Investor Relations Shareholder Letter News from our Sectors 02/03 Siemens 2014 04 OSRAM 05 Financial Highlights*

On May 2, 2013 Siemens published its financial results for the second quarter of fiscal year 2013. Overall, the quarter showed a mixed picture. On the one side, we saw some positive developments, such as a higher number of large orders resulting in a Ladies and Gentlemen, Dear Shareholders, substantial order growth of 20%. We saw an improved cash conversion and receivables management that resulted in a strong cash flow. On the flipside, our revenue declined versus the previous year’s quarter, partially because the comparable quarter in 2012 was particularly strong, and partially due to some weakness in the short cycle business as impacted by the global environment. Our profitability level was burdened by some project charges, mainly in the Transmission business and due to delivery delay of high speed trains. On the macroeconomic level, the environment remained challenging with a continued recession in the Eurozone and little tailwind in markets like the US and China. To summarize, as President and CEO, Peter Löscher, puts it: “Results for the second quarter show a mixed picture. While we were able to clearly increase orders, we still have challenges regarding revenue and profit. Even more, we’re focusing on the factors that lie in our own hands: we’re rigorously executing our company-wide ‘Siemens 2014’ program.” In the next few pages, we will elaborate to you further on some of the large orders that we’ve been awarded this quarter, and present to you the quarterly results of each sector. As our feature topic in this issue, we will provide you with details on the ‘Siemens 2014’ productivity program. Finally we will answer some of the key questions regarding the planned OSRAM spin-off. I would like to thank you, our shareholders, for your continuous commitment and interest in Siemens.

Shareholder Letter 3 Industry Infrastructure & Cities News from our sectors How does Siemens assess the further course of fiscal year 2013? Q2 2013 results: §Challenging market conditions cause weakness in short-cycle businesses and renewable energy offerings Siemens at the Hanover Fair – Preparing the way for Industry 4.0 At this year’s Hanover Fair, Siemens showcased how the company and its customers will meet today’s challenges and shape the new production age. Siegfried Russwurm, CEO of the Industry sector pointed out “Never before has the world of manufacturing and production technology been changing as rapidly and fundamentally as today”. There is some way to go until Industry 4.0 becomes reality, but Siemens today is laying the essential foundations for its implementation. A decisive role is played here by innovative industrial software which allows the integration of product development and production, and consequently paves the way for the holistic optimization of product development and production processes. “The increasing penetration of IT and the growing integration of all industrial technologies are taking place in evolutionary steps from today’s perspective.“(for further information, please click here) Anti-trust authorities give their consent to Siemens’ acquisition of Invensys The European Commission has given its consent to Siemens’ acquisition of Invensys Rail, a leading global supplier of signaling and control equipment for rail, with a strong footprint and a well established reputation in its domestic markets UK, Spain, the U.S. and Australia. Meanwhile, Siemens successfully closed the acquisition on May 2, 2013. Roland Bush, CEO of Siemens’ Infrastructure & Cities sector, stated: “We are combining two of the strongest organizations for the rail automation market of the future. This business will ensure profitable growth opportunities worldwide for the Siemens Infrastructure & Cities Sector and create a truly global player. It also underscores the Sector strategy of expanding automation know-how.” (for further information, please click here) Q2 2013 results: §Strong growth in order intake, mainly driven by major orders in Europe §Project charges due to delayed delivery of high speed trains In fiscal 2013, Siemens is implementing ‘Siemens 2014’, a company-wide program supporting our One Siemens framework for sustainable value creation. The goal of the program is to raise our Total Sectors profit margin to at least 12% by fiscal 2014. For fiscal 2013, we confirm our expectations of moderate organic order growth. With continuing challenges for our businesses whose results react strongly to short-term changes in the economic environment, we now anticipate a moderate decline in revenue on an organic basis compared to the prior year. Charges associated with the ‘Siemens 2014’ program in the Sectors are expected to total up to 0.9 billion Euro for the full fiscal year. Given these developments and financial results for the first half, we expect income from continuing operations in fiscal 2013 to approach the low end of our original expectation, 4.5 billion Euro, before impacts related to legal and regulatory matters and significant portfolio effects which we expect to burden income by up to 0.5 billion Euro due primarily to the solar business.
