Two months into a war that has closed the Strait of Hormuz, sent oil prices above $100 a barrel, more than doubled jet fuel costs, disrupted global supply chains from semiconductor inputs to aluminium cans, and placed the global economy on watch for what energy analysts are now describing as a potential structural supply shock — America’s corporate earnings season is telling a story that is, by most measures, surprisingly confident.
It is not a uniform story. Twenty-four S&P 500 companies have withdrawn or cut their forecasts since the war began on February 28. Thirty-five have warned of financial hits. Thirty-five more have signalled upcoming price increases. The airlines are suffering. Procter & Gamble warned of a $1 billion profit hit in fiscal 2027. The Iran war’s economic fingerprints are visible on balance sheets and income statements across every sector that touches energy, packaging, logistics, or commodities.
But the aggregate signal from the first quarter of 2026, as it is emerging through the largest corporate reporting season in American financial history, is something the market did not fully expect: resilience. Broad, imperfect, hedged, and qualified — but genuine.
The Numbers That Tell the Story
The statistics assembled by FactSet as of April 24 make the Q1 earnings season one of the strongest in years, measured against the macro backdrop against which it is being delivered. Of the 28% of S&P 500 companies that had reported actual Q1 2026 results by that date, 84% beat earnings per share estimates — above the five-year average of 78% and the ten-year average of 76%. Companies were reporting earnings 12.3% above analyst estimates, compared to the five-year average beat of 7.3% and the ten-year average of 7.1%.
The blended net profit margin for the S&P 500 in Q1 2026 stands at 13.4% — the highest level FactSet has recorded since it began tracking the metric in 2009, above the prior quarter’s 13.2% and the year-ago 12.8%. S&P 500 earnings growth for the quarter is running at approximately 13.9% year-on-year, with analysts at LSEG having revised that estimate upward to 16.1% as of April 24 from 14.3% on February 27, the day before the war began.
David Morrison, senior market analyst at Trade Nation, put the mood bluntly: “It’s been an extraordinarily strong earnings season. The bullish signalling from CFOs and CEOs was necessary.”
The technology sector has provided the engine for much of that growth. Alphabet, Microsoft, Meta, and Amazon all reported Q1 results that beat expectations across revenue and earnings, driven by cloud computing, AI infrastructure demand, and digital advertising resilience. The Magnificent 7 are expected to deliver approximately 46% earnings growth in Q1, contributing nearly 80% of the total S&P 500 profit increase. For an index that includes airlines, consumer goods companies, and industrial manufacturers all absorbing oil shock costs, having the technology sector running this hot provides enormous headline-level insulation against sector-specific pain.
The Companies Making the Resilience Case
Beyond technology, the resilience story is being made by a diverse set of American businesses drawing on different competitive advantages to absorb the Iran war’s economic pressure.
Coca-Cola raised its full-year comparable EPS growth forecast to 8% to 9% from 7% to 8% after reporting Q1 revenue of $12.47 billion — beating the $12.24 billion consensus — with global unit case volume growing 3% across all four geographic segments. CFO John Murphy told Reuters that like PepsiCo, Coca-Cola had locked in commodity prices before the disruption began. “We are working hard with our bottling partners to deal with the implications of the situation in the Middle East,” he said. The hedging position bought time that most consumer goods companies do not have. Shares rose more than 5% on Tuesday.
General Motors raised its 2026 EBIT-adjusted guidance by $500 million, to a range of $13.5 billion to $15.5 billion, after reporting Q1 revenue of $43.6 billion and adjusted EPS of $3.70 — well above the LSEG estimate of $2.62. The guidance raise was driven partly by a tariff refund flowing from the US Supreme Court’s February ruling striking down IEEPA tariffs, which allowed GM to revise its gross tariff cost estimate for the year downward from $3.0 to $4.0 billion to $2.5 to $3.5 billion. GM did acknowledge that inflation in raw materials, chips, and logistics is expected to cut annual earnings by $1.5 billion to $2 billion — about $500 million more than it estimated late last year. But its US market position, described as “resilient” by executives, gave it enough room to raise guidance anyway. Shares jumped more than 4%.
Visa, which processes payments in more than 200 countries, reported that cross-border volumes were affected by the Iran war’s disruption of Middle Eastern economies but less so than feared, citing strong US domestic spending and continued e-commerce growth. The payment network’s business model — a toll on transactions rather than a holder of credit or inventory risk — provides natural insulation against the commodity and logistics costs affecting goods-heavy companies. Apple, reporting its first quarterly results of the Cook-to-Ternus transition period, delivered Greater China sales of $25 billion, up 35% year-on-year, ahead of analyst expectations, as the iPhone 17 cycle continued to outperform. Its net revenue of $102.7 billion for the quarter beat consensus.
The Sectors Where Resilience Runs Out
The pattern of corporate resilience is not uniform, and the Reuters review of company guidance actions since the war began makes the stress points clear.
Airlines are the most exposed sector by a significant margin. Jet fuel prices have nearly doubled since the end of February, wedging carriers between spiraling costs and tickets already pre-sold at lower fares. JetBlue reported a wider-than-expected first-quarter loss and announced plans to slow hiring, cut capacity, and raise fares. KLM cancelled 80 return flights from Schiphol. EasyJet posted a pretax loss guidance of £540 million to £560 million. Delta absorbed a $400 million fuel cost spike in the first two weeks of the war alone.
The consumer goods sector is the second pressure point. Procter & Gamble’s $1 billion profit warning for fiscal 2027 is the starkest single number in this earnings season’s Iran war ledger. The difference between P&G’s situation and Coca-Cola’s is not just hedging — it is petrochemical intensity. P&G’s products — plastic-packaged detergents, polymer-based personal care items, petrochemical-derived packaging across its entire range — carry a fundamentally higher oil price exposure than a beverage company whose primary inputs are water, flavouring, and aluminium cans.
Sodexo, the French catering and facilities management giant, posted a 32% decline in first-half operating profit and cut its full-year guidance to 3.2% to 3.4% margin from 4.7% — a collapse driven partly by the Iran war’s logistical disruptions to its food supply chains and partly by pre-existing operational failures that the war has accelerated. Vitol CEO Russell Hardy has estimated that the conflict has removed approximately 600 to 700 million barrels of cumulative oil production from global supply, with total losses expected to reach one billion barrels.
What Explains the Resilience and What Could End It
The resilience of Q1 corporate earnings despite the Iran war’s macro damage has three primary explanations.
The first is timing. The war began on February 28 — eleven weeks before the end of Q1 reporting. Commodity hedging positions, prior purchasing contracts, and inventory buffers established before the war meant that the first-quarter income statements of many companies reflected pre-war input costs for a significant fraction of the period. The damage from $100 oil will be more fully visible in Q2 and Q3 results than in Q1.
The second is technology sector dominance. The S&P 500’s earnings growth story is being written primarily by companies whose products are delivered digitally or whose revenue is driven by AI infrastructure spending — neither of which is meaningfully affected by the price of oil. When Alphabet, Microsoft, Meta, and Amazon collectively beat estimates by wide margins, they provide headline earnings growth that masks considerably more differentiated performance beneath the surface.
The third is corporate adaptation. Companies have spent years learning how to manage cost shocks through hedging, packaging redesign, pricing levers, and supply chain diversification. The playbooks that consumer goods companies developed during the 2021 to 2023 inflation shock — smaller pack sizes, targeted price increases, supplier renegotiations — are being redeployed in 2026 with institutional muscle memory that did not exist during previous commodity cycles.
The risk to this resilience is straightforward: if the Strait of Hormuz remains closed beyond what hedging positions cover, if oil sustains at or above $100 through Q2 and into Q3, and if consumer spending begins to crack under the combined weight of fuel costs and inflation — the Q1 resilience narrative becomes a Q2 earnings warning season. The ceasefire that expired Wednesday April 21, the Islamabad peace talks that remain uncertain, and the Hormuz traffic that was at a trickle as recently as this week are all live variables.
The companies reporting this week and next are projecting confidence. The next ninety days will determine whether that confidence was earned or merely borrowed.
