PEABODY, Mass. (September 20, 2011) – Analogic Corporation (Nasdaq:ALOG), a leading provider of medical imaging and aviation security technology, today announced results for its fourth quarter and fiscal year ended July 31, 2011.

Highlights during the fourth quarter included:

Highlights for fiscal year 2011 included:

Revenues for the fourth fiscal quarter ended July 31, 2011, were $135.3 million, compared with third quarter revenues of $117.2 million and the prior fiscal year’s fourth quarter revenues of $115.0 million. GAAP net income for the fourth quarter of fiscal 2011 was $5.6 million, or $0.45 per diluted share, compared with income of $4.3 million, or $0.35 per diluted share, in the third quarter of fiscal 2011 and $7.1 million, or $0.56 per diluted share, for the prior year’s fourth quarter. Included in net income for the fourth quarter of fiscal 2011 was $3.6 million, or $0.20 per diluted share, for restructuring charges primarily associated with the consolidation of our ultrasound business and streamlining of our overall operations.

Non-GAAP net income for the fourth quarter was $10.3 million, or $0.83 per diluted share, compared with $6.7 million, or $0.54 per diluted share, in the third quarter of fiscal 2011, and $8.8 million, or $0.69 per diluted share, for the prior year’s fourth quarter. A reconciliation of reported to non-GAAP results is included as an attachment to this press release.

For fiscal 2011, revenues totaled $473.6 million, compared with revenues of $414.8 million in fiscal 2010, up 14%. GAAP net income for fiscal 2011 totaled $17.8 million, or $1.42 per diluted share, as compared with $15.6 million, or $1.23 per diluted share, for fiscal 2010. Non-GAAP net income for fiscal 2011 totaled $29.5 million, or $2.35 per diluted share, as compared with $21.7 million, or $1.72 per diluted share, for fiscal 2010.

Jim Green, president and CEO, commented, “I am very pleased with our strong performance in the fourth fiscal quarter, as we achieved the sixth consecutive quarter of double-digit, year-over-year, revenue growth, and achieved 10% non-GAAP operating margins driven by strong demand for our medical imaging and security products. We continue to see growth in our Medical Imaging business across our product lines on growing customer demand. Our Ultrasound business saw solid growth and our Security business had an exceptional quarter.”

“Fiscal year 2011 was a record year in revenues and we expect to stay on a growth trajectory,” Green continued. “Our business is on solid footing as we completed the realignment of the business around our three fundamental pillars of Medical Imaging, Ultrasound, and Security in the fourth quarter and we are confident that we will achieve our previously stated financial goal of double-digit non-GAAP operating margin for fiscal 2012.”

Segment Revenues

Revenue from our Medical Imaging segment was $89.3 million for the fourth quarter of fiscal 2011, up $6.3 million from the third quarter and up $16.0 million over the prior year’s fourth quarter. Revenue was up sequentially and year over year driven by greater overall demand for our medical imaging products.

Our Ultrasound segment revenue was $26.8 million for the fourth quarter of fiscal 2011, up $2.8 million from the third quarter and up $3.8 million over the prior year. Revenue was up sequentially due to typical seasonality as well as addressing product supply constraints from the third quarter related to our manufacturing transition. Revenue grew year over year due to stronger demand for our Flex Focus™ ultrasound systems.

Security Technology segment revenue was $19.2 million for the fourth quarter of fiscal 2011, up $9.0 million from the third quarter and up $0.6 million from a year earlier. Revenue was up sequentially due mainly to the timing of shipments under bridge orders from our OEM customer as well as higher engineering revenues in the quarter. Revenues continue to remain variable under these bridge orders due to the Transportation Security Administration’s deployment of a new procurement process.

Quarterly Cash Dividend

Analogic’s Board of Directors, on September 15, 2011, declared a $0.10 cash dividend for each common share for its fourth fiscal quarter ended July 31, 2011. The cash dividend will be payable on October 18, 2011, to shareholders of record on October 5, 2011.

CONSOLIDATED STATEMENTS OF OPERATIONS

(Unaudited)

UNAUDITED SUPPLEMENTAL INFORMATION - RECONCILIATION OF REPORTED (GAAP) TO NON-GAAP MEASURES

We provide non-GAAP gross profit, operating expenses, income from operations, income from continuing operations, diluted earnings per share from continuing operations, net income and diluted net income per share as supplemental measures to reported results regarding our operational performance. These financial measures exclude the impact of certain items and, therefore, have not been calculated in accordance with GAAP. The adjustments to these financial measures, and the basis for such adjustments, are outlined below:

Share-Based Compensation Expense

We incur expense related to share-based compensation included in the reported presentation of cost of sales, research and development, selling and marketing, general and administrative expense. Although share-based compensation is an expense and viewed as a form of compensation, these expenses vary in amount from period to period, and are affected by market forces that are difficult to predict and are not within our control, such as the market price and volatility of our shares, risk-free interest rates, and the expected term and forfeiture rates of the awards. Share-based compensation expense is calculated as of the grant date of each share-based award, and generally cannot be changed or influenced by management after the grant date. Our management team believes that exclusion of these expenses allows comparisons of operating results that are consistent between periods and allows comparisons of our operating results to those of other companies that disclose non-GAAP financial measures that exclude share-based compensation.

Acquisition Related Gains and Expenses

We incur amortization of intangibles and other expenses related to acquisitions we have made in recent years. The intangible assets are valued at the time of acquisition, are then amortized over a period of several years after the acquisition and generally cannot be changed after the acquisition. During fiscal year 2011, our results included accounting items related to an acquisition of an OEM ultrasound transducer and probe product line. The acquisition accounting items included a bargain purchase gain (i.e. the acquired assets exceeded the amount to be paid for the acquisition) of $1,042,000 recorded in general and administrative expenses within operating income. We believe the exclusion of this gain and acquisition related expenses allow comparisons of operating results that are consistent over time for both our newly acquired and long-held businesses.

Restructuring

During the three months ended July 31, 2011, we initiated a plan to reduce our work force by 51 employees worldwide as we continue to streamline our overall operations. The total cost, including severance and personnel related costs, was $3,585,000 and was recorded as an operating expense during the three months ended July 31, 2011. During the three months ended October 31, 2010, we initiated a plan to reduce our work force by 104 employees worldwide as we continue to streamline our operations and consolidate our Denmark and Canton, Mass. manufacturing operations into our existing U.S. facilities. The total cost, including severance and personnel related costs, was $3,562,000 and was recorded as an operating expense during the three months ended October 31, 2010. We adjusted restructuring charges by ($134,000) and $53,000 in the three months ended January 31, 2011 and July 31, 2011, respectively. During the three months ended January 31, 2010, we reduced our work force by 17 employees worldwide. The total cost, including severance and personnel related costs, was $764,000 and was recorded as an operating expense during the three months ended January 31, 2010.

Taxes

For purposes of calculating non-GAAP net income and non-GAAP diluted earnings per share, we adjust the provision (benefit) for income taxes to tax effect the non-GAAP adjustments described above as they have a significant impact on our income tax provision (benefit). In addition, from time-to-time, we recognize certain non-recurring tax adjustments.

We exclude the above-described expenses, their related tax impact and other non-recurring tax benefits in evaluating short-term and long-term operating trends in our operations, and allocating resources to various initiatives and operational requirements. We believe that these non-GAAP financial adjustments are useful to investors because they allow investors to evaluate the effectiveness of the methodology and information used by management in its financial and operational decision-making.

These non-GAAP financial measures have not been prepared in accordance with GAAP, and should not be considered in isolation or as a substitute for financial information provided in accordance with GAAP. Further, these non-GAAP financial measures may not be computed in the same manner as similarly titled measures used by other companies.

The following table reconciles the non-GAAP financial measures to their most directly comparable GAAP financial measures.
