Houston, Texas – March 31, 2021 – Cub Energy Inc. (“Cub” or the “Company”) (TSX-V: KUB)

announces the results of its independent reserves evaluations as of December 31, 2020 on its oil and gas properties in Ukraine. The evaluation was performed on the Company’s 35% working interest in KUB-Gas LLC (“KUB-Gas”) and was conducted by Ryder Scott Petroleum Consultants (“Ryder Scott”), an independent qualified reserves evaluators and auditor (“Reserves Report”).

The 100% owned RK field, held by the Company’s wholly-owned subsidiary Tysagaz LLC, was not subject to a Reserve Report in 2020 given the Company is awaiting the commencement of commercial production at the power generation project which will utilize the gas at the RK field. The Company expects to re-evaluate the reserve category of the RK field in 2021.

Patrick McGrath, Interim CEO of Cub said: “The natural gas price assumptions in the 2020 reserve report were approximately 15%-20% lower than the World Bank forecasts for the same period which had a negative impact on the value of the 2020 reserve results. However, to date in 2021, the Company has seen the price of natural gas in Ukraine rebound to the $5/Mcf-$6/Mcf range. In addition, the Company hopes to have its RK field re-evaluated to a reserve category in 2021 upon the material re-start of the RK field.”

All evaluations were prepared using guidelines outlined in the Canadian Oil and Gas Evaluation

Handbook ("COGE Handbook") and are in accordance with Canadian Securities Administrators

National Instrument 51-101 - Standards of Disclosure for Oil and Gas Activities ("NI 51-101"). Cub’sNI 51-101 disclosure for the year ended December 31, 2020 is in its Form 51-101 F1 filed on SEDAR www.sedar.com and posted on the Company’s website at www.cubenergyinc.com
