Following the closing of the Business Combination (the “Closing”), in addition to the consideration to be received pursuant to the Share Exchange, if at any time during the period beginning on the date of the Closing (the “Closing Date”) and ending on the fifth anniversary thereof (the “Earn-Out Period”), the closing price of the PubCo Class A Ordinary Shares equals or exceeds certain specified price thresholds for any twenty (20) consecutive Trading Days (as defined in the Business Combination Agreement) (each such threshold, an “Earn-Out Target”), then within ten (10) Trading Days following the achievement of such Earn-Out Target, PubCo will issue to the Sellers an aggregate of 7,500,000 PubCo Class A Ordinary Shares for each Earn-Out Target achieved, in an amount of shares equal to each Seller’s pro rata portion of the ThomasLloyd ordinary shares exchanged in the Share Exchange (such PubCo Class A Ordinary Shares issuable upon achievement of the Earn-Out Targets, the “Earn-Out Consideration”).

The PubCo Equity Incentive Plan will provide for the issuance of shares equal to up to 10% of the PubCo Shares on a fully-diluted basis (calculated after giving effect to the Transactions) and will include an annual automatic increase in the share reserve on the first day of each fiscal year, such increase up to 3% of the PubCo Shares on a fully-diluted basis. The PubCo ESPP will provide for the issuance of shares equal to 2% of the PubCo Shares on a fully-diluted basis (calculated after giving effect to the Transactions) and will include an annual automatic increase in the share reserve on the first day of each fiscal year of 1% of the PubCo Shares on a fully-diluted basis.

The Business Combination Agreement also contains obligations of Roman and PubCo to use their commercially reasonable efforts to seek financing agreements for an aggregate of at least $100 million in proceeds through one or more subscription agreements on such terms and conditions therein, and using a placement agent, to be mutually agreed by Roman, PubCo and ThomasLloyd. Each of Roman, PubCo and ThomasLloyd will use commercially reasonable efforts to cooperate with each other in connection with the arrangement of any PIPE Financing (as defined in the Business Combination Agreement).

The initial director designees will hold such office until their respective successors are duly appointed and qualified or until their earlier death, resignation or removal.

If the Business Combination Agreement is validly terminated, none of the parties will have any liability or any further obligation under the Business Combination Agreement other than customary confidentiality obligations, except in the case of willful breach or fraud. Notwithstanding the foregoing, (i) if Roman terminates the Business Combination Agreement after June 30, 2026 solely due to ThomasLloyd’s failure to deliver the required audited financial statements by June 30, 2026, ThomasLloyd shall pay Roman the portion of Roman’s reasonable and documented out-of-pocket fees and expenses paid or payable to third parties as they relate to the negotiation of the Ancillary Agreement (as defined in the Business Combination Agreement) and the Business Combination Agreement (the “Roman Transaction Expenses”), (ii) if ThomasLloyd fails to consummate the Transactions upon satisfaction of all of the conditions to Closing as set forth in Article XI of the Business Combination Agreement (other than those conditions that by their nature would be satisfied at the Closing) or otherwise terminates the Business Combination Agreement in breach of Article XII of the Business Combination Agreement, provided in each case, that Roman and PubCo are each ready and willing to consummate the Transactions at such time and not in breach of their obligations, ThomasLloyd shall pay Roman the Roman Transaction Expenses plus $8,000,000 as liquidated damages as set forth in the Business Combination Agreement, or (iii) if either Roman or ThomasLloyd terminates the Business Combination Agreement because the Closing has not occurred by the Outside Closing Date (provided that such termination right is not available to a party whose failure to fulfill its obligations was the proximate cause of the failure to close), ThomasLloyd shall pay Roman the Roman Transaction Expenses plus $8,000,000 as liquidated damages as set forth in the Business Combination Agreement.

The Business Combination Agreement contains representations, warranties and covenants that the respective parties made to each other as of the date of such agreement or other specific dates. The assertions embodied in those representations, warranties and covenants were made for purposes of the contract among the respective parties and are subject to important qualifications and limitations agreed to by the parties in connection with negotiating such agreement.

Investors and security holders are not third-party beneficiaries under the Business Combination Agreement and should not rely on the representations, warranties, covenants and agreements, or any descriptions thereof, as characterizations of the actual state of facts or condition of any party to the Business Combination Agreement. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Business Combination Agreement, which subsequent information may or may not be fully reflected in Roman’s public disclosures.

The foregoing description of the Business Combination Agreement is qualified in its entirety by reference to the Business Combination Agreement filed as Exhibit 2.1 to this Current Report on Form 8-K.

Related Agreements

The Business Combination Agreement contemplates the execution of various additional agreements and instruments, on or before the Closing, including, among others, the following:

Sponsor Support Agreement

Concurrently with the execution of the Business Combination Agreement, Roman, Roman DBDR Acquisition Sponsor II LLC, a Delaware limited liability company (the “Sponsor”), and ThomasLloyd entered into the Sponsor Support Agreement, pursuant to which the Sponsor has agreed to, among other things, (i) vote in favor of the Business Combination Agreement, the Merger, and each other proposal related to the Transactions, and against any alternative transactions or agreements that would impede, hinder, interfere with, delay, postpone, frustrate, prevent or nullify the Transactions, (ii) not redeem any Subject Shares (as defined in the Sponsor Support Agreement) in connection with the Transactions, (iii) be bound by certain other covenants and agreements related to the Business Combination, (iv) be bound by certain transfer restrictions with respect to its shares in Roman prior to the expiration time of the Sponsor Support Agreement, (v) be subject to the restrictions contemplated by the Lock-Up Agreement, (vi) waive anti-dilution protections with respect to the conversion of Roman Class B ordinary shares, par value $0.0001 per share (“Roman Class B Shares”), (vii) convert each Roman Class B Share into one Roman Class A Share, in each case, on the terms and subject to the conditions set forth in the Sponsor Support Agreement, (viii) waive any appraisal rights to dissent from the Transactions, and (viii) not amend, terminate or modify the Insider Letter (as defined in the Sponsor Support Agreement) without ThomasLloyd’s prior written consent.

A copy of the Sponsor Support Agreement is filed with this Current Report on Form 8-K as Exhibit 10.1 and is incorporated herein by reference, and the foregoing description of the Sponsor Support Agreement is qualified in its entirety by reference thereto.

Registration Rights Agreement

In connection with the Transactions, PubCo, Roman, Sponsor, and certain shareholders of Roman and ThomasLloyd will enter into the Registration Rights Agreement. Pursuant to the Registration Rights Agreement, among other things, PubCo will agree that, within thirty (30) days following the Closing Date, PubCo will file with the SEC a registration statement registering the resale of certain PubCo Shares held by or issuable to the parties thereto (such registration statement, the “Resale Registration Statement”), and PubCo will use its commercially reasonable efforts to have the Resale Registration Statement declared effective as soon as reasonably practicable after the filing thereof, but no later than the earlier of (i) sixty (60) days following the filing (or ninety (90) days if the SEC reviews the registration statement) and (ii) seven (7) business days after the SEC notifies PubCo that the registration statement will not be reviewed. Such holders will be entitled to customary piggyback registration rights and demand registration rights, including underwritten demands. The Registration Rights Agreement also provides for liquidated damages payable to holders if PubCo fails to file or have declared effective the Resale Registration Statement within the required timeframes.

The Registration Rights Agreement amends and restates the registration rights agreement that was entered into by Roman, the Sponsor and B. Riley Securities, a Delaware corporation, in connection with Roman’s initial public offering.

The Registration Rights Agreement will terminate on the earlier of (a) the five year anniversary of the date of the Registration Rights Agreement or (b) with respect to any holder party thereto, on the date that such holder no longer holds any Registrable Securities (as defined therein).

The foregoing description of the Registration Rights Agreement is subject to and qualified in its entirety by reference to the full text of the form of Registration Rights Agreement, a copy of which is attached as Exhibit 10.2 hereto, and the terms of which are incorporated herein by reference.

Lock-Up Agreement

Pursuant to the Lock-Up Agreement, the Sponsor and certain ThomasLloyd shareholders will agree not to effect any transfer, sale or distribution (except for certain permitted transfers) of any PubCo Shares held by such holder after the Closing until the earlier of 180 days after the Closing Date or the date on which PubCo consummates a liquidation, merger, capital stock exchange, reorganization, or other similar transaction which results in all of the shareholders of PubCo having the right to exchange their PubCo Shares for cash, securities or other property.

The foregoing description of the Lock-Up Agreement is subject to and qualified in its entirety by reference to the full text of the form of Lock-Up Agreement, a copy of which is included as Exhibit 10.3 to this Current Report.

Amended and Restated Business Combination Marketing Agreement

In connection with the signing of the Business Combination Agreement, Roman, ThomasLloyd and B. Riley Securities, Inc. (“B. Riley”) entered into an Amended and Restated Business Combination Marketing Agreement (the “A&R BCMA”), which amended and restated the Business Combination Marketing Agreement, dated December 12, 2024, by and between Roman and B. Riley.

Pursuant to the A&R BCMA, B. Riley will provide certain advisory, marketing and capital markets services to Roman in connection with certain business combinations, including the Business Combination. As consideration for such services, Roman has agreed to pay B. Riley a fee equal to 4.5% of the gross proceeds received by Roman from the sale of its equity securities in its initial public offering, including any proceeds from the full or partial exercise of the underwriters’ over-allotment option (the “Fee”). In connection with the Business Combination, the Fee will be structured and calculated based on the gross proceeds available to PubCo at the Closing, including proceeds retained from the trust account following the redemption deadline, proceeds from any PIPE Financing and proceeds from any other sources (collectively the “Gross Proceeds”) as follows: 30% of the Gross Proceeds on the first $10.0 million of Gross Proceeds; 10% of the incremental Gross Proceeds exceeding $10.0 million, up to the total amount of the Fee.

If all or any portion of the Fee is not paid in full at Closing, PubCo is obligated to enter into a committed equity facility (the “CEF”) with B. Riley or its affiliate immediately upon the Closing, as described below. If the Fee has not been paid in its entirety at Closing or subsequent to the Closing, subject to certain conditions, Roman has agreed to maximize its use of the CEF, subject to customary ownership and volume limitations, and to pay B. Riley 30% of the net proceeds raised under the CEF until the Fee is paid in full. If the Fee has not been paid in full by the twelve-month anniversary of the Closing, PubCo will be required to pay the remaining unpaid balance in cash.

In addition, PubCo has granted B. Riley the right to serve in the following capacities in certain capital markets transactions: (1) as lead distribution agent for any at-the-market offering (with a commission of 2.0% of gross proceeds) for 24 months following the Closing, and (2) until the Fee is paid in full, as joint lead underwriter and joint lead bookrunner for any public offerings (with equal economics to other joint lead underwriters) and placement agent for any private offerings.

The foregoing description of the A&R BCMA is subject to and qualified in its entirety by reference to the full text of the A&R BCMA, a copy of which is filed as Exhibit 10.4 to this Current Report.

Item 7.01

Regulation FD Disclosure.

On February 27, 2026, Roman and ThomasLloyd issued a press release announcing the Business Combination. The press release is attached hereto as Exhibit 99.1 and incorporated by reference herein.

Attached as Exhibit 99.2 and incorporated by reference herein is an investor presentation, dated December 2025. Such investor presentation contains unaudited prospective financial information of ThomasLloyd (the “Projections”). ThomasLloyd does not, as a matter of course, publicly disclose projections as to future revenues, earnings, financial condition, cash flows or other operating results. The Projections were prepared by ThomasLloyd’s management solely for internal use and for use in connection with discussions with certain potential investors in a potential financing transaction.

The Projections were prepared as of a prior date and speak only as of that date. They were based on numerous assumptions and estimates reflecting management’s judgment at the time, including, among other things, assumptions regarding market conditions, operating performance, timing and availability of financing (including the assumption that financing of US $30–50 million would be raised prior to January 31, 2026), capital expenditures and other matters. Many of these assumptions are inherently uncertain, are beyond ThomasLloyd’s control, and are subject to significant business, economic, competitive and regulatory risks. Since the date the Projections were prepared, material changes in circumstances, market conditions, strategy, financing assumptions and other factors have occurred, and certain assumptions underlying the Projections are no longer accurate.

The Projections do not reflect subsequent events, updated information or revised assumptions, and have not been updated or revised to reflect current conditions. Neither Roman nor ThomasLloyd makes any representation or warranty, express or implied, as to the accuracy, completeness, reasonableness, achievability or reliability of the Projections, and neither Roman nor ThomasLloyd intends to, and expressly disclaims any obligation to, update, revise or reaffirm the Projections to reflect events or circumstances occurring after the date they were prepared, except as may be required by applicable law.

The Projections are being furnished to investors with this Form 8-K solely because they were previously made available to certain potential investors in connection with prior discussions regarding a potential financing transaction. Investors should not rely on the fact that Roman is furnishing the Projections with this Form 8-K as an indication that Roman or its management, ThomasLloyd or its management, or any other person considers the Projections to be predictive of future events or otherwise indicative of actual future results. Investors should not rely upon the Projections as public guidance, as predictive of future events, or as a basis for any investment decision.

The information in this Item 7.01, including Exhibit 99.1 and Exhibit 99.2, is furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to liabilities under that section, and shall not be deemed to be incorporated by reference into the filings of Roman under the Securities Act or the Exchange Act, regardless of any general incorporation language in such filings. This Current Report on Form 8-K will not be deemed an admission as to the materiality of any information in this Item 7.01, including Exhibit 99.1 and Exhibit 99.2.

Item 8.01

Other Events.

Committed Equity Facility Term Sheet

In connection with the consummation of the Transactions, Roman, ThomasLloyd and B. Riley entered into a binding term sheet (the “CEF Term Sheet”) with B. Riley relating to the CEF. Pursuant to the CEF Term Sheet, subject to the consummation of the Business Combination and the execution of definitive documentation, B. Riley will agree to purchase, from time to time during the 36-month commitment period following closing, up to an aggregate of $200.0 million (the “Aggregate Commitment Amount”) of PubCo’s common stock, at a purchase price equal to 97.0% of the volume-weighted average price of PubCo’s common stock during a defined pricing period, subject to customary ownership, exchange cap and volume limitations. In consideration for the Investor’s commitment, PubCo will agree to pay the Investor a commitment fee of 1.0% of the Aggregate Commitment Amount and to reimburse certain expenses, up to $75,000, not including quarterly legal fees of up to $7,500 in quarters where the CEF is used. If the engagement of a qualified independent underwriter (“QIU”) is required, PubCo will reimburse B. Riley up to an additional $55,000 for such engagement. The CEF Term Sheet is subject to customary conditions, including the negotiation of a definitive purchase agreement.

Additional Information about the Business Combination and Where to Find It

Forward-looking statements generally are accompanied by words such as “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “should,” “would,” “plan,” “predict,” “potential,” “seem,” “seek,” “future,” “outlook” and similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding expectations relating to the Business Combination and other related transactions, including potential benefits, anticipated timing and satisfaction of closing conditions of the Business Combination; the implied equity value of ThomasLloyd; the formation, future financial condition and performance of PubCo; expected financial impacts of the Business Combination, including the amount and timing of the anticipated PIPE raise; the level of redemptions of Roman shareholders; the expected future performance of PubCo; ThomasLloyd’s estimates and forecasts of its pipeline projects and market opportunities; ThomasLloyd’s anticipated capital expenditures; ThomasLloyd’s expectations related to the success of its project development activities; and ThomasLloyd’s beliefs regarding its position in energy markets, including with respect to AI and data centers. These statements are based on various assumptions, whether or not identified in this Current Report on Form 8-K, and on the current expectations of ThomasLloyd’s and Roman’s management and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as and must not be relied on by an investor as a guarantee, an assurance, a prediction, or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and may differ from assumptions. Many actual events and circumstances are beyond the control of ThomasLloyd and Roman. These forward-looking statements are subject to a number of risks and uncertainties, including but not limited to changes in domestic and foreign business, market, financial, political, and legal conditions; the inability of the parties to successfully or timely consummate the Business Combination and other related transactions, including the risk that any regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions (such as any SEC statements or enforcements or other actions relating to special purpose acquisition companies) that could adversely affect the combined company or the expected benefits of the Business Combination and other related transactions; failure to realize the anticipated benefits of the Business Combination and other related transactions; risks related to ThomasLloyd, including but not limited to (i) its ability to implement strategy and identify suitable sustainable investment opportunities, (ii) political developments, laws and regulations in areas where ThomasLloyd operates, (iii) increased competition in the industries where ThomasLloyd operates, (iv) supply of natural resources necessary for ThomasLloyd’s operations, (v) reliance on third-party supplier and service providers, (vi) the effects of climate change, extreme weather events, and seismic events, and (vii) fluctuations in currency markets. Additional risks related to Roman include those factors discussed in documents Roman has filed or will file with the SEC, together with the risks described in the document entitled “Risk Factors” that has been made available to interested parties concurrent with this Current Report on Form 8-K and also set forth in the section entitled “Risk Factors” and “Special Note Regarding Forward-Looking Statements” in Roman’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2025, Roman’s Annual Report on Form 10-K for the year ended December 31, 2024, and in those documents that Roman has filed, or will file, with the SEC.

If any of these risks materialize or Roman’s or ThomasLloyd’s assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that neither Roman nor ThomasLloyd presently know or that Roman and ThomasLloyd currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect Roman’s and ThomasLloyd’s expectations, plans, or forecasts of future events and views as of the date of this Current Report on Form 8-K and are qualified in their entirety by reference to the cautionary statements herein. Roman and ThomasLloyd anticipate that subsequent events and developments will cause Roman’s and ThomasLloyd’s assessments to change. These forward-looking statements should not be relied upon as representing Roman’s and ThomasLloyd’s assessments as of any date subsequent to the date of this Current Report on Form 8-K. Accordingly, undue reliance should not be placed upon the forward-looking statements. Neither Roman, ThomasLloyd nor any of their respective affiliates undertake any obligation to update these forward-looking statements, except as required by law.
