How Sonos Q4 Guidance Balances Revenue Growth Against Memory Inflation

Sonos, Inc. SONO enters the fourth quarter with improving revenue momentum and a much tougher profitability test. Third-quarter revenues rose 9% year over year to $375 million after 2% growth in the first half of fiscal 2026.

The fourth-quarter outlook keeps sales growth intact, but memory inflation is expected to create a much larger drag on gross profit and adjusted EBITDA. That tension puts the quality of growth at the center of the investment debate.

Sonos Q4 Revenue Guide Keeps Growth on Track

Sonos expects fourth-quarter revenues of $325 million to $355 million, implying reported growth of 13% to 23% year over year. The 14-week quarter includes an extra fiscal week expected to contribute about $24 million of sales.

Excluding that calendar benefit, management projects growth of 4% to 15%. The range still points to underlying year-over-year expansion despite the comparison being boosted by the extra week.

SONO Faces a $35 Million Memory-Cost Hit

Higher memory prices are expected to reduce fourth-quarter gross profit by about $35 million year over year. In the third quarter, higher memory costs reduced adjusted EBITDA by $14 million and gross margin by roughly 380 basis points.
GAAP gross margin is guided to 39% to 41%, with non-GAAP gross margin about 120 basis points higher. Adjusted EBITDA could range from an $11 million loss to an $18 million profit.

Sonos Margins Could Stay Pressured Into Fiscal 2027

The margin squeeze is unlikely to end with the fourth quarter. Management views the lower end of the 39% to 41% GAAP gross-margin range as a reasonable starting point for fiscal 2027.

The first half is expected to run lower before mitigation actions increasingly take effect. Sonos is working on supply, component costs and memory efficiency, but the benefits are expected to build progressively through fiscal 2027.

SONO Can Use Pricing but Risks Slowing Household Growth

Pricing remains available as a lever, yet Sonos is prioritizing new-household acquisition and notes that direct audio competitors have not materially raised prices on existing products. Faster price increases could therefore work against the goal of expanding its installed base.

Apple Inc. AAPL offers HomePod and HomePod mini speakers for the connected home. Amazon.com, Inc. AMZN markets Echo devices tied to Alexa, giving consumers additional voice-enabled speaker choices and adding to the competitive context around pricing and accessibility.

Sonos Has Liquidity to Absorb Near-Term Pressure

Sonos ended the third quarter with $206.9 million in cash and $54.1 million of marketable securities, for a combined $261 million. Operating cash flow totaled $144.2 million and free cash flow reached $127.5 million in the first nine months of fiscal 2026.

That liquidity supports product investment and margin-mitigation efforts. Inventory, however, stood at $158 million, up 37% year over year, increasing the cost of a demand miss or product-launch delay.

SONO Scores Support Growth but Flag Momentum Risk

Revenue growth remains on track, but the fourth quarter will test how much of that progress can reach gross profit while memory costs stay elevated. The near-term setup combines improving sales with unusually heavy margin pressure.

The stock currently carries a Zacks Rank #3 (Hold). You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.

It has a Growth Score of A, VGM Score of A, Value Score of B and Momentum Score of C. The A and B scores reflect more favorable characteristics than the C Momentum Score. Because Style Scores complement the Zacks Rank, the combination points to a mixed near-term profile rather than a stand-alone bullish signal.
