Sales under certain fixed-price contracts, in which the product has no
alternative use to the Company and the Company has enforceable rights to payment
for progress completed to date, inclusive of profit, are accounted for under the
percentage-of-completion method of accounting whereby revenues are recognized
based on estimates of completion prepared on a ratio of cost to total estimated
cost basis. Costs include all material and direct and indirect charges related
to specific contracts.



Adjustments to cost estimates are made periodically and any losses expected to
be incurred on contracts in progress are charged to operations in the period
such losses are determined. However, any profits expected on contracts in
progress are recognized over the life of the contract.



For financial statement presentation purposes, the Company nets progress
billings against the total costs incurred and estimated earnings recognized on
uncompleted contracts. The asset, "costs and estimated earnings in excess of
billings," represents revenues recognized in excess of amounts billed. The
liability, "billings in excess of costs and estimated earnings," represents
billings in excess of revenues recognized.

… as a percentage of net revenues                 24 %               17 %




The Company's consolidated results of operations showed a 39% increase in net
revenues and a decrease in net income of 28%. Revenues recorded in the current
period for long-term construction projects ("Project(s)") were 103% more than
the level recorded in the prior year. We had 34 Projects in process during the
current period compared with 38 during the same period last year. Revenues
recorded in the current period for other-than long-term construction projects
(non-projects) were 17% less than the level recorded in the prior year. Total
sales within the U.S. increased 55% from the same period last year. Total sales
to Asia increased 7% from the same period of the prior year. Sales increases
were recorded over the same period last year to customers involved in
construction of buildings and bridges (85%) as well as in sales to customers in
aerospace / defense (4%) and industrial customers (1%). The significant increase
in domestic sales is primarily from the increase in sales to structural
customers. Many customers in the construction field delayed orders in the prior
period as they considered the potential effects of the COVID pandemic on the
economy.



The gross profit as a percentage of net revenue of 24% in the current period is
higher than the 17% recorded in the same period of the prior year. The increase
in gross profit as a percentage of revenue is primarily due to the significant
increase in domestic sales to structural customers following the COVID related
delay discussed above.


Sales of the Company's products are made to three general groups of customers: industrial, structural and aerospace / defense. A breakdown of sales to the three general groups of customers is as follows:





                          Nine months ended February 28

Aerospace / Defense             34 %                   46 %





At February 28, 2021, the Company had 146 open sales orders in its backlog with
a total sales value of $18.8 million. At February 28, 2022, the Company has 140
open sales orders in its backlog, and the total sales value is $17.4 million.



The Company's backlog, revenues, commission expense, gross margins, gross profits, and net income fluctuate from period to period. The changes in the current period, compared to the prior period, are not necessarily representative of future results.





Net revenue by geographic region, as a percentage of total net revenue for the
nine-month periods ended February 28, 2022 and February 28, 2021 is as follows:

%




Selling, general, and administrative expenses increased by 16% from the prior
year. Outside commission expense decreased by 8% from last year's level due to
lower levels of commissionable sales. Other selling, general, and administrative
expenses increased 20% from last year to this year primarily due to increases in
personnel costs.



The above factors resulted in operating income of $707,000 for the nine months
ended February 28, 2022, as compared to an operating loss of $1,298,000 in the
same period of the prior year.



Other income during the prior period includes $2,096,000 of financial assistance
provided by the U.S. federal government as part of the Coronavirus Aid, Relief
and Economic Security (CARES) Act and the Consolidated Appropriations Act of
2021 (CAA): a.) $1,462,000 of income due to the forgiveness of the loan by the
Small Business Administration (SBA) under the Paycheck Protection Program, and
b.) $634,000 of Employee Retention Credit income.

  Table of Contents



Selling, general, and administrative expenses increased by 12% from the prior
year. Outside commission expense decreased by 70% from last year's level due to
lower levels of commissionable sales. Commissionable sales are lower, despite
total sales being 29% higher than last year's level, as the Company has added
staff to its business development and sales team thereby reducing reliance on
independent, commissioned manufacturers' representatives to help obtain sales
contracts with customers. Other selling, general, and administrative expenses
increased 21% from last year to this primarily due to increases in personnel
costs.



The above factors resulted in an operating loss of $191,000 for the three months
ended February 28, 2022, as compared to an operating loss of $820,000 in the
same period of the prior year.



Other income during the prior period includes $634,000 for funds received from the U.S. federal government as financial assistance under provisions of the Employee Retention Credit program included in the CAA.







Stock Options


The Company has a stock option plan which provides for the granting of nonqualified or incentive stock options to officers, key employees and non-employee directors. Options granted under the plan are exercisable over a ten-year term. Options not exercised at the end of the term expire.





The Company expenses stock options using the fair value recognition provisions
of the FASB ASC. The Company recognized $126,000 and $50,000 of compensation
cost for the nine-month periods ended February 28, 2022 and 2021. This increase
in recognized costs for this incentive resulted from an increase in the number
of options granted in order to attract and retain talented, key employees of the
Company.



The fair value of each stock option grant has been determined using the
Black-Scholes model. The model considers assumptions related to exercise price,
expected volatility, risk-free interest rate, and the weighted average expected
term of the stock option grants. Expected volatility assumptions used in the
model were based on volatility of the Company's stock price for the thirty-month
period ending on the date of grant. The risk-free interest rate is derived from
the U.S. treasury yield. The Company used a weighted average expected term.

The following assumptions were used in the Black-Scholes model to estimate the fair market value of the Company's stock option grants:





                                                       February              February
                                                         2022                  2021
                    Risk-free interest rate:               2.875 %               1.750 %
               Expected life of the options:             4 years             3.9 years

            Expected share price volatility:                  32 %                  34 %
                         Expected dividends:                zero                  zero

     These assumptions resulted in estimated
         fair-market value per stock option:        $       3.42          $       2.88

The ultimate value of the options will depend on the future price of the Company's common stock, which cannot be forecast with reasonable accuracy.

These are mainly inventory, accounts receivable, costs and estimated earnings in
excess of billings, accounts payable, accrued commissions, and billings in
excess of costs and estimated earnings. The Company's primary source of
liquidity has been operations.



Capital expenditures for the nine months ended February 28, 2022 were $722,000
compared to $1,089,000 in the same period of the prior year. As of February 28,
2022, the Company has commitments for capital expenditures totaling $1,700,000
during the next twelve months.



The Company believes it is carrying adequate insurance coverage on its facilities and their contents.

NOTE: Inventory turnover is annualized for the nine-month period ended February 28, 2022.


Inventory, at $5,932,000 as of February 28, 2022, is $97,000 more than the prior
year-end level of $5,835,000. Approximately 88% of the current inventory is work
in process, 4% is finished goods, and 8% is raw materials.



Maintenance and other inventory represent stock that is estimated to have a
product life cycle in excess of twelve months. This stock represents certain
items the Company is required to maintain for service of products sold and items
that are generally subject to spontaneous ordering. This inventory is
particularly sensitive to technological obsolescence in the near term due to its
use in industries characterized by the continuous introduction of new product
lines, rapid technological advances and product obsolescence. Management of the
Company has recorded an allowance for potential inventory obsolescence. There
was no provision for potential inventory obsolescence for the nine-month periods
ended February 28, 2022 and 2021. The Company continues to rework slow-moving
inventory, where applicable, to convert it to product to be used on customer
orders.

The Company combines the totals of accounts receivable, the current asset, CIEB,
and the current liability, BIEC, to determine how much cash the Company will
eventually realize from revenue recorded to date. As the accounts receivable
figure rises in relation to the other two figures, the Company can anticipate
increased cash receipts within the ensuing 30-60 days.

Accounts receivable of $5,268,000 as of February 28, 2022 includes $7,000 of an
allowance for doubtful accounts ("Allowance"). The accounts receivable balance
as of May 31, 2021 of $3,380,000 included an Allowance of $7,000. The number of
an average day's sales outstanding in accounts receivable ("DSO") increased from
42 days at May 31, 2021 to 77 at February 28, 2022. The DSO is a function of 1.)
the level of sales for an average day (for example, total sales for the past
three months divided by 90 days) and 2.) the level of accounts receivable at the
balance sheet date. The level of sales for an average day in the third quarter
of the current fiscal year is 15% less than in the fourth quarter of the prior
year. The level of accounts receivable at the end of the current fiscal quarter
is 56% more than the level at the end of the prior year. The increase in the
level of accounts receivable combined with the decrease in the level of an
average day's sales caused the DSO to increase from last year end to this
quarter-end. The Company expects to collect the net accounts receivable balance
during the next twelve months.



Other receivable is an amount of Employee Retention Credit claimed by the Company for the second calendar quarter of 2021 and was received in the third calendar quarter of 2021.





As noted above, CIEB represents revenues recognized in excess of amounts billed.
Whenever possible, the Company negotiates a provision in sales contracts to
allow the Company to bill, and collect from the customer, payments in advance of
shipments. Unfortunately, such provisions are often not possible. The $1,321,000
balance in this account at February 28, 2022 is 12% less than the prior year-end
balance. This decrease is the result of normal flow of the Projects through
production with billings to the customers as permitted in the related contracts.
The Company expects to bill the entire amount during the next twelve months. 89%
of the CIEB balance as of the end of the last fiscal quarter, August 31, 2022,
was billed to those customers in the current fiscal quarter ended February 28,
2022. The remainder will be billed as the Projects progress, in accordance with
the terms specified in the various contracts.



The balances in this account are comprised of the following components:





                                  February 28, 2022     May 31, 2021

Number of Projects in progress                  10                9




As noted above, BIEC represents billings to customers in excess of revenues recognized. The $708,000 balance in this account at February 28, 2022 is down 48% from the $1,362,000 balance at the end of the prior year.


The balance in this account fluctuates in the same manner and for the same
reasons as the account "costs and estimated earnings in excess of billings,"
discussed above. Final delivery of product under these contracts is expected to
occur during the next twelve months.

down from the $22.0 million at the end of the prior year. $4.1 million of the
current backlog is on Projects already in progress.



Other Balance Sheet Items



Accounts payable, at $1,170,000 as of February 28, 2022, is 35% less than the
prior year-end. Commission expense on applicable sales orders is recognized at
the time revenue is recognized. The commission is paid following receipt of
payment from the customers. Accrued commissions as of February 28, 2022 are
$353,000, 31% more than the $269,000 accrued at the prior year-end. Other
current liabilities increased 33% from the prior year-end, to $2,281,000. The
Company expects the current accrued amounts to be paid or applied during the
next twelve months.


Management believes the Company's cash flows from operations are sufficient to fund ongoing operations and capital improvements for the next twelve months.





Coronavirus Pandemic



Company management currently does not have reason to believe that the COVID-19
pandemic will adversely affect our ability to meet our obligations to our
customers. Our top priorities continue to be the health and safety of our
employees and their families along with supporting our customers.  Thanks to the
careful adherence to our COVID-19 safety measures by our workforce as well as
our customers and suppliers, we remain in a strong position with respect to
being able to process existing orders and we are quite prepared to process new
orders as they are secured.



The liquidity of the Company remains strong at this time. Management, however,
remains concerned that the pandemic may have a significant impact on the various
economies of the world. A prolonged economic downturn would have a negative
impact on our operations and our liquidity.



Our Supply Chain Management team is in communication with our partners around
the globe so that we can be updated on any delays that may occur. To date, there
have been no significant delays in receiving our raw materials, purchased
components, or outside services that affect our final product. The Company has
taken proactive measures when necessary to mitigate the risk associated with
longer lead times on certain raw materials.
