RUTHERFORD, N.J., November 9, 2017 — Cancer Genetics, Inc. (Nasdaq: CGIX), a leader in enabling precision medicine for oncology through molecular markers and diagnostics, today announced financial and operating results for the third quarter and nine months ended September 30, 2017.

Mr. Panna Sharma, President and CEO of CGI commented, “During the third quarter of 2017 we continued to advance our business growth through execution of targeted strategic initiatives. We are pleased to have delivered a record quarter of revenue along with a significant bottom line improvement, and are committed to achieving profitability in the near-term.

“Cancer Genetics continues to be a leader in working with biopharma companies to realize the potential of precision oncology and to bring new, life-saving therapies to patients across a wide range of oncology indications. Our 134% increase in contracted revenue is illustrative of the high value the biopharma industry puts on the expertise that CGI brings to drug development, as well as the strategic focus of the Company to be the premier partner for drug discovery and development in oncology. We are extremely proud to be actively working with nine of the top ten biopharma companies, which is a testament to our unique business model and capabilities.”

Mr. Sharma continued, “Our acquisition of vivoPharm is an excellent example of our commitment as we seek to broaden and deepen our business, reduce the timeline to bring new cancer therapies to the marketplace and increase our value to the oncology community. We believe these efforts will also create value for our shareholders. The integration of the vivoPharm acquisition is on-track and will deliver a full quarter of results and additional revenue in the fourth quarter of 2017. This acquisition is another milestone in the execution of our strategy to develop the Company into the bench-to-bedside leader in personalized oncology.

“We will continue to drive our growth initiatives as we move toward increasing our market share and achieving profitability. We believe we are optimally positioned to grow our business as we become the partner of choice for oncology drug developers, cancer centers and clinicians.”

THIRD QUARTER 2017 FINANCIAL RESULTS

The company reported total revenue of $8.0 million for the third quarter of 2017, an increase of 19% compared to revenue of $6.8 million in third quarter of 2016. The revenue increase was

primarily driven by increased revenue in each line of business including Biopharma Services, Clinical Services, and Discovery Services, including the impact of the vivoPharm acquisition which contributed $0.8 million in the second half of the third quarter, since the date of acquisition.

Biopharma Services revenue totaled $4.2 million in the third quarter, compared to $3.8 million during Q3 2016, an increase of 10%. Additionally, the company increased the number of clinical studies and trials it is supporting to 191, up 59% from Q3 2016.

Clinical Services revenue increased 7% in the third quarter of 2017 over the same period in 2016, from $2.7 million to $2.9 million. The growth was driven by an increase in clinical test volumes from 7,334 in Q3 2016 to 7,373 in the third quarter of 2017.

Discovery Services contributed an additional $1.0 million in revenue for the third quarter of 2017, a 280% increase over Q3 2016, driven by the addition of vivoPharm revenue and significant demand for discovery solutions by research institutions where next-generation sequencing is combined with novel bioinformatics analysis. Discovery Services for global customers are performed in India, Australia, China and the U.S.; and provides genomic and bioinformatics support for global discovery and pre-clinical initiatives.

Gross profit margin increased to 42.9% or $3.4 million compared to 34.2% or $2.3 million in Q3 2016. The gross margin improvement was primarily driven by improved staff utilization as the company continues to optimize the integration of prior acquisitions and stronger purchasing power as lab operations expand.

Total operating expenses for Q3 of 2017 were $6.6 million, an increase of 4% compared to $6.3 million during Q3 2016.  While revenues increased by 19% in the comparable periods, operating expenses remained relatively flat by gaining operating leverage through staffing efficiencies and absorption of fixed costs.

Net loss was $0.6 million or $0.15 per share for the third quarter of 2017, compared to a net loss of $3.7 million or $0.23 per share for the third quarter of 2016, primarily impacted by a non-cash adjustment of $2.8 million related to the valuation of derivative warrant liabilities.

Cash and cash equivalents totaled $4.8 million as of September 30, 2017, compared to $9.5 million as of December 31, 2016. On August 14, 2017, the Company entered into a common stock purchase agreement with Aspire Capital Fund, LLC, through which Aspire Capital has committed to purchase up to an aggregate of $16 million of CGIX common shares (of which $3 million was drawn on August 15, 2017, and filed in Form 8-K) over a two-year period, subject to certain transaction-related conditions.

NINE MONTHS 2017 FINANCIAL RESULTS

For the first nine months of 2017 revenues were $21.6 million as compared to $19.8 million for the first nine months of 2016, a 9% increase.  The Company reported a gross margin in the nine month period ended September 30, 2017 of 41% compared to 35% in the same period last year,

an improvement of 6 percentage points.  Total operating expenses declined $2.3 million or 12% to $17.9 million for the nine months ended September 30, 2017.  Net loss was $13.0 million or $0.65 per share for the nine month period of 2017, compared to a net loss of $13.0 million or $0.88 per share for the corresponding year ago period.
