We report the following spectroscopic classifications of supernova candidates discovered by the Dark Energy Survey (ATel #4668) made from spectra obtained with the GMOS spectrograph on Gemini-South. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024), indicating that both candidates are Type Ia supernovae near maximum brightness. These two transients are the highest redshift spectroscopically-classified supernovae from DES to date.
