To our Shareholders:

For 20152017 combined product and service revenue was $475.5M,$480.9M, operating income was $67.1M$64.0M and net income was $70.1M,$77.4M, up 4.0%, down 8.0%, 38.4%8.5% and 43.3%up 6.2% respectively compared to the prior year. Even though annual revenue and income declined again, MEDITECH continues to be quite profitable and financially strong. More importantly, quarterly reductions in total revenue and operating income have been reversed since 1st quarter 2015. In each subsequent quarter these operating results have surpassed those of the prior quarter. After three years of quarterly declines, we are finally growing again.

We enter 2016are very pleased with renewed hopethe year just ended and expectations.we emphasize a few accomplishments. 2017 product revenues increased by 21.2% compared to that of 2016. 2017 product bookings increased 25.6% compared to that of 2016. The downward trend of product revenue and bookings which began in the 2011/2012 timeframe has finally been reversed. Our new products, implementation methods, and talented staff should result in a growing number of sales and implementations. Last year we brought a handful of customers live with our web and mobile based ambulatory system with more to come this year. Now our ability to demonstrate, sell and implement ourminimize implementation slippages in each quarter has restored a far better sense of credibility in forecasting the next quarter. Finally, during 2017 we achieved the live status of numerous ambulatory sites, the delivery of browser based mobile physician products for acute care system will re-establish MEDITECH's reputation by providing valueand emergency departments, and the announcement of cloud based systems with cutting edge products and services which enhance the safety and productivity of the medical care delivered by our customers.Meditech as a Service (MaaS) for critical access hospitals.

We ended the year with almost 3,7503,740 staff members. We extend our gratitude to all those whose efforts produced these results:

In addition, we thank MEDITECH's Officers and managers for their efforts, dedication and loyalty as well as MEDITECH's Board members for their valued advice and active participation.

DanWe note with sadness the recent passing of Roland L. Driscoll who served as MEDITECH's Chief Financial Officer and Board member for many years. We also note with sadness the recent passing of Louis P. Valente haswho served as a Board member for 44many years and we are so grateful for his wisdom during that time. Recently he has decided to step down and in so doing recommends that a woman be selected to replace him at the upcoming 2016 Annual Meeting of Shareholders. After having a men only Board for so long, of late mostly old men, recommending Barbara Manzolillo in particular will be a welcome change.

We provide herein the Formal Notice for the upcoming Annual Meeting of Shareholders, the Proxy Statement and the 20152017 Annual Report on Form 10-K, which includes MEDITECH's Audited Financial Statements for the year just ended.

SHAREHOLDER PROPOSALS TO BE SUBMITTED AT THE ANNUAL MEETING

The Board of Directors carefully considers all proposals and suggestions from Shareholders. When adoption is in the best interest of MEDITECH and its Shareholders, and can be accomplished without Shareholder approval, the proposal will be implemented without inclusion in the proxy material or presentation to Shareholders for consideration at the Annual Meeting.

Examples of Shareholder suggestions which have been adopted over the years include improved procedures involving dividend payments and Shareholder disclosure materials, and changes or additions to the proxy material concerning such matters as abstentions from voting and confidentiality of Shareholder voting.

Shareholder proposals submitted for inclusion in MEDITECH's Proxy Statement and Proxy Page for next year's Annual Meeting must be received by MEDITECH at its corporate offices on or before November 25, 201623, 2018 and must comply with the rules of the SEC governing the form and content of such proposals, in order to be considered for inclusion in MEDITECH's Proxy Statement and Proxy Page.

STOCK PRICE PERFORMANCE

No public trading market exists for MEDITECH's common stock, and accordingly MEDITECH has not prepared a comparative performance graph as such. However, for shareholder reference, shown below are two comparative tables.

Table 1 shows the year-end fair share values of MEDITECH's common stock as determined by MEDITECH's Board of Directors. Because MEDITECH does not believe it can reasonably identify a group of peer issuers, it has instead included for comparative purposes the corresponding year-end values for the S&P 600 small-cap index. This table does not include any dividends received.

Table 2 shows the changes in the relative year-end values assuming an initial investment of $100 in each on December 31, 2010,2012, but includes the reinvestment of dividends received.

The information shown in the above tables is not necessarily indicative of future performance.

If any other matters should properly come before the meeting, the proxy holders have discretionary authority to vote their shares on any such matters according to their best judgment.
