Manitex to Acquire Sabre Manufacturing, LLC for $14 Million

Bridgeview, IL, August 7th, 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 second quarter 2013 results.

Second Quarter 2013 Financial Highlights:

Acquisition of Sabre Manufacturing, LLC:

Chairman and Chief Executive Officer, David Langevin commented “The record sales and profits we recorded in the second quarter results demonstrates continued execution of our niche product strategy. The global economic environment, as has been widely reported remains subdued, and while we are cautious we believe our businesses will continue to perform on a solid basis in this challenging economic landscape. The primary driver of our growth remains our crane business. And as we recently reported, we believe that our new 70 ton crane

product will have a significant impact for us in the future. We would also like to point out the significance of the $37 million Navy contract award which we recently announced which will also provide further growth for us in 2014. Finally, in the second quarter, our cost structure, margins and EBITDA ratios all returned to more normal levels when compared to the first quarter. With this cost concentration and a steady improvement in economics along with the potential benefit from the acquisition of Sabre which we announced today, we should turn in good results for the year and put us on sound footing going into 2014.”

Second quarter 2013 revenues of $62.6 million increased $10.1 million or 19.2% from the second quarter of 2012 resulting primarily from production increases at the Manitex crane facility and increased sales for port-related equipment from CVS, partially offset by lower revenues from other material handling operations and equipment distribution. Cranes with capacities greater than 45 ton increased as a proportion of total revenues contributing approximately $5 million of the total increase. The lower margin, lower capacity boom trucks and chassis sales also increased approximately $3 million in response to improved commercial construction activity, which utilizes the lower capacity, less specialized cranes. Parts sales as a percentage of revenue for the quarter were approximately 18% lower than the prior year quarter due to the increase in new product revenues, but were also marginally reduced on a dollar basis. On a sequential quarter basis, revenues increased 5%, with a 12% increase in sales of cranes, on a number of units basis, although this was partially offset by reduced material handling and equipment distribution sales.

Gross profit of $12.3 million was equal to 19.6% of sales, compared to $10.8 million or 20.5% for the second quarter of 2012 and $10.2 million or 17.2% in the first quarter of 2013. The year-over-year reduction in gross margin percent was generated by an increase in the mix of lower capacity cranes and chassis, and a lower percentage of higher margin parts sales. Parts sales are anticipated to return in line with their historical levels over time as the recent rapid increase in new equipment sales become increasingly deployed and utilized. The 240 basis point sequential improvement to more normalized levels was generated by improved manufacturing efficiencies over the prior quarter as newer products became better assimilated into manufacturing as well as a benefit from improved volume and product mix.

Net income for the second quarter of 2013 of $2.7 million or $0.22 in earnings per share was an increase of $0.3 million, (15%) or $0.02 per share, over the second quarter of 2012. A $10.1 million improvement in revenue compared to the second quarter of 2012 resulted in a gross profit increase of $1.5 million which was offset by additional operating expenses, other expense and tax of $1.2 million. Operating expense was $1.1 million higher in the second quarter of 2013 of which increased selling expenses of $0.6 million were incurred from an expansion in the sales organization, commissions and other selling related costs, with employee related costs and incentive compensation accounting for approximately $0.3 million.

Andrew Rooke, Manitex International President and Chief Operating Officer, commented, “We again achieved record sales revenues for the quarter, showing increases on a year ago and sequential quarter basis, with crane products leading the way. Our production increases combined with a softening of demand from energy markets compared to the same period a year ago and continued relative weakness in material handling contributed to a modest reduction in backlog, which was $97 million at the end of the quarter, and still remains healthy. Gross margin at 19.6% for the quarter returned to more normalized levels as the recent product introductions became fully integrated into the supply chain and production process, and we achieved improved manufacturing volume in the Manitex crane facility. The lower percentage of parts sales due to higher new equipment sales still had a negative effect in the quarter, but this also remains a future opportunity as parts sales start to reflect the higher volume of equipment being deployed. Our commitment to cost control and higher efficiency remains a key objective, as evidenced in our SG&A, which as a percentage of sales, remained steady with the second quarter of 2012 at 11.3%. However, it has been reduced by 100 basis points to 10.8% for the six months ended June 30, 2013 compared to 11.8% for the corresponding period in 2012. Our balance sheet position remains strong, with our debt to trailing twelve month EBITDA ratio of 2.8 times and interest coverage of 7.5 times, both ratios remaining relatively constant since December 31, 2012.”

Outlook

Mr. Langevin continued, “The quarterly and year to date results were solid, and we continue to work to develop and acquire niche products which serve industries where we believe there will be superior growth and where we will have the opportunity to grow at levels beyond anyone in the marketplace. We look forward to welcoming to the Manitex Group a Company that we believe fits these criteria in Sabre Manufacturing. Sabre is a leading specialized equipment provider with a reputation for high quality and innovation serving a market of over $1 billion annually.

Our expectations, absent any significant change in the global economic conditions and excluding the additional benefit we may receive from Sabre, are for second half sales in line with the first. This would suggest another record year for revenues, EBITDA and earnings per share. We also continue to pursue further growth of our revenue base as well as an increase in our profitability through development of new products and opportunistic acquisitions,” concluded Mr. Langevin.

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 month period ended June 30, 2013, 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 six month periods ended June 30, 2013 and 2012 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 (July 1, 2012 to June 30, 2013) 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
