Small businesses that have leaned on the Small Business Innovation Research program for decades without ever weaning off it now face a hard deadline: the Small Business Administration published a notice on September 2, 2026 setting a new minimum commercialization standard that will bar the most award-heavy SBIR and STTR recipients from competing for new Phase I or Direct-to-Phase II awards if they can't show most of their revenue comes from somewhere other than the government's own research pipeline.
The standard, issued under Section 9 of the Small Business Act, targets a narrow but award-rich slice of the SBIR/STTR universe: small business concerns that pulled in more than 25 Phase II awards, combined across SBIR and STTR and across all 11 participating federal agencies, over the five most recently completed fiscal years. For those firms, SBA will now check how much of their revenue over the three most recent fiscal years came from something other than SBIR or STTR Phase I and Phase II funding. Revenue earned under Phase III authority — the non-competitive follow-on contracts SBIR firms can win once their technology matures — counts as non-SBIR revenue for the test.
How the 25-Award Trigger and the Non-SBIR Revenue Test Work
The threshold phases in over two cycles. For the fiscal year 2027 assessment, a covered firm must show at least 33% of its revenue came from non-SBIR sources. Starting with the fiscal year 2028 assessment, and every year after, the bar rises to 50%. A company that clears the 25-award trigger but fails to hit the applicable percentage loses its eligibility to submit new SBIR or STTR proposals — not just to the agency that funded it, but to any of the program's 11 participating agencies — for one full year from the date SBA makes the determination.
The Federal Register notice spells out the consequence in plain terms: "An SBC that fails to meet the applicable minimum non-SBIR revenue share threshold is not eligible to submit a proposal for a new Phase I or Direct-to-Phase II award from any participating agency during the one-year period beginning on the date on which the determination was made." That is a program-wide freeze, not a single-agency penalty, which is what gives the standard teeth against firms that spread applications across the program's 11 participating agencies to keep the award pipeline full.
The standards take effect November 15, 2026, and also upon their publication on sbir.gov. SBA is accepting public comments through October 31, 2026. The new benchmark supersedes commercialization standards SBA had previously announced in the Federal Register at 78 FR 48537 and 78 FR 59410, meaning this is a replacement of an existing but evidently insufficient performance bar, not a brand-new concept for the program.
The "SBIR Mill" Pattern Behind the Rule
SBA's move follows years of data pointing to a small cluster of firms capturing an outsized share of SBIR/STTR funding without graduating into the commercial marketplace the program was designed to build. An SSTI analysis of SBA award data from 2009 through 2019 found that roughly 0.7% of awardees — 95 companies that had each collected 40 or more Phase I awards and/or 30 or more Phase II awards — brought in about 21% of all SBIR awards distributed across that decade. That is the population critics call "SBIR mills": firms that treat the program less as seed capital toward a commercial product and more as a recurring, government-funded revenue stream.
SSTI's analysis argued the imbalance was a policy failure as much as a company-level one, writing that "federal agencies could be doing much more to curtail the mills and redirect awards into companies more consistently focused on turning innovation into products, profits and jobs." SBA's new non-SBIR revenue test is a direct response to that critique — it doesn't cap how many awards a firm can win, but it does force firms above the 25-award trigger to prove their business has a life outside the SBIR pipeline, or lose access to new awards for a year.
Why the Test Is Measured in Revenue, Not Award Count
SBA's design choice here matters. Rather than capping awards outright, which could be read as penalizing scientific productivity, the agency is measuring commercialization outcomes — whether a firm's technology is actually generating revenue beyond the research contracts that funded its development. Counting Phase III revenue toward the non-SBIR share is notable too: it means a firm that successfully converts SBIR-funded R&D into a non-competitive follow-on production contract gets credit for that conversion, while a firm that just keeps winning new Phase I and Phase II awards without ever landing that follow-on business does not. The three-year revenue window also smooths out lumpy contract timing, so a single large non-SBIR contract award or its absence in one fiscal year won't single-handedly swing a firm's eligibility.
What It Means for Contractors
Any small business concern that has built a pattern of 25-plus combined Phase II awards across SBIR and STTR in the past five fiscal years should start tracking its non-SBIR revenue share now, well ahead of the FY2027 assessment's 33% bar. Firms sitting near that line have roughly a year before the tougher 50% threshold locks in for FY2028 and beyond, and the penalty for missing it — a one-year, all-agency freeze on new Phase I and Direct-to-Phase II submissions — can cut off a firm's entire pipeline of new awards regardless of which agency it planned to apply to next. Firms that rely on SBIR revenue as a core, ongoing business model rather than a bridge to commercialization face the most exposure and should prioritize either diversifying into commercial or Phase III revenue or reducing their award volume below the 25-award trigger. Companies with questions about how the calculation applies to their specific revenue mix have until October 31, 2026, to weigh in during the public comment period, and should watch sbir.gov for the formal publication of the standards ahead of the November 15, 2026 effective date.
