Dear Sir,

We are pleased to inform that Oil and Gas Development Company Limited (OGDCL), as Operator (95%), along with Government Holdings (Private) Limited (GHPL) (5% carried interest), has discovered gas from Sahito-1 exploratory well in Khewari Exploration License, located in District Khairpur, Sindh Province.

Based on wireline logs interpretation results, the sands of Lower Goru Formation (Massive sand) were tested through DST and yielded 17.2 million standard cubic feet of gas per day (MMSCFD) through choke size 32/64" at wellhead flowing pressure (WHFP) of 3390 pounds per square inch (psi).

Sahito-1 was spudded on December 24, 2025, as an exploratory well. The well was drilled down to a total depth of 3870m TVD in the Sembar Formation as an exploratory effort by using OGDCL's in-house expertise.

The discovery represents a major milestone, and this development is anticipated to play a vital role in reducing the national energy demand-supply gap through indigenous resources, while also contributing to the enhancement of hydrocarbon reserves of OGDCL, Joint venture partner and the country.

The above information is submitted in compliance with Section 96 of the Securities Act, 2015, and Clause 5.6.1(a) of PSX Regulations, for dissemination among your members.
