Fourth quarter 2018 financial results:
Fourth quarter 2018 total revenues were $1.8 million, a 6% increase over last year’s fourth quarter revenues of $1.7 million and within the range of guidance.
Product revenues, primarily T2Candida Panel and T2Dx Instrument sales, were $1.3 million, level with last year’s fourth quarter product revenues and were driven by growing T2Candida Panel sales and the timing of T2Dx Instrument sales. T2Bacteria Panel sales are just commencing to ramp after our July 2018 launch due to hospital new diagnostic’s validation protocols of 3 to 6 months.
Research revenues were $0.5 million compared to $0.3 million in last year’s fourth quarter.
Costs and expenses, excluding costs of product revenue, were $9.8 million, compared to $9.7 million in last year’s fourth quarter and were $1.0 million below the low range of guidance and include depreciation andnon-cash stock option compensation and restricted stock unit, or RSU, grants of $3.0 million in the fourth quarter compared to $1.8 million in last year’s fourth quarter, an increase primarily due to the vesting of performance-based RSUs.
Operating margins were a loss of $13.6 million, compared to a loss of $14.4 million in last year’s fourth quarter.
Net interest expense and other income was $1.6 million compared to $3.8 million in last year’s fourth quarter and decreased due to the absence of a derivative charge in 2018.
Our net loss was $15.1 million, ($0.34) per share, compared to a net loss in last year’s fourth quarter of $18.2 million, ($0.51) per share. Weighted average shares outstanding were 44.1 million compared to 35.7 million in last year’s fourth quarter.
Our cash and cash equivalents were $50.8 million at December 31, 2018. We believe our cash and financing sources are sufficient through the first half of 2020.
2018 financial results:
We delivered 14 new system contracts in the fourth quarter of 2018 and 25 in the second half of 2018, which was at the high end of our guidance.
On our last call, we estimated that these instrument were expected to provide access to at least 75,000 patients suspected of sepsis in the second half of the year, and the fourth quarter achievement alone of more than 80,000 exceeded that goal. The number of high-risk patients is important as it represents the current existing market opportunity for the T2Candida and T2Bacteria Panels if every patient at hospitals under contract were tested at the time they showed symptoms of infection. However, this metric is becoming increasingly difficult to accurately track and report, and ultimately will become less meaningful as we expand our installed base and drive adoption into this high-risk population, which will be reflected in our utilization and recurring T2Bacteria and T2Candida Panel sales. Therefore, we will discontinue this metric in 2019.
