SIS Buyback Completed: ₹105.99 Crore Spent on 25 Lakh Shares, Post-Buyback Ad Filed October 20, 2026

The SIS buyback is finished, and it used every rupee it was allowed to. In a filing with NSE and BSE on October 20, 2026, the security services company said it had bought back 25,02,674 of its own shares from the open market and published the post-buyback public advertisement the same day. The programme ran from August 13 to October 16, 2026, and SIS spent ₹105.99 crore against a ceiling of ₹106 crore, which is 100% of the approved size, excluding transaction costs.

What the SIS buyback filing says

The closure intimation dated October 16 sets out the frame. The board approved the plan on August 5, 2026, capping the buyback at ₹106 crore and the price at ₹478.50 a share. Promoters, the promoter group and persons in control were kept out, so every share came from public holders, bought through the normal order book on both exchanges.

The October 20 filing, which carries the newspaper advertisement, fills in the detail:

• Shares bought back: 25,02,674, at a volume-weighted average price of ₹423.55.
• Highest price paid was ₹436.11 and the lowest ₹391.91. Neither came close to the ₹478.50 cap; the average sits about 11.5% below it (our calculation).
• The ₹105.99 crore works out to 9.99% of paid-up equity capital and free reserves on a standalone basis and 4.60% on a consolidated basis, as the filing states.
• 21,74,134 shares had already been extinguished for purchases up to September 30. The remaining 3,28,540, bought between October 1 and October 16, are to be extinguished by October 29, 2026.

Smaller share count, bigger promoter slice

The more lasting effect is on the shareholding pattern. As of July 31, 2026, SIS had 14,13,07,643 shares outstanding. After the buyback, and after 44,273 shares allotted under its employee stock option plan, the filing puts the post-buyback count at 13,88,49,242. Paid-up capital falls from ₹70.65 crore to ₹69.42 crore.

Promoters didn’t sell, so their 10,15,45,402 shares now make up a larger share of a smaller company: 73.13% after the buyback, up from 71.86%. Non-promoter holders together go from 28.14% to 26.87%. The shares bought back are roughly 1.77% of the pre-buyback count, by our working from the filing’s own numbers.

One quirk of the open-market route is worth knowing. Because purchases went through the exchanges, SIS says it can’t tell who sold, including whether any single holder sold more than 1% of the shares bought back. That is different from a tender-offer buyback, where shareholders apply directly. We explained a related route in our piece on open offers in the share market.

What it means for shareholders

For holders who stayed put, the maths is simple. Same business, fewer shares, so each remaining share owns a slightly larger piece of future profit. Earnings per share gets a small mechanical lift once the full extinguishment is done, though at under 2% of the equity, the effect is modest.

The price data tells its own story. SIS never needed to go near its cap, and the buying range of ₹391.91 to ₹436.11 shows where the company was willing to absorb supply over those two months. Treat that as a record of what happened, not a floor. With the buyback over, that steady buyer is no longer in the order book.

The figures here come from the company’s exchange filings.

SEBI’s buyback rules themselves are on the SEBI regulations page.

Next thing to watch: the final extinguishment of the last 3,28,540 shares by October 29, which will bring the reported share count into line with the post-buyback numbers above.
