In addition, management evaluated the Series A Preferred Stock after the modifications and determined that they should be reclassified to mezzanine equity under ASC 480-10-S99 as a result of the Company not having sufficient authorized and unissued shares to settle a conversion to Common Stock.

On July 19, 2024, the shareholders of the Company approved an amendment to the Company’s Fourth Amended and Restated Articles of Incorporation (the “Articles of Incorporation”) to increase the number of authorized shares of common stock and as a result the Company had sufficient authorized and unissued shares to settle a conversion to common stock. Accordingly, the Series A Preferred Stock was reclassified to permanent equity at the date of the event that caused the reclassification. See description of Series C Preferred Stock issued in exchange for the then outstanding Series A Preferred Stock and PIPE Warrants.

On September 9, 2024, as a result of the issuance of the First Amended Conduit Note (see Note 9, “Commitments and Contingencies,” for further details), the adjustment provisions in the Series A Preferred Stock were triggered and caused certain adjustments in the currently effective conversion price of the Series A Preferred Stock. The Company recognized the effect of the down round feature triggered on September 9, 2024 as the difference between: (1) the fair value of the Series A Preferred Stock using the pre-trigger conversion price, and (2) the fair value of the Series A Preferred Stock using the reduced conversion price. The value of the effect of the down round feature of $3,464,426 was recognized as a deemed dividend in the year ended December 31, 2024 that reduced APIC and income available to common shareholders in calculating earnings per share.

Warrants

In September 2021, the Company entered into transactions with holders of its outstanding Series A Preferred Stock to issue PIPE Warrants to purchase the Company's common stock. The Company’s outstanding PIPE Warrants have anti-dilution provisions that would increase the number of shares issuable upon exercise and lower the exercise price of the PIPE Warrants if the Company issues equity securities at a price less than the current exercise price of the PIPE Warrants at the time of such issuance. Pursuant to the Waiver, investors agreed to a floor of $22.50 ($0.14 prior to the Reverse Stock Splits) with respect to the anti-dilution adjustments in the warrants and extend the term of the warrants until March 28, 2029.

The PIPE Warrants were valued immediately before and immediately after the modifications to calculate the $10.6 million incremental value of the modified PIPE Warrants. The Company considered this incremental value to be a deemed dividend that reduced income available to common shareholders in calculating earnings per share.

Management evaluated the warrants after the modifications made in February 2024 and determined that they should be reclassified from equity to liability based on the guidance in ASC 815-40 and the Company failing to have enough authorized and unissued shares available to settle an exercise of the contract. In accordance with ASC 815-40, the carrying value of the warrants were adjusted to fair value through an adjustment in stockholders’ equity immediately prior to the reclassification. Subsequent to the reclassification, management remeasured the warrant liability to fair value and recorded the change in fair value to other income (expense) in the consolidated statement of operations.

On July 19, 2024, the shareholders of the Company approved an amendment to the Articles of Incorporation to increase the number of authorized shares of common stock and as a result the Company had sufficient authorized and unissued shares to settle an exercise of the contract. Accordingly, management determined that the warrants should be reclassified to equity. In accordance with the guidance in ASC 815-40-35-10, management remeasured the warrant liability to fair value immediately before the reclassification and recorded the change in fair value to other income (expense) in the consolidated statement of operations.

On September 9, 2024, as a result of the issuance of the First Amended Conduit Note (see Note 9, “Commitments and Contingencies,” for further details), the adjustment provisions in the warrants were triggered and caused certain adjustments in the currently effective exercise price of the warrants and a proportional increase in the amount of shares of common stock issuable under the warrants. The Company recognized the effect of the down round feature triggered on September 9, 2024 as the difference between: (1) the fair value of the warrants using the pre-trigger conversion price, and (2) the fair value of the warrants using the reduced conversion price. The value of the effect of the down round feature of $875,737 was recognized as a deemed dividend in the year ended December 31, 2024 that reduced income available to common shareholders in calculating earnings per share.

On September 9, 2024, the Company entered into a Securities Exchange Agreement with the holders of the Series A Preferred Stock and PIPE Warrants to cancel and retire the Series A Preferred Stock and PIPE Warrants in exchange for shares of Series C Convertible Preferred Stock of the Company (the “Series C Preferred Stock”). The Company determined that the exchange of the Series A Preferred Stock and warrants for the Series C Preferred Stock resulted in the extinguishment of the Series A

Preferred Stock and warrants. As a result, the difference between the carrying amount of the Series A Preferred Stock and warrants and the fair value of the Series C Preferred Stock of $4,075,681 was recognized as a deemed contribution in the year ended December 31, 2024 that increased APIC and income available to common shareholders in calculating earnings per share.

Series C Preferred Stock

On September 9, 2024, the Company’s board of directors authorized the issuance of up to 35,000 shares of Series C Preferred Stock. As a result of the exchange noted above, the Company issued 28,041 shares of Series C Preferred Stock. Each share of Series C Preferred Stock is convertible, at any time after issuance and at the option of the holder subject to certain beneficial ownership limitations, into a number of shares of common stock determined by dividing the Stated Value of such share by the Conversion Price. The Stated Value per share of Series C Preferred Stock is $1,000.00 and the Conversion Price per share of Series C Preferred Stock is $22.50 ($0.45 prior to the October Reverse Stock Split). The Series C Preferred Stock does not contain any of the price resets set forth in the Series A Preferred Stock, except in the case of stock splits, recapitalizations and similar transactions by the Company. During 2024, all 28,041 shares of Series C Preferred Stock were converted into 1,246,262 shares of common stock. As of December 31, 2024, there were no shares of Series C Preferred Stock outstanding.

The holders of Series C Preferred Stock were entitled to vote exclusively with respect to a proposal submitted to the Company’s shareholders at a meeting of shareholders to be held by the Company to approve the changing of the Company’s state of incorporation from the State of Minnesota to the State of Delaware together as a single class with the common stock on an as-converted basis, subject to the beneficial ownership limitations, as follows: each share of Series C Preferred Stock shall be entitled to such number of votes equal to the quotient obtained by dividing: (i) the Stated Value by (ii) $39.573 ($0.79146 prior to the Reverse Stock Splits). As long as any shares of Preferred Stock are outstanding, the Company shall not, without the affirmative vote of the holders of a majority of the then outstanding shares of Series C Preferred Stock, (a) alter or change adversely the powers, preferences or rights given to the Series C Preferred Stock or alter or amend the Certificate of Designation, (b) authorize or create any class of stock ranking as to redemption senior to the Series C Preferred Stock, (c) amend its articles of incorporation or other charter documents in any manner that adversely affects any rights of the holders of the Series C Preferred Stock, (d) increase the number of authorized shares of the Company’s preferred stock, or (e) enter into any agreement with respect to any of the foregoing. The holders of Series C Preferred Stock are not entitled to voting rights except for the foregoing and to the extent required by law.

Series B Preferred Stock

On May 13, 2024, the Company entered into a Subscription and Investment Representation Agreement pursuant to which the Company agreed to issue and sell one share of the Company’s Series B Preferred Stock, par value $1.00 per share (“Series B Preferred Stock”), for $15. The sale closed on May 14, 2024.

On May 13, 2024, the Company filed a certificate of designation (the “Certificate of Designation”) with the Secretary of State of Minnesota, effective as of May 13, 2024, designating the rights, preferences, privileges and restrictions of the share of the Series B Preferred Stock. The Certificate of Designation provides that the share of Series B Preferred Stock has 5,000,000,000 votes and will vote together with the outstanding shares of the Company’s common stock as a single class exclusively with respect to (i) any proposal to amend the Company’s Articles to effect a reverse stock split of the Company’s common stock (the “Reverse Stock Split Proposal”) and (ii) any proposal to adopt an amendment to the Articles, or any other proposal to otherwise approve or ratify, to increase the authorized number of shares of common stock, either by increasing the total number of authorized shares or by effecting a reverse stock split without a corresponding decrease in the number of authorized shares (the “Authorized Shares Increase Proposal”). The Series B Preferred Stock will also be entitled to vote in the election of directors, but will only have one vote to cast with respect to each director nominee.

Under the Certificate of Designation, the outstanding share of Series B Preferred Stock will be cancelled in whole, but not in part, at any time (i) if such cancellation is ordered by the Company’s board of directors in its sole discretion or (ii) automatically upon the approval by the Company’s shareholders of the Reverse Stock Split Proposal and Authorized Shares Increase Proposal at any meeting of shareholders. The holder of the share of Series B Preferred Stock was not entitled to any consideration upon such cancellation. The shareholders approved the Reverse Stock Split Proposal and Authorized Shares Increase Proposal on July 19, 2024 and, as a result, the share of Series B Preferred Stock was automatically cancelled at that time.

Registered Direct Offering

On February 5, 2024, the Company entered into a securities purchase agreement with certain institutional investors for the sale by the Company of 3,604 shares (2,702,703 prior to the Reverse Stock Splits) of the Company’s common stock in a registered direct offering. The purchasers in this offering purchased, and the Company sold, the shares at a purchase price per share of
