Nogales, Arizona — October 27, 2009, Alpha Pro Tech, Ltd. (NYSE Amex: APT), a leading manufacturer of products designed to protect people, products and environments, including disposable protective apparel and building products, today announced its financial results for the third quarter and the nine months ended September 30, 2009.

Consolidated sales for the third quarter of 2009 increased 65.3% to a quarterly record of $16.9 million from $10.2 million in the comparable quarter in 2008. Building Supply (formerly known as Engineered Products) segment sales for the third quarter of 2009 increased by 67.7% to a quarterly record of $5.3 million, compared to $3.2 million in the same quarter of 2008. This quarterly record is also up 40.8% sequentially from the previous quarterly record of $3.8 million set in the second quarter of 2009. The increase for the quarter is primarily due to a 72.6% increase in sales of REX™ Synfelt synthetic roof underlayment and a 52% increase in sales of REX™ Wrap house wrap. The sales mix of the Building Supply segment for the third quarter of 2009 was 75% for synthetic roof underlayment and 25% for house wrap. This is compared to 72% for synthetic roof underlayment and 28% for house wrap in the third quarter of 2008. Sales for the

Disposable Protective Apparel segment decreased by 3.2% to $5.3 million, compared to $5.4 million for the same period of 2008. Infection Control segment sales for the third quarter of 2009 increased by 290.1% to a quarterly record of $6.3 million, compared to $1.6 million in the same quarter of 2008. This quarterly record is also up 34.4% sequentially from the previous quarterly record of $4.7 million set in the second quarter of 2009. Mask sales were up by 378.9%, or $ 4.2 million, and shield sales were up by 156.5%, or $ 0.5 million.

Al Millar, President of Alpha Pro Tech commented, “We experienced significant increases in demand for our N-95 respirator masks due to the H1N1 Influenza A pandemic. N-95 respirator mask sales are expected to continue to grow significantly in the fourth quarter from current levels and are expected to be substantially stronger than normal for the foreseeable future amidst concerns regarding the global H1N1 Influenza A pandemic. Sales for the Disposable Protective Apparel segment were adversely affected by a supply chain issue in which goods from Asia were delayed due to the high demand for H1N1 products.”

Mr. Millar continued, “Our REX™ Synfelt synthetic roof underlayment is perceived as a superior product in the industry, and, as the market evolves from felt paper to synthetic roof underlayment, which is a significant opportunity for the Company, we believe that we are in a very good position to secure market share. Additionally, our high-quality, multi-color printed house wrap gives us a distinct competitive advantage in the marketplace, and our market share is expanding even during this weak building market and economic downturn. Our Building Supply segment distribution channel strategy continues to strengthen each and every quarter and should continue to broaden our ability to take advantage of market opportunities throughout this year and into the future.”

Consolidated sales for the nine months ended September 30, 2009 increased 52.9% to $40.8 million from $26.7 million in the same period of 2008. Building Supply segment sales increased by 75.6% to $11.3 million from $6.4 million in the same period last year, primarily due to a 100.2% increase in sales of REX™ Synfelt synthetic roof underlayment and a 32.7% increase in sales of REX™ Wrap house wrap. The sales mix of the Building Supply segment for the first nine months of 2009 was 71% for synthetic roof underlayment and 29% for house wrap. This is compared to 62% for synthetic roof underlayment and 38% for house wrap in 2008. Sales for the Disposable Protective Apparel segment increased 6.2% to $16.2 million from $15.2 million, primarily related to increased sales to the Company’s largest distributor as well as increased sales to a broad base of the Company’s distribution network. Infection Control segment sales increased by 166.2% to $13.3 million from $5.0 million. Mask sales were up by 201.1%, or $6.6 million, and shield sales were up by 173.8%, or $1.9 million.

Gross profit increased by 88.5% to $8.2 million for the third quarter of 2009 from $4.4 million for the third quarter of 2008. The gross profit margin was 48.6% for the third quarter of 2009, compared to 42.6%, in the same quarter in 2008. Gross profit increased by 63.8% to $19.2 million for the nine months ended September 30, 2009 from $11.7 million for the same period in 2008. The gross profit margin was 47.1% for the first nine months of 2009, compared to 44.0% for the same period in 2008.

Gross profit margin for the three and nine months ended September 30, 2009 was positively affected by the change in product mix in which Infection Control segment sales, which have higher margins, increased as a percentage of total sales.

Selling, general and administrative expenses increased by 18.9% to $3.7 million for the third quarter 2009 from $3.1 million in the same quarter last year. As a percentage of net sales, selling, general and administrative expenses decreased to 21.7% for the third quarter of 2009 from 30.1% in the same quarter of 2008. Selling, general and administrative expenses increased by $0.9 million, or 9.4%, to $10.3 million for the first nine months of 2009 from $9.4 million in the same period in 2008. As a percentage of net sales, selling,

general and administrative expenses decreased to 25.3% for the first nine months of 2009 from 35.3% in the same period in 2008.

Selling, general and administrative expenses as a percentage of sales are significantly lower in 2009, and the Company believes that it can now effectively leverage the infrastructure that it has built to substantially grow the business, while decreasing expenses as a percentage of sales.

Net income for the third quarter of 2009 increased by 278.8% to a quarterly record of $2.8 million, compared to net income of $745,000 in the third quarter of 2008. Net income as a percentage of sales for the third quarter of 2009 and 2008 was 16.7% and 7.3%, respectively. Basic income per share for the third quarter of 2009 and 2008 was $0.13 and $0.03, respectively. Diluted income per share for the third quarter of 2009 and 2008 was $0.12 and $0.03, respectively.

Net income for the first nine months of 2009 increased 333.8% to $5.5 million, compared to net income of $1.3 million in the same period in 2008. Net income as a percentage of sales for the first nine months of 2009 and 2008 was 13.5% and 4.8%, respectively. Basic and diluted income per share for the first nine months of 2009 and 2008 was $0.24 and $0.05, respectively.

The Consolidated balance sheet continued to remain strong with a current ratio of 6:1 on September 30, 2009. The Company completed the quarter with cash and cash equivalents of $9.1 million, up 98.4% from $4.5 million as of December 31, 2008, and working capital of $25.4 million. Inventories as of September 30, 2009 decreased by $2.6 million to $9.4 million, compared to $12.1 million as of December 31, 2008.

Lloyd Hoffman, Chief Financial Officer, commented, “Inventory decreased by 21.7% primarily due to a decrease in inventory for the Building Supply segment. Our strong financial performance led to an increase in cash of $4.5 million to $9.1 million. This increase was primarily due to cash provided by operating activities of $6.8 million, partially offset by $2.1 million in cash used to repurchase stock. During the nine months ended September 30, 2009, we repurchased and retired 1,554,900 shares of common stock. As of September 30, 2009, we have repurchased and retired a total of 6,193,800 shares of common stock at a cost of $7.7 million through our repurchase program. Future repurchases are expected to be funded from cash on hand and cash flow from operations.”

The Company currently has no outstanding debt and maintains an unused $3.5 million credit facility.
