Medical device maker Alphatec Holdings Inc. posted a larger first-quarter loss on Monday as it completed the purchase of Scient'x Groupe SAS.

The parent of Alphatec Spine said it lost $4.7 million, up from $4.4 million a year ago. Because the company now has more stock on the market, its per-share loss was unchanged at 9 cents. Excluding costs related to the Scient'x deal and restructuring costs, the company said it lost $200,000 — or broke even on a per-share basis.
