Management Commentary
“The AI Datacom opportunity has grown significantly,
with some market analysts projecting the Data Center IT Semiconductors and Components market will surpass $1.8 trillion in 2030,”
said Jonathan Klamkin, Ph.D., Founder and CEO of Aeluma. “With photonic interconnects being an important part of data center investments,
scalable high-speed photodetectors and quantum dot lasers have become the focus of the Company’s near-term product development.”
“After establishing a foundation for commercialization
in fiscal 2026 that included more than doubling the size of our team, establishing strategic manufacturing partnerships, and bolstering
cash, the Company is transitioning from early-stage R&D Government contracts to a focus on scale and commercialization. To this end,
we announced a letter of intent (LOI) with the Department of Commerce CHIPS R&D Office for up to $30 million to accelerate development
and commercialization for AI and advanced computing, we established relationships with manufacturing supply chain partners, and we advanced
our customer engagements.”

“Fiscal 2027 will focus on technology and
product development, and expanding our customer engagements. We are in discussions with several important prospective customers in the
AI datacom industry, negotiating NRE agreements that could support our go-to-market strategy. We will continue to grow our team, we are
adding MOCVD wafer production capacity, and we executed an important agreement to expand our relationship with supply chain partner Sumitomo
Chemical Advanced Technologies. We believe it is timely to make these investments given the projected scale of our market opportunities,
and our customers are aligned with our strategy. Finally, the CHIPS R&D funding, which is subject to definitive agreement negotiations,
could accelerate our commercialization timeline,” concluded Dr. Klamkin.

than director nominations) for inclusion in Aeluma’s proxy materials relating to the Annual Meeting must follow the procedures provided
in Rule 14a-8 and our bylaws. To be timely, such proposals must be delivered to or mailed and received by our corporate secretary on or
before the close of business on September 26, 2026, which is a reasonable time before printing and mailing of our proxy materials for
the meeting.
Stockholders who intend to propose an item of

a person for election as a director at the Annual Meeting, must provide timely written notice of such proposal or nomination. To be timely
under our bylaws, such notice also must be delivered to or mailed and received by our corporate secretary no later than the close of business
on September 26, 2026, and must contain the information specified in our bylaws.
In addition to satisfying the foregoing requirements

under the Exchange Act, no later than September 26, 2026.
Non-GAAP Financial Measures
This press release includes the following non-GAAP financial measures:
| ● | Non-GAAP net income (loss), which is defined as net income (loss) plus stock-based compensation expenses,
amortization of discount on convertible notes, and changes in fair value of derivative liabilities; and |
| ● | Adjusted EBITDA, defined as non-GAAP net income (loss) plus depreciation and amortization expenses, less
interest income. |
The presentation of these financial measures is
not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with
U.S. generally accepted accounting principles (“GAAP”). We believe that the presentation of these non-GAAP financial measures
provides important supplemental information to management and investors regarding financial and business trends relating to Aeluma’s
financial condition and results of operations. We believe that these non-GAAP financial measures provide additional insight into Aeluma’s
ongoing performance and core operational activities and provide these measures for more consistent and meaningful comparison between periods.
These measures should only be used to evaluate Aeluma’s results of operations in conjunction with the corresponding GAAP measures.
A reconciliation of each non-GAAP financial measure
to its most directly comparable financial measure calculated and presented in accordance with GAAP is provided in the financial statements
portion of this press release.

Forward-Looking Statements
This press release contains forward-looking statements
within the meaning of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and other securities laws. All
statements in this press release that are not historical are forward-looking statements, including, among other things, potential applications
and resulting benefits of Aeluma’s technology, timing of development and commercialization of Aeluma’s products, anticipated
demand and markets for Aeluma’s products, whether Aeluma or the U.S. Department of Commerce will enter into definitive award documents
on acceptable terms, or at all, whether Aeluma will receive or retain any portion of the proposed CHIPS funding, and the potential issuance
of Company securities to the U.S. Department of Commerce. These statements are not historical facts but rather are based on Aeluma’s
current expectations, estimates, and projections regarding its business, operations, and other similar or related factors. Words such
as “anticipate,” “could,” “growing,” “intend,” “may,” “plan,”
“poised,” “potential,” “will,” “would,” and other similar or related expressions are used
to identify these forward-looking statements, although not all forward-looking statements contain these words. These forward-looking statements
are neither promises nor guarantees, and you should not place undue reliance on forward-looking statements because they involve known
and unknown risks, uncertainties, and assumptions that are difficult or impossible to predict and, in some cases, beyond Aeluma’s
control. Actual results may differ materially from those in the forward-looking statements as a result of a number of factors, including
Aeluma’s history of losses and limited operating history, and its ability to achieve or sustain profitability; competitive, technological,
and market risks affecting the adoption of Aeluma’s semiconductor and photonics products for AI, high-performance computing, and
other target markets; general economic, geopolitical, and supply-chain conditions affecting the semiconductor industry; uncertainty as
to whether Aeluma and the U.S. Department of Commerce will establish and execute definitive award documents for the proposed funding on
acceptable terms, or at all; uncertainty as to whether, when, and in what amount Aeluma will receive or retain any portion of the proposed
funding; the perceived and actual dilutive effects of the proposed issuance of common stock; impacts of an equity stake by the U.S. government
in Aeluma, including any related reputational, regulatory, or governance considerations; Aeluma’s ability to satisfy applicable
milestones associated with the funding; the risk that anticipated benefits of the proposed funding, including acceleration of commercialization
and scaling of Aeluma’s non-InP photonics platform, may not be realized on the timeline anticipated or at all; changes in U.S. government
policy, funding priorities, or budgetary constraints that could affect the availability or continuation of CHIPS programs; and other risks
described in Aeluma’s filings with the U.S. Securities and Exchange Commission. Aeluma undertakes no obligation to revise or update
information in this release to reflect events or circumstances in the future, even if new information becomes available, except as required
by law.
