Signet Jewelers raised its fiscal 2027 adjusted earnings-per-share outlook to $10.45-$12.15 from $9.20-$11 after reporting second-quarter adjusted EPS of $2.19, nearly 30% above the $1.69 estimate cited in the latest report and marking its sixth consecutive quarterly earnings beat. An earlier estimate in the existing record was $1.74. Sales fell 0.5% to $1.528 billion, broadly matching expectations, while comparable-store sales rose 2.2%. GAAP diluted EPS was $1.33, compared with a loss of 22 cents a year earlier, and adjusted operating margin expanded to 7% from 5.6%. Signet maintained its annual sales forecast of $6.7 billion-$6.9 billion and announced plans for a $125 million accelerated share repurchase after buying back 1 million shares for $87 million during the quarter. Shares rose 19.62% to $98.89, with the move potentially amplified by short interest exceeding 18% of the public float. Management said its Bread Financial agreement could generate more than $1 billion of incremental revenue and operating income through 2035, including $200 million-$250 million over the next 36 months, without loss sharing.
