Equity Financing

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 is not obligated, to issue and sell Common Shares in the capital of the Company (each a “Common Share”) through Wainwright (the “ATM Program”). The ATM Agreement was refreshed in November 2024 to allow for aggregate sales proceeds of up to $8,000.

During the three months ended March 31, 2025, the Company realized net proceeds of $269 under the ATM Program. During the three months ended March 31, 2024, the Company realized net proceeds of $53 under the ATM Program, which were settled in April 2024. As of March 31, 2025, $7,506 remained available under the ATM Program.

Stock-Based Compensation

The Company’s active stock-based compensation plans include restricted share units (“RSUs”) issuable pursuant to the Company’s long-term equity incentive plan and deferred share units (“DSUs”) issuable pursuant to the Company’s deferred share unit plan (“DSU Plan”). The Company's stock option plan remains in place, however no new issuances can be made at this time. 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 particular time. Stock-based compensation 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.

As of March 31, 2025, unrecognized compensation expense for RSUs was $658, which is expected to be recognized over a weighted average period of 1.7 years.

During the three months ended March 31, 2025 and 2024, the Company withheld Common Shares with an equivalent value to meet employee withholding tax obligations of $245 and $85, respectively, which resulted from the vesting of RSUs during these periods.

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 when the non-employee director ceases to be a director of the Company. During the three months ended March 31, 2025, the Board granted 364,000 DSUs and the Company recognized $251 in DSU expense. During the three months ended March 31, 2024, the Board granted 612,000 DSUs and the Company recognized $208 in DSU expense.
