Acquisition

On June 30, 2023, the Company entered into an Asset Purchase and License Agreement with Honeywell whereby Honeywell sold certain assets and granted perpetual license rights to manufacture and sell licensed products related to its inertial, communication and navigation product lines to the Company. The Transaction involves a sale of certain inventory, equipment and customer-related documents; an assignment of certain customer contracts; and a grant of exclusive and non-exclusive licenses to use certain Honeywell intellectual property related to its inertial, communication and navigation product lines to repair, overhaul, manufacture sell, import, export and distribute certain products to the Company. The Transaction allows the Company to diversify its product offerings in the aerospace industry. The Company determined that the Transaction met the definition of a business under ASC 805; therefore, the Company accounted for the Transaction as a business combination and applied the acquisition method of accounting.

In connection with the Transaction, the Company entered into a term loan with PNC Bank, National Association for $20.0 million to fund a portion of the Transaction (the “Term Loan”) – refer to Note 9, “Loan Agreement” for further details. The purchase consideration transferred at the Acquisition Date was $35.9 million, which was entirely cash.

In the third quarter of 2024 and within one year from the Acquisition Date, the Company finalized its accounting of the Transaction. The following purchase price allocation table presents the Company's estimates of the fair value of assets acquired and liabilities assumed as of the Acquisition Date, and subsequent measurement period adjustments recorded during the one-year period ended June 30, 2024:

	Amounts Recognized as of
	Acquisition Date		Measurement			Purchase Price
	(as previously reported)		Period Adjustments			Allocation
Cash consideration	$	35,860,000	$	—		$	35,860,000
Total consideration	$	35,860,000	$	—		$	35,860,000
							—
Prepaid inventory (a)	$	10,036,160	$	(3,012,626)	(d)	$	7,023,534
Equipment		2,609,000		3,675,000	(d)		6,284,000
Construction in progress		1,238,000		—			1,238,000
Intangible assets (b)		20,900,000		(3,660,000)	(d)		17,240,000
Goodwill (c)		4,608,041		(533,575)	(d)(e)		4,074,466
Assets acquired		39,391,201		(3,531,201)			35,860,000
Accrued expenses		(3,531,201)		3,531,201	(e)		—
Liabilities assumed		(3,531,201)		3,531,201			—
Net assets acquired	$	35,860,000	$	—		$	35,860,000

(a) Prepaid inventory consists of raw materials and finished goods acquired by the Company but not in the Company’s physical possession as of the Acquisition Date. The fair value of raw materials was estimated to equal the replacement cost. The fair

value of finished goods was determined based on the estimated selling price, net of selling costs and a margin on the selling activities, which resulted in a change in the value of the finished goods.

(b) Intangible assets consist of license agreement related to the license rights to use certain Honeywell intellectual property and customer relationships and are recorded at estimated fair values. The estimated fair value of the license agreement is based on a variation of the income valuation approach and is determined using the relief from royalty method. The estimated fair value of the customer relationships is based on a variation of the income valuation approach known as the multi-period excess earnings method. Refer to Intangible assets within Note 2, “Supplemental Balance Sheet Disclosures” for further details.

(c) Goodwill represents the excess of the purchase consideration over the estimated fair value of the assets acquired and liabilities assumed. The goodwill recognized is primarily attributable to the expected synergies from the Transaction. Goodwill resulting from the Transaction has been assigned to the Company’s one operating segment and one reporting unit. The goodwill is not expected to be deductible for income tax purposes. Further, the Company determined that the goodwill was not impaired as of June 30, 2024 and as such, no impairment charges have been recorded for the three- and nine-month periods ended June 30, 2024; the Company also determined that the goodwill was not impaired as of September 30, 2023.

(d) In the third quarter of 2024 and within one year from the Acquisition Date, the Company identified measurement period adjustments related to fair value estimates. The measurement period adjustments were due to the refinement of inputs used to calculate the fair value of the prepaid inventory, equipment, license agreement and customer relationships based on facts and circumstances that existed as of the Acquisition Date. One of the refinements of inputs used was a change in classification of prepaid inventory to equipment of $3.7 million. The adjustments resulted in an overall increase to goodwill of $3.0 million. As a result of the measurement period adjustments to the estimated fair values of equipment and customer relationships, during the third quarter of 2024, the Company recognized $218,623 additional depreciation expense in cost of sales and $67,500 additional amortization expense in selling, general and administrative respectively, related to the effects that would have been recognized in previous quarters if the measurement period adjustments were recognized as of the Acquisition Date. For the remaining measurement period adjustments, the change to the preliminary fair value estimates did not have a material impact to the condensed consolidated statement of operations.

(e) During the fourth quarter of 2023, the Company identified measurement period adjustments related to the fair value estimates for accrued expenses. While the Asset Purchase and License Agreement indicated an amount of liabilities related to open supplier purchase orders to be assumed by the Company as of the Acquisition Date, it was determined that there were no actual liabilities outstanding related to these open supplier purchase orders as of the Acquisition Date; therefore, the $3.5 million assumed liabilities preliminarily recorded were reversed. The adjustments resulted in an overall decrease to goodwill of $3.5 million; the adjustments have no impact to the condensed consolidated statement of operations.

Transition services agreement

Concurrent with the Transaction, the Company entered into a transition services agreement (the “TSA”) with Honeywell, at no additional costs, to receive certain transitional services and technical support during the transition service period. The Company accounted for the TSA separate from business combination and have recognized $140,000 in prepaid expenses and other current assets at September 30, 2023 within the condensed consolidated balance sheets for the services to be received in the future from Honeywell. The prepaid expense related to the TSA was determined using the with and without method.

Acquisition and related costs

In connection with the Transaction, the Company incurred no acquisition costs for the three- and nine-month periods ended June 30, 2024. The Company incurred acquisition costs of $408,961, which were expensed as incurred and included in selling, general and administrative expenses in the condensed consolidated statement of operations for the year ended September 30, 2023; of that amount, the Company incurred acquisition costs of $262,099, which were expensed as incurred and included in selling, general and administrative expenses in the condensed consolidated statement of operations for the three- and nine-month periods ended June 30, 2023. The debt issuance costs related to the Term Loan were not material.
