ITEM 8. FINANCIAL STATEMENTS AND
SUPPLEMENTARY DATA



Report of Independent Registered Public
Accounting Firm



Board of Directors and Stockholders

Elephant Talk Communications Corp.

Schiphol, The Netherlands



We have audited Elephant Talk Communications
Corp.’s (the “Company”) internal control over financial reporting as of December 31, 2012, based on criteria
established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway
Commission (the “COSO criteria”). The Company’s management is responsible for maintaining effective internal
control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included
in the accompanying Item 9A, Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility
is to express an opinion on the Company’s internal control over financial reporting based on our audit.



We conducted our audit in accordance with
the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all
material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk
that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the
assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe
that our audit provides a reasonable basis for our opinion.



A company’s internal control over
financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and
the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s
internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records
that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with
generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with
authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the
financial statements.



Because of its inherent limitations, internal
control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness
to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree
of compliance with the policies or procedures may deteriorate.



In our opinion, the Company maintained,
in all material respects, effective internal control over financial reporting as of December 31, 2012, based on the COSO criteria.



We also have audited, in accordance with
the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of the Company
as of December 31, 2012 and 2011, and the related consolidated statements of operations and comprehensive loss, stockholders’
equity, and cash flows for each of the three years in the period ended December 31, 2012 and our report dated April 2, 2013 expressed
an unqualified opinion thereon and included an explanatory paragraph regarding the Company’s ability to continue as a going
concern.

REPORT OF INDEPENDENT REGISTERED PUBLIC
ACCOUNTING FIRM



Board of Directors and Stockholders

Elephant Talk Communications Corp.

Schiphol, The Netherlands



We have audited the accompanying consolidated
balance sheets of Elephant Talk Communications Corp. (the “Company”), as of December 31, 2012 and 2011 and the related
consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows for each of the three
years in the period ended December 31, 2012. 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
the standards of the Public Company Accounting Oversight Board (United States). 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, 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 opinion, the consolidated financial
statements referred to above present fairly, in all material respects, the financial position of the Company, at December 31, 2012
and 2011, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2012,
in conformity with accounting principles generally accepted in the United States of America.



The accompanying financial statements have
been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the consolidated financial
statements, the Company has suffered recurring losses from operations, has an accumulated deficit of $203.3 million and continues
to generate negative cash flows. These factors, among others discussed in Note 2, raise substantial doubt about its ability to
continue as a going concern. Management’s plans in regard to these matters are also described in Note 2. The consolidated
financial statements do not include any adjustments that might result from the outcome of this uncertainty.



We also have audited, in accordance with
the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial
reporting as of December 31, 2012, based on criteria established in Internal Control—Integrated Framework issued
by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) and our report dated April 2, 2013 expressed an
unqualified opinion thereon.
