Equity Financing

Vista is a party to an at-the-market offering agreement (the “ATM Agreement”) with H. C. Wainwright & Co., LLC (“Wainwright”), under which the Company may, but is not obligated to, issue and sell common shares in the capital of the Company (each a “Common Share”) through Wainwright for aggregate sales proceeds of up to $10,000 (the “ATM Program”). No securities will be offered in Canada under the ATM Agreement. The ATM Agreement was amended in June 2020 to remain in force until terminated by either party. During the three and six months ended June 30, 2021 the Company sold 392,470 and 798,270 Common Shares, respectively, under the ATM Program for net proceeds of $437 and $871, respectively. During the three and six months ended June 30, 2020 the Company sold 1,031,819 Common Shares under the ATM Program for net proceeds of $807. Each sale under the ATM Agreement was made pursuant to an “at the market offering” as defined in Rule 415 under the United States Securities Act of 1933, as amended. In July 2021, the ATM Program was suspended. Vista has the right to use the ATM Program in the future following filing and effectiveness of a new shelf registration statement with the Securities and Exchange Commission.

Stock-Based Compensation

The Company’s stock-based compensation plans include: restricted share units (“RSUs”) issuable pursuant to the Company’s long-term equity incentive plan (“LTIP”), deferred share units (“DSUs”) issuable pursuant to the Company’s deferred share unit plan (“DSU Plan”) and stock options (“Stock Options”) issuable under the Company’s stock option plan (the “Plan”). Stock-based compensation may be issued to our directors, officers, employees and consultants. The maximum number of Common Shares that may be reserved for issuance under the combined stock-based compensation plans is a variable number equal to 10% of the issued and outstanding Common Shares on a non-diluted basis at any one time. Vista also issued phantom units in 2018 to be settled in cash over a three-year term. Stock-based compensation and phantom units may be granted from time to time at the discretion of the Board of Directors of the Company (the “Board”), with vesting provisions as determined by the Board.

During the six months ended June 30, 2021 and 2020, the Company withheld Common Shares with an equivalent value to meet employee withholding tax obligations of $396 and $97, respectively, that resulted upon vesting of RSUs during the period. Common Shares withheld are considered cancelled/forfeited.

Deferred Share Units

The DSU Plan provides for granting of DSUs to non-employee directors. DSUs vest immediately, however the Company will issue one Common Share for each DSU only after the non-employee director ceases to be a director of the Company. In February 2021, the Board granted 204,000 DSUs and the Company recognized $212 in DSU expense. In March 2020, the Board granted 360,000 DSUs and the Company recognized $209 in DSU expense.
