1. The Company and Basis of Presentation

Business

We were incorporated in the state of Delaware on December 19, 2000 as FaxMed, Inc., changed our name to Alexza Corporation in June 2001 and in December 2001 became Alexza Molecular Delivery Corporation. In July 2005, we changed our name to Alexza Pharmaceuticals, Inc.

We are a pharmaceutical company focused on the research, development, and commercialization of novel proprietary products for the acute treatment of central nervous system conditions. We operate in one business segment. Our facilities and employees are currently located in the United States.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not contain all of the information and footnotes required for complete financial statements. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments, necessary to present fairly our interim condensed consolidated financial information. The results for the three and six months ended June 30, 2015 are not necessarily indicative of the results to be expected for the year ending December 31, 2015 or for any other interim period or any other future year.

The accompanying unaudited condensed consolidated financial statements and notes to condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2014 included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission, or SEC, on March 13, 2015.

Basis of Consolidation

The unaudited condensed consolidated financial statements include our accounts and those of our wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated.
