Ladies and gentlemen, the creation of this new department will increase productivity and help the company to become ____________ again.

The word "profitable" is the correct choice because it describes a state in which a company earns more money than it spends, thus indicating financial success when combined with "increase productivity." In the context of the sentence, the goal of creating a new department is explicitly to improve the company's financial situation.

Other options do not fit appropriately in this context. "Provider" refers to someone or something that supplies goods or services, which does not convey the intended meaning of the company’s financial state. "Profitless" suggests a lack of profit, which is contradictory to the goal of the department’s creation. "Profound" relates to something of great depth or intensity but does not pertain to financial performance. Hence, "profitable" aligns perfectly with the intent of the sentence.
