On a GAAP basis, net loss for first fiscal quarter ended September 30, 2013 was $7.2 million, or $0.07 per share, compared with a net loss of $8.7 million, or $0.09 per share, in the prior quarter, and with a net loss of $15.1 million, or $0.17 per share, in the September quarter of the preceding year.

On a non-GAAP basis, net loss for the first fiscal quarter ended September 30, 2013 was $6.6 million, or $0.06 per share, compared with a net loss of $6.5 million, or $0.07 per share, in the prior quarter, and with a net loss of $8.1 million, or $0.09 per share, in the September quarter of the preceding year.

Non-GAAP Measure

The Company’s stated results include the non-GAAP measures: non-GAAP net loss and non-GAAP net loss per share. These non-GAAP measures exclude certain items that generally are non-recurring events or are non-cash items that many other companies exclude, in order to compare Unwired Planet with other companies, such as stock-based compensation. These non-GAAP measures also exclude items which management does not consider in evaluating Unwired Planet’s on-going business, such as restructuring costs and discontinued operations. Unwired Planet considers non-GAAP net loss to be an important metric because it provides a useful measure of the operational performance of Unwired Planet and is used by Unwired Planet’s management for that purpose. In addition, investors often use measures such as these to evaluate the financial performance of a company. These non-GAAP measures are presented for supplemental informational purposes only for understanding Unwired Planet’s operating results. These non-GAAP results should not be considered a substitute for financial information presented in accordance with generally accepted accounting principles, and may be different from non-GAAP measures used by other companies.
