SUPPLEMENT TO

PROXY STATEMENT DATED SEPTEMBER 6, 2024

FOR ANNUAL MEETING

OF

TRAILBLAZER MERGER CORPORATION I

Dear Stockholders of Trailblazer Merger Corporation I:

You have previously received definitive proxy materials dated September 6, 2024 (the “Proxy Statement”) in connection with the annual meeting of Trailblazer Merger Corporation I, a Delaware corporation (the “company”, “we”, “us” or “our”), which was scheduled to be held on September 24, 2024 at 10:00 A.M., Eastern time, (the “annual meeting”), or at such other time, on such other date and at such other place to which the meeting may be postponed or adjourned, and will be available to attend via teleconference.

The Meeting was duly held on September 24, 2024 at 10:00 A.M. Eastern Time wherein the only proposal to be voted on by stockholders of the company was a proposal to adjourn the annual meeting to September 26, 2024 at 10:00 A.M., Eastern time, or at such other time, on such other date and at such other place to which the meeting may be postponed or adjourned (the “adjourned meeting”). That proposal was approved by the requisite number of stockholders.

The purpose of this proxy supplement (the “Proxy Supplement”) is to supplement the Proxy Statement with certain new and/or revised information relating to the adjourned meeting as set forth below. Capitalized terms used herein but not defined herein have the meanings ascribed thereto in the Proxy Statement.

Change in Terms for Extension. Proposal 1 of the Proxy Statement originally provided that if the Extension Amendment Proposal is approved and the Charter Extension becomes effective, within five business days of the date of the Annual Meeting, the Sponsor) (or one or more of its affiliates, members or third-party designees) (the “Lender”) shall make an initial deposit into the Trust Account in an amount equal to the lesser of (i) $0.015 for each outstanding share of Public Stock after giving effect to the Redemption , and (ii) $100,000, in exchange for a non-interest bearing, unsecured promissory note issued by the Company to the Lender. The initial deposit will extend the deadline for completing the Business Combination to October 30, 2024. For each subsequent monthly extension approved by the Board after September 30, 2024, an additional deposit equal to the initial deposit will further extend the deadline by one month, up to the Charter Extension Date.

This Proxy Supplement changes the amount to be deposited into the Trust Account each month to an amount equal to $0.035 multiplied by the number of public shares of the Company that are not redeemed in connection with the Meeting as set forth in Annex B.

Elimination of Amount Withdrawn from Trust to Pay Dissolution Expenses. Proposal No. 2 of the Proxy Statement proposes to amend the Company’s Trust Agreement, allowing the Company to extend the date by which the Company must consummate a business combination up to twelve (12) times, each such extension for an additional one (1) month period, until September 30, 2025. This Proxy Supplement also proposes to amend the Trust Agreement and the Certificate of Incorporation in order to remove the provisions that permit the Trustee to release from the Trust Account up to $100,000 of interest for Company dissolution expenses as set forth in Annex A and Annex B.

No Payment of Excise Taxes from Trust Account. This Proxy Supplement hereby clarifies that the Company will not be permitted to use any proceeds placed in the Trust Account or the interest earned thereon to pay any excise taxes or any other similar fees imposed under the Inflation Reduction Act (IRA) of 2022 (H.R. 5376) in connection with any redemptions or stock buybacks by the Company.

Payment of Other Taxes Prior to Distributions from the Trust Account. As previously disclosed in the Proxy Statement, on September 4, 2024, the most recent practicable date prior to the date of the Proxy Statement, the redemption price per share was approximately $11.08 (which is expected to be the same approximate amount two business days prior to the annual meeting), based on the aggregate amount on deposit in the Trust Account of approximately $76,454,620.11 as of September 4, 2024 (including interest not previously released to the Company to pay its franchise and income taxes), divided by the total number of then outstanding shares of the Company’s publicly held stock. With respect thereto, and in accordance with the terms of the Trust Agreement, the Company advises its stockholders that prior to making any redemption distributions from the Trust Account related to the annual meeting, the Company intends to withdraw interest from the Trust Account in order to pay its income and franchise taxes through September 20, 2024 in their entirety as estimated below.

Adjournment of Annual Meeting. Due to the changes described above, the company has decided to adjourn annual meeting. The adjourned meeting will take place on September 26, 2024 10:00 A.M. Eastern time. The meeting will be accessible via teleconference at:
