GenMark

The firm has completed submissions for all three of its ePlex panels for diagnosis and management of bloodstream infections that can lead to sepsis.

Smaller multiplex molecular panels of five or fewer targets will be covered, while a determination of gastrointestinal panel coverage is expected soon.

The company beat the consensus Wall Street estimate on the top line but missed it on the bottom line. It placed 39 net new ePlex analyzer during the quarter.

It is the first of three ePlex molecular multiplex panels for the diagnosis and management of bloodstream infections that can lead to sepsis.

In 2018, the company expects to place between 140 and 170 new ePlex analyzers, and an annuity per ePlex in the $100,000 to $120,000 range.

The decline matched the struggles of the broader stock market, though bright spots could be found with GenMark, Quidel, and NanoString all having good months.

The GenomeWeb Index outperformed the Nasdaq Biotechnology Index, which lost 5 percent in February, but lost the same amount as the Dow.

Guidance for 2018 placements of ePlex respiratory testing systems is lower than analysts’ estimates, but the firm communicated remedies for adoption challenges.

On a conference call following the release of the earnings, the firm's CEO guided for lower 2018 ePlex placements than had been expected by analysts.
