The acquisition was disclosed to the National Stock Exchange of India Limited and BSE Limited on August 1, 2026, pursuant to Regulation 29(2) of the SEBI (Substantial Acquisition of Shares and Takeovers) Regulations, 2011.

| Holding Category | Before Acquisition (Shares) | % of Voting Capital | After Acquisition (Shares) | % of Voting Capital |
|---|---|---|---|---|
| Equity Shares | 34,63,473 | 5.17% | 49,10,768 | 7.33% |

The total paid-up equity share capital of Updater Services Limited remains unchanged at 6,69,53,241 equity shares of ₹10 each. However, the total diluted share/voting capital stands at 6,80,45,783 equity shares, assuming full conversion of outstanding stock options. Consequently, SIS Limited’s stake in terms of diluted voting capital now stands at 7.22%, up from 5.09% previously. The acquirer does not belong to the promoter or promoter group of the target company, classifying it as a non-promoter investor.
What the Numbers Show
The incremental increase of 2.16% in a single open market transaction suggests a deliberate accumulation strategy by SIS Limited. With the holding crossing the 7% threshold, SIS Limited remains below the 10% substantial acquisition trigger that would mandate an open offer under typical takeover regulations, though continued monitoring of further purchases is warranted. The absence of pledged shares indicates that the acquired securities are free from encumbrances, providing clear title and voting rights to the acquirer.
