L-3 Announces Fourth Quarter 2013 Results

NEW YORK, January 30, 2014 – L-3 Communications Holdings, Inc. (NYSE: LLL) today reported diluted earnings per share (diluted EPS) from continuing operations of $2.17 for the quarter ended December 31, 2013 (2013 fourth quarter), compared to $2.25 for the quarter ended December 31, 2012 (2012 fourth quarter). Net sales of $3.3 billion for the 2013 fourth quarter decreased by 9% compared to the 2012 fourth quarter.

“We performed well in the fourth quarter amid very challenging conditions caused by declining U.S. national security budgets and sequestration. We generated solid operating margin and cash flow despite declining sales,” said Michael T. Strianese, chairman, president and chief executive officer. “We also expanded our international and commercial business, which partially offset declines in our U.S. national security business. Our consistent and strong program execution, combined with cost take out measures, continues to drive our performance as we focus on growing in areas that align with our customers’ priorities.”

“Our acquisition in December of Mustang Technology Group, a developer and manufacturer of radar-based sensors and systems, adds important synergies, technologies and customers in our Electronic Systems segment. Mustang is another example of a niche acquisition that enhances L-3’s portfolio with innovative and disruptive products to grow our market share. We also continued to deploy our cash flow to increase shareholder value, with $444 million of cash returned to shareholders during the quarter and $1 billion for 2013, through repurchases and dividends.”

Key competitive contract wins for the quarter included: (1) a contract to design, manufacture and test Medium Range Ballistic Missile (MRBM) target launch vehicles and support equipment for the U.S. Missile Defense Agency (MDA), (2) a contract to design and develop a next generation transmission system for the U.S. Army’s Gemini Transmission program to modernize its ground combat vehicles, (3) a contract to provide network operations support to the U.S. Strategic Command for the Phoenix Air to Ground Communications Network (PAGCN) Contractor Logistics Support program, (4) a contract to design, build and install mission-critical shelters and electromagnetic shielding at the MDA’s Aegis Ashore site in Romania, and (5) a contract to provide Cathay Pacific Airlines full motion flight simulators and support for its Airbus 350 fleet.

L-3 Consolidated Results

Fourth Quarter Results of Operations:  For the 2013 fourth quarter, consolidated net sales of $3.3 billion decreased $304 million, or 9%, compared to the 2012 fourth quarter as lower sales to the Department of Defense (DoD) impacted each segment. Net sales to international and commercial customers increased 8%, or $73 million, to $970 million in the 2013 fourth quarter, compared to $897 million in the 2012 fourth quarter. Net sales to international and commercial customers, as a percentage of consolidated net sales, increased to 30% for the 2013 fourth quarter compared to 25% for the 2012 fourth quarter.

Operating income for the 2013 fourth quarter of $324 million decreased $40 million, or 11%, as compared to the 2012 fourth quarter. Operating income as a percentage of sales (operating margin) decreased by 20 basis points to 10.0% for the 2013 fourth quarter compared to 10.2% for the 2012 fourth quarter. The decrease in operating margin is primarily due to lower sales and higher severance costs. The 2013 fourth quarter included severance charges that reduced operating income by $11 million ($7 million after taxes, or $0.08 per diluted share) compared to severance charges of $6 million ($4 million after taxes, or $0.04 per diluted share) in the 2012 fourth quarter, reducing operating margin by 10 basis points. See segment results below for additional discussion of sales and operating margin trends.

Interest and other income, net, in the 2013 fourth quarter increased primarily due to a $2 million non-cash impairment charge recorded in 2012 for the dissolution of an unconsolidated joint venture.

The effective tax rate for the 2013 fourth quarter decreased to 29.4% from 31.7% for the same period last year. The decrease is primarily due to $8 million related to certain deferred tax benefits and $4 million for the U.S. Federal research and experimentation tax credit.

Net income from continuing operations attributable to L-3 in the 2013 fourth quarter decreased 8% to $196 million compared to the 2012 fourth quarter, and diluted EPS from continuing operations decreased 4% to $2.17 from $2.25. Diluted weighted average common shares outstanding for the 2013 fourth quarter declined by 4% compared to the 2012 fourth quarter due to repurchases of L-3 common stock.

Full Year Results of Operations:  For the year ended December 31, 2013, consolidated net sales of $12.6 billion decreased $517 million, or 4%, compared to the year ended December 31, 2012 as lower sales to the DoD caused by declining budgets, sequestration cuts and the continuing U.S. military drawdown from Afghanistan impacted each segment. Acquired businesses⁽¹⁾, which are all included in the Electronic Systems segment, added $81 million to net sales in the year ended December 31, 2013. Net sales to international and commercial customers increased 11%, or $341 million, to $3,461 million in the year ended December 31, 2013, including $74 million from acquired businesses, compared to $3,120 million in the year ended December 31, 2012. Net sales to international and commercial customers, as a percentage of consolidated net sales, increased to 27% for the year ended December 31, 2013 compared to 24% for the year ended December 31, 2012.

Operating income for the year ended December 31, 2013 of $1,258 million decreased $93 million, or 7%, as compared to the year ended December 31, 2012. Operating margin decreased by 30 basis points to 10.0% for the year ended December 31, 2013 compared to 10.3% for the year ended December 31, 2012. The decrease in operating margin is primarily due to higher design and production costs for the Command, Control, Communications, Intelligence, Surveillance and Reconnaissance (C³ISR) segment. Acquired businesses reduced operating margin by 10 basis points and higher pension expense of $11 million ($7 million after income taxes, or $0.08 per diluted share) reduced operating margin by 10 basis points. Additionally, the years ended December 31, 2013 and 2012 included severance charges that reduced operating income. In 2013, the severance charges were $29 million ($18 million after income taxes, or $0.20 per diluted share) compared to $23 million ($14 million after income taxes, or $0.14 per diluted share) for 2012. See segment results below for additional discussion of sales and operating margin trends.

Interest expense for the year ended December 31, 2013 declined by $7 million due to lower outstanding debt, which reduced interest expense by $21 million, partially offset by $14 million of interest expense that was allocated to discontinued operations in 2012. The increase in interest and other income, net, was primarily due to a $5 million non-cash impairment charge recorded in 2012 for the dissolution of an unconsolidated joint venture.

The effective tax rate for the year ended December 31, 2013 decreased to 28.2% from 32.2% for the same period last year. The decrease is primarily due to tax benefits in the year ended December 31, 2013 of: (1) $33 million ($0.36 per diluted share) for the U.S. Federal research and experimentation tax credit retroactively reinstated in 2013, of which $17 million ($0.19 per diluted share) relates to 2012, and (2) $8 million related to deferred tax benefits.

Net income from continuing operations attributable to L-3 in the year ended December 31, 2013 decreased 1% to $778 million compared to the year ended December 31, 2012, and diluted EPS from continuing operations increased 7% to $8.54 from $8.01. Diluted weighted average common shares outstanding for the year ended December 31, 2013 declined by 7% compared to the year ended December 31, 2012 due to repurchases of L-3 common stock.

Orders:  Funded orders for the 2013 fourth quarter were $3.0 billion, a decline of 11% compared to the 2012 fourth quarter. Funded orders for the year ended December 31, 2013 were $12.1 billion compared to $13.8 billion for the year ended December 31, 2012. Funded backlog declined 5% to $10.3 billion at December 31, 2013, compared to $10.9 billion at December 31, 2012.

Cash flow and cash returned to shareholders:  Net cash from operating activities from continuing operations increased by $107 million, or 20%, to $646 million for the 2013 fourth quarter, compared to $539 million for the 2012 fourth quarter. Net cash from operating activities from continuing operations increased by $32 million, or 3%, to $1,263 million for the year ended December 31, 2013, compared to $1,231 million for the year ended December 31, 2012. The increase in net cash from operating activities from continuing operations in both periods was primarily due to a decrease in working capital and reduced income tax payments and pension contributions. The table below summarizes the cash returned to shareholders during the 2013 and 2012 fourth quarter periods, and the years ended December 31, 2013 and 2012.

Reportable Segment Results

C³ISR

Fourth Quarter: C³ISR net sales for the 2013 fourth quarter decreased by $121 million, or 13%, compared to the 2012 fourth quarter. Sales decreased by $63 million for networked communication systems and $58 million for ISR Systems. The decrease in sales for networked communication systems was due to: (1) lower volume primarily for airborne and ground-based systems due to contracts nearing completion, declining demand caused by sequestration and other DoD budget reductions and the U.S. military drawdown from Afghanistan and (2) lower U.S. Army demand for remote video terminals primarily due to the U.S. military drawdown from Afghanistan. The decrease in sales for ISR Systems was primarily due to $39 million of lower volume for small ISR aircraft systems primarily due to the U.S. military drawdown from Afghanistan and $35 million of lower volume primarily for logistics support and fleet management services for U.S. Government customers. These decreases were partially offset by $16 million of higher volume on ISR platforms for foreign military customers.

C³ ISR operating income for the 2013 fourth quarter of $77 million, which included severance charges of $3 million, decreased by $15 million, or 16%, compared to the 2012 fourth quarter. Operating margin decreased by 40 basis points to 9.1%. Higher pension expense and severance charges reduced operating margin by 60 basis points. These decreases were partially offset by an increase of 20 basis points primarily due to improved productivity on certain contracts for ISR Systems.

Full Year: C³ISR net sales for the year ended December 31, 2013 decreased by $234 million, or 7%, compared to the year ended December 31, 2012. Sales decreased $208 million for networked communication systems and $26 million for ISR Systems. The decrease in sales for networked communication systems was due to: (1) lower U.S. Army demand for remote video terminals due to the U.S. military drawdown from Afghanistan, (2) lower volume primarily for airborne and ground-based systems and vehicle mounted satellite communication ground stations due to contracts nearing completion and declining demand caused by sequestration and other DoD budget reductions, and (3) lower productivity due to the implementation of new enterprise resource planning (ERP) systems during the third quarter, which caused sales volume to decline by $45 million. The decrease in sales for ISR Systems was primarily due to $154 million of lower volume for small ISR aircraft systems due to the U.S military drawdown from Afghanistan. This decrease was partially offset by $78 million of higher volume on ISR platforms for foreign military customers and $50 million of small ISR aircraft sales to the DoD.

C³ISR operating income for the year ended December 31, 2013 of $301 million, which included severance charges of $8 million, decreased by $63 million, or 17%, compared to the year ended December 31, 2012. Operating margin decreased by 120 basis points to 8.9%. Operating margin declined by: (1) 150 basis points primarily due to higher design and production costs for networked communication systems, (2) 60 basis points due to higher pension expense and severance charges, and (3) 30 basis points for higher costs and lower productivity due to the implementation of new ERP systems at networked communication systems. These decreases were partially offset by 70 basis points primarily due to improved productivity on certain contracts and 50 basis points due to sales mix changes primarily for ISR Systems.

Electronic Systems

Fourth Quarter: Electronic Systems net sales for the 2013 fourth quarter decreased by $133 million, or 8%, compared to the 2012 fourth quarter. Sales declined: (1) $69 million for Microwave Products primarily due to lower DoD demand for mobile and ground-based satellite communication systems, (2) $63 million for Precision Engagement due to declining DoD demand caused by sequestration primarily for ordnance and guidance products, and (3) $30 million for Simulation & Training due to reduced deliveries of U.S. Army rotary wing training systems for the Flight School XXI program. These declines were partially offset by $29 million of higher sales primarily for Marine & Power Systems due to the timing of deliveries of commercial shipbuilding products.

Electronic Systems operating income for the 2013 fourth quarter of $177 million, which included severance charges of $6 million, decreased by $15 million, or 8%, compared to the 2012 fourth quarter. Operating margin remained the same at 11.9% as improved contract performance across several business areas, including Space & Propulsion Systems and Microwave Products, was offset by sales declines and mix changes.

Full Year: Electronic Systems net sales for the year ended December 31, 2013 decreased by $153 million, or 3%, compared to the year ended December 31, 2012. Sales declined: (1) $140 million for Microwave Products due to reduced deliveries of power devices for commercial satellite communication systems and mobile and ground-based satellite communication systems for the U.S. military as programs ended, (2) $40 million for Space & Propulsion Systems due to certain funding constraints for the MDA’s air-launched target programs, (3) $39 million for Sensor Systems due to lower volume primarily for airborne EO/IR turrets for the U.S. Army Persistent Threat Detection System (PTDS) contract due to the U.S. military drawdown from Afghanistan, (4) $35 million for Security & Detection Systems due to lower orders from the Transportation Security Administration (TSA) caused by U.S. Government sequestration cuts and the completion of certain international contracts, and (5) $31 million for Precision Engagement primarily due to programs for ordnance products ending. These decreases were partially offset by a sales increase of $35 million primarily for Warrior Systems due to increased demand for holographic weapon sights for the commercial sporting and recreation markets and $16 million for Simulation & Training due to upgrades for F/A-18 flight simulator trainers and volume on new commercial aircraft simulation contracts. Sales also increased by $81 million primarily due to the Link U.K. and L-3 KEO acquisitions.

Electronic Systems operating income for the year ended December 31, 2013 of $645 million, which included severance charges of $19 million, decreased by $27 million, or 4%, compared to the year ended December 31, 2012. Operating margin decreased by 10 basis points to 11.7%. Sales declines and mix changes were mostly offset by improved contract performance across several business areas, including Space & Propulsion Systems and Microwave Products. Sales from acquired businesses reduced operating margin by 20 basis points.

Platform & Logistics Solutions (P&LS)

Fourth Quarter: P&LS net sales for the 2013 fourth quarter decreased by $13 million, or 2%, compared to the 2012 fourth quarter. Platform Solutions sales decreased by $31 million, which was partially offset by a sales increase of $18 million for Logistics Solutions. The Platform Solutions sales decrease was primarily due to lower volume for U.S. Navy maritime patrol aircraft resulting from reduced funding caused by the U.S. Government sequestration cuts and lower U.S. Air Force (USAF) Joint Cargo Aircraft (JCA) volume as the program nears completion, partially offset by Australia C-27J aircraft due to timing of contract deliverables. The increase in Logistics Solutions was primarily due to increased volume for field maintenance and sustainment services for USAF training aircraft driven by a new competitively won contract and U.S. Army C-12 aircraft.

P&LS operating income for the 2013 fourth quarter of $51 million, which included severance charges of $2 million, decreased by $6 million, or 11%, compared to the 2012 fourth quarter. Operating margin decreased by 80 basis points to 8.3% primarily due to lower margin sales mix for Logistics Solutions, partially offset by improved contract performance for Platform Solutions.

Full Year: P&LS net sales for the year ended December 31, 2013 decreased by $40 million, or 2%, compared to the year ended December 31, 2012 due to a sales decline for Logistics Solutions. Platform Solutions sales remained substantially the same as 2012. The decrease in Logistics Solutions was primarily due to the competitive loss of a task order for U.S. Army contract field team support services in Southwest Asia, which was completed in 2012, and reduced fleet management services due to the loss of the Joint Primary Aircraft Training Systems (JPATS) contract for the USAF. These decreases were partially offset by increased volume for field maintenance and sustainment services for USAF training aircraft and U.S. Army C-12 aircraft. For Platform Solutions, higher volume on USAF EC-130 and international head of state aircraft, and aircraft maintenance for the Canadian Department of National Defence was offset by lower volume for U.S. Navy maritime patrol aircraft and JCA, as well as reduced deliveries of aircraft cabin assemblies.

P&LS operating income for the year ended December 31, 2013 of $227 million, which included severance charges of $2 million, decreased by $9 million, or 4%, compared to the year ended December 31, 2012. Operating margin decreased by 20 basis points to 9.3% primarily due to the decrease in sales for Logistics Solutions.

NSS

Fourth Quarter: NSS net sales for the 2013 fourth quarter decreased by $37 million, or 11%, compared to the 2012 fourth quarter. The decrease in sales was primarily due to lower demand for a technical support contract for a U.S. Government agency due to U.S. Government sequestration cuts, and less demand for U.S. Special Operations Command (USSOCOM) information technology (IT) support services, as our previous single-award contract converted to several multiple-award contracts, which reduced our workshare.

NSS operating income for the 2013 fourth quarter of $19 million decreased by $4 million, or 17%, compared to the 2012 fourth quarter. Operating margin decreased by 50 basis points to 6.1%. Operating margin decreased by 140 basis points primarily due to lower sales and mix changes and 20 basis points due to the timing of award fees for intelligence support services. These decreases were partially offset by 60 basis points due to 2012 fourth quarter legal fees of $2 million related to a supplier dispute, which did not recur, 30 basis points for improved contract performance and 20 basis points due to lower operating costs.

Full Year: NSS net sales for the year ended December 31, 2013 decreased by $90 million, or 7%, compared to the year ended December 31, 2012 primarily due to reasons similar to those discussed above for the 2013 fourth quarter.

NSS operating income for the year ended December 31, 2013 of $85 million increased by $6 million, or 8%, compared to the year ended December 31, 2012. Operating margin increased by 90 basis points to 6.6%. Operating margin increased by: (1) 70 basis points due to legal fees of $5 million related to a supplier dispute and a $4 million inventory write-down of security and safety equipment in 2012, which did not recur in 2013, (2) 50 basis points due to lower operating costs, and (3) 40 basis points for improved contract performance. These increases were partially offset by 70 basis points primarily due to lower sales and mix changes.
