A single-day surge of 11.6%—has Flex's AI power story come true?

Wednesday, October 28, 2026

A single financial report, recovering 11.6% in one day

Before the market opened on October 28, Flex delivered its second-quarter results: revenue of $8.49 billion, up 25% year-on-year, adjusted earnings per share of $1.18, a record high. The full-year guidance was raised again, with a surge in volume that day, surging 11.61% to close at $93.03, with trading volume about 3.2 times the three-month daily average.

But in the month leading up to today, this stock had pulled back more than 20% from its highs. Even after today's sharp rise, the price was still below the 50-day moving average of $107.11 and the 200-day moving average of $102.71.

On one side is record profits, on the other is an unrepaired trend line—is today's big bullish candlestick the starting point of a new market rally, or a breather after overselling?

Not just a contract manufacturer, but the "general contractor" of AI data centers

Many people still associate Flex as a "contract manufacturer assembling electronic products for others," but today it is more like an end-to-end delivery company that packages design, engineering, supply chain, and mass manufacturing to customers, serving eight major end markets: data centers, communications, enterprise, consumer, automotive, medical, industrial, and power.

The company operates in three major segments

Integrated Technology Solutions (ITS) covers high-speed networks, satellite communications, and consumer electronics, with Q2 revenue of $3.3 billion, up 22%; Regulated Manufacturing (RMS) covers medical devices, automotive computing, and power electronics, with Q2 revenue of $2.7 billion, up 9%.

What truly changed the valuation narrative was Cloud and Power Infrastructure (CPI): it offers integrated computing systems, advanced liquid cooling, and high-density power supply from utilities and facility layers to rack and board levels. Q2 revenue for this segment was $2.5 billion, a 54% year-over-year increase, with an adjusted operating margin of 10.7%, including about 16% from the power sub-business.

Its irreplaceability does not come from a proprietary patent, but from complex delivery capabilities: switching suppliers for data center, medical, and automotive customers means recertification, redesign, production line switching, and delivery risks, all of which constitute real conversion costs.

Think of it as the general contractor for AI data center renovation—the client isn't just a brick, but an entire building with electricity, cooling, and computing all in one place. But the general contractor often earns hard-earned money: Q2 gross margin about 9.6%, this company is still far from being a "high-margin tech stock." The moat is more accurately positioned as a mid-to-strong operational moat.

Whether it's 36x or 19x depends on which report you trust

Based on GAAP earnings per share of $2.59 over the past 12 months, Flex's price-to-earnings ratio (P/E) is about 35.92 times, which is not cheap for a manufacturing company with a gross margin below 10%; The P/B ratio of 6.25 times and the Enterprise Value Multiple (EV/EBITDA) of 21.53 times in the report snapshot are also not low.

But on another note, the picture is completely different: management raised its adjusted earnings per share guidance for this fiscal year to $4.84 to $5.16, with a midpoint of $5 representing a 52% increase, and the current price corresponds to about 18.6x forward P/E; The price-to-sales ratio (P/S) is about 1.21x, and the research report estimates a PEG as low as 0.37.

So why does the market only give a 19x forward P/E ratio? The answer lies in cash flow. Q2 free cash flow was $261 million, down from $305 million in the same period last year, of which $61 million was a one-time spin-off cost; Cumulative for the first half of the fiscal year was only $302 million, compared to $573 million in the same period last year.

In the last full fiscal year (ending March 2026), Flex had operating cash flow of $1.685 billion, free cash flow of $1.06 billion, and a return on equity (ROE) of 17.35%, indicating that self-sustaining ability is not an issue. However, to support growth, inventory has risen to $7.3 billion, a 39% year-over-year increase, with full-year capital expenditure planned at $1.5 to $1.6 billion, and management's full-year free cash flow conversion rate is only about 40%.

The report uses a scenario P/E ratio of 25 to 35 times to apply a midpoint earnings per share of $5, projecting a range clearly higher than the current price. But this conclusion only holds up if guidance is fulfilled and cash flow follows. Today's rally has already factored in the positive factors of "earnings beating expectations and upward guidance" in the stock price, while concerns about cash flow and debt have not been digested. Overall, the valuation is within a reasonable range, not significantly undervalued.

Operational breakthroughs have been made, but stock price remains uncertain

Looking at the operating data, Flex has shifted from "steady expansion" to "accelerated breakthrough": last fiscal year's revenue was $27.91 billion, up only 8.1%, while quarterly revenue climbed from $6.58 billion, $6.8 billion, $7.06 billion, $7.5 billion to $7.93 billion, and then $8.49 billion this quarter, with growth rising to 25%, and next quarter's guidance is about 28%.

But the stock price gave a different answer. The closing price of $93.03 was still about 9.4% below the 200-day moving average and about 13% below the 50-day moving average, with the 50-day moving average still above the 200-day line, indicating that the previous high-level shares had not yet been digested. The breakthrough in operations has been confirmed by data; the stock price breakthrough still needs confirmation in the next earnings report.

Caught between giant foundries and power supply experts

Flex's first group of competitors is giants like Celestica, Foxconn (Hon Hai), and Quanta Computer (Quanta), competing on scale, delivery speed, and unit cost. Celestia and Flex likely have the highest customer overlap in the AI server supply chain, while Foxconn and Quanta leverage their massive capacity and vertical integration to drive prices.

The second group of opponents is even more "specialized"

Delta Electronics directly covers power, thermal management, and data center infrastructure, directly facing CPI's liquid cooling, power conversion, and high-density power supply; Infineon Technologies, located upstream in power semiconductors, could be either a supplier or a substitute. Management expects component shortages to persist for several more years, which is constraining for all system integrators.

Flex's strength lies in its portfolio breadth: RMS has long regulated manufacturing certification cycles and is hard to shake by price wars, while CPI can integrate electricity, cooling, and computing for delivery; The drawbacks are that scale is not an absolute advantage, and gross margins are suppressed by major client bargaining.

If Foxconn is the "largest factory" and Delta is the "most electrically savvy engineer," then Flex wants to be the turnkey that can coordinate both simultaneously—The question is, how much more are customers willing to pay for "coordination capability"? Due to the lack of peer valuations and product-by-product data for the same period, we can only judge the business positioning and cannot yet determine whether Flex should enjoy a premium or a discount.

From 27.9 billion to 35.4 billion, it will take over two years to absorb another 7.5 billion

Authoritative market size data for data center computing, liquid cooling, and power supply is insufficient. The report adopts a bottom-up projection: last fiscal year's revenue was $27.91 billion, this fiscal year's midpoint guidance was $35.4 billion, with a two-year incremental increase of about $7.5 billion and cumulative growth of about 26.8%. The full-year CPI growth guidance is as high as 75% to 85% (about 10 percentage points from mergers and acquisitions).

The report's sensitivity framework assumes a broad market pool of $80 billion to $120 billion, with a serviceable market accounting for 35% to 50%, and a 3-year market share of 5% to 12%. Under the baseline scenario, revenue for the next two fiscal years is expected to increase by 8%-12% and 7%-10%, the optimistic scenario approaches $50 billion, while the cautious scenario stagnates near $35 billion. The ceiling is not the issue; the issue is whether the new revenue is of the low-margin type.

What bulls see is a steepening growth curve

The supporters' logic doesn't rely on imagination, but on a string of numbers that have already been realized:

In the next six months, four key points will determine the valuation direction

Today's earnings report is just the beginning; what will truly determine whether the stock price can climb back above the moving average is the following events in the coming months:

•	November 10 Innovation Day: Details of Axiom's business and product roadmap, with a strong impact but a focus on realization
•	Axiom spin-off completed in early 2027: asset revaluation or chip selling pressure, both directions
•	Third quarter financial report for around January 2027: Testing revenue guidance of $8.87 billion to $9.17 billion and cash flow recovery, with a strong impact
•	$2 billion Axiom convertible preferred stock transaction completed: used to repay approximately $2 billion in debt, benefiting the balance sheet
•	AI hardware demand signals from peers like Celestica, Foxconn, Quanta, and Delta: moderate impact from the second half of 2026 to 2027
•	If a formal document or ruling appears on USITC-related patent matters: first half of 2027, the direction is unclear

In the past year: a 30% gap and a 20% drawdown

FLEX has delivered a cumulative return of about 28.9% over the past 12 months, with the most critical turning point in May 2026: the company announced it would spin off its CPI for separate listing and raised its guidance. The stock price surged about 30% in early trading, and then in the first quarter of July, revenue was $7.93 billion and net profit was $285 million, further reinforcing the growth narrative.

But entering October, the market began to reassess growth quality: weakening cash flow, increased leverage through acquisitions, cooling sentiment in the AI hardware chain, and the stock price pulled back more than 20% in the month before the earnings report. Today's rebound shows that fundamentals are still recognized, but the market has shifted from "paying for the story" to "paying for deliveries".

⚠️ Risk Notice • If full-year revenue and adjusted earnings per share guidance are revised downward, high growth expectations will be quickly given back • Free cash flow remains weak than profits, with inventory and receivables occupying funds • Additional debt and interest burdens from acquisitions have temporarily suppressed GAAP profits • Uncertainty in the spin-off process, valuation, and customer concentration • Component shortages lasting for years may limit delivery pace and gross margins

🟡 Neutral Profits have been realized, but cash flow has not; today's gains have already accounted for most of the positive factors

💬 Discussion Bottom line: The performance is real, but don't chase the high price until cash flow recovers. Real-time buy and sell levels, post FLEX on the official WeChat account.
