BUENOS AIRES, Argentina, May 29, 2018, Madalena Energy Inc. ("Madalena" or the "Company") (TSXV:MVN) (OTCQX:MDLNF) announces its operating and financial results for the three months ended March 31, 2018.  Selected information is outlined below and should be read in conjunction with Madalena's unaudited condensed interim consolidated financial statements for the three months ended March 31, 2018 and the associated management's discussion and analysis ("MD&A, which are available for review under the Company's profile at www.sedar.com and on the Company's website at www.madalenaenergy.com.

                                                          SUMMARY FINANCIAL AND OPERATIONAL RESULTS

1. This table contains the term "funds flow from continuing operations", which is a non-GAAP measure and should not be considered an alternative to, or more meaningful than "cash flows from operating activities " as determined in accordance with International Financial Reporting Standards ("IFRS") as an indicator of the Company's performance. Funds flow from operations and funds flow from operations per share (basic and diluted) do not have any standardized meanings prescribed by IFRS and may not be comparable with the calculation of similar measures for other entities. Management uses funds flow from continuing operations to analyze operating performance and considers funds flow from continuing operations to be a key measure as it demonstrates the Company's ability to generate the cash necessary to fund future capital investment. The reconciliation between funds flow from continuing operations and cash flows from operating activities can be found in the MD&A. Funds flow from continuing operations per share is calculated using the basic and diluted weighted average number of shares for the period, consistent with the calculations of earnings (loss) per share.
2. Operating netback is a non-GAAP measure calculated as the average per boe of the Company's oil and gas sales, less royalties and operating costs.

Meaning of Boe
The term "boe" or barrels of oil equivalent 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. Additionally, 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 ratio of 6:1 may be misleading as an indication of value.

Well Test Results
Well test results should be considered as preliminary and not necessarily indicative of long-term performance or of ultimate recovery. Neither a pressure transient analysis nor a well-test interpretation has been carried out on the well test data contained herein and therefore the data contained herein should be considered to be preliminary until such analysis or interpretation has been done.
