Adjustment of PATANJALI F&O contracts after bonus issue

Patanjali has announced a bonus issue in the ratio 2:1 (2 new shares for every 1 share held). Because of this, all Futures & Options (F&O) contracts on the stock will be adjusted from September 11, 2025.

For equity shareholders: If you hold Patanjali shares on the ex-date (September 11, 2025), you will get 2 bonus shares for every 1 share you hold. The new shares will be credited to your demat account within 2 working days from the record date. 

How the adjustment factor is calculated

• Formula: (A + B) / B, where A:B is the bonus ratio.
• For Patanjali (2:1), the factor = (2+1)/1 = 3. 
   

Futures Contracts 

• Price adjustment: The closing price on the day before the ex-date will be divided by 3. 
  • Example: If PATANJALI SEP FUT closed at ₹1830 on Sep 10, the adjusted price on Sep 11 will be ₹610 (1830 ÷ 3). 
• Lot size adjustment: The current lot size will be multiplied by 3.
  • Example: Current lot size = 300 → New lot size = 900. 
     

Options Contracts 

• Strike price adjustment: Old strike prices will be divided by 3. 
  • Example: A ₹1800 CE becomes a ₹600 CE. 
• Lot size adjustment: Current lot size (300) × 3 = 900.
