Calgary, Alberta, May 13, 2019 - TransGlobe Energy Corporation ("TransGlobe" or the "Company") is pleased to announce its financial and operating results for the three months ended March 31, 2019. All dollar values are expressed in United States dollars unless otherwise stated. TransGlobe's Condensed Consolidated Interim Financial Statements together with the notes related thereto, as well as TransGlobe's Management's Discussion and Analysis for the three month periods ended March 31, 2019 and 2018, are available on TransGlobe's website at www.trans-globe.com.

FINANCIAL AND OPERATING RESULTS

(US$000s, except per share, price, volume amounts and % change)

CORPORATE SUMMARY

TransGlobe Energy Corporation ("TransGlobe" or the "Company") produced an average of 15,924 barrels of oil equivalent per day ("boe/d") during the first quarter of 2019. Egypt production was 13,616 barrels of oil per day ("bbls/d") and Canada production was 2,308 boe/d. Production for the quarter was above the 2019 guidance (14,000 - 15,000 boe/d) and 4% higher than the previous quarter.

As at March 31, 2019 the Company had approximately 647.0 thousand barrels ("mbbls") of inventoried entitlement crude oil. All Canadian production was sold during the quarter, and the Company sold 452.6 mbbls of entitlement crude oil in Egypt.

TransGlobe's Egyptian crude oil is sold at a quality discount to Dated Brent. The Company received an average price of $54.93 per barrel during the quarter. In Canada, the Company received an average of $48.53 per barrel of oil and $1.94 per thousand cubic feet ("mcf") of natural gas in the first quarter of 2019.

During the first quarter of 2019, the Company had funds flow from operations of $15.2 million and ended the quarter with positive working capital of $43.6 million, including cash and cash equivalents of $24.7 million. The Company experienced a net loss in the quarter of $8.8 million, which included an $8.4 million non-cash impairment loss on the Company's exploration and evaluation assets in South Alamein and a $4.8 million unrealized derivative loss on commodity contracts which represents a fair value adjustment on the Company's hedging contracts as at March 31, 2019.

The Company declared a dividend of $0.035 per share, paid on April 18, 2019 to shareholders of record on March 29, 2019.

In the Eastern Desert the Company drilled two development oil wells during the first quarter of 2019. At West Bakr, the Company drilled and completed the M-10 replacement well (M-10 Twin) as an Asl A oil producer which was placed on production in February and is currently producing ~400 bbls/d. The Company also re-entered/deepened two suspended oil wells and converted them to water disposal wells (K-8 WDW and K-10 WDW). At North West Gharib, the Company drilled the NWG 38A-8 well to a total depth of 1,631 meters (5,350 feet), targeting the southern area of the NWG 38A Red Bed pool to provide water injection/reservoir pressure support for the 38A pool. The well was completed and placed on production at an initial average rate of 45 bbls/d and 100 barrels per day of water. Based on early production results, the well was converted to water injection during Q2-2019 to initiate pressure support for the NWG 38A pool.

Subsequent to the quarter, the Company drilled two wells in West Bakr resulting in an oil discovery at HW-2X and a development oil well at H-30. The HW-2X exploration well was drilled to a total depth of 1,654 meters (5,425 feet) and cased as a Yusr oil well. Based on open-hole logs and wireline samples, the well encountered an internally estimated 34.5 meters (113 feet) of net oil pay in the Yusr formation. The HW-2X well was completed and placed on production in early May at an initial rate of ~625 bbls/d. The H-30 development well was drilled to a total depth of 1,655 meters (5,454 feet) and cased as a Yusr oil well. Based on open-hole logs and wireline samples, the well encountered an internally estimated 7.8 meters (25 feet) of net oil pay in the Yusr formation. The H-30 well is scheduled for completion and first oil production by the end of May. Following H-30, the drilling rig is scheduled to drill a development well at West Bakr (K-63) and one exploration well at North West Gharib (NWG 38 D-1).

In the Western Desert, the Company filed a development lease application with EGPC in February for the South Ghazalat SGZ 6X oil discovery. The Company is targeting production from this concession prior to year end. At South Alamein, the Company was unsuccessful in its attempts to secure military approval for its desired drilling location. In light of recent events, TransGlobe has recorded an impairment loss of $8.4 million and will continue to negotiate access to the western portion of this concession.

In Canada, the Company equipped and tied in six (five net) Cardium oil wells (from the 2018 capital program) in the Harmattan area during January. Due to low ethane prices, TransGlobe's third-party gas processing plant shut down their deep cut ethane extraction plant in January. Approximately 250 boe/d of ethane was sold as part of the gas stream in Q1-2019 at a higher energy content resulting in a neutral impact to revenue. It is expected that ethane volumes will remain in sales gas volumes until Q4-2019.

Oil and Gas Advisories

Mr. Darrin Drall, P.Eng., - Manager Engineering 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 and approved the technical information contained in this announcement. Mr. Drall obtained a Bachelor of Science Degree in Engineering from the University of Manitoba. He is a Registered Professional Engineer in the province of Alberta (Association of Professional Engineers and Geoscientists of Alberta) and in the province of Saskatchewan (Association of Professional Engineers and Geoscientists of Saskatchewan) and has over 30 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.

References in this press release to production test rates, are useful in confirming the presence of hydrocarbons, however such rates are not determinative of the rates at which such wells will commence production and decline thereafter 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 the production test results should be considered to be preliminary.
