Nature of Operations [Abstract]

Nature of Operations [Text Block]

1.	Nature of Operations

Stellar Biotechnologies, Inc. (the Company) is organized under the laws of British Columbia, Canada. The Company’s business is the aquaculture, research and development, manufacture and commercialization of Keyhole Limpet Hemocyanin (KLH). The Company markets and distributes its KLH products to biotechnology and pharmaceutical companies, academic institutions, and clinical research organizations primarily in Europe, Asia, and the United States. The Company’s common shares have been listed for trading on The Nasdaq Capital Market in the United States under the symbol “SBOT” since November 5, 2015.

In April 2010, the Company changed its name from CAG Capital, Inc. to Stellar Biotechnologies, Inc. and completed a reverse merger transaction with Stellar Biotechnologies, Inc., a California corporation, which was founded in September 1999, and remains the Company’s wholly-owned subsidiary and principal operating entity. In January 2017, the California subsidiary and the Company established a wholly-owned Mexican subsidiary under the name BioEstelar, S.A. de C.V. in Ensenada, Baja California to perform aquaculture research and development activities in Mexico. On March 29, 2019, the Company entered into an agreement to sell BioEstelar rather than pursue a more costly wind-down of the subsidiary. The Company’s executive offices are located at 332 E. Scott Street, Port Hueneme, California, 93041, USA, and its registered and records office is 1500 Royal Centre, 1055 West Georgia Street, Vancouver, BC, V6E 4N7, Canada.

On March 7, 2019, the Company entered into a Share

Exchange Agreement (the Exchange Agreement) with Edesa Biotech Inc., a privately-held Canadian company focused on the development of innovative therapeutics for dermatological and gastrointestinal indications (Edesa), and its shareholders. Upon the terms and subject to the satisfaction of the conditions described in the Exchange Agreement, including approval of the transaction by Stellar’s shareholders, Stellar will acquire the entire issued share capital of Edesa in exchange for newly-issued Stellar common shares, with Edesa becoming a wholly-owned subsidiary of Stellar (the Exchange). Following the closing of the Exchange, current Stellar shareholders are expected to own approximately 10%, and the current shareholders and option holders of Edesa are expected to own approximately 90%, of the combined company on a fully-diluted basis, subject to a 2% upward or downward adjustment based upon the amount of Stellar's working capital balance on the day before closing.

Liquidity

Company operations have historically been funded by the issuance of common shares, exercise of warrants, grant revenues, contract services revenue and product sales. For the six months ended March 31, 2019 and 2018, the Company reported net losses of $3.1 million and $2.8 million, respectively. As of March 31, 2019, the Company had an accumulated deficit of $53.49 million and working capital of $7.26 million. The Company expects to incur additional losses as it operates its business and pursues additional growth opportunities.

The Company plans to finance company operations over the course of the next twelve months with cash and investments on hand and product sales. Management has flexibility to adjust planned expenditures based on a number of factors including the size and timing of capital expenditures, staffing levels, inventory levels, and the status of customer clinical trials. In light of the proposed share exchange agreement with a third party, management has taken steps to conserve working capital, while maintaining the

Company’s

core competencies, technology and

associated activities

. To help fund its operations and meet its obligations, the Company may also seek additional financing through debt and/or equity financings in the future as and when it considers appropriate, subject to market conditions and the availability of favorable terms.

2.	Basis of Presentation

The accompanying unaudited condensed interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP) for interim financial information and with the instructions to Form 10-Q. They do not include all information and footnotes necessary for a fair presentation of financial position, results of operations and cash flows in conformity with U.S. GAAP for complete financial statements. These condensed interim consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2018.

The accompanying condensed interim consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries, Stellar Biotechnologies, Inc., a California corporation in the U.S. and, prior to March 29, 2019, BioEstelar, S.A. de C.V. a Baja California corporation in Mexico. All significant intercompany balances and transactions have been eliminated in consolidation. All adjustments (consisting of normal recurring adjustments and accruals) considered necessary for a fair presentation of the results of operations for the period presented have been included in the interim period. Operating results for the six months ended March 31, 2019 are not necessarily indicative of the results that may be expected for other interim periods or the fiscal year ending September 30, 2019. The condensed interim consolidated financial data at September 30, 2018 is derived from audited financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2018, as filed on November 30, 2018 with the SEC.

The preparation of financial statements in conformity with U.S. GAAP for interim financial information requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from these estimates.

Functional Currency

The condensed interim consolidated financial statements of the Company are presented in U.S. dollars, unless otherwise stated, which is the Company’s functional currency.

Adoption of Recent Accounting Pronouncements

On October 1, 2018, the Company adopted Accounting Standards Codification (ASC) 606

Revenue Recognition – Revenue from Contracts with Customers

using the modified retrospective method applied to those contracts which were not completed as of this date. Results for reporting periods beginning after October 1, 2018 are presented under ASC Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with the historical accounting under ASC Topic 605. There was no impact to the historical condensed interim consolidated financial statements resulting from the Company’s adoption of ASC Topic 606.

Revenues and accounts receivable are recognized when the promised goods or services are transferred to customers, in an amount that reflects the consideration to which the Company expects to be entitled to in exchange for those goods or services. The Company’s revenue consists of sales of its KLH products, which are recognized upon shipment when the customer obtains control of the product and the Company has no further performance obligations. Deferred revenue is recorded when a customer pays consideration before they obtain control of the product. The Company’s product sales by geographic area are presented in Note 9.

Operating leases

The Company leases buildings and facilities used in its operations under two sublease agreements. In June 2015, the Company exercised its option to extend these sublease agreements for an additional five-year term beginning in October and November 2015. The Company negotiated an option to extend the leases for two additional five-year terms.

The Company leases facilities used for executive offices and laboratories and pays a portion of the common area maintenance. In July 2018, the Company extended this lease for a two-year term, with options to renew for three successive two-year terms.

The Company leased undeveloped land in Baja California, Mexico to assess the potential development of an additional aquaculture locale and expansion of production. In February 2018, the lease was transferred to its subsidiary BioEstelar and the Company has no further obligation under the lease after the sale of its subsidiary on March 29, 2019.

Aggregate future minimum lease payments at March 31, 2019 are as follows:

Year Ending September 30, 2019		92,000
Year Ending September 30, 2020		167,000
Year Ending September 30, 2021		6,000

	$	265,000

Rent expense on these lease agreements amounted to approximately $106,000 and $120,000 for the six months ended March 31, 2019 and 2018, respectively.

Purchase obligations

The Company has commitments totaling approximately $10,000 at March 31, 2019 under signed agreements for leasehold improvements and equipment.

Supply agreements

The Company has commitments under supply agreements with customers for fixed prices per gram of KLH in connection with clinical trials on a non-exclusive basis except within that customer’s field of use. The expiration dates of these supply agreements range from October 2019 to February 2022, and are generally renewable upon written request of the customer.

Joint venture agreement

In May 2016, the Company entered into a joint venture agreement with another party for the formation of a joint venture company to manufacture and sell conjugated therapeutic vaccines. The joint venture is organized as a French simplified corporation. The Company holds a 30% equity interest in the joint venture in exchange for an initial capital contribution of €120,000. One-half of the initial contribution, approximately $67,000, was paid during the year ended September 30, 2016 with the balance due upon the occurrence of certain defined future events. Pursuant to the joint venture agreement, on December 31, 2018, the Company notified the other party that it no longer wished to pursue the project and the parties subsequently agreed to proceed with actions to dissolve and liquidate the joint venture company by mutual consent. Impairment loss of approximately $30,000 is included in general and administrative expenses in the accompanying condensed interim consolidated statements of operations for the six months ended March 31, 2019.

Retirement savings plan 401(k) contributions

The Company sponsors a 401(k) retirement savings plan that requires an annual non-elective safe harbor employer contribution of 3% of eligible employee wages. Contributions to the 401(k) plan were approximately $27,000 and $38,000 for the six months ended March 31, 2019 and 2018, respectively.

Related party commitments

On August 14, 2002, through its California subsidiary, the Company entered into a patent royalty agreement with a director and officer of the Company, whereby he would receive royalty payments in exchange for assignment of his patent rights to the Company. The royalty is 5% of gross receipts from products using this invention in excess of $500,000 annually. The Company’s current operations utilize this invention. There was no royalty expense incurred during the six months ended March 31, 2019 and 2018.

Reverse Share Split

On May 4, 2018, the Company effected a share consolidation (reverse split) of the Company's common shares at a ratio of 1-for-7. As a result of the reverse split, every seven shares of the issued and outstanding common shares, without par value, consolidated into one newly-issued outstanding common share, without par value, after fractional rounding. The number of warrants and options were proportionately adjusted by the split ratio and the exercise prices correspondingly increased by the same split ratio. All shares and exercise prices are presented on a post-split basis in these condensed interim consolidated financial statements.

Black-Scholes option valuation model

The Company uses the Black-Scholes option valuation model to determine the fair value of share-based compensation for placement agent warrants and share options granted. Option valuation models require the input of highly subjective assumptions including the expected price volatility. The Company has used historical volatility to estimate the volatility of the share price. Changes in the subjective input assumptions can materially affect the fair value estimates, and therefore the existing models do not necessarily provide a reliable single measure of the fair value of the Company’s warrants and share options.

Warrants

A summary of the Company’s warrants activity is as follows:

	Number of Warrants			Weighted Average Exercise Price

Balance - September 30, 2017		180,805		$	31.50

Granted		5,665,528			2.68

Share Options

The Company adopted an incentive compensation plan in 2017 (the Incentive Plan), which amended and restated the 2013 fixed share option plan and is administered by the Board of Directors. Options, restricted shares and restricted share units are eligible for grants under the Incentive Plan. The number of shares available for issuance under the Incentive Plan is 228,143, including shares available for the exercise of outstanding options under the 2013 fixed share option plan. No restricted shares or restricted share units have been granted as of March 31, 2019.

The exercise price of an option is set at the closing price of the Company’s common shares on the date of grant.

8.	Fair Value of Financial Instruments

The Company uses the fair value measurement framework for valuing financial assets and liabilities measured on a recurring basis in situations where other accounting pronouncements either permit or require fair value measurements.

Fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The carrying value of certain financial instruments such as accounts receivable, accounts payable, accrued liabilities, and deferred revenue approximates fair value due to the short-term nature of such instruments. Short-term investments in U.S. Treasury Bills are recorded at amortized cost, which approximates fair value.

The Company follows the fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value:

	Level 1:	Quoted prices in active markets for identical or similar assets and liabilities.
	Level 2:	Quoted prices for identical or similar assets and liabilities in markets that are not active or observable inputs other than quoted prices in active markets for identical or similar assets and liabilities.
	Level 3:	Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The Company reports its short-term investments in U.S. Treasury Bills at fair value using Level 1 inputs in the fair value hierarchy.

The following table summarizes fair values for those assets and liabilities with fair value measured on a recurring basis.

	Fair Value Measurements Using
	Quoted Prices in Active Markets for Identical Instruments (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total Fair Value

Concentrations of Credit Risk [Abstract]

Concentration Risk Disclosure [Text Block]

9.	Concentrations of Credit Risk

Credit risk is the risk of an unexpected loss if a customer or third party to a financial instrument fails to meet its contractual obligations. Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash and cash equivalents, U.S Treasury Bills, and accounts receivable. The Company estimates its maximum credit risk at the amount recorded on the balance sheet.

Management’s assessment of the Company’s credit risk for cash and cash equivalents is low as they are held in major financial institutions believed to be credit worthy or U.S. Treasury Bills with maturities of 90 days or less. The Company limits its exposure to credit loss for short-term investments by holding U.S. Treasury Bills with maturities of 1 year or less. Based on credit monitoring and history, the Company considers the risk of credit losses due to customer non-performance on accounts receivable to be low.

The Company had the following concentrations of revenues by customers, each of which accounted for more than 10% of revenues in the applicable period:

- Definition

Tabular disclosure of warrants or rights issued. Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.
