EA [NASDAQ: ERTS] has announced its Q1 FY10 financials, which reveal EA Mobile sales were $50 million for the three months ending June 30, 2009.

Compared to its sales of $44 million in Q1 FY09, this is up 14 percent year-on-year.

Compared to the quarter ending March 31 2009, sales were up 2 percent.

Unlike retail game sales, mobile sales tend to be less cyclical, making a quarter-on-quarter comparison more relevant in terms of spotting trends.

Indeed, while still increasing, the rate of growth of EA Mobile's quarterly sales has lessened from $47 million in Q3 FY03, to £49 million in Q3, and $49 million again Q4 FY09.

EA Mobile's total sales for FY09 were $189 million.

All these figures are provided using the standard Generally Accepted Accounting Principles (GAAP).

During its Q1 FY10, EA Mobile's key titles included The Sims 3, tie-in games for the Star Trek and X-Men Origins: Wolverine movies, as well as casual licenses such as Trivial Pursuit and Scrabble.

EA Mobile retains its crown as the largest mobile game publisher.

French rival, Gameloft's revenue for the same period (its Q2) was €29.3 million (around $40 million), and five percent of that total included WiiWare and DSiWare downloads.

Overall, EA's revenues were down 20 percent to $664 million under GAAP, which includes the impact of deferred revenue adjustments. They were up 34 percent to $816 million under non-GAAP.

The difference between GAAP and non-GAAP is non-GAAP is used to strip out one-off costs and income to try and make year-on-year comparisons easier.

The GAAP net loss for the quarter was $234 million compared to a net loss of $95 million year-on-year. Non-GAAP net loss was $6 million as compared with a non-GAAP net loss of $135 million year-on-year.

Demonstrating the impact on the credit crunch on traditional retail games, trailing-twelve-month cash flow was $25 million as compared to $239 million a year ago.

EA currently has $1.8 billion in cash, cash equivalents and short-term investments.
