MET is incurred and paid by the mining entities.

In accordance with the previously updated MET methodology (effective 1 January 2023) the tax base for MET on uranium is determined as the weighted average price of uranium (in the form of natural uranium concentrate U₃O₈) from public price reporting sources for the corresponding reporting period, multiplied by the amount of uranium mined and a MET rate of 6%.

2025

Starting 1 January 2025 the applicable MET rate for uranium will change to 9% (only for the year 2025).

2026 and beyond

Starting 1 January 2026 a differentiated MET approach depending on the actual volume of annual production under each subsoil use agreement and the price of natural uranium concentrate (U₃O₈) will be introduced:

Furthermore, if the natural uranium concentrate (U₃O₈) price exceeds the values specified in the table below, an additional MET rate increase will be applicable:

As a result of the abovementioned changes, different JVs and subsidiaries of the Company are expected to have different applicable MET rates starting from 2026 and beyond.

The full text of the legislative act is available in Kazakh and Russian at the following link: https://online.zakon.kz/Document/?doc_id=35556206&doc_id2=32975511.

The amendments come into force beginning 1 January 2025 and it does not impact 2024 guidance or the Company's expectations related to taxation in 2024.
