Spartan Motors Reports First Quarter 2017 Results

CHARLOTTE, Mich., May 4, 2017 - Spartan Motors, Inc. (NASDAQ: SPAR) (“Spartan” or the “Company”), a global leader in specialty chassis and vehicle design, manufacturing and assembly, today reported operating results for the first quarter ending March 31, 2017.

First Quarter 2017 Highlights

For the first quarter of 2017 compared to the first quarter of 2016:

“We are very pleased with the operating results achieved for the quarter. On an adjusted basis, this marks our fifth profitable quarter in a row,” said Daryl Adams, President and Chief Executive Officer. “Our solid performance was driven by the continued operational improvements we have made in labor and manufacturing productivity, as a result of implementing the Spartan Production System, lean manufacturing and continuous improvement initiatives.”

Fleet Vehicles and Services (FVS)

FVS segment sales decreased 9.1% to $53.9 million from $59.3 million. The revenue decline was primarily due to lower volume at vehicle up-fit centers.

Adjusted EBITDA decreased $0.3 million to $6.2 million, or 11.6% of sales, from $6.5 million, or 10.9% of sales, a year ago. Unfavorable mix resulted in the decrease in adjusted EBITDA compared to last year. Despite this decrease, EBITDA margin increased 70 basis points reflecting improved labor and manufacturing productivity.

The Segment backlog at March 31, 2017 totaled $114.0 million compared to $89.5 million at December 31, 2016.

Specialty Chassis & Vehicles (SCV)

SCV segment sales remained comparable at $33.0 million. Revenues were impacted by a defense order that did not reoccur in 2017.

Adjusted EBITDA decreased 3.9% to $1.5 million, or 4.7% of sales, from $1.6 million, or 4.8% of sales, a year ago, mainly due to a defense order that did not reoccur in 2017.

The Segment backlog at March 31, 2017 totaled $22.8 million compared to $20.1 million at December 31, 2016.

Emergency Response (ER)

ER segment sales increased $39.1 million to $80.2 million, or 95.1%, from $41.1 million. The Smeal acquisition contributed $35.2 million of the increase (excludes $5.5 million of Spartan inter-company chassis sales), offset by fewer shipments of complete fire apparatus and custom cab and chassis compared to a year ago, as the Company continues to focus on profitable sales.

Adjusted EBITDA improved $1.8 million, to a loss of $1.3 million from a loss of $3.1 million a year ago. The improvement was primarily the result of improved quality, increased labor efficiencies and manufacturing productivity.

The Segment backlog at March 31, 2017 totaled $214.5 million compared to $139.9 million at December 31, 2016, and reflects $78.6 million in backlog from Smeal Fire Apparatus.

Acquisition Update

As previously announced, the Company completed the acquisition of Smeal Fire Apparatus Co. (“Smeal”) and its subsidiaries effective January 1, 2017. Smeal, an industry-leading innovator and manufacturer of fire apparatus in North America, generated first quarter 2017 revenues of $35.2 million (excludes $5.5 million of Spartan inter-company chassis sales). Smeal is expected to generate approximately $105 million in sales, excluding inter-company shipments, during 2017.

The Company results for the 2017 first quarter include approximately $2.6 million, or $0.07 per share of acquisition and restructuring related adjustments and expenses.

“Our team has been working tirelessly and our Smeal integration efforts are running ahead of schedule and are already generating positive outcomes,” continued Adams. “Not only have we identified more synergistic opportunities than originally anticipated, we are also experiencing significantly increased interest and excitement in our expanded product portfolio from our dealers and customers. We are excited to share that not only do we have the right team in place to make these integration efforts successful, we’re also applying lessons learned and documenting the process required for future acquisitions. These developments further abbreviate the timeline needed to accelerate the turnaround of the Emergency Response business and it remains on track to return to profitability on an adjusted basis in 2017.”

Raising 2017 Guidance

“Our strong first quarter performance reflects the favorable impact of successfully implementing lean manufacturing, continuous improvement initiatives across all production facilities and the Smeal integration that is ahead of schedule,” said Rick Sohm, Chief Financial Officer of Spartan Motors. “Looking ahead to the remainder of the year, we expect to see continued year-over-year operational improvements and additional synergies realized from the Smeal integration, which gives us comfort in raising the 2017 guidance.”

Outlook for the full year 2017 is now expected to be as follows:

“The confidence you see from the Spartan team is undeniable. Not only have we made marked improvements toward the Emergency Response business’ turnaround and condensed its associated timeline, we’ve realized additional synergies and in short order have simultaneously managed to improve our base business. There is a drum beat driving this quarter-by-quarter profitability, and it’s not going to stop here. I am incredibly excited to share that confidence with our shareholder community in the form of increased guidance. The progress you see to date as we execute on the Smeal integration plan is only the beginning,” Adams concluded.

Reconciliation of Non-GAAP Financial Measures

This release contains Adjusted EBITDA (earnings before interest, taxes, depreciation and amortization), adjusted net income attributable to Spartan Motors, Inc., adjusted earnings per share, forecasted Adjusted EBITDA, and forecasted adjusted earnings per share, which are all Non-GAAP financial measures. Our management uses Adjusted EBITDA to evaluate the performance of and allocate resources to our segments. These non-GAAP measures are calculated by excluding items that we believe to be infrequent or not indicative of our operating performance. For the periods covered by this release such items consist of expenses associated with restructuring actions taken to improve the efficiency and profitability of certain of our manufacturing operations, expenses related to a recent business acquisition, the impact of the step-up in inventory value associated with the recent business acquisition, and the impact of the business acquisition on the timing of chassis revenue recognition. We present these adjusted Non-GAAP measures because we consider them to be important supplemental measures of our performance and believe them to be useful to improve the comparability of our results from period to period and with our competitors, as well as to show ongoing results from operations distinct from items that are infrequent or not indicative of our operating performance.

The adjusted Non-GAAP measures are not measurements of our financial performance under GAAP and should not be considered as an alternative to net income attributable to Spartan Motors, Inc. or earnings per share under GAAP. These adjusted Non-GAAP measures have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. In addition, in evaluating the adjusted Non-GAAP measures, you should be aware that in the future we may incur expenses similar to the adjustments in this presentation, despite our assessment that such expenses are infrequent or not indicative of our operating performance. Our presentation of the adjusted Non-GAAP measures should not be construed as an inference that our future results will be unaffected by unusual or infrequent items. We compensate for these limitations by providing equal prominence of our GAAP results and using adjusted Non-GAAP measures only as a supplement.

The following tables reconcile net income (loss) attributable to Spartan Motors, Inc. to Adjusted EBITDA, net income (loss) attributable to Spartan Motors, Inc. to adjusted net income (loss) attributable to Spartan Motors Inc., earnings (loss) per share to adjusted earnings per share, forecasted net income attributable to Spartan Motors, Inc. to Adjusted EBITDA and forecasted earnings (loss) per share to adjusted earnings (loss) per share for the periods indicated.
