Equity Financing

​

During July 2021, we closed a public offering of 12,272,730 units (the “Units”) for net proceeds of $12,323 (the “2021 Offering”). The stock issuance costs associated with the 2021 Offering were $1,177. Each Unit consisted of one common share of the Company (each a “Common Share”) and one-half of one Common Share purchase warrant (each full warrant, a “Warrant”). A total of 7,408,101 Warrants were issued, including 920,454 Warrants purchased by the underwriters pursuant to an overallotment option and 351,282 broker Warrants issued to the underwriters as compensation. Each Warrant entitles the holder thereof to purchase one Common Share at a price of $1.25 per Common Share (subject to adjustment in certain circumstances) and is exercisable for a period of 36 months from the closing of the 2021 Offering. The Warrants, which are classified as equity, had an aggregate relative fair value of $1,991 upon the issuance thereof on the closing date. The relative fair value of Warrants was estimated at the grant date using the Black-Scholes option pricing model using the following assumptions: 1) expected volatility of 70.6%, 2) risk-free rate of 0.43%, 3) contractual term of 3 years, and 4) stock price on the closing date of $0.89 per Common Share. A relative fair value of $11,509 was allocated to the Common Shares.

​

Vista is party to an at-the-market offering agreement (the “ATM Agreement”) with H. C. Wainwright & Co., LLC (“Wainwright”), under which the Company has the right, but was not obligated, to issue and sell Common Shares through

Wainwright for aggregate sales proceeds of up to $10,000 (the “ATM Program”). No securities can be offered in Canada under the ATM Agreement. As of December 31, 2022, $9,748 remained available under the ATM Program.

​

During the year ended December 31, 2022 the Company sold 401,884 Common Shares for net proceeds of $244 under the ATM Program. During the year ended December 31, 2021 the Company sold 798,270 Common Shares for net proceeds of $871 under the ATM Program, which excluded $191 that settled for cash in January 2021. 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.

​

Other Share Issuances

​

During the years ended December 31, 2022 and 2021 we issued 889,762 and 946,328 Common Shares, respectively, in connection with vesting of restricted share units (“RSUs”).

​

Warrants

​

Warrant activity is summarized in the following table. Intrinsic value is the aggregate value of warrants that were in the money at the end of the period. The warrants are subject to standard anti-dilution provisions.

​

Stock-Based Compensation

​

The Company’s stock-based compensation plans include: RSUs currently outstanding under 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 of Directors”), with vesting provisions as determined by the Board of Directors.

​

Stock-based compensation expense for the years ended December 31, 2022 and 2021 was:

​

​	​	​	​	​	​	​	​
​	​	Year Ended December 31,					​

​	​	​	​	​	​	​	​
Phantom units	​	$	—	​	$	26	​

​

As of December 31, 2022, unrecognized compensation expense for RSUs was $297, which is expected to be recognized over a weighted average period of 1.2 years.

Restricted Share Units

The following table summarizes RSU activity:

​

​	​	​	​	​	​	​
​	​	​	​	Weighted Average		​

Unvested - December 31, 2022	​	1,472,008	​	$	0.60	​

​

During the years ended December 31, 2022 and 2021, the Company withheld shares equivalent to the value of employee withholding tax obligations which resulted from RSUs vesting in the period. Shares withheld are considered cancelled/forfeited.

​

Under the LTIP, a portion of the RSU awards vest on a fixed future date providing the recipient continues to be affiliated with Vista on that date. Other RSU awards vest subject to achievement of certain performance and market criteria, including the accomplishment of certain corporate objectives and the Company’s share price performance. Of the unvested RSUs, approximately 43% will vest based on fixed future dates, and approximately 57% will vest on share-price criteria. The minimum vesting period for RSUs is one year.

​

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 March 2022, the Board of Directors granted 324,000 DSUs and the Company recognized $272 of DSU expense. In February 2021, the Board of Directors granted 204,000 DSUs and the Company recognized $212 of DSU expense.

​

The following table summarizes DSU activity:

Phantom Units

​

The value of each phantom unit is equal to the Company’s share price on the vesting date and is payable in cash. Phantom units vest on fixed future dates provided the recipient continues to be affiliated with Vista on those dates. The Company accounts for these units as awards classified as liabilities. The Company recognized $26 of compensation expense for these units in the year ended December 31, 2021. The Company paid $65 for phantom units which vested during the year ended December 31, 2021.

​

A summary of unvested phantom units is set forth in the following table:

​

​	​	​	​	Weighted Average	​

Diluted Common Shares	​	118,005,490	​	110,263,237	​

​

Unvested RSUs representing 1,472,008 Common Shares, stock options to purchase 1,367,000 Common Shares, warrants to purchase 7,408,101 Common Shares, and vested DSUs representing 1,254,000 unissued Common Shares were

outstanding at December 31, 2022 but were not included in the computation of diluted weighted average Common Shares outstanding because their effect would have been anti-dilutive.
