Interdigital — Income Statement, Cash Flows & Balance Sheet
Is InterDigital profitable?
InterDigital delivered its strongest net income in at least three years, despite slightly lower revenue.
| 2024 | 2025 | Change | |
|---|---|---|---|
| Revenue | $868.5M | $834.0M | –4% |
| Total operating expenses | $429.0M | $373.2M | –13% |
| Income from operations | $439.5M | $460.9M | +5% |
| Net income | $358.6M | $406.6M | +13% |
| Operating margin | 50.6% | 55.3% | +4.7 pp |
Revenue dipped year-over-year, but that largely reflects timing — 2024 included an unusually large amount of "catch-up" revenue (back-payments from licensees covering prior periods). Underneath that, InterDigital cut licensing costs dramatically and expanded its operating margin to over 55%, translating to record net income.
A large one-time item inflated 2024 revenue and is worth understanding.
| 2023 | 2024 | 2025 | |
|---|---|---|---|
| Catch-up revenue | $141.2M | $460.1M | $277.4M |
| Total revenue | $549.6M | $868.5M | $834.0M |
| Catch-up as % of revenue | 26% | 53% | 33% |
Catch-up revenue — payments for past periods unlocked when new license agreements are signed — can swing significantly from year to year. More than half of 2024's revenue was catch-up; in 2025 it fell back but still made up about a third of the total. Investors should monitor the "recurring" portion of revenue separately from these one-time settlements.
Where does InterDigital's revenue come from?
Smartphones are the dominant and growing revenue driver; CE/IoT/Auto swung sharply lower.
| Segment | 2024 | 2025 | Change |
|---|---|---|---|
| Smartphone | $597.5M | $678.9M | +14% |
| CE, IoT/Auto | $268.7M | $154.6M | –42% |
| Other | $2.3M | $0.5M | –77% |
| Total | $868.5M | $834.0M | –4% |
The smartphone segment — InterDigital's core business — grew strongly and now accounts for about 81% of revenue. The CE/IoT/Auto drop reflects the timing of large Madison Arrangement settlements that boosted 2024 (gross Madison revenue fell from ~$210M to ~$42M year-over-year), not a structural decline in that market.
Does InterDigital generate cash?
InterDigital nearly doubled its operating cash flow, and free cash flow is substantial.
| 2024 | 2025 | Change | |
|---|---|---|---|
| Net cash from operations | $271.5M | $544.5M | +100% |
| Capitalized patent costs | ($52.9M) | ($54.6M) | +3% |
| Purchases of property & equipment | ($5.8M) | ($15.9M) | +174% |
| Free cash flow (approx.) | ~$212.8M | ~$474.0M | +123% |
The surge in operating cash flow was driven largely by a $118M swing in receivables collections. Free cash flow — cash from operations after reinvestment in patents and equipment — more than doubled, giving management significant flexibility for buybacks, dividends, and debt repayment.
How strong is InterDigital's balance sheet?
Liquidity is strong and growing, with cash and investments covering the primary debt maturity.
| 2024 | 2025 | Change | |
|---|---|---|---|
| Cash & equivalents | $527.4M | $739.0M | +40% |
| Short-term investments | $430.8M | $504.2M | +17% |
| Total liquid assets | $958.2M | $1,243.2M | +30% |
| 2027 convertible notes (principal) | $460.0M | $460.0M | — |
InterDigital holds well over $1.2 billion in cash and near-cash investments against its only significant debt — the 2027 convertible notes. The liquid cushion comfortably covers that obligation, and the notes are being converted early by some holders.
Shareholders' equity expanded sharply, even as the company returned capital aggressively.
| 2024 | 2025 | Change | |
|---|---|---|---|
| Total shareholders' equity | $857.2M | $1,101.1M | +28% |
| Share buybacks | $66.7M | $102.6M | +54% |
| Dividends declared per share | $1.70 | $2.60 | +53% |
Despite buying back stock and raising the dividend by 53%, equity grew by over $240M — a sign that earnings are outpacing capital returns. Approximately $127M remains under the existing buyback authorization.
