The Iran war is now showing up in hotel companies’ earnings — and executives say the worst may still be ahead. Marriott International’s Middle East RevPAR fell 43% in the second quarter. About 35% of Marriott’s full-year Middle East revenue is typically booked in Q4, CFO Jennifer Mason told analysts on an earnings call Monday. “We still see very strong global demand other than the Middle East,” Mason said. Marriott said construction delays on new Middle East hotels will push annual net room growth to the low end of its previously guided 4.5%-5% range.
