Lattice's Record Q2 Was Real-But at 896x Earnings, "Undervalued" Is a Dangerous Word

Record Q2 solved the operating question, not the valuation question

Lattice's second quarter confirmed that the turnaround is real. The company delivered record Q2 revenue of $201 million and non-GAAP EPS of $0.53, up 62% year over year and more than 120% year over year. But the stock now carries a Price-Earnings ratio of 895.63. At that level, the market is no longer paying for recovery; it is paying for sustained outperformance.

Shares also showed how quickly expectations moved. They rose 8.54% in the regular session before pulling back in after-hours trading. That kind of reaction suggests a market that likes the results but is already pricing in a high bar for the next quarter.

Rising estimates help the bull case, but they also raise the hurdle

Expectations are moving up with the stock. The 12-month consensus EPS estimate rose 11.65% over the last 30 days, with no negative revisions. That supports the bullish view, but it also means future upside likely requires another strong print or guidance beat.

The analyst backdrop cuts both ways. Lattice still has a Moderate Buy consensus, yet the average 12-month price target is $132.29, only modestly above recent trading levels. In other words, the stock still needs to earn another leg higher.

Lattice's operating momentum has a clear source

The stronger question now is whether the business can keep improving fast enough to justify the premium. So far, the trend looks structural rather than accidental.

Q1 showed the turnaround starting; Q2 extended it

In Q1, revenue grew 42.2% year over year, and adjusted EBITDA margin was already 39.6%. Q2 then accelerated, with revenue up 62% year over year. That progression matters because it suggests the recovery was building before the valuation became the main debate.

Compute & Communications is driving the mix shift

The clearest sign is segment mix. Lattice's Compute & Communications segment grew 83% year over year, indicating that demand is increasingly tied to AI-related infrastructure rather than to a broad cyclical recovery across all end markets. At the same time, Industrial & Embedded revenue grew 36% year over year, which suggests Lattice is not depending on only one growth lane.

Profitability is improving alongside revenue. Non-GAAP gross margin reached 71.7%, operating margin reached 38.3%, and free-cash-flow margin reached 40.4%. Operating cash flow also rose to $88.3 million from $50.3 million in Q1, while free cash flow increased to $81.3 million from $39.7 million. That points to better operating leverage as the business scales.

Supply remains the constraint, which supports visibility

Management said supply, not demand, is the primary constraint. It also highlighted accelerating backlog and strong design-win momentum. Taken together, those signals suggest better revenue visibility and a healthier setup for future estimate revisions.

The AMI acquisition, which closed at the end of July, could further broaden Lattice's platform and expand the opportunity over time. For now, though, the near-term test is straightforward: keep backlog converting, maintain margins, and continue hitting the high expectations the market has set.

Is Lattice still undervalued?

With earnings power rising quickly, "undervalued" is not the right default label. After a record quarter and a stock priced near 896x earnings, the better question is whether future growth can keep closing the gap between operating progress and valuation.
