TRIANGLE PETROLEUM TO RECOGNIZE GAIN ON CALIBER INVESTMENT FOR FISCAL YEAR 2014 AND RESCHEDULES FOURTH QUARTER AND FULL FISCAL YEAR 2014 FINANCIAL AND OPERATIONAL RESULTS CONFERENCE CALL

DENVER, Colorado, April 14, 2014 — Triangle Petroleum Corporation (“Triangle” or the “Company”) (NYSE MKT: TPLM) announces today that it expects to recognize a gain on its investment in Caliber Midstream Partners, L.P. (“Caliber”) for fiscal year 2014, that it has rescheduled its fourth quarter and full fiscal year 2014 financial and operational results conference call to Thursday, April 17, 2014 at 8:30 AM MT (10:30 AM ET), and that it intends to file its fiscal year 2014 Annual Report on Form 10-K with the Securities and Exchange Commission (the “SEC”) on Wednesday, April 16, 2014.

Triangle to Recognize Gain on Investment in Caliber for Fiscal Year 2014

During preparation of its fiscal year 2014 audited financial statements, the Company concluded, after consultation with KPMG LLP, the Company’s independent auditor, that it should recognize a gain in fiscal year 2014 on the fair value of the Company’s trigger units, trigger unit warrants, and warrants in Caliber, the Company’s midstream services joint venture. The gain recognition results from the classification of the trigger units, trigger unit warrants, and warrants as equity investment derivatives, which are revalued periodically in accordance with U.S. generally accepted accounting principles. The Company expects to recognize a non-cash, pre-tax gain and an increase in Triangle’s equity investment in Caliber of approximately $39.7 million for fiscal year 2014. The Company also plans to file restated financial statements with the SEC under the cover of Form 10-Q/A for the third quarter of fiscal year 2014 (period ended October 31, 2013) to recognize the portion of the associated gain attributable to that period.

Updated Filing Date and Conference Call Information

Triangle has rescheduled its conference call to Thursday, April 17, 2014 at 8:30 AM MT (10:30 AM ET) to provide an operational update and financial results of Triangle’s fourth quarter fiscal year 2014, followed immediately by a question and answer session. Interested parties may dial-in using the conference call number (877) 870-4263. International parties may dial-in using (412) 317-0790. The Company recommends dialing into the conference call at least ten minutes before the scheduled start time.
