Morgan Stanley Downgrades Mondi to Underweight Amid Valuation Concerns, Shares Drop

Morgan Stanley shook up the market view on Mondi (LSE: MNDI) by downgrading the stock to "underweight" from "equal weight," sparking a more than 3% slide in its shares on Monday. The investment bank pointed to a dangerously high valuation and murky earnings ahead as the main culprits behind the shift.

Margins have taken a hit at Mondi, dropping below levels not seen since the global financial crisis. Morgan Stanley has responded by cutting its earnings estimates and anticipates EBITDA will dip again in 2026 compared to 2025. To put numbers on it, their forecast predicts Mondi's EBITDA will clock in at €958 million next year, well short of the €1.13 billion consensus.

The 2026 EBITDA forecast puts the stock's enterprise value-to-EBITDA multiple at roughly 8.3 times, marking a 20% premium over the company's historical average of 7.2 times. That premium contributed heavily to the downgrade.

Market headwinds across Mondi's final product lines complicate matters further. Morgan Stanley noted ongoing subpar operating rates across all grades and soft demand stretching back to 2022, a reflection of cautious consumers.

With little hope for a swift change in supply-demand equilibrium, Morgan Stanley's outlook extends 12 to 18 months with no material pickup expected. The firm also warns that the current earnings run could disappoint by about 30% versus consensus for next year.

While projections do assume a better second half of 2026 compared to the first, risks still tilt toward further downside. The combination of squeezed margins, weak market sentiment, and a valuation premium paints a cautious picture.

This fresh warning for Mondi reminds us that elevated multiples can become a choke point when earnings stumble. The rough road ahead for EBITDA sketches a meaningful check on optimism.

Meanwhile, traders saw the immediate impact as shares fell sharply on the day. Whether this signals a longer-term shift or just a pause amid market noise remains an open question.
