You have previously received definitive proxy materials dated January 20, 2026 (the "**<u>Proxy Statement</u><u>/</u><u>Prospectus</u>**") in connection with the Special Meeting of Trailblazer Merger Corporation I, a Delaware corporation ("**<u>Trailblazer</u>**," the "**<u>Company</u>**", "**<u>we</u>**", "**<u>us</u>**" or "**<u>our</u>**"), to be held on February 18, 2026 at 10:00 A.M., Eastern time, via virtual meeting format (the "**<u>Special Meeting</u>**").

The purpose of this document (the "**<u>Supplement</u>**") is to supplement the Proxy Statement/Prospectus with certain new and/or revised information as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. To report the resignation of the Company's Chief Executive Officer, Arie Rabinowitz, and the appointment of Yosef Eichorn as Chief Executive Officer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. To disclose the entry by Trailblazer Holdings, Inc. ("**<u>Holdings</u>**") into subscription agreements for an additional $2.0 million private investment in public equity ("**<u>PIPE</u>**") financing on substantially the same terms as the previously disclosed $6.0 million PIPE financing; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. To provide an updated internet link for attendance at the virtual meeting.

Except as specifically amended or supplemented by this Supplement, the disclosures contained in the Proxy Statement/Prospectus remain unchanged. This Supplement should be read in conjunction with the Proxy Statement/Prospectus.

#### RECENT DEVELOPMENTS

#### Resignation of Chief Executive Officer and Director; Appointment of Chief Executive Officer
On January 20, 2026, Arie Rabinowitz resigned as a director and the Chief Executive Officer of the Company. Mr. Rabinowitz's resignation was not the result of any disagreement between him and the Company, the Board of Directors of the Company (the "**<u>Board of Directors</u>**"), or any committee of the Board of Directors on any matter. On the same day, Mr. Rabinowitz also resigned as the Chief Executive Officer and sole director of Holdings.

#### Appointment of Chief Executive Officer
On January 21, 2026, the Board of Directors appointed Yosef Eichorn as the Company's Chief Executive Officer, and as the Chief Executive Officer and sole director of Holdings. Mr. Eichorn is also currently the Chief Development Officer of the Company.

Mr. Eichorn also serves as the Vice President of Investments at LHX Corp. Mr. Eichorn has served in this capacity since February 2025. Previously he served in the same capacity at LH Financial since January 2020. Mr. Eichorn focuses on evaluating new investment opportunities in addition to monitoring the family's active portfolio companies. From March 2019 to September 2021, Mr. Eichorn served as Compliance Officer at LH Financial. He was responsible for compliance, developing and updating LH Financial Services Corp. and its family client's compliance framework and procedures to ensure that LH Financial and its family client comply with applicable policies and regulations. From July 2018 to December 2019, Mr. Eichorn served as a Research Analyst at LH Financial. Mr. Eichorn is the son-in-law of Mr. Rabinowitz. Yosef Eichorn graduated from Empire State College with a BS in Liberal Arts.

#### Additional PIPE Financing
As previously disclosed, on December 18, 2025, Holdings entered into subscription agreements with certain investors providing for a $6.0 million PIPE investment in Holdings Series B preferred stock and warrants.

On February 5, 2026, subsequent to the filing of the Proxy Statement/Prospectus, Holdings entered into additional subscription agreements with certain investors providing for an additional $2.0 million private placement investment in Holdings Series B preferred stock and warrants (the "**<u>Additional PIPE Investment</u>**").

The Additional PIPE Investment was entered into on substantially the same terms as the previously disclosed $6.0 million PIPE financing. As a result of the Additional PIPE Investment, the total committed PIPE financing has been increased to $8.0 million.

All references to the "PIPE Investment" in Proposal 5 of the Proxy Statement/Prospectus shall be deemed to include the Additional PIPE Investment.
