In connection with Mr. Kilde's departure, T1 Energy Norway AS (formerly known as FREYR Battery Norway AS) (a wholly-owned subsidiary of the Company) and Mr. Kilde entered into a Separation Agreement on April 22, 2026 (the "Separation Agreement"), pursuant to which Mr. Kilde will be entitled to receive a severance payment of NOK 5.5 million to be paid in twelve equal installments following the Effective Date. Options and restricted stock units that Mr. Kilde has received to date under the Company's 2021 Equity Incentive Plan (as may be amended and/or amended and restated from time to time) (the "Plan") shall remain outstanding and eligible to vest in accordance with the terms and conditions of the Plan and the applicable award agreements under which they were granted; the terms of Mr. Kilde's options have also been extended such that they may be exercised beyond the default period of three months post-employment under the Plan. Additionally, Mr. Kilde is expected to receive a bonus with respect to the Company's bonus scheme for 2025, in an amount, which is expected to be payable in cash, to be determined and finalized by the Company in its discretion and communicated to him as soon as practicable following the execution of the Separation Agreement.

The foregoing description of the Separation Agreement does not purport to be complete and is qualified in its entirety by reference to the Separation Agreement, which is attached to this Current Report as Exhibit 10.1 and incorporated herein by reference.

As previously disclosed in the Company's Current Report on Form 8-K filed with the Securities and Exchange Commission on February 6, 2026 (the "CAO Appointment 8-K"), Tom Mahrer was appointed as the Company's Chief Accounting Officer and Corporate Controller. The Company stated in the CAO Appointment 8-K that it was still finalizing the terms of Mr. Mahrer's employment and that such arrangements would be separately announced when finalized. On April 27, 2026, the Company and Mr. Mahrer entered into an offer letter (the "Mahrer Offer Letter") setting forth the terms of Mr. Mahrer's employment.

Under the terms of Mahrer Offer Letter, Mr. Mahrer will be eligible to receive an annual base salary, participate in the group bonus scheme with an annual cash bonus and receive equity awards in accordance with the Company's 2021 Equity Incentive Plan (amended and restated as of April 22, 2024).

## Exhibit 10.1

**Exhibit 10.1**

This **Separation Agreement** (the "**Separation Agreement**") is made 22 April 2026

Between

**Einar Kilde**

(hereinafter referred to as the "**Employee**")

and

**T1 Energy Norway AS** (formerly known as FREYR Battery Norway AS)

(organization number 929 340 019)

(hereinafter referred to as the "**Employer**" or the "**Company**", together with its subsidiaries, affiliates, successors or assigns, the "**Group**"):

1. Termination of Employment

1.1 The parties agree that the Employee's employment with the Company shall terminate on 22 April 2026
(the "**Termination Date** ").

1.2 In the event of any conflict between earlier written or oral agreements and this Separation Agreement,
this Separation Agreement shall prevail.

2. Severance pay and holiday pay

2.1 The Employee is entitled to severance pay (the "**Severance Pay** "), equivalent to NOK 5,500,000.

2.2 The Severance Pay shall be paid on the Company's ordinary paydays in twelve (12) equal instalments following
the Termination Date.

2.3 The Severance Pay does not give rise to holiday pay or pension contributions.

2.4 The Employee shall receive accrued, but previously unpaid, holiday allowance until the Termination Date.
The holiday allowance shall be paid on the Company's first ordinary payday following the Termination Date.

2.5 Any accrued holiday shall be considered taken out by the Employee prior to the Termination Date and the
Employee is not entitled to any additional compensation in this regard.

3. Taxes, offset of any claims etc.

3.1 Each party shall be responsible for taxes, duties etc. for which such party is liable to pay as a result
of this Separation Agreement. Tax deductions are made from payments under this Separation Agreement and the amount will be reported to
the tax authorities pursuant to applicable law.

3.2 The Company is entitled to offset any claim the Company may have against the Employee at the Termination
Date (for instance travel advances or advanced salary payments) in the benefits under this Separation Agreement.

4. Employee Benefits

4.1 The Employee will keep the Employee's benefits until the Termination Date.

4.2 Membership in insurance and pension schemes will continue until the Termination Date.

4.3 The Employee may be entitled to continue with the insurance schemes privately and is therefore encouraged
to contact the insurance provider (Storebrand) directly to receive a private offer.

5. RSUs and options

5.1 The Employee has been granted 210,000 restricted stock units (the "**RSUs**") in accordance
with the Group's 2021 Equity Incentive Plan (as may be amended and/or restated from time to time, the "**Plan** ")
and the Action by Written Consent of the Compensation Committee of the T1 Energy Inc Board of Directors, dated 23 June 2025, which RSUs
vest annually in three equal tranches beginning on 23 June 2026. The RSUs shall remain outstanding and eligible to vest following the
execution of this Separation Agreement in accordance with the Plan and the terms under which they were granted.

5.2 The Employee has also been granted options (the "**Options**") in accordance with the Plan.

5.3 Notwithstanding this Separation Agreement and the termination of employment with the Company, the Employee
shall remain subject to the terms and conditions of the Plan. However, the exercise period for the Options subject to the Plan shall be
the same as if the Employee had stayed at the Company as an employee and therefore the three month exercise period for "leaver employees"
shall not be applicable for the Employee. All Options must be exercised in accordance with the Plan and the terms under which they were
granted (save for the exercise period modification set forth above).

5.4 The RSUs and Options set forth in this clause 5 shall not be deemed to confer employee status after the
Termination Date.

5.5 Notwithstanding any other provision of this Separation Agreement, the RSUs and Options shall continue
to vest in accordance with the terms and conditions of the Plan and the applicable award agreement under which they were granted.

5.6 In the event that vesting of the RSUs or Options in accordance with the Plan is not possible for any reason,
the parties shall negotiate in good faith to agree upon an alternative compensation arrangement of equivalent value.

6. Bonus

6.1 The Employee will be paid a bonus with respect to the Company's bonus scheme for 2025, in the amount
to be determined by the Company in its discretion and communicated to the Employee as soon as practicable following the execution of this
Separation Agreement.

7. Confidentiality about this Separation Agreement, disparagement etc.

7.1 The parties take on a duty to keep confidential the contents of this Separation Agreement. Notwithstanding
the foregoing, nothing in this Separation Agreement shall prohibit either party from disclosing the existence or contents of this Separation
Agreement to the extent such disclosure is required by applicable law or regulation, or pursuant to any order or request of a court, governmental
body or regulatory authority, or where disclosure is made to immediate family, is necessary for financial reasons in relation to authorities,
or is for the purposes of receiving any legal advice. Any violations to this duty of confidentiality may imply that all, or part of, payments
and benefits under this Separation Agreement are lost, cf. below.

7.2 The Company and the Employee shall refrain from malicious disparagement or otherwise making harmful or
unfavourable statements that can damage the reputation of the other party. Hereunder, the Company and the Employee shall not, and the
Company shall instruct its respective senior executive officers and directors not to, engage in any conduct or make any statement disparaging
in any way the other party's business or reputation, or any goods or services offered by the other party. Furthermore, the Company
and the Employee, shall not, and the Company and the Group shall instruct such above mentioned individuals not to, engage in any other
conduct or make any other statement that could reasonably be expected to impair the other party's goodwill or reputation.

7.3 All payments due to be made by the Company and any other benefits pursuant to this Separation Agreement
are conditional on and subject to the Employee complying – and having complied – with all regulations set out in this Separation
Agreement and the employment agreement and having performed the Employee's duties in a satisfactory manner. Consequently, in case
of a breach or other violation of the regulations set out in this Separation Agreement, hereunder, but not limited to, the non-disparagement
clause (Clause 7.2), the confidentiality clause (Clause 7.1), or the employment agreement, the Company is entitled to full repayment of
all payments made pursuant to this Separation Agreement.

7.4 The Employee shall be relieved from any applicable non-compete obligations pursuant to the employment
agreement.

8. Return of equipment/documents, expense claims and confidentiality

8.1 A fundamental asset for the Company is its intellectual property rights. As a consequence, it is of crucial
importance to the Company that the Employee does not disclose confidential or secret information, and it will be considered a material
breach of this Separation Agreement that can imply that the Company is not obligated to pay any Severance Pay or any other benefits under
this Separation Agreement if the Employee does disclose such information. The terms "confidential" and "secret"
information (hereinafter "**Confidential Information**" and "**Secret Information**") mean all and any information
(regardless of whether such information or data is in oral, written, machine readable or other form) which is not in the public domain
including, without limitation, information comprising of or relating to drawings, manuals, notebooks, reports, models, know-how, inventions,
formulae, processes, machines, compositions, computer programs, accounting methods, business plans and information systems. Against this
background, the Employee commits to the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Employee's obligation not to disclose Confidential and/or Secret Information shall continue after
the Termination Date. The Employee may however make use of the general competence that the Employee has accrued during work for the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) All equipment and items that belong to the Company and that the Employee has in possession (including,
but not limited to, access cards, credit cards, etc.) shall be returned to the Company by such date as determined by the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Company phone and laptop: The Employee can opt to buy the Company phone and/or Company laptop, by informing
the Company by such date as determined by the Company. In such case the cost will be deducted from salary/Severance Pay in accordance
with Norwegian taxation laws, and ownership of purchased equipment will be transferred to the Employee.

If the Employee chooses not to buy the Company phone, they can keep it until such date as determined by the Company. During this period normal terms of use, as outlined in Company policies, apply.

If the Employee chooses not to buy the Company laptop, it should be returned to the Company no later than such date as determined by the Company.

8.2 All documents and electronically stored information that belongs to the Company (including Confidential
and Secret Information) shall either be delivered to the Company or stored on Company servers no later than such date as determined by
the Company.

8.3 By such date as determined by the Company, the Employee shall remove private emails and documents from
the Company's electronic systems. From such date as determined by the Company, the Employee will no longer have access to the Company's
system or email accounts. The Company reserves the right to, in accordance with the data protection legislation, access the Employee's
email box to the extent necessary to safeguard the day-to-day management of business and to safeguard other interests.

8.4 Anne Ekern on behalf of T1 Energy, is responsible for updating the Employee profile in the Company's
HR-system, Visma and Global Shares Gateway with personal email and personal phone number (if relevant), so that a representative from
the Company can reach the Employee if needed to uphold the terms in this Separation Agreement. This information needs to be given at a
date as determined by the Company. The Company is not liable in the event that the Employee fails to provide updated personal contact
details as relevant or provides incorrect or partial contact information.

8.5 The Employee must file any not yet filed expense claims by such date as determined by the Company. Any
expenses not filed by this date are forfeited and will not be reimbursed.

9. Employment Verification Letter

9.1 The Employee will receive the Company's standard Employment Verification Letter in accordance with
law.

10. Full and final settlement

10.1 By signing this Separation Agreement, the parties agree that the Employee's employment with the
Company and/or any other group company shall be terminated on the terms set forth herein, and that the parties no longer have any further
claims toward the other or any other group company except for what is agreed upon in this Separation Agreement. This includes that the
Employee – after the signing of the Separation Agreement – will not contest the correctness/validity of the termination of
the employment in any jurisdiction.

10.2 The Employee further waives any and all preferential right(s) to employment according to the Working Environment
Act or any other applicable law/regulation.
