StockStory’s Take

Plexus delivered results in Q3 that were in line with market expectations, with management attributing the flat year-on-year revenue to the timing of new program ramps and minor delays in its aerospace and defense segment. CEO Todd Kelsey highlighted that late-quarter demand from semi-capital equipment and energy customers offset these delays, while the company’s strong free cash flow performance benefited from ongoing efforts to reduce working capital. Management also noted operational improvements, particularly in inventory management and automation, as drivers of stable operating margins.

Looking ahead, Plexus’s guidance reflects optimism around new manufacturing program ramps and continued market share gains, particularly in defense, semi-cap, and healthcare sectors. Management expects ongoing investments in technology, facilities, and talent to support both efficiency and future growth. Kelsey stated, “We expect to deliver revenue growth through ongoing new program ramps, inclusive of market share gains,” but also acknowledged that incentive compensation and ramp-up costs at new facilities could temporarily pressure margins.

Key Insights from Management’s Remarks

Management pointed to new program wins, sector-specific growth, and operational execution as key drivers for the quarter and the guidance.

• New program ramps: Plexus secured 28 new manufacturing programs in the quarter, which are expected to generate $274 million in annual revenue when fully ramped. These wins spanned commercial aerospace, unmanned aircraft, and healthcare.
• Sector performance differentiation: The semi-capital equipment and energy subsectors saw late-quarter demand strength, while aerospace and defense experienced minor delays in new program transitions. Healthcare/life sciences benefited from ongoing product ramps and improved customer demand.
• Operational efficiency initiatives: Management emphasized ongoing automation and productivity improvements, such as warehouse automation and machine optimization, which contributed to lower inventory and improved working capital.
• Facility expansion and investments: The new Penang, Malaysia site began ramping, and management expects it to reach corporate profitability within two quarters. Investments also targeted IT infrastructure for compliance and operational enhancements.
• Strong free cash flow and capital returns: The company generated $97 million in free cash flow for the quarter and continued to reduce debt while returning cash to shareholders through share repurchases, reflecting disciplined capital management.

Drivers of Future Performance

Plexus expects program ramps, sector-specific growth, and continued operational investments to drive results in the coming quarters, but acknowledges margin headwinds from incentive compensation and expansion costs.

• Program ramp momentum: Management anticipates that ongoing and new program ramps in sectors such as defense, semi-cap, and healthcare will support revenue growth above end market averages. These wins are expected to offset muted industrial demand.
• Margin management challenges: While aiming for a 6% non-GAAP operating margin, Plexus expects higher incentive compensation and upfront costs from facility expansions, particularly in Penang, to create near-term margin pressure. However, automation and productivity gains are projected to improve margins as the year progresses.
• Capital allocation priorities: The company plans to maintain capital spending in the $90–$110 million range, focusing on automation and operational efficiency rather than new site construction, which should enhance revenue capacity and operational leverage long term.

Catalysts in Upcoming Quarters

In the upcoming quarters, the StockStory team will focus on (1) the pace and profitability of new program ramps in defense, semi-cap, and healthcare, (2) margin trends amid ongoing investments and incentive costs, and (3) the effectiveness of automation and operational efficiency initiatives in driving working capital improvement. Additional signals will include any acceleration in commercial aerospace demand and updates on large-scale facility utilization.

Plexus currently trades at $149.76, up from $145.88 just before the earnings. Is there an opportunity in the stock?The answer lies in our full research report (it’s free for active Edge members).
