The call

Exasol's regulated-data niche keeps growing while overall revenue and headcount shrink, churn stays high, and its longtime tech chief just left unreplaced.

Exasol sells database software that runs on customers' own computers in Europe, designed for banks, hospitals, and government agencies that cannot store data on US cloud servers. The company has real customers in these regulated industries and is growing there, but its overall revenue is falling, customers are leaving faster than the company can replace them (20% yearly churn versus a 10-15% target), and free alternatives like ClickHouse and DuckDB can do similar work at lower cost. The critical question is whether churn drops below 20% in the next two quarters; if it does not, the company will struggle to survive as an independent business rather than being bought or shut down.

Why
01
AI pressure: AI coding agents (Copilot, Cursor) automating tuning of free engines like ClickHouse and DuckDB. AI agents can now auto-tune open-source ClickHouse/DuckDB, eroding the DBA-reduction edge Exasol used to sell. Could AI do the core job? Only partly.
02
Bigger players: Snowflake, Databricks, Google BigQuery, AWS Redshift, Microsoft Fabric sovereign-cloud SKUs. Hyperscalers now sell sovereign-cloud versions that copy Exasol's on-prem, air-gapped pitch to regulated clients. Could a giant copy it? Probably.
03
What protects it. EU sovereignty rules and air-gapped deployment needs that hyperscaler clouds still can't fully match.
What would change this call
Q2/Q3 2026 earnings show rolling 12-month ARR churn still above 20%. Focus-industry growth cannot offset broader customer exits, weakening the core moat.
No permanent CTO named by Q4 2026 after Golombek's June 2026 departure. Technology leadership vacuum persists during a critical product-repositioning period.
MariaDB Exa partnership produces no named customer bookings by Q3 2026. The US growth narrative built on this partnership fails to materialize.
Key numbers
  • ARR churn fell from 27% to 20% YoY (2026-03-31)
  • Focus-industry ARR grew 24% YoY, now 69% of total (2025-09-30)
  • 22-year CTO left June 2026, no successor named (2026-06-30)
Named risks
  • ARR churn still at 20% versus 10-15% guided target as of Q1 2026. Severity: high
  • CTO departed June 30, 2026 with no named permanent successor. Severity: high
  • Core revenue guided to decline mid-single-digits in FY2026 despite ARR growth claims. Severity: medium
  • Thinly traded small-cap stock with beta near 2.0 amplifies volatility on modest news. Severity: medium
  • Free open-source engines like ClickHouse and DuckDB erode pricing power in sovereign niche. Severity: high

Questions people ask
Is Exasol profitable in 2026?
Exasol guided FY2026 EBITDA of €3M to €4M as of May 7, 2026, but revenue is expected to decline mid-single-digits due to lapping a strong prior-year hardware quarter. Q1 2026 EBITDA was just €0.4M versus €1.3M a year earlier, so profitability remains thin and fragile.
Is Exasol losing customers?
Yes. Exasol's rolling 12-month ARR churn peaked at 27% in Q2 2025 and was still 20% as of Q1 2026 (May 7, 2026 report), well above management's 10-15% target, though churn is concentrated outside its finance, healthcare, insurance and public sector focus verticals.
Who owns Exasol and is it a takeover target?
Exasol AG is a publicly listed German company on Deutsche Börse (ticker EXL) with no controlling parent; Herald Investment Trust holds about 2.75% as of late 2024. Dr. Philipp Oberndorfer became Supervisory Board Chairman in June 2026, succeeding Volker Smid.
Could AI replace Exasol's database?
Not directly, since Exasol's SQL query engine role isn't substituted by LLMs, but AI coding agents are eroding its auto-tuning/DBA-reduction differentiator while free open-source engines like ClickHouse and DuckDB add competitive AI features, per company product releases through June 2026.
Is Exasol's biggest threat Snowflake or open-source databases?
Both, but differently: Snowflake, Databricks, BigQuery and Redshift dwarf Exasol in scale, while free self-hostable engines ClickHouse, DuckDB and StarRocks directly undercut its on-prem sovereign niche, per Exasol's own March 4, 2026 competitive comparison blog post.
Did the MariaDB partnership help Exasol grow in the US?
The MariaDB Exa partnership was announced October 22, 2025, aiming to reach MariaDB's over 1 billion download install base, but as of the July 21, 2026 evidence brief it had not yet materialized into named bookings, per management's own guidance commentary.
