Overture Acquisition Corp., trading under the ticker NLX, was a blank check company that filed an S-4/A amendment with the SEC on January 8, 2010, signaling it had entered the late stages of executing a business combination with an identified target. The S-4/A form, an amendment to the original merger registration statement, is typically filed as a SPAC nears shareholder vote, making Overture one of the earlier SPACs to advance through the deal-closing pipeline in the post-financial-crisis environment of early 2010. The company operated in a period when SPAC completions faced elevated scrutiny following the 2008 market downturn.
