Full Year Net Income Increases 191% to $8.1 Million, or $0.68 in EPS

Bridgeview, IL, March 11th, 2013 — 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 fourth quarter and full year 2012 results.

Fourth Quarter and Full Year 2012 Financial Highlights:

Chairman and Chief Executive Officer, David Langevin, commented, “2012 was an exciting year of growth for Manitex, despite the continuing challenges of a weak global economy. We turned in record performance for revenues, EPS, EBITDA, backlog and other key metrics, due to solid execution of our business plan across the board. Our investment in new products has already assisted in our growth, with products we’ve developed and launched in the last three years now accounting for nearly 25% of our annual revenues, and we believe these will help drive us further in the future.”

2012 revenues of $205.2 million increased $63.0 million or 44% from 2011 resulting from production increases at several facilities implemented in response to the higher levels of demand experienced over the past twelve months. Although the general economic environment in our N. American and European markets was one of limited or zero growth, our products targeted to the energy and power line distribution sectors benefited from the higher levels of activity in these sectors as well as from increased market penetration. All operations experienced higher growth, but higher capacity and specialized boom trucks drove almost 70% of the year over year revenue increase, with specialized trailers and other material handling equipment also strongly contributing. In the fourth quarter of 2012, revenues were $56.5 million, an increase year over year of $20.0 million or 55% and a sequential quarter increase of $3.1 million or 6%. Boom truck products accounted for over 80% of the increase, complemented by the equipment distribution segment where both new and used equipment revenues improved.

Net income for 2012 of $8.1 million or $0.68 per share was an increase of $5.3 million, (191%) or $0.44. per share, over 2011. A $63 million, (44%), year over year improvement in revenue resulted in a gross profit increase of $11.2 million which offset additional operating expenses and other expense of $3.4 million and $0.2 million respectively, and increased tax expense of $2.4 million. Gross profit of $40.5 million was equal to 19.7% of sales, a slight reduction from the 20.6% gross profit percent for 2011, principally a result of a lower percentage of higher margin parts sales in total revenues, despite an increase in part sales dollar value, due to the significant increase in new unit sales year over year. Excluding the $1.2 million of unusual legal settlement costs incurred in 2011, the year over year increase in operating expense was $4.5 million. Increased R&D expenditures accounted for $0.9 million of the increase as new product development activities were initiated to bring new products to market in the year and in 2013. Increased selling expenses of approximately $2.0 million were incurred from an expansion in the sales organization, commissions and other selling related costs, with employee related costs from additional staff and performance related expense and professional fees for Sarbanes Oxley comprising the balance. In total SG&A as a percent of revenue declined in 2012 to 11.5% from 14.0% in 2011.

Net income for the fourth quarter of 2012 was $2.0 million or $0.16 per share compared to $0.3 million and $0.03 per share for the fourth quarter of 2011, an increase in net income of $1.7 million or 597%. A sales improvement of $20.0 million (55%) resulted in a gross profit increase of $2.8 million which offset additional operating expenses of $0.4 million, other expense of $0.1 million and an increase in tax of $0.6 million. Gross profit was equal to 18.3% of sales, a reduction from 2011 quarter four of 220 basis points resulting from the lower mix of part sales in revenue and lower production efficiencies in the period from a new product launch and the holiday period. SG&A expense increased $1.5 million from increased sales expense, employee related expense including incentive compensation and professional fees from the additional compliance requirements of Sarbanes Oxley for the Company as an accelerated filer. SG&A expense for the quarter was 11.5% of sales, an improvement of 210 basis points from the fourth quarter of 2011.

Andrew Rooke, Manitex International President and Chief Operating Officer, commented, “2012 results were very pleasing on many fronts and position us well for further growth in 2013. With the increase in end user demand in our served markets throughout the year, we successfully implemented production increases at several facilities, reported revenues for quarter four 2012 at the highest quarterly level ever achieved by the Company and finished the year with a backlog at December 31 2012 of $130 million. During 2012 we increased our strategic investments in R&D for new products across our product portfolio that should drive profitable growth in 2013 and beyond. Our balance sheet at December 31 2012 was also strong, as reflected in our current ratio of 2.4, our net debt to capitalization ratio of 44.2%, improved from 47.4% at December 31, 2011, and our interest coverage ratio of 7.3 times. With EBITDA of $18.0 million for the full year, our debt to EBITDA ratio of 2.7 times also positions us well to continue our growth objectives.”

Outlook

Mr. Langevin continued, “While our expectations are for a continuation of modest economic improvement, but with pronounced weakness in Europe, we believe our growth will continue to be driven by selectively adding products and Companies that fit strategically with our Company. Our current business model has us positioned with approximately 50% of our sales going into the energy area and the other 50% sold into the general commercial markets. We believe this puts our Company and our shareholders in the best position to realize above average returns for 2013 and beyond. To that end, we’ve established a 2015 sales target of $350 million, excluding any acquisitions, with earnings and cash flow consistent with our current run rates.”

Supplemental Information

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 three or twelve month period ended December 31, 2012, unless otherwise indicated.

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 twelve month periods ended December 31, 2012 and 2011 is included with this press release below and with the Company’s related Form 8-K.

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

Backlog

Backlog is defined as purchase 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.

Interest Cover is calculated by dividing EBITDA (Earnings before interest, tax, depreciation and amortization) for the trailing twelve month period (January 1, 2012 to December 31, 2012) by interest expense as reported in the Consolidated Statement of Income for the same period.

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 Twelve Months EBITDA is calculated by adding the reported EBITDA for the past 4 quarters.

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
