Apple's best March quarter on record confirms the iPhone 17 supercycle is real

Apple's fiscal second quarter results do not require interpretation. Revenue of $111.2bn, up 17% year on year. Earnings per share of $2.01, up 22%. Gross margin of 49.3%, nearly a full percentage point above analyst expectations. Double-digit growth in every geographic segment and every product category. March quarter records for revenue, iPhone sales, earnings per share and operating cash flow.

These are not incremental gains. They follow a record-breaking holiday quarter in which Apple posted $143.8bn in revenue and $85.3bn from iPhone alone. Taken together, the first half of Apple's fiscal 2026 represents the strongest six-month stretch in the company's history, driven by an upgrade cycle that Wedbush Securities analyst Dan Ives has called a once-in-a-decade event.

The upgrade wave that arrived

iPhone revenue of $57bn rose 22% in the quarter, the second consecutive period of growth above 20%. CFO Kevan Parekh said the iPhone 17 family is the most popular lineup Apple has produced. Customer satisfaction in the US reached 99%. The company set March quarter records for both upgraders and first-time buyers.

The scale of the cycle becomes clearer in context. More than 315 million iPhones had gone four or more years without an upgrade heading into this fiscal year, according to JPMorgan research. The iPhone 17 is the first generation that requires 12GB of RAM as standard in the Pro models, making it the entry point for the full Apple Intelligence feature set. That hardware requirement turned a routine product refresh into a forced upgrade for anyone who wanted access to on-device AI.

Cook told analysts that demand exceeded supply. The constraint was not consumer appetite but physical availability. TSMC's advanced 3nm chip nodes, which produce Apple's A19 processors, are shared with the AI semiconductor supply chain. Cook said iPhone supply constraints were driven by competition for those production lines. Without those bottlenecks, revenue would have been higher.

China stops being a problem

Greater China revenue of $20.5bn, up 28%, was the stand-out number in the report. Cook said the first half of the fiscal year saw 33% growth in China. The iPhone was the top-selling smartphone model in urban China. The Mac mini was the top-selling desktop. The MacBook Air was the top-selling laptop.

This matters because China had been the persistent weak spot in Apple's story. Huawei's resurgence in the domestic market, combined with nationalist buying patterns and aggressive pricing from local competitors, had produced several quarters of declining sales. Wall Street had lowered expectations accordingly.

The turnaround was driven by a combination of factors. Apple locked in long-term memory supply agreements that allowed it to hold pricing while competitors were forced to raise prices in response to a global shortage of DRAM and NAND chips. Subsidies on e-commerce platforms helped push the base model iPhone 17 into price-sensitive segments of the market. And the iPhone 17's feature set, particularly its camera system and AI capabilities, proved compelling enough to pull buyers away from Huawei's Pura 90 series.

Wedbush's Ives, who carries the Street's most aggressive price target on Apple at $350, described the China result as evidence that the region has shifted from headwind to tailwind.

Margins hold where they should not have

Gross margin of 49.3% came in above Apple's own guidance range of 48% to 49% and ahead of the 48.4% consensus. This was not supposed to happen. Memory prices have been rising across the industry as AI infrastructure spending consumes available supply of high-bandwidth memory. Meta and Microsoft both cited rising memory costs as a factor in their increased capital expenditure forecasts this week.

Apple absorbed the impact without raising consumer prices, in part because of those earlier supply agreements. But Cook warned the situation will worsen. He told analysts to expect "significantly higher memory costs" in the June quarter and said the cost pressure would intensify through the rest of the fiscal year.

The services business provided additional margin support. Revenue of $30.98bn, up 16%, set another all-time record. With an installed base now exceeding 2.5 billion active devices, services revenue has structural tailwinds that are difficult to reverse. The segment's margins, which run above 70%, continue to lift the overall business as its share of revenue grows.

The transition and what follows

This was one of Tim Cook's final earnings calls. On 1 September, John Ternus, the hardware engineering chief who has been at Apple for 25 years, will take over as CEO. Cook will become executive chairman.

Ternus joined the call for the first time and offered brief remarks, pledging continuity on financial discipline. He described the product roadmap ahead as the most exciting of his career at Apple but declined to provide specifics. Cook, for his part, was characteristically measured. He described the Google partnership on Gemini for Siri as going well, said AI investment would increase on top of normal product roadmap spending, and confirmed that any tariff refunds received would be reinvested in US manufacturing.

R&D spending rose 33% in the quarter to $11.4bn, a signal that Apple is accelerating investment even as it delivers record profits. The June quarter guidance of 14% to 17% revenue growth was well above the 9.5% the Street had expected.

Apple authorised a further $100bn in share buybacks and raised the dividend by 4%. Wedbush maintained its outperform rating and $350 price target.

What the numbers say

The results confirm that the iPhone 17 cycle is the strongest since the iPhone 12 introduced 5G in 2020, and arguably the strongest since the iPhone 6 created the large-screen category in 2014. Two consecutive quarters above 20% iPhone growth, in a product category that many investors had written off as mature, rewrites the narrative around Apple's hardware business.

The risk is visible. Memory costs are rising, tariff policy remains uncertain, and TSMC capacity constraints could cap unit volumes in the near term. But the margin structure is holding, the services flywheel is producing record revenue, and China is growing at 28%.

Cook is leaving with the company in the strongest position it has occupied in years. The question for investors is whether Ternus can sustain it.
