SUPPLEMENT TO THE PROXY STATEMENT FOR
THE SPECIAL MEETING OF COMMON UNITHOLDERS OF TEEKAY LNG PARTNERS, L.P.
TO BE HELD ON DECEMBER 1, 2021
As previously disclosed, on October 4, 2021, Teekay LNG Partners L.P., a Marshall Islands limited partnership (the
Partnership), entered into an Agreement and Plan of Merger (as it may be amended from time to time, the Merger Agreement) with Stonepeak Limestone Holdings LP (f/k/a Stonepeak Infrastructure Fund IV Cayman (AIV III) LP), a
Cayman Islands exempted limited partnership (Parent), Limestone Merger Sub, Inc., a Marshall Islands corporation and wholly-owned subsidiary of Parent (Merger Sub), and Teekay GP L.L.C., a Marshall Islands limited liability
company and the general partner of Teekay LNG (the General Partner), relating to the proposed acquisition of the Partnership by Parent. Pursuant to the terms of the Merger Agreement, Merger Sub will merge with and into the Partnership
(the Merger), with the Partnership continuing as the surviving entity of the Merger as a wholly-owned subsidiary of Parent.
In connection with the Merger, the Partnership furnished a proxy statement and form of proxy card on Form 6-K, dated November 2,
2021 (the Proxy Statement), to the U.S. Securities and Exchange Commission (the SEC) with respect to the special meeting of the common unitholders (the Special Meeting) of the Partnership (the Common
Unitholders) to be held on December 1, 2021, at 1:00 p.m., Atlantic Time, at Conyers Dill & Pearman Limited, Clarendon House, 2 Church Street, Hamilton HM 11, Bermuda. At the Special Meeting, the Common Unitholders will be asked
to, among other things, consider and vote on the Merger Agreement and the Merger.
Since the announcement of the Merger, a lawsuit has
been filed by a purported Common Unitholder of the Partnership. The lawsuit was filed on November 18, 2021 in the United States District Court for the Southern District of New York and is captioned Sams v. Teekay LNG Partners L.P., et
al., No. 1:21-cv-09572. The lawsuit names the Partnership and members of the General Partners board of directors as defendants. The plaintiff alleges, among other things, that the defendants violated Sections 14(a) and 20(a) of the
Exchange Act, because the Proxy Statement allegedly omits material information with respect to the proposed Merger and is therefore false and materially misleading. The plaintiff seeks, among other things, injunctive relief, distribution of an
amended Proxy Statement addressing the alleged disclosure deficiencies, and an award of attorneys fees and expenses. Although the lawsuit alleges a violation of Section 14(a) of the Exchange Act, as a foreign private issuer
under SEC rules, the Partnership is not subject to such Section. Additional lawsuits may be filed relating to the Proxy Statement or the Merger prior to the anticipated closing of the Merger. In addition, the Partnership has received a letter, dated
November 12, 2021, on behalf of another purported Common Unitholder, which makes similar demands.
The Partnership and the other
defendants vigorously deny that they have committed any violation of law or engaged in any of the wrongful acts that are or could have been alleged in the lawsuit and demand letter described above, or in any similar lawsuits that may subsequently be
filed, and expressly maintain that they diligently and scrupulously complied with their fiduciary and other legal duties. The Partnership and the other defendants (a) deny that any of the disclosures in the Proxy Statement identified in
the lawsuit or the demand letter are materially deficient, (b) deny that any further disclosure is required to supplement the Proxy Statement under any applicable rule, statute, regulation or law, and (c) deny and do not believe that any
of them has committed any violation of law. However, solely to avoid the potential expense and distraction associated with these meritless claims, the Partnership is providing herein certain additional disclosures that are supplemental to those
contained in the Proxy Statement. Nothing in these supplemental disclosures shall be deemed an admission of the legal necessity for, or materiality under any applicable laws of, any of the additional disclosures set forth herein, in the Proxy
Statement.
It is possible that additional, similar lawsuits may be filed, that the lawsuit described above may be amended, or that the
Partnership or the General Partners directors may receive other demands. If this occurs, the Partnership does not intend to announce the filing or receipt, as applicable, of each additional, similar complaint, amended complaint or demand
letter unless it contains materially new or different allegations.
