Attention:

The attached report is not submitted pursuant to the Securities Law. The report is submitted voluntarily by the corporation as part of its participation in a process promoted by the Israel Securities Authority for the implementation of iXBRL reporting in Israel, within which the corporation experiments with reporting in iXBRL format alongside the regular report.

The attached reports are based on the corporation's reports that were published on 18/05/2026 reference number 2026-01-045412. To these reports additional information was added regarding the tagging of certain data from the periodic and/or quarterly reports as instructed by the Authority, or tagging that the corporation chose to add at its own discretion. It is emphasized that the selection of such data does not constitute, in any way, an expression of opinion regarding their materiality in relation to other data in the periodic or quarterly reports for which tagging was not requested. The Israel Securities Authority or the corporation bear no responsibility of any kind for the content, reliability, accuracy or completeness of such tags, and the sole responsibility for their use lies with the user only.

The method of reporting and presentation provided herein (originating from the iXBRL format) may differ from the method of reporting and presentation as provided in the periodic and/or quarterly reports submitted by the reporting corporation (originating from a PDF format which differs from the iXBRL format).

In any case of discrepancy between the information provided herein and the information in the periodic or quarterly reports submitted by the reporting corporation (in the reporting form on MAGNA T930), the binding data are those presented in the periodic or quarterly reports.
