Altera

<c:forEach items="${empresas}" var="empresa">
            <li> ${empresas.nome }</li>
        </c:forEach>

Para:

<c:forEach items="${empresas}" var="empresa">
            <li> ${empresa.nome }</li>
        </c:forEach>

Alterei mas o erro no navegador persiste

Na sua classe Empresa tem a propriedade nome, os getters e setters?

tem sim

package br.com.gerenciador.servlet;

import java.util.Date;

public class Empresa {
    private Integer id;
    private String nome;
    private Date dataAbertura= new Date();


    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getNome() {
        return nome;
    }
    public void setNome(String nome) {
        this.nome = nome;
    }
    public Date getDataAbertura() {
        return dataAbertura;
    }

}

Deixa eu ver o método de listar na classe Banco

Classe Banco Completa

package br.com.gerenciador.servlet;

import java.util.ArrayList;
import java.util.List;

public class Banco {
    private static List<Empresa> lista = new ArrayList<>();

      static {
            Empresa empresa = new Empresa();
            empresa.setNome("Alura");
            Empresa empresa2 = new Empresa();
            empresa2.setNome("Caelum");
            lista.add(empresa);
            lista.add(empresa2);
        }

    public void adiciona(Empresa empresa) {
        lista.add(empresa);
        System.out.println("Empresa cadastrada no banco");
    }
    public List<Empresa> getEmpresas(){
        return Banco.lista;
    }
}
