Summary
CS Disco reported fourth quarter revenue of $41.2 million, up 11.3% from the prior-year quarter. Full-year revenue was $156.8 million, up 8.3%. Gross profit rose 12.7% to $30.9 million in the quarter, and full-year gross profit rose 9.3% to $117.4 million. Gross margin was 75.1%, up 0.9 percentage points. Full-year gross margin was 74.9%, up 0.7 percentage points. The company still posted a quarterly operating loss of $9.2 million, but that loss narrowed 64.6% from the prior-year quarter. Net loss narrowed 66.3% to $8.5 million. For the full year, operating loss narrowed 22.0% to $48.1 million, and net loss narrowed 20.4% to $44.4 million. Full-year diluted EPS was -$0.72, up 22.6%. Operating margin was -22.4%, up 48.2 percentage points. Full-year operating margin was -30.7%, up 11.9 percentage points.
Cash generation remained uneven. Operating cash flow was $0.8 million in the fourth quarter, down 63.5% from the prior-year quarter. For the full year, operating cash flow was -$14.9 million, down 70.7%. Capital expenditures were $0.5 million in the quarter, down 9.1%, and $3.1 million for the full year, up 9.8%. Deferred revenue was $5.4 million, up 25.6%. Remaining performance obligations were $23.1 million, down 15.4%. Adjusted EBITDA, a non-GAAP measure, was -$2.2 million in the quarter, compared with -$4.3 million in the prior-year quarter. Full-year Adjusted EBITDA was -$10.2 million, compared with -$18.7 million.
Operational metrics showed mixed momentum. DISCO ended 2025 with 1,549 customers, up from 1,478 at the end of 2024. Large customers, defined as those with more than $100,000 in revenue over the previous 12 months, rose to 330 from 315. Large customers accounted for approximately 76% of revenue for each year. The dollar-based net retention rate was 98% as of December 31, 2025, up from 96% a year earlier. Usage-based revenue represented 91% of total revenue in 2025, up from 89% in 2024, while subscription revenue fell to 9% from 11%. Less than 10% of revenue was generated outside the United States in 2025. The company also announced an agentic AI tool for fact investigation and eDiscovery, and a new commercial model that bundles DISCO Ediscovery, DISCO Case Builder, and the Cecilia AI platform for one per gigabyte rate.
Guidance points to a softer first quarter but a return to growth for the full year. For the first quarter of 2026, DISCO expects Adjusted EBITDA of -$6.0 million to -$4.0 million. For the full fiscal year 2026, the company guides Adjusted EBITDA of -$8.5 million to -$4.5 million. Risks include a history of operating losses, dependence on customer usage, and the timing of large legal matters. The company also faces macroeconomic uncertainty, tariffs, and legal industry pressures. Executive orders against certain law firms could restrict their federal practice, and decreased federal enforcement or government shutdowns could delay litigation and reduce usage. Competition, the ability to add customers, expand sales coverage, grow internationally, and maintain data security are additional risks.

Risks
MD&A and risk factors highlight that executive orders issued by President Trump against certain law firm partners, decreased federal agency enforcement, and potential U.S. government shutdowns could reduce the volume of major legal matters and therefore customer usage. The company had not observed adverse revenue impact as of the filing, but uncertainty remains.
Large customers, defined as those with revenue over $100,000 in the previous 12 months, accounted for approximately 76% of revenue for each of the years ended December 31, 2025 and 2024. A limited number of customers represent a substantial portion of revenue, so failure to retain them could significantly reduce revenue.
Revenue is usage-based and depends on the timing, duration, and scope of customers' legal matters, with no long-term contractual commitments for most customers. MD&A states operating results have fluctuated significantly with the inception and conclusion of large legal matters, especially for DISCO Review.
The company has incorporated generative AI into products and operations, including the Cecilia ediscovery chatbot, and faces risks from operational challenges, flawed or biased AI outputs, data leakage, and evolving AI regulations such as the EU AI Act. Failure to keep pace with AI developments could make offerings less competitive.
The company processes highly sensitive legal documentation for law firm and corporate customers, and risk factors note past unsuccessful phishing attempts and a shared responsibility model where customer misconfiguration can still harm reputation and revenue. A security incident could lead to regulatory actions, litigation, and loss of customers.
Stringent and evolving privacy laws, including EU GDPR, UK GDPR, CCPA, and a U.S. Department of Justice rule on sensitive personal data, impose compliance costs and potential fines up to 4% of annual global revenue. Cross-border data transfer restrictions could interrupt operations.
The company outsources substantially all cloud infrastructure to Amazon Web Services, and the AWS agreement has no obligation to renew on commercially reasonable terms. Any disruption, capacity limitation, or cost increase could harm operations and require expensive migration.
Net cash used in operating activities was $14.9 million for the year ended December 31, 2025, an increase of $6.2 million from $8.7 million used in the prior year. The company may need additional capital, and financing may not be available on favorable terms.
Risk factors state that although revenues have increased year over year, the rate of revenue growth has declined from prior periods and may continue to decline. MD&A reports revenue grew 8% for the year ended December 31, 2025, and dollar-based net retention was 98%.
A September 2023 purported stockholder class action remains pending, and the company has agreed to settle it without admission of liability subject to court approval. General and administrative expenses increased 19% for the year ended December 31, 2025, partly due to $7.4 million in professional services costs primarily related to legal fees and a legal loss contingency accrual.
The company will cease to qualify as an emerging growth company as of December 31, 2026, which will require auditor attestation of internal control over financial reporting and increase legal and financial compliance costs. It may also no longer qualify as a smaller reporting company.
Future success depends on recruiting, training, and retaining sufficient qualified developers, sales, and marketing personnel. MD&A notes plans to enhance sales force headcount and expand globally, and failure to retain key personnel could impair growth.
Net operating loss carryforwards may be limited by Section 382 ownership changes and expiration, and international operations may face transfer pricing challenges. The One Big Beautiful Bill Act enacted in July 2025 could also affect the effective tax rate.
