Vertex (VERX) Q4 2025 earnings review

Retention Deteriorates as Growth Slips to Single Digits

Vertex delivered a mixed Q4 to close a turbulent year. While the company met its revised revenue targets and beat on profitability, the underlying health of the subscription base is showing cracks. Revenue growth decelerated to 9.1%—the first single-digit quarter in recent history—while Net Revenue Retention (NRR) compressed further to 105%. New CEO Christopher Young enters with a mandate to reverse these trends via AI and e-invoicing, but the guidance for 2026 implies only a modest recovery to ~10.5% growth.

🐂 Bull Case

Margin Expansion

Profitability remains a bright spot. Adjusted EBITDA margins expanded to 21.8% in Q4, and FY26 guidance ($188-192M) suggests further expansion to ~23%. The company is effectively balancing investments in AI with cost discipline.

E-Invoicing Tailwinds

Mandates in France and Germany remain a coiled spring for growth. Management cited 'accelerating growth' in the e-invoicing business during its first full year, positioning Vertex to capture the European compliance wave in late 2026.

🐻 Bear Case

Retention Bleed

Net Revenue Retention (NRR) dropped to 105% (down from 109% a year ago) and Gross Revenue Retention (GRR) slipped to 94%. This indicates Vertex is struggling to upsell existing customers and is seeing slightly elevated churn, a toxic combination for SaaS valuations.

Cloud Deceleration

Cloud revenue, the primary growth engine, slowed significantly to 23.0% YoY growth in Q4, down from ~30% in the prior three quarters. FY26 guidance assumes 25% cloud growth, suggesting the days of 30%+ expansion are over.

⚖️ Verdict: 🔴

Bearish. The sustained drop in NRR to 105% and the deceleration of Cloud revenue to 23% outweigh the modest EBITDA beat. Until the new CEO can prove that retention has bottomed, the growth narrative is compromised.

Key Themes

CONCERN🔴🔴

Retention Metrics Deteriorating

The most alarming trend in the report is the continued erosion of customer retention. NRR fell to 105%, a significant drop from 109% a year ago and 107% just last quarter. Furthermore, Gross Revenue Retention (GRR), which had been rock-solid at 95%, ticked down to 94%. This suggests the 'macro headwinds' cited in Q2 and Q3 are resulting in permanent customer loss or downsizing rather than just delayed expansion.

CONCERN🔴

Cloud Momentum Slowing

Cloud revenue growth is rapidly decelerating. After holding near 30% for most of FY25, growth dropped to 23.0% in Q4. While a portion of this is the law of large numbers, the drop is sharp. Guidance for FY26 forecasts 25% cloud growth, implying management expects a bounce back, but the exit velocity from Q4 makes that target look ambitious.

DRIVERNEW🟢

Leadership Transition to AI Focus

New CEO Christopher Young (ex-Microsoft, McAfee) presided over his first earnings call. His commentary heavily emphasized AI ('Smart Categorization') and workflow improvement. The strategic pivot is clear: Vertex aims to move beyond simple tax calculation into AI-driven compliance workflows to reignite growth.

DRIVER

European E-Invoicing Mandates

Management highlighted accelerating growth in the e-invoicing business. With mandates in France and Germany approaching in 2026/2027, this remains the company's most tangible catalyst for re-accelerating revenue. However, the benefits are back-loaded, while the costs are being incurred today.

THEME

Profitability Over Growth

Despite the topline pressure, Vertex is delivering on the bottom line. FY25 Adjusted EBITDA margins landed at 21.6%, and the company guided to ~$190M EBITDA for FY26 (approx. 23% margin). The company is successfully transitioning to a 'Rule of 40' profile, albeit heavily weighted toward profitability rather than growth.

Other KPIs

Annual Recurring Revenue (ARR)$671.0 million

Decelerating. Growth slowed to 11.3% YoY, down from 12.4% in Q3 and 16.1% in Q2. This is a lagging indicator confirming the slowdown in bookings observed throughout 2025.

Free Cash Flow (FY25)$47.6 million

Declining. Down from $77.7M in FY24. The drop is driven by increased CapEx ($96.2M vs $65.8M prior year) likely tied to software development and infrastructure for the new AI and e-invoicing initiatives.

Average Annual Revenue per Customer (AARPC)$137,867

Accelerating. Up 12.3% YoY and up sequentially from $133,484 in Q3. This is the one positive metric in the customer base—while they are retaining fewer customers (lower GRR), the ones that stay are getting larger, validating the enterprise-focused strategy.

Guidance

FY26 Revenue$823.5 - $831.5 million

Stabilizing. The midpoint implies ~10.6% YoY growth. This suggests 2026 will look very similar to 2025 (which ended at 12.2% growth but exited at 9.1%). Management is essentially guiding for a slight re-acceleration from the Q4 low point.

FY26 Adjusted EBITDA$188.0 - $192.0 million

Accelerating. Midpoint represents ~17% YoY growth in EBITDA dollars. Margin is expected to expand to ~22.9%, demonstrating continued operating leverage despite AI investments.

Q1 2026 Revenue$193.5 - $196.5 million

Decelerating. Implies ~10% YoY growth vs the prior Q1. While better than Q4's 9.1%, it confirms that a return to mid-teens growth is not imminent.

Key Questions

The NRR Floor

Net Revenue Retention has dropped 400 basis points in 12 months to 105%. Is this the bottom, or should investors expect further compression as the 'macro headwinds' cited in 2025 persist?

Cloud Growth Disconnect

Q4 Cloud growth slowed to 23%, yet guidance calls for 25% for the full year 2026. What specific pipeline developments or product launches give confidence that cloud growth will re-accelerate against tougher comps?

GRR Deterioration

Gross Revenue Retention dipped below the historical 95% floor to 94%. Is this driven by SMB churn (which management previously dismissed as minimal impact) or are enterprise customers effectively downsizing their contracts?

AI Monetization Timeline

With the launch of Smart Categorization and other AI tools, when does management expect these to become a material line item in ARR, rather than just a retention tool?
