MACOM: The Next Twelve Months Look Better Than the Price

MACOM: The Next Twelve Months Look Better Than the Price

MACOM, the Lowell, Massachusetts maker of the analog and optical chips that move data inside AI data centers, posted the strongest quarter in its run as an AI-optics story, and the market promptly handed the stock back. On August 6 the company reported fiscal third-quarter revenue of $342.2 million, up 35.8% year over year, and adjusted earnings of $1.40 a share, a nickel above the $1.35 consensus, on a record 1.6-to-1 book-to-bill — meaning customers ordered one and a half times more product than the company could ship.

Then it guided to $415 million to $425 million in revenue for the fiscal fourth quarter, another 21% to 24% sequential jump, at wider margins — and the stock closed up 3% near $311 the day the market was told. What followed was the part that matters. The stock fell 9.2% in a single session on August 18, then dropped 7.0% to $272.31 last Wednesday as the whole semiconductor group sold off in a broad rotation. At roughly $267 today, MACOM trades below where it sat before the report and about a third below its 52-week high near $419.

None of that decline was business news. There was no downgrade in the selloff, no guidance cut, no inventory write-down — the price moved because investors took profits in a sector-wide chip shakeout and the company said nothing wrong. The crowd is still pricing the old story, the one where a stock with a huge multiple is a setup for disappointment. The quarter argues the opposite, and the next twelve months are the part of the timeline the market is not looking at.

The quarter's proof point

The composition matters more than the headline. Data center revenue — the reason this stock went from roughly $120 to over $400 in a year — came in at $137.6 million, up 40% sequentially, on 800G and 1.6T PAM4 products and 200-gig photodetectors that are just reaching volume. Management expects that product line to grow around 74% for the full fiscal year. Adjusted gross margin hit 59.7%, adjusted operating margin 31.5%, and the fourth-quarter guide calls for more: 60% to 61% gross margin and about 37% operating margin. Revenue rising 20%-plus a quarter against a mostly fixed cost base does that. It is operating leverage, which is the entire argument.

One line item deserves a straight look. The GAAP EPS figure of $1.28 included a $41.5 million fair-value gain on an investment, booked below operating income. Strip it out and GAAP profit is about 75 cents — still up from 48 cents a year earlier. The adjusted numbers the market actually trades on beat without the gain, and the guidance does not depend on it. Flag it, note it, move on.

The free cash flow most coverage skipped

Here is the number that keeps this stock on the wrong side of every sector wobble, and it is the one that matters most. Trailing free cash flow is only around $165 million, down year over year even as revenue grew 28% over the same stretch. Against a market cap near $20 billion, that is roughly 120 times trailing free cash flow — an absurd-looking premium if you stop at the headline.

The gap is not broken economics; it is a working-capital build. In the first nine months of the fiscal year MACOM generated $201.6 million of operating cash flow, then watched receivables consume $30.5 million of it and inventory consume $43.8 million. When you hold a 1.6-to-1 book-to-bill, you buy inventory before you ship it; that is the price of honoring the demand. What you do not need to do is buy capacity. MACOM owns its fabs, and capital spending is guided to just $60 million to $65 million for the year, roughly flat into next year. Margins up, capex flat, working capital eventually stopping its growth: that is the recipe for the cash to catch the multiple.

The fourth-quarter guide implies about 38 cents of adjusted net income per dollar of revenue. Hold something near that margin on a fiscal year tracking toward $1.3 billion now and $1.7 billion next, and non-GAAP EPS lands around $7 with free cash flow moving from $165 million toward $500 million-plus. No higher multiple required — the same price simply sits on more earnings and more cash. The 120-times trailing-cash number quietly becomes about 40 times next year's cash.

The scorecard

The market is anchored to this year's denominator. Add the guided fourth quarter — about $2.00 of adjusted EPS — to the three quarters already reported (1.02, 1.09, 1.40, a third straight quarter of beats) and the fiscal year ends near $5.50. At $267, that is about 48 times, the frightening number the selloff is trading against. A year out, on the $7.25 bridge above, the same stock costs about 37 times next year's earnings. The premium has not vanished; the earnings have simply started catching it, which is the part the crowd has not priced.

Two checks line up. The selloff did not move the analysts: the average price target of about $342 is intact, with 10 of the 14 ratings tracked at buy, and AInvest's aggregate signal still labels the shares a buy. The Street was never the problem — the price reset was. If next year's $7 actually shows up and the stock keeps a premium multiple in the mid-40s, below the 48 it pays on this year's earnings, that is roughly $335, about 25% above today's price. The aggressive end of the analyst range sits near $450. No DCF required; the arithmetic fits on a napkin. I can be wrong again, but the bridge is explicit: my target is around $335, twelve months out.

What breaks it

The risk is sitting right inside the quarter. A record book-to-bill is exactly the kind of number that appears when customers double-order a capacity-constrained part, so that ratio is the tripwire: if it slips toward 1.0 while inventory keeps rising — already at $281.5 million versus $237.8 million at fiscal year-end — the working-capital release I'm counting on becomes a cash trap and the premium loses its proof. The second tripwire is data center: if the sequential acceleration stalls or hyperscaler budgets tighten, next year's EPS slides back toward $6 and the stock is fairly valued right here. Management itself flagged rising labor, electricity, and raw-material costs and a tax rate that climbs off its 3% floor next year. The balance sheet stays clean through the stress case — roughly $320 million of net cash — so the failure mode is an earnings question, not a solvency one.

The discipline is unchanged. Hold through the sector noise if the company ships the quarter it just guided to — revenue past $400 million, margins toward 60% gross, book-to-bill holding above one — because that is the proof the cash flow is coming. If the book-to-bill breaks or inventory piles up without the revenue, the setup is broken and I'm out without ego. The next twelve months are the part of this story the market is not pricing, and a business that just posted record bookings at 31.5% operating margins is not the kind of proof point you ignore because the tape had a bad week.
