**Item 1.01 Entry into a Material Definitive Agreement.**

On March 6, 2026, Nuvve Holding Corp. (the "Company" or "Nuvve") entered into a cooperation agreement (the "Cooperation Agreement") between and among the Company, Oelion AB, a company organized under the laws of Sweden ("Oelion"), and OMNIA Group Holdings AG, a company organized under the laws of Switzerland ("Omnia"). Concurrently with entry into the Cooperation Agreement the Company, Oelion and Omnia also entered into (i) a service agreement for engineering and managerial consulting services (the "Managerial Services Agreement") and (ii) an aggregation service agreement for battery energy storage system (BESS) (the "Aggregation Service Agreement" and together with the Cooperation Agreement and the Managerial Services Agreement, the "Omnia Venture Agreements").

Pursuant to the Omnia Venture Agreements, the Company has acquired (i) an option regarding an assignment of a 50 MW battery energy storage system (BESS) project located at Marviken, Sweden (the "Envisaged Project") and to hold an interconnection agreement with the relevant grid operator regarding the interconnection of the Envisaged Project to the electricity grid (the "Interconnector Agreement"), (ii) a right of first refusal, and (iii) an exclusive right to provide energy aggregation services as well as engineering and managerial consulting services to any new project of OMNIA and its affiliates in Europe. Pursuant to the Managerial Services Agreement the Company will provide its technology and expertise in management of advanced energy storage and grid modernization solutions and will receive payments from Omnia in the first year of approximately $1,345,389 and with a continuing term of twenty years, subject to customary termination provisions. In consideration for this, the Company has agreed to issue, subject to the accomplishment of various contractual and operational milestones, 814,532 shares of Nuvve's common stock, par value $0.0001 per share, (the "Common Stock Consideration"), which is equivalent to approximately 19.9% of Nuvve's outstanding Common Stock as of the date of execution of the Cooperation Agreement representing an aggregate value of approximately $1,018,165 as of the close of trading on March 5, 2026, and, subject to prior shareholder approval and the accomplishment of various contractual and operational milestones, shares of Series B Convertible Preferred Stock of Nuvve (the "Preferred Stock Consideration"). Subject to completion of the requisite milestones, per the Cooperation Agreement, the Company will seek to hold a shareholder meeting for purposes of approval of the issuance of the Preferred Stock Consideration before any such issuance is made.

The foregoing descriptions of the terms of the Cooperation Agreement, Aggregation Service Agreement and Managerial Services Agreement are not intended to be complete and are qualified in their entirety by reference to the full text of the Cooperation Agreement, Aggregation Service Agreement and Managerial Services Agreement, which are filed as Exhibits 10.1, 10.2, 10.3, respectively, to this Current Report on Form 8-K and are incorporated by reference herein.

**Item 3.02 Unregistered Sales of Equity Securities.**

The information set forth in Item 1.01 of this Current Report on Form 8-K is incorporated by reference into this Item 3.02.

The offer and sale of the securities in the Cooperation Agreement was made pursuant to the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the "Securities Act"), and/or Regulation S thereunder.

This report does not constitute an offer to sell or the solicitation of an offer to buy the securities in the described offering, nor shall there be any offer, solicitation or sale of the securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.

**Item 7.01 Regulation FD Disclosure.**

On March 6, 2026, the Company issued a press release announcing the entry into the Omnia Venture Agreements. A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K, and is incorporated herein by reference.

2. Right of First Refusal

2.1 OMNIA shall, and hereby undertakes to procure that each of its Affiliates shall, grant Nuvve an exclusive
right of first refusal (the "**ROFR**") with respect to new battery energy storage system projects developed, or to be developed,
or owned by OMNIA or its Affiliates in Europe (the "**European Projects** "). The existing European Projects are listed in  **<u>Exhibit 2.1</u>** . "**Affiliate**" means any entity directly or indirectly controlled by, controlling, or under
common control with OMNIA. For this purpose, "control" means the possession, directly or indirectly, of the power to direct
the management and policies of an entity, whether through the ownership of voting securities, by contract, or otherwise.

2.2 The ROFR shall be triggered if OMNIA or any of its Affiliates receives a bona fide third-party offer to
acquire or invest in any European Project. Upon receipt of such offer, OMNIA shall provide Nuvve with written notice (the "**ROFR Notice**") containing the material terms and conditions of the third-party offer.

2.3 Nuvve should have 30 calendar days from receipt of the ROFR Notice to elect to acquire the European
Project on the same terms and conditions as set forth in the third-party offer by providing written notice to OMNIA.

2.4 If Nuvve timely elects to exercise the ROFR, Nuvve and OMNIA shall proceed to negotiate and execute definitive
agreements for the acquisition of the European Project on the terms set forth in the ROFR Notice. Notwithstanding the terms set forth
in the ROFR Notice, Nuvve and OMNIA shall agree on terms not less favorable to Nuvve than the terms set out in Sections 6.2.9
to 6.2.11 below, as applicable, unless Nuvve agrees to terms less favorable.

2.5 If Nuvve does not timely exercise the ROFR, OMNIA and its Affiliates shall be free to proceed with the
transaction with the third party on the same terms and conditions as set forth in the ROFR Notice for a period of 30 calendar days. If
the transaction with the third party is not consummated within such period, the ROFR shall again apply to the European Project.

2.6 The ROFR shall commence on the Signing Date and shall continue for a period of 15 years, unless earlier
terminated in accordance with its terms.

2.7 Following the Signing Date, the Parties shall in good faith discuss and agree on a binding ROFR Term Sheet,
which shall set out the minimum commercial and legal terms applicable to any transaction carried out pursuant to Nuvve's exercise
of the ROFR. The ROFR Term Sheet, once agreed, shall apply to all ROFR transactions regardless of deviating terms in any third-party
offer, unless such terms are expressly more favourable to Nuvve.

2.8 The ROFR shall be binding on OMNIA, the Swedish SPV, OMNIA's other Affiliates and each of their successors.

3. Exclusivity for Services

3.1 OMNIA hereby grants Nuvve an exclusive right to provide (i) energy aggregation services and (ii) engineering
and managerial consulting services for all European Projects.

3.2 For the avoidance of doubt, this exclusivity is intended to ensure that, with respect to any European
Project, Nuvve shall be the sole provider (directly or indirectly through its Affiliates or designees) of energy aggregation services
as well as engineering and managerial services to the relevant project, owner or operator, as applicable.

3.3 OMNIA shall, and hereby undertakes to procure that each of its Affiliates shall, grant and observe an
exclusivity in favor of Nuvve on terms no less favorable to Nuvve than those set forth in  **<u>Exhibit 3.3(a)</u>** (energy aggregation
services) and  **<u>Exhibit 3.3(b)</u>** (engineering and managerial consulting services). Unless otherwise agreed between OMNIA
and Nuvve, or their Affiliates responsible for the specific European Project, the monthly instalments to be paid in advance to Nuvve for
the provision of engineering and managerial consulting services are set out in **Exhibit 3.3(c)**.

3.4 OMNIA shall not, and shall procure that its Affiliates shall not, appoint or engage any third party to
provide energy aggregation services or engineering and managerial consulting services for any European Project.

3.5 The exclusivity pursuant to this Section 3 shall not apply with respect to a specific European Project
only if and to the extent that Nuvve has provided a written declination to provide energy aggregation services or engineering and managerial
consulting services for such European Project.

3.6 The exclusivity under this Section 3 shall commence on the Signing Date and continue for a period
of fifteen (15) years. For the avoidance of doubt, this term is aligned with the term specified in Section 2.6 for the ROFR
in respect of European Projects.

3.7 The Parties acknowledge that the intention of this Section 3 is complementary to, and does not limit,
the obligation of the Parties to enter into the Consulting Service Agreements as defined in Section 4 below, and that this Section 3
is to be interpreted in a manner that preserves such obligation and Nuvve's exclusivity set forth therein.

3.8 OMNIA shall, and shall procure that its Affiliates shall, do all acts and things, and execute all further
instruments and documents, as are reasonably necessary to give full effect to Nuvve's exclusivity under this Section 3.

3.9 A declination by Nuvve pursuant to this Section 3 shall not affect (i) any existing agreements, (ii) the
validity of the exclusivity rights under this Section 3, or (iii) Nuvve's ability to enter into future agreements under this Section
3. 4. Service Agreement Obligation

On the Signing Date, the Parties shall enter into a service agreement pursuant to which Nuvve shall provide engineering and managerial consulting services to the Swedish SPV in connection with the Envisaged Project substantially in the form as attached hereto as **<u>Exhibit 4</u>** (the "**Consulting Service Agreements**"). Nuvve's obligation to enter into the service agreement in accordance with section 4 is conditioned upon Nuvve's prior written approval of Exhibit 4 and the key terms.

5. Option Right to Enter into Aggregation Service Agreement

5.1 OMNIA and the Swedish SPV hereby grant Nuvve an exclusive option right ()"**Aggregation Option Right** ")
to enter into an aggregation service agreement in relation to the Envisaged Project ()"**Aggregation Service Agreement** ").

5.2 The Aggregation Option Right may be exercised by Nuvve at any time during the Aggregation Option Period
(as defined below) by providing written notice to OMNIA of its intention to exercise the Aggregation Option Right ()"**Aggregation Exercise Notice** ").

5.3 The "**Aggregation Option Period**" shall commence on the Signing Date and shall continue
for a period of fifteen (15) years.

5.4 Aggregation Option Right Terms

Upon receiving an Aggregation Exercise Notice, the Parties shall execute, in good faith, a definitive agreement for the Aggregation Service Agreement. The terms and conditions of the Agreement shall be substantially in the form attached hereto as **<u>Exhibit 5.4</u>**. In any case, the terms of the Aggregation Service Agreement shall not be less favorable to Nuvve than the terms set forth in **<u>Exhibit 5.4</u>**, unless Nuvve consents to less favorable terms.

5.5 OMNIA and the Swedish SPV shall, without undue delay, notify Nuvve in writing about any material occurrences
that may affect Nuvve's decision to exercise the Aggregation Option Right. OMNIA and the Swedish SPV shall also provide Nuvve with the
necessary information and documentation to enable Nuvve to determine whether to exercise the Aggregation Option Right.

6. Option Right to Acquire Marviken Assets

6.1 General Provisions

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.1.1 In exchange for Nuvve's issuance of the Option Consideration to OMNIA and/or its designees, OMNIA

execution of this CA in accordance with Exhibit 6.2.6(a), as defined below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.1.2 Notwithstanding anything to the contrary in this CA or in Exhibit 6.2.6(a), no issuance, vesting, conversion,
transfer, release or deposit into escrow of any Preferred Stock, Common Stock or any other equity instrument (including the Option Consideration)
shall occur prior to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i) The Transfer of Lease Agreement

ii) The transfer of the grid connection

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.1.3 OMNIA and the Swedish SPV shall, without undue delay, notify Nuvve in writing about any material changes
to the Interconnector Agreement and the Lease Agreement. This includes, but is not limited to, the Swedish SPV entering into the Interconnector
Agreement. OMNIA and the Swedish SPV shall also provide Nuvve with the necessary information and documentation to enable Nuvve to determine
whether to exercise the Option Right.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.1.4 The Option Right may be exercised by Nuvve at any time during the Option Period (as defined below) by
providing written notice to OMNIA of its intention to exercise the Option Right ()"**Exercise Notice** ").

Notwithstanding the foregoing, (x) the Indemnified Party may take over the control of the defense or settlement of a third-party claim
at any time if it irrevocably waives its right to indemnity under this Section 6.2.11 with respect to such claim and (y) the Indemnifying

specified in  **<u>Exhibit 2.1</u>** for the Project in Marviken, Sweden ()"**Services** "). The Services comprise the following
revenue streams related to ancillary services and energy arbitrage:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12.1.1 Frequency Containment Reserve – Normal ()"**FCR-N** "): This service constitutes
a primary control reserve, which is automatically activated to stabilize the grid frequency around 50 Hz in the event of supply-demand
imbalances.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12.1.2 Frequency Containment Reserve – Disturbance ()"**FCR-D** "): This
service constitutes a primary control reserve automatically activated during significant frequency disturbances to restore grid stability,
requiring rapid power adjustment capabilities and available in both upward (increasing output) and downward (decreasing output) directions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12.1.3 Automatic Frequency Restoration Reserve ()"**aFRR** "): This service constitutes a secondary
control reserve service that automatically restores the frequency to its nominal value and manages power exchanges between control areas
through continuous activation signals.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12.1.4 Manual Frequency Restoration Reserve ()"**mFRR** "): This service constitutes a tertiary control
reserve service that is manually activated to replace activated secondary reserves and restore the balance between generation and consumption
over longer timeframes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12.1.5 Day-Ahead/Intraday Arbitrage: This service involves a trading strategy of purchasing electricity at low
prices and selling at high prices, utilising price volatility across different timeframes to maximise revenue.

For purposes of this Agreement, "**Ancillary Services**" refers to the frequency control reserve services specified in Sections 2.1.1 – 12.1.4 (FCR-N, FCR-D, aFRR, and mFRR), while "**Energy Arbitrage**" refers to the Day-Ahead/Intraday Arbitrage trading strategy specified in Section 12.1.5.

26.1 The Parties and the Guarantor acknowledge that in connection with this Agreement and the providing of

as information regarding the business, financial situation, products and prospects, processes and methodologies, and any other documentation
in whatever form ()"**Information** "). Such Information is confidential information in case it is marked as confidential or
described as confidential at the time of disclosure or if a reasonable third party would define it of such quality which needs protection
and therefore should be treated confidential ()"**Confidential Information** ").

Confidential Information does not include any Information,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;26.1.1 which becomes generally available to the public other than because of a breach of this Section 26 or another
obligation under this Agreement,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;26.1.2 which is received from a third party, except if provided on behalf of the Service Provider and provided
that the third party is not bound by an obligation of confidentiality with respect to such information towards the respective disclosing
party,

13 of 20

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;26.1.3 which was legally in a Party's or the Guarantor's possession without obligations of confidentiality to
the other Party or the Guarantor prior to such information being furnished as Confidential Information, or

on any Confidential Information of the other Party or the Guarantor.

26.2 In respect of Confidential Information of the Parties and the Guarantor, each Party and the Guarantor
receiving such Confidential Information ()"**Information Recipient**") shall

26.3 If the Developer, the Guarantor, or any of their respective Affiliates discloses any Confidential Information
of the Service Provider in breach of this Agreement, the Developer shall pay liquidated damages to the Service Provider in an amount equal
to EUR 50,000 per breach.

26.4 For the avoidance of doubt, a breach that continues over time shall constitute a continuing breach, and
liquidated damages shall accrue for each calendar month (or part thereof) during which the breach persists. Repeated disclosures or separate
acts of unauthorized disclosure shall be treated as separate breaches, each giving rise to liquidated damage.

26.5 Payment of liquidated damages does not limit the Service Provider's right to claim higher proven

## Exhibit 99.1

**Exhibit 99.1**

**Nuvve Partners with OMNIA Global to Address 1GW Development Pipeline with First 50MW/75MWh Battery Energy Storage System in Sweden**

*Partnership Opens New Revenue Market*

SAN DIEGO & ZÜRICH--(BUSINESS WIRE)--Nuvve Holding Corp. (Nasdaq: NVVE), a global leader in advanced energy storage and grid modernization solutions, today announced it is partnering with OMNIA Global to jointly address a pipeline in excess of 1 GW over the next 24 months with the supporting financing. The first and earliest project is a 50MW/75MWh European CE-approved battery energy storage system (BESS) located in Sweden. This marks a significant expansion of the company's European energy storage footprint.

BESS plays a critical role in modern electricity grids by balancing supply and demand, integrating renewable energy, and enhancing grid stability. BESS technology enables the storage of excess energy generated during periods of low demand and its rapid deployment during peak usage, improving reliability while reducing dependence on fossil fuel-based generation.

Sweden represents one of Europe's most attractive markets for energy storage investment, driven by its ambitious climate goals, high penetration of renewable energy, and well-developed electricity market. The country's growing wind and solar capacity, combined with increasing electrification across transportation and industry, has created strong demand for flexible storage solutions. Supportive regulatory frameworks and market structures further enhance the commercial viability of BESS assets, positioning Sweden as a strategic hub for long-term energy storage development.

The first project is expected to commence operations during the second quarter of 2026. It forms part of Nuvve's broader European development pipeline, which includes battery storage sites in several of the continent's best-performing energy markets.

Recent market conditions in these regions support potential revenues of €240,000–€300,000 per MW per year (approximately $260,000–$325,000 per MW-year). This project is expected to bring incremental revenues to Nuvve during the second quarter of 2026 after the first batteries become operational.

"The partnership represents a significant revenue opportunity spread across a pipeline exceeding 1GW, positioning Nuvve as a leading global provider of grid-scale energy storage," said Gregory Poilasne, CEO of Nuvve. "Nuvve continues to build a high-quality portfolio designed to deliver long-term, recurring value through asset ownership, asset management, and exclusive development rights."

Nuvve will serve as the owner and asset manager for the facility and provide full market access services to optimize revenue generation and grid participation. The acquisition strengthens Nuvve's position in the rapidly growing Nordic energy storage market and reinforces its long-term strategy of deploying scalable, revenue-generating infrastructure.

This transaction aligns with Nuvve's broader strategy to expand its global energy storage and grid services platform by leveraging long-term contracts, advanced software, and market optimization capabilities to deliver sustainable growth.

Nuvve also secured exclusive rights to support and deploy battery energy storage projects developed through exiting partnerships that OMNIA Global established. Nuvve also has a Right of First Refusal to acquire ownership stakes in future deployments within this pipeline.

"We see Nuvve as a uniquely fitting partner to efficiently project manage and execute the roll-out of our pipeline utilizing Nuvve's unique load balancing software and years of experience in BESS from the early days of the market. The European market has high arbitrage opportunities for fast movers and with the partnership of Nuvve we have found a partner that efficiently and comfortably can look at a large scale roll out with the most experienced team of its sector," said Daniel Hansen, CEO and Chairman of OMNIA Global.
