I'm unsure if my question meets the standards of a typical WSO question, but I figure it's worth a try! I'm currently in the data-gathering process for a research paper concerning the effect of corporate culture on the success rate of modern-day mergers and acquisitions; I am co-authoring the research paper with my professor, and would highly appreciate a little guidance in the right direction.

We are looking at the Dow Jones 30 for our initial data set (just to get our feet wet). My job this past weekend has been to utilize the EDGAR SEC database and search for DEFM14C filings for these 30 companies; I figured that by doing this, I would easily find out the companies in the DJ 30 with any M&A activity in the past 13 years.

Unfortunately, I have only been able to find DEFM 14A filings, and while some of them are fairly obvious (Exxon Mobil's 1999 merger, for instance), I cannot rely on DEFM 14A forms alone to serve as an indicator of a successful merger/ acquisition. I will later be dealing with much larger data sets, so I need a full-proof and streamlined method of collecting data.

Is there any online database, feed site, or readily available collection of press releases on mergers and acquisitions that I could utilize? I have some working knowledge of Ruby's Anemone and Nokogiri gems, but I was hoping that I would not have to resort to web crawling to find the information I'm looking for.

Again, sorry if this is not the forum to post such a question, but I would highly appreciate any and all advice/ information. Thank you!!

I mean Thomson One's M&A database is fairly comprehensive (at least of public deals; don't overlook transactions, which may or may show up in Thomson or any other source) with respect to dates, price.. basically, whatever was on the term sheet. But I think this sort of analysis has already been done? See the following links.

This type of analysis has been done already. Many times.

CapIQ > Thomson IMO.


Thanks for the help! And yes, I understand it has been done, but it's not what I'm doing; I wasn't just about to post on a public forum exactly what I'm researching. Thanks for the links though.


See if your business school library has access to Capital IQ.

If so, just search your favorite buyer and click on "M&A/Private Placements" on the left side.

You could also just screen mergers/acquisitions on capital IQ. Screening > Transactions and put in your constraints.


There are many online database, feed site, collection of press releases available on the internet you can use in your research, you just try to find them using google.



"The market for acquisitions is highly segmented; returns to investors vary significantly across the segments. For this reason, broad assertions about M&A success and failure are less meaningful. All M&A is local: pay attention to the peculiarities of the deal including its motives, design, context, and implementation." - Deals from Hell

Also, there is probably some decent Organizational change & development (HR) papers that could offer insight to the challenges you are seeking to isolate.


There are numerous different resources we use to find relevant information on Mergers and Acquisitions. The first and most useful tool is Investment Bank. Push the search button and then type merger and acquisition. You will access the biggest offers in the market and also the investment banks who are working on the deals. You will also see the price of the deal and the several industries that potentially need to merge or acquire.
