(NASDAQ: PLXS), the Wisconsin-based electronics manufacturing services company, reported record fiscal third-quarter 2026 revenue of $1.305 billion and now expects mid-teens or greater revenue growth for fiscal 2026. That is a sharp change from its earlier 9% to 12% growth goal—but the full-year figure is guidance, not a result. Whether the acceleration lasts depends on turning new program wins into profitable production, sustaining demand in cyclical markets, and converting revenue into cash.
What Plexus does—and which Plexus this is
This is Plexus Corp., not Plexus Worldwide, the wellness direct-selling company. Plexus Corp. designs, manufactures and services complex products for other businesses. Its customers rely on it to help bring products to market and produce them at scale. The company serves markets that it identifies as aerospace and defense, healthcare and life sciences, and industrial. Plexus’s fiscal 2025 Form 10-K describes its business and market context.
That business model makes program execution central to the growth story. Winning a manufacturing program is not the same as booking all the revenue it may eventually generate: production must ramp, and the work must be delivered at acceptable margins.
What changed in fiscal 2026
In its July 29, 2026 release, Plexus reported fiscal Q3 revenue of $1.305 billion. The company also raised its full-year expectation: management now anticipates mid-teens or greater fiscal 2026 revenue growth, compared with its earlier goal of 9% to 12% stated after fiscal 2025. The change reflects a more optimistic outlook, not a revision to already reported annual results.

| Measure | Reported result or outlook | Basis |
|---|---|---|
| Fiscal Q3 2026 revenue | $1.305 billion | Reported result |
| Fiscal Q4 2026 revenue | $1.330 billion to $1.380 billion | Company guidance |
| Fiscal 2026 revenue growth | Mid-teens or greater | Management outlook |
| Earlier fiscal 2026 growth goal | 9% to 12% | Goal stated after fiscal 2025 |
The Q4 range and full-year growth expectation came from Plexus’s July 29, 2026 results release. CEO Todd Kelsey said the company expected “mid-teens or greater fiscal 2026 revenue growth, with robust operating performance,” describing management’s forecast rather than a guaranteed outcome.
The acceleration follows a relatively flat prior year. Fiscal 2025 revenue was $4.033 billion, compared with $3.961 billion in fiscal 2024. The figures and earlier growth goal were reported in Plexus’s fiscal 2025 results release.

Revenue growth is not the same as profit growth
Fiscal Q3 2026 profitability depends on which accounting measure is used. Plexus reported a 4.7% GAAP operating margin and diluted EPS of $1.58. Its non-GAAP operating margin was 6.3%, and non-GAAP diluted EPS was $2.32; those non-GAAP figures excluded $0.74 per diluted share of stock-based compensation expense. The measures should not be mixed: GAAP results include expenses that the adjusted figures exclude.
For comparison, fiscal 2025 GAAP operating margin was 5.0%, with GAAP diluted EPS of $6.26. A higher revenue run rate is encouraging, but durability also depends on whether new production carries healthy margins and whether costs rise alongside sales.

What could keep the growth going?
Plexus attributes its faster growth to new program ramps and share gains, growing faster than modest end-market growth. It has highlighted opportunities connected with defense, data-center power and semiconductor equipment, alongside its broader served markets. Those are company growth claims and opportunity areas, not proof that future sales are secured.
- Program conversion: New wins need to move into production on schedule. Delays can push expected revenue into later periods; poor execution or pricing can make a ramp less profitable than its sales suggest.
- End-market demand: Strong orders in industrial and semiconductor-related markets can support growth, but those markets are cyclical. A slowdown could weaken demand even if Plexus executes well.
- Share gains: Taking a greater portion of a customer’s manufacturing work can add sales, but the benefit lasts only if customers continue ordering and the work remains economically attractive.
What could interrupt the growth story?
Ramps may be delayed or less profitable
Forecast revenue depends on programs reaching production. Timing changes, manufacturing challenges or unfavorable costs can reduce or defer the contribution from a program win.

Customers and markets can be concentrated
Exposure to cyclical industrial and semiconductor-equipment demand makes results vulnerable to changes in customer orders. Customer concentration can amplify that exposure if a significant customer reduces or delays work. These are risks to monitor, not evidence that a downturn has already occurred.
Growth must convert into cash
More production can require additional inventory and equipment before customer payments arrive. Revenue growth alone does not show how much cash remains after that investment. Investors should watch cash generation alongside sales and margins to judge whether expansion is self-funding.

Healthcare growth may be slower
The growth thesis also flags potentially slower healthcare growth. If some markets expand less quickly than others, total results may rely more heavily on the faster—but potentially more cyclical—areas.

No. A stronger operating outlook does not by itself establish that PLXS is a good investment at its current price. Valuation matters because the share price reflects expectations about future growth; if those expectations are already high, even solid results may not be enough to deliver attractive returns. Price, valuation and analyst-rating snapshots are time-sensitive and should be checked against current market data rather than treated as durable facts. Business growth and investment suitability are separate judgments, and neither guarantees future stock performance.
