{Slide 4 – 2nd Quarter Highlights}

Our second quarter results continued to be strong on a year–over-year basis. A few highlights from the quarter are:

{Slide 5 – Consolidated Financial Results}

I would now like to review our first half consolidated performance.

Fiscal 2014 first half adjusted operating income was $8.9 million and adjusted net income was $6.0 million or $0.59 per share basic and diluted, versus adjusted operating income of $6.9 million and adjusted net income of $4.6 million or $0.45 per share diluted, for the first half of fiscal 2013.

Our consolidated revenue, with acquisitions included, was $159 million, increasing 34% or $41 million from the same period in the prior year. Without the influence of Onyx, Creonix, Aydin, and Beckwood acquisitions, legacy revenue was $122 million, up $10 million or 9% from the prior year.

Our gross profit in the first half of fiscal 2014 was $27 million or 17.1% compared to $20.1 million or 17.0% in the first half of fiscal 2013.

Selling and administrative expenses increased to $16.3 million in the fiscal 2014 first half as compared to $12.8 million in the prior year first half, but as a percentage of sales reduced to 10.3% as compared to 10.9% in the prior year first half. The dollar increase relates to the addition of SG&A related to the four acquisitions.

{Slide 6 – Adjusted EBITDA}

The adjusted EBITDA for second quarter of fiscal 2014 increased 28% to $7.4 million or 8.8% of sales as compared to $5.8 million or 8.7% of sales in the same quarter of the prior year. Year-to-date adjusted EBITDA increased 51% to $12.9 million or 8.1% of sales as compared to $8.5 million or 7.2% of sales. The YTD increase reflects organic growth from all three segments as well as the impact of the completed acquisitions.

I would now like to turn over the next portion of today’s call to Mark so that he can update you on our individual segment results and our liquidity and capital resources.

MARK SCHLEI (CFO) SPEAKS

Thanks Cary.

{Slide 7 – Operating Results}

Included in the results for the Company’s Medical segment for the three months ended December 31, 2013 are net sales of approximately $13.1 million resulting from the acquisition of Onyx compared to $6.1 million in net sales from the acquisition of Onyx in the prior year quarter. Excluding the $7.0 million in incremental sales from the acquisition of Onyx, legacy Medical sales increased approximately $2.5 million, or 9%, in the three months ended December 31, 2013 as compared with the prior year quarter. Reflected within this increase in legacy sales is $4.4 million of increased sales to three customers, including this business unit’s largest customer, reflecting relative demand for these customers’ products. Offsetting these increases were decreased sales to one customer totaling $1.6 million, reflecting a non-Sparton supplier issue.

The gross profit percentage on Medical sales increased to 15.4% from 12.5% for the three months ended December 31, 2013 and 2012, respectively. This increase in margin percentage on Medical sales primarily reflects certain favorable product mix between the two periods, partially offset by the impact of increased depreciation at the Onyx facility.

Included in the results for the Company’s Complex Systems segment for the three months ended December 31, 2013 are net sales of approximately $3.1 million resulting from the acquisitions of Creonix and Beckwood. Excluding these sales and a decrease in intercompany sales of $0.1 million, CS sales to legacy external customers for the three months ended December 31, 2013 increased $1.3 million, or 13%, as compared with the same quarter last year, primarily reflecting $2.4 million of increased sales to three customers, reflecting relative increased demand for each of these customers’ products. Partially offsetting these increases was decreased sales of $0.9 million to one customer reflecting this customer’s disengagement during fiscal 2014.

The gross profit percentage on CS sales increased to 10.6% for the three months ended December 31, 2013 compared to 10.2% for the three months ended December 31, 2012, primarily reflecting increased capacity utilization, partially offset by unfavorable product mix between the two periods.

Included in the results for the Company’s Defense and Security Systems segment for the three months ended December 31, 2013 are net sales of approximately $4.0 million resulting from the acquisition of Aydin. Excluding the fiscal year 2014 incremental sales from the acquisition of Aydin, DSS legacy sales decreased approximately $0.6 million, or 3%, in the three months ended December 31, 2013 as compared with the same quarter last year, reflecting decreased sonobuoy sales to foreign governments, offset by increased U.S. Navy sonobuoy sales.

The gross profit percentage on DSS sales decreased to 23.8% for the three months ended December 31, 2013 compared to 27.9% for the three months ended December 31, 2012. Gross profit percentage was negatively affected in the current year quarter by decreased foreign sonobuoy sales as compared to the prior year quarter.

{Slide 8 – Liquidity & Capital Resources}

I would now like to review our current debt and liquidity positions as of the end of the quarter. As of December 31, 2013, the Company had $25.0 million borrowed and $40 million available under its credit facility and had available cash and cash equivalents of $1.0 million. As of this

date, the Company had received performance based payments under U.S. Navy contracts in excess of the funding of production to date under those contracts of $19.1 million. The Company’s debt-to-equity ratio was 0.26 to 1 and adjusted debt-to-EBITDA leverage was 1.0x at December 31, 2013.

Summarizing our cash flows, operating activities provided $12.5 million and used $8.9 million of net cash flows in six months ended December 31, 2013 and 2012, respectively. Excluding changes in working capital, operating activities provided $10.2 million and $9.8 million in the first six months of fiscal 2014 and 2013, respectively, reflecting the Company’s relative operating performance during those periods. Working capital provided $2.3 million and used $18.7 million of net cash flows in the six months ended December 31, 2013 and 2012, respectively.

Cash flows used in investing activities in the six months ended December 31, 2013 and 2012 totaled $31.5 million and $45.4 million, respectively. The six months ended December 31, 2013 reflect the $15.0 million acquisition of Aydin and the $15.3 million acquisition of Beckwood. Both acquisitions are subject to certain post-closing adjustments. The Aydin acquisition was funded through borrowings under the Company’s Credit Facility. The Beckwood acquisition was funded through a combination of cash on hand and borrowings under the Company’s Credit Facility. The six months ended December 31, 2012 reflect the $43.5 million acquisition of Onyx.

I would now like to turn the presentation back over to Cary.

CARY WOOD (President & CEO) SPEAKS

Thanks Mark.

{Slide 9 –Acquisition Update}

On December 11, 2013, the Company completed the acquisition of Beckwood Services, Inc., located in Plaistow, New Hampshire, one hour north of Boston. The acquired business, which will be part of the Company’s Complex Systems segment, is expected to add approximately $18 million in annualized revenue. Beckwood develops electronic or electro-mechanical controls and electronic assemblies and their customer profile includes international Fortune 1000 manufacturers of industrial control systems, analytical instruments, measuring and detecting equipment, and military, defense and Homeland Security equipment.

This addition continues to meet aspects of our growth strategy by providing Sparton’s entrance into the Northeast geographic market as well as adding industrial control capabilities that further enhance our offerings within the electromechanical value stream.

Integration activities will be minimal and we expect it to be accretive to earnings within the first 12 months.

{Slide 10 – Fiscal 2014 Outlook}

As in the past, we will be presenting at various conferences, meeting with our existing investors, and calling on potential new investors throughout the year. In the near term, some of the events that will be occurring in the upcoming months are:

In conclusion, as Sparton continues to implement its strategic growth plan, we expect to continue to achieve our growth expectations by focusing on new business development, internal product research and development, and compatible acquisitions. To that end, the results of the first half of the year have demonstrated the success we’ve had at executing the plan and we look forward at carrying this momentum through fiscal 2014 and beyond.

Lastly, we are pleased to have acquired Beckwood Services and welcome the entire team to the Sparton family.

Thank you for your continued support.
