1.01. Entry into a Material Definitive Agreement.

On July 28, 2026 (the “Effective Date”),

T1 Energy Inc. (the “Company”) purchased from Evervolt Green Energy Holding Pte, Ltd., a private company limited by

shares organized under the laws of Singapore (the “Seller”), all of the Seller’s right, title and interest in

and to certain intellectual property and proprietary rights (the “Acquired IP”), and related rights, and certain other

assets (together, the “Purchased Assets”) pursuant to an intellectual property purchase agreement (the “IP

Purchase Agreement”), dated the Effective Date, between the Company and the Seller, and with respect to the termination of the

Existing Licenses (as defined below and in the IP Purchase Agreement), T1 G1 Dallas Solar Module LLC (“G1”). The Acquired

IP comprises the intellectual property previously licensed to the Company and one of its subsidiaries by the Seller under the Existing

Licenses. The Existing Licenses were terminated with immediate effect upon the closing of the transaction. The Company entered into the

IP Purchase Agreement following its exercise of a call option granted to it by the Seller under a call option letter agreement, dated

July 27, 2026, between the Company and the Seller (the “Call Option Agreement”) and attached to the IP Purchase Agreement

as Schedule H.

The aggregate purchase price for the Purchased

Assets is US$133,000,000 (the “Purchase Price”), which is in addition to a US$2,000,000 option premium previously paid

by the Company in consideration for the grant of the call option. The Purchase Price is payable by the Company in four tranches: (i) US$60,000,000,

payable on the date that is three business days after the Closing Date (which is the Effective Date, as defined in the IP Purchase Agreement);

(ii) US$25,000,000, payable on September 30, 2026; (iii) US$30,000,000, payable on October 15, 2026; and (iv) US$18,000,000, payable on

October 30, 2026. Each tranche of the Purchase Price is payable, at the Company’s election, (a) in cash, (b) by the issuance to

the Seller of a number of shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”),

pursuant to the terms of the Call Option Agreement, or (c) any combination of the foregoing in such ratio as mutually agreed by the Company

and the Seller. The Company currently intends to pay the first tranche by the issuance of Common Stock.

The IP Purchase Agreement contains customary representations,

warranties and covenants of the parties, including representations of the Seller regarding its ownership of and title to the Purchased

Assets; the validity and enforceability of the Acquired IP and the absence of challenges thereto; the absence of claims, liens, charges

or encumbrances and related legal proceedings; the absence of third-party infringement, misappropriation and violation of the Acquired

IP; the Seller’s status as a non-specified foreign entity as defined pursuant to Section 7701(a)(51)(B) and Section 7701(a)(51)(C)

of the Internal Revenue Code of 1986, as amended; and general compliance. The IP Purchase Agreement provides for mutual indemnification

for third-party claims arising from Retained Liabilities (as defined in the IP Purchase Agreement) (in the case of the Seller), negligence

or willful misconduct, or material breach, as well as a Seller-specific indemnity for third-party claims alleging that the Acquired IP

infringes, misappropriates or otherwise violates any third party’s intellectual property rights. The Seller has agreed to effect all necessary

changes of ownership and recordals with respect to the Acquired IP to evidence the sale and to take all steps and provide cooperation

and assistance to the Company as may be reasonably necessary to perfect the assignment of the Purchased Assets, within 30 days of the

Closing Date.

Any shares of Common Stock issued to the Seller in satisfaction of the Purchase Price (the “Consideration Shares”) will be

issued as “restricted securities” under applicable securities laws and will initially bear a customary restrictive legend.

The number of Consideration Shares issued in satisfaction of any portion of the Purchase Price will be determined based on a 15% discount

to the volume-weighted average price of the Common Stock during a 5-trading day observation period ending two business days prior to the

date of issuance of any such Consideration Shares. However, the aggregate number of Consideration Shares issued pursuant to the Call Option

Agreement may not exceed 19.9% of the total number of shares of Common Stock of the Company issued and outstanding as of the date of the

Call Option Agreement, and if the Consideration Shares would exceed 19.9% of the total number of shares of Common Stock of the Company,

the remainder of the Purchase Price shall be paid in cash. The issuance of any Consideration Shares on any given payment date is contingent

upon the Company’s receipt of the official notice from the New York Stock Exchange of its approval of such issuance. The Company

has also agreed to file with the Securities and Exchange Commission (“SEC”), on or before the fifth business day following

each payment date on which Consideration Shares are issued, a registration statement, or a prospectus supplement to a prospectus forming

a part of an existing registration statement, covering the resale of such Consideration Shares by the Seller.

SURVIVAL; Indemnification; limitations on liability

Section 5.1

Survival. All representations, warranties, covenants, and agreements contained

in this Agreement and all related rights to indemnification and damages shall continue in full force and effect following the date hereof.

Section 5.2

Mutual Indemnification. Each Party (the “Indemnifying Party”) shall

indemnify, defend and hold harmless the other Party and such other Party’s Affiliates (as applicable) and its and their respective

directors, officers, agents, successors and assigns (each, an “Indemnified Party” and collectively, the “Indemnified

Parties”) from and against any and all loss, liability, or expense (including attorneys’ fees and costs) incurred

or suffered by any of the Indemnified Parties as a result of, or arising out of, any claim or demand by a Third Party alleging or arising

from (a) solely with respect to Seller as the Indemnifying Party, any Retained Liabilities, (b) negligence, gross negligence,

willful misconduct or fraud by the Indemnifying Party, any of its Affiliates, or its or its Affiliates’ officers, directors, members,

managers or employees, or its or their agents or subcontractors in the performance of this Agreement or (c) material breach by the

Indemnifying Party of this Agreement, in each case (in respect of the foregoing clauses (a)-(c)), except to the extent that such

loss, liability or expense (including attorneys’ fees and costs) is subject to indemnification by the other Party pursuant to this

Article V.

Section 5.3

IP Infringement Claims.

(a)

Seller shall indemnify, defend and hold harmless Purchaser and its Affiliates (“Purchaser Indemnified Party”)

from and against any loss, liability or expense (including attorneys’ fees and costs) incurred by any such party as a result of,

or arising out of, a claim or demand by a Third Party alleging that any Acquired IP, or the use thereof, infringes, misappropriates or

otherwise violates any Intellectual Property rights of any Third Party; provided that Seller shall have no such obligation to the

extent the claim or demand arises from: (i) the combination of Acquired IP with content, materials, products or services provided

by Purchaser and its Affiliates or Third Parties that is not at the direction of Seller or in compliance with Seller’s instructions

and Seller does not and should not reasonably expect such combination to occur, where the use of Acquired IP alone in the absence of such

combination would be non-infringing; or (ii) Purchaser’s failure to use updated versions of Acquired IP (which are substantially

the same or better than the previous versions of such Acquired IP) if so instructed and provided by Seller in order to avoid such infringement,

misappropriation or violation. For the avoidance of doubt, “Purchaser Indemnified Party” is an “Indemnified

Party” under Section 5.4.

(b)  Without

limiting the foregoing, if (i) a Third Party brings a claim that any Acquired IP, or the use thereof, infringes,

misappropriates or otherwise violates any Third Party’s Intellectual Property rights (an “IP Claim”),

(ii) Seller or Purchaser believes an IP Claim is reasonably likely or (iii) Purchaser’s or its licensees’ use

of the Acquired IP, or any activity with respect thereto, is enjoined as a result of, or arising out of, an IP Claim, Seller shall,

at its expense and in consultation with Purchaser, which shall act reasonably: (1) obtain a license or grant of rights under

the rights that have been infringed or otherwise violated or are alleged to be infringed or otherwise violated, or other

functionally equivalent Intellectual Property agreed upon by Purchaser (or at Purchaser’s direction acting reasonably and to

the extent commercially reasonable, require the Third Party to transfer ownership to Purchaser of such Intellectual Property

rights), which rights shall be no less favorable than the rights Seller granted to Purchaser pursuant to the IP License Agreement or

(2) modify the Acquired IP so it is non-infringing or otherwise non-violative, and deliver to Purchaser such modified Acquired

IP; provided that such modified Acquired IP is functionally equivalent to the unmodified Acquired IP. Seller shall have no

liability and no obligation under this Section 5.3 for any violation, infringement or misappropriation that arises out

of or results from the matters described in Section 5.3(a)(i)–(ii).

10

Section 5.4

Procedures. The Indemnified Party shall be entitled to indemnification hereunder only: (a) if it gives written notice

to the Indemnifying Party of any losses or claims, suits or proceedings by Third Parties which may give rise to a claim for indemnification

with reasonable promptness after receiving written notice of such claim (or, in the case of a proceeding, is served in such proceeding)

or becoming aware of any such loss; provided, however, that failure to give such notice shall not relieve the Indemnifying

Party of its obligation to provide indemnification, except if and to the extent that the Indemnifying Party is actually and materially

prejudiced thereby, and (b) once the Indemnifying Party confirms in writing to the Indemnified Party that it is prepared to assume

its indemnification obligations hereunder, the Indemnifying Party has sole control over the defense of the claim, at its own cost and

expense; provided, however, that the Indemnified Party shall have the right to be represented by its own counsel at its

own cost in such matters. Notwithstanding the foregoing, (i) no Indemnifying Party shall have the right to assume control over the

assertion of any claim, or the commencement of any action, in either case with respect to Taxes of the Indemnified Party; provided

that the Indemnified Party shall not settle or resolve any such claim or action if doing so would reasonably be expected to adversely

impact the Indemnifying Party, including increasing the Indemnifying Party’s obligations pursuant to this Agreement, without the

prior written consent of the Indemnifying Party, which shall not be unreasonably withheld, conditioned or delayed; and (ii) the Indemnifying

Party shall not settle or dispose of any such matter in any manner which would require the Indemnified Party to make any admission, or

to take any action (except for ceasing use or distribution of the items subject to the claim) without the prior written consent of the

Indemnified Party, which shall not be unreasonably withheld, conditioned or delayed. Each Party shall reasonably cooperate with the other

Party and its counsel in the course of the defense of any such suit, claim, or demand, such cooperation to include using reasonable efforts

to provide or make available documents, information and witnesses and to mitigate damages.

Section 5.5

Limitation of Liability. EXCEPT FOR A PARTY’S BREACH OF ARTICLE VI,

IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER PARTY OR TO ANY THIRD PARTY FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, INDIRECT,

OR PUNITIVE DAMAGES (INCLUDING, WITHOUT LIMITATION, LOSS OF PROFITS, LOSS OF USE OR OPPORTUNITY COSTS) RESULTING FROM, ARISING OUT OF

OR IN ANY WAY RELATING TO THIS AGREEMENT.

Party to object to the disclosure, and with respect to such order also shall first have made a reasonable effort to obtain a protective

order to protect such disclosure. Moreover, the Parties shall agree on the content of any press release or public disclosure relating

to this Agreement before such disclosure is made.

Re: Call Option Letter

Dear all,

Reference is made to (i) the IP License Agreement,

dated December 23, 2024, by and between Seller and Purchaser, as assigned and amended December 29, 2025 (the “IP License

Agreement”), (ii) the Intellectual Property License Agreement, dated July 16, 2024, as amended December 23, 2024

and December 29, 2025, by and between Seller and T1 G1 Dallas Solar Module LLC (together with the IP License Agreement, the “Existing

and Purchaser and (iv) the Patent Assignment Agreement, dated December 29, 2025, by and between Trina and Purchaser, as amended

July 6, 2026.

Further reference is made to our recent discussions

relating to the contemplated (i) acquisition by Purchaser of all Intellectual Property (as defined under the Existing Licenses) licensed

to T1 under the Existing Licenses and other assets pursuant to the purchase agreement, substantially in the form attached hereto as Schedule

granted to Seller under the 5GW TOPCon Solar Cell Technology License Agreement, dated December 29, 2025 by and between Trina and Seller

(the “5GW License” and the transaction contemplated under (i) and (ii), the “Contemplated Transaction”).

This call option letter (the “Call

Option Letter”) sets forth the terms and conditions of Seller’s irrevocable commitment to (i) sell the Purchased Assets

(as defined under the IP Purchase Agreement) to Purchaser on the terms and subject to the conditions set forth in the IP Purchase Agreement

and (ii) grant Joint Venture the Sub-License (as defined below) on the terms and subject to the conditions set forth hereunder. Capitalized

18

1. COMMITMENT TO ENTER INTO THE CONTEMPLATED TRANSACTION

1.1 Seller hereby irrevocably undertakes to sell to Purchaser the Purchased Assets on the Closing Date (as

defined under the IP Purchase Agreement) in accordance with the IP Purchase Agreement and to grant the Sub-License to Joint Venture, in

each case, at the price and on the other terms and conditions set forth in this Call Option Letter (the “Call Option”),

and to enter into the Contemplated Transaction, subject only to delivery by Purchaser, on or prior to the Expiry Date (as defined below),

of a Call Option Exercise Notice in accordance with Section 3 below.

1.2 By signing this Call Option Letter, Purchaser accepts the benefit of the Call Option as an option solely,

without any undertaking to exercise the Call Option. Seller further acknowledges that nothing herein shall constitute in any manner whatsoever

an undertaking by Purchaser or any of its Affiliates to purchase from Seller or any of its Affiliates all or part of the Purchased Assets,

or to enter or cause any person to enter in the Sub-License Agreement (as defined below), or be bound by any obligation of any nature

whatsoever in connection with the Contemplated Transaction other than those obligations expressly set forth in this Call Option Letter.

1.3 Subject to delivery of the Call Option Exercise Notice in accordance with this Call Option Letter, Seller

undertakes to execute the IP Purchase Agreement simultaneously with Purchaser and the Sub-License Agreement with Joint Venture, each on

the Effective Date (as defined below), provided that, Purchaser shall have the right to elect to defer execution of the Sub-License Agreement

by each party thereto, to a date (the “Execution Date”) to be specified by Purchaser in writing at least ten (10) Business

Days prior to the Execution Date, provided that the Execution Date is no later than five (5) years after the Call Option Date. Any such

deferral shall be communicated to Seller in the Call Option Exercise Notice.

1.4 This Call Option Letter and the grant of the Call Option is irrevocable until the Expiry Date.

1.5 The Parties shall use reasonable best efforts to negotiate

and agree a new license agreement with respect to the Acquired IP (as defined under the IP Purchase Agreement) between Purchaser, as

licensor and Trina Solar Co., Ltd, as licensee (the “New License Agreement”), prior to the Effective Date, which shall

be executed on the Effective Date. For the avoidance of doubt, the agreement and execution of the New License Agreement shall not be

a condition to the exercise of the Call Option or the execution of, or completion under, the IP Purchase Agreement.

2. DURATION OF THE CALL OPTION

2.1 The Call Option shall be exercisable by Purchaser by serving a Call Option Exercise Notice (as defined

below) on Seller (in accordance with Sections 2.2 and 2.3) on a Business Day (the “Call Option Date”)

during the period beginning on the date hereof and ending thirty (30) days following the date hereof (the “Expiry Date”).

2.2 If Purchaser wishes to exercise the Call Option, it shall do so by sending to Seller a notice substantially

in the form attached hereto as Schedule B (the “Call Option Exercise Notice”).

19

2.3 To be valid, the Call Option Exercise Notice:

(a) shall be signed by a duly authorized representative of Purchaser;

(b) shall specify the time and date (the “Effective Date”),

being a Business Day no less than two (2) Business Days and no more than five (5) Business Days after the date of delivery of the Call

Option Exercise Notice, on which each of Seller and Purchaser shall deliver a counterpart of the IP Purchase Agreement duly executed

by it and Seller and subject to the JV Establishment (as defined below) having occurred, Joint Venture shall enter into the Sub-License

Agreement unless deferred by Purchaser and subject to Section 4; and

(c) shall be issued no later than the Expiry Date.

2.4 If the Call Option Exercise Notice has not been issued prior to the Expiry Date, this Call Option Letter

shall expire automatically, without any obligation or liability, in contract, tort or otherwise, of any party, its Affiliates or any of

their respective directors, officers, employees or advisers.

2.5 The validity and enforceability of the Call Option is not subject to the execution of the IP Purchase

Agreement and accordingly, upon exercise of the Call Option, Purchaser shall be bound under the IP Purchase Agreement as from the Effective

Date irrespective of whether or not the IP Purchase Agreement has been executed by Purchaser.

2.6 The validity and enforceability of the Call Option is not subject to the grant of the Sub-License or the

execution of the Sub-License Agreement and accordingly, upon exercise of the Call Option, Seller shall be bound to grant the Sub-License

and enter into the Sub-License Agreement as from the Effective Date on the Execution Date as is identified by the Purchaser in accordance

with Section 1.3, subject to Section 4.

3. ConSIDERATION FOR THE CALL OPTION and the contemplated transaction

3.1 In consideration for the grant of the Call Option, Purchaser shall pay to Seller an amount of $2,000,000

in cash (the “Option Premium”) within two (2) Business Days of the date hereof, by wire transfer of immediately available

funds to Seller’s account, details of which are set forth under Schedule C hereto (the “Seller Account”).

The Option Premium shall be non-refundable in all circumstances, including if the Call Option is not exercised or lapses on the Expiry

Date.

3.2 If the Call Option is exercised, the aggregate purchase price for the Contemplated Transaction, in addition

to the Option Premium, shall be $133,000,000 (the “Purchase Price”) payable by Purchaser in four tranches:

(a) First tranche of the Purchase Price shall be equal to $60,000,000 (the “First Tranche Purchase

Price”), payable by the date falling three (3) Business Days after the Closing Date (as defined in the IP Purchase Agreement

and such payment date, the “First Payment Date”) and satisfied, at Purchaser's sole discretion (with respect to (i)

and (ii)) and notified to Seller in the Call Option Exercise Notice, either (i) in cash, by wire transfer of immediately available funds

to the Seller Account or (ii) by the issuance to Seller, subject to Section 3.3(i), of a number of shares of Purchaser Common

Stock equal to the quotient of (x) First Tranche Purchase Price divided by (y) Purchaser Stock Price determined as of the First

Payment Date, rounded down to the nearest whole share, or (iii) any combination of the foregoing in such ratio as mutually agreed to by

the parties (such shares of Purchaser Common Stock issued, together with any shares of Purchaser Common Stock issued pursuant to Sections

3.2(b), 3.2(c) and 3.2(d) the “Consideration Shares”).

20

(b) Second tranche of the Purchase Price shall be equal to $25,000,000 (the “Second Tranche Purchase

Price”), payable on September 30, 2026 (the “Second Payment Date”) and satisfied, at Purchaser's sole discretion

(with respect to (i) and (ii)) and notified to Seller in writing at least five (5) Business Days prior to the Second Payment Date, either

(i) in cash, by wire transfer of immediately available funds to the Seller Account or (ii) by the issuance to Seller, subject to Section

3.3(i), of a number of shares of Purchaser Common Stock equal to the quotient of (x) Second Tranche Purchase Price divided

by (y) Purchaser Stock Price determined as of the Second Payment Date, rounded down to the nearest whole share, or (iii) any combination

of the foregoing in such ratio as mutually agreed to by the parties.

(c) Third tranche of the Purchase Price shall be equal to $30,000,000 (the “Third Tranche Purchase

(with respect to (i) and (ii)) and notified to Seller in writing at least five (5) Business Days prior to the Third Payment Date, either

(i) in cash, by wire transfer of immediately available funds to the Seller Account or (ii) by the issuance to Seller, subject to Section

3.3(i), of a number of shares of Purchaser Common Stock equal to the quotient of (x) Third Tranche Purchase Price divided by

(y) Purchaser Stock Price determined as of the Third Payment Date, rounded down to the nearest whole share, or (iii) any combination of

the foregoing in such ratio as agreed to by the parties.

(d) Fourth tranche of the Purchase Price shall be equal to $18,000,000 (the “Fourth Tranche Purchase

Price”), payable on October 30, 2026 (the “Fourth Payment Date”) and satisfied, at Purchaser's sole discretion

(with respect to (i) and (ii)) and notified to Seller in writing at least five (5) Business Days prior to the Fourth Payment Date, either

(i) in cash, by wire transfer of immediately available funds to the Seller Account or (ii) by the issuance to Seller, subject to Section

3.3(i), of a number of shares of Purchaser Common Stock equal to the quotient of (x) Fourth Tranche Purchase Price divided

by (y) Purchaser Stock Price determined as of the Fourth Payment Date, rounded down to the nearest whole share, or (iii) any combination

of the foregoing in such ratio as mutually agreed to by the parties.

3.3 The Consideration Shares shall be issued on the terms and subject to the provisions set forth below:

(a) Where Purchaser elects, in accordance with Section 3.2,

to satisfy all or any portion of any tranche of the Purchase Price by the issuance of shares of Purchaser Common Stock, Purchaser shall,

on the applicable Payment Date, instruct the Transfer Agent to issue and deliver to Seller the number of shares of Consideration Shares

determined in accordance with Section 3.2, in uncertificated, book-entry form.

(b) Seller acknowledges and agrees that neither the issuance of

the Consideration Shares hereunder nor the transfer of such shares to Seller has been registered under the Securities Act, and they will

be offered and sold to Seller pursuant to an exemption from the registration provisions of the Securities Act which depends upon, among

other things, the bona fide nature of the investment intent of Seller and the accuracy of Seller’s representations as expressed

herein. Seller understands that the Consideration Shares are “restricted securities” under applicable U.S. federal and state

securities laws and that, pursuant to these laws, Seller must hold the Consideration Shares indefinitely unless and until they are registered

with the SEC and qualified by state authorities, or an exemption from such registration and qualification requirements is available.

Seller acknowledges that if an exemption from registration or qualification is available, it may be conditioned on various requirements

including the time and manner of sale, the holding period for the Consideration Shares, and on requirements relating to Purchaser which

are outside of Seller’s control, which Purchaser is under no obligation, and may not be able, to satisfy.

21

(c) Seller understands and agrees that Consideration Shares may

not be sold or otherwise transferred, except pursuant to an effective registration under the Securities Act, or in a transaction which

qualifies as an exempt transaction under the Securities Act and the rules and regulations promulgated thereunder and in accordance with

the restrictions set forth in this Agreement.

(d) Seller acknowledges that each certificate or instrument evidencing the Consideration Shares shall initially

bear substantially the following restrictive legend, either as an endorsement, on the face thereof or a comparable notation or other arrangement

with respect to any uncertificated shares:

“THIS SECURITY

HAS BEEN ACQUIRED FOR INVESTMENT AND WITHOUT A VIEW TO DISTRIBUTION AND HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 (THE

“ACT”), OR UNDER STATE SECURITIES LAWS. NO TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER DISPOSITION OF THIS

SECURITY OR ANY INTEREST OR PARTICIPATION THEREIN MAY BE MADE EXCEPT (A) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE ACT

OR (B) PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS AND, IN THE CASE OF CLAUSE (B), UNLESS

THE ISSUER RECEIVES AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT REGISTRATION IS NOT REQUIRED

UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS.”

(e) On or prior to each Payment Date on which Consideration Shares are to be issued, Purchaser shall have

received official notice from the NYSE of its approval of the issuance in respect of the Consideration Shares to be issued on such Payment

Date, and shall take all other actions required so that such Consideration Shares are, upon issuance, listed and authorized for trading

on the NYSE. Purchaser shall not issue any Consideration Shares unless, upon issuance, such shares are so listed and authorized. If any

shares of Purchaser Common Stock become issuable under this Agreement in excess of the number covered by the authorization referred to

herein, Purchaser shall file such supplemental listing application(s), and obtain such further authorization, as may be required prior

to the issuance thereof.

(f) Purchaser agrees that as soon as practicable but in no event later than five (5) Business Days following

each Payment Date on which Consideration Shares are to be issued (each a “Filing Date”), Purchaser will file with the

SEC under the Securities Act, at the Purchaser’s sole cost and expense, a registration statement, or a prospectus supplement to

the prospectus included in an existing registration statement, covering the resale by Seller of the number Consideration Shares issuable

to Seller on such Payment Date (such Consideration Shares, the “Registrable Securities” and such registration statement

or prospectus supplement, the “Registration Statement”); provided, however, that Purchaser’s obligations

to include the Registrable Securities in the Registration Statement are contingent upon Seller furnishing a completed and executed selling

securityholder questionnaire in customary form to Purchaser that contains the information regarding Seller, the securities of Purchaser

held by Seller and the intended method of disposition of the Registrable Securities (which shall be limited to non-underwritten public

offerings)required by SEC rules for inclusion in the Registration Statement to effect the registration of the Registrable Securities,

and Seller shall execute such documents in connection with any such registration as Purchaser may reasonably request that are customary

of a selling securityholder in similar situations. For purposes of clarification, any failure by Purchaser to file the prospectus supplement

by any Filing Date shall not otherwise relieve Purchaser of its obligations to file a prospectus supplement as set forth above in this

section. Unless required under applicable laws and SEC rules, in no event shall Seller be identified as a statutory underwriter in any

Registration Statement; provided, that if Seller is required to be so identified as a statutory underwriter

in a Registration Statement, Seller will have an opportunity to withdraw its Registrable Securities from such Registration Statement.

To the extent any Registration Statement must be declared effective, Purchaser shall use its commercially reasonably efforts to cause

such Registration Statement to be declared effective by the SEC as promptly as practicable, but in no event later than thirty (30) calendar

days following the applicable Payment Date (or sixty (60) calendar days in the event of a full review by the SEC) (the “Effectiveness

Deadline”).

22

(g) Purchaser shall use its commercially reasonable efforts to

keep such registration, and any qualification, exemption or compliance under state securities laws which Purchaser determines to obtain,

continuously effective with respect to Seller, and to keep the applicable Registration Statements or any subsequent shelf registration

statement free of any material misstatements or omissions, until the earlier of the following: (i) Seller ceases to hold any Registrable

Securities and (ii) the date all Registrable Securities held by Seller may be sold without restriction under Rule 144, including without

limitation, any volume and manner of sale restrictions which may be applicable to affiliates under Rule 144 and without the requirement

for Purchaser to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable).

(h) Notwithstanding anything herein to the contrary, Purchaser may suspend the use of any prospectus (a “Prospectus”)

included in any Registration Statement contemplated by this Section 3.3 in the event that the Purchaser’s board of directors

determines in good faith that such suspension is necessary to (A) delay the disclosure of material non-public information concerning Purchaser,

the disclosure of which at the time is not, in the good faith opinion of the Purchaser’s board of directors, in the best interests

of the Purchaser or (B) amend or supplement the affected Registration Statement or the related Prospectus so that such Registration Statement

or Prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein

or necessary to make the statements therein, in the case of the Prospectus in light of the circumstances under which they were made, not

misleading (an “Allowed Registration Delay”); provided, that Purchaser shall promptly (a) notify Seller

in writing of the commencement of and the reasons for an Allowed Registration Delay, but shall not (without the prior written consent

of Seller) disclose to Seller any material non-public information giving rise to an Allowed Registration Delay, (b) advise Seller in writing

to cease all sales under the Registration Statement until the end of the Allowed Registration Delay and (c) use commercially reasonable

efforts to terminate an Allowed Registration Delay as promptly as practicable provided, however, that Purchaser shall not be entitled

to exercise an Allowed Registration Delay (i) more than twice in any twelve (12) month period, (ii) for a period exceeding thirty (30)

consecutive days on any single occasion, or (iii) for an aggregate of more than sixty (60) days in any twelve (12) month period.

23

(i) For the avoidance of doubt, the total number of Consideration Shares hereunder shall not exceed 19.9%

of the total number of shares of Purchaser Common Stock issued and outstanding as of the date hereof and if the Consideration Shares would

exceed 19.9% of the total number of shares of Purchaser Common Stock, the remainder of the Purchase Price shall be paid in cash.

(j) The Purchaser agrees that it shall render any reasonably necessary

assistance to the Seller to ensure the Seller receives freely tradable shares, including, without limitation, assisting the Seller in

transferring such shares from its transfer agent account to its designated broker account. Further, the Purchaser shall use its commercially

reasonably efforts to timely provide, or cause its counsel to provide, any legal opinions, Medallion signature guarantee waivers, and

any other documents, instruments, or information reasonably requested or required by the transfer agent to effectuate such transfer and

issuance, upon the Seller’s reasonable request.

3.4 Payment in full of each tranche of the Purchase Price in accordance with Section 3.2 (including,

where satisfied in whole or in part by the issuance of Consideration Shares, the issuance and delivery of the number of shares determined

in accordance with the applicable provision of Section 3.2 into Seller’ account with Purchaser’s transfer agent) shall

constitute full and final satisfaction and discharge of Purchaser's obligation in respect of such tranche, provided, however, that such

discharge shall not relieve Purchaser of its ongoing obligations under Section 3.3 with respect to such Consideration Shares.

3.5 The Option Premium and Purchase Price shall be paid free and clear of, and without deduction or withholding

for or on account of, withholding Taxes unless Purchaser is required applicable Law to make any such deduction or withholding. If any

deduction or withholding for or on account of Taxes is required by applicable Law from the Option Premium and Purchase Price, Purchaser

shall pay (or cause to be paid) to Seller such additional amount as will ensure that the net amount Seller receives equals the full amount

which it would have received had the deduction or withholding (and any deduction or withholding applicable to such additional amount)

not been required. Where any portion of the Option Premium and Purchase Price is satisfied by the issuance of Consideration Shares, Purchaser

shall not reduce the number of Consideration Shares issuable in respect of such portion on account of any required deduction or withholding

of any Taxes, and shall instead remit to the relevant Taxing Authority, in cash and for its own account, the full amount required to be

deducted or withheld in respect of such portion (as increased pursuant to this Section 3.5), and such remittance shall satisfy

Purchaser's obligations under this Section 3.5 in respect of such deduction or withholding. To the extent that Purchaser believes

withholding Taxes shall apply, Purchaser shall give Seller notice thereof and Purchaser and Seller shall work together in good faith to

mitigate such withholding (including the provision of any documentation reasonably requested by Purchaser pursuant to Section 3.7

that will permit payments made pursuant to this Agreement to be made without withholding or at a reduced rate of withholding). Notwithstanding

anything to the contrary in this Section 3.5, no Tax gross-up shall be made for any payment for which Seller fails to provide reasonably

requested documentation that, if provided, would have eliminated or reduced the rate of withholding.

3.6 If Seller receives or is granted a refund, credit or repayment in respect of Taxes for which Purchaser

has paid an additional amount under Section 3.5 (or a credit against Taxes otherwise payable by it attributable to the relevant

deduction or withholding), Seller shall, promptly upon receipt or utilization, pay to Purchaser an amount equal to the lesser of (i) such

refund, credit or repayment (net of reasonable out-of-pocket costs of obtaining it and any Taxes imposed on its receipt) and (ii) the

additional amounts paid by Purchaser under Section 3.5 in respect of the relevant deduction or withholding, in each case such that

Seller is left in no better and no worse an after-Tax position than it would have been in had no such deduction or withholding been required.

Seller shall use commercially reasonable efforts to claim any refund, credit or repayment reasonably identified to it by Purchaser.

24

3.7 Seller shall provide Purchaser with all applicable tax documentation reasonably requested by Purchaser

on the date hereof, including a valid and properly executed Internal Revenue Service Form W-9, Form W-8BEN-E, or any other form or information

reasonably necessary to establish an exemption from, or reduction in, any applicable withholding tax obligations.

3.8 Any tranche of the Purchase Price that is not paid on the applicable Payment Date, including if the Acceleration

Amount is not paid on the Acceleration Date, shall accrue interest beginning the day after such Payment Date and continue until Seller

receives the full payment, at a rate of two percent (2%) per month, calculated daily on the basis of the actual number of days elapsed,

or the highest rate permitted by Law, whichever is less (the “Default Interest”).

3.9 If Purchaser fails to pay any tranche of the Purchase Price on the applicable Payment Date and Purchaser

does not pay such amount by the date falling five (5) Business Days after the applicable Payment Date (“Acceleration Date”),

any and all outstanding tranches of the Purchase Price, including any Default Interest calculated in accordance with Section 3.8

(together, the “Acceleration Amount”), shall become immediately due and payable.

3.10 For the purposes of this Section 3, the following capitalized terms shall have the meanings ascribed

to them below:

(a) “NYSE” means New York Stock Exchange.

(b) “Payment Date” means any of the First Payment Date, Second Payment Date, Third Payment

Date or Fourth Payment Date.

(c) “Purchaser Common Stock” means the common stock, par value $0.01 per share, of Purchaser.

(d) “Purchaser Stock Price” means the product of (i) 0.85, and (ii) VWAP over the five

(5) full consecutive trading days ending two (2) Business Days prior to the applicable date of determination.

(e) “SEC” means Securities and Exchange Commission.

(f) “Securities Act” means the Securities Act of 1933, as amended.

(g) “Tax” means any income, alternative or add-on minimum tax, gross income, estimated,

payroll, social security (or equivalent, including employer and employees’ contributions), employment, unemployment, disability,

excise, severance, stamp, occupation, premium, property (real, tangible or intangible), environmental or windfall profit tax, escheat

or unclaimed property, custom duty, tariff, or other tax, governmental fee or other like assessment or charge in the nature of a tax,

together with any interest or any penalty or addition to tax or additional amount (whether disputed or not) imposed by any Governmental

Authority responsible for the imposition of any such tax (domestic or foreign).

25

(h) “Taxing Authority” means any Governmental Authority having or purporting to exercise

jurisdiction with respect to any Tax, including with respect to the imposition, interpretation, assessment, or collection of any Tax.

(i) “VWAP” means the dollar volume–weighted average price for the shares of Purchaser

official close of trading), as reported by Bloomberg, L.P . through its “Volume at Price” function or if the foregoing does

not apply, the dollar volume–weighted average price of such security in the over-the-counter market on the electronic bulletin board

for such security during the period beginning at 9:30:01 a.m., New York time (or such other time as the NYSE publicly announces is the

official open of trading), and ending at 4:00:00 p.m., New York time (or such other time as the NYSE publicly announces is the official

close of trading), as reported by Bloomberg, L.P . If the VWAP cannot be calculated for the shares of Purchaser Common Stock on a particular

date on any of the foregoing basis, the VWAP of the shares of Purchaser Common Stock shall be the fair market value of the shares of Purchaser

Common Stock on such date as determined by Purchaser ’s board of directors in good faith.

4. Joint Venture Matters

4.1 From the date hereof until the Expiry Date, Parties shall negotiate in good faith to establish a joint

venture for the purposes of pursuing battery energy storage system (“BESS”) projects and opportunities outside of the

United States and holding the Sub-License, on terms set forth in this Section 4 and otherwise on terms reasonably acceptable to

both Parties.

4.2 Parties agree that Joint Venture shall be established through Photon Solar Pte. Ltd., a company established

under the laws of Singapore (“Joint Venture”), by way of the transfer by Seller to Purchaser, as part of the Contemplated

Transaction and for no additional consideration, of 90% of the issued and outstanding shares of Joint Venture, such that, upon completion

of such transfer (the “JV Establishment”), Purchaser shall own 90% and Seller shall own 10% of the issued and outstanding

shares of Joint Venture. At or prior to the JV Establishment, Parties shall enter into a shareholders' agreement in respect of the Joint

Venture on terms reasonably acceptable to both Parties. JV Establishment shall be subject to completion of due diligence by Purchaser,

satisfactory to Purchaser, in its sole discretion.

4.3 Conditional upon JV Establishment, Seller shall (i) subject to delivery of the Call Option Exercise Notice

in accordance with this Call Option Letter, grant to Joint Venture a royalty-free, fully paid-up, worldwide, irrevocable, sub-licensable

sub-license under the license granted to Seller pursuant to the 5GW License (the “Sub-License”), for the activities

licensed under the 5GW License pursuant to a sublicense agreement reasonably acceptable to Purchaser (the “Sub-License Agreement”)

and in accordance with Section 1.3, including the potential deferral contemplated thereunder, and (ii) contribute, or cause to

be contributed, to the Joint Venture such projects and opportunities in the BESS industry as Parties may agree in writing, on terms to

be agreed between Parties.

4.4 For the avoidance of doubt, the execution of the Sub-License Agreement shall be subject to and conditional

upon the JV Establishment having occurred, provided that Purchaser’s delivery of the Call Option Exercise Notice shall not be, in

any way, conditional upon this Section 4; in the event that the Call Option Exercise Notice is delivered before the JV Establishment,

the Purchaser shall defer the execution of the Sub-License in accordance with Section 1.3.

26

4.5 Seller shall use its best efforts to negotiate and adopt, as soon as practicable following the date hereof,

such amendments to the 5GW License as may be reasonably requested by Purchaser (including such amendments that in Purchaser’s reasonable

discretion are necessary to comply with applicable Laws). Seller shall (i) consult with Purchaser and keep Purchaser reasonably informed

of the status of such negotiations, (ii) consider drafts from Purchaser and provide Purchaser with drafts of any proposed amendments to

5GW License reasonably in advance of their adoption, and (iii) not agree to, adopt or permit any amendment, waiver, termination or assignment

of, or under, 5GW License, without Purchaser's prior written consent.

4.6 Purchaser may, at any time, in its sole discretion, by written notice to Seller (a “Sub-License

Abandonment Notice”), elect to abandon the Sub-License, whereupon, with effect from the date of the Sub-License Abandonment

Notice: (i) all obligations of the Parties with respect to the 5GW License, grant of the Sub-License and the execution and delivery of

the Sub-License Agreement, shall terminate and be of no further force or effect; and (ii) Purchaser's right to defer execution of the

Sub-License, and the Sub-License Execution Date, shall lapse. For the avoidance of doubt, the delivery of a Sub-License Abandonment Notice

shall not affect (x) the JV Establishment or any other obligation of the Parties under this Section 4 (other than as set forth

in this Section 4.6), (y) the Call Option, the Contemplated Transaction or the IP Purchase Agreement, or (z) the amount or timing

of payment of the Purchase Price.

5. EXCLUSIVITY

By countersigning this Call Option Letter,

Seller undertakes for the duration of the Call Option not to take any action to, and to procure (so far as it lies within its powers)

that the Affiliates of Seller do not, until the Expiry Date:

(a) enter into any contract, arrangement or understanding for selling, or take any other action to transfer,

by any means (including by sale, lease, merger, contribution, disposal, reorganization or otherwise), all or part of the Purchased Assets

or other than the Contemplated Transaction (any of the foregoing being referred to as an “Alternative Sale Transaction”);

(b) enter into any contract, arrangement or understanding for sublicensing the license under the 5GW License,

other than the Contemplated Transaction (an “Alternative Sublicense Transaction”, together with the Alternative Sale

Transaction, an “Alternative Transaction”); or

(c) initiate, solicit, pursue or participate in, any discussions or negotiations that constitute, solicit

or encourage an Alternative Transaction.

6. REPRESENTATIONS AND WARRANTIES

6.1 Each party represents and warrants to the other, in respect of itself, that:

(a) it is duly organized and validly existing under the Laws of the jurisdiction in which it is organized;

(b) it has the power and authority to enter into this Call Option Letter and to perform its obligations hereunder;

(c) the execution of this Call Option Letter has been duly authorized by all relevant corporate bodies and

no other corporate action is necessary on its part to authorize the execution of this Call Option Letter; and

(d) this Call Option Letter has been duly executed by it on the date hereof and constitutes legal, valid and

binding obligations upon it, enforceable against it in accordance with its terms.

27

6.2 Seller hereby represents and warrants to Purchaser as of the date hereof and as of the Closing Date, that:

(a) Seller is an “institutional accredited investor” as defined in Rule 501(a)(1), (2), (3) or

(7) under the Securities Act (the “Institutional Accredited Investors”). Seller acknowledges that it is informed as

to the risks of the ownership of the Consideration Shares and has such knowledge and experience in financial and business matters that

it is capable of evaluating the merits and risks of such ownership, and is able to bear the economic risk of such ownership for an indefinite

period of time. Seller has been furnished access to such information and documents as it has requested and has been afforded an opportunity

to ask questions of and receive answers from representatives of Purchaser concerning the issuance of the Consideration Shares; and

(b) Seller (i) is acquiring the Consideration Shares only for its own account or for one or more separate

accounts maintained by it for the benefit of one or more other Institutional Accredited Investors and not with a view to the distribution

thereof in violation of the securities laws, provided that the disposition of such Purchaser’s property shall at all times

be within such Purchaser’s control, and (iii) is not acquiring the Consideration Shares with a view to, or for offer or sale in

connection with, any distribution thereof in violation of the Securities Act or other applicable securities laws. Seller acknowledges

and agrees that the Consideration Shares are being offered in a transaction not involving any public offering within the meaning of the

Securities Act and that the Securities have not been registered under the Securities Act and that Purchaser is not required to register

Exhibit 99.1

News

Release

T1 Announces Acquisition of Advanced

Solar Intellectual Property Rights from Evervolt

AUSTIN,

Texas and NEW YORK, July 28, 2026 -- T1 Energy Inc. (NYSE: TE) (“T1,” “T1 Energy,” or the “Company”)

announced this morning that it has acquired foundational solar patents and other intellectual property

(“IP”) and other assets from Singapore-based Evervolt Green Energy Holding Pte Ltd. (“Evervolt”) for a total

consideration of $135 million. The patents, which T1 had previously licensed from Evervolt, relate to Tunnel Oxide Passivated Contact

(“TOPCon”) solar cells and modules, which T1 believes is the most advanced, highly efficient commercially viable solar technology

available.

Under the agreed

terms of the transaction, T1 initially paid $2 million in cash to secure the right to acquire the IP and other assets. The remaining

$133 million purchase price is payable in four installments: (i) $60 million due

within three business days of closing on July 28, 2026 (the “First Tranche”), (ii) $25 million due September 30, 2026, (iii)

$30 million due October 15, 2026, and (iv) $18 million due October 30, 2026. T1 currently intends to satisfy the First Tranche by the

issuance of shares of T1 common stock. Each installment subsequent to the First Tranche is payable, at T1’s sole election, in cash or

shares of T1 common stock or a combination thereof. Any issuance of T1 common stock would be done at a 15% discount to a five trading

day volume weighted average trading price during a window ending prior to the date of issuance.

“Owning the

intellectual property rights to leading silicon-based solar technologies is an important step to differentiate T1’s competitive

position as a vertically integrated crystalline silicon U.S. solar manufacturer,” commented Dan Barcelo, Chairman and CEO of T1

Energy. “We also believe that this intellectual property will be accretive to T1 economically in addition to yielding significant

commercial and strategic benefits.”

The

acquisition of the IP provides an important economic benefit to T1, as it eliminates future royalty payments now that T1 owns and

controls the IP it previously licensed from Evervolt. This acquisition advances T1’s strategy to build America’s first

fully integrated domestic silicon-based solar supply chain.
