NEWS RELEASE

LOEWS CORPORATION REPORTS NET INCOME OF

$394 MILLION FOR THE FIRST QUARTER OF 2019

NEW YORK, April 29, 2019—Loews Corporation (NYSE:L) today reported net income of $394 million, or $1.27 per share, for the three months ended March 31, 2019, compared to $293 million, or $0.89 per share, in the prior year period.

Net income for the three months ended March 31, 2019 increased from the prior year period due to higher earnings contributed by CNA Financial Corporation and Boardwalk Pipeline Partners, LP as well as higher parent company net investment income. These increases were partially offset by an income decline at Diamond Offshore Drilling, Inc.

Book value per share increased to $62.31 at March 31, 2019 from $59.34 at December 31, 2018. Book value per share excluding accumulated other comprehensive income (AOCI) increased to $63.59 at March 31, 2019 from $62.16 at December 31, 2018.

CNA’s earnings increased primarily due to higher net investment income and net investment gains. Returns on limited partnership and equity investments drove the increase in net investment income. Earnings in the 2019 period also increased due to a net retroactive reinsurance benefit under the 2010 loss portfolio transfer with National Indemnity as compared to a net retroactive reinsurance charge recorded in the 2018 period. Partially offsetting these increases was lower underwriting income reflecting higher catastrophe losses and lower favorable prior year development.

Diamond Offshore’s results declined due to continuing challenging market conditions. In addition, Diamond Offshore’s net income in 2018 included a benefit from a favorable adjustment to an uncertain tax position recorded at year-end 2017.

Boardwalk Pipeline’s operations improved due to higher earnings from firm transportation contracts mainly due to growth projects recently placed into service, partially offset by contract restructuring and expirations as well as lower storage and parking and lending revenues. The increase in net income contribution in 2019, however, is primarily the result of Loews now owning 100% of the company as compared to 51% in the prior year period.

Loews Hotels & Co’s earnings were consistent with the prior year period as improved operating performance from several owned hotels was offset by pre-opening expenses incurred at hotels under development and a charge related to the planned disposition of a property.

Income generated by the parent company investment portfolio increased primarily due to improved performance from equity securities.

At March 31, 2019, there were 305.5 million shares of Loews common stock outstanding.
