Manitex International, Inc. Reports Second Quarter 2011 Results

Achieves 90% Increase in Second Quarter Revenue and EPS of $0.09

Year-to-date Backlog Grows 27% to $51 Million

Bridgeview, IL, August 10, 2011 — Manitex International, Inc. (Nasdaq: MNTX), a leading provider of engineered lifting solutions including boom truck and rough terrain cranes, rough terrain forklifts, special mission oriented vehicles, container handling equipment and specialized engineered trailers, today announced second quarter 2011 revenues of $37.1 million representing a 90% year-over-year increase. Net income for the second quarter of 2011 was $1.0 million or $0.09 per share compared to $0.2 million or $0.02 per share for the second quarter of 2010.

Second Quarter 2011 Financial Highlights:

Chairman and Chief Executive Officer, David Langevin, commented, “We continued to show progress as demonstrated throughout our second quarter results. New bookings across our business units resulted in healthy backlog growth, and strong year-over-year increases in sales, EBITDA, and earnings per share. Other equally important measures of our success in the quarter included the finalization of the CVS Ferrari acquisition, and the expansion and extension of our credit facility, which we believe will be key strategic drivers of our future growth. We’re excited about the progress we continue to make and we believe we are well-positioned for a strong second half. Nevertheless, we are very aware that in these uncertain economic times we must be very cognizant of controlling our costs and remain vigilant in this regard, as we have done in the past.”

Second quarter 2011 net revenues of $37.1 million, including approximately $8 million of sales from the Italian CVS Ferrari operations, increased $17.6 million or 90% over the second quarter of 2010. Excluding the impact of new operations, organic revenue growth was 39%. Revenue increases were obtained in both of our operating segments, with Lifting Equipment increasing 81% and Equipment Distribution increasing 254%.

sales increased approximately 80% and continue to reflect strong demand for larger tonnage product from the specialty energy and utility markets, in both the US and internationally. Material handling products benefited from another strong quarter from the CVS Ferrari container handling business and improved demand in the specialized trailer market which helped offset weaker demand in the higher margin military and specialized governmental products. The increase in equipment distribution revenues was driven by our used equipment sales program which we began in June 2010 and increased parts sales and service activity. On a sequential quarter basis, total revenues increased 17% largely due to increased sales from the crane operations.

Gross profit of $7.5 million was a $2.9 million increase above the second quarter of 2010 driven by increased sales volume. Gross profit margin for the quarter was 20.2% compared with 23.6% for the second quarter of 2010 with the reduction resulting from lower margin product mix in sales in the material handling and distribution businesses and increased material costs. Compared to the second quarter of 2010, in material handling, there was a decrease in shipments of higher margin military and governmental units while in distribution, the increase in revenues was principally from lower margin used equipment and service sales. Gross profit margin of 20.2% in the second quarter 2011 was consistent with the 20.4% achieved in the first quarter 2011, reflecting a similar mix in sales together with material prices that are higher than the comparable 2010 period but relatively stable on a sequential quarter basis.

Operating expenses for the second quarter 2011 were $5.2 million and included expenses of $0.9 million relating to expenditures at the CVS Ferrari operations and new operations started in 2010. This compared to $3.7 million in the second quarter of 2010. R&D expenses increased $0.1 million from new projects commenced in the year. SG&A expense excluding the cost of the new operations, increased $0.6 million, of which $0.3 million was related to increased selling expense and $0.3 million related to other increases including personnel costs from the reinstatement of salaries reduced during the 2008 / 09 downturn and a limited increase in headcount. SG&A expense for the second quarter 2011 was equivalent to 13.1% of sales compared to 16.9% and 15.4% for the second quarter of 2010 and the first quarter of 2011, respectively.

Andrew Rooke, Manitex International President and Chief Operating Officer commented, “Operational results, as reflected in EPS of $0.09 per share for the quarter, were driven by the strength of our boom truck crane operations which continue to benefit from demand in the energy and utility sectors in the US and internationally. Our other products benefited from the improved market conditions, although the economic recovery, particularly in the US, remains limited to certain sectors. Our non US sales continue to be a strong factor in overall performance with these being approximately 41% of our total year to date sales. In container handling, we received another solid performance from CVS Ferrari and with the completion of the asset acquisition on July 1^st we believe we have improved opportunities for commercial success in this growing global business. Our gross profit margin in the quarter and this year has been pressured by both unfavorable sales mix, with lower military sales, and higher materials cost compared to the comparable 2010 period. However, we are working with the supply chain to mitigate or avoid these cost increases and have implemented selective price increases to offset some of this adverse impact.”

Mr. Rooke continued, “Working capital remains a key focus as our activity levels increase at different rates across the organization and we manage this year’s 66%, year over year growth. In relation to this, our key working capital measure, the ratio of operating working capital to annualized last quarter’s sales improved to 30.4% at June 30, 2011, compared to 41.4% at June 30, 2010. The management of our credit facilities is also a critical aspect of our operational activity and recently we were pleased to announce our four year renewal of these credit facilities with increased borrowing ability and reduced interest rates which ensures we have the required resources to support our growth plans.”

Outlook

Mr. Langevin concluded, “With our current backlog of approximately $51 million combined with normalized parts sales for the rest of the year, and assuming no dramatic changes in the overall economic environment and that we receive material and components on a timely basis, we would expect sales for 2011 to be approximately $140 million, equivalent to an increase of 46% from 2010.”

Supplemental Information

Non-GAAP Financial Measures

This press release includes the following non-GAAP financial measure: “EBITDA” (earnings before interest, tax, depreciation and amortization). This non-GAAP term, as defined by the Company, may not be comparable to similarly titled measures used by other companies. EBITDA is not a measure of financial performance under generally accepted accounting principles. Items excluded from EBITDA are significant components in understanding and assessing financial performance. EBITDA should not be considered in isolation or as a substitute for net earnings, operating income and other consolidated earnings data prepared in accordance with GAAP or as a measure of our profitability. A reconciliation of net income to EBITDA is provided below.

The Company’s management believes that EBITDA and EBITDA as a percentage of sales represent key operating metrics for its business. Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) is a key indicator used by management to evaluate operating performance. While EBITDA is not intended to replace any presentation included in our consolidated financial statements under generally accepted accounting principles (GAAP) and should not be considered an alternative to operating performance or an alternative to cash flow as a measure of liquidity, we believe this measure is useful to investors in assessing our capital expenditure and working capital requirements. This calculation may differ in method of calculation from similarly titled measures used by other companies. A reconciliation of EBITDA to GAAP financial measures for the three and six month periods ended June 30th, 2011 and 2010 is included with this press release below and with the Company’s related Form 8-K.

Reconciliation of GAAP Net Income from Continuing Operations to Earnings Before Interest, Taxes, Depreciation and Amortization (EBITDA) from Continuing Operations (in thousands)

In an effort to provide investors with additional information regarding the Company’s results, Manitex International refers to various non-GAAP (U.S. generally accepted accounting principles) financial measures which management believes provides useful information to investors. These measures may not be comparable to similarly titled measures being disclosed by other companies. In addition, the Company believes that non-GAAP financial measures should be considered in addition to, and not in lieu of, GAAP financial measures.

Manitex International believes that this information is useful to understanding its operating results and the ongoing performance of its underlying businesses. Management of Manitex International uses these non–GAAP financial measures to establish internal budgets and targets and to evaluate the Company’s financial performance against such budgets and targets.

The amounts described below are unaudited, are reported in thousands of U.S. dollars, and are as of or for the period ended June 30, 2011, unless otherwise indicated.

Backlog

Backlog is defined as firm orders that have been received by the Company. The disclosure of backlog aids in the analysis the Company’s customers’ demand for product, as well as the ability of the Company to meet that demand. Backlog is not necessarily indicative of sales to be recognized in a specified future period.

Current Ratio is calculated by dividing current assets by current liabilities.

Days Sales Outstanding, (DSO), is calculated by taking the sum of net trade and related party receivables divided by annualized sales per day (sales for the quarter, multiplied by 4, and the sum divided by 365).

Days Payables Outstanding, (DPO), is calculated by taking the sum of net trade and related party payables divided by annualized cost of sales per day (cost of goods sold for the quarter, multiplied by 4, and the sum divided by 365).

Debt is calculated using the Condensed Consolidated Balance Sheet amounts for current and long term portion of long term debt, capital lease obligations, notes payable and lines of credit.

Inventory turns are calculated by multiplying cost of goods sold for the referenced three month period by 4 and dividing that figure by inventory as at the referenced period.

Manufacturing Expenses include manufacturing wages, salaries, fixed and variable overhead costs.

Operating Working Capital is calculated using the Consolidated Balance Sheet amounts for Trade receivables (net of allowance) plus other receivables, plus inventories, less Accounts payable. The Company considers excessive working capital as an inefficient use of resources, and seeks to minimize the level of investment without adversely impacting the ongoing operations of the business.

Trailing Three Month Annualized Net Sales is calculated using the net sales for quarter, multiplied by four.

Working capital is calculated as total current assets less total current liabilities.
