Risks

• 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.
• The semiconductor equipment industries are cyclical and inherently impacted by changes in market demand.
• Forward-looking information and statements are subject to risks, uncertainties, and contingencies, including changes in price and volume and the volatility of common stock.
• Adverse developments affecting either or both of prices and trading of exchange-traded securities, including securities listed on the Nasdaq Global Select Market.

• Changes in the value of the Renminbi in relation to the United States Dollar could cause actual results to differ from expectations, as a portion of results is denominated in Renminbis.

Future Outlook

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 are anticipated to partially offset continued softness in mature node semiconductor product lines. With the benefit of previously implemented structural and operational cost reductions, the company expects to deliver solid operating leverage, resulting in adjusted EBITDA margins in the high single digits. The company remains focused on driving further efficiency gains and cost optimization across all operations to expand margins and generate more consistent profitability going forward.

Management Comments

• "Stronger than expected results in the fourth quarter were driven by AI applications."
• "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."
