1. Organization

Description of Business

Ekso Bionics Holdings, Inc. (the “Company”) designs, develops and sells exoskeleton technology to augment human strength, endurance and mobility. The Company’s exoskeleton technology serves multiple markets and can be used both by able-bodied users as well as by persons with physical disabilities. The Company has sold, rented or leased devices that (a) enable individuals with neurological conditions affecting gait (stroke and spinal cord injury) to rehabilitate and to walk again and (b) allow industrial workers to perform heavy duty work for extended periods. Founded in 2005, the Company is headquartered in the Bay Area and is listed on the Nasdaq Capital Market under the symbol “EKSO”.

Liquidity and Going Concern

As of March 31, 2018, the Company had an accumulated deficit of $152,055.  Largely as a result of significant research and development activities related to the development of the Company’s advanced technology and commercialization of this technology into its medical device business, the Company has incurred significant operating losses and negative cash flows from operations since inception. The Company has also recognized significant non-cash losses in previous periods associated with the revaluation of certain securities, which have contributed significantly to its accumulated deficit. In the three months ended March 31, 2018, the Company used $6,745 of cash in its operations.

Cash on hand at March 31, 2018 was $20,572, compared to $27,813 at December 31, 2017. As noted in Note 9, Long-Term Debt, borrowings under the Company’s long-term debt agreement have a requirement of minimum cash on hand roughly equivalent to three months of cash burn. As of March 31, 2018, the most recent determination of this restriction, $5,526 of cash must remain as unrestricted, with such amounts to be re-computed at each month end period. After considering cash such restriction, effective unrestricted cash as of March 31, 2018 is estimated to be $15,046. Based on current forecasted amounts, the Company’s cash on hand will not be sufficient to satisfy the Company’s operations for the next twelve months from the date of issuance of these condensed consolidated financial statements, which raises substantial doubt about the Company’s ability to continue as a going concern.

Based upon the Company’s current cash resources, the recent rate of using cash for operations and investment, and assuming modest increases in current revenue offset by incremental increases in expenses related to increased sales and marketing and research and development, and a potential increase in rental activity from its medical device business, the Company believes it has sufficient resources to meet its financial obligations into the first quarter of 2019. The Company will require significant additional financing. The Company is actively pursuing opportunities to obtain additional financing in the future through public or private equity and/or debt financings, corporate collaborations, or warrant solicitations.  

The Company’s actual capital requirements may vary significantly and will depend on many factors. The Company plans to continue its investments (i) in its clinical and sales initiatives to accelerate adoption of the Ekso robotic exoskeleton in the rehabilitation market, (ii) in its research, development and commercialization activities with respect to an Ekso robotic exoskeleton for home use, and/or (iii) in the development and commercialization of able-bodied exoskeletons for industrial use. Consequently, the Company may require significant additional financing in the future, which the Company intends to raise through corporate collaborations, public or private equity offerings, debt financings, or warrant solicitations. Sales of additional equity securities by the Company could result in the dilution of the interests of existing stockholders. There can be no assurance that financing will be available when required in sufficient amounts, on acceptable terms or at all. In the event that the necessary additional financing is not obtained, the Company may be required to further reduce its discretionary overhead costs substantially, including research and development, general and administrative, and sales and marketing expenses or otherwise curtail operations.   

2. Basis of Presentation and Summary of Significant Accounting Policies and Estimates

Basis of Presentation

In the opinion of management, the accompanying unaudited condensed consolidated financial statements have been prepared on a consistent basis with the audited consolidated financial statements for the fiscal year ended December 31, 2017, and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state the information set forth herein. The condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) and therefore, omit certain information and footnote disclosure necessary to present the financial statements in accordance with generally accepted accounting principles in the United States (“GAAP”). These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017, which was filed with the SEC on March 13, 2018. The results of operations for the three months ended March 31, 2018 are not necessarily indicative of the results to be expected for the entire fiscal year or any future periods.

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the balance sheet, and the reported amounts of revenues and expenses during the reporting period. For the Company, these estimates include, but are not limited to: revenue recognition, deferred revenue and the deferral of the associated costs, future warranty costs, maintenance and planned improvement costs associated with medical device units sold prior to 2016, useful lives assigned to long-lived assets, realizability of deferred tax assets, the valuation of options and warrants, and contingencies. Actual results could differ from those estimates.

Inventory

Inventories are recorded at the lower of cost or net realizable value. Cost is determined using the standard cost method. Parts from vendors are received and recorded as raw material. Once the raw materials are incorporated in the fabrication of the product, the related value of the component is recorded as work in progress (“WIP”). Direct labor and manufacturing overhead costs are also allocated and recorded to WIP inventory. Finished goods are comprised of completed products that are ready for customer shipment. The Company periodically evaluates the carrying value of inventory on hand for potential excess amounts over sales and forecasted demand. Excess and obsolete inventories identified, if any, are recorded as an inventory impairment charge to the consolidated statements of operations and comprehensive loss. The Company’s estimate of write downs for excess and obsolete inventory is based on a detailed analysis of on-hand inventory and purchase commitments in excess of forecasted demand.  Subsequent disposals of inventories are recorded as a reduction of an inventory reserve.

Revenue Recognition

Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company enters into contracts that can include various combinations of products and services, which when capable of being distinct, are accounted for as separate performance obligations.

Nature of Products and Services

The Company’s medical device segment revenue is generated through the sales of the Ekso GT, associated software (SmartAssist, VariableAssist), accessories, and support and maintenance contracts (Ekso Care). Revenue from medical device product sales is recognized at the point in time when control of the product transfers to the customer. Transfer of control generally occurs upon shipment from the Company’s facility for sales of the Ekso GT, software and accessories. Ekso Care support and maintenance contracts extend coverage beyond the Company’s standard warranty agreements. The separately priced Ekso Care contracts range from 12 to 48 months. The Company receives payment at the inception of the contract and recognize revenue over the term of the agreement.

The Company’s industrial device segment revenue is generated by the sales of the support arm (EksoZeroG) and the upper body exoskeleton (EksoVest). Revenue from industrial device sales is recognized at the point in time when control of the product transfers to the customer. Transfer of control generally occurs upon shipment from the Company’s facility for sales of the EksoZeroG and EksoVest.

The Company’s engineering services segment revenue is generated by collaborative arrangements or government grants. Cost reimbursements or grant revenue are recognized over the life of the contract in proportion to the costs incurred in satisfying the obligations under the contract.

Refer to Note 6 – Revenue Recognition for further information, including revenue disaggregated by source.

Going Concern

The Company assesses its ability to continue as a going concern at every interim and annual period in accordance with Accounting Standards Codification 205-40. The accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern.

Concentration of Credit Risk and Other Risks and Uncertainties

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and accounts receivable. The Company maintains its cash accounts in excess of federally insured limits. However, the Company believes it is not exposed to significant credit risk due to the financial position of the depository institutions in which these deposits are held. The Company extends credit to customers in the normal course of business and performs ongoing credit evaluations of its customers. Concentrations of credit risk with respect to accounts receivable exist to the full extent of amounts presented in the consolidated financial statements. The Company does not require collateral from its customers to secure accounts receivable.

Accounts receivable are derived from the sale of products shipped to and services performed for customers. Invoices are aged based on contractual terms with the customer. The Company reviews accounts receivable for collectability and records an allowance for credit losses, as needed. The Company has not experienced any material losses related to accounts receivable as of March 31, 2018 and December 31, 2017.

Many of the sales contracts with customers outside of the U.S. are settled in a foreign currency. The Company does not enter into any foreign currency hedging agreements and is susceptible to gains and losses from foreign currency fluctuations. To date, the Company has not experienced significant gains or losses upon settling foreign currency denominated accounts receivable.

As of March 31, 2018, the Company had one customer with an accounts receivable balance totaling 10% or more of the Company’s total accounts receivable (15%) compared with one customer as of December 31, 2017 (10%).

In the three months ended March 31, 2018, the Company had one customer with sales of 10% or more of the Company’s total revenue (11%), compared with one customer in the three months ended March 31, 2017 (26%).

 
Recent Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) which will require lessees to recognize assets and liabilities for leases with lease terms of more than 12 months. For finance leases, a lessee is required to: (1) recognize a right-of-use asset and a lease liability, initially measured at  the present value of the lease payments, in the statement of financial position, (2) recognize interest on the lease liability separately from amortization of the right-of-use asset in the statement of comprehensive income, and (3) classify repayments of the principal portion of the lease liability within financing activities and payments of interest on the lease liability and variable lease payments within operating activities in the statement of cash flows. For operating leases, a lessee is required to: (1) recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position, (2) recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a generally straight-line basis, and (3) classify all cash payments within operating activities in the statement of cash flows. The new guidance is effective for fiscal years beginning after December 15, 2018.  The Company is evaluating the impact that ASU 2016-02 will have on its consolidated financial statements and related disclosures.

In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment. ASU 2017-04 eliminated the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities are required to record an impairment charge based on the excess of the carrying amount over its fair value. The new standard will be effective for the Company beginning January 1, 2020 and early adoption is permitted. The Company does not expect the impact of adopting ASU 2017-04 to be material on its consolidated financial statements.

Recently Adopted Accounting Standards

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). The updated standard will replace most existing revenue recognition guidance in U.S. GAAP. The new standard introduces a five-step process to be followed in determining the amount and timing of revenue recognition. It also provides guidance on accounting for costs incurred to obtain or fulfill contracts with customers, and establishes disclosure requirements which are more extensive than those required under prior U.S. GAAP. The FASB has issued numerous amendments to ASU 2014-09 from August 2015 through January 2018, which provide supplemental and clarifying guidance, as well as amend the effective date of the new standard. ASU 2014-09, as amended, is effective for the Company in the first quarter of 2018. The standard permits the use of either the retrospective or modified retrospective (cumulative effect) transition method. Effective January 1, 2018, the Company adopted the new standard using the modified retrospective transition method. The adoption did not result in a cumulative adjustment to the Company’s consolidated balance sheet as of January 1, 2018, nor did it materially impact the aggregate amount and timing of the Company’s revenue recognition subsequent to adoption. The Company has provided enhanced revenue recognition disclosures as required by the new standard (Refer to Note 6, Revenue Recognition).

3. Accumulated Other Comprehensive Loss

The change in accumulated other comprehensive loss presented on the condensed consolidated balance sheets and the impact of significant amounts reclassified from accumulated other comprehensive (loss) income on information presented in the condensed consolidated statements of operations and comprehensive loss for the three months ending March 31, 2018 are reflected in the table below, net of tax:

	Foreign Currency Translation
Balance at December 31, 2017	$	(340)
Other comprehensive loss before reclassification		(207)
Balance at March 31, 2018	$	(547)

4. Fair Value Measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Three levels of inputs, of which the first two are considered observable and the last unobservable, may be used to measure fair value which are the following:

• Level 1—Quoted prices in active markets for identical assets or liabilities. The Company considers a market to be active when transactions for the asset occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

• Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

• Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The valuation of Level 3 investments requires the use of significant management judgments or estimation.

6. Revenue Recognition

Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company enters into contracts that can include various combinations of products and services, which when capable of being distinct, are accounted for as separate performance obligations. Revenue recognition is evaluated based on the following five steps: (i) identification of the contract with the customer; (ii) identification of the performance obligations in the contract; (iii) determination of the transaction price; (iv) allocation of the transaction price to the performance obligations in the contract; and (v) recognition of revenue when or as a performance obligation is satisfied.

Notes to Condensed Consolidated Financial Statements

($ and share amounts in thousands, except per share amounts)

(Unaudited)

For multiple-element arrangements, revenue is allocated to each performance obligation based on its relative standalone selling price. Standalone selling prices are determined based on observable prices at which the Company separately sells its products or services. If a standalone selling price is not directly observable, the Company estimates the selling price based on market conditions and entity-specific factors including features and functionality of the product and/or services, the geography of our customers, type of the Company’s markets. Any discounts or other reductions to the transaction price are allocated proportionately to all performance obligations within the multiple-element arrangement.

Contract Balances  

Timing of revenue recognition may differ from the timing of invoicing to customers and receipt of payment. For the sale of its products, the Company generally recognizes revenue at a point in time through the ship-and-bill performance obligations. For service agreements, the Company generally invoices customers at the beginning of the coverage period and record revenue related to the billed amounts over time, equivalent to the coverage period of the maintenance and support contract.

Deferred revenue is comprised mainly of unearned revenue related to extended support and maintenance contracts (Ekso Care) but also includes other offerings for which the Company has been paid in advance and earn revenue when the Company transfers control of the product or service.

Deferred revenues consisted of the following:

	March 31,			December 31,
	2018			2017
Deferred extended maintenance and support	$	1,903		$	1,763

Ending balance	$	2,058

At March 31, 2018, our deferred revenue, was $2,058. Excluding customer deposits, we expect to recognize approximately $712 of the deferred revenue in the remainder of 2018, $543 in 2019, and $754 thereafter. 

As of March 31, 2018, and December 31, 2017, accounts receivable, net of allowance for doubtful accounts, were $3,574 and $2,760, respectively, and are included in current assets on the Company’s consolidated balance sheets.

The allowance for doubtful accounts reflects the Company’s best estimate of probable losses inherent in the accounts receivable balance. The Company determines the allowance based on known troubled accounts, historical experience, and other currently available evidence. Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 to 60 days.

9. Long-Term Debt

In December 2016, the Company entered into a loan agreement and received $7,000 that bears interest on the outstanding daily balance at a floating per annum rate equal to the 30-day U.S. LIBOR plus 5.41%. The loan agreement created a first priority security interest with respect to substantially all assets of the Company, including proceeds of intellectual property, but expressly excluding intellectual property itself.

The Company was required to pay accrued interest on the current loan on the first day of each month through and including January 1, 2018. Commencing on February 1, 2018, the Company is required to make equal monthly payments of principal, together with accrued and unpaid interest. The principal balance of the current loan amortizes ratably over 36 months, and matures on January 1, 2021, at which time all unpaid principal and accrued and unpaid interest shall be due and payable in full. In addition, a final payment of $245 will be due on the maturity date, of which $120 has accreted as of March 31, 2018, to be paid in 2021 and is included as a component of note payable on the Company’s condensed consolidated balance sheets.

In December 2016, and pursuant to the loan agreement, the Company entered into a success fee agreement with the lender under which the Company agreed to pay the lender a $250 success fee upon the first to occur of any of the following events: (a) a sale or other disposition by the Company of all or substantially all of its assets; (b) a merger or consolidation of the Company into or with another person or entity, where the holders of the Company’s outstanding voting equity securities immediately prior to such merger or consolidation hold less than a majority of the issued and outstanding voting equity securities of the successor or surviving person or entity immediately following the consummation of such merger or consolidation; or (c) the closing price per share for the Company’s common stock being $8.00 or more for five successive business days. The estimated fair value of the success fee was determined using the Binomial Lattice Model and was recorded as a discount to the debt obligation. The fair value of the contingent success fee is re-measured each reporting period with any adjustments in fair value being recognized in the consolidated statements of operations and comprehensive loss. The success fee is classified as a liability on the condensed consolidated balance sheets. At March 31, 2018, the fair value of the contingent success fee liability was $40.

The loan agreement includes a liquidity covenant requiring that the Company maintain unrestricted cash and cash equivalents in accounts of the lender or subject to control agreements in favor of the lender in an amount equal to at least three months of “Monthly Cash Burn,” which is the Company’s average monthly net income (loss) for the trailing six-month period plus certain expenses and plus the average monthly principal due and payable on interest-bearing liabilities in the immediately succeeding three-month period. Such amount was determined to be $5,526 as of March 31, 2018, the most current determination, with the amount subject to change on a month-to-month basis. At March 31, 2018, with cash on hand of $20,572, the Company was compliant with this liquidity covenant and all other covenants.

The final payment fee, debt issuance costs, and the initial fair value of the success fee combined with the stated interest resulted in an effective interest rate of 9.67% for the three months ended March 31, 2018. The final payment fee, initial fair value of the success fee and debt issuance costs was and will be accreted, amortized and amortized, respectively, to interest expense using the effective interest method over the life of the loan.

The following table presents scheduled principal payments of our long-term debt and final payment fee as of March 31, 2018:

Period	Amount
2018	$	1,750
2019		2,333
2020		2,333
2021		440
Total principal payments		6,856
Less accreted portion of final payment fee, net of issuance cost and success fee discounts		233
Long-term debt, net	$	6,623
Current portion		2,333
Long-term portion		4,290
Long-term debt, net	$	6,623

10. Lease Obligations

In May 2017, the Company renewed its operating lease agreement for its headquarters and manufacturing facility in Richmond, California. The new lease term will expire in May 2022.

In July 2017, the Company entered into an operating lease agreement for its European operations office in Hamburg, Germany. The initial Hamburg lease term will expire in July 2022, and the Company has an option to extend the lease for another five-year term. The Company continues to lease an office in Freiburg with plans to sublease the office in 2018. The Freiburg lease term will expire in December 2020.

In August 2015, the Company entered into a long-term capital lease obligation for equipment. The aggregate principal of the lease is $166, with an interest rate of 4.7%, minimum monthly payments of $3 and a July 1, 2020 maturity. This capital lease is classified as a component of accrued liabilities and other non-current liabilities in the consolidated balance sheets.

The Company estimates future minimum payments as of March 31, 2018 to be the following:

Period	Capital Lease			Operating Leases
2018 – remainder	$	28		$	473
2019		37			643
2020		22			656
2021		-			576
2022		-			268
Total minimum payments		87		$	2,616
Less interest		(5	)
Present value minimum payments		82
Less current portion		(34	)
Long-term portion	$	48

Rent expense under the Company’s operating leases was $143 and $101 for the three months ended March 31, 2018, and 2017, respectively.

11. Capitalization and Equity Structure

Summary

The Company’s authorized capital stock at March 31, 2018 consisted of 141,429 shares of common stock and 10,000 shares of preferred stock. At March 31, 2018, 60,355 shares of common stock were issued and outstanding and no shares of preferred stock were issued and outstanding.

On October 30, 2017, the Board approved an amendment to the Company’s Articles of Incorporation to increase the number of shares of our common stock by 70,000 shares to 141,429 shares (the “Authorized Capital Amendment”), subject to the approval of such amendment by the stockholders. On December 21, 2017, a special meeting of the stockholders was convened (the “December Special Meeting”). In the definitive proxy statement dated November 24, 2017 filed by the Company with the SEC in respect of the December Special Meeting (the “November Proxy Statement”), the Board solicited the vote of the stockholders in favor of the Authorized Capital Amendment. The November Proxy Statement stated that broker non-votes in respect of the Authorized Capital Amendment would be counted as votes against the amendment. However, under relevant stock exchange rules, brokers had the discretionary authority to vote any shares held in their name on behalf of a beneficial owner (“Broker Shares”), and in respect of which the broker did not receive voting instruction from the beneficial owner, in favor of the Authorized Capital Amendment. As such, brokers voted approximately 17,628 Broker Shares, in respect of which the brokers had not received voting instructions from the beneficial owners of such shares, in favor of the Authorized Capital Amendment at the December Special Meeting. Accordingly, after taking into account such Broker Shares, the Authorized Capital Amendment was approved by the stockholders at the December Special Meeting. However, as disclosed in more detail under Item 3 in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, some stockholders of the Company have claimed that the disclosure in the November Proxy Statement in connection with the effect on the Authorized Capital Amendment of beneficial owners not providing voting instructions in respect of their Broker Shares was incorrect. Accordingly, management has solicited stockholders to ratify the Authorized Capital Amendment at our 2018 Annual Meeting of Shareholders, which will be held on June 7, 2018 (the “2018 Annual Meeting”). Further information about such vote was provided in the Company’s Definitive Proxy Statement relating to its 2018 Annual Meeting of Shareholders, which was filed with the SEC on April 30, 2018 (the “2018 Proxy Statement”).

Warrants

Warrant shares outstanding as of December 31, 2017 and March 31, 2018 were as follows:

Source	Exercise Price		Term (Years)		December 31, 2017		Issued		Expired		March 31, 2018

						3,396		-		-		3,396

Information Agent Warrants

In September 2017, in connection with the Rights Offering in August of 2017, the Company issued warrants to purchase 200 shares of the Company’s common stock with an exercise price of $1.50 to an information agent (the “Information Agent Warrants”). The Information Agent Warrants became exercisable immediately upon issuance. These warrants were recorded in stockholders’ equity on the Company’s condensed consolidated balance sheet.

2015 Warrants

In December 2015, the Company issued warrants to purchase 2,122 shares with an exercise price of $3.74 per share (the “2015 Warrants”). The 2015 Warrants contain a put-option provision. Under this provision, while the 2015 Warrants are outstanding, if the Company enters into a Fundamental Transaction, defined as a merger, consolidation or similar transaction, the Company or any successor entity will, at the option of each warrant holder, exercisable at any time within 30 days after the consummation of the Fundamental Transaction, purchase the warrant from the holder exercising such option by paying to the holder an amount of cash equal to the Black-Scholes value of the remaining unexercised portion of such holder’s warrant on the date of the consummation of the Fundamental Transaction. Because of this put-option provision, the 2015 Warrants are classified as a liability and are marked to market at each reporting date.

The warrant liability related to the 2015 Warrants is measured at fair value at each reporting date using certain estimated inputs, which are classified within Level 3 of the fair value hierarchy. The following assumptions were used in the Black Scholes Option Pricing Model to measure the fair value of the 2015 warrants as of March 31, 2018:

Current share price	$	1.58
Conversion price	$	3.74
Risk-free interest rate		2.36	%
Term (years)		2.75
Volatility of stock		90	%

12. Stock-based Compensation

In June 2017, the Company’s stockholders approved an amendment of the Company’s Amended and Restated 2014 Equity Incentive Plan (the “2014 Plan”) to increase the number of shares available for grant by 1,000 shares.  The total shares authorized for grant under the 2014 Plan is 4,714.

On October 30, 2017, the Board approved an amendment to the 2014 Plan to increase the maximum number of shares of common stock that may be issued under the 2014 Plan by 4,400 shares, from 4,714 to 9,114 shares (the “2014 Plan Amendment”) effective as of the time such amendment is approved by the stockholders. At the December Special Meeting, a proposal was submitted to be voted on by the stockholders to approve the 2014 Plan Amendment contingent on the approval by the stockholders of the Authorized Capital Amendment. The proposal was approved by the stockholders at the December Special Meeting, with approximately 25,205 shares voted for, 2,955 shares voted against, and 356 shares abstaining. However, since the proposal was contingent on the approval by the stockholders of the Authorized Capital Amendment, management has solicited stockholders to ratify the 2014 Plan Amendment at the 2018 Annual Meeting. Further information is provided in the 2018 Proxy Statement.

As of March 31, 2018, there were 5,162 shares available for future awards after taking into account the 2014 Plan Amendment.

As of March 31, 2018, total unrecognized compensation cost related to unvested stock options was $1,809. This amount is expected to be recognized as stock-based compensation expense in the Company’s condensed consolidated statements of operations and comprehensive income over the remaining weighted average vesting period of 2.29 years.

The per-share fair value of each stock option was determined on the date of grant using the Black-Scholes option pricing model using the following assumptions:

	Three months ended March 31,

Restricted Stock Units

Beginning in 2017, the Company issued restricted stock units (“RSUs”), to employees and non-employees as permitted by the 2014 Plan. Each restricted stock unit corresponds to one share of the Company’s common stock and becomes issuable upon vesting. The fair value of restricted stock units is determined based on the closing price of the Company’s common stock on the date of grant.

RSU activity for the three months ended March 31, 2018 is summarized below:

	Number of Shares			Weighted- Average Grant Date Fair Value
Unvested as of January 1, 2018		617		$	1.65
Granted		35		$	1.73
Vested		(466	)	$	1.32
Forfeited		(61	)	$	2.85
Unvested at March 31, 2018		125		$	2.27

As of March 31, 2018, $159 of total unrecognized compensation expense related to unvested RSUs was expected to be recognized over a weighted average period of 2.96 years.

Compensation Expense

Total stock-based compensation expense related to options and RSUs granted to employees and non-employees is included in the condensed consolidated statements of operations and comprehensive loss as follows:

	Three months ended March 31,
	2018		2017
Sales and marketing	$	109	$	20
Research and development		179		101
General and administrative		604		273
	$	892	$	394

401(k) Plan Share Match

In August 2017, the Company’s Board of Directors approved a match benefit to the Ekso Bionics 401(k) plan (the “401(k) Plan”) in the form of shares of the Company’s common stock. The Company will make a matching contribution to the 401(k) Plan in an amount equal to 100% of each eligible employee’s elected deferral (up to the statutory limit) for the year ending December 31, 2017 and equal to 50% of each employee’s elected deferral for each year thereafter.

During the three months ended March 31, 2018, the Company issued 221 shares of common stock to each eligible employee’s deferral account for the 401(k) Plan matching contribution for the year ended December 31, 2017.

13. Income Taxes

There were no material changes to the unrecognized tax benefits in the three months ended March 31, 2018, and the Company does not expect significant changes to unrecognized tax benefits through the end of the fiscal year. Because of the Company’s history of tax losses, all years remain open to tax examination.

14. Commitments and Contingencies

Material Contracts

The Company enters various license, research collaboration and development agreements which provide for payments to the Company for government grants, fees, cost reimbursements typically with a markup, technology transfer and license fees, and royalty payments on sales.

The Company has two license agreements with the Regents of the University of California to maintain exclusive rights to certain patents. Pursuant to those license agreements, the Company is required to pay 1% of net sales of products sold to entities other than the U.S. government and, in the event of a sub-license, the Company will owe 21% of license fees and must pass through 1% of the sub-licensee’s net sales of products sold to entities other than the U.S. government. The agreements also stipulate minimum annual royalties of $50.

In connection with acquisition of Equipois, the Company assumed the rights and obligations of Equipois under a license agreement with the developer of certain intellectual property related to mechanical balance and support arm technologies, which grants the Company an exclusive license with respect to the technology and patent rights for certain fields of use. Pursuant to the terms of the license agreement, the Company pays the developer a single-digit royalty on net receipts, subject to a $50 annual minimum royalty requirement.

Contingencies

In the normal course of business, the Company is subject to various legal matters. In the opinion of management, the resolution of such matters will not have a material adverse effect on the Company’s condensed consolidated financial statements.

15. Net Loss Per Share

16. Segment Disclosures

The Company has three reportable segments: Medical Devices, Industrial Sales, and Engineering Services. The Medical Devices segment designs and engineers technology for, and commercializes, manufactures, and sells exoskeletons for applications in the medical markets. The Industrial Sales segment designs, engineers, commercializes, manufactures, and sells exoskeleton devices to allow able-bodied users to perform heavy duty work for extended periods. Engineering Services generates revenue principally from collaborative research and development service arrangements, technology license agreements, and government grants where the Company uses its robotics domain knowledge in bionic exoskeletons to bid on and procure contracts and grants from entities such as the National Science Foundation and the Defense Advanced Research Projects Agency.

The Company evaluates performance and allocates resources based on segment gross profit margin. The reportable segments are each managed separately because they serve distinct markets, and one segment provides a service and the others manufacture and distribute unique products. The Company does not consider net assets as a segment measure and, accordingly, assets are not allocated.

Segment reporting information is as follows:

Overview

We design, develop and sell exoskeleton technology to augment human strength, endurance and mobility. Our exoskeleton technology serves multiple markets and can be used both by able-bodied users as well as by persons with physical disabilities. We have sold, rented or leased devices that (a) enable individuals with neurological conditions affecting gait (stroke and spinal cord injury) to rehabilitate and to walk again and (b) allow industrial workers to perform heavy duty work for extended periods.

Today, our medical exoskeleton, Ekso GT, is used as a rehabilitation tool to allow physicians and therapists to rehabilitate patients who have suffered a stroke or spinal cord injury. With its unique features designed specifically for hospitals and its proprietary SmartAssist software, Ekso GT allows for the early mobilization of patients, with high step count and high dosage treatments. The intent is to allow the patient’s central nervous system to take advantage of a person’s neuroplasticity to maximize a patient’s recovery.

For able-bodied industrial workers, we introduced in 2017 a second commercial product for industrial applications, the EksoVest, an upper body exoskeleton that elevates and supports a worker's arms to assist them with tasks ranging from chest height to overhead. It is lightweight and low profile, making it comfortable to wear in all conditions while enabling freedom of motion. The goal is for workplaces with the EksoVest to experience fewer on-site injuries while tasks are completed faster and with higher quality results, for workers to stay healthier and experience increased stamina, and for companies to gain greater productivity in factories and on construction sites. In 2018, we are focusing on increasing sales of the EksoVest and EksoZeroG by pursuing alternative channels such as rental agreements with construction equipment and heavy tool providers. In addition, we believe there is additional mid-to-long-term potential in the industrial markets, and accordingly, we will continue our development efforts to expand our EksoWorks product offerings.

We believe the commercial opportunity for exoskeleton technology adoption is accelerating as a result of recent advancements in material technologies, electronic and electrical engineering, control technologies, and sensor and software development. Taken individually, many of these advancements have become ubiquitous in peoples’ everyday lives. We believe that we have learned how to integrate these existing technologies and wrap the result around a human being efficiently, elegantly and safely, supported by an industry leading intellectual property portfolio. We further believe that we can do so across a broad spectrum of applications, from persons with lower limb paralysis to able-bodied users.

Clinical Update

Our strategy continues to be to expand clinical data associated with robotic exoskeleton use and, in particular, Ekso GT. To date, there have been 79 studies announced utilizing the Ekso GT, including 48 completed studies and 31 ongoing studies, encompassing a total of over 1,700 patients. This includes our first sponsored clinical trial, which is led by Professor Dylan Edwards, Ph.D., P.T., of The Burke Medical Research Institute. The study, entitled WISE (Walking Improvement for SCI with Exoskeletons), evaluates improvement in independent gait speeds of Spinal Cord Injury (“SCI”) patients undergoing rehabilitation with the Ekso GT and compares it to both conventional therapy and a control group. The U.S.-based, multi-center study has been initiated at ten rehabilitation centers and seeks to enroll approximately 160 people with chronic incomplete SCI. The primary endpoint of the WISE study seeks to demonstrate that a 12-week robotic gait training regimen can lead to a clinically meaningful improvement in independent walking speed. Secondary endpoints from the trial are examining economic factors such as number of physical therapists and staff required during training, the physical burden on physical therapists assisting and supervising during training, and the influence of factors that may modify the gait recovery.

We also continue to work with investigators who have independently initiated large clinical trials to study the use of the Ekso GT, including: a Kessler Foundation study that is enrolling acute stroke patients in a grant-funded randomized, controlled trial with the goal of demonstrating the benefits of early intervention with gait therapy using the Ekso GT; a registry headed up by the Rehabilitation Institute of Chicago focusing on the clinical efficacy of the Ekso GT in both SCI and stroke survivors; and a study being conducted by the Moritz Klink entitled The MOST Study (Mobility improved after stroke when a robotic device was used in comparison to physical therapy) investigating the impact of gait training with the Ekso GT on functional independence of 80 patients with impaired gait as a consequence of stroke when compared to conventional physiotherapy alone.

Sales and Marketing Update - Rehabilitation

In conjunction with our Food and Drug Administration (“FDA”) clearance in April 2016, including the first approved label in the industry that includes patients with hemiplegia due to stroke, we completed a full review of our sales and marketing efforts. We have begun to broaden the launch of our Ekso GT and our go-to-market plan in the U.S. and in Europe, including an increase in marketing campaigns to educate the market on the benefits of stroke rehabilitation using exoskeletons, and arranging product demonstrations with various stakeholders at our target customers.

22 

Today we have five direct salespersons, one direct sales representative for Germany and Switzerland and a distributor manager for 15 distributors in Europe, the Middle East, and Africa (“EMEA”), covering 25 markets, as well as a sales operations manager that supports the efforts of both regions. This sales team is supported by 10 physical therapists to provide customer demonstrations and training, and six sales operation and customer service personnel. Over the past several quarters the Company has endeavored to better understand its customer’s decision cycle for adopting the Company’s new technology, in order to optimize the pace of placements and adoption, and has piloted a number of alternative approaches for trial, sales, and rental options. For example, in the United States and EMEA, we have piloted a short-term (12- months) customer rental with an option to convert to purchase or long-term rental to place units with customers, which in several cases has been more effective than pursuing sales through the standard capital purchase budget cycle. Given the track record of converting previous rentals to sales, we could see these short-term rentals in the United States and other operating rental options facilitate expansion of the Company’s rehabilitation program, while also allowing us to reduce the timeline to place our Ekso GT units.

Recently we launched our Centers of Excellence program in both the U.S. and Europe, a unique peer-to-peer program through which some of our key customers and thought leaders share their knowledge and experience with potential and new customers. The program spans the operational areas of clinical, sales and marketing to bring together the user experience and share it with new customers to facilitate adoption and utilization. These Centers of Excellence will work with our integrated sales and marketing teams and will be available to prospective customers/partners to discuss the clinical, business and financial merits of using the Ekso GT as a tool in rehabilitation. These Centers of Excellence complement the more than 175 hospitals and clinics that already have incorporated over 300 Ekso GT units in their rehabilitation programs.

We have been granted 35 Continuing Competence Units, through the Federation of State Board of Physical Therapy (FSBPT), for physical therapists that successfully complete the Ekso GT training program. The FSBPT recognized the comprehensive overview of gait analysis, robotic technology integration into gait training, and interactive learning through guided instruction during our training program.

Regulatory Status

On April 4, 2016, we received clearance from the FDA to market our Ekso GT robotic exoskeleton for use in the treatment of individuals with hemiplegia due to stroke, individuals with spinal cord injuries at levels T4 to L5, and individuals with spinal cord injuries at levels of T3 to C7 (ASIA D), in accordance with the device’s labeling. On July 19, 2016, we received clearance from the FDA to expand/clarify the indications and labeling to expressly include individuals with hemiplegia due to stroke who have upper extremity function of at least 4/5 in only one arm. Our prior cleared indications for use statement required that individuals with hemiplegia due to stroke have upper extremity function of at least 4/5 in both arms.

The U.S. government regulates the medical device industry through various agencies, including but not limited to, the FDA, which administers the Federal Food, Drug, and Cosmetic Act. The FDA classifies medical devices into one of three classes (Class I, II or III) based on the degree of risk the FDA determines to be associated with a device and the extent of control deemed necessary to ensure the device’s safety and effectiveness. Devices requiring fewer controls because they are deemed to pose lower risk are placed in Class I or II. Class I devices are deemed to pose the least risk and are subject only to general controls applicable to all devices, such as requirements for device labeling, premarket notification, and adherence to the FDA’s current good manufacturing practice requirements, as reflected in its Quality System Regulation (“QSR”). Class II devices are intermediate risk devices that are subject to general controls and may also be subject to special controls such as performance standards, product-specific guidance documents, special labeling requirements, patient registries or post-market surveillance. Class III devices are those for which insufficient information exists to assure safety and effectiveness solely through general or special controls, and include life-sustaining, life-supporting, or implantable devices, and devices not “substantially equivalent” to a device that is already legally marketed. Most Class I devices, and some Class II devices are exempted by regulation from the 510(k) clearance requirement and can be marketed without prior authorization from FDA. Class I and Class II devices that have not been so exempted are eligible for marketing through the 510(k) clearance pathway. By contrast, devices placed in Class III generally require premarket approval, or PMA, prior to commercial marketing.

We believe that prior to April 4, 2016, our Ekso GT robotic exoskeleton had been appropriately marketed as a Class I 510(k) exempt Powered Exercise Equipment device since February 2012. On June 26, 2014, the FDA announced the creation of a new product classification for Powered Exoskeleton devices. On October 21, 2014, the FDA published the summary for the new Powered Exoskeleton classification and designated it as being Class II, which requires the clearance of a 510(k) notice.

23 

On October 21, 2014, concurrent with the FDA’s publication of the reclassification of Powered Exoskeleton devices, the FDA issued the Company an “Untitled Letter” which informed us in writing of the agency’s belief that this new product classification applied to our Ekso GT device. On December 24, 2014, we filed a 510(k) notice for the Ekso robotic exoskeleton, which was accepted by the FDA for substantive review on July 29, 2015. As discussed above, we received FDA clearance to market its Ekso GT in accordance with the device’s labeling on April 4, 2016.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based upon our condensed consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses, and the related disclosure of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances. Our estimates form the basis for our judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

An accounting policy is considered to be critical if it requires an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the estimate is made, and if different estimates that reasonably could have been used, or changes in the accounting estimate that are reasonably likely to occur, could materially impact the condensed consolidated financial statements. We believe that our critical accounting policies reflect the more significant estimates and assumptions used in the preparation of the condensed consolidated financial statements.

We build medical device robotic exoskeletons for sale and capitalizes into inventory materials, direct labor, and overhead in connection with the manufacture and assembly of these units.

Adoption of New Accounting Policy

Effective January 1, 2018, we adopted ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) and the additional related amendments. We adopted the new standard using the modified retrospective transition method. The adoption did not result in a cumulative adjustment to our consolidated balance sheet as of January 1, 2018, nor did it materially impact the aggregate amount and timing of our revenue recognition subsequent to adoption. We have provided enhanced revenue recognition disclosures as required by the new standard (Refer to Note 6, Revenue Recognition in the notes to condensed consolidated financial statements, which appear under Item 1 of this Quarterly Report on Form 10-Q).

Revenue

Device and related increased $1.1 million, or 79%, for the three months ended March 31, 2018, compared to the same period of 2017. This increase was made up of a $1.2 million increase in medical device revenue, primarily due to a higher volume of medical device sales, partially offset by a $0.1 million decrease in industrial device revenue.

Gross Profit

Gross profit increased $0.4 million, or 118%, for the three months ended March 31, 2018, compared to the same period of 2017, primarily due to higher sales of medical devices.

Operating Expenses

Sales and marketing expenses increased $0.8 million, or 26%, for the three months ended March 31, 2018, compared to the same period of 2017 primarily due to severance expense of $0.2 million associated with the departure of the President of EksoWorks business unit, an increase in marketing efforts related to the commercialization of the Company’s medical devices for rehabilitation and its exoskeleton offerings for industrial applications, and an increase in clinical research activity.

25 

Research and development expenses decreased $1.1 million, or 37%, for the three months ended March 31, 2018, compared to the same period of 2017 primarily due to lower employment costs as a result of the company-wide reduction in workforce in May 2017.

General and administrative expenses increased $1.2 million, or 47%, for the three months ended March 31, 2018, compared to the same period of 2017. This was primarily due to severance of $0.4 million and additional stock-based compensation expense of $0.4 million from the modification of equity awards related to the departure of the Chief Executive Officer, and a $0.6 million increase in business development related activities in China paid for in Q3 2017.

Change in fair value, contingent liabilities for the three months ended March 31, 2018, included changes of the fair value of the contingent consideration liability related to Equipois sales earnouts and contingent success fee liability related to the outstanding debt with lender.

Other Income (Expense), Net

Gain on warrant liability of $0.7 million for the three months ended March 31, 2018 was associated with the revaluation of warrants issued in 2015, compared to a $0.1 million loss from the revaluation of warrants issued in 2015 for the three months ended March 31, 2017. The gains and losses on the revaluation of warrants are primarily driven by changes in our stock price.

Other income, net increased $0.1 million or 430% for the three months ended March 31, 2018, compared to the same period of 2017, due to unrealized gains and losses on foreign currency revaluations of monetary assets and liabilities.

Financial Condition, Liquidity and Capital Resource

Since the Company’s inception, it has devoted substantially all its efforts toward the development of exoskeletons for the medical, military and industrial markets, toward the commercialization of medical exoskeletons to rehabilitation centers and toward raising capital. Accordingly, the Company is in the early commercialization stage. The Company has financed its operations primarily through the issuance and sale of equity securities for cash consideration and convertible and promissory notes, as well as from government research grant awards and strategic collaboration payments.

Cash and Working Capital

Cash on hand at March 31, 2018 was $20.6 million compared to $27.8 million at December 31, 2017. For the three months ended March 31, 2018, the Company used $6.7 million of cash in operations compared to $7.3 million for the three months ended March 31, 2017.

Liquidity and Capital Resources

As of March 31, 2018, we had an accumulated deficit of $152.1 million.  Largely as a result of significant research and development activities related to the development of the Company’s advanced technology and commercialization of this technology into its medical device business, the Company has incurred significant operating losses and negative cash flows from operations since inception. The Company has also recognized significant non-cash losses in previous periods associated with the revaluation of certain securities, which have contributed significantly to its accumulated deficit. In the three months ended March 31, 2018, the Company used $6.7 million of cash in its operations.

Cash on hand at March 31, 2018 was $20.6 million, compared to $27.8 million at December 31, 2017. As noted in Note 9 in the notes to our condensed consolidated financial statements under the caption Long-Term Debt, borrowings under our long-term debt agreement have a requirement of minimum cash on hand roughly equivalent to three months of cash burn. As of March 31, 2018, the most recent determination of this restriction, $5.5 million of cash must remain as unrestricted, with such amounts to be re-computed at each month end period. After considering cash such restriction, effective unrestricted cash as of March 31, 2018 is estimated to be $15.0 million. Based on current forecasted amounts, our cash on hand will not be sufficient to satisfy our operations for the next twelve months from the date of issuance of these condensed consolidated financial statements, which raises substantial doubt about our ability to continue as a going concern.

Based upon the Company’s current cash resources, the recent rate of using cash for operations and investment, and assuming modest increases in current revenue offset by incremental increases in expenses related to increased sales and marketing and research and development, and a potential increase in rental activity from its medical device business, the Company believes it has sufficient resources to meet its financial obligations into the first quarter of 2019. The Company will require significant additional financing. The Company is actively pursuing opportunities to obtain additional financing in the future through public or private equity and/or debt financings, corporate collaborations, or warrant solicitations.  

26 

The Company’s actual capital requirements may vary significantly and will depend on many factors. The Company plans to continue its investments (i) in its clinical and sales initiatives to accelerate adoption of the Ekso robotic exoskeleton in the rehabilitation market, (ii) in its research, development and commercialization activities with respect to an Ekso robotic exoskeleton for home use, and/or (iii) in the development and commercialization of able-bodied exoskeletons for industrial use. Consequently, the Company may require significant additional financing in the future, which the Company intends to raise through corporate collaborations, public or private equity offerings, debt financings, or warrant solicitations. Sales of additional equity securities by us could result in the dilution of the interests of existing stockholders. There can be no assurance that financing will be available when required in sufficient amounts, on acceptable terms or at all. In the event that the necessary additional financing is not obtained, the Company may be required to further reduce its discretionary overhead costs substantially, including research and development, general and administrative, and sales and marketing expenses or otherwise curtail operations.   

Cash and Cash Equivalents

The following table summarizes the sources and uses of cash (in thousands). The Company held no cash equivalents for any of the periods presented.

Cash at the beginning of the period		27,813			16,846
Cash at the end of the period	$	20,572		$	9,426

Net Cash Used in Operating Activities

Net cash used in operations decreased $0.5 million, or 7%, for the three months ended March 31, 2018, compared to the same period of 2017 primarily due to decreased employment costs as a result of the company-wide reduction in workforce in May 2017.

Net Cash Used in Investing Activities

Net cash used in investing activities decreased $0.1 million for the three months ended March 31, 2018, compared to the same period of 2017 primarily due to the absence of capitalizable implementation cost associated with our new enterprise resource planning system which was implemented in October 2017.

Net Cash (Used in) Provided by Financing Activities

Net cash used in financing activities of $0.4 million for the three months ended March 31, 2018 was from the commencement of principal payments in the current quarter related to our term loan of $7.0 million.

Net cash generated by financing activities during the three months ended March 31, 2017 was inconsequential

In addition to the table above, which reflects only fixed payment obligations, the Company has two license agreements to maintain exclusive rights to certain patents. Under these license agreements, the Company is required to pay 1% of net sales of products sold to entities other than the U.S. government. In the event of a sublicense, the Company will owe 21% of license fees and must pass through 1% of the sub-licensee’s net sales of products sold to entities other than the U.S. government. The license agreements also stipulate minimum annual royalties of $50,000 per year.

In connection with our acquisition of Equipois in December 2015, the Company assumed the rights and obligations of Equipois under a license agreement with the developer of certain intellectual property related to mechanical balance and support arm technologies, which grants the Company an exclusive license with respect to the technology and patent rights for certain fields of use. Pursuant to the terms of the license agreement, the Company pays the developer a single-digit royalty on net receipts, subject to a $50,000 annual minimum royalty requirement.

Item 3. Quantitative and Qualitative Disclosure About Market Risk

We are exposed to market risks in the ordinary course of our business, including inflation risks.

We do not believe that inflation has had a material effect on our business, financial condition or results of operations. If our costs were to become subject to significant inflationary pressures, we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could harm our business, financial condition and results of operations.

In addition, we conduct business in foreign countries and have subsidiaries based in the United Kingdom and Germany. Accordingly, we are exposed to exchange rate risk. See Item 7A. Quantitative and Qualitative Disclosures About Market Risk in our Annual Report on Form 10-K for the year ended December 31, 2017.

Item 4. Controls and Procedures

Disclosure Controls and Procedures.

Our management, with the participation of our principal executive officer and principal financial officer, conducted an evaluation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (“Exchange Act”)) as of the end of the period covered by this report. Based upon that evaluation, our principal executive officer and principal financial officer concluded that, as of such date, our disclosure controls and procedures were effective to ensure that information required to be disclosed in reports filed by us under the Exchange Act is recorded, processed, summarized and reported within the required time periods and is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

It should be noted that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment and makes assumptions about the likelihood of future events. There can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.  Management believes that the financial statements included in this report fairly present in all material respects our financial condition, results of operations and cash flows for the periods presented.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

On March 1, 2018, a shareholder filed a derivative action in the United States District Court for the Northern District of California: Ward Rouse, derivatively on behalf of Ekso Bionics Holdings, Inc., v. Steven Sherman, Thomas Looby, Marilyn Hamilton, Howard Palefsky, Jack Peurach, Stanley Stern, Theodore Wang, and Amy Wendell (N.D. Cal.), Case No. 3:18-cv-01348-CRB (filed March 1, 2018). The action alleges that the individual defendants breached their fiduciary duties to the Company by allowing it to have a material weakness in its internal controls. The allegations appear to be based, almost entirely, on the allegations contained in two previously-filed securities class actions, Behket v. Ekso Bionics Holdings, Inc., Thomas Looby and Maximilian Scheder-Bieschin (N.D. Cal.), Case No. 3:18-cv-01726-CRB (filed Jan. 2, 2018; transferred to N.D. Cal. March 20, 2018); and Cheehy v. Ekso Bionics Holdings, Inc., Thomas Looby and Maximilian Scheder-Bieschin, (N.D. Cal.), Case no. 3:18-cv-00212-CRB (filed Jan. 10, 2018), both of which are described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2017, which was filed with the SEC on March 13, 2018. The complaint alleges state law claims for breach of fiduciary duties, unjust enrichment, abuse of control, and waste of corporate assets. The Company’s management believes that the lawsuit is without merit, and the Company plans to defend against it.

Item 1A. Risk Factors

Other than as listed below, we have not identified any material changes to the risk factors previously disclosed in Part I—Item 1A—“Risk Factors” in our Annual Report filed on Form 10-K for the fiscal year ended December 31, 2017 (the “Annual Report”). Our business, financial condition and operating results can be affected by a number of factors, whether currently known or unknown, including but not limited to those described in the Annual Report, any one or more of which could, directly or indirectly, cause our actual financial condition and operating results to vary materially from past, or from anticipated future, financial condition and operating results. Any of these factors, in whole or in part, could materially and adversely affect our business, financial condition, operating results and stock price. You should carefully consider the risks and uncertainties described below, together with all of the other information in this Quarterly Report on Form 10-Q, including the section titled “Part I—Item 2—“Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the condensed consolidated financial statements and related notes. 

Changes in our management team may adversely affect our operations.

Over the last five months, we have experienced turnover in our senior management. While we expect to engage in an orderly transition process as we integrate newly appointed officers and managers, we face a variety of risks and uncertainties relating to management transition, including diversion of management attention from business concerns, failure to retain other key personnel or loss of institutional knowledge. These risks and uncertainties could result in operational and administrative inefficiencies and added costs, which could adversely impact our results of operations, stock price and research and development of our products.

Description of Business

Ekso Bionics Holdings, Inc. (the “Company”) designs, develops and sells exoskeleton technology to augment human strength, endurance and mobility. The Company’s exoskeleton technology serves multiple markets and can be used both by able-bodied users as well as by persons with physical disabilities. The Company has sold, rented or leased devices that (a) enable individuals with neurological conditions affecting gait (stroke and spinal cord injury) to rehabilitate and to walk again and (b) allow industrial workers to perform heavy duty work for extended periods. Founded in 2005, the Company is headquartered in the Bay Area and is listed on the Nasdaq Capital Market under the symbol “EKSO”.

Liquidity and Going Concern

As of March 31, 2018, the Company had an accumulated deficit of $152,055.  Largely as a result of significant research and development activities related to the development of the Company’s advanced technology and commercialization of this technology into its medical device business, the Company has incurred significant operating losses and negative cash flows from operations since inception. The Company has also recognized significant non-cash losses in previous periods associated with the revaluation of certain securities, which have contributed significantly to its accumulated deficit. In the three months ended March 31, 2018, the Company used $6,745 of cash in its operations.

Cash on hand at March 31, 2018 was $20,572, compared to $27,813 at December 31, 2017. As noted in Note 9, Long-Term Debt, borrowings under the Company’s long-term debt agreement have a requirement of minimum cash on hand roughly equivalent to three months of cash burn. As of March 31, 2018, the most recent determination of this restriction, $5,526 of cash must remain as unrestricted, with such amounts to be re-computed at each month end period. After considering cash such restriction, effective unrestricted cash as of March 31, 2018 is estimated to be $15,046. Based on current forecasted amounts, the Company’s cash on hand will not be sufficient to satisfy the Company’s operations for the next twelve months from the date of issuance of these condensed consolidated financial statements, which raises substantial doubt about the Company’s ability to continue as a going concern.

Based upon the Company’s current cash resources, the recent rate of using cash for operations and investment, and assuming modest increases in current revenue offset by incremental increases in expenses related to increased sales and marketing and research and development, and a potential increase in rental activity from its medical device business, the Company believes it has sufficient resources to meet its financial obligations into the first quarter of 2019. The Company will require significant additional financing. The Company is actively pursuing opportunities to obtain additional financing in the future through public or private equity and/or debt financings, corporate collaborations, or warrant solicitations.

The Company’s actual capital requirements may vary significantly and will depend on many factors. The Company plans to continue its investments (i) in its clinical and sales initiatives to accelerate adoption of the Ekso robotic exoskeleton in the rehabilitation market, (ii) in its research, development and commercialization activities with respect to an Ekso robotic exoskeleton for home use, and/or (iii) in the development and commercialization of able-bodied exoskeletons for industrial use. Consequently, the Company may require significant additional financing in the future, which the Company intends to raise through corporate collaborations, public or private equity offerings, debt financings, or warrant solicitations. Sales of additional equity securities by the Company could result in the dilution of the interests of existing stockholders. There can be no assurance that financing will be available when required in sufficient amounts, on acceptable terms or at all. In the event that the necessary additional financing is not obtained, the Company may be required to further reduce its discretionary overhead costs substantially, including research and development, general and administrative, and sales and marketing expenses or otherwise curtail operations.

Basis of Presentation and Summary of Significant Accounting Policies and Estimates

Accounting Policies [Abstract]

Summary of Significant Accounting Policies and Estimates

2. Basis of Presentation and Summary of Significant Accounting Policies and Estimates

Basis of Presentation

In the opinion of management, the accompanying unaudited condensed consolidated financial statements have been prepared on a consistent basis with the audited consolidated financial statements for the fiscal year ended December 31, 2017, and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state the information set forth herein. The condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) and therefore, omit certain information and footnote disclosure necessary to present the financial statements in accordance with generally accepted accounting principles in the United States (“GAAP”). These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017, which was filed with the SEC on March 13, 2018. The results of operations for the three months ended March 31, 2018 are not necessarily indicative of the results to be expected for the entire fiscal year or any future periods.

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the balance sheet, and the reported amounts of revenues and expenses during the reporting period. For the Company, these estimates include, but are not limited to: revenue recognition, deferred revenue and the deferral of the associated costs, future warranty costs, maintenance and planned improvement costs associated with medical device units sold prior to 2016, useful lives assigned to long-lived assets, realizability of deferred tax assets, the valuation of options and warrants, and contingencies. Actual results could differ from those estimates.

Inventory

Inventories are recorded at the lower of cost or net realizable value. Cost is determined using the standard cost method. Parts from vendors are received and recorded as raw material. Once the raw materials are incorporated in the fabrication of the product, the related value of the component is recorded as work in progress (“WIP”). Direct labor and manufacturing overhead costs are also allocated and recorded to WIP inventory. Finished goods are comprised of completed products that are ready for customer shipment. The Company periodically evaluates the carrying value of inventory on hand for potential excess amounts over sales and forecasted demand. Excess and obsolete inventories identified, if any, are recorded as an inventory impairment charge to the consolidated statements of operations and comprehensive loss. The Company’s estimate of write downs for excess and obsolete inventory is based on a detailed analysis of on-hand inventory and purchase commitments in excess of forecasted demand.  Subsequent disposals of inventories are recorded as a reduction of an inventory reserve.

Revenue Recognition

Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company enters into contracts that can include various combinations of products and services, which when capable of being distinct, are accounted for as separate performance obligations.

Nature of Products and Services

The Company’s medical device segment revenue is generated through the sales of the Ekso GT, associated software (SmartAssist, VariableAssist), accessories, and support and maintenance contracts (Ekso Care). Revenue from medical device product sales is recognized at the point in time when control of the product transfers to the customer. Transfer of control generally occurs upon shipment from the Company’s facility for sales of the Ekso GT, software and accessories. Ekso Care support and maintenance contracts extend coverage beyond the Company’s standard warranty agreements. The separately priced Ekso Care contracts range from 12 to 48 months. The Company receives payment at the inception of the contract and recognize revenue over the term of the agreement.

The Company’s industrial device segment revenue is generated by the sales of the support arm (EksoZeroG) and the upper body exoskeleton (EksoVest). Revenue from industrial device sales is recognized at the point in time when control of the product transfers to the customer. Transfer of control generally occurs upon shipment from the Company’s facility for sales of the EksoZeroG and EksoVest.

The Company’s engineering services segment revenue is generated by collaborative arrangements or government grants. Cost reimbursements or grant revenue are recognized over the life of the contract in proportion to the costs incurred in satisfying the obligations under the contract.  

Refer to Note 6 – Revenue Recognition for further information, including revenue disaggregated by source.

Going Concern

The Company assesses its ability to continue as a going concern at every interim and annual period in accordance with Accounting Standards Codification 205-40. The accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern.

Concentration of Credit Risk and Other Risks and Uncertainties

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and accounts receivable. The Company maintains its cash accounts in excess of federally insured limits. However, the Company believes it is not exposed to significant credit risk due to the financial position of the depository institutions in which these deposits are held. The Company extends credit to customers in the normal course of business and performs ongoing credit evaluations of its customers. Concentrations of credit risk with respect to accounts receivable exist to the full extent of amounts presented in the consolidated financial statements. The Company does not require collateral from its customers to secure accounts receivable.

Accounts receivable are derived from the sale of products shipped to and services performed for customers. Invoices are aged based on contractual terms with the customer. The Company reviews accounts receivable for collectability and records an allowance for credit losses, as needed. The Company has not experienced any material losses related to accounts receivable as of March 31, 2018 and December 31, 2017.

Many of the sales contracts with customers outside of the U.S. are settled in a foreign currency. The Company does not enter into any foreign currency hedging agreements and is susceptible to gains and losses from foreign currency fluctuations. To date, the Company has not experienced significant gains or losses upon settling foreign currency denominated accounts receivable.

As of March 31, 2018, the Company had one customer with an accounts receivable balance totaling 10% or more of the Company’s total accounts receivable (15%) compared with one customer as of December 31, 2017 (10%).

In the three months ended March 31, 2018, the Company had one customer with sales of 10% or more of the Company’s total revenue (11%), compared with one customer in the three months ended March 31, 2017 (26%).

Recent Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) which will require lessees to recognize assets and liabilities for leases with lease terms of more than 12 months. For finance leases, a lessee is required to: (1) recognize a right-of-use asset and a lease liability, initially measured at  the present value of the lease payments, in the statement of financial position, (2) recognize interest on the lease liability separately from amortization of the right-of-use asset in the statement of comprehensive income, and (3) classify repayments of the principal portion of the lease liability within financing activities and payments of interest on the lease liability and variable lease payments within operating activities in the statement of cash flows. For operating leases, a lessee is required to: (1) recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position, (2) recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a generally straight-line basis, and (3) classify all cash payments within operating activities in the statement of cash flows. The new guidance is effective for fiscal years beginning after December 15, 2018.  The Company is evaluating the impact that ASU 2016-02 will have on its consolidated financial statements and related disclosures.

In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment.  ASU 2017-04 eliminated the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities are required to record an impairment charge based on the excess of the carrying amount over its fair value. The new standard will be effective for the Company beginning January 1, 2020 and early adoption is permitted. The Company does not expect the impact of adopting ASU 2017-04 to be material on its consolidated financial statements.

Recently Adopted Accounting Standards

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). The updated standard will replace most existing revenue recognition guidance in U.S. GAAP. The new standard introduces a five-step process to be followed in determining the amount and timing of revenue recognition. It also provides guidance on accounting for costs incurred to obtain or fulfill contracts with customers, and establishes disclosure requirements which are more extensive than those required under prior U.S. GAAP. The FASB has issued numerous amendments to ASU 2014-09 from August 2015 through January 2018, which provide supplemental and clarifying guidance, as well as amend the effective date of the new standard. ASU 2014-09, as amended, is effective for the Company in the first quarter of 2018. The standard permits the use of either the retrospective or modified retrospective (cumulative effect) transition method. Effective January 1, 2018, the Company adopted the new standard using the modified retrospective transition method. The adoption did not result in a cumulative adjustment to the Company’s consolidated balance sheet as of January 1, 2018, nor did it materially impact the aggregate amount and timing of the Company’s revenue recognition subsequent to adoption. The Company has provided enhanced revenue recognition disclosures as required by the new standard (Refer to Note 6, Revenue Recognition).

Fair Value Measurements

4. Fair Value Measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Three levels of inputs, of which the first two are considered observable and the last unobservable, may be used to measure fair value which are the following:

• Level 1—Quoted prices in active markets for identical assets or liabilities. The Company considers a market to be active when transactions for the asset occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

• Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

• Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The valuation of Level 3 investments requires the use of significant management judgments or estimation.

The Company’s fair value hierarchies for its financial assets and liabilities which require fair value measurement are as follows:

	Total		Level 1		Level 2		Level 3
March 31, 2018
Liabilities
Warrant liabilities	$	916	$	-	$	-	$	916

The following table sets forth a summary of the changes in the fair value of the Company’s Level 3 financial liabilities for the three months ended March 31, 2018, which were measured at fair value on a recurring basis:

Revenue Recognition Disclosure [Abstract]

Revenue Recognition Disclosure

6. Revenue Recognition

Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company enters into contracts that can include various combinations of products and services, which when capable of being distinct, are accounted for as separate performance obligations. Revenue recognition is evaluated based on the following five steps: (i) identification of the contract with the customer; (ii) identification of the performance obligations in the contract; (iii) determination of the transaction price; (iv) allocation of the transaction price to the performance obligations in the contract; and (v) recognition of revenue when or as a performance obligation is satisfied.

For multiple-element arrangements, revenue is allocated to each performance obligation based on its relative standalone selling price. Standalone selling prices are determined based on observable prices at which the Company separately sells its products or services. If a standalone selling price is not directly observable, the Company estimates the selling price based on market conditions and entity-specific factors including features and functionality of the product and/or services, the geography of our customers, type of the Company’s markets. Any discounts or other reductions to the transaction price are allocated proportionately to all performance obligations within the multiple-element arrangement.

Contract Balances

Timing of revenue recognition may differ from the timing of invoicing to customers and receipt of payment. For the sale of its products, the Company generally recognizes revenue at a point in time through the ship-and-bill performance obligations. For service agreements, the Company generally invoices customers at the beginning of the coverage period and record revenue related to the billed amounts over time, equivalent to the coverage period of the maintenance and support contract.

Deferred revenue is comprised mainly of unearned revenue related to extended support and maintenance contracts (Ekso Care) but also includes other offerings for which the Company has been paid in advance and earn revenue when the Company transfers control of the product or service.

Deferred revenues consisted of the following:

	March 31,		December 31,
	2018		2017
Deferred extended maintenance and support	$	1,903	$	1,763
Deferred rental income		71		73
Customer deposits and advances		49		52
Deferred medical device revenues		35		31
Total deferred revenues		2,058		1,919
Less current portion		(1,292)		(1,103)
Deferred revenues, non-current	$	766	$	816

Deferred revenue activity consisted of the following:

	Three months ended
	March 31, 2018
Beginning balance	$	1,919
Deferral of revenue		703
Recognition of deferred revenue		(564)
Ending balance	$	2,058

At March 31, 2018, our deferred revenue, was $2,058 . Excluding customer deposits, we expect to recognize approximately $712 of the deferred revenue in the remainder of 2018, $543 in 2019, and $754 thereafter.

As of March 31, 2018, and December 31, 2017, accounts receivable, net of allowance for doubtful accounts, were $3,574 and $2,760, respectively, and are included in current assets on the Company’s consolidated balance sheets.

The allowance for doubtful accounts reflects the Company’s best estimate of probable losses inherent in the accounts receivable balance. The Company determines the allowance based on known troubled accounts, historical experience, and other currently available evidence. Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 to 60 days.

Long-Term Debt

9. Long-Term Debt

In December 2016,  the Company entered into a loan agreement and received $7,000 that bears interest on the outstanding daily balance at a floating per annum rate equal to the 30-day U.S. LIBOR plus 5.41%. The loan agreement created a first priority security interest with respect to substantially all assets of the Company, including proceeds of intellectual property, but expressly excluding intellectual property itself.

 

The Company was required to pay accrued interest on the current loan on the first day of each month through and including January 1, 2018. Commencing on February 1, 2018, the Company is required to make equal monthly payments of principal, together with accrued and unpaid interest. The principal balance of the current loan amortizes ratably over 36 months, and matures on January 1, 2021, at which time all unpaid principal and accrued and unpaid interest shall be due and payable in full. In addition, a final payment of $245 will be due on the maturity date, of which $120 has accreted as of March 31, 2018, to be paid in 2021 and is included as a component of note payable on the Company’s condensed consolidated balance sheets.

 

In December 2016, and pursuant to the loan agreement, the Company entered into a success fee agreement with the lender under which the Company agreed to pay the lender a $250 success fee upon the first to occur of any of the following events: (a) a sale or other disposition by the Company of all or substantially all of its assets; (b) a merger or consolidation of the Company into or with another person or entity, where the holders of the Company’s outstanding voting equity securities immediately prior to such merger or consolidation hold less than a majority of the issued and outstanding voting equity securities of the successor or surviving person or entity immediately following the consummation of such merger or consolidation; or (c) the closing price per share for the Company’s common stock being $8.00 or more for five successive business days. The estimated fair value of the success fee was determined using the Binomial Lattice Model and was recorded as a discount to the debt obligation. The fair value of the contingent success fee is re-measured each reporting period with any adjustments in fair value being recognized in the consolidated statements of operations and comprehensive loss. The success fee is classified as a liability on the condensed consolidated balance sheets. At March 31, 2018, the fair value of the contingent success fee liability was $40.

 

The loan agreement includes a liquidity covenant requiring that the Company maintain unrestricted cash and cash equivalents in accounts of the lender or subject to control agreements in favor of the lender in an amount equal to at least three months of “Monthly Cash Burn,” which is the Company’s average monthly net income (loss) for the trailing six-month period plus certain expenses and plus the average monthly principal due and payable on interest-bearing liabilities in the immediately succeeding three-month period. Such amount was determined to be $5,526 as of March 31, 2018, the most current determination, with the amount subject to change on a month-to-month basis. At March 31, 2018, with cash on hand of $20,572, the Company was compliant with this liquidity covenant and all other covenants.

 

The final payment fee, debt issuance costs, and the initial fair value of the success fee combined with the stated interest resulted in an effective interest rate of 9.67% for the three months ended March 31, 2018. The final payment fee, initial fair value of the success fee and debt issuance costs was and will be accreted, amortized and amortized, respectively, to interest expense using the effective interest method over the life of the loan.

 

The following table presents scheduled principal payments of our long-term debt and final payment fee as of March 31, 2018:

Capitalization and Equity Structure

11. Capitalization and Equity Structure

Summary

The Company’s authorized capital stock at March 31, 2018 consisted of 141,429 shares of common stock and 10,000 shares of preferred stock. At March 31, 2018, 60,355 shares of common stock were issued and outstanding and no shares of preferred stock were issued and outstanding.

On October 30, 2017, the Board approved an amendment to the Company’s Articles of Incorporation to increase the number of shares of our common stock by 70,000 shares to 141,429 shares (the “Authorized Capital Amendment”), subject to the approval of such amendment by the stockholders. On December 21, 2017, a special meeting of the stockholders was convened (the “December Special Meeting”). In the definitive proxy statement dated November 24, 2017 filed by the Company with the SEC in respect of the December Special Meeting (the “November Proxy Statement”), the Board solicited the vote of the stockholders in favor of the Authorized Capital Amendment. The November Proxy Statement stated that broker non-votes in respect of the Authorized Capital Amendment would be counted as votes against the amendment. However, under relevant stock exchange rules, brokers had the discretionary authority to vote any shares held in their name on behalf of a beneficial owner (“Broker Shares”), and in respect of which the broker did not receive voting instruction from the beneficial owner, in favor of the Authorized Capital Amendment. As such, brokers voted approximately 17,628 Broker Shares, in respect of which the brokers had not received voting instructions from the beneficial owners of such shares, in favor of the Authorized Capital Amendment at the December Special Meeting. Accordingly, after taking into account such Broker Shares, the Authorized Capital Amendment was approved by the stockholders at the December Special Meeting. However, as disclosed in more detail under Item 3 in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, some stockholders of the Company have claimed that the disclosure in the November Proxy Statement in connection with the effect on the Authorized Capital Amendment of beneficial owners not providing voting instructions in respect of their Broker Shares was incorrect. Accordingly, management has solicited stockholders to ratify the Authorized Capital Amendment at our 2018 Annual Meeting of Shareholders, which will be held on June 7, 2018 (the “2018 Annual Meeting”). Further information about such vote was provided in the Company’s Definitive Proxy Statement relating to its 2018 Annual Meeting of Shareholders, which was filed with the SEC on April 30, 2018 (the “2018 Proxy Statement”).

Information Agent Warrants

In September 2017, in connection with the Rights Offering in August of 2017, the Company issued warrants to purchase 200 shares of the Company’s common stock with an exercise price of $1.50 to an information agent (the “Information Agent Warrants”). The Information Agent Warrants became exercisable immediately upon issuance. These warrants were recorded in stockholders’ equity on the Company’s condensed consolidated balance sheet.

 

2015 Warrants

In December 2015, the Company issued warrants to purchase 2,122 shares with an exercise price of $3.74 per share (the “2015 Warrants”). The 2015 Warrants contain a put-option provision. Under this provision, while the 2015 Warrants are outstanding, if the Company enters into a Fundamental Transaction, defined as a merger, consolidation or similar transaction, the Company or any successor entity will, at the option of each warrant holder, exercisable at any time within 30 days after the consummation of the Fundamental Transaction, purchase the warrant from the holder exercising such option by paying to the holder an amount of cash equal to the Black-Scholes value of the remaining unexercised portion of such holder’s warrant on the date of the consummation of the Fundamental Transaction. Because of this put-option provision, the 2015 Warrants are classified as a liability and are marked to market at each reporting date.

 

The warrant liability related to the 2015 Warrants is measured at fair value at each reporting date using certain estimated inputs, which are classified within Level 3 of the fair value hierarchy. The following assumptions were used in the Black Scholes Option Pricing Model to measure the fair value of the 2015 warrants as of March 31, 2018:

Current share price	$	1.58
Conversion price	$	3.74

In June 2017, the Company’s stockholders approved an amendment of the Company’s Amended and Restated 2014 Equity Incentive Plan (the “2014 Plan”) to increase the number of shares available for grant by 1,000 shares.  The total shares authorized for grant under the 2014 Plan is 4,714.

 

On October 30, 2017, the Board approved an amendment to the 2014 Plan to increase the maximum number of shares of common stock that may be issued under the 2014 Plan by 4,400 shares, from 4,714 to 9,114 shares (the “2014 Plan Amendment”) effective as of the time such amendment is approved by the stockholders. At the December Special Meeting, a proposal was submitted to be voted on by the stockholders to approve the 2014 Plan Amendment contingent on the approval by the stockholders of the Authorized Capital Amendment. The proposal was approved by the stockholders at the December Special Meeting, with approximately 25,205 shares voted for, 2,955 shares voted against, and 356 shares abstaining. However, since the proposal was contingent on the approval by the stockholders of the Authorized Capital Amendment, management has solicited stockholders to ratify the 2014 Plan Amendment at the 2018 Annual Meeting. Further information is provided in the 2018 Proxy Statement.

As of March 31, 2018, there were 5,162 shares available for future awards after taking into account the 2014 Plan Amendment.

As of March 31, 2018, total unrecognized compensation cost related to unvested stock options was $1,809. This amount is expected to be recognized as stock-based compensation expense in the Company’s condensed consolidated statements of operations and comprehensive income over the remaining weighted average vesting period of 2.29 years.

 

The per-share fair value of each stock option was determined on the date of grant using the Black-Scholes option pricing model using the following assumptions:

	Three months ended March 31,
	2018			2017
Dividend yield		—			—
Risk-free interest rate		2.74	%		2.05% - 2.40	%
Expected term (in years)		10			6-10
Volatility		88	%		80%-82	%

Restricted Stock Units

Beginning in 2017, the Company issued restricted stock units (“RSUs”), to employees and non-employees as permitted by the 2014 Plan. Each restricted stock unit corresponds to one share of the Company’s common stock and becomes issuable upon vesting. The fair value of restricted stock units is determined based on the closing price of the Company’s common stock on the date of grant.

RSU activity for the three months ended March 31, 2018 is summarized below:

	Number of Shares		Weighted- Average Grant Date Fair Value
Unvested as of January 1, 2018		617	$	1.65

401(k) Plan Share Match

In August 2017, the Company’s Board of Directors approved a match benefit to the Ekso Bionics 401(k) plan (the “401(k) Plan”) in the form of shares of the Company’s common stock. The Company will make a matching contribution to the 401(k) Plan in an amount equal to 100% of each eligible employee’s elected deferral (up to the statutory limit) for the year ending December 31, 2017 and equal to 50% of each employee’s elected deferral for each year thereafter.

 

During the three months ended March 31, 2018, the Company issued 221 shares of common stock to each eligible employee’s deferral account for the 401(k) Plan matching contribution for the year ended December 31, 2017.

Material Contracts

The Company enters various license, research collaboration and development agreements which provide for payments to the Company for government grants, fees, cost reimbursements typically with a markup, technology transfer and license fees, and royalty payments on sales.

The Company has two license agreements with the Regents of the University of California to maintain exclusive rights to certain patents. Pursuant to those license agreements, the Company is required to pay 1% of net sales of products sold to entities other than the U.S. government and, in the event of a sub-license, the Company will owe 21% of license fees and must pass through 1% of the sub-licensee’s net sales of products sold to entities other than the U.S. government. The agreements also stipulate minimum annual royalties of $50.

In connection with acquisition of Equipois, the Company assumed the rights and obligations of Equipois under a license agreement with the developer of certain intellectual property related to mechanical balance and support arm technologies, which grants the Company an exclusive license with respect to the technology and patent rights for certain fields of use. Pursuant to the terms of the license agreement, the Company pays the developer a single-digit royalty on net receipts, subject to a $50 annual minimum royalty requirement.

Contingencies

In the normal course of business, the Company is subject to various legal matters. In the opinion of management, the resolution of such matters will not have a material adverse effect on the Company’s condensed consolidated financial statements.

Segment Reporting [Abstract]

Segment Disclosures

16. Segment Disclosures

The Company has three reportable segments: Medical Devices, Industrial Sales, and Engineering Services. The Medical Devices segment designs and engineers technology for, and commercializes, manufactures, and sells exoskeletons for applications in the medical markets. The Industrial Sales segment designs, engineers, commercializes, manufactures, and sells exoskeleton devices to allow able-bodied users to perform heavy duty work for extended periods. Engineering Services generates revenue principally from collaborative research and development service arrangements, technology license agreements, and government grants where the Company uses its robotics domain knowledge in bionic exoskeletons to bid on and procure contracts and grants from entities such as the National Science Foundation and the Defense Advanced Research Projects Agency.

The Company evaluates performance and allocates resources based on segment gross profit margin. The reportable segments are each managed separately because they serve distinct markets, and one segment provides a service and the others manufacture and distribute unique products. The Company does not consider net assets as a segment measure and, accordingly, assets are not allocated.

Basis of Presentation and Summary of Significant Accounting Policies and Estimates (Policies)

3 Months Ended

Mar. 31, 2018

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

In the opinion of management, the accompanying unaudited condensed consolidated financial statements have been prepared on a consistent basis with the audited consolidated financial statements for the fiscal year ended December 31, 2017, and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state the information set forth herein. The condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”) and therefore, omit certain information and footnote disclosure necessary to present the financial statements in accordance with generally accepted accounting principles in the United States (“GAAP”). These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017, which was filed with the SEC on March 13, 2018. The results of operations for the three months ended March 31, 2018 are not necessarily indicative of the results to be expected for the entire fiscal year or any future periods.

Use of Estimates

Use of Estimates

The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the balance sheet, and the reported amounts of revenues and expenses during the reporting period. For the Company, these estimates include, but are not limited to: revenue recognition, deferred revenue and the deferral of the associated costs, future warranty costs, maintenance and planned improvement costs associated with medical device units sold prior to 2016, useful lives assigned to long-lived assets, realizability of deferred tax assets, the valuation of options and warrants, and contingencies. Actual results could differ from those estimates.

Inventory

Inventory

Inventories are recorded at the lower of cost or net realizable value. Cost is determined using the standard cost method. Parts from vendors are received and recorded as raw material. Once the raw materials are incorporated in the fabrication of the product, the related value of the component is recorded as work in progress (“WIP”). Direct labor and manufacturing overhead costs are also allocated and recorded to WIP inventory. Finished goods are comprised of completed products that are ready for customer shipment. The Company periodically evaluates the carrying value of inventory on hand for potential excess amounts over sales and forecasted demand. Excess and obsolete inventories identified, if any, are recorded as an inventory impairment charge to the consolidated statements of operations and comprehensive loss. The Company’s estimate of write downs for excess and obsolete inventory is based on a detailed analysis of on-hand inventory and purchase commitments in excess of forecasted demand.  Subsequent disposals of inventories are recorded as a reduction of an inventory reserve.

Revenue Recognition

Revenue Recognition

Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company enters into contracts that can include various combinations of products and services, which when capable of being distinct, are accounted for as separate performance obligations.

Nature of Products and Services

The Company’s medical device segment revenue is generated through the sales of the Ekso GT, associated software (SmartAssist, VariableAssist), accessories, and support and maintenance contracts (Ekso Care). Revenue from medical device product sales is recognized at the point in time when control of the product transfers to the customer. Transfer of control generally occurs upon shipment from the Company’s facility for sales of the Ekso GT, software and accessories. Ekso Care support and maintenance contracts extend coverage beyond the Company’s standard warranty agreements. The separately priced Ekso Care contracts range from 12 to 48 months. The Company receives payment at the inception of the contract and recognize revenue over the term of the agreement.

The Company’s industrial device segment revenue is generated by the sales of the support arm (EksoZeroG) and the upper body exoskeleton (EksoVest). Revenue from industrial device sales is recognized at the point in time when control of the product transfers to the customer. Transfer of control generally occurs upon shipment from the Company’s facility for sales of the EksoZeroG and EksoVest.

The Company’s engineering services segment revenue is generated by collaborative arrangements or government grants. Cost reimbursements or grant revenue are recognized over the life of the contract in proportion to the costs incurred in satisfying the obligations under the contract.  

Refer to Note 6 – Revenue Recognition for further information, including revenue disaggregated by source.

Going Concern

Going Concern

The Company assesses its ability to continue as a going concern at every interim and annual period in accordance with Accounting Standards Codification 205-40. The accompanying condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern.

Concentration of Credit Risk and Other Risks and Uncertainties

Concentration of Credit Risk and Other Risks and Uncertainties

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and accounts receivable. The Company maintains its cash accounts in excess of federally insured limits. However, the Company believes it is not exposed to significant credit risk due to the financial position of the depository institutions in which these deposits are held. The Company extends credit to customers in the normal course of business and performs ongoing credit evaluations of its customers. Concentrations of credit risk with respect to accounts receivable exist to the full extent of amounts presented in the consolidated financial statements. The Company does not require collateral from its customers to secure accounts receivable.

Accounts receivable are derived from the sale of products shipped to and services performed for customers. Invoices are aged based on contractual terms with the customer. The Company reviews accounts receivable for collectability and records an allowance for credit losses, as needed. The Company has not experienced any material losses related to accounts receivable as of March 31, 2018 and December 31, 2017.

Many of the sales contracts with customers outside of the U.S. are settled in a foreign currency. The Company does not enter into any foreign currency hedging agreements and is susceptible to gains and losses from foreign currency fluctuations. To date, the Company has not experienced significant gains or losses upon settling foreign currency denominated accounts receivable.

As of March 31, 2018, the Company had one customer with an accounts receivable balance totaling 10% or more of the Company’s total accounts receivable (15%) compared with one customer as of December 31, 2017 (10%).

In the three months ended March 31, 2018, the Company had one customer with sales of 10% or more of the Company’s total revenue (11%), compared with one customer in the three months ended March 31, 2017 (26%).

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842) which will require lessees to recognize assets and liabilities for leases with lease terms of more than 12 months. For finance leases, a lessee is required to: (1) recognize a right-of-use asset and a lease liability, initially measured at  the present value of the lease payments, in the statement of financial position, (2) recognize interest on the lease liability separately from amortization of the right-of-use asset in the statement of comprehensive income, and (3) classify repayments of the principal portion of the lease liability within financing activities and payments of interest on the lease liability and variable lease payments within operating activities in the statement of cash flows. For operating leases, a lessee is required to: (1) recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the statement of financial position, (2) recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term on a generally straight-line basis, and (3) classify all cash payments within operating activities in the statement of cash flows. The new guidance is effective for fiscal years beginning after December 15, 2018.  The Company is evaluating the impact that ASU 2016-02 will have on its consolidated financial statements and related disclosures.

In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment.  ASU 2017-04 eliminated the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities are required to record an impairment charge based on the excess of the carrying amount over its fair value. The new standard will be effective for the Company beginning January 1, 2020 and early adoption is permitted. The Company does not expect the impact of adopting ASU 2017-04 to be material on its consolidated financial statements.

Recently Adopted Accounting Standards

Recently Adopted Accounting Standards

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). The updated standard will replace most existing revenue recognition guidance in U.S. GAAP. The new standard introduces a five-step process to be followed in determining the amount and timing of revenue recognition. It also provides guidance on accounting for costs incurred to obtain or fulfill contracts with customers, and establishes disclosure requirements which are more extensive than those required under prior U.S. GAAP. The FASB has issued numerous amendments to ASU 2014-09 from August 2015 through January 2018, which provide supplemental and clarifying guidance, as well as amend the effective date of the new standard. ASU 2014-09, as amended, is effective for the Company in the first quarter of 2018. The standard permits the use of either the retrospective or modified retrospective (cumulative effect) transition method. Effective January 1, 2018, the Company adopted the new standard using the modified retrospective transition method. The adoption did not result in a cumulative adjustment to the Company’s consolidated balance sheet as of January 1, 2018, nor did it materially impact the aggregate amount and timing of the Company’s revenue recognition subsequent to adoption. The Company has provided enhanced revenue recognition disclosures as required by the new standard (Refer to Note 6, Revenue Recognition).

Stock Issued During Period, Reverse Stock Splits, Description	On October 30, 2017, the Board approved an amendment to the Company’s Articles of Incorporation to increase the number of shares of our common stock by 70,000 shares to 141,429 shares (the “Authorized Capital Amendment”), subject to the approval of such amendment by the stockholders. On December 21, 2017, a special meeting of the stockholders was convened (the “December Special Meeting”). In the definitive proxy statement dated November 24, 2017 filed by us with the SEC in respect of the December Special Meeting (the “November Proxy Statement”), the Board solicited the vote of the stockholders in favor of the Authorized Capital Amendment. The November Proxy Statement stated that broker non-votes in respect of the Authorized Capital Amendment would be counted as votes against the amendment. However, under relevant stock exchange rules, brokers had the discretionary authority to vote any shares held in their name on behalf of a beneficial owner (“Broker Shares”), and in respect of which the broker did not receive voting instruction from the beneficial owner, in favor of the Authorized Capital Amendment. As such, brokers voted approximately 17,628 Broker Shares, in respect of which the brokers had not received voting instructions from the beneficial owners of such shares, in favor of the Authorized Capital Amendment at the December Special Meeting. Accordingly, after taking into account such Broker Shares, the Authorized Capital Amendment was approved by the stockholders at the December Special Meeting. However, as disclosed in more detail under Item 3 in the Company’s Annual Report on Form 10-K for the year ended December 31, 2017, some stockholders of the Company have claimed that the disclosure in the November Proxy Statement in connection with the effect on the Authorized Capital Amendment of beneficial owners not providing voting instructions in respect of their Broker Shares was incorrect. Accordingly, stockholders have been asked to vote again on the Authorized Capital Amendment at our 2018 Annual Meeting of Shareholders. Further information about such vote was provided in the Company’s Proxy Statement relating to its 2018 Annual Meeting of Shareholders, which was filed with the SEC on April 19, 2018.
