Thermo Fisher Scientific Inc. agreed to acquire rival laboratory equipment manufacturer Life Technologies Corp. for $13.6 billion in cash and assumed debt on April 15. The target’s stockholders will receive $76 a share, a 38 percent premium to Life Technologies’s closing price on January 17, the day before it announced that it was engaging in a strategic review.

The companies hope to close the deal early next year pending approvals from regulators and Life Technologies shareholders.
