1. Executive Summary
Sanmina spent most of its history as one of the less glamorous names in electronics manufacturing, a company that assembled circuit boards and systems for other people's brands and traded at a multiple that reflected exactly that. Over the past year, the story changed. Communications, cloud, and AI infrastructure now account for roughly 62% of revenue, up sharply from where the business sat even eighteen months ago, and the fiscal third quarter results reported July 27, 2026 show that shift translating directly into growth. Revenue came in at $3.46 billion, up 69.7% year over year and ahead of consensus. Non-GAAP EPS hit $3.31, more than double the prior year figure and roughly 19% above what analysts had modeled. Non-GAAP operating margin expanded 230 basis points to 8.0%. Management raised full year revenue and EPS guidance on the back of it.
The stock fell roughly 17% to 20% in the days that followed.
That disconnect is the actual subject of this note. Sanmina's fourth quarter revenue guide of $3.3 billion to $3.6 billion landed below where the sell side had modeled, and free cash flow for the quarter, at roughly $24 million against $117 million of net income, was thin relative to the size of the earnings beat, driven by a large inventory build and elevated capital spending. In a stock that had already more than doubled over the preceding twelve months on the strength of the AI infrastructure narrative, a quarter that was very good rather than flawless was enough to trigger a sharp repricing, and several sell side desks trimmed price targets even while maintaining constructive underlying ratings on the name.
None of this erases the operating strength that is visible in the results. Core Sanmina revenue, the legacy manufacturing business excluding recent acquisitions, grew 17% year over year on its own, evidence that the underlying franchise is healthy independent of any single deal or narrative. The balance sheet remains conservative, with $1.84 billion in cash and no borrowings drawn against a $1.5 billion revolver, and the board has continued returning capital through a fresh buyback authorization. This note treats the genuine operating momentum and the structural questions around cash conversion, customer concentration, and valuation as equally real, and asks readers to hold both at once rather than defaulting to either the bull or the bear framing alone.
2. Business Overview
Sanmina is a global provider of integrated manufacturing solutions, operating across two primary reporting segments.
Integrated Manufacturing Solutions (IMS) covers printed circuit board assembly and test, final system assembly and test, and direct order fulfillment. IMS revenue reached $2.96 billion in fiscal Q3 2026, up 79.4% year over year, and is the segment carrying the bulk of the company's current growth.
Components, Products and Services (referred to in recent disclosures as GPS) includes interconnect systems and mechanical systems. This segment posted $546 million in fiscal Q3 2026 revenue, up 29.2% year over year.
End markets span industrial and energy, medical, defense and aerospace, automotive and transportation, and communications networks, cloud, and AI infrastructure, the last of which has become the dominant growth driver and now represents the majority of total revenue. Sanmina operates in 20 countries across four continents, with a significant share of manufacturing capacity in lower cost regions across Latin America, Asia, and Eastern Europe.
A meaningful part of the current growth traces to the October 2025 acquisition of ZT Systems' data center infrastructure manufacturing business, purchased for up to $3 billion, which added scale, liquid cooling capability, and hyperscale cloud and AI infrastructure manufacturing experience to Sanmina's existing footprint. The deal is being integrated on a stated three phase plan, and contributed approximately $1.1 billion of revenue in fiscal Q3 2026 alone. Management's stated target, reiterated on the Q3 call, is $16 billion or more in annual revenue by fiscal 2027, with higher growth expected in the back half of that year and into fiscal 2028 as AI data center buildout continues.
3. Deep Dive: A Quarter That Beat on Every Line and Still Got Sold
Sanmina's fiscal third quarter, ended June 27, 2026, beat on essentially every headline metric that typically moves a stock higher. Revenue of $3.46 billion beat consensus of roughly $3.40 billion. Non-GAAP EPS of $3.31 beat consensus of approximately $2.77 to $2.83 by nearly 20%. Non-GAAP operating margin expanded to 8.0% from 5.7% a year earlier. Management raised full year revenue guidance to $14.0 billion to $14.3 billion from a prior $13.7 billion to $14.3 billion range, and raised full year non-GAAP EPS guidance to $11.90 to $12.20 from $10.75 to $11.35, both increases landing above where the Street had modeled.
The stock fell 4.9% on the day of the print itself as investors focused on fourth quarter guidance rather than the quarter just reported. Sanmina guided Q4 revenue to $3.3 billion to $3.6 billion and non-GAAP operating margin to 7.5% to 8.0%, both of which read as a deceleration relative to the momentum of the prior two quarters even though neither was, in isolation, a weak number. Over the following days the decline extended, with the stock down as much as 17% to 20% from its pre-earnings level before partially recovering to $193.23 by August 3.
Several sell side desks cut price targets in the days following the print, including reported reductions at JPMorgan and BofA, while generally maintaining constructive underlying ratings on the stock. That combination, lower targets alongside unchanged or improved fundamental views, is typically a signal that the cut is about near term multiple compression rather than a change in the long term thesis. It is also a fairly clean illustration of how little room a stock has once it has already re-rated sharply. Sanmina had more than doubled over the preceding twelve months heading into this print, and a quarter that most companies would present as an unambiguous win instead became the occasion for the market to ask whether the growth rate itself was about to decelerate, a question guidance did nothing to fully settle.
4. Deep Dive: The Cash Flow Gap Underneath the Earnings Beat
The headline EPS beat obscures a cash flow picture that tells a more complicated story. Free cash flow for the quarter was approximately $23.7 million to $24 million, a small fraction of the $117 million in net income reported for the same period, itself nearly double the $69 million reported a year earlier. That gap is explained primarily by a large inventory build, which grew 87.2% year over year to $2.2 billion, and elevated capital expenditure of roughly $101 million, both tied to capacity investment supporting integration of recently acquired manufacturing capacity.
This is not, on its own, a red flag. Scaling a capital intensive manufacturing business ahead of revenue recognition routinely requires working capital and capex investment that runs ahead of reported earnings, and management has framed the inventory build as deliberate positioning for anticipated demand rather than a sign of slowing sell-through. But it does mean the quarter's reported earnings growth outran its cash generation by a wide margin, and it is a reasonable candidate for part of what the market was pricing when it discounted an otherwise strong print. Investors relying on the EPS growth rate alone are seeing a more flattering picture of the business than the cash generation currently supports, and the gap between the two is worth tracking each quarter for signs of convergence as the newly acquired capacity matures and inventory normalizes relative to revenue.

Segment detail, Q3 FY26: IMS revenue $2.96 billion, up 79.4% year over year. GPS revenue $546 million, up 29.2% year over year. Non-GAAP gross profit $370 million, or 10.7% of revenue. Non-GAAP operating expenses $94.7 million, or 2.7% of revenue. Non-GAAP EBITDA approximately $322 million.
Balance sheet, quarter end June 27, 2026: Cash and cash equivalents $1.84 billion. Short-term debt $215 million. Long-term debt approximately $1.96 billion. No outstanding borrowings on the $1.5 billion revolving credit facility. Current ratio 1.71. Debt to equity 0.93. Inventory $2.2 billion, up 87.2% year over year.
Full year fiscal 2026 guidance, as raised on the Q3 call: Revenue $14.0 billion to $14.3 billion. Non-GAAP EPS $11.90 to $12.20. Non-GAAP operating margin 6.85% to 7.25%.
Fiscal Q4 2026 guidance: Revenue $3.3 billion to $3.6 billion. Non-GAAP operating margin 7.5% to 8.0%. Non-GAAP EPS $3.05 to $3.35.
Capital return: The board approved a new $600 million share repurchase authorization in connection with the Q2 FY26 report, after the prior authorization was fully utilized, a signal of management's willingness to return capital at current valuations even while mid acquisition integration.
Customer concentration: Sales to the company's ten largest customers accounted for 52% of net sales in fiscal 2025, with the single largest customer representing 10.1% of net sales in both fiscal 2025 and fiscal 2024. This concentration is a longstanding structural feature of the contract manufacturing model, not a new development, but it remains a relevant input to how much confidence investors should place in any single quarter's growth rate.
Reading the numbers: The widening gap between net income growth (up roughly 70% year over year in Q3) and free cash flow (down to roughly $24 million from a much larger base of net income) is the single most important reconciliation item in this report. It most plausibly reflects real, necessary investment in capacity ahead of demand rather than a deterioration in the underlying business, but it means investors relying on the EPS growth rate alone are seeing a more flattering picture than the cash generation currently supports.
6. Competitive Positioning
Sanmina competes most directly with Celestica, Flex, and Jabil in the electronics manufacturing services and vertically integrated systems space, and all four names have re-rated meaningfully on AI infrastructure exposure over the past eighteen months, though not to the same degree or on the same underlying fundamentals.
Celestica has been the standout performer among direct peers, with its Connectivity and Cloud Solutions segment driving a stock re-rating that has pushed trailing and forward multiples well above Sanmina's, alongside return on equity near 52% and return on invested capital near 39%, both dramatically higher than Sanmina's current 10.96% and 12.20%. Celestica's re-rating reflects a business that has converted AI infrastructure exposure into returns on capital that Sanmina has not yet matched.
Flex presents a similar pattern to Celestica at a somewhat more moderate scale, with returns on equity and invested capital of roughly 17% and 16%, ahead of Sanmina, alongside a PEG ratio near 0.66, close to Sanmina's own 0.64.
Jabil remains a large diversified peer with meaningful data center and cloud exposure, though it has historically carried thinner margins than Celestica given a broader, less AI-concentrated revenue mix.
The pattern across the group is consistent. The market has rewarded AI infrastructure exposure broadly, but it has rewarded demonstrated returns on capital more than exposure alone, and on that specific measure Sanmina currently trails both Celestica and Flex by a wide margin. Sanmina's bull case depends in significant part on closing that gap as recently acquired capacity matures and its margin profile improves from its current, still developing level.
7. Valuation
At $193.23 and approximately 53.6 million shares outstanding, Sanmina carries a market capitalization of roughly $10.4 billion.
Multiple | Sanmina | Celestica | Flex |
Forward P/E | ~17-18x | ~37.6x | ~30.1x |
Trailing P/E | ~43.2x | ~51.7x | ~58.7x |
PEG ratio | 0.64 | n/a | 0.66 |
EV/EBITDA | 22.2x | ~31-36x | 25.4x |
ROE | 10.96% | 52.45% | 17.35% |
ROIC | 12.20% | 39.37% | 16.21% |
Debt/equity | 0.93 | 0.45 | 0.87 |
The table above summarizes the central valuation tension in this stock. Sanmina trades at a meaningful discount to both Celestica and Flex on forward earnings multiples, which on the surface reads as the cheapest way to buy AI infrastructure exposure in this peer group. That discount is not obviously a mispricing. It tracks fairly closely with Sanmina's lower returns on equity and invested capital relative to both peers, particularly Celestica, whose re-rating has been backed by returns on capital several multiples higher than Sanmina currently generates. The market appears to be pricing Sanmina as the AI infrastructure story that has not yet proven it can convert scale into the same capital efficiency its peers have already demonstrated, rather than as a stock the market has simply overlooked.
What appears priced in at the current level: continued double digit core business growth, successful integration of recently acquired manufacturing capacity roughly on the timeline management has described, and margin expansion that closes at least part of the gap to peer returns on capital over the next one to two years. What appears less fully priced in, based on the magnitude of the post earnings reaction to guidance that was merely good rather than exceptional: the risk that free cash flow conversion remains weak relative to reported earnings for longer than the market currently assumes.
8. Bull and Bear Scenarios
Bull case.
Sanmina has converted itself from a low margin, low multiple contract manufacturer into a company where communications, cloud, and AI infrastructure drive the majority of revenue, and the fiscal Q3 2026 results show that conversion is real rather than aspirational, with core business growth of 17% and 230 basis points of operating margin expansion in a single year. A conservative balance sheet, $1.84 billion in cash, no revolver borrowings, and a fresh $600 million buyback authorization, gives management room to keep investing in newly acquired capacity without external financing pressure. Under this case, Sanmina's current discount to Celestica and Flex on forward earnings multiples closes as returns on capital improve with scale, and the stock's post earnings selloff proves to have been a buyable overreaction to guidance that was conservative rather than genuinely weak.
Bear case.
Sanmina's free cash flow has not kept pace with its reported earnings growth, and a $2.2 billion inventory build alongside elevated capex suggests recently acquired capacity is consuming more working capital than the headline EPS numbers reveal. Customer concentration remains a structural feature of the business, with the top ten customers representing 52% of net sales, regardless of how the AI narrative evolves. And a stock that had already more than doubled over twelve months demonstrated, through its reaction to a genuine beat and raise quarter, that it has very little tolerance for guidance that is merely good, which caps the near term upside case even if the underlying business continues to execute roughly as planned.
Both scenarios describe the same company at the same point in its transformation. The disagreement is over how much patience the market will extend for returns on capital to catch up to the multiple Sanmina already commands relative to where it started this cycle, even after a 43x trailing P/E has come down from its recent extremes.
9. Risks and Sensitivities
Prioritized, not exhaustive:
Customer concentration. Top ten customers represented 52% of net sales in fiscal 2025, with the single largest customer at 10.1%, a longstanding structural feature of the contract manufacturing model that leaves results exposed to any single large customer's order changes.
Free cash flow conversion. Free cash flow of roughly $24 million against $117 million of net income in the most recent quarter, driven by inventory build and elevated capex, is worth tracking closely for signs of normalization.
Valuation sensitivity to guidance quality. A stock that fell 17% to 20% on a beat and raise quarter has demonstrated it is pricing in a high bar, leaving limited room for anything less than continued upside surprises.
Integration execution. Recently acquired manufacturing capacity is being integrated on a stated multi phase plan, and large scale manufacturing integrations carry the ordinary risk that synergies take longer to materialize than guided.
End market cyclicality. Communications, cloud, and AI infrastructure now represent the majority of revenue, concentrating Sanmina's fortunes in a capex cycle that has historically proven capable of sharp digestion periods following periods of rapid buildout.
Beta and volatility. A beta of 1.56 and a 52-week range spanning $108.37 to $288.68 indicate a stock prone to sharp repricing on both fundamental and sentiment-driven news.
10. Conviction and Portfolio Framework
The following is offered as an interpretive framework for readers doing their own position sizing work, not a recommendation.
Sanmina occupies a middle position within the AI infrastructure manufacturing group. It is neither the highest returning name in the group, that distinction currently belongs to Celestica on both ROE and ROIC, nor is it an unproven story, given that core business growth and margin expansion are already showing up clearly in the reported numbers. It trades at the cheapest forward multiple among its closest direct peers, a discount that appears explained by its comparatively lower returns on capital rather than by simple market oversight.
The central sizing question is whether that gap in returns on capital closes as recently acquired capacity matures, or whether the current lower returns reflect a structurally less profitable business mix that persists even after integration costs fade. Readers with high conviction that Sanmina's margin trajectory improves over the next several quarters have a stronger case for a larger position than readers primarily attracted to the AI infrastructure headline growth rate without a formed view on why Sanmina's returns on capital currently trail Celestica's and Flex's by a wide margin.
Key monitoring points going forward:
Fiscal Q4 2026 earnings, expected November 2026: watch specifically for free cash flow conversion relative to net income, and whether the inventory build normalizes as guided.
Return on invested capital trend over the next several quarters, as the clearest signal of whether Sanmina's returns are converging toward peer levels or remaining structurally lower.
Sell side price target revisions in the weeks following each print, as a read on whether the market's tolerance for guidance that is merely good rather than exceptional has changed.
