AI summary

HCLTech responded to media reports about a hacker group claiming exposure of limited employee data. Initial investigation suggests the data is limited and from a few years back. No evidence was found of a breach to company systems or any client engagement. Further investigation is underway, and material findings will be reported. The company stressed that cybersecurity is a top priority.

Likely market impact

Limited near-term impact expected since no current breach confirmed, but ongoing probe and headlines may keep the stock under mild watch.
