Peraso (PRSO) Q4 2025 earnings review
mmWave Ramps as Legacy Memory Fades, Bottom Line Stabilizes
Peraso successfully navigated a critical pivot in 2025, winding down its legacy memory IC business to focus entirely on its 60 GHz mmWave technology. While Q4 Total Revenue decelerated 22% YoY to $2.87M due to the memory phase-out, the core mmWave segment proved its viability with full-year revenue multiplying 6x over 2024. Profitability metrics improved significantly: rigorous expense control slashed the FY25 GAAP Net Loss by over half to $4.8M. However, the transition has removed a high-margin crutch, causing gross margins to compress sequentially. The company exits 2025 as a pure-play mmWave provider with expanding traction in Fixed Wireless Access (FWA) and defense, though its tight cash position and lack of forward quantitative guidance require investor caution.
🐂 Bull Case
Full-year mmWave product revenue grew 6x. The technology is rapidly securing design wins across distinct verticals (FWA, tactical defense, robotaxis) as legacy Wi-Fi and 5G spectrums become congested.
GAAP operating expenses dropped nearly 41% YoY to $11.8M in FY25. The leaner structure positions the company to reach breakeven much faster as high-volume mmWave production ramps up.
🐻 Bear Case
Gross margins are reversing. As high-margin end-of-life memory shipments dried up, Q4 gross margin compressed sequentially to 52.2% from 56.2%, forcing the mmWave segment to prove it can independently support the margin profile.
The company ended the year with just $2.89M in cash. While up slightly from Q3, it leaves minimal buffer for execution missteps, raising the likelihood of further dilutive equity raises.
⚖️ Verdict: ⚪
Neutral. The operational pivot is successfully executed, and mmWave demand is demonstrably accelerating. However, a sub-$3M cash balance, dropping gross margins, and the absence of clear quantitative guidance prevent a more bullish outlook.
Key Themes
Fixed Wireless Access (FWA) Market Leadership
Peraso is accelerating its position as a dominant supplier in the 60 GHz FWA market. The company cited a new design win and launch with MikroTik's next-generation 60 GHz wireless device. This builds on previous strategic wins with Tachyon Networks and WeLink, proving Peraso is successfully displacing legacy competitors based on performance and multi-gigabit throughput.
Tactical Defense Vertical Converting to Revenue
The military/defense market is transitioning from a pipeline opportunity into a tangible revenue driver. Management confirmed existing Israeli defense customer, InTACT, has officially selected Peraso's mmWave wireless technology for next-generation drone Identification Friend or Foe (IFF) systems. This validates the 'stealth' (low detectability) advantage of 60 GHz in mission-critical environments.
Macro Tailwinds: Wi-Fi and 5G Congestion
A clear macro driver has emerged: spectrum exhaustion. Management noted that conventional Wi-Fi and 5G solutions are failing due to oversaturation and interference in extremely high data rate applications. This structural bottleneck is directly pushing customers toward the unlicensed 60 GHz mmWave spectrum as an alternative.
Gross Margin Profile Reversing
A negative divergence appeared this quarter: while mmWave volumes increased, GAAP gross margins dropped sequentially from 56.2% in Q3 to 52.2% in Q4. Management explicitly blamed this on the reduction of memory IC shipments. This confirms that the legacy memory business was artificially inflating corporate margins, and the pure-play mmWave business currently commands a lower margin profile.
Cash Runway Limits Execution Flexibility
The balance sheet remains highly constrained. Total cash and cash equivalents stood at $2.89M at the end of Q4. While this represents a sequential improvement from Q3's $1.9M (likely aided by working capital movements or prior ATM facilities), it marks a decline from $3.34M a year ago. Operating an intensive semiconductor hardware business on less than $3M in cash leaves zero room for error.
Radio Silence on Strategic Review
In Q2 and Q3 2025, management explicitly highlighted an ongoing formal review of strategic alternatives (including a potential sale) initiated by an unsolicited offer. The Q4 release omits any mention of this process. The abrupt silence creates an overhang of uncertainty regarding ownership structure and long-term strategic direction.
Other KPIs
Accelerating improvement. Adjusted EBITDA improved from negative $4.5 million in FY24, reflecting the impact of aggressive cost containment. Q4 standalone Adjusted EBITDA was negative $1.1 million, stable compared to recent quarters but highlighting that the mmWave revenue base is not yet large enough to push the company into positive cash generation.
Decelerating YoY. Down from $14.6 million in FY24. This top-line contraction was entirely expected and engineered, resulting from the planned end-of-life shipments of legacy memory IC products, which masked the underlying 6x growth in the core mmWave portfolio.
Guidance
Stable. Management did not provide specific revenue or margin guidance for Q1 2026 or FY 2026, pivoting instead to a purely qualitative outlook. They cited 'growing market awareness' and a focus on broadening the customer base in FWA and tactical communications. This represents a deceleration in transparency, as previous quarters provided explicit next-quarter revenue ranges.
Key Questions
Strategic Alternatives Update
There was no mention of the formal strategic review process that was prominent in Q2 and Q3 following an unsolicited proposal. Has the board concluded this review, and what were the determinations?
Normalized Gross Margins
With the transition away from legacy memory ICs complete, what is the normalized, long-term gross margin target for the standalone mmWave product portfolio, and how do you plan to scale it back above the 55% threshold?
Capital Requirements
Given the ending cash balance of $2.89M, does the company project a need to utilize the At-The-Market (ATM) facility or seek other dilutive financing in the first half of 2026 to fund working capital for the ramping mmWave production?
