The business
What it sells, where the money comes from, the kind of company it is.
The business in brief
read the 10-K →What this business is and what moves its needle, from its own SEC filings.
- What it is
- Revenue is Electronic Products (83%) and Injection Molded Plastic Parts (17%).
- Situation
- Cyclical. Margins collapse and recover repeatedly across the record; a single year, good or bad, misstates the through-cycle earning power.
- What moves the needle
- Gross margin has run about 17% and operating margin about 3.0% through the cycle, a thin spread that turns the result on volume and the cost of what it sells far more than on the price it sets. On a spread this thin the operating result swings hard on small moves in cost or volume — it has ranged from −12% to 5.5% over the years, so the cost line is where the needle moves. Inventory runs near 20% of sales, so how fast it turns back into cash — and the risk of writing it down when demand softens — sits alongside the margin. On its own account, the filing leans hardest on litigation & contingencies, set against the numbers in what the filing emphasizes, below.
- Is it a good business?
- Return on capital has rarely cleared the cost of capital (median 3%, above 15% in 0 of 10 years). By owner earnings: roughly 5% of revenue reaches owners as cash, though it swings. The cycle and the balance sheet decide this one; the worst year tells more than the median, and the rest is in the 10-K.
Every line is arithmetic on the company's filings, shown in full in the sections below.
Where the money comes from
read the 20-F →The biggest segment, Electronic Products, is also where the profit is made: 83% of revenue and 100% of the profitable segments' operating profit. Injection Molded Plastic Parts ran a $1M operating loss.
- Electronic Products83%$56M100% of profit
- Injection Molded Plastic Parts17%$11Mloss of $1M
From the segment footnote of the company's own 20-F. Shares are of total revenue; the profit bar shows each segment's share of the profitable segments' operating profit (a loss-making segment carries its loss in dollars in the legend, not a share of the bar), before unallocated corporate costs.

Where the cash went
ReinvestBuybacksDividendsAcquisitionsRetainedEach year's operating cash, by what management did with it: the mix, and how it drifts.
Net income is the accountant's number; owner earnings is the cash an owner could take out. The walk between them, off the cash-flow statement, and whether the gap is widening or holding.
In fiscal 2025 the business turned $11M of profit into $13M of owner earnings: more cash than the profit line showed, after the non-cash charges and the capital it put back in.

Maintenance capex is estimated as depreciation where a growing business invests above it; free cash flow is the figure the scorecard's free-cash margin reads.

Owner’s Scorecard
Will it survive?
- No meaningful interest burdenLittle or no interest expense reported
What this means
Little or no interest expense reported, the business isn't leaning on lenders to operate.
- Net cash, debt-freeCash $28M + ST investments $25M − debt $0
What this means
Cash and short-term investments exceed every dollar of debt by $53M, on net the company owes nothing, and can act from strength when others can't. Net debt is the leverage figure that matters: the cash is already set against the debt. Strategic or illiquid investments aren't counted here.
- Long (60+ days)DSO 54 + DIO 64 − DPO 39 days
What this means
Days cash is tied up between paying suppliers and collecting from customers. Lower is better; a long cycle means growth itself eats cash.
Is it a good business?
- Not enough dataIndustry peers: median 11%
What this means
The filing data didn't include the inputs for this check.
- High, recently turned positivelatest $13M = operating cash $14M − maintenance capex $332K; positive each of the last 3 years, after an earlier loss stretch (10-yr median 4%)Industry peers: median 8%
What this means
What an owner could take out without starving the business: operating cash less the maintenance capital it must spend to hold its position — Buffett's owner earnings. That's 20% of revenue this year, a 4% median across 10 years.
- Cash-backedCash from ops $14M ÷ net income $11M
What this means
How much of reported profit showed up as operating cash. Above 1× is reassuring; well below suggests earnings lean on accruals. One year is noisy, growth and working-capital swings distort it, and this is operating cash, not free cash. Watch the multi-year trend.
How is the cash used?
- Reinvests most of itDividends + buybacks $3M ÷ Owner Earnings $13M
What this means
Of $13M Owner Earnings, $3M (24%) went back to shareholders, $3M dividends, $0 buybacks. Returning most of it is the mark of a mature business with little left to reinvest at a high return; reinvesting most could mean a long runway, or empire-building. The split doesn't say which; the return earned on it (see ROIC) does.
- Investing or harvesting? 0.22×HarvestingCapex $332K ÷ depreciation $2M
What this means
Descriptive, not a grade. Above ~1× means investing faster than assets wear out (growth, or, sustained for years, today's earnings carrying less depreciation than tomorrow's will). Below means spending less than it's wearing out (efficiency, or a melting asset base). The ratio won't tell you which; the filings will.
Graham’s defensive tests · 3 of 5 met
Graham’s numerical criteria for the defensive investor (The Intelligent Investor, ch. 14), run on the filings. A floor of safety, not a buy signal; many fine modern businesses fail his strictest liquidity rules by design.
- Adequate size MissRevenue ≥ $2B · $68M
What this means
Big enough to weather a storm. Graham's 1972 floor was ~$100M of sales (≈ $700M today); we use a $2B revenue line as a conservative modern stand-in.
- Strong liquidity PassCurrent ratio ≥ 2× · 5.45×
What this means
Current assets at least twice current liabilities, near-term bills covered without touching the business. Strict by design: many cash-rich modern firms run leaner and miss it, holding their cushion in longer-dated securities.
- Earnings stability MissA profit every year (10-yr record) · 2 loss years
What this means
Graham wanted earnings in each of the past ten years, the stability a defensive owner leans on.
- Dividend record PassUninterrupted dividends · paid every year (10)
What this means
An unbroken dividend was Graham's mark of durability. He wanted twenty years; the filings show about ten, and a single suspension breaks the streak. Non-payers, many fine modern compounders, fall outside his defensive net by design.
- Earnings growth PassEarnings +33% over the record · +694%
What this means
At least a third more earnings than a decade ago, averaging three years at each end. Net income (not per-share), so stock splits don't distort it, buybacks and dilution show up in the share-count line instead.
- Moderate price —P/E ≤ 15 and P/E × P/B ≤ 22.5 · decided by the price
What this means
Graham's valuation gate, the wall he kept between a sound business and a sound investment. Three-year average earnings are $436.82/share (latest year $698.18), the averaged base the calculator's gate runs on, and book value is $6401.30/share. Enter a price in “What the price implies” just below for the P/E, P/B, and whether it clears. But this is the rule Buffett outgrew: there's no hard P/E law, and a wonderful business can deserve a far richer multiple if the thesis holds, treat it as the bargain-hunter's floor, not a verdict on the price.
Durability & moat, 2016–2025
Whether the record’s returns held, and what the capital reinvested earned.
- Profitable years 8 of 10
What this means
Lost money in 2 year(s), look at what happened there before trusting the average.
- Operating margin −5% → 5% (3-yr avg ends)
What this means
Through the cycle the operating margin widened — about −5% early to 5% lately, median 3% — pricing power intact or improving.
- Worst year 2016 · −12.0% op. margin
What this means
Operations went underwater in 2016, understand why before trusting the good years.
- Share count −0.1%/yr
What this means
Roughly flat share count, little dilution, little buyback.
- Dividend record rising
What this means
Paid and raised the dividend across the record, the continuity Graham prized.
Does AI threaten the moat?
Moderate contestabilityAI is likely to reshape costs and some products here without clearly contesting or sparing the core moat; how the company itself frames it is the tell.
The question is whether a moat the record shows as durable outlasts a technology that lowers the cost of part of what the firm sells. The durability is read in the record above, the filing's own framing of AI beside it; the industry label decides nothing on its own.
Read from the filing's own risk factors, paired with the industry's structure under its SIC code; the durability is read above, the price below.

How the cash was used, 2016–2025
Over the record, the business generated $63M of operating cash; how management split it reads as a cash builder, a large share of cash simply built up on the balance sheet.
- Reinvested$9M · 15%
- Dividends$25M · 39%
- Buybacks$308K · 0%
- Retained (debt / cash)$29M · 46%
- Returned to owners$25M
46% of the owner earnings the business produced over the span, $25M as dividends and $308K as buybacks.
- Source of fundingOperating cash
Operating cash covered reinvestment and returns; over the span cash and short-term investments rose $41M.
- Average price paid for buybacks—
Buybacks ran $308K over the span, but the filings don't tag the share count needed to deduce the average price paid.
- Net change in share count−0.8%
The diluted count barely moved (16M to 16M): buybacks roughly offset the stock issued to staff.
- Dividend record$0.20/sh
Paid in 10 of the years on record, the per-share dividend growing about 7% a year. It was cut at least once along the way.
- Return on what it retained69%
Of the earnings it kept rather than paid out ($18M over the span), annual owner earnings (first three years vs last three) grew $13M, so each retained $1 added about 0.69 of yearly owner earnings. Buffett's test, run on owner earnings instead of market value.
Buybacks are gross of stock issued to staff; the share-count line above is the net of that, the figure that decides whether owners gained. The average price paid blends a year of purchases (and any accelerated repurchase), so it is close, not exact. The record of where the cash went and on what terms.
Inverting the record
Invert: instead of why Deswell Industries Inc. is a good business, the question is what would make owning it a mistake, and whether those marks are in the record. Disconfirming tests across 2016–2025.
None of the 4 tests turned up a mark; each came back clean. A clean panel says only that these particular ways of being wrong are not written into the record.
- Is it less profitable than it was?
- Did the share count rise anyway?
- Did reported profit become cash?
- Did receivables and inventory outpace sales?
Each test is read from the filings and is noisy alone; a flag can mark a cyclical trough or a year of heavy investment as easily as a problem. The filing says which.
