AI demand lifts Delta, but bond overhang and rotation cap gains

AI data-center demand and product ramp Analysts raised 2027 AI spending forecasts, and Delta is ramping its 800-volt power system for NVIDIA's Vera Rubin, positioning it to capture more of the AI infrastructure buildout.
This is the main growth driver behind Delta's business and stock appeal.
Easing shortages and peak Q3 profit Component shortages are easing, and Q3 profit is expected to peak, which supports earnings momentum and gives investors confidence in near-term results.
It explains the improved operational backdrop and profit outlook.
Broker upgrades and improved sentiment Krungsri upgraded the sector and named Delta a top pick, while Bualuang kept a 330 baht target. US-China AI talks and an extended trade truce also lifted sentiment.
These events boosted investor confidence and buying interest.
Exchangeable bond overhang and sector rotation A $1.5 billion exchangeable bond creates a share overhang, capping the stock, which fell 6% on the news. Investors also rotated into KCE and HANA, limiting Delta's rebound.
This is the main counterweight that held back the stock despite positive drivers.

Delta's AI power and cooling orders strengthen as trade tensions ease

US-China AI talks and extended trade truce lift sentiment Trump and Xi held their first talks on AI and extended the trade truce to January 2027. Less chip and trade tension is good for Delta, because its AI data-center power and cooling gear sells into a global build-out that depends on open trade.
New geopolitical de-escalation directly improves the outlook for Delta's AI-linked demand.
AI racks need far more power, raising Delta's content per rack Morgan Stanley raised its power estimate for NVIDIA's next racks, and Bualuang kept a 330 baht target, seeing Q3 sales up 34% year on year. More power and cooling per rack means Delta sells more valuable equipment in each AI data center.
This is the core demand driver behind Delta's earnings growth and stock price.
Delta launches 800 VDC AI data-center system for NVIDIA Vera Rubin Delta unveiled a modular AI data center with 800-volt in-row power and liquid cooling built for NVIDIA's Vera Rubin. Winning a place in the next-generation AI architecture supports future orders and shows Delta's technology is central to the build-out.
A concrete new product tied to NVIDIA's roadmap strengthens Delta's competitive position.
Brokers turn more bullish, naming Delta a top pick Krungsri upgraded electronics to Bullish and picked Delta with a 320 baht target, expecting 51% profit growth in FY27. Kasikorn also named Delta a stock to accumulate on market dips, citing strong AI demand and recovering margins.
Upgraded recommendations and higher targets can pull investor money back into the stock.

Delta's AI power demand stays strong, but bond overhang and rotation cap the stock

AI data-center demand keeps building Delta is ramping raw materials for its new 800-volt AI data-center power system, and analysts say big tech's 2027 AI spending plans are being revised sharply higher. More AI factories mean more orders for Delta's power gear, supporting revenue and prices.
This is the core growth engine behind Delta's earnings and the main reason analysts stay positive.
Supply shortages ease, profit seen peaking in Q3 The component shortages that squeezed Delta earlier in 2026 are easing, and analysts expect third-quarter sales and profit to be the year's best, helped by orders pushed from the second quarter and better margins. That points to a profit recovery.
It explains why earnings are expected to improve after a weak first half, a key support for the share price.
$1.5 billion exchangeable bond creates a share overhang Delta's Singapore unit is issuing $1.5 billion of bonds that can later be swapped into Delta shares at 267-302 baht. No new shares are issued now, but hedging and future selling pressure can cap the stock, which fell about 6% on the news.
This is the clearest new negative force weighing on the share price this period.
Money rotates out of Delta into other electronics names Some investors moved money out of Delta into KCE and HANA, which are seen as having stronger near-term profit prospects, and Delta also tracked its weaker Taiwan parent. This competition for investor money limits how fast Delta can rebound.
It shows a real counterweight: even with good AI news, investor money is choosing other stocks.
