Apple's new CEO John Ternus faces his first product keynote, and Wall Street's judgment

John Ternus walks onto the stage at the Steve Jobs Theater on Apple Park's campus in Cupertino on Wednesday for his first product keynote as chief executive, eight days after formally succeeding Tim Cook. The event, titled "Surprise and shine" and scheduled for 10 a.m. Pacific time, is expected to introduce Apple's first foldable iPhone alongside an updated iPhone 18 Pro lineup — a launch that doubles as the market's first extended look at how the company's post-Cook era will be run.

Apple confirmed the leadership change in an April newsroom announcement and in a corresponding filing with the Securities and Exchange Commission, which set September 1 as the effective date for Cook's move to executive chairman and Ternus's elevation to chief executive and a seat on the board. Arthur Levinson, previously board chairman, became lead independent director on the same date. Apple's own event notice confirms Wednesday's keynote is the first Apple has held since the transition took effect.

A hardware engineer's turn at the microphone

Ternus, 50, joined Apple's product design team in 2001 and has spent his career on the hardware side of the company, rising to vice president of hardware engineering in 2013 and senior vice president in 2021. He holds a mechanical engineering degree from the University of Pennsylvania and has been publicly credited with development work on the iPad, AirPods, iPhone, Mac and Apple Watch, according to Apple's own biography of him and reference material compiling his 25-year tenure. He replaces Cook, who ran Apple for fifteen years and oversaw its growth from a company worth roughly $350 billion when he took over in 2011 to one that briefly touched a $5 trillion market valuation in July, the second public company ever to reach that mark. Cook, in the April announcement, said Ternus "has the mind of an engineer, the soul of an innovator, and the heart to lead with integrity and honor." Levinson said the board considered Ternus "the best possible leader to succeed Tim."

Wednesday's keynote is the first time a chief executive other than Cook has run Apple's signature autumn product event since 2011, and it comes with none of the usual grace period. Apple's fiscal fourth quarter closes at the end of September, meaning the iPhone lineup Ternus introduces this week will define the company's results, and his own performance, before he has completed two full months in the job.

Pricing tests a new chief executive

The most immediate business question hanging over the event is price. Rising memory-chip costs industry-wide have squeezed hardware margins across the smartphone and PC sectors this year, and KeyBanc Capital Markets warned clients on Sunday that Apple faces a difficult trade-off as a result. Analyst Brandon Nispel's note projected the iPhone 18 Pro could open at $1,249, a $150 increase, with the Pro Max rising $200 to $1,399, and pegged a starting price near $2,199 for the first foldable model, widely expected to carry the "iPhone Ultra" name. Other estimates, including one cited by Fortune, put the foldable's starting price above $2,000 regardless of exact configuration.

Apple faces a choice to "raise prices broadly to offset gross margin pressure, which could hurt unit volumes and trigger sticker shock, or raise prices more selectively" — either path inviting closer scrutiny of margins and future increases, KeyBanc's note argued.

KeyBanc has held a rare Underweight rating on Apple stock with a $250 price target, well below where shares have traded in recent weeks. The firm's research projects iPhone 18 lineup builds of roughly 80 million units across the fiscal fourth quarter and the following quarter, down from about 91 million units a year earlier, a decline it attributes partly to Apple skipping a base iPhone 18 model this cycle and to demand risk from higher prices.

Apple shares have historically softened in the days immediately following iPhone reveal events even when they later recovered, and this week has offered an early test of that pattern. According to trading data compiled by stock-market data provider StockAnalysis, Apple stock closed at $316.22 on Tuesday, down 1.17% for the session, as broader markets fell on rising oil prices and interest-rate concerns. That is down from $328.21 the prior Thursday, though the stock had jumped 2.61% on September 1, Ternus's first day formally in the chief executive role.

The unresolved question is software, not hardware

Ternus's hardware pedigree is, to some investors and analysts, precisely the source of unease. Apple has spent nearly two years working to overhaul Siri, delaying the project multiple times before striking a deal to run an upgraded version of the assistant on Google's Gemini artificial-intelligence models rather than technology built in-house. An overhauled Siri beta is expected to arrive alongside this week's hardware, according to reporting cited by PYMNTS, but the company has yet to show it can build a leading AI product of its own rather than distribute a rival's. Cook himself told investors earlier this year that Apple did not yet have "a complete plan" for the computing costs the AI race demands.

That leaves Ternus, an engineer who built his reputation on physical products, to answer a question that is now mostly a software and business-model one: whether Apple can turn artificial intelligence into a revenue driver rather than a licensing expense, at the same time regulators are pressing on two of its most reliable profit centers, the App Store's commission structure and its roughly $20 billion-a-year search-placement agreement with Google, which remains subject to a Justice Department appeal.

What happens next

Cook is expected to attend Wednesday's event as executive chairman but not to appear on stage, leaving the full presentation to Ternus for the first time. Apple typically opens pre-orders for newly unveiled iPhones within days of a September keynote, with general availability following roughly a week and a half later, timing that would put both events in the back half of September this year. Apple's fiscal fourth-quarter earnings call, expected in late October, will be the first quarterly results Ternus reports as chief executive and the first hard data point on how the pricing decisions unveiled this week affected demand. Until then, Wednesday's keynote — and the initial market reaction to it — stands as the clearest signal yet of how investors are pricing the transition from Cook's fifteen-year run to Ternus's opening chapter.
