The information in this Item 7.01, including Exhibits 99.1 and 99.2, is being furnished pursuant to Item 7.01 and will not be deemed to be filed for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise be subject to the liabilities of that section, nor will it be deemed to be incorporated by reference in any filing under the Securities Act or the Exchange Act, regardless of any general incorporation language in such filings.

Forward-Looking Statements

This Current Report contains forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act that are based on beliefs and assumptions and on information currently available to ProLogium and TDAC. In some cases, you can identify forward-looking statements by the following words: “may,” “will,” “could,” “would,” “should,” “expect,” “intend,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “project,” “potential,” “continue,” “ongoing,” “target,” “seek” or the negative or plural of these words, or other similar expressions that are predictions or indicate future events or prospects, although not all forward-looking statements contain these words. Any statements that refer to expectations, projections or other characterizations of future events or circumstances, including projections of market opportunity, number of customers, vendors or users and market share, the capability of ProLogium’s technology, ProLogium’s business plans including its plans to expand globally, the sources and uses of proceeds from the Business Combination, the anticipated enterprise value of the combined company following the consummation of the Business Combination, any benefits of ProLogium’s partnerships, strategies or plans as they relate to the Business Combination, anticipated benefits of the Business Combination and expectations related to the terms and timing of the Business Combination are also forward-looking statements.

These statements involve risks, uncertainties and other factors that may cause actual results, levels of activity, performance or achievements to be materially different from those expressed or implied by these forward-looking statements. These statements are based on ProLogium’s and TDAC’s reasonable expectations and beliefs concerning future events and involve risks and uncertainties that may cause actual results to differ materially from current expectations. These factors are difficult to predict accurately and may be beyond ProLogium’s and TDAC’s control. Forward-looking statements in this Current Report speak only as of the date made. New uncertainties and risks arise from time to time, and it is impossible for ProLogium or TDAC to predict these events or how they may affect ProLogium or TDAC. In addition, there will be risks and uncertainties described in the proxy statement/prospectus relating to the Business Combination, which is expected to be filed by ProLogium with the SEC, and other documents filed by ProLogium or TDAC from time to time with the SEC. These filings may identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements.

Neither ProLogium nor TDAC can assure you that the forward-looking statements in this Current Report will prove to be accurate. These forward-looking statements are subject to a number of risks and uncertainties, including, among others, the occurrence of any event, change or other circumstance that could delay, impede or prevent the Business Combination or give rise to the termination of the Business Combination Agreement; the outcome of any legal proceedings that may be instituted against ProLogium or TDAC, the combined company or others following the announcement of the Business Combination; the inability to complete the Business Combination due to the failure to obtain approval of the shareholders of ProLogium or TDAC or to satisfy other conditions to closing; failure to obtain the TDAC Extension, the amount of redemption requests made by TDAC’s public shareholders or the Company Shareholders; the ability to maintain the stock exchange listing standards following the consummation of the Business Combination; the risk that the Business Combination disrupts current plans and operations of ProLogium or TDAC as a result of the announcement and consummation of the Business Combination; the ability to recognize the anticipated benefits of the Business Combination; costs related to the Business Combination; changes in applicable laws or regulations; international trade disputes, including threatened or implemented tariffs by the U.S. and threatened or implemented tariffs by foreign countries in retaliation; the ability of ProLogium to execute its business model, including market acceptance of its planned products and services; the combined company’s ability to raise capital; future financial performance of the combined company following the Business Combination; the possibility that TDAC or the combined company may be adversely affected by other economic, business and/or competitive factors; risks associated with ProLogium’s efforts to commercialize its products; ProLogium’s ability to maintain its existing agreements with third parties and to negotiate and enter into new definitive agreements on favorable terms, if at all; the impact of competing products on ProLogium’s business; intellectual property-related claims against ProLogium or the combined company; ProLogium’s dependence upon its key personnel and ability to attract and retain such personnel and additional qualified personnel; ProLogium’s ability to source raw materials for its products; and other risks and uncertainties to be set forth in the section entitled “Risk Factors” in the registration statement on Form F-4 to be filed by ProLogium with the SEC and those included under the heading “Risk Factors” in TDAC’s filings with the SEC. There may be additional risks that neither ProLogium nor TDAC presently knows or that ProLogium and TDAC currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements.

In light of the significant uncertainties in these forward-looking statements, you should not regard these statements as a representation or warranty by ProLogium, TDAC, their respective directors, officers or employees or any other person that ProLogium or TDAC will achieve their objectives and plans in any specified time frame, or at all. The forward-looking statements in this Current Report represent the views of ProLogium and TDAC as of the date of this Current Report. Subsequent events and developments may cause those views to change. Except as required by applicable law, neither ProLogium nor TDAC has any duty to, and does not intend to, update or revise the forward-looking statements in this Current Report after the date of this Current Report. You should, therefore, not rely on these forward-looking statements as representing the views of ProLogium or TDAC as of any date subsequent to the date of this Current Report.

Additional Information and Where to Find It

In connection with the Business Combination, ProLogium is expected to file with the SEC a registration statement on Form F-4, which will include a proxy statement of TDAC and a prospectus of ProLogium. TDAC shareholders and other interested persons are encouraged to read, when available, the preliminary proxy statement/prospectus included in the registration statement and any other documents filed with the SEC because these documents will contain important information about ProLogium, TDAC and the Business Combination. After the registration statement is declared effective, the definitive proxy statement/prospectus to be included in the registration statement will be mailed to shareholders of TDAC as of a record date to be established for voting on the Business Combination. Before making any voting or investment decision, investors and shareholders of TDAC are urged to carefully read the entire registration statement and proxy statement/prospectus, when they become available, and any other relevant documents filed with the SEC, as well as any amendments or supplements to these documents, because they will contain important information about the Business Combination. The documents filed by TDAC and ProLogium with the SEC may be obtained free of charge at the SEC’s website at www.sec.gov.
