Introduction

This Amendment No. 1 to Schedule 13D (this “Amendment”) relates to the Class A Common Stock, no par value (the “Shares”), of Numerex Corp., a Pennsylvania corporation (the “Issuer”), and amends and supplements certain information disclosed in the initial statement on Schedule 13D filed on August 11, 2017 by the Reporting Persons (the “Original 13D”, and together with this Amendment, the “Schedule 13D”). Unless otherwise specified, capitalized terms used but not otherwise defined in this Amendment shall have the meanings ascribed to them in the Original 13D.

On December 7, 2017, Sierra Wireless, Wireless Acquisition Sub, Inc. (“Merger Sub”) and the Issuer completed the transactions contemplated by the Agreement and Plan of Merger, dated as of August 2, 2017, by and among the Issuer, Sierra Wireless and Merger Sub (the “Merger Agreement”).

Pursuant to the terms of the Voting Agreements, dated as of August 2, 2017, between Sierra Wireless and certain stockholders of the Issuer, the Voting Agreements terminated upon approval of the Merger by the Issuer’s stockholders.

The foregoing descriptions of the Merger Agreement, the Voting Agreements and the transactions contemplated thereby are not intended to be complete and are qualified in their entirety by reference to the Merger Agreement and the Voting Agreements, copies of which are listed as Exhibits hereto and are incorporated herein by reference.

Item 3.

Source and Amount of Funds or Other Consideration

Item 3 of the Original 13D is hereby amended and supplemented by adding the following at the end thereof:

Upon closing of the Merger, and pursuant to the terms of the Merger Agreement, Sierra Wireless issued 3,588,784 common shares, no par value, of Sierra Wireless in exchange for all of the Shares issued and outstanding, representing approximately $3.83 in Sierra Wireless common shares for each Share, or a total estimated price of approximately $76.3 million for the acquisition of all the Shares issued and outstanding.

Item 4.

Purpose of Transaction

Item 4 of the Original 13D is hereby amended and supplemented by adding the following at the end thereof:

On December 7, 2017, pursuant to the terms of the Merger Agreement, Merger Sub merged with and into the Issuer, with the Issuer surviving the Merger as a wholly-owned subsidiary of Sierra Wireless.

At the Effective Time, each Share issued and outstanding immediately prior to the Effective Time was converted into the right to receive 0.1800 common shares, no par value, of Sierra Wireless. Additionally, each outstanding restricted stock unit, in-the-money option and in-the-money stock appreciation right of the Issuer was cancelled in exchange for the right to receive the Merger Consideration in accordance with the terms of the Merger Agreement. Subject to certain exceptions specified in the Merger Agreement, each outstanding warrant issued by the Issuer (with the exception of that certain Warrant, dated as of June 7, 2017, issued by the Issuer to HCP-FVF, LLC) was cancelled in exchange for the right to receive the Merger Consideration or, if not exercised, was otherwise cancelled at the Effective Time.

Pursuant to the terms of the Voting Agreements, the Voting Agreements terminated upon approval of the Merger by the Issuer’s stockholders on December 6, 2017.

Pursuant to the terms of the Merger Agreement, at the Effective Time, all members of the board of directors of the Issuer were replaced by the directors of Merger Sub, respectively. The articles of incorporation and bylaws of the Issuer, as in effect immediately prior to the Merger, remained as the articles of incorporation and bylaws of the Issuer.

Upon the closing of the Merger, the Shares that previously traded under the ticker symbol “NMRX”, ceased trading on, and are being delisted from, the Nasdaq Stock Market LLC. In addition, the Shares will be deregistered under the Exchange Act.

As stated above, the foregoing descriptions of the Merger Agreement, the Voting Agreements and the transactions contemplated thereby are not intended to be complete and are qualified in their entirety by reference to the Merger Agreement and the Voting Agreements, copies of which are listed as Exhibits hereto and are incorporated herein by reference.

Item 5.

Item 5 of the Original 13D is hereby amended and restated in its entirety as follows:
