FOR IMMEDIATE RELEASE

Supreme Industries Reports Significantly Improved 2012 Earnings

Full-Year Net Income Surges to $11.8 Million from $0.8 Million in 2011

Net Income per Diluted Share Increases to $0.77 from $0.05 in Prior Year

Goshen, Ind.—Feb. 7, 2013—Supreme Industries, Inc. (NYSE MKT: STS), a leading manufacturer of specialized commercial vehicles including truck bodies, shuttle buses, and armored vehicles, today announced significantly improved earnings for its full year ended Dec. 29, 2012.

2012 Fourth-Quarter Results

Consolidated net sales of $57.7 million for the fourth quarter declined 11.8% from $65.5 million in last year’s comparable period. The lower sales related to two large orders in the fourth quarter of 2011 that were not repeated in 2012, along with intense competition and increased discounting in the bus industry on state and municipal bid orders.

Gross margin as a percentage of sales declined slightly to 13.2%, compared with 13.4% in last year’s fourth quarter. Gross profit declined to $7.6 million from last year’s $8.7 million on the lower sales volume and a change in product mix.  Other income increased $0.2 million due to a gain on sale of an investment.  For the quarter, the Company reported net income of $0.4 million, or $0.02 per diluted share, compared with net income of $1.9 million, or $0.12 per diluted share, in the fourth quarter of 2011.

Supreme’s Chief Financial Officer and Interim Chief Executive Officer Matthew Long said: “We continue to successfully implement the strategy of concentrating on sales and markets that meet or exceed our margin criteria. By enhancing manufacturing efficiencies and better managing costs, we have successfully developed a model that can drive sustainable profits into the future. Entering 2013, we are encouraged by our team’s progress to date, and by the opportunities we see before us to continue satisfying our customers with on-time delivery of specialty vehicles that represent the very best quality, safety and value.”

2012 Full-Year Results

Consolidated net sales decreased 4.7%, to $286.1 million, from $300.4 million last year. Gross profit increased 33.9%, to $43.5 million, from 2011’s $32.5 million. Gross profit, as a percentage of sales, improved dramatically to 15.2%, compared with 10.8% in 2011.  The 4.4% increase in gross margin percentage is the result of refined pricing methodologies, improved labor efficiencies and the redesign of certain manufacturing facilities.

The Company reported full-year income from continuing operations of $11.8 million, or $0.77 per diluted share, compared with last year’s income from continuing operations of $1.7 million, or $0.11 per diluted share. Net income for the full year improved to $11.8 million, or $0.77 per diluted share, compared with net income of $0.8 million, or $0.05 per diluted share in 2011, which included the impact from discontinued operations.

The Company’s effective tax rate was 5.9% for the year ending Dec. 29, 2012, substantially lower than statutory rates due to the reversal of deferred tax asset reserves and the use of net operating loss carryforwards.   Reported financial results in 2011 included an income tax benefit of $0.4 million recorded in the fourth quarter, resulting from expiring state statues related to uncertain tax positions. Beginning with the first quarter of 2013, the Company expects to recognize income taxes at more normalized rates.

Working capital was $38.6 million at Dec. 29, 2012, up from $35.4 million at Dec. 31, 2011.  The working capital ratio was 2.7 to 1 versus 2.0 to 1 for the respective periods.  During 2012, Supreme invested $7.1 million in facilities and equipment to enhance efficiencies and $6.1 million to exercise two related-party lease purchase options.   On Dec. 19, 2012, the Company entered into a five-year revised cash flow credit agreement increasing its line of credit to $45 million with improved liquidity, availability and interest rate pricing.  Total debt declined to $14.1 million at year end, compared with $15.9 million last year. Stockholders’ equity increased 22% to $67.2 million, or $4.41 per share, at Dec. 29, 2012, compared with $54.9 million, or $3.71 per share, at Dec. 31, 2011. Net cash provided by operating activities during 2012 totaled $12.4 million, compared with $14.5 million in 2011.

As disclosed in the second quarter of 2012, the Company self-identified an immaterial error related to revenue recognition. Accordingly, its consolidated financial statements reflect the correction of the immaterial error.
