ALPHA PRO TECH, LTD. ANNOUNCES FINANCIAL RESULTS FOR THE SECOND QUARTER ENDED JUNE 30, 2018

FOR IMMEDIATE RELEASE

Nogales, Arizona – August 2, 2018 – Alpha Pro Tech, Ltd. (NYSE American: 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 and six month periods ended June 30, 2018.

Lloyd Hoffman, President and Chief Executive Officer of Alpha Pro Tech, commented, “Increased sales in the second quarter were led by significant growth in our Disposable Protective Apparel segment as a result of increased sales to our major international supply chain partner and national distributors. In addition, housewrap sales in the Building Supply segment grew for the tenth consecutive quarter on a comparative basis, as we capitalize on increased demand for our innovative products amid higher levels of construction activity. We are encouraged by the rollout of our new REX™ Wrap Fortis and expect continued growth of housewrap sales in the coming quarters. Just as important and as expected, we are maintaining gross profit margins in the high thirty percent range as we grow.”

Hoffman continued, “Our balance sheet remains healthy, with ample cash and working capital to support our business and a solid base of assets that is unencumbered by debt. Our business model enables the generation of consistent free cash flow that enables us to repurchase stock on an on-going basis. At the same time, we continue to balance the repurchase of stock with investment in the business for growth and sustained profitability. We believe that this balanced approach ultimately optimizes the value of our business for the long term.”

Net sales

Consolidated sales for the second quarter of 2018 were $12.1 million, compared to $11.3 million for the second quarter of 2017, representing an increase of $827,000, or 7.3%. The increase was primarily due to increased sales in the Building Supply segment of $289,000 and increased sales in the Disposable Protective Apparel of $614,000, partially offset by decreased sales in the Infection Control segment of $76,000.

Building Supply segment sales for the three months ended June 30, 2018 increased by 4.6% to $6.6 million, compared to $6.3 million for the same period of 2017. The sales mix of the Building Supply segment for the three months ended June 30, 2018 was 49% for housewrap, 39% for synthetic roof underlayment and 12% for other woven material. Comparatively, the sales mix for the second quarter of 2017 was 40% for housewrap, 51% for synthetic roof underlayment and 9% for other woven material.

Sales for the Disposable Protective Apparel segment for the three months ended June 30, 2018 increased by $614,000, or 16.3% to $4.4 million, compared to $3.8 million for the same period of 2017.

Infection Control segment sales for the three months ended June 30, 2018 decreased by $76,000, or 6.2%, to $1.15 million, compared to $1.23 million for the same period of 2017.

Consolidated sales for the six months ended June 30, 2018 increased 6.9% to $23.6 million, compared to $22.0 million for the same period of 2017. The increase was primarily due to increased sales in the Building Supply segment of $1,019,000 and increased sales in the Disposable Protective Apparel of $552,000, partially offset by decreased sales in the Infection Control segment of $52,000.

Building Supply segment sales for the first six months of 2018 increased by $1.0 million, or 8.3%, to $13.2 million, compared to $12.2 million for the same period of 2017. The increase was primarily due to an increase in sales of housewrap and an increase in sales of other woven material, partially offset by a decrease in sales of synthetic roof underlayment.

Sales for the Disposable Protective Apparel segment for the six months ended June 30, 2018 increased by $552,000, or 7.8%, to $7.6 million, compared to $7.1 million for the same period of 2017. The increase was primarily due to increased sales to the Company’s major international supply chain partner, as well as national and regional distributors.

Infection Control segment sales for the six months ended June 30, 2018 decreased by $52,000, or 1.9%, to $2.69 million, compared to $2.74 million for the same period of 2017. 

Gross profit

Gross profit for the second quarter of 2018 increased by 5.2% to $4.7 million, or 39.0% gross profit margin, compared to $4.5 million, or 39.8% gross profit margin, for the same period of 2017.

Gross profit for the six months ended June 30, 2018 increased by 4.5% to $9.2 million, compared to $8.8 million for the same period of 2017. The gross profit margin was 39.0% for the six months ended June 30, 2018, compared to 39.9% for the same period of 2017. Management expects gross profit margin to be reduced in 2018 but still to be in the high thirty percent range.

Selling, general and administrative expenses

Selling, general and administrative expenses increased by $122,000, or 3.6%, to $3.5 million for the second quarter of 2018, compared to $3.3 million for the same period of 2017. The increase was driven by sales team expansion and enhancement of marketing programs in the Building Supply and Disposable Protective Apparel segments.

Selling, general and administrative expenses increased by $530,000, or 7.8%, to $7.3 million for the six months ended June 30, 2018, up from $6.8 million for the same period of 2017. The increase was primarily the result of expenses associated with the settlement of a litigation matter. Excluding the expense for the settlement, selling, general and administrative expenses would have been relatively flat as compared to the same period last year.

Net income

Net income for the second quarter of 2018 was $959,000, compared to $804,000 for the same period of 2017, an increase of $155,000, or 19.3%. Net income as a percentage of net sales for the second quarter of 2018 was 7.9%, compared to 7.1% for the second quarter of 2017. Basic and diluted earnings per common share for the second quarters of 2018 and 2017 were $0.07 and $0.05, respectively.

Net income for the six months ended June 30, 2018 was $1.5 million, compared to $1.4 million for the same period of 2017, an increase of 8.3%. The increase in net income was due to a decrease in provision for income taxes of $270,000, partially offset by a decrease in income before provision for income taxes of $157,000. Net income as a percentage of net sales for the six months ended June 30, 2018 was 6.2%, compared to 6.1% for the same period of 2017. Basic and diluted earnings per common share for the six months ended June 30, 2018 and 2017 were $0.10 and $0.09, respectively. Net income for the six months ended June 30, 2018, excluding the settlement expense mentioned above, would have been significantly higher than the six months ended June 30, 2017.

Balance Sheet

The consolidated balance sheet remained strong with a cash balance of $7.2 million as of June 30, 2018, a decrease of $1.6 million from $8.8 million as of December 31, 2017. The decrease in cash was due to cash used in financing activities of $1,497,000, primarily from the repurchase of common stock, and cash used in investing activities of $240,000, partially offset by cash provided by operating activities of $132,000. The Company ended the second quarter of 2018 with working capital of $24.1 million and a current ratio of 12:1.

Inventory decreased by $558,000, or 5.4%, to $9.7 million as of June 30, 2018, down from $10.2 million as of December 31, 2017. The decrease was primarily due to a decrease in inventory for the Disposable Protective Apparel segment of $386,000, or 11.2%, to $3.1 million and a decrease in inventory for the Building Supply segment of $315,000, or 6.9%, to $4.3 million, partially offset by an increase in inventory for the Infection Control segment of $143,000, or 6.5%, to $2.4 million.

Colleen McDonald, Chief Financial Officer, commented, “At the end of the second quarter of 2018, we had $2.7 million available for additional stock purchases under our stock repurchase program. During the six months ended June 30, 2018, we repurchased 453,000 shares of common stock at a cost of $1.6 million, bringing the program total to 16,657,007 shares of common stock repurchased at a cost of $30.6 million since the program’s inception. All stock is retired upon repurchase, and future repurchases are expected to be funded from cash on hand and cash flows from operating activities.”

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