The Software Engine The Broadcom Stock Bears Overlook

While Wall Street obsesses over AI chip sales, a different, high-margin business is providing the stability that could answer the biggest risk.

If you follow Broadcom (AVGO), you know the story is about artificial intelligence. The numbers are almost hard to comprehend, with AI semiconductor revenue growing and bookings that give the company visibility years into the future. After its 60.1% run over the last year, it’s clear the market has priced in a lot of that success.

But that growth comes with a catch: margin pressure. As the mix of revenue shifts toward custom AI chips, which carry lower gross margins, the company’s profitability may erode. This is where you need to look past the headlines to a different part of the business and to one number that reframes the entire risk-reward equation.

A High-Margin Foundation

The metric that matters is the 17% year-over-year growth in annual recurring revenue, or ARR, from its infrastructure software segment. That figure isn’t just a sign of healthy demand; it’s evidence of a steady, predictable engine humming beneath the more cyclical chip business. This segment is no small matter, accounting for $7.2 billion in the last quarter, or 32% of total revenue.

More importantly, it operates at a completely different level of profitability. In the second quarter, the software business posted an operating margin of approximately 79%. For comparison, the much-lauded Semiconductor Solutions segment had an operating margin of 62%. That gap is the quiet strength in the Broadcom story.

The Ballast For The AI Boom

This brings us back to the central worry. As the company sells more custom AI silicon, won’t overall profitability suffer? Management itself guided for consolidated gross margin to decline to approximately 74% in the next quarter, acknowledging the impact of this mix shift. This is precisely where the software business becomes so crucial.

Its large, recurring, and high-margin revenue base provides the operating leverage to absorb that pressure. It is the key reason management can forecast a stable consolidated operating margin of 67%, even as the gross margin feels the squeeze. The software segment acts as a ballast, providing stability against the very risk the AI boom creates. It’s the anchor that allows the company to ride the AI wave without being swamped by it.

So while the market rightly focuses on the high demand for AI chips, the story of Broadcom’s durability may lie in its less-discussed software business. The thing to watch is simple: as long as that software ARR continues to grow and its margins remain robust, it provides an answer to the biggest question hanging over the stock.

But What If We Are Wrong?

Here is the honest part. Even a well-evidenced case can be wrong, and even when the thesis is right, the timing can be early. The best investors in the world misjudge single stocks and single moments all the time, because no one number, however compelling, controls how one company performs from here.

That is exactly why durable wealth is rarely built on individual bets. It is built on a disciplined, rule-based process across a basket of quality businesses, where being wrong on any one name barely dents the whole. The Trefis High Quality (HQ) Portfolio takes that approach. It holds 30 high-quality stocks and re-balances them with discipline, so no single name carries an outsized share of your outcome, and it has a track record of outpacing the S&P 500, S&P Mid-cap, and Russell 2000. If you find a number like the one above worth acting on, a rules-based home for that kind of quality is worth a serious look.
