ABOUT THIS PROSPECTUS

This prospectus describes the general manner in which the selling stockholders identified in this prospectus may offer from time to time in one or more transactions up to 4,128,372 shares of our common stock.

This prospectus only provides you with a general description of the common stock that may be sold in these transactions. If necessary, the specific manner in which the shares of common stock may be offered and sold will be described in a supplement to this prospectus, which supplement may also add, update or change any of the information contained in this prospectus. We may also authorize one or more free writing prospectuses to be provided to you that may contain material information relating to this offering. This prospectus does not contain all of the information included in the registration statement we filed with the SEC. For further information about us or the common stock offered hereby, you should carefully read this prospectus, any applicable prospectus supplement, any related free writing prospectuses, the information and documents incorporated herein by reference and the additional information under the heading “Where You Can Find More Information” before making an investment decision.

You should rely only on the information contained or incorporated by reference in this prospectus, any applicable prospectus supplement and any related free writing prospectuses that we may authorize to be provided to you.

To the extent there are inconsistencies between any prospectus supplement, this prospectus and/or any documents incorporated by reference, the document with the most recent date will control.

PROSPECTUS SUMMARY

Unless otherwise indicated or the context otherwise requires, the terms the “Company,” “ECOR,” “electroCore,” “we,” “us,” “our,” and similar references refer to electroCore, Inc., a Delaware corporation, and its subsidiaries.

Business Overview of electroCore, Inc.

We are a commercial stage medical device company with a proprietary non-invasive vagus nerve stimulation, or nVNS therapy. nVNS is a platform bioelectronic medical therapy that modulates neurotransmitters and immune function through its effects on both the peripheral and central nervous systems. We are initially focused on neurology, and our therapy, gammaCore, is cleared by the U.S. Food and Drug Administration, or FDA, for use by adults for the following four neurology indications: the acute treatment of pain associated with each of migraine and episodic cluster headache, or eCH, the preventive treatment of migraine headache and adjunctive use for the preventive treatment of cluster headaches, or CH. We are also considering the potential for several additional indications for our nVNS technology, which is being studied in a number of investigator-initiated studies.

Our gammaCore treatment is the first FDA-cleared, prescription-only nVNS therapy. Historically, vagus nerve stimulation, or VNS, required an invasive surgical procedure to permanently implant a costly medical device. These limitations prevented VNS from being used, other than for the most severe patients. Our lead product, gammaCore Sapphire, is a proprietary, simple-to-use handheld delivery system intended for multi-year use. Currently, it is prescribed on a monthly or on a 93-day basis and is both rechargeable and reloadable. gammaCore Sapphire permits patients to self-administer doses of nVNS on an as-needed basis for acute treatment, or at regular intervals for prevention therapy.

Non-invasive delivery of VNS by our gammaCore Sapphire is enabled by a proprietary high-frequency burst waveform that safely and comfortably passes through the skin and stimulates therapeutically relevant fibers in the vagus nerve. Multiple published studies suggest that VNS works through the modulation of neurotransmitters and has a measurable effect similar to several classes of commonly prescribed medications.

The FDA cleared our gammaCore therapy for the acute treatment of pain associated with migraine in adults in January 2018, and for preventive treatment of migraine headache in adult patients on March 26, 2020. Migraine is a debilitating primary headache condition that is estimated to affect approximately 12% of the global adult population and disproportionately affects women of child-bearing years. Migraine is estimated to affect 36 million adults in the United States. Some reports suggest that up to 60% of migraine suffers are dissatisfied with or have contraindications to the current standard of care treatments for migraine, such as “triptan” medications. In April 2017, the FDA cleared gammaCore for the acute treatment of pain associated with eCH, and in December 2018, the FDA cleared gammaCore for adjunctive use for the prevention of CH. CH is an extremely painful form of headache affecting approximately 400,000 people in the United States. Prior to gammaCore, injectable sumatriptan was the only FDA-approved, commercially available acute CH treatment, and there was no FDA-approved therapy for the prevention of CH.

The four FDA clearances of our gammaCore therapy were facilitated by the FDA’s creation of a new regulatory category: External Vagus Nerve Stimulator for Headache (21 CFR 882-5892). Based on this category’s description, we anticipate that some additional label expansions may be possible through the pathway under Section 510(k) of the Federal Drug and Cosmetic Act.

In September 2011, we received a CE Certificate of Conformity for gammaCore for the treatment of primary headache from the British Standards Institution, a European Union notified body. This CE Certificate of Conformity allowed us to affix the CE Mark on gammaCore and to commercialize it in the European Economic Area and other countries that recognize the European CE Mark, including the United Kingdom, which is

3

currently our predominant geographic market outside the United States. In addition to the CE Certificate of Conformity for primary headache, between September 2011 and October 2013 we received CE Certificates of Conformity on gammaCore covering four other specific indications for use, including reactive airway disease and gastric motility disorders. In 2019, the National Institute for Health and Care Excellence, or NICE published a Medical Technology Guidance document recommending the use of gammaCore for CH within England’s National Health Service.

RISK FACTORS

Investment in our common stock involves risks. Prior to making a decision about investing in our common stock, you should consider carefully all of the information included in and incorporated by reference or deemed to be incorporated by reference in this prospectus or the applicable prospectus supplement, including the risk factors incorporated by reference herein from our Annual Report on Form 10-K for the year ended December 31, 2019 filed with the SEC on March 30, 2020 and our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020 filed with the SEC on May 15, 2020, as updated by annual, quarterly and other reports and documents we file with the SEC after the date of this prospectus and that are incorporated by reference herein or in any applicable prospectus supplement or any free writing prospectus. Each of these risk factors could have a material adverse effect on our business, results of operations, financial position or cash flows, which may result in the loss of all or part of your investment. The risks and uncertainties we have described are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently consider immaterial may also impair our business operations. If any of these risks actually occur, our business and financial results could be harmed. In that case, the trading price of our common stock or other securities could decline. To the extent a particular offering implicates additional known material risks, we will include a discussion of those risks in the applicable prospectus supplement.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and certain information incorporated herein by reference contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those discussed in the forward-looking statements. The statements contained in this prospectus that are not purely historical are forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act.

These statements are based on the beliefs and assumptions of our management based on information currently available to management. Such forward-looking statements are subject to risks, uncertainties and other important factors that could cause actual results and the timing of certain events to differ materially from future results expressed or implied by such forward-looking statements.

Factors that could cause or contribute to such differences include, but are not limited to, those included in this prospectus and the documents incorporated by reference herein and therein, as well as those contained in our Annual Report on Form 10-K for the year ended December 31, 2019, our Quarterly Report on Form 10-Q for the quarter ended March 31, 2020, and our Current Reports on Form 8-K, including those described under “Risk Factors” herein and therein.

There may be additional risks, uncertainties and factors that we do not currently view as material or that are not known. The forward-looking statements contained in this document are made only as of the date of this document. Except as required by law, we undertake no obligation to update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, as well as those described elsewhere in this prospectus, and other factors that we may publicly disclose from time to time. Furthermore, such forward-looking statements speak only as of the date made.

Each such selling stockholder is an affiliate and/or existing shareholder of the Company, including certain members of our board of directors. An aggregate of 1,564,345 shares of our common stock being registered for resale pursuant to this prospectus were issued to our legal counsel, Dentons US LLP, to satisfy certain outstanding financial obligations owed by the Company. An aggregate of 505,205 shares of our common stock being registered for resale pursuant to this prospectus were acquired by certain selling stockholders pursuant to a Securities Purchase Agreement dated May 18, 2020, at a price of $0.9178 per share.

To our knowledge, other than the relationships described herein, neither the selling stockholders nor their affiliates have any family relationships with our officers, other directors or controlling stockholders.

If any of the selling stockholders is an affiliate of broker-dealers, it and any participating broker-dealers are deemed to be “underwriters” within the meaning of the Securities Act, and any commissions or discounts given to that selling stockholder or broker-dealer may be regarded as underwriting commissions or discounts under the Securities Act.

PLAN OF DISTRIBUTION

We are registering the shares of common stock on behalf of the selling stockholders. The selling stockholders and any of their pledgees, assignees, distributees, and successors-in-interest in our common stock received after the date of this prospectus from the selling stockholders as a partnership distribution, gift, pledge, or other transfer, may, from time to time, sell, transfer, or otherwise dispose of any or all of the common stock covered hereby on the Nasdaq Global Select Market or any other stock exchange, market or trading facility on which the common stock is traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of the sale, at varying prices determined at the time of sale, or at negotiated prices. The selling stockholders may use any one or more of the following methods when selling common stock:

The selling stockholders may also sell common stock under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus.

In connection with the distribution of the shares, the selling stockholders may also enter into hedging transactions with broker-dealers or other financial institutions. In connection such transactions, broker-dealers or other financial institutions may engage in short sales of our common stock in the course of hedging the positions they assume with the selling stockholders. The selling stockholders may also: (i) sell our common stock short and redeliver the registered shares to close out such short positions; (ii) enter into option or other types of transactions that requires any of the selling stockholders to deliver the shares to a broker-dealer, who will then resell or transfer the shares pursuant to this prospectus (as supplemented or amended to reflect such transaction); or (iii) loan or pledge the shares to a broker-dealer who may sell the loaned shares or, in the event of default, sell the pledged shares pursuant to this prospectus (as supplemented or amended to reflect such transaction).

Broker-dealers engaged by the selling stockholders may arrange for other broker-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the selling stockholders (or, if any broker-dealer acts as agent for the purchaser of common stock, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2121; and in the case of a principal transaction a markup or markdown in compliance with FINRA IM-2121.

The selling stockholders and any broker-dealers or agents that are involved in selling the common stock may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the common

10

stock purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act. The selling stockholders have informed us that they do not have any written or oral agreement or understanding, directly or indirectly, with any person to distribute the common stock.

We are required to pay certain fees and expenses incurred by us incident to the registration of the common stock. We will not receive any proceeds from the sale of the shares by the selling stockholders.

We agreed to keep this prospectus effective until the earlier of (i) the date that the common stock may be resold by the selling stockholders without registration and without regard to any volume or manner-of-sale limitations by reason of Rule 144, without the requirement for us to be in compliance with the current public information under Rule 144 under the Securities Act or any other rule of similar effect or (ii) the date that all of the common stock has been sold pursuant to this prospectus or Rule 144 under the Securities Act or any other rule of similar effect. The resale common stock will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the resale common stock covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale common stock may not simultaneously engage in market making activities with respect to the common stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the common stock by the selling stockholders or any other person. We will make copies of this prospectus available to the selling stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

11

As of the date of this prospectus, Dentons US LLP beneficially owns an aggregate of 1,564,345 shares of our common stock.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

The following table sets forth all costs and expenses payable by us in connection with the sale of the common stock being registered hereunder. All of the amounts shown shall be paid by us and are estimates except for the SEC registration fee.

As permitted by Section 102 of the Delaware General Corporation Law, our certificate of incorporation and bylaws contain provisions that limit or eliminate the personal liability of our directors for a breach of their fiduciary duty of care as directors. The duty of care generally requires that, when acting on behalf of the corporation, directors exercise an informed business judgment based on all material information reasonably available to them. Consequently, a director will not be personally liable to us or our stockholders for monetary damages for breach of fiduciary duty as a director, except for liability for:

These limitations of liability do not affect the availability of equitable remedies such as injunctive relief or rescission. Our certificate of incorporation also authorizes us to indemnify our officers, directors and other agents to the fullest extent permitted under Delaware law.

As permitted by Section 145 of the Delaware General Corporation Law, our bylaws provide, among other things, that:

II-1

Our certificate of incorporation and our bylaws provide for the indemnification provisions described above and elsewhere herein. We have entered into separate indemnification agreements with our directors and officers which are broader than the specific indemnification provisions contained in the Delaware General Corporation Law. These indemnification agreements generally require us, among other things, to indemnify our officers and directors against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct. These indemnification agreements also generally require us to advance any expenses incurred by the directors or officers as a result of any proceeding against them as to which they could be indemnified. In addition, we have purchased a policy of directors’ and officers’ liability insurance that insures our directors and officers against the cost of defense, settlement or payment of a judgment in some circumstances. These indemnification provisions and the indemnification agreements may be sufficiently broad to permit indemnification of our officers and directors for liabilities, including reimbursement of expenses incurred, arising under the Securities Act of 1933, as amended, or the Securities Act.

Insofar as indemnification for liabilities arising under the Securities Act, may be permitted to our directors, officers and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable.

See the Exhibit Index attached to this registration statement and incorporated herein by this reference.

(a) The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or any decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

Provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is a part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

II-2

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrants pursuant to the foregoing provisions described in Item 15, or otherwise, the registrants have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrants of expenses incurred or paid by a director, officer or controlling person of any registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, each appropriate registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Re: Registration Statement on Form S-3

Ladies and Gentlemen:

We have acted as counsel to electroCore, Inc., a Delaware corporation (the “Company”), in connection with a registration statement on Form S-3 (the “Registration Statement”), being filed by the Company with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Act”), for registration of the resale of 4,128,372 shares of the Company’s common stock, $0.001 par value per share (the “Shares”), such Shares to be offered and sold from time to time by the selling stockholders listed in the Registration Statement under the heading “Selling Stockholders.”

This opinion is being delivered to you pursuant to Item 601(b)(5) of Regulation S-K under the Act at the request of the Company.

In connection with rendering this opinion, we have examined originals, certified copies or copies otherwise identified as being true copies of the following: (i) the Company’s Certificate of Incorporation, (ii) the Company’s By-Laws, (iii) the Registration Statement, (iv) corporate proceedings of the Company relating to the Shares, and (v) such other instruments and documents as we have deemed necessary under the circumstances.

We have assumed the genuineness and authenticity of all documents examined by us and all signatures thereon, and the conformity to originals of all copies of documents examined by us.

Based upon the foregoing, and in reliance thereon, and subject to the qualifications, limitations and exceptions stated herein, we are of the opinion having due regard for such legal considerations as we deemed relevant, that the Shares have been validly issued, fully paid and are nonassessable.

Our opinions are subject to the effect of federal and state bankruptcy, insolvency, reorganization, arrangement, moratorium, fraudulent conveyance and other laws relating to or affecting the rights of secured or unsecured creditors generally (or affecting the rights of only creditors of specific types of debtors), with respect to which we express no opinion.

Our opinions are subject to limitations imposed by general principles of equity or public policy upon the enforceability of any of the remedies or covenants, including, without limitation, concepts of materiality, good faith and fair dealing and upon the availability of injunctive relief or other equitable remedies, and the application of principles of equity (regardless of whether enforcement is considered in proceedings at law or in equity).

We express no opinion as to the laws of any jurisdiction other than Delaware general corporation law and the federal laws of the United States of America.

We hereby consent to the inclusion of this opinion as Exhibit 5.1 to the Registration Statement and to the references to our firm under the caption “Legal Matters” in the Registration Statement. In giving our consent, we do not admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations thereunder.

Exhibit 23.1

Consent of Independent Registered Public Accounting Firm

The Board of Directors

electroCore Inc.:

We consent to the use of our report incorporated herein by reference and to the reference to our firm under the heading “Experts” in the prospectus.

Our report dated March 30, 2020 contains an explanatory paragraph that states that the Company has suffered recurring losses from operations and has a net capital deficiency, which raise substantial doubt about its ability to continue as a going concern. The consolidated financial statements do not include any adjustments that might result from the outcome of that uncertainty.
