Apple is preparing for its first CEO transition in 15 years. On September 1, 2026, John Ternus, the company’s longtime Senior Vice President of Hardware Engineering, will step into the top role, while Tim Cook transitions to Executive Chairman. Ternus, a mechanical engineer who joined Apple in 2001, brings deep expertise in product design and hardware development, including the iPhone, iPad, Apple Watch, AirPods, and the successful transition to Apple silicon. Seen as more decisive than the consensus-driven Cook, he is expected to inject a bolder, product-focused approach. Yet he inherits a company at a critical juncture, facing slowing growth in core products, fierce competition in emerging technologies, and complex external pressures.

Here are the biggest challenges awaiting Ternus:

### 1. Accelerating Apple’s AI Strategy and Reviving Siri
Artificial intelligence stands as the most urgent priority. Apple’s “Apple Intelligence” features have been criticized for lagging behind offerings from Google, OpenAI, and Microsoft. The long-awaited overhaul of Siri has encountered repeated delays, forcing the company into partnerships with Google (Gemini) and OpenAI (ChatGPT) rather than relying solely on in-house models.

Ternus must deliver a compelling, privacy-centric AI experience capable of driving iPhone upgrades and new subscription revenue. Broader questions loom around agentic AI systems, potential ventures into robotics or embodied intelligence, and the risk of overcommitting resources to what some view as an AI investment bubble. Success in this area will be essential to maintaining Apple’s premium brand perception in an increasingly AI-driven consumer market.

### 2. Sparking Meaningful Product Innovation and Identifying the “Next Big Thing”
Innovation has been a hallmark of Apple’s success, but recent years have seen perceptions of stagnation, especially after the mixed reception of the Vision Pro. With iPhone replacement cycles lengthening and the device still accounting for roughly half of revenue, Ternus needs to evolve the core lineup while exploring new categories.

Rumored projects such as a foldable iPhone, advanced AR glasses, smarter home devices, or even touchscreen Macs could define his early tenure. As a proven “product guy,” Ternus has the hardware credentials to lead these efforts, but he must demonstrate visionary leadership reminiscent of the Steve Jobs era to reignite excitement and growth.

### 3. Managing Regulatory Scrutiny and Geopolitical Risks
Apple continues to battle significant antitrust and regulatory challenges worldwide. Ongoing lawsuits from the U.S. Department of Justice and the European Union target the company’s App Store policies, ecosystem lock-in, and high commissions. Potential fines, contempt rulings, and court decisions could reshape how Apple operates.

Ternus will also need to navigate complex international relations, including U.S. trade policies and tariffs, tensions with China over supply chains and data rules, and compliance with evolving EU regulations. While Cook excelled at global diplomacy, Ternus must quickly build similar relationships, with Cook’s continued involvement as chairman providing valuable support.

### 4. Reducing Dependence on China and Strengthening Supply Chains
Despite efforts to diversify manufacturing to India and Vietnam, Apple remains heavily reliant on China for production and a significant portion of its revenue. Geopolitical tensions, potential tariffs, local competition from companies like Huawei, and regulatory hurdles continue to pose risks.

Ternus must balance faster diversification with the need to protect margins, quality, and timely product launches—a delicate act that could influence the company’s cost structure and resilience for years to come.

### 5. Retaining Top Talent and Shaping Apple’s Culture
Recent departures and shifts among senior executives, including in AI and operations roles, highlight the importance of leadership stability. Ternus, younger than some of his peers, will need to retain stars such as Craig Federighi while attracting fresh talent in AI and hardware from competitors.

Establishing his own leadership style and potentially refreshing the executive team will be crucial to maintaining Apple’s innovative edge and distinctive culture during this transition.

### A Pivotal Moment for Apple
Beyond these core issues, Ternus must sustain strong services growth, reinforce brand momentum, and prove that Apple’s deliberate, high-quality approach can thrive in the fast-paced AI era. He enters the role with significant advantages: a loyal customer base, substantial cash reserves, a powerful ecosystem, and the benefit of Cook’s mentorship.

As Apple approaches its 50th anniversary, Ternus’s success will hinge on balancing the company’s methodical culture with the urgency demanded by technological disruption. Early indicators—such as updates at WWDC 2026 and major hardware launches in late 2026 and 2027—will offer the first clear signals of how effectively he can steer Apple into its next chapter. The stakes are high, but so is the opportunity to write a new success story for one of the world’s most valuable companies.
