Management Comments

“Stronger than expected results in the fourth quarter were driven by AI applications,” commented Mr. Bob Daigle, Chief Executive Officer of Amtech. Advanced Packaging and assembly equipment we produce for AI infrastructure accounted for over 30% of our Thermal Processing Solutions (TPS) segment revenue in the quarter, up from about 25% in the prior quarter. Higher than expected revenue in both our TPS and Semiconductor Fabrication Solutions segments and the cost structure improvements we’ve made over the past 18 months resulted in adjusted EBITDA margins above 10% for the quarter. I am also pleased to report our eighth consecutive quarter of positive operating cash flow. We eliminated our debt last year and ended the fiscal year with nearly $18 million of cash, up from $11 million at the end of the prior year. Our focused growth strategy and strong operating leverage position us well to deliver meaningful shareholder value."

GAAP and Non-GAAP Financial Results

Net revenues increased sequentially from the third quarter, driven primarily by strong demand in Asia for reflow ovens used in AI applications. The decrease in net revenues compared to the same period last year reflects higher AI-related revenues offset by substantially lower mature node semiconductor revenues primarily for sales of wafer cleaning equipment and parts in our Semiconductor Fabrication Solutions segment. In our Thermal Processing Solutions segment diffusion furnaces, and high-temperature furnaces drove the decline in sales.

GAAP gross margin decreased by $0.3 million sequentially from the prior quarter and decreased $1.0 million compared to the same prior year period. The decrease from the prior quarter was due to the Employee Retention Credit (ERC) received in the third quarter of 2025. The decrease in gross margin from the same prior year period is primarily due to lower sales volume in the mature node semiconductor market. Gross margin as a percentage of sales increased from 40.7% in the same prior year period up to 44.4% this current year quarter driven by cost save initiatives and product mix. Excluding the ERC one-time credit, gross margin would have been 41.5% for the third quarter.

Selling, General & Administrative (“SG&A”) expenses decreased $1.0 million sequentially from the prior quarter and decreased $2.4 million compared to the same prior year period. The decrease from prior quarter and the same prior year period is primarily due to cost reduction efforts around overhead expenses and cost structure changes to reduce fixed costs.

Research, Development, and Engineering expenses increased by $0.2 million sequentially from prior quarter and decreased $0.4 million compared to the same prior year period. The increase from the prior quarter is primarily due to growth initiatives and the decrease compared to the same prior year period is primarily due to a more focused approach to innovative investments.

GAAP net income for the fourth quarter of fiscal 2025 was $1.1 million, or $0.07 cents per share. This compares to GAAP net income of $0.1 million, or $0.01 cents per share, for the preceding quarter, and GAAP net loss of $0.5 million, or $0.04 cents per share, for the fourth quarter of fiscal 2024.

Non-GAAP net income for the fourth quarter of fiscal 2025 was $1.4 million, or $0.10 cents per share. This compares to non-GAAP net income of $0.9 million, or $0.06 cents per share, for the preceding quarter, and non-GAAP net loss of $7,000, or $0.0 cents per share, for the fourth quarter of fiscal 2024.

Unrestricted cash and cash equivalents at September 30, 2025, were $17.9 million, compared to $11.1 million at September 30, 2024, due primarily to the Company's focus on operational cash generation, working capital optimization, strong accounts receivable collections from customers, accounts payable management, and employee retention credit.

In discussing financial results for the three and twelve months ended September 30, 2025 and 2024 and the three months ended June 30, 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 the Company's 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 first fiscal quarter ending December 31, 2025, the Company expects revenues in the range of $18 to $20 million. AI related equipment sales for the 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, Amtech expects to deliver solid operating leverage, resulting in adjusted EBITDA margins in the high single digits. Amtech remains focused on driving further efficiency gains and cost optimization across all operations, positioning the Company to expand margins and generate more consistent 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.

Share Repurchase Program

The Company also announced today that its Board of Directors has authorized a share repurchase program pursuant to which Amtech may purchase up to $5 million of its common stock in the open market or in privately negotiated transactions, including accelerated share repurchase transactions, block trades or pursuant to Rule 10b5-1 trading plans. The repurchase program has been authorized for a period of one-year, effective December 10, 2025.
