PLXS Stock Up 32% in 3 Months: Is There Further Upside Left?

The S&P 500 composite and the broader Computer Technology Sector have declined 4.8% and 6.7%, respectively.

Other players in the electronics manufacturing services space, like Jabil JBL and Flex Ltd. FLEX, have gained 13.1% and 3.5%, respectively, while Sanmina Corporation SANM is down 14.8%.

Given this backdrop, the question for investors is straightforward: after this rally, does PLXS still offer compelling long-term upside?

Let us take a closer look at PLXS fundamentals, growth drivers, competitive advantages and potential risks and assess whether it is still a buy?

Multiple Tailwinds Offer Runway for Long-Term Growth

A healthy number of program ramps are expected to drive the top-line performance for Plexus. The company is focusing its efforts on sectors with robust demand, such as healthcare and life sciences, aerospace and defense, and industrial markets, especially semicap and energy management subsectors.

In the first quarter of fiscal 2026, Plexus announced 22 manufacturing program wins, which are estimated to contribute $283 million in annualized revenues once fully ramped into production. For fiscal 2025, Plexus had 141 manufacturing wins totaling $941 million in annualized revenues.

Notably, the Aerospace and Defense sector delivered record $220 million in the fiscal first quarter wins and Healthcare/Life Sciences had $40 million. Management highlighted that program wins, share gains and strengthening market demand position it for meeting/exceeding the high end of 9% to 12% total revenue growth target for fiscal 2026. The funnel of qualified manufacturing opportunities is $3.6 billion, indicating a strong pipeline for growth. The company had a record funnel for its Aerospace and Defense end market segment.

For both Aerospace and Healthcare/Life Sciences segments, PLXS expects to exceed the 9-12% range.

Further, strong cash flow generation bodes well. Plexus is driving free cash flow generation through a combination of operational/capex discipline and inventory reduction. While fiscal first-quarter free cash flow was negative due to investments, Plexus reaffirmed its fiscal 2026 free cash flow target of $100 million, underscoring working capital efficiency. Strong cash flow generation positions Plexus to maximize shareholder value via buybacks and reduce debt. It repaid $100 million of debt in fiscal 2025.

On the last earnings call, management emphasized that all excess cash will be used to create shareholder value. The company repurchased $22.4 million worth of shares at an average price of $146.36 per share under its repurchase program. Out of the $100 million authorization, $62.6 million remains available. For fiscal 2025, it repurchases $65 million worth of shares. The robust cash generation ensures that Plexus has a healthy financial foundation to support growth and investment in the business.

The company’s business strategy, focusing on earning a return on invested capital (“ROIC”) that exceeds its weighted average cost of capital (“WACC”), bodes well. For the first quarter of fiscal 2026, the company’s after-tax ROIC reached 13.2%, 420 bps above the WACC of 8.9%.

However, no investment case is without risks. The challenges in the Industrial sector in the near term remain concerning. Fiscal first-quarter revenues declined 8% sequentially. Growth recovery is heavily dependent on semicap demand rebound and program ramps in the industrial equipment subsector, while other industrial subsectors continue to face softness. If the semicap cycle stalls or weakens again, the Industrial segment could remain a drag on consolidated growth. Management expects fiscal 2026 revenues for this sector to approach the 9% to 12% target range.

Macro uncertainty owing to shifting trade policy and stiff competition in the EMS space from FLEX, Jabil and Sanmina are additional concerns.

Given all these factors, analysts have revised PLXS’ estimates up for the current quarter and year.

PLXS Valuation

How to Play PLXS Stock?

Plexus’ robust pipeline of program wins, expanding exposure to end markets like aerospace, defense and healthcare, and a solid $3.6 billion opportunity funnel provide improved visibility into sustained revenue growth. Coupled with healthy cash generation supporting buybacks, PLXS remains well-positioned for further upside despite near-term industry headwinds.
