INDEPENDENT AUDITOR’S REPORT

To the Board of Directors

Galaxy Tool Holding Corporation

Winfield, KS

Report on the Consolidated Financial Statements

We have audited the accompanying consolidated financial statements of Galaxy Tool Holding Corporation and Subsidiary, which comprise the consolidated balance sheets as of December 31, 2016 and 2015, and the related consolidated statements of income, stockholders’ equity and cash flows for the years then ended and the related notes to consolidated financial statements.

Management’s Responsibility for the Consolidated Financial Statements

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

Auditor’s Responsibility

Our responsibility is to express an opinion on these consolidated 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 consolidated financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the consolidated financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the consolidated 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 consolidated 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 consolidated 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 consolidated financial statements referred to above present fairly, in all material respects, the financial position of Galaxy Tool Holding Corporation and Subsidiary as of December 31, 2016 and 2015, and the results of their operations and their cash flows for the years then ended in accordance with accounting principles generally accepted in the United States of America.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Business Operations—Galaxy Tool Holding Corporation and Subsidiary (d/b/a Galaxy Technologies) is in the business of manufacturing and designing precision tools and parts, fabricating steel and aluminum assemblies, and producing secondary equipment for the customers in the aerospace industry. Additionally, the Company serves customers in the plastic products industry with manufacturing and repairing injection and blow molds and designing component parts and secondary equipment. The Company’s customers are located throughout the United States and internationally. The Company is headquartered in Winfield, Kansas, where it has a manufacturing facility.

Principles of Consolidation—The accompanying consolidated financial statements include the accounts of Galaxy Tool Holding Corporation and its wholly-owned subsidiary, Galaxy Technologies, Inc. (Company). All material intercompany related party balances and transactions have been eliminated in the consolidation.

Use of Estimates—The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect: (1) the reported amounts of assets and liabilities, (2) disclosures such as contingencies, and (3) the reported amounts of revenues and expenses included in such financial statements. Actual results could differ from those estimates.

Cash and Cash Equivalents—For purposes of reporting the statements of cash flows, the Company considers all cash accounts, which are not subject to withdrawal restrictions or penalties, and all highly liquid debt instruments purchased with a maturity of three months or less, to be cash equivalents. The Company maintains its cash in bank deposit accounts that, at times, may exceed federally insured limits. The Company has not experienced any losses in such accounts.

Accounts Receivable, Trade—Trade receivables are carried at original invoice amount less an estimate made for doubtful receivables based on a review of all outstanding amounts on a monthly basis. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer’s financial condition, credit history, and current economic conditions. Trade receivables are written off when deemed uncollectible. Recoveries of trade receivables previously written off are recorded when received.

A trade receivable is considered to be past due if any portion of the receivable balance is outstanding for more than 30 to 60 days, depending on the customer. Interest is not charged on past due accounts.

Inventories—Inventories are stated at the lower of cost or market, with cost determined by the first-in, first-out (FIFO) method. Work-in-process includes material, labor, and allocable factory overhead costs.

Property, Plant and Equipment—Property, plant and equipment are carried at cost. Depreciation is computed using the straight-line method, using estimated useful lives. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts, and any resulting gain or loss is recognized in income for the

AND SUBSIDIARY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

period. The cost of maintenance and repairs is charged to income as incurred; significant renewals and betterments are capitalized. Deduction is made for retirements resulting from renewals or betterments.

Customer List—The Company amortizes acquired customer list, using a straight-line method, over a 7  ¹⁄₂ year period.

Goodwill—Goodwill is not amortized, but is subject to an annual impairment test, as well as when an event triggering impairment may have occurred. The Company has elected to perform its annual analysis during the fourth quarter.

Impairment of Long-Lived Assets—Long-lived assets, other than goodwill, are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated future net cash flows (undiscounted and without interest charges) expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. There were no impairment losses recognized for the years ending December 31, 2016 or 2015.

Deferred Revenue—Deferred revenue represents deposits and progress billings on jobs in progress.

Income Taxes—Deferred tax assets and liabilities are recognized for temporary differences and loss carryforwards. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax bases. When applicable, deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of all the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.

The Company recognizes the financial statement effects of a tax position only when it believes it can more likely than not sustain the position upon an examination by the relevant tax authority.

Revenue Recognition—Revenue is recognized upon shipment of goods. Shipping and handling charges are included in revenue. Shipping and handling costs are included in cost of goods sold.

Advertising Costs—The Company expenses costs of advertising as they are incurred. Advertising expense for the years ended December 31, 2016 and 2015 was $17,105 and $32,043, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Accounting Policies not yet Adopted—The FASB issued a new accounting standard, Revenue from Contracts with Customers, which supersedes nearly all existing revenue recognition guidance under U.S. accounting principles. The core principle of the new standard is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. The new accounting standard defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. accounting principles. The standard is first effective for the Company with its 2019 year.

The FASB issued new accounting standard, Inventory—Simplifying the Measurement of Inventory, which will require the Company to report inventory at lower of cost or net realizable value. The Standard is first effective for the Company with its 2017 year.

The FASB recently issued a new accounting standard, Leases. This new standard will include substantial changes for accounting by lessees; existing operating leases and all new leases, unless immaterial, will require balance sheet recognition. The standard is first effective for the Company with its 2020 year, with early adoption permitted.

The FASB recently issued a new accounting standard, Credit Losses, (also known as CECL) requires the measurement of expected credit losses (allowance for doubtful accounts) be based on historical experience AND current conditions and reasonable and supportable forecasts to determine the collectability of reported amounts. The standard is expected to be effective for the Company with its 2021 year.

The Company is currently evaluating the impact of the pending adoption of these new standards.

Subsequent Events—Subsequent events have been evaluated through April 30, 2018, which is the date the financial statements were available to be issued.

The financial statements for the year ending December 31, 2016 have been restated to conform presentation. The only effect of the restatement was $18,649 reclassed from sales to general and administrative on the consolidated statement of income.

On August 22, 2008, the Company acquired 100% of the stock of Galaxy Tool Corporation and its subsidiary, Encompass Tool & Machine, Inc., under the terms of a stock purchase agreement. The stock purchase transaction was accounted for in accordance with EITF Issue No. 88-16, Basis in Leveraged Buyout Transactions, and EITF Issue No. 90-12, Allocating Basis in Individual Assets and Liabilities for Transactions Within the Scope of EITF Issue No. 88-16. The aggregate purchase price was allocated to the assets and liabilities of the Company based upon an allocation of their respective carryover and fair market values. The carryover interest on the transaction was 38.6%. The portion of the acquisition

recognized at fair value was 61.4%. The caption “consideration paid over consideration contributed by continuing stockholder interests” within the equity section of the accompanying balance sheets represents the difference between the fair value and the carrying value of the 38.6% carryover interest.

Inventories consist of the following at December 31:

Due to higher than expected costs related to several projects, management conducted a thorough review of all work-in-process jobs. As a result, a provision for inventory losses of $75,000 and $265,881 is included in work-in-process as of December 31, 2016 and 2015, respectively. This was based on the Company’s best estimates of product sales prices and expected remaining costs to complete a job. It is at least reasonably possible that the estimates used by the Company to determine its provision for inventory losses will be materially different from the actual amounts or results. These differences could result in materially higher than expected inventory provisions, which could have a materially adverse effect on the Company’s results of operations and financial condition in the near term.

Depreciation expense for the years ended December 31, based on useful lives shown below, consists of:

The net values for intangible assets at December 31 were as follows:

Amortization expense of the customer list for the years ended December 31, 2016 and 2015 was $103,033 and $730,251, respectively.

Goodwill of $8,679,091 was recognized with the acquisition as described in Note 3. The value of goodwill is evaluated for impairment annually. During 2015, a goodwill impairment loss of $5,377,000 was recognized, reducing the carrying value of goodwill to $3,302,091 at December 31, 2016 and 2015. Due to market conditions within the industries in which the Company operates, operating profits and cash flows were lower than expected. Based on that trend, the projected cash flows for the Company were revised. No impairment was taken during the year ending December 31, 2016.

Revolving Line-of-Credit—The Company has a revolving line of credit agreement with a shareholder of the Company that expires August 22, 2019. Under the agreement, the Company may borrow up to $5,000,000. The unpaid principal balance carried an interest rate of LIBOR plus 8% with a minimum interest rate of 10% per annum through September 30, 2015. Starting October 1, 2015, the interest rate was modified to LIBOR plus 4.5% with a minimum of 6.5%. The interest rate as of December 31, 2016 was 6.5%. This revolving line-of-credit is also subject to an unused revolving commitment fee of 1% each month prior to the maturity date, as well as the terms and conditions that are outlined in the security agreement applicable to the subordinated notes payable shown below. At December 31, 2016, $500,000 was available to be drawn on the line-of-credit.

Deferred Income Taxes—Net deferred tax assets (liabilities) consist of the following at December 31:

At December 31, 2016 and 2015, the Company has federal capital loss carryforwards approximating $0 and $6,998,000, state capital loss carryforwards approximating $0 and $9,325,000 respectively, and state tax credits totaling $715,000. In 2015, management determined that such carryforwards may expire before they are utilized, and has established a valuation allowance to offset these tax assets. The current year decrease in the valuation allowance was $2,946,000 due to the net operating losses being eliminated in the debt to equity conversion.

Income Tax Expense (Benefit)—Income tax expense (benefit) for the years ended December 31 is comprised of the following:

The income tax provision differs from the amount of income tax determined by applying the U.S. federal income tax rate to pretax income from operations because of state taxes, nondeductible expenses, change in the valuation allowance and tax credits.

The Company has a defined contribution plan covering all employees meeting the eligibility requirements of the plan. The Company contributes a discretionary percentage of employee contributions as determined annually by the Board of Directors. Retirement plan matching expense for the years ended December 31, 2016 and 2015 was $45,168 and $58,734, respectively.

The Company leases equipment under operating leases expiring in years through 2019. Total rent expense under all operating leases amounted to $211,545 and $301,974 for the years ended December 31, 2016 and 2015, respectively.

The following is a schedule of future minimum rental payments required under the operating leases as of December 31, 2016:

Common stock consists of Class A, B and C shares. Class A and B shares are voting. Class C shares are non-voting. Upon a triggering event, such as a letter of intent to sell the Company, failure to meet certain EBITDA levels, or a default under the loan agreements, the Class B shares may become Class A shares at the option of the holder. Upon corporate liquidation or dissolution, after preferred shareholders receive their liquidation value, the remaining proceeds are divided between Class A and B shares, except that the proceeds allocated to Class B shares are allocated in part to Class C shares based on certain internal rates of return earned by one of the principal stockholders on his preferred and common stock investment in the Company.

Preferred stock consists of series A, B, C, D and E shares carried at the original issue price of $1 per share for Series A and B, $3.50 for Series C, $12.30 for Series D and $100 for Series E. All shares are designated as nonvoting. However, a majority of Series A, C, D and E shareholders must approve certain corporate matters of significance, including amendments to the Articles of Incorporation, share issuances or redemptions, asset or stock sales or mergers, hiring of a Chief Executive Officer and change in number of board members. Dividends on the shares are payable when and if declared by the board. Dividends compound annually and are cumulative. Dividend rates are 15% on Series A shares, 6% on Series B, 15% on Series C and 6% on Series D (prior to February 28, 2013 the dividend rate was 17.5% on Series D) and 17.75% of Series E. Series E shares have first priority in liquidation or dissolution, receiving their original issuance price plus unpaid dividends. Series D shares have second priority in liquidation or dissolution, receiving their original issuance price plus unpaid dividends. Series C shares have third priority receiving 1.5 times their original issuance price plus unpaid dividends; followed by Series A shares and lastly Series B shares, both of which receive their original issue price plus unpaid dividends. Dividend payments receive the same priority with Series C dividends payable only if Series D accumulated dividends have been paid, Series A after Series C dividends are paid and Series B after Series A dividends are paid.

All shares may be redeemed at the holder’s option after six years from the date of issuance. The redemption dates are August 2014 for Series A and B shares, August 2016 for Series C or D shares and December 2021 for Series E, or after satisfaction of all amounts due under loans extended to the Company by the holders (see Note 7). Redemption is mandatory in the case of a qualified public offering of the Company’s common stock.

The agreement between the stockholders also provides for various rights of electing the members of the Company’s Board of Directors and requires consents as to the sale of the Company.

In connection with the acquisition discussed in Note 3, the Company issued warrants to an outside entity for investment banker services to allow the entity to purchase 5,389 Class A common shares for $1 per share. No value was ascribed to the warrants. The warrants expire in August 2020.

At December 31, 2015, $10.52 million of debt was converted to 144,259 shares of preferred Series E stock.

Fair value measurements apply to all assets and liabilities that are being measured and reported on a fair value basis. This enables the reader of the financial statements to assess the inputs used to develop those measurements by establishing a hierarchy for ranking the quality and reliability of the information used to determine fair values. U.S. accounting principles require that assets and liabilities carried at fair value will be classified and disclosed in one of the following three categories:

Level 1 Inputs—Quoted prices in active markets for identical assets or liabilities.

Level 2 Inputs—Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities in active markets; quoted prices for similar assets or liabilities 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 of liabilities.

Level 3 Inputs—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Financial assets and liabilities measured at fair value on a nonrecurring basis including the following:

Goodwill—Goodwill is subject to an annual impairment test. When the carrying value of assets exceeds the fair values goodwill assets are adjusted. This is considered Level 3 in the valuation hierarchy.

As discussed in Note 6, during fiscal 2015, the Company incurred $5,377,000 of goodwill impairment. The carrying value remaining for goodwill was $3,302,091 at December 31, 2016 and 2015.

The Company pays a management service fee to a stockholder. In August 2010, the Company and stockholder entered into an agreement deferring payment until the Board decides payments may resume; however, the fee continues to accrue. Total expense for the years ended December 31, 2016 and 2015 was $225,000. Included in accrued expenses at December 31, 2016 and 2015 are fees of $1,458,750 and $1,233,750, respectively, that remain payable.

As discussed in Note 7, the Company has a line-of-credit and a subordinated note payable with the same stockholder. Interest expense for the years ended December 31, 2016 and 2015 was $824,706 and $1,847,169, respectively, on these agreements.

During 2016, the Company started a partially self-funded insurance plan for employee medical coverage. The Plan has stop-loss insurance that limits the Company’s losses during the policy period to $40,000 per person or an aggregate stop-loss of 100% up to $1,100,000.
