I cannot directly access external web links or PDF documents like the `Investor-Presentation-Q4-FY-2025-26.pdf` mentioned in the provided text.

The text you've provided is a cover letter announcing the availability of the investor presentation, not the presentation itself.

To create the summary you've requested, please provide the actual content of the "Investors Presentation on the Audited Financial Results for the quarter and year ended March 31, 2026." Once you provide the content, I will apply all your preferences and create the summary.
