FOR IMMEDIATE RELEASE

Nogales, Arizona – March 5, 2013 – Alpha Pro Tech, Ltd. (NYSE MKT: APT), a leading manufacturer of products designed to protect people, products and environments, including disposable protective apparel and building products, today announced financial results for the three months and year ended December 31, 2012.

Consolidated sales for the fourth quarter increased 7.5% to $9.8 million from $9.2 million for the comparable quarter of 2011. Building Supply segment sales for the three months ended December 31, 2012 increased by 23.3% to $5.9 million compared to $4.8 million for the same period of 2011. The sales mix of the Building Supply segment for the three months ended December 31, 2012 was 66% for synthetic roof underlayment and 34% for housewrap. This compared to 69% for synthetic roof underlayment and 31% for housewrap for the fourth quarter of 2011. Sales for the Disposable Protective Apparel segment for the three months ended December 31, 2012 decreased 14.7% to $3.0 million, compared to $3.5 million for the same period of 2011. Infection Control segment sales for the three months ended December 31, 2012 increased by 10.9% to $973,000 compared to $877,000 for the same period of 2011.

Al Millar, President of Alpha Pro Tech, commented, “Overall sales increased for the fourth quarter of 2012 from the prior year period, led by a strong quarter of Building Supply and Infection Control segment sales. In early 2012, we introduced TECHNOply™, an economy version of our synthetic roof underlayment, to capture market share in the lower end of the market. This product contributed approximately 14% in the most recent quarter and contributed approximately 6% of total synthetic roof underlayment sales for 2012. We expect this to be a growth product for the Company. Sales of our REX™ Wrap Fortis non-perforated breathable housewrap continue to be lower than anticipated, although sales of this product are expected to contribute more significantly to the sales line in 2013. We saw increased sales of this product in the fourth quarter of 2012, which accounted for almost half of the product’s total sales in 2012, and we expect new distribution in the coming year. We believe that the outlook for the Building Supply segment is promising and that we are in a good position to take advantage of significant growth prospects as the housing market continues to recover.”

Consolidated sales for the year ended December 31, 2012 increased 6.6% to $41.1 million from $38.5 million for 2011. This increase consisted of increased sales in the Building Supply and Disposable Protective Apparel segments, partially offset by decreased sales in the Infection Control segment.

Building Supply segment sales for the year ended December 31, 2012 increased 10.0% to $23.7 million, compared to $21.6 million for 2011. The sales mix of the Building Supply segment for the year ended December 31, 2012 was 67% for synthetic roof underlayment and 33% for housewrap. This compares to 69% for synthetic roof underlayment and 31% for housewrap for 2011. Sales for the Disposable Protective Apparel segment for the year ended December 31, 2012 increased 5.0% to $13.2 million, compared to $12.6 million for 2011. Infection Control segment sales for the year ended December 31, 2012 decreased by 5.2% to $4.1 million, compared to $4.3 million for 2011. Mask sales were down by 4.2% to $2.8 million, and sales of medical bed pads and pet beds were down $100,000 to $0, as the product line was sold in the first quarter of 2011. Shield sales were down by 0.2% to $1.4 million. The overall mask sales decrease for 2012 was primarily due to a decline in industrial mask sales as a result of our previous largest industrial distributor launching its own line of masks, partially offset by an increase in medical mask sales.

Gross profit for the three months ended December 31, 2012 increased by 4.7% to $3.4 million, or 34.4% gross profit margin, compared to $3.2 million, or 35.3% gross profit margin, for the same period in 2011. Gross profit for the year ended December 31, 2012 increased 2.9% to $14.5 million, or 35.2% gross profit margin, from $14.0 million, or 36.5% gross profit margin, for 2011. The gross profit margin for the year ended December 31, 2012 was affected by the Building Supply segment margin, which has declined due to increased raw material costs and competitive pricing pressures.

Selling, general and administrative expenses increased by 26.6% to $3.3 million for the fourth quarter of 2012 from $2.6 million for the same quarter of 2011. As a percentage of net sales, selling, general and administrative expenses increased to 33.8% for the three months ended December 31, 2012 from 28.7% for the same period of 2011.  

Selling, general and administrative expenses for the year ended December 31, 2012 increased by 4.5% to $12.9 million from $12.3 million for 2011. The increase was primarily due to increased sales and marketing expenses for both the Building Supply and Disposable Protective Apparel segments, which enjoyed revenue growth in 2012. In addition, executive bonuses were declined in 2011. As a percentage of net sales, selling, general and administrative expenses decreased to 31.4% for the year ended December 31, 2012 from 32.0% for 2011.

Net income decreased by 66.8% for the three months ended December 31, 2012 to $118,000, compared to $355,000 for the three months ended December 31, 2011. Net income as a percentage of net sales for the three months ended December 31, 2012 and 2011 was 1.2% and 3.9%, respectively. Basic and diluted net income per common share for the three months ended December 31, 2012 and 2011 were $0.01 and $0.02, respectively.

Net income increased by 4.7% for the year ended December 31, 2012 to $977,000, compared to $933,000 for 2011. Net income as a percentage of net sales for the year ended December 31, 2012 and 2011 was 2.4% and 2.4%, respectively. Basic and diluted net income per common share for the years ended December 31, 2012 and 2011 were $0.05 and $0.04, respectively.

The consolidated balance sheet remained strong with a current ratio of 19:1 as of December 31, 2012, compared to 35:1 as of December 31, 2011. The Company completed the fourth quarter of 2012 with working capital of $29.6 million. 

Lloyd Hoffman, the Company’s Chief Financial Officer, commented, “Cash and cash equivalents decreased by 39.3%, or $2.9 million, to $4.6 million as of December 31, 2012, compared to $7.5 million as of December 31, 2011. The decrease in cash and cash equivalents was primarily due to increased inventory levels, payments for the repurchase of common stock and longer payment terms offered as an end-of-year promotion to building supply customers. Our cash position is expected to improve as of March 31, 2013, as the majority of the extended receivables should be collected by then.”

Inventory increased by $1.6 million, or 10.3%, to $17.2 million as of December 31, 2012 from $15.6 million as of December 31, 2011. The increase was primarily due to an increase in inventory for the Building Supply segment of $845,000, or 11.8%, to $8.0 million, and an increase in inventory for the Disposable Protective Apparel segment of $940,000, or 20.4%, to $5.6 million, partially offset by a decrease in inventory for the Infection Control segment of $187,000, or 4.9%, to $3.6 million. As of December 31, 2012, Disposable Protective Apparel inventory was higher than historical levels due to the Company’s purchasing more inventory in 2012 to account for the anticipated shut down of manufacturing during the Chinese New Year.

Mr. Hoffman concluded, “As of December 31, 2012, we had $729,000 available for additional stock purchases under our stock repurchase program. For the year ended December 31, 2012, we repurchased 1,085,050 shares of common stock at a cost of $1,581,000. As of December 31, 2012, we had repurchased a total of 8,593,628 shares of common stock at a cost of $10,792,000 through our repurchase program. We retire all stock upon its repurchase. Future repurchases are expected to be funded from cash on hand and cash flows from operating activities. Subsequent to year end, the Company’s Board of Directors authorized a $2.0 million expansion of the Company’s existing share repurchase program.”  

The Company currently has no outstanding debt and maintains an unused $3.5 million credit facility. The Company believes that cash generated from operations, current cash balances and the borrowings available under its credit facility will be sufficient to satisfy projected working capital needs and planned capital expenditures for the foreseeable future.
