Executive Summary

Q4 FY2024 revenue was $24.1M with GAAP EPS of $(0.04) and non-GAAP EPS of $0.00; gross margin expanded to 40.7% from 36.5% in Q3 and 10.1% in Q4 FY2023, driven by mix and cost actions .
The quarter marked a fourth consecutive period of positive adjusted EBITDA ($0.8M) and operating cash flow; Amtech ended FY2024 debt-free with $11.1M cash and $10.8M net cash after ~$4M of debt repayment in Q4 .
Orders and backlog declined sequentially (orders $17.6M; backlog $25.3M), indicating near-term revenue pressure as non‑AI end markets remain weak; management guided Q1 FY2025 revenue to $21–$24M and adjusted EBITDA ~nominally positive/neutral (press release vs call wording) .
Strategic pivot toward higher-margin recurring revenue (consumables, parts, services) continued; PR Hoffman consumables rose 28% y/y and segment branding was updated to reflect a front-end “Semiconductor Fabrication Solutions” and back-end “Thermal Processing Solutions” focus, including AI data center packaging opportunities .

What Went Well and What Went Wrong

What Went Well
- Margin execution and cost reduction: gross margin reached 40.7% in Q4 (from 36.5% in Q3) as mix and cost saves flowed through; ~$7M annual structural savings with a further ~$2M operational savings targeted by mid-FY2025 .
- Recurring revenue momentum: PR Hoffman consumables rose 28% y/y; company emphasized growth in consumables, parts, and services to drive less-cyclical margins and cash flow .
- Balance sheet de-risked: generated positive adjusted EBITDA and operating cash flow for a fourth straight quarter and fully repaid remaining debt; exited Q4 with $11.1M cash and $10.8M net cash .
What Went Wrong
- Demand softness outside AI: sequential revenue declined 10% to $24.1M, with continued weakness in diffusion/reflow/wafer cleaning equipment not tied to AI infrastructure .
- Orders/backlog trend: new orders fell to $17.6M and backlog to $25.3M (from $18.8M and $31.8M in Q3, and $19.8M and $44.3M in Q2), signaling near-term pressure .
- Mixed guidance tone: Q1 FY2025 guide calls for $21–$24M revenue and adjusted EBITDA “nominally positive” in the press release vs “nominally neutral” on the call—highlighting conservatism and a still-challenging macro .

Management Commentary

“We’ve made significant progress… delivering positive operating cash flow across all segments… [and] $4 million of adjusted EBITDA profit… $7 million of annualized operating savings” .
“We… exited from the unprofitable legacy equipment business at PR Hoffman, and [shifted to] consumables… sales… surged by 28% year-over-year” .
“Within our BTU business… shift to a hybrid manufacturing model… by the middle of the next fiscal year, we expect to realize approximately $2 million in additional operational savings above the $7 million” .
“We have renamed our business segments… Semiconductor Fabrication Solutions… and Thermal Processing Solutions… with an emphasis on applications that support AI data centers” .
“We managed to maintain positive adjusted EBITDA and reduce working capital to pay off our debt and end the year with a cash balance in excess of $11 million” .

Q&A Highlights

AI and advanced packaging pipeline: Management highlighted reflow equipment used “extensively” in advanced packaging and early-stage consumables work in thermal management for high-heat AI chips; the goal is to “broaden” AI exposure beyond back-end equipment .
Silicon carbide (SiC) consumables: PR Hoffman consumables grew 28% y/y, “a lot of that… related to silicon carbide”; EV demand expectations tempered but offset by other SiC applications, maintaining optimism for SiC growth .
Cash/debt: Q4 cash decline was due to ~$4M debt paydown; “we wanted to be debt-free… and we’re done, no more debt” .
Margin outlook: Given Q1 mix, margins are expected just under Q4, then “right in that range of 40%” with further contract manufacturing benefits as volume recovers .
R&D cadence: Return to a “normal run rate” around ~$1M per quarter after timing-driven Q3/Q4 shifts .

Estimates Context

Street consensus from S&P Global was unavailable at query time due to a system limit, so we cannot quantify beats/misses for Q4 FY2024 or Q1 FY2025 guidance versus consensus. Consensus estimates from S&P Global were unavailable at the time of request.
Directionally, Q1 FY2025 revenue guidance of $21–$24M implies a sequential decline from Q4’s $24.1M at the midpoint, suggesting expectations may need to reflect ongoing softness outside AI-related demand .

Key Takeaways for Investors

Margin/FCF discipline is working: Q4 GM reached 40.7% with a fourth consecutive positive adjusted EBITDA; structural ($7M) plus targeted additional ($2M) savings underpin margin durability through the cycle .
De-risked balance sheet: Debt fully repaid; net cash of $10.8M provides optionality amid a weak capex cycle and supports the pivot to recurring, higher-margin revenue .
Near-term pressure evident: Orders and backlog fell again (orders $17.6M; backlog $25.3M), and Q1 FY2025 revenue guidance of $21–$24M signals continued softness outside AI infrastructure .
AI advanced packaging is the growth vector: Reflow tools serve advanced packaging; management is adding consumables exposure in thermal management for AI chips—potential catalysts as OSAT/OEM utilization rises .
Recurring revenue strategy gaining traction: PR Hoffman consumables +28% y/y; consolidating front-end consumables and services under one leadership should drive mix and reduce cyclicality .
Watch the margin narrative: Management targets ~40% GM as a “new normal” with mix and outsourcing—sustaining this through lower revenue quarters will be a critical stock narrative driver .
Guidance language nuance: Press release guided Q1 adjusted EBITDA “nominally positive” vs “nominally neutral” on the call—underscores conservatism and the importance of mix/order timing near term .

Appendix: Additional Context and Non-GAAP Adjustments

Q4 FY2024 non-GAAP excludes stock comp, severance, discontinued product line expenses, gain on HQ sale, amortization, acquisition expenses, and tax effects; Q4 FY2023 had large intangible impairment ($4.6M) and inventory write-downs ($1.5M) that depressed gross margin to 10.1% .
Q3 FY2024 press release reiterated $7M annualized savings and provided Q4 FY2024 guide of $22–$25M revenue with adjusted EBITDA nominally positive, which proved in line with actuals (revenue $24.1M; adj. EBITDA $0.83M) .
Scheduling press release: Company pre-announced the Q4 FY2024 report and call for December 9, 2024 (for completeness) .
