Explanatory Note

This Amendment No. 1 on Form 8-K/A (this “Amendment”)

amends the Current Report on Form 8-K filed by Sono Group N.V. (the “Company”) with the U.S. Securities and Exchange Commission

on March 19, 2026 (the “Original Current Report”), relating to events occurring on March 14, 2026. This Amendment is filed

to (i) report the Company’s entry into, and consummation of, a Share Purchase and Transfer Agreement effecting the sale of the

Company’s entire interest in its wholly-owned subsidiary Sono Motors GmbH, and (ii) supplement and update Item 2.05 of the Original

Current Report with respect to costs and charges associated with the exit from the Company’s legacy solar operations, as contemplated

by the Original Current Report. Except as set forth herein, the Original Current Report is not amended or otherwise modified.

Item 1.01 Entry into a Material Definitive Agreement.

On May 4, 2026 (the “Signing Date”),

the Company entered into a Share Purchase and Transfer Agreement (the “SPA”) with (i) Vorratsla-160 M UG (haftungsbeschränkt),

a German limited liability company whose sole shareholder is Denis Azhar, and (ii) Vorratsla-161 M UG (haftungsbeschränkt), a German

limited liability company whose sole shareholder is Jan Schiermeister (together, the “Purchasers”), and Sono Motors GmbH,

a German limited liability company (“Sono Motors”). Denis Azhar and Jan Schiermeister are the current managing directors

of Sono Motors. The SPA was notarized under German law on the Signing Date.

Sale and Transfer of Shares. Pursuant to

the SPA, the Company sold and transferred to the Purchasers, with immediate legal effect in rem (abtreten mit dinglicher Wirkung)

under German law and without conditions precedent, all 33,588 shares representing 100% of the outstanding share capital of Sono Motors

(the “Sold Shares”), with 50% of the Sold Shares transferred to each Purchaser. The purchase price for the Sold Shares was

€1.00 in the aggregate.

Sale and Assignment of Shareholder Loan Repayment

Claim. Simultaneously, the Company sold and assigned to the Purchasers, with immediate legal effect under German law, the Company’s

repayment claims (including accrued interest) under shareholder loans previously extended by the Company to Sono Motors (the “Shareholder

Loan Repayment Claim”). The outstanding amount of the Shareholder Loan Repayment Claim was approximately €10.5 million as

of April 29, 2026. The purchase price for the Shareholder Loan Repayment Claim was €1.00 in the aggregate, with 50% of the Shareholder

Loan Repayment Claim assigned to each Purchaser. Each Purchaser’s portion of the Shareholder Loan Repayment Claim is subject to

(i) a standstill undertaking by the Purchasers that they will not demand, enforce or otherwise seek repayment, whether fully or partly,

of the Shareholder Loan Repayment Claim for a period of two years following the Signing Date, and (ii) a qualified subordination (qualifizierter

Rangrücktritt) pursuant to German insolvency law under which the Shareholder Loan Repayment Claim is subordinated to all other

present and future creditors of Sono Motors.

Ancillary Matters. In connection with the

SPA, the Company and Sono Motors agreed to terminate the Corporate Services Agreement between them, pursuant to which Sono Motors had

provided certain accounting, controlling, treasury and regulatory reporting services to the Company, with retroactive effect as of April

30, 2026. The SPA also requires the parties to use their best efforts to cause the lease agreement for the premises located at Waldmeisterstraße

93, 80935 Munich, Germany, under which the Company is the current lessee, to be transferred to Sono Motors as lessee by no later than

June 30, 2026, with a full release of the Company from any further liability thereunder; if such transfer is not completed by that date,

the Company has the right to terminate the lease agreement. In addition, Sono Motors granted the Company a worldwide, limited, non-exclusive,

non-transferable, royalty-free, irrevocable license to use the “Sono” brand as company name and in connection with its stock

exchange listing, securities trading or stock ticker.

Following the Signing Date, the Company no longer

holds any equity interest in, or exercises any control over, Sono Motors. The SPA is governed by the laws of Germany, and disputes arising

under the SPA are subject to binding arbitration in Munich, Germany.

The foregoing description of the SPA does not purport

to be complete and is qualified in its entirety by reference to the full text of the SPA, a copy of which is filed as Exhibit 10.1 to

this Amendment and incorporated herein by reference.

Item 2.01 Completion of Acquisition or Disposition

of Assets.

The information set forth under Item 1.01 of this

Amendment is incorporated herein by reference.

Item 2.05 Costs Associated with

Exit or Disposal Activities.

This Item amends and supplements Item 2.05 of the

Original Current Report.

As previously disclosed in the Original Current

Report, on March 14, 2026, the supervisory board of the Company resolved to terminate all current and future funding commitments to Sono

Motors and to exit the legacy solar operations conducted through Sono Motors, with immediate effect (the “Exit”). In the

Original Current Report, the Company stated that it was unable to make a good faith estimate of the total costs and charges that may

be incurred in connection with the Exit and committed to amend the Original Current Report when such amounts became reasonably estimable.

As described in Item 1.01 of this Amendment, the Company has now completed the Exit through the execution and consummation of the SPA

on the Signing Date.

In connection with the Exit and the transactions

contemplated by the SPA, the principal costs the Company has incurred and expects to continue to incur consists of legal, advisory and

other professional fees and expenses associated with the Exit. The Company does not currently expect to incur any additional material

exit or disposal charges. The Company does not expect to receive any material net proceeds from the Exit. Any costs incurred in connection

with the Exit are expected to be reduced by cash flow to the Company from the Treasury Strategy.

Item 8.01 Other Events.

On May 8, 2026, the Company issued a press

release regarding the completion of its exit from the Company’s legacy solar business. A copy of that press release is filed as

Exhibit 99.1 to this Current Report and is incorporated herein by reference.

As previously disclosed, the Company intends to

solicit the ratification by its shareholders of the engagement by the Company in the Treasury Strategy.

Forward Looking Statements

This Current Report contains certain “forward-looking

statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933,

as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Such forward-looking statements include, but are not

limited to, statements regarding the consummation of transactions as part of the Treasury Strategy, including their timing and the expected

cash flow and the use of proceeds therefrom; the receipt of any required shareholder approvals; the projected operational and financial

performance of the Company and its subsidiaries, including the Company following implementation of the Treasury Strategy; the Company’s

product offerings and developments and business plans; and the Company’s expectations, hopes, beliefs, intentions, plans, prospects

or strategies regarding the future revenue and the business plans of the Company’s management team, including the pursuit of the

Treasury Strategy. Any statements contained herein that are not statements of historical fact may be deemed to be forward-looking

statements. In addition, any statements that refer to projections, forecasts, or other characterizations of future events or circumstances,

including any underlying assumptions, are forward-looking statements. The words “anticipate,” “believe,” “contemplate,”

“continue,” “could,” “estimate,” “expect,” “intends,” “may,”

“might,” “plan,” “possible,” “potential,” “predict,” “project,”

“seek,” “should,” “will,” “would” and similar expressions may identify forward-looking

statements, but the absence of these words does not mean that a statement is not forward-looking. The forward-looking statements contained

in this Current Report are based on certain assumptions and analyses made by the management of the Company considering their respective

experience and perception of historical trends, current conditions, and expected future developments and their potential effects on the

Company as well as other factors they believe are appropriate in the circumstances. There can be no assurance that future developments

affecting the Company will be those anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which

are beyond the control of the parties), or other assumptions that may cause actual results or performance to be materially different

from those expressed or implied by these forward-looking statements, including the consummation and timing of any transactions as part

of the Treasury Strategy, and the cash flow to the Company therefrom; the occurrence of any uncured event of default or any event, change

or other circumstance that could give rise to the termination of the Company’s ISDA Master Agreement relating to the Treasury Strategy;

the outcome of any legal proceedings that may be instituted against the Company; risks associated with the Treasury Strategy replacing

the former plans and operations of the Company including the legacy solar operations; potential difficulties in employee retention as

a result of the Treasury Strategy; whether the Company will be able to maintain compliance with the continued listing standards of The

Nasdaq Stock Market LLC or comply with the initial listing standards of another national securities exchange; the ability of the Company

to service or otherwise pay its debt obligations; market acceptance of the Company’s product offerings; that the Company will have

sufficient capital to operate as anticipated; the demand for the Company’s products; and global supply chains and legislative,

regulatory and economic developments in general. Should one or more of these risks or uncertainties materialize or should any of the

assumptions being made prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements.

The Company undertakes no obligation to update or revise any forward-looking statements, whether because of new information, future events,

or otherwise, except as may be required under applicable securities laws.

Additional Information and Where to Find It

In connection with the solicitation of the ratification

by the Company’s shareholders of the engagement by the Company in the Treasury Strategy, the Company intends to file with the Securities

and Exchange Commission (the “SEC”) a proxy statement on Schedule 14A (the “Proxy Statement”) relating to an

extraordinary general meeting of the Company’s shareholders to be held for the purpose of ratifying the Company’s engagement

in the Treasury Strategy (the “Special Meeting”). This Current Report is not a substitute for the Proxy Statement or any

other document that the Company may file with the SEC or send to the Company’s shareholders in connection with the Special Meeting.

This Current Report does not contain all of the information that should be considered in respect of the matters to be noticed for the

Special Meeting in the Proxy Statement, and additional information will be set forth in the Proxy Statement when it becomes available.

Shareholders of the Company are urged to read all relevant documents filed with the SEC, including the Proxy Statement, as well as any

amendments or supplements to these documents, carefully when they become available. Promptly after filing its definitive Proxy Statement

with the SEC, the Company will mail the definitive Proxy Statement and a proxy card to each shareholder of the Company entitled to vote

at the Special Meeting as of a record date to be established for voting at the Special Meeting.

Shareholders may also obtain a copy of the Proxy

Statement, as well as other documents filed by the Company with the SEC without charge, at the SEC’s website located at www.sec.gov.

In addition, shareholders may obtain a free copy of the Company’s filings with the SEC from the Company’s website at https://ir.sonomotors.com/.

Participants in the Solicitation

The Company and its directors, executive officers,

employees and other persons may be deemed to be participants in the solicitation of proxies from the Company’s shareholders in

connection with the Special Meeting under SEC rules. Shareholders may obtain more detailed information regarding the names, affiliations

and interests of the Company’s executive officers and directors in the solicitation by reading the Company’s Annual Report

on Form 10-K for the fiscal year ended December 31, 2025, as filed with the SEC on April 1, 2026 and the Proxy Statement when

it becomes available.

This Current Report shall not constitute a solicitation

of a proxy, consent or authorization with respect to any securities or in respect of the matters to be noticed in the definitive Proxy

Statement when it becomes available.

Preamble

A. The Company is a German limited liability company (Gesellschaft mit beschränkter Haftung),

with its business address at Waldmeisterstraße 93, 80925 Munich, Germany, registered with the commercial register of the local court

(Amtsgericht) of Munich under HRB 224131.

B. The Company’s activities are focused on integrating proprietary solar technology onto vehicles.

C. The Seller is the sole shareholder of the Company. The Seller intends to sell all of its shares in the

Company and to discontinue its involvement in the business of the Company and any current or future commitments to the Company.

1

D. Denis Azhar, the sole shareholder of Purchaser 1, and Jan Schiermeister, the sole shareholder of Purchaser

2, are currently the managing directors of the Company.

E. The Company has a registered share capital of EUR 33,588.00 (in words: thirty-three thousand five

hundred and eighty-eight euros), divided into 33,588 (in words: thirty-three thousand five hundred and eighty-eight) shares with the consecutive

numbers 1 to 33,588 held by the Seller (the "Shares").

F. The Seller has granted several unsecured, interest-bearing shareholder loans in the total nominal amount

of EUR 9,806,000.00 (in words: nine million eight hundred and six thousand euros) to the Company (the "Shareholder Loans")

in connection with a so-called back to back letter of credit dated 18 November 2023 (the "LoC") between the Seller

and the Company. As of 29 April 2026, a total amount of EUR 10,507,498.01 (in words: ten million five hundred and seven thousand

four hundred and ninety-eight euros and one cent), is outstanding under the Shareholder Loans (including all accrued interest). A list

specifying the Shareholder Loans, the accrued interest and the total outstanding amount as of 29 April 2026 is attached hereto as Exhibit

F. The respective repayment claims of the Seller under the Shareholder Loans including interest as of 29 April 2026 are collectively

referred to as the "Shareholder Loan Repayment Claim").

G. On 30 November 2020, the Seller and the Company entered into a service agreement, pursuant to which the

Company provided certain services to the Seller ("Pre-Restructuring Service Agreement"). After the Seller and the Company

applied for self-administration proceedings in May 2023, a restructuring was carried out following Seller’s withdrawal of its application

for preliminary self-administration proceedings and Company’s exit from its self-administration proceedings (the "Restructuring").

On 27 February 2024, the Company terminated the Pre-Restructuring Service Agreement with effect from the end of 29 February 2024. On 12

March 2024, the Seller and the Company entered into a corporate service agreement (the "Corporate Services Agreement").

Under the Corporate Services Agreement, the Company provides certain services to the Seller, including services related to accounting

and tax, controlling and treasury, preparation of financial statements, compliance and corporate governance, financial services and periodic

reporting in relation to a listing of the Seller’s shares on a stock exchange or over-the-counter market.

H. On 21 April 2021/29 April 2021, the Seller entered into a lease agreement (the "Lease Agreement")

with Georg and Elisabeth Däuber, Knospenstrasse 36, 80955 Munich (collectively the "Landlords") relating to the

commercial premises located in Waldmeisterstraße 93, 80925 Munich, Germany (the "Premises"). On 1 May 2021, the

Seller and the Company entered into a sublease agreement relating to the Premises (the "Sublease Agreement").

I. The Purchasers intend to acquire the Shares and the Shareholder Loan Repayment Claim from the Seller and

the Seller intends to sell and transfer the Shares and the Shareholder Loan Repayment Claim to the Purchasers ("Transaction").

J. As part of the Transaction, the Corporate Services Agreement shall be terminated with effect as of 30

April 2026. The Company shall continue to provide certain limited financial and reporting information of the Company to the Seller, to

the extent reasonably required for the Seller to fulfill certain tax and regulatory requirements following the Transaction.

K. Furthermore, as part of the Transaction, the Parties intend to agree on the procedure to achieve that

the Company takes over the Lease Agreement for the Premises in course of which the Seller is intended to be released from any liabilities

and obligations under the Lease Agreement.

2

Now, therefore, the Parties agree as follows:

1. Sale and Transfer of the Sold Shares

1.1 Sale and Transfer of the Sold Shares

(a) The Seller hereby sells and transfers with effect in rem (abtreten mit dinglicher Wirkung) the

shares with the consecutive numbers 1 to 16,794 corresponding to a share percentage of 50% of the shares in the Company and the nominal

capital of the Company to Purchaser 1 and Purchaser 1 accepts this sale and transfer; and

(b) the Seller hereby sells and transfers with effect in rem (abtreten mit dinglicher Wirkung) the

shares with the consecutive numbers 16,795 to 33,588 corresponding to a share percentage of 50% of the shares in the Company and nominal

capital of the Company to the Purchaser 2 and Purchaser 2 accepts this sale and transfer (all shares sold and transferred by the Seller

in this Clause 1.1 the "Sold Shares").

It is the joint understanding of the Parties

that the Seller shall sell and transfer all shares held by it in the Company and the Seller shall not retain any shares or other interest

in the Company.

The transfers in rem (Abtretung mit dinglicher

Wirkung) of the Sold shares in Sections 1.1(a) and 1.1(b) shall not be subject to a condition precedent (aufschiebende Bedingung)

and take immediate effect in rem (mit sofortiger dinglicher Wirkung).

1.2 Ancillary Rights

The Sold Shares are sold and transferred together

with any and all rights and obligations pertaining thereto (Nebenrechte) including the right to any undistributed profits for the

current business year and for any prior business years of the Company.

1.3 Consent of the Seller, No Right of First Refusal

Pursuant to section 14 para. 1 of the

articles of association of the Company, the transfer of the Sold Shares requires the approval of the Company’s shareholders with

a majority of at least 80% of the share capital. In addition, pursuant to section 14 para. 2 of the articles of association of the

Company the shareholders of the Company have a Right of First Refusal. As a matter of precaution: The Seller is the sole shareholder of

the Company. The Seller hereby gives its consent to the Transaction. Section 14 para 2 of the articles of association is not applicable.

2. Sale and Assignment of Shareholder Loan Repayment Claim; Standstill

2.1 Sale and Assignment

The Seller hereby sells and assigns with immediate

effect in rem (sofortiger Wirkung) 50 % of the Shareholder Loan Repayment Claim to the Purchaser 1 and 50 % of

the Shareholder Loan Repayment Claim to the Purchaser 2, whereby an indivisible cent amount shall be allocated to Purchaser 1,

which hereby each accept such sale and assignment. The Company hereby consents to such assignments. The Company and the respective Purchaser

may after the notarization of this agreement enter into a separate loan agreement governing the respective part of the Shareholder Loan

Repayment Claim acquired by the respective Purchaser under this Section 2.1. Such loan agreement shall not require the consent of

any of the other Parties, provided that Section 2.2 remains unaffected and provided further that a qualified subordination as set

out in Section 2.3 shall be included in the respective loan agreement.

3

2.2 Standstill

(a) The Purchasers hereby undertake vis-à-vis the Seller (but not vis-à-vis the

Company, neither directly nor by way of a contract for the benefit of a third party (kein Vertrag zu Gunsten Dritter)) that they

will not demand, enforce or otherwise seek repayment, whether fully or partly, of the Shareholder Loan Repayment Claim for a period of

two years following the Signing Date.

(b) Nothing in this Clause shall be construed as a waiver or deferral (Stundung) of the Shareholder

Loan Repayment Claim.

2.3 Qualified subordination (Qualifizierter Rangrücktritt)

(a) As of the Signing Date, each Purchaser, each as holder of the acquired part of the Shareholder Loan Repayment

Claim, hereby subordinates, pursuant to Section 19 para. 2 sentence 2 and Section 39 para. 2 of the German Insolvency Code (“InsO”),

the part of the Shareholder Loan Repayment Claim acquired by such Purchaser (including any ancillary rights (Nebenrechte) and any

present and future claims for principal, interest (including default interest) and costs arising out of or in connection with the Shareholder

Loans and/or the Shareholder Loan Repayment Claim) (collectively, the “Subordinated Receivables“) to the claims of

all other present and future creditors of the Company (other than (i) creditors whose claims are already subordinated by agreement and

rank equally with the Subordinated Receivables, and (ii) equally ranking creditors) to such extent that the Subordinated Receivables may

only be asserted and satisfied after satisfaction in full of all other claims against the Company (including the claims referred to in

Section 39 para. 1 nos. 1–5 InsO), but prior to shareholders’ claims for repayment of capital contributions within the meaning

of Section 199 sentence 2 InsO, and only out of (i) future net profits (künftige Jahresüberschüsse), (ii) a liquidation

surplus (Liquidationsüberschuss) or (iii) other free assets (sonstiges freies Vermögen) of the Company which remain

after satisfaction of such other creditors and which are not required for capital maintenance purposes (the “Subordination”).

(b) The Parties agree that the Subordination shall also apply outside insolvency proceedings, i.e. prior to

the opening of insolvency proceedings over the assets of the Company. Accordingly, no payment (and no enforcement) in respect of the Subordinated

Receivables shall be made if and to the extent that the Company is at the relevant time unable to pay its debts as they fall due (zahlungsunfähig)

or over-indebted (überschuldet) within the meaning of Sections 17 and 19 InsO, or would become unable to pay its debts as

they fall due or over-indebted as a result of such payment or enforcement. For the purposes of avoiding illiquidity within the meaning

of Section 17 InsO, the Subordinated Receivables shall be deemed not to be seriously demanded (nicht ernsthaft eingefordert). For

the avoidance of doubt, the Purchasers shall refrain from any acts in relation to the Subordinated Receivables that would constitute,

trigger or deepen any ground for insolvency of the Company under German insolvency law.

(c) The Parties agree that the Subordination constitutes neither a deferral/moratorium (Stundung) nor

a waiver (Verzicht) of any Subordinated Receivables.

PRESS RELEASE

Sono Group N.V. Completes Exit from Legacy Solar Operations

Transfer of Sono Motors to Its Management

Team Marks Full Completion of the Strategic Transition Announced in March 2026; Sono Group Currently Operates as a Focused Digital Asset

Treasury Company

Munich, May 8, 2026 – Sono

Group N.V. (Nasdaq: SSM) (hereafter

referred to as “Sono” or the “Company”) today announced the completion of a decisive milestone in its ongoing

strategic transformation: the formal transfer of its now former subsidiary Sono Motors GmbH ("Sono Motors") to companies controlled

by Sono Motors' own management team. The transaction closed and took legal effect on May 4, 2026, bringing to a close the solar exit

the Company announced in March. Sono Group holds no further equity interest in Sono Motors and carries no ongoing operational obligations

to the business.

With this transaction complete, the Company turns fully to the Treasury Strategy:

acquiring Bitcoin and generating yield through a covered-call approach under its institutional ISDA framework. The proceeds of the Company's

March 2026 financing were deployed into Bitcoin acquisition immediately upon receipt, capital that would otherwise have been partially

absorbed by legacy solar operations. With the exit complete, there is no longer a competing claim on that capital.

The legacy solar business was transferred to Sono Motors' two managing directors,

Denis Azhar and Jan Schiermeister, who acquired it directly, together with the technology and the team they led. The brand's solar heritage

and the people behind it remain in capable hands. Sono Group retains an irrevocable, royalty-free license to continue operating under

the Sono name for its stock exchange listing and securities trading.

Sono Group currently operates as a digital asset treasury company and will

continue to evaluate opportunities to build long-term shareholder value as its strategy develops.

"I want to thank the Sono Motors team: what Denis, Jan and their colleagues

built earned real industry recognition, and I'm glad it passes to people who believe in it. For Sono Group, the transformation we announced

in March is now complete. We are focused on execution and on delivering results for our shareholders," said Kevin McGurn, Managing

Director and CEO of Sono Group N.V.

Full details of the transaction, including the Share Purchase and Transfer

Agreement, are set forth in the Company's Amendment No. 1 on Form 8-K/A filed with the U.S. Securities and Exchange Commission on May

6, 2026, available at www.sec.gov and on the Company's investor relations website at ir.sonomotors.com.

END

“might,” “plan,” “possible,” “potential,” “predict,” “project,”

“seek,” “should,” “will,” “would” and similar expressions may identify forward-looking

statements, but the absence of these words does not mean that a statement is not forward-looking. The forward-looking statements contained

in this press release are based on certain assumptions and analyses made by the management of the Company considering their respective

experience and perception of historical trends, current conditions, and expected future developments and their potential effects on the

Company as well as other factors they believe are appropriate in the circumstances. There can be no assurance that future developments

affecting the Company will be those anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which

are beyond the control of the parties), or other assumptions that may cause actual results or performance to be materially different

from those expressed or implied by these forward-looking statements, including the consummation and timing of any transactions as part

of the Treasury Strategy, and the cash flow to the Company therefrom; the occurrence of any uncured event of default or any event, change

or other circumstance that could give rise to the termination of the Company’s ISDA Master Agreement relating to the Treasury Strategy;

the outcome of any legal proceedings that may be instituted against the Company; risks associated with the Treasury Strategy replacing

the former plans and operations of the Company including the legacy solar operations; potential difficulties in employee retention as

a result of the Treasury Strategy; whether the Company will be able to maintain compliance with the continued listing standards of The

Nasdaq Stock Market LLC or comply with the initial listing standards of another national securities exchange; the ability of the Company

to service or otherwise pay its debt obligations; market acceptance of the Company’s product offerings; that the Company will have

sufficient capital to operate as anticipated; the demand for the Company’s products; and global supply chains and legislative,

regulatory and economic developments in general. Should one or more of these risks or uncertainties materialize or should any of the

assumptions being made prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements.

The Company undertakes no obligation to update or revise any forward-looking statements, whether because of new information, future events,

or otherwise, except as may be required under applicable securities laws.
