Its top 10 customers accounted for 56% of fourth-quarter revenue, reflecting deep relationships with a concentrated base of large original equipment manufacturers.

Plexus Corp. (PLXS) Stock Price Performance: Last 30 Days vs. Quarter
Over the last 30 days, PLXS shares declined approximately 18%, moving from a closing price near $266 to a recent level around $218. The move was uneven: the stock climbed into early October before a sharp sell-off in the second half of the month, including a notable single-day decline in late October.
Over the last quarter, the stock is down roughly 9%. The three-month trend has been volatile rather than linear. After trading near $240–$250 at the end of July, the shares rallied through September and into early October, then gave back those gains as selling accelerated. The result is a net quarterly decline that is smaller than the 30-day drop, underscoring how much of the weakness was concentrated in recent weeks.
What Drove PLXS Stock Price in the Last 30 Days
The decline stands out because it coincided with strong fundamentals. On October 28, Plexus reported fiscal fourth-quarter revenue of $1.43 billion, up 35% year over year and ahead of guidance, with non-GAAP diluted EPS of $2.84 versus a consensus near $2.55. The company also issued fiscal first-quarter 2027 guidance above analyst expectations. Despite the beat, the shares did not rally and subsequently moved lower, a pattern consistent with a "sell the news" response.
The most likely explanation is profit-taking after a substantial run-up. Having risen more than 70% over the trailing 12 months, the stock entered October at elevated levels, leaving it vulnerable to a valuation reset even in the absence of negative company-specific news. The late-October selling appears tied to that positioning rather than any deterioration in demand or execution, given that fiscal 2026 results, the record $4.9 billion qualified manufacturing funnel, and raised margin targets all pointed in a positive direction.
What Drove PLXS Stock Performance Over the Last Quarter
The broader three-month narrative is one of strong operating momentum punctuated by a sharp pullback. During the quarter, Plexus delivered record fiscal 2026 results, including 23% revenue growth, a 62-day cash cycle, and a return on invested capital of 15.8% — above its 15% goal. Aerospace/Defense revenue grew 23% for the year, Industrial grew 27% (led by semiconductor capital equipment), and Healthcare/Life Sciences grew 19%.
Management's decision to raise its non-GAAP operating margin target to 6.5%–7.0%, up from 6.0%, and to guide fiscal 2027 revenue growth in the mid-to-upper teens reinforced the long-term growth story. Against that backdrop, the stock's late-quarter decline appears driven more by positioning and valuation than by a change in the company's trajectory, leaving the shares down roughly 9% over three months despite improving fundamentals. From what I see, this setup warrants close monitoring in the coming weeks.
PLXS Stock Forecast Drivers: What Investors Should Watch Next
Looking ahead, investors are likely to focus on execution against management's fiscal 2027 guidance of mid-to-upper-teens revenue growth and the new 6.5%–7.0% operating margin target. First-quarter commentary points to sequential strength in Aerospace/Defense and Healthcare/Life Sciences, partly offset by demand normalization in the Industrial sector, where semiconductor capital equipment momentum remains a key variable.
Additional factors to monitor include conversion of the record $4.9 billion qualified manufacturing funnel into revenue, the pace of new program ramps, and continued progress on the 62-day cash cycle. Broader risks include semiconductor cycle fluctuations, interest-rate sensitivity across capital equipment end markets, and supply chain or regulatory developments in defense and healthcare. Share repurchases under the newly approved $100 million program may also influence trading dynamics.
