OTTAWA, CANADA – July 12, 2017 – DragonWave Inc. (TSX:DRWI; NASDAQ:DRWI) a leading global supplier of packet microwave radio systems for mobile and access networks, today announced financial results for the first quarter of fiscal year 2018. All figures are in U.S. dollars and were prepared in accordance with U.S. generally accepted accounting principles ("GAAP").

This press release contains certain information that is not consistent with financial measures prescribed under GAAP. We break out "Gross profit before inventory provisions" as this measure allows management to evaluate our operational performance and compare to prior periods more effectively. "Gross profit before inventory provisions" does not have any standardized meaning prescribed by GAAP, it is therefore unlikely to be comparable to similar measures presented by other issuers and is not designed to replace other measures of financial performance or the statement of operations as an indicator of performance. This measure should not be considered in isolation or as a substitute for other measures of performance calculated according to GAAP. We believe that it is useful to compare gross profit results without the impact of inventory provisions, since our inventory provisions generally relate to technical obsolescence and excess due to market changes. We believe this non-GAAP measure also provides investors with a better ability to understand our operational performance. We calculate "Gross profit before inventory provisions" consistently over each fiscal period.

The most directly comparable GAAP measure presented in our consolidated financial statements for the three months ended May 31, 2017 to "Gross profit before inventory provisions" is "Gross profit".
