Investors' hopes for luxury demand to recover have been dashed by the conflict, which has dented Dubai mall sales and sent energy prices soaring, hitting consumer confidence.
Hermes, which carefully controls production and sales to maintain exclusivity, has been the most resilient company in an industry-wide slowdown, but even it was not immune to the conflict's impact.
LVMH and Kering this week reported sales were hit by the war.
Overall sales of products including Birkin and Kelly bags, silk scarves and perfume rose by 5.6 per cent in currency-adjusted terms, Hermes said, lower than a Visible Alpha analyst consensus of 7.1 per cent growth.
Sales in the Middle East region fell six per cent in currency-adjusted terms to 160 million euros ($A264 million), from 185 million euros in the first quarter in 2025.
"We had very good growth, double-digit growth in January and February and then the month of March was an abrupt halt," said chief financial officer Eric du Halgouet, adding that sales in luxury malls in Dubai and other Gulf shopping hubs dropped by 40 per cent in March.
Though only accounting for 4.4 per cent of sales, the Middle East was the fastest-growing region for Hermes in 2025.
Hermes, which caters to the ultra-wealthy with handbags over $US10,000 ($A14,000), said a drop in tourist numbers had hit sales in concession stores at airports and in the Middle East, as well as in Britain, Italy and Switzerland, where Gulf shoppers are a key driver.
Sales in France declined 2.8 per cent due to the drop in tourism.
In Asia, the biggest region by sales for Hermes, revenue grew by just 3.5 per cent in currency-adjusted terms as air travel disruption also had an impact there, du Halgouet said, particularly Singapore and Thailand.
The US was a bright spot, with currency-adjusted sales up 17.2 per cent.
Currency fluctuations took 290 million euros off Hermes' revenue in the quarter, leading to a one per cent drop in reported sales to 4.07 billion euros, from 4.13 billion euros a year ago.
