Grifols (BME:GRF) Stock Rallies As Q3 Earnings Leave Debt In Focus

Grifols stock closed at €11.23 on 3 November, capping a 30 day gain of about 17.8%. That is the short term story. The real drama sits on the balance sheet. Q3 2026 produced €2.04b in revenue and helped lift trailing 12 month earnings to €472m, yet interest expenses still weigh heavily and keep financial risk in focus.

Short term traders are reacting to the bounce. Longer term investors are eyeing the 16.2x P/E against the company’s internal discounted cash flow value and asking a different question: how much balance sheet strain are they willing to underwrite for that apparent discount?

Grifols earnings: execution milestones start to land

Bulls argue Grifols only works if execution tightens around plasma costs, margins and leverage.

"The main thing that has to go right is continued execution on plasma self sufficiency, cost discipline and debt reduction so that free cash flow and adjusted EBITDA margins stay aligned with the multi year targets management has set."

On this score, the latest quarter shows some concrete markers. Adjusted EBITDA reached €538m, with margin up 60 bps year on year, and management reiterated a 25% full year target. Free cash flow before M&A was €298m year to date, with conversion above 20%. Net leverage moved just below 4x after the redemption of €500m of higher cost debt.

Grifols bear case on regulation and cash still bites

Bearish investors argue Grifols is one regulatory setback away from stalling its cash engine.

"While free cash flow before M&A reached €468 million in 2025 and remained positive at €91 million in H1 2026, any reversal of this trend due to sustained regulatory disruption in Canada, ongoing albumin price pressure in China or higher compliance costs around plasma collection could stall deleveraging, keep interest costs elevated and weigh on future earnings quality."

Q3 figures show free cash flow pre M&A at €298m year to date and net leverage at 3.98x, so deleveraging is progressing. The risk is that albumin weakness in China is already visible and Canada collections remain paused, so the feared pressure points are present even as cash conversion improves.
