ANNUAL REPORT

TO OUR SHAREHOLDERS AND COLLEAGUES:

In 2016, The Lipid Management Team at Esperion focused on building 
a strong foundation for the global pivotal Phase 3 LDL-cholesterol 
lowering program for bempedoic acid, which the team successfully 
initiated on time, including initiation of the CLEAR Outcomes 
cardiovascular outcomes trial (CVOT).  While small in number, our 
highly-experienced, determined team made tremendous progress 
over the past year advancing our two Phase 3 therapies; bempedoic 
(cid:2)(cid:3)(cid:4)(cid:5)(cid:6)(cid:2)(cid:7)(cid:5)(cid:6)(cid:8)(cid:9)(cid:10)(cid:6)(cid:5)(cid:11)(cid:12)(cid:13)(cid:14)(cid:10)(cid:8)(cid:15)(cid:16)(cid:4)(cid:14)(cid:14)(cid:6)(cid:17)(cid:18)(cid:19)(cid:10)(cid:5)(cid:6)(cid:5)(cid:11)(cid:20)(cid:10)(cid:6)(cid:3)(cid:11)(cid:21)(cid:13)(cid:4)(cid:7)(cid:2)(cid:8)(cid:4)(cid:11)(cid:7)(cid:22)(cid:6)(cid:3)(cid:11)(cid:21)(cid:13)(cid:4)(cid:7)(cid:4)(cid:7)(cid:23)(cid:6)
bempedoic acid + ezetimibe (BA+EZ). 

Performance excellence resulted in the achievement of several 
important development program milestones this past year:

JANUARY
-    Launched the global pivotal Phase 3 clinical development program 
for bempedoic acid with the initiation of the long-term safety and 
tolerability study (Study 1). 

-    Initiated a Phase 2 pharmacokinetics/pharmacodynamics  
(PK/PD) clinical study (1002-035) of bempedoic acid in  
patients treated with background atorvastatin 80 mg, the  
most commonly prescribed high-dose statin.

-    Published full results from the previously completed 1002-008 
study, “Treatment with ETC-1002 alone and in combination with 
ezetimibe lowers LDL-cholesterol in hypercholesterolemic  
patients with or without statin intolerance,” in the Journal of  
Clinical Lipidology.

FEBRUARY

-    Initiated a Phase 1 clinical pharmacology study (1002-037) to 

assess the safety and tolerability of bempedoic acid, as well as the

or implied by the forward-looking statements.

The words ‘‘anticipate,’’ ‘‘believe,’’ ‘‘estimate,’’ ‘‘expect,’’ ‘‘intend,’’ ‘‘may,’’ ‘‘plan,’’ ‘‘predict,’’
‘‘project,’’ ‘‘target,’’ ‘‘potential,’’ ‘‘will,’’  ‘‘would,’’ ‘‘could,’’ ‘‘should,’’ ‘‘continue,’’ and similar expressions
are intended to identify forward-looking  statements, although  not  all forward-looking statements
contain these identifying words. These forward-looking  statements include, among other things,
statements about:

• our ability to obtain regulatory approval for bempedoic acid, including statements related to

specific clinical studies or clinical observations that will be required for  such approval;

• our ability to achieve clinical or regulatory milestones with our existing cash resources;

• the design, timing or outcome of our Phase 3 clinical program of bempedoic acid;

• the design, timing or outcome of our cardiovascular  outcomes trial, or  CVOT,  of bempedoic

acid;

• the design, timing or outcome of our other clinical  studies of bempedoic  acid;

• our ability to recruit and enroll patients,  particularly ‘‘statin  intolerant’’ patients, in any ongoing

or future clinical study;

• our ability to replicate positive results from a  completed clinical  study in  a future clinical study;

• our ability to fund our development programs with existing capital or  our ability  to  raise

PART I

Item 1. Business

Overview

We  are the lipid management company,  a late-stage  pharmaceutical company focused on

developing  and commercializing convenient, complementary,  cost-effective, once-daily, oral therapies
for the treatment of patients with elevated LDL-C. Through scientific and clinical  excellence,  and a
deep understanding of cholesterol biology, the experienced lipid  management team at  Esperion is
committed to developing new LDL-C  lowering  therapies that will make  a  substantial impact on
reducing global cardiovascular disease, or CVD; the leading cause of death around the  world. With a
targeted mechanism of action, bempedoic acid, our lead product  candidate, is  a first-in-class, orally
available, once-daily ATP-citrate lyase, or  ACL, inhibitor that  reduces cholesterol biosynthesis  and
lowers elevated levels of LDL-C by up-regulating  the LDL receptor,  but with  reduced  potential for
muscle-related side effects. In addition to bempedoic  acid as monotherapy, we  are also  developing
bempedoic  acid in a fixed dose combination with  ezetimibe, an approved, non-statin, oral, LDL-C
lowering therapy.

The clinical development program for  bempedoic acid consists of two major components:  1)  the
global  pivotal Phase 3 LDL-C lowering  program in high CVD  risk patients with hypercholesterolemia
on optimized background lipid-modifying therapy, including maximally tolerated statins,  and patients
who are only able to tolerate less than the lowest approved daily starting dose  of  their  statin  and are
considered ‘‘statin intolerant,’’ and 2)  the global CVOT—known  as Cholesterol Lowering via
BEmpedoic Acid, an ACL-inhibiting Regimen (CLEAR) Outcomes, in patients with
hypercholesterolemia and high CVD  risk and who are considered ‘‘statin  intolerant’’. We initiated our
global  Phase 3 clinical development program in January 2016, with  the 52-week global pivotal  Phase 3
long-term safety and tolerability study  (Study 1), and  initiated the  three remaining global pivotal
LDL-C lowering efficacy studies in December  2016. We  expect  to  report top-line  results from  our
global  Phase 3 program in its entirety by mid-2018, and intend  to  use positive results  from our  Phase 3
program to support our submissions  for an  LDL-C  lowering  indication in  the U.S.  and Europe by the
first half of 2019. We also initiated the CLEAR Outcomes CVOT in December 2016,  and intend to use
positive results from this CVOT to support our submissions for  a  CV risk  reduction indication in the
U.S. and Europe by 2022.

We  believe that bempedoic acid, if approved, has  the potential to become a convenient and
complementary oral therapy to significantly  reduce elevated levels  of LDL-C in patients inadequately
treated with current lipid-modifying therapies. It  is estimated that 40 million patients in the  U.S. are
taking statins, with approximately 5-20  percent  of  these patients only able to tolerate less than the
lowest approved daily starting dose of  their  statin and  considered ‘‘statin intolerant’’.

We  were founded  in January 2008, by former executives of and investors  in the original Esperion

Therapeutics, Inc., a biopharmaceutical  company which was primarily  focused  on the  research  and
development of therapies to regulate high-density lipoprotein, or HDL. The  original  Esperion was
acquired by Pfizer Inc. in 2004. Bempedoic  acid was first discovered at the  original  Esperion and we
subsequently acquired the rights to the product from  Pfizer in 2008. We own the exclusive worldwide
rights to bempedoic acid.

Bempedoic  Acid

With a targeted mechanism of action, bempedoic  acid is a  first-in-class, orally available, once-daily

ACL inhibitor that reduces cholesterol  biosynthesis and lowers elevated  levels of LDL-C by
up-regulating the LDL receptor, but with reduced potential for muscle-related side effects.  Completed
Phase 1 and 2 studies in more than 800  patients  treated with bempedoic acid  have produced clinically
relevant LDL-C lowering results of up to 30 percent as monotherapy, approximately 50 percent  in
combination with ezetimibe, and an incremental 20+  percent when added to stable statin  therapy.

Mechanism of Action

In November 2016, we announced the publication of ‘‘Liver-specific ATP-citrate lyase  inhibition by

bempedoic  acid decreases LDL-C and attenuates atherosclerosis,’’ by Stephen  L. Pinkosky, our
Associate Director of Translational Research and Biology,  et al., in Nature Communications. The paper
systematically outlines the experiments and analyses undertaken by us and our collaborators to fully
understand the mechanism of action  for  how  bempedoic acid reduces LDL-C, including its specificity
for the liver. Bempedoic acid is a prodrug that  once activated, inhibits  ACL, an enzyme upstream of
HMG-CoA reductase (the molecular  target of statins) in the  cholesterol  synthesis pathway. Like statins,
bempedoic  acid decreases cholesterol synthesis  in the liver, which results in decreased intracellular
cholesterol, up-regulation of LDL receptor activity  and increased LDL-C  clearance  from the blood.
Although bempedoic acid and statins both inhibit cholesterol synthesis in the liver, an  important
differentiating feature is that, unlike statins, bempedoic acid is  inactive  in skeletal muscle. Specifically,
bempedoic  acid is a prodrug which requires  activation  by a specific enzyme,  very long-chain  acyl-CoA
synthetase, or ACSVL1, to convert bempedoic acid to its CoA activated form. This enzyme is  present
in the liver but not in skeletal muscle.  Therefore, bempedoic acid  does not inhibit the cholesterol
biosynthesis pathway in skeletal muscle,  thus  providing  a mechanistic  basis for reduced potential for
muscle-related adverse effects. Bempedoic acid  has been shown to provide incremental lowering  of
LDL-C when used in combination with  both ezetimibe and statins at all doses.

Fixed Dose Combination Bempedoic Acid and  Ezetimibe  (BA+EZ)

In the second quarter of 2016, the Food and Drug Administration,  or FDA, accepted  our
submission of an Investigational New Drug, or IND,  application  for the  fixed  dose combination  of
bempedoic  acid 180 mg and ezetimibe  10 mg, or BA+EZ, which  is in development for  the same
indications as bempedoic acid monotherapy (LDL-C lowering and CV risk  reduction). We recently
completed a bioavailability study and a  formulation of BA+EZ has been selected for manufacturing,
development and, if approved, commercialization. We expect to announce  clinical development and
regulatory plans for BA+EZ in the first half of 2017.

Cardiovascular Disease and Elevated LDL-C

Cardiovascular disease, which results  in heart attacks, strokes and other cardiovascular events,
represents the number one cause of  death and disability in  western societies.  The American Heart
Association, or AHA, estimates that approximately 800,000 deaths  in the United  States were  caused by
cardiovascular disease in 2013.

Elevated LDL-C is well-accepted as a  significant risk factor  for cardiovascular disease and the
CDC  estimates that 78 million U.S. adults have elevated levels  of LDL-C.  A consequence of elevated
LDL-C is atherosclerosis, which is a disease  that is characterized  by the deposition of excess cholesterol
and other lipids in the walls of arteries  as plaque. The development of  atherosclerotic plaques often
leads to cardiovascular disease. The risk  relationship between  elevated LDL-C and cardiovascular
disease was first defined by the Framingham Heart Study, which commenced  in 1948 to define the
factors that contributed to the development of cardiovascular  disease. The study enrolled participants

5

who did not have any form of cardiovascular  disease and followed them over a long  period of time.
Elevated LDL-C was identified early  on  as key risk factor for the eventual development of
cardiovascular disease.

The hypothesis that lowering elevated  levels of LDL-C would  translate into reduced risk  of

cardiovascular disease was first proven  in  1984 with  the publication  of  the Lipid Research Clinics
Coronary Primary Prevention Trial. In  this  study, treatment with  cholestyramine, a  bile acid  sequestrant,
showed  a 20% reduction in LDL-C and, importantly, a 19% reduction  in risk of cardiovascular disease
death or nonfatal myocardial infarction,  or heart attack. This was the  first major clinical study  to
demonstrate a direct relationship between lowering LDL-C levels and reduced risk of major
cardiovascular events.

The first marketed statin, lovastatin, was approved for use in the  United States in  1987 as a
therapy to lower elevated LDL-C levels.  That  same year,  the  National Cholesterol Education Program
issued its first guidelines for the diagnosis and  treatment of patients with  elevated  LDL-C. Over the
subsequent 22 years, seven more statins were approved for use to lower elevated LDL-C levels.

In 1994 the first clinical outcomes study with a statin was  published. This study demonstrated a

significant reduction in risk for total mortality and major cardiovascular events. A series  of additional
clinical outcomes studies with statins  have each shown that  lowering elevated LDL-C translated  into
reduced risk for major cardiovascular events.  The relationship between the extent  of LDL-C lowering
and reduction in cardiovascular risk appeared to be linear, which  has supported a hypothesis that lower
LDL-C is better for cardiovascular risk. This hypothesis  was tested  and proven in  the TNT (Treating to
New Targets) study where an on-treatment LDL-C level  of 77 mg/dL  associated with  80 mg of
atorvastatin treatment translated into a statistically  significant  22% reduction  in risk of major
cardiovascular events as compared with the 101  mg/dL on-treatment LDL-C level  associated with
10 mg of atorvastatin.

In November 2014, the results of the IMPROVE-IT (IMProved  Reduction of Outcomes: Vytorin
Efficacy International Trial) study were  presented at  the Scientific  Sessions of the  AHA. 18,144 patients
with acute coronary syndrome were enrolled  in IMPROVE-IT and  were randomized  to  receive either
40 mg of simvastatin or 10 mg of ezetimibe/40 mg  of simvastatin,  and  were followed until
> 5,250 events (cardiovascular death,  heart attack, documented  unstable angina requiring
hospitalization, coronary revascularization or  stroke) occurred. The addition of ezetimibe to simvastatin
resulted in a 6.4% relative risk reduction (p=0.016)  in the  aggregate of the events described above.
This was the first study to demonstrate incremental clinical  benefit  with a  non-statin when added  to a
statin.

The direct relationship between lower LDL-C levels and reduced risk for major  cardiovascular

events has been consistently demonstrated in 18  clinical studies completed over the last 28 years
involving more than 90,000 patients.  As a result, physicians  are  highly focused on lowering LDL-C
levels in their patients, and we believe there is a trend  towards even more aggressive LDL-C lowering.
For example, in the United States, increased  attention has  been placed on aggressive LDL-C
management by organizations such as  the National Cholesterol Education  Program, or NCEP, the AHA

6

and the American College of Cardiology, or ACC. Additionally,  both the Canadian Cardiovascular
Society and the Joint British Societies  have supported even lower LDL-C treatment targets  for
high-risk patients. This has led to the  combination  of statins with other  treatments, such  as ezetimibe.

In July 2004, the NCEP issued an update to its Adult Treatment Panel III clinical practice
guidelines on cholesterol management, advising physicians to consider new, more intensive  treatment
options for people at very high risk, high risk and moderately high  risk  for cardiovascular disease. The
LDL-C goals in these updated clinical  practice guidelines, which  are presented below, contemplate
initiating drug therapy at lower LDL-C thresholds, thus  expanding the number of potential patients for
LDL-C lowering therapy.

In November 2013, the American College of Cardiology, or ACC, and the AHA issued new
guidelines for the treatment of elevated  cholesterol. For the  first time in more than  20 years, the new
guidelines do not include specific, numerical LDL-C treatment goals for patients with elevated LDL-C.
However, the guidelines strongly recommend the  use of more  potent statins and intensive statin  therapy
in patients with elevated LDL-C. The new guidelines  also significantly expanded the number of patients
eligible for  statin therapy, including patients  with a history of cardiovascular disease including  stroke,
patients with both Type 1 and Type 2  diabetes, all patients with  LDL-C (cid:2) 190 mg/dL and patients with
a 10-year risk of > 7.5% of developing  cardiovascular disease. Also for the first time,  the guidelines
acknowledge the existence of ‘‘statin  intolerance’’,  and  incorporate ‘‘statin  intolerance’’ into the
consideration of treatment choices and  into  the evaluation of statin  safety.

Other organizations continue to utilize goals  of treatment in their guidelines. The National Lipid

Association, or NLA, guidelines established < 100 mg/dL as the LDL-C  goal of treatment  for patients
at low, moderate and high risk. Patients considered to be at very high risk have a  goal of < 70 mg/dL
of LDL-C. The International Atherosclerosis Society has recommended optimal LDL-C levels  of
< 100 mg/dL for patients who have not had  a cardiovascular event, and < 70 mg/dl for patients who
have had a cardiovascular event.

Other Approved Therapies for Specific Populations

A small subpopulation of patients with extremely  elevated levels  of LDL-C, estimated to be
approximately 300 patients in the U.S., suffer from homozygous  familial  hypercholesterolemia,  or
HoFH. HoFH is a serious and rare genetic disease  and patients with HoFH lack or  have dysfunctional
LDL-receptors and cannot remove LDL-particles  and LDL-C from the blood. As a result,  untreated
HoFH patients typically have  LDL-C levels in the  range  of 450 mg/dL to 1,000  mg/dL.  Microsomal
triglyceride transfer protein, or MTP inhibitors, a PCSK9 inhibitor and an ApoB antisense
oligonucleotide are approved therapies  to  lower  elevated LDL-C  levels in patients with  a clinical  or
laboratory diagnosis of HoFH. Given the  serious safety concerns with the MTP inhibitor  and ApoB
antisense oligonucleotide, specifically hepatotoxicity,  the  FDA  has restricted their usage  to  this  narrow
subpopulation.

Statin Therapy

Statins are the standard of care for patients with hypercholesterolemia today and  are highly
effective at lowering LDL-C. This class of drugs includes  atorvastatin calcium, marketed as Lipitor(cid:4),
the most prescribed LDL-C lowering  drug in the world  and the best-selling pharmaceutical  drug  in
history. Approximately 25% of Americans  over the age of  45 from  2005 to 2008 were treated for
elevated  LDL-C levels with statin therapy,  according to a National Health and Nutrition  Examination
Survey.

Statins are selective, competitive inhibitors  of  HMG-CoA reductase,  a  rate-limiting enzyme in  the

cholesterol biosynthesis pathway, and  work  primarily in liver cells.  Statin inhibition of cholesterol
synthesis increases the number of LDL  receptors  on the  surface of liver cells.  This increase in LDL
receptors increases uptake of LDL particles into liver cells  from the blood, thus lowering  LDL-C levels.
Statins are also thought to have the potential  to  inhibit  cholesterol synthesis in  skeletal muscle. This
inhibition could be linked to the myalgia associated with  statin use as seen  in patients with  ‘‘statin
intolerance’’.

The benefits of statin use in lowering  LDL-C levels  and  improving cardiovascular outcomes are
well documented. Despite the effectiveness  of statins and their  broad market acceptance, there  is a
significant  subset of patients who are unable  to  tolerate statins  due to muscle  pain or  weakness,
memory loss or increased glucose levels, or who are otherwise  unable  to reach  their  LDL-C goal  on
statin therapy alone. In rare but extreme cases, statins  can  lead to muscle breakdown,  kidney failure
and death. In addition, the FDA has recently warned that statins can cause hyperglycemia, an increase
in blood sugar levels and create an increased risk  of worsening of  glycemic control and  of new onset
diabetes. There are approximately 36 million U.S. adults  with  elevated LDL-C levels who are not on an
LDL-C lowering therapy. For these reasons, we believe there is  a need  for  new therapies to treat
patients with elevated LDL-C.

Patients with Heterozygous Familial Hypercholesterolemia  (HeFH) and/or Atherosclerotic Cardiovascular

Disease (ASCVD) who need additional  lowering  of LDL-C—Market Opportunity for Bempedoic Acid  and
BA+EZ

We  are pursuing the development of  bempedoic acid and BA+EZ as an add-on to maximally
tolerated statin therapy for patients with HeFH  and/or ASCVD who  require additional  lowering of
LDL-C. The severity of elevated LDL-C  in these patients, their level of CVD risk  and their therapeutic
options, including those patients only able to tolerate less than the  lowest approved daily  starting dose
of their statin and are considered to be ‘‘statin  intolerant’’, all vary widely.

Patients with ASCVD and persistently elevated LDL-C despite maximally  tolerated statin therapy
represent a large population with important unmet medical  needs.  In a retrospective analysis of United
States data, approximately one-third of high-risk patients treated with  statin monotherapy  for more

9

than three months failed to achieve LDL-C  target levels  of < 100mg/dL, and more than three-quarters
did not achieve the more stringent goal  of < 70  mg/dL.  Data from the TNT study showed that patients
treated with 80 mg of atorvastatin daily  demonstrated  a major cardiovascular event rate of 8.7%  despite
having achieved mean LDL-C levels of 77 mg/dL. In this study, the higher-intensity atorvastatin 80 mg
regimen lowered both LDL-C and cardiovascular events to  a greater extent than the lower-intensity
atorvastatin 10 mg regimen. These findings, among others, suggest that residual  risk may  be  due  to
residual hyperlipidemia.

This has prompted the study of non-statin therapies as  add-on treatment to statins for incremental
reductions in LDL-C and CVD risk. The injectable PCSK9 inhibitors were recently granted approval  in
the United States as an adjunct to maximally tolerated  statin therapy for patients in  these populations
that require additional lowering of LDL-C.

Within the ACVD and HeFH patient  populations there  are patients  whose maximally tolerated
dose of a statin may be no statin at all. These are patients  who  are considered to ‘‘statin intolerant’’.

Muscle pain or weakness is the most common  side effect experienced by statin users  and the  most

common cause for discontinuing therapy.  Moreover, a  significant proportion  of patients remain on
statin therapy despite experiencing muscle-related  side effects.  Accordingly,  we believe  that  in the
presence of a safe and effective complementary non-statin, oral, once-daily, small molecule  LDL-C
lowering therapy, the ‘‘statin intolerant’’ market could grow substantially.

Recently Approved Therapies

PCSK9 Inhibitors

A number of larger biopharmaceutical  companies have  developed, or are  currently  developing, a
new class of biologic therapies that target proprotein convertase subtilisin kexin type  9, or PCSK9,  an
enzyme involved in the degradation of  LDL receptors. These PCSK9 inhibitors  are injectable,
monoclonal antibodies that were evaluated as potential  therapies to lower LDL-C.  In 2015 the FDA
approved two PCSK9 inhibitors: alirocumab,  which was  developed  by Sanofi and Regeneron
Pharmaceuticals and evolocumab, which was developed by Amgen, Inc. These therapies were  approved
as an adjunct to diet and maximally tolerated statin therapy  for patients with HeFH  or ASCVD that
require additional lowering of LDL-C. Additionally, evolocumab was approved as an adjunct to diet
and other LDL-C lowering therapies  for  patients with HoFH. In 2016, Pfizer  discontinued development
of its PCSK9 inhibitor, bococizumab,  due to unanticipated attenuation of  LDL-C lowering over  time in
its  Phase 3 studies. In February 2017, Amgen announced top-line  results for the FOURIER (Further
Cardiovascular OUtcomes Research with PCSK9  Inhibition  in Subjects  with Elevated Risk) CVOT
where  evolocumab significantly reduced  the risk of cardiovascular events. Full results of FOURIER will
be announced in March 2017, during the Scientific Sessions of  the American College of Cardiology
meeting.

As described in currently approved U.S. prescribing information, PCSK9  inhibitors  have

demonstrated reductions of LDL-C as adjunct to maximally tolerated statin therapy in  patients  with
HeFH and/or ASCVD of up to 64%. When PCSK9  inhibitors were used in patients with
hypercholesterolemia considered to be ‘‘statin intolerant’’, LDL-C levels were  reduced  by  45-56%.
Notwithstanding the LDL-C lowering efficacy of PCSK9  inhibitors, we believe their adoption by
patients, physicians, and payors could be adversely impacted  by their higher cost  and their injectable
route of administration.

Additional Therapies in Development

CETP Inhibitors

A number of larger biopharmaceutical  companies have  tried to develop  a  class of  therapies that
target cholesteryl ester transfer protein, or CETP, which mediates the  transfer  of cholesteryl esters  from
HDL-particles to ApoB-containing particles. CETP inhibitors were initially designed  to  raise levels of
HDL-C and are required by FDA to complete  CVOTs in Phase 3 prior to approval. Pfizer  brought the
first drug in this class, torcetrapib, into clinical development but  terminated development  activities  in
December 2006, due to an increase in all-cause  mortality  and cardiovascular  events in the
ILLUMINATE (Investigation of Lipid Level Management  to  Understand its Impact in Atherosclerotic
Events) study. Two other CETP inhibitors, dalcetrapib from Roche  and  evacetrapib from Lilly,  were
investigated in the dal-OUTCOMES  and ACCELERATE studies,  respectively. The development of
dalcetrapib and evacetrapib were terminated in May 2012, and October 2015, respectively,  due  to  lack
of efficacy in their CVOTs, in spite of a 33% reduction in LDL-C in  the case of evacetrapib. An
additional CETP inhibitor, anacetrapib, from Merck, is  being developed and  is currently being
investigated in the Phase 3 REVEAL (Randomized EValuation of  the  Effects  of  Anacetrapib through
Lipid-modification) study. Anacetrapib  has been shown to significantly raise levels of HDL-C and to
lower LDL-C. This Phase 3 CVOT is  expected to complete and report top-line  results in  the middle of
2017.

PCSK9 Inhibitors

The Medicines Company/Alnylam are developing inclisiran, which is  currently in Phase 2 clinical

studies.  Unlike the PCSK9 antibodies from  Sanofi/Regeneron  and Amgen, inclisiran is  a long-acting
RNA interference therapeutic agent that inhibits the  synthesis of PCSK9. Findings from  clinical studies
suggest that inclisiran may be dosed every 3 or  6 months. Like the PCSK9 antibodies, inclisiran  is an
injectable therapy.

Clinical Experience

To date, bempedoic acid has been studied in over 800  patients across  six patient populations:

healthy volunteers; patients with elevated  LDL-C levels;  patients with  Type 2  diabetes and  elevated
LDL-C levels; patients with elevated  LDL-C  levels  and a  history of ‘‘statin  intolerance’’;  patients with
elevated  LDL-C levels taking low, moderate and high doses of the most  commonly prescribed statins;
and patients with both elevated LDL-C and hypertension. The individual design and  results of each of
the completed Phase 2 clinical studies of  bempedoic acid are summarized below.

11

Overall, bempedoic acid has been well-tolerated and associated with  no dose-limiting  adverse

events, or AEs, in over 800 patients who received bempedoic acid.

Phase 2 Clinical Studies Completed in 2016

1002-035—Phase 2 pharmacokinetics/pharmacodynamics clinical study  in patients treated with  high-dose

statin therapy

On October 13, 2016, we announced top-line results for our  Phase 2  PK/PD (1002-035) clinical

study. The eight-week, U.S.-based, multi-center,  randomized, double-blind, parallel  group study
evaluated 68 patients on stable atorvastatin 80 mg per day. All  patients in the study received
atorvastatin 80 mg for four weeks. Patients were then randomized to receive either bempedoic acid
180 mg, or placebo, for four weeks. The primary objectives of the study  were to assess the  LDL-C
lowering efficacy of bempedoic acid 180 mg versus  placebo  on  a  background of  atorvastatin 80  mg, as
well as multiple-dose plasma PK of atorvastatin 80 mg alone and in  combination  with bempedoic acid.
Secondary objectives included assessment of the effect  of  bempedoic  acid on lipid  and cardiometabolic
biomarkers, including high-sensitivity  C-reactive  protein, or hsCRP;  and  characterization  of  the
tolerability and safety of bempedoic acid.

Patients treated with bempedoic acid 180 mg achieved 22  percent (p=0.0028) LDL-C lowering
from baseline compared to placebo with  all  patients on  a background  of atorvastatin  80 mg. There was
a 13 percent reduction in LDL-C in the bempedoic acid group  and a nine percent increase in LDL-C
in the placebo group when added to background atorvastatin 80 mg. Bempedoic acid also demonstrated
an incremental reduction of 35 percent  (p=0.0020)  in hsCRP. Bempedoic acid added to atorvastatin
80 mg produced no clinically relevant effects on atorvastatin PK, and  appeared  to  be  safe and
well-tolerated, with no serious adverse  events reported.

Phase 1 Clinical Studies Completed in 2016

1002-037—Phase 1 clinical pharmacology study to  assess the safety  and tolerability of bempedoic acid

added to maximally tolerated statin  therapy

On October 13, 2016, we announced top-line results from our Phase 1 PK (1002-037) clinical
study. The open-label study assessed the PK levels in 48 healthy  volunteers  receiving  single doses of the
highest doses of the most commonly  prescribed statins—atorvastatin 80 mg,  rosuvastatin 40 mg,
simvastatin 40 mg and pravastatin 80 mg—when added  to  steady-state bempedoic acid 180 mg. The PK
profiles demonstrated in 1002-037 were consistent with  those seen in  previous studies  conducted  with

13

bempedoic  acid, and did not increase  with the highest doses  of the statins tested in combination  with
bempedoic  acid.

1002-034—Phase 1 bioavailability study to assess  the relative oral  bioavailability of bempedoic  acid

180 mg and ezetimibe 10 mg (BA+EZ)

1002-034 is a Phase 1, randomized, open-label, single-dose  study which  is designed  to  assess the

relative oral bioavailability of bempedoic acid 180 mg and  ezetimibe 10  mg  co-administered as
individual tablets versus as two different fixed dose combination  formulation tablets  in healthy human
subjects. Based on the findings from this  study, we  have selected the  formulation for BA+EZ which we
intend to take forward into development. We expect  to  announce clinical  development and regulatory
plans for BA+EZ in the first half of 2017.

Overall Safety Observations

To date, in completed studies, over 800 patients have been treated with  bempedoic acid for periods

of up to 12 weeks at maximum repeated doses of 240 mg per day.  Bempedoic acid has been safe and
well-tolerated with no dose-limiting side  effects identified to date  in our  ongoing or completed clinical
studies.  No clinical safety trends have  emerged  to  date.

Ongoing Clinical Studies

The clinical development program for bempedoic acid  consists of two major components:  1)  the
global  pivotal Phase 3 LDL-C lowering  program  in high CVD  risk patients with hypercholesterolemia
on optimized background lipid-modifying therapy,  including maximally tolerated statins,  and patients
who are only able to tolerate less than the  lowest approved daily starting dose  of  their  statin  and are
considered ‘‘statin intolerant,’’ and 2)  the CLEAR  Outcomes CVOT in  patients with
hypercholesterolemia and high CVD  risk and who are considered ‘‘statin  intolerant’’.

Global regulatory  submissions for an  LDL-C lowering indication  are expected  by  the first half  of

2019 for a New Drug Application, or NDA, to the FDA and  a  Marketing Authorization  Application, or
MAA,  to the European Medicines Agency, or EMA. The Company expects to submit a NDA for
cardiovascular risk reduction to the FDA  and a  MAA to the  EMA, on the basis  of a successful
completion of the CLEAR Outcomes  CVOT by 2022.

14

Study 1—Global pivotal Phase 3 long-term safety and tolerability study in patients with
hypercholesterolemia on maximally tolerated background lipid-modifying therapy

Study 1 is a 52-week global pivotal Phase 3  randomized, double-blind, placebo-controlled study
evaluating the long-term safety and tolerability of 180 mg of  bempedoic acid versus placebo in patients
with ASCVD and/or HeFH at high CVD risk whose LDL-C is not adequately controlled with current
lipid-modifying therapies. At initiation  the study included 900  patients but was expanded to
approximately 2,000 patients to further  support  our regulatory  submissions for  an LDL-C lowering
indication expected in the first half of 2019.  The study enrolled patients  at approximately 100 sites  in
the U.S.,  Canada and Europe. The primary objective is  to assess safety and tolerability of patients
treated with bempedoic acid for 52 weeks.  Secondary objectives include assessing the  LDL-C lowering
efficacy of bempedoic acid on top of maximally tolerated statin and other lipid altering  therapies  at 12,
24 and 52 weeks versus placebo. Effects on other risk markers,  including non-high-density  lipoprotein,
or non-HDL-C, total cholesterol, apolipoprotein B, or  apoB, and  hsCRP, will also  be  evaluated.  We
initiated Study 1 in January 2016, and  completed patient enrollment ahead of  schedule in January 2017.
We  expect to report top-line results in  the second  quarter of 2018.

Additional safety data will be obtained from  an open-label extension  study which will enroll
approximately 1,300 patients of the approximately  2,000 patients originally enrolled  in Study 1. This
open-label extension study will evaluate  the long-term safety of 180 mg of  bempedoic acid versus
placebo in patients with hypercholesterolemia with ASCVD  and/or HeFH on maximally  tolerated
background lipid-modifying therapies,  including patients on  any  statin  at any dose. This  open-label
extension study will be conducted at  approximately 100 sites included in the parent  study in  the U.S.,
Canada and Europe. The primary objective is  to  assess  the long-term  safety in patients treated with
bempedoic  acid for up to 1.5 years. Secondary objectives include evaluating the 52- and 78-week  effects
of bempedoic acid on lipid and cardiometabolic risk markers, including LDL-C, non-HDL-C, total
cholesterol, apoB and hsCRP.

Study 2—Global pivotal Phase 3 safety  and efficacy study in patients  with hypercholesterolemia not

adequately controlled with current lipid-modifying therapy

Study 2 is a 52-week global pivotal Phase 3  randomized, double-blind, placebo-controlled study

evaluating the safety and efficacy of 180  mg of bempedoic acid versus placebo. This study is expected
to enroll 750 patients with hypercholesterolemia (with ASCVD  and/or HeFH) at  high CVD  risk and
whose LDL-C is not adequately controlled with current  lipid-modifying therapies. The study  will be
conducted at approximately 125 sites  in  the U.S.,  Canada and  Europe. The primary objective is to
assess the 12-week LDL-C lowering efficacy of patients treated with  bempedoic acid versus placebo.
Secondary objectives include evaluating the 24-week LDL-C lowering efficacy, and 52-week  safety and
tolerability of bempedoic acid versus  placebo. Effects on other risk markers, including  non-HDL-C,
total cholesterol, apoB, and hsCRP, will  also  be  evaluated. We initiated Study 2  in December  2016, and
expect to report top-line results by mid-2018.

Study 3—Global pivotal Phase 3 safety  and efficacy study in patients  with hypercholesterolemia on
optimized background lipid-modifying therapy, including patients considered ‘‘statin intolerant’’

Study 3 is a 24-week global pivotal Phase 3  randomized, double-blind, placebo-controlled study

evaluating the safety and efficacy of 180  mg of bempedoic acid versus placebo. This study is expected
to enroll 300 patients with hypercholesterolemia on  optimized background lipid-modifying therapy,
including patients considered ‘‘statin  intolerant.’’ The study will be conducted at approximately 70  sites
in the U.S. and Canada. The primary  objective  is to assess the 12-week LDL-C lowering efficacy of
patients treated with bempedoic acid  versus placebo. Secondary objectives include  evaluating  the
24-week LDL-C lowering efficacy, safety  and  tolerability of bempedoic acid  versus  placebo and effects

15

on other risk markers, including non-HDL-C,  total cholesterol,  apoB and hsCRP. We initiated Study 3
in December 2016, and expect to report top-line results by mid-2018.

Study 4—Global pivotal Phase 3 safety  and efficacy study in patients  with hypercholesterolemia on

optimized background lipid-modifying therapy, including ezetimibe,  and patients considered ‘‘statin
intolerant’’

Study 4 is a 12-week global pivotal Phase 3  randomized, double-blind, placebo-controlled study

evaluating the safety and efficacy of 180  mg of bempedoic acid versus placebo as an  add-on to 10 mg
of ezetimibe. This  study is expected to  enroll 225 patients with hypercholesterolemia on optimized
background lipid-modifying therapy, including ezetimibe, and  patients considered ‘‘statin intolerant.’’
The study will be conducted at approximately  75 sites  in the  U.S.,  Canada and Europe. The primary
objective is to assess the 12-week LDL-C lowering efficacy of patients treated with bempedoic acid
versus placebo when added to ezetimibe. Secondary  objectives include  evaluating safety  and tolerability
of bempedoic acid when added to ezetimibe, and effects on other risk markers,  including non-HDL-C,
total cholesterol, apoB and hsCRP. We initiated Study 4  in December 2016,  and expect to report
top-line  results by mid-2018.

Global Cardiovascular Outcomes Trial—CLEAR Outcomes

CLEAR  Outcomes is an event driven, global, randomized, double-blind, placebo-controlled study

to assess the effects of bempedoic acid  in patients with  hypercholesterolemia who  are at  high risk of
CVD and who are only able to tolerate less than  the lowest  approved starting dose  of a statin and can
be considered ‘‘statin intolerant’’. The  CLEAR  Outcomes  CVOT is  expected  to  enroll approximately
12,600 patients with hypercholesterolemia and high  CVD risk at more  than 600 sites in approximately
30 countries. The study is expected to  enroll over  a 30-month  period with a total estimated study
duration of approximately 4.75 years. The expected average treatment  duration will be 3.5 years with a
minimum treatment duration of approximately 2.25 years. Patients enrolling in  the study will be
required to have a history of, or be at  high-risk for,  CVD with LDL-C levels between 100 mg/dL and
190 mg/dL despite background lipid-lowering  therapy, resulting in an expected average baseline  LDL-C
level  in all patients of approximately  135 mg/dL.  The primary efficacy endpoint of the event-driven
global  study is the effect of bempedoic  acid  versus  placebo on  the risk of major adverse cardiovascular
events (cardiovascular death, non-fatal myocardial  infarction, non-fatal  stroke,  hospitalization for
unstable angina, or coronary revascularization; also referred to as ‘‘five-component  MACE’’).  We
initiated CLEAR Outcomes in December  2016, and the study is intended to support our submissions
for a CV risk reduction indication in the  U.S. and Europe by  2022.

Research and Development Expenses

Research and development expenses for the year ended December 31, 2016, were $57.9 million.

Sales and Marketing

Given our stage of development, we  have not yet established a commercial organization  or
distribution capabilities, nor have we entered into any partnership or co-promotion arrangements with
an established pharmaceutical company.  To develop  the appropriate  commercial  infrastructure to
launch bempedoic acid in the United  States, if approved, as a treatment  for patients  with elevated
LDL-C, we would need to invest significant financial and  managerial resources. We  may engage in
partnering discussions with third parties  from time  to  time.  If we elect to seek approval and launch
commercial sales of bempedoic acid outside  of  the United States or for  broader patient populations in
the United States, including ‘‘statin intolerant’’ patients  who are unable  to reach their LDL-C goal with
a statin therapy, we may either do so  on our own  or by establishing  alliances  with one or  more

16

pharmaceutical company collaborators, depending on,  among other things, the applicable indications,
the related development costs and our available  resources.

Manufacturing and Supply

Bempedoic acid is a small molecule drug  that is synthesized from readily available  raw materials

using conventional chemical processes.  We currently have no  manufacturing  facilities  and limited
personnel with manufacturing experience. We rely on contract manufacturers to produce both drug
substances and drug products required for  our  clinical  studies. All  lots of drug substance and drug
product  used in clinical studies are manufactured under current  good  manufacturing  practices.  We plan
to continue to rely upon contract manufacturers and, potentially, collaboration partners to manufacture
commercial quantities of bempedoic  acid, if approved.

Licenses

In April 2008, we entered into an agreement  with Pfizer  pursuant to which we  acquired a

worldwide, exclusive, fully paid-up license from Pfizer to certain patent rights owned or controlled by
Pfizer relating to bempedoic acid, and we granted Pfizer a worldwide, exclusive, fully paid-up license to
certain patent rights owned or controlled  by us  relating to development programs other than
bempedoic  acid. The license to us covers the development,  manufacture and commercialization of
bempedoic  acid. We may grant sublicenses under the license. Under the  license agreement,  Pfizer is
restricted from making, using, developing or  testing any of the compounds  claimed  under the same
patents that claim or cover the composition  of matter  of  bempedoic  acid. Neither party  is entitled  to
any royalties, milestones or any similar  development or commercialization payments under the  license
agreement, and the licenses granted  are  irrevocable and  may not be terminated for any  cause, including
intentional breaches or breaches caused by  gross negligence.

Intellectual Property

We  strive to protect and enhance the proprietary technologies that  we believe are important  to our

business, including seeking and maintaining patents intended to cover our  products and compositions,
their methods of use and any other inventions  that are important  to  the development of our business.
We  also rely on trade secrets to protect aspects of our  business that are not  amenable to, or that we do
not consider appropriate for, patent protection.

Our success will depend significantly on  our  ability to obtain and maintain patent and other
proprietary protection for commercially  important technology, inventions and know-how related to our
business, defend and enforce our patents, preserve the confidentiality of our  trade secrets and  operate
without infringing the valid and enforceable  patents and proprietary  rights of third parties.  We also rely
on know-how, continuing technological  innovation and  in-licensing opportunities to develop, strengthen
and maintain the proprietary position of bempedoic  acid  and our other development programs.

As of December 31, 2016, our patent estate,  including patents  we  own or license from third

parties, on a worldwide basis, included  approximately  25 issued United States patents and four pending
United States patent applications and  23 issued patents and 15  pending  patent  applications in other
foreign jurisdictions. Of our worldwide patents and pending applications, only a subset  relates to our
small molecule program which includes  our lead product  candidate, bempedoic acid. Bempedoic  acid is
claimed in U.S. Patent No. 7,335,799 that  is scheduled to expire in  December 2025, which includes
711 days of patent term adjustment,  and may be eligible  for a  patent term extension period of up to
five years. U.S. Patent Nos. 9,000,041  and 8,497,301 claim methods of treatment using bempedoic acid.
We  also have a pending U.S. patent application directed to  bempedoic acid. There are  currently  three
issued patents and four pending application in countries outside the United States that relate to
bempedoic  acid.

17

A subset of this portfolio relates to our planned fixed dose combination of bempedoic acid and

ezetimibe and bempedoic acid and one or more statins. We have one pending application outside the
United States claiming methods of treatment using a fixed dose combination of bempedoic  acid and
ezetimibe. We have one pending application outside  the United States claiming methods  of treatment
using a fixed dose combination of bempedoic acid and one  or more statins.

We  hold an exclusive, worldwide, fully  paid-up  license from Pfizer  to  additional patents and patent

applications.

The term of individual patents depends upon  the legal  term  of  the patents in the  countries in
which  they are obtained. In most countries in which we  file, the  patent  term is 20 years from the date
of filing the non-provisional application. In the United States, a patent’s term may be lengthened by
patent term adjustment, which compensates a patentee for administrative delays by the U.S. Patent and
Trademark Office in granting a patent,  or may be shortened  if a patent is  terminally disclaimed over an
earlier-filed patent. In addition, in certain instances, a patent  term can be extended to recapture  a
portion of the term effectively lost as a  result of the  FDA regulatory review  period. However, the
restoration  period cannot be longer than five years and the total patent term  including the  restoration
period must not exceed 14 years following FDA approval. The duration of foreign patents  varies  in
accordance with provisions of applicable local  law,  but typically  is also twenty  years  from the earliest
effective filing date. Our issued U.S. patents  will expire on dates  ranging from 2021  to  2030. However,
the actual protection afforded by a patent  varies  on a claim by claim basis  for each  applicable product,
from country to country and depends upon many factors, including the type  of patent, the scope of its
coverage, the availability of regulatory  related extensions,  the  availability of legal  remedies in  a
particular country and the validity and  enforceability of  the patent.

Furthermore, the patent positions of biotechnology and pharmaceutical  products and processes like

those we intend to develop and commercialize are generally uncertain  and involve complex legal and
factual questions. No consistent policy regarding the breadth of claims  allowed  in such patents  has
emerged to date in the U.S. The patent situation outside the U.S.  is even more  uncertain. Changes  in
either the patent laws or in interpretations of patent laws  in the  U.S.  and other countries  can diminish
our  ability to protect our inventions,  and enforce our intellectual property rights and  more generally,
could affect the value of intellectual  property.  Accordingly, we cannot  predict the breadth  of  claims that
may be allowed or enforced in our patents or in  third-party  patents.

The biotechnology and pharmaceutical  industries are characterized by  extensive  litigation regarding

patents and other intellectual property  rights.  Our ability to  maintain and solidify our proprietary
position for our drugs and technology will depend on  our success  in obtaining effective claims and
enforcing those claims once granted.  We do not know whether any of the patent applications that we
may file or license from third parties  will result  in the issuance of any patents. The issued patents that
we own or may receive in the future, may be challenged, invalidated or circumvented,  and the  rights
granted under any issued patents may  not provide  us with  proprietary protection or competitive
advantages against competitors with similar technology.  Furthermore, our  competitors may be able to
independently develop and commercialize similar  drugs  or duplicate our technology, business model or
strategy without infringing our patents.  Because  of the extensive  time  required for clinical  development
and regulatory review of a drug we may  develop, it is possible that,  before any  of  our  drugs can be
commercialized, any related patent may  expire or remain in force for only a short period  following
commercialization, thereby reducing any advantage  of  any such patent.

As a result of the America Invents Act of 2011, the  United States transitioned to a first-

inventor-to-file system in March 2013,  under which, assuming the other requirements for patentability
are met, the first inventor to file a patent application will be entitled to the patent. This will require us
to minimize the time from invention  to  the  filing of a patent application.

18

We  may rely, in some circumstances, on  trade secrets and unpatented know-how  to  protect our

technology. However, trade secrets can  be  difficult  to  protect. We  seek to  protect our proprietary
technology and processes, in part, by entering into confidentiality agreements with our consultants,
scientific advisors and contractors and  invention  assignment agreements with our employees.  We also
seek to preserve the integrity and confidentiality of our data and trade secrets  by  maintaining  physical
security of our premises and physical  and electronic security of our  information technology systems.
While we have confidence in these individuals, organizations  and systems, agreements or security
measures may be breached and we may  not have adequate  remedies for any  breach.  In addition, our
trade secrets may otherwise become known or be independently  discovered by competitors. To the
extent that our consultants, contractors  or collaborators 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.
For more information, please see ‘‘Risk  Factors—Risks Related to our  Intellectual  Property.’’

Our commercial success will also depend in part on  not  infringing  the proprietary  rights of third

parties. It is uncertain whether the issuance  of any third-party  patent  would require us to alter our
development or commercial strategies, or our drugs or processes, obtain  licenses or  cease certain
activities. Our breach of any license agreements  or failure  to  obtain a license to proprietary  rights that
we may require to develop or commercialize our future  drugs may have a material adverse impact on
us. If third parties prepare and file patent  applications in the U.S. that also claim technology  to  which
we have rights, we may have to participate in interference proceedings in  the U.S.  Patent and
Trademark Office, or USPTO, to determine priority  of invention.

In addition, substantial scientific and commercial research  has been conducted  for many  years  in

the areas in which we have focused our  development efforts, which has resulted in third parties having
a number of issued patents and pending patent applications. Patent  applications  in the U.S. and
elsewhere are published only after eighteen months from the priority date. The publication of
discoveries in the scientific or patent literature  frequently occurs  substantially later  than the date on
which  the underlying discoveries were  made. Therefore,  patent applications relating to drugs similar  to
bempedoic  acid and any future drugs, discoveries or technologies  we might develop may  have already
been filed by others without our knowledge.

Competition

Our industry is highly competitive and subject  to  rapid and significant technological change.  Our

potential competitors include large pharmaceutical and biotechnology companies, specialty
pharmaceutical and generic drug companies, academic institutions, government agencies  and research
institutions. Key competitive factors affecting the commercial success  of  our product candidates  are
likely to be efficacy, safety and tolerability profile,  reliability, convenience  of dosing, price and
reimbursement.

The market for cholesterol regulating  therapies is especially large and  competitive. The product

candidates we are currently developing,  if  approved, will face intense competition,  either as
monotherapies or as combination therapies.

Many of our existing or potential competitors have  substantially greater  financial, technical and

human resources than we do and significantly greater experience  in the discovery and  development of
product  candidates, obtaining FDA and  other regulatory approvals of products and the
commercialization of those products. Mergers and  acquisitions in  the pharmaceutical  and biotechnology
industries may result in even more resources being concentrated among  a small  number of our
competitors. Accordingly, our competitors may  be  more successful than  we may be in obtaining FDA
approval for drugs and achieving widespread market acceptance. Our competitors’ drugs may  be  more
effective, or more effectively marketed  and sold, than any drug we may commercialize and  may render
our  product candidates obsolete or non-competitive before we can recover the expenses of developing

19

and commercializing any of our product candidates. Our  competitors may also obtain FDA or other
regulatory approval for their products  more rapidly than we may obtain approval for  ours.  We
anticipate that we will face intense and  increasing  competition as new drugs  enter the market and
advanced technologies become available. Finally, the  development of new treatment methods for the
diseases  we are targeting could render  our  drugs  non-competitive  or  obsolete. See ‘‘Risk Factors—Risks
Related to our Business and the Clinical  Development  and Commercialization of  Bempedoic
Acid—Our market is subject to intense competition. If we are unable to compete effectively,  our
opportunity to generate revenue from  the sale  of  bempedoic  acid, if approved, will be materially
adversely affected.’’

Regulatory Matters

Government Regulation and Product Approval

Government authorities in the United States  at the federal, state and local level,  and other
countries, extensively regulate, among  other  things, the research,  development, testing,  manufacture,
quality control, approval, labeling, packaging,  storage, record-keeping,  promotion,  advertising,
distribution, marketing, export and import  of  products such as  those we are developing. Our product
candidates, including bempedoic acid, must  be  approved by the FDA through the NDA process before
they may legally be marketed in the United States.

United States Drug Development Process

In the United States, the FDA regulates drugs under the Federal Food, Drug,  and Cosmetic Act,

or FDCA, and implementing regulations. The process of obtaining regulatory  approvals and compliance
with appropriate federal, state, local  and  foreign statutes and  regulations  require the expenditure  of
substantial time and financial resources.  Failure to comply with  the applicable  U.S. requirements at any
time during the product development process, approval process, or after  approval, may subject an
applicant to administrative or judicial  sanctions. These  sanctions could  include the FDA’s  refusal to
approve pending applications, withdrawal of an approval, a clinical hold, warning letters,  product
recalls, product seizures, total or partial suspension of  production or distribution, injunctions, fines,
refusals of government contracts, restitution, disgorgement or civil or criminal penalties. The process
required by the FDA before a drug may be marketed in the  United States generally involves the
following:

• completion of nonclinical laboratory tests, animal  studies and formulation  studies according to

Good Laboratory Practices regulations;

• submission to the FDA of an IND,  which must become  effective  before  human clinical  studies

may begin;

• performance of adequate and well-controlled human clinical studies according  to  Good Clinical
Practices, or GCP, to establish the safety  and  efficacy of the  proposed drug for its  intended use;

• submission to the FDA of an NDA for a new drug;

• satisfactory completion of an FDA  inspection of the manufacturing facility or facilities at which

the drug is produced to assess compliance with  cGMP; and

• FDA review and approval of the NDA.

The testing and approval process requires substantial time, effort and financial resources  and we

cannot be certain that any approvals  for our product candidates will  be  granted  on a  timely  basis, if at
all.

20

Once a pharmaceutical product candidate is identified for development,  it enters the nonclinical,
also referred to as preclinical, testing  stage. Nonclinical  tests include laboratory evaluations of product
chemistry, toxicity, formulation and stability, as well as animal studies.  An IND sponsor must submit
the results of the nonclinical tests, together  with manufacturing  information, analytical data and any
available clinical data or literature, to  the FDA as part of the  IND.  The sponsor must also include a
protocol detailing, among other things, the objectives of the initial clinical study, the parameters to be
used in monitoring safety and the effectiveness criteria to be evaluated  if the initial  clinical study lends
itself to an efficacy evaluation. Some  nonclinical testing  may continue even  after the IND is submitted.
The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA places the
clinical study on a clinical hold within  that  30-day  time period.  In such a case,  the IND sponsor and the
FDA must resolve any outstanding concerns before the  clinical study can begin. Clinical holds also may
be imposed by the FDA at any time before or  during clinical studies  due  to  safety concerns or
non-compliance, and may be imposed on all drug products within a certain class of drugs. The  FDA
also can impose partial clinical holds, for  example prohibiting  the initiation of clinical studies of a
certain duration or for a certain dose.

All clinical studies must be conducted under the supervision of one  or more qualified investigators

in accordance with GCP regulations. These regulations include  the requirement that all research
subjects provide informed consent. Further, an  institutional  review board,  or IRB,  must  review and
approve the plan for any clinical study  before it  commences at any institution.  An IRB considers,
among other things, whether the risks  to  individuals participating in the clinical study are  minimized
and are reasonable in relation to anticipated  benefits. The IRB also approves  the information  regarding
the clinical  study and the consent form  that must be provided to each clinical study  subject or his or
her legal representative and must monitor  the clinical study  until completed.

Each  new clinical protocol and any amendments to the protocol  must be submitted to the IND for

FDA review, and to the IRBs for approval. Protocols detail, among other things, the objectives of the
clinical study, dosing procedures, subject selection and exclusion  criteria, and the  parameters  to  be  used
to monitor subject safety.

Human clinical studies are typically conducted in three sequential phases  that may  overlap or be

combined:

• Phase 1. The product is initially introduced into healthy  human subjects  and tested for  safety,

dosage tolerance, absorption, metabolism, distribution  and excretion. In the case  of  some
products for severe or life- threatening diseases, especially when the  product may  be  too
inherently toxic to ethically administer to healthy  volunteers, the initial  human testing may be
conducted in patients.

• Phase 2. Involves clinical studies in a limited patient population to identify possible adverse

effects and safety risks, to preliminarily  evaluate the  efficacy of the product for specific targeted
diseases  and to determine dosage tolerance and optimal dosage  and schedule.

• Phase 3. Clinical studies are undertaken to further evaluate dosage, clinical efficacy  and safety in
an expanded patient population at geographically dispersed clinical study sites. These  clinical
studies  are intended to establish the overall  risk/benefit ratio  of  the product and provide an
adequate basis for product labeling.

Progress reports detailing the results  of  the clinical studies must  be  submitted at  least annually to

the FDA and safety reports must be  submitted to the FDA and the  investigators  for serious and
unexpected adverse events. Phase 1, Phase  2 and  Phase 3 testing may not be completed successfully
within any specified period, if at all. The FDA or  the sponsor  may  suspend or  terminate a clinical study
at any time on various grounds, including  a finding that  the research subjects or patients are  being
exposed  to an unacceptable health risk. Similarly, an IRB  can suspend or terminate approval of a

21

clinical study at its institution if the clinical study is not being conducted  in accordance with  the IRB’s
requirements or if the drug has been associated  with unexpected serious harm to patients.

Concurrent with clinical studies, companies usually  complete additional animal  studies and must
also develop additional information about the chemistry and physical characteristics of  the product and
finalize a process for manufacturing the  product  in commercial quantities in  accordance  with cGMP
requirements. The manufacturing process must  be  capable of consistently  producing quality batches of
the product candidate and, among other things, the  manufacturer must develop methods  for testing the
identity, strength, quality and purity of the final  product. Additionally,  appropriate  packaging must be
selected  and tested and stability studies must be conducted  to  demonstrate  that  the product candidate
does not undergo unacceptable deterioration over its shelf life.

U.S. Review and Approval Processes

The results of product development, nonclinical studies and clinical studies, along with descriptions

of the manufacturing process, analytical tests conducted on the drug, proposed labeling  and other
relevant information, are submitted to  the FDA as part of an NDA for a new drug,  requesting  approval
to market the product. The submission of  an NDA  is subject  to  the payment  of a substantial user fee; a
waiver of such fee may be obtained under certain  limited  circumstances.  For example,  the agency will
waive the application fee for the first human drug application that  a small  business  or its affiliate
submits for review.

In addition, under the Pediatric Research Equity  Act  of  2003, or PREA, made into permanent law

pursuant to Food and Drug Administration Safety and Innovation  Act (FDASIA), an NDA  or
supplement to an NDA must contain data to assess the safety and effectiveness of the drug for the
claimed indications in all relevant pediatric subpopulations and to support dosing and administration
for each  pediatric subpopulation for  which the product is safe  and effective. The  FDA  may grant
deferrals for submission of data or full  or partial  waivers.

The FDA reviews all NDAs submitted to ensure  that  they are sufficiently complete  for substantive

review before it accepts them for filing.  The FDA may request additional information rather than
accept an NDA for filing. In this event, the NDA  must  be  re-submitted with the additional  information.
The re-submitted application also is subject to review before  the FDA accepts it for  filing. Once  the
submission is accepted for filing, the  FDA begins  an in-depth substantive review. The FDA reviews  an
NDA  to determine, among other things, whether a product is  safe and  effective for its  intended use
and whether its manufacturing is cGMP-compliant  to  assure and preserve the  product’s identity,
strength, quality and purity. Before approving an  NDA, the  FDA will inspect the  facility or  facilities
where  the product is manufactured. The FDA  will  not  approve an  application  unless it determines that
the manufacturing processes and facilities  are in compliance  with cGMP requirements  and adequate to
assure consistent production of the product within  required specifications. The FDA also can  require,
or an NDA applicant may voluntarily  propose, a  Risk Evaluation and Mitigation Strategy,  or REMS, to
ensure the benefits of a drug outweigh its risks. Elements of a REMS may  include ‘‘dear  doctor
letters,’’ a medication guide, and in some  cases restrictions on distribution. These elements are
negotiated as part of the NDA approval, and  in some cases may delay  the  approval date.  Once
adopted, REMS are subject to periodic assessment and modification.  The FDA may  refer the NDA to
an advisory committee for review, evaluation  and  recommendation  as to whether the application should
be approved and under what conditions. An advisory committee is a panel of experts who provide
advice and recommendations when requested  by the  FDA on  matters of importance that come before
the agency. The FDA is not bound by  the  recommendation  of  an advisory committee.

The approval process is lengthy and difficult and the  FDA may refuse to approve  an NDA if the

applicable regulatory criteria are not  satisfied or  may  require  additional clinical data or other data  and
information. Even if such data and information  are submitted, the FDA may ultimately decide  that  the

22

NDA  does not satisfy the criteria for approval. Data  obtained from  clinical studies are not always
conclusive and the FDA may interpret data  differently than we interpret the same  data.  The FDA will
issue a complete response letter if the agency  decides not to approve the NDA in its  present  form. The
complete response letter usually describes all of the specific deficiencies that the  FDA identified in the
NDA.  The deficiencies identified may  be minor,  for example, requiring labeling changes, or major, for
example, requiring additional clinical studies. Additionally, the complete response letter may include
recommended actions that the applicant  might take to place the application in a  condition for  approval.
If a  complete response letter is issued,  the  applicant may  either resubmit  the NDA,  addressing all of
the deficiencies identified in the letter,  or withdraw  the application or request an opportunity for a
hearing.

If a  product receives regulatory approval, the approval may be significantly  limited to specific
patient populations, therapeutic settings,  risk  categories of disease, and dosages  or the indications for
use may otherwise be limited, which could restrict  the commercial  value of  the product. Further, the
FDA may require that certain contraindications, warnings  or  precautions be included in the  product
labeling. In addition, the FDA may require further Phase  3  and  Phase 4 testing to be conducted, which
involves clinical studies designed to further assess a drug’s safety and effectiveness after NDA approval
and may require testing and surveillance programs to monitor the safety  of  approved products that
have been commercialized.

Patent Term Restoration and Marketing Exclusivity

Depending upon the timing, duration and specifics of  FDA approval of the use of  our product
candidates, some of our U.S. patents  may be eligible for  limited patent term extension  under the  Drug
Price Competition and Patent Term Restoration  Act of 1984, commonly referred to as  the Hatch-
Waxman Act. The Hatch-Waxman Act  permits a  patent restoration term of up to five  years  as
compensation for patent term lost during  product development and  the FDA regulatory review  process.
However, patent term restoration cannot extend  the remaining  term of a patent beyond  a total of
14 years from the product’s approval  date. The patent term restoration period is  generally one-half the
time between the effective date of an IND and the submission  date of an NDA plus the  time between
the submission date of an NDA and the  approval of that application. Only one patent applicable to an
approved drug is eligible for the extension and  the application  for the  extension must be submitted
prior to the expiration of the patent.  The U.S. Patent and Trademark Office, in consultation with the
FDA, reviews and approves the application for any patent term extension or restoration. In  the future,
we intend to apply for restorations of patent term for some of our currently owned or licensed patents
to add  patent life beyond their current expiration dates, depending on the expected length of the
clinical studies and other factors involved in the filing of the relevant NDA, however  there can  be  no
assurance that any such extension will  be granted to us.

Market exclusivity provisions under the FDCA can also delay the submission or the approval  of

certain applications. The FDCA provides a  five-year period of non-patent marketing exclusivity  within
the United States to the first applicant to gain  approval of  an NDA for a new chemical entity. A drug
is a new chemical entity if the FDA has  not  previously  approved any  other  new drug containing  the
same active moiety, which is the molecule or  ion responsible for the action of the  drug  substance.
During  the exclusivity period, the FDA  may not accept for  review an abbreviated new drug  application,
or ANDA, or a 505(b)(2) NDA submitted by another  company for another version  of  such drug where
the applicant does not own or have a legal right of reference to all  the data required for  approval.
However, an application may be submitted after four years  if it contains a certification of  patent
invalidity or non-infringement. The FDCA  also provides  three years of  marketing  exclusivity for  an
NDA,  505(b)(2) NDA or supplement  to  an existing NDA if new clinical  investigations, other than
bioavailability studies, that were conducted or sponsored  by the applicant are deemed  by  the FDA to
be essential to the  approval of the application, for example new indications, dosages or strengths of an

23

existing drug. This three-year exclusivity  covers only the  conditions of use associated with the new
clinical investigations and does not prohibit the  FDA  from  approving ANDAs for  drugs containing the
original active agent. Five-year and three-year exclusivity will  not  delay the submission  or approval of a
full NDA. However, an applicant submitting a full NDA would be required to conduct  or obtain a  right
of reference to all of the nonclinical  studies and adequate and well- controlled clinical  studies necessary
to demonstrate safety and effectiveness.

Pediatric exclusivity is another type of  exclusivity in the  United States.  Pediatric  exclusivity, if
granted, provides an additional six months to an existing  exclusivity or statutory delay in approval
resulting from a patent certification.  This  six-month exclusivity, which  runs from  the end of other
exclusivity protection or patent delay,  may be granted  based on the voluntary completion of  a pediatric
clinical study in accordance with a FDA-issued ‘‘Written  Request’’  for such a clinical study.

Certain foreign countries permit extension of  patent  term for a newly  approved drug and/or grant

a period of data exclusivity and/or market exclusivity. For example, depending upon  the timing and
duration of the marketing authorization process  in certain  European  countries, a newly approved  drug
may be eligible for a supplementary protection certification, or SPC, which can extend the  basic  patent
right for the drug for a period up to  five years.

Post-Approval Requirements

Any drugs for which we receive FDA approval are subject to continuing regulation by the  FDA,

including, among other things, record-keeping requirements,  reporting  of  adverse experiences with the
product,  providing the FDA with updated safety  and efficacy information, product  sampling and
distribution requirements, complying  with certain electronic records  and  signature requirements  and
complying with FDA promotion and advertising  requirements.  The FDA strictly regulates labeling,
advertising, promotion and other types  of  information  on products that  are placed on the  market.
Drugs may be promoted only for the approved indications and in  accordance with the  provisions of the
approved label. Further, manufacturers  of  drugs must continue to comply with  cGMP requirements,
which  are extensive and require considerable  time, resources and ongoing  investment to ensure
compliance. In addition, changes to the  manufacturing process generally require prior FDA approval
before being implemented and other  types of changes  to  the  approved product, such as  adding new
indications and additional labeling claims, are also subject to further  FDA review and approval.

Drug manufacturers and other entities involved in the  manufacturing and distribution of approved

drugs are required to register their establishments with the  FDA and certain state  agencies, and are
subject to periodic unannounced inspections by the  FDA and certain state  agencies for compliance with
cGMP and other laws. The cGMP requirements apply to all stages of  the manufacturing  process,
including the production, processing, sterilization, packaging, labeling, storage and shipment of the
drug. Manufacturers must establish validated  systems to ensure that products meet specifications  and
regulatory standards, and test each product batch  or lot prior to its release. We  rely, and expect to
continue to rely, on third parties for  the production  of clinical quantities of  our  product candidates.
Future FDA and state inspections may  identify compliance  issues at the facilities of our contract
manufacturers that may disrupt production or  distribution or  may require substantial resources to
correct.

The FDA may withdraw a product approval if compliance with regulatory  requirements is not

maintained or if problems occur after the  product reaches the market. Later discovery of previously
unknown problems with a product may result in restrictions on the  product or even complete
withdrawal of the product from the market. Further, the  failure to maintain  compliance with regulatory
requirements may result in administrative  or judicial  actions, such as fines, warning  letters, holds on
clinical studies, product recalls or seizures, product detention or refusal to permit the import or export

24

of products, refusal to approve pending  applications or supplements, restrictions on  marketing or
manufacturing, injunctions or civil or  criminal  penalties.

From time to time, legislation is drafted, introduced and passed in  Congress that could significantly

change the statutory provisions governing the  approval, manufacturing  and  marketing of  products
regulated by the FDA. In addition to new legislation, the FDA regulations and policies are often
revised or reinterpreted by the agency  in ways  that may significantly  affect our business and  our
product  candidates. It is impossible to predict whether further legislative or FDA regulation or  policy
changes will be enacted or implemented and  what the  impact of such  changes, if any,  may be.

Foreign Regulation

In addition to regulations in the United States, we  will  be subject  to  a  variety  of foreign

regulations governing clinical studies and commercial sales and distribution of our product  candidates
to the extent we choose to sell any products  outside of the United States.  Whether or  not  we obtain
FDA approval for a product, we must obtain approval of a product by the  comparable  regulatory
authorities of foreign countries before we can  commence clinical studies  or marketing of the product in
those countries. The approval process  varies from country to  country  and  the time  may be longer or
shorter than that required for FDA approval. The  requirements governing the conduct of clinical
studies,  product licensing, pricing and reimbursement vary greatly from country  to  country.  As in  the
United States, post-approval regulatory  requirements,  such as those  regarding product  manufacture,
marketing, or distribution would apply  to  any  product that is approved  outside the  United States.

Employees

As of December 31, 2016, we had 44 full-time  employees. Two of our  employees have Ph.D.
degrees and three have M.D. degrees.  28 of our employees are engaged in  research  and development
activities. None of  our employees are  represented by labor unions or covered by collective bargaining
agreements. We consider our relationship  with our employees to be good.

Facilities

Our corporate headquarters are located in  Ann Arbor, Michigan where we lease  and occupy
approximately 7,900 square feet of office  space. We lease and  occupy an  additional 5,500  square  feet of
office space in Ann Arbor, Michigan to support our  clinical  development operations. We  believe our
current facilities will be sufficient to meet our needs until expiration.

Legal Proceedings

On January 12, 2016, a purported stockholder  of the Company filed  a putative class action lawsuit
in the United States District Court for the Eastern District of Michigan, against us and  Tim Mayleben,
captioned Kevin L. Dougherty v. Esperion Therapeutics,  Inc., et  al. (No. 16-cv-10089). The lawsuit alleges
that we and Mr. Mayleben violated Sections 10(b) and  20(a) of the Securities Exchange  Act of 1934
and SEC Rule 10b-5 by allegedly failing  to disclose in an August 17, 2015,  public statement that the
FDA would require a cardiovascular outcomes  trial before approving our lead product candidate. The
lawsuit seeks, among other things, compensatory  damages  in connection with an  allegedly inflated stock
price between August 18, 2015, and September 28, 2015, as  well as attorneys’  fees  and costs. On
May 20, 2016, an amended complaint  was filed in the lawsuit  and on July 5, 2016, we filed a motion to
dismiss the amended complaint. On December 27, 2016,  the court granted  our motion to dismiss with
prejudice and entered judgment in our  favor. On January  24,  2017, the plaintiffs in this lawsuit filed a
motion to alter or amend the judgment.

On December 15, 2016, a purported stockholder of the  Company filed a  derivative lawsuit in  the
Court of Chancery of the State of Delaware  against Tim Mayleben,  Roger Newton, Mary  McGowan,

25

Nicole Vitullo, Dov Goldstein, Daniel  Janney, Antonio  Gotto Jr., Mark McGovern,  Gilbert Omenn,
Scott  Braunstein, and Patrick Enright.  The Company is  named  as a  nominal defendant.  The  lawsuit
alleges that the defendants breached their fiduciary duties to the Company  when they made or
approved improper statements on August 17, 2015, regarding  our lead product candidate’s  path to  FDA
approval, and failed to ensure that reliable  systems of internal controls were  in place  at the Company.
The lawsuit seeks, among other things,  any  damages sustained by the Company as a result of the
defendants’ alleged breaches of fiduciary duties, including damages related to the above-referenced
securities class action, an order directing the Company  to  take  all necessary actions to reform  and
improve its corporate governance and internal procedures, restitution from the  defendants, and
attorneys’ fees and costs. In light of,  among other  things, the early stage of the  litigation, we are unable
to predict the outcome of this matter  and  are unable  to  make a meaningful  estimate of the  amount or
range of loss, if any, that could result  from an unfavorable  outcome.

In the future, we may become party to  legal matters and claims arising  in the ordinary course of

business, the resolution of which we  do not anticipate would have  a  material adverse impact on our
financial position, results of operations  or cash flows.

Item 1A. Risk Factors

Except  for the historical information contained herein or incorporated  by  reference, this report and the

information incorporated by reference contains forward-looking statements that  involve risks and
uncertainties. These statements include projections about  our accounting and finances, plans and objectives
for the future, future operating and economic performance and other statements regarding future
performance. These statements are not  guarantees  of  future  performance  or events. Our actual  results  could
differ materially from those discussed in  this report. Factors that could cause or  contribute  to these
differences include, but are not limited  to, those discussed in the following  section, as well  as those
discussed in Part II, Item 7 entitled ‘‘Management’s Discussion  and  Analysis  of  Financial  Condition and
Results of Operations’’ and elsewhere throughout this  report and  in any documents incorporated in this
report by reference.

You should consider carefully the following risk factors, together with all of  the  other information
included or incorporated in this report. If  any of the following risks,  either alone or taken  together,  or other
risks not presently known to us or that  we currently believe  to not be significant, develop into actual events,
then our business, financial condition,  results of operations or prospects  could be materially adversely
affected. If that happens, the market price of our common stock could decline,  and stockholders  may lose
all or part of their investment.

Risks Related to our Business and the Clinical Development and Commercialization of Bempedoic Acid

We depend almost entirely on the success of  one product candidate, bempedoic acid, which only recently
commenced Phase 3 clinical development. We cannot be certain that we will be able to obtain  regulatory
approval for, or successfully commercialize,  bempedoic acid.

Bempedoic acid and BA + EZ, the fixed dose  combination of bempedoic acid and ezetimibe, are

our  only product candidates in clinical development,  and  our business depends  almost entirely on
bempedoic  acid’s successful clinical development, regulatory  approvals and commercialization. We
currently have no drug products for sale  and may  never be  able to develop  marketable drug products.
Bempedoic acid, for which we recently launched our global  pivotal  Phase 3  clinical program in  January
2016, will require substantial additional clinical  development,  testing, and regulatory approvals before
we are permitted to commence its commercialization. The clinical studies of our product  candidates
are, and the manufacturing and marketing of  our product candidates will  be, subject to extensive and
rigorous review and regulation by numerous government authorities in the U.S. and in other countries
where  we intend to test and, if approved,  market  any product candidate. Before obtaining regulatory
approvals for the commercial sale of  any  product candidate, we must demonstrate  through preclinical
testing and clinical studies that the product candidate is  safe and  effective  for use in each  target
indication. This process can take many years and require the expenditure of substantial  resources
beyond the proceeds we have raised, and may include  post-marketing studies and surveillance, including
a Risk Evaluation and Mitigation Strategy, or REMS program.  Of  the large number of drugs in
development in the U.S., only a small  percentage successfully  complete the approval process at the
FDA, EMA or any other foreign regulatory  agency, and are commercialized. Accordingly, even if we
are able to obtain the requisite financing to continue  to  fund our development  and clinical programs,
we cannot assure you that bempedoic  acid or any other of our product candidates will  be  successfully
developed or commercialized.

We  are not permitted to market bempedoic acid  in the U.S. or Europe  until we  receive approval

of a NDA from the FDA, a MAA from  the EMA, or  in any other foreign countries until  we receive
the requisite approval from such countries. As a condition to  submitting an NDA to the FDA  or an
MAA  to EMA for bempedoic acid to  treat patients with  elevated LDL-C, we have currently completed
eight Phase 2 clinical studies and expect to complete the  global pivotal Phase 3 LDL-C lowering
efficacy and safety studies, and to potentially complete, the CLEAR Outcomes CVOT.

27

Additionally, while we currently intend to submit our NDA  for  bempedoic acid for an LDL-C
lowering indication in patients with hypercholesterolemia,  the FDA  has indicated its  position  regarding
an LDL-C lowering indication could be impacted by potential  future changes in their view of  LDL-C
lowering as a surrogate endpoint or the possibility of a shift in  the future  standard-of-care  for ‘‘statin
intolerant’’ patients with elevated LDL-C levels. In  the event  that FDA determines  LDL-C  lowering is
no longer a surrogate endpoint for initial approval  of bempedoic  acid in the  future, we would plan to
submit our  NDA with a proposed indication of CV risk reduction in ‘‘statin intolerant’’  patients  on the
basis of a completed and successful CLEAR Outcomes CVOT,  which would include the results of the
global  pivotal Phase 3 LDL-C lowering  efficacy and safety studies, by 2022. Obtaining approval of an
NDA  is a complex, lengthy, expensive  and uncertain process, and the  FDA may delay, limit or deny
approval of bempedoic acid for many  reasons, including, among  others:

• the FDA, EMA or any other regulatory authorities may change their approval  policies  or adopt
new regulations, including with respect to whether LDL-C lowering is a surrogate endpoint for
initial approval of bempedoic acid;

• we may not be able to demonstrate that bempedoic acid is  safe and effective in treating patients

with elevated LDL-C to the satisfaction of the  FDA, EMA or  any  other regulatory agency;

• the results of our clinical studies may  not  meet  the level of statistical or clinical significance

required by the FDA or EMA for marketing  approval;

• the magnitude of the treatment effect must also be clinically meaningful  along with  the drug’s

safety for a favorable benefit/risk assessment by the  FDA, EMA or any other  regulatory agency;

• the FDA, EMA or any other regulatory agency  may disagree with  the number,  design, size,

duration, exposure of patients, or conduct or implementation of our  clinical studies;

• the FDA, EMA or any other regulatory agency  may require that  we  conduct additional clinical

studies;

• the FDA, EMA or any other regulatory agency  may not approve the formulation, specifications

or labeling of bempedoic acid;

• the clinical research organizations, or CROs, that we retain to conduct our clinical studies  may

take  actions outside of our control that materially adversely impact  our clinical  studies;

• the FDA, EMA or any other regulatory agency  may find  the data from  preclinical studies  and
clinical studies insufficient to demonstrate that bempedoic  acid’s clinical and other benefits
outweigh its safety risks;

• the FDA, EMA or any other regulatory agency  may disagree with  our interpretation of data

from our preclinical studies and clinical studies;

• the FDA, EMA or any other regulatory agency  may not accept data  generated at  our  clinical

study sites;

• if  our NDA, if and when submitted, is reviewed by an advisory  committee, the  FDA  may have

difficulties scheduling an advisory committee meeting in  a timely  manner  or  the advisory
committee may recommend against approval of  our application or may recommend  that  the
FDA require, as a  condition of approval, additional preclinical studies  or  clinical  studies,
limitations in approved labeling or distribution and use  restrictions;

• the FDA, EMA or any other regulatory agency  may require the development of  a REMS as a

condition of approval or post-approval; or

• the FDA, EMA or any other regulatory agency  may not approve the manufacturing  processes or

facilities of third-party manufacturers with  which we contract.

28

Any of these factors, many of which are beyond our  control, could jeopardize our ability to obtain

regulatory approval for and successfully  market  bempedoic  acid. Moreover,  because our business is
almost entirely dependent upon this one  product candidate, any  setback in  our  pursuit of its regulatory
approval would have a material adverse effect on  our  business and prospects.

The development and approvals required  for the  approval  of  BA + EZ,  which is in development

for the same indications as bempedoic acid  as monotherapy, are  substantially  identical  to  those for
bempedoic  acid as monotherapy, and  the risks relating  to  the clinical development and approval  of
bempedoic  acid monotherapy apply equally  to  BA +  EZ. The  FDA  only recently  accepted our
submission of an IND application for BA + EZ in the second quarter of 2016 and we  recently
completed a bioavailability study. A formulation of BA  + EZ has  been selected for development and
commercialization. We expect to announce  clinical development and regulatory  plans for BA  + EZ  in
the first half of 2017. Any failure in our development of bempedoic acid monotherapy would materially
and adversely affect our ability to develop, seek approval  for and commercialize the BA  +  EZ
combination therapy for the targeted indications. In addition,  even  if bempedoic acid monotherapy
succeeds in its clinical development and is approved  for  one or more targeted indications, there can be
no assurance that the BA + EZ combination therapy would be developed successfully and  approved
for the same indications or at all.

Failures or delays in the completion of our global pivotal Phase 3  efficacy and safety  studies or our CLEAR
Outcomes CVOT of bempedoic acid could result in increased  costs to us  and could delay, prevent  or limit our
ability to generate revenue and continue  our business.

In January 2016, we commenced our global pivotal Phase 3 long-term safety study (Study 1). We
do not know whether our ongoing clinical  studies will be completed on  schedule, if at all. We initiated
our  three remaining global pivotal Phase 3  LDL-C  lowering  efficacy  studies and the CLEAR Outcomes
CVOT in December 2016. We do not know whether these studies will be completed  on schedule.
Successful completion of such clinical  studies and,  if  required by  the FDA due to a change  in
regulatory policy, our CLEAR Outcomes CVOT, are likely  prerequisites to submitting an initial  NDA
to the FDA, MAA to the EMA or a  similar application to any other foreign regulatory authorities from
whom we seek to obtain approval and, consequently,  the ultimate approval and commercialization of
bempedoic  acid. The commencement and completion of  clinical  studies can be delayed  or prevented for
a number of reasons, including, among  others:

• the FDA, EMA or any other regulatory authority may not agree to the study  design or overall

program;

• the FDA, EMA or any other regulatory authority may place  a  clinical study on  hold;

• delays in reaching or failing to reach agreement on acceptable  terms with prospective CROs and
study sites, the terms of which can be subject to extensive negotiation and may vary significantly
among different CROs and study sites;

• inadequate quantity or quality of a product candidate or other materials necessary to conduct

clinical studies;

• difficulties or delays obtaining institutional review  board, or IRB, approval  to  conduct a  clinical

study at a prospective site or sites;

• challenges in recruiting and enrolling patients to participate in clinical studies or in our CLEAR

Outcomes CVOT,  including the size  and  nature of the  patient population,  the proximity of
patients to clinical sites, eligibility criteria for the clinical study, the nature  of  the clinical  study
protocol, the availability of approved  effective treatments  for  the relevant disease and
competition from other clinical study programs, including PCSK9  inhibitors,  for similar
indications;

29

• severe or unexpected drug-related side effects  experienced by patients in a clinical study,

including instances of muscle pain or weakness or  other  side effects previously identified in  our
completed clinical studies;

• reports from preclinical or clinical testing of other  cardiometabolic therapies that raise safety  or

efficacy concerns; and

• difficulties retaining patients who have enrolled in  a clinical  study  but may be prone  to  withdraw

due to rigors of the study, lack of efficacy, side effects, personal issues  or loss  of interest.

Clinical studies may also be delayed or terminated  as a result  of  ambiguous or negative interim
results. In addition, a clinical study may be suspended  or terminated by us, the FDA, the  EMA, the
IRBs at the sites where the IRBs are  overseeing  a clinical  study,  a  data safety monitoring  board, or
DSMB, overseeing the clinical study at  issue or  any  other  regulatory authorities due to a number of
factors, including, among others:

• failure to conduct the clinical study in accordance  with regulatory requirements or our clinical

protocols;

• inspection of the clinical study operations or  study sites by  the FDA, EMA or  any other
regulatory authorities that reveals deficiencies or  violations that  require us to undertake
corrective action, including the imposition of a clinical  hold;

• unforeseen safety issues;

• changes in government regulations or  administrative actions;

• problems with clinical supply materials; and

• lack of adequate funding to continue the clinical study.

Positive results from completed Phase 1  and Phase 2  clinical studies of bempedoic  acid are not  necessarily
predictive of the results of our ongoing  global pivotal Phase 3 program and CVOT of bempedoic  acid, nor do
they guarantee approval of bempedoic acid by the FDA, EMA or any  other regulatory agency. If we  cannot
replicate the positive results from our completed Phase  1 and Phase 2  clinical  studies of bempedoic acid  in
our ongoing clinical studies and CVOT, we  may  be  unable  to successfully develop, obtain regulatory approval
for  and commercialize bempedoic acid.

There is  a high failure rate for drugs proceeding  through clinical studies.  Even if we  are able  to

complete our ongoing global pivotal Phase 3 LDL-C studies, CVOT and  any potential additional
Phase 3 clinical studies of bempedoic acid according  to  our current development timeline, the  positive
results from our completed Phase 1 and Phase 2 clinical studies of  bempedoic acid, including  those of
our  Phase 2 PK/PD (1002-035) study completed  in October 2016,  may not be replicated in  our  ongoing
global  pivotal Phase 3 and CVOT or  planned Phase 3  clinical study results, nor do they guarantee
approval of bempedoic acid by the FDA,  EMA or  any  other regulatory authorities in  a timely manner
or at all. Many companies in the pharmaceutical and  biotechnology industries have  suffered significant
setbacks in late-stage clinical studies after achieving positive results in early stage development,  and we
cannot be certain that we will not face  similar  setbacks. These setbacks have been  caused by, among
other things, preclinical findings made while  clinical studies were underway or safety  or efficacy
observations made in clinical studies, including  previously unreported adverse events. In addition,
regulatory delays or rejections may be encountered as a  result of  many  factors, including changes in
regulatory policy during the period of product  development.

Moreover, preclinical and clinical data are often  susceptible  to  varying interpretations and  analyses,

and many companies that believed their product candidates performed satisfactorily in preclinical
studies and clinical studies nonetheless  failed to obtain FDA and/or EMA approval. If we fail to obtain

30

positive results in our ongoing global  pivotal Phase  3, CVOT  and  planned Phase  3 clinical studies of
bempedoic  acid, the development timeline and regulatory approval and commercialization prospects for
our  leading product candidate, and, correspondingly, our business  and financial prospects, would  be
materially adversely affected.

We will need substantial additional capital  in the  future. If additional capital is not  available,  we will have  to
delay, reduce or cease operations.

We  reported top-line results from our Phase 2 (1002-008) clinical study in October 2014, our
Phase 2 (1002-009) clinical study in March  2015, our Phase 2 (1002-014) exploratory clinical  safety
study in July 2015, and our Phase 2 PK/PD (1002-035)  clinical  study and Phase  1 PK (1002-037)  study
in October 2016. We held our End-of-Phase 2 meeting with  the FDA in August 2015. In  January 2016,
we commenced our global pivotal Phase 3  long-term safety  study (Study  1). We engaged  in active
dialogue in 2016 with the FDA and EMA to discuss our global  pivotal  Phase 3  clinical program for
bempedoic  acid in the ‘‘statin intolerant’’ patient population and, based on that dialogue, announced
our  clinical development and regulatory  plans for bempedoic acid in  June 2016. We initiated our  global
pivotal Phase 3 LDL-C lowering efficacy studies and our  CLEAR Outcomes CVOT in December 2016.

In the event that FDA determines LDL-C lowering is no longer a surrogate endpoint for initial
approval of bempedoic acid in the future, we  would plan  to submit our NDA for  CV risk  reduction
indication on the basis of a completed and successful CVOT, which would include the results of the
Phase 3 LDL-C lowering efficacy studies, by 2022.  We expect  that these  clinical studies, plus any
additional clinical studies that we undertake for the clinical  development  of BA + EZ, will consume
substantial additional financial resources.  We  expect that  our existing cash and cash  equivalents only
will be sufficient to fund our operations into early 2019. We will need to raise additional capital to
continue to fund the further development and commercialization of bempedoic  acid and  our
operations. Our future capital requirements may  be  substantial  and will  depend on many factors
including:

• the scope, size, rate of progress, results  and  costs of completing our CLEAR Outcomes CVOT

of bempedoic acid;

• the scope, size, rate of progress, results  and  costs of completing our global  pivotal Phase 3

LDL-C lowering program of bempedoic acid, which currently  includes  multiple global  pivotal
Phase 3 clinical efficacy and safety studies;

• the scope, size, rate of progress, results  and  costs of clinical development  of BA + EZ for the

same indications as bempedoic acid monotherapy;

• the cost, timing and outcome of our efforts  to  obtain marketing approval  for bempedoic acid,
including to fund the preparation and  filing of an NDA with the  FDA and  a MAA with the
EMA for bempedoic acid and to satisfy  related FDA and EMA requirements;

• the number and characteristics of any additional product  candidates we develop or acquire;

• the costs associated with commercializing bempedoic acid  or any future  product candidates if  we
receive marketing approval, including the cost and timing of developing sales and  marketing
capabilities or entering into strategic collaborations to market and sell bempedoic  acid  or any
future product candidates;

• the cost of manufacturing bempedoic acid  or any future  product candidates and  any products we

successfully commercialize; and

• the costs associated with general corporate activities, such as  the cost of filing, prosecuting and

enforcing patent claims.

31

Changing circumstances may cause us to consume capital significantly faster than we currently
anticipate. Because the outcome of any  clinical study is highly uncertain, we  cannot reasonably estimate
the actual amounts necessary to successfully complete the development, regulatory  approval and
commercialization of bempedoic acid and any future product  candidates. Additional financing  may not
be available when we need it or may  not  be  available on terms  that are favorable  to  us.  In  addition, we
may seek additional capital due to favorable market conditions  or strategic considerations, even if we
believe we have sufficient funds for our  current  or future  operating plans.  If adequate  funds  are
unavailable to us on a timely basis, or at  all,  we may not be able to continue the  development of
bempedoic  acid or any future product candidate,  or to commercialize  bempedoic acid or  any future
product  candidate, if approved, unless we find a  partner.

We are an emerging pharmaceutical company  and  have not generated any revenue from product sales. We
have incurred significant operating losses  since our  inception, and anticipate that we will incur continued
losses for the foreseeable future.

We  have a limited operating history on which to base your investment  decision.  Pharmaceutical

product  development is a highly speculative undertaking and involves a substantial degree of  risk. We
were incorporated in January 2008. Our operations to date have  been limited primarily to organizing
and staffing our company and conducting  research and development activities for bempedoic acid.  We
have never generated any revenue from  product sales. We have not obtained regulatory approvals for
any of our product candidates. As such,  we are subject  to  all the  risks incident  to  the development,
regulatory approval and commercialization of new pharmaceutical products and we may encounter
unforeseen expenses, difficulties, complications,  delays and  other unknown factors.

Since our inception, we have focused  substantially  all of our efforts and  financial resources on
developing  bempedoic acid, which commenced Phase  3 clinical  development  in January 2016.  We have
funded our operations to date primarily  through proceeds  from  sales of  preferred  stock,  public
offerings of common stock, convertible promissory notes  and warrants  and  the incurrence of
indebtedness, and we have incurred losses in  each year since  our inception. Our  net losses were
$75.0 million, $49.8 million and $36.4  million  for the  years ended December 31,  2016, 2015 and 2014,
respectively. As of December 31, 2016, we had  an accumulated deficit of  $229.2 million. Substantially
all of our operating losses resulted from costs incurred in  connection  with our development program
and from general and administrative  costs associated with our  operations. We expect  to  incur  increasing
levels of operating losses over the next  several  years  and for the foreseeable future. Our prior losses,
combined with expected future losses, have had and will continue to have an adverse effect  on our
stockholders’ equity and working capital. We expect our research  and  development  expenses to
significantly increase in connection with our additional clinical studies  of bempedoic  acid,  particularly
our  Phase 3 program and CLEAR Outcomes  CVOT, as well  as any clinical studies that we  undertake
to develop BA + EZ, and development  of  any  other  product candidates we may choose to pursue. In
addition, if we obtain marketing approval for bempedoic  acid, we will also incur significant sales,
marketing and outsourced manufacturing expenses. As a public company,  we have incurred and will
continue to incur additional costs associated with operating as a public  company, particularly now that
we are no longer an ‘‘emerging growth  company.’’ As a result, we expect  to  continue to incur
significant and increasing operating losses for the  foreseeable future.  Because of the numerous risks
and uncertainties associated with developing  pharmaceutical products, we are unable to predict the
extent of any future losses or when we will become profitable, if at  all. Even if we do become
profitable, we may not be able to sustain or  increase our profitability on a quarterly or  annual basis.

32

Changes in regulatory requirements, FDA  or EMA  guidance or unanticipated events during our global pivotal
Phase 3 clinical studies or our CVOT of  bempedoic acid may occur, which may result in  changes to  clinical
study protocols or additional clinical study requirements,  which could  result  in increased costs to us  and  could
delay our development timeline.

Changes in regulatory requirements,  FDA or EMA guidance  or  unanticipated events during our

clinical studies may force us to amend  clinical study protocols  or the FDA or EMA  may impose
additional clinical study requirements.  Significant  amendments to our clinical study protocols may
require resubmission to the FDA and/or IRBs for review and approval, which  may adversely impact the
cost, timing and/or successful completion of these studies. If  we experience substantial delays
completing—or if we terminate—any of our global  pivotal Phase 3 clinical  studies or our CVOT, or if
we are required to conduct additional  clinical studies, the commercial prospects  for bempedoic acid
may be harmed and our ability to generate  product revenue will  be  delayed.

Even though we completed enrollment of Study 1  ahead of schedule,  we may not be able to
identify and enroll the requisite number of  patients in the remaining studies in  our  global pivotal
Phase 3 LDL-C lowering program, our CLEAR  Outcomes CVOT or any study that we  undertake  to
support the development of BA+EZ. Even when we are successful  in enrolling patients, we may not
ultimately be able to demonstrate sufficient clinical benefits from  bempedoic acid and  our  failure to do
so may delay or hinder our ability to obtain FDA or EMA approval for bempedoic  acid. While we
currently plan to submit an NDA for bempedoic acid for an  LDL-C lowering  indication in patients with
hypercholesterolemia after initiating our  CLEAR Outcomes  CVOT, the FDA has  indicated its position
regarding an LDL-C lowering indication could be impacted  by potential future changes in their  view of
LDL-C lowering as a surrogate endpoint or the possibility of a shift  in the future  standard-of-care  for
‘‘statin intolerant’’  patients with elevated LDL-C levels. Conducting our  CLEAR Outcomes CVOT will
be costly and time-consuming, and any  requirement to complete the CVOT prior to approval of
bempedoic  acid would adversely affect  our development timeline and financial  condition.

Even if we receive marketing approval for  bempedoic  acid, we may still face  future development  and  regulatory
difficulties.

Even if we receive marketing approval for bempedoic acid, regulatory authorities may still impose

significant restrictions on bempedoic acid’s indicated  uses or marketing or impose ongoing
requirements for potentially costly post-approval studies,  such  as a  CVOT.  Bempedoic acid will also be
subject to ongoing FDA requirements governing the packaging, storage, labeling, advertising and
promotion of the product, recordkeeping and submission  of  safety updates and other post-marketing
information. The FDA has significant  post-marketing  authority, including, for  example, the authority to
require labeling changes based on new safety information and to require post-marketing studies or
clinical studies to evaluate serious safety risks related  to  the use  of a  drug product. The FDA also has
the authority to require, as part of an  NDA or  post-approval,  the  submission  of a REMS. Any REMS
required by the FDA may lead to increased costs to assure  compliance with post-approval regulatory
requirements and potential requirements or  restrictions  on  the sale  of  approved products, all of which
could lead to lower sales volume and revenue.  The EMA and other foreign regulatory authorities may
impose similar requirements on bempedoic  acid  as those described above with respect to the FDA.

Manufacturers of drug products and their  facilities  are subject to continual  review and  periodic

inspections by the FDA and other regulatory authorities for  compliance with  current Good
Manufacturing Practices and other regulations. If  we or  a regulatory agency discover problems with
bempedoic  acid, such as adverse events  of unanticipated severity or frequency, or problems with  the
facility where bempedoic acid is manufactured, a regulatory agency may impose  restrictions on
bempedoic  acid, the manufacturer or us,  including requiring  withdrawal of bempedoic acid from the
market or suspension of manufacturing.  If  we, bempedoic acid or  the manufacturing  facilities  for

33

bempedoic  acid fail to comply with applicable regulatory requirements, a regulatory agency  may, among
other things:

• issue warning letters or untitled letters;

• seek an injunction or impose civil or criminal penalties or monetary fines;

• suspend or withdraw marketing approval;

• suspend any ongoing clinical studies;

• refuse to approve pending applications  or supplements  to applications submitted  by  us;

• suspend or impose restrictions on  operations, including costly  new  manufacturing requirements;

or

• seize or detain products, refuse to permit the import or  export of products, or  request  that  we

initiate a product recall.

Even if we receive marketing approval for  bempedoic  acid in the U.S., we may never receive regulatory
approval to market bempedoic acid outside  of the  U.S., and vice versa.

In order to market any product outside of the U.S., we must establish  and comply with the
numerous and varying efficacy, safety and other regulatory requirements of the countries  in which we
intend to market our product. Approval procedures vary among countries  and can involve additional
product  candidate testing and additional administrative review  periods. The time  required to obtain
approvals in other countries might differ from that  required to obtain FDA approval. The marketing
approval processes in other countries may include all of  the risks detailed  above regarding FDA
approval in the U.S. as well as other risks, or  vice versa. In particular, in  many countries outside of the
U.S., products must receive pricing and  reimbursement approval before the product  can be
commercialized. Obtaining this approval can result in  substantial delays in bringing products to market
in such countries. Marketing approval in  one country does  not ensure marketing  approval in another,
but a failure or delay in obtaining marketing approval in  one country may  have a negative effect on the
regulatory process in others. Failure to obtain  marketing  approval  in other countries or  any delay or
other setback in obtaining such approval would impair  our ability to commercialize bempedoic acid in
such foreign markets. Any such impairment would reduce the size of our  potential market, which  could
have a material adverse impact on our business, results of operations and prospects.

Even if we receive marketing approval for  bempedoic  acid, it may  not  achieve broad  market acceptance, which
would limit the revenue that we generate  from its sales.

The commercial success of bempedoic  acid, if approved by  the FDA or other regulatory
authorities, will depend upon the awareness and acceptance of bempedoic acid among the medical
community, including physicians, patients and healthcare  payors. Market acceptance of bempedoic acid,
if approved, will depend on a number  of factors, including, among others:

• bempedoic acid’s demonstrated ability to treat  ‘‘statin  intolerant’’  patients  for LDL-C lowering

or CV  risk reduction as an add-on for patients already on statin therapy, as  compared with  other
available therapies;

• the relative convenience and ease of administration of bempedoic acid, including as compared

with other treatments for patients for  LDL-C  lowering or CV risk reduction;

• the prevalence and severity of any  adverse side  effects such as muscle  pain or  weakness;

• limitations or warnings contained in the labeling approved for bempedoic acid by the  FDA;

34

• availability of alternative treatments, including a number  of  competitive therapies already

approved for LDL-C lowering or CV risk reduction, including PCSK9 inhibitors, or  expected to
be commercially launched in the near future;

• pricing and cost effectiveness;

• the effectiveness of our sales and marketing strategies;

• our ability to increase awareness of  bempedoic acid through marketing efforts;

• our ability to obtain sufficient third-party coverage  or reimbursement; and

• the willingness of patients to pay out-of-pocket in  the absence of  third-party coverage.

If bempedoic acid is approved but does not achieve  an adequate level  of acceptance by patients,

physicians and payors, we may not generate sufficient revenue  from  bempedoic acid  to  become or
remain profitable. Our efforts to educate the  medical community and third-party payors about  the
benefits of bempedoic acid may require significant  resources and may never be successful.

If we are unable to establish sales and  marketing capabilities or  enter into agreements  with third parties to
market and sell bempedoic acid, we may not be able  to generate  any revenue.

We  do not currently have an infrastructure for the sales, marketing  and distribution of

pharmaceutical products. In order to market bempedoic acid, if approved by the FDA or any other
regulatory body, we must build our sales, marketing, managerial, and other non-technical capabilities or
make arrangements with third parties to perform these services. If we  are unable  to  establish adequate
sales, marketing and distribution capabilities, whether independently or with  third parties, or if we  are
unable to do so on commercially reasonable terms, our business,  results of operations, financial
condition and prospects will be materially adversely affected.

Even if we obtain marketing approval for bempedoic acid, physicians  and patients using other LDL-C
lowering therapies may choose not to switch  to our product.

Physicians are often reluctant to switch their patients from existing therapies even when new and
potentially more effective, safe or convenient treatments  enter the market. In addition, patients often
acclimate to the brand or type of therapy  that  they  are currently taking and  do not want to switch
unless their physicians recommend switching  products or  they are required to switch therapies due to
lack of reimbursement for existing therapies. If physicians  or patients are  reluctant  to  switch  from
existing therapies to bempedoic acid, if  approved,  our operating  results and financial condition would
be materially adversely affected.

The development and, if approved, commercialization of BA  + EZ depends on the availability to and use of
ezetimibe by the target patient of this combination therapy.

BA + EZ is dependent on the continued  availability and use of ezetimibe  in the marketplace, and
there can be no assurance that the current  availability and  use of ezetimibe will continue. For  example,
changes in standard of care or use patterns of ezetimibe  could make  our BA + EZ combination
therapy obsolete. In addition, ezetimibe could encounter unexpected results  in the future and  be
associated with adverse outcomes during  long-term use. Finally, the  producers of ezetimibe  are under
no obligation to continue producing, commercializing or making ezetimibe available to patients, or to
continue producing ezetimibe in any  particular quantity, which could prevent our ability to obtain
ezetimibe for use in our planned clinical trials or  impact the number of patients taking ezetimibe who
are available to enroll in our clinical  trials.  For example, such producers may encounter  manufacturing
or other  production issues and fail to produce  enough ezetimibe for us to successfully complete our

35

studies and clinical trials, and this could cause our BA + EZ development program or
commercialization efforts, if BA + EZ is approved, to fail  or be significantly delayed.

Guidelines and recommendations published by various  organizations may adversely  affect the  FDA’s review of
bempedoic acid for LDL-C lowering in  ‘‘statin intolerant’’  patients  or the  use  or commercial  viability  of
bempedoic acid, if approved for any indication or patient population.

Government agencies issue regulations and  guidelines directly  applicable  to  us  and to bempedoic

acid, including guidelines generally relating to therapeutically significant LDL-C levels.  In  addition,
professional societies, practice management groups,  private health or science foundations  and other
organizations involved in the research,  treatment and prevention of various  diseases  from time  to  time
publish guidelines or recommendations to the medical and patient  communities. These various sorts of
recommendations may relate to such matters  as product  usage and use of related  or competing
therapies. For example, organizations such as the AHA have made recommendations about therapies in
the cardiovascular therapeutics market. We expect that the FDA’s view of the standard  of care  for
patients with elevated LDL-C at the  time we submit an NDA for our LDL-C-lowering program in
patients with elevated LDL-C will impact  the evaluation of such NDA, including how this standard of
care evolves in light of guidelines and recommendations  in  respect of the use of PCSK9 inhibitors. In
addition, following any approval, we  expect  that changes to these  existing recommendations  or other
guidelines advocating alternative therapies  could result in  decreased  use of  bempedoic acid, which
would adversely affect our results of operations.

Even if approved, reimbursement policies could  limit our ability  to sell  bempedoic acid.

Market acceptance and sales of bempedoic acid will depend  on reimbursement policies and may be
affected by healthcare reform measures. Government  authorities and third-party payors, such  as private
health insurers and health maintenance  organizations, decide which medications  they will pay for and
establish reimbursement levels for those medications.  Cost containment  is a primary concern in the
U.S. healthcare industry and elsewhere. Government authorities  and  these third-party payors have
attempted to control costs by limiting coverage and  the amount  of reimbursement for particular
medications. We cannot be sure that  reimbursement will be available for bempedoic acid and, if
reimbursement is available, the level of  such reimbursement. Reimbursement may impact the  demand
for, or the price of, bempedoic acid.  If  reimbursement  is not  available  or is  available only at limited
levels, we may not be able to successfully commercialize  bempedoic  acid.

In some foreign countries, particularly in Canada  and European  countries, the pricing of
prescription pharmaceuticals is subject  to strict governmental  control. In  these countries,  pricing
negotiations with governmental authorities can take six  to  12 months or longer after the  receipt of
regulatory approval and product launch.  To  obtain  favorable reimbursement for the indications sought
or pricing approval in some countries,  we may be required  to  conduct a  clinical study that compares
the cost-effectiveness of bempedoic acid with  other  available  therapies. If  reimbursement for bempedoic
acid is unavailable in any country in which we  seek reimbursement, if  it is  limited  in scope or amount,
if it  is  conditioned upon our completion of additional clinical  studies, or if pricing is set at
unsatisfactory levels, our operating results could be materially adversely affected.

Our future product development programs  for candidates other than bempedoic acid  may require substantial
financial resources and may ultimately be  unsuccessful.

In addition to the development of bempedoic acid, we may  in the future pursue the  development
of other early-stage development programs. Our  potential product candidate has  not  commenced  any
clinical studies, and there are a number  of FDA  requirements that  we  must satisfy before we can
commence such clinical studies. Satisfaction of these requirements will entail substantial time,  effort
and financial resources. We may never  satisfy  these requirements. Any time, effort and financial

36

resources we expend on any early-stage  development programs that  we  may pursue may adversely
affect our ability to continue development  and  commercialization of bempedoic acid, and we  may never
commence clinical studies of such development  programs  despite expending significant resources in
pursuit of their development. If we do  commence clinical studies of our other potential product
candidates, such product candidates may never be approved by the FDA.

Recent federal legislation will increase pressure to reduce prices  of pharmaceutical products paid  for by
Medicare, which could materially adversely  affect our revenue, if any, and our results of  operations.

In the United States, the Medicare Prescription Drug, Improvement, and Modernization Act of
2003, also called the MMA, changed the way Medicare  covers and pays  for  pharmaceutical products.
The legislation expanded Medicare coverage for drug purchases  by the elderly and  introduced  a new
reimbursement methodology based on average sales prices  for physician-administered drugs. In
addition, this legislation provided authority for limiting the  number of drugs that will  be  covered in  any
therapeutic class. As a result of this legislation and the expansion of  federal coverage of drug products,
we expect that there will be additional  pressure to reduce costs. These cost reduction initiatives and
other provisions of this legislation could  decrease the scope  of  coverage and the price that we receive
for any approved products and could  seriously harm our business. While the  MMA applies only to drug
benefits for Medicare beneficiaries, private payors often follow  Medicare coverage policies and payment
limitations in setting their own reimbursement rates, and any  reduction  in reimbursement that results
from the MMA may cause a similar reduction in payments from  private payors.  This legislation  may
pose an even greater risk to bempedoic acid  than some other pharmaceutical products because  a
significant portion of the target patient  population  for  bempedoic acid would likely be over 65 years of
age and, therefore, many such patients will be covered  by Medicare.

In March 2010, the Patient Protection and Affordable  Care Act, as amended by the  Health Care
and Education Affordability Reconciliation Act, or collectively, the PPACA, became law in the  United
States. The goal of the PPACA is to reduce the cost  of  healthcare and substantially  change the way
healthcare is financed by both governmental and  private insurers. While we cannot predict what  impact
on federal reimbursement policies this legislation will have in general or  on our business specifically,
the PPACA may result in downward pressure  on pharmaceutical  reimbursement, which could negatively
affect market acceptance of bempedoic  acid, if  approved, or any of our  future  products. In 2012,
members of the U.S. Congress and some state legislatures sought to overturn certain provisions of the
PPACA including those concerning the  mandatory purchase of insurance. However,  on June 28, 2012,
the United States Supreme Court upheld the  constitutionality of these  provisions.  Members of the  U.S.
Congress have since proposed a number of legislative initiatives,  including  possible  repeal of the
PPACA. We cannot predict the outcome or impact of  current  proposals or whether new proposals  will
be made or adopted, when they may  be  adopted or what impact  they may have  on us if they are
adopted. These challenges add to the  uncertainty of the  legislative changes  as part of ACA.

Finally, the availability of generic LDL-C  lowering treatments may also substantially reduce the
likelihood of reimbursement for branded counterparts or other competitive LDL-C lowering  therapies,
such as bempedoic acid if it is approved for commercial  distribution. If  we  fail to successfully secure
and maintain reimbursement coverage for our products or  are significantly delayed in doing so, we will
have difficulty achieving market acceptance of our products and our business will be harmed.

Recent federal legislation and actions by  state and local governments may permit reimportation of drugs from
foreign countries into the United States, including foreign  countries where the drugs are sold at lower prices
than in the United States, which could materially adversely affect our operating results.

We  may face competition for bempedoic acid, if approved, from cheaper  LDL-C lowering
therapies sourced from foreign countries that  have placed price controls on  pharmaceutical products.
The MMA contains provisions that may  change U.S.  importation laws and expand pharmacists’  and

37

wholesalers’ ability to import cheaper  versions of an  approved drug and competing  products from
Canada, where there are government  price controls. These changes to U.S. importation laws will not
take effect unless and until the Secretary of  Health and  Human Services certifies that the changes will
pose no additional risk to the public’s health and safety and will  result in a  significant reduction in the
cost of products to consumers. The Secretary of Health and Human Services  has so far declined to
approve a reimportation plan. Proponents  of  drug reimportation  may  attempt to pass legislation that
would directly allow reimportation under  certain circumstances. Legislation or  regulations allowing the
reimportation of drugs, if enacted, could decrease  the price we receive for any  products that we may
develop, including bempedoic acid, and adversely  affect our future  revenues and prospects for
profitability.

The FDA and other regulatory agencies actively enforce the laws and regulations prohibiting the promotion  of
off-label uses. If we are found to have improperly promoted  off-label  uses, we may become subject to
significant liability.

The FDA and other regulatory agencies  strictly regulate the promotional  claims that may be made

about prescription  products, such as  bempedoic acid if approved. In particular, a  product may not be
promoted for uses that are not approved by  the FDA  or other regulatory agencies as reflected  in the
product’s approved labeling. If we receive  marketing  approval  for bempedoic acid as a  therapy for
lowering LDL-C levels in ‘‘statin intolerant’’  patients with  elevated LDL-C,  the first indication  we
intend to pursue, physicians may nevertheless prescribe bempedoic acid to their patients in  a manner
that is inconsistent with the approved  label, potentially including as  a  therapy  in addition to statins. If
we are found to have promoted such off-label uses,  we may become  subject to significant  liability.  The
federal government has levied large civil and criminal fines  against companies  for alleged improper
promotion and has enjoined several companies  from engaging in  off-label promotion. The  FDA has
also requested that companies enter into  consent  decrees, corporate integrity agreements  or permanent
injunctions under which specified promotional  conduct is changed or  curtailed. If we cannot
successfully manage the promotion of bempedoic acid, if approved, we could become subject to
significant liability, which would materially adversely affect our business  and financial condition.

Our market is subject to intense competition. If we are unable to compete effectively,  our opportunity  to
generate revenue from the sale of bempedoic acid,  if approved,  will be materially  adversely  affected.

The LDL-C lowering therapies market is highly  competitive and dynamic and dominated  by  the
sale of statin treatments, including the cheaper  generic versions of statins.  We estimate that the total
statin monotherapy and fixed combination market, including generic drugs, accounted for 69% of U.S.
sales in the LDL-C lowering market in  2012. Our success will  depend,  in part,  on our ability to obtain
a share of the market, initially, for patients who are ‘‘statin intolerant’’. Potential competitors in North
America, Europe and elsewhere include major pharmaceutical companies,  specialty pharmaceutical
companies, biotechnology firms, universities  and other  research institutions and  government agencies.
Other pharmaceutical companies may  develop LDL-C lowering therapies  for ‘‘statin  intolerant’’
patients that compete with bempedoic  acid, if  approved, that do not infringe the claims  of  our  patents,
pending patent applications or other proprietary rights, which could materially adversely  affect our
business and results of operations. The  FDA has also  indicated to us  that approval of other therapies
that may be taken by ‘‘statin intolerant’’ patients could have  an impact on  their  review of an NDA we
submit for bempedoic acid for our LDL-C lowering  program in these patients.

LDL-C lowering therapies currently on the  market  that would compete with bempedoic acid

include the following:

• Branded statins and their cheaper generic versions;

38

• Cholesterol absorption inhibitors, such as  Zetia(cid:4) (ezetimibe), a monotherapy marketed by

Merck & Co., and the cheaper generic version;

• PCSK9 inhibitors such as Praluent(cid:4) (alirocumab) and Repatha(cid:4) (evolocumab), marketed by

Sanofi/Regeneron and Amgen Inc. respectively;

• Bile acid sequestrants such as Welchol(cid:4) (colesevelam), marketed by Daiichi Sankyo Inc.;
• MTP inhibitors, such as JUXTAPID(cid:4) (lomitapide), marketed by Novelion Therapeutics,  Inc.;
• Apo B Anti-Sense therapy, such as KYNAMRO(cid:4) (mipomersen), marketed by Kastle

Therapeutics LLC;

• Combination therapies, such as Vytorin(cid:4) (ezetimibe and simvastatin) and Liptruzet(cid:4) (ezetimibe

and atorvastatin), marketed by Merck &  Co., Inc.;  and

• Other lipid-lowering monotherapies (including cheaper  generic versions), such as Tricor(cid:4)
(fenofibrate) and Niaspan(cid:4) (niacin extended release), both of which are marketed by
AbbVie, Inc.

Several other pharmaceutical companies have other LDL-C lowering  therapies in development that

may be approved for marketing in the  U.S.  or outside of the U.S. Based on publicly available
information, we believe the current therapies in development that would compete with bempedoic acid
include:

• PCSK9 inhibitors in development from Lilly, Roche, Kowa  and The Medicines Company/

Alnylam; and

• CETP inhibitors, such as anacetrapib  and  dalcetrapib, therapies, in Phase 3 clinical testing  being

developed by Merck and DalCor, respectively.

Many of our potential competitors have substantially greater financial, technical and human
resources than we do and significantly greater  experience  discovering and developing drug candidates,
obtaining FDA and other marketing  approvals of  products and commercializing those products.
Accordingly, our competitors may be  more successful than we  may  be  in obtaining FDA approval for
drugs and achieving widespread market acceptance. Our competitors’  drugs may be more effective, or
more effectively marketed and sold, than bempedoic acid, if approved, and may render bempedoic acid
obsolete  or non-competitive before we  can recover the  expenses of developing and commercializing it.
If approved, bempedoic acid may also compete  with unapproved and off-label  LDL-C lowering
treatments, and following the expiration of additional patents covering the LDL-C lowering  market, we
may also face additional competition  from the entry  of new generic drugs. We anticipate  that  we will
encounter intense and increasing competition as new drugs enter the market and advanced  technologies
become  available.

We face potential product liability exposure,  and, if claims are brought against  us, we may incur substantial
liability.

The use of bempedoic acid in clinical studies and  the sale of bempedoic acid,  if approved, exposes
us to the risk of product liability claims. Product liability claims might be brought  against us by patients,
healthcare providers or others selling or  otherwise coming into contact with bempedoic acid. For
example, we may be sued if any product we  develop allegedly causes injury or is found to be otherwise
unsuitable during product testing, manufacturing,  marketing  or sale. Any  such product liability claims
may include allegations of defects in manufacturing, defects in design, a  failure to warn of  dangers
inherent in the product, including as  a result of  interactions with alcohol or other drugs, negligence,
strict liability, and a breach of warranties. Claims could  also be asserted under  state consumer
protection acts. If we become subject  to  product liability claims and cannot successfully defend

39

ourselves  against them, we could incur  substantial  liabilities. In addition, regardless of merit  or eventual
outcome, product liability claims may  result  in, among other things:

• withdrawal of patients from our clinical  studies;

• substantial monetary awards to patients or other claimants;

• decreased demand for bempedoic acid  or any future product candidates following marketing

approval, if obtained;

• damage to our reputation and exposure  to  adverse publicity;

• increased FDA warnings on product labels;

• litigation costs;

• distraction of management’s attention from our primary business;

• loss of revenue; and

• the inability to successfully commercialize bempedoic acid or any future  product candidates, if

approved.

We  maintain product liability insurance  coverage for our  clinical studies  with a $10.0  million
annual aggregate coverage limit. Nevertheless, our insurance  coverage may be insufficient to reimburse
us for any expenses or losses we may  suffer. Moreover, in the future, we  may not be able to maintain
insurance coverage at a reasonable cost or  in sufficient  amounts to protect  us against losses, including
if insurance coverage becomes increasingly  expensive. If and when we  obtain marketing approval for
bempedoic  acid, we intend to expand  our insurance  coverage to include the sale  of  commercial
products; however, we may not be able  to  obtain  this  product  liability  insurance on  commercially
reasonable terms. Large judgments have been awarded in class action lawsuits based  on drugs that had
unanticipated side effects. The cost of  any product  liability litigation or other proceedings,  even if
resolved  in our favor, could be substantial,  particularly in light of the size of our business and  financial
resources. A product liability claim or  series  of claims brought against us  could  cause  our stock  price to
decline  and, if we  are unsuccessful in  defending  such a claim  or claims and the resulting judgments
exceed our insurance coverage, our financial  condition, business and prospects could be materially
adversely affected.

We are subject to healthcare laws and regulations,  which could expose us to criminal sanctions, civil  penalties,
contractual damages, reputational harm  and diminished profits  and  future  earnings.

Healthcare providers, physicians and  others will  play a primary role in  the recommendation  and

prescription of bempedoic acid, if approved.  Our  future arrangements  with third-party payors  will
expose us to broadly applicable fraud  and  abuse and other  healthcare  laws  and regulations that may
constrain the business or financial arrangements  and relationships through which we market, sell  and
distribute bempedoic acid, if we obtain marketing approval. Restrictions under applicable federal and
state healthcare laws and regulations  include the following:

• The federal healthcare anti-kickback statute prohibits,  among other things, persons from

knowingly and willfully soliciting, offering, receiving or providing  remuneration, directly or
indirectly, in cash or in kind, to induce or reward either the referral of an  individual for,  or  the
purchase, order or recommendation of, any good or service, for which  payment may  be  made
under federal healthcare programs such as  Medicare  and Medicaid.

• The federal False Claims Act imposes criminal and  civil penalties,  including those from civil
whistleblower or qui tam actions, against individuals or  entities for knowingly  presenting,  or
causing  to be presented, to the federal government, claims for  payment that are false or

40

fraudulent or making a false statement to avoid, decrease,  or conceal  an obligation to pay  money
to the federal government.

• The federal Health Insurance Portability and Accountability Act of 1996,  as amended  by  the

Health Information Technology for Economic and Clinical  Health Act, imposes criminal and  civil
liability for executing a scheme to defraud any healthcare  benefit program and also  imposes
obligations, including mandatory contractual terms,  with respect to safeguarding the privacy,
security and transmission of individually identifiable health information.

• The federal false statements statute prohibits knowingly and willfully falsifying, concealing or
covering up a material fact or making any materially false statement in connection with the
delivery of or payment for healthcare benefits,  items or services.

• The federal transparency requirements  under the PPACA require manufacturers of drugs,

devices, biologics, and medical supplies to report  to  the Department of Health and  Human
Services information related to physician payments  and other transfers of value and physician
ownership and investment interests.

• Analogous state laws and regulations, such as state anti-kickback and false claims laws and

transparency laws, may apply to sales or  marketing arrangements  and claims involving healthcare
items or services reimbursed by non-governmental  third-party  payors, including  private insurers,
and some state laws require pharmaceutical companies  to  comply with the pharmaceutical
industry’s voluntary compliance guidelines and the relevant compliance guidance  promulgated  by
the federal government in addition to requiring drug manufacturers  to  report information
related to payments to physicians and other healthcare providers or marketing  expenditures  and
drug pricing.

Ensuring that our future business arrangements with third parties  comply with applicable

healthcare laws and regulations could  be costly.  It is possible that governmental authorities will
conclude that our business practices do not comply with current or  future statutes, regulations or  case
law involving applicable fraud and abuse or  other healthcare laws and  regulations.  If our operations,
including anticipated activities to be conducted by our sales team, were found to be in violation of any
of these  laws or any other governmental regulations that may  apply to us, we may be subject  to
significant civil, criminal and administrative penalties, damages, fines and exclusion from government
funded healthcare  programs, such as Medicare and Medicaid, any  of  which could substantially disrupt
our  operations. If any of the physicians or other providers or entities with  whom  we expect to do
business is found not to be in compliance with  applicable laws, they may be subject to criminal, civil or
administrative sanctions, including exclusions from  government funded healthcare programs.

Our internal computer systems, or those  of our  third-party  clinical research organizations or other contractors
or consultants, may fail or suffer security breaches, which could result in a material  disruption of our
bempedoic acid development programs.

Despite the implementation of security measures, our internal computer systems and those of our

third-party clinical research organizations and  other contractors and consultants are vulnerable  to
damage  from computer viruses, unauthorized  access, natural disasters, terrorism, war, and
telecommunication and electrical failures. While we  have not  experienced any such system failure,
accident, or security breach to date, if such an  event were to occur and  cause interruptions in  our
operations, it could result in a material disruption of our  programs. For  example, the loss of clinical
study data for bempedoic acid could result in delays in our regulatory approval efforts  and significantly
increase our costs to recover or reproduce the  data. To the extent  that any  disruption or security  breach
results in  a loss of or damage to our  data or applications  or  other data or applications relating to our
technology or product candidates, or inappropriate  disclosure of confidential or proprietary
information, we could incur liabilities  and  the further development of bempedoic acid could be delayed.

41

Our credit facility imposes significant restrictions on our  business,  and  if  we default on  our  obligations,  our
lender would have a right to foreclose on  substantially all our assets.

In June 2014, we entered into a loan and security agreement, or loan agreement, with Oxford
Finance LLC, or Oxford, pursuant to  which,  subject to the conditions to borrowing thereunder,  we
borrowed an aggregate principal amount of $5.0 million. The loans  are  secured by a  lien on
substantially all of our assets excluding  intellectual  property.

We  could in the future incur additional indebtedness beyond amounts  currently outstanding under

our  loan agreement with Oxford. Our  debt combined with our  other financial obligations and
contractual commitments could have  significant adverse consequences, including:

• requiring us to dedicate a substantial portion of cash flow from operations to the payment of

interest on, and principal of, our debt, which will reduce the amounts available  to  fund  working
capital, capital expenditures, product development efforts  and  other general corporate  purposes;

• increasing our vulnerability to adverse changes in general economic, industry and market

conditions;

• limiting our flexibility in planning for, or  reacting to, changes in our business and the industry in

which we compete; and

• placing us at a competitive disadvantage compared to our  competitors that have less debt or

better debt servicing options.

Additionally, with certain exceptions, the  loan agreement  prohibits  us from:

• making any material dispositions of our assets, except for permitted dispositions;

• making any changes in our business, management, ownership, or business locations;

• entering into any merger or consolidation without Oxford’s consent;

• acquiring or making investments in  any  other  person other than  permitted investments;

• incurring any indebtedness, other than permitted indebtedness;

• granting or permitting liens against our  assets, other than permitted  liens;

• declaring or paying any dividends or making any other distributions;  or

• entering into any material transaction with any affiliate,  other than in the  ordinary course of

business.

We  intend to satisfy our current and  future debt service obligations with  our cash and cash
equivalents and short-term investments  and funds from external sources. However, we may not have
sufficient funds or may be unable to arrange for  additional  financing to pay the  amounts due under our
existing debt. Funds from external sources may not be available on  acceptable terms, if  at all. In
addition, a failure to comply with the covenants under our debt instruments could result in an event of
default under those instruments. In the event of  an acceleration  of amounts due under  our debt
instruments as a result of an event of  default,  we may  not  have sufficient funds and may be unable to
arrange for additional financing to repay our indebtedness, and our lender could seek to enforce
security interests in the collateral securing such indebtedness. In addition, the covenants  under our debt
instruments and the pledge of our assets as collateral limit our  ability to obtain  additional debt
financing.

42

Risks Related to our Intellectual Property

If we are unable to adequately protect our proprietary technology or maintain issued patents which are
sufficient to protect bempedoic acid, others  could compete against  us more directly,  which would have a
material adverse impact on our business,  results  of operations, financial condition and prospects.

Our commercial success will depend in  part on our  success obtaining and maintaining issued
patents and other intellectual property  rights in the  United States and elsewhere and protecting our
proprietary technology. If we  do not  adequately protect our intellectual property and proprietary
technology, competitors may be able to use our technologies and erode  or negate any competitive
advantage we may have, which could harm our business  and ability to achieve profitability.

As of December 31, 2016, our patent estate, including patents  we own or license from third

parties, on a worldwide basis, included  approximately  25 issued United States patents and four pending
United States patent applications and  23 issued patents and 15  pending  patent  applications in other
foreign jurisdictions. Of our worldwide patents and pending applications, only a subset relates to our
small molecule program which includes  our  lead product candidate, bempedoic acid. Bempedoic  acid is
claimed in U.S. Patent No. 7,335,799 that is scheduled  to  expire in  December 2025, which includes
711 days of patent term adjustment,  and may be eligible for a patent term extension period of up to
five years. U.S. Patent Nos. 9,000,041  and  8,497,301 claim methods of treatment using bempedoic acid.
We  also have a pending U.S. patent application  directed to bempedoic acid. There are  currently three
issued patents and four pending application in countries outside the United States that relate to
bempedoic acid.

A subset of this portfolio relates to our planned fixed dose combination of bempedoic acid and

ezetimibe and bempedoic acid and one or more statins. We have one pending application outside the
United States claiming methods of treatment  using a fixed dose combination of bempedoic  acid and
ezetimibe. We have one pending application outside the United States claiming methods  of treatment
using a fixed dose combination of bempedoic acid and  one  or more statins.

We  may not have identified all patents, published  applications or published literature that affect

our  business either by blocking our ability to commercialize our drug candidates,  by  preventing the
patentability of one or more aspects  of  our  drug candidates to us or  our licensors or co-owners, or by
covering the same or similar technologies that  may  affect our ability to market our drug candidates. For
example, we (or the licensor of a drug  candidate to us) may not have conducted a patent clearance
search to identify potentially obstructing  third party patents. Moreover, patent applications in the
United States are maintained in confidence  for up to 18 months  after their filing. In some cases,
however, patent applications remain  confidential in the  U.S. Patent  and Trademark Office, or the
U.S. PTO, for the  entire time prior to issuance as a  U.S. patent. Patent applications filed in countries
outside of the United States are not  typically  published  until at least 18 months from their  first  filing
date.  Similarly, publication of discoveries in the scientific or patent literature often lags behind actual
discoveries. We cannot be certain that  we or  our licensors or  co-owners were the first to invent, or the
first to file, patent applications covering our drug candidates. We also  may not know if our  competitors
filed patent applications for technology covered by  our pending applications or  if we were the first to
invent the technology that is the subject of our  patent  applications. Competitors may have filed patent
applications or received patents and may  obtain additional  patents and proprietary rights that block or
compete with our patents.

Others may have filed patent applications or received  patents that conflict with patents or  patent

applications that we own, have filed or have licensed, either by claiming the same methods, compounds
or uses or by claiming methods, compounds or uses that could dominate  those  owned by or licensed to
us. In addition, we may not be aware  of all patents or patent applications that may affect our ability to
make, use or sell any of our drug candidates.  Any conflicts resulting from third-party patent
applications and patents could affect  our ability  to  obtain the necessary patent protection for our

43

products or processes. If other companies  or entities obtain patents  with conflicting  claims,  we may be
required to obtain licenses to these patents or to develop or obtain alternative technology.  We  may not
be able to obtain any such licenses on acceptable terms or  at  all. Any failure to obtain such  licenses
could delay or prevent us from using discovery-related  technology to pursue the development  or
commercialization of our drug candidates, which would adversely affect  our business.

We  cannot assure you that any of our patents have, or  that  any of our pending patent applications

will mature into issued patents that will  include, claims with  a  scope  sufficient to protect  bempedoic
acid or any other product candidates.  Others  have developed technologies that may be related or
competitive to our approach, and may  have filed or may file patent applications and may have  received
or may receive patents that may overlap or  conflict  with our patent applications, either by claiming the
same methods or formulations or by  claiming subject matter that could  dominate our patent position.
The patent positions of biotechnology and pharmaceutical companies, including our  patent  position,
involve complex legal and factual questions, and,  therefore, the issuance, scope, validity and
enforceability of any patent claims that we may obtain cannot be predicted with certainty. Patents,  if
issued, may be challenged, deemed unenforceable,  invalidated, or circumvented. U.S. patents and
patent applications may also be subject to interference proceedings, ex parte reexamination, inter  partes
review and post-grant review proceedings, supplemental examination  and may be challenged  in district
court. Patents granted in certain other  countries  may  be  subjected  to  opposition or comparable
proceedings lodged in various national and regional patent offices. These proceedings  could  result in
either loss of the patent or denial of the  patent  application or loss or reduction in the  scope of one or
more of the claims of the patent or patent application. In addition, such  interference,  re-examination,
opposition, post-grant review, inter partes  review, supplemental examination or revocation  proceedings
may be costly. Thus, any patents that we may own or exclusively license may not provide any protection
against competitors. Furthermore, an  adverse decision in  an interference  proceeding can result in  a
third-party receiving the patent right  sought by us, which  in  turn  could affect our ability to develop,
market or otherwise commercialize bempedoic acid.

Furthermore, the issuance of a patent, while presumed  valid and enforceable,  is not conclusive as

to its validity or its enforceability and  it  may not provide us with adequate proprietary  protection or
competitive advantages against competitors with similar products. Competitors  may also be able to
design around our patents. Other parties may develop and obtain  patent  protection for more effective
technologies, designs or methods. We  may not be able to prevent the unauthorized  disclosure or use of
our  technical knowledge or trade secrets by consultants, vendors, former employees  and current
employees. The laws of some foreign  countries do not protect our proprietary rights to the  same extent
as the laws of the United States, and  we may encounter significant  problems in protecting our
proprietary rights in these countries.  If  these developments were to occur, they  could  have a material
adverse effect on our sales.

Our ability to enforce our patent rights  depends  on our ability to detect  infringement. It is difficult

to detect  infringers who do not advertise the components that are used in their products.  Moreover, it
may be difficult or impossible to obtain  evidence of  infringement  in a competitor’s or  potential
competitor’s product. Any litigation to  enforce or  defend our patent rights,  if  any, even if we  were  to
prevail, could be costly and time-consuming and would divert the attention of our management and  key
personnel from our business operations. We may not prevail in any lawsuits that we initiate  and the
damages or other remedies awarded if we  were to prevail  may not be commercially meaningful.

In addition, proceedings to enforce or defend our patents could  put  our patents at risk of being
invalidated, held unenforceable, or interpreted narrowly. Such  proceedings could also provoke third
parties to assert claims against us, including that some or all  of the claims in one or more of  our
patents are invalid or otherwise unenforceable. If, in any proceeding, a court invalidated or  found
unenforceable our patents covering bempedoic acid,  our  financial  position and results  of  operations
would be materially and adversely impacted. In  addition,  if a court found that valid, enforceable patents

44

held by third parties covered bempedoic  acid, our  financial  position and results  of operations  would
also be materially and adversely impacted.

The degree of future protection for our  proprietary  rights is uncertain, and we cannot  ensure that:

• any of our patents, or any of our pending patent applications, if issued, will include claims

having a scope sufficient to protect bempedoic  acid;

• any of our pending patent applications will result in  issued patents;

• we will be able to successfully commercialize  bempedoic acid, if  approved, before our relevant

patents expire;

• we were the first to make the inventions covered by each  of  our patents and  pending  patent

applications;

• we were the first to file patent applications for these inventions;

• others will not develop similar or  alternative technologies that  do not infringe our patents;

• any of our patents will be valid and enforceable;

• any patents issued to us will provide a  basis for an  exclusive market for our commercially viable
products, will provide us with any competitive  advantages  or will not be challenged by third
parties;

• we will develop additional proprietary technologies  or product  candidates that are separately

patentable; or

• that our commercial activities or products, or those of our licensors, will  not  infringe  upon the

patents of others.

We  rely upon unpatented trade secrets, unpatented  know-how and continuing technological
innovation to develop and maintain our  competitive position, which we seek  to  protect, in part, by
confidentiality agreements with our employees and  our  collaborators and consultants. We  also have
agreements with our employees and selected consultants that obligate  them to assign their inventions to
us. It is possible that technology relevant to our business will be independently developed by a  person
that is not a party to such an agreement.  Furthermore,  if the employees  and consultants  who are
parties to these agreements breach or  violate the terms of these agreements,  we may not have  adequate
remedies for any such breach or violation, and we could lose our trade secrets through such  breaches
or violations. Further, our trade secrets  could otherwise  become  known or be independently discovered
by our competitors.

If we are not able to adequately prevent  disclosure of trade secrets and other proprietary information, the
value of our technology and products could be significantly  diminished.

We  rely on trade secrets to protect our  proprietary  technologies, especially where we do  not
believe patent protection is appropriate  or obtainable. However, trade secrets are difficult to protect.
We  rely  in part on confidentiality agreements with our  employees, consultants, outside scientific
collaborators, sponsored researchers,  contract manufacturers, vendors and other advisors to protect our
trade secrets and other proprietary information. These  agreements may not effectively prevent
disclosure of confidential information and may not provide an adequate remedy  in the event of
unauthorized disclosure of confidential information. In  addition, we cannot guarantee that we have
executed these agreements with each party that may have or have had access  to  our  trade secrets.

Moreover, because we acquired certain rights  to  our  lead product  candidate from Pfizer, we must

rely on Pfizer’s practices, and those of  its predecessors,  with regard to parties that may have had access
to our trade secrets related thereto before our incorporation. Any party  with whom we or  they have

45

executed such an agreement may breach that agreement  and disclose our proprietary  information,
including our trade secrets, and we may  not  be  able  to  obtain adequate  remedies for such  breaches.
Enforcing a claim that a party illegally disclosed or misappropriated a trade secret  is difficult, expensive
and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the
United States are less willing or unwilling to protect trade  secrets. If any  of our trade  secrets  were to
be lawfully obtained or independently developed  by a  competitor, we would have  no right  to  prevent
them, or those to whom they disclose such trade secrets, from using that technology or information to
compete with us. If any of our trade secrets  were to be disclosed to or independently developed by a
competitor or other third-party, our  competitive position would be harmed.

We may  infringe the intellectual property rights of others, which may prevent or delay our product development
efforts and stop us from commercializing or increase  the costs of commercializing  bempedoic acid, if
approved.

Our success will depend in part on our  ability to operate without infringing the intellectual
property and proprietary rights of third parties. We cannot assure you  that our business, products  and
methods do not or will not infringe the  patents or other intellectual  property  rights of third parties.

The pharmaceutical industry is characterized by extensive litigation regarding patents and  other

intellectual property rights. Other parties may allege that bempedoic acid or the  use of our
technologies infringes patent claims or  other  intellectual  property rights held by them or that we  are
employing their proprietary technology  without  authorization.  Patent and other types of intellectual
property litigation can involve complex factual and  legal questions, and their  outcome is uncertain. Any
claim relating to intellectual property  infringement that is  successfully  asserted against us  may require
us to pay substantial damages, including  treble damages  and attorney’s fees if we  are found to be
willfully infringing another party’s patents,  for past  use of the asserted intellectual  property and
royalties and other consideration going  forward if we are  forced to take a license. In addition, if any
such claim were successfully asserted  against us and  we could  not obtain such  a license,  we may be
forced to  stop or delay developing, manufacturing, selling  or  otherwise commercializing bempedoic
acid.

Even if we are successful in these proceedings, we may incur substantial  costs and divert

management time and attention in pursuing  these  proceedings, which could have a  material  adverse
effect on us. If we are unable to avoid  infringing the  patent rights of others, we  may be required  to
seek a license, defend an infringement action or challenge  the validity of  the patents in court, or
redesign our products. Patent litigation is costly and  time consuming. We  may not have sufficient
resources to bring these actions to a successful  conclusion. In addition, intellectual property litigation or
claims could force us to do one or more of the following:

• cease developing, selling or otherwise commercializing bempedoic acid;

• pay substantial damages for past use of  the asserted  intellectual property;

• obtain a license from the holder of the  asserted  intellectual property, which license may not be

available on reasonable terms, if at all;  and

• redesign, or rename in the case of  trademark  claims, bempedoic acid  to avoid infringing the
intellectual property rights of third parties, which  may not be possible and, even if  possible,
could be costly and time-consuming.

Any of these risks coming to fruition could  have a material  adverse effect on our  business,  results

of operations, financial condition and prospects.

46

Changes in U.S. patent law could diminish  the value of  patents in general, thereby impairing our ability  to
protect our products.

The United States has enacted and is currently implementing  the America Invents  Act of 2011,

wide-ranging patent reform legislation. The United States Supreme  Court has ruled on several patent
cases in recent years, either narrowing the scope of patent protection  available  in certain circumstances
or weakening the rights of patent owners in certain  situations. In addition to increasing uncertainty with
regard to our ability to obtain patents in the  future, this combination of events has  created uncertainty
with respect to the value of patents,  once obtained. Depending on decisions by the U.S. Congress,  the
federal courts, and the U.S. PTO, the  laws and regulations governing  patents could change in
unpredictable ways that would weaken  our ability to obtain  new  patents or to enforce our existing
patents and patents that we might obtain in  the future.

Obtaining and maintaining our patent  protection  depends on compliance with  various procedural, document
submission, fee payment and other requirements imposed by governmental patent agencies, and our  patent
protection could be reduced or eliminated  for non-compliance with these requirements.

The U.S. PTO and various foreign governmental  patent agencies require compliance with  a

number of procedural, documentary,  fee  payment and other provisions  during the  patent  process.  There
are situations in which noncompliance  can result in abandonment or lapse of a patent or patent
application, resulting in partial or complete loss  of patent rights in the  relevant jurisdiction. In such an
event, competitors might be able to enter the  market  earlier than would otherwise have  been the case.

We could become dependent on licensed intellectual property. If we were to lose our  rights  to licensed
intellectual property, we may not be able  to  continue developing or  commercializing bempedoic acid or  other
product candidates, if approved.

In the future, we may enter into license(s)  to  third-party intellectual property that are necessary or

useful to our business. Such license agreement(s) will likely impose various  obligations upon  us, and
our  licensor(s) have or may have the  right  to  terminate the  license  thereunder in the  event of a
material breach or, in some cases, at  will. Future licensor(s) may allege that  we have breached our
license agreement with them or decide  to  terminate  our  license  at  will, and accordingly seek to
terminate our license. If successful, this could result in  our loss of the right  to  use the licensed
intellectual property, which could materially adversely affect our ability  to  develop  and commercialize  a
product  candidate or product, if approved,  as well as  harm our  competitive  business  position  and our
business prospects.

We do not seek to protect our intellectual  property rights in all jurisdictions throughout the world and we  may
not  be able to adequately enforce our intellectual property rights even  in the  jurisdictions  where  we seek
protection.

Filing, prosecuting and defending patents on  product candidates in all countries  and jurisdictions

throughout the world would be prohibitively expensive,  and  our intellectual property  rights in  some
countries outside the United States could be less extensive than those in the United States. In addition,
the laws of some foreign countries do not protect  intellectual property rights to the  same extent as
federal and state laws in the United  States.  Consequently, we may not  be  able to prevent third  parties
from practicing our inventions in all countries outside  the United  States, or from selling or importing
products made using our inventions in and into the United States  or  other jurisdictions. Competitors
may use our technologies in jurisdictions where we have not  obtained patent protection to develop
their own products and further, may  export  otherwise infringing  products to territories  where we have
patent protection, but enforcement is not as strong  as that in the United States. These  products may
compete with our products and our patents  or other intellectual property rights may not be effective or
sufficient to prevent them from competing.

47

Many companies have encountered significant problems in protecting and defending intellectual

property rights in foreign jurisdictions.  The legal  systems of certain countries, particularly certain
developing  countries, do not favor the  enforcement of patents and other intellectual property
protection, particularly those relating to emerging pharmaceuticals,  which could make it difficult for us
to stop the infringement of our patents  or marketing of competing  products in  violation of our
proprietary rights generally. Proceedings to enforce our patent  rights in  foreign jurisdictions could
result in substantial costs and divert  our efforts and attention from other  aspects  of  our  business,  could
put our patents at risk of being invalidated or  interpreted narrowly, could put our  patent  applications
at risk of  not issuing and could provoke third  parties to assert claims against us. We may not prevail in
any lawsuits that we initiate and the damages or other remedies awarded, if  any, may  not  be
commercially meaningful. Accordingly,  our efforts to enforce our intellectual property rights  around the
world may be inadequate to obtain a  significant commercial advantage from  the intellectual  property
that we develop or license.

We may  be subject to damages resulting from claims that we or our employees have wrongfully used or
disclosed alleged trade secrets of their former employers.

Our employees have been previously employed at other biotechnology or pharmaceutical
companies, including our competitors or  potential competitors. Although we are not aware of any
claims currently pending against us, we may  be  subject to claims that these  employees or we have
inadvertently or otherwise used or disclosed trade secrets or other proprietary information  of the
former employers of our employees. Litigation may be necessary  to  defend against these claims. Even if
we are successful in defending against  these  claims,  litigation could result in substantial costs  and be a
distraction to management. If we fail  in defending such claims,  in addition to paying money  claims,  we
may lose valuable intellectual property rights or  personnel. A loss of key personnel or their work
product  could hamper or prevent our  ability to commercialize bempedoic acid, which would materially
adversely affect our commercial development  efforts.

Risks Related to our Dependence on  Third Parties

We will be unable to directly control all aspects of  our clinical studies due to our  reliance  on CROs and other
third parties that assist us in conducting clinical studies.

We relied on CROs in our prior clinical studies,  and  will continue to rely on CROs to conduct our

ongoing Phase 3 clinical studies and  CVOT for  bempedoic acid, as well  as any clinical studies we may
undertake to develop BA + EZ. As  a  result,  we  will have less direct control over  the conduct,  timing
and  completion of these clinical studies  and  the management of data  developed  through the clinical
studies than would be the case if we were  relying entirely upon  our own staff.  Communicating with
outside parties can also be challenging, potentially leading to mistakes  as well  as difficulties in
coordinating activities. Outside parties may:

• have staffing difficulties;

• fail to comply with contractual obligations;

• experience regulatory compliance issues;

• undergo changes in priorities or become  financially distressed;  or

• form relationships with other entities, some of which may be our competitors.

These factors may materially adversely affect the willingness or ability  of third parties to conduct

our clinical studies and may subject us to unexpected cost increases  that are beyond our control.

Moreover, the FDA requires us to comply  with standards, commonly referred to as Good Clinical
Practices, for conducting, recording, and reporting the results  of  clinical  studies to assure that data  and

48

reported results are credible and accurate and that the rights,  integrity and confidentiality  of  clinical
study participants are protected. Our reliance on third  parties  that we do not control  does not relieve
us of these responsibilities and requirements.

Problems with the timeliness or quality  of  the work  of any  CRO may lead  us to seek to terminate

our  relationship with any such CRO  and use an alternative service  provider. Making  this  change  may
be costly and may delay our clinical studies,  and  contractual restrictions may make such  a change
difficult or impossible to effect. If we  must replace any CRO that is  conducting  our clinical studies, our
clinical studies may have to be suspended  until we  find another CRO  that  offers comparable services.
The time that it takes us to find alternative  organizations may cause  a delay  in the commercialization
of bempedoic acid or may cause us to  incur significant expenses to replicate data that may  be  lost.
Although we do not believe that any CRO on  which we may  rely will  offer services that are  not
available elsewhere, it may be difficult  to find a  replacement organization  that  can conduct our clinical
studies in an acceptable manner and at  an acceptable cost.  Any delay in or  inability to complete our
clinical studies could significantly compromise our ability to secure regulatory  approval of bempedoic
acid and preclude our ability to commercialize bempedoic  acid,  thereby limiting  or preventing our
ability to generate revenue from its sales.

We rely completely on third-party suppliers to  manufacture our  clinical drug supplies for bempedoic  acid, and
we intend to rely on third parties to produce commercial  supplies of  bempedoic acid and  preclinical, clinical
and commercial supplies of any future product candidate.

We  do not currently have, nor do we plan to acquire, the  infrastructure or capability to internally

manufacture our clinical drug supply  of  bempedoic acid, or any  future product candidates,  for use in
the conduct of our preclinical studies and clinical studies, and we lack  the internal  resources  and the
capability to manufacture any product  candidates on a clinical or commercial scale. In addition, we
have no control over the production of ezetimibe  for our BA + EZ  product candidate. The facilities
used by our contract manufacturers to manufacture the  active pharmaceutical ingredient and final drug
for bempedoic acid, or any future product candidates, must be approved by the  FDA and  other
comparable foreign regulatory agencies pursuant to inspections  that would be conducted after  we
submit our  NDA or relevant foreign  regulatory submission to the applicable regulatory  agency.

We  do not control the manufacturing process of, and are completely dependent on,  our contract
manufacturers to comply with current Good Manufacturing Practices for manufacture  of  both active
drug substances and finished drug products. If  our contract manufacturers cannot successfully
manufacture material that conforms  to  our specifications and the  strict regulatory requirements of the
FDA or applicable foreign regulatory  agencies,  they will not  be  able to secure  and/or maintain
regulatory approval for their manufacturing facilities. In addition, we have  no direct control over our
contract manufacturers’ ability to maintain adequate quality control, quality assurance and qualified
personnel. Furthermore, all of our contract manufacturers are engaged with other companies  to  supply
and/or manufacture materials or products for such companies,  which exposes our manufacturers to
regulatory risks for the production of  such  materials  and  products. As a result, failure to satisfy the
regulatory requirements for the production  of  those materials and  products  may affect the  regulatory
clearance of our contract manufacturers’ facilities  generally.  If the FDA or a comparable foreign
regulatory agency does not approve these facilities for the manufacture  of  our product candidates  or if
it withdraws its approval in the future, we may need to find alternative manufacturing  facilities,  which
would adversely impact our ability to develop,  obtain regulatory approval  for or  market our product
candidates.

49

If we do not establish successful collaborations,  we may have to alter our development and commercialization
plans for bempedoic acid.

Our drug development programs and commercialization plans for  bempedoic acid will require

substantial additional cash to fund expenses. We  may  develop and  initially commercialize bempedoic
acid in the United States without a partner. However, in order to pursue the broader statin resistant
market in the United States, we may also enter into a  partnership or co-promotion  arrangement with
an established pharmaceutical company  that has a larger  sales force and we may enter into
collaborative arrangements to develop  and commercialize  bempedoic  acid outside  of  the United  States.
We  will face significant competition in seeking appropriate collaborators  and these collaboration
agreements are complex and time-consuming to negotiate. We  may  not  be  able to negotiate
collaborations on acceptable terms, or  at all. If that were to  occur, we may have to curtail the
development or delay commercialization  of bempedoic acid in certain  geographies, reduce the scope of
our  sales or marketing activities, reduce the  scope  of  our  commercialization  plans, 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 outside of the
United States on our own, we may need  to  obtain additional capital, which may not be available to us
on acceptable terms, or at all.

If a collaborative partner terminates or fails to perform  its obligations  under  an agreement with  us, the
commercialization of bempedoic acid could  be delayed or terminated.

We  are not currently party to any collaborative arrangements for the commercialization of

bempedoic  acid or similar arrangements, although we may  pursue such arrangements before any
commercialization of bempedoic acid outside of the United States  or  to  further  commercialize
bempedoic  acid in the broader statin  resistant market in the United States,  if  approved. If  we are
successful in entering into collaborative arrangements for the commercialization of bempedoic acid or
similar arrangements and any of our  collaborative partners does not devote sufficient time and
resources to a collaboration arrangement with us, we  may not realize the potential commercial  benefits
of the arrangement, and our results of  operations may  be  materially adversely affected. In addition, if
any such future collaboration partner were to breach or  terminate its arrangements  with us, the
commercialization of bempedoic acid could be delayed, curtailed or terminated because we  may not
have sufficient financial resources or  capabilities  to  continue  commercialization of bempedoic  acid on
our  own in such locations.

Much of the potential revenue from future collaborations  may consist  of contingent payments, such

as payments for achieving regulatory  milestones or royalties payable on sales of drugs.  The milestone
and royalty revenue that we may receive under these collaborations will  depend  upon our collaborators’
ability to successfully develop, introduce,  market  and  sell new  products. In addition, collaborators  may
decide to enter into arrangements with third parties  to  commercialize  products developed under
collaborations using our technologies,  which could  reduce the milestone and royalty  revenue that we
may receive, if any. Future collaboration partners  may  fail to develop or effectively  commercialize
products using our products or technologies  because they:

• decide not to devote the necessary resources due to internal constraints, such as limited
personnel with the requisite expertise, limited cash resources or specialized equipment
limitations, or the belief that other drug development programs  may have a higher likelihood of
obtaining marketing approval or may potentially  generate  a  greater return  on investment;

• decide to pursue other technologies or develop other product candidates, either on their own or
in collaboration with others, including our competitors,  to treat the  same  diseases targeted by
our  own collaborative programs;

50

• do not have sufficient resources necessary to carry  the product candidate through  clinical

development, marketing approval and  commercialization;  or

• cannot obtain the necessary marketing approvals.

Competition may negatively impact a  partner’s focus on  and commitment  to  bempedoic acid and,
as a result, could delay or otherwise negatively affect the commercialization of bempedoic acid outside
of the United States or in the broader statin  resistant market in the United  States. If future
collaboration partners fail to develop  or  effectively commercialize bempedoic acid  for any of these
reasons, our sales of bempedoic acid,  if  approved, may be limited, which would have a material adverse
effect on our operating results and financial condition.

Risks Related to General Business, Employee Matters and  Managing Growth

We will need to develop and expand our  company, and we  may encounter difficulties  in managing  this
development and expansion, which could  disrupt our operations.

We  expect that we will continue to increase our workforce and  the  scope  of our  operations.  To
manage our anticipated development  and expansion, we  must  continue to implement  and improve  our
managerial, operational and financial systems, expand our  facilities and continue to recruit  and train
additional qualified personnel. Also, our management may need  to  divert a  disproportionate  amount  of
its  attention away from its day-to-day  activities  and devote  a substantial amount of time to managing
these development activities. Due to our limited resources, we may not be able to effectively manage
the expansion of our operations or recruit and train additional qualified  personnel.  This may  result in
weaknesses in our infrastructure; or give rise  to  operational  mistakes, loss of business opportunities,
loss of employees and reduced productivity among remaining  employees. The physical  expansion of our
operations may lead to significant costs  and  may  divert financial resources from  other projects, such as
the development of bempedoic acid. If our management is unable to effectively manage our expected
development and expansion, our expenses  may  increase more than anticipated,  our  ability  to  generate
or increase our revenue could be reduced and we may not  be  able to implement  our business strategy.
Our future financial performance and  our ability to commercialize bempedoic acid,  if approved, and
compete effectively will depend, in part, on our ability  to  effectively manage the future  development
and expansion of our company.

Our future success depends on our ability to retain members  of our senior  management team, and to  attract,
retain and motivate qualified personnel.

We  are highly dependent on members of our senior management team. We have  entered into
employment agreements with these individuals, but  any employee may terminate his or her  employment
with us. Although we do not have any reason to believe that we will  lose the services of these
individuals in the foreseeable future,  the loss  of  the services  of  these individuals might impede the
achievement of our research, development and commercialization objectives. We rely on  consultants
and advisors, including scientific and  clinical advisors,  to  assist us in  formulating  our  development and
commercialization strategy. Our consultants  and advisors may be employed  by  employers other than us
and may have commitments under consulting or advisory contracts  with other entities that may  limit
their availability to us. Recruiting and retaining  qualified scientific personnel and  sales and marketing
personnel will also be critical to our success.  We  may  not be able to attract  and retain these personnel
on acceptable terms given the competition among numerous pharmaceutical and biotechnology
companies for similar personnel. We also experience competition for  the hiring of scientific  personnel
from universities and research institutions.  Failure  to  succeed in  clinical studies may make it more
challenging to recruit and retain qualified scientific personnel.

51

Our company lacks experience commercializing  products, which may have a  material adverse  effect on  our
business.

We  will need to transition from a company with a development focus to a  company capable of

supporting commercial activities. We  may be unsuccessful in making such a  transition.  Our company
has never filed an NDA and has not  yet demonstrated an ability to obtain marketing approval for or
commercialize a product candidate. Therefore, our clinical  development  and regulatory approval
process may involve more inherent risk, take longer,  and cost more than it would if we were  a company
with a more significant operating history and  had  experience obtaining marketing approval for and
commercializing a product candidate.

Our employees may engage in misconduct  or other  improper activities, including violating applicable
regulatory standards and requirements or engaging in insider trading, which could significantly  harm our
business.

We  are exposed to the risk of employee fraud or other misconduct. Misconduct  by  employees
could include intentional failures to comply with the  regulations  of the FDA and applicable non-U.S.
regulators, provide accurate information  to  the FDA and applicable non-U.S. regulators, comply  with
healthcare fraud and abuse laws and regulations in the  United States and  abroad, report  financial
information or data accurately or disclose unauthorized  activities to us. In  particular, sales,  marketing
and business arrangements in the healthcare  industry  are subject to extensive laws and  regulations
intended to prevent fraud, misconduct, kickbacks,  self-dealing and  other abusive practices. These laws
and regulations restrict or prohibit a wide range  of  pricing, discounting,  marketing  and promotion, sales
commission, customer incentive programs and other business arrangements. Employee misconduct
could also involve  the improper use of, including trading on, information obtained in  the course of
clinical studies, which could result in regulatory  sanctions and serious harm to our reputation.  We have
adopted a code of conduct, but it is not  always  possible to  identify and deter employee  misconduct, and
the precautions we take to detect and prevent this activity may be ineffective 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 comply with  these 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 fines or
other sanctions.

In order to satisfy our obligations as a publicly traded company, we may need to hire qualified accounting
and financial personnel with appropriate  public company experience.

As a relatively new public company, we  need to establish  and maintain effective disclosure  and
financial controls and our corporate governance practices that we  adopted in connection with our  initial
public offering. We may need to hire  additional accounting  and financial  personnel with appropriate
public company experience and technical accounting knowledge, and it may be difficult to recruit  and
maintain such personnel. Even if we are able to hire  appropriate personnel, our  existing operating
expenses and operations will be impacted by the direct costs of  their  employment and the indirect
consequences related to the diversion  of management resources from  product development efforts.

Risks Related to our Financial Position  and Capital  Requirements

We have not generated any revenue from bempedoic acid and  may never be profitable.

Our ability to become profitable depends upon  our ability to generate  revenue. To date, we  have

not generated any revenue from our lead  product candidate, bempedoic acid,  and we do not know
when, or if, we will generate any revenue. We do not  expect  to  generate significant revenue  unless  and

52

until we obtain marketing approval of,  and  begin  to  sell, bempedoic acid. Our ability to generate
revenue depends on a number of factors, including, but  not limited to, our ability to:

• successfully complete our CLEAR Outcomes CVOT;

• successfully complete our global pivotal Phase 3 LDL-C  lowering  program;

• initiate and successfully complete all  safety  studies required to obtain  U.S. and foreign marketing
approval for bempedoic acid as a treatment for ‘‘statin intolerant’’ patients for LDL-C lowering
or CV  risk reduction;

• commercialize bempedoic acid, if approved, by  developing a  sales force or entering  into

collaborations with third parties; and

• achieve market acceptance of bempedoic acid in  the medical  community and  with third-party

payors.

Absent our entering into a collaboration  or partnership  agreement, we expect to incur significant

sales and marketing costs as we prepare  to commercialize bempedoic acid. Even  if  we initiate  and
successfully complete our clinical program  of  bempedoic acid and achieve all clinical  endpoints and
bempedoic  acid is approved for commercial sale, and despite expending these costs, bempedoic acid
may not be a commercially successful drug. We may not achieve profitability  soon  after generating
product  sales, if ever. If we are unable  to generate product revenue, we will not become profitable and
may be unable to continue operations  without continued funding.

Raising additional capital may cause dilution to  our  existing  stockholders, restrict our operations or require
us to relinquish rights.

We  may seek additional capital through a combination  of  private and  public  equity offerings, debt

financings, royalty-based financings, collaborations  and strategic and licensing  arrangements. To  the
extent that we raise additional capital  through the sale of common stock or securities convertible or
exchangeable into common stock, your  ownership interest in our company will be diluted. In addition,
the terms of any such securities may include liquidation or other preferences  that  materially adversely
affect your rights as a stockholder. Debt financing, if available,  would increase  our  fixed  payment
obligations. Debt or royalty-based financings may involve agreements that include  covenants limiting or
restricting our ability to take specific  actions, such as incurring  additional debt, making  capital
expenditures or declaring dividends.  If  we raise  additional  funds through collaboration, strategic
partnerships and licensing arrangements  with third  parties,  we may have to relinquish valuable  rights to
bempedoic  acid, our intellectual property,  future revenue streams or grant  licenses  on terms  that  are
not favorable to us.

Our ability to use our net operating loss  carryforwards  may  be subject to  limitation.

At December 31, 2016, we had United States federal net operating loss carryforwards of

approximately $196.4 million and state  net operating loss carryforwards of  approximately  $18.1 million.
Under Sections 382 and 383 of the Internal Revenue Code  of 1986, as amended,  or the Code, if a
corporation undergoes an ‘‘ownership  change,’’ the corporation’s ability to  use its pre-change  net
operating loss carryforwards and other  pre-change tax attributes,  such as research tax credits, to offset
its  post-change income may be limited. In general, an  ‘‘ownership change’’  will occur if there is a
cumulative change in our ownership  by ‘‘5-percent shareholders’’  that exceeds  50 percentage  points
over a rolling three-year period. Similar  rules may apply under state  tax laws. As a result of prior
equity issuances and other transactions in our stock, we have previously experienced ‘‘ownership
changes’’ under section 382 of the Code and comparable state tax laws. We  may also experience
ownership changes in the future as a result of  future transactions in  our stock.  As a  result, if we  earn
net taxable income, our ability to use  our pre-change net operating loss carryforwards or  other

53

pre-change tax attributes to offset United States federal and state taxable income is subject to
limitations.

Complying with public company reporting  and other obligations  may  strain our financial and managerial
resources. Additionally, we are obligated  to  develop and maintain proper and effective internal  control over
financial reporting,  but we may not complete our analysis of  our internal  control over financial  reporting in a
timely manner or these internal controls may not be determined  to  be effective,  either of which may harm
investor confidence in us and the value  of our common stock.

As a public company, we are required to comply with  applicable provisions of the Sarbanes-Oxley

Act of 2002, as well as other rules and  regulations promulgated  by the SEC and the NASDAQ Stock
Market LLC, or NASDAQ, which results in significant initial and  continuing legal, accounting,
administrative and other costs and expenses. The listing  requirements  of The NASDAQ  Global Market
require that we satisfy certain corporate governance requirements relating to director independence,
distributing annual and interim reports,  stockholder meetings, approvals and  voting, soliciting proxies,
conflicts of interest and a code of conduct.  Our  management  and  other personnel need to devote a
substantial amount of time to ensure  that  we comply with  all of these requirements.

We  are subject to Section 404 of the Sarbanes-Oxley  Act  of 2002, or Section 404, and  the related
rules of the SEC that generally require  our  management and  independent registered public accounting
firm to report on the effectiveness of  our  internal  control  over financial reporting. Section 404 requires
an annual management assessment, as  well as an  opinion from  our independent registered  public
accounting firm, on the effectiveness  of  our  internal  control over financial  reporting.

We  are in the costly and challenging process of evaluating and testing our internal controls for the

purpose of providing the reports required by these  rules. We may not be able to complete our
evaluation, testing and any required  remediation in a  timely fashion. During the  course  of  our  review
and testing, we may identify deficiencies and be unable to  remediate them before we must provide the
required reports. Furthermore, if we  have a  material weakness in  our internal control over  financial
reporting, we may not detect errors on a timely basis and our financial statements  may be materially
misstated. We or our independent registered public  accounting  firm may not be able  to  conclude on an
ongoing basis that we have effective internal control over financial reporting,  which could harm our
operating results, cause investors to lose confidence  in our reported financial information  and cause the
trading price of our stock to fall. In addition, we  are required to timely file accurate quarterly and
annual reports with the SEC under the Securities Exchange Act  of  1934, or  the Exchange Act, as
amended. In order to report our results of operations  and financial  statements on  an accurate and
timely basis, we depend on CROs to provide timely and accurate  notice of  their costs to us. Any failure
to report our financial results on an accurate and timely basis could result in sanctions, lawsuits,
delisting of our shares from The NASDAQ Global Market or  other adverse consequences  that  would
materially harm our business.

Risks Related to the Securities Markets and Investment in our  Common Stock

Our principal stockholders and management  own a significant percentage of  our  stock and will  be able to
exert  significant control over matters subject to stockholder approval.

At December 31, 2016, our executive  officers, directors and entities  affiliated with certain  of  our

directors beneficially owned approximately 32.2% of our  outstanding voting  common stock. These
stockholders have the ability to influence us through their  ownership  position.  These stockholders may
be able to determine the outcome of all  matters requiring  stockholder  approval. For  example, these
stockholders may be able to control elections of directors,  amendments of our organizational
documents, or approval of any merger, sale of  assets, or  other major corporate transaction.  This may

54

prevent or discourage unsolicited acquisition proposals or  offers for our common stock that you may
feel are in your best interest as one of our stockholders.

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

At December 31, 2016, certain holders of shares of our common stock held approximately

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

Market volatility may affect our stock price and the value of your investment.

The market price of our common stock may  fluctuate significantly in response to a number of

factors, most of which we cannot control,  including, among others:

• plans for, progress of or results from clinical efficacy or  safety studies of bempedoic  acid;

• guidance from or communications  with the  FDA regarding our  ongoing or  planned clinical

studies  of bempedoic acid;

• the failure of or delay by of the FDA to approve bempedoic acid in  our desired  or expected

target indications or at all;

• announcements  of new products, technologies, commercial relationships, acquisitions  or other

events by us or our competitors;

• the success or failure of other LDL-C lowering therapies;

• regulatory or legal developments in the  United States and other  countries;

• failure of bempedoic acid, if approved, to achieve commercial success;

• fluctuations in stock market prices  and trading volumes of  similar companies;

• general market conditions and overall fluctuations  in U.S. equity  markets;

• variations in our quarterly operating  results;

• changes in our financial guidance or securities analysts’ estimates of  our financial performance;

• changes in accounting principles;

• our ability to raise additional capital  and  the terms on which we can raise it;

• sales  of large blocks of our common  stock,  including sales by  our executive officers,  directors

and significant stockholders;

• additions or departures of key personnel;

• discussion of us or our stock price  by the press and by online investor communities; and

• other risks and uncertainties described in these risk factors.

As a result, you may not be able to sell your shares of common stock at or above  the price at

which  you purchase them.

55

We may  be at an increased risk of securities class action litigation.

Historically, securities class action litigation has often been brought against a company following a
decline  in the market price of its securities. This  risk  is especially  relevant  for us  because biotechnology
and pharmaceutical companies have  experienced significant stock price  volatility in recent years. For
example, as described further in Part  I, Item 3—Legal Proceedings, a purported securities class  action
lawsuit was filed in January 2016 naming us and certain of  our officers as  defendants. In  December
2016, the court granted our motion to dismiss with  prejudice and  entered judgement  in our favor. In
January 2017, the plaintiffs in this lawsuit  filed a  motion to alter  or amend the judgement. Additionally,
in December 2016, a purported derivative action was filed in Delaware against certain  of  our  directors
and officers. Any lawsuit to which we  or our directors  or officers are a  party, with or  without merit,
may result in an unfavorable judgment.  We also  may  decide to settle  lawsuits on  unfavorable terms.
Any such negative outcome could result  in payments  of  substantial damages  or fines, damage to our
reputation or adverse changes to our offerings or  business  practices. Any  of these results  could
adversely affect our business. In addition,  defending  claims is  costly and can impose a significant
burden on our management. This proceeding and any others in which we may  become involved could
result in substantial costs and a diversion of  management’s attention and  resources,  which could harm
our  business.

If securities or industry analysts cease publishing research or reports or publish misleading,  inaccurate  or
unfavorable research about us, our business or  our market, our stock  price and  trading volume could decline.

The trading market for our common stock is  influenced by  the research and  reports that securities

or industry analysts publish about us, our business,  our market or our  competitors.  We  only  recently
started receiving research coverage by  securities and industry analysts. If one  or more of the  industry
analysts who covers us downgrades our  stock or  publishes inaccurate  or  unfavorable research about our
business, or provides more favorable relative  recommendations about our competitors, our stock price
would likely decline. If one or more  of  these  analysts  ceases  coverage of us or  fails to publish reports
on us regularly, demand for our stock  could decrease, which could  cause our stock price  or trading
volume to decline.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us,
even one that may be beneficial to our  stockholders,  more difficult and  may  prevent attempts by our
stockholders to replace or remove our current management.

Provisions in our certificate of incorporation and bylaws may delay or prevent an acquisition of  us
or a change in our management. These provisions include a classified board of  directors, a  prohibition
on actions by written consent of our stockholders and the  ability of our board of directors to issue
preferred stock without stockholder approval. In addition, because  we  are incorporated in Delaware, we
are governed by the provisions of Section  203 of the Delaware  General Corporation Law,  which limits
the ability of stockholders owning in excess  of 15% of our outstanding voting stock to merge  or
combine with us. Although we believe these  provisions collectively provide for an opportunity to obtain
greater value for stockholders by requiring  potential  acquirors to negotiate  with our board  of directors,
they would apply even if an offer rejected  by  our board were considered beneficial by some
stockholders. In addition, these provisions  may  frustrate or  prevent any attempts by our stockholders to
replace or remove our current management by making it  more difficult for stockholders to replace
members of our board of directors, which is responsible for appointing the  members of our
management.

56

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

We  have never declared or paid any cash  dividend  on our common stock and  do not currently
intend to do so in the foreseeable future. We  currently  anticipate that  we will retain  future earnings for
the development, operation and expansion of our business and  do not anticipate declaring or paying
any cash dividends in the foreseeable future. Therefore, the success of  an investment in  shares of our
common stock will depend upon any  future appreciation in  their value. There is no guarantee  that
shares of our common stock will appreciate in value or even maintain the price  at which  you purchased
them. Additionally, our ability to pay  dividends on  our common stock is  limited by restrictions  under
the terms of our Credit Facility with  Oxford Finance  LLC.

Item 1B. Unresolved Staff Comments

None.

Item 2. Properties

Our corporate headquarters are located in  Ann Arbor, Michigan where we lease  and occupy
approximately 7,900 square feet of office  space. We lease and  occupy an  additional 5,500  square  feet of
office space in Ann Arbor, Michigan to support our  clinical  development operations. We  believe our
current facilities will be sufficient to meet our needs until expiration.

Item 3. Legal Proceedings

On January 12, 2016, a purported stockholder  of the Company filed  a putative class action lawsuit
in the United States District Court for the Eastern District of Michigan, against us and  Tim Mayleben,
captioned Kevin L. Dougherty v. Esperion Therapeutics,  Inc., et  al. (No. 16-cv-10089). The lawsuit alleges
that we and Mr. Mayleben violated Sections 10(b) and  20(a) of the Securities Exchange  Act of 1934
and SEC Rule 10b-5 by allegedly failing  to disclose in an August 17, 2015,  public statement that the
FDA would require a cardiovascular outcomes  trial before approving our lead product candidate. The
lawsuit seeks, among other things, compensatory  damages  in connection with an  allegedly inflated stock
price between August 18, 2015, and September 28, 2015, as  well as attorneys’  fees  and costs. On
May 20, 2016, an amended complaint  was filed in the lawsuit.  On July 5,  2016,  we filed a motion to
dismiss the amended complaint. On December 27, 2016,  the court granted  our motion to dismiss with
prejudice and entered judgment in our  favor. On January  24,  2017, the plaintiffs in this lawsuit filed a
motion to alter or amend the judgment.

On December 15, 2016, a purported stockholder of the  Company filed a  derivative lawsuit in  the
Court of Chancery of the State of Delaware  against Tim Mayleben,  Roger Newton, Mary  McGowan,
Nicole Vitullo, Dov Goldstein, Daniel  Janney, Antonio  Gotto Jr., Mark McGovern,  Gilbert Omenn,
Scott  Braunstein, and Patrick Enright.  The Company is  named  as a  nominal defendant.  The  lawsuit
alleges that the defendants breached their fiduciary duties to the Company  when they made or
approved improper statements on August 17, 2015 regarding  our lead product candidate’s path to FDA
approval, and failed to ensure that reliable  systems of internal controls were  in place  at the Company.
The lawsuit seeks, among other things,  any  damages sustained by the Company as a result of the
defendants’ alleged breaches of fiduciary duties, including damages related to the above-referenced
securities class action, an order directing the Company  to  take  all necessary actions to reform  and
improve its corporate governance and internal procedures, restitution from the  defendants, and
attorneys’ fees and costs. In light of,  among other  things, the early stage of the  litigation, we are unable
to predict the outcome of this matter  and  are unable  to  make a meaningful  estimate of the  amount or
range of loss, if any, that could result  from an unfavorable  outcome.

57

In the future, we may become party to  legal matters and claims arising  in the ordinary course of

business, the resolution of which we  do not anticipate would have  a  material adverse impact on our
financial position, results of operations  or cash flows.

Item 7. Management’s Discussion and  Analysis of Financial  Condition and  Results  of Operation

You should read the following discussion and analysis of  our financial condition and results of

operations together with our consolidated  financial statements and related notes appearing elsewhere in this
Annual Report on Form 10-K. In addition to historical  information, this  discussion and  analysis contains
forward-looking statements that involve  risks, uncertainties and assumptions. Our actual results  may differ
materially from those anticipated in these  forward-looking statements as a result  of  certain factors.  We
discuss factors that we believe could cause or contribute to these differences below  and elsewhere  in  this
report, including those set forth under Item 1A. ‘‘Risk Factors’’ and under ‘‘Forward-Looking  Statements’’ in
this Annual Report on Form 10-K.

Overview

Corporate Overview

We  are the lipid management company, a  late-stage pharmaceutical company focused on

developing  and commercializing convenient,  complementary,  cost-effective, once-daily, oral therapies
for the treatment of patients with elevated  LDL-C.  Through scientific and clinical  excellence,  and a
deep understanding of cholesterol biology,  the experienced lipid  management team at  Esperion is
committed to developing new LDL-C  lowering therapies that will make  a  substantial impact on
reducing global cardiovascular disease, or CVD;  the leading cause of death around the  world. With a
targeted mechanism of action, bempedoic acid,  our  lead product  candidate, is  a first-in-class, orally
available, once-daily ACL inhibitor that reduces cholesterol  biosynthesis and  lowers elevated levels of
LDL-C by up-regulating the LDL receptor, but with reduced  potential for muscle-related side  effects.
In addition to bempedoic acid as monotherapy,  we are also  developing bempedoic acid  in a fixed dose
combination with ezetimibe, an approved, non—statin,  oral, LDL-C lowering therapy.

The clinical development program for bempedoic acid  consists of two major components:  1)  the
global  pivotal Phase 3 LDL-C lowering  program  in high CVD  risk patients with hypercholesterolemia
on optimized background lipid-modifying therapy,  including maximally tolerated statins,  and patients
who are only able to tolerate less than the  lowest approved daily starting dose  of  their  statin  and are
considered ‘‘statin intolerant,’’ and 2)  the global CVOT—known  as Cholesterol Lowering via
BEmpedoic Acid, an ACL-inhibiting Regimen (CLEAR) Outcomes, in patients with
hypercholesterolemia and high CVD  risk and who are considered ‘‘statin  intolerant’’. We initiated our
global  Phase 3 clinical development program in January  2016, with  the 52-week global pivotal  Phase 3
long-term safety study and tolerability  (Study 1), and initiated the  three remaining global pivotal
LDL-C lowering efficacy studies in December 2016. We expect  to  report top-line  results from  our
global  Phase 3 program in its entirety by mid-2018, and intend  to  use positive results  from our  Phase 3
program to support our submissions  for an LDL-C lowering indication  in the U.S. and Europe  by  the
first half of 2019. We also initiated the CLEAR  Outcomes CVOT in December 2016,  and intend to use
positive results from this CVOT to support  our  submissions for a CV risk reduction  indication in  the
U.S. and Europe by 2022.

We  were incorporated in Delaware in January 2008, and commenced our operations in April 2008.

Since our inception, we have focused  substantially all of our efforts and  financial resources on
developing  bempedoic acid, for which  we recently  initiated  a  global long-term  safety study in  January
2016. We have funded our operations to date  primarily through proceeds  from sales of preferred stock,
convertible promissory notes and warrants, public offerings of common stock  and the  incurrence  of
indebtedness, and we have incurred losses  in each year since  our inception. We  own the exclusive
worldwide rights to bempedoic acid.

We  have not commenced principal operations and do not have any products approved  for sale. To

date,  we have not generated any revenue. We have  never been  profitable and  our net  losses were
$75.0 million, $49.8 million, and $36.4  million for the years ended December 31,  2016, 2015 and 2014,

62

respectively. Substantially all of our net  losses resulted from costs incurred in connection with research
and development programs, general and administrative costs associated with our operations. We  expect
to incur significant expenses and increasing operating losses for the foreseeable  future. We expect our
expenses to increase in connection with our ongoing activities,  including,  among  others:

• completing the clinical development of bempedoic acid;

• undertaking the clinical development activities for  the fixed dose combination of bempedoic acid

and ezetimibe, or BA+EZ;

• completing the global pivotal Phase 3 LDL-C lowering program and the CLEAR Outcomes

CVOT for bempedoic acid;

• seeking regulatory approval for bempedoic acid;

• commercializing bempedoic acid; and

• operating as a public company.

Accordingly, we will need additional financing  to  support our  continuing operations. We will seek

to fund our operations through public  or  private equity or debt financings  or through other sources,
which  may include collaborations with  third parties. Adequate additional financing may  not  be  available
to us on acceptable terms, or at all. Our failure to raise capital as and when  needed  would have a
material adverse effect on our financial  condition and our  ability to pursue our business strategy  or
continue operations. We will need to generate  significant revenues to achieve profitability, and we  may
never do so.

Product Overview

With a targeted mechanism of action, bempedoic  acid is a  first-in-class, orally available, once-daily

ACL inhibitor that reduces cholesterol  biosynthesis and lowers elevated  levels of LDL-C by
up-regulating the LDL receptor, but with reduced potential for muscle-related side effects.  Bempedoic
acid is being developed for patients with hypercholesterolemia. We  acquired the  rights to bempedoic
acid from Pfizer in 2008. We own the exclusive worldwide  rights to bempedoic acid and we  are not
obligated to make any royalty or milestone payments to Pfizer.

During the year ended December 31,  2016, we  incurred  $36.2  million in  expenses related to the

four  studies in our global pivotal Phase  3 LDL-C lowering program in high  CVD risk patients with
hypercholesterolemia on optimized background lipid-modifying therapy, including maximally tolerated
statins, and patients who are only able  to tolerate less  than the lowest  approved daily starting dose of
their statin and are considered ‘‘statin intolerant,’’ our  CLEAR  Outcomes CVOT in  patients with
hypercholesterolemia and high CVD  risk and who are considered ‘‘statin  intolerant,’’ our  Phase 2  PK/
PD (1002-035) study in patients treated  with  high-dose statin  therapy, our Phase 1 PK (1002-037) study
and other clinical pharmacology studies.

During the year ended December 31,  2015, we  incurred  $12.0  million in  expenses related to our

Phase 2 clinical study in patients with elevated  LDL-C already  receiving  statin  therapy (1002-009), our
Phase 2 exploratory clinical safety study  in patients with  both elevated LDL-C and hypertension
(1002-014), our Phase 3 global long-term safety study in patients with hyperlipidemia whose LDL-C  is
not adequately controlled with low- and moderate-dose statins (1002-040) and other clinical
pharmacology studies.

During the year ended December 31,  2014, we  incurred  $14.5  million in  expenses related to our

Phase 2 clinical study in patients with elevated  LDL-C with or without ‘‘statin intolerance’’ (1002-008),

Financial Operations Overview

Revenue

To date, we have not generated any revenue. In the future, we may never generate  revenue from

the sale of bempedoic acid or other  product candidates.  If we fail to complete the development of
bempedoic  acid or any other product candidates and secure approval from regulatory authorities, our
ability to generate future revenue and our results of operations and financial position will be adversely
affected.

Research and Development Expenses

Since our inception, we have focused  our resources  on our research and development activities,

including conducting nonclinical, preclinical and clinical studies. Our  research  and development
expenses consist primarily of costs incurred in connection with the development  of  bempedoic acid,
which  include:

• expenses incurred under agreements with consultants, contract  research  organizations, or CROs,

and investigative sites that conduct our  preclinical and  clinical studies;

• the cost of acquiring, developing and  manufacturing clinical study materials;

• employee-related expenses, including  salaries, benefits,  stock-based compensation and travel

expenses;

• allocated expenses for rent and maintenance of facilities,  insurance and other supplies; and

• costs related to compliance with regulatory requirements.

We  expense research and development costs  as incurred.  To date, substantially  all  of  our  research

and development work has been related  to  bempedoic acid.  Costs for certain development  activities,
such as clinical studies, are recognized based on  an evaluation of the progress  to  completion  of  specific
tasks using data such as patient enrollment,  clinical site  activations or information  provided to us  by
our  vendors. Our direct research and development  expenses  consist principally  of external costs,  such as
fees paid to investigators, consultants,  central laboratories and CROs in connection  with our clinical
studies.  We do not allocate acquiring and manufacturing clinical study materials, salaries,  stock-based
compensation, employee benefits or other indirect costs related to our research and development
function to specific programs.

Our research and development expenses  are expected  to  increase in the foreseeable future.  Costs

associated with bempedoic acid will increase as we further its clinical development, including in
connection with the commencement of  our  global pivotal  Phase 3 LDL-C lowering program and our
CLEAR  Outcomes CVOT. We also expect to incur increased research and development  costs as  we
pursue the clinical development of BA + EZ.  We cannot determine with certainty the  duration and
completion costs associated with the ongoing or future clinical studies  of  bempedoic acid.  Also, we
cannot conclude with certainty if, or when, we  will  generate revenue from the commercialization and
sale of bempedoic acid, if ever. We may  never succeed  in obtaining  regulatory approval for  bempedoic
acid. The duration, costs and timing associated with  the development  and  commercialization of
bempedoic  acid will depend on a variety of factors, including uncertainties associated with the results of
our  clinical studies and our ability to  obtain regulatory approval. For example,  if  the FDA  or another
regulatory authority were to require  us to conduct clinical studies beyond those  that  we currently
anticipate will be required for the completion of clinical development or post-commercialization clinical
studies of bempedoic acid, or if we experience significant delays in  enrollment  in any  of our  clinical

64

studies,  we could be required to expend significant additional financial  resources  and time on  the
completion of clinical development or  post-commercialization  clinical  studies of bempedoic  acid.

General and Administrative Expenses

General and administrative expenses primarily consist of salaries  and  related costs  for personnel,

including stock-based compensation, associated with our  executive, accounting  and finance, operational
and other administrative functions. Other general  and administrative  expenses include facility-related
costs, communication expenses and professional  fees  for legal,  patent  prosecution,  protection and
review, consulting and accounting services.

We  anticipate that our general and administrative expenses will increase in the future in

connection with the continued research and development and commercialization  of  bempedoic acid,
increases in our headcount, expansion  of our information  technology infrastructure, and increased
expenses associated with being a public company and complying  with exchange listing  and Securities
and Exchange Commission, or SEC,  requirements, including the  additional complexities and  related
costs of our transition away from being an ‘‘emerging  growth  company’’ under  the rules of the SEC.
These increases will likely include higher legal, compliance,  accounting and investor  and public relations
expenses.

Interest Expense

Interest expense consists primarily of cash  interest costs associated with our credit facility and
non-cash interest costs associated with the  amortization of the related debt discount, deferred  issuance
costs and final payment fee.

Critical Accounting Policies and Significant Judgments and Estimates

Our discussion and analysis of our financial condition and results of  operations is  based on our

financial statements, which have been  prepared  in accordance with generally  accepted accounting
principles in the United States. The preparation of these financial  statements requires us to make
estimates and judgments that affect the reported  amounts  of assets, liabilities and  expenses and the
disclosure of contingent assets and liabilities in  our financial statements. We evaluate  our estimates and
judgments on an ongoing basis, including those  related to accrued expenses and  stock-based
compensation. We base our estimates on historical experience,  known trends and events, contractual
milestones and other various factors that are believed to be reasonable under  the circumstances, the
results of which form the basis for making judgments about the carrying values  of assets and liabilities
that are not readily apparent from other sources. Our actual results may  differ  from these estimates
under different assumptions or conditions.

Our significant accounting policies are described in more detail in Note 2 to our  audited financial

statements appearing elsewhere in this Annual Report on Form  10-K. We  believe the following
accounting policies to be most critical  to understanding  our results  and  financial operations.

Accrued Clinical Development Costs

As part of the process of preparing our financial statements we are required  to  estimate our
accrued expenses. We base our accrued expenses related to clinical studies on  estimates of patient
enrollment and related expenses at clinical investigator sites  as well as  estimates  for the  services
received and efforts expended pursuant  to  contracts  with multiple research institutions and  CROs  that
conduct and manage clinical studies on our behalf. We generally accrue expenses  related to clinical
studies based on contracted amounts  applied  to  the level  of patient enrollment and activity according to
the protocol. If timelines or contracts are modified based upon changes in the clinical study  protocol or
scope of work to be performed, we modify our estimates of  accrued  expenses  accordingly on a

65

prospective basis. If we do not identify costs that we  have begun to incur or  if we underestimate or
overestimate the level of services performed or the costs of these services,  our  actual expenses  could
differ  from our estimates. We do not  anticipate  the future  settlement of existing accruals to differ
materially from our estimates.

Stock-Based Compensation

We  typically grant stock-based compensation to new employees in connection with their
commencement of employment and to  existing employees in connection with annual performance
reviews. We account for all stock-based  compensation payments issued to employees, consultants and
directors using an option-pricing model  for estimating fair  value. Accordingly, stock-based
compensation expense is measured based on the estimated  fair value of the  awards  on the  date of
grant, net of estimated forfeitures. Compensation expense is recognized for  the portion that is
ultimately expected to vest over the period during which  the recipient  renders the required services to
us using the straight-line method. In accordance with authoritative  guidance,  the fair value of
non-employee stock-based awards is  remeasured as the awards vest, and  the resulting  value, if any, is
recognized as expense during the period the related services are rendered.

Significant Factors,  Assumptions and Methodologies Used in Determining  Fair  Value

We  estimate the fair value of our stock-based awards to employees, consultants and directors using

the Black-Scholes option-pricing model. The Black-Scholes model requires the input of subjective
assumptions, including (a) the per share  fair value  of  our common stock, (b) the expected stock price
volatility, (c) the calculation of the expected  term of the  award, (d) the  risk  free interest rate  and
(e) expected dividends. Due to our limited operating history  and a lack of company-specific historical
and implied volatility data, we have based  our  estimate of expected  volatility  on the historical volatility
of a group of similar companies, which  are publicly traded.  When  selecting these  public  companies on
which  we have based our expected stock price volatility, we  selected  companies with comparable
characteristics to us, including enterprise value, risk profiles, position within  the industry, and  with
historical share price information sufficient  to  meet  the expected life of  our  stock-based  awards.  The
historical volatility data was computed  using the  daily closing prices for  the  selected companies’ shares
during the equivalent period of the calculated expected  term  of our  stock-based  awards. We will
continue to apply this process until a sufficient amount of historical information  regarding the volatility
of our own stock price becomes available. We have estimated the expected life of our employee  stock
options using the ‘‘simplified’’ method,  whereby, the expected life equals the arithmetic average  of the
vesting term and the original contractual term of the  option. The risk-free interest  rates  for periods
within the expected life of the option are based on the U.S.  Treasury yield curve in effect during the
period the options were granted. We  have never paid, and do  not  expect to pay,  dividends  in the
foreseeable future.

We  are also required to estimate forfeitures at  the time  of grant, and revise those estimates  in
subsequent periods if actual forfeitures  differ from our estimates. We  use historical data to estimate
pre-vesting option  forfeitures and record stock-based compensation expense  only  for those awards that
are expected to vest. To the extent that  actual  forfeitures  differ from our  estimates, the  difference is
recorded  as a cumulative adjustment  in  the period the estimates  were revised.

Fair Value Estimate

We  are required to estimate the fair value of the common  stock underlying our stock-based awards
when performing the fair value calculations  with the Black-Scholes option-pricing model. All options to
purchase shares of our common stock are intended  to  be  granted  with an exercise price per share no
less  than the fair value per share of our  common stock underlying those options on the date of grant,
based on the information known to us on the  date of  grant.

Recent Accounting Pronouncements

In August 2014, the Financial Accounting Standards  Board, or  FASB, issued Accounting Standards

Update, or ASU, 2014-15 which requires  management of public  companies to evaluate  whether  there
are conditions and events that raise substantial  doubt  about  the entity’s ability to continue as a  going
concern within one year after the financial statements are issued and, if so, to disclose that fact.
Management will be required to make  this evaluation for both  annual  and interim  reporting periods,  if
applicable. Management is also required  to  evaluate and disclose  whether its  plans alleviate that doubt.
The standard is effective for annual periods  ending after December 15, 2016,  and interim periods
within annual periods beginning after  December  15, 2016. The adoption of this standard did  not  have a
material impact on our financial position, results of  operations or related financial statement
disclosures.

In February 2016, the FASB issued ASU 2016-02 which  is intended to improve financial reporting
about leasing transactions. The updated guidance  will  require a lessee to recognize assets and liabilities
for leases with lease terms of more than twelve months.  Consistent  with current  GAAP, the recognition,
measurement and presentation of expenses and cash flows  arising from a  lease by a lessee primarily will
depend  on its classification as a capital or operating  lease. Unlike current GAAP—which requires only
capital leases to be recognized on the balance  sheet—the updated guidance will require both types of
leases to be recognized on the balance  sheet. The standard is  effective  for  public companies for  fiscal
years beginning after December 15, 2018, and interim periods  within those years. Early adoption is
permitted for annual or interim reporting periods  for  which  the financial  statements have not previously
been issued. We do not believe the adoption  of this  standard  will have a material impact on our
financial position, results of operations  or related  financial  statement disclosures.

In March 2016, the FASB issued ASU 2016-09  which includes provisions intended  to  simplify the
various aspects related to how share-based payments are accounted for and presented in the financial
statements. The updated guidance will include income tax consequences on the  income  statement  and
the classification of the tax impact on  the statement of cash flows. Additionally, under  the updated
guidance companies will have to elect whether to account  for forfeitures of share-based payments  by
(1) recognizing forfeitures as they occur or (2) estimating the  number of  awards  expected to be
forfeited  and adjusting the estimate when it is likely to change, as  is currently required.  The standard is
effective for public business entities for fiscal years beginning after December 15, 2016, and  interim
periods within those years. Early adoption  is permitted for annual or  interim reporting periods for
which  the financial statements have not  previously been issued. We do not believe  the adoption of this
standard will have a material impact on  our  financial position, results of  operations  or related financial
statement disclosures.

Research and development expenses

Research and development expenses for the  year  ended December 31, 2016, were $57.9 million
compared to $29.8 million for the year  ended December 31, 2015,  an  increase of $28.1  million. The
increase in research and development expenses was primarily related to the further clinical
development of bempedoic acid, including costs to support the initiation of the three  global pivotal
Phase 3 studies and the CVOT, and further increases in our headcount and stock-based compensation
expense.

General and administrative expenses

General and administrative expenses  for the  year ended December 31, 2016,  were $18.3  million

compared to $20.2 million for the year  ended December 31, 2015,  a  decrease of approximately
$1.9 million. The decrease in general and administrative expenses  was  primarily related to a  reduction
in pre-commercialization activities, partially offset by increases in costs to support  public  company
operations, increases in our headcount, and other  costs to support our growth.

Interest expense

Interest expense for the year ended December  31, 2016,  was  $0.4 million compared to $0.5 million

for the year ended December 31, 2015.  Interest expense  was  related  to  our credit facility with Oxford
Finance LLC.

Other  income, net

Other income, net for the year ended December 31,  2016, was $1.5 million compared to

$0.8 million for the year ended December 31, 2015.  This  increase was primarily related  to  an increase
in interest income earned on our cash, cash  equivalents  and investment  securities.

Research and development expenses

Research and development expenses for the year ended December 31, 2015, were $29.8 million
compared to $25.3 million for the year  ended December 31, 2014,  an  increase of $4.5  million. Research
and development expenses were primarily  related to the further clinical development of bempedoic
acid, including completing our Phase  2 clinical  study in patients with elevated LDL-C already  receiving
statin therapy (1002-009), our Phase  2 exploratory clinical safety study in  patients with elevated LDL-C
and hypertension (1002-014) and our  Phase 3 global long-term safety study  in patients with
hyperlipidemia whose LDL-C is not  adequately  controlled with low-  and moderate-dose statins
(1002-040).

General and administrative expenses

General and administrative expenses for the year ended December 31, 2015,  were $20.2  million

compared to $10.9 million for the year  ended December 31, 2014,  an  increase of $9.3  million. The
increase in general and administrative expenses was primarily attributable to costs associated with
pre-commercialization activities for bempedoic  acid, increases in our headcount, which  includes
increased stock-based compensation  expense for  awards  granted during the period, and  other  costs to
support public company operations and  our growth.

Interest expense

Interest expense for the year ended December 31, 2015, was  $0.5 million compared to $0.3 million

for the year ended December 31, 2014.  Interest expense was  related  to  our credit facility with Oxford
Finance LLC.

Other  income, net

Other income, net for the year ended December 31, 2015,  was approximately $0.8 million
compared to approximately $0.1 million  for  the year  ended  December  31, 2014. This increase was
primarily related to an increase in interest income  earned on our  cash, cash equivalents  and investment
securities.

69

Liquidity and Capital Resources

We  have funded our operations to date primarily through  proceeds from  sales of preferred stock,

convertible promissory notes and warrants,  public  offerings of common stock  and the  incurrence  of
indebtedness. In June 2014, we entered into a loan  and security agreement  (the  credit facility) with
Oxford  Finance LLC whereby we received  net proceeds of $4.9 million from  the issuance of secured
promissory notes under a term loan as  part  of  the facility. In October 2014, we sold 4,887,500  shares of
common stock at a price of $20.00 per  share, less underwriting discounts  and commissions, for  net
proceeds of $91.6 million. In March 2015, we  sold  2,012,500 shares of common  stock  at a  price of
$100.00 per share, less underwriting discounts and  commissions, for net proceeds  of  $190.0 million. To
date,  we have not generated any revenue  and  we anticipate that we will continue to incur losses  for the
foreseeable future.

As of December 31, 2016, our primary sources of liquidity were  our cash  and cash equivalents and

available-for-sale investments, which totaled $38.2 million  and $204.3  million, respectively. We  invest
our  cash equivalents and investments  in  highly  liquid, interest-bearing investment-grade and
government securities to preserve principal.

Operating Activities

We  have incurred,  and expect to continue to incur, significant costs in  the areas of research and

development, regulatory and other clinical study  costs, associated with our development of bempedoic
acid and our operations.

Net cash used in operating activities  totaled $47.7 million  and $38.2  million  for the  years  ended

December 31, 2016 and 2015, respectively. The primary use of our cash  was  to  fund  the development
of bempedoic acid, adjusted for non-cash expenses such as stock-based compensation expense,
depreciation and amortization and changes  in working capital.

Investing Activities

Net cash provided by investing activities of $10.1  million for the year  ended December  31, 2016,

consisted primarily of proceeds from  maturities of highly  liquid, interest  bearing investment-grade  and
government securities. Net cash used  in  investing activities of $160.1  million for the year ended
December 31, 2015, consisted primarily  of  purchases  of highly liquid,  interest bearing investment-grade
and government securities.

Financing Activities

Net cash used in financing activities of $1.6  million  for the  year ended December  31, 2016, related
primarily to payments on our credit facility.  Net cash  provided  by financing  activities of $190.5  million

70

for the year ended December 31, 2015,  related  primarily  to the proceeds of our underwritten public
offering of common stock.

Plan of Operations and Funding Requirements

We  expect to continue to incur significant expenses and increasing operating losses for  the
foreseeable future as we progress through the clinical development program for  bempedoic acid. We
estimate that current cash resources are  sufficient to fund  operations into early  2019 and  through the
announcement of top-line results from all global pivotal Phase 3 safety and efficacy studies. We  will
likely need to raise additional capital to continue  to  fund  the  further  development  and
commercialization efforts for bempedoic acid and our operations, including to fund our initial
submissions for an LDL-C lowering indication in  the U.S. and Europe  and  to  complete the CLEAR
Outcomes CVOT. We have based these  estimates on assumptions that may prove to be wrong, and we
may use our available capital resources sooner than we  currently expect. Because of the  numerous  risks
and uncertainties associated with the development and commercialization of bempedoic  acid and  the
extent to which we may enter into collaborations with pharmaceutical  partners regarding the
development and commercialization of bempedoic acid, we  are unable to  estimate the amounts  of
increased capital outlays and operating  expenses associated with  completing the development and
commercialization of bempedoic acid. Our future funding requirements will depend on  many factors,
including, but not limited to:

• our ability to successfully develop and  commercialize bempedoic acid or other  product

candidates;

• the costs, timing and outcomes of our  ongoing and planned  clinical studies of bempedoic  acid;

• the time and cost necessary to obtain  regulatory approvals  for bempedoic  acid, if  at all;

• our ability to establish a sales, marketing  and  distribution infrastructure to commercialize
bempedoic acid or our ability to establish  any future collaboration or commercialization
arrangements on favorable terms, if at all;

• the costs of preparing, filing and prosecuting  patent  applications, maintaining and enforcing  our

intellectual property rights and defending intellectual property-related claims; and

• the implementation of operational and financial  information technology.

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our
cash needs through a combination of equity offerings, debt  financings, collaborations, strategic alliances
and licensing arrangements. We do not  have any committed external source  of  funds. To the  extent that
we raise additional capital through the sale of equity or convertible  debt securities, the ownership
interest of our stockholders will be diluted,  and  the terms of these securities may  include liquidation or
other preferences that adversely affect your rights  as a common stockholder.  Debt financing, if
available, may involve agreements that include covenants limiting or restricting our ability to take
specific  actions, such as incurring additional debt, making capital expenditures or  declaring dividends. If
we raise additional funds through collaborations, strategic  alliances or licensing  arrangements with
pharmaceutical partners or royalty-based financing  arrangements, we may  have to relinquish valuable
rights to our technologies, future revenue streams or  grant licenses on terms that may  not  be  favorable
to us. If we are unable to raise additional  funds  through equity  or debt financings or through
collaborations, strategic alliances or licensing  arrangements or royalty-based financing arrangements
when needed, we may be required to  delay, limit, reduce or terminate  our product development or
future commercialization efforts or grant rights to develop and market bempedoic acid that we  would
otherwise prefer to develop and market ourselves.

Contractual Obligations and Commitments

We  were originally party to a single lease that  covered both office and laboratory space in

Plymouth, Michigan. The Plymouth lease,  as amended  over  time, was scheduled to expire in April 2014.
In February 2014, we signed a new lease to move our principal executive offices  to  Ann Arbor,
Michigan, while still maintaining our  laboratory space  in Plymouth.  The Ann Arbor lease  has a term  of
63 months and provides for fixed monthly rent of approximately $7,900, with monthly rent increasing
every 12 months, and also provides for  certain rent adjustments to be paid as determined by the
landlord. In May 2014, we amended the  Plymouth  lease to (i) extend the expiration date from April
2014, to April 2017, (ii) adjust the rentable  space to 3,045  square feet, (iii) adjust our proportionate
share of the landlord’s expenses and  taxes to 7.40%, (iv)  extend  our option to renew for  one  term of
three years through written notice to  the landlord by February 2017, and  (v)  decrease the annual base
rent to $37,000, subject to certain increases  and  adjustments. In August 2015,  we signed  a new  lease to
increase our office space in Ann Arbor,  Michigan to support  our growing  company and clinical
development operations. The second Ann Arbor lease  has a  term of 49 months and provides  for fixed
monthly rent of approximately $7,100, with monthly  rent  increasing every 12  months. In December
2015, we terminated our lease for our laboratory space  in Plymouth,  Michigan, effective retroactively
on October 30, 2015, rather than April  30, 2017,  as originally contemplated in the  Plymouth lease.

In June 2014, we entered into a Credit  Facility which  provided  for initial  borrowings of
$5.0 million and additional borrowings of $15.0 million until March  2015. We received  proceeds of
$4.9 million, net of issuance costs, from  the issuance of secured promissory notes  under a  term loan as
part of the Credit Facility and we have not drawn upon any additional  borrowings. Under the Credit
Facility we are obligated to make monthly,  interest-only  payments  on  any term loans funded until
July 1, 2015, and, thereafter, to pay 36 consecutive, equal  monthly installments of principal and interest
from August 1, 2015, through July 1,  2018. The  term loan outstanding under the Credit Facility bears
interest at an annual rate of 6.40%. In  addition, a final payment equal to 8.0%  of any  amounts  drawn
under the Credit Facility is due upon the earlier  of the maturity date  or  prepayment of the term loans.

Item 7A. Quantitative and Qualitative  Disclosures  about Market  Risk

We  had cash and cash equivalents and available-for-sale investments of  approximately  $38.2 million

and $204.3 million, respectively, at December 31, 2016. The  primary  objectives  of our  investment
activities are to preserve principal, provide liquidity and maximize  income without significantly
increasing risk. Our primary exposure  to market risk relates  to  fluctuations in interest  rates  which are
affected by changes in the general level of U.S. interest rates.  Given the short-term  nature of our cash
equivalents, we believe that a sudden change in market interest rates would not be expected to have a
material impact on our financial condition and/or  results of operation. We do not have  any foreign
currency or other derivative financial  instruments.

We  do not believe that our cash, cash  equivalents  and available-for-sale investments  have

significant risk of default or illiquidity. While we  believe our  cash and cash equivalents  do  not  contain
excessive risk, we cannot provide absolute assurance that in the future our investments will not be
subject to adverse changes in market  value. In addition, we maintain significant amounts of cash and
cash equivalents at one or more financial institutions that are in excess of  federally  insured limits.

We  contract with CROs and investigational sites globally. We are therefore subject  to  fluctuations
in foreign currency rates in connection with  these agreements. We do not hedge our foreign currency
exchange rate risk.

Inflation generally affects us by increasing our cost of  labor and clinical  study costs. We  do  not

believe that inflation has had a material  effect on our results of operations  during  the year ended
December 31, 2016.

The financial statements required to be filed pursuant to this  Item  8 are appended  to  this  report.

An index of those financial statements is  found in Item  15.

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 (1) recorded, processed, summarized, and reported  within the time periods specified in  the
SEC’s rules and forms and (2) accumulated and communicated  to  our management, including  our
President and Chief Executive Officer, who is our principal executive  officer and principal financial
officer, to allow timely decisions regarding required disclosure.

As of December 31, 2016, our management, with the  participation of our  principal  executive

officer and principal financial officer,  evaluated the effectiveness  of our  disclosure controls and
procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities and Exchange Act of
1934). Our management recognizes that  any controls and  procedures, no matter how well designed and
operated, can provide only reasonable assurance of achieving their  objectives, and  management
necessarily applies its judgment in evaluating the cost-benefit  relationship  of  possible  controls and
procedures. Our principal executive officer and principal financial officer has concluded based upon the
evaluation described above that, as of December 31,  2016, our  disclosure  controls and  procedures  were
effective at the reasonable assurance level.

Management’s Report on Internal Control  over  Financial Reporting

Our management is responsible for establishing and  maintaining adequate internal  control over

financial reporting for our company.  Internal control over financial reporting  is defined in
Rule 13a-15(f) or 15d-15(f) promulgated  under the  Exchange  Act  as a process designed by, or  under
the supervision of, the company’s principal executive and  principal financial  officer  and effected  by the
company’s board of preparation of financial  statements  for  external purposes in accordance with GAAP
and directors, management and other  personnel, to provide  reasonable assurance  regarding the
reliability of financial reporting and the includes those policies and procedures  that: (i)  pertain to the
maintenance of records that, in reasonable detail,  accurately and fairly reflect the  transactions and
dispositions of the assets of the company; (ii)  provide reasonable assurance that transactions  are
recorded  as necessary to permit preparation of  financial statements in  accordance with generally
accepted accounting principles, and that receipts  and  expenditures of our  company are being made only
in accordance with authorizations of management  and  directors of the company; and  (iii) provide
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or
disposition of our company’s assets that could  have a material  effect on the financial statements.

Internal control over financial reporting is  designed to provide  reasonable assurance  regarding the

reliability of financial reporting and the preparation of financial statements prepared for external
purposes  in accordance with generally accepted accounting principles. Because of its inherent
limitations, internal control over financial reporting  may not prevent or detect misstatements. Also,
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.

Our management, with the participation of  our principal  executive and principal financial  officer,

assessed the effectiveness of our internal  control  over financial reporting as of  December 31,  2016,
based on criteria for effective internal control over  financial  reporting  established in Internal  Control—
Integrated Framework (2013), issued by the  Committee of Sponsoring  Organizations of the Treadway
Commission (COSO). Based on its assessment,  management  concluded that our  internal control over
financial reporting was effective as of  December 31,  2016, based on  those criteria.

The effectiveness of our internal control over financial reporting as of  December 31,  2016, has
been audited by Ernst & Young LLP,  an independent registered  public accounting firm, as stated in
their report which is included herein.

Changes  in Internal Control over Financial Reporting

There were no changes to our internal control over  financial  reporting  that  occurred during the
period covered by this report that have materially  affected,  or are reasonably  likely to materially affect,
our  internal control over financial reporting.

Report of Independent Registered Public Accounting  Firm

The Board of Directors and Stockholders
Esperion Therapeutics, Inc.

We  have audited Esperion Therapeutics, Inc.’s internal control over  financial reporting  as of
December 31, 2016, based on criteria established in Internal Control—Integrated Framework issued by
the Committee of Sponsoring Organizations of the  Treadway Commission  (2013  framework) (the
COSO criteria). Esperion Therapeutics,  Inc.’s management is  responsible for maintaining effective
internal control over financial reporting, and for  its assessment of  the  effectiveness  of internal control
over financial reporting included in the  accompanying Management’s Report on Internal Control over

74

Financial Reporting. Our responsibility  is to express an  opinion  on the company’s internal  control  over
financial reporting based on our audit.

We  conducted our audit in accordance  with the  standards of  the Public Company Accounting
Oversight Board (United States). Those  standards require that we  plan and perform the audit to obtain
reasonable assurance about whether  effective internal control over financial reporting was maintained
in all material respects. Our audit included obtaining an  understanding  of internal control  over
financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design
and operating effectiveness of internal control based on  the assessed risk, and performing such other
procedures as we considered necessary in the circumstances. We  believe that our audit provides a
reasonable basis for our opinion.

A company’s internal control over financial reporting is a  process designed to provide  reasonable

assurance regarding the reliability of  financial reporting and the preparation  of  financial  statements for
external  purposes in accordance with  generally accepted  accounting  principles. A company’s internal
control over financial reporting includes those policies  and procedures that (1)  pertain to the
maintenance of records that, in reasonable detail,  accurately and fairly reflect the  transactions and
dispositions of the assets of the company; (2)  provide reasonable assurance that transactions  are
recorded  as necessary to permit preparation of  financial statements in  accordance with generally
accepted accounting principles, and that receipts  and  expenditures of the company are being made only
in accordance with authorizations of management  and  directors of the company; and  (3) provide
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or
disposition of the company’s assets that  could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial  reporting may not prevent or

detect misstatements. Also, 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.

In our opinion, Esperion Therapeutics, Inc. maintained, in all material  respects, effective internal

control over financial reporting as of  December  31, 2016, based on the COSO criteria.

We  also have audited, in accordance  with the  standards of the Public Company Accounting

Oversight Board (United States), the  balance  sheets of Esperion  Therapeutics, Inc. as of  December 31,
2016 and 2015, and the related statements of  operations  and comprehensive loss, stockholders’ equity
and cash flows for each of the three years in the period ended December  31, 2016 of Esperion
Therapeutics, Inc. and our report dated  February 22,  2017,  expressed an unqualified opinion  thereon.

Report of Independent Registered Public  Accounting Firm

The Board of Directors and Stockholders
Esperion Therapeutics, Inc.

We  have audited the accompanying balance sheets of Esperion  Therapeutics, Inc. as of
December 31, 2016 and 2015, and the related statements of operations and comprehensive  loss,
stockholders’ equity and cash flows for each  of  the three  years in the period ended December 31, 2016.
These financial statements are the responsibility of the Company’s management. Our  responsibility is to
express an opinion on these financial statements based on our  audits.

We  conducted our audits in accordance with the standards  of  the Public Company Accounting
Oversight Board (United States). Those  standards require that we  plan and perform the audit to obtain
reasonable assurance about whether  the  financial  statements are free  of material misstatement.  An
audit includes examining, on a test basis, evidence  supporting the amounts and disclosures  in the
financial statements. An audit also includes assessing the accounting  principles used  and significant
estimates made by management, as well as  evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable  basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects,
the financial position of Esperion Therapeutics,  Inc. at December 31, 2016 and 2015, and the results of
its  operations and its cash flows for each of the three years  in the  period ended  December 31, 2016, in
conformity with U.S. generally accepted  accounting  principles.

We  also have audited, in accordance with the standards of  the Public Company Accounting

Oversight Board (United States), Esperion Therapeutics, Inc.’s internal control  over financial reporting
as of  December 31, 2016, based on criteria established in  Internal  Control—Integrated  Framework
issued by the Committee of Sponsoring  Organizations of the Treadway  Commission (2013 framework)
and our report dated February 22, 2017, expressed an unqualified opinion  thereon.

Notes to the Financial Statements

1. The Company and Basis of Presentation

The Company is the lipid management  company, a late-stage pharmaceutical company focused on
developing  and commercializing convenient, complementary,  cost-effective, once-daily oral therapies for
the treatment of patients with elevated LDL-C. Through scientific and  clinical excellence, and a deep
understanding of cholesterol biology, the experienced  lipid management team at Esperion is committed
to developing new LDL-C lowering therapies that will make a substantial impact on  reducing  global
cardiovascular disease (‘‘CVD’’); the  leading cause of death around the  world. With a targeted
mechanism of action, bempedoic acid, the Company’s  lead product  candidate,  is a first-in-class, orally
available, once-daily ATP-citrate lyase (‘‘ACL’’) inhibitor that reduces  cholesterol biosynthesis and
lowers elevated levels of LDL-C by up-regulating  the LDL receptor,  but with  reduced  potential for
muscle-related side effects. In addition to bempedoic  acid as monotherapy, the Company is also
developing  bempedoic acid in a fixed dose  combination with ezetimibe,  an approved, non—statin, oral,
LDL-C lowering therapy.

The clinical development program for  bempedoic acid consists of two major components:  1)  the
global  pivotal Phase 3 LDL-C lowering  program in high CVD  risk patients with hypercholesterolemia
on optimized background lipid-modifying therapy, including maximally tolerated statins,  and patients
who are only able to tolerate less than the lowest approved daily starting dose  of  their  statin  and are
considered ‘‘statin intolerant,’’ and 2)  the global CVOT—known  as Cholesterol Lowering via
BEmpedoic Acid, an ACL-inhibiting Regimen (CLEAR) Outcomes, in patients with
hypercholesterolemia and high CVD  risk and who are considered ‘‘statin intolerant’’. The Company
initiated the global Phase 3 clinical development program  in  January 2016, with the 52-week global
pivotal Phase 3 long-term safety study (Study  1), and  initiated the three remaining global pivotal
LDL-C lowering efficacy studies in December  2016. The Company expects to report top-line  results
from the global Phase 3 program in its  entirety by mid-2018,  and intends to use the Phase 3 program to
support the submission for an LDL-C lowering indication in the U.S. and Europe by the first half of
2019. The Company also initiated the CLEAR  Outcomes CVOT in  December 2016, and intends to use
positive results from this CVOT to support  the submissions  for a CV risk reduction  indication in the
U.S. and Europe by 2022.

The Company’s primary activities since incorporation have been conducting  research  and
development activities, including nonclinical, preclinical and clinical testing, performing business and
financial planning, recruiting personnel,  and  raising capital.  Accordingly, the Company has not
commenced principal operations and  is subject to risks and uncertainties which include the need to
research, develop, and clinically test  potential therapeutic products;  obtain regulatory approvals for  its
products and commercialize them, if  approved; expand its management and scientific  staff; and finance
its  operations with an ultimate goal of  achieving profitable operations.

The Company has sustained operating  losses since inception and expects  such losses to continue

over the foreseeable future. Management plans to continue to fund operations through public or
private  equity or debt financings or through  other  sources, which may include collaborations with third
parties. If adequate funds are not available,  the Company may not be able to continue the development
of its current or future product candidates, or  to  commercialize its  current or future product
candidates, if approved.

common stock, including 262,500 shares sold pursuant to the full exercise  of an over-allotment  option
granted to the underwriters. All the shares were  offered by the Company  at a price to the public of
$100.00 per share. The aggregate net  proceeds received by the Company from the offering were
$190.0 million, net of underwriting discounts and commissions and expenses payable  by  the Company.

2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements  in  accordance with generally accepted accounting

principles in the United States requires  management to make estimates and assumptions that affect the
reported amounts of assets, liabilities,  expenses and related disclosures. Actual  results could differ from
those estimates.

Cash and Cash Equivalents

The Company invests its excess cash in bank deposits,  money market accounts, and short-term
investments. The Company considers all  highly liquid investments with an original maturity of 90  days
or less  at the time of purchase to be  cash  equivalents. Cash equivalents are  reported at fair value.

Investments

Investments are considered to be available-for-sale and are  carried  at fair  value. Unrealized gains

and losses, if any, are reported as a separate  component  of stockholders’ equity. The cost of
investments classified as available-for-sale are adjusted  for the amortization of  premiums and accretion
of discounts to maturity and recorded in  other income, net. Realized gains and losses, if any, are
determined using the specific identification method  and recorded in other income, net.  Investments
with original maturities beyond 90 days  at  the date of purchase and which mature  at, or less than
twelve months from, the balance sheet  date are classified  as  current. Investments with a maturity
beyond twelve months from the balance sheet date  are classified as long-term.

Concentration of Credit Risk

Cash, cash equivalents, and marketable securities consist  of  financial instruments that potentially

subject the Company to concentrations of  credit risk. The Company has established  guidelines for
investment of its excess cash and believes the guidelines  maintain safety and liquidity through
diversification of counterparties and maturities.

Notes to the Financial Statements (Continued)

2. Summary of Significant Accounting Policies (Continued)

Segment Information

The Company views its operations and manages its business in one  operating segment, which is the

business of researching, developing and commercializing  therapies for the  treatment of patients with
elevated  LDL-C.

Fair  Value of Financial Instruments

The Company’s cash, cash equivalents and investments  are carried at fair value. Financial
instruments, including other prepaid and  current assets, accounts payable and  accrued liabilities are
carried at cost, which approximates fair  value. Debt is carried at amortized cost, which approximates
fair value.

Property and Equipment, Net

Property and equipment are recorded at cost, less accumulated depreciation. Depreciation  is

provided using the straight-line method over the estimated useful lives of the respective  assets,
generally three to ten years. Leasehold  improvements are amortized over the lesser of  the lease term
or the estimated useful lives of the related assets.

Impairment of Long-Lived Assets

The Company reviews long-lived assets, including property and  equipment,  for impairment
whenever events or changes in business circumstances  indicate that the carrying amount of the assets
may not be fully recoverable. An impairment loss would be recognized when estimated undiscounted
future cash flows expected to result from the use of the asset and its  eventual disposition are less than
its  carrying amount. The impairment loss, if  recognized,  would be based  on the excess  of the carrying
value of the impaired asset over its respective  fair value.  No impairment losses  have been recorded
through December 31, 2016.

Research and Development

Research and development expenses consist of costs incurred  to  further the  Company’s research

and development activities and include  salaries and related benefits,  costs associated with clinical
activities, nonclinical activities, regulatory activities, manufacturing activities to support clinical
activities, research-related overhead expenses and fees paid to external service providers that conduct
certain research and development, clinical, and manufacturing activities on behalf of the  Company.
Research and development costs are expensed as  incurred.

Accrued Clinical Development Costs

Outside research costs are a component of research and development expense. These  expenses
include fees paid to clinical research  organizations and other service  providers  that  conduct certain
clinical and product development activities  on  behalf  of  the Company. Depending upon the timing of
payments to the service providers, the  Company recognizes prepaid expenses or accrued expenses
related to these costs. These accrued  or  prepaid expenses are based  on management’s estimates of  the
work performed under service agreements, milestones achieved  and  experience with similar contracts.
The Company monitors each of these  factors and adjusts estimates accordingly.

2. Summary of Significant Accounting Policies (Continued)

Income Taxes

The Company utilizes the liability method of  accounting for income taxes as  required by ASC 740,

Income Taxes. Under this method, deferred tax assets  and  liabilities are  determined based on
differences between financial reporting  and the tax basis  of  assets and liabilities and are measured
using enacted tax rates and laws that will  be  in  effect when the differences are expected to reverse. The
Company has incurred operating losses  since inception. Accordingly, it is not more likely than not that
the Company will realize deferred tax  assets and as such, it has recorded a  full valuation  allowance.

Warrants

The Company accounts for its warrants issued in connection with its various financing transactions

based upon the characteristics and provisions of the instrument.  Warrants classified as liabilities are
recorded  on the Company’s balance sheet  at their fair value on the date of issuance and are
marked-to-market  on each subsequent reporting period, with the fair value changes recognized in the
statement of operations. Warrants classified as additional-paid-in-capital  are recorded on the
Company’s balance sheet at their fair  value on the date  of  issuance. The warrants are measured using
the Black-Scholes option-pricing model subsequent to the  pricing of the Company’s  IPO and a Monte
Carlo valuation model for previous periods  which are based, in part, upon inputs where there is little
or no market data, requiring the Company to develop its own independent assumptions (see Note  4).

Stock-Based Compensation

The Company accounts for stock-based compensation in accordance with the provisions of ASC

718, Compensation—Stock Compensation.  Accordingly,  compensation costs related to equity
instruments granted are recognized over  the requisite service  periods of the awards on  a straight-line
basis at the grant-date fair value calculated using  a Black-Scholes option-pricing model. Additionally,
under the provisions of ASC 718, the Company  is  required to include an estimate of the number of
awards that will be forfeited in calculating  compensation  costs. Any changes to the estimated forfeiture
rates are accounted for prospectively.  Stock-based compensation arrangements with non-employees are
recognized at the grant-date fair value  and  then re-measured  at each reporting period. Expense  is
recognized during the period the related services  are rendered.

Recent  Accounting Pronouncements

In August 2014, the Financial Accounting Standards  Board  (‘‘FASB’’) issued Accounting Standards

Update (‘‘ASU’’) 2014-15 which requires management of public companies to evaluate whether  there
are conditions and events that raise substantial  doubt  about the entity’s ability to continue as a  going
concern within one year after the financial statements are  issued and, if so, to disclose that fact.
Management will be required to make  this evaluation  for both  annual  and interim  reporting periods, if
applicable. Management is also required  to  evaluate and disclose  whether its plans alleviate that doubt.
The standard is effective for annual periods ending after December 15, 2016, and interim periods
within annual periods beginning after  December  15, 2016.  The adoption of this standard did not have a
material impact on the financial position,  results of operations or  related financial statement
disclosures.

In February 2016, the FASB issued ASU  2016-02 which is intended  to  improve financial reporting
about leasing transactions. The updated guidance will  require a lessee to recognize assets and liabilities

F-10

Esperion Therapeutics, Inc.

Notes to the Financial Statements (Continued)

2. Summary of Significant Accounting Policies (Continued)

for leases with lease terms of more than twelve months.  Consistent  with current GAAP, the recognition,
measurement and presentation of expenses and cash flows arising from a  lease by a lessee primarily will
depend  on its classification as a capital or operating lease. Unlike current GAAP—which requires only
capital leases to be recognized on the balance sheet—the updated guidance will require both types of
leases to be recognized on the balance  sheet.  The standard is  effective for  public companies for fiscal
years beginning after December 15, 2018, and interim periods  within those years. Early adoption is
permitted for annual or interim reporting periods  for which the financial statements have not previously
been issued. The Company does not  believe  the adoption of this standard will have a material impact
on its financial position, results of operations or  related financial statement disclosures.

In March 2016, the FASB issued ASU 2016-09 which includes provisions intended  to  simplify the
various aspects related to how share-based payments are accounted for and presented in the financial
statements. The updated guidance will include income tax consequences on the income statement and
the classification of the tax impact on  the statement of cash flows. Additionally, under the updated
guidance companies will have to elect whether to account  for forfeitures of share-based payments  by
(1) recognizing forfeitures as they occur  or (2) estimating the number of  awards expected to be
forfeited  and adjusting the estimate when it is likely to change, as  is currently required. The standard is
effective for public business entities for fiscal years beginning after December 15, 2016, and  interim
periods within those years. Early adoption is permitted for annual or  interim reporting periods for
which  the financial statements have not  previously been issued. The Company does not believe the
adoption of this standard will have a  material impact  on its financial  position, results of operations or
related financial statement disclosures.

3. Debt

Credit Facility

In June 2014, the Company entered into a loan and security agreement (the ‘‘Credit Facility’’) with

Oxford  Finance LLC which provided for initial borrowings of $5.0 million  under the term loan (the
‘‘Term A Loan’’) and additional borrowings of  $15.0 million (the ‘‘Term B Loan’’) at the Company’s
option, for a maximum of $20.0 million. On June 30,  2014,  the Company received proceeds of
$5.0 million from the issuance of secured promissory  notes under the  Term A Loan. Upon achieving
positive clinical development results in March 2015,  the remaining $15.0 million under the  Term B
Loan became available to be drawn down, at  the Company’s  sole discretion, until March 31,  2015. The
Company did not elect to draw down  the Term B Loan as of March 31, 2015. The  secured promissory
notes issued under the Credit Facility are due on July 1,  2018, and are  collateralized by substantially all
of the Company’s personal property,  other than its  intellectual property.

The Company is obligated to  make monthly, interest-only payments on the Term A Loan  until
July 1, 2015, and, thereafter, to pay 36 consecutive, equal  monthly installments of principal and interest
from August 1, 2015, through July 1,  2018. The Term  A Loan bears interest at an annual  rate of 6.40%.
In addition, a final payment equal to  8.0% of the Term  A Loan  is due upon the earlier of the maturity
date  or prepayment of the term loan.  The  Company is recognizing the final payment  as interest
expense using the effective interest method over the life of the Credit  Facility.

There are no financial covenants associated  to  the Credit  Facility.  However, so long as the Credit

Facility is outstanding, there are negative covenants that  limit or  restrict the Company’s activities, which
include limitations on incurring indebtedness, granting liens, mergers or acquisitions, dispositions of

F-11

Notes to the Financial Statements (Continued)

3. Debt (Continued)

assets, making certain investments, entering into certain transactions  with affiliates, paying dividends or
distributions, encumbering or pledging  interest  in its  intellectual property and certain  other business
transactions. Additionally, the Credit Facility  includes events of default,  the occurrence and
continuation of any of which provides  the lenders the  right to exercise remedies against the Company
and the collateral securing the loans under the Credit Facility, which includes  cash. These events of
default include, among other things,  non-payment of any  amounts due under the Credit Facility,
insolvency, the occurrence of a material adverse event, inaccuracy of representations and warranties,
cross default to material indebtedness and a material judgment  against the  Company. Upon the
occurrence of an event of default, all  obligations under the Credit Facility shall accrue interest at  a rate
equal to the fixed annual rate plus five percentage points.

In connection with the borrowing of the Term A Loan,  the Company issued a warrant to purchase

8,230 shares of common stock at an exercise price of  $15.19  (see Note 4). The warrant resulted in a
debt discount of $0.1 million which is  amortized into  interest expense using the effective interest
method over the life of the Term A Loan. In addition, the Company  incurred debt issuance costs  of
$0.1 million in connection with the borrowing of the  Term A Loan. The debt issuance costs were
capitalized and included in long-term  debt on the  condensed balance sheet at the inception of  the Term
A Loan, and are amortized to interest expense using the effective interest method over the same  term.
As of December 31, 2016, the remaining  unamortized discount and debt  issuance  costs associated  with
the debt were less than $0.1 million and less  than $0.1  million, respectively.

Estimated future principal payments due  under  the Credit Facility are as  follows:

$2,758

During the years ended December 31, 2016  and  2015, the Company recognized $0.4 million  and

$0.5 million of interest expense and made cash interest  payments of $0.2 million  and $0.3 million
related to the Credit Facility, respectively.

4. Warrants

In connection with the Credit Facility entered into in June 2014, the  Company issued a  warrant to

purchase 8,230 shares of common stock at an exercise  price of $15.19. The  warrant will terminate on
the earlier of June 30, 2019, and the closing of  a merger or consolidation  transaction in which  the
Company is not the surviving entity.  The warrant was recorded  at fair value of  $0.1 million to
additional-paid-in-capital in accordance  with ASC 815-10 based upon the  allocation of the debt
proceeds. The Company estimated the  fair  value of the warrant using a  Black-Scholes  option-pricing
model, which is based, in part, upon  subjective assumptions including but not limited to stock  price
volatility, the expected life of the warrant, the risk-free interest rate and  the fair  value of the  common
stock underlying the warrant. The Company estimates the volatility  of  its  stock based on  public
company peer group historical volatility that is in  line with the expected remaining life of the warrant.
The risk-free interest rate is based on the U.S. Treasury  zero-coupon bond for a maturity similar  to the

F-12

Notes to the Financial Statements (Continued)

4. Warrants (Continued)

expected remaining life of the warrant.  The expected  remaining  life of the warrant is assumed to be
equivalent to its remaining contractual term.

Upon the closing of the Company’s IPO, all  warrants exercisable for  1,940,000 shares  of Series A

preferred stock, at an exercise price of $1.00  per  share (unadjusted for stock splits), were  automatically
converted into warrants exercisable for 277,690 shares of common stock, at  an exercise price of $6.99
per  share. As a result, the Company  concluded the warrants outstanding no longer met the criteria to
be classified as liabilities and were reclassified to additional paid-in capital at fair value on the date of
reclassification. During the year ended  December 31, 2015, 29,330 warrants were net exercised for
25,445 shares of the Company’s common stock. The  remaining 248,360  warrants outstanding as of
December 31, 2016, expire in February  2018.

As of December 31, 2016, the Company had warrants outstanding that were exercisable for  a total

of 256,590 shares of common stock at  a  weighted-average exercise price of $7.25  per  share.

5. Commitments and Contingencies

In February 2014, the Company entered  into  an operating  lease agreement for its principal

executive offices located in Ann Arbor,  Michigan commencing in April 2014, with a term of  63 months.
The Company’s lease provides for fixed monthly rent  for the term of the  lease, with monthly rent
increasing every 12 months subsequent to the  first three  months of the lease, and also provides  for
certain rent adjustments to be paid as  determined by the landlord.

In May 2014, the Company entered into the  third amendment to the operating lease agreement for

its  laboratory facility in Plymouth, Michigan. The amendment provides in part that (i) the expiration
date  of  the term of the lease is extended from  April 2014 to April  2017, (ii) the rentable laboratory
space is adjusted to 3,045 square feet, (iii) the Company’s proportionate share of the landlord’s
expenses and taxes is adjusted to 7.40%, (iv)  the Company may exercise its option to renew  the lease
for one term of three years through written notice  to  the landlord  by February 2017,  and (v) the annual
base rent under the lease is decreased  to  $37,000, subject  to increases and adjustments provided in  the
lease. In December 2015, the Company  entered into a termination agreement for its laboratory facility.
Pursuant to the termination, the Plymouth lease  was terminated, effective retroactively on October 30,
2015 (the ‘‘Termination Date’’), rather  than April 30,  2017,  as contemplated by the Plymouth lease,
with the Company  having no further rent obligations to the Landlord  pursuant to the Plymouth lease
after the Termination Date.

In August 2015, the Company entered into an operating lease agreement to increase its office

space and support its clinical development operations located  in Ann Arbor, Michigan, commencing
September 2015, with a term of 49 months. The Company’s  lease provides for fixed monthly rent for
the term of the lease, with monthly rent increasing every 12 months  subsequent  to  the first month of
the lease.

Legal Proceedings

On January 12, 2016, a purported stockholder of the  Company filed  a putative class action lawsuit
in the United States District Court for the Eastern District of Michigan, against the Company and Tim
Mayleben, captioned Kevin L. Dougherty v. Esperion Therapeutics, Inc., et  al. (No. 16-cv-10089). The
lawsuit alleges that the Company and  Mr. Mayleben violated Sections  10(b)  and 20(a) of the Securities
Exchange Act of 1934 and SEC Rule  10b-5  by allegedly failing to disclose in an  August 17, 2015, public
statement that the FDA would require a cardiovascular outcomes trial  before  approving our lead
product  candidate. The lawsuit seeks,  among other things, compensatory damages in connection with an
allegedly inflated stock price between  August 18, 2015,  and September  28, 2015,  as well as attorneys’
fees and costs. On May 20, 2016, an  amended complaint was filed in the  lawsuit  and on July 5, 2016,
the Company filed a motion to dismiss  the amended  complaint. On December 27, 2016, the court
granted the Company’s motion to dismiss with  prejudice  and  entered judgment  in the Company’s favor.
On January 24, 2017, the plaintiffs in  this lawsuit filed  a motion  to  alter or  amend the  judgment.

On December 15, 2016, a purported stockholder  of  the Company filed a  derivative lawsuit in  the
Court of Chancery of the State of Delaware against  Tim Mayleben,  Roger Newton, Mary  McGowan,
Nicole Vitullo, Dov Goldstein, Daniel  Janney, Antonio Gotto Jr., Mark McGovern,  Gilbert Omenn,
Scott  Braunstein, and Patrick Enright.  The Company  is named  as a  nominal defendant.  The  lawsuit
alleges that the defendants breached their fiduciary  duties to the Company  when they made or
approved improper statements on August 17,  2015, regarding  the Company’s lead  product candidate’s
path to FDA approval, and failed to  ensure that reliable systems of  internal controls were in  place at
the Company. The lawsuit seeks, among other things, any damages sustained by the Company  as a
result of the defendants’ alleged breaches  of fiduciary duties, including  damages related to the above-
referenced securities class action, an order directing the  Company to take all necessary actions to
reform and improve its corporate governance and internal procedures, restitution from  the defendants,
and attorneys’ fees and costs. In light of, among  other things, the early  stage of the litigation,  the
Company is unable to predict the outcome of this matter and is  unable to make a meaningful estimate
of the amount or range of loss, if any, that  could  result from an unfavorable outcome.

9. Fair Value Measurements

The Company follows accounting guidance that  emphasizes that fair value  is a market-based

measurement, not an entity-specific measurement.  Fair value is  defined as ‘‘the price that would be
received to sell an asset or paid to transfer a liability in an orderly transaction between market
participants at the measurement date.’’  Fair value measurements are  defined on a three  level hierarchy:

Level 1 inputs: Quoted prices for identical assets or  liabilities in active markets;

Level 2 inputs: Observable inputs other than Level  1 prices, such as quoted market

prices for similar assets or liabilities or other  inputs that  are
observable or can be corroborated by market data; and

Level 3 inputs: Unobservable inputs  that are supported  by little or no market

activity and require the reporting entity to develop  assumptions  that
market participants would use when pricing  the asset  or liability.

The following table presents the Company’s financial assets and liabilities that have been measured

at fair value on a recurring basis:

Fair  Value Measurements on  a Nonrecurring Basis

In addition to items that are measured at fair value  on  a recurring basis, the Company also
measures assets held for sale at the lower of its carrying amount or  fair value on a  nonrecurring  basis.
The Company did not recognize impairment expense and other losses relating to assets held for sale
during the years ended December 31, 2016, 2015,  and  2014.  There are no assets held for sale as  of
December 31, 2016.

10. Stock Compensation

2013 Stock Option and Incentive Plan

In May 2015, the Company’s stockholders  approved  the amended and restated 2013  Stock Option
and Incentive Plan (as amended, the  ‘‘2013 Plan’’) which, among other things, increased the number of
shares of common stock reserved for issuance thereunder. The number of shares of  common stock
available for awards under the 2013 Plan was increased by 923,622  shares from 2,051,378 shares to
2,975,000 shares, plus (i) shares of common stock that  are forfeited, cancelled, held back upon the
exercise or settlement of an award to  cover the  exercise price or tax withholding, reacquired by the
Company prior to vesting, satisfied without the issuance of common stock or otherwise terminated
(other than by exercise) under the 2013 Plan and the Company’s 2008 Incentive Stock Option and
Restricted Stock Plan are added back  to the shares of common stock available for issuance under the
2013 Plan, and (ii) on January 1, 2016,  and  each  January 1, thereafter,  the number  of shares of
common stock reserved and available  for issuance under the 2013 Plan will be cumulatively increased
by 2.5% of the number of shares of common stock  outstanding on the immediately preceding
December 31, or such lesser number of shares of common  stock determined by the compensation
committee.

The 2013 Plan provides for the granting of stock options,  stock appreciation rights, restricted stock

awards, restricted stock units (‘‘RSUs’’),  unrestricted  stock awards,  cash-based awards, performance
share awards and dividend equivalent  rights. The Company incurs stock-based compensation expense
related to stock options and RSUs. The  fair  value of RSUs is determined by the closing market  price
of the Company’s common stock on the date of grant. The fair value of stock options is  calculated
using a Black-Scholes option-pricing model.  The Company accounts for stock-based compensation in
accordance with the provisions of ASC  718, Compensation—Stock Compensation. Accordingly,
compensation costs related to equity instruments granted are recognized over the requisite service
periods of the awards on a straight-line  basis at the  grant-date fair value,  taking  into  account estimated
forfeitures.

2008 Stock Option and Restricted Stock Plan

In April 2008, the Company adopted the 2008 Plan, administered by the Board of Directors  or a

committee appointed by the Board of Directors.  The 2008 Plan provides  for the  granting of stock
options and restricted stock to employees and  nonemployees of the Company.  Options granted under
the 2008 Plan may either be incentive  stock options, restricted stock awards or  nonqualified stock

F-18

Esperion Therapeutics, Inc.

Notes to the Financial Statements (Continued)

10. Stock Compensation (Continued)

options. Stock options and restricted  stock grants may be granted to employees, directors and
consultants.

Stock awards under the 2008 Plan may  be  granted for  up to ten years from the adoption of  the

2008 Plan at prices no less than 100 percent of the  fair value of the shares on the date of the grant as
determined by (i) the closing price of  the Company’s common stock  on any national  exchange, (ii) the
National Association of Securities Dealers  Inc. Automated Quotation  System (‘‘NASDAQ’’), if so
authorized for quotation as a NASDAQ  security, or  (iii) by reasonable application of a reasonable
valuation method. The valuation methods  utilized by the  Company are consistent with  the AICPA
Technical Practice Aid.

Under the 2013 Plan and the 2008 Plan the vesting  of  options granted or restricted  awards given

will be determined individually with each  option grant. Generally, 25 percent of the granted amount
will vest upon the  first anniversary of  the option grant with the remainder vesting ratably on the first
day of each calendar quarter for the  following  three  years. Stock options have  a 10-year life and expire
if not exercised within that period, or if not exercised within 90 days of cessation of providing service to
the Company.

10. Stock Compensation (Continued)

The following table shows the weighted-average  assumptions  used  to  compute the stock-based
compensation costs for the stock options granted  to  employees  and non-employees during the period
from December 31, 2016, to December 31, 2014, using  the Black-Scholes option-pricing model:

The risk-free interest rate assumption  was  based on the United States Treasury’s rates for U.S.

Treasury zero-coupon bonds with maturities similar  to  those of the expected term of the  award  being
valued.  The assumed dividend yield was based on  the Company’s expectation of not paying  dividends  in
the foreseeable future. The weighted-average expected life of the options was calculated  using  the
simplified method as prescribed by the Securities and Exchange Commission Staff Accounting Bulletin
No. 107 (‘‘SAB No. 107’’). This decision was based  on the lack of  relevant historical data due to the
Company’s limited historical experience.  In addition, due to the Company’s  limited historical  data, the
estimated volatility also reflects the application of  SAB  No. 107, incorporating the  historical  volatility  of
comparable companies whose share prices  are publicly available.

The weighted-average grant-date fair values  of stock options  granted during the years ended
December 31, 2016, 2015 and 2014, were $9.78, $38.44  and $10.15,  respectively. During the years ended
December 31, 2016, 2015 and 2014, the Company recognized stock-based compensation expense related
to stock options of $15.6 million, $12.6  million and  $3.7 million, respectively.

As of December 31, 2016, there was approximately $27.3 million  of unrecognized compensation
cost related to unvested options, adjusted for forfeitures, which will  be  recognized over a  weighted-
average period of approximately 2.4 years.

unrecognized stock-based compensation  expense related to unvested RSUs, adjusted for forfeitures,
which  will be recognized over a weighted-average period  of  approximately 2.5  years.

11. Employee Benefit Plan

During 2008, the Company adopted the Esperion Therapeutics, Inc. 401(k) Plan  (the ‘‘401(k)
Plan’’), which qualifies as a deferred salary arrangement under Section 401(k) of the Internal  Revenue
Code. Under the 401(k) Plan, participating  employees  may defer a portion  of their  pretax earnings.
The Company may, at its sole discretion,  contribute for  the benefit of eligible employees.  Company
contributions to the 401(k) Plan during  the years ended  December  31, 2016, 2015 and 2014,  were
$0.2 million, $0.1 million, and $0, respectively.

12. Income Taxes

There was no provision for income taxes for the years ended December 31,  2016, 2015 and 2014,

because the Company has incurred operating  losses  since inception. At  December 31, 2016, the
Company concluded that it is not more  likely  than  not  that the Company will realize the benefit of its
deferred tax assets due to its history of losses. Accordingly, a full valuation allowance has been applied
against the net deferred tax assets.

As of December 31, 2016, 2015 and 2014, the Company had deferred tax assets, before valuation
allowance, of approximately $75.3 million, $50.6  million and $34.2 million, respectively. Realization of
the deferred assets is dependent upon future  taxable income, if any, the amount and  timing of which
are uncertain. Accordingly, the net deferred  tax  assets have been fully offset by a valuation allowance.

As of December 31, 2016, 2015 and 2014, the Company had federal net operating  loss (‘‘NOL’’)

carryforwards of approximately $196.4 million, $137.4 million and $95.1 million, respectively. The
federal NOL carryforwards will expire  at various dates beginning in 2028, if not utilized.  As of
December 31, 2016, 2015 and 2014, the Company had  state NOL carryforwards of approximately
$18.1 million, $15.4 million and $16.6  million, respectively.  The state  NOL carryforwards will  expire at
various dates beginning in 2022, if not  utilized.  The Company has  $4.5 million of NOLs related to
excess tax benefits generated upon the settlement of stock awards that  increased NOL. The Company
cannot record the benefit of these losses in the financial statements until  the losses are  utilized to
reduce its income taxes payable at which  time it will  recognize the tax benefit in equity.

12. Income Taxes (Continued)

If the Company experiences a greater than 50 percentage  point aggregate change in ownership of

certain significant stockholders over a three-year period,  a Section 382 ownership change could be
deemed to have occurred. If a section 382 change occurs, the Company’s future utilization of  the net
operating loss carryforwards and credits  as of the ownership change  will be subject to an annual
limitation under Section 382 of the Internal Revenue Code of 1986, as amended, and  similar state
provisions. Such an annual limitation  may  result in the expiration of net  operating losses before
utilization.

The Company’s reserves related to taxes are  based  on a determination of whether and how much

of a tax benefit taken by the Company in its tax filings or  positions is more likely than not to be
realized following resolution of any potential  contingencies present  related to the  tax benefit. The
Company recognized no material adjustment  for unrecognized income tax benefits. Through
December 31, 2016, the Company had  no  unrecognized tax benefits or related interest and  penalties
accrued.

Significant components of the Company’s deferred tax assets are summarized in the table below:

13. Net Loss Per Common Share

Basic net loss per share is calculated by dividing  net loss by the weighted-average number of
common shares outstanding during the period, without consideration for common stock equivalents.
Diluted net loss per share is computed  by dividing net  loss  by the weighted-average  number of common
stock equivalents outstanding for the  period determined using the treasury-stock  method. For purposes
of this calculation, warrants for common stock,  stock options and unvested restricted stock and RSUs
are considered to be common stock equivalents and are only included in the  calculation of  diluted net
loss per share when their effect is dilutive.
