We develop an approach based on the light-cone sum rules at the leading order of ${\alpha }_S$ to calculate the gravitational form factors $\mathbb{A}(t)$ and $\mathbb{B}(t)$ for the valence quark combinations in a nucleon. Within the proposed model, the predictions for the gravitational form factor $\mathbb{D}(t)$ ($D$-term contributions) have been presented. Comparison with the experimental data and with the results of different models is discussed.
