Results

of Operations and Financial Condition.

Tonix

Pharmaceuticals Holding Corp. (the “Company”) is disclosing selected preliminary operating results for the quarter ended

September 30, 2026.

For

the three months ended September 30, 2026, the Company’s net revenue for TONMYA is estimated to be between $14.0 million and $15.0

million.

of September 30, 2026, the Company estimates that its cash and cash equivalents were approximately $162.8 million.

The

above information is preliminary financial information for the quarter ended September 30, 2026, and subject to completion. The unaudited,

estimated results for the quarter ended September 30, 2026, are preliminary and were prepared by the Company’s management, based

upon its estimates, a number of assumptions and currently available information, and are subject to revision based upon, among other

things, quarter-end closing procedures and/or adjustments, the completion of the Company’s consolidated financial statements and

other operational procedures. This preliminary financial information is the responsibility of management and has been prepared in good

faith on a consistent basis with prior periods. However, the Company has not completed its financial closing procedures for the quarter

ended September 30, 2026, and its actual results could be materially different from this preliminary financial information, which preliminary

information should not be regarded as a representation by the Company or its management as to its actual results for the quarter ended

September 30, 2026. During the course of the preparation

of the Company’s financial statements and related notes as of and for the quarter ended September 30, 2026, the Company may identify

items that would require it to make material adjustments to this preliminary financial information. As a result, prospective investors

should exercise caution in relying on this information and should not draw any inferences from this information. This preliminary financial

information should not be viewed as a substitute for full financial statements prepared in accordance with United States generally accepted

accounting principles and reviewed by the Company’s auditors.

The

information included in Item 2.02 is incorporated herein by reference.
