BASKING RIDGE, N.J., March 27, 2019 — electroCore, Inc. (Nasdaq: ECOR), a commercial-stage bioelectronic medicine company, today announced fourth quarter and full year 2018 financial results and provided an operational update.

Fourth Quarter 2018 and Recent Highlights

• Generated in excess of 5,800 gammaCore^® prescriptions in the fourth quarter of 2018, an increase of more than 30% from the third quarter 2018

• Generated approximately 15,000 gammaCore^® prescriptions in 2018

• Over 1,800 unique prescribing physicians through the fourth quarter of 2018, up from approximately 1,500 in the third quarter 2018

• Commercial payer coverage together with the Federal Supply Schedule increased covered lives to 53 million

“During the fourth quarter, we continued to execute on our commercial growth plan, led by our ongoing progress toward increasing covered lives through productive discussions with national and regional payers,” said Frank Amato, Chief Executive Officer of electroCore. “Notably, our fourth quarter results do not reflect the addition of covered lives from CVS Caremark, Highmark and the recently announced Federal Supply Schedule contract, all of which commenced reimbursement of gammaCore^® beginning in the first quarter 2019. Our leading indicators in our approved indications of migraine and cluster headache – which together represent a four billion dollar market opportunity – are very strong, and coupled with our R&D initiatives targeting additional indications in headache conditions and rheumatoid arthritis, we believe we have established a solid foundation from which to drive future growth. Vagus nerve stimulation represents an effective, drug-free andnon-invasive alternative treatment modality that we believe has broad clinical utility across a range of underserved medical conditions, and we intend to make gammaCore^® the therapy of choice for patients who stand to benefit from this innovative therapy.”

Fourth Quarter and Full Year 2018 Financial Results

For the quarter ending December 31, 2018, electroCore reported net sales of $368 thousand, an increase of $134 thousand from the fourth quarter of 2017 and an increase of $217 thousand from the third quarter of 2018, reflecting increased sales of gammaCore Sapphire.

Total operating expenses for fourth quarter of 2018 were $15.9 million, which is an increase of $8.4 million compared to the same period in 2017 and an increase of $2.3 million from the third quarter of 2018.

For the full year, net sales were $993 thousand, a 22% increase as compared to $811 thousand for the full year 2017. This increase in net sales is attributable to higher prescriptions as a result of the full commercial launch of gammaCore in the U.S.

Total operating expenses were $55.0 million for the full year 2018 as compared to $25.9 million for the full year 2017. The increase in operating expense was driven primarily by costs related to the expansion of the company’s sales and marketing functions.
