ABOUT
THIS PROSPECTUS</div>

This prospectus is part of a registration statement on Form S-1 that
we have filed with the SEC for the delayed or continuous offering and sale of securities pursuant to Rule 415 under the Securities Act.
This prospectus generally describes OSR Holdings, Inc. and our common stock. The Selling Stockholder may use this registration statement
to sell up to an aggregate of up to 15,410,000 shares of our common stock from time to time through any means described in the section
entitled “Plan of Distribution.” Our registration of the securities covered by this prospectus does not mean that either we
or the Selling Stockholder will issue, offer or sell, as applicable, any of the securities registered hereunder. Under this registration
statement, the Selling Stockholder may, from time to time, sell the securities offered by it described in this prospectus.

We will not receive any proceeds from the sale
of common stock by the Selling Stockholder pursuant to this prospectus. However, we will pay the expenses, other than underwriting discounts
and commissions, associated with the sale of shares pursuant to this prospectus. We may receive up to $78.9 million in aggregate gross
proceeds from White Lion under the ELOC Agreement in connection with sales of the shares of our common stock pursuant to the ELOC Agreement
after the date of this prospectus, together with up to an additional $5,000,000 under the Warrant Agreement and Convertible Note Agreement.
However, the actual proceeds from White Lion may be less than this amount depending on the number of shares of our common stock sold
and the price at which the shares of our common stock are sold.

We and the Selling Stockholder, as applicable,
may deliver a prospectus supplement with this prospectus, to the extent appropriate, to update the information contained in this prospectus.
The prospectus supplement may also add, update or change information included in this prospectus. You should read both this prospectus,
any documents incorporated by reference to this prospectus, any post-effective amendment and any applicable prospectus supplement, together
with additional information described below under the captions “Incorporation of Documents by Reference” and “Where
You Can Find More Information.”

No offer of these securities will be made by
the Selling Stockholder in any jurisdiction where the offer is not permitted. You should rely only on the information contained in this
prospectus as may
