AGM and operational update

Cabot Energy (AIM:CAB), the AIM quoted oil and gas company focused on production led growth balanced with high impact exploration and appraisal opportunities, will hold its annual general meeting later today and Keith Bush, the Company's Chief Executive Officer, will be making a presentation to shareholders. In advance of the AGM, the Company is providing the following operational update.

§ As previously announced, the Company has completed its Canadian winter work programme in Rainbow which included the drilling of four new side track wells

- latest combined production test rate from the four wells is line with expectation at approximately 350 bopd

§ In addition, the Company was required to invest additional capital in the infrastructure of the Rainbow assets, including pipeline replacement and integrity work, abandonments and well workover activity

§ The planned summer drilling programme will now be deferred in order to:

- fully integrate the operational data obtained from the winter work programme

- confirm the production performance of the new wells over an extended period

- manage group capital requirements

§ The Company is assessing a potential well reinstatement programme during the summer of 2018 on a number of existing wells to increase production

§ With the changes to the summer work programme, the production for the year is expected to be below previous guidance and the Company will provide new guidance once the programme for the second half of the year has been finalised

§ The Company's average production during April was 851 bopd and average sales for the month was 914 bopd, with seasonal road bans impacting production during the second half of the month from single well batteries

Keith Bush, Chief Executive Officer of Cabot Energy, commented:

"Understanding the performance of the new wells is important for the long term development of the Rainbow assets and the deferral of the summer work programme is a prudent step to maximise oil recovery over the medium to long term.

"The valuable lessons learned from the winter drilling programme will enable more cost effective well options to be developed, including the drilling of new wells as opposed to side track wells, which is expected to improve the development of the area."

Cabot Energy will make available a copy of the presentation on its website later today. The presentation contains no previously unpublished information that could be considered price sensitive.
