Exhibit 99.1
Estrella Immunopharma Announces $1 Million Share

Emeryville, Jan 30, 2024 — Estrella Immunopharma, Inc. (NASDAQ:
ESLA, ESLAW ) (“Estrella Immunopharma” or “Estrella”), a clinical-stage biopharmaceutical company developing CD19
and CD22-targeted ARTEMIS® T-cell therapies with the capacity to address treatment challenges for patients with blood cancers and
solid tumors, is pleased to announce that its board of directors has authorized share repurchases of up to $1 million of its common stock.
“The share repurchase authorization underscores Estrella’s
commitment to driving shareholder value, as well as management’s confidence in Estrella’s value and long-term potential,”
said Dr. Cheng Liu, CEO and Chairman of Estrella.
“The share repurchase authorization reflects confidence in Estrella’s
strategic direction and continued development of our innovative therapies,” commented Peter Xu, CFO of Estrella.
The authorization does not constitute a formal or binding commitment

About Estrella Immunopharma
Estrella is a clinical-stage biopharmaceutical
company developing CD19 and CD22-targeted ARTEMIS® T-cell therapies with the capacity to address treatment challenges for patients
with blood cancers and solid tumors. Estrella’s mission is to harness the evolutionary power of the human immune system to transform the
lives of patients fighting cancer. To accomplish this mission, Estrella’s lead product candidate, EB103, utilizes Eureka’s ARTEMIS®
technology to target CD19, a protein expressed on the surface of almost all B-cell leukemias and lymphomas. Estrella is also developing
EB104, which also utilizes Eureka’s ARTEMIS® technology to target not only CD19, but also CD22, a protein that, like CD19, is expressed
on the surface of most B-cell malignancies. Estrella is also collaborating with Imugene Limited and its product candidate, CF33-CD19t
an oncolytic virus (“CF33-CD19t”), to research the use of EB103 in conjunction with CF33-CD19t to treat solid tumors using a
“mark and kill” strategy. For more information about Estrella Immunopharma, please visit estrellabio.com

Item 4.01 Changes in Registrant’s Certifying Accountant
(a) Dismissal of Independent Registered Public Accounting Firm
Estrella Immunopharma, Inc. (the “Company”),
at the direction of the Board of Directors of the Company (the “Board”), and upon the recommendation of the Audit Committee
of the Board, dismissed its independent registered public accountant Marcum LLP (“Marcum”), effective as of January 30, 2024.
Marcum was initially engaged on November 3, 2022 by Estrella Biopharma, Inc. (“Estrella”), the Company’s wholly-owned
subsidiary and accounting predecessor following the consummation of the business combination between Estrella, Tradeup Merger Sub Inc.
and TradeUP Acquisition Corp. on September 29, 2023, to serve as Estrella’s auditor for its fiscal year ended June 30, 2023.
Marcum’s report on Estrella’s financial
statements for the fiscal year ended June 30, 2023 did not contain an adverse opinion or a disclaimer of opinion, and was not qualified
or modified as to uncertainty, audit scope, or accounting principles, except that Marcum’s report contained an explanatory paragraph
expressing substantial doubt about the ability of Estrella to continue as a going concern.
During the fiscal year ended June 30, 2023 and
subsequent interim periods through the date of Marcum’s dismissal, there were (i) no disagreements with Marcum on any matter of
accounting principles or practices, financial statement disclosure, or auditing scope or procedure, any of which, if not resolved to Marcum’s
satisfaction, would have caused it to make reference to the subject matter of any such disagreement in connection with its reports for
such years and (ii) no “reportable events” requiring disclosure pursuant to paragraph (a)(1)(v) of Item 304 of Regulation
S-K and the related instructions to Item 304 of Regulation S-K.
In accordance with Item 304(a)(3) of Regulation
S-K, the Company has provided Marcum a copy of the disclosures it is making in this Current Report on Form 8-K prior to filing with the
Securities and Exchange Commission (the “SEC”) and requested that Marcum furnish the Company with a letter addressed to the
SEC stating whether or not Marcum agrees with the above statements. A copy of Marcum’s letter, dated February 1, 2024, is filed
as Exhibit 16.1 to this Current Report on Form 8-K.
(b) Appointment of New Independent Registered Public Accounting Firm
At the direction of the Board, and upon the recommendation
of the Audit Committee, the Company appointed Macias Gini & O’Connell, LLP (“MGO”) as the Company’s new independent
registered public accounting firm for the fiscal year ending June 30, 2024, effective as of January 30, 2024. During the Company’s
two most recent fiscal years ended June 30, 2022, and June 30, 2023, and the subsequent interim period through the date of MGO’s
engagement, neither the Company nor anyone on its behalf has consulted with MGO regarding (i) the application of accounting principles
to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial
statements, where either a written report or oral advice was provided to the Company that MGO concluded was an important factor considered
by the Company in reaching a decision as to the accounting, auditing or financial reporting issue, (ii) any matter that was the subject
of a disagreement within the meaning of Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K
or (iii) any reportable event within the meaning of Item 304(a)(1)(v) of Regulation S-K.
