They said that the call has been shifted to Tuesday, August 29, as he is apparently unwell.
The conference call had been organised by broker Investec India, and large global investors were expected to tune-in to the call to listen to Murthy who has taken on the Infosys Board alleging lapses in corporate governance and other issues.
This will be Murthy's first address to investors after Sikka suddenly resigned last week, and institutional investors would be watching out for cues on the company's future course.
Last Friday, the first non-founder CEO of Infosys, Vishal Sikka had cited "malicious" and "personal attacks" while resigning from the company following months of acrimony with high-profile founders, led by Murthy. While Sikka did not name Murthy for his exit, the Board of the $10 billion firm blamed the founder for "continuous assault" through "factually inaccurate" and "already-disproved rumours" for the resignation of the CEO.
Murthy, however, maintained that his only concerns are the lapses in corporate governance standards for which Infosys was admired for at one point.
Troubles mounted for Infosys when an anonymous letter was sent to the market regulators in February this year, alleging that the company's acquisition of Panaya was overvalued and that some Infosys executives may have benefited from the deal.
While an independent probe absolved the board of any wrong doing, Murthy kept insisting that the company should go public with the full contents of the investigation report. Infosys has so far refused to make it public.
