EXPLANATORY NOTE

Analogic Corporation (the “Company”, “we”, or “our”) is filing this Amendment No. 1 to our Quarterly Report on Form 10-Q for the quarter ended October 31, 2013, as originally filed with the Securities and Exchange Commission (the “SEC”) on December 10, 2013 for the sole purpose of amending and restating Item 4. Controls and Procedures. As originally filed, Item 4 incorrectly stated the nature of the assessment performed in connection with the quarter. Item 4 has been amended and restated to correctly reflect management’s conclusions regarding the effectiveness of our disclosure controls and procedures as of October 31, 2013 and certain changes in our internal control over financial reporting. Except as amended below in connection with Item 4, there are no other amendments to the Form 10-Q as originally filed. This Form 10-Q/A includes Exhibits 31.1, 31.2, 32.1 and 32.2, certifications by the company’s principal executive officer and principal financial officer as required by Rule 12b-15.

Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures as of October 31, 2013. The term “disclosure controls and procedures”, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by the 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 officer and principal financial officer, as appropriate, to allow timely decisions to be made regarding required disclosure. It should be noted that any system of controls and procedures, however well designed and operated, can provide only reasonable, and not absolute, assurance that the objectives of the system are met and that 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 October 31, 2013, our principal executive officer and principal financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in internal control over financial reporting

In 2013, we completed the installation and integration of a new enterprise resource planning system for certain of our locations. The new system upgraded our overall information system capabilities, including our financial reporting systems, and supports improved business processes and enhanced internal controls. We expect to continue with the installation and integration of the new system across additional locations. There were no other changes in our internal control over financial reporting during the three months ended October 31, 2013 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

The exhibits listed on the Exhibit Index immediately preceding such exhibits, which is incorporated herein by reference, are filed or furnished as part of this quarterly report on Form 10-Q.
