Management Comments

"AI related equipment demand continued to be very strong in the quarter and allowed us to deliver revenue that was up 8% sequentially and 31% year-over-year," commented Mr. Bob Daigle, Chief Executive Officer of Amtech. "Second quarter gross margin improved to 48%, an approximately 300 bps increase from the first quarter and an approximately 1100 bps increase from non-GAAP margins in the second quarter of 2025. These results continue to validate the strong operating leverage created by our initiatives to discontinue low margin product-lines and migrate to a semi-fabless manufacturing model over the past two years. The second quarter of fiscal 2026 marks the tenth consecutive quarter of positive operating cash flow.

"We are encouraged by the strong double-digit growth in recurring revenue streams we've generated from customer-centric growth initiatives in both of our business segments. This will continue to be an area of focus in addition to capitalizing on our differentiated equipment capabilities for advanced packaging and enterprise board assembly to support the enormous buildout of AI infrastructure. We are extremely well positioned to deliver meaningful shareholder value as we build on the strong financial foundation we've established to drive additional growth."

Net revenues increased 8% sequentially from last quarter and 31% from the second quarter of fiscal 2025. Both increases are primarily due to strong demand for reflow equipment used in AI applications. Over 20% of Thermal Processing Solutions revenue in the second quarter of 2026 is related to parts and services.

GAAP gross margin increased by $1.3 million sequentially compared to last quarter and increased by $10.1 million compared to the same prior year period. The increase in both periods is primarily due to the Company's product line rationalization, with a focus on growing higher-margin product lines, including AI-advanced packaging solutions. Gross margin as a percentage of sales increased to 47.7% in the fiscal 2026 second quarter from 44.8% in the fiscal 2026 first quarter and (2.1)% in the same period of the prior year.

During the second quarter of fiscal 2025, the Company recorded non-cash inventory write-downs driven by weak demand from mature-node semiconductor customers. In addition, $22.9 million was recorded for impairment charges, including $15.3 million in goodwill and $2.6 million in intangible asset impairment charges for the Semiconductor Fabrication Solutions segment, and $5.0 million in goodwill impairment charges for the Thermal Processing Solutions segment.

Selling, General & Administrative ("SG&A") expenses increased $0.3 million sequentially from the prior quarter and were relatively flat compared to the fiscal 2025 second quarter. The increase from the prior quarter is primarily due to expanding business activities, tax and IT consulting fees.

Research, Development, and Engineering expenses were relatively flat compared to the prior quarter and compared to the same period of the prior year.

GAAP net income for the second quarter of fiscal 2026 was $1.2 million, or $0.08 per share. This compares to GAAP net income of $0.1 million, or $0.01 per share, for the preceding quarter, and GAAP net loss of $31.8 million, or ($2.23) per share, for the second quarter of fiscal 2025. The Company's GAAP net income includes $0.3 million for foreign currency exchange losses in the second quarter of fiscal 2026, as compared to $0.2 million in the prior quarter, primarily driven by a weakening United States Dollar against the Chinese Renminbi.

Unrestricted cash and cash equivalents at March 31, 2026, were $24.4 million, compared to $17.9 million at September 30, 2025, due primarily to the Company's focus on operational cash generation, working capital optimization, strong accounts receivable collections from customers, and accounts payable management. This increase was partial offset by an additional $0.9 million in inventories to accommodate higher order flow.

Outlook

For the third fiscal quarter ending June 30, 2026, the Company expects revenues in the range of $20.5 to $22.5 million. With the benefit of previously implemented structural and operational cost reduction along with greater contributions from reoccurring sales, Amtech expects to deliver solid operating leverage, resulting in adjusted EBITDA margin in the low double digits.

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

Share Repurchase Program

On December 9, 2025, the Company's effectuated a share repurchase program for a period of one-year pursuant to which Amtech may purchase up to $5 million of its common stock. As of today, no shares were repurchased under the program.
