CONCLUSION

We recently hosted Halozyme for investor meetings and came away with enhanced

conviction in the company's long-term ENHANZE strategy, as well as the potential of

PEGPH20 inclusive of but even beyond pancreatic cancer. We are raising our PT from

$26 to $29 in anticipation of value creation from ENHANZE progress (within current

collaborations and potentially from 1-2 new ones), plus several Phase I/II PEGPH20 combo

studies in the next 12-18 months. We continue to believe investors are overlooking the

risk-reduced growth prospects in each two pillars of the business, as well as the synergies

between them, with more details on our outlook below. In advance of increasingly visible

clinical and commercial progress for Halozyme, we reiterate OW.

• ENHANZE Momentum Building. We believe investors may be underestimating the

long-term value from ENHANZE. Specifically, we see three factors as driving this value.

First, the Rituxan Hycela Ad Comm earlier this year clarified the regulatory path in

the eyes of current or potential ENHANZE partners. Second, we perceive growing

appreciation for ENHANZE products as not just supporting life cycle management, but

as driving true innovation in the form of meaningful patient/provider preferences and

potentially improved clinical outcomes. For example, the Phase I Darzalex SC study

demonstrated a significant improvement in administration times (multiple hour infusion

to minutes long injection) and a decrease in infusion reaction rates, all of which should

support compliance and outcomes, over time. Third, we believe the commercial value

proposition of an SC product is well suited for the EU, and more recently the US market,

in terms of cost savings for the increasingly cost-constrained system and, for individual

prescribers, a decreasing profit differential between IV and SC drugs in oncology. Please

see Exhibit 1 for a summary of ENHANZE products and progress we'll be tracking in

the next twelve months. Overall, we believe the above factors will lead to accelerated

progress within Halozyme's seven existing collaborations (Exhibit 2) and at least one

new high value collaboration in the next ~12-18 months.

• PEGPH20 - More than just PC. Following these recent meetings, we continue to believe

investors may be overlooking value creation from PEGPH20 in multiple solid tumor types.

On pancreatic cancer and relative to other recent attempts by other sponsors, we believe

this program is significantly risk reduced by the prospective, placebo controlled Phase II

dataset, mechanism which enhances SOC, and rationally selected patient group. Each of

these factors differentiates the PEGPH20 program from recent failures to translate Phase

II activity to positive Phase III results, in our view. We expect enrollment to complete in

1H18 to support a PFS interim in (if we had to hazard a timeline) 2019.


Beyond PC, also gleaned from the roadshow, we have a refreshed perspective on the potential

of PEGPH20 to enhance response rates to IO agents. Specifically, in animal models PEGPH20

increases the concentration of these drugs in the tumor by 40-80%, as well as increasing immune

cell infiltration of the tumor micro environment (TME). We also anticipate several updates from

one of the multiple combo trials (ongoing or about to start) approximately every six months for

the next two years - Exhibit 3. If demonstrated data is promising, these could support signing

further partnerships for capital efficient late-stage clinical development.

Model updates: Price Target to $29. Based on the above updates, today we are incrementally

reducing our discount rate on future ENHANZE royalty revenue streams from 12% to 10%.

In addition, we are adding in a $250M pipeline placeholder value for the IO combination

opportunities with PEGPH20. Finally, we are pushing first sales of PEGPH20 back to 2020 from

2019 to align with timelines for that study; enrollment is progressing as expected and our model

projection was likely somewhat aggressive on investigative site initiation timelines. Finally, we

believe the BMS up-front will hit the P+L during 4Q17 versus 3Q17, and are updating our model

accordingly. Overall, these changes result in a price target of $29 up from $26 - Exhibit 4.
