Adds Innovative Hospitality and Retail Technology Vendor to

Expand Oracle into More Industries

REDWOOD SHORES, Calif. – June 23, 2014

Oracle today announced that it has entered into a definitive agreement to acquire MICROS Systems, Inc. (NASDAQ: MCRS), a provider of integrated software and hardware solutions to the Hospitality and Retail industries, for $68.00 per share in cash. The transaction is valued at approximately $5.3 billion, or $4.6 billion net of MICROS’ cash.

Cloud, mobile, social, big data and the internet of things are impacting every industry, encouraging companies to modernize in order to compete effectively. The addition of MICROS extends Oracle’s offerings in industries by combining MICROS’ industry specific applications with Oracle’s business applications, technologies and cloud portfolio. Together, Oracle and MICROS will help hotels, food & beverage facilities, and retailers to accelerate innovation, transform their businesses, and delight customers with complete, open and integrated solutions.

The Board of Directors of MICROS has unanimously approved the transaction. The transaction is expected to close in the second half of 2014, subject to MICROS stockholders tendering a majority of MICROS’ outstanding shares and shares representing vested equity incentive awards in the tender offer, certain regulatory approvals and other customary closing conditions.

“Oracle has successfully helped customers across multiple industries, harness the power of cloud, mobile, social, big data and the internet of things to transform their businesses,” said Oracle President Mark Hurd. “We anticipate delivering compelling advantages to companies within the Hospitality and Retail industries with the acquisition of MICROS.”

“MICROS has been focused on helping the world’s leading brands in our target markets since we were founded in 1977, including running more than 330,000 sites across 180 countries today,” said Peter Altabef, President and CEO, MICROS. “In combination with Oracle, we expect to help accelerate our customers’ ability to innovate and differentiate their businesses by utilizing Oracle’s technologies, cloud solutions and scale. We are very excited about the great opportunities this will create for our customers and employees.”

“We are committed to protecting and enhancing customer investments in MICROS solutions. MICROS’ management and employees will form a dedicated business within Oracle to maintain their focus on serving customers,” said Executive Vice President for Oracle Global Business Units Bob Weiler. “Our industry organizations maintain deep domain expertise and focused investment, which includes more than 18,000 Oracle employees and over $500 million in annual R&D spend. This model has proven highly successful across several industries, and we look forward to bringing these same benefits to the customers of MICROS.”

“We expect this transaction to be immediately accretive to Oracle’s earnings on a non-GAAP basis and to expand over time,” said Oracle President and CFO Safra Catz.

Oracle Buys MICROS Systems

Adds Innovative Hospitality and Retail Technology

Vendor to Expand Oracle into More Industries

On June 23, 2014, Oracle announced that it has entered into an agreement to acquire MICROS Systems, a provider of integrated software and hardware solutions to the Hospitality and Retail industries. The proposed transaction is expected to close in the second half of 2014. Until the transaction closes, Oracle and MICROS will continue to operate independently and it is business as usual.

MICROS offers a range of software, hardware and related services along with rapidly growing cloud solutions to manage hotels, food & beverage facilities, and retailers. MICROS’ proven and innovative technologies are built and serviced by more than 6,600 employees with deep domain expertise and are in use across 330,000 customer sites in 180 countries.

Oracle offers complete and best-in-class products throughout an integrated stack of hardware and software, with every layer designed and engineered to work together in the cloud and data center. By eliminating complexity and simplifying IT, Oracle’s cloud-based and on-premises solutions enable more than 400,000 customers in more than 145 countries to accelerate innovation and create added value for their customers.

Cloud, mobile, social, big data and the internet of things are impacting every industry, encouraging companies to modernize in order to compete effectively. The addition of MICROS extends Oracle’s offerings in industries by combining MICROS’ industry specific applications with Oracle’s business applications, technologies and

cloud portfolio. Together, Oracle and MICROS will help Hospitality and Retail companies to accelerate innovation, transform their businesses, and delight customers with complete, open and integrated solutions.

Oracle is committed to protecting and enhancing customer investments in MICROS solutions. MICROS’ management and employees will form a dedicated business within Oracle to maintain their focus on serving customers. Oracle’s industry organizations

maintain unique domain knowledge, specialized expertise and focused product investments, which currently includes more than 18,000 Oracle employees and over $500 million in annual R&D spend. This model has proven highly successful across several industries, and we look forward to bringing these same benefits to the customers of MICROS.

PRODUCT OVERVIEW AND STRATEGY

What is the rationale for this acquisition?

More than ever, businesses across many industries are modernizing their organizations to compete more effectively. The combination of Oracle and MICROS is expected to accelerate customers’ ability to innovate and differentiate their businesses by leveraging Oracle’s technologies, cloud solutions, and global reach and scale.

What products and services does MICROS offer?

The world’s leading Hotel, Food & Beverage, and Retail brands choose MICROS’ expansive suite of solutions to better address their customers’ rapidly changing service expectations. MICROS customers are known to deliver some of the most exceptional customer service interactions, relying heavily on advanced technology to modernize their organizations. MICROS provides industry specific solutions through integrated software, hardware, and related services.

CUSTOMERS AND PARTNERS

How is the proposed transaction between Oracle and MICROS expected to benefit customers?

Customers will also benefit from accelerated R&D investment in products and services that address the most critical customer-facing and revenue-producing aspects of organizations. Oracle plans to extend and expand MICROS’ ability to sell, service and support customers around the world by utilizing Oracle’s global scale and resources.

How does Oracle plan to maintain MICROS’ domain expertise after the closing?

MICROS brings tremendous domain expertise. MICROS’ management team and employees will become part of a dedicated business within the Oracle Industry organization. The team will enhance Oracle’s Global Business Units (GBU) organization with the addition of MICROS.

How will the proposed acquisition impact the MICROS product roadmap?

Oracle is committed to protecting and enhancing customer investments in MICROS solutions. After the close of the transaction, Oracle plans to continue to invest in the Hospitality and Retail industries. We expect this will add additional functionality and capabilities at a quicker pace. In addition, MICROS customers will benefit from better integration and alignment with Oracle’s other product offerings.

Yes, MICROS products and services will continue to be available. Please contact a MICROS sales representative to assist you, or visit www.micros.com for contact information.

Should MICROS customers continue to call MICROS customer support?

How will Oracle continue to support and broaden relationships with MICROS partners?

We expect business to continue as usual for MICROS partners. If contact information changes, we will communicate these changes through normal channels. Oracle partners may also use their existing Oracle channels for support to answer any questions.
