The transactions contemplated by the Business Combination Agreement are referenced as the "Business Combination". A copy of the press release is attached to this Current Report on Form 8-K as Exhibit 99.1 and is incorporated herein by reference.

The press release shall not be deemed "filed" for any purpose, including for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act") or otherwise subject to the liabilities of that Section. The information in this Item 7.01, including Exhibit 99.1, shall not be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended (the "Securities Act"), or the Exchange Act regardless of any general incorporation language in the filing.

**Forward-Looking Statements**

This Current Report on Form 8-K contains certain statements that are not historical facts and are forward-looking statements within the meaning of the federal securities laws with respect to the Business Combination, including without limitation statements regarding the expectations regarding the timing and completion of the proposed business combination, the anticipated listing on Nasdaq, the expected proceeds and use of capital, the timing and results of clinical trials, anticipated regulatory submissions and approvals, the commercial potential of product candidates, and statements regarding the capabilities and potential of PrimeGen US's technology platform. These forward-looking statements generally are identified by the words "believe," "project," "expect," "anticipate," "estimate," "intend," "think," "strategy," "future," "opportunity," "potential," "plan," "seeks," "may," "should," "will," "would," "will be," "will continue," "will likely result," and similar expressions, but the absence of these words does not mean that a statement is not forward-looking. Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties.

These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on 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 will differ from assumptions. Many factors could cause actual future events to differ materially from the forward-looking statements in this communication, including but not limited to: (i) the risk that the Business Combination may not be completed in a timely manner or at all, which may adversely affect the price of DTCS's securities; (ii) the risk that the Business Combination may not be completed by DTCS's business combination deadline and the potential failure to obtain an extension of the business combination deadline if sought by DTCS; (iii) the failure to satisfy the conditions to the consummation of the Business Combination, including the approval of the Business Combination Agreement by the shareholders of DTCS, the satisfaction of the closing requirements and the receipt of certain governmental, regulatory and third party approvals; (iv) the occurrence of any event, change or other circumstance that could give rise to the termination of the Business Combination Agreement; (v) redemptions exceeding anticipated levels; (vi) the failure to meet Nasdaq initial listing standards in connection with the consummation of the Business Combination; (vii) the effect of the announcement or pendency of the Business Combination on the Company's business relationships, operating results, and business generally; (viii) risks that the Business Combination disrupts current plans and operations of the Company; (ix) the outcome of any legal proceedings that may be instituted against Parent Parties and the Company related to the Business Combination Agreement or the Business Combination; (x) the inherent uncertainty of clinical success and the risk that trials may be delayed or fail to meet primary endpoints; (xi) changes in domestic and global general economic conditions; (xii) the possibility that FDA or other regulatory authorities may not approve candidates or may require additional data; (xiii) compliance with emerging regulations, including the BIOSECURE Act, and other applicable regulations and their impact on manufacturing and supply chain partnerships; (xiv) the risk that Parent may not be able to develop and maintain effective internal controls; (xv) costs related to the Business Combination and the failure to realize anticipated benefits of the Business Combination or to realize estimated pro forma results and underlying assumptions, including with respect to estimated shareholder redemptions; (xvi) the ability to recognize the anticipated benefits of the Business Combination and to achieve commercialization and development plans, and identify and realize additional opportunities, which may be affected by, among other things, competition, the ability of the Company to grow and manage growth economically and hire and retain key employees; (xvii) inability to achieve successful results or to obtain licensing of third-party intellectual property rights for future discovery and development of the Company's projects; (xviii) failure to commercialize products and achieve market acceptance of such products; (xix) the risk that the Company will need to raise additional capital to execute its business plan, which may not be available on acceptable terms or at all; (xx) the risk of product liability or regulatory lawsuits or proceedings relating to the Company's business; (xxi) risks associated with intellectual property protection; (xxii) the risk that the Company is unable to secure or protect its intellectual property and (xxiii) those factors discussed in documents of DTCS and Parent filed or to be filed with the SEC, including in the registration statement relating to the Business Combination (the "Registration Statement").

The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties that will be described in the "Risk Factors" section of the Registration Statement and the amendments thereto, and other documents to be filed by DTCS and Purchaser from time to time with the SEC. These filings 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. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and while Purchaser and DTCS may elect to update these forward-looking statements at some point in the future, they assume no obligation to update or revise these forward-looking statements, whether as a result of new information, future events or otherwise, except as required by applicable law. None of DTCS or the Company gives any assurance that DTCS or the Company will achieve expectations. These forward-looking statements should not be relied upon as representing Company's or DTCS's assessments as of any date subsequent to the date of this Current Report. Accordingly, undue reliance should not be placed upon any forward-looking statements.

**Additional Information About the Business Combination and Where to Find It**

## Exhibit 99.1

**Exhibit 99.1**

**PrimeGen US, Inc. Announces Proposed Business Combination with DT Cloud Star Acquisition Corporation at an Implied Equity Value of Approximately $1.5 Billion to Advance Its Stem Cell Research and Development Efforts**

SANTA ANA, CALIFORNIA, February 4, 2026 – PrimeGen US, Inc. ("PrimeGen US" or the "Company"), a pioneering biotech company advancing innovative stem cell and exosome therapies, today announced it has entered into a definitive business combination agreement dated as of February 2, 2026 (the "Business Combination Agreement") with DT Cloud Star Acquisition Corporation ("DT Cloud Star"), a publicly traded special purpose acquisition company (Nasdaq: DTSQ). The transaction implies an equity value for PrimeGen US of approximately $1.5 billion and is expected to provide access to the public markets capital, which the combined company intends to use to advance clinical development, regulatory activities, and if approved, potential commercialization of its lead programs.

Upon closing, which is subject to approval by the stockholders of both PrimeGen US and DT Cloud Star, receipt of required regulatory approvals (including compliance with the Hart-Scott-Rodino Antitrust Improvements Act, if applicable), satisfaction of minimum cash conditions (including any applicable minimum cash condition and redemption thresholds), and other customary closing conditions set forth in the Business Combination Agreement, the combined company is expected to operate as PrimeGen US (or a successor entity) and is anticipated to list on the Nasdaq, subject to Nasdaq approval, under a new ticker symbol. The transaction is currently expected to close in the second half of 2026, although there can be no assurance regarding the timing or completion of the transaction.

"We are thrilled to partner with DT Cloud Star to bring PrimeGen US into the public markets at this pivotal moment," said Daniel Chiu, Co-CEO and Chairman of PrimeGen US. "This transaction is expected to enhance our access to capital and resources, supporting the continued development of our stem cell and exosome programs. Our team's scientific focus and innovation position us to further build our presence in the regenerative medicine field."

PrimeGen US is a regenerative medicine company, leveraging nearly two decades of proprietary stem cell research to develop Triple Activated Mesenchymal Stem Cells (MSCs) as a novel, cell-based treatment for acute liver injury and related critical conditions. The Company's platform has demonstrated in preclinical activity in animal studies, and recent advancements include completion of a Pre-Investigational New Drug application (Pre-IND) meeting for Acute Alcoholic Hepatitis (Acute Liver Failure) with the U.S. Food & Drug Administration (FDA) on December 17, 2025. There can be no assurance that the FDA will allow an IND to proceed or that any clinical trials will be successful, and preclinical results may not be indicative of clinical outcomes in humans. PrimeGen US is working toward the initiation of a clinical trial, subject to regulatory approval, to support further development of Triple Activated MSCs for the potential treatment of Acute Alcoholic Hepatitis (Acute Liver Failure).

Wai Szeto, Co-CEO of PrimeGen US, added: "With nearly two decades of foundational stem cell technology as our launchpad, we have developed our Triple Activated MSC platform into a differentiated platform under development that we believe is well positioned to advance through its next stages of development, subject to regulatory review."

Sam Zheng Sun, Chairman and CEO of DT Cloud Star Acquisition Corporation, commented: "We are pleased to partner with PrimeGen US in this business combination. We have great confidence that under the leadership of Co-CEOs Daniel Chiu and Wai Szeto, the company is uniquely positioned to deliver much-needed regenerative medicine to treat challenging diseases, such as acute liver failure. By leveraging PrimeGen's nearly two decades of research and their Triple Activated MSC platform, we believe the combined entity will successfully capture large unmet market opportunities and provide significant value to patients and shareholders alike."

Before making any voting decision, securities holders of DT Cloud Star are urged to read the proxy statement/prospectus, when available, and all other relevant documents filed or that will be filed with the SEC in connection with the proposed business combination as they become available, because they will contain important information about the proposed business combination and the parties to the proposed business combination.

**Participants In The Solicitation**

Information about DT Cloud Star's directors and executive officers and their ownership of DT Cloud Star's securities is set forth in DT Cloud Star filings with the SEC, including DT Cloud Star's Annual Report on Form 10-K for the fiscal year ended December 31, 2024, which was filed with the SEC on March 31, 2025. To the extent that holdings of DT Cloud Star's securities have changed since the amounts set forth in DT Cloud Star's Annual Report, such changes have been or will be reflected on Statements of Change in Ownership on Form 4 filed with the SEC.

Additional information regarding the participants in the proxy solicitation and a description of their direct and indirect interests will be included in the Registration Statement and its proxy statement/prospectus when it becomes available. Shareholders, potential investors, and other interested persons in respect of PrimeGen US, Pubco and DT Cloud Star should read the Registration Statement, proxy statement/prospectus carefully when it becomes available before making any voting or investment decisions. You may obtain free copies of these documents from the sources indicated above.

**Safe Harbor Statement: Forward-Looking Statements**

This press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements generally relate to future events and include, but are not limited to, projections, forecasts, and estimates about possible or assumed future results of the business combination, and PrimeGen US's business, financial condition, results of operations, liquidity, plans and objectives. These statements include, but are not limited to, expectations regarding the timing and completion of the proposed business combination, the anticipated listing on Nasdaq, the expected proceeds and use of capital, the timing and results of clinical trials, anticipated regulatory submissions and approvals, the commercial potential of product candidates, and statements regarding the capabilities and potential of PrimeGen US's technology platform. You can generally identify forward-looking statements by the use of words such as "believe," "may," "will," "estimate," "continue," "anticipate," "intend," "expect," "should," "would," "plan," "project," "forecast," "predict," "potential," "seem," "seek," "future," "outlook," "target" or other similar expressions that predict, indicate or relate to future events or trends or PrimeGen US's or DT Cloud Star's future financial or operating performance, or that are not statements of historical matters. Forward-looking statements are subject to significant risks and uncertainties that could cause actual results to differ materially from expected results. Most of these factors are outside of PrimeGen US's and DT Cloud Star's control and are difficult to predict. Factors that may cause such differences include, but are not limited to:

● The inherent uncertainty of clinical success and the risk that trials may be delayed or fail to meet primary endpoints.

● The possibility that FDA or other regulatory authorities may not approve candidates or may require additional data.

● Compliance with emerging regulations, including the BIOSECURE Act, and other applicable regulations and their impact on manufacturing and supply chain partnerships.

● The ability to obtain and maintain intellectual property protection.

● The availability of funding to support continued research and development.

Additional risks and uncertainties that could cause actual results to differ from those expressed in any forward-looking statements are described in greater detail in DT Cloud Star's filings with the SEC, including its Annual Report on Form 10-K and Quarterly Reports on Form 10-Q, and will be described in the registration statement on Form S-4 (or Form F-4), proxy statement/prospectus and other documents filed with the SEC in connection with the proposed business combination. Neither PrimeGen US nor DT Cloud Star undertakes any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws.
