Working with McDonalds Stock Split History
When people ask about McDonalds Stock Split History, they usually want one of two things: they either need the raw facts for a school project or personal research, or they are trying to adjust cost basis on old shares. The second group is where things get messy. I ran into this problem recently when reviewing a client's portfolio from the 1990s. The brokerage platform showed adjusted prices going back only to the late 1990s, which meant any shares bought before that window were completely unadjusted on the interface. I had to manually reconstruct the splits myself using NASDAQ's historical data and cross-reference it with SEC filings. McDonald's (ticker: MCD) has executed a total of 12 stock splits since its IPO in 1965. The company went through a rapid split phase in the late 1960s and 1970s, which was typical for fast-growing companies of that era. The splits occurred on the following dates: May 1967 – 2-for-1 split
October 1968 – 2-for-1 split
June 1969 – 2-for-1 split
June 1970 – 2-for-1 split
May 1971 – 2-for-1 split
April 1972 – 2-for-1 split
March 1973 – 2-for-1 split
February 1974 – 2-for-1 split
January 1975 – 2-for-1 split
December 1976 – 2-for-1 split
January 1987 – 2-for-1 split
After that, the company went nearly three decades without another split. McDonald's executed its next split in April 2013, a 2-for-1, which was notable because it came after a long drought. Then came the most recent split in July 2022, also 2-for-1. Between 1987 and 2013, the stock price appreciation alone was substantial enough that the board apparently decided no additional splits were necessary until the share price climbed back into the high $200 range again.
How to Access the Full Historical Data
The most reliable free source for this information is the Nasdaq website. You can go to their investor relations section, search for MCD, and pull the historical dividend and split data. Yahoo Finance also has a solid record, though I have found occasional discrepancies in the exact dates compared to Nasdaq. The SEC's EDGAR database has the official proxy statements and press releases from each split announcement, which is the gold standard if you need primary-source verification. I used the SEC filings approach when a client disputed the number of shares they should have after the 2013 split. The brokerage's adjusted cost basis was off by a small fraction due to how they rounded the conversion. Going to the April 2013 press release on EDGAR confirmed the exact ratio and record date, and we corrected the account accordingly. It took about ten minutes to find and read the relevant document.

Common Pitfalls People Miss
One thing most people get wrong is assuming that all McDonald's splits are simple 2-for-1 ratios. They are, but the compounding effect over twelve splits means one pre-1967 share is now worth 8,192 shares (2 to the 13th power). Not that anyone alive owns pre-IPO shares, but the math matters when you are back-testing returns or comparing a buy in 1970 to today. Another pitfall is ignoring the difference between the announcement date, the record date, and the payable date. Most data sources list the payable date, which is the day the split actually takes effect in your account. If you are calculating cost basis adjustments, you need the payable date, not the announcement date. I have seen people use the wrong date and end up with slightly wrong share counts, especially when dealing with shares purchased near the record date of a given split. There is also a limitation with reverse stock splits that does not apply to McDonald's but comes up often in discussions like this. Some investors assume McDonald's has never done a reverse split, which is correct, but when researching split history in general, you need to be careful not to conflate the two. A forward split increases your share count and lowers the price. A reverse split does the opposite. McDonald's has only done forward splits, so you do not have to worry about that complication here.
What This Means in Practice
If you bought 100 shares of McDonald's at the IPO price of $22.50 in 1965 and held through every split, you would own 8,192 shares today. That is the kind of long-term holding return that makes historical split data actually useful rather than just trivia. For more recent investors, the 2013 and 2022 splits matter more for position sizing and tax lot tracking. The main practical takeaway is this: if your broker shows incomplete adjusted history, do not trust the platform to have it right automatically. Verify against Nasdaq or the SEC filings, especially for anything predating the 1990s. The data exists, it is public, and it is free. It just takes a little effort to pull it together correctly.
