How should the PRTK historical PE ratio be determined?
Realizing that PE stands for Price to Earnings ratio, we need two values to compute it: stock price and earnings per share. The stock price at any given date is a known historical value, but what about the earnings number to use?

✔️Accepted answer: There are a number of different approaches when it comes to calculating a historical PE ratio for a company like Paratek Pharmaceuticals. We like to take our measurements on each of the past quarterly earnings reports. That only leaves the question of whether the earnings number at that quarterly report should be used on an annualized basis, or some other method. We approach this question using three different methods, on this PRTK Historical PE Ratio page.

What is the average historical PE for PRTK based on annualized quarterly earnings?
As we look back through earnings history, what is the resulting PE calculation if at each measurement period we use that quarter's earnings result annualized?

✔️Accepted answer: The PRTK historical PE ratio using the annualized quarterly earnings method works out to 7.2.

What is the average historical PE for PRTK based on trailing twelve month earnings?
As we look back through earnings history, what is the resulting PE calculation if at each measurement period we use the trailing twelve months combined earnings result in the calculation?

✔️Accepted answer: The PRTK historical PE ratio using the TTM earnings method works out to NA.

On this page we presented the PRTK Historical PE Ratio information for Paratek Pharmaceuticals' stock. The average PRTK historical PE based on using the annualized quarterly earnings result at each measurement period (for the "E" in the PE calculation; and the closing price on earnings date as the "P") is 7.2. Meanwhile, using the trailing twelve month (TTM) quarterly earnings result as our method of calculation the "E" value at each measurement period, the average PRTK historical PE based on this TTM earnings result method is NA. Note: any PE calculations involving negative earnings were discarded as not meaningful.

Let's now compare this PRTK historical PE result, against the recent PE: when this page was posted on 11/4/2022, the most recent closing price for PRTK had been 2.53, and the most recent quarterly earnings result, annualized, was 0.8. Meanwhile, the most recent TTM earnings summed to NA. From these numbers, we calculate the recent PRTK PE on 11/4/2022 based on annualized quarterly EPS was 3.2. Based on PRTK's history, that recent PE is low relative to the historical average, with the recent PE 55.6% lower than the historical average PE across our data set for Paratek Pharmaceuticals.

For self directed investors doing their due diligence on PRTK or any other given stock, valuation analysis for PRTK can greatly benefit from studying the past earnings and resulting PE calculations. This exercise can help inform an analysis as to whether the past earnings trajectory and current versus historical PE ratios justify the current stock value.
