SCHAUMBURG, IL -- Sparton today announced fourth-quarter net income was $6.8 million, up 68% year-over-year for the period ended June 30. Overall fourth-quarter sales of $87.1 million were up 42% from last year.

Sparton, which is made up of three business units, saw total sales for the year rise 19% to $266 million, including year-over-year organic growth of 5%.

For the quarter medical sales increased $3.4 million from the prior year, excluding incremental sales from the acquisition of Onyx EMS. The acquisition of Onyx resulted in net sales of $31.2 million for the year, including $13.1 million for the fourth quarter.

Complex Systems' sales to external customers increased $800,000, or 7%, from last year. The results don't include an increase in intercompany sales of $900,000 and $300,000 of incremental sales from the acquisition of Creonix. Complex Systems includes most of the company's former electronics manufacturing services unit.

President and CEO Cary Wood said, “Since its turnaround began in 2009, we have been paying close attention to the performance of this segment. At that time, CS represented over 50% of Sparton’s revenue while also being the largest contributor to the company’s overall financial losses due to significant operational challenges such as suboptimal service levels and excess capacity. This segment has been revitalized to the point where it has been consolidated into two profitable locations with enhanced management teams, has increased service levels to all-time highs and ahead of industry benchmarks, and has evolved the Vietnam facility into a key strategic asset for many of our current and future customers. In the past year alone, Complex Systems’ revenue grew 13%, 19 new programs were awarded, and it added complex device build and wire harness design and assembly capabilities. We strongly believe that the Complex Systems segment has returned to an acceptable, near term level of profitability and has the momentum to effectively further contribute to the company’s success in the years to come.”

Defense & Security Systems' sales increased $8.3 million, or 40%, on higher demand for sonobuoys.
