with paragraph 5A of Para A of Part A of Schedule III of the SEBI (LODR) Regulations, we
wish to inform you that on October 30, 2026, BP p.l.c. (“bp”) (which immediately before
Closing, was the ultimate holding company of Castrol Limited, the promoter of Castrol
India Limited (“Castrol India”)) and Motion JVCo Limited (“Acquirer”), an entity that is
part of Stonepeak Infrastructure Fund V (“Stonepeak”) completed the transactions
contemplated under the agreement for the sale and purchase dated December 23, 2025
executed between bp and the Acquirer (as amended and/or amended and restated from
time to time) (“SPA”, the foregoing being “Closing”).
Pursuant to the consummation of the transactions under the SPA, the Acquirer has
acquired 100% (one hundred per cent) of the equity share capital of Castrol Group
Holdings Limited (“CGHL”), which in turn holds 100% (one hundred per cent) of the equity
share capital of Castrol Limited. Castrol Limited is the promoter of Castrol India and holds
50,44,52,416 (fifty crore forty-four lakh fifty-two thousand four hundred and sixteen) equity
shares of Castrol India constituting 51.00% (fifty one percent) of the equity share capital of
Castrol India. Consequently, the Acquirer has indirectly acquired sole control of Castrol
Limited, and thereby indirectly acquired: (a) the right to direct the exercise by Castrol
Limited of the voting rights attached to its 50,44,52,416 (fifty crore forty-four lakh fifty two
thousand four hundred and sixteen) equity shares in Castrol India (constituting 51.00%
(fifty one percent) of the total voting rights); and (b) sole control over Castrol India. Simultaneously with the acquisition of the entire equity share capital of CGHL by the
Acquirer, the Acquirer has issued and allotted to BP Motion Holdings Limited (an indirect
wholly owned subsidiary of bp) (“BPMH”), equity shares constituting 35% (thirty five
percent) of the Acquirer’s equity share capital, resulting in BPMH holding a non-controlling
interest in the Acquirer. Please refer to the Company’s disclosure dated December 24, 2025
for further details regarding the consequence of Closing on the other transaction
documents.
