Manitex International, Inc. Reports Fourth Quarter and Full Year 2014 Results

Reports Record Annual Net Revenues of $264.1 Million

New Acquisitions of PM Group and ASV Advance Manitex into 2015

Bridgeview, IL, March 5, 2015 — Manitex International, Inc. (Nasdaq: MNTX), a leading international provider of cranes and specialized material and container handling equipment, today announced fourth quarter and full year 2014 results.

Full Year 2014 Financial Highlights:

Fourth Quarter 2014 Financial Highlights:

Transactions:

Chairman and Chief Executive Officer, David Langevin, commented, “While we achieved record net sales and maintained our track record of profitability and ebitda generation even in a difficult equipment operating environment, our Company’s biggest achievements in the year were the transactions we consummated, which have positioned us for continued long term shareholder growth. ASV has an excellent track record in serving the housing industry and we believe that there is substantial value that our shareholders will recognize from ASV’s contribution, with margins that are higher than ours and exposure to the growing construction market. Further, the PM Group brings to Manitex shareholders a similar opportunity with its product extension in our most profitable crane category and a restructured balance sheet. We welcome the excellent and devoted PM and ASV employees to the Manitex family. The addition of PM and ASV, along with the many other Manitex product brands further establishes Manitex as a premier specialized niche equipment provider serving a broad range of end markets.”

2014 revenues increased $19.0 million or 7.8% from 2013 to $264.1 million, including $2.3 million from the ASV JV that commenced operations in mid-December of 2014. Excluding ASV, 2014 revenues increased 6.8%, driven substantially by growth in container handling equipment, material handling equipment and equipment distribution revenues that grew year over year by 20%, 14% and 24% respectively. Crane revenues decreased in line with the reduction in our largest market, the boom and truck crane market that was down almost 8% year over year and shipments of larger tonnage cranes being down almost 19% reflecting a softer oil and gas market. Our CVS container handling products benefited from a modest strengthening in Europe as well as expansion and improved distribution into overseas markets.

In the fourth quarter of 2014, revenues were $66.9 million, including $2.3 million of revenues from the previously referenced ASV JV, and were an increase year over year of $1.5 million or 2.3%. Container handling increased approximately 2% year over year but both cranes and material handling equipment showed year over year reductions of three to four percent. Partially offsetting the reduction in the material handling equipment was an increase in shipments of military material handling equipment. Equipment distribution sales were up almost 70% from a relatively low level in the fourth quarter of 2013.

Adjusted net income for 2014 of $8.8 million or $0.63 per share was a decrease of $1.4 million, or $0.17 per share, over 2013. A $19.0 million year over year improvement in revenues resulted in a gross profit increase of $1.8 million which partially offset additional operating expenses of $0.1 million, operating expenses from acquired businesses of $2.9 million, and increased tax expense of $0.2 million. Adjusted net income excludes $2.5 million pre-tax of acquisition related and other costs. Included in these costs is approximately $0.5 million of costs related to the PM Group acquisition that was completed in January of 2015. Gross profit of $48.3 million was equal to 18.3% of sales, a slight reduction from the 19.0% gross profit percent for 2013, principally a result of changes in product mix in sales, particularly from the reduction in higher tonnage crane sales. The increase in operating expense was principally increased sales expense from expanding and reorganizing the sales organization offsetting reduced performance compensation and reduced R&D expenses as a number of new products were now launched into production. In total, after adjustments for deal and other related costs SG&A as a percent of revenue was 11.1% compared to 10.6% in 2013.

Excluding $2.5 million pretax of acquisition related and other costs, adjusted net income for the fourth quarter of 2014 was $2.2 million or $0.16 per share compared to net income of $3.0 million and $0.22 per share for the fourth quarter of 2013. A sales improvement of $1.5 million resulted in a gross profit decrease of $0.1 million from the impact of a change in the sales mix between the two periods. Additional operating expenses of $0.2 million, operating expenses from acquired businesses of $0.6 million, and reduced tax expense of $0.1 million resulted in adjusted net income for the period of $2.2 million. Gross profit was equal to 18.9% of sales, an increase from 2014 quarter three of 240 basis points and a decrease from 2013 quarter four of 60 basis points, resulting from mix in sales. Operating expenses excluding the impact of newly acquired businesses increased $0.2 million compared to the fourth quarter of 2013 largely from increased selling expenses. In total, adjusted SG&A in quarter four of 2014 was 11.8% of sales compared to 10.6% in the same period of 2013.

Andrew Rooke, Manitex International President and Chief Operating Officer, commented, “2014 was another year of significant progress for the Company, in an environment that continued to be challenging, particularly in the second half of the year, and where our principal market, boom and truck cranes, was adversely impacted by a slower oil and gas sector and was down approximately 8% year over year. It would not be an overstatement to say that the acquisition of the PM Group and the ASV joint venture with Terex made 2014 a transformational year for Manitex. Consistent with our legacy, we found opportunities to significantly diversify our market and geographic exposures. Operationally, the fourth quarter was an improvement from the third, as our mix of sales improved benefiting gross profit percent which came in at 18.9%, and we started with ASV operations in the last two weeks of the year.

Mr. Rooke continued, “The year was behind the levels of 2013 in terms of our profitability, but we are pleased with our long-term business position and we believe that the underlying fundamentals of our strategy are sound. In closing the two large transactions, PM and ASV, we incurred some additional debt and issued some shares. On the debt side, our projected average debt servicing cost is approximately 6%, which is very favorable for a company our size. That said, we’re conscious of this debt and our plan is to pay much of this down with cash flow we generate this year and beyond. Additional acquisition related costs are expected to be charged in the first quarter of 2015, approximating $1.3 million, and beyond that we would expect cleaner quarterly comparisons going forward.”

Mr. Langevin concluded, “We believe that 2015 will be another challenging year for the equipment sector in general although we will continue to work hard to achieve our long term growth targets. We are implementing cost saving actions that could save us approximately $4 million this year and approximately $15 million over the next three years. These benefits will assist us in margin protection and we believe we will realize further benefits from production and integration efficiencies as well as new sales opportunities resulting from the PM and ASV additions. We’re optimistic that the line of knuckle boom cranes we added form the PM Group could be a very meaningful contributor to orders and to our financial performance in 2015 and beyond, and we believe that ASV will be a significant contributor to long term value enhancement for our shareholders.”

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 non-GAAP 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 both GAAP and 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 and twelve month periods ended December 31, 2014, unless otherwise indicated.

Non-GAAP Financial Measures

This press release includes the following non-GAAP financial measures: “Adjusted EBITDA” (earnings before interest, tax, foreign exchange transaction gain / losses, other income / expense acquisition related expense and other exceptional costs and depreciation and amortization) and Adjusted Net Income. These non-GAAP terms, as defined by the Company, may not be comparable to similarly titled measures used by other companies. Neither Adjusted Net Income nor Adjusted EBITDA are a measure of financial performance under generally accepted accounting principles. Items excluded from Adjusted EBITDA and Adjusted Net Income are significant components in understanding and assessing financial performance. Adjusted EBITDA and Adjusted Net Income 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 Adjusted EBITDA and Adjusted Net Income is provided below.

The Company’s management believes that Adjusted EBITDA and Adjusted EBITDA as a percentage of sales and Adjusted Net Income represent key operating metrics for its business. Adjusted Earnings Before Interest, Taxes, foreign exchange transaction gain / losses, other income / expense, acquisition related expense and other exceptional costs and Depreciation and Amortization (Adjusted EBITDA) and Adjusted Net Income, GAAP net income adjusted for acquisition and certain other one off items are a key indicator used by management to evaluate operating performance. While Adjusted EBITDA and Adjusted Net Income are 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 these measures are useful to investors in assessing our operating results, capital expenditure and working capital requirements and the ongoing performance of its underlying businesses. These calculations may differ in method of calculation from similarly titled measures used by other companies. A reconciliation of Adjusted EBITDA and Adjusted Net Income to GAAP financial measures for the three and twelve month periods ended December 31, 2014 and 2013 is included with this press release below and with the Company’s related Form 8-K.

Acquisition of 51% of ASV Inc.

On December 19, 2014, the Company acquired 51% of A.S.V., Inc. from Terex Corporation (“Terex”). Subsequent to the acquisition date ASV was converted to an LLC and its name was changed to A.S.V., LLC (ASV). ASV located in Grand Rapids, Minnesota manufactures a line of high quality compact rubber tracked and skid steer loaders. The ASV products will be distributed through the Terex distribution channels as well as through Manitex and other independent dealers. The products are used in the site clearing, general construction, forestry, golf course maintenance and landscaping industries, with general construction being the largest market.

ASV’s financial results are included in the Company’s consolidated results beginning on December 20, 2014.

Acquisition and other expense

After tax expense and per share amounts (Adjusted Net Income) are calculated using pre-tax amounts, applying a tax rate based on jurisdictional rates to arrive at an after-tax amount. This number is divided by the weighted average diluted shares to provide the impact on earnings per share. The company assesses the impact of these items because when discussing earnings per share, the Company adjusts for items it believes are not reflective of operating activities in the periods.

There were no items adjusting Fourth Quarter 2013 or Full Year 2013

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. Debt to Adjusted EBITDA ratio is calculated by dividing total debt at the balance sheet date by trailing twelve month Adjusted EBITDA.

Interest Cover is calculated by dividing Adjusted EBITDA (Earnings before interest, tax, foreign exchange transaction gain / losses, other income / expense and depreciation and amortization) for the trailing twelve month period (January 1 to December 31) 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 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 Adjusted EBITDA is calculated by adding the reported Adjusted 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
