Summary Financial Results

• Net Income (Loss). ESSA recorded a net loss of $4.5 million ($0.15 loss per common share) for the year ended September 30, 2017, compared to a net loss of $13.1 million ($0.49 loss per common share) for the year ended September 30, 2016. The net loss for the fourth quarter of 2017 was $1.9 million compared to a net loss of $4.2 million for the fourth quarter of 2016.
  
  
• Research and Development ("R&D") expenditures. R&D expenditures for the year ended September 30, 2017 were $5.73 million net of grants ($10.92 million gross) compared to $13.6 million (net and gross), for the year ended September 30, 2016. For the fourth quarter ended September 30, 2017, R&D expenditures were $1.2 million compared to $3.9 million for the fourth quarter ended September 30, 2016. Decreases in R&D expenditures for the full year and fourth quarter were primarily related to decreases in manufacturing and clinical trial costs as the Company approached the completion of the Phase I clinical study of EPI-506, compared to the full year and fourth quarter ended September 30, 2016, as the Company ramped up its clinical development of EPI-506, which commenced in November 2015.
  
  
• General and administration ("G&A") expenditures. G&A expenditures for the year ended September 30, 2017 were $5.1 million compared to $5.6 million for the year ended September 30, 2016. For the fourth quarter ended September 30, 2017, G&A expenditures were $1.1 million compared to $1.2 million for the fourth quarter ended September 30, 2016. The decreases in the full year and fourth quarter primarily reflects the reduction in administrative costs, as well as reduced share-based payments reflecting vesting of stock options granted in previous years.

Liquidity and Outstanding Share Capital

Cash on hand as at September 30, 2017 was $3.98 million, with working capital of $1.28 million, reflecting the $2.0 current portion of the SVB Term Loan, for which repayment obligations commence in January 2018.

About ESSA Pharma Inc.

ESSA is a pharmaceutical company focused on developing novel and proprietary therapies for the treatment of castration-resistant prostate cancer ("CRPC") in patients whose disease is progressing despite treatment with current therapies. ESSA believes that its proprietary compounds can significantly expand the interval of time in which patients suffering from CRPC can benefit from hormone-based therapies, by disrupting the androgen receptor ("AR") signaling pathway that drives prostate cancer growth and by preventing AR transcriptional activity by binding selectively to the N-terminal domain ("NTD") of the AR. A functional NTD is essential for transactivation of the AR. In preclinical studies, blocking the NTD has demonstrated the capability to overcome the known AR-dependent mechanisms of CRPC. ESSA was founded in 2009.

About Prostate Cancer

Prostate cancer is the second-most commonly diagnosed cancer among men and the fifth most common cause of male cancer death worldwide (Globocan, 2012). Adenocarcinoma of the prostate is dependent on androgen for tumor progression and depleting or blocking androgen action has been a mainstay of hormonal treatment for over six decades. Although tumors are often initially sensitive to medical or surgical therapies that decrease levels of testosterone, disease progression despite castrate levels of testosterone generally represents a transition to the lethal variant of the disease, metastatic CPRC ("mCRPC"), and most patients ultimately succumb to the illness. The treatment of mCRPC patients has evolved rapidly over the past five years. Despite these advances, additional treatment options are needed to improve clinical outcomes in patients, particularly those who fail existing treatments including abiraterone or enzalutamide, or those who have contraindications to receive those drugs. Over time, patients with mCRPC generally experience continued disease progression, worsening pain, leading to substantial morbidity and limited survival rates. In both in vitro and in vivo animal studies, ESSA's novel approach to blocking the androgen pathway has been shown to be effective in blocking tumor growth when current therapies are no longer effective.
