Allegro (ALGM) Q4 2026 Earnings Transcript

Allegro MicroSystems reported strong fiscal Q4 and FY2026 results, with quarterly revenue up 26% year over year to $243 million and full-year sales up 23% to $890 million; FY2026 EPS more than doubled to $0.54. Gross margin improved to 50% in Q4 and 49.4% for the year despite a 200 bps gold cost headwind, while free cash flow reached a record $125 million and net debt fell to $116 million. Management guided Q1 FY2027 revenue to $245 million-$255 million and EPS to $0.19-$0.23, with data center sales expected to grow 20%-25% sequentially and remain a major driver.

Analysis

ALGM is transitioning from a cyclical auto sensor story into a content-expansion compounder, and the market is likely still underappreciating how much of the next leg is driven by mix rather than just unit growth. The key second-order effect is that data center is no longer a “nice extra” but a structurally higher-margin adjacency that can offset any pause in auto. As current-sensor attachment rises inside power supplies and backup units, the company’s revenue becomes less tied to server unit counts and more tied to architectural complexity — a better model for sustained upside.

The most important bull case is that gross margin should keep inflecting even without heroic top-line assumptions. Management is already signaling that fixed-cost absorption plus product mix can carry margins higher, while commodity mitigation and selective pricing create a second lever over the next 2-4 quarters. That matters because it turns every incremental dollar of revenue into disproportionate EPS upside, especially if data center and focused auto both remain above trend.

The main risk is timing mismatch: the market may be extrapolating the new data center runway too aggressively before isolated gate drivers contribute meaningfully. If AI server demand cools or customer qualification cycles extend, the stock can de-rate on a “great story, slow monetization” setup. The other near-term watch item is price/cost pass-through; if selective increases lag gold/freight pressure, Q1/Q2 margins could look good but not good enough to sustain current optimism.

Consensus appears to be missing that ALGM is increasingly a content winner in a few high-value sockets, not a broad-based semiconductor beta trade. That makes the name more resilient than a typical auto supplier during a weak macro patch, and it also means backlog and design wins should matter more than quarterly beats. I’d treat any post-earnings weakness as a chance to buy, provided the data center growth cadence and margin guide hold through the next quarter.

Key Decisions for Investors

• Long ALGM into the next 1-2 quarters on any pullback below the post-earnings range; thesis is margin leverage plus data-center mix, with 15%-20% upside if the market starts capitalizing FY27 EPS at a higher multiple.
• Pair trade: long ALGM / short a lower-quality auto-semi or industrial-analog basket over 3-6 months; ALGM has cleaner content expansion and less balance-sheet risk, while peers remain more exposed to macro unit softness.
• Buy ALGM Jan-2027 calls on a 1-2 week pullback; risk/reward favors optionality because isolated gate driver revenue is a 2027 story, but the stock can re-rate earlier on continued backlog and design-win commentary.
• If data-center revenue contribution rises above ~17%-18% of sales next quarter, add to long; that would confirm the mix shift is accelerating faster than consensus expects.
• Use a stop-loss on the long if management signals pricing offset delays or backlog conversion deterioration; that would imply the margin bridge is moving out by at least one quarter.
