Insights

Large cash-and-stock acquisition with bridge financing, dilution and regulatory risk.

Martin Marietta plans to buy Lhoist North America for $13.5 billion, split between $7 billion cash and 10,953,543 new shares valued at $6.5 billion. This significantly expands its industrial minerals footprint while blending debt funding with equity issued to LNA Holding.

A $7.0 billion 364-day unsecured bridge facility from Goldman Sachs entities backstops the cash portion, but would temporarily raise leverage if drawn. LNA Holding is expected to own about 15% of Martin Marietta, with board representation and a two-stage lock-up, adding a sizable long-term shareholder.

The transaction depends on Hart-Scott-Rodino and other regulatory clearances by the October 31, 2026 long stop date, extendable to June 15, 2027. Failure to obtain approvals by the extended date in specified circumstances triggers a $350 million termination fee, highlighting execution risk around antitrust review and closing timing.

Expected post-deal stake Approximately 15% LNA Holding ownership of Martin Marietta after closing
Standstill cap 18% of outstanding shares Maximum ownership under standstill for LNA Holding and FGI
Securities Sale Agreement financial
"entered into a Securities Sale Agreement (the “SSA”) with LNA Holding"
Hart-Scott-Rodino Antitrust Improvements Act of 1976 regulatory
"conditioned upon the expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976"
lock-up financial
"subject to a lock-up period with respect to the Consideration Shares, with 50% of such shares released"
A lock-up is an agreement that prevents company insiders, early investors or employees from selling their shares for a set period after a public share offering. It matters to investors because it temporarily limits the number of shares available to trade—like a scheduled hold on extra inventory—and when that hold ends a large number of shares can enter the market, potentially putting downward pressure on the stock price and revealing insiders’ confidence in the company.
standstill obligation financial
"have agreed to be subject to a customary standstill obligation, including a restriction on acquiring shares"
registration rights agreement financial
"will enter into a customary registration rights agreement (the “Registration Rights Agreement”) in respect of the Consideration Shares"
A registration rights agreement is a contract that gives investors the option to have their ownership stakes officially registered with the government, making it easier to sell their shares later. This agreement matters because it provides investors with a clearer path to cash out their investments if they choose, offering more liquidity and confidence in their ability to sell their holdings when desired.
bridge loan facility financial
"a 364-day unsecured bridge loan facility in an aggregate principal amount of up to $7.0 billion"
A bridge loan facility is short-term financing that helps a company cover an immediate cash need while it arranges longer-term funding, like a temporary bridge spanning a river until a permanent road is built. For investors, it matters because it signals short-term liquidity pressure or planned transactions, can carry higher interest or fees, and may affect future equity or debt terms if the company must refinance, dilute shares, or accept tighter covenants.

Item 1.01. Entry into a Material Definitive Agreement.

 

Securities Sale Agreement

 

On June 27, 2026, Martin Marietta Materials, Inc., a North Carolina corporation (“Martin Marietta” or the “Company”) entered into a Securities Sale Agreement (the “SSA”) with LNA Holding SRL (“LNA Holding”), a société à responsabilité limitée organized under the laws of Belgium, pursuant to which Martin Marietta will acquire all of the outstanding equity interests in Lhoist North America, Inc. (“LNA”), a wholly-owned direct subsidiary of LNA Holding, that owns and operates the business of producing, distributing, marketing and selling lime, dolomitic lime, limestone- and dolomitic stone-based industrial minerals and products, and aggregates in North America (the “Transaction”).

 

Subject to the terms and conditions of the SSA, the consideration payable to LNA Holding at the closing of the Transaction (the “Closing”) will be $13.5 billion, consisting of (i) $7 billion in cash, subject to certain adjustments set forth in the SSA (the “Consideration Cash”), and (ii) 10,953,543 of newly-issued shares of Martin Marietta common stock, par value $0.01 per share (the “Consideration Shares”), with a value of $6.5 billion based on the volume-weighted average trading price of Martin Marietta common stock for the 15 trading days ending on June 26, 2026.

 

Each party’s obligation to consummate the Transaction is conditioned upon the expiration or termination of the applicable waiting period (and any extension thereof) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and the satisfaction or waiver of regulatory approvals and other customary closing conditions.

 

The SSA contains certain termination rights for Martin Marietta and LNA Holding, including the right of either party to terminate the SSA if the conditions to the Closing have not been satisfied (or waived) by October 31, 2026 (the “Long Stop Date”), subject to certain automatic extensions up to June 15, 2027 (the “Extended Long Stop Date”) that apply if, as of such time, the required regulatory clearances and the related condition that no law or order prohibit the Transaction have not yet been satisfied. If the SSA is terminated under specified circumstances relating to the failure to obtain the required regulatory clearances by the Extended Long Stop Date, Martin Marietta will be required to pay LNA Holding a termination fee of $350 million in cash.

 

The SSA contains customary representations and warranties of Martin Marietta and LNA Holding.  Additionally, the SSA provides for customary pre-closing covenants of each of Martin Marietta and LNA Holding.

 

The SSA will be filed to provide security holders with information regarding its terms. It is not intended to provide any other factual information about Martin Marietta, LNA Holding or LNA. The representations, warranties and covenants contained in the SSA were made solely for purposes of the SSA and as of specific dates, were solely for the benefit of the parties to the SSA, may be subject to limitations agreed upon by the contracting parties, including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties to the SSA instead of establishing matters as facts, and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to security holders. Security holders are not third-party beneficiaries under the SSA and should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of Martin Marietta, LNA Holding or LNA. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the SSA.

 

Shareholders Agreement

 

Following the Closing, LNA Holding is expected to hold approximately 15% of the outstanding Martin Marietta common stock based upon the outstanding shares of Martin Marietta common stock as of June 26, 2026. At the Closing, Martin Marietta, LNA Holding and, solely for purposes of the standstill provisions set forth therein, Financière de Gestions Internationales, a société en commandite par actions organized under the laws of Luxembourg (“FGI”), will enter into a shareholders’ agreement (the “Shareholders Agreement”). Under the Shareholders Agreement, LNA Holding and its affiliates will be subject to a lock-up period with respect to the Consideration Shares, with 50% of such shares released from the lock-up on the 12-month anniversary of the Closing and the remaining 50% of such shares released from the lock-up on the 24-month anniversary of the Closing. The Shareholders Agreement will further provide that the Board of Directors of Martin Marietta (the “Board”) will take such actions as are necessary to increase the size of the Board by one director, and LNA Holding will have the right to designate one director to the Board and to appoint one non-voting Board observer. These designation rights are subject to graduated reduction and termination based on LNA Holding’s beneficial ownership of Martin Marietta common stock (calculated on an as-converted basis): LNA Holding may designate one director and one observer for so long as it beneficially owns at least a fixed number of shares of Martin Marietta common stock to be set at the Closing to equal 10% of the issued and outstanding Martin Marietta common stock as of the Closing (calculated on an as-converted basis); this right is reduced to one director if such ownership falls below 10% but remains at or above a fixed number of shares of Martin Marietta common stock to be set at the Closing to equal 7.5% of the issued and outstanding Martin Marietta common stock as of the Closing (calculated on an as-converted basis); and all designation and observer rights terminate if such ownership falls below such fixed number of shares of Martin Marietta common stock to be set at the Closing to equal 7.5% of the issued and outstanding Martin Marietta common stock as of the Closing (calculated on an as-converted basis). Furthermore, subject to certain exceptions, in the event LNA Holding and its affiliates fail to vote all shares of Martin Marietta common stock beneficially owned by them in accordance with the recommendation of the Board (subject to certain exceptions) and in favor of persons nominated and recommended to serve as directors by the Board, all of LNA Holding’s designation rights will terminate.

 

In addition, FGI and LNA Holding and their affiliates have agreed to be subject to a customary standstill obligation, including a restriction on acquiring shares in excess of a fixed number of shares of Martin Marietta common stock to be set at the Closing to equal 18% of the issued and outstanding Martin Marietta common stock as of the Closing (calculated on an as-converted basis), which will be effective until the earlier of (a) 15 months after the date on which both (i) no LNA Holding designee sits on the Board and (ii) LNA Holding has irrevocably waived or no longer has any right to designate a director or observer and (b) the date on which LNA Holding holds fewer than the number of shares equal to a fixed number of shares of Martin Marietta common stock to be set at the Closing to equal 7.5% of the issued and outstanding Martin Marietta common stock as of the Closing (calculated on an as-converted basis).

 

 
 

 

Registration Rights Agreement

 

Pursuant to the SSA, Martin Marietta and LNA Holding will enter into a customary registration rights agreement (the “Registration Rights Agreement”) in respect of the Consideration Shares at Closing. The Registration Rights Agreement will provide for certain shelf, demand and piggyback registration rights for LNA Holding, subject to minimum offering sizes in certain cases, customary underwriter cutbacks, Martin Marietta blackout/suspension rights, and mutual indemnification rights and other customary requirements and conditions.

 

The foregoing descriptions of the SSA, form of Shareholders Agreement and form of Registration Rights Agreement are not complete and are qualified in their entirety by reference to the SSA, which is filed as Exhibit 2.1 hereto and is incorporated herein by reference.

Item 8.01. Other Events.

 

Bridge Commitment Letter

 

In connection with its entry into the SSA, Martin Marietta entered into a commitment letter, dated as of June 27, 2026 (the “Bridge Commitment Letter”), among Martin Marietta, Goldman Sachs Bank USA (“GS Bank”) and Goldman Sachs Lending Partners LLC (“GSLP” and, together with GS Bank, the “Commitment Parties”), pursuant to which the Commitment Parties committed to provide, subject to the terms and conditions set forth therein, a 364-day unsecured bridge loan facility in an aggregate principal amount of up to $7.0 billion (the “Bridge Facility”) to finance the Consideration Cash.

 

The commitments under the Bridge Facility are subject to reduction in equivalent amounts upon any incurrence by Martin Marietta of term loans and/or the issuance of notes in a public offering or private placement prior to the consummation of the Transaction and upon other specified events, subject to customary exceptions. The funding of the Bridge Facility is contingent on the satisfaction or waiver of customary conditions, including, without limitation, (i) execution and delivery of definitive documentation consistent with the Bridge Commitment Letter and (ii) consummation of the Transaction in accordance with the SSA. The commitments and agreements of the Commitment Parties under the Bridge Commitment Letter will terminate upon the first to occur of (a) the date on which definitive documentation with respect to the Bridge Facility has been executed and delivered, (b) the date of consummation of the Transaction, with or without the use of any portion of the Bridge Facility, (c) the termination of the SSA in accordance with its terms, (d) the reduction of the commitments under the Bridge Facility to zero and (e) 11:59 p.m., New York City time, on the date that is five business days following the later of (x) the Long Stop Date and (y) solely in the event that the Long Stop Date is extended in accordance with the SSA, the Extended Long Stop Date.

FAQ

What acquisition did Martin Marietta (MLM) announce in this 8-K?

Martin Marietta agreed to acquire Lhoist North America from LNA Holding for $13.5 billion. The target operates lime, dolomitic lime, limestone-based industrial minerals and aggregates businesses across North America, significantly expanding Martin Marietta’s presence in these product categories.

How is Martin Marietta (MLM) funding the $13.5 billion Lhoist deal?

The purchase price includes $7 billion in cash and 10,953,543 newly issued shares of Martin Marietta common stock valued at $6.5 billion. A $7.0 billion 364-day unsecured bridge loan commitment supports funding for the cash portion of the consideration.

What ownership stake will LNA Holding get in Martin Marietta (MLM)?

After closing, LNA Holding is expected to hold approximately 15% of Martin Marietta’s outstanding common stock, based on shares outstanding as of June 26, 2026. This stake comes from the 10,953,543 consideration shares issued as part of the transaction.

What governance rights does LNA Holding receive at Martin Marietta (MLM)?

Under a new shareholders’ agreement, LNA Holding can designate one director and one non-voting board observer initially. These rights step down or terminate if its beneficial ownership falls below share thresholds aligned with 10% and 7.5% of Martin Marietta’s outstanding stock.

Are the new Martin Marietta (MLM) shares issued to LNA Holding registered?

The consideration shares will be issued in an unregistered transaction, relying on Section 4(a)(2) of the Securities Act and/or Regulation S. A separate registration rights agreement will later give LNA Holding shelf, demand and piggyback registration rights for those shares.

What are the main regulatory and timing conditions for Martin Marietta’s deal?

Closing requires expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act and other customary regulatory approvals. Conditions must be satisfied by an initial October 31, 2026 long stop date, potentially extended to June 15, 2027.

What termination fee could Martin Marietta (MLM) owe if the deal fails?

If the securities sale agreement ends under specified circumstances tied to failure to obtain required regulatory clearances by the extended outside date, Martin Marietta must pay LNA Holding a $350 million cash termination fee. This fee directly links to regulatory-driven non-completion risk.
