Companies as vast and well-known as AT&T (T - Free Report) , U.S. Steel (X - Free Report) , Chipotle (CMG - Free Report) have all reported Q1 earnings after the closing bell, with typically varying results. Let's touch on a few of the highlights:

Chipotle, benefiting from a year-over-year comp relating to last year's e.coli difficulties, posted a very impressive $1.60 per share ($1.28 is what analysts had been looking for) on $1.07 billion in sales which also beat top-line expectations. Yearly comps even outperformed the positive sentiment analysts had baked into the results, increasing 17.8% from the 15.5% analysts had been looking for. Fiscal year forecasts are up, and so are CMG share in the after-market, +4.5%. For more, click here.

AT&T just met earnings estimates on the bottom line to 74 cents per share on quarterly revenues that fell short of the Zacks consensus -- $39.37 billion versus the $40.66 billion expected. The telecom major was happy to report its lowest Q1churn ever, but missed on net add expectations slightly to 2.7 million in the quarter.

U.S. Steel, however, a Zacks Rank #1 (Strong Buy) stock ahead of its earnings announcement, posted a deeply disappointing -83 cents per share. Analysts had been looking for +32 cents, so a huge $1.15 swing has led late-market trading to the downside. Revenues also missed -- $2.72 billion instead of the $2.92 billion expected. Many had thought the combination of "Buy American" and infrastructure spending in 2017 and beyond would have helped bolster the stock in Q1, but such does not appear to have been the case.

Global gaming giant Wynn Resorts (WYNN - Free Report) saw a rebound in Macau businesses leading to a beat on top and bottom lines. Earnings of $1.24 per share trounced the 74 cents expected, and quarterly sales of $1.48 billion easily topped $1.35 billion in the Zacks consensus. This is the first quarter in the last 3 where the Zacks Rank #3 (Hold) stock has beaten bottom-line estimates.
