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 $5.0 million in consideration of the Company’s issuance of a secured convertible promissory note in the original principal amount of $5.0 million. The note bore interest at the rate of eleven percent (11%) per annum, compounding monthly, and all interest was payable upon the earlier of maturity or conversion of the principal amount. The loan was to mature on May 24, 2019. The outstanding principal was 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 were 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 included representations, warranties, and affirmative and negative covenants that are customary of institutional credit agreements. Interstate Battery had previously raised a claim that the Company was in technical breach of a negative covenant under loan. The claimed breach related to the Company’s failure to obtain Interstate Battery’s prior written consent to the Company’s acquisition of Ebonex IPR, Ltd. The Company estimated in 2017 that resolving the claim would result in a charge of $0.6 million. The Company recorded the $0.6 million in general and administrative expenses as of December 31, 2017 with the offset in accrued liabilities. The Company resolved this alleged breach in connection with a series of agreements with Interstate Battery in June 2018.

On January 24, 2019, the Company repaid Interstate Battery the outstanding principal and interest on the convertible debt in the amount of $6.7 million. In connection with the payoff, the Company amortized the remaining discount on the note of $2.6 million and remaining deferred financing expenses of $20,000 to interest expense.
 
Pursuant to the Credit Agreement, the Company also issued to Interstate Battery two common stock purchase warrants, including:

a warrant to purchase 702,247 shares of the Company’s common stock, at an exercise price of $7.12 per share, that was initially exercisable upon grant and initially expired on May 24, 2018; and
a warrant to purchase 1,605,131 shares of the Company’s common stock, at an exercise price of $9.00 per share, that is exercisable commencing November 24, 2016 and expired on May 24, 2019.

The warrants contain cashless exercise and standard anti-dilution adjustment provisions. The first warrant issued was modified in June 2018 to extend the expiration date to June 30, 2020 and reduced the exercise price to $3.33 per share. If Interstate converts its convertible note and exercises both warrants in their entirety, it will own approximately 8.3% of the Company’s common stock at an average price per share of approximately $7.22.
 
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 $5.0 million. 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 note was calculated using an average of the Merrill Lynch US High Yield CCC rate of 16.21% on May 24, 2016 and the Merrill Lynch US High Yield B effective yield of 7.44% on May 24, 2016.
The fair value of the common stock was based on the closing market price of the Company’s common stock on the NASDAQ stock market on 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).
 
  Warrant #1 Warrant #2
Warrant shares issued 702,247    1,605,131   
Market price $ 11.39    $ 11.39   
Exercise price $ 7.12    $ 9.00   
Term (years) 2 years 3 years
Risk-free interest rate 0.91  % 1.05  %
Volatility 65.70  % 67.80  %
Dividend rate —  % —  %
Per share FV of warrant $ 5.89    $ 5.89   
FV of warrant $ 4,136    $ 9,450   

Both warrants were issued on May 24, 2016, when the closing market price of the Company’s 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).

  Fair value Allocated value
Allocation of Proceeds    
Convertible note $ 4,879    $ 1,844   
Warrants 13,586    5,134   
Common stock 7,998    3,022   
  $ 26,463    $ 10,000   
 
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% per annum.
 
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 over the three-year life of the loan. The remaining $629,000 was recorded as a reduction to additional paid-in capital.

Clarios agreement
 
On February 7, 2017, the Company entered into a Stock Purchase Agreement with Clarios pursuant to which the Company issued and sold to a wholly-owned subsidiary of Johnson Controls International plc, (“Johnson Controls”), 939,005 shares of its common stock at $11.33 per share for gross proceeds of approximately $10.6 million. Costs incurred in connection with the transaction, primarily legal fees, totaled approximately $167,000. The Stock Purchase Agreement includes customary representations, warranties, and covenants by Johnson Controls and the Company, and an indemnity from the Company in favor of Johnson Controls.
 
In connection with the investment transactions, the Company also entered into an Investors Rights Agreement dated February 7, 2017 with Johnson Controls pursuant to which the Company granted Johnson Controls customary demand and piggyback registration rights, limited board observation rights and limited preemptive rights allowing Johnson Controls the right to purchase its proportional share of certain future equity issuances by the Company. The board observation and preemptive rights shall expire on the earlier of (i) such time as Johnson Controls no longer owns 50% of the acquired shares or (ii) the termination of both the Tolling/Lead Purchase Agreement and Equipment Supply Agreement.  
 
There were no sales commissions paid by the Company in connection with the sale of its common shares to Johnson Controls.

Veolia Agreement

On February 26, 2019, the Company signed a contract with Veolia North America Regeneration Services LLC ("Veolia") to provide operations, maintenance and management services at Aqua Metals’ AquaRefining facility in McCarran, Nevada. Pursuant to the agreement, Veolia contributes operational and technological expertise and organizational capabilities in aqueous-based process chemistries and electrolysis along with assumption of responsibility for operations, supply chain, offtake and management of the plant. Veolia employees began working onsite starting March 4, 2019 at the McCarran facility.

We also agreed to issue to Veolia, on the one-year anniversary of the agreement, warrants to purchase an additional 2,000,000 shares of our common stock at an exercise price of $5.00 per share and, on the second anniversary of the agreement, warrants to purchase an additional 2,000,000 shares of our common stock at an exercise price $7.00 per share. The warrants will have a term of ten years from the date of issuance.

During the year ended December 31, 2019, the Company issued 1,184,985 shares of common stock valued at $3.6 million to Veolia North America Regeneration Services, LLC pursuant to the Operations, Maintenance and Management Agreement between Veolia and the Company.

Warrants issued

In January 2019, the Company issued a warrant to purchase 103,500 shares of the Company's common stock to the underwriter of the Company's January 22, 2019 public offering, equal to 2% of the 5,175,000 shares sold. The warrant is exercisable at $1.90 per share (100% of the price of the common stock sold in the offering), commencing the later of six months after January 22, 2019 or such time as the Company amends its charter to increase its authorized shares of common stock. The warrant will expire on January 22, 2024.

Pursuant to the Operations, Maintenance and Management Agreement dated February 26, 2019, the Company has agreed to issue to Veolia, on the one-year anniversary of the Agreement, warrants to purchase 2,000,000 shares of its common stock at an exercise price of $5.00 per share and, on the second anniversary of the Agreement, warrants to purchase an additional 2,000,000 shares of its common stock at an exercise price $7.00 per share. The warrants will have a term of ten years from the date of issuance. The warrants were valued as of the agreement date using the Black-Scholes-Merton pricing model. The value of the warrants is being amortized over the applicable period until the warrants are issued.
 
The following assumptions were used in the Black-Scholes-Merton pricing model to estimate the fair value of the warrants (FV of warrants in thousands).
  Veolia Warrant #1 Veolia Warrant #2 Jan. 2019 Offering Underwriter

FV of warrant $ 4,699    $ 4,474    $ 152   
 
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 2,307,378 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.
 

Warrant modification

On June 24, 2018, the Company entered into a series of agreements with Interstate Battery, which modified the terms of a warrant to purchase 702,247 shares of our common stock by reducing the exercise price of the warrant from $7.12 per share to $3.33 per share and extended the expiration date of the warrant from June 24, 2018 to June 23, 2020. The expiration date had previously been extended from May 2018 to June 2018 as part of the overall negotiations. The incremental fair value resulting from this modification was calculated to be $1.0 million using the Black-Scholes-Merton Option Pricing Model with the assumptions as follows: $3.26 per share fair value on the date of modification; 2-year term; 80.2% volatility; 2.56% discount rate and 0% annual dividend rate.
The Company previously recorded $0.6 million in general and administrative expense during the year ended December 31, 2017 with the offset in accrued liabilities as an estimate of this liability. Upon modification, the Company recorded an additional $4 million in general and administrative expense for the three months ended June 30, 2018 and relieved $0.6 million in accrued liabilities with the $1.0 million offset to additional paid-in capital.

Stock-based compensation
 
In 2014, the Board of Directors adopted the Company’s stock incentive plan (the “2014 Plan”). The 2014 Plan was most recently amended and restated effective as of the Company’s 2017 Annual Stockholders’ Meeting. A total of 2,113,637 shares of common stock was authorized for issuance pursuant to the 2014 Plan at the time of its most recent amendment and restatement in 2017. 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.

In 2019, the Board of Directors adopted the Company’s stock incentive plan (the “2019 Plan”). A total of 4,500,000 shares of common stock was authorized for issuance pursuant to the 2019 Plan. The 2019 Plan provides for the following types of stock-based awards: incentive stock options; non-statutory stock options; restricted stock; and performance stock. The 2019 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.

Dividend yield —  % —  %
 
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. Forfeitures are recognized as they occur.
