Consolidated Financial Statements 
 
September 30, 2024 and 2023 

 
 
Independent Accountant’s Review Report 
 
December 4, 2024 
To the Board of Directors and Stockholders 
of Microwave Filter Company, Inc. and Subsidiaries 
We have reviewed the accompanying consolidated financial statements of 
Microwave Filter Company, Inc. and Subsidiaries, which comprise the consolidated 
balance sheets as of September 30, 2024 and 2023, and the related consolidated 
statements of operations, changes in stockholders’ equity, and cash flows for the years 
then ended, and the related notes to the consolidated financial statements.  A review 
includes primarily applying analytical procedures to management’s financial data and 
making inquiries of company management.  A review is substantially less in scope than an 
audit, the objective of which is the expression of an opinion regarding the consolidated 
financial statements as a whole.  Accordingly, we do not express such an opinion. 
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 
financial statements that are free from material misstatement whether due to fraud or 
error. 
Accountant’s Responsibility 
Our responsibility is to conduct the review engagements in accordance with 
Statements on Standards for Accounting and Review Services promulgated by the 
Accounting and Review Services Committee of the AICPA.  Those standards require us to 
perform procedures to obtain limited assurance as a basis for reporting whether we are 
aware of any material modifications that should be made to the consolidated financial 
statements for them to be in accordance with accounting principles generally accepted in 
the United States of America.  We believe that the results of our procedures provide a 
reasonable basis for our conclusion. 

 
- 2 - 
 
We are required to be independent of Microwave Filter Company, Inc. and 
Subsidiaries and to meet our other ethical responsibilities, in accordance with the relevant 
ethical requirements related to our reviews. 
Accountant’s Conclusion 
Based on our reviews, we are not aware of any material modifications that should 
be made to the accompanying consolidated financial statements in order for them to be in 
accordance with accounting principles generally accepted in the United States of 
America.

Microwave Filter Company, Inc. and Subsidiaries 
Notes to Consolidated Financial Statements 
Note 1 - Summary of significant accounting policies 
Nature of business - Microwave Filter Company, Inc. (“MFC”) and its wholly-owned 
Subsidiaries (Niagara Scientific, Inc. [“NSI”] and Microwave Filter International, LTD. [“MFI”]), 
(collectively, the “Company”), are engaged in the business of designing, developing, 
manufacturing and selling electronic filters, both for radio and microwave frequencies, to help 
process signal distribution and to prevent unwanted signals from disrupting transmit or receive 
operations.  The Company is located in Syracuse, New York.   
Principles of consolidation - The accompanying consolidated financial statements include 
the accounts of MFC and its wholly-owned subsidiaries, NSI and MFI, a dormant entity.  All 
significant intercompany balances and transactions have been eliminated in consolidation. 
 
Change in accounting principle - As of October 1, 2023, the Company was required to 
adopt Accounting Standards Update (ASU) No. 2016-13, Measurement of Credit Losses on 
Financial Instruments, and all subsequently issued related amendments, which changed the 
methodology used to recognize impairment of the Company’s financial assets.  Financial assets 
held by the Company that are subject to the ASU include accounts receivables.  Under this ASU, 
financial assets are presented at the net amount expected to be collected, requiring immediate 
recognition of estimated credit losses expected to occur over the asset’s remaining life.  This is in 
contrast to previous U.S. GAAP, under which credit losses were not recognized until it was 
probable that a loss had been incurred.  The Company performed its expected credit loss 
calculation based on historical data and analysis, including consideration of then existing 
economic conditions, and expected future conditions.  The adoption of this ASU did not have a 
significant impact on the consolidated financial statements. 
 
Cash and cash equivalents - For purposes of the consolidated statements of cash flows, 
the Company considers all highly liquid investments purchased with a maturity of three months 
or less to be cash equivalents. 
 
Accounts receivable and credit policies - The Company extends credit to business 
customers based upon ongoing credit evaluations.  Accounts receivable are unsecured customer 
obligations due under normal trade terms, generally requiring payment within thirty (30) days from 
the invoice date.  Accounts receivable are stated at the amount billed to the customer, and interest 
is not charged on the accounts.  Customer account balances with invoices over ninety (90) days 
old are considered delinquent.  Payments of accounts receivable are allocated to the specific 
invoices identified on the customer’s remittance advice or, if unspecified, are applied to the 
earliest unpaid invoices. 
 
The carrying amounts of accounts receivable are reduced by valuation allowances that 
reflect management’s best estimate of the amounts that will not be collected.  Management 
believes that the historical loss information that it has compiled is a reasonable base on which to 

 
 
 
- 8 - 
determine estimated credit losses for accounts receivable held at September 30, 2024 and 2023, 
because the composition of the accounts receivable at that date is consistent with that used in 
developing the historical credit-loss percentages (i.e., the similar risk characteristics of its 
customers and its lending practices have not changed significantly over time).  Additionally, 
management has evaluated the current and reasonable and supportable forecasted economic 
conditions in order to determine the expected credit loss rates by aging category for its accounts 
receivable.  As a result, management applied the applicable updated credit loss rates to 
determine the expected credit loss estimated for each aging category.  Further, management 
individually reviews all accounts receivable balances that exceed ninety days from the invoice 
date.  Those receivables identified by management as uncollectable are written oƯ against this 
allowance. 
 
The allowance for credit losses consisted of the following:

$             
Year ended September 30,
 
 
Economic dependency and concentration of credit risk - The Company had sales to two 
customers representing 43% and 42% of total sales for the years ended September 30, 2024 and 
2023, respectively.  Accounts receivable included $49,610 and $226,843 due from these 
customers at September 30, 2024 and 2023, respectively. 
 
The Company maintains cash in bank accounts at various financial institutions.  Amounts 
held in these accounts may, at times, exceed the amounts insured by the Federal Deposit 
Insurance Corporation (“FDIC”).  Amounts in excess of FDIC insurance limits are subject to 
normal credit risk. 
 
Revenue Recognition - The Company recognizes revenue at a point-in-time once control 
over the finished product has transferred to the customer.  Accordingly, revenue is recognized 
when the customer takes title and assumes the risks and rewards of ownership, generally at the 
time of shipment.  When revenue is recognized in accordance with the above terms, the trade 
accounts receivable is recorded. 
 
Inventories - Inventories are valued at the lower of cost (first in, first out “FIFO” method) or 
net realizable value.  Net realizable value is determined as the estimated selling price in the 
normal course of business, minus the cost of completion, disposal and transportation.  Work in 

 
 
 
- 9 - 
process and finished goods include materials, direct labor and allocated factory overhead.  See 
Note 2. 
 
Property, plant and equipment - Property, plant and equipment are recorded at cost.  
Depreciation is computed for financial statement purposes using the straight-line method over 
the estimated useful lives of the assets, while for income tax purposes, depreciation is computed 
using methods and lives prescribed by the appropriate income tax regulations. 
 
Depreciation for consolidated financial statement purposes is computed using asset lives 
as follows: 
 
Buildings 
 
 
 
 
 
 
10 to 30 years 
Machinery & equipment 
 
 
 
 
   3 to 10 years 
OƯice equipment & fixtures  
 
 
 
   3 to 10 years 
 
Expenditures for maintenance and repairs are charged to expense as incurred; major 
renewals and betterments are capitalized.  When items of property, plant or equipment are sold 
or retired, the related cost and accumulated depreciation are removed from the accounts and any 
gain or loss is included in income.  See Note 3. 
 
Customer deposits - Customer deposits consist of down payments from customers on 
future orders.  The deposits remain as liabilities to the Company until the customer orders are 
completed. 
 
Leases - The Company determines if an arrangement contains a lease at contract 
inception.  With the exception of short-term leases (leases with terms less than 12 months), all 
leases with contractual fixed costs are recorded on the balance sheet on the lease 
commencement date as a right-of-use (“ROU”) asset and a lease liability.  Lease liabilities are 
initially measured at the present value of the minimum lease payments and subsequently 
increased to reflect the interest accrued and reduced by the lease payments aƯected.  ROU assets 
are initially measured at the present value of the minimum lease payments adjusted for any prior 
lease payments, lease incentives and initial direct costs.  Certain leases may contain escalation, 
renewal and/or termination options that are factored into the ROU asset as appropriate.  Operating 
leases result in a straight-line rent expense over the life of the lease.  For finance leases, ROU 
assets are amortized on a straight-line basis over the life of the lease and interest accrues to the 
lease liability, which results in a higher interest expense at lease inception that declines over the 
life of the lease.  
 
Variable lease costs are expensed as incurred and are not included in the determination of 
ROU assets or lease liabilities.  The short-term lease for oƯice equipment is recognized in the 
accompanying consolidated statements of operations on a straight-line basis over the lease term.  
See Note 4. 
 
Product warranty - The Company has established a warranty reserve which provides for the 
estimated cost of product returns based upon historical experience and any known conditions or 

 
 
 
- 10 - 
circumstances.  No revenues are recognized in connection with the performance of the warranty 
repair or fulfillment function.  The warranty obligation is aƯected by product that does not meet 
specifications and performance requirements and any related costs of addressing such matters.  
Products must be returned within one year of the date of purchase.  The warranty liability was 
insignificant at September 30, 2024 and 2023. 
 
Research 
and 
development - Research 
and 
development 
expenditures 
were 
approximately $213,000 and $265,400 for the years ended September 30, 2024 and 2023, 
respectively, and are included in selling, general and administrative expenses in the 
accompanying consolidated statements of operations. 
 
Advertising - The Company expenses advertising costs as incurred.  Advertising expenses 
were approximately $29,700 and $21,900 for the years ended September 30, 2024 and 2023, 
respectively, and are included in selling, general and administrative expenses in the 
accompanying consolidated statements of operations. 
 
Income taxes - The Company has elected to be taxed as a C Corporation for Federal and 
state income tax purposes, as explained in Note 6.  Accordingly, the Company provides for income 
taxes using the liability method.  Under the liability method, income taxes are provided for the tax 
eƯects of transactions reported in the consolidated financial statements and consist of taxes 
currently due plus deferred taxes related primarily to diƯerences between the financial reporting 
basis and income tax basis of property and equipment.  Deferred income taxes are also recognized 
for operating losses that are available to oƯset future taxable income.  The deferred tax assets and 
liabilities represent the future tax consequences of those diƯerences, which will either be 
deductible or taxable when the assets and liabilities are recovered or settled.  Valuation 
allowances are established to reserve for deferred tax assets, which may not be realized.  The 
Company has provided a full valuation allowance against its deferred tax assets.  Deferred income 
taxes are recorded using currently enacted income tax rates applicable to the period in which the 
deferred tax asset or liability is expected to be realized or settled.  As changes in tax laws are 
enacted, deferred income taxes are adjusted through the provision for income taxes in the year of 
the change. 
 
The Company has reviewed its operations for uncertain tax positions and believes there are 
no significant exposures.  The Company will include interest on income tax liabilities in interest 
expense and penalties in selling, general and administrative expenses, if such amounts arise.  
There were no interest or penalties for the years ended September 30, 2024 and 2023.  The 
Company is no longer subject to Federal or New York State examinations by tax authorities for the 
closed tax years before 2021. 
 
Retirement plans - The Company maintains both a non-contributory profit-sharing plan 
and a contributory 401(k) plan for all employees over the age of 21 with one year of service.  Annual 
contributions to the profit-sharing plan are determined by the Board of Directors and are made 
from current or accumulated earnings, while contributions to the 401(k) plan were matched at a 
rate of 100% of an employee's first 6% of contributions.  The maximum corporate match was 6% 
of an employee's compensation during fiscal 2024 and 2023. 

 
 
 
- 11 - 
The Company’s matching contributions to the 401(k) plan for the years ended 
September 30, 2024 and 2023, were approximately $62,000 and $69,000, respectively.  
Additionally, the Company may make discretionary contributions to the non-contributory profit-
sharing plan.  There were no discretionary contributions in fiscal 2024 and 2023. 
 
Treasury stock - The Company purchased 342 shares and 1,346 shares from various 
shareholders during the years ended September 30, 2024 and 2023, respectively.  The purchased 
shares increased Treasury stock on the accompanying consolidated balance sheets by $171 and 
$673 at September 30, 2024 and 2023 respectively. 
 
Use of estimates - The preparation of consolidated financial statements in conformity with 
generally accepted accounting principles requires management to make estimates and 
assumptions that aƯect the reported amounts of assets and liabilities and disclosure of 
contingent assets and liabilities at the date of the consolidated financial statements and the 
reported amounts of revenues and expenses during the reporting period.  Actual results could 
diƯer from those estimates. 
 
Subsequent events - Management 
has 
evaluated 
subsequent 
events 
through 
December 4, 2024, the date which the consolidated financial statements were available for issue.  
There have been no subsequent events that would require disclosure or adjustment to the 
consolidated financial statements.

received a full refund for the capitalized amount.  
Note 4 - Operating lease commitments 
The Company entered into an operating lease arrangement for office equipment in 
Syracuse, New York, beginning November 15, 2022, following expiration of their previous 
operating lease arrangement, which matured in March 2022 and had since been rented on a 
month to month basis.  The total right-of-use asset obtained in exchange for new operating lease 
liability for the lease period is stated below.  Total operating lease expense was $5,007 and $5,705

The research and development tax credit carryforwards and NOL carryforwards generated 
through September 30, 2024, of approximately $399,000 and $925,000 respectively, expire at 
various times through 2041.  As required by the Financial Accounting Standards Board (FASB) 
Accounting Standards Codification (ASC) 740, the Company has evaluated the positive and 
negative evidence bearing upon the realization of its net deferred tax assets.  The Company has 

 
 
 
- 15 - 
determined that, at this time, it is more likely than not that the Company will not realize all of the 
benefits of Federal and state net deferred tax assets, and, as a result, a valuation allowance was 
established.  Pursuant to the CARES Act, there is no limit to the usage of the Company’s NOLs 
originating through the fiscal tax years ending on or before September 30, 2020.  The Company is 
currently open to audit under the statute of limitations by the Internal Revenue Service (IRS) for 
the fiscal years ended September 30, 2021 through September 30, 2024.
