EXPLANATORY NOTE

ORBCOMM Inc. (the “Company”) is filing this Amendment No. 1 on Form 10-K/A (the “Form 10-K/A”) to its Annual Report on Form 10-K for the year ended December 31, 2014, as filed with the Securities and Exchange Commission (the “SEC”) on March 16, 2015 (the “Form 10-K”), in order to amend Part II, Item 9A of the Form 10-K solely for the purpose of including the disclosure under “Disclosure Controls and Procedures” of Part II, Item 9A that was inadvertently omitted in the Form 10-K. There are no changes to the other sections of Part II, Item 9A. We are including in this Form 10-K/A the complete text of Part II, Item 9A and Part IV, Item 15, as well as updated certifications as described in the following paragraph.

As required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended, and Section 906 of the Sarbanes-Oxley Act of 2002, new certifications by our principal executive officer and principal financial officer are filed as Exhibits 31.3, 31.4 and 32.2 to this Form 10-K/A. In addition, a new consent of KPMG LLP is filed as Exhibit 23.2 to this Form 10-K/A.

Except for the foregoing, no changes have been made to the Form 10-K. This Form 10-K/A does not reflect events occurring after the original filing of the Form 10-K and no attempt has been made in this Form 10-K/A to modify or update other disclosures as presented in the original filing of the Form 10-K. Accordingly, this Form 10-K/A should be read in conjunction with our filings with the SEC subsequent to the original filing of the Form 10-K.

Item 9A.    Controls and Procedures

Disclosure Controls and Procedures

In connection with preparation of this Annual Report on Form 10-K, we carried out an evaluation, under the supervision and with the participation of our management including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2014. The term “disclosure controls and procedures”, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2014, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Exchange Act Rule 13a-15(f). Management, including our Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework set forth in Internal Control-Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission. As a result of the acquisition of Euroscan Holding B.V. (“Euroscan”), we have begun to integrate certain business processes and systems of Euroscan. Accordingly, certain changes have been made and will continue to be made to our internal control over financial reporting until such time as this integration is complete. In reliance on interpretive guidance issued by the SEC staff, management has chosen to exclude from its assessment of the effectiveness of our internal control over financial reporting as of December 31, 2014, Euroscan’s internal control over financial reporting associated with assets of $6.4 million representing 1.3% of consolidated assets, and revenue of $12.6 million, representing 13.1% of consolidated revenues, included in our consolidated financial statements as of and for the year ended December 31, 2014, and will include its assessment of internal control over financial reporting for Euroscan in our Annual Report on Form 10-K for our fiscal year ending December 31, 2015. Based on this evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2014. The effectiveness of our internal control over financial reporting as of December 31, 2014 has been audited by KPMG LLP, an independent registered public accounting firm, as stated in its attestation report which is included below.

Changes in Internal Control over Financial Reporting

We reviewed our internal control over financial reporting at December 31, 2014. As a result of the acquisition of Euroscan, we have begun to integrate certain business processes and systems of Euroscan. Accordingly, certain changes have been made and will continue to be made to our internal controls over financial reporting until such time as this integration is complete.

There have been no other changes in our internal control over financial reporting identified in an evaluation thereof that occurred during the last fiscal quarter of 2014 that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

ORBCOMM Inc.:

We have audited ORBCOMM Inc. and subsidiaries’ (the Company) internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control — Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). 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 Management’s 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, and 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, ORBCOMM Inc. and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2014, based on criteria established in Internal Control — Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

ORBCOMM Inc. acquired Euroscan Holding B.V. and subsidiaries (“Euroscan”) during 2014 and management excluded from its assessment of the effectiveness of ORBCOMM Inc’s internal control over financial reporting as of December 31, 2014, Euroscan’s internal control over financial reporting associated with total assets of $6.4 million, representing 1.3% of consolidated assets, and revenues of $12.6 million representing 13.1% of consolidated revenues, included within the consolidated financial statements of ORBCOMM Inc. and subsidiaries as of and for the year ended December 31, 2014. Our audit of internal control over financial reporting of ORBCOMM Inc. also excluded an evaluation of the internal control over financial reporting of Euroscan.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of ORBCOMM Inc. and subsidiaries as of December 31, 2014 and 2013, and the related consolidated statements of operations, comprehensive (loss) income, cash flows and changes in equity for each of the years in the three-year period ended December 31, 2014, and our report dated March 13, 2015 expressed an unqualified opinion on those consolidated financial statements.
