ALPHA PRO TECH, LTD. ANNOUNCES RECORD FINANCIAL RESULTS FOR THE FOURTH QUARTER AND YEAR ENDED DECEMBER 31, 2020

Record Full Year Net Sales of $102.7 Million, an Increase of 120% Year-Over-Year

Record Full Year Net Income of $27.1 Million, or $1.94 per diluted share

FOR IMMEDIATE RELEASE

Nogales, Arizona – March 9, 2021 – 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 fourth quarter and full year ended December 31, 2020.

Lloyd Hoffman, President and Chief Executive Officer of Alpha Pro Tech, commented, “Alpha Pro Tech delivered an exceptional year, reaching several milestones, including surpassing $100 million in revenue, over $27 million in net income and $1.94 diluted earnings per share. 2020 was a record year for face masks, with sales totaling $41.8 million, blowing past the prior record set in 2009 during the H1N1 pandemic by a multiple of 2.4 times. Face mask sales grew during each quarter of 2020. Fourth quarter face mask sales were $15.4 million, compared $13.4 million in the third quarter of 2020, $8.5 million in the second quarter of 2020 and $4.5 million in the first quarter of 2020. The increase in face mask sales was primarily attributable to increased sales of our proprietary N-95 Particulate Respirator face mask, manufactured in Salt Lake City, Utah, resulting from increased customer demand associated with the COVID-19 pandemic.”

Mr. Hoffman continued, “We also saw a record year in 2020 for face shield sales, which increased by a multiple of 2.9 times compared to the prior record set in 2009. Sales of our disposable protective garments increased by an impressive 23.7% in 2020.”

Mr. Hoffman added, “Despite the challenges of 2020, our Building Supply segment experienced a record year with growth across all product lines. Our TECHNO family of synthetic roof underlayment products showed continued growth as a result of strong sales of our TECHNO SB®25 product line, which was instrumental in the 16.4% growth of this family of products in 2020. Housewrap sales also hit record levels in 2020, and the addition of housewrap accessories, namely flashing and tape products, to our portfolio opened up new market distribution opportunities and contributed to an increase of housewrap sales of 12.5%. Sales of both synthetic roof underlayment and housewrap benefitted from an increase in new home construction during 2020 and management’s determination to expand the Company’s distribution reach to cover the new home growth. As anticipated, sales of our other woven materials improved in 2020, with an increase of 20.2%, as our historically largest customer for these products resumed its normal buying pattern.”

Looking Ahead

Mr. Hoffman continued, “As we turn the page on a record 2020 and look ahead to 2021, we expect the market for our products to normalize in some respects, although we believe that sales will remain strong as compared to historical levels. More specifically:

Management will continue to carefully monitor the current dynamic market conditions and work to respond to them swiftly and effectively.”

Consolidated sales for the year ended December 31, 2020 increased to a record $102.7 million, from $46.7 million for the year ended December 31, 2019, representing an increase of $56.0 million, or 120.1%. This increase consisted of increased sales in the Disposable Protective Apparel segment of $52.0 million and increased sales in the Building Supply segment of $4.0 million compared to 2019.

Disposable Protective Apparel Segment

Sales for the Disposable Protective Apparel segment for the year ended December 31, 2020 increased by $52.0 million, or 259.0%, to a record $72.1 million, compared to $20.1 million for 2019, primarily driven by increased demand resulting from the COVID-19 pandemic. This segment increase was due to a 1,262% increase in sales of face masks, a 631.2% increase in face shields and a 23.7% increase in sales of disposable protective garments. The sales mix of the Disposable Protective Apparel segment for the year ended December 31, 2020 was approximately 58% for face masks, 15% for face shields and 27% for disposable protective garments. This sales mix is compared to approximately 15% for face masks, 8% for face shields and 77% for disposable protective garments for the year ended December 31, 2019.

Building Supply Segment

Building Supply segment sales for the year ended December 31, 2020 increased by $4.0 million, or 15.1%, to a record $30.6 million, compared to $26.6 million for the year ended December 31, 2019. The Building Supply segment increase was primarily due to an increase in sales of synthetic roof underlayment of 16.4%, an increase in sales of housewrap of 12.5% and an increase of sales of other woven material of 20.2% compared to 2019.

The sales mix of the Building Supply segment for the year ended December 31, 2020 was approximately 48% for synthetic roof underlayment, 43% for housewrap and 9% for other woven material. This compared to approximately 47% for synthetic roof underlayment, 44% for housewrap and 9% for other woven material for the year ended December 31, 2019.

Gross Profit

Gross profit increased by $10.3 million, or 269.0%, to $14.2 million for the three months ended December 31, 2020, from $3.8 million for the same period of 2019. The gross profit margin was 48.9% for the three months ended December 31, 2020, compared to 35.2% for the same period of 2019. The gross profit margin was positively affected by the significant change in product mix, which was altered due to a surge in customer demand as a result of the COVID-19 pandemic for face masks, specifically the Company’s N-95 Particulate Respirator face mask, and face shields, which generally have a higher gross profit margin than the Company’s other products.

Gross profit increased by $33.5 million, or 197.4%, to $50.5 million for the year ended December 31, 2020, from $17.0 million for 2019. The gross profit margin was 49.2% for the year ended December 31, 2020, compared to 36.4% for the year ended December 31, 2019.

Gross profit margin in 2020 was significantly higher than historical levels, but management believes that gross profit margin could be negatively affected in 2021 as a result of potential changes in product mix and changes in distribution channels associated with the pandemic, as well as expected increases in raw material costs, resin in particular, and ocean freight and other transportation costs.

Selling, General and Administrative Expenses

Selling, general and administrative expenses increased by $1.7 million, or 52.3%, to $4.9 million for the three months ended December 31, 2020, from $3.2 million for the three months ended December 31, 2019, largely due to the pandemic response. However, as a percentage of net sales, selling, general and administrative expenses decreased to 17.0% for the three months ended December 31, 2020, from 29.7% for the same period of 2019, primarily as a result of the growth in net sales.

Selling, general and administrative expenses increased by $4.8 million, or 36.1%, to $18.2 million for the year ended December 31, 2020, from $13.3 million for the year ended December 31, 2019, also largely due to the pandemic response. Again, however, as a percentage of net sales, selling, general and administrative expenses decreased to 17.7% for the year ended December 31, 2020, down from 28.6% for 2019, primarily as a result of the growth in net sales due to the pandemic.

Income from operations as a percentage of net sales for the three months ended December 31, 2020 was 31.2%, compared to 3.8% for the same period of 2019.

Income from operations increased by $28.6 million, or 945.1%, to $31.6 million for the year ended December 31, 2020, compared to $3.0 million for 2019.

Income from operations as a percentage of net sales for the year ended December 31, 2020 was 31.0%, compared to 6.5% for the same period of 2019.

Net Income

Net income for the three months ended December 31, 2020 was $7.4 million, compared to net income of $335,000 for the same period of 2019, representing an increase of $7.1 million, or 2,114%. The net income increase was due to an increase in income before provision for income taxes of $8.9 million, partially offset by an increase in provision for income taxes of $1.8 million. Net income as a percentage of net sales for the three months ended December 31, 2020 was 25.6%, and net income as a percentage of net sales for the three months ended December 31, 2019 was 3.1%.

Net income for 2020 significantly exceeded the Company’s previous net income record of $9.0 million for the year ended December 31, 2009, which resulted primarily from increased sales due to the H1N1 pandemic. Net income as a percentage of net sales for the year ended December 31, 2020 was 26.4%, and net income as a percentage of net sales for the year ended December 31, 2019 was 6.4%.
