Domino's Pizza stock falls on disappointing sales — and CEO thinks more chains will follow

domino's pizza stock dropped 10% monday morning after reporting u.s. same-store sales growth of just 0.9% — well below the 2.3% analysts expected. ceo russell weiner told cnbc "we're not happy with it." the chain also cut its full-year forecast to low-single digit growth, down from an earlier projection of 3%. weiner said he expects more fast-food chains to report similar headwinds from winter weather and weak consumer sentiment, which took a dive in march due to spiking fuel prices from the u.s.-israeli war with iran. "one of the bad things about reporting first is you don't get to hear about anybody else," he said. domino's faced stiffer competition during the quarter. papa john's and pizza hut both matched its $9.99 "best deal ever" promotion, and little caesars undercut domino's $6.99 mix & match deal with a $5.99 version. weiner still expects both rivals to report same-store sales declines. shares have lost nearly a third of their value over the last year, with market cap at roughly $11.2 billion.
