| A. | New Issuance of $5 Million Debenture Adjustment |
As part of its strategic financial restructuring, Sono Group N.V. has entered into a Securities Purchase Agreement with Yorkville to issue a new secured convertible debenture with a principal amount of $5.0 million, subject to Nasdaq approving the Company’s requested uplisting to Nasdaq Capital Markets. Yorkville had advanced $2.0 million (1.9M Euros) of the $5.0 million as of 3/31/25, an additional $500k (462k Euros) was received on 4/24/25 with $2.5 million (2.387M Euros) still subject to Nasdaq Approval. In the cash section it reflects 462k Euros plus 2.387M Euros totaling 2.849M left as the company received $2M already as advances in Q1 2025 already reflected in the 3/31/25 balance sheet.
| B. | Conversion of all existing debt to preferred equity |
Sono Group N.V. signed an Exchange Agreement with Yorkville to convert the newly issued debenture, along with all other existing outstanding convertible debentures, into preferred equity. The total debt being exchanged amounts to approximately €37.8 million, including the €32.7 million of previously issued convertible debentures and the €5.0 million new debentures. Under the agreement, this notes payable will be converted into 1,242 newly issued preferred shares, each with a nominal value of €300. These shares are convertible into 30,000 ordinary shares post-implementation of the reverse stock split.
| C. | Changes to the fair value in Convertible Notes Payable |
The income from changes in fair value of convertible notes payable carried at Fair value of 19,653 is reversed as part of the exchange agreement when the actual value of the total convertible notes payable plus accrued interest is all converted to preferred equity.
| D. | Change in Subscribed Capital |
Change in subscribed capital is due to reverse split of 75 to 1 along with change in nominal value of ordinary and high voting shares.
| E. | Net Equity Converted to US Dollars |
Net Equity of 4.31M Euros is converted to $4.66M at an exchange rate as of the date as of 3/31/25 of 1.0815 from Euros to US Dollars.
