**Non-GAAP Financial Measures**

In addition to reporting financial measures in accordance with generally accepted accounting principles ("GAAP"), the Company is including in this press release "non-GAAP adjusted product gross margin," "non-GAAP adjusted product gross margin percentage," "non-GAAP adjusted total gross margin," and "non-GAAP adjusted total gross margin percentage," all of which are non-GAAP financial measures. The Company defines non-GAAP adjusted product gross margin as product gross margin adjusted for certain charges to write-off unusable inventory and related warranty expense. Non-GAAP adjusted product gross margin percentage is defined as non-GAAP adjusted product gross margin divided by product revenue. The Company defines non-GAAP adjusted total gross margin as total gross margin adjusted for certain charges to write-off unusable inventory and related warranty expense. Non-GAAP adjusted total gross margin percentage is defined as non-GAAP adjusted total gross margin divided by total revenue.

The Company includes these non-GAAP financial measures because it believes they allow investors to understand and evaluate the Company's core operating performance and trends. In particular, the exclusion of certain items in calculating non-GAAP adjusted product gross margin, non-GAAP adjusted product gross margin percentage, non-GAAP adjusted total gross margin, and non-GAAP adjusted total gross margin percentage can provide useful measures for period-to-period comparisons of the Company's core business. These non-GAAP financial measures have limitations as analytical tools, including the fact that such non-GAAP financial measures may not be comparable to similarly titled measures presented by other companies because other companies may calculate non-GAAP adjusted product gross margin, non-GAAP adjusted product gross percentage, non-GAAP adjusted total gross margin, and non-GAAP adjusted total gross margin percentage differently than the Company does. For more information regarding these non-GAAP financial measures, see the tables included at the end of this press release.
