NEXPLANAR CORPORATION

Financial Statements

As of and for the year ended December 31, 2014

(With Independent Auditors' Report Thereon)

Independent Auditors' Report

The Board of Directors
NexPlanar Corporation:

We have audited the accompanying financial statements of NexPlanar Corporation, which comprise the balance sheet as of December 31, 2014, and the related statements of operations, stockholders' equity, and cash flows for the year then ended, and the related notes to the financial statements.

Management's Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of these financial statements in accordance with U.S. generally accepted accounting principles; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error.

Auditors' Responsibility

Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditors' judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity's preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity's internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of NexPlanar Corporation as of December 31, 2014, and the results of its operations and its cash flows for the year then ended, in accordance with U.S. generally accepted accounting principles.

(1)	Summary of Significant Accounting Policies

(a)	Description of Business

NexPlanar Corporation, or NexPlanar (the Company), is a privately owned corporation, originally organized March 21, 2003 in the state of Oregon as Neopad, Inc. NexPlanar is principally involved in the development of polyurethane pads that are used in manufacturing silicon integrated circuit wafers. These polishing pads are a consumable item used in a segment of the fabrication process called chemical mechanical planarization, or CMP.

(b)	Basis of Presentation

The Company prepares its financial statements in accordance with U.S. generally accepted accounting principles.

(c)	Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles 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 financial statements, and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

(d)	Revenue Recognition

The Company recognizes revenue when products are shipped and the customer takes ownership and assumes risk of loss, collection of the relevant receivable is probable, persuasive evidence of an arrangement exists, and the sales price is fixed or determinable.

Sales taxes collected from customers and remitted to governmental authorities are accounted for on a net basis and, therefore, are excluded from revenue in the consolidated statements of income.

(e)	Cash and Cash Equivalents

The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Cash and cash equivalents consist of cash on hand and funds in sweep account deposits.

The Company elected to invest its surplus cash into income‑earning sweep accounts on a daily basis in accordance with a policy objective that seeks to ensure both liquidity and safety of principal. The deposits into sweep accounts are not insured by the Federal Deposit Insurance Corporation.

(f)	Trade Accounts Receivable

Trade accounts receivable are recorded at the invoiced amount and do not bear interest. Amounts collected on trade accounts receivable are included in cash flows from operating activities in the statements of cash flows. The Company reviews its accounts receivable balance monthly to determine if an allowance for doubtful accounts is necessary. In assessing the necessity of an allowance, management considers historical and current market conditions, the customers' financial condition, and the current receivables aging and payment patterns. The Company did not record an allowance for doubtful accounts at December 31, 2014.

 

(g)	Inventories

Inventories are valued at standard costs, which approximate the lower of cost (weighted average) or market. Inventories at December 31, 2014 consisted of the following:

		2014
Raw materials		$	1,085
Finished goods			23
Total inventories		$	1,108

(h)	Property, Plant, and Equipment

Property, plant, and equipment are recorded at cost. Depreciation on plant and equipment is calculated on the straight‑line method over the estimated useful lives of the assets. The estimated life of computer equipment and software, machinery and equipment, and office furniture is two, five, and five years, respectively. Leasehold improvements are depreciated over the remaining term of the underlying lease. Repair and maintenance costs are expensed as incurred.

(i)	Income Taxes

The Company accounts for income taxes under the asset‑and‑liability method. Deferred tax assets and liabilities are determined based on the temporary differences between the financial statements and tax basis of assets and liabilities as measured by the enacted tax rates for the years in which the taxes are expected to be paid.

(j)	Concentration of Credit Risk

Three customers accounted for approximately 60% of total revenue for the year ended December 31, 2014. Five customers accounted for approximately 73% of total trade accounts receivable balance at December 31, 2014.  Two of these customers are related parties (note 7).

(k)	Stock Option Plan

The Company recognizes all employee share‑based compensation as a cost in the financial statements. Equity‑classified awards are measured at the grant‑date fair value of the award. The Company estimates grant‑date fair value using the Black‑Scholes option‑pricing model.

Share‑based compensation cost totaled $223 thousand for the year ended December 31, 2014, of which $46 was recorded as cost of goods sold, $14 as research and development, $39 as selling and marketing, and $124 as general and administrative, respectively.

(l)	Research and Development

The Company expenses all research and development costs as incurred. These expenses include the costs of proprietary research and development efforts as well as costs incurred in connection with third‑party collaboration efforts. Expenses incurred through proprietary research and development efforts include salaries, employee benefits, stock‑based compensation, and other headcount‑related costs, prototype development costs, contract and other outside service fees, patent strategy and filing fees, and facilities and overhead costs. Costs incurred to support third‑party collaboration efforts include membership in an industry‑specific research center, test materials, and prototype products used in experimental testing.

 

(m)	Long‑Lived Assets

Long‑lived assets, such as property, plant, and equipment, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long‑lived asset or asset group be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by that asset or asset group to its carrying value. If the carrying value of the long‑lived asset or asset group is not recoverable on an undiscounted cash flow basis, an impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values, and third‑party independent appraisals, depending on the nature of the asset. To date, no such impairments have occurred.

(n)	Fair Value of Financial Instruments

The fair value of financial instruments is the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. The carrying amounts reflected in the balance sheets for cash and cash equivalents, trade receivables, and accounts payable approximate fair value because of the short maturity for these instruments. Additionally, the Company's long‑term borrowings are at a variable interest rate that adjusts based on current market indices and as such, the recorded value approximates fair value.

(o)	Comprehensive Loss

Comprehensive loss is equal to net loss for the year ended December 31, 2014. As such, no separate statements of comprehensive loss have been presented.

(2)	Property and Equipment

Property and equipment consist of the following:

		2014
Computer equipment and software		$	211
Manufacturing equipment			6,213
Office furniture			72
Leasehold improvements			1,412
Leasehold improvements under capital lease (note 3)			518
Construction in progress			86
			8,512
Less accumulated depreciation			(4,788	)
		$	3,724

Total depreciation expense for the year ended December 31, 2014 was $1,092.

 

(3)	Contractual Lease Obligations

In 2010, the Company entered into a long‑term operating lease for offices and manufacturing space in Hillsboro, Oregon. The lease commenced on December 9, 2010 and ends on June 30, 2016. In connection with the lease, the Company entered into an arrangement with the lessor to finance a portion of the cost of the leasehold improvements for the manufacturing space. This loan bears interest at 9% and is amortized over 60 months beginning in July 2011. It has been recorded in other long‑term liabilities. Total leasehold improvements are included in property, plant, and equipment and are being amortized over the term of the lease.

In December 2011, the Company entered into an agreement to lease additional space at its Hillsboro, Oregon facility. The additional lease commenced on May 8, 2012 and terminates in conjunction with the original lease on June 30, 2016. In connection with this lease, the lessor agreed to finance up to $225,000 of the cost of the leasehold improvements for the additional manufacturing space under terms similar to the original agreement. The Company expects to fully utilize this financing, which as of June 2015, had not been finalized.

In August 2013, the Company entered into an agreement to lease additional space at a new facility located in Hillsboro, Oregon. The lease commenced on November 1, 2013 and ends on June 30, 2020.

Rental expense in connection with the facility leases is recognized on a straight‑line basis over the term of the lease including any periods of free rent or lease incentives. Future minimum lease payments under these noncancelable operating leases, and future minimum capital lease payments associated with the original lease, as of December 31, 2014 are as follows:

		Capital				Operating
		lease				leases
Year ending December 31:

Subsequently, these warrants were converted to an equivalent dollar amount of Series C Preferred Share warrants. The exercise price is $0.78 per share (as adjusted for any stock dividends, combinations, splits, recapitalizations, or the like with respect to such shares).

The Company recorded $154 expense related to the fair value of the warrants vested. The expense was classified as cost of goods sold operating expense in the financial statements. During 2010, the Company began to recognize revenue related to this collaboration agreement, resulting in recognition of the proportionate share of the fair value of the warrant associated with the second milestone of the agreement. The Company recorded $157 in 2010 and $131 in 2009 related to the proportionate fair value of the warrant associated with the second milestone, which is classified as a sales discount in the financial statements.

The exercise price is $0.78 per share (as adjusted for any stock dividends, combinations, splits, recapitalizations, or the like with respect to such shares). The Company recorded $65 related to the fair value of the warrants as a debt discount, which was amortized as interest expense over the period of the agreement using the effective-interest method.

In 2013, the Company entered into a loan agreement with Horizon Technology Finance Corporation, as discussed in note 6. In connection with the loan agreement, the Company issued a warrant to the lender to purchase 216,000 (as adjusted for any stock dividends, combinations, splits, recapitalizations, or the like with respect to such shares) shares of Series E Preferred stock. The warrant expires on the earliest of the tenth anniversary of the issue date or in certain scenarios related to the sale of substantially all of the Company's assets. The exercise price is $1.16 per share (as adjusted for any stock dividends, combinations, splits, recapitalizations, or the like with respect to such shares). The Company recorded $182 related to the fair value of the warrants as a debt discount, which will be amortized as interest expense over the period of the agreement using the effective‑interest method. The total amortization expense recognized at December 31, 2014 was $114.

These warrants were issued to certain existing investors who participated in a Series D/D‑1 Preferred Stock financing for a minimum of their pro rata share based upon their ownership of preferred stock prior to the financing. The Company recorded $59 as discount to the Series D/D‑1 Preferred Stock value in the financial statements related to the fair value of the warrants.

The shares of the warrant become exercisable in tranches as four separate milestones are achieved. The exercise price is $0.01 per share (as adjusted for any stock dividends, combinations, splits, recapitalizations, or the like with respect to such shares). During 2011, the Company was qualified by the customer to provide product from its Hillsboro facility, which resulted in the achievement of the first milestone and was qualified to provide product for two particular applications of the customer, which resulted in the achievement of the second milestone. The achievement of these milestones resulted in the vesting of a total of 857,381 of the warrants. The Company recorded $70 of expense related to the fair value of the warrants, which it classified as an operating expense in the financial statements. The warrants' fair value was determined using the Black‑Scholes option‑pricing model using a risk‑free rate of 0.72%, volatility of 62.5%, and a term of 4.5 years. The third milestone for 285,794 shares associated with the qualification for an additional application was not met during the year and per the terms of the agreement thereby expired.

The warrants' fair value was determined using the Black‑Scholes option pricing model using a risk free rate of 0.64%, volatility of 62.5%, and a term of 1.2 years.

(5)	Stock Compensation Plan

In 2004, the Company adopted a stock compensation plan (the 2004 Plan) pursuant to which the Company's board of directors may grant stock options to officers, employees, and certain nonemployees. The 2004 Plan authorizes grants to purchase shares of authorized but unissued common stock. Stock options can be granted with an exercise price less than, equal to, or greater than the stock's fair market value at the date of grant. All awards have 10‑year terms. Most options vest and become fully exercisable after four years from the date of grant.

In 2008, the Company adopted a stock compensation plan (the 2008 Plan) pursuant to which the Company's board of directors may grant stock options to officers, employees, and certain nonemployees. The 2008 Plan authorizes grants to purchase shares of authorized but unissued common stock. Stock options can be granted with an exercise price less than, equal to, or greater than the stock's fair market value at the date of grant. All awards have 10‑year terms. Options vest monthly (with cliff vesting in the first year) and become fully exercisable after four years from the date of grant.

At December 31, 2014, there were 2,311,047 additional shares available for the Company to grant under the 2004 and 2008 Plans. As the Company does not have sufficient historical experience for determining the expected term of the stock option awards granted, the Company has based its expected term for employee grants on the simplified method available under Staff Accounting Bulletin 107 (included in ASC 718, Stock Compensation). Since the Company's shares are not publicly traded and its shares are rarely traded privately, expected volatility is computed based on the average historical volatility of similar entities with publicly traded shares. The risk‑free rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The fair value of each option award is estimated on the date of grant using the Black‑Scholes option‑pricing model that used the weighted average assumptions in the following table:

			2014
Valuation assumptions:
	Expected dividend yield		$	—	%
	Expected volatility			62.50
	Expected term (years)			6.25
	Risk-free interest rate			2.10

Stock option activity during the periods indicated is as follows:

												Remaining
								Number		Average		contractual
								of shares		exercise price		term
Balance at December 31, 2013								10,766,946		0.17		7.56
	Granted							1,906,936		0.19
	Forfeited							(93,146)		0.17
	Expired							(512,154)		0.18
	Exercised							(189,000)		0.19
Balance at December 31, 2014								11,879,582		0.17		6.93
Exercisable at December 31, 2014								7,409,443		0.17		5.90

The weighted average grant‑date fair value of options granted during 2014 was $0.11.

At December 31, 2014, there was $475 of unrecognized compensation cost related to share‑based compensation arrangements granted under the Plans. That cost is expected to be recognized over a weighted average period of 2.6 years. The total fair value of shares vested during the year ended December 31, 2014 was $234.

The Company currently uses authorized and unissued shares to satisfy share‑award exercises.

 

(6)	Financing Arrangements

On May 29, 2013, the Company entered into a $5.0 million loan agreement with Horizon Technology Finance Corporation. The loan bears an effective interest rate of 11.12%. The debt is payable in interest‑only payments until July 2014 and then is payable in 30 monthly payments of approximately $190 and a final payment of $125 at maturity on December 1, 2016. Total proceeds were reduced by the lender by $70 in origination fees and expenses. The debt is discounted for the fair value of attached warrants as discussed in note 4. Loan origination fees of approximately $70 are classified as other assets in the financial statements and are being amortized over the life of the loan using the effective‑interest method. The collateral for the loan is all personal property and fixtures of the Company.

Future minimum payments as of December 31, 2014 are as follows (in thousands):

Year ending December 31:
	2015			$	2,283
	2016				2,217

(8)	Commitments and Contingencies

The Company is involved in various claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the Company's financial position, results of operations, or liquidity.

(9)	Income Taxes

No provision has been made for federal income taxes for the year ended December 31, 2014 as the Company has generated net operating losses since inception.

Significant components of the Company's deferred tax assets as of December 31, 2014 related to net operating losses as well as start‑up costs and accrued liabilities are as follows:

		2014
Components of deferred tax assets:
Net operating loss carryforwards		$	18,065
Other			1,698
Gross deferred tax asset			19,763
Less valuation allowance			(19,763	)
Net deferred tax assets		$	—

The Company has applied a full valuation allowance against its deferred tax assets as of December 31, 2014 and for the period from inception as the Company has had a history of losses.

At December 31, 2014, the Company has federal and state net operating loss carryforwards of approximately $46 million to offset future income. Additionally, the Company has research and development credits of approximately $720. These carryforwards expire in 2024 through 2032.

Pursuant to Internal Revenue Code Sections 382 and 383, the utilization of net operating losses and other tax attributes may be substantially limited due to cumulative changes in ownership greater than 50% that have occurred or could occur during applicable testing periods. The Company has not performed a formal Section 382 analysis, but the preliminary internal analysis indicates that the net operating losses may be limited. Management will determine when a formal analysis is warranted based on generating sufficient taxable income in future periods or the existence of any tax planning strategies that would warrant such a review.
