The scores
The profile · 1-4
Growth3/4 ↑
Fast and organic, but narrowing - the top ten customers went from 64% of sales to 79%, and one end market drives all of it.
Business quality2/4 ↑
Programs get re-bid and dual-sourced by its own account, and every design rival it names is larger. Its wider margin is a symptom.
Financial position3/4 →
Net cash and low leverage, but the plan was not funded from operations: it needed $3.45B of equity nine days after the filing said otherwise.
Execution record3/4 →
Eight straight quarters above guidance, but the July filing said operations would fund the plant spending and an equity raise followed nine days later.
Per share capture2/4 ↓
The count was flat for a year, then rose 9.7% in one week at a 16.5% discount, unrestated in the earnings guidance.
Potential2/4 ↑
It is somebody else's spending plan and nothing is contracted: the annual report never says backlog, and no agreement states a volume or term.
Risk profile2/4 ↓
Three customers are 63% of quarterly sales and Thailand makes 59% of what it sells; either concentration on its own would be the level above.
Valuation2/4 →
The price needs the plan and the acceleration beyond it. Remove the share-price swap and the trailing profit looks dearer still.
Evidence quality3/4 →
Every load-bearing figure is filed, but what the price is measured against is management's own guidance and a vendor's analyst panel, neither verified.
The Verdict
We rate Celestica unattractive. It builds network switches and AI server racks for the cloud giants, and increasingly helps design them. The business is mixed: sales are growing fast, but extra sales barely add cash, shareholders have just put in new money, and part of the profit is a gain tied to its own share price. The price is full, not cheap: buyers count this year's plan and next year's faster growth as done; any slip hurts. The view hinges on free cash rising with sales without more shares being sold. The growth is real; the profit the price rests on is flattered, and the growth costs ever more capital.
The long caseCloud giants are filling new AI data centres with switches and server racks Celestica builds; their spending must keep rising and its extra sales must start bringing in cash.

The company
A cloud company that wants a switch built to its own design cannot buy one off the shelf, and does not want a factory. Celestica buys the chips, boards and power supplies, then assembles, tests and ships the finished system.
More and more it helps write the design too. That design-led work was 41% of sales in 2025, up from 21% in 2023. An older business, 18.9% of sales, builds electronics for aerospace, defence and industry.

Celestica is paid for each system it builds. On a plain assembly job it earns a fee for the work; on a design it helped write, the price also carries its own design content. Margins are thin either way: the cloud business kept 8.7 cents of each sales dollar as profit in the June quarter, the highest in its history.

Who runs it
Robert Mionis has run Celestica since 2015 and turned a low-margin assembler into a designer of cloud hardware. The finance chief of nine years moved to a sales role on 1 October; Todd Ankenmann, a finance executive there since 2018, replaced him. Insiders own about 1% of the company. The bonus pays on sales, profit margin and cash; most shares pay on earnings per share over three years, none on return on the money spent on new plants.

Robert Mionis has been chief executive since August 2015; Mandeep Chawla, chief financial officer since 2017, became Group President, Global Markets on 1 October 2026, and Todd Ankenmann, at Celestica since 2018 after a decade at General Electric, became chief financial officer.

As of 27 March 2026 the 17 directors and executive officers owned 1,260,777 shares, 1.10%; Robert Mionis held 1,010,091, under 1%; FMR at 6.4% and BlackRock at 5.5% were the only holders above 5%, and the proxy lists one class, common shares.

Celestica's annual team bonus pays on GAAP revenue (40%), non-GAAP operating margin (40%) and non-GAAP free cash flow (20%), and paid 185% for 2025; equity is 40% restricted units and 60% PSUs that vest on three-year non-GAAP adjusted EPS, modified up to 30% either way by relative shareholder return, and the 2023 PSUs vested at 200%.
against this
- Nothing pays on return on capital while plant spending runs to about 6% of revenue (C09), and free cash flow carries a fifth of the bonus only.
- The revenue component cannot pay above target unless target non-GAAP operating margin is met, so growth bought at a lower margin is not rewarded on its own.

Why it wins, and who could beat it
Why customers come back
Because Celestica co-designs the switch and has already ordered the parts, often more than a year ahead, a customer that moves a programme restarts two clocks: approving a new supplier's design, and rejoining a year-long queue for components. Management says customers now ask it to take back work they had given to second suppliers.
The limit is that this protects a programme already running, not the next one, which is bid again.

C25management claimlow confidence
Celestica has about 2,000 design engineers by the end of 2026 and says customers ask it to take back share previously given to a second source, because it can produce reliably at scale.
against this
- Nothing outside the company measures this. Neither share nor design wins are disclosed by Celestica or by any of its five filed competitors, so the claim cannot be checked against a number.
- The same answer concedes that products are commonly dual-sourced at award and offloaded as they mature, which is share moving in both directions rather than a one-way gain.
The threat
The rivals it loses work to are Taiwanese builders such as Hon Hai and Quanta, often already approved as second supplier on the same programme. Jabil has built a whole division around the same buyers. And NVIDIA sells its own network inside the rack, so a buyer of NVIDIA systems needs no separate switch.

against this
- The denominator is not an addressable market. Much of the four buyers' spending is land, buildings, power and the accelerator silicon, none of which Celestica sells, so the true ratio against what it can bid for is materially higher than 5%.

What growth costs
Growth has made Celestica more profitable: overhead and share pay barely rose while sales soared, so margins widened. Part of that comes from the share-price bet booked as lower overhead. The real cost of growth is now new factories, which take cash rather than margin, and that bill is rising faster than sales.

The September quarter beat the top of the company's own forecast: sales of $5.83B, up 83%, and adjusted profit per share of $3.30. It raised the 2026 forecast to $21.0B of sales and gave a first 2027 forecast of $40.0B, up 90%, with a profit margin of 9.0%.
The cash side moved the other way: free cash for 2026 was cut from $600M to $460M and 2027 plant spending set at $1.5B to $2.0B. On the call, managers called 2027 a year of investment and expected free cash to turn positive in 2028.

On the Q3 2026 call, held before the Investor and Analyst Day, management said 2027 'is going to be a year of investment' with no 2027 free cash flow figure; that the $3.5 billion of equity raised in August should be sufficient, with about $4 billion of cash and further liquidity; that it is confident of returning to positive free cash flow in 2028; that 2027 plant spending of $1.5B to $2.0B is for programmes already won and covers 2027 and 2028; that gross margin stays in the low 11s with operating margin expanding to 9% in 2027; that it has renewed its share buyback for up to 2.5% of shares, to be used opportunistically behind organic growth; and that customers are well funded.
against this
Management gave no figure for 2027 free cash flow or working capital, and 2026 free cash flow was cut to $460M (C53); the 2028 target is a statement of confidence, not a number.
What management did with the money
On 27 July its filing said operations would pay for this year's plant spending. Nine days later it sold $3.45B of new shares, 16.5% below the market price, adding 9.7% to the share count. The earnings forecast of $11.30 a share was never restated for them.

The price, and where we disagree
In short. Full. The growth is real, but the price pays for next year's faster growth too, on a profit flattered by share-price gains and growth partly paid for by shareholders; it is cheaper than in September.

The price fell 13.3% in the session after the offering was announced, the only strong measured move in the news batch.
How we read the multiple
Counting debt and new cash, the whole company cost about 32 times last year's operating profit in September, against about 25 for its rivals; those rivals were not re-checked after the fall.
Remove gains from a swap tied to its own share price and the filed profit makes it about 21.6 times at the 26 October close, down from 36.6. On this year's raised forecast, about 15.9. The price still asks for this year's plan and next year's faster growth, none of it contracted, but the premium is smaller.
Against its own history. Many times dearer for each dollar of sales than its own six-year normal. The business changed, but the price moved much further.
The evidence under this - 4 claims
C21estimatemedium confidence
At the 26 October close of $246.65 on 126,111,808 shares, enterprise value is about $28.0B, which is about 15.9 times the adjusted operating profit the raised 2026 guidance implies (8.4% of $21.0B) and about 21.6 times the trailing operating profit filed, with swap results removed.
derived126,111,808 shares at $246.65 is $31.11B; less cash of $3,961.3M at 30 September, plus $818.8M of borrowings and finance leases, gives $27.96B. Divided by 8.4% of $21.0B, which is $1,764M, and by about $1,293M of trailing operating profit (the trailing figure of the 11 September pack, $1,109M, less Q3 2025 earnings from operations of $325.0M without its $48.5M swap gain, plus Q3 2026 earnings from operations of $460.0M with its $0.9M swap loss added back).
against this
- The trailing figure is our roll-forward of the pack's, and the swap result in selling and administrative expense is not separated, so the multiple is approximate.
- The five competitors its own annual report names traded at a median near 25 times on trailing figures in September; that group was not re-struck after the fall, so the gap to it is not known today.

Where we disagree with the market
The market believes
An AI infrastructure winner whose faster growth and rising margins in 2027 justify paying far more than for a contract manufacturer.
We believe
The growth is real. The profit it is priced on is flattered by a share-price swap, and the growth now costs far more capital.
Most analysts rate the shares a buy, and their 2027 sales figure sits 75% above this year's forecast. What troubles us sits where headlines do not reach: the swap in a note to the accounts, and the cash the growth swallows.
We would be wrong if free cash turns positive on 2027 sales with plant spending at or below $2.0B, the opposite of what management said on the 27 October call.

What could go wrong, and how we would know
The risks
- Three customers, 63% of sales. The top ten went from 64% of sales to 79% in two years, and the two new programmes deepen that rather than spread it.
- Nothing is contracted. The OpenAI and AMD programmes are described as multibillion-dollar 2027 opportunities, with no volume, term or signed agreement behind them.
- Growth that eats capital. Plant spending is about 6% of sales this year, against 1.5% to 2% historically, and was paid for with new shares.
- One country makes most of it. Thailand made 59% of 2025 sales, up from 46% in 2023.
