Guess? Inc yesterday (4 August) filed record second quarter financial results in which net earnings soared by 81.5% on double digit revenue increases across all businesses, and raised its full year guidance.

For the three months to 4 August, the Los Angeles, California-based jeanswear and sportswear brand reported net earnings of $37.5m, up from $20.6m for the same period last year.

Diluted earnings per share increased 81.8% to $0.40 per share in the current quarter versus $0.22 per share a year ago.

Paul Marciano, chief executive officer, said the results reflect "the continued strength of the Guess brand, the success of our ongoing investments in long-term initiatives, such as Europe, Asia, and our accessories lines, and the consistency with which we are growing our business in North America and abroad."

For the six month period, net earnings were up 76.7% to $73.0m from $41.3m, and diluted earnings per share increased 73.3% to $0.78 per share versus $0.45 per share last time.

Guess now expects diluted earnings per share to be in the range of $1.79 to $1.84 for the fiscal year ending 2 February 2008, up from previous estimates of $1.75 to $1.80, and net revenues to range from $1.56bn to $1.60bn.
