Key Highlights of Volume Handled:

 Inter State Oil Carrier Limited handled 23.12 (‘000 MTs) of volume in May 2026, reflecting a

decline of approximately 4.79% compared to 24.28 (‘000 MTs) handled in April 2026.

• The volume of 23.12 (‘000 MTs) handled in May 2026 indicates a marginal decline of

approximately 7.22% compared to 24.92 (‘000 MTs) handled in May 2025.

Note:

1. The decline in volume handled during May 2026 was primarily attributable to disruptions

in transportation movement and operational challenges arising from the prevailing war-like

situation and the related market uncertainties, which adversely impacted logistics activities

during the period.

2. The Company strengthened its fleet capacity by onboarding four additional tankers during

the month.
