IRONHIGH SIGNALFINANCIAL10-K

IRON's R&D and SG&A expenses nearly doubled while net losses increased 94%, despite a significant increase in assets and equity suggesting a major capital raise.

The company appears to have raised substantial capital (evidenced by the 67% increase in stockholders' equity and 62% asset growth) but is burning through cash at an accelerated rate with operating cash flow losses doubling to -$180.4M. The removal of language about seeking FDA Accelerated Approval and the addition of warnings about narrower patient populations and unclear voucher benefits suggests regulatory setbacks that may be driving increased spending without corresponding progress.

FINANCIAL ANALYSIS

IRON experienced dramatic expense growth with R&D costs rising 77% to $170.6M and SG&A nearly doubling to $65.4M, resulting in net losses expanding 94% to -$212.2M and operating cash flow deteriorating 92% to -$180.4M. However, the company significantly strengthened its balance sheet with stockholders' equity increasing 67% to $739.8M and total assets growing 62% to $806.9M, indicating a major capital infusion. This presents a mixed picture of substantial new funding offset by concerning acceleration in cash burn rates that investors should monitor closely.

As of February 19, 2026, there were 38,160,065 shares o f the registrant s Common Stock, $0.0001 par value per share, outstanding.
Because we are developing some of our product candidates for the treatment of diseases in which there is little clinical experience and, in some cases, using new endpoints or methodologies, the FDA or other regulatory authorities may not consider the endpoints of our clinical trials to predict or provide clinically meaningful results.
iv If the market opportunities for our product candidates are smaller than we estimate or if any regulatory approval that we obtain is based on a narrower definition of the patient population, our revenue and ability to achieve profitability could be materially adversely affected.
If we fail to comply with our obligations in any agreements under which we may license intellectual property rights from third parties or otherwise experience disruptions to our business relationships with our licensors, we could lose license rights that are important to our business.
We received a Commissioner s National Priority Voucher for bitopertin but the accelerated timeline for review of our NDA submission for bitopertin in EPP and XLP by the FDA did not result in an approval and it is unclear what, if any, benefits this voucher may provide in the future.

REMOVED
As of February 21, 2025, there were 34,569,042 shares of the registrant s Common Stock, $0.0001 par value per share, outstanding.
We may seek approval from the FDA for bitopertin or any of our other current or future product candidates under the Accelerated Approval Program.
If we are not able to use such program, we may be required to conduct additional clinical trials beyond those that are contemplated, which would increase the expense of obtaining, and delay the receipt of, necessary marketing approvals, if we receive them at all.
In addition, even if the Accelerated Approval Program is available to us, it may not ultimately lead to expedited approval of our product candidates, or approval at all.
Unfavorable global economic conditions could adversely affect our business, financial condition or results of operations.
