Apple's Foldable iPhone Is Ternus's First Test as CEO
John Ternus inherits the most scrutinized product launch at Apple in years. The foldable iPhone and Siri AI overhaul are his chance to prove engineering-led leadership can redefine the category — not just follow it.
The First iPhone Keynote Without Tim Cook Carries More Weight Than usual
Apple has announced its next product event for September 9 at Apple Park in Cupertino. The headline is familiar — iPhone 18 Pro and Pro Max, new Apple Watches, an AI-powered Siri refresh. The context is not. This is John Ternus’s first major stage appearance as CEO.
Cook stepped down to executive chairman on September 1. He will still be in the building, still influencing strategy. But the question on every analyst desk is whether the new man at the top can carry a launch that matters.
Ternus has spent his Apple career inside the hardware organization. He was senior vice president of hardware engineering before the transition. That makes this moment structurally different from every iPhone launch under Cook, who rose through operations and marketing. Ternus is an engineer wearing the CEO suit. The product story he tells on September 9 will signal what kind of company Apple becomes next.
The Foldable iPhone Changes the Math
The most consequential detail in Apple’s upcoming announcement is not incremental. Analysts expect the iPhone 18 Pro to include a foldable variant — Apple’s first entry into a market Samsung has owned for years. The financial implication is significant.
Apple TV and Apple One prices have already risen again in the United States, a signal that the company is pushing average selling price upward through subscription and premium device mix. A foldable iPhone would accelerate that trajectory. Instead of another iterative Pro upgrade that moves the needle by single-digit percentages, Apple would be introducing a genuinely new hardware category with higher margins and higher ASP.
Bank of America framed it directly in an August note: Ternus could cement Apple’s device dominance in an AI-enabled era. The foldable form factor is the vehicle. AI is the engine. Together they shift the revenue composition.
Even Samsung Wants Apple Here
Perhaps the most telling detail comes from an unlikely source. A Samsung mobile executive told CNN that broader competition in the foldable category would help, saying “the more visibility there is on the category, the better.” That is not the language of a company feeling threatened. It is the language of a market leader who wants demand to grow fast enough to accommodate multiple players.
This matters because Apple entering the foldable space does not necessarily carve out Samsung’s share — it may expand the total addressable market. Apple buyers who would never consider a Samsung Galaxy Z series are a different segment entirely. If Apple succeeds, the category moves from niche to mainstream faster than Samsung could alone.
But there is a catch. Apple is entering as a follower. Samsung has iterated through multiple generations of foldable devices. The hinge, the crease, the durability — these are solved problems for Samsung, unknowns for Apple. A late entrant must differentiate on something beyond timing.
Siri AI Is the Real Bet
The foldable hardware draws attention. The software story may matter more. Apple is expected to reveal an AI-powered Siri refresh at the same event. This is where Ternus’s engineering background becomes relevant — not in the chassis design, but in how Apple integrates intelligence into the device experience.
Cook’s Apple won on ecosystem lock-in. Ternus’s Apple needs to win on relevance in an AI-native computing era. Siri has been the embarrassing gap in that strategy for years. An AI overhaul is not just a feature update — it is a statement about whether Apple can compete on intelligence rather than merely on privacy and integration.
A successful Siri reveal would reassure investors that Apple is not passively waiting for ChatGPT-style models to eat into its services business. A weak one would confirm the worst fears: that Apple is structurally behind in AI despite its massive computing advantage.
The Bear Case Is Simple
Ternus has never led an iPhone launch as CEO. Investors will evaluate his messaging, his product strategy, and his ability to build confidence during his first major public event in the role. A lukewarm reception will attract disproportionate attention precisely because the leadership transition is already a story.
The foldable iPhone faces a mature competitor in Samsung. If Apple’s device is perceived as competent but unremarkable — a safe, slow entry rather than a category-defining moment — the margin expansion thesis weakens. Buyers do not fold their phones for the sake of folding. They fold them for a reason Apple has not yet articulated.
What Happens Next
The September 9 event will not determine Apple’s trajectory for a decade. But it will set the tone for Ternus’s early months and signal whether the company’s next chapter is defined by cautious iteration or bold repositioning.
If the foldable iPhone lands well, if Siri AI feels genuinely intelligent rather than marketing-dressed, if Ternus commands the stage with the confidence of someone who understands both the hardware and the strategy — Apple’s stock could re-rate on the conviction that it is entering the next computing era on its own terms.
If none of that lands, the market will read a different story: a company that won by playing it safe, now scrambling to catch up in the categories that matter.
The first iPhone keynote without Tim Cook is not just a product launch. It is a leadership test.
