Compensation Actually Paid vs. Total Shareholder Return
Compensation Actually Paid and Cumulative TSR
As shown in the following graph, the compensation actually paid to the PEOs and the average amount of compensation actually paid to our non-PEO NEOs as a group (excluding the PEOs) during the periods presented do not have significant correlation given that a significant portion of their compensation is in the form of long-term equity awards. However, equity awards values are significantly impacted by changes in our stock price each period. These equity awards strongly align our executive officers’ interests with those of our stockholders by providing a continuing financial incentive to maximize long-term value for our stockholders and by encouraging our executive officers to continue in our employment for the long-term.

Compensation Actually Paid vs. Net Income
Compensation Actually Paid and Net Income (Loss) 
Our company has not historically looked to net income (loss) as a performance measure for our executive compensation program. Our net income (loss) was approximately $(13.6) million in 2022, $(12.5) million in 2023, and $3.6 million in 2024.
   
Total Shareholder Return Amount $ (30) (85) (94)
Net Income (Loss) $ 3,595 (12,514) (13,584)
Additional 402(v) Disclosure Cumulative TSR reported in column (f) is calculated by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between
our company’s share price at the end and the beginning of the measurement period by our company’s share price at the beginning of the measurement period. No dividends were paid on stock or option awards in 2022, 2023 or 2024.

(6)The dollar amounts reported in column (g) represent the amount of net loss reflected in our consolidated audited financial statements for the applicable year.
