CLS vs TTMI
Which Stock Would AI Choose? Celestica (CLS) vs. TTM Technologies (TTMI) Stock Comparison
Key Takeaways
- CLS and TTMI are both leveraged to the artificial intelligence (AI) infrastructure buildout, but through different roles: Celestica as an electronics manufacturing services (EMS) provider and TTM Technologies as a printed circuit board (PCB) and radio frequency (RF) component maker.
- Celestica has delivered sharper revenue acceleration and higher scale, while TTM Technologies has posted record quarterly results with a larger aerospace and defense (A&D) cushion.
- Both names have recently pulled back or whipsawed as AI-sentiment cooled, underscoring how tightly their valuations are tied to data center spending expectations.
- Celestica carries heavier customer concentration and rising capital spending; TTM Technologies carries elevated acquisition-driven debt and leverage.
- Relative positioning favors a nuanced view: Celestica offers stronger momentum in hyperscale compute, while TTM Technologies offers more diversified, defense-backed revenue.

Introduction
Celestica (CLS) and TTM Technologies (TTMI) are two technology-hardware suppliers whose fortunes have become closely linked to the artificial intelligence (AI) data center buildout, yet they operate at different points in the supply chain. Celestica designs and manufactures complex electronics and computing systems for hyperscale cloud customers, while TTM Technologies produces advanced printed circuit boards (PCBs) and radio frequency (RF) components serving both commercial and defense markets. This stock comparison is relevant for investors weighing high-growth AI infrastructure exposure against more diversified, defense-backed revenue, and for traders tracking how sentiment shifts around AI spending affect relative performance and market positioning.
CLS Overview and Recent Performance
Celestica is a Toronto-based electronics manufacturing services (EMS) company organized around two segments: Connectivity & Cloud Solutions (CCS) and Advanced Technology Solutions (ATS). Its CCS segment, driven by networking switches, servers, and storage for hyperscale cloud providers, has been the primary growth engine. In recent quarters, revenue growth has accelerated sharply, with second-quarter 2026 revenue rising roughly 62% year over year, and management raised its full-year 2026 outlook to approximately $20.5 billion in revenue and $11.30 in adjusted earnings per share (EPS). The company has also disclosed awards including a co-packaged optics (CPO) switch program and custom AI racks developed with Broadcom to support OpenAI's accelerator roadmap.
Despite strong fundamentals, CLS shares have pulled back meaningfully in recent weeks. The stock fell well below its year-to-date high amid a broader unwind of the "AI trade," as investors reassessed the sustainability of infrastructure spending. An August equity offering of roughly $3 billion also weighed on sentiment, while heavy capital expenditures tied to customer-awarded programs have drawn scrutiny. This combination of rapid growth, elevated valuation, and rising investment intensity has made Celestica a high-beta (more volatile) way to express an AI-infrastructure view.
TTMI Overview and Recent Performance
TTM Technologies is a global manufacturer of printed circuit boards (PCBs) and radio frequency (RF) and microwave components, serving aerospace and defense, data center and networking, medical, industrial, and automotive markets. In its most recent quarter, TTM reported record revenue of approximately $1.2 billion, up about 60% year over year, with non-GAAP earnings per share (EPS) more than doubling. Data Center and Networking represented about 41% of sales, growing roughly 115% year over year, while Aerospace and Defense contributed about 34% and reached a record program backlog of around $2 billion.
Recent market activity in TTMI has been volatile. Shares fell sharply after the company disclosed a "pushout" in one major data center program's production schedule, even as its overall results beat expectations; the stock then rebounded as investors absorbed the record quarter and raised guidance. TTM has also pursued an aggressive acquisition strategy, including the roughly $1.1 billion purchase of Epiq Solutions and a planned $650 million acquisition of Ophir Optics, which has lifted debt and leverage. Its diversified, defense-anchored backlog provides balance against the concentration risk of pure AI exposure.

Head-to-Head Comparison
The clearest contrast between the two companies is business model. Celestica assembles and integrates complete systems, giving it greater revenue scale and more direct exposure to hyperscale compute and networking demand, but also high customer concentration, with a large share of revenue tied to a handful of cloud giants. TTM Technologies supplies the underlying PCBs and RF components, positioning it one step earlier in the supply chain but with a broader customer base and a meaningful defense revenue stream that is less correlated with AI spending cycles.
On growth momentum, Celestica has shown the faster top-line acceleration, while TTM Technologies has posted its own record quarter and guided to a sharp revenue ramp for 2027. On risk, Celestica's heavier capital spending and concentrated customer base are key watch items, whereas TTM's acquisition-driven leverage and the recent data center program pushout represent its main overhangs. Market sentiment has been volatile for both, with each stock whipsawing on AI-related headlines, reinforcing that near-term price behavior in this pair is driven as much by narrative as by reported results.
Tickeron AI Verdict
Based on observable factors such as trend consistency, stability, catalysts, and relative positioning, Tickeron's AI would likely view TTMI as the more stable candidate in the current environment, given its record backlog, diversified revenue mix, and defense-supported demand. However, CLS would likely be favored for trend strength and earnings momentum, as its faster revenue growth and upward earnings-estimate revisions signal more powerful catalysts, albeit with greater volatility. The AI's probabilistic assessment would therefore lean toward Celestica for momentum-oriented positioning while recognizing TTM Technologies as the more defensive, balance-oriented alternative within this AI-infrastructure theme.

Long-Term Analysis
It is best to consider a long-term outlook for a ticker by using Fundamental Analysis (FA) ratings. The rating of 1 to 100, where 1 is best and 100 is worst, is divided into thirds. The first third (a green rating of 1-33) indicates that the ticker is undervalued; the second third (a grey number between 34 and 66) means that the ticker is valued fairly; and the last third (red number of 67 to 100) reflects that the ticker is overvalued. We use an FA Score to show how many ratings show the ticker to be undervalued (green) or overvalued (red).
CLS’s FA Score shows that 1 FA rating(s) are green while TTMI’s FA Score has 0 green FA rating(s).
- CLS’s FA Score: 1 green, 4 red.
- TTMI’s FA Score: 0 green, 5 red.
Short-Term Analysis
It is best to consider a short-term outlook for a ticker by using Technical Analysis (TA) indicators. We use Odds of Success as the percentage of outcomes which confirm successful trade signals in the past.
If the Odds of Success (the likelihood of the continuation of a trend) for each indicator are greater than 50%, then the generated signal is confirmed. A green percentage from 90% to 51% indicates that the ticker is in a bullish trend. A red percentage from 90% - 51% indicates that the ticker is in a bearish trend. All grey percentages are below 50% and are considered not to confirm the trend signal.
CLS’s TA Score shows that 4 TA indicator(s) are bullish while TTMI’s TA Score has 4 bullish TA indicator(s).
