Ericsson SECOND QUARTER report ADJUSTED for registration statement on Form F-3 (No. 333.180880) July 18, 2012

Q112 includes a gain from the divestment of Sony Ericsson of SEK 7.7 b.

COMMENTS FROM HANS VESTBERG, PRESIDENT AND CEO

“In the quarter, demand for Global Services and Support Solutions was strong, while Networks sales decreased YoY mainly due to the expected decline in CDMA equipment sales as well as lower business activity in China, including weaker sales of GSM and lower 3G sales in Russia,” says Hans Vestberg, President and CEO of Ericsson (NASDAQ:ERIC). “In Global Services all areas showed good growth in the quarter due to operators’ focus on operational efficiency and high project activities. The strong development for Support Solutions was driven by billing systems and TV solutions. Global Services and Support Solutions together represented about half of the Group’s revenues. The growing Global Services business has a dilutive impact on gross margin.

NET INCOME, SEK b.

CASH FLOW FROM OPERATIONS, SEK b.

We continue to stay close to our customers to monitor the impacts of macroeconomic development and political uncertainty in certain regions on their investments. In customer conversations it is clear that the fundamental drivers for increased data traffic are unchanged. Today there are more than 700 million smartphone subscriptions and according to our estimates this number will increase to three billion in 2017. Based on these drivers, we see an increasing focus from our customers on network performance and quality of service. This will require continuous operator investments in hardware, software and services.

Our joint venture ST-Ericsson is still in a challenging situation due to a significant drop in sales of new products to one of the largest customers and continued decline in legacy products. The company continues to focus on securing the successful execution and delivery of its NovaThor ModAp platforms and Thor modems to customers while executing on company transformation aiming at lowering its break-even point.

In 2010 we made a conscious decision to gain market share and increase technology and services leadership, well aware of the short-term profitability pressure. Our focus is now on translating these gains into sustainable profitable growth,” concludes Vestberg.

Financial Highlights

INCOME STATEMENT AND CASH FLOW

Sales in the quarter increased 1% YoY and 9% QoQ. The acquired Telcordia operation added sales of SEK 1.1 b. in the quarter, split 50/50 between segments Global Services and Support Solutions.

Networks sales decreased -17% YoY primarily due to the expected decline in CDMA equipment sales as well as weaker development for GSM sales in China and slower operator investments in Russia. Networks sales increased 2% QoQ. CDMA equipment sales declined close to -50% YoY to SEK 2 b. and are expected to continue its rapid decline in H212.

Global Services continued to show strong momentum with growth of 26% YoY and 17% QoQ and all areas grew. Global Services represented 44% (35%) of total sales in the quarter compared to 40% in Q112. Support Solutions sales were strong with 47% growth YoY and 15% QoQ driven by strong demand for billing systems and TV solutions. Both Global Services and Support Solutions were positively impacted by the added sales from the acquired Telcordia.

Ericsson restructuring charges amounted to SEK 0.6 (1.7) b., mainly related to execution of the service delivery strategy through transformation from local to global resource centers. As previously communicated, restructuring charges are estimated to approximately SEK 4 b. for the FY12.

Gross margin was down YoY to 32.0% (37.8%), and from 33.3% QoQ. The YoY decrease is due to the increased Global Services share as well as a higher proportion of coverage projects and network modernization projects in Europe. Approximately half of the YoY gross margin percentage decline is related to the increased services mix. The QoQ gross margin reduction is due to a higher Global Services share and lower sales of mobile broadband capacity than in Q112.

The underlying business mix, with higher share of coverage projects, was unchanged in the quarter and is expected to prevail short-term. The negative gross margin impact from the network modernization projects in Europe will start to gradually decline end 2012.

The modernization of networks in Europe became an opportunity for us mid-2010 when operators in Europe started to evaluate potential swaps of older 2G and 3G equipment to new multi-standard radio equipment. Ericsson, who had lost out on market share in the 3G race compared to its strong 2G position, identified this as an opportunity to regain footprint. Competition for new footprint is always tough and a strategic decision was taken to accept short-term pressure on margins to increase market share. As a result, market share has increased and the Company has restored its leading market position in Europe. Average project duration for these modernization projects are 18-24 months and the margin effects will start to gradually decline late 2012. In Q411, all projects were up to full speed.

Total operating expenses amounted to SEK 15.0 (15.8) b. R&D expenses amounted to SEK 8.1 (8.1) b. and increased slightly QoQ due to restructuring. Full year R&D expenses is now expected to be SEK 30-32 b. compared to previous estimate of SEK 29-31 b. The increase is due to selective investments in key radio technology areas to extend technology leadership and FX. Selling and general administrative expenses (SG&A) amounted to SEK 6.9 (7.7) b. SG&A is down -8% YTD, excluding restructuring charges and the impact from the acquisition of Telcordia. In Q211, SG&A was impacted by restructuring charges of SEK 1.2 b. vs. restructuring charges of SEK 0.1 b. in Q212.

Other operating income and expenses was SEK 0.5 (0.2) b. and decreased SEK -7.2 b. QoQ due to the gain of SEK 7.7 b. from the divestment of Sony Ericsson that was reported in Q112. The SEK 0.3 b. in segment Sony Ericsson relates to a resolved dispute from a litigation process with a third party.

Operating income, excluding JVs, decreased to SEK 3.3 (5.0) b. due to lower profitability in Networks but with a positive impact from lower restructuring costs. Operating margin was 5.9% (9.2%) compared to 5.5% (excl. gain from divestment of Sony Ericsson) in Q112.

Ericsson’s share in ST-Ericsson’s income before tax was SEK -1.3 (-0.7) b.

Financial net amounted to SEK -0.3 (0.3) b. and decreased QoQ from SEK 0.0 b. mainly related to negative currency exchange revaluation effects.

Net income decreased to SEK 1.2 (3.2) b. due to lower profitability in Networks and increased loss in ST-Ericsson.

EPS diluted was SEK 0.34 (0.96). Cash flow from operations was negative SEK -1.4 (5.8) b., mainly due to late invoicing in the quarter. Cash outlays for restructuring amounted to SEK 0.3 (1.2) b. Cash outlays of SEK 1.0 b. remain to be made from the restructuring provision.

DAYS SALES OUTSTANDING

INVENTORY DAYS

PAYABLE DAYS

BALANCE SHEET AND OTHER PERFORMANCE INDICATORS

Trade receivables increased QoQ to SEK 67.3 (60.7) b., reflecting changes in FX and late invoicing in the quarter. As a result, days sales outstanding (DSO) increased from 104 to 111 days QoQ due to the increase in trade receivables and change in FX.

Inventory increased QoQ to SEK 33.1 (32.5) b. Inventory turnover days decreased from 88 to 84 days.

During the quarter, Ericsson has performed refinancing activities to extend the average debt maturity profile and to further diversify funding sources:

Cash, cash equivalents and short-term investments amounted to SEK 66.4 (75.6) b. Capex investments amounted to SEK 1.6 (1.0) b.

During the quarter, approximately SEK 0.9 b. of provisions was utilized, of which SEK 0.3 b. related to restructuring. Additions of SEK 0.6 b. were made, of which SEK 0.2 b. related to restructuring. Reversals of SEK 0.5 b. were made.

Total number of employees at the end of the quarter decreased to 108,095 (108,551). The reduction is mainly related to efficiency programs in service delivery and within sales and administration.

SEGMENT SALES, SEK b.

NETWORKS QUARTERLY SALES, SEK b.

Segment Results

NETWORKS

CDMA equipment sales decreased -50% YoY to SEK 2 b. in the quarter. CDMA equipment sales are expected to continue its rapid decline in H212. YoY sales were negatively impacted by lower business activity in China, including weaker sales of GSM as well as lower 3G sales in Russia and reduced operator investments in India.

In 2010, we acquired Nortel’s CDMA business in order to strengthen our position in North America. We were quickly established as the market leader in North America. Already at the acquisition, CDMA equipment sales were expected to decline due to the subsequent rapid shift to LTE. The CDMA acquisition has created substantial value for the company.

Ericsson has made good inroads in the converged IP Edge market with seven contracts for the Smart Services Router (SSR) signed to date.

Operating margin was negatively impacted YoY by lower volumes as well as the underlying business mix, with more coverage than capacity projects, and the European network modernization projects. The QoQ decline is also impacted by lower sales of mobile broadband capacity than in Q112.

After the initial large scale LTE rollouts in the US, Japan and Korea, we now start to see other countries following and we expect LTE deployments to commence on a broader scale also in e.g. Europe and Latin America. We have a well proven LTE solution, outperforming competition, and according to measurements end of 2011, we have a 60% market share measured in LTE volumes.

Focus is on improving profitability and leveraging the installed base. Other key priorities are to grow IP sales and secure contracts for Voice over LTE. In CDMA, the priority is to support customers’ migration to our LTE solution and excel in life cycle management.

GLOBAL SERVICES QUARTERLY SALES, SEK b.

GLOBAL SERVICES

All areas showed strong growth in the quarter and business momentum remains. The increase in Professional Services is to a large extent driven by Managed Services and Consulting & Systems Integration. The demand for Professional Services is driven by operators’ focus on increasing operational efficiency and reducing opex through transformation activities in the voice, IP and OSS/BSS domains as well as outsourcing. Also this quarter, Network Rollout sales increased YoY, driven by high volumes of network modernization in Europe and coverage projects in other regions.

Global Services operating margin increased YoY due to increased profitability in Professional Services, positively impacted by an improvement in all areas as a result of increased sales and lower restructuring charges. Network Rollout operating margin continued to be negatively impacted by the network modernization projects in Europe. The margin impact from restructuring charges was 2%-points Q212 for Global Services as well as Professional Services, compared to 3%-points in Q211.

Ericsson now supports networks with more than 2.5 billion subscribers.

SUPPORT SOLUTIONS QUARTERLY SALES, SEK b.

SUPPORT SOLUTIONS

The acquired Telcordia operation added sales of SEK 0.55 b. in the quarter. The strong YoY development in the quarter is related to billing solutions in Middle East and Sub-Saharan Africa. The solid growth in TV is especially related to IPTV and compression.

Operating margins improved YoY due to increased volumes and favorable product mix. Focus continues to be on transforming the business for sustainable profit generation as well as integrating Telcordia. Support Solutions is a software business with a high fixed cost base, which makes profitability volume driven.

Number of subscribers served by our charging and billing solutions were 1.7 billion at end of period.

ST-ERICSSON

ST-Ericsson’s sales increased 19% QoQ, reflecting a significant ramp-up of volumes of NovaThor platforms shipping to its major customers. The net debt at the end of the quarter was USD -1.2 b. Last quarter net debt was USD -1.0 b. ST-Ericsson is reported in US GAAP and Ericsson’s share in ST-Ericsson’s income before tax, adjusted to IFRS, was SEK -1.3 (-0.7) b. in the quarter. By the end of the quarter, ST-Ericsson had utilized USD 1.2 b. of a short-term credit facility of USD 1.4 b. granted on a 50/50 basis by the parent companies, which corresponds to an increase of USD 260 m. since Q112.

Ericsson Group balance sheet items related to its investment in ST-Ericsson (IFRS);

Though their path to success is challenging, ST-Ericsson continues to focus on securing the successful execution and delivery of its NovaThor ModAp platforms and Thor modems to customers while executing a company transformation aiming at lowering its break-even point.

Ericsson accounts for ST- Ericsson in accordance with the equity method which means that Ericsson share of income after tax in ST-Ericsson increases or decreases the carrying investment amount.

Regional Overview

In Segment Networks “Other” includes licensing revenues, sales of cables, power modules and other businesses. Revenue from the acquired Telcordia business operation, consolidated January 2012, is reported 50/50 between segments Global Services and Support Solutions. In the regional dimension, all of the Telcordia sales are reported in the Support Solution segment except for North America where it is split 50/50 between Global Services and Support Solutions. Multimedia brokering (IPX) was previously reported in each region in segment Support Solution. As of Q112 it is part of region “Other” in segment Support Solutions.

North America. Network sales were negatively impacted by the decline in CDMA sales, however, partly offset by the continued transition to LTE. Major wireless network expansion and transformation projects contributed to the growth in Global Services sales. The acquisition of Telcordia has generated momentum in OSS/BSS.

Latin America. The YoY increase was driven by services. Network Rollout sales increased due to project executions in Brazil, Chile and Mexico. Support Solutions increased due to Telcordia acquisition and strong sales in charging. Operators in Brazil and Mexico are preparing for LTE deployments.

Northern Europe and Central Asia. Sales of Networks decreased YoY mainly due to continued low investment levels in Russia. Solid increase in sequential sales due to continued modernization projects and the win of a WCDMA contract with pan-Russian operator Rostelecom. In the Nordics, all major operators have now launched LTE services.

Western and Central Europe. The region sees some impact from the macroeconomic environment causing cautious operator capex spending and focus on measures to improve efficiency. Most operators are looking at transformation of their OSS/BSS environments. As a result, sales of Global Services and Support Solutions represent more than 60% of the sales in the region and there is continued good momentum for managed services.

Mediterranean. Sales growth is mainly driven by network modernization projects, which drive both sales of networks and services. In Global Services, both Network Rollout and Systems Integration sales contributed to the positive development. Operators focus on mobile broadband in order to meet traffic growth, quality demands and secure network performance.

Middle East. YoY sales growth was mainly driven by sales in Global Services and Support Solutions. Political unrest is still impacting the region and operators in those countries continue to be cautious with infrastructure investments. Services grew, especially in Managed Services and Systems Integration, as operators are looking into network performance quality and operational efficiencies.

Sub-Saharan Africa. Sales increased YoY and QoQ, driven by increased investments in 2G. 2G investments are expected to level out, while 3G will increase. Mobile broadband penetration is slowly expanding from its low level of 4% today, as low cost smartphones enter the market and the internet connectivity is improving.

India. Some recovery in network capex spend as operators have started focused investments in areas where data traffic is growing. YoY sales decreased due to the strong H111, when the initial 3G deployments peaked. Regulatory uncertainties continue in India.

China and North East Asia. The YoY decrease in Networks is mainly related to lower sales of GSM and generally lower business activity in China, as well as continued transition to LTE in Korea, impacting 3G sales. Services sales were driven by more turnkey projects in Japan. The product mix is rapidly changing towards more of initial LTE deployments and a larger share of services.

South East Asia and Oceania. Networks sales increased YoY in several countries, driven by 3G investments and initial LTE deployments. The QoQ increase is due to capacity investments in Indonesia and deployments in other markets. Global Services reported an increase YoY driven by network rollout and support services aligned with infrastructure investments.

Other. Licensing revenues continued to show a stable development YoY. Also sales of cables, power modules and other businesses are included in “Other”. Multimedia brokering (IPX) was previously reported in each region, but from Q112 it is part of “Other”, under Support Solutions.
