IMPACT
One (very large) group of people
thinks that using “impact” as a verb is just nifty:
“The announcement of yet another bug in the software
will strongly impactthe price of the company’s stock.”
Another (very passionate) group of people
thinks that “impact” should be used only as a noun
and considers the first group to be barbarians.
Although the first group may well be winning the usage struggle, you risk offending more people
by using “impact” as a verb
than you will by substituting more traditional words
like “affect” or “influence.”

Is impact a verb?
Noun
You may occasionally run into claims that impact is not a verb,
or that it is somehow ill-suited to a role in this part of speech.
Not only is that not the case, but the verb form of impact
is much older than the noun form.
It is possible that the word started attracting more displeasure when it began being widely used in a figurative sense
as a transitive verb
("we expect the recession to impact the company").
The word is certainly a verb,
although before using it in this manner in writing
it is worth considering your audience,
and whether members of it
are likely to consider this use problematic.

Usage Notes
Yes, 'Impact' Is a Verb
The verb got there first
It sometimes seems as though we base our usage guidelines
for the English language on the same principle of fairness
that we use for squabbling children.
While this may be of some limited efficacy
when dealing with one’s progeny
—“Now Billy, I know you wanted to be an astronaut for Halloween, but you already chose the superhero costume, and Clara has had her heart set on being an astronaut for weeks now....”
—it tends to run into problems when we apply it to issues of language
(“Now impact, I know you wanted to be a verb,
but you already picked out your noun costume,
and affect has been a verb for decades now…”).
Evidence of the verb 'impact' predates evidence of the noun
by approximately 200 years.
The notion that impact should not be used
as a verb is a fairly common one.
There are some compelling stylistic arguments
against some of this word’s current uses,
and there are some not-so-compelling ones.
Here are some of the not-so-compelling ones.
Impact is a noun, not a verb.
—Richard Block, The Santa Fe New Mexican (Santa Fe, NM), 2 Feb. 2002
There was a lonely time, long ago, when meteors came streaming out of the sky and made a big impact. I am your true antique, for I can recall when impact was not a verb. Nowadays, something is always impacting something else, and emphatically I am not talking of operations in the dentist's office. Impact, the verb, is merely a pseudo-technical dressup, a feeble attempt to make the obvious seem refined, or remote, or special. It is more weaselry.
—Rex Murphy, The Globe and Mail (Toronto, Ont.), 6 Jan. 2001
Impact players really do exist and every good team needs one, but "impact" is not a verb and it never will be.
—Paul Woody, Richmond Times Dispatch, 2 Jan. 2000
What's wrong with these statements?
After all, many doughty and fearless defenders of English believe that impact should not be used as a verb,
and our language, in its typical munificence,
has supplied us with many verbs which one may use instead
(such as affect, impinge, influence, etc.).
The problem with saying that a certain word
is never used as a certain part of speech is that pesky things
like evidence tend to refute such blanket statements.
Impact has been in regularuse as a verb
for well over 400 years now;
its earliest uses were primarily to describe problems
with the way the body functioned
(dealing with impacted teeth, bowels, and suchlike)
which no one needs to read about over lunch,
so we’ll omit giving you graphic citations of this use.
If the verb form of impact is so much older than the noun form, why did we decide that it was somehow improper?
One possibility is that the figurative use is
what rubbed people the wrong way.
Impact began to be used figuratively as a noun
(referring to “effect,” rather than “collision”)
in the early 19th century.
In the early 20th century the verb followed down
the figurative path, and when used in an intransitive manner
(“to have an impact”) people began to complain about it.
In the late 20th century the figurative uses of impact
increased considerably, which likely contributed
to the feeling that use of the word as a verb
was a recent development.
At the technology session that impacted on
the development of electronic publishing….
—Publishers Weekly, 1 Jan. 1982
This need to hold stock for 12 months will impact mutual funds.
—Robert Lenzer, Barron’s, 20 Dec. 1976
It isperfectly reasonable to dislike this use of the word,
and to argue that other words would be better choices.
However, to claim that something that has been used as a verb for over four centuries is not actually a verb is, we must point out, a logically indefensible position.
Whether you choose to use impact as a verb is up to you.
If you decide to err of the side of caution,
no one will fault you for your choice.
Impact has also seen extensive use as an adjective
over the past few hundred years, but if you feel
the need to made some definitive statement about this word,
we may suggest that you can feel comfortable
in declaring in stentorian tones the following:
“Impact is not an adverb!” No one will fault you on that.

Impact & Impactful
Impact is often viewed as not being a verb,
despite the fact that it people have been using it as one
since the 16th century.

Usage Note:
Impact in the figurative sense of "a dramatic effect"
came under criticism in the 1960s, both as a noun and verb.
Complaints that the noun was a pointless hyperbole
and a vogue word turned out to be short-lived,
and this usage is now is standard:
in our 2015 survey, 97 percent of the Usage Panel accepted
The program might have a positive impact on our nation's youth.
(A similar sentence was accepted by 93 percent
of the Panel in 2001.)
The verb is a different matter.
Many people dislike it because they assume
it was converted from the noun in
the manner of voguish and bureaucratic words
like dialogue and interface,
but in fact impact was a verb long before it was a noun
—the verb dates from the early 1600s,
the noun from the late 1700s.
Most of the Panelists still disapprove of the intransitive
use of the verb meaning "to have an effect":
in our 2015 survey, 78 percent of the Panel
(down only slightly from 85 percent in 2001)
rejected These policies are impacting on our ability to achieve success.
The transitive version was once as vilified,
but is gradually becoming more acceptable:
in 2015, only 50 percent (down from 80 percent in 2001) rejected
The court ruling will impact the education of minority students, and only 39 percent (down from 66 percent in 2001) found the literal sense unacceptable in the sentence
Thousands of meteors have impacted the lunar surface.
Although resistance to the transitive senses is waning,
the intransitive use is still strongly disliked and is best avoided. See Usage Notes at contact, impactful.
Random House Kernerman Webster's College Dictionary,
usage:
The verb impact has developed the transitive sense
“to have an impact or effect on”
(The new reading program has impacted the elementary schools favorably)
and the intransitive sense “to have an impact or effect”
(Our work here impacts on every department in the company)
These uses, though common, are often harshly criticized.
