On June 30, 2018, the Company purchased select assets and liabilities from Integrated Diagnostics, Inc. (Indi) for total consideration of $27.6 million, consisting of $8.0 million in the Company’s Series G Preferred Stock and contingent consideration with an initial estimated fair value of $19.6 million. The acquisition was accounted for as a business combination and resulted in goodwill of $14.2 million representing expected synergies, including increases in future revenues as a result of expansion of the acquired technology into additional markets, and lower operating expenses.

The contingent consideration arrangement requires additional consideration to be paid by the Company to Indi upon attainment of a three-consecutive month gross margin target of $2.0 million within the seven-year period after the acquisition date. If the gross margin target is met, the Company is required to issue 2,520,108 shares of common stock. For the six months following the achievement of the gross margin target, Indi has the option to require the Company to redeem these common shares for $37.0 million in cash over eight equal quarterly installments. If Indi elects to not exercise its option, the Company has 12 months to repurchase the common stock in two equal and consecutive quarterly cash installments totaling $37.0 million.
