“Sales showed positive development in the quarter with a growth of 2%YoY, despite currency headwind,” said Hans Vestberg, President and CEO of Ericsson. (NASDAQ:ERIC).

“The sales increase was primarily driven by Networks and rollout services, following high project activities primarily in Europe and North America. North America remained the strongest region and showed a growth of 23% despite the decline in CDMA. North East Asia had a challenging quarter with lower sales in South Korea, which remains one of the most advanced LTE markets but without parallel 3G deployments as in Q112,continued structural decline in GSM investments in China and FX effects in Japan.

Looking at the areas of portfolio momentum, we see continued good development in Managed Services with 21 new contracts signed during the quarter. Within the Mobile Broadband area, the vendor selection processes for 4G/LTE in Russia and China have been initiated. We also see continued momentum for our SSR routing platform with 12 new contracts in the quarter. Within OSS and BSS demand continued to be strong.

At the Mobile World Congress (MWC) in Barcelona the trends in focus verify our belief that the Networked Society is coming to life. The growth in data traffic and video in the networks drives demand for mobile broadband and OSS and BSS. Other key topics at the MWC were software defined networks, cloud and machine-to-machine communications that will all be part of shaping the industry for the coming years.

Profitability improved YoY, adjusted for the restructuring charges related to the reduction of operations in Sweden concluded in Q1 and last year’s gain from the divestment of Sony Ericsson. The improvement is mainly due to higher sales in Networks and a continued reduction in operating expenses, offset by negative operating income in Network Rollout and negative FX effects.

The underlying business mix, with a higher share of coverage projects than capacity projects, continued as anticipated during the quarter. With present visibility of customer demand, and current global economic development, we continue to believe that the underlying business mix will start to gradually shift towards more capacity projects during the second half of 2013.

We continue to execute on our strategy. During the quarter we announced the way forward for our JV ST-Ericsson and in April 2013 we announced our intention to acquire Microsoft’s Mediaroom to strengthen our media position.

While macroeconomic and political uncertainty continues in certain regions, the long-term fundamentals in the industry remain attractive and we are well positioned to continue to support our customers in a transforming ICT market,” concludes Vestberg.

During the quarter, the SEK was further strengthened, negatively impacting sales especially in JPY and USD.

Networks sales increased 3% YoY, primarily driven by North America and South East Asia. Networks sales decreased -20% QoQ, partly due to lower sales in North East Asia, offset by continued high business activity in North America.

Global Services grew 4% YoY, driven by Network Rollout and decreased -24% QoQ, partly due to lower business activity in North East Asia and delays in LTE deployments in Latin America.

Support Solutions sales declined -19% YoY and -33% QoQ, mainly due to the divestment of Multimedia Brokering (IPX) in Q312 and negative FX effects.

Restructuring charges for the Group amounted to SEK 1.8 (0.6) b. of which SEK 1.4 b. related to the significant reduction of operations in Sweden. We also continued to execute on our service delivery strategy to move service delivery local resources to global centers, although at a slower pace this quarter.

Gross margin decreased YoY to 32.0% (33.3%), and increased from 31.1% Q412. The YoY decrease was due to lower Network Rollout margin and higher restructuring charges. This was partly offset by gradually declining effects from the network modernization projects in Europe, which also explain the sequential margin improvement.

With present visibility of customer demand, and current global economic development, we continue to believe that the underlying business mix will start to gradually shift towards more capacity projects during the second half of 2013. The negative impact from the network modernization projects in Europe will continue to gradually decline during 2013.

Total operating expenses increased YoY by SEK 0.3 b. to SEK 14.5 (14.2) b. due to increased restructuring charges in the quarter. R&D expenses amounted to SEK 7.9 (8.0) b. and included restructuring charges of SEK 0.6 (0.0) b. Selling and general administrative expenses (SG&A) increased YoY to SEK 6.6 (6.2) b. due to restructuring charges of
SEK 0.6 (0.1) b.

Other operating income and expenses amounted to SEK 0.0 (7.7) b. Last year’s divestment of Sony Ericsson resulted in a gain of SEK 7.7 b. In the quarter we changed the hedge accounting for new hedges made 2013 and onwards (see Accounting Policies). The hedge effect on other operating income was SEK -0.1 b.

Ericsson’s share in ST-Ericsson’s income before tax was SEK 0.0 (-1.4) b.

Operating income, including JV, decreased to SEK 2.1 (9.1) b. mainly due to restructuring charges relating to the reduction of operations in Sweden and high 2012 comparison due to the gain related to the

divestment of Sony Ericsson. Operating income was also negatively impacted by FX effects both YoY and QoQ. Operating margin including JV was 4.0% (17.8%).

Financial net amounted to SEK -0.4 (0.0) b. and decreased QoQ from SEK -0.1 b. mainly due to lower interest income and currency revaluation effects including impact from devaluation in Venezuela. Tax costs were SEK -0.5 (-0.3) b.

Net income decreased to SEK 1.2 (8.8) b. following the decline in operating income.

EPS diluted was SEK 0.37 (2.76).

Trade receivables increased QoQ to SEK 65.1 (63.7) b.and inventory increased QoQ to SEK 29.8 (28.8) b., due to high business and project activities. Accounts payable decreased as a consequence of the high volumes in Q412.

Cash, cash equivalents and short-term investments amounted to SEK 72.1 (76.7) b. The net cash position decreased QoQ by SEK -6.3 b. to SEK 32.2 (38.5) b., primarily due to the negative operating cash flow and reclassification of Swedish special payroll taxes of SEK 1.8 b. from Other current liabilities to Pension liabilities in line with the implementation of IAS19R on January 1, 2013.

During the quarter, approximately SEK 0.8 b. of provisions were utilized, of which SEK 0.3 b. were related to restructuring. Additions of SEK 1.9 b. were made, of which SEK 1.6 b. related to restructuring. Reversals of SEK 0.2 b. were made.

The negative cash flow from operating activities was driven by increased working capital of SEK 4.6 b. Cash outlays for restructuring amounted to SEK 0.3 (0.4) b. Cash outlays of SEK 2.4 b. remain to be made from the restructuring provision.

The total number of employees decreased QoQ to 109,648 (110,255) due to continued efficiency improvements. The reduction of operations in Sweden had limited impact on headcount in Q1.

The structural decline in CDMA continued with -42% in the quarter to SEK 1.3 b. Sales declined QoQ due to the continued structural decline of GSM sales in China as well as declining sales in Japan, mainly due to FX effects. The business activity in North America remained high in the quarter.

The operator focus on monetizing their increasing data traffic is driving demand for mobile broadband including our 4^th Generation IP solutions. There is good momentum for the SSR routing platform with 51 contracts signed since launch in December 2011, of which 12 new contracts were signed in Q1 2013.

The worldwide LTE radio access deployments continue to drive demand also for HSPA, packet core networks and VoLTE. In early February, Ericsson signed its 100^th Evolved Packet Core (EPC) contract. We see a trend of higher adoption rate for software features as operators aim for differentiated services, higher network performance and increase their focus on cost effectiveness.

Operating margin was flat YoY, negatively impacted by restructuring charges related to reductions of operations in Sweden. Total restructuring charges in the quarter were SEK 1.3 (0.1) b. The operating margin decline QoQ was due to lower sales volumes. This was partly offset by reduced underlying operating expenses and the gradually decreasing negative effect from the network modernization projects in Europe.

Sales declined QoQ partly due to lower business activity in North East Asia and delays in LTE deployments in Latin America.

Professional Services sales were slightly down, impacted by currency headwind as well as lower Network Design & Optimization and Consulting &System Integration activities in the quarter.

The good momentum in Professional Services continues with 21 new Managed Services contracts signed in the quarter and eight new significant Consulting and Systems Integration contracts signed.

The IS/IT related Managed Services and Consulting and Systems Integration business is picking up speed driven by the ongoing business transformation in the industry.

Operating margin for Global Services decreased YoY as a result of increased losses in Network Rollout, partly due to continued high activity in the network modernization projects in Europe and delayed LTE rollouts in Latin America leading to additional project costs. Professional Services shows stable margin development.

Restructuring charges of SEK 0.4 (0.5) b. in the quarter had a negative impact on operating income.

Multimedia brokering (IPX) was divested in Q312,which impacted sales negatively YoY. IPX sales amounted to SEK 0.4 b in Q112. Demand for OSS and BSS continued to be strong, driven by operators’ focus on improving efficiency and adapting to mobile broadband business requirements. Media management sales declined YoY following a strong Q112 and a technology shift of our video compression portfolio.

We continue to implement our Support Solutions strategy communicated during Q112 with a more focused and concentrated portfolio. During the past year we have executed significant portfolio changes. On April 8, 2013, we announced our intention to

acquire Microsoft’s TV solution business Mediaroom, further strengthening our position in the growing media management market.

Operating margin was negatively impacted by restructuring charges and lower sales volumes. Efficiency improvements and portfolio streamlining contributed positively. Restructuring charges in the quarter were SEK0.1 (0.0) b. which means that the underlying operating margin was positive.

The number of subscriptions served by Ericsson’s charging and billing solutions was 2.0 billion at end of period.

As announced on March 18, 2013, ST-Ericsson will be split between the parents. Ericsson will take on the design, development and sales of the LTE multimode thin modem business products, including 2G, 3G and 4G multimode. ST Microelectronics will take on the existing ST-Ericsson products, other than the LTE multimode thin modems and related business, as well as certain assembly and test facilities. The remaining parts of ST-Ericsson will be closed down. Both parents are assuming equal funding of the wind-down related activities. The formal transfer of the relevant parts of ST-Ericsson to the parent companies is expected to be completed during the third quarter of 2013, subject to regulatory approvals.

ST-Ericsson’s sales in the first quarter of 2013 decreased 28% sequentially to USD 256 million reflecting, as anticipated, seasonal factors, no revenues from licensing and softer market conditions. ST-Ericsson’s operating loss in the first quarter of 2013 was USD -158 million.

Ericsson’s share in ST-Ericsson’s income before tax was SEK 0.0 (-1.4) b. As of December 31, 2012 there are no remaining investments related to ST-Ericsson on Ericsson’s balance sheet and therefore no result from ST-Ericsson is included in Ericsson’s result.

In Q412, Ericsson made a provision of SEK 3.3 b. which provides for Ericsson’s share of obligations for the wind-down of ST-Ericsson. Ericsson incurred cash of SEK 0.5 b. in the quarter, which resulted in a net liability of SEK 2.8 b.

We are progressing as planned toward a Q313 transaction close to separate the thin modem business from ST-Ericsson and integrate into Ericsson. Our focus is on continued execution during the transition period and to continue engagement with customer development teams.

Once the multimode thin modem business has been fully integrated into Ericsson in Q413 the operation will continue to be reported as a segment. Our current best estimate is that it will generate operating losses of approximately SEK -0.5 b. in Q413 primarily related to R&D expenses.

Income after financial items was SEK 1.2 (5.1) b. The Parent Company’s financial position had the following major changes during the quarter; decreased cash, cash equivalents and short-term investments of SEK -4.7 b. and decreased current and non-current receivables from subsidiaries of SEK 6.7 b. At the end of the quarter, cash, cash equivalents and short-term investments amounted to SEK 52.7 (57.4) b.

By the end of the quarter ST-Ericsson had utilized USD 77 million (SEK 0.5 b.) of a short-term credit facility. In Q4 2012, Ericsson made a provision of SEK 3.3 b. which provides for Ericsson’s share of obligations for the wind-down of ST-Ericsson. Ericsson incurred cash of SEK 0.5 b. in the quarter, which resulted in a net liability of SEK 2.8 b.

In accordance with the conditions of the long-term variable remuneration program (LTV) for Ericsson employees, 2,588,932 shares from treasury stock were sold or distributed to employees during the first quarter. The holding of treasury stock at March 31, 2013, was 82,209,163 Class B shares.

Samsung litigation

On November 27, 2012, Ericsson filed two patent infringement lawsuits in the US District Court for the Eastern District of Texas against Samsung. Ericsson seeks damages and an injunction. Ericsson also asked the Court to adjudge that Samsung breached its commitment to license any standard-essential patents it owns on fair, reasonable, and non-discriminatory terms and to declare Samsung’s allegedly standard essential patents to be unenforceable. On November 30, 2012, Ericsson filed a complaint with the US International Trade Commission (ITC) seeking an exclusion order blocking Samsung from importing certain products into the US. On December 21, 2012, Samsung filed a complaint with the ITC seeking an exclusion order blocking Ericsson from import of certain products into the US.

On March 18, 2013, Samsung filed its answers and counterclaims in the Ericsson suits (above) in Texas, USA.

Airvana litigation

In February 2012, Airvana Networks Solutions Inc (Airvana) filed a complaint against Ericsson in the Supreme Court of the State of New York, USA, alleging that Ericsson has violated key contract terms and misappropriated Airvana trade secrets and proprietary information. Airvana is seeking damages of USD 330 million and to enjoin Ericsson from developing, deploying or commercializing Ericsson products allegedly based on Airvana’s proprietary technology.

On March 19, 2013 the Court issued a preliminary injunction barring Ericsson or any party in privity with Ericsson from using, operating, testing or deploying certain Airvana-based EV-DO hardware unless it is executing software that is licensed from Airvana.

The Court also confirmed that it will conduct a separate, related hearing starting in April on a second preliminary injunction motion filed by Airvana seeking to prevent deployment of the Digital Baseband Advanced (“DBA”) hardware with any EV-DO software other than Airvana’s.

Reduction of number of employees in Sweden

On March 27, 2013 the company announced the reductions of operations in Sweden. In total 1,399 positions were impacted with 919 employees notified. All sites in Sweden were affected except Falun, Hudiksvall, Kalmar and Katrineholm. Restructuring charges associated with these actions were SEK 1.4 b. impacting Group results in Q1, 2013.

Acquisition of Devoteam Telecom & Media operations

On January 21, 2013, Ericsson announced its intention to acquire Devoteam Telecom & Media operations in France. The completion of the acquisition is subject to consultation and customary closing conditions and is expected to take place by the beginning of Q2, 2013.

On new positions

As of April 1, 2013, Jan Signell is appointed Head of Region North East Asia and a member of Ericsson’s Global Leadership Team, reporting to Chairman of Asia-Pacific, Mats H Olsson. Jan Signell is currently Head of Customer Unit Japan within Region North East Asia, and will remain in this role until a successor is appointed.

As of June 3, 2013, Chris Houghton is appointed Head of Region India and a member of Ericsson’s Global Leadership Team, reporting to Chairman of Asia-Pacific, Mats H Olsson. Chris Houghton is currently Head of Customer Unit UK & Ireland.

POST-CLOSING EVENTS

Ericsson to acquire Microsoft Mediaroom

On April 8, 2013, Ericsson announced that the company has reached an agreement with Microsoft to acquire its TV solution Mediaroom business. This will make Ericsson the leading provider of IPTV and multi-screen solutions with a market share of over 25%. The agreement is subject to customary regulatory approvals and other conditions.

DISCLOSURE PURSUANT TO SECTION 219 OF THE IRAN THREAT REDUCTION AND SYRIA HUMAN RIGHTS ACT OF 2012 (ITRA)

During the first quarter of 2013, Ericsson made sales of telecommunications infrastructure related products and services in Iran to MTNIrancell and to Mobile Communication Company of Iran, which generated gross revenues (reported as net sales) of approximately SEK 249 million. Ericsson does not normally allocate quarterly net profit (reported as net income) on a country-by-country or activity-by-activity basis, other than as set forth in Ericsson’s consolidated financial statements prepared in accordance with IFRS as issued by the IASB. However, Ericsson has estimated that its net profit from such sales, after internal cost allocation, during the first quarter of 2013 would be substantially lower than such gross revenues.

Ericsson’s operational and financial risk factors and uncertainties along with our strategies and tactics to mitigate risk exposures or limit unfavorable outcomes are described in our Annual Report 2012. Compared to the risks described in the Annual Report 2012, no material, new or changed risk factors or uncertainties have been identified in the quarter.

Risk factors and uncertainties in focus short-term for the Parent Company and the Ericsson Group include:

Ericsson stringently monitors the compliance with all relevant trade regulations and trade embargos applicable to dealings with customers operating in countries where there are trade restrictions or trade restrictions are discussed. Moreover, Ericsson operates globally in accordance with Group policies and directives for business ethics and conduct.
