Sweden's Securitas second-quarter core profit rises but misses estimate

July 24 (Reuters) - Sweden's Securitas, one of the world's largest security services providers, reported lower-than-expected second-quarter core profit on Friday, weighed down by weak organic sales growth.

• Securitas' operating earnings before amortisation (EBITA) rose to 2.82 billion Swedish crowns ($289.13 million) in April-June from 2.80 billion crowns a year earlier, but missed analysts' average forecast of 2.91 billion crowns in a poll provided on its website.

• Organic sales growth was 0% in the quarter, down from 5% a year earlier, while adjusted organic sales growth was 3%.

• Operating margin increased to 7.50% from 7.30% a year earlier.

• "We delivered an improved adjusted operating margin in the second quarter, reaching 7.6%, driven by both the technology and solutions and the security services business lines," CEO Magnus Ahlqvist said in a statement.
