VICR, Vicor Corporation
We design, develop, manufacture, and market modular power components and power systems for converting electrical power.
In electrically-powered devices utilizing alternating current ("AC") voltage from a primary AC source (for example, a wall outlet), a power system converts AC voltage into the stable direct current ("DC") voltage necessary to power subsystems and/or individual applications and devices (known as "loads").
Since the Company was founded, we have pursued continuous innovations in product design and achievements in product performance, largely enabled by our focus on the research and development of advanced technologies and processes, often implemented in proprietary semiconductor circuitry, materials, and packaging.

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 AdvancedProducts (61%) and BrickProducts (39%).
- 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 47% and operating margin about 6.3% through the cycle, a solid spread between what it charges and what the product costs to make. The operating margin has swung widely — from −3.2% to 20% — on a steadier 47% gross margin, so what moves it sits below the gross line, in operating spend and one-off charges more than in the cost of the product itself. Inventory runs near 19% of sales, so how fast it turns back into cash — and the risk of writing it down when demand softens — sits alongside the margin. Read this kind of business on process leadership and the capex cycle. On its own account, the filing leans hardest on pricing power & competition, set against the numbers in what the filing emphasizes, below.
- Is it a good business?
- Return on capital has sat near the cost of capital (median 10%). The steadier read is owner earnings: roughly 8% 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 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 $119M of profit into $119M of owner earnings: more cash than the profit line showed, after the non-cash charges and the capital it put back in.

Owner earnings is the cash an owner could pull out without starving the business: operating cash less the capital it must spend to hold its position .
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 $403M − debt $0
What this means
Cash and short-term investments exceed every dollar of debt by $403M, 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.
- Not enough data
What this means
The filing data didn't include the inputs for this check.
Is it a good business?
- Not enough dataIndustry peers: median 9%
What this means
The filing data didn't include the inputs for this check.
- Solid through the cycle10-yr median margin, range -5%–29%; latest $119M = operating cash $140M − maintenance capex $20MIndustry peers: median 7%
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 29% of revenue this year, a 8% median across 10 years.
- Cash-backedCash from ops $140M ÷ net income $119M
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 $35M ÷ Owner Earnings $119M — this fiscal year
What this means
Of $119M Owner Earnings, $35M (30%) went back to shareholders, $0 dividends, $35M 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. This year's proportion is 30%; across the record (2016–2025) it is 12%, the capital-allocation section below.
- Investing or harvesting? 0.98×MaintainingCapex $20M ÷ depreciation & amortization as filed $21M
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 · 2 of 4 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 · $408M
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× · 8.99×
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 NearA profit every year (10-yr record) · 1 loss year
What this means
Graham wanted earnings in each of the past ten years, the stability a defensive owner leans on.
- Dividend record —Uninterrupted dividends · no dividend line tagged in the data
What this means
An unbroken dividend was Graham's mark of durability. This record carries no dividends-paid line in any year — common for partnerships, whose distributions file under tags the chain doesn't read — so the criterion is withheld rather than judged on silence.
- Earnings growth PassEarnings +33% over the record · +595%
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 $1.31/share (latest year $2.61), the averaged base the calculator's gate runs on, and book value is $15.65/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 9 of 10
What this means
Lost money in 1 year(s), look at what happened there before trusting the average.
- Operating margin 2% → 11% (3-yr avg ends)
What this means
Through the cycle the operating margin widened — about 2% early to 11% lately, median 6% — pricing power intact or improving.
- Worst year 2016 · −3.2% op. margin
What this means
Operations went underwater in 2016, understand why before trusting the good years.
- Share count +1.8%/yr
What this means
The share count is rising, dilution works against you on a per-share basis.
- How management talks about it Promotional
What this means
The record is compounding, but the filing leans on a promoter’s vocabulary rather than the per-share, return-on-capital terms an owner uses. The results back the talk here; the register is still worth noting.

How the cash was used, 2016–2025
Over the record, the business generated $434M of operating cash; how management split it reads as a reinvestor, most operating cash is plowed back into the business.
- Reinvested$269M · 62%
- Buybacks$36M · 8%
- Retained (debt / cash)$128M · 30%
- Returned to owners$36M
12% of the owner earnings the business produced over the span, $0 as dividends and $36M as buybacks.
- Source of fundingOperating cash
Operating cash covered reinvestment and returns; over the span cash and short-term investments rose $348M.
- Average price paid for buybacks—
Buybacks ran $36M over the span, but the filings don't tag the share count needed to deduce the average price paid.
- Net change in share count21.7%
The diluted count rose from 39M to 47M: issuance (stock pay, deals) outran any buybacks, so owners were diluted on net.
- Dividend record—
No dividend line was reported in the filing data over the span; the record here neither confirms nor rules out a payout.
- Return on what it retained24%
Of the earnings it kept rather than paid out ($282M over the span), annual owner earnings (first three years vs last three) grew $67M, so each retained $1 added about 0.24 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.
Management, ownership & pay
read the proxy →From the proxy: how much of the business the people running it own, and how they are paid, beside what the business earned for its owners in the same years.

Both pay figures are the company’s own, from the pay-versus-performance table its proxy statement files. “As filed” is the Summary Compensation Table total: salary, bonus, and equity awards at their value on the day of grant. “Actually paid” is the SEC’s prescribed recalculation, which re-marks those equity awards to what they became as they vested; it can swing far above or below the filed figure in either direction, and negative years occur. Owner earnings are the whole business's, from the record above, for the same fiscal years.

reverse-DCFType today's close and see the owner-earnings growth you'd have to believe to justify it, beside what Vicor Corporation has delivered.
Vicor Corporation’s latest year runs above its own through-cycle margin — the reported figure may flatter a peak. So the tool opens on the through-cycle base, Graham’s averaging cutting both ways; clear the toggle below to read the latest year exactly as reported.
Through the cycle, Vicor Corporation earns about $35M on its 8.5% median owner-earnings margin. This year’s 29.2% margin runs above that; the reported figure may flatter a peak you'd be paying on. Normalize, below, values the price on that through-cycle figure rather than the latest year.
