"I'm pleased to report that our third quarter performance was above expectations, with revenue of $19.6 million, an increase of 26% over the prior quarter. Both our Thermal Processing Solutions and our Semiconductor Fabrication Solutions segments exceeded forecasts, reflecting ongoing strength in the advanced packaging market and stabilizing demand within the mature-node semiconductor market. We have made significant progress optimizing our operating model over the past 18 months, resulting in $13 million in annualized savings. Looking ahead, we believe the structural changes we've made to improve operating leverage and our focused investments in product and application development position us well to deliver profitable growth in the years ahead," commented Mr. Bob Daigle, Chief Executive Officer of Amtech.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) See GAAP to non-GAAP reconciliation in schedules following this release.

Net revenues increased 26% sequentially from the prior quarter, driven primarily by strong demand in Asia for reflow ovens used in AI applications. Revenues decreased 27% compared to the same period last year, largely due to continued weakness in the mature node semiconductor market, which led to lower sales of wafer cleaning equipment, diffusion systems, and high-temperature furnaces. This decline was partially offset by increased sales of advanced packaging solutions.

GAAP gross margin increased by $9.5 million sequentially from the prior quarter, primarily due to the absence of $6.0 million in non-cash inventory write-downs recorded last quarter. Compared to the same period last year, gross margin decreased by $0.6 million, driven by lower sales volume resulting from continued weak demand in the mature node semiconductor market. This quarter's gross margin benefited from a $1.0 million Employee Retention Credit ("ERC") refund. Excluding the ERC, normalized gross margin was 41.5%, a solid improvement from 36.5% in the third quarter of fiscal 2024.

Selling, General & Administrative ("SG&A") expenses increased $0.3 million sequentially from last quarter and decreased $0.8 million compared to the same prior year period. The increase from last quarter is primarily due to an increase in third party consulting costs. The decrease compared to the same prior year period is primarily due to the ERC refund and cost reductions attributed to actions we have taken to reduce our fixed cost structure. We also saw lower commission expense from the reduced sales volume.

Research, Development, and Engineering expenses declined by $0.5 million quarter-over-quarter, primarily due to project-specific purchasing timing and the benefit of the ERC refund. Compared to the same period last year, expenses decreased $0.3 million, reflecting the ERC benefit and non-recurring development efforts within our Semiconductor Fabrication Solutions segment.

GAAP net income for the third quarter of fiscal 2025 was $0.1 million, or 1 cents per share. This compares to GAAP net loss of $31.8 million, or 2.23 cents per share for the preceding quarter and GAAP net income of $0.4 million, or 3 cents per share, for the third quarter of fiscal 2024.

Non-GAAP net income for the third quarter of fiscal 2025 was $0.9 million, or 6 cents per share. This compares to non-GAAP net loss of $2.3 million, or 16 cents per share for the preceding quarter and non-GAAP net income of $1.1 million, or 8 cents per share, for the third quarter of fiscal 2024.

------

Unrestricted cash and cash equivalents at June 30, 2025, were $15.6 million, compared to $11.1 million at September 30, 2024, due primarily to our focus on operational cash generation, strong accounts receivable collections from customers, and employee retention credit.

In discussing financial results for the three and nine months ended June 30, 2025 and 2024 and the three months ended March 31, 2025, in this press release, the Company refers to certain financial measures that are adjusted from the financial results prepared in accordance with United States generally accepted accounting principles ("GAAP"). All non-GAAP amounts exclude certain adjustments for stock compensation expense, severance expense, expenses related to the discontinued product line, gain on the sale of our Arizona headquarters, moving expenses, amortization of acquired intangible assets, acquisition expenses, goodwill and intangible asset impairment, inventory write-down of mature node semiconductor products, and income tax benefit related to our acquisition of Entrepix, Inc. A tabular reconciliation of financial measures prepared in accordance with GAAP to the non-GAAP financial measures is included at the end of this press release.

**Outlook**

Operating results can be significantly impacted, positively or negatively, by the timing of orders, system shipments, logistical challenges, and the financial results of semiconductor manufacturers. Additionally, the semiconductor equipment industries can be cyclical and inherently impacted by changes in market demand. Actual results may differ materially in the weeks and months ahead.

For the fiscal fourth quarter ending September 30, 2025, we expect revenues in the range of $17 to $19 million. Growth in AI related equipment sales in our Thermal Processing Solutions segment is anticipated to partially offset continued softness in mature node semiconductor product lines. With the benefit of previously implemented structural and operational cost reductions, we expect to deliver improved operating leverage, resulting in adjusted EBITDA margins in the mid-single digits. We remain focused on driving further efficiency gains and cost optimization across Amtech's operations, positioning the company to expand margins and generate more resilient profitability going forward.

A portion of Amtech's results is denominated in Renminbis, a Chinese currency. The outlook provided in this press release is based on an assumed exchange rate between the United States Dollar and the Renminbi. Changes in the value of the Renminbi in relation to the United States Dollar could cause actual results to differ from expectations.

**Conference Call**

Amtech Systems will host a conference call at 5:00 pm ET on Wednesday, August 6, 2025 to discuss our fiscal third quarter financial results. The call will be available to interested parties by dialing 1-800-717-1738. For international callers, please dial +1-646-307-1865.
