** Shares in Turkish energy engineering firm Girisim Elektrik GESAN.IS rise more than 6% as strong first-quarter margins and backlog outweigh non-operating hits to profit
** Q1 net profit fell to 181.7 million lira from 540 million lira a year earlier, while revenue increased to 6.8 billion lira from 5.2 billion lira
** EBITDA rose 103% to 2.3 billion lira, with gross margin expanding sharply to 39.6%, supported by a higher share of medium- and high-voltage products, says Global Menkul Degerler
** The brokerage highlights a sharp rise in order advances and deferred revenues, pointing to a strong backlog and sustained business activity in the coming quarters
** It adds the drop in net profit was largely driven by monetary losses, weaker foreign-exchange income and higher deferred tax expenses rather than core operations
* Shares are second best performers on Turkey's main BIST 100 index .XU100. Today's rise brings YTD gains to over 33%
