Renk's Valuation Gap Widens as Sector Storm Batters Defence Stocks, Analysts See Overreaction

Renk shares drop 20% YTD despite BlackRock raising stake to 4.44% and CEO contract extended to 2032. Analysts split on valuation discount vs peers.

The battle lines are drawn around Renk. On one side, a brutal sector sell-off has wiped nearly a fifth from the shares this year. On the other, two big institutional votes of confidence — a fresh stake from BlackRock and a long-term contract extension for the CEO — suggest the sell-off may have overshot. The result is a stock trading at a deep discount to defence peers, but still under pressure from macro headwinds.

The numbers tell the story of the week. On Wednesday, the shares closed at €43.99, marking a seven-day decline of 14.68% and a year-to-date loss of 20.28%. By Thursday, they had recovered slightly to €44.47, gaining 0.84% from the prior session, though still down 13.75% over the rolling week. The stock now sits 26.58% below its 200-day moving average.

The immediate trigger was the market’s reaction to Rheinmetall’s earnings call, which cast a pall over the European defence sector. Renk, despite its own solid operational performance, was caught in the downdraft. Analyst houses are now split on whether the punishment is justified.

BlackRock has added to its position in Renk, lifting its total stake to 4.44% from around 3.63%, with the crossing of the threshold recorded on 7 May. Directly held voting rights account for 2.95%, while another 1.49% is held via financial instruments, mostly securities lending. The move is not a classic strategic entry, but it signals institutional interest at a time when the shares are plumbing lows. Separately, the supervisory board extended CEO Alexander Sagel’s contract early, securing his leadership until March 2032 — a continuity play for a company whose project cycles span years.

The analyst community is offering contrasting takes. Goldman Sachs adjusted its estimates after Renk’s first-quarter 2026 results, cutting its price target from €70 to €65 while sticking with a “Neutral” rating. The bank still sees upside from current levels but no reason for greater optimism. MWB Research, on the other hand, upgraded the stock to “Buy” on 13 May with a €53 target, arguing the 20% post-Rheinmetall drop was overblown. The stock currently trades well below both targets.

MWB’s case rests heavily on valuation. The research house points out that Renk trades on a forward 2028 P/E of 16 and an EV/EBITDA multiple of 9, compared with 23 and 12 respectively for competitor Hensoldt. That valuation discount, MWB argues, looks excessive for a defence and drivetrain specialist with a predictable service business. The current level recalls the lower end of the IPO price corridor.

Central to Renk’s investment narrative is its aftermarket business. Spare parts and servicing are expected to generate roughly 50% of revenue through the 2030s, insulating the company from swings in new equipment orders. MWB projects strong growth ahead, forecasting 2028 revenue of €2.14 billion, EBITDA of €481 million, earnings per share of €2.63, and a dividend of €1.18.

With the shares at a substantial discount, the focus now shifts to management’s investor roadshow on 20 May. There, the leadership will need to deliver concrete details on order backlog, capacity utilisation, and margin plans — especially in the context of rising European defence budgets. After a brutal correction, Renk’s message of aftermarket stability and multi-year growth must compete with a market that has suddenly turned cautious on the sector.
