ABB Q1: Revenue growth, improved profitability

·                                Improved portfolio and geographic balance generates solid results in a mixed market

·                                Revenues steady to higher in all divisions(1); Thomas & Betts on track

·                                Operational EBITDA(2) and margin higher, continued solid execution on cost savings

Zurich, Switzerland, April 24, 2013 — ABB today reported its first-quarter 2013 results, highlighting revenue growth and improved operational profitability2 despite a weak business environment.

“Given the continued uncertainties in the global economy, this is a satisfactory start to 2013,” said ABB Chief Executive Officer Joe Hogan. “We continued to execute well, successfully balancing solid cost discipline with targeted growth in businesses and regions where we have competitive advantages, especially in areas like industrial efficiency, power reliability and renewable energy.

“Our balanced portfolio and global footprint contributed to the resilient performance, allowing us to find and capture growth opportunities in a mixed market. For example, we won some key orders in marine, mining, and robotics, and increased emerging market orders by 10 percent. We lifted total revenues on both an organic and inorganic basis.

“Our execution on cost remained strong, with tight discipline on G&A expenses,” Hogan said. “Continued success in sourcing and productivity improvements saved us about $260 million.

“The Thomas and Betts integration and synergies are on track. We’re very pleased with this acquisition and the improved balance it gives us in the North American market.

“The Power Products team turned in another good performance, with an operational EBITDA margin of 14.9 percent, again within our guidance of 14.5 to 15.0 percent range for the full year, thanks to solid execution on cost and selective growth initiatives in more profitable end markets.

“We achieved these results despite continued demand headwinds,” Hogan said. “Growth in the US decelerated further in the quarter and industrial investments in much of Europe remained mixed. Cash flow was lower than we’d like, but it was largely expected and mainly reflects the timing of project execution, so we expect to see that recover over the coming quarters.

“For the rest of the year, we’ll continue to focus on the cost-growth balance. Macroeconomic indicators remain unclear, which makes it tough to predict how the early-cycle businesses will perform. However, our strong order backlog will help mitigate some of that uncertainty, and we’re confident that our better balance across businesses and regions will continue to provide us with profitable growth opportunities.”

Summary of Q1 results

Growth overview

Market conditions remained mixed, with demand in key end markets such as oil and gas, mining, marine and utilities varying by region, product and customer. In this environment, ABB’s geographic, technology and channel scope mitigated some of the market turbulence and allowed the company to tap opportunities for profitable growth.

For example, industrial customers continued to invest in high-efficiency production technologies to generate more from their existing assets, such as the $260-million, 9-year order to supply integrated services for offshore oil and gas facilities in Norway. Targeted capital expenditures in important end markets also continued and included an order for mine hoists from a major customer in Russia.

Utilities made further selective power transmission investments to expand and upgrade their grids. ABB won a $110-million order to link the Lithuanian and Poland power grids, and a $150-million order to supply ultra-high voltage direct current equipment to the world’s highest capacity power transmission link in China.

Overall, ABB’s orders received in the quarter declined 4 percent on an organic basis (2 percent higher including T&B) compared to the first quarter of 2012. Base orders (below $15 million) were 5 percent lower on an organic basis (2 percent higher including T&B), mainly reflecting softer demand for early-cycle products. Service orders declined by 3 percent in the quarter—partly due to the continued exit from those full service contracts having lower pull-through of high-value ABB products—and represented 19 percent of total orders. Emerging market orders increased 10 percent and represented 48 percent of total orders. Large orders (above $15 million) were up slightly in the quarter and represented 14 percent of total orders, unchanged from the year-earlier period.

Revenues increased in the first quarter on both an organic (up 3 percent) and inorganic basis (up 10 percent), as execution of the strong order backlog helped offset early-cycle order and revenue weakness. T&B contributed approximately $590 million to orders and revenues. Service revenues increased by 3 percent in the quarter.

Q1 2013 orders received and revenues by region

Orders in Europe were flat as strong increases in eastern Europe—especially Russia—offset order declines in both northern and southern Europe, including Germany and Italy. On an organic basis, orders in the Americas declined, mainly the result of lower large orders in power and oil and gas. Asia orders increased on the back of 20-percent order growth in China, while the Middle East and Africa was steady, with strong demand for renewable energy solutions in South Africa offsetting a decline in large orders in the Middle East.

Q1 2013 orders received and revenues by division

Discrete Automation and Motion: Higher large orders in robotics and for power conversion equipment in the rail industry could not offset order declines in motors and drives resulting from generally weaker early-cycle demand. Revenues increased on the execution of the strong order backlog, especially in robotics. Service revenues increased 5 percent.

Low Voltage Products: Orders and revenues were flat on an organic basis as early-cycle demand remained near the low levels seen a year-earlier in most regions. Service orders and revenues grew at a double-digit pace.

Process Automation: Order growth in mining and marine was offset by declines in metals and pulp and paper. Oil and gas orders were flat, with growth in base orders offset by lower large orders. Service orders decreased, mainly due to several upgrade projects booked last year which were not repeated. Higher marine revenues compensated lower revenues in other businesses. Total service revenues increased 4 percent.

Power Products: The change in orders received reflects continued project selectivity in a challenging market and a comparison with a strong first quarter of 2012. Revenues were unchanged from a year earlier and included a higher share of distribution and industry-related sales.

Power Systems: The order decline partly reflects the timing of large project awards as well as increased selectivity in project tendering in order to reduce risks and secure more value-added ABB product pull-through. Revenues were higher across all businesses in the quarter and service revenues also grew.

Earnings overview

Earnings before interest and taxes (EBIT) amounted to approximately $1.1 billion, steady compared to the same quarter in 2012. Included in EBIT are the net impacts of foreign exchange and commodity timing differences(4), which reduced EBIT in the first quarter of 2013 by $62 million and increased EBIT

in the same period a year earlier by $71 million. Also included in EBIT is acquisition-related amortization of $93 million, compared to $66 million a year earlier.

Operational EBITDA in the first quarter of 2013 amounted to $1.5 billion, an increase of 19 percent compared to the relatively weak first quarter a year earlier. T&B contributed approximately $100 million to operational EBITDA.

The Group’s operational EBITDA margin increased by 1.1 percentage points compared to the same period in 2012, as sourcing initiatives and operational improvements produced cost savings of approximately $260 million compensated lower-margin orders being executed out of the power backlog. Margins were supported by improved capacity utilization and stricter discipline in selling, general and administrative (SG&A) expenses that better reflect current market conditions.

Q1 2013 earnings and cash flows by division

Discrete Automation and Motion: Stable earnings with lower margins primarily reflect a change in product mix versus the year-earlier period, driven in part by increased system revenues where margins are below the divisional average. The change in margins also reflects higher investments in selling and R&D compared to the same quarter in 2012. Higher cash from operations primarily reflects improved inventory management.

Low Voltage Products: The increase in operational EBITDA resulted primarily from the contribution of approximately $100 million from T&B. The operational EBITDA margin increased as a result of cost reductions and improved capacity utilization in several markets.

Process Automation: Higher operational EBITDA and margins primarily reflect improved project execution and lower SG&A expenses as a percentage of revenues compared to the same quarter in 2012. Profitability was also supported by strong margins in the service business.

Power Products: The increase in the operational EBITDA margin was mainly driven by a favorable business mix while cost savings mostly offset the price pressure from the execution of the order backlog.

Power Systems: Higher operational EBITDA margins mainly reflect improved project execution along with a more favorable mix of projects being executed from the order backlog compared to the same quarter a year earlier. Measures announced in the fourth quarter of 2012 to improve profitability and consistency of results continued in the first quarter but had no significant impact on earnings.

Net income

Net income for the quarter decreased 3 percent to $664 million, which included net foreign currency and derivative impacts, as well as amortization related to acquisitions as described earlier. Finance net(6) increased to $79 million from $38 million in the same quarter in 2012, reflecting the increase in total debt compared to one year ago. Basic earnings per share in the first quarter amounted to $0.29 versus $0.30 a year earlier.

Balance sheet and cash flow

Total debt amounted to $9.1 billion compared to $6.2 billion in the first quarter of 2012 and $10.1 billion at the end of 2012. The year-over-year increase primarily resulted from the issuance of approximately $3 billion of bonds in the US and Australia to secure long-term funding at attractive rates.

Net debt(6) was $2.1 billion at the end of March 2013 versus net cash(6) of $1.4 billion at the same time a year earlier. The net debt-to-EBITDA ratio(6) at the end of March 2013 was 0.4x, well within the range the company believes is required to maintain its single-A credit rating.

ABB reported cash outflows from operations of $223 million, weaker than in the first quarter in 2012, reflecting a combination of higher net working capital needed to execute large projects and the timing of customer advances, both factors related mainly to the power businesses. Net working capital as a share of revenues(6) amounted to 16.4 percent, an increase of 0.8 percentage points versus the end of the quarter a year earlier.

Technology and innovation

ABB announced a number of new products during the quarter, particularly in the area of power electronics. For example, the company launched a new 1,000 kilowatt high-efficiency solar inverter to reduce overall system costs for photovoltaic power generation, and the most compact truly modular uninterrupted power supply (UPS) on the market. A new onboard direct current (DC) power grid for marine applications allows ship operators to optimize generator speeds for lower fuel consumption as well as reducing space requirements and increasing system flexibility. In April, ABB announced the development of an innovative high voltage circuit breaker solution for power transmission with an integrated fiber optic current sensor which simplifies substation design, significantly reduces footprint requirements and is smart grid-enabled. ABB also launched the first low-voltage circuit breaker with integrated energy management functions, which has the potential to achieve annual energy savings equivalent to the electricity consumption of 1.4 million EU households per year.

Acquisitions

ABB and US-based Power-One announced earlier this week that their boards of directors have agreed to a transaction in which ABB will acquire Power-One for approximately $1 billion. The transaction would position ABB as a leading global supplier of solar inverters — the “intelligence” behind a solar photovoltaic system — to a market expected to grow by more than 10 percent per year over the

medium term. The transaction expected to close in the second half of 2013, subject to shareholder and regulatory approvals.

Outlook

Our long-term growth drivers—such as the need for greater industrial productivity, more reliable and efficient power delivery and growth in renewables—remain in place. Shorter-term trends such as industrial production growth and government policy are expected to remain the key drivers of demand over the rest of 2013. There are no clear changes in demand trends visible as we head into the second quarter of 2013.

In a market environment in which near-term uncertainty is likely to remain, we will continue to focus on executing our large order backlog and taking advantage of our broad product and geographic scope to capture profitable growth opportunities in line with our 2011-15 targets.

This will be supported by our ongoing initiatives to improve margins and project selection and execution. Growing service revenues, securing the synergies from recent acquisitions, increasing customer satisfaction and successfully commercializing our pipeline of innovative technologies will remain important contributors to our growth and profitability targets.

We will continue to drive cost savings and productivity improvements equivalent to 3-5 percent of cost of sales every year through improved supply management, better quality and higher returns on investments in sales and R&D. We remain committed to delivering higher cash to shareholders and improving returns on our capital investments in both organic and inorganic growth.
