Upon their respective issue, a Series Z Warrant enabled the holder to immediately purchase one share of PAVM common stock at an exercise price of $1.60 per share, effective June 1, 2018. The Series Z Warrant exercise price was initially $3.00 per share through May 31, 2018, and then $1.60 per share effective June 1, 2018, wherein, on May 15, 2018, the Company’s board of directors approved a reduction to the Series Z Warrant exercise price to $1.60 per share, effective June 1, 2018, upon completion of the period-of-notice to the then-current Series Z Warrant holders. See herein below for further information with respect to the modification expense recognized in connection with the Series Z Warrant exercise price adjustment. The Series Z Warrant $1.60 exercise price is not subject-to further adjustment, unless by action of the PAVmed Inc board of directors, or the effect of stock dividends, stock splits or similar events affecting the common stock. Under no circumstances will the Company be required to net cash settle the Series Z Warrants, nor to pay any liquidated damages in lieu of delivery of shares of common stock of the Company resulting from a failure to satisfy any obligations under the Series Z Warrant, and, the Series Z Warrants expire after the close of business on April 30, 2024, if not earlier redeemed by the Company, as discussed below. Commencing on May 1, 2019, the Company may redeem the outstanding Series Z Warrants, at the Company’s option, in whole or in part, at a price of $0.01 per Series Z Warrant at any time while the Series Z Warrants are exercisable, upon a minimum of 30 days’ prior written notice of redemption, if, and only if, the volume weighted average closing price of the Common Stock equals or exceeds $9.00 (subject to adjustment) for any 20 out of 30 consecutive trading days ending three business days before the Company issues its notice of redemption, and provided the average daily trading volume in the Common Stock during such 30-day period is at least 20,000 shares per day; and if, and only if, there is a current registration statement in effect with respect to the shares of Common Stock underlying such Series Z Warrants. As noted above, a total of 5,075,849 Series Z Warrants were issued-upon-exchange of 10,151,682 Series W Warrants, in an exchange offer transaction referred to as the “Series W Warrants Exchange Offer” and the “April 5, 2018 Exchange Date”. In this regard, pursuant to an offer-to-exchange letter dated February 20, 2018, as included in a Tender Offer Statement on Schedule TO filed with the SEC on February 20, 2018, wherein, the Company offered to issue one Series Z Warrant in exchange for two Series W Warrants. Such Series W Warrants Exchange Offer commenced on February 20, 2018 and had April 2, 2018 expiration date. The Series W Warrants Offer-to-Exchange was completed after expiration of the guaranteed delivery period on April 5, 2018. The Series Z Warrants issued-upon-exchange of the Series W Warrants on the April 5, 2018 Exchange Date, upon their issuance, enabled the holder to immediately purchase one share of PAVM common stock at an exercise price of $1.60 per share, effective June 1, 2018, with an expiry of April 30, 2024. The Series Z Warrant exercise price was initially $3.00 per share through May 31, 2018, and then $1.60 per share effective June 1, 2018. See herein below for further information with respect to the Series Z Warrant exercise price adjustment and the resulting modification expense recognized on June 1, 2018. The Series Z Warrant $1.60 exercise price is not subject-to further adjustment, unless by action of the PAVmed Inc board of directors, or the effect of stock dividends, stock splits or similar events affecting the common stock. The Series Z Warrants are redeemable by the Company under certain conditions, as discussed above. On the April 5, 2018 Exchange Date, the Series W Warrants Exchange Offer resulted in the recognition of a modification expense under the analogous guidance of FASB ASC Topic 718, Stock-Based Compensation Fair Value Assumptions Series Z Series W April 5, 2018 Exchange Date Warrants Warrants Calculated aggregate estimated fair value $ 3,304,377 $ 2,537,921 Series Z Warrants issued /Series W Warrants extinguished 5,075,849 10,151,682 Value of common stock $ 1.66 $ 1.66 Exercise price per share $ 3.00 $ 5.00 Expected term (years) 2.7 3.8 Volatility 55 % 55 % Risk free rate 2.7 % 2.5 % Dividend yield 0 % 0 % As noted above, the Series Z Warrant exercise price was initially $3.00 per share through May 31, 2018, and then $1.60 per share effective June 1, 2018, wherein, on May 15, 2018, the Company’s board of directors approved a reduction to the Series Z Warrant exercise price to $1.60 per share, effective June 1, 2018, upon completion of the period-of-notice to the then-current Series Z Warrant holders. The Series Z Warrant exercise price adjustment resulted in the recognition of a modification expense under the analogous guidance of FASB ASC 718 with respect to stock option modification, as described herein above with respect to the Series W Warrant Exchange Offer. In this regard, on the June 1, 2018 effective date of the Series Z Warrant adjusted exercise price, a modification expense of $1,140,995 was recognized, with a corresponding increase to addition paid-in capital. Such incremental fair value was estimated using a Black-Scholes valuation model, using the following assumptions: Immediately Immediately Fair Value Assumptions - June 1, 2018 After Before Series Z Warrant Exercise Price Adjustment Modification Modification Calculated aggregate estimated fair value $ 3,477,692 $ 2,336,697 Series Z Warrants - issued and outstanding - June 1, 2018 7,815,039 7,815,039 Value of common stock per share $ 1.00 $ 1.00 Exercise price per share - Series Z Warrant $ 1.60 $ 3.00 Expected term - years 5.9 5.9 Volatility 58 % 58 % Risk free interest rate 2.8 % 2.8 % Dividend yield 0 % 0 % Additionally, the Series Z Warrants issued in both the Series A and Series A-1 Exchange Offer (March 15, 2018) and the Series W Warrants Exchange Offer (April 5, 2018), each as discussed herein above, were issued under the (original) “Series Z Warrant Agreement”. The Company’s board of directors approved Amendment No. 1 to such original Series Z Warrant Agreement, resulting in the “Amended and Restated Series Z Warrant Agreement”, dated June 8, 2018, referred to as the Amended Series Z Warrant Agreement. The principal provisions of such Amendment No. 1, include among other items: to provide for a “late delivery fee” for shares issued outside of the “standard delivery period”, including delivery of shares upon Series Z Warrant exercise for open market or other purchase transactions - i.e. “buy-in fee”, with each such payment, if any, in addition to and not in lieu of delivery of shares, and, to provide for a standard provision (“plain vanilla”) in the event the Company engages in a “Fundamental Transaction”, as defined, wherein the Series Z Warrant may participate pari passu with common stockholders in the consideration paid by an acquiror for the Company’s shares, with such payment, if any, made by the acquiring entity and not paid by the Company as issuer. The Series Z Warrant Agreement No. 1, was evaluated under the analogous guidance of FASB ASC 718 with respect to stock option modification, as discussed above, but did not result in the recognition of a modification expense as there was no incremental increase in the estimated fair value as described above. Series W Warrants There were 381,818 and 10,567,845 Series W Warrants issued and outstanding as of June 30, 2018 and December 31, 2017, respectively. The Series W Warrants have an exercise price of $5.00 per share, with such exercise price not subject to further adjustment, except in the event of stock dividends, stock splits or similar events affecting the common stock, and became exercisable on October 28, 2016 and expire on January 29, 2022, or earlier upon redemption by the Company, as discussed below. Under no circumstances will the Company be required to net cash settle the Series W Warrants, nor to pay any liquidated damages resulting from a failure to satisfy any obligations under the Series W Warrant. Previously, a total of 1,060,000 Series W Warrants were issued on the April 28, 2016 closing date of the Company’s IPO, and on the same April 28, 2016 IPO closing date, there were 9,560,295 remaining unexercised warrants previously issued in private placements before the IPO, with such warrants automatically converted into identical Series W Warrants issued in the IPO, and are therefore aggregated with the Series W Warrants issued in the IPO, and together are collectively referred to as “Series W Warrants”. As noted above, on the April 5, 2018 Exchange Date of the Series W Warrant Exchange Offer, a total of 10,151,682 Series W Warrants were extinguished upon being exchanged for the issue of a total of 5,075,849 Series Z Warrants. On January 11, 2018, the Company filed with the SEC a Tender Offer Statement on Schedule TO offering Series W Warrants holders a temporary exercise price of $2.00 per share, with such offer having an expiry of February 8, 2018 (“Series W Warrants Offer-to-Exercise”). As of the February 8, 2018 expiry date, a total of 34,345 Series W Warrants were exercised at the temporary exercise of $2.00 per share, resulting in $68,690 of cash proceeds, before offering costs of $50,520. In March 2017 and September 2017, 400 and 11,850 Series W Warrants were exercised for cash proceeds of $2,000 and $59,250, respectively, resulting in the issuances of a corresponding number of shares of common stock of the Company. Commencing April 28, 2017, the Company may redeem the outstanding Series W Warrants (other than those outstanding prior to the IPO held by the Company’s management, founders, and members thereof, but including the warrants held by the initial investors), at the Company’s option, in whole or in part, at a price of $0.01 per warrant: at any time while the warrants are exercisable; upon a minimum of 30 days’ prior written notice of redemption; if, and only if, the volume weighted average price of the Company’s common stock equals or exceeds $10.00 (subject-to adjustment) for any 20 consecutive trading days ending three business days before the Company issues its notice of redemption, and provided the average daily trading volume in the stock is at least 20,000 shares per day; and, if, and only if, there is a current registration statement in effect with respect to the shares of common stock underlying such warrants. The right to exercise will be forfeited unless the IPO Warrants are exercised prior to the date specified in the notice of redemption. On and after the redemption date, a record holder of an IPO Warrant will have no further rights except to receive the redemption price for such holder’s IPO Warrant upon surrender of such warrant. Series S Warrants Previously, under the Note and Security Purchase Agreement with Scopia, the Company issued 2,660,000 Series S Warrants to Scopia and its designees, which were immediately exercisable upon issuance and each may be exercised for one share of common stock of the Company at an exercise price of $0.01 per share, with such exercise price not subject to further adjustment, except for the effect of stock dividends, stock splits or similar events affecting the common stock, and may be exercised for cash or on a cashless basis. Under no circumstances will the Company be required to net cash settle the Series S Warrants, nor to pay any liquidated damages resulting from a failure to satisfy any obligations under the Series S Warrant. Any Series S Warrants outstanding on the June 30, 2032 expiration date will be automatically exercised on a cashless basis. There were 1,199,383 and 1,473,640 Series S Warrants issued and outstanding as of June 30, 2018 and December 31, 2017, respectively. In March 2018, a total of 274,257 Series S Warrants exercised for $2,743 of cash proceeds, resulting in the issue of a corresponding number of a shares of common stock of the Company. In each of October 2017 and November 2017, 532,000 (or a total of 1,064,000) Series S Warrants were exercised for total cash proceeds of $10,640, resulting in the issuance of a corresponding number of shares of common stock of the Company, and in November 2017, a total of 122,360 Series S Warrants were exercised on a cashless basis, resulting in the issuance of a total of 122,080 shares of common stock of the Company. The Senior Secured Note and the Series S Warrants are freestanding financial instruments, as the Series S Warrants were immediately legally detachable from the Senior Secured Note and were immediately exercisable. The Series-S Warrants are classified as equity in the unaudited condensed consolidated balance sheet. The Senior Secured Note net cash proceeds were allocated to the Senior Secured Note and the Series S Warrants based on their respective relative fair value, resulting in an allocation of $1,408,125 to the Senior Secured Note and $3,434,452 to the Series S-Warrants. See Note 12, Note and Securities Purchase Agreement, Senior Secured Note, and Series S Warrants The Company filed a registration statement on Form S-3 (File No. 333-221406), declared effective January 8, 2018, to register the issuance of a total of 2,810,654 shares of common stock of the Company, including 1,473,640 shares issuable, and 1,186,080 shares previously issued, upon the exercise of Series S Warrants; and, the registration of (i) the issuance of 150,934 shares of the Company’s common stock upon the exercise of 150,934 certain Series W Warrants issued prior to the Company’s IPO, but only in the event such certain Series W Warrants are publicly transferred pursuant to Rule 144 prior to their exercise, or (ii) the resale of such 150,934 shares of common stock, but only in the event such certain Series W Warrants are exercised prior to being publicly transferred pursuant to Rule 144. Series A-1 Warrants As of June 30, 2018 and December 31, 2017, there were zero and 279,837 Series A-1 Warrants issued and outstanding, respectively. Previously, 125,000 Series A-1 Warrants were issued on August 4, 2017 in the “Series A-1 Preferred Stock Units private placement”, as discussed herein above. The November 17, 2017 Series A Exchange Offer, as discussed herein above, resulted in 154,837 Series A-1 Warrants issued upon exchange of 154,837 Series A Warrants. Accordingly, as of December 31, 2017, 279,837 Series A-1 Warrants were issued and outstanding. The March 15, 2018 Series A and Series A-1 Exchange Offer, as discussed herein above, resulted in 279,837 Series A-1 Warrants exchanged for the issue of 1,399,185 Series Z Warrants. Accordingly, as of the March 15, 2018 Exchange Date of the Series A and Series A-1 Exchange Offer, there we no Series A-1 Warrants issued and outstanding. See herein above for further information regarding the Series Z Warrant. See Note 11, Financial Instruments Fair Value Measurements The Series A-1 Warrants were immediately exercisable upon issuance and expire after the close of business on April 30, 2024, and each may be exercised for one share of common stock of the Company at an exercise price of $6.67 per share, with such exercise price not subject to further adjustment, except for the effect of stock dividends, stock splits or similar events affecting the common stock. Additionally, through April 30, 2024, each Series A-1 Warrant, at the option of the holder, may be exchanged into either five Series W Warrants of four Series X-1 Warrants. The Series W Warrants or Series X-1 Warrants issued upon the exchange of a Series A-1 Warrant are discussed below. No Series A-1 Warrants had been exchanged for Series W Warrants nor Series X-1 Warrants as of the Series A and Series A-1 Exchange Offer March 15, 2018 Exchange Date and December 31, 2017. The Series A-1 Warrants were not subject to redemption, and under no circumstances will the Company be required to net cash settle the Series A-1 Warrants. The Series A-1 Warrants have been accounted for as equity-classified warrants, with an issue-date allocated fair value of $310,450, as discussed above. During the time the Series A-1 Warrants are outstanding, the holders will be entitled to participate in dividends or other distributions on a pro rata basis based upon the equivalent number of common shares that would have been outstanding had the warrants been fully exercised. As noted above, the Series A-1 Amendment No.1 provided for a Series A-1 Warrant to be exchanged for four Series X-1 Warrants, or additionally, exchanged for five Series W Warrants. The Series X-1 Warrants replaced the previous election to exchange one Series A-1 Warrant for four Series X Warrants. Notwithstanding, the Series X-1 Warrants are substantively equivalent to the Series X Warrants with respect to material contractual terms and conditions, including the same $6.00 per share exercise price, and dates of exercisability and expiry. The Series A-1 Amendment No.1 modification to the Series A-1 Warrants’ exchange elections was accounted for under the analogous guidance of FASB ASC 718, wherein, the incremental fair value is measured as the difference between the fair value immediately after the modification as compared to the fair value immediately before the modification, with such incremental fair value, to the extent an increase, recognized as a modification expense. On the October 18, 2017 date of the Series A-1 Amendment No.1 the Company recognized a current period expense related to the Series A-1 Warrants’ modification of $222,000, with such expense included in other income (expense) in the unaudited condensed consolidated statement of operations, with a corresponding increase in additional paid-in capital in the unaudited condensed consolidated balance sheet, as the Series A-1 Warrants are equity classified. Such incremental fair value was estimated using a Black-Scholes valuation model, assuming the exchange of one Series A-1 Warrant for five Series W Warrants after the Series A-1 Warrant modification, as compared to an exchange of one Series A-1 Warrant for four Series X Warrants before such modification, using the following assumptions: Series A-1 Amendment No. 1 Series A-1 Warrants Modification Fair Value - October 18, 2017 Immediately Immediately Fair Value Assumptions - October 18, 2017 After Before Series A-1 Warrant Agreement - Amendment No. 1 Modification Modification Calculated aggregate estimated fair value $ 1,531,000 $ 1,309,000 Series A-1 Warrants - issued and outstanding - October 18, 2017 125,000 125,000 Value of common stock per share $ 5.40 $ 5.40 Exercise price per share - Series W Warrant $ 5.00 $ — Exercise price per share - Series X Warrant $ — $ 6.00 Expected term - years 4.3 6.5 Volatility 55 % 52 % Risk free interest rate 1.9 % 2.1 % Dividend yield 0 % 0 % Series A Warrants As of June 30, 2018 and December 31, 2017, there were zero and 268,001 Series A Warrants issued and outstanding, respectively. Previously, a total of 422,838 Series A Warrants were issued in the Series A Preferred Stock private placement, as discussed herein above. The November 17, 2017 Series A Exchange Offer, as discussed herein above, resulted in 154,837 Series A Warrants exchanged for the issue of 154,837 Series A-1 Warrants. Accordingly, as of December 31, 2017, 268,001 Series A Warrants were issued and outstanding. The March 15, 2018 Series A and Series A-1 Exchange Offer, as discussed herein above, resulted in 268,001 Series A Warrants exchanged for the issue of 1,340,005 Series Z Warrants. Accordingly, as of the March 15, 2018 Exchange Date of the Series A and Series A-1 Exchange Offer, there were no Series A Warrants issued and outstanding. See herein above for further information regarding the Series Z Warrant. See Note 11, Financial Instruments Fair Value Measurements The Series A Warrants may be exercised for one share of common stock at an exercise price of $6.61 per share. Previously, upon issuance, the Series A Warrant exercise was initially $8.00 per share. In this regard, the Series A Warrant exercise price was subject to further reduction by a prescribed formula on a weighted average basis in the event the Company issues common stock, options, or convertible securities at a price lower than the exercise price of Series A Warrants immediately prior to such securities issuance. Additionally, through April 30, 2024, each Series A Warrant, at the election of the holder, may be exchanged for four Series X Warrants, with such warrants exercisable for one share of common stock at $6.00 per share, with such exercise price not subject to further adjustment, except in the event of stock dividends, stock splits or similar events affecting the common stock. The Series X Warrants were exercisable commencing on the first trading day following October 31, 2018 and would have expired April 30, 2024. As noted above, the Series A Warrants are accounted for as a derivative liability under FASB ASC 815, as, along with other provisions, the conversion price is subject to potential adjustment resulting from future financing transactions, under certain conditions. The Series A Warrant was classified as a current liability in the unaudited condensed consolidated balance sheet, initially measured at its issue-date fair value, with such fair value subsequently remeasured at each reporting period, with the resulting fair value adjustment recognized as other income or expense in the unaudited condensed consolidated statement of operations. See Note 11, Financial Instruments Fair Value Measurements Unit Purchase Options In connection with the IPO, on April 28, 2016 53,000 unit purchase options (“UPO”) were issued to the IPO selling agents. The holders of the UPO may purchase a unit identical to the unit issued in the Company’s IPO, as discussed above, at an exercise price of $5.50 per unit. The UPO was recognized as an offering cost of the Company’s IPO, with an estimated the fair value of $105,100, determined using a Black-Scholes option pricing model with the following assumptions: fair value of the underlying unit of $5.00, expected volatility of 50%, risk free rate of 1.28%, remaining contractual term of 4.6 years, and a dividend yield of 0%. |
