Plexus (PLXS) Q4 2025 earnings review

Strong Finish to FY25, but Decelerating EPS Growth Signals Margin Headwinds Ahead

Plexus delivered a strong Q4, beating revenue and EPS guidance and capping a successful fiscal 2025 marked by 30% non-GAAP EPS growth and robust free cash flow of $154 million. The company's operational execution was excellent, highlighted by a five-year low in cash cycle days (63) and a record $941 million in new manufacturing program wins for the year. However, the outlook is mixed. While Q1 FY26 revenue guidance implies an acceleration in top-line growth to nearly 10% YoY, guided Non-GAAP EPS is flat year-over-year. This sharp deceleration in profitability growth points to significant margin pressure from increased investments and seasonal costs, overshadowing the positive revenue momentum.

๐Ÿ‚ Bull Case

Strong Wins & Share Gains

The company secured $941 million in annualized revenue from new program wins in FY25, and the funnel of qualified opportunities remains robust at $3.7 billion, providing good visibility for future growth.

Operational Excellence

Plexus generated $154 million in free cash flow in FY25, reduced gross inventory for the seventh consecutive quarter, and achieved a five-year best cash cycle of 63 days, demonstrating superb working capital management.

Shareholder Returns

The company returned $65 million to shareholders via buybacks in FY25 and has $85 million remaining on its current authorization, supported by a strong balance sheet that ended the year in a net cash position.

๐Ÿป Bear Case

Profitability Growth Stalls

The Q1 FY26 guidance for flat YoY Non-GAAP EPS marks a dramatic halt to the strong double-digit growth seen throughout FY25, indicating significant margin pressure from investments and operating costs.

Aerospace & Defense Weakness

The Aerospace & Defense segment was a notable laggard, with revenue declining 6% YoY in Q4 due to program ramp delays, underperforming the rest of the business.

Lower Free Cash Flow in FY26

Guidance for FY26 free cash flow of approximately $100 million represents a ~35% decline from the $154 million generated in FY25, reflecting higher investments in working capital and CapEx.

โš–๏ธ Verdict: โšช

Mixed. Plexus's operational execution is best-in-class, as evidenced by its strong cash flow and wins. However, the market looks forward, and the sharp deceleration in guided EPS growth is a significant concern. While revenue is set to accelerate, the inability to translate that into profit growth in the near term makes the story less compelling until margin expansion resumes.

Key Themes

CONCERN๐Ÿ”ด

EPS Growth Decelerates Sharply into FY26

The primary concern is the abrupt end to strong earnings growth. After growing Non-GAAP EPS by over 30% in FY25, Q1 FY26 guidance implies flat YoY performance ($1.735 midpoint vs $1.73 in Q1'25). This is despite a guided revenue acceleration to +9.6% YoY. Management attributes the pressure to increased investments in talent, technology, and facilities, alongside seasonal compensation costs, which will weigh on operating margins in the near term.

DRIVER๐ŸŸข๐ŸŸข

Exceptional Working Capital Management

Plexus continues to demonstrate elite operational control. The company reduced its gross inventory balance for the seventh consecutive quarter, down $82 million YoY. This discipline drove the cash conversion cycle down to 63 days, a five-year low and a 6-day sequential improvement. This efficiency was a key contributor to the strong $154 million in free cash flow for fiscal 2025.

DRIVER๐ŸŸข

Strong Wins Funnel Fuels Future Growth

The company's go-to-market engine remains strong, securing 141 new manufacturing wins in FY25 representing $941 million in annualized revenue. The funnel of qualified manufacturing opportunities grew to a robust $3.7 billion, with a record high value for Aerospace & Defense opportunities. This provides a solid foundation for growth beyond the modest end-market recovery.

CONCERN๐Ÿ”ด

Aerospace & Defense Segment Underperforms

Contradicting the narrative of broad strength, the Aerospace & Defense segment's revenue fell 6.0% YoY to $173 million, significantly lagging the company's overall +0.7% growth. Management attributed this to 'minor delays in the timing of new program ramps.' While the wins funnel for this segment is at a record high, the inability to convert it to revenue in Q4 is a point for monitoring.

DRIVER๐ŸŸข

Industrial Segment Rebounds on Semi-Cap Strength

The Industrial sector grew 11% sequentially, exceeding expectations, driven by increased demand from semiconductor capital equipment customers. Wins in the sector were at a 9-quarter high of $165 million, including substantial share gains with an existing semi-cap customer. This strength is offsetting otherwise muted demand in the broader industrial market.

THEME๐ŸŸข

Investing in Automation and AI Capabilities

Management highlighted ongoing investments in advanced capabilities. One win involved the assembly for an 'AI-powered digital cell analysis platform'. Internally, Plexus is deploying automation technologies, citing a warehouse pilot that resulted in a 300% increase in pick rate and a 60% reduction in space, with plans to roll this out to more sites in fiscal 2026. These investments are intended to drive long-term efficiency but are a contributing factor to near-term margin pressure.

Other KPIs

Free Cash Flow (FY25)$154 million

The company generated robust free cash flow, substantially exceeding initial projections. This was driven by strong operating performance and excellent working capital management. Guidance for FY26 is for a still-healthy ~$100 million, which will support CapEx of $90-$110 million and continued shareholder returns.

Annualized Revenue from New Wins (FY25)$941 million

Plexus secured 141 new manufacturing programs during the fiscal year. When fully ramped, these programs are expected to generate $941 million in annual revenue, supporting management's outlook for growth in excess of end markets in fiscal 2026.

Balance Sheet Position (25Q4)Net Cash

The company ended the fiscal year in a net cash position, with cash and equivalents of $306.5 million exceeding total debt and lease obligations of $137.8 million. This strong liquidity provides significant financial flexibility.

Guidance

Q1 FY26 Revenue$1.050 - $1.090 billion

Accelerating. The midpoint of $1.070 billion implies YoY growth of +9.6%, a significant acceleration from the +0.7% growth reported in Q4. This is driven by new program ramps and market share gains.

Q1 FY26 Non-GAAP Diluted EPS$1.66 - $1.81

Decelerating. The midpoint of $1.735 implies YoY growth of just +0.3%, a sharp deceleration from the +15.7% growth in Q4. This indicates that higher revenue will be fully offset by margin pressure from investments and seasonal costs.

Q1 FY26 Non-GAAP Operating Margin5.6% - 6.0%

Stable but compressing. The 5.8% midpoint is flat sequentially but down 20 basis points from 6.0% in Q1 FY25. Management expects to return to or exceed the 6% margin target as fiscal 2026 progresses.

FY26 Free Cash FlowApproximately $100 million

Decelerating. While still robust, this guidance is down from the $154 million generated in FY25. The decrease is attributable to higher working capital investments needed to support revenue growth and continued CapEx of $90-$110 million.

Key Questions

Margin Pressure vs. Revenue Growth

Your Q1 guidance implies a nearly 10-point spread between revenue growth and EPS growth. Can you help bridge this gap by quantifying the margin headwinds from strategic investments versus seasonal compensation costs, and outline the path back to achieving operating leverage in the second half of fiscal 2026?

Aerospace & Defense Conversion

The funnel of opportunities for Aerospace & Defense is at a record high, yet the segment's revenue declined 6% YoY in Q4. What specific actions are being taken to resolve program ramp delays, and what gives you confidence that you can convert this strong funnel to reverse the negative revenue trend in fiscal 2026?

Sustainability of Industrial Strength

The Industrial segment's rebound was heavily driven by semi-cap. How much of this performance is based on durable market share gains versus a potentially cyclical upswing in customer demand? What is your outlook for the non-semi-cap parts of the Industrial business?
