Exhibit 99.1 REPORT OF INDEPENDENT ACCOUNTANTS To the Board of Directors and Stockholders of CD Radio Inc.: We have audited the accompanying consolidated balance sheets of CD Radio Inc. and Subsidiary (a Development Stage Enterprise) as of December 31, 1996 and 1997, and the related consolidated statements of operations, stockholders' equity and cash flows for each of the three years in the period ended December 31, 1997 and for the period May 17, 1990 (date of inception) to December 31, 1997. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with generally accepted auditing standards. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our previously issued report, dated March 3, 1998 and October 7, 1998, on our audits of the aforementioned consolidated financial statements, we included an explanatory paragraph describing certain uncertainties with respect to the availability of funds to sustain the Company's activities through 1999. Subsequent to that report, the Company has obtained additional funding as described in Item 5 of the Company's Form 8-K, filed on December 10, 1998. This funding alleviates those uncertainties that the Company may be able to continue as a going concern through 1999. In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of CD Radio Inc. and Subsidiary as of December 31, 1996 and 1997, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 1997 and for the period May 17, 1990 (date of inception) to December 31, 1997 in conformity with generally accepted accounting principles. /s/ PricewaterhouseCoopers LLP ------------------------------ McLean, VA March 3, 1998, except as to the third paragraph for which the date is December 10, 1998. 5
