The increases in G&A expenses in 2019 are primarily attributable to growth in employee costs, including non-cash share-based compensation associated with increases in the number of G&A personnel, and increases in consulting and professional services related to the expansion of our business activities.
• Net Loss Attributable to Common Stockholders: As of September 30, 2019, SpringWorks reported net losses of $16.8 million, or $1.77 loss per share, and $34.4 million, or $9.24 loss per share, for the third quarter and year-to-date periods respectively.
