Interstate Battery Agreements

Investment Agreement

The Company entered into a Credit Agreement dated May 18, 2016 with Interstate Battery pursuant to which Interstate Battery loaned the Company $5,000,000 in consideration of the Company’s issuance of a secured convertible promissory note in the original principal amount of $5,000,000. The note bears interest at the rate of eleven percent (11%) per annum, compounding monthly, and all interest is payable upon the earlier of maturity or conversion of the principal amount. The loan matures on May 24, 2019. The outstanding principal is convertible into shares of the Company’s common stock at a conversion price of $7.12 per share. The Company’s obligations under the note and Credit Agreement are secured by a second priority lien on the real estate, fixtures and equipment at the Company’s recycling facility at McCarran, Nevada. The Credit Agreement includes representations, warranties, and affirmative and negative covenants that are customary of institutional credit agreements.

Pursuant to the Credit Agreement, the Company also issued to Interstate Battery two common stock purchase warrants, including:

The warrants contain cashless exercise and standard anti-dilution adjustment provisions. If Interstate converts its convertible note and exercises both warrants in their entirety, it will own slightly less than 20% of the Company’s common stock at an average price per share of approximately $7.93.

The Company also entered into a Stock Purchase Agreement dated May 18, 2016 with Interstate Battery pursuant to which the Company issued and sold to Interstate Battery 702,247 shares of the Company’s common stock at $7.12 per share for gross proceeds of approximately $5,000,000. The Stock Purchase Agreement includes customary representations, warranties, and covenants by Interstate Battery and us, and an indemnity from us in favor of Interstate Battery.

In connection with the investment transactions, the Company also entered into an Investors Rights Agreement dated May 18, 2016 with Interstate Battery pursuant to which the Company granted Interstate Battery customary demand and piggyback registration rights, limited board observation rights over the next three years and limited preemptive rights allowing Interstate Battery the right to purchase its proportional share of certain future equity issuances by the Company over the next three years. The Company included all of the Interstate Battery shares in its S-3 Registration Statement filed with the Securities and Exchange Commission on August 1, 2016.

The investment transactions with Interstate Battery closed on May 24, 2016. There were no sales commissions paid by the Company in connection with its sale of securities to Interstate Battery.

The Company allocated the $10.0 million proceeds from the Credit Agreement and Stock Purchase Agreement, to the various securities based on their relative fair values on the closing date of May 24, 2016.

The fair value of the warrants using the Black-Scholes-Merton Option Pricing Model and the assumptions are listed in the table below (FV of warrant in thousands).

Both warrants were issued on May 24, 2016, when the closing market price of our stock was $11.39.

The table below presents the allocation of the proceeds based on the relative fair values of the stock, warrants and note (in thousands).

The difference between the face value of the convertible note and the allocated amount (which considers both the allocated fair value of the issued stock and allocated fair value of the warrants) was recorded as an initial discount to the convertible note; common stock was recorded at its allocated fair value as a credit to par value and additional paid-in capital as appropriate, based on the number of shares issued, and the allocated fair value of the warrant was credited to additional paid-in capital. After taking into consideration the amortization of the note discount, the effective interest rate on the convertible note is 184.75%.

The convertible note includes an embedded BCF. The intrinsic value of the BCF was treated as an additional component of the discount attributable to the convertible note. The initial discount (attributable to the stock and warrants as noted above) and the discount attributable to the BCF exceeds the face amount of the convertible note. To avoid reducing the initial net carrying value of the convertible note to or below zero, the discount attributable to the BCF was limited such that the aggregate of all discounts does not exceed 99.5% of the face amount of the convertible note. The discount is being accreted to interest expense using the effective interest method over the three-year life of the loan. If the loan is converted prior to its maturity, any remaining discount will be expensed immediately.

Costs incurred in connection with the deal of $771,000 were allocated between additional paid-in capital and prepaid financing/ debt discount (“debt issuance costs”) in the same manner as the above allocation of proceeds. The allocated debt issuance costs of $142,000 were recorded as a reduction to the carrying amount of the convertible note and are being amortized as interest expense within the condensed consolidated statements of operations over the three-year life of the loan. The remaining $629,000 was recorded as a reduction to additional paid-in capital.

National Securities Placement

On May 18, 2016, the Company entered into a Stock Purchase Agreement and a Registration Rights Agreement with certain accredited investors pursuant to which the Company issued and sold to the investors 719,333 shares of its common stock at a price of $7.12 per share for the gross proceeds of approximately $5,122,000. The Stock Purchase Agreement includes customary representations, warranties, and covenants by the investors and the Company, and an indemnity from the Company in favor of the investors. The private placement closed on May 24, 2016. The Company included all of these shares in its S-3 Registration Statement filed with the Securities and Exchange Commission on August 1, 2016. 

National Securities Corporation acted as placement agent for the private placement and received sales commission in the amount of six percent (6%) of the gross proceeds, or a total of $307,000 in commissions from us. In addition, we reimbursed National Securities for its out-of-pocket expenses and legal fees in the aggregate amount of $38,000. The total costs of $345,000 have been recorded as a reduction to additional paid-in capital.

Public Offering

On November 21, 2016, the Company completed a public offering of 2.3 million shares of its common stock at a public offering price of $10.00 per share. Net proceeds to the Company from the public offering were approximately $21.5 million after deducting underwriting discounts, commissions and offering expenses. In connection with the public offering, the underwriter received a fee of $1.4 million and a warrant to purchase 33,450 shares of the Company’s common stock at $10.00 per share that is exercisable commencing May 20, 2017 and expires on November 21, 2019. The fair value of the warrant, $229,000, was recorded as an increase to offering expenses and an increase to additional paid-in capital. The Company calculated the fair value of the warrant using a BlackScholes Merton model with the assumptions as follows: $12.66 closing market value on the date of grant; 3-year term; 72% volatility; 1.36 discount rate and 0% annual dividend rate.

Warrants issued

On September 8, 2014, the Company entered into a consulting agreement with Liquid Patent Consulting, LLC ("LPC"), pursuant to which LPC agreed to provide management, strategic and intellectual property advisory services. The Consulting Agreement had an initial term of 180 days after which it will continue in effect until it is terminated by either party with 30 days written notice to the other party.

As consideration for services provided under the Consulting Agreement the Company issued warrants ("Consulting Warrants") to LPC for the purchase of an aggregate of 436,364 shares of the Company's common stock. LPC subsequently transferred a portion of the Consulting Warrants to a third party. The Consulting Warrants vested upon issue, have a term of three years, an exercise price of $0.0034375 per share and are immediately exercisable, provided that upon the Company's consummation of an IPO, the Consulting Warrants may not be exercised until 90 days after the consummation of the IPO. The Consulting Warrants may be exercised on a cashless basis. As described in Note 17 – Subsequent Events, warrants totaling an aggregate of 392,728 shares were exercised on February 10, 2017 via a cashless exercise resulting in the issuance of 392,605 shares of the Company’s common stock.

In connection with underwriting the IPO, the Company issued on August 5, 2015 to NSC warrants (“IPO Warrants”) to purchase 660,000 shares of the Company’s common stock at an exercise price of $6.00 per share. The IPO Warrants were fully vested upon issuance, are not exercisable until July 30, 2016 and have a term of five years. The registration statement with the Securities and Exchange Commission included an over-allotment of shares available for sale in addition to the IPO. On August 13, 2015, the Company issued warrants to NSC (“O-A Warrants”) to purchase 64,193 shares of the Company’s common stock at an exercise price of $6.00 per share for underwriting the over-allotment sale of shares. The O-A Warrants were fully vested upon issuance, are not exercisable until July 30, 2016 and have a term of five years. The fair values were recorded as an increase to IPO costs and or increase to additional paid in capital. As described in Note 16 – Subsequent Events, warrants totaling an aggregate of 72,420 shares were exercised on February 13, 2017 via a cashless exercise resulting in the issuance of 39,154 shares of the Company’s common stock. An additional 65,177 of these warrants were exercised on February 15, 2017 via a cashless exercise resulting in the issuance of 41,856 shares of the Company’s common stock.

On October 31, 2015, the Company issued warrants to a consultant to purchase 12,500 shares of the Company’s common stock at an exercise price of $6.00 per share. The warrants were fully vested on issuance and expire on July 30, 2018. The fair value of the warrants, calculated by the Black-Scholes-Merton method, $28,000 was recorded to business development and management costs and additional paid in capital in 2015. As described in Note 16 – Subsequent Events, warrants totaling an aggregate of 12,500 shares were exercised on February 16, 2017 via a cashless exercise resulting in the issuance of 8,025 shares of the Company’s common stock.

On November 2, 2015, the Company issued warrants to a consultant to purchase 30,000 shares of the Company’s common stock at an exercise price of $6.00. The warrants were fully vested upon issuance and have a term of one year. The fair value of the warrants, calculated by the Black-Scholes-Merton method, $36,000 was recorded to business development and management costs and additional paid in capital in 2015. As noted below in the “warrants exercised” section, all of these warrants were exercised in June 2017.

Provided below are the principal assumptions used in the measurement of the fair values of the warrants issued during 2015 (Warrants fair value in thousands).

Warrants to purchase 12,500 of the Company’s common stock were issued on January 31, 2016, April 30, 2016 and July 31, 2016, all with an exercise price of $6.00 per share. The warrants were fully vested upon issuance and expire, if not exercised, on July 31, 2018. As described in Note 16 – Subsequent Events, warrants totaling an aggregate of 22,500 shares were exercised on February 16, 2017 via a cashless exercise resulting in the issuance of 14,445 shares of the Company’s common stock.

The following assumptions were used in the Black-Scholes-Merton pricing model to estimate the fair value of the warrant (FV of warrant in thousands).

The fair value of each of the warrants was recorded as increase to business development and management costs and increase in additional paid in-capital.

As noted in the preceding section, warrants to purchase 2,305,378 and 33,450 shares of the Company’s common stock were also issued for the Interstate Battery deal and the November 2016 Public Offering, respectively, during 2016. Please refer to the above section for specific valuation assumptions for these warrants.

Warrants exercised

On June 7, 2016, when the five-day average of closing prices for the Company’s common stock was $12.16 per share, 15,203 shares of the Company’s common stock were issued pursuant to a cashless exercise of a warrant for 30,000 shares of the Company’s common stock with an exercise price of $6.00 per share.

Stock based compensation

In 2014, the Board of Directors adopted the Company's stock incentive plan (the "2014 Plan") under which a maximum of 1,363,637 shares of common stock were authorized for issuance. The 2014 Plan provides for the following types of stock-based awards: incentive stock options; non-statutory stock options; restricted stock; and performance stock. The 2014 Plan, under which equity incentives may be granted to employees and directors under incentive and non-statutory agreements, requires that the option price may not be less than the fair value of the stock at the date the option is granted. Option awards are exercisable until their expiration, which may not exceed 10 years from the grant date.

The stock-based compensation expense recorded was allocated as follows (in thousands):

The following assumptions were used in the Black-Scholes-Merton option pricing model to estimate the fair value of the awards granted during the year ended December 31, 2016 and 2015.

The risk-free interest rate assumption was based on the United States Treasury’s zero-coupon bonds with maturities similar to those of the expected term of the award being valued. The assumed dividend yield was based on the Company’s expectation of not paying dividends in the foreseeable future. The weighted-average expected life of the options was calculated using the simplified method as prescribed by the Securities and Exchange Commission (“SEC”) Staff Accounting Bulletin No. 107 and No. 110) “SAB No. 107 and 110”). This decision was based on the lack of relevant historical data due to the Company’s limited historical experience. In addition, due to the Company’s limited historical data, the estimated volatility also reflects the application of SAB No. 107 and 110, using the weighted average of the Company’s historical volatility and the historical volatility of several unrelated public companies within the recycling industry.

The following table summarizes the stock option activity and related information through December 31, 2016.

The weighted-average grant-date fair value of options granted during the year ended December 31, 2016 was $4.47 per share. The intrinsic value of options exercised during the year ended December 31, 2016 was $22,000. There were no stock option exercises during the year ended December 31, 2015. The amount of cash received from exercise of stock options during the year ended December 31, 2016 was $19,000.

Additional information related to the status of options at December 31, 2016 is as follows:

The intrinsic value of options is the fair value of the Company’s stock at December 31, 2016 less the per share exercise price of the option multiplied by the number of shares.

As of December 31, 2016, there is approximately $1.1 million of total unrecognized compensation cost related to the unvested share-based compensation arrangements granted under the 2014 Plan. The remaining unrecognized compensation cost will be recognized over a weighted-average period of 2.0 years.

The following table summarizes information about stock options outstanding as of December 31, 2016:

Option modification

During the three months ended June 30, 2016, the Compensation Committee of the Board of Directors approved the modification of the terms of a stock option previously granted to a member of its Board of Directors to accelerate vesting and the waiver of the early termination of the option based upon the director’s end of service to the Company. The modification resulted in additional compensation expense of $175,000.
