Overview

PART I

We are a medical device company focused on the development of implantable devices used in the surgical treatment of the sacropelvic anatomy. We
have  pioneered  a  proprietary  minimally  invasive  surgical  implant  system,  which  we  call  iFuse,  to  fuse  the  sacroiliac  joint  to  treat  sacroiliac  joint
dysfunction that often causes severe lower back pain. Since we introduced iFuse in 2009, as of December 31, 2019, more than 44,000 procedures have been
performed by over 2,000 surgeons in the U.S. and 35 other countries.

The sacroiliac joint, which is the largest joint in the human body, can cause debilitating pain. Clinical studies have shown that 15% to 30% of all
chronic lower back pain is associated with the sacroiliac joint. Studies have also shown that the disability that results from disease of the sacroiliac joint is
comparable to the disability associated with a number of other serious orthopedic conditions, such as knee and hip arthritis and degenerative disc disease,
each of which has surgical solutions where an implant is used and a multi-billion dollar market exists. We believe iFuse is currently the market leading
implantable device used in minimally invasive surgical fusions of the sacroiliac joint in the U.S.

The iFuse system includes a series of patented triangular implants and the instruments we have developed to enable the procedure. The surgeon places
our implants across the sacroiliac joint, either from a lateral approach through the iliac, or hipbones into the sacrum, or from a posterior approach, through
the sacrum and into the iliac bone in the Bedrock technique. Surgeons typically use three iFuse implants to fuse a sacroiliac joint in the lateral procedure,
and the Bedrock technique involves placement of one iFuse implant in each sacroiliac joint, alongside another device crossing the joint and joining to the
spinal construct.

Our iFuse Implants have a triangular cross section which resists twisting of the implant within the bone in which it is implanted, regardless of the
surgical approach and technique used to place the implants. The triangular shape helps stabilize the joint, and the implants' porous surface enables biologic
fixation of the bone onto the implant, or bony ingrowth, which results in fusion. We hold issued patents on implants with cross-sections of many non-round
shapes, including the triangular shape we use for iFuse. We also hold issued patents for the method of placing those implants across the sacroiliac joint, as
well as other parts of the spine and pelvis. Each titanium iFuse implant is at least three times as strong as a typical eight-millimeter surgical screw and the
larger porous surface area of our implants allows for bony ingrowth.

We  introduced  our  second-generation  implant,  the  iFuse-3D,  in  2017.  This  patented  titanium  implant  combines  the  triangular  cross-section  of  the
iFuse implant with a proprietary 3D-printed porous surface and fenestrated design. These fenestrations allow the host bone to grow directly into the implant
structure,  or  bony  through-growth,  and  allow  the  surgeon  to  fill  the  implant  with  ground-up  bone  before  implanting  it,  which  some  surgeons  believe
accelerates bony through-growth. iFuse-3D implants have shown positive bony ingrowth and through-growth in cell culture and animal studies, whether or
not ground-up bone is used.

In April 2019, we received clearance from the U.S. Food and Drug Administration, or FDA, to promote the use of our iFuse system with the iFuse
Bedrock  technique  for  fusion  of  the  sacroiliac  joint  in  conjunction  with  multi-level  spinal  fusion  procedures,  to  provide  further  stabilization  and
immobilization  of  the  sacroiliac  joint.  We  received  CE  marking  and  began  marketing  our  iFuse  system  for  the  same  indication  in  Europe  in  December
2019.

We market our products primarily with a direct sales force as well as a number of distributors in the U.S., and with a combination of a direct sales

force and distributors in other countries.

In 2019 and 2018,  we  generated  revenue  of  $67.3 million and $55.4 million,  respectively,  a  growth  rate  of  22%,  and  incurred  net  losses  of  $38.4
million and $17.5 million, respectively. Our gross margins were 90% and 91% for 2019 and 2018, respectively. The number of iFuse procedures performed
globally in 2019 and 2018 was over 8,000 and 6,600, respectively. We generate our revenues from sales of the iFuse system.

Market Opportunity

Over  30  million  American  adults  are  estimated  to  have  chronic  lower  back  pain.  Our  experience  in  both  clinical  trials  and  commercial  settings
indicates that at least 30% of patients whose chronic lower back pain stems from the sacroiliac joint may be candidates for surgery with iFuse. Based on
our market experience and internal estimates, and the assumption that the average person suffering from sacroiliac joint dysfunction has been in pain for
five  years,  we  estimate  that  the  potential  market  for  iFuse  in  the  U.S.  could  be  279,000  patients  annually,  for  a  potential  annual  market  in  the  U.S.  of
approximately $2.7 billion. While we have made significant progress in penetrating this market, U.S. patients received only over 6,400 and 5,000 iFuse
procedures in 2019 and 2018, respectively.

Frequently, sacroiliac joint patients are aging and/or may have experienced one or more of the following events that have contributed to disruption or
degeneration  of  the  sacroiliac  joint:  falls,  previous  lumbar  surgery,  automobile  accidents,  and/or  pregnancies.  We  believe  that  Americans  spend
approximately $85.9 billion per year on spine problems and that approximately 65% of people who suffer from sacroiliac pain are women. In the U.S.,
iFuse  is  intended  for  sacroiliac  joint  fusion  for  conditions  including  sacroiliac  joint  dysfunction  that  is  a  direct  result  of  sacroiliac  joint  disruption  and
degenerative sacroiliitis. This includes conditions whose symptoms began during pregnancy or in the peripartum period and have persisted postpartum for
more than six months. The iFuse Implant System is also intended for sacroiliac fusion to augment immobilization and stabilization of the sacroiliac joint in
skeletally mature patients undergoing sacropelvic fixation as part of a lumbar or thoracolumbar fusion.

Diagnosis

It is often difficult to identify the source of lower back pain. As a result, some surgical procedures performed on the spine have a sub-optimal success
rate. For example, published studies of lumbar fusion have shown success rates of only approximately 60%. Unsuccessful spine surgery may result in failed
back surgery syndrome, which has been shown to result in high healthcare costs with poor overall relief of pain. Published studies have shown that the
sacroiliac joint is a cause of the pain in 32% to 43% of patients who have previously had lumbar fusion surgery and are experiencing recurrent low back
pain. We believe low success rates of lumbar fusion are likely related, in many cases, to failure to diagnose the sacroiliac joint as the correct cause of pain.

Since  we  launched  iFuse,  we  have  made  considerable  investments  in  teaching  healthcare  professionals  to  accurately  diagnose  sacroiliac  joint
disorders. We provide instruction and training on how to perform the provocative maneuvers in a physician’s office that can help establish the sacroiliac
joint as the source of pain. If provocative tests are positive, surgeons confirm the diagnosis by injecting a small amount of local anesthetic into the joint
under fluoroscopic guidance. The sacroiliac joint is confirmed as a pain source if the local anesthetic produces immediate and significant pain reduction. In
addition to the differentiated characteristics of our iFuse procedure and triangular iFuse implants, we believe that more accurate diagnosis is part of the
reason for the high success and patient satisfaction rates of the iFuse procedure.

Surgical Treatment of Sacroiliac Joint Disease

Patients with sacroiliac joint dysfunction frequently experience significant pain simply from sitting, standing, or rolling over in bed. These activities
result in small movements of the sacroiliac joints and pressure transferred across the joints. The pain can be exacerbated with activity - when a patient
walks or runs, for example, the shock from each step is transmitted up the leg, through the iliac bones of the pelvis to the sacroiliac joint. The initial goal in
fusion of the sacroiliac joint is to immediately stabilize the joint which rapidly reduces the pain. Following initial stabilization of the sacroiliac joint, the
goal is to permanently fuse the joint. We believe our proprietary triangular implants stabilize the joint better and more quickly than competing technologies
such as screws.

Surgical fusion of the sacroiliac joint with an open surgical technique was first reported in 1908, with further reports in the 1920s. The open procedure
uses plates and screws, requires a 6- to 12-inch incision and is extremely invasive. The iFuse procedure involves a 1- to 2-inch incision and is much less
invasive. For these reasons, we believe that open surgery for elective sacroiliac joint fusion has significant disadvantages compared to iFuse.

Due to its invasiveness, pain, long recovery time, and infrequent use, the open sacroiliac joint fusion procedure was rarely taught in medical school or
residency programs. Prior to our launch of iFuse, most spine surgeons were unfamiliar with the sacroiliac joint and had never performed a sacroiliac joint
fusion. As a result, when patients presented with lower back pain, spine surgeons often did not include evaluation of the sacroiliac joint in their diagnostic
work-up. Surgeons who did recognize the condition typically told their patients they had nothing to offer surgically.

5

Non-Surgical Treatment of Sacroiliac Joint Disease

Although a number of non-surgical treatments exist for sacroiliac joint pain, they did not provide the level of pain or disability relief seen with the

iFuse procedure for the patients participating in our randomized controlled clinical trials. Non-surgical treatments include:

• Medical therapy, including opiates and non-steroidal anti-inflammatory medications.

•

•

•

Physical therapy, which can involve exercises as well as massage.

Intra-articular injections of steroid medications, which are typically performed by physicians who specialize in pain treatment or anesthesia.

Radiofrequency ablation, or the cauterizing, of the lateral branches of the sacral nerve roots.

Our Solution - The iFuse Implant System

Our  iFuse  system,  which  includes  our  implants  and  instruments,  is  designed  to  address  the  shortcomings  of  alternative  treatments,  including  open
surgery, non-surgical management, and screw-based and other minimally invasive stabilization and fusion procedures. As shown in the graphic below, our
iFuse implants are triangular, and three implants are typically used in each procedure. Our implants are made of titanium and have a porous surface. Each
iFuse implant is at least three times the strength of a typical eight-millimeter surgical screw and the large porous surface area allows adherence of the bone
to the implants. We introduced the original iFuse implants in 2009, and our second-generation iFuse-3D implants in 2017.

The iFuse procedure is typically performed under general anesthesia. The surgeon uses a custom instrument set we provide to prepare a triangular
channel for each implant through the ilium, across the sacroiliac joint, and into the sacrum. An iFuse implant is then pressed into the triangular channel,
which is slightly smaller than the implant, creating what is known as an interference fit. The triangular cross section of our iFuse implants, as shown below,
prevents them from rotating. Our triangular iFuse implants cross the sacroiliac joint and provide immediate joint stability, which is why we believe pain
diminishes soon after the iFuse procedure. Over time, bone grows onto, and in the case of iFuse-3D into, the implants and across the joint, permanently
stabilizing or fusing the joint.

By  contrast,  open  fusion  of  the  sacroiliac  joint,  as  well  as  other  minimally  invasive  techniques,  typically  use  screws,  plates  and/or  bone  graft  for
fixation. When placed across the sacroiliac joint, standard orthopedic screws, which lack features to encourage biologic fixation, tend to rotate and loosen
over time. Because of the triangular shape, porous surface, strength, and other differentiating factors of our iFuse implants, we believe that our published
clinical data do not apply to other minimally invasive solutions. Little published evidence of safety, clinical effectiveness, durability, or economic utility
currently  exists  for  sacroiliac  fusion  devices  other  than  iFuse.  We  are  unaware  of  any  data  to  show  that  our  competitors’  sacroiliac  joint  screws,  with
features  allowing  biologic  fixation,  have  a  lower  rate  of  loosening  than  standard  orthopedic  screws.  In  addition,  placement  of  plates  for  open  fusion
procedures typically requires larger incisions and more invasive dissection, which results in longer recovery times and increased morbidity. We believe that
the differences between iFuse and other products, as well as the substantial published clinical evidence showing the safety and effectiveness of iFuse, are
the reason why a growing number of payors have recommended that iFuse be reimbursed for sacroiliac surgery to the exclusion of other technologies that
are designed for the procedure.

Our  implants  cross  the  sacroiliac  joint  and  provide  immediate  stability,  which  is  why  we  believe  pain  diminishes  soon  after  the  iFuse  procedure.
Typically, surgeons recommend protected weight-bearing for three weeks. However, post-operative instructions are patient-specific and some patients are
allowed to perform weight-bearing activities sooner. Follow-up studies have shown that bony bridging across the sacroiliac joint is present in the majority
of cases five years after the iFuse procedure.

6

Three  implants  are  used  in  most  lateral  iFuse  procedures.  Each  implant  bridges  across  the  joint  from  the  iliac  bone  to  the  sacrum.  Placing  each

implant requires four basic steps:

•

•

•

•

Pin. The surgeon inserts a guide pin through the iliac bone, across the sacroiliac joint and into the sacrum.

Drill. Surgeons drill over the guide pin, through the iliac bone, across the sacroiliac joint and just into the sacrum. This step is optional if using
the sharp-tip broach.

Broach. The surgeon impacts a triangular broach over the pin which prepares a triangular channel that is slightly smaller than the iFuse implant.

Implant.  The  surgeon  impacts  the  implant  into  the  triangular  channel  thereby  spanning  the  sacroiliac  joint  and  docking  the  implant  in  the
sacrum. The channel is slightly smaller than the implant, which produces an interference fit.

iFuse is a cannulated system, which means that the drill, broach and implants have hollow channels which fit over the pin for guidance purposes. As
is typical in many orthopedic procedures, a member of our team is normally present in the operating suite during surgery to provide technical assistance for
the use of iFuse.

We currently offer three custom instrument sets for surgical placement of iFuse implants in the body. The standard set comprises largely stainless steel
materials; the XL (Extra Long) set is the same as the standard set but most instruments are elongated by three inches for treatment of larger patients; and
the radiolucent set comprises instruments made with more radiolucent materials, such as PEEK and aluminum to improve visualization under fluoroscopy
during an iFuse procedure.

In addition to our iFuse and iFuse-3D platform technologies, we also provide enabling technologies for our surgeons. We introduced an instrument set
that  is  cleared  for  use  with  Medtronic’s  surgical  navigation  system,  allowing  the  surgeon  to  visualize  the  3D  positioning  of  certain  instruments  intra-
operatively. In March 2018, we introduced surgical pins cleared for use with the Mazor surgical robot, allowing the surgeon to robotically place the guide
pin according to a computer-generated surgical plan. In early 2019, we introduced our Decortication and Graft Delivery Systems that allow surgeons to
remove intra-articular cartilage and deliver flowable bone graft materials. In mid-2019, we introduced the iFuse Bedrock technique that supplements pelvic
fixation  in  deformity  and  degeneration  cases,  and  provides  enhanced  initial  stabilization  and  long-term  SI-joint  fusion.  In  late-2019,  we  introduced  the
iFuse Bone allograft for homologous use. 

Our Published Studies

iFuse is the only minimally invasive product for sacroiliac joint fusion commercially available in the U.S. that, to our knowledge, is supported by
substantial high-quality published evidence of safety, clinical effectiveness, durability, and economic utility. Our implants have a triangular cross section,
which resists twisting of the implant within the bone in which it is implanted, helping stabilize the joint even before fixation of the bone onto the implant,
or bony ingrowth, which results in fusion. Products from our competitors use screws to treat the sacroiliac joint, which do not resist twisting within the
bone as well as our patented triangular implants. A study we performed showed that our iFuse implants have more than six times the rotation resistance of a
screw designed for sacroiliac joint fusion. We hold issued patents on implants with cross-sections of many non-round shapes, including the triangular shape
we use for iFuse. We also hold issued patents for the method of placing those implants across the sacroiliac joint, as well as other parts of the spine and
pelvis. Each titanium iFuse implant is at least three times the strength of a typical eight-millimeter surgical screw and the larger porous surface area of our
implants allows for bony ingrowth. Three of our implants are typically used in each procedure.

The safety, durable effectiveness and cost effectiveness of iFuse are all supported by a large number of studies that have resulted in more than 80
published papers. Several of these papers publish results from three prospective multi-center studies (INSITE, SIFI, and iMIA) that we sponsored, two of
which were randomized controlled clinical trials. A prospective, follow-on study called “LOIS” that we also sponsored tracks certain study participants
from INSITE and SIFI for up to five years after their initial surgery. Additionally, there have been several studies showing longer-term follow-up of up to
six years.

7

INSITE Study Design

INSITE  is  a  randomized  controlled  study  conducted  in  the  U.S.  Positive  24-month  follow-up  results  were  published  in  August  2016  in  the
International Journal of Spine Surgery showing statistically significant and clinically important reduction in pain and disability after sacroiliac joint fusion
but very little response to maximal non-surgical treatment.

The INSITE clinical trial included 148 subjects treated at 19 centers in the U.S., with subjects randomized in a two-to-one ratio to either immediate
sacroiliac joint fusion with iFuse or non-surgical management. The study design allowed subjects in the non-surgical management group to cross over and
have surgery after six months. By 24 months after the start of the clinical trial, 89% of the non-surgical management group subjects still participating in the
trial had elected to cross over to have the iFuse procedure, primarily because they derived little clinical benefit from non-surgical treatments. The study’s
results can be summarized as follows:

•

•

Reduction in Pain. There was statistically significant and clinically important pain reduction in subjects treated with iFuse as compared to very
small responses in the same measures in those treated with non-surgical management. Subjects surgically treated with iFuse had mean 52- 54-
and  55-point  reductions  in  sacroiliac  joint  pain  at  6,  12  and  24  months,  respectively,  as  measured  by  the  Visual  Analog  Scale  ("VAS").  By
contrast, subjects in the non-surgical management group had only a mean 12-point reduction (p<0.0001) at six months. 12 points is below the
commonly  accepted  20-point  threshold  for  clinically  important  improvement.  In  addition,  the  non-surgical  management  group  subjects  who
elected  after  six  months  to  cross  over  to  have  the  iFuse  procedure  had  pain  reduction  similar  to  that  seen  in  subjects  originally  assigned  to
sacroiliac joint fusion with iFuse. At 24 months, the proportion of subjects with a reduction in VAS sacroiliac joint pain of 20 or more points due
to the assigned treatment only was 83% in the iFuse group and 10% in the non-surgical management group.

Reduction in Disability.  There  was  a  statistically  significant  and  clinically  important  reduction  in  disability  in  subjects  treated  with  iFuse  as
compared  to  very  little  response  in  those  treated  with  non-surgical  management.  Subjects  surgically  treated  with  iFuse  had  a  mean  27-point
reduction in disability at six months, on the 0–100 Oswestry Disability Index ("ODI"), while subjects in the non-surgical management group had
only a mean five-point reduction (p<0.0001). Five points is less than the commonly accepted 15-point threshold to denote a clinically important
response.  At  24  months,  the  iFuse  group  had  a  mean  28-point  reduction  in  ODI.  At  six  months,  the  proportion  of  subjects  with  ODI
improvements of at least 15 points was 72.5% with iFuse treatment and only 13.0% in those undergoing non-surgical management (p<0.0001 for
difference in response rate). In addition, the subjects who elected after six months to cross over to have the iFuse procedure had similar reduction
in  disability  as  the  subjects  originally  assigned  to  sacroiliac  joint  fusion  with  iFuse.  At  24  months,  the  proportion  of  subjects  with  an  ODI
improvement  of  at  least  15  points  with  the  assigned  treatment  only  was  68.2%  and  7.5%  in  the  iFuse  and  non-surgical  management  groups,
respectively (p<0.0001 for difference in response rate).

iMIA European Clinical Trial

iMIA is a second prospective, randomized clinical trial of sacroiliac joint fusion using iFuse compared to non-surgical management with a design
very similar to that of INSITE. iMIA is a randomized controlled study conducted in Europe. Positive 24-month results were published in March 2019 in
The  Journal  of  Bone  and  Joint  Surgery.  Like  INSITE,  results  from  iMIA  show  statistically  significant  and  clinically  profound  reduction  in  pain  and
disability after SI joint fusion but little improvement after non-surgical treatment.

SIFI Clinical Trial

Sacroiliac Joint Fusion with iFuse Implant System (“SIFI”), is a prospective, multicenter single-arm clinical trial. Eligibility criteria and endpoints
were identical to INSITE. SIFI is a single-arm study conducted in the U.S. Positive 24-month follow-up results were published in the International Journal
of Spine Surgery in April 2016, showing substantial and sustained reduction in pain and disability.

LOIS Clinical Trial

LOIS is a prospective follow-on study, enrolling subjects at a subset of INSITE and SIFI sites treated with iFuse. Study outcomes at four years were
published in July 2018 in Medical Devices: Evidence and Research. In September 2019, we announced the publication of the 5-year results, which showed
excellent durability of clinical responses and positive radiographic outcomes for SI-joint fusion using triangular titanium implants. Among 103 enrolled
subjects,  mean  sacroiliac  joint  pain  scores  decreased  54  points  from  baseline  prior  to  surgery.  Disability  scores  decreased  26  points  and  quality  of  life
improved 0.29 points, all of which are statistically significant, clinically meaningful and consistent with previously published LOIS 4-year results. The 5-
year results from LOIS demonstrated that improvements in pain, patient function and quality of life demonstrated at two years in INSITE and SIFI were
durable and sustained at five years. Independent radiographic analysis of CT scans at five years showed a high rate of bony apposition to implants on both
the sacral and iliac sides (98%) as well as a high rate of SI joint fusion (88% bridging bone). Patient satisfaction remained high for patients treated with the
iFuse Implant. There were no reported adverse events related to the study device or procedure at five years.

8

SALLY Clinical Trial

SALLY is a prospective single-arm multicenter trial of iFuse-3D for the treatment of sacroiliac joint dysfunction. The enrolled patient population was
very similar to that of INSITE, SIFI and iMIA. Early results from SALLY show preoperative and six-month pain scores that are nearly identical to those of
the three earlier prospective trials of iFuse. In addition, SALLY showed improvements in physical function tests and a larger reduction in opioid usage. A
manuscript describing early SALLY results was submitted for publication in a peer-reviewed journal in February 2019.

Other Published Clinical Studies

To date, several studies, some of which we did not sponsor, have been published on the safety and effectiveness of sacroiliac joint fusion using iFuse.
These are prospective or retrospective, single site or multi-site, and U.S. or Europe-based. These clinical studies demonstrate the iFuse procedure to be safe
and effective. These studies demonstrate pain reduction and/or ODI improvement that is statistically significant and clinically important. These additional
studies are consistent with the results of INSITE, iMIA, and SIFI, including the types and rates of adverse events observed.

A study in Neurosurgery published in April 2017 showed similar improvements in pain and disability in patients followed for up to six years. The
study  also  showed  a  substantial  reduction  in  the  number  of  subjects  using  opioids  in  patients  treated  with  iFuse  at  their  last  follow-up  visit.  At  the  last
follow-up  visit,  84%  of  patients  who  received  non-surgical  management  were  using  opioids,  while  only  7%  of  patients  treated  with  iFuse  were  using
opioids.

In addition to clinical evidence, a number of economic publications we financially supported, including those in ClinicoEconomics  and  Outcomes

Research, demonstrate that the iFuse procedure provides a cost savings to the healthcare system when compared to non-surgical management over time.

Coverage and Reimbursement

Coverage  and  reimbursement  for  iFuse  products  and  related  procedures  vary  by  setting  of  care,  payor  type,  and  region.  In  the  U.S.,  healthcare
providers that purchase iFuse products look to various third-party payors, such as Medicare, Medicaid, private commercial insurance companies, health
maintenance organizations, accountable care organizations, and other healthcare-related organizations, to cover and pay for all or part of the costs of these
procedures. These providers bill patients for any applicable deductibles or co-payments. Sales volumes and prices of company products will continue to
depend in large part on the availability of coverage and reimbursement from such third-party payors for both the surgeon's professional fee and the facility
fee which covers, among other things, the cost of implants used in iFuse procedures.

The  Medicare  program  is  commonly  used  as  a  model  for  how  private  payors  and  other  governmental  payors  develop  their  coverage  and
reimbursement policies for healthcare items and services, including iFuse procedures. Unless a national coverage policy exists for a particular technology,
each of the Medicare Administrative Contractors is permitted to make its own determination of whether that item or service is covered by Medicare.

Medicare’s reimbursement rates for the iFuse procedure vary due to geographic location, the nature of facility in which the procedure is performed
(i.e.,  hospital  inpatient  department,  hospital  outpatient  department,  or  ambulatory  surgical  center)  and  other  factors.  Medicare  reviews  and  updates  its
payment rates and methodologies for these settings of care annually, and rates can change from year to year. In addition, Congress can alter reimbursement
rates at any time by mandating changes to Medicare’s payment methodologies.

Similarly,  private  payor  coverage  policies  and  reimbursement  rates  tend  to  vary  across  payors  and  settings  of  care.  Payors  continually  review  the
clinical evidence for new technologies and can change their coverage policies without notice or deny payment if the product was not used in accordance
with the payor’s coverage policy. Payors also review and challenge the prices charged for products and procedures.

In  the  U.S.,  the  American  Medical  Association  ("AMA"),  generally  creates  specific  billing  codes  for  surgical  procedures  under  a  coding  system
known as Current Procedural Terminology ("CPT"), which surgeons must use to bill and receive reimbursement for our iFuse procedure. Once a CPT code
is established, the Centers for Medicare & Medicaid Services ("CMS"), typically establishes payment levels under Medicare while private payors establish
rates and coverage rules independently.

Prior  to  our  launch  of  iFuse,  Medicare  and  most  private  insurance  companies  reimbursed  surgeons  for  sacroiliac  joint  fusions  using  either  an
established Category I CPT code or an unlisted code. A Category I CPT code is typically assigned to procedures that are consistent with contemporary
medical practice and are widely performed. Procedures with a longstanding Category I CPT code are usually reimbursed.

9

However,  effective  July  1,  2013,  the  AMA’s  CPT  Editorial  Panel  created  a  new  Category  III  CPT  code  for  fusion  of  the  sacroiliac  joint  using  a
minimally invasive or percutaneous approach. Category III CPT codes are used for new and emerging technologies and are reimbursed sporadically. This
new code functionally redefined coding for sacroiliac joint fusions because it meant that minimally invasive or percutaneous fusion procedures should not
be billed by the surgeon using the general Category I CPT code for sacroiliac fusion surgery. This coding change was accompanied by the establishment of
a Medicare hospital outpatient prospective payment rate for facilities to bill for procedures with the new code.

Following  the  creation  of  the  new  Category  III  CPT  code,  a  number  of  papers  demonstrating  the  clinical  success  of  the  iFuse  procedure  were
published. As a result of these studies, along with the support of several professional medical specialty societies and leading academic surgeons, the AMA
CPT  Editorial  Panel  established  a  new  Category  I  CPT  code  specifically  for  sacroiliac  joint  fusion  surgery  using  a  minimally  invasive  or  percutaneous
approach.  This  new  Category  I  CPT  code  became  effective  on  January  1,  2015.  However,  the  new  code  did  not  immediately  lead  to  positive  coverage
decisions  by  payors.  In  many  cases,  the  payors  wanted  additional  published  evidence  before  deciding  to  cover  the  procedure.  As  a  result,  positive
reimbursement decisions covering the procedure have occurred over the last few years, and some payors are still in the process of making decisions based
on the most recent evidence.

In March 2015, our INSITE prospective, randomized controlled multi-center clinical trial was published. In June 2015, the largest spine society in the
world, the North American Spine Society ("NASS"), published a positive coverage recommendation, based on the clinical evidence, signaling to insurance
companies  and  Medicare  Administrative  Contractors  that  sacroiliac  joint  fusion  using  a  minimally  invasive  surgical  approach  should  be  routinely
reimbursed. In March 2015, the International Society for Advancement of Spine Surgery ("ISASS"), also published a similar, updated positive coverage
document signaling to insurance companies in the U.S. that evidence supports reimbursement for the procedure.

Coverage decisions for this code are made independently by each private insurance company and each of the Medicare Administrative Contractors
that  help  manage  Medicare.  The  process  of  obtaining  coverage  is  laborious.  As  of  June  30,  2016,  because  of  the  iFuse  clinical  evidence,  all  Medicare
Administrative  Contractors  were  covering  the  procedure.  At  the  time,  very  few  private  payors  were  covering.  As  of  December  31,  2018,  U.S.  payors
covering  256.5  million  lives  regularly  reimbursed  for  the  iFuse  procedures,  a  58%  increase  over  December  31,  2017.  As  of  December  31,  2019,  U.S.
payors covering 282.7 million lives regularly reimbursed for the iFuse procedures, a 10% increase over December 31, 2018.

Third-party payors, whether governmental or commercial, are also developing increasingly sophisticated methods of controlling healthcare costs. No
uniform policy of coverage and reimbursement for medical device products and services exists among third-party payors in the U.S. Therefore, coverage
and  reimbursement  for  medical  device  products  and  services  can  differ  significantly  from  payor  to  payor.  In  addition,  payors  continually  review  new
technologies  for  possible  coverage  and  can,  without  notice,  deny  coverage  for  these  products  and  procedures.  As  a  result,  the  coverage  determination
process is often a time-consuming and costly process that requires us to provide scientific and clinical support for the use of our products to each payor
separately, with no assurance that coverage and adequate reimbursement will be obtained or maintained if obtained.

In  addition  to  uncertainties  surrounding  coverage  policies,  there  are  periodic  changes  to  reimbursement.  Third-party  payors  regularly  update
reimbursement amounts and sometimes revise the methodologies used to determine reimbursement amounts. This includes annual updates to payments to
physicians, hospitals, and ambulatory surgical centers for procedures during which our products are used. An example of payment updates is the Medicare
program’s updates to hospital and physician payments, which are done on an annual basis pursuant to the pertinent statute and regulations.

Specialty  benefit  managers  and  companies  which  perform  healthcare  technology  assessments  have  significant  influence  on  coverage  decisions.  In
May  2016,  the  ECRI  Institute  Health  Technology  Assessment  Information  Service  published  a  positive  review  of  the  iFuse  Implant  System,  citing  our
clinical evidence. In January 2018, the Blue Cross Blue Shield Association, the licensor to all 36 Blue Cross and Blue Shield insurers across the U.S., wrote
a  favorable  review  of  the  clinical  evidence  conferring  a  positive  coverage  recommendation  for  minimally  invasive  sacroiliac  fusion,  but  only  when
performed with iFuse. In February 2018, Milliman Care Guidelines, a Hearst Company publication, also recommended coverage and in May 2018, AIM
Specialty Health, owned by Anthem, established coverage for only iFuse and none of our competitors. In October 2018, eviCore recommended our iFuse
system exclusively for sacroiliac joint fusion or stabilization.

Private Payors. Private payors also decide whether to cover and how much to pay on an individual basis. We target and track 65 of the largest private
payors. Of the targeted and tracked payors, 52 were covering regularly, or had announced coverage for, the iFuse procedure, while the remaining private
payors were reevaluating their coverage policies. As of December 31, 2019, of the private payors, 32 have issued positive coverage policies exclusive to
iFuse for sacroiliac joint fusion because of the clinical evidence. Further, 20 private payors are covering iFuse and other sacroiliac joint fusion products.

10

As of December 31, 2019, of the U.S. payors covering 282.7 million lives that reimburse for iFuse, 147.9 million lives are covered by private payors.

The table below summarizes the overall covered lives by payor type as of December 31, 2019:

Commercial, exclusive

Commercial, non-exclusive

Medicaid

Medicare

Military/Federal

Covered Lives (in
millions)

57.6

90.3

55.5

64.5

14.8

282.7

Note that because many individuals are covered by more than one health insurance plan or may switch plans during the year, the total number of
covered lives reported by the payors represented above may be larger than the number of individuals who have access to the iFuse procedure through their
health insurance provider at any given time.

In December 2019, CIGNA established a positive coverage policy for minimally invasive SI joint fusion using the iFuse Implant System. CIGNA is
the fourth largest commercial health plan in the U.S. with approximately 14.6 million members. Also in December 2019, Anthem, which is the second
largest commercial health plan in the U.S. with approximately 34.9 million members, published a positive coverage policy for minimally invasive SI joint
fusion procedures using the iFuse Implant System for the treatment of chronic SI joint pain or functional impairment, but only subsequent to pelvic girdle
trauma. The Anthem policy does not generally cover SI joint dysfunction due to degenerative sacroiliitis. There are other large and small private payors,
including Aetna and Humana, that have not published positive coverage policies for the procedure. Some of these non-covering payors are reevaluating
coverage given the latest data, but there can be no assurance they will reach positive coverage decisions. In most cases, the payors who are not covering are
reevaluating coverage. Many payors will only review their coverage policies for a procedure on a scheduled basis, which can be every few months or as
infrequently as once per year.

Prior to payor coverage, surgeons have been reluctant to get trained on a procedure for which they could not reliably be reimbursed. While we believe
the increased coverage described above will have a positive effect on the number of iFuse procedures and our associated revenue in the future, the effect
likely will happen with a lag time: after a positive coverage decision is made, a number of months may pass before it impacts the number of procedures and
associated revenue, since the surgeons have to be made aware of the coverage decision, in some cases attend on of our training courses to learn the surgical
technique,  schedule  re-examinations  of  patients  who  were  candidates  for  surgery  and  subsequently  schedule  surgeries  for  the  patients  who  are  still
candidates.

We  believe  that  it  generally  takes  between  6  and  24  months  for  a  surgeon  to  fully  incorporate  iFuse  into  his  or  her  practice  after  payors  initiate
coverage and the surgeon is trained. Further, the administrative burden on surgical practices can be substantial for patients where reimbursement coverage
is new, and some surgeons do not believe that the current average surgeon reimbursement is yet adequate to compensate them. However, as reimbursement
coverage has improved, surgeon interest in learning to diagnose the sacroiliac joint and perform iFuse procedures has been increasing.

Coverage Outside the U.S.

Outside the U.S., reimbursement levels vary significantly by country, and by region within some countries. Reimbursement is obtained from a variety
of  sources,  including  government-sponsored  and  private  health  insurance  plans,  and  combinations  of  both.  Some  countries  will  require  us  to  gather
additional clinical data before recognizing and granting broader coverage and reimbursement for our products.

Health Technology Assessment ("HTA") of medical devices is, however, becoming an increasingly common part of the pricing and reimbursement
procedures  in  some  EU  Member  States,  including  the  United  Kingdom,  France,  Germany,  Ireland,  Italy,  Spain  and  Sweden.  HTA  is  the  procedure
according to which the assessment of the public health impact, therapeutic impact and the economic and societal impact of use of a given medical device in
the national healthcare systems of the individual country is conducted. HTA generally focuses on the clinical efficacy and effectiveness, safety, cost, and
cost‑effectiveness of individual products as well as their potential implications for the healthcare system. Those elements of medical devices are compared
with  other  treatment  options  available  on  the  market.  The  outcome  of  HTA  regarding  specific  medical  devices  will  often  influence  the  pricing  and
reimbursement  status  granted  to  these  products  by  the  competent  authorities  of  individual  EU  Member  States.  The  extent  to  which  pricing  and
reimbursement decisions are influenced by the HTA of the specific medical device varies between EU Member States. In addition, pursuant to Directive
2011/24/EU on the application of patients’ rights in cross‑border healthcare, a voluntary network of national authorities or bodies responsible for HTA in
the individual EU Member States was established. The purpose of the network is to facilitate and support the exchange of scientific information concerning
HTAs.  This  may  lead  to  harmonization  of  the  criteria  taken  into  account  in  the  conduct  of  HTAs  between  EU  Member  States  and  in  pricing  and
reimbursement decisions and may negatively affect price in at least some EU Member States.

11

 
 
 
 
 
 
 
 
 
As  a  further  step  in  this  direction,  on  January  31,  2018,  the  European  Commission  adopted  a  proposal  for  a  regulation  on  HTA.  This  legislative
proposal is intended to increase cooperation among EU Member States in assessing health technologies, including new medical devices, and providing the
basis for cooperation at the EU level for joint clinical assessments in these areas. The proposal would permit EU Member States to use common HTA tools,
methodologies, and procedures across the EU, working together in four main areas, including joint clinical assessment of the innovative health technologies
with  the  most  potential  impact  for  patients,  joint  scientific  consultations  whereby  developers  can  seek  advice  from  HTA  authorities,  identification  of
emerging health technologies to identify promising technologies early, and continuing voluntary cooperation in other areas. Individual EU Member States
will continue to be responsible for assessing non-clinical (e.g., economic, social, ethical) aspects of health technology, and making decisions on pricing and
reimbursement. The European Commission has stated that the role of the draft HTA regulation is not to influence pricing and reimbursement decisions in
the individual EU Member States. However, this consequence cannot be excluded.

In  April  2017,  the  UK’s  National  Institute  for  Health  and  Care  Excellence  ("NICE"),  published  guidance  on  minimally  invasive  sacroiliac  joint
fusion,  recommending  that  the  procedure  be  available  to  properly  diagnosed  patients  in  the  UK  National  Health  System.  NICE  develops  guidance  and
quality standards in health and social care and is a worldwide leader in technology evaluations. The recommendation states that the safety and efficacy of
minimally invasive sacroiliac joint fusion surgery is adequate provided that standard arrangements are in place. Use with standard arrangements is the most
positive recommendation that NICE can make for an interventional procedure such as minimally invasive SI joint fusion. In October 2018, NICE published
medical technology guidance specific to the iFuse Implant System, recommending that it be used in the National Health System because of the evidence
demonstrating that treatment with iFuse improves pain, quality of life, and disability in properly selected patients. The continued relevance of the NICE
guidance following the departure of the UK from the EU on 31 January 2020 is yet to be determined. Additionally, in August 2018, the public hospital
system  in  France  announced  it  would  initiate  coverage  for  iFuse  exclusively  beginning  September  6,  2018.  Some  countries  will  require  us  to  gather
additional  clinical  data  before  recognizing  and  granting  broader  coverage  and  reimbursement  for  our  products.  It  is  our  intent  to  complete  the  requisite
clinical studies and obtain coverage and reimbursement approval beyond what we have today in countries where it makes economic sense to do so.

Medical Affairs and Education

We  have  created  a  medical  affairs  team  that  focuses  both  internally  and  externally.  Internally,  specialized  medical  knowledge,  and  practical
experience with iFuse are used to help train our sales, marketing, quality, reimbursement, clinical, regulatory, engineering, and product development teams.
This same specialized medical knowledge and practical experience allow us to create and execute a wide variety of programs to train the relevant external
medical  community,  to  assist  them  in  identifying  and  diagnosing  patients  with  sacroiliac  joint  dysfunction  and  in  performing  the  iFuse  procedure.  The
medical affairs team is led by a fellowship trained orthopedic spine surgeon. As of December 31, 2019, our U.S. faculty consisted of 107 surgeons, 26 pain
management  physicians,  22  nurse  practitioners/physician’s  assistants,  and  103  physical  therapists.  These  third-party  consultants  educate  surgeons,
physician’s assistants, nurses, physical therapists, and other healthcare professionals regarding sacroiliac joint diagnosis and the iFuse procedure.

Our surgeon training programs are for orthopedic spine surgeons, neurosurgeons, general orthopedic surgeons, and orthopedic trauma surgeons. Since
its  introduction,  over  2,000  surgeons  have  treated  patients  with  iFuse.  We  grew  our  active  surgeon  base  to  539  surgeons  as  of  December  31,  2019,
compared to 450 active surgeons as of December 31, 2018. We define an active surgeon to be a surgeon who has performed at least one case in the last
three months. The increase in active surgeons is primarily due to training of additional surgeons throughout the year.

We  also  have  a  large  number  of  educational  programs  for  the  broader  medical  community  including  primary  care  physicians  and  other  healthcare
practitioners that may manage a sacroiliac joint patient non-surgically, such as physical therapists, pain management physicians, and chiropractors. As of
December  31,  2019,  our  medical  affairs  team  and  physical  therapist  consultants  have  educated  over  7,700  physical  therapists  on  sacroiliac  joint
dysfunction, its diagnosis and iFuse as a potential treatment. We also work to educate case managers, facilities where the iFuse procedure is performed such
as hospitals, as well as payors and health plans. For example, as of December 31, 2019, we have trained over 1,300 case managers across the U.S. Case
managers help patients navigate the healthcare system so that they receive the appropriate treatment. In addition to the continuing education program for
case managers, we have created continuing education programs for physical therapists and chiropractors. As of December 31, 2019, our physical therapy
continuing education programs were approved in 47 states. These programs include instruction on the diagnosis and non-surgical treatment of sacroiliac
joint  dysfunction  due  to  degenerative  sacroiliitis  and  sacroiliac  joint  disruptions.  Our  medical  affairs  programs  focus  on  working  with  leading  spine
surgeons  to  educate  other  surgeons  on  the  differential  diagnosis  of  sacroiliac  joint  disorders  and  the  use  of  iFuse.  We  also  work  closely  with  medical
societies to raise the awareness of and teach the appropriate diagnosis of sacroiliac joint dysfunction and the associated treatment options.

12

Sales and Marketing

We  market  and  sell  iFuse  primarily  through  a  direct  sales  force  and  a  small  number  of  third-party  distributors.  Our  target  customer  base  includes
approximately 7,500 surgeons who perform spine and/or pelvic surgery, including orthopedic spine surgeons, neurosurgeons, general orthopedic surgeons,
and orthopedic trauma surgeons.

Our direct sales organization in the U.S. covered ten sales regions as of December 31, 2019. In each region, a number of territory sales managers act
as the primary customer contact. Our territory sales managers have extensive training and experience selling medical devices for spine problems and pain
management,  generally  focusing  on  emerging  technologies  and  markets.  For  large  and/or  high  volume  territories,  we  also  employ  territory  associate
representatives who cover cases. As of December 31, 2019, our U.S. sales force consisted of 56 territory sales managers directly employed by us, and 37
third-party distributors.

As  of  December  31,  2019,  we  had  39  employees  working  in  our  European  operations,  and  have  established  operations  in  Italy  (2010),  Germany
(2014), the United Kingdom (2015) and France (2019). As of December 31, 2019, our international sales force consisted of 19 sales representatives directly
employed by us and 27 exclusive third-party distributors, which together had sales in 35 countries through December 31, 2019. We anticipate continuing to
build our operations in the major European countries while establishing distributor arrangements in smaller ones. We intend to follow a similar model in
Europe  to  the  one  established  in  the  U.S.,  working  with  internationally  recognized  healthcare  professional  experts  as  we  expand  our  training  and
reimbursement activities. As of December 31, 2019, beyond Europe and the U.S., surgeons had performed the first iFuse procedures in Australia, Bahrain,
Canada, Cayman Islands, Hong Kong, Israel, Japan, Kuwait, New Zealand, Saudia Arabia, South Africa, and Turkey.

In addition to general sales and marketing training, we provide our sales organization with comprehensive, hands-on cadaveric and dry-lab training
sessions focusing on the clinical benefits of our products and how to use them. We believe our robust training and professional development programs have
been an important component of our success to date and will help support our anticipated future growth. We expect to continue to increase the size of our
sales organization in order to increase sales and market penetration and to provide the significant, ongoing level of customer support required by our sales
and marketing strategy.

Our business is affected by seasonal variations. For instance, we have historically experienced lower sales in the summer months and higher sales in

the last quarter of the fiscal year. However, taken as a whole, seasonality does not have a material impact on our financial results.

Research and Development

Since our initial launch of the iFuse Implant System, we have introduced a number of new product and procedure enhancements. An example is the
iFuse-3D  implant,  which  we  developed  over  several  years  and  launched  in  2017.  The  most  notable  instrument  enhancement  was  the  release  of  the
revamped instrument set that included a number of radiolucent instruments.

In 2017, we also introduced an instrument set that is cleared for use with Medtronic’s surgical navigation system, allowing the surgeon to visualize
the 3D positioning of certain instruments intra-operatively. In March 2018, we introduced surgical pins which may be used with the Mazor surgical robot,
allowing the surgeon to robotically place the guide pin according to a computer-generated surgical plan. In early 2019, we introduced our Decortication and
Graft Delivery Systems that allow surgeons to remove intra-articular cartilage and deliver flowable bone graft materials. In mid-2019, we introduced the
iFuse Bedrock technique that supplements pelvic fixation in deformity and degeneration cases and provides enhanced initial stabilization and long-term SI-
joint fusion. In late-2019, we introduced the iFuse Bone allograft for homologous use. 

We  expect  to  continue  developing  enhancements  to  iFuse  to  meet  our  customers’  changing  needs  and  improve  the  surgery’s  effectiveness.  For
example, we know that some surgeons use iFuse to treat trauma patients post-stabilization.  We are developing products and techniques to help surgeons
improve the treatment of these patients, and we will seek any additional regulatory clearances that may be required. We also design and manufacture Class
I instruments for our surgeon customers based on special requests under our “Non-Standard Product” program.

13

Competition

We  believe  that  we  were  the  first  company  to  develop,  manufacture,  and  market  a  minimally  invasive  implant  cleared  by  the  FDA  expressly  for
sacroiliac joint fusion other than a modified screw. Over the past several years, other companies have subsequently recognized the opportunity and have
entered the minimally invasive sacroiliac joint fusion market. However, all of these products are either screw-based or allograft products. We expect more
competitors to enter into the market and an increased number of new product introductions by existing competitors. Many of our competitors are large,
publicly traded companies that can dedicate far greater resources to the minimally invasive sacroiliac joint market than we can. These companies often
have wide product offerings for spine and orthopedic surgery, which allow them to bundle products in order to win large hospital group contracts and can
create a barrier to entry for us. For example, some of our competitors offer sacroiliac joint fusion products which integrate with their surgical navigation
and robotics platforms, enabling navigation of their procedures or performance of aspects of these procedures by surgical robots. Many of these companies
also  have  much  larger  sales  forces  than  ours,  which  allow  them  to  reach  more  surgeons.  We  also  expect  there  to  be  a  continued  push  for  non-surgical
alternatives.

In the U.S., we believe that our primary competitors currently are Globus Medical, Inc. and Medtronic plc. Our primary competitors in Europe are
Globus Medical and SIGNUS Medizintechnik GmbH. However, these customers sell screw-based products, which we believe to be weaker and less able to
resist rotation than our triangular iFuse implants. We also compete against non-hardware products, such as allograft bone implants. These allograft products
comprise human cells or tissues and are regulated by the FDA differently from implantable medical devices made of metallic or other non-tissue based
materials,  unless  these  customers  include  specific  claims  about  their  intended  use  which  exceed  a  homologous  use,  or  use  consistent  with  the  original
function of the donor tissue.

Based on our commercial experience and market research, we believe iFuse is currently used in the majority of minimally invasive surgical fusions of
the  sacroiliac  joint  in  the  U.S.  Our  triangular  titanium  implant  is  differentiated  from  other  screw-based  technologies  on  the  market.  iFuse  is  the  only
minimally  invasive  product  for  sacroiliac  joint  fusion  commercially  available  in  the  U.S.  that,  to  our  knowledge,  is  supported  by  published  clinical
evidence  including  randomized  controlled  studies  that  demonstrate  the  safety,  clinical  effectiveness,  durability,  and  economic  utility.  These  benefits  are
supported  by  more  than  80  published  papers.  We  have  received  exclusive  reimbursement  coverage  in  the  U.S.  by  certain  payors  based  upon  our
differentiated  product  and  quality  of  our  evidence.  We  believe  these  factors  provide  competitive  advantages  to  us  in  the  market.  The  following  are  the
primary competitive factors on which companies compete in our industry:

•

•

Intellectual Property

We protect our intellectual property through our pending patent applications and issued patents. As of December 31, 2019, we had been issued 40
patents in the U.S., and 10 patents outside of U.S. Also, as of December 31, 2019, we have 19 pending patent applications in the U.S. and 5 pending patent
applications outside of the U.S. We have focused the majority of our foreign patent efforts in China, Europe, and Japan. Our current U.S. patents on iFuse,
including the triangular shape, expire in August 2024. Our current U.S. patents on iFuse 3D, including the fenestrated design, expire in September 2035.
Our foreign patents will expire between August 2025 and October 2031.

We have 14 registered trademarks in the U.S. and have filed for 4 more. In other countries, we have focused on registering three primary trademarks:
“iFuse Implant System,” “SI-BONE,” and the SI-BONE logo. As of December 31, 2019, we have sought protection for at least 2 of these trademarks in 60
countries including the 28 European member countries of the Madrid Protocol.

We  also  rely  upon  trade  secrets,  know-how  and  continuing  technological  innovation,  and  may  rely  upon  licensing  opportunities  in  the  future,  to
develop  and  maintain  our  competitive  position.  We  may  seek  to  protect  our  proprietary  rights  through  a  variety  of  methods,  including  confidentiality
agreements  and  proprietary  information  agreements  with  suppliers,  employees,  consultants  and  others  who  may  have  access  to  proprietary  information,
under which they are bound to assign to us inventions made during the term of their employment.

The term of individual patents depends on the legal term for patents in the countries in which they are granted. In most countries, including the U.S.,
the patent term is generally 20 years from the earliest claimed filing date of a non-provisional patent application in the applicable country. There can be no
assurance  that  patents  will  be  issued  from  any  of  our  pending  applications  or  that,  if  patents  are  issued,  they  will  be  of  sufficient  scope  or  strength  to
provide meaningful protection for our technology. Notwithstanding the scope of the patent protection available to us, a competitor could develop treatment
methods or devices that are not covered by our patents but that compete with our proprietary technology and products. Furthermore, numerous U.S. and
foreign issued patents and patent applications owned by third parties exist in the fields in which we are developing products. Because patent applications
can  take  many  years  to  issue,  there  may  be  applications  currently  unknown  to  us,  which  may  later  result  in  issued  patents  that  our  existing  or  future
products or proprietary technologies may be alleged and/or found to infringe.

There has been substantial litigation regarding patent and other intellectual property rights in the medical device industry. In the future, we may need
to  engage  in  litigation  to  enforce  patents  issued  or  licensed  to  us,  to  protect  our  trade  secrets  or  know-how  and  brands,  to  defend  against  claims  of
infringement of the rights of others or to determine the scope and validity of the proprietary rights of others. Litigation could be costly and could divert our
attention  from  other  functions  and  responsibilities.  Adverse  determinations  in  litigation  could  reduce  the  barriers  to  entry  that  we  have  established  for
iFuse, or subject us to significant liabilities to third parties, require us to seek licenses from third parties or prevent us from manufacturing, selling or using
iFuse, any of which could severely harm our business.

Regulation

Domestic Regulation of Our Products and Business

Our research, development and clinical programs, as well as our manufacturing and marketing operations, are subject to extensive regulation in the
U.S.  and  other  countries.  Most  notably,  all  of  our  products  sold  in  the  U.S.  are  subject  to  the  Federal  Food,  Drug,  and  Cosmetic  Act  ("FDCA")  as
implemented  and  enforced  by  the  FDA.  The  FDA  governs  the  following  activities  that  we  perform  or  that  are  performed  on  our  behalf,  to  ensure  that
medical products distributed domestically or exported internationally are safe and effective for their intended uses:

•

•

•

•

•

product design, research, development, and manufacture;

product safety, testing, labeling, and storage;

record keeping procedures;

product marketing, promotion, advertising, sales, distribution, export, and import; and

post-marketing  surveillance,  complaint  handling,  medical  device  reporting,  reporting  of  deaths,  serious  injuries  or  device  malfunctions,  and
repair or recall of products.

There are numerous FDA regulatory requirements governing the clearance or approval and marketing of our products. These include:

•

•

product listing and establishment registration, which helps facilitate FDA inspections and other regulatory action;

investigational  device  exemptions  to  conduct  premarket  clinical  trials,  which  include  extensive  monitoring,  recordkeeping,  and  reporting
requirements;

15

•

•

•

•

Quality  System  Regulation  ("QSR"),  which  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 use or indication;

clearance of product modifications that could significantly affect safety or effectiveness or that would constitute a major change in intended use
of one of our cleared devices;

approval of product modifications that affect the safety or effectiveness of one of our approved devices;

• medical device reporting regulations, which require that manufacturers comply with FDA requirements to report if their device may have caused
or contributed to a death or serious injury, or has malfunctioned in a way that would likely cause or contribute to a death or serious injury if the
malfunction of the device or a similar device were to recur;

•

•

•

•

•

post-approval restrictions or conditions, including post-approval study commitments;

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

the FDA’s recall authority, whereby it can ask, or under certain conditions order, device manufacturers to recall from the market a product that is
in violation of governing laws and regulations;

regulations pertaining to voluntary recalls; and

notices of corrections or removals.

FDA Premarket Clearance and Approval Requirements

Unless an exemption applies, each medical device we wish to commercially distribute in the U.S. will require either premarket notification, or 510(k),
clearance or approval of a pre-market approval ("PMA") from the FDA. The FDA classifies medical devices into one of three classes. Devices deemed to
pose  lower  risks  are  placed  in  either  Class  I  or  II,  which  typically  requires  the  manufacturer  to  submit  to  the  FDA  a  premarket  notification  requesting
permission  to  commercially  distribute  the  device.  This  process  is  generally  known  as  510(k)  clearance.  Some  low  risk  devices  are  exempted  from  this
requirement. Devices deemed by the FDA to pose the greatest risks, such as life-sustaining, life-supporting or implantable devices, or devices deemed not
substantially equivalent to a previously cleared 510(k) device, are placed in Class III, requiring a PMA.

Class  I  devices  are  those  for  which  safety  and  effectiveness  can  be  assured  by  adherence  to  FDA’s  “general  controls”  for  medical  devices,  which
include  compliance  with  the  applicable  portions  of  the  FDA’s  Quality  System  Regulation,  or  QSR,  facility  registration  and  product  listing,  reporting  of
adverse medical events, and appropriate, truthful and non-misleading labeling, advertising, and promotional materials. Some Class I devices also require
premarket clearance by the FDA through the 510(k) premarket notification process described below.

Class  II  devices  are  subject  to  FDA’s  general  controls,  and  any  other  “special  controls”  deemed  necessary  by  FDA  to  ensure  the  safety  and
effectiveness of the device, such as performance standards, product-specific guidance documents, special labeling requirements, patient registries or post-
market surveillance. Premarket review and clearance by the FDA for Class II devices is accomplished through the 510(k) premarket notification procedure,
though certain Class II devices are exempt from this premarket review process. When a 510(k) is required, the manufacturer must submit to the FDA a
premarket  notification  submission  demonstrating  that  the  device  is  “substantially  equivalent”  to  a  legally  marketed  device,  which  in  some  cases  may
require submission of clinical data. Unless a specific exemption applies, 510(k) premarket notification submissions are subject to user fees. If the FDA
determines that the device, or its intended use, is not substantially equivalent to a legally marketed device, the FDA may place the device, or the particular
use of the device, into Class III, and the device sponsor must then fulfill much more rigorous premarketing requirements.

Class III devices, consisting of devices deemed by the FDA to pose the greatest risk, such as life-sustaining, life-supporting or implantable devices, or
devices deemed not substantially equivalent to a predicate device. The safety and effectiveness of Class III devices cannot be assured solely by general or
special  controls.  Submission  and  FDA  approval  of  a  premarket  approval,  or  PMA,  application  is  required  before  marketing  of  a  Class  III  device  can
proceed.  As  with  510(k)  submissions,  unless  subject  to  an  exemption,  PMA  submissions  are  subject  to  user  fees.  The  PMA  process  is  much  more
demanding than the 510(k) premarket notification process. A PMA application, which is intended to demonstrate that the device is safe and effective, must
be supported by extensive data, typically including data from preclinical studies and human clinical trials.

16

510(k) Clearance

To obtain 510(k) clearance for a medical device, an applicant must submit to the FDA a premarket notification submission demonstrating that the
proposed device is “substantially equivalent” to a legally marketed device, known as a “predicate device.” A legally marketed predicate device may include
a device that was legally marketed prior to May 28, 1976 for which a PMA is not required (known as a “pre-amendments device” based on the date of
enactment of the Medical Device Amendments of 1976), a device that has been reclassified from Class III to Class II or Class I, or a device that was found
substantially equivalent through the 510(k) process. A device is substantially equivalent if, with respect to the predicate device, it has the same intended use
and has either (i) the same technological characteristics, or (ii) different technological characteristics, but the information provided in the 510(k) submission
demonstrates that the device does not raise new questions of safety and effectiveness and is at least as safe and effective as the predicate device. A showing
of substantial equivalence sometimes, but not always, requires clinical data.

Before  the  FDA  will  accept  a  510(k)  submission  for  substantive  review,  the  FDA  will  first  assess  whether  the  submission  satisfies  a  minimum
threshold of acceptability. If the FDA determines that the 510(k) submission is incomplete, the FDA will issue a “Refuse to Accept” letter which generally
outlines the information the FDA believes is necessary to permit a substantive review and to reach a determination regarding substantial equivalence. An
applicant must submit the requested information before the FDA will proceed with additional review of the submission. By regulation, the FDA has 90
days from acceptance of the 510(k) submission for review to review and issue a determination. As a practical matter, clearance often takes longer. The FDA
may require additional information, including clinical data, to make a determination regarding substantial equivalence.

After a device receives 510(k) marketing clearance, any modification that could significantly affect its safety or effectiveness, or that would constitute
a major change or modification in its intended use, will require a new 510(k) marketing clearance or, if the modification changes the classification of the
product to Class III, PMA approval. The determination as to whether or not a modification could significantly affect the device’s safety or effectiveness is
initially  left  to  the  manufacturer  using  available  FDA  guidance.  Many  minor  modifications  today  are  accomplished  by  a  “letter  to  file”  in  which  the
manufacture documents the rationale for the change and why a new 510(k) is not required. However, the FDA may review such letters to file to evaluate
the regulatory status of the modified product at any time and may require the manufacturer to cease marketing and recall the modified device until 510(k)
clearance is obtained. The manufacturer may also be subject to significant regulatory fines or penalties.

PMA Approval

A  PMA  must  be  submitted  to  the  FDA  for  any  device  that  is  classified  in  Class  III  or  otherwise  cannot  be  cleared  through  the  510(k)  process
(although  the  FDA  has  discretion  to  continue  to  allow  certain  pre-amendment  Class  III  devices  to  use  the  510(k)  process).  PMA  applications  must  be
supported  by,  among  other  things,  valid  scientific  evidence  demonstrating  the  safety  and  effectiveness  of  the  device,  which  typically  requires  extensive
data, including technical, preclinical, clinical and manufacturing data. The PMA must also contain a full description of the device and its components, a full
description of the methods, facilities, and controls used for manufacturing, and proposed labeling. Following receipt of a PMA application, once the FDA
determines that the application is sufficiently complete to permit a substantive review, the FDA will formally accept the application for review. The FDA,
by  statute  and  by  regulation,  has  180  days  to  review  an  “accepted”  PMA  application,  although  the  review  of  an  application  more  often  occurs  over  a
significantly longer period of time, and can take up to several years. During the review period, the FDA will typically request additional information or
clarification of the information already provided. Also, an advisory panel of experts from outside the FDA may be convened to review and evaluate the
application and provide recommendations to the FDA as to the approvability of the device. The FDA may or may not accept the panel’s recommendation.

In addition, the FDA will generally conduct a pre-approval inspection of the manufacturing facility or facilities to ensure compliance with the QSR. If
the  FDA  evaluations  of  both  the  PMA  application  and  the  manufacturing  facilities  are  favorable,  the  FDA  will  either  issue  an  approval  letter  or  an
approvable letter, which usually contains a number of conditions that must be met in order to secure final approval of the PMA. If the FDA’s evaluation of
the PMA or manufacturing facilities is not favorable, the FDA will deny approval of the PMA or issue a not approvable letter. A not approvable letter will
outline the deficiencies in the application and, where practical, will identify what is necessary to make the PMA approvable. The FDA may also determine
that additional clinical trials are necessary, in which case the PMA approval may be delayed for several months or years while the trials are conducted.
Once granted, PMA approval may be withdrawn by the FDA if compliance with post-approval requirements, conditions of approval or other regulatory
standards  is  not  maintained  or  problems  are  identified  following  initial  marketing.  In  approving  a  PMA  the  FDA  may  also  require  some  form  of  post-
market  surveillance  when  necessary  to  protect  the  public  health  or  to  provide  additional  safety  and  effectiveness  data  for  the  device.  In  such  cases,  the
manufacturer might be required to follow certain patient groups for a number of years and makes periodic reports to the FDA on the clinical status of those
patients.

17

New  PMAs  or  PMA  supplements  are  required  for  modifications  that  affect  the  safety  or  effectiveness  of  a  PMA-approved  device,  including,  for
example,  certain  types  of  modifications  to  the  device’s  indication  for  use,  manufacturing  process,  labeling  and  design.  PMA  supplements  often  require
submission of the same type of information as a PMA, except that the supplement is limited to information needed to support any changes from the device
covered by the original PMA and may not require as extensive clinical data or the convening of an advisory panel.

De Novo Classification

Medical device types that the FDA has not previously classified as Class I, II or III are automatically classified into Class III regardless of the level of
risk they pose. The Food and Drug Administration Modernization Act of 1997 established a new route to market for low to moderate risk medical devices
that are automatically placed into Class III due to the absence of a predicate device, called the “Request for Evaluation of Automatic Class III Designation,”
or the de novo classification procedure. This procedure allows a manufacturer whose novel device is automatically classified into Class III to request down-
classification of its medical device into Class I or Class II on the basis that the device presents low or moderate risk, rather than requiring the submission
and approval of a PMA application. Prior to the enactment of the Food and Drug Administration Safety and Innovation Act of 2012, or the FDASIA, a
medical  device  could  only  be  eligible  for  de  novo  classification  if  the  manufacturer  first  submitted  a  510(k)  premarket  notification  and  received  a
determination  from  the  FDA  that  the  device  was  not  substantially  equivalent.  FDASIA  streamlined  the  de  novo  classification  pathway  by  permitting
manufacturers  to  request  de  novo  classification  directly  without  first  submitting  a  510(k)  premarket  notification  to  the  FDA  and  receiving  a  not
substantially  equivalent  determination.  Under  FDASIA,  the  FDA  is  required  to  classify  the  device  within  120  days  following  receipt  of  the  de  novo
application. If the manufacturer seeks reclassification into Class II, the manufacturer must include a draft proposal for special controls that are necessary to
provide  a  reasonable  assurance  of  the  safety  and  effectiveness  of  the  medical  device.  In  addition,  the  FDA  may  reject  the  reclassification  petition  if  it
identifies a legally marketed predicate device that would be appropriate for a 510(k) or determines that the device is not low to moderate risk or that general
controls would be inadequate to control the risks and special controls cannot be developed.

Clinical Trials

Clinical trials are generally required to support a PMA application and are sometimes required for 510(k) clearance. Such trials for implanted devices
such  as  iFuse  generally  require  an  investigational  device  exemption  application  ("IDE"),  approved  in  advance  by  the  FDA  for  a  specified  number  of
subjects and study sites, unless the product is deemed a nonsignificant risk device eligible for more abbreviated IDE requirements. Clinical trials are subject
to extensive monitoring, recordkeeping and reporting requirements. Clinical trials must be conducted under the oversight of an institutional review board
("IRB"), for the relevant clinical trial sites and must comply with FDA regulations, including but not limited to those relating to good clinical practices. To
conduct a clinical trial, we also are required to obtain the subjects’ informed consent in form and substance that complies with both FDA requirements and
state and federal privacy and human subject protection regulations. We, the FDA, or the IRB, could suspend a clinical trial at any time for various reasons,
including  a  belief  that  the  risks  to  study  subjects  outweigh  the  anticipated  benefits.  Even  if  a  trial  is  completed,  the  results  of  clinical  testing  may  not
adequately demonstrate the safety and effectiveness of the device or may otherwise not be sufficient to obtain FDA clearance or approval to market the
product in the U.S. Similarly, in Europe the clinical study must be approved by a local ethics committee and in some cases, including studies with high- risk
devices, by the ministry of health in the applicable country.

Pervasive and Continuing Regulation

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

•

•

•

•

•

Product listing and establishment registration, which helps facilitate FDA inspections and other regulatory action;

QSR, which 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 use or indications;

clearance of product modifications that could significantly affect safety or effectiveness or that would constitute a major change in intended use
of one of our cleared devices;

approval of product modifications that affect the safety or effectiveness of one of our approved devices;

• medical device reporting regulations, which require that manufacturers comply with FDA requirements to report if their device may have caused
or contributed to a death or serious injury, or has malfunctioned in a way that would likely cause or contribute to a death or serious injury if the
malfunction of the device or a similar device were to recur;

•

post-approval restrictions or conditions, including post-approval study commitments;

18

•

•

•

•

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

the FDA’s recall authority, whereby it can ask, or under certain conditions order, device manufacturers to recall from the market a product that is
in violation of governing laws and regulations;

regulations pertaining to voluntary recalls; and

notices of corrections or removals.

We  have  registered  our  facility  with  the  FDA  as  a  medical  device  manufacturer.  The  FDA  has  broad  post-market  and  regulatory  enforcement
powers. We are subject to announced and unannounced inspections by the FDA to determine our compliance with the QSR and other regulations, and these
inspections may include the manufacturing facilities of some of our subcontractors. Failure by us or by our suppliers to comply with applicable regulatory
requirements can result in enforcement action by the FDA or other regulatory authorities, which may result in sanctions including, but not limited to:

•

•

•

•

•

•

•

•

•

•

untitled letters, warning letters, fines, injunctions, consent decrees, and civil penalties;

unanticipated expenditures to address or defend such actions;

customer notifications for repair, replacement, refunds;

recall, detention or seizure of our products;

operating restrictions or partial suspension or total shutdown of production;

refusing or delaying our requests for 510(k) clearance or PMA approval of new products or modified products;

operating restrictions;

withdrawing 510(k) clearances or PMA approvals that have already been granted;

refusal to grant export approval for our products; or

criminal prosecution.

The  FDA  inspected  our  facilities  in  May  2014.  As  a  result,  we  received  a  Form  483  with  three  observations  that  have  been  since  been  corrected
following a corrective and preventative action plan. We responded to the Agency in writing and the matter was closed as of October 2014. To date, the
FDA has not taken any further actions with respect to the May 2014 inspection or its findings. The FDA inspected our facilities again in December 2016.
As a result, no findings were noted.

Promotional Materials - “Off-Label” Promotion

Advertising and promotion of medical devices, in addition to being regulated by the FDA, are also regulated by the Federal Trade Commission and by
state regulatory and enforcement authorities. If the FDA determines that our promotional materials or training constitutes promotion of an unapproved use,
it  could  request  that  we  modify  our  training  or  promotional  materials  or  subject  us  to  regulatory  or  enforcement  actions,  including  the  issuance  of  an
untitled  letter,  a  warning  letter,  injunction,  seizure,  civil  fine,  or  criminal  penalties.  It  is  also  possible  that  other  federal,  state,  or  foreign  enforcement
authorities might take action if they consider our promotional or training materials to constitute promotion of an unapproved use, which could result in
significant fines or penalties under other statutory authorities, such as laws prohibiting false claims for reimbursement. In that event, our reputation could
be damaged and adoption of the products would be impaired.

In addition, under the federal Lanham Act and similar state laws, competitors, and others can initiate litigation relating to advertising claims.

International Regulation of Our Products

Our research, development and clinical programs, as well as our manufacturing and marketing operations, are subject to extensive regulation in other
countries. For example, in the European Economic Area ("EEA") our devices are currently required to comply with the Essential Requirements concerning
medical  devices  that  are  imposed  by  the  Medical  Device  Directive  (Council  Directive  93/42/EEC)  and  the  related  national  implementing  legislation  of
individual EU member states as well as related guidance. Demonstration of compliance with these requirements entitles us to affix the CE mark to our
medical devices, without which they cannot be commercialized in the EEA.

19

To demonstrate compliance with the Essential Requirements, we must undergo a conformity assessment procedure, which varies according to the type
of  medical  device  and  its  classification.  Except  for  low  risk  medical  devices  (Class  I  with  no  measuring  function  and  which  are  not  sterile),  where  the
manufacturer can issue an EC Declaration of Conformity based on a self-assessment of the conformity of its products with the Essential Requirements, a
conformity assessment procedure requires the intervention of a Notified Body, which is an organization designated by the competent authorities of a EEA
country  to  conduct  conformity  assessments.  The  Notified  Body  typically  audits  and  examines  products’  Technical  File  and  the  quality  system  for  the
manufacture, clinical evaluation report, design and final inspection of our devices before issuing a CE Certificate of Conformity demonstrating compliance
with the relevant Essential Requirements. Following the issuance of this CE Certificate of Conformity, we can draw up an EC Declaration of Conformity
and  affix  the  CE  mark  to  the  products  covered  by  this  CE  Certificate  of  Conformity  and  the  EC  Declaration  of  Conformity.  We  have  successfully
completed several Notified Body audits since our original certification in November 2010. Following these audits, our Notified Body issued International
Standards Organization Certificates and CE Certificates of Conformity allowing us to draw up an EC Declaration of Conformity and affix the CE mark to
certain of our devices.

After the product has been CE marked and placed on the market in the EEA, we must comply with a number of regulatory requirements relating to:

•

•

•

•

•

registration of medical devices in individual EEA countries;

pricing and reimbursement of medical devices;

establishment of post-marketing surveillance and adverse event reporting procedures;

Field Safety Corrective Actions, including product recalls and withdrawals; and

interactions with physicians.

Failure  to  comply  with  these  requirements  may  result  in  enforcement  measures  being  taken  against  us  by  the  competent  authorities  of  the  EEA
countries.  These  can  include  fines,  administrative  penalties,  compulsory  product  withdraws,  injunctions,  and  criminal  prosecution.  Such  enforcement
measures would have an adverse effect on our capacity to market our products in the EEA and, consequently, on our business and financial position.

In May 2017, the Medical Device Regulation (Regulation 2017/745) was adopted. From May 26, 2020, the Medical Device Regulation will repeal
and replace the Medical Device Directive and the Active Implantable Medical Device Directive. Unlike directives, which must be implemented into the
national laws of the EU Member States, the Medical Device Regulation will be directly applicable in the EU Member States and, on the basis of the EEA
agreement,  in  Iceland,  Lichtenstein  and  Norway.  The  Medical  Device  Regulation  is,  among  other  things,  intended  to  establish  a  uniform,  transparent,
predictable  and  sustainable  regulatory  framework  across  the  EEA  for  medical  devices  and  ensure  a  high  level  of  safety  and  health  while  supporting
innovation. Once applicable, the Medical Device Regulation will, among other things:

•

•

•

•

•

strengthen the rules on placing medical devices on the market and reinforce surveillance once they are available;

establish explicit provisions on manufacturers’ responsibilities for the follow-up of the quality, performance and safety of devices placed on the
market;

improve the traceability of medical devices throughout the supply chain to the end-user or patient through a unique identification number;

set up a central database to provide patients, healthcare professionals and the public with comprehensive information on products available in the
European Union; and

strengthen the rules for the assessment of certain high-risk devices, such as implants, which may have to undergo an additional check by experts
before they are placed on the market.

The Medical Device Regulation substantially augments those aspects of the Medical Device Directive governing clinical investigations of medical
devices.  Among  others,  it  imposes  specific  obligations  concerning  incapacitated  subjects,  minors,  pregnant  or  breastfeeding  women  and  clinical
investigations in emergency situations. In addition to detailed provisions concerning the authorization and conduct of clinical investigations, the Regulation
imposes on non-EU sponsors a responsibility to appoint a legal representative established in the EU and an obligation on EU Member States to ensure that
systems for compensation for any damage suffered by a subject resulting from participation in a clinical investigation conducted in that jurisdiction are in
place and on sponsors and investigators the obligation to ensure they make use of these systems.

20

Once  applicable,  the  Medical  Device  Regulation  will  impose  increased  compliance  obligations  which  we  must  respect  if  we  wish  to  continue  to
access  the  EU  market.  This  includes  the  up-classification  of  some  of  our  devices.  Moreover,  the  scrutiny  imposed  by  Notified  Bodies  for  the  technical
documentation related these devices will increase considerably.

Further, the advertising and promotion of our products in the EEA is currently subject to the provisions of the Medical Devices Directive, Directive
2006/114/EC  concerning  misleading  and  comparative  advertising,  Directive  2005/29/EC  on  unfair  commercial  practices,  and  from  26  May  2020,  the
Medical Device Regulation, as well as other national legislation in the EEA countries governing the advertising and promotion of medical devices. These
laws may limit or restrict the advertising and promotion of our products to the general public and may impose limitations on our promotional activities with
healthcare professionals.

In November 2008, we received 510(k) clearance to market our first generation iFuse implant from the FDA. Since 2008, we have received additional
FDA 510(k) clearances for new instruments, additional implant sizes and labeling changes. In the U.S., the iFuse Implant System is intended for sacroiliac
fusion for conditions, including sacroiliac joint dysfunction that is a direct result of sacroiliac joint disruptions and degenerative sacroiliitis. This includes
conditions  where  symptoms  began  during  pregnancy  or  in  the  peripartum  period  and  have  persisted  postpartum  for  more  than  six  months.  The  iFuse
Implant  System  is  also  intended  for  sacroiliac  fusion  to  augment  immobilization  and  stabilization  of  the  sacroiliac  joint  in  skeletally  mature  patients
undergoing sacropelvic fixation as part of a lumbar or thoracolumbar fusion. In the future, we plan to pursue additional 510(k) clearances for new products
and changes to the current indication for iFuse.

In November 2010, we obtained a CE Certificate of Conformity and affixed a CE mark to our iFuse Implant System to allow commercialization of
iFuse in the EEA. In the EEA and Switzerland, iFuse is intended for sacroiliac joint fusion. Since 2010, we have added additional instruments, implant
sizes and labeling updates and iFuse-3D, our second generation iFuse implant, to our product offerings in Europe. We plan to continue to work with our
Notified Body to incorporate new products and labeling updates in our Technical Files for CE marking in Europe. Current delays in the revisions to the
current bilateral agreement between the EU and Switzerland necessary to ensure the on-going supply of our CE marked medical devices in Switzerland
following entry into application of the Medical Device Regulation may, however, affect this plan.

Since  July  2013,  we  have  obtained  approval  for  iFuse  in  regions  beyond  the  U.S.  and  the  EEA,  including  Australia,  Canada,  Hong  Kong,  Israel,

Malaysia, New Zealand, Saudi Arabia, Singapore and Taiwan. We are currently collecting information to determine our regulatory strategy in Japan.

Healthcare Fraud and Abuse

Federal and state governmental agencies and equivalent foreign authorities subject the healthcare industry to intense regulatory scrutiny, including
heightened  civil  and  criminal  enforcement  efforts.  These  laws  constrain  the  sales,  marketing  and  other  promotional  activities  of  medical  device
manufacturers by limiting the kinds of financial arrangements we may have with hospitals, physicians and other potential purchasers and prescribers of our
products. Federal healthcare fraud and abuse laws apply to our business when a customer submits a claim for an item or service that is reimbursable under
Medicare, Medicaid, or other federally funded healthcare programs. The laws that may affect our ability to operate include:

•

•

the  federal  Anti-Kickback  Statute,  which  prohibits,  among  other  things,  knowingly  and  willfully  soliciting,  receiving,  offering  or  paying
remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, lease, order,
arrangement for, or recommendation of, items or services for which payment may be made, in whole or in part, under federal healthcare programs,
such  as  the  Medicare  and  Medicaid  programs.  The  term  “remuneration”  has  been  broadly  interpreted  to  include  anything  of  value,  and  the
government can establish a violation of the Anti-Kickback Statute without proving that a person or entity had actual knowledge of, or a specific
intent to violate, the law;

the  federal  civil  False  Claims  Act,  which  prohibits,  among  other  things,  individuals  or  entities  from  knowingly  presenting,  or  causing  to  be
presented, false or fraudulent claims for payment of government funds; knowingly making, using, or causing to be made or used, a false record or
statement to get a false claim paid or to avoid, decrease, or conceal an obligation to pay money to the federal government. 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. Actions under the False Claims Act may be brought by the government or as a qui tam  action  by  a  private  individual  in  the  name  of  the
government and to share in any monetary recovery. There are also criminal penalties for making or presenting a false or fictitious or fraudulent
claim to the federal government;

21

•

•

•

the  federal  Health  Insurance  Portability  and  Accountability  Act  of  1996,  which  imposes  criminal  and  civil  liability  for,  among  other  actions,
knowingly  and  willfully  executing,  or  attempting  to  execute,  a  scheme  to  defraud  any  healthcare  benefit  program  including  private  third-party
payors,  or  knowingly  and  willfully  falsifying,  concealing,  or  covering  up  a  material  fact  or  making  a  materially  false,  fictitious,  or  fraudulent
statement  or  representation,  or  making  or  using  any  false  writing  or  document  knowing  the  same  to  contain  any  materially  false,  fictitious,  or
fraudulent statement or entry in connection with the delivery of or payment for healthcare benefits, items, or services;

the  federal  Physician  Payment  Sunshine  Act,  implemented  by  CMS  as  the  Open  Payments  program,  which  requires  manufacturers  of  drugs,
devices, biologics and medical supplies for which payment is available under Medicare, Medicaid, or the Children’s Health Insurance Program to
report  annually  to  the  CMS,  information  related  to  payments  and  other  “transfers  of  value”  made  to  physicians  (currently  defined  to  include
doctors, dentists, optometrists, podiatrists and chiropractors) and teaching hospitals, and requires applicable manufacturers to report annually to
CMS ownership and investment interests held by physicians and their immediate family members and payments or other “transfers of value” to
such physician owners. Beginning in 2022, applicable manufacturers also will be required to report information regarding payments and transfers
of  value  provided  (beginning  in  2021)  to  physician  assistants,  nurse  practitioners,  clinical  nurse  specialists,  certified  nurse  anesthetists,  and
certified nurse-midwives; and

analogous state and foreign 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  and  patients;  state  laws  that  require  device  companies  to
comply with the industry’s voluntary compliance guidelines and the applicable compliance guidance promulgated by the federal government or
otherwise restrict payments that may be made to healthcare providers and other potential referral sources; state beneficiary inducement laws, and
state  laws  that  require  device  manufacturers  to  report  information  related  to  payments  and  other  transfers  of  value  to  physicians  and  other
healthcare providers or marketing expenditures, many of which differ from each other in significant ways and may not have the same effect, thus
complicating compliance efforts.

If we or our employees are found to have violated any of the above laws we may be subject to administrative, civil and criminal penalties, including
imprisonment,  exclusion  from  participation  in  federal  health  care  programs,  such  as  Medicare  and  Medicaid,  significant  fines,  monetary  penalties  and
damages,  the  restructuring  or  curtailment  of  our  operations,  imposition  of  compliance  obligations  and  monitoring,  and  damage  to  our  reputation.  For  a
more detailed description of the federal and state health care fraud and abuse laws, see the risk factor “We and our sales representatives must comply with
U.S. federal and state fraud and abuse laws, including those relating to physician kickbacks and false claims for reimbursement, as well as equivalent
foreign laws” in the Risks Related to Our Legal and Regulatory Environment section of Item 1A of this Annual Report on Form 10-K.

The  U.S.  Foreign  Corrupt  Practices  Act  ("FCPA")  and  similar  anti-bribery  laws  in  other  countries,  such  as  the  United  Kingdom  Bribery  Act
("UKBA"),  generally  prohibit  companies  and  their  intermediaries  from  making  improper  payments  to  government  officials  and/or  other  persons  for  the
purpose of obtaining or retaining business. Our policies mandate compliance with these anti-bribery laws.

Violations  of  these  federal  and  state  fraud  and  abuse  laws  can  subject  us  to  administrative,  civil,  and  criminal  penalties,  including  imprisonment,

substantial fines, penalties, damages, and exclusion from participation in federal healthcare programs, including Medicare and Medicaid.

Data Privacy and Security Laws

We are also subject to various federal, state and foreign laws that protect the confidentiality of certain patient health information, including patient
medical  records,  and  restrict  the  use  and  disclosure  of  patient  health  information  by  healthcare  providers,  such  as  the  Health  Insurance  Portability  and
Accountability Act, and its implementing regulations, as amended by Health Information Technology for Economic and Clinical Health Act enacted under
the American Recovery and Reinvestment Act 2009 ("ARRA") (collectively, "HIPAA"), in the U.S.

HIPAA requires the notification of patients, reporting to the U.S. Department of Health and Human Services ("HHS"), and other compliance actions,
in the event of a breach of unsecured Protected Health Information ("PHI"). Required notification must be provided without unreasonable delay and in no
event later than 60 calendar days after discovery of the breach, under HIPAA. In addition, if the PHI of 500 or more individuals is improperly used or
disclosed, HHS would post the notification on its website, and we may be required to notify the media. Failure to comply with the HIPAA privacy and
security standards can result in civil monetary penalties up to $58,490 per violation, not to exceed $1.755 million per calendar year for non-compliance of
an identical provision, and, in certain circumstances, criminal penalties with fines up to $250,000 per violation and/or imprisonment.

22

In addition, even when HIPAA does not apply other federal and state laws impose security obligations. For example, according to the Federal Trade
Commission ("FTC"), failing to take appropriate steps to keep consumers’ personal information secure constitutes unfair acts or practices in or affecting
commerce  in  violation  of  Section  5(a)  of  the  FTCA,  15  U.S.C  §  45(a).  The  FTC  expects  a  company’s  data  security  measures  to  be  reasonable  and
appropriate in light of the sensitivity and volume of consumer information it holds, the size and complexity of its business, and the cost of available tools to
improve security and reduce vulnerabilities. Medical data is considered sensitive data that merits stronger safeguards.

In the European Union ("EU"), we are subject to laws relating to our collection, control, processing and other use of personal data (i.e. data relating to
an identifiable living individual). We process personal data in relation to our operations. We process data of our employees, consultants, certain individuals
who may be affiliated with our customers, including physician users of our products and, in the context of clinical investigations, patients. The personal
data  may  include  sensitive  personal  data  including  health  information.  The  data  privacy  regime  in  the  EU  includes  the  EU  General  Data  Protection
Regulation, or the GDPR, effective on May 25, 2018 and the E-Privacy Directive 2002/58/EC and the national laws implementing it. Each EU Member
State  may  adopt  additional  legislation  implementing  these  regulations  into  its  own  national  data  privacy  regime  and  therefore  the  laws  may  differ  by
jurisdiction, sometimes significantly. We need to ensure compliance with the rules in each jurisdiction where we are established or are otherwise subject to
local privacy laws.

The GDPR is directly applicable in each EU Member State. This should, in principle, result in a more uniform application of data privacy laws across
the EU. The GDPR imposes onerous accountability obligations requiring data controllers and processors to maintain a record of their data processing and
policies.  It  requires  data  controllers  to  be  transparent  and  to  disclose  to  data  subjects  (in  a  concise,  intelligible  and  easily  accessible  form)  how  their
personal information is to be used, imposes limitations on retention of information, increases requirements pertaining to pseudonymized (i.e., key-coded)
data, introduces mandatory data breach notification requirements and sets higher standards for data controllers to demonstrate that they have obtained valid
consent  for  certain  data  processing  activities.  Fines  for  non-compliance  with  the  GDPR  will  be  significant-the  greater  of  €  20  million  or  4%  of  global
turnover. The GDPR provides that EU Member States may introduce further conditions, including limitations, to the processing of genetic, biometric, or
health  data,  which  could  limit  our  ability  to  collect,  use  and  share  personal  data,  or  could  cause  our  compliance  costs  to  increase,  ultimately  having  an
adverse impact on our business. Each EU Member State may also adopt additional related legislation and guidance in its own national data privacy regime
and therefore the laws may differ by jurisdiction, sometimes significantly. We need to ensure compliance with the rules in each jurisdiction where we are
established or are otherwise subject to local privacy laws.

We are subject to the supervision of local data protection authorities in those jurisdictions where we are established or otherwise subject to applicable
law. We depend on a number of third parties in relation to our provision of our services, a number of which process personal data on our behalf. With each
such provider we enter into contractual arrangements to ensure that they only process personal data according to our instructions and applicable laws, and
that they have sufficient technical and organizational security measures in place to fulfil their related obligations. Where we transfer personal data outside
the EEA, we do so in compliance with the relevant data export requirements. We take our data protection obligations seriously, as any improper disclosure,
particularly with regard to our customers’ sensitive personal data, could negatively impact our business and/or our reputation.

Manufacturing and Supply

We use third-party manufacturers to produce our implants and instruments. Our primary suppliers for implants are rms Company ("RMS") for iFuse-
3D, which represents the majority of our implant sales, and Orchid MPS Holdings, LLC ("Orchid") for iFuse. To mitigate supply risk, we hold four to six
months  of  inventory  for  both  our  iFuse-3D  and  iFuse.  Most  of  our  instruments  have  secondary  manufacturing  suppliers  and  we  continually  work  with
additional manufacturers as our secondary suppliers. Substantially all of our products, including all of our implants, are manufactured in the U.S.

We  entered  into  a  non-exclusive  Manufacturing,  Quality  and  Supply  Agreement  with  RMS  in  February  2017,  which  was  amended  in  July  2017.
Pursuant  to  such  agreement,  RMS  manufactures  certain  of  our  implants  in  accordance  with  our  specifications,  including  both  purchased  and  sterilized
iFuse-3D implants, as well as uncoated machined implants which are subsequently coated to become our finished first generation iFuse implants. While the
agreement provides that we are required to purchase the amounts forecasted in a blanket purchase order, we are not required to purchase product in excess
of such forecasted amounts. In the initial three-year term of the agreement, the prices we pay for products are fixed under the agreement provided that if
order  volumes  deviate  from  forecasted  amounts  beyond  certain  thresholds,  we  or  RMS  may  request  to  negotiate  further  price  changes.  After  the  initial
term, the agreement automatically renews for successive one-year periods; provided, however, the agreement may be terminated early by either party, as
specified in the agreement. With respect to our first generation iFuse implant, the parts manufactured by RMS needs to be coated by Orchid to finish the
goods. RMS is currently our only supplier of iFuse-3D implants.

23

Our iFuse implants are provided by Orchid Bio-Coat, a division of Orchid Orthopedic Solutions LLC. In April 2016, we entered into a Quality and
Manufacturing Agreement with Orchid, which agreement was amended in March 2017, April 2019 and June 2019. Pursuant to such agreement, Orchid
manufactures certain of our implants in accordance with our specifications. While the agreement provides that we are required to purchase the amounts
forecasted in a blanket purchase order, we are not required to purchase product in excess of such forecasted amounts. In the first year of the agreement, the
prices we paid for products were fixed as specified in the agreement. On an annual basis thereafter, we meet with Orchid to review changes in direct costs
beyond certain thresholds and may negotiate changes to prices based on such changes in costs. In addition, the prices we pay for product may be increased
with our consent to the extent such products are ordered with delivery timeline shorter than agreed upon order timeline. The initial agreement had a term of
five years, and pursuant to subsequent amendments it is now automatically renewing for successive 30-day periods; provided, however, the agreement may
be terminated by either party with 30 days' notice, as specified in the agreement.

Aside  from  quality  agreements,  we  do  not  currently  have  any  significant  manufacturing  agreements  with  our  other  manufacturers  and  orders  are

primarily controlled through purchase orders.

We believe that our manufacturing operations, and those of our suppliers, comply with regulations mandated by the FDA, as well as Medical Devices
Directive  regulations  in  the  EEA.  Manufacturing  facilities  that  produce  medical  devices  or  component  parts  intended  for  distribution  world-wide  are
subject to regulation and periodic planned and unannounced inspection by the FDA and other domestic and international regulatory agencies.

In the U.S., products we sell are required to be manufactured in compliance with the FDA's Quality System Regulation, codified at 21 CFR Part 820,
which covers the methods used in, and the facilities used for, the design, testing, control, manufacturing, labeling, quality assurance, packaging, storage,
and shipping. In international markets, we are required to obtain and maintain various quality assurance and quality management certifications, including
those issued by DEKRA Certification, B.V., our notified body. DEKRA has issued the following international certifications: Quality Management System
ISO13485:2016 for our locations in Santa Clara, California, and Gallarate Italy, Full Quality Assurance Certification for the design and manufacture of
iFuse, and a Design Examination certificate for iFuse.

We are required to demonstrate continuing compliance with applicable regulatory requirements to maintain these certifications and will continue to be
periodically inspected by international regulatory authorities for certification purposes. Further, we and certain of our suppliers are required to comply with
all applicable regulations and current good manufacturing practices. As set forth above, these FDA and international regulations cover, among other things,
the methods and documentation of the design, testing, production, control, quality assurance, labeling, packaging, sterilization, storage, and shipping of our
products. Compliance with applicable regulatory requirements is subject to continual review and is monitored rigorously through periodic inspections. If
we or our manufacturers fail to adhere to current good manufacturing practice requirements, this could delay production of our products and lead to fines,
difficulties  in  obtaining  regulatory  approvals,  recalls,  enforcement  actions,  including  injunctive  relief  or  consent  decrees,  or  other  consequences,  which
could, in turn, have a material adverse effect on our financial condition or results of operations.

Product Liability and Insurance

The manufacture and sale of our products subjects us to the risk of financial exposure to product liability claims. Our products are used in situations
in which there is a risk of serious injury or death. We carry insurance policies which we believe to be customary for similar companies in our industry. We
cannot assure you that these policies will be sufficient to cover all or substantially all losses that we experience.

We endeavor to maintain executive and organization liability insurance in a form and with aggregate coverage limits that we believe are adequate for

our business purposes, but our coverage limits may prove not to be adequate in some circumstances.

Employees

As of December 31, 2019, we had 262 employees, including sales and marketing, product development, general administrative and accounting, both
domestically and internationally. As of December 31, 2019, we had a direct field sales organization of 107 in the U.S. and 19 in Europe. Our ability to
recruit, develop and retain highly skilled talent is a significant determinant of our success. We continue to emphasize employee development and training,
and  we  embrace  diversity  and  inclusion.  We  also  have  policies  setting  forth  our  expectations  for  nondiscrimination  and  a  harassment-free  work
environment. None of our employees is subject to a collective bargaining agreement, and we consider our relationship with our employees to be good.

24

Emerging Growth Company Status

We qualify as an “emerging growth company” as defined in Section 101 of the Jumpstart Our Business Startups Act of 2012 ("JOBS Act"). We will
continue to be an emerging growth company until December 31, 2023, unless one of the following occurs: (i) if our total annual gross revenues are $1.07
billion or more; or (ii) if we issued more than $1.0 billion in non-convertible debt in the past three years; or (iii) if we become a "large accelerated filer," as
defined in Rule 12b-2 of the Exchange Act.

 As an emerging growth company under the JOBS Act, we can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the
Securities Act for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of certain accounting
standards until those standards would otherwise apply to private companies. We have elected to avail ourselves of this exemption and, therefore, we will
not be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

As an emerging growth company, we are also exempt from Section 404(b) of the Sarbanes-Oxley Act of 2002 and Section 14A(a) and (b) of the
Exchange Act. Section 404(b) of the Sarbanes-Oxley Act of 2002 requires a public company’s auditor to attest to, and report on, management’s assessment
of  its  internal  controls.  Sections  14A(a)  and  (b)  of  the  Exchange  Act,  implemented  by  Section  951  of  the  Dodd-Frank  Act,  require  companies  to  hold
shareholder advisory votes on executive compensation and golden parachute compensation. As long as we qualify as an emerging growth company, we will
not be required to comply with the requirements of Section 404(b) of the Sarbanes-Oxley Act of 2002 and Section 14A(a) and (b) of the Exchange Act.

Smaller Reporting Company Status

We qualify as a “smaller reporting company” as defined under Rule 12b‑2 of the Exchange Act. We will continue to qualify as a smaller reporting
company if: (i) our public float is less than $250.0 million; or (ii) our annual revenues is less than $100.0 million and our public float is less than $700.0
million. As per guidance, we determine whether we qualify as a smaller reporting company annually as of the last business day of our second fiscal quarter.
As a smaller reporting company, we may use the smaller reporting company scaled disclosure accommodations of Regulation S-K and S-X in our filings,
including among others:

•

•

•

•

•

•

two years of income statements rather than three years as required by Rule 8-02 of Regulation S-X;

two-year management discussions and analysis comparison rather than three-year comparison as required by Item 303 of Regulation S-K;

no requirement to provide selected financial data table required by Item 301 of Regulation S-K;

no requirement to provide market risk disclosures required by Item 305 of Regulation S-K;

no requirement to provide supplemental financial information required by Item 302 of Regulation S-K; and

less  extensive  narrative  disclosure  than  required  of  other  reporting  companies,  particularly  in  the  description  of  executive  compensation  as
required by Item 402 of Regulation S-K.

Company History

SI-BONE  was  founded  in  2008  by  the  main  inventor  of  iFuse,  orthopedist  Mark  A.  Reiley,  M.D.,  our  President,  Chief  Executive  Officer,  and
Chairman, Jeffrey W. Dunn, and orthopedic surgeon Leonard Rudolf, M.D. Dr. Reiley previously invented balloon kyphoplasty and founded Kyphon Inc.,
which  was  sold  to  Medtronic  plc  in  2007.  Dr.  Reiley  also  invented  the  INBONE  total  ankle  replacement  system,  which  was  sold  to  Wright  Medical
Technology, Inc. in 2008.

Item 1A. Risk Factors

Investing  in  our  common  stock  involves  a  high  degree  of  risk.  Investors  should  carefully  consider  the  risks  described  below,  as  well  as  the  other
information in this Annual Report on Form 10-K, including our consolidated financial statements and the related notes and the section “Management’s
Discussion and Analysis of Financial Condition and Results of Operations,” before deciding whether to invest in our common stock. The occurrence of any
of the events or developments described below could materially and adversely affect our business, financial condition, results of operations, and growth
prospects. In such an event, the market price of our common stock could decline, and our stockholders may lose all or part of their investment. Additional
risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations.

Risks Related to Our Business and Our Industry

We have incurred significant operating losses since inception, we expect to continue to incur operating losses in the future, and we may not be able to
achieve or sustain future profitability.

We have incurred net losses since our inception in 2008. For the years ended December 31, 2019 and 2018, we had net losses of $38.4 million and
$17.5 million, respectively. As of December 31, 2019, we had an accumulated deficit of $195.6 million. We have financed our operations primarily through
the  net  proceeds  of  our  public  offerings  of  our  common  stock,  private  placements  of  equity  securities,  certain  debt-related  financing  arrangements,  and
from sales of our products. We have devoted substantially all of our resources to research and development of our products, sales and marketing activities,
investments  in  training  and  educating  surgeons  and  other  healthcare  providers,  and  clinical  and  regulatory  matters  for  our  products.  There  can  be  no
assurances that we will be able to generate sufficient revenue from our existing products or from any of our product candidates in development, and to
transition to profitability and generate consistent positive cash flows. We expect that our operating expenses will continue to increase as we continue to
build our commercial infrastructure, develop, enhance, and commercialize our existing and new products and incur additional operational and reporting
costs associated with being a public company. As a result, we expect to continue to incur operating losses for the foreseeable future and may never achieve
profitability. Furthermore, even if we do achieve profitability, we may not be able to sustain or increase profitability on an ongoing basis. If we do not
achieve profitability, it will be more difficult for us to finance our business and accomplish our strategic objectives.

Our expected future capital requirements may depend on many factors including expanding our surgeon base, the expansion of our sales force, and
the timing and extent of spending on the development of our technology to increase our product offerings. We may need additional funding to fund our
operations  but  additional  funds  may  not  be  available  to  us  on  acceptable  terms  on  a  timely  basis,  if  at  all.  We  may  seek  funds  through  borrowings  or
through additional rounds of financing, including private or public equity or debt offerings. If we raise additional funds by issuing equity securities, our
stockholders may experience dilution. Any future debt financing into which we enter may impose upon us additional covenants that restrict our operations,
including limitations on our ability to incur liens or additional debt, pay dividends, repurchase our common stock, make certain investments, and engage in
certain merger, consolidation or asset sale transactions. Any future debt financing or additional equity that we raise may contain terms that are not favorable
to us or our stockholders. Furthermore, we cannot be certain that additional funding will be available on acceptable terms, if at all. If we are unable to raise
additional capital or generate sufficient cash from operations to adequately fund our operations, we will need to curtail planned activities to reduce costs,
which will likely harm our ability to execute on our business plan and continue operations.

If  hospitals,  surgeons,  and  other  healthcare  providers  are  unable  to  obtain  coverage  and  reimbursement  from  third-party  payors  for  procedures
performed using our products, adoption of our products may be delayed, and it is unlikely that they will gain further acceptance.

Maintaining  and  growing  sales  of  our  products  depends  on  the  availability  of  adequate  coverage  and  reimbursement  from  third-party  payors,
including  government  programs  such  as  Medicare  and  Medicaid,  private  insurance  plans,  and  managed  care  programs.  Hospitals,  surgeons,  and  other
healthcare providers that purchase or use medical devices generally rely on third-party payors to pay for all or part of the costs and fees associated with the
procedures performed with these devices.

Adequate coverage and reimbursement for procedures performed with our products is central to the acceptance of our current and future products.
We may be unable to sell our products on a profitable basis if third-party payors deny coverage, continue to deny coverage or reduce their current levels of
payment, or if our costs of production increase faster than increases in reimbursement levels. For example, our sales decreased significantly after minimally
invasive sacroiliac joint fusion was assigned to a Category III Current Procedural Terminology ("CPT") code effective July 1, 2013. After implementation
of this Category III CPT Code, surgeons were no longer able to consistently obtain reimbursement for procedures performed using our products. However,
effective January 1, 2015, minimally invasive sacroiliac joint fusion was assigned to a Category I CPT Code.

26

Many  private  payors  refer  to  coverage  decisions  and  payment  amounts  determined  by  the  Centers  for  Medicare  and  Medicaid  Services  ("CMS"),
which  administers  the  Medicare  program,  as  guidelines  for  setting  their  coverage  and  reimbursement  policies.  By  December  31,  2016,  all  Medicare
Administrative  Contractors  were  regularly  reimbursing  for  minimally  invasive  sacroiliac  joint  fusion.  Private  payors  that  do  not  follow  the  Medicare
guidelines may adopt different coverage and reimbursement policies for procedures performed with our products. Private commercial payors have been
slower to adopt positive coverage policies for minimally invasive sacroiliac joint fusion, and many private payors still have policies that treat the procedure
as experimental or investigational and do not regularly reimburse for the procedure. Future action by CMS or third-party payors may further reduce the
availability of payments to physicians, outpatient surgery centers, and/or hospitals for procedures using our products.

The healthcare industry in the U.S. has experienced a trend toward cost containment as government and private insurers seek to control healthcare
costs. Payors are imposing lower payment rates and negotiating reduced contract rates with service providers and being increasingly selective about the
technologies  and  procedures  they  chose  to  cover.  For  example,  several  Blue  Cross  Blue  Shield  payors  have  adopted  policies  that  treat  3D-printed
orthopedic  implants  that  come  in  standard  sizes,  rather  than  customized  to  the  patient’s  anatomy,  such  as  our  iFuse-3D  implant,  as  experimental  and
investigational  and  therefore  not  eligible  for  reimbursement.  There  can  be  no  guarantee  that  we  will  be  able  to  provide  the  scientific  and  clinical  data
necessary to overcome these policies. Such policies may contribute to a decrease in sales of our iFuse-3D implants. Payors may adopt policies in the future
restricting  access  to  medical  technologies  like  ours  and/or  the  procedures  performed  using  such  technologies.  Therefore,  we  cannot  be  certain  that  the
procedures performed with each of our products will be reimbursed. There can be no guarantee that, should we introduce additional products in the future,
payors will cover those products or the procedures in which they are used.

Market acceptance of our products in foreign markets may depend, in part, upon the availability of coverage and reimbursement within prevailing
healthcare  payment  systems.  Reimbursement  and  healthcare  payment  systems  in  international  markets  vary  significantly  by  country  and  include  both
government-sponsored  healthcare  and  private  insurance.  We  may  not  obtain  additional  international  coverage  and  reimbursement  approvals  in  a  timely
manner, if at all. Our failure to receive such approvals would negatively impact market acceptance of our products in the international markets in which
those approvals are sought.

If  the  reimbursement  provided  by  third-party  payors  to  hospitals,  surgeons,  and  other  healthcare  providers  for  procedures  performed  using  our
products is insufficient, adoption and use of our products and the prices paid for our implants may decline.

When an iFuse procedure is performed, both the surgeon and the healthcare facility, either a hospital or ambulatory surgical center, submit claims for
reimbursement to the healthcare payor. Generally, the facility obtains a lump sum payment, or facility fee, for minimally invasive sacroiliac joint fusions.
Our products are purchased by the facility, along with other supplies used in the procedure. The facility must also pay for its own fixed costs of operation,
including  certain  operating  room  personnel  involved  in  the  procedure.  If  these  costs  exceed  the  facility  fee  reimbursement,  the  facility’s  managers  may
discourage  or  restrict  surgeons  from  performing  the  procedure  in  the  facility  or  using  certain  technologies,  such  as  our  iFuse  implants,  to  perform  the
procedure.

Effective  January  1,  2020,  the  national  average  Medicare  payment  to  hospital  outpatient  departments  is  $15,944  and  the  Medicare  payment  to  an
ambulatory surgical center for a sacroiliac joint fusion is $12,981. We believe that payments to facilities are generally adequate for these facilities to offer
the iFuse procedure. However, there can be no guarantee that these facility fee payments will not decline in the future. The number of iFuse procedures
performed and the prices paid for our implants may in the future decline if payments to facilities for minimally invasive sacroiliac joint fusions decline.

Surgeons  are  reimbursed  separately  for  their  professional  time  and  effort  to  perform  a  surgical  procedure.  Prior  to  reassignment  of  minimally
invasive  sacroiliac  joint  fusion  to  a  Category  III  CPT  Code,  the  national  average  Medicare  physician  fee  schedule  payment  to  surgeons  for  CPT  codes
commonly used to submit claims for reimbursement for the iFuse procedure was approximately $1,000 and the procedure was commonly covered by both
government and private commercial payors in the U.S. Effective January 1, 2020, the average Medicare payment for the Category I CPT code is $915.
Many  private  payors  set  their  payment  amounts  with  reference  to  the  Medicare  payment,  often  approximately  10%  to  33%  higher  than  the  Medicare
payment  for  a  procedure.  For  some  governmental  programs,  such  as  Medicaid,  coverage  and  reimbursement  differ  from  state  to  state,  and  some  state
Medicaid programs may not pay an adequate amount for the procedures performed with our products, if any payment is made at all.

We believe that some surgeons may continue to view the Medicare and commercial reimbursement amounts as insufficient for the procedure, given
the work effort involved with the procedure, including the time to diagnose the patient and obtain prior authorization from the patient’s health insurer if
necessary. Many private payors require extensive documentation of a multi-step diagnosis before authorizing minimally invasive sacroiliac joint fusion for
a patient. We believe that some private payors apply their own coverage policies and criteria inconsistently, and surgeons may not be able to consistently
have minimally invasive sacroiliac fusions approved and covered. The perception by physicians that the reimbursement for minimally invasive sacroiliac
joint fusion is insufficient to compensate them for the work required, including diagnosis, documentation, obtaining payor approval for the procedure, and
burden on their office staff, may negatively affect the number of procedures performed and may therefore impede the growth of our revenues or cause them
to decline.

27

If  healthcare  payors  reverse  decisions  to  cover  minimally  invasive  sacroiliac  joint  fusion  exclusively  when  performed  with  iFuse  and  choose  to
reimburse for procedures performed with competitive products, our market share could decline, adversely affecting our revenues.

As  of  December  31,  2019, 32  of  the  largest  65  U.S.  private  payors  that  we  track  and  target  have  issued  positive  coverage  policies  covering  the
patented  triangular  design  of  our  iFuse  implants  and  excluding  coverage  of  other  products  that  are  intended  to  fuse  the  sacroiliac  joint  because  of  the
clinical evidence supporting the use of iFuse and the lack of clinical evidence supporting the use of other products. Additionally, the public hospital system
in France initiated coverage for iFuse exclusively beginning September 6, 2018. We believe that payors have adopted these exclusive coverage decisions
due  to  the  strength  of  our  clinical  evidence  and  in  part  due  to  recommendations  of  specialty  benefit  managers  and  healthcare  technology  assessment
organizations. In 2018, AIM Specialty Health, Blue Cross Blue Shield Association Evidence Street, and eviCore Healthcare published positive coverage
recommendations to their constituents and payor customers, recommending that iFuse be covered exclusively. Clinical trials of the type and size necessary
to offer evidence of the safety and efficacy of competing products could be performed and could show that other products for sacroiliac joint fusion are as
effective  as,  or  more  effective  than,  iFuse.  Payors  could  also  abandon  their  decisions  to  cover  iFuse  exclusively  for  other  reasons.  If  healthcare  payors
covering a significant number of covered lives reverse their policies of covering minimally invasive sacroiliac joint fusion exclusively when performed
with  the  iFuse  system,  sales  of  our  iFuse  implants  could  decline  or  fail  to  grow,  which  could  adversely  affect  our  business,  results  of  operations  and
financial condition.

We may not be able to convince physicians that iFuse is an attractive alternative to our competitors’ products and that our procedure is an attractive
alternative to existing surgical and non-surgical treatments of the sacroiliac joint.

Surgeons play the primary role in determining the course of treatment in consultation with their patients and, ultimately, the product that will be used
to treat a patient. In order for us to sell our iFuse system successfully, we must convince surgeons through education and training that treatment with iFuse
is beneficial, safe, and cost-effective for patients as compared to our competitors’ products. If we are not successful in convincing surgeons of the merits of
iFuse, they may not use our product, and we will be unable to increase our sales and achieve or grow profitability.

Historically,  most  spine  surgeons  did  not  include  an  evaluation  of  the  sacroiliac  joint  in  their  diagnostic  work-up  because  they  did  not  have  an
adequate surgical procedure to perform for patients diagnosed with sacroiliac joint dysfunction. As a result, some patients with lower back pain resulting
from  sacroiliac  joint  dysfunction  are  misdiagnosed.  We  believe  that  educating  surgeons  and  other  healthcare  professionals  about  the  clinical  merits  and
patient benefits of iFuse is an important element of our growth. If we fail to effectively educate surgeons and other medical professionals, they may not
include a sacroiliac joint evaluation as part of their diagnosis and, as a result, those patients may continue to receive unnecessary surgical procedures or
only non-surgical treatment.

Surgeons may also hesitate to change their medical treatment practices for other reasons, including the following:

•

•

•

•

lack of experience with minimally invasive procedures;

perceived liability risks generally associated with the use of new products and procedures;

costs associated with the purchase of new products; and

time commitment that may be required for training.

Furthermore, we believe surgeons will not widely use iFuse unless they determine, based on experience, clinical data, and published peer-reviewed
publications, that surgical intervention provides benefits or is an attractive alternative to non-surgical treatments of sacroiliac joint dysfunction. In addition,
we  believe  support  of  our  products  relies  heavily  on  long-term  data  showing  the  benefits  of  using  our  products.  If  we  are  unable  to  provide  that  data,
surgeons may not use our products. In such circumstances, we may not achieve expected sales and may be unable to achieve profitability.

Many patients with sacroiliac joint dysfunction are cared for by pain physicians, who are generally trained as anesthesiologists or physical medicine
and rehabilitation specialists. These pain physicians often offer a variety of non-surgical and surgical interventions to sacroiliac joint dysfunction patients,
including,  but  not  limited  to,  steroid  injections,  radiofrequency  ablation  of  the  nerves  serving  the  sacroiliac  joint  and  implantation  of  neurostimulation
devices and other products intended to treat the sacroiliac joint. Our professional education program seeks to teach pain physicians, and other health care
providers, about the benefits of iFuse, in order to prompt these providers to refer their patients with sacroiliac joint dysfunction to surgeons who have been
trained to perform the iFuse procedure. These providers may, however, prefer to continue to treat these patients with the interventions they offer. If we are
unable to convince potential referring health care providers of the comparative benefits of iFuse, and we are therefore unable to prompt sufficient numbers
of these providers to refer their patients with sacroiliac joint dysfunction for treatment by surgeons trained to perform the iFuse procedure, sales of our
iFuse implants could decline or fail to grow, which could adversely affect our business, results of operations and financial condition.

28

 Surgeons and payors may not find our clinical evidence to be compelling, which could limit our sales and revenue, and on-going and future research

may prove our products to be less safe and effective than initially anticipated.

The products we currently market in the U.S. have either received premarket clearance under Section 510(k) of the U.S. Federal Food, Drug, and
Cosmetic Act ("FDCA"), or are exempt from premarket review. Those marketed in the European Union ("EU"), have been the subject of a CE Certificate
of Conformity. The 510(k) clearance process of the U.S. Food and Drug Administration ("FDA") requires us to document that our product is “substantially
equivalent” to another 510(k)-cleared products. The 510(k) process is shorter and typically requires the submission of less supporting documentation than
other FDA approval processes, such as a premarket approval, ("PMA"), and does not usually require pre-clinical or clinical studies. Additionally, to date,
we have not been required to complete clinical studies in connection with the sale of our products outside the U.S. As a result, while there are a number of
published studies relating to iFuse and minimally invasive sacroiliac joint surgery that support the safety and effectiveness of our products and the benefits
they  offer,  our  clinical  studies  may  lack  the  size  and  scope  of  randomized  controlled  clinical  trials  required  to  support  approval  of  a  PMA.  For  these
reasons, surgeons may be slow to adopt our products, third-party payors may be slow to provide coverage, and we may be subject to greater regulatory and
product  liability  risks.  Further,  future  patient  studies  or  clinical  experience  may  indicate  that  treatment  with  our  products  does  not  improve  patient
outcomes. Such results would slow the adoption of our products by surgeons, significantly reduce our ability to achieve expected sales, and could prevent
us from achieving profitability. Moreover, if future results and experience indicate that our products cause unexpected or serious complications or other
unforeseen negative effects, we could be subject to mandatory product recalls, suspension, or withdrawal of FDA clearance, and suspension, variation, or
withdrawal of our CE Certificates of Conformity, significant legal liability or harm to our business reputation, which could have a material adverse effect
on our results or operations and financial condition. Similar risks apply to product approvals and registrations in other countries outside the U.S. and the
EU as well.

Pricing  pressure  from  our  competitors,  changes  in  third-party  coverage  and  reimbursement,  healthcare  provider  consolidation,  payor  consolidation
and  the  proliferation  of  “physician-owned  distributorships”  may  impact  our  ability  to  sell  our  product  at  prices  necessary  to  support  our  current
business strategies.

If competitive forces drive down the prices we are able to charge for our product, our profit margins will shrink, which will adversely affect our
ability to invest in and grow our business. The sacroiliac joint fusion market has attracted numerous new companies and technologies. As a result of this
increased competition, we believe there will be continuing increased pricing pressure, resulting in lower gross margins, with respect to our products.

Even  to  the  extent  our  product  and  procedures  using  our  product  are  currently  covered  and  reimbursed  by  third-party  private  and  public  payors,
adverse changes in coverage and reimbursement policies that affect our products, discounts, and number of implants used may also drive our prices down
and harm our ability to market and sell our products.

We are unable to predict what changes will be made to the reimbursement methodologies used by third-party payors. We cannot be certain that under
current and future payment systems, in which healthcare providers may be reimbursed a set amount based on the type of procedure performed, such as
those utilized by Medicare and in many privately managed care systems, the cost of our products will be justified and incorporated into the overall cost of
the procedure. In addition, to the extent there is a shift from inpatient setting to outpatient settings, we may experience increased pricing pressure.

Consolidation in the healthcare industry, including both third-party payors and healthcare providers, could lead to demands for price concessions or
to  the  exclusion  of  some  suppliers  from  certain  of  our  markets,  which  could  have  an  adverse  effect  on  our  business,  results  of  operations,  or  financial
condition. Because healthcare costs have risen significantly over the past several years, numerous initiatives and reforms initiated by legislators, regulators,
and third-party payors to curb these costs have resulted in a consolidation trend in the healthcare industry to aggregate purchasing power. As the healthcare
industry consolidates, competition to provide products and services to industry participants has become and will continue to become more intense. This in
turn has resulted and will likely continue to result in greater pricing pressures and the exclusion of certain suppliers from important market segments as
group purchasing organizations, independent delivery networks, and large single accounts continue to use their market power to consolidate purchasing
decisions for hospitals. We expect that market demand, government regulation, third-party coverage, and reimbursement policies and societal pressures will
continue to change the worldwide healthcare industry, resulting in further business consolidations and alliances among our customers, which may reduce
competition, exert further downward pressure on the prices of our products, and adversely impact our business, results of operations, or financial condition.
As we continue to expand into international markets, we will face similar risks relating to adverse changes in coverage and reimbursement procedures and
policies in those markets.

Physician-owned  distributorships  ("POD"),  are  medical  device  distributors  that  are  owned,  directly  or  indirectly,  by  physicians.  These  physicians
profit from selling or arranging the sale of medical devices for use in procedures they perform on their own patients at hospitals that purchase the devices
from the POD. We currently do not engage with PODs. The proliferation of PODs could result in increased pricing pressure on our products or harm our
ability to sell our products to physicians who own or are affiliated with those distributorships.

29

We operate in a very competitive business environment and if we are unable to compete successfully against our existing or potential competitors, our
sales and operating results may be negatively affected and we may not grow.

Our currently marketed products are, and any future products we commercialize will likely be, subject to intense competition. Our field is subject to
rapid change and highly sensitive to the introduction of new products or other market activities of industry participants. Our ability to compete successfully
will depend on our ability to develop proprietary products that reach the market in a timely manner, receive adequate coverage and reimbursement from
third-party payors, and are safer, less invasive, and more effective than alternatives available for similar purposes as demonstrated in peer-reviewed clinical
publications. Because of the size of the potential market, we anticipate that other companies will dedicate significant resources to developing competing
products.

The number of competitors that we are aware of marketing sacroiliac joint fusion products in the U.S. has grown from zero to 23 since 2008. Some
of our current and potential competitors are major medical device companies that have substantially greater financial, technical, and marketing resources
than  we  do,  and  they  may  succeed  in  developing  products  that  would  render  our  products  obsolete  or  noncompetitive.  In  addition,  many  of  these
competitors  have  significantly  longer  operating  history  and  more  established  reputations  than  we  do.  Some  of  these  companies  sell  a  broad  suite  of
products that can be used together in the operating room in order to facilitate surgery, such as surgical imaging, navigation and robotic systems, or a large
number of implants intended to treat different conditions affecting the spine and pelvis. The ability of these competitors to sell these products together or as
part of larger purchasing arrangements may put as at a disadvantage.

In the U.S., we believe that our primary competitors currently are Medtronic plc and Globus Medical, Inc. Our primary competitors in Europe are
Globus Medical, Inc. and SIGNUS Medizintechnik GmbH. At any time, these or other industry participants may develop alternative treatments, products or
procedures for the treatment of the sacroiliac joint that compete directly or indirectly with our products. They may also develop and patent processes or
products  earlier  than  we  can  or  obtain  domestic  and  international  regulatory  clearances  or  approvals  and  CE  Certificates  of  Conformity  for  competing
products  in  the  European  Economic  Area  ("EEA"),  more  rapidly  than  we  can,  which  could  impair  our  ability  to  develop  and  commercialize  similar
processes or products. If alternative treatments are, or are perceived to be, superior to our products, sales of our products and our results of operations could
be negatively affected.

 Some  of  our  larger  competitors  are  either  publicly  traded  or  divisions  or  subsidiaries  of  publicly  traded  companies.  These  competitors  may  enjoy

several competitive advantages over us, including:

•

•

•

•

•

•

•

greater financial, human, and other resources for product research and development, sales and marketing, and legal matters;

significantly greater name recognition;

established relationships with surgeons, hospitals, and other healthcare providers;

large and established sales and marketing and distribution networks;

greater  experience  in  obtaining  and  maintaining  domestic  and  international  regulatory  clearances  or  approvals,  or  CE  Certificates  of
Conformity for products and product enhancements;

more expansive portfolios of intellectual property rights; and

greater ability to cross-sell their products or to incentivize hospitals or surgeons to use their products.

New participants have increasingly entered the medical device industry. Many of these new competitors specialize in a specific product or focus on a
particular market segment, making it more difficult for us to increase our overall market position. The frequent introduction by competitors of products that
are or claim to be superior to our products or that are alternatives to our existing or planned products may make it difficult to differentiate the benefits of
our products over competing products. In addition, the entry of multiple new products and competitors may lead some of our competitors to employ pricing
strategies that could adversely affect the pricing of our products and pricing in the market generally.

As a result, without the timely introduction of new products and enhancements, our products may become obsolete over time. If we are unable to
develop innovative new products, maintain competitive pricing, and offer products that surgeons and other physicians perceive to be as reliable as those of
our competitors, our sales or margins could decrease, thereby harming our business.

30

We currently manufacture and sell a single family of products focused on procedures, the goal of which is to stabilize and fuse the sacroiliac joint,
which could negatively affect our operations and financial condition.

We do not sell any product other than iFuse and related tools and instruments. Therefore, we are solely dependent on widespread market adoption of
iFuse and we will continue to be dependent on the success of this single product for the foreseeable future. There can be no assurance that iFuse will gain a
substantial degree of market acceptance among surgeons, patients or healthcare providers. Our failure to successfully increase sales of iFuse or any other
event impeding our ability to sell iFuse, would result in a material adverse effect on our results of operations, financial condition and continuing operations.

If clinical experience with our iFuse Bedrock technique does not result in positive outcomes for patients or if clinical trials involving the use of iFuse
Bedrock fail to show meaningful patient benefit, sales of our iFuse implants could be adversely impacted.

In  November  2018,  we  introduced  our  iFuse  Bedrock  technique,  in  which  spine  surgeons  place  iFuse  implants  across  the  sacroiliac  joint  using  a
different surgical approach to treat sacroiliac joint dysfunction at the same time they are fusing multiple levels of the spine above and affixing those spinal
fusion devices to the pelvis. In April 2019, the FDA cleared promotion of iFuse Bedrock for a broader and more general purpose, to provide additional
stability  and  immobilization  of  the  sacroiliac  joint  in  connection  with  a  thoracolumbar  fusion  procedure.  To  date,  clinical  experience  with  the  iFuse
Bedrock technique is limited and we have yet to complete a clinical trial to evaluate the iFuse Bedrock technique. Surgeons do not know if the addition of
iFuse  implants  to  the  implants  used  to  fuse  multiple  levels  of  the  lumbar  spine  will  result  in  patient  benefit.  If  surgeons'  clinical  experience  with  iFuse
Bedrock is not positive, or if our clinical trials do not show meaningful benefits to the patients undergoing this procedure, sale of our iFuse implants for this
indication could be adversely impacted, which could negatively affect our operations and financial condition.

If  we  are  unable  to  maintain  and  expand  our  network  of  direct  sales  representatives  and  third-party  distributors,  we  may  not  be  able  to  generate
anticipated sales.

As of December 31, 2019, our U.S. sales force consisted of 56 territory sales managers directly employed by us and 37 third-party distributors. As of
December 31, 2019, our international sales force consisted of 19 sales representatives directly employed by us and 27 exclusive third-party distributors,
which  together  have  had  sales  in  35  countries  through  December  31,  2019.  Our  operating  results  are  directly  dependent  upon  the  sales  and  marketing
efforts of both our direct sales force and of our third-party distributors.

As we launch new products and increase our marketing efforts with respect to existing products, we will need to expand the reach of our marketing
and sales networks. Our future success will depend largely on our ability to continue to hire, train, retain and motivate skilled direct sales representatives
and third-party distributors with significant technical knowledge in various areas, such as spine health and treatment. New hires require training and take
time to achieve full productivity. If we fail to train new hires adequately, or if we experience high turnover in our sales force in the future, we cannot be
certain that new hires will become as productive as may be necessary to maintain or increase our sales. Our intention is for our direct sales representatives
and third-party distributors to develop long-lasting relationships with the surgeons they serve. If our direct sales representatives or third-party distributors
fail to adequately promote, market and sell our products or decide to leave or cease to do business with us, our sales could significantly decrease.

We face significant challenges and risks in managing our geographically dispersed distribution network and retaining the individuals who make up
that network. Some of our international third-party distributors account for a significant portion of our international sales volume, and if any such third-
party distributor were to cease to distribute our products, our sales could be adversely affected. In such a situation, we may need to seek alternative third-
party distributors or increase our reliance on our direct sales representatives, which may not prevent our sales from being adversely affected. If a direct
sales representative or third-party distributor were to depart and be retained by one of our competitors, we may be unable to prevent them from helping
competitors  solicit  business  from  our  existing  customers,  which  could  further  adversely  affect  our  sales.  Because  of  the  intense  competition  for  their
services, we may be unable to recruit or retain additional qualified third-party distributors or to hire additional direct sales representatives to work with us.
Furthermore,  we  may  not  be  able  to  enter  into  agreements  with  them  on  favorable  or  commercially  reasonable  terms,  if  at  all.  Failure  to  hire  or  retain
qualified direct sales representatives or third-party distributors would prevent us from expanding our business and generating sales.

In addition, distribution arrangements are complex and time consuming to negotiate and document, especially outside the U.S. We may not be able to
negotiate distribution arrangements on a timely basis, on acceptable terms, or at all. If we are unable to do so, we may have to curtail the development of
our products, delay their potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures and undertake
development  or  commercialization  activities  at  our  own  expense.  If  we  elect  to  increase  our  expenditures  to  fund  development  or  commercialization
activities on our own, we may need to obtain additional capital, which may not be available to us on acceptable terms or at all. If we do not have sufficient
funds, we may not be able to further develop our products or bring them to market and generate revenue.

If we are unable to expand our sales and marketing capabilities domestically and internationally, we may not be able to effectively commercialize our

products, which would adversely affect our business, results of operations, and financial condition.

31

Our business could suffer if we lose the services of key members of our senior management, key advisors or personnel.

We are dependent upon the continued services of key members of our senior management and a limited number of key advisors and personnel. In
particular,  we  are  highly  dependent  on  the  skills  and  leadership  of  our  President,  Chief  Executive  Officer,  and  Chairman,  Jeffrey  W.  Dunn.  The  loss  of
members of our senior management team, key advisors or personnel, or our inability to attract or retain other qualified personnel or advisors, could have a
material adverse effect on our business, results of operations, and financial condition. We do not maintain “key person” insurance for any of our executives
or  employees.  In  addition,  several  of  the  members  of  our  executive  management  team  are  not  subject  to  non-competition  agreements  that  restrict  their
ability to compete with us. Accordingly, the adverse effect resulting from the loss of certain executives could be compounded by our inability to prevent
them from competing with us.

  Our  products  may  have  undesirable  side  effects  which  may  require  them  to  be  taken  off  the  market,  require  them  to  include  safety  warnings  or

otherwise limit their sales.

Unforeseen adverse events related to our products could arise either during clinical development or, if cleared, approved, or subject to CE Certificate
of Conformity, after the product has been marketed. In clinical research, the most common adverse event related to our implant was leg pain resulting from
misplacement. The most common adverse event for our implant procedure has been minor wound infections. Additional adverse effects from iFuse or any
of our other products could arise either during clinical development or, if approved, cleared, or subject to CE Certificate of Conformity, after the product
has been marketed.

If we or others later identify adverse events caused by our products:

•

•

•

•

•

•

•

•

sales of the product may decrease significantly, and we may not achieve the anticipated market share;

regulatory  authorities  or  our  Notified  Body  may  require  changes  to  the  labeling  of  our  product.  This  may  include  the  addition  of  labeling
statements, specific warnings, and contraindications and issuing field alerts to physicians and patients;

we may be required to change instructions regarding the way the product is implanted or conduct additional clinical trials;

we may be subject to limitations on how we may promote the product;

regulatory authorities may require us to take our approved product off the market (temporarily or permanently) or to conduct other field safety
corrective actions;

we may be required to modify our product;

we may be subject to litigation fines or product liability claims; and

our reputation may suffer.

Any  of  these  events  could  prevent  us  from  achieving  or  maintaining  market  acceptance  of  the  affected  product  or  could  substantially  increase

commercialization costs and expenses, which in turn could delay or prevent us from generating significant revenue from the sale of our products.

Various factors outside our direct control may adversely affect manufacturing, sterilization, and distribution of our products.

The manufacture, sterilization, and distribution of our products is challenging. Changes that our suppliers may make outside the purview of our direct
control can have an impact on our processes, quality of our products, and the successful delivery of products to our customers. Mistakes and mishandling
are not uncommon and can affect supply and delivery. Some of these risks include:

•

•

•

•

•

failure to complete sterilization on time or in compliance with the required regulatory standards;

transportation and import and export risk;

delays in analytical results or failure of analytical techniques that we will depend on for quality control and release of products;

natural disasters, labor disputes, financial distress, raw material availability, issues with facilities and equipment, or other forms of disruption to
business operations affecting our manufacturers or suppliers; and

latent defects that may become apparent after products have been released and that may result in a recall of such products.

If any of these risks were to materialize, our ability to provide our products to customers on a timely basis would be adversely impacted.

32

 We  are  dependent  on  a  limited  number  of  third-party  suppliers,  some  of  them  single-source  and  some  of  them  in  single  locations,  for  most  of  our

products and components, and the loss of any of these suppliers, or their inability to provide us with an adequate supply of materials in a timely and
cost-effective manner, could materially adversely affect our business.

We rely on third-party suppliers to supply substantially all of our products. For us to be successful, our suppliers must be able to provide us with
products  and  components  in  substantial  quantities,  in  compliance  with  regulatory  requirements,  in  accordance  with  agreed  upon  specifications,  at
acceptable prices, and on a timely basis. We do not have long-term supply contracts for some of our suppliers, and in some cases, even where we do have
agreements in place, we purchase important parts of the iFuse Implant System from a single supplier. Therefore, we cannot assure investors that we will be
able to obtain sufficient quantities of product in the future.

In  addition,  our  anticipated  growth  could  strain  the  ability  of  our  suppliers  to  deliver  an  increasingly  large  supply  of  products,  materials,  and
components.  Suppliers  often  experience  difficulties  in  scaling  up  production,  including  financial  issues,  or  problems  with  production  yields  and  quality
control and assurance. For example, from time to time, we have experienced certain delays and may experience delays from our suppliers in the future.

We  generally  use  a  small  number  of  suppliers  for  our  instruments  and  rely  on  RMS  for  iFuse-3D  implants  and  Orchid  for  iFuse  implants.  Our

dependence on such a limited number of suppliers exposes us to risks, including, among other things:

•

•

•

•

•

•

•

•

•

•

third-party contract manufacturers or suppliers may fail to comply with regulatory requirements or make errors in manufacturing that could
negatively affect the safety or effectiveness of our products or cause delays in shipments of our products;

third-party  contract  manufacturers  or  suppliers  may  fail  to  maintain  good  manufacturing  practices,  leading  to  quality  control  problems  or
regulatory findings that could cause disruptions in their manufacturing processes and lead to delays in shipments of our products;

we or our third-party manufacturers and suppliers may not be able to respond to unanticipated changes in customer orders, and if orders do not
match forecasts, we or our suppliers may have excess or inadequate inventory of materials and components;

we or our third-party manufacturers and suppliers may be subject to price fluctuations due to a lack of long-term supply arrangements for key
components;

we  or  our  third-party  manufacturers  and  suppliers  may  lose  access  to  critical  services  and  components,  resulting  in  an  interruption  in  the
manufacture, assembly and shipment of our systems;

we  may  experience  delays  in  delivery  by  our  third-party  manufacturers  and  suppliers  due  to  changes  in  demand  from  us  or  their  other
customers;

fluctuations  in  demand  for  products  that  our  third-party  manufacturers  and  suppliers  manufacture  for  others  may  affect  their  ability  or
willingness to deliver components to us in a timely manner;

our third-party manufacturers and suppliers may wish to discontinue supplying components or services to us for risk management reasons;

we may not be able to find new or alternative components or reconfigure our system and manufacturing processes in a timely manner if the
necessary components become unavailable; and

our  third-party  manufacturers  and  suppliers  may  encounter  financial  hardships  unrelated  to  our  demand,  which  could  inhibit  their  ability  to
fulfill our orders and meet our requirements.

If any one or more of these risks materialize, it could significantly increase our costs and impact our ability to meet demand for our products. If we
are unable to satisfy commercial demand for our system in a timely manner, our ability to generate revenue would be impaired, market acceptance of our
products  could  be  adversely  affected,  and  customers  may  instead  purchase  or  use  our  competitors’  products.  Additionally,  we  could  be  forced  to  seek
alternative sources of supply.

33

 In addition, most of our supply and manufacturing agreements do not have minimum manufacturing or purchase obligations. As such, with many of

our suppliers, we have no obligation to buy any given quantity of products, and the suppliers have no obligation to sell us or to manufacture for us any
given quantity of components or products. As a result, our ability to purchase adequate quantities of components or our products may be limited and we
may not be able to convince suppliers to make components and products available to us in some instances. Our suppliers may also encounter problems that
limit  their  ability  to  supply  components  or  manufacture  products  for  us,  including  financial  difficulties,  damage  to  their  manufacturing  equipment  or
facilities, product discontinuations or adverse findings in quality audits. As a result, there is a risk that certain components could be discontinued and no
longer available to us. We may be required to make significant “last time” purchases of component inventory that is being discontinued by the supplier to
ensure supply continuity. If we fail to obtain sufficient quantities of high quality components to meet demand for our products in a timely manner or on
terms acceptable to us, we would have to seek alternative sources of supply. Securing a replacement third-party manufacturer or supplier could be difficult.
The introduction of new or alternative manufacturers or suppliers also may require design changes to our iFuse system that are subject to domestic and
international regulatory clearances or approvals and the review of our Notified Body.

Because of the nature of our internal quality control requirements, regulatory requirements, and the custom and proprietary nature of the parts, we
may not be able to quickly engage additional or replacement suppliers for many of our critical components. We may also be required to assess any potential
new manufacturer’s compliance with all applicable regulations and guidelines, which could further impede our ability to manufacture our products in a
timely manner. As a result, we could incur increased production costs, experience delays in deliveries of our products, suffer damage to our reputation, and
experience an adverse effect on our business and financial results. Failure of any of our third-party suppliers to meet our product demand level would limit
our ability to meet our sales commitments to our customers and could have a material adverse effect on our business.

We  may  also  have  difficulty  obtaining  similar  components  from  other  suppliers  that  are  acceptable  to  the  FDA  our  Notified  Body  the  competent
authorities in the countries of the EEA, or other foreign regulatory authorities, and the failure of our suppliers to comply with strictly enforced regulatory
requirements could expose us to delays in obtaining clearances or approvals, regulatory action including warning letters, product recalls, termination of
distribution, product seizures, civil, administrative, or criminal penalties and the suspension, variation, or withdrawal of our CE Certificates of Conformity.
We could incur delays while we locate and engage qualified alternative suppliers, and we may be unable to engage alternative suppliers on favorable terms
or at all. Any such disruption or increased expenses could harm our commercialization efforts and adversely affect our ability to generate sales.

In addition, each of our third-party suppliers operates at a facility in a single location and substantially all of our inventory of component supplies and
finished goods is held at these locations. We, and our suppliers, take precautions to safeguard facilities, including acquiring insurance, employing back-up
generators,  adopting  health  and  safety  protocols,  and  utilizing  off-site  storage  of  computer  data.  However,  vandalism,  terrorism,  or  a  natural  or  other
disaster,  such  as  an  earthquake,  fire,  or  flood,  could  damage  or  destroy  equipment  or  our  inventory  of  component  supplies  or  finished  products,  cause
substantial delays in our operations, result in the loss of key information, and cause us to incur additional expenses. Our insurance may not cover our losses
in  any  particular  case.  In  addition,  regardless  of  the  level  of  insurance  coverage,  damage  to  our  or  our  suppliers’  facilities  could  harm  our  business,
financial condition, and operating results.

As our sales grow, we may encounter problems or delays in the assembly of our products or fail to meet certain regulatory requirements which could
result in an adverse effect on our business and financial results.

To become profitable, we must assemble our products in adequate quantities in compliance with regulatory requirements and at an acceptable cost.
Increasing our capacity to assemble and test our products will require us to improve internal efficiencies. We may encounter a number of difficulties in
increasing our assembly and testing capacity, including:

•

•

•

•

•

•

managing production yields;

maintaining quality control and assurance;

providing component and service availability;

maintaining adequate control policies and procedures;

hiring and retaining qualified personnel; and

complying with state, federal, and foreign regulations.

If we are unable to satisfy commercial demand for our iFuse system due to our inability to assemble and test, our ability to generate revenue would

be impaired, market acceptance of our products could be adversely affected and customers may instead purchase or use our competitors’ products.

34

 
If we do not enhance and broaden our product offerings through our research and development efforts, we may be unable to compete effectively.

In  order  to  increase  our  market  share  in  the  sacroiliac  joint  fusion  market,  we  must  enhance  and  broaden  our  product  offerings  in  response  to
changing customer demands and competitive pressures and technologies. We might not be able to successfully develop, obtain domestic and international
regulatory clearances or approvals, or CE Certificates of Conformity for, or market new products, and our future products might not be accepted by the
surgeons or the third-party payors who reimburse for many of the procedures performed with our products. The success of any new product offering or
enhancement to an existing product will depend on numerous factors, including our ability to:

•

•

•

•

•

properly identify and anticipate surgeon and patient needs;

develop and introduce new products or product enhancements in a timely manner;

adequately protect our intellectual property and avoid infringing upon the intellectual property rights of third parties;

demonstrate the safety and effectiveness of new products; and

obtain  the  necessary  domestic  and  international  regulatory  clearances  or  approvals  and  CE  Certificates  of  Conformity  for  new  products  or
product enhancements.

If we do not develop and obtain domestic and international regulatory clearances or approvals and CE Certificates of Conformity for new products or
product enhancements in time to meet market demand, or if there is insufficient demand for these products or enhancements, our results of operations will
suffer. Our research and development efforts may require a substantial investment of time and resources before we are adequately able to determine the
commercial viability of a new product, technology, material, or other innovation. In addition, even if we are able to successfully develop enhancements or
new generations of our products, these enhancements or new generations of products may not produce sales in excess of the costs of development and they
may be quickly rendered obsolete by changing customer preferences or the introduction by our competitors of products embodying new technologies or
features.

We are required to maintain adequate levels of inventory, the failure of which could consume our resources and reduce our cash flows.

As a result of the need to maintain adequate levels of inventory, we are subject to the risk of inventory obsolescence. Many of our products come in
sets, which feature components in a variety of sizes so that the implant or device may be customized to the patient’s needs. In order to market our products
effectively, we often maintain and provide surgeons and hospitals with back-up products and products of different sizes. For each surgery, fewer than all of
the components of the set are used, and therefore certain portions of the set may become obsolete before they can be used. In the event that a substantial
portion of our inventory becomes obsolete, it could have a material adverse effect on our earnings and cash flows due to the resulting costs associated with
the inventory impairment charges and costs required to replace such inventory.

The  size  and  future  growth  in  the  market  for  iFuse  has  not  been  established  with  precision  and  may  be  smaller  than  we  estimate,  possibly
materially. In addition, we estimate cost savings to the economy and healthcare system as a result of the iFuse procedure based on our market research.
If our estimates and projections overestimate the size of this market or these benefits and cost savings, our sales growth may be adversely affected.

We are not aware of an independent third-party study that reliably reports the potential market size for iFuse or cost savings as a result of the iFuse
procedure.  Therefore,  our  estimates  of  the  size  and  future  growth  in  the  market  for  our  iFuse  products,  including  cost  savings  to  the  economy  overall,
including patients and employers, and to the healthcare system and the number of people currently suffering from lower back pain who may benefit from
and be amenable to our iFuse procedure, is based on a number of internal and third-party studies, surveys, reports, and estimates. While we believe these
factors have historically provided and may continue to provide us with effective tools in estimating the total market for our iFuse products and procedures
and  health  cost  savings,  these  estimates  may  not  be  correct  and  the  conditions  supporting  our  estimates  may  change  at  any  time,  thereby  reducing  the
predictive  accuracy  of  these  underlying  factors.  For  example,  the  surveys  we  have  conducted  are  based  on  a  small  number  of  respondents  and  are  not
statistically significant and may have other limitations. The actual incidence of lower back pain, and the actual demand for our products or competitive
products, could differ materially from our projections if our assumptions and estimates are incorrect. As a result, our estimates of the size and future growth
in  the  market  for  our  iFuse  products  may  prove  to  be  incorrect.  In  addition,  actual  health  cost  savings  to  the  healthcare  system  as  a  result  of  the  iFuse
procedure may materially differ from those we expect. If the actual number of people with lower back pain who would benefit from our iFuse products and
the size and future growth in the market for iFuse products and related costs savings to the healthcare system is smaller than we have estimated, it may
impair our projected sales growth and have an adverse impact on our business.

35

Our results of operations could suffer if we are unable to manage our planned international expansion effectively.

Expansion  into  international  markets  is  an  element  of  our  business  strategy  and  involves  risk.  The  sale  and  shipment  of  our  products  across
international borders, as well as the purchase of components and products from international sources, subject us to extensive U.S. and foreign governmental
trade,  import,  and  export  and  customs  regulations  and  laws.  Compliance  with  these  regulations  and  laws  is  costly  and  exposes  us  to  penalties  for  non-
compliance. Other laws and regulations that can significantly affect us include various anti-bribery laws, including the U.S. Foreign Corrupt Practices Act
("FCPA"), and the United Kingdom Bribery Act ("UKBA"), anti-boycott laws, anti-money laundering laws, and regulations relating to economic sanctions
imposed  by  the  U.S.,  including  the  Office  of  Foreign  Asset  Control  of  the  U.S.  Treasury.  Any  failure  to  comply  with  applicable  legal  and  regulatory
obligations  in  the  U.S.  or  abroad  could  adversely  affect  us  in  a  variety  of  ways  that  include,  but  are  not  limited  to,  significant  criminal,  civil  and
administrative penalties, including imprisonment of individuals, fines and penalties, denial of export privileges, seizure of shipments and restrictions on
certain business activities. Also, the failure to comply with applicable legal and regulatory obligations could result in the disruption of our distribution and
sales activities.

In addition, some of the countries in which we sell or plan to sell our products are, to some degree, subject to various risks, including:

•

•

•

•

•

•

•

•

•

•

•

•

exposure to different legal and regulatory standards;

lack of stringent protection of intellectual property;

obstacles  to  obtaining  domestic  and  foreign  export,  import,  and  other  governmental  approvals,  permits,  and  licenses  and  compliance  with
foreign laws;

potentially adverse tax consequences and the complexities of foreign value-added tax systems;

adverse changes in tariffs and trade restrictions;

limitations on the repatriation of earnings;

difficulties in staffing and managing foreign operations;

transportation delays and difficulties of managing international distribution channels;

longer collection periods and difficulties in collecting receivables from foreign entities;

increased financing costs;

currency risks; and

political, social, and economic instability and increased security concerns.

These  risks  may  limit  or  disrupt  our  expansion,  restrict  the  movement  of  funds  or  result  in  the  deprivation  of  contractual  rights  or  the  taking  of

property by nationalization or expropriation without fair compensation.

Our goal of a successful international expansion depends, in part, on our ability to develop and implement policies and strategies that are effective in
anticipating  and  managing  these  and  other  risks  in  the  countries  in  which  we  plan  to  do  business.  Failure  to  manage  these  and  other  risks  may  have  a
material adverse effect on our operations in any particular country and on our business as a whole.

In the future our products may become obsolete, which would negatively affect operations and financial condition.

The medical device industry is characterized by rapid and significant change. There can be no assurance that other companies will not succeed in
developing  or  marketing  devices,  and  products  that  are  more  effective  than  our  iFuse  system  or  that  would  render  the  iFuse  system  obsolete  or
noncompetitive. Additionally, new surgical procedures, medications and other therapies could be developed that replace or reduce the importance of our
product. Accordingly, our success will depend in part on our ability to respond quickly to medical and changes through the development and introduction
of new products. Product development involves a high degree of risk and there can be no assurance that our new product development efforts will result in
any commercially successful products.

If we experience significant disruptions in our information technology systems, our business, results of operations, and financial condition could be
adversely affected.

The efficient operation of our business depends on our information technology systems. We rely on our information technology systems to effectively

manage:

•

•

sales and marketing, accounting, and financial functions;

inventory management;

36

 
•

•

engineering and product development tasks; and

our research and development data.

Our information technology systems are vulnerable to damage or interruption from:

•

•

•

•

earthquakes, fires, floods, and other natural disasters;

terrorist attacks and attacks by computer viruses or hackers or breach of our cybersecurity;

power losses; and

computer systems, or Internet, telecommunications, or data network failures.

 The failure of our information technology systems to perform as we anticipate or our failure to effectively implement new systems could disrupt our

entire operation and could result in decreased sales, increased overhead costs, excess inventory and product shortages, and legal liability issues, all of which
could have a material adverse effect on our reputation, business, results of operations, and financial condition.

In addition, we accept payments for many of our sales through credit card transactions, which are handled through a third-party payment processor.
As a result, we are subject to a number of risks related to credit card payments. As a result of these transactions, we pay interchange and other fees, which
may increase over time and could require us to either increase the prices we charge for our products or experience an increase in our costs and expenses. In
addition, as part of the payment processing process, we transmit our customers’ credit card information to our third-party payment processor. We may in
the future become subject to lawsuits or other proceedings for purportedly fraudulent transactions arising out of the actual or alleged theft of our customers’
credit card information if the security of our third-party credit card payment processor is breached. We and our third-party credit card payment processor
are also subject to payment card association operating rules, certification requirements and rules governing electronic funds transfers, which could change
or be reinterpreted to make it difficult or impossible for us to comply. If we or our third-party credit card payment processor fail to comply with these rules
or requirements, we may be subject to fines and higher transaction fees and lose our ability to accept credit card payments from our customers, and there
may be an adverse impact on our business.

We  may  seek  to  grow  our  business  through  acquisitions  of  or  investments  in  new  or  complementary  businesses,  products  or  technologies,  and  the
failure to manage acquisitions or investments, or the failure to integrate them with our existing business, could have a material adverse effect on us.

From  time  to  time,  we  expect  to  consider  opportunities  to  acquire  or  make  investments  in  other  technologies,  products,  and  businesses  that  may
enhance our capabilities, complement our current products, or expand the breadth of our markets or customer base. Potential and completed acquisitions
and strategic investments involve numerous risks, including:

•

•

•

•

•

•

•

•

problems assimilating the purchased technologies, products, or business operations;

issues maintaining uniform standards, procedures, controls, and policies;

unanticipated costs and liabilities associated with acquisitions;

diversion of management’s attention from our core business;

adverse effects on existing business relationships with suppliers and customers;

risks associated with entering new markets in which we have limited or no experience;

potential loss of key employees of acquired businesses; and

increased legal and accounting compliance costs.

We have no current commitments with respect to any acquisition or investment. We do not know if we will be able to identify acquisitions we deem
suitable, whether we will be able to successfully complete any such acquisitions on favorable terms or at all, or whether we will be able to successfully
integrate any acquired business, product, or technology into our business or retain any key personnel, suppliers, or distributors. Our ability to successfully
grow through acquisitions depends upon our ability to identify, negotiate, complete, and integrate suitable target businesses and to obtain any necessary
financing. These efforts could be expensive and time consuming, and may disrupt our ongoing business and prevent management from focusing on our
operations. If we are unable to successfully integrate any acquired businesses, products, or technologies effectively, our business, results of operations, and
financial condition will be materially adversely affected.

37

 We may enter into collaborations, in-licensing arrangements, joint ventures, strategic alliances, or partnerships with third-parties that may not result in

the development of commercially viable products or the generation of significant future revenue.

In the ordinary course of our business, we may enter into collaborations, in-licensing arrangements, joint ventures, strategic alliances, partnerships, or
other  arrangements  to  develop  products  and  to  pursue  new  markets.  We  have  not  entered  into  any  collaboration  arrangements  to  date.  Proposing,
negotiating, and implementing collaborations, in-licensing arrangements, joint ventures, strategic alliances, or partnerships may be a lengthy and complex
process. Other companies, including those with substantially greater financial, marketing, sales, technology, or other business resources, may compete with
us for these opportunities or arrangements. We may not identify, secure, or complete any such transactions or arrangements in a timely manner, on a cost-
effective basis, on acceptable terms or at all. We have limited institutional knowledge and experience with respect to these business development activities,
and  we  may  also  not  realize  the  anticipated  benefits  of  any  such  transaction  or  arrangement.  In  particular,  these  collaborations  may  not  result  in  the
development of products that achieve commercial success or result in significant revenue and could be terminated prior to developing any products.

Additionally, we may not be in a position to exercise sole decision-making authority regarding the transaction or arrangement, which could create the
potential risk of creating impasses on decisions, and our future collaborators may have economic or business interests or goals that are, or that may become,
inconsistent with our business interests or goals. It is possible that conflicts may arise with our collaborators, such as conflicts concerning the achievement
of performance milestones, or the interpretation of significant terms under any agreement, such as those related to financial obligations or the ownership or
control of intellectual property developed during the collaboration. If any conflicts arise with any future collaborators, they may act in their self- interest,
which  may  be  adverse  to  our  best  interest,  and  they  may  breach  their  obligations  to  us.  In  addition,  we  may  have  limited  control  over  the  amount  and
timing of resources that any future collaborators devote to our or their future products.

Disputes between us and our collaborators may result in litigation or arbitration which would increase our expenses and divert the attention of our
management. Further, these transactions and arrangements will be contractual in nature and will generally be terminable under the terms of the applicable
agreements and, in such event, we may not continue to have rights to the products relating to such transaction or arrangement or may need to purchase such
rights at a premium. If we enter into in-bound intellectual property license agreements, we may not be able to fully protect the licensed intellectual property
rights or maintain those licenses. Future licensors could retain the right to prosecute and defend the intellectual property rights licensed to us, in which case
we would depend on the ability of our licensors to obtain, maintain and enforce intellectual property protection for the licensed intellectual property. These
licensors may determine not to pursue litigation against other companies or may pursue such litigation less aggressively than we would. Further, entering
into such license agreements could impose various diligence, commercialization, royalty, or other obligations on us. Future licensors may allege that we
have  breached  our  license  agreement  with  them,  and  accordingly  seek  to  terminate  our  license,  which  could  adversely  affect  our  competitive  business
position and harm our business prospects.

Epidemic diseases, or the perception of their effects, could have a material adverse effect on our business, financial condition, results of operations, or
cash flows.

Outbreaks of epidemic, pandemic, or contagious diseases, such as COVID-19, the recent novel coronavirus or, historically, the Ebola virus, Middle
East Respiratory Syndrome, Severe Acute Respiratory Syndrome, or the H1N1 virus, could divert medical resources and priorities towards the treatment of
that disease. An outbreak of a contagious disease, or continued escalation of the outbreak of the COVID-19, could also negatively affect hospital admission
rates  and  the  decision  by  patients  to  undergo  elective  surgery,  which  could  decrease  demand  for  procedures  using  our  iFuse  implants  and  cause  other
disruptions to our business. Business disruptions could include disruptions or restrictions on our ability to travel or to distribute our products, as well as
temporary closures of our facilities or the facilities of our suppliers and their contract manufacturers, and a reduction in the business hours of hospitals and
ambulatory surgery centers. Any disruption of our suppliers and their contract manufacturers or our customers would likely impact our sales and operating
results. In addition, a significant outbreak of epidemic, pandemic, or contagious diseases in the human population could result in a widespread health crisis
that could adversely affect the economies and financial markets of many countries, resulting in an economic downturn that could affect demand for our
products. Any of these events could negatively impact the number of procedures using our iFuse implants that are performed and have a material adverse
effect on our business, financial condition, results of operations, or cash flows.

38

Risks Related to Our Legal and Regulatory Environment

We,  our  suppliers,  and  our  third-party  manufacturers  are  subject  to  extensive  governmental  regulation  both  in  the  U.S.  and  abroad,  and  failure  to
comply with applicable requirements could cause our business to suffer.

The  medical  device  industry  is  regulated  extensively  by  governmental  authorities,  principally  the  FDA  and  corresponding  state  and  foreign

regulatory agencies. The FDA and other U.S. and foreign governmental agencies regulate, among other things, with respect to medical devices:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

design, development, and manufacturing;

testing, labeling, content, and language of instructions for use and storage;

clinical trials;

product safety;

marketing, sales, and distribution;

premarket clearance and approval;

conformity assessment procedures;

record keeping procedures;

advertising and promotion;

compliance with good manufacturing practices requirements;

recalls and field safety corrective actions;

post-market surveillance, including reporting of deaths or serious injuries and malfunctions that, if they were to recur, could lead to death or
serious injury;

post-market approval studies; and

product import and export.

The  regulations  to  which  we  are  subject  are  complex  and  have  tended  to  become  more  stringent  over  time.  Regulatory  changes  could  result  in
restrictions on our ability to carry on or expand our operations, difficulties achieving new product clearances, higher than anticipated costs or lower than
anticipated sales.

Before  we  can  market  or  sell  a  new  regulated  product  or  make  a  significant  modification  to  an  existing  product  in  the  U.S.,  with  only  limited
exceptions, we must obtain either clearance under Section 510(k) of the FDCA for Class II devices or approval of a PMA application from the FDA for a
Class III device. In the 510(k) clearance process, the FDA must determine that a proposed device is “substantially equivalent” to a device legally on the
market, known as a “predicate” device, with respect to intended use, technology, and safety and effectiveness, in order to clear the proposed device for
marketing. Clinical data is sometimes required to support substantial equivalence. The PMA pathway requires an applicant to demonstrate the safety and
effectiveness of the device based, in part, on extensive data, including, but not limited to, technical, pre-clinical, clinical trial, manufacturing, and labeling
data. The PMA process is typically required for devices that are deemed to pose the greatest risk, such as life-sustaining, life-supporting, or implantable
devices. Products that are approved through a PMA application generally need FDA approval before they can be modified. Similarly, some modifications
made to products cleared through a 510(k) may require a new 510(k). Both the 510(k) and PMA processes can be expensive and lengthy and require the
payment of significant fees, unless exempt. The FDA’s 510(k) clearance process usually takes from three to 12 months, but may last longer. The process of
obtaining a PMA is much more costly and uncertain than the 510(k) clearance process and generally takes from one to three years, or even longer, from the
time the application is submitted to the FDA until an approval is obtained. The process of obtaining domestic and international regulatory clearances or
approvals to market a medical device can be costly and time consuming, and we may not be able to obtain these clearances or approvals on a timely basis,
if at all.

In the U.S., our currently commercialized products have either received premarket clearance under Section 510(k) of the FDCA or are exempt from
premarket review. If the FDA requires us to go through a lengthier, more rigorous examination for future products or modifications to existing products
than we had expected, our product introductions or modifications could be delayed or canceled, which could cause our sales to decline. In addition, the
FDA  may  determine  that  future  products  will  require  the  more  costly,  lengthy,  and  uncertain  PMA  process.  Although  we  do  not  currently  market  any
devices under PMA, the FDA may demand that we obtain a PMA prior to marketing certain of our future products. In addition, if the FDA disagrees with
our determination that a product we currently market is subject to an exemption from premarket review, the FDA may require us to submit a 510(k) or
PMA  in  order  to  continue  marketing  the  product.  Further,  even  with  respect  to  those  future  products  where  a  PMA  is  not  required,  we  cannot  assure
investors that we will be able to obtain the 510(k) clearances with respect to those products.

39

 
The FDA can delay, limit or deny clearance or approval of a device for many reasons, including:

•

•

•

we may not be able to demonstrate to the FDA’s satisfaction that our products are safe and effective for their intended users;

the data from our pre-clinical studies and clinical trials may be insufficient to support clearance or approval, where required; and

the manufacturing process or facilities we use may not meet applicable requirements.

In addition, the FDA may change its clearance and approval policies, adopt additional regulations or revise existing regulations, or take other actions
which may prevent or delay clearance or approval of our products under development or impact our ability to modify our currently approved or cleared
products on a timely basis.

Any delay in, or failure to receive or maintain, clearance or approval for our products under development could prevent us from generating revenue

from these products or achieving profitability.

In addition, even after we have obtained the proper regulatory clearance or approval to market a product, the FDA has the power to require us to
conduct  post-marketing  studies.  These  studies  can  be  very  expensive  and  time  consuming  to  conduct.  Failure  to  comply  with  those  studies  in  a  timely
manner could result in the revocation of the 510(k) clearance for a product that is subject to such a 522 Order and the recall or withdrawal of the product,
which could prevent us from generating sales from that product in the U.S.

In the EEA, our medical devices must currently comply with the Essential Requirements set forth in Annex I to the EU Medical Devices Directive
(Council Directive 93/42/EEC), or Essential Requirements. Compliance with these requirements is a prerequisite to be able to affix the CE mark to our
medical devices, without which they cannot be marketed or sold in the EEA. To demonstrate compliance with the Essential Requirements we must undergo
a conformity assessment procedure, which varies according to the type of medical device and its classification. Except for low risk medical devices (Class
I),  where  the  manufacturer  can  issue  an  EC  Declaration  of  Conformity  based  on  a  self-assessment  of  the  conformity  of  its  products  with  the  Essential
Requirements, a conformity assessment procedure requires the intervention of a third-party organization designated by the competent authorities of a EEA
country  to  conduct  conformity  assessments,  known  as  a  Notified  Body.  The  Notified  Body  would  typically  audit  and  examine  the  medical  device’s
Technical File including the clinical evaluation, the quality system for the manufacture, design and conduct a final inspection of our medical devices before
issuing a CE Certificate of Conformity demonstrating compliance with the Essential Requirements or the QSR of the Medical Devices Directive.

As part of the conformity assessment process, medical device manufacturers must carry out a clinical evaluation of their medical devices to verify
that  they  comply  with  the  relevant  Essential  Requirements  covering  safety  and  performance.  A  clinical  evaluation  includes  an  assessment  of  whether  a
medical device’s performance is in accordance with its intended use and that the known and foreseeable risks linked to the use of the device under normal
conditions are minimized and acceptable when weighed against the benefits of its intended purpose. The clinical evaluation conducted by the manufacturer
must also address any clinical claims, the adequacy of the device labeling and information (particularly claims, contraindications, precautions/ warnings)
and the suitability of related Instructions for Use. This assessment must be based on clinical data, which can be obtained from (i) clinical studies conducted
on the devices being assessed; (ii) scientific literature from similar devices whose equivalence with the assessed device can be demonstrated; or (iii) both
clinical studies and scientific literature. With respect to implantable devices, or devices classified as Class III in the EU, the manufacturer must conduct
clinical  studies  to  obtain  the  required  clinical  data,  unless  the  relying  on  existing  clinical  data  from  similar  devices  can  be  justified.  As  part  of  the
conformity assessment procedure, depending on the type of devices, the Notified Body will review the manufacturer’s clinical evaluation for the medical
device. The conduct of clinical studies to obtain clinical data that might be required as part of the described clinical evaluation process can be expensive
and time consuming.

In May 2017, the EU Medical Device Regulation, (Regulation 2017/745) was adopted, as described in "Item 1. Business - Regulation - International

Regulation of Our Products".

The  FDA  and  other  regulatory  authorities,  including  foreign  authorities,  have  broad  enforcement  powers.  Regulatory  enforcement  or  inquiries,  or
other increased scrutiny on us, could dissuade some surgeons from using our products and adversely affect our reputation and the perceived safety and
effectiveness of our products.

Failure to comply with applicable regulations could jeopardize our ability to sell our products and result in enforcement actions such as:

•

•

•

•

warning letters;

fines;

injunctions;

civil penalties;

40

•

•

•

•

•

•

•

•

termination of distribution;

recalls or seizures of products;

delays in the introduction of products into the market;

total or partial suspension of production;

facility closures;

refusal of the FDA or our Notified Body or other regulator to grant future clearances or approvals or to issue CE Certificates of Conformity;

withdrawals, variation, or suspensions of current clearances or approvals and CE Certificates of Conformity, resulting in prohibitions on sales
of our products; and

in the most serious cases, criminal penalties.

Adverse action by an applicable regulatory agency, our Notified Body or the FDA could result in inability to produce our products in a cost-effective
and timely manner, or at all, decreased sales, higher prices, lower margins, additional unplanned costs or actions, damage to our reputation, and could have
material adverse effect on our reputation, business, results of operations, and financial condition.

We and our sales representatives must comply with U.S. federal and state fraud and abuse laws, including those relating to physician kickbacks and
false claims for reimbursement, as well as equivalent foreign laws.

Healthcare  providers,  distributors,  physicians,  and  third-party  payors  play  a  primary  role  in  the  distribution,  recommendation,  ordering,  and
purchasing of any implant or other medical device for which we have or obtain marketing clearance or approval. Through our arrangements with customers
and third-party payors, we are exposed to the risk that our employees, independent contractors, principal investigators, consultants, vendors, or third-party
distributors may engage in fraudulent or other illegal activity. Misconduct by these parties could include, among other infractions or violations, intentional,
reckless and/or negligent conduct or unauthorized activity that violates FDA regulations, manufacturing standards, federal and state healthcare fraud and
abuse laws and regulations, laws that require the true, complete, and accurate reporting of financial information or data, other commercial or regulatory
laws or requirements, and equivalent foreign rules. We have a compliance program, Code of Conduct, and associated policies and procedures, but it is not
always possible to identify and deter misconduct by our employees and other third parties, and the precautions we take to detect and prevent this activity
may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits
stemming from a failure to be in compliance with such laws or regulations, and government authorities may conclude that our business practices do not
comply with applicable fraud and abuse or other healthcare laws and regulations or guidance despite our good faith efforts to comply.

There  are  numerous  U.S.  federal  and  state  laws  pertaining  to  healthcare  fraud  and  abuse,  including  anti-kickback  and  false  claims  laws.  Our
relationships and our distributors’ relationships with surgeons, other healthcare professionals, and hospitals are subject to scrutiny under these laws. For
example,  we  are  subject  to  the  federal  health  care  Anti-Kickback  Statute,  the  federal  civil  False  Claims  Act,  the  Health  Insurance  Portability  and
Accountability Act ("HIPAA") and the federal Physician Payment Sunshine Act, each of which is described in detail in Item 1 Business - Healthcare Fraud
and Abuse” and “-Data Privacy and Security Laws”. 

Certain  states  also  mandate  implementation  of  corporate  compliance  programs,  require  compliance  with  the  industry’s  voluntary  compliance
guidelines,  impose  restrictions  on  device  manufacturer  marketing  practices,  and/or  require  tracking  and  reporting  of  gifts,  compensation,  and  other
remuneration to healthcare professionals and entities. analogous state and foreign 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 and patients; state laws
that require device companies to comply with the industry’s voluntary compliance guidelines and the applicable compliance guidance promulgated by the
federal  government  or  otherwise  restrict  payments  that  may  be  made  to  healthcare  providers  and  other  potential  referral  sources;  state  beneficiary
inducement laws, and state laws that require device manufacturers to report information related to payments and other transfers of value to physicians and
other healthcare providers or marketing expenditures, many of which differ from each other in significant ways and may not have the same effect, thus
complicating compliance efforts.

41

If we or our employees are found to have violated any of the above laws we may be subject to administrative, civil and criminal penalties, including
imprisonment, exclusion from participation in federal healthcare programs, such as Medicare, Medicaid, and equivalent foreign programs, significant fines,
monetary penalties and damages, imposition of compliance obligations and monitoring, the curtailment or restructuring of our operations, and damage to
our reputation.

We  have  entered  into  consulting  agreements  and  royalty  agreements  with  surgeons,  including  some  who  are  customers.  We  also  engage  in  co-
marketing arrangements with certain surgeons who use our products. In addition, a small number of our current customer surgeons own less than 1.0% of
our stock, which they either purchased in an arm’s length transaction on terms identical to those offered to others or received from us as fair market value
consideration for consulting services performed. While all of these transactions were structured with the intention of complying with all applicable laws,
including  the  federal  Anti-Kickback  Statute,  state  anti-kickback  laws  and  other  applicable  laws,  it  is  possible  that  regulatory  agencies  may  view  these
transactions as prohibited arrangements that must be restructured, or discontinued, or for which we could be subject to significant penalties and criminal,
civil and administrative liability. We would be materially and adversely affected if regulatory agencies interpret our financial relationships with surgeons
who order our products to be in violation of applicable laws and we were unable to comply with such laws, which could subject us to, among other things,
monetary penalties for non-compliance, the cost of which could be substantial.

In certain cases, federal, state and foreign authorities pursue actions for false claims on the basis that manufacturers and distributors are promoting
unapproved, or “off-label” uses of their products. Pursuant to FDA regulations, we can only market our products for cleared or approved uses. Although
surgeons are permitted to use medical devices for indications other than those cleared or approved by the FDA, we are prohibited from promoting products
for “off-label” uses. We market our products and provide promotional materials and training programs to surgeons regarding the use of our products. If it is
determined  that  our  marketing,  promotional  materials  or  training  programs  constitute  promotion  of  unapproved  uses,  we  could  be  subject  to  significant
fines  in  addition  to  regulatory  enforcement  actions,  including  the  issuance  of  a  warning  letter,  injunction,  seizure,  criminal  penalty,  and  damage  to  our
reputation. Federal, state and foreign authorities also pursue actions for false claims based upon improper billing and coding advice or recommendations, as
well as decisions related to the medical necessity of procedures, including the site-of-service where procedures are performed.

Various state and federal regulatory and enforcement agencies continue actively to investigate violations of health care laws and regulations, and the
U.S. Congress continues to strengthen the arsenal of enforcement tools. The Bipartisan Budget Act of 2018 increased the criminal and civil penalties that
can be imposed for violating certain federal health care laws, including the federal Anti- Kickback Statute. To enforce compliance with the federal laws, the
U.S. Department of Justice has increased its scrutiny of interactions between healthcare companies and healthcare providers, which has led to a number of
investigations, prosecutions, convictions and settlements in the healthcare industry. Dealing with investigations can be time- and resource-consuming and
can divert management’s attention from the business. Additionally, if a healthcare company settles an investigation with the Department of Justice or other
law enforcement agencies, it may need to agree to additional onerous compliance and reporting requirements as part of a consent decree, deferred or non-
prosecution agreement, or corporate integrity agreement. Any such investigation or settlement could increase our costs or otherwise have an adverse effect
on our business. Even if we are not determined to have violated these laws, government investigations into these issues typically require the expenditure of
significant resources and generate negative publicity, which could harm our financial condition and divert resources and the attention of our management
from operating our business.

The scope and enforcement of these laws is uncertain and subject to rapid change. The shifting compliance environment and the need to build and
maintain robust and expandable systems and processes to comply with different compliance and/or reporting requirements in multiple jurisdictions increase
the possibility that we may run afoul of one or more of the requirements or that federal or state regulatory authorities might challenge our current or future
activities under these laws. Additionally, we cannot predict the impact of any changes in these laws, whether or not retroactive.

42

Our failure to adequately protect personal information in compliance with evolving legal requirements could harm our business.

In the ordinary course of our business, we collect and store sensitive data, including legally protected personally identifiable information. We collect
this kind of information during the course of clinical trials and for post-marketing safety vigilance, helping enable surgeons and their patients to pursue
claims  for  reimbursement  for  procedures  using  iFuse  and  servicing  potential  warranty  claims.  In  doing  so,  we  are  subject  to  various  federal,  state  and
foreign laws that protect the confidentiality of certain patient health information, including patient medical records, and restrict the use and disclosure of
patient health information by healthcare providers, such as HIPAA, in the U.S. and regulations in the European Union ("EU"), which are described in detail
in Item 1 Business - Data Privacy and Security Laws”.

In June 2018, California enacted the California Consumer Privacy Act ("CCPA"). The CCPA, which became effective on January 1, 2020, requires a
broad  range  of  businesses  to  honor  the  requests  of  California  residents  to  access  and  require  deletion  of  their  personal  information,  opt  out  of  certain
personal  information  sharing,  and  receive  detailed  information  about  how  their  personal  information  is  used  and  shared.  The  CCPA  provides  for  civil
penalties of up to $7,500 for intentional violations, and a private right of action for data breaches that allows private plaintiffs to seek the greater of actual
damages or statutory damages of up to $750 per consumer per data breach.  These remedies are expected to increase data breach litigation.  The California
Attorney  General,  who  is  charged  with  interpreting  and  enforcing  the  law,  has  not  yet  promulgated  final  implementing  regulations,  and  considerable
uncertainty  as  to  how  the  law  will  be  implemented  and  enforced  remains. Although  the  CCPA  includes  exemptions  for  certain  clinical  trials  data,  and
protected  health  information  governed  by  HIPAA,  the  law  may  increase  our  compliance  costs  and  potential  liability  with  respect  to  other  personal
information  we  collect  about  California  residents.  The  CCPA  has  prompted  a  number  of  proposals  for  new  federal  and  state  privacy  legislation  that,  if
passed, could increase our potential liability, increase our compliance costs and adversely affect our business.

Our failure to comply with applicable laws and regulations, or to protect such data, could result in enforcement actions against us, including fines,
imprisonment  of  company  officials  and  public  censure,  claims  for  damages  by  end-customers,  and  other  affected  individuals,  and  the  imposition  of
integrity  obligations  and  agency  oversight,  damage  to  our  reputation,  and  loss  of  goodwill,  any  of  which  could  harm  on  our  operations,  financial
performance,  and  business.  Evolving  and  changing  definitions  of  personal  data  and  personal  information,  within  the  European  Union,  the  U.S.,  and
elsewhere, may limit or inhibit our ability to operate or expand our business, including limiting strategic partnerships that may involve the sharing of data.
Moreover, if the relevant laws and regulations change, or are interpreted and applied in a manner that is inconsistent with our data practices or the operation
of our products, or if we expand into new regions and are required to comply with new requirements, we may need to expend resources in order to change
our business operations, data practices, or the manner in which our products operate. Even the perception of privacy concerns, whether or not valid, may
harm our reputation and inhibit adoption of our products.

We are subject to risks associated with our non-U.S. operations.

The FCPA prohibits companies and their intermediaries from making improper payments to foreign officials for the purpose of obtaining or retaining
business. Other anti-corruption or anti-bribery laws, such as the UKBA, prohibit companies and their intermediaries from making improper payments for
the purpose of obtaining or retaining business in foreign countries. The FCPA also imposes accounting standards and requirements on publicly traded U.S.
corporations  and  their  foreign  affiliates,  which  are  intended  to  prevent  the  diversion  of  corporate  funds  to  the  payment  of  bribes  and  other  improper
payments, and to prevent the establishment of slush funds from which such improper payments can be made. Because of the predominance of government-
sponsored healthcare systems around the world, many of our customer relationships outside of the U.S. are with governmental entities and are therefore
subject to such anti-bribery laws. Our internal control policies and procedures may not always protect us from reckless or criminal acts committed by our
employees or agents. Violations of these laws, or allegations of such violations, could disrupt our operations, involve significant management distraction,
and  result  in  a  material  adverse  effect  on  our  business,  results  of  operations,  and  financial  condition.  We  also  could  suffer  severe  penalties,  including
criminal  and  civil  penalties,  disgorgement,  and  other  remedial  measures,  including  further  changes  or  enhancements  to  our  procedures,  policies,  and
controls, as well as potential personnel changes and disciplinary actions.

Furthermore, we are subject to anti-boycott laws, anti-money laundering laws, and the export controls and economic embargo rules and regulations
of the U.S., including, but not limited to, the Export Administration Regulations and trade sanctions against embargoed countries, which are administered
by  the  Office  of  Foreign  Assets  Control  within  the  Department  of  the  Treasury,  as  well  as  the  laws  and  regulations  administered  by  the  Department  of
Commerce.  These  regulations  limit  our  ability  to  market,  sell,  distribute,  or  otherwise  transfer  our  products  or  technology  to  prohibited  countries  or
persons.  A  determination  that  we  have  failed  to  comply,  whether  knowingly  or  inadvertently,  may  result  in  substantial  penalties,  including  fines  and
enforcement actions and civil and/or criminal sanctions, the disgorgement of profits, and the imposition of a court-appointed monitor, as well as the denial
of export privileges, and may have an adverse effect on our reputation.

43

 Even if our products are approved by regulatory authorities or CE marked, if we, our contractors, or our suppliers fail to comply with ongoing FDA or

other foreign regulatory requirements, or if we experience unanticipated problems with our products, these products could be subject to restrictions or
withdrawal from the market.

Any product for which we obtain regulatory clearance or approval, or a CE Certificate of Conformity, and the manufacturing processes, reporting
requirements, post-approval clinical data, and promotional activities for such product, will be subject to continued regulatory review, oversight and periodic
inspections by the FDA, our Notified Body and other domestic and foreign regulatory bodies. In particular, we and our suppliers are required to comply
with  FDA’s  Quality  System  Regulations  ("QSR"),  and  International  Standards  Organization,  regulations  for  the  manufacture  of  our  products  and  other
regulations  which  cover  the  methods  and  documentation  of  the  design,  testing,  production,  control,  quality  assurance,  labeling,  packaging,  storage,  and
shipping of any product for which we obtain regulatory clearance or approval, or a CE Certificate of Conformity.

The failure by us or one of our suppliers to comply with applicable statutes and regulations, or the failure to timely and adequately respond to any

adverse inspectional observations or product safety issues, could result in, among other things, any of the following enforcement actions:

•

•

•

•

•

•

•

•

•

•

•

•

untitled letters, warning letters, fines, injunctions, consent, and civil penalties;

unanticipated expenditures to address or defend such actions;

customer notifications for repair, replacement, refunds;

recall, detention, or seizure of our products;

operating restrictions or partial suspension or total shutdown of production;

refusing  or  delaying  our  requests  for  510(k)  clearance  or  premarket  approval  and  conformity  assessments  of  new  products  or  modified
products;

limitations on the intended uses for which the product may be marketed;

operating restrictions;

withdrawing 510(k) clearances or PMA approvals that have already been granted;

suspension, variation or withdrawal of CE Certificates of Conformity;

refusal to grant export approval for our products; and

criminal prosecution.

In addition, we are required to conduct costly post-market testing and surveillance to monitor the safety or effectiveness of our products, and we must
comply with medical device reporting requirements, including the reporting of adverse events and malfunctions related to our products. Later discovery of
previously  unknown  problems  with  our  products,  including  unanticipated  adverse  events  or  adverse  events  of  unanticipated  severity  or  frequency,
manufacturing problems, or failure to comply with regulatory requirements such as QSR, may result in changes to labeling, restrictions on such products or
manufacturing processes, withdrawal of the products from the market, voluntary or mandatory recalls, a requirement to repair, replace, or refund the cost of
any  medical  device  we  manufacture  or  distribute,  fines,  suspension,  variation,  or  withdrawal  of  regulatory  approvals  or  CE  Certificates  of  Conformity,
product seizures, injunctions, or the imposition of civil, administrative, or criminal penalties which would adversely affect our business, operating results,
and prospects.

If  the  FDA  determines  that  our  promotional  materials,  labeling,  training  or  other  marketing  or  educational  activities  constitute  promotion  of  an
unapproved use, it could request that we cease or modify our training or promotional materials or subject us to regulatory enforcement actions. It is also
possible  that  other  federal,  state  or  foreign  enforcement  authorities  might  take  action  if  they  consider  our  training  or  other  promotional  materials  to
constitute promotion of an unapproved use, which could result in significant fines or penalties under other statutory authorities, such as laws prohibiting
false or fraudulent claims for payment of government funds.

 If any of these actions were to occur it would harm our reputation and cause our product sales and profitability to suffer and may prevent us from

generating revenue. Furthermore, our key component suppliers may not currently be or may not continue to be in compliance with all applicable regulatory
requirements, which could result in our failure to produce our products on a timely basis and in the required quantities, if at all.

The FDA inspected our facilities in May 2014. As a result, we received a Notice of Inspectional Observations, or Form 483, with three observations
that  have  since  been  addressed  with  a  corrective  and  preventative  action  plan.  We  responded  to  the  Agency  in  writing  and  the  matter  was  closed  as  of
October 2014 through the issuance of an Establishment Inspection Report. To date, the FDA has not taken any further action with respect to the May 2014
inspection or its findings. The FDA inspected our facilities again in December 2016 and no findings were noted.

44

Our  employees,  independent  contractors,  consultants,  manufacturers,  and  third-party  distributors  may  engage  in  misconduct  or  other  improper
activities, relating to regulatory standards and requirements.

We  are  exposed  to  the  risk  that  our  employees,  independent  contractors,  consultants,  manufacturers,  and  third-party  distributors  may  engage  in
fraudulent  conduct  or  other  illegal  activity.  Misconduct  by  these  parties  could  include  intentional,  reckless  and/or  negligent  conduct  or  disclosure  of
unauthorized activities to us that violates FDA regulations, including those laws requiring the reporting of true, complete and accurate information to the
FDA, manufacturing standards, federal, state and foreign healthcare laws and regulations, data privacy laws, and laws that require the true, complete and
accurate reporting of financial information or data. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, marketing and
promotion, sales commission, customer incentive programs, and other business arrangements. Misconduct by these parties could also involve the improper
use  of  individually  identifiable  information,  including,  without  limitation,  information  obtained  in  the  course  of  clinical  trials,  which  could  result  in
regulatory sanctions and serious harm to our reputation. We have a compliance program, code of conduct and associated policies and procedures, but it is
not always possible to identify and deter misconduct, and the precautions we take to detect and prevent this activity may not be effective in controlling
unknown or unmanaged risks or losses or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to be in
compliance with such laws or 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 significant civil, criminal, and administrative penalties,
including,  without  limitation,  damages,  fines,  disgorgement  of  profits,  imprisonment,  exclusion  from  participation  in  government  healthcare  programs,
such as Medicare and Medicaid, and the curtailment or restructuring of our operations.

We may be subject to enforcement action, including fines, penalties or injunctions, if we are determined to be engaging in the off-label promotion of
our products.

Our promotional materials and training methods must comply with FDA and other applicable national and foreign laws and regulations, including the
prohibition of the promotion of off-label use. Physicians may use our products off-label, as the FDA and equivalent third country authorities do not restrict
or regulate a physician’s choice of treatment within the practice of medicine. In the U.S., the full indication for the iFuse Implant System is: “The iFuse
Implant System is intended for sacroiliac joint fusion for conditions including sacroiliac joint dysfunction that is a direct result of sacroiliac joint disruption
and degenerative sacroiliitis. This includes conditions whose symptoms began during pregnancy or in the peripartum period and have persisted postpartum
for more than six months. The iFuse Implant System is also intended for sacroiliac fusion to augment immobilization and stabilization of the sacroiliac
joint in skeletally mature patients undergoing sacropelvic fixation as part of a lumbar or thoracolumbar fusion” In the U.S., our marketing strategies must
adhere to the above statements. In all other countries, the indication statement for the iFuse Implant System (including iFuse-3D) more broadly indicates
that the device is indicated for sacroiliac joint fusion. The above-described potential limitation in indication statements in the U.S. does not apply in other
geographies.

 We believe that the specific surgical procedures for which our products are marketed fall within the scope of the surgical applications that have been

cleared  by  the  FDA  and  our  notified  body.  However,  if  the  FDA  or  an  equivalent  third  country  authority  determines  that  our  promotional  materials  or
training constitutes promotion of an off-label use, it could request that we modify our training or promotional materials, require us to stop promoting our
products  for  those  specific  procedures  until  we  obtain  FDA  or  third  country  authority  clearance  or  approval  for  them,  or  subject  us  to  regulatory  or
enforcement actions, including the issuance of an untitled letter, a warning letter, injunction, seizure, civil fines, and criminal penalties. It is also possible
that other federal, state or foreign enforcement authorities might take action if they consider our promotional or training materials to constitute promotion
of  an  unapproved  use,  which  could  result  in  significant  fines  or  penalties  under  other  statutory  authorities,  such  as  laws  prohibiting  false  or  fraudulent
claims for payment of government fund. In that event, our reputation could be damaged and adoption of the products would be impaired. Although our
policy is to refrain from statements that could be considered off-label promotion of our products, the FDA or another regulatory agency could disagree and
conclude that we have engaged in off-label promotion. In addition, the off-label use of our products may increase the risk of injury to patients, and, in turn,
the  risk  of  product  liability  claims.  Product  liability  claims  are  expensive  to  defend  and  could  divert  our  management’s  attention,  result  in  substantial
damage awards against us and harm our reputation.

We  are  required  to  report  certain  malfunctions,  deaths,  and  serious  injuries  associated  with  our  products,  which  can  result  in  voluntary  corrective
actions or agency enforcement actions.

Further, under the FDA’s medical device reporting, regulations, and equivalent rules of other countries, we are required to report to the FDA or a
similar  authority  in  such  other  country,  any  information  that  our  product  may  have  caused  or  contributed  to  a  death  or  serious  injury  or  in  which  our
product malfunctioned and, if the malfunction were to recur, would likely cause or contribute to death or serious injury. If we fail to report these events to
the FDA or applicable authority in another country within the required timeframes, or at all, FDA, or the applicable authority in the other country, could
take  enforcement  action  against  us.  Any  such  adverse  event  involving  our  products  or  repeated  product  malfunctions  may  result  in  a  voluntary  or
involuntary corrective actions, such as recalls or customer notifications, or agency action, such as inspection or enforcement action. Any corrective action,
whether  voluntary  or  involuntary,  as  well  as  defending  ourselves  in  a  lawsuit  could  divert  managerial  and  financial  resources,  impair  our  ability  to
manufacture our products in a cost-effective and timely manner, and have an adverse effect on our reputation, results of operations, and financial condition.

45

In the EEA, we must comply with the EU Medical Device Vigilance System. Under this system, incidents must be reported to the relevant authorities
of the Member States of the EEA, and manufacturers are required to take Field Safety Corrective Actions ("FSCAs"), to reduce a risk of death or serious
deterioration  in  the  state  of  health  associated  with  the  use  of  a  medical  device  that  is  already  placed  on  the  market.  An  incident  is  defined  as  any
malfunction  or  deterioration  in  the  characteristics  and/or  performance  of  a  device,  as  well  as  any  inadequacy  in  the  labeling  or  the  instructions  for  use
which, directly or indirectly, might lead to or might have led to the death of a patient or user or of other persons or to a serious deterioration in their state of
health.  An  FSCA  may  include  the  recall,  modification,  exchange,  destruction  or  retrofitting  of  the  device  FSCAs  must  be  communicated  by  the
manufacturer or its legal representative to its customers and/or to the end users of the device through Field Safety Notices. The entry into application in
May  2020  of  the  Medical  Device  Regulation  will  increase  the  obligation  that  we  must  fulfill  in  relation  to  vigilance  and  post-market  surveillance
obligations.

Any adverse event involving our products, whether in the U.S. or abroad could result in future voluntary corrective actions, such as recalls, including
corrections, or customer notifications, or agency action, such as inspection or enforcement actions. If malfunctions do occur, we may be unable to correct
the malfunctions adequately or prevent further malfunctions, in which case we may need to cease manufacture and distribution of the affected products,
initiate voluntary recalls, and redesign the products. Regulatory authorities may also take actions against us, such as ordering recalls, imposing fines, or
seizing  the  affected  products.  Any  corrective  action,  whether  voluntary  or  involuntary,  will  require  the  dedication  of  our  time  and  capital,  distract
management from operating our business, and may harm our reputation and financial results.

  A  recall  of  our  products,  either  voluntarily  or  at  the  direction  of  the  FDA  or  another  governmental  authority,  including  foreign  governmental

authorities,  or  the  discovery  of  serious  safety  issues  or  malfunctions  with  our  products,  can  result  in  voluntary  corrective  actions  or  agency
enforcement actions, which could have a significant adverse impact on us.

The FDA and similar foreign governmental authorities have the authority to require the recall of commercialized products in the event of material
deficiencies or defects in design or manufacture or in the event that a product poses an unacceptable risk to health. Manufacturers may, under their own
initiative, recall a product if any material deficiency in a device is found.

In the case of the FDA, the authority to require a recall must be based on an FDA finding that there is an unreasonable risk of substantial public
harm. In addition, foreign governmental bodies have the authority to require the recall of our products in the event of material deficiencies or defects in
design or manufacture. A government-mandated or voluntary recall by us or one of our third-party distributors could occur as a result of an unacceptable
risk to health, component failures, manufacturing errors, design or labeling defects, or other deficiencies and issues. Recalls of any of our products would
divert managerial and financial resources and have an adverse effect on our reputation, results of operations, and financial condition, which could impair
our ability to produce our products in a cost-effective and timely manner in order to meet our customers’ demands. We may also be required to bear other
costs or take other actions that may have a negative impact on our future sales and our ability to generate profits.

The  FDA  requires  that  certain  classifications  of  recalls  be  reported  to  FDA  within  10  working  days  after  the  recall  is  initiated.  Companies  are
required to maintain certain records of recalls, even if they are not reportable to the FDA. We may initiate voluntary recalls involving our products in the
future that we determine do not require notification of the FDA. If the FDA disagrees with our determinations, they could require us to report those actions
as  recalls.  A  future  recall  announcement  could  harm  our  reputation  with  customers  and  negatively  affect  our  sales.  In  addition,  the  FDA  could  take
enforcement action for failing to report the recalls when they were conducted. Equivalent procedures and penalties have been established in other countries
including EU Member States.

Modifications to our products may require new 510(k) clearances or premarket approvals and new conformity assessment by our Notified Body, or may
require us to cease marketing or recall the modified products until clearances, approvals, or CE Certificates of Conformity are obtained.

Any modification to a 510(k)-cleared device that could significantly affect its safety or effectiveness, or that would constitute a major change in its
intended use, design, or manufacture, requires a new 510(k) clearance or, possibly, a PMA. The FDA requires every manufacturer to make and document
this determination in the first instance. A manufacturer may determine that a modification could not significantly affect safety or effectiveness and does not
represent a major change in its intended use, so that no new 510(k) clearance is necessary. FDA may review any manufacturer’s decision and may not agree
with our decisions regarding whether new clearances or approvals are necessary. The FDA may also on its own initiative determine that a new clearance or
approval is required. We have made modifications to our products in the past and may 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  marketing  our  products  as  modified  until  clearance  or  approvals  can  be  obtained,  which  could  require  us  to  redesign  our
products and harm our operating results. In these circumstances, we may be subject to significant enforcement actions.

46

We have modified some of our 510(k) cleared products, and have determined based on our review of the applicable FDA guidance that in certain
instances new 510(k) clearances or PMAs are not required. If the FDA disagrees with our determination and requires us to submit new 510(k) clearances or
PMAs for modifications to our previously cleared products for which we have concluded that new clearances or approvals are unnecessary, we may be
required  to  cease  marketing  or  to  recall  the  modified  product  until  we  obtain  clearance  or  approval,  and  we  may  be  subject  to  significant  enforcement
action, regulatory fines, or penalties.

 If a manufacturer determines that a modification to an FDA-cleared device could significantly affect its safety or effectiveness, or would constitute a

major  change  in  its  intended  use,  then  the  manufacturer  must  file  for  a  new  510(k)  clearance  or  possibly  a  premarket  approval  application.  Where  we
determine  that  modifications  to  our  products  require  a  new  510(k)  clearance  or  premarket  approval  application,  we  may  not  be  able  to  obtain  those
additional clearances or approvals for the modifications or additional indications in a timely manner, or at all. FDA’s ongoing review of the 510(k) program
may make it more difficult for us to make modifications to our previously cleared products, either by imposing more strict requirements on when a new
510(k) for a modification to a previously cleared product must be submitted, or applying more onerous review criteria to such submissions.

In the EEA, we must inform the Notified Body that carried out the conformity assessment of the medical devices we market or sell in the EEA of any
planned  substantial  changes  to  our  quality  system,  manufacturing  process,  or  changes  to  our  devices  which  could  affect  compliance  with  the  essential
requirements or the devices’ intended use. The Notified Body will then assess the changes and verify whether they affect the products’ conformity with
Essential Requirements and related applicable laws. There can be no assurances that the assessment will be favorable and that the Notified Body will attest
our compliance with the essential requirements, which will prevent us from selling our products in the EEA. Moreover, any substantial changes that take
place  in  the  coming  years  may  impact  the  continuing  effectiveness  of  our  CE  Certificates  of  Conformity  that  were  issued  on  the  basis  of  the  Medical
Device Directive.

Obtaining regulatory clearances or approvals and CE Certificates of Conformity can be a time-consuming process, and delays in obtaining required
future regulatory clearances or approvals, and CE Certificates of Conformity would adversely affect our ability to introduce new or enhanced products in a
timely manner, which in turn would harm our future growth.

There is no guarantee that the FDA will grant 510(k) clearance or premarket approval of our future products or that our Notified Body will issue the
required  CE  Certificate  of  Conformity,  and  failure  to  obtain  necessary  clearances  or  approvals  for  our  future  products  would  adversely  affect  our
ability to grow our business.

We  are  in  the  process  of  developing  our  regulatory  strategies  for  obtaining  clearance  or  approval  for  future  products.  Some  of  them  may  require
510(k) clearance by the FDA or a new CE Certificate of Conformity. Other future products may require premarket approval. In addition, some of our new
products may require clinical trials to support regulatory approval and we may not successfully complete these clinical trials. The FDA may not approve or
clear  these  products  or  our  Notified  Body  may  not  issue  CE  Certificate  of  Conformity  for  the  indications  that  are  necessary  or  desirable  for  successful
commercialization.  Indeed,  the  FDA  may  refuse  our  requests  for  510(k)  clearance  or  premarket  approval  of  new  products,  new  intended  uses,  or
modifications to existing products and our Notified Body may refuse to issue new CE Certificates of Conformity. Failure to receive clearance, approval, or
Certificates of Conformity for our new products would have an adverse effect on our ability to expand our business.

We may fail to obtain or maintain foreign regulatory approvals to market our products in other countries.

We  currently  market  our  products  internationally  and  intend  to  expand  our  international  marketing.  International  jurisdictions  require  separate
regulatory  approvals  and  compliance  with  numerous  and  varying  regulatory  requirements.  For  example,  we  intend  to  continue  to  seek  domestic  and
international  regulatory  clearance  to  market  our  primary  products  Asia,  Latin  America,  and  the  Middle  East  and  other  key  markets.  The  approval
procedures vary among countries and may involve requirements for substantial additional testing, and the time required to obtain approval may differ from
country to country and from that required to obtain FDA clearance or approval or to obtain CE Certificates of Conformity.

Clearance or approval by the FDA or obtaining a CE Certificate of Conformity does not ensure approval or certification by regulatory authorities in
other  countries  or  jurisdictions,  and  approval  or  certification  by  one  foreign  regulatory  authority  does  not  ensure  approval  or  certification  by  regulatory
authorities  in  other  foreign  countries  or  by  the  FDA,  and  the  CE  marking  of  our  products  in  the  EEA.  The  foreign  regulatory  approval  or  certification
process may include all of the risks associated with obtaining FDA clearance or approval, or a CE Certificate of Conformity for a medical device in the
EEA in addition to other risks. In addition, the time required to obtain foreign approval may differ from that required to obtain FDA clearance or approval,
or a CE Certificate of Conformity in the EEA and we may not obtain foreign regulatory approvals on a timely basis, if at all. We may not be able to file for
regulatory approvals or certifications and may not receive necessary approvals to commercialize our products in any market. If we fail to receive necessary
approvals  or  certifications  to  commercialize  our  products  in  foreign  jurisdictions  on  a  timely  basis,  or  at  all,  our  business,  results  of  operations,  and
financial condition could be adversely affected.

47

Clinical  trials  necessary  to  support  a  510(k)  or  PMA  application  or  a  conformity  assessment  procedure  will  be  expensive  and  may  require  the
enrollment  of  large  numbers  of  patients,  and  suitable  patients  may  be  difficult  to  identify  and  recruit.  Delays  or  failures  in  our  clinical  trials  will
prevent us from commercializing any modified or new products, or new indications for use for existing products, and will adversely affect our business,
operating results and prospects.

Initiating and completing clinical trials necessary to support a PMA application for our future products and additional safety and effectiveness data
beyond that typically required for a 510(k) clearance for iFuse, as well as other possible future product candidates, and to support a conformity assessment
procedure to support a new CE Certificate of Conformity would be time consuming and expensive and the outcome uncertain. Moreover, the results of
early clinical trials are not necessarily predictive of future results, and any product, or new indication for use, we advance into clinical trials may not have
favorable results in later clinical trials.

Conducting successful clinical studies may require the enrollment of large numbers of patients, and suitable patients may be difficult to identify and
recruit. Patient enrollment in clinical trials and completion of patient participation and follow-up depends on many factors, including the size of the patient
population, the nature of the trial protocol, the attractiveness of, or the discomforts and risks associated with, the treatments received by enrolled subjects,
the availability of appropriate clinical trial investigators, support staff, and proximity of patients to clinical sites and able to comply with the inclusion and
exclusion criteria for participation in the clinical trial and patient compliance. Development of sufficient and appropriate clinical protocols to demonstrate
safety  and  effectiveness  are  required  and  we  may  not  adequately  develop  such  protocols  to  support  clearance  and  approval.  Further,  the  FDA  or  our
Notified Body may require us to submit data on a greater number of patients than we originally anticipated and/or for a longer follow-up period or change
the data collection requirements or data analysis applicable to our clinical trials. Delays in patient enrollment or failure of patients to continue to participate
in a clinical trial may cause an increase in costs and delays in the approval and attempted commercialization of our products or result in the failure of the
clinical trial. In addition, despite considerable time and expense invested in our clinical trials, the FDA or our Notified Body may not consider our data
adequate  to  demonstrate  safety  and  effectiveness.  Such  increased  costs  and  delays  or  failures  could  adversely  affect  our  business,  operating  results  and
prospects.

Our  facility  and  our  clinical  investigational  sites  operate  under  procedures  that  govern  the  conduct  and  management  of  FDA-regulated  clinical
studies under 21 CFR Parts 50 and 812, and Good Clinical Practices. The FDA may conduct Bioresearch Monitoring inspections of us and/or our clinical
sites  to  assess  compliance  with  21  CFR  Parts  50  and  812,  our  procedures,  and  the  clinical  protocol.  If  the  FDA  were  to  find  that  we  or  our  clinical
investigators are not operating in compliance with applicable regulations, we could be subject to the above FDA enforcement action, as well as refusal to
accept all or part of our data in support of our 510(k) or PMA, or we may need to conduct additional studies.

The results of our clinical trials may not support our product candidate claims or may result in the discovery of adverse side effects.

Even if our clinical trials are completed as planned, we cannot be certain that their results will support our product candidate claims or that the FDA,
foreign authorities, or our Notified Body will agree with our conclusions regarding them. Success in pre-clinical studies and early clinical trials does not
ensure that later clinical trials will be successful, and we cannot be sure that the later trials will replicate the results of prior trials and pre-clinical studies.
The clinical trial process may fail to demonstrate that our product candidates are safe and effective for the proposed indicated uses, which could cause us to
abandon  a  product  candidate  and  may  delay  development  of  others.  Any  delay  or  termination  of  our  clinical  trials  will  delay  the  filing  of  our  product
submissions and, ultimately, our ability to commercialize our product candidates and generate revenue. It is also possible that patients enrolled in clinical
trials will experience adverse side effects that are not currently part of the product candidate’s profile.

U.S. legislative or FDA or foreign regulatory reforms may make it more difficult and costly for us to obtain regulatory clearances or approvals, or CE
Certificates of Conformity for our product candidates and to manufacture, market, and distribute our products after approval is obtained.

From  time  to  time,  Congress  introduces  legislation  that  could  significantly  change  the  statutory  provisions  governing  the  regulatory  approval,
manufacture,  and  marketing  of  regulated  products  or  the  reimbursement  thereof.  In  addition,  FDA  regulations  and  guidance  are  often  revised  or
reinterpreted by the FDA in ways that may significantly affect our business and our products. Moreover, the new Medical Device Regulation will enter into
application on May 26, 2020. Any new regulations or revisions or reinterpretations of existing regulations may impose additional costs or lengthen review
times of future products. In addition, FDA regulations and guidance are often revised or reinterpreted by the agency in ways that may significantly affect
our  business  and  our  products.  It  is  impossible  to  predict  whether  legislative  changes  will  be  enacted  or  FDA  regulations,  guidance,  or  interpretations
changed, and what the impact of such changes, if any, may be.

48

In  December  2016,  the  21st  Century  Cures  Act  was  enacted,  with  a  number  of  provisions  impacting  medical  device  regulation.  The  FDA  has
implemented, and continues to implement, these reforms, which could impose additional regulatory requirements upon us and delay our ability to obtain
new 510(k) clearances, increase the costs of compliance or restrict our ability to maintain our current clearances. Any change in the laws or regulations that
govern  the  clearance  and  approval  processes  relating  to  our  current  and  future  products  could  make  it  more  difficult  and  costly  to  obtain  clearance  or
approval for new products, or to produce, market, and distribute existing products. Significant delays in receiving clearance or approval, or the failure to
receive clearance or approval for our new products would have an adverse effect on our ability to expand our business.

Leadership,  personnel  and  structural  changes  within  the  FDA  as  well  as  recent  and  impending  federal  election  outcomes,  including  the  2020
presidential election, could result in significant legislative and regulatory reforms impacting the FDA's regulation of our products. Any change in the laws
or regulations that govern the clearance and approval processes relating to our current and future products could make it more difficult and costly to obtain
clearance or approval for new products, or to produce, market and distribute existing products. Significant delays in receiving clearance or approval, or the
failure to receive clearance or approval for our new products would have an adverse effect on our ability to expand our business.

Another example can be found in the EEA. The Medical Devices Regulation became effective on May 25, 2017. Following its entry into application
on  May  26,  2020,  the  Medical  Devices  Regulation  will  introduce  substantial  changes  to  the  obligations  with  which  medical  device  manufacturers  must
comply in the EEA. High risk medical devices will be subject to additional scrutiny during the conformity assessment procedure. Specifically, the Medical
Devices Regulation repeals and replaces the EU Medical Devices Directive. Unlike directives, which must be implemented into the national laws of the
EEA Member States, regulations are directly applicable, i.e., without the need for adoption of national legislation in EEA Member States implementing
them. The purpose of regulations is to eliminate current differences in regulation of medical devices among EEA Member States. The Medical Devices
Regulation,  among  other  things,  is  intended  to  establish  a  uniform,  transparent,  predictable  and  sustainable  regulatory  framework  across  the  EEA  for
medical  devices  to  ensure  a  high  level  of  safety  and  health  while  supporting  innovation.  These  regulations  will  substantially  impact  medical  devices
manufacturers. Examples of the changes which will be introduced by these regulations include the following:

•

•

•

•

•

•

•

•

additional scrutiny during the conformity assessment procedure for high risk medical devices;

strengthening of the clinical data requirements related to medical devices;

strengthening of the designation and monitoring processes governing notified bodies;

the  obligation  for  manufacturers  and  authorized  representative  to  have  a  person  responsible  for  regulatory  compliance  continuously  at  their
disposal;

authorized representatives would be held legally responsible and liable for defective products placed on the EU market;

increased traceability of medical devices following the introduction of a Unique Device Identification ("UDI"), system;

new rules governing the reprocessing of medical devices; and

increased transparency with the establishment of EUDAMED III as information from several databases concerning economic operators, CE
Certificates  of  Conformity,  conformity  assessment,  clinical  investigations,  the  UDI  system,  adverse  event  reporting  and  market  surveillance
would be available to the public.

The Medical Device Regulation substantially amplifies the provisions of the Medical Device Directive governing clinical investigations of medical
devices.  Among  others,  it  imposes  specific  obligations  concerning  incapacitated  subjects,  minors,  pregnant  or  breastfeeding  women  and  clinical
investigations in emergency situations. In addition to detailed provisions concerning the authorization and conduct of clinical investigations, the Regulation
imposes on non-EU sponsors a responsibility to appoint a legal representative established in the EU and an obligation on EU Member States to ensure that
systems for compensation for any damage suffered by a subject resulting from participation in a clinical investigation conducted on their territory are in
place and on sponsors and investigators the obligation to ensure they make use of these make use of these systems.

Transition from the regulation of our products under the current Medical Device Directive, and implementing legislation in each EU Member State, to
regulation  under  the  Medical  Devices  Regulation  may  require  a  substantial  transition  effort  by  us.  In  addition,  detail  as  to  how  certain  aspects  of  the
Medical Devices Regulation will be applied remains unclear. Failure to update our quality system and regulatory documentation could delay our transition
to  compliance  with  the  Medical  Devices  Regulation  and  delay  or  prevent  us  from  obtaining  new  CE  Certificates  of  Conformity  under  the  Regulation.
Transition from compliance with the Medical Device Directive to the Medical Devices Regulation could result in disruption to our business in the EEA
which could adversely affect our business, results of operation and financial condition. In addition, any changes to the membership of the European Union,
such as the departure of the United Kingdom from the EU, may impact the regulatory requirements for the impacted countries and impair our business
operations and our ability to market products in such countries.

49

 
The  sales  of  our  products  depend  in  part  on  the  availability  of  coverage  and  reimbursement  from  third-party  payors  such  as  government  health
administration authorities, private health insurers, health maintenance organizations, and other healthcare-related organizations. Recent political, economic,
and  regulatory  influences  are  subjecting  the  healthcare  industry  to  fundamental  changes  that  can  impact  coverage  and  reimbursement  from  third-party
payors. For example, Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2011, among other
things, reduced and/or limited Medicare reimbursement to certain providers. Legislative changes to the Patient Protection and Affordable Care Act remain
possible  in  the  116th  U.S.  Congress  and  under  the  Trump  Administration.  We  expect  that  the  Patient  Protection  and  Affordable  Care  Act,  as  currently
enacted or as it may be amended in the future, and other healthcare reform measures that may be adopted in the future, could have a material adverse effect
on our industry generally and on our ability to maintain or increase sales of our existing products. Other federal laws further reduce Medicare’s payments to
providers by two percent through 2024. These reductions reduce reimbursement for our products, which could potentially negatively impact our revenue,
and may reduce providers’ revenues or profits, which could affect their ability to purchase new technologies. Both the federal and state governments in the
U.S.  and  foreign  governments  continue  to  propose  and  pass  new  legislation  and  regulations  designed  to  contain  or  reduce  the  cost  of  healthcare.  Such
legislation and regulations may result in decreased reimbursement for medical devices, which may further exacerbate industry-wide pressure to reduce the
prices charged for medical devices. This could harm our ability to market our products and generate sales.

We may incur product liability losses, and insurance coverage may be inadequate or unavailable to cover these losses.

Our  business  exposes  us  to  potential  product  liability  claims  that  are  inherent  in  the  testing,  design,  manufacture,  and  sale  of  surgical  devices.
Sacroiliac joint and other orthopedic spine surgeries involve significant risk of serious complications, including bleeding, nerve injury, paralysis, and even
death.  In  addition,  if  longer-term  patient  results  and  experience  indicates  that  our  products  or  any  component  of  a  product  cause  tissue  damage,  motor
impairment, or other adverse effects, we could be subject to significant liability. Surgeons may misuse or ineffectively use our products, which may result
in  unsatisfactory  patient  outcomes  or  patient  injury.  We  could  become  the  subject  of  product  liability  lawsuits  alleging  that  component  failures,
manufacturing  flaws,  design  defects,  or  inadequate  disclosure  of  product-related  risks  or  product-related  information  resulted  in  an  unsafe  condition  or
injury to patients. Product liability lawsuits and claims, safety alerts, or product recalls, regardless of their ultimate outcome, could have a material adverse
effect on our business and reputation, our ability to attract and retain customers and our results of operations or financial condition.

Although we maintain third-party product liability insurance coverage, it is possible that claims against us may exceed the coverage limits of our
insurance policies or cause us to record a self-insured loss. Even if any product liability loss is covered by an insurance policy, these policies typically have
substantial retentions or deductibles that we are responsible for. Product liability claims in excess of applicable insurance coverage could have a material
adverse effect on our business, results of operations, and financial condition.

In addition, any product liability claim brought against us, with or without merit, could result in an increase of our product liability insurance rates.
Insurance coverage varies in cost and can be difficult to obtain, and we cannot guarantee that we will be able to obtain insurance coverage in the future on
terms acceptable to us or at all.

We are subject to environmental laws and regulations that can impose significant costs and expose us to potential financial liabilities.

The manufacture of certain of our products, including our implants and products, and the handling of materials used in the product testing process,
including in our cadaveric laboratory, involve the use of biological, hazardous and/or radioactive materials and wastes. Our business and facilities and those
of  our  suppliers  are  subject  to  foreign,  federal,  state,  and  local  laws  and  regulations  relating  to  the  protection  of  human  health  and  the  environment,
including those governing the use, manufacture, storage, handling, and disposal of, and exposure to, such materials and wastes. In addition, under some
environmental laws and regulations, we could be held responsible for costs relating to any contamination at our past or present facilities and at third-party
waste disposal sites even if such contamination was not caused by us. A failure to comply with current or future environmental laws and regulations could
result  in  severe  fines  or  penalties.  Any  such  expenses  or  liability  could  have  a  significant  negative  impact  on  our  business,  results  of  operations,  and
financial condition.

The comprehensive tax reform bill adopted in 2017 could adversely affect our business and financial condition.

On December 22, 2017, President Trump signed into law new legislation that significantly revised the Internal Revenue Code of 1986, as amended,
or the Code. The newly enacted federal income tax law, among other things, contains significant changes to corporate taxation, including reduction of the
corporate tax rate from a top marginal rate of 35% to a flat rate of 21%, limitation of the tax deduction for interest expense to 30% of adjusted earnings
(except  for  certain  small  businesses),  limitation  of  the  deduction  for  net  operating  losses  arising  after  2017  to  80%  of  current  year  taxable  income  and
elimination of carrybacks of such net operating losses, one time taxation of offshore earnings at reduced rates regardless of whether they are repatriated,
elimination  of  U.S.  tax  on  foreign  earnings  (subject  to  certain  important  exceptions),  immediate  deductions  for  certain  new  investments  instead  of
deductions for depreciation expense over time, and modification or repeal of many business deductions and credits. Notwithstanding the reduction in the
corporate income tax rate, the overall impact of the new federal tax law is uncertain and our business and financial condition could be adversely affected. In
addition, it is uncertain if and to what extent various states will conform to the newly enacted federal tax law. The impact of this tax

50

reform on holders of our common stock is also uncertain and could be adverse. We urge our stockholders to consult with their legal and tax advisors with
respect to this legislation and the potential tax consequences of investing in or holding our common stock.

The UK’s withdrawal from the EU and uncertainty regarding tariffs affecting U.S. imports and exports may have a negative effect on global economic
conditions, financial markets and our business.

On January 31, 2020, the UK withdrew from the EU. Brexit has created significant uncertainty concerning the future relationship between the UK
and the EU. In light of the fact that a significant portion of the regulatory framework in the UK is derived from EU laws, Brexit could materially impact the
regulatory regime with respect to the development, manufacture, importation, approval and commercialization of our product in the UK or the EU. Any
changes in our manufacturing or commercialization activities as a result of Brexit, could increase our costs and otherwise adversely affect our business. In
addition, currency exchange rates for the British Pound and the euro with respect to each other and to the U.S. dollar have already been, and may continue
to be, negatively affected by Brexit, which could cause volatility in our quarterly financial results.

We do not know to what extent, or when, the UK’s withdrawal from the EU or any other future changes to membership in the EU will impact our
business,  particularly  our  ability  to  conduct  international  business  from  a  base  of  operations  in  the  UK.  The  UK  could  lose  the  benefits  of  global  trade
agreements negotiated by the EU on behalf of its members, possibly resulting in increased trade barriers, which could make doing business in Europe more
difficult and/or costly. Moreover, in the U.S., tariffs on certain U.S. imports have recently been imposed, and the EU and other countries have responded
with retaliatory tariffs on certain U.S. exports. We cannot predict what effects these and potential additional tariffs will have on our business, including in
the context of escalating global trade and political tensions. However, these tariffs and other trade restrictions, whether resulting from the UK’s withdrawal
from  the  EU  or  otherwise,  could  increase  our  cost  of  doing  business,  reduce  our  gross  margins  or  otherwise  negatively  impact  our  business  and  our
financial results.

Risks Related to Our Intellectual Property

If  we  or  our  licensors  fail  to  adequately  protect  or  enforce  our  intellectual  property  rights  or  secure  rights  to  patents  of  others,  the  value  of  our
intellectual property rights would diminish and our ability to successfully commercialize our products may be impaired.

We rely primarily on patent, copyright, trademark and trade secret laws, as well as confidentiality and non- disclosure agreements and other methods,
to  protect  our  proprietary  technologies  and  know-how.  As  of  December  31,  2019,  we  owned  40  issued  U.S.  patents  and  had  19  pending  U.S.  patent
applications, and we owned 10 issued foreign patents and had 5 pending foreign patent applications. We have focused the majority of our foreign patent
efforts in China, Europe, and Japan. Our current U.S. patents on iFuse, including the triangular shape, expire in August 2024. Our current U.S. patents on
iFuse 3D, including the fenestrated design, expire in September 2035. Our foreign patents will expire between August 2025 and October 2031. Competitors
may  market  similar  triangular  shaped  devices  upon  the  expiration  of  the  patents  in  2024.  We  will  continue  to  have  patent  protection  of  our  3D-printed
fenestrated implants through 2035.

As of December 31, 2019, we have 14 registered trademarks in the U.S. and have filed for 4 more. We have sought protection for at least 2 of these

trademarks in 60 countries including the 28 European member countries of the Madrid Protocol.

We have applied for patent protection relating to certain existing and proposed products and processes. While we generally apply for patents in those
countries where we intend to make, have made, use, or sell patented products, we may not accurately predict all of the countries where patent protection
will  ultimately  be  desirable.  If  we  fail  to  timely  file  a  patent  application  in  any  such  country,  we  may  be  precluded  from  doing  so  at  a  later  date.
Furthermore,  we  cannot  assure  investors  that  any  of  our  patent  applications  will  be  approved.  The  rights  granted  to  us  under  our  patents,  including
prospective rights sought in our pending patent applications, may not be meaningful or provide us with any commercial advantage. In addition, those rights
could be opposed, contested, or circumvented by our competitors or be declared invalid or unenforceable in judicial or administrative proceedings. The
failure of our patents to adequately protect our technology might make it easier for our competitors to offer the same or similar products or technologies.
Competitors may be able to design around our patents or develop products that provide outcomes that are comparable to ours without infringing on our
intellectual property rights. Due to differences between foreign and U.S. patent laws, our patented intellectual property rights may not receive the same
degree of protection in foreign countries as they would in the U.S. Even if patents are granted outside the U.S., effective enforcement in those countries
may  not  be  available.  Since  most  of  our  issued  patents  are  for  the  U.S.  only,  we  lack  a  corresponding  scope  of  patent  protection  in  other  countries.  In
countries where we do not have significant patent protection, we may not be able to stop a competitor from marketing products in such countries that are
the same as or similar to our products.

We rely on our trademarks, trade names and brand names to distinguish our products from the products of our competitors and have registered or
applied to register many of these trademarks. We cannot assure investors that our trademark applications will be approved. Third parties may also oppose
our trademark applications, or otherwise challenge our use of the trademarks. In the event that our trademarks are successfully challenged, we could be
forced to rebrand our products, which could result in loss of brand recognition, and could require us to devote resources to advertising and marketing new
brands. Further, we cannot assure investors that competitors

51

will not infringe upon our trademarks, or that we will have adequate resources to enforce our trademarks.

We also rely on trade secrets, know-how, and technology, which are not protected by patents, to maintain our competitive position. We try to protect
this  information  by  entering  into  confidentiality  and  intellectual  property  assignment  agreements  with  parties  that  develop  intellectual  property  for  us
and/or  have  access  to  it,  such  as  our  officers,  employees,  consultants,  and  advisors.  However,  in  the  event  of  unauthorized  use  or  disclosure  or  other
breaches of such agreements, we may not be provided with meaningful protection for our trade secrets or other proprietary information. In addition, our
trade  secrets  may  otherwise  become  known  or  be  independently  discovered  by  competitors.  To  the  extent  that  our  commercial  partners,  collaborators,
employees, and consultants use intellectual property owned by others in their work for us, disputes may arise as to the rights in related or resulting know-
how  and  inventions.  If  any  of  our  trade  secrets,  know-how  or  other  technologies  not  protected  by  a  patent  were  to  be  disclosed  to  or  independently
developed by a competitor, our business, financial condition, and results of operations could be materially adversely affected.

In the future, we may enter into licensing agreements to maintain our competitive position. If we enter into in-bound intellectual property license
agreements, we may not be able to fully protect the licensed intellectual property rights or maintain those licenses. Future licensors could retain the right to
prosecute and defend the intellectual property rights licensed to us, in which case we would depend on the ability of our licensors to obtain, maintain and
enforce  intellectual  property  protection  for  the  licensed  intellectual  property.  These  licensors  may  determine  not  to  pursue  litigation  against  other
companies or may pursue such litigation less aggressively than we would. Further, entering into such license agreements could impose various diligence,
commercialization, royalty, or other obligations on us. Future licensors may allege that we have breached our license agreement with them, and accordingly
seek damages or to terminate our license, which could adversely affect our competitive business position and harm our business prospects.

If  a  competitor  infringes  upon  one  of  our  patents,  trademarks,  or  other  intellectual  property  rights,  enforcing  those  patents,  trademarks,  and  other
rights  may  be  difficult  and  time  consuming.  Even  if  successful,  litigation  to  defend  our  patents  and  trademarks  against  challenges  or  to  enforce  our
intellectual property rights could be expensive and time consuming and could divert management’s attention from managing our business. Moreover, we
may not have sufficient resources to defend our patents or trademarks against challenges or to enforce our intellectual property rights. In addition, if third
parties infringe any intellectual property that is not material to the products that we make, have made, use, or sell, it may be impractical for us to enforce
this intellectual property against those third parties.

We may be subject to damages resulting from claims that we, our employees, or our third-party distributors have wrongfully used or disclosed alleged
trade secrets of our competitors or are in breach of non-competition or non-solicitation agreements with our competitors.

Many of our employees were previously employed at other medical device companies, including our competitors or potential competitors, in some
cases until recently. Some of our third-party distributors sell, or in the past have sold, products of our competitors. We may be subject to claims that we, our
employees, or our third-party distributors have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of these former
employers or competitors. In addition, we have been and may in the future be subject to claims that we caused an employee to breach the terms of his or
her non-competition or non-solicitation agreement. Even if we are successful in defending against these claims, litigation could result in substantial costs,
divert the attention of management from our core business and harm our reputation. If our defense to those claims fails, in addition to paying monetary
damages, we may lose valuable intellectual property rights or personnel. There can be no assurance that this type of litigation will not continue, and any
future litigation or the threat thereof may adversely affect our ability to hire additional direct sales representatives. A loss of key personnel or their work
product could hamper or prevent our ability to commercialize product candidates, which could have an adverse effect on our business, results of operations,
and financial condition.

52

The medical device industry is characterized by patent litigation and we could become subject to litigation that could be costly, result in the diversion of
management’s time and efforts, require us to pay damages, and/or prevent us from developing or marketing our existing or future products.

Our commercial success will depend in part on not infringing the patents or violating the other proprietary rights of third parties. Significant litigation
regarding patent rights exists in our industry. Our competitors in both the U.S. and abroad, many of which have substantially greater resources and have
made  substantial  investments  in  competing  technologies,  may  have  applied  for  or  obtained  or  may  in  the  future  apply  for  and  obtain,  patents  that  will
prevent, limit, or otherwise interfere with our ability to make and sell our products. We have conducted a limited review of patents issued to third parties.
The large number of patents, the rapid rate of new patent issuances, the complexities of the technology involved, and the uncertainty of litigation increase
the risk of business assets and management’s attention being diverted to patent litigation. Any litigation or claim against us, even those without merit, may
cause  us  to  incur  substantial  costs,  and  could  place  a  significant  strain  on  our  financial  resources,  divert  the  attention  of  management  from  our  core
business,  and  harm  our  reputation.  Further,  as  the  number  of  participants  in  the  medical  device  industry  grows,  the  possibility  of  intellectual  property
infringement claims against us increases. If we are found to infringe the intellectual property rights of third parties, we could be required to pay substantial
damages, including treble, or triple, damages if an infringement is found to be willful, and/or royalties and could be prevented from selling our products
unless we obtain a license or are able to redesign our products to avoid infringement. Any such license may not be available on reasonable terms, if at all,
and there can be no assurance that we would be able to redesign our products in a way that would not infringe the intellectual property rights of others. If
we fail to obtain any required licenses or make any necessary changes to our products or technologies, we may have to withdraw existing products from the
market  or  may  be  unable  to  commercialize  one  or  more  of  our  products,  all  of  which  could  have  a  material  adverse  effect  on  our  business,  results  of
operations, and financial condition. If passed into law, patent reform legislation currently pending in the U.S. Congress could significantly change the risks
associated with bringing or defending a patent infringement lawsuit. For example, fee shifting legislation could require a non-prevailing party to pay the
attorney fees of the prevailing party in some circumstances.

In addition, we generally indemnify our customers and third-party distributors with respect to infringement by our products of the proprietary rights
of third parties. Third parties may assert infringement claims against our customers or third-party distributors. These claims may require us to initiate or
defend protracted and costly litigation on behalf of our customers or third-party distributors, regardless of the merits of these claims. If any of these claims
succeed,  we  may  be  forced  to  pay  damages  on  behalf  of  our  customers  or  third-party  distributors  or  may  be  required  to  obtain  licenses  to  intellectual
property  owned  by  such  third  parties.  If  we  cannot  obtain  all  necessary  licenses  on  commercially  reasonable  terms,  our  customers  and  third-party
distributors may be forced to stop using or selling our products.

Risks Related to Ownership of Our Common Stock

The price of our common stock may be volatile, and the value of an investment in our common stock could decline.

Medical  device  stocks  have  historically  experienced  volatility,  and  the  trading  price  of  our  common  stock  may  fluctuate  substantially.  These
fluctuations could cause our stockholders to lose all or part of their investment in our common stock. Factors that could cause fluctuations in the trading
price of our common stock include the following:

•

•

•

•

•

•

•

•

•

•

•

•

•

actual or anticipated changes or fluctuations in our results of operations;

results of our clinical trials and that of our competitors’ products;

regulatory actions with respect to our products or our competitor’s products;

announcements  of  new  offerings,  products,  services  or  technologies,  commercial  relationships,  acquisitions,  or  other  events  by  us  or  our
competitors;

price and volume fluctuations in the overall stock market from time to time;

significant  volatility  in  the  market  price  and  trading  volume  of  healthcare  companies,  in  general,  and  of  companies  in  the  medical  device
industry in particular;

fluctuations in the trading volume of our shares or the size of our public float;

negative publicity;

whether our results of operations meet the expectations of securities analysts or investors or those expectations change;

litigation involving us, our industry, or both;

regulatory developments in the U.S., foreign countries, or both;

lock-up releases and sales of large blocks of our common stock;

additions or departures of key employees or scientific personnel; and

53

 
•

general economic conditions and trends.

In  addition,  if  the  market  for  healthcare  stocks  or  the  stock  market,  in  general,  experience  a  loss  of  investor  confidence,  the  trading  price  of  our
common stock could decline for reasons unrelated to our business, results of operations, or financial condition. The trading price of our common stock
might  also  decline  in  reaction  to  events  that  affect  other  companies  in  our  industry  even  if  these  events  do  not  directly  affect  us.  In  the  past,  following
periods of volatility in the market price of a company’s securities, securities class action litigation has often been brought against that company. If our stock
price  is  volatile,  we  may  become  the  target  of  securities  litigation.  Securities  litigation  could  result  in  substantial  costs  and  divert  our  management’s
attention and resources from our business. This could have a material adverse effect on our business, results of operations, and financial condition.

Our sales volumes and our operating results may fluctuate over the course of the year, which could affect the price of our common stock.

We have experienced and continue to experience meaningful variability in our sales and gross profit from quarter to quarter, as well as within each

quarter. Our sales and results of operations will be affected by numerous factors, including, among other things:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

payor coverage and reimbursement;

the number of products sold in the quarter and our ability to drive increased sales of our products;

our ability to establish and maintain an effective and dedicated sales force;

pricing pressure applicable to our products, including adverse third-party coverage and reimbursement outcomes;

results of clinical research and trials on our existing products and products in development;

the mix of our products sold because profit margins differ amongst our products;

timing of new product offerings, acquisitions, licenses or other significant events by us or our competitors;

the ability of our suppliers to timely provide us with an adequate supply of materials and components;

the evolving product offerings of our competitors;

the demand for, and pricing of, our products and the products of our competitors;

factors that may affect the sale of our products, including seasonality and budgets of our customers;

domestic and international regulatory clearances or approvals, or CE Certificates of Conformity, and legislative changes affecting the products
we may offer or those of our competitors;

interruption in the manufacturing or distribution of our products;

the effect of competing technological, industry and market developments;

our ability to expand the geographic reach of our sales and marketing efforts;

the costs of maintaining adequate insurance coverage, including product liability insurance;

the availability and cost of components and materials;

the number of selling days in the quarter;

fluctuation in foreign currency exchange rates; and

impairment and other special charges.

Some of the products we may seek to develop and introduce in the future will require FDA clearance or approval before commercialization in the
U.S., and commercialization of such products outside of the U.S. would likely require additional regulatory approvals, or Certificates of Conformity and
import licenses. As a result, it will be difficult for us to forecast demand for these products with any degree of certainty. In addition, we will be increasing
our operating expenses as we expand our commercial capabilities. Accordingly, we may experience significant, unanticipated losses. If our quarterly or
annual  operating  results  fall  below  the  expectations  of  investors  or  securities  analysts,  the  price  of  our  common  stock  could  decline  substantially.
Furthermore,  any  quarterly  or  annual  fluctuations  in  our  operating  results  may,  in  turn,  cause  the  price  of  our  common  stock  to  fluctuate  substantially.
Quarterly comparisons of our financial results may not always be meaningful and should not be relied upon as an indication of our future performance.

54

 
We may be unable to utilize our federal net operating loss carryforwards to reduce our income taxes.

As of December 31, 2019, we had net operating loss ("NOL") carryforwards of $164.4 million and $129.6 million available to reduce future taxable
income, if any, for U.S. federal income tax and state income tax purposes, respectively. If not utilized, our federal and state NOL carryforwards begin to
expire in 2028 and 2020, respectively. These NOL carryforwards could expire unused and be unavailable to offset future income tax liabilities. In addition,
under Section 382 of the Code, and corresponding provisions of state law, if a corporation undergoes an “ownership change,” which generally occurs if the
percentage of the corporation’s stock owned by 5% stockholders increases by more than 50% over a three-year period, the corporation’s ability to use its
pre-change  NOL  carryforwards  and  other  pre-change  tax  attributes  to  offset  its  post-change  income  may  be  limited.  We  have  determined  that  we  have
experienced Section 382 ownership changes in 2010 and $1.4 million of our NOL and tax credit carryforwards are subject to limitation. We also updated
our Section 382 ownership change analysis through June 30, 2019, considering the recent changes in ownership following our IPO in October 2018. Based
on  the  result  of  the  analysis,  we  concluded  that  we  did  not  undergo  ownership  change  that  would  require  for  any  additional  limitations  on  our  NOL
carryforwards. We further concluded that the equity shift between June 30, 2019 to December 31, 2019 was not material, considering the changes in the
outstanding number of shares at each respective periods. We will continually assess the need to update our Section 382 ownership change analysis, as we
may experience ownership changes in the future that could materially limit our ability to use our NOL carryforwards, which may harm our future operating
results by effectively increasing our future tax obligations.

We  do  not  intend  to  pay  dividends  for  the  foreseeable  future  and,  consequently,  our  stockholders'  ability  to  achieve  a  return  on  investment  in  our
common stock will depend on appreciation in the price of our common stock.

We have never declared or paid any dividends on our common stock. We intend to retain any earnings to finance the operation and expansion of our
business, and we do not anticipate paying any cash dividends in the future. As a result, our stockholders may only receive a return on an investment in our
common stock if the market price of our common stock increases. In addition, our loan and security agreements contain restrictions on our ability to pay
dividends.

Our credit facility contains covenants that may restrict our business and financing activities.

Borrowings under our credit facility are secured by substantially all of our assets. Our credit facility also restricts our ability to, among other things:

•

•

•

•

•

•

•

•

•

•

dispose of or sell assets;

make material changes in our business or management;

consolidate or merge with or acquire other entities;

incur additional indebtedness;

incur liens on our assets;

pay dividends or make distributions on our capital stock;

make certain investments;

enter into transactions with our affiliates;

make any payment in respect of any subordinated indebtedness; and

waive or amend any of our current intellectual property agreements or material contracts.

 These restrictions are subject to certain exceptions. In addition, our loan and security agreement requires us to maintain a minimum cash balance and

revenue targets. Beginning with the three months ended March 31, 2019, we are required to meet either revenue or earnings targets.

The  covenants  in  our  credit  facility,  as  well  as  any  future  financing  agreements  that  we  may  enter  into,  may  restrict  our  ability  to  finance  our
operations, engage in, expand, or otherwise pursue our business activities and strategies. Our ability to comply with these covenants may be affected by
events beyond our control, and future breaches of any of these covenants could result in a default under our credit facility agreements. If not waived, future
defaults  could  cause  all  of  the  outstanding  indebtedness  under  our  credit  facility  agreement  to  become  immediately  due  and  payable  and  terminate  all
commitments to extend further credit.

If we do not have or are unable to generate sufficient cash available to repay our debt obligations when they become due and payable, either upon
maturity or in the event of a default, we may not be able to obtain additional debt or equity financing on favorable terms, if at all, which may negatively
impact our ability to operate our business.

55

Our charter documents and Delaware law could discourage takeover attempts and lead to management entrenchment.

Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could delay or prevent a change in
control of our company. These provisions could also make it difficult for stockholders to elect directors that are not nominated by the current members of
our board of directors or take other corporate actions, including effecting changes in our management. These provisions include:

•

•

•

•

•

•

•

a classified board of directors with three-year staggered terms, which could delay the ability of stockholders to change the membership of a
majority of our board of directors;

the  ability  of  our  board  of  directors  to  issue  shares  of  preferred  stock  and  to  determine  the  price  and  other  terms  of  those  shares,  including
preferences and voting rights, without stockholder approval, which could be used to significantly dilute the ownership of a hostile acquiror;

the  exclusive  right  of  our  board  of  directors  to  elect  a  director  to  fill  a  vacancy  created  by  the  expansion  of  our  board  of  directors  or  the
resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on our board of directors;

a  prohibition  on  stockholder  action  by  written  consent,  which  forces  stockholder  action  to  be  taken  at  an  annual  or  special  meeting  of  our
stockholders;

the requirement that a special meeting of stockholders may be called only by a majority vote of our entire board of directors, the chairman of
our board of directors, or our chief executive officer, which could delay the ability of our stockholders to force consideration of a proposal or to
take action, including the removal of directors;

the requirement for the affirmative vote of holders of at least 66 2/3% of the voting power of all of the then-outstanding shares of the voting
stock,  voting  together  as  a  single  class,  to  amend  the  provisions  of  our  amended  and  restated  certificate  of  incorporation  relating  to  the
management of our business or our amended and restated bylaws, which may inhibit the ability of an acquiror to effect such amendments to
facilitate an unsolicited takeover attempt; and

advance notice procedures with which stockholders must comply to nominate candidates to our board of directors or to propose matters to be
acted upon at a stockholders’ meeting, which may discourage or deter a potential acquiror from conducting a solicitation of proxies to elect the
acquiror’s own slate of directors or otherwise attempting to obtain control of us.

 In addition, as a Delaware corporation, we are subject to Section 203 of the Delaware General Corporation Law. These provisions may prohibit large

stockholders, in particular those owning 15% or more of our outstanding voting stock, from merging or combining with us for a certain period of time.

A  Delaware  corporation  may  opt  out  of  this  provision  by  express  provision  in  its  original  certificate  of  incorporation  or  by  amendment  to  its
certificate  of  incorporation  or  bylaws  approved  by  its  stockholders.  However,  we  have  not  opted  out  of,  and  do  not  currently  intend  to  opt  out  of,  this
provision.

These and other provisions in our amended and restated certificate of incorporation, amended and restated bylaws and Delaware law could make it
more difficult for stockholders or potential acquirers to obtain control of our board of directors or initiate actions that are opposed by our then-current board
of directors, including delay or impede a merger, tender offer, or proxy contest involving our company. The existence of these provisions could negatively
affect the price of our common stock and limit opportunities for our stockholders to realize value in a corporate transaction.

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware and the U.S. federal district courts
are  the  exclusive  forums  for  substantially  all  disputes  between  us  and  our  stockholders,  which  restricts  our  stockholders’  ability  to  bring  a  lawsuit
against us or our directors, officers, or employees in jurisdictions other than Delaware and federal district courts.

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for any
derivative action or proceeding brought on our behalf; any action asserting a breach of a fiduciary duty; any action asserting a claim against us arising
pursuant  to  the  Delaware  General  Corporation  Law,  our  amended  and  restated  certificate  of  incorporation,  or  our  amended  and  restated  bylaws;  or  any
action asserting a claim against us that is governed by the internal affairs doctrine. The provision would not apply to suits brought to enforce a duty or
liability created by the Exchange Act. This choice of forum provision may limit a stockholder's ability to bring a claim in a judicial forum that it finds
favorable for these types of disputes with us or our directors, officers, or other employees.

56

Our  amended  and  restated  certificate  of  incorporation  also  provides  that  the  U.S.  federal  district  courts  are  the  exclusive  forum  for  resolving  any
complaint asserting a cause of action arising under the Securities Act. However, in light of a Delaware Chancery Court opinion issued in December 2018,
we announced that we currently do not intend to enforce this aspect of our forum selection clause.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

Our  leased  headquarters  in  Santa  Clara,  California,  comprises  approximately  21,848  square  feet.  Our  headquarters  houses  our  research,  product
development, marketing, finance, education, and administration functions. We believe our facilities are adequate and suitable for our current needs but in
the future we may need additional space. We  also  lease  office  spaces  in  Gallarate,  Italy,  Mannheim,  Germany  and  Knaresborough,  United  Kingdom  to
accommodate our European sales and marketing team.

Item 3. Legal Proceedings

On February 6, 2019, a putative class action captioned Eric B. Fromer Chiropractic, Inc. ("Plaintiff") v. SI-BONE, Inc. (Civil Action No. 5:19-cv-
633-SVK), was filed in the U.S. District Court, Northern District of California. The complaint alleges violations of the Telephone Consumer Protection Act
(the “TCPA”) on behalf of an individual and a putative class of persons alleged to be similarly situated. The complaint alleges that we sent invitations to an
educational  dinner  event  to  health  care  providers  by  way  of  facsimile  transmission.  The  TCPA  prohibits  using  a  fax  machine  to  send  unsolicited
advertisements not including proper opt-out instructions or to send unsolicited advertisements to persons with whom the sender did not have an established
business relationship. The plaintiff sought various forms of relief, including statutory damages of $500 for each violation of the TCPA or, in the alternative,
treble damages of up to $1,500 for each knowing and willful violation of the TCPA and a permanent injunction prohibiting us from sending or having sent
advertisements by way of facsimile transmission. On December 23, 2019 the parties filed a joint stipulation of dismissal of the case in the District Court in
the Northern District of California and on January 14, 2020, the parties executed a definitive settlement agreement (the "Settlement Agreement"), pursuant
to which, we agreed to settle all disputes regarding the advertising faxes to the settlement class.

As this lawsuit is being resolved through a negotiated settlement and class resolution process, we believe that we will incur a loss associated with
resolution  of  the  claims  against  us.  We  accrued  a  litigation  expense  of  $3.2  million  during  the  year  ended  December  31,  2019  within  general  and
administrative  expenses  in  the  consolidated  financial  statements.  The  accrual  reflects  the  estimable  and  probable  costs  that  we  may  incur  based  on
estimated claims submitted by members of the settlement class, as defined in the Settlement Agreement. The final disposition of the lawsuit may result in a
loss in excess of the aggregate recorded amount.

We have never declared or paid any cash dividends on our capital stock, and we do not currently intend to pay any cash dividends on our capital stock

in the foreseeable future.

Recent Sales of Unregistered Securities

There were no sales of unregistered equity securities during the three months ended December 31, 2019.

Purchases of Equity Securities by the Issuer and Affiliated Purchasers

There were no repurchases of shares or equity securities during the three months ended December 31, 2019.

Use of Proceeds from our Initial Public Offering of Common Stock

On October 16, 2018, our registration statement on Form S-1 (File No. 333-227445) relating to our initial public offering ("IPO") of common stock
became effective. The IPO closed on October 16, 2018 at which time we issued 8,280,000 shares of our common stock at an initial offering price of $15.00
per share for gross proceeds of $124.2 million. We received net proceeds from the IPO of approximately $113.4 million, after deducting the underwriting
discount of $8.7 million and other offering-related expenses of $2.1 million. None of the expenses associated with our IPO were paid to directors, officers,
persons owning 10% or more of any class of equity securities, or to their associates, or to our affiliates.

There has been no material change in the planned use of proceeds from the IPO from that described in the prospectus filed with the SEC pursuant to
Rule 424(b)(4) under the Securities Act on October 16, 2018. As of December 31, 2019, approximately $39.5 million of the net proceeds had been used for
general corporate purposes including cash used in operations and capital expenditures.

The  following  discussion  and  analysis  of  our  financial  condition  and  results  of  operations  should  be  read  in  conjunction  with  our  financial
statements and the related notes to those statements included elsewhere in this Annual Report on Form 10-K. Some of the information contained in this
discussion and analysis or set forth elsewhere in this Annual Report on Form 10-K, including information with respect to our plans and strategy for our
business, includes forward-looking statements that involve risks and uncertainties. As a result of many important factors, including those set forth in the
"Risk Factors" section of this Annual Report on Form 10-K, our actual results could differ materially from the results described in, or implied, by these
forward-looking statements.

Overview

We are a medical device company focused on the development of implantable devices used in the surgical treatment of the sacropelvic anatomy. We
have  pioneered  a  proprietary  minimally  invasive  surgical  implant  system,  which  we  call  iFuse,  to  fuse  the  sacroiliac  joint  to  treat  sacroiliac  joint
dysfunction, which often causes severe lower back pain. Since we introduced iFuse in 2009, as of December 31, 2019, more than 44,000 procedures have
been performed by over 2,000 surgeons, in the U.S. and 35 other countries.

We  introduced  our  second-generation  implant,  the  iFuse-3D,  in  2017.  This  patented  titanium  implant  combines  the  triangular  cross-section  of  our

first-generation iFuse Implant with a proprietary 3D-printed porous surface and fenestrated design.

In April 2019, we received clearance from the U.S. Food and Drug Administration ("FDA"), to promote the use of our iFuse system with the iFuse
Bedrock  technique  for  fusion  of  the  sacroiliac  joint  in  conjunction  with  multi-level  spinal  fusion  procedures  to  provide  further  stabilization  and
immobilization  of  the  sacroiliac  joint.  We  received  CE  marking  and  began  marketing  our  iFuse  system  for  the  same  indication  in  Europe  in  December
2019.

We market our products primarily with a direct sales force as well as a number of distributors in the U.S., and with a combination of a direct sales

force and distributors in other countries.

In October 2018, we completed our initial public offering ("IPO") by issuing 8,280,000 shares of common stock, at an offering price of $15.00 per
share, for net proceeds of $113.4 million after deducting underwriting discounts and commissions and offering expenses payable by us. In January 2020,
we  received  $50.3 million  of  net  proceeds,  after  deducting  the  underwriting  discounts  and  commissions  but  before  offering  expenses,  from  our  public
offering of 4,300,000 shares of our common stock, of which 2,490,053 shares were offered and sold by us. Further, in February 2020, the underwriters fully
exercised its option to purchase 645,000 shares of our common stock at a public offering price of $21.50 per share for an additional net proceeds of $13.0
million to us, after deducting the underwriting discounts and commissions. For more information regarding this subsequent public offering, refer to Item 8.
Financial Statements and Supplementary Data, “Note 14 - Subsequent Events” in the accompanying Notes to Consolidated Financial Statements.

Factors Affecting Results of Operations and Key Performance Indicators

We monitor certain key performance indicators that we believe provides us and our investors indications of conditions that may affect results of our
operations. Our revenue growth rate and commercial progress is impacted by, among others, our key performance indicators including our ability to expand
our sales force, increase surgeon activity, engage key opinion leaders and influence coverage and reimbursements.

Expanding our sales force

We made significant investments in our sales force. As of December 31, 2019, our U.S. sales force consisted of 56 territory sales managers directly
employed  by  us  and  37  third-party  distributors,  compared  to  45  territory  sales  managers  directly  employed  by  us  and  30  third-party  distributors  as  of
December 31, 2018. As of December 31, 2019, our international sales force consisted of 19 sales representatives directly employed by us and 27 exclusive
third-party distributors, compared to 14 sales representatives directly employed by us and 23 exclusive third-party distributors as of December 31, 2018.
We anticipate continuing to build our operations in the major European countries while establishing distributor arrangements in smaller ones. We believe
that our expanded field organization allows us to reach more surgeons, educating them to include the sacroiliac joint in their differential diagnosis of lower
back pain and to regularly perform the iFuse procedure for patients for whom the procedure is indicated.

59

Increasing surgeon activity

We grew our active surgeon base to 539 surgeons as of December 31, 2019, compared to 450 active surgeons as of December 31, 2018. We define an
active surgeon to be a surgeon who has performed at least one case in the last three months. The increase in active surgeons is primarily due to training of
additional surgeons throughout the year. We have several surgeon trainer consultants who train new surgeons, focusing on diagnosis and treatment. As of
December 31, 2019, approximately 1,400 surgeons in the U.S. have been trained on iFuse and have treated at least one patient. We will continue to pursue
the remainder of the approximately 7,500 target surgeons in the U.S. for training in the future.

Engaging key opinion leaders

We  conduct  training  courses  in  several  academic  centers  in  the  U.S.  We  are  seeing  interest  from  key  opinion  leaders  at  academic  centers  in  our
Bedrock  technique.  We  introduced  this  technique  in  June  2019  for  use  in  the  fusion  of  the  sacroiliac  joints  in  conjunction  with  a  multi-segment  spinal
fusion,  or  long  construct,  procedure.  The  Bedrock  technique  is  based  on  our  proprietary  implants  and  is  used  to  increase  stability  at  the  base  of  a  long
construct.  Biomechanical  data  shows  that  placing  iFuse  implants  with  the  Bedrock  technique  reduces  sacroiliac  joint  motion  by  approximately  30%  in
conjunction  with  a  long  construct.  Interest  in  the  Bedrock  technique  has  enabled  our  field  sales  representatives  to  access  leading  spine  surgeons  at
important academic medical centers in the U.S. Our representatives are often then able to train a broader group of spine surgeons, including residents and
fellows in training at the centers, on both the Bedrock technique and minimally invasive sacroiliac fusion. We recently received CE mark clearance for the
promotion of the Bedrock technique in Europe and we are now in the process of launching the promotion of this technique in select European markets. We
believe that acceptance of the sacroiliac joint as a pain generator by leading spine surgeons may result in more widespread awareness of sacroiliac joint
dysfunction and its role in causing certain types of chronic low back pain.

Influencing coverage and reimbursement

We made progress in 2019 in both the number of covered lives and the Medicare physician fee for surgeons performing minimally invasive sacroiliac

fusion in the U.S.

• Covered lives - As of December 31, 2019, of the U.S. payors covering 282.7 million lives that reimburse for iFuse, 147.9 million lives are covered
by private payors, compared to 256.2 million covered lives, of which 121.7 million were covered by private payors as of December 31, 2018. We
track the number of U.S. covered lives, or individuals whose healthcare is paid for by a private commercial or governmental payor that routinely
reimburses for minimally invasive sacroiliac fusion, as a proxy for availability of the procedure within the U.S. healthcare payment system. As of
December 31, 2019, 32 private payors have issued positive coverage policies exclusive to iFuse for sacroiliac joint fusion because of the clinical
evidence, compared to 26 exclusive coverage policies as of December 31, 2018. These payors have based their exclusive coverage decisions on
the quality of our data. Further, as of December 31, 2019 and 2018, 20 and 19, respectively, private payors are covering iFuse and other products
for sacroiliac joint fusion. We believe that the full impact of each coverage decision grows over time as surgeons gain confidence that they will
receive reimbursement for the majority of their diagnosed patients.

• Surgeon  payment  -  The  Center  for  Medicare  &  Medicaid  Services  ("CMS")  announced  in  November  2019  that  the  U.S.  national  average
physician  fee  reimbursement  for  minimally  invasive  sacroiliac  joint  fusion  increased  from  $720,  effective  January  1,  2019  to  $915,  effective
January 1, 2020. Many private payors set their payment amounts with reference to the Medicare payment, often approximately 10% to 33% higher
than  the  Medicare  payment  for  a  procedure.  We  believe  that  expanded  coverage  for  minimally  invasive  sacroiliac  fusion  and  the  increase  in
physician reimbursement for the procedure may enable surgeons to treat more patients diagnosed with sacroiliac joint dysfunction with iFuse.

Components of Results of Operations

Revenue

We generate our revenue from sales of iFuse. Revenue from sales of iFuse fluctuate based on volume of cases (procedures performed), discounts, mix
of international and U.S. sales, mix of Bedrock and lateral sacroiliac fusions, and the number of implants used for a particular patient. Similar to other
orthopedic companies, our case volume can vary from quarter to quarter due to a variety of factors including reimbursement, sales force changes, physician
activities, and seasonality. In addition, our revenue is impacted by changes in average selling price as we respond to the competitive landscape. Further,
revenue results can differ based upon the mix of business between U.S. and international sales and mix of our products either delivered at the point of
implantation at the hospital or other medical facilities or delivered through distributors or to hospitals where the products were ordered in advance of the
procedure.  Our  revenue  from  international  sales  is  impacted  by  fluctuations  in  foreign  currency  exchange  rates  between  the  U.S.  dollar  (our  reporting
currency) and the local currency.

Cost of Goods Sold, Gross Profit, and Gross Margin

We  utilize  third-party  manufacturers  for  production  of  iFuse  implants  and  instrument  sets.  Cost  of  goods  sold  consists  primarily  of  costs  of  the
components of iFuse implants and instruments, instrument set depreciation, scrap and inventory obsolescence, as well as distribution-related expenses such
as logistics and shipping costs. We anticipate that our cost of goods sold will increase as case levels increase.

Our gross profit and gross margin have been and will continue to be affected by factors impacting revenue and cost of goods sold. In addition, our
gross margins are typically higher on products we sell directly as compared to products we sell through third-party distributors. As a result, changes in the
mix of direct versus distributor sales can directly influence our gross margins.

Operating Expenses

Our operating expenses consist of sales and marketing, research and development, and general and administrative expenses. Personnel costs are the
most  significant  component  of  operating  expenses  and  consist  of  salaries,  sales  commissions  and  other  cash  and  stock-based  compensation  related
expenses. We expect operating expenses to increase as we continue to invest and grow our business.

Sales and Marketing Expenses

Sales and marketing expenses primarily consist of salaries, stock-based compensation expense, and other compensation related costs, for personnel
employed  in  sales,  marketing,  medical  affairs,  reimbursement  and  professional  education  departments.  In  addition,  our  sales  and  marketing  expenses
include  commissions  and  bonuses,  generally  based  on  a  percentage  of  sales,  to  our  senior  sales  management,  direct  territory  sales  managers,  territory
associate representatives and third-party distributors. We expect our sales and marketing expenses to increase with the continued commercialization of our
current and future products and continued investment in our global sales organization, including broadening our relationships with third-party distributors,
expanding exclusivity commitments among them and increasing the number of our direct sales representatives, especially with increased reimbursement
and adoption in the U.S. Our sales and marketing expenses may fluctuate from period to period due to the seasonality of our business and as we continue to
add direct territory sales managers in new territories.

Research and Development Expenses

Our research and development expenses primarily consist of engineering, product development, clinical and regulatory expenses (including clinical
study expenses), and consulting services, outside prototyping services, outside research activities, materials, depreciation, and other costs associated with
development  of  our  products.  Research  and  development  expenses  also  include  related  personnel  and  consultants’  compensation  and  stock-based
compensation expense. We expense research and development costs as they are incurred. We expect research and development expense to increase as we
develop  new  products,  add  research  and  development  personnel,  and  undergo  clinical  activities,  including  more  clinical  studies  to  gain  additional
regulatory clearances and wider surgeon adoption.

General and Administrative Expenses

General and administrative expenses primarily consist of salaries, stock-based compensation expense, and other costs for finance, accounting, legal,
compliance,  and  administrative  matters.  We  expect  our  general  and  administrative  expenses  to  increase  to  support  the  growth  of  our  business.  We  also
expect to incur additional general and administrative expenses as a result of operating as a public company, including but not limited to: expenses related to
compliance with the rules and regulations of the Securities and Exchange Commission and those of the Nasdaq Global Market on which our securities are
traded; additional insurance expenses; investor relations activities; and other administrative and professional services.

Interest Income

Interest income is primarily related to our investments of excess cash in money market funds and marketable securities.

Interest Expense

Interest expense is primarily related to borrowings and amortization of debt issuance costs. Prior to our initial public offering, interest expense also

included the amortization of debt discounts derived from the issuance of warrants.

Other Income (Expense), Net

Other income (expense), net consists primarily of net foreign exchange gains (losses) on foreign transactions. Prior to our initial public offering, other
income  (expense),  net  included  changes  in  fair  value  of  our  preferred  stock  warrant  liability.  In  connection  with  our  IPO,  our  preferred  stock  warrant
liability was reclassified to equity upon conversion of preferred stock warrants to common stock warrants.

Revenue. Revenue increased $11.9 million, or 22%, for the year ended December 31, 2019 compared to the year ended December 31, 2018. This is
primarily due to an increase of $11.7 million from growth of U.S. revenue due to the hiring of more sales force and training of new surgeons resulting to
increased  case  volumes.  Our  international  sales  also  increased  $0.2  million  for  the  year  ended  December  31,  2019  compared  to  the  year  ended
December 31, 2018 mainly due to increased case volumes.

Cost of Goods Sold, Gross Profit, and Gross Margin. Total cost of goods sold increased $2.0 million, or 40%, for the year ended December 31, 2019
compared to the year ended December 31, 2018. The increase was primarily due to higher sales volumes. Higher net revenue resulted in increased gross
profit of $10.0 million, or 20%. Gross margin decreased to 90% for the year ended December 31, 2019 as compared to 91% the year ended December 31,
2018 due to an increase in personnel in operations to support the growth of the business.

Sales and Marketing Expenses. Sales and marketing expenses increased $23.8 million, or 53%, for the year ended December 31, 2019 as compared
to the year ended December 31, 2018. The increase  was  primarily  due  to  an  increase  of  $8.6  million  in  salaries  and  other  employee  related  costs,  $2.5
million in travel expense, and $1.8 million in facilities and other related expenses as a result of an increase in headcount, $5.5 million in commissions due
to increased sales, $2.7 million in stock-based compensation expense due to increase in headcount and issuance of stock grants with higher market value,
and  $2.7  million  in  training,  advertising  and  marketing  costs  due  to  continued  commercialization  of  our  current  and  future  products  and  continued
investment in our global sales organization.

Research and Development Expenses. Research and development expenses increased $1.9 million, or 35%, for the year ended December 31, 2019 as
compared to the year ended December 31, 2018. The increase was primarily due to an increase of $0.9 million in salaries and other employee related costs,
$0.4  million  in  stock-based  compensation  expense,  and  $0.6  million  in  facilities  and  other  related  expenses  from  increased  research  and  development
activities as well as higher headcount.

General and Administrative Expenses. General and administrative expenses increased $8.3 million, or 66%, for the year ended December 31, 2019 as
compared to the year ended December 31, 2018. The increase was primarily due to $3.2 million of accrued litigation expense in 2019, and increases of $0.8
million in salaries and employee related costs due to increases in headcount, $2.0 million in stock-based compensation from an increase in headcount and
issuance of stock grants with higher market value, $1.3 million in consulting and professional services due to additional regulatory and other compliance
services required for a public company, and $1.0 million in facilities and other expenses due to expansion of our general and administrative department.

Interest Income. Interest income increased $1.8 million for the year ended December 31, 2019 as compared to the year ended December 31, 2018,
mainly  as  a  result  of  full  year  investments  in  marketable  securities  during  the  year  ended  December  31,  2019  compared  to  partial  year  investments  in
marketable securities during the year ended December 31, 2018, following the IPO.

Interest  Expense.  Interest  expense  remained  relatively  unchanged  for  the  year  ended  December  31,  2019  as  compared  to  the  year  ended

December 31, 2018.

Other  Expense,  Net.  Other  expense,  net,  decreased  by  $1.1  million  for  the  year  ended  December  31,  2019  as  compared  to  the  year  ended
December 31, 2018, primarily due to the change in fair value of preferred stock warrant liability of $0.8 million recognized in the year ended December 31,
2018, and lower foreign currency exchange losses.

Liquidity and Capital Resources

As of December  31,  2019,  we  had  cash  and  marketable  securities  of  $93.1 million compared to $122.2 million  as  of  December  31,  2018.  Since
inception, we have financed our operations through our initial public offering, private placements of preferred stock, debt financing arrangements, and the
sale  of  our  products.  In  January  and  February  2020,  we  received  a  total  of  $63.4  million  of  net  proceeds  after  deducting  underwriting  discounts  and
commissions but before offering expenses, from a follow-on public offering of our common stock, including the underwriters' full exercise its option to
purchase  additional  shares  of  our  common  stock.  For  more  information  regarding  subsequent  public  offering,  refer  to  Item  8.  Financial  Statements  and
Supplementary Data, “Note 14 - Subsequent Events” in the accompanying Notes to Consolidated Financial Statements.

As of December 31, 2019, we had an accumulated deficit of $195.6 million. During the years ended December 31, 2019 and 2018, we incurred a net
loss of $38.4 million and $17.5 million,  respectively,  and  expect  to  incur  additional  losses  in  the  future.  We  have  not  achieved  positive  cash  flow  from
operations to date. As of December 31, 2019 and 2018, we had $39.2 million and $39.0 million, respectively, principal amount of outstanding debt, net of
debt  issuance  costs.  The  debt  covenants  associated  with  our  current  debt  agreement  require  us  to  maintain  a  minimum  cash  balance  and  meet  either
minimum net sales or trailing 12-month consolidated earnings before interest, taxes, depreciation, and amortization ("EBITDA") targets as discussed in
detail below. If we do not comply with these covenants, the debt will immediately become due.

Based upon our current operating plan, we believe that our existing cash, cash equivalents and short-term investments will enable us to fund our
operating expenses and capital expenditure requirements through at least the next 12 months. We continue to face challenges and uncertainties and, as a
result,  our  available  capital  resources  may  be  consumed  more  rapidly  than  currently  expected  due  to:  (a)  decreases  in  sales  of  our  products  and  the
uncertainty of future revenues from new products; (b) changes we may make to the business that affect ongoing operating expenses; (c) changes we may
make in our business strategy; (d) regulatory developments affecting our existing products; (e) changes we may make in our research and development
spending plans; and (f) other items affecting our forecasted level of expenditures and use of cash resources.

If we need to raise additional capital to fund our operations, funding may not be available to us on acceptable terms, or at all. If we are unable to
obtain adequate financing when needed, we may have to delay, reduce the scope of or suspend one or more of our sales and marketing efforts, research and
development  activities,  or  other  operations.  We  may  seek  to  raise  any  necessary  additional  capital  through  a  combination  of  public  or  private  equity
offerings,  debt  financings,  and  collaborations  or  licensing  arrangements.  If  we  do  raise  additional  capital  through  public  or  private  equity  offerings,  the
ownership interest of our existing stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely
affect our stockholders’ rights. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability to
take specific actions, such as incurring additional debt, making capital expenditures, or declaring dividends. If we are unable to raise capital, we will need
to delay, reduce, or terminate planned activities to reduce costs. Doing so will likely harm our ability to execute our business plans.

Borrowings

Our outstanding debt is related to a term loan we entered with Biopharma Credit Investments IV Sub LP, or Pharmakon, in October 2017 for total
loan proceeds of $40.0 million. The term loan includes an interest-only period for 35 months through September 2020 and is then repaid in equal principal
payments plus interest through December 2022. The term loan carries a fixed interest rate of 11.5% and a closing fee of 1.5% of the funded amount, or $0.6
million. The term loan includes a pre-payment fee of the remaining interest payable for the first 30 months of the agreement if it is prepaid within the first
30 months, a 2% prepayment penalty for months 31-48, and a 1% penalty for months 49-60. The term loan is collateralized by all of our assets, including
intellectual property. The term loan requires us to maintain a minimum cash balance of $5.0 million.

Beginning in the first quarter of 2019, we are required to meet either minimum net sales or trailing 12-month consolidated EBITDA targets. We need
to meet one or the other, but not both. If we do not meet either the minimum net sales or trailing 12-month consolidated EBITDA targets, the debt will
immediately become due. The remaining minimum net sales and trailing 12-month consolidated EBITDA targets are as follows:

Cash Used in Operating Activities

Net cash used in operating activities increased by $17.1 million for the year ended December 31, 2019 compared to the year ended  December  31,
2018. Net cash used in operating activities for the year ended December 31, 2019 of $31.6 million resulted from cash outflows due to a net loss of $38.4
million, adjusted for $7.3 million of non-cash items, and cash outflows from changes in operating assets and liabilities of $0.5 million. Net cash used in
operating activities for the year ended December 31, 2018 of $14.5 million resulted from cash outflows due to a net loss of $17.5 million, adjusted for $4.0
million of non-cash items, and cash outflows from changes in operating assets and liabilities of $1.0 million. The increase in net loss, net of non-cash items
for the year ended December 31, 2019 compared to the year ended December 31, 2018 was mainly due to higher operating expenses from expansion of the
business, partially offset by higher revenue. Cash outflows from changes in operating assets and liabilities for the years ended December 31, 2019 and 2018
were primarily due to increases in inventories and accounts receivable as a result of increased case volumes and growth of the business, partially offset by
increases in accounts payable, accrued expenses and other liabilities due to timing of payments and accrual of litigation expense.

Cash Provided by (Used in) Investing Activities

Net cash provided by investing activities in the year ended December 31, 2019 was $13.5 million compared to net cash used in investing activities of
$97.8 million in the year ended December 31, 2018. Cash provided by investing activities for the year ended December 31, 2019 consisted of maturities of
our  marketable  securities  of  $159.8  million,  partially  offset  by  purchases  of  marketable  securities  of  $143.9  million  and  purchases  of  property  and
equipment  of  $2.4 million.  Net  cash  used  in  investing  activities  for  the  year ended December  31,  2018  primarily  consisted  of  purchases  of  marketable
securities of $96.9 million, which was mainly from the net proceeds from our IPO, and purchases of property and equipment of $0.9 million.

Cash Provided by Financing Activities

Cash  provided  by  financing  activities  in  the  year  ended  December  31,  2019  was  $3.5  million  compared  to  $115.2  million  in  the  year  ended
December  31,  2018.  Cash  provided  by  financing  activities  for  the  year  ended  December  31,  2019  consisted  of  proceeds  received  from  stock  option
exercises of $1.5 million and proceeds received from issuance of shares of common stock under our employee stock purchase plan of $2.2 million, partially
offset by payments due to additional accrual of public offering costs of $0.2 million. Cash provided by financing activities for the year ended December 31,
2018 consisted of proceeds from our IPO, net of underwriting discounts and commissions of $115.5 million, and proceeds from exercise of stock options of
$1.6 million, partially offset by payments of public offering costs of $1.9 million and repurchases of common stock of $0.1 million.

Critical Accounting Policies, Significant Judgments, and Use of Estimates

This discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been
prepared  in  accordance  with  generally  accepted  accounting  principles  in  the  United  States  of  America  ("U.S.  GAAP").  The  preparation  of  these
consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure
of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported revenue generated, and expenses incurred
during  the  reporting  periods.  We  base  our  estimates  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.  We  believe  that  the  accounting  policies  discussed  below  are  critical  to  understanding  our
historical  and  future  performance,  as  these  policies  relate  to  the  more  significant  areas  involving  management’s  judgments  and  estimates.  For  more
comprehensive discussion of our significant accounting policies, refer to “Note 2 - Summary of Significant Account Policies” in the accompanying Notes
to Consolidated Financial Statements in Item 8 of this Form 10-K. We believe the following critical accounting policies reflect significant judgments and
estimates used in the preparation of our consolidated financial statements:

•

•

•

revenue recognition;

stock-based compensation; and

income taxes

Revenue Recognition

We derive our revenue from the sale of our products to medical groups and hospitals through our direct sales force and distributors throughout the
U.S.  and  Europe.  Through  the  year  ended  December  31,  2018,  in  accordance  with  ASC  Topic  605,  Revenue  Recognition  ("ASC  605"),  we  recognized
revenue when persuasive evidence of an arrangement exists, title and risk of loss has transferred to the customer, the sales price is fixed or determinable,
and collectability is reasonably assured.

As a result of the adoption of the new revenue standard in accordance with ASC Topic 606, Revenue from Contracts with Customers ("ASC 606")
effective for the fiscal year ended December 31, 2019, we now recognize revenue when control is transferred to the customer, in an amount that reflects the
consideration we expect to be entitled to in exchange for the goods or services. Under the new revenue recognition standard, we apply the following five
step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4)
allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when a performance obligation is satisfied. There
had been no material differences in our revenue recognition accounted for under ASC 605 and ASC 606. The adoption of the new revenue standard did not
result to a material impact on our consolidated financial statements. For more comprehensive discussion of our adoption to the new revenue standards, refer
to "Adoption of New Revenue Recognition Standard" in “Note 2 - Summary of Significant Account Policies” in the accompanying Notes to Consolidated
Financial  Statements  in  Item  8  of  this  Form  10-K.  As  it  relates  to  product  sales  where  our  sales  representative  delivers  the  product  at  the  point  of
implantation  at  hospital  or  other  medical  facilities,  we  continue  to  recognize  the  revenue  upon  completion  of  the  procedure  and  authorization  by  the
customer, net of rebates and price discounts. This represents majority of our consolidated revenue. We also generate a small portion of our revenue from
sale of products through distributors and hospital or medical facilities where the product is ordered in advance of a procedure. The performance obligation
is  the  delivery  of  the  product  and  therefore,  we  recognize  revenue  upon  shipment  to  the  customers,  net  of  rebates  and  price  discounts.  We  account  for
rebates and price discounts as reduction to revenue, calculated based on the terms agreed to with the customer. Historically, there had been no significant
price discounts. Sales prices are specified in either customer contract, agreed price list, or purchase order, which is executed prior to the transfer of control
to the customer. For certain hospitals and medical facilities, we have agreements in place consists of either a master services agreement or an approved
price  list,  which  defines  the  terms  and  conditions  of  the  arrangement,  including  the  pricing  information,  payment  terms  and  pertinent  aspects  of  the
relationship  between  the  parties.  We  also  have  agreements  in  place  with  its  distributors,  which  include  standard  terms  that  do  not  allow  for  payment
contingent on resale of the product, obtaining financing, or other terms that could impact the distributor’s payment obligation. Our standard payment terms
are generally net 30 to 90 days.

We consider sales commissions and related expenses as incremental and recoverable costs of acquiring customer contracts. Our sales commissions
paid to our sales representatives commensurate for each surgery performed. The period of benefit is concurrent when we recognize our revenue, as such,
we also recognize sales commission as expense when incurred.

Stock-Based Compensation

We  apply  the  fair  value  recognition  provisions  of  stock-based  compensation.  We  recognize  stock-based  compensation  expense  over  the  requisite
service period using the straight-line method and is based on the value of the portion of stock-based payment awards that is ultimately expected to vest. As
such, we reduce our stock-based compensation for the estimated forfeitures at the date of grant and revised, if necessary, in subsequent periods if actual
forfeitures  differ  from  those  estimates.  We  use  historical  data  to  estimate  pre-vesting  forfeitures  and  record  stock-based  compensation  expense  only  for
those awards that we expect to vest. To the extent actual forfeitures differ from the estimates, we record the difference as a cumulative adjustment in the
period that the estimates are revised.

We estimate the grant date fair value of stock options using the Black-Scholes option valuation model. The model requires us to make a number of
assumptions including expected volatility, expected term, risk-free interest rate and expected dividends. A number of these assumptions are subjective, and
their determination generally require judgment.

•

•

•

Expected Term - The expected term represents the period that we expect the share-based awards to be outstanding. We use the simplified method
to determine the expected term as permitted by the guidance since we have no sufficient historical exercise patterns to estimate the expected life.
The simplified method is calculated as the average of the time to vesting and the contractual life of the options.

Expected  Volatility  -  Since  we  became  public  in  October  2018  and  have  no  sufficient  trading  history,  we  use  stock  price  volatility  using  the
average  historical  volatilities  of  publicly  traded  companies  within  our  industry  that  we  consider  comparable  to  our  business  over  a  period
approximately equal to the expected term of our stock options.

Risk-Free Interest Rate - We base the risk-free interest rate on the U.S. Treasury zero coupon issued in effect at the time of grant for periods
corresponding with the expected term of the option.

67

•

Dividend Yield - We have not paid any dividends and we have no current plans to pay dividends on our common stock. As such, we use expected
dividend yield of zero.

We base the fair value of the restricted stock unit ("RSU") grant on the market price of our common stock on the date of grant.

Prior to IPO, the fair value of the shares of our common stock has historically been determined by our Board of Directors since there were no public
market information available for our common stock. The estimated fair value of our common stock was determined at each valuation date in accordance
with the guidelines outlined in the American Institute of Certified Public Accountants Practice Aid, Valuation of Privately-Held-Company Equity Securities
Issued  as  Compensation.  Our  Board  of  Directors,  with  the  assistance  of  management  and  independent  third-party  valuation  experts,  developed  these
valuations and took into account numerous factors, including developments at our company, market conditions, and contemporaneous independent third-
party valuations. In valuing our common stock, the fair value of our business, or enterprise value, was determined using both the income approach and
market approach. The income approach estimates value based on the expectation of future cash flows. The market approach estimates value based on a
comparison of the subject company to comparable public companies in a similar line of business. The assumptions used in determining the fair value of our
common  stock  involved  management's  best  estimates  and  judgments  at  the  time  the  valuation  was  performed.  Subsequent  to  our  IPO,  we  now  use  the
market closing price our common stock as reported on the Nasdaq Global Market on the date of grant.

We record equity instruments issued to non-employees at their fair value on the measurement date which are subject to periodic adjustments as the
underlying  equity  instruments  vest.  We  believe  that  the  estimated  fair  value  of  the  stock  options  is  more  readily  measurable  than  the  fair  value  of  the
services received. We recognize stock-based compensation related to stock options granted to non-employees as the stock options are earned.

In the event we modify the underlying terms of stock options on which stock-based compensation was granted, we recognize additional expense for

any modification that increases the total fair value of the share-based payment arrangement at the modification date.

Income Taxes

We account for income taxes under the liability method, whereby we determine deferred tax assets and liabilities based on the difference between the
financial  statement  and  tax  bases  of  assets  and  liabilities  using  the  enacted  tax  rates  in  effect  for  the  year  in  which  we  expect  the  differences  to  affect
taxable income.

We recognize uncertain tax positions when it meets a more-likely-than-not threshold. We recognize potential accrued interest and penalties related to
unrecognized  tax  benefits  as  income  tax  expense.  We  assess  all  material  positions  taken  in  any  income  tax  return,  including  all  significant  uncertain
positions, in all tax years that are still subject to assessment. Assessing an uncertain tax position begins with the initial determination of the sustainability of
the position and is measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. As of each
balance  sheet  date,  unresolved  uncertain  tax  positions  must  be  reassessed,  and  we  will  determine  whether  (i)  the  factors  underlying  the  sustainability
assertion  have  changed  and  (ii)  the  amount  of  the  recognized  tax  benefit  is  still  appropriate.  The  recognition  and  measurement  of  tax  benefits  requires
significant judgment. Judgments concerning the recognition and measurement of a tax benefit may change as new information becomes available.

We record a valuation allowance to reduce deferred tax assets when management cannot conclude that it is more-likely-than-not that the net deferred
tax asset will be recovered. The valuation allowance is determined by assessing both positive and negative evidence to determine whether it is more-likely-
than-not  that  deferred  tax  assets  are  recoverable;  such  assessment  is  required  on  a  jurisdiction-by-jurisdiction  basis.  There  is  judgment  required  in
determining whether we should record the valuation allowance against deferred tax assets. We continue to maintain a full valuation allowance against our
deferred tax assets due to the uncertainty surrounding realization of these assets. The realization of net deferred tax assets is dependent on our ability to
generate sufficient future taxable income during periods prior to the expiration of tax attributes to fully utilize these assets.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements that have, or are reasonably likely to have, a current or future effect on our financial condition, results of

operations, liquidity, capital expenditures or capital resources that is material to investors.

Seasonality

Our business is affected by seasonal variations. For instance, we have historically experienced lower sales in the summer months and higher sales in

the last quarter of the fiscal year. However, taken as a whole, seasonality does not have a material impact on our financial results.

68

JOBS Act Accounting Election

In April 2012, the JOBS Act was enacted. Section 107(b) of the JOBS Act provides that an “emerging growth company” can take advantage of the
extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. Thus, an emerging
growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected
to avail ourselves of this exemption and, therefore, are not be subject to the same new or revised accounting standards as other public companies that are
not emerging growth companies.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of SI-BONE, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of SI-BONE, Inc. and its subsidiaries (the “Company”) as of December 31, 2019 and
2018, and the related consolidated statements of operations and comprehensive loss, of changes in redeemable convertible preferred stock and stockholders'
equity  (deficit)  and  of  cash  flows  for  each  of  the  years  then  ended,  including  the  related  notes  (collectively  referred  to  as  the  “consolidated  financial
statements”).  In  our  opinion,  the  consolidated  financial  statements  present  fairly,  in  all  material  respects,  the  financial  position  of  the  Company  as  of
December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the years then ended in conformity with accounting principles
generally accepted in the United States of America.

Basis for Opinion

These  consolidated  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to  express  an  opinion  on  the
Company’s  consolidated  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 of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we
plan and perform the audits to obtain reasonable assurance about whether the consolidated 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 consolidated financial statements, whether due to error
or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and
disclosures in the consolidated 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 consolidated financial statements. We believe that our audits provide a reasonable basis
for our opinion.

1. The Company and Nature of Business

SI-BONE, Inc. (the “Company”) was incorporated in the state of Delaware on March 18, 2008 and is headquartered in Santa Clara, California. The
Company is a medical device company that has pioneered a proprietary minimally invasive surgical implant system to fuse the sacroiliac joint for treatment
of the most common types of sacroiliac joint disorders that cause lower back pain. The Company introduced its primary product, the iFuse Implant System,
or iFuse, in 2009 in the U.S., in 2010 in certain countries in the European Union, and in 2015 in certain countries in the rest of the world.

Reverse Stock Split

In October 2018, the Company's board of directors and stockholders approved a 1-for-18 reverse stock split of the Company's common stock and
redeemable convertible preferred stock, which was effected on October 4, 2018. The par value of the common stock and redeemable convertible preferred
stock was not adjusted as a result of the reverse split. All issued and outstanding share and per share amounts of common stock, redeemable convertible
preferred stock, stock options, and warrants included in the accompanying consolidated financial statements have been adjusted to reflect this reverse stock
split for all periods presented.

Initial Public Offering

On October 16, 2018, the Company’s Registration Statement on Form S-1 (File No. 333-227445) relating to the initial public offering ("IPO") of its
common stock was declared effective by the Securities and Exchange Commission ("SEC"). Pursuant to such Registration Statement, the Company sold
8,280,000 shares at an initial public offering price of $15.00 per share for net proceeds of $113.4 million to the Company, net of underwriting discounts and
commissions  and  offering  costs.  Upon  the  closing  of  the  IPO,  all  of  the  Company's  outstanding  shares  of  redeemable  convertible  preferred  stock  were
automatically converted into an aggregate of 12,066,654 shares of common stock and the Company's outstanding warrants to purchase 156,550 shares of
redeemable convertible preferred stock were automatically converted into warrants to purchase an aggregate of 160,657 shares of common stock, resulting
in reclassification of the related redeemable convertible preferred stock warrant liability of $1.2 million to additional paid-in-capital.

2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United
States  of  America  (“U.S.  GAAP”).  The  consolidated  financial  statements  include  the  Company's  accounts,  as  well  as  those  of  the  Company's  wholly-
owned international subsidiaries. All inter-company accounts and transactions have been eliminated.

Use of Estimates

The  preparation  of  financial  statements  in  conformity  with  U.S.  GAAP  requires  management  to  make  estimates  and  assumptions  that  affect  the
reported  amounts  of  assets  and  liabilities  and  disclosure  of  contingent  assets  and  liabilities  as  of  the  date  of  the  financial  statements  and  the  reported
amounts of revenue and expenses during the reporting period. Significant accounting estimates and management judgments reflected in the consolidated
financial statements include: fair value of assets and liabilities; analysis of the allowance for doubtful accounts; inventory valuation; valuation of deferred
tax  assets,  including  related  valuation  allowances;  fair  value  of  common  stock  and  redeemable  convertible  preferred  stock  warrants;  stock-based
compensation; and useful lives of long-lived assets. Estimates are based on historical experience, where applicable and other assumptions believed to be
reasonable by the management. Actual results could differ from those estimates.

JOBS Act Accounting Election

As  an  emerging  growth  company  under  the  Jumpstart  Our  Business  Startups  Act  of  2012  (the  "JOBS  Act"),  the  Company  is  eligible  to  take
advantage  of  certain  exemptions  from  various  reporting  requirements  that  are  applicable  to  other  public  companies  that  are  not  emerging  growth
companies.  The  Company  has  elected  to  take  advantage  of  the  extended  transition  period  for  adopting  new  or  revised  accounting  standards  that  have
different  effective  dates  for  public  and  private  companies.  Those  standards  apply  to  companies  until  the  earlier  of  the  date  that  it  is  (i)  no  longer  an
emerging  growth  company  or  (ii)  affirmatively  and  irrevocably  opt  out  of  the  extended  transition  period  provided  in  the  JOBS  Act.  As  a  result,  these
consolidated  financial  statements  may  not  be  comparable  to  companies  that  comply  with  the  new  or  revised  accounting  pronouncements  as  of  public
company effective dates. The Company continues to be an emerging growth company until December 31, 2023, unless one of the following occurs: (i) if
the Company's total annual gross revenues are $1.07 billion or more; or (ii) the Company has issued more than $1.0 billion in non-convertible debt in the
past three years; or (iii) the Company becomes a "large accelerated filer," as defined in Rule 12b-2 of the Exchange Act.

Segments

Operating segments are based on components of the Company that engage in business activities that earn revenue and incur expenses and (a) whose
operating  results  are  regularly  reviewed  by  the  Company’s  chief  operating  decision  maker  ("CODM"),  to  make  decisions  about  resource  allocation  and
performance and (b) for which discrete financial information is available. The CODM for the Company are the Chief Executive Officer ("CEO") and Chief
Operating Officer & Chief Financial Officer ("COO/CFO"). The CEO and the COO/CFO review financial information presented on a consolidated basis,
accompanied  by  information  about  revenue  by  geographic  region,  for  purposes  of  evaluating  financial  performance.  The  Company  has  one  business
activity  and  there  are  no  segment  managers  who  are  held  accountable  for  operations,  operating  results  or  plans  for  levels  or  components  below  the
consolidated unit level. Accordingly, the Company has determined that it has a single reportable and operating segment structure.

The Company derives substantially all of its revenue from sales to customers in the U.S. Revenue by geography is based on billing address of the
customer. No single country outside the U.S. accounts for more than 10% of the total revenue during the periods presented. Long-lived assets held outside
the U.S. are immaterial. Following table summarizes the Company's revenue by geography:

The Company’s foreign subsidiaries use local currency as their functional currency. Assets and liabilities are translated at exchange rates prevailing at
the balance sheet dates. Revenue, costs and expenses are translated into U.S. dollars using average exchange rates for the period. Gains and losses from
foreign  currency  translation  are  recorded  as  a  component  of  accumulated  other  comprehensive  income  (loss).  Gains  and  losses  from  foreign  currency
transactions are recognized as a component of other income (expense), net.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash and marketable securities. The Company’s
cash  and  marketable  securities  are  deposited  with  financial  institutions  in  the  U.S.  and  in  Europe.  The  majority  of  the  Company’s  cash  and  marketable
securities are deposited with a single financial institution in the U.S. Deposits in this institution exceed the amount of insurance provided on such deposits.
The Company has not experienced any net losses on its deposits of cash and marketable securities.

The Company’s revenue and accounts receivable are spread across a large number of customers, primarily in the U.S., and no customer accounts for

more than 10% of total revenue or gross accounts receivable in any period presented.

Other Risks and Uncertainties

The Company is subject to risks common to medical device companies including, but not limited to, new technological innovations, dependence on
key personnel, protection of proprietary technology, compliance with government regulations, product liability, the ability to obtain adequate coverage and
reimbursement from third-party payors and uncertainty of market acceptance of products.

The Company is dependent on third-party manufacturers and suppliers, in some cases single source suppliers. The Company currently has limited
long  term  contracts  with  its  key  suppliers  and  is  subject  to  risks  such  as  manufacturing  failures,  non-compliance  with  regulatory  requirements,  price
fluctuations, inability to properly meet demand and third-party supplier discontinuation of operations.

Liquidity

As of December 31, 2019, the Company had cash and marketable securities of $93.1 million compared to $122.2 million as of December 31, 2018.
Since inception, the Company financed its operations through its initial public offering, private placements of preferred stock, debt financing arrangements,
and the sale of products. As of December 31, 2019, the Company's accumulated deficit was $195.6 million. During the years ended December 31, 2019 and
2018, the Company incurred a net loss of $38.4 million and $17.5 million, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company also has certain debt covenants associated with its current debt agreement. These covenants include a $5.0 million  minimum  cash
balance and revenue targets, which if not met would result in the debt becoming immediately due. The Company is required to meet either minimum net
sales  or  trailing  12-month  consolidated  earnings  before  interest,  taxes,  depreciation,  and  amortization  ("EBITDA")  targets.  The  Company  was  in
compliance with all debt covenants as of December 31, 2019 and 2018.

Based upon the Company's current operating plan, the Company believes that its existing cash and marketable securities will enable the Company to
fund  its  operating  expenses  and  capital  expenditure  requirements  through  at  least  the  next  12  months.  The  Company  continues  to  face  challenges  and
uncertainties and, as a result, its available capital resources may be consumed more rapidly than currently expected due to: (a) decreases in sales of our
products and the uncertainty of future revenues from new products; (b) changes that the Company may make to the business that affect ongoing operating
expenses;  (c)  changes  that  the  Company  may  make  in  its  business  strategy;  (d)  regulatory  developments  affecting  the  Company's  existing  products;
(e) changes that the Company may make in its research and development spending plans; and (f) other items affecting the Company's forecasted level of
expenditures and use of cash resources.

Fair Value of Financial Instruments

Carrying amounts of certain of the Company’s financial instruments, including cash equivalents, accounts receivable, accounts payable, and accrued
liabilities, approximate fair value due to their relatively short maturities and market interest rates, if applicable. The Company's marketable securities are
classified as Level 1 or Level 2 of the fair value hierarchy as defined below. The carrying value of the Company’s long-term debt also approximates fair
value based on management’s estimation that a current interest rate would not differ materially from the stated rate.

The Company discloses and recognizes the fair value of its assets and liabilities using a hierarchy that prioritizes the inputs to valuation techniques
used to measure fair value. 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 liability. As a basis for considering such assumptions, a three-tier value hierarchy has been established,
which prioritizes the inputs used in measuring fair value as follows:

Level 1: Quoted prices (unadjusted) in active market that are accessible at measurement date for assets or liabilities. The fair value hierarchy gives

the highest priority to Level 1 inputs.

Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.

Level 3: Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.

Assets  and  liabilities  measured  at  fair  value  are  classified  in  their  entirety  based  on  the  lowest  level  of  input  that  is  significant  to  the  fair  value
measurement.  The  Company’s  assessment  of  the  significance  of  a  particular  input  to  the  fair  value  measurement  in  its  entirety  requires  management  to
make judgments and considers factors specific to the asset or liability.

Cash and Cash Equivalents

The Company considers all highly liquid investments with remaining maturities at the date of purchase of three months or less to be cash equivalents.

Marketable Securities

The  Company's  marketable  securities  primarily  consist  of  investments  in  money  market  funds,  U.S.  treasury  securities,  corporate  bonds  and
commercial paper. All of the Company's marketable securities are available-for-sale and are classified based on their maturities. Marketable securities with
remaining maturities at the date of purchase of three months or less are classified as cash equivalents. Short term investments are securities that original or
remaining maturity is greater than three months and not more than twelve months. Long-term investments are securities that original or remaining maturity
is more than twelve months. All marketable securities are recorded at their estimated fair value. Unrealized gains and losses on available-for-sale securities
are  recorded  in  accumulated  other  comprehensive  income  (loss)  ("OCI")  on  the  consolidated  balance  sheets.  The  Company  evaluates  its  investments  to
assess whether those in unrealized loss positions are other-than-temporarily impaired. The Company considers impairments to be other-than-temporary if
they are related to deterioration in credit risk or if it is likely the Company will sell the securities before the recovery of their cost basis. Realized gains and
losses and declines in value judged to be other-than-temporary are determined based on the specific identification method and are reported in other income
(expense), net on the consolidated statements of operations.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts  receivable  are  recorded  at  the  invoiced  amount  and  do  not  bear  interest.  The  Company  generally  does  not  require  collateral  or  other
security in support of accounts receivable. Allowances are provided for individual accounts receivable when the Company becomes aware of a customer’s
inability to meet its financial obligations, such as in the case of bankruptcy, deterioration in the customer’s operating results or change in financial position.
If circumstances related to customers change, estimates of the recoverability of receivables would be further adjusted. The Company also considers broad
factors  in  evaluating  the  sufficiency  of  its  allowance  for  doubtful  accounts,  including  the  length  of  time  receivables  are  past  due,  significant  one-time
events, creditworthiness of customers and historical experience. Account balances are charged off against the allowance after all means of collection have
been exhausted and the potential for recovery is considered remote.

Inventory

Inventory is stated at lower of cost or net realizable value. The Company establishes the inventory basis by determining the cost based on standard
costs approximating the purchase costs on a first-in, first-out basis. The excess and obsolete inventory is estimated based on future demand and market
conditions. Inventory write-downs are charged to cost of goods sold.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation and amortization. All property and equipment is depreciated on a straight-

line basis over the estimated useful lives of the assets, which are as follows:

Computer and office equipment

Machinery and equipment

Furniture and fixtures

3 – 5 years

3 – 5 years

7 years

Leasehold improvements are amortized over the lesser of their useful lives or the life of the lease. Upon sale or retirement of the assets, the cost and
related accumulated depreciation are removed from the consolidated balance sheet and the resulting gain or loss is recognized in the consolidated statement
of operations. Maintenance and repairs are charged to operations as incurred.

Impairment of Long-Lived Assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets
(or asset group) may not be fully recoverable. Whenever events or changes in circumstances suggest that the carrying amount of long-lived assets may not
be recoverable, the Company estimates the future cash flows expected to be generated by the assets (or asset group) from its use or eventual disposition. If
the sum of the expected future cash flows is less than the carrying amount of those assets, the Company recognizes an impairment loss based on the excess
of the carrying amount over the fair value of the assets. Significant management judgment is required in the grouping of long-lived assets and forecasts of
future  operating  results  that  are  used  in  the  discounted  cash  flow  method  of  valuation.  Through  December  31,  2019  and  2018,  the  Company  has  not
experienced impairment losses on its long-lived assets.

Revenue Recognition

The  Company’s  revenue  is  derived  from  the  sale  of  its  products  to  medical  groups  and  hospitals  through  its  direct  sales  force  and  distributors
throughout the U.S. and Europe. Through the year ended December 31, 2018, in accordance with ASC Topic 605, Revenue Recognition ("ASC 605"), the
Company recognized revenue when persuasive evidence of an arrangement exists, title and risk of loss has transferred to the customer, the sales price is
fixed or determinable, and collectability is reasonably assured.

As a result of the adoption of the new revenue standard in accordance with ASC Topic 606, Revenue from Contracts with Customers ("ASC 606")
effective for the fiscal year ended December 31, 2019, the Company now recognizes the revenue when control is transferred to the customer, in an amount
that reflects the consideration the Company expects to be entitled to in exchange for the goods or services. Under the new revenue recognition standard, the
Company applies the following five step approach: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3)
determine  the  transaction  price,  (4)  allocate  the  transaction  price  to  the  performance  obligations  in  the  contract,  and  (5)  recognize  revenue  when  a
performance obligation is satisfied. There had been no material differences in the Company’s revenue recognition accounted for under ASC 605 and ASC
606.  As  it  relates  to  product  sales  where  the  Company's  sales  representative  delivers  the  product  at  the  point  of  implantation  at  the  hospital  or  medical
facilities, the Company continues to recognize the revenue upon completion of the procedure and authorization by the customer, net of rebates and price
discounts. This represents the majority of the Company's consolidated revenue. The Company also generates a small portion of revenue from the sale of
products  through  distributors  and  to  certain  hospital  or  medical  facilities  where  the  products  are  ordered  in  advance  of  a  procedure.  The  performance
obligation  is  the  delivery  of  the  products  and  therefore,  revenue  is  recognized  upon  shipment  to  the  customers,  net  of  rebates  and  price  discounts.  The
Company accounts for rebates and price discounts as reduction to revenue, calculated based on the terms agreed to with the customer. Historically, there
had been no significant price discounts. Sales prices are specified in either the customer contract, agreed price list, or purchase order, which is executed
prior to the transfer of control to the customer. For certain hospitals and medical facilities, the Company has agreements in place consists of either a master
services agreement or an approved price list, which defines the terms and conditions of the arrangement, including the pricing information, payment terms
and pertinent aspects of the relationship between the parties. The Company also has agreements in place with its distributors, which include standard terms
that  do  not  allow  for  payment  contingent  on  resale  of  the  product,  obtaining  financing,  or  other  terms  that  could  impact  the  distributor’s  payment
obligation. The Company's standard payment terms are generally net 30 to 90 days.

Shipping and Handling Costs

Shipping and handling costs are treated as fulfillment costs, which are expensed as incurred and are included in cost of goods sold.

Costs to Obtain Customer Contracts

Sales  commissions  and  related  expenses  are  considered  incremental  and  recoverable  costs  of  acquiring  customer  contracts.  The  Company’s  sales
commissions paid to its sales representatives is generally based on the surgeries performed. The Company applied the practical expedient that permits an
entity to expense the cost to obtain a contract as incurred when the expected amortization is one year or less. The period of benefit is concurrent with when
the Company recognizes its revenue and as such, the Company recognizes sales commission as expense when incurred.

Warranty

The Company has a warranty program that provides a purchaser a one-time replacement of any iFuse implant at no additional cost for a revision
procedure within a one-year period following the original procedure and is accounted for as a warranty accrual. The Company also provides a purchaser
with  a  one-time  credit  equal  to  the  purchase  price  paid  for  use  on  future  purchases  for  any  revision  procedure  within  the  one-year period following an
original procedure where an implant is not required. The warranty is not priced or sold separately and is intended to safeguard the customer against defects
and it does not provide incremental service to the customer. As such, it is considered an assurance type warranty and is not accounted as a service type
warranty, which could represent a separate performance obligation. The Company accounts for these one-time credits as sales reserves and is included in
accrued liabilities and other in the consolidated balance sheets. Sales and warranty reserves from the warranty program were immaterial as of December 31,
2019 and 2018.

Medical Device Excise Tax

In accordance with the Patient Protection and Affordable Care Act, effective January 1, 2013, the Company began to incur an excise tax on sales of
medical devices in the U.S. The Company recorded the medical device excise tax within the cost of goods sold in the consolidated statements of operations
and comprehensive loss when incurred. Effective January 1, 2016, the Consolidated Appropriations Act of 2016, which was signed into law in December
2015, included a two-year suspension on the medical device excise tax. In January 2018, the suspension on the tax on medical devices was further extended
through January 1, 2020. In December 2019, the U.S. Senate passed a bipartisan legislation to permanently repeal the medical device excise tax.

Research and Development

Research  and  development  costs  are  charged  to  operations  as  incurred  and  consist  of  costs  incurred  by  the  Company  for  the  development  of  the
Company’s  product  which  primarily  include  (1)  employee-related  expenses,  including  salaries,  benefits,  travel  and  non-cash  stock-based  compensation
expense (2) external research and development expenses (3) other expenses, which include direct and allocated expenses for facilities and other costs.

Advertising Expenditures

The  cost  of  advertising  is  expensed  as  incurred  and  is  included  under  sales  and  marketing  expense  in  the  consolidated  statements  of  operations.

Advertising expenses were $0.4 million and $0.7 million for the year ended December 31, 2019 and 2018, respectively.

Loss Contingency

The Company is subject to various potential loss contingencies arising in the ordinary course of business. From time to time, the Company may be
involved in certain proceedings, legal actions, and claims. Such matters are subject to many uncertainties, and the outcomes of these matters are not within
the Company's control and may not be known for prolonged periods of time. In some actions, the claimants may seek damages, as well as other relief,
including injunctions which may prohibit the Company to engage in certain activities, which, if granted, could require significant expenditures and/or result
in lost revenues. The Company records a liability in the consolidated financial statements when a loss is known or considered probable and the amount can
be reasonably estimated. If the reasonable estimate of a known or probable loss is a range, and no amount within the range is a better estimate than any
other,  the  minimum  amount  of  the  range  is  accrued.  If  a  loss  is  reasonably  possible  but  not  known  or  probable,  and  can  be  reasonably  estimated,  the
estimated loss or range of loss is disclosed. In most cases, significant judgment is required to estimate the amount and timing of a loss to be recorded.

Stock-Based Compensation

The Company applies the fair value recognition provisions of stock-based compensation. Stock-based compensation expense is recognized over the
requisite service period using the straight-line method and is based on the value of the portion of stock-based payment awards that is ultimately expected to
vest. As such, the Company’s stock-based compensation is reduced for the estimated forfeitures at the date of grant and revised, if necessary, in subsequent
periods  if  actual  forfeitures  differ  from  those  estimates.  The  Company  uses  historical  data  to  estimate  pre-vesting  forfeitures  and  record  stock-based
compensation  expense  only  for  those  awards  that  are  expected  to  vest.  To  the  extent  actual  forfeitures  differ  from  the  estimates,  the  difference  will  be
recorded as a cumulative adjustment in the period that the estimates are revised.

The Company estimates the grant date fair value of stock options using the Black-Scholes option valuation model. The model requires management to
make a number of assumptions including expected volatility, expected term, risk-free interest rate and expected dividends. A number of these assumptions
are subjective, and their determination generally require judgment.

•

•

•

•

Expected  Term  -  The  expected  term  represents  the  period  that  the  share-based  awards  are  expected  to  be  outstanding.  The  Company  uses  the
simplified method to determine the expected term as permitted by the guidance since the Company has no sufficient historical exercise patterns to
estimate the expected life. The simplified method is calculated as the average of the time to vesting and the contractual life of the options.

Expected Volatility - Since the Company became public in October 2018 and has no sufficient trading history, the Company uses stock price volatility
using the average historical volatilities of publicly traded companies within its industry that the Company considers to be comparable to its business
over a period approximately equal to the expected term for its stock options.

Risk-Free  Interest  Rate  -  The  risk-free  interest  rate  is  based  on  the  U.S.  Treasury  zero  coupon  issued  in  effect  at  the  time  of  grant  for  periods
corresponding with the expected term of the option.

Dividend Yield - The Company has not paid any dividends and has no current plans to pay dividends on its common stock. As such, the Company
uses expected dividend yield of zero.

The fair value of the restricted stock unit ("RSU") grant is based on the market price of the Company’s common stock on the date of grant.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Prior to IPO, the fair value of the shares of the Company's common stock has historically been determined by its Board of Directors since there were
no public market information available for the Company's common stock. The estimated fair value of the Company's common stock was determined at
each  valuation  date  in  accordance  with  the  guidelines  outlined  in  the  American  Institute  of  Certified  Public  Accountants  Practice  Aid,  Valuation  of
Privately-Held-Company  Equity  Securities  Issued  as  Compensation.  The  Company's  Board  of  Directors,  with  the  assistance  of  management  and
independent third-party valuations, developed these valuations and took into account numerous factors, including developments of the Company, market
conditions, and contemporaneous independent third-party valuations. In valuing the Company's common stock, the fair value of its business, or enterprise
value, was determined using both the income approach and market approach. The income approach estimates value based on the expectation of future cash
flows. The market approach estimates value based on a comparison of the subject company to comparable public companies in a similar line of business.
The assumptions used in determining the fair value of the Company's common stock involved management's best estimates and judgments at the time the
valuation was performed. Subsequent to its IPO, the Company uses the market closing price for its common stock as reported on the Nasdaq Global Market
on the date of grant.

Equity instruments issued to non-employees are recorded at their fair value on the measurement date and are subject to periodic adjustments as the
underlying equity instruments vest. The Company believes that the estimated fair value of the stock options is more readily measurable than the fair value
of the services received. Stock-based compensation related to stock options granted to non-employees is recognized as the stock options are earned.

In the event the underlying terms of stock options are modified on which stock-based compensation was granted, additional expense is recognized for

any modification that increases the total fair value of the share-based payment arrangement at the modification date.

Income Taxes

The Company accounts for income taxes under the asset and liability method, whereby deferred tax assets and liabilities are determined based on the
difference between the financial statement and tax bases of assets and liabilities using the enacted tax rates in effect for the year in which the differences are
expected  to  affect  taxable  income.  A  valuation  allowance  is  established  when  necessary  to  reduce  deferred  tax  assets  to  the  amounts  expected  to  be
realized.

The Company recognizes uncertain tax positions when it meets a more-likely-than-not threshold. The Company recognizes potential accrued interest

and penalties related to unrecognized tax benefits as income tax expense. 

Net Loss per Share of Common Stock

The Company calculates basic and diluted net loss per common share attributable to shareholders in conformity with the two-class method required
for companies with participating securities. The Company considers all series of redeemable convertible preferred stock and early exercised stock options
to be participating securities as the holders are entitled to receive dividends on a pari passu basis in the event that a dividend is paid on common stock.
Under the two-class method, the net loss attributable to common stock is not allocated to the redeemable convertible preferred stock and early exercised
stock options as the holders of redeemable convertible preferred stock and early exercised stock options do not have a contractual obligation to share in
losses.

Basic net loss per common share is calculated by dividing the net loss by the weighted-average number of common shares outstanding during the
period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss by the weighted-average
number  of  common  shares  and  potentially  dilutive  securities  outstanding  for  the  period.  For  purposes  of  the  diluted  net  loss  per  share  calculation,
redeemable convertible preferred stock and common stock options and warrants are considered to be potentially dilutive securities. Because the Company
has  reported  a  net  loss  in  all  periods  presented,  redeemable  convertible  preferred  stock  and  common  stock  options  and  warrants  are  anti-dilutive  and
therefore diluted net loss per common share is the same as basic net loss per common share for those periods.

Comprehensive Loss

Comprehensive  loss  represents  all  changes  in  the  stockholders’  equity  (deficit)  except  those  resulting  from  distributions  to  stockholders.  The
Company’s unrealized foreign currency translation income (losses) and unrealized gains (losses) on marketable securities represent the two components of
other  comprehensive  income  that  are  excluded  from  the  reported  net  loss  for  each  of  the  reporting  periods  and  has  been  presented  in  the  consolidated
statements of operations and comprehensive loss.

Public Offering Costs

Specific  incremental  costs  (i.e.  consisting  of  legal,  accounting  and  other  fees  and  costs)  directly  attributable  to  a  proposed  or  actual  offering  of
securities may properly be deferred and charged against the gross proceeds of the offering. In the event a planned offering of securities does not occur or is
significantly delayed, all of the costs will be expensed. Upon completion of the IPO on October 16, 2018, the previously deferred and capitalized public
offering costs incurred which were recorded within prepaid expenses and other current assets were charged against the gross proceeds of the offering. No
public offering cost was deferred as of December 31, 2018.

On November 13, 2019, the Company filed a Shelf Registration Statement on Form S-3 with the SEC that was declared effective by the SEC on
November 25, 2019, registering a proposed maximum aggregate primary offering of $200.0 million of  unspecified number of shares of common stock;
shares of preferred stock; debt securities; or warrants to purchase shares of common stock that the Company may offer in one or more offerings on terms to
be determined at the time of sale (the "Prior Registration Statement"). On December 27, 2019, the Company filed a Shelf Registration Statement on Form
S-3 with the SEC that was declared effective by the SEC on January 2, 2020, registering the unsold maximum aggregate primary offering under the Prior
Registration  Statement  and  additional  2,000,000  shares  of  the  Company's  common  stock  held  by  the  selling  stockholders  to  be  named  in  a  prospectus
supplement, that may, from time to time, offer or sell in a secondary offering. The incremental costs incurred directly attributable to the shelf filing of $0.1
million were deferred within prepaid expenses and other current assets as of December 31, 2019. See “Note 14 - Subsequent Events” in the accompanying
Notes to Consolidated Financial Statements for discussions regarding the subsequent public offering.

Warrants

The  Company  accounts  for  warrants  for  shares  of  common  stock  as  equity  in  accordance  with  the  accounting  guidance  for  derivatives.  The
accounting guidance provides a scope exception from classifying and measuring as a financial liability a contract that would otherwise meet the definition
of a derivative if the contract is both (i) indexed to the entity’s own stock and (ii) classified in the stockholders’ deficit section of the consolidated balance
sheet.  The  Company  determined  that  the  warrants  for  shares  of  common  stock  issued  in  connection  with  its  prior  debt  arrangements  are  required  to  be
classified in equity. Warrants classified as equity are recorded as additional paid-in capital on the consolidated balance sheet and no further adjustments to
their valuation are made.

In connection with the IPO, all of the Company's redeemable convertible preferred stock warrants were automatically converted into common stock
warrants. The redeemable convertible preferred stock warrants were classified as liabilities on the consolidated balance sheet at their estimated fair value
because the shares underlying the warrants required the Company to transfer assets to the holders at a future date. The redeemable convertible preferred
stock warrants were measured at fair value and were subjected to re-measurement at each balance sheet date. The change in fair value were recognized in
other income (expense), net on the consolidated statements of operations. The Company estimated the fair value of these liabilities using option pricing
models and assumptions that were based on the individual characteristics of the warrants on the valuation date, as well as assumptions for future financings,
expected volatility, expected life, yield, and risk-free interest rate.

Adoption of New Revenue Recognition Standard

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts
with  Customers,  which  requires  an  entity  to  recognize  the  amount  of  revenue  to  which  it  expects  to  be  entitled  for  the  transfer  of  promised  goods  or
services  to  customers.  The  new  standard  is  effective  for  fiscal  years  beginning  after  December  15,  2017  for  public  companies,  and  for  fiscal  years
beginning after December 15, 2018, and interim periods beginning after December 15, 2019, for private companies. Early application is permitted. The
standard permits the use of either the retrospective or cumulative effect transition method. In March 2016, the FASB issued ASU 2016-08, which clarifies
the implementation guidance on principal versus agent considerations. In April 2016, the FASB issued ASU 2016-10, which clarifies certain aspects of
identifying performance obligations and licensing implementation guidance. In May 2016, the FASB issued ASU 2016-12, which relates to disclosures of
remaining performance obligations, as well as other amendments to guidance on collectability, non-cash consideration and the presentation of sales and
other similar taxes collected from customers. In November 2018, the FASB issued ASU 2018-18, which clarifies when transactions between participants in
a collaborative arrangement are within the scope of the FASB’s new revenue standard. 

83

SI-BONE, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The  Company  adopted  this  standard  using  the  modified  retrospective  method  effective  for  the  year  ended  December  31,  2019.This  approach  was
applied to all contracts that were not completed as of January 1, 2019. As an emerging growth company that elected to take advantage of the JOBS Act
accounting election, the Company was not required to adopt the new revenue standard in the interim reporting periods on the year of adoption and is not
required, and intends not, to revise its 2019 interim periods which were reported under ASC 605. The adoption of the new revenue standard did not result
to a material impact on the Company’s consolidated financial statements and no adjustment was made to the opening balance of accumulated deficit at
January  1,  2019. The  comparative  2018  period  has  not  been  adjusted  and  continued  to  be  reported  under  ASC  605.  ASC  606's  core  principle  is  that  a
reporting entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the
entity expects to be entitled in exchange for those goods or services. As it relates to product sales where the Company's sales representative delivers the
product  at  the  point  of  implantation  at  hospital  or  medical  facilities,  which  represents  majority  of  the  Company's  revenue,  the  Company  continues  to
recognize  the  revenue  upon  completion  of  the  procedure  and  authorization  by  the  customer,  net  of  rebates  and  price  discounts.  As  it  relates  to  sale  of
products  through  distributors  and  hospitals  where  product  is  ordered  in  advance  of  the  procedure,  the  Company  expects  to  continue  to  recognize  the
revenue upon shipments to the customers, net of rebates and price discounts. Additionally, the new standard requires the capitalization of costs to obtain a
contract,  primarily  sales  commissions,  and  amortization  of  these  costs  over  the  contract  period  or  estimated  customer  life.  The  Company’s  sales
commissions paid to its sales representatives is generally based on the surgeries performed. The Company applied the practical expedient that permits an
entity  to  expense  the  cost  to  obtain  a  contract  as  incurred  when  the  expected  amortization  is  one  year  or  less.  As  such,  the  Company  recognize  sales
commission as expense when incurred.

The Company disaggregates revenues from contracts with customers into geographical regions. The Company determined that disaggregating
revenue into these categories depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by regional economic factors.
For information revenue by geography, refer to Segments in “Note 2 - Summary of Significant Accounting Policies" in the accompanying Notes to
Consolidated Financial Statements.

Other Recently Adopted Accounting Standards

In July 2019, the FASB issued ASU 2019-07, Codification Updates to SEC Sections - Amendments to SEC Paragraphs Pursuant to SEC Final Rule
Releases  No.  33-10532,  Disclosure  Update  and  Simplification,  and  Nos.  33-10231  and  33-10442,  Investment  Company  Reporting  Modernization,  and
Miscellaneous Updates. This update clarifies or improves the disclosure and presentation requirements of a variety of codification topics by aligning them
with  the  SEC’s  regulations,  thereby  eliminating  redundancies  and  making  the  codification  easier  to  apply.  This  update  is  effective  upon  issuance.  The
Company does not expect the disclosure and presentation amendments included in this update, which are to be applied prospectively, to have a material
impact on its consolidated financial statements and related disclosures.

In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220). This update provides companies
with the option to reclassify stranded tax effects caused by the 2017 Tax Cuts and Jobs Act from accumulated other comprehensive income to retained
earnings. This standard is effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early
adoption  is  permitted.  The  Company  has  adopted  this  standard  effective  January  1,  2019,  and  the  adoption  did  not  have  any  material  impact  on  the
Company’s consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230), which provides guidance on the following eight specific cash
flow classification issues: (1) debt prepayment or debt extinguishment costs; (2) settlement of zero-coupon debt instruments or other debt instruments with
coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing; (3) contingent consideration payments made after a
business combination; (4) proceeds from the settlement of insurance claims; (5) proceeds from the settlement of corporate-owned life insurance policies,
including bank-owned life insurance policies; (6) distributions received from equity method investees; (7) beneficial interests in securitization transactions;
and  (8)  separately  identifiable  cash  flows  and  application  of  the  predominance  principle.  This  update  is  effective  for  reporting  periods  beginning  after
December  15,  2017  for  public  companies,  and  fiscal  years  beginning  after  December  15,  2018  and  interim  periods  within  fiscal  years  beginning  after
December  15,  2019  for  private  companies,  with  early  adoption  permitted.  The  Company  has  adopted  this  standard  effective  January  1,  2019,  and  the
adoption did not have any material impact on the Company’s consolidated financial statements.

Recently Issued Accounting Standards Not Yet Effective

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires that lessee's recognize a right-of-use asset and a lease liability
for all leases with lease terms greater than twelve months in the balance sheet. A lease liability is a lessee's obligation to make lease payments arising from
a lease, measured on a discounted basis; and a right-of-use asset is an asset that represents the lessee’s right to use, or control use of, a specified asset for
the lease term for all leases (with the exception of short-term leases) at the adoption date.  In July 2018, the FASB issued ASU 2018-10 and ASU 2018-11,
which provides clarification on the narrow aspects of the guidance and provide an additional transition method to adopt the new leases standard. The new
transition method allows an entity to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. In
March 2019, the FASB issued ASU 2019-01, which provides clarification on implementation issues associated with adopting ASU 2016-02. The new leases
standard  must  be  adopted  using  a  modified  retrospective  transition  method  and  allows  for  the  application  of  the  new  guidance  at  the  beginning  of  the
earliest comparative period presented or at the adoption date. In November 2019, the FASB issued ASU 2019-10, which revised the mandatory effective
dates of the new lease standard. For public companies, the new guidance remained effective for fiscal years, and for interim periods within those fiscal
years, beginning after December 15, 2018. For all other entities, the new guidance is now effective for fiscal years beginning after December 15, 2020 and
interim periods within fiscal years beginning after December 15, 2021. Early adoption is still permitted for any interim or annual financial statements not
yet issued.

As an emerging growth company, the new lease standard is now effective for the Company for the fiscal year ending December 31, 2021 and interim
periods  within  fiscal  year  ending  December  31,  2022.  The  Company  is  currently  evaluating  the  impact  of  this  standard  on  its  consolidated  financial
statements including the timing of its adoption. The Company anticipates electing several practical expedients that permit the Company not to reassess (1)
whether a contract is or contains a lease, (2) the classification of existing leases, and (3) whether previously capitalized initial direct costs would qualify for
capitalization under ASC 842. The Company expects that the adoption of this new standard will have a material impact on its balance sheet. The most
significant impact would be the recognition of operating lease right-of-use assets and liability. The standard is not expected to have a material impact to the
Company's consolidated statements of income and cash flows.

In  June  2016,  the  FASB  issued  ASU  2016-13,  Financial  Instruments-Credit  Losses  (Topic  326):  Measurement  of  Credit  Losses  on  Financial
Instruments. FASB issued ASU 2019-05 in May 2019 and ASU 2019-08 in November 2019 for codification improvements of Topic 326. The new standard
revises  the  accounting  requirements  related  to  the  measurement  of  credit  losses  and  will  require  organizations  to  measure  all  expected  credit  losses  for
financial assets based on historical experience, current conditions and reasonable and supportable forecasts about collectability. Assets must be presented in
the financial statements at the net amount expected to be collected. In November 2019, the FASB issued ASU 2019-10, which defers the effective date
of ASU 2016-13 for public companies that are eligible to be smaller reporting companies and all other companies, to fiscal years beginning after December
15,  2022,  including  interim  periods  within  those  fiscal  years.  In  February  2020,  the  FASB  issued  ASU  2020-02,  which  provides  guidance  regarding
methodologies, documentation, and internal controls related to expected credit losses. The Company is currently evaluating the impact of this standard on
its consolidated financial statements, but do not expect the standard will have a material impact on our consolidated financial statements.

In June 2018, the FASB issued ASU 2018-07, Improvements to Non-employee Share-Based Payment Accounting. ASU 2018-07 expands the scope
of  Topic  718,  Compensation-Stock  Compensation,  to  include  share-based  payments  issued  to  non-employees  for  goods  or  services.  Consequently,  the
accounting for share-based payments to non-employees and employees will be substantially aligned. ASU 2018-07 supersedes Subtopic 505-50, Equity-
Equity-Based Payments to Non-Employees. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2018,
including interim periods within that fiscal year. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2019, and
interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted, but no earlier than a company’s adoption date of ASC
606. The Company is currently evaluating the impact that the adoption of this standard will have on the consolidated financial statements and anticipates
adopting the standard for the fiscal year ending December 31, 2020.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurements, which eliminates, adds or modifies certain disclosure requirements for fair
value measurements. Entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value
hierarchy,  but  will  be  required  to  disclose  the  range  and  weighted  average  used  to  develop  significant  unobservable  inputs  for  Level  3  fair  value
measurements.  This  update  is  effective  for  fiscal  years  beginning  after  December  15,  2019,  including  interim  periods  within  that  fiscal  year,  with  early
adoption  permitted  to  adopt  either  the  entire  standard  or  only  the  provisions  that  eliminate  or  modify  the  requirements.  The  Company  is  currently
evaluating  the  impact  that  the  adoption  of  this  standard  will  have  on  the  consolidated  financial  statements  and  anticipates  adopting  the  standard  for  the
fiscal year ending December 31, 2020.

4. Fair Value Measurement

Carrying amounts of certain of the Company’s financial instruments, including cash equivalents, accounts receivable, accounts payable and accrued
liabilities, approximate fair value due to their relatively short maturities and market interest rates, if applicable. The carrying value of the Company’s long-
term debt also approximates fair value based on management’s estimation that a current interest rate would not differ materially from the stated rate. There
were no other financial assets and liabilities that requires fair value hierarchy measurements and disclosures for the periods presented.

Legal Proceedings

On February 6, 2019, a putative class action captioned Eric B. Fromer Chiropractic, Inc. ("Plaintiff") v. SI-BONE, Inc. (Civil Action No. 5:19-cv-
633-SVK), was filed in the U.S. District Court, Northern District of California. The complaint alleges violations of the Telephone Consumer Protection Act
(the  “TCPA”)  on  behalf  of  an  individual  and  a  putative  class  of  persons  alleged  to  be  similarly  situated.  The  complaint  alleges  that  the  Company  sent
invitations  to  an  educational  dinner  event  to  health  care  providers  by  way  of  facsimile  transmission.  The  TCPA  prohibits  using  a  fax  machine  to  send
unsolicited advertisements not including proper opt-out instructions or to send unsolicited advertisements to persons with whom the sender did not have an
established business relationship. The plaintiff sought various forms of relief, including statutory damages of $500 for each violation of the TCPA or, in the
alternative, treble damages of up to $1,500 for each knowing and willful violation of the TCPA and a permanent injunction prohibiting the Company from
sending or having sent advertisements by way of facsimile transmission. On December 23, 2019 the parties filed a joint stipulation of dismissal of the case
in the District Court in the Northern District of California and on January 14, 2020, the parties executed a definitive settlement agreement (the "Settlement
Agreement"), pursuant to which, the Company agreed to settle all disputes regarding the advertising faxes to the settlement class.

As  this  lawsuit  is  being  resolved  through  a  negotiated  settlement  and  class  resolution  process,  the  Company  believes  that  it  will  incur  a  loss
associated with resolution of the claims against it. The Company has accrued litigation expense of $3.2 million during the year ended December 31, 2019
within general and administrative expenses in the consolidated financial statements. The accrual reflects the estimable and probable costs that the Company
may incur based on estimated claims submitted by members of the settlement class, as defined in the Settlement Agreement. The final disposition of the
lawsuit may result in a loss in excess of the aggregate recorded amount.

Indemnification

The Company enters into standard indemnification arrangements in the ordinary course of business. Pursuant to these arrangements, the Company
indemnifies, holds harmless, and agrees to reimburse the indemnified parties for losses suffered or incurred by the indemnified party, in connection with
any trade secret, copyright, patent or other intellectual property infringement claim by any third-party with respect to the Company’s technology. The term
of these indemnification agreements is generally perpetual. The maximum potential amount of future payments the Company could be required to make
under these agreements is not determinable because it involves claims that may be made against the Company in the future but have not yet been made.

The Company has entered into indemnification agreements with its directors and officers that may require the Company to indemnify its directors
and officers against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct
of the individual.

The Company has not incurred costs to defend lawsuits or settle claims related to these indemnification agreements. No liability associated with such

indemnifications has been recorded to date.

The outstanding debt is related to a term loan entered by the Company with Biopharma Credit Investments IV Sub LP, or Pharmakon, in October
2017 for total loan proceeds of $40.0 million. The total debt issuance costs of $1.3 million were recorded as a direct deduction from the carrying amount of
the term loan on the consolidated balance sheet and are being amortized over the period of the term loan using the effective interest method to interest
expense in the consolidated statement of operations. The term loan includes an interest-only period for 35 months through September 2020 and is then
repaid in equal quarterly principal payments plus interest through December 2022. The New Term Loan is collateralized by all of the Company's assets,
including intellectual property. The term loan carries a fixed interest rate of 11.5% and a closing fee of 1.5% of the funded amount, or $0.6 million. The
term loan includes a pre-payment fee equal to the interest due for the first 30 months of the agreement if it is prepaid within the first 30 months, a 2%
prepayment penalty for months 31-48, and a 1% penalty for months 49-60. The loan is a senior obligation secured with a blanket first lien on the assets of
the Company. The effective interest rate for the year ended December 31, 2019 and 2018 was 12.3% and 12.3%, respectively.

The table below summarizes annual future minimum principal payments under the loan agreement as of December 31, 2019:

The term loan requires the Company to maintain a minimum cash balance of $5.0 million and to achieve certain revenue targets. Beginning with the
first quart of 2019, the Company is required to meet either minimum net sales or trailing 12-month consolidated EBITDA targets. The Company needs to
meet one or the other, but not both. If the Company does not meet either the minimum net sales or trailing 12-month consolidated EBITDA targets, the debt
will immediately become due. The remaining minimum net sales and trailing 12-month consolidated EBITDA targets are as follows:

9. Common and Preferred Stock

The Company's certificate of incorporate as amended and restated in October 2018, authorizes the Company to issue 100,000,000 shares of common
stock and 5,000,000 shares of preferred stock, each having a par value of $0.0001. Common stock issued and outstanding as of December 31, 2019 and
2018 were 25,163,803 shares and 24,450,757 shares, respectively. As of December 31, 2019 and 2018, there was no preferred stock issued and outstanding.
See  “Note  14  -  Subsequent  Events”  in  the  accompanying  Notes  to  Consolidated  Financial  Statements  for  discussions  regarding  issuance  of  additional
common stock through a subsequent public offering.

The  holders  of  common  stock  are  entitled  to  receive  dividends  whenever  funds  are  legally  available,  as,  when,  and  if  declared  by  the  Board  of

Directors. There have been no dividends declared to date.

10. Stock-Based Compensation

2008 Stock Option Plan and 2018 Equity Incentive Plan

In  April  2008,  the  Company  adopted  the  2008  Stock  Option  Plan  (the  "2008  SOP"),  as  amended,  under  which  the  Board  of  Directors  may  issue
incentive and non-qualified stock options to employees, directors and consultants. In October 2018, the Company adopted the 2018 Equity Incentive Plan
(the "2018 EIP"), which serves as the successor to the 2008 SOP, under which the Board of Directors may issue incentive and non-qualified stock options
and RSUs to employees, directors and consultants. No new options have been granted under the 2008 SOP since August 2018. Outstanding options under
the 2008 SOP continue to be subject to the terms and conditions of that plan.

The number of shares of common stock reserved for issuance under the 2018 EIP will automatically increase on January 1 of each year, beginning
January 1, 2019, and continuing through and including January 1, 2028, by 5% of the total number of shares of the Company's capital stock outstanding on
December 31 of the preceding calendar year, or a lesser number of shares determined by the Company's Board of Directors. On January 1, 2019, the total
number  of  shares  of  common  stock  reserved  for  issuance  increased  by  1,222,538  shares.  The  Company  filed  a  Registration  Statement  on  Form  S-8  on
March  22,  2019  to  register  these  additional  shares  reserved  for  issuance  under  the  2018  EIP.  As  of  December  31,  2019,  a  total  of  2,567,295  shares  of
common stock are available for future grants under the 2018 EIP. On January 1, 2020, the total number of shares of common stock reserved for issuance
under the 2018 EIP automatically increased by 1,258,190 shares.

The Board of Directors has the authority to determine to whom options will be granted, the number of shares, the term and the exercise price. If an
individual owns stock representing more than 10% of the outstanding shares, the price of each share shall be at least 110% of the fair market value, as
determined by the Board of Directors. The exercise price of an incentive stock option and a non-qualified stock option shall not be less than 100% and
85%, respectively, of the fair market value on the date of grant.

Options granted have a term of 10 years, except, options granted to individuals holding more than 10% of the outstanding shares have a term of five
years. Options generally vest over a four-year period. Certain shares issued under the Plan are exercisable immediately, but subject to a right of repurchase
by the Company of any unvested shares. RSUs granted under the 2018 Equity Incentive Plan generally vest over two to four years based upon continued
services and are settled at vesting in shares of the Company's common stock.

The aggregate intrinsic value of options exercised during the years ended December 31, 2019 and 2018 amounted to $6.8 million and $3.6 million,
respectively, representing the difference between the fair value of the Company's common stock at the date of exercise and the exercise price paid. The fair
value  of  the  Company's  common  stock  prior  to  the  IPO  was  based  on  the  third-party  valuations  as  determined  by  the  Company's  Board  of  Directors.
Subsequent to IPO, the Company uses market price at for its common stock as reported on the Nasdaq Global Market. The aggregate intrinsic values of
options outstanding, options vested and exercisable, and options vested and expected to vest as of December 31, 2019 represents the difference between the

Early Exercise of Unvested Stock Options

Early exercises of stock options are subject to a right of repurchase by the Company of any unvested shares. The repurchase rights lapse over the
original vesting period of the options. The Company accounts for the cash received in consideration for the early exercised options as a liability included in
accrued liabilities, which is then reclassified to stockholders’ equity (deficit) as the options vest. As of December 31, 2019 and 2018, the Company had a
total of 21,404 and 74,019 shares of common stock, respectively, subject to repurchase under the Plan and $0.1 million and $0.3 million, respectively, of

Employee Stock Purchase Plan

Under  the  Company's  2018  Employee  Stock  Purchase  Plan  (the  "ESPP")  adopted  in  October  2018,  the  Company  allows  eligible  employees  to
purchase shares of the Company's common stock through payroll deductions at the price equal to 85% of the lesser of the fair market value of the stock as
of the first date or the ending date of each six month offering period. There were 515,307 shares of common stock originally reserved for issuance under
the ESPP. Under the ESPP, the number of shares reserved for issuance under the ESPP automatically increases on January 1st of each year, starting on
January  1,  2019,  and  continuing  through  January  1,  2029,  by  an  amount  equal  to  (i)  the  lesser  of  1%  of  the  total  number  of  shares  of  the  Registrant’s
common stock outstanding on December 31st of the preceding calendar year, and (ii) 555,555 shares of common stock. On March 22, 2019, the Company
filed a Registration Statement on Form S-8 to register 244,507 additional shares of common stock for issuance under the ESPP. As of December 31, 2019, a
total of 591,357 shares of common stock are available for future grants under the 2018 EIP. On January 1, 2020, the total number of shares of common

There was no provision for income taxes recorded for the years ended December 31, 2019 and 2018.  The  Company  continues  to  maintain  a  full
valuation allowance against its net deferred tax assets due to the uncertainty surrounding realization of such assets. The Company periodically evaluates the
realizability of its net deferred tax assets based on the expected realization and is dependent on the Company's ability to generate sufficient future taxable
income during periods prior to the expiration of tax attributes to fully utilize these assets.

On December 22, 2017, the U.S. enacted a law commonly known as the Tax Cuts and Jobs Act (the “Act”) which makes widespread changes to the
Internal Revenue Code, including a reduction in the federal corporate tax rate from 35.0% to 21.0%, and move from a worldwide tax system to territorial
system. As a result of the enactment of the Act, during the year ended December 31, 2018, the Company recognized a reduction to its deferred tax assets of
approximately $15.8 million. The reduction to Company's deferred tax assets did not result in the recognition of provision for income taxes as the Company
maintains full valuation allowance on its net deferred tax assets.

available  to  reduce  future  taxable  income,  if  any,  for  federal  and  state  income  tax  purposes,  respectively.  If  not  utilized,  the  Company’s  federal  NOL
carryforward begins to expire in 2028, and the state NOL carryforward begins to expire in 2020.

As of December 31, 2019, the Company had credit carryforwards of approximately $2.1 million and $2.2 million available to reduce future taxable
income,  if  any,  for  both  federal  and  state  income  tax  purposes,  respectively.  The  federal  credits  begin  to  expire  in  2029,  and  the  state  credits  have  no
expiration date.

SI-BONE, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Tax Reform Act of 1986 limits the use of NOL and tax credit carryforwards in certain situations where changes occur in the stock ownership of
a company. In general, if the Company experiences a greater than 50% aggregate change in ownership over a three-year period (a Section 382 ownership
change), utilization of its pre-change NOL carryforwards are subject to an annual limitation under Section 382 of the Internal Revenue Code (California
has similar laws). The annual limitation generally is determined by multiplying the value of the Company’s stock at the time of such ownership change
(subject  to  certain  adjustments)  by  the  applicable  long-term  tax-exempt  rate.  Such  limitations  may  result  in  expiration  of  a  portion  of  the  NOL
carryforwards before utilization. The Company has not utilized any NOL carryovers through December 31, 2019. In addition, the Company’s deferred tax
assets  are  subject  to  full  valuation  allowance,  and  thus  no  benefit  for  deferred  tax  assets  have  been  recorded.  The  Company  has  determined  that  it
experienced Section 382 ownership changes in 2010 and $1.4 million of its NOL carryforwards are limited. The Company also updated its Section 382
ownership change analysis through June 30, 2019, considering the recent changes in ownership following its IPO in October 2018. Based on the result of
the analysis, the Company concluded that it did not undergo ownership change that would require additional limitations on its NOL carryforwards. The
Company further concluded that the equity shift between June 30, 2019 to December 31, 2019 was not material, considering the changes in the outstanding
number  of  shares  at  each  respective  period.  The  Company  will  continually  assess  the  need  to  update  its  Section  382  ownership  change  analysis,  as  the
Company may experience ownership changes in the future that could materially limit its ability to use its NOL carryforwards.

The Company accounts for the uncertainty in income taxes by utilizing a comprehensive model for the recognition, measurement, presentation and
disclosure in financial statements of any uncertain tax positions that have been taken or are expected to be taken on an income tax return. The changes in
the Company’s uncertain income tax positions for the years ended December 31, 2019 and 2018 consisted of the following:

Balance at beginning of the year

Increases related to current year's tax positions

Balance at end of the year

The Company has elected to recognize interest and penalties related to uncertain tax positions as a component of income tax expense. The Company
has no accrued interest related to unrecognized tax benefits as of December 31, 2019 and 2018. None of the Company’s unrecognized tax benefits that, if
recognized, would affect its effective tax rates for the years ended December 31, 2019 and 2018. The Company does not anticipate the total amounts of
unrecognized tax benefits will significantly increase or decrease in the next 12 months.

The Company currently has no federal or state tax examinations in progress nor has it had any federal or state examinations since inception. As a

result of the Company’s net operating loss carry forwards, all of its tax years are subject to federal and state tax examinations.

14. Subsequent Events

Public Offering of Common Stock

Pursuant to the Shelf Registration Statement on Form S-3 which was declared effective by the SEC on January 2, 2020 and the Final Prospectus
Supplement dated January 22, 2020, on January 27, 2020, the Company sold 2,490,053 shares at a follow-on public offering price of $21.50 per share for a
net proceeds of $50.3 million to the Company, after deducting the underwriting discounts and commissions but before offering expenses. Upon completion
of  the  offering  and  issuance  of  common  stock,  the  Company  had  27,708,111  shares  of  common  stock  outstanding.  The  Company  also  granted  the
underwriters  an  option  for  a  period  of  30  days  from  the  date  of  filing  the  prospectus  supplement  to  purchase  up  to  645,000  additional  shares  of  the
Company's common stock at a public offering price of $21.50  per  share.  On  February  24,  2020,  the  underwriters  fully  exercised  its  option  to  purchase
additional  shares  of  the  Company's  common  stock  for  an  additional  net  proceeds  of  $13.0  million  to  the  Company,  after  deducting  the  underwriting
discounts and commissions. The Company intends to use the net proceeds from this offering to support the continued commercial expansion of its iFuse
system, sales and marketing, surgeon training and clinical studies, as well as working capital and general corporate purposes. The Company may also use a
portion  of  the  net  proceeds  to  acquire  or  invest  in  complementary  products,  technologies,  or  businesses;  however,  the  Company  currently  has  no
agreements or commitments to complete any such transactions.

In  addition  to  the  shares  sold  by  the  Company  in  the  public  offering,  on  January 27, 2020,  the  selling  stockholders  sold  1,809,947 shares of the
Company’s  common  stock  previously  held  by  the  selling  shareholders  at  a  price  to  the  public  of  $21.50  per  share.  The  Company  did  not  receive  any
proceeds  from  the  sales  by  the  selling  shareholders.  In  conjunction  with  the  sales  by  the  selling  shareholders,  the  Company  incurred  offering  costs
associated with the selling of shares by the selling shareholders, which will be recognized as transaction costs within general and administrative expenses
on consolidated statement of operations in the first quarter of 2020.

Settlement Agreement

On  January  14,  2020,  the  Company  entered  into  a  definitive  settlement  agreement  related  to  an  outstanding  legal  proceeding.  For  information
regarding this legal proceeding, refer to Legal Proceedings in “Note 6 -  Commitments  and  Contingencies”  in  the  accompanying  Notes  to  Consolidated
Financial Statements.

Joint Development Agreement with a Related Party

On  February  24,  2020,  the  Company  entered  into  a  joint  development  agreement  (the  "Development  Agreement")  with  SeaSpine  Orthopedics
Corporation ("SeaSpine") to develop a next generation device for sacropelvic fixation. Mr. Keith Valentine, who serves as the President, Chief Executive
Officer and a member of the board of directors of SeaSpine, also serves as a member of the Company's Board of Directors since August 2015.

Pursuant to the development Plan, SeaSpine shall use reasonable efforts to assist in the develop of the potential product offering, including licensing
certain existing intellectual property to be incorporated into such product. Under the terms of the Development Agreement, the Company agreed to make
monthly  payments  of  approximately  $10,000  to  SeaSpine  to  reimburse  for  full  time  resources  employed  by  SeaSpine  responsible  to  conduct  the
development activities. Certain intellectual property developed pursuant to the project plan will be owned by the Company, certain intellectual property
developed pursuant to the project plan will be owned by SeaSpine, and other intellectual property developed pursuant to the project plan will be jointly
owned by SeaSpine and the Company. The Company also agreed to provide SeaSpine a royalty-free, worldwide, perpetual, non-exclusive license of certain
of the Company's intellectual property incorporated into the product to be developed. The Company also agreed to pay SeaSpine a product royalty, in an
amount specified in the Development Agreement, for each resulting product sold for a period of 10 years beginning on the initial market launch. The term
of the Development Agreement shall continue until the expiration of all royalty terms, unless earlier terminated by either parties, in situations defined in the
Development Agreement.

Supplementary Data

Selected Quarterly Consolidated Financial Data (Unaudited)

As a "smaller reporting company," we are not required to provide the information required by this Item.

Schedule II - Valuation and Qualifying Accounts

All schedules are omitted because they are not applicable, or the required information is shown in the financial statements or notes thereto.

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 the reports that we file or
submit under the Securities and Exchange Act of 1934 is (i) recorded, processed, summarized and reported within the time periods specified in the SEC’s
rules and forms and (ii) accumulated and communicated to our management, including our principal executive officer and principal financial officer, to
allow timely decisions regarding required disclosure.

The effectiveness of any system of internal control over financial reporting, including ours, is subject to inherent limitations, including the exercise of
judgment  in  designing,  implementing,  operating,  and  evaluating  the  controls  and  procedures,  and  the  inability  to  eliminate  misconduct  completely.
Accordingly,  any  system  of  internal  control  over  financial  reporting,  including  ours,  no  matter  how  well  designed  and  operated,  can  only  provide
reasonable, not absolute assurances. In addition, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may
become  inadequate  because  of  changes  in  conditions,  or  that  the  degree  of  compliance  with  the  policies  or  procedures  may  deteriorate.  We  intend  to
continue to monitor and upgrade our internal controls as necessary or appropriate for our business but cannot assure you that such improvements will be
sufficient to provide us with effective internal control over financial reporting.

As of December 31, 2019, our management, with the participation of our Chief Executive Officer ("CEO") and our Chief Operating Officer & Chief
Financial Officer ("COO/CFO"), have evaluated our disclosure controls and procedures (as defined in Rules 13a‑15(e) and 15d‑15(e) under the Securities
Exchange Act of 1934, as amended). Based on that evaluation, our CEO and our COO/CFO have concluded that, as of December 31, 2019, our disclosure
controls and procedures were effective at the reasonable assurance level.

Internal Control over Financial Reporting

Management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting  for  the  Company.  Our  management
assessed the effectiveness of our internal control over financial reporting as of December 31, 2019. In making this assessment, our management used the
criteria set forth in the Internal Control -Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission
(COSO). Based on management's assessment, management has concluded that, as of December 31, 2019, our internal control over financial reporting was
effective.

This  Annual  Report  does  not  include  an  attestation  report  of  our  independent  registered  public  accounting  firm  regarding  internal  control  over
financial  reporting.  Management’s  report  was  not  subject  to  attestation  by  our  independent  registered  public  accounting  firm  because  as  an  “emerging
growth company” we are exempt from Section 404(b) of the Sarbanes-Oxley Act of 2002.

Changes in Internal Control Over Financial Reporting.

There  were  no  changes  in  our  internal  control  over  financial  reporting  during  the  fourth  quarter  of  the  year  ended  December  31,  2019,  that  have

materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

DESCRIPTION OF SI-BONE, INC. COMMON STOCK

Exhibit 4.3

Our authorized capital stock consists of 100,000,000 shares of common stock, $0.0001 par value per share, and 5,000,000 shares of preferred stock,
$0.0001  par  value  per  share.  A  description  of  our  common  stock  and  the  material  terms  and  provisions  of  our  certificate  of  incorporation  and  bylaws
affecting the rights of holders of our common stock is set forth below. The description is intended as a summary, and is qualified in its entirety by reference
to our certificate of incorporation and the bylaws.

Common Stock

Dividend Rights

Subject to preferences that may apply to shares of preferred stock outstanding at the time, the holders of outstanding shares of our common stock are
entitled to receive dividends out of funds legally available if our board of directors, in its discretion, determines to issue dividends and only then at the
times and in the amounts that our board of directors may determine.

Voting Rights

The holders of our common stock are entitled to one vote per share. Stockholders do not have the ability to cumulate votes for the election of directors.
Our  amended  and  restated  certificate  of  incorporation  and  amended  and  restated  bylaws  provide  for  a  classified  board  of  directors  consisting  of  three
classes  of  approximately  equal  size,  each  serving  staggered  three-year  terms.  Only  one  class  of  directors  will  be  elected  at  each  annual  meeting  of  our
stockholders, with the other classes continuing for the remainder of their respective three-year terms.

No Preemptive or Similar Rights

Our common stock is not entitled to preemptive rights and is not subject to conversion, redemption, or sinking fund provisions.

Right to Receive Liquidation Distributions

Upon our dissolution, liquidation or winding-up, the assets legally available for distribution to our stockholders are distributable ratably among the
holders  of  our  common  stock,  subject  to  prior  satisfaction  of  all  outstanding  debt  and  liabilities  and  the  preferential  rights  and  payment  of  liquidation
preferences, if any, on any outstanding shares of preferred stock.

Anti-takeover Effects of Provisions of our Certificate of Incorporation and Bylaws and Delaware Law

Delaware Law

We are governed by the provisions of Section 203 of the Delaware General Corporation Law regulating corporate takeovers. This section prevents
some Delaware corporations from engaging, under some circumstances, in a business combination, which includes a merger or sale of at least 10% of the
corporation’s assets with any interested stockholder, meaning a stockholder who, together with affiliates and associates, owns or, within three years prior to
the determination of interested stockholder status, did own 15% or more of the corporation’s outstanding voting stock, unless:

•

•

•

the transaction is approved by the board of directors prior to the time that the interested stockholder became an interested stockholder;

upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at
least 85% of the voting stock of the corporation outstanding at the time the transaction commenced, excluding for purposes of determining the
voting stock outstanding (but not the outstanding voting stock owned by the interested stockholder) those shares owned (i) by persons who are
directors and also officers and (ii) employee stock plans in which employee participants do not have the right to determine confidentially whether
shares held subject to the plan will be tendered in a tender or exchange offer; or

subsequent to such time that the stockholder became an interested stockholder the business combination is approved by the board of directors and
authorized at an annual or special meeting of stockholders by at least two-thirds of the outstanding voting stock which is not owned by the
interested stockholder.

A Delaware corporation may “opt out” of these provisions with an express provision in its original certificate of incorporation or an express

provision in its certificate of incorporation or amended and restated bylaws resulting from a stockholders’ amendment approved by at least a majority of the
outstanding voting shares. We have not opted out of these provisions. As a result, mergers or other takeover or change in control attempts of us may be
discouraged or prevented.

Certificate of Incorporation and Bylaws Provisions

Our amended and restated certificate of incorporation and our amended and restated bylaws include a number of provisions that may have the effect of

deterring hostile takeovers or delaying or preventing changes in control of our management team, including the following:

•

•

•

•

•

Board of Directors Vacancies.  Our  amended  and  restated  certificate  of  incorporation  and  amended  and  restated  bylaws  authorize  our  board  of
directors to fill vacant directorships, including newly-created seats. In addition, the number of directors constituting our board of directors is set
only by resolution adopted by a majority vote of our entire board of directors. These provisions prevent a stockholder from increasing the size of
our board of directors and gaining control of our board of directors by filling the resulting vacancies with its own nominees.

Classified Board. Our amended and restated certificate of incorporation and amended and restated bylaws provide that our board of directors is
classified into three classes of directors, each of whom will hold office for a three-year term. In addition, directors may only be removed from the
board  of  directors  for  cause  and  only  by  the  approval  of  a  majority  of  our  then-outstanding  shares  of  our  common  stock.  The  existence  of  a
classified board could delay a successful tender offeror from obtaining majority control of our board of directors, and the prospect of that delay
might deter a potential offeror.

Stockholder Action; Special Meeting of Stockholders. Our amended and restated certificate of incorporation provides that stockholders are not able
to take action by written consent, and are only be able to take action at annual or special meetings of our stockholders. Stockholders are not be
permitted  to  cumulate  their  votes  for  the  election  of  directors.  Our  amended  and  restated  bylaws  further  provide  that  special  meetings  of  our
stockholders may be called only by a majority vote of our entire board of directors, the chairman of our board of directors, or our chief executive
officer.

Advance  Notice  Requirements  for  Stockholder  Proposals  and  Director  Nominations.  Our  amended  and  restated  bylaws  provide  advance  notice
procedures  for  stockholders  seeking  to  bring  business  before  our  annual  meeting  of  stockholders,  or  to  nominate  candidates  for  election  as
directors at any meeting of stockholders. Our amended and restated bylaws also specify certain requirements regarding the form and content of a
stockholder’s notice. These provisions may preclude our stockholders from bringing matters before our annual meeting of stockholders or from
making nominations for directors at our meetings of stockholders.

Issuance of Undesignated Preferred Stock. Our board of directors have the authority, without further action by the holders of common stock, to
issue up to 5,000,000 shares of undesignated preferred stock with rights and preferences, including voting rights, designated from time to time by
the board of directors. The existence of authorized but unissued shares of preferred stock enable our board of directors to render more difficult or
to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest, or otherwise.

Choice of Forum

Our amended and restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for any
derivative action or proceeding brought on our behalf; any action asserting a breach of fiduciary duty by any director, officer, or other employee to us or
our stockholders; any action asserting a claim against us arising pursuant to the Delaware General Corporation Law, our amended and restated certificate of
incorporation or our amended and restated bylaws, or any action asserting a claim against us or any director or officer or other employee that is governed
by the internal affairs doctrine. The provision does not apply to suits brought to enforce a duty or liability created by the Exchange Act. The enforceability
of similar choice of forum provisions in other companies’ certificates of incorporation has been challenged in legal proceedings, and it is possible that a
court could find these types of provisions to be inapplicable or unenforceable. Our amended and restated certificate of incorporation further provides that
the federal district courts of the United States of America is the exclusive forum for resolving any complaint asserting a cause of action arising under the
Securities Act. We do not currently intend to enforce the federal forum selection provision unless a recent Delaware Chancery Court decision invalidating
such a clause is appealed and the Delaware Supreme Court reverses the decision.

2019 Non-Employee Directors’ Compensation Policy
Approved by the Board of Directors
June 13, 2019

Exhibit 10.36

Each member of the Board of Directors (the “Board”) who is not also serving as an employee of SI-BONE, Inc. (the “Company”) or any of its
subsidiaries (each such member, an “Eligible Director”) will receive the compensation described in this Non-Employee Directors’ Compensation Policy
(the “Director Compensation Policy”) for his or her Board service. The Director Compensation Policy may be amended at any time in the sole discretion
of the Board or the Compensation Committee of the Board.

Annual Cash Compensation

Each Eligible Director shall receive the cash compensation described below. The annual cash compensation amount set forth below is payable in
equal quarterly installments, payable in arrears on the last day of each fiscal quarter in which the service occurred. If an Eligible Director joins the Board or
a committee of the Board (“Committee”) at a time other than effective as of the first day of a fiscal quarter, each annual retainer set forth below will be pro-
rated based on days served in the applicable fiscal year, with the pro-rated amount paid for the first fiscal quarter in which the Eligible Director provides the
service, and regular full quarterly payments thereafter. All annual cash retainer fees are vested upon payment.

1.

Annual Board Service Retainer:
a.    Eligible Directors: $40,000

2.    Annual Committee Member / Chair Service Retainer:

a.    Member / Chairperson of the Audit Committee: $9,000 / $20,000
b.    Member / Chairperson of the Compensation Committee: $6,000 / $15,000
c.    Member / Chairperson of the N&CG Committee: $5,000 / $10,000

3.

Annual Lead Independent Director Service Retainer:
a.    Lead Independent Director: $27,500

Equity Compensation

The  equity  compensation  set  forth  below  will  be  granted  under  the  SI-BONE,  Inc.  2018  Equity  Incentive  Plan  (the  “Plan”),  and  will  be
documented on the applicable form of equity award agreement most recently approved for use by the Board (or a duly authorized committee thereof) for
Eligible Directors. All stock options granted under the Director Compensation Policy will be nonstatutory stock options, with an exercise price per share
equal to 100% of the Fair Market Value (as defined in the Plan) of the underlying Common Stock on the date of grant, and a term of ten years from the date
of grant (subject to earlier termination in connection with a termination of service as provided in the Plan).

1.    Initial Option Grant: Upon first election to the Board, each Eligible Director will be granted, upon approval by the Board or Compensation Committee
of the Board, a stock option to purchase 26,236 shares of Common Stock (the “Initial Option Grant”). The Initial Option Grant will vest monthly over
three years, such that the Initial Option Grant will be fully vested on the third anniversary of the Eligible Director’s first election to the Board, subject to the
Eligible Director’s Continuous Service on each applicable vesting date. In addition, in the event of a Change in Control or a Corporate Transaction, any
unvested portion of the Initial Option Grant will fully vest and become exercisable as of immediately prior to the effective time of such Change in Control
or Corporate Transaction, subject to the Eligible Director’s Continuous Service on the effective date of such transaction.

2.    Additional Option Grants: The Compensation Committee may review and approve additional equity grants to Eligible Directors on the date of each
subsequent annual meeting. Each Eligible Director shall receive an annual option grant of 15,741 shares of Common Stock which will vest monthly over
one year from the grant date (the “Annual Option Grant”), such that the Annual Option Grant will be fully vested on the first anniversary of the date of
grant, subject to the Eligible Director’s Continuous Service on each applicable vesting date. In addition, in the event of a Change in Control or a Corporate
Transaction, any unvested portion of the Annual Option Grant will fully vest and become exercisable as of immediately prior to the effective time of such
Change in Control or Corporate Transaction, subject to the Eligible Director’s Continuous Service on the effective date of such transaction.

 
Philosophy

The Director Compensation Policy is designed to attract and retain experienced, talented individuals to serve on the Board. The Board anticipates
that  the  Board,  or  a  duly  authorized  committee  thereof,  will  generally  review  Eligible  Director  compensation  on  an  annual  basis.  The  Director
Compensation Policy, as amended from time to time, may take into account the time commitment expected of Eligible Directors, best practices and market
rates in director compensation, the economic position of the Company, broader economic conditions, historical compensation structure, the advice of the
compensation consultant that the Compensation Committee or the Board may retain from time to time, and the potential dilutive effect of equity awards on
our stockholders.

Under  the  Director  Compensation  Policy,  Eligible  Directors  receive  cash  compensation  in  the  form  of  retainers  to  recognize  their  level  of
responsibility  as  well  as  the  necessary  time  commitment  involved  in  serving  in  a  leadership  role  and/or  on  Committees.  Eligible  Directors  also  receive
equity compensation because we believe that stock ownership provides an incentive to act in ways that maximize long-term stockholder value. Further, we
believe that stock-based awards are essential to attracting and retaining talented Board members. When stock options are granted, these stock options will
have an exercise price at least equal to the Fair Market Value of Common Stock on the date of grant, so that stock options provide a return only if the Fair
Market Value appreciates over the period in which the stock option vests and remains exercisable. We believe that the vesting acceleration provided in the
case  of  a  Change  in  Control  or  other  Corporate  Transaction  is  consistent  with  market  practices  and  is  critical  to  attracting  and  retaining  high  quality
directors.
