in 2022 and 2023 was primarily attributable to the
adverse effects of staffing shortages, resource constraints on our customers as hospitals deferred elective procedures, and the impact of a very competitive
market for talent on the retention of our commercial team.

Recent Developments

Hospital Capacity and Resource Constraints Update

As a result of the effects of hospital staffing shortages, we have continued to experience significant volatility in sales, particularly as individuals, as
well as hospitals and other medical providers, deferred elective procedures in response to resource constraints and capacity issues. We have continued to
experience fluctuating sales as practitioners in certain jurisdictions were able to perform elective procedures while other jurisdictions were continuing to
experience  capacity  issues.  Hospital  staffing  shortages  have  had  and  are  likely  to  continue  to  have  adverse  impacts  on  our  business  and  results  of
operations. This situation has created a significant amount of volatility in the medical industry which makes future developments and results difficult to
predict.

We believe capacity issues and resource constraints and the related increased cost pressures and burdens on the hospital systems have had and may
continue to have an adverse effect on our ability to generate sales due to the fluctuating and unpredictable levels of capacity medical providers have to
perform procedures that require the use of our products. In addition, we have experienced disruptions in our manufacturing and supply chain, as well as
delays in site initiation and patient enrollment for our clinical studies. If we are unable to successfully complete these or other clinical studies, our business
and results of operations could be harmed.

Nasdaq Delisting Notice

On April 25, 2023, we received notice (the “Bid Price Deficiency Letter”) from the Listing Qualifications Department (the “Staff”) of The Nasdaq
Stock Market, LLC (“Nasdaq”) notifying us that we were not in compliance with Nasdaq Listing Rule 5550(a)(2) (the “Bid Price Requirement”), as the
minimum bid price for our listed securities was less than $1.00 for the previous 30 consecutive business days. We had a period of 180 calendar days, or
until October 23, 2023, to regain compliance with the rule referred to in this paragraph. As part of our efforts to regain compliance with the aforementioned
rule, we effected a 1-for-15 reverse stock split on September 12, 2023.

On September 27, 2023, we received a letter from Nasdaq notifying us that the Staff had determined that the closing bid price of our common
stock had been at $1.00 per share or greater for at least 10 consecutive business days and, accordingly, that we had regained compliance with the Bid Price
Requirement. While we have regained compliance with the Bid Price Requirement, there can be no assurance that we will be able to maintain compliance
with the Bid Price Requirement, or other continued listing requirements of Nasdaq, in the future.

On  May  18,  2023,  we  received  notice  (the  “Stockholders’  Equity  Deficiency  Letter”)  from  the  Staff  that  we  no  longer  satisfy  the  $2.5  million
stockholders’ equity requirement for continued listing on The Nasdaq Capital Market, or the alternatives to that requirements – a $35 million market value
of listed securities or $500,000 in net income in the most recent fiscal year or two of the last three fiscal years – as required by Nasdaq Listing Rule 5550(b)
(the “Equity Requirement”).

As  with  the  Bid  Price  Deficiency  Letter,  the  Stockholders’  Equity  Deficiency  Letter  had  no  immediate  effect  on  our  continued  listing  on  The
Nasdaq Capital Market. In accordance with the Nasdaq Listing Rules, we were provided 45 calendar days, or until July 3, 2023, to submit a plan to regain
compliance with the Equity Requirement (the “Compliance Plan”). We submitted the Compliance Plan to Nasdaq on July 3, 2023. On July 31, 2023, we
received a letter from Nasdaq notifying us that the Staff had determined to grant us an extension of 180 calendar days from the date of the Staff’s notice, or
November 14, 2023, to regain compliance with the Equity Requirement.

On  November  21,  2023,  the  Staff  formally  notified  us  that  the  Staff  had  determined  that  we  were  unable  to  demonstrate  compliance  with  the
Equity Requirement and that our securities would be delisted at the open of business on November 30, 2023, unless we timely requested a hearing before
the Nasdaq Hearings Panel (the “Panel”). On November 28, 2023, we requested and were granted a hearing before the Panel which took place on February
20, 2024. At the hearing, we presented a plan to regain and sustain compliance with the Equity Requirement and requested an extension to do so. On March
14,  2024,  the  results  from  the  hearing  were  rendered  in  which  we  were  granted  an  extension  by  the  Panel.  This  extension  stayed  any  further  action  by
Nasdaq with respect to our continued listing until May 20, 2024.

Table of Contents

We are taking definitive steps pursuant to our plan as presented to the Panel to ensure our compliance with the Equity Rule and all other applicable
criteria  for  continued  listing  on  Nasdaq.  We  have  already  undertaken  certain  actions  such  as  converting  outstanding  indebtedness  into  equity,  issuing
additional shares of capital stock and obtaining waivers of dividends to holders of certain classes of our preferred stock for the year ended December 31,
2023.  In  March  2024,  we  also  entered  into  a  securities  purchase  agreement  as  part  of  a  larger  strategic  partnership  and  collaboration  transaction
representing  entry  into  a  number  of  financing,  licensing  and  other  agreements  (“Strategic  Collaboration”)  in  which  we  received  gross  proceeds  of  $7.5
million and expect to receive another $7.5 million upon the successful completion of certain milestones, discussed in more detail below. This financing
transaction was an integral part of the plan presented to the Panel.

We anticipate we will need to issue additional shares of capital stock through various other financing transactions in order to regain compliance
with the Equity Requirement. However, we may not be successful in executing such transactions on terms favorable to us, or at all. In addition, there can be
no guarantee that such efforts will succeed in helping us regain compliance with the Nasdaq Listing Rules. There can be no assurance that we will evidence
compliance within the extension period that was granted by the Panel.

Global Supply Chain

We  are  closely  monitoring  the  general  economic  conditions  on  global  supply  chain,  manufacturing,  and  logistics  operations.  As  inflationary
pressures increase, we anticipate that our production and operating costs may similarly increase, including costs and availability of materials and labor. In
addition, port closures and labor shortages have resulted in manufacturing and shipping constraints generally. While we have had sufficient inventory on-
hand to meet our current production requirements and customer demand, we have experienced some constraints with respect to the availability of certain
materials and extended lead times from certain key suppliers. We have also experienced some delays in shipping products to our customers. Any significant
delay or interruption in our supply chain could impair our ability to meet the demands of our customers in the future and could harm our business.

We may need to identify and qualify new suppliers in response to disruptions and difficulties experienced by some of our current suppliers. The
process of identifying and qualifying suppliers is lengthy with no guarantee of ultimately mitigating the current issues we are experiencing. This process
can include but is not limited to delays in qualification, quality issues on components, and higher costs to source these components. All of these issues may
impair our ability to meet the demands of our customers in the future.

Reverse Stock Split

On March 11, 2022, our board of directors approved an amendment to our amended and restated certificate of incorporation to effect a 1-for-20

reverse stock split of our issued and outstanding common stock. The reverse stock split became effective on March 14, 2022.

On September 11, 2023, our board of directors approved an amendment to our amended and restated certificate of incorporation to effect a 1-for-
15 reverse stock split of our issued and outstanding common stock. The reverse stock split became effective on September 12, 2023. The par value of the
common stock was not adjusted as a result of the reverse stock splits. All common stock, stock options, restricted stock units, and per share amounts in the
financial statements have been retroactively adjusted for all periods presented to give effect to the reverse stock splits.

Strategic Collaboration

On March 4, 2024, we entered into a License and Distribution Agreement (the “License Agreement”) with Zylox-Tonbridge, pursuant to which we
will license and distribute certain of our products (including consumables) in the Greater China region, including mainland China, Hong Kong, Macao, and
Taiwan (the “Territory”). Zylox-Tonbridge will lead all regulatory activities for the registration of our products in the Territory. We will also license our
intellectual  property  and  know-how  related  to  our  products  to  Zylox-Tonbridge  so  that  Zylox-Tonbridge  can  manufacture  the  localized  products  in  the
Territory. All  sales  of  our  products  locally  manufactured  by  Zylox-Tonbridge  with  regulatory  approval  by  the  regulatory  authorities  in  the  Territory  and
commercialized  in  the  Territory  will  be  royalty  bearing  to  us  at  varying  percentages  depending  on  the  amount  of  gross  revenue  and  product  gross
margin.         

In connection with the License Agreement, we also entered into a Strategic Cooperation and Framework Agreement with Zylox-Tonbridge (the
“Collaboration  Agreement”  and,  together  with  the  License  Agreement,  the  “Strategic  Collaboration”),  which  provides  the  opportunity  for  us  to  access
certain Zylox-Tonbridge peripheral vascular products for distribution in the U.S. and Germany. The agreement also provides the option for us to source
finished goods inventory from Zylox-Tonbridge following registration of Zylox-Tonbridge’s manufacturing facility with the FDA.

Financing Agreements

On  March  4,  2024,  in  connection  with  the  Strategic  Collaboration,  we  and  Zylox-Tonbridge  Medical  Limited,  a  wholly-owned  subsidiary  of
Zylox-Tonbridge (the “Purchaser”), entered into a Securities Purchase Agreement (the “Purchase Agreement”), pursuant to which the Purchaser agreed to
purchase, in two tranches, up to an aggregate of $15 million in shares of our common stock, par value $0.001 per share (the “Common Stock”), and shares
of two new series of our preferred stock (the “Private Placement”). On March 5, 2024, (the “Initial Closing”), we issued to the Purchaser 75,327 shares of
the Common Stock at a purchase price per share of $3.664 (the “Purchase Price”), and 7,224 shares of a newly authorized Series F convertible preferred
stock, par value $0.001 per share (the “Series F Preferred Stock”), at a purchase price per share of $1,000, for an aggregate purchase price of $7.5 million.

Each share of Series F Preferred Stock has a stated value of $1,000 and is initially convertible into approximately 273 shares of Common Stock at
a conversion price equal to the Purchase Price, subject to the terms of the Certificate of Designation of Preferences, Rights, and Limitations of the Series F
Preferred Stock (the “Series F Certificate of Designation”).

Upon completion of the following as mutually agreed upon by us and the Purchaser: (i) the successful registration and listing under 21 CFR part
807 with the FDA of the Purchaser and one of its designated affiliates to manufacture our products, and (ii) us achieving an aggregate of $10 million in
gross revenue within any four consecutive fiscal quarters after the Initial Closing, excluding any gross revenue achieved by us under the License Agreement
discussed above (together, the “Milestones”), the Purchaser will invest an additional $7.5 million (the “Milestone Closing”) to purchase shares our new
Series G convertible preferred stock, par value $0.001 per share (the “Series G Preferred Stock”). Each share of Series G Preferred Stock will have a stated
value of $1,000 and will be convertible into shares of Common Stock at a conversion price of equal to the lowest of (x) the Purchase Price, (y) the closing
price of the Common Stock on the date immediately preceding the Milestone Closing, and (z) the average of the closing price for the last five trading days
preceding the Milestone Closing, provided that the conversion price will be no less than $0.20.

Our obligations to (i) accept conversion of the shares of Series F Preferred Stock in excess of 19.99% of our outstanding common stock as of the
date of the Purchase Agreement and (ii) issue and sell shares of Series G Preferred Stock upon completion of the Milestones are each subject to receipt of
the approval of our stockholders as is necessary under the rules and regulations of Nasdaq (including, without limitation, Nasdaq Rule 5635(d)).

Series A Preferred Stock Exchange

In connection with the Strategic Collaboration and the Private Placement, on March 5, 2024, we entered into a Securities Purchase Agreement (the
“A-1 Securities Purchase Agreement”) to exchange all outstanding shares of its Series A Preferred Stock for 10,000 shares of Series A-1 Preferred Stock
(the “Exchange”). Among other things, the shares of Series A-1 Preferred Stock: (i) are convertible into an aggregate of approximately 2,729,257 shares of
Common Stock at a conversion price equal to the Purchase Price, (ii) do not accrue or pay dividends payable solely on the Series A-1 Preferred Stock, (iii)
will  have  no  liquidation  preference  and  (iv)  will  be  junior  in  rank  to  shares  of  the  our  Series  E  Preferred  Stock,  Series  F  Preferred  Stock  and  Series  G
Preferred Stock.

CRG Loan Amendment

In  connection  with  the  Strategic  Collaboration  and  the  Private  Placement,  we  also  agreed  to  enter  into  Amendment  No.  9  to  Loan  Agreement
effective  as  of  the  Initial  Closing  with  CRG,  which  amends  the  Loan  Agreement  to,  among  other  things:  (i)  extend  the  interest-only  period  through
December 31, 2026; (ii) provide that interest payable through December 31, 2026 may be payable in kind rather than in cash; and (iii) permit the payment
of dividends on the preferred stock issued or issuable to the Purchaser.

Lease Extension

On March 6, 2024, we entered into an amendment to the lease which extended the lease term for a period of one year, subsequent to the original
expiration of November 30, 2024. As amended, the lease will expire on November 30, 2025. Under the terms of the amendment, we will be obligated to
pay approximately $1.3 million in base rent payments through November 2025, beginning on December 1, 2024. This amendment also provides an optional
one year extension of the lease following the end of the current term, as amended.

Financing

During the years ended December 31, 2023 and 2022, our net loss and comprehensive loss was $18.3 million and $17.6 million, respectively. We
have not been profitable since inception, and as of December 31, 2023, our accumulated deficit was $420.7 million. Since inception, we have financed our
operations primarily through private and public placements of our preferred and common securities and, to a lesser extent, debt financing arrangements.

In September 2015, we entered into a Term Loan Agreement (the “Loan Agreement”) with CRG Partners III L.P. and certain of its affiliated funds
(collectively, “CRG”), under which we were able to borrow up to $50.0 million on or before the end of the twenty-four (24) month period commencing on
the  first  Borrowing  Date  (as  defined  in  the  Loan  Agreement),  subject  to  certain  terms  and  conditions.  Under  the  Loan  Agreement  we  borrowed  $30.0
million  on  September  22,  2015  and  an  additional  $10.0  million  on  June  15,  2016.  Contemporaneously  with  the  execution  of  the  Loan  Agreement,  we
entered into a Securities Purchase Agreement with CRG (the “Securities Purchase Agreement”), pursuant to which CRG purchased 3 shares of our common
stock on September 22, 2015 at a price of $1,678,920 per share, which represents the 10-day average of closing prices of our common stock ending on
September 21, 2015. Pursuant to the Securities Purchase Agreement, we filed a registration statement covering the resale of the shares sold to CRG and
must comply with certain affirmative covenants during the time that such registration statement remains in effect.

On February 14, 2018, we entered into a Series A preferred stock Purchase Agreement (the “Series A Purchase Agreement”) with CRG, pursuant
to  which  it  agreed  to  convert  $38.0  million  of  the  outstanding  principal  amount  of  its  senior  secured  term  loan  (plus  the  back-end  fee  and  prepayment
premium applicable thereto) under the Loan Agreement into a newly authorized Series A preferred stock. As discussed in the section of this report titled
“Dividend Policy,” the holders of Series A preferred stock are entitled to receive annual accruing dividends at a rate of 8%, payable in additional shares of
Series A preferred stock or cash, at our option. The shares of Series A preferred stock have no voting rights and rank senior to all other classes and series of
the Company’s equity in terms of repayment and certain other rights with the exception of Series E preferred stock. In March 2024, all outstanding shares
of Series A preferred stock were cancelled in exchange for the issuance of Series A-1 preferred stock. The Series A-1 preferred stock, which is immediately
convertible, carries no liquidation preference or dividend rights.

We  have  entered  into  several  amendments  (collectively,  the  “Amendments”)  to  the  Loan  Agreement  with  CRG  since  September  2015.  The
Amendments, among other things: (1) extended the interest-only period through December 31, 2026; (2) extended the period during which we may elect to
pay  a  portion  of  interest  in  payment-in-kind  (“PIK”),  interest  payments  through  December  31,  2026  so  long  as  no  Default  (as  defined  in  the  Loan
Agreement) has occurred and is continuing; (3) permitted us to make our entire interest payments in PIK interest payments through December 31, 2026 so
long  as  no  Default  has  occurred  and  is  continuing;  (4)  extended  the  Stated  Maturity  Date  (as  defined  in  the  Loan  Agreement)  to  December  31,  2028;
(5) reduced the minimum liquidity covenant to $3.5 million at all times; (6) eliminated the minimum revenue covenant for all years; (7) changed the date
under  the  on-going  stand-alone  representation  regarding  no  “Material  Adverse  Change”  to  December  31,  2020;  (8)  amended  the  on-going  stand-alone
representation and stand-alone Event of Default (as defined in the Loan Agreement) regarding Material Adverse Change such that any adverse change in or
effect upon the revenue of us and our subsidiaries due to the outbreak of COVID-19 will not constitute a Material Adverse Change; (9) provided CRG with
board observer rights, and (10) provide that the board observer may be appointed or removed by written notice from the Majority Lenders (as defined in the
Loan Agreement).

On August 2, 2023, we entered into a Series E preferred stock Purchase Agreement (the “Series E Purchase Agreement”) with CRG, pursuant to
which we issued 1,920 shares of a newly authorized Series E convertible preferred stock (“Series E preferred stock”) in exchange for CRG surrendering for
cancellation $1.92 million of outstanding principal and accrued interest of the senior secured term loan. Each share of Series E preferred stock has a stated
value of $1,000 per share and is convertible into 93 shares of our common stock at a conversion price of $10.725 per share. The Series E preferred stock is
initially convertible into 178,560 shares of common stock subject to certain limitations contained in the Series E Purchase Agreement. Under the terms of
the  Series  E  Purchase  Agreement,  the  holders  of  Series  E  preferred  stock  are  entitled  to  receive  annual  accruing  dividends  at  a  rate  of  8%,  payable  in
additional shares of Series E preferred stock or cash, at our option. The shares of Series E preferred stock have full voting rights, on an as-converted basis,
subject to certain limitations. The Series E preferred stock rank senior to all other classes and series of the Company’s equity in terms of repayment and
certain other rights.

On September 29, 2023, the Company entered into the Waiver Agreement with CRG, who hold all of the outstanding shares of the Company’s
Series A and Series E preferred stock. Pursuant to the Waiver Agreement, CRG waived their rights to receive the Series A and Series E preferred dividends
for the year ending December 31, 2023. Such waived preferred dividends were not cumulative or accrued.

On January 26, 2024, we entered into Amendment No. 7 to the Loan Agreement with CRG, which reduces the minimum liquidity requirement of
the Loan Agreement from $3.5 million to $1.0 million until April 1, 2024. Thereafter, we will be subject to the minimum liquidity requirement of $3.5
million.

As part of our Strategic Collaboration, we entered into Amendment No. 9 to the Loan Agreement with CRG, which amends the Loan Agreement
to, among other things: (i) extend the interest-only period through December 31, 2026; (ii) provide that interest payable through December 31, 2026 may be
payable in kind rather than in cash; and (iii) permit the payment of dividends on the preferred stock issued or issuable to the Purchaser. In addition, we
completed the Private Placement for gross proceeds, before expenses, of $7.5 million.

Components of our Results of Operations

Revenues

All of our revenues are currently derived from sales of our various PAD catheters in the United States and select international markets, Lightbox
consoles,  and  related  services.  We  expect  our  revenues  to  increase  in  2024  due  to  the  introduction  of  our  Tigereye  ST  and  Pantheris  LV  products,
investments in sales personnel and easing conditions involving hospital staffing and capacity issues. For the years ended December 31, 2023 and 2022,
there was one customer that represented approximately 17% and 14% of revenues, respectively.

Revenues  may  fluctuate  from  quarter  to  quarter  due  to  a  variety  of  factors  including  capital  equipment  purchasing  patterns  that  are  typically
increased towards the end of the calendar year and decreased in the first quarter and our ability to have product available in light of supply chain challenges.
In addition, during the first quarter, our results can be harmed by adverse weather and by resetting of annual patient healthcare insurance plan deductibles,
both of which may cause patients to delay elective procedures. In the third quarter, the number of elective procedures nationwide is historically lower than
other quarters throughout the year, which we believe is primarily attributable to the summer vacations of physicians and their patients. Additionally, we
believe hospital capacity and staffing issues have had and will continue to have an adverse effect on our ability to generate sales due to the fluctuating and
unpredictable levels of capacity medical providers have to perform procedures that require the use of our products.

Cost of Revenues and Gross Margin

Cost  of  revenues  consists  primarily  of  costs  related  to  manufacturing  overhead,  materials  and  direct  labor.  We  expense  all  warranty  costs  and
inventory  provisions  as  cost  of  revenues.  We  periodically  write-down  inventory  for  estimated  excess,  obsolete  and  non-sellable  inventories  based  on
assumptions  about  future  demand,  past  usage,  changes  to  manufacturing  processes  and  overall  market  conditions.  A  significant  portion  of  our  cost  of
revenues currently consists of manufacturing overhead costs. These overhead costs include the cost of quality assurance, material procurement, inventory
control, facilities, equipment and operations supervision and management. We expect overhead costs as a percentage of revenues to become less significant
as our production volume increases. Cost of revenues also includes depreciation expense for production equipment, depreciation and related maintenance
expense for placed Lightboxes held by customers and certain direct costs such as those incurred for shipping our products.

We calculate gross margin as gross profit divided by revenues. Our gross margin has been and will continue to be affected by a variety of factors,
primarily production volumes, manufacturing costs, product yields, headcount, charges for excess and obsolete inventories and cost-reduction strategies.
We  intend  to  use  our  design,  engineering  and  manufacturing  capabilities  to  further  advance  and  improve  the  efficiency  of  our  manufacturing  processes,
which we believe will reduce costs and increase our gross margin. In the future, we may seek to manufacture certain of our products outside the United
States to further reduce costs. Our gross margin will likely fluctuate from quarter to quarter as we continue to introduce new products and sales channels,
and as we adopt new manufacturing processes and technologies.

Research and Development Expenses

Research and development (“R&D”), expenses consist primarily of engineering, product development, clinical and regulatory affairs, consulting
services,  materials,  depreciation  and  other  costs  associated  with  products  and  technologies  in  development.  These  expenses  include  employee
compensation, including stock-based compensation, supplies, materials, quality assurance expenses allocated to R&D programs, consulting, related travel
expenses and facilities expenses. Clinical expenses include clinical trial design, clinical site reimbursement, data management, travel expenses and the cost
of  manufacturing  products  for  clinical  trials.  We  expect  R&D  expenses  to  vary  over  time  depending  on  the  level  and  timing  of  our  new  product
development efforts, as well as our clinical development, clinical trial and other related activities.

Selling, General and Administrative Expenses

Selling,  general  and  administrative  (“SG&A”),  expenses  consist  primarily  of  compensation  for  personnel,  including  stock-based  compensation,
selling  and  marketing  functions,  physician  education  programs,  business  development,  finance,  information  technology  and  human  resource  functions.
Other SG&A expenses include commissions, training, travel expenses, educational and promotional activities, marketing initiatives, market research and
analysis, conferences and trade shows, professional services fees, including legal, audit and tax fees, insurance costs and general corporate expenses. We
expect SG&A expenses to increase as we expand our commercial efforts and additional costs related to corporate matters.

Interest Expense, Net

Interest expense, net consists primarily of interest incurred on our outstanding indebtedness and non-cash interest related to the amortization of

debt discount and issuance costs associated with our debt agreement.

Other Income (Expense), Net

Other income (expense), net primarily consists of gains and losses resulting from the remeasurement of foreign exchange transactions and other

miscellaneous income and expenses.

Revenues decreased $0.6 million, or 8%, to $7.7 million during the year ended December 31, 2023. Our revenues reflect the fluctuating demand
partially due to the adverse impacts of hospital staffing shortages as capacity limitations in hospitals have limited the ability of practitioners to perform
elective surgical procedures using our products in certain jurisdictions. In addition, we have experienced and expect that we will continue to experience
attrition and turnover of our sales professionals which has resulted in a less experienced sales team and limited our ability to maintain an adequate presence
in some markets. The attrition and turnover are largely attributable to the increasingly competitive labor market landscape, which has had an adverse effect
on our ability to generate revenues for the year ended December 31, 2023.

Revenues  decreased  $1.9  million,  or  18%,  to  $8.3  million  during  the  year  ended  December  31,  2022.  The  decrease  in  revenues  reflects  the

ability of practitioners to perform elective surgical procedures using our products in certain jurisdictions. In addition, we have experienced attrition and

ability to generate revenues for the year ended December 31, 2022.

Cost of Revenues and Gross Margin.

Cost of revenues increased less than $0.1 million, or 1%, to $5.6 million during the year ended December 31, 2023. This increase was primarily
attributable fluctuations in labor costs and inventory production, increased material costs and other ancillary expenditures, partially offset by the decline in
revenues.  Stock-based  compensation  expense  within  cost  of  revenues  totaled  $134,000  and  $18,000  for  the  years  ended  December  31,  2023  and  2022,
respectively.

Gross  margin  for  the  year  ended  December  31,  2023  decreased  to  26%  compared  to  32%  in  the  prior  year.  There  are  significant  amounts  of
overhead  costs,  specifically  in  the  form  of  labor,  associated  with  manufacturing  and  production  of  inventory  embedded  in  cost  of  revenues  that  will
typically fluctuate due to the levels of inventory being produced, production schedule changes, lead times and other factors. The decrease in gross margin
was primarily due to the decrease in revenues which resulted in a decline in economies of scale.

Research and Development Expenses.

R&D  expenses  increased  $0.2  million  or  3%,  to  $4.5  million  during  the  year  ended  December  31,  2023.  The  increase  is  primarily  due  to  the
ongoing product development of our coronary device program, partially offset by the completion of our development efforts of Tigereye ST and Pantheris
LV.  Stock-based  compensation  expense  within  R&D  totaled  $200,000  and  $37,000  for  the  years  ended  December  31,  2023  and  2022,  respectively.  We
expect R&D expense to fluctuate based on the ongoing product development of our coronary device.

Selling, General and Administrative Expenses.

SG&A  expenses  decreased  $0.1  million,  or  1%,  to  $14.1  million  during  the  year  ended  December  31,  2023.  This  decrease  was  primarily
attributable to decreases in sales personnel costs resulting from the decline in revenues, decreases in third-party professional services and other ancillary
expenses, which were partially offset by increases in certain variable compensation. Stock-based compensation expense within SG&A totaled $606,000 and
$72,000 for the years ended December 31, 2023 and 2022, respectively. We expect SG&A expense to increase during 2024 largely due to investments made
to increase the number of sales personnel deployed within the United States and increases in variable compensation related to fluctuations in revenues.

Interest Expense, Net.

Interest  expense,  net  is  comprised  of  interest  expense  net  of  interest  income.  Interest  expense  remained  flat  compared  to  the  prior  year  which
resulted from increases in interest income due to the recent rising money market interest rates, offset by the higher CRG loan balance from PIK interest
being compounded.

Other Income (Expense), Net.

Other income (expense), net primarily consists of gains and losses resulting from the remeasurement of foreign exchange transactions, which are
typically a small percentage of transaction volume, and other miscellaneous income and expenses. Other income, net for the year ended December 31, 2023
remained relatively flat in comparison to the year ended December 31, 2022 as both periods consisted primarily of remeasurement gains and losses from
foreign exchange transactions, resulting in nominal changes between periods.

Liquidity and Capital Resources

As of December 31, 2023, we had cash and cash equivalents of $5.3 million and an accumulated deficit of $420.7 million, compared to cash and
cash equivalents of $14.6 million and an accumulated deficit of $402.4 million as of December 31, 2022. On March 5, 2024, we entered into a financing as
part  of  a  broader  strategic  collaboration  with  Zylox-Tonbridge  in  which  we  received  an  aggregate  of  $7.5  million  before  any  commissions,  legal  and
accounting fees, and other ancillary expenses. We expect to incur losses for the foreseeable future. We believe that our cash and cash equivalents of $5.3
million at December 31, 2023, together with proceeds from the aforementioned March 2024 financing, and expected revenues, debt and financing activities
and funds from operations will be sufficient to allow us to fund our current operations through at least the second quarter of 2024.

Table of Contents

To  date,  we  have  financed  our  operations  primarily  through  net  proceeds  from  the  issuance  of  our  preferred  stock,  common  stock  and  debt
financings, our at the market program, our initial public offering (“IPO”), our follow-on public offerings and warrant issuances. We do not know when or if
our operations will generate sufficient cash to fund our ongoing operations. We will need to raise additional capital through future equity or debt financings
in  the  near  future  to  meet  our  operational  needs  and  capital  requirements  for  product  development,  clinical  trials  and  commercialization,  and  to  regain
compliance  with  the  Equity  Requirement  of  the  Nasdaq  Listing  Rules.  Additional  debt  financing,  if  available,  may  involve  covenants  restricting  our
operations or our ability to incur additional debt. Any additional debt financing or additional equity that we raise may contain terms that are not favorable to
us or our stockholders and require significant debt service payments, which divert resources from other activities. Additional financing may not be available
at all, or if available, may not be in amounts or on terms acceptable to us. If we are unable to obtain additional financing, we may be required to delay the
development,  commercialization  and  marketing  of  our  products  and  we  may  be  required  to  significantly  scale  back  our  business  and  operations.  In  the
event we determine that additional sources of liquidity will not be available to us or will not allow us to meet our obligations as they become due, we may
need to file a voluntary petition for relief under the United States Bankruptcy Code in order to implement a restructuring plan or liquidation. Our financial
statements for the year ended December 31, 2023 do not include any adjustments that might result from the outcome of this uncertainty.

Currently substantially all of our cash and cash equivalents are held at a single financial institution, First Citizens Bank, which acquired our prior
banking partner, Silicon Valley Bank, in March 2023. On March 10, 2023, the Federal Deposit Insurance Corporation announced that Silicon Valley Bank,
now  a  division  of  First  Citizens  Bank,  had  been  closed  by  the  California  Department  of  Financial  Protection  and  Innovation.  While  we  have  regained
access to our accounts at First Citizens Bank, formerly, Silicon Valley Bank, we are evaluating our banking relationships, future disruptions of financial
institutions where we bank or have credit arrangements, or disruptions of the financial services industry in general, that could adversely affect our ability to
access our cash and cash equivalents. If we are unable to access our cash and cash equivalents as needed, our financial position and ability to operate our
business will be adversely affected.

January 2022 Offering

On January 14, 2022, we entered into a securities purchase agreement with several institutional investors pursuant to which we agreed to sell and
issue,  in  a  registered  direct  offering  (“January  2022  Offering”),  an  aggregate  of  7,600  shares  of  our  Series  D  Convertible  Preferred  Stock,  par  value  of
$0.001  per  share,  at  an  offering  price  of  $1,000  per  share  which  was  convertible  into  common  stock  at  a  conversion  price  of  $120.00  per  share.
Concurrently,  we  agreed  to  issue  to  these  investors  warrants  to  purchase  up  to  an  aggregate  of  53,833  shares  of  our  common  stock  (the  “Common
Warrants”). As a result, we received aggregate net proceeds of approximately $6.7 million after underwriting discounts, commissions, legal and accounting
fees, and other ancillary expenses. During the year ended December 31, 2022, all 7,600 shares issued of Series D preferred stock were converted into a total
of 63,333 shares of common stock. Consequently, there were no shares of Series D preferred stock outstanding as of December 31, 2022.

The  53,833  Common  Warrants  have  an  exercise  price  of  $144.00  per  share  and  became  exercisable  beginning  July  14,  2022.  The  Common
Warrants  will  expire  five  years  following  the  time  they  become  exercisable,  or  July  14,  2027.  We  also  issued  to  the  Placement  Agent  or  its  designees
warrants to purchase up to an aggregate of 4,433 shares of common stock (the “Placement Agent Warrants”). The Placement Agent Warrants are subject to
the same terms as the Common Warrants, except that the Placement Agent Warrants have an exercise price of $150.00 per share and a term of five years
from the commencement of the sales pursuant to the January 2022 Offering, or January 12, 2027.

At The Market Offering Agreement

On  May  20,  2022,  we  entered  into  an  At  The  Market  Offering  Agreement  (the  “ATM  Agreement”)  with  H.C.  Wainwright  &  Co.,  LLC  (the
“Agent”), as sales agent, pursuant to which we may offer and sell shares of common stock, par value $0.001 per share (the “Shares”) up to an aggregate
offering price of $7,000,000 from time to time, in an at the market public offering. Sales of the Shares are to be made at prevailing market prices at the time
of sale, or as otherwise agreed with the Agent. The Agent will receive a commission from us of 3.0% of the gross proceeds of any Shares sold under the
ATM Agreement. The Shares sold under the ATM Agreement are offered and sold pursuant to our shelf registration statement on Form S-3, which was
initially filed with the SEC on March 29, 2022 and declared effective on April 7, 2022, and a prospectus supplement and the accompanying prospectus
relating to the At The Market Offering filed with the SEC on May 20, 2022. During the year ended December 31, 2022, we sold 39,048 shares of common
stock pursuant to the ATM Agreement at an average price of $25.08 per share for aggregate proceeds of $1.0 million, of which approximately $29,000 was
paid in the form of commissions to the Agent. On August 3, 2022, we suspended sales under the ATM Agreement. On March 17, 2023, we reactivated the
ATM Agreement. During the year ended December 31, 2023, we sold 607,241 shares of common stock at an average price of $9.01 per share for aggregate
proceeds of approximately $5.5 million, of which approximately $0.2 million was paid in the form of commissions to the Agent. While we may attempt
additional sales in the future, there can be no assurance that we will be successful in acquiring additional funding through these means.

Other than the ATM Agreement, we currently do not have any commitment to obtain additional funds.

August 2022 Offering

On August 4, 2022, we entered into a securities purchase agreement with a single institutional investor for the issuance and sale of 98,935 shares
of its common stock in a registered direct offering (“RD” or “Registered Direct”) at a purchase price of $26.28 per share, or pre-funded warrants in lieu
thereof. In a concurrent private placement, we also agreed to issue and sell to the investor 91,324 shares of common stock at the same purchase price as in
the registered direct offering, or pre-funded warrants in lieu thereof (“Private Placement” and together with the Registered Direct offering the “August 2022
Offering”). As a result, we received aggregate net proceeds of approximately $4.4 million after underwriting discounts, commissions, legal and accounting
fees, and other ancillary expenses.

As a result, in the Registered Direct offering, we issued (i) 46,667 shares of common stock, (ii) and pre-funded warrants in lieu of common stock
to purchase up to an aggregate of 52,268 shares of common stock (the “RD Pre-Funded Warrants”) and in the Private Placement, we issued pre-funded
warrants to purchase up to an aggregate of 91,324 shares of common stock (the “Private Placement Pre-Funded Warrants” and together with the RD Pre-
Funded  Warrants  the  “August  2022  Pre-Funded  Warrants”).  As  of  December  31,  2023,  all  the  Private  Placement  Pre-Funded  Warrants  were  exercised
leaving none outstanding.

In addition, we issued to the investor in the August 2022 Offering Series A preferred investment options to purchase up to 190,259 additional
shares of our common stock and Series B preferred investment options to purchase up to 190,259 additional shares of our common stock (the “Preferred
Investment Options”). The Series A preferred investment options have an exercise price of $22.53 per share, are immediately exercisable, and will expire
five and one-half years from the date of issuance, or February 8, 2028, and the Series B preferred investment options have an exercise price of $22.53 per
share, are immediately exercisable, and will expire two years from the date of issuance, or August 8, 2024. We also issued to the Placement Agent or its
designees  preferred  investment  options  to  purchase  up  to  an  aggregate  of  11,416  shares  of  common  stock  (the  “Placement  Agent  Preferred  Investment
Options”). The Placement Agent Preferred Investment Options are subject to the same terms as the Preferred Investment Options, except that the Placement
Agent Preferred Investment Options have an exercise price of $32.85 per share and a term of five years from the commencement of the sales pursuant to
the August 2022 Offering, or August 3, 2027.

March 2024 Financing

In  connection  with  our  the  Strategic  Collaboration,  we  entered  into  a  Securities  Purchase  Agreement  (the  “Purchase  Agreement”)  with  Zylox-
Tonbridge Medical Limited, a wholly-owned subsidiary of Zylox-Tonbridge (the “Purchaser”), pursuant to which the Purchaser agreed to purchase, in two
tranches, up to an aggregate of $15 million in shares of our common stock, par value $0.001 per share (the “Common Stock”), and shares of two new series
of our preferred stock (the “Private Placement”). On March 5, 2024, (the “Initial Closing”), we issued to the Purchaser 75,327 shares of the Common Stock
at  a  purchase  price  per  share  of  $3.664  (the  “Purchase  Price”),  and  7,224  shares  of  a  newly  authorized  Series  F  convertible  preferred  stock,  par  value
$0.001 per share (the “Series F Preferred Stock”), for an aggregate purchase price of $7.5 million. Each share of Series F Preferred Stock has a stated value
of $1,000 and is initially convertible into approximately 273 shares of Common Stock at a conversion price equal to the Purchase Price, subject to the terms
of the Certificate of Designation of Preferences, Rights, and Limitations of the Series F Preferred Stock (the “Series F Certificate of Designation”).

Upon completion of the following as mutually agreed upon us and the Purchaser: (i) the successful registration and listing under 21 CFR part 807
with the FDA of the Purchaser and one of its designated affiliates to manufacture our products, and (ii) our achieving an aggregate of $10 million in gross
revenue  within  any  four  consecutive  fiscal  quarters  after  the  Initial  Closing,  excluding  any  gross  revenue  related  to  sales  of  our  products  to  Zylox-
Tonbridge (together, the “Milestones”), the Purchaser will invest an additional $7.5 million (the “Milestone Closing”) to purchase shares our new Series G
convertible preferred stock, par value $0.001 per share (the “Series G Preferred Stock”). Each share of Series G Preferred Stock will have a stated value of
$1,000 and will be convertible into shares of Common Stock at a conversion price of equal to the lowest of (x) the Purchase Price, (y) the closing price of
the  Common  Stock  on  the  date  immediately  preceding  the  Milestone  Closing,  and  (z)  the  average  of  the  closing  price  for  the  last  five  trading  days
preceding the Milestone Closing, provided that the conversion price will be no less than $0.20. There can be no guarantee that such Milestone Closing will
occur.

(1) Operating lease obligations primarily consist of leased office, laboratory, and manufacturing space under a non-cancelable operating lease. In addition
to the minimum future lease commitments presented above, the lease requires the Company to pay property taxes, insurance, maintenance, and repair
costs. As of December 31, 2023, the lease was to expire on November 30, 2024. On March 6, 2024, we entered into an amendment to the lease which
extended the lease term for a period of one year, subsequent to the original expiration of November 30, 2024. As amended, the lease will expire on
November  30,  2025.  Under  the  terms  of  the  amendment,  we  will  be  obligated  to  pay  approximately  $1.3  million  in  base  rent  payments  through
November  2025,  beginning  on  December  1,  2024.  These  base  payments  resulting  from  the  lease  extension  are  not  reflected  in  the  contractual
obligations within the table above.

(2) The total CRG Loan amount, shown as borrowings on the balance sheet as of December 31, 2023, is $14.3 million. The contractual obligation in the
table above of $16.9 million under the CRG Loan includes future interest to be accrued but not paid in cash as well as a $2.1 million back-end fee to be
paid in December 2025 upon maturity of the CRG Loan which is being accreted. Refer to Item 8, Financial Statements and Supplementary Data, Note
7 for additional details. On March 4, 2024, we entered into Amendment No. 9 to the Loan Agreement with CRG, which amends the Loan Agreement
to,  among  other  things:  (i)  extend  the  interest-only  period  through  December  31,  2026  and  (ii)  provide  that  interest  payable  through  December  31,
2026 may be payable in kind rather than in cash. The changes resulting from this amendment are not reflected in the contractual obligations within the
table above.

(3) Noncancelable purchase commitments consist of agreements to purchase goods and services entered into in the ordinary course of business.

CRG Loan

We  have  entered  into  several  amendments  to  the  Loan  Agreement  (the  “Amendments”)  with  CRG  since  September  2015.  The  Amendments,
among other things: (1) extended the interest-only period through December 31, 2026; (2) extended the period during which we may elect to pay a portion
of  interest  in  payment-in-kind,  or  PIK,  interest  payments  through  December  31,  2026  so  long  as  no  Default  (as  defined  in  the  Loan  Agreement)  has
occurred and is continuing; (3) permitted us to make the entire interest payments in PIK interest payments for through December 31, 2026 so long as no
Default has occurred and is continuing; (4) extended the Stated Maturity Date (as defined in the Loan Agreement) to December 31, 2028; (5) reduced the
minimum liquidity covenant to $3.5 million at all times; (6) eliminated the minimum revenue covenant for all years; (7) changed the date under the on-
going stand-alone representation regarding no “Material Adverse Change” to December 31, 2020; (8) amended the on-going stand-alone representation and
stand-alone Event of Default (as defined in the Loan Agreement) regarding Material Adverse Change such that any adverse change in or effect upon the
revenue of us and our subsidiaries due to the outbreak of COVID-19 will not constitute a Material Adverse Change; (9) provided CRG with board observer
rights,  and  (10)  provide  that  the  board  observer  may  be  appointed  or  removed  by  written  notice  from  the  Majority  Lenders  (as  defined  in  the  Loan
Agreement). The total Loan amount under the Loan Agreement (the “CRG Loan”), shown as short-term borrowings on the balance sheet as of December
31, 2023, is $14.3 million. However, upon maturity of the obligations under the Loan Agreement in December 2025, we will be obligated to pay $16.9
million under the Loan Agreement, which includes future interest to be accrued but not paid in cash as well as a $2.1 million back-end fee to be paid in
December 2025 upon maturity of the CRG Loan which is being accreted to the maturity date. Due to the substantial doubt about our ability to continue
operating  as  a  going  concern  and  the  “Material  Adverse  Change”  clause  under  the  Loan  Agreement,  the  entire  amount  of  outstanding  borrowings  at
December 31, 2023 and 2022 is classified as current. CRG has not purported that any Event of Default (as defined in the Loan Agreement) has occurred as
a result a “Material Adverse Change” under the Loan Agreement. Refer to Item 8, Financial Statements and Supplementary Data, Note 7 for additional
details.

On August 2, 2023, we entered into a Series E preferred stock Purchase Agreement (the “Series E Purchase Agreement”) with CRG, pursuant to
which we issued 1,920 shares of a newly authorized Series E convertible preferred stock (“Series E preferred stock”) in exchange for CRG surrendering for
cancellation $1.92 million of outstanding principal and accrued interest of the senior secured term loan. Each share of Series E preferred stock has a stated
value of $1,000 per share and is convertible into 93 shares of our common stock at a conversion price of $10.725 per share. The Series E preferred stock is
initially convertible into 178,560 shares of common stock subject to certain limitations contained in the Series E Purchase Agreement. Under the terms of
the  Series  E  Purchase  Agreement,  the  holders  of  Series  E  preferred  stock  are  entitled  to  receive  annual  accruing  dividends  at  a  rate  of  8%,  payable  in
additional shares of Series E preferred stock or cash, at our option. The shares of Series E preferred stock have full voting rights, on an as-converted basis,
subject to certain limitations. The Series E preferred stock rank senior to all other classes and series of the Company’s equity in terms of repayment and
certain other rights.

On January 26, 2024, we entered into Amendment No. 7 to the Loan Agreement with CRG, which reduces the minimum liquidity requirement of
the Loan Agreement from $3.5 million to $1.0 million until April 1, 2024. Thereafter, we will be subject to the minimum liquidity requirement of $3.5
million.

As part of our Strategic Collaboration, we entered into Amendment No. 9 to the Loan Agreement with CRG, which amends the Loan Agreement
to, among other things: (i) extend the interest-only period through December 31, 2026; (ii) provide that interest payable through December 31, 2026 may be
payable in kind rather than in cash; and (iii) permit the payment of dividends on the preferred stock issued or issuable to the Purchaser.

Lease Agreements

Our operating lease obligations primarily consist of leased office, laboratory, and manufacturing space under a non-cancelable operating lease. In
addition to the minimum future lease commitments presented below, the lease requires us to pay property taxes, insurance, maintenance, and repair costs.
The lease includes a rent holiday concession and escalation clauses for increased rent over the lease term. Rent expense is recognized using the straight-line
method over the term of the lease.

The lease will expire on November 30, 2024. We are obligated to pay a total approximately $5.8 million in base rent payments through November

2024, which began on December 1, 2019. The weighted average remaining lease term as of December 31, 2023 is 0.9 years.

On March 6, 2024, we entered into an amendment to the lease which extended the lease term for a period of one year, subsequent to the original
expiration of November 30, 2024. As amended, the lease will expire on November 30, 2025. Under the terms of the amendment, we will be obligated to
pay approximately $1.3 million in base rent payments through November 2025, beginning on December 1, 2024. This amendment also provides an optional
one year extension of the lease following the end of the current term, as amended.

Net cash used in operating activities for the year ended December 31, 2023 was $14.4 million, consisting primarily of a net loss of $18.3 million,
partially offset by non-cash charges of $3.7 million and a decrease in net operating assets of $0.2 million. Non-cash charges largely related to non-cash
interest  expense  of  $2.0  million,  excess  and  obsolete  charges  related  to  inventory  of  $0.4  million,  depreciation  of  $0.3  million  and  stock-based
compensation of $0.9 million. The decrease in net operating assets was primarily due an increase in accrued compensation as certain variable compensation
continued to accrue, a large portion of which was reclassified from other long-term liabilities as it became due within less than one year. Other decreases in
net operating assets resulted from an increase in accounts payable and accrued expenses and other current liabilities due to timing of payments and timing
of the incurrence of expenditures. This was largely offset by investments in inventory, which include components and labor, in anticipation of (i) forecasted
demand in light of extended lead times and (ii) building inventory in anticipation of the commercial needs following the product launch of Tigereye ST in
the second half of 2023 and the anticipated full commercial launch of Pantheris LV around mid-year 2024.

Net cash used in operating activities for the year ended December 31, 2022 was $16.8 million, consisting primarily of a net loss of $17.6 million
and an increase in net operating assets of $1.7 million, partially offset by non-cash charges of $2.6 million. Non-cash charges largely related to non-cash
interest expense of $1.9 million. The increase in net operating assets was primarily due to the increase in inventory of $1.4 million due to purchases of
inventory components in anticipation of forecasted demand in light of extended lead times and a decrease in accounts payable due to timing of payments
and overall, less expenditures. These increases were partially offset by the increase in other long-term liabilities as certain variable compensation continues
to accrue.

Net Cash Used in Investing Activities

Net cash used in investing activities during both the years ended December 31, 2023 and 2022 consisted of purchases of property and equipment.

Net Cash Provided by Financing Activities

Net cash provided by financing activities for the year ended December 31, 2023 of $5.1 million relates to proceeds of approximately $5.1 million

from the sale of common stock pursuant to the ATM Agreement, net of commissions and various issuance costs.

Net cash provided by financing activities for the year ended December 31, 2022 of $11.9 million primarily relates to proceeds of $6.7 million from
the issuance of preferred stock and warrants in the January 2022 Offering, net of commissions and various issuance costs, and proceeds of $4.4 million
from the issuance of common stock and preferred investment options in the August 2022 Offering. We also received approximately $0.8 million, net of
commissions and various issuance costs, from the sale of common stock pursuant to the ATM Agreement.

Critical Accounting Policies and Estimates

Management’s discussion and analysis of our financial condition and results of operations is based on our financial statements, which have been
prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and
assumptions for the reported amounts of assets, liabilities, revenues, expenses and related disclosures of contingent assets and liabilities. Our estimates are
based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis
for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these
estimates under different assumptions or conditions and any such differences may be material.

While  our  significant  accounting  policies  are  more  fully  described  in  Note  2  of  our  financial  statements  included  in  this  Annual  Report  on
Form 10-K, we believe the following discussion addresses our most critical accounting policies, which are those that are most important to our financial
condition and results of operations and require our most difficult, subjective and complex judgments.

Revenue Recognition

The Company’s revenues are derived from (1) sale of Lightbox consoles, (2) sale of disposables, which consist of catheters and accessories, and
(3)  sale  of  customer  service  contracts  and  maintenance.  The  Company  sells  its  products  directly  to  hospitals  and  medical  centers  as  well  as  through
distributors. The Company accounts for a contract with a customer when there is a legally enforceable contract between the Company and the customer, the
rights  of  the  parties  are  identified,  the  contract  has  commercial  substance,  and  collectability  of  the  contract  consideration  is  probable.  The  Company’s
revenues are measured based on consideration specified in the contract with each customer, net of any sales incentives and taxes collected from customers
that  are  remitted  to  government  authorities.  For  all  sales,  the  Company  uses  either  a  signed  agreement,  a  binding  purchase  order  or  other  written
documentation as evidence of an arrangement. The Company’s revenue recognition policies generally result in revenue recognition at the following points:

1.

2.

3.

Lightbox console sales: Provided all other criteria for revenue recognition have been met, the Company recognizes revenue for Lightbox
console sales directly to end customers when delivery and acceptance occurs, which is defined as receipt by the Company of an executed
form that the installation process is complete. If installation is not required, as is the case with the Lightbox 3, recognition occurs upon
the completion of delivery pursuant to the stated delivery terms.

Sales  of  disposables:  Disposable  revenues  consist  of  sales  of  the  Company’s  catheters  and  accessories  and  are  recognized  when  the
product has shipped, risk of loss and title has passed to the customer and collectability is reasonably assured.

Service  revenue:  Service  contract  revenue  consists  of  preventative  maintenance,  upgrades,  and  service  contracts.  Service  contracts  are
recognized ratably over the term of the service period and maintenance contract revenue is recognized when work is completed. To date,
service revenue has been insignificant.

Table of Contents

The Company offers its customers the ability to purchase or lease the Lightbox console. In addition, the Company provides a Lightbox under a
limited commercial evaluation program to allow accounts to install and utilize the Lightbox for a limited trial period. When a Lightbox is placed under a
lease agreement or under a commercial evaluation program, the Company retains title to the equipment and it remains capitalized on its balance sheet under
property and equipment. Depreciation expense on these placed Lightboxes is recorded to cost of revenues on a straight-line basis. The costs to maintain
these placed Lightboxes are charged to cost of revenues as incurred.

The  Company  evaluates  its  lease  and  commercial  evaluation  program  agreements  and  accounts  for  these  contracts  under  the  guidance  in
Accounting  Standards  Codification  (“ASC”)  842,  Leases  and  ASU  No.  2014  09,  Revenue  from  Contracts  with  Customers  (Topic  606).  The  guidance
requires  arrangement  consideration  to  be  allocated  between  a  lease  deliverable  and  a  non-lease  deliverable  based  upon  the  relative  selling-price  of  the
deliverables.

The Company assessed whether the embedded lease is an operating lease or sales-type lease. Based on the Company’s assessment of the guidance
and given that any payments under the lease agreements are dependent upon contingent future sales, it was determined that collectability of the minimum
lease payments is not reasonably predictable. Accordingly, the Company concluded the embedded lease did not meet the criteria of a sales-type lease and
accounts for it as an operating lease. The Company recognizes revenue allocated to the lease as the contingent disposable product purchases are delivered
and are included in revenues within the statement of operations and comprehensive loss.

For  sales  of  disposables  through  distributors,  the  Company  recognizes  revenue  when  control  of  the  product  transfers  from  the  Company  to  the
distributor. The distributors are responsible for all statutory obligations, marketing, sales, training and warranty in their respective territories. The standard
terms and conditions contained in the Company’s distribution agreements do not provide price protection or stock rotation rights to any of its distributors.
In addition, its distributor agreements do not allow the distributor to return or exchange products, and the distributor is obligated to pay the Company upon
invoice regardless of its ability to resell the product.

Inventories

Inventories are valued at the lower of cost or net realizable value. Cost is determined using the first-in, first-out method for all inventories. The
Company’s policy is to write down inventory that has expired or become obsolete, inventory that has a cost basis in excess of its expected net realizable
value,  and  inventory  in  excess  of  expected  requirements.  At  each  balance  sheet  date,  management  evaluates  inventories  for  excess  quantities,  and
obsolescence.

Critical estimates.  To  the  extent  that  management  determines  there  are  excess  or  obsolete  inventory,  management  adjusts  the  carrying  value  to
estimated  net  realizable  value.  When  quantities  on  hand  exceed  sales  forecasts,  a  write-down  is  recorded  for  such  excess  inventories  along  with  a
corresponding charge to cost of revenues.

Assumptions  and  judgment.  The  estimate  of  excess  quantities  is  subjective  and  primarily  dependent  on  the  estimates  of  future  demand  for  a
particular product. Specifically, the future demand is derived based on our historical experience, from discussion with users of our products and general
market  conditions.  This  evaluation  by  management  includes  analysis  of  historical  sales  levels  by  product,  projections  of  future  demand,  the  risk  of
technological  or  competitive  obsolescence  for  products,  general  market  conditions,  as  well  as  the  feasibility  of  reworking  or  using  excess  or  obsolete
products or components in the production or assembly of other products that are not obsolete or for which there are not excess quantities in inventory.

Impact if actual results differ from assumptions. Changes  in  assumptions  of  product  demand  could  have  a  significant  impact  on  the  amount  of

write-down recorded.

Inventory  used  in  clinical  trials  is  expensed  at  the  time  of  production  and  recorded  as  research  and  development  expense  if  the  inventory  is
contractually being provided at no cost to the clinical site. The cost of inventories are regularly reviewed against estimated market value and record a lower
of cost or market reserve for inventories that have a cost in excess of estimated market value, which could have a material impact on the gross margin and
inventory balances based on additional write-downs to net realizable value or a benefit from inventories previously written down.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

The risk associated with fluctuating interest rates is primarily limited to our cash equivalents, which are carried at quoted market prices. Due to the
short-term maturities and low risk profile of our cash equivalents, an immediate 100 basis point change in interest rates would not have a material effect on
the fair value of our cash equivalents. We do not currently use or plan to use financial derivatives in our investment portfolio.

Credit Risk

As  of  December  31,  2023,  our  cash  and  cash  equivalents  were  maintained  largely  with  one  financial  institution  in  the  United  States,  and  our
current deposits are in excess of insured limits. We have reviewed the financial statements of this institution and believe it has sufficient assets and liquidity
to conduct its operations in the ordinary course of business with little or no credit risk to us.

Our accounts receivable primarily relate to revenues from the sale of our Lumivascular platform products to hospitals and medical centers in the
United States. At December 31, 2023, there was one customer that represented 24% of the Company’s accounts receivable, whereas at December 31, 2022,
there was no customer that represented 10% or more of the Company’s accounts receivable. For the years ended December 31, 2023 and 2022, there was
one customer that represented approximately 17% and 14% of revenues, respectively.

Foreign Currency Risk

Our  business  is  primarily  conducted  in  U.S.  dollars.  Any  transactions  that  may  be  conducted  in  foreign  currencies  are  not  expected  to  have  a

material effect on our results of operations, financial position or cash flows.

herein by reference.

ITEM 9.    CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

None.

ITEM 9A.    CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We  maintain  disclosure  controls  and  procedures  that  are  designed  to  ensure  that  information  required  to  be  disclosed  in  our  reports  under  the
Securities  Exchange  Act  of  1934,  as  amended,  or  the  Exchange  Act,  and  the  rules  and  regulations  thereunder,  is  recorded,  processed,  summarized  and
reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management,
including  our  principal  executive  officer  and  principal  financial  officer,  as  appropriate,  to  allow  for  timely  decisions  regarding  required  disclosure.  In
designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed
and  operated,  can  provide  only  reasonable  assurance  of  achieving  the  desired  control  objectives,  and  management  is  required  to  apply  its  judgment  in
evaluating the cost-benefit relationship of possible controls and procedures.

As  required  by  Rule  13a-15(b)  under  the  Exchange  Act,  our  management,  under  the  supervision  and  with  the  participation  of  our  principal
executive officer and principal financial officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as
such  term  is  defined  in  Rules  13a-15(e)  and  15d-15(e)  under  the  Exchange  Act)  as  of  December  31,  2023.  Based  on  such  evaluation,  our  principal
executive officer and principal financial officer have concluded that, as of December 31, 2023, our disclosure controls and procedures were effective.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rule 13a-15(f) of
the Exchange Act. Our management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in
Internal  Control—Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission.  Based  on  this
evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2023.

This  Annual  Report  on  Form  10-K  does  not  include  an  attestation  report  of  our  registered  public  accounting  firm  on  our  internal  control  over
financial  reporting  We  are  currently  a  non-accelerated  filer  and  are  therefore  not  required  to  provide  an  attestation  report  on  our  internal  control  over
financial reporting until such time as we are an accelerated filer or large accelerated filer.

Changes in Internal Control over Financial Reporting

There were no changes in our internal controls over financial reporting identified in management’s evaluation pursuant to Rules 13a-15(d) and
15d-15(d) of the Exchange Act that occurred during the quarter ended December 31, 2023 that materially affected, or are reasonably likely to materially
affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

Our management, including our chief executive officer and chief financial officer, believes that our disclosure controls and procedures and internal
control  over  financial  reporting  are  designed  to  provide  reasonable  assurance  of  achieving  their  objectives  and  are  effective  at  the  reasonable  assurance
level. However, our management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent all
errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives
of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls
must  be  considered  relative  to  their  costs.  Because  of  the  inherent  limitations  in  all  control  systems,  no  evaluation  of  controls  can  provide  absolute
assurance  that  all  control  issues  and  instances  of  fraud,  if  any,  have  been  detected.  These  inherent  limitations  include  the  realities  that  judgments  in
decision-making  can  be  faulty,  and  that  breakdowns  can  occur  because  of  a  simple  error  or  mistake.  Additionally,  controls  can  be  circumvented  by  the
individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls also is
based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its
stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance
with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may
occur and not be detected.

Elias  was  VP,  Clinical  Product  Development  at  Aetna  from  2018  to  2020.  From  2015  to  2017,  Dr.  Elias  was  Vice  President  of  Corporate  Strategy  and
Business  Development  for  the  $8  billion  medical  segment  at  Becton  Dickinson.  From  2007  to  2015,  Dr.  Elias  was  a  Partner  with  Essex  Woodlands
Healthcare  Partners,  a  healthcare  only  growth  equity  firm  founded  in  1985.  Earlier  in  her  career,  Dr.  Elias  was  a  management  consultant  at  McKinsey,
advising  pharmaceutical,  diagnostic  and  device  companies  in  R&D,  product  commercialization  and  M&A.  She  currently  serves  on  the  board  of  REVA
Medical  BehaVR.  Dr.  Elias  has  previously  served  on  the  boards  of  several  private  companies,  including  Millennium  Pharmacy  Systems  (sold  to

Elias holds degrees in Biology and Anthropology from Yale University, and an M.D. from The Johns Hopkins School of Medicine. She trained as a general

We believe Dr. Elias is qualified to serve as a member of our board of directors because of her substantial corporate development and business

strategy expertise and her experience in the healthcare industry.

associate  director  and  scientist  at  Guilford  Pharmaceuticals,  Inc.  Dr.  Zhao  holds  a  bachelor’s  degree  in  polymer  chemistry  and  synthesis  from  Sichuan
University in the People’s Republic of China and a Ph.D. degree in biomedical engineering from The Johns Hopkins University School of Medicine in the

Code of Business Conduct

We have adopted a code of business conduct that applies to all of our employees, officers and directors, including those officers responsible for
financial reporting. The code of business conduct is available on our website at www. investors.avinger.com/governance. Updates to or waivers of the code
will be disclosed on the same website. We intend to satisfy the disclosure requirement under Item 5.05 of Form 8-K regarding any amendment to, or waiver
of, any provision of the code in the future by disclosing such information on our website.

Board Leadership Structure

We  believe  that  the  structure  of  our  board  of  directors  and  its  committees  provides  strong  overall  management  of  our  company.    Our  board  of
directors  does  not  have  a  formal  policy  on  whether  the  roles  of  Chief  Executive  Officer  and  Chairman  of  our  board  of  directors  should  be  separate. 
However, Messrs. Soinski and Cullen, respectively, hold these positions at present.

Our Chief Executive Officer, Mr. Soinski, is responsible for setting the strategic direction of our company, the general management and operation
of the business and the guidance and oversight of senior management.  In his capacity as Chairman of our board of directors, Mr. Cullen is also responsible
for  the  guidance  and  oversight  of  senior  management,  monitoring  the  content,  quality  and  timeliness  of  information  sent  to  our  board  of  directors,
consultation with our board of directors regarding the oversight of our business affairs, presiding over meetings of our board of directors and performing
such additional duties as our Board may otherwise determine and delegate.  At the end of each board meeting, the independent directors are expected to
meet  in  executive  session,  without  Mr.  Soinski  present.    Following  each  meeting,  Mr.  Cullen  is  expected  to  provide  feedback  to  Mr.  Soinski  on  his
performance and the performance of our employees during the meeting and to recommend new agenda items for the next meeting.

Director Independence

Our common stock is listed on The Nasdaq Capital Market.  Under the Nasdaq listing standards, independent directors must comprise a majority
of a listed company’s board of directors.  In addition, the Nasdaq listing standards require that, subject to specified exceptions, each member of a listed
company’s audit, compensation, and nominating and corporate governance committees be independent.  Under the Nasdaq listing standards, a director will
only qualify as an “independent director” if, in the opinion of that listed company’s board of directors, that director does not have a relationship that would
interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Audit  committee  members  must  also  satisfy  the  additional  independence  criteria  set  forth  in  Rule  10A-3  under  the  Securities  Exchange  Act  of
1934,  as  amended,  or  the  “Exchange  Act,  and  the  Nasdaq  listing  standards.    Compensation  committee  members  must  also  satisfy  the  additional
independence criteria set forth in Rule 10C-1 under the Exchange Act and the Nasdaq listing standards. 

Our board of directors has undertaken a review of the independence of each of our directors.  Based on information provided by each director
concerning his background, employment and affiliations, our board of directors has determined that Messrs. Cullen, McElwee and Dr. Elias do not have a
relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors
is “independent” as that term is defined under the Nasdaq listing standards.  In making these determinations, our board of directors considered the current
and prior relationships that each non-employee director has with our company and all other facts and circumstances our board of directors deemed relevant
in determining their independence, including the beneficial ownership of our capital stock by each non-employee director, and the transactions involving
them described below under the heading “Related Person Transactions.”

Board Meetings and Committees

During our fiscal year ended December 31, 2023, our board of directors held 8 meetings (including regularly scheduled and special meetings), and
each director attended at least 75% of the aggregate of (i) the total number of meetings of our board of directors held during the period for which he or she
has been a director and (ii) the total number of meetings held by all committees of our board of directors on which he or she served during the periods that
he or she served.  All of our directors who were directors at the time attended our 2023 annual meeting of stockholders telephonically.

Although  we  do  not  have  a  formal  policy  regarding  attendance  by  members  of  our  board  of  directors  at  annual  meetings  of  stockholders,  we

strongly encourage our directors to attend.

Our board of directors has established an audit committee, a compensation committee and a nominating and corporate governance committee.  The
composition and responsibilities of each of the committees of our board of directors are described below.  Members will serve on these committees until
their resignation or until as otherwise determined by our board of directors.

Audit Committee

Messrs.  McElwee,  Cullen  and  Dr.  Elias  serve  on  our  audit  committee.    Mr.  Cullen  serves  as  the  chair  of  the  audit  committee.    Our  board  of
directors has assessed whether all members of the audit committee meet the composition requirements of Nasdaq, including the requirements regarding
financial literacy and financial sophistication.  Our board of directors found that Messrs. McElwee, Cullen and Dr. Elias have met the financial literacy and
financial sophistication requirements and that Messrs. McElwee, Cullen and Dr. Elias are independent under SEC and Nasdaq rules.  In addition, our board
of directors has determined that Mr. Cullen is an audit committee financial expert within the meaning of Item 407(d) of Regulation S-K under the Securities
Act of 1933, as amended, or the Securities Act.  The audit committee’s primary responsibilities include:

● appointing,  approving  the  compensation  of,  and  assessing  the  qualifications  and  independence  of  our  independent  registered  public

accounting firm, which currently is Moss Adams LLP;

● reviewing  and  discussing  with  management  and  our  independent  registered  public  accounting  firm  our  annual  and  quarterly  financial

statements and related disclosures;

● preparing the audit committee report required by SEC rules to be included in our annual proxy statements;

● monitoring our internal control over financial reporting, disclosure controls and procedures;

● reviewing our risk management status;

● establishing policies regarding hiring employees from our independent registered public accounting firm and procedures for the receipt and

retention of accounting related complaints and concerns;

● meeting independently with our independent registered public accounting firm and management; and

● monitoring compliance with the code of business conduct and ethics for financial management.

All audit and non-audit services must be approved in advance by the audit committee.  Our audit committee operates under a written charter that
satisfies the applicable rules and regulations of the SEC and Nasdaq listing standards.  A copy of the charter of our audit committee is available on our
website at www.avinger.com under “Investors–Governance.” During our fiscal year ended December 31, 2023, our audit committee held five meetings.

Compensation Committee

Messrs. Cullen, McElwee and Dr. Elias serve on our compensation committee.  Mr. McElwee serves as the chair of the compensation committee. 
Each member of our compensation committee meets the requirements for independence for compensation committee members under the Nasdaq listing
standards  and  SEC  rules  and  regulations,  including  Rule  10C-1  under  the  Exchange  Act.    Each  member  of  our  compensation  committee  is  also  a  non-
employee director, as defined pursuant to Rule 16b-3 promulgated under the Exchange Act, and an outside director, as defined pursuant to Section 162(m)
of the Internal Revenue Code.  Our compensation committee is responsible for, among other things:

● annually  reviewing  and  approving  corporate  goals  and  objectives  relevant  to  compensation  of  our  chief  executive  officer  and  our  other

executive officers;

● determining the compensation of our chief executive officer and our other executive officers;

● reviewing and making recommendations to our board of directors with respect to director compensation; and

● overseeing and administering our equity incentive plans.

Our Chief Executive Officer and Principal Financial Officer make compensation recommendations for our other executive officers and initially
propose the corporate and departmental performance objectives under our Executive Incentive Compensation Plan to the compensation committee.  From
time  to  time,  the  compensation  committee  may  use  outside  compensation  consultants  to  assist  it  in  analyzing  our  compensation  programs  and  in
determining appropriate levels of compensation and benefits.  For example, we have periodically engaged Radford, a business unit of Aon Hewitt, to help
develop our compensation philosophy, select a group of peer companies to use for compensation benchmarking purposes and advise on cash and equity
compensation levels for our directors, executives and other employees based on current market practices.  We did not use any compensation consultants
during our year ended December 31, 2022. Our compensation committee operates under a written charter that satisfies the applicable rules and regulations
of  the  SEC  and  Nasdaq  listing  standards.    A  copy  of  the  charter  of  our  compensation  committee  is  available  on  our  website  at  www.avinger.com under
“Investors–Governance.” During our fiscal year ended December 31, 2023, our compensation committee held four meetings.

Nominating and Corporate Governance Committee

Messrs.  Cullen,  McElwee  and  Dr.  Elias  serve  on  our  nominating  and  corporate  governance  committee.    Dr.  Elias  serves  as  the  chair  of  the
nominating  and  corporate  governance  committee.    Each  member  of  our  nominating  and  corporate  governance  committee  meets  the  requirements  for
independence under the Nasdaq listing standards and SEC rules and regulations.  Our nominating and corporate governance committee is responsible for,
among other things:

● identifying individuals qualified to become members of our board of directors;

● recommending to our board of directors the persons to be nominated for election as directors and to each of our board’s committees;

● reviewing and making recommendations to our board of directors with respect to management succession planning;

● developing, updating and recommending to our board of directors corporate governance principles and policies; and

● overseeing the evaluation of our board of directors and committees.

Our  nominating  and  corporate  governance  committee  operates  under  a  written  charter  that  satisfies  the  applicable  Nasdaq  listing  standards.    A
copy of the charter of our nominating and corporate governance committee is available on our website at www.avinger.com under “Investors–Governance.”
During our fiscal year ended December 31, 2023, our nominating and corporate governance committee held one meeting.

Considerations in Evaluating Director Nominees

Our nominating and corporate governance committee uses a variety of methods for identifying and evaluating director nominees. In its evaluation
of director candidates, our nominating and corporate governance committee will consider the current size and composition of our board of directors and the
needs  of  our  board  of  directors  and  the  respective  committees  of  our  board  of  directors.  Some  of  the  qualifications  that  our  nominating  and  corporate
governance  committee  considers  include,  without  limitation,  issues  of  character,  integrity,  judgment,  diversity  of  experience,  independence,  area  of
expertise, corporate experience, length of service, potential conflicts of interest and other commitments. We also look for nominees who have skills and
experience that would support the short and long-term goals and strategy of the Company. Our nominating and corporate governance committee seeks to
maintain an appropriate balance of backgrounds, skills, knowledge, and experience to support current and future needs. Nominees must also have the ability
to offer advice and guidance to our Chief Executive Officer based on past experience in positions with a high degree of responsibility and be leaders in the
companies or institutions with which they are affiliated.

In  the  case  of  incumbent  directors  whose  terms  of  office  are  set  to  expire,  our  nominating  and  corporate  governance  committee  reviews  these
directors’ overall service to the Company during their terms, including the number of meetings attended, level of participation, quality of performance and
any other relationships and transactions that might impair the directors’ independence.

Director  candidates,  including  incumbent  directors,  must  have  sufficient  time  available  in  the  judgment  of  our  nominating  and  corporate
governance committee to perform all board of director and committee responsibilities. Members of our board of directors are expected to prepare for, attend
and  participate  in  all  board  of  director  and  applicable  committee  meetings.  Other  than  the  foregoing,  there  are  no  stated  minimum  criteria  for  director
nominees, although our nominating and corporate governance committee may also consider such other factors as it may deem, from time to time, are in our
and our stockholders’ best interests.

Although our board of directors does not maintain a specific policy with respect to board diversity, our board of directors believes that our board of
directors should be a diverse body, and our nominating and corporate governance committee considers a broad range of backgrounds and experiences. In
making  determinations  regarding  nominations  of  directors,  our  nominating  and  corporate  governance  committee  may  take  into  account  the  benefits  of
diverse  viewpoints,  backgrounds,  and  experiences.  Our  nominating  and  corporate  governance  committee  also  considers  these  and  other  factors  as  it
oversees the annual board of director and committee evaluations. After completing its review and evaluation of director candidates, our nominating and
corporate governance committee recommends to our full board of directors the director nominees for selection.

In addition to utilizing personal networks and relationships to identify potential candidates, our nominating and corporate governance committee
may also engage, if it deems appropriate, a professional search firm. The nominating and corporate governance committee conducts any appropriate and
necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the board. The nominating
and corporate governance committee meets to discuss and consider the candidates’ qualifications and then selects a nominee for recommendation to the
board.

Stockholder Recommendations for Nominations to the Board of Directors

Our  nominating  and  corporate  governance  committee  will  consider  candidates  for  director  recommended  by  stockholders,  so  long  as  such
recommendations  comply  with  our  amended  and  restated  certificate  of  incorporation,  amended  and  restated  bylaws  and  applicable  laws,  rules  and
regulations,  including  those  promulgated  by  the  SEC.  Our  nominating  and  corporate  governance  committee  will  evaluate  such  recommendations  in
accordance with its charter, our amended and restated bylaws, our policies and procedures for director candidates, as well as the regular director nominee
criteria described above. This process is designed to ensure that our board of directors includes members with diverse backgrounds, skills and experience,
including appropriate financial and other expertise relevant to our business. Eligible stockholders wishing to recommend a candidate for nomination should
contact  our  Secretary  in  writing.  Such  recommendations  must  include  information  about  the  candidate,  a  statement  of  support  by  the  recommending
stockholder, evidence of the recommending stockholder’s ownership of our common stock and a signed letter from the candidate confirming willingness to
serve  on  our  board  of  directors.  Our  nominating  and  corporate  governance  committee  has  discretion  to  decide  which  individuals  to  recommend  for
nomination as directors.

Under our amended and restated bylaws, stockholders may also nominate candidates for our board of directors. Any nomination must comply with
the requirements set forth in our amended and restated bylaws and should be sent in writing to our Secretary at 400 Chesapeake Drive, Redwood City,
California 94063. To be timely for our 2024 annual meeting of stockholders, our Secretary must receive the nomination no earlier than September 13, 2024
and no later than October 13, 2024.

ITEM 11.    EXECUTIVE COMPENSATION

Processes and Procedures for Compensation Decisions

Our  compensation  committee  is  responsible  for  the  executive  compensation  programs  for  our  executive  officers  and  reports  to  our  board  of
directors on its discussions, decisions and other actions.  Our compensation committee reviews and approves corporate goals and objectives relating to the
compensation  of  our  Chief  Executive  Officer,  evaluates  the  performance  of  our  Chief  Executive  Officer  in  light  of  those  goals  and  objectives  and
determines and approves the compensation of our Chief Executive Officer based on such evaluation.  Our compensation committee has the sole authority to
determine  our  Chief  Executive  Officer’s  compensation.    In  addition,  our  compensation  committee,  in  consultation  with  our  Chief  Executive  Officer,
reviews  and  approves  all  compensation  for  other  officers.  Our  Chief  Executive  Officer  and  Chief  Financial  Officer  also  make  compensation
recommendations  for  our  other  executive  officers  and  initially  propose  the  corporate  and  departmental  performance  objectives  under  our  Executive
Incentive Compensation Plan to the compensation committee.

The compensation committee is authorized to retain the services of one or more executive compensation and benefits consultants or other outside

experts or advisors as it sees fit, in connection with the establishment of our compensation programs and related policies.

Executive Employment Letters

Jeffrey M. Soinski

Pursuant  to  the  employment  letter,  as  revised  on  September  9,  2020,  between  the  Company  and  Jeffrey  M.  Soinski,  our  President  and  Chief
Executive Officer, Mr. Soinski is entitled to receive as compensation (i) a base salary of $400,000, (ii) a discretionary bonus targeted at 75% of his base
salary,  subject  to  the  achievement  of  certain  goals  mutually  agreed  upon  by  him  and  our  board  of  directors  and  payable  semi-annually;  and  (iii)  other
standard benefits provided to each of the Company’s executive officers. The letter has no specific term and provides for at-will employment.

Table of Contents

Pursuant  to  Mr.  Soinski’s  employment  offer  letter,  if,  within  the  12-month  period  following  a  “change  in  control,”  we  terminate  Mr.  Soinski’s
employment without “cause,” or Mr. Soinski resigns for “good reason” (as such terms are defined in Mr. Soinski’s employment offer letter), Mr. Soinski
will receive accelerated vesting as to 100% of his outstanding unvested stock options.  If we experience a change in control, and Mr. Soinski remains our
employee through such date, Mr. Soinski will receive accelerated vesting as to 50% of his outstanding unvested stock options and/or restricted stock.

If we terminate Mr. Soinski without cause at any time, he will be entitled to receive 12 months of base salary and COBRA medical and dental
insurance coverage, in each case payable in substantially equal installments in accordance with our payroll practices, as severance, in exchange for signing
and not revoking a severance agreement and general release against us and our affiliates within 60 days following his termination of employment. 

401(k) Plan

We maintain a tax-qualified retirement plan that provides eligible employees with an opportunity to save for retirement on a tax advantaged basis. 
We may make a discretionary matching contribution to the 401(k) plan, and may make a discretionary employer contribution to each eligible employee
each year.  To date, we have not made any matching or profits sharing contributions into the 401(k) plan.  All participants’ interests in our matching and
profit sharing contributions, if any, vest pursuant to a four-year graded vesting schedule from the time of contribution.  Pre-tax contributions are allocated to
each participant’s individual account and are then invested in selected investment alternatives according to the participants’ directions.  The 401(k) plan is
intended to qualify under Sections 401(a) and 501(a) of the Code.  As a tax-qualified retirement plan, contributions to the 401(k) plan and earnings on those
contributions are not taxable to the employees until distributed from the 401(k) plan, and all contributions are deductible by us when made.

Pension Benefits and Nonqualified Deferred Compensation

We  do  not  provide  a  pension  plan  for  our  employees,  and  none  of  our  named  executive  officers  participated  in  a  nonqualified  deferred

compensation plan in 2023.

Potential Payments upon Termination or Change of Control

Jeffrey M. Soinski

In March 2018, we entered into a change of control and severance agreement with Jeffrey M. Soinski, which was subsequently amended in March
2020. Under this agreement, as amended, if, within the 18 month period following a “change of control,” we terminate Mr. Soinski’s employment other
than for “cause,” death or disability, or the employee resigns for “good reason” (as such terms are defined in the employee’s employment agreement) and,
within 60 days following the employee’s termination, the employee executes an irrevocable separation agreement and release of claims, the employee is
entitled to receive (i) continuing payments of severance pay at a rate equal to the employee’s monthly base salary and pro-rated target bonus, as then in
effect, for a period of 12 months plus one month for every year of service completed for the Company (provided that such severance shall not exceed 18
months), (ii) reimbursement of premiums to maintain group health insurance continuation benefits pursuant to “COBRA” for employee and employee’s
dependents for up to 12 months, (iii) accelerated vesting as to 100% of the employee’s outstanding unvested stock options and/or restricted stock, and (iv)
the extension of the post-termination exercise period of any options held by the employee for a period of 1 year.  Additionally, if we experience a change in
control, 50% of Mr. Soinski’s outstanding unvested stock options and/or restricted stock will vest. In the event of any conflict between Mr. Soinski’s change
of control and severance agreement and his offer letter, described above under “Executive Employment Letters,” he will be entitled to the greater of the
benefits provided by either. The agreement also provides that if the employee is employed by the Company or the Company’s successor on the date that is
12 months following a change of control, then the employee will be entitled to a lump sum bonus payment in an amount equal to what the employee would
have received as a severance payment if the employee had been terminated other than for cause, death or disability.

Himanshu Patel

We previously entered into a change of control and severance agreement with Himanshu Patel, which was subsequently amended in March 2020.
Under this agreement, as amended, if, within the 18 month period following a “change of control,” we terminate Mr. Patel’s employment other than for
“cause,” death or disability, or the employee resigns for “good reason” (as such terms are defined in the employee’s employment agreement) and, within 60
days following the employee’s termination, the employee executes an irrevocable separation agreement and release of claims, the employee is entitled to
receive (i) continuing payments of severance pay at a rate equal to the employee’s monthly base salary and pro-rated target bonus, as then in effect, for a
period of 12 months plus one month for every year of service completed for the Company (provided that such severance shall not exceed 18 months), (ii)
reimbursement of premiums to maintain group health insurance continuation benefits pursuant to “COBRA” for employee and employee’s dependents for
up to 12 months, (iii) accelerated vesting as to 100% of the employee’s outstanding unvested stock options and/or restricted stock, and (iv) the extension of
the  post-termination  exercise  period  of  any  options  held  by  the  employee  for  a  period  of  1  year.  The  agreement  also  provides  that  if  the  employee  is
employed by the Company or the Company’s successor on the date that is 12 months following a change of control, then the employee will be entitled to a
lump sum bonus payment in an amount equal to what the employee would have received as a severance payment if the employee had been terminated other
than for cause, death or disability.

Nabeel Subainati

We  previously  entered  into  a  change  in  control  agreement  with  Mr.  Subainati,  which  we  subsequently  amended  in  March  2023.  Under  the
agreement, as amended, we agreed that if, within the 18 month period following a “change of control,” we terminate Mr. Subainati’s employment other than
for “cause” or death or disability, or if the employee resigns for “good reason” (as such terms are defined in the employee’s employment agreement) and,
within 60 days following the employee’s termination, the employee executes an irrevocable separation agreement and release of claims, the employee is
entitled to receive (i) continuing payments of severance pay at a rate equal to the employee’s base salary and target bonus, as then in effect, for six months
plus one month for every year of service completed for the Company (provided that such severance shall not exceed 12 months), (ii) reimbursement of
premiums to maintain group health insurance continuation benefits pursuant to “COBRA” for the employee and the employee’s dependents for up to six
months, (iii) accelerated vesting as to 100% of the employee’s outstanding unvested stock options and/or restricted stock, and (iv) the extension of the post-
termination exercise period of any options held by the employee for a period of 1 year. Additionally, if we experience a change in control, 50% of Mr.
Subainati’s outstanding unvested stock options and/or restricted stock will vest. The agreement, as amended, also provides that if the employee is employed
by us or our successor on the date that is 12 months following a change of control, then the employee will be entitled to a lump sum bonus payment in an
amount  equal  to  what  the  employee  would  have  received  as  a  severance  payment  if  the  employee  had  been  terminated  other  than  for  cause,  death  or
disability.

Executive Incentive Compensation Plan

Our board of directors has adopted an Executive Incentive Compensation Plan, or the Bonus Plan, which is administered by our compensation
committee.  The Bonus Plan allows our compensation committee to provide cash incentive awards to selected employees, including our named executive
officers, based upon performance goals established by our compensation committee.

Under the Bonus Plan, our compensation committee determines the performance goals applicable to any award, which goals may include, without
limitation:  attainment  of  research  and  development  milestones,  sales  bookings,  business  divestitures  and  acquisitions,  cash  flow,  cash  position,  earnings
(which  may  include  any  calculation  of  earnings,  including  but  not  limited  to  earnings  before  interest  and  taxes,  earnings  before  taxes,  earnings  before
interest,  taxes,  depreciation  and  amortization  and  net  earnings),  earnings  per  share,  net  income,  net  profit,  net  sales,  operating  cash  flow,  operating
expenses, operating income, operating margin, overhead or other expense reduction, product defect measures, product release timelines, productivity, profit,
return on assets, return on capital, return on equity, return on investment, return on sales, revenue, revenue growth, sales results, sales growth, stock price,
time  to  market,  total  stockholder  return,  working  capital,  and  individual  objectives  such  as  peer  reviews  or  other  subjective  or  objective  criteria. 
Performance  goals  that  include  our  financial  results  may  be  determined  in  accordance  with  GAAP  or  such  financial  results  may  consist  of  non-GAAP
financial measures and any actual results may be adjusted by the compensation committee for one-time items or unbudgeted or unexpected items when
performance  goals  that  include  our  financial  results  may  be  determined  in  accordance  with  GAAP,  or  such  financial  results  may  consist  of  non-GAAP
financial measures, and any actual results may be adjusted by the compensation committee for one-time items or unbudgeted or unexpected items when
determining whether the performance goals have been met.  The goals may be on the basis of any factors the compensation committee determines relevant,
and may be adjusted on an individual, divisional, business unit or company-wide basis.  The performance goals may differ from participant to participant
and from award to award.

Our compensation committee may, in its sole discretion and at any time, increase, reduce or eliminate a participant’s actual award, and/or increase,
reduce or eliminate the amount allocated to the bonus pool for a particular performance period.  The actual award may be below, at or above a participant’s
target award, in the compensation committee’s discretion.  Our compensation committee may determine the amount of any reduction on the basis of such
factors as it deems relevant, and it is not required to establish any allocation or weighting with respect to the factors it considers.

Actual awards are paid in cash only after they are earned, which usually requires continued employment through the date a bonus is paid.  Our
compensation committee has the authority to amend, alter, suspend or terminate the Bonus Plan provided such action does not impair the existing rights of
any participant with respect to any earned bonus.

Retention Bonuses

On  March  9,  2021,  the  Compensation  Committee  (the  “Committee”)  of  the  Board  of  Directors  of  the  Company  determined  to  provide  certain
incentive payments (the “Retention Bonuses”) to certain full-time executive officers and vice presidents of the Company, including Jeffrey M. Soinski, and
Himanshu Patel, who serve as the Company’s Chief Executive Officer and Chief Technology Officer, respectively (the “Bonus Officers”), based on certain
performance goals. The Retention Bonus consists of incentive payments in an amount equal to 100% of such Bonus Officer’s annual salary as of December
31, 2023, 50% of which will be paid if such Bonus Officer is in good standing in their service at the Company on December 31, 2023, and 50% to be paid if
such Bonus Officer is in good standing in their service at the Company on December 31, 2024 (each, a “Retention Bonus Payment”). The Retention Bonus
Payments  may  be  paid  in  cash  or  equity,  or  a  combination  of  both,  as  determined  by  the  Committee.  In  addition,  the  Retention  Bonus  Payments  shall
accelerate in the event of a Change in Control, as defined in the Company’s Amended and Restated 2015 Equity Incentive Plan, provided that the Bonus
Officer remains in his or her respective position through such Change in Control. Each Retention Bonus Payment shall be increased in the event that the
price of the common stock of the Company is above $900.00 (subject to adjustment for any stock splits, reverse stock splits, or similar transactions) as of
the date of such Retention Bonus Payment, according to the schedule below:

● If the stock price is between $900.00 and $1,199.99 (subject to adjustment for any stock splits, reverse stock splits, or similar transactions) as of

the date of the Retention Bonus Payment, such Retention Bonus Payment shall be increased by 25%;

● If the stock price is between $1,200.00 and $1,499.99 (subject to adjustment for any stock splits, reverse stock splits, or similar transactions) as of

the date of the Retention Bonus Payment, such Retention Bonus Payment shall be increased by 50%; and

●  If the stock price is $1,500.00 or above (subject to adjustment for any stock splits, reverse stock splits, or similar transactions) as of the date of the

Retention Bonus Payment, such Retention Bonus Payment shall be increased by 100%.

The Retention Bonuses are in addition to any other bonus to which the Bonus Officers may be entitled under the Company’s Bonus Plan.

On October 24, 2023, the Committee determined to provide the Retention Bonuses to Nabeel Subainati, the Company’s Vice President, Finance;
provided, however, that Mr. Subainati will not be eligible to receive the Retention Bonus Payment payable with respect to his continuing employment as of
December 31, 2023.

In satisfaction of these retention bonus payment obligations for a number of employees, we paid a total of $0.9 million in the form of RSAs on
January 16, 2024. Pursuant to the retention bonus terms as approved by the Committee, we may elect to pay these incentive payments in either cash or
equity, or a combination of both. On January 11, 2024, the Committee approved the aforementioned payment in the form of RSAs.

Specifically,  we  granted  a  total  of  317,314  shares  of  RSAs  which  vested  immediately  upon  grant.  To  satisfy  all  associated  income  and  other
statutory tax obligations on behalf of the various employees, we employed a withhold-to-cover payment method. Consequently, 123,285 RSA shares were
withheld resulting in a net issuance of common shares to employees totaling 194,029. We measured the fair value of RSAs using the closing stock price of a
share of the Company’s common stock of $2.70 on the day of grant.

Director Compensation

Our board of directors approved our Outside Director Compensation Policy in January 2015 to compensate each non-employee director for his or
her service and amended certain aspects of this policy in August 2018.  Our board of directors will have the discretion to revise non-employee director
compensation as it deems necessary or appropriate.  Under our Outside Director Compensation Policy, non-employee directors will receive compensation
in the form of equity and cash, as described below:

Cash Compensation.  All non-employee directors will be entitled to receive the following cash compensation for their services:

● $35,000 per year for service as a board member;

● $25,000 per year additionally for service as chairman of the board;

● $20,000 per year additionally for service as chairman of the audit committee;

● $10,000 per year additionally for service as an audit committee member;

● $15,000 per year additionally for service as chairman of the compensation committee;

● $7,500 per year additionally for service as a compensation committee member;

● $10,000 per year additionally for service as chairman of the nominating and corporate governance committee; and

● $5,000 per year additionally for service as a nominating and corporate governance committee member.

All  cash  payments  to  non-employee  directors,  or  the  Retainer  Cash  Payments,  will  be  paid  semiannually  with  the  first  semiannual  installment
payable on the date of our annual meeting of stockholders or, if no annual meeting occurs in a given year, May 1, and the second semiannual installment
payable on November 1 of each year.

Election  to  Receive  RSUs  or  RSAs  in  Lieu  of  Cash  Payments.   All  non-employee  directors  may  elect  to  convert  a  Retainer  Cash  Payment  into
RSUs or RSAs, or Retainer RSAs, with a grant date fair value equal to the applicable Retainer Cash Payment.  Each Retainer RSA will be granted on the
date  that  the  applicable  Retainer  Cash  Payment  was  scheduled  to  be  paid,  and  all  of  the  shares  underlying  the  Retainer  RSAs  will  vest  and  become
exercisable six months from the date of grant, subject to continued service as a director through the applicable vesting date.  The Retainer RSAs will be
subject to certain terms and conditions as described below under the section titled “Director Compensation—Equity Compensation.”

Elections to convert a Retainer Cash Payment into a Retainer RSA must generally be made on or prior to December 31 of the year prior to the year
in  which  the  Retainer  Cash  Payment  is  scheduled  to  be  paid,  or  such  earlier  deadline  as  is  established  by  our  board  of  directors  or  compensation
committee.  A newly appointed non-employee director will be permitted to elect to convert Retainer Cash Payments payable in the same calendar year into
Retainer RSAs, provided that such election is made prior to the date the individual becomes a non-employee director.

Equity  Compensation.    Nondiscretionary,  automatic  grants  of  RSUs  or  RSAs  (collectively  referred  to  as  “RSAs”)  will  be  made  to  our  non-

employee directors.

● Initial Grant.  Generally, each person who first becomes a non-employee director will be granted RSAs having a grant date fair value equal to
$115,000,  or  the  Initial  Grant.    The  Initial  Grant  will  typically  be  granted  on  the  date  of  the  first  meeting  of  our  board  of  directors  or
compensation committee occurring on or after the date on which the individual first became a non-employee director.  The Initial Grant will
vest  and  become  exercisable  as  to  one  thirty-sixth  (1/36th)  of  the  shares  subject  to  such  Initial  Grant  on  each  monthly  anniversary  of  the
commencement  of  the  non-employee  director’s  service  as  a  director,  subject  to  the  continued  service  as  a  director  through  the  applicable
vesting date.

● Annual Grant.  Once each calendar year, on the same date that our board of directors grants annual equity awards to our senior executives,
each non-employee director will be granted RSAs having a grant date fair value equal to $75,000, or the Annual Grant.  All of the shares
underlying  the  Annual  Grant  will  vest  and  become  exercisable  one  year  from  the  date  of  grant,  subject  to  continued  service  as  a  director
through the applicable vesting date.

Table of Contents

The grant date fair value is the closing sales price for the Company’s common stock (or the closing bid, if no sales were reported) as quoted on

such exchange or system on the date such award is granted.

Any RSAs granted under our outside director compensation policy will fully vest and become exercisable in the event of a change in control, as
defined in our 2015 Plan, provided that the holder remains a director through such change in control.  Further, our 2015 Plan provides that in the event of a
merger  or  change  in  control,  as  defined  in  our  2015  Plan,  each  outstanding  equity  award  granted  under  our  2015  Plan  that  is  held  by  a  non-employee
director  will  fully  vest,  all  restrictions  on  the  shares  subject  to  such  award  will  lapse  and,  with  respect  to  awards  with  performance-based  vesting,  all
performance goals or other vesting criteria will be deemed achieved at 100% of target levels, and all of the shares subject to such award will become fully
exercisable, if applicable, provided such optionee remains a director through such merger or change in control.

December 31, 2023.

Directors  who  are  also  our  employees  receive  no  additional  compensation  for  their  service  as  directors.    During  2023,  Jeffrey  M.  Soinski,  our
President,  Chief  Executive  Officer  and  a  director,  was  also  our  employee.    See  the  section  titled  “Summary  Compensation  Table”  below  for  additional
information about the compensation for Mr. Soinski.

Officer and Director Share Purchase Plan

On August 22, 2018, the Board of Directors of the Company approved the adoption of an Officer and Director Share Purchase Plan (“ODPP”),
which allowed executive officers and directors to purchase shares of our common stock at fair market value in lieu of salary or, in the case of directors,
director fees. Eligible individuals were allowed voluntarily participate in the ODPP by authorizing payroll deductions or, in the case of directors, deductions
from director fees for the purpose of purchasing common stock. Elections to participate in the ODPP may only be made during open trading windows under
our insider trading policy when the participant does not otherwise possess material non-public information concerning the Company. There was no common
stock  issued  under  the  ODPP  during  either  the  year  ended  December  31,  2022  or  2021.  On  May  16,  2022,  the  Board  of  Directors  of  the  Company
terminated the Amended and Restated Officer and Director Share Purchase Plan due to the administrative costs of maintaining such plan and the limited
amount of remaining shares. Consequently, there are no longer any shares reserved for issuance under this plan.

Security Ownership of Certain Beneficial Owners and Management

The following table sets forth certain information with respect to the beneficial ownership of our capital stock as of March 1, 2024 for:

● each person or group of affiliated persons known by us to be the beneficial owner of more than 5% of our common stock;

● each of our named executive officers;

● each of our directors and nominees for director; and

● all of our current executive officers and directors as a group.

We  have  determined  beneficial  ownership  in  accordance  with  the  rules  and  regulations  of  the  SEC,  and  the  information  is  not  necessarily
indicative of beneficial ownership for any other purpose.  Except as indicated by the footnotes below, we believe, based on information furnished to us, that
the  persons  and  entities  named  in  the  table  below  have  sole  voting  and  sole  investment  power  with  respect  to  all  shares  of  our  capital  stock  that  they
beneficially own, subject to applicable community property laws.

Applicable percentage ownership is based on 1,511,107 shares of our common stock outstanding as of March 1, 2024. In computing the number of
shares of capital stock beneficially owned by a person and the percentage ownership of such person, we deemed to be outstanding all shares of our capital
stock subject to options, restricted stock awards (“RSAs”) or RSUs held by the person that are currently exercisable, exercisable or vests within 60 days of
March 1, 2024.  However, we did not deem such shares of our capital stock outstanding for the purpose of computing the percentage ownership of any other
person.

ITEM 13.    CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

Related Person Transactions

We describe below transactions and series of similar transactions, since January 1, 2022, to which we were a party or will be a party, in which:

● the  amounts  involved  exceeded  or  will  exceed  the  lesser  of  $120,000  or  1%  of  the  average  of  our  total  assets  at  year-end  for  the  last  two

completed fiscal years; and

● any of our directors, nominees for director, executive officers or beneficial holders of more than 5% of our outstanding common stock, or any
immediate family member of, or person sharing the household with, any of these individuals or entities (each, a related person), had or will
have a direct or indirect material interest.

Employment and Indemnification Agreements

We have entered into employment and separation arrangements with certain current and former executive officers.  For more information on these
employment and separation agreements, see the section titled “Executive Compensation - Executive Employment Letters” and “Executive Compensation –
Potential Payments upon Termination or Change of Control” in Item 11 above.

We  have  entered  into  indemnification  agreements  with  our  directors  and  executive  officers.    The  indemnification  agreements,  as  well  as  our

certificate of incorporation and bylaws, require us to indemnify our directors and executive officers to the fullest extent permitted by Delaware law.

Transactions with CRG

As  described  elsewhere  in  this  Annual  Report  on  Form  10-K,  we  have  entered  into  various  transactions  with  CRG.  On  August  2,  2023,  CRG
became a beneficial holder of greater than 5% of our outstanding common stock. As a result, the ongoing CRG agreements and transactions entered into at
the time of the Zylox-Tonbridge private placement are considered related party transactions including the following:

On September 22, 2015, the Company entered into a Term Loan Agreement, as amended (the “Loan Agreement”) with CRG under which, subject
to certain conditions, the Company had the right to borrow up to $50 million in principal amount from CRG on or before the end of the twenty-fourth (24th)
month period commencing on the first Borrowing Date (as defined in the Loan Agreement). The Company borrowed $30 million on September 22, 2015.
The Company borrowed an additional $10 million on June 15, 2016 under the Loan Agreement.

On  February  14,  2018,  the  Company  and  CRG  further  amended  the  Loan  Agreement  concurrent  with  the  conversion  of  $38  million  of  the
principal amount of the senior secured term loan (plus $3.8 million in back-end fees and prepayment premium applicable thereto) into a newly authorized
Series A convertible preferred stock.

On August 2, 2023, the Company and CRG entered into a Securities Purchase Agreement (“SPA”) pursuant to which the Company issued 1,920
shares of a newly authorized Series E convertible preferred stock (“Series E preferred stock”) in exchange for CRG surrendering for cancellation $1.92
million of outstanding principal and accrued interest of the senior secured term loan under the Loan Agreement (the “Term Loan Agreement”). Each share
of Series E preferred stock has a stated value of $1,000 per share and is convertible into 93 shares of the Company’s common stock at a conversion price of
$10.725 per share, provided that the shares of Series E preferred stock cannot be converted into common stock to the extent the applicable holder would
beneficially  own  in  excess  of  19.99%  of  the  Company’s  outstanding  voting  power,  unless  approved  by  the  Company's  stockholders  in  accordance  with
Nasdaq Listing Rule 5635(b).

Table of Contents

The  Company  has  entered  into  several  amendments  to  the  Loan  Agreement  (the  “Amendments”)  with  CRG  since  September  2015.  The
Amendments, among other things: (1) extended the interest-only period through December 31, 2026; (2) extended the period during which the Company
may elect to pay a portion of interest in payment-in-kind (“PIK”), interest payments through December 31, 2026 so long as no Default (as defined in the
Loan Agreement) has occurred and is continuing; (3) permitted the Company to make the entire interest payments in PIK interest payments for through
December 31, 2026 so long as no Default has occurred and is continuing; (4) extended the Stated Maturity Date (as defined in the Loan Agreement) to
December 31, 2025; (5) reduced the minimum liquidity covenant to $3.5 million at all times; (6) eliminated the minimum revenue covenants for all years
(7) changed the date under the on-going stand-alone representation regarding no “Material Adverse Change” to December 31, 2020; (8) amended the on-
going stand-alone representation and stand-alone Event of Default (as defined in the Loan Agreement) regarding Material Adverse Change such that any
adverse change in or effect upon the revenue of the Company and its subsidiaries due to the outbreak of COVID-19 will not constitute a Material Adverse
Change; (9) provided CRG with board observer rights and (10) provide that the board observer may be appointed or removed by written notice from the
Majority Lenders (as defined in the Loan Agreement).

On  January  26,  2024,  the  Company  entered  into  Amendment  No.  7  to  the  Loan  Agreement  with  CRG,  which  reduces  the  minimum  liquidity
requirement of the Loan Agreement from $3.5 million to $1.0 million until April 1, 2024. Thereafter, the Company will be subject to the minimum liquidity
requirement of $3.5 million.

On March 5, 2024, the Company entered into Amendment No. 9 to the Loan Agreement with CRG, which (1) extended the interest-only period
through December 31, 2026; (2) extended the period during which the Company may elect to pay a portion of interest in payment-in-kind (“PIK”), interest
payments through December 31, 2026 so long as no Default (as defined in the Loan Agreement) has occurred and is continuing; (3) permitted the Company
to make the entire interest payments in PIK interest payments for through December 31, 2026 so long as no Default has occurred and is continuing; and (4)
permit the payment of dividends on the preferred stock issued or issuable to the Purchaser, as defined in Footnote 14. Refer therein for details.

Under the amended Loan Agreement, no cash payments for either principal or interest are required until the first quarter of 2027. The interest will
be accrued and included in the debt balance based (to the extent not paid) on principal amounts outstanding at the beginning of the quarter at an interest rate
of 12.5%. Beginning in the first quarter of 2027, the Company will be required to make quarterly principal payments (in addition to the interest) of $2.4
million with total principal payments of $9.4 million in 2027 and $9.4 million in 2028. The maturity date of the Loan (as defined in the Loan Agreement) is
December 31, 2028.

The  Company  may  voluntarily  prepay  the  borrowings  in  full,  with  a  prepayment  premium  beginning  at  5.0%  and  declining  by  1.0%  annually
thereafter, with no premium being payable if prepayment occurs after seven and half years of the loan. Each tranche of borrowing required the payment, on
the borrowing date, of a financing fee equal to 1.5% of the borrowed loan principal, which is recorded as a discount to the debt. In addition, a facility fee
equal  to  15.0%  of  the  amounts  borrowed  plus  any  PIK  is  to  be  payable  at  the  end  of  the  term  or  when  the  borrowings  are  repaid  in  full.  A  long-term
liability is being accreted using the effective interest method for the facility fee over the term of the Loan Agreement with a corresponding discount to the
debt. The borrowings are collateralized by a security interest in substantially all of the Company’s assets.

The Loan Agreement requires that the Company adheres to certain affirmative and negative covenants, including financial reporting requirements,
certain minimum financial covenants for pre-specified liquidity and a prohibition against the incurrence of indebtedness, or creation of additional liens,
other than as specifically permitted by the terms of the Loan Agreement. In particular, the covenants of the amended Loan Agreement included a covenant
that the Company maintain a minimum of $3.5 million of cash and certain cash equivalents. The minimum liquidity requirement was temporarily reduced
to  $1.0  million  until  April  1,  2024.  In  addition,  the  Loan  Agreement  prohibits  the  payment  of  cash  dividends  on  the  Company’s  capital  stock  and  also
places  restrictions  on  mergers,  sales  of  assets,  investments,  incurrence  of  liens,  incurrence  of  indebtedness  and  transactions  with  affiliates.  CRG  may
accelerate the payment terms of the Loan Agreement upon the occurrence of certain “Events of Default” set forth therein, which include the failure of the
Company to make timely payments of amounts due under the Loan Agreement, the failure of the Company to adhere to the covenants set forth in the Loan
Agreement, the insolvency of the Company or upon the occurrence of a “Material Adverse Change” thereunder.

Policies and Procedures for Related Party Transactions

Our board of directors has adopted a written policy that our executive officers, directors, nominees for election as a director, beneficial owners of
more than 5% of any class of our common stock and any members of the immediate family of any of the foregoing persons are not permitted to enter into a
related person transaction with us without the prior consent of our audit committee.  Any request for us to enter into a transaction with an executive officer,
director, nominee for election as a director, beneficial owner of more than 5% of any class of our common stock or any member of the immediate family of
any of the foregoing persons in which the amount involved exceeds the lesser of $120,000 or 1% of the average of our total assets at year-end for the last
two completed fiscal years and such person would have a direct or indirect interest must first be presented to our audit committee for review, consideration
and approval.  In approving or rejecting any such proposal, our audit committee is to consider the material facts of the transaction, including, but not limited
to, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third-party under the same or similar circumstances
and the extent of the related person’s interest in the transaction.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Shareholders and the Board of Directors of
Avinger, Inc.

Opinion on the Financial Statements

We  have  audited  the  accompanying  balance  sheets  of  Avinger,  Inc.  (the  “Company”)  as  of  December  31,  2023  and  2022,  the  related  statements  of
operations and comprehensive loss, stockholders’ equity (deficit), and cash flows for the years then ended, and the related notes and the financial statement
schedules (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial
position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for the years then ended, in conformity with
accounting principles generally accepted in the United States of America.

Going Concern Uncertainty

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the
financial statements, the Company’s recurring losses from operations and its need for additional capital raise substantial doubt about its ability to continue
as a going concern. Management’s plans in regard to these matters are also described in Note 1. The financial statements do not include any adjustments
that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial
statements  based  on  our  audits.  We  are  a  public  accounting  firm  registered  with  the  Public  Company  Accounting  Oversight  Board  (United  States)
(“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules
and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor
were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of
internal  control  over  financial  reporting  but  not  for  the  purpose  of  expressing  an  opinion  on  the  effectiveness  of  the  Company’s  internal  control  over
financial reporting. Accordingly, we express no such opinion.

Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial  statements,  whether  due  to  error  or  fraud,  and
performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in
the  financial  statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as
evaluating the overall presentation of the financial statements. We believe that our audits provides a reasonable basis for our opinion.

Critical Audit Matter

The  critical  audit  matter  communicated  below  is  a  matter  arising  from  the  current  period  audit  of  the  financial  statements  that  was  communicated  or
required  to  be  communicated  to  the  audit  committee  and  that  (1)  relates  to  accounts  or  disclosures  that  are  material  to  the  financial  statements  and  (2)
involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion
on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical
audit matter or on the accounts or disclosures to which it relates.

Write-down of Excess and Obsolete Inventories

As described in Note 2 and 4 to the financial statements, the Company’s inventories balance was $5.3 million as of December 31, 2023. The Company
values its inventories at lower of cost (determined using the first-in, first-out method) or net realizable value. The Company writes down inventory that has
expired or become obsolete, inventory that has a cost basis in excess of its expected net realizable value, and inventory in excess of expected requirements.
The estimate of excess quantities is subjective and primarily dependent on the estimates of future demand for a particular product. Changes in assumptions
of product demand could have a significant impact on the amount of write-down recorded. The evaluation by management includes analysis of historical
sales levels by product, projections of future demand, the risk of technological or competitive obsolescence for products, general market conditions, as well
as the feasibility of reworking or using excess or obsolete products or components in the production or assembly of other products that are not obsolete or
for which there are not excess quantities in inventory.

We identified auditing the write-down of excess and obsolete inventories, in particular the estimates for excess quantities and obsolescence, as a critical
audit matter because of the significant assumptions and subjective judgments used by management, which involved significant audit effort and the use of
especially challenging and subjective auditor judgment when performing audit procedures and evaluating the results of those procedures.

The primary procedures we performed to address the critical audit matter included:

● Evaluating management’s process and methodology for developing the estimates of excess and obsolete inventories.

● Identifying and testing significant assumptions utilized by management and evaluating the reasonableness of the significant assumptions used by:

● Evaluating sales forecasts and comparing management’s prior period sales forecasts to actual results.

● Performing inquiries with non-financial personnel, including sales and production employees, regarding obsolete or discontinued

inventory items.

● Evaluating the appropriateness of the formulaic calculation and subjective management adjustments by product type.

● Testing the completeness, accuracy, and relevance of the underlying data used in the estimate including:

● Testing the calculations related to the application of the methodology to specific inventory categories and recalculation.

● Performing inquiries as to whether inventory items without recent sales are reserved for.

● Performing analytical procedures over the excess and obsolescence reserve based on historical trends for reasonableness.

Organization, Nature of Business

AVINGER, INC.

Notes to Financial Statements

Avinger, Inc. (the “Company”), a Delaware corporation, was incorporated in March 2007. The Company designs, manufactures and sells image-
guided, catheter-based systems that are used by physicians to treat patients with peripheral artery disease (“PAD”). Patients with PAD have a build-up of
plaque  in  the  arteries  that  supply  blood  to  areas  away  from  the  heart,  particularly  the  pelvis  and  legs.  The  Company  manufactures  and  sells  a  suite  of
products in the United States (“U.S.”) and in select international markets. The Company has developed its Lumivascular platform, which integrates optical
coherence tomography (“OCT”) visualization with interventional catheters and is the industry’s only system that provides real-time intravascular imaging
during the treatment portion of PAD procedures. The Company’s Lumivascular platform consists of a capital component, Lightbox consoles, as well as a
variety of disposable catheter products. The Company’s current catheter products include Ocelot, Tigereye and Tigereye ST, which are designed to allow
physicians  to  penetrate  a  total  blockage  in  an  artery,  known  as  a  chronic  total  occlusion  (“CTO”).  The  Company  also  has  image-guided  atherectomy
products,  Pantheris,  Pantheris  SV  and  Pantheris  LV,  which  are  designed  to  allow  physicians  to  precisely  remove  arterial  plaque  in  PAD  patients.  The
Company is in the process of developing next-generation CTO crossing devices to target coronary CTO markets. The Company is located in Redwood City,
California.

Liquidity Matters

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates the
realization of assets and the satisfaction of liabilities in the normal course of business. The Financial Accounting Standards Board (“FASB”) Accounting
Standards Update (“ASU”) No. 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40) requires the Company to make certain
disclosures  if  it  concludes  that  there  is  substantial  doubt  about  the  entity’s  ability  to  continue  as  a  going  concern  within  one  year  from  the  date  of  the
issuance of these financial statements.

In the course of its activities, the Company has incurred losses and negative cash flows from operations since its inception. On March 5, 2024, the
Company entered into a financing as part of a broader strategic collaboration with Zylox-Tonbridge Medical Technology Co., Ltd. (“Zylox-Tonbridge”) in
which the Company received an aggregate of $7.5 million before any commissions, legal and accounting fees, and other ancillary expenses as described
more  fully  within  Note  14,  Subsequent  Events.  As  of  December  31,  2023,  the  Company  had  an  accumulated  deficit  of  $420.7  million.  The  Company
expects to incur losses for the foreseeable future. The Company believes that its cash and cash equivalents of $5.3 million at December 31, 2023 together
with the aforementioned March 2024 financing, together with debt and other financing activities and expected revenues from operations will be sufficient to
allow the Company to fund its current operations through the second quarter of 2024. The Company received net proceeds of approximately $4.4 million
from the sale of its common stock in August 2022, $6.5 million from the sale of its common stock under an At The Market Offering Agreement from the
time of activation through the year ended December 31, 2023 and $6.7 million from the sale of Series D preferred stock in January 2022. The Company
may seek to raise additional funds in future equity offerings to meet its operational needs and capital requirements for product development, clinical trials
and commercialization or other strategic objectives.

The  Company  can  provide  no  assurance  that  it  will  be  successful  in  raising  funds  pursuant  to  additional  equity  or  debt  financings  or  that  such
funds  will  be  raised  at  prices  that  do  not  create  substantial  dilution  for  its  existing  stockholders.  Given  the  volatility  in  the  Company’s  stock  price,  any
financing  that  the  Company  may  undertake  in  the  next  twelve  months  could  cause  substantial  dilution  to  its  existing  stockholders,  and  there  can  be  no
assurance  that  the  Company  will  be  successful  in  acquiring  additional  funding  at  levels  sufficient  to  fund  its  various  endeavors.  These  conditions  raise
substantial doubt about the Company’s ability to continue as a going concern. In addition, the macroeconomic environment has in the past resulted in and
could continue to result in reduced consumer and investor confidence, instability in the credit and financial markets, volatile corporate profits and reduced
business and consumer spending, which could increase the cost of capital and/or limit the availability of capital to the Company.

If  the  Company  is  unable  to  raise  additional  capital  in  sufficient  amounts  or  on  terms  acceptable  to  it,  the  Company  may  have  to  significantly
reduce its operations or delay, scale back or discontinue the development and sale of one or more of its products. The financial statements do not include
any adjustments that might result from the outcome of this uncertainty. The Company’s ultimate success will largely depend on its continued development
of innovative medical technologies, its ability to successfully commercialize its products and its ability to raise significant additional funding.

Table of Contents

Additionally,  due  to  the  substantial  doubt  about  the  Company’s  ability  to  continue  operating  as  a  going  concern  and  the  “Material  Adverse
Change” clause in the Loan Agreement with CRG Partners III L.P. and certain of its affiliated funds (collectively “CRG”), the entire amount of outstanding
borrowings at December 31, 2023 and 2022 has been classified as current in these financial statements. CRG has not purported that an Event of Default (as
defined in the Loan Agreement) has occurred due to a Material Adverse Change.

Currently substantially all of our cash and cash equivalents are held at a single financial institution, First Citizens Bank, which acquired our prior
banking partner, Silicon Valley Bank in March 2023. On March 10, 2023, the Federal Deposit Insurance Corporation announced that Silicon Valley Bank
had been closed by the California Department of Financial Protection and Innovation. While we have regained access to our accounts at Silicon Valley
Bank and are evaluating our banking relationships, future disruptions of financial institutions where we bank or have credit arrangements, or disruptions of
the financial services industry in general, could adversely affect our ability to access our cash and cash equivalents. If we are unable to access our cash and
cash equivalents as needed, our financial position and ability to operate our business will be adversely affected.

Equity Offerings

January 2022 Offering

On  January  14,  2022,  the  Company  entered  into  a  securities  purchase  agreement  with  several  institutional  investors  pursuant  to  which  the
Company  agreed  to  sell  and  issue,  in  a  registered  direct  offering  (“January  2022  Offering”),  an  aggregate  of  7,600  shares  of  the  Company’s  Series  D
Convertible  Preferred  Stock,  par  value  of  $0.001  per  share,  at  an  offering  price  of  $1,000  per  share  which  was  convertible  into  common  stock  at  a
conversion price of $120.00 per share. Concurrently, the Company agreed to issue to these investors warrants to purchase up to an aggregate of 53,833
shares  of  the  Company’s  common  stock  (the  “Common  Warrants”).  As  a  result,  the  Company  received  aggregate  net  proceeds  of  approximately  $6.7
million after underwriting discounts, commissions, legal and accounting fees, and other ancillary expenses.

The  53,833  Common  Warrants  have  an  exercise  price  of  $144.00  per  share  and  became  exercisable  beginning  July  14,  2022.  The  Common
Warrants will expire five  years  following  the  time  they  become  exercisable,  or  July  14,  2027.  The  Company  also  issued  to  the  Placement  Agent  or  its
designees warrants to purchase up to an aggregate of 4,433 shares of common stock (the “Placement Agent Warrants”). The Placement Agent Warrants are
subject to the same terms as the Common Warrants, except that the Placement Agent Warrants have an exercise price of $150.00 per share and a term of
five years from the commencement of the sales pursuant to the January 2022 Offering, or January 12, 2027.

August 2022 Offering

On  August  4,  2022,  the  Company  entered  into  a  securities  purchase  agreement  with  a  single  institutional  investor  for  the  issuance  and  sale  of
98,935  shares  of  its  common  stock  in  a  registered  direct  offering  (“RD”  or  “Registered  Direct”)  at  a  purchase  price  of  $26.28  per  share,  or  pre-funded
warrants in lieu thereof. In a concurrent private placement, the Company also agreed to issue and sell to the investor 91,324 shares of common stock at the
same purchase price as in the registered direct offering, or pre-funded warrants in lieu thereof (“Private Placement” and together with the Registered Direct
offering  the  “August  2022  Offering”).  As  a  result,  the  Company  received  aggregate  net  proceeds  of  approximately  $4.4  million  after  underwriting
discounts, commissions, legal and accounting fees, and other ancillary expenses.

As  a  result,  in  the  Registered  Direct  offering,  the  Company  issued  (i)  46,667  shares  of  common  stock,  (ii)  and  pre-funded  warrants  in  lieu  of
common  stock  to  purchase  up  to  an  aggregate  of  52,268  shares  of  common  stock  (the  “RD  Pre-Funded  Warrants”)  and  in  the  Private  Placement,  the
Company issued pre-funded warrants to purchase up to an aggregate of 91,324 shares of common stock (the “Private Placement Pre-Funded Warrants” and
together  with  the  RD  Pre-Funded  Warrants  the  “August  2022  Pre-Funded  Warrants”).  As  of  December  31,  2023,  all  the  Private  Placement  Pre-Funded
Warrants were exercised leaving none outstanding.

In  addition,  the  Company  issued  to  the  investor  in  the  August  2022  Offering  Series  A  preferred  investment  options  to  purchase  up  to  190,259
additional shares of the Company’s common stock and Series B preferred investment options to purchase up to 190,259 additional shares of the Company’s
common stock (the “Preferred Investment Options”). The Series A preferred investment options have an exercise price of $22.53 per share, are immediately
exercisable, and will expire five and one-half years from the date of issuance, or February 8, 2028, and the Series B preferred investment options also have
an exercise price of $22.53 per share, are immediately exercisable, and will expire two years from the date of issuance, or August 8, 2024. The Company
also issued to the Placement Agent or its designees preferred investment options to purchase up to an aggregate of 11,416 shares of common stock (the
“Placement  Agent  Preferred  Investment  Options”).  The  Placement  Agent  Preferred  Investment  Options  are  subject  to  the  same  terms  as  the  Preferred
Investment Options, except that the Placement Agent Preferred Investment Options have an exercise price of $32.85 per share and a term of five years from
the commencement of the sales pursuant to the August 2022 Offering, or August 3, 2027.

At The Market Offering Agreement

On May 20, 2022, the Company entered into an At The Market Offering Agreement (the “ATM Agreement”) with H.C. Wainwright & Co., LLC
(the “Agent”), as sales agent, pursuant to which the Company may offer and sell shares of common stock, par value $0.001 per share (the “Shares”) up to
an aggregate offering price of $7,000,000 from time to time, in an at the market public offering. Sales of the Shares are to be made at prevailing market
prices at the time of sale, or as otherwise agreed with the Agent. The Agent will receive a commission from the Company of 3.0% of the gross proceeds of
any Shares sold under the ATM Agreement. The Shares sold under the ATM Agreement are offered and sold pursuant to the Company’s shelf registration
statement on Form S-3, which was initially filed with the Securities and Exchange Commission (the “SEC”) on March 29, 2022 and declared effective on
April 7, 2022, and a prospectus supplement and the accompanying prospectus relating to the At The Market Offering filed with the SEC on May 20, 2022.
During  the  year  ended  December  31,  2022,  the  Company  sold  39,048  shares  of  common  stock  pursuant  to  the  ATM  Agreement  at  an  average  price  of
$25.08 per share for aggregate proceeds of $1.0 million, of which approximately $29,000 was paid in the form of commissions to the Agent. On August 3,
2022, the Company suspended sales under the ATM Agreement. On March 17, 2023, the Company reactivated the ATM Agreement. During the year ended
December 31, 2023, the Company sold 607,241 shares of common stock at an average price of $9.01 per share for aggregate proceeds of approximately
$5.5 million, of which approximately $164,000 was paid in the form of commissions to the Agent. While the Company may attempt additional sales in the
future, there can be no assurance that the Company will be successful in acquiring additional funding through these means.

Other than the ATM Agreement, the Company currently does not have any commitments to obtain additional funds.

2. Summary of Significant Accounting Policies

Basis of Presentation

The  accompanying  financial  statements  have  been  prepared  in  accordance  with  United  States  generally  accepted  accounting  principles  (“U.S.

GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”).

On  March  11,  2022,  the  Company’s  Board  of  Directors  approved  an  amendment  to  the  Company’s  amended  and  restated  certificate  of
incorporation to effect a 1-for-20 reverse stock split of the Company’s issued and outstanding common stock. The reverse stock split became effective on
March 14, 2022.

On  September  8,  2023,  the  Company’s  Board  of  Directors  approved  an  amendment  to  the  Company’s  amended  and  restated  certificate  of
incorporation to effect a 1-for-15 reverse stock split of the Company’s issued and outstanding common stock. The reverse stock split became effective on
September 12, 2023. The par value of the common stock and preferred stock was not adjusted as a result of the reverse stock splits. All common stock,
stock  options,  restricted  stock  units,  restricted  stock  awards  and  per  share  amounts  in  the  financial  statements  have  been  retroactively  adjusted  for  all
periods  presented  to  give  effect  to  the  reverse  stock  splits.  Additionally,  the  common  stock  at  par  and  related  additional  paid-in  capital  amounts  as  of
December 31, 2022 in the balance sheet, the common stock at par and related additional paid-in capital amounts in the Statement of Stockholders’ Equity as
of December 31, 2022 and 2021, and for the year ended December 31, 2022 have also been retroactively reclassified to give effect to the reverse stock
splits.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the
amounts  and  disclosures  reported  in  the  financial  statements.  Management  uses  significant  judgment  when  making  estimates  related  to  its  stock-based
compensation, accruals related to compensation, the valuation of the common stock warrants, provisions for doubtful accounts receivable and excess and
obsolete inventories, clinical trial accruals, and its reserves for sales returns and warranty costs. Management bases its estimates on historical experience
and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments
about the carrying values of assets and liabilities that are not readily apparent from other sources. Although these estimates are based on the Company’s
knowledge  of  current  events  and  actions  it  may  undertake  in  the  future,  actual  results  may  ultimately  materially  differ  from  these  estimates  and
assumptions.

Fair Value of Financial Instruments

The Company has evaluated the estimated fair value of its financial instruments as of December 31, 2023 and 2022. Financial instruments consist
of  cash  and  cash  equivalents,  accounts  receivable  and  payable,  and  other  current  liabilities  and  borrowings.  The  carrying  amounts  of  cash  and  cash
equivalents, accounts receivable and payable, and other current liabilities approximate their respective fair values because of the short-term nature of those
instruments. Based upon the borrowing terms and conditions currently available to the Company, the carrying values of the borrowings approximate their
fair value.

F-10

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

Cash and Cash Equivalents

The  Company  considers  all  highly  liquid  investments  with  an  original  maturity  of  three  months  or  less  at  the  time  of  purchase  to  be  cash
equivalents. Cash equivalents are considered available-for-sale marketable securities and are recorded at fair value, based on quoted market prices. As of
December 31, 2023 and 2022, the Company’s cash equivalents are entirely comprised of investments in money market funds. Any related unrealized gains
and losses are recorded in other comprehensive income (loss) and included as a separate component of stockholders’ equity. There were no unrealized gains
and  losses  as  of  December  31,  2023  and  2022.  Any  realized  gains  and  losses  and  interest  and  dividends  on  available-for-sale  securities  are  included  in
interest income or expense and computed using the specific identification cost method.

Concentration of Credit Risk, and Other Risks and Uncertainties

Financial instruments that potentially subject the Company to credit risk consist of cash and cash equivalents and accounts receivable to the extent

of the amounts recorded on the balance sheets.

The  Company’s  policy  is  to  invest  in  cash  and  cash  equivalents,  consisting  of  money  market  funds.  These  financial  instruments  are  held  in
Company accounts at one financial institution, First Citizens Bank, which acquired our prior banking partner, Silicon Valley Bank, in March 2023. The
counterparties to the agreements relating to the Company’s investments consist of financial institutions of high credit standing. The Company provides for
uncollectible  amounts  when  specific  credit  problems  arise.  Management’s  estimates  for  uncollectible  amounts  have  been  adequate,  and  management
believes  that  all  significant  credit  risks  have  been  identified  at  December  31,  2023  and  2022.  On  March  10,  2023,  the  Federal  Deposit  Insurance
Corporation  announced  that  Silicon  Valley  Bank  had  been  closed  by  the  California  Department  of  Financial  Protection  and  Innovation.  While  we  have
regained access to our accounts at First Citizens Bank, formerly Silicon Valley Bank and are evaluating our banking relationships, future disruptions of
financial  institutions  where  we  bank  or  have  credit  arrangements,  or  disruptions  of  the  financial  services  industry  in  general,  could  adversely  affect  our
ability to access our cash and cash equivalents. If we are unable to access our cash and cash equivalents as needed, our financial position and ability to
operate our business will be adversely affected.

The Company’s accounts receivable are due from a variety of healthcare organizations in the United States and select international markets. The
Company provides for uncollectible amounts when specific credit problems arise. Management’s estimates for uncollectible amounts have been adequate,
and  management  believes  that  all  significant  credit  risks  have  been  identified  at  December  31,  2023  and  2022.  At  December  31,  2023,  there  was  one
customer that represented 24% of the Company’s accounts receivable, whereas at December 31, 2022, there was no customer that represented 10% or more
of the Company’s accounts receivable. For the years ended December 31, 2023 and 2022, there was one customer that represented approximately 17% and
14% of revenues, respectively. Disruption of sales orders or a deterioration of financial condition of its customers would have a negative impact on the
Company’s financial position and results of operations.

The Company manufactures its commercial products in-house, including the Pantheris and Ocelot family of catheters. Certain of the Company’s
product components and sub-assemblies are manufactured by sole suppliers, including internally. Disruption in component or sub-assembly supply from
these manufacturers or from in-house production would have a negative impact on the Company’s financial position and results of operations.

The Company is subject to certain risks, including that its devices may not be approved or cleared for marketing by governmental authorities or be
successfully marketed. There can be no assurance that the Company’s products will achieve widespread adoption in the marketplace, nor can there be any
assurance  that  existing  devices  or  any  future  devices  can  be  developed  or  manufactured  at  an  acceptable  cost  and  with  appropriate  performance
characteristics. The Company is also subject to risks common to companies in the medical device industry, including, but not limited to, new technological
innovations, dependence upon third-party payors to provide adequate coverage and reimbursement, dependence on key personnel and suppliers, protection
of proprietary technology, product liability claims, and compliance with government regulations.

Existing or future devices developed by the Company may require approvals or clearances from the FDA or international regulatory agencies. In
addition, in order to continue the Company’s operations, compliance with various federal and state laws is required. If the Company were denied or delayed
in receiving such approvals or clearances, it may be necessary to adjust operations to align with the Company’s currently approved portfolio. If clearance
for the products in the current portfolio were withdrawn by the FDA, this may have a material adverse impact on the Company.

Disruption  of  our  supply  chain  capabilities  due  to  trade  restrictions,  political  instability,  severe  weather,  natural  disasters,  public  health  crises,
terrorism,  product  recalls,  labor  supply  or  stoppages,  the  financial  or  operational  instability  of  key  suppliers  and  carriers,  government  restrictions  or
measures,  or  other  reasons  could  impair  our  ability  to  distribute  our  products.  The  Company  believes  capacity  issues  and  resource  constraints  and  the
related increased cost pressures and burdens on the hospital systems have had and may continue to have an adverse effect on its ability to generate sales due
to the fluctuating and unpredictable levels of capacity medical providers have to perform procedures that require the use of its products. In addition, the
Company  has  experienced  disruptions  in  its  manufacturing  and  supply  chain,  as  well  as  delays  in  site  initiation  and  patient  enrollment  for  its  clinical
studies. If the Company is unable to successfully complete these or other clinical studies, its business and results of operations could be harmed.

The Company is closely monitoring general economic conditions on global supply chain, manufacturing, and logistics operations. As inflationary
pressures increase, the Company has experienced and further anticipates that its production and operating costs may continue to increase, including costs
and  availability  of  materials  and  labor.  While  the  Company  has  sufficient  inventory  on-hand  to  meet  its  current  production  requirements  and  customer
demand, it has experienced some constraints with respect to the availability of certain materials and extended lead times from certain key suppliers. The
Company has also experienced some delays in shipping products to its customers. Any significant delay or interruption in our supply chain could impair the
Company’s ability to meet the demands of its customers in the future and could harm its business.

We  use  technology  in  substantially  all  aspects  of  our  business  operations,  and  our  ability  to  serve  customers  most  effectively  depends  on  the
reliability of our technology systems. Cybersecurity incidents can include computer viruses, computer denial-of-service attacks, worms, and other malicious
software programs or other attacks, covert introduction of malware to computers and networks, impersonation of authorized users, and efforts to discover
and  exploit  any  design  flaws,  bugs,  security  vulnerabilities  or  security  weaknesses,  as  well  as  intentional  or  unintentional  acts  by  employees  or  other
insiders with access privileges, intentional acts of vandalism by third parties and sabotage.

In  addition,  our  technology  infrastructure  and  systems  are  vulnerable  to  damage  or  interruption  from  natural  disasters,  power  loss  and
telecommunications failures. Any such disruption to our systems, or the technology systems of third parties on which we rely, the failure of these systems to
otherwise  perform  as  anticipated,  or  the  theft,  destruction,  loss,  misappropriation,  or  release  of  sensitive  and/or  confidential  information  or  intellectual
property, could require us to notify affected individuals, federal or state agencies or media outlets of the incident and could result in business disruption,
negative publicity, loss of customers, potential liability, including litigation or other legal actions against us or the imposition of penalties, fines, fees or
liabilities, which may not be covered by our insurance policies, and competitive disadvantage, any or all of which would potentially adversely affect our
customer service, decrease the volume of our business and result in increased costs and lower profits. Moreover, a cybersecurity breach could require us to
devote  significant  management  resources  to  address  the  problems  associated  with  the  breach  and  to  expend  significant  additional  resources  to  upgrade
further the security measures we employ to protect information against cyber-attacks and other wrongful attempts to access such information, which could
result in a disruption of our operations.

While  we  have  invested,  and  continue  to  invest,  in  technology  security  initiatives  and  other  measures  to  prevent  security  breaches  and  cyber
incidents, as well as disaster recovery plans, these initiatives and measures may not be entirely effective to insulate us from technology disruption that could
result in adverse effects on our results of operations.

Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the Company’s best
estimate  of  the  amount  of  probable  credit  losses  in  the  Company’s  existing  accounts  receivable.  The  Company  determines  the  allowance  for  doubtful
accounts  based  upon  an  aging  of  accounts  receivable,  historical  experience,  and  management  judgment.  Accounts  receivable  balances  are  reviewed
individually for collectability. To date, the Company has not experienced significant credit-related losses.

Inventories

Inventories are valued at the lower of cost or net realizable value. Cost is determined using the first-in, first-out method for all inventories. The
Company’s policy is to write down inventory that has expired or become obsolete, inventory that has a cost basis in excess of its expected net realizable
value,  and  inventory  in  excess  of  expected  requirements.  At  each  balance  sheet  date,  management  evaluates  inventories  for  excess  quantities,  and
obsolescence. This evaluation by management includes analysis of historical sales levels by product, projections of future demand, the risk of technological
or  competitive  obsolescence  for  products,  general  market  conditions,  as  well  as  the  feasibility  of  reworking  or  using  excess  or  obsolete  products  or
components in the production or assembly of other products that are not obsolete or for which there are not excess quantities in inventory. To the extent that
management determines there are excess or obsolete inventory, management adjusts the carrying value to estimated net realizable value. When quantities on
hand exceed sales forecasts, a write-down is recorded for such excess inventories along with a corresponding charge to cost of revenues. The estimate of
excess quantities is subjective and primarily dependent on the estimates of future demand for a particular product. Specifically, the future demand is derived
based on our historical experience, from discussion with users of our products and general market conditions. Changes in assumptions of product demand
could have a significant impact on the amount of write-down recorded. Inventory used in clinical trials is expensed at the time of production and recorded
as research and development expense if the inventory is contractually being provided at no cost to the clinical site. The cost of inventories are regularly
reviewed against estimated market value and record a lower of cost or market reserve for inventories that have a cost in excess of estimated market value,
which could have a material impact on the gross margin and inventory balances based on additional write-downs to net realizable value or a benefit from
inventories previously written down.

Property and Equipment

Property  and  equipment  are  recorded  at  cost.  Repairs  and  maintenance  costs  are  expensed  as  incurred.  Depreciation  and  amortization  are
calculated using the straight-line method over the estimated useful lives of the assets of generally three to five years. Depreciation expense includes the
amortization of assets acquired under capital leases and equipment located with the Company’s sales personnel or at customer sites. Equipment held by
customers is comprised of the Lightbox consoles located at customer sites under a lease or placement agreement. Equipment held by field sales personnel is
also comprised of the Lightbox consoles in their possession. The related equipment is reclassified from inventory to the property and equipment account
either upon execution of a lease or placement agreement for customers or upon shipment to a field salesperson. Depreciation expense for equipment held by
customers or field sales personnel is recorded as a component of cost of revenues. Leasehold improvements and assets recorded under capital leases are
amortized using the straight-line method over the shorter of the lease term or estimated useful economic life of the asset.

Impairment of Long-Lived Assets

The Company reviews long-lived assets, including property and equipment, for impairment whenever events or changes in business circumstances
indicate that the carrying amount of the assets may not be fully recoverable. If indicators of impairment exist, an impairment loss would be recognized
when estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount.
Impairment, if any, is measured as the amount by which the carrying amount of the long-lived asset exceeds its fair value. The Company has not recorded
any impairment of long-lived assets since inception through December 31, 2023.

Revenue Recognition

The Company’s revenues are derived from (1) sale of Lightbox consoles, (2) sale of disposables, which consist of catheters and accessories, and
(3)  sale  of  customer  service  contracts  and  maintenance.  The  Company  sells  its  products  directly  to  hospitals  and  medical  centers  as  well  as  through
distributors. The Company accounts for a contract with a customer when there is a legally enforceable contract between the Company and the customer, the
rights  of  the  parties  are  identified,  the  contract  has  commercial  substance,  and  collectability  of  the  contract  consideration  is  probable.  The  Company’s
revenues are measured based on consideration specified in the contract with each customer, net of any sales incentives and taxes collected from customers
that  are  remitted  to  government  authorities.  For  all  sales,  the  Company  uses  either  a  signed  agreement,  a  binding  purchase  order  or  other  written
documentation as evidence of an arrangement. The Company’s revenue recognition policies generally result in revenue recognition at the following points:

1.

2.

3.

Lightbox console sales: Provided all other criteria for revenue recognition have been met, the Company recognizes revenue for Lightbox
console sales directly to end customers when delivery and acceptance occurs, which is defined as receipt by the Company of an executed
form that the installation process is complete. If installation is not required, as is the case with the Lightbox 3, recognition occurs upon
the completion of delivery pursuant to the stated delivery terms.

Sales  of  disposables:  Disposable  revenues  consist  of  sales  of  the  Company’s  catheters  and  accessories  and  are  recognized  when  the
product has shipped, risk of loss and title has passed to the customer and collectability is reasonably assured.

Service  revenue:  Service  contract  revenue  consists  of  preventative  maintenance,  upgrades,  and  service  contracts.  Service  contracts  are
recognized ratably over the term of the service period and maintenance contract revenue is recognized when work is completed. To date,
service revenue has been insignificant.

The Company offers its customers the ability to purchase or lease the Lightbox console. In addition, the Company provides a Lightbox under a
limited commercial evaluation program to allow accounts to install and utilize the Lightbox for a limited trial period. When a Lightbox is placed under a
lease agreement or under a commercial evaluation program, the Company retains title to the equipment and it remains capitalized on its balance sheet under
property and equipment. Depreciation expense on these placed Lightboxes is recorded to cost of revenues on a straight-line basis. The costs to maintain
these placed Lightboxes are charged to cost of revenues as incurred.

The  Company  evaluates  its  lease  and  commercial  evaluation  program  agreements  and  accounts  for  these  contracts  under  the  guidance  in
Accounting  Standards  Codification  (“ASC”)  842,  Leases  and  ASU  No.  2014  09,  Revenue  from  Contracts  with  Customers  (Topic  606).  The  guidance
requires  arrangement  consideration  to  be  allocated  between  a  lease  deliverable  and  a  non-lease  deliverable  based  upon  the  relative  selling-price  of  the
deliverables.

The Company assessed whether the embedded lease is an operating lease or sales-type lease. Based on the Company’s assessment of the guidance
and given that any payments under the lease agreements are dependent upon contingent future sales, it was determined that collectability of the minimum
lease payments is not reasonably predictable. Accordingly, the Company concluded the embedded lease did not meet the criteria of a sales-type lease and
accounts for it as an operating lease. The Company recognizes revenue allocated to the lease as the contingent disposable product purchases are delivered
and are included in revenues within the statement of operations and comprehensive loss.

For  sales  of  disposables  through  distributors,  the  Company  recognizes  revenue  when  control  of  the  product  transfers  from  the  Company  to  the
distributor. The distributors are responsible for all statutory obligations, marketing, sales, training and warranty in their respective territories. The standard
terms and conditions contained in the Company’s distribution agreements do not provide price protection or stock rotation rights to any of its distributors.
In addition, its distributor agreements do not allow the distributor to return or exchange products, and the distributor is obligated to pay the Company upon
invoice regardless of its ability to resell the product.

Cost of Revenues

Cost of revenues consists primarily of manufacturing overhead costs, material costs and direct labor. A significant portion of the Company’s cost
of revenues currently consists of manufacturing overhead costs. These overhead costs include the cost of quality assurance, material procurement, inventory
control, facilities, equipment and operations supervision and management. Cost of revenues also includes depreciation expense for the Lightboxes under
lease,  deployed  with  sales  personnel  and  evaluation  agreements,  product  warranty  costs,  product  written-off  due  to  excess  or  obsolescence,  and  certain
direct costs such as shipping costs.

Product Warranty Costs

The  Company  typically  offers  a  one-year  warranty  on  its  products  commencing  upon  the  transfer  of  title  and  risk  of  loss  to  the  customer.  The
Company accrues for the estimated cost of product warranties upon invoicing its customers, based on historical results. Warranty costs are reflected in the
statement  of  operations  and  comprehensive  loss  as  a  cost  of  revenues.  The  warranty  obligation  is  affected  by  product  failure  rates,  material  usage  and
service delivery costs incurred in correcting a product failure. Should actual product failure rates, material usage or service delivery costs differ from these
estimates,  revisions  to  the  estimated  warranty  liability  would  be  required.  Periodically  the  Company  assesses  the  adequacy  of  its  recorded  warranty
liabilities and adjusts the amounts as necessary. Warranty provisions and claims are summarized as follows (in thousands):

The Company expenses research and development costs as incurred. Research and development expenses include personnel and personnel-related
costs, costs associated with pre-clinical and clinical development activities, and costs for prototype products that are manufactured prior to market approval
for that prototype product, and internal and external costs associated with the Company’s regulatory compliance, including the costs of outside consultants
and  contractors  that  assist  in  the  process  of  submitting  and  maintaining  regulatory  filings,  and  overhead  costs,  including  allocated  facility  and  related
expenses.

Clinical Trials

The Company accrues and expenses costs for its clinical trial activities performed by third parties, including clinical research organizations and
other service providers, based upon estimates of the work completed over the life of the individual study in accordance with associated agreements. The
Company determines these estimates through discussion with internal personnel and outside service providers as to progress or stage of completion of trials
or services pursuant to contracts with clinical research organizations and other service providers and the agreed-upon fee to be paid for such services.

Stock-Based Compensation

Stock-based compensation for the Company includes amortization related to all stock options, restricted stock units (“RSU”), and restricted stock
awards  (“RSA”)  based  on  the  grant-date  estimated  fair  value.  The  fair  value  of  stock  options  is  estimated  on  the  date  of  grant  using  the  Black-Scholes
option  pricing  model  and  recognized  as  expense  on  a  straight-line  basis  over  the  vesting  period  of  the  award.  The  Company  has  not  granted  any  stock
options since 2017. The Company measures the fair value of RSUs and RSAs using the closing stock price of a share of the Company’s common stock on
the  grant  date  and  is  recognized  as  expense  on  a  straight-line  basis  over  the  vesting  period  of  the  award.  As  allowed  under  ASU  No.  2016‑09,
Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, the Company accounts for forfeitures as
they occur.

Foreign Currency

The Company records net gains and losses resulting from foreign exchange transactions as a component of foreign currency exchange losses in
other income (expense), net. During the years ended December 31, 2023 and 2022, the Company recorded a net gain of $12,000 and a net loss of $12,000
of foreign currency exchange, respectively.

Income Taxes

The Company utilizes the liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined
based on differences between financial reporting and tax reporting bases of assets and liabilities and are measured using enacted tax rates and laws that are
expected to be in effect when the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to
the amounts expected to be realized. The Company’s policy is to record interest and penalties on uncertain tax positions as income tax expense when they
occur.  During  the  years  ended  December  31,  2023  and  2022,  the  Company  did  not  recognize  accrued  interest  or  penalties  related  to  unrecognized  tax
benefits.

Net Loss per Share Attributable to Common Stockholders

Basic  net  loss  per  share  attributable  to  common  stockholders  is  computed  by  dividing  the  net  loss  applicable  to  common  stockholders  by  the
weighted average number of shares of common stock outstanding during the period, without consideration for potential dilutive common shares. Diluted
net loss per share attributable to common stockholders is computed by dividing the net loss applicable to common stockholders by the weighted average
number  of  shares  of  common  stock  and  dilutive  potential  shares  of  common  stock  outstanding  during  the  period.  Any  common  stock  shares  subject  to
repurchase are excluded from the calculations as the continued vesting of such shares is contingent upon the holders’ continued service to the Company. As
of December 31, 2023 and 2022, there were no shares subject to repurchase. Since the Company was in a loss position for both periods presented, basic net
loss  per  share  attributable  to  common  stockholders  is  the  same  as  diluted  net  loss  per  share  attributable  to  common  stockholders  as  the  inclusion  of  all
potentially dilutive common shares would have been anti-dilutive.

Net loss per share applicable to common stockholders was determined as follows (in thousands, except per share data):

Segment and Geographical Information

The Company operates and manages its business as one reportable and operating segment. The Company’s chief executive officer, who is the chief
operating decision maker, reviews financial information on an aggregate basis for purposes of allocating resources and evaluating financial performance.
Primarily  all  of  the  Company’s  long-lived  assets,  which  are  comprised  of  property  and  equipment,  are  based  in  the  United  States.  For  the  years  ended
December 31, 2023 and 2022, 90% and 92% of the Company’s revenues were in the United States, based on the shipping location of the external customer.
The remaining revenues for the years ended December 31, 2023 and 2022, were primarily derived in Germany.

Recent Accounting Pronouncements

Recent accounting standards not yet adopted

In December 2023, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2023-09, Income
Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”), which will require the Company to disclose specified additional information
in  its  income  tax  rate  reconciliation  and  provide  additional  information  for  reconciling  items  that  meet  a  quantitative  threshold.  ASU  2023-09  will  also
require the Company to disaggregate its income taxes paid disclosure by federal, state and foreign taxes, if any, with further disaggregation required for
significant  individual  jurisdictions.  The  Company  will  adopt  ASU  2023-09  in  its  first  quarter  of  2025.  ASU  2023-09  allows  for  adoption  using  either  a
prospective or retrospective transition method.

Table of Contents

In  August  2020,  the  FASB  issued  ASU  No.  2020-06,  Debt—Debt  with  Conversion  and  Other  Options  (Subtopic  470-20)  and  Derivatives  and
Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which
among  other  things,  simplifies  the  accounting  models  for  the  allocation  of  proceeds  attributable  to  the  issuance  of  a  convertible  debt  instrument.   As  a
result,  after  adopting  the  ASU’s  guidance,  entities  will  not  separately  present  in  equity  an  embedded  conversion  feature  in  such  debt.  Instead,  they  will
account for a convertible debt instrument wholly as debt, and for convertible preferred stock wholly as preferred stock (i.e., as a single unit of account),
unless (i) a convertible instrument contains features that require bifurcation as a derivative under ASC 815 or (ii) a convertible debt instrument was issued
at a substantial premium. The standard becomes effective for the Company, as a smaller reporting company as defined by the SEC, in the first quarter of
2024 and early adoption is permitted.  This new standard is not expected to have a material impact on the Company’s financial statements.

3. Fair Value Measurements

The Company measures certain financial assets and liabilities at fair value on a recurring basis. Fair value is an exit price, representing the amount
that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-
based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. A three-tier fair
value hierarchy is established as a basis for considering such assumptions and for inputs used in the valuation methodologies in measuring fair value:

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Inputs other than quoted prices included within Level 1 that are observable, either directly or indirectly, such as quoted prices for similar
assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for
substantially the full term of the assets or liabilities.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

As of December 31, 2023 and 2022, the Company’s cash equivalents were all categorized as Level 1 and consisted of money market funds. As of
December 31, 2023 and 2022, there were no financial assets and liabilities categorized as Level 2 or Level 3. There were no transfers between fair value
hierarchy levels during the years ended December 31, 2023 and 2022.

The Company borrowed an additional $10 million on June 15, 2016 under the Loan Agreement.

On  February  14,  2018,  the  Company  and  CRG  further  amended  the  Loan  Agreement  concurrent  with  the  conversion  of  $38  million  of  the
principal amount of the senior secured term loan (plus $3.8 million in back-end fees and prepayment premium applicable thereto) into a newly authorized
Series A convertible preferred stock.

On August 2, 2023, the Company and CRG entered into a Securities Purchase Agreement (“SPA”) pursuant to which the Company issued 1,920
shares of a newly authorized Series E convertible preferred stock (“Series E preferred stock”) in exchange for CRG surrendering for cancellation $1.92
million of outstanding principal and accrued interest of the senior secured term loan under the Loan Agreement (the “Term Loan Agreement”). Each share
of Series E preferred stock has a stated value of $1,000 per share and is convertible into 93 shares of the Company’s common stock at a conversion price of
$10.725 per share, provided that the shares of Series E preferred stock cannot be converted into common stock to the extent the applicable holder would
beneficially  own  in  excess  of  19.99%  of  the  Company’s  outstanding  voting  power,  unless  approved  by  the  Company's  stockholders  in  accordance  with
Nasdaq Listing Rule 5635(b).

The  Company  has  entered  into  several  amendments  to  the  Loan  Agreement  (the  “Amendments”)  with  CRG  since  September  2015.  The
Amendments, among other things: (1) extended the interest-only period through December 31, 2026; (2) extended the period during which the Company
may elect to pay a portion of interest in payment-in-kind (“PIK”), interest payments through December 31, 2026 so long as no Default (as defined in the
Loan Agreement) has occurred and is continuing; (3) permitted the Company to make the entire interest payments in PIK interest payments for through
December 31, 2026 so long as no Default has occurred and is continuing; (4) extended the Stated Maturity Date (as defined in the Loan Agreement) to
December 31, 2025; (5) reduced the minimum liquidity covenant to $3.5 million at all times; (6) eliminated the minimum revenue covenants for all years
(7) changed the date under the on-going stand-alone representation regarding no “Material Adverse Change” to December 31, 2020; (8) amended the on-
going stand-alone representation and stand-alone Event of Default (as defined in the Loan Agreement) regarding Material Adverse Change such that any
adverse change in or effect upon the revenue of the Company and its subsidiaries due to the outbreak of COVID-19 will not constitute a Material Adverse
Change; (9) provided CRG with board observer rights and (10) provide that the board observer may be appointed or removed by written notice from the
Majority Lenders (as defined in the Loan Agreement).

On  January  26,  2024,  the  Company  entered  into  Amendment  No.  7  to  the  Loan  Agreement  with  CRG,  which  reduces  the  minimum  liquidity
requirement of the Loan Agreement from $3.5 million to $1.0 million until April 1, 2024. Thereafter, the Company will be subject to the minimum liquidity
requirement of $3.5 million.

On March 5, 2024, the Company entered into Amendment No. 9 to the Loan Agreement with CRG, which (1) extended the interest-only period
through December 31, 2026; (2) extended the period during which the Company may elect to pay a portion of interest in payment-in-kind (“PIK”), interest
payments through December 31, 2026 so long as no Default (as defined in the Loan Agreement) has occurred and is continuing; (3) permitted the Company
to make the entire interest payments in PIK interest payments for through December 31, 2026 so long as no Default has occurred and is continuing; and (4)
permit the payment of dividends on the preferred stock issued or issuable to the Purchaser, as defined in Note 14. Refer therein for details.

Under the amended Loan Agreement, no cash payments for either principal or interest are required until the first quarter of 2024. The interest will
be accrued and included in the debt balance based (to the extent not paid) on principal amounts outstanding at the beginning of the quarter at an interest rate
of 12.5%. Beginning in the first quarter of 2024, the Company will be required to make quarterly principal payments (in addition to the interest) of $1.6
million with total principal payments of $6.5 million in 2024 and $6.5 million in 2025. The maturity date of the Loan (as defined in the Loan Agreement) is
December 31, 2025.

The  Company  may  voluntarily  prepay  the  borrowings  in  full,  with  a  prepayment  premium  beginning  at  5.0%  and  declining  by  1.0%  annually
thereafter, with no premium being payable if prepayment occurs after seven and half years of the loan. Each tranche of borrowing required the payment, on
the borrowing date, of a financing fee equal to 1.5% of the borrowed loan principal, which is recorded as a discount to the debt. In addition, a facility fee
equal to 15.0% of the amounts borrowed plus any PIK is to be payable at the end of the term or when the borrowings are repaid in full. A long-term liability
is being accreted using the effective interest method for the facility fee over the term of the Loan Agreement with a corresponding discount to the debt. The
borrowings are collateralized by a security interest in substantially all of the Company’s assets.

The Loan Agreement requires that the Company adheres to certain affirmative and negative covenants, including financial reporting requirements,
certain  minimum  financial  covenants  for  pre-specified  liquidity  and  a  prohibition  against  the  incurrence  of  indebtedness,  or  creation  of  additional  liens,
other than as specifically permitted by the terms of the Loan Agreement. In particular, the covenants of the amended Loan Agreement included a covenant
that the Company maintain a minimum of $3.5 million of cash and certain cash equivalents. The minimum liquidity requirement was temporarily reduced
to $1.0 million until April 1, 2024. In addition, the Loan Agreement prohibits the payment of cash dividends on the Company’s capital stock and also places
restrictions on mergers, sales of assets, investments, incurrence of liens, incurrence of indebtedness and transactions with affiliates. CRG may accelerate the
payment terms of the Loan Agreement upon the occurrence of certain “Events of Default” set forth therein, which include the failure of the Company to
make timely payments of amounts due under the Loan Agreement, the failure of the Company to adhere to the covenants set forth in the Loan Agreement,
the insolvency of the Company or upon the occurrence of a “Material Adverse Change” thereunder.

As of December 31, 2023, the Company was in compliance with all applicable covenants under the Loan Agreement.

In connection with drawdowns under the Loan Agreement, the Company recorded aggregate debt discounts of $1.3 million as contra-debt. The
debt discounts are being amortized as non-cash interest expense using the effective interest method over the term of the Loan Agreement. As of December
31, 2023 and 2022, the balance of the aggregate debt discount was approximately $166,000 and $249,000, respectively. The Company’s interest expense
associated with the amortization of debt discount was approximately $83,000 during each of the years ended December 31, 2023 and 2022. The Company
incurred total interest expense of approximately $2.0 million and $1.9 million during the years ended December 31, 2023 and 2022, respectively. 

While,  as  of  the  date  hereof,  CRG  has  not  purported  that  an  Event  of  Default  has  resulted  due  to  a  Material  Adverse  Change  (those  terms  as
defined in the Loan Agreement), due to the substantial doubt about the Company’s ability to continue operating as a going concern, the entire outstanding
amount of borrowings under the Loan Agreement and associated aggregate debt discount at December 31, 2023 were classified as current in these financial
statements.

8. Leases

The  Company’s  operating  lease  obligations  primarily  consist  of  leased  office,  laboratory,  and  manufacturing  space  under  a  non-cancelable
operating lease. In addition to the minimum future lease commitments presented below, the lease requires the Company to pay property taxes, insurance,
maintenance, and repair costs. The lease includes a rent holiday concession and escalation clauses for increased rent over the lease term. Rent expense is
recognized using the straight-line method over the term of the lease.

The  lease  will  expire  on  November  30,  2024.  The  Company  is  obligated  to  pay  approximately  $5.8  million  in  base  rent  payments  through

November 2024, beginning on December 1, 2019. The weighted average remaining lease term as of December 31, 2023 is 0.9 years.

On March 6, 2024, the Company entered into an amendment to the lease which extended the lease term for a period of one year, subsequent to the
original expiration of November 30, 2024. As amended, the lease will expire on November 30, 2025. Under the terms of the amendment, the Company will
be  obligated  to  pay  approximately  $1.3  million  in  base  rent  payments  through  November  2025,  beginning  on  December  1,  2024.  This  amendment  also
provides an optional one year extension of the lease following the end of the current term, as amended.

The operating lease was included on the balance sheet at the present value of the future base payments discounted at a 6.5% discount rate using the
rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term and amount equal to the lease payments in a
similar economic environment as the lease does provide an implicit rate.

The  Company’s  operating  lease  expense,  excluding  variable  maintenance  fees  and  other  expenses  on  a  monthly  basis,  was  approximately
$105,000. Rent expense for each of the years ended December 31, 2023 and 2022 was approximately $1.3 million. The Company’s variable expenses for
the years ended December 31, 2023 and 2022 was approximately $0.4 million and $0.3 million, respectively. Operating right-of-use asset amortization was
approximately $1.1 million for each of the years ended December 31, 2023 and 2022. Due to payments being made in excess of operating lease expense
recognized, the Company recorded approximately $13,000 and $65,000 as prepaid rent included in other assets on the balance sheet as of December 31,
2023 and 2022, respectively.

Purchase obligations consist of agreements to purchase goods and services entered into in the ordinary course of business. The Company had non-
cancelable commitments to suppliers for purchases totaling approximately $0.5 million as of December 31, 2023. The majority of this amount is related to
commitments to purchase inventory components and services related to the manufacturing of inventory.

Indemnification

In the normal course of business, the Company enters into contracts and agreements that contain a variety of representations and warranties and
may provide for indemnification of the counterparty. The Company’s exposure under these agreements is unknown because it involves claims that may be
made against it in the future but have not yet been made. To date, the Company has not been subject to any claims or been required to defend any action
related to its indemnification obligations.

The Company indemnifies each of its directors and officers for certain events or occurrences, subject to certain limits, while the director is or was
serving at the Company’s request in such capacity, as permitted under Delaware law and in accordance with its certificate of incorporation and bylaws. The
term of the indemnification period lasts as long as a director may be subject to any proceeding arising out of acts or omissions of such director in such
capacity. The maximum amount of potential future indemnification is unlimited; however, the Company currently holds director liability insurance. This
insurance  allows  the  transfer  of  risk  associated  with  the  Company’s  exposure  and  may  enable  it  to  recover  a  portion  of  any  future  amounts  paid.  The
Company believes that the fair value of these indemnification obligations is minimal. Accordingly, it has not recognized any liabilities relating to these
obligations for any period presented.

Legal Proceedings

The  Company  is  not  currently  involved  in  any  pending  legal  proceedings  that  it  believes  could  have  a  material  adverse  effect  on  our  financial
condition, results of operations or cash flows. From time to time, the Company may be involved in legal proceedings or investigations, which could harm
our reputation, business and financial condition and divert the attention of our management from the operation of our business.

10. Stockholders’ Equity

Convertible Preferred Stock

As of December 31, 2023, the Company’s certificate of incorporation, as amended and restated, authorizes the Company to issue up to 5,000,000
shares of convertible preferred stock with $0.001 par value per share. As of December 31, 2023 and 2022, 62,881 and 60,961 shares, respectively, were
issued and outstanding.

Series A Convertible Preferred Stock

The holders of Series A preferred stock are entitled to receive annual accruing dividends at a rate of 8%, payable in additional shares of Series A
preferred stock or cash, at the Company’s option. The shares of Series A preferred stock have a liquidation preference of $1,000 per share and carry no
voting rights. During the year ended December 31, 2022, 4,510 of additional shares were issued to CRG as payment of dividends. As of December 31, 2023
and  2022,  60,876  and  60,876  shares  of  Series  A  preferred  stock  were  outstanding,  respectively,  which  are  currently  convertible  into  shares  of  the
Company’s common stock at $6,000 per share. The Series A preferred stock accrued no dividends during the year ended December 31, 2023 and accrued
additional dividends of approximately $4.5 million during the year ended December 31, 2022.

On  September  29,  2023,  the  Company  entered  into  a  waiver  agreement  (the  “Waiver  Agreement”)  with  CRG,  who  hold  all  of  the  outstanding
shares of the Company’s Series A preferred stock. Pursuant to the Waiver Agreement, CRG waived their rights to receive the Series A preferred dividend
for the year ending December 31, 2023. Such waived preferred dividends are not cumulative or accrued. Consequently, there were no Series A preferred
stock dividends recorded during the year ended December 31, 2023.

Series B Convertible Preferred Stock

The Series B preferred stock has a liquidation preference of $0.001 per share, full ratchet price based anti-dilution protection, has no voting rights
and is subject to certain ownership limitations. The Series B preferred stock is immediately convertible at the option of the holder, has no stated maturity,
and does not pay regularly stated dividends or interest. As of December 31, 2023 and 2022, 85 shares of Series B preferred stock remained outstanding,
which are currently convertible into shares of the Company’s common stock at $5.732 per share.

Series D Convertible Preferred Stock

On January 14, 2022, the Company entered into a security purchase agreement with several institutional investors, pursuant to which the Company
agreed  to  sell  and  issue,  in  a  registered  direct  offering  (“January  2022  Offering”),  an  aggregate  of  7,600  shares  of  the  Company’s  Series  D  convertible
preferred stock, par value $0.001 per share at an offering price of $1,000 per share. Concurrently, the Company agreed to issue to these investors warrants
to purchase up to an aggregate of 53,833 shares of the Company’s common stock (the “Common Warrants”).

The shares of Series D preferred stock had a stated value of $1,000 per share and were convertible into an aggregate of 63,333 shares of common
stock at a conversion price of $120.00 per share. During the year ended December 31, 2022, all 7,600 shares of Series D preferred stock were converted
into a total of 63,333 shares of common stock. There are no shares of Series D preferred stock outstanding as of December 31, 2023.

At  the  time  of  issuance,  the  Company  evaluated  the  classification  of  the  Series  D  preferred  stock  and  determined  equity  classification  was
appropriate due to no mandatory or contingently redeemable redemption features. The warrants issued to the investors were considered freestanding equity
classified instruments. The Company first allocated gross proceeds from the registered direct offering between the preferred stock and the warrants issued
to investors using a relative fair value approach, resulting in an initial allocation to each instrument of $4.0 million and $3.6 million, respectively. On the
issuance date, the Company estimated the fair value of the Common Warrants issued to investors and warrants issued to the placement agent designees
using a Black-Scholes option pricing model using the following assumptions: (i) contractual term of 5.5 years, (ii) expected volatility rate of 136.61%, (iii)
risk-free interest rate of 1.51%, (iv) expected dividend rate of 0%, and (v) closing price of the Company’s common stock of the day immediately preceding
the registered direct offering. The fair value of preferred stock was estimated based upon equivalent common shares that preferred stock could have been
converted into at the closing price of the day immediately preceding the purchase date.

Table of Contents

The embedded conversion feature was evaluated and bifurcation from the preferred stock equity host was not considered necessary. The issuance
of  the  Series  D  convertible  preferred  stock  generated  a  beneficial  conversion  feature  (“BCF”)  which  arose  as  the  equity  security  was  issued  with  an
embedded conversion option that is beneficial to the investor or in the money at inception because the conversion option has an effective conversion price
that  is  less  than  the  market  price  of  the  underlying  stock  at  the  commitment  date.  The  Company  recorded  the  BCF  as  a  discount  to  the  preferred  stock
resulting in the amount of $5.1 million based on the intrinsic value of the beneficial conversion. As the preferred stock was immediately convertible into
common stock subject to the consummation of the reverse stock split on March 14, 2022, a deemed dividend related to the discount associated with the
beneficial conversion feature was recorded on that date. This one-time, non-cash charge impacted net loss applicable to common stockholders and net loss
per share attributable to common stockholders for the year ended December 31, 2022.

Series E Convertible Preferred Stock

On August 2, 2023, the Company entered into a Series E Purchase Agreement with CRG, pursuant to which it agreed to surrender $1.92 million of
the outstanding principal and accrued interest of its senior secured term loan into Series E preferred stock. Each share of Series E preferred stock has a
stated value of $1,000 per share and is convertible into 93 shares of the Company’s common stock at a conversion price of $10.725 per share. The Series E
preferred stock is initially convertible into 178,560 shares of common stock subject to certain limitations contained in the Series E Purchase Agreement.
Shares of Series E preferred stock cannot be converted into common stock to the extent the applicable holder would beneficially own in excess of 19.99%
of the Company’s outstanding voting power, unless approved by the Company's stockholders in accordance with Nasdaq Listing Rule 5635(b). Under the
terms of the Series E Purchase Agreement, the holders of Series E preferred stock are entitled to receive annual accruing dividends at a rate of 8%, payable
in additional shares of Series E preferred stock or cash, at the Company’s option. The shares of Series E preferred stock have full voting rights, on an as-
converted basis, subject to certain limitations. The Series E preferred stock rank senior to all other classes and series of the Company’s equity in terms of
repayment and certain other rights. As of December 31, 2023, 1,920 shares of Series E preferred stock were outstanding.

On September 29, 2023, the Company entered into the Waiver Agreement with CRG, who hold all of the outstanding shares of the Company’s
Series  E  preferred  stock.  Pursuant  to  the  Waiver  Agreement,  CRG  waived  their  rights  to  receive  the  Series  E  preferred  dividend  for  the  year  ending
December  31,  2023.  Such  waived  preferred  dividends  are  not  cumulative  or  accrued.  Consequently,  there  were  no  Series  E  preferred  stock  dividends
recorded during the year ending December 31, 2023.

Common Stock

At December 31, 2023, the Company’s certificate of incorporation, as amended and restated, authorizes the Company to issue up to 100,000,000

shares of common stock with $0.001 par value per share, of which 1,279,928 shares were issued and outstanding.

Funded  Warrants”).  The  August  2022  Pre-Funded  Warrants  have  an  exercise  price  of  $0.0001  per  share,  are  immediately  exercisable,  and  have  no
expiration date. During the year ended December 31, 2022, 52,268 of shares of RD Pre-Funded Warrants were exercised into the equivalent number of the
Company’s common stock. During the year ended December 31, 2023, all the remaining 91,324 Private Placement Pre-Funded Warrants were exercised.
Consequently, no August 2022 Pre-Funded Warrants remain outstanding as of December 31, 2023.

Also in the August 2022 Offering, the Company issued Series A preferred investment options to purchase up to 190,259 additional shares of the
Company’s  common  stock  and  Series  B  preferred  investment  options  to  purchase  up  to  190,259  additional  shares  of  the  Company’s  common  stock,
collectively  referred  to  as  Preferred  Investment  Options.  The  Series  A  preferred  investment  options  have  an  exercise  price  of  $22.53  per  share,  are
immediately  exercisable,  and  will  expire  five  and  one-half  years  from  the  date  of  issuance,  or  February  8,  2028,  and  the  Series  B  preferred  investment
options have an exercise price of $22.53 per share, are immediately exercisable, and will expire two years from the date of issuance, or August 8, 2024.

The Company also issued to the placement agent of the August 2022 Offering preferred investment options to purchase up to 11,416 shares of
common stock (the “Placement Agent Preferred Investment Options”). The Placement Agent Preferred Investment Options are subject to the same terms as
the Preferred Investment Options, except that the Placement Agent Preferred Investment Options have an exercise price of $32.85 per share and a term of
five years from the commencement of the sales pursuant to the August 2022 Offering, or August 3, 2027.

The exercise price and the number of shares of common stock issuable upon exercise of each Common Warrants, Preferred Investment Options,
and Placement Agent Preferred Investment Options are subject to appropriate adjustments in the event of certain stock dividends and distributions, stock
splits,  stock  combinations,  reclassifications  or  similar  events  affecting  the  common  stock.  In  addition,  in  certain  circumstances,  upon  a  fundamental
transaction,  a  holder  of  Common  Warrants,  Preferred  Investment  Options,  or  Placement  Agent  Preferred  Investment  Options  will  be  entitled  to  receive,
upon exercise, the kind and amount of securities, cash or other property that such holder would have received had they exercised the Common Warrants,
Preferred Investment Options, or Placement Agent Preferred Investment Options immediately prior to the fundamental transaction.

The Common Warrants, Preferred Investment Options, and Placement Agent Preferred Investment Options can be exercised at the option of the
holders  at  any  time  after  they  become  exercisable  provided  that  shares  of  the  Common  Warrants,  Preferred  Investment  Options,  or  Placement  Agent
Preferred Investment Options cannot be exercised into common stock if the applicable holder would beneficially own in excess of 4.99% (or, upon election
by such holder prior to the issuance of any shares of Common Warrants, Preferred Investment Options, or Placement Agent Preferred Investment Options,
9.99%)  of  the  Company’s  outstanding  common  stock  immediately  after  giving  effect  to  the  exercise.  A  holder  of  the  Common  Warrants,  Preferred
Investment Options or Placement Agent Preferred Investment Options may, upon notice to the Company, increase or decrease such beneficial ownership
limitation, but not in excess of 9.99%.

In the event of a fundamental transaction in which the holders of our voting securities immediately prior to such fundamental transaction will not,
following such fundamental transaction, directly or indirectly own more than 50% of the voting securities of the surviving entity or successor entity, and in
which the Company is not the successor entity or does not continue as a reporting issuer under the Exchange Act, then, at the request of the holder, the
Company  or  the  successor  entity  shall  purchase  the  unexercised  portion  of  the  Common  Warrants,  Preferred  Investment  Options,  and  Placement  Agent
Preferred Investment Options from the holder by paying to the holder an amount, in cash, equal to the fair value of the remaining unexercised portion of the
Common Warrants, Preferred Investment Options, and Placement Agent Preferred Investment Options on the date of such fundamental transaction, subject
to certain limitations in the event of a fundamental transaction not within our control.

As  of  December  31,  2023  and  2022,  warrants  and  preferred  investment  options  to  purchase  an  aggregate  of  456,096  and  550,343  shares  of
common stock were outstanding, respectively, all of which were classified within the equity section of the respective balance sheets. During the year ended
December 31, 2023 the 8,768,395 warrants shares issued in connection with the November 2018 financing expired unexercised.

11. Stock-Based Compensation

Stock Plans

In  January  2015,  the  Board  of  Directors  adopted  and  the  Company’s  stockholders  approved  the  2015  Equity  Incentive  Plan  (“2015  Plan”).  On
October 14, 2022, the Company’s stockholders approved an additional 116,667 shares of common stock for issuance under the 2015 Plan. The following
year on December 22, 2023, the Company’s stockholders approved an additional 300,000 shares of common stock for issuance under the 2015 Plan, which
was later registered in an S-8 registration statement filed on January 10, 2024. The 2015 Plan provides for the grant of incentive stock options (“ISOs”) to
employees and for the grant of non-statutory stock options (“NSOs”), restricted stock, restricted stock awards (“RSAs”), restricted stock units (“RSUs”),
stock appreciation rights, performance units and performance shares to employees, directors and consultants. As of December 31, 2023, 24,890 shares were
available for grant under the 2015 Plan.

Pursuant to the 2015 Plan, ISOs and NSOs may be granted with exercise prices at not less than 100% of the fair value of the common stock on the
date of grant and the exercise price of ISOs granted to a stockholder, who, at the time of grant, owns stock representing more than 10% of the voting power
of  all  classes  of  the  stock  of  the  Company,  shall  be  not  less  than  110%  of  the  fair  market  value  per  share  of  common  stock  on  the  date  of  grant.  The
Company’s Board of Directors determines the vesting schedule of the options.

There were no options granted, exercised, expired or forfeited during the years ended December 31, 2023 and 2022. For the years ended December
31, 2023 and 2022, there was no stock-based compensation expense recognized associated with stock options vesting. As of December 31, 2023, there is no
remaining  unamortized  stock-based  compensation  expense  associated  with  unvested  stock  options.  Because  of  the  Company’s  net  operating  losses,  the
Company did not realize any tax benefits from share-based payment arrangements for the years ended December 31, 2023 and 2022.

The Company’s RSUs and RSAs generally vest annually over two years in equal increments. RSAs and RSUs largely contain the same contractual
terms except RSAs have the ability to vote along with common holders as an RSA is considered an outstanding security at the time of grant, subject to
certain vesting and other restrictions. The Company measures the fair value of RSAs using the closing stock price of a share of the Company’s common
stock on the grant date and is recognized as expense on a straight-line basis over the vesting period of the award. As of December 31, 2022, the Company
had 28 shares of RSUs and no shares of RSAs outstanding. A summary of all RSA and RSU activity is presented below:

As of December 31, 2023, there was $0.8 million of remaining unamortized stock-based compensation expense associated with RSAs, which will
be expensed over a weighted average remaining service period of 1.0 year. The outstanding non-vested and expected to vest RSAs at December 31, 2023
have  an  aggregate  fair  value  of  approximately  $0.2  million.  The  Company  used  the  closing  market  price  of  $2.71  per  share  at  December  29,  2023  to
determine the aggregate fair value for the RSAs outstanding at that date. For the years ended December 31, 2023 and 2022, the fair value of the RSAs and
RSUs vested was approximately $42,000 and $14,000, respectively. For the years ended December 31, 2023 and 2022, stock-based compensation expense
recognized associated with the vesting of RSAs and RSUs was approximately $0.9 million and $0.1 million, respectively.

Total  noncash  stock-based  compensation  expense  relating  to  the  Company’s  RSAs  and  RSUs  recognized,  before  taxes,  during  the  years  ended

As  of  December  31,  2023,  the  Company  had  approximately  $355.7  million  of  federal  and  $217.1  million  of  state  net  operating  loss  carryforwards
available  to  offset  future  taxable  income.  If  not  utilized,  the  federal  and  state  net  operating  loss  carryforwards  begin  to  expire  in  2027  and  2024,
respectively. Out of the Federal net operating loss carryforwards, $98.2 million were generated post December 31, 2017 and have no expiration.

As  of  December  31,  2023,  the  Company  also  had  approximately  $4.5  million  and  $4.4  million  of  research  and  development  tax  credit
carryforwards  available  to  reduce  future  taxable  income,  if  any,  for  both  federal  and  California  purposes,  respectively.  The  federal  credit  carryforwards
expire beginning in 2027, and the California research credits do not expire and may be carried forward indefinitely.

The Company's ability to utilize the net operating loss and tax credit carryforwards in the future may be subject to substantial restrictions in the
event of past or future ownership changes as defined in Section 382 of the Internal Revenue Code and similar state tax laws. In the event the Company
should experience an ownership change, as defined, utilization of the Company's net operating loss carryforwards and tax credits could be limited.

The  Company  evaluates  tax  positions  for  recognition  using  a  more-likely-than-not  recognition  threshold,  and  those  tax  positions  eligible  for
recognition are measured as the largest amount of tax benefit that is greater than 50% likely of being realized upon the effective settlement with a taxing
authority that has full knowledge of all relevant information.

A reconciliation of the beginning and ending amount of the gross recognized tax benefit is as follows (in thousands):

As of December 31, 2023, all unrecognized tax benefits would be subject to a full valuation allowance, if recognized, and would not affect the

Company’s tax rate.

The  Company  does  not  anticipate  that  the  total  amounts  of  unrecognized  tax  benefits  will  significantly  increase  or  decrease  in  the  next  twelve

months.

The Company's policy is to include interest and penalties related to unrecognized tax benefits within its provision for income taxes. Due to the
Company's net operating loss position, the Company has not recorded an accrual for interest or penalties related to uncertain tax positions for the years
ended December 31, 2023 and 2022.

13. 401(k) Plan

The Company has a qualified retirement plan under section 401(k) of the Internal Revenue Code (“IRC”) under which participants may contribute
up  to  99%  of  their  eligible  compensation,  subject  to  maximum  deferral  limits  specified  by  the  IRC.  The  Company  may  make  a  discretionary  matching
contribution to the 401(k) plan, and may make a discretionary employer contribution to each eligible employee each year. To date, the Company has made
no contributions to the 401(k) plan.

14. Subsequent Events

Restricted Stock Awards Granted

On January 11, 2024, the Company granted a total of 76,791 shares of RSAs to the Company’s non-employee directors. This granting of RSAs
represents the 2023 annual equity grants pursuant to the Company’s Outside Director Compensation Policy which entitles each non-employee director to
receive equity compensation having a grant date fair value equal to $75,000 annually. These RSAs fully vest one year from the grant date. The Company
measured  the  fair  value  of  RSAs  using  the  closing  stock  price  of  a  share  of  the  Company’s  common  stock  of  $2.93  on  the  day  of  grant.  The  resulting
expense will be recognized on a straight-line basis over the vesting period of the awards.

Retention Bonus Payments and resulting Restricted Stock Award Grants

In satisfaction of certain retention bonus payment obligations for a number of employees which include among others, Jeffrey M. Soinski, Chief
Executive  Officer  and  Himanshu  Patel,  Chief  Technology  Officer,  the  Company  paid  a  total  of  $0.9  million  in  the  form  of  RSAs  on  January  16,  2024.
Pursuant to the retention bonus terms as approved by the Compensation Committee (the “Committee”) of the Board of Directors on March 9, 2021, the
Company may elect to pay these incentive payments in either cash or equity, or a combination of both. On January 11, 2024, the Committee approved the
aforementioned payment in the form of RSAs.

Specifically, the Company granted a total of 317,314 shares of RSAs which vested immediately upon grant. To satisfy all associated income and
other  statutory  tax  obligations  on  behalf  of  the  employees,  the  Company  employed  a  withhold-to-cover  payment  method.  Consequently,  123,285  RSA
shares were withheld resulting in a net issuance of common shares to employees totaling 194,029. The Company measured the fair value of RSAs using the
closing stock price of a share of the Company’s common stock of $2.70 on the day of grant. The resulting expense will be offset against the reversal of the
associated accrued compensation liability thereby resulting in little to no income statement effect during the quarter ended March 31, 2024.

Strategic Partnership

On March 4, 2024, the Company entered into a License and Distribution Agreement (the “License Agreement”) with Zylox-Tonbridge effective as
of  the  Initial  Closing  (defined  below),  pursuant  to  which  the  Company  will  license  and  distribute  certain  of  the  Company’s  products  (including
consumables)  in  the  Greater  China  region,  including  mainland  China,  Hong  Kong,  Macao,  and  Taiwan  (the  “Territory”).  Zylox-Tonbridge  will  lead  all
regulatory activities for the registration of the Avinger products in the Territory. Avinger will also license its intellectual property and know-how related to
Avinger  products  to  Zylox-Tonbridge  so  that  Zylox-Tonbridge  can  manufacture  the  localized  products  in  the  Territory.  Avinger  will  supply  Avinger
products  to  Zylox-Tonbridge  until  Zylox-Tonbridge’s  manufacturing  capability  has  been  established  and  Zylox-Tonbridge  has  obtained  the  regulatory
approval  of  the  localized  products  manufactured  by  Zylox-Tonbridge.  All  sales  of  Avinger  products  locally  manufactured  by  Zylox-Tonbridge  with
regulatory approval by the regulatory authorities in the Territory and commercialized in the Territory will be royalty bearing to Avinger at a rate from a
mid-single to high-single digit percentage depending on the amount of gross revenue as defined in the License Agreement, with certain increases depending
on the amount of product gross margin. The License Agreement has an initial term of 20 years, which shall be further automatically extended for additional
20-year terms, subject to certain conditions. The License Agreement may not be terminated by either party, other than for certain uncured material breaches
or the other party’s insolvency.

In connection with the License Agreement, on March 4, 2024, the Company and Zylox-Tonbridge also entered into a Strategic Cooperation and
Framework Agreement in conjunction with the Initial Closing (the “Collaboration Agreement” and, together with the License Agreement, the “Strategic
Collaboration”),  which  provides  the  opportunity  for  the  Company  to  access  certain  Zylox-Tonbridge  peripheral  vascular  products  for  distribution  in  the
U.S. and Germany. The agreement also provides the option for Avinger to source finished goods inventory from Zylox-Tonbridge following registration of
Zylox-Tonbridge’s manufacturing facility with the FDA.

Financing Agreements

On  March  4,  2024,  in  connection  with  the  Strategic  Collaboration,  the  Company  and  Zylox-Tonbridge  Medical  Limited,  a  wholly-owned
subsidiary  of  Zylox-Tonbridge  (the  “Purchaser”),  entered  into  a  Securities  Purchase  Agreement  (the  “Purchase  Agreement”),  pursuant  to  which  the
Purchaser agreed to purchase, in two tranches, up to an aggregate of $15 million in shares of the Company’s common stock, par value $0.001 per share (the
“Common Stock”), and shares of two new series of the Company’s preferred stock (the “Private Placement”). On March 5, 2024, (the “Initial Closing”), the
Company issued to the Purchaser 75,327 shares of the Common Stock at a purchase price per share of $3.664 (the “Purchase Price”), and 7,224 shares of a
newly authorized Series F convertible preferred stock, par value $0.001 per share (the “Series F Preferred Stock”), at a purchase price per share of $1,000,
for an aggregate purchase price of $7.5 million.

Each share of Series F Preferred Stock has a stated value of $1,000 and is initially convertible into approximately 273 shares of Common Stock at
a conversion price equal to the Purchase Price, subject to the terms of the Certificate of Designation of Preferences, Rights, and Limitations of the Series F
Preferred Stock (the “Series F Certificate of Designation”).

Upon completion of the following as mutually agreed upon by the Company and the Purchaser: (i) the successful registration and listing under 21
CFR part 807 with the FDA of the Purchaser and one of its designated affiliates to manufacture Avinger’s products, and (ii) the Company achieving an
aggregate of $10 million in gross revenue within any four consecutive fiscal quarters after the Initial Closing, excluding any gross revenue achieved by
Avinger under the License Agreement discussed above (together, the “Milestones”), the Purchaser will invest an additional $7.5 million (the “Milestone
Closing”) to purchase shares of the Company new Series G convertible preferred stock, par value $0.001 per share (the “Series G Preferred Stock”). Each
share of Series G Preferred Stock will have a stated value of $1,000 and will be convertible into shares of Common Stock at a conversion price of equal to
the  lowest  of  (x)  the  Purchase  Price,  (y)  the  closing  price  of  the  Common  Stock  on  the  date  immediately  preceding  the  Milestone  Closing,  and  (z)  the
average of the closing price for the last five trading days preceding the Milestone Closing, provided that the conversion price will be no less than $0.20.

The Company’s obligations to (i) accept conversion of the shares of Series F Preferred Stock in excess of 19.99% of the Company’s outstanding
common stock as of the date of the Purchase Agreement and (ii) issue and sell shares of Series G Preferred Stock upon completion of the Milestones are
each  subject  to  receipt  of  the  approval  of  the  Company’s  stockholders  as  is  necessary  under  the  rules  and  regulations  of  Nasdaq  (including,  without

In  connection  with  the  Strategic  Collaboration  and  the  Private  Placement,  on  March  5,  2024,  the  Company  entered  into  a  Securities  Purchase
Agreement (the “A-1 Securities Purchase Agreement”) with CRG to exchange all outstanding shares of its Series A preferred stock for 10,000 shares of
Series  A-1  preferred  stock  (the  “Exchange”).  Among  other  things,  the  shares  of  Series  A-1  preferred  stock:  (i)  are  convertible  into  an  aggregate  of
approximately 2,729,257 shares of common stock at a conversion price equal to the Purchase Price, (ii) do not accrue or pay dividends payable solely on
the Series A-1 preferred stock, (iii) will have no liquidation preference and (iv) will be junior in rank to shares of the Company’s Series E preferred stock,
Series F preferred stock and Series G preferred stock.

CRG Loan Amendment

In  connection  with  the  Strategic  Collaboration  and  the  Private  Placement,  the  Company  also  agreed  to  enter  into  Amendment  No.  9  to  Loan

Agreement effective as of the Initial Closing (the “Amendment”) with CRG, which amends the Loan Agreement to, among other things:

-
-
-

extend the interest-only period through December 31, 2026;
provide that interest payable through December 31, 2026 may be payable in kind rather than in cash; and
permit the payment of dividends on the preferred stock issued or issuable to the Purchaser.

Lease Extension

On March 6, 2024, the Company entered into an amendment to the lease which extended the lease term for a period of one year, subsequent to the
original expiration of November 30, 2024. As amended, the lease will expire on November 30, 2025. Under the terms of the amendment, the Company will
be  obligated  to  pay  approximately  $1.3  million  in  base  rent  payments  through  November  2025,  beginning  on  December  1,  2024.  This  amendment  also
provides an optional one year extension of the lease following the end of the current term, as amended.

INCENTIVE COMPENSATION RECOVERY POLICY

Exhibit 97

1.

Introduction.

The Board of Directors of Avinger, Inc. (the “Company”) believes that it is in the best interests of the Company and its shareholders to create and maintain
a culture that emphasizes integrity and accountability and that reinforces the Company's compensation philosophy. The Board has therefore adopted this
policy, which provides for the recovery of erroneously awarded incentive compensation in the event that the Company is required to prepare an accounting
restatement due to material noncompliance of the Company with any financial reporting requirements under the federal securities laws (the “Policy”). This
Policy is designed to comply with Section 10D of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), related rules and the listing
standards of Nasdaq Stock Market or any other securities exchange on which the Company’s shares are listed in the future.

2. Administration.

This  Policy  shall  be  administered  by  the  Board  or,  if  so  designated  by  the  Board,  the  Compensation  Committee  (the  “Committee”),  in  which  case,  all
references  herein  to  the  Board  shall  be  deemed  references  to  the  Committee.  Any  determinations  made  by  the  Board  shall  be  final  and  binding  on  all
affected individuals.

3. Covered Executives.

Unless and until the Board determines otherwise, for purposes of this Policy, the term “Covered Executive” means a current or former employee who is or
was  identified  by  the  Company  as  the  Company’s  president,  principal  financial  officer,  principal  accounting  officer  (or  if  there  is  no  such  accounting
officer, the controller), any vice-president of the Company in charge of a principal business unit, division, or function (such as sales, administration, or
finance), any other officer who performs a policy-making function, or any other person (including any executive officer of the Company’s subsidiaries or
affiliates) who performs similar policy-making functions for the Company. “Policy-making function” is not intended to include policy-making functions
that  are  not  significant.  “Covered  Executives”  will  include,  at  minimum,  the  executive  officers  identified  by  the  Company  pursuant  to  Item  401(b)  of
Regulation S-K of the Exchange Act.

This Policy covers Incentive Compensation received by a person after beginning service as a Covered Executive and who served as a Covered Executive at
any time during the performance period for that Incentive Compensation.

4. Recovery: Accounting Restatement.

In  the  event  the  Company  is  required  to  prepare  an  Accounting  Restatement,  the  Company  will  recover  reasonably  promptly  any  excess  Incentive
Compensation  received  by  any  Covered  Executive  during  the  three  completed  fiscal  years  immediately  preceding  the  date  on  which  the  Company  is
required to prepare an Accounting Restatement, including transition periods resulting from a change in the Company’s fiscal year as provided in Rule 10D-
1  of  the  Exchange  Act.  Incentive  Compensation  is  deemed  “received”  in  the  Company’s  fiscal  period  during  which  the  financial  reporting  measure
specified in the Incentive Compensation award is attained, even if the payment or grant of the Incentive Compensation occurs after the end of that period.
The determination of the time when the Company is “required” to prepare an Accounting Restatement shall be made in accordance with applicable SEC
and national securities exchange rules and regulations.

(a)

Definition of Accounting Restatement.

For the purposes of this Policy, an “Accounting Restatement” means the Company is required to prepare an accounting restatement of
its financial statements filed with the Securities and Exchange Commission (the “SEC”) due to the Company’s material noncompliance
with any financial reporting requirements under the federal securities laws (including any required accounting restatement to correct an
error in previously issued financial statements that is material to the previously issued financial statements, or that would result in a
material misstatement if the error were corrected in the current period or left uncorrected in the current period).

The determination of the time when the Company is “required” to prepare an Accounting Restatement shall be made in accordance with
applicable SEC and national securities exchange rules and regulations.

An Accounting Restatement does not include situations in which financial statement changes did not result from material non-compliance
with financial reporting requirements, such as, but not limited to retrospective: (i) application of a change in accounting principles; (ii)
revision to reportable segment information due to a change in the structure of the Company’s internal organization; (iii) reclassification
due to a discontinued operation; (iv) application of a change in reporting entity, such as from a reorganization of entities under common
control; (v) adjustment to provision amounts in connection with a prior business combination; and (vi) revision for stock splits, stock
dividends, reverse stock splits or other changes in capital structure.

(b)

Definition of Incentive Compensation.

For purposes of this Policy, “Incentive Compensation” means any compensation that is granted, earned, or vested based wholly or in
part  upon  the  attainment  of  a  “financial  reporting  measure”  (as  defined  in  paragraph  (b)  below),  including,  for  example,  bonuses  or
awards under the Company’s short and long-term incentive plans, grants and awards under the Company’s equity incentive plans, and
contributions  of  such  bonuses  or  awards  to  the  Company’s  deferred  compensation  plans  or  other  employee  benefit  plans.  Incentive
Compensation  does  not  include  awards  which  are  granted,  earned  and  vested  without  regard  to  attainment  of  financial  reporting
measures,  such  as  time-vesting  awards,  discretionary  awards  and  awards  based  wholly  on  subjective  standards,  strategic  measures  or
operational measures.

2

 
 
 
 
 
 
 
 
 
 
 
 
 
(c)

Financial Reporting Measures.

Financial reporting measures are those that are determined and presented in accordance with the accounting principles used in preparing
the  Company’s  financial  statements  (including  non-GAAP  financial  measures)  and  any  measures  derived  wholly  or  in  part  from  such
financial measures. For the avoidance of doubt, financial reporting measures include stock price and total shareholder return. A measure
need not be presented within the financial statements or included in a filing with the SEC to constitute a financial reporting measure for
purposes of this Policy.

(d)

Excess Incentive Compensation: Amount Subject to Recovery.

The  amount(s)  to  be  recovered  from  the  Covered  Executive  will  be  the  amount(s)  by  which  the  Covered  Executive’s  Incentive
Compensation  for  the  relevant  period(s)  exceeded  the  amount(s)  that  the  Covered  Executive  otherwise  would  have  received  had  such
Incentive Compensation been determined based on the restated amounts contained in the Accounting Restatement. All amounts shall be
computed without regard to taxes paid.

For Incentive Compensation based on financial reporting measures such as stock price or total shareholder return, where the amount of
excess compensation is not subject to mathematical recalculation directly from the information in an Accounting Restatement, the Board
will calculate the amount to be reimbursed based on a reasonable estimate of the effect of the Accounting Restatement on such financial
reporting measure upon which the Incentive Compensation was received. The Company will maintain documentation of that reasonable
estimate and will provide such documentation to the applicable national securities exchange.

(e)

Method of Recovery.

The  Board  will  determine,  in  its  sole  discretion,  the  method(s)  for  recovering  reasonably  promptly  excess  Incentive  Compensation
hereunder. Such methods may include, without limitation:

(i)

(ii)

(iii)

requiring reimbursement of compensation previously paid;

forfeiting  any  compensation  contribution  made  under  the  Company’s  deferred  compensation  plans,  as  well  as  any  matching
amounts and earnings thereon;

offsetting  the  recovered  amount  from  any  compensation  that  the  Covered  Executive  may  earn  or  be  awarded  in  the  future
(including,  for  the  avoidance  of  doubt,  recovering  amounts  earned  or  awarded  in  the  future  to  such  individual  equal  to
compensation  paid  or  deferred  into  tax–qualified  plans  or  plans  subject  to  the  Employee  Retirement  Income  Security  Act  of
1974 (collectively, “Exempt Plans”); provided that, no such recovery will be made from amounts held in any Exempt Plan of
the Company);

(iv)

taking any other remedial and recovery action permitted by law, as determined by the Board; or

(iv)

some combination of the foregoing.

3

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
5. No Indemnification or Advance.

Subject  to  applicable  law,  the  Company  shall  not  indemnify,  including  by  paying  or  reimbursing  for  premiums  for  any  insurance  policy  covering  any
potential losses, any Covered Executives against the loss of any erroneously awarded Incentive Compensation, nor shall the Company advance any costs or
expenses to any Covered Executives in connection with any action to recover excess Incentive Compensation.

6.

Interpretation.

The Board is authorized to interpret and construe this Policy and to make all determinations necessary, appropriate or advisable for the administration of
this Policy. It is intended that this Policy be interpreted in a manner that is consistent with the requirements of Section 10D of the Exchange Act and any
applicable rules or standards adopted by the SEC or any national securities exchange on which the Company's securities are listed.

7. Effective Date.

The effective date of this Policy is October 2, 2023 (the “Effective Date”). This Policy applies to Incentive Compensation received by Covered Executives
on or after the Effective Date that results from attainment of a financial reporting measure based on or derived from financial information for any fiscal
period ending on or after the Effective Date. In addition, this Policy is intended to be and will be incorporated as an essential term and condition of any
Incentive  Compensation  agreement,  change-in-control  plan,  or  any  other  plan  or  program  that  the  Company  establishes  or  maintains  on  or  after  the
Effective Date.

8. Amendment and Termination.

The Board may amend this Policy from time to time in its discretion and shall amend this Policy as it deems necessary to reflect changes in regulations
adopted by the SEC under Section 10D of the Exchange Act and to comply with any rules or standards adopted by the Nasdaq Stock Market or any other
securities exchange on which the Company’s shares are listed in the future.

9. Other Recovery Rights.

The  Board  intends  that  this  Policy  will  be  applied  to  the  fullest  extent  of  the  law.  Upon  receipt  of  this  Policy,  each  Covered  Executive  is  required  to
complete  the  Receipt  and  Acknowledgement  attached  as  Schedule  A  to  this  Policy.  The  Board  may  require  that  any  employment  agreement  or  similar
agreement relating to Incentive Compensation entered into on or after the Effective Date shall, as a condition to the grant of any benefit thereunder, require
a Covered Executive to agree to abide by the terms of this Policy. Any right of recovery under this Policy is in addition to, and not in lieu of, any (i) other
remedies  or  rights  of  compensation  recovery  that  may  be  available  to  the  Company  pursuant  to  the  terms  of  any  similar  policy  in  any  employment
agreement,  or  similar  agreement  relating  to  Incentive  Compensation,  unless  any  such  agreement  expressly  prohibits  such  right  of  recovery,  and  (ii)  any
other legal remedies available to the Company. The provisions of this Policy are in addition to (and not in lieu of) any rights to repayment the Company
may have under Section 304 of the Sarbanes-Oxley Act of 2002 and other applicable laws.

10. Impracticability.

The Company shall recover any excess Incentive Compensation in accordance with this Policy, except to the extent that certain conditions are met and the
Board has determined that such recovery would be impracticable, all in accordance with Rule 10D‑1 of the Exchange Act and the Nasdaq Stock Market or
any other securities exchange on which the Company’s shares are listed in the future.

11. Successors.

This  Policy  shall  be  binding  upon  and  enforceable  against  all  Covered  Executives  and  their  beneficiaries,  heirs,  executors,  administrators  or  other  legal
representatives.

INCENTIVE-BASED COMPENSATION CLAWBACK POLICY
RECEIPT AND ACKNOWLEDGEMENT

I, __________________________________________, hereby acknowledge that I have received and read a copy of the Incentive Compensation Recovery
Policy. As a condition of my receipt of any Incentive Compensation as defined in the Policy, I hereby agree to the terms of the Policy. I further agree that if
recovery of excess Incentive Compensation is required pursuant to the Policy, the Company shall, to the fullest extent permitted by governing laws, require
such  recovery  from  me  up  to  the  amount  by  which  the  Incentive  Compensation  received  by  me,  and  amounts  paid  or  payable  pursuant  or  with  respect
thereto, constituted excess Incentive Compensation. If any such reimbursement, reduction, cancelation, forfeiture, repurchase, recoupment, offset against
future grants or awards and/or other method of recovery does not fully satisfy the amount due, I agree to immediately pay the remaining unpaid balance to
the Company.
