Letter to shareholders

DEAR SHAREHOLDERS,

As we look back on the year of 2017, we recognize the significant progress that was made in
our development programs and implementation of our corporate strategy, ultimately
culminating in our initial public offering (IPO) on the U.S. NASDAQ exchange in early 2017.

We have a rich pipeline of three New Chemical Entities with our lead asset OBE2109 pursuing
two important indications in Endometriosis and Uterine Fibroids. We continue to make great
progress on all of our assets as noted by the major clinical milestones we reached for all three
development programs in 2017. For our lead asset OBE2109, we completed enrolment of a
phase2b clinical trial for the treatment of endometriosis, our EDELWEISS study, and expect to
report our 12-week primary endpoint data in mid-2018. In Q1 2017 we initiated the Phase 3
program for the Uterine Fibroid indication with the PRIMROSE 1 and 2 studies. For our
second asset, Nolasiban for use in assisted reproduction during in vitro fertilization (IVF)
procedures, we completed the Phase 3 trial recruitment for the IMPLANT2 study. In February
2018, we reported positive results that met the primary endpoint for the IMPLANT2 study.
And finally for our third asset, OBE022 for the treatment of pre-term labor, we initiated a
phase 2a proof of concept trial in late 2017.

We continue to focus on our strategy of becoming a Women’s Health leader by bringing
innovative treatments to physicians and patients that improve upon the efficacy, tolerability
and safety of existing therapeutic alternatives. We are committed to building significant long
term value for our shareholders by remaining focused on achieving our clinical development
milestones with judicious use of our capital. We would like to thank our shareholders,
employees and partners for their unwavering support.

ObsEva S.A. - Annual Report 2017

Business Update

We are a clinical-stage biopharmaceutical company focused on the development and commercialization of novel
therapeutics for serious conditions that compromise a woman’s reproductive health and pregnancy. We are advancing a
pipeline of orally-administered innovative new chemical entities, or NCEs, for the treatment of symptoms associated with
endometriosis and uterine fibroids, improvement of clinical pregnancy and live birth rates in women undergoing IVF and
treatment of preterm labor. We have assembled a strong management team with extensive experience in successfully
developing and commercializing therapeutics in our target market. Our goal is to build the leading women’s reproductive
health and pregnancy company focused on conditions where current treatment options are limited and significant unmet
needs exist.

We were founded in November 2012 by former executives of PregLem SA, or PregLem, a Swiss-based specialty
biopharmaceutical company dedicated to the development and commercialization of innovative drugs for women’s
reproductive medicine. While at PregLem, our senior management team collaborated in the clinical development and
commercialization of several women’s reproductive health therapeutics, including Esmya (ulipristal acetate) for the
treatment of uterine fibroids. PregLem was subsequently acquired by Gedeon Richter in 2010. We believe we will be able
to leverage our senior management team’s long-standing experience working together and with key opinion leaders, patient
groups, payors, reproductive health networks, fertility clinics, obstetricians and gynecologists, or OB/GYNs, nurses and
pharmacists to identify, in-license or acquire, develop and commercialize product candidates. We are merging our passion
for, and extensive experience in, the field of women’s reproductive health and pregnancy, to develop therapeutics that can
help women lead more healthy and fulfilling lives.

We are focused on providing therapeutic solutions for women between the ages of 15 and 49 who suffer from reproductive
health conditions that affect their quality of life, ability to conceive or that complicate pregnancy and the health of
newborns. There are millions of women of reproductive age affected by conditions such as endometriosis, uterine fibroids
and preterm labor, or that require IVF to conceive. We believe the efficacy of current treatment options is limited and
creates a significant unmet need for improved therapeutics for these women. The graphic below depicts the segments and
associated characteristics of the therapeutic market for women’s reproductive health products:

Our portfolio currently consists of three in-licensed NCEs in clinical development for four indications intended to address
areas that we believe present significant unmet medical needs:

•

OBE2109 for the treatment of pain associated with endometriosis and heavy menstrual bleeding associated
with uterine fibroids. We are developing OBE2109 as a novel, oral GnRH receptor antagonist, for the
treatment of pain associated with endometriosis and heavy menstrual bleeding associated with uterine fibroids
in pre-menopausal women. Endometriosis is an often painful disorder in which the tissue that normally lines
the inside of the uterus, called the endometrium, grows outside of the uterus, causing monthly bleeding and
chronic inflammatory reactions inside the abdomen that may result in ovarian cyst formation, scar tissue and

adhesions. The symptoms of endometriosis include significant pain during menstrual periods, chronic pelvic
pain, pain during intercourse, excessive menstrual bleeding and infertility. These symptoms can impact general
physical, mental and social well-being. As of 2014, we believe that approximately 2.5 million women in the
United States were diagnosed and being treated for endometriosis and that the majority of those women
experience significant pain during menstrual periods. Uterine fibroids are common non-cancerous tumors that
develop in the muscular wall of the uterus and have disabling symptoms such as heavy menstrual bleeding.
According to a study published in the American Journal of Obstetrics & Gynecology in 2003, uterine fibroids
affect an estimated 20 to 40% of women over the age of 30 in the United States based on clinical cases and
women who undergo treatment.

In previous Phase 1 and Phase 2 clinical trials, OBE2109 was observed to have a linear PK profile, a
predictable dose-dependent suppression of estradiol and a dose range that was well-tolerated and provided
symptom relief. Aimed at addressing the need of the largest possible population in each indication, our clinical
trials for both of these indications are designed to assess and potentially support the registration of two
regimens of administrations for OBE2109 i.e. (i) a moderate dose of OBE2109 without hormonal add-back
therapy and (ii) a high dose of OBE2109 with hormonal add-back therapy. Add-back therapy consists of co-
administering estrogen and progestin with the GnRH antagonist to compensate for the severe depletion of
estrogen levels and thus prevent the side effects of estrogen over-suppression such as hot flushes and loss of
bone mineral density. We are currently conducting a multiple-dose, placebo-controlled Phase 2b clinical trial of
OBE2109 in patients with endometriosis, which has completed enrollment of approximately 330 patients,
referred to as the EDELWEISS trial. We expect to report primary endpoint results from the first 12-week
evaluation period of the EDELWEISS trial in mid-2018. For the uterine fibroids indication, we have completed
a Phase 1 PK and PD clinical trial to assess two different doses of add-back therapy in patients receiving 100
mg and 200 mg doses of OBE2109 over six weeks. The results of this clinical trial, which were announced in
June 2017, support the add-back therapy dose being utilized in the two randomized, placebo-controlled Phase 3
clinical trials that commenced in the first half of 2017. We refer to these Phase 3 clinical trials of OBE2109 in
patients with heavy menstrual bleeding associated with uterine fibroids as the PRIMROSE clinical trials. The
PRIMROSE clinical trials each have a target enrollment of approximately 500 patients. We expect to report
primary endpoint results following 24 weeks of treatment from the PRIMROSE clinical trials in the second half
of 2019. We believe OBE2109, if approved in either indication, has the potential to be a best-in-class oral
GnRH receptor antagonist based on its favorable PK and PD profiles, and its expected balance between safety
and efficacy. We expect OBE2109 to potentially reduce pain symptoms associated with endometriosis and
heavy menstrual bleeding associated with uterine fibroids, while mitigating bone mineral density loss and other
adverse effects associated with excessive estradiol suppression. Further, we believe that OBE2109 has the
potential to offer flexible dosing alternatives to achieve either partial or full estrogen suppression in individual
patients that can be administered either with or without hormonal add-back therapy. Finally, we believe
OBE2109 has certain advantageous characteristics including the absence of food effect, high bioavailability,
low volume of distribution, no induction of a liver enzyme known as cytochrome P450 3A4, or CYP3A4, and
low PK and PD variability. We believe these characteristics could be key product differentiators compared to
other GnRH receptor antagonists in clinical development.

Nolasiban to improve IVF outcome. We are developing nolasiban, an oral oxytocin receptor antagonist, to
improve clinical pregnancy and live birth rates in women undergoing IVF. Infertility is a disease of the
reproductive system that impairs the body’s ability to perform the basic function of reproduction. IVF helps
women achieve pregnancy through the collection of mature eggs in the ovaries, followed by fertilization and
early embryo development in the laboratory before transfer of the embryos into the womb. In Europe,
approximately 620,000 IVF treatments were performed in 2012, and in the United States, approximately
230,000 IVF treatments were performed in 2015. We believe that nolasiban, if approved, could represent a
compelling option for increasing IVF outcomes. In 2016, we completed our 247-patient, dose-finding, Phase 2
clinical trial of nolasiban in women undergoing IVF. Nolasiban did not reach the primary endpoint of a
statistically significant, dose-proportional, increase in pregnancy rate at six weeks after embryo transfer. In our
post-hoc analysis of the data, which excluded patients with progesterone levels in the top quartile of the patient
pool, we identified a statistically significant dose-proportional increase in pregnancy rate at 10 weeks and live
birth rate. We initiated a European Phase 3 clinical trial, which we refer as IMPLANT2, in women undergoing
IVF in March 2017, announced patient enrollment completion in September 2017, and reported positive topline
results in February 2018.

•

The IMPLANT2 clinical trial demonstrated that Nolasiban significantly increased ongoing pregnancy rate at 10
weeks. The primary endpoint of the clinical trial was met, with an absolute increase in ongoing pregnancy rate
at 10 weeks of 7.1% (placebo 28.5% and nolasiban 35.6%, p = 0.031). This represents a relative increase of
25% in the ongoing pregnancy rate after administration of nolasiban compared to placebo. Nolasiban was very
well tolerated with a safety profile not different from placebo.

OBE022 for the treatment of preterm labor (GA 24-34 weeks). We are developing OBE022, an oral and
selective prostaglandin F2α, or PGF2α, receptor antagonist, as a once daily treatment for preterm labor from 24 to
34 weeks gestational age, or GA. PGF2α is a naturally occurring prostaglandin, or active lipid compound, that
acts to induce labor. Preterm labor, defined as the body commencing the birthing process prior to 37 weeks, is
characterized by uterine contractions, cervical dilation and rupture of the fetal membranes that surround and
protect the fetus during pregnancy. Preterm labor can lead to preterm birth, which is currently the leading
worldwide cause of death of newborn babies. According to the National Center for Health Statistics,
approximately 9.6% of babies in the United States were born preterm in 2014. Over 1 million children under
the age of five died in 2013 worldwide due to preterm birth complications, and many infants who survive
preterm birth are at greater risk for cerebral palsy, delays in development, hearing and vision issues, and often
face a lifetime of disability. The rates of preterm births are rising in almost all countries with reliable data for
preterm birth, and are associated with an immense financial impact to the global healthcare system.

To date, only treatments with limited efficacy or restrictive safety issues are available to treat preterm labor.
In the United States, no drugs are approved for acute treatment of preterm labor and recommended off-label
tocolytic treatments (medications that inhibit labor) include beta-adrenergic receptor agonists, calcium channel
blockers, or NSAIDs, which are used for short-term prolongation of pregnancy (up to 48 hours) to allow for the
administration of antenatal steroids (e.g. betamethasone). Magnesium sulfate, used for fetal neuroprotection
can also be used (up to 48 hours) to inhibit acute preterm labor. Approved tocolytic treatments
in Europe include beta-adrenergic agonists, which carry severe maternal cardiovascular risks, and intravenous
infusions of atosiban (an oxytocin receptor antagonist).

While prostaglandin inhibitors, such as NSAIDs, have been shown to be effective for inhibiting preterm labor,
use of such drugs is limited, due to the threat of serious and sometimes life-threatening side effects in the fetus.
In nonclinical studies, ObsEva has observed that OBE022 markedly reduces spontaneous and induced uterine
contractions in pregnant rats without causing the fetal side effects seen with NSAIDS such as indomethacin.

Through specific antagonism of the PGF2α receptor, OBE022 is designed to control preterm labor by reducing
inflammation, decreasing uterine contractions and preventing cervical changes and fetal membrane ruptures.
Based on its PK profile and efficacy observed in animal models, we believe OBE022 has the potential to
become a first-in-class therapy to suppress preterm labor and delay or avoid preterm birth, without significant
safety concerns for the fetus. In February 2017, we completed a Phase 1 clinical trial assessing the safety,
tolerability and PK profile of OBE022 in healthy post-menopausal female volunteers after single doses of 10
mg to 1,300 mg and multiple doses between 100 mg per day and 1,000 mg per day over 7 consecutive days. In
this trial, OBE022 was observed to have a favorable PK profile, no clinically significant food effect, a
favorable safety profile and to be well-tolerated at doses up to 1,300 mg after single dose administration and up
to 1,000 mg per day after multiple dose administration over 7 days, each of which are above the estimated
clinical effective dose. In March 2017, we completed a set of drug-drug interaction, or DDI, Phase 1 clinical
pharmacology studies investigating the safety, tolerability and PK profile of OBE022 when combined with
magnesium sulfate, atosiban, nifedipine or betamethasone (medications typically used in patients with preterm
labor) in pre-menopausal female volunteers. OBE022 in combination with those drugs was observed to have a
favorable safety profile and to be well-tolerated up to 1,100 mg per day, which was the highest tested dose. In
December, 2017, we announced the initiation of our Phase 2a proof-of-concept trial of OBE022, referred to as
the PROLONG clinical trial. This clinical trial will enroll up to 120 pregnant women presenting with
spontaneous preterm labor at gestational ages between 24 and 34 weeks. We plan to announce initial efficacy
results for the first 60 subjects from PROLONG clinical trial in late 2018.

Business Update

The following table summarizes key information regarding our current product candidates:

We are also evaluating additional indications for our current product candidates as well as opportunities to in-license or
acquire additional product candidates in our therapeutic field.

Our executive team has substantial experience in developing and commercializing pharmaceutical products in this field.
For example, Ernest Loumaye, M.D., Ph.D., OB/GYN, our Chief Executive Officer and co-founder, is a board certified and
academically trained OB/GYN with extensive experience developing therapeutics for women’s health and over 90
publications in peer-reviewed journals. Most recently he was the Chief Executive Officer and Co-Founder of PregLem.
Prior to PregLem, Dr. Loumaye spent nine years as Head of Clinical Development for Reproductive Health at Serono, now
Merck Serono, where he led the worldwide clinical development and contributed to the worldwide registration of Gonal-F,
Luveris and Ovidrel.

In addition, Jean-Pierre Gotteland, Ph.D., our Chief Scientific Officer, and Elke Bestel M.D., our Chief Medical Officer
held the same roles at PregLem where they worked with Dr. Loumaye for six years and successfully in-licensed, developed
and registered a first-in-class product, Esmya (ulipristal acetate), for the treatment of uterine fibroids.

Collectively, our management team has led the clinical development or contributed to the worldwide registration of three
market-leading fertility products at Serono, Gonal-F, Luveris and Ovidrel, as well as other products including Esmya,
Puregon Pen, Implanon, NuvaRing and Evamist. In addition, members of our management team bring pharmaceutical
development, regulatory approval, manufacturing, reimbursement and commercialization experience from other
pharmaceutical and biotechnology companies, including Merck Serono, PregLem, Organon, Allergan, Pierre Fabre,
Novartis Pharma AG, Roche, SmithKline Beecham, Shire, Galderma, Speedel, Evolva SA and Acrux.

We have demonstrated an ability to successfully execute on the first part of our strategy by leveraging our extensive
network in the field of women’s reproductive health and pregnancy to in-license OBE2109 from Kissei and nolasiban and
OBE022 from Merck Serono. Additionally, we have raised $238.1 million in equity financing from inception to
December 31, 2017 from leading healthcare investors.

Our Strengths

We believe our clinical and product development experience in the field of women’s reproductive health and pregnancy
provides us with the following strengths:

•

Strategic focus on diseases in women’s reproductive health and pregnancy that affect growing female
populations with high unmet medical needs and significant commercial potential;

ObsEva S.A. - Annual Report 2017

Business Update

•

Three product candidates with clear mechanisms of action and early evidence of efficacy that have the potential
to progress into and through late-stage clinical trials and potentially commercial stage;

• Management with substantial experience working together and developing and commercializing

pharmaceutical products in the field of women’s reproductive health and pregnancy;

•

Strong industry and key opinion leader relationships in the field of women’s reproductive health and pregnancy
that provide access to potential product in-licensing opportunities and product development experience; and

Support from leading healthcare-focused investors and board members with experience in building and
operating life science companies.

Our Strategy

Our goal is to build the leading women’s reproductive health and pregnancy company focused on conditions where current
treatment options are limited and significant unmet needs exist. The key elements of our strategy include the following:

•

Continue to advance each of our current product candidates in their respective indications.

Develop a targeted commercialization strategy for any approved product candidates. We have obtained
worldwide commercial rights to our lead product candidates, except for certain countries in Asia with respect
to OBE2109. As we move our product candidates through development toward regulatory approval we will
evaluate several options for each product candidate’s commercialization strategy. These options include
building our own internal sales force, entering into a joint marketing partnership with another pharmaceutical
or biotechnology company, or out-licensing the product to another pharmaceutical or biotechnology company.

Pursue additional indications for our current product candidates. We believe each of our current product
candidates have application outside the indications we are currently developing and we plan to pursue
additional indications for our existing product candidates in the near future.

Leverage our international product development experience and extensive network of clinical experts and
pharmaceutical industry executives within women’s reproductive health and pregnancy to in-license or
acquire novel product candidates. We are focused on identifying, and in-licensing or acquiring, additional
clinical-stage product candidates that we believe have the potential to become best-in-class or first-in-class
products for the treatment of serious conditions in women’s reproductive health and pregnancy, if approved.
We intend to focus on product candidates that we believe will be efficient from a capital-management
standpoint, and we are exploring additional needs in our therapeutic field, such as premenstrual syndrome,
fibrocystic breast disease, post-menopausal hot flashes, preeclampsia, dysmenorrhea and menopause-related
auto-immune diseases.

OBE2109: Investigational GnRH Receptor Antagonist for Symptoms Associated with Endometriosis and Uterine
Fibroids

We are developing OBE2109 as an oral GnRH receptor antagonist for the treatment of pain associated with endometriosis
and heavy menstrual bleeding associated with uterine fibroids. We believe OBE2109, if approved, has the potential to be a
best-in-class oral GnRH receptor antagonist based on its favorable PK and PD profiles, and its potential to provide targeted
estradiol suppression to reduce pain symptoms associated with endometriosis and heavy menstrual bleeding associated with
uterine fibroids, while mitigating bone mineral density loss and other adverse effects that are typically associated with
excessive estradiol suppression. We believe that OBE2109 has the potential to offer flexible dosing alternatives to address
the symptoms of the broad patient population, supported by key differentiating product characteristics, including absence of
food effect, high bioavailability, low volume of distribution, no CYP3A4 induction and low PK and PD variability. We
believe these characteristics are key product differentiators compared to other GnRH receptor antagonists in development.

In 2015, we in-licensed OBE2109 from Kissei. Kissei completed three Phase 2a clinical trials in Japan of OBE2109 in
patients with endometriosis, including one double blind placebo-controlled trial with a subgroup of patients diagnosed with
both endometriosis and uterine fibroids.

ObsEva S.A. - Annual Report 2017

Business Update

Aimed at addressing the need of the largest possible population in each indication, our clinical trials for both of these
indications are designed to assess and potentially support the registration of two regimens of administrations for OBE2109
i.e. (i) a moderate dose of OBE2109 without hormonal add-back therapy and (ii) a high dose of OBE2109 with hormonal
add-back therapy. We are currently conducting the 330-patient multiple-dose, placebo-controlled Phase 2b EDELWEISS
clinical trial of OBE2109 in endometriosis patients across 70 sites in the United States and 15 sites in Central and Eastern
Europe. We expect to report primary endpoint results from the first 12-week evaluation period of this trial in mid-2018. We
commenced our two Phase 3 PRIMROSE clinical trials in patients with heavy menstrual bleeding associated with uterine
fibroids in the first half of 2017. The PRIMROSE clinical trials each have a target enrollment of approximately 500 patients
and are being conducted in the United States and in Europe. We expect to report primary endpoint results following 24
weeks of treatment from these Phase 3 clinical trials in the second half of 2019.

Background of Endometriosis and Uterine Fibroids

Endometriosis is a painful disorder in which the endometrium grows outside of the uterus, typically on the lining of the
pelvis, on the ovaries, in the rectovaginal septum, on the bladder, and on the bowels. Endometriosis causes monthly
bleeding and chronic inflammatory reactions in the abdomen that may result in ovarian cyst formation, scar tissue and
adhesions. The symptoms of endometriosis include significant pain during menstrual periods, chronic pelvic pain, pain
during intercourse, excessive menstrual bleeding and infertility which in turn can impact general physical, mental and
social well-being. Often the pain associated with endometriosis is cyclical in nature and reflects the response to
reproductive hormones circulating throughout the body, particularly estrogen. Endometriosis is also one of the leading
causes of infertility. In many instances, endometriosis is only diagnosed when women seek treatment for such infertility.

According to the World Endometriosis Research Foundation, as of 2014, endometriosis affects an estimated one in ten
women during their reproductive years, totaling approximately 176 million women globally between the ages of 15 and 49.
As of 2014, we believe that approximately 2.5 million women in the United States were diagnosed and treated for
endometriosis, and the majority of those women experience significant pain during menstrual periods.

Uterine fibroids are common non-cancerous tumors that develop in the muscular wall of the uterus. Uterine fibroids can
vary in size from a few millimeters to more than 20 centimeters, and in number from a single fibroid to several dozen
fibroids. The main symptoms of uterine fibroids are heavy menstrual bleeding, anemia, abdominal pressure, abdominal
pain, bloating, increased urinary frequency and reproductive dysfunction. Heavy menstrual blood loss is the most frequent
disabling symptom of uterine fibroids. Uterine fibroids also carry an increased risk of pregnancy complications such as
infertility, miscarriage, placental abruption and premature onset of labor.

According to a study published in the American Journal of Obstetrics & Gynecology in 2003, uterine fibroids affect an
estimated 20 to 40% of women over the age of 30 in the United States based on clinical cases and women who undergo
treatment. We believe that more than four million women in the United States are diagnosed and being treated for uterine
fibroids.

The Role of GnRH

The exact causes of endometriosis and uterine fibroids are not currently understood. However, several factors can
contribute to their development and progression, including the rise and fall of hormones, particularly estrogen, mainly in
the form of estradiol. The production of estrogen in the body is regulated by GnRH. GnRH is responsible for stimulating
the synthesis and release of luteinizing hormone, or LH, and follicle stimulating hormone, or FSH, by the pituitary gland.
LH and FSH in turn drive estrogen production through stimulation of the ovaries. Estradiol is the hormone that, among
other effects, causes the endometrium inside the uterus to thicken during the menstrual cycle. Similarly, estradiol has been
determined to promote the growth of endometriosis lesions and uterine fibroids. Various pharmacological treatments
directed at addressing endometriosis and uterine fibroids attempt to regulate the production of estrogen, particularly
estradiol, by controlling the activity of GnRH.

Limitations of Current Therapies for Endometriosis and Uterine Fibroids
Current treatment options for endometriosis and uterine fibroids are either pharmacological or surgical.

ObsEva S.A. - Annual Report 2017

Business Update

Endometriosis

For endometriosis, the treatment selected is based on the severity of pain and the extent of the disease. Endometriosis
treatments aim first to alleviate pain, then to remove or decrease the size and number of endometrial lesions, and possibly
improve fertility. Oral contraceptives, progestins and NSAIDs are generally first-line treatments for women experiencing
pain. Following the failure of first-line therapies, current treatment options are limited to intra-muscular or subcutaneous
GnRH agonist injections, GnRH agonists nasal spray pumps or surgery for the most symptomatic cases.

Surgery can provide short-term relief by excising the endometrial lesions, but often does not prevent the endometrial
lesions from recurring. Surgery requires general anesthesia, and has a risk of scar tissue and adhesion formation in the
pelvis, which could lead to infertility, make pain worse, require additional surgeries or damage other pelvic structures.
Surgical treatments for endometriosis range from laparoscopy to more complex open abdominal surgery. If a woman has
not responded to other medical or surgical treatments, a radical hysterectomy, which is the removal of all or part of the
uterus and the ovaries may be required, resulting in definitive infertility and immediate menopause.

The World Endometriosis Research Foundation through its EndoCost study estimated the aggregate annual cost of
endometriosis to be approximately $80 billion in the United States and approximately $60 billion in Germany, the UK,
France and Italy in 2012 based on current exchange rates.

Uterine Fibroids

For heavy menstrual bleeding associated with uterine fibroids, current treatment options are limited and generally consist of
oral contraceptives, GnRH agonist injections or surgery. Oral contraceptives are generally used as the first-line therapy.
Upon failure of a first-line therapy or contraindication to oral contraceptives, surgical intervention is generally the next
treatment option. Hysterectomy is the most commonly performed surgical treatment option. Other less invasive procedures
include (1) myomectomy, which is a selective removal of the fibroid typically performed by laparoscopy, which usually
preserves fertility, (2) uterine artery embolization, which is a procedure to obstruct the arteries nurturing the fibroid,
performed by arterial catheterization, and (3) if the dominant symptom is bleeding, endometrial ablation, which is a
procedure to remove the inner layer of the uterus performed by thermic or ultrasonic process. According to a study
published in the American Journal of Obstetrics & Gynecology in 2012, approximately 200,000 hysterectomies and 30,000
myomectomies are performed annually for the treatment of uterine fibroids in the United States as of 2003. Hysterectomies
are major surgeries and, according to the National Uterine Fibroids Foundation, approximately 660 women die each year in
the United States from complications from a hysterectomy. Hysterectomies can be both physically and psychologically
damaging, not only resulting in a woman becoming infertile, but they also can be perceived by some women as impairing
their feminine integrity. Surgery also carries a risk of scar tissue and adhesions, which could lead to infertility, make pain
worse, require additional surgeries or damage other pelvic structures.

Treating uterine fibroids is expensive, as surgery constitutes a significant cost burden. Patients who do not undergo surgery
often require medical management, hospitalization and additional outpatient physician visits, which further increase the
annual costs of the disease. According to a systematic review of literature published in the American Journal of
Obstetrics &Gynecology in 2012, direct and indirect costs associated with uterine fibroids were estimated in 2010 to be up
to $34.4 billion annually in the United States.

Mechanism of Action and Limitations of GnRH Agonists

GnRH agonists are a standard pharmaceutical therapy for estrogen dependent conditions such as endometriosis and uterine
fibroids. However, GnRH agonists have significant drawbacks and limitations.

GnRH agonists act by overstimulating the GnRH receptors, which desensitizes pituitary cells, resulting in reduced secretion
of LH and FSH, and severely reduced production of estrogen, a contributing factor to endometriosis and uterine fibroids.
This leads to a state referred to as pseudo-menopause, in which patients experience menopausal symptoms before
ultimately experiencing symptom relief. While GnRH agonists may be effective at treating the symptoms of endometriosis
and uterine fibroids, they can be accompanied with serious drawbacks and limitations including:

•

Excessive suppression of estradiol and related unfavorable side effect profile. Because GnRH agonists cannot
be titrated, they act by excessively suppressing estradiol to a post-menopausal level of less than 20
picogram/milliliter, or pg/ml. Excessive suppression of estrogen can result in multiple side effects before the
patient experiences any relief, including hot flashes and bone mineral density loss. Clinical trials of an

ObsEva S.A. - Annual Report 2017

Business Update

•

approved GnRH agonist demonstrated that patients lose an average of up to 6% of their bone mineral density
after 12 months of GnRH agonist treatment.

Delayed therapeutic effect and initial worsening of symptoms. Since GnRH agonists act by overstimulating
the GnRH receptors, they can cause an initial worsening of symptoms that can last for several weeks.

Administration by injection. Many GnRH agonists such as Lupron (leuprolide acetate) must be injected, which
generally requires the assistance of a doctor or nurse.

Required add-back therapy. To counteract the side effects of the excessive suppression of estrogen, additional
administration of estrogen, referred to as “add-back therapy,” may be recommended after three months of
treatment and is required after six months of treatment. Add-back therapy may result in additional
contraindications and adverse effects.

Variable and unpredictable reversibility of treatment. After stopping treatment with injectable GnRH
agonists, a patient’s ovarian function can take weeks or months to return to normal. This is particularly relevant
and problematic if a patient wishes to conceive after treatment or if treatment is interrupted for lack of
tolerability.

OBE2109’s Mechanism of Action and Solution to GnRH Agonist Drawbacks and Limitations

OBE2109 has been designed to be a GnRH receptor antagonist with oral administration and low PK and PD variability.
OBE2109 binds to and blocks the GnRH receptor in the pituitary gland, which clinical trials suggest, results in a dose-
dependent reduction of LH and FSH production. This reduction in LH and FSH production in turn leads to a reduction of
estrogen levels.

At selected doses, OBE2109 has been observed to maintain estradiol levels in the target range of 20 to 60 pg/ml, which we
believe is the optimal range to relieve symptoms associated with endometriosis and uterine fibroids while mitigating bone
mineral density loss or other adverse effects that can be associated with excessive estradiol suppression.

We believe OBE2109 has the potential to overcome certain drawbacks and limitations of GnRH agonists. The potential
advantages of OBE2109 compared to GnRH agonists include:

•

Fast onset of therapeutic effect. By blocking, as opposed to stimulating, the GnRH receptor, OBE2109 has the
potential to suppress LH and FSH within hours, lowering estradiol levels and reducing pain within days while
potentially avoiding the initial worsening of symptoms which is often associated with GnRH agonist
treatments.

Ease of administration. OBE2109 has the potential to be administered orally once daily, and regardless of food
intake timing. This potential dosing regime is a more convenient treatment option than GnRH agonist
intramuscular or subcutaneous injections.

Optionality for endometriosis and uterine fibroids treatment: stand alone or in combination with add-back
therapy. In contrast to GnRH agonists, for which hormonal add-back therapy may be recommended when
treatment exceeds three months and is required when treatment exceeds six months, we believe that at the 50 to
200 mg doses being tested in our Phase 2b trial, OBE2109 has the potential to be utilized as a stand-alone
treatment for a majority of patients with pain associated with endometriosis by maintaining estradiol levels
between 20 and 60 pg/ml, without the need for add-back therapy to counteract the side effects associated with
full suppression of estradiol. For the treatment of heavy menstrual bleeding associated with uterine fibroids, we
believe that based on our proposed dosing (100-200 mg) some patients may not require add-back therapy,
while others may require add-back therapy, depending on the treatment dosage. Others patients may require
add-back therapy, depending on the treatment dosage required to control symptoms.

Quick reversibility of effect. As a result of OBE2109’s observed half-life of approximately 15 hours, we
believe OBE2109 has the potential for ovarian function to resume within days following the end of treatment.
In contrast, a patient’s ovarian function can take weeks or months to return to normal after stopping treatment
with injectable GnRH agonists.

OBE2109’s Potential Clinical Profile

There are currently no GnRH receptor antagonists approved for the treatment of symptoms associated with endometriosis
or uterine fibroids. We are aware that AbbVie Inc., Myovant Sciences, Inc. and Astellas Pharma Inc. are developing GnRH
receptor antagonists for the treatment of symptoms associated with endometriosis or uterine fibroids.

We believe that OBE2109 has a favorable overall clinical profile as assessed by:

•

Optimal characteristics for consistent PK. OBE2109 has been observed to have a consistent PK profile and
low variability, due to high bioavailability and low volume of distribution. In addition, OBE2109’s half-life
allows for once daily dosing for across indications. We believe these characteristics are important for
optimizing patient compliance and drug exposure.

Flexible dosing alternatives. Based on OBE2109’s consistent PK and PD profile observed in preclinical
studies and clinical trials, we are currently pursuing the development of multiple dosages, which will allow for
partial or full suppression of estrogen. We believe that various levels of estrogen suppression may be required
to successfully treat symptoms in different patients in different indications to account for patient
characteristics, individual response or patient preference.

No systematic need for hormonal add-back therapy. For symptoms associated with both endometriosis and
uterine fibroids, we are developing OBE2109 as a stand-alone treatment (without need for add-back therapy)
and in association with add-back therapy to fulfill the needs of a broad patient population with endometriosis or
uterine fibroids. Relatedly, we do not believe that all patients will have the desire or need for hormonal add-
back therapy, some of whom may have a contraindication or tolerability issue, or simply prefer the
management of endogenous estrogen levels in the clinical setting where bone mineral density loss is not
reduced to the degree that would require such add-back therapy.

Compliance benefit. OBE2109 may have an advantage in patient compliance due to the lack of observed food
effect and the ability to be taken once anytime throughout the day, without the risk of reduced and/or variable
exposure to active drug.

OBE2109 Preclinical and Clinical Development for Pain Associated with Endometriosis

Prior to in-licensing OBE2109, Kissei completed a preclinical program, a Phase 1 clinical trial in healthy female volunteers
of Japanese and European descent and three Phase 2a clinical trials in patients of Japanese descent with endometriosis,
including one trial that included a subgroup of patients with both endometriosis and uterine fibroids. In these trials,
OBE2109 was observed to have a linear PK profile, a predictable dose-dependent suppression of estradiol and a dose range
that was well-tolerated and provided symptom relief. Following our in-license of OBE2109 from Kissei, we submitted an
IND for OBE2109 in May 2016, which was accepted by the FDA. We are currently conducting the multiple-dose, placebo-
controlled Phase 2b EDELWEISS clinical trial of OBE2109 in approximately 330 endometriosis patients in the United
States and Europe. We expect to report initial data from this trial in mid-2018.

Preclinical Studies and Phase 1 Clinical Trial

In preclinical studies, OBE2109 was observed to be a highly potent and selective antagonist of the GnRH receptor. The
preclinical toxicology and safety pharmacology studies did not raise tolerance or safety concerns or potential for DDIs. In
the Phase 1 clinical trial, OBE2109 was observed to have a favorable safety profile and to be well-tolerated up to 400 mg
once daily for seven days. Additionally, OBE2109 had a linear PK profile, a half-life of approximately 15 hours and no
significant differences between women of Japanese and European descent. Moreover, OBE2109 was observed to have a
low volume of distribution, meaning the drug remained in the blood and did not accumulate in fatty tissue, and a dose-
proportional response shown in the Figure 1 below. Furthermore, in the Phase 1 clinical trial, there was no food effect
observed. OBE2109 was observed to induce a dose-dependent decrease in LH and FSH over time, which we believe
correlates with the ability of OBE2109 to control estradiol levels in a dose-dependent manner. Based on the low PK
variability and lack of dose overlap observed in the Phase 1 clinical trial, we believe we will be able to more tightly control
biological response with personalized doses of OBE2109. In addition, in 2016 we completed a Phase 1 trial to assess the
impact of OBE2109 on the potential induction of CYP3A4, which is responsible for most of the metabolism of add-back
therapy. In this trial, we observed no relevant CYP3A4 induction, which we believe suggests that OBE2109 will not
interfere with add-back therapy.

Completed Phase 2a Clinical Trials

Kissei completed three Phase 2a clinical trials of OBE2109 in patients of Japanese descent with endometriosis in 2013 and
2014. Endometriosis was either diagnosed by laparoscopy or by confirmation using ultrasound of ovarian chocolate cysts,
which are a particular type of ovarian cyst associated with endometriosis. Outcomes included changes in pelvic menstrual,
non-menstrual and overall pain scores, analgesic use and hormone levels. The designs of these trials are summarized in the
table below.

ObsEva S.A. - Annual Report 2017

Business Update

Patients reported daily whether they were bleeding, and the level of their pelvic pain using a verbal rating scale from 0 to 4,
with 0 representing no pain and 4 representing unbearable pain even after using a pain relieving drug.

Improvement rate of pelvic pain severity was assessed using the proportion of pain free days during the evaluation period.
Pain free is defined as the absence of pain or slight pain during menstruation and the absence of pain during non-
menstruation. Across all three studies, OBE2109 was observed to rapidly and consistently reduce pelvic pain scores. All
doses were observed to have statistically significant reductions of both menstrual and non-menstrual pelvic pain compared
to placebo.

In the KLH1201 trial, the average severity of pelvic pain during menstruation in the 50 mg and 200 mg treatment groups
was 1.74 +/- 0.62 (mean +/- standard deviation), and 1.42 +/- 0.61, respectively, at baseline, as compared to 0.94 +/- 0.98
and 0.00 +/- 0.00, respectively, at week 8. The average severity of pelvic pain during non-menstruation in the 50 mg and
200 mg treatment groups was 0.25 +/- 0.26 and 0.23 +/- 0.30, respectively, at baseline, as compared to 0.06 +/- 0.12 and
0.12 +/- 0.29, respectively, at week 8. As the trial was not placebo-controlled, no statistical testing was conducted.

In the KLH1203 trial, the average reduction from baseline to week 8 in severity of pelvic pain during menstruation in the
75 mg and 150 mg treatment groups was 1.39 +/- 0.79 and 2.05 +/- 0.90, respectively. The average reduction from baseline
to week 8 in average severity of pelvic pain during non-menstruation in these groups was 0.46 +/- 0.68 and 0.64 +/- 0.70,
respectively. As the trial was not placebo-controlled, no statistical testing was conducted.

In the placebo-controlled KLH1202 trial, there was a statistically significant reduction in pain for each of the 50 mg, 100
mg and 200 mg treatment groups, as compared to placebo at weeks 4, 8 and 12. For menstrual pain, a p-value of less than
0.001 was considered to be statistically significant for all doses. For non-menstrual pain, a p-value equal to 0.003, 0.010
and 0.005 for the 50 mg, 100 mg and 200 mg doses, respectively, was considered to be statistically significant. Patients also
reported that their pelvic pain reduction was maintained four weeks after treatment. The decrease in average severity of
pelvic pain (regardless of presence or absence of menstrual bleeding) and the associated p-value is shown in Figure 3
below.

Figure 3: Average Change in Severity of Pelvic Pain Over Time (Menstrual and Non-menstrual Pain Combined)

In addition, patients reported significant dose-dependent reductions in analgesic use (p<0.001 for all comparisons) and
bleeding days. Estradiol levels were increasingly suppressed in a dose-dependent manner consistently across all three Phase

2a trials, which we believe resulted in the reduction of pelvic pain, analgesic use and bleeding days. Doses of 50 mg and 75
mg were observed to result in median serum estradiol levels in the target range of 20 to 60 pg/ml. Doses of 100 mg, 150 mg
and 200 mg were observed to reduce median estradiol serum levels below 20 pg/ml.

Figure 4: Median Estradiol Levels Over Time

In addition, as shown in Figure 5 below, approximately 40% of the patients receiving 50 mg and 100 mg doses of
OBE2109 were observed to have estradiol levels between 20 to 60 pg/ml at week 12.

Clinical Development Plan—Phase 2b EDELWEISS Clinical Trial in Pain Associated with Endometriosis

We are currently conducting the Phase 2b EDELWEISS clinical trial in patients with endometriosis. We completed
enrollment of approximately 330 patients across 70 sites in the United States and 15 sites in Central and Eastern Europe. In
this double-blind, placebo-controlled trial, we are evaluating four doses of OBE2109: 50 mg, 75 mg, 100 mg and 200 mg,
each with no add-back therapy. Patients will report their pain on a daily basis with an electronic diary and we will analyze
data at 12 weeks and 24 weeks after initial treatment. After the initial 12-week evaluation period, we plan on exploring a
dose titration regimen in an additional trial arm, in which some patients initially dosed with 75 mg will receive an increased
dose of 100 mg, a decreased dose of 50 mg or the same dose of 75 mg for the second 12-week evaluation period, depending
on their respective estradiol levels at 4 and 8 weeks after initial treatment. In addition, after the first 12 weeks, patients
receiving placebo will switch to a 100 mg daily dose.

ObsEva S.A. - Annual Report 2017

Figure 6: Design of Phase 2b EDELWEISS Clinical Trial

Business Update

We believe our current data in endometriosis patients of Japanese descent supports a daily dose of 50 mg or 75 mg of
OBE2109. We believe this daily dose will suppress estradiol within the target range and not result in bone mineral density
loss that requires add-back therapy. We expect slightly higher doses will be required to achieve estradiol suppression within
the target range in patients of American and European descent given a higher average body weight. We plan to confirm this
following the review of the results from the Phase 2b EDELWEISS clinical trial.

Menstrual and non-menstrual pelvic pain will be assessed with a 4-point Verbal Rating Scale, or VRS, and an 11-point
Numeric Rating Scale, or NRS. The primary endpoint of this trial will be the reduction from baseline at week 12 in the
mean overall pelvic VRS pain score. The key secondary endpoint is the bone mineral density after 24 weeks of treatment
assessed with a dual-energy x-ray absorptiometry scan.

After 24 weeks of treatment, patients may choose to continue in an extension trial. In the extension trial, patients will
continue treatment for another 28 weeks at the same dose, with the exception of patients receiving a 200 mg dose, who will
be switched to a 100 mg daily dose. After treatment, all patients will be followed for an additional, 24-week period that will
be treatment free.

We expect to report the primary efficacy results for the 12-week evaluation period in mid-2018, which will allow us to
assess the efficacy of OBE2109 in patients with endometriosis. We expect to receive 24-week treatment data including
bone mineral density safety assessments in the second half of 2018 with longer term follow-up extending into 2019.
Assuming the results of the trial are favorable, we plan to request an end-of-Phase 2 meeting with the FDA in the fourth
quarter of 2018 to determine the design of our Phase 3 program for pain associated with endometriosis.

OBE2109 Clinical Development for Heavy Menstrual Bleeding Associated with Uterine Fibroids

We are developing OBE2109 for reduction of heavy menstrual bleeding associated with uterine fibroids in adult women of
reproductive age. We believe OBE2109 has the potential to provide an alternative to surgery, which is the most common
treatment for uterine fibroids. One of the three Phase 2a clinical trials in patients of Japanese descent with endometriosis,
KLH1202, included a subgroup of 57 patients with both endometriosis and uterine fibroids.

Completed Phase 2a Clinical Trial

In the KLH1202 clinical trial, 57 patients presented with uterine fibroids in addition to endometriosis. For these patients,
both menstrual bleeding and uterine volume were evaluated.

Efficacy Results

As shown in Figure 7 below, we observed a dose-dependent reduction in the percentage of days in which bleeding occurred
during the 12-week treatment period in patients treated with OBE2109.

Figure 8 below. In addition, most patients stopped bleeding within a few weeks of treatment initiation in the 100 mg and
200 mg group, as shown in Figure 8 below.

These patients experienced a dose-dependent reduction in uterine volume, while no meaningful reduction in uterine volume
was observed in the placebo group, as shown in Figure 9 below. Reducing uterine volume is important for the treatment of
uterine fibroid patients, as patients with lower uterine volume may be eligible for less invasive surgical procedures, such as
a hysterectomy by vaginal route rather than abdominal route. In addition, uterine volume is correlated with several
symptoms of uterine fibroids, such as urinary incontinence and frequency.

Completed Phase 1 Clinical Trials

In 2017, we conducted a Phase 1 PK and PD clinical trial to assess two different doses of add-back therapy in patients
receiving 100 mg and 200 mg doses of OBE2109 over six weeks. The results of this clinical trial, which we announced in
June 2017, supported our add-back therapy dose and OBE2109 doses being utilized in the PRIMROSE clinical trials. We
believe that a 100 mg dose of OBE2109 may be able to control symptoms in a significant proportion of patients without
requiring add-back therapy. In addition, in 2016 we completed a Phase 1 trial to assess the impact of OBE2109 on CYP3A4
induction, which is responsible for most metabolism of add-back back therapy. In this trial, we observed no relevant
CYP3A4 induction, which we believe suggests that OBE2109 will not interfere with add-back therapy.

Clinical Development Plan—Heavy Menstrual Bleeding Associated with Uterine Fibroids

Based on feedback we received from the FDA in November 2016, we commenced the two PRIMROSE Phase 3 clinical
trials in patients with heavy menstrual bleeding associated with uterine fibroids in the first half of 2017. The PRIMROSE
clinical trials each have a target enrollment of approximately 500 patients. PRIMROSE 1 is being conducted in the United
States and PRIMROSE 2 is being conducted in the United States and in Europe. We expect to report 6-month primary
endpoint results from both PRIMROSE Phase 3 clinical trials in the second half of 2019. We also are further assessing the
efficacy of a 200 mg dose of OBE2109 both with and without add-back therapy in the ongoing PRIMROSE clinical trials.
We believe that the 200 mg dose will require add-back therapy to prevent excessive bone mineral density loss.

Figure 10 below depicts the trial design of the Phase 3 PRIMROSE clinical trials:

ObsEva S.A. - Annual Report 2017

Figure 10: Design of Phase 3 PRIMROSE Clinical Trials

Business Update

Throughout the PRIMROSE clinical trials, patients will collect and deliver their used sanitary protection to a central
laboratory analysis using a validated alkaline hematin method. In addition, patients will report their bleeding status on a
daily basis with an electronic diary.

The PRIMROSE clinical trials will have a 52-week evaluation period. The primary endpoint of these clinical trials will be
the reduction from baseline at week 24 of menstrual blood loss, defined as menstrual blood loss of less than 80 mL and
equal to or greater than a 50% reduction from baseline, assessed with the alkaline hematin method. A key secondary
endpoint will be the bone mineral density after 24 weeks of treatment assessed with a dual-energy x-ray absorptiometry
scan. After the 52-week evaluation period, all patients will be followed for an additional, 24-week period that will be
treatment free. We expect to report primary endpoint 24-week data from the PRIMROSE Phase 3 clinical trials in the
second half of 2019, and the 52-week data are expected in the first half of 2020. If the results from these trials are
favorable, we intend to submit an NDA in the second half of 2020.

Safety Results of Phase 1, Phase 2a and Ongoing Phase 2b and Phase 3 Clinical Trials

As of February 28, 2018, more than 1,200 subjects have been exposed to OBE2109 in completed and ongoing clinical
studies and OBE2109 has been generally well tolerated.

In the three completed Phase 1 clinical trials (n=177), adverse events were reported with similar frequency in all groups,
including the placebo group. No serious adverse events were reported.

In the three completed Phase 2a clinical trials (n=128), almost all of the adverse events were mild. The most common
adverse events were abnormal bleeding from the uterus, contracting a cold, headaches and hot flashes. Most hot flashes
were mild, three were moderate in severity and none were severe. No serious adverse events were reported in the KLH1203
trial. A single serious adverse event was observed in each of the KLH1201 and KLH1202 trials and both were determined
by the principal investigators to be unrelated to OBE2109.

Nolasiban in IVF

We are developing nolasiban as an oral oxytocin receptor antagonist, to improve clinical pregnancy and live birth rates in
women undergoing embryo transfer after IVF, including intracytoplasmic sperm injection, or ICSI. We have observed
nolasiban’s ability to improve uterine receptivity by decreasing uterine contractions, improving uterine blood flow and
enhancing the receptivity of the endometrium to embryo implantation. We in-licensed nolasiban from Merck Serono, which
previously completed preclinical studies and Phase 1 clinical trials in 103 healthy female volunteers that evaluated the
safety and PK profile of nolasiban. We completed a 247-patient Phase 2 clinical trial of nolasiban in women undergoing
IVF, which we refer to as the IMPLANT trial. In the IMPLANT trial, nolasiban did not reach the primary endpoint of
demonstrating a statistically significant increase in pregnancy rate at six weeks after ET. In our post-hoc analysis, which
excluded patients with progesterone levels in the top quartile of the patient pool, we identified a statistically significant
dose-proportional increase in pregnancy rate at 10 weeks and live birth rate. We believe that high progesterone levels can
lead to a premature closing of the embryo implantation window. Based on these results, we believe that nolasiban could
represent a compelling option for increasing IVF outcomes. We initiated our IMPLANT2 European Phase 3 clinical trial in
women undergoing IVF in March 2017, announced patient recruitment completion in September 2017, and reported data
for the primary endpoint in February 2018. In the IMPLANT2 clinical trial, we observed that Nolasiban significantly
increased ongoing pregnancy rate at 10 weeks. The primary endpoint of the clinical trial was met, with an absolute increase
in ongoing pregnancy rate at 10 weeks of 7.1% (placebo 28.5% and nolasiban 35.6%, p = 0.031). This represents a relative
increase of 25% in the ongoing pregnancy rate after administration of nolasiban compared to placebo. Nolasiban was
generally well tolerated with a safety profile similar to placebo.

Background on Assisted Reproductive Technology (IVF/ICSI)

Infertility is a disease of the reproductive system that impairs the body’s ability to reproduce. From 2006 to 2010, the
inability to have a child affected approximately 6.7 million women in the United States, which represented approximately
11% of the reproductive-age population. An increasing number of women in developed countries are delaying having
children until their mid-thirties, which has resulted in decreased fertility rates and increased demand for reproductive
therapies.

ART is used primarily for infertility treatments. According to the Centers for Disease Control and the European Society of
Human Reproduction and Embryology, IVF represents the vast majority of ART treatments or procedures. IVF helps
women achieve pregnancy by the collection of mature eggs in the ovaries, followed by fertilization and early embryo
development in the laboratory before transfer of the embryos into the womb. According to the European Society of Human
Reproduction and Embryology, every year about 1.6 million ART treatments are performed worldwide. In Europe, ART
treatments doubled from 2000 to 2010, and approximately 620,000 IVF treatments were performed in 2012. In the United
States, IVF treatments increased by 41.7% from 2010 to 2014.Approximately 230,000 IVF treatments were performed in
the United States in 2015. In Japan, approximately 368,000 IVF treatments were performed in 2013.

ObsEva S.A. - Annual Report 2017

The first step in IVF is stimulation of egg production. Approximately ten days later, the eggs are harvested from the
ovaries, otherwise known as ovum pick-up, or OPU, and co-incubated with sperm cells, with this day being referred to as
Day 0. The resulting embryos are either used for fresh transfer to the uterus over the next three to five days or frozen for
future use. In Europe in 2012, we estimate that approximately 39% of all embryo transfers occur three days after Day 0 and
an additional 36% occur five days after Day 0, with the remaining 25% frozen for future transfer. In the United States in
2015, we estimate that the respective percentages were 19% (Day 3, or D3), 38% (Day 5, or D5) and 43% (frozen-thawed
embryo transfers). The figure below depicts the IVF procedure:

The cost of one IVF cycle varies between $8,000 to $15,000 in the United States, EUR 2,000 to EUR 10,000 in Europe and
$3,000 to $6,000 in Japan. As of 2006, fertility drugs account for more than $2,000 of the cost of a treatment cycle. Most
patients require multiple fertility treatment cycles. IMS Health Incorporated estimates that global sales of fertility drugs
exceeded $2 billion in 2014.

The success of IVF depends on the quality of the embryo, the transfer procedure and ultimately the receptivity of the
uterus. In order for the embryo transfer to be successful, it is important for the uterus to be receptive to embryo
implantation, which includes a proper hormonal environment, appropriate blood flow within the uterus, and minimal
uterine contractions at the time of embryo transfer. The endometrium is the inner layer of the uterus that is in direct contact
with the implanting embryo. Uterine contractions occur throughout the course of a woman’s menstrual cycle and the
frequency and intensity of the contractions depend on the phase of the cycle. In a study published in Human Reproduction
in 1998, after IVF, the rate of uterine contractions assessed at the time of embryo transfer was observed to be negatively
correlated with pregnancy rates as shown in the figure below.

ObsEva S.A. - Annual Report 2017

Role of Oxytocin in Embryo Implantation

Oxytocin is a hormone that is secreted by the pituitary gland. Oxytocin receptors are present on the uterus smooth muscle
cells, the endometrium and the uterus arteries. The release of oxytocin by the pituitary gland activates oxytocin receptors,
which results in uterine contractions. As shown in the graphic below, blocking the activation of the uterine oxytocin
receptors at the time of embryo transfer may enhance uterine receptivity by decreasing uterine contractions, improving
uterine blood flow and enhancing the receptivity of the endometrium to embryo implantation, which can lead to increased
clinical pregnancy and live birth rates.

ObsEva S.A. - Annual Report 2017

Business Update

A systematic review and meta-analysis of investigator-sponsored trials conducted in 2014 and published in Fertility &
Sterility concluded that pregnancy rates doubled with the infusion of an oxytocin receptor antagonist at the time of embryo
transfer. As part of this analysis, it was observed that improvement in pregnancy rates was not restricted to women with a
high rate of uterine contractions. According to this analysis, additional mechanisms, such as endometrium receptivity and
uterine blood flow, may also contribute to improving pregnancy rates. In a recent trial published in 2016 involving patients
with endometriosis undergoing frozen-thawed embryo transfer, clinical pregnancy rates were approximately 20% higher
after treatment with an oxytocin receptor antagonist, representing a 51% increase relative to the placebo. In addition,
according to studies published in Archives of Gynecology and Obstetrics in 2011, women who received an oxytocin
receptor antagonist after embryo transfer, were observed, based on three dimensional power doppler ultrasound, to have
improved characteristics for uterine receptivity, including enhanced endometrial blood flow.

Limitations of Current Treatment Options
Currently, there are no oxytocin receptor antagonists approved for use in connection with IVF.

Potential Therapeutic Benefits of nolasiban

We are developing nolasiban, an oxytocin receptor antagonist, for use in connection with IVF. We believe nolasiban has
the potential to offer the following therapeutic benefits:

•

Increased live birth rate. In the IMPLANT2 clinical trial, we observed that Nolasiban significantly increased
ongoing pregnancy rate at 10 weeks: Pooled D3/D5 (primary): Placebo 28.5%, Nolasiban 35.6%, p=0.03 (7.1%
absolute increase, 25% relative increase). The largest increase in ongoing pregnancy rate was seen with D5 ET,
Placebo 34.7%, Nolasiban 45.9%, p=0.03 (11.2% absolute increase, 32% relative increase). Similar results
were demonstrated on Clinical Pregnancy Rate at 6 weeks and Pregnancy Test at 2 weeks. We expect to report
live birth rate and 28 day neonatal follow-up data in the fourth quarter of 2018, and 6 month infant follow-up in
2019.

Convenience of administration. Nolasiban is an oral oxytocin receptor antagonist, that is being studied as a
one-time single dose pill which could be easily incorporated into IVF procedures.

Fast and sustained therapeutic effect. In clinical trials, nolasiban was observed to be rapidly absorbed in the
body and, in the case of the 900 mg dose, to maintain effective concentrations in the body for three days after
treatment, potentially allowing for a single administration at the time of embryo transfer.

Favorable safety profile. In Phase 1 and Phase 2 clinical trials, single doses of nolasiban were well tolerated by
patients. In addition, extensive testing in animal models around the time of embryo implantation and during
pregnancy has not revealed any concerns regarding embryo toxicity. Topline IMPLANT2 clinical trial results
that were announced in February 2018 showed rates of treatment discontinuation and treatment emergent
adverse events that were very low and comparable to placebo rates, and the few reported serious adverse event
reports were numerically higher for placebo than for nolasiban, although none were reported to be related to
treatment.

Nolasiban Preclinical and Clinical Development

Nolasiban was discovered and initially developed by Merck Serono. Following our in-license of nolasiban from Merck
Serono in 2013, we submitted an IND for nolasiban, which became effective in January 2015. Under that IND, we
completed a Phase 2 clinical trial of nolasiban in 2016. Though nolasiban did not reach the primary endpoint of a
statistically significant increase in pregnancy rate six weeks after the ET based on our post-hoc analysis of the Phase 2 data,
we identified a statistically and clinically significant dose-proportional increase in ongoing pregnancy rate at week 10 and
live birth rate. The post hoc intended to correct for an unbalance in the number of patients with poor outcome related to
excessive progesterone level on the day of ET. In March 2017, we initiated our IMPLANT2 European Phase 3 clinical trial
in women undergoing IVF to further evaluate the efficacy and safety of a single oral dose of nolasiban, announced patient
recruitment completion in September 2017, and reported positive top line results in February 2018. Based on these results,
we intend to seek feedback from regulatory authorities in Europe and the United States on any necessary additional clinical
requirements, and also solicit guidance on the regulatory registration path forward. Additionally we will reactivate our IND
and request a mid-2018 meeting with the FDA before commencing any U.S. clinical trials.

Preclinical Studies and Phase 1 Clinical Trials

In preclinical studies, the ability of nolasiban to inhibit uterine contraction was observed, and there were no tolerance or
safety concerns. Specifically, studies were conducted focusing on the reproductive toxicology in rats and rabbits during the
time of implantation, and such studies did not reveal concerns of embryo toxicity after repeated exposure to nolasiban.

In single and multiple ascending dose Phase 1 clinical trials conducted in the United Kingdom by Merck Serono, nolasiban
was tested in 103 healthy female volunteers with single doses up to 1,500 mg and multiple doses up to 900 mg for seven
days. There were no safety signals, trends in adverse events or negative findings from vital signs or laboratory parameters.
Nolasiban was observed to be quickly absorbed, reaching maximum concentration in approximately two hours, and to have
a dose-proportional PK profile and a half-life that could support once daily dosing. There was no observed food effect.

Completed Phase 2 Clinical Trial

In 2016, we completed a Phase 2, double-blind, placebo-controlled, dose ranging, clinical trial of nolasiban in women
undergoing IVF, which we refer to as the IMPLANT trial. This trial enrolled 247 women across 26 fertility clinics in five
European countries. Patients were between the ages of 18 and 36, were currently undergoing medically indicated IVF and
had no more than one previous IVF cycle failure. The study evaluated three doses of nolasiban, 100 mg, 300 mg or 900 mg,
compared to placebo. Patients received a single oral dose approximately four hours before a Day 3 fresh embryo transfer.
The patients were evaluated once pregnant at weeks 2, 6 and 10 and we also evaluated the infants born for up to six months
after birth. Assuming a 20% pregnancy rate in placebo and a 40% pregnancy rate in nolasiban at 900 mg, the number of
patients in each arm of the trial provided an 80% chance to show a statistically significant increase in pregnancy rate from
placebo through ascending doses of nolasiban using a trend test. We believed this was the appropriate trial design to
determine dose effect and guide future clinical development.

The trial design is summarized below:

The primary endpoint of this trial was:

•

the percentage of women with an intra-uterine pregnancy with positive embryo heartbeat at six weeks after the
ET day.

Secondary endpoints included:

•

the percentage of women with a positive blood pregnancy test at 14 days after the OPU day;

the percentage of women with an intra-uterine pregnancy with positive embryo heartbeat at 10 weeks after the
OPU day;

the embryo-implantation rate defined as the number of intra-uterine embryos with positive heartbeat at six
weeks after the ET day divided by the number of embryos transferred; and

the absolute and relative change from baseline, prior to nolasiban or placebo administration, to the time of
embryo transfer, which is about 3.5 hours after nolasiban/placebo administration and prior to embryo transfer,
in the rate of uterine contractions per minute.

Efficacy Results

As shown in Figure 11 below, which we refer to as the “Full Set Analysis,” the overall percentage of patients with an intra-
uterine pregnancy with a positive heartbeat at six weeks after ET and the live birth rate were increased by over 9%,
equivalent to a 26% increase relative to placebo. The median uterine contractions decreased by 8.7%, 4.0% and 13.3% for
the 100 mg, 300 mg and 900 mg groups, respectively, compared to placebo. However, statistical significance was not
reached for the primary endpoint, as indicated in the “Trend Test” column in Figure 11 below. We believe the lack of
statistical significance was attributable to the limited sample size and based on the 300 mg dose group of nolasiban which
had lower clinical pregnancy and live birth rates than the 100 mg and 900 mg treatment groups.

The trend test is a statistical technique that was used to determine whether there was a statistically significant linear
relationship between the dose of nolasiban administered and the amplitude of the increase in ongoing pregnancy rate at six
weeks after the ET day. In this Phase 2 IMPLANT trial, we considered a p-value of less than 0.10 to be statistically
significant.

Figure 11

Following our receipt of the initial data, we reviewed the patients’ characteristics within each of the dose groups. From this
review, we discovered that patients in the 300 mg group demonstrated higher estradiol levels and higher progesterone
levels prior to embryo transfer than in the other groups. We believe that high estradiol levels are responsible for the earlier
expression of progesterone receptors, which induce advancement of endometrial maturation, and that high progesterone
levels can lead to a premature closing of the embryo implantation window, preventing or impairing the embryo
implantation. Therefore, we subsequently conducted a post-hoc analysis of the results of the Phase 2 clinical trial, removing
patients with a progesterone level in the top quartile of the patient pool. There were 25 patients excluded in this post-hoc
analysis from the 300 mg group, while only 16, 12 and 11 patients were excluded in this post-hoc analysis from the
placebo, 100 mg and 900 mg groups, respectively, which we believe demonstrates the imbalance between the 300 mg
group and the other groups.

In our post-hoc analysis, we identified a statistically significant relationship between the dose of nolasiban and the ongoing
pregnancy rate at week 10 and live birth rate, with an increase from 30.6% for placebo to 51.0% for 900 mg nolasiban at
week 10 and for live birth rate, equivalent to a 67% increase relative to placebo (trend test p-value < 0.05). The results of
our post-hoc analysis are shown in Figure 12 below:

ObsEva S.A. - Annual Report 2017

Business Update

Based on these results, we believe that a single 900 mg dose of nolasiban administered just before embryo transfer has the
potential to increase clinical pregnancy and live birth rates following IVF.

Phase 2 Clinical Safety Results

In the IMPLANT trial, nolasiban was well tolerated at doses up to 900 mg. Adverse events were reported through 10 weeks
following the OPU day. Increased doses were not observed to result in increased occurrence of adverse events. The most
common adverse events were determined to be related to pregnancy, menstrual bleeding or the IVF procedure and occurred
at similar frequencies in the placebo and active treatment groups. Serious adverse events were reported in six patients and
included ectopic pregnancy in three patients, and adnexal torsion, vaginal hemorrhage and ovarian hyperstimulation
syndrome in one patient each. None of these serious adverse events were determined by the investigator to be related to the
treatment and none caused trial discontinuation. One patient in the nolasiban 900 mg group discontinued participation in
the trial due to a non-serious adverse event of ovarian hyperstimulation syndrome, which was determined by the
investigator to be unrelated to treatment. Only three adverse events, which occurred in patients in the 300 mg group, were
considered related to treatment (mild nausea, mild dizziness and mild rash), and the patients fully recovered from the
adverse events.

In the trial, ongoing pregnancies were followed up to 28 days post-delivery. As expected with human pregnancies, some
congenital malformations were observed both in the placebo group and the treatment groups. There appeared to be no
relationship between the nolasiban dose and the incidence of the congenital malformations, as shown in Figure 13 below,
and none were determined by the investigator to be related to treatment. In addition, nolasiban was not associated with an
increase in ectopic pregnancy or in intra-uterine growth retardation.

Ongoing Phase 3 Clinical Trial and Clinical Development Plan

We have advanced nolasiban into Phase 3 clinical development to evaluate its potential to improve clinical pregnancy and
live birth rates for women undergoing IVF. We are conducting a Phase 3 clinical trial in Europe, which we refer to as
IMPLANT2, where we believe more IVF treatments are conducted. The study included eligibility criteria to exclude
patients with high progesterone level on day of hCG from entering the trial.

IMPLANT2 is a randomized, double blind, placebo controlled clinical trial that included 778 patients from 41 fertility
clinics across nine European countries. Patients received either a single 900 mg dose of nolasiban or placebo (1:1) orally on
the day of ET. Recruitment included patients undergoing single, fresh ET on day 3 (D3, n=388) or on day 5 (D5, n=390)
after oocyte retrieval. The primary endpoint of the trial was ongoing pregnancy as determined by ultrasound at 10 weeks
following ET. The pre-defined primary analysis was conducted on the pooled population of D3 and D5 ET. Secondary
endpoints include clinical pregnancy rates at six weeks after the ET day, live birth rates, maternal, newborn baby and infant
follow-up. The design of this IMPLANT2 European Phase 3 clinical trial is shown in Figure 14 below.

Figure 14

We initiated this IMPLANT2 European Phase 3 clinical trial in March 2017, announced patient recruitment completion in
September 2017, and reported data for the primary endpoint in February 2018.

These top line results include efficacy and safety data up to week 10 of pregnancy following embryo transfer.
Demographics and baseline characteristics were comparable between groups. The primary endpoint of the clinical trial was
met, with an absolute increase in ongoing pregnancy rate at 10 weeks of 7.1% (placebo 28.5% and nolasiban 35.6%, p =
0.031). This represents a relative increase of 25% in the ongoing pregnancy rate after administration of nolasiban compared
to placebo. In the ET D5 subgroup, the absolute increase was 11.2% in favor of nolasiban (placebo 34.7% and nolasiban
45.9%, p = 0.034). This represents a relative increase in ongoing pregnancy rate of 32% after administration of nolasiban
compared to placebo. In the ET D3 subgroup, there was a statistically non-significant 3.1% absolute increase in favor of
nolasiban (placebo 22.2% and nolasiban 25.3%, p > 0.05), or a 14.0% relative increase in ongoing pregnancy rate after
administration of nolasiban compared to placebo. In addition, nolasiban was well tolerated, with low rates of treatment
discontinuation that were comparable between treatment and placebo. The safety profile of nolasiban was also similar to
placebo, with a total of 9 (2.3%) serious adverse events in the placebo group and 4 (1.0%) in the nolasiban group. None of
these serious adverse events were reported to be related to treatment.

Based on the IMPLANT2 results, we plan on seeking feedback from regulatory authorities in Europe and in the United
States on any additional future registration requirements. Additionally we will reactivate our IND and request a mid-2018
meeting with the FDA before commencing any U.S. clinical trials.

OBE022: Our PGF2α Receptor Antagonist for the Treatment of Preterm Labor (GA 24-34 weeks)

We are developing OBE022 as a potential first-in-class, once daily, oral and selective PGF2α, receptor antagonist for the
treatment of preterm labor in weeks 24 to 34 of pregnancy. PGF2α is a naturally occurring prostaglandin that acts to induce
labor in pregnant women. Through specific antagonism of the PGF2α receptor, OBE022 is designed to control preterm labor
by reducing inflammation, decreasing uterine contractions and preventing cervical changes and membrane ruptures. Based
on its PK profile and efficacy observed in animal models, we believe OBE022 has the potential to become a first-in-class
therapy to suppress premature labor and delay or avoid preterm birth while also being safe for the fetus. In February 2017,
we completed a Phase 1 clinical trial assessing the safety, tolerability and PK profile of OBE022 in healthy post-
menopausal female volunteers after single doses of 10 mg to 1,300 mg and multiple doses between 100 mg per day and
1,000 mg per day over 7 consecutive days. OBE022 was observed to have a favorable pharmacokinetic profile, no
clinically significant food effect, a favorable safety profile and to be well-tolerated at doses up to 1,300 mg after single dose
administration and up to 1,000 mg per day after multiple dose administration over 7 days, each of which are above the
estimated clinical effective dose. In March 2017, we completed a set of drug-drug interaction, or DDI, Phase 1 clinical
pharmacology studies investigating the safety, tolerability and PK profile of OBE022 when combined with magnesium
sulfate, atosiban, nifedipine or betamethasone (medications typically used in patients with preterm labor) in pre-
menopausal female volunteers. OBE022 in combination with those drugs was observed to have a favorable safety profile
and to be well-tolerated up to 1,100 mg per day, which was the highest tested dose. In December 2017, we announced the
initiation of our Phase 2a proof-of-concept clinical trial of OBE022 known as PROLONG. PROLONG will enroll
approximately 120 pregnant women at 24-34 weeks gestation who are experiencing preterm labor symptoms. Following
the open-label Part A of the trial in 8 patients to assess PK/PD and initial safety, a placebo-controlled double blind, Part B
will enroll up to an additional 120 patients, from which we expect initial efficacy results may be available in late 2018.

Background and Impact of Preterm Labor

Preterm labor, defined as the body commencing the birthing process prior to 37 weeks, is characterized by uterine
contractions, cervical dilation and rupture of the fetal membranes that surround and protect the fetus during pregnancy.
According to a study published in the Lancet in 2012, approximately 15 million babies were born preterm in 2010,
accounting for 11.1% of all live births worldwide. In the 65 countries with reliable data for preterm birth, 62 countries had
increasing rates of preterm birth over the period from 1990 to 2010. According to the National Center for Health Statistics,
the United States’ preterm birth rate was 9.6% in 2014, which, according to the March of Dimes Foundation, ranks among
the worst of high-resource countries. In 2007, the Institute of Medicine reported that the cost associated with premature
birth in the United States was approximately $26.2 billion each year.

According to the World Health Organization, preterm birth is the leading worldwide cause of neonatal death, defined as
death in the first 28 days of life. Preterm birth complications are also the leading cause of death in children under the age of
five, having caused nearly one million deaths in 2013 worldwide. Infants who survive preterm birth may have lifelong
health problems such as cerebral palsy, vision and hearing impairment and intellectual disabilities. Approximately one-third
of children born prematurely need special school services, according to the March of Dimes Foundation.

Role of Prostaglandins in Preterm Labor

Prostaglandins play a major role in the normal function of the female reproductive system. There are various prostaglandins
at work in the human body with different functions, such as prostaglandin E2, or PGE2, and PGF2α . PGE2 and PGF2α have
opposing effects on the female reproductive system. PGE2 causes the widening of blood vessels. PGE2 is produced by the
fetus and is important in fetal physiology and development, and therefore, blocking its action has the potential to produce
unwanted fetal effects. By contrast, PGF2α is a constrictor of the myometrium and uterine blood vessels. PGF2α is present in
the uterus and plays a major role in the initiation and process of childbirth. PGF2α modulates various functions leading to
the progression of labor and is involved in all aspects of childbirth including ripening of the cervix, membrane rupture and
induction of uterine contraction. PGF2α promotes the establishment of a pro-inflammatory intra-uterine environment by
stimulation of pro-inflammatory cytokine and chemokine production in the myometrium, leading to the initiation of labor.

Limitations of Current Treatment Options

Various classes of pharmaceutical agents that decrease uterine contractions, also known as tocolytics, are used to delay
preterm labor. These different classes act on the uterine muscle through various mechanisms of action but have limited
efficacy, restrictive safety issues and are all used off-label in the United States. These different classes include nifedipine, a
calcium channel blocker, magnesium sulfate, indomethacin (a NSAID) and glyceryl trinitrate, each of which have been
observed to have limited efficacy and/or safety issues. Beta-adrenergic agonists have been largely discontinued because of
severe maternal cardiovascular side effects. Atosiban, an oxytocin receptor antagonist, is approved in Europe but not in the
United States. It can delay preterm labor, but is administered through a bolus injection followed by an infusion and is not
indicated for dosing beyond 48 hours.

Reviews of these different classes of tocolytic drugs concluded that prostaglandin synthesis inhibitors, such as NSAIDs,
provided the best efficacy for delaying labor at 48 hours and seven days. According to a study published in Obstetrics &
Gynecology in 2009, prostaglandin antagonists were most effective at delaying delivery at 48 hours and seven days among
the class of drugs available in the United States. Delaying delivery as long as possible up to full term is ideal, but delaying
delivery by at least 48 hours is significant because betamethasone (a glucocorticosteroid) can be administered to the mother
to mature the baby’s lungs so the baby can potentially breathe on its own. The table below, which shows the results of that
study, displays the percentage of patients that did not deliver a baby at various time points following treatment.

Figure 15: Weighted Percentages of Tocolytic Agents for Efficacy

Currently available prostaglandin inhibitors, such as the NSAID indomethacin, act by non-selective inhibition of
prostaglandin-forming enzymes, thus blocking the generation and signaling of many prostaglandin sub-types, including
both PGE2 and PGF2α. Because they potentially adversely affect fetal physiology, use of NSAIDs is restricted to 48 hours
in women at gestational age below 32 weeks, due to these unwanted side effects. According to a publication in 2015 in the
American Journal of Obstetrics and Gynecology, the most concerning side effects associated with the non-selective
prostaglandin inhibitors include severe conditions in newborn babies, such as renal function impairment, constriction of the
blood vessel connecting the pulmonary artery to the aorta, bleeding in the area surrounding the fluid-filled areas of the
brain, necrotizing enterocolitis, which is a serious condition that occurs when the intestinal tissue blood flow is damaged
and begins to die, and periventricular leukomalacia, which is a form of brain injury that can lead to serious disabilities.

As a result of the limited efficacy and unfavorable safety profile of many current therapies used off-label to treat preterm
labor, we believe there remains a significant unmet need for a selective prostaglandin inhibitor focused on the inhibition of
only PGF2α to delay preterm labor and provide a safe treatment option for both mother and child.

OBE022 Preclinical and Clinical Development

OBE022 was discovered and initially developed by Merck Serono as a selective inhibitor of PGF2α. We in-licensed
OBE022 from Merck Serono in 2015. In preclinical studies, OBE022 was observed to reduce uterine contractions and to
exert a synergistic effect in combination with nifedipine to delay delivery. We advanced OBE022 into Phase 2a proof-of-
concept clinical trial in December 2017 to assess the safety and efficacy of OBE022 to delay birth in women 24 to 34
weeks pregnant who face preterm labor and potentially preterm delivery. In February 2017, we completed a Phase 1
clinical trial assessing the safety, tolerability and PK profile of OBE022 in healthy post-menopausal female volunteers after
single doses of 10 mg to 1,300 mg and multiple doses between 100 mg per day and 1,000 mg per day over 7 consecutive
days. OBE022 was observed to have a favorable PK profile, no clinically significant food effect, a favorable safety profile
and to be well-tolerated at doses up to 1,300 mg after single dose administration and up to 1,000 mg per day after multiple
dose administration over 7 days. In March 2017, we completed a set of DDI Phase 1 clinical pharmacology studies
investigating the safety, tolerability and PK profile of OBE022 when combined with magnesium sulfate, atosiban,
nifedipine or betamethasone (medications typically used in patients with preterm labor) in pre-menopausal female
volunteers. OBE022 in combination with those drugs was observed to have a favorable safety profile and to be well-
tolerated up to 1,100 mg per day, which was the highest tested dose.

Preclinical Development

In the preclinical pharmacology, PK and toxicology studies conducted by Merck Serono, OBE022 was observed to be a
highly selective, competitive and reversible PGF2α receptor antagonist with over 100 times the affinity for it compared to
other prostaglandin receptor subtypes. OBE022 has been observed to have tocolytic effects in vitro and in vivo by
markedly reducing spontaneous uterine contractions in a preterm labor animal model. At the Society for Reproductive
Investigations’ 64th Annual Scientific Meeting in March 2017, we presented results of a non-clinical study in which we
observed that OBE022 exerted a synergistic effect in combination with nifedipine on the delay of delivery in an animal
model for preterm labor. The study evaluated the effect of OBE022 and nifedipine, alone and in combination with each
other, on an animal model of RU486-induced birth in pregnant mice. The induction of labor by the antiprogestin RU486
results from inhibition of progesterone activation leading to the up-regulation of labor-associated proteins as seen in the
case of idiopathic preterm labor. Compared to the vehicle control, we observed nifedipine (5mg/kg, taken orally), as well as
OBE022 (100mg/kg, taken orally), alone resulted in statistically significant delays in RU486-induced preterm labor. We
also observed a synergistic effect of combination treatment with OBE022 and nifedipine on the delay of delivery when
compared to vehicle, nifedipine or OBE022 alone (p<0.001, p<0.001 and p<0.01, respectively). Preclinical studies have
also been conducted to support oral administration of OBE022 in humans. Overall, the toxicological profile of OBE022
observed in repeated-dose toxicity studies in rats and dogs as well as reprotoxicity in rabbits and rats appeared to be benign.
We also conducted safety studies to evaluate OBE022 compared to NSAIDs in pregnant rats prior to delivery. In these
studies, we observed that the NSAID indomethacin induced, as expected, constriction of the blood vessel connecting the
pulmonary artery to the aorta and impaired the renal function in the newborn rats, while OBE022 did not. In addition, we
have observed that OBE022 does not inhibit platelet aggregation whereas the NSAIDs were confirmed to significantly
inhibit it, which is considered to be a potential risk factor for neonatal tissue hemorrhagia, e.g. periventricular brain
hemorrhagia. Based on the results of these preclinical studies, we believe that OBE022 has the potential to be an effective,
safer tocolytic agent for the treatment of preterm labor.

Phase 1 Clinical Trials

We completed a Phase 1 clinical trial assessing the safety, tolerability and PK profile of OBE022 when administered in
approximately 70 healthy post-menopausal female volunteers as single and multiple ascending doses at one site in the
United Kingdom. As PGF2α is also involved in uterine contractions and the related pain that can occur during normal
menstruation in non-pregnant women, we are assessing the feasibility of measuring the ability of OBE022 to reduce the
intra-uterine pressure and the pelvic pain scores in healthy female volunteers of child bearing age during menstruation.
From the single doses administered of 10 mg to 1,300 mg and multiple doses between 100 mg per day and 1,000 mg per
day administered over 7 consecutive days in the completed Phase 1 clinical trial, we observed that pro-drug OBE022 was
readily absorbed and rapidly converted into its equally active stable metabolite OBE002. The plasma level of OBE002
increased with increasing doses of OBE022 reaching exposure levels that were anticipated to be clinically relevant within
an hour following administration. There was no clinically significant food interaction with peak exposures reduced to 80%
and AUC staying bioequivalent. The mean half-life of OBE002 ranged between 8 and 11 hours following administration of
a single dose and between 22 to 29 hours after multiple doses (figure 16). Single and multiple administrations of OBE022

ObsEva S.A. - Annual Report 2017

Business Update

were well tolerated at all doses. There have been no serious adverse events and no clinically relevant changes in safety
parameters.

Figure 16:

We also completed a set of DDI Phase 1 clinical pharmacology studies investigating the safety, tolerability and PK profile
of OBE022 when combined with therapeutic doses of magnesium sulfate, atosiban, nifedipine or betamethasone
(medications typically used in patients with preterm labor) in pre-menopausal female volunteers. We performed an open-
label, randomized, three-period crossover trial assessing co-administration of single doses of OBE022 (1100 mg) and
MgSO4 (15.5g) and also performed an open-label, single-sequence crossover trial assessing the interactions of OBE022
(1000 mg/d) at steady-state co-administered with single doses of atosiban (60.75 mg), nifedipine (20 mg) and
betamethasone (12 mg). Both trials enrolled 12 healthy non-pregnant women of reproductive age at one clinical center in
the United Kingdom. There were no clinically relevant pharmacokinetic interactions between OBE022 and MgSO4,
betamethasone or atosiban; however, nifedipine exposure increased notably. Co-administration of OBE022 with MgSO4,
betamethasone, atosiban and nifedipine was generally well tolerated.

Clinical Development Plan

Based on these Phase 1 clinical trial results, we initiated the PROLONG Phase 2a proof-of-concept clinical trial. The trial
objectives are to assess the safety and efficacy of OBE022 when co-administered with atosiban, to delay birth after oral
administration in pregnant women who face preterm labor and potentially preterm delivery. The targeted patient population
will include women who are at least 24 weeks and less than 34 weeks pregnant, with intact membranes, presenting with
spontaneous preterm labor for which they receive atosiban for 48 hours and no contraindications to a prolongation of
pregnancy. Giving birth between 34 weeks and 37 weeks is generally not viewed as high risk to the baby and therefore
using pharmaceutical agents to delay child birth is controversial during this period. Based on the results of this trial, and
after receiving expert and regulatory feedback, we will decide whether to further develop OBE022 as a self-standing
tocolytic or in combination with atosiban or another currently used tocolytic.

Commercialization

We have not yet established a sales, marketing or product distribution infrastructure. In order to commercialize any of our
product candidates if approved for commercial sale, we must either establish a sales and marketing organization with
technical expertise and supporting distribution capabilities or collaborate with third-parties that have sales and marketing
experience. As we move our product candidates through development toward regulatory approval we will evaluate several
options for each product candidate’s commercialization strategy. These options include building our own internal sales
force, entering into a joint marketing partnership with another pharmaceutical or biotechnology company, or out-licensing
the product to another pharmaceutical or biotechnology company.

Manufacturing

We rely on CMOs to produce our product candidates in accordance with the FDA’s cGMP regulations for use in our
clinical trials. The manufacture of pharmaceuticals is subject to extensive cGMP regulations, which impose various
procedural and documentation requirements and govern all areas of record keeping, production processes and controls,
personnel and quality control. Replacement of any of our CMOs would require us to qualify new manufacturers and
negotiate and execute contractual agreements with them. If any of our supply or service agreements with our CMOs are
terminated, we will experience delays and additional expenses in the completion of the development of and obtaining
regulatory approval for OBE2109, nolasiban and OBE022.

To meet our projected needs for clinical supplies to support our activities through regulatory approval and commercial
manufacturing, the CMOs with whom we currently work will need to increase scale of production or we will need to secure
alternate suppliers. Pursuant to the Kissei license and supply agreement, we have agreed to exclusively purchase the active
pharmaceutical ingredient for OBE2109 from Kissei who is now obtaining OBE2109 cGMP supply from two suppliers,
both of which are different from the supplier who received the warning letter from the FDA in November 2016. If we are
unable to obtain sufficient quantities of our products candidates or receive raw materials in a timely manner, we could be
required to delay our ongoing clinical trials and seek alternative manufacturers, which would be costly and time-
consuming.

The CMOs with whom we currently work will also need to ensure and maintain quality (cGMP compliance, specifications,
shelf-life, expiry, in-process-control) throughout the production process of our clinical and commercial supplies. If we are
unable to ensure and maintain quality of our products candidates, we could be required to delay our ongoing clinical trials
which would be costly and time-consuming.

To mitigate the risks above, our relationships with CMOs are managed by internal personnel with extensive experience in
NCE pharmaceutical development and chemistry, manufacturing and controls, or CMC.

Competition

Biopharmaceutical product development is highly competitive and subject to rapid and significant technological
advancements. Our success is highly dependent upon our ability to in-license, acquire, develop and obtain regulatory
approval for new and innovative products on a cost-effective basis and to market them successfully. In doing so, we face
and will continue to face intense competition from a variety of businesses, including large, fully integrated, well-
established pharmaceutical companies who already possess a large share of the market, specialty pharmaceutical and
biopharmaceutical companies, academic institutions, government agencies and other private and public research institutions
in the European Union, United States and other jurisdictions.

With respect to OBE2109, there are no GnRH antagonists currently approved for the treatment of pain associated with
endometriosis or heavy menstrual bleeding associated with uterine fibroids. However, we are aware that AbbVie Inc.,
Myovant Sciences, Inc. and Astellas Pharma Inc. are developing GnRH antagonist product candidates for treatment of
symptoms associated with endometriosis or uterine fibroids. AbbVie submitted an NDA for elagolix for the treatment of
endometriosis in 2017 and was granted a priority review by the FDA. AbbVie expects the PDUFA date for the FDA to
complete its review will be in the second quarter of 2018. We also anticipate competing with GnRH agonists, including
Lupron (leuprolide acetate), marketed by AbbVie Inc. and Takeda Pharmaceuticals, Visanne, which is approved for the
treatment of endometriosis outside the United States and marketed by Bayer, ulipristal acetate, which is approved for the
treatment of moderate-to-severe symptoms of uterine fibroids outside the United States and marketed by Gedeon Richter in
Europe and other regions, and by Allergan in Canada. Allergan submitted an NDA for ulipristal acetate with the FDA in
2017, and expects a PDUFA date to occur in the first half of 2018. In addition, oral contraceptives and NSAIDs are
routinely used as a first-line therapy for treatment of symptoms associated with endometriosis and uterine fibroids and have
a meaningful success rate at mitigating the symptoms associated with these conditions.

With respect to nolasiban, there are no oxytocin receptor antagonists approved for use in connection with IVF. However,
we are aware that Ferring Pharmaceuticals Inc. has been developing barusiban, an oxytocin receptor antagonist, to be
administered subcutaneously, for use in connection with IVF. Ferring Pharmaceuticals’ atosiban, an oxytocin receptor
antagonist, to be administered by continuous intra-venous infusion, has been used in investigator initiated trials in
connection with IVF outside the United States.

ObsEva S.A. - Annual Report 2017

With respect to OBE022, we anticipate competing with atosiban, which has been approved to delay preterm birth outside of
the United States, as well as currently available calcium channel blockers, such as nifedipine or prostaglandin synthesis
inhibitors, such as NSAIDs. It is our understanding that GlaxoSmithKline may either terminate, partner or divest retosiban,
an oxytocin receptor antagonist, designed to delay preterm birth.

We may also compete with other companies acquiring and developing or marketing drug therapies or products for women’s
reproductive health diseases.

Many of the companies against which we are competing or against which we may compete in the future have significantly
greater financial resources and expertise in research and development, manufacturing, preclinical testing, conducting
clinical trials, obtaining regulatory approvals and marketing approved drugs than we do. Mergers and acquisitions in the
biopharmaceutical industry could result in even more resources being concentrated among a small number of our
competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through
collaborative arrangements with large and established companies. These third parties compete with us in recruiting and
retaining qualified scientific and management personnel, establishing clinical trial sites and patient registration for clinical
trials, as well as in acquiring technologies complementary to, or necessary for, our programs.

Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that
are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than OBE2109,
nolasiban or OBE022 or any other product candidate that we may develop. Our competitors also may obtain FDA or other
regulatory approval for their product candidates more rapidly than we may obtain approval for our product candidates,
which could result in our competitors establishing a strong market position before we are able to enter the market. Any new
product that competes with an approved product must demonstrate compelling advantages in efficacy, convenience,
tolerability and safety in order to overcome price competition and to be commercially successful.

In addition, established biopharmaceutical companies may invest heavily to accelerate discovery and development of novel
compounds or to in-license novel compounds that could make OBE2109, nolasiban, OBE022 or any of our future product
candidates less competitive.

Intellectual Property

We have filed numerous patent applications and have licensed numerous issued patents and patent applications pertaining
to our product candidates and methods of manufacture and clinical use. We strive to protect and enhance the proprietary
technology, inventions, and improvements that are commercially important to the development of our business by seeking,
maintaining and defending our intellectual property, whether developed internally or licensed from third parties. For
additional information regarding the license agreements to which we are a party, see the sections entitled “2013 License
Agreement with Merck Serono,” “2015 License Agreement with Merck Serono” and “License and Supply Agreement with
Kissei.” We also rely on trade secrets, know-how, continuing technological innovation and potential in-licensing
opportunities to develop, strengthen and maintain our proprietary position in the field of reproductive healthcare.
Additionally, we intend to rely on regulatory protection afforded through data exclusivity and market exclusivity, as well as
patent term extensions, where available.

As of December 31, 2017, our patent portfolio as it pertains to certain of our product candidates included:

•

two United States (U.S.) patents, projected to expire between 2034 and 2035, three U.S. patent applications,
which, if granted, project to expire between 2034 and 2035, as well as corresponding patents and patent
applications internationally, all the previous directed to nolasiban as a composition of matter or oral
formulation or crystal polymorph and uses of nolasiban in assisted reproductive technology and

one international (PCT) application, which, if granted in the U.S., projects to expire in 2037, directed to
nolasiban as a composition of matter and uses of nolasiban in assisted reproductive technology;

one PCT application, which, if granted in the U.S., projects to expire in 2037, directed to compositions of
matter containing OBE022 and uses of OBE022 for the treatment of preterm labor; and

two U.S. patent applications, which, if granted, project to expire in 2038, directed to uses of OBE2109 for the
treatment of endometriosis and uterine fibroids.

ObsEva S.A. - Annual Report 2017

Business Update

As of December 31, 2017, our in-licensed patent portfolio as it pertains to certain of our product candidates included:

•

one U.S. patent, projected to expire in 2023, as well as corresponding patents and patent applications
internationally, directed to nolasiban as a composition of matter and uses of nolasiban for the treatment of
preterm labor;

three U.S. patents, projected to expire between 2024 and 2036, as well as corresponding patents and patent
applications internationally, one U.S. patent application, which, if granted, projects to expire in 2036, and one
PCT application, which, if granted in the U.S., projects to expire in 2037, directed to OBE022 as a composition
of matter and uses of OBE022 for the treatment of preterm labor; and

three U.S. patents, projected to expire between 2030 and 2032, as well as corresponding patents and patent
applications internationally outside of specified Asian countries, and one U.S. patent application, which, if
granted, projects to expire in 2031, directed to OBE2109 as a composition of matter and uses of OBE2109 for
the treatment of sex hormone-dependent diseases.

The terms of individual patents may vary based on the countries in which they are obtained. Generally, patents issued for
applications filed in the United States are effective for 20 years from the earliest effective non-provisional filing date in the
absence, for example, of a terminal disclaimer shortening the term of the patent or patent term adjustment increasing the
term of the 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 FDA regulatory review periods. 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
patents outside of the United States varies in accordance with provisions of applicable local law, but typically is also 20
years from the earliest effective non-provisional filing date.

In addition to patents and patent applications that we own and license, we rely on trade secrets and know-how to develop
and maintain our competitive position. However, trade secrets can be difficult to protect. We seek to protect our proprietary
technology and processes, and obtain and maintain ownership of certain technologies, in part, through confidentiality
agreements and invention assignment agreements with our employees, consultants, scientific advisors, contractors, and
commercial partners.

Our future commercial success depends, in part, 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 valid enforceable patents and
proprietary rights of third parties. Our ability to stop third parties from making, using, selling, offering to sell, or importing
our products may depend on the extent to which we have rights under valid and enforceable patents or trade secrets that
cover these activities. With respect to our owned and licensed intellectual property, we cannot be sure that patents will
issue from any of the pending patent applications to which we own or license rights or from any patent applications that we
or our licensors may file in the future, nor can we be sure that any of our licensed patents or any patents that may be issued
in the future to us or to our licensors will be commercially useful in protecting our product candidates and methods of using
or manufacturing the same. Moreover, we may be unable to obtain patent protection for certain aspects of our product
candidates generally, as well as with respect to certain indications. See the section entitled “Risk Factors—Risks Related to
Our Intellectual Property” for a more comprehensive description of risks related to our intellectual property.

2013 License Agreement with Merck Serono

In August 2013, we entered into a license agreement, or the 2013 license agreement, with Merck Serono, pursuant to which
we received a worldwide exclusive license to develop, manufacture and commercialize compounds covered by the licensed
patent rights, including nolasiban, which we are developing for the treatment of conditions associated with ART. In
consideration for the license, we issued 914,069 Series A preferred shares to Merck Serono at the time of our Series A
financing, which had a fair-value of $4.9 million. With respect to any products we commercialize under the 2013 license
agreement, we have agreed to pay Merck Serono quarterly royalties based on our annual net sales of each product at a high-
single-digit percentage of annual net sales, subject to specified reductions, until the later of the date that all of the patent
rights for that product have expired, as determined on a country-by-country and product-by-product basis, or ten years from
the first commercial sale of such product on a country-by-country and product-by-product basis.

We are solely responsible for the development and commercialization of the product candidates licensed under the 2013
license agreement. Merck Serono has the first right to maintain, prosecute, and even enforce the licensed patent rights. The

ObsEva S.A. - Annual Report 2017

Business Update

2013 license agreement expires on the date of expiration of all royalty obligations, at which time our license becomes fully
paid-up, irrevocable, and perpetual. Either party may terminate the 2013 license agreement earlier for an uncured material
breach, subject to notice requirements and specified exceptions. Merck may terminate the 2013 license agreement if we or
any of our affiliates or sublicensees challenge the licensed patent rights or in the event of our bankruptcy if we do not
obtain a sublicensee within two years thereafter. We may also terminate the 2013 license agreement without cause at any
time upon advance written notice to Merck Serono. Upon any termination, all license granted to us under the 2013 license
agreement terminate.

2015 License Agreement with Merck Serono

In June 2015, we entered into a second license agreement with Merck Serono, or the 2015 license agreement, which we
amended in July 2016, pursuant to which we received a worldwide exclusive license to develop, manufacture and
commercialize compounds covered by the licensed patent rights, including OBE022, which we are developing for the
treatment of preterm labor in weeks 24 to 34 of pregnancy. In consideration for the license, we agreed to issue 325,000
Series A preferred shares to Merck Serono upon the initiation of a Phase 1 clinical trial for a licensed product. With respect
to any products we commercialize under the 2015 license agreement, we have agreed to pay Merck Serono quarterly
royalties based on our annual net sales of each product at a mid-single-digit percentage of annual net sales, subject to
specified reductions, until the later of the date that all of the patent rights for that product have expired, as determined on a
country-by-country and product-by-product basis or ten years from the first commercial sale of such product on a country-
by-country and product-by-product basis.

We are solely responsible for the development and commercialization of the product candidates licensed under the 2015
license agreement. Merck Serono has the first right to maintain, prosecute, and even enforce the licensed patent rights. The
2015 license agreement expires on the date of expiration of all royalty obligations, at which time our license becomes fully
paid-up, irrevocable and perpetual. Either party may terminate the 2015 license agreement earlier for an uncured material
breach, subject to notice requirements and specified exceptions. Merck may terminate the 2015 license agreement if we or
any of our affiliates or sublicensees challenge the licensed patent rights or in the event of our bankruptcy if we do not
obtain a sublicensee within two years thereafter. We may also terminate the agreement without cause at any time upon
advance written notice to Merck Serono. Upon any termination, all license granted to us under the 2015 license agreement
terminate.

License and Supply Agreement with Kissei

In November 2015, we entered into a license and supply agreement, or the Kissei license and supply agreement, with
Kissei. Pursuant to the Kissei license and supply agreement we received an exclusive license to develop, manufacture and
commercialize products, or the Product, containing the compounds which is a specified GnRH antagonist and covered by
certain licensed patent rights, or the Compound, throughout the world except for specified Asian countries and we arranged
to exclusively acquire from Kissei the material necessary to produce OBE2109. Under the Kissei license and supply
agreement, we are developing OBE2109 for the treatment of heavy menstrual bleeding associated with uterine fibroids and
pain associated with endometriosis. The agreement also establishes a joint development committee, and upon the filing of
regulatory approval, a joint marketing committee, each of which shall be composed of an equal number of representatives
for each party, which will exchange information and monitor progress in the development and marketing of the Product,
respectively. We must use commercially reasonable efforts to develop, manufacture and commercialize the Compound and
the Product. We and Kissei will share development data and regulatory filings from our respective territories with one
another. Further, we granted Kissei an exclusive license under any of our know-how and patents related to inventions or
improvements resulting from our activities under the Kissei license and supply agreement, for Kissei to use in exploiting
the Compound and the Product in their retained territory.

In consideration for the license, we made an initial $10.0 million upfront payment. We also made a payment of $5.0 million
to Kissei in 2017 related to our commencement of the PRIMROSE Phase 3 clinical trials in the uterine fibroid indication.
In addition, we have agreed to make additional aggregate milestone payments of up to $58.0 million upon the achievement
of specified developmental milestones, such as the initiation of clinical trials and receipt of regulatory approvals. With
respect to any Product we commercialize under the Kissei license and supply agreement, we have agreed to make
additional aggregate milestone payments of up to $125.0 million to Kissei upon the achievement of specified commercial
milestones.

ObsEva S.A. - Annual Report 2017

Business Update

Pursuant to the Kissei license and supply agreement, we have agreed to exclusively purchase the active pharmaceutical
ingredient for OBE2109 from Kissei. During the development stage, we are obligated to pay Kissei a specified supply
price. Following the first commercial sale of licensed product, we are obligated to pay Kissei a royalty payment in the low
twenty percent range as a percentage of net sales, which includes payment for Kissei’s supply of the active pharmaceutical
ingredient until the latest of the date that the valid claim of a patent for the Product has expired, the expiration of our
regulatory exclusivity period or 15 years from the first commercial sale of such product on a country-by-country and
product-by-product basis. During the term, we are restricted from developing, marketing and selling GnRH agonists and
GnRH antagonists other than the Compound to the extent allowed by applicable laws.

We are solely responsible, at our expense, for the development and commercialization of the Product candidates licensed
under the Kissei license and supply agreement in the licensed territory. Kissei has the responsibility to maintain and
prosecute the licensed patent rights in the licensed territory and we have the right to enforce any of them in the event that
Kissei abandons it. The Kissei license and supply agreement terminates on the date of expiration of all royalty obligations,
unless we elect to continue to purchase the Compound from Kissei after the expiration of all royalty obligations. Either
party may terminate the Kissei license and supply agreement earlier for an uncured breach, subject to notice requirements
and specified exceptions, including that Kissei has the option to convert the exclusive licenses granted to us to non-
exclusive if we breach the agreement and fail to cure within a specified time period. We may also terminate the agreement
for scientific, commercial, strategic or intellectual property reasons at any time upon advance written notice to Kissei.
Kissei may also terminate the agreement if we do not fulfill certain development-related obligations for a specified period
of time, or if, in connection with a change of control by us, we do not fulfill certain diligence obligations for a specified
period of time. Further, under the terms of the Kissei license and supply agreement, Kissei is obligated to have a backup
supplier based on the pharmaceutical industry standard. We may only gain the right to obtain an alternative source of the
supply of OBE2109 upon Kissei failing to deliver a substantial percentage of the requested supply, delivering the supply
late or delivering the supply of OBE2109 in nonconforming manner; provided that Kissei has a specified period of time to
cure any of these defects. In the event that Kissei failed to deliver a substantial percentage of requested supply of
OBE2109, we may gain the right to obtain an alternative source of supply. Further, we and Kissei are each obligated to
maintain a specified percentage of supply in excess of the estimate for yearly requirements that we submit to Kissei.

Government Regulation
FDA Drug Approval Process

In the United States, pharmaceutical products are subject to extensive regulation by the FDA. The Federal Food, Drug, and
Cosmetic Act, or FDCA, and other federal and state statutes and regulations, govern, among other things, the research,
development, testing, manufacture, storage, recordkeeping, approval, labeling, promotion and marketing, distribution, post-
approval monitoring and reporting, sampling and import and export of pharmaceutical products. To obtain regulatory
approvals in the United States and in foreign countries, and subsequently comply with applicable statutes and regulations,
we will need to spend substantial time and financial resources.

Approval Process

The FDA must approve any new drug or a drug with certain changes to a previously approved drug before a company can
market it in the United States. Failure to comply with applicable U.S. requirements may subject a company to a variety of
administrative or judicial sanctions, such as FDA refusal to approve pending applications, warning or untitled letters,
clinical holds, withdrawal of an approval, product recalls, product seizures, total or partial suspension of production or
distribution, injunctions, fines, refusals of government contracts, restitution, disgorgement, civil penalties or criminal
prosecution.

The steps required before a drug may be marketed in the United States generally include the following:

•

completion of extensive preclinical laboratory tests, animal studies and CMC studies, all performed in
accordance with the FDA’s Good Laboratory Practice, or GLP, regulations;

submission to the FDA of an IND application for human clinical testing, which must become effective before
human clinical trials may begin. The sponsor must update the IND annually;

approval of the study by an IRB or ethics committee at each site before the study begins;

ObsEva S.A. - Annual Report 2017

Business Update

•

performance of adequate and well-controlled human clinical trials in accordance with good clinical practice, or
GCP, requirements to establish the safety and efficacy of the drug for each proposed indication to the FDA’s
satisfaction;

submission to the FDA of an NDA after completion of all clinical trials;

potential review of the drug application by an FDA advisory committee, if applicable;

satisfactory completion of an FDA inspection of the manufacturing facility or facilities at which the products is
produced to assess compliance with cGMP regulations and to assure that the facilities, methods and controls
are adequate to preserve the drug’s identity; and

FDA review and approval of the NDA prior to any commercial marketing or sale of the drug in the United
States.

Satisfaction of FDA pre-market approval requirements typically takes many years and the actual time required may vary
substantially based upon the type, complexity and novelty of the product or disease.

Preclinical tests include laboratory evaluation of product chemistry, formulation and toxicity, as well as animal trials to
assess the characteristics and potential safety and efficacy of the product. The conduct of the preclinical tests must comply
with federal regulations and requirements, including GLP. The company submits the results of the preclinical testing,
together with manufacturing information, analytical data and any available clinical data or literature to the FDA as part of
an IND along with other information, including information about product CMC and a proposed clinical trial protocol.
Long term preclinical tests, such as animal tests of reproductive toxicity and carcinogenicity, may continue after submitting
the initial IND.

The FDA requires a 30-day waiting period after the submission of each IND before the company can begin clinical testing
in humans. The FDA may, within the 30-day time period, raise concerns or questions relating to one or more proposed
clinical trials and place the study on a clinical hold. In such a case, the company and the FDA must resolve any outstanding
concerns before the company may begin the clinical trial. Accordingly, the submission of an IND may or may not be
sufficient to permit the sponsor to start a clinical trial. If, following the 30-day period, the FDA does not raise any concerns
regarding the IND submission, the company may begin clinical testing under the IND. The company must also make a
separate submission to an existing IND for each successive clinical trial conducted during drug development.

ObsEva S.A. - Annual Report 2017

Business Update

Clinical Trials

Clinical trials involve administering the investigational new drug to healthy volunteers or patient trials under the
supervision of a qualified investigator. The company must conduct clinical trials:

•

in compliance with federal regulations;

in compliance with GCP, an international standard meant to protect the rights and health of patients and to
define the roles of clinical trial sponsors, administrators, and monitors; as well as

under protocols detailing the objectives of the trial, the safety monitoring parameters, and the effectiveness
criteria to be evaluated.

The FDA may order the temporary, or permanent, discontinuation of a clinical trial at any time, or impose other sanctions,
if it believes that the sponsor is not conducting the clinical trial in accordance with FDA requirements or presents an
unacceptable risk to the clinical trial patients. The sponsor must also submit the study protocol, any amendments to
protocols and informed consent information for patients in clinical trials to an IRB for approval at each site at which the
clinical trial will be conducted. An IRB may halt the clinical trial, either temporarily or permanently, for failure to comply
with the IRB’s requirements, or may impose other conditions. Information about certain clinical trials and their results must
be also submitted within specific timeframes to the National Institutes of Health, or NIH, for public dissemination on their
www.clinicaltrials.gov website.

Companies generally divide the clinical investigation of a drug into three or four phases. While companies usually conduct
these phases sequentially, they are sometimes overlapped or combined.

•

Phase 1. These trials typically evaluate the safety, dosage tolerance, metabolism and pharmacologic actions of
the investigational new drug in humans, the side effects associated with increasing doses, and if possible, gain
early evidence on effectiveness. Other Phase 1 or clinical pharmacology studies generally evaluate the drug for
potential DDI, cardiovascular safety and special population interactions. These studies, if needed, are to be
conducted prior to NDA submission but may be conducted in parallel to Phase 2 and Phase 3.

Phase 2. The drug is administered to a limited patient population to evaluate dosage tolerance and optimal
dosage, identify possible adverse side effects and safety risks, and preliminarily evaluate efficacy. Phase 2
trials may be denoted as Phase 2a, wherein initial dose-response relationship is explored, and Phase 2b,
wherein dose ranging and proof-of-concept is targeted.

Phase 3. The drug is administered to an expanded patient population, generally at geographically dispersed
clinical trial sites, in well-controlled clinical trials to generate enough data to statistically evaluate dosage,
clinical effectiveness and safety, to establish the overall benefit-risk relationship of the investigational drug,
and to provide an adequate basis for labeling and product approval.

Phase 4. In some cases, the FDA may condition approval of an NDA for a drug on the company’s agreement to
conduct additional clinical trials after approval. In other cases, a sponsor may voluntarily conduct additional
clinical trials after approval to gain more information about the drug. Companies typically refer to such post-
approval trials as Phase 4 clinical trials.

The FDA, the IRB, or the clinical trial sponsor may suspend or terminate a clinical trial at any time on various grounds,
including a finding that the research patients are being exposed to an unacceptable health risk. Similarly, an IRB can
suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in accordance
with the IRB’s requirements or if the drug has been associated with unexpected serious harm to patients. Additionally, an
independent group of qualified experts organized by the clinical trial sponsor, known as a data safety monitoring board or
committee, may oversee some clinical trials. This group provides authorization for whether or not a trial may move forward
at designated check points based on access to certain data from the trial. We may also suspend or terminate a clinical trial
based on evolving business objectives and the competitive climate.

Submission of an NDA

After we complete the required preclinical, CMC and clinical testing, we can prepare and submit an NDA to the FDA,
which must approve the NDA before we can start marketing the drug in the United States. An NDA must include all
relevant data available from pertinent preclinical studies and clinical trials, including negative or ambiguous results as well
as positive findings, together with detailed information relating to the drug’s chemistry, manufacturing, controls, and

ObsEva S.A. - Annual Report 2017

Business Update

proposed labeling, among other things. Data can come from company-sponsored clinical trials on a drug, or from a number
of alternative sources, including studies initiated by investigators. To support marketing authorization, the data we submit
must be sufficient in quality and quantity to establish the safety and effectiveness of the investigational drug to the FDA’s
satisfaction.

The cost of preparing and submitting an NDA is substantial. The submission of most NDAs is additionally subject to a
substantial application user fee, and the sponsor under an approved NDA is also subject to annual program user fees. The
FDA typically increases these fees annually.

The FDA has 60 days from its receipt of an NDA to determine whether it will accept the application for filing based on the
agency’s threshold determination that the application is sufficiently complete to permit substantive review. The FDA may
request additional information rather than accept an NDA for filing. In this event, the application must be resubmitted with
the additional information. The resubmitted application is also 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 the drug is safe and effective and whether the facility in which it is manufactured,
processed, packaged or held meets standards designed to assure the product’s continued safety, quality and purity. Once the
FDA accepts the filing, the FDA begins an in-depth review. The FDA has agreed to certain performance goals in the review
of NDAs. Under the Prescription Drug User Fee Act, the FDA has a goal of responding to standard review NDAs within
ten months after the 60-day filing review period, but this timeframe is often extended. The FDA reviews most applications
for standard review drugs within ten to 12 months and most applications for priority review drugs within six to eight
months. Priority review can be applied to drugs that the FDA determines offer major advances in treatment, or provide a
treatment where no adequate therapy exists.

In addition, under the Pediatric Research Equity Act of 2003, as amended and reauthorized, certain NDAs or supplements
to an NDA must contain data that are adequate 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, on its own initiative or at the request of the applicant, grant
deferrals for submission of some or all pediatric data until after approval of the product for use in adults, or full or partial
waivers from the pediatric data requirements.

The FDA may also refer applications for novel drug products, or drug products that present difficult questions of safety or
efficacy, to an advisory committee. This is typically a panel that includes clinicians and other experts that will review,
evaluate, and recommend whether the FDA should approve the application. The FDA is not bound by the recommendation
of an advisory committee, but it generally follows such recommendations. Before approving an NDA, the FDA will
typically inspect one or more clinical sites to assure compliance with GCP, and will inspect the facility or the facilities at
which the drug is manufactured. The FDA will not approve the product unless compliance with cGMP is satisfactory and
the NDA contains data that provide evidence that the drug is safe and effective in the indication studied.

The FDA’s Decision on an NDA

After the FDA evaluates the NDA and all related information, including the advisory committee recommendation, if any,
and inspection reports regarding the manufacturing facilities and clinical trial sites, it issues either an approval letter or a
complete response letter. A complete response letter indicates that the FDA has completed its review of the application, and
the agency has determined that it will not approve the application in its present form. A complete response letter generally
outlines the deficiencies in the submission and may require substantial additional clinical data or other significant,
expensive, and time-consuming requirements related to clinical trials, preclinical studies or manufacturing. The FDA has
committed to reviewing resubmissions of the NDA addressing such deficiencies in two or six months, depending on the
type of information included. Even with the submission of this additional information, the FDA may ultimately decide that
the NDA does not satisfy the criteria for approval. The government may establish additional requirements, including those
resulting from new legislation, or the FDA’s policies may change, which could delay or prevent regulatory approval of our
drugs under development.

An approval letter authorizes commercial marketing of the drug with specific prescribing information for specific
indications. As a condition of NDA approval, the FDA may require an REMS, to help ensure that the benefits of the drug
outweigh the potential risks. REMS can include medication guides, communication plans for healthcare professionals,
special training or certification for prescribing or dispensing, dispensing only under certain circumstances, special
monitoring, and the use of patient registries. The requirement for REMS can materially affect the potential market and

ObsEva S.A. - Annual Report 2017

Business Update

profitability of the drug. Moreover, the FDA may condition approval on substantial post-approval testing and surveillance
to monitor the drug’s safety or efficacy.

Changes to some of the conditions established in an approved application, including changes in indications, labeling, or
manufacturing processes or facilities, require submission and FDA approval of a new NDA or NDA supplement before we
can implement the change. An NDA supplement for a new indication typically requires clinical data similar to that in the
original application, and the FDA uses the same procedures and actions in reviewing NDA supplements as it does in
reviewing new NDAs. As with new NDAs, the FDA often significantly extends the review process with requests for
additional information or clarification.

Post-approval Requirements

The FDA regulates products that are manufactured or distributed pursuant to FDA approvals and has specific requirements
pertaining to recordkeeping, periodic reporting, product sampling and distribution, advertising and promotion and reporting
of adverse experiences with the product. After approval, the FDA must provide review and approval for most changes to
the approved product, such as adding new indications or other labeling claims. There also are continuing, annual user fee
requirements for any marketed products and the establishments who manufacture our products, as well as new application
fees for supplemental applications with clinical data.

In some cases, the FDA may condition approval of an NDA for a product on the sponsor’s agreement to conduct additional
clinical trials after approval. In other cases, a sponsor may voluntarily conduct additional clinical trials after approval to
gain more information about the product. Such post-approval trials are typically referred to as Phase 4 clinical trials.

In addition, drug manufacturers and other entities involved in the manufacture and distribution of approved drugs are
required to register their establishments with the FDA and state agencies, and are subject to periodic unannounced
inspections by the FDA and state agencies for compliance with cGMP requirements. There are strict regulations regarding
changes to the manufacturing process, and, depending on the significance of the change, it may require prior FDA approval
before we can implement it. FDA regulations also require investigation and correction of any deviations from cGMP and
impose reporting and documentation requirements upon us and any third-party manufacturers that we may decide to use.
Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to
maintain compliance with cGMP and other aspects of regulatory compliance.

The FDA may withdraw approval if a company does not comply with regulatory requirements and maintain standards or if
problems occur after the product reaches the market. If a company or the FDA discovers previously unknown problems
with a product, including adverse events of unanticipated severity or frequency, issues with manufacturing processes, or the
company’s failure to comply with regulatory requirements, the FDA may revise the approved labeling to add new safety
information; impose post-marketing trials or other clinical trials to assess new safety risks; or impose distribution or other
restrictions under a REMS program. Other potential consequences may include:

•

restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the
market or product recalls;

fines, warning letters or holds on post-approval clinical trials;

the FDA refusing to approve pending NDAs or supplements to approved NDAs, or suspending or revoking of
product license approvals;

product seizure or detention, or refusal to permit the import or export of products; or

injunctions or the imposition of civil or criminal penalties.

The FDA strictly regulates marketing, labeling, advertising, and promotion of products that are placed on the market.
Products may be promoted only for the approved indications and in accordance with the provisions of the approved label.
The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses. We
could be subject to significant liability if we violated these laws and regulations.

Healthcare Reform

In the United States, the European Union and foreign jurisdictions, the legislative landscape continues to evolve. There
have been a number of legislative and regulatory changes to the healthcare system that could affect our future results of
operations. In particular, there have been and continue to be a number of initiatives at the United States federal and state
levels that seek to reduce healthcare costs. In March 2010, the Patient Protection and Affordable Care Act, as amended by
the Health Care and Education Reconciliation Act, or collectively, the ACA, was enacted, which includes measures that
have significantly changed health care financing by both governmental and private insurers. The provisions of the ACA of
importance to the pharmaceutical and biotechnology industry are, among others, the following:

•

an annual, nondeductible fee on any entity that manufactures or imports certain branded prescription drugs
agents and biologic agents, which is apportioned among these entities according to their market share in certain
government healthcare programs;

an increase in the rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and
13% of the average manufacturer price for branded and generic drugs, respectively;

a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 50% (and
70% starting January 1, 2019) point-of-sale discounts to negotiated prices of applicable brand drugs to eligible
beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be
covered under Medicare Part D;

extension of manufacturers’ Medicaid rebate liability to covered drugs dispensed to individuals who are
enrolled in Medicaid managed care organizations, unless the drug is subject to discounts under the 340B drug
discount program;

calculated for drugs that are inhaled, infused, instilled, implanted or injected;

expansion of eligibility criteria for Medicaid programs by, among other things, allowing states to offer
Medicaid coverage to additional individuals and by adding new mandatory eligibility categories for certain
individuals with income at or below 133% of the federal poverty level, thereby potentially increasing
manufacturers’ Medicaid rebate liability;

expansion of the entities eligible for discounts under the Public Health Service pharmaceutical pricing
program;

new requirements under the federal Physician Payments Sunshine Act for drug manufacturers to report
information related to payments and other transfers of value made to physicians and teaching hospitals as well
as ownership or investment interests held by physicians and their immediate family members;

a new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative
clinical effectiveness research, along with funding for such research; and

establishment of a Center for Medicare and Medicaid Innovation at the CMS to test innovative payment and
service delivery models to lower Medicare and Medicaid spending, potentially including prescription drug
spending.

There have been judicial and Congressional challenges to certain aspects of the ACA, as well as recent efforts by the
Trump administration to repeal or replace certain aspects of the ACA. Since January 2017, President Trump has signed two
Executive Orders and other directives designed to delay the implementation of certain provisions of the ACA or otherwise
circumvent some of the requirements for health insurance mandated by the ACA. Concurrently, Congress has considered
legislation that would repeal or repeal and replace all or part of the ACA. While Congress has not passed comprehensive
repeal legislation, two bills affecting the implementation of certain taxes under the ACA have been signed into law. The
Tax Cuts and Jobs Act of 2017 includes a provision repealing, effective January 1, 2019, the tax-based shared
responsibility payment imposed by the ACA on certain individuals who fail to maintain qualifying health coverage for all
or part of a year that is commonly referred to as the “individual mandate”. Additionally, on January 22, 2018, President
Trump signed a continuing resolution on appropriations for fiscal year 2018 that delayed the implementation of certain
ACA-mandated fees, including the so-called “Cadillac” tax on certain high cost employer-sponsored insurance plans, the
annual fee imposed on certain health insurance providers based on market share, and the medical device excise tax on non-
exempt medical devices. Further, the Bipartisan Budget Act of 2018, or the BBA, among other things, amends the ACA,

effective January 1, 2019, to close the coverage gap in most Medicare drug plans, commonly referred to as the “donut
hole”. Congress could consider other legislation to repeal or replace certain elements of the ACA. At this time, the full
effect that the ACA would have on our business remains unclear.

In addition, other federal health reform measures have been proposed and adopted in the United States since the ACA was
enacted. For example, as a result of the Budget Control Act of 2011, providers are subject to Medicare payment reductions
of 2% per fiscal year, which, due to subsequent legislation, including the BBA, will remain in effect through 2027 unless
additional Congressional action is taken.

Further, the American Taxpayer Relief Act of 2012 reduced Medicare payments to several providers and increased the
statute of limitations period for the government to recover overpayments from providers from three to five years. More
recently, there has been heightened governmental scrutiny recently over the manner in which manufacturers set prices for
their marketed products, which have resulted in several recent Congressional inquiries and proposed and enacted federal
and state legislation designed to, among other things, bring more transparency to product pricing, review the relationship
between pricing and manufacturer patient programs, reduce the cost of drugs under Medicare and reform government
program reimbursement methodologies for products.

At the federal level, the Trump administration’s budget proposal for fiscal year 2019 contains further drug price control
measures that could be enacted during the 2019 budget process or in other future legislation, including, for example,
measures to permit Medicare Part D plans to negotiate the price of certain drugs under Medicare Part B, to allow some
states to negotiate drug prices under Medicaid, and to eliminate cost sharing for generic drugs for low-income patients.
While any proposed measures will require authorization through additional legislation to become effective, Congress and
the Trump administration have each indicated that it will continue to seek new legislative and/or administrative measures to
control drug costs. At the state level, individual states in the United States are increasingly passing legislation and
implementing regulations designed to control pharmaceutical and biological product pricing, including price or patient
reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency
measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. In addition,
regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what
pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs.
These measures could reduce the ultimate demand for our products or put pressure on our product pricing.

Coverage, Reimbursement and Pricing

Significant uncertainty exists as to the coverage and reimbursement status of any products for which we may obtain
regulatory approval. In the United States and markets in other countries, sales of any products for which we receive
regulatory approval for commercial sale will depend, in part, on the availability of coverage and the adequacy of
reimbursement from third-party payors. Third-party payors include government authorities, managed care organizations,
private health insurers and other organizations. The process for determining whether a third-party payor will provide
coverage for a product may be separate from the process for setting the reimbursement rate that the payor will pay for the
product. Third-party payors may limit coverage to specific products on an approved list, or formulary, which might not
include all of the FDA-approved products for a particular indication. Moreover, a third-party payor’s decision to provide
coverage for a product does not imply that an adequate reimbursement rate will be approved. For example, the payor’s
reimbursement payment rate may not be adequate or may require co-payments that patients find unacceptably high.
Additionally, coverage and reimbursement for products can differ significantly from payor to payor. The Medicare and
Medicaid programs increasingly are used as models for how private payors and other governmental payors develop their
coverage and reimbursement policies for drugs and biologics. However, one third-party payor’s decision to cover a
particular product does not ensure that other payors will also provide coverage for the product, or will provide coverage at
an adequate reimbursement rate. Adequate third-party reimbursement may not be available to enable us to maintain price
levels sufficient to realize an appropriate return on our investment in product development. Further, some third-party
payors may require pre-approval of coverage for new or innovative devices or drug therapies before they provide
reimbursement for use of such therapies.

ObsEva S.A. - Annual Report 2017

Business Update

Third-party payors are increasingly challenging the price and examining the medical necessity and cost-effectiveness of
products and services, in addition to their safety and efficacy. To obtain coverage and reimbursement for any product that
might be approved for sale, we may need to conduct expensive pharmacoeconomic studies to demonstrate the medical
necessity and cost-effectiveness of our product. These studies will be in addition to the studies required to obtain regulatory
approvals. If third-party payors do not consider a product to be cost-effective compared to other available therapies, they
may not cover the product after approval as a benefit under their plans or, if they do, the level of payment may not be
sufficient to allow a company to sell its products at a profit. Thus, obtaining and maintaining reimbursement status is time-
consuming and costly.

The U.S. government, state legislatures and foreign governments have shown significant interest in implementing cost
containment programs to limit the growth of government-paid health care costs, including price controls, restrictions on
reimbursement and requirements for substitution of generic products for branded prescription products. By way of
example, the ACA contains provisions that may reduce the profitability of products, including, for example, increased
rebates for products sold to Medicaid programs, extension of Medicaid rebates to Medicaid managed care plans, mandatory
discounts for certain Medicare Part D beneficiaries and annual fees based on pharmaceutical companies’ share of sales to
federal health care programs. CMS may develop new payment and delivery models, such as bundled payment models. For
example, the HHS set a goal of moving 50% of Medicare payments to alternative payment models tied to the quality or
value of services by the end of 2018. Adoption of government controls and measures, and tightening of restrictive policies
in jurisdictions with existing controls and measures, could limit payments for our products.

In the European Community, governments influence the price of products through their pricing and reimbursement rules
and control of national health care systems that fund a large part of the cost of those products to consumers. Some
jurisdictions operate positive and negative list systems under which products may only be marketed once a reimbursement
price has been agreed to by the government. To obtain reimbursement or pricing approval, some of these countries may
require the completion of clinical trials that compare the cost effectiveness of a particular product candidate to currently
available therapies. Other member states allow companies to fix their own prices for medicines, but monitor and control
company profits. The downward pressure on health care costs in general, particularly prescription products, has become
very intense. As a result, increasingly high barriers are being erected to the entry of new products. In addition, in some
countries, cross border imports from low-priced markets exert a commercial pressure on pricing within a country.

The marketability of any products for which we receive regulatory approval for commercial sale may suffer if the
government and third-party payors fail to provide adequate coverage and reimbursement. In addition, the focus on cost
containment measures in the United States and other countries has increased and we expect will continue to increase the
pressure on pharmaceutical pricing. Coverage policies and third-party reimbursement rates may change at any time. Even if
we attain favorable coverage and reimbursement status for one or more products for which we receive regulatory approval,
less favorable coverage policies and reimbursement rates may be implemented in the future.

Sales and Marketing

Numerous regulatory authorities in addition to the FDA, including, in the United States, the Centers for Medicare &
Medicaid Services, other divisions of the HHS, the U.S. Department of Justice, and similar foreign, state, and local
government authorities, regulate sales, promotion and other activities following product approval. As described above, the
FDA regulates all advertising and promotion activities for products under its jurisdiction both prior to and after approval.
Only those claims relating to safety and efficacy that the FDA has approved may be used in labeling. Physicians may
prescribe legally available products for uses that are not described in the product’s labeling and that differ from those we
tested and the FDA approved. Such off-label uses are common across medical specialties, and often reflect a physician’s
belief that the off-label use is the best treatment for the patients. The FDA does not regulate the behavior of physicians in
their choice of treatments, but FDA regulations do impose stringent restrictions on manufacturers’ communications
regarding off-label uses. If we do not comply with applicable FDA requirements we may face adverse publicity,
enforcement action by the FDA, corrective advertising, consent decrees and the full range of civil and criminal penalties
available to the FDA. Promotion of off-label uses of products can also implicate the false claims laws described below.

ObsEva S.A. - Annual Report 2017

Business Update

In the United States, clinical research, sales, marketing and scientific/educational programs must also comply with various
federal and state laws pertaining to healthcare “fraud and abuse,” including anti-kickback laws and false claims laws. Anti-
kickback laws including, without limitation, the federal Anti-Kickback Statute that applies to items and services
reimbursable under governmental healthcare programs such as Medicare and Medicaid, makes it illegal for a prescription
drug manufacturer to solicit, offer, receive, or pay any remuneration in exchange for, or to induce, the referral of business,
including the purchase or prescription of a particular product. Due to the breadth of the statutory provisions, limited
statutory exceptions and regulatory safe harbors, and the scarcity of guidance in the form of regulations, agency advisory
opinions, sub-regulatory guidance and judicial decisions addressing industry practices, it is possible that our practices
might be challenged under the federal Anti-Kickback Statute or similar laws. Moreover, recent healthcare reform
legislation has strengthened these laws. For example, the ACA, among other things, amends the intent requirement of the
federal Anti-Kickback Statute and criminal healthcare fraud statutes to clarify that a person or entity does not need to have
actual knowledge of this statute or specific intent to violate it in order to have committed a violation. In addition, the ACA
clarifies that the government may assert that a claim that includes items or services resulting from a violation of the federal
Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act. In addition,
the U.S. federal government and private individuals, on behalf of the U.S. federal government, can bring similar actions
under the federal civil False Claims Act. False claims laws, including, without limitation, the federal civil False Claims
Act, prohibit anyone from knowingly and willingly presenting, or causing to be presented for payment, to third-party
payors (including Medicare and Medicaid) claims for reimbursed products or services that are false or fraudulent, claims
for items or services not provided as claimed, or claims for medically unnecessary items or services. Our activities relating
to the sale and marketing of our products may be subject to scrutiny under these laws, as well as civil monetary penalties
laws and the criminal healthcare fraud provisions enacted as part of HIPAA. Violations of fraud and abuse laws may be
punishable by criminal and civil sanctions, including fines and civil monetary penalties, the possibility of exclusion from
federal healthcare programs (including Medicare and Medicaid), disgorgement, individual imprisonment, and corporate
integrity agreements, which impose, among other things, rigorous operational and monitoring requirements on companies.
Similar sanctions and penalties, as well as imprisonment, also can be imposed upon executive officers and employees,
including criminal sanctions against executive officers under the so-called “responsible corporate officer” doctrine, even in
situations where the executive officer did not intend to violate the law and was unaware of any wrongdoing.

Given the significant penalties and fines that can be imposed on companies and individuals if convicted, allegations of such
violations often result in settlements even if the company or individual being investigated admits no wrongdoing.
Settlements often include significant civil sanctions, including fines and civil monetary penalties, and corporate integrity
agreements. If the government were to allege or convict us or our executive officers of violating these laws, our business
could be harmed. Our activities could be subject to challenge for the reasons discussed above and due to the broad scope of
these laws and the increasing attention being given to them by law enforcement authorities. Other healthcare laws that may
affect our ability to operate include HIPAA, as amended by HITECH, which governs the conduct of certain electronic
healthcare transactions and protects the security and privacy of protected health information; and the federal Physician
Payments Sunshine Act, which requires certain manufacturers of products, devices, biologics, and medical supplies to
report annually to HHS information related to payments and other transfers of value to physicians and teaching hospitals,
and ownership and investment interests held by physicians and their immediate family members.

Further, there are an increasing number of state laws that affect our business operations. Some state and local laws require
manufacturers to make reports to on pricing and marketing information and impose registration requirements on
salespersons within the jurisdiction. Other state laws require pharmaceutical companies to comply with the pharmaceutical
industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the U.S. federal
government, or otherwise restrict payments that may be made to healthcare providers and other potential referral sources.
Some states maintain anti-kickback and false claims laws that apply to claims involving healthcare items or services
reimbursed by any third-party payor, including private insurers. We may also be subject to state laws governing the privacy
and security of health information in certain circumstances, many of which differ from each other in significant ways and
often are not preempted by HIPAA, thus complicating compliance efforts. Many of these state laws contain ambiguities as
to what is required to comply with the laws. Given the lack of clarity in laws and their implementation, our reporting
actions could be subject to the penalty provisions of the pertinent state authorities. Ensuring that our internal operations and
future business arrangements with third parties comply with applicable healthcare laws and regulations could involve
substantial costs.

Similar rigid restrictions are imposed on the promotion and marketing of products in the European Union and other
countries. Even in those countries where we may not be directly responsible for the promotion and marketing of our

ObsEva S.A. - Annual Report 2017

Business Update

products, if our potential international distribution partners engage in inappropriate activity it can have adverse implications
for us.

Foreign Regulation

In order to market any product outside of the United States, we would need to comply with numerous and varying
regulatory requirements of other countries and jurisdictions regarding quality, safety and efficacy and governing, among
other things, clinical trials, marketing authorization, commercial sales and distribution of our products. Whether or not we
obtain FDA approval for a product, we would need to obtain the necessary approvals by the comparable foreign regulatory
authorities before we can commence clinical trials or marketing of the product in foreign countries and jurisdictions.
Although many of the issues discussed above with respect to the United States apply similarly in the context of the
European Union, the approval process varies between countries and jurisdictions and can involve additional product testing
and additional administrative review periods. The time required to obtain approval in other countries and jurisdictions
might differ from and be longer than that required to obtain FDA approval. Regulatory approval in one country or
jurisdiction does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one
country or jurisdiction may negatively impact the regulatory process in others.

The Foreign Corrupt Practices Act

The Foreign Corrupt Practices Act, or FCPA, prohibits any U.S. individual or business from paying, offering, or
authorizing payment or offering of anything of value, directly or indirectly, to any foreign official, political party, or
candidate for the purpose of influencing any act or decision of the foreign entity in order to assist the individual or business
in obtaining or retaining business. The FCPA also obligates companies whose securities are listed in the United States to
comply with accounting provisions requiring the company to maintain books and records that accurately and fairly reflect
all transactions of the corporation, including international subsidiaries, and to devise and maintain an adequate system of
internal accounting controls for international operations. Activities that violate the FCPA, even if they occur wholly outside
the United States, can result in criminal and civil fines, imprisonment, disgorgement, oversight, and debarment from
government contracts.

European Union—EMA process

In the European Union, products follow a similar demanding process as that we described above for the United States and
the ICH Common Technical Document is the basis for applications.

Centralized Procedure

Under the centralized procedure, after the EMA issues an opinion, the European Commission issues a single marketing
authorization valid across the European Union, as well as Iceland, Liechtenstein and Norway. The centralized procedure is
compulsory for human products that are: derived from biotechnology processes, such as genetic engineering; contain a new
active substance indicated for the treatment of certain diseases, such as HIV/AIDS, cancer, diabetes, neurodegenerative
disorders or autoimmune diseases and other immune dysfunctions; and officially designated orphan drugs. For products
that do not fall within these categories, an applicant has the option of submitting an application for a centralized marketing
authorization to the EMA as long as the product concerned is a significant therapeutic, scientific or technical innovation, or
if its authorization would be in the interest of public health.

National Authorization Procedures

There are also two other possible routes to authorize medicinal products in several countries, which are available for
products that fall outside the scope of the centralized procedure:

•

Decentralized procedure. Using the decentralized procedure, an applicant may apply for simultaneous
authorization in more than one European Union country of a medicinal product that has not yet been authorized
in any European Union country and that does not fall within the mandatory scope of the centralized procedure.

• Mutual recognition procedure. In the mutual recognition procedure, a medicine is first authorized in one

European Union Member State, in accordance with the national procedures of that country. Thereafter, further

Business Update

marketing authorizations can be sought from other European Union countries in a procedure whereby the
countries concerned agree to recognize the validity of the original, national marketing authorization.

Good Manufacturing Practices

Like the FDA, the EMA, the competent authorities of the European Union Member States and other regulatory agencies
regulate and inspect equipment, facilities and processes used in the manufacturing of products prior to approving a product.
If, after receiving clearance from regulatory agencies, a company makes a material change in manufacturing equipment,
location, or process, additional regulatory review and approval may be required. Once we or our partners commercialize
products, we will be required to comply with cGMP, and product-specific regulations enforced by, the European
Commission, the EMA and the competent authorities of European Union Member States following product approval. Also
like the FDA, the EMA, the competent authorities of the European Union Member States and other regulatory agencies also
conduct regular, periodic visits to re-inspect equipment, facilities, and processes following the initial approval of a product.
If, as a result of these inspections, the regulatory agencies determine that our or our partners’ equipment, facilities, or
processes do not comply with applicable regulations and conditions of product approval, they may seek civil, criminal or
administrative sanctions or remedies against us, including the suspension of our manufacturing operations or the
withdrawal of our product from the market.

Data and Market Exclusivity

Similar to the United States, there is a process to authorize generic versions of innovative products in the European Union.
Generic competitors can submit abridged applications to authorize generic versions of products authorized by EMA
through a centralized procedure referencing the innovator’s data and demonstrating bioequivalence to the reference
product, among other things. New products in the European Union can receive eight years of data exclusivity coupled with
two years of market exclusivity, and a potential one-year extension, if the marketing authorizations holder obtains an
authorization for one or more new therapeutic indications that demonstrates “significant clinical benefit” in comparison
with existing therapies. This system is usually referred to as “8+2”. Abridged applications cannot rely on an innovator’s
data until after expiration of the eight year date exclusivity term, meaning that a competitor can file an application for a
generic product but the product cannot be marketed until the end of the market exclusivity term.

We are a clinical-stage biopharmaceutical company focused on the development and commercialization of novel
therapeutics for serious conditions that compromise a woman’s reproductive health and pregnancy. We are focused on
providing therapeutic solutions for women between the ages of 15 and 49 who suffer from reproductive health conditions
that affect their quality of life, ability to conceive or that complicate pregnancy and the health of newborns. Our goal is to
build the leading women’s reproductive health and pregnancy company focused on conditions where current treatment
options are limited and significant unmet needs exist.

We are developing OBE2109 as a novel, oral gonadotropin releasing hormone, or GnRH, receptor antagonist, for the
treatment of pain associated with endometriosis and heavy menstrual bleeding associated with uterine fibroids in pre-
menopausal women. We are currently conducting a multiple-dose, placebo-controlled Phase 2b clinical trial of OBE2109 in
approximately 330 patients with endometriosis, or the EDELWEISS clinical trial. Patient recruitment was completed in
November 2017, and we expect to report the primary efficacy results from the first 12-week evaluation period of this trial
in mid-2018. For the uterine fibroids indication, in April 2017, we initiated a Phase 3 clinical development program with
two Phase 3 clinical trials, or the PRIMROSE 1 and 2 clinical trials. We expect to report primary endpoint results from the
first 24-week evaluation period of these Phase 3 clinical trials in the second half of 2019 and 52-week data in the first half
of 2020.

We are also developing nolasiban, an oral oxytocin receptor antagonist, to improve clinical pregnancy and live birth rates in
women undergoing in-vitro fertilization, or IVF. We completed randomization of 778 patients in our European Phase 3
clinical trial in women undergoing IVF, or the IMPLANT2 clinical trial, in 2017 and reported positive topline results for
the primary endpoint of ongoing pregnancy 10 weeks post embryo transfer in February 2018.

In addition, we are developing OBE022, an oral and selective prostaglandin F2α receptor antagonist, for preterm labor in
weeks 24 to 34 of pregnancy. Based on results of Phase 1 clinical trials completed in the first quarter of 2017, we initiated a
Phase 2a proof-of-concept clinical trial, known as PROLONG, in December 2017. This trial will assess OBE022 safety,
and then efficacy in delaying childbirth in women at 24 to 34 weeks gestation who are experiencing symptoms of preterm
labor and potentially preterm delivery. We expect initial PK and safety results from Part A of this trial in a small subset of
patients during the second quarter of 2018 and preliminary efficacy results in an expanded subset of patients from Part B of
this trial in late 2018.

We were founded in November 2012 and our operations to date have included organizing and staffing our company, raising
capital, in-licensing rights to OBE2109, nolasiban and OBE022 and conducting nonclinical studies and clinical trials. To
date, we have not generated any revenue from product sales as none of our product candidates have been approved for
commercialization. We have historically financed our operations exclusively through the sale of equity. To date, we have
raised an aggregate of $238.1 million of net proceeds, including $88.5 million of net proceeds from our initial public
offering in January 2017 and $56.3 million of net proceeds from our private placement with institutional investors in
October 2017, and also acquired license rights on product candidates in 2013 and 2015 from the sale of preferred shares.

We have never been profitable and have incurred significant net losses in each period since our inception. Our net losses
were $66.9 million, $30.2 million, and $19.9 million for years ended December 31, 2017, 2016 and 2015, respectively. As
of December 31, 2017, we had accumulated losses of $137.3 million, out of which $30.6 million were offset with share
premium. This reclassification transaction had no impact on total equity. We expect to continue to incur significant
expenses and operating losses for the foreseeable future. We used $55.7 million and $28.6 million of cash in operations in
2017 and 2016, respectively, and we anticipate that our expenses will continue to increase significantly in connection with
our ongoing activities as we:

•

continue to invest in the clinical development of our product candidates and specifically in connection with our
ongoing EDELWEISS, PRIMROSE 1 and 2, IMPLANT2 and PROLONG clinical trials, and any additional
clinical trials, nonclinical studies and pre-commercial activities that we may conduct for product candidates;

hire additional research and development, and general and administrative personnel;

maintain, expand and protect our intellectual property portfolio;

identify and in-license or acquire additional product candidates; and
continue to incur additional costs associated with operating as a public company.

ObsEva S.A. - Annual Report 2017

We will need substantial additional funding to support our operating activities as we advance our product candidates
through clinical development, seek regulatory approval and prepare for and invest in future commercialization of these
candidates, if approved. Adequate funding may not be available to us on acceptable terms, or at all.

We have no manufacturing facilities, and all of our manufacturing activities are contracted out to third parties. We currently
utilize third-party contract research organizations, or CROs, to carry out our clinical development and trials. Additionally,
we do not yet have a commercialization organization.

Strategic Licensing Agreements

OBE2109

In November 2015, we entered into the Kissei license and supply agreement with Kissei Pharmaceutical Co., Ltd., or
Kissei. Pursuant to the Kissei license and supply agreement we received an exclusive license to develop, manufacture and
commercialize products, or the Product, containing the compounds which is a specified GnRH antagonist and covered by
certain licensed patent rights, or the Compound, throughout the world except for specified Asian countries. We arranged to
exclusively acquire from Kissei the material necessary to produce OBE2109.

In consideration for the license, we made an initial $10.0 million upfront payment. In addition, we agreed to make
aggregate milestone payments of up to $63.0 million upon the achievement of specified developmental milestones, such as
the initiation of clinical trials and receipt of regulatory approvals. In connection with the initiation of the Phase 3 clinical
program for OBE2109 in uterine fibroids in the second quarter of 2017, a $5.0 million milestone was paid. With respect to
any products we commercialize under the Kissei license and supply agreement, we agreed to make further payments of up
to an additional $125.0 million to Kissei upon the achievement of specified commercial milestones.

Pursuant to the Kissei license and supply agreement, we have agreed to exclusively purchase the active pharmaceutical
ingredient for OBE2109 from Kissei. During the development stage, we are obligated to pay Kissei a specified supply
price. Following the first commercial sale of licensed product, we are obligated to pay Kissei a royalty in the low twenty
percent range as a percentage of net sales. This payment includes Kissei’s supply of the active pharmaceutical ingredient
until the latest of (i) the date that the valid claim of a patent for the Product has expired, (ii) the expiration of our regulatory
exclusivity period, or (iii) 15 years from the first commercial sale of such product on a country-by-country and product-by-
product basis. During the term, we are restricted from developing, marketing and selling GnRH agonists and GnRH
antagonists other than the Compound to the extent allowed by applicable laws.

Nolasiban

In August 2013, we entered into the 2013 license agreement with Ares Trading S.A., an affiliate of Merck Serono, or
Merck Serono, pursuant to which we received a worldwide exclusive license to develop, manufacture and commercialize
compounds covered by the licensed patent rights, including nolasiban. In consideration for the license, we issued 914,069
Series A preferred shares to Merck Serono at the time of our Series A financing, which had a fair-value of $4.9 million
based on an exchange rate of $1.00 for CHF 0.9244 as of the date of the transaction. With respect to any products we
commercialize under the 2013 license agreement, we agreed to pay Merck Serono royalties based on a high-single-digit
percentage of annual net sales of each product, subject to specified reductions, until the later of (i) the date that all of the
patent rights for that product have expired, as determined on a country-by-country and product-by-product basis, or (ii) ten
years from the first commercial sale of such product on a country-by-country and product-by-product basis.

OBE022

In June 2015, we entered into the 2015 license agreement with Merck Serono, which we amended in July 2016, pursuant to
which we received a worldwide exclusive license to develop, manufacture and commercialize compounds covered by the
licensed patent rights, including OBE022. In consideration for the license, we issued 325,000 Series A preferred shares to
Merck Serono in September 2016 upon the initiation of a Phase 1 clinical trial for a licensed product. With respect to any
products we commercialize under the 2015 license agreement, we agreed to pay Merck Serono royalties based on a mid-
single-digit percentage of annual net sales of each product, subject to specified reductions, until the later of (i) the date that
all of the patent rights for that product have expired, as determined on a country-by-country and product-by-product basis
or (ii) ten years from the first commercial sale of such product on a country-by-country and product-by-product basis.

Operating Expenses
Research and Development Expenses

Research and development expenses consist primarily of costs incurred in connection with our research and development
activities and consist mainly of direct research and development costs, which include: costs associated with the use of
CROs and consultants hired to assist on our research and development activities; personnel expenses, which include
salaries, benefits and share-based compensation expenses for our employees; expenses related to regulatory affairs and
intellectual property; manufacturing costs in connection with conducting nonclinical studies and clinical trials; and
depreciation expense for assets used in research and development activities. Research and development costs are generally
expensed as incurred. However, costs for certain activities, such as manufacturing and nonclinical studies and clinical trials,
are generally recognized based on an evaluation of the progress to completion of specific tasks using information and data
provided to us by our vendors and collaborators.

Our employee, consultant and infrastructure resources are typically utilized across our multiple research and development
programs. We track outsourced research and development costs by product candidate or nonclinical program, but we do not
allocate personnel costs, other internal costs or external consultant costs to specific product candidates.

From inception through December 31, 2017, we have incurred $109.7 million in research and development expenses to
advance the development of our product candidates. The following table provides a breakdown of our outsourced research
and development expenses that are directly attributable to the specified product candidates for the years ended
December 31, 2017, 2016 and 2015, respectively.

We expect our research and development expense will increase for the foreseeable future as we seek to advance the
development of our product candidates through clinical trials and potentially toward regulatory submissions. At this time,
we cannot reasonably estimate or know the nature, timing and estimated costs of the efforts that will be necessary to
complete the development of our product candidates. We are also unable to predict when, if ever, material net cash inflows
will commence from sales of our product candidates. This is due to the numerous risks and uncertainties associated with
developing such product candidates, including:

•

the number of clinical sites included in the trials;

the length of time required to enroll suitable patients;

the number of patients that ultimately participate in the trials;

the number of doses patients receive;

the duration of patient follow-up;

the results of our clinical trials; and

regulatory requirements in support of potential approvals.

ObsEva S.A. - Annual Report 2017

Financial Review

In addition, the probability of success for any of our product candidates will depend on numerous factors, including
competition, manufacturing capability and commercial viability. A change in the outcome of any of these variables with
respect to the development of any of our product candidates would significantly change the costs, timing and viability
associated with the development of that product candidate.

General and Administrative Expenses

General and administrative expenses consist primarily of personnel expenses, including salaries, benefits and share-based
compensation expense, related to executive, finance, accounting, business development, legal and human resource
functions. General and administrative expense also includes facility costs not otherwise included in research and
development expenses, legal fees related to corporate matters, fees for accounting and consulting services, and costs of
director and officer insurance.

We anticipate that our general and administrative expense will increase in the future to support continued research and
development activities. We also anticipate that we will incur increased accounting, audit, legal, regulatory and compliance
costs, as well as investor and public relations expenses, associated with operating as a public company.

Finance Result, Net

Finance result, net, consists mainly of interest income and expense derived from our cash and cash equivalents and foreign
exchange gains and losses.

Taxation

We are subject to corporate taxation in Switzerland, Ireland and the United States.

In 2015, the Canton of Geneva granted us a ten year tax holiday for all income and capital taxes on a communal and
cantonal level commencing in fiscal year 2013 and valid through to 2022, subject to our Swiss domiciliation and
compliance with certain reporting provisions. We remain subject to Swiss federal income tax on our profits after tax but
have only incurred net losses since our inception. We are entitled under Swiss laws to carry forward any losses incurred for
a period of seven years and can offset such losses carried forward against future taxes. As of December 31, 2017, we had
tax loss carryforwards totaling $118.0 million. We do not believe it is probable that we will generate sufficient profits to
avail ourselves of these tax loss carryforwards.

Our Irish subsidiary had no activity in 2016 and 2017 and our U.S. subsidiary, as a service organization to the group under
cost plus arrangement, was the only entity to generate income tax expenses for the year ended December 31, 2017.

B. Liquidity and Capital Resources

Since our inception, we have not generated any revenue and have incurred net losses and negative cash flows from our
operations. We have funded our operations primarily through the sale of equity. From inception through December 31,
2017, we have raised an aggregate of $238.1 million of net proceeds from the sale of equity securities. In January 2017, we
completed our initial public offering of 6,450,000 common shares at a public offering price of $15.00 per share. We
received $88.5 million in net proceeds after deducting $8.3 million of underwriting discounts and commissions and other
offering expenses. Additionally, in October 2017, we raised $56.3 million of net proceeds after deducting $3.7 million of
placement expenses through the issuance of 7,500,000 shares at a price of $8.00 per share in a private placement with
institutional investors.

As of December 31, 2017, we had $110.8 million in cash and cash equivalents.

Our primary uses of cash are to fund operating expenses, primarily research and development expenditures. Cash used to
fund operating expenses is impacted by the timing of when we pay these expenses, as reflected in the change in our
outstanding accounts payable and accrued expenses. We currently have no ongoing material financing commitments, such
as lines of credit or guarantees.

We expect our expenses to increase in connection with our ongoing activities, particularly as we continue the research and
development of, continue or initiate clinical trials of, and seek marketing approval for, our product candidates. In addition,
if we obtain marketing approval for any of our product candidates, we expect to incur significant commercialization
expenses related to program sales, marketing, manufacturing and distribution to the extent that such sales, marketing and
distribution are not the responsibility of potential collaborators. Furthermore, we expect to continue to incur additional
costs associated with operating as a public company. Accordingly, we will need to obtain substantial additional funding in
connection with our continuing operations. If we are unable to raise capital when needed or on attractive terms, we could be
forced to delay, reduce or eliminate our research and development programs or future commercialization efforts.

We expect our existing cash and cash equivalents will enable us to fund our operating expenses and capital expenditure
requirements into the second half of 2019. We have based this estimate on assumptions that may prove to be wrong, and we
could exhaust our available capital resources sooner than we currently expect. Our future capital requirements will depend
on many factors, including:

•

the scope, progress, results and costs of our ongoing and planned nonclinical studies and clinical trials for
OBE2109, nolasiban and OBE022;

the cost and timing of ongoing and planned manufacturing activities including active pharmaceutical ingredient
and drug product pharmaceutical development and clinical trial supplies production for OBE2109, nolasiban
and OBE022;

the timing and amount of milestone and royalty payments we are required to make under our license
agreements;

the extent to which we in-license or acquire other product candidates and technologies;

the number and development requirements of other product candidates that we may pursue;

the costs, timing and outcome of regulatory review of our product candidates;

the costs and timing of future commercialization activities, including drug manufacturing, marketing, sales and
distribution, for any of our product candidates for which we receive marketing approval;

the revenue, if any, received from commercial sales of our product candidates for which we receive marketing
approval;

our ability to establish strategic collaborations; and

the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our
intellectual property rights and defending any intellectual property-related claims.

Identifying potential product candidates and conducting nonclinical studies and clinical trials is a time-consuming,
expensive and uncertain process that takes many years to complete, and we may never generate the necessary data or

ObsEva S.A. - Annual Report 2017

Financial Review

results required to obtain marketing approval and achieve product sales. In addition, our product candidates, if approved,
may not achieve commercial success. Our revenue, if any, will be derived from sales of products that we do not expect to
be commercially available for many years, if at all.

Until such time that we can generate substantial product revenue, if ever, we may finance our cash needs through a
combination of equity offerings, debt financings, collaborations, strategic alliances and licensing arrangements.

To the extent that we raise additional capital through the sale of equity or convertible debt securities, shareholder
ownership interest may be diluted, and the terms of any additional securities may include liquidation or other preferences
that adversely affect the rights of shareholders. 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 funds through additional collaborations, strategic alliances or licensing arrangements with third parties, we may
have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates, or
to grant licenses on terms that may not be favorable to us.

If we are unable to raise additional funds through equity or debt financings 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 product candidates that we would otherwise prefer to develop and market ourselves.

Operating Activities

Net cash used in operating activities consists of net loss before tax adjusted for changes in net working capital, or current
assets less current liabilities, and for non-cash items such as depreciation and amortization, as well as the value of share-
based services.

During the year ended December 31, 2017, $55.7 million of cash was used for operating activities, primarily as the result of
our net loss before tax of $66.9 million, as adjusted for non-cash items and changes in net working capital. Non-cash items
amounted to $8.3 million and mainly consisted of share-based payments. Changes in net working capital included primarily
a $1.7 million increase in accrued expenses, primarily due to the costs of our clinical trial supplies for our PRIMROSE 1
and 2 and EDELWEISS clinical trials, as well as a $0.7 million decrease in prepaid expenses, mainly attributable to upfront
payments made in relation to our PRIMROSE 1 and 2 clinical trials during 2016.

During the year ended December 31, 2016, $28.6 million of cash was used for operating activities, primarily as the result of
our net loss before tax of $30.2 million, as adjusted for non-cash items and changes in net working capital. Non-cash items
amounted to $2.0 million and mainly consisted of share-based payments. Changes in net working capital included primarily
a $2.0 million increase in prepaid expenses, primarily due to upfront payments made in relation to our PRIMROSE 1 and 2
clinical trials in uterine fibroids, as well as a $1.8 million increase in other payables and current liabilities mainly
attributable to our ongoing EDELWEISS clinical trial of OBE2109 in endometriosis and Phase 1 clinical trials of OBE022
during 2016.

During the year ended December 31, 2015, $13.9 million of cash was used for operating activities, primarily as the result of
our net loss before tax of $19.9 million, as adjusted for non-cash items and changes in net working capital. Non-cash items
amounted to $3.4 million and primarily consisted of share-based payments and the issuance of anti-dilutive common shares

ObsEva S.A. - Annual Report 2017

Financial Review

during our Series B financing in November 2015. Changes in net working capital included a $2.1 million increase in
accrued expenses, primarily due to the stamp duty due on the proceeds from the Series B financing, as well as to accrued
staff costs, including annual bonuses, and our ongoing clinical trials as of December 31, 2015.

Investing Activities

Net cash used in investing activities consists primarily of investments in leasehold improvements and furniture and fixtures,
as well as investments in intangible assets through the execution of in-licensing agreements or the payment of
development-based milestones to our licensors.

During 2017, net cash used in investing activities consisted primarily of a $5.0 million milestone payment to Kissei made
upon initiation of the Phase 3 clinical program for OBE2109 in uterine fibroids, as well as payments made for leasehold
improvements and furniture for the opening of our office in the United States. Net cash used in investing activities in 2016,
consisted primarily of purchase of furniture and fixtures for our office in Switzerland. Net cash used in investing activities
in 2015 mainly consisted of the $10.0 million upfront payment made to Kissei under the Kissei license and supply
agreement.

Financing Activities
Net cash from financing activities consists primarily of proceeds from the sale of equity securities.

Cash flows from financing activities in 2017 consisted mainly of the net proceeds from our initial public offering in
January 2017 and from our private placement with institutional investors in October 2017. Cash flows used in financing
activities in 2016 mainly consisted of payments for costs incurred in connection with our initial public offering and related
issuance of new shares. Cash flows from financing activities in 2015 mainly consisted of the proceeds from the Series B
financing and payments received for the second tranche of the Series A financing.

Under our license agreements with Kissei and Merck Serono, we may be required to pay royalties in the future. In addition,
pursuant to the Kissei license and supply agreement, we have agreed to make aggregate milestone payments of up to
$63.0 million upon the achievement of specified developmental milestones, such as the initiation of clinical trials and
receipt of regulatory approvals, of which we had paid $5.0 million as of December 31, 2017. With respect to any product

Financial Review

we commercialize under the Kissei license and supply agreement, we have agreed to make additional aggregate milestone
payments of up to $125.0 million to Kissei upon the achievement of specified commercial milestones.

We have not included any contingent payment obligation, such as milestone payments and royalties, in the table above as
the amount, timing and likelihood of such payments are not known.

We enter into contracts in the normal course of business with CROs for clinical trials, nonclinical studies, manufacturing
and other services and products for operating purposes. These contracts generally provide for termination upon notice, and
therefore we believe that our non-cancelable obligations under these agreements are not material.

Family Relationships
There are no family relationships among any of our executive officers or directors.

B. Compensation
For a discussion of compensation, see the Compensation Report section of this Annual Report.

C. Board Practices.

Our board of directors is composed of eight members. Each director is elected for a one-year term. The current members of
our board of directors were appointed at our annual general meeting of shareholders held on June 13, 2017 to serve until
our 2018 annual general meeting of shareholders.

We are a foreign private issuer. As a result, in accordance with the Nasdaq listing requirements, we may rely on home
country governance requirements and certain exemptions thereunder rather than relying on the stock exchange corporate
governance requirements. However, our board of directors has undertaken a review of the independence of the directors
and determined that, under current Nasdaq listing requirements, Frank Verwiel, Annette Clancy, Barbara Duncan, James I.
Healy, Ed Mathers, Rafaèle Tordjman and Jacky Vonderscher, representing seven of our eight directors, are “independent
directors.” In making such determination, our board of directors considered whether any director has a material relationship
with us that could compromise their ability to exercise independent judgment in carrying out their responsibilities. For an
overview of our corporate governance principles, see “Item 10.B—Memorandum and Articles of Association.”

Board Committees

Our board of directors has established an audit committee and a compensation, nominating and corporate governance
committee.

ObsEva S.A. - Annual Report 2017

Corporate Governance

Audit Committee

The audit committee, which consists of Barbara Duncan, Ed Mathers and Frank Verwiel, assists our board of directors in
overseeing our accounting and financial reporting processes and the audits of our financial statements. In addition, the audit
committee is directly responsible for the compensation, retention and oversight of the work of our independent registered
public accounting firm and statutory auditors who are appointed by the shareholders pursuant to Swiss corporation law.
Ms. Duncan serves as chairman of the committee. The audit committee consists exclusively of members of our board of
directors who are financially literate, and Ms. Duncan is considered an “audit committee financial expert” as defined by the
U.S. Securities and Exchange Commission, or SEC. Our board of directors has determined that Ms. Duncan, Mr. Mathers
and Dr. Verwiel satisfy the “independence” requirements set forth in Rule 10A-3 under the Exchange Act.

The audit committee is governed by a charter that complies with Nasdaq listing rules. The audit committee is responsible
for, among other things:

•

recommending an auditor for submission to the shareholders;

the compensation, retention and oversight of any auditor or accounting firm engaged for the purpose of
preparing or issuing an audit report or performing other audit, review or attest services;

pre-approving the audit services and non-audit services to be provided by our independent auditor before the
auditor is engaged to render such services;

reviewing and discussing with the independent auditor its responsibilities under generally accepted auditing
standards, the planned scope and timing of the independent auditor’s annual audit plan(s) and significant
findings from the audit;

obtaining and reviewing a report from the independent auditor describing all relationships between the
independent auditor and us consistent with the applicable Public Company Accounting Oversight Board
requirements regarding the independent auditor’s communications with the audit committee concerning
independence;

confirming and evaluating the rotation of the audit partners on the audit engagement team as required by law;

reviewing with management and the independent auditor, in separate meetings whenever the audit committee
deems appropriate, any analyses or other written communications prepared by the management or the
independent auditor setting forth significant financial reporting issues and judgments made in connection with
the preparation of the financial statements, including analyses of the effects of alternative IFRS methods on the
financial statements, and our other critical accounting policies and practices;

reviewing, in conjunction with our chief executive officer and chief financial officer, our disclosure controls
and procedures;

establishing procedures for the receipt, retention and treatment of complaints received by us regarding
accounting, internal accounting controls or auditing matters, and the confidential, anonymous submission by
our employees of concerns regarding questionable accounting or auditing matters; and

approving or ratifying any related party transaction (as defined in our related party transaction policy) in
accordance with our related party transaction policy.

The audit committee meets as often as it determines is appropriate to carry out its responsibilities, but in any event will
meet at least four times per year.

Compensation, Nominating and Corporate Governance Committee

Our compensation, nominating and corporate governance committee consists of three members, Annette Clancy, Rafaèle
Tordjman and James I. Healy. Our board of directors has determined that each of Ms. Clancy and Drs. Tordjman and Healy
are independent under the Nasdaq listing standards, are “non-employee directors” as defined in Rule 16b-3 promulgated
under the Exchange Act and are “outside directors” as that term is defined in Section 162(m) of the Code. The chair of our
compensation, nominating and corporate governance committee is Ms. Clancy. The primary purpose of our compensation,
nominating and corporate governance committee is to discharge our board of directors’ responsibilities to oversee our
compensation policies, plans and programs and to review and determine the compensation to be paid to our executive

ObsEva S.A. - Annual Report 2017

Corporate Governance

officers, directors and other senior management, as appropriate. We are subject to the Swiss Ordinance against excessive
compensation in listed stock corporations, known as the “Minder” rules. As a result of the Minder rules, the members of the
compensation, nominating and corporate governance committee must be elected by our shareholders and the aggregate
compensation of our board of directors and executive officers must also be approved by our shareholders.

In addition, this committee is also responsible for director nominations as well as reviewing and making recommendations
to the board, if required, on our corporate governance framework and guidelines.

The compensation, nominating and corporate governance committee has the responsibility to, among other things:

•

review and approve, or recommend that our board of directors approve, the compensation of our executive
officers based on the aggregate compensation approved by our shareholders;

review and recommend to our board of directors the compensation of our directors based on the aggregate
compensation approved by our shareholders;

review and approve, or recommend that our board of directors approve, the terms of compensatory
arrangements with our executive officers;

administer our share and equity incentive plans;

select independent compensation consultants and assess whether there are any conflicts of interest with any of
the committees’ compensation advisers;

review and approve, or recommend that our board of directors approve, incentive compensation and equity
plans, and any other compensatory arrangements for our executive officers and other senior management, as
appropriate;

review and establish general policies relating to compensation and benefits of our employees and reviewing our
overall compensation philosophy;

identify, evaluate and select, or recommend that our board of directors approve, nominees for election to our
board of directors;

evaluate the performance of our board of directors and of individual directors;

consider and make recommendations to our board of directors regarding the composition of the committees of
the board of directors;

review developments in corporate governance practices;

evaluate the adequacy of our corporate governance practices and reporting;

review management succession plans;

approve any loans by the company to executive officers (to the extent permitted by applicable law and our
articles of association) and loans by the company to employees that are not executive officers, where the
amount of any such loan exceeds $10,000;

develop and make recommendations to our board of directors regarding corporate governance guidelines and
matters; and

oversee periodic evaluations of the board of directors’ performance.

Other Corporate Governance Matters

The Sarbanes-Oxley Act of 2002, as well as related rules subsequently implemented by the SEC, requires foreign private
issuers, including our company, to comply with various corporate governance practices. In addition, Nasdaq rules provide
that foreign private issuers may follow home country practice in lieu of the Nasdaq corporate governance standards, subject
to certain exceptions and except to the extent that such exemptions would be contrary to U.S. federal securities laws.

Because we are a foreign private issuer, our members of our board of directors, executive board members and senior
management are not subject to short-swing profit and insider trading reporting obligations under Section 16 of the

ObsEva S.A. - Annual Report 2017

Corporate Governance

Exchange Act. They will, however, be subject to the obligations to report changes in share ownership under Section 13 of
the Exchange Act and related SEC rules.

D. Employees.

As of December 31, 2017, we had 39 employees. None of our employees are represented by any collective bargaining
agreements. We believe that we maintain good relations with our employees. At each date shown, we had the following

4 - Share Ownership.

The following table sets forth information with respect to the beneficial ownership of our common shares as of
December 31, 2017 for:

•

each beneficial owner of 5% or more of our outstanding common shares;

each of our directors and executive officers; and

all of our directors and executive officers as a group.

Beneficial ownership is determined in accordance with the rules of the SEC. These rules generally attribute beneficial
ownership of securities to persons who possess sole or shared voting power or investment power with respect to those
securities and include common shares issuable upon the exercise of options that are immediately exercisable or exercisable
within 60 days of December 31, 2017. Percentage ownership calculations are based on 37,131,262 common shares
outstanding as of December 31, 2017.

Except as otherwise indicated, all of the shares reflected in the table are common shares and all persons listed below have
sole voting and investment power with respect to the shares beneficially owned by them, subject to applicable community
property laws. The information is not necessarily indicative of beneficial ownership for any other purpose.

In computing the number of common shares beneficially owned by a person and the percentage ownership of that person,
we deemed outstanding common shares subject to options held by that person that are immediately exercisable or
exercisable within 60 days of December 31, 2017. We did not deem these shares outstanding, however, for the purpose of
computing the percentage ownership of any other person. Beneficial ownership representing less than 1% is denoted with
an asterisk (*).

We have experienced significant changes in the percentage ownership held by major shareholders as a result of our initial
public offering. Prior to our initial public offering in January 2017, our principal shareholders were Fund Sofinnova Capital
VII (16.6%), Sofinnova Venture Partners VIII, L.P. (13.0%), Novo A/S (11.7%), Ares Trading S.A. (7.9%), New
Enterprise Associates 15, L.P. (11.9%), HBM Healthcare Investments (Cayman) Ltd (8.0%) and Orbimed Private
Investments V, LP (8.0%).

In January 2017, we completed our initial public offering and listed our common shares on the Nasdaq Global Select
Market. In the initial public offering, we issued and sold 6,450,000 common shares. Upon the completion of our initial
public offering, 29,631,262 common shares were outstanding. While none of our existing shareholders sold common shares
in the initial public offering, the percentage ownership held by certain shareholders decreased as a result of the issuance of
the common shares sold by us in the initial public offering.

In October 2017, we completed a private placement of 5,140,625 common shares and warrants to purchase an aggregate of
2,359,375 common shares, which were exercised on October 13, 2017. Upon completion of the private placement,
37,131,262 common shares were outstanding.

As of December 31, 2017, we estimate that approximately 48% of our outstanding common shares were held in the United
States by eight holders of record. The actual number of holders is greater than these numbers of record holders, and
includes beneficial owners whose common shares are held in street name by brokers and other nominees. This number of
holders of record also does not include holders whose shares may be held in trust by other entities.

5 - Controls and Procedures.
Disclosure Controls and Procedures

Our Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal financial officer), after
evaluating the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act)
as of December 31, 2017, have concluded that, as of such date, our disclosure controls and procedures were effective and
ensured that information required to be disclosed by us in reports that we file or submit under the Exchange Act is
accumulated and communicated to our management, including our Chief Executive Officer (principal executive officer)
and Chief Financial Officer (principal financial officer), to allow timely decisions regarding required disclosure and is
recorded, processed, summarized and reported within the time periods specified by the SEC’s rules and forms.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal controls over financial reporting (as
defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) and for the assessment of the effectiveness of our
internal control over financial reporting. Under the supervision and with the participation of our Chief Executive Officer
(principal executive officer) and Chief Financial Officer (principal financial officer), management assessed our internal
control over financial reporting based upon the framework in Internal Control — Integrated Framework (2013) issued by
the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, our
management has concluded that our internal control over financial reporting was effective as of December 31, 2017.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements, and
can only provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial
statements. 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.

Attestation Report of the Registered Public Accounting Firm

This Annual Report does not include an attestation report of our registered public accounting firm due to a transition period
established by rules of the SEC for newly public companies.

Changes in Internal Control Over Financial Reporting

There has been no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange
Act) that occurred during the period covered by this Annual Report that has materially affected, or is reasonably likely to
materially affect, internal control over financial reporting.

Conduct of a Risk Assessment

The Company conducts risk management processes to identify and mitigate risks at an early stage. The responsibility for
risk assessment and management is allocated to the Chief Executive Officer, to members of the Executive Committee and
to other specialized corporate functions such as Group Finance. Financial risk management is described in more details in
note 3 to the Consolidated IFRS Financial Statements for the year ended December 31, 2017.

ObsEva S.A. - Annual Report 2017

Consolidated IFRS Financial Statements for the year ended December 31, 2017

Notes to the Consolidated Financial Statements

1. General information

ObsEva SA (the “Company”) was founded on November 14, 2012, and its address is 12 Chemin des Aulx, 1228 Plan-les-
Ouates, Geneva, Switzerland. The terms “ObsEva” or “the Group” refer to ObsEva SA together with its subsidiaries
included in the scope of consolidation (note 2.2).

The Group is focused on the development and commercialization of novel therapeutics for serious conditions that
compromise women’s reproductive health and pregnancy. The Group has a portfolio of three mid- to late-stage
development in-licensed compounds (OBE2109, nolasiban and OBE022) being developed in four indications. The Group
has no currently marketed products.

These consolidated financial statements are presented in dollars of the United States (USD), rounded to the nearest
thousand, except share and per share data, and have been prepared on the basis of the accounting principles described in
note 2.

These consolidated financial statements were authorized for issue by the Company’s Board of Directors (the “Board of
Directors”) on March 9, 2018.

2. Accounting principles applied in the preparation of the consolidated financial statements

2.1 Basis of preparation

These consolidated financial statements have been prepared in accordance with the International Financial Reporting
Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”). The consolidated financial
statements are based on a historical cost basis.

The preparation of financial statements in conformity with IFRS requires the use of certain critical accounting estimates. It
also requires management to exercise its judgement in the process of applying the Group’s accounting policies. The areas
involving a higher degree of judgement or complexity, or areas where assumptions and estimates are significant to the
consolidated financial statements, are disclosed in note 2.5.

Due to rounding, numbers presented throughout these consolidated financial statements may not add up precisely to the
totals provided. All ratios and variances are calculated using the underlying amount rather than the presented rounded
amount.

2.2 Scope of consolidation

Subsidiaries are all entities over which the Group has control. The Group controls an entity when the Group is exposed to,
or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its
power to direct the activities of the entity. Subsidiaries are fully consolidated from the date on which control is transferred
to the Group. They are deconsolidated from the date that control ceases.

The Company currently consolidates the financial operations of its two fully-owned subsidiaries, ObsEva Ireland Ltd,
which is registered in Cork, Ireland and organized under the laws of Ireland, and ObsEva USA Inc., which is registered and
organized under the laws of Delaware, USA. ObsEva Ireland Ltd had no operations and no results of operations to report as
of December 31, 2017 and 2016. ObsEva USA Inc. had no operations and no results of operations to report as of December
31, 2016.

2.3 Standards and interpretations published by the IASB

The IASB and the International Financing Reporting Standards Interpretations Committee have recently issued new
standards and interpretations to be applied to the Group’s consolidated financial statements.

No new standards and amendments applied by the Group in 2017 had an impact on its consolidated financial statements.

ObsEva S.A. - Annual Report 2017

Consolidated IFRS Financial Statements for the year ended December 31, 2017

In 2018, the Group will adopt the following new relevant standards:

IFRS 9 Financial Instruments, effective on January 1, 2018, with early adoption allowed

In July 2014, the IASB issued IFRS 9 Financial Instruments which replaces International Accounting Standard (“IAS”) 39
Financial Instruments: Recognition and Measurement. The new standard will change the classification and measurement
requirements of financial assets and financial liabilities and the general hedge accounting rules. The Group’s financial
assets and liabilities only consisting of cash and cash equivalents, other receivables, other payables and accruals, and with
all of those being recognized at amortized cost, the Group does not expect the adoption of the new standard will have a
material impact on its consolidated financial statements.

IFRS 15 Revenue from Contracts with Customers, effective on January 1, 2018, with early adoption allowed

In May 2014, the IASB issued IFRS 15 Revenue from Contracts with Customers which replaces IAS 11 Construction
Contracts and IAS 18 Revenue and related interpretations. The new standard will establish the principles that an entity shall
apply to report useful information to users of financial statements about the nature, amount, timing, and uncertainty of
revenue and cash flows arising from a contract with a customer. Due to the absence of revenue for the Group, the adoption
of the new standard is not expected to have an impact on the Group’s consolidated financial statements.

In 2019, the Group expects to adopt the following new relevant standards:

IFRS 16 Leases, effective for annual periods beginning on or after January 1, 2019

In January 2016, the IASB issued IFRS 16 Leases, which replaces IAS 17 Leases and related interpretations. The new
standard will require lessees to recognize a lease liability reflecting future lease payments and a right-of-use asset for
virtually all lease contracts. The Group is in the process of evaluating the impact IFRS 16 may have on its consolidated
financial statements.

Other new standards and amendments published but not yet effective will have no material impact on the consolidated
financial statements of the Group.

2.4 Significant accounting policies

Current assets

Other receivables and other current receivables or prepayments are carried at their nominal value.

Individual receivables that are known to be uncollectible are written off by reducing the carrying amount directly. The
Group considers that there is evidence of impairment if any of the following indicators are present:

•

significant financial difficulties of the debtor;

probability that the debtor will enter bankruptcy or financial reorganization; and

default or delinquency in payments (more than 30 days overdue).

Receivables for which an impairment provision was recognized are written off against the provision when there is no
expectation of recovering additional cash.

Furniture, fixtures and equipment

Furniture, fixtures and equipment are carried at cost less depreciation and impairment. Historical cost includes expenditure
that is directly attributable to the acquisition of the items. Depreciation is calculated using the straight-line method, on the
basis of the following useful lives:

• furniture
• hardware
• leasehold improvement

5 years
3 years
duration of lease

ObsEva S.A. - Annual Report 2017

Consolidated IFRS Financial Statements for the year ended December 31, 2017

Furniture, fixtures and equipment are reviewed for impairment whenever events or changes in circumstances indicate that
their carrying amount may not be recoverable, on an individual basis. An impairment loss is recognized for the amount by
which the asset’s carrying amount exceeds its recoverable amount.

The assets’ residual values and useful lives are reviewed, and adjusted if appropriate, at the end of each reporting period.

Intangible assets

Separately acquired patents, licenses and other intangible assets are recorded at historical cost and subsequently measured
at cost less accumulated amortization and any impairment losses.

The acquisition of certain intangible assets, mainly licenses, may involve additional payments contingent on the occurrence
of specific events or milestones. Unless the Group already has a present obligation to make the payment at a future date, the
initial measurement of the intangible asset does not include such contingent payments. Instead, such payments are
subsequently capitalized as intangible assets when the contingency or milestone occurs.

Estimated useful life is the lower of legal duration and economic useful life, which does not exceed 20 years. The estimated
useful life of the intangible assets is annually reviewed, and if necessary, the future amortization charge is accelerated.

For licenses, the amortization starts when the assets become available for use, generally once proper regulatory and
marketing approval are obtained.

Intangible assets are subject to impairment testing annually, and whenever events or changes in circumstances indicate that
the carrying amount may not be recoverable.

Post-employment benefits

Group companies operate various pension schemes.

All employees of ObsEva SA participate in a retirement defined benefit plan. A defined benefit plan is a pension plan that
defines an amount of pension benefit that an employee will receive on retirement, usually dependent on one or more factors
such as age, years of service and compensation. The liability recognized in the balance sheet in respect of defined benefit
pension plans is the present value of the defined benefit obligation at the end of the reporting period less the fair value of
plan assets. The defined benefit obligation is calculated annually by an independent actuary, using the projected unit credit
method. The present value of the defined benefit obligation is determined by discounting the estimated future cash outflows
using interest rates of high-quality corporate bonds that are denominated in the currency in which the benefits will be paid,
and that have terms to maturity approximating to the terms of the related pension obligation.

Actuarial gains and losses arising from experience adjustments and changes in actuarial assumptions are charged or
credited to equity in other comprehensive income in the period in which they arise. Past-service costs are recognized
immediately in the consolidated statement of comprehensive loss.

During 2017, ObsEva USA, Inc established a 401K, defined contribution plan, for the employees of the company. A
defined contribution plan is a pension plan under which the amounts paid by the employer are fixed in advance. The plan
assets are held by a third party custodian. ObsEva USA, Inc. contributions to the defined contribution plan are charged to
the income statement as incurred. The Group has no further obligation once the contributions have been paid.

Equity

Incremental costs directly attributable to the issuance of common shares and options are recognized as a deduction from
equity, net of any tax effects.

ObsEva S.A. - Annual Report 2017

Consolidated IFRS Financial Statements for the year ended December 31, 2017

Research and development

Research expenses are charged to the consolidated statement of comprehensive loss as incurred. Development expenses are
capitalized as intangible assets when it is probable that future economic benefits will flow to the Group, and the following
criteria are fulfilled:

•

it is technically feasible to complete the intangible asset so that it will be available for use or sale;

management intends to complete the intangible asset and use or sell it;

there is an ability to use or sell the intangible asset;

adequate technical, financial and other resources to complete the development and to use or sell the intangible
asset are available; and

the expenditure attributable to the intangible asset during its development can be reliably measured.

In the opinion of management, due to uncertainties inherent in the development of the Group’s product candidates, the
criteria for development costs to be recognized as an asset as defined by IAS 38 Intangible Assets are not met.

Foreign currencies

Functional and presentation currency

Items included in the consolidated financial statements of the Group are measured using the currency of the primary
economic environment in which each Group’s entity operates (the “functional currencies”).

Until December 31, 2016, the functional currency of the Company was the Swiss franc (CHF). As from January 1, 2017,
due to a change of its primary economic environment, the functional currency of ObsEva SA became the US dollar (USD),
which is also the functional currency of ObsEva USA, Inc. and the presentation currency of the Group.

Transactions and balances

Foreign currency transactions are translated into the functional currency using the exchange rates at the dates of the
transactions or valuation where items are re-measured. Foreign exchange gains and losses resulting from the settlement of
such transactions and from the translation of monetary assets and liabilities denominated in foreign currencies at year end
exchange rates are recognized in profit or loss.

Foreign exchange gains and losses that relate to borrowings are presented in the consolidated statement of comprehensive
loss, within finance costs. All other foreign exchange gains and losses are presented in the consolidated statement of
comprehensive loss on a net basis within other income or other expenses.

Translation into the presentation currency until December 31, 2016

The results and financial position of operations that had a functional currency different from the presentation currency were
translated into the presentation currency as follows:

•

assets and liabilities were translated at the exchange rate prevailing on December 31 of each year;

income and expenses were translated at average exchange rates; and

all resulting exchange differences were recognized in other comprehensive income.

The following rates have been used for the translation from the functional currency to the presentation currency:

Share-based compensation

The Group operates two equity incentive plans.

A share-based, equity-settled, plan was formally set-up by the Group in 2013 (the “2013 EIP”). Participants eligible for
awards under the 2013 EIP are executives, directors, employees, agents and consultants. The fair value of the shares
granted under the 2013 EIP is determined at each grant date by using either an option pricing method that uses a Black-
Scholes model or a hybrid method, as appropriate, both based on a combination of the discounted cash flow method, under
the income approach, and the backsolve method.

A share-based, equity-settled, plan was formally set-up by the Group in 2017 (the “2017 EIP”). Participants eligible for
awards under this plan are executives, directors, employees, agents and consultants. The fair value of the stock-options
granted under the 2017 EIP is determined at each grant date by using a Black-Scholes model.

When the equity instruments granted do not vest until the counterparty completes a specified period of services, the Group
accounts for those services as they are rendered by the counterparty, during the vesting period, with a corresponding
increase in equity.

Deferred income taxes

Deferred income tax is provided in full, using the liability method, on temporary differences arising between the tax bases
of assets and liabilities and their carrying amounts in the consolidated financial statements. However, if the deferred
income tax arises from initial recognition of an asset or liability in a transaction other than a business combination that at
the time of the transaction affects neither accounting nor taxable profit and loss, it is not accounted for. Deferred income
tax is determined using tax rates and laws that have been enacted or substantively enacted by the balance sheet date and are
expected to apply when the related deferred income tax asset is realized or the deferred income tax liability is settled.

Deferred income tax assets are recognized to the extent that it is probable that future taxable profit will be available against
which the temporary differences can be utilized.

Leases

Leases of assets under which all the risks and rewards of ownership are effectively retained by the lessor are classified as
operating leases, and payments made are charged to the statement of comprehensive loss on a straight-line basis.

Segment information

The Group operates in one segment, which is the research, development of innovative women’s reproductive, health and
pregnancy therapeutics. The marketing and commercialization of such therapeutics depend, in large part, on the success of
the development phase. The Chief Executive Officer of the Company reviews the consolidated statement of operations of
the Group on an aggregated basis and manages the operations of the Group as a single operating segment.

The Group currently generates no revenue from the sales of therapeutics products.

The Group’s activities are not affected by any significant seasonal effect.

2.5 Critical accounting estimates and judgments

Estimates and judgments are continually evaluated and are based on historical experience and other factors, including
expectations of future events that are believed to be reasonable under the circumstances.

Critical accounting estimates and assumptions

The Group makes estimates and assumptions concerning the future. The resulting accounting estimates will not necessarily
equal to related actual outcome. The following areas involve a higher degree of judgement or complexity or are areas where
assumptions and estimates can have a significant impact on the consolidated financial statements:

•

Post-employment obligations: the actuarial valuation involves making assumptions about discount rates, future
salary increases, mortality rates and future pension increases. Due to the long-term nature of these plans, such
estimates are subject to significant uncertainty (note 10);

Share-based compensation: the determination of the fair value of the equity instruments granted involves the
use of certain assumptions subject to judgement (note 18);

Commencement of depreciation and amortization: the depreciation and amortization starts when the assets are
available for use in the manner intended by management, which requires judgement (notes 7 and 8);

Research and development costs: the Group recognizes expenditure incurred in carrying out its research and
development activities until it becomes probable that future economic benefits will flow to the Group, which
results in recognizing such costs as intangible assets, involving a certain degree of judgement (note 13);

Deferred taxes: the recognition of deferred tax assets requires assessment of whether it is probable that
sufficient future taxable profit will be available against which the deferred tax assets can be utilized (note 16);

Impairment of assets: as part of impairment tests, the recoverable amounts of tested assets have been
determined based on fair value calculations requiring the use of certain assumptions, subject to judgement (note
8);

Changes in functional currency: the determination of the functional currencies of Group’s companies based on
the primary economic environment of each entity requires a certain degree of judgement from management.

3. Financial risk management

3.1 Financial risk factors

The Group’s activities expose it to a variety of financial risks such as foreign exchange risk, credit risk, interest rate risk
and liquidity risk. The Group’s overall risk management program focuses on the unpredictability of financial markets and
seeks to minimize potential adverse effects on the Group’s financial performance. Financial risk management is carried out
by the Group`s finance department subject to and pursuing policies approved by the Board of Directors.

Foreign exchange risk

The Group operates internationally and is exposed to foreign exchange risk arising from various currency exposures,
primarily with respect to the Swiss franc (CHF), Euro (EUR) and British Pound (GBP). Foreign exchange risk arises from
future commercial transactions (e.g. costs for clinical services) and recognized assets and liabilities. Management has set up
a policy to manage the foreign exchange risk against their functional currency. To manage its foreign exchange risk arising
from future commercial transactions and recognized assets and liabilities, the Group’s finance department maintains
foreign currency cash balances to cover anticipated future requirements.

The sensitivity of profit or loss to changes in the exchange rates in the reported periods are as follows:

Credit risk

Cash and cash equivalents are deposited with top tier banks and institutions with a short term rating of “A-1” or “P-1” with
Standard & Poor’s and Moody’s, respectively.

The maximum credit risk exposure the Group faces in connection with its financial assets, being cash and cash equivalents
and other receivables, is the carrying amounts of these balances as shown in the consolidated balance sheet.

Interest rate risk

The Group’s exposure to interest rate fluctuations is limited because the Group has no interest-bearing indebtedness.

ObsEva S.A. - Annual Report 2017

Consolidated IFRS Financial Statements for the year ended December 31, 2017

Liquidity risk

The Group’s principal source of liquidity is the cash reserves which are obtained through the issuance of new shares. The
Group’s policy is to invest these funds in low risk investments including interest bearing deposits. The ability of the Group
to maintain adequate cash reserves to sustain its activities in the medium term is subject to risk as it is highly dependent on
the Group’s ability to raise further funds from the sale of new shares.

3.2 Capital management

The Group’s objectives when managing capital are to safeguard the Group’s ability to continue as a going concern in order
to ensure the financing of successful research and development activities so that future profits can be generated and to
maintain sufficient financial resources to mitigate against risks and unforeseen events.

The Group is also subject to capital maintenance requirement under Swiss law. To ensure that statutory capital
requirements are met, the Group monitors capital periodically.

3.3 Fair value estimation and financial instruments

The carrying value less impairment provision of receivables and payables approximate their fair values due to their short-
term nature.

All financial assets and liabilities, respectively, are held at their amortized cost.

The Group’s financial assets consist of cash and cash equivalents and other receivables which are classified as loans and
receivables at amortized costs according to IAS 39. The Group’s financial liabilities consist of other payables and accruals
which are classified as other liabilities at amortized cost according to IAS 39.

and to third parties and carried at amortized cost.

All payables have a contract maturity within 1 year.

6. Prepaid expenses and deferred costs

As at December 31, 2017, prepaid expenses and deferred costs only consist of prepaid expenses.

As at December 31, 2016, prepaid expenses and deferred costs include USD 2.1 million of prepayments and USD 0.3
million of costs which were incurred in connection with the Company’s Initial Public Offering (“IPO”) and related issuance
of new shares. These costs, which consisted principally of legal fees, were deferred and deducted from equity upon
issuance of the new shares.

As at December 31, 2017, the Group holds a number of licenses to operate several biopharmaceutical product candidates,
the value of which is recorded at USD 21.6 million (2016: USD 16.6 million).

Merck Serono licenses

On August 28, 2013, the Group in-licensed nolasiban for USD 4.9 million from Ares Trading S.A., an affiliate of Merck
Serono (“Merck Serono”).

In June 2015, the Group acquired the in-license for OBE022 from Merck Serono for an amount of USD 2.4 million.

Kissei license

On November 19, 2015, the Group entered into an exclusive in-license and supply agreement with Kissei Pharmaceutical
Co., Ltd. (“Kissei”) to acquire the product candidate OBE2109 for which Kissei successfully completed Phase 2 trial in
Japan. This in-license agreement grants the Group an exclusive license to use, develop and commercialize the product
candidate worldwide excluding certain Asian countries. This in-license was acquired for an upfront cash consideration of
USD 10 million, with additional contingent payments upon occurrence of certain milestones (note 19).

ObsEva S.A. - Annual Report 2017

Consolidated IFRS Financial Statements for the year ended December 31, 2017

On April 25, 2017, the Group announced the initiation of its Phase 3 clinical program for OBE2109 in uterine fibroids and
related activation of sites and start of recruitment. This event triggered the recognition and payment of a USD 5.0 million
milestone to Kissei during the second quarter of 2017, that was accounted for as an intangible asset.

The Group has concluded that the Merck Serono licenses and the Kissei license acquisitions do not qualify as business
combinations per IFRS 3, as the Group did not acquire processes that are capable of producing outputs given the in-
licensed compounds are very early-stage.

Amortization and impairment

The licenses are currently not amortized as no regulatory and marketing approvals were obtained.

In accordance with IAS 38, the licenses have been reviewed for impairment by assessing the fair value less costs of
disposal (“FVLCOD”). The valuation is considered to be Level 3 in the fair value hierarchy due to unobservable inputs
used in the valuation. No impairment was identified.

The key assumptions used in the valuation model (income approach) to determine the FVLCOD of the licenses are as
follows:

•

Expected research and development costs;

Probabilities of achieving development milestones based on industry standards;

Reported disease prevalence;

Expected market share;

Drug reimbursement, costs of goods and marketing expenses; and

Expected patent life.

The valuation model covers a 20-year period due to the length of the development cycle for assets of this nature. A discount
factor of 15%, based on the assumed cost of capital for the Group, has been used over the forecast period.

Based on sensitivity analysis performed, including changes in discount rates and peak sales assumptions, no reasonably
possible change in assumption would cause the carrying value of the licenses to exceed their recoverable amount.

9. Other long-term assets and liabilities

The Group’s other long-term assets mainly consist of security rental deposits for the Group’s offices.

The Group’s other long-term liabilities consist of long-term components of rent costs for ObsEva USA Inc.

10. Post-employment benefits

In accordance with the mandatory Swiss pension fund law, all employees of the Company participate in a retirement
defined benefit plan. Swiss based pension plans are governed by the Swiss Federal Law on Occupational Retirement,
Survivors’ and Disability Pension Plans (the “LPP”), which stipulates that pension plans are to be managed by independent,
legally autonomous units. Under the terms of the pension plan, participants are insured against the financial consequences
of old age, disability and death. The various insurance benefits are governed by regulations, with the LPP specifying the
minimum benefits that are to be provided. The employer and employees pay contributions to the pension plan. In the event
the pension plan’s statutory funding falls below a certain level, various measures can be taken to increase funding above
such level, such as increasing the current contribution, lowering the interest rate on the retirement account balances or
reducing the additional prospective benefits. The employer can also make additional restructuring contributions. Since the
risks of death and disability are fully reinsured by an insurance group, the savings plan must be qualified as a defined
benefit plan. As required by IAS 19 Employee Benefits, the projected unit credit method has been used in the calculation of
present value of the benefit obligations and the related current service cost.

ObsEva S.A. - Annual Report 2017

Consolidated IFRS Financial Statements for the year ended December 31, 2017

The investment risk is borne by the insurer and the reinsurer respectively, and the investment decision is taken by the board
of trustees of the collective insurance.

In 2016, the pension fund changed the pension conversion rates, what has been considered as an amendment of the pension
plan.

To develop the expected long-term rate of return on asset assumption, the Group considered the current level of expected
returns on risk free investments (high-quality corporate bonds), the historical level of the risk premium associated with the
other asset classes in which the portfolio is invested, and the expectation for future returns of each asset allocation.

Share capital and share premium

As at December 31, 2017, the total outstanding share capital of USD 2.9 million, fully paid, consisted of 36,342,945
common shares, excluding 778,134 non-vested shares and 10,183 treasury shares. As at December 31, 2016, the total
outstanding share capital of USD 1.7 million consisted of 2,215,434 common shares, 8,031,777 series A preferred shares,
11,079,549 series B preferred shares and 611,637 non-voting shares, excluding 1,237,665 non-vested non-voting shares and
5,200 treasury non-voting shares. Series A preferred shares and series B preferred shares had preferential rights as to the
liquidation proceeds within the terms of the article of association, and conferred the same voting rights as those attached to
common shares. Non-voting shares were part of the non-voting share capital and had the same financial rights than those
attached to common shares, with no right to vote or to participate in the ordinary and extraordinary meetings of the Group.
The Company’s non-voting shares and series A and series B preferred shares were converted into common shares upon the
closing of the IPO. All shares have a nominal value of 1/13 of a Swiss franc, translated into USD using historical rates at
the issuance date.

On February 23, 2016, the shareholders approved for statutory purposes a resolution to offset the accumulated losses with
the share premium balance for an amount of USD 30.6 million. This transaction had no impact on the overall equity
position.

In August 2016, the Group’s product candidate known as OBE022 entered into a Phase 1 clinical trial, triggering the
obligation of payment to Merck Serono of the 325,000 series A preferred shares due upon occurrence of that event. The
325,000 shares were issued through a capital increase of the Group on September 28, 2016, and an amount of USD
2.4 million was reclassified from the share-based payment reserve to the share premium.

On January 30, 2017, the Company completed an IPO and issued 6,450,000 common shares at a subscription price of USD
15.00 per share and a par value of 1/13 of a Swiss franc per share. The gross proceeds of USD 96.8 million have been
recorded in equity net of directly related share issuance costs of USD 8.2 million.

On October 13, 2017, the Company completed a private placement with institutional investors and issued 7,500,000
common shares at a subscription price of USD 8.00 per share and a par value of 1/13 of a Swiss franc per share. The gross
proceeds of USD 60.0 million have been recorded in equity net of directly related share issuance costs of USD 3.7 million.

Equity incentive plans

In 2017, the Company issued 454,548 common shares (2016: 264,524 non-voting shares) under its 2013 EIP (see note 18).
All shares and non-voting shares issued under the 2013 EIP have a nominal value of 1/13 of a Swiss franc, translated into
USD using historical rates at the issuance date.

Due to the difficulty in assessing when research and development projects would generate revenue, the Group expenses all
research and development costs on the consolidated statement of comprehensive loss. In 2017, research and development
expenses amounted to USD 54.9 million (2016: USD 23.7 million, 2015: USD 16.9 million).

The Group employed on average 32.3 full-time equivalents (“FTE”) in 2017, compared to 22.4 FTE in 2016 and 16.2 FTE
in 2015, and 37.7 FTE as at December 31, 2017 compared to 25.3 FTE as at December 31, 2016 and 19.9 FTE as at
December 31, 2015.

For the year ended December 31, 2016, the post-employment benefits line includes a gain of USD 512 thousand relating to
the plan amendment enacted in 2016.

15. Finance income and expense
Finance income mainly relates to foreign exchange gains and interests on bank deposits.

Finance expense mainly relates to foreign exchange losses and interest expense.

16. Income taxes and deferred taxes

The Group is subject to income taxes in Switzerland, Ireland and the United States.

The Company is subject in Switzerland to a municipal and cantonal income tax rate of 22.6% and to a federal tax rate of
8.5% on its profits after tax. It is entitled to carry forward any loss incurred for a period of seven years and can offset such
losses carried forward against future taxes. In 2015, the Company was granted by the State Council of the Canton of
Geneva an exemption of income and capital tax at municipal and cantonal levels for the period from 2013 until 2022.
Because of this exemption, and the fact that the Company has incurred net losses since its inception, no income tax expense
at the municipal, cantonal or federal levels was recorded in the Company for the years ended December 31, 2017 and 2016.
Additionally, due to the uncertainty as to whether it will be able to use its net loss carryforwards for tax purposes in the

The Company’s Irish subsidiary has no activity, and, therefore, no income tax expense was recorded in such entity for the
years ended December 31, 2017 and 2016.

ObsEva S.A. - Annual Report 2017

Consolidated IFRS Financial Statements for the year ended December 31, 2017

The Company’s U.S. subsidiary, ObsEva USA Inc., is a service organization for the Group and is therefore subject to taxes
on the revenues generated from its services to the Group that are charged based upon the U.S. subsidiary’s cost plus
arrangement with the Group. Because the U.S. subsidiary started operating in January 2017, no income tax expense was
recorded in such entity for the year ended December 31, 2016. The profits of the U.S. subsidiary for the year ended
December 31, 2017 were subject to a total U.S. income tax rate of 39.3% based on both the U.S. federal and Massachusetts
state tax rates. The income tax for the year ended December 31, 2017 was USD 51 thousand. Additionally, due to the
uncertainty as to whether ObsEva USA Inc. will be able to use a deferred tax asset for tax purposes in the future, no
deferred taxes have been recognized on the balance sheet of the Group as of December 31, 2017 and December 31, 2016.

As of December 31, 2017, the Company has one category of shares, which are common shares. As of December 31, 2016
and 2015, the Company’s shares were comprised of ordinary shares, consisting of both common shares and non-voting
shares, and series A and series B preferred shares. The Company’s non-voting shares and series A and series B preferred
shares were converted into common shares upon the closing of the IPO on January 25, 2017.

For the years ended December 31, 2016 and 2015, as the series A and series B preferred shares participated with ordinary
shares in the profit or loss on a pro-rata basis, the net loss was allocated to each class pro-rata to their weighted average
number of shares outstanding during the period.

The basic loss per share is calculated by dividing the loss of the period attributable to the ordinary shares by the weighted
average number of ordinary shares (common and non-voting) outstanding during the period as follows:

Employee equity incentive plan 2013

The Company established the 2013 EIP for employees, executives, directors and consultants (the “Beneficiaries”) of the
Group.

Upon enrollment in the 2013 EIP, Beneficiaries were granted a certain number of shares which they were entitled to
acquire at a pre-determined price of 1/13 of a Swiss franc. The pre-determined price was generally paid by the
Beneficiaries at the grant date and recognized as a pre-payment until the vesting period elapses resulting in the shares
issuance being accounted for.

The shares generally fully vest over a four year vesting period, with 25% of the shares underlying the grant vesting after
one year, and 1/48th of the shares underlying the grant vesting each month over a further period of three years.

The Group has no present obligation to repurchase or settle the shares in cash.

ObsEva S.A. - Annual Report 2017

The fair value of the shares was calculated using a combination of the discounted cash flow method, under the income
approach, and the backsolve method. The income approach estimates value based on the expectation of future cash flows
that the Company will generate, such as cash earnings, costs savings, tax deduction and the proceeds from disposition.
These future cash flows were discounted to their present values using a discount rate derived based on an analysis of the
cost of capital of comparable publicly traded companies in similar lines of business, as of each valuation date, and was
adjusted to reflect the risks inherent in the Company’s cash flows. The backsolve method, a form of the market approach to
valuation, derives the implied enterprise equity value and the fair value of the non-voting share from a recent and
contemporaneous transaction involving the Company’s own securities, using the following assumptions: rights and
preferences of the different categories of shares, probability of various liquidity event scenarios, expected timing of a
liquidity event, volatility and expected value in a liquidity event.

The Group has stopped granting equity instruments under the 2013 EIP in 2016.

Employee equity incentive plan 2017

The Company established in 2017 the 2017 EIP for Beneficiaries of the Group, under which 1,866,740 stock-options were
granted during the year ended December 31, 2017. The stock-options vest under a 3-year or 4-year vesting schedule, have a
10-year expiration term and have a strike price equivalent to the share price at grant date.

Movements in the number of stock-options outstanding under the 2017 EIP were as follows:

The weighted average fair value of the stock-options granted during the year ended December 31, 2017, determined using a
Black-Scholes model was USD 6.98. The significant inputs to the model were:

Since the Company has a short track record as a public company, expected volatility has been determined based on the
historical trend of an appropriate sample of public companies operating in the biotech and pharmaceutical industry.

Anti-dilution provisions

The shareholders’ agreement signed in 2013 included specific anti-dilution clauses benefiting one of the Group’s founders,
Ernest Loumaye (the “Founder”). Subject to specified exceptions, per this clause, if, as a result of a share issuance, the
Founder’s shareholding in the Group’s certain classes of shares was diluted below 10%, then the Founder was entitled to
acquire at nominal value (1/13 of a Swiss franc) a number of common shares allowing him to maintain his shareholding at
10%.

In November 2015, the completion of a round of financing (note 11) triggered this clause which resulted in the issuance of
915,434 common shares to the Founder.

In accordance with IFRS 2, such transaction resulted in a share-based expense of USD 2.4 million for the year ended
December 31, 2015. The fair value of the common shares delivered to the Founder was calculated using a backsolve
method (USD 2.68).

The anti-dilution provisions are no longer effective and had no impact on the years ended December 31, 2017 and 2016.

Contingencies

As a result of the licenses granted to the Group, the following contingencies are to be noted:

Kissei license

Under the terms of the license and supply agreement, the Group would be obligated to make milestone payments upon the
achievement of specified regulatory milestones with respect to OBE2109. The total of all potential undiscounted future
payments that the Group could be required to make under this arrangement ranges between USD 0 and USD 188 million,
of which USD 5 million have already been paid.

ObsEva S.A. - Annual Report 2017

Consolidated IFRS Financial Statements for the year ended December 31, 2017

Pursuant to the Kissei license and supply agreement, the Group has agreed to exclusively purchase the active
pharmaceutical ingredient for OBE2109 from Kissei. During the development stage, the Group is obligated to pay Kissei a
specified supply price. Following the first commercial sale of licensed product, the Group is obligated to pay Kissei a
royalty payment in the low twenty percent range as a percentage of net sales, which includes payment for Kissei’s supply
of the active pharmaceutical ingredient until the latest of the date that the valid claim of a patent for the product has
expired, the expiration of our regulatory exclusivity period or 15 years from the first commercial sale of such product on a
country-by-country and product-by-product basis.

Merck Serono licenses

Under the terms of the two license agreements with Merck Serono for nolasiban and OBE022, the Group would be
obligated to pay Merck Serono a high-single digit and a mid-single digit royalty, respectively, of net sales generated by the
Group, its affiliates or sub-licensees of any product containing the in-licensed compounds.

20. Related parties transactions

As of December 31, 2017, the Group’s related parties include key management (Board of Directors and Executive
Committee) and members of their immediate families. The following transactions were carried out with related party:

Report on the audit of the consolidated financial statements

Opinion
We have audited the consolidated financial statements of ObsEva SA and its subsidiaries (the Group), which
comprise the consolidated balance sheet as at 31 December 2017 and the consolidated statement of
comprehensive loss, consolidated statement of cash flows and consolidated statement of changes in equity for
the year then ended, and notes to the consolidated financial statements, including a summary of significant
accounting policies.

In our opinion, the accompanying consolidated financial statements give a true and fair view of the consolidated
financial position of the Group as at 31 December 2017 and its consolidated financial performance and its
consolidated cash flows for the year then ended in accordance with the International Financial Reporting
Standards (IFRS), and comply with Swiss law.

Basis for opinion
We conducted our audit in accordance with Swiss law, International Standards on Auditing (ISAs) and Swiss
Auditing Standards. Our responsibilities under those provisions and standards are further described in the
“Auditor’s responsibilities for the audit of the consolidated financial statements” section of our report.

We are independent of the Group in accordance with the provisions of Swiss law and the requirements of the
Swiss audit profession, as well as the IESBA Code of Ethics for Professional Accountants, and we have fulfilled
our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we
have obtained is sufficient and appropriate to provide a basis for our opinion.

Our audit approach

Overview

Overall Group materiality: USD 672,000

We performed full scope audit work at the Group’s Swiss entity. Our
audit scope at this entity addressed 95% of the Group's total
operating expenses, and 100% of total assets. In addition, specified
procedures were performed at the Group’s entity in the United
States of America, representing the remaining 5% of the Group's
total operating expenses.

As key audit matter the following area of focus has been identified:

- Carrying value of intangible assets

ObsEva S.A. - Annual Report 2017

Consolidated IFRS Financial Statements for the year ended December 31, 2017
Report of the Statutory Auditor to the General Meeting

Audit scope
We tailored the scope of our audit in order to perform sufficient work to enable us to provide an opinion on the
consolidated financial statements as a whole, taking into account the structure of the Group, the accounting
processes and controls, and the industry in which the Group operates.

The Group is comprised of three entities located in three different countries, namely Switzerland, the United
States of America (US) and Ireland. The Group financial statements are a consolidation of these three entities,
with the Irish entity being inactive, comprising the Group's operating business and centralised functions. Based
on the client's operations we have performed full scope audit work on the Swiss entity, and specified procedures
on the US entity.

Materiality
The scope of our audit was influenced by our application of materiality. Our audit opinion aims to provide
reasonable assurance that the consolidated financial statements are free from material misstatement.
Misstatements may arise due to fraud or error. They are considered material, if individually or in aggregate, they
could reasonably be expected to influence the economic decisions of users taken on the basis of the consolidated
financial statements.

Based on our professional judgement, we determined certain quantitative thresholds for materiality, including
the overall Group materiality for the consolidated financial statements as a whole as set out in the table below.
These, together with qualitative considerations, helped us to determine the scope of our audit and the nature,
timing and extent of our audit procedures and to evaluate the effect of misstatements, both individually and in
aggregate, on the consolidated financial statements as a whole.

Overall Group materiality

USD 672,000

How we determined it

1% of total expenses

Rationale for the materiality
benchmark applied

Profit before tax is not considered an appropriate benchmark as the
Group is a start-up still in the developmental phase, and has no
recurring revenue. Based on the nature of the Group we determined
total expenses as the most appropriate benchmark, applying a 1%
rule of thumb.

We agreed with the Audit Committee that we would report to them misstatements above USD 67,000 identified
during our audit as well as any misstatements below that amount which, in our view, warranted reporting for
qualitative reasons.

Key audit matters
Key audit matters are those matters that, in our professional judgement, were of most significance in our audit
of the consolidated financial statements of the current period. These matters were addressed in the context of
our audit of the consolidated financial statements as a whole, and in forming our opinion thereon, and we do not
provide a separate opinion on these matters.

Carrying value of intangible assets

Key audit matter

How our audit addressed the key audit matter

The Group has intangible assets totaling USD 21.6
million at December 31, 2017 comprised of
licenses to operate several biopharmaceutical
product candidates. The Group is required to
review its intangibles for impairment whenever
events or changes in circumstances indicate that

We assessed factors that could trigger indications

that a potential impairment may exist by
performing a review of the minutes of
Management, Board of Directors and Board
Committee meetings, external communications,
including press releases and other public filings,

ObsEva S.A. - Annual Report 2017

Consolidated IFRS Financial Statements for the year ended December 31, 2017
Report of the Statutory Auditor to the General Meeting

their carrying amounts may not be recoverable,
and at least annually. As part of such review, the
Group did not identify any impairment.

public communications coming from direct
competitors, and consideration of the results of
subsequent event procedures performed.

We focused on the carrying value of intangible
assets as these assets are significant to the Group
and relate to licenses that haven’t yet received
regulatory and marketing approvals. As a result,
these assets rely on future cash flows expected to
be derived from the successful development and
commercialization of the various
biopharmaceutical product candidates. As such,
management’s impairment assessment includes
significant assumptions subject to judgment, such
as determining the probabilities of achieving
development milestones based on industry
standards, expected market share, life of the
assets, and the discount rate.

Refer to Note 2 Significant accounting policies
(page 76) and Note 8 Intangible assets (page 84).

We assessed the reasonableness of the valuation
model used by management to determine the
recoverable amounts of the intangible assets, and
reviewed the consistency of the current-year’s
significant assumptions with prior periods.

We assessed management’s sensitivity analysis
around key estimates to quantify the downside
changes in assumptions that could result in an
impairment and the disclosures included in Note
8 Intangible assets (page 84) of the annual report.

We reviewed management’s assessment on each of
the qualitative factors, including those associated
with timely and successful completion of clinical
trials and subsequent approval, and corroborated
management’s explanation to the underlying
documentation and market information.

On the basis of the above procedures performed
we did not identify any triggering event that would
potentially challenge the Group’s carrying value of
intangible assets, nor did we identify any factors
that would indicate any management bias existed
in the significant assumptions used. As such, we
found the assessment made by the Group in its
determination that no impairment existed in the
carrying value of intangible assets was based upon
reasonable assumptions, consistently applied.

Other information in the annual report
The Board of Directors is responsible for the other information in the annual report. The other information
comprises all information included in the annual report, but does not include the consolidated financial
statements, the stand-alone financial statements and the remuneration report of ObsEva SA and our auditor’s
reports thereon.

Our opinion on the consolidated financial statements does not cover the other information in the annual report
and we do not express any form of assurance conclusion thereon.

In connection with our audit of the consolidated financial statements, our responsibility is to read the other
information in the annual report and, in doing so, consider whether the other information is materially
inconsistent with the consolidated financial statements or our knowledge obtained in the audit, or otherwise
appears to be materially misstated. If, based on the work we have performed, we conclude that there is a
material misstatement of this other information, we are required to report that fact. We have nothing to report
in this regard.

Responsibilities of the Board of Directors for the consolidated financial statements
The Board of Directors is responsible for the preparation of the consolidated financial statements that give a true
and fair view in accordance with IFRS and the provisions of Swiss law, and for such internal control as the Board
of Directors determines is necessary to enable the preparation of consolidated financial statements that are free
from material misstatement, whether due to fraud or error.

ObsEva S.A. - Annual Report 2017

100

Consolidated IFRS Financial Statements for the year ended December 31, 2017
Report of the Statutory Auditor to the General Meeting

In preparing the consolidated financial statements, the Board of Directors is responsible for assessing the
Group’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and
using the going concern basis of accounting unless the Board of Directors either intends to liquidate the Group
or to cease operations, or has no realistic alternative but to do so.

Auditor’s responsibilities for the audit of the consolidated financial statements
Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a
whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that
includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit
conducted in accordance with Swiss law, ISAs and Swiss Auditing Standards will always detect a material
misstatement when it exists. Misstatements can arise from fraud or error and are considered material if,
individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users
taken on the basis of these consolidated financial statements.

As part of an audit in accordance with Swiss law, ISAs and Swiss Auditing Standards, we exercise professional
judgment and maintain professional scepticism throughout the audit. We also:

•

Identify and assess the risks of material misstatement of the consolidated financial statements, whether
due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit
evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a
material misstatement resulting from fraud is higher than for one resulting from error, as fraud may
involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.
Obtain an understanding of internal control relevant to the audit in order to design audit procedures
that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Group’s internal control.
Evaluate the appropriateness of accounting policies used and the reasonableness of accounting
estimates and related disclosures made.
Conclude on the appropriateness of the Board of Directors’ use of the going concern basis of accounting
and, based on the audit evidence obtained, whether a material uncertainty exists related to events or
conditions that may cast significant doubt on the Group’s ability to continue as a going concern. If we
conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to
the related disclosures in the consolidated financial statements or, if such disclosures are inadequate, to
modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our
auditor’s report. However, future events or conditions may cause the Group to cease to continue as a
going concern.
Evaluate the overall presentation, structure and content of the consolidated financial statements,
including the disclosures, and whether the consolidated financial statements represent the underlying
transactions and events in a manner that achieves fair presentation.
Obtain sufficient appropriate audit evidence regarding the financial information of the entities or
business activities within the Group to express an opinion on the consolidated financial statements. We
are responsible for the direction, supervision and performance of the Group audit. We remain solely
responsible for our audit opinion.

We communicate with the Board of Directors or its relevant committee regarding, among other matters, the
planned scope and timing of the audit and significant audit findings, including any significant deficiencies in
internal control that we identify during our audit.

We also provide the Board of Directors or its relevant committee with a statement that we have complied with
relevant ethical requirements regarding independence, and to communicate with them all relationships and
other matters that may reasonably be thought to bear on our independence, and where applicable, related
safeguards.

From the matters communicated with the Board of Directors or its relevant committee, we determine those
matters that were of most significance in the audit of the consolidated financial statements of the current period
and are therefore the key audit matters. We describe these matters in our auditor’s report

ObsEva S.A. - Annual Report 2017

101

Consolidated IFRS Financial Statements for the year ended December 31, 2017
Report of the Statutory Auditor to the General Meeting

unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances,
we determine that a matter should not be communicated in our report because the adverse consequences of
doing so would reasonably be expected to outweigh the public interest benefits of such communication.

Report on other legal and regulatory requirements

In accordance with article 728a paragraph 1 item 3 CO and Swiss Auditing Standard 890, we confirm that an
internal control system exists which has been designed for the preparation of consolidated financial statements
according to the instructions of the Board of Directors.

We recommend that the consolidated financial statements submitted to you be approved.

ObsEva S.A. - Annual Report 2017

105

Statutory Financial Statements of ObsEva S.A. for the year ended December 31, 2017

Notes to the Financial Statements 2017

1. General information

ObsEva Ltd was founded on 14 November 2012 in Geneva, Switzerland, and is domiciled 12 chemin des Aulx, 1228 Plan-
les-Ouates. The purpose of the Company is all activities and services in the domains of research, development, fabrication,
registration, promotion and commercialization of biotechnological and pharmaceutical products.

These statutory financial statements were authorized for issue by the Company’s Board of Directors on April 6, 2018.

2. Accounting principles applied in the preparation of the financial statements

These financial statements have been prepared in accordance with the provisions of commercial accounting as set out in the
Swiss Code of Obligations (Art. 957 to 963b CO, effective since 1 January 2013). Significant balance sheet items are
accounted for as follows:

• Current assets

Other current receivables are carried at their nominal value. Impairment charges are calculated for these assets on
an individual basis.

• Non-current assets

Property, plant and equipment is carried at cost less depreciation. Depreciation is calculated using the straight-line
method, on the basis of the following useful lives:
- furniture
- hardware
- leasehold improvement
Property, plant and equipment and intangible assets are reviewed for impairment whenever events or changes in
circumstances indicate that their carrying amount may not be recoverable, on an individual basis. An impairment
loss is recognized for the amount by which the asset's carrying amount exceeds its recoverable amount.

5 years
3 years
duration of lease

• Recognition of income

Income is recognised if its amount can be reliably measured and it is sufficiently probable that the economic benefits
will flow to the company.

• Foreign currencies

Monetary and non-monetary items in foreign currency are translated into the company functional currency as
follows:
- the exchange rates used for balance sheet items are the rates prevailing on 31 December;
- the exchange rates used for transactions conducted during the course of the year and for items in the profit and loss
statement are the exchange rates prevailing at the dates of the transactions or valuations where items are re-measured.

Until December 31, 2016, the functional currency of the company was the Swiss franc (CHF). As from January 1,
2017, due to a change of its primary economic environment, the functional currency of ObsEva SA became the US
dollar (USD). Values in Swiss franc presented in accordance with Art. 958d of the Swiss code of Obligations were
converted from the functional currency as follows:

USD/CHF prevailing rate

Report on the audit of the financial statements

Opinion
We have audited the financial statements of ObsEva SA, which comprise the balance sheet as at 31 December
2017, statement of loss and notes for the year then ended, including a summary of significant accounting
policies.

In our opinion, the accompanying financial statements as at 31 December 2017 comply with Swiss law and the
company’s articles of incorporation.

Basis for opinion
We conducted our audit in accordance with Swiss law and Swiss Auditing Standards. Our responsibilities under
those provisions and standards are further described in the “Auditor’s responsibilities for the audit of the
financial statements” section of our report.

We are independent of the entity in accordance with the provisions of Swiss law and the requirements of the
Swiss audit profession and we have fulfilled our other ethical responsibilities in accordance with these
requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a
basis for our opinion.

Our audit approach

Overview

Overall materiality: USD 588,000

We tailored the scope of our audit in order to perform sufficient
work to enable us to provide an opinion on the financial statements
as a whole, taking into account the structure of the entity, the
accounting processes and controls, and the industry in which the
entity operates.

As key audit matter the following area of focus has been identified:

- Carrying value of intangible assets

Audit scope
We designed our audit by determining materiality and assessing the risks of material misstatement in the
financial statements. In particular, we considered where subjective judgements were made; for example,

ObsEva S.A. - Annual Report 2017

113

Statutory Financial Statements of ObsEva S.A. for the year ended December 31, 2017
Report of the Statutory Auditor to the General Meeting

in respect of significant accounting estimates that involved making assumptions and considering future events
that are inherently uncertain. As in all of our audits, we also addressed the risk of management override of
internal controls, including among other matters consideration of whether there was evidence of bias that
represented a risk of material misstatement due to fraud.

Materiality
The scope of our audit was influenced by our application of materiality. Our audit opinion aims to provide
reasonable assurance that the financial statements are free from material misstatement. Misstatements may
arise due to fraud or error. They are considered material if, individually or in aggregate, they could reasonably
be expected to influence the economic decisions of users taken on the basis of the financial statements.

Based on our professional judgement, we determined certain quantitative thresholds for materiality, including
the overall materiality for the financial statements as a whole as set out in the table below. These, together with
qualitative considerations, helped us to determine the scope of our audit and the nature, timing and extent of
our audit procedures and to evaluate the effect of misstatements, both individually and in aggregate, on the
financial statements as a whole.

Overall materiality

USD 588,000

How we determined it

1% of total expenses

Rationale for the materiality
benchmark applied

Profit before tax is not considered an appropriate benchmark as the
entity is a start-up, still in the developmental phase, and has no
recurring revenue. Based on the nature of the entity we determined
total expenses as the most appropriate benchmark, applying a 1%
rule of thumb.

We agreed with the Audit Committee that we would report to them misstatements above USD 59,000 identified
during our audit as well as any misstatements below that amount which, in our view, warranted reporting for
qualitative reasons.

Report on key audit matters based on the circular 1/2015 of the Federal Audit Oversight
Authority
Key audit matters are those matters that, in our professional judgement, were of most significance in our audit
of the financial statements of the current period. These matters were addressed in the context of our audit of the
financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion
on these matters.

Carrying value of intangible assets

Key audit matter

How our audit addressed the key audit matter

The entity has intangible assets totaling USD 19.5
million at December 31, 2017 comprised of
licenses to operate several biopharmaceutical
product candidates. The entity is required to
review its intangibles for impairment whenever
events or changes in circumstances indicate that
their carrying amounts may not be recoverable,
and at least annually. As part of such review, the
entity did not identify any impairment.

We assessed factors that could trigger indications
that a potential impairment may exist by per-
forming a review of the minutes of Management,
Board of Directors and Board Committee
meetings, external communications, including
press releases and other public filings, public
communications coming from direct competitors,
and consideration of the results of subsequent
event procedures performed.

ObsEva S.A. - Annual Report 2017

114

Statutory Financial Statements of ObsEva S.A. for the year ended December 31, 2017
Report of the Statutory Auditor to the General Meeting

We focused on the carrying value of intangible
assets as these assets are significant to the entity
and relate to licenses that haven’t yet received
regulatory and marketing approvals. As a result,
these assets rely on future cash flows expected to
be derived from the successful development and
commercialization of the various
biopharmaceutical product candidates. As such,
management’s impairment assessment includes
significant assumptions subject to judgment, such
as deter-mining the probabilities of achieving
development milestones based on industry
standards, expected market share, life of the
assets, and the discount rate.

Refer to Note 2 Significant accounting policies
(page 106) and Note 7 Intangible assets (page
108).

We assessed management’s sensitivity analysis
around key estimates, to quantify the downside
changes in assumptions that could result in an
impairment.

On the basis of the above procedures performed
we did not identify any triggering event that would
potentially challenge the entity’s carrying value of
intangible assets, nor did we identify any factors
that would indicate any management bias existed
in the significant assumptions used. As such, we
found the assessment made by the entity in its
determination that no impairment existed in the
carrying value of intangible assets was based upon
reasonable assumptions, consistently applied.

Responsibilities of the Board of Directors for the financial statements
The Board of Directors is responsible for the preparation of the financial statements in accordance with the
provisions of Swiss law and the company’s articles of incorporation, and for such internal control as the Board of
Directors determines is necessary to enable the preparation of financial statements that are free from material
misstatement, whether due to fraud or error.

In preparing the financial statements, the Board of Directors is responsible for assessing the entity’s ability to
continue as a going concern, disclosing, as applicable, matters related to going concern and using the going
concern basis of accounting unless the Board of Directors either intends to liquidate the entity or to cease
operations, or has no realistic alternative but to do so.

Auditor’s responsibilities for the audit of the financial statements
Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free
from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our
opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in
accordance with Swiss law and Swiss Auditing Standards will always detect a material misstatement when it
exists. Misstatements can arise from fraud or error and are considered material if, individually or in the
aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of
these financial statements.

As part of an audit in accordance with Swiss law and Swiss Auditing Standards, we exercise professional
judgment and maintain professional scepticism throughout the audit. We also:

•

Identify and assess the risks of material misstatement of the financial statements, whether due to fraud or
error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is
sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material
misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve
collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

ObsEva S.A. - Annual Report 2017

115

Statutory Financial Statements of ObsEva S.A. for the year ended December 31, 2017
Report of the Statutory Auditor to the General Meeting

• Obtain an understanding of internal control relevant to the audit in order to design audit procedures that

are appropriate in the circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the entity’s internal control.

• Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates

and related disclosures made.

• Conclude on the appropriateness of the Board of Directors’ use of the going concern basis of accounting
and, based on the audit evidence obtained, whether a material uncertainty exists related to events or
conditions that may cast significant doubt on the entity’s ability to continue as a going concern. If we
conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to
the related disclosures in the financial statements or, if such disclosures are inadequate, to modify our
opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report.
However, future events or conditions may cause the entity to cease to continue as a going concern.

From the matters communicated with the Board of Directors or its relevant committee, we determine those
matters that were of most significance in the audit of the financial statements of the current period and are
therefore the key audit matters. We describe these matters in our auditor’s report unless law or regulation
precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a
matter should not be communicated in our report because the adverse consequences of doing so would
reasonably be expected to outweigh the public interest benefits of such communication.

Report on other legal and regulatory requirements

In accordance with article 728a paragraph 1 item 3 CO and Swiss Auditing Standard 890, we confirm that an
internal control system exists which has been designed for the preparation of financial statements according to
the instructions of the Board of Directors.

We recommend that the financial statements submitted to you be approved.

Compensation Report
of ObsEva S.A.
for the year ended December 31, 2017

ObsEva S.A. - Annual Report 2017

117

Compensation Report of ObsEva S.A. for the year ended December 31, 2017

This compensation report has been prepared in accordance with the Federal Ordinance Against Excessive Compensation in
Stock Exchange Listed Companies (“Ordinance”), effective as from January 1, 2014. The Ordinance is applicable to
ObsEva SA (the “Company”) as from its initial public offering in January 2017.

A – GUIDING PRINCIPLES

The Company’s articles of association, organizational regulations and policies provide the basis for the principles of
compensation (the “Compensation Policy”). The Board of Directors (the “Board”) is responsible for establishing
Compensation Policy guidelines within the group.

The term “compensation” shall have the meaning set forth in Article 14 of the Ordinance, or any successor legislation, and
shall include, without limitation, salary, long-term incentives, bonuses, perquisites, equity incentives, severance
arrangements (to the extent permitted by applicable law), retirement benefits and other related benefits and benefit plans.

The Company’s Compensation Policy is designed to attract, motivate, and retain well-qualified employees and gain new,
highly skilled staff, in order to support the achievement of the Company’s strategic objectives. The compensation package
must be fair and competitive, and the Company uses the services of a reputable, independent expert firm to assess the
appropriateness of its compensation level and structure for its Board members and executive officers. The individual
overall compensation takes into account the individual’s professional skills, engagement and personal performance. It is
made up of short-term compensation components, which are generally paid in cash, and long-term compensation
components, generally in the form of a participation to an equity incentive plan.

B – ORGANISATION AND COMPETENCIES

Subject to the powers of the general meeting of shareholders, the Board determines the compensation of its members and of
the members of the Executive Committee (the “ExCom”), in accordance with the Company’s Compensation Policy, on the
recommendation of the Compensation, Nominating and Corporate Governance Committee (the “Committee”).
The Committee is composed of two or more members of the Board who have been individually elected by the general
meeting of shareholders, for a term of one year, until the end of the next annual general meeting. If the Committee is not
complete, the Board nominates the missing members for the remaining period of office. The Board elects the chair from the
members of the Committee. Members of the Committee are eligible for re-election indefinitely.

The Committee supports the Board in establishing and reviewing the Company’s compensation strategy, guidelines and the
performance targets. The Committee reviews and makes recommendations to the Board regarding (i) the compensation to
be paid to the members of the Board and the members of the ExCom, and (ii) the proposals to be made to the general
meeting of shareholders regarding such compensation, as required under Swiss law. In its review process, the Committee
considers compensation packages of other companies in the biotech and pharmaceutical industry that are comparable to
ObsEva, with respect to size, listing place or business model, the professional experience and areas of responsibility of the
respective members. Such benchmark is conducted by a reputable, independent expert firm that assesses the
appropriateness of the Company’s compensation level and structure. The Committee may also submit proposals to the
Board in other compensation-related issues.

Based on the Committee’s recommendations, the Board submits two proposals for approval at the shareholders meeting: (i)
the maximum aggregate compensation for the members of the Board until the next annual general meeting; and (ii) the
maximum aggregate compensation for the members of the ExCom for the following business year. The approval of these
proposals requires an absolute majority (50% plus one) of the vote cast at the shareholders meeting.

If the general meeting of shareholders does not approve a compensation proposal made by the Board, the Board convenes
an extraordinary general meeting of shareholders. Compensation may be paid out prior to their approval by the general
meeting of shareholders, subject to their subsequent approval by the general meeting of shareholders and, in the absence of
such subsequent approval, to restitution to the Company. If the maximum aggregate amount of compensation already
approved by the general meeting of shareholders is not sufficient to also cover the compensation of one or more persons
who became members of the ExCom during a compensation period for which the general meeting of shareholders has
already approved the compensation of the ExCom (new hire), the Company is authorized to pay an additional amount with
respect to the compensation period already approved. Such additional amount cannot exceed (i) for the head of the ExCom
(CEO), 140% of the total annual compensation of the former CEO and (ii) for any new hire other than the CEO, 140% of
the highest total annual compensation of any member of the ExCom in office other than the CEO.

C – COMPENSATION COMPONENTS

Board of Directors Members Annual Cash Compensation

Each member of the Board who is not also serving as an employee of the Company or/and of its affiliates, receives an
annual fixed cash compensation, payable in quarterly installments, as set forth below:

1 - Annual Board service retainer:

a) Chairman of the Board $ 70,000
b) All other eligible members of the Board $ 40,000

2 - Annual committee member service retainer:

a) Member of the Audit Committee $ 7,500
b) Member of the Compensation, Nominating and Corporate Governance Committee $ 7,500

3 - Annual committee chair service retainer (in addition to committee member service retainer)

a) Chair of the Audit Committee $ 7,500
b) Chair of the Compensation, Nominating and Corporate Governance Committee $ 7,500

Social contributions, to the extent required by Swiss law, are accrued on the annual cash compensation of the Board and
committee’s members.

In addition, the Company reimburses Board members for out-of-pocket expenses incurred in relation to their services on an
on-going basis upon presentation of the corresponding receipts. Expenses reimbursements are not part of the compensation.

Pursuant to organizational regulations of the Board, members of the Board who are also serving as an employee of the
Company or/and of its affiliates only receive compensation in their capacity as employees and do not receive additional
compensation for their activities as members of the Board.

Executive Committee Members Annual Cash Compensation

The annual cash compensation of the members of the ExCom consists of fixed and variable compensation elements. Fixed
compensation comprises the base salary and other compensation elements. Variable compensation comprises performance-
related cash bonuses. The total compensation takes into account position and level of responsibility of the recipient.

Variable annual cash compensation elements are governed by performance metrics that take into account the performance
of the Company and some or all of its subsidiaries, market performance, other companies or comparable benchmarks
and/or individual quantitative and qualitative performance targets. The Committee determines the performance metrics, the
target levels as well as their achievement.

Social contributions, to the extent required by Swiss law, are accrued on the annual cash compensation of the ExCom
members.

In addition, the Company reimburses ExCom members for out-of-pocket expenses incurred in relation to their services on
an on-going basis upon presentation of the corresponding receipts. Expenses reimbursements are not part of the
compensation.

Equity incentive plans

The Company has established two equity incentive plans, in 2013 (the “2013 EIP”) and 2017 (the “2017 EIP”).

The purpose of the Company’s 2013 EIP and 2017 EIP is to provide members of the Board, members of the ExCom,
employees and certain consultants (the “Beneficiaries”) with an opportunity to benefit from the potential appreciation in the
value of the Company’s shares, thus providing an increased incentive for participants to contribute to the future success and
prosperity of the Company, enhancing the value of the shares for the benefit of the shareholders of the Company and
increasing the ability of the Company to attract and retain individuals of exceptional skill. In addition, these plans provide
the Company with a mechanism to engage services for non-cash consideration.

ObsEva S.A. - Annual Report 2017

119

Compensation Report of ObsEva S.A. for the year ended December 31, 2017

Under 2013 EIP, the Company has granted the Beneficiaries non-voting shares that were converted into common shares
upon completion of the Company’s initial public offering in January 2017. The Company has stopped granting equity
instruments under the 2013 EIP in 2016. Under 2017 EIP, the Company has been granting stock-options to the
Beneficiaries.

The grant of equity instruments under 2013 EIP or 2017 EIP is at the discretion of the Board, the Committee or the ExCom,
depending of the delegation of competences. Key factors considered by the Board, the Committee or the ExCom in making
grants of equity instruments are the amount of outstanding authorized or conditional share capital approved by
shareholders, the benchmarking with other companies as well as individual performance of the Beneficiaries. The Board,
the Committee or the ExCom, depending on the delegation of competences, determines grant, vesting, exercise and
forfeiture conditions. In particular, they may provide for continuation, acceleration or removal of vesting and exercise
conditions, for payment or grant of compensation based upon assumed target achievement, or for forfeiture, in each case in
the event of pre-determined events such as a change-of-control or termination of an employment or mandate agreement.
The Company may procure the required shares through purchases in the market, either directly or through companies
controlled by it, or by issuing new shares.

The Board has the authority to amend 2013 EIP and 2017 EIP.

Indirect benefits

The Company contributes to pension contributions and maintains certain insurance for death and invalidity for the members
of the ExCom in accordance with the regulations applicable to the pension schemes in which the Company or any of it
subsidiary participate.

Loans, credits and guarantees

Subject to vote of the general meeting of shareholders on compensation proposals, which is binding, the Company does not
grant loans or credit facilities to members of the Board or members of the ExCom.

Plan-les-Ouates

We have audited the accompanying remuneration report of ObsEva SA for the year ended 31 December 2017. The
audit was limited to the information according to articles 14–16 of the Ordinance against Excessive Compensation
in Stock Exchange Listed Companies (Ordinance) contained in the sections labeled 'audited' on pages 120 to 122
of the remuneration report.

Board of Directors’ responsibility
The Board of Directors is responsible for the preparation and overall fair presentation of the remuneration report
in accordance with Swiss law and the Ordinance against Excessive Compensation in Stock Exchange Listed
Companies (Ordinance). The Board of Directors is also responsible for designing the remuneration system and
defining individual remuneration packages.

Auditor’s responsibility
Our responsibility is to express an opinion on the accompanying remuneration report. We conducted our audit in
accordance with Swiss Auditing Standards. Those standards require that we comply with ethical requirements
and plan and perform the audit to obtain reasonable assurance about whether the remuneration report complies
with Swiss law and articles 14–16 of the Ordinance.

An audit involves performing procedures to obtain audit evidence on the disclosures made in the remuneration
report with regard to compensation, loans and credits in accordance with articles 14–16 of the Ordinance. The
procedures selected depend on the auditor’s judgment, including the assessment of the risks of material
misstatements in the remuneration report, whether due to fraud or error. This audit also includes evaluating the
reasonableness of the methods applied to value components of remuneration, as well as assessing the overall
presentation of the remuneration report.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our
opinion.

Opinion

In our opinion, the remuneration report of ObsEva SA for the year ended 31 December 2017 complies with Swiss
law and articles 14–16 of the Ordinance.
