Apple’s push into foldable phones, including a high-priced “iPhone Ultra,” is reshaping expectations for consumer electronics stocks. Higher potential revenue per device, a wider range of iPhone models, and Apple’s effort to cut memory chip costs by sourcing from Chinese suppliers like CXMT and YMTC could all ripple through the sector. For investors watching Apple and its broader supply chain, this news may change how future margins, pricing power, and demand are viewed. Below, the article looks at 3 stocks from the Technology Sector, Consumer Electronics screener that appear closely exposed to these developments.

ISU Petasys (KOSE:A007660)

Overview: ISU Petasys is a South Korean manufacturer of high end printed circuit boards used in equipment such as routers, servers, supercomputers, aerospace systems, and advanced driver assistance and RF radar modules, as well as IC tester boards that help chip makers test semiconductors.

Market Cap: ₩8.1t

ISU Petasys sits in the slipstream of premium smartphones like Apple’s planned foldable iPhone Ultra, supplying critical electronic components that benefit from higher device prices and rising complexity. Analysts expect strong earnings and revenue growth, with recent earnings growth and a net margin of 14.7% supporting a high but growth oriented P/E. The stock is flagged as trading below one intrinsic value estimate, which may appeal to investors who think current sentiment underestimates future PCB demand from data centers, high performance computing and flagship phones. Set against this are real concerns, including volatile trading, a balance sheet funded entirely by external borrowing and weak board independence, which could matter if conditions turn.

ISU Petasys looks like a growth story tied to premium devices, but the real question is whether the current P/E fairly reflects that potential or misses key risks hiding in the DCF valuation analysis for ISU Petasys

Delta Electronics (TWSE:2308)

Overview: Delta Electronics is a Taiwan based supplier of power and thermal management hardware and systems that sit inside everything from smartphones and EVs to factories, data centers and buildings, helping customers run electronics, automation and energy infrastructure more efficiently.

Operations: Delta Electronics generates the bulk of its revenue from its Power Supply and Spare Parts Business Group at about NT$305.9b, followed by the Infrastructure Business Group at around NT$198.7b, with smaller contributions from Automation, Transportation and other activities.

Market Cap: NT$5,389.9b

Delta Electronics may appeal to investors who are looking for consumer electronics exposure that also includes AI data centers and energy transition spending, in addition to demand related to Apple’s premium iPhone roadmap for high end components. The company reports strong earnings momentum, an ROE around 22.3% and net margins of 11.8%, which are presented as supporting a P/E above much of the TW Electronic sector even after a reported discount to one fair value estimate. However, factors such as heavy use of external borrowing, relatively low board independence and uneven performance in segments like Mobility mean the investment case involves risks and may warrant closer attention rather than assuming AI, data center and smartphone demand will be sufficient to offset these issues.

Delta Electronics’ earnings momentum and premium P/E suggest the market sees real strength here, but heavy borrowing and segment gaps raise questions. Get the full story in the analysis report for Delta Electronics

Sandisk (SNDK)

Overview: Sandisk develops and sells NAND flash based storage, including solid state drives and embedded memory that sit inside PCs, phones, tablets, wearables, cars, connected home devices and data center equipment. It reaches customers through device makers, cloud providers and retail channels worldwide.

Operations: Sandisk generates about US$13.2b from developing, manufacturing, marketing and selling data storage devices and solutions.

Market Cap: US$258.4b

Sandisk is tightly linked to the same forces lifting Apple’s premium iPhone roadmap, as higher storage content in flagship phones and AI capable PCs increases the amount of NAND per device. At the same time, AI data centers continue to draw in high capacity enterprise SSDs. The company reports high profitability metrics, with a 32.7% ROE and revenue and earnings forecasts well ahead of the broader US market. However, the stock trades on a rich 57.3x P/E and above one cash flow based value estimate, and uses 100% external borrowing. For investors, the key question is whether AI data center demand, BiCS10 advances and long term supply contracts justify paying this valuation premium despite governance concerns and a very strong recent share price run.

Sandisk’s rich 57.3x P/E and high 32.7% ROE suggest a story that goes beyond headline AI and iPhone demand, and the real tension sits inside the analyst forecasts for Sandisk
