# Text misaligned in multicolumn

I am trying to have part of the page divided into three columns and in each one a centered title and a description of different length. The problem is that the start of the bottom of the descriptions are misaligned, I am using the multicols package and \columnbreak between each. What should I change?

\begin{multicols}{3}
\begin{center}\textbf{Company 1}\end{center}
The company is based in XX, XX, the core business bla bla bla blaaaa bla bla. It is a public owned company where XXX XXX holds 100\% of the shares. Therefore its development is valuable for the municipality's growth strategy of the East area.
\columnbreak

\begin{center}\textbf{Company 2}\end{center}
The company is based in XXX, XXX, where produces bla bla blaaaaa blaaa, being one of the major worldwide producers of the latter one. It is part of the XXX Holding S.p.A. since XX. It directly provides XXX jobs, not to mention the indirect jobs and contractors \citep{blablabla}.
\columnbreak

\begin{center}\textbf{Material}\end{center}
The material exchanges in this synergy is the XXX XXX coming from the bla bla blaaaa blaaa. It is necessary in order to allow bla bla to be able to blaaaaa it, without this action, the blaaa would lose blaaa and the blaaaaa would get blaaa in it. It is reused in the xxx xxxx as raw material. Before this partnership the blaaa blaaaaa was collected and bla blaaa blaaa blaaaa.
\columnbreak

\end{multicols}


You can use paracol instead of multicol; the package is precisely aimed to typeset text in independent columns.

\documentclass{article}
\usepackage[a4paper]{geometry} % more generous line width
\usepackage{microtype}
\usepackage{paracol}

\usepackage{lipsum}

\begin{document}

\lipsum[3]

\begin{paracol}{3}
\sloppy
\begin{center}\textbf{Company 1}\end{center}
The company is based in XX, XX, the core business bla bla bla
blaaaa bla bla. It is a public owned company where XXX XXX
holds 100\% of the shares. Therefore its development is valuable
for the municipality's growth strategy of the East area.
\switchcolumn

\begin{center}\textbf{Company 2}\end{center}
The company is based in XXX, XXX, where produces bla bla blaaaaa
blaaa, being one of the major worldwide producers of the latter
one. It is part of the XXX Holding S.p.A. since XX. It directly
provides XXX jobs, not to mention the indirect jobs and contractors.
\switchcolumn

\begin{center}\textbf{Material}\end{center}
The material exchanges in this synergy is the XXX XXX coming from
the bla bla blaaaa blaaa. It is necessary in order to allow bla
bla to be able to blaaaaa it, without this action, the blaaa would
lose blaaa and the blaaaaa would get blaaa in it. It is reused in
the xxx xxxx as raw material. Before this partnership the blaaa
blaaaaa was collected and bla blaaa blaaa blaaaa.
\end{paracol}

\lipsum[3]

\end{document}


It's always best to include a complete example code, from \documentclass{whatever} to \end{document}, because the effects you see may be caused by packages, definitions, etc. that are not part of your code fragment. However, I think you need \raggedcolumns.

\documentclass{article}
\usepackage{multicol}
\begin{document}
\begin{multicols}{3}
\raggedcolumns
\begin{center}\textbf{Company 1}\end{center}
The company is based in XX, XX, the core business bla bla bla blaaaa bla bla. It is a public owned company where XXX
XXX holds 100\% of the shares. Therefore its development is valuable for the municipality's growth strategy of the
East area.
\columnbreak

\begin{center}\textbf{Company 2}\end{center}
The company is based in XXX, XXX, where produces bla bla blaaaaa blaaa, being one of the major worldwide producers of the latter one. It is part of the XXX Holding S.p.A. since XX. It directly provides XXX jobs, not to mention the indirect jobs and contractors \cite{blablabla}.
\columnbreak

\begin{center}\textbf{Material}\end{center}
The material exchanges in this synergy is the XXX XXX coming from the bla bla blaaaa blaaa. It is necessary in order to allow bla bla to be able to blaaaaa it, without this action, the blaaa would lose blaaa and the blaaaaa would get blaaa in it. It is reused in the xxx xxxx as raw material. Before this partnership the blaaa blaaaaa was collected and bla blaaa blaaa blaaaa.
\columnbreak

\end{multicols}
\end{document}


Using a multicols environment here might more than just a bit abusive. I recommend using three side-by-side minipage environments.

\documentclass{article}

\usepackage{natbib}
\raggedbottom
\begin{document}
\noindent
\begin{minipage}[t]{0.31\textwidth}
\begin{center}\textbf{Company 1}\end{center}
The company is based in XX, XX, the core business bla bla bla blaaaa bla bla. It is a public owned company where XXX XXX holds 100\% of the shares. Therefore its development is valuable for the municipality's growth strategy of the East area.
\end{minipage}%
\hspace{\fill}
\begin{minipage}[t]{0.31\textwidth}
\begin{center}\textbf{Company 2}\end{center}
The company is based in XXX, XXX, where produces bla bla blaaaaa blaaa, being one of the major worldwide producers of the latter one. It is part of the XXX Holding S.p.A. since XX. It directly provides XXX jobs, not to mention the indirect jobs and contractors \citep{blablabla}.
\end{minipage}%
\hspace{\fill}
\begin{minipage}[t]{0.31\textwidth}
\begin{center}\textbf{Material}\end{center}
The material exchanges in this synergy is the XXX XXX coming from the bla bla blaaaa blaaa. It is necessary in order to allow bla bla to be able to blaaaaa it, without this action, the blaaa would lose blaaa and the blaaaaa would get blaaa in it. It is reused in the xxx xxxx as raw material. Before this partnership the blaaa blaaaaa was collected and bla blaaa blaaa blaaaa.
\end{minipage}
\end{document}


I propose using tabularx – more exactly ltablex which adds the functionalities of longtable to tabularx.

\documentclass{article}
\usepackage[showframe]{geometry}
\usepackage{natbib}
\usepackage{ltablex} %brings the functionalities if longtable to tabularx
\usepackage{makecell}
\raggedbottom

\begin{document}

{\setlength{\tabcolsep}{0.5\columnsep}
\begin{tabularx}{\textwidth}{@{}XXX@{}}
\medskip
The company is based in XX, XX, the core business bla bla bla blaaaa bla bla. It is a public owned company where XXX XXX holds 100\% of the shares. Therefore its development is valuable for the municipality's growth strategy of the East area.
