FOR THE THREE MONTHS ENDED DECEMBER 31, 2017 and 2016

ESSA Pharma Inc. (the “Company”) was incorporated under the laws of the Province of British Columbia on January 6, 2009. The Company’s head office address is Suite 720 - 999 West Broadway, Vancouver, BC, V5Z 1K5. The registered and records office address is the 26^th Floor at 595 Burrard Street, Three Bentall Centre, Vancouver, BC, V7X 1L3. The Company is listed on the NASDAQ Capital Market (“NASDAQ”) under the symbol “EPIX”, and on the Toronto Venture Exchange (“TSX-V”) under the symbol “EPI”.

The Company is focused on the development of small molecule drugs for the treatment of prostate cancer. The Company has acquired a license to certain patents (the “NTD Technology”) which were the joint property of the British Columbia Cancer Agency and the University of British Columbia. As at December 31, 2017, no products are in commercial production or use. From November 2015 until September 2017, the Company’s primary activity was the Phase I clinical development of clinical candidate EPI-506. On September 11, 2017, the Company announced its decision to discontinue further clinical development of EPI-506 and to implement a corporate restructuring plan to focus research and development resources on its next-generation compounds. The restructuring included a decrease in headcount and reduction of operational expenditures related to the clinical program.

These financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) assuming the Company will continue on a going-concern basis. The Company has incurred losses and negative operating cash flows since inception. The Company incurred a net loss of $2,131,768 during the three months ended December 31, 2017 and has an accumulated deficit of $34,871,414. The ability of the Company to continue as a going concern in the long-term depends upon its ability to develop profitable operations and to continue to raise adequate financing. As at December 31, 2017, the Company has not advanced its research into a commercially viable product. The Company’s continuation as a going concern is dependent upon the successful development of its NTD Technology to a commercial standard.

Subsequent to December 31, 2017, the Company completed a financing of $26,000,000 in gross proceeds (Note 19). Management continues to seek sources of additional financing which would assure continuation of the Company’s operations and research programs. However, there is no certainty that such financing will be provided or provided on favorable terms. Management believes that it will complete a financing in sufficient time to continue to execute its planned expenditures without interruption.

These condensed consolidated interim financial statements, including comparatives, have been prepared in accordance with International Accounting Standards (“IAS”) 34 ‘Interim Financial Reporting’ (“IAS 34”) using accounting policies consistent with International Financial Reporting Standards (“IFRS”) issued by the International Accounting Standards Board (“IASB”) and Interpretations of the International Financial Reporting Interpretations Committee (“IFRIC”).

The condensed consolidated interim financial statements do not include all the information and disclosures required in the annual consolidated financial statements and should be read in conjunction with the Company’s annual consolidated financial statements for the year ended September 30, 2017.

The condensed consolidated interim financial statements have been prepared on a historical cost basis except for certain financial assets measured at fair value. In addition, these condensed consolidated interim financial statements have been prepared using the accrual basis of accounting, except for cash flow information.

All amounts expressed in these condensed consolidated interim financial statements and the accompanying notes are expressed in United States dollars, except per share data and where otherwise indicated. References to “$” are to United States dollars and references to “C$” are to Canadian dollars.

The condensed consolidated interim financial statements comprise the accounts of ESSA Pharma Inc., the parent company, and its wholly-owned subsidiary, ESSA Pharmaceuticals Corp., after the elimination of all material intercompany balances and transactions.

Subsidiaries are all entities over which the Company has exposure to variable returns from its involvement and has the ability to use power over the investee to affect its returns. The existence and effect of potential voting rights that are currently exercisable or convertible are considered when assessing whether the Company controls another entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Company until the date on which control ceases.

The accounts of subsidiaries are prepared for the same reporting period as the parent company, using consistent accounting policies. Inter-company transactions, balances and unrealized gains or losses on transactions are eliminated upon consolidation.

The functional currency of an entity is the currency of the primary economic environment in which the entity operates. From inception to January 1, 2016, the functional currency of the Company has been the Canadian dollar and its subsidiary’s the United States dollar. The functional currency determinations were conducted through an analysis of the consideration factors identified in IAS 21, The Effects of Changes in Foreign Exchange Rates. The financing completed in January 2016 and changes to the Company’s operations have resulted in a change to the currency in which the Company’s management conducts its operating, capital and financing decisions. Consequently, the functional currency of the Company became the US$ effective January 1, 2016.

These financial statements are presented in United States dollars. All financial information is expressed in United States dollars unless otherwise stated.

The Company makes estimates and assumptions about the future that affect the reported amounts of assets and liabilities. Estimates and judgments are continually evaluated based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. In the future, actual results may differ from these estimates and assumptions.

The effect of a change in an accounting estimate is recognized prospectively by including it in comprehensive income in the period of the change, if the change affects that period only, or in the period of the change and future periods, if the change affects both. Significant assumptions about the future and other sources of estimation uncertainty that management has made at the statement of financial position date, that could result in a material adjustment to the carrying amounts of assets and liabilities, in the event that actual results differ from assumptions that have been made, relate to the following key estimates:

The application of the Company’s accounting policy for intangible assets expenditures requires judgment in determining whether it is likely that future economic benefits will flow to the Company, which may be based on assumptions about future events or circumstances. Estimates and assumptions may change if new information becomes available. If, after expenditures are capitalized, information becomes available suggesting that the recovery of expenditures is unlikely, the amount capitalized is written off in profit or loss in the period the new information becomes available.

Following initial recognition, the Company carries the value of intangible assets at cost less accumulated amortization and any accumulated impairment losses. Amortization is recorded on a straight-line basis based upon management’s estimate of the useful life and residual value. The estimates are reviewed at least annually and are updated if expectations change as a result of technical obsolescence or legal and other limits to use. A change in the useful life or residual value will impact the reported carrying value of the intangible assets resulting in a change in related amortization expense.

Pursuant to the terms of the Company’s grant from the Cancer Prevention Research Institute of Texas (“CPRIT”), the Company must meet certain terms and conditions to qualify for the grant funding. The Company has assessed its performance relative to these terms as detailed in Note 17 and has judged that there is reasonable assurance the Company will meet the terms of the grant and qualify for the funding. The Company has therefore recognized in profit or loss, as recoveries of research and development expenditures, a portion of the grant that represents expenses the Company has incurred to date under the grant parameters. The expenses are subject to assessment by CPRIT for compliance with the grant regulations which may result in certain expenses being denied and incurred in a future period.

The Company has made certain estimates regarding the expected timing of and value of cash flows with respect to long-term debt. The estimates will fluctuate in accordance with changes in interest rates and any prepayments made, should the Company elect to do so (Note 7).

Certain warrants are treated as derivative financial liabilities. The estimated fair value, based on the Black-Scholes model, is adjusted on a quarterly basis with gains or losses recognized in the statement of loss and comprehensive loss. The Black-Scholes model is based on significant assumptions such as volatility, dividend yield, expected term and liquidity discounts (Note 8).

The Company has applied estimates with respect to the valuation of shares issued for non-cash consideration. Shares are valued at the fair value of the equity instruments granted at the date the Company receives the goods or services.

The Company measures the cost of equity-settled transactions with employees by reference to the fair value of the equity instruments at the date at which they are granted. Estimating fair value for share-based payment transactions requires determining the most appropriate valuation model, which is dependent on the terms and conditions of the grant. This estimate also requires determining the most appropriate inputs to the valuation model including the fair value of the underlying common shares, the expected life of the share option, volatility and dividend yield and making assumptions about them. The Company makes reference to prices quoted on the TSX and NASDAQ. The assumptions and models used for estimating fair value for share-based payment transactions are discussed in Note 10.

IFRS 9 was issued by the IASB in October 2010. It incorporates revised requirements for the classification and measurement of financial liabilities and carrying over the existing derecognition requirements from IAS 39 Financial Instruments: recognition and measurement. The revised financial liability provisions maintain the existing amortized cost measurement basis for most liabilities. New requirements apply where an entity chooses to measure a liability at fair value through profit or loss - in these cases, the portion of the change in fair value related to changes in the entity's own credit risk is presented in other comprehensive income rather than within profit or loss. IFRS 9 is effective for annual periods beginning on or after January 1, 2018. IFRS 9 is not expected to have a significant impact on the Company’s condensed consolidated interim financial statements.

IFRS 15 is a new standard to establish principles for reporting the nature, amount, timing, and uncertainty of revenue and cash flows arising from an entity’s contracts with customers. It provides a single model in order to depict the transfer of promised goods or services to customers. IFRS 15 supersedes IAS 11, Construction Contracts, IAS 18, Revenue, IFRIC 13, Customer Loyalty Programs, IFRIC 15, Agreements for the Construction of Real Estate, IFRIC 18, Transfers of Assets from Customers, and SIC-31, Revenue - Barter Transactions involving Advertising Service. IFRS 15 is effective for annual periods beginning on or after January 1, 2018. IFRS 15 is not expected to have a significant impact on the Company’s financial statements.

IFRS 16 is a new standard that sets out the principles for recognition, measurement, presentation, and disclosure of leases including guidance for both parties to a contract, the lessee and the lessor. The new standard eliminates the classification of leases as either operating or finance leases as is required by IAS 17 and instead introduces a single lessee accounting model. IFRS 16 is effective for annual periods beginning on or after January 1, 2019. The impact of IFRS 16 on the Company’s leases has not yet been determined.

Amortization expense has been recorded in “general and administrative expenses” in the statement of loss and comprehensive loss (Note 18).

The NTD Technology is held under a License Agreement signed in fiscal 2010. As consideration for the License Agreement, the Company issued common shares of the Company. The License Agreement contains an annual royalty as a percentage of annual net revenue and a percentage of any annual sublicensing revenue earned with respect to the NTD Technology. The License Agreement stipulates certain minimum advance royalty payments of C$85,000. In addition, there are certain milestone payments for the first compound, to be paid in stages as to C$50,000 at the start of a Phase II clinical trial, C$900,000 at the start of a Phase III clinical trial, C$1,450,000 at application for marketing approval, and with further milestone payments on the second and additional compounds.

On November 18, 2016, Silicon Valley Bank (“SVB”) entered into a $10,000,000 capital term loan facility agreement (“SVB Term Loan”) with the Company. The Company has drawn down $8,000,000 from the SVB Term Loan. There was a conditional option to receive an additional $2,000,000 upon positive data for the Company’s Phase 1 clinical trial of EPI-506 and receipt of the third and final tranche of the CPRIT grant.

The SVB Term Loan bears an interest rate of the Wall Street Journal Prime Rate (“WSJ Prime Rate”) plus 3% per annum and will mature on September 1, 2020. The SVB Term Loan requires a final payment of 8.6% of the amount advanced (“Final Payment”), due upon the earlier of the maturity or termination of the SVB Term Loan. The Company is required to make interest only payments until December 31, 2017. The SVB Term Loan contains a voluntary prepayment option whereby the principal amount can be prepaid in whole, or in part, for a fixed fee if a prepayment is made on or before the second anniversary of the SVB Term Loan.

The SVB Term Loan is secured by a perfected first priority lien on all of the Company’s assets, with a negative pledge on the Company’s intellectual property. The SVB Term Loan is subject to standard events of default, including default in the event of a material adverse change. SVB may declare the Company to be in breach of the agreement in the event of a material adverse change, which has been defined to include a material impairment in the Company’s assets acting as collateral under the SVB Term Loan, a material adverse change in the business, operations, or condition (financial or otherwise) of the Company, or a material impairment of the prospect of repayment of any portion of its debt obligations. There are no financial covenants under the SVB Term Loan.

In connection with the $8,000,000 draw, the Company granted an aggregate of 149,532 warrants to SVB (the “SVB Warrants”), exercisable at a price of $2.14 per share for a period of seven years until November 18, 2023, with an initial fair value of $167,022, which has been recognized as a derivative liability (Note 8). The Company incurred total additional transaction costs of $220,898 related to the SVB Term Loan and First Amendment. The transaction costs and Final Payment are being amortized into profit and loss over the estimated term of the facility, being the legal term, at an effective interest rate of 11.87%.

In accordance with IFRS, an obligation to issue shares for a price that is not fixed in the Company’s functional currency, and that does not qualify as a rights offering, must be classified as a derivative liability and measured at fair value with changes recognized in the statement of loss and comprehensive loss as they arise. The derivative liability was designated as a financial liability carried at fair value through profit and loss.

Warrants exercisable in US dollars prior to January 1, 2016 and warrants exercisable in Canadian dollars after January 1, 2016, the date marking the Company’s change in functional currency, are therefore classified as derivative liabilities.

In 2015, the Company issued 257,018 broker warrants. Each broker warrant was exercisable to purchase one common share until January 16, 2017 at a price of US$2.75 per broker warrant (Note 10). On issuance of the broker warrants, the Company recorded a derivative liability of $282,287 using the Black-Scholes model. As at December 31, 2015, the derivative liability had a fair value of $588,407, using the Black-Scholes model with a risk-free interest rate of 0.52%, term of 1.04 years, volatility of 80.0%, and dividend rate of 0%. On January 1, 2016, the Company de-recognized the derivative liability of $588,407. On January 16, 2017, the remaining 256,363 outstanding warrants expired unexercised.

In April 2014, in connection with the issuance of a convertible debenture for $1,000,000, the Company issued 25,000 broker warrants valued at $14,935 (C$16,394), each exercisable into one common share at a price of C$2.00 for a period of five years (Note 10). The warrants were valued using the Black-Scholes model with a risk-free interest rate of 1.63%, term of 5 years, volatility of 80% and dividend rate of 0%.

On January 1, 2016, the Company recorded a derivative liability of $82,743 using the Black-Scholes model. As at December 31, 2017, the derivative liability had a fair value of $55 (September 30, 2017 - $206). The Company has recorded the resulting change in fair value of $151 (2016 - $14,130) in the statement of loss and comprehensive loss.

In January 2016, the Company completed a private placement of 4,545,452 units of the Company at $3.30 per unit (“Unit”) for gross proceeds of $14,999,992. Each Unit consisted of one common share of the Company, one 7-year cash and cashless exercise warrant (the “7-Year Warrants”), and one half of one 2-year cash exercise warrant (the “2-Year Warrants”). The 7-Year Warrants and 2-Year Warrants have an exercise price of $3.30 per common share (collectively, the “2016 Warrants”). The holders of the 7-Year Warrants may elect, in lieu of exercising the 7-Year Warrants for cash, a cashless exercise option, in whole or in part, to receive common shares equal to the fair value of the 7-Year Warrants based on the number of 7-Year Warrants to be exercised multiplied by a ten-day weighted average market price less the exercise price with the difference divided by the weighted average market price. If a warrant holder exercises this option, there will be variability in the number of shares issued per 7-Year Warrant.

Additionally, the 2016 Warrants contain provisions which may require the Company to redeem the 2016 Warrants, at the option of the holder, in the event of a major transaction, such as a change of control or sale of the Company’s assets (“Major Transaction”). The redemption value would be subject to a Black-Scholes valuation at the time of exercise. In the event the consideration for a Major Transaction payable to the common shareholders is in cash, in whole or in part, the redemption of the 2016 Warrants would be made in cash pro-rata to the composition of the consideration. The potential for a cash settlement for the 2016 Warrants, in accordance with IFRS, requires the 2016 Warrants to be treated as financial liabilities measured at fair value through profit or loss.

On issuance of the 7-Year and 2-Year Warrants in January 2016, the Company recorded derivative liabilities of $10,181,817 and $3,236,363, respectively using the Black-Scholes model. The 2016 Warrants are not traded in an active market. A liquidity discount of 20% has been applied to the per warrant fair value to account for the lack of marketability of the instruments. As at December 31, 2017, the 7-Year Warrants derivative liability had a fair value of $74,212 (September 30, 2017 - $160,262). As at December 31, 2017, the 2-Year Warrants derivative liability had a fair value of $Nil (September 30, 2017 - $Nil). The Company has recorded the resulting change in fair value of $86,050 (2016 - $1,980,245) in the statement of loss and comprehensive loss.

In connection with the $8,000,000 draw on the SVB Term Loan (Note 7), the Company granted an aggregate of 149,532 warrants to SVB (the “SVB Warrants”), exercisable at a price of $2.14 per share for a period of seven years until November 18, 2023. The holders of the SVB Warrants may elect, in lieu of exercising the SVB Warrants for cash, a cashless exercise option, in whole or in part, to receive common shares equal to the fair value of the SVB Warrants based on the number of SVB Warrants to be exercised multiplied by a five-day weighted average market price less the exercise price with the difference divided by the weighted average market price. If a warrant holder exercises this option, there will be variability in the number of shares issued per SVB Warrant.

Additionally, the SVB Warrants contain provisions which require the Company to redeem the SVB Warrants, on a cashless basis, at the option of the holder, in the event of a major transaction, such as a change of control or sale of the Company’s assets (“Acquisition”) where the Company’s shareholders receive cash or shares or a combination thereof, and the five-day weighted average market price is greater than the exercise price.

On issuance of the SVB Warrants, the Company recorded a derivative liability of $167,022 using the Black-Scholes model. The SVB Warrants are not traded in an active market. A liquidity discount of 20% has been applied to the per warrant fair value to account for the lack of marketability of the instruments. As at December 31, 2017, the SVB Warrants derivative liability had a fair value of $7,913 (September 30, 2017 - $10,275). The Company has recorded the resulting change in fair value of $2,362 (2016 - $Nil) in the statement of loss and comprehensive loss.

The Company uses the Black-Scholes option pricing model to estimate value. The following weighted average assumptions were used to estimate the fair value of the derivative warrant liabilities on initial recognition (January 1, 2016 with respect to the broker warrants, January 14, 2016 with respect to the 2016 Warrants, November 18, 2016 with respect to the SVB Warrants), September 30, 2016, and December 31, 2017:

The derivative warrants are a recurring Level 3 fair value measurement. The key level 3 inputs used by management to determine the fair value are the market price and expected volatility. If the market price were to increase by a factor of 10% this would increase the obligation by approximately $19,457 as at December 31, 2017. If the market price were to decrease by a factor of 10% this would decrease the obligation by approximately $14,141 as at December 31, 2017. If the volatility were to increase by 10%, this would increase the obligation by approximately $42,053 as at December 31, 2017. If the volatility were to decrease by 10%, this would decrease the obligation by approximately $30,901 as at December 31, 2017.

There were no changes to the Company’s approach to capital management during the three months ended December 31, 2017. As at December 31, 2017, the Company is not subject to externally imposed capital requirements.

The Company’s financial instruments consist of cash, receivables, accounts payable and accrued liabilities, long-term debt and derivative liabilities. Cash is measured based on level 1 inputs of the fair value hierarchy. The fair value of receivables and accounts payable and accrued liabilities approximates their carrying values due to their short term to maturity. The fair value of the SVB Term Loan is approximately $8,739,000 which includes the principal and financing costs assessed on settlement as at December 31, 2017. The derivative liabilities are measured using level 3 inputs (Note 8).

Fair value estimates of financial instruments are made at a specific point in time, based on relevant information about financial markets and specific financial instruments. As these estimates are subjective in nature, involving uncertainties and matters of judgement, they cannot be determined with precision. Changes in assumptions can significantly affect estimated fair values.

The Company’s risk exposures and the impact on the Company’s financial instruments are summarized below:

Financial instruments that potentially subject the Company to a significant concentration of credit risk consist primarily of cash and receivables. The Company’s receivables are primarily due to refundable GST and investment tax credits. The Company limits its exposure to credit loss by placing its cash with major financial institutions. Credit risk with respect to investment tax credits and GST is minimal as the amounts are due from government agencies.

The Company’s approach to managing liquidity risk is to ensure that it will have sufficient liquidity to meet liabilities when due. As at December 31, 2017, the Company had a working capital deficiency of $1,643,594. The SVB Term Loan is repayable over 33 months following an interest-only period ending December 31, 2017. The Company does not generate revenue and will be reliant on external financing to fund operations and repay the SVB Term Loan. Debt and equity financing is dependent on market conditions and may not be available on favorable terms. The CPRIT grant is dependent on the Company completing all the milestones (Note 17). Subsequent to December 31, 2017, the Company completed a financing for total gross proceeds of $26,000,000 (Note 19).

Market risk is the risk of loss that may arise from changes in market factors such as interest rates, and foreign exchange rates.

FOR THE THREE MONTHS ENDED DECEMBER 31, 2017 and 2016

As at December 31, 2017, the Company has cash balances which are interest bearing. Interest income is not significant to the Company’s projected operational budget and related interest rate fluctuations are not significant to the Company’s risk assessment.

The Company’s SVB Term Loan is interest-bearing debt at a variable rate. A 10% change in the WSJ Prime Rate would result in an increase of $12,389 or decrease of $5,611 in the net loss realized for the period.

Historically, the Company has been exposed to foreign currency risk on fluctuations related to accounts payable and accrued liabilities that are denominated in US dollars as the Company was financed and functioning in Canadian dollars. Over time, the Company has become increasingly exposed to the US dollar due to the financings completed in US dollars, the US dollar-denominated CPRIT Grant (Note 17) and movement of operations to the State of Texas pursuant to the terms of the CPRIT Grant; accordingly, the Company adopted the US dollar as its functional currency from the Canadian dollar as of January 1, 2016, so that the Company’s foreign currency risk exposure now relates to net monetary assets denominated in Canadian dollars. A 10% change in the foreign exchange rate between the Canadian and U.S. dollar would result in a fluctuation of $44,024 in the net loss realized for the period. The Company does not currently engage in hedging activities.

The Company is exposed to price risk with respect to equity prices. The Company closely monitors individual equity movements, and the stock market to determine the appropriate course of action to be taken by the Company.

In February 2014 the Company received notice that it had been awarded a product development and relocation grant by the CPRIT whereby the Company is eligible to receive up to $12,000,000 on eligible expenditures over a three year period related to the development of the Company’s androgen receptor n-terminus blocker program for prostate cancer. The funding under CPRIT is subject to a number of conditions including negotiation and execution of an award contract which details the milestones that must be met to release the tranched CPRIT funding, proof the Company has raised the 50% matching funds to release CPRIT monies, and relocation of the project to the State of Texas such that the substantial functions of the Company related to the project grant are in Texas and the Company uses Texas-based subcontractor and collaborators wherever possible.

As at September 30, 2016, the Company had received the first two tranches of the CPRIT Grant, totalling $6,578,000, which have been recognized as research and development recoveries in the statements of loss and comprehensive loss over fiscal years 2014, 2015, and 2016. During the year ended September 30, 2017, the Company received $5,192,799, representing a partial payment of the third and final tranche of the grant of $5,422,000; the remaining balance of $229,201 is expected to be received after the completion of the grant term of December 31, 2017 and on approval of subsequent final compliance reporting.

If the Company is found to have used any grant proceeds for purposes other than intended, is in violation of the terms of the grant, or relocates its operations outside of the State of Texas, then the Company is required to repay any grant proceeds received.

Under the terms of the grant, the Company is also required to pay a royalty to CPRIT, comprised of 4% of revenues until aggregate royalty payments equal $24,000,000, and 2% of revenues thereafter. The Company has the option to terminate the grant agreement by paying a one-time, non-refundable buyout fee, based on certain factors including the grant proceeds, and the number of months between the termination date and the buyout fee payment date.

In the year ended September 30, 2017, the Company executed Engagement Letters with Bloom Burton & Co. (“Bloom Burton”) and H.C. Wainwright & Co. (“HCW”), investment banks, to retain their services to act as its exclusive agents in Canada and the United States, respectively, in connection with a proposed financing in July 2017. In exchange for their services, on successful completion of the financing, Bloom Burton and HCW would receive a cash fee based on a percentage of any funds raised and warrants based on a percentage of the aggregate number of common shares placed in the financing. The Company will pay all legal and other expenses incurred by Bloom Burton and HCW. In addition, for a period of 12 months, HCW will have a right of participation to act as a placement agent or underwriter on any equity financings for the Company, for which HCW shall receive a fee of no less than 25% of the fee on such financings.
