Here's the math, as I would do it.
The cannot contain more than 280 calories (because fat contains about 200 to 240 calories per ounce). Dense carbohydrate foods contain about 100 calories per ounce. All of the ingredients are dense (none are high volume for the amount of calories they provide. None are high moisture foods which contribute weight to the product without calories). As a result, it would be virtually impossible for the product to have fewer than than 125 calories (and because of the fat in the first ingredient, probably unlikely for it to contain fewer than 175 calories).
Peanut butter is all fat.
Coconut is both carbs and fat
Ingredients are (customarily) included in order of quantity, so peanut butter consists of at least 1/7 of the recipe or as much as 99%.
Coconut has some fiber, and wheat germ and oatmeal have a decent amount of fiber, but they are the last ingredients, so the smallest proportion of the recipe.
So while it's inexact, you know that the product could contain between 175 and 280 calories. The high end is more likely than the low end, because of peanut buttern being the first ingredient, so personally, I would estimate at 250 calories.
Also, if you haven't already, I would weigh each bar to make sure they are indeed 1.25 ounces, because if nutrition information is not provided, then it's likely that if they state a weight, it could be an estimate, which would throw off the calculations (as guessy as they are).
