CEO’S LETTER

Dear Fellow 
Shareholders —

2016
Key Events
and Milestones

JANUARY

Halozyme completed $150M 
royalty-backed debt deal

MARCH

The first patient is dosed 
in HALO-301, the phase 3 
clinical trial of PEGPH20 in 
combination with ABRAXANE® 
and gemcitabine.

Shire launched a pediatric 
indication of HYQVIA® in eight 
European countries to treat 
primary and certain secondary 
immunodeficiencies, following a 
marketing authorization granted 
by the European Commission in 
May. HYQVIA is co-administered 
with the ENHANZE™ platform.

JUNE

Roche initiated a phase 1 
clinical trial with PERJETA® in 
combination with ENHANZE™  
for HER-2 positive breast  
cancer patients.

JULY

Eisai and Halozyme initiated a 
phase 1b/2 clinical trial with first 
patient dosing of HALAVEN® in 
combination with PEGPH20. 

Our team enters the year with great 
momentum and confidence, supported by 
the progress we made in 2016 and the clear 
opportunities we see ahead in 2017 and 
beyond. We continue to execute against our 
two-pillar strategy, built on our proprietary 
rHuPH20 enzyme, which is the foundation 
of both our ENHANZE™ platform and our 
investigational oncology drug, PEGPH20.

In the oncology pillar, we were pleased 
to recently announce results of our phase 2 
HALO-202 study. As of December 2016, the 
study showed that PEGPH20 in combination 
with ABRAXANE® (nab-paclitaxel) and 
gemcitabine in advanced pancreas cancer 
patients met its primary endpoints. The 
study showed a statistically significant 
improvement in progression-free survival 
(PFS) in all evaluable patients and a 
meaningful reduction in the thromboembolic 
event rate in the PEGPH20 treatment arm. 
Highly relevant to our ongoing HALO-301 
phase 3 study, HALO-202 also showed a 
statistically significant PFS improvement in 
patients with high levels of hyaluronan (HA). 
PEGPH20 temporarily degrades HA, a 
glycosaminoglycan or a chain of natural 
sugars in the body that can accumulate 
around certain tumor types and impede 
access of cancer therapies to the tumor. 
These results support the ongoing phase 3 
study we initiated in March 2016, where 
patients with high HA are being selected 
for inclusion.  

In addition to starting the phase 3 study, 

throughout 2016 we achieved a number of 
value enhancing goals and milestones in the 
PEGPH20 program, including:

• Receiving approval for an investigational 
device exemption (IDE) submitted to the 
FDA in February by our partner Ventana 
Medical Systems. The IDE allows Halozyme 
to use the co-developed investigational 
diagnostic assay in HALO-301 to 
prospectively identify HA-High patients 
for inclusion in the study.

• Dosing the first patient in a phase 1b/2 

Additional ENHANZE™ platform highlights in 

Overall, our ENHANZE platform continues to 

distinguish Halozyme and create great 

potential for future growth. 

Revenue for the year was $147 million, an 

8.6 percent increase over 2015, and we exited 

the year well-financed with $205 million  

in cash.   

  Throughout the year, we created 

long-term value for our shareholders as we 

advanced toward our goal to become a 

leading global oncology biotechnology 

company. Each day we make progress toward 

our goal, we strengthen a commitment to the 

patients we serve and those we may serve in 

the future. They remain the focus of all that 

we do.

Thank you for your continued support.

clinical trial led by our collaboration partner, 
Eisai, to determine whether HALAVEN®
Eisai, to determine whether HALAVEN®
Eisai, to determine whether HALAVEN
(eribulin mesylate) in combination with 
PEGPH20 can lead to an improvement in 
overall response rate as compared with 
eribulin alone as a therapy in women with 
advanced or metastatic, HA-High HER2-
negative breast cancer.

• Being selected for inclusion in the Precision 
Promise initiative, led by the Pancreatic 
Cancer Action Network. PEGPH20 and the 
Ventana co-developed investigational 
diagnostic assay for HA will be included in 
this large-scale trial in an unprecedented 
collaboration of clinicians, researchers and 
drug developers.   

• Entering into an agreement with Genentech, 

a member of the Roche Group, to 
collaborate on clinical studies evaluating 
PEGPH20 and TECENTRIQ® (atezolizumab) 
®
® (atezolizumab) 
in up to eight different tumor types. The 
studies are scheduled to begin in 2017.

• Expanding our phase 1b study of PEGPH20 

  Halozyme royalty revenue.

in combination with KEYTRUDA®
(pembrolizumab) in HA-High patients 
with advanced non-small cell lung and 
gastric cancers.    

We remain encouraged by the pan-tumor 
potential of PEGPH20 and seek to 
demonstrate this potential through the 
multiple clinical and investigator sponsored 
trials currently underway.

Our work in oncology is funded in part 
by the second pillar of our strategy.  The 
ENHANZE™ drug delivery platform removes 
traditional limitations on the volume of 
biologics and drugs that can be delivered 
by rapid subcutaneous administration. 
Global collaboration and licensing 
agreements with our six partners -- Roche, 
Shire/Baxalta, Pfizer, Janssen, AbbVie and 
Lilly -- generated more than $129 million 
in revenue.  

2016 included:

•  Royalty revenue growing 65 percent as three  

  partnered products from Shire and Roche  

  continue to increase use around the globe by  

  patients and health care practitioners.   

•  Acceptance by the FDA of Genentech’s  

  biologic license application for subcutaneous  

rituximab in non-Hodgkin’s lymphoma and  

  chronic lymphocytic leukemia. This co- 

formulation with our ENHANZE technology is  

  already approved and marketed under the  

  MabThera® SC brand in countries outside the  

  U.S. Including all approved indications, Roche  

reported total 2015 sales of rituximab in the  

  U.S. of approximately $3.5 billion and analysts  

  estimate the majority of these sales are blood  

  cancer related, making this one of the biggest  

  potential opportunities in ENHANZE franchise  

  history. Upon regulatory approvals, our royalty  

revenues will depend on the degree of market  

  penetration and indications, with the potential  

to create another significant inflection in  

•  Janssen presented compelling data from a  

  phase 1 trial of oncology drug daratumumab  

  with the ENHANZE platform indicating that,  

instead of a multi-hour intravenous infusion,  

  daratumumab may be delivered in  

  30 minutes with similar efficacy as a  

  subcutaneous administration. Analysts  

  estimate that sales of daratumumab may top  

  $7 billion by 2025. A phase 3 study is being  

  planned and Janssen recently took steps to  

  file for patent protection for the co-formulation.

•  During the year, Pfizer and AbbVie  

  discontinued three development projects  

  with the ENHANZE platform which, while  

  disappointing, can be expected in early stage  

  programs. We have very strong ongoing  

relationships with both companies. Pfizer  

  continues in development with one of their  

two remaining targets and AbbVie has nine  

targets under the agreement we formed  

in 2015.   

Throughout the 

year, we created 

long-term value for 

our shareholders 

as we advanced 

toward our goal to 

become a leading 

global oncology 

biotechnology 

company.

Item 1.  Business

Overview

PART I

Halozyme Therapeutics,  Inc.  is  a  biotechnology  company  focused  on  developing  and  commercializing  novel  oncology 
therapies. We are seeking to translate our unique knowledge of the tumor microenvironment to create therapies that have the 
potential to improve cancer patient survival. Our research primarily focuses on human enzymes that alter the extracellular matrix 
and tumor microenvironment. The extracellular matrix is a complex matrix of proteins and carbohydrates surrounding the cell that 
provides structural support in tissues and orchestrates many important biological activities, including cell migration, signaling and 
survival. Over many years, we have developed unique technology and scientific expertise enabling us to pursue this target-rich 
environment for the development of therapies.

Our proprietary enzymes are used to facilitate the delivery of injected drugs and fluids, potentially enhancing the efficacy 
and the convenience of other drugs or can be used to alter tissue structures for potential clinical benefit. We exploit our technology 
and expertise using a two pillar strategy that we believe enables us to manage risk and cost by: (1) developing our own proprietary 
products in therapeutic areas with significant unmet medical needs, with a focus on oncology, and (2) licensing our technology to 
biopharmaceutical companies to collaboratively develop products that combine our technology with the collaborators’ proprietary 
compounds.

The majority of our approved product and product candidates are based on rHuPH20, our patented recombinant human 
hyaluronidase enzyme. rHuPH20 is the active ingredient in our first commercially approved product, Hylenex® recombinant, and 
it works by temporarily breaking down hyaluronan (or HA), a naturally occurring complex carbohydrate that is a major component 
of the extracellular matrix in tissues throughout the body such as skin and cartilage. We believe this temporary degradation creates 
an opportunistic window for the improved subcutaneous delivery of injectable biologics, such as monoclonal antibodies and other 
large therapeutic molecules, as well as small molecules and fluids. We refer to the application of rHuPH20 to facilitate the delivery 
of other drugs or fluids as our ENHANZE™ Technology. We license the ENHANZE Technology to form collaborations with 

1

biopharmaceutical companies that develop or market drugs requiring or benefiting from injection via the subcutaneous route of 
administration.

We currently have ENHANZE collaborations with F. Hoffmann-La Roche, Ltd. and Hoffmann-La Roche, Inc. (Roche), 
Baxalta US Inc. and Baxalta GmbH (Baxalta Incorporated was acquired by Shire plc in June 2016) (Baxalta), Pfizer Inc. (Pfizer), 
Janssen Biotech, Inc. (Janssen), AbbVie, Inc. (AbbVie), and Eli Lilly and Company (Lilly). We receive royalties from two of these 
collaborations, including royalties from sales of one product approved in both the United States and outside the United States from 
the  Baxalta  collaboration  and  from  sales  of  two  products  approved  for  marketing  outside  the  United  States  from  the  Roche 
collaboration.  Future  potential  revenues  from  the  sales  and/or  royalties  of  our  approved  products,  product  candidates,  and 
ENHANZE collaborations will depend on the ability of Halozyme and our collaborators to develop, manufacture, secure and 
maintain regulatory approvals for approved products and product candidates and commercialize product candidates.

Our proprietary development pipeline consists primarily of pre-clinical and clinical stage product candidates in oncology. 
Our lead oncology program is PEGPH20 (PEGylated recombinant human hyaluronidase), a molecular entity we are developing 
in combination with currently approved cancer therapies as a candidate for the systemic treatment of tumors that accumulate HA. 
We have demonstrated that when HA accumulates in a tumor, it can cause higher pressure in the tumor, reducing blood flow into 
the tumor and with that, reduced access of cancer therapies to the tumor. PEGPH20 has been demonstrated in animal models to 
work by temporarily degrading HA surrounding cancer cells resulting in reduced pressure and increased blood flow to the tumor 
thereby enabling increased amounts of anticancer treatments administered concomitantly gaining access to the tumor. Through 
our efforts and efforts of our partners and collaborators, we are currently in Phase 2 and Phase 3 clinical testing for PEGPH20 
with ABRAXANE® (nab-paclitaxel) and gemcitabine in stage IV pancreatic ductal adenocarcinoma (PDA) (Studies 109-202 and 
109-301), in Phase 1b clinical testing for PEGPH20 with KEYTRUDA® (pembrolizumab) in non-small cell lung cancer and gastric 
cancer (Study 107-101) and in Phase 1b/2 clinical testing for PEGPH20 with HALAVEN® (eribulin) in patients treated with up 
to two lines of prior therapy for HER2-negative metastatic breast cancer.

Technology

rHuPH20 can be applied as a drug delivery platform to increase dispersion and absorption of other injected drugs and fluids 
that are injected under the skin or in the muscle thereby potentially enhancing efficacy or convenience. For example, rHuPH20 
has been used to convert drugs that must be delivered intravenously into subcutaneous injections or to reduce the number of 
subcutaneous injections needed for effective therapy. When ENHANZE Technology is applied subcutaneously, the rHuPH20 acts 
locally and has a tissue half-life of less than 15 minutes. HA at the local site reconstitutes its normal density within a few days 
and, therefore, we anticipate that any effect of rHuPH20 on the architecture of the subcutaneous space is temporary. 

Additionally, we are expanding our scientific work to develop other enzymes and agents that target the extracellular matrix’s 
unique aspects, giving rise to potentially new molecular entities with a particular focus on oncology. We are developing a PEGylated 
version of the rHuPH20 enzyme (PEGPH20), that lasts for an extended period in the bloodstream (half-life of one to two days), 
and may therefore better target solid tumors that accumulate HA by degrading the surrounding HA and reducing the interstitial 
fluid pressure within malignant tumors to allow better penetration by co-administered agents.

Strategy

During 2016, we continued our strategy of focusing on developing our oncology pipeline and expanding our collaborations 
for  ENHANZE  Technology.  This  business  model  allows  for  revenue  garnered  from  collaboration  products  to  help  fund  our 
investment in PEGPH20 clinical development, with the goal of a future product approval that will support sustained growth.

Key aspects of our corporate strategy include the following:

• 

• 

Focus on our oncology pipeline. We are currently developing PEGPH20, our investigational new drug candidate, 
in multiple different tumors that accumulate high levels of HA. PEGPH20 is in Phase 2 and Phase 3 development 
in stage IV PDA, in Phase 1b development in non-small cell lung cancer and gastric cancer and in Phase 1b/2 
development in patients treated with up to two lines of prior therapy for HER2-negative metastatic breast cancer. 
Over time, it is our goal to study additional types of cancer and to advance this program toward regulatory 
approval and commercial launch. In addition, we have two novel oncology preclinical assets. 

Focus on our ENHANZE platform. We currently have six collaborations with three current product approvals 
and additional product candidates in development. We intend to work with our existing collaborators to expand 
our collaborations to add new targets and product candidates under the terms of the operative agreements. In 
addition, we will continue our efforts to enter into new collaborations to further exploit and derive additional 
value from our proprietary technology.

Product and Product Candidates

We have one marketed proprietary product, three partnered products, one proprietary product candidate targeting several 
indications  in  various  stages  of  development,  and  two  preclinical  product  candidates.  The  following  table  summarizes  our 
proprietary product and product candidate as well as products and product candidates under development with our collaborators:

Proprietary Pipeline

Hylenex Recombinant (hyaluronidase human injection)

Hylenex recombinant is a formulation of rHuPH20 that has received U.S. Food and Drug Administration (FDA) approval to 
facilitate subcutaneous fluid administration for achieving hydration, to increase the dispersion and absorption of other injected 
drugs and, in subcutaneous urography, to improve resorption of radiopaque agents. Hylenex recombinant is currently the number 
one prescribed branded hyaluronidase. 

PEGPH20 

We  are  developing  PEGPH20  in  combination  with  currently  approved  cancer  therapies  as  a  candidate  for  the  systemic 
treatment of tumors that accumulate HA. ‘PEG’ refers to the attachment of polyethylene glycol to rHuPH20, thereby creating 
PEGPH20. One of the novel properties of PEGPH20 is that it lasts for an extended duration in the bloodstream and, therefore, can 
be administered systemically to maintain its therapeutic effect to treat disease.

Cancer malignancies, including pancreatic, lung, breast, gastric, colon and prostate cancers can accumulate high levels of 
HA and therefore we believe that PEGPH20 has the potential to help patients with these types of cancer when used with certain 
currently approved cancer therapies. Among solid tumors, PDA has been reported to be associated with the highest frequency of 
HA accumulation. There are approximately 65,000 annual diagnoses of PDA in the United States and the European Union, and 
we estimate that 35-40% have high levels of HA. 

The pathologic accumulation of HA, along with other matrix components, creates a unique microenvironment for the growth 
of  tumor  cells  compared  to  normal  cells. We  believe  that  depleting  the  HA  component  of  the  tumor  microenvironment  with 
PEGPH20 remodels the tumor microenvironment, resulting in tumor growth inhibition in animal models. Removal of HA from 
the tumor microenvironment results in expansion of previously constricted blood vessels allowing increased blood flow, potentially 
increasing  the  access  of  activated  immune  cells  and  factors  in  the  blood  into  the  tumor  microenvironment.  If  PEGPH20  is 
administered in conjunction with other anti-cancer therapies, the increase in blood flow may allow anti-cancer therapies to have 
greater access to the tumor, which may enhance the treatment effect of therapeutic modalities like chemotherapies, monoclonal 
antibodies and other agents.

We  are  developing  PEGPH20  as  a  targeted  therapy,  for  patients  who  have  tumors  with  high  levels  of  HA. We  have  a 
collaboration with Ventana Medical Systems Inc. (Ventana), a member of the Roche Group, to develop, and for Ventana to ultimately 
commercialize, a companion diagnostic assay for use with PEGPH20. The companion diagnostic assay is being used to identify 
high levels of HA in tumor biopsies, and may be the first diagnostic to target tumor-associated HA and possibly the first companion 
diagnostic assay in pancreatic cancer.

Pancreatic cancer indications:

Study Halo 109-201:

In January 2015, we presented the final results from Study 109-201, a multi-center, international open label dose escalation 
Phase 1b clinical study of PEGPH20 in combination with gemcitabine for the treatment of patients with stage IV PDA at the 2015 
Gastrointestinal Cancers Symposium (also known as ASCO-GI meeting). This study enrolled 28 patients with previously untreated 
stage IV PDA. Patients were treated with one of three doses of PEGPH20 (1.0, 1.6 and 3.0 μg/kg twice weekly for four weeks, 
then weekly thereafter) in combination with gemcitabine 1000 mg/m2 administered intravenously. In this study, the confirmed 
overall response rate (complete response + partial response confirmed on a second scan as assessed by an independent radiology 
review) was 29 percent (7 of 24 patients) for those treated at therapeutic dose levels of PEGPH20 (1.6 and 3.0 μg/kg). Median 
progression-free survival (PFS) was 154 days (95% CI, 50-166) in the efficacy-evaluable population (n = 24). Among efficacy-
evaluable patients with baseline tumor HA staining (n = 17), the median PFS in patients with high baseline tumor HA staining 
(6/17 patients) was substantially longer, 219 days, than in the patients with low baseline tumor HA staining (11/17 patients), 108 
days. Median overall survival (OS) was 200 days (95% CI, 123-370) in the efficacy-evaluable population (n = 24). Among efficacy-
evaluable patients with baseline tumor HA staining (n = 17), the median OS in patients with high baseline tumor HA staining (6/17 
patients) was substantially longer, 395 days, than in the patients with low baseline tumor HA staining (11/17 patients), 174 days. 
The most common treatment-emergent adverse events (occurring in  15% of patients) were peripheral edema, muscle spasms, 
thrombocytopenia, fatigue, myalgia, anemia, and nausea. Thromboembolic (TE) events were reported in 8 patients (28.6%) and 
musculoskeletal events were reported in 21 patients (75%) which were generally grade 1/2 in severity.

Study Halo 109-202:

In the second quarter of 2013, we initiated Study 109-202, a Phase 2 multicenter randomized clinical trial evaluating PEGPH20 
as a first-line therapy for patients with stage IV PDA. The study was designed to enroll patients who would receive gemcitabine 
and nab-paclitaxel (ABRAXANE®) either with or without PEGPH20. The primary endpoint is to measure the improvement in 
PFS  in  patients  receiving  PEGPH20  plus  gemcitabine  and ABRAXANE  (PAG  arm)  compared  to  those  who  are  receiving 
gemcitabine and ABRAXANE alone (AG arm). In April 2014, after 146 patients had been enrolled, the trial was put on clinical 
hold by Halozyme and the FDA to assess a question raised by the Data Monitoring Committee regarding a possible difference in 
the TE events rate between the group of patients treated in the PAG arm versus the group of patients treated in the AG arm. This 
portion of the study and patients in this portion are now referred to as Stage 1. At the time of the clinical hold all patients remaining 
in the study continued on gemcitabine and ABRAXANE. In July 2014, Study 109-202 was reinitiated (Stage 2) under a revised 
protocol,  which  excludes  patients  that  are  expected  to  be  at  a  greater  risk  for  TE  events.  The  revised  protocol  provides  for 
thromboembolism prophylaxis of all patients in both arms of the study with low molecular weight heparin, and adds evaluation 
of the TE events rate in Stage 2 PEGPH20-treated patients as a co-primary end point. Stage 2 of Study 109-202 enrolled an 
additional 133 patients, to add to the 146 patients already in the clinical trial, with a 2:1 randomization for the PAG arm compared 
to the AG arm. 

In March 2016, our partner Ventana received approval for an investigational device exemption (IDE) application from the 
FDA for our companion diagnostic test to enable patient selection in our Phase 3 Study 301 of PEGPH20 in HA-High patients. 
Based on the cutpoint for the Ventana diagnostic, we expect approximately 35 to 40 percent of stage IV PDA patients to have HA-
High tumors, similar to the previously reported interim results from Stage 1 of Study 202 using the Halozyme prototype assay.

In January 2017, we announced topline results from the combined analysis of Stage 1 and Stage 2, and Stage 2 alone, based 
on a December 2016 data cutoff. The combined analysis included 135 treated patients in Stage 1, of whom a total of 45 patients 
(25 in the PAG arm and 21 in the AG arm) were determined to have high HA, and 125 treated patients in Stage 2, of whom a total 
of 35 patients (24 in the PAG arm and 11 in the AG arm) were determined to have high HA. This analysis of secondary and 
exploratory endpoints was conducted using the Ventana companion diagnostic to prospectively identify high levels of HA. The 
key results showed in the combined Stage 1 and Stage 2 dataset:

•  The primary endpoint of PFS in the efficacy evaluable population (total of 231 patients) was met with statistical significance 
with a median PFS of 6.0 months in the PAG arm compared to 5.3 months in the AG arm, hazard ratio (HR) with a 95% 
confidence interval (CI):  0.73 (0.53, 1.00); p=0.048;

•  The secondary endpoint of PFS in the HA-High intent to treat population (total of 84 HA-High patients) was met with 
statistical significance with a median PFS of 9.2 months in the PAG arm compared to 5.2 months in the AG arm, HR 0.51 
(95% CI:  0.26, 1.00); p=0.048;

6

•  The exploratory analysis of median OS was 11.5 months vs. 8.5 months in the PAG vs. AG arms, respectively. Factors 
potentially having an impact on these results include less aggressive disease among patients in the AG arm within the 
Stage 1 patient population, and 9 of the 24 patients in the PAG arm (approximately 40 percent) discontinued PEGPH20 
treatment at the time of the clinical hold, resulting in many patients receiving AG alone in both arms.

In the Stage 2 cohort population, in a total of 35 HA-High patients, the key results showed:

•  Median PFS was 8.6 months in the PAG arm compared to 4.5 months in the AG arm, hazard ratio of 0.63 (95% CI:  0.21, 

1.93);

•  Median overall survival (OS) was 11.7 months in the PAG arm compared to 7.8 months in the AG arm, hazard ratio of 

0.52 (95% CI:  0.22, 1.23);

•  The primary safety endpoint of decreasing the rate of TE events in Stage 2 was also met with the rate of TE events reducing 
from 43 percent to 10 percent in the PAG arm and from 25 percent to 6 percent in the AG arm, following a protocol 
amendment that excluded patients at high risk of TE events and with the introduction of prophylaxis with low molecular 
weight heparin (enoxaparin) in Stage 2 of the study with the current 1mg/kg/day dose of enoxaparin prophylaxis given 
in both treatment arms of the study.

Study 202 is an ongoing study with an open database and therefore we continue to collect and receive data on both Stage 1 
and Stage 2 patients. When the database is considered complete and locked, an updated analysis and Final Study Report will be 
generated.

Study Halo 109-301:

In March 2015, we met with the FDA to discuss both the interim efficacy and safety data from Study 109-202, which included 
the potential risk profile including TE event rate. Based on the feedback from that meeting, we proceeded with a Phase 3 clinical 
study (Study 109-301) of PEGPH20 in patients with stage IV PDA, using a design allowing for potential marketing application 
based on either PFS or OS. The study will enroll patients whose tumors accumulate high levels of HA measured using the Ventana 
companion diagnostic test. The FDA provided feedback on the current companion diagnostic approach and confirmed that an 
approved IDE is required for the Phase 3 study.

The use of PFS as the basis for marketing approval will be subject to the overall benefit and risk associated with PEGPH20 

combined with gemcitabine and ABRAXANE therapy, including the:

•  Magnitude of the PFS treatment effect observed;
•  Toxicity profile; and 
Interim OS data.
• 

In June 2015, we received scientific advice/protocol assistance from the European Medicines Agency (EMA) regarding our 
Phase 3 study. The EMA agreed to the patient population, and the use of both PFS and OS as co-primary endpoints stating that 
OS is the preferred endpoint and that ultimate approval would require an overall positive benefit:risk balance.

In  March  2016,  we  dosed  the  first  patient  in  Study  109-301,  a  Phase  3  multicenter  randomized  clinical  trial  evaluating 
PEGPH20 as a first-line therapy for patients with stage IV PDA. The study will evaluate the effects on PFS and OS of PEGPH20 
with gemcitabine and ABRAXANE compared with gemcitabine and ABRAXANE alone in stage IV PDA patients at approximately 
200 sites in 20 countries located in North America, Europe, South America and Asia Pacific. By January 2017, we had initiated 
85% of the global study sites participating in the HALO 301 study.

SWOG Study S1313:

In October 2013, SWOG, a cancer research cooperative group of more than 4,000 researchers in over 500 institutions around 
the world, initiated a 144 patient Phase 1b/2 randomized clinical trial in some of their study centers, examining PEGPH20 in 
combination with modified FOLFIRINOX chemotherapy (mFOLFIRINOX) compared to mFOLFIRINOX treatment alone in 
patients with stage IV PDA (funded by the National Cancer Institute). This study was also placed on clinical hold temporarily at 
the time of the hold on Study 109-202. In September 2014, the FDA removed the clinical hold on patient enrollment and dosing 
of PEGPH20 in this SWOG cooperative study. The study has resumed under a revised protocol, and patient enrollment is continuing. 
The Phase 2 portion of the study, where up to 172 patients are planned to be enrolled, began in June 2015. As with Study 109-202, 
the occurrence of TE events will be closely monitored in enrolled patients, and the continuation of this study may be halted again 
in accordance with event rate rules established in the protocol, or for other safety reasons.

Clinical collaboration:

In October 2016, we announced that PEGPH20 will be included in a pancreatic cancer clinical trial initiative called Precision 
Promise, an initiative that aims to change the current treatment approach to pancreatic cancer by offering options to patients based 
on the molecular profile of their tumor. This is being accomplished through the Pancreatic Cancer Action Network leading a 
collaboration that brings together clinicians, researchers, and drug developers. Pancreatic Cancer Action Network has announced 
plans to begin enrolling patients at 12 initial consortium sites in Spring 2017.

Other indications outside of pancreatic cancer:

Study HALO 107-201, PRIMAL Study: 

In  December  2014,  we  initiated  a  Phase  1b/2  trial,  to  evaluate  PEGPH20  in  second  line  in  combination  with  docetaxel 
(Taxotere®) in non-small cell lung cancer patients. In August 2016, after assessing recruitment and the enrollment of increasingly 
later line patients, we discontinued the PRIMAL study.

Study HALO 107-101: 

In November 2015, we initiated a Phase 1b study exploring the combination of PEGPH20 and KEYTRUDA®, an immuno-
oncology agent in relapsed non-small cell lung cancer (NSCLC) and gastric cancer. In December 2016, we identified a dose of 
PEGPH20, namely 2.2 ug/kg, to move into the dose expansion phase of the study with KEYTRUDA in combination with PEGPH20.  
We are now enrolling both NSCLC and gastric cancer patients prospectively based on a patient being determined to be HA-High 
using the Ventana companion diagnostic test.  

Clinical collaborations:

In July 2015, we entered into a clinical collaboration agreement with Eisai Co., Ltd.. (Eisai) to evaluate Eisai's HALAVEN®  
(eribulin) with PEGPH20 in HER2-negative metastatic breast cancer. In July 2016, the first patient was dosed in a Phase 1b/2 
study for patients treated with up to two lines of prior therapy for HER2-negative HA-High metastatic breast cancer. Halozyme 
and Eisai are jointly sharing the costs to conduct this global study which remains in dose escalation. 

In November 2016, we entered into an agreement with Genentech, a member of the Roche Group, to collaborate on clinical 
studies evaluating up to eight different tumor types, beginning in 2017. The first study will be a Phase 1b/2 open-label, multi-arm 
randomized global study, led by Genentech to evaluate their cancer immunotherapy Tecentriq® (atezolizumab), an anti-PD-L1 
monoclonal antibody, in combination with PEGPH20 in up to six tumor types. Halozyme will supply PEGPH20  for the Genentech 
study, which will have an initial focus on gastrointestinal malignancies, including pancreatic and gastric cancers. The second study 
will  be  a  Phase  1b  open-label  randomized  study  led  by  Halozyme  to  assess  Tecentriq  in  combination  with  PEGPH20  and 
chemotherapy in advanced or metastatic biliary and gallbladder cancers. Genentech will supply Tecentriq  for the Halozyme study. 

Regulatory

The FDA has granted Fast Track designation for our program investigating PEGPH20 in combination with gemcitabine and 
nab-paclitaxel for the treatment of patients with stage IV PDA to demonstrate an improvement in OS. The Fast Track designation 
process was developed by the FDA to facilitate the development and expedite the review of drugs to treat serious or life-threatening 
diseases and address unmet medical needs.

The FDA has granted Orphan Drug designation for PEGPH20 for the treatment of pancreatic cancer. The FDA Office of 
Orphan Products Development’s mission is to advance the evaluation and development of products (drugs, biologics, devices, or 
medical foods) that demonstrate promise for the diagnosis and/or treatment of rare diseases or conditions. Similarly, the European 
Committee for Orphan Medicinal Products of the EMA designated PEGPH20 an orphan medicinal product for the treatment of 
pancreatic cancer.

In March 2015, we met with the FDA to discuss both the interim efficacy and safety data from Study 109-202 and to discuss 
the Phase 3 Study 109-301 as a potential registration study in stage IV PDA patients whose tumors are determined to have high 
levels of HA accumulation. In June 2015, we received scientific advice/protocol assistance from the EMA regarding our Phase 3 
study. In March 2016, our partner, Ventana, received approval for an IDE application from the FDA for our companion diagnostic 
test to enable patient selection in our Phase 3 Study 301 of PEGPH20 in HA-High patients.

Other Pipeline Assets 

PEG-ADA2: PEGylated adenosine deaminase 2, or PEG-ADA2, is an immune checkpoint inhibitor that targets adenosine, 
which may accumulate to high levels in the tumor microenvironment and has been linked to immunosuppression. We are currently 
in preclinical development with PEG-ADA2, with the next milestone expected to be final drug candidate selection to determine 
its suitability for continued evaluation as a targeted therapy for clinical development.

HTI-1511: HTI-1511 is a novel antibody-drug conjugate (ADC) targeting epidermal growth factor receptor (EGFR) to treat 
solid tumors, including those with drug-resistant mutations. We are in preclinical development with a drug candidate selected. 
Good laboratory practices (GLP) toxicity studies and chemistry, manufacturing and controls (CMC) development activities are 
planned as next steps in support of a potential investigational new drug (IND) filing.

ENHANZE Collaborations

Roche Collaboration

In December 2006, we and Roche entered into a collaboration and license agreement under which Roche obtained a worldwide, 
license to develop and commercialize product combinations of rHuPH20 and up to thirteen Roche target compounds (the Roche 
Collaboration). Roche initially had the exclusive right to apply rHuPH20 to three pre-defined Roche biologic targets with the 
option to develop and commercialize rHuPH20 with ten additional targets. Roche had the right to exercise this option to identify 
additional targets for ten years. As of the ten year anniversary of the Roche Collaboration in December 2016, Roche had elected 
a total of eight targets, two of which are exclusive. 

In September 2013, Roche launched a subcutaneous (SC) formulation of Herceptin (trastuzumab) (Herceptin SC) in Europe 
for the treatment of patients with HER2-positive breast cancer. This formulation utilizes our patented ENHANZE Technology and 
is administered in two to five minutes, compared to 30 to 90 minutes with the standard intravenous form. Roche received European 
marketing approval for Herceptin SC in August 2013. The European Commission’s approval was based on data from Roche’s 
Phase 3 HannaH study which showed that the subcutaneous formulation of Herceptin was associated with comparable efficacy 
(pathological complete response, pCR) to Herceptin administered intravenously in women with HER2-positive early breast cancer 
and resulted in non-inferior trastuzumab plasma levels. Overall, the safety profile in both arms of the HannaH study was consistent 
with that expected from standard treatment with Herceptin and chemotherapy in this setting. No new safety signals were identified. 
Breast cancer is the most common cancer among women worldwide. In HER2-positive breast cancer, increased quantities of the 
human epidermal growth factor receptor 2 (HER2) are present on the surface of the tumor cells. This is known as “HER2 positivity” 
and affects approximately 15% to 20% of women with breast cancer. HER2-positive cancer is reported to be a particularly aggressive 
form of breast cancer. Directed at the same target, Roche initiated a Phase 1 study of rHuPH20 with PERJETA® (pertuzumab) in 
patients with early breast cancer in March 2016. 

In June 2014, Roche launched MabThera SC in Europe for the treatment of patients with common forms of non-Hodgkin 
lymphoma (NHL). This formulation utilizes our patented ENHANZE Technology and is administered in approximately five minutes 
compared to the approximately 2.5 hour infusion time for intravenous MabThera. The European Commission approved MabThera 
SC in March 2014. The European Commission’s approval was based primarily on data from Roche’s Phase 3 pivotal clinical 
studies, which was published in The Lancet Oncology. NHL is a type of cancer that affects lymphocytes (white blood cells). 
Lymphomas are a cancer of the lymphatic system (composed of lymph vessels, lymph nodes and organs) which helps to keep the 
bodily fluid levels balanced and to defend the body against invasion by disease. Lymphoma develops when white blood cells 
(usually B-lymphocytes) in the lymph fluid become cancerous and begin to multiply and collect in the lymph nodes or lymphatic 
tissues such as the spleen. Some of these cells are released into the bloodstream and spread to other parts of the body, interfering 
with the body’s production of healthy blood cells. In May 2016, Roche announced that the EMA approved Mabthera SC to treat 
patients with chronic lymphocytic leukemia (CLL).

In November 2016, the FDA accepted Genentech’s (a member of the Roche Group) Biologic License Application (BLA) for 
a subcutaneous formulation of rituximab for CLL and NHL. This is a co-formulation with rHuPH20, which is approved and 
marketed under the MabThera SC brand in countries outside the U.S.

Baxalta Collaboration

In September 2007, we and Baxalta entered into a collaboration and license agreement under which Baxalta obtained a 
worldwide, exclusive license to develop and commercialize product combinations of rHuPH20 with GAMMAGARD LIQUID 
(HYQVIA) (the Baxalta Collaboration). GAMMAGARD LIQUID is a current Baxalta product that is indicated for the treatment 
of primary immunodeficiency disorders associated with defects in the immune system.

9

In May 2013, the European Commission granted Baxalta marketing authorization in all EU Member States for the use of 
HYQVIA  (solution  for  subcutaneous  use)  as  replacement  therapy  for  adult  patients  with  primary  and  secondary 
immunodeficiencies. Baxalta launched HYQVIA in the first EU country in July 2013 and has continued to launch in additional 
countries.

In October 2014, Baxalta announced the launch and first shipments of Baxalta’s HYQVIA product for treatment of adult 
patients with primary immunodeficiency in the U.S. HYQVIA was approved by the FDA in September 2014 and is the first 
subcutaneous  immune  globulin  (IG)  treatment  approved  for  adult  primary  immunodeficiency  patients  with  a  dosing  regimen 
requiring only one infusion up to once per month (every three to four weeks) and one injection site per infusion in most patients, 
to deliver a full therapeutic dose of IG. The majority of primary immunodeficiency patients today receive intravenous infusions 
in a doctor’s office or infusion center, and current subcutaneous IG treatments require weekly or bi-weekly treatment with multiple 
infusion sites per treatment. The FDA’s approval of HYQVIA was a significant milestone for us as it represented the first U.S. 
approved BLA which utilizes our rHuPH20 platform. 

In May 2016, Baxalta announced that HYQVIA received a marketing authorization from the European Commission for a 
pediatric indication, which is being launched in eight European countries to treat primary and certain secondary immunodeficiencies. 

Pfizer Collaboration

In December 2012, we and Pfizer entered into a collaboration and license agreement, under which Pfizer has the worldwide 
license to develop and commercialize products combining our rHuPH20 enzyme with Pfizer proprietary biologics directed to up 
to six targets in primary care and specialty care indications. Targets may be selected on an exclusive or non-exclusive basis. Pfizer 
has elected five targets on an exclusive basis. One of the targets is proprotein convertase subtilisin/kexin type 9 (PCSK9). Pfizer 
initiated dosing of a subcutaneous formulation of rHuPH20 and bococizumab, an investigational PCSK9 inhibitor, in a Phase 1 
trial in February 2016. In November 2016, Pfizer announced they discontinued their development program for bococizumab, 
including the development of the subcutaneous formulation of rHuPH20 with bococizumab. In December 2016, Pfizer returned 
PCSK9 as an elected target. In April 2016, Pfizer completed a Phase 1 study of rHuPH20 with rivipansel, directed to another target 
to  treat  vaso-occlusive  crisis  in  individuals  with  sickle  cell  disease,  demonstrating  feasibility  of  large  volume  subcutaneous 
administration with rHuPH20. In November 2016, Pfizer made a portfolio decision to discontinue development of rHuPH20 with 
rivipansel. Pfizer is currently in development of one program on the ENHANZE platform with an undisclosed target. 

Janssen Collaboration

In December 2014, we and Janssen entered into a collaboration and license agreement, under which Janssen has the worldwide 
license to develop and commercialize products combining our rHuPH20 enzyme with Janssen proprietary biologics directed to 
up to five targets. Targets may be selected on an exclusive basis. Janssen has elected CD38 as the first target on an exclusive basis. 
In November 2015, Janssen initiated dosing in a Phase 1b clinical trial evaluating subcutaneous delivery of daratumumab, directed 
at CD38, using ENHANZE Technology, in multiple myeloma patients. In December 2016, Janssen announced results of the trial, 
which supported continued development of daratumumab with rHuPH20. Janssen has said it plans to initiate a Phase 3 study of 
daratumumab combined with the ENHANZE technology.

AbbVie Collaboration

In June 2015, we and AbbVie entered into a collaboration and license agreement, under which AbbVie has the worldwide 
license to develop and commercialize products combining our rHuPH20 enzyme with AbbVie proprietary biologics directed to 
up to nine targets. Targets may be selected on an exclusive basis. AbbVie elected TNF alpha as the first target on an exclusive 
basis. In January 2016, AbbVie initiated dosing in a Phase 1 clinical trial evaluating if rHuPH20 with adalimumab (HUMIRA®) 
would allow for a reduced number of induction injections and deliver additional performance benefits. In November 2016, AbbVie 
discontinued this program following completion of the Phase 1 study in which the target results were not achieved.

Lilly Collaboration

In December 2015, we and Lilly entered into a collaboration and license agreement, under which Lilly has the worldwide 
license to develop and commercialize products combining our rHuPH20 enzyme with Lilly proprietary biologics directed to up 
to five targets. Targets may be selected on an exclusive basis. Lilly has elected two targets on an exclusive basis and one target on 
a semi-exclusive basis.

Patents and Proprietary Rights

Patents and other proprietary rights are essential to our business. Our success will depend in part on our ability to obtain 
patent protection for our inventions, to preserve our trade secrets and to operate without infringing the proprietary rights of third 
parties. Our strategy is to actively pursue patent protection in the U.S. and certain foreign jurisdictions for technology that we 
believe to be proprietary to us and that offers us a potential competitive advantage. Our patent portfolio includes 25 issued patents 
in the U.S., more than 285 issued patents in Europe and other countries in the world and more than 300 pending patent applications. 
In general, patents have a term of 20 years from the application filing date or earlier claimed priority date. Our issued patents will 
expire between 2022 and 2032. We have multiple patents and patent applications throughout the world pertaining to our recombinant 
human hyaluronidase and methods of use and manufacture, including an issued U.S. patent which expires in 2027 and an issued 
European  patent  which  expires  in  2024,  which  we  believe  cover  the  products  and  product  candidates  under  our  existing 
collaborations, Hylenex recombinant, PEGPH20 and our endocrinology product candidates. In addition, we have, under prosecution 
throughout the world, multiple patent applications that relate specifically to individual product candidates under development, the 
expiration of which can only be definitely determined upon maturation into our issued patents. We believe our patent filings 
represent a barrier to entry for potential competitors looking to utilize these hyaluronidases.

In addition to patents, we rely on unpatented trade secrets, proprietary know-how and continuing technological innovation. 
We seek protection of these trade secrets, proprietary know-how and innovation, in part, through confidentiality and proprietary 
information agreements. Our policy is to require our employees, directors, consultants, advisors, collaborators, outside scientific 
collaborators and sponsored researchers, other advisors and other individuals and entities to execute confidentiality agreements 
upon the start of employment, consulting or other contractual relationships with us. These agreements provide that all confidential 
information developed or made known to the individual or entity during the course of the relationship is to be kept confidential 
and not disclosed to third parties except in specific circumstances. In the case of employees and some other parties, the agreements 
provide that all inventions conceived by the individual will be our exclusive property. Despite the use of these agreements and our 
efforts to protect our intellectual property, there will always be a risk of unauthorized use or disclosure of information. Furthermore, 
our trade secrets may otherwise become known to, or be independently developed by, our competitors.

We also file trademark applications to protect the names of our products and product candidates. These applications may 
not mature to registration and may be challenged by third parties. We are pursuing trademark protection in a number of different 
countries around the world. There can be no assurances that our registered or unregistered trademarks or trade names will not 
infringe on rights of third parties or will be acceptable to regulatory agencies.

Research and Development Activities

Our research and development expenses consist primarily of costs associated with the development and manufacturing of 
our product candidates, compensation and other expenses for research and development personnel, supplies and materials, costs 
for consultants and related contract research, clinical trials, facility costs and amortization and depreciation. We charge all research 
and development expenses to operations as they are incurred. Our research and development activities are primarily focused on 
the development of our various product candidates.

11

Due to the uncertainty in obtaining the FDA and other regulatory approvals, our reliance on third parties and competitive 
pressures, we are unable to estimate with any certainty the additional costs we will incur in the continued development of our 
proprietary product candidates for commercialization. However, we expect our research and development expenses for PEGPH20 
to increase as our program advances into additional tumors and later stages of clinical development.

Manufacturing

We do not have our own manufacturing facility for our product and product candidates, or the capability to package our 

products. We have engaged third parties to manufacture bulk rHuPH20, PEGPH20 and Hylenex recombinant.

We have existing supply agreements with contract manufacturing organizations Avid Bioservices, Inc. (Avid) and Cook 
Pharmica LLC (Cook) to produce supplies of bulk rHuPH20. These manufacturers each produce bulk rHuPH20 under current 
Good Manufacturing Practices (cGMP) for clinical and commercial uses. Cook currently produces bulk rHuPH20 for use in Hylenex
recombinant,  product  candidates  and  collaboration  product  candidates.  Avid  currently  produces  bulk  rHuPH20  for  use  in 
collaboration products. We rely on their ability to successfully manufacture these batches according to product specifications. In 
addition, we are working to scale-up, validate and qualify a new facility operated by Avid as a manufacturer of bulk rHuPH20 for 
use in the products and product candidates under the Roche Collaboration. It is important for our business for Cook and Avid to 
(i) retain their status as cGMP-approved manufacturing facilities; (ii) successfully scale up bulk rHuPH20 production; and/or 
(iii) manufacture the bulk rHuPH20 required by us and our collaborators for use in our proprietary and collaboration products and 
product candidates. In addition to supply obligations, Avid and Cook will also provide support for data and information used in 
the chemistry, manufacturing and controls sections for FDA and other regulatory filings.

We have a commercial manufacturing and supply agreement with Patheon Manufacturing Services, LLC (Patheon) under 
which Patheon will provide the final fill and finishing steps in the production process of Hylenex recombinant. Under our commercial 
services agreement with Patheon, Patheon has agreed to fill and finish Hylenex recombinant product for us until December 31, 
2019, subject to further extensions in accordance with the terms of the agreement. In addition, we are scaling up our manufacturing 
of PEGPH20 with third party suppliers to support additional clinical trials, including the Phase 3 trial, and ultimately, if approved, 
potential commercial supply.

Sales, Marketing and Distribution

Hylenex Recombinant

Our commercial activities currently focus on Hylenex recombinant. We have a team of sales specialists that provide hospital 
and surgery center customers with the information about Hylenex recombinant and information needed to obtain formulary approval 
for, and support utilization of, Hylenex recombinant. Our commercial activities also include marketing and related services and 
commercial support services such as commercial operations, managed markets and commercial analytics. We also employ third-
party vendors, such as advertising agencies, market research firms and suppliers of marketing and other sales support related 
services to assist with our commercial activities.

We sell Hylenex recombinant in the U.S. to wholesale pharmaceutical distributors, who sell the product to hospitals and other 
end-user customers. We have engaged Integrated Commercialization Solutions (ICS), a division of AmerisourceBergen Specialty 
Group, a subsidiary of AmerisourceBergen, to act as our exclusive distributor for commercial shipment and distribution of Hylenex
recombinant to our customers in the United States. In addition to distribution services, ICS provides us with other key services 
related to logistics, warehousing, returns and inventory management, contract administration and chargebacks processing and 
accounts receivable management. In addition, we utilize third parties to perform various other services for us relating to regulatory 
monitoring, including call center management, adverse event reporting, safety database management and other product maintenance 
services.

Competition

The pharmaceutical industry is characterized by rapidly advancing technologies, intense competition and a strong emphasis 
on proprietary therapeutics. We face competition from a number of sources, some of which may target the same indications as our 
product  or  product  candidates,  including  large  pharmaceutical  companies,  smaller  pharmaceutical  companies,  biotechnology 
companies, academic institutions, government agencies and private and public research institutions, many of which have greater 
financial resources, drug development experience, sales and marketing capabilities, including larger, well established sales forces, 
manufacturing capabilities, experience in obtaining regulatory approvals for product candidates and other resources than us. We 
face competition not only in the commercialization of Hylenex recombinant, but also for the in-licensing or acquisition of additional 
product candidates, and the out-licensing of our ENHANZE Technology. In addition, our collaborators face competition in the 

12

commercialization of the product candidates for which the collaborators seek marketing approval from the FDA or other regulatory 
authorities.

Hylenex Recombinant

Hylenex recombinant is currently the only FDA approved recombinant human hyaluronidase on the market. The competitors 
for Hylenex recombinant include, but are not limited to, Valeant Pharmaceuticals International, Inc.’s product, Vitrase®, an ovine 
(ram) hyaluronidase, and Amphastar Pharmaceuticals, Inc.’s product, Amphadase®, a bovine (bull) hyaluronidase. In addition, 
some commercial pharmacies compound hyaluronidase preparations for institutions and physicians even though compounded 
preparations are not FDA approved products.

Government Regulations

The FDA and comparable regulatory agencies in foreign countries regulate the manufacture and sale of the pharmaceutical 
products that we have developed or currently are developing. The FDA has established guidelines and safety standards that are 
applicable to the laboratory and preclinical evaluation and clinical investigation of therapeutic products and stringent regulations 
that govern the manufacture and sale of these products. The process of obtaining regulatory approval for a new therapeutic product 
usually  requires  a  significant  amount  of  time  and  substantial  resources. The  steps  typically  required  before  a  product  can  be 
introduced for human use include:

• 

• 

animal pharmacology studies to obtain preliminary information on the safety and efficacy of a drug; or

laboratory and preclinical evaluation in vitro and in vivo including extensive toxicology studies.

The results of these laboratory and preclinical studies may be submitted to the FDA as part of an IND application. The 
sponsor of an IND application may commence human testing of the compound 30 days after submission of the IND, unless notified 
to the contrary by the FDA.

The clinical testing program for a new drug typically involves three phases:

• 

• 

• 

Phase 1 investigations are generally conducted in healthy subjects (in certain instances, Phase 1 studies that determine the 
maximum tolerated dose and initial safety of the product candidate are performed in patients with the disease);

Phase 2 studies are conducted in limited numbers of subjects with the disease or condition to be treated and are aimed at 
determining  the  most  effective  dose  and  schedule  of  administration,  evaluating  both  safety  and  whether  the  product 
demonstrates therapeutic effectiveness against the disease; and

Phase 3 studies involve large, well-controlled investigations in diseased subjects and are aimed at verifying the safety and 
effectiveness of the drug.

Data from all clinical studies, as well as all laboratory and preclinical studies and evidence of product quality, are typically 
submitted to the FDA in a new drug application (NDA). The results of the preclinical and clinical testing of a biologic product 
candidate are submitted to the FDA in the form of a BLA, for evaluation to determine whether the product candidate may be 
approved for commercial sale. In responding to a BLA or NDA, the FDA may grant marketing approval or request additional 
information. If additional information is requested we may provide such information or withdraw our application. Although the 
FDA’s requirements for clinical trials are well established and we believe that we have planned and conducted our clinical trials 
in accordance with applicable regulations and guidelines, these requirements may be subject to change. Accordingly, we could be 
required to conduct additional trials beyond what we had planned due to the FDA’s safety and/or efficacy concerns or due to 
differing interpretations of the meaning of our clinical data or a change in the therapeutic landscape. (See Part I, Item 1A, Risk 
Factors.)

The FDA’s Center for Drug Evaluation and Research must approve an NDA and the FDA’s Center for Biologics Evaluation 
and Research must approve a BLA for a drug before it may be marketed in the United States. If we begin to market our proposed 
products for commercial sale in the U.S., any manufacturing operations that may be established in or outside the U.S. will also be 
subject to rigorous regulation, including compliance with cGMP. We also may be subject to regulation under the Occupational 
Safety and Health Act, the Environmental Protection Act, the Toxic Substance Control Act, the Export Control Act and other 
present and future laws of general application. In addition, the handling, care and use of laboratory animals are subject to the 
Guidelines for the Humane Use and Care of Laboratory Animals published by the National Institutes of Health.

13

Regulatory obligations continue post-approval, and include the reporting of adverse events when a drug is utilized in the 
broader patient population. Promotion and marketing of drugs is also strictly regulated, with penalties imposed for violations of 
FDA regulations, the Lanham Act and other federal and state laws, including the federal anti-kickback statute.

We currently intend to continue to seek, directly or through our collaborators, approval to market our products and product 
candidates in foreign countries, which may have regulatory processes that differ materially from those of the FDA. We anticipate 
that we will rely upon independent consultants to seek and gain approvals to market our proposed products in foreign countries 
or may rely on other pharmaceutical or biotechnology companies to license our proposed products. We cannot guarantee that 
approvals to market any of our proposed products can be obtained in any country. Approval to market a product in any one foreign 
country does not necessarily indicate that approval can be obtained in other countries.

From time to time, legislation is drafted and introduced in Congress that could significantly change the statutory provisions 
governing the approval, manufacturing and marketing of drug products. In addition, FDA regulations and guidance are often 
revised or reinterpreted by the agency or reviewing courts in ways that may significantly affect our business and development of 
our product candidates and any products that we may commercialize. It is impossible to predict whether additional legislative 
changes will be enacted, or FDA regulations, guidance or interpretations changed, or what the impact of any such changes may 
be.

Segment Information

We  operate  our  business  as  one  segment,  which  includes  all  activities  related  to  the  research,  development  and 
commercialization of human enzymes and other drug candidates. This segment also includes revenues and expenses related to 
(i) research and development activities conducted under our collaboration agreements with third parties and (ii) product sales of 
Hylenex recombinant. The chief operating decision-maker reviews the operating results on an aggregate basis and manages the 
operations as a single operating segment. Our long-lived assets located in foreign countries had minimal book value as of December 
31, 2016 and 2015.

Item 1A.  Risk Factors

Risks Related To Our Business

We have generated only limited revenues from product sales to date; we have a history of net losses and negative cash flows, 
and we may never achieve or maintain profitability.

Relative to expenses incurred in our operations, we have generated only limited revenues from product sales, royalties, 
licensing fees, milestone payments, bulk rHuPH20 supply payments and research reimbursements to date, and we may never 
generate sufficient revenues from future product sales, licensing fees and milestone payments to offset expenses. Even if we 
ultimately do achieve significant revenues from product sales, royalties, licensing fees, research reimbursements, bulk rHuPH20 
supply payments and/or milestone payments, we expect to incur significant operating losses over the next few years. We have 
never been profitable, and we may never become profitable. Through December 31, 2016, we have incurred aggregate net losses 
of approximately $585.3 million.

If our product candidates do not receive and maintain regulatory approvals, or if approvals are not obtained in a timely 
manner, such failure or delay would substantially impair our ability to generate revenues.

Approval from the FDA or equivalent health authorities is necessary to manufacture and market pharmaceutical products in 
the U.S. and the other countries in which we anticipate doing business have similar requirements. The process for obtaining FDA 
and other regulatory approvals is extensive, time-consuming, risky and costly, and there is no guarantee that the FDA or other 
regulatory bodies will approve any applications that may be filed with respect to any of our product candidates, or that the timing 
of any such approval will be appropriate for the desired product launch schedule for a product candidate. We and our collaborators 
attempt  to  provide  guidance  as  to  the  timing  for  the  filing  and  acceptance  of  such  regulatory  approvals,  but  such  filings  and 
approvals may not occur when we or our collaborators expect, or at all. The FDA or other foreign regulatory agency may refuse 
or delay approval of our product candidates for failure to collect sufficient clinical or animal safety data and require us or our 
collaborators to conduct additional clinical or animal safety studies which may cause lengthy delays and increased costs to our 
programs. For example, the approval of Baxalta’s HYQVIA BLA in the U.S. was delayed until we and Baxalta provided additional 
preclinical  data  sufficient  to  address  concerns  regarding  non-neutralizing  antibodies  to  rHuPH20  that  were  detected  in  the 
registration trial. Although these antibodies have not been associated with any known adverse clinical effects, and the HYQVIA 
BLA was approved by the FDA in September 2014, we cannot assure you that they will not arise and have an adverse impact on 
future development of products which include rHuPH20, future sales of Hylenex recombinant, our ability to enter into collaborations, 
or be raised by the FDA or other health authorities in connection with testing or approval of products including rHuPH20.

We and our collaborators may not be successful in obtaining approvals for any additional potential products in a timely 
manner, or at all. Refer to the risk factor titled “Our proprietary and collaboration product candidates or companion diagnostic 
assays may not receive regulatory approvals or their development may be delayed for a variety of reasons, including delayed or 
unsuccessful clinical trials, regulatory requirements or safety concerns” for additional information relating to the approval of 
product candidates. 

Additionally,  even  with  respect  to  products  which  have  been  approved  for  commercialization,  in  order  to  continue  to 
manufacture and market pharmaceutical products, we or our collaborators must maintain our regulatory approvals. If we or any 
of our collaborators are unsuccessful in maintaining our regulatory approvals, our ability to generate revenues would be adversely 
affected.

We will likely need to raise additional capital in the future and there can be no assurance that we will be able to obtain such 
funds.

We will likely need to raise additional capital in the future to continue the development of our product candidates or for other 
current corporate purposes. Our current cash reserves and expected revenues during the next few years will not be sufficient for 
us to continue the development of our proprietary product candidates, to fund general operations and conduct our business at the 
level desired. In addition, if we engage in acquisitions of companies, products or technologies in order to execute our business 
strategy, we may need to raise additional capital. We may raise additional capital in the future through one or more financing 
vehicles that may be available to us including (i) the public offering of securities; (ii) new collaborative agreements; (iii) expansions 
or revisions to existing collaborative relationships; (iv) private financings; (v) other equity or debt financings; and/or (vi) monetizing 
assets.

In view of our stage of development, business prospects, the nature of our capital structure and general market conditions, 
if we are required to raise additional capital in the future, the additional financing may not be available on favorable terms, or at 
all. If additional capital is not available on favorable terms when needed, we will be required to raise capital on adverse terms or 
significantly reduce operating expenses through the restructuring of our operations or deferral of one or more product development 
programs. If we raise additional capital, a substantial number of additional shares may be issued, and these shares will dilute the 
ownership interest of our current investors.

Use of our product candidates or those of our collaborators could be associated with side effects or adverse events.

As with most pharmaceutical products, use of our product candidates or those of our collaborators could be associated with 
side effects or adverse events which can vary in severity (from minor reactions to death) and frequency (infrequent or prevalent). 
Side effects or adverse events associated with the use of our product candidates or those of our collaborators may be observed at 
any time, including in clinical trials or when a product is commercialized, and any such side effects or adverse events may negatively 
affect our or our collaborators’ ability to obtain or maintain regulatory approval or market our product candidates. Side effects 
such as toxicity or other safety issues associated with the use of our product candidates or those of our collaborators could require 
us or our collaborators to perform additional studies or halt development or commercialization of these product candidates or 
expose us to product liability lawsuits which will harm our business. We or our collaborators may be required by regulatory agencies 
to conduct additional animal or human studies regarding the safety and efficacy of our pharmaceutical product candidates which 
we have not planned or anticipated. Furthermore, there can be no assurance that we or our collaborators will resolve any issues 
related to any product related adverse events to the satisfaction of the FDA or any regulatory agency in a timely manner or ever, 
which could harm our business, prospects and financial condition. For example, in April 2014, a clinical hold was placed on patient 
enrollment and dosing of PEGPH20 in Study 202 as a result of a possible difference in the TE event rate that had been observed 
at that time in the trial between the group of patients treated with PEGPH20 versus the group of patients treated without PEGPH20. 
The clinical hold was lifted by the FDA in June 2014, and we have completed enrollment and continue to monitor ongoing patients 
who remain either on treatment or in follow-up on Study 202 under a revised clinical protocol. 

If our contract manufacturers are unable to manufacture and supply to us bulk rHuPH20 or other raw materials in the 
quantity  and  quality  required  by  us  or  our  collaborators  for  use  in  our  products  and  product  candidates,  our  product 
development and commercialization efforts could be delayed or stopped and our collaborations could be damaged.

We have existing supply agreements with contract manufacturing organizations Avid Bioservices, Inc. (Avid) and Cook 
Pharmica LLC (Cook) to produce bulk rHuPH20. These manufacturers each produce bulk rHuPH20 under cGMP for clinical 
uses. Cook currently produces bulk rHuPH20 for use in Hylenex recombinant, product candidates and collaboration product 
candidates. Avid currently produces bulk rHuPH20 for use in collaboration products. In addition to supply obligations, Avid and 
Cook will also provide support for the chemistry, manufacturing and controls sections for FDA and other regulatory filings. We 
rely on their ability to successfully manufacture these batches according to product specifications. If either Avid or Cook: (i) is 
unable to retain its status as an FDA approved manufacturing facility; (ii) is unable to otherwise successfully scale up bulk 
rHuPH20 production to meet corporate or regulatory authority quality standards; or (iii) fails to manufacture and supply bulk 
rHuPH20 in the quantity and quality required by us or our collaborators for use in our proprietary and collaboration products 
and product candidates for any other reason, our business will be adversely affected. In addition, a significant change in such 
parties’ or other third party manufacturers’ business or financial condition could adversely affect their abilities to fulfill their 
contractual obligations to us. We have not established, and may not be able to establish, favorable arrangements with additional 
bulk rHuPH20 manufacturers and suppliers of the ingredients necessary to manufacture bulk rHuPH20 should the existing 
manufacturers and suppliers become unavailable or in the event that our existing manufacturers and suppliers are unable to 
adequately perform their responsibilities. We have attempted to mitigate the impact of a potential supply interruption through 
the establishment of excess bulk rHuPH20 inventory where possible, but there can be no assurances that this safety stock will 
be maintained or that it will be sufficient to address any delays, interruptions or other problems experienced by Avid and/or 
Cook. Any delays, interruptions or other problems regarding the ability of Avid and/or Cook to supply bulk rHuPH20 or the 
ability of other third party manufacturers, to supply other raw materials or ingredients necessary to produce our products on a 
timely basis could: (i) cause the delay of clinical trials or otherwise delay or prevent the regulatory approval of proprietary or 
collaboration product candidates; (ii) delay or prevent the effective commercialization of proprietary or collaboration products; 
and/or (iii) cause us to breach contractual obligations to deliver bulk rHuPH20 to our collaborators. Such delays would likely 
damage our relationship with our collaborators, and they would have a material adverse effect on royalties and thus our business 
and financial condition.

16

If we or any party to a key collaboration agreement fail to perform material obligations under such agreement, or if a key 
collaboration agreement, is terminated for any reason, our business could significantly suffer.

We have entered into multiple collaboration agreements under which we may receive significant future payments in the form 
of milestone payments, target designation fees, maintenance fees and royalties. We are dependent on our collaborators to develop 
and commercialize product candidates subject to our collaborations in order for us to realize any financial benefits from these 
collaborations. Our collaborators may not devote the attention and resources to such efforts that we would ourselves, change their 
clinical development plans, promotional efforts or simultaneously develop and commercialize products in competition to those 
products we have licensed to them. Any of these actions could not be visible to us immediately and could negatively impact the 
benefits  and  revenue  we  receive  from  such  collaboration.  In  addition,  in  the  event  that  a  party  fails  to  perform  under  a  key 
collaboration agreement, or if a key collaboration agreement is terminated, the reduction in anticipated revenues could delay or 
suspend our product development activities for some of our product candidates, as well as our commercialization efforts for some 
or all of our products. Specifically, the termination of a key collaboration agreement by one of our collaborators could materially 
impact our ability to enter into additional collaboration agreements with new collaborators on favorable terms, if at all. In certain 
circumstances, the termination of a key collaboration agreement would require us to revise our corporate strategy going forward 
and reevaluate the applications and value of our technology.

Most of our current proprietary and collaboration products and product candidates rely on the rHuPH20 enzyme, and any 
adverse development regarding rHuPH20 could substantially impact multiple areas of our business, including current and 
potential collaborations, as well as proprietary programs.

rHuPH20 is a key technological component of ENHANZE Technology and our most advanced proprietary and collaboration 
products and product candidates, including the current and future products and product candidates under our Roche, Pfizer, Janssen, 
Baxalta, AbbVie and Lilly collaborations, our PEGPH20 program, and Hylenex recombinant. If there is an adverse development 
for rHuPH20 (e.g., an adverse regulatory determination relating to rHuPH20, if we are unable to obtain sufficient quantities of 
rHuPH20, if we are unable to obtain or maintain material proprietary rights to rHuPH20 or if we discover negative characteristics 
of rHuPH20), multiple areas of our business, including current and potential collaborations, as well as proprietary programs would 
be substantially impacted. For example, elevated anti-rHuPH20 antibody titers were detected in the registration trial for Baxalta’s 
HYQVIA product as well as in a former collaborator’s product in a Phase 2 clinical trial with rHuPH20, but have not been associated, 
in either case, with any adverse events. We monitor for antibodies to rHuPH20 in our collaboration and proprietary programs, and 
although we do not believe at this time that the incidence of non-neutralizing anti-rHuPH20 antibodies in either the HYQVIA 
program or the former collaborator’s program will have a significant impact on our other proprietary and other collaboration 
product candidates, there can be no assurance that there will not be other such occurrences in the foregoing programs or our other 
programs or that concerns regarding these antibodies will not also be raised by the FDA or other health authorities in the future, 
which could result in delays or discontinuations of our development or commercialization activities or deter entry into additional 
collaborations with third parties. 

We routinely evaluate, and may modify, our business strategy and our strategic focus to only a few fields or applications of 
our technology which may increase the risk for potential negative impact from adverse developments.

We routinely evaluate our business strategy, and may modify this strategy in the future in light of our assessment of unmet 
medical needs, growth potential, resource requirements, regulatory issues, competition, risks and other factors. As a result of these 
strategic evaluations, we may focus our resources and efforts on one or a few programs or fields and may suspend or reduce our 
efforts on other programs and fields. For example, in the third quarter of 2014, we decided to focus our resources on advancing 
PEGPH20 and expanding utilization of our ENHANZE platform. While we believe these are applications with the greatest potential 
value, we have reduced the diversification of our programs and increased our dependence on the success of the areas we are 
pursuing. By focusing on one or a few areas, we increase the potential impact on us if one of those programs or product candidates 
does not successfully complete clinical trials, achieve commercial acceptance or meet expectations regarding sales and revenue. 
Our decision to focus on one or a few programs may also reduce the value of programs that are no longer within our principal 
strategic focus, which could impair our ability to pursue collaborations or other strategic alternatives for those programs we are 
not pursuing.

17

Our proprietary and collaboration product candidates or companion diagnostic assays may not receive regulatory approvals 
or their development may be delayed for a variety of reasons, including delayed or unsuccessful clinical trials, regulatory 
requirements or safety concerns.

Clinical testing of pharmaceutical products is a long, expensive and uncertain process, and the failure or delay of a clinical 
trial can occur at any stage, including the patient enrollment stage. Even if initial results of preclinical and nonclinical studies or 
clinical trial results are promising, we or our collaborators may obtain different results in subsequent trials or studies that fail to 
show the desired levels of safety and efficacy, or we may not, or our collaborators may not, obtain applicable regulatory approval 
for a variety of other reasons. Preclinical, nonclinical, and clinical trials for any of our proprietary or collaboration product candidates 
or development of any collaboration companion diagnostic assays could be unsuccessful, which would delay or preclude regulatory 
approval and commercialization of the product candidates or companion diagnostic assays. In the U.S. and other jurisdictions, 
regulatory approval can be delayed, limited or not granted for many reasons, including, among others:

• 

• 

• 

• 

• 
• 

• 

• 

• 

• 

• 

• 

• 

clinical results may not meet prescribed endpoints for the studies or otherwise provide sufficient data to support the 
efficacy of our product candidates;
clinical and nonclinical test results may reveal side effects, adverse events or unexpected safety issues associated 
with the use of our product candidates; for example, in April 2014, a clinical hold was placed on patient enrollment 
and dosing of PEGPH20 in Study 202 as a result of a possible difference in the TE event rate that had been observed 
at that time in the trial between the group of patients treated with PEGPH20 versus the group of patients treated 
without PEGPH20. The clinical hold was lifted by the FDA in June 2014, and we have completed enrollment and 
continue to monitor ongoing patients who remain either on treatment or in follow-up on Study 202 under a revised 
clinical protocol;
completion of clinical trials may be delayed for a variety of reasons including the amount of time it may take to 
identify and enroll patients with high levels of HA in our target population, and the ability to procure drug supply 
required in clinical trial protocols; 
regulatory review may not find a product candidate safe or effective enough to merit either continued testing or final 
approval;
regulatory review may not find that the data from preclinical testing and clinical trials justifies approval;
regulatory authorities may require that we change our studies or conduct additional studies which may significantly 
delay or make continued pursuit of approval commercially unattractive; 
a regulatory agency may reject our trial data or disagree with our interpretations of either clinical trial data or applicable 
regulations;
a regulatory agency may approve only a narrow use of our product or may require additional safety monitoring and 
reporting through Risk Evaluation and Mitigation Strategies or conditions to assure safe use programs;
the cost of clinical trials required for product approval may be greater than what we originally anticipate, and we 
may decide to not pursue regulatory approval for such a product;
a regulatory agency may not approve our manufacturing processes or facilities, or the processes or facilities of our 
collaborators, our contract manufacturers or our raw material suppliers;
a regulatory agency may identify problems or other deficiencies in our existing manufacturing processes or facilities, 
or the existing processes or facilities of our collaborators, our contract manufacturers or our raw material suppliers; 
a regulatory agency may change its formal or informal approval requirements and policies, act contrary to previous 
guidance, adopt new regulations or raise new issues or concerns late in the approval process; or
a product candidate may be approved only for indications that are narrow or under conditions that place the product 
at a competitive disadvantage, which may limit the sales and marketing activities for such product candidate or 
otherwise adversely impact the commercial potential of a product.

If a proprietary or collaboration product candidate or companion diagnostic assay is not approved in a timely fashion or 
obtained on commercially viable terms, or if development of any product candidate or a companion diagnostic assay is terminated 
due to difficulties or delays encountered in the regulatory approval process, it could have a material adverse impact on our business, 
and we would become more dependent on the development of other proprietary or collaboration product candidates and/or our 
ability to successfully acquire other products and technologies. There can be no assurances that any proprietary or collaboration 
product candidate or companion diagnostic assay will receive regulatory approval in a timely manner, or at all. There can be no 
assurance that we will be able to gain clarity as to the FDA’s requirements or that the requirements may be satisfied in a commercially 
feasible way, in which case our ability to enter into collaborations with third parties or explore other strategic alternatives to exploit 
this opportunity will be limited or may not be possible.

18

We anticipate that certain proprietary and collaboration products will be marketed, and perhaps manufactured, in foreign 
countries. The process of obtaining regulatory approvals in foreign countries is subject to delay and failure for the reasons set forth 
above, as well as for reasons that vary from jurisdiction to jurisdiction. The approval process varies among countries and jurisdictions 
and can involve additional testing. The time required to obtain approval may differ from that required to obtain FDA approval. 
Foreign regulatory agencies may not provide approvals on a timely basis, if at all. Approval by the FDA does not ensure approval 
by regulatory authorities in other countries or jurisdictions, and approval by one foreign regulatory authority does not ensure 
approval by regulatory authorities in other foreign countries or jurisdictions or by the FDA.

Our third party collaborators are responsible for providing certain proprietary materials that are essential components of 
our collaboration products and product candidates, and any failure to supply these materials could delay the development 
and commercialization efforts for these collaboration products and product candidates and/or damage our collaborations.

Our development and commercialization collaborators are responsible for providing certain proprietary materials that are 
essential components of our collaboration products and product candidates. For example, Roche is responsible for producing the 
Herceptin and MabThera required for its subcutaneous products and Baxalta is responsible for producing the GAMMAGARD 
LIQUID for its product HYQVIA. If a collaborator, or any applicable third party service provider of a collaborator, encounters 
difficulties in the manufacture, storage, delivery, fill, finish or packaging of the collaboration product or product candidate or 
component of such product or product candidate, such difficulties could (i) cause the delay of clinical trials or otherwise delay or 
prevent the regulatory approval of collaboration product candidates; and/or (ii) delay or prevent the effective commercialization 
of collaboration products. Such delays could have a material adverse effect on our business and financial condition. 

We rely on third parties to manufacture, prepare, fill, finish and package our products and product candidates, and if such 
third parties should fail to perform, our commercialization and development efforts for our products and product candidates 
could be delayed or stopped.

We rely on third parties to manufacture, prepare, fill, finish, package, store and ship our products and product candidates on 
our behalf. If we are unable to locate third parties to perform these functions on terms that are acceptable to us, or if the third 
parties we identify fail to perform their obligations, the progress of clinical trials could be delayed or even suspended and the 
commercialization of approved product candidates could be delayed or prevented. In addition, we are scaling up our manufacturing 
of PEGPH20 with third party suppliers to support additional clinical trials, including the Phase 3 trial, and ultimately, if approved, 
potential commercial supply. If our contract manufacturers are unable to successfully manufacture and supply PEGPH20, the 
progress of our clinical trials could be delayed or halted for a period of time.

If we are unable to sufficiently develop our sales, marketing and distribution capabilities or enter into successful agreements 
with third parties to perform these functions, we will not be able to fully commercialize our products.

We may not be successful in marketing and promoting our approved product, Hylenex recombinant, or any other products 
we develop or acquire in the future. Our sales, marketing and distribution capabilities are very limited. In order to commercialize 
any  products  successfully,  we  must  internally  develop  substantial  sales,  marketing  and  distribution  capabilities  or  establish 
collaborations or other arrangements with third parties to perform these services. We do not have extensive experience in these 
areas, and we may not be able to establish adequate in-house sales, marketing and distribution capabilities or engage and effectively 
manage relationships with third parties to perform any or all of such services. To the extent that we enter into co-promotion or 
other licensing arrangements, our product revenues are likely to be lower than if we directly marketed and sold our products, and 
any revenues we receive will depend upon the efforts of third parties, whose efforts may not meet our expectations or be successful. 
These third parties would be largely responsible for the speed and scope of sales and marketing efforts, and may not dedicate the 
resources necessary to maximize product opportunities. Our ability to cause these third parties to increase the speed and scope of 
their efforts may also be limited. In addition, sales and marketing efforts could be negatively impacted by the delay or failure to 
obtain additional supportive clinical trial data for our products. In some cases, third party collaborators are responsible for conducting 
these additional clinical trials, and our ability to increase the efforts and resources allocated to these trials may be limited.

If we or our collaborators fail to comply with regulatory requirements applicable to promotion, sale and manufacturing of 
approved products, regulatory agencies may take action against us or them, which could significantly harm our business.

Any  approved  products,  along  with  the  manufacturing  processes,  post-approval  clinical  data,  labeling,  advertising  and 
promotional activities for these products, are subject to continual requirements and review by the FDA, state and foreign regulatory 
bodies. Regulatory authorities subject a marketed product, its manufacturer and the manufacturing facilities to continual review 
and periodic inspections. We, our collaborators and our respective contractors, suppliers and vendors, will be subject to ongoing 
regulatory  requirements,  including  complying  with  regulations  and  laws  regarding  advertising,  promotion  and  sales  of  drug 

19

products,  required  submissions  of  safety  and  other  post-market  information  and  reports,  registration  requirements,  cGMP 
regulations (including requirements relating to quality control and quality assurance, as well as the corresponding maintenance of 
records  and  documentation),  and  the  requirements  regarding  the  distribution  of  samples  to  physicians  and  recordkeeping 
requirements. Regulatory agencies may change existing requirements or adopt new requirements or policies. We, our collaborators 
and our respective contractors, suppliers and vendors, may be slow to adapt or may not be able to adapt to these changes or new 
requirements.

In  particular,  regulatory  requirements  applicable  to  pharmaceutical  products  make  the  substitution  of  suppliers  and 
manufacturers costly and time consuming. We have minimal internal manufacturing capabilities and are, and expect to be in the 
future, entirely dependent on contract manufacturers and suppliers for the manufacture of our products and for their active and 
other  ingredients.  The  disqualification  of  these  manufacturers  and  suppliers  through  their  failure  to  comply  with  regulatory 
requirements could negatively impact our business because the delays and costs in obtaining and qualifying alternate suppliers (if 
such alternative suppliers are available, which we cannot assure) could delay clinical trials or otherwise inhibit our ability to bring 
approved products to market, which would have a material adverse effect on our business and financial condition. Likewise, if 
we, our collaborators and our respective contractors, suppliers and vendors involved in sales and promotion of our products do 
not comply with applicable laws and regulations, for example off-label or false or misleading promotion, this could materially 
harm our business and financial condition.

Failure to comply with regulatory requirements may result in any of the following:

restrictions on our products or manufacturing processes;

• 
•  warning letters;
•  withdrawal of the products from the market;
• 
• 
• 
• 
• 
• 
• 
• 
• 

voluntary or mandatory recall;
fines;
suspension or withdrawal of regulatory approvals;
suspension or termination of any of our ongoing clinical trials;
refusal to permit the import or export of our products;
refusal to approve pending applications or supplements to approved applications that we submit;
product seizure; 
injunctions; or
imposition of civil or criminal penalties. 

We currently have significant debt and failure by us to fulfill our obligations under the applicable loan agreements may 
cause the repayment obligations to accelerate.

In December 2015, our subsidiaries, Halozyme, Inc. (Halozyme) and Halozyme Royalty LLC (Halozyme Royalty) entered 
into a credit agreement (the Credit Agreement) with BioPharma Credit Investments IV Sub, LP and Athyrium Opportunities II 
Acquisition LP (the Royalty-backed Lenders) pursuant to which we borrowed $150 million through Halozyme Royalty (the Royalty-
backed Loan). The Royalty-backed Loan will be repaid primarily from a specified percentage of the royalty payments we receive 
under our collaboration agreements with Roche and Baxalta (the Royalty Payments). 

The obligations of Halozyme Royalty under the Credit Agreement to repay the Royalty-backed Loan may be accelerated 

upon the occurrence of certain events of default under the Credit Agreement, including but not limited to:

• 

• 

• 

• 

• 

• 

if any payment of principal is not made within three days of when such payment is due and payable or otherwise 
made in accordance with the terms of the Credit Agreement;
if any representations or warranties made in the Credit Agreement or any other transaction document proves to be 
incorrect or misleading in any material respect when made;
if there occurs a default in the performance of affirmative and negative covenants set forth in the Credit 
Agreement or any other transaction document;
the failure by either Baxalta or Roche to pay material amounts owed under our collaboration agreements because 
of an actual breach or default by us under the collaboration agreements;
the voluntary or involuntary commencement of bankruptcy proceedings by either Halozyme or Halozyme Royalty 
and other insolvency related defaults;
any materially adverse effect on the binding nature of any of the transaction documents or the collaboration 
agreements with Baxalta and Roche; or

•  Halozyme ceases to own, of record and beneficially, 100% of the equity interests in Halozyme Royalty.

20

The Credit Agreement also contains covenants applicable to Halozyme and Halozyme Royalty, including certain visitation, 
information and audits rights granted to the collateral agent and the lenders and restrictions on the conduct of business, including 
continued compliance with the Baxalta and Roche collaboration agreements and specified affirmative actions regarding the escrow 
account established to facilitate payment of Royalty Payments to the Royalty-backed Lenders or other specified parties. The Credit 
Agreement  also  contains  covenants  solely  applicable  to  Halozyme  Royalty,  including  restrictions  on  incurring  indebtedness, 
creating or granting liens, making acquisitions and making specified restricted payments. These covenants could make it more 
difficult for us to execute our business strategy.

In connection with the Royalty-backed Loan, Halozyme Royalty granted a first priority lien and security interest (subject 
only to permitted liens) in all of its assets and all real, intangible and personal property, including all of its right, title and interest 
in and to the Royalty Payments. 

In June 2016, we entered into a Loan and Security Agreement (the New Loan Agreement) with Oxford Finance LLC (Oxford) 
and Silicon Valley Bank (SVB) (collectively, the Lenders), providing a senior secured loan facility of up to an aggregate principal 
amount of $70 million, comprising a $55.0 million draw in June 2016 and an additional $15.0 million tranche, which we have the 
option to draw during the second quarter of 2017. The initial proceeds were partially used to pay the outstanding principal and 
final payment owed on our previous loan agreement with the Lenders. The remaining proceeds, including any drawdown of the 
additional $15.0 million, are to be used for working capital and general business requirements. The New Loan Agreement is secured 
by substantially all of the assets of the Company and its subsidiary, Halozyme, Inc., except that the collateral does not include any 
equity interests in Halozyme, Inc., any intellectual property (including all licensing, collaboration and similar agreements relating 
thereto), and certain other excluded assets. The New Loan Agreement contains customary representations, warranties and covenants 
by us, which covenants limit our ability to convey, sell, lease, transfer, assign or otherwise dispose of certain of our assets; engage 
in any business other than the businesses currently engaged in by us or reasonably related thereto; liquidate or dissolve; make 
certain management changes; undergo certain change of control events; create, incur, assume, or be liable with respect to certain 
indebtedness;  grant  certain  liens;  pay  dividends  and  make  certain  other  restricted  payments;  make  certain  investments;  make 
payments on any subordinated debt; and enter into transactions with any of our affiliates outside of the ordinary course of business 
or permit our subsidiaries to do the same. In addition, subject to certain exceptions, we are required to maintain with SVB our 
primary deposit accounts, securities accounts and commodities, and to do the same for our domestic subsidiary. Complying with 
these covenants may make it more difficult for us to successfully execute our business strategy. 

The New Loan Agreement also contains customary indemnification obligations and customary events of default, including, 
among other things, our failure to fulfill certain of our obligations under the New Loan Agreement and the occurrence of a material 
adverse change which is defined as a material adverse change in our business, operations or condition (financial or otherwise), a 
material impairment of the prospect of repayment of any portion of the loan, or a material impairment in the perfection or priority 
of the Lender’s lien in the collateral or in the value of such collateral. 

Our ability to make payments on our debt will depend on our future operating performance and ability to generate cash and 
may also depend on our ability to obtain additional debt or equity financing. We will need to use cash to pay principal and interest 
on our debt, thereby reducing the funds available to fund our research and development programs, strategic initiatives and working 
capital requirements. If we are unable to generate sufficient cash to service our debt obligation, an event of default may occur. In 
the event of default by us under the Credit Agreement or the New Loan Agreement, the lenders would be entitled to exercise their 
remedies thereunder, including the right to accelerate the debt, upon which we may be required to repay all amounts then outstanding 
under the Credit Agreement or the New Loan Agreement which could harm our financial condition.

If proprietary or collaboration product candidates are approved for marketing but do not gain market acceptance, our business 
may suffer and we may not be able to fund future operations.

Assuming that our proprietary or collaboration product candidates obtain the necessary regulatory approvals for commercial 
sale, a number of factors may affect the market acceptance of these existing product candidates or any other products which are 
developed or acquired in the future, including, among others:

• 
• 

•

• 

the price of products relative to other therapies for the same or similar treatments;
the perception by patients, physicians and other members of the health care community of the effectiveness and safety 
of these products for their prescribed treatments relative to other therapies for the same or similar treatments;
our ability to fund our sales and marketing efforts and the ability and willingness of our collaborators to fund sales 
and marketing efforts;
the degree to which the use of these products is restricted by the approved product label;
the effectiveness of our sales and marketing efforts and the effectiveness of the sales and marketing efforts of our 
collaborators;

• 
• 

the introduction of generic competitors; and
the extent to which reimbursement for our products and related treatments will be available from third party payors 
including government insurance programs (Medicare and Medicaid) and private insurers.

If these products do not gain market acceptance, we may not be able to fund future operations, including the development 
or acquisition of new product candidates and/or our sales and marketing efforts for our approved products, which would cause our 
business to suffer.

In  addition,  our  proprietary  and  collaboration  product  candidates  will  be  restricted  to  the  labels  approved  by  FDA  and 
applicable regulatory bodies, and these restrictions may limit the marketing and promotion of the ultimate products. If the approved 
labels are restrictive, the sales and marketing efforts for these products may be negatively affected.

Developing and marketing pharmaceutical products for human use involves significant product liability risks for which we 
currently have limited insurance coverage.

The testing, marketing and sale of pharmaceutical products involves the risk of product liability claims by consumers and 
other  third  parties. Although  we  maintain  product  liability  insurance  coverage,  product  liability  claims  can  be  high  in  the 
pharmaceutical industry, and our insurance may not sufficiently cover our actual liabilities. If product liability claims were to be 
made against us, it is possible that the liabilities may exceed the limits of our insurance policy, or our insurance carriers may deny, 
or attempt to deny, coverage in certain instances. If a lawsuit against us is successful, then the lack or insufficiency of insurance 
coverage  could  materially  and  adversely  affect  our  business  and  financial  condition.  Furthermore,  various  distributors  of 
pharmaceutical products require minimum product liability insurance coverage before purchase or acceptance of products for 
distribution. Failure to satisfy these insurance requirements could impede our ability to achieve broad distribution of our proposed 
products, and higher insurance requirements could impose additional costs on us. In addition, since many of our collaboration 
product  candidates  include  the  pharmaceutical  products  of  a  third  party,  we  run  the  risk  that  problems  with  the  third  party 
pharmaceutical product will give rise to liability claims against us.

Our inability to attract, hire and retain key management and scientific personnel could negatively affect our business.

Our success depends on the performance of key management and scientific employees with relevant experience. For example, 
in  order  to  pursue  our  current  business  strategy,  we  will  need  to  recruit  and  retain  personnel  experienced  in  oncology  drug 
development which is a highly competitive market for talent. We depend substantially on our ability to hire, train, motivate and 
retain high quality personnel, especially our scientists and management team. Particularly in view of the small number of employees 
on our staff to cover our numerous programs and key functions, if we are unable to retain existing personnel or identify or hire 
additional personnel, we may not be able to research, develop, commercialize or market our products and product candidates as 
expected or on a timely basis and we may not be able to adequately support current and future alliances with strategic collaborators. 
Our use of domestic and international third-party contractors, consultants and staffing agencies also subjects us to potential co-
employment liability claims.

Furthermore, if we were to lose key management personnel, we would likely lose some portion of our institutional knowledge 
and  technical  know-how,  potentially  causing  a  substantial  delay  in  one  or  more  of  our  development  programs  until  adequate 
replacement personnel could be hired and trained. We currently have a severance policy applicable to all employees and a change 
in control policy applicable to senior executives.

We do not have key man life insurance policies on the lives of any of our employees.

Our operations might be interrupted by the occurrence of a natural disaster or other catastrophic event.

Our  operations,  including  laboratories,  offices  and  other  research  facilities,  are  located  in  four  buildings  in  San  Diego, 
California. In addition, we have a satellite office in South San Francisco, California. We depend on our facilities and on our 
collaborators, contractors and vendors for the continued operation of our business. Natural disasters or other catastrophic events, 
interruptions in the supply of natural resources, political and governmental changes, wildfires and other fires, floods, explosions, 
actions of animal rights activists, earthquakes and civil unrest could disrupt our operations or those of our collaborators, contractors 
and vendors. Even though we believe we carry commercially reasonable business interruption and liability insurance, and our 
contractors may carry liability insurance that protect us in certain events, we may suffer losses as a result of business interruptions 
that exceed the coverage available under our and our contractors’ insurance policies or for which we or our contractors do not have 
coverage. Any natural disaster or catastrophic event could have a significant negative impact on our operations and financial results. 
Moreover, any such event could delay our research and development programs.

22

If we or our collaborators do not achieve projected development, clinical, regulatory or sales goals in the timeframes we 
publicly announce or otherwise expect, the commercialization of our products and the development of our product candidates 
may be delayed and, as a result, our stock price may decline, and we may face lawsuits relating to such declines.

From time to time, we or our collaborators may publicly articulate the estimated timing for the accomplishment of certain 
scientific, clinical, regulatory and other product development goals. The accomplishment of any goal is typically based on numerous 
assumptions, and the achievement of a particular goal may be delayed for any number of reasons both within and outside of our 
control. If scientific, regulatory, strategic or other factors cause us to not meet a goal, regardless of whether that goal has been 
publicly articulated or not, our stock price may decline rapidly. For example, the announcement in April 2014 of the temporary 
halting of our Phase 2 clinical trial for PEGPH20 caused a rapid decline in our stock price. Stock price declines may also trigger 
direct or derivative shareholder lawsuits. As with any litigation proceeding, the eventual outcome of any legal action is difficult 
to predict. If any such lawsuits occur, we will incur expenses in connection with the defense of these lawsuits, and we may have 
to pay substantial damages or settlement costs in connection with any resolution thereof. Although we have insurance coverage 
against which we may claim recovery against some of these expenses and costs, the amount of coverage may not be adequate to 
cover the full amount or certain expenses and costs may be outside the scope of the policies we maintain. In the event of an adverse 
outcome or outcomes, our business could be materially harmed from depletion of cash resources, negative impact on our reputation, 
or restrictions or changes to our governance or other processes that may result from any final disposition of the lawsuit. Moreover, 
responding to and defending pending litigation significantly diverts management’s attention from our operations.

In addition, the consistent failure to meet publicly announced milestones may erode the credibility of our management team 

with respect to future milestone estimates. 

Future acquisitions could disrupt our business and harm our financial condition.

In order to augment our product pipeline or otherwise strengthen our business, we may decide to acquire additional businesses, 
products and technologies. As we have limited experience in evaluating and completing acquisitions, our ability as an organization 
to make such acquisitions is unproven. Acquisitions could require significant capital infusions and could involve many risks, 
including, but not limited to, the following:

•  we  may  have  to  issue  convertible  debt  or  equity  securities  to  complete  an  acquisition,  which  would  dilute  our 

• 

stockholders and could adversely affect the market price of our common stock;
an acquisition may negatively impact our results of operations because it may require us to amortize or write down 
amounts related to goodwill and other intangible assets, or incur or assume substantial debt or liabilities, or it may 
cause adverse tax consequences, substantial depreciation or deferred compensation charges;

•  we  may  encounter  difficulties  in  assimilating  and  integrating  the  business,  products,  technologies,  personnel  or 

• 

• 

operations of companies that we acquire;
certain acquisitions may impact our relationship with existing or potential collaborators who are competitive with 
the acquired business, products or technologies;
acquisitions may require significant capital infusions and the acquired businesses, products or technologies may not 
generate sufficient value to justify acquisition costs;

•  we may take on liabilities from the acquired company such as debt, legal liabilities or business risk which could be 

significant;
an acquisition may disrupt our ongoing business, divert resources, increase our expenses and distract our 
management;
acquisitions may involve the entry into a geographic or business market in which we have little or no prior experience; 
and
key personnel of an acquired company may decide not to work for us.

• 

• 

• 

If any of these risks occurred, it could adversely affect our business, financial condition and operating results. There is no 
assurance that we will be able to identify or consummate any future acquisitions on acceptable terms, or at all. If we do pursue 
any acquisitions, it is possible that we may not realize the anticipated benefits from such acquisitions or that the market will not 
view such acquisitions positively.

Security breaches may disrupt our operations and harm our operating results.

The wrongful use, theft, deliberate sabotage or any other type of security breach with respect to any of our information 
technology storage and access systems could result in the disruption of our ability to use such systems or disclosure or dissemination 
of our proprietary and confidential information that is electronically stored, including research or clinical data, resulting in a 
material adverse impact on our business, operating results and financial condition. Our security and data recovery measures may 

23

not be adequate to protect against computer viruses, break-ins, and similar disruptions from unauthorized tampering with our 
electronic storage systems. Furthermore, any physical break-in or trespass of our facilities could result in the misappropriation, 
theft, sabotage or any other type of security breach with respect to our proprietary and confidential information, including research 
or clinical data or damage to our research and development equipment and assets. Such adverse effects could be material and 
irrevocable to our business, operating results and financial condition.

Risks Related To Ownership of Our Common Stock

Our stock price is subject to significant volatility.

We participate in a highly dynamic industry which often results in significant volatility in the market price of common stock 
irrespective  of  company  performance. The  high  and  low  sales  prices  of  our  common  stock  during  the  twelve  months  ended 
December 31, 2016 were $17.51 and $6.96, respectively. We expect our stock price to continue to be subject to significant volatility 
and, in addition to the other risks and uncertainties described elsewhere in this Annual Report on Form 10-K and all other risks 
and uncertainties that are either not known to us at this time or which we deem to be immaterial, any of the following factors may 
lead to a significant drop in our stock price:

• 
• 

• 

• 
• 

• 
• 
• 
• 

• 
• 

• 
• 
• 
• 

• 

• 
• 

• 
• 
• 

the presence of competitive products to those being developed by us;
failure  (actual  or  perceived)  of  our  collaborators  to  devote  attention  or  resources  to  the  development  or 
commercialization of product candidates licensed to such collaborator;
a dispute regarding our failure, or the failure of one of our third party collaborators, to comply with the terms of a 
collaboration agreement; 
the termination, for any reason, of any of our collaboration agreements;
the sale of common stock by any significant stockholder, including, but not limited to, direct or indirect sales by 
members of management or our Board of Directors;
the resignation, or other departure, of members of management or our Board of Directors;
general negative conditions in the healthcare industry;
general negative conditions in the financial markets;
the cost associated with obtaining regulatory approval for any of our proprietary or collaboration product 
candidates;
the failure, for any reason, to secure or defend our intellectual property position;
for those products that are not yet approved for commercial sale, the failure or delay of applicable regulatory bodies 
to approve such products;
identification of safety or tolerability issues;
failure of clinical trials to meet efficacy endpoints;
suspensions or delays in the conduct of clinical trials or securing of regulatory approvals;
adverse regulatory action with respect to our and our collaborators’ products and product candidates such as clinical 
holds, imposition of onerous requirements for approval or product recalls;
our  failure,  or  the  failure  of  our  third  party  collaborators,  to  successfully  commercialize  products  approved  by 
applicable regulatory bodies such as the FDA;
our failure, or the failure of our third party collaborators, to generate product revenues anticipated by investors;
disruptions  in  our  clinical  or  commercial  supply  chains,  including  disruptions  caused  by  problems  with  a  bulk 
rHuPH20 contract manufacturer or a fill and finish manufacturer for any product or product candidate; 
the sale of additional debt and/or equity securities by us;
our failure to obtain financing on acceptable terms or at all; or
a restructuring of our operations.

Future transactions where we raise capital may negatively affect our stock price.

We are currently a “Well-Known Seasoned Issuer” and may file automatic shelf registration statements at any time with the 
SEC. Sales of substantial amounts of shares of our common stock or other securities under our shelf registration statements could 
lower the market price of our common stock and impair our ability to raise capital through the sale of equity securities. In the 
future, we may issue additional options, warrants or other derivative securities convertible into our common stock.

24

Anti-takeover provisions in our charter documents and Delaware law may make an acquisition of us more difficult.

Anti-takeover provisions in our charter documents and Delaware law may make an acquisition of us more difficult. First, 
our board of directors is classified into three classes of directors. Under Delaware law, directors of a corporation with a classified 
board may be removed only for cause unless the corporation’s certificate of incorporation provides otherwise. Our amended and 
restated certificate of incorporation, as amended, does not provide otherwise. In addition, our bylaws limit who may call special 
meetings of stockholders, permitting only stockholders holding at least 50% of our outstanding shares to call a special meeting of 
stockholders. Our amended and restated certificate of incorporation, as amended, does not include a provision for cumulative 
voting for directors. Under cumulative voting, a minority stockholder holding a sufficient percentage of a class of shares may be 
able to ensure the election of one or more directors. Finally, our bylaws establish procedures, including advance notice procedures, 
with regard to the nomination of candidates for election as directors and stockholder proposals.

These provisions may discourage potential takeover attempts, discourage bids for our common stock at a premium over 
market price or adversely affect the market price of, and the voting and other rights of the holders of, our common stock. These 
provisions  could  also  discourage  proxy  contests  and  make  it  more  difficult  for  stockholders  to  elect  directors  other  than  the 
candidates nominated by our board of directors.

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware 

General Corporation Law, which may prohibit large stockholders from consummating a merger with, or acquisition of, us.

These provisions may deter an acquisition of us that might otherwise be attractive to stockholders.

Risks Related to Our Industry

Our  products  must  receive  regulatory  approval  before  they  can  be  sold,  and  compliance  with  the  extensive  government 
regulations is expensive and time consuming and may result in the delay or cancellation of product sales, introductions or 
modifications.

Extensive industry regulation has had, and will continue to have, a significant impact on our business. All pharmaceutical 
companies, including ours, are subject to extensive, complex, costly and evolving regulation by the health regulatory agencies 
including  the  FDA  (and  with  respect  to  controlled  drug  substances,  the  U.S.  Drug  Enforcement Administration  (DEA))  and 
equivalent foreign regulatory agencies and state and local/regional government agencies. The Federal Food, Drug and Cosmetic 
Act,  the  Controlled  Substances Act  and  other  domestic  and  foreign  statutes  and  regulations  govern  or  influence  the  testing, 
manufacturing, packaging, labeling, storing, recordkeeping, safety, approval, advertising, promotion, sale and distribution of our 
products. We are dependent on receiving FDA and other governmental approvals, including regulatory approvals in jurisdictions 
outside the United States, prior to manufacturing, marketing and shipping our products. Consequently, there is always a risk that 
the FDA or other applicable governmental authorities, including those outside the United States, will not approve our products or 
may impose onerous, costly and time-consuming requirements such as additional clinical or animal testing. Regulatory authorities 
may require that we change our studies or conduct additional studies, which may significantly delay or make continued pursuit of 
approval commercially unattractive. For example, the approval of Baxalta’s HYQVIA BLA was delayed by the FDA until we and 
Baxalta provided additional preclinical data sufficient to address concerns regarding non-neutralizing antibodies to rHuPH20 that 
were detected in the registration trial. Although these antibodies have not been associated with any known adverse clinical effects, 
and the HYQVIA BLA was approved by the FDA in September 2014, the FDA or other foreign regulatory agency may, at any 
time, halt our and our collaborators’ development and commercialization activities due to safety concerns. In addition, even if our 
products are approved, regulatory agencies may also take post-approval action limiting or revoking our ability to sell our products. 
Any of these regulatory actions may adversely affect the economic benefit we may derive from our products and therefore harm 
our financial condition.

Under certain of these regulations, we and our contract suppliers and manufacturers are subject to periodic inspection of our 
or their respective facilities, procedures and operations and/or the testing of products by the FDA, the DEA and other authorities, 
which conduct periodic inspections to confirm that we and our contract suppliers and manufacturers are in compliance with all 
applicable regulations. The FDA also conducts pre-approval and post-approval reviews and plant inspections to determine whether 
our systems, or our contract suppliers’ and manufacturers’ processes, are in compliance with cGMP and other FDA regulations. 
If we, or our contract supplier, fail these inspections, we may not be able to commercialize our product in a timely manner without 
incurring significant additional costs, or at all.

In  addition,  the  FDA  imposes  a  number  of  complex  regulatory  requirements  on  entities  that  advertise  and  promote 
pharmaceuticals including, but not limited to, standards and regulations for direct-to-consumer advertising, off-label promotion, 
industry-sponsored scientific and educational activities, and promotional activities involving the internet.

25

We may be subject, directly or indirectly, to various broad federal and state healthcare laws. If we are unable to comply, or 
have not fully complied, with such laws, we could face civil, criminal and administrative penalties, damages, monetary fines, 
disgorgement,  possible  exclusion  from  participation  in  Medicare,  Medicaid  and  other  federal  healthcare  programs, 
contractual damages, reputational harm, diminished profits and future earnings and curtailment or restructuring of our 
operations, any of which could adversely affect our ability to operate.

Our business operations and activities may be directly, or indirectly, subject to various broad federal and state healthcare 
laws, including without limitation, anti-kickback laws, the Foreign Corrupt Practices Act, false claims laws, civil monetary penalty 
laws, data privacy and security laws, tracing and tracking laws, as well as transparency laws regarding payments or other items 
of value provided to healthcare providers. These laws may restrict or prohibit a wide range of business activities, including, but 
not  limited  to,  research,  manufacturing,  distribution,  pricing,  discounting,  marketing  and  promotion  and  other  business 
arrangements. These laws may impact, among other things, our current activities with principal investigators and research subjects, 
as well as sales, marketing and education programs. Many states have similar healthcare fraud and abuse laws, some of which 
may be broader in scope and may not be limited to items or services for which payment is made by a government health care 
program.

Efforts to ensure that our business arrangements will comply with applicable healthcare laws may involve substantial costs. 
While we have adopted a healthcare corporate compliance program, it is possible that governmental and enforcement authorities 
will conclude that our business practices may not comply with current or future statutes, regulations or case law interpreting 
applicable fraud and abuse or other healthcare laws. If our operations or activities are found to be in violation of any of the laws 
described above or any other governmental regulations that apply to us, we may be subject to, without limitation, civil, criminal 
and administrative penalties, damages, monetary fines, disgorgement, possible exclusion from participation in Medicare, Medicaid 
and  other  federal  healthcare  programs,  contractual  damages,  reputational  harm,  diminished  profits  and  future  earnings  and 
curtailment or restructuring of our operations, any of which could adversely affect our ability to operate.

In addition, any sales of products outside the U.S. will also likely subject us to foreign equivalents of the healthcare laws 

mentioned above, among other foreign laws.

We may be required to initiate or defend against legal proceedings related to intellectual property rights, which may result 
in substantial expense, delay and/or cessation of the development and commercialization of our products.

We primarily rely on patents to protect our intellectual property rights. The strength of this protection, however, is uncertain. 

For example, it is not certain that:

•  we will be able to obtain patent protection for our products and technologies;
• 

the scope of any of our issued patents will be sufficient to provide commercially significant exclusivity for our 
products and technologies;
others will not independently develop similar or alternative technologies or duplicate our technologies and obtain 
patent protection before we do; and
any of our issued patents, or patent pending applications that result in issued patents, will be held valid, enforceable 
and infringed in the event the patents are asserted against others.

• 

• 

We currently own or license several patents and also have pending patent applications applicable to rHuPH20 and other 
proprietary materials. There can be no assurance that our existing patents, or any patents issued to us as a result of our pending 
patent applications, will provide a basis for commercially viable products, will provide us with any competitive advantages, or 
will not face third party challenges or be the subject of further proceedings limiting their scope or enforceability. Any weaknesses 
or limitations in our patent portfolio could have a material adverse effect on our business and financial condition. In addition, if 
any of our pending patent applications do not result in issued patents, or result in issued patents with narrow or limited claims, 
this could result in us having no or limited protection against generic or biosimilar competition against our product candidates 
which would have a material adverse effect on our business and financial condition.

We may become involved in interference proceedings in the U.S. Patent and Trademark Office, or other proceedings in other 
jurisdictions, to determine the priority, validity or enforceability of our patents. In addition, costly litigation could be necessary to 
protect our patent position.

We also rely on trademarks to protect the names of our products (e.g. Hylenex recombinant). We may not be able to obtain 
trademark protection for any proposed product names we select. In addition, product names for pharmaceutical products must be 
approved  by  health  regulatory  authorities  such  as  the  FDA  in  addition  to  meeting  the  legal  standards  required  for  trademark 
protection and product names we propose may not be timely approved by regulatory agencies which may delay product launch. 

26

In addition, our trademarks may be challenged by others. If we enforce our trademarks against third parties, such enforcement 
proceedings may be expensive.

We also rely on trade secrets, unpatented proprietary know-how and continuing technological innovation that we seek to 
protect with confidentiality agreements with employees, consultants and others with whom we discuss our business. Disputes may 
arise concerning the ownership of intellectual property or the applicability or enforceability of these agreements, and we might 
not be able to resolve these disputes in our favor.

In  addition  to  protecting  our  own  intellectual  property  rights,  third  parties  may  assert  patent,  trademark  or  copyright 
infringement or other intellectual property claims against us. If we become involved in any intellectual property litigation, we may 
be required to pay substantial damages, including but not limited to treble damages, attorneys’ fees and costs, for past infringement 
if it is ultimately determined that our products infringe a third party’s intellectual property rights. Even if infringement claims 
against us are without merit, defending a lawsuit takes significant time, may be expensive and may divert management’s attention 
from other business concerns. Further, we may be stopped from developing, manufacturing or selling our products until we obtain 
a license from the owner of the relevant technology or other intellectual property rights. If such a license is available at all, it may 
require us to pay substantial royalties or other fees.

Patent protection for protein-based therapeutic products and other biotechnology inventions is subject to a great deal of 
uncertainty, and if patent laws or the interpretation of patent laws change, our competitors may be able to develop and 
commercialize products based on our discoveries.

Patent protection for protein-based therapeutic products is highly uncertain and involves complex legal and factual questions. 
In recent years, there have been significant changes in patent law, including the legal standards that govern the scope of protein 
and  biotechnology  patents.  Standards  for  patentability  of  full-length  and  partial  genes,  and  their  corresponding  proteins,  are 
changing. Recent court decisions have made it more difficult to obtain patents, by making it more difficult to satisfy the patentable 
subject matter requirement and the requirement of non-obviousness, have decreased the availability of injunctions against infringers, 
and have increased the likelihood of challenging the validity of a patent through a declaratory judgment action. Taken together, 
these decisions could make it more difficult and costly for us to obtain, license and enforce our patents. In addition, the Leahy-
Smith America Invents Act (HR 1249) was signed into law in September 2011, which among other changes to the U.S. patent 
laws, changes patent priority from “first to invent” to “first to file,” implements a post-grant opposition system for patents and 
provides for a prior user defense to infringement. These judicial and legislative changes have introduced significant uncertainty 
in the patent law landscape and may potentially negatively impact our ability to procure, maintain and enforce patents to provide 
exclusivity for our products.

There  also  have  been,  and  continue  to  be,  policy  discussions  concerning  the  scope  of  patent  protection  awarded  to 
biotechnology inventions. Social and political opposition to biotechnology patents may lead to narrower patent protection within 
the biotechnology industry. Social and political opposition to patents on genes and proteins and recent court decisions concerning 
patentability of isolated genes may lead to narrower patent protection, or narrower claim interpretation, for isolated genes, their 
corresponding proteins and inventions related to their use, formulation and manufacture. Patent protection relating to biotechnology 
products is also subject to a great deal of uncertainty outside the U.S., and patent laws are evolving and undergoing revision in 
many countries. Changes in, or different interpretations of, patent laws worldwide may result in our inability to obtain or enforce 
patents, and may allow others to use our discoveries to develop and commercialize competitive products, which would impair our 
business.

If third party reimbursement and customer contracts are not available, our products may not be accepted in the market.

Our ability to earn sufficient returns on our products will depend in part on the extent to which reimbursement for our products 
and related treatments will be available from government health administration authorities, private health insurers, managed care 
organizations and other healthcare providers.

Third-party payors are increasingly attempting to limit both the coverage and the level of reimbursement of new drug products 
to contain costs. Consequently, significant uncertainty exists as to the reimbursement status of newly approved healthcare products. 
Third party payors may not establish adequate levels of reimbursement for the products that we commercialize, which could limit 
their market acceptance and result in a material adverse effect on our revenues and financial condition.

Customer contracts, such as with group purchasing organizations and hospital formularies, will often not offer contract or 
formulary status without either the lowest price or substantial proven clinical differentiation. If our products are compared to 
animal-derived hyaluronidases by these entities, it is possible that neither of these conditions will be met, which could limit market 
acceptance and result in a material adverse effect on our revenues and financial condition.

27

The rising cost of healthcare and related pharmaceutical product pricing has led to cost containment pressures that could 
cause us to sell our products at lower prices, resulting in less revenue to us.

Any of the proprietary or collaboration products that have been, or in the future are, approved by the FDA may be purchased 
or  reimbursed  by  state  and  federal  government  authorities,  private  health  insurers  and  other  organizations,  such  as  health 
maintenance organizations and managed care organizations. Such third party payors increasingly challenge pharmaceutical product 
pricing. The trend toward managed healthcare in the U.S., the growth of such organizations, and various legislative proposals and 
enactments to reform healthcare and government insurance programs, including the Medicare Prescription Drug Modernization 
Act of 2003, could significantly influence the manner in which pharmaceutical products are prescribed and purchased, resulting 
in lower prices and/or a reduction in demand. Such cost containment measures and healthcare reforms could adversely affect our 
ability to sell our products.

In March 2010, the U.S. adopted the Patient Protection and Affordable Care Act, as amended by the Health Care and Education 
Reconciliation Act (the PPACA). This law substantially changes the way healthcare is financed by both governmental and private 
insurers, and significantly impacts the pharmaceutical industry. The PPACA contains a number of provisions that are expected to 
impact our business and operations, in some cases in ways we cannot currently predict. Changes that may affect our business 
include those governing enrollment in federal healthcare programs, reimbursement changes, fraud and abuse and enforcement. 
These changes will impact existing government healthcare programs and will result in the development of new programs, including 
Medicare payment for performance initiatives and improvements to the physician quality reporting system and feedback program.

Additional provisions of the PPACA may negatively affect our revenues in the future. For example, the PPACA imposes a 
non-deductible excise tax on pharmaceutical manufacturers or importers that sell branded prescription drugs to U.S. government 
programs that we believe will impact our revenues from our products. In addition, as part of the PPACA’s provisions closing a 
funding gap that currently exists in the Medicare Part D prescription drug program, we will also be required to provide a 50% 
discount on branded prescription drugs dispensed to beneficiaries under this prescription drug program. Recently, Congress and 
the new administration have proposed and taken various steps to revise, or delay implementation of, various aspects of the Heathcare 
Reform Act. We expect that the PPACA, as it may be amended, and other healthcare reform measures that may be adopted in the 
future could have a material adverse effect on our industry generally and on our ability to maintain or increase our product sales 
or successfully commercialize our product candidates and could limit or eliminate our future spending on development projects.

Furthermore, individual states have become increasingly aggressive in passing legislation and implementing regulations 
designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions 
on certain product access, importation from other countries and bulk purchasing. Legally mandated price controls on payment 
amounts by third party payors or other restrictions could negatively and materially impact our revenues and financial condition. 
We anticipate that we will encounter similar regulatory and legislative issues in most other countries outside the U.S.

We face intense competition and rapid technological change that could result in the development of products by others that 
are superior to our proprietary and collaboration products under development.

Our proprietary and collaboration products have numerous competitors in the U.S. and abroad including, among others, 
major  pharmaceutical  and  specialized  biotechnology  firms,  universities  and  other  research  institutions  that  have  developed 
competing products. The competitors for Hylenex recombinant include, but are not limited to, Valeant Pharmaceuticals International, 
Inc.’s  FDA-approved  product,  Vitrase®,  an  ovine  (ram)  hyaluronidase,  and  Amphastar  Pharmaceuticals,  Inc.’s  product, 
Amphadase®,  a  bovine  (bull)  hyaluronidase.  For  our  PEGPH20  product  candidate,  such  competitors  may  include  major 
pharmaceutical and specialized biotechnology firms. These competitors may develop technologies and products that are more 
effective, safer, or less costly than our current or future proprietary and collaboration product candidates or that could render our 
technologies and product candidates obsolete or noncompetitive. Many of these competitors have substantially more resources 
and  product  development,  manufacturing  and  marketing  experience  and  capabilities  than  we  do.  In  addition,  many  of  our 
competitors have significantly greater experience than we do in undertaking preclinical testing and clinical trials of pharmaceutical 
product candidates and obtaining FDA and other regulatory approvals of products and therapies for use in healthcare.

Item 2.  Properties

Our administrative offices and research facilities are currently located in San Diego, California. We lease an aggregate of 
approximately 76,000 square feet of office and research space for a monthly rent expense of approximately $145,000, net of costs 
and property taxes associated with the operation and maintenance of the subleased facilities. In addition, we have a satellite office 
in South San Francisco, California, where we lease approximately 10,000 square feet of office space for a monthly rent expense 
of approximately $26,000. We believe the current space is adequate for our immediate needs.

Item 3.  Legal Proceedings

From time to time, we may be involved in disputes, including litigation, relating to claims arising out of operations in the 
normal course of our business. Any of these claims could subject us to costly legal expenses and, while we generally believe that 
we have adequate insurance to cover many different types of liabilities, our insurance carriers may deny coverage or our policy 
limits may be inadequate to fully satisfy any damage awards or settlements. If this were to happen, the payment of any such awards 
could have a material adverse effect on our consolidated results of operations and financial position. Additionally, any such claims, 
whether or not successful, could damage our reputation and business. We currently are not a party to any legal proceedings, the 
adverse outcome of which, in management’s opinion, individually or in the aggregate, would have a material adverse effect on 
our consolidated results of operations or financial position.

Dividends

We have never declared or paid any dividends on our common stock. We currently intend to retain available cash for funding 
operations; therefore, we do not expect to pay any dividends on our common stock in the foreseeable future. In addition, the 
provisions of our borrowing arrangements limit, among other things, our ability to pay dividends and make certain other payments. 
Any future determination to pay dividends on our common stock will be at the discretion of our board of directors and will depend 
upon,  among  other  factors,  our  results  of  operations,  financial  condition,  capital  requirements,  contract  restrictions,  business 
prospects and other factors our board of directors may deem relevant.

 Management’s Discussion and Analysis of Financial Condition and Results of Operation

In addition to historical information, the following discussion contains forward-looking statements that are subject to risks 
and uncertainties. Actual results may differ substantially from those referred to herein due to a number of factors, including but 
not limited to risks described in the Part I, Item 1A, Risks Factors, and elsewhere in this Annual Report. References to “Notes” 
are Notes included in our Notes to Consolidated Financial Statements. 

Overview

Halozyme Therapeutics,  Inc.  is  a  biotechnology  company  focused  on  developing  and  commercializing  novel  oncology 
therapies. Our proprietary enzymes are used to facilitate the delivery of injected drugs and fluids, potentially enhancing the efficacy 
and the convenience of other drugs or can be used to alter tissue structures for potential clinical benefit. We exploit our technology 
and expertise using a two pillar strategy that we believe enables us to manage risk and cost by: (1) developing our own proprietary 
products in therapeutic areas with significant unmet medical needs, with a focus on oncology, and (2) licensing our technology to 
biopharmaceutical companies to collaboratively develop products that combine our technology with the collaborators’ proprietary 
compounds.

The majority of our approved product and product candidates are based on rHuPH20, our patented recombinant human 
hyaluronidase enzyme. Our proprietary development pipeline consists primarily of pre-clinical and clinical stage product candidates 
in oncology. Our lead oncology program is PEGPH20 (PEGylated recombinant human hyaluronidase), a molecular entity we are 
developing in combination with currently approved cancer therapies as a candidate for the systemic treatment of tumors that 
accumulate HA. We have demonstrated that when HA accumulates in a tumor, it can cause higher pressure in the tumor, reducing 
blood flow into the tumor and with that, reduced access of cancer therapies to the tumor. Through our efforts and efforts of our 
partners  and  collaborators,  we  are  currently  in  Phase  2  and  Phase  3  clinical  testing  for  PEGPH20  with ABRAXANE® (nab-
paclitaxel) and gemcitabine in stage IV pancreatic ductal adenocarcinoma (PDA) (Studies 109-202 and 109-301), in Phase 1b 
clinical testing for PEGPH20 with KEYTRUDA® (pembrolizumab) in non-small cell lung cancer and gastric cancer (Study 107-101) 
and in Phase 1b/2 clinical testing for PEGPH20 with HALAVEN® (eribulin) in patients treated with up to two lines of prior therapy 
for HER2-negative metastatic breast cancer.

We refer to the application of rHuPH20 to facilitate the delivery of other drugs or fluids as our ENHANZE™ Technology. 
We license the ENHANZE Technology to form collaborations with biopharmaceutical companies that develop or market drugs 
requiring or benefiting from injection via the subcutaneous route of administration. We currently have ENHANZE collaborations 
with F. Hoffmann-La Roche, Ltd. and Hoffmann-La Roche, Inc. (Roche), Baxalta US Inc. and Baxalta GmbH (Baxalta Incorporated 
was acquired by Shire plc in June 2016) (Baxalta), Pfizer Inc. (Pfizer), Janssen Biotech, Inc. (Janssen), AbbVie, Inc. (AbbVie), 
and Eli Lilly and Company (Lilly). We receive royalties from two of these collaborations, including royalties from sales of one 
product approved in both the United States and outside the United States from the Baxalta collaboration and from sales of two 
products approved for marketing outside the United States from the Roche collaboration. Future potential revenues from the sales 
and/or royalties of our approved products, product candidates, and ENHANZE collaborations will depend on the ability of Halozyme 
and  our  collaborators  to  develop,  manufacture,  secure  and  maintain  regulatory  approvals  for  approved  products  and  product 
candidates and commercialize product candidates.

Our 2016 and recent key accomplishments and events are as follows:

Clinical trials

• 

• 

• 

In January 2017, we announced topline results from the combined analysis of Stage 1 and Stage 2, and Stage 2 alone, of 
the Halo 109-202 study, based on a December 2016 data cutoff. Among the findings, the overall study population showed 
a  statistically  significant  increase  in  progression-free  survival  (PFS)  in  the  84  total  HA-High  patients  treated  with 
PEGPH20  plus  ABRAXANE  and  gemcitabine  when  compared  to  HA-High  patients  receiving  ABRAXANE  and 
gemcitabine alone. Stage 2 of the study, which completed enrollment in February 2016, showed a 91 percent improvement 
in median PFS for HA-High patients in the PEGPH20 arm, 8.6 months compared to 4.5 months in the control arm, and 
achieved its primary endpoint to evaluate and demonstrate a reduction in the rate of TE events in the PEGPH20 arm. 

In December 2016, we identified a dose of PEGPH20, namely 2.2 ug/kg, to move into the dose expansion phase of Study 
107-101, the study with KEYTRUDA in combination with PEGPH20. We are now enrolling both NSCLC and gastric 
cancer patients prospectively based on a patient being determined to be HA-High. 

In July 2016, we initiated a phase 1b/2 study with our partner, Eisai, Inc. (Eisai) exploring the combination of PEGPH20 
and eribulin in patients treated with up to two lines of prior therapy for HER2-negative HA-High metastatic breast cancer.

In March 2016, we dosed the first patient in the Phase 3 study of PEGPH20 (Halozyme Study 301) in previously untreated 
stage IV PDA HA-High patients. 

In March 2016, our partner, Ventana Medical Systems, Inc. (Ventana), received approval for an investigational device 
exemption (IDE) with the U.S. Food and Drug Administration (FDA) for the companion diagnostic test we co-developed 
to prospectively identify patients with high levels of HA.

ENHANZE collaborations 

In December 2016, Janssen announced results of the Phase 1b clinical trial, which supported continued development of 
daratumumab with rHuPH20. Janssen has said it plans to initiate a Phase 3 study.

In  November  2016,  Pfizer  discontinue  development  of  rHuPH20  with  rivipansel  and  with  bocoizumab,  and AbbVie 
discontinued development of rHuPH20 with HUMIRA. 

In November 2016, the FDA accepted Genentech’s BLA for a subcutaneous formulation of rituximab for CLL and NHL. 
This is a co-formulation with rHuPH20, which is approved and marketed under the MabThera SC brand in countries 
outside the U.S.

In May 2016, Roche announced that the European Medicines Agency approved MabThera SC to treat patients with 
chronic lymphocytic leukemia, demonstrating the expansion of our ENHANZE Technology into a new indication.

In May 2016, Baxalta announced that HYQVIA received a marketing authorization from the European Commission for 
a  pediatric  indication,  which  is  being  launched  in  eight  European  countries  to  treat  primary  and  certain  secondary 
immunodeficiencies.

In March 2016, Lilly and Pfizer each nominated a new target to be studied with ENHANZE Technology, triggering $9.5 
million  in  milestone  payments.  In  February  2016,  Pfizer  dosed  the  first  patient  in  a  Phase  1  clinical  trial  evaluating 
subcutaneous delivery of bococizumab with ENHANZE Technology, triggering a $1.0 million milestone payment. 

Clinical collaborations 

In November 2016, we entered into an agreement with Genentech, a member of the Roche Group, to collaborate on 
clinical studies evaluating up to eight different tumor types, beginning in 2017. The first study will be a Phase 1b/2 open-
label,  multi-arm,  randomized  global  study,  led  by  Genentech  to  evaluate  their  cancer  immunotherapy  Tecentriq® 
(atezolizumab), an anti-PD-L1 monoclonal antibody, in combination with PEGPH20 in up to six tumor types. Halozyme 
will supply drug only for the Genentech study. This study will have an initial focus on gastrointestinal malignancies, 
including pancreatic and gastric cancers. The second study will be a Phase 1b open-label randomized study led by Halozyme 
to assess Tecentriq in combination with PEGPH20 and chemotherapy in advanced or metastatic biliary and gallbladder 
cancers. 

In October 2016, we announced that PEGPH20 will be included in a pancreatic cancer clinical trial initiative called 
Precision Promise, an initiative that aims to change the current treatment approach to pancreatic cancer by offering options 
to patients based on the molecular profile of their tumor. This is being accomplished through the Pancreatic Cancer Action 
Network  leading  a  collaboration  that  brings  together  clinicians,  researchers,  and  drug  developers.  Pancreatic  Cancer 
Action Network has announced plans to begin enrolling patients at 12 initial consortium sites in Spring 2017.

Financing 

In June 2016, we entered into a new agreement with Oxford Finance LLC and Silicon Valley Bank to borrow $55.0 
million, which replaces our previous agreement and provides Halozyme the option to borrow an additional $15.0 million 
in 2017.

In January 2016, through our wholly-owned subsidiary, Halozyme Royalty, we received a $150.0 million loan secured 
by future royalties received from our collaborations with Roche and Baxalta.

Product sales, net increased in 2016 compared to 2015 due to an increase in the sales of bulk rHuPH20 to Baxalta and 
Roche. Product sales, net increased in 2015 compared to 2014 due to an increase in the sales of bulk rHuPH20 to Baxalta and an 
increase in sales of Hylenex. We expect that product sales of bulk rHuPH20 will fluctuate in future periods based on the needs of 
our collaborators and we may have periods of flat or declining revenue as our collaborators manage their inventories of bulk 
rHuPH20. We expect that future product sales of Hylenex will be flat or experience modest growth. 

Royalties – Royalty revenue was $51.0 million in 2016 compared to $31.0 million in 2015 and $9.4 million in 2014. The 
increases relate to increased sales of Herceptin SC and MabThera SC by Roche and increased sales of HYQVIA by Baxalta. We 
recognize royalties on sales of the collaboration products by the collaborators in the quarter following the quarter in which the 
corresponding sales occurred. In general, we expect royalty revenue to increase in future periods reflecting expected increases in 
sales of collaboration products, although we may have periods with flat or declining royalty revenue as sales of products under 
collaborations vary.

In 2016, we recognized $8.0 million in license fee revenue in connection with the Lilly Collaboration and $6.0 million in 
license fee revenue in connection with the AbbVie Collaboration related to target nominations. In 2015, we recognized $25.0 
million in license fee revenue in connection with the Lilly Collaboration and $23.0 million in license fee revenue in connection 
with  the AbbVie  Collaboration  related  to  upfront  payments.  In  2014,  we  recognized  $15.0  million  in  license  fee  revenue  in 
connection with the Janssen Collaboration upfront payment. These revenues vary from period to period based on our ENHANZE 
collaboration activity. We expect the non-reimbursement revenues under our collaborative agreements to continue to fluctuate in 
future periods based on our collaborators’ abilities to meet various clinical and regulatory milestones set forth in such agreements 
and our abilities to obtain new collaborative agreements. 

Revenue from reimbursements for research and development services increased in 2016 compared to 2015 mainly due to 
an increase in services provided to Roche related to work associated with bringing on-line a second contract manufacturing facility. 
The validation of the new facility is scheduled to end in 2017 and therefore we expect to see a decrease in research and development 
services to Roche in 2017. Revenue from reimbursements for research and development services decreased in 2015 compared to 
2014 mainly due to a decrease in reimbursements for manufacturing services to support the launches by Roche and Baxalta, 
compared to the same period in 2014. Research and development services rendered by us on behalf of our collaborators are at the 
request of the collaborators; therefore, the amount of future revenues related to reimbursable research and development services 
is uncertain. 

Cost of Product Sales — Cost of product sales increased in 2016 compared to 2015 by $4.0 million, or 14%, due to a $5.8 
million increase in cost of product sales of bulk rHuPH20 sold to collaboration partners partially offset by a $1.8 million decrease 
in Hylenex recombinant cost of product sales, due to a decrease in manufacturing costs. Cost of product sales increased in 2015
compared to 2014 by $6.5 million, or 29%, primarily due to the increased product sales of bulk rHuPH20 for HYQVIA. 

Research and Development — Research and development expenses consist of external costs, salaries and benefits and 
allocation of facilities and other overhead expenses related to research manufacturing, clinical trials, preclinical and regulatory 
activities. Research and development expenses incurred for the years ended December 31, 2016, 2015 and 2014 were as follows

Research and development expenses relating to our PEGPH20 program in 2016 increased by 43%, compared to 2015 primarily 
due  to  increased  clinical  trial  activities  in  Study  109-301,  Study  107-101  and  the  Eisai  Clinical  Collaboration.  Research  and 
development expenses relating to our PEGPH20 program in 2015 increased by 117%, compared to 2014 primarily due to increased 
clinical trial activities in Study 109-202. We expect these expenses to increase in future periods due to expected increases in our 
PEGPH20 development activities. Research and development expenses relating to our ENHANZE collaborations and our rHuPH20 
platform in 2016 increased by 189% compared to 2015, primarily due to a $17.0 million increase in manufacturing expenses related 
to Roche. The increase in Roche manufacturing expenses was primarily due to work associated with bringing on-line a second 
contract manufacturing facility. As we plan to complete validation of the new manufacturing facility in 2017, we expect these 
expenses to decrease. Research and development expenses related to other programs in 2016 increased by 74% compared to 2015 
primarily due to expenses incurred in our preclinical product programs. Research and development expenses related to other 
programs in 2015 decreased by 78% compared to 2014, primarily relating to the discontinuation of our ultrafast insulin program 
in 2015. 

Selling, General and Administrative — Selling, general and administrative (SG&A) expenses increased in 2016 compared 
to 2015 by $5.8 million, or 15%, and increased in 2015 compared to 2014 by $4.1 million, or 11%, primarily due to increases in 
compensation expense from higher average headcount. We expect SG&A expenses to increase moderately in future periods as our 
operations expand. 

35

 
Interest Expense — Interest expense included interest expense and amortization of the debt discount related to the long-
term debt. Interest expense increased by $14.8 million in 2016 as compared to 2015, primarily due to interest expense incurred 
on the Royalty-backed Loan we received in January 2016. Interest expense decreased by $0.4 million in 2015 as compared to 
2014.

Income Tax Expense — Income tax expense of $1.2 million in 2016 comprised U.S. federal alternative minimum tax. For 
the year ended December 31, 2016, we generated taxable income in the U.S., which was partially offset by utilizing net operating 
losses carried forward from earlier years. No income tax expense was recognized during the years ended December 31, 2015 and 
2014.  During  the  fourth  quarter  of  2016,  we  established  a  new  Swiss  subsidiary,  Halozyme  Switzerland  GmbH  (Halozyme 
Switzerland). Halozyme Switzerland is party to a tax ruling providing that the total Swiss income tax rate will not exceed 10% 
through December 2026. 

Liquidity and Capital Resources

Our principal sources of liquidity are our existing cash, cash equivalents and available-for-sale marketable securities. As of 
December 31, 2016, we had cash, cash equivalents and marketable securities of approximately $205.0 million. We will continue 
to have significant cash requirements to support product development activities. The amount and timing of cash requirements will 
depend on the progress and success of our clinical development programs, regulatory and market acceptance, and the resources 
we  devote  to  research  and  commercialization  activities. The  amount  of  cash  on  hand  will  depend  on  the  progress  of  various 
preclinical and clinical programs, the timing of our manufacturing scale-up and the achievement of various milestones and royalties 
under our existing collaborative agreements.

We believe that our current cash, cash equivalents and marketable securities will be sufficient to fund our operations for at 
least the next twelve months. We expect to fund our operations going forward with existing cash resources, anticipated revenues 
from our existing collaborations and cash that we may raise through future transactions. We may raise cash through any one of 
the following financing vehicles: (i) the public offering of securities; (ii) new collaborative agreements; (iii) expansions or revisions 
to existing collaborative relationships; (iv) private financings; (v) other equity or debt financings; and/or (vi) monetizing assets.

We are a “well known seasoned issuer”, which allows us to file an automatically effective shelf registration statement on 
Form S-3 which would allow us, from time to time, to offer and sell equity, debt securities and warrants to purchase any of such 
securities, either individually or in units. We may, in the future, offer and sell equity, debt securities and warrants to purchase any 
of such securities, either individually or in units to raise capital to fund the continued development of our product candidates, the 
commercialization of our products or for other general corporate purposes. 

Our existing cash, cash equivalents and marketable securities may not be adequate to fund our operations until we become 
profitable, if ever. We cannot be certain that additional financing will be available when needed or, if available, financing will be 
obtained on favorable terms. If we are unable to raise sufficient funds, we may need to delay, scale back or eliminate some or all 
of our research and development programs, delay the launch of our product candidates, if approved, and/or restructure our operations. 
If we raise additional funds by issuing equity securities, substantial dilution to existing stockholders could result. If we raise 
additional funds by incurring debt financing, the terms of the debt may involve significant cash payment obligations, the issuance 
of warrants that may ultimately dilute existing stockholders when exercised and covenants that may restrict our ability to operate 
our business.

Cash Flows

Operating Activities

Net cash used in operations was $50.4 million in 2016 compared to $37.1 million in 2015. The $13.3 million increase in 
utilization of cash in operations was mainly due to an increase in operating losses compared to the prior year, partially offset by 
the timing of the collection of accounts receivable.

Net cash used in operations was $37.1 million in 2015 compared to $47.5 million in 2014. The $10.4 million decrease in 
utilization of cash in operations resulted from lower operating losses, mainly due to an increase of license fees and royalties from 
our collaborators offset in part by increased spending on our R&D programs. Our lower operating losses were offset by increases 
in working capital including accounts receivable, prepaid expenses and inventory, offset by increases in accounts payable. 

36

Investing Activities

Net cash used in investing activities was $76.8 million in 2016 compared to net cash provided of $5.9 million in 2015 and 
net cash used of $33.0 million in 2014. The change in 2016 compared to 2015 was primarily due to net purchases of marketable 
securities using the proceeds from the Royalty-backed Loan. The change in 2015 compared to 2014 was primarily due to net sales 
of marketable securities to fund operations in 2015 compared to net purchases of marketable securities during 2014 using the 
proceeds from issuing shares of our common stock.

Financing Activities

Net cash provided by financing activities was $150.6 million in 2016 compared to $13.1 million in 2015 and $114.5 million
in 2014. Net cash provided by financing activities in 2016 consisted primarily of net proceeds of $148.0 million from the Royalty-
backed Loan and $55.0 million from a new Oxford and SVB Loan, partially offset by principal payments and a final payment of 
$54.3 million on a previously existing Oxford and SVB Loan. Net cash provided by financing activities in 2015 consisted of $13.1 
million in net proceeds from options exercised. Net cash provided by financing activities in 2014 consisted of $107.7 million in 
net proceeds from the sale of our common stock in February 2014 and $6.8 million in net proceeds from option exercises. 

Long-Term Debt

Royalty-backed Loan

In January 2016, through our wholly-owned subsidiary Halozyme Royalty, we received a $150 million loan (the Royalty-
backed Loan) pursuant to a credit agreement (the Credit Agreement) with BioPharma Credit Investments IV Sub, LP and Athyrium 
Opportunities II Acquisition LP (the Royalty-backed Lenders). Under the terms of the Credit Agreement, Halozyme Therapeutics, 
Inc. transferred to Halozyme Royalty the right to receive royalty payments from the commercial sales of ENHANZE products 
owed  under  the  Roche  Collaboration  and  Baxalta  Collaboration  (Collaboration Agreements). The  royalty  payments  from  the 
Collaboration Agreements will be used to repay the principal and interest on the loan (the Royalty Payments).  The Royalty-backed 
Loan bears interest at a per annum rate of 8.75% plus the three-month LIBOR rate. The three-month LIBOR rate is subject to a 
floor of 0.7% and a cap of 1.5%. The interest rate as of December 31, 2016 was 9.71%. The outstanding balance of the Royalty-
backed Loan as of December 31, 2016 was $161.8 million, inclusive of payment-in-kind interest expense of $13.2 million and net 
of unamortized debt discount of $1.4 million.

The Credit Agreement provides that none of the Royalty Payments are required to be applied to the Royalty-backed Loan 
prior to January 1, 2017, 50% of the Royalty Payments are required to be applied to the Royalty-backed Loan between January 1, 
2017 and January 1, 2018 and thereafter all Royalty Payments must be applied to the Royalty-backed Loan. However, the amounts 
available to repay the Royalty-backed Loan are subject to caps of $13.75 million per quarter in 2017, $18.75 million per quarter 
in 2018, $21.25 million per quarter in 2019 and $22.5 million per quarter in 2020 and thereafter. Amounts available to repay the 
Royalty-backed Loan will be applied first, to pay interest and second, to repay principal on the Royalty-backed Loan. Any accrued 
interest that is not paid on any applicable quarterly payment date, as defined, will be capitalized and added to the principal balance 
of the Royalty-backed Loan on such date. Halozyme Royalty will be entitled to receive and distribute to Halozyme any Royalty 
Payments that are not required to be applied to the Royalty-backed Loan or which are in excess of the foregoing caps. 

The final maturity date of the Royalty-backed Loan will be the earlier of (i) the date when principal and interest is paid in 
full,  (ii) the  termination  of  Halozyme  Royalty’s  right  to  receive  royalties  under  the  Collaboration  Agreements,  and 
(iii) December 31, 2050.  Under the terms of the Credit Agreement, at any time after January 1, 2019, Halozyme Royalty may, 
subject to certain limitations, prepay the outstanding principal of the Royalty-backed Loan in whole or in part, at a price equal to 
105%  of  the  outstanding  principal  on  the  Royalty-backed  Loan,  plus  accrued  but  unpaid  interest. The  Royalty-backed  Loan 
constitutes an obligation of Halozyme Royalty, and is non-recourse to Halozyme. Halozyme Royalty retains its right to the Royalty 
Payments following repayment of the loan. 

Oxford and SVB Loan and Security Agreement

In December 2013, we entered into an Amended and Restated Loan and Security Agreement (the Original Loan Agreement) 
with Oxford Finance LLC (Oxford) and Silicon Valley Bank (SVB) (collectively, the Lenders), amending and restating in its 
entirety our previous loan agreement with the Lenders, dated December 2012. The Loan Agreement provided for an additional 
$20 million principal amount of new term loan, bringing the total term loan balance to $50 million. The amended term loan facility 
was scheduled to mature on January 1, 2018. 

37

In January 2015, we and the Lenders entered into a second amendment to the Original Loan Agreement amending and 
restating the loan repayment schedule of the Original Loan Agreement. The amended and restated loan repayment schedule provided 
for interest only payments in arrears through January 2016, followed by consecutive equal monthly payments of principal and 
interest in arrears starting in February 2016 and continuing through the previously established maturity date. Consistent with the 
original loan, the amended Original Loan Agreement provided for a 7.55% interest rate on the term loan and a final payment equal 
to 8.5% of the original principal amount, or $4.25 million, which was due when the term loan became due or upon the prepayment 
of the facility. 

In June 2016, we entered into a new Loan and Security Agreement (the New Loan Agreement) with the Lenders, providing 
a senior secured loan facility of up to an aggregate principal amount of $70 million, comprising a $55.0 million draw in June 2016 
and an additional $15.0 million tranche, which we have the option to draw during the second quarter of 2017. The proceeds were 
partially used to pay the outstanding principal and final payment owed on the amended Original Loan Agreement. The remaining 
proceeds, including any drawdown of the additional $15.0 million available to us, are to be used for working capital and general 
business requirements. We have the option to draw the remaining $15 million during the second quarter of 2017 at an annual 
interest rate equal to the then-current prime rate as reported in The Wall Street Journal plus 4.75%. The New Loan Agreement 
repayment schedule provides for interest only payments for the first 18 months, followed by consecutive equal monthly payments 
of principal and interest in arrears through the maturity date of January 1, 2021. The New Loan Agreement provides for a final 
payment equal to 5.50% of the initial $55 million principal amount and, if we exercise our option to draw an additional $15 million 
in 2017, 7.25% of the principal amount of the second draw. The final payment is due when the New Loan Agreement becomes 
due or upon the prepayment of the facility. We have the option to prepay the outstanding balance of the New Loan Agreement in 
full, subject to a prepayment fee of 2% in the first year and 1% in the second year of the term loan. The outstanding New Loan 
Agreement balance was $54.8 million as of December 31, 2016.

The New Loan Agreement is secured by substantially all of the assets of the Company and its subsidiary, Halozyme, Inc., 
except  that  the  collateral  does  not  include  any  equity  interests  in  Halozyme,  Inc.  and  any  intellectual  property  (including  all 
licensing, collaboration and similar agreements relating thereto), and certain other excluded assets. The New Loan Agreement 
contains customary representations, warranties and covenants by us, which covenants limit our ability to convey, sell, lease, transfer, 
assign or otherwise dispose of certain of our assets; engage in any business other than the businesses currently engaged in by us 
or reasonably related thereto; liquidate or dissolve; make certain management changes; undergo certain change of control events; 
create, incur, assume, or be liable with respect to certain indebtedness; grant certain liens; pay dividends and make certain other 
restricted payments; make certain investments; make payments on any subordinated debt; enter into transactions with any of our 
affiliates outside of the ordinary course of business or permit our subsidiaries to do the same; and make any voluntary prepayment 
of or modify certain terms of the Royalty-backed Loan. In addition, subject to certain exceptions, we are required to maintain with 
SVB our primary deposit accounts, securities accounts and commodities, and to do the same for our domestic subsidiary. 

The New Loan Agreement also contains customary indemnification obligations and customary events of default, including, 
among other things, our failure to fulfill certain of our obligations under the New Loan Agreement and the occurrence of a material 
adverse change which is defined as a material adverse change in our business, operations or condition (financial or otherwise), a 
material impairment of the prospect of repayment of any portion of the loan, a material impairment in the perfection or priority 
of the Lender’s lien in the collateral or in the value of such collateral or the occurrence of an event of default under the Royalty-
backed Loan. In the event of default by us under the New Loan Agreement, the Lenders would be entitled to exercise their remedies 
thereunder, including the right to accelerate the debt, upon which we may be required to repay all amounts then outstanding under 
the New Loan Agreement, which could harm our financial condition.

Off-Balance Sheet Arrangements

As of December 31, 2016, we did not have any relationships with unconsolidated entities or financial partnerships, such as 
entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of 
facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. In addition, we did not engage in 
trading activities involving non-exchange traded contracts. As such, we are not materially exposed to any financing, liquidity, 
market or credit risk that could arise if we had engaged in such relationships.

(1)  Does not include milestone or contractual payment obligations contingent upon the achievement of certain milestones 
or events if the amount and timing of such obligations are unknown or uncertain. Our in-license agreement is cancelable 
with written notice within 90 days. We may be required to pay up to approximately $8.0 million in milestone payments, 
plus  sales  royalties,  in  the  event  that  all  scientific  research  under  these  agreements  is  successful. Also  excludes 
contractual obligations already recorded on our consolidated balance sheet as current liabilities.

(2)  Long-term  debt  obligations  include  future  monthly  interest  payments  for  the  Oxford  and  SVB  Loan  and  Security 
Agreement based on a fixed rate of 8.25% and a final payment of $3.03 million for our long-term debt due in January 
2021. Long-term debt obligations also include future quarterly interest and principal payments for the Royalty-backed 
Loan based on an estimate of future royalty amounts. This estimate could be adversely affected and the repayment 
period could be extended if future royalty amounts are less than currently expected. The Royalty-backed loan bears 
interest at a per annum rate of 8.75% plus the three-month LIBOR rate. The three-month LIBOR rate is subject to a 
floor of 0.7% and a cap of 1.5%. Future interest payments will increase if the LIBOR rate increases. 

(3) 

Includes minimum lease payments related to leases of our office and research facilities and certain autos under non-
cancelable operating leases.

(4)  We  have  contracted  with  third-party  manufacturers  for  the  supply  of  bulk  rHuPH20  and  fill/finish  of  Hylenex 
recombinant. Under these agreements, we are required to purchase certain quantities each year during the terms of the 
agreements. The amounts presented represent our estimates of the minimum required payments under these agreements. 

Contractual obligations for purchases of goods or services include agreements that are enforceable and legally binding to 
us and that specify all significant terms, including fixed or minimum quantities to be purchased; fixed, minimum or variable price 
provisions; and the approximate timing of the transaction. For obligations with cancellation provisions, the amounts included in 
the preceding table were limited to the non-cancelable portion of the agreement terms or the minimum cancellation fee.

For certain restricted stock units and performance stock units granted, the number of shares issued on the date the restricted 
stock units vest is net of the minimum statutory withholding requirements that we pay in cash to the appropriate taxing authorities 
on behalf of our employees. The obligation to pay the relevant taxing authority is not included in the preceding table, as the amount 
is contingent upon continued employment. In addition, the amount of the obligation is unknown, as it is based in part on the market 
price of our common stock when the awards vest.

The expected timing of payments of the obligations above is estimated based on current information. Timing of payments 
and actual amounts paid may be different, depending on the time of receipt of goods or services, or changes to agreed-upon amounts 
for some obligations.

39

 
Our future capital uses and requirements depend on numerous forward-looking factors. These factors may include, but are 

not limited to, the following:

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

the rate of progress and cost of research and development activities;

the number and scope of our research activities;

the costs of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights;

our ability to establish and maintain product discovery and development collaborations, including scale-up manufacturing 
costs for our collaborators’ product candidates;

the amount of royalties from our collaborators;

the amount of product sales for Hylenex recombinant;

the costs of obtaining and validating additional manufacturers of Hylenex recombinant;

the effect of competing technological and market developments;

the terms and timing of any collaborative, licensing and other arrangements that we may establish; and

the extent to which we acquire or in-license new products, technologies or businesses.

Critical Accounting Estimates

The discussion and analysis of our financial condition and results of operations are based on our consolidated financial 
statements, which have been prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP. The 
preparation of our consolidated financial statements requires us to make estimates and judgments that affect the reported amounts 
of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. We review our estimates on 
an ongoing basis. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable 
under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. 
Actual results may differ from these estimates under different assumptions or conditions. We believe the following accounting 
policies to be critical to the judgments and estimates used in the preparation of our consolidated financial statements.

Revenue Recognition

We generate revenues from product sales and collaborative agreements. Payments received under collaborative agreements 
may include nonrefundable fees at the inception of the agreements, license fees, milestone payments for specific achievements 
designated in the collaborative agreements, reimbursements of research and development services and supply of bulk rHuPH20 
and/or royalties on sales of products resulting from collaborative arrangements.

We recognize revenue in accordance with the authoritative guidance on revenue recognition. Revenue is recognized when 
all of the following criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have 
been rendered; (3) the seller’s price to the buyer is fixed or determinable; and (4) collectibility is reasonably assured.

Refer to Note 2, Summary of Significant Accounting Policies, of our consolidated financial statements for further discussion 
of our revenue recognition policies for product sales and revenues under our collaborative agreements and Note 4, Collaborative 
Agreements, of our consolidated financial statements for a further discussion of our collaborative agreements.

Share-Based Payments

We use the fair value method to account for share-based payments in accordance with the authoritative guidance for share-
based compensation. The fair value of each option award is estimated on the date of grant using a Black-Scholes-Merton option 
pricing model (Black-Scholes model) that uses assumptions regarding a number of complex and subjective variables. Changes in 
these assumptions may lead to variability with respect to the amount of expense we recognize in connection with share-based 
payments. Refer to Note 2, Summary of Significant Accounting Policies, of our consolidated financial statements for a further 
discussion of share-based payments.

40

Research and Development Expenses

Research and development expenses include salaries and benefits, facilities and other overhead expenses, external clinical 
trial expenses, research related manufacturing services, contract services and other outside expenses. Research and development 
expenses are charged to operating expenses as incurred when these expenditures relate to our research and development efforts 
and have no alternative future uses. After receiving marketing approval from the FDA or comparable regulatory agencies in foreign 
countries for a product, costs related to purchases or manufacturing of bulk rHuPH20 for such product are capitalized as inventory. 
The manufacturing costs of bulk rHuPH20 for the collaboration products, Herceptin SC, MabThera SC and HYQVIA, which were 
incurred after the receipt of marketing approvals are capitalized as inventory. Refer to Note 2, Summary of Significant Accounting 
Policies, of our consolidated financial statements for a further discussion of research and development expenses.

Due to the uncertainty in obtaining the FDA and other regulatory approvals, our reliance on third parties and competitive 
pressures, we are unable to estimate with any certainty the additional costs we will incur in the continued development of our 
proprietary product candidates for commercialization. However, we expect our research and development expenses to increase 
this year as we continue with our clinical trial programs and continue to develop and manufacture our product candidates.

Clinical development timelines, likelihood of success and total costs vary widely. We anticipate that we will make ongoing 
determinations as to which research and development projects to pursue and how much funding to direct to each project on an 
ongoing basis in response to existing resource levels, the scientific and clinical progress of each product candidate, and other 
market and regulatory developments. We plan on focusing our resources on those proprietary and collaboration product candidates 
that represent the most valuable economic and strategic opportunities.

Product candidate completion dates and costs vary significantly for each product candidate and are difficult to estimate. The 
lengthy process of seeking regulatory approvals and the subsequent compliance with applicable regulations require the expenditure 
of substantial resources. Any failure by us to obtain, or any delay in obtaining, regulatory approvals could cause our research and 
development expenditures to increase and, in turn, have a material adverse effect on our results of operations. We cannot be certain 
when,  or  if,  our  product  candidates  will  receive  regulatory  approval  or  whether  any  net  cash  inflow  from  our  other  product 
candidates, or development projects, will commence.

Recent Accounting Pronouncements

Refer to Note 2, Summary of Significant Accounting Policies, of our consolidated financial statements for a discussion of 

recent accounting pronouncements and their effect, if any, on us.

Item 7A.  Quantitative and Qualitative Disclosures About Market Risk

As of December 31, 2016, our cash equivalents and marketable securities consisted of investments in money market funds, 
U.S. Treasury securities, corporate debt obligations and commercial paper. These investments were made in accordance with our 
investment policy which specifies the categories, allocations, and ratings of securities we may consider for investment. The primary 
objective of our investment activities is to preserve principal while at the same time maximizing the income we receive without 
significantly increasing risk. Some of the financial instruments that we invest in could be subject to market risk. This means that 
a change in prevailing interest rates may cause the value of the instruments to fluctuate. For example, if we purchase a security 
that was issued with a fixed interest rate and the prevailing interest rate later rises, the value of that security will probably decline. 
Based on our current investment portfolio as of December 31, 2016, we do not believe that our results of operations would be 
materially impacted by an immediate change of 10% in interest rates. 

We do not hold or issue derivatives, derivative commodity instruments or other financial instruments for speculative trading 
purposes.  Further,  we  do  not  believe  our  cash,  cash  equivalents  and  marketable  securities  have  significant  risk  of  default  or 
illiquidity. We made this determination based on discussions with our investment advisors and a review of our holdings. While 
we believe our cash, cash equivalents and marketable securities do not contain excessive risk, we cannot provide absolute assurance 
that in the future our investments will not be subject to adverse changes in market value. All of our cash equivalents and marketable 
securities are recorded at fair market value.

Item 8.  Financial Statements and Supplementary Data

Item 9A. Control and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our 
Exchange Act reports is recorded, processed, summarized and reported within the timelines specified in the Securities and Exchange 
Commission’s rules and forms, and that such information is accumulated and communicated to our management, including our 
Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decision regarding required disclosure. In 
designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no 
matter how well designed and operated, can only provide reasonable assurance of achieving the desired control objectives, and in 
reaching a reasonable level of assurance, management necessarily was required to apply its judgment in evaluating the cost-benefit 
relationship of possible controls and procedures.

Under the supervision and with the participation of our management, including our principal executive officer and principal 
financial officer, we conducted an evaluation of our disclosure controls and procedures, as such term is defined under Rule 13a-15
(e) promulgated under the Securities Exchange Act of 1934, as amended. Based on this evaluation, our principal executive officer 
and our principal financial officer concluded that our disclosure controls and procedures were effective as of the end of the period 
covered by this Annual Report on Form 10-K.

Changes in Internal Control Over Financial Reporting

There have been no significant changes in our internal control over financial reporting that occurred during the quarter ended 
December 31, 2016 that have materially affected, or are reasonably likely to materially affect, our internal control over financial 
reporting.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal 
control over financial reporting is defined in Rule 13a-15(f) and Rule 15d-15(f) promulgated under the Exchange Act as a process 
designed by, or under the supervision of, our principal executive and principal financial officers and effected by our board of 
directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and 
the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and 
includes those policies and procedures that:

• 

• 

• 

Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions 
of our assets;

Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in 
accordance  with  generally  accepted  accounting  principles,  and  that  receipts  and  expenditures  are  being  made  only  in 
accordance with authorizations of our management and directors; and

Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of 
our assets that could have a material effect on our financial statements.

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

The independent registered public accounting firm that audited the consolidated financial statements that are included in 
this Annual Report on Form 10-K has issued an audit report on the effectiveness of our internal control over financial reporting 
as of December 31, 2016. The report appears below.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders
Halozyme Therapeutics, Inc.

We have audited Halozyme Therapeutics, Inc.’s internal control over financial reporting as of December 31, 2016, based on 
criteria  established  in  Internal  Control  -  Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the 
Treadway Commission (2013 framework) (the COSO criteria). Halozyme Therapeutics, Inc.’s management is responsible for 
maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over 
financial  reporting  included  in  the  accompanying  Management’s  Report  on  Internal  Control  Over  Financial  Reporting.  Our 
responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.

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

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

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because 
of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Halozyme Therapeutics, Inc. maintained, in all material respects, effective internal control over financial 

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

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), 
the consolidated balance sheets of Halozyme Therapeutics, Inc. as of December 31, 2016 and 2015, and the related consolidated 
statements of operations, comprehensive loss, cash flows, and stockholders’ (deficit) equity for each of the three years in the period 
ended December 31, 2016 of Halozyme Therapeutics, Inc. and our report dated February 28, 2017 expressed an unqualified opinion 
thereon.

                                                                                                   /s/    Ernst & Young LLP

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders
Halozyme Therapeutics, Inc.

We have audited the accompanying consolidated balance sheets of Halozyme Therapeutics, Inc. as of December 31, 2016 
and 2015, and the related consolidated statements of operations, comprehensive loss, cash flows, and stockholders’ (deficit) equity 
for each of the three years in the period ended December 31, 2016.  Our audits also included the financial statement schedule listed 
in the Index at Item 15(a). These financial statements and schedule are the responsibility of the Company’s management. Our 
responsibility is to express an opinion on these financial statements and schedule based on our audits.

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

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial 
position of Halozyme Therapeutics, Inc. at December 31, 2016 and 2015, and the consolidated results of its operations and its cash 
flows for each of the three years in the period ended December 31, 2016, in conformity with U.S. generally accepted accounting 
principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements 
taken as a whole, presents fairly in all material respects the information set forth therein.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company Accounting  Oversight  Board  (United 
States), Halozyme  Therapeutics,  Inc.’s  internal  control  over  financial  reporting  as  of  December 31,  2016,  based  on  criteria 
established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (2013 framework) and our report dated February 28, 2017 expressed an unqualified opinion thereon.

Notes to Consolidated Financial Statements

1.  Organization and Business

Halozyme Therapeutics,  Inc.  is  a  biotechnology  company  focused  on  developing  and  commercializing  novel  oncology 
therapies. We are seeking to translate our unique knowledge of the tumor microenvironment to create therapies that have the 
potential to improve cancer patient survival. Our research primarily focuses on human enzymes that alter the extracellular matrix 
and tumor microenvironment. The extracellular matrix is a complex matrix of proteins and carbohydrates surrounding the cell that 
provides structural support in tissues and orchestrates many important biological activities, including cell migration, signaling and 
survival. Over many years, we have developed unique technology and scientific expertise enabling us to pursue this target-rich 
environment for the development of therapies.

Our proprietary enzymes are used to facilitate the delivery of injected drugs and fluids, potentially enhancing the efficacy 
and the convenience of other drugs or can be used to alter tissue structures for potential clinical benefit. We exploit our technology 
and expertise using a two pillar strategy that we believe enables us to manage risk and cost by: (1) developing our own proprietary 
products in therapeutic areas with significant unmet medical needs, with a focus on oncology, and (2) licensing our technology to 
biopharmaceutical companies to collaboratively develop products that combine our technology with the collaborators’ proprietary 
compounds.

The majority of our approved product and product candidates are based on rHuPH20, our patented recombinant human 
hyaluronidase enzyme. rHuPH20 is the active ingredient in our first commercially approved product, Hylenex® recombinant, and 
it works by temporarily breaking down hyaluronan (or “HA”), a naturally occurring complex carbohydrate that is a major component 
of the extracellular matrix in tissues throughout the body such as skin and cartilage. We believe this temporary degradation creates 
an opportunistic window for the improved subcutaneous delivery of injectable biologics, such as monoclonal antibodies and other 
large therapeutic molecules, as well as small molecules and fluids. We refer to the application of rHuPH20 to facilitate the delivery 
of other drugs or fluids as our ENHANZE™ Technology. We license the ENHANZE Technology to form collaborations with 
biopharmaceutical companies that develop or market drugs requiring or benefiting from injection via the subcutaneous route of 
administration.

We currently have ENHANZE collaborations with F. Hoffmann-La Roche, Ltd. and Hoffmann-La Roche, Inc. (“Roche”), 
Baxalta US Inc. and Baxalta GmbH (Baxalta Incorporated was acquired by Shire plc in June 2016) (“Baxalta”), Pfizer Inc. (“Pfizer”), 
Janssen Biotech, Inc. (“Janssen”), AbbVie, Inc. (“AbbVie”), and Eli Lilly and Company (“Lilly”). We receive royalties from two 
of these collaborations, including royalties from sales of one product approved in both the United States and outside the United 
States from the Baxalta collaboration and from sales of two products approved for marketing outside the United States from the 
Roche collaboration. Future potential revenues from the sales and/or royalties of our approved products, product candidates, and 
ENHANZE collaborations will depend on the ability of Halozyme and our collaborators to develop, manufacture, secure and 
maintain regulatory approvals for approved products and product candidates and commercialize product candidates.

Our proprietary development pipeline consists primarily of pre-clinical and clinical stage product candidates in oncology. 
Our lead oncology program is PEGPH20 (PEGylated recombinant human hyaluronidase), a molecular entity we are developing 
in combination with currently approved cancer therapies as a candidate for the systemic treatment of tumors that accumulate HA. 
We have demonstrated that when HA accumulates in a tumor, it can cause higher pressure in the tumor, reducing blood flow into 
the tumor and with that, reduced access of cancer therapies to the tumor. PEGPH20 has been demonstrated in animal models to 
work by temporarily degrading HA surrounding cancer cells resulting in reduced pressure and increased blood flow to the tumor 
thereby enabling increased amounts of anticancer treatments administered concomitantly gaining access to the tumor. Through 
our efforts and efforts of our partners and collaborators, we are currently in Phase 2 and Phase 3 clinical testing for PEGPH20 
with ABRAXANE® (nab-paclitaxel) and gemcitabine in stage IV pancreatic ductal adenocarcinoma (“PDA”) (Studies 109-202 
and 109-301), in Phase 1b clinical testing for PEGPH20 with KEYTRUDA® (pembrolizumab) in non-small cell lung cancer and 
gastric cancer (Study 107-101) and in Phase 1b/2 clinical testing for PEGPH20 with HALAVEN® (eribulin) in patients treated 
with up to two lines of prior therapy for HER2-negative metastatic breast cancer.

Summary of Significant Accounting Policies

Basis of Presentation

The consolidated financial statements include the accounts of Halozyme Therapeutics, Inc. and our wholly owned subsidiary, 
Halozyme, Inc., and Halozyme, Inc.’s wholly owned subsidiaries, Halozyme Holdings Ltd., Halozyme Royalty LLC and Halozyme 
Switzerland GmbH. All intercompany accounts and transactions have been eliminated.

Use of Estimates

The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles (“U.S. 
GAAP”) requires management to make estimates and assumptions that affect the amounts reported in our consolidated financial 
statements and accompanying notes. On an ongoing basis, we evaluate our estimates and judgments, which are based on historical 
and  anticipated  results  and  trends  and  on  various  other  assumptions  that  management  believes  to  be  reasonable  under  the 
circumstances. By their nature, estimates are subject to an inherent degree of uncertainty and, as such, actual results may differ 
from management’s estimates.

Cash Equivalents and Marketable Securities

Cash equivalents consist of highly liquid investments, readily convertible to cash, that mature within ninety days or less from 

date of purchase. Our cash equivalents consist of money market funds.

Marketable securities are investments with original maturities of more than ninety days from the date of purchase that are 
specifically identified to fund current operations. Marketable securities are considered available-for-sale. These investments are 
classified as current assets, even though the stated maturity date may be one year or more beyond the current balance sheet date 
which reflects management’s intention to use the proceeds from the sale of these investments to fund our operations, as necessary. 
Such available-for-sale investments are carried at fair value with unrealized gains and losses recorded in other comprehensive gain 
(loss) and included as a separate component of stockholders’ (deficit) equity. The cost of marketable securities is adjusted for 
amortization of premiums or accretion of discounts to maturity, and such amortization or accretion is included in investment and 
other income, net in the consolidated statements of operations. We use the specific identification method for calculating realized 
gains and losses on marketable securities sold. Realized gains and losses and declines in value judged to be other-than-temporary 
on marketable securities, if any, are included in investment and other income, net in the consolidated statements of operations.

Restricted Cash

Under the terms of the leases on our facilities, we are required to maintain letters of credit as security deposits during the 
terms of such leases. At December 31, 2016 and 2015, restricted cash of $0.5 million was pledged as collateral for the letters of 
credit.

Fair Value of Financial Instruments

The authoritative guidance for fair value measurements establishes a three tier fair value hierarchy, which prioritizes the 
inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices in active 
markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and 
Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own 
assumptions. 

Our financial instruments include cash equivalents, available-for-sale marketable securities, accounts receivable, prepaid 
expenses and other assets, accounts payable, accrued expenses and long-term debt. Fair value estimates of these instruments are 
made at a specific point in time, based on relevant market information. These estimates may be subjective in nature and involve 
uncertainties and matters of significant judgment and therefore cannot be determined with precision. The carrying amount of cash 
equivalents, accounts receivable, prepaid expenses and other assets, accounts payable and accrued expenses are generally considered 
to be representative of their respective fair values because of the short-term nature of those instruments. Further, based on the 
borrowing rates currently available for loans with similar terms, we believe the fair value of long-term debt approximates its 
carrying value.

Notes to Consolidated Financial Statements — (Continued)

Available-for-sale marketable securities consist of corporate debt securities, U.S. Treasury securities and commercial paper, 
and are measured at fair value using Level 1 and Level 2 inputs. Level 2 financial instruments are valued using market prices on 
less active markets and proprietary pricing valuation models with observable inputs, including interest rates, yield curves, maturity 
dates, issue dates, settlement dates, reported trades, broker-dealer quotes, issue spreads, benchmark securities or other market 
related data. We obtain the fair value of Level 2 investments from our investment manager, who obtains these fair values from a 
third-party pricing source. We validate the fair values of Level 2 financial instruments provided by our investment manager by 
comparing these fair values to a third-party pricing source.

The following table summarizes, by major security type, our cash equivalents and marketable securities that are measured 

at fair value on a recurring basis and are categorized using the fair value hierarchy (in thousands):

There were no transfers between Level 1 and Level 2 of the fair value hierarchy for the years ended December 31, 2016 and 

2015. We have no instruments that are classified within Level 3 as of December 31, 2016 and 2015.

Concentrations of Credit Risk, Sources of Supply and Significant Customers

We are subject to credit risk from our portfolio of cash equivalents and marketable securities. These investments were made 
in accordance with our investment policy which specifies the categories, allocations, and ratings of securities we may consider 
for investment. The primary objective of our investment activities is to preserve principal while at the same time maximizing the 
income  we  receive  without  significantly  increasing  risk. We  maintain  our  cash  and  cash  equivalent  balances  with  one  major 
commercial bank and marketable securities with another financial institution. Deposits held with the financial institutions exceed 
the amount of insurance provided on such deposits. We are exposed to credit risk in the event of a default by the financial institutions 
holding our cash, cash equivalents and marketable securities to the extent recorded on the consolidated balance sheets. 

We are also subject to credit risk from our accounts receivable related to our product sales and revenues under our license 
and collaborative agreements. We have license and collaborative agreements with pharmaceutical companies under which we 
receive  payments  for  license  fees,  milestone  payments  for  specific  achievements  designated  in  the  collaborative  agreements, 
reimbursements of research and development services and supply of bulk formulation of rHuPH20. In addition, we sell Hylenex®
recombinant in the United States to a limited number of established wholesale distributors in the pharmaceutical industry. Credit 
is extended based on an evaluation of the customer’s financial condition, and collateral is not required. Management monitors our 
exposure to accounts receivable by periodically evaluating the collectibility of the accounts receivable based on a variety of factors 
including the length of time the receivables are past due, the financial health of the customer and historical experience. Based upon 
the review of these factors, we recorded no allowance for doubtful accounts at December 31, 2016 and 2015. Approximately 81%
of the accounts receivable balance at December 31, 2016 represents amounts due from Roche and Baxalta. Approximately 89%
of the accounts receivable balance at December 31, 2015 represents amounts due from Roche and Lilly.

As of December 31, 2016 and 2015, we had $0.1 million and $0.3 million, respectively, of research equipment in Germany.

We rely on two third-party manufacturers for the supply of bulk rHuPH20 for use in the manufacture of Hylenex recombinant 
and our other collaboration products and product candidates. Payments due to these suppliers represented 13% and 20% of the 
accounts payable balance at December 31, 2016 and 2015, respectively. We also rely on a third-party manufacturer for the fill and 
finish of Hylenex recombinant product under a contract. Payments due to this supplier represented 2% and 4% of the accounts 
payable balance at December 31, 2016 and 2015, respectively.

Accounts Receivable, Net

Accounts receivable is recorded at the invoiced amount and is non-interest bearing. Accounts receivable is recorded net of 
allowances for doubtful accounts, cash discounts for prompt payment, distribution fees and chargebacks. We recorded no allowance 
for doubtful accounts at December 31, 2016 and 2015 as the collectibility of accounts receivable was reasonably assured.

Inventories

Inventories are stated at lower of cost or market. Cost is determined on a first-in, first-out basis. Inventories are reviewed 
periodically for potential excess, dated or obsolete status. We evaluate the carrying value of inventories on a regular basis, taking 
into account such factors as historical and anticipated future sales compared to quantities on hand, the price we expect to obtain 
for products in their respective markets compared with historical cost and the remaining shelf life of goods on hand.

Prior to receiving marketing approval from the U.S. Food and Drug Administration (“FDA”) or comparable regulatory 
agencies in foreign countries, costs related to purchases of bulk rHuPH20 and raw materials and the manufacturing of the product 
candidates are recorded as research and development expense. All direct manufacturing costs incurred after receiving marketing 
approval are capitalized as inventory. Inventories used in clinical trials are expensed at the time the inventories are packaged for 
the clinical trials.

As of December 31, 2016 and 2015, inventories consisted of $2.3 million and $1.4 million of Hylenex recombinant inventory, 
respectively, and $12.3 million and $8.2 million of bulk rHuPH20, respectively, for use in the manufacture of Balxalta’s and 
Roche’s collaboration products.

Notes to Consolidated Financial Statements — (Continued)

Property and Equipment, Net

Property and equipment are recorded at cost, less accumulated depreciation and amortization. Equipment is depreciated 
using the straight-line method over their estimated useful lives of three years and leasehold improvements are amortized using the 
straight-line method over the estimated useful life of the asset or the lease term, whichever is shorter. Leased buildings under build-
to-suit lease arrangements are capitalized and included in property and equipment when we are involved in the construction of the 
structural improvements or take construction risk prior to the commencement of the lease. Upon completion of the construction 
under  the  build-to-suit  leases,  we  assess  whether  those  arrangements  qualify  for  sales  recognition  under  the  sale-leaseback 
accounting guidance. If we continue to be the deemed owner, the facilities would be accounted for as financing leases.

Impairment of Long-Lived Assets

We account for long-lived assets in accordance with authoritative guidance for impairment or disposal of long-lived assets. 
Long-lived  assets  are  reviewed  for  events  or  changes  in  circumstances,  which  indicate  that  their  carrying  value  may  not  be 
recoverable. For the years ended December 31, 2016 and 2015, there was no impairment of the value of long-lived assets.

Deferred Rent

Rent expense is recorded on a straight-line basis over the initial term of the lease. The difference between rent expense 
accrued and amounts paid under lease agreements is recorded as deferred rent and is included in accrued expenses and other long-
term liabilities, as applicable, in the accompanying consolidated balance sheets.

Comprehensive Income (Loss)

Comprehensive income (loss) is defined as the change in equity during the period from transactions and other events and 

circumstances from non-owner sources. 

Revenue Recognition

We generate revenues from product sales and payments received under collaborative agreements. Collaborative agreement 
payments may include nonrefundable fees at the inception of the agreements, license fees, milestone and event-based payments 
for specific achievements designated in the collaborative agreements, reimbursements of research and development services and 
supply of bulk rHuPH20, and/or royalties on sales of products resulting from collaborative arrangements.

We recognize revenues in accordance with the authoritative guidance for revenue recognition. We recognize revenue when 
all of the following criteria are met: (1) persuasive evidence of an arrangement exists; (2) delivery has occurred or services have 
been rendered; (3) the seller’s price to the buyer is fixed or determinable; and (4) collectibility is reasonably assured.

Product Sales, Net

Hylenex Recombinant

We sell Hylenex recombinant in the U.S. to wholesale pharmaceutical distributors, who sell the product to hospitals and other end-
user customers. Sales to wholesalers provide for selling prices that are fixed on the date of sale, although we offer discounts to 
certain group purchasing organizations (“GPOs”), hospitals and government programs. The wholesalers take title to the product, 
bear the risk of loss of ownership and have economic substance to the inventory. Further, we have no significant obligations for 
future performance to generate pull-through sales.

We have developed sufficient historical experience and data to reasonably estimate future returns and chargebacks of Hylenex
recombinant. As a result, we recognize Hylenex recombinant product sales and related cost of product sales at the time title transfers 
to the wholesalers.

Upon recognition of revenue from product sales of Hylenex recombinant, we record certain sales reserves and allowances 

as a reduction to gross revenue. These reserves and allowances include:

•  Product Returns. We allow the wholesalers to return product that is damaged or received in error. In addition, we 
accept unused product to be returned beginning six months prior to and ending twelve months following product 
expiration. Our estimates for expected returns of expired products are based primarily on an ongoing analysis of 
historical return patterns.

•  Distribution Fees. The distribution fees, based on contractually determined rates, arise from contractual agreements 
we have with certain wholesalers for distribution services they provide with respect to Hylenex recombinant. These 
fees are generally a fixed percentage of the price of the product purchased by the wholesalers. 

F-11

Halozyme Therapeutics, Inc.

Notes to Consolidated Financial Statements — (Continued)

•  Prompt Payment Discounts. We offer cash discounts to certain wholesalers as an incentive to meet certain payment 
terms. We estimate prompt payment discounts based on contractual terms, historical utilization rates, as available, 
and our expectations regarding future utilization rates. 

•  Other Discounts and Fees. We provide discounts to end-user members of certain GPOs under collective purchasing 
contracts between us and the GPOs. We also provide discounts to certain hospitals, who are members of the GPOs, 
with which we do not have contracts. The end-user members purchase products from the wholesalers at a contracted 
discounted price, and the wholesalers then charge back to us the difference between the current retail price and the 
price the end-users paid for the product. We also incur GPO administrative service fees for these transactions. In 
addition, we provide predetermined discounts under certain government programs. Our estimate for these chargebacks 
and fees takes into consideration contractual terms, historical utilization rates, as available, and our expectations 
regarding future utilization rates.

Allowances for product returns and chargebacks are based on amounts owed or to be claimed on the related sales. We believe 
that our estimated product returns for Hylenex recombinant requires the use of judgment and is subject to change based on our 
experience and certain quantitative and qualitative factors. In order to develop a methodology to reliably estimate future returns 
and  provide  a  basis  for  recognizing  revenue  on  sales  to  wholesale  distributors,  we  analyze  many  factors,  including,  without 
limitation: (1) actual Hylenex recombinant product return history, taking into account product expiration dating at the time of 
shipment, (2) re-order activities of the wholesalers as well as their customers and (3) levels of inventory in the wholesale channel. 
We have monitored actual return history on an individual product lot basis since product launch. We consider the dating of product 
at the time of shipment into the distribution channel and changes in the estimated levels of inventory within the distribution channel 
to estimate our exposure to returned product. We also consider historical chargebacks activity and current contract prices to estimate 
our exposure to returned product. Based on such data, we believe we have the information needed to reasonably estimate product 
returns and chargebacks. 

We recognize product sales reserves and allowances as a reduction of product sales in the same period the related revenue 
is recognized. Because of the shelf life of Hylenex recombinant and our lengthy return period, there may be a significant period 
of time between when the product is shipped and when we issue credits on returned product. If actual product return results differ 
from our estimates, we will be required to make adjustments to these allowances in the future, which could have an effect on 
product sales revenue and earnings in the period of adjustments. 

Bulk rHuPH20

Subsequent to receiving marketing approval from the FDA or comparable regulatory agencies in foreign countries, sales of 
bulk rHuPH20 for use in collaboration commercial products are recognized as product sales when the materials have met all the 
specifications required for the customer’s acceptance and title and risk of loss have transferred to the customer. Following the 
receipt of European marketing approvals of Roche’s Herceptin SC product in August 2013 and MabThera® SC product in March 
2014 and Baxalta’s HYQVIA product in May 2013, revenue from the sales of bulk rHuPH20 for these collaboration products has 
been recognized as product sales.

Revenues under Collaborative Agreements 

We have entered into license and collaboration agreements under which our collaborators obtained worldwide rights for the 
use of our proprietary rHuPH20 enzyme in the development and commercialization of their biologic compounds identified as 
targets. These agreements may also contain other elements. Pursuant to the terms of these agreements, collaborators could be 
required to make various payments to us for each target, including nonrefundable upfront license fees, exclusivity fees, payments 
based on achievement of specified milestones designated in the collaborative agreements, annual maintenance fees, reimbursements 
of research and development services, payments for supply of bulk rHuPH20 used by the collaborator and/or royalties on sales of 
products resulting from collaborative agreements. 

In order to account for the multiple-element arrangements, we identify the deliverables included within the collaborative 
agreement and evaluate which deliverables represent units of accounting. We then determine the appropriate method of revenue 
recognition for each unit based on the nature and timing of the delivery process. Analyzing the arrangement to identify deliverables 
requires the use of judgment, and each deliverable may be an obligation to deliver services, a right or license to use an asset, or 
another  performance  obligation. The  deliverables  under  our  collaborative  agreements  include  (i) the  license  to  our  rHuPH20 
technology, (ii) at the collaborator’s request, research and development services which are reimbursed at contractually determined 
rates, and (iii) at the collaborator’s request, supply of bulk rHuPH20 which is reimbursed at our cost plus a margin. A delivered 
item is considered a separate unit of accounting when the delivered item has value to the collaborator on a standalone basis based 
on the consideration of the relevant facts and circumstances for each arrangement. We base this determination on the collaborators’ 

F-12

Halozyme Therapeutics, Inc.

Notes to Consolidated Financial Statements — (Continued)

ability to use the delivered items on their own without us supplying undelivered items, which we determine taking into consideration 
factors  such  as  the  research  capabilities  of  the  collaborator,  the  availability  of  research  expertise  in  this  field  in  the  general 
marketplace, and the ability to procure the supply of bulk rHuPH20 from the marketplace. 

Arrangement consideration is allocated at the inception of the agreement to all identified units of accounting based on their 
relative selling price. The relative selling price for each deliverable is determined using vendor specific objective evidence (“VSOE”) 
of selling price or third-party evidence of selling price if VSOE does not exist. If neither VSOE nor third-party evidence of selling 
price exists, we use our best estimate of the selling price for the deliverable. The amount of allocable arrangement consideration 
is limited to amounts that are not contingent upon the delivery of additional items or meeting other specified performance conditions. 
The consideration received is allocated among the separate units of accounting and the applicable revenue recognition criteria are 
applied to each of the separate units. Changes in the allocation of the sales price between delivered and undelivered elements can 
impact revenue recognition but do not change the total revenue recognized under any agreement.

Nonrefundable upfront license fees are recognized upon delivery of the license if facts and circumstances dictate that the 
license has standalone value from the undelivered items, which generally include research and development services and the 
manufacture of bulk rHuPH20, the relative selling price allocation of the license is equal to or exceeds the upfront license fee, 
persuasive evidence of an arrangement exists, our price to the collaborator is fixed or determinable and collectibility is reasonably 
assured. Upfront license fees are deferred if facts and circumstances dictate that the license does not have standalone value. The 
determination of the length of the period over which to defer revenue is subject to judgment and estimation and can have an impact 
on the amount of revenue recognized in a given period.

When collaborators have rights to elect additional targets, the rights are assessed as to whether they represent deliverables 
at the inception of the arrangement. In assessing these contingent deliverables, we consider whether the right is a substantive 
option. We consider a right to be a substantive option if the election of the additional targets is not essential to the functionality of 
the other elements in the arrangement and if we are truly at risk of the right being exercised. If the right is determined to be a 
substantive option, we further consider whether the right is priced at a significant and incremental discount that should be accounted 
for as an element of the arrangement. If a right is determined to be a substantive option and is not priced at a significant and 
incremental discount, it is not treated as a deliverable in the arrangement and receives no allocation at the inception of the arrangement 
of the original arrangement consideration. The right is then accounted for when and if it is exercised.

Certain of our collaborative agreements provide for milestone payments upon achievement of development and regulatory 
events and/or specified sales volumes of commercialized products by the collaborator. We account for milestone payments in 
accordance  with  the  provisions  of  ASU  No.  2010-17,  Revenue  Recognition  -  Milestone  Method  (“Milestone  Method  of 
Accounting”). We recognize consideration that is contingent upon the achievement of a milestone in its entirety as revenue in the 
period in which the milestone is achieved only if the milestone is substantive in its entirety. A milestone is considered substantive 
when it meets all of the following criteria:

1.  The consideration is commensurate with either the entity’s performance to achieve the milestone or the enhancement 
of the value of the delivered item(s) as a result of a specific outcome resulting from the entity’s performance to achieve 
the milestone;

2.  The consideration relates solely to past performance; and

3.  The consideration is reasonable relative to all of the deliverables and payment terms within the arrangement.

A milestone is defined as an event (i) that can only be achieved based in whole or in part on either the entity’s performance 
or on the occurrence of a specific outcome resulting from the entity’s performance, (ii) for which there is substantive uncertainty 
at the date the arrangement is entered into that the event will be achieved, and (iii) that would result in additional payments being 
due to the vendor.

Reimbursements of research and development services are recognized as revenue during the period in which the services 
are performed as long as there is persuasive evidence of an arrangement, the fee is fixed or determinable and collection of the 
related receivable is reasonably assured. Revenue from the manufacture of bulk rHuPH20 is recognized when the materials have 
met all specifications required for the collaborator’s acceptance and title and risk of loss have transferred to the collaborator. We 
do not directly control when any collaborator will request research and development services or supply of bulk rHuPH20; therefore, 
we cannot predict when we will recognize revenues in connection with research and development services and supply of bulk 
rHuPH20. 

Since we receive royalty reports 60 days after quarter end, royalty revenue from sales of collaboration products by our 

collaborators is recognized in the quarter following the quarter in which the corresponding sales occurred.

F-13

Halozyme Therapeutics, Inc.

Notes to Consolidated Financial Statements — (Continued)

The collaborative agreements typically provide the collaborators the right to terminate such agreement in whole or on a 
product-by-product or target-by-target basis at any time upon 30 to 90 days prior written notice to us. There are no performance, 
cancellation, termination or refund provisions in any of our collaborative agreements that contain material financial consequences 
to us.

Refer to Note 4, “Collaborative Agreements,” for further discussion on our collaborative arrangements.

Cost of Product Sales

Cost of product sales consists primarily of raw materials, third-party manufacturing costs, fill and finish costs, freight costs, 
internal costs and manufacturing overhead associated with the production of Hylenex recombinant and bulk rHuPH20 for use in 
approved collaboration products. Cost of product sales also consists of the write-down of excess, dated and obsolete inventories 
and the write-off of inventories that do not meet certain product specifications, if any.

Prior to European marketing approvals of Roche’s collaboration products Herceptin SC in August 2013 and MabThera SC 
in March 2014 and Baxalta’s collaboration product HYQVIA in May 2013, all costs related to the manufacturing of bulk rHuPH20 
for these collaboration products were charged to research and development expenses in the periods such costs were incurred. For 
the year ended December 31, 2014, cost of product sales of bulk rHuPH20 excluded $1.0 million in manufacturing costs, of which 
$0.9 million and $0.1 million were charged to research and development expenses in the years ended December 31, 2013 and 
2012, respectively. There was no bulk rHuPH20 excluded from cost of product sales for the years ended December 31, 2016 and 
2015.

Research and Development Expenses

Research and development expenses include salaries and benefits, facilities and other overhead expenses, external clinical 
trial expenses, research related manufacturing services, contract services and other outside expenses. Research and development 
expenses are charged to operating expenses as incurred when these expenditures relate to our research and development efforts 
and have no alternative future uses. After receiving approval from the FDA or comparable regulatory agencies in foreign countries 
for a product, costs related to purchases and manufacturing of bulk rHuPH20 for such product are capitalized as inventory. The 
manufacturing costs of bulk rHuPH20 for the collaboration products, Herceptin SC, MabThera SC and HYQVIA, incurred after 
the receipt of marketing approvals are capitalized as inventory.

We  are  obligated  to  make  upfront  payments  upon  execution  of  certain  research  and  development  agreements. Advance 
payments, including nonrefundable amounts, for goods or services that will be used or rendered for future research and development 
activities are deferred. Such amounts are recognized as expense as the related goods are delivered or the related services are 
performed or such time when we do not expect the goods to be delivered or services to be performed.

Milestone payments that we make in connection with in-licensed technology for a particular research and development 
project that have no alternative future uses (in other research and development projects or otherwise) and therefore no separate 
economic value are expensed as research and development costs at the time the costs are incurred. We currently have no in-licensed 
technologies that have alternative future uses in research and development projects or otherwise.

Clinical Trial Expenses

Payments in connection with our clinical trials are often made under contracts with multiple contract research organizations 
that conduct and manage clinical trials on our behalf. The financial terms of these agreements are subject to negotiation and vary 
from contract to contract and may result in uneven payment flows. Generally, these agreements set forth the scope of work to be 
performed at a fixed fee, unit price or on a time and materials basis. A portion of our obligation to make payments under these 
contracts depends on factors such as the successful enrollment or treatment of patients or the completion of other clinical trial 
milestones. 

Expenses related to clinical trials are accrued based on our estimates and/or representations from service providers regarding 
work performed, including actual level of patient enrollment, completion of patient studies and progress of the clinical trials. Other 
incidental costs related to patient enrollment or treatment are accrued when reasonably certain. If the amounts we are obligated to 
pay under our clinical trial agreements are modified (for instance, as a result of changes in the clinical trial protocol or scope of 
work to be performed), we adjust our accruals accordingly on a prospective basis. Revisions to our contractual payment obligations 
are charged to expense in the period in which the facts that give rise to the revision become reasonably certain. Historically, such 
revisions to our clinical trial expense accruals have not had a material impact on our consolidated results of operations or financial 
position.

Share-Based Compensation

We record compensation expense associated with stock options, restricted stock awards (“RSAs”), restricted stock units 
(“RSUs”),  and  RSUs  with  performance  conditions  (“PRSUs”)  in  accordance  with  the  authoritative  guidance  for  stock-based 
compensation. The cost of employee services received in exchange for an award of an equity instrument is measured at the grant 
date, based on the estimated fair value of the award, and is recognized as expense on a straight-line basis over the requisite service 
period  of  the  award.  Share-based  compensation  expense  for  an  award  with  a  performance  condition  is  recognized  when  the 
achievement of such performance condition is determined to be probable. If the outcome of such performance condition is not 
determined to be probable or is not met, no compensation expense is recognized and any previously recognized compensation 
expense is reversed. Forfeitures are recognized as a reduction of share-based compensation expense as they occur.

Income Taxes

We provide for income taxes using the liability method. Under this method, deferred income tax assets and liabilities are 
determined based on the differences between the financial statement carrying amounts of existing assets and liabilities at each year 
end and their respective tax bases and are measured using enacted tax rates in effect for the year in which the differences are 
expected to affect taxable income. Significant judgment is required by management to determine our provision for income taxes, 
our deferred tax assets and liabilities, and the valuation allowance to record against our net deferred tax assets, which are based 
on complex and evolving tax regulations throughout the world. Deferred tax assets and other tax benefits are recorded when it is 
more likely than not that the position will be sustained upon audit. While we have begun to utilize certain of our net operating 
losses, we have not yet established a track record of profitability. Accordingly, valuation allowances have been recorded to reduce 
our net deferred tax assets to zero until such time we can demonstrate an ability to realize them.

During  the  fourth  quarter  of  2016,  we  established  a  new  Swiss  subsidiary,  Halozyme  Switzerland  GmbH  (Halozyme 
Switzerland). Halozyme Switzerland is party to a tax ruling providing that the total Swiss income tax rate will not exceed 10% 
through December 2026.

Net Loss Per Share

Basic net loss per common share is computed by dividing net loss for the period by the weighted average number of common 
shares outstanding during the period, without consideration for common stock equivalents. Outstanding stock options, unvested 
RSAs, unvested RSUs and unvested PRSUs are considered common stock equivalents and are only included in the calculation of 
diluted earnings per common share when net income is reported and their effect is dilutive. Because of our net loss, outstanding 
common stock equivalents totaling approximately 13,761,123, 9,780,593 and 8,405,903 were excluded from the calculation of 
diluted net loss per common share for the years ended December 31, 2016, 2015 and 2014, respectively, because their effect was 
anti-dilutive.

Segment Information

We  operate  our  business  in  one  segment,  which  includes  all  activities  related  to  the  research,  development  and 
commercialization  of  our  proprietary  enzymes. This  segment  also  includes  revenues  and  expenses  related  to  (i) research  and 
development and bulk rHuPH20 manufacturing activities conducted under our collaborative agreements with third parties and 
(ii) product sales of Hylenex recombinant. The chief operating decision-maker reviews the operating results on an aggregate basis 
and manages the operations as a single operating segment. Our long-lived assets located in foreign countries had minimal book 
value as of December 31, 2016 and 2015. 

Adoption and Pending Adoption of Recent Accounting Pronouncements

The following table provides a brief description of recently issued accounting standards, those adopted in the current year 

and those not yet adopted:

Standard

Description

In April 2015, the Financial
Accounting Standards Board
(“FASB”) issued Accounting
Standards Update (“ASU”)
2015-03, Interest - Imputation of
Interest (Subtopic 835-30):
Simplifying the Presentation of
Debt Issuance Costs.

In November 2015, the FASB
issued ASU 2015-17, Balance
Sheet Classification of Deferred
Taxes.

In March 2016, the FASB issued
ASU 2016-09, Compensation -
Stock Compensation.

In August 2014, the FASB issued
ASU 2014-15, Presentation of
Financial Statements — Going
Concern.

The new guidance requires that debt
issuance costs related to a recognized
debt liability be presented in the
balance sheet as a direct deduction
from that debt liability, consistent with
the presentation of a debt discount.

The new guidance requires companies
to classify all deferred tax assets and
liabilities as non-current on the
balance sheet instead of separating
deferred taxes into current and non-
current amounts.

The new guidance changes certain
aspects of accounting for share-based
payments to employees and involves
several aspects of the accounting for
share-based payment transactions,
including the income tax
consequences, classification of awards
as either equity or liabilities, and
classification on the statement of cash
flows. Specifically, the new guidance
requires that all income tax effects of
share-based awards be recognized as
income tax expense or benefit in the
reporting period in which they occur.
Additionally, the new guidance
amends existing guidance to allow
forfeitures of share-based awards to be
recognized as they occur.

The new guidance requires, in
connection with preparing financial
statements for each annual and interim
reporting period, an entity’s
management to evaluate whether there
are conditions or events, considered in
the aggregate, that raise substantial
doubt about the entity’s ability to
continue as a going concern within one
year after the date that the financial
statements are issued (or within one
year after the date that the financial
statements are available to be issued
when applicable).

Effect on the Financial 
Statements or Other Significant 
Matters

In July 2015, the FASB issued
ASU 2015-11, Inventory:
Simplifying the Measurement of
Inventory.

In January 2016, the FASB issued
ASU 2016-01, Financial
Instruments - Overall; Recognition
and Measurement of Financial
Assets and Financial Liabilities.

The new guidance requires that for
entities that measure inventory using
the first-in, first-out method, inventory
should be measured at the lower of
cost or net realizable value. Topic 330,
Inventory, currently requires an entity
to measure inventory at the lower of
cost or market. Market could be
replacement cost, net realizable value,
or net realizable value less an
approximate normal profit margin. Net
realizable value is the estimated selling
price in the ordinary course of
business, less reasonably predictable
costs of completion, disposal, and
transportation.

The new guidance supersedes the
guidance to classify equity securities
with readily determinable fair values
into different categories (that is,
trading or available-for-sale) and
requires equity securities to be
measured at fair value with changes in
the fair value recognized through net
income. The new guidance requires
public business entities that are
required to disclose fair value of
financial instruments measured at
amortized cost on the balance sheet to
measure that fair value using the exit
price notion consistent with Topic 820,
Fair Value Measurement.

January 1, 2017. The adoption is not

expected to have a material
impact on our consolidated
financial position or results
of operations.

January 1, 2018. We currently do not hold

Standard

Description

In May 2014, the FASB issued
ASU 2014-09, Revenue from
Contracts with Customers (Topic
606). In March, April, May and
December 2016, the FASB issued
additional guidance related to
Topic 606.

In August 2016, the FASB issued 
ASU 2016-15, Statement of Cash 
Flows: Classification of Certain 
Cash Receipts and Cash Payments.

In November 2016, the FASB 
issued ASU 2016-18, Statement of 
Cash Flows: Restricted Cash. 

The new standard will supersede 
nearly all existing revenue recognition 
guidance. Under Topic 606, an entity 
is required to recognize revenue upon 
transfer of promised goods or services 
to customers in an amount that reflects 
the expected consideration to be 
received in exchange for those goods 
or services. Topic 606 defines a five-
step process in order to achieve this 
core principle, which may require the 
use of judgment and estimates, and 
also requires expanded qualitative and 
quantitative disclosures relating to the 
nature, amount, timing and uncertainty 
of revenue and cash flows arising from 
contracts with customers, including 
significant judgments and estimates 
used. The new standard also defines 
accounting for certain costs related to 
origination and fulfillment of contracts 
with customers, including whether 
such costs should be capitalized. The 
new standard permits adoption either 
by using (i) a full retrospective 
approach for all periods presented in 
the period of adoption or (ii) a 
modified retrospective approach where 
the new standard is applied in the 
financial statements starting with the 
year of adoption. Under both 
approaches, cumulative impact of the 
adoption is reflected as an adjustment 
to retained earnings (accumulated 
deficit) as of the earliest date presented 
in accordance with the new standard.

Current U.S. GAAP either is unclear
or does not include specific guidance
on the eight cash flow classification
issues included in ASU 2016-15. The
new guidance is an improvement to
U.S. GAAP and is intended to reduce
the current and potential future
diversity in practice. ASU 2016-18
provides additional classification
guidance for restricted cash, which
requires that restricted cash be
included with cash and cash
equivalents when reconciling the
beginning-of-period and end-of-period
total amounts shown on the statement
of cash flows.

_______________

(1)  Under  the  new  standard,  we  are  required  to  assess  whether  licenses  granted  under  our  collaboration  and  license 
agreements are distinct from other performance obligations and functional when granted. We expect that license-related 
amounts, including upfront payments, exclusive designation fees, annual license maintenance fees and sales based 
milestones will be recognized, generally, when earned. Currently, these amounts as related to certain of our license and 
collaboration agreements are being amortized over the term of the collaboration agreement. For example, during the 
year ended December 31, 2016 we recognized revenue from amortization of license payments of $4.1 million, and total 
deferred  revenue  related  to  license  payments  under  collaboration  agreements  as  of  December  31,  2016  was  $43.9 
million. While we have not completed our evaluation at this time, we anticipate a potential reduction or elimination of 
our associated deferred revenue balances upon adoption of Topic 606.

(2)  Under the new standard, we expect sales-based royalties will be recognized in the quarter they are earned based on 
estimates, with true-up to actual results following the in the subsequent quarter. Sales-based royalty revenue earned 
under our collaboration and license agreements is presently recognized when the royalty reports are made available. 
Upon adoption of Topic 606, we will evaluate and reduce our accumulated deficit, and increase our accounts receivable, 
net,  by  the  amount  earned  but  not  yet  reported  in  our  consolidated  balance  sheet  at  the  time  of  adoption. We  are 
establishing a process to estimate sales-based royalty revenues in the quarter in which the sales occur.

Notes to Consolidated Financial Statements — (Continued)

As of December 31, 2016, $132.2 million of our available-for-sale marketable securities were scheduled to mature within 
the next twelve months. There were $81.8 million of available-for-sale securities that matured during the year ended December 31, 
2016. There were no realized gains or losses for the years ended December 31, 2016, 2015 and 2014. As of December 31, 2016, 
11 available-for-sale marketable securities were in a gross unrealized loss position, all of which had been in such position for less 
than twelve months. Based on our review of these marketable securities, we believe we had no other-than-temporary impairments 
on these securities as of December 31, 2016 because we do not intend to sell these securities and it is not more-likely-than-not 
that we will be required to sell these securities before the recovery of their amortized cost basis.

4.  Collaborative Agreements

Roche Collaboration

In December 2006, we and Roche entered into a collaboration and license agreement, under which Roche obtained a worldwide 
license to develop and commercialize product combinations of rHuPH20 and up to thirteen Roche target compounds (the “Roche 
Collaboration”). Roche initially had the exclusive right to apply rHuPH20 to three pre-defined Roche biologic targets with the 
option to develop and commercialize rHuPH20 with ten additional targets. Roche had the right to exercise this option to identify 
additional targets for ten years. As of the ten year anniversary in December 2016, Roche has elected a total of eight targets, two
of which are exclusive. 

In August 2013, Roche received European marketing approval for its collaboration product, Herceptin SC, for the treatment 
of patients with HER2-positive breast cancer and launched Herceptin SC in the European Union (“EU”) in September 2013. In 
March 2014, Roche received European marketing approval for its collaboration product, MabThera SC, for the treatment of patients 
with common forms of non-Hodgkin lymphoma (“NHL”). In June 2014, Roche launched MabThera SC in the EU. In May 2016, 
Roche announced that the EMA approved Mabthera SC to treat patients with chronic lymphocytic leukemia. In November 2016, 
the  FDA  accepted  Genentech’s  (a  member  of  the  Roche  Group)  Biologics  License Application  (“BLA”)  for  a  subcutaneous 
formulation of rituximab for CLL and NHL. This is a co-formulation with rHuPH20, which is approved and marketed under the 
MabThera SC brand in countries outside the U.S.

Roche assumes all development, manufacturing, clinical, regulatory, sales and marketing costs under the Roche Collaboration, 
while we are responsible for the supply of bulk rHuPH20. We are entitled to receive reimbursements for providing research and 
development services and supplying bulk rHuPH20 to Roche at its request.

Under the terms of the Roche Collaboration, Roche pays us a royalty on each product commercialized under the agreement 
consisting of a mid-single digit percent of the net sales of such product. Unless terminated earlier in accordance with its terms, 
the Roche Collaboration continues in effect until the expiration of Roche’s obligation to pay royalties. Roche has the obligation 
to pay royalties to us with respect to each product commercialized in each country, during the period equal to the longer of: (a) 
the duration of any valid claim of our patents covering rHuPH20 or other specified patents developed under the Roche Collaboration 
which valid claim covers the product in such country or (b) ten years following the date of the first commercial sale of such product 
in such country. In the event such valid claims expire, the royalty rate is reduced for the remaining royalty term.

Payments received from Roche, excluding royalties and reimbursements for providing research and development services 

and supplying bulk rHuPH20, since inception of the collaboration agreement are as follows (in thousands):

Upfront license fee payment for the application of rHuPH20 to the initial exclusive targets . . . . . . . . . . $
Election of additional exclusive targets and annual license maintenance fees for the right to 
   designate the remaining targets as exclusive targets. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Due to our continuing involvement obligations (for example, support activities associated with rHuPH20), revenues from 
the upfront payment, exclusive designation fees, annual license maintenance fees and sales-based milestone payments were deferred 
and are being amortized over the remaining term of the Roche Collaboration.

Notes to Consolidated Financial Statements — (Continued)

For the years ended December 31, 2016, 2015 and 2014, we recognized approximately $3.3 million, $3.3 million, and $3.0 
million, respectively, of Roche deferred revenues, excluding reimbursements for providing research and development services and 
supplying bulk rHuPH20, as revenues under collaborative agreements. Total Roche deferred revenues, excluding deferred revenues 
related to reimbursements for providing research and development services and supplying bulk rHuPH20, were approximately 
$35.7 million and $39.0 million as of December 31, 2016 and 2015, respectively. 

Baxalta Collaboration

In September 2007, we and Baxalta entered into a collaboration and license agreement, under which Baxalta obtained a 
worldwide, exclusive license to develop and commercialize HYQVIA, a combination of Baxalta’s current product GAMMAGARD 
LIQUID™ and our patented rHuPH20 enzyme (the “Baxalta Collaboration”). In May 2013, the European Commission granted 
Baxalta marketing authorization in all EU Member States for the use of HYQVIA (solution for subcutaneous use), a combination 
of GAMMAGARD LIQUID and rHuPH20 in dual vial units, as replacement therapy for adult patients with primary and secondary 
immunodeficiencies. Baxalta launched HYQVIA in the EU in July 2013. In September 2014, the FDA approved HYQVIA for 
treatment of adult patients with primary immunodeficiency. In October 2014, Baxalta announced the launch and first shipments 
of HYQVIA in the U.S. 

The  Baxalta  Collaboration  is  applicable  to  both  kit  and  formulation  combinations.  Baxalta  assumes  all  development, 
manufacturing, clinical, regulatory, sales and marketing costs under the Baxalta Collaboration, while we are responsible for the 
supply of bulk rHuPH20. We perform research and development activities and supply bulk rHuPH20 at the request of Baxalta, 
and are reimbursed by Baxalta under the terms of the Baxalta Collaboration. In addition, Baxalta has certain product development 
and commercialization obligations in major markets identified in the Baxalta Collaboration.

Under the terms of the Baxalta Collaboration, Baxalta pays us a royalty consisting of a mid-single digit percent of the net 
sales of HYQVIA. Unless terminated earlier in accordance with its terms, the Baxalta Collaboration continues in effect until the 
expiration of Baxalta’s obligation to pay royalties to us. Baxalta has the obligation to pay royalties to us, with respect to each 
product commercialized in each country, during the period equal to the longer of: (a) the duration of any valid claim of our patents 
covering rHuPH20 or other specified patents developed under the Baxalta Collaboration which valid claim covers the product in 
such country or (b) ten years following the date of the first commercial sale of such product in such country. In the event such 
valid claims expire, the royalty rate is reduced for the remaining royalty term.

Payments received from Baxalta, excluding royalties and reimbursements for providing research and development services 

and supplying bulk rHuPH20, since inception of the collaboration agreement are as follows (in thousands):

Upfront license fee payment for the application of rHuPH20 to the initial exclusive target. . . . . . . . . . . $
Regulatory milestone payments. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Total payments received . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $

As of 
December 31, 2016
10,000
3,000

17,000

Due to our continuing involvement obligations (for example, support activities associated with rHuPH20 enzyme), the upfront 
license fee and sales-based milestone payments were deferred and are being recognized over the term of the Baxalta Collaboration. 

For each of the years ended December 31, 2016, 2015 and 2014, we recognized approximately $0.8 million of Baxalta 
deferred revenues as revenues under collaborative agreements. Total Baxalta deferred revenues were approximately $8.2 million
and $9.0 million as of December 31, 2016 and 2015, respectively.

Other Collaborations

In December 2015, we and Lilly entered into a collaboration and license agreement, under which Lilly has the worldwide 
license to develop and commercialize products combining our patented rHuPH20 enzyme with Lilly proprietary biologics directed 
at up to five targets (the “Lilly Collaboration”). Targets, once selected, will be on an exclusive, global basis. As of December 31, 
2016, Lilly has elected two specified exclusive targets and one specified semi-exclusive target. Lilly has the right to elect up to 
two additional targets for additional fees. The upfront license payment may be followed by event-based payments subject to Lilly’s 
achievement of specified development, regulatory and sales-based milestones. In addition, Lilly will pay royalties to us if products 
under the collaboration are commercialized. Unless terminated earlier in accordance with its terms, the Lilly Collaboration continues 
in effect until the later of: (i) expiration of the last to expire of the valid claims of our patents covering rHuPH20 or other specified 
patents developed under the collaboration which valid claim covers a product developed under the collaboration, and (ii) expiration 
of the last to expire royalty term for a product developed under the collaboration. The royalty term of a product developed under 
the Lilly Collaboration, with respect to each country, consists of the period equal to the longer of: (a) the duration of any valid 
claim of our patents covering rHuPH20 or other specified patents developed under the collaboration which valid claim covers the 
product in such country or (b) ten years following the date of the first commercial sale of such product in such country. In the 
event such valid claims expire, the royalty rate is reduced for the remaining royalty term. Lilly may terminate the agreement prior 
to expiration for any reason in its entirety upon 60 days prior written notice to us. Upon any such termination, the license granted 
to Lilly (in total or with respect to the terminated target, as applicable) will terminate provided, however, that in the event of 
expiration of the agreement, the licenses granted will become perpetual, non-exclusive and fully paid.

In June 2015, we and AbbVie entered into a collaboration and license agreement, under which AbbVie has the worldwide 
license  to  develop  and  commercialize  products  combining  our  patented  rHuPH20  enzyme  with AbbVie  proprietary  biologics 
directed at up to nine targets (the “AbbVie Collaboration”). Targets, once selected, will be on an exclusive, global basis. As of 
December 31,  2016, AbbVie  has  elected  one  specified  exclusive  target, TNF  alpha. AbbVie  has  the  right  to  elect  up  to  eight
additional targets for additional fees. The upfront license payment may be followed by event-based payments subject to AbbVie’s 
achievement of specified development, regulatory and sales-based milestones. In addition, AbbVie will pay tiered royalties to us 
if  products  under  the  collaboration  are  commercialized.  Unless  terminated  earlier  in  accordance  with  its  terms,  the AbbVie 
Collaboration continues in effect until the later of: (i) expiration of the last to expire of the valid claims of our patents covering 
rHuPH20 or other specified patents developed under the collaboration which valid claim covers a product developed under the 
collaboration, and (ii) expiration of the last to expire royalty term for a product developed under the collaboration. The royalty 
term of a product developed under the AbbVie Collaboration, with respect to each country, consists of the period equal to the 
longer of: (a) the duration of any valid claim of our patents covering rHuPH20 or other specified patents developed under the 
collaboration which valid claim covers the product in such country or (b) ten years following the date of the first commercial sale 
of such product in such country. In the event such valid claims expire, the royalty rate is reduced for the remaining royalty term. 
AbbVie may terminate the agreement prior to expiration for any reason in its entirety or on a target-by-target basis upon 90 days
prior written notice to us. Upon any such termination, the license granted to AbbVie (in total or with respect to the terminated 
target, as applicable) will terminate provided, however, that in the event of expiration of the agreement, the licenses granted will 
become perpetual, non-exclusive and fully paid.

In December 2014, we and Janssen entered into a collaboration and license agreement, under which Janssen has the worldwide 
license  to  develop  and  commercialize  products  combining  our  patented  rHuPH20  enzyme  with  Janssen  proprietary  biologics 
directed at up to five targets (the “Janssen Collaboration”). Targets, once selected, will be on an exclusive, global basis. As of 
December 31, 2016, Janssen has elected one specified exclusive target, CD38. Janssen has the right to elect four additional targets 
in the future upon payment of additional fees. In addition, Janssen will pay royalties to us if products under the collaboration are 
commercialized. Unless terminated earlier in accordance with its terms, the Janssen Collaboration continues in effect until the 
later of (i) expiration of the last to expire of the valid claims of our patents covering rHuPH20 or other specified patents developed 
under the collaboration which valid claim covers a product developed under the collaboration, and (ii) expiration of the last to 
expire royalty term for a product developed under the collaboration. The royalty term of a product developed under the Janssen 
Collaboration, with respect to each country, consists of the period equal to the longer of: (a) the duration of any valid claim of our 
patents covering rHuPH20 or other specified patents developed under the collaboration which valid claim covers the product in 
such country or (b) ten years following the date of the first commercial sale of such product in such country. In the event such 
valid claims expire, the royalty rate is reduced for the remaining royalty term. Janssen may terminate the agreement prior to 
expiration for any reason in its entirety or on a product-by-product basis upon 90 days prior written notice to us. Upon any such 
termination, the license granted to Janssen (in total or with respect to the terminated target, as applicable) will terminate provided, 
however, that in the event of expiration of the agreement, the licenses granted will become perpetual, non-exclusive and fully paid.

In December 2012, we and Pfizer entered into a collaboration and license agreement, under which Pfizer has the worldwide 
license to develop and commercialize products combining our patented rHuPH20 enzyme with Pfizer proprietary biologics directed 
at up to six targets (the “Pfizer Collaboration”). Targets may be selected on an exclusive or non-exclusive basis. As of December 31, 
2016, Pfizer has elected five specified exclusive targets. In December 2016, Pfizer returned one of its elected targets. Pfizer has 
the right to elect two additional targets in the future upon payment of additional fees. In addition, Pfizer will pay royalties to us if 
products under the collaboration are commercialized. Unless terminated earlier in accordance with its terms, the Pfizer Collaboration 
continues in effect until the later of (i) expiration of the last to expire of the valid claims of our patents covering rHuPH20 or other 
specified patents developed under the collaboration which valid claim covers a product developed under the collaboration, and 
(ii) expiration of the last to expire royalty term for a product developed under the collaboration. The royalty term of a product 
developed under the Pfizer Collaboration, with respect to each country, consists of the period equal to the longer of: (a) the duration 
of any valid claim of our patents covering rHuPH20 or other specified patents developed under the collaboration which valid claim 
covers the product in such country or (b) ten years following the date of the first commercial sale of such product in such country. 
Royalties are subject to adjustment as set forth in the agreement. Pfizer may terminate the agreement prior to expiration for any 
reason in its entirety or on a target-by-target basis upon 30 days prior written notice to us. Upon any such termination, the license 
granted to Pfizer (in total or with respect to the terminated target, as applicable) will terminate, provided, however, that in the event 
of expiration of the agreement, the licenses granted will become perpetual, non-exclusive and fully paid.

At the inception of the Pfizer, Janssen, AbbVie and Lilly arrangements, we identified the deliverables in each arrangement 
to include the license, research and development services and supply of bulk rHuPH20. We have determined that the license, 
research and development services and supply of bulk rHuPH20 individually represent separate units of accounting, because each 
deliverable has standalone value. We determined that the rights to elect additional targets in the future upon the payment of additional 
license fees are substantive options that are not priced at a significant and incremental discount. Therefore, we determined for each 
collaboration that the rights to elect additional targets are not deliverables at the inception of the arrangement. The estimated selling 
prices for the units of accounting we identified were determined based on market conditions, the terms of comparable collaborative 
arrangements for similar technology in the pharmaceutical and biotech industry and entity-specific factors such as the terms of 
our previous collaborative agreements, our pricing practices and pricing objectives. The arrangement consideration was allocated 
to the deliverables based on the relative selling price method and the nature of the research and development services to be performed 
for the collaborator. 

The amount allocable to the delivered unit or units of accounting is limited to the amount that is not contingent upon the 
delivery of additional items or meeting other specified performance conditions (non-contingent amount). As such, we excluded 
from the allocable arrangement consideration the event-based payments, milestone payments, annual exclusivity fees and royalties 
regardless of the probability of receipt. Based on the results of our analysis, we allocated the $12.5 million license fees from Pfizer, 
the $15.3 million license fee from Janssen, the $23.0 million upfront license fee from AbbVie and the $33.0 million license fees 
from Lilly to the license fee deliverable under each of the arrangements. We determined that the upfront payments were earned 
upon the granting of the worldwide, exclusive right to our technology to the collaborators in these arrangements. As a result, we 
recognized  the  $12.5  million  license  fees  under  the  Pfizer  Collaboration,  the  $15.3  million  license  fee  under  the  Janssen 
Collaboration, the $23.0 million upfront license fee under the AbbVie Collaboration and the $33.0 million license fees under the 
Lilly Collaboration as revenues under collaborative agreements in the period when such license fees were earned. We recognized 
revenue related to event-based payments or milestone payments under these collaborations of $6.0 million, $1.0 million and zero
for the years ended December 31, 2016, 2015 and 2014, respectively.

The collaborators are each solely responsible for the development, manufacturing and marketing of any products resulting 
from their respective collaborations. We are entitled to receive payments for research and development services and supply of bulk 
rHuPH20 if requested by any collaborator. We recognize amounts allocated to research and development services as revenues 
under collaborative agreements as the related services are performed. We recognize amounts allocated to the sales of bulk rHuPH20 
as  revenues  under  collaborative  agreements  or  product  sales,  as  appropriate,  when  such  bulk  rHuPH20  has  met  all  required 
specifications by the collaborators and the related title and risk of loss and damages have passed to the collaborators. We cannot 
predict the timing of delivery of research and development services and bulk rHuPH20 as they are at the collaborators’ requests.

Pursuant to the terms of our collaboration agreements with Roche and Pfizer, certain future payments meet the definition of 
a milestone in accordance with the Milestone Method of Accounting. We are entitled to receive additional milestone payments 
under our collaboration agreements with Roche and Pfizer for the successful development of the elected targets in the aggregate 
of  up  to  $62.5  million  upon  achievement  of  specified  clinical  development  milestone  events  and  up  to  $12.0  million  upon 
achievement of specified regulatory milestone events in connection with specified regulatory filings and receipt of marketing 
approvals.

Notes to Consolidated Financial Statements — (Continued)

6.  Long-Term Debt, Net

Royalty-backed Loan

In January 2016, through our wholly-owned subsidiary Halozyme Royalty LLC (“Halozyme Royalty”), we received a $150 
million  loan  (the  “Royalty-backed  Loan”)  pursuant  to  a  credit  agreement  (the  “Credit Agreement”)  with  BioPharma  Credit 
Investments IV Sub, LP and Athyrium Opportunities II Acquisition LP (the “Royalty-backed Lenders”). Under the terms of the 
Credit Agreement, Halozyme Therapeutics, Inc. transferred to Halozyme Royalty the right to receive royalty payments from the 
commercial  sales  of  ENHANZE  products  owed  under  the  Roche  Collaboration  and  Baxalta  Collaboration  (“Collaboration 
Agreements”). The royalty payments from the Collaboration Agreements will be used to repay the principal and interest on the 
loan (the “Royalty Payments”).  The Royalty-backed loan bears interest at a per annum rate of 8.75% plus the three-month LIBOR
rate. The three-month LIBOR rate is subject to a floor of 0.7% and a cap of 1.5%. The interest rate as of December 31, 2016 was 
9.71%. 

The Credit Agreement provides that none of the Royalty Payments are required to be applied to the Royalty-backed Loan 
prior to January 1, 2017, 50% of the Royalty Payments are required to be applied to the Royalty-backed Loan between January 1, 
2017 and January 1, 2018 and thereafter all Royalty Payments must be applied to the Royalty-backed Loan. However, the amounts 
available to repay the Royalty-backed Loan are subject to caps of $13.75 million per quarter in 2017, $18.75 million per quarter 
in 2018, $21.25 million per quarter in 2019 and $22.5 million per quarter in 2020 and thereafter. Amounts available to repay the 
Royalty-backed Loan will be applied first, to pay interest and second, to repay principal on the Royalty-backed Loan. Any accrued 
interest that is not paid on any applicable quarterly payment date, as defined, will be capitalized and added to the principal balance 
of the Royalty-backed Loan on such date. Halozyme Royalty will be entitled to receive and distribute to Halozyme any Royalty 
Payments that are not required to be applied to the Royalty-backed Loan or which are in excess of the foregoing caps. 

Because the repayment of the term loan is contingent upon the level of Royalty Payments received, the repayment term may 
be shortened or extended depending on the actual level of Royalty Payments. The final maturity date of the Royalty-backed Loan 
will be the earlier of (i) the date when principal and interest is paid in full, (ii) the termination of Halozyme Royalty’s right to 
receive royalties under the Collaboration Agreements, and (iii) December 31, 2050. Currently, we estimate that the loan will be 
repaid in the first quarter of 2020. This estimate could be adversely affected and the repayment period could be extended if future 
royalty amounts are less than currently expected. Under the terms of the Credit Agreement, at any time after January 1, 2019, 
Halozyme Royalty may, subject to certain limitations, prepay the outstanding principal of the Royalty-backed Loan in whole or 
in part, at a price equal to 105% of the outstanding principal on the Royalty-backed Loan, plus accrued but unpaid interest. The 
Royalty-backed Loan constitutes an obligation of Halozyme Royalty, and is non-recourse to Halozyme. Halozyme Royalty retains 
its right to the Royalty Payments following repayment of the loan. 

As of December 31, 2016, we were in compliance with all material covenants under the Credit Agreement and there was no 

material adverse change in our business, operations or financial condition.

 During the year ended December 31, 2016, accrued interest in the amount of $13.2 million was capitalized and added to the 
principal balance of the Royalty-backed Loan. In addition, we recorded related accrued interest on the debt of $0.7 million as of 
December 31, 2016. 

 In connection with the Royalty-backed Loan, we paid the Royalty-backed Lenders a fee of $1.5 million and incurred additional 
debt issuance costs totaling $0.4 million, which includes expenses that we paid on behalf of the Royalty-backed Lenders and 
expenses incurred directly by us. Debt issuance costs and the lender fee have been netted against the debt as of December 31, 
2016,  and  are  being  amortized  over  the  estimated  term  of  the  debt  using  the  effective  interest  method.  For  the  year  ended 
December 31, 2016, the Company recognized interest expense, including amortization of the debt discount, related to the Royalty-
backed Loan of $14.5 million. The assumptions used in determining the expected repayment term of the debt and amortization 
period of the issuance costs requires that we make estimates that could impact the short- and long-term classification of these costs, 
as  well  as  the  period  over  which  these  costs  will  be  amortized.  The  outstanding  balance  of  the  Royalty-backed  Loan  as  of 
December 31, 2016 was $161.8 million, inclusive of payment-in-kind interest expense of $13.2 million and net of unamortized 
debt discount of $1.4 million.

Oxford and SVB Loan and Security Agreement

In December 2013, we entered into an Amended and Restated Loan and Security Agreement (the “Original Loan Agreement”) 
with Oxford Finance LLC (“Oxford”) and Silicon Valley Bank (“SVB”) (collectively, the “Lenders”), amending and restating in 
its entirety our previous loan agreement with the Lenders, dated December 2012. The Original Loan Agreement was scheduled to 
mature on January 1, 2018 and provided for an additional $20 million principal, bringing the total loan balance to $50 million. 
The proceeds were used for working capital and general business requirements.

Notes to Consolidated Financial Statements — (Continued)

In January 2015, we entered into a second amendment to the Original Loan Agreement with the Lenders, amending and 
restating the loan repayment schedules of the Original Loan Agreement. The amended and restated term loan repayment schedule 
provided for interest only payments through January 2016, followed by consecutive equal monthly payments of principal and 
interest in arrears starting in February 2016 and continuing through the previously established maturity date of January 2018. 
Consistent with our previous loan, the amended Original Loan Agreement provided for a 7.55% interest rate and a final interest 
payment equal to 8.5% of the original principal amount, or $4.25 million, which was due when the loan became due or upon the 
prepayment of the facility. 

In June 2016, we entered into a new Loan and Security Agreement (the “New Loan Agreement”) with the Lenders, providing 
a senior secured loan facility of up to an aggregate principal amount of $70.0 million, comprising a $55.0 million draw in June 
2016 and an additional $15.0 million tranche, which we have the option to draw during the second quarter of 2017. The initial 
proceeds carry an interest rate of 8.25% and were partially used to pay the outstanding principal and final payment owed on the 
amended Original Loan Agreement. The remaining proceeds, including any drawdown of the additional $15.0 million, are to be 
used for working capital and general business requirements. The remaining $15.0 million tranche is subject to an annual interest 
rate equal to the prime rate as reported in The Wall Street Journal on the draw-down date plus 4.75%. The repayment schedule 
provides for interest only payments for the first 18 months, followed by consecutive equal monthly payments of principal and 
interest in arrears through the maturity date of January 1, 2021. The New Loan Agreement provides for a final payment equal to 
5.5% of the initial $55.0 million principal amount and, if we exercise our option to draw an additional $15.0 million in 2017, 
7.25% of the principal amount of the second draw. The final payment is due when the New Loan Agreement becomes due or upon 
the prepayment of the facility. We have the option to prepay the outstanding balance of the New Loan Agreement in full, subject 
to a prepayment fee of 2% in the first year and 1% in the second year of the New Loan Agreement. 

In connection with the New Loan Agreement, the debt offering costs have been recorded as a debt discount in our condensed 
consolidated balance sheets which, together with the final payment and fixed interest rate payments, are being amortized and 
recorded as interest expense throughout the life of the loan using the effective interest rate method. 

The New Loan Agreement is secured by substantially all of the assets of the Company and our subsidiary, Halozyme, Inc., 
except that the collateral does not include any equity interests in Halozyme, Inc., any of our intellectual property (including all 
licensing, collaboration and similar agreements relating thereto), and certain other excluded assets. The New Loan Agreement 
contains customary representations, warranties and covenants by us, which covenants limit our ability to convey, sell, lease, transfer, 
assign or otherwise dispose of certain of our assets; engage in any business other than the businesses currently engaged in by us 
or reasonably related thereto; liquidate or dissolve; make certain management changes; undergo certain change of control events; 
create, incur, assume, or be liable with respect to certain indebtedness; grant certain liens; pay dividends and make certain other 
restricted payments; make certain investments; make payments on any subordinated debt; enter into transactions with any of our 
affiliates outside of the ordinary course of business or permit our subsidiaries to do the same; and make any voluntary prepayment 
of or modify certain terms of the Royalty-backed Loan. In addition, subject to certain exceptions, we are required to maintain with 
SVB our primary deposit accounts, securities accounts and commodities, and to do the same for our subsidiary, Halozyme, Inc.

The New Loan Agreement also contains customary indemnification obligations and customary events of default, including, 
among other things, our failure to fulfill certain of our obligations under the New Loan Agreement and the occurrence of a material 
adverse change which is defined as a material adverse change in our business, operations, or condition (financial or otherwise), a 
material impairment of the prospect of repayment of any portion of the loan, a material impairment in the perfection or priority 
of the Lender’s lien in the collateral or in the value of such collateral or the occurrence of an event of default under the Royalty-
backed Loan. In the event of default by us under the New Loan Agreement, the Lenders would be entitled to exercise their remedies 
thereunder, including the right to accelerate the debt, upon which we may be required to repay all amounts then outstanding under 
the New Loan Agreement, which could harm our financial condition.

 As of December 31, 2016, we were in compliance with all material covenants under the New Loan Agreement and there 

was no material adverse change in our business, operations or financial condition.

Stock Plan (“2011 Stock Plan”), which was approved by the stockholders on May 6, 2016 and provides for the grant of up to 44.2 
million shares of common stock to selected employees, consultants and non-employee members of our Board of Directors as stock 
options, stock appreciation rights, restricted stock awards, restricted stock unit awards and performance awards. The 2011 Stock 
Plan was approved by the stockholders. Awards are subject to terms and conditions established by the Compensation Committee 
of our Board of Directors. During the year ended December 31, 2016, we granted share-based awards under the 2011 Stock Plan. 
At December 31, 2016, 12,458,020 shares were subject to outstanding awards and 9,001,562 shares were available for future grants 
of share-based awards.

Cash flows resulting from tax deductions in excess of the cumulative compensation cost recognized for options exercised 
(excess tax benefits) are classified as cash inflows provided by financing activities and cash outflows used in operating activities. 
Due to our net loss position, no tax benefits have been recognized in the consolidated statements of cash flows.

Stock Options. Options granted under the Plans must have an exercise price equal to at least 100% of the fair market value 
of our common stock on the date of grant. The options generally have a maximum contractual term of ten years and vest at the 
rate of one-fourth of the shares on the first anniversary of the date of grant and 1/48 of the shares monthly thereafter. Certain option 
awards provide for accelerated vesting if there is a change in control (as defined in the Plans).

The weighted average grant date fair values of options granted during the years ended December 31, 2016, 2015 and 2014 
were $5.36 per share, $9.60 per share and $8.13 per share, respectively. The total intrinsic value of options exercised during the 
years ended December 31, 2016, 2015 and 2014 was approximately $1.4 million, $16.2 million and $8.1 million, respectively. 
Cash received from stock option exercises for the years ended December 31, 2016, 2015 and 2014 was approximately $2.8 million, 
$14.4 million and $7.8 million, respectively.

The fair value of each option award is estimated on the date of grant using the Black-Scholes-Merton option pricing model 
(“Black-Scholes model”) that uses the assumptions noted in the following table. Expected volatility is based on historical volatility 
of our common stock. The expected term of options granted is based on analyses of historical employee termination rates and 
option exercises. The risk-free interest rate is based on the U.S. Treasury yield for a period consistent with the expected term of 
the option in effect at the time of the grant. The dividend yield assumption is based on the expectation of no future dividend 
payments by us. Assumptions used in the Black-Scholes model were as follows:

Restricted Stock Awards. RSAs are grants that entitle the holder to acquire shares of our common stock at zero. The shares 
covered by a RSA cannot be sold, pledged, or otherwise disposed of until the award vests and any unvested shares may be reacquired 
by us for the original purchase price following the awardee’s termination of service. The RSAs will generally vest at the rate of 
one-fourth of the shares on each anniversary of the date of grant. Annual grants of RSAs to the Board of Directors typically vest 
in approximately one year.

Operating Leases

Our administrative offices and research facilities are located in San Diego, California. We lease an aggregate of approximately 
76,000 square feet of office and research space in four buildings. The leases commenced in June 2011 and November 2013 and 
continue through January 2018. The leases are subject to approximately 2.5% to 3.0% annual increases throughout the terms of 
the leases. We also pay a pro rata share of operating costs, insurance costs, utilities and real property taxes. We received incentives 
under the leases, including tenant improvement allowances and reduced or free rent, for which the unamortized deferred rent 
balances associated with these incentives was $0.4 million and $0.8 million as of December 31, 2016 and 2015, respectively.

In November 2015, we opened a satellite office in South San Francisco, California. We lease approximately 10,000 square 
feet  of  office  space.  The  lease  commenced  in  November  2015  and  continues  through  January  2021.  The  lease  is  subject  to 
approximately 3.0% annual increases throughout the term of the lease. We also pay a pro rata share of operating costs, insurance 
costs, utilities and real property taxes. We received incentives under the lease, including tenant improvement allowances and 
reduced or free rent, for which the unamortized deferred rent balances associated with these incentives was $0.4 million as of 
December 31, 2016 and 2015.

Additionally, we lease certain office equipment under operating leases. Total rent expense was approximately $2.2 million, 

$1.9 million and $1.9 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Other Commitments 

In  March  2010,  we  entered  into  a  second  Commercial  Supply Agreement  with Avid  (the  “Avid  Commercial  Supply 
Agreement”). Under the terms of the Avid Commercial Supply Agreement, we are committed to certain minimum annual purchases 
of bulk rHuPH20 equal to three quarters of forecasted supply. In addition, Avid has the right to manufacture and supply a certain 
percentage  of  bulk  rHuPH20  that  will  be  used  in  the  collaboration  products. At  December 31,  2016,  we  had  a  $13.0  million
minimum purchase obligation in connection with this agreement.

In June 2011, we entered into a services agreement with Patheon for the technology transfer and manufacture of Hylenex

recombinant. At December 31, 2016, we had a $0.7 million minimum purchase obligation in connection with this agreement.

In 2013 and 2014, we entered into service agreements with two third party manufacturers for the manufacturing of PEGPH20. 
At December 31, 2016, we had a $1.6 million and a $5.4 million minimum purchase obligation in connection with each of these 
agreements.

Contingencies

We have entered into an in-licensing agreement with a research organization, which is cancelable at our option with 90 days
written notice. Under the terms of this agreement, we have received license to know-how and technology claimed, in certain patents 
or patent applications. We are required to pay fees, milestones and/or royalties on future sales of products employing the technology 
or falling under claims of a patent, and some of the agreements require minimum royalty payments. We continually reassess the 
value of the license agreement. If the in-licensed and research candidate is successfully developed, we may be required to pay 
milestone payments of approximately $8.0 million over the life of this agreement in addition to royalties on sales of the affected 
products. Due to the uncertainties of the development process, the timing and probability of the remaining milestone and royalty 
payments cannot be accurately estimated.

From time to time, we may be involved in disputes, including litigation, relating to claims arising out of operations in the 
normal course of our business. Any of these claims could subject us to costly legal expenses and, while we generally believe that 
we have adequate insurance to cover many different types of liabilities, our insurance carriers may deny coverage or our policy 
limits may be inadequate to fully satisfy any damage awards or settlements. If this were to happen, the payment of any such awards 
could have a material adverse effect on our consolidated results of operations and financial position. Additionally, any such claims, 
whether or not successful, could damage our reputation and business. We currently are not a party to any legal proceedings, the 
adverse outcome of which, in management’s opinion, individually or in the aggregate, would have a material adverse effect on 
our consolidated results of operations or financial position.

 At December 31, 2016, our unrecognized tax benefit was $12.8 million. Of this amount, $0.2 million would affect the 
effective tax rate and $12.6 million would affect the effective tax rate in the event the valuation allowance was removed. Of the 
unrecognized tax benefits, we do not expect any significant changes to occur in the next 12 months. Interest and/or penalties related 
to uncertain income tax positions are recognized by us as a component of income tax expense. For the years ended December 31, 
2016, 2015 and 2014, we recognized no interest or penalties.

Notes to Consolidated Financial Statements — (Continued)

At December 31, 2016, we had federal and California research and development tax credit carryforwards of approximately 
$28.0 million and $16.1 million, respectively. The federal research and development tax credits will begin to expire in 2024 unless 
previously utilized. The California research and development tax credits will carryforward indefinitely until utilized. Additionally, 
we had Orphan Drug Credit carryforwards of $43.8 million which will begin to expire in 2035. 

Pursuant to Internal Revenue Code Section 382, the annual use of the net operating loss carryforwards and research and 
development tax credits could be limited by any greater than 50% ownership change during any three year testing period. As a 
result of any such ownership change, portions of our net operating loss carryforwards and research and development tax credits 
are subject to annual limitations. We completed an updated Section 382 analysis regarding the limitation of the net operating losses 
and research and development credits as of June 30, 2014. Based upon the analysis, we determined that ownership changes occurred 
in prior years. However, the annual limitations on net operating loss and research and development tax credit carryforwards will 
not have a material impact on the future utilization of such carryforwards.

We do not provide for U.S. income taxes on the undistributed earnings of our foreign subsidiaries as it is our intention to 
utilize those earnings in the foreign operations for an indefinite period of time. At December 31, 2016 and 2015, there were no
undistributed earnings in foreign subsidiaries.

We are subject to taxation in the U.S. and in various state and foreign jurisdictions. Our tax years for 1998 and forward are 
subject to examination by the U.S. and California tax authorities due to the carryforward of unutilized net operating losses and 
research and development credits.

11.  Employee Savings Plan

We have an employee savings plan pursuant to Section 401(k) of the Internal Revenue Code. All employees are eligible to 
participate, provided they meet the requirements of the plan. We are not required to make matching contributions under the plan. 
However, we voluntarily contributed to the plan approximately $1.0 million, $0.7 million and $0.7 million for the years ended 
December 31, 2016, 2015 and 2014, respectively.

12.  Restructuring Expense

In November 2014, we completed a corporate reorganization to focus our resources on advancing our PEGPH20 oncology 
proprietary program and ENHANZE collaborations. This reorganization resulted in a reduction in the workforce of approximately 
13%, primarily in research and development. 

We recorded approximately $1.2 million of severance pay and benefits expense in connection with the reorganization, of 
which $1.1 million and $0.1 million was included in research and development expense and selling, general and administrative 
expense, respectively, in the consolidated statement of operations for the year ended December 31, 2014. No other restructuring 
charges were incurred.

SAFE HARBOR STATEMENT

This Annual Report contains forward-looking statements regarding our products in development, 
anticipated clinical, regulatory and commercial milestones, business intentions, financial conditions 
and results of operations and prospects and other statements concerning future matters. Words 
such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” and similar 
expressions or variations of such words are intended to identify forward-looking statements, but 
are not the exclusive means of identifying forward-looking statements in the Annual Report. Actual 
results could differ materially from the expectations contained in forward-looking statements as a 
result of several factors, including unexpected expenditures and costs, unexpected results or delays 
in development and regulatory review, regulatory approval requirements, unexpected adverse 
events and competitive conditions. These and other factors that may result in differences are 
discussed in greater detail in the Company’s reports on Forms 10-K, 10-Q, and other filings with the 
Securities and Exchange Commission. 

Additional ENHANZE™ platform highlights in 

Overall, our ENHANZE platform continues to 

2016 included:

distinguish Halozyme and create great 

potential for future growth. 

Revenue for the year was $147 million, an 

8.6 percent increase over 2015, and we exited 

the year well-financed with $205 million  

in cash.   

  Throughout the year, we created 

long-term value for our shareholders as we 

advanced toward our goal to become a 

leading global oncology biotechnology 

company. Each day we make progress toward 

our goal, we strengthen a commitment to the 

patients we serve and those we may serve in 

the future. They remain the focus of all that 

we do.

Thank you for your continued support.

•  Royalty revenue growing 65 percent as three  

  partnered products from Shire and Roche  

  continue to increase use around the globe by  

  patients and health care practitioners.   

•  Acceptance by the FDA of Genentech’s  

  biologic license application for subcutaneous  

rituximab in non-Hodgkin’s lymphoma and  

  chronic lymphocytic leukemia. This co- 

formulation with our ENHANZE technology is  

  already approved and marketed under the  

  MabThera® SC brand in countries outside the  

  U.S. Including all approved indications, Roche  

reported total 2015 sales of rituximab in the  

  U.S. of approximately $3.5 billion and analysts  

  estimate the majority of these sales are blood  

  cancer related, making this one of the biggest  

  potential opportunities in ENHANZE franchise  

  history. Upon regulatory approvals, our royalty  

revenues will depend on the degree of market  

  penetration and indications, with the potential  

to create another significant inflection in  

  Halozyme royalty revenue.

•  Janssen presented compelling data from a  

  phase 1 trial of oncology drug daratumumab  

  with the ENHANZE platform indicating that,  

instead of a multi-hour intravenous infusion,  

  daratumumab may be delivered in  

  30 minutes with similar efficacy as a  

  subcutaneous administration. Analysts  

  estimate that sales of daratumumab may top  

  $7 billion by 2025. A phase 3 study is being  

  planned and Janssen recently took steps to  

  file for patent protection for the co-formulation.

•  During the year, Pfizer and AbbVie  

  discontinued three development projects  

  with the ENHANZE platform which, while  

  disappointing, can be expected in early stage  

  programs. We have very strong ongoing  

relationships with both companies. Pfizer  

  continues in development with one of their  

two remaining targets and AbbVie has nine  

targets under the agreement we formed  

in 2015.
