I think the crucial distinction between a slight stretch like you describe and what Holmes did is the tense: the military is going to test our product vs. the military is testing our product (which did not, uh, exactly exist then). One is a rosy forecast and the other is just a lie.
But as I understood it, that's not what she said. Your phrasing is about the future, i.e. something nobody can know at the time it is being said whether it will come true or not. Therefore, something anyone with the least bit of common sense would think "Yeah, let's hope that will happen" about.
Completely different than saying "the military is running / has run a test with our equipment". That's a statement of actual ongoing or concluded fact. If it actually is happening or has happened when you say it is happening or has happened, then you're telling the truth; if it isn't / hasn't, then it's a lie.
From what I gather, what she said was the latter -- but it never actually happened: So, a lie. Said with intent to induce people to give her money: So, fraud.
tbqh, I came away from the trial really feeling like the investors who testified against her deserved what they got because of how they approached the situation. IMO Elizabeth Holms isn't some mastermind manipulator, she's more akin to a child who was enabled by moronic parents.
