Exhibit 99.1

TDAC Announces ProLogium’s Filing of F-4 As Continuing Momentum

Towards Merger

NEW YORK, NY – July 6, 2026 –

Translational Development Acquisition Company (NYSE: TDAC) ( “TDAC”) announced that ProLogium has filed their initial

F-4 with the SEC driving the companies forward towards a successful execution of the de-SPAC transaction. This filing gives the SEC

and investors at large a fuller view into the history of ProLogium and further supporting information into the merger transaction

that was announced on May 27, 2026.

Michael Hoffman, Chairman and CEO of TDAC, commented, “We

continue to be tremendously excited to work with the ProLogium team on this transaction. We believe that this F-4 filing with the SEC

will provide investors significant color into the company and the transaction and would be a tremendously helpful resource.”

Please note that this filing is subject to SEC Review and may be revised.

For further information please see ProLogium’s website at www.prologium.com and to access the filings please visit the SEC

website at www.sec.gov.

Forward-Looking Statements

This communication contains forward-looking statements within the meaning

of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Exchange Act of 1934, as amended 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 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 communication or elsewhere 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 communication 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 (including the $250 million Minimum Cash condition); failure to obtain TDAC deadline extension; the amount of redemption

requests made by TDAC’s public 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 execute on its business strategy and the ability to develop

and commercialize its solid-state battery technology; the ability to accurately estimate the future supply and demand for its batteries;

the ability to respond rapidly to emerging technology trends; the ability to compete effectively and the ability to manage growth; 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 communication represent the views of ProLogium and TDAC as of the date of this communication. 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 communication after the date of this communication.

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 communication.
