PRO-DEX, INC. ANNOUNCES FISCAL 2025

FOURTH QUARTER AND FULL-YEAR RESULTS

IRVINE, CA, September 4, 2025 - PRO-DEX, INC. (NasdaqCM: PDEX) today announced financial results for its fiscal 2025 fourth quarter and full-year ended June 30, 2025.

Quarter Ended June 30, 2025

Net sales for the three months ended June 30, 2025 increased $2.5 million, or 16%, to $17.5 million from $15.0 million for the three months ended June 30, 2024, due primarily to increased revenue to our top three customers. Gross profit for the three months ended June 30, 2025 decreased $599,000, or 15%. Our gross margin decreased from 27% for the three months ended June 30, 2024, to 20% for the three months ended June 30, 2025, due to unfavorable product mix, and higher indirect manufacturing costs including the initial wave of tariff costs. During much of the fourth quarter we were shipping our largest customer their legacy product but, late in the fourth quarter, we resumed production and shipment of their next generation handpiece as they released their product hold and returned us to full production.

Operating expenses (which include selling, general and administrative, and research and development expenses) for the quarter ended June 30, 2025, increased $409,000 to $2.1 million, compared to $1.7 million for the prior fiscal year’s corresponding quarter. We have increased selling expenses by $96,000, general and administrative expenses by $244,000 and engineering expenses by $69,000 for the quarter ended June 30, 2025, compared to the corresponding quarter in 2024. Increases relate primarily to increased personnel costs in each of these areas to support our continued growth.

Our operating income for the quarter ended June 30, 2025, decreased $1.0 million, or 43%, to $1.3 million compared to $2.3 million for the prior fiscal year’s corresponding quarter. The decrease reflects our decreased gross profit and higher operating expenses, as described above.

Net income for the quarter ended June 30, 2025, decreased by $391,000 to $1.2 million, or $0.36 per diluted share, compared to $1.6 million, or $0.46 per diluted share, in the corresponding quarter in 2024.

Year Ended June 30, 2025

Net sales for the fiscal year ended June 30, 2025 increased $12.8 million, or 24%, to $66.6 million from $53.8 million for the fiscal year ended June 30, 2024, due primarily to increases in revenue from our largest customer. Specifically, the increase relates to $12.0 million in sales of the next generation handpiece to that same customer.

Gross profit for the fiscal year ended June 30, 2025, increased $5.0 million, or 34%, to $19.5 million compared to $14.5 million for fiscal 2024. Our gross margin increased from 27% in fiscal 2024 to 29% in fiscal 2025, due to overall favorable product mix (notwithstanding the unfavorable product mix during the fourth quarter described above).

Operating expenses (which include selling, general and administrative, and research and development expenses) for the fiscal year ended June 30, 2025, increased $1.4 million or 20% to $8.8 million from $7.4 million in the prior fiscal year. The increase relates primarily to an increase in personnel costs in selling, and general and administrative expenses to support our continued growth. The increase in research and development expenses in fiscal 2025 is primarily related to an increase in internal product development projects compared to fiscal 2024.

Our operating income for the year ended June 30, 2025, increased $3.5 million, or 49%, to $10.7 million compared to $7.2 million for the prior fiscal year’s corresponding quarter. The increase reflects our increased sales and gross profit, as described above.

Net income for the fiscal year ended June 30, 2025, was $9.0 million, or $2.67 per diluted share, compared to $2.1 million, or $0.60 per diluted share, for fiscal 2024. Our net income for the year ended June 30, 2025, contains unrealized gains on our marketable equity investments of $1.5 million while our net income for the year ended June 30, 2024, contains unrealized losses on our marketable equity investments of $4.1 million. The difference in the growth rate of net income and operating income is primarily due to unrealized gains and losses of investments. All of our investments are recorded at estimated fair value, and the valuation can be highly volatile.

CEO Comments

“We are very pleased with our fiscal 2025 performance including increasing sales by 24% and an increase of $3.5 million in operating income.” said the Company’s President and Chief Executive Officer Richard L. (“Rick”) Van Kirk. “While this fiscal year included disruption in transitioning to our largest customer’s next generation handpiece, we continued to meet our customers’ requests by nimbly shifting assembly schedules to their requested mix of legacy and new product.” Mr. Van Kirk continued, “Additionally, we expect fiscal 2026 to continue our trend of revenue and operating income growth, especially as evidenced by our June 30^th backlog in the amount of $50.4 million. We have also begun working with customers on sharing of tariff costs and are also excited about added depth in our management team and improvements being made to our manufacturing systems.”
