Commerzbank Faces Two Defining Tests as Takeover Deadline and Strategy Targets Collide

Frankfurt prosecutors open probe into market manipulation as Commerzbank and UniCredit clash over tender results; upgraded strategy seeks to defend independence.

Frankfurt prosecutors have stepped into the battle for Commerzbank, opening a probe into suspected market manipulation just as the final deadline for UniCredit’s takeover bid arrives on 3 July 2026. The investigation centres on an extraordinary surge in securities lending – volumes have jumped tenfold since the Italian lender launched its offer. The bank has pointed to possible links with institutions close to UniCredit, escalating the tension around the outcome of the tender.

At the heart of the dispute is a stark disagreement over how many independent shareholders have actually tendered their shares. UniCredit reported roughly 12.5% of shares were offered after the regular deadline in mid-June, but Commerzbank’s own calculation paints a very different picture. According to the Frankfurt-based lender, 11% of those came from other banks and only just over 1% from institutional investors, with retail investors accounting for a mere 0.05%. The board argues that genuine independent investors contributed little more than 1%, a figure that, if confirmed by the authorities, would seriously undermine the legitimacy of UniCredit’s approach.

Commerzbank is not relying solely on legal arguments to defend its independence. In May, the bank sharpened its “Momentum 2030” strategy, lifting financial targets for 2026, 2028 and 2030 after a strong start to the year. The first quarter delivered a notably higher operating result, an improved net profit and a rising net return on equity, underpinned by growing revenues and better efficiency. The private and business customer segment in Germany performed particularly well, while corporate lending saw solid expansion. The strategy also promises a payout ratio of 100% until the hard core capital ratio reaches 13.5%, making the stock attractive for income-focused investors.

The market has already priced in much of the takeover premium. At €37.75, the shares are just 2.83% below their 52-week high of €38.85, having gained 37.07% over the past twelve months. They trade comfortably above the 50-day moving average of €36.52 and more than 10% above the 200-day line at €34.21, both signs of a healthy uptrend. Yet the high annualised volatility of 22.50% – and an RSI of 57.1, which suggests neither overbought nor oversold – underscores the uncertainty.

The bullish narrative rests on the bank’s ability to deliver on its upgraded efficiency targets while navigating a tricky macroeconomic environment. Falling interest rates could pressure net interest income, though that line held steady in the first quarter despite lower rates. The costs of digital transformation, particularly investments in artificial intelligence, could also weigh on profitability in the near term, even if they are designed to cut costs later. The bank kept overall costs flat in the first quarter, which shows discipline, but sustaining that while funding new technology remains an open question.

UniCredit remains the dominant single shareholder with about 42.5%, and any legal proceedings are unlikely to conclude before 2027. The next two weeks will be critical: on 8 July, UniCredit will publish the final acceptance tally, and in August, Commerzbank will release its second-quarter interim report. A low independent tender could force the Italians to rethink their strategy, but a disappointment there might also drain the speculative froth from the stock. If the share price slips below the 50-day support at €36.52, the current uptrend would come under pressure, with the 200-day line at €34.21 acting as the next floor.

The bank’s own progress will also be judged against its raised targets. The next scheduled check comes with the third-quarter report later this year. For now, Commerzbank is fighting on two fronts – in the courtroom and on the balance sheet – and the outcome of either will shape whether the stock can break out to new highs or retreat from its recent gains.
