Diffusion Engineers Limited has announced a significant reduction in shareholding by 3P Investment Managers Private Limited, which disposed of 9.82 lakh shares through open market transactions. The disclosure was made under SEBI's Substantial Acquisition regulations following the completion of the transaction on December 22, 2025.

Transaction Details

The investment manager executed the disposal of 9,82,476 equity shares, representing 2.63% of Diffusion Engineers' total paid-up capital. The transaction was conducted through open market sales with the trade date recorded as December 22, 2025, and settlement completed on December 23, 2025.

Shareholding Changes

The disposal resulted in a substantial reduction in 3P Investment Managers' stake in the engineering company. Prior to this transaction, the fund held 19,93,729 shares representing 5.33% of the company's equity capital.

Regulatory Compliance

3P Investment Managers Private Limited serves as the investment manager for 3P India Equity Fund, which is registered with SEBI as a Category III Alternative Investment Fund. The disclosure was made under Regulation 29(2) of SEBI's Substantial Acquisition of Shares and Takeovers Regulations, 2011.

The fund had previously disclosed crossing the 5% threshold in October 2024 when it first acquired substantial shareholding in Diffusion Engineers. Since then, the fund had made several smaller disposals that individually did not trigger disclosure requirements, but the December 22 transaction resulted in cumulative disposal exceeding the 2% reporting threshold.

Diffusion Engineers Limited has announced a significant change in its Senior Management Personnel (SMP) structure, effective December 11, 2025. The modification stems from an internal reporting restructuring within the organization and has been disclosed in compliance with SEBI regulations.

Senior Management Personnel Change

The company has informed stock exchanges that Mr. Sameer Khaladkar, Vice President of Exports, will no longer fall under the definition of Senior Management Personnel as per Regulation 16(1)(d) of SEBI Listing Regulations. The change will take effect from the close of business hours on December 11, 2025.

Employment Continuity

Importantly, this change does not represent a cessation of employment. Mr. Khaladkar will continue working with Diffusion Engineers under the new reporting structure. The modification is purely administrative and reflects the company's internal organizational restructuring rather than any personnel departure.

Regulatory Compliance

The announcement has been made pursuant to Regulation 30 read with Schedule III of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015. The company has provided all required information as mandated by SEBI Master Circular No. SEBI/HO/CFD/PoD2/CIR/P/0155 dated November 11, 2024, and SEBI Circular No. SEBI/HO/CFD/CFD-PoD-2/CIR/P/2024/185 dated December 31, 2024.
