Corporate Securities Counsel

Routine withdrawal to revert to prior registration path.

"Pursuant to Rule 477(a) under the Securities Act of 1933"

Form F-3 regulatory

"Registration Statement on Form F-3 (File No. 333-295846)"

Form F-3 is a U.S. securities filing that lets eligible foreign companies pre-register and then quickly sell shares or other securities to raise money, because they already meet ongoing reporting and size tests. For investors it signals that the company is up-to-date with regulatory disclosure and has an efficient way to issue new securities — similar to a pre-approved credit line — which can mean faster capital raises but also potential dilution of existing holdings.

post-effective amendment regulatory

"instead intends to proceed by post-effective amendment to its existing registration statement"

A post-effective amendment is an official update to a securities registration document filed after that document has become effective with regulators; it corrects, adds or replaces information about the securities, the company, or an offering. Investors care because it keeps the legal record current and can change what is being sold or the rights attached to shares — like getting a revised product manual after a launch that may affect value or use.

Re: Trinity Biotech plc

Request for Withdrawal of Registration Statement on Form F-3

File No. 333-295846

Dear Ms. Hamill and Mr. Edwards:

Pursuant to Rule 477(a) under the Securities Act of 1933, as amended, Trinity Biotech plc (the “Company”) hereby respectfully requests that the Securities and Exchange Commission (the “Commission”) consent to the withdrawal of the Company’s Registration Statement on Form F-3, together with all exhibits thereto, filed with the Commission on May 13, 2026 (File No. 333-295846) (the “Registration Statement”).

As described in the explanatory note to the Registration Statement, the Registration Statement was filed to convert the Company’s existing effective Registration Statement on Form F-1 (File No. 333-293717), which was declared effective on March 3, 2026, into a Registration Statement on Form F-3 pursuant to Rule 429 under the Securities Act. The Company is seeking withdrawal of the Registration Statement because it has determined not to proceed with the resale offering on Form F-3 and instead intends to proceed by post-effective amendment to its existing registration statement on Form F-1.

The Registration Statement has not been declared effective by the Commission, and no securities have been issued or sold under the Registration Statement.

The Company submits that withdrawal of the Registration Statement is consistent with the public interest and the protection of investors, as contemplated by Rule 477(a). The Company requests that the Commission consent to the withdrawal of the Registration Statement effective as of the date hereof or at the earliest practicable date. It is our understanding that this application for withdrawal will be deemed granted as of the date it is filed with the Commission unless, within fifteen calendar days after such date, the Company receives notice from the Commission that this application will not be granted.

If you have any questions or comments regarding this request, please contact Mary Brown of Carter Ledyard & Milburn LLP at (212) 238-8765.

Very truly yours,

Trinity Biotech plc
