financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles for interim financial
information and with Rule 8-03 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally
accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal
recurring accruals) considered necessary for a fair presentation have been included. Operating results for the three months ended March
31, 2021 are not necessarily indicative of the results that may be expected for the year ending December 31, 2021. These unaudited condensed
consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included
in the Company&amp;#x2019;s Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the Securities and Exchange Commission,
from which the accompanying condensed consolidated balance sheet dated December 31, 2020 was derived.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0&quot;&gt;&lt;b&gt;Reclassifications&lt;/b&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0&quot;&gt;Reclassification occurred to certain 2020 amounts to conform to the

or events that raise substantial doubt about the Company&amp;#x2019;s ability to continue as a going concern within one year after the date
that the financial statements are issued. The Company is required to make certain additional disclosures if management concludes that
substantial doubt exists about the Company&amp;#x2019;s ability to continue as a going concern and such doubt is not alleviated by the Company&amp;#x2019;s
plans or when the Company&amp;#x2019;s plans alleviate substantial doubt about its ability to continue as a going concern. The evaluation entails
analyzing prospective operating budgets and forecasts for expectations regarding cash needs and comparing those needs to the current cash
and cash equivalent balance and expectations regarding cash to be generated over the following year.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;text-align: justify; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0&quot;&gt;Although the global outbreak of COVID-19 had a significant adverse
impact on the world economy and negatively impacted the Company&amp;#x2019;s revenues, earnings and operating cash flows in 2020, management
believes the Company&amp;#x2019;s operations substantially returned to normal in fiscal 2021 and the Company generated net cash from operations
of $567,000 in the quarter ended March 31, 2021. With the first quarter of fiscal 2021 now completed and the Company&amp;#x2019;s recent investments
in new machinery and equipment paying off, management believes the Company will continue to improve its liquidity. As such, based on current
best estimates of fiscal 2021 sales, confirmed and expected orders, the strength of existing backlog, overall market demand, expected
timing of future cash receipts and expenditures and the Company&amp;#x2019;s ability to access additional liquidity, if needed, the Company
believes it will have adequate cash to support operations through May 31, 2022.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;b&gt;Subsequent Events&lt;/b&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;Management has evaluated subsequent events through

at the lower of cost on a first-in-first-out basis or estimated net realizable value. The Company does not take physical inventories at
interim quarterly reporting periods. For interim periods, substantially all of the inventory value has been estimated using a gross profit
percentage based on annual gross profit percentages of the immediately preceding year as applied to the net sales of the current period.
During the three months ended March 31, 2021, the Company determined that its gross profit for its Complex Machining segment was below
its 2020 gross profit percentages, and accordingly has adjusted margins to less than those of 2020. Adjustments to reconcile the annual
physical inventory to the Company&amp;#x2019;s books are recorded in the fourth quarter.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;b&gt;Credit and Concentration Risks&lt;/b&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;font style=&quot;text-decoration:underline&quot;&gt;Net Sales and Accounts Receivable&lt;/font&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;There were three customers that represented 77.9%

leases. The lease classification affects the expense recognition in the income statement. Operating lease charges are recorded entirely
in operating expenses. Finance lease charges are split, where amortization of the right-of- use asset is recorded in operating expenses
and an implied interest component is recorded in interest expense.

include stock options and warrants using the treasury stock method and convertible notes payable using the if-converted method.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;The following is the calculation of net income

in accordance with FASB ASC 718, &amp;#x201c;Compensation &amp;#x2013; Stock Compensation.&amp;#x201d; Under the fair value recognition provision of
the ASC, stock-based compensation cost is estimated at the grant date based on the fair value of the award. The Company estimates the
fair value of stock options and warrants granted using the Black-Scholes-Merton option pricing model. Stock based compensation expense
for employees amounted to $157,000 and $140,000 for the three months ended March 31, 2021 and 2020, respectively. Stock compensation expense
for directors amounted to $52,000 and $55,000 for the three months ended March 31, 2021 and 2020, respectively. Stock compensation expenses
for employees and directors were included in operating expenses on the accompanying Condensed Consolidated Statements of Operations.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;b&gt;Goodwill&lt;/b&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;Goodwill represents the excess of the acquisition

no impairment of goodwill at March 31, 2021 and 2020.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;b&gt;Recently Issued Accounting Pronouncements&lt;/b&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;text-align: justify; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0&quot;&gt;In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit
Losses (Topic 326) (&amp;#x201c;ASU 2016- 13&amp;#x201d;), which significantly changes how entities will account for credit losses for most financial
assets and certain other instruments that are not measured at fair value through net income. ASU 2016-13 replaces the existing incurred
loss model with an expected credit loss model that requires entities to estimate an expected lifetime credit loss on most financial assets
and certain other instruments. Under ASU 2016-13 credit impairment is recognized as an allowance for credit losses, rather than as a direct
write-down of the amortized cost basis of a financial asset. The impairment allowance is a valuation account deducted from the amortized
cost basis of financial assets to present the net amount expected to be collected on the financial asset. Once the new pronouncement is
adopted by the Company, the allowance for credit losses must be adjusted for management&amp;#x2019;s current estimate at each reporting date.
The new guidance provides no threshold for recognition of impairment allowance. Therefore, entities must also measure expected credit
losses on assets that have a low risk of loss. For instance, trade receivables that are either current or not yet due may not require
an allowance reserve under currently generally accepted accounting principles, but under the new standard, the Company will have to estimate
an allowance for expected credit losses on trade receivables under ASU 2016-13. ASU 2016-13 is effective for annual periods, including
interim periods within those annual periods, beginning after December 15, 2022 for smaller reporting companies. Early adoption is permitted.
The Company will evaluate the impact of ASU 2016-13 on the Company&amp;#x2019;s consolidated financial statements in a future period closer
to the date of adoption.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;text-align: justify; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0&quot;&gt;In August 2020, the FASB issued ASU No.
2020-06, Debt &amp;#x2013; Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging &amp;#x2013; Contracts in
Entity&amp;#x2019;s Own Equity (Subtopic 815-40) (&amp;#x201c;ASU 2020-06), which is intended to address issues identified as a result of the
complexity associated with applying GAAP for certain financial instruments with characteristics of liabilities and equity. For
convertible instruments, ASU 2020-06 reduces the number of accounting models for convertible debt instruments and convertible
preferred stock, and enhances information transparency by making targeted improvements to the disclosures for convertible
instruments and earnings-per-share guidance on the basis of feedback from financial statement users. ASU 2020-06 is effective for
fiscal years, and interim periods in those fiscal years, beginning after December 15, 2021. Early adoption is permitted, but no
earlier than fiscal years beginning after December 15, 2020, including interim periods with those fiscal years. The Company is
evaluating the effect of adopting this new accounting guidance on its financial statements.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;text-align: justify; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0&quot;&gt;On January 1, 2021, the Company adopted ASU
No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (&amp;#x201c;ASU 2019-12&amp;#x201d;), which is intended to
simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in
Topic 740 and also clarifies and amends existing guidance to improve consistent application. This guidance is effective for fiscal
years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. The adoption
of ASU 2019-12 did not have a material impact on the Company&amp;#x2019;s condensed consolidated financial statements.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify&quot;&gt;On January 1, 2021, the Company adopted ASU 2020-04, Reference Rate
Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance for
a limited time to ease the potential burden in accounting for reference rate reform. In January 2021, the FASB issued ASU 2021-01, &amp;#x201c;Reference
Rate Reform (Topic 848): Scope: which clarified the scope of ASU 2020-04. The new guidance provides optional expedients and exceptions
for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria
are met. The amendments apply only to contracts and hedging relationships that reference LIBOR or another reference rate expected to be
discontinued due to reference rate reform. These amendments are effective immediately and may be applied prospectively to contract modifications
made and hedging relationships entered into or evaluated on or before December 31, 2022. The adoption of these ASU&amp;#x2019;s did not have
a material impact on the Company&amp;#x2019;s condensed consolidated financial statements.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;The Company does not believe that any other recently
issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying condensed consolidated

percentage based on annual gross profit percentages of the immediately preceding year as applied to the net sales of the current period.
During the three months ended March 31, 2021, the Company determined that its gross profit for its Complex Machining segment was below
its 2020 gross profit percentages, and accordingly has adjusted margins to less than those of 2020. Adjustments to reconcile the annual
physical inventory to the Company&amp;#x2019;s books are recorded in the fourth quarter.&lt;/p&gt;</us-gaap:InventoryPolicyTextBlock>

  <us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock contextRef="c0_From1Jan2021To31Mar2021">&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;&lt;b&gt;Recently Issued Accounting Pronouncements&lt;/b&gt;&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;text-align: justify; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0&quot;&gt;In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit
Losses (Topic 326) (&amp;#x201c;ASU 2016- 13&amp;#x201d;), which significantly changes how entities will account for credit losses for most financial
assets and certain other instruments that are not measured at fair value through net income. ASU 2016-13 replaces the existing incurred
loss model with an expected credit loss model that requires entities to estimate an expected lifetime credit loss on most financial assets
and certain other instruments. Under ASU 2016-13 credit impairment is recognized as an allowance for credit losses, rather than as a direct
write-down of the amortized cost basis of a financial asset. The impairment allowance is a valuation account deducted from the amortized
cost basis of financial assets to present the net amount expected to be collected on the financial asset. Once the new pronouncement is
adopted by the Company, the allowance for credit losses must be adjusted for management&amp;#x2019;s current estimate at each reporting date.
The new guidance provides no threshold for recognition of impairment allowance. Therefore, entities must also measure expected credit
losses on assets that have a low risk of loss. For instance, trade receivables that are either current or not yet due may not require
an allowance reserve under currently generally accepted accounting principles, but under the new standard, the Company will have to estimate
an allowance for expected credit losses on trade receivables under ASU 2016-13. ASU 2016-13 is effective for annual periods, including
interim periods within those annual periods, beginning after December 15, 2022 for smaller reporting companies. Early adoption is permitted.
The Company will evaluate the impact of ASU 2016-13 on the Company&amp;#x2019;s consolidated financial statements in a future period closer
to the date of adoption.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;text-align: justify; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0&quot;&gt;In August 2020, the FASB issued ASU No.
2020-06, Debt &amp;#x2013; Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging &amp;#x2013; Contracts in
Entity&amp;#x2019;s Own Equity (Subtopic 815-40) (&amp;#x201c;ASU 2020-06), which is intended to address issues identified as a result of the
complexity associated with applying GAAP for certain financial instruments with characteristics of liabilities and equity. For
convertible instruments, ASU 2020-06 reduces the number of accounting models for convertible debt instruments and convertible
preferred stock, and enhances information transparency by making targeted improvements to the disclosures for convertible
instruments and earnings-per-share guidance on the basis of feedback from financial statement users. ASU 2020-06 is effective for
fiscal years, and interim periods in those fiscal years, beginning after December 15, 2021. Early adoption is permitted, but no
earlier than fiscal years beginning after December 15, 2020, including interim periods with those fiscal years. The Company is
evaluating the effect of adopting this new accounting guidance on its financial statements.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;text-align: justify; font: 10pt Times New Roman, Times, Serif; margin: 0pt 0&quot;&gt;On January 1, 2021, the Company adopted ASU
No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (&amp;#x201c;ASU 2019-12&amp;#x201d;), which is intended to
simplify various aspects related to accounting for income taxes. ASU 2019-12 removes certain exceptions to the general principles in
Topic 740 and also clarifies and amends existing guidance to improve consistent application. This guidance is effective for fiscal
years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. The adoption
of ASU 2019-12 did not have a material impact on the Company&amp;#x2019;s condensed consolidated financial statements.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0; text-align: justify&quot;&gt;On January 1, 2021, the Company adopted ASU 2020-04, Reference Rate
Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional guidance for
a limited time to ease the potential burden in accounting for reference rate reform. In January 2021, the FASB issued ASU 2021-01, &amp;#x201c;Reference
Rate Reform (Topic 848): Scope: which clarified the scope of ASU 2020-04. The new guidance provides optional expedients and exceptions
for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria
are met. The amendments apply only to contracts and hedging relationships that reference LIBOR or another reference rate expected to be
discontinued due to reference rate reform. These amendments are effective immediately and may be applied prospectively to contract modifications
made and hedging relationships entered into or evaluated on or before December 31, 2022. The adoption of these ASU&amp;#x2019;s did not have
a material impact on the Company&amp;#x2019;s condensed consolidated financial statements.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;The Company does not believe that any other recently

a loan facility (&amp;#x201c;SNB Facility&amp;#x201d;) with SNB expiring on December 30, 2022. The new loan facility provides for a $16,000,000
revolving loan (&amp;#x201c;SNB revolving line of credit&amp;#x201d;) and a term loan (&amp;#x201c;SNB term loan&amp;#x201d;).&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;In 2020, the Company entered into the First Amendment
to Loan and Security Agreement (&amp;#x201c;First Amendment&amp;#x201d;). The terms of the amendment increase the Term Loan to $5,685,000. The repayment
terms of the term loan were amended to provide monthly principal installments in the amount of $67,679 beginning on December 1, 2020,
with a final payment of any unpaid balance of principal and interest payable on December 30, 2022. Additionally, the date by which certain
subordinated third-party notes need to be extended by was changed from September 30, 2020 to November 30, 2020. The Company has paid an
amendment fee of $20,000.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;The terms of the SNB Facility require that, among
other things, the Company maintain a specified Fixed Charge Coverage Ratio of 1.25 to 1.00 at the end of each Fiscal Quarter beginning
with the Fiscal Quarter ending March 31, 2020. In addition, the Company is limited in the amount of Capital Expenditures it can make.
As of March 31, 2021, the Company was in compliance with all loan covenants. The SNB Facility also restricts the amount of dividends the
Company may pay to its stockholders. Substantially all of the Company&amp;#x2019;s assets are pledged as collateral under the SNB Facility.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;As of March 31, 2021 the future minimum principal

to pay the Company within 30 days after the end of each calendar quarter, commencing April 1, 2017, an amount equal to five (5%) percent
of the net sales of AMK for that quarter until the aggregate payments made to the Company (the &amp;#x201c;Meyer Agreement&amp;#x201d;) equals $1,500,000

Michael and Robert Taglich, pursuant to which the Company assigned to the Purchasers all of their rights, title and interest to the remaining

31, 2023, they have the right to demand payment of their pro rata portion of the unpaid Remaining Amount from the Company (&amp;#x201c;Put

Reporting&amp;#x201d; (&amp;#x201c;ASC 280&amp;#x201d;), the Company discloses financial and descriptive information about its reportable operating segments.
Operating segments are components of an enterprise about which separate financial information is available and regularly evaluated by
the chief operating decision maker in deciding how to allocate resources and in assessing performance.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;The Company follows ASC 280, which establishes
standards for reporting information about operating segments in annual and interim financial statements, and requires that companies report
financial and descriptive information about their reportable segments based on a management approach. ASC 280 also establishes standards
for related disclosures about products and services, geographic areas and major customers.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;The Company currently divides its operations into
two operating segments: Complex Machining, which consists of AIM and NTW; and Turbine Engine Components, which consists of Sterling. Along
with its operating subsidiaries, the Company reports the results of its corporate division as an independent segment.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify&quot;&gt;The accounting policies of each of the segments
are the same as those described in the Summary of Significant Accounting Policies. Intersegment transfers are recorded at the transferors
cost, and there is no intercompany profit or loss on intersegment transfers. We evaluate performance based on revenue, gross profit contribution
and assets employed.&lt;/p&gt;&lt;br/&gt;&lt;p style=&quot;font: 10pt Times New Roman, Times, Serif; margin: 0pt 0&quot;&gt;Financial information about the Company&amp;#x2019;s reporting segments
