PRO-DEX, INC. ANNOUNCES FISCAL 2021

FOURTH QUARTER AND FULL-YEAR RESULTS

IRVINE, CA, August 26, 2021 - PRO-DEX, INC. (NasdaqCM: PDEX) today announced financial results for its fiscal 2021 fourth quarter and full-year ended June 30, 2021.

Quarter Ended June 30, 2021

Net sales for the three months ended June 30, 2021 decreased $1.7 million, or 15%, to $9.4 million from $11.1 million for the three months ended June 30, 2020, due primarily to decreased medical device sales. This is due to two product launches in the prior fiscal year which had high initial sales volumes, which is typical, as our customers generally order in higher volumes in the beginning of a product introduction. Also, six to twelve months following launch our customers typically begin reordering these products on a quarterly basis and these orders continue to help facilitate our year-over-year growth. Gross profit for the three months ended June 30, 2021 decreased $1.2 million, or 27%, to $3.1 million from $4.3 million for the same period in 2020. The decrease in gross margin is due to a decline in 4^th quarter sales of the two aforementioned product launches, as well as price concessions to our largest customer, coupled with under-absorption of our fixed costs resulting, in part, from lower sales volumes.

Operating expenses (which include selling, general and administrative, and research and development expenses) for the quarter ended June 30, 2021 increased 21% to $2.5 million from $2.1 million in the prior year’s corresponding quarter, due primarily to increased expenditures of $385,000 in research and development costs to support our continued efforts to further grow our business.

Net income for the quarter ended June 30, 2021 decreased by $1.7 million to $0.9 million, or $0.22 per diluted share, compared to $2.5 million, or $0.64 per diluted share, in the corresponding quarter in 2020.

Year Ended June 30, 2021

Net sales for the fiscal year ended June 30, 2021 increased $3.2 million, or 9%, to $38.0 million from $34.8 million for the fiscal year ended June 30, 2020, due primarily to increases in medical device revenues. Specifically, we generated an increase in sales of $4.8 million in fiscal 2021 over fiscal 2020 due to the new thoracic driver we launched to our second largest customer in the prior fiscal year, much of which represented the fulfillment of their initial launch orders.

Gross profit for the fiscal year ended June 30, 2021 increased $0.4 million, or 3%, to $13.6 million compared to $13.1 million for fiscal 2020, due to increased revenues.

Operating expenses (which include selling, general and administrative, and research and development expenses) for the fiscal year ended June 30, 2021 increased 49% to $9.1 million from $6.1 million in the prior fiscal year. Of the total increase in operating expenses, $887,000 relates to an increase in general and administrative expenses primarily due to increased non-cash stock compensation expense in the amount of $615,000 as well as $267,000 in expenses related to our newly acquired commercial building. Our $2.1 million increase in research and development costs from fiscal 2020 to fiscal 2021 reflects our continued investment in new product development as well as our commitment to continuous improvement of our existing products.

Net income for the fiscal year ended June 30, 2021 was $4.5 million, or $1.13 per diluted share, compared to $6.1 million, or $1.50 per diluted share, for fiscal 2020.

Although we have released our earnings prior to our Annual Report on Form 10-K with the Securities and Exchange Commission, we are able to do this because we are a non-accelerated filer and as a result have more time to do so at fiscal year-end. During our quarterly reporting periods, we anticipate that our earnings releases will continue to be released at the same time as our Form 10-Q’s are filed with the Securities and Exchange Commission. We anticipate filing our Form 10-K with the Securities and Exchange Commission on September 9, 2021.

Guidance

Pro-Dex typically does not provide sales, earnings, or other guidance, and while the COVID-19 pandemic did not materially adversely affect our financial results in our fiscal year ended June 30, 2021, we did experience under-absorbed manufacturing costs, due in part from compensated absences related to COVID-19, a portion of which we expect to recover from amended payroll tax returns, as prescribed by the Families First Coronavirus Response Act. Additionally, during calendar 2021, we began to see some challenges in our supply chain in the form of delayed shipments, longer lead times, and surcharges, much of which our suppliers indicate have been caused by the pandemic. If any of these conditions persist or are exacerbated in the future, we could be negatively impacted. We have and continue to implement plans and processes to mitigate these challenges that many manufacturers similarly face. Our prospects remain positive with additional capacity forthcoming to allow for continued sales growth through our aggressive product development efforts.

CEO Comments

“We are very pleased with our continued year-over-year sales growth, as well as the progress we have made in readying our new building for move-in.” said the Company’s President and Chief Executive Officer Richard L. (“Rick”) Van Kirk. “While we are unable to predict the total impact of the COVID-19 pandemic, we remain vigilant in our efforts to provide a safe workplace for our employees, excellent service to our customers, and continue to focus on strategic investments in plant and equipment and product development efforts to continue to grow our business. With our new building and additional capacity coming online this year, combined with our focus on new business development and technology, we are excited about fulfilling the potential of the new building and growing our business significantly for years to come.”

R&D Projects

The amount spent on projects under development is summarized below (in thousands):

As we introduce new products into the market, we expect to see an increase in sustaining and other engineering expenses. Typical examples of sustaining engineering activities include, but are not limited to, end-of life component replacement, especially in electronic components found in our PCB assemblies, analysis of customer complaint data to improve process and design, replacement and enhancement of tooling and fixtures used in our machine shop, assembly operations and inspection areas to improve efficiency and through-put. Additionally, these costs include development projects that may be in their infancy and may or may not result in a full-fledged product development effort.
