Yes. The sentence can be written “provides suppliers” or “provides suppliers WITH.” It means the same thing either way; the “with” is implied. Another example: “This place provides visitors [with] a sense of peace.” The “with” can be omitted. In fact, so can “visitors”: “This place provides a sense of peace.” It is understood from context that it is “visitors” who get the sense of peace.

Many English verbs allow two forms: [verb] [direct object] TO [indirect object] and [verb] [indirect object] [direct object]. Examples: I provided the information to the customer. I provided the customer the information.

It can be used that way as well - provide something. Provide for somebody, provide for something, provide against are also possible
