Record Year Comparable Sales in 2020 from COVID-19 Related Pandemic Revenue

Building Supply Sales Increase by 21% to a Record $36.9 Million

FOR IMMEDIATE RELEASE

Nogales, Arizona – March 9, 2022 – 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 month period and year ended December 31, 2021.

Lloyd Hoffman, President and Chief Executive Officer of Alpha Pro Tech, commented, “The decrease in Disposable Protective Apparel segment sales in 2021 was driven by reduced demand in both our facemasks, primarily our N-95 Particulate Respirator face mask and face shields, partially offset by COVID-19 associated usage of our protective garments. Although face mask and face shield sales were down in 2021, they were higher than any other year on record, with the exception of the past pandemics in 2020 (COVID-19) and 2009 (H1N1). Due to various COVID-19 variants, sales of face masks and face shields are expected to remain higher than pre-pandemic levels in the first quarter of 2022, but it’s uncertain how long this will continue.”

“Our Building Supply segment sales were a record for the year ended December 31, 2021, with continued significant growth due to strong demand for both our synthetic roof underlayment and housewrap products. Synthetic roof underlayment sales were a record in 2021 and increased by 25.9% compared to 2020 due to the increase in inventory requirements at the dealer level, as well as the expansion of new home construction. Growth of our synthetic roof underlayment products was primarily due to robust sales of our TECHNO SB®25 product line, which was the growth driver of this product family in 2021.The housewrap line of products, with a 19.7% increase in 2021, also achieved a record due to growth in new market share as well as high demand for new home construction. Our system of selling housewrap with associated accessories is becoming increasingly accepted in the market.

The Company has committed to increasing production capacity in our Building Supply segment by investing approximately $4.0 million in new equipment, a part of which became operational in the latter part of the third quarter of 2021. As a result of delays in the supply chain, the most expensive piece of equipment has had a further delay and is now expected in the latter part of the second quarter of 2022 and is expected to be operational in the third quarter of 2022.

We are encouraged by the current demand for our Building Supply products and anticipate strong continued growth in 2022. We have continued to enjoy increased sales by utilizing a strategic approach to adding additional dealers through aggressive sales strategies, being vertically integrated and having control of our manufacturing, unlike most of our competitors. By adding the additional dealers, distribution channels and additional products in the roofing sector, we expect to maintain our sales growth. We expect our housewrap sales to continue to grow with new home construction remaining high as well as our ability to deliver products in a timely fashion by utilizing our vertically integrated manufacturing capabilities. This coupled with our growing distribution channels has been the backbone of our sales growth,” added Hoffman.

2021 Results

Net Sales

Consolidated sales for the three months ended December 31, 2021, decreased to $13.2 million, from $29.0 million for the three months ended December 31, 2020, representing a decrease of $15.8 million, or 54.5%. This decrease consisted of decreased sales in the Disposable Protective Apparel segment of $16.6 million partially offset by increased sales in the Building Supply segment of $0.8 million.

Disposable Protective Apparel segment sales for the three months ended December 31, 2021 decreased by $16.6 million, or 78.6%, to $4.5 million, compared to $21.1 million for the same period of 2020. This segment decrease was due to a 95.0% decrease in sales of face masks, primarily our proprietary N-95 Particulate Respirator face mask, a 46.9% decrease in sales of face shields and a 32.6% decrease in sales of disposable protective garments compared to the same period of 2020, all primarily due to record breaking customer demand resulting from the COVID-19 pandemic in 2020.

The sales mix of the Disposable Protective Apparel segment for the three months ended December 31, 2021 was approximately 73% for disposable protective garments, 17% for face masks and 10% for face shields. This compared to approximately 23% for disposable protective garments, 73% for face masks and 4% for face shields for the three months ended December 31, 2020.

Building Supply segment sales for the three months ended December 31, 2021 increased by $0.8 million, or 9.8%, to $8.7 million, compared to $7.9 million for the three months ended December 31, 2020.

Consolidated sales for the year ended December 31, 2021, decreased to $68.6 million, second highest in Company history, from $102.7 million for the year ended December 31, 2020, representing a decrease of $34.1 million, or 33.2%. This decrease consisted of decreased sales in the Disposable Protective Apparel segment of $40.4 million, partially offset by a $6.3 million increase in sales for the Building Supply segment.

Sales for the Disposable Protective Apparel segment for the year ended December 31, 2021, decreased by $40.4 million, or 56.0%, to $31.7 million, compared to $72.1 million for 2020. This segment decrease was due to a 3.5% increase in sales of disposable protective garments, an 80.0% decrease in sales of face masks and a 68.0% decrease in face shields, all primarily due to customer demand associated with the pandemic in 2020.

The sales mix of the Disposable Protective Apparel segment for the year ended December 31, 2021 was approximately 63% for disposable protective garments, 26% for face masks and 11% for face shields. This sales mix is compared to approximately 27% for disposable protective garments, 58% for face masks and 15% for face shields for the year ended December 31, 2020.

Building Supply segment sales for the year ended December 31, 2021 increased by $6.3 million, or 20.6%, to a record $36.9 million, compared to $30.6 million for the year ended December 31, 2020. The Building Supply segment increase was primarily due to an increase in sales of synthetic roof underlayment of 25.9%, an increase in sales of housewrap and accessories of 19.7% and basically flat sales of other woven material compared to 2020.

The sales mix of the Building Supply segment for the year ended December 31, 2021 was approximately 50% for synthetic roof underlayment, 43% for housewrap and accessories, and 7% for other woven material. This compared to approximately 48% for synthetic roof underlayment, 43% for housewrap and accessories, and 9% for other woven material for the year ended December 31, 2020.

Gross Profit

Gross profit decreased by $9.2 million, or 65.1%, to $4.9 million for the three months ended December 31, 2021, from $14.2 million for the three months ended December 31, 2020. The gross profit margin was 37.5% for the three months ended December 31, 2021, compared to 48.9% for the three months ended December 31, 2020.

Gross profit decreased by $25.2 million, or 49.9%, to $25.3 million for the year ended December 31, 2021, from $50.5 million for the year ended December 31, 2020. The gross profit margin was 36.7% for the year ended December 31, 2021, compared to 49.2% for the year ended December 31, 2020. Gross profit margin in 2021 was similar to pre-pandemic levels. The gross profit margin was negatively affected in 2021 as a result of changes in product mix as the need for face masks and face shields, which have a higher gross profit margin than our other products, declined from the surge in customer demand in 2020 as a result of the COVID-19 pandemic, as well as increases in raw material costs and ocean freight and other transportation costs.

Going forward, management believes that gross profit margin could continue to be negatively affected by the recent significant increases in ocean freight and other transportation costs as well as raw material price increases. In the current environment, cost increases may rise more rapidly than our sales prices, which could continue to decrease gross profit margin.

Selling, General and Administrative Expenses

Selling, general and administrative expenses decreased by $1.0 million, or 21.1%, to $3.9 million for the three months ended December 31, 2021, from $4.9 million for the three months ended December 31, 2020. However, as a percentage of net sales, selling, general and administrative expenses increased to 29.5% for the three months ended December 31, 2021, up from 17.0% for the same period of 2020, primarily as a result of lower net sales.

Selling, general and administrative expenses decreased by $1.6 million, or 8.9%, to $16.6 million for the year ended December 31, 2021, from $18.2 million for the year ended December 31, 2020. However, as a percentage of net sales, selling, general and administrative expenses increased to 24.1% for the year ended December 31, 2021, down from 17.7% for 2020, primarily as a result of lower net sales.

Income from Operations

Income from operations decreased by $8.2 million or 90.7%, to $846,000 for the three months ended December 31, 2021, compared to $9.1 million for the three months ended December 31, 2020. The decreased income from operations was primarily due to a decrease in gross profit of $9.2 million and an increase in depreciation and amortization expense of $23,000, partially offset by a decrease in selling, general and administrative expenses of $1.0 million. Income from operations as a percentage of net sales for the three months ended December 31, 2021 was 6.4%, compared to 31.2% for the same period of 2020.

The decreased income from operations was primarily due to a decrease in gross profit of $25.2 million and an increase in depreciation and amortization expense of $0.1 million, partially offset by a decrease in selling, general and administrative expenses of $1.6 million. Income from operations as a percentage of net sales for the year ended December 31, 2021 was 11.5%, compared to 30.8% for 2020.

The decrease in net income was largely associated with the COVID-19 pandemic in 2020. The net income decrease comparing the years ended December 31, 2021 and 2020 was due to a decrease in income before provision for income taxes of $23.7 million, partially offset by a decrease in provision for income taxes of $3.6 million. A tax benefit from stock options exercised positively impacted net income in the first quarter of 2020 by an estimated $2.0 million.

As of December 31, 2021, the Company had cash of $16.3 million compared to $23.3 million as of December 31, 2020.

Working capital totaled $50.3 million and the Company’s current ratio was 20:1, as of December 31, 2021, compared to a current ratio of 9:1 as of December 31, 2020.

Inventory increased by $8.2 million or 49.1%, to $24.9 million as of December 31, 2021, from $16.7 million as of December 31, 2020.
