Although YSS believes that the expectations and assumptions on which the forward-looking statements are based are reasonable, undue reliance should not be placed on the forward-looking statements because YSS can give no assurance that they will prove to be correct. Since forward-looking statements address future events and conditions, by their very nature they involve inherent risks and uncertainties. Actual results could differ materially from those currently anticipated due to a number of factors and risks. These include, but are not limited to: the COVID-19 pandemic, governmental responses thereto and the impact thereof on the global economy, capital markets, the cannabis retail industry and the Company; success of the operations of the Company; abil ity of the Company to execute its business strategy and future plans of operations; availability of cannabis, cannabis products and cannabis accessories; supply interruption or delays; timing or delays of permitting and licensing processes; federal, provincial and municipal government cannabis regulation and changes thereto; increases in taxes and changes in government regulations; development of new retail stores including construction delays; increased competition for, among other things, capital, cannabis products, cannabis accessories, retail licenses and permits, development permits and authorizations, leases, services, customers and skilled personnel; risks related to product liability, product recalls and health and safety; labour costs, shortages and labour relations; timing and amount of capital and other expenditures; the effect of any future litigation proceedings on the Company’s business; negative studies or reports published in relation to the use of cannabis, cannabis products or cannabis accessories; unfavourable publicity and consumer perception with respect to cannabis, cannabis products and cannabis accessories; third party credit risks; risks related to cybersecurity and intellectual property; and other factors more fully described from time to time in the reports and filings made by the Company with securities regulatory authorities.

Readers are cautioned that the assumptions used in the preparation of forward-looking information, although considered reasonable at the time of preparation, may prove to be imprecise. YSS’s actual results, performance or achievement could differ materially from those expressed in, or implied by, these forward-looking statements and accordingly there can be no assurance that such expectations will be realized and/or what benefits YSS will derive therefrom. The forward-looking information contained in this presentation is made as of the date hereof and YSS undertakes no obligation to update or revise any forward-looking information, whether as a result of new information, future events or otherwise, unless required by applicable securities laws. The forward-looking information contained in this presentation is expressly qualified by this cautionary statement.

FOFI Disclosure. This presentation contains future-oriented financial information and financial outlook information (collectively, “FOFI”) about the Company’s store-level EBITDA, revenue, gross margin and components thereof, all of which are subject to the same assumptions, risk factors, limitations and qualifications as set forth in the above paragraphs. FOFI contained in this presentation was approved by management as of the date of this presentation and was provided for the purpose of providing further information about YSS’s anticipated future business operations. YSS disclaims any intention or obligation to update or revise any FOFI contained in this presentation, whether as a result of new information, future events or otherwise, unless required pursuant to applicable law.

Non-IFRS Measures. Certain financial measures referred to in this presentation, such as enterprise value and store-level EBITDA, are not prescribed by International Financial Reporting Standards (“IFRS”). YSS uses these measures to help evaluate its financial, operating performance, liquidity and leverage. These non-IFRS financial measures do not have any standardized meaning prescribed by IFRS and therefore may not be comparable to similar measures presented by other issuers. Enterprise value is calculated by multiplying the closing common share price as of a particular date by the total number of common shares outstanding and adding total debt (excluding discounts and debt transaction costs). This measure, in combination with other measures, is used by the investment community to assess the overall market value of the business. Store-Level EBITDA is calculated as revenue less cost of goods sold and operating costs before IFRS-16 capitalized costs and before corporate general & administrative expenses. Corporate EBITDA is calculated as Store-Level EBITDA less corporate general & administrative costs.

Not an Offer. This presentation does not constitute an offer to sell or solicitation of an offer to buy any of the securities described herein. The sole purpose of this presentation, in paper or electronic form, is strictly for information purposes.

U.S. Registration. This presentation is not an offer of the securities for sale in the United States. The securities have not been registered under the U.S. Securities Act of 1933, as amended, and may not be offered or sold in the United States absent registration or an exemption from registration. This presentation shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the securities in any state in which such offer, solicitation or sale would be unlawful.

Sales & Profitability Growth - 2020 YTD

Revenue Gross Margin Store-Level EBITDA Store Count

TARGET TO EXIT 2020 WITH POSITIVE RUN-RATE CORPORATE EBITDA1

• Due to fixed cost nature of operating costs and corporate G&A expenses, same-store sales growth drives exponential growth in EBITDA1 and profitability.

• Year-to-date 2020 growth is principally attributable to same-store sales growth.

• Q2 2020 store-level EBITDA1 (prior to corporate G&A expenses) grew 131% over Q1 2020 on 12% revenue growth over the same period.

• Q2 2020 G&A expenses averaged $224,000 / month.

• Increased store-level EBITDA1 margin from 4% in Q1 2020, to 8% in Q2 2020 and expect to exceed 10% in Q3 2020.

• Decreased monthly operating costs to less than $30,000 per store. At 30% gross margin, the average break-even revenue per store is $100,000 / month (or $1.2 million / year).

• G&A expenses were $671,000 in Q2 2020, $149,000 (18%) lower than in Q1 2020

• Limited incremental G&A expense required to capture new-store or same-store growth will drive further corporate efficiencies or synergies in strategic acquisitions
