Sanmina (SANM) Q3 2025 earnings review
Execution Drives Strong Beat and Raise; Transformative ZT Acquisition Progresses
Sanmina delivered a strong Q3, exceeding expectations on Revenue ($2.04B vs. $1.975B guided midpoint) and Non-GAAP EPS ($1.53 vs. $1.40 guided midpoint). YoY revenue growth accelerated to 11%, driven by a 19% surge in the Communications & Cloud segment and a standout performance in the Components (CPS) segment, where gross margins hit a record 14.7%. Strong operational execution and working capital discipline generated an impressive $168M in free cash flow. While the Q4 guidance implies a tougher YoY comparison, the company continues to progress towards closing the transformative acquisition of ZT Systems' manufacturing business by the end of calendar 2025.
🐂 Bull Case
Revenue and EPS growth are accelerating, driven by broad-based demand, particularly in the Communications & Cloud segment which grew 19% YoY.
The high-value Components (CPS) segment achieved a record 14.7% gross margin, showcasing strong operational leverage and a favorable product mix.
The pending acquisition of ZT Systems is set to double revenue and establish Sanmina as a key end-to-end player in the high-growth data center and AI infrastructure market.
🐻 Bear Case
Q4 guidance implies a sharp deceleration in YoY revenue growth to just 1.6%, raising questions about near-term momentum despite positive commentary.
Integrating the ZT Systems business, which is nearly the size of Sanmina's current revenue, presents significant execution and financial risk.
Management continues to flag ongoing risks from tariffs and the broader geopolitical landscape, which could impact customer demand.
⚖️ Verdict: 🟢
Bullish. The core business is executing exceptionally well, with accelerating growth and expanding margins. While the Q4 guidance is conservative and ZT integration is a major task, the strategic repositioning and current operational momentum are highly compelling. The slowdown in guidance appears to be more a function of a tough comparison than a crack in the business fundamentals.
Key Themes
Communications & Cloud Infrastructure Powers Growth
The Communications Networks and Cloud Infrastructure segment remains the primary growth engine, with revenue surging 19.1% YoY to $786 million. Demand is robust for high-performance routers, switches, and advanced optical systems needed to support data center and AI build-outs. Management sees continued positive trends and is investing to expand its end-to-end capabilities for this market.
Components (CPS) Segment Hits Record Profitability
A key positive surprise was the CPS segment's performance, where non-GAAP gross margin jumped to a record 14.7%, a 320 basis point improvement YoY. This signals a significant turnaround from prior quarters that were impacted by program delays, and it demonstrates strong operational leverage and a favorable shift in product mix toward higher-value components.
Disciplined Working Capital Management Boosts Cash Flow
Sanmina generated $168 million in free cash flow, driven by strong earnings and excellent working capital control. Inventory turns improved significantly to 6.3x from 5.1x a year ago, while net inventory dollars fell 12% YoY despite 11% revenue growth. This efficiency provides ample flexibility for strategic investments and continued shareholder returns.
Guidance Implies Sharp Revenue Deceleration
A key concern is the contradiction between the positive narrative and the forward-looking data. The Q4 revenue guidance midpoint of $2.05B implies only 1.6% YoY growth, a stark slowdown from Q3's 10.9%. While management points to a tougher comparison period, this abrupt deceleration warrants close monitoring as a potential sign of slowing demand.
Strategic Transformation via ZT Systems Acquisition
The pending acquisition of ZT Systems' manufacturing business is the company's most significant strategic move, positioning it to capitalize on long-term growth in data center and AI infrastructure. The deal is expected to add $5-6 billion in annual revenue, effectively doubling the company's size and shifting its focus toward higher-value, full system integration for hyperscale customers. Regulatory approvals are on track for a close near the end of calendar 2025.
Macro and Geopolitical Risks Persist
Management continues to cite tariffs and the global geopolitical landscape as sources of uncertainty. While the company's global footprint allows it to help customers mitigate these issues, and costs are typically passed through, the risk of a broader impact on end-market demand remains a key concern for the entire electronics manufacturing industry.
Other KPIs
The company generated robust free cash flow, marking a significant acceleration from prior quarters. Year-to-date free cash flow now stands at $341 million, easily funding the $114 million in share repurchases while strengthening the balance sheet. This highlights strong earnings quality and operational efficiency.
Both segments showed accelerating YoY growth. The larger IMS segment grew 11.6% to $1.65B with a solid 7.5% gross margin. The CPS segment grew 8.8% to $422M, but its standout feature was the record 14.7% gross margin, which was a primary driver of the corporate-level earnings beat.
Guidance
Decelerating. The guidance implies a significant slowdown in top-line momentum. At the midpoint, revenue is guided to grow just 1.6% YoY, a sharp drop from 10.9% in Q3. Profitability remains strong, with implied Non-GAAP EPS growth of 9.8% YoY. The revenue deceleration is attributed to a much tougher comparison against Q4'24, which was a strong recovery quarter in the prior year.
