Management Comments

“Equipment demand for AI infrastructure was strong in the quarter and accounted for 35% of our Thermal Processing Solutions (TPS) segment revenue, up from 30% in the prior quarter,” commented Mr. Bob Daigle, Chief Executive Officer of Amtech. “Our book-to-bill ratio was 1.1 in the quarter, driven by AI applications with some deliveries stretching into Q3 to align with customer factory buildouts. We expect strength in demand for equipment powering AI applications to result in increased bookings on a sequential quarterly basis through the end of fiscal 2026."

"We are generating strong operating cash flow driven by high quality revenue streams, the cost structure improvements achieved over the last two years and improved collections in the quarter. The first quarter of fiscal 2026 marks the ninth consecutive quarter of positive operating cash flow. We ended the first quarter with $22.1 million of cash, up from $17.9 million in the prior quarter, with no debt. We believe growth opportunities driven by AI infrastructure investments and our differentiated capabilities combined with strong operating leverage that result from our asset-lite, semi-fabless business model position us well to deliver meaningful shareholder value.”

GAAP and Non-GAAP Financial Results

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

Net revenues decreased sequentially from the prior quarter, driven primarily by lower demand for silicon carbide polishing consumables that was partially offset by strong demand for reflow ovens used in AI applications. The decrease in net revenues as compared to the same period last year reflects these changes as well as lower demand for high-temperature belt furnaces and product line rationalization of diffusion furnaces which are part of the Thermal Processing Systems division. These declines versus the prior year were partially offset by higher AI-related revenues for advanced packaging and other thermal applications.

GAAP gross margin increased on a percentage basis but decreased by $0.3 million sequentially from the prior quarter and $0.9 million compared to the same prior year period due to the Company’s product line rationalization with a focus on growing higher margin product lines including its AI advanced packaging solutions. Gross margin as a percentage of sales increased to 44.8% in the fiscal 2026 first quarter from 38.4% in the same period of the prior year and 44.4% in the fiscal 2025 fourth quarter.

Selling, General & Administrative (“SG&A”) expenses increased $0.5 million sequentially from the prior quarter and decreased $1.2 million compared to the fiscal 2025 first quarter. The increase from the prior quarter is primarily due to incentive compensation, professional fees and insurance. The decrease from the prior year period is primarily due to cost reduction efforts and structural changes to reduce fixed costs.

Research, Development, and Engineering expenses increased by $0.3 million sequentially from the prior quarter and were relatively flat compared to the same period of the prior year. The increase from the prior quarter is primarily due to growth initiatives.

GAAP net income for the first quarter of fiscal 2026 was $0.1 million, or $0.01 per share. This compares to GAAP net income of $1.1 million, or $0.07 per share, for the preceding quarter, and GAAP net income of $0.3 million, or $0.02 per share, for the first quarter of fiscal 2025.

Unrestricted cash and cash equivalents at December 31, 2025, were $22.1 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.
