InterDigital (IDCC) posted its third consecutive outsized quarter. Non-GAAP EPS of $3.11 beat the $1.96 consensus by 45.3% and cleared the $2.14 Earnings Whisper number by a wide margin. Revenue of $193.43 million topped the $156.94 million consensus by 23.3% and rose 17.5% from a year ago. Earnings Whispers measures earnings growth at 11.9%, well below the 22% increase the company reports against its own year-ago non-GAAP EPS of $2.55, so the improvement depends partly on which prior-year base investors use. The bigger story is the gap between a large one-quarter beat and a recurring-revenue base that is growing more slowly. That is the central tension.

The quality of the beat deserves scrutiny. Catch-up revenue, the one-time portion tied to past periods under new agreements, more than doubled to $36.2 million from $17.7 million, accounting for a meaningful share of the upside against guidance of $154-158 million. Smartphone revenue, still the core franchise, fell 10% to $122.6 million. Streaming and cloud contributed $15 million, down from $110 million in Q2, when an Amazon catch-up payment inflated results.

The beat was carried by consumer electronics, IoT and auto, which nearly doubled to $55.7 million on the new PC license and an EV-charging deal with KEBA. Adjusted EBITDA of $131.3 million, a 68% margin, crushed the $86-92 million guide. GAAP diluted EPS rose 21% to $2.34. On a nine-month basis, however, revenue and net income are still below 2025 levels, which included a heavier dose of catch-up payments.

The call preserved a credible growth story while exposing the deceleration. Annualized recurring revenue hit a record $629 million, up from $625.7 million in Q2 and $567 million in Q1. Year-over-year ARR growth, though, slowed to 7% from 13% in the first half and 24% in Q4 of fiscal 2025. Licensing now reaches about 70% of the PC market, covering 4 of the top 5 makers, up from roughly 50% after the HP deal.

Management also noted that PC and Amazon revenue are being recognized on conservative estimates pending arbitration. That leaves potential upside if those awards land favorably. Free cash flow jumped to $136.2 million from $66.6 million in Q2. The company repaid $83.2 million of debt through early conversions and raised the quarterly dividend 7% to $0.75.

Guidance is where the setup gets more complicated than the surprise implies. Full-year targets moved up modestly, and they are based only on existing contracts:

• adjusted EBITDA of $507-515 million, versus a prior midpoint of $499 million;
• non-GAAP EPS of $11.99-12.25, versus a prior midpoint of $11.83;
• revenue of $813-819 million, above the prior $810 million midpoint.

The Q4 outlook is more muted. Revenue guidance of $154-160 million implies an adjusted EBITDA margin near 54%, well below Q3. That fits the in-line characterization of the guide, and any new deals would be additive. Enforcement costs remain elevated with no near-term relief expected.

The catalyst slate is rich. InterDigital won two more Unified Patent Court injunctions against Disney, bringing its record to 8 for 8 in decided cases, and secured a preliminary injunction against TCL in Brazil. The Lenovo arbitration decision is expected by the first half of 2027, and VVC codec adoption by Qualcomm, MediaTek and Android points to a longer-dated royalty lever. Bears have legitimate ammunition, though. Disney is attempting a VP9 codec workaround, with a new case set for a December hearing, and two smartphone vendors, including Transsion, remain unlicensed with uncertain timing.

Investor sentiment was essentially unchanged heading into the report, edging from 0.1017 to 0.1071, which is mildly positive rather than euphoric. The stock reflects the same restraint. Shares were up 4.1% since the open following the July report and sat just 0.9% above the 200-day moving average. They were also about 9.9% below the September 11 inter-earnings high of $355.69, having given back a good part of the post-Q2 run. Price and momentum trend readings are positive, while the AVWAP trend remains negative.

The bottom line is that InterDigital delivered another decisive beat, expanded its licensing footprint beyond smartphones, and raised full-year targets using contracted revenue alone. Much of the upside, however, came from catch-up payments, ARR growth is slowing, and Q4 guidance resets margins lower. The next leg of the story depends on arbitration outcomes, the Disney and TCL enforcement campaigns, and converting the remaining smartphone holdouts into recurring revenue.
