Mercer International to restructure debt through prepackaged Chapter 11

What happened

Mercer International Inc. (Nasdaq: MERC), a pulp producer based in Vancouver, British Columbia, disclosed in a Form 8-K filed November 3, 2026 that it and one non-operating subsidiary entered into restructuring support agreements on November 2 with holders of its senior notes and holders of its common stock. The company said it intends to implement a comprehensive restructuring of its debt obligations and capital structure through a joint prepackaged plan of reorganization under Chapter 11 of the U.S. Bankruptcy Code, to be filed in the U.S. Bankruptcy Court for the Southern District of Texas, Houston Division.

The filing states that holders of approximately 85.3% of the principal amount of Mercer's 12.875% Senior Notes due 2028 and approximately 88.2% of its 5.125% Senior Notes due 2029, together about 87% of the senior notes, have committed to vote in favor of the plan. Holders of approximately 50% of Mercer's existing common stock have made the same commitment. Mercer said its operating subsidiaries will not commence Chapter 11 cases and will continue to operate normally, and that the debtors will operate as debtors-in-possession. The company said it expects to complete the restructuring by the end of calendar year 2026.

Under the plan as summarized in the filing, senior noteholders are expected to receive their pro rata share of 91.5% of the new common stock, 56.5% of $325.0 million of new convertible preferred stock, $150.0 million of takeback senior secured notes, and the right to participate in a $420.0 million rights offering of new money senior secured notes. Existing shareholders would receive 8.5% of the new common stock and 3.5% of the new convertible preferred stock, and their existing shares would be cancelled. General unsecured creditors are expected to be paid in full.

The filing sets milestones, including commencement of the Chapter 11 cases no later than November 9, 2026, a confirmation order within 45 days of the petition date, and a plan effective date no later than December 31, 2026.

The trading day

Mercer's shares closed at $0.21 on the event date, up 61.54% from the prior close of $0.13, according to the price data. Volume was 608,155,300 shares, about 144 times the average volume of 4,222,202. The filing does not address the share price move, and the sources provided do not establish why the stock traded as it did.

What this means

A Chapter 11 bankruptcy is a court-supervised process in which a company reorganizes its debts under the U.S. Bankruptcy Code. In a prepackaged case, the company negotiates the terms of that reorganization with major creditors and shareholders before filing, and those parties sign agreements — here, restructuring support agreements — committing to vote for the plan. That is what Mercer did: the filing says it has locked in support from holders of about 87% of its senior notes and about 50% of its stock before the case is even filed. This differs from a free-fall bankruptcy, where a company files first and negotiates with creditors afterward.

The instruments at the center of this are senior notes, which are corporate bonds. Mercer's 2028 notes carry a 12.875% annual coupon — the interest rate paid on face value — and mature in 2028; the 2029 notes carry a 5.125% coupon and mature in 2029. Under the plan, those bonds would not be repaid in cash at maturity but exchanged for a package of new securities: new common stock, new convertible preferred stock (preferred shares that can convert into common stock), takeback secured notes (new debt given to creditors in place of old debt), and the right to buy additional new notes in the rights offering.

A rights offering gives existing creditors the option to put new money into the company in exchange for new securities. Here noteholders can buy up to $420.0 million of new secured notes, and those who participate also receive a share of additional new common and preferred stock, called stapled equity. The filing says the rights offering is fully backstopped, meaning certain large noteholders have agreed to buy any portion other holders decline.

For current shareholders, the plan means their existing shares would be cancelled and replaced by a much smaller stake — 8.5% of the new common stock and 3.5% of the new preferred, before dilution from a management incentive plan and any conversion of the preferred. This is typical of Chapter 11: creditors rank ahead of shareholders, so equity usually receives only a residual share. Holders of 50% of the stock have already agreed to this treatment.

The Form 8-K itself is a current report companies file with the SEC to disclose material events between quarterly reports. Item 1.01 covers entry into a material definitive agreement (here, the restructuring support agreements), Item 7.01 is a Regulation FD disclosure, and Item 9.01 covers exhibits, which include copies of the agreements. The filing also notes commitments by the company not to pay dividends, repurchase stock or sell material assets outside ordinary business without consent of the required noteholders while the agreements are in effect.

The next steps are set by the milestones in the filing: the Chapter 11 filing by November 9, a disclosure statement and plan filed a day later, court approval of the disclosure statement within three days, and a confirmation order within 45 days of the petition date. The filing does not predict whether those deadlines will be met.
