RANDY NEELY, PRESIDENT AND CEO's STATEMENT

"We are starting 2022 off on great footing in both Egypt and Canada. With the ratification of our consolidated agreement now complete, we will be finalizing our capital program for Egypt shortly. In Canada, the latest well results exceeded our expectations and continue to increase our confidence in the extent of the play in the South Harmattan area, where we hold 22.5 net sections of lands.

Our focus continues to be creating value for our stakeholders. We are very encouraged by the opportunities we have to deploy capital on value accretive projects across our portfolio. It remains our expectation that we will be able to fund our 2022 capital program through free cash flow generated by our operations, and with supportive commodity prices, we intend to revisit our dividend policy in the coming months as the balance sheet strengthens."

PRODUCTION

Production Summary (WI before royalties and taxes):

* See "Oil & Gas Advisories" for production by product type.

Company production met the upper end of production guidance for 2021 of 12-13 MBoepd. In Egypt this was principally due to the re-commencement of Eastern Desert drilling in Q2, 2021 in response to the anticipated approval of the new Agreement. Canadian production was boosted by placing the new horizontal wells on production.

OPERATIONS UPDATE

Arab Republic of Egypt

Eastern Desert (100% WI)

The Company continued to use the EDC-64 rig in its Eastern Desert drilling campaign, managing to drill and case three additional development wells in K-Field and H-Field during the quarter.

K-66 was drilled to a total depth of 1,809 meters, encountering good gas and oil shows in the Asl-A, Asl-B, Asl-D, Asl-E, and Asl-F reservoirs. Hole instability issues prevented wireline logging of certain zones, however the Asl-A and Asl-B were logged and evaluated, with an internally estimated 25.1 meters of net oil pay in the Asl-A and 20.3 meters net oil pay in the Asl-B. The Asl-B was perforated, put on production, and is currently producing at a rate of 160 Bopd heavy crude oil (field estimate). The well is expected to be recompleted on the Asl-A once the Asl-B is exhausted. The deeper zones encountered by the well, the Asl-D, Asl-E, and Asl-F reservoirs, are being considered as targets in future drilling. Heavy crude is the expected product type for all zones mentioned.

HE-2 was drilled to 1,800 meters total depth, encountering an internally estimated net oil pay of 4 meters in the Asl-B reservoir after being fully logged and evaluated. The expected product type is heavy crude. The well was perforated in the Asl-B and is currently on production at a rate of 220 Bopd heavy crude oil (field estimate).

K-68 was drilled to a total depth of 1,403 meters. The well was fully logged and evaluated, with an internally estimated 22.9 meters of net oil pay in the Asl-A reservoir and 4.6 meters of net oil pay in the Asl-B reservoir. The well will be perforated in the Asl-A reservoir and put on production in January 2022. The Asl-B is expected to be recovered through existing up-dip completions on that reservoir. Both zones are expected to be heavy crude oil.

Subsequent to the quarter the EDC-64 rig is being moved to the K-67 well location, in the K-Field.

As previously disclosed, the Company announced a merged concession agreement with a 15-year primary term and improved Company economics in early December, 2020, and parliamentary ratification and Presidential signature into law of the new Agreement in December, 2021. The Company and Egyptian counterparties anticipate signing the new Agreement, along with payment by the Company of the first modernization payment ($15 million) and signature bonus ($1 million), in the coming weeks. The effective date for the improved concession terms in the new Agreement is February 1, 2020.

The Company is in the process of finalizing a 2022 work program and budget that reflects our focus on free cash flow through continued development activities on the contingent resource projects previously disclosed, and production-sustaining infrastructure improvements. The Company anticipates maintaining a single drilling rig, along with a light rig for well maintenance and recompletion activities in the Eastern Desert throughout 2022.

Western Desert - South Ghazalat (100% WI)

Natural flow of SGZ-6X well at South Ghazalat ceased in December due to low reservoir pressure, and rigless-deployed artificial lift equipment has been mobilized to site in an attempt to restore production. Immediately prior to the well ceasing production, the lower Bahariya reservoir at SGZ-6X was producing at a field estimated 240 Bopd of light crude oil with a 71.5% watercut.

Initial well testing of the oil-bearing lower Bahariya reservoir discovered in the SGZ-7B exploration well drilled in October, 2021 has indicated low productivity and sub-commercial flowrates. The well has been suspended pending further evaluation of options to improve productivity on the lower Bahariya reservoir, and to assess the commercial potential of the gas-bearing upper Bahariya reservoir.

Canada

The three 100% working interest South Harmattan horizontal Cardium reservoir wells, successfully brought into production in Canada in September and October, 2021, were equipped with pumps after the initial flowback post-stimulation. All three wells initially flowed without artificial lift, with the 2-mile well (04-02) brought on production first, flowing unassisted for 47 days prior to installation of a pump.

New well production summary (working interest)*:

* See "Oil & Gas Advisories" for Initial Production by product type.
**On a producing day basis

Although the production history is relatively short and not necessarily indicative of long-term performance or ultimate recovery, the Company is encouraged about the results, which are significantly above internal type curve expectations for the area on both the 1 and 2-mile wells.

Further development activity focused on increasing production and further reducing uncertainty is anticipated in South Harmattan in 2022. The Company holds 22.5 sections of land in the South Harmattan area.

CORPORATE

The Company has a cargo of Gharib blend crude, marketed by Mercuria Energy Trading, scheduled to ship at the end of January and with proceeds expected by the beginning of March, 2022.

In December 2021 TransGlobe entered into costless collar natural gas hedges for 2022 with ATB Financial. Below are the Company's open hedge positions as of December 31, 2021:

As previously disclosed, the amounts outstanding under the Mercuria prepayment agreement were repaid in full during 2021. The Company's remaining debt at year end was $3.0 million outstanding against the $17.7 million ATB Financial credit facility.

TransGlobe collected ~$27 million of receivables in Q4, 2021 and ended the year with over $37 million of cash and no net debt.

Oil and Gas Advisories

Mr. Ron Hornseth, B.Sc., General Manager - Canada for TransGlobe Energy Corporation, and a qualified person as defined in the Guidance Note for Mining, Oil and Gas Companies, June 2009, of the London Stock Exchange, has reviewed the technical information contained in this report. Mr. Hornseth is a professional engineer who obtained a Bachelor of Science in Mechanical Engineering from the University of Alberta. He is a member of the Association of Professional Engineers and Geoscientists of Alberta ("APEGA") and the Society of Petroleum Engineers ("SPE") and has over 20 years' experience in oil and gas.

BOEs may be misleading, particularly if used in isolation. A BOE conversion ratio of six thousand cubic feet of natural gas to one barrel of oil equivalent (6 MCF: 1 Bbl) is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. Given that the value ratio based on the current price of crude oil as compared to natural gas is significantly different from the energy equivalency of 6:1, utilizing a conversion on a 6:1 basis may be misleading as an indication of value.

Further, this press release includes estimates of pay thickness and production rates in the K-Field and H-Field in the Eastern Desert of Egypt (100% WI), which are considered to be anticipated results or information that indicate the potential value or quantities of resources under National Instrument 51-101 - Standards of Disclosure for Oil and Gas Activities because the disclosure in question may, in the opinion of a reasonable person, indicate the potential value or quantities of resources in respect of the Company's resources or a portion of its resources. Such estimates have been prepared internally by management of TransGlobe and have not been prepared or reviewed by an independent qualified reserves evaluator or auditor. Anticipated results are subject to certain risks and uncertainties, including those described above under "Advisory on Forward-Looking Information and Statements" and various geological, technical, operational, engineering, commercial, and technical risks, including, but not limited to, the risk that TransGlobe's exploration and development drilling and related activities may provide different results; the risk that TransGlobe may encounter unexpected drilling results; the occurrence of unexpected events involved in the exploration for, and the operation and development of, oil and gas; delays in anticipated timing of drilling and completion of wells; geological, technical, drilling and processing problems and other difficulties in producing petroleum reserves; and the risk that if any resources are discovered that it will not be commercially viable to produce any portion thereof. In addition, the geotechnical analysis and engineering to be conducted in respect of such resources is not complete. Such risks and uncertainties may cause the anticipated results disclosed herein to be inaccurate. Actual results may vary, perhaps materially. There is no certainty that TransGlobe will achieve the anticipated results from the K-Field and H-Field in the Eastern Desert of Egypt or that any resources will be discovered. If discovered, there is also no certainty that it will be commercially viable to produce any portion of the resources.

References in this press release to production test rates, IP30, IP60 and initial production rates are useful in confirming the presence of hydrocarbons, however such rates are not determinative of the rates at which such wells will continue production and are not indicative of long term performance or of ultimate recovery. While encouraging, readers are cautioned not to place reliance on such rates in calculating the aggregate production for TransGlobe. A pressure transient analysis or well-test interpretation has not been carried out in respect of all wells. Accordingly, the Company cautions that production test results and initial production results should be considered to be preliminary.

The following abbreviations used in this press release have the meanings set forth below:
